Alguns autores usaram medições da \emph{Phasor Measurement Unit} (PMU) para calcular índices e monitorar o quão perto o sistema está do Ponto de Máximo Carregamento (PMC). No entanto, para poder aplicar corretamente esses índices, deve funcionar para todos os tipos de aumento de carga. Este artigo investiga o desempenho de alguns índices existentes para avaliar a margem de estabilidade. Apenas PMC devido a Bifurcação do tipo Sela-Nó (BSN) foi considerado neste artigo. Os resultados indicam que esses índices são fortemente dependentes da direção do aumento da carga e não conseguem detectar corretamente o ínicio de um colapso de tensão.

Objective: To identify the presence of perioperative complications and their relationship with preoperative factors and intraoperative anesthetic behavior that may constitute indicators of prediction of complications. Materials and Methods: An analytical, observational, longitudinal, retrospective study was carried out in 476 obese patients surgically operated by laparoscopic vertical gastroplication. Immediate intraoperative and postoperative clinical complications and their relationship with demographic, clinical, anthropometric and anestheticdependent variables were identified, which constituted risk factors. With the risk factors identified, a prognostic index was constructed and subsequently validated. Results: The immediate intraoperative and postoperative complications were few. It was possible to identify three independent risk factors, given by the previous respiratory functional status, the anesthetic technique used and the surgical time. A prognostic index of complications was constructed that grouped patients at low, intermediate and high risk of presenting complications. Conclusions: The grouping of risk factors as a predictive index of complications was effective because the complication prediction capacity could be estimated and validated.

Developed a general description of the company, its activities, processes and operations; through population survey assessed the level of impact in the area of influence and by the technique of Leopold, identified caused impacts, for finally using the logical framework approach propose the EMP. The base line of the diagnosis establishes that the magnitude of impacts lies in the emission of gases due to poor technology, inadequate infrastructure, untrained staff and scarce implementation of environmental standards. As such, the Plan Environmental Management (WFP) has been developed for processing plant of feather meal as a methodological tool of management which establishes strategies, programmes and actions aimed to mitigate, reduce or prevent these impacts the development of the company and of the local level in a sustainable manner.

Classical method for hybrids obtainement is to develop pure lines through inbreeding and continuous selection for several generations, until lines with sufficient homozygous presenting desirable traits. Therefore, the objective of this study was to determine the heterosis level for yield of experimental maize hybrids in La Comarca Lagunera, Mexico. The work was developed the Autonomus Agrarian University "Antonio Narro", Laguna Campus (UAAAN-UL). In 2010, six CIMMYT's lines were selected. The history of evaluations carried out by INIFAP through 2010-2011 period for that region. In march, 2011, were done the possible crosses between the parents according with Griffing's method 2 (1956) obtaining 15 crosses. Parental lines (P) showed a per-sé performance ranged from 6279 kg ha-1 to 8728 kg ha-1. These yields were higher considering that are inbred lines, but with a wide range of adaptation, including for the Comarca Lagunera. Heterosis level ranged from 44% to 81%, for the first five high yield hybrids. Finally, a parental four line was present in four of the five best hybrids, indicating that is feasible to use this in future crosses to get commercial hybrids.

Its usage has increased in the last decade as the understanding of its functions, advantages and disadvantages increases. Unfortunately, it continues to be associated with very high morbidity and mortality, and the different techniques used to protect the intra-abdominal contents cannot be standardized for all surgical circumstances. The objective is to review the origins, actual indications and controversies of the staged abdominal repair (STAR) and to report on the latest and most used techniques to ensure an optimal temporary abdominal closure (TAC). A search was done in Medline and Ovid for articles with key words of open abdomen, temporary abdominal closure and staged abdominal repair. We found the use of the technique is justified in patients with trauma, abdominal compartment syndrome and patients with severe intra-abdominal sepsis. The technique used for TAC must always be individ...

