Documentos inteligentes

Ao longo deste trabalho será apresentada uma solução para sistemas de informação empresarial no domínio da Qualidade. Desenvolvida num ambiente real com recurso a plataforma .NET, a sua eficácia foi posta à prova em várias implementações. Várias organizações necessitam de implementar processos baseados num documento único, que deve conter o registo de toda a informação, mas que exige a intervenção de diferentes colaboradores. Esta necessidade varia muito entre organizações. Para dar resposta a este problema foi desenvolvido um sistema, denominado de Documentos Inteligentes, que, através de várias ferramentas, permite configurar processos, sem recorrer a codificação, baseados no registo de informação, workflow, controlo de acessos e alertas. É justamente a descrição dos vários componentes tecnológicos utilizados para dar resposta aos problemas, que se irá efectuar neste trabalho. Em termos de desenvolvimento de software foram abordados conceitos práticos de engenharia de domínio, RAD, arquitecturas por camadas, abstracção e workflow que possibilitaram uma maior flexibilidade do sistema desenvolvido e que conduz, simultaneamente, a uma rápida implementação de soluções de software baseadas nesta área.

Anti-vibration gloves and the forearm efforts during tools operations

The objective of this paper is to analyze the forearm muscular contraction levels associated to the use of anti-vibration gloves, by comparing the contraction levels with gloves and without gloves. Two different vibration tools were used in a simulated work environment: (1) A compact Duty Multi-Cutter Bosch and (2) and a Percussion Drill with a drill bit Ø20 mm. Standard operations were performed by each subject in the following materials: (1) Performing cross- sectional cuts in 80x40 mm pine section and (2) performing 20 mm diameter holes in a concrete slab 2 x 2 m, 70 mm thick. The forearm contraction level were measured by surface electromyography in four different muscles: Flexor Digitorum Superficialis (FDS), Flexor Carpi Ulnaris (FCU), Extensor Carpi Radialis Longus (ECRL) e Extensor Carpi Ulnaris (ECU). For the flexor muscles (FDS, FCU), an increase tendency in muscular contraction was observed when the operations are performed without gloves (2-5% MVE increase in the FDS and 3-9% MVE increase in the FCU). For the extensor muscles ECU a decrease tendency in muscular contraction was observed when the operations are performed without gloves (1-10% MVE decrease). Any tendency was found in the ECRL muscle. ECU was the muscle with the highest contraction level for 79% and 71% of the operators, during the operations respectively with the multi-cutter (P50= 27-30%MVE) and with the percussion drill (P50=46-55%MVE). As a final conclusion from this study, anti- vibration gloves may increase the forearm fatigue in the posterior region of the forearm (ECU muscle) during operations with the mentioned tools

Changes in pentobarbital induced sleeping-time in mice infected with Schistosoma mansoni and immunosuppressed

To evaluate whether the intensity of the hepatic granulomatous response induced by S. mansoni eggs plays a role in drug metabolism, mice were infected with 40 cercariae and tested to assess the sodic pentobarbital induced sleeping-time. To decrease the inflammatory reaction the animals were irradiated with 400 Rad or received azathioprine, 20mg/kg, 3 times a week, for 4 weeks, respectively in or beginning in the 33th post-infection day. In infected animals receiving azathioprine the area of the hepatic granulomas was smaller and the sleeping-time was similar to that of non-infected ones (controls). In mice infected and irradiated the granuloma dimensions were similar to those of animals only infected, in these two latter groups of animals, the sleeping-time was more prolonged than that of the control animals. These results show that: 1) mice with unaltered hepatic granulomatous reaction show reduction in metabolism of sodic pentobarbital; 2) granulomatous response diminished by azathioprine does not interfere with the capacity of metabolism of the anesthetic drug.

