As Praças Centrais de Presidente Prudente-SP: avaliação do caráter como subsídio para intervenções projetuais

During the process of development and urban sprawl in the city of Presidente Prudente (SP), some factors as the emergence of new centralities, the change in lifestyles and the expansion of equipments and urban infrastructure contributed to the dismantling and little appropriation of the central open space system. In this sense, the work is about the loss of continuity between the central squares of the city - Monsenhor Sarrion Square, July 9 Square, Bandeira Square and Nossa Senhora Aparecida Square - using different methodologies for character evaluation of each square, identifying the inviting and unattractive aspects of their spaces. The relations between these squares and its surroundings are characterized by analyzing interesting visual played on sketches, to complement character evaluation. Among these studies, it is also analyzed two spatial structures related to the squares – Calçadão and Quintino Bocaiuva Street - which have important architectural referring to the city's history and contribute to the central open space system configuration. General considerations obtained through diagnosis provided subsidies for the projectual proposed intervention, which aims to provide appreciation of the character of these public spaces and their articulation, promoting their use and constituting, thus, an important urban-environment set

Proposta de plano de marketing para os serviços de acolhimento a visitantes na igreja de Frei Galvão e Guaratinguetá (SP)

This work contains a preliminary marketing plan for host services on Frei Galvão’s Church in Guaratinguetá, SP, Brazil. It started from the analysis of the current situation and of a study on visitors’ profiles. The development of the marketing plan proposal used the methodology of the 7 P’s of service marketing. The studies brought some relevant results, as they have indicated a lack of restaurants, adequate signalization, restrooms and a good parking lot. The studies have also shown that the host services managers lack data about number of visitors and about the distribution of pills. These results allowed the author to elaborate some strategies and formulate the proposal here presented

As diferentes concepções de corpo ao longo da história e nos dias atuais e a influência da mídia nos modelos de corpo de hoje

Sabe-se até hoje, que falar sobre o corpo não é só tratar de matéria. O corpo tem uma importância bastante grande e interessante dentro do contexto social e filosófico. Sócrates, Platão, Descartes são exemplos de filósofos que tentavam compreender o corpo de alguma forma. Desde a Grécia Antiga, o corpo é encarado como um santuário. Os Jogos Olímpicos representavam essa visão, com toda a beleza de corpos atléticos e vigorosos. Ficava clara a concepção de que um corpo bonito e saudável era sinônimo de beleza e virilidade. Mas nem sempre isso foi assim. Na Idade Média, corpos bonitos eram aqueles que, esteticamente falando, não pareciam tão atraentes assim. Ser gordo nessa época representava saúde. Para as mulheres, ser gorda significava ser uma boa reprodutora e mãe de filhos saudáveis. Além disso, a Igreja exercia forte influência nessa época, chegando até a extinguir os Jogos Olímpicos. Qualquer culto ao corpo era estritamente proibido. Até chegarmos aos dias de hoje, o corpo passou por diversas modificações. O que se vê hoje, são corpos construídos, seja pela mídia ou por cirurgias plásticas. A concepção de corpo da sociedade contemporânea é puramente artificial.

Aplicação dos princípios de radioproteção em medicina nuclear

The Nuclear Medicine is a medical specialty which uses different radioisotopes for diagnostic and therapeutic purposes. The isotopes are radioactive elements which are administered in vivo and present distribution to specific organs or cell types. The knowledge of radioactivity and notions related to ionizing radiation allow to contextualize the radiological protection measures to be taken in Nuclear Medicine. So it is possible to minimize unnecessary exposure to patients, the public, and individuals occupationally exposed and the environmental. For this it is necessary to relate the physical and technological bases apply to this mode with the standards established by regulatory agencies, including the CNEN (National Nuclear Energy Commission) and ANVISA (National Agency for Sanitary Vigilance). In this scenario, it is important that the theoretical endorse the activities which are periodically audited for verification of compliance with the standards that aim to radioprotection. One role of the Medical Physicist in these services is, therefore, act as Radiation Protection Supervisor exerting numerous activities and ensuring compliance with these standards. In this context the stage in the area of Nuclear Medicine was developed in many customers of the enterprise Rad Dimenstein & Associados LTDA, among them the hospitals Israelita Albert Einstein (HIAE), Nossa Senhora de Lourdes (HNSL), Santa Paula (HSP), Cruz Azul (CRAZ), Grupo Fleury, among other clinics. Following the routine and then carrying out various activities pertaining to the Medical Physicist in the area, it was noted that the measures and actions are extremely effective and fundamental in terms of radiological protection

