The Universidade Católica de Pernambuco is a private and non-profit Catholic university, located in Recife, the capital of the State of Pernambuco. It is one of the largest and most prestigious Brazilian universities. It is maintained by the Society of Jesus.The Catholic University of Pernambuco, created September 27, 1951 and recognized by the Federal Government through Decree 30,417 of January 18, 1952, originated from the first Catholic school in the region, the College of Philosophy, science and Letters Manoel da Nóbrega, founded in 1943 by the Jesuit Province of the Northeast. In its development, the University met incorporation, aggregation or creation of Colleges, Institutes or School, to implement in 1974 the university reform, advocated by law, adopting the model homogeneous ternary Rectory, Centres and Departments. The Unicap today constitutes an educational complex, which offers, for a community of about 15,000 students, first-degree courses to graduate "in the strict sense." In the area of graduate students enroll in several courses, some 50,000 graduates of the institution over the years of uninterrupted activity.The Central Library Aloísio M. de Carvalho, SJ is a supplementary organ subordinate to the Rectory. Aims to provide basic information support to teaching, research and extension. It has, on average, 15,000 registered users, including undergraduates, graduate, faculty and technical administrative personnel and alumni. Meets, on average, to 400,000 visits per year to the Library and performs more than 700,000 home loans per year and has an average frequency of 3,500 readers per day.The collection of free access to over 449,000 copies is composed of several collections, distributed on various floors of the Library, covering the areas of Social and Applied science, Humanities, Linguistics, Literature and Arts, Exact and Earth, Health, Biological, and Agricultural Engineering. All works can be searched via the Internet.In 2010, the MEC took note 4, with 5 being the highest score. According to table of the MEC, footnote 4 is above the level required for institutions of higher education. "It is a seal of quality. Attests that we are a real university, one of the best in the country, "defined the rector, Pedro Rubens. This was the first time the University went through the process of institutional evaluation of MEC. The evaluators visited the university premises . And heard leaders, teachers, students and staff.According to the MEC's system of proportional values, the most important criterion is "The policy for teaching , research, extension," which won the Unicap footnote 4. Other highlights of the assessment for the university was the policy of incentives for graduates , the approval of trained law course in the examination of the Bar Association of Brazil , 33 Unicap research groups registered with the National Council for Scientific and Technological Development and the program of scholarships for teachers and employees themselves.The Student Exchange Program offered by Unicap aims at giving students an academic experience, for one or two semesters in an IES national or international level, through agreements of mutual cooperation in education. This program has its origin in the directives of AUSJAL, Association of Universities entrusted to the Society of Jesus in Latin America, which proposes the integration of students from Latin American Jesuit higher education institutions as complementary modality for their training. On the other hand, Unicap receives foreign students of IESs wishing to conduct graduate study for one or two periods. Wikipedia.

Some yeasts are preferred to bacteria as sources for biosurfactants, mainly due to their GRAS status for environmental and health safety reasons. This chapter thus focuses on the production of biosurfactants by some yeast cultures using renewable resources like fatty wastes from household and vegetable oil refineries as major substrates. The chapter also emphasizes on the importance of the application of response surface methodology and artificial neural network techniques for the optimization of biosurfactant production by yeasts. © 2010 Landes Bioscience and Springer Science+Business Media.

Ths paper discusses the formation of counselors in HIV/AIDS, requirement of the Ministry of Health for health professionals to develop this practice among users seeking HIV testing. To addressing training is strategic to qualify their practice, building more efficient and effective responses to AIDS. Analyses of manuals of the ministry and interviews with advisors, conducted within a research thesis (in progress), subsidize the discussion. From the analyses of textbooks are highlighted the concept of subjectivity-identity, as a relentless brand defined by the user's sexual practices, and prescriptive and directive trend in recommendations for professionals. From the analysis of interviews, we highlight the identified advising ways - education and respect. These findings add to the reflections on the advice - treated as health device and non material production in the context of reflections on the world of labor in capitalist societies. It is suggested that counseling tends to be captured by the commodity perspective, the close association between scientific and economic rationality in the health field. This arrangement is supported by the still hegemonic ideology in biomedical health practices. To escape this direction, it is suggested critical positioning for counselors in conducting their work, avoiding directive and protocol posture. The counseling-relationship is presented as an alternative advisory way by using lightweight technologies, aligned relationships, respect for differences and the role of the user in his own care. Finally, propositions (principles and contents) are presented to conduct training processes towards relationship-advice. Source

