O processo de formação profissional nos semi-internatos : a percepção do acadêmico de enfermagem da Universidade Federal do Pará, Brasil
Avaliou-se o processo de formação profissional nos semi-internatos do Curso de Graduação em Enfermagem da Universidade Federal do Pará, a partir da percepção dos discentes. Utilizou-se uma abordagem quali-quantitativa por meio de estudo de caso, com análise documental Projeto Pedagógico - PP e das ementas do semi-internato e construção de um instrumento atitudinal do Tipo Likert. Concluiu-se que as competências de atenção a saúde e comunicação, o trabalho docente, a relação docente/discente e a articulação teoria-prática têm uma percepção positiva entre os discentes. Contudo observa-se uma percepção mais crítica quanto à oferta de cenários de prática em diferentes níveis de atenção, aspecto de grande relevância para a formação profissional em saúde

Please use the published version in any citations.The final version of the article is available from Archaeopress via the link in this record.Researchers from the MARES Project visited Yemen in February 2009 in
order to investigate the building and use of traditional wooden boats (‘dhows’,
in English parlance) in the country. The survey covered the coastline from
Aden to Salif in the Red Sea, and visited centres of traditional dhow building
and use, including Ghureira, Mocha and Khokha. The project aimed to assess
the state of the industry, establish a vessel typology, understand construction
processes, learn about the use of these vessels, and compile a lexicon of
boatbuilding and nautical terms. This article offers the preliminary findings of
the survey, pending more comprehensive publication in the future. The survey
found that, in all locations visited, the building of new vessels had rapidly
diminished in the preceding decade, and had now all but ceased. The only
ongoing activity witnessed during the survey was repairs to existing wooden
craft. In formerly large boat-building centres, wooden boat-builders, mostly
elderly, have ceased work, while younger men were building fishing craft
using fibreglass – the material used in the great majority of vessels in Yemen
today. A preliminary typology of surviving vessel was established. The doubleended
cargo-carrying za<īmahs and zārūqs were recorded only as
2
abandoned hulks. Double-ended <obrīs and transom-sterned ‘large hūrīs’,
with their stern-quarter ‘fins’, continued to be used in small numbers for sein
fishing and transporting livestock. Again, most examples were abandoned.
Various forms of small log and plank hūrī ‘canoes’ were observed, few still in
use, while the log-raft ramas survives on the Red Sea coast. The terms used
for these vessel types form part of a linguistic survey of dhow activity in
Yemen.This research was conducted as part of the MARES Project, a three-year
programme investigating the maritime past and heritage of the Red Sea and
Arabian-Persian Gulf. MARES is based at the Institute of Arab and Islamic
Studies at the University of Exeter (http://projects.exeter.ac.uk/mares). The
programme is funded by the Golden Web Foundation, an educational charity
registered in the UK (www.goldenweb.org), to which our gratitude is due.

EXECUÇÃO ORÇAMENTÁRIA: UM ESTUDO SOBRE A INSCRIÇÃO DE RESTOS A PAGAR NAS UNIVERSIDADES FEDERAIS DO NORDESTE
A presente pesquisa tem como objetivo verificar se houve modificação na situação dos restos a pagar nas Universidades Federais do Nordeste com o advento do decreto nº 7654 de 23 de dezembro de 2011. Para tanto, analisou-se a execução orçamentária em catorze universidades de nordeste, por meio das informações disponibilizadas no site de Tribunal de Contas da União (TCU) e do Senado Federal (SIGA Brasil). O levantamento de dados foi feito através da pesquisa documental e a análise foi realizada por meio de software estatístico Statistical Package for Social Sciences (SPSS), utilizando-se dos testes de Shapiro-Wilk e Wilcoxon, media e desvio padrão, com 5% de significância. Conclui-se que não houve diferenças estatísticas entre o antes e o depois do decreto em relação ao percentual de restos a pagar sobre o montante empenhado pelas IFES (p=0,551). Contudo, em relação às despesas de capital, foram constatadas diferenças estatisticamente significantes entre o percentual médio empenhado/autorizado antes do decreto com o depois do decreto (p=0,006),ou seja, as IFES passaram a emprenhar menos depois do decreto, sendo estas as que mais contribuíram para inscrição de restos a pagar. Já quanto às despesas correntes, não houve diferenças estatisticamente significantes entre as IFES ante e depois do decreto. Ressalta-se ainda que houve um pequeno aumento em relação aos restos a pagar nas despesas com pessoal para as IFES com menos orçamento
Strain-controlled criticality governs the nonlinear mechanics of fibre networks
Disordered fibrous networks are ubiquitous in nature as major structural
components of living cells and tissues. The mechanical stability of networks
generally depends on the degree of connectivity: only when the average number
of connections between nodes exceeds the isostatic threshold are networks
stable (Maxwell, J. C., Philosophical Magazine 27, 294 (1864)). Upon increasing
the connectivity through this point, such networks undergo a mechanical phase
transition from a floppy to a rigid phase. However, even sub-isostatic networks
become rigid when subjected to sufficiently large deformations. To study this
strain-controlled transition, we perform a combination of computational
modeling of fibre networks and experiments on networks of type I collagen
fibers, which are crucial for the integrity of biological tissues. We show
theoretically that the development of rigidity is characterized by a
strain-controlled continuous phase transition with signatures of criticality.
