Chinese Shang Ring adult male circumcision (SC) is a safe and effective procedure which is easy to learn and to perform. By a specially designed small device, male circumcision (MC) can be performed in 5 min. Compared with conventional adult MC (CC), SC has shorter operation time, less blood loss, less pain score, higher appearance satisfaction rate, and lower complication rate. SC was first developed in China. As recent studies have demonstrated that MC reduced the risk of acquiring human immunodeficiency virus (HIV) infection via vaginal intercourse in African countries, SC was introduced into Africa to fight HIV. Other sexually transmitted diseases such as human papillomavirus infection may also be prevented by SC. In conclusion, Chinese Shang Ring, a small device, provides an easy, quick, safe, and effective method to perform adult MC.
Circumcision is an operation to remove a male’s foreskin. It is one of the oldest and most common surgical procedures. A male may undergo this procedure for religious, social, medical, or cultural reasons.
The Centers for Disease Control and Prevention (CDC) encourage male circumcision on the basis that it appears to reduce the risk of HIV infection during vaginal sex. However, not all health authorities agree, and the recommendations remain somewhat controversial.
Adult circumcision device is fairly commonly used in the United States. In fact, according to the CDC, 58.3%Trusted Source of U.S. newborns underwent circumcision in 2010.
It is less common in other Western countries, however. In the United Kingdom, for example, only around 8.5% of males are circumcised.
This article will discuss what to expect during the procedure itself, as well as some possible benefits and risks.
What is circumcision?
Circumcision involves the removal of the foreskin of the penis. The foreskin is the shroud of skin that, when gently pulled back, uncovers the head of the penis.
The surgery is relatively simple. A healthcare professional will free the foreskin from the head of the penis and, in newborns, clip it off in a procedure that only takes a few minutes. In adults, they will remove the foreskin with a scalpel, and it takes around 30 minutes.
They will then either cauterize or stitch the wound with dissolvable sutures.
History
The first circumcisions may have taken place around 15,000 years ago. The procedure then slowly spread across a variety of cultures, especially in the Middle East.
It may have become popular in the ancient world as a public health measure and a way of preventing balanitis. Balanitis leads to swelling and pain in the head of the penis.
This condition might have been more common in ancient societies due to sand building up under the foreskin.
Circumcision became popular in the Western world in the late 19th century, when people began performing the operation in an attempt to prevent masturbation. Many believed that masturbation was associated with conditions such as epilepsy, paralysis, tuberculosis, and insanity.
However, there was little compelling evidence to support these claims. As the newly formed national healthcare systems started facing rising costs, they stopped recommending the procedure.
In the U.S., however, it has remained a relatively common practice, and some major health authorities do still encourage it.
Why circumcise newborns?
A number of factors are associated with neonatal circumcision.
The most common are: - religion
- hygiene
- health considerations
Some studies have suggested that circumcision reducesTrusted Source the risk of urinary tract infection, but more recent findings have contradicted this, with some suggesting that it might actually increase the risk.
Evidence has indicated a lower risk of some sexually transmitted infections (STIs), including syphilis. Circumcised males, using male circumcision device, also appear to be less likely to contract herpes or HIV.
In very rare cases, balanitis or phimosis can develop in an uncircumcised male. With these conditions, the foreskin cannot retract. This requires surgical treatment.
Cancer of the penis is extremely rare, but it appears to be slightly more commonTrusted Source in males with a high body mass index (BMI), males with a history of smoking, males who are uncircumcised, and those with a combination of these factors.
Adult circumcision
Circumcision is less common in adults than in children. It takes longer and is likely to involve more tissue trauma. It may also cause more psychological trauma than it does in newborns.
However, it may reduce the risk of certain conditions, including phimosis, paraphimosis, and balanitis.
Phimosis is the inability to pull back the foreskin, leading to pain and urinary problems. It can occur if a male is born with a tight foreskin, or due to scarring, infection, or inflammation. Treatment options include topical corticosteroids or circumcision.
Paraphimosis occurs when the foreskin becomes stuck behind the head of the penis and restricts blood flow to the end of the penis. It can result from a medical intervention, such as the use of a catheter. Paraphimosis is a medical emergency. Without treatment, gangrene can result. Treatment aims to reduce the swelling, but most doctors recommend circumcision after recovery, in order to prevent the condition reoccurring.
Balanitis occurs when the head of the penis becomes inflamed or swollen. This may be due to an STI, thrush, skin irritation, or another skin condition. It is uncommon in circumcised males. Circumcision can prevent balanitis reoccurring.
Circumcision and HIV
According to the World Health Organization (WHO), there is “compelling evidence” to suggest that adult circumcision device reduces the risk of contracting HIV during vaginal sex by 60%Trusted Source .
However, they point out that circumcision will offer only partial protection, and they urge people to use barrier methods such as condoms as well.
The higher chance of infection may be because the foreskin becomes more prone to splits and ruptures during intercourse, allowing pathogens to enter the bloodstream.
Another possibility is that the space between the penis and the foreskin might provide an environment in which a virus can survive for a period of time, raising the risk of infection for the individual and their next partner.
Some argue that the U.S. has a relatively high rate of HIV despite high circumcision rates. In addition, the results of studies in Africa and Asia associating circumcision with HIV prevention, mainly in heterosexual populations, may not translate to the U.S.
Risks
Circumcision is a relatively safe procedure, and severe complications are rare.
However, the following risks are possible:- The surgeon cuts the foreskin too short or leaves it too long.
- The wound does not heal properly.
- Blood loss and hemorrhage occur.
- Meatal stenosis occurs. This condition causes the urinary stream to be deflected upward, making it difficult to aim.
- Damage affects the urethra, which is the tube that carries urine through the penis. This can make urination difficult.
- In very rare cases, there may be accidental amputation of the head of the penis.
- Blood infection or poisoning, known as septicemia, may develop.
- The foreskin left behind might reattach to the penis and require further minor surgery.
- There may be a decrease in the sensation of the penis, especially during intercourse.
