The Alzheimer’s dementia represents a clinical condition inherent to many chronic and neurodegenerative diseases that are usually related to a decline in the cognitive and physical functions. The objective of this experimental design research was to analyze the effects of a regular and systemized physical activity program over the cognitive functions, balance and risk of falls of elderly with Alzheimer’s Dementia (DA). The sample was made of 16 elderly with DA, distributed in two groups: a) intervention group – GI (9 subjects that had participated in a program of physical activity, that consisted of 3 weekly sessions of 60 minutes each, in alternated days and with a duration of 6 months); b) control group – GC (7 subjects that did not participate in the program of physical activity). Both groups maintained the doctoral and pharmacological assistance routine. The subjects passed through two different evaluations (pre and post-intervention) the questionnaire (Mini-exam of Mental State for cognitive functions) and motor tests (Berg Functional Balance Scale – EEFB, Timed Up-and-Go (TUG) time (TUGs) and steps (TUGp) and the test of agility and dynamic balance (AGILEQ) of the American Alliance for Health, Physical Education Recreation and Dance for elderly). The obtained results were, respectively in the pre and post-intervention moments: a) AGILEQ (GI = 39,1 ± 10,2 and 38,4 ± 8,9 and GC = 45,6 ± 16,7 and 59,9 ± 22,0 seconds) with the statistically interaction significant (ANOVA two-way; F1,14 = 32,07; p=0,01) between groups and moments; b) TUGs (GI = 9,8 ± 2,5 and 9,5 ± 3,3 and GC = 10,6 ± 4,5 and 12,7 ± 7,3 seconds) the test UMann Whitney did not appoint any significant differences between the groups in the post-intervention moment, however the analyzes of Wilcoxon evidenced a ...(Complete abstract click electronic access below)

Millipedes are macro-arthropods of soil which perform a important role in maintaining the balance of the ecosystem, since they feed on decaying organic matter and because they promotes the soil enrichment, aeration and humidification. These animals are usually found in humid with low light places, under rocks and trunks. The diplopods exoskeleton is much resistant and impregnated with calcium salts. Due the secretion of defense, with strong and unpleasant smell, the animals of this class have few or no predators. Large diplopods populations are not observed, but explosions population can occur for unbalances enviromnmental, by climate change and by use of pesticides that may eliminate potential competitors. In this sense, the millipede Urostreptus atrobrunneus Pierozzi & Fontanetti, 2006, has presented points of infestation in urban centers of Sao Paulo state, causing many disorders of the human population. Because it is a newly described species, little is known of its aspects biological and morphological. Thus, the purpose of this study was to describe the structure and function of the digestive tract of the species U. atrobrunneus by means of histological, histochemistry and ultrastructural techniques. The results demonstrated that the digestive tract of U. atrobrunneus is similar to the descriptions given for other species. The foregut consists of a simple epithelium, composed of cells of different heights, covered by a cuticular intima, leaning on a thin basal membrane, followed by a well-developed muscular layer and an external membrane, around the foregut have a pair of salivary glands. The midgut epithelium has a pseudostratified, supported by a thick basal membrane, followed by a muscular layer and a layer of hepatic cells. The muscle is distributed unevenly coated with an external membrane, this portion is marked by the absence of cuticular intima... (Complete abstract click electronic access below)

With the popularization of information technology and government incentives for inclusion in the digital era, an important issue for science and for industry is the design of tool s for entrance of input to the device, that is , the peripherals at tached to the computer that are reaching the consumer. In order to minimize the impact of repetitive use of these tools for entry, whether when playing games or working, more studies are in need to developper ipherals that enable comfort and effi ciency. This study examined the per formance of individuals with differents izes of hand (i.e., large and small ) in performance of three task s on the computer us ing mouses of small and large sizes. For thi s study, 19 young adul ts were volunteers and asked to per form activities with greater precision and speed. In addition, al l participants were asked on the use of computers. The results showed no statistically significant differences in the performance related to the size of the mouse between subjects with small and large hands. However, an interest ingresult as observed with respect to the performance of individuals with a large hand to perform tas ks more quickly. The results of this study suggest that with both, the small and the large mouse, individuals with big hands have a fas terper formancein tasks of dragging and clicking when compared with the performance of indi viduals with small hand.

This paper attempts to answer how the descriptive analysis of the substantive subordination clauses made within the realm of academic research can contribute to the effective teaching of those structures in the Elementary School. After showing how the subordination has been treated in grammar school and textbooks and pointing at some recurring problems in the presentation of the subject, we present the treatment of subordinate clauses with the function of subject in two descriptive grammars of Portuguese, in order to ascertain to what extent the relevant aspects of the description of those clauses are related to the traditional way of teaching. From those descriptive works, we selected some functional features considered to be essential for the treatment of the subject in the Elementary School.

Neste artigo descrevemos o comportamento de orações subjetivas e objetivas diretas nas fases arcaica (séculos XIII a XV) e moderna (séculos XVI e XVII) do português. Adotamos o quadro teórico da gramaticalização e dessentencialização de orações e discutimos resultados para os parâmetros tipo semântico do predicado matriz, unidade semântico funcional representada pela oração encaixada e formato da oração encaixada. Observamos, ao longo das sincronias, correlações sistemáticas entre os parâmetros investigados para os dois tipos oracionais. Orações subjetivas apresentam menor variedade de padrões do que orações completivas objetivas, principal diferença a interferir em suas estabilidades sintático-semânticas nos períodos investigados.

This paper addresses the single stage lot-sizing problem in parallel machines. Each item can be produced on any machine, and incurs a setup time before to start the production. The objective of this paper is to obtain lower bounds of good quality for this problem. A solution method is developed based on a reformulation of the problem and the Lagrangian relaxation of a set of constraints. Some computational results are presented comparing the proposed method with a method from the literature and with a computational package.

A monitoring network of atmospheric electric field covering the Vale do Paraiba region was implemented. The sensors were located on different sites with different altitude and geographic topology. The present work reports the study carried on those sensors in order to verify the necessity of using some correction factor to the measured local electric field intensity due to effects of local environment. The measurements were done in continuous 24 hours per day with the data recorded on registers in each device accumulating information during a period of four months. The relation between the electric field values by each sensor was compared to the reference located on Sao Jose dos Campos city using the same period. In a graphical analysis using the local field intensity and the reference, the data were fitted to a straight line obtained by minimum square method. Variation up to 95% was observed between the field values in some sensors. Another method was proposed, comparing the mean values of the electric field in a function of time. The variation in some sensors reached up to 133%. We conclude that the variations are due to local atmospheric conditions and no correction factor is required on the electric field sensors
