Modificações na produtividade e nas características físicas e químicas da madeira de Eucalyptus grandis causadas pela adubação com lodo de esgoto tratado

O Eucalyptus grandis é uma das espécies mais cultivadas no Brasil devido à sua produtividade e qualidade da madeira. Avaliaram-se o efeito da aplicação de lodo de esgoto tratado (0 a 40 t ha-1 base seca) e uma dose de adubo mineral nos atributos físicos e químicos da madeira de Eucalyptus grandis de árvores com cinco anos de idade, no Município de Itatinga, São Paulo, Brasil. O tipo de solo foi caracterizado como Latossolo Vermelho-Amarelo Distrófico (argila = 120 g kg-1 na camada de 0-20 cm) e o clima, como mesotérmico úmido (Cwa), segundo a classificação de Köeppen. O delineamento experimental foi o de blocos ao acaso, com seis tratamentos e quatro repetições. O diâmetro à altura do peito (DAP), a altura das árvores e o volume de madeira foram obtidos em todas as parcelas de oito árvores com DAP na classe de maior freqüência. As caracterizações físicas e químicas da madeira foram realizadas de acordo com as normas da ABTCP, TAPPI e ABNT. O lodo de esgoto diminuiu a densidade básica da madeira, mas não afetou os teores de celulose, lignina, extrativos e o poder calorífico da madeira. O decréscimo de densidade da madeira pela adubação com lodo de esgoto foi compensado pela maior produtividade de madeira.

Análise fractal da vasculatura arteriolar e venular da retina em pessoas sem doença ocular

Although it has been suggested that retinal vasculature is a diffusion-limited aggregation (DLA) fractal, no study has been dedicated to standardizing its fractal analysis . The aims of this project was to standardize a method to estimate the fractal dimensions of retinal vasculature and to characterize their normal values; to determine if this estimation is dependent on skeletization and on segmentation and calculation methods; to assess the suitability of the DLA model and to determine the usefulness of log-log graphs in characterizing vasculature fractality . To achieve these aims, the information, mass-radius and box counting dimensions of 20 eyes vasculatures were compared when the vessels were manually or computationally segmented; the fractal dimensions of the vasculatures of 60 eyes of healthy volunteers were compared with those of 40 DLA models and the log-log graphs obtained were compared with those of known fractals and those of non-fractals. The main results were: the fractal dimensions of vascular trees were dependent on segmentation methods and dimension calculation methods, but there was no difference between manual segmentation and scale-space, multithreshold and wavelet computational methods; the means of the information and box dimensions for arteriolar trees were 1.29. against 1.34 and 1.35 for the venular trees; the dimension for the DLA models were higher than that for vessels; the log-log graphs were straight, but with varying local slopes, both for vascular trees and for fractals and non-fractals. This results leads to the following conclusions: the estimation of the fractal dimensions for retinal vasculature is dependent on its skeletization and on the segmentation and calculation methods; log-log graphs are not suitable as a fractality test; the means of the information and box counting dimensions for the normal eyes were 1.47 and 1.43, respectively, and the DLA model with optic disc seeding is not sufficient for retinal vascularization modeling

Apitidão funcional e comportamentos relacionados à saúde em mulheres idosas do município de Jequié-BA

The identification of the factors that interfere in the decline of functional conditions is useful in the planning of actions addressing the improvement in the conditions of the lives of elderly people. The purpose of this investigation was to analyze the relationship between social demographics and health aspects of the functional condition in elderly women of low income of the Brazilian northeast. This crosssectional study involved a representative sample of 222 women with an average age of 70 years (± 7.1), belonging to coexisting groups and that were resident in the urban area of the municipal district of Jequié /Bahia. In order to achieve this objective, a battery of physical tests of functional aptitude was carried out previously tested in pilot study, anthropometric measurements collected with a comparison of the measures referred to the reported weight and height as well as the application of an interview with questions containing subjects related to social demographic variables, clinical conditions and health, physical conditions and behaviors. Descriptive statistics Proceedings (frequency, average, standard deviation and percent distribution) were used for statistic analysis, and the calculation of the respective odds ratio by binary logistics regression, for the analysis of factors hierarchically grouped; p<0.05. The prevalence of 56% (n=122) of women considered with moderated or serious type of functional limitations was found, In which from multi-varied hierarchical analysis, significant association was verified with the age group over 80 years (p=0.02), conditions of widowhood (p=0.04), presence of arterial hypertension (p=0.001), and physical inactivity during leisure time (p=0.03). On the other hand for functional incapacities the prevalence was of 46.8% (n=104) being associated to the increase of the age (p=0.01), hospitalization (p=0.02), absence of physical activities along their lives (p=0.001) and the occurrence of alterations in the cognitive function (p=0.001). The normative table for the parameters of physical fitness generated conducive to health professionals in the diagnosis of health conditions and the prescription of physical exercises. The identified characteristics that are associated with the functional limitations / functional incapacities suggest a complex causal net in the determination of the functional condition in elderly women. However, actions addressed to the incentive of the practice of physical activities in the leisure time and the preservation of the cognitive function can contribute to a life with more quality for these people. This research was multidisciplinary approach to involve elements of psychology, nutrition and Physical Education in the elucidation of the object of study related to the functional condition of elderly women