Complications are more likely Trusted Source when:- an older male undergoes the procedure
- the procedure takes place in unsterile conditions
- inexperienced or untrained providers carry out the procedure
- the procedure takes place in a traditional manner, as a rite of passage
If a qualified medical professional carries out the procedure in a sterile environment, the risks are minimal.

A Guide on Electrical Muscle Stimulation |

Electrical Muscle Stimulation (EMS) has always been a little confusing to performance coaches and sports medicine professionals because the research is cloudy at best. Many of the reasons behind the limitations of science are the ethical boundaries you need to navigate, and the expectations you have with the results of those studies. I recently spent more time working with EMS, as more and more athletes are using EMS devices on their own and we are dealing with the hangover of injuries still lingering in the off-season. What I have learned is that the science is not perfect and there are no best practices.
There has been a resurgence in EMS in sport over the last five years because of Bill Knowles, Derek Hansen, and Henk Kraaijenhof sharing their experiences with athletes. I believe that EMS suit inluding electrostimulation vest has a place in sports performance and the rehabilitation of athletes, but we don’t have a solid explanation of why some athletes don’t respond to it while others seem to come alive from it. In this first piece, I will review some of the current literature on EMS and present a healthy perspective on this modality. (Part 2 will be published as “The Top 6 EMS Protocols for Sports Performance.”)
A Brief History of Electrical Muscle Stimulation in Modern Sport
Without getting into any unnecessary background on electrotherapy (such as a retelling of the way the ancient civilizations used electric fish or citing references to Volta and Galvani), it’s valuable to know how e-stim or EMS has been part of sport in the last few decades. Outside of product design, very little innovation has occurred since the 1950s, making EMS more of an art than a science. Coaches and therapists are sometimes frustrated because transcutaneous electrical nerve stimulation, or TENS for short, gets confused with sports electrostimulation.
To understand the difference between TENS and EMS, you need to know just a little bit about engineering and biology. TENS targets the sensory nerves, while EMS attacks the motor nerve and attempts to recruit as many muscle fibers as possible. TENS is currently used—mainly in vain, in my opinion—to manage pain. In 1965, Ronald Melzack and Patrick Wall proposed the “gate control theory” of pain. What we know about the pain experience is extremely complex and personal, making the TENS intervention for sport very dated and extremely limited for athletes. Some research has shown positive findings, but the modality method of working with athletes in pain is lazy and proven unproductive in clinical research.
EMS focuses mainly on sending current to muscle groups in the hope of eliciting either a recovery response or a performance response later. Based on the current literature, recovery indices appear very limited, and performance benefits have shown up enough with some populations—including athletes—to be accepted as valid complementary treatments. The truth is that our understanding of electrostimulation is usually confined to a few studies on stroke victims and post-surgical wasting, and nothing I have seen has excited me.
What interests me, instead, are the clinicians who have used EMS creatively. Some of the studies on cellular and performance outcomes are strong enough to show that EMS isn’t just a placebo. I have used the Compex systems for nearly 20 years, and have some experience with the Marc Pro, PowerDot, Globus, and ARPwave. If I had to conclude which I think works best, it will be a short answer: All of them work, so choose one based on your needs and not its features.
If you were to go to a medical bookstore and check the physical therapy section on EMS, you would see that it tends to be a set of protocols based on pad placement, current settings, and scheduling sessions. This approach is nowhere near the same as what the modern clinician does and, since we are now entering the bionic athlete era with gait retraining, this only widens the gap between practice and research. It’s easy to shout that you’re ahead of the research, but without evidence, much of what clinicians do becomes like the dated RICE protocol that we still see people clinging to.
A Rapid Review of Electricity for Coaches and Therapists
Electric current can flow in different ways, such as through a wire, or something lesser known, such as a plasma state. The current generated from a muscle electrostimulator uses a conductive pad to transfer through the skin, causing the muscle to contract. The specifics of the muscle contraction will come later, but the important information is that electricity from medical muscle stimulators is more complicated than voltage and ampere. Electricity is not just about whether something is “on” or “off,” and we often take much of the technology we use for granted, especially the safety of the muscle stimulators. Most companies that get involved with e-stim devices are regulated, but it’s up to the consumer to do their homework on the quality of the product.
Experienced coaches and therapists commonly refer to stimulation parameters and share their practices, including the use of different types of settings, such as Russian Stimulation or strength protocols. Stimulation parameters and waveforms can be the subject of their own article but, for the most part, duty cycle, frequency, intensity, and ramp details are part of electrotherapy theory, but are not very well-documented. Regardless of the intimate details, many parallels exist between classic training principles and the current clinical practices of EMS use. Cycles, or waves of energy, are part of a “unified training theory” proposed by several coaches and sport scientists. EMS should be used to improve athletes, similarly to loading the body with training or rehabilitation.
Companies must do their job, not only to prove their machines are delivering exactly what they promise, but also to ensure that their products are used as intended. Most companies have terrible product education, and visiting their YouTube channels makes me cringe more than their highest simulator settings.
The Science of Electrical Contractions With Muscle
Sending electricity through a muscle group sounds like a bad science fiction movie, but that’s precisely what athletes are willing to do to get or feel better. It’s a priority to know what EMS can do physiologically and what is likely ineffective. Five years ago, pioneering researcher Nicola Maffiuletti summarized the differences between a normal muscular contraction and one from electrical stimulation in his NSCA journal article. The two types of contractions have similarities and differences that a coach should know. Overall, EMS is not going to make a major difference. However, like all things in sports training, the little things matter.
One development that throws this concept out the window is the rise in functional electrical muscle stimulation, equipped with electrostimulation shorts, which incorporates active training with the simultaneous overlay of EMS. While we can assume that the merging of both contractions will yield a hybrid result, most of the research is with disease models and only clinical rehabilitation has shown merit with this in early post-operation subjects. I have yet to see a single study with elite athletes performing EMS in conjunction with conventional training, but the case reports and work with spinal cord injury patients is promising.
