Transparent zinc oxide（ZnO） thin films are fabricated by a simple sol-gel spin-coating technique on glass substrates with different solution concentrations（0.3-1.2 M） using zinc acetate dehydrate [Zn（CH_3COO）_2·2H_2O] as precursor and isopropanol and monoethanolamine（MEA） as solvent and stabilizer, respectively. The molar ratio of zinc acetate dehydrate to MEA is 1.0. X-ray diffraction, ultraviolet-visible spectroscopy and photoluminescence spectroscopy are employed to investigate the effect of solution concentration on the structural and optical properties of the ZnO thin films. The obtained results of all thin films are discussed in detail and are compared with other experimental data.

Using the full potential linearized augmented plane wave FP-LAPW method within local density ap-proximation LDA, we have studied positron diffusion and surface emission in Cd-based semiconductors. This requires the calculation of electron and positron band structures. In the absence of experimental and theoretical data for CdX (X=S,Se,Te) we have treated the Si, which has been studied by several authors, as a test case. Predictive results on positron effective masses, deformation potentials, positron work functions, diffusion constants and positron mobilities are presented for CdX (X=S, Se, Te). Our calculated data for Si are compared with experimental and recent theoretical results.

This paper will assess the way in which consumerism is used to manipulate individuals within marginalized groups, specifically those based on race and gender. Following a Marxist framework, this paper will illustrate a symbiotic relationship between the laborer and the capitalist, a hierarchal relationship where mutual dependence encourages unrelenting exploitation. Further focus will center on how these social hierarchies perpetuate a continuous enslavement of individuals politically defined as black and politically defined as woman. These identities are outlined within the framework of two active dichotomies： black/white and man/woman. Both gender and race are key factors in determining an individual＇s identity. Because the hegemonic gender is man, while the hegemonic race is white, any person who does not fit into those two categories simultaneously is underprivileged. Hence the reason why black and woman, both of which have been historically deemed subordinate to white and man, is automatically a part of the underprivileged working class. Since the hierarchal laborer-capitalist relationship is greatly validated by socializations, it cannot be voided by taking legal action alone. However, policy changes addressing education gaps, gender wage gaps, and hiring discrepancies, can assist in decoupling the social constructs of race and gender from class therefore minimizing racial and gender privileges.

Effects of cultivation of Puccinellia tenuiflora on the chemical and physical characteristics of alkalinized soil in western areas of Jilin

作者： Masahiro Yukawa Shun-ichi amari Brain Science Institute RIKEN Japan Dept. Electrical and Electronic Engineering Niigata University Japan

This paper addresses extensions of the Least Angle Regression （LARS） algorithm from two different aspects: （i） from quadratic to more general objectives, and （ii） from l1 -norm to lp -norm for p ＜ 1 . The equiangular vector, which is the key of LARS, is reproduced in connection with the Riemannian metric induced by the objective function, thereby making the extensions feasible. It is shown, in the case of p ＜ 1 , that two types of trajectory-the c-trajectory and the λ-trajectory-need to be distinguished by revealing the discontinuity of the λ-trajectory.

Research results concerned （ 1 ） quantification of pH value and contents of ammonia nitrogen, volatile fatty acids （VFAs）, and lactic acid, which were indicators of fermentative quality of corn stover silage and other crop by-product silages ; （2） introduction of methods for analyses of fiber content in feeds such as detergent and enzymatic analyses; （3） determination of digestive characteristics in the tureen by artificial digestion trials （ in vitro and in situ ） ; （ 4 ） evaluation of meat productivity and quality by feeding corn stover silage to beef cattle in feeding experiments and; （5） preparation of feed composition and feeding standards for animals in Jilin Province. These results and methods substantially contributed to stabilization of feed supply as well as an increase in the efficiency of meat production, resulting in sustainable development of livestock management in China.
