30° inclination in handles of plastic boxes can reduce postural and muscular workload during handling

CONTEXTUALIZAÇÃO:O manuseio de materiais está ainda presente nos setores industriais e é associado a lesões na coluna lombar e membros superiores. A inserção de alças em caixas industriais é uma forma de reduzir os riscos relacionados à tarefa, porém a posição e a angulação das alças, que são fatores importantes para o conforto e segurança durante o manuseio, são ainda pouco investigadas objetivamente.OBJETIVOS:Comparar o manuseio de uma caixa comercial e de protótipos com alças e avaliar seus efeitos na postura de membros superiores, atividade elétrica muscular e percepção de agradabilidade em diferentes empunhaduras durante manuseio entre diferentes alturas.MÉTODO:Trinta e sete voluntários saudáveis avaliaram as alças dos protótipos que possibilitavam mudança nas posições (superior e inferior) e angulações (0°, 15° e 30º). Os movimentos dos punhos, cotovelos e ombros foram avaliados por meio da eletrogoniometria e inclinometria. A atividade elétrica muscular dos extensores do punho, bíceps braquial e porção superior do trapézio foi avaliada por um eletromiógrafo portátil. Os registros de movimento e atividade elétrica muscular foram sincronizados. Aspectos subjetivos de agradabilidade foram avaliados por meio de uma escala visual analógica.RESULTADOS E CONCLUSÕES:Os protótipos com alças inclinadas em 30° apresentaram as melhores avaliações de agradabilidade, posturas mais neutras de punho, menores níveis de atividade eletromiográfica do trapézio superior e menores ângulos de elevação dos braços. Os diferentes métodos de medida se mostraram complementares para a avaliação dos membros superiores durante as tarefas de manuseio.

Estimativa do surto de crescimento puberal pela avaliação das vértebras cervicais em radiografias cefalométricas laterais

The aim of this research was to estimate the skeletal growth and development by observingradiographically the morphological changes of the first, second and third cervical vertebrae, according to the method proposed by Hassel &Farman32 (1995) in patients who were going through the outbreak of pubertal growth. The radiographic inspection of the cervical vertebrae was performed by means of cephalometric radiographs and the outbreak of pubertal growth was identified through the events of ossification of the hand and wrist. For that purpose, we selected thecephalometric radiographs and hand•wrist radiographs of 110 Brazilianleukoderms, male and female,with chronological age ranging from 8 to 14,6 years old for the girls and from 9,5 to 15,4 years old for the boys.The results showed that there was a statistically significant correlation between the maturation indicators of the cervical vertebrae and the patients who were going through the outbreak of pubertal growth. The conclusion was that the radiographic evalution of the changes of the cervical vertebrae, in the cephalometric radiographs, is an alternative parameter, which is reliable and practical in the skeletal evalution, and the it completes the range of information that must be obtained from the patient under orthodontic treatment and that it can, circumstantially, replace other methods of evalution

O controle de preensão em pinça em adultos jovens: efeito da posição do punho

The human hand is the focus of inumerous research studies. Human individuals are capable of performing manual tasks beyond the ability of any other animal. Such large motor ability is due in part to contact surface of the pulp thumb in opposition to the other fingers. Evidences in the literature show that the position of the upper limb influences the ability of hand strength and control. Specifically, the position of the wrist has great influence on the production of pinch strength. The main objective of this study was to investigate the influence of wrist position on the pinch grip with the thumb in opposition to the index finger. Participants of the present study were 21 undergraduate students, 10 men and 11 women. Participants performed a pinch grip task in three wrist positions - maximum flexion, maximum extension and neutral - on two force conditions - 20% and 40% of maximum voluntary contraction (MVC). MVC was measured in two attempts in each of the three positions of the wrist for a period of three seconds, and the trial of the best result was used as the parameter for task performance. In each trial participants maintained the force production at position for 10 seconds. All participants performed each test condition four times, and the first was used as a familiarization trial and discarded from further analysis. In all trials visual feedback online was provided. Results of both group gender showed variability was similar for force production. Men were stronger than women, but this difference was not significant and both produced on the average more strength in the neutral wrist position than in flexion or extension. In the extended position participants were significantly less variable than in the flexion and neutral positions. We obtained a significant positive correlation between weight and pinch force...(Complete abstracts click electronic access below)