Few reports have been published in the literature describing congenital lumbar hernia. We present the case of a patient with congenital lumbar hernia and a review describing the regional anatomy, laparoscopic techniques as a surgical alternative, and the impact of modern imagenology in diagnosis, confirmation and demarcation of the aponeurotic defect, in order to update information and to provide the surgeon with the tools for optimal perioperative preparation and the best operative technique for this rare disease. We describe here the case of a 5-month-old Mexican female infant with a right lumbar bulging. Ultrasonographic findings showed an aponeurotic defect and an ipsilateral renal agenesia. Open surgical repair was carried out with identification of the defect in the superior or Grynfellt-Lesshaft's triangle and t...

É também relatado o emprego dos raios laser em medicina, desde os estudos experimentais de fotocoagulação em retina de animais, até sua utilização em placas de ateroma e no músculo cardíaco, dando destaque para os trabalhos pioneiros realizados no Brasil. São também descritos os métodos indiretos de revascularização miocárdica, que serviram de base para o emprego dos raios laser na cirurgia de revascularização transmiocárdica, além dos protocolos randomizados que demonstraram ser esse procedimento adequado para o tratamento de um grupo seleto de pacientes. É dado enfoque especial para o tipo de doente selecionado para a revascularização com raios laser, constituído por pacientes na fase final da doença arterial coronária, com miocárdio isquêmico (porém, viável) e que ainda apresentam angina, apesar de esgotados todos os recursos habituais de tratamento, especialmente a revascularização miocárdica clássica e a angioplastia. A experiência do Instituto do Coração, num período de dois anos, consiste em 40 pacientes com as características clínicas acima descritas e que foram submetidos à revascularização transmiocárdica com raios laser. Ao final de 12 meses de seguimento, cerca de 87,8% deles obtiveram melhora significativa dos sintomas, com regressão da angina de classes III ou IV, para classes 0, I ou II (p< 0,0001). Foram observados 3 (7,5%) óbitos precoces e 2 tardios ao procedimento. A despeito de discreta melhora na função ventricular esquerda, observada pela ressonância magnética e pelo estudo ecocardiográfico, não houve variação no grau de perfusão miocárdica. O destino dos canais criados pelos raios laser no miocárdio é analisado, com base nos nossos próprios resultados e na experiência relatada na literatura. Discute-se ainda os prováveis mecanismos de ação do método, com enfoque para a denervação miocárdica e a neoangiogênese. A perspectiva futura delineia-se para o seu emprego por procedimentos minimamente invasivos e associados à revascularização clássica do miocárdio. DESCRITORES: Revascularização miocárdica, métodos. Cirurgia a laser, métodos. Dióxido de carbono, uso terapêutico. Angina pectoris.

Method: Between July 1995 and July 1997, 137 consecutive patients with triple vessel coronary atherosclerotic disease underwent complete coronary artery bypass grafting exclusively using arterial grafts. Of these patients, 112 (81.7%) were male, with ages ranging from 36 to 78 years old (mean 56.5 years). Three hundred and sixty-three arterial grafts were used to perform 442 coronary anastomoses, an average of 3.2 coronary anastomoses per patient. The arterial grafts used were left internal thoracic artery (99.3%), right internal thoracic artery (56.2%), radial artery (94.9%), right gastroepiploic artery (13.9%) and inferior epigastric artery (0.7%). In 80 (58.4%) patients, arterial composite "Y" grafts were constructed with the left internal thoracic artery and another arterial graft. Results: No operative deaths occurred. Four (2.9%) deaths occurred in the postoperative period and only one (0.7%) patient needed reoperation in the immediate follow-up. The 7-year actuarial survival was 94.0% and the event free probability (myocardial infarction, angioplasty, reoperation or death) was 87.0%. Conclusions: Good early and midterm clinical follow-ups can be achieved by exclusively using arterial grafts in the complete coronary artery bypass grafting of patients with triple vessel coronary arteriosclerotic disease. A long-term follow-up will be necessary to show the influence of exclusive use of arterial grafts in the surgical treatment of coronary insufficiency. Descriptors: Miyocardial revascularization. Mammary arteries. Arteriosclerosis. Objetivo: Avaliar os benefícios a médio prazo do uso exclusivo de enxertos arteriais em pacientes com doença aterosclerótica coronária triarterial submetidos à revascularização completa do miocárdio.
