    Full Text Available A cross-sectional study was carried out to determine the prevalence, severity and impact of toothache among schoolchildren associated with socio-demographic variables (gender, degree of maternal schooling, economic group, and oral health status. Six hundred and one 8- and 9-year-old children were randomly selected from schools in Belo Horizonte, MG, Brazil. After formal authorization was obtained from their parents, the children were interviewed and clinically examined by a single examiner. The Chi squared test was applied and the odds ratio obtained. The prevalence of toothache was 45.9% (276/601, of which 15.6% (94/601 had occurred during the previous month. Among the children who had experienced pain, 39.4% (109/276 classified its severity as intense or very intense. Nearly 35% (96/276 were awoken by the pain, and 63.8% (176/276 were unable to carry out daily tasks as a result. The prevalence of pain was greater among children from less privileged economic groups, in which the mothers' level of schooling was lower (0-7 years of formal study and who showed poorer conditions of oral health, determined by the presence of dental and periodontal pathology (p<0.05. Gender did not influence either the experience of toothache or its severity and impact. The prevalence of toothache found in the age group between 8 and 9 years is very high and associated to social determinants and poorer conditions of oral health.

  4. Geologic evolution of the SE.23 Sheet - Belo Horizonte, MG, Brazil

    International Nuclear Information System (INIS)

    The aim of this paper is to present a synthesis of the geologic evolution in the Belo Horizonte Sheet comprising an area about 281.210 Km2. Rb-Sr and K-Ar isotope dating methods are used for age estimation of geologic deposits. The geologic evolution of the cratonic area is reflected by a stable central nucleus surrounded by marginal orogenic belts. In the central area were recognized greenstone belts structures involved by granite terrains and bordered by a granulitic region. The framework of the Sao Francisco Craton involves events of metamorphism, granitogenesis, sedimentary, volcanism and plutonism developed in the Early to Late Proterozoic. The stratigraphic column is complemented by Late Jurassic-Early Cretaceous continental deposits belonging to Parana-Basin. (M.V.M.)

Methods: For descriptive epidemiological study, the data were obtained from the municipal National Health Surveillance System, after obtaining approval from the Research Ethics Committee at the City Health Department. Incidence coefficient, average rates and stratified data analysis with significance level of p ≤ 0.05 were calculated. Results: About 7.590 new tuberculosis cases were reported between 2002 and 2008. There was a slight reduction in the number of cases throughout the historical trend, with an average annual incidence rate of 46/100,000 inhabitants. The study also showed a male gender ratio of 1.84:1, a higher incidence coefficient in the age group between 40 and 59 years old (73/100,000 and a higher incidence of tuberculosis among people who only had primary education level. Pulmonary tuberculosis was the most prevalent form in every year of the study (p < 0,001. Among the cases reported with associated diseases, alcoholism was registered in 47.9% and AIDS in 34.5%. Between 2002 and 2008, there was an increasing trend of cases treated under Directly Observed Treatment, accounting for 29.5% in total. Cure percentage rate was below the expected result (67.3% and non-adherence to treatment showed a high total percentage (17.9%. Conclusion: The results indicated that tuberculosis control actions need to be intensified with investments on professional training, systemic audits of the information system, improved integration between AIDS/tuberculosis programs and raising awareness of the disease with the goal of mobilizing the society.

    Full Text Available Spontaneous subarachnoid hemorrhage accounts for 5 to 10 % of all strokes, with a worldwide incidence of 10.5 / 100000 person/year, varying in individual reports from 1.1 to 96 /100000 person/year. Angiographic and autopsy studies suggest that between 0.5% and 5% of the population have intracranial aneurysms. Approximately 30000 people suffer aneurysmal subarachnoid hemorrhage in the United States each year, and 60% die or are left permanently disabled. We report our experience in the surgical treatment of intracranial aneurysms in a six year period, in Belo Horizonte, Minas Gerais, Brazil. We reviewed the hospital files, surgical and out-patient notes of all patients operated on for the treatment of intracranial aneurysms from January 1997 to January 2003. Four hundred and seventy-seven patients were submitted to 525 craniotomies for treatment of 630 intracranial aneurysms. The majority of patients were female (72.1% in the fourth or fifth decade of life. Anterior circulation aneurysms were more common (94.4%. The most common location for the aneurysm was the middle cerebral artery bifurcation. The patients were followed by a period from 1 month to 5 years. The outcome was measured by the Glasgow Outcome Scale (GOS. At discharge, 62.1% of the patients were classified as GOS 5, 13.9% as GOS 4, 8.7% as GOS 3, 1.7% as GOS 2 and 14.8% as GOS 1.A hemorragia subaracnóidea espontânea é responsável por cerca de 5 a 10% de todos os acidentes vasculares cerebrais, com uma incidência mundial de 10,5 / 100000 pessoas/ano, variando em estudos individuais de 1,1 a 96 / 100000 pessoas / ano, de acordo com diferenças étnicas e geográficas.

Os dados foram analisados à luz da técnica de análise de discurso. Percebeu-se que a maioria dos gestores adota comportamentos policrônicos e acelerados. Eles têm uma preocupação marcante com o cumprimento das metas, denotando elevado senso de pontualidade. Não se observou uma preferência distinta dos entrevistados em termos de profundidade temporal. A partir da análise dos três processos de arrastamento delineados pelos autores - sincronia, liderança, condução -, foi possível observar uma nítida relação entre tempo e poder, denotando a face ambígua, contraditória e fragmentada da gerência.

This fact is important, principally, when it concerns public health, because this is considered the breathable fraction of particles that can penetrate deeply into the lungs and cause damage to the alveoli. Once in the atmosphere the concentrations of trace metals, in general, show very low levels, thus the determination of the elementary composition of those particles requires the use of appropriate analytical techniques such as Particle Induced X-Ray Emission (PIXE), Neutron Activation Analysis (NAA) and X-Rays Fluorescence spectrometry (XRF), among others. The main objective of this study was the identification of the generating sources of gross (PM{sub 10}) and fine (PM{sub 2.5}) particles present in the atmospheric aerosols of the metropolitan region of Belo Horizonte. Neutron Activation Analyses by k{sub 0}-method (k0NAA) combined with energy dispersed by X-ray fluorescence was used to measurement of the concentration of trace elements present in each sample. High levels of particulate concentrations, especially PM{sub 2.5}, were measured during the sampling period. In general, the air quality varied from Reasonable to Inadequate. The receptor model used to assist in the identification of the main emission sources was the Principal Components Analysis. The results showed that the main elements presents in particulate inhalable matter (PM{sub 2.5} and PM{sub 10}) were Ag, Al, As, Au, Ba, Br, Ca, Cl, Cr, Cu, Fe, K, Mn, Na, S, Sb, Sc, Si, Ti, W and Zn. The results for multi-variable analyses shown clearly four pollutant sources, these being: vehicular emissions; resuspended soil/asphalt powder; secondary aerosols associated with emission of SO{sub 2} and industrial emissions associated with fossil oil burning.

    The increasing expansion of compounding pharmacy associated with several reports on variances in the quality of compounded drugs demonstrates the need for verification of quality, safety and efficacy of these products. In this work, physical and chemical analyzes were performed to evaluate the quality of some capsules manipulated enalapril and simvastatin, acquired in five pharmacies in Belo Horizonte /Brazil. Among the analyzes are pharmacopoeial tests for appearance, identification, determination of weight, content, related compounds and uniformity of dosage units, and was also performed neutron activation analysis for the determination of inorganic impurities in drugs sampled. The results showed that 60% of the samples were unsatisfactory for pharmacopoeial tests. The contents of the capsules sampled for individual testing unit dose uniformity between 0% and 136.2%. This test is important in evaluating the quality, which influences the safety and efficacy of drug treatment, since it allows you to check if the product contains the proper dosage and necessary for successful pharmacotherapy. On the other hand, underdosing can lead to reduced or absent desired therapeutic response, and overdoses can provide an undesirable effects and even toxic. The concentration of inorganic impurities was considered to be relatively small. However, no specific limits for some chemical elements in medicine hamper a better thread. In addition, further studies must be performed to assess chronic exposure to low concentrations of inorganic impurities, since drugs can be continuously used, and other sources of exposure must also be considered in order to evaluate the risk. The problems related to the quality and safety of compounded drugs are still reality in the country and reveal a serious public health problem, especially regarding the lack of uniformity between the unit doses of medications. It is suggested that the competent authorities to sanitary products, propose changes in

    The Engenho Nogueira Hydrological Project, PROHBEN, was idealized with the goal to important an Experimental Hydrogeological Basin within its limits, in order to permit the development of hydrogeological studies and techniques, mainly in modeling the flux and transport of contaminants in saturated and unsatured porous media. The PROHBEN is located in Belo Horizonte city, Minas Gerais State, performing a 5 km{sup 2} area. The lithologies that compound the study area were divided in four geological units. The Unit A is mainly composed by the unweathered gneiss of the Archean Belo Horizonte Regional Complex, and form the bedrock of the local aquifer. The Unit B is constituted by weathered products of the Unit A rocks. Alluvial and colluvial deposits compound the C and D Units, respectively. The local porous, water-table Engenho Nogueira Aquifer reaches the thickness of 40 meters and is mainly formed by the sand-clays lithologies of the B and D geological Units. First results of seven pumping tests performed in local wells are now been analysing, and they are showing a 10{sup -4} cm/s value for the aquifer hydraulic conductivity. Three master degree studies are being performed in the PROHBEN area and one hope is that more researchers come to use this experimental field site. (author) 6 refs.

