In the present study, we have employed the ligand-based drug design technique, 3D-QSAR, through a comparative molecular field analysis (CoMFA) and a comparative molecular similarity indices analysis (CoMSIA) to determine the key factors for the plant growth promoting activity of brassinosteroids reported in literature, using the bean second-internode bioassay measured on two groups of compounds...

Nitrogen uptake from various sources by plants capable of biological reduction N2 in symbiotic systems with root nodule bacteria is influenced many factors. The aim the study was to examine influence development stage and variety pea (Pisum sativum L.) cultivated years different temperature precipitation conditions on dynamics nitrogen atmosphere (Ndfa), fertilizer (Ndff), soil (Ndfs). Pre-sowi...

UNLABELLED Most commonly performed laparoscopic surgery is laparoscopic cholecystectomy. Although cholecystectomy through three port is not commonly preferred, researches have shown that it is a safe and feasible way of surgery. Material and Methods. We evaluate 100 patient that have undergone elective laparoscopic cholecystectomy through three port (group one). These patients were compared wit...

One hundred and seven half-sib families of Pinus pinaster planted at four sites in Galicia (NW Spain) were evaluated at age 8 for growth (height, diameter, volume and mean internode length), stem form (straightness, leaning, forking) and branching characteristics (branch diameter, angle and number and total number of whorls). The analyzed half-sib families were obtained from first-generation pl...

To understand the dendritic differentiation in various types of cortical nonpyramidal cells, we analyzed quantitatively their dendritic branching and spine expression. The dendritic internode and interspine interval obeyed exponential distributions with type-specific decay constants. The initial branching pattern, internode interval and spine density at the light microscopic level divided nonpy...

An electron microprobe (EMP) analysis of silica (SiO,) deposition in the epidermis of developing internodes of the perennial scouring rush (Equisetum hyemale var. affine) indicates that SiO, is first detected in the stomata1 apparatus beginning with internode 3, then the epidermal papillae (internode 8), and finally in radial cell walls of the long epidermal cells (internode 10). This process i...

The Mcube network has been proposed in [11] as a highly recursive and symmetrical interconnection network based on twisted links [1]. The Mcube topology has been developed and defined in terms of the structural constraints between components to enforce structural symmetry instead of specifying edges between node pairs. Mcubes have almost half the diameter of a comparable hypercube, a lower aver...

The auxin indole-3-acetic acid (IAA) has been shown to promote the biosynthesis of the active gibberellin (GA(1)) in shoots of pea (Pisum sativum). We used northern analysis to investigate the timing of IAA-induced changes in transcript levels of PsGA3ox1 (Mendel's LE), PsGA2ox1, PsGA2ox2, and PsGA20ox1, key genes for the later stages of GA(1) biosynthesis and metabolism in pea. Rapid (2-4 h) c...

Optimal transmit beamforming is obtained by minimizing the total network transmit power subject to a nodelevel channel capacity constraint. The algorithm that achieves this is referred to as locally enabled global optimization (LEGO)1 and is especially efficient for networks with reciprocal internode transmit and receive channel responses, typically realizable in time division duplex (TDD) netw...

Recent developments in very large scale integration have made it feasible to construct a highly parallel computer composed of large numbers of interconnected microcomputers. The individual nodes of these multimicrocomputer nelworks do not share any common memory. making it crucial to select an interconnecUon network capable of efficiently supporting internode communication. The modeling problem...
