The no-tillage system is perceived as having lower soil temperatures, wetter soil conditions, and greater surface penetration resistance compared with conventional and other conservation tillage systems. Concerns associated with the effect of the no-tillage system on certain soil physical properties (i.e. soil temperature, moisture, and compaction) prompted this study to evaluate the effect of ...

This research was aimed to identify the main factors that influence performance rate of plow-type trenchless machine and mathematically correlate these variables predict rate. The mathematical analysis ended with an equation correlating affecting it. derived relationship checked in various operational circumstances. rate's practical experiments revealed only for 0.92 0.76 m disturbed soil depth...

An improved whole cell pertussis vaccine, designated as Plow, which is low in endotoxicity due to a chemical extraction of lipo-oligosaccharide (LOS) from the outer membrane, was evaluated for safety, immunogenicity and potency, comparatively to a traditional whole cell pertussis vaccine. Current whole cell pertussis vaccines are effective but contain large quantities of endotoxin and consequen...

Prefix 10.18034 This performance evaluation was conducted to pave the way for making use of Draught Animal Power Cultivator and cosequently possibilities of adaptation in our local condition between 2010 and 2011 in the Jimma zone two districts of southwestern Ethiopia on the farmers’ field to evaluate energy requirement. To improve weed management at the small holder farmers level, animal-draw...

During skeletal muscle development, nuclei move dynamically through myotubes in a microtubule-dependent manner, driven by the microtubule motor protein kinesin-1. Loss of kinesin-1 leads to improperly positioned nuclei in culture and in vivo. Two models have been proposed to explain how kinesin-1 functions to move nuclei in myotubes. In the cargomodel, kinesin-1 acts directly from the surfaceof...

energy consumption in iran is a subject of debate. some may think that oil is cheap in iran and thus no need for this kind of research. this simple minding is erroneous first because iran subsidizes billion dollars each year for the imported diesel fuel specially for agricultural use and second because energy studies reveal the degree of professionally using the technology. we can easily find t...

Widespread premature termination codon mutations (PTCs) were recently observed in human and fly populations. We took advantage of the population resequencing data in the Drosophila Genetic Reference Panel to investigate how the expression profile and the evolutionary age of genes shaped the allele frequency distribution of PTCs. After generating a high-quality data set of PTCs, we clustered gen...

The study aims to substantiate the design scheme of a linear plow with disk angle. authors have developed for smooth, furrowless plowing. proposed has disc lugs, screw housings, and guide plates. technological turnover polygonal layers formed by pre-plates, mutual arrangement housings plates, general view laboratory-field installation conducting experiments are given. During experiments, degree...