    Full Text Available Introduction: Acute infectious diarrhea is still regarded as a public health problem associated with a wide range of etiologic agents, from which Salmonella enterica is particularly worth mentioning inasmuch as it is a major cause of inflammatory diarrhea in both developed and developing countries. Objective: To assess the distribution of S. enterica among children with acute diarrhea in Belo Horizonte and to characterize bacterium isolates. Material and methods: The study group comprised a total of 157 children from low socioeconomic background. Stool samples were collected for leukocyte analysis and Salmonella bacterial culture. The isolates were serotyped and evaluated as to antimicrobial susceptibility profile, extended-spectrum β-lactamases (ESBL production, and presence of virulence markers (invA, iroB, and spvC. RESULTS: A total of 5/3.2% children were infected by S. enterica, 3/60% by S. enterica Typhimurium, 1/20% by S. enterica Enteritidis and 1/20% S. enterica subsp. enterica serotype 8.20:z4,z23:-. Fecal leucocytes were detected in two out of five fecal specimens positive for S. enterica. Isolates from three children were resistant to nalidixic acid, nalidixic acid + chloramphenicol, and nalidixic acid + chloramphenicol + ampicillin. ESBL production was not detected. All samples presented invA and iroB genes. spvC marker was observed in isolates from two children infected by S. Typhimurium and S. Enteritidis. Conclusion: The results demonstrate that S. enterica infection is uncommon among children from our region. Furthermore, they indicate the need for periodic monitoring of bacterial antimicrobial susceptibility profile in order to establish suitable antimicrobial therapy when required.INTRODUÇÃO: A diarreia infecciosa aguda é considerada um problema de saúde pública associado a uma ampla gama de agentes etiológicos, entre os quais destaca-se Salmonella enterica, causa importante de diarreia inflamatória em pa

Investiga-se o acesso a estas consultas entre mulheres residentes em Belo Horizonte, com idades de 18 a 59 anos, bem como suas percepções sobre este acesso. O estudo foi desenvolvido em duas etapas: uma análise quantitativa por meio do método Grade of Membership (GoM, buscando delinear perfis de mulheres de 18 a 59 anos, que realizaram e não realizaram a consulta ginecológica nos 12 meses anteriores à pesquisa; e uma análise qualitativa, com base em 33 entrevistas semi-estruturadas, buscando captar a percepção que mulheres com características similares aos perfis extremos delineados na primeira etapa tinham sobre a consulta ginecológica. Os dados quantitativos são oriundos da pesquisa SRSR (Saúde Reprodutiva, Sexualidade e Raça/cor, realizada pelo Cedeplar em 2002. Já os dados qualitativos são provenientes da pesquisa "Aspectos quantitativos e qualitativos acerca do acesso à contracepção e ao diagnóstico e tratamento do câncer de colo uterino: uma proposta de análise para o município de Belo Horizonte, MG", ocorrida entre 2005 e 2006. Os resultados quantitativos sugerem que a realização de uma consulta ginecológica está muito relacionada às características socioeconômicas e demográficas das entrevistadas. Nota-se, também, que as mulheres com maior probabilidade de terem ido ao ginecologista, nos últimos 12 meses, são aquelas que tiveram um acompanhamento ginecológico regular e que costumavam procurar este profissional por meio de consultas particulares ou planos de saúde. Os resultados qualitativos reafirmam o desconforto das mulheres diante da consulta, sendo maior entre aquelas com menos escolaridade. Notou-se também que a primeira consulta ginecológica ocorreu em momentos muito diferentes para as mulheres de alta e de baixa escolaridade - para as primeiras está geralmente relacionada ao início da vida sexual e ao uso de contracepção, enquanto para

O objetivo é analisar os modos de vida juvenis apreendendo os significados e sentidos da saúde em seu cotidiano. Trata-se de uma investigação qualitativa, fundamentada na dialética, com base na sociologia da vida cotidiana. Desenvolvida num bairro popular do município de Belo Horizonte, foi estruturada em fase exploratória e interpretativa, tendo como sujeitos dezenove jovens. Por meio da análise hermenêutica e dialética, a tese foi confirmada. As ações de cuidado presentes no cotidiano dos jovens levam em conta os recursos e os aspectos constitutivos da condição juvenil, ainda pouco contemplada nas proposições da área da saúde. No cotidiano dos jovens, tem-se a expressividade dos modos de vida e da condição juvenil na qual a saúde se revela pelo bem-estar e pelas condições básicas para o trilhar da vida. A concepção de saúde prevalente centra-se nos comportamentos e na corporeidade. Para a promoção da saúde juvenil é necessário partir dos modos de vida juvenis e interagir com eles no cotidiano. As ações de cuidado com a saúde têm um espaço de (invisibilidade na vida dos jovens e interagem com suas prioridades na vivência da condição juvenil. Revelou-se a importância da proposição de ações cuidadoras nos microespaços e no território em que se expressa essa condição.

Nesse cenário, a violência sofrida pela mulher vem-se tornando mais visível à sociedade a partir das denúncias de agressões sofridas. Este estudo se propõe a descrever dados referentes às lesões corporais na região peribucal em mulheres que sofreram agressão. Foram analisados os registros e laudos encaminhados ao setor de Odontologia do IML de Belo Horizonte, referentes ao período de janeiro de 2001 a junho de 2002. Neste período, foram atendidas 108 mulheres. A faixa etária predominante foi a de 20 a 39 anos (70,4%. A maioria dessas mulheres declarou: ser solteira (63,0% e ser natural do interior do Estado (48,1%. Quanto à ocupação encontrou-se: 24% que realizam trabalhos domésticos, 21% que são donas-de-casa e 14% que trabalham no comércio. A proporção de mulheres procedentes das Delegacias Seccionais foi maior do que aquelas encaminhadas pelas Delegacias de Mulheres. A lesão de tecido mole mais freqüente foi a laceração; a de tecidos duros e da polpa foram as fraturas de esmalte e dentina sem complicações; a de tecidos periodontais foi a concussão; e foram observadas duas lesões em tecidos ósseos. O estudo permitiu constatar a necessidade de uma coleta de dados mais cuidadosa nos exames periciais, de modo a disponibilizar informação mais detalhada da violência contra as mulheres; além disso, revelou que as lesões buco-dentais são freqüentes e representam uma grande demanda para os serviços odontológicos de saúde pública que prestam esse atendimento.Violence has been a growing problem in the past years in Brazil.

    Human beings are exposed to ionizing radiation from many natural sources. Radon and its progeny have been recognized as the most important contributors to the natural radioactivity dose, accounting for about half of all human exposure to ionizing radiation. Radon ({sup 222}Rn) is a alpha-radioactive noble gas derived from the natural series of uranium (2{sup 38}U), which occurs in a wide concentration range in all geological materials, especially, in rocks, soils and waters. By diffusion and convection, radon migrates from the rocks and soils to atmosphere and through fissures, pipes and holes it may enter the dwellings and other buildings. Another important radon source in dwellings is its emanation from the construction material. The radon progeny concentration in dwellings has been receiving considerable global attention due to its potential effect in causing lung cancer if it deposited in upper respiratory tract when inhaled. This paper presents radon concentration distribution in dwellings in Metropolitan Region of Belo Horizonte - RMBH. The effective dose estimate is also presented for the RMBH inhabitants. The geological settings of the area are Archean rocks of Granitic Gnaissic Complex and of metasediments sequences of the great Precambrian unit of the Iron Quadrangle of Minas Gerais, Brazil. Radon concentration measurements were carried out with continuous detector AlphaGUARD PQ200PRO (Genitron), in passive mode and with passive detectors E-PERM{sup R} Eletret Ion Chamber-EIC. The radon progeny concentration was carried out with a solid state alpha spectroscope, the DOSEman PRO (Sarad). It was found an indoor radon concentration varying in a large range from 18.5 to 2671.4 Bq/m{sup -3}, with an average value of 148.0 Bqm{sup -3} and geometric mean equal to 128.2 Bqm{sup -3}. The variable results are due mainly to region geological factors and building material composition of dwellings. The equilibrium factor between radon and its progeny were determined

    Radon, the natural radioactive gas is produced by the radioactive decay of uranium and thorium which are ubiquitous, specially in rock and soil. By diffusion and convection. Radon migrate from the rocks and to the groundwater and to the soil and from them the radon migrate through fissures, pipes and hales to the surface. Measurements were carried out in the Metropolitan Region of Belo Horizonte, whose greatest part of the in habitants occupies the great pre cambrian unit of the Iron Quadrangle of Minas Gerais denominated 'Granitic Gneissic Complex', composed of Archean rocks of age between 3,2 Ga and 2,6 Ga. The part in which occurs in the municipal area of Belo Horizonte was denominated as Complexo Belo Horizonte, whose most characteristics rocks named Gneiss Belo Horizonte. The soil gas radon concentrations were determined by using a samples and a continuos flow through ionization chamber detector AlphaGUARD PQ2000PRO - Genitron Instruments GmbH in a Instrumental Neutron Activation Analysis). Most results of radon concentration soil gas were in the range 10 kBq/m{sup 3} to 50 kBq/m{sup 3}. This values, according to the established Swedish Criteria are normal risk values. For soils classified as normal risk require 'radon protective construction', but the necessity of mitigation actions will depend on other factors, for example the soil permeability and rock type.

The diagnosis was based upon clinical picture or actual snake identification. Fifty six percent of victims were bitten by the snakes of genus Bothrops, 32.0% by Crotalus, 1.0% by Lachesis and 10.0% undetermined. During the study period, stable number of cases and marked seasonal variation were noted. In comparing cases of snakebite and controls, those from a rural area or who were involved in agricultural labor activity were identified as a high risk group, with an odds ratio (OR of 14.7 and 6.7, respectively, in favor of being bitten. Upon treatment, snakebite patients were 13.5 times more likely to have had early anaphylactic reactions than their controls, with a higher association in the age group ³ 20 years (OR = 30.3. Increased risks were also detected for pyrexia (OR = 11.7, with a marked association in the group under 19 years old (OR = 16.6. Severe cases of snakebite are an important treatable cause of morbidity in Brazil but therapy may be potentially life threatening. The higher case-fatality ratio encountered, compared to national statistics may be due the representativeness of the more severe cases who sought hospitalization.

    International Nuclear Information System (INIS)

    The Metropolitan Region of Belo Horizonte presents many industrial activities related to several industries, mainly mining activities, besides the high population concentration, which also contributes to several industrial typologies due to the existence of qualified work and to the vicinity of a future consumer market. This concentration of the population also implies in a great number of vehicles and, consequently, in big traffic jams. The particulate material is one of the pollutants which cause higher environmental risk and it is a mixture of solid and liquid particles in the air which form aerosols. These aerosols, which contain organic and inorganic substances, vary of size, form, composition and origin. In order to characterize the quality of the airborne particulate matter and identify the pollutant sources, a research is being developing in the Metropolitan Region of Belo Horizonte. This paper is focused on presenting the methodology of sampling, determination of concentration of particulates, elemental concentration analysis by k0-Neutron Activation method and meteorological analysis, related to two sampling points, one at CDTN/CNEN and other at UFMG.

