Efeito agudo de diferentes volumes de alongamento estático na contração voluntária máxima de idosas

Several studies have shown that different stretching routines can lead to decreases on acute neuromuscular system performance. Although the deficit in muscle strength mediated by different methods of stretching has been systematically observed, few studies have investigated the possible existence of a dose-response relationship between the amount of stretching and muscle strength deficit in older adults. In this context, the objective of this study was to investigate the acute effect of two different stretching volumes on isometric force-time curve (Cf-t) in elderly women. The study included 13 older women (64.08 ± 4.27 years, 69.98 ± 10.56 kg, 157.90 ± 8.66 cm, 28.25 ± 4.22 kg/m²). The participants visited the laboratory for five consecutive days, among which the first two were used for familiarization. During the other three days the participants underwent experimental conditions: control (C) stretch 30 seconds (AE30) and stretch 60 seconds (AE60). For the AE30 and AE60 conditions, three series of passive static stretching were performed, with duration of 30 and 60 seconds, respectively. The experimental conditions were performed with an interval of at least 24 hours between them and the order of execution was randomized. The recording of isometric Cf-t of the knee extensor muscles was performed in extensor chair connected to a force transducer. Measurements were recorded immediately after each experimental condition, for five seconds. For statistical analysis, descriptive procedures were used and ANOVA one way to check possible changes on the Maximal Voluntary Contraction (CVM) and Peak Rate of Force Development (TDFP) among the three conditions (p <0.05). The ANOVA showed no statistically significant difference for CVM and TDFP, between the three conditions. It can be concluded that different volumes of static stretching, three sets ...(Complete abstract click electronic access below)

Estudo e análise do risco e da viabilidade econômica do mercado cativo e do mercado livre de energia elétrica no terceiro ciclo tarifário

In 2004 two trading environment for contracts of purchase and of electricity energy were established, the Regulated Contracting Environment (RGE) and the Free Contracting Environment (FCE). In the first one, consumers can only buy their energy directly from local electricity distribution, and in the second one, consumers can choose their delivery, amount and type of energy that they will burn through bilateral contracts. Thus, before deciding to migrate to the FCE, it is necessary understanding the rules of marketing, the risk involved and the economic viability of the two markets so can determine which environment has more benefits to the consumer. This paper aims to offer tools to support takeover decision of potentially free costumers, who have the option to migrate to market in order to evaluate the benefits and disadvantages of each market. This paper has also considered the new rules of the third rate cycle, where consumers can opt for green tax. The methodology presented is based on calculations of spending with energy and the risk of flag in captive market and free market in one year

MR-Radix: a multi-relational data mining algorithm

Background: Once multi-relational approach has emerged as an alternative for analyzing structured data such as relational databases, since they allow applying data mining in multiple tables directly, thus avoiding expensive joining operations and semantic losses, this work proposes an algorithm with multi-relational approach. Methods: Aiming to compare traditional approach performance and multi-relational for mining association rules, this paper discusses an empirical study between PatriciaMine - an traditional algorithm - and its corresponding multi-relational proposed, MR-Radix. Results: This work showed advantages of the multi-relational approach in performance over several tables, which avoids the high cost for joining operations from multiple tables and semantic losses. The performance provided by the algorithm MR-Radix shows faster than PatriciaMine, despite handling complex multi-relational patterns. The utilized memory indicates a more conservative growth curve for MR-Radix than PatriciaMine, which shows the increase in demand of frequent items in MR-Radix does not result in a significant growth of utilized memory like in PatriciaMine. Conclusion: The comparative study between PatriciaMine and MR-Radix confirmed efficacy of the multi-relational approach in data mining process both in terms of execution time and in relation to memory usage. Besides that, the multi-relational proposed algorithm, unlike other algorithms of this approach, is efficient for use in large relational databases.

Desenvolvimento, implantação e avaliação do desempenho de biorreator anaeróbico de leito fluidizado e leito fixo com filtros biológicos em materiais diversos