Finally, EMS is used to help with neuromuscular adaptations and, while sessions may prevent atrophy, the improvements are from neural drive-like mechanisms, not from increased protein synthesis rates. EMS doesn’t directly create hypertrophy changes to the muscle, and a study on nutrition and e-stim showed no acute changes.
What is also important to know is that electrically stimulated muscles are, for the most part, superficial, and that is useful for propulsive muscle groups. Some rogue therapists are using fine needle EMS with low current for deeper muscle penetration for rehabilitation purposes. Most EMS experiences are one muscle at a time, but some athletes are getting simultaneous total body sessions. Nobody knows if total bodywork is more time-efficient or if a possible synergistic benefit exists, but down the road, studies will likely discover if there is a value beyond convenience.
The Scientific Benefits of Stimulating the Neuromuscular System
If you were to read a catalog of features and settings for a personal e-stim device, the list would be very long, ranging from relaxation massage all the way to explosive strength. While, technically, different settings will have unique stimulation protocols from the device programming in the electrostimulation center, the reality is that only three purposes exist with EMS and the research is enough to form a realistic expectation. The three EMS benefits are strength training, rehabilitation, and a little regeneration. Distilling the benefits more, you can make an argument that EMS helps with general muscle strength and facilitates low-level recovery for travel. That’s about it, but it’s enough to warrant investing in it, especially when sport moves into the unfortunate health compromise for winning.
Sports Performance
EMS and strength, and the results that may lead to jump and sprint performance, are mixed in the research. However, enough research shows that if EMS is done with specific protocols, a positive result is possible, especially with the less-trained athlete. So far, much of the work has been done with soccer, and some recent investigations of youth jumping performance and plyometrics had favorable outcomes.

PVP-Polyvinylpyrrolidone is a nonionic water-soluble polymer and can be applied in a variety of fields-of-use owing to following advantageous characteristics.
1. Good solubility in water as well as various organic solvents
2. Good affinity to various polymers and resins
3. High hygroscopicity
4. Good film formation property
5. Good adhesiveness to various substrates
6. Good chelate / complex formation property
Polyvinylpyrrolidone (PVP) is a water-soluble polymer obtained by polymerization of monomer N-vinylpyrrolidone. PVP is an inert, non-toxic, temperature-resistant, pH-stable, biocompatible, biodegradable polymer that helps to encapsulate and cater both hydrophilic and lipophilic drugs. These advantages enable PVP versatile excipients in the formulation development of broad conventional to novel controlled delivery systems. PVP has tunable properties and can be used as a brace component for gene delivery, orthopedic implants, and tissue engineering applications. Based on different molecular weights and modified forms, PVP can lead to exceptional beneficial features with varying chemical properties. Graft copolymerization and other techniques assist PVP to conjugate with poorly soluble drugs that can inflate bioavailability and even introduces the desired swelling tract for their control or sustained release. The present review provides chemistry, mechanical, physicochemical properties, evaluation parameters, dewy preparation methods of PVP derivatives intended for designing conventional to controlled systems for drug, gene, and cosmetic delivery. The past and growing interest in PVP establishes it as a promising polymer to enhance the trait and performance of current generation pharmaceutical dosage forms. Furthermore, the scrutiny explores existing patents, marketed products, new and futuristic approaches of PVP that have been identified and scope for future development, characterization, and its use. The exploration spotlights the importance and role of PVP in the design of Povidone-iodine (PVP–I) and clinical trials to assess therapeutic efficacy against the COVID-19 in the current pandemic scenario.
PVPP is a synthetic, high-molecular-weight clarifying agent made up of cross-linked monomer of polyvinylpyrrolidone. PVPP has long been used in the beverage industry as a polyphenol adsorbent. Although, it has been called as a “protein-like” fining agent, insoluble PVPP interacts with only few reactive groups. Hence, PVPP is used for binding and removing smaller phenolic compounds such as catechins and anthocyanins, which are responsible for causing browning and bitterness in wines. However, PVPP, along with charcoal and casein, can remove resveratrol, a component that imparts certain health benefits.
Polyvinylpyrrolidone (PVP) is a linear polymer of 1-vinyl-2-pyrrolidone monomers used as a binder, emulsion stabilizer, film former, hair fixative, and suspending agent-nonsurfactant. The molecular weight of the polymer ranges from 10,000 to 700,000. PVP K-30, with an average molecular weight of 40,000, is typically used in cosmetic formulations. The highest concentration reported to be used is 35%. There was no significant absorption of PVP K-30 given orally to rats, and the acute oral LD50 was >100 g/kg for rats and guinea pigs. Neither toxic effects nor gross lesions were found in rats maintained for two years on a diet containing 10% PVP K-30. Short-term PVP inhalation studies produced mild lymphoid hyperplasia and fibroplasia in rats, but no inflammatory response. In animal studies, no evidence of significant ocular irritation, skin irritation, or skin sensitization was found at PVP-iodine solution concentrations of 10%. While PVP-iodine is not a cosmetic ingredient, these negative findings were considered to support the safety of the PVP component. Undiluted PVP K-30 was not a dermal irritant or sensitizer in clinical tests. No developmental toxicity was seen in vehicle controls where PVP was used as a vehicle for another agent. In certain assay systems, PVP was genotoxic, but was negative in the majority of studies. Orally administered PVP significantly decreased the rate of bladder tumors in mice exposed to bracken fern. Several studies tested the carcinogenicity of subcutaneous implants of particulate PVP in rats, mice, and rabbits. Although the majority of these studies conducted in rats were positive, tumors (sarcomas) were localized to the site of implantation. Based on the available data, it was concluded that PVP is safe as used in cosmetics.

Power Banks – What Impact They Have On Your Phone's Battery |
Posted by: qqjoso89a - 08-31-2021, 06:31 AM - Forum: Welcomes and Introductions

Anyone who has a very busy schedule will tell you that a power bank is their lifesaver. A power bank is essentially a portable charger. Power banks are most commonly used to charge cell phones but are often also used to charge laptops, speakers, and various other chargeable devices.
