Background The societal changes have created new necessities in terms of health care and of professionals with diverse skills. The institutions of higher education should promote the development of an entrepreneurial profile in students which may boost the exploration of new opportunities. Objectives: To identify the entrepreneurial profile in the students in higher education and its relationship to some personal characteristics and training. Methods Correlational quantitative study, accomplished with 1,604 students from 18 institutions of polytechnic Institutes of Portugal. The collection of data occurred between July and November/2015. The Carland Entrepreneurship Index (CEI) entrepreneurial skills questionnaire was applied, along with the acquisition of socio-demographic variables of the students. Data was analysed with the SPSS 23.0. The study followed the ethical requirements. Results The (CEI) application, allowed us to note that 75.7 % of the students presented an entrepreneurial profile, 20.8 % a Micro entrepreneurial profile and 3.4 % a Macro entrepreneurial. Additionally, we verified that older students (r = 0.193, p < = 0.000), of the male gender (Female = 0.55; Male, M= 0.580 p < 0.000), that had already worked or would like to work for others, showed the greatest entrepreneurial potential (Yes M= 0.60; No 0.54; p < 0.000), along with those who participated in entrepreneurial contents during their training (Did not participate M= 0.53; Participated 0.58; p < 0.000). Conclusions The entrepreneurial profile is related with some social demographic characteristics of the students; however, the educational institutions may have a preponderant role in the development of that profile, which may contribute to a greater contribution in the wellbeing of the populations.

OBJECTIVES: To study the effect of short-chain fatty-acids on atrophy and inflammation of excluded colonic segments before and after the development of diversion colitis. INTRODUCTION: Diversion colitis is a chronic inflammatory process affecting the dysfunctional colon, possibly evolving with mucous and blood discharge. The most favored hypotheses to explain its development is short-chain fatty-acid deficiency in the colon lumen. METHODS: Wistar rats were submitted to colostomy with distal colon exclusion. Two control groups (A1 and B1) received rectally administered physiological saline, whereas two experimental groups (A2 and B2) received rectally administered short-chain fatty-acids. The A groups were prophylactically treated (5th to 40th days postoperatively), whereas the B groups were therapeutically treated (after post-operative day 40). The mucosal thickness of the excluded colon was measured histologically. The inflammatory reaction of the mucosal lamina propria and the lymphoid tissue response were quantified through established scores. RESULTS: There was a significant thickness recovery of the colonic mucosa in group B2 animals (p = 0.0001), which also exhibited a significant reduction in the number of eosinophilic polymorphonuclear cells in the lamina propria (p = 0.0126) and in the intestinal lumen (p = 0.0256). Group A2 showed no mucosal thickness recovery and significant increases in the numbers of lymphocytes (p = 0.0006) and eosinophilic polymorphonuclear cells in the lamina propria of the mucosa (p = 0.0022). CONCLUSION: Therapeutic use of short-chain fatty-acids significantly reduced eosinophilic polymorphonuclear cell numbers in the intestinal wall and in the colonic lumen; it also reversed the atrophy of the colonic mucosa. Prophylactic use did not impede the development of mucosal atrophy

Natural nanoclays are of great interest particularly for the production of polymer-based nanocomposites. In this work, kaolinite clays from two natural deposits in the State of the Rio Grande do Norte and Paraiba were purified with thermal treatment and chemical treatments, and characterized. Front to the gotten data, had been proposals methodologies for elimination or reduction of coarse particle texts, oxide of iron and organic substance. These methodologies had consisted of the combination of operations with thermal treatments, carried through in electric oven, and acid chemical attacks with and hydrogen peroxide. The Analyzers Thermogravimetric was used to examine the thermal stability of the nanoclays. The analysis indicated weight losses at temperatures under 110 C and over the temperature range of 350 to 550 C. Based on the thermal analysis data, the samples were submitted to a thermal treatment at 500 C, for 8 h, to remove organic components. The X-ray diffraction patterns indicated that thermal treatment under 500 C affect the basic structure of kaolinite. The BET surface area measurements ranged from 32 to 38 m2/g for clay samples with thermal treatment and from 36 to 53 m2/g for chemically treated samples. Thus, although the thermal treatment increased the surface area, through the removal of organic components, the effect was not significant and chemical treatment is more efficient, not affect the basic structure of kaolinite, to improve particle dispersion. SEM analysis confirms that the clay is agglomerated forming micron-size particles

The object of this work is a fellowship of So Sebastião e Nossa Senhora do Rosrio in the city of Jardim do Serid (RN), that is, a black catholic fellowship on the serto potiguar. The devotion to Nossa Senhora do Rosrio, in colonial Brazil, organizes itself through black catholic men as fellowships. They blossomed in Brazil until the abolition, getting support from the Catholic church, from owners of slaves and from the population in general − unlike others afro-Brazilian religious expression. Today, these fellowships remain active, against the sentimental pessimism of the folklore studies, and they also have a highlight position in the calendar of many cities in Brazil, and in particular in Serid. The research s foothold is the apparent valorization of the fellowship by the local elite, attitude that hides asymmetric relationships between the group of negros do Rosrio and the local authorities, having as its consequence that the members occupy a subaltern position inside their own fellowship. This subalternity take place, mainly, in the public area, where the negros do Rosrio cannot represent themselves neither political nor discursively. To discuss this idea, it s done a brief historical of these catholic institutions as well as a description of the relationship between the negros do Rosrio and the elites of the city. Then, the phenomenon is analyzed as folklore and/or religion , under the perspective of many agents that participate in this process. In other moment, it is going to be presented how the group formulates their own representation of the history, of the devotional forms and of their own political-religious experiences. In this sense, an ethnography of the subalternity is understood as an analysis of the process that leads the negros do Rosrio to become a subaltern group. It s also outlined the perception that the group has of its own position, through an ethnography essay of the subaltern subject. The research, focused in the group of Rosrio, was done between August 2010 and January 2012 and includes other agents (like treasurers, priests and intellectuals). Besides that, as a methodological complement, there are documental research, photography, as well as shoots of the party days and public presentation

