Joint dynamic probabilistic constraints with projected linear decision rules

We consider multistage stochastic linear optimization problems combining joint dynamic probabilistic constraints with hard constraints. We develop a method for projecting decision rules onto hard constraints of wait-and-see type. We establish the relation between the original (in nite dimensional) problem and approximating problems working with projections from di erent subclasses of decision policies. Considering the subclass of linear decision rules and a generalized linear model for the underlying stochastic process with noises that are Gaussian or truncated Gaussian, we show that the value and gradient of the objective and constraint functions of the approximating problems can be computed analytically.

Role of the oblique ligament in the integrity of the medial collateral ligament of the canine elbow joint

Foram estudados o arranjo e o diâmetro médio das fibrilas colágenas do ligamento colateral medial da articulação do cotovelo do cão, isolado ou associado ao ligamento oblíquo e tracionado até a ruptura. Dezoito articulações foram divididas em três grupos. O primeiro grupo teve o ligamento colateral medial coletado, mas não tracionado; o segundo grupo teve o ligamento colateral medial tracionado isoladamente; o terceiro grupo teve os ligamentos colateral medial e oblíquo tracionados associadamente. O ligamento colateral medial não submetido ao ensaio de tração apresentou um padrão ondulado das fibras colágenas, o qual não foi totalmente destruído quando foi tracionado, associado ao ligamento oblíquo, e perdeu totalmente o padrão reticular das fibras colágenas quando testado isoladamente. Quando o ligamento colateral medial foi submetido à tensão isoladamente, o diâmetro médio das fibrilas colágenas aumentou em relação ao grupo não submetido à tensão. Associado ao ligamento oblíquo, o diâmetro médio das fibrilas colágenas foi o maior na região de inserção e o menor na região média, em relação aos outros grupos. Concluiu-se que o ligamento oblíquo pode favorecer a integridade da região de inserção do ligamento colateral medial, aumentando a eficácia de sua reconstrução após a lesão.

Conhecimento do enfermeiro sobre as ações de vigilância epidemiológica no Hospital Universitário Onofre Lopes, Natal, RN

This is an exploratory descriptive study with quantitative approach, aiming to verify the nurses' knowledge concerning the epidemiological surveillance activities at the Onofre Lopes hospital (HUOL), in Natal, Rio Grande do Norte. The study was performed with 63 nurses from the hospital and the data were collected through a questionnaire. All data were analyzed using descriptive statistics. The results were discussed and organized into four sections: nurses' knowledge on hospital epidemiological surveillance; procedures of the professional nurse through compulsory notification diseases; difficulties found by nurses to register the compulsory notification diseases and suggestions of strategies to joint epidemiological surveillance service with the care practices of nurses. The results showed that 55.55% of nurses know the main action of epidemiological surveillance, compulsory notification of diseases, and that 42.86% reported to the Hospital Epidemiology Center , while 57.14% did not allocate the information for this service. Most nurses found it difficult to perform notification for not knowing its flow; for the surveillance service does not operate 24 hours and for vagueness on diagnostic of disorders. Suggestions of strategies to improve the quality of epidemiological information are focused on training of nurses in hospital epidemiological surveillance; working in partnership with the surveillance center; diffusion of information on surveillance and conducting a daily active search. It comes to conclusion that most nurses don't notify the Surveillance Center about Compulsory Notification Diseases and it wasn't observed the incorporation of integrality values between the hospital surveillance and all nurses, since this principle guides the actions of health services based on dialogue, listening, ethical commitment, sharing of knowledge among professionals of various services and respect towards other professionals. Therefore, the integrality gap in the actions of the nurses studied, as well as in the surveillance service does not mobilize the potential of such services to changes in the sense of achievement of practices aimed at a special attention model that combines preventive and corrective actions, proposed and desired by SUS. Through the difficulties presented, it becomes important to recommend educational processes with strategy to transform the conducts, besides proposing actions under the principle of integrality provide responses agile and effective, as the purpose of VE hospital emergency care by the current epidemic

A inserção da equipe da Estratégia Saúde da Família em um Centro Municipal de Educação Infantil na promoção da saúde da criança

