A SIMPLE METHOD FOR DETERMINING LOCATION OF FORAGING ANT NESTS USING LEAF-CUTTING ANTS AS A MODEL

In many situations, it is difficult to evaluate the location of nests of ants, especially in tropical systems, or to determine which trail system corresponds with which nest, as in the case of high-density populations of leaf-cutting ants, Atta spp. Fragments of colored drinking straws coated with an attractant, generally vegetable oil and/or a starchy carbohydrate, are carried by ants and following removal of the attractant are deposited in middens, allowing determination of the origin of foraging workers.

Adequações tecnológicas no beneficiamento do caranguejo-uçá Ucides cordatus (Linnaeus, 1763) desenvolvido na comunidade de Caratateua, município de Bragança, estado do Pará, Brasil

No Estado do Pará, o beneficiamento do caranguejo-uçá ocorre de forma totalmente artesanal, sendo o seu produto frequentemente associado a eventos de intoxicação alimentar. Neste trabalho o autor tem por finalidade propor adequações tecnológicas no processamento deste crustáceo desenvolvido na comunidade de Caratateua, município de Bragança/Pará. Foram realizadas excursões mensais à comunidade de abril/2008 a maio/2009 com aplicação de 120 entrevistas direcionadas aos principais atores sociais envolvidos na atividade, constando de aspectos econômicos, sociais e tecnológicos, além de análises laboratoriais (composição química e microbiologia), observações de campo e revisão de literatura. Constatou-se que a quantidade de caranguejo desembarcada e o tamanho médio dos indivíduos vêm diminuindo nos últimos anos. A captura é realizada exclusivamente por indivíduos do sexo masculino, sendo o gancho o principal apetrecho utilizado. O beneficiamento é praticado principalmente por mulheres e crianças, porém homens eventualmente também o fazem. Não há uma padronização do processamento e as condições higiênico-sanitárias dos locais de beneficiamento são na grande maioria das vezes inadequadas, podendo este ser realizado no interior da residência, em “puxadinhas” ou nos quintais, geralmente na presença de animais domésticos, insetos e sem a adequada assepsia de manipuladores, equipamentos e superfícies de contato. Desta forma, conclui-se que tal realidade é ocasionada principalmente pelo desordenamento da pescaria e falta de preocupação dos catadores quanto à qualidade do produto, sendo de fundamental importância a criação de uma legislação específica para a carne de caranguejo e a adoção de boas práticas de fabricação levando em consideração a realidade local visando agregação de valor ao produto e maior segurança alimentar aos consumidores.

Modo de vida na várzea: políticas sociais e nova ruralidade: estudo em uma localidade da Reserva de Desenvolvimento Sustentável Mamirauá

Esta dissertação é um estudo sobre as ações em torno do desenvolvimento sustentável e de políticas não agrícolas para as pequenas populações rurais, a partir dos anos 80 e 90. Com a interiorização das políticas, o Estado se torna mais presente nas regiões interioranas redimensionando o mundo rural e suas dinâmicas locais. Neste sentido, um novo rural emerge com as ações políticas que chegam às populações mais distantes expondo o modo de vida a novas situações. Este estudo objetivou analisar as mudanças na organização social e econômica dos moradores da localidade rural de Vila Alencar da Reserva de Desenvolvimento Sustentável Mamirauá (RDSM), no estado do Amazonas, decorrentes da criação de uma reserva de desenvolvimento sustentável (RDS) e das ações institucionalizadas por políticas de Estado. A análise teórica foi fundamentada na noção de habitus e do campo socioambiental da Reserva Mamirauá. Realizaram-se também análises entre as famílias a partir do tempo de união conjugal, com a finalidade de identificar as mudanças ocorridas entre duas gerações familiares. Constatou-se neste estudo que a organização familiar em Vila Alencar se desenvolve levando em consideração as práticas locais e também participam das ações intervencionistas através das políticas sociais por meio do Programa Bolsa Família, das aposentadorias rurais e das atividades em torno do manejo sustentável dos recursos naturais, que estão em sua maioria associadas ao manejo de ecoturismo, a exemplo, da prestação de serviços como guia turístico, auxiliar de cozinha, copeira e carpintaria para a pousada de ecoturismo da RDSM. A combinação de atividades agrícolas, nãoagrícolas e a complementação de renda por benefícios sociais assumem papel importante na composição da renda familiar, o que traz novas perspectivas à reprodução social. O estudo mostrou que as políticas de desenvolvimento sustentável bem como as políticas de benefícios sociais tornam favorável à organização familiar das localidades rurais as características de feições modernizadoras e atrativas do conforto urbano, sobretudo pela expectativa da compra de uma casa na cidade e de melhores condições de qualificação aos filhos para prosperarem em alguma profissão. Aos jovens são delegadas outras responsabilidades que não se inserem exclusivamente no contexto produtivo do trabalho familiar.