The use of raw materials from renewable sources for production of materials has been the subject of several studies and researches, because of its potential to substitute petrochemical-based materials. The addition of natural fibers to polymers represents an alternative in the partial or total replacement of glass fibers in composites. In this work, carnauba leaf fibers were used in the production of biodegradable composites with polyhydroxybutyrate (PHB) matrix. To improve the interfacial properties fiber / matrix were studied four chemical treatments to the fibers..The effect of the different chemical treatments on the morphological, physical, chemical and mechanical properties of the fibers and composites were investigated by scanning electron microscopy (SEM), infrared spectroscopy, X-ray diffraction, tensile and flexural tests, dynamic mechanical analysis (DMA), thermogravimetry (TGA) and diferential scanning calorimetry (DSC). The results of tensile tests indicated an increase in tensile strength of the composites after the chemical treatment of the fibers, with best results for the hydrogen peroxide treated fibers, even though the tensile strength of fibers was slightly reduced. This suggests a better interaction fiber/matrix which was also observed by SEM fractographs. The glass transition temperature (Tg) was reduced for all composites compared to the pure polymer which can be attributed to the absorption of solvents, moisture and other low molecular weight molecules by the fibers

This work aims at obtaining nanoparticles of iron oxide, the magnetite one (Fe3O4), via synthesis by thermal decomposition through polyol. Thus, two routes were evaluated: a simple decomposition route assisted by reflux and a hydrothermal route both without synthetic air atmosphere using a synthesis temperature of 260C. In this work observed the influence of the observe of surfactants which are generally applied in the synthesis of iron oxide nanoparticles decreasing cluster areas. Further, was observed pure magnetite phase without secondary phases generally found in the iron oxide synthesis, a better control of crystallite size, morphology, crystal structure and magnetic behavior. Finally, the introduction of hydroxyl groups on the nanoparticles surface was analyzed besides its employment in the polymer production with OH radicals. The obtained materials were characterized by XRD, DLS, VSM, TEM, TG and DSC analyses. The results for the magnetite obtainment with a particle size greater than 5 nm and smaller than 11 nm, well defined morphology and good magnetic properties with superparamagnetic behavior. The reflux synthesis was more efficient in the deposition of the hydroxyl groups on the nanoparticles surface

Nowadays, composite resins are the direct restorative materials more important in dental clinical performance, due to their versatility and aesthetic excellence. Bis-GMA (2,2-bis[4(2-hydroxy-3-metacryloxypropoxy)phenil]propane) is the base monomer more frequently used in restorative composite resins. However, this monomer presents some disadvantages, such as high viscosity and two aromatic rings in its structure that can promote allergic reactions to the humans. In this work, the main purpose was to synthesize new monomers from glycidyl methacrylate to use in dental restorative materials. Structural characterization of the monomers was carried out through FTIR and NMR 1H, and eight composites were produced from the new monomers, by addition of silane-treated alumino silicate particles (inorganic filler) and a photocuring system (camphorquinone and ethyl 4-dimethylaminebenzoate). The composites were analyzed by environmental scanning electronic microscopy and the water sorption and solubility, compressive strength and elastic modulus were determined. A commercial composite resin [Z100 (3M)] was used to comparison effect. The new composites presented general characteristics similar to the commercial ones; however, they didn t present the properties expected. This behavior was attributed to the lower degree of monomer reaction and to the granulometry and size distribution of the mineral filler in the polymeric matrix

O Movimento Associativo teve o seu inicio em Portugal no final do sculo XIX inicio do sculo XX, mas com um desenvolvimento mais acentuado aps o 25 de Abril de 1974, onde o pas saiu do regime do Estado Novo, dando ao povo portugus liberdade de livremente se expressar. Isto, levou ao aparecimento de novas associaes desportivas de forma a fomentar o desporto nacional, dando a hiptese de milhares de portugueses ter uma pratica desportiva de forma gratuita e regular, que at ento era quase um beneficio da classe social alta. Ao longo do desenvolvimento do associativismo, varias mudanas se sentiram, no final da dcada de 90 e principio do novo milnio comeou a enaltecer a "crise do associativismo, que segundo vrios autores e aqui referimos Melo de Carvalho, A. o associativismo desportivo comeou a sofrer da mercantilizao desenfreada que vem a caracterizar a sociedade, e a perder as suas origens, o seu propsito inicial, e apresentar dificuldades e procurar o apoio do estado, do poder local, para resolver os seus problemas. Neste mbito que desenvolvemos este trabalho, procurando no interior das associaes do concelho de Portalegre as principais causas da crise. Na metodologia utilizamos uma entrevista semiestruturada a 25 associaes, na pessoa do presidente ou responsvel, que esto includas no Programa de Apoio ao Associativismo Desportivo (PAAD) da Cmara Municipal de Portalegre. Como principais concluses, encontrmos: Falta de empreendedorismo apesar de uma grande parte das associaes serem jovens. Os dirigentes no so pessoas idosas ou com dfices de formao acadmica. Mas notasse falta de formao especifica do que a gesto do desporto, de como se desenvolve o desporto. O trabalho efectuado nas associaes muito realizado pela "carolice" dos "carolas" (dirigentes, principalmente s pelo presidente ou um responsvel) No realizam na sua generalidade planificao com vista o futuro e desenvolvimento da associao e do desporto.