    Full Text Available A study on the phlebotomine sand fly fauna in Belo Horizonte city, state of Minas Gerais, Brazil, was carried out. From April 2001 to March 2003, monthly systematic collections were performed in three houses from each of the nine regions of the city, using CDC light traps for four consecutive days. The traps were set into the houses and in peridomestic areas totaling 54 traps. A number of 3871 sand fly specimens of the genera Lutzomyia and Brumptomyia were collected. Sixty eight percent of the specimens were L. longipalpis and 16% L. whitmani, insect vectors of visceral and American cutaneous leishmaniasis, respectively. Environmental factors such as temperature, humidity, and frequency of precipitation suggest that the number of insects increases after rainy periods. During the same period mentioned above, seasonal captures were carried out in parks and green areas of Belo Horizonte, using Shannon trap. A total of 579 phlebotomine sand flies were collected from which 398 (68.7% were females with the predominance of L. whitmani and L. monticola. Those specimens were used for natural infection examination, by polymerase chain reaction. No Leishmania DNA was present in any of the specimens tested.

Foram utilizadas as bases de dados da Polícia Militar e do Serviço de Atendimento Móvel de Urgência (SAMU. Para identificar as interseções críticas foram calculadas as taxas de severidade dos acidentes. Utilizou-se duas técnicas de estatística espacial para analisar os aglomerados de acidentes: análise de kernel e estatística Scan (modelo de Poisson contínuo. Os aglomerados de risco de acidentes foram detectados na Região Central e nos corredores de tráfego. O risco de acidentes, inclusive fatais, foi maior em segmentos que nas interseções. As interseções críticas são rotas de acesso para as regiões da Grande Belo Horizonte. As taxas de mortalidade e de acidentes apresentaram duas tendências distintas. Além disso, a maioria dos óbitos ocorreu à noite. Justifica-se a importância da melhoria das rotas para os motociclistas e do transporte público.

  13. Radioactivity of building materials and the gamma radiation in dwellings in Belo Horizonte, Brazil

    International Nuclear Information System (INIS)

    Building materials are known to contain naturally occurring radioactive materials (NORM). The radionuclides which contribute to the external exposure are 40 K and the gamma emitters members of the natural decay series 238U, 235U and 232Th. Samples of the statistically more important buildings materials utilized in the Metropolitan area of Belo Horizonte were collected and their uranium and thorium concentration were determined by INAA. The gamma emitters were spectrometrically determined by solid state detectors HPGe in a very low background laboratory. A model room was used for calculating the indoor mean exposure in dwellings. Due to the lack of regulation for radioactivity in buildings in Brazil, the measured activity concentration was compared with those of other countries. A discussion about the utilization of building material containing TENORM industrial residues is presented. (author)

    Even after the publication of Law 8213 in 1991, which established quotas for employing disabled persons, their inclusion in the workplace still presents a challenge for Brazilian society. In order to understand the main barriers that hamper this process a qualitative research study was conducted in the municipality of Belo Horizon-te. This study included interviews with important actors involved in the process of inclusion; and focus groups including disabled persons and members of their families. The main barriers encountered were: preconceived ideas and discrimination; family relationships; the Continuous Cash Benefit (BPC) program; the low level of qualifi-cation among disabled person; lack of access; and the unpreparedness of companies. It was concluded that drafting laws is not sufficient to guarantee inclusion in the labor market and that governments should implement public policies to assist in this process.

    In this work soil samples, iron ore and airborne atmospheric particulate matter (PM) in the Metropolitan Region of Belo Horizonte (MRBH), State of Minas Gerais, Brazil, are investigated with the aim of identifying if the sources of the particulate matter are of natural origin, such as, resuspension of particles from soil, or due to anthropogenic origins from mining and processing of iron ore. Samples were characterized by powder X-ray diffraction, X-ray fluorescence and {sup 57}Fe-Moessbauer spectroscopy. The results showed that soil samples studied are rich in quartz and have low contents of iron mainly iron oxide with low crystallinity. The samples of iron ore and PM have high concentration of iron, predominantly well crystallized hematite. {sup 57}Fe-Moessbauer spectroscopy confirmed the presence of similar iron oxides in samples of PM and in the samples of iron ore, indicating the anthropogenic origin in the material present in atmosphere of the study area.

    The Belo Horizonte Observatory for Urban Health (OSUBH), housed in an academic setting, was founded in 2002 as part of a broader agenda to strengthen local and national health systems. Its mission is to build the capacity of the workforce in research on population health and to conduct studies on urban issues that can guide the planning of activities aimed at improving the health of populations, especially in heavily urbanized areas, associated with intra-urban inequalities. It focuses on the acquisition of advanced knowledge on urban health (metric) through scientific research, to contribute to public policies that may interfere with health, both at individual and community levels.

MÉTODOS: O número de óbitos ocorridos na região metropolitana de Belo Horizonte, MG, foi obtido do Sistema de Informações em Mortalidade do Ministério da Saúde (SIM-MS e o número de nascidos vivos foi estimado a partir das estatísticas do registro civil da Fundação Instituto Brasileiro de Geografia e Estatística (IBGE, com correção dos registros atrasados de nascimentos. Utilizou-se modelo de regressão linear simples para estimar a tendência temporal das taxas de mortalidade infantil e seus componentes. A significância estatística da inclinação das curvas de regressão foi considerada para o nível p<0,05. RESULTADOS: Foi observado decréscimo da taxa de mortalidade infantil de 48,5 para 22,1 por mil nascidos vivos em toda a região. Entretanto, a queda mais acentuada foi observada nos últimos quatro anos da série. O componente pós-neonatal foi o principal responsável pelo declínio tanto na capital como nos demais municípios que compõem a região metropolitana de Belo Horizonte. CONCLUSÕES: Embora tenha sido observada para a região uma queda significativa da mortalidade infantil e particularmente da mortalidade pós-neonatal, esta última ainda se apresenta elevada em relação aos países desenvolvidos. As afecções perinatais e o grupamento diarréia-pneumonia-desnutrição representam importante potencial de redução. Discute-se o papel dos serviços de saúde na evitabilidade de tais óbitos.

    Full Text Available The main objective of this cross-sectional study was to analyze factors associated with alcohol consumption among adult women living in Belo Horizonte, Minas Gerais State, Brazil, in 2011. Data for Belo Horizonte were obtained from the VIGITEL system (Telephone-Based Surveillance of Risk and Protective Factors for Chronic Diseases. Alcohol use was defined as self-reported intake of at least one dose in the previous 30 days; alcohol abuse was defined as four or more doses on at least one occasion during the same period. Polytomous logistic regression was used to evaluate factors associated with alcohol use and abuse. Alcohol use was more prevalent among women 25 to 34 years of age. Alcohol abuse was associated with age, schooling, health status, and smoking. The results suggest the need for policies to prevent alcohol abuse among women, especially targeting those who are younger, single, smokers, and with more education.

    Full Text Available The prevalence, virological and epidemilogical aspects of the hepatitis C virus (HCV and the hepatitis B virus (HBV infections vary among hemodialysis patients in different countries. Aiming at analyzing these aspects of HCV and HBV infections in hemodialysis patients in Belo Horizonte, MG, Brazil, we studied three hemodialysis units including 434 patients. Serology was used to detect anti-HCV and HBsAg. Reverse trancriptase nested polymerase chain reaction (RT-nested-PCR of the 5'-noncoding region was used to detect circulating HCV RNA and restriction fragment length polymorphism analysis for genotyping. Seroprevalence varied from 26.5% to 11.1% for hepatitis C and from 5.9% to 0% for hepatitis B. Risk factors observed for HBV and/or HCV infections were the number of patients per dialysis unit, duration of treatment, number of clinics attended, number of blood units transfused, and lower level scholarity. Alanine aminotransferase levels were altered with a higher frequency in HBV or HCV seropositive patients. Half of ten patients, negative for anti-HCV, had detectable viremia by RT-nested-PCR, indicating that this technique should be used to confirm infections in this group of patients. The HCV genotype 1 was the most frequently observed, followed by the genotype 2, but no correlation was detected between genotype and clinical or epidemiological data.

  7. Assessment of air quality in Mangabeiras' Park, Belo Horizonte, Brazil, using epiphytic lichens as biomonitor

    International Nuclear Information System (INIS)

    Biomonitoring has been used as an alternative method to study the air pollution in several countries. The lichen, or lichenized fungi, is one of the most efficient on air pollution biomonitoring among the biomonitors. However, in Brazil, systematic use of lichens as biomonitors of environmental pollution is quite rare. In order to make an assessment of the air quality of the Mangabeiras' Park, this study was conducted by measuring the concentration of elements accumulated in the lichen thallus. This park, located in Belo Horizonte (Minas Gerais, Brazil), is the greatest green area in the city, and an apparent region of non polluted air. During the development of the study, epiphytic lichens of several species were collected using a steel stainless knife, taking samples of similar sizes from 1.5 m from the soil. The lichens selection was based on morphological similarities, such as color and type of the thallus. The elemental concentration determination was carried out applying the neutron activation technique, k0-standardization method, using the TRIGA Mark I IPR-R1 research reactor located at CDTN/CNEN. The lichen samples presented expressive concentrations of Ba, Fe, K, Na and Zn. However, the presence of other characteristic soil elements from the region, such as As, Th and U, suggests the influence of the mining activity area, located in the surroundings. (author)

    Full Text Available AbstractLarge Brazilian cities, particularly those that have experienced rapid population growth since the middle of the last century, have exhibited significant signs of population dispersion in their peripheries in recent decades. A study of the population’s spatial redistribution in the Metropolitan Region of Belo Horizonte (MRBH confirms this finding. In the process of dispersion, the levels of urban commuting increase, and commuting becomes a relevant indicator of the degree of integration within the metropolis. This paper evaluates the current magnitude and main features of reverse commuting, as characterized by the daily displacements of the population that resides not in the periphery but rather in the core. Flows from the metropolitan core towards the peripheral municipalities are examined using sample microdata on the MRBH municipalities from the 2000 and 2010 demographic censuses by combining the variables of "municipality of residence" and "municipality of work/study." The results indicate an increase in reverse commuting in both absolute and relative terms. When this flow is compared totraditional commuting (periphery/center, the relative values are considerable. In some cases, this relationship reaches notably high values, as the case of Confins (the municipality where the international airport is located, and also municipalities that are part of a relatively old conurbation, such as Nova Lima and Betim.

