The relationship between alcohol consumption and the risk of cardiovascular disease has now been studied for over fifty years, and confirmed in multiples case-controlled and cohort studies, and subsequent meta-analyses of these studies. Sound experimental and clinical studies of plausible biological mechanisms support that there is a causal relationship between alcoholic beverages and cardiovas...

 Field experiment was carried out to study the effect of different tillage systems and skipping irrigation at growth stages along with or without foliar applied potassium on phenology, yield maize hybrid. Results revealed that maximum grains per cob (381), 1000-grains weight (281.00 g), grain (7.82 t ha-1) biological (14.78 were observed in conventional system as compared zero tillage. Re...
Benthic macroinvertebrate assemblages have become part of the arsenal of tools used to assess and monitor biological health or integrity of surface waters. These communities are particularly well suited for such uses, since their relatively long lives, complex life cycles, and varying sensitivities mean that there is ample time for an interpretable response to environmental perturbations to occ...
Macrobrachium tenellum and M. americanum are common freshwater prawns from the Americas' tropical subtropical Pacific continental side. They have different biological attributes currently threatened by human impact on their ecosystems. Both species provide quality products for consumption intensively exploited without proper management. This study analyzes, discusses, compares available informa...
The symbolic representation of the physical structure of living organisms needs an ontologically well-founded and logically sound approach so that formal reasoning can adequately be supported. We describe a set of canonical relations and attributes necessary for the description of biological structures. Based on these epistemological primitives, we sketch how a broad range of organisms can be r...
Biological Attributes of Ethylene: Colorless gas at biological temperatures. Naturally occurring organic compound. Readily diffuses from tissue. Produced from methionine via ACC by a highly regulated metabolic pathway. Key enzymes are ACC synthase and ACC oxidase. C2H4 synthesis is inhibited by C2H4 in vegetative and immature reproductive tissue. C2H4 synthesis is promoted (autocatalytic) by C2...
The cyclic variation in the energy envelope of the speech signal results from the production of speech in syllables. This acoustic property is often identified as a source of information in the perception of syllable attributes, though spectral variation can also provide this information reliably. In the present study of the relative contributions of the energy and spectral envelopes in speech ...
We propose a method, called PREDIQT, for model based prediction of impact of architecture design changes on system quality. PREDIQT supports simultaneous analysis of several quality attributes and their trade-offs. This paper argues for the feasibility of the PREDIQT method based on a comprehensive industrial case study targeting a system for managing validation of electronic certificates and s...
The KIV model is a biologically inspired neural network that can exhibit non-linear electrical brain activity found in the limbic system of the brain. One such behavior exhibited in brain activity is cognitive processing. Spatial patterns of beta-gamma EEG emerged following sudden jumps in cortical activity called “phase transitions”. The interaction between entorhinal cortex (EC), amygdala, an...
We consider the use of distant supervision for biological information extraction, and introduce two understudied corpora of this form, the Biological Expression Language (BEL) Large Corpus and the Pathway Logic (PL) Datum Corpus. Each resource eschews annotation at the sentence constituent level, and the PL corpus requires synthesis of information across multiple sentences to construct composit...
