Efetividade do exercício físico em ambiente ocupacional para controle da dor cervical, lombar e do ombro: uma revisão sistemática

Abstract: Background: Musculoskeletal disorders have been recognized as a worldwide health problem One of the measures for controlling these disorders is workplace exercise, either at the workstation or in a separate environment within the company However, there is controversy regarding the effectiveness and means of applying these interventions Objectives: To assess and provide evidence of the effectiveness of workplace exercise in controlling musculoskeletal pain Methods: The following databases were searched: PubMed, MEDLINE, Embase, Cochrane, PEDro and Web of Science Two independent reviewers selected the elegible studies Possible disagreements were solved by consensus All randomized controlled clinical trials that evaluated exercise interventions in the workplace musculoskeletal pain relief were included The PEDro scale (range=0-10 points) was used to rate the quality of the studies included in this review Results and Conclusions: The electronic search yielded a total of 8680 references published in English At the end of the selection process, 18 studies were included Strong evidence was found to support the effectiveness of physical exercise in controlling neck pain among workers who performed sedentary tasks in offices or administrative environments, while moderate evidence was found for low back pain relief among healthcare and industrial workers who performed heavy physical tasks These positive results were reported when the training periods were longer than 10 weeks, the exercises were performed against some type of resistance and the sessions were supervised None of the studies evaluating sedentary workers reported positive results for controlling musculoskeletal shoulder pain Further randomized controlled trials are needed to comparatively evaluate, among other aspects, the effects of light and heavy training for shoulder pain relief

Vanadium Pentoxide Nanostructures: An Effective Control of Morphology and Crystal Structure in Hydrothermal Conditions

Abstract: A systematic study was made of the synthesis of V2O5·nH2O nanostructures, whose morphologies, crystal structure, and amount of water molecules between the layered structures were regulated by stric...

A fast and reliable protocol for wireless sensor networks in critical conditions monitoring applications

Abstract: Sensor networks are increasingly being deployed for fine-grain monitoring of physical environments subjected to critical conditions such as fire, leaking of toxic gases and explosions A great challenge to these networks is to provide a fast, reliable and fault tolerant channel for events diffusion, which meets the requirements of query-based, event-driven and periodic sensor networks application scenarios, even in the presence of emergency conditions that can lead to node failures and path disruption to the sink that receives those events This paper presents a fault tolerant and low latency algorithm, which we refer to as PEQ (Periodic, Event-Driven and Query-Based Protocol), that meets sensor networks requirements for critical conditions surveillance applications The algorithm uses the publish/subscribe paradigm to disseminate requests across the network and an ack-based scheme to provide fault tolerance The algorithm was implemented using NS-2 simulator and compared to the Directed Diffusion paradigm Important metrics were evaluated showing that the proposed algorithm can be a proper solution to meet constraints and requirements of events delivery in critical conditions monitoring applications