    Full Text Available This article aims to analyze the concepts of leisure and education that permeate the documents in the Integrated School Program in Belo Horizonte. The analysis was based on the Policy cycle approach and emphasized the contexts of influence and the policy text production. Thus, the formation of the political agenda, the Political Pedagogical Project Program and the Strategic Plan 2010-2030 BH were investigated. The policy context is not organized in a linear fashion; it is a process of groups of interest interaction. With the discourse of coping with school failure, revealed by the students’ yield and flow evaluation indices (approval, repetition and dropout, the Integrated School education documents announce education and leisure as forms of production, strengthening links between public and private. The right to education is restricted to children’s and youth’s access and permanence in school without creating a perspective of universalization and quality. The documents address the leisure with a simplistic view of construction and maintenance of equipment and the idea of activity

  14. An econometric study of illegal electricity connections in the urban favelas of Belo Horizonte, Brazil

    International Nuclear Information System (INIS)

    The data from the project 'Conviver,' launched in 2006 in Belo Horizonte (Brazil), provides a unique opportunity to study illegal electricity connections. Based on an original dataset of 15,279 low-income households, this paper studies the incidence and determinants of illegality in the context of low-income urban favelas. The probability of engaging in illegal behavior is explained not just by low income, but by a combination of concurring factors: sub-standard energy provision and equipment; inefficient/incorrect use of domestic electric appliances and running an informal in-house business. These recurrent issues in the urban favelas aggravate a sense of exclusion from growth, which is generally recognized as a trigger of illegality. The impact of energy demand on energy-related illegality is carefully analyzed, and different empirical strategies adopted to circumvent some simultaneity problem between both decision processes. The effectiveness of consumption-based energy subsidies is also explored. In spite of some contrary arguments in the literature, in the context of peri-urban slums, such measures may exert a positive impact in mitigating illegal access and use of energy. Effectiveness will be enhanced by accompanying measures such as: perceivable improvements of equipment, metering and maintenance, promotion of beneficiaries' awareness of energy usage, and energy-saving behaviors.

    The main sources of radon concentration in buildings are the underground surrounding soil and bedrock, construction materials and underground water supply. However, the contribution from these sources to the indoor radon level depends on many factors, such as type of the building, geology and pedology of the site and also the floor level. Focusing on this concern, the present work outlines on the characterization of the radon concentration in two different kinds of buildings - slab-on-grade dwellings and apartments on the second floor and above - in the Metropolitan Region of Belo Horizonte, Brazil, which is located in a large part on granite embasement area, the Granitic Gnaissic Complex. The radon concentration in dwellings and apartments, measured by using E-PERM Electrets Ion Chamber, ranged from 18.5 to 1591.0 Bqm{sup -3} (mean value 114.7 {+-} 5.5 Bqm{sup -3}) and 3.7 to 185.0 Bqm{sup -3} (mean value 70.3 {+-} 6.7 Bqm{sup -3}), respectively. Thus, the highest radon concentration is present in dwellings not in apartments, suggesting that the enhanced radon concentration maybe was originated mainly from local geological settings instead of other sources. In order to confirm this hypothesis, the measurements of the soil gas radon concentration were carried out by using AlphaGUARD PQ2000PRO detector and {sup 226}Ra ({sup 214}Bi) and {sup 224}Ra ({sup 212}Pb) specific activity in construction materials were determined by using gamma-ray spectrometry HPGe detector. These results confirmed the local geological setting as the main radon source. Moreover, radon concentration much higher than United States Environmental Protection Agency USEPA action level 148Bq.m{sup -3} occurred only in slab-on-grade dwellings. (author)

    Radon is a radioactive noble gas derived from the natural decay series of {sup 238}U, {sup 235}U, and {sup 232}Th, which are present in rocks and soils. By diffusion and convection, radon migrates from the rocks and soils to the surface and through fissures, pipes and holes it may enter the dwellings and other buildings. Another important indoor radon source is the building material construction. Therefore, it may accumulate indoor environments with reduced ventilation rates. Radon progeny attach to the aerosol particle in the air. The attached and unattached radon progeny may deposit in the lungs and irradiate to the lung tissue as they decay. Radon has been recognized as a radiation hazard, that causes excess of lung cancer among underground miners and there is an evidence that radon is also a heath hazard in dwellings and other indoor environments. Radon accounts for about half of all human exposure to natural radiation. Radon concentration measurements were carried out in dwellings, schools and shopping centers in the Metropolitan Region of Belo Horizonte - RMBH. Most part of the inhabitants of the RMBH lives over the granitic gneissic complex, which has a variable depth out coming in some areas. For the radon concentration measurement continuous detectors, AlphaGUARD PQ2000PRO, RAD7 and Pylon Lucas Cells were used and, for Potential Alpha Energy Concentration-PAEC measurement a solid state alpha spectroscope, the DOSEman PRO was used. The experiments showed that most results are below 50 Bqm{sup -3} (mean+3{sigma}). This value is bellowing the action levels of the USEPA, ICRP and others, which varies in the range from 148 to 200 Bqm{sup -3}. The values are in the low range, as it was expected for a tropical climate. (author)

Methods: This was a cross-sectional study conducted with 267 randomly selected school students aged between 6 and 16 years. students underwent anamnesis and physical examination with the purpose of establishing criteria for the diagnosis of rheumatic fever. They were all subjected to Doppler echocardiography using a portable machine. Those who exhibited nonphysiological mitral regurgitation (MR and/or aortic regurgitation (AR were referred to the Doppler echocardiography laboratory of the Hospital das Clínicas of the Universidade Federal of Minas Gerais (HC-UFMG to undergo a second Doppler echocardiography examination. According to the findings, the cases of rheumatic heart disease were classified as definitive, probable, or possible. Results: Of the 267 students, 1 (0.37% had a clinical history compatible with the diagnosis of acute rheumatic fever (ARF and portable Doppler echocardiography indicated nonphysiological MR and/or AR in 25 (9.4%. Of these, 16 (6% underwent Doppler echocardiography at HC-UFMG. The results showed definitive rheumatic heart disease in 1 student, probable rheumatic heart disease in 3 students, and possible rheumatic heart disease in 1 student. Conclusion: In the population under study, the prevalence of cases compatible with rheumatic involvement was 5 times higher on Doppler echocardiography (18.7/1000; 95% CI 6.9/1000-41.0/1000 than on clinical evaluation (3.7/1000-95% CI.

    Full Text Available In this paper, we present spatial analysis of the association between all incidents cases of human Visceral Leishmaniasis and seropositive dogs, from 1994 to 1997 in Belo Horizonte, a large Brazilian city. We geocoded 158 human cases and 11,048 seropositive dogs and compared canine prevalence rates with Human Bayesian Incidence rates in the same areas. We also used Knox's test to evaluate the hypothesis of space-time clustering of human cases in the period. Additionally, we used Kernel's maps for seropositive dogs distribution and located the human cases in the resulting smooth maps. We concluded that human and dog rates are correlated. Also, the Visceral Leishmaniasis in Belo Horizonte spread quickly, but apart from the rates' magnitude, it has kept the same spatial pattern through time. We believe it is possible to use this technique to choose areas to implement control measures against Visceral Leishmaniasis in a more efficient way.Neste artigo, apresentamos uma análise espacial da associação entre todos os casos incidentes de leishmaniose visceral e em cães soropositivos ocorridos em Belo Horizonte no período de 1994 a 1997. Geocodificamos 158 casos humanos e 11.048 cães positivos, comparamos as taxas de prevalência canina por área e as taxas Bayesianas de incidência da doença humana nas mesmas áreas. Usamos o teste de Knox para testar a hipótese de cluster espaço temporal entre os casos humanos no período examinado. Adicionalmente, construímos Mapas de Kernel para cães soropositivos e sobrepusemos os casos humanos em quatro áreas. Os resultados apontam para correlação entre casos humanos e caninos. Além disso, a leishmaniose visceral espalhou-se rapidamente em Belo Horizonte, embora tenha mantido o mesmo padrão durante os anos analisados. Acreditamos ser possível o uso das técnicas empregadas para priorizar áreas onde as medidas de controle devem ser implementadas.

    Full Text Available A cidade tem sido encarada tradicionalmente na Administração sob a ótica funcionalista, ao ser entendida como campo de atuação profissional ou objeto da administração pública e gestão urbana. Todavia, estudos que versam sobre a urbes em uma perspectiva não-funcionalista tem se tornado cada vez mais recorrente, principalmente, a partir de uma visão que focaliza a complexidade urbana e evoca a vida social organizada de indivíduos e grupos oprimidos em diversos âmbitos sociais. Neste artigo buscamos analisar os discursos que orientam práticas organizativas relacionadas à pichação em Belo Horizonte, o que foi feito mediante um estudo qualitativo baseado em análise do discurso. Além de pesquisa em documentos oficiais sobre as ações governamentais no combate à pichação, foram efetuadas entrevistas individuais em profundidade com nove sujeitos, entre gestores públicos municipais responsáveis pelo combate à pichação, indivíduos da sociedade civil participantes das ações do projeto municipal, e representantes da pichação belo horizontina. O tratamento dos dados foi efetuado por meio da análise do discurso francesa, pela qual se buscou a identificação e análise de aspectos e elementos discursivos segundo roteiro constituído por: i seleções lexicais; ii percursos semânticos; iii interdiscursividades; iv discursos principais; v reflexão e refração linguísticas; vi aspectos ideológicos combatidos e defendidos; e vii posicionamentos discursivos em relação aos discursos hegemônicos na sociedade. Os principais resultados sugerem que o governo da cidade tanto orienta as representações de combate à pichação como é pressionado para enfrentar o fenômeno segundo os vários modos de fazer, pelos quais imperam os instrumentos de controle sobre as práticas de organização da cidade e se instituem agentes sociourbanos de legitimação estratégica. Conclui-se que a gestão pública é ressignificada pelos

It concludes that the relative success achieved when inaugurating city master plans, participatory budgeting (where civil society has direct input in budget definitions, and sectoral councils (councils for decentralized policy issue areas is linked to three factors: prior decentralization processes; articulation between different decision-making units; and, above all, the neutralization of clientelistic control mechanisms through the introduction of horizontal loyalty networks and spaces of representation that in the final analysis will foster greater social capital and accountability.

