Background: For many primary health care workers in developing countries, the limited availability and cost of public transport hinders timely access to occupational postexposure prophylaxis (PEP) at referral hospitals. Adapted PEP training and a starter's kit (for human immunodeficiency virus, hepatitis B virus, and syphilis prophylaxis) could improve access. Methods: The evaluation method, ba...

considering forage grass species, germination is one of the important stagesconcerning the growing stage that is often influenced by environmental stresses,particularly salinity and drought stresses. thus, this study aims to assess the effects ofsalinity and drought stresses on germination characteristics and seedling growth of desertwheatgrass, agropyron desertorum (fisch. ex link) schult. in ...

salinity and flooding are as two very important factors of soil degradation. they often occur together and cancause severe damage to plants. however, plant response to environmental stresses may vary with growth stage atwhich exposure occurs. a pot study was conducted in 2005-2006 in northern aq qala (northern iran) to studycombine effects of waterlogging and soil salinity at different growth s...

Occupational asthma may be defined as asthma induced by exposure to an inhaled agent (or agents) in the workplace. Its presentation is sometimes dramatic. Occupational exposure to platinum salts, for example, has been known to induce asthma in over 50% of an exposed workforce. For those affected, the consequences are often devastating, while the economic effects for an industry may be no less p...

Occupational therapy is involved in disability prevention and health enhancement through the prevention of occupational dysfunction. Although many occupational dysfunction scales exist, no standard method is available for the assessment and classification of occupational dysfunction, which may include occupational imbalance, occupational deprivation, occupational alienation, and occupational ma...

OBJECTIVES The aim of the study was to develop a model of basic occupational health services (BOHS) in Baoan, which could provide occupational health services (OHS) universally for workers and control occupational hazards. METHODS Steps involved in the BOHS strategy included construction of the BOHS system, capacity building, health training and education, surveillance of workplaces and the h...

Normally, under natural conditions, plants are subjected to the influence of at least two different stress factors. The physiological responses of plants, exposed to two subsequent stress factors differing in their intensity or duration are reviewed. In the experiments presented here, the effects of some natural (water depletion, extreme temperatures), and anthropogenic (UV-B irradiation and he...

Axisymmetrical stresses in an infinitely long hollow isotropic circular cylinder (plane strain) quickly approach their asymptotic values as the external radius increases. This is not the case if the cylinder is even slightly anisotropic -asymptotic solutions (for an infinitely large external radius) do not exist. We find the mechanical meaning of this disparity by using formulas for radial and ...