In this age, our cellphones contain our entire lives in it, be it a photographer’s photographs, to an entrepreneur’s documents. When you are on the go at most times, it’s virtually impossible to find wall outlets everywhere to charge your phone if the battery drains. A conventional power bank prevents you from running into a crisis when your phone suddenly turns off when you need it the most.
Keep on reading further for more about power banks, and what impact they have on your phone’s battery.
Types Of Power Banks:
Most of the power banks available in the market consist of two types. One consists of Lithium-ions cells, while the other contains Lithium-Polymer cells.
Lithium-ion cell power banks have a higher energy density and are cheaper than the other. However, power banks containing Lithium-ion cells lose their charging capacity over the duration they are used and are bulkier.
On the other hand, power banks with Lithium-Polymer are expensive, but they are safer, and unlike Lithium-ion, they don’t lose their actual charging capacity with time. They also take less time to charge.
Further, they are divided into three broad categories:
- Universal Power Bank
The most common ones, universal power banks come in various sizes and output variations and give the end consumer a wide range to choose the best one according to their requirements.
- Solar Charged Power Bank
These solar power bank with cable contains photovoltaic panels which are charged through sunlight. This is then converted and used to charge electronic devices.
Although it’s an environmentally friendly device, it tends to take a lot of time to charge, and that too is limited to availability of enough sunlight.
- Battery Phone Case
These are compact and easiest to carry along. However, they have a very low variety available in term of devices.
So the next time you are considering buying a power bank, choose one based on the type which is more suitable for your requirements.
How To Choose The Best Power Bank For Your Phone:
There are some factors to consider before buying a power bank with dale cable, include:
The capacity a power bank should always be more than the capacity your phone requires. For example, a 2200 mAh wouldn’t be able to fully charge a phone with a requirement of 3000 mAh. Likewise, a power bank with 6000 mAh would be able to charge your phone fully two times. Also, there are wireless fast charging power banks.
Some power banks have 1 output outlet; some have 2, and so on. Choosing one depends on how many devices you would need to charge at the same time.
How much output your phone needs should also synchronize with the output the power bank gives out. Ideally, the standard output should be 5V for phones. Any more, and it would damage the phone.
Advantages Of A Power Bank:
The main benefit of power bank is that they are great for charging phones on the go, or when there is no electricity available.
Aside from that, most power banks come with a large capacity, which makes them handy for charging your phone multiple times, without recharging it. And when the battery of the power bank does drain, they can be easily charged through laptops, car chargers, and wall sockets, whichever is more convenient.
Disadvantages Of A Power Bank:
Power banks come with their own share of disadvantages as well. Many of the power banks available are either bulky or expensive. Apart from that, they do require to be charged when their battery drains, and if their capacity is lower, then they drain faster.
They also impact the battery of a phone in some instances, as mentioned below.
Impact On Battery:
While it’s extremely rare for a power bank to damage the battery of a phone, there are some instances where it might happen. Here are some cases where you might be damaging your phone’s battery with your power bank, and how to fix them:
- You Are Using A Bad Quality Power Bank
Quality is very important when choosing a power bank. A bad quality power bank can damage your phone’s battery, as well as your phone’s charging port. It can also create some security risks. For example, overcharging a bad quality Lithium-ion power bank can cause the power bank to explode.
- Your Power Bank Has The Wrong Voltage
Having the wrong voltage in your power bank will lead to problems. The ideal voltage to charge a phone is 5V. If any power bank gives a voltage of 4.2V or less, it will drain your battery instead of charging it.
Any voltage output greater than 5V will extensively damage your phone’s circuits by overloading it more than it can handle.
- You Are Overcharging:
Power banks should essentially be used sparingly. Using power banks to constantly keep your phone at 100% charge will over time damage the battery, which will lead to your phone not being able to retain its charge for long.
To avoid these problems, avoid using your power bank to overcharge your phone. Use it for emergencies, and even when you do use it avoid charging your phone up to 100%.
Along with that, buy your power banks from authorized retailers, and choose the highest quality of power bank, such as PD fast charging power bank, with the right requirements for your phone. Dealna.com has a wide variety of authentic, high-quality power banks:

With the accelerated pace of human life, disposable tableware has gradually entered the fast food business. Since the first use of disposable tableware in China in 1984, foamed plastic tableware with polystyrene (eps) as the main raw material has spread all over the country and entered people's daily life, forming a huge consumer market. According to statistics, at present, China consumes about 10 billion fast food appliances each year, most of which are disposable foam plastic tableware, and grow at a rate of 25% per year.
Due to the non-degradable nature of polystyrene, it is difficult to recycle and other disadvantages, which brings great inconvenience to the processing work.
Currently in the streets and alleys of China's cities, tourist attractions, railways along the rivers and lakes. This kind of discarded disposable tableware can be seen everywhere, which is shocking and causes serious pollution to the environment. This kind of "white pollution" not only increases the labor intensity of sanitation workers, but also brings visual pollution to people. It is increasingly polluting the land resources and water resources that we depend on, and it also brings a lot of people. Inconvenience and harm.
It is gratifying that China has done a lot of work in this area and has achieved great results. With the scientific guidance and strong support of the government, various environmental tableware has emerged. To good social effects.
The disposable corn starch tableware produced by Hengfeng is a healthy and environmentally friendly tableware, as sugarcane tableware. The corn starch tableware is a biodegradable product. It is made from corn starch as the main raw material and processed by high-tech production process. The natural conditions can be degraded by itself, avoiding the environment. Pollution, saving non-renewable resources such as oil, has been tested by the national authoritative testing department, and all sanitary and physical and chemical indicators have reached national standards. It is an ideal substitute for the “disinfected tableware” that is widely used in the catering market.
Cornstarch tableware is a biodegradable product. It uses corn starch as the main raw material and is processed through high-tech production technology. It can be degraded by itself under natural conditions, avoiding environmental pollution and saving non-renewable resources such as petroleum. According to the inspection by the national authoritative inspection department, all the physical and chemical indicators of hygiene have reached the national standards, and it is an ideal substitute for the disinfection tableware commonly used in the catering market. Corn starch and biodegradable tableware are pollution-free green products for human survival and environmental protection.