    Full Text Available Apesar de jovem (inaugurada em 1897 Belo Horizonte passou por um relativo processo de esvaziamento de seu centro histórico com a demolição de alguns edifícios, o deslocamento das moradias de classe média para outras regiões, a diminuição de áreas de espaço público de convivência e da presença da elite nessa região. Como em diversas cidades, esse processo mobilizou agentes públicos e iniciativa privada na elaboração de projetos de requalificação urbana voltados para sua área central. A proposta deste trabalho é refletir sobre a forma como esses projetos vêm sendo implementados pelo poder público e a região requalificada vem sendo apropriada pelos diferentes atores. Nossa hipótese é de que os processos de requalificação urbana em Belo Horizonte não devem ser pensados como intervenções voltadas apenas para o mercado, o entretenimento e o consumo cultural, numa palavra, a gentrificação

    This article evaluates government measures to reduce inequity in the health sector in Belo Horizonte from 1993 to 1997. Our hypothesis is that a municipal administration committed to equity can reduce disparities in health with the support of the Unified National Health System (SUS). The methodology used an urban quality of life index in Belo Horizonte to detect social inequalities in living conditions, as well as differences between the component indices in the infant mortality rate. Other municipal measures were assessed according to the investment resulting from the implementation of a participatory local budget and open planning process. The urban quality of life index appeared to be an appropriate measure for orienting municipal administration. The infant mortality rate proved to be a good indicator for measuring inequality in health. There was a reduction in IMR and mortality reducing gaps in the districts studied. We observed greater investment of physical and financial resources in the districts with the lowest urban quality of life index, and it can thus be stated that the municipal administration reduced the prevailing inequalities.

MÉTODOS: Com base nos dados do Programa Fica Vivo, de prevenção de homicídios, foi realizado um estudo quase experimental com análise de séries temporais da ocorrência de homicídios no aglomerado Morro das Pedras, em Belo Horizonte, MG, de 2002 a 2006. Comparou-se o número de homicídios ocorridos nessa localidade com os de outras favelas violentas e não violentas e outros bairros da cidade, em cada uma das fases do Programa. Para testar a hipótese de que a redução dos homicídios resultou das ações implementadas pelo Programa, foi elaborado um modelo estatístico baseado em modelos lineares generalizados. RESULTADOS: Nos primeiros seis meses obteve-se 69% de redução no número médio de homicídios. Nos períodos de refluxo e retomada parcial do Programa, o efeito de redução dos homicídios diminuiu, mas a diferença entre coeficientes com aquele do período inicial não foi estatisticamente significante. Mesmo com a retomada integral do Programa, o efeito continuou similar aos dos períodos anteriores, provavelmente porque o Programa foi implantado em outras favelas violentas da cidade. CONCLUSÕES: Os resultados apontam que o modelo do Programa Fica Vivo pode constituir uma importante alternativa para prevenção de homicídios contra jovens em comunidades que apresentem características semelhantes às da experiência piloto no Morro das Pedras.OBJETIVO: Evaluar el impacto del programa de prevención de homicidios.

É possível estudá-los pela observação da prevalência de agravos nas populações, bem como das causas de mortalidade, buscando-se uma correlação com os hábitos sociais e origens étnicas e familiares dos indivíduos. Nestes estudos, destacam-se as comunidades nas quais podem-se verificar vínculos sociais e genéticos entre seus membros. A comunidade judaica de Belo Horizonte se encaixa nesses critérios. Ela se consolidou na década de 20 do século passado e, atualmente, a Federação Israelita de Minas Gerais (FISEMG tem cadastro de aproximadamente 600 famílias. Este estudo pretende definir o padrão de mortalidade nessa comunidade, e como ele se modificou a partir de sua formação. MÉTODOS: Foram recuperados dados a partir dos arquivos do Instituto Histórico Israelita Mineiro, da FISEMG e dos Cemitérios Israelita e do Bonfim, oriundos de registros históricos e guias de sepultamento, no período de 1926 a 2003. RESULTADOS: Foram estudados 601 registros de óbitos, sendo 61,6% de homens e 38,4% de mulheres. As doenças infecto-parasitárias, dentre elas a tuberculose, ocorreram com maior freqüência nas décadas de 30 e 40 e decresceram nas décadas seguintes. As doenças do aparelho circulatório foram as causas de óbito mais prevalentes a partir da década de 40. CONCLUSÃO: Houve mudança nos padrões de mortalidade da população judaica de Belo Horizonte.OBJECTIVE: Genetic and environmental factors are known for their importance in the genesis of the majority of diseases.

    Full Text Available Objective: In order to identify intraurban differentials, the prevalence of major protection and risk factors for non communicable chronic diseases were analyzed in nine health districts of Belo Horizonte, Minas Gerais, Brazil. Methods: Analysis of data from a telephone survey conducted with 2,000 adults in Belo Horizonte, in 2010, using the average linkage method for cluster analysis among the health districts, using sociodemographic variables (education, race and marital status. The study compared the prevalence of risk factors for non communicable diseases among the health districts. Results: Four clusters were identified. The best socio-demographic indicators were found in cluster 4 (South Central health district, which also showed a higher prevalence of protective factors such as higher consumption of fruits and vegetables, higher frequency of physical activity practice in the free time, use of ultraviolet protection, higher proportion of ex-smokers, and lower prevalence of whole milk and high-fat meat consumption. As a risk factor, cluster 4 showed a higher proportion of alcohol abuse. Cluster 1, with the worst socio-demographic indicators, concentrated more risk factors such as consumption of whole milk, low regular consumption of fruit and vegetables, and lower practice of physical activity in the free time. The most frequent protective indicators in cluster 1 were the regular consumption of beans, having breakfast at home, and lower alcohol abuse. Conclusion: Intra-urban differences were found in the distribution of risk and protection factors or non transmissible diseases, these differences can support planning aimed at actions for greater equity in health.

    Full Text Available Diante da escassa elaboração de pesquisas sobre a rotatividade da força de trabalho no setor público de saúde no Brasil, este estudo objetivou avaliar o índice dessa rotatividade na rede municipal de saúde de Belo Horizonte, Minas Gerais. A partir de reconhecida inscrição na literatura de um parâmetro para o índice de rotatividade na área hospitalar e com base na distribuição da frequência observada neste estudo, formalizou-se um novo parâmetro para a rede ambulatorial, bem como valores para os pontos de corte no que concerne à classificação dos seus níveis qualiquantitativos. Tais valores subsidiaram a análise do comportamento do índice de rotatividade em relação às seguintes variáveis: vínculos empregatícios, distritos sanitários, serviços de atenção à saúde, categorias profissionais e atenção primária e secundária à saúde. O índice geral de rotatividade na rede municipal no período estudado (julho de 2008 a junho de 2009 foi de 8,35%, que, mesmo diante da dificuldade de construção da base de dados, a qual adveio da existência de distintas fontes de informação, apresenta, em termos estatísticos, validade interna.Given the scarcity of studies on workforce turnover rates in the public health care industry in Brazil, the purpose of this study was to assess this rate in the municipal health care network of Belo Horizonte, Minas Gerais.

    Pollution caused by the electromagnetic fields (EMFs) of radio frequencies (RF) generated by the telecommunication system is one of the greatest environmental problems of the twentieth century. The purpose of this research was to verify the existence of a spatial correlation between base station (BS) clusters and cases of deaths by neoplasia in the Belo Horizonte municipality, Minas Gerais state, Brazil, from 1996 to 2006 and to measure the human exposure levels to EMF where there is a major concentration of cellular telephone transmitter antennas. A descriptive spatial analysis of the BSs and the cases of death by neoplasia identified in the municipality was performed through an ecological-epidemiological approach, using georeferencing. The database employed in the survey was composed of three data banks: 1. death by neoplasia documented by the Health Municipal Department; 2. BSs documented in ANATEL ('Agencia Nacional de Telecomunicacoes': 'Telecommunications National Agency'); and 3. census and demographic city population data obtained from official archives provided by IBGE ('Instituto Brasileiro de Geografia e Estatistica': 'Brazilian Institute of Geography and Statistics'). The results show that approximately 856 BSs were installed through December 2006. Most (39.60%) of the BSs were located in the 'Centro-Sul' ('Central-Southern') region of the municipality. Between 1996 and 2006, 7191 deaths by neoplasia occurred and within an area of 500 m from the BS, the mortality rate was 34.76 per 10,000 inhabitants. Outside of this area, a decrease in the number of deaths by neoplasia occurred. The greatest accumulated incidence was 5.83 per 1000 in the Central-Southern region and the lowest incidence was 2.05 per 1000 in the Barreiro region. During the environmental monitoring, the largest accumulated electric field measured was 12.4 V/m and the smallest was 0.4 V/m. The largest density power was 40.78 {mu

The methodological approach is based in social representations theory and in the critical discourse analysis of 101 texts - from the press and from public agencies or government representatives. Our results suggest that current political strategies were not fully exploiting the potential for interaction and collective construction offered by the Internet, trivializing it. This may be one of the reasons of lower participation.

