To support decision making on complex environmental issues, models are often used to explore the potential impacts of different management alternatives on the environmental system. We explored how different model outcomes affect decision making. Two topics have our particular interest, namely (1) the influence of quantification of qualitative information on decision making, and (2) the influenc...

BACKGROUND Visceral leishmaniasis (VL) or kala-azar is considered as a parasitic disease caused by the species of Leishmania donovani complex which is intracellular parasites. This systemic disease is endemic in some parts of provinc-es of Iran. The aim of this study was to determine the seroprevalence of VL in Qom Province, central Iran using di-rect agglutination test (DAT). METHODS Overall...

In testing the equality of several variances, it has been shown that the probabilities given by standard tests, derived on the assumption that the samples are drawn from a normal parent population, are subject to large errors when the normality assumption is not satisfied. Therefore a modified form of the F test for testing equality of two variances, when the means are knoim has been developed....

• Rect~t reports on the biosynthesis of tetrahydrobiopterin (BH4) have led to the recognition of 6-pyruvoyl tetrahydropterin (PPH4) as an intermediate of key importance (1-7). Its exact chemical structure has long resisted elu­ cidation; this was partly due to its instability and to the difficulties in obtaining substantial quantities of material. In fact, the only known pro­ cedure for the pre...

8 The increasing availability of Very High Spatial Resolution images enables accurate 9 digital maps production as an aid for management in the agricultural domain. In 10 this study we develop a comprehensive and automatic tool for vineyard detection, 11 delineation and characterization using aerial images and without any parcel plan 12 availability. In France, vineyard training methods in rows...

The potential of an artificial neural network to perform simple non-linear hydrological transformations is examined. Four neural network models were developed to emulate different facets of a recognised non-linear hydrological transformation equation that possessed a small number of variables and contained no temporal component. The 5 modeling process was based on a set of uniform random distri...

Forkhead box A1 (FOXA1) is an FKHD family pro-tein that plays pioneering roles in lineage-specificenhancer activation and gene transcription. Throughgenome-wide location analyses, here we show thatFOXA1 expression and occupancy are, in turn, re-quired for the maintenance of these epigeneticsignatures, namely DNA hypomethylation and his-tone 3 lysine 4 methylation. Me...

thousands of pages of trial reports in the public domain. Other trial reports, such as for oseltami‐ vir and clopidogrel, were obtained through new freedom of information policies at the European Medicines Agency (EMA) that have revolution‐ ised the public’s ability to access trial data. The documents are a substantial resource of information about trials. We expect that other independent group...
