precision agriculture is continuously trying to address the sources and factors affecting the in-field variability and taking appropriate managerial decisions. one of the popular research focuses in the recent three decades has been on the development of new approaches to making yield variability maps. advancement in development of sensors and the importance of quality factor in high value crop...

Conformational ensembles are increasingly recognized as a useful representation to describe fundamental relationships between protein structure, dynamics and function. Here we present an ensemble of ubiquitin in solution that is created by sampling conformational space without experimental information using "Backrub" motions inspired by alternative conformations observed in sub-Angstrom resolut...

Abstract Brown hares ( Lepus europaeus Pallas) are able to hybridize with mountain L. timidus Linnaeus) and produce fertile offspring, which results in cross-species gene flow. However, not much is known about the functional significance of this genetic introgression. Using targeted sequencing candidate loci combined mtDNA genotyping, we found ancestral diversity Finnish brown hare be small, li...

Proteomic analysis of dental calculus is emerging as a powerful tool for disease and dietary characterisation of archaeological populations. To better understand the variability in protein results from dental calculus, we analysed 21 samples from three Roman-period populations to compare: 1) the quantity of extracted protein; 2) the number of mass spectral queries; and 3) the number of peptide ...

Variability of endotoxin expression and/or concentration within transgenic cotton (Bt) varieties has been and continues to be a concern of cotton growers, researchers, and breeders. While not a consistent problem, it can cause major economic problems. Transgenic cotton cultivars, to be effective throughout the season, must produce additional levels of proteins that conventional cottons do not. ...

an evaluation of the relationship between crop yield and soil properties would be useful in estimating the fluctuations in yield, and in an implementation of correct field management. the study was conducted in farmer operated wheat fields in sorkhankalateh district, 25 km northeast of gorgan, golestan province, iran. soil samples (0-30 cm depth) were collected just after crop planting at the e...

visit-to-visit variability (vvv) in blood pressure (bp) creates challenges to hypertension control and was independent associated with increased all-cause mortality in hypertensive patients. the major goal of the present study was to investigate the association of vvv in systolic (s)bp with progression of carotid atherosclerosis and en-dothelial dysfunction in on-treated hypertensive patients.o...

abstract fluoride (f-) is an essential element for human and some animals. the fluoride concentration in irrigation water is an important index for water quality. the objective of the present study was to determine spatial variability of fluoride in groundwater and soils of some areas in arak plain. therefore, during two seasons, autumn (2007) and the end of spring (2008), 87 and 92 water sampl...