Our experiments demonstrate mechanical properties consistent with our model,
including the predicted critical exponents. We show that the nonlinear
mechanics of collagen networks can be quantitatively captured by the
predictions of scaling theory for the strain-controlled critical behavior over
a wide range of network concentrations and strains up to failure of the
material
TEMPO QUE OS ESTUDANTES COM AUXÍLIO MORADIA NA UFPE LEVAM PARA SE FORMAR OU SE DESVINCULAR DA INSTITUIÇÃO
A assistência à moradia têm grande importância na vida dos alunos que não possuem condições financeiras para terem acesso à Universidade.O presente estudo procura estimar o tempo até se formar ou se desvincular para os estudantes da graduação com auxílio moradia (que residem ou residiram na residência estudantil na UFPE, ou ainda que apenas recebem o referido auxílio), a partir de algumas variáveis de interesse, tais como: tempo de residência, tempo de vínculo com a instituição e obtenção da titulação universitária, destacando-se as diferenças/semelhanças, por sexo e por área de conhecimento do curso. Os dados analisados se referem aos beneficiários do auxílio no período de 2005 a 2014. Através da aplicação das técnicas da análise de sobrevivência foi possível estimar o tempo mediano para o estudante ficar com auxílio moradia até se formar e também até ser desvinculado. Como resultado, pode-se identificar que alguns discentes mudam de curso durante o período do auxílio, como também, o tempo mediano do residente até se formar difere para área de exatas como também em relação ao sexo. O mesmo não aconteceu com o modelo de sobrevivência até o aluno se desvincular, visto que nem a área de estudo e nem o sexo apresentaram diferenças significativas nas curvas de sobrevivência
Complex nature of SNP genotype effects on gene expression in primary human leucocytes.
This is a freely-available open access publication. Please cite the published version which is available via the DOI link in this record.BACKGROUND: Genome wide association studies have been hugely successful in identifying disease risk variants, yet most variants do not lead to coding changes and how variants influence biological function is usually unknown. METHODS: We correlated gene expression and genetic variation in untouched primary leucocytes (n = 110) from individuals with celiac disease - a common condition with multiple risk variants identified. We compared our observations with an EBV-transformed HapMap B cell line dataset (n = 90), and performed a meta-analysis to increase power to detect non-tissue specific effects. RESULTS: In celiac peripheral blood, 2,315 SNP variants influenced gene expression at 765 different transcripts (< 250 kb from SNP, at FDR = 0.05, cis expression quantitative trait loci, eQTLs). 135 of the detected SNP-probe effects (reflecting 51 unique probes) were also detected in a HapMap B cell line published dataset, all with effects in the same allelic direction. Overall gene expression differences within the two datasets predominantly explain the limited overlap in observed cis-eQTLs. Celiac associated risk variants from two regions, containing genes IL18RAP and CCR3, showed significant cis genotype-expression correlations in the peripheral blood but not in the B cell line datasets. We identified 14 genes where a SNP affected the expression of different probes within the same gene, but in opposite allelic directions. By incorporating genetic variation in co-expression analyses, functional relationships between genes can be more significantly detected. CONCLUSION: In conclusion, the complex nature of genotypic effects in human populations makes the use of a relevant tissue, large datasets, and analysis of different exons essential to enable the identification of the function for many genetic risk variants in common diseases.Coeliac UKNetherlands Organization for Scientific ResearchCeliac Disease Consortium (an innovative cluster approved by the Netherlands Genomics Initiative and partly funded by the Dutch government)Netherlands Genomics InitiativeWellcome Trus
Use of autologous bone graft associated with support osteosynthesis for tibial edge bone losses in total knee prostheses