The survey of the population consisted of 1119 interviews and 881 clinical examinations using Montenegro's skin test (MST. A low prevalence (3.7% of positive MST was encountered. The disease had been occuring in the area for about 20 years in the form of sporadic cases. The predominant species of sandfly both in domestic areas and nearby areas of secondary vegetation was Lutzomyia whitmani. A canine survey of delayed hypersensitivity to the antigen P10,000 identified only one dog with a positive reaction out of 113 examined. The transmission of ACL in MRBH was confirmed. The occurrence of the disease in women, children and individuals with no contact with forest areas as well as the presence of potential vector species in the domiciliar environment, suggests the transmission of the disease in this environment.

Este resgate se fez através da sua história cronológica e das construções narrativas e discursivas sobre a epidemia em 101 matérias publicadas na grande imprensa, durante o período de 1993 a 1996. Utilizando-se como orientação metodológica a proposta de Foucault (1972, em seu trabalho "A Arqueologia do Saber", a análise aponta para a configuração de três grandes discursos, caracterizando grupos temáticos, nas matérias estudadas: o da Ciência, o do Estado e o da Sociedade. Cada um dos grupos contribui para a construção da doença no espaço jornalístico e veicula opiniões próprias de cada um destes universos. Dessa forma, a leitura dos textos jornalísticos permite o desnudamento de outro processo epidêmico, que se desenvolve paralelamente àquele que acomete as populações humana e canina, expresso nas construções narrativas sobre a leishmaniose visceral nos textos de jornal.

    This study aimed to assess the relationship between perception of temperature inside the bus and hypertension among 1126 collective transportation workers in metropolitan region of Belo Horizonte, Brazil. Thermal discomfort was determined based on the perception of temperature inside the bus. Hypertension was determined if participant had a medical diagnosis of this disease. Prevalence ratios (PR) for hypertension and their respective 95% confidence intervals (95% CI) were adjusted using multivariate Poisson regression analysis. The perceptions of temperature inside the bus were tolerable (26.5%), disturbs a little (28.6%), disturbs a lot (34.8%) and unbearable (10.2%). The prevalence of hypertension was 14.3%. The thermal discomfort categories of disturbs a lot (PR = 1.41; 95% CI = 1.02-1.95) and unbearable (PR = 1.75; 95% CI = 1.16-2.63) were independently related to hypertension. Thermal discomfort was associated with a higher prevalence of hypertension. This finding should be considerate in new policies for public transportation.

Os instrumentos de coleta utilizados foram entrevistas semi-estruturadas e grupo focal, tendo sido os dados analisados à luz da análise crítica de discurso.

O R. neglectus nesta região parece apresentar uma unica geração anual, com possibilidade de duas, sendo que o periodo de oviposição se relaciona com os meses quentes do ano, coincidindo com a predominância de formas jovens sobre os adultos. A observação sugere que a densidade populacional do R. neglectus no seu ecotopo natural possa estar relacionada com a disponibilidade de alimento e com a presença de predadores como o Telenomus sp., formigas, aranhas, hemipteros, escorpiões e pseudo-escorpiões. O indice global de infecção pelo Trypanosoma cruzi foi de 15,9%, indicando o R. neglectus como um importante vetor silvestre deste tripanosomatídeo cuja principal fonte e constituída por marsupiais. O R. neglectus na regiao encontra-se estreitamente associado a palmeira de macaúba, e as aves que as frequentam constituem sua principal fonte alimentar. As observações não sugerem o R.neglectus como uma espécie transmissora do T. cruzi ao homem nesta região.Eighty-one "macaubeiras" palm-trees (Acrocomia sclerocarpa from the periophery of Belo Horizonte city were cut down and dissected between April 1979 and July 1980. 60,5% of the trees were positive for R. neglectus and 463 specimens of this insect were collected, providing a mean rate of 9,45 individuals for positive palm-trees. R neglectus seems to present a single annual generation in this region, but evidence was obtained that two generations may occur. Its spawn period is related to the hot months of the year, when younger insects prevail over the adults. This observation suggests that higher population desities are related to better feeding conditions and to minor desities of

    Full Text Available Mycoplasma gallisepticum (Mg infection of wild native Brazilian psittacines (Psittaciformes which died of any cause during sorting, rehabilitation, or conservation, was investigated by PCR. Two previously described PCR methodologies using Mg specific primers were employed for the analyses of 140 swab samples (cloaca, trachea, or palatine cleft. Average positive Mg detection in cloacal swabs was 51.9%, with 80.0% (n=5 of Blue-and-yellow Macaws (Ara ararauna, 60.0% (n=3 Dusky Parrots (Pionus fuscus, 52.5% (n=59 Amazon Parrots (Amazona aestiva, 50.0% (n=2 Orange-winged Parrots (Amazona amazonica, 50.0% (n=2 Jandaya Parakeetsor Jandaya Conures (Aratinga jandaya, 0% (n=2 Golden Conures or Golden Parakeets (Guarouba guarouba, and 0% (n=2 Hyacinth Macaws (Anodorhynchus hyacinthinus. Palatine cleft swab sampling was more sensitive to detect Mg, with 85.4% (n=17 detection rate, as compared to 67.4% (n=46 obtained with tracheal samples, and 53.5% (n=77 with cloacal swabs. The surprisingly high Mg incidence in psittacines kept in conservation or triage environments is possibly due to the proximity or cohabitation with several bird species during confinement and housing psittacines of different origins together. The implementation of biosecurity measures and species-specific facilities is recommended.

Dentro deste contexto, as pesquisas sobre comprometimento organizacional têm se revelado pertinentes, sendo objeto de estudo para um grande número de administradores e pesquisadores. Portanto, com o objetivo de contribuir com o incremento do conhecimento sobre o construto comprometimento organizacional, esta pesquisa foi desenvolvida em duas empresas do setor varejista do comércio da cidade de Belo Horizonte. Quanto aos métodos de pesquisa este estudo caracteriza-se como quantitativo e descritivo. Valendo-se de um modelo teórico – Modelo das Três Dimensões de Meyer e Allen (1997 - testado e validado no Brasil, foram pesquisados os graus e tipos de comprometimento dos vendedores e gerentes com a organização. Os resultados encontrados, em ambas as redes de lojas, indicaram um grau moderado de comprometimento – afetivo, normativo, instrumental. Por fim, apresentaram-se as implicações acadêmicas e práticas, bem como as limitações deste estudo e recomendações para futuras pesquisas.

Comparados aos pacientes com LC, aqueles com LM apresentaram maior tempo de doença e relato de outras doenças concomitantes, sugerindo que a debilitação pela leishmaniose e/ou outras doenças podem contribuir para a ativação e/ou disseminação mucosa do parasito. As sensibilidades das reações intradérmica, de imunofluorescência indireta e da pesquisa direta do parasito foram de 78,4, 79,3 e 68,3%, respectivamente. O tratamento com antimoniato de meglumina foi 100% eficaz, com 59% de efeitos colaterais ao longo do tratamento. A recidiva após tratamento ocorreu em 32 (10,1% dos 318 casos seguidos por até dois anos. A maioria das recidivas (31 dos 32 casos ocorreu em pacientes com LC tratados com 15mg Sb5+/kg/dia. Na investigação de critérios de cura, a reação intradérmica negativa foi o único fator associado a um risco três vezes maior de recidiva. Um aumento da dose ou do tempo de tratamento talvez melhore o prognóstico nestes pacientes.

Utiliza-se o modelo de preços hedônicos para estimar o custo da violência - homicídios e roubos a transeuntes - implícito no preço dos imóveis residenciais, a partir de uma amostra com imóveis transacionados em Belo Horizonte. Duas regressões foram rodadas para que pudessem captar a disposição a pagar dos indivíduos para residirem em regiões de maior segurança.

Such economy seeks to explain how there is the regularity of the urban residential setting from the action of individuals in the market. The hedonic price model is used to esteem the implicit violence costs (e.g. homicides and robberies to pedestrians in housing prices, from a sample of properties transacted in Belo Horizonte. Two regressions that could capture the willingness of individuals to pay for living in regions with greater security were shot. The results show that there is a relationship between the reduction in crime rates and valuation of properties in some Belo Horizonte regions.

    The present article describes the occurrence of 17 cases of acute schistosomiasis in the metropolitan area of Belo Horizonte, state of Minas Gerais, Brazil. All individuals affected took a bath in a swimming pool of a holiday resort that was provided with water from a nearby brook. The apparently clean water and the absence of snails in the pool gave the wrong impression that there was no risk for infection. During a malacological survey at the site snails of the species Biomphalaria glabrata were found and tested positive for Schistosoma mansoni. All the patients live in the middle-class area of Barreiro, metropolitan area of Belo Horizonte and have medium grade school education. The difficulties in establishing the right diagnosis is expressed by the search for medical attention in 17 different medical facilities, the wide range of laboratory test and the inadequate treatment administration. A lack of knowledge about the disease was found in all groups studied. The booming rural tourism in endemic areas is identified as a probable risk factor for infection, especially for individuals of the non-immune middle and upper class parts of the society in urban centers. Special attention is given to a multidisciplinary approach to the complex issue of disease control and prevention. PMID:14595449

Para tal, foram entrevistados indivíduos que adquiriram fitoterápicos nos estabelecimentos farmacêuticos visitados. Observa-se que, na mesma nação detentora da maior biodiversidade do planeta e privilegiada por uma cultura popular conhecedora das propriedades terapêuticas das plantas, existe uma tendência de mercado para a utilização de plantas exóticas, oriundas de países desenvolvidos. A influência da legislação brasileira de fitoterápicos, que prima pela qualidade, eficácia e segurança desses medicamentos, mas que, ao mesmo tempo, tende a proscrever as drogas nativas que fazem parte da medicina popular brasileira, é discutida nesse trabalho. Verifica-se, assim, a pertinência de se discutir o perfil de usuário de fitoterápicos à luz das normas de registro desses fármacos no país no campo da saúde pública, tendo em vista que essa legislação repercute nas estratégias e/ou empecilhos para aumentar o acesso a medicamentos pela população.An overview of the herbal drugs consumption in communitarian pharmacies in Belo Horizonte (MG, Brazil is used in this article as a tool to analyze the influence of the national law over this market.

