Conclusions It has been established by kinetic and spectral methods that the cyclohexadiene carbene generated in the photolysis of 2,6-di-tert-butyl-1,4-benzoquinone diazide in benzene predominantly in the singlet state reacts with benzene to form a norcaradiene derivative, which isomerizes thermally to 4-phenylcyclohexadiene-2,5-one. The latter is converted thermally to 2,6-di-tert-butyl-4-phenylphenol.Translated from Izvestiya Akadeinii Nauk SSSR, Seriya Khimicheskaya, No. 12, pp. 2680–2685, December, 1986. 相似文献

Background
In learning and memory tasks, requiring visual spatial memory (VSM), males exhibit superior performance to females (a difference attributed to the hormonal influence of estrogen). This study examined the influence of phytoestrogens (estrogen-like plant compounds) on VSM, utilizing radial arm-maze methods to examine varying aspects of memory. Additionally, brain phytoestrogen, calbindin (CALB), and cyclooxygenase-2 (COX-2) levels were determined. 相似文献4.

Results are given in this paper of a study of the electrical forming process in thin-film MDM systems based on films of silicon oxynitride of varying compositions. It was observed that the forming voltage and forming rate of a thin-film Al-SixNyOz-Al system depends essentially on the composition of the dielectric film while the characteristics of the formed structures depend weakly on the oxygen/nitrogen ratio in the film. The results obtained are in good agreement with Shnurov's model of forming.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 5, pp. 71–74, May, 1976. 相似文献

In this paper Jeffery–Hamel flow has been studied and its nonlinear ordinary differential equation has been solved through homotopy analysis method (HAM). The obtained solution in comparison with the numerical ones represents a remarkable accuracy. The results also indicate that HAM can provide us with a convenient way to control and adjust the convergence region. 相似文献
