The dried beef is a food traditionally eaten by Northeastern and has an extensive trade in the city of Natal-RN. It is usually produced in an empirical manner, without any standardization in production. Characterized as partially dehydrated meat product, so that the activity of water present is not sufficient to prevent microbial growth, degradation or the production of microbial toxins. The guarantee that the market dried beef is to provide a quality product hygienic, microbiological, physicochemical and sensory stable and adequate for the safety and consumer satisfaction, which has been increasingly attracted to food with natural preservatives. Thus, the meat industries are replacing the current seasonings and natural preservatives for similar, with it without affecting the shelf life of products. Lactic acid has been used to meet these requirements. In this sense, this study aimed to evaluate the effect of lactic acid on the physico-chemical, microbiological and sensory, besides knowing the consumer profile of dried meat of the City of Natal / RN. The results demonstrated that the use of lactic acid in concentrations of 1% and 2% during the processing of dried meat, had statistically significant effect (p < 0.05) on the physico-chemical (pH and water activity) and consequently reduced the microbial count does not alter the taste of the new product developed. Regarding the results on the consumer profile, it was found that the majority of respondents (71.75%) did not observe the presence of the stamp of the Federal Inspection Service (SIF) to buy this meat food that 81.55% of consumers check the hygiene conditions of the site and handlers, however, a large proportion of respondents not concerned with the guarantee of origin of typical regional products featuring a hazard to food safety for consumers of the city of Natal-RN

OBJETIVO: Verificar a influência da utilização da fisioterapia complexa descongestiva associada à dietoterapia com triglicerídeos de cadeia média (TCM) como forma de intervenção no linfedema de membro superior (MS). MÉTODOS: Para a avaliação do linfedema, foram utilizadas cirtometria, volumetria, pregas cutâneas e quantidade de água corporal total. A Escala Visual Análoga (EVA) foi utilizada para avaliar as sensações de desconforto, peso e dor no MS. Participaram deste estudo dez mulheres mastectomizadas com linfedema de MS homolateral à cirurgia, com idade média de 65,9 ± 10,4 anos e índice de massa corpórea (IMC) de 26,8 ± 3,0kg/m² que, após avaliação nutricional, foram divididas aleatoriamente em dois grupos: Grupo Controle (n= 5), submetido ao tratamento fisioterapêutico constando da terapia complexa descongestiva (massagem clássica, drenagem linfática manual, bandagem compressiva e cuidados com a pele) três vezes na semana, durante quatro semanas; Grupo TCM (n= 5), submetido ao mesmo protocolo fisioterapêutico somado ao tratamento dietético diário com ingestão de TCM, por quatro semanas. RESULTADOS: Ao final da intervenção, a análise da cirtometria e da volumetria mostraram diferenças significativas entre os grupos (< 0,05), com maior redução do linfedema no Grupo TCM. Não houve diferença significativa nos valores das pregas cutâneas e da quantidade de água corporal total. A sensação de peso no membro superior, antes e após a intervenção, foi significativamente menor (< 0,05) no Grupo TCM. CONCLUSÕES: O tratamento fisioterapêutico somado à dietoterapia com ingestão de TCM em mulheres portadoras de linfedema de MS pós-cirurgia e tratamento de câncer de mama foi efetivo na involução desta condição.