Em apenas seis anos, protagonistas diversos participaram de eventos marcantes, em torno da construção de uma nova capital, que redefiniram lugares de sociabilidade e modos de viver. Nascia Belo Horizonte, planejada e construída para ser a capital das Minas Gerais, vitrine da República, com suas praças, ruas e avenidas projetadas a régua e compasso. A pretensão era obrigar seus habitantes, antigos e novos, a "nascer de novo" com ela, como a poesia de Drummond de Andrade sintetiza. É em meio a tantas e tais vicissitudes que procuramos examinar, em diferentes espaços de sociabilidade urbana da nova capital, dispositivos de natureza diversa que encontravam no corpo o seu destino, como lugar de uma educação, de um cultivo, de uma civilização.The advent of the Republic in the last decade of 1800 was to Minas Gerais state a significant experience. In only six years, several protagonists were involved in remarkable events related to the building of the new capital city, which redefined the places for socialization and different lifestyles. The city of Belo Horizonte was born, planned and built to become the capital of Minas Gerais, a model for the Republic, with its squares, streets and avenues accurately projected with 'rulers and compass'. The main purpose was to make its old and new dwellers 'be born again' with Belo Horizonte, as later summed up in Drummond de Andrade's poem. Based on these aspects, our study focused on examining in different places of urban socialization provided by the new capital city different devices that found in people's bodies their destination, as a place for education, cultivation and civilization.

    The objective of this study was to estimate the prevalence of hearing impairment in children in a public hospital in Belo Horizonte, Minas Gerais, Brazil, and to investigate the association with risk factors described in the literature. This study was cross-sectional and retrospective and analyzed 798 newborns and infants evaluated in the Universal Neonatal Hearing Screening Program from June 2002 to December 2003. The risk factors established by the Joint Committee on Infant Hearing in 1994 and Azevedo in 1996 were studied, besides prematurity. Prevalence of hearing impairment was 1.8% (15 cases). A multivariate logistic regression analysis was used to verify associations between risk factors and hearing impairment, showing a significant statistical association (p ototoxic drugs, and low birth weight. A significant prevalence of hearing impairment in neonates and infants was confirmed. Attention should thus be focused on risk factors for hearing impairment, using hearing programs that ensure prevention, early detection, and intervention.

The focus of this analysis rests on an innovative new tool available to the OP-BH: the operationalization of the Digital Participatory Budget (OP-Digital. E-democracy is therefore the strategy "right" for the current time of OP-BH, reducing political patronage? What is the synergy between the exercise of democratic practice, the use of electronic media and participatory process to strengthen the quality of democracy in that it increases the interaction between the citizen and the executive branch? With use of secondary data and interviews with municipal managers and the population of the city of Belo Horizonte, anchored by a literature review. The prospect is that this work will contribute to better defining the concept of political participation and the relationship between the executive and local civil society. The findings indicate a qualitative and quantitative expansion of popular participation in decision-making budget and an important contribution to the model of political communication, along the lines of a "digital democracy", in which the process of voicing the concerns of civil society and the mechanisms social control are expanded significantly.

    Belo Horizonte, the capital of the southeastern state of Minas Gerais, Brazil, and the fourth-largest city in the country, has the highest incidence of human visceral leishmaniasis (VL) together with a high prevalence of canine VL. The Northeast Sanitary District (NSD) of Belo Horizonte has the largest historical average of human VL cases in the metropolitan region, and is classified as a priority area for epidemiological and entomological monitoring of the disease. The objectives of the present study were to determine the seasonal variation in phlebotomine fauna and to describe the environmental situations in the NSD through characterization of peri-domiciles and application of geographical information system analysis. Entomological captures were performed every two weeks during the period July 2006 to June 2007 using HP light traps placed at 16 locations where cases of human VL had been reported in 2005. The environmental characterization of these locations was accomplished using forms and photographic images. Spatial analyses was used to determine the influence of vegetation, hydrography, altitude and pockets of poverty on the occurrence of cases of human and canine VL, and of phlebotomine vectors. A total of 633 phlebotomines belonging to the subtribes Psychodopygina and Lutzomyina were captured and, of these, 75% were identified as Nyssomyia whitmani and 11% as Lutzomyia longipalpis. The majority of the studied peri-domiciles presented inadequate hygienic conditions that would favor the development of phlebotomines. No significant correlations could be established between biogeographical aspects and either the incidence of human and canine VL or the occurrence of phlebotomines. The proximity of areas with vegetation, villages, slums and open watercourses exerted little influence on the incidence of VL. These findings reinforce the urbanization of the VL profile since the disease occurred in locations where conditions that have been classically related to its

    Full Text Available Introduction The aim of this study was to determine the antimicrobial susceptibility of Neisseria gonorrhoeae isolates obtained from patients attending a public referral center for sexually transmitted diseases and specialized care services (STD/SCS in Belo Horizonte, Brazil. Methods Between March 2011 and February 2012, 201 specimens of Neisseria gonorrhoeae were consecutively obtained from men with symptoms of urethritis and women with symptons of cervicitis or were obtained during their initial consultation. The strains were tested using the disk diffusion method, and the minimum inhibitory concentrations of azithromycin, cefixime, ceftriaxone, ciprofloxacin, chloramphenicol, penicillin, tetracycline and spectinomycin were determined using the E-test. Results The specimens were 100% sensitive to cefixime, ceftriaxone and spectinomycin and exhibited resistances of 4.5% (9/201, 21.4% (43/201, 11.9% (24/201, 22.4% (45/201 and 32.3% (65/201 to azithromycin, ciprofloxacin, chloramphenicol, penicillin and tetracycline, respectively. Intermediate sensitivities of 17.9% (36/201, 4% (8/201, 16.9% (34/201, 71.1% (143/201 and 22.9% (46/201 were observed for azithromycin, ciprofloxacin, chloramphenicol, penicillin and tetracycline, respectively. The specimens had plasmid-mediated resistance to penicillin PPNG 14.5% (29/201 and tetracycline TRNG 11.5% (23/201. Conclusions The high percentage of detected resistance to penicillin, tetracycline, chloramphenicol and ciprofloxacin indicates that these antibiotics are not appropriate for gonorrhea treatment at the Health Clinic and possibly in Belo Horizonte. The resistance and intermediate sensitivity of these isolates indicates that caution is recommended in the use of azithromycin and emphasizes the need to establish mechanisms for the surveillance of antimicrobial resistance for the effective control of gonorrhea.

    Intense mining activities in Minas Gerais State, Brazil. Iron Quadrangle, the central region of Minas Gerais State- Brazil, has important mineral reserves of Fe (the World's second largest iron ore producer), Mn, Cu, Sb, As, Au, Al, and U. The intense mining activities in Minas Gerais State throw out tons of waste in the open air, water, sediment and soil. The considerable accumulated concentrations of heavy metals and toxic elements penetrate the soil, underground waters, rivers, and lakes jeopardizing the environment quality. A great amount of heavy metals enter Pampulha Reservoir via it's main tributaries (Sarandi and Ressaca). Although no water quality classification has been carried out for these tributaries, the reservoir is expected to be in class 2 of the CONAMA-86 system. The Pampulha Lake is a depth of 8 m and an area of 43 km2, in a hot, humid climate with a summer rainy season, >18 degree C in the coldest months. A great number of persons use the water for fishing and swimming in the contaminated water. The figure l localizes the Pampulha Lake in Brazil. Instrumental Neutron Activation Analysis, INAA, and Inductively Coupled Plasma-Mass Spectrometry-High Resolution, ICP-MSHR, were applied to determine Al, As, B, Ba, Co, Cr, Cs, Cu, Fe, K, Mg, Mn, Mo, Na, P, Pb, Rb, Zn and Ti. Instrumental Neutron Activation Analysis - INAA is based in a simultaneous irradiation compareson between standard and studied samples in a nuclear reactor.

Other municipal measures were assessed according to the investment resulting from the implementation of a participatory local budget and open planning process. The urban quality of life index appeared to be an appropriate measure for orienting municipal administration. The infant mortality rate proved to be a good indicator for measuring inequality in health. There

    Full Text Available Introduction Dengue is prevalent in many tropical and sub-tropical regions. The clinical diagnosis of dengue is still complex, and not much data are available. This work aimed at assessing the diagnostic accuracy of the tourniquet test in patients with suspected dengue infection and its positivity in different classifications of this disease as reported to the Information System for Notifiable Disease in Belo Horizonte, State of Minas Gerais, Brazil between 2001 and 2006. Methods Cross-section analysis of the diagnostic accuracy of the tourniquet test for dengue, using IgM-anti-DENV ELISA as a gold standard. Results We selected 9,836 suspected cases, of which 41.1% were confirmed to be dengue. Classic dengue was present in 95.8%, dengue with complications in 2.5% and dengue hemorrhagic fever in 1.7%. The tourniquet test was positive in 16.9% of classic dengue cases, 61.7% of dengue cases with complications and 82.9% of cases of dengue hemorrhagic fever. The sensitivity and specificity of the tourniquet test were 19.1% and 86.4%, respectively. Conclusions A positive tourniquet test can be a valuable tool to support diagnosis of dengue where laboratory tests are not available. However, the absence of a positive test should not be read as the absence of infection. In addition, the tourniquet test was demonstrated to be an indicator of dengue severity.

Prior to the Generics Act (Lei dos Genéricos), consumers had at their disposal two product purchase options in the private market, namely buying a reference drug and a similar one. Generic drugs are part of a public policy which was intended to broaden access to medication by the general population at more accessible costs, while maintaining the same quality as the reference drug, as ensured by bioequivalence tests from the national health surveillance agency ANVISA. Nevertheless, a question arises as to whether the potential consumer knows the difference between generic, similar and reference drugs, especially when taking into account the decision at the moment of purchase. In order to fulfill the proposed objective, a survey was conducted with 403 residents in Belo Horizonte, Brazil. The data gathered was tabulated and analyzed using factor analysis and crosstab. The results made it possible to infer that there is a strong predisposition among consumers to accept the suggestions of the pharmacists and/or salesman, and a significant portion of the population is confused at the moment of purchase.