OBJETIVO: Relatar os resultados iniciais com o uso de nova técnica para a fixação de enxerto ósseo em falhas ósseas tibiais não contidas em pacientes submetidos à prótese total de joelho. MÉTODOS: Seis pacientes com deformidade grave em varo do joelho que, após a realização dos cortes e balanço ligamentar, ainda apresentavam falhas ósseas avançando até à margem do corte tibial e que comprometiam a estabilidade do implante, foram submetidos a uma nova técnica de fixação. RESULTADOS: Cinco dos pacientes apresentaram bom resultado clínico, com integração do enxerto em até 12 semanas. Um paciente apresentou complicação clínica com deiscência da ferida e exposição da prótese, evoluindo para a retirada do implante e artrodese do joelho. CONCLUSÃO: A osteossíntese de suporte como método de fixação do enxerto é uma opção viável para o tratamento das falhas ósseas tibiais. A técnica proposta certamente necessita de mais estudos para a sua validação.OBJECTIVE: To report the initial results from the use of a new technique for fixation of bone grafts in uncontained tibial bone defects in patients undergoing total knee prosthesis implantation. METHODS: Six patients with severe varus deformity of the knee who, after cuts and ligament balancing had been performed, still presented bone deficiencies that reached the edge of the tibial cut and compromised the implant stability, underwent a new fixation technique. RESULTS: Five of the patients had good clinical results, with integration of the graft within 12 weeks. One patient presented clinical complications with wound dehiscence and implant exposure, which evolved to the need for implant removal and knee arthrodesis. CONCLUSION: Support osteosynthesis as a graft fixation method is a viable option for treating tibial bone deficiencies. The proposed technique certainly needs further studies for its validation
Comparison of two methods for in vitro multiplication of Radopholus similis and Pratylenchus brachyurus in carrot cylinders
ABSTRACTThe use of in vitro mass multiplication of nematodes under axenic conditions allows intensification of studies on taxonomy, biology, epidemiology and control of these pathogens. In the present study, two methods were compared for in vitro multiplication of two species of plant-parasitic nematodes, Radopholus similis and Pratylenchus Brachyurus in 20, 40 and 60 day-periods. Both techniques involved the use of carrot cylinders placed in jars with lids, with water–agar in the bottom of the flasks (WA+) or without (WA-). In WA- the nematodes
were treated with a 1% solution of ampicillin whilst for WA+ the axenization was carried out with a solution of mercuric chloride (0.01%), and streptomycin sulfate 0.02%. The WA+ condition was the most favorable for multiplication of both species of nematodes, resulting in a population increase of about 280 times for R. similis and 226 times for P. brachyurus in relation to the founding population of 25 individuals. For WA- a population increase of only five times after 60 days for R. similis and a duplication of the population after 60 days for P. brachyurus was obtained. Overall, the largest amount of nematodes occurred at 60 days after inoculation
Tearing Out the Income Tax by the (Grass)Roots
Landscapes are increasingly fragmented, and conservation programs have started to look at network approaches for maintaining populations at a larger scale. We present an agent-based model of predator–prey dynamics where the agents (i.e. the individuals of either the predator or prey population) are able to move between different patches in a landscaped network. We then analyze population level and coexistence probability given node-centrality measures that characterize specific patches. We show that both predator and prey species benefit from living in globally well-connected patches (i.e. with high closeness centrality). However, the maximum number of prey species is reached, on average, at lower closeness centrality levels than for predator species. Hence, prey species benefit from constraints imposed on species movement in fragmented landscapes since they can reproduce with a lesser risk of predation, and their need for using anti-predatory strategies decreases.authorCount :