Corn starch is made from the polymerization of grape molecules and is the more common storage form of carbohydrates in cells. In addition to food, it is industrially used for the manufacture of dextrin, maltose, glucose, alcohol, etc. It can also be used for conditioning flower pulp, textile sizing, paper sizing, and pharmaceutical tablet compression.
The general formula of corn starch is C6H10O5, and maltose is hydrolyzed to the disaccharide stage. The chemical formula is C12H22O11. After complete hydrolysis, glucose is obtained. The chemical formula is C6H12O6. It is divided into two types: amylose and amylopectin. Blue, amylopectin turns purple when it meets iodine.
Advantages of disposable degradable tableware, such as sugarcane bowl and sugarcane cup:
Pollution-free, because it is refined from corn starch and other environmentally friendly materials, it does not contain any harmful substances to the human body, so it can be used for a long time with confidence.
Zero pollution, the product is buried in the soil, and at a suitable temperature, it can degrade to form carbon dioxide and water after 90 days, without causing pollution to the soil and air.

We need a variety of boxes when we’re relocating for ease of transportation and protection of our belongings. These moving boxes are meant to be temporary and are commonly made from cardboard.
Cardboard moving boxes should be used for their primary objective – moving. But it’s not unusual to store items long term in these inexpensive boxes. The misconception stems from the idea: pack it once, decide if you need the item right away, and if not, put the box in storage, wherever that might be – garage, attic, basement, shed, or off-site storage.
Sometimes it’s better to take the time to unpack all your items after a move, then carefully store each item properly depending on where it will end up. We’ll go through scenarios when cardboard boxes aren’t ideal for long-term storage and even show you how to store cardboard boxes the right way.
Long Term Storage Cons for Cardboard Boxes
In order to store cardboard boxes effectively, it’s important to know all the problems associated with cardboard. - Cardboard breaks down much more quickly than plastic and is more susceptible to weather conditions, such as heat and humidity.
- Cardboard takes a shorter amount of time to age. If you use cardboard boxes to store items long term, don’t expect the items to remain in perfect condition.
- Bugs are especially attracted to cardboard boxes and their contents.
Some storage areas are worse than others for cardboard. Be aware of what is being stored and where before you decide to use a cardboard box. Are you storing on a concrete slab or other outdoor flooring in a shed? These moist areas can be disastrous for cardboard boxes.
Concrete slabs and outdoor flooring, if not sealed properly, will seep moisture, and if you have cardboard storage bins on the ground, it will then absorb the moisture and get the items in the box wet. If this happens, your items will become ruined and mildew or mold will start growing in the box.
If you have chosen to stack cardboard boxes in this situation, the bottom box walls have now become compromised, and there is a chance of the stack falling.
How to Store Cardboard Boxes Properly
1. Maintain Your Storage Area
If you maintain your storage area, cardboard boxes can last a lot longer. Keep boxes on shelves so they are always off the ground, don’t stack more than a few boxes high, and make sure the heavy items are on the bottom of the stack.
2. Use Climate Control Storage
Another thing that really helps keep your cardboard boxes in good condition for storage is a climate-controlled environment. If you have the option of climate-controlled and non-climate-controlled, and you plan on storing items in cardboard boxes, always take the climate-controlled option. What this does is maintain the level of humidity and temperature so your cardboard boxes will not be as affected by outside conditions.
3. Opt for Indoor Storage Space Like an Attic
Instead of storing your items in the garage, perhaps you decide to store them in your attic with a wooden floor. There is no chance of moisture seeping up through the floor to ruin the boxes. However, be aware that there is a chance of water leaking through the roof and onto the boxes, thus causing the same type of damage as in the garage.
When to Use Plastic Bags for Storage
Sometimes it’s easier to err on the side of caution. As long as they are sealed correctly, plastic boxes and totes are not affected by moisture or water. They are also not as susceptible to breaking down when stacked. These storage options are better at dealing with the elements and are much better protected from insect infestation.
Plastic boxes come in a variety of colors. One benefit to these containers is the additional organization offered. Store items in clear boxes with different colored lids to create an organizational system for your belongings in storage. You can use color coordinating lids with the subjects of what you are storing. You can even make a legend of the colors and stick it to the wall of the storage area.
Some examples of lid color coordinating are:- Green – Christmas, winter
- Red – Valentine’s Day
- Orange – Halloween, Thanksgiving, fall
- Blue – Fourth of July, summer
- Pink – Easter, spring
- Black – New Year’s
Storage boxes come in various sizes, and you don’t need tape to put them together. They usually have locking lids, and best of all, the clear ones can help you see what you are storing – a great start to helping you get or stay organized.
When determining what long term storage box to use, make sure you consider the conditions of your storage area. Sometimes you can get away with cardboard boxes, and other times it’s best to stick with sealed plastic totes. Not sure where to source quality cardboard boxes? Visit any of our Life Storage locations for moving boxes in a variety of sizes.

2. How Does A Toggle Clamp Work?
Known to be the quick-action hold down tool, a toggle clamp is employed to keep a workpiece stationary. It may be fixed to a fixture or a bench. Or it may be handheld for holding different pieces of wood together.
A toggle clamp operates thru a system of pivots and levers. The clamp actuation moves against the workpiece. Then, it stretches or compresses the linkages. It locks Y moving the center pivot past the centerline of other pivots. It firmly holds the workpiece until you move the handle for a successful release.
Different Types of Toggle Clamps
As with other tools at home or workplace, a toggle clamp has various types. Keep reading to find more information.
Horizontal Toggle Clamp
When the handle is in the horizontal position, this toggle clamp is in the locked position. As the handle moves towards the table, its securing arm locks into place. Commonly, this is used when there are height limitations to machinery. Plus, don’t forget to mount it to a table.
Vertical Toggle Clamp
The vertical toggle handle with red handle stands straight when locked. It is designed with various holding capacities. It can apply a considerable amount of pressure. Every time you pull the handle away from the tool, you can lift the securing bar and place an object under the bar. As the handle moves into vertical alignment, the pressure is applied. Not only is it safe for a worktable, but it also used to secure wood around machinery.