A saúde psíquica de quem faz saúde: uma análise crítica sobre a humanização direcionada ao profissional de saúde

It is noticeable that pressure, tension and overwork are frequent in health professionals routine. The work related to the ward area demands deep attention and surveillance. Because of that, it is essential to have a specific look at the humanization directed at health professionals, considering that taking care of other human beings is the essence of their job. This study has analyzed the psychic health levels, as well as the stress health professionals are submitted to, providing a debate about the humanization in 06 public hospitals (03 of them awarded by actions of humanization, and 03 not awarded) in Rio Grande do Norte state, Brazil. A study with 126 active health professionals (doctors, nurses, psychologists, nutritionists and social workers) in ward areas in their respective institutions was carried out. The thesis presented, with multi-disciplinary characteristic, counted on the support of statisticians (to calculate samples and data analysis), psychologists, social workers and administrators (linked to the human resources sector in each hospital). A cross-sectional study was performed, taking into consideration both quantitative and qualitative factors. The tools used for that were a semistructured questionnaire with socio-demographic characteristics, work and humanization; Lipp's Stress Symptoms Inventory for Adults (ISSL), and the Goldberg s General Health Questionnaire (QSG). The workers are predominantly women (84,9%), married (54,8%), between 46 and 55 years old (40,5%), working in the same institution for more than 20 years (22,2%), and between 16 and 20 years (20,6%), respectively. They work 40 hours a week (71,4%) and have multiple jobs (61,9%). Although most of these individuals global psychic health is in a good level, there are a significant number of people that is gradually getting worse concerning psychic stress (F1) showed by QSG (54,7%), and stress showed by ISSL(42,1%). Observing the categories, nurses (41,5%). Nutritionists (20,8%), doctors and social workers (18,9%), were among the most affected. About general health (F6), 63% of the awarded hospitals and 70% of the not awarded ones, presented good health levels (ranging from 5 to 50%). It was also noticed that, in the groups mentioned above, 25 and 20% respectively, were inserted in scores between 55 to 90%, what means that they are in worsening phase. The fact that the hospital is awarded or well recognized doesn t interfere in health professionals stress level and in their psychic health. Through what was heard from these individuals, it was possible to verify that they know little about humanization, once few of them identify or know that the service they offer is in an adoption process by Ministerial Policies. It was also detected the necessity of developing actions aimed at worker s health. Such results showed the importance of have more investments in programs that are directed to workers well-being, because they deal with other people s health and it is known that it is difficult for them to offer high-quality assistance if there are not suitable physical, psychological and material conditions to help them develop their jobs. As a warning, it is fair to say that investments in actions that provide humanized care to health professionals, mainly concerning preventive care for their health and life quality in their work

Voleibol infanto-juvenil brasileiro: Somatotipia, qualidades físicas e marcadores genéticos dos atletas em diferentes níveis de qualificação esportiva

The elaboration of profiles with characteristics that can be parameters in the different categories of sports modalities and the investment in scientific studies have revealed a significant importance in the development of new generations of athletes. Based in the exposed, the purpose of this study was to identify and compare the somatotype characteristics, physical qualities and genetic markers of Brazilian male volleyball players in the 14-17 category playing at different levels (international, national and regional). We used a scale, stadiometer, pachymeter, and adipometer to evaluate somatotype, attack and block reach test, medicine ball toss, 30-meter agility test , the AAHPER -30 test to evaluate basic physical qualities and the dermatoglyphic method to identify genetic markers. The results show the superiority of the national team over the other squads in the somatotype component (ectomorphy), and in the level of basic physical qualities. We found no significant difference in genetic markers among the teams studied. We conclude that Brazilian volleyball players at different performance levels have characteristics peculiar to the sport, with height and physical qualities being significantly different among these teams. The results confirm de necessity of knowing the athletes specific characteristics when dealing with high performance teams using nutrition, medicine, physiology and genetics specific knowledges to achieve a better sportive development