Cryptotermes brevis (Isoptera, Kalotermitidae): biologia e polimorfismo de imaturos

Cryptotermes brevis (Walker, 1853) é um cupim de madeira seca exótico no Brasil, pertencente a família Kalotermitidae e que possui uma distribuição geográfica bastante ampla, sendo encontrada somente em ambientes sinantrópicos. Esta espécie de cupim de madeira seca vive dentro de pedaços de madeira onde escava suas galerias por meio da alimentação. Estes insetos se alimentam do próprio ninho onde vivem e sua infestação é percebida pela formação de grânulos fecais sólidos que são expulsos de peças de madeira infestadas. Dessa forma, C. brevis causa grandes danos econômicos em áreas urbanas, infestando peças de mobiliários manufaturados pelo homem e estruturas de madeira como batentes, forros, rodapés, etc. Em uma colônia de cupins de madeira seca existem castas morfofisiologicamente diferentes, as quais realizam tarefas distintas. Entre elas estão as castas ápteras (soldados e falsos operários), e os reprodutores (rei e rainha). A maioria das castas de cupins são cegas e exibem comportamentos característicos que são utilizados na comunicação entre eles, como por exemplo trofalaxia estomodeal e proctodeal, “grooming”, antenação, “butting”, etc. Devido ao reduzido conhecimento da biologia dessa importante praga urbana, o presente trabalho objetivou elucidar as aspectos da biologia e do polimorfismo de imaturos nesta espécie de cupim. Para entender o polimorfismo de larvas e ninfas foi realizado um estudo biométrico em que mensurou-se a largura da cabeça e do pronoto e o comprimento do broto alar e da tíbia. Os resultados obtidos mostraram três ínstares larvais e quatro ínstares ninfas. Adicionalmente, foram iniciadas colônias que foram abrigadas em diferentes volumes (300 cm3 e 150 cm3) e tipos de madeira. Estas colônias incipientes de laboratório foram abertas após seis meses e mostraram uma média de 5 indivíduos por colônia... (Resumo completo, clicar acesso eletrônico abaixo)

RPG e mídia: uma análise do caso Ouro Preto

This paper is intended to perform an analysis of the news published by the Website Ouropreto.com.br and the portals and Uai e Terra in news about the murder of the student Aline Silveira Soares and about its judgment. According with the news, the student's body was found in the cemetery of the church Nossa Senhora das Mercês e Misericórdia on 14th October 2001 in the city of Ouro Preto in Minas Gerais. The police and the media reverberated the hypothesis that Aline would had been killed during a Satanic ritual related to the RPG game(Role Playing Game) which is a game where players assume characters within a story. Our proposal is to analyze the coverage of vehicles of different ranges (local, regional and national) and evaluate how the case was shown focusing on its supposed relationship with the RPG game

Estudo do comportamento em fadiga de um tubo de aço API 5CT soldado por resistência elétrica

The oil extraction in deep waters sparked new areas of knowledge, the creation of engineering courses dedicated just to these processes and a wide field of analysisvoiding multiple impacts in case of faults, mainly the economic and environmental. This paper aims to show on the effects and causes of fatigue failure in steel tubes used for oil and gastransportation (linepipe), mainly caused by vortex induced vibrations, or VIV. To make this, through laboratory tests, it found trough the curve Stress versus Number of Cycles, and thus estimating that with a stress value of 350 MPa or less, the fatigue life cycle of the API 5CT T95 (1% Cr) pipe is estimated infinite. It could conclude that the analyzed material has good fatigue failure resistance for offshore use, taking into account only the influence of VIV's, since there are no stress concentrators