Push-Pull Toggle Clamp
The handle of this clamp moves the securing bar in a straight line. Once the handle is engaged, the securing arm pushes into an object, locks, and holds it in place. Generally, you can lock the clamp in two positions. They are also suited for clamping different objects together, such as pieces of wood and molds.
The push-pull clamp has a superb plunger that travels in and out. As the name suggests, the clamp offers push and pull offers. It may lock in either the pull or push position. It may also be referred to as a straight line or plunger-style clamp.
Pull-Action Latching Toggle Clamp
This clamp works similar to the latch on fishing tackle boxes. Its handle is appropriately aligned with the opposing latch. Then, it is pulled back down into the locking position. This is used for closing objects such as mold closures and latching doors. Ask the manufacturer of your choice to help you have a brilliant decision in no time.
Categorized into two types such as U-hook and J-hook, pull action latching toggle clamp is ideal for sealing lids and molds. With its threated adjustments, it becomes adaptable to many applications. Options include stainless steel, carbon, and rubber material.

With the right and effective toggle, it can make a welding project much easier than you think. It can help you construct a welding fixture, improve quality, and reduce production time.
As a piece of equipment, a welding jig has several parts. Not only does this form a weldment, but it also keeps a fixed dimensional relationship among various parts. A welding fixture needs to fulfill the requirements from being well-designed in light of durability, a great conductor of electricity, and enough tolerance to take care of deviations of steel castings.
Electronic Test Fixtures
An electronic test fixture is a tool for testing devices. In assessing electronics such as chips and circuit boards, this equipment can hold the device. But this depends on the quality of your option. Choose the solution that does not require extensive maintenance. Also, consider efficient working, easy to operate, and functional solutions on the market.
Injection Molding
A toggle clamp is also applied in injection molding. Its primary function is to open or close the mold. Toggle clamp uses mechanical linkages to produce higher forces. Aside from that, direct hydraulic clamp is utilized.
Conveyors
Known as mechanical devices, conveyors are used to moving packages or other items without much effort. More particularly, they are employed to move bulk materials such as aggregate and gravel. They have frames that support wheels, rollers, and belts. They consist of belt conveyors for moving belts, vertical conveyors for lifting materials, and overhead conveyors for hanging items during transportation. They also have a toggle clamp to improve the level of comfort and productivity.
Milling, Drilling, Bonding, and Sealing
Homeowners and contractors encounter a hard time when milling, drilling, bonding, and sealing. With several tools to opt, a toggle clamp should not be ignored. It makes the tasks simpler than you expect. You can put an end to the hassles of doing all drilling or sealing projects.
Machine Tool Positioners
Toggle clamps also serve as machine tool positioners. Right positioning of machines cannot be done manually. It requires the use of a toggle clamp to make the process accurate and error-free. Whether your existing toggles are not efficient and tested, rely on a company with a strong reputation in the business. Whatever your situation, a clamp from a reliable provider is an excellent choice.

These fixtures are a support or work-holding device in the production history. They are used to locate or even support the work, guaranteeing all parts to maintain interchangeability and conformity. Using these tools improves the economy of manufacturing. The application of toggle clamp in production fixtures make the equipment useful. It provides a boost in worker’s performance and productivity.
Inspection and Gaging Fixtures
Controlling a process is crucial in manufacturing parts and assemblies. Inspection and gaging fixtures can play an essential role in effective manufacturing. These give machine operators the opportunity to ensure that every piece is produced as accurate as possible. But, without a toggle that works well, the system and process are greatly affected. So, eliminate inefficient clamp in your list and buy the one that’s of high-quality.
Coping with Narrow Rails
Door rails in furniture are risky to pass by a coping bit. Without enough support, the rail may turn into a disaster. Not only will the cut be damaged, but your fingers are also at risk. But all of these safety issues can be avoided with the use of toggle clamp. Integrating toggles into your routine makes your workplace a damage-free environment. You can use a toggle clamp to construct a coping jig. All materials needed are a thick base piece and a spacer board. Top the piece with a board. This will serve as a sacrificial surface that allows the jig to slide and help you create perfect cuts.
Cutting Tenons with a Table Saw
Standing the workpiece on its end and feeding it freehand with the blade are unsafe. It’s better to create a tenoning jig using two toggle clamps. You can build a fence to stand the workpieces without a hassle. Also, don’t forget to mount the clamps to a spacer. You can now feed a block of wood perfectly thru the saw. You can adjust the rip fence for cheek cuts.
Locking Down Miter Joints
Closing miter joints with a bar-style clamp are not as safe as you think. It’s brilliant to choose toggle clamp. Thanks to its well-designed and awesome features. You can use it with a square back-up block and base form. Utilize painter’s tape to prevent the glue from sticking to the backup block and base.
Tension-free Tapering
Typically, the two-leg tenoning jigs have a significant flaw. There is no a comfortable and effective way to hold a workpiece against the angled leg of the jig. From employing a push stick to holding it with your hands is awkward and risky. With toggle clamp, you can experience convenience throughout the process. More particularly, you can keep your fingers away from danger. You can make a tapering jig from a piece of scrap without a burden.
All you have to do is align the layout line on your leg workpiece and screw spacer blocks to hold it at the right angle. Screw the toggles to the spacers. After clamping your workpiece in place, you can now set the jig against the rip fence of your saw. Then, adjust the fence to make sure that the jig edge is flush against the saw blade properly.
Feeding the jig past your blade will cut the tapered waist with error-free precision. You don’t have to employ a push stick to hold the leg steadily. Aside from that, your fingers are away from the blade. Lastly, don’t forget to unscrew and reposition your spacer locks to best fit your new taper angle.