The joint enters the teams of the Strategy Health of Family (ESF) and the Municipal Center of Infantile education (CMEI) blunts as a form to assure the monitoring and promotion to the health of the children of 2 the 5 years when entering the day-care center environment/daily pay-school. It was traced as objective: To analyze the actions developed for the team of the Strategy Health of the Family in the promotion the health of the child, taken care of in a CMEI. Description-exploratory is to a study, qualitative nature, the type research-action. Developed in a CMEI and the USF of the quarter of New City, Natal-RN. The population was constituted by the professionals of the team of the ESF and the CMEI and parents. During the stages of the research-action diverse techniques had been used as the individually interview and in group, focal group, comment participant, and daily of field. The analysis of the data occurred by means of the content analysis, in the thematic modality, proposal for Bardin (1977) and description of the stages of the research-action. In the stage of situational diagnosis that it investigates the reality lived deeply for the citizens of ESF and CMEI how much to the health of the child seven categories had emerged that they enclosed: the context of the attention child in the CMEI identifying the actions that already came being developed for the ESF in the CMEI; the functioning of the CMEI and its routine of activities; the paper of the CMEI in the care the child; the daily one of the ESF, how much to the care to the health of the child of 2 the 5 years involving the diverse difficulties faced for the ESF; difficulties faced in daily of the CMEI for the care the child of 2 the 5 years; paper of joint ESF and CMEI for the confrontation of the difficulties; e action of health to be developed that they had subsidized the stage of planning of the research-action. During the stages of planning and implementation of the actions the actions of education in health with professionals of the CMEI and parents had been materialize and the actions of direct attention the health of the child. In the stage of evaluation of the actions for the involved citizens one searched to ahead understand the perception of the actions developed and perspective of continuity of the actions, through 4 boarded subjects for the citizens. For all the passage of the research-action it can be inferred that joint ESF and CMEI is a necessary initiative ahead of the current situation of the services of health for the promotion of an integral attention the health of the child, but that the teams of the ESF not yet make use of material conditions and staff enough to develop actions that exceed the limits of the USF, being necessary for this the reinforcement of the joints mainly with the Federal University of the Rio Grande of the North.

Study on the bone mineral density of broiler suffering femoral joint degenerative lesions

An experiment was carried out with male and females broilers of two different commercial breeds to evaluate bone mineral density of the right femur head. A number of 600 one-day-old broilers were raised in an experimental poultry house up to 42 days of age at the School of Veterinary Medicine and Animal Science of UNESP, Botucatu, Brazil. After slaughter, three males and three females in each breed in each of the established gross scores were selected. Their femora heads were submitted to gross examination, and subsequently the thighs were submitted to the Veterinary Hospital for radiographic analysis. Femora were also submitted to bone resistance, Seedor index, and dry matter content analyses. All these bone quality characteristics were different between males and females, independent of breed. Breeds presented similar behavior. It was possible to establish correlations between bone quality parameters, and confidence intervals for bone mineral density values, correlating them to femoral degeneration score, which allows characterizing femoral head lesions by radiographic optical densitometry.

O ambulatório de Saúde Mental no contexto da Reforma Psiquiátrica em Natal/RN

The years 1990 disclose the consolidation of the Brazilian Psychiatric Reform project, assumed as official politics by the Health Department, also stirring up discussions, lines of direction and new ways of care. Substitutive services to the psychiatric hospital as CAPS, conviviality centers, therapeutical residences and ambulatory clinics are implemented. This work analyzes the relations that the Specialized Ambulatory Clinic of Ribeira establishes to the services of Mental Health of the public system in the city of Natal/RN, as well as its adjustment to the proposal of the Psychiatric Reform. Through semi-structured interviews and observation, it was possible to gather data which allowed picturing a general characterization of the service: activities, technical group, joint with other institutions, daily routine organization. Such institution develops activities that surpass the traditional character of a clinic- in other words, the psychological/medical appointments - and it mainly greets the ones proceeding from CAPS and psychiatric hospitals. It offers group activities, psychiatric appointments, therapeutical workshops, sheltering and strolls, among others. The institution is composed by a multi-professional team of psychiatrists, psychologists, occupational therapists, nurse s aide and art-educator. The joint of this service with others that make part of the Mental Health Assistance network in Natal is incipient. Due to this fact, some actions and activities that could and should be developed together are just not. Although facing difficulties, the professionals of the Ambulatory Clinic of Ribeira are able to achieve good results and establish care in Mental Health that prioritize sheltering, listening and respect to the user s individuality. The Ambulatory Clinic of Ribeira is organized according to the paradigm of the Psychiatric Reform. Therefore, it offers an attention that stimulates the re-socialization of the users and the exercise of the citizenship and autonomy of those

