Welding is the joining of metals by applying heat, sometimes with pressure and sometimes with an intermediate or filler metal having a high melting point. The intermediate or filler metal that is used to join metals together is commonly referred to as a welding rod. Many welders use welding rods containing a high percentage of the element manganese.

Given what we know about the toxic, even fatal, effects of silica exposure in the workplace, it is more vital than ever for employers to comply with local, state, and federal laws governing silica exposure. The crystalline toxin, which causes such fatal diseases as silicosis, pneumonia and even tuberculosis, is extremely dangerous - but with the proper safety measures, silicosis and other occupational diseases related to silica exposure are entirely preventable.

They may seem like mere numbers, but statistics and demographics information can give important information on who is affected by traumatic brain injury (TBI) - and possibly shed light on how to prevent brain damage. This article takes a closer look at who is impacted by TBI in an attempt to show the true costs of brain damage to victims, their families, and society at large.

Since their invention in the 1950s, up through development during the 1970s and finally institution as a required feature in the 1980s, airbags have become an important factor in decreasing injuries of those involved in automotive accidents.

Airbags function as supplemental safety devices designed to work with seat belts to minimize injuries in vehicle accidents.

With the ever-increasing number of motor vehicles on the roads today, it is no surprise to find that car, motorcycle and truck accidents are a leading cause of personal injury. It has often been said that individuals are more at risk for becoming injured while driving rather than flying, and as their are more individuals on the road each year, this appears to quickly becoming the dangerous truth.

Seat belts have the ability to better protect vehicle occupants from fatal accidents than anything else. According to federal statistics, in 2003, the use of seat belts saved nearly 15,000 lives nationwide. However, even more than 6,000 deaths per year are related to the improper use -- or the failure to use -- the proper seat belt restraints during a car crash.

An article published in the Journal of Translational Medicine in May 2008, brought to light research that is being conducted by several Italian scientists, which exposes the possibility of treatment for mesothelioma cancer with nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs, NSAIDs, are anti-inflammatory and analgesic drugs often found in small doses in common pain relieving over-the-counter drugs such as aspirin.

Each year in America, there are millions of traumatic brain injuries (TBIs) that severely debilitate citizens from a number of common, everyday activities that often depend on the severity of their injury.

According to the National Institute of Neurological Disorders and Stroke (NINDS), common TBI disabilities include difficulties with cognition affecting memory and reasoning; communication through expression and understanding; sensory processing, affecting the five senses in various combinations and ways; behavior and mental health problems ranging from personality changes to increased aggression to social inappropriateness; and TBI can also cause an individual to become unresponsive and even fall into a coma.

Although the sports medicine community has not come to a consensus, there are two methods of objective testing that may satisfy the reasonableness test: neuropsychological testing and postural stability testing.

Neuropsychological testing measures the athlete's cognitive flexibility, attention span, orientation, concentration, visual-spatial capacity, distractibility, immediate memory recall, and problem-solving abilities.

Buses generally thought to be a safe method of travel; after all, they are significantly larger than other vehicles on the road and many buses do not even come equipped with seat belts.

A study by the National Bus Safety Council between the years 1987 and 1996 found 4.3 bus rider fatalities per year compared to 44,000 passenger vehicle fatalities over the same time frame.