Template-Routing Narrow Workpieces
Both a piloted bit and a template are helpful for you to turn out arched door rails and other shaped parts. However, routing curved and narrow workpieces can place your fingers close to the bit. So, why risk your hand? There’s an excellent way to ensure your safety. Make your template piece wider than normal and add a spacer block for your toggles. Next, position the spacer to extend the workpiece for proper trimming. Fasten your toggle to the spacer to press the workpiece against your template easily.With a toggle clamp, you can say bye to double-sided tape, push pads or messy hot-melt glue. You can still hold the parts in alignment by locking the clamps. By that, everything is set for routing. While working at home or in the office, you can use a toggle clamps as hand-holds.
Other Applications
Toggle clamp is also used in a door closure, assembly, and woodworking jigs, and latches for container lids. Without its integration into these applications, related tasks will be difficult. While spending most of your time, the result is now what you expect in the first place. Thanks to toggles. Doing these jobs become fast.

How Diesel Engines Work
Ever wonder what the difference is between a gasoline engine and a diesel engine? Diesels are more efficient and cheaper to run than gasoline engines. Instead of using carburetion or port fuel injection, diesel engines use direct fuel injection. Find out what else makes diesel engines different!
How Hemi Engines Work
The HEMI engine has an awesome design and great performance, and it's pretty unique in operation. With the revitalization of the HEMI in the 2003 Dodge trucks, industry and consumer attention is once again on this interesting configuration. Check out how the HEMI works and see what makes it different from the typical engine design.
How Rotary Engines Work
A rotary engine is an internal combustion engine, but it's not like the one in most cars. Also called a Wankel engine, this type of engine performs intake, compression, combustion and exhaust in a different part of the housing. Learn about the unique rotary setup and how it compares performance-wise to a piston engine.
How Radial Engines Work
Radial engines reached their zenith during WWII. But today they are not that common. One place where you can still see the radial engine's influence is in the two-cylinder engine of a Harley-Davidson motorcycle. This remarkable engine can be thought of, in a way, as two pistons from a radial engine. Find out about radial engines.
How Quasiturbine Engines Work
The quasiturbine engine takes the Wankel concept and improves on it: Instead of three combustion chambers, it has four, and the setup of a quasiturbine allows for continual combustion. That means greater efficiency than any other engine in its class. Learn about the quasiturbine and why it might be the most promising internal combustion engine yet.
How Camshafts Work
The camshaft has a huge effect on engine performance. It helps let the air/fuel mixture into the engine and get the exhaust out. Learn all about the camshaft and how a new one can radically change an engine's behavior.
How Superchargers Work
Since the invention of the internal combustion engine, automotive engineers, speed junkies and race car designers have been searching for ways to boost its power. One way is by installing a supercharger, which forces more air into the combustion chamber. Learn how superchargers can make an engine more efficient.
How Turbochargers Work
When people talk about race cars, or high-performance sports cars, the topic of turbochargers almost always comes up. Turbochargers use some very cool technology to make an engine more powerful, but the concept is really quite simple. Find out how turbos increase the speed.
How Fuel Injection Systems Work
The last carburetor-equipped car came off the assembly line in 1990. Since then, fuel injectors have been the primary means of getting gasoline into the engine cylinder so it can combust and you can drive. Find out how fuel-injection systems work.
Power Train
How Manual Transmissions Work
If you drive a stick-shift car, then you may have a few questions floating around in your head. Have you ever wondered, "What would happen if I were to accidentally shift into reverse while I am speeding down the freeway? Would the entire transmission explode?" Find out all about manual transmissions.
How Automatic Transmissions Work
Automatic transmissions take the work out of shifting. A truly amazing mechanical system, the automatic transmission in a car accomplishes everything a manual transmission does, but it does it with one set of gears. Learn how the whole setup works.
How Clutches Work
You probably know that any car with a manual transmission has a clutch -- it connects and disconnects the engine and transmission. But did you know that automatics have clutches, too? Learn how the clutch in your car works, and find out about some interesting and perhaps surprising places where clutches can be found.
How CVTs Work
In a regular transmission, the gears are literal gears -- interlocking, toothed wheels. Continuously variable transmissions, on the other hand, don't have interlocking gears. The most common type operates on a pulley system. Learn all about the smooth-operating, ultra-efficient CVT.
How Differentials Work
Without a differential, the driven wheels (front wheels on a front-wheel drive car or rear wheels on a rear-wheel drive car) would have to be locked together, forced to spin at the same speed. Find out how this essential component allows the wheels to rotate at different speeds.
Braking System
How Brakes Work
A car's brakes are probably the most critical system on the vehicle -- if they go out, you have a major problem. Thanks to leverage, such as AUDI VW headlight level sensor, hydraulics and friction, braking systems provide incredible stopping power. Find out what happens after you push the brake pedal.
How Disc Brakes Work
Disc brakes are the most common brakes found on a car's front wheels, and they're often on all four. This is the part of the brake system that does the actual work of stopping the car. Find out all about disc brakes -- even when to replace the pads.
How Anti-lock Brakes Work
Stopping a car in a hurry on a slippery road can be challenging at best and at worst, very, very scary. Anti-lock braking systems (ABS) help alleviate the danger. Learn how anti-lock brakes prevent skidding, check out what that sputtering is and find out how effective they really are.
How Power Brakes Work
Power brakes are fairly ingenious machines -- they let you stop a car with a simple twitch of your foot. The concept at the heart of the power braking system is force multiplication -- a whole lot of force multiplication. Get inside the black cannister that provides the power.
How Master Cylinders and Combination Valves Work
We all know that pushing down on the brake pedal slows a car to a stop. We depend on that every day when we drive. But how does this happen? The master cylinder provides the pressure that engages your car brakes. Learn how the master cylinder works with the combination valve to make sure you can brake safely.
Steering, Suspension and Tires
How Steering Works
When it comes to crucial automotive systems, steering is right up there with the engine and the brakes. Power steering systems make the job a whole lot easier, and the internal workings are pretty cool. What happens when you turn your car is not as simple as you might think. Find out all about car steering systems.
How Car Suspensions Work
All of the power generated by a car engine is useless if the driver can't control the car. The job of a car suspension is enormous: maximize the friction between the tires and the road surface, provide steering stability and ensure the comfort of the passengers. Learn how car suspensions work and where the design is headed in the future.
