Soil and plant hydraulics constrain ecosystem productivity by setting physical limits to water transport and hence carbon uptake by leaves. While more negative xylem water potentials provide a larger driving force for water transport, they also cause cavitation that limits hydraulic conductivity. An optimum balance between driving force and cavitation occurs at intermediate water potentials, th...

This paper gives an overview of computer graphics representations of trees commonly used for the rendering of complex scene of vegetation. Looking for the right compromise between realism and efficiency has lead researchers to consider various types of geometrical plant models with different types of complexity. To achieve realist plant model, a complex structure of plant with full details is g...

The existence of Metabolic Gene Clusters (MGCs) in plant genomes has recently raised increased interest. Thus far, MGCs were commonly identified for pathways of specialized metabolism, mostly those associated with terpene type products. For efficient identification of novel MGCs, computational approaches are essential. Here, we present PhytoClust; a tool for the detection of candidate MGCs in p...

materials and methods twelve natural compounds jaceosidin, withaferin a, curcumin, epigallocatechin-3-gallate (egcg), artemisinin, gingerol, ursolic acid, ferulic acid, berberin, silymarin, resveratrol, and indol-3-carbinol were docked against e6 and e7 oncoproteins of high-risk hpv types 16 and 18 using a protein-ligand docking software called autodock4.2. results out of these 12 natural compo...

Electricity generation in thermal power plants as the largest producer of electricity in Iran is associated with greenhouse gas emissions. In this paper, using the Malmquist-Luenberger method, green productivity, and efficiency changes are measured for 31 thermal power plants (including 12 steam power plants, 13 gas power plants, and six combined cycle power plants) during 2009-2016. The result...

Soil microbial diversity is an important index of agricultural productivity (Nimisha Sharma et al,.2010; Kent and Triplett, 2002; Isik, 2008). Both plant and the soil types influences the microbial diversity. Rhizosphere microbial diversity usually influenced by both plant and soil types. Plants and microorganisms interact with each other and co evaluate together. Their balance is important for...

in the present study resistance of some elite lines of wheat at seedling stage were evaluated in cereal rusts greenhouse at seed and plant improvement institute in karaj and at adult plant stage in ahvaz under artificial inoculation with an isolate of leaf rust from ahvaz. for seedling resistance, different components of resistance were measured. the results showed that lines m-85-1, m-86-1 and...

Piston plays a vital role in almost all types of vehicles. The present study discusses the behavioral study of a piston manufacturing plant. Manufacturing plants are complex repairable systems and therefore, it is difficult to evaluate the performance of a piston manufacturing plant using stochastic models. The stochastic model is an efficient performance evaluator for repairable systems. In...
