Mahoney is shown closing the Armature Switch of a Rotary Converter in a D.C. substation. The average rotary in our stations has a capacity of 4,200 K.W. and there are 30 such stations in Manhattan with an annual output of 800,000 amperes. Although the D.C. load is gradually being reduced, it can be seen that there is still considerable demand for direct current in Manhattan." Black and white photograph.

Short-wave instabilities in the Benjamin-Bona-Mahoney-Peregrine equation: theory and numerics

In this paper we discuss the nonlinear propagation of waves of short wavelength in dispersive systems. We propose a family of equations that is likely to describe the asymptotic behaviour of a large class of systems. We then restrict our attention to the analysis of the simplest nonlinear short-wave dynamics given by U-0 xi tau, = U-0 - 3(U-0)(2). We integrate numerically this equation for periodic and non-periodic boundary conditions, and we find that short waves may exist only if the amplitude of the initial profile is not too large.

Cluster and cluster galaxy evolution history from IR to X-ray observations of the young cluster RX J1257.2+4738 at z=0.866

Context. The cosmic time around the z similar to 1 redshift range appears crucial in the cluster and galaxy evolution, since it is probably the epoch of the first mature galaxy clusters. Our knowledge of the properties of the galaxy populations in these clusters is limited because only a handful of z similar to 1 clusters are presently known. Aims. In this framework, we report the discovery of a z similar to 0.87 cluster and study its properties at various wavelengths. Methods. We gathered X-ray and optical data (imaging and spectroscopy), and near and far infrared data (imaging) in order to confirm the cluster nature of our candidate, to determine its dynamical state, and to give insight on its galaxy population evolution. Results. Our candidate structure appears to be a massive z similar to 0.87 dynamically young cluster with an atypically high X-ray temperature as compared to its X-ray luminosity. It exhibits a significant percentage (similar to 90%) of galaxies that are also detected in the 24 mu m band. Conclusions. The cluster RXJ1257.2+4738 appears to be still in the process of collapsing. Its relatively high temperature is probably the consequence of significant energy input into the intracluster medium besides the regular gravitational infall contribution. A significant part of its galaxies are red objects that are probably dusty with on-going star formation.

Manipulation of colonic bacteria and volatile fatty acid production by dietary high amylose maize (amylomaize) starch granules

Aims : To study the effects of amylomaize starch and modified (carboxymethylated and acetylated) amylomaize starches on the composition of colonic bacteria and the production of volatile fatty acids, in mice. Methods and Results : Balb/c mice were fed with experimental diets containing various amount of amylomaize and modified amylomaize starches. Colonic bacterial populations and short-chain fatty acids were monitored. Results showed that the increases in indigenous bifidobacteria were detected in mice fed all starches tested; however, the highest numbers were observed in the group fed with 40% unmodified amylomaize starch. The starch type influenced the populations of indigenous Lactobacillus , Bacteroides and coliforms. High Lactobacillus numbers were achieved in the colon of mice fed with high concentration of amylomaize starch. Acetylated amylomaize starch significantly reduced the population of coliforms. In addition, orally dosed amylomaize utilizing bifidobacteria reached their highest levels when fed together with amylomaize or carboxymethylated amylomaize starch and in both cases butyrate levels were markedly increased. Conclusions: These results indicate that different amylomaize starches could generate desirable variation in gut microflora and that particular starches may be used to selectively modify gut function. Significance and Impact of Study: Amylomaize starch appeared to enhance the desirable composition of colonic bacteria in mice, and suggested it possessed the potential prebiotic properties.MTherefore, resistant starch and its chemical derivatives may exert beneficial impacts to the human colon.

A Família no Hospital. A Percepção da Prática do Enfermeiro na Preparação para a Alta Hospitalar

O presente artigo descreve um estudo realizado com o objectivo de identificar as dificuldades e necessidades de formação e informação por parte de cuidadores informais na prestação de cuidados, no domicílio, à pessoa idosa com dependência funcional na mobilidade. Pretendeu-se também conhecer a percepção destes cuidadores acerca da (in)formação proporcionada pelo enfermeiro durante o internamento da pessoa idosa, assim como medidas sugeridas para melhorar a preparação da alta hospitalar. Este trabalho foi elaborado no âmbito da Monografia do Seminário de Reflexão Final de Curso, 4º ano do 6º Curso de Licenciatura em Enfermagem, na Escola Superior de Enfermagem de Lisboa Pólo Calouste Gulbenkian - Julho de 2008. Foi utilizada uma metodologia qualitativa com aplicação prévia do Índice de Barthel (Mahoney e Barthel, 1965) para a classificação da capacidade funcional ao nível das Actividades Básicas de Vida Diária (ABVD)de pessoas idosas internadas no serviço de Medicina de um Hospital Central. Este procedimento possibilitou a selecção indirecta dos quatro cuidadores, sujeitos empíricos, aos quais foram realizadas entrevistas semidirectivas. Da análise dos discursos produzidos, verifica-se que o cuidador informal evidencia algumas dificuldades na prestação de cuidados à pessoa idosa com dependência funcional, o que se traduz em necessidades de ensino no apoio às ABVD sobretudo ao nível da Alimentação, Posicionamento, Transferência e Higiene corporal. O cuidador refere ter uma melhor preparação para a alta no que concerne à execução de procedimentos técnicos aliado ao estabelecimento de uma relação de parceria com o enfermeiro. A experiência prévia como cuidador revelou-se como uma mais-valia na gestão dos cuidados e mobilização de recursos, embora não aparente ser suficiente perante o agravamento e novas situações.

Investigações sôbre inibidores para o vírus da poliomielite, presentes em soros de bovinos

Inibidores contra as amostras de poliovírus do tipo 1, Mahoney e CHAT, foram estudados no sistema de gel de hidróxido de alumínio. O inibidor comportou-se como uma macroglobulina do tipo 19 S (IgM), através filtração em gel (Sephadex G-200), partição em DEAE-Celulose e sedimentação por ultra-centrifugação em gradiente de sacarose. O inibidor foi ainda destruído através o tratamento com 2-Mercapto-Etanol. O inibidor une-se à superfície do vírus na ausência de células. O complexo formado pelo vírus e o inibidor pode ser precipitado por um sôro preparado contra a globulina bovina; o mesmo complexo dissocia-se em idêntico valor de pH ao do complexo vírus-anticorpo 19 S. A chamada infecciosidade residual (cêrca de 10%) que permanece após a neutralização de poliovírus com sôro bovino representa uma dissociação parcial do inibidor da partícula de vírus, quando em presença das células em cultura. Foram obtidas amostras de vírus resistentes à ação específica de soros bovinos. Estas amostras permanecem sensíveis à ação de outros soros bovinos ativos, bem como à ação de anticorpos 7 S e 19 S. Através experiências de adsorção de atividade inibidora, foi possível mostrar a existência de inibidores monoespecíficos, com diferentes especificidades contra as amostras CHAT e Mahoney, respectivamente.
