This paper presents a study on the effects of radiation from electronic equipment in hospitals. This study was performed in Argentinean, Colombian and Spanish hospitals. The work consists of two parts: a survey to determine the hospital personnel’s knowledge of the problem and a technical part consisting of a measurements campaign to determine the levels of radiated electrical and magnetic fields in several hospitals due to the presence of electromagnetic interferences, such as the use of mobile phones. The study of this problem has been of special interest in countries such as the USA and Canada, and this paper attempts to convey the necessity of creating regulations that can be applied to the hospitals of the countries analyzed. More than fifty hospitals were studied in these three countries, considering the following aspects: the hospital personnel’s awareness of the problem, whether the hospitals have performed previous studies of this type, the appearance of problems in medical equipment due to this interference, the origin of the interference, and the failures that have appeared in computers due to electromagnetic interference. The results show that, most hospitals have a lack of knowledge regarding this issue and that field levels above those allowed by international regulations are present. Therefore, a regulation must be established to avoid the problem.

Postcopulatory sexual selection through sperm competition may be an important evolutionary force affecting many reproductive traits, including sperm morphometrics. Environmental factors such as pollutants, pesticides, and climate change may affect different sperm traits, and thus reproduction, in sensitive bird species. Many sperm-handling processes used in assisted reproductive techniques may also affect the size of sperm cells. The accurately measured dimensions of sperm cell structures （especially the head） can thus be used as indicators of environmental influences, in improving our understanding of reproductive and evolutionary strategies, and for optimizing assisted reproductive techniques （e.g., sperm cryopreservation） for use with birds. Computer-assisted sperm morphometry analysis （CASA-Morph） provides an accurate and reliable method for assessing sperm morphometry, reducing the problem of subjectivity associated with human visual assessment. Computerized systems have been standardized for use with semen from different mammalian species. Avian spermatozoa, however, are filiform, limiting their analysis with such systems, which were developed to examine the approximately spherical heads of mammalian sperm cells. To help overcome this, the standardization of staining techniques to be used in compute^-assessed light microscopical methods is a priority. The present review discusses these points and describes the sperm morphometric characteristics of several wild and domestic bird species.

Gnaphalium oxyphyllum DC is a medicinal plant whose common uses by Mexican people include the treatment of cancer. The toxicity of the aqueous and organic fractions as well as the aqueous decoction of G. oxyphyllum var. natalie F. J. Espinosa were assessed on three human cancer cell lines as well as in blood cells in healthy human lymphocyte cultures. Cytotoxic activity was assessed by the Sulforhodamine B method on HeLa （human cervical carcinoma）, T47D （human breast carcinoma） and 22Rvl （human prostate carcinoma cancer）. Colchicine was used as positive control. The decoction was also tested on lymphocytes from healthy donors through the mitotic index as biomarker. We used whole blood for these cultures and estimated the effect of the extract on platelets, leukocytes and erythrocytes. The aqueous decoction was cytotoxic （EDs0 〈 20 μg/mL） on the three cancer cell lines. The mitotic index in the exposed lymphocyte cultures did not significantly differ from the control nor the blood counts showed any difference between the experimental and control cultures. These results prove that the toxic effect of the aqueous decoction of G. oxyphyllum var. natalie is specific for cancer cell lines.

This work presents an analysis for the rural vernacular dwelling （Culata Yovai）, sited in the South America Guarani region, basin of Paraguay and Paraná rivers. Outdoor climate has conducted man to build along the time a habitat climatic responsive. Nowadays, studies in progress try to show how this vernacular typology can support new low-income house designs. The intent is to guarantee for new projects the socio-cultural image that people, coming from countryside to live in city outskirts, are accostumed. Also, to provide material improvements and functional adequation for a quality and healthiness. Natural ventilation is the main bioclimatic strategy during summer for thermal comfort, which influences the house characteristics. This is proven by calculation, and simulation with the CFX-ANSYS software. Thus, the analysis performed shows the real possibity to reconcile bioclimatism with the symbolic-cultural value represented by this vernacular architecture form. It is hopped that this study can be considered as a methodological contributition for new sustainable projects （materials, technics and services） of low-incoming houses in this Latin American region.

阿达伯托·奥尔蒂斯是厄瓜多尔最伟大的作家之一,他的作品也是拉丁美洲非裔西班牙文学的杰出代表。作为黑白混血儿,他在两种文化和身份之间成长,切身体会了种族主义和阶级歧视。在写作中,他重现了厄瓜多尔的黑人性及其演变,特别是他的小说《朱云戈》。该小说获得了1942年厄瓜多尔“国家最佳小说奖”,讲述了大约三十年来非裔厄瓜多尔人的生活以及其与不同种族的关系。本文运用跨文化交际批评理论,分析了小说《朱云戈》中的权力关系如何影响跨文化交流以及非裔厄瓜多尔黑人性的建构、觉醒和解读。基于此,本文提出厄瓜多尔黑人性是一个长期的文化适应、转型和丰富的过程,是跨文化接触受到权力的种族、政治和社会结构影响的结果。本文还认为,权力差异导致了从属关系、种族歧视和社会不公,厄瓜多尔黑人性是对此的一种抵制。该论文得出的结论是,厄瓜多尔黑人性是一种极为复杂的文化建构,它来自受权力结构影响的跨文化人际交往中,原始非洲文化被修改的过程。最后本论文认为,非裔厄瓜多尔人通过保护非洲遗产,珍重并维护了他们的黑人性。
