O delírio é uma forma de disfunção cerebral aguda que se manifesta como atenção flutuante e função cognitiva prejudicada. Pode apresentar variedade sintomas, incluindo agitação psicomotora significativa, nível consciência deprimido ou ambos. Diversos fatores risco podem desencadear o delírio, os quais são agrupados em duas categorias: riscos predispor paciente ao (modificáveis não modificáveis) relacionados tratamento recebido enquanto na UTI no ambiente. As intervenções aplicadas poderão...
O câncer de próstata, logo depois do cutâneo, é o tipo neoplasia mais frequente diagnosticado em homens todo mundo. A ocorrência próstata está associada à idade e histórico familiar da doença, entre os quais estatisticamente negros têm maior prevalência incidência morte comparação com origem branca. Apesar as taxas mortalidade variarem consideravelmente consoante a população. Não obstante avanços progressos nas terapêuticas, permanece sendo uma diversidade expressiva para acometidos....
As cirurgias cardíacas são comumente associadas a complicações neurológicas, sendo o tipo, complexidade da cirurgia, comorbidades dos pacientes determinantes para acometimentos neurocognitivos, principalmente do delirium. O delírio é uma das pós-operatórias mais comuns em adultos e idosos hospitalizados, causa comum de morbidade mortalidade, muitas vezes sobreposto à demência. Trata-se revisão literatura conduzida conforme as diretrizes PRISMA. Das buscas realizadas nas bases dados foram...
A imunização é uma ação essencial dos serviços de saúde para erradicar, eliminar e controlar doenças imunopreveníveis. Este estudo apresenta evidências sobre a cobertura vacinal em crianças menores cinco anos no Brasil, identificando fatores que influenciam não adesão ao calendário estratégias melhorar essa cobertura. Trata-se pesquisa exploratória, descritiva qualitativa, realizada por meio revisão integrativa da literatura. Foram consultadas as bases dados LILACS, Medline SciELO, com...
Este artigo aborda a inclusão escolar de crianças com Transtorno do Espectro Autista (TEA), destacando desafios e estratégias para uma educação acessível equitativa. O objetivo é analisar as principais dificuldades enfrentadas no contexto escolar, como falta capacitação docente, carência recursos adaptados resistência à implementação metodologias inclusivas. A pesquisa, caráter bibliográfico, fundamenta-se em estudos sobre especial, legislação vigente práticas pedagógicas eficazes. Os...
Introduction: This article presents a systematic review investigating the effectiveness of pelvic floor exercises and biofeedback in rehabilitation men with urinary incontinence. Urinary incontinence can affect up to 60% men, especially after prostate surgery this significantly impacts quality life population. Objective: study aims evaluate treatments involving and/or provide recommendations for clinical practices. Methods: The methodology involves analysis relevant studies english...
Spacecraft maneuvers is a very important topic in aerospace engineering activities today. In more generic way, spacecraft maneuver has the objective of transferring from one orbit to another, taking into account some restrictions. present paper, problem rendezvous considered. this type problem, it necessary transfer but with extra constraint meeting another when reaching final orbit. particular, paper aims analyze between two coplanar circular orbits, seeking perform lowest possible fuel...
The use of innovative technologies in space missions has evolved considerably the last decade. large cables structures to connect spacecrafts and satellites with goal minimize cost created a new field be explored. A brief explanation will considered about papers related equilibrium stability movement systems connected by cables, known as Tether Systems. It presented mathematical formulation for system formed two point masses tether central force field, Keplerian movement. Lagrangian was used...
The solar electric propulsion could be the best option for transports of future due to its high specific impulse when compared chemical propulsion. Electric propellants are being extensively used assist terrestrial satellites maneuvers orbit correction and as primary in missions toward other bodies system. In this work optimization interplanetary using (SEP) Gravity Assisted Maneuver reduce costs mission, is considered. makes a 1 year after departure convenient. Missions several Near Earth...
The goal of the present paper is to study orbital coplanar maneuvers between circular orbits. control available perform this maneuver application several impulses. solutions has searched that minimize total variation velocity be used implement impulses calculated by algorithms. transfer time obtained, but it isn’t considered as an optimization parameter. A genetic algorithm solve problem, combined with Lambert´s Problem associated those transfers. With making comparisons, a numerical...
The Multiple Encounters Problem is described in the literature as problem of finding trajectories for a spacecraft that leaves from mother planet, describes trajectory interplanetary space, and then goes back to planet. present paper extends departure arrival angles are generalized be nonsymmetrical. solutions shown terms true (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:mi>ν</mml:mi></mml:mrow></mml:math>) eccentric anomaly...
A dumbbell-like system is analyzed, considering two mass points connected with a massless and rigid tether length variations, the center of described by Keplerian orbits. This kind system, in certain type configuration, simple conceptualization space elevator. The motion obtained Lagrangian Formulation Central Gravitational Field, perturbations are neglected. Laws control considered for angle systems rotation around mass. Those include uniform rotations or no at all. Stability conditions...
The tethered spacecraft system was studied. This is a three-body problem formed by the main body with larger mass, m1 and m2 are smaller bodies they connected cable. orbited center of mass m2. cable assumed rigid massless. study goal analyze existing equilibrium to tether in two situations: using control law for size constant size. Assuming law, solutions were fixed values independent eccentricity (e) true anomaly (v) system. For case there periodic solutions, continuous discontinuous...