Background: The practice of electronic games has been disconnected from a merely playful character, as its excessive use may be considered as a new psychiatric disorder. Objective: To accomplish a review of the scientific literature concerning this possible dependence, addressing its main characteristics, worldwide prevalence and the possibility of comorbidities, and to evaluate the existence of treatment procedures based on cognitive behavioral therapy. Method: The research was conducted for articles published between 2001 and June 2011, using the PubMed, BVS, Lilacs and SciELO databases. Results: There is no consensus whether the electronic game dependence is affiliated with the impulse control disorder group or chemical dependence. But it is known that the worldwide prevalence of this dependence has an average of 3%, with male predominance, and that there exist comorbidities of electronic game and chemical dependence. The cognitive behavioral therapy is already used as a possible treatment with effective short-term results. Discussion: Despite dependence on electronic games is not considered as a specific diagnosis, this new phenomenon should be discussed and deepened in the scientific literature, seeking, in parallel, an efficient model of psychotherapeutic and pharmacological treatment.

Colloids and Surfaces B: Biointerfaces

Biosurfactants are surface-active agents of microbial origin, and have a property of lowering the interfacial tension between two liquids. They act on the interface and are amphiphathic molecules; in with both hydrophilic and hydrophobic portions are present in the same molecule. However, the economics of producing biosurfactant has limited its commercial applications, and the costs can be reduced using cheap substrates or industrial waste. The present study showed the biosurfactant production using corn steep liquor and palm oil as carbon and nitrogen sources for reduction the costs of production. The biosurfactant production by Geobacillus stearothermophilus UCP 986 was carried out using optimized culture medium constituted by palm oil (7.5%) and corn steep liquor (4.5%) using Bioflo fermentor, at temperature of 45°C, during 32h and agitation of 300rpm. The biosurfactant showed a reduction of the water surface tension of 72-31mN/m and interfacial tension of 0.3mN/m. The biosurfactant was obtained from the net metabolic liquid by acetone precipitation corresponding to the yield of 2.3g/L. The isolate biosurfactant showed a CMC of 2.5% and non-ionic profile. The best emulsification index (E24) obtained was 87% using motor oil burned. The biosurfactant solution (2.5%) used in oil spreading test increases the viscosity of engine burning oil of 149.2% and 138.2% to vegetable fat post-frying, respectively. The gas chromatography-mass spectrometer indicated at 29.52min a molecular weight of 207Da and eight peaks by FT-IR identified the chemical structure of the biosurfactant produced by G. stearothermophilus. © 2012 .

Biosurfactant production by Candida glabrata was studied using vegetable fat waste as substrate. A factorial design was initially carried out to investigate the effects and interactions of waste, yeast extract and glucose on the surface tension after 144 h cultivation. Maximum surface tension reduction was achieved with vegetable fat waste at 5% and yeast extract at 0.2%. The biosurfactant containing cell-free broth retained its surface-active properties after incubation at high temperatures, at a wide range of pH values and salt concentrations. Comparison between three solvent systems for surfactant recovery showed that ethyl acetate extracted both crude extracellular and intracellular biosurfactant with high product recovery. The isolated extracellular biosurfactant showed a CMC of 1% and the surface tension at that point was 24 mN m-1. Preliminary chemical composition revealed the presence of carbohydrates, proteins and lipids. The application of the crude biosurfactant to a soil-water-hydrophobic contaminant system was investigated and the apparent critical micelle concentration was determined at 7% of the broth, although the best oil removal (92.6%) had been obtained with 10% of the cell-free broth. The cost of application of the biosurfactant in soils was estimated based on the cost of a commercial biosurfactant. © 2010 Springer Science+Business Media B.V. Source
