Abstract Climate change, extreme weather phenomena, droughts, fires etc. are just few examples of man-induced impact, jeopardizing the future mankind. Businesses increasingly held responsible for and try to manage their environmental impact. Environmentalism lately sustainability (manifesting an equal pursuit environmental, social, economic goals) guide strategic orientation. Whereas large corp...

Concepts of a CELSS anticipate the use of photosynthetic organisms (higher plants and algae) for air revitalization. The rates of production and uptake of carbon dioxide and oxygen between the crew and the photosynthetic organisms are mismatched. An algal [correction of aglal] system used for gas exchange only will have the difficulty of an accumulation or depletion of these gases beyond phys...

BACKGROUND In ecologic studies, group-level rather than individual-level exposure data are used. When using group-level exposure data, established by sufficiently large samples of individual exposure assessments, the bias of the effect estimate due to sampling errors or random assessment errors at the individual-level is generally negligible. In contrast, systematic assessment errors may produc...

BACKGROUND It is puzzling to note that British and Danish citizens have a poorer cancer prognosis than citizens from other countries, and this study hypothesises that their low cancer survival could be partly rooted in the gatekeeper function undertaken by general practice in these two countries. AIM To test the association between principles of gatekeeper systems and cancer survival. DESIG...

BACKGROUND The field of risk assessment has focused on protecting the health of individual people or populations of wildlife from single risks, mostly from chemical exposure. The U.S. Environmental Protection Agency recently began to address multiple risks to communities in the "Framework for Cumulative Risk Assessment" [EPA/630/P02/001F. Washington DC:Risk Assessment Forum, U.S. Environmental ...

background: although several in vitro and animal studies have suggested that isoflavones might exert inhibitory effects on gastric carcinogenesis, epidemiologic studies have reported inconclusive results in this field. the aim of this brief review was to investigate whether such an association exists among dietary isoflavones and gastric cancer incidence, prevention, and mortality in epidemiolo...
