dirac operator on the sphere with attached wires

Chinese Physics B 2016年第4期25卷 335-338页

作者： E N Grishanov d a eremin d A Ivanov I Yu Popov Ogarev Mordovia State University Bolshevistskaya Str. 68 Saransk Russia ITMO University Kroverkskiy pr. 49 St. Petersburg 197101 Russia

An explicitly solvable model for tunnelling of relativistic spinless particles through a sphere is suggested. The model operator is constructed by an operator extensions theory method from the orthogonal sum of the dirac operators on a semi- axis and on the sphere. The transmission coefficient is obtained. The dependence of the transmission coefficient on the particle energy has a resonant character. One observes pairs of the Breit-Wigner and the Fano resonances. It correlates with the corresponding results for a non-relativistic particle.

Objective: To determine the effect of a drug STEMB, which is a biostimulating tissue preparation based on chicken embryos, on the morpho-biochemical blood values of dry cows. Methods: The study was conducted on 60 Holstein cows, which were divided into three groups (group 1, group 2, and group 3), with 20 cows in each group. during the experiment, all animals in each group were subjected to the same condition of feeding and maintenance. The experimental animals were administered with the STEMB drug three times subcutaneously at an interval of 7 d within 30 d before calving. Group 1 were given 0.050 mL/kg body weight;group 2 were given 0.075 mL/kg body weight;group 3 were given 0.100 mL/kg body weight. Results: STEMB at 0.075 mL/kg body weight improved the blood cell composition, increasing the erythrocytes, hemoglobin, leukocytes, hemoglobin content, the total protein, albumins, alpha globulins, and gamma globulins. It reduced the beta-globulin index and provided a threshold level for the enzymes alanine aminotransferase, aspartate aminotransferase, and A, M, G immunoglobulins. Conclusions: Use of the STEMB drug with a dose of 0.075 mL/kg body weight given subcutaneously three times at an interval of 7 d within 30 d before delivery is optimal for the prevention of complications during calving and postpartum periods, thereby providing an improvement in the blood cell composition.

由于升级版强子对撞机中的最大粒子能量和亮度的增加,我们需要得到在对撞机磁环附近辐射场更精确的分布,因此我们必须把探测器放在磁环的附近以减小碎片对粒子束的影响.欧洲核子中心(CERN-BE-BI-BL,Rd39)和俄罗斯Ioffe研究所7年前把硅探测器作为一种选择对其开展了研究工作.由俄罗斯Ioffe研究所制作的探测器在1.9K和4.3K温度下对能量为23GeV的质子实时辐射检测中,得到了探测器的特征并由此发现了新的物理现象.

In this study,two novel haptens of oxamichydrazide(OXZ),the metabolite of nifuraldezone,were designed and synthesized by derivatization with ethyl-4-bromobutanoate and ethyl-2-bromoacetate for the first *** rationality of the haptens was enlightened by conformational alignment and electronic evaluations based on computional *** synthesized haptens were efficient in generating antibody response to OXZ.A monoclonal antibody(mAb)named 2d9 with high affinity was obtained and used to establish an indirect competitive enzyme-linked immunosorbent assay(icELISA)for the direct determination of OXZ in chicken samples without the need for derivatization *** optimum conditions,the developed icELISA showed an IC50 value of 0.66 ng mL^(−1),and limit of detection of 0.11μg kg^(−1)in *** average recoveries were found to be 80.4-91.3%with a coefficient of variation less than 9.0%.In conclusion,we have successfully desigened haptens,prepared mAbs and developed an immunoassay for the direct determination of OXZ in chicken samples without the need for a derivatization step for the first *** provides a potentially rapid,accurate,and sensitive screening tool for nifuraldezone residue in animal-derived food.