The objective of this study was to evaluate the quality of housing and the physical and chemical characteristics of meat from sheep raised on pasture Brachiaria brizantha and Panicum maximum. The experiment was conducted in the physical area of the Study Group on Forage (GEFOR), located in the Academic Unit Specialized in Agricultural Sciences - Federal University of Rio Grande do Norte - UFRN in Macaíba, RN, Brazil. We used 32 lambs SPRD, obtained from herds in the state, with liveweight (LW) of 24.5 kg were assigned randomly to four treatments consisting of tropical grasses, two cultivars of Brachiaria brizantha, Marandu and Piatã, and two of Panicum maximum, Aruana and Massai. The experimental area was 2.88 ha, divided into 4 paddocks of 0.72 ha, where each picket consisted of a farm and was divided into six plots of 0.12 ha, where the animals remained under rotational grazing. The period of adaptation to the pickets was seven days. At the beginning of the experiment the animals were weighed, identified with plastic earrings and necklaces colored according to the treatment, and treated against. The lambs were loose in the paddock at 8 am and collected at 16 hours, which returned to collective pens. During the time of grazing animals had free access to mineral supplement with monensin Ovinofós ® and water. Before entering the paddocks of pasture were sampled to characterize the chemical composition. Every seven days occurred at weighing, with fasting, to monitor the weight development. Cultivars Marandu, Aruana, Piatã and Massai were grazed for 133, 129, 143 and 142 days, respectively, until the lambs reach slaughter weight. Arriving at 32 kg lambs were evaluated subjectively for body condition score by, passed through fasting period, diet and water for 16 hours were slaughtered. Measurements were made in the inner and outer casings in addition to subjective evaluations regarding muscling, finish and quantity of pelvic-renal fat, then each was divided longitudinally into two half-carcases and cuts were made in the commercial left half, and after heavy calculated their income. Between the 12th and 13th thoracic vertebrae, was performed a cut to expose the cross section of the Longissimus dorsi, which was drawn on the rib eye area (REA) in transparent film. Fat thickness and extent of AOL GR were determined using a caliper. A tissue composition was determined by dissection of the legs. Analyzes were performed physical (color, cooking loss and shear force) and chemical composition of meat (moisture, ash, protein and lipids) in Longissimus dorsi muscle. Grazing tropical grass Brachiaria brizantha cvs. Marandu and Piatã and Panicum maximum cvs. Aruana and Massai can be used for lambs SRPD in the rainy season, because not alter the physico-chemical and chemical composition of meat

Avaliaram-se a qualidade física do músculo Longissimus lumborum de ovelhas de descarte da raça Santa Inês, abatidas em diferentes estágios fisiológicos, a cor da gordura subcutânea desse músculo e as possíveis correlações entre as variáveis de qualidade da carne. Utilizaram-se 21 ovelhas, distribuídas nos seguintes tratamentos: T1= ovelhas que permaneceram por 60 dias em lactação com seus respectivos cordeiros e abatidas um dia após o desmame das crias; T2= ovelhas que permaneceram por 60 dias em lactação com seus respectivos cordeiros e mais um período aproximado de 30 dias sem os cordeiros e posteriormente abatidas; e T3= ovelhas que não pariram durante o ano. A cor da carne e da gordura subcutânea não foram influenciadas pelo estágios fisiológico dos animais no momento do abate, com exceção da luminosidade da carne (T1= 41,13; T2= 37,56 e T3= 38,12 L*). A qualidade física da carne apresentou pouca variação entre os tratamentos, porém a força de cisalhamento (T1= 4,08; T2=2,86 e T3=2,35 kgf/cm²) e as perdas por cocção (T1=31,97; T2=35,70 e T3= 31,91 %) da carne diferiram entre os tratamentos. Não se observou alta correlação entre a maioria das características avaliadas.

Estudaram-se a composição centesimal do músculo Longissimuslumborum e a aceitação sensorial do músculo Longissimus thoracis, provenientes de ovelhas de descarte da raça Santa Inês, abatidas em distintos estágios fisiológicos. Foram utilizadas 21 ovelhas, distribuídas nos seguintes grupos: OL = ovelhas que permaneceram por 60 dias em lactação com seus respectivos cordeiros e que foram abatidas um dia após o desmame deles; OSC = ovelhas que permaneceram por 60 dias em lactação com seus respectivos cordeiros e mais um período aproximado de 30 dias sem os cordeiros e que, posteriormente, foram abatidas; e ONP = ovelhas que não pariram durante o ano. Os teores de proteína e de cinzas da carne ovina foram semelhantes entre os grupos experimentais, e os valores de umidade e de gordura da carne diferiram entre os grupos. Não houve diferença significativa na aceitação sensorial da carne, segundo os grupos. Concluiu-se que o abate de ovelhas de descarte em diferentes estágios fisiológicos promove alteração na composição centesimal, quanto ao teor de gordura e de umidade da carne, e que não há diferença da aceitação sensorial da carne, de acordo com os grupos experimentais.

