Musical auditory stimulation at different intensities and its effects on the geometric indices of heart-rate variability

Introduction: Previous studies have shown that relaxation music increases the heart's parasympathetic modulation as well as reducing its sympathetic activity. However, what is lacking in the literature is information on the acute effects of different intensities of music on cardiac autonomic regulation. We aimed to evaluate the acute effects of baroque and heavy-metal music on cardiac autonomic regulation at different intensities. Method The study was performed in 16 healthy men aged between 18 and 25 years. The main outcomes were the geometric indices of heart-rate variability (HRV) [i.e. triangular index (RRtri); triangular interpolation of RR intervals (TINN) and Poincaré plot: SD1, SD2 and SD1/SD2 ratio]. First, HRV was recorded at rest for 10 min. The volunteers were then exposed to baroque or heavy-metal music for 5 min through an earphone; subjects were exposed to each song at three different sound levels (60–70, 70–80 and 80–90 decibels). After the first song, subjects remained at rest for 5 min before being exposed to the next song. The sequence of songs and sound intensity were randomised for each individual. Results Musical auditory stimulation with baroque music did not influence the geometric indices of HRV. The same was observed with heavy-metal musical auditory stimulation at the three sound-level ranges. Conclusion Musical auditory stimulation at different sound intensities did not influence the geometric indices of HRV in men.

Crescimento, composição mineral e sintomas visuais de deficiência nutricional em ipeca

The objective was to evaluate the effect of the omission of macronutrient and micronutrient boron in dry matter production, the characterization of the symptoms of nutritional deficiencies and mineral composition in plants of ipeca, an experiment was conducted in greenhouse conditions by the technique the missing element and visual diagnosis. A randomized block experimental design with four repetitions and the treatments were: complete and omissions of N, P, K, Ca, Mg, S and B. The analytical results demonstrated that the production of dry matter was affected in all of the treatments with omission of nutrients and that the ipeca plants presented characteristic symptoms of nutritional deficiencies due to the omissions of N, P, K, Ca, Mg, S and B and the concentrations of the macronutrients and of the micronutrient boron in the different parts of the ipeca plant varied when a certain nutrient was omitted in the solution.

Sistema jagunço: localismo e universalismo em Grande sertão : veredas

Under different perspectives of interpretation and analysis, the notions of localism and universalism in the fictional production of Guimarães Rosa have been strongly explored by the criticism, especially in Grande sertão: veredas [The devil to pay in the backlands], in which these two dimensions – overlapped and complementary – become more intricate and profuse. Taking the analytical line of historical, social and political dimensions of the novel for granted – not regarding it as an essay or strict allegory of the country – the present study proposes a new reading of the composition with the interpretation of the articulation of these two dimensions in the forming of the “jagunço system” (ROSA, 1970, p.391), that is a concept created by Guimarães Rosa and which transcends the historical and sociological reality. The articulation of the social, political and cultural elements figure in Guimarães Rosa’s fiction and becomes an issue for wider debates and reflections, so that the particular element of the novel enables a universal survey. Based on diverse critical apprehensions of the novel, this paper aims to investigate the levels of the literary composition in which the local-universal articulation associated with the representation of the jagunço is constructed. In order to do that, the theoretical study is based on three dimensions of studies: a) critical essays about Guimarães Rosa, the totality of his work and specific critical essays about Grande sertão: veredas [The devil to pay in the backlands] and the “jagunço system”, b) theoretical apparatus concerning the history, the politics and the Brazilian culture related to the cangaço; and c) theoretical subsidies for the study of the narrative

Caracterização e origem da composição química da incrustação e simulação de cenários de perda de energia em setor da rede de abastecimento de água da cidade de Rio Claro - SP

The purpose of this work was the inlay’s characterization from the water supply networks of Rio Claro-SP city; as well analyze the influence of network’s aging in the actual system. To do this, some samples of inlays were collected and made chemistry analysis and X-Ray Diffraction Spectrometry. The history of the source water quality was also analyzed, to make possible to known the origins of the inlays. To evaluate the performance of the network, some different scenarios have been simulated, varying the resistance coefficient of the water supply networks of Rio Claro-SP. The characterization results showed that there are basically oxide and hydroxide of iron (magnetite and goethite) and quartz in the inlays, which are materials of high hardness. The hydraulic simulations indicated that the simulated scenarios had a variation of ~2000% in terms of loss of energy

Influência da composição corporal e da síndrome metabólica sobre a relação da aptidão cardiorrespiratória com o estresse inflamatório