Bioconversion of Cellulose to Hydrogen by dark fermentation

Hydrogen is known as a clean energy resource. The biological production of hydrogen has been attracting attention as an environmentally friendly processs that does not consume fossil fuels. Cellulosic plant and waste materials are potential resources for fermentative hydrogen production. Cellulose is a linear biopolymer of glucose molecules, connected by β-1,4-glycosidic bonds. Enzymatic hydrolysis of cellulose requires the presence of cellulase. The present study aimed to investigate the efficiency of acid pretreatment on ruminal fluid in order to enrich H2 producing bacteria consortia to enhance biohydrogen rate and substrate removal efficiency. In this study, fermentative hydrogen producers were enriched on cellulose (2g/L) in a modificated Del Nery medium (DNM) at 37ºC and initial pH 7.0 using rumen fluid (10% v/v) as inoculum. To increase the hydrogen production it was added cellulose (10mL) to the medium. The gas products (mainly H2 and CO2) was analyzed by gas chromatography (Shimadzu GC 2010) using a thermal conductivity detector. The volatile fatty acids and ethanol were also detected by GC using a flame ionization detector. Cellulose degradation was quantified by using the phenolsulfuric acid method. Analysis showed that the biogas produced from the anaerobic fermentation contained only hydrogen and carbon dioxide, without detectable methane after acid pretreatment test. On DNM the hydrogen production started with 4 h (5,3 x 105 mmol H2/L) of incubation, and the maximum H2 concentration was observed with 34 h (7,1 x 106 mmol H2/L) of incubation. During the process, it was observed a predominance of acetic acid and butyric acid as well as a low production of acetone, ethanol and nbutanol in all experimental phases. Butyrate accounted for more than 77% of total. As a result of the accumulation of volatile fatty acids (VFAs), the pH value in anaerobic digestion system was reduced to 4,0. On microscopy analyses there were observed rods with endospores. The batch anaerobic fermentation assays performed on anaerobic mixed inoculum from rumen fluid demonstrated the feasibility of H2 generation utilizing cellulose as substrate. Based on the results, it can be concluded that the acid treatment was efficient to inhibit the methanogenic archaea cells present in rumen fluid. The rumen fluid cells present a potential route in converting renewable biomass such as cellulose into hydrogen energy.

Biological Hydrogen production from environmental sample in tropical countries

The hydrogen gas is regarded as clean and renewable energy source, since it generates only water during combustion when used as fuel. It shows 2.75 times more energy content than any hydrocarbon and it can be converted into electrical, mechanical energy or heat. Inoculum sources have been successfully tested for hydrogen biological production in temperate climate countries as sludge treatment plants sewage, sludge treatment plant wastewater, landfill sample, among others. However, hydrogen biologic production with inoculum from environmental samples such as sediment reservoirs, especially in tropical countries like Brazil, is rarely investigated. Reservoirs and fresh water lake sediment may contain conditions for the survival of a wide variety of microorganisms which use different carbon sources mainly glucose and xylose, in the fermentation. Glucose is an easily biodegradable, present in most of the industrial effluents and can be obtained abundantly from agricultural wastes. A wide variety of wastewater resulting from agriculture, industry and pulp and paper processed from wood may contain xylose in its constitution. Such effluent contains glucose and xylose concentrations of about 2 g/L. In this sense, this work verified hydrogen biological production in anaerobic batch reactor (1L), at 37 ° C, initial pH 5.5, headspace with N2 (100%), Del Nery medium, vitamins and peptone (1 g/L), fed separately with glucose (2g/L) and xylose (2 g/L). The inoculum was taken from environmental sample (sediment reservoir Itupararanga - Ibiúna - SP-Brazil). It was previously purified in serial dilutions at H2 generation (10-5, 10-7, 10-10), and heat treated (90º C - 10 min) later to inhibited the H2 consumers. The maximum H2 generations obtained in both tests were observed at 552 h, as described below. At the reactors fed with glucose and xylose were observed, respectively, 9.1 and 8.6 mmol H2/L, biomass growth (0.2 and 0.2 nm); consumption of sugar concentrations 53.6% (1.1 glucose g/L) and 90.5% (1.8 xylose g/L); acetic acid generation (124.7 mg/L and 82.7 mg/L), butyric acid (134.0 mg/L and 230.4 mg/L) and there wasn’t methane generation in the reactors. Microscopic analysis of biomass in anaerobic reactors showed the predominance of Gram positive rods and rods with endospores, whose morphology is characteristic of H2-generating bacteria, in both tests. These species were selected from the natural environment. In DGGE analysis performed difference were observed between populations from inoculum and in tests. This analysis confirmed that some species of bacteria were selected which remained under the conditions imposed on the experiment. The efficiency of the pre-treatment of inoculum and the imposition of pH 5.5 inhibited methane-producing microorganisms and the consumers of H2. Therefore, the experimental conditions imposed allowed the attainment of bacterial consortium of producer H2 taken from an environmental sample with concentration of xylose and glucose similar to the ones of the industrial effluents.
