Recognition characters and new records of two species of Phylloscyrtini (Orthoptera, Gryllidae, Trigonidiinae) from southern Brazil
Martins, Luciano de P.;Redü, Darlan R.;Oliveira, Gabriel L. de;Zefa, Edison;
Iheringia. Série Zoologia , 2012, DOI: 10.1590/S0073-47212012000100013
Abstract: the phylloscyrtini occurs from eastern united states to argentina and includes 21 valid species. it is a highly neglected group of crickets and little is known about its biology and distribution. cranistus colliurides st?l, 1861 and phylloscyrtus amoenus (burmeister, 1880) were recorded for the state of rio grande do sul, southern brazil, and information on calling song, stridulatory file and recognition characters were provided.

Abstract: This case–control study assessed 20 patients with chronic obstructive pulmonary disease attending a pulmonary rehabilitation program. The group of subjects without COPD (control group) consisted of 20 elderly patients attending a university gym, patients of a private service and a public healthy care. Consumption of oxygen (O2) and carbon dioxide (CO2) was determined by indirect calorimetry and used for calculating the resting energy expenditure and respiratory quotient. Body mass index (BMI) and waist circumference (WC) were also measured. Percentage of body fat (%BF), lean mass (kg) and muscle mass (kg) were determined by bioimpedance. The fat free mass index (FFMI) and muscle mass index (MMI) were then calculated.The COPD group had lower BMI than control (p?=?0.02). However, WC, % BF, FFMI and MM-I did not differ between the groups. The COPD group had greater RQ (p?=?0.01), REE (p?=?0.009) and carbohydrate oxidation (p?=?0.002).Elderly patients with COPD had higher REE, RQ and carbohydrate oxidation than controls.

Abstract: the objective of this work was to evaluate the phenological and physical characteristics, the lipid content and the fatty acid profile of fruit of olive trees from serra da mantiqueira, at minas gerais state, brazil. the cultivars alto d'ouro, arbequina, galega, grappolo 541, grappolo 561, grappolo 575, negroa, penafiel, ropades 392 and santa catalina were evaluated in the 2008/09, 2009/10 and 2010/11 cycles. for fatty acids profile evaluation, crude oil was extracted from lipid-rich cultivars.the flower in granges from july to october, and the harvest from january to march.the earliest cultivar is 'arbequina', and the latest ones are 'galega', 'grappolo 575' and 'santa catalina'. 'grappolo 561' has fruit with the longest transverse diameter, and 'grappolo 541' has fruit with the highest total mass. 'arbequina' and 'grappolo 561' show the highest lipid content.

Abstract: the vegetative propagation of passion fruit can provide to obtain uniform seedlings and orchards, with the use of rootstocks with good characteristics such as tolerance to soil-borne diseases. the objective was to study methods of grafting at different ages of passion fruit plants after emergence. the experiment was conducted at the horticulture sector, of the federal university of lavras (ufla), in mg, on mesh with 50% shading. the experimental design was randomized blocks in a 2x4 factorial design, two methods of grafting (cleft grafting, splice grafting) and four times in budding (15, 25, 35 and 45 days after emergence). it was evaluated: percentage of grafting success, leaf number, plant height and diameter. it is concluded that the grafting of sour passion fruit on the sweet, both in cleft grafting and splice grafting, the best time to perform is 15 days after emergence, showing an index of grafting success of 98% in both methods.