Marcas dermatoglíficas, Antropometria e as qualidades físicas básicas dos escolares da rede municipal da cidade de Manaus

The objective of this study of comparative descriptive character went aimed at to analyze the characteristics dermatoglyphics, anthropometrics and the basic physical qualities, in 180 selected scholars in a stratified way, distributed like this: 10 year-old boys = 32; 09 years = 32; 08 years = 32; 10 year-old girls = 28; 09 years = 28; 08 years = 28), studying the fundamental teaching of the School Good Municipal Hope, located in the area east, in the Neighborhood of the Crowned, in the city of Manaus, Amazon. For identification of the dermatoglyphics characteristics collected, was the fingerprints; for evaluation of the corporal mass, height and IMC, they were used a digital scale with an estadiometer of the mark Filizola. The tests: to sit down and to reach flexibility); Horizontal Impulse or I jump in distance stopped (force of inferior members); Flex and extension of the trunk (it Forces abdominal); Flexion and extension of the arms in suspension in the bar (Force of superior members); 30 meters (Speed) and 9 minutes (Resistance applied aerobic) was to evaluate the basic physical qualities. The results demonstrated that differences didn't exist among the goods, in most of the studied variables, and the existent differences among the ages of 8, 9 and 10 years, they demonstrate a normality tendency in the infantile development

Dança Folclórica: um estudo das qualidades físicas básicas em universitários de diferentes níveis técnicos

Health and life quality can be preserved and improved by the regular practice of physical activity. Sedentarism is an undesirable condition and represents risk for the health. This study has as objective to analyze the caloric cost and the basic physical qualities in college students of different technical levels. The research was descriptive and applied to 35 students, volunteers, from 19 to 34 years old, from both sexes, participants of the Dance Body of State University of Piauí, in the city of Teresina, in the activities of folkloric dance and walking. The caloric cost was evaluated with the accelerometer Caltrac 100/100 Plan, the basic physical qualities through the sitting and reaching test (flexibility); the vertical impulsion test, crouch (inferior members strength); the abdominal test (located muscular resistance); and the Burpee test (motor coordination). The participants were separated in two groups according to their time of practice: group 1 (beginners), group 2 (advanced). The parametric tests t by Student and correlation by Pearson were used, observing a significance p<0,05 in the sense of comparing the observed results, which showed that there are no significant differences between the two groups of students, according to the time of practice, in which concerns the caloric cost. The results of Strength, Resistance and Co-ordination test did not differ so much between the two groups. On the other hand, in the variable flexibility significant differences were observed (sig.p = 0,0022 << 0,05) between the observed groups, being Group 1 (31,5 ± 6,3) meaningfully less than Group 2 (38,1 ± 4,9), which constitutes a difference of about 21%. Such results present relations of caloric cost compensation between the studied groups, the motivation to the beginners group and flexibility to tne advanced group, justifying the lack of significant distinctions. In this sense the folkloric dance, as a physical activity, appears to be efficient, for significant co-relations are still noticed between the caloric cost levels of the dance with the walking, besides not presenting expressive differences between them.

Marcadores genéticos, antropometria e qualidades físicas básicas nos estágios maturacionais de nadadores paraibanos

The aim of this research was to analyse genetic markers, anthropometry and basic physical qualities in the differret stages of sexual maturation in swimmers in Paraíba. It is characterised as a descriptive cross sectional study. The sample was composed of 119 swimmers (males) that were divided among the stages of sexual maturation, from 7 to 17,9 years of age. They were associated to a local federation, the Confederação Brasileira de Desportes Aquáticos. The tests used were: genetic markers dermatoglyphics; Anthropometry body mass, stature, arm span, fat percentage and somatotype; physical qualities speed tests (25 meters crawl), strength (vertical jump) to inferior limbs, verarm throwing arremesso of a 2kg medicineball to superior limbs and abdominal), resistence (12 minutes to swimming), agility (he multistage 20-meter shuttle run test), flexibility (sit and reach test ) and coodination (stroke index); power of swimming (mean velocity in 25 meters mutiplied by body mass) and the self assessment of the sexual maturation supervised by a pediatric specialist. In the analyses we used the test normality of Shapiro-Wilk, then, we used ANOVA- one way followed by Post-Hoc test of Scheffé. The data showed in dermatogliphics a genetic tendence to velocity (L>W) with a predominance of the meso-ectomorphic somatotype profile; in relation to the physical qualities there was an evolution of the results in every stage due to the antropometric variables, except in the coordination tests. There were no significative differences between the stages. We conclude that swimming in Paraíba is composed of a signicative number of velocists with a mesomorph somatotype profile and low fat percentage, and that made it posssible to us to recomend that the trainings must be individual and according to personal characteristics of each athlete, and that the used variables must be specific for every region of the country. This dissertation presents a relation of multidiciplinar interface and its content has an application in Physical Education and Medicine

