Men and women at Northwest University （n=751）, Xi＇an, China were asked to judge the attractiveness of photographs of female patients who had undergone micrograft surgery to reduce their waist-to-hip ratios （WHR）. Micrograft surgery involves harvesting adipose tissue from the waist and reshaping the buttocks to produce a low WHR and an ‘hourglass＇ female figure. This gynoid distribution of female body fat has been shown to correlate with measures of fertility and health. Significantly larger numbers of subjects, of both sexes, chose post-operative photographs, with lower WHRs, as more attractive than pre-operative photographs of the same women. Some patients had gained, and some had lost weight, post-operatively, with resultant changes in body mass index （bMI）. However, these changes in bMI were not related to judgments of attractiveness. These results show that the hourglass female figure is rated as attractive in China, and that WHR, rather than bMI, plays a crucial role in such attractiveness judgments.

In this paper, we present the exact solution of the one-dimensional Schrrdinger equation for the q-deformed quantum potentials via the Nikiforov-Uvarov method. The eigenvalues and eigenfunctions of these potentials are obtained via this method. The energy equations and the corresponding wave functions for some special cases of these potentials are briefly discussed. The PT-symmetry and Hermiticity for these potentials are also discussed.

The upgrade of the MAX-lab injector and the construction of MAX Ⅲ, provided the opportunity for upgrading the tagged-photon facility and thus lead to the possibility of more extensive program in nuclear physics research. This upgrade increased the injected electron energy to an eventual maximum of 250 MeV and allows for the extraction of electrons from the MAX Ⅰ ring operated in the stretcher mode. The first stretched beam was delivered in September 2005. The tagged-photon facility was commissioned in parallel with the commissioning of new experimental equipment. The PAC approved experimental program is current in progress, including measurements of pion photoproduction below the △（1232）. The efforts at the tagged photon-facility are pursued within an international collaboration with around fifty members.

A series of poly(phenylenevinylene) (PPV)/titanium oxide (TiO_2)nanocomposites with different contents of TiO_2 nanoparticles were prepared from mixtures of PPVprecursor and titanium butoxide ethanol solution in a sol- gel process. TEM images showed theformation of the connected network of TiO_2 nanoparticles with a higher content of TiO_2, whichresulted in the titanium butoxide hydrolyzed to form Ti organic compound. Meanwhile, the conjugationof PPV polymer chains can be interrupted by the TiO_2 network structure. The PL spectra revealedthat the emitted light of the PPV/TiO_2 nanocomposites blue shifted without fine structure and thePL intensity enhanced when the TiO_2 network formed. In the lifetime spectroscopy of positronannihilation, the structural properties of the PPV dominated the character of the nanocomposites, inwhich the formation of the omicron -Ps was presented in free volume polymer, when the content ofTiO_2 was below 10 percent. Further increasing the content of TiO_2 nanoparticle introduced muchmore vacancies, vacancy clusters and grain boundaries at their interfaces, which led to thecorresponding lifetime and intensity close to that of the nano- TiO_2 bulk materials. With the TiO_2content of 50 percent of long lifetime. These phenomena suggested that the optical and structuralproperties of the PPV/TiO_2 nanocomposites are dependent on the interfacial structure between PPVand TiO_2 nanoparticles.

本文有三重目的。首先,论述各种关于泰人故土的看法和对可以找到的这些看法的证据进行评价;第二,提供一个在该问题上的新发现的详细目录和指明对这些领域的进一步研究是必要的;第三,本人主张就泰人的仪式进行比较是再现原始泰文化的一种方法,并提出这种再现可以提供历史和考古之间的一种重要的联系。最后,对东山文化和泰文化之间可能存在某种联系提出一些思索。

当今,加拿大华裔的人数不多,约为三十万,占全加人口的1.5%。近年来加拿大移民政策有所改变,以及1997年香港将回归大陆,华人移居加拿大的数量也许在今后十年内有所增加。加拿大华裔较少并不是偶然的,而是长久以来加拿大政府在移民问题上采取种种歧视政策的结果,也是欧裔加拿大人排外心理作用的结果。本文将对决定华裔人数以及制约华人移居加拿大后生活状况的社会、经济条件,作一简略考察。首批华人移居大不列颠哥伦比亚省,是正值弗雷泽河流(Fraser Valley)发现黄金的19世纪50年代。他们中的一些人来自美国加州,曾在那儿当过矿工,而另一些人直接来自于中国。他们作为廉价劳动力颇受欢迎,因为当时采矿业以及铁路。