This study aimed to develop, implement and evaluate the performance of a new type of bioreactor for anaerobic treatment of wastewater using different filling materials like trickling filters post-reactor. This bioreactor has mixed characteristics of the UASB reactors and horizontal flow from the point of view of removal of BOD (Biochemical Oxygen Demand) ssed (settled solids), TS (Total Solids), SS (Suspended Solid), SD (Dissolved Solids) and turbidity. The experimental model consists of a bioreactor with a volume of 12 m³, 2/3 filled by fluidized bed and 1/3 for fixed. The fluidized bed is made of polystyrene plates used as a system percolation and compartmentalized trickling filters, where each compartment was filled with a support medium with different characteristics (gravel number 4, plastic rings of polystyrene, PET and HDPE) . In addition, the output of a filter system was installed three entries filled with activated carbon. The bioreactor was installed in private residence in the city of Igarapava-SP (20° 02'40.18"S and 47° 45'01.36" W). The system was highly efficient as the removal of organic contaminant load 92% on average reducing the BOD, a significant result when compared to other anaerobic systems. For the other parameters, the mean reduction was 96% for turbidity, 99% ssed, 67.5% ST, 57% SD and 88% of SS. As for its operation the system was capable of operating in continuous flow without the need for maintenance during the entire period of evaluation and without energy, as it operates taking advantage of the natural slope of the terrain where it is installed. The environmental impacts were minimized due to the preservation of local vegetation allowing the ecosystem to remain unchanged beyond the prototype was completely sealed preventing exhalation of odors and therefore not causing inconvenience to neighboring populations. Given these facts it was concluded that the prototype is shown to be highly feasible deployed as a new alternative for treatment of sewage in rural and urban settings (individual homes, condos, farms, ranches, etc.) Due to ease of design and operability, and sustainability at all stages of execution.

Efeito agudo do alongamento de diferentes grupos musculares no desempenho muscular de idosas

Among the numerous possibilities of physical exercise, it has been recommended that stretching routines should be incorporated into training programs focused on the elderly population, and that these routines should be preferentially performed on the same strength or aerobic training session. However, studies have shown that muscle strength production can be acutely impaired if it is preceded by static stretching exercises (AE). Although there seems to be a relationship between the number of stretched muscles and strength response, no studies were found examining such relationship in the same study, simultaneously. Thus, the objective of this study is to analyze the acute effect of stretching of different muscle groups on strength performance in older women. Nineteen physically active older women participated in the study (67.8 ± 5.3 years, 68.9 ± 12.4 kg, 157.2 ± 6.4 cm)-usar ponto final em inglês e não vírgula. The participants visited the lab for six consecutive days, three of which were intended to familiarization. Over the next three days, all the participants performed the experimental conditions: control; quadriceps stretching alone and complete stretching, involving the major extensors muscle groups of knees and hips. Both the two stretching conditions were realized with three series of 30s (total volume of 90 seconds for each exercise). All experimental conditions was be performed with an interval of at least 24 hours and order of execution was be randomized. The force transducer was connected to a leg press apparatus, where the isometric force time curve and electromyographic activity of the vastus medial and vastus lateralis were recorded. Measurements were registered immediately after each experimental condition, during five seconds. Statistical analysis comprised descriptive procedures and the One way ANOVA test for repeated measures (p<0.05). No statistically significant differences between the control and the two...

Sofrimento psíquico e trabalho intelectual

This study aims to understand if intellectual work provides conditions for the emergence of psychic suffering inuniversity teachers in a public institution of higher education. Use is made of the philosophical assumptions ofhistorical materialism, work as a category of nuclear analysis of human phenomena, and also the categories ofalienated labor and intellectual work. It also refers to mental illnesses as a social production. The research subjectswere teachers with contracts of employment in exclusive dedication (RDIDP). It is used as an instrument for datacollection, a questionnaire with closed and opened questions of opinative character. Responses were categorized andanalyzed qualitatively and had not intention of giving statistical data. However, in order to better display, the samepercentage of the sample are presented, among which one third (29.6%) have some health problem after enteringuniversity. Of those, 15,5% are related to the organization of work, 5,6% to the working conditions, 2,8%concomitantly to the conditions and the organization of work. The results indicate that the organization of work in apublic university has shown itself as a space of psychic suffering, but also of alienation.

The influence of the flexibility of the chair seat on pressure peak and distribution of the contact area in individuals with cerebral palsy during the execution of a task

This study aimed to determine the influence of flexibility of the chair seat surface on the pressure peak and on the contact area during the execution of a task of handling an object on the seated position by individuals with spastic cerebral palsy. Ten individuals of both genders with diagnosis of spastic cerebral palsy, who had some control to voluntarily move the body and the upper limbs, participated in this study. Quantification of data was carried out in two experimental situations: (1) execution of a task of fitting with upper limbs, and with the individual placed on an adapted canvas seat; (2) execution of a task of fitting with the participant positioned on an adapted wooden seat. Data obtained were submitted to a non-parametric and descriptive statistical analysis using the Wilcoxon test. Results indicated that the use of canvas seat increased the contact area and decreased the pressure peak and the medio-lateral displacement of centre pressure on the seated posture. © 2011 Informa UK, Ltd.