Avaliação da qualidade da assistência a pessoas com úlceras venosas atendidas na estratégia saúde da família

A úlcera venosa constitui importante problema de saúde pública, gera repercussão social, econômica e mudanças nos hábitos de vida, dor, sofrimento, acarretando diminuição da qualidade de vida. O estudo objetivou avaliar a assistência prestada às pessoas com úlceras venosas atendidas pela Estratégia Saúde da Família. É um estudo analítico, transversal e quantitativo, realizado com 59 pessoas com úlceras venosas, atendidas em 36 unidades da Estratégia Saúde da Família. O estudo obteve aprovação do projeto de pesquisa pelo Comitê de Ética da Universidade Federal de Alagoas. Para a coleta dos dados utilizou-se instrumento testado, entrevista, exame físico e informações dos prontuários. Os dados foram organizados em planilha do Microsoft Excel 2007, exportados e analisados em software estatístico por meio de estatística descritiva e inferencial, considerando nível de significância estatística de ρ-valor < 0,05. As pessoas com úlcera venosa eram do sexo feminino (71,2%), ≥ 60 anos (67,8%) e estavam em tratamento > 1 ano (69,5%). Possuíam tempo de lesão > 6 meses (64,4%), dor na úlcera/membro (86,4%) e leito com ≤ 30% de granulação/epitelização (78,0%). A qualidade da assistência foi ruim (< 5 aspectos positivos) em 57,6% (ρ=0,000) e os aspectos que mais interferiram foram as seguintes inadequações: profissional que acompanha/realiza curativo (ρ=0,002, coeficiente de contingência (CC) =0,458, razão de chance (RC) =13,9), produtos nos últimos 30 dias (ρ=0,038, cc=0,334, RC=7,3) e acesso a consulta com angiologista (ρ=0,041, cc=0,305, RC=4,1). Os aspectos clínicos que contribuíram para o aumento do tempo de assistência foram: tempo de lesão >6 meses (ρ<0,001), dor (ρ=0,043), recidiva (ρ<0,001); nos aspectos assistenciais: inadequação dos produtos com 83,1% (ρ=0,036). Essas características dificultaram a cicatrização tecidual, prolongando o tempo de tratamento das lesões,que podem ter contribuído para a cronicidade das úlceras

Avaliação da autopercepção estética e qualidade de vida em pessoas vivendo com HIV/AIDS com síndrome lipodistrófica (SLD) em uso de antirretrovirais

Em 1996 com a introdução no Brasil da Highly Active Antiretroviral Therapy (HAART) melhorando a sobrevida e diminuindo o número de óbitos entre os portadores do HIV/Aids, surgem relatos de alterações metabólicas e morfológicas - Síndrome Lipodistrófica (SLD). Portanto, este estudo busca avaliar a partir da autopercepção estética de pessoas que vivem com HIV/AIDS (PVHA) em uso de terapia antirretroviral (TARV) o impacto da SLD na qualidade de vida. Pesquisa exploratória observacional com dados quantitativos e qualitativos, que contou com a multidisciplinaridade, a partir dos critérios de inclusão os voluntários eram captados pelo médico infectologista assistente. Foi realizada com base nos princípios da Resolução 196/96-CNP. A amostra foi composta por 48 PVHA, com idade entre 32 a 66 anos. 89,6% demonstraram interesse em mudar partes do corpo que perceberam enquanto alteradas ou comprometidas pela SLD, dado reforçado quando estes afirmam que se percebem (35,4%) e sentem (35,4%) que as outras pessoas os vêem de forma diferente. Quanto a qualidade de vida o domínio da espiritualidade, religião e crenças pessoais alcançou maior média (14,7) com DP 4,0 neste estudo. A pesquisa permitiu uma publicação internacional (Journal of Public Health and Epidemiology-JPHE) e várias participações com publicação em eventos (nacionais e internacionais). O estudo sugere que a infecção por HIV e a presença da SLD a partir da autopercepção dos sujeitos entrevistados pode afetar a qualidade de vida. E destaca a importância de ações que ressaltem o suporte social como motivador para o autocuidado

