Abstract The superconductivity of the FeSe-based superconductor is extremely sensitive to Fe vacancies in FeSe plane. In order reduce formation plane, various low-temperature methods are developed. However, it still complex and time consuming control concentration. Here, a hybrid iron-based superconductor, Li 0.21 Se 0.05 (EG) 0.26 (EG: ethylene glycol, C 2 H 6 O ), synthesized by solvothermal ...
تمرکز یکی از مهم ترین عناصر ساختار بازار میباشدکه به نحوه توزیع قدرت بازار میپردازد. تمرکز جغرافیایی به عنوان یکی از ابعاد تمرکز معرفی شده است که نحوه تقسیم قدرت بازار را از لحاظ جغرافیایی در میان مناطق مختلف درنظر می گیرد و میزان یکنواختی و تجانس توزیع فعالیت های اقتصادی بین مناطق را مورد ارزیابی قرار می دهد، بطوری که این نوع ارزیابی در زمینه شناخت چگونگی ساختار صنعت و سیاستگذاری های صنعتی و ا...
We prove that if a group G is systolic, i.e. if it acts properly and cocompactly on a systolic complex X, then an appropriate Rips complex constructed from X is a finite model for EG.
this study explored the effects of gnrh agonist (gnrha) immunity on expression of fshr mrna in pituitary and fshr protein in uteri, and also confirmed its efficacy on uterine development. 42 prepuberty and non cyclic ewes were assigned to 6 experimental groups (eg) during anestrus season. animals in eg-i, eg-ii and eg-iii were subcutaneously injected with 200, 300 and 400 μg alarelin antigens (...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
Bose-Einstein correlations are of interest to the LEP community as a source of systematic error in W-mass determinations (for example [1–4]), and also to the Heavy Ion community (see [5,6]) as a valuable measurement tool for the size of the fireball created in heavy ion collisions (eg. [7] and refs therein). Due to limited statistics, measurements of BE enhancement at LEP are often made in term...