Physical activity is associated with lower cardiovascular disease risk factors, being cardiorespiratory fitness a major component of physical activity health related. Body fatness and sarcopenia are related to sedentary lifestyle leading to proinflammatory stress and lower cadiorespiratory capacity. This study aimed correlates C-reactive protein with cardiorespiratory fitness, analyzing the influences of anthropometrics variables and metabolic syndrome (MS) presence. the cross-sectional retrospective study included baseline data of 194 adults (62 male and 132 female), 53,74 ± 8,77 years, clinically and ethically selected for a lifestyle modification program. Total cholesterol (TC) and cholesterol lipoprotein fractions, triglycerides (TG) and glucose was dosed by dry chemistry (Vitros® system, Johnson & Johnson). Blood leukocytes was quantified by automatic cell counter (Coulter ABX®, Horiba). LDL-cholesterol was obtained by Friedwald formula. Serum ultrasensitive C-reactive protein (US-CRP) was accessed by the immunochemoluminescence method (Immulite 2000®, DPC Medlab). Weight, height, body mass index (BMI) and waist circumference (WC) were measured. Muscular mass and fat mass were obtained by bioelectrical impedance analysis (impedancemeter Quantum BIA-101Q®, Clinton Township). Arterial blood pressure was checked by auscultatory method and cardiorespiratory fitness was determined by ergoespirometric test (Balke protocol). The metabolic syndrome was diagnosed according NCEP – ATP III (2001), following recommendations of American Diabetes Association (2004). Pearson’s correlation crude and adjusted for confounders variables with p<0,05. The prevalence of MS was 30.4%.

Caracterização hidroquímica do sistema aquífero Tubarão no município de Americana/SP

The growing interest in the use of groundwater resources is directly related to the economic advantages that the groundwater exploitation offers when compared to surface waters. This happens especially in large urban centers, such as the city of Americana / SP, where the rivers are increasingly contaminated by household and industrial waste. Therefore, this study aimed to characterize the Tubarão Aquifer System, in the city of Americana, to identify and evaluate the spatial distribution of different hydrogeochemical facies as well as understand the rock-fluid interaction through the construction of a conceptual hydrogeochemical model. This study was made based on the recognition of the possible chemical reactions that print the chemical characteristics of groundwater in the area. To do the job, there were two water sampling campaigns of all deep wells used by the City of Americana public water supply. From the results of hydrochemical, classification of water was made by Piper and Stiff diagrams as well as geostatistical data using cluster analysis of principal components. Based on information from the profiles obtained from the survey SIAGAS as well as in geological profiles provided by the city of Americana, we sought to detail the subsurface geology of the Subgroup Itararé in the city of Americana. The results obtained allowed the identification of three hydrochemical types in the study area: Bicarbonated calcium-sodium (1), bicarbonate sodium (2) and sodium chloride (3). The waters have bicarbonate alkaline pH to alkaline and can be considered weakly saline, with electrical conductivity values of around 161 mS / cm. Samples classified as sodium bicarbonate average of 174.99 mS / cm. The pH values ranging from 6.74 to 7.99, averaging 7.52. For the group of waters classified as sodium chloride, conductivity average is 164.32 mS / cm and pH values ranging... (Complete abstract click electronic access below)

Avaliação de atributos do solo e vegetação em sistema agroecológico

A importância da agroecologia se dá no sentido de fornecer e ser, base e estrutura de conhecimentos mesclados, incorporando saberes tradicionais aos saberes técnicos científicos atuais, sem excluir ou rejeitar, mas usando ambos a favor da transição para uma pratica agrícola mais sustentável e coerente com os fluxos e com a complexidade natural de um ecossistema, o que não se percebe nas práticas agrícolas modernas e convencionais. Inúmeros estudos constataram que para uma boa efetividade de sistemas agroecológicos é necessário recuperar e manter o equilíbrio biológico do solo, pois isso influenciará em suas características físicas e químicas. O objetivo desse trabalho foi de caracterizar o solo sob Sistema Agroflorestal (SAF) e uma Pastagem, no município de Rio Claro (SP), para a obtenção de atributos do solo, morfológicos, físicos e químicos e também descrever a diversidade do extrato arbóreo presente na área, incluindo as espécies agrícolas, e levantar o histórico de implantação do sistema, de modo a criar e dar início a formação de um banco de dados científicos para o Grupo de Extensão Gira-Sol. Foram escolhidos dois perfis nas seguintes situações: sistema agroflorestal e uma Pastagem para descrição morfológica do solo. Em cada área foi efetuada a coleta de amostras deformadas e indeformadas e caracterizados os atributos granulometria, analises química, densidade do solo, porosidade do solo e resistência à penetração. Para a descrição morfológica dos perfis foi utilizado os procedimentos descritos por Lemos e Santos (2002), para os atributos químicos e de fertilidade do solo, Camargo et al. (1986) e EMBRAPA (1997), para granulometria, densidade e porosidade do solo e argila dispersa em água. A descrição da vegetação foi feita com auxilio de guias de identificação e por meio de parcelas, onde as espécies foram tabeladas e plotadas em um mapa da área para localização das mesmas, e.