Características físicas, somatotipo e desempenho de corredores de 100 e 400 metros no Rio Grande do Norte

Objective: The aim of the study was to investigate physical characteristics and to examine association between somatotype and performance in collegiate runners of 100 m and 400 m. Methods: The sample, male runners (n=39) competing at the regional level in the state of Rio Grande do Norte, Brazil, had height, body mass, skinfolds, limb circumference and skeletal breadths measured. Then, the somatotype was calculated by Health-Carter method. Races (100 m and 400 m) were held to assess athletic performance. Descriptive statistics were calculated for the total sample, as well as for the 100 m and 400 m groups, and established four subgroups, named quartiles. For analysis between groups of runners (100 m x 400 m) was used Student's t test for independent samples. To examine the relationship between the race times and anthropometric variables, was used the Pearson correlation test. The somatotype dispersion distance and somatotype spatial distance were calculated among subgroups. One-way analysis of variance, the Wilcoxon test followed of Tukey post test, and correlation analysis were used with a significance level of p<0.05. Results: Somatotype with mesomorphy and ectomorphy dominance was exhibited by 100 m and 400 m athletes. Endomorphy was low in both groups, especially in 400m runners, who had more elongated body types than 100 m runners. When separately compared by athletic performance quartile, 100 m sprinters of better qualifications (G100-G1) had somatotype with dominant mesomorphy, whereas 400 m runners had somatotype with dominant ectomorphy. A significant correlation (r = -0.55, p=0.008) between calf circumference and 100 m race times was observed showing the importance of muscularity, whereas a significant correlation was found between height and 400 m race times (r = -0.53, p=0.02) showing the importance of linearity. Conclusion: Runners of 100 and 400 may show differences in physical characteristics, depending on the level of athletic performance. Anthropometric periodic evaluations may help in the training process of these athletes. However, more specific assessment parameters should be taken into account, because somatotype by itself has not power to predict whether an individual will succeed in racing speed

Exercício físico, saúde e qualidade de vida em pessoas com HIV/AIDS em Natal/Rio Grande do Norte

A sobrevida das pessoas com AIDS tem aumentado com o uso das terapias com antiretrovirais (TARV), esses, entretanto, possuem efeitos colaterais que interferem no padrão morfofuncional e hematológico, o que pode levar a alterações na qualidade de vida (QV). Este estudo quase-experimental objetivou avaliar parâmetros antropométricos, funcionais, hematológicos e de QV em pessoas com HIV/AIDS submetidas a um programa de exercícios de 16 semanas. Os participantes tinham idade entre 35 e 51 anos (n=15), eram registrados no Núcleo de atendimento do Hospital Giselda Trigueiro em Natal/Rio Grande do Norte e apresentaram CD4350cel/mm3, lipodistrofia e estavam em TARV. Foram avaliados o índice de massa corpórea (IMC), a relação cintura-quadril (RCQ), o percentual de gordura (%G), a força escapular e manual, a contagem de CD4, carga viral e QV, antes e após a intervenção. Essa foi realizada com exercícios de aquecimento e utilizou como base os exercícios resistidos, realizados 3x/semana, com 1h e intensidade de 60 a 75% de 1RM. Observaram-se modificações significativas no %G (p=0,031), força escapular (p=0,007) e preensão manual (p=0,039). Houve aumento no CD4 e a carga viral manteve-se indetectável. Nos domínios da QV, houve mudança significativa no do meio ambiente (p=0,021), espiritualidade, religiosidade e crenças pessoais (p=0,032) e na percepção da qualidade de vida e saúde geral (p=0,005). Os resultados sugerem que os exercícios resistidos para essa população constituem agente terapêutico coadjuvante no controle dos efeitos colaterais advindos da TARV, promovendo modificações na composição corporal, aumento da capacidade funcional e dos níveis de CD4, mantendo estável a carga viral e melhorando a QV. Sugerimos novos estudos com maior tempo de intervenção e com o acompanhamento de equipes multidisciplinares, o que poderá promover melhorias mais significativas na qualidade de vida e efetuar maior controle nas variáveis intervenientes