The friction force mouse-pad and the forearm muscles efforts (preliminary results)

The objective of the article is to evaluate the impact of the friction force mouse-pad in the contraction level of the forearm muscles M. extensor carpi ulnaris, M. extensor digitorum and M. extensor carpi radialis longus. A standard protocol of mouse movements was performed involving horizontal, vertical and diagonal mouse displacements drag-and-drop type. The operators were instructed to execute the protocol with their normal working speed. The movements protocol were performed by each subject (n=17) with three selected pairs mouse-pad, classified as low, medium and high friction force pairs. The mean time to execute the protocol with each mouse was ~138s. Mean values of ~13%MVE and ~17%MVE were found in the M. extensor carpi ulnaris and in the M. extensor digitorum respectively when performing the movements’ protocol. A 8.1% increase in %MVE was observed in the M. extensor digitorum and a 9.4% increase in %MVE was observed in the M. extensor carpi ulnaris when the high friction force pair was operated, relatively to the low friction force pair (p<0.05). The main preliminary conclusions of this study is that operating a high friction force mouse-pad may increase the risk to symptoms or disorders in the wrist due to an increase in the forearm muscles contraction levels, particularly during work with drawing application

Avaliação do Tratamento Cirúrgico da Artrose Trapeziometacárpica

The authors describe their experience, from July 1995 to December 1996, in the management of patients suffering from trapeziometacarpal degenerative arthrosis. Dell's classification is used for disease staging. The results of two different techniques are compared: 1) distal tenotomy of supranumerary insertions of abductor pollicis longus; and 2) trapeziectomy with tendon interposition arthroplasty and ligamentoplasty using the flexor carpi radialis.

A Rare Variant of the Ulnar Artery with Important Clinical Implications: a Case Report

BACKGROUND: Variations in the major arteries of the upper limb are estimated to be present in up to one fifth of people, and may have significant clinical implications. CASE PRESENTATION: During routine cadaveric dissection of a 69-year-old fresh female cadaver, a superficial brachioulnar artery with an aberrant path was found bilaterally. The superficial brachioulnar artery originated at midarm level from the brachial artery, pierced the brachial fascia immediately proximal to the elbow, crossed superficial to the muscles that originated from the medial epicondyle, and ran over the pronator teres muscle in a doubling of the antebrachial fascia. It then dipped into the forearm fascia, in the gap between the flexor carpi radialis and the palmaris longus. Subsequently, it ran deep to the palmaris longus muscle belly, and superficially to the flexor digitorum superficialis muscle, reaching the gap between the latter and the flexor carpi ulnaris muscle, where it assumed is usual position lateral to the ulnar nerve. CONCLUSION: As far as the authors could determine, this variant of the superficial brachioulnar artery has only been described twice before in the literature. The existence of such a variant is of particular clinical significance, as these arteries are more susceptible to trauma, and can be easily confused with superficial veins during medical and surgical procedures, potentially leading to iatrogenic distal limb ischemia.

Morfo-anatomia de sementes de Dipteryx odorata (Aubl.) Will. (Fabaceae) como contribuição ao estudo Farmacognóstico de plantas da região Amazônica

Dipteryx odorata (Aubl.) Willd. (Fabaceae) é popularmente conhecida como cumaru. Suas sementes são utilizadas pela população, por seus efeitos terapêuticos, dados pela cumarina, hoje comercializada para distúrbios vasculares e linfáticos e pela produção de óleo. Realizou-se um estudo morfo-anatômico de sementes de seis indivíduos desta espécie através da caracterização morfológica, determinação do peso da matéria fresca e das dimensões de 100 sementes, além de cortes histológicos transversais e longitudinais, considerando-se o tegumento e o embrião. A semente é oblonga, levemente comprimida na região do hilo. O tegumento seminal apresenta cutícula delgada e lisa, macroesclereídeos, osteoesclereídeos, mesofilo interno e membrana basal. O embrião constitui-se de dois cotilédones e o eixo embrionário retilíneo, formado por plúmula, epicótilo e radícula.

Restriction site-associated DNA sequencing, genotyping error estimation and de novo assembly optimization for population genetic inference.

Restriction site-associated DNA sequencing (RADseq) provides researchers with the ability to record genetic polymorphism across thousands of loci for nonmodel organisms, potentially revolutionizing the field of molecular ecology. However, as with other genotyping methods, RADseq is prone to a number of sources of error that may have consequential effects for population genetic inferences, and these have received only limited attention in terms of the estimation and reporting of genotyping error rates. Here we use individual sample replicates, under the expectation of identical genotypes, to quantify genotyping error in the absence of a reference genome. We then use sample replicates to (i) optimize de novo assembly parameters within the program Stacks, by minimizing error and maximizing the retrieval of informative loci; and (ii) quantify error rates for loci, alleles and single-nucleotide polymorphisms. As an empirical example, we use a double-digest RAD data set of a nonmodel plant species, Berberis alpina, collected from high-altitude mountains in Mexico.
