TENSILE AND CREEP BEHAVIOR OF GEOSYNTHETICS USING CONFINED-ACCELERATED TESTS

A major aspect in geosynthetics creep analysis is the load level applied to the specimen, usually referred as a percentage of the geosynthetic ultimate tensile strength (UTS). Since both tensile and creep standard tests are performed with in-isolation specimens, they may not reproduce the possibly significant effect of soil-geosynthetic interaction. A new creep testing machine was recently developed and successfully addressed this concern. However, further developments allowed tensile tests to be performed in the same conditions used in nonconventional creep ones. This paper presents the results of nonconventional tensile tests performed with a woven biaxial polyester geogrid. They were used to define its UTS in the same conditions employed in creep tests performed with the new equipment. Despite changes in tensile curves shapes were found, the UTS from confined, accelerated and confined-accelerated tensile tests were quite similar to those obtained with standard tensile test procedure.

Brazilian adaptation of the Woodcock-Johnson III cognitive tests

An adaptation of the standard battery of Woodcock-Johnson III Tests of Cognitive Abilities (WJ-III) for Brazilian children and youth was investigated. The sample was composed of 1094 students (54 percent girls), ages 7-17, living in Sao Paulo state (91 percent). Items from Brazilian school books as well as from the WJ-III Spanish version (Bateria-R) were added to comprehension-knowledge tests. Brazilian words were adapted to the auditory tests according to syllabic division and stressed syllables. Items were examined through IRT and age differences through analysis of variance. Results indicated the need to remove items from all WJ-III subtests with the exception of the visual learning test. Analysis of Variance indicated significant age differences (p <= 0.001) for all tests. Thus, the importance of a Brazilian adaptation for the WJ-III was confirmed.

Atividade física e sintomas depressivos em cuidadores de idosos com demência de Alzheimer

The Alzheimer's dementia (AD) is a chronic, neurodegenerative and progressive disorder, characterized by cognitive decline, affecting brain functions like memory, reasoning and communication, occurrence of behavioral disturbances and difficulty in performing activities of daily living (ADLs). These conditions lead to patient’s dependence, which can cause depressive symptoms in caregivers, due to physical and mental burden caused by of the difficulties of the act of caring. Whereupon, it became necessary to find strategies to improve the caregivers’ quality of life. An interesting hypothesis is that physical activity can be considered a non-pharmacological alternative in reducing depressive symptoms, being an important factor for maintaining the physical and mental well-being of the general population, especially on positive changes in mood and social interaction. This study aimed to analyze the effects of a physical activity protocol on depressive symptoms and burden of caregivers of patients with AD. This experimental study, of longitudinal character, comprised a sample of 19 caregivers, of both genders, divided into two groups: a) intervention group – IG (10 caregivers who participated in a physical activity protocol) and b) control group – CG (9 caregivers who didn’t participate in the physical activity protocol). This protocol, which worked the components of functional ability and social interaction of participants, was held three times a week, being 48 sessions of 60 minutes each, for 16 weeks. Data collect was performed at pre and post-intervention for both groups. The assessment instruments used were: a) Zarit Burden Interview, b) Hospital Anxiety and Depression Scale (HAD) and c) battery of motor tests of the American Alliance for Health Physical Education Recreation and Dance (AAHPERD). Nonparametric statistics was used, with intra-group comparison by Wilcoxon test... (Complete abstract click electronic access below)

Efeitos do treinamento com pesos nas atividades de vida diária básicas e instrumentais de pacientes com doença de Alzheimer

The Alzheimer's disease (AD) is a neurodegenerative and progressive disease, mostly seen in elderly people, characterized by memory loss. This commitment leads causes deficits in functional capacity, compromising the individual in execution of activities of daily living, like dressing and bathing. This study, with a longitudinal character, aimed analyze the effects of a protocol of weights training (WT) in global cognitive status and realization of activities of daily living (ADL´s) basic and instrumental in AD patients, comparing the effects of four months of WT in the performance of ADL´s in global cognitive status. And also aimed to verify the possible relations between ADL's and global cognitive status of patients before and after the experimental period. The study included 24 patients with clinical diagnosis of AD, divided into two groups: a) training group (TG) consisted of 13 patients who underwent a protocol of WT b) Social Gathering Group (SCG) consists of 11 patients participating in a protocol of social gathering not systematized with activities of reading, writing and walking. Both protocols lasted four months, being developed in three non-consecutive weekly sessions, lasting 60 minutes each. To quantify global cognitive status and the basic and instrumental ADLs were used, respectively, the Mini-Mental State Examination and the Self Perception of Performance in Activities of Daily Living, along with the battery of tests of Activities of Daily Life of Andreotti and Okuma (1999). To analyze the results where complied the nature of the data, using analysis of variance for repeated measures ANOVA two-way and Pearson correlation for continuous data and tests of U Mann Whitney, Wilcoxon and Spearman correlation for non-continuous data, assuming level significance of 5% for all analysis. After analysis it´s possible... (Complete abstract click electronic access below)

Stability of a Lipase Extracted from Seeds of Pachira aquatica in Commercial Detergents and Application Tests in Poultry Wastewater Pretreatment and Fat Particle Hydrolysis

A protein extract containing a plant lipase from oleaginous seeds of Pachira aquatica was tested using soybean oil, wastewater from a poultry processing plant, and beef fat particles as substrate. The hydrolysis experiments were carried out at a temperature of 40°C, an incubation time of 90 minutes, and pH 8.0-9.0. The enzyme had the best stability at pH 9.0 and showed good stability in the alkaline range. It was found that P. aquatica lipase was stable in the presence of some commercial laundry detergent formulations, and it retained full activity up to 0.35% in hydrogen peroxide, despite losing activity at higher concentrations. Concerning wastewater, the lipase increased free fatty acids release by 7.4 times and promoted the hydrolysis of approximately 10% of the fats, suggesting that it could be included in a pretreatment stage, especially for vegetable oil degradation.
