Abstract: The temperature control of the heterogeneous alkylation, where H 2SO 4 is used as catalyst, is discussed in this paper. The problem is to design a control function to stabilize temperature in face of uncertain kinetic model. The proposed controller, whose structure resembles a PI-controller, is based on energy balance. The resulting feedback controller is robust, leads to an acceptable performance, and computes the temperature of the coolant from the refrigeration section to the reactor. The effectiveness and robustness of the designed controller for computing the coolant temperature is tested by means of simulations in such a manner that we study the effects of: (i) load disturbances, (ii) model uncertainties and (iii) initial conditions for estimation values.

This paper reports on an evaluation of a specialization in qualitative health research from the student's perspective. The course was carried-out on four different occasions and its evaluation was a qualitative one. Approximately eighty health and social science professionals attended and evaluated the course. Triangulation methods were used for data gathering: an open-ended questionnaire, individual interviews, and participants' feed-back; a modified SWOT method was also used. Data was analyzed using content analysis. From the participants' point of view, the course allowed them to acquire knowledge on qualitative research approaches and methods and, to lesser extent, on how to write a research project. Participants encountered difficulties: lack of time, limited resources as well as lack of support. Several strategies are suggested for improving the course.",,,,,,"10.1590/S1414-32832008000300005",,,"http://hdl.handle.net/20.500.12104/44964","http://www.scopus.com/inward/record.url?eid=2-s2.0-55249113695&partnerID=40&md5=0aee89827f15eda16a93cf855ff762d0",,,,,,"26",,"Interface: Communication, Health, Education",,"515

Rocha-Olivares, A.",,"2013",,"The coral fauna of the Eastern Tropical Pacific (ETP) is depauperate and peripheral; hence, it has drawn attention to the factors allowing its survival. Here, we use a genetic seascape approach and ecological niche modeling to unravel the environmental factors correlating with the genetic variation of Porites panamensis, a hermatypic coral endemic to the ETP. Specifically, we test if levels of diversity and connectivity are higher among abundant than among depauperate populations, as expected by a geographically relaxed version of the Abundant Center Hypothesis (rel-ACH). Unlike the original ACH, referring to a geographical center of distribution of maximal abundance, the rel-ACH refers only to a center of maximum abundance, irrespective of its geographic position. The patterns of relative abundance of P. panamensis in the Mexican Pacific revealed that northern populations from Baja California represent its center of abundance; and southern depauperate populations along the continental margin are peripheral relative to it. Genetic patterns of diversity and structure of nuclear DNA sequences (ribosomal DNA and a single copy open reading frame) and five alloenzymatic loci partially agreed with rel-ACH predictions. We found higher diversity levels in peninsular populations and significant differentiation between peninsular and continental colonies. In addition, continental populations showed higher levels of differentiation and lower connectivity than peninsular populations in the absence of isolation by distance in each region. Some discrepancies with model expectations may relate to the influence of significant habitat discontinuities in the face of limited dispersal potential. Environmental data analyses and niche modeling allowed us to identify temperature, water clarity, and substrate availability as the main factors correlating with patterns of abundance, genetic diversity, and structure, which may hold the key to the survival of P. panamensis in the face of widespread environmental degradation.
