The paper discusses the results of a field study carried out in four cities in Mexico: Hermosillo, Mexicali, Merida and Colima, during the warmest seasons of 2006-2007. The survey is according to the adaptive approach of thermal comfort. The cities" climates are hot dry, hot sub-humid and hot humid. The respondents were inhabitants of low cost housings without air conditioning. The research was performed during warm seasons and according to ISO 10551. The measurements were processed by the common method of linear regression and also by alternative methods, useful for asymmetric climates. Individuals declared comfort at very high temperatures, either high or low humidity, therefore, the resulting neutral temperatures are higher than 30 ?C, except in Colima (28.8 ?C). The upper limits of comfort ranges achieved temperatures up to 35 ?C. The results suggest how great is the capacity of humans to adapt to conditions as extreme as those measured in the study.

AIM：To compare the effect of phacoemulsification on intraocular pressure（IOP）in patients with primary open angle glaucoma（POAG）and pseudoexfoliation glaucoma（PXG）.METHODS：A retrospective comparative case series conducted at the Glaucoma Department at the Association to Prevent Blindness in Mexico.The study enrolled consecutive patients having phacoemulsification with intraocular lens（IOL）implantation and a diagnosis of POAG or PXG.Data about IOP values and number of glaucoma medications used was collected at baseline,1,3,6 and12mo postoperatively.RESULTS：The study enrolled 88 patients（88 eyes）.After phacoemulsification,there was a statistically significant reduction in IOP values and glaucoma medications use compared to baseline in both POAG and PXG patients（P〈0.001）.In the POAG group,a 20%decrease in IOP values was evidenced,and a 56.5%reduction in the number of medications used at the one-year follow-up.The PXG group showed a 20.39%,and a 34.46%decrease in IOP and number of medications used,respectively.A significant difference in the meanΔIOP（postoperative changes in IOP）was evidenced between groups（P=0.005）.The reduction of the postsurgical IOP mean values in both groups,the POAG group showed a greater reduction in IOP values compared to the PXG group.CONCLUSION：In both types of glaucoma,phacoemulsification cataract surgery can result in a significant IOP reduction（20%）over a 12mo follow-up period.The number of medications used is also significantly reduced up to 12mo after surgery,especially in the PXG group.

Adaptive Thermal Comfort for Occupants of Low-Cost Dwellings in a Hot Dry Climate

引用

Journal of Civil Engineering and Architecture 2012年第3期6卷 356-363页

作者： Irene Marincic J. Manuel Ochoa M. Guadalupe Alpuche gabriel gomez-azpeitia Department of Architecture and Design University of Sonora Hermosillo 83000 Mexico Facuhy of Architecture and Design University of Colima Colima 28400 Mexico

Adaptive models are based on the observation that there are some actions that people can and actually do take to achieve thermal comfort. Studies regarding thermal comfort conditions in economical dwellings were carried out simultaneously in seven Mexican cities, corresponding to warm dry and warm humid climates. In this article, case studies of low-cost dwellings in the city of Hermosillo (in northwest Mexico), are presented and analyzed. Field surveys were carried out to obtain information about the physical characteristics of the dwellings and their occupants, as well as the indoor thermal environment. Neutral temperature was obtained from the applied survey. The high neutral temperature reveals the effect of inhabitants" adaptation mechanism to extreme climates. Occupant comfort votes as a function of indoor air temperatures were analyzed, and different characteristics such as age, size and gender were evaluated separately. The results show the variability of the neutral temperature and the tolerance to temperature changes, depending on the population"s specific characteristics. In many cases where the population does not have access to artificial acclimatization devices, the neutral temperature values for specific climates and people can inform architects when choosing the most suitable thermal strategies for building design.

Low pressure plasma polymer films were synthesized using pyrrole and allylamine monomers and adding iodine was used(or not)for the reaction in both cases.They were polymerized on glass substrates under the same reaction conditions.Polymerization of allylamine was also studied at different operating powers.These thin polymer films were used as culture surfaces for HepG2 cells,a cell line derived from a human hepatoma.The proliferation,differentiation and two-dimensional propagation until obtaining monolayer of the cells was studied on the different synthetized films and correlations were established between the conditions of synthesis,the physicochemical characteristics obtained and the performance as substrates for the cellular growth.
