Demographic viability of populations of \u3cem\u3eSilene regis\u3c/em\u3e in midwestern prairies: relationships with fire management, genetic variation, geographic location, population size and isolation [PDF]
, 1998 We studied the demographic viability of populations of a long-lived iteroparous prairie perennial, Silene regia, in relation to management regimes, population sizes, geographical region (Ohio and Indiana vs.

American Journal of Industrial Medicine, EarlyView.ABSTRACT Background Since 1997 the Building Trades National Medical Screening Program (BTMed) has offered medical exams to construction workers employed in US nuclear weapons facilities. The process consists of two steps: (1) a detailed work history interview; and (2) a medical exam.

Annals of Neurology, EarlyView.Objective Quaking‐induced conversion (QuIC) tests, which detect prion‐seeding activity in cerebrospinal fluid (CSF), have markedly advanced the antemortem diagnosis of prion diseases such as Creutzfeldt‐Jakob disease (CJD). These tests provide high diagnostic accuracy and enable timely differentiation from other rapidly progressive neurodegenerative ...

Border Disease Virus: an exceptional driver of chamois populations among other threats
Frontiers in Microbiology, 2015 Though it is accepted that emerging infectious diseases are a threat to planet biodiversity, little information exists about their role as drivers of species extinction. Populations are also affected by natural catastrophes and other pathogens, making it

Stochastic models of population extinction
, 2010 Theoretical ecologists have long sought to understand how the persistence of populations depends on biotic and abiotic factors. Classical work showed that demographic stochasticity causes the mean time to extinction to increase exponentially with ...

Management and research efforts are failing dolphins, porpoises, and other toothed whales
Scientific ReportsDespite being subject to intensive research and public interest many populations of dolphins, porpoises, and other toothed whales (small cetaceans) continue to decline, and several species are on the verge of extinction. We examine small cetacean status,

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In the pulverized coal boiler industry, reducing NOx emissions has become a critical objective. Although low‐NOx combustion technologies are effective, they may lead to localized high‐temperature corrosion. To address this issue, near‐wall air supply technology has been introduced, which involves injecting an appropriate amount of air near the