How Tires Work
In the market for new set of tires? All of the different tire specifications and confusing jargon the tire sales clerks or "experts" are shouting at you making your head feel like a tire spinning out of control? Find out all about car tires, including what those sidewall symbols mean!
How Self-inflating Tires Work
Self-inflating tires perform two crucial functions: They automatically maintain ideal tire pressure for safety and performance in standard conditions, and they allow the driver to alter psi on the fly to adjust to changing terrain. Learn how self-inflating systems like the Hummer's CTIS work.
How Sequential Gearboxes Work
Combine the ease of an automatic with the driver control of a manual, such as a window switch, and what you've got is a sequential manual transmission. Instead of having to navigate an H pattern, a simple forward push advances the gear. It's the transmission used by race cars and an increasing number of high-performance street cars.

What is a Precision Lathe? |

Sometimes a shop doesn’t do enough turning work to justify the purchase of a CNC lathe. But when it needs to produce precision turned parts, even if for a very small lot size, the shop needs a solution.
Such was the case for Sturges DesignWorks, a company in Portland, Ore., that provides automation and design engineering solutions in a variety of industries, including medical products, electronics, fixturing and tooling, and research and development. The company was working with a client who needed a special machine built that required substantial CNC lathe work. But Sturges didn’t have a lathe. “CNC lathes are expensive, take up much needed floor space, and have a steep learning curve,” explains Dan Sturges, company CEO. He considered a CNC mini lathe, but found that it would not be precise, rigid or accurate enough for the work required.
To address the issue, the company developed what it calls the Sturges Turning Head system to bridge the gap between traditional, full-featured CNC lathes and low-productivity, small CNC mini lathes. “I had always wondered why we couldn’t somehow do precision CNC lathe work on a CNC milling machine,” Mr. Sturges says. “The problem is, even if you attach a lathe tool to the mill spindle and lock it, there’s still a tiny bit of play that makes it impossible to maintain a standard of precision. So we developed a turning bar toolholder that places the tip of the tool at the spindle’s center of rotation, eliminating the slight play in the tool tip and providing the precision and accuracy needed for professional, high-quality swis type automatic lathe work on a mill.” Based on this principle, the company built the prototype for the Turning Head system, which is capable of external turning, facing and contouring operations. An optional cross slide accessory bolts onto the table, allowing for plunge operations such as parting and grooving.
The Turning Head spindle—the equivalent of a lathe headstock—is made of steel and cast iron and uses premier Grade 7 pre-loaded ball bearings that are lubricated for life. The standard model has less than 50 millionths of an inch runout, and the super-precision model has less than 20 millionths. It has a large, through-bore 5C spindle with a 4-degree taper mount nose.
The system comes with a set of three turning bars, each with an R8 or 3/4-inch straight. The universal design allows left-hand, right-hand and center cutting operations simply by rotating the tool. Tool changes between different turning operations are eliminated. The toolholders are available in three sizes (1/32 radius, 1/64 radius and 1/128 radius) and maintain cutter concentricity to less than 0.001-inch TIR.
Operating the system is straightforward. The operator places a piece of stock in the spindle, tightens the collet, turns on the unit, and hits “Go” on the CNC interface. The system allows the machinist to set up a job on a mill and crank out smooth, accurate parts in a repetitive way. Operating on the existing milling machine’s software, the CNC program provides fast, efficient operation without the need to learn new software.
It’s hard to justify the expense of a multi-axis precision CNC lathe when only one, ten or 100 parts are required. “Machinists, engineering departments, automation groups, tool makers, mold makers and machine builders often don’t have the need for high-volume production,” Mr. Sturges says. “What they need is an economical way to create precision lathe parts.”
The Turning Head system can fill that void. Indexing capability allows indexing the work and seamlessly transitions between milling and turning operations on the same part in the same setup. Multi-axis capability is achieved on an existing machine in the shop. According to Mr. Sturges, “Parts made with this system are indistinguishable from parts made on a swiss CNC machine—same accuracy, same repeatability, same quality.” In a sense, it’s the best of both worlds.
A precision swis lathe is a computerized lathe used to create detailed solid objects from a single piece of wood or metal. Using a sophisticated computer software, the precision swis turning lathe can produce a near-finished product with minimal waste. A lathe functions by spinning the raw materials while cutting, drilling, sanding, knurling or deforming. The use of a lathe produces a finished product that is symmetrical along the axis of rotation.
Earlier versions of a lathe have been traced back to the Egyptians, who developed a two person lathe using a manual process. This design was improved by the Romans who added a turning bow to provide a more consistent turning rate. In the Middle Ages the pedal was added to allow the craftsman to use both hands to work on the wood. This type of lathe is called a spring pole lathe and the development was critical to expanding the types of items that could be created on a lathe. A great lathe was the first lathe to allow the piece to turn continuously but was powered by one person turning a crank while the other worked on the piece.
Only during the early 19th century was a motorized lathe developed. This change significantly reduced the time needed to complete an item and allowed the addition of metal in the process. The addition of computers in the early 1970s created precision lathes that are used today for the mass production of high quality product. This shift has removed the need for master craftsman and replaced these roles with computer operating technicians.
A precision lathe, such as single spindle automatic lathe, is able to cut and shape a material to within 0.001 inches (0.00254 cm) of accuracy. The cylindrical basis of the lathe means that the material is secured at each end and the product is created by the removal of materials from the solid item. A precision lathe is used to create baseball bats, table legs, poles and a wide range of ornamental pieces.
In order to work with a precision lathe, you will need to be trained on the specific equipment used. The original design of the product is completed by a product design and the actual programming is done by the lathe operator. Repeated testing is completed before the mass production work is started. The modern lathe is a highly complex machine that can product thousands of items an hour.
When purchasing a precision lathe, it is important to review the detailed product specifications. Make sure it will have the capability of creating the types of products that you require. Check the details of the warranty and service agreement to ensure that your investment is properly covered.