Modeling and Experimental Aspects of Self-healing Bolted Joint through Shape Memory Alloy Actuators

Bolted joints are a form of mechanical coupling largely used in machinery due to their reliability and low cost. Failure of bolted joints can lead to catastrophic events, such as leaking, train derailments, aircraft crashes, etc. Most of these failures occur due to the reduction of the pre-load, induced by mechanical vibration or human errors in the assembly or maintenance process. This article investigates the application of shape memory alloy (SMA) washers as an actuator to increase the pre-load on loosened bolted joints. The application of SMA washer follows a structural health monitoring procedure to identify a damage (reduction in pre-load) occurrence. In this article, a thermo-mechanical model is presented to predict the final pre-load achieved using this kind of actuator, based on the heat input and SMA washer dimension. This model extends and improves on the previous model of Ghorashi and Inman [2004, "Shape Memory Alloy in Tension and Compression and its Application as Clamping Force Actuator in a Bolted Joint: Part 2 - Modeling," J. Intell. Mater. Syst. Struct., 15:589-600], by eliminating the pre-load term related to nut turning making the system more practical. This complete model is a powerful but complex tool to be used by designers. A novel modeling approach for self-healing bolted joints based on curve fitting of experimental data is presented. The article concludes with an experimental application that leads to a change in joint assembly to increase the system reliability, by removing the ceramic washer component. Further research topics are also suggested.

Práticas educativas e integralidade na saúde da família: um estudo etnográfico

Primary Health Care, especially in the family health strategy, it is expected that the joint assistance and actions of health promotion. The Ministry of health (BRAZIL, 2007) defines health education as an eyeshadow strategy of prevention and health promotion, based on reflective practices, which allow the user to their condition of historical, social and political subject, under the vision of an expanded clinic on the part of health professionals. In this sense, there are guidelines for it professionals to develop educational activities and that they can interfere in the health/disease process of the population, with a view to the development of autonomy of the subject. This research had as objective to understand in the light of the integrality of the care, as is the production of health education practices, within the framework of the family health strategy from ethnographic study in a family health unit (USF). The location of the research was the unit of USF Felipe Camarão II in West Health District, in the city of Natal, RN, Brazil, selected from preliminary mapping of educational practices deployed in units of health of the family of this municipality, based on criteria such as time-to-deployment of USF and sustainability of existing actions. Immersion in the field consisted of participant observation with journaling, held during the period of August 2012 to January 2013, in which she accompanied team work processes in clinical-welfare actions on the USF, in households and in educational activities of group character. The results presented in ethnographic description were analyzed based on the axes proposed by Ayres (2009) for identification of integrality in health practices:the axis of the needs; the axis of the purposes; the joint axis; and the axis of the interactionsThe evidence described from observation point the presence of each axle up health education practices developed by the teams, even incipient form, namely: articulation and appreciation of knowledge and practices of popular culture with local initiatives (Pastoril do Peixe Boi Encantado, Auto de Natal e Grupo Terapia e Arte); Clinical integration with health promotion actions and coordination of multidisciplinary knowledge, with professional-user link (course for pregnant women). However, a few challenges were identified to be faced in order to move forward in these practices in integral care: the need to break with the fragmentation of actions; strengthening teamwork; need for greater sustainability policy of collective actions; intersectoral work aimed at a better role of the State in the face of the health-disease process, adding to the action of individuals.The analysis produced from observation of the processes experienced indicates the need for a better recognition of local managers that actions similar to those that occur in the USF Felipe Camarão II enable advances in completeness as allows inclusion of actors involved in the processes of health work, and stimulate participation and shared responsibility in the fight for health-disease situations

