Small-angle neutron scattering (SANS) is employed to investigate the structure and longchain branch (LCB) content of metallocene-catalyzed polyethylene (PE). A novel scaling approach is applied to SANS data to determine themole fraction branch content (φbr) of LCBs in PE. The approach also provides the average number of branch sites per chain (nbr) and the average number of branch sites per min...
Increasing planting density is one of the key management practices to enhance soybean yield. A 2-yr field experiment was conducted in 2018 and 2019 including six densities two cultivars determine effects on branch number yield, analyze contribution branches The yield ZZXA12938 4389 kg ha−1, which significantly higher than that ZH13 (+22.4%). In combination with year cultivar, increased by 16.2%...
Due to the increasing need of the country to imported edible oil and rapeseed importance among oilseeds, efforts to increase its grain yield and oil content are of high importance. Therefore, recognizing the traits that increase grain yield of rapeseed has an important role in the success of breeding programs. Thus, sixteen rapeseed genotypes were evaluated in a randomized complete block design...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
Abstract: The motive of the study is to establish a seepage flow model of pinnate horizontal well in infinite reservoir according to the characteristics of 3D distribution of CBM pinnate horizontal well. Taking flow pressure drop along the main and branch boreholes into consideration, the fluid flow formulas of CBM pinnate horizontal well are proposed. The corresponding calculation program has ...
inadequate attention to the products having shelf life limitation leads to form a new branch of supply chain (sc) called cold chain (cc). cold chain management (ccm) is referred to handle activities related to perishable products. this research investigates the role of information technology (it) in improving the human resource efficiency, planning and logistic in the cc organizations. the numb...
The purpose of this study is to investigate the relationship between risk-taking behavior and performance of Bank Melli Iran branches located in the West Azerbaijan province of Iran. The performance is measured by the profitability index, i.e. profit-to-income ratio in the Bank Melli Iran branches of the West Azerbaijan province. The research data covers all the branches in the area within a si...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
