Abstract In multistage axial compressors of gas turbine engines, there is a need for detailed understanding the flow field in between blade rows, which could be obtained by spanwise traversing. This requires pneumatic probe to immersed into path where space limited. Therefore, will affect around it and channel, readings affected that field. As result, these cannot translated parameters based on...

Ammonia (NH3) emissions resulting from the field application of livestock slurry has both negative human health and environmental impacts. However, decreasing exposed surface area (ESA) upon can reduce NH3 volatilization by limiting its atmospheric exposure. In present study, three strategies for depositing within a growing crop were studied, including: 1. standard trailing hoses (SAhose), 2. s...

Rapidly warming climate, tightening environmental requirements, an aging society, rising wages, and demand for organic products are forcing farming to be more efficient sustainable. The main aim of this study was perform analytical analysis determine the energy use GHG emissions sugar beet production using different weed control methods. Seven methods non-chemical were compared. Mechanical inte...

Huang-Huai-Hai Plain is the most important region for grain production in China. In this area, long-term rotary tillage winter wheat and no summer maize have significantly increased soil bulk density, which impede root growth reduce yield. Subsoiling an effective practice to improve properties crop growth. The objective of study was investigate integrated effects subsoiling both seasons on spat...

Let A and B be n × m matrices. The matrix B is said to be g-row majorized (respectively g-column majorized) by A, if every row (respectively column) of B, is g-majorized by the corresponding row (respectively column) of A. In this paper all kinds of g-majorization are studied on Mn,m, and the possible structure of their linear preservers will be found. Also all linear operators T : Mn,m ---> Mn...

Tillage is the main force of soil redistribution in agricultural land use and has been seen as more critical than water erosion. This study aims to evaluate effect tillage with standard disk vineyards. A representative area grapevines was selected, 39 inter-rows were selected test slope forward speed. In each inter-row, a strip collected, mixed 2 kg coloured sand used tracer, then replaced stri...

A non-binary (2,v)-regular LDPC code is defined by a parity-check matrix with column weight 2 and row weight v. In this report, we give an ontology-based approach to the optimization for this class of codes. All possible inter-connected cycle patterns that lead to low symbol-weight codewords are identified to put together the ontology. The optimization goal is to improve the distance property o...

in order to study the productivity and competition ability of sesame and mung bean, a field experiment was conducted in agriculture faculty of shahid chamran university of ahvaz at 2012. experimental design was split-plot based of rcb with 3 replications. main plot included 2 planting patterns and sub-plots included 5 plant density ratios. our result showed that both 50 & 75 cm inter-rows in 50...

Introduction The Netherlands are actively involved in atmospheric composition measurements from space since 1995 with measurements from the GOME, sCIAMAChY and OMI satellite instruments. The MetOp satellite series with GOME-2 onboard will continue these measurements until 2020, thereby providing an important global climate data record. KNMI plays an active and often leading role in the analysis...