A imanência como lugar do ensino de filosofia

A intenção do presente artigo é pensar a problemática do ensino de filosofia a partir da obra de Deleuze e Guattari. Esses autores criaram uma série de conceitos, em seu fazer filosófico, para entender o que seria fazer filosofia, ou seja, para entender a atividade filosófica que se distanciasse de uma reflexão sobre alguma coisa e se fundasse em um ato de criação filosófica. Segundo os autores, existem quatro conceitos que corroboram para entender esse fazer filosófico, quais sejam: conceito, plano de imanência, personagem conceitual e problema. Tem-se como hipótese que tais conceitos podem contribuir para se pensar o ensino de filosofia na contemporaneidade de modo diferenciado do qual vem sendo tratado. Foi dada especial atenção a um desses conceitos: plano de imanência, engendrado na última obra conjunta desses autores, O que é a filosofia? (1997). Buscou-se, na obra desses autores, a caracterização de imanência e, consecutivamente, de plano de imanência para entender como se pode pensar o ensino de filosofia de forma diferenciada e de modo tal a distanciá-lo de uma adequação conceitual a um transcendente ou a um transcendental, a qual, no entender dos autores trabalhados, levaria o conceito de ensino a um dogmatismo conceitual. A proposta deste artigo é buscar uma saída para o problema, pensando o ensino de filosofia a partir da imanência mesma na qual este se produz.

Radiographic Abnormalities in Barrel Racing Horses with Lameness Referable to the Metacarpophalangeal Joint

Barrel racing is one of the most popular uses of the American Quarter horse in North and South America. Although injury to the metacarpophalangeal joint frequently occurs in this sport, there is limited information describing the nature of these injuries. The aim of this study was to determine the most common radiographic abnormalities in barrel racing horses with lameness referable to the metacarpophalangeal joint. lameness examinations were performed on 63 barrel racing horses. Those found to be lame were subjected to radiographic examination. Lameness at trot was scored on a scale of 0-5 (0 = sound; 5 = inability to move). Data were analyzed using descriptive statistical analysis. of horses examined, 30 (47.6%) were lame with scores ranging from 1 to 4. Half of the lame horses (15 of 30) had grade 2 lameness of the right forelimb. Abnormal radiographic findings were more often present on the left forelimb and included signs of sesamoiditis (70%), villonodular synovitis (56.6%), osteoarthritis (36.6%), osteochondritis dissecans (13.3%), capsulitis (13.3%), and soft-tissue swelling (6.6%). Radiographic abnormalities indicated that sesamoiditis, villonodular synovitis, and osteoarthritis may be associated to mild-to-moderate lameness in barrel racing horses. Complementary sonographic evaluation is recommended to better characterize soft-tissue abnormalities. (C) 2012 Elsevier B.V. All rights reserved.

Origin of sensory and autonomic innervation of the rat temporomandibular joint: A retrograde axonal tracing study with the fluorescent dye fast blue

Previous studies that have used retrograde axonal tracers (horseradish peroxidase alone or conjugated with wheat germ agglutinin) have shown that the temporomandibular joint (TMJ) is supplied with nerve fibers originating mainly from the trigeminal ganglion, in addition to other sensory and sympathetic ganglia. The existence of nerve fibers in the TMJ originating from the trigeminal mesencephalic nucleus is unclear, and the possible innervation by parasympathetic nerve fibers has not been determined. In the present work, the retrograde axonal tracer, fast blue, was used to elucidate these questions and re-evaluated the literature data. The tracer was deposited in the supradiscal articular space of the rat TMJ, and an extensive morphometric analysis was performed of the labeled perikaryal profiles located in sensory and autonomic ganglia. This methodology permitted us to observe labeled small perikaryal profiles in the trigeminal ganglion, clustered mainly in the posterior-lateral region of the dorsal, medial and ventral thirds of horizontal sections, with some located in the anterior-lateral region of the ventral third. Sensory perikarya were also labeled in the dorsal root ganglia from C2 to C5. No labeled perikaryal profiles were found in the trigeminal mesencephalic nucleus. on the other hand, autonomic labeled perikaryal profiles were distributed in the sympathetic superior cervical and stellate ganglia, and parasympathetic otic ganglion. Our results confirmed those of previous studies and also demonstrated that: (i) there is a distribution pattern of labeled perikaryal profiles in the trigeminal ganglion; (ii) some perikaryal profiles located in the otic ganglion were labeled; and (iii) the trigeminal mesencephalic nucleus did not show any retrogradely labeled perikaryal profiles.