Abstract: Objective: To verify the relation of neck circumference and relativemuscle strength and cardiovascular risk factors in sedentary women.Methods: A cross-sectional study with 60 premenopausal women(33.9±9.1 years; 67.4±13.6kg; 1.57±0.6cm and 27.2±5.3kg/m2). Based on the neck circumference, the sample was divided into two groups: Group Circumference <35cm (n=27) and Group Circumference ≥35cm (n=33) to compare relative muscle strength and cardiovascular risk factors. The correlation between variables was tested by Pearson and Spearman correlations, with a significance level established at p<0.05. Results: The findings revealed that women with neck circumference ≥35cm presented higher values of body mass, waist circumference, body adiposity index, body mass index, systolic blood pressure, blood glucose, glycated hemoglobin and volume of visceral fat when compared with the group with neck circumference <35cm. Additionally, the group with larger neck circumference presented lower values of relative strength. Conclusion: Neck circumference seems to be an important predictive factor of cardiovascular risk and of relative strength loss in middleaged sedentary women.
A Esquerda Contra a Política: organiza es guerrilheiras e renúncia à estratégia no período da luta armada
Darlan Montenegro
Revista Estudos Políticos , 2011,
Abstract: Este artigo aborda a identidade política das organiza es de esquerda que se engajaram na luta armada contra a ditadura civil-militar implantada no país em 1964, com foco na oposi o desses agrupamentos às formas tradicionais de organiza o e estratégia da esquerda ocidental, substituída por uma a o puramente militar. Concluo que a resistência apresentada por essas organiza es aos aspectos teóricos da luta pelo socialismo no Brasil, que consistira num elemento central da identidade das organiza es de esquerda que as precederam, em especial o Partido Comunista Brasileiro e a Organiza o Revolucionária Marxista-Política Operária, permitiria a algumas delas, mais tarde, no fim dos anos 70, constituir um campo comum de preocupa es e identidades com outros segmentos que tomariam parte na constru o do Partido dos Trabalhadores.

Abstract: semi hardwood cutting was colletecd in the medium portion of the 'ascolano 315' olive trees, prepared with 12 cm in length and four leaves, treated or not with 3000 mg l-1 of iba by five seconds. the experiment was conducted in a greenhouse, with a system of intermittent nebulization. the cutting was placed in propagation supports, containing perlite as a substrate. before the plantation of the cutting, organic fertilizers biofertilizante and nippoterra were applied in the proportion: 0, 20, 40 and 60 ml l-1. the products were applied in the experimental portions in a single dose. after 58 days, the percentage of cutting with callus, taken root, taken root and/or with callus, average number of roots and average length of the roots were evaluated. the 40 ml l-1 of biofertilizante gave the best results, with iba.
Lagrange as a Historian of Mechanics  [PDF]
Agamenon R. E. Oliveira
Advances in Historical Studies (AHS) , 2013, DOI: 10.4236/ahs.2013.23016
Abstract: In the first and second parts of his masterpiece, Analytical Mechanics, dedicated to static and dynamics respectively, Lagrange (1736-1813) describes in detail the development of both branches of mechanics from a historical point of view. In this paper this important contribution of Lagrange (Lagrange, 1989) to the history of mechanics is presented and discussed in tribute to the bicentennial year of his death.
History of Two Fundamental Principles of Physics: Least Action and Conservation of Energy  [PDF]
Agamenon R. E. Oliveira
Advances in Historical Studies (AHS) , 2014, DOI: 10.4236/ahs.2014.32008
Abstract: One of the aims most sought after by physics along the years has been to find a principle, the simplest possible, into which all natural phenomena would fit, and which would also allow the calculation of all past occurrences and principally future occurrences. Evidently, this is far from being reached and quite probably does not even exist. Nevertheless, an approximation to this ideal is always possible and the history of physics shows that some results in this direction have been achieved. Thus, the history of the principles of least action and conservation of energy presented in this paper explains the search for this ideal.
Charles-Augustin Coulomb—The Founder of Physiology and Ergonomics  [PDF]
Agamenon R. E. Oliveira
Advances in Historical Studies (AHS) , 2016, DOI: 10.4236/ahs.2016.55017
Abstract: The memoir Sur la force des Hommes was published by Coulomb in 1778. It is an attempt to understand human work mechanically and is the first publication on physiology and ergonomics. The question introduced by Coulomb appears from a pragmatic point of view. He proposed to measure the quantity of action (mechanical work) that a man can expend in a day of work by different ways of applying force. To do this, Coulomb studied the old problem of human mechanical capacity, also studied by Theophilus Desagulliers (1683-1744) and Daniel Bernoulli (1700-1782). In this paper we examine and discuss Coulomb’s above-mentioned publication showing his pioneering approach (Coulomb, 2002).
