(i)避孕流行指数增长目的在于缩小家庭规模。(ii)私人经济团体而不是国家支持的家庭计划组织在巴西生育率转化过程起决定作用。(iii)生育率下降原因是由极有效避孕措施带来的婚育率下降。总论:据巴西1986年人口与健康调查,全国平均妇女终生生育率降至3.3。南方各州生育总数大体相同(为2.4—2.6),北方各州相对高些(为5.1)。资料分析得出的结论是70年来全国都经历了生育率急速下降。1986年15—44岁已婚妇女避孕流行指数达66%,三十来岁的妇女尤其盛行。3/4的妇女都采取节育措施和使用口服避孕药,而妇女节育者居多。近十年避孕流行指数达到登峰造极的地步。

Gesture and action recognition for video surveillance is an active field of computer vision. Nowadays, there are several techniques that attempt to address this problem by 3D mapping with a high computational cost. This paper describes software algorithms that can detect the persons in the scene and analyze different actions and gestures in real time. The motivation of this paper is to create a system for thetele-assistance of elderly, which could be used as early warning monitor for anomalous events like falls or excessively long periods of inactivity. We use a method for foreg-round-background segmentation and create a feature vectorfor discriminating and tracking several people in the scene. Finally, a simple real-time histogram based algorithm is described for discriminating gestures and body positions through a K-Means clustering.

在北京居住的九年里,我总是生活在黯淡的光线里。家里的光线经常不足,透过小小的窗户,只能看见北京灰色和多云的天空,其实,在这样的环境里,即使你的公寓朝南,室内的光线也还会很暗。我们现在的家却布满阳光,恰好与中国的传统相反,房子的朝向是向北的,巨大的落地窗户可以捕捉到北京的每一缕优美光线,往往在清晨时就有的阳光穿过深色的木窗,温柔、平缓、安静地停栖在每一间屋子里。北边的屋子是给艺术家准备的,在那里可以获得最好的光线绘画;而在北京,不同于传统观念,朝北的屋子也同样生动美丽。

Toxoplasmosis is a parasitic infection whose clinical presentations depend on the human’s immune response. They can range from asymptomatic to rapidly progressive and deadly. There are no data on this disease in our population. Therefore, we have proposed to know the seroprevalence of toxoplasmosis in population risk groups through a descriptive, exploratory study in the 3 most populated districts of the province of Huancayo. The samples were processed by ELISA method and there were a total of 169 samples, 85 pregnant women and 84 cancer patients. The seroprevalence found in pregnant women was 44.7% and in cancer patients it was 26.2%. Finally, the only risk factor associated with positive serology was the place of origin, having a higher risk for those living in the district of Huancayo and Chilca compared to El Tambo (p < 0.05).

在现实生活中配电网不可避免会发生供电中断，虽然这种可能性可以降低到最低程度，但是在许多情况下仍是不可避免的，尤其是在恶劣的天气和事故的情况下。狂风会让大树倒向架空线，吹断电线杆或是吹断架空线，但有一点是肯定的，除非有人去替换或抢修这些设备，否则供电中断会持续下去。修复的速度和效率在很大程度上有赖于决策支持系统的性能和配电网调度的辅助工具。

研究目的在于优化Ti0.8-0.9V0.2-0.1二元合金的相结构成分、微观组织和储氢性能。该合金主要用于从含有大量一氧化碳的高温气态混合物中吸收氢气。Ti0.8-0.9V0.2-0.1合金中的α-(HCP)和β-(BCC)相在纯氢气中基于氢化作用,形成单相FCC结构的氢化物,此过程与合金的化学成分无关。同步辐射X射线衍射的原位分析表明,在含有氢气和10%一氧化碳的混合气体中,只有β相转变成相应的氢化物。快速凝固(RS)处理细化了Ti0.8V0.2和Ti0.9V0.1合金的晶粒组织,而且,快速凝固处理增加了Ti0.9V0.1合金中的β相,其所占比例是普通熔铸条件下的两倍。扫描电子显微镜(SEM)分析表明,Ti0.9V0.1合金含有片状组织,层片的厚度约为300nm。热脱附谱(TDS)显示,微观组织的细化可以加快氢脱附的动力学过程。

Plant growth promotion indole-3-acetic acid (IAA) is the most abundant natural auxin that plays diverse roles in plant growth, development and plant immunity. Perturbing auxin homeostasis appears to be a common virulence mechanism, as many pathogens can synthesize auxin-like molecules. In other hand, the addition of plant growth promotion rhizobacteria (PGPR) that are able to produce auxins promotes plant growth and provides protection against pathogens. Techniques as high performance liquid chromatography (HPLC) and gas chromatography (GC) are used to quantify auxins produced by microorganism and plants at high precision and sensitivity, even though those techniques are expensive and require a big number of solvents. For these reasons, the aim of the present study was to develop a fast microplate technique for auxin detection, in Bacillus subtilis strains using salkowski reagent. For auxin quantification, calibration curves were done with alcohol, landy medium and water and the R2 were calculated. The microplate techniques were able to quantify auxin production by B. subtillis stains.