Avaliação dos resíduos sólidos gerados no Restaurante Universitário da UNESP de Rio Claro: uma análise do potencial de compostagem

A consequence of population growth is the increased generation of solid waste, which requires environmentally and economically viable suitable disposal sites. The scarcity of such sites makes necessary to adopt non-generation measures, reduction, reuse , recycling and treatment of solid waste before final disposal of waste. This paper presents the quantification and qualification of organic waste generated in each sector of the University Restaurant (UR) , by proposing indicators of waste generation per meal (index of waste) . Then, from the characterization of the waste management practices adopted internally, evaluates the potential deployment of the composting process for organic waste, with signaling for opportunities to improve waste management. The diagnosis of waste generation was made based on data collected during the period of 10 days. The waste were classified into 3 groups (organic, recyclable and waste) in each sector of the restaurant ( pre preparation , kitchen and tray return) . The results reveal that 33 % of the waste generated in the UR currently has the potential to be composted in a suitable place on campus. Every meal served generat approximately 124g of waste, of which 35g are organic waste of the pre preparation sector, 49g are remnants of food in the tray’s return and 40g are other kinds of waste, including recyclable and non recyclable. You can still get a higher percentage of compostable if the trays pre-wash is not performed with detergent and water. To minimize the generation of waste trays can be replaced by plates and skimmers and ladles can be replaced by smaller ones. The food exposed in the counter but not consumed, can be distributed to students after the restaurant is closed so this material would not be disposed in the garbage

Estudo das condições de preparo da merenda escolar em creches

Foods are susceptible to be contaminated with several etiologic agents, which can lead to the development of illnesses, triggered by pathogenic microorganisms or their toxins. Food prepared and improperly stored can be the diseases vehicle. This study aimed at evaluating the sanitary conditions in preparing free school meals in the nursery schools, located in a city of the state of São Paulo. This study was conducted by performing microbiological analyses of samples collected from hands of workers responsible for preparing food, and of the water samples used for cleansing and preparing foods. The kitchen physical, structural and cleaning conditions were assessed by means of a checklist. This study analyzed 31 samples from worker hands swab, and 21 samples of water collected from three school kitchens. This study pointed out that the food handlers training should be improved, and a peremptory control of the water used for food preparation purpose should be established. Also, this study showed that the evaluated schools maintain the respective kitchens in a good standard of conservation and cleanliness.

RB30-245 Water Supply and Sewage Disposal Systems for Farm Homes

When the well "goes dry" or when the windmill or pump breaks down, every one in the household immediately appreciates the value fo plenty of water. In other words, "You never miss the water until the well runs dry." Fortunately, in most sections of this state, plenty of pure water may be obtained by sinking wells of moderate depth, yet surprisingly few farm homes are supplied with running water in the kitchen even though the barn yards are equipped with hydrants and tanks. It is the purpose of this bulletin to present a number of water supply and sewage disposal systems which have been used in Nebraska and surrounding states and which add greatly to the comfort and convenience of the farm home.

The Influence of Schematic Knowledge on Contradictory versus Additive Misinformation: False Memory for Typical and Atypical Items

In the current study, we examined the influence of schema consistency on contradictory and additive misinformation. Sixty-four participants were shown a series of still photographs of common scenes (e.g., a kitchen), were later exposed to narratives containing misinformation, and were then tested on their memory of the photographic scenes. In addition, participants were asked to reflect on their phenomenological experience of remembering by giving remember/know responses. Participants reported greater false memory for schema-inconsistent items than schema-consistent items. The findings failed to replicate Roediger, Meade, and Bergman (2001). Explanations for the discrepant findings are discussed.

Archaeofacies Analysis: Using Depositional Attributes to Identify Anthropic Processes of Deposition in a Monumental Shell Mound of Santa Catarina State, Southern Brazil

In the coast of Santa Catarina State (southern Brazil), a large population of monumental shell mounds characterizes a highly dynamic coastal setting. In this paper, sedimentary facies analysis was adapted for description, sampling, and interpretation of shell mound complex and repetitive archaeostratigraphic successions. Archaeofacies identification in the field, according to depositional attributes, is tested by contrasting field description with multi-element chemical analyses, total carbon and nitrogen determinations, and micromorphological descriptions. Two vertical sequences at the black deposit of Jabuticabeira II shell mound were studied and preliminary results showed that: (1) depositional attributes are a reliable base for archaeofacies identification in the field, (2) the formation process of this site involved a sequence of anthropic depositional processes, where burned refuse was redeposited over the shell mound following a ritual construction pattern, and (3) the black deposit includes a double palimpsest that refers to provenance and meaning of mound construction material.

Hurdles at work: perceptions of hospital food handlers

Abstract Background Food handlers have a very important role in preventing food contamination during its preparation and distribution. This responsibility is even greater in hospitals, since a large number of patients have low immunity and consequently food contamination by pathogenic bacteria could be particularly harmful. Therefore, a good working environment and periodic training should be provided to food handlers by upper management. Methods This study is qualitative research by means of focus group and thematic content analysis methodologies to examine, in detail, the statements by food handlers working in the milk and specific-diet kitchens in a hospital to understand the problems they face in the workplace. Results We found that food handlers are aware of the role they play in restoring patients' health; they consider it important to offer a good-quality diet. However, according to their perceptions, a number of difficulties prevent them from reaching this aim. These include: upper management not prioritizing human and material resources to the dietetic services when making resource allocation decisions; a perception that upper management considers their work to be of lesser importance; delayed overtime payments; lack of periodic training; managers lacking administrative skills; insufficient dietitian staff assistants, leading to overwork, at the same time as there is an excess of dietitians; unhealthy environmental working conditions – high temperature, high humidity, loud and constant noise level, poor ventilation; lack of food, and kitchen utensils and equipment; and relationship conflicts with chief dieticians and co-workers. Conclusion From these findings, improvement in staff motivation could be achieved by considering non-financial incentives, such as improvement in working conditions and showing appreciation and respect through supervision, training and performance appraisal. Management action, such as investments in intermediary management so that managers have the capacity to provide supportive supervision, as well as better use of performance appraisal and access to training, may help overcome the identified problems.

Standard intracranial in vivo animal models of delayed cerebral vasospasm

Animal models provide a basis for clarifying the complex pathogenesis of delayed cerebral vasospasm (DCVS) and for screening of potential therapeutic approaches. Arbitrary use of experimental parameters in current models can lead to results of uncertain relevance. The aim of this work was to identify and analyze the most consistent and feasible models and their parameters for each animal.