Rerrefino de óleo lubrificante usado

The lubricant oil used in engines of internal combustion must be, periodically, changed. Its mainly function in the engines is to reduce the friction between the pieces, but its presence also promotes the cleanness and the refrigeration of the equipment. These attributions, at the end of some cycles of operation, make the oil to be dirty, that is, full of contaminating substances such as water, gasoline, diesel, additives, oxidized hydro-carbons and rests of metals, not being recommended, therefore, its discarding in the environment. Thus, all the used lubricant oil that leaves the automobiles engine has been thrust, waiting for a solution. The pollution generated by the discarding of a ton of used oil per day in the soil or in the rivers is equivalent to a domestic sewer of 40 thousand of people. The indiscriminate burning of the used lubricant oil generates significant emissions of metallic oxides, besides other toxic gases, like the dioxin and sulphur oxides. In this context, the mean objective of this essay was to effectuate the rerrefine of the used lubricant oil, aiming the increase of its life cycle and consequently contributing for the reduction of the environmental pollution. According to the used process, it was possible to get a rerrefine oil, of good quality, which physicistchemistries properties are in compliance with the norms of NBR and ASTM

Comparação de dois métodos de profilaxia dental: avaliação da pressão arterial e do conforto do paciente. Ensaio clínico controlado e randomizado

GOALS: This research evaluated the change in arterial pressure before and after two procedures of dental prophylaxis: Jet system baking soda and conventional prophylaxis and patient's opinion regarding the comfort of each one. MATERIAL AND METHOD: Were selected 32 patients with age between 18 to 30 years old, who need prophylaxis to remove biofilm and were subjected to three different types of treatment: sodium bicarbonate jet (G1), prophylaxis conventional (G2) and placebo (G3) at intervals of one month between them. Patients were divided randomly. Arterial pressure was measured by wrist digital Omron HEM – 6111. The measurements were realized in four times: before the prophylaxis, immediately the end of procedure, 15 and 30 minutes after finished of treatment. Patient comfort was measured by a Visual Analog Scale (VAS) after the end of the treatment. The data were analyzed using the variance test. The results showed that there was statistically significant difference to the comfort of the procedures. RESULTS: There was a statistically significant difference to the comfort of the procedures, and G2 and G3 better than G1. Regarding the variation of arterial pressure there was no statistically significant difference between groups. CONCLUSIONS: The methods of prophylaxis no effect on arterial pressure, but conventional prophylaxis is more comfortable than others treatments

Análises de solos e sedimentos de corrente, nas áreas das usinas de fundição de chumbo do Calabouço (CIEM-CPRM) e de beneficiamento de minério aurífero do Morro do Ouro (Parque Municipal Morro do Ouro), no município de Apiaí - SP

Located in Apiaí, Vale do Ribeira, southern region of São Paulo state, the Usina do Calabouço areas (CIEM / CPRM) and Morro do Ouro (Parque Municipal do Morro do Ouro), were targeted for stud ies due to its old buildings, respectively a foundry in lead ore, called Experimental de Chumbo e Prata (Usina Calabouço), and a gold mine with processing plant of the gold-bearing ore produced there. Nowadays, the areas are used for public visitation, and in both places the rests of the buildings remains. Particularly in the CIEM/CPRM, due to the materials witch was produced before, it can suggest the existence of anomalous amounts of the involved metals (CIEM / CPRM) and possible contaminations by chemical products used in the improvement of the auriferous ore (P. M. Morro do Ouro). These potential contamination were confirmed with geochemical survey of soils and current sediments accomplished in both areas, for the elements arsenic, cadmium, lead, copper, mercury, silver and zinc, which were used as parameters guiding values for soil and groundwater the state of São Paulo (CETESB), and watershed values stipulated by CPRM (poor, background and anomalous), in it rising geochemistry during Folha Apiaí's execution (SG-22-X-B-V).
