BACKGROUND Quantitative structure-activity relationships (QSAR) analysis of peptides is helpful for designing various types of drugs such as kinase inhibitor or antigen. Capturing various properties of peptides is essential for analyzing two-dimensional QSAR. A descriptor of peptides is an important element for capturing properties. The atom pair holographic (APH) code is designed for the descr...

O clorofilômetro (SPAD-502) é amplamente utilizado para estimar teores de clorofila, mas a falta de uniformidade na distribuição dos cloroplastos pode afetar sua precisão. Os objetivos deste estudo foram avaliar o efeito da fluência de fótons (F = irradiância x tempo de iluminação) em folhas com teores diferentes de clorofila e determinar o efeito da relação clorofila a/b nos valores do SPAD em...

ABSTRACT Powdery mildew is an important disease in tomato, which requires technologies for its control. Homeopathy a science that has been improved as alternative method agriculture. Thus, this study aimed to evaluate the homeopathic medicine Ferrum sulphuricum 6, 12, 24, 48, 72 and 96CH dynamizations on powdery The experiment was conducted from May June 2013 greenhouse, split-split- plot desig...

Plant growth promoting rhizobacteria (PGPR) can improve the growth, productivity and tolerance of plants under stress conditions. The aim this study was to investigate effect PGPRs on physiological traits related photosynthesis, canopy temperature (CT) yield tomato hybrids water scarcity in open field Seedlings H-1015 UG 812J F1 were treated by B1, B2, B3 bacteria strains before planting, then ...

In their article in Critical Care, Sponholz et al. [1] compared two devices: the molecular adsorbent recirculating system (MARS) and single pass albumin dialysis (SPAD). As Sponholz et al. claim, SPAD is not an effective method for achieving a significant decrease in the concentration of bile acids, creatinine or urea, because a single SPAD procedure induces a 7.62 % (median) reduction in the l...

Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 50: 7.13 7.20. This study investigated the potential of support vector machine (SVM) methodology to extract information on crop growth...

Essential oils from aerial parts of Mentha spicata, was obtained by steam destillation using a Clevenger-type system. These oils were screened for antibacterial and anti-Candida albicans activity using bioautographic method. A fiel experiments was laid out in agricultural research farm, city Namin, Ardabil province, Iran in 2013. Experiment was conducted in a randomized complete block with seve...

Estimation of crop biophysical and biochemical characteristics is the key element for growth monitoring with remote sensing. With application unmanned aerial vehicles (UAV) as a sensing platform worldwide, it has become important to develop general estimation models, which can interpret data crops by different sensors in agroclimatic regions into comprehensible agronomy parameters. Leaf chlorop...

The elevating temperature makes heat stress one of the major issues for wheat production globally. To elucidate genetic basis and map tolerance QTLs agroecology State Bihar under NEPZ, a set 166 doubled haploid lines (DHLs) derived from cross between PBW343/IC252874 was used. population evaluated normal sown (NS) late (LS) conditions two cropping seasons. canopy (CT) showed positive correlation...

Farmers must balance the competing goals of supplying contributions of background reflectance, while spectral vegetation indices that combined reflectances of near-infrared adequate N for their crops while minimizing N losses to the environment. To characterize the spatial variability of N and other visible bands (MCARI and NIR/Green) were responsive to both leaf chlorophyll concentrations and ...
