  • Physics is what it’s all about. What what’s all about? Everything. That’s the whole point. Physics is present in every action around you. And because physics has no limits, it gets into some tricky places, which means that it can be hard to follow. It can be even worse when you’re reading some dense textbook that’s hard to follow. For most people who come into contact with physics, textbooks that land with 1,200-page whumps on desks are their only exposure to this amazingly rich and rewarding field.

  • Reliable gene-lifestyle interaction studies will yield important evidence for the shaping of personalised healthcare. Studies need statistical power with adequate environmental exposures and lifestyle heterogeneity to obtain reliable evidence on the interplay between nurture and nature. Europe has a historic strength in large epidemiological studies but technology development and implementation is needed to better ascertain environmental exposure and dietary heterogeneity.

  • For many organizations their dependence on information systems, both within the company and networked up and down their supply chain, is now business critical. Any sustained loss of availability of these systems would threaten the very existence of the business. Security is a holistic issue. Vulnerabilities in physical, personnel and electronic security all need to be addressed with equal commitment. Too many businesses still focus on physical security without sustaining even basic precautions in personnel and electronic security....

  • Legend has it that the first diamonds were found in India 8,000 years ago along the Penner, Krishna and Godavari rivers. Prized for their physical qualities, diamonds were used to decorate religious icons and as engraving and polishing tools. From early on, they were associated with wealth, status and well-being. Historians believe the international diamond trade began about 1,000 years ago when traders began transporting rough stones from India across Arabia. The stones were cut and polished before being sold on the European continent to royalty and aristocrats.

  • Socioeconomic status, poverty, and race have been found to be correlated with ACSC rates [8-10]. Several studies have examined the associations between ACSCs and demographics using small areas of analysis (typically ZIP code) and have found that ACSCs are higher in lowincome areas and areas with higher concentrations of racial and ethnic minorities [11,12]. The elderly population has not been studied much in this context, because they are thought to be relatively well-insured.

  • This uncommon type of skin cancer develops from neuroendocrine cells (hormone-making cells that resemble nerve cells in some ways) in the skin. They are most often found on the head, neck, and arms but can start anywhere. These cancers are thought to be caused in part by sun exposure and in part by Merkel cell polyomavirus (MCV). About 8 out of 10 Merkel cell carcinomas are thought to be related to MCV infection. MCV is a common virus. Many people are infected with MCV, but it usually causes no symptoms. In a small portion of people with this infection,...

  • The 10 problems of least concern are generally issues of limited exposure to most small-busi- ness owners and typically find themselves at the bottom of the ranking each year. Three prob- lems are new to the top 10 of least concern and one problem in the group is new to the survey. “Exporting My Products/Services” holds onto the 75th ranking, a position held for six of seven editions that it has been listed as a problem. It moved up one position in 2000, replaced by the problem “Y2K Impacts.

  • Tritium, the heaviest and only radioactive isotope of hydrogen, is increasing in importance in energy and environmental considerations. This nuclide is widely distributed throughout man's environment because of its ubiquitous form as tritiated water and its persistence in the environment. This report considers and evaluates the available information on tritium in terms of its physical properties, production sources, physical transport, biological behavior, projected future production, waste management, and the long-term dose implications of tritium in the environment....

  • Recent studies have used as a reference group women who had no exposure to tobacco smoke - that is, they have never actively or passively smoked. These studies in most cases have reported increases in breast cancer risk for women who smoked or were passively exposed to tobacco smoke compared to reference women who were never exposed. Critics of this approach cite studies that indicate the reference women who have never been exposed to tobacco smoke are healthier, in general.

  • The traditional view that expected nominal rates of return on assets should move one-for- one with expected inflation is first attributed to Irving Fisher (1930). Financial economists have also argued that, because stocks are claims on physical, or “real”, assets, stock returns ought to co-vary positively with actual inflation, thereby making them a possible hedge against unexpected inflation.

  • Control. Research suggests that an organism’s perception of control during stressful events is very important to both psychological and physical health. For example, cancer- ous tumor growth has been found to be enhanced in rats exposed to inescapable shock compared to tumor growth in rats given escapable shocks (Sklar & Anisman 1979; Vis- intainer, Volpicelli, & Seligman, 1982). Several studies have shown that increasing indi- viduals’ sense of control can have profound health implications.

  • Control of ectoparasites on poultry creates additional exposure risks. High pressures sprays or dipping are often used in large commercial operations to treat birds for obligate ectoparasites such as the northern fowl mite. Aerosol and splash represent exposure risks for the applicator in both situations. Routes of entry may be oral, dermal or inhalation. Dipping represents the most significant risk to personnel since each bird must be handled to effectively treat the outbreak. A significant amount of splash occurs as birds are immersed and withdrawn from the dipping vat.

  • Although major trends may emerge and show numerous toxic effects related to certain NP, it can be seen that each product, and even each synthesized NP batch, can have its own toxicity. Any process or surface modification can have an impact on the toxicity of the resulting product. Given this context, the authors of this report consider that the IRSST should favour the introduction of strict prevention procedures, which remain the only way to prevent the development of occupational diseases.