This master s dissertation deals with motivation and the meaning of work amongst bank employees. This is done considering a cognitive perception. Work is understood here under a social and subjective comprehension, once it deals with significance attribution. Motivation is the process that rules choice of the different possibilities of individual behavior, all of which according to the Expectation Theory. This study aims to analyze the implications of the productive restructure, since it is related to technological innovation, organizational changes and management, in motivation and work significance. Thus, the objective of the research is to verify motivational differences and the meaning of work amongst bank employees. This is done in two distinct moments of the productive restructure of bank employees in Natal-RN. The research is divided in two parts. In the first one, changes that occurred in banks between 1999 until 2005 were identified by the means of interviews with 7 bank managers. The analyzed perspective was training intensifying, quality emphasis of customer attendance, the use of automation/technology, staff stabilization, change in staff profile, work intensification, etc. In the second study the Inventory of Motivation and Work Meaning was applied. Thus, questions related to work focus, social demographic data, in 187 bank employees were dealt with. The collected data was compared to data from previous work. It was observed that productive restructure has a reflection in the meaning of work increasing self-expression, economical reward, and responsibility in work conditions. All of the item mention beforehand maintain the level of inhumanness and consummation and respond as being the characteristics of the real work environment. On the other hand, bank employees value less justice, self-expression and more the survival perspective, implying instrumental values to work. As for motivation, it is increased among bank employees. These employees have greater expectations that their work produce results since they believe in their interference in work results

The purpose of this study was investigate the sexual division of the work in a chain of fast food, in Natal, RN. These aspects were analyzed with the ways of organization of the work, being made a case study. The main objective of this survey was to analyze the influence of gender relations in the insertion of men and women in the job market and to analyze the question of feminine submission in the professional world. These questions were analyzed considering the current period of the worldwide capitalism, from the characteristics of productive process and the growth of the service sectors. The research was made with a group of workers on the production sectors; attendance, management and human resources at restfood store, where six clerks were interviewed. Through our research, it is possible to perceive the permanence of the sexual division at the job in the interior of the productive processes at Restfood, that puts the woman in a subordinate position in relation to the man. This result can be confirmed if we considerate that the women, on this chain of food, occupy in first place the function of waitress and on this, trere s no functional progression, while her workmates (the men) for occupying other functions can progress inside the company. It was also evidenced that in a context of globalization of the capital, deregulation and disrespect of labor laws, the capital acts without any respect to workers. That was what we observed at the interviewer speech; the scarcity of the conditions of work and the constant disrespect of the labor laws. This way, we could evidence that the scarcity of work conditions hit men and women, but it has a crueler face with the women, and this one reproduces itself, day by day in the process of social reproduction, through family life, insertion in the world of the work, information and received social education. So, the capital explores all of them, but the gender relations create to the capital, the possibility of a different degree of exploration, becoming this way, the women main victims herself

O objetivo do artigo é tratar das mutações sociais que ocorrem no mundo do trabalho a partir da era neoliberal no Brasil. Examina-se a precarização do trabalho como sendo elemento compositivo do novo metabolismo social que emerge com a reestruturação produtiva do capital e a constituição do Estado neoliberal. Apresenta-se como bases objetivas da precarização do trabalho, a intensificação (e ampliação) da exploração (e espoliação) da força de trabalho, o desmonte de coletivos de trabalho e de resistência sindical-corporativa; assim como a fragmentação social nas cidades em virtude do crescimento exacerbado do desemprego em massa.

In this work, we studied the strong consistency for a class of estimates for a transition density of a Markov chain with general state space E ⊂ Rd. The strong ergodicity of the estimates for the density transition is obtained from the strong consistency of the kernel estimates for both the marginal density p(:) of the chain and the joint density q(., .). In this work the Markov chain is supposed to be homogeneous, uniformly ergodic and possessing a stationary density p(.,.)