    The assessment of data from a previous study of radon in indoor air of about 500 built 'slab-on-grade' dwellings in the metropolitan area of Belo Horizonte, RMBH, Brazil, showed some statistical correlations with lithologies and pedologies. Forty-five measurements of radon concentration in soil gases were performed at selected points according to population density, gamma radiation background and measurements results of the mentioned indoor radon concentrations study. This paper presents the distribution of radon concentration in soil gas in the same area, where it ranges from 7 - 93 kBq.m{sup -3}, highlighting the areas of high radon concentration in soil gas, which suggests occurrence of radon prone areas. In this regard, this work looking for correlation of radon concentrations in soil gas with lithologies and pedologies. The measurements were performed by using AlphaGUARD PQ2000 PRO SAPHYMO GmbH. The results of a radon survey in this areas has indicated that in the region radon prone areas may occur. Radon concentration measurements in soil gas are also being carried out to obtain higher statistical significance data for correlations and for comparison between equipment and probes from different systems suppliers like RTM 1688 of SARAD GmbH and RAD7 Electronic Radon Detector of DURRIDGE Company Inc. Thus, this research will represent the initial contribution to establish classification criteria, for radon in soil gas in a tropical climate similar to the Swedish criteria established by Akerblom.

  1. Evaluation of the waste profile from (medical) health services of Belo Horizonte concerned to the presence of radioactive wastes in the disposal system

    International Nuclear Information System (INIS)

    The medical procedures of diagnosis and treatment that use radiopharmaceuticals generate radioactive wastes that can, after reaching the release limit, follow the conventional ways of collection and disposal of the urban solid wastes. This research aims to detect radiometrically the presence of radioactive wastes in the health-care wastes at the final disposal. It is pointed out that the legal limit for the release of solid wastes established by Brazilian National Commission of Nuclear Energy (CNEN) is 7,5x104 Bq/kg (2 μCi/kg). Measurements in the material of the garbage trucks that make the special collect from Health Service installations are performed, at Belo Horizonte sanitary landfill, using a NaI scintillation counter. Values above the established limit were found in 60% of the cases. The spectral analysis of 6 samples showed the presence of 99mTc in 5 of them and 131I in one. These radionuclides are the most common radionuclides used in Nuclear Medicine. In conclusion there are radioactive wastes released together with the health service wastes, due to the disregard of the decay time until the legal limit is achieved. (author)

    Introduction: Asthma is a multifactorial disease and a serious public health problem. Environmental factors and poverty are the main determinants of this disease. Objective: To describe the spatial and temporal distribution of asthma-related hospitalizations and identify the areas with the highest prevalence of and vulnerability to severe asthma in a major Brazilian city. Methods: An ecological study of hospitalizations for asthma from 2002 to 2012, in children and adolescents under 15 years of age, living in Belo Horizonte, Southeast Brazil. All events were geocoded by residence address using Hospital Information System data. The socioeconomic vulnerability of residence address was ranked using the Health Vulnerability Index. Raster surfaces were generated and time-series plots were constructed to determine spatial and time trends in the frequency of asthma-related hospitalizations, respectively. Results: Asthma-related hospitalization rates were highest in children aged 0–4 years and in boys. There was a decreasing trend in the number of asthma-related hospitalizations across the study period. Approximately 48% of all hospitalizations were children living in health vulnerable areas. Seasonal trends showed a hospitalization peak in March, April, and May, coinciding with the post-rainy period. Conclusion: Our findings suggest that social and environmental factors may be determinants of disparities in severe asthma. PMID:27420078

    The aim of the present study was to analyze the spatial pattern of cases of maxillofacial injuries caused by interpersonal violence, based on the location of the victim’s residence, and to investigate the existence of conditions of socio-spatial vulnerability in these areas. This is a cross-sectional study, using the data of victims attended in three emergency hospitals in Belo Horizonte-Brazil between January 2008 and December 2010. Based on the process of spatial signature, the socio-spatial condition of the victims was identified according to data from census tracts. The spatial distribution trends of the addresses of victims were analyzed using Kernel maps and Ripley’s K function. Multicriteria analysis was used to analyze the territorial insertion of victims, using a combination of variables to obtain the degree of socio-spatial vulnerability. The residences of the victims were distributed in an aggregated manner in urban areas, with a confidence level of 99%. The highest densities were found in areas of unfavorable socioeconomic conditions and, to a lesser extent, areas with worse residential and neighborhood infrastructure. Spatial clusters of households formed in slums with a significant level of socio-spatial vulnerability. Explanations of the living conditions in segregated urban areas and analysis of the concentration of more vulnerable populations should be a priority in the development of public health and safety policies.

    Full Text Available The objective of this study was to identify tuberculosis risk factors and possible surrogate markers among human immunodeficiency virus (HIV-infected persons. A retrospective case-control study was carried out at the HIV outpatient clinic of the Universidade Federal de Minas Gerais in Belo Horizonte. We reviewed the demographic, social-economical and medical data of 477 HIV-infected individuals evaluated from 1985 to 1996. The variables were submitted to an univariate and stratified analysis. Aids related complex (ARC, past history of pneumonia, past history of hospitalization, CD4 count and no antiretroviral use were identified as possible effect modifiers and confounding variables, and were submitted to logistic regression analysis by the stepwise method. ARC had an odds ratio (OR of 3.5 (CI 95% - 1.2-10.8 for tuberculosis development. Past history of pneumonia (OR 1.7 - CI 95% 0.6-5.2 and the CD4 count (OR 0.4 - CI 0.2-1.2 had no statistical significance. These results show that ARC is an important clinical surrogate for tuberculosis in HIV-infected patients. Despite the need of confirmation in future studies, these results suggest that the ideal moment for tuberculosis chemoprophylaxis could be previous to the introduction of antiretroviral treatment or even just after the diagnosis of HIV infection.

    Full Text Available Abstract Obesity prevalence is rapidly increasing in developing countries. Existing research investigating social patterning of obesity and its risk factors in Latin American urban contexts has inconsistent findings. This study analyzed a multistage household survey in adults in Belo Horizonte, Minas Gerais State, Brazil. Marginal models were used to examine the association of education and household and neighborhood income with body mass index (BMI, obesity, physical inactivity, and low fruit and vegetable intake after adjusting for age and ethnicity and stratifying by sex. BMI and obesity were inversely associated with education in women. BMI was positively associated with household and neighborhood income in men. Additionally, physical inactivity and low fruit and vegetable intake were inversely associated with education and household income in both men and women, and physical inactivity was inversely associated with neighborhood income in men. Understanding the drivers of these patterns will allow for development of appropriate policy and interventions to reduce cardiovascular disease risk in large cities in Latin America.

    Identification of the zoonotic reservoir is important for leishmaniasis control program. A number of (wild) animal species may serve as reservoir hosts, including the opossum Didelphis marsupialis. A survey carried out in Didelphis specimens (n = 111) from the metropolitan region of Belo Horizonte, an important focus of human leishmaniasis in Brazil, is reported. All animals were serologically tested with indirect fluorescence antibody test (IFAT) and direct agglutination tests (DAT) based on L. (L.) donovani or L. (V.) braziliensis antigen. A sub-population (n = 20) was analyzed with polymerase chain reaction (PCR) for the presence of Leishmania-specific DNA. For species identification, PCR-positive samples were subjected to restriction enzyme fragment polymorphism (RFLP) analysis. Depending on the sero-diagnostic test employed, the sero-prevalence varied between 8.1% (9/111 animals positive with DAT test based on L. braziliensis antigen) and 21.6% (24/111 animals positive with IFAT). Five out of 20 samples analyzed with PCR tested positive for the presence of Leishmania-specific DNA. RFLP analysis revealed that two samples contained L. braziliensis complex DNA, one contained L. donovani complex DNA, and two samples could not be typed with the methodology used. These data suggest a potential role for the opossum as a reservoir host for zoonotic leishmaniasis in the region. PMID:17767408

    Full Text Available The presence of transmitted human immunodeficiency virus (HIV-1 drug-resistance (TDR at the time of antiretroviral therapy initiation is associated with failure to achieve viral load (VL suppression. Here, we report TDR surveillance in a specific population of men who have sex with men (MSM in Belo Horizonte, Brazil. In this study, the rate of TDR was evaluated in 64 HIV-infected individuals from a cohort of MSM between 1996-June 2012. Fifty-four percent had a documented recent HIV infection, with a seroconversion time of less than 12 months. The median CD4+T lymphocyte count and VL were 531 cells/mm3and 17,746 copies/mL, respectively. Considering the surveillance drug resistance mutation criteria, nine (14.1% patients presented TDR, of which three (4.7%, five (7.8% and four (6.2% had protease inhibitors, resistant against nucleos(tide transcriptase inhibitors and against non-nucleoside reverse-transcriptase inhibitors mutations, respectively. Two of the patients had multi-drug-resistant HIV-1. The most prevalent viral subtype was B (44, 68.8%, followed by subtype F (11, 17.2%. This study shows that TDR may vary according to the population studied and it may be higher in clusters of MSM.

    In Brazil, several recurring mutations in BRCA1 and BRCA2 and a TP53 mutation (R337H) have been reported in high risk breast cancer cases. We hypothesized that these recurring mutations may also be detected in the general population and ovarian cancer cases in the state of Minas Gerais. To test this notion, participants were recruited from the outpatient and the Gynecological clinic in the UFMG Medical Center in Belo Horizonte, Minas Gerais, Brazil. BRCA1 (c.68_69delAG, c.5266dupC, c.181T>G, c.4034delA, c.5123C>A), BRCA2 (c.5946delT, c.8537_8538delAG, 4936_4939delGAAA), the c.156_157insAlu* BRCA2 and the c.1010G>A *TP53 mutation were genotyped using validated techniques. Overall, 513 cancer free participants (273 men) (mean age 47.7 ± 15.1 years) and 103 ovarian cancer cases (mean age at diagnosis 58.7 ± 9.6 years) were studied. None of the participants were found to carry any of the genotyped mutations. We conclude that the recurring mutations in BRCA1, BRCA2 and TP53 cannot be detected in the general population or consecutive ovarian cancer cases in this geographical region in Brazil.

    Full Text Available ResumoMesmo após a publicação da Lei 8213, em 1991, que institui cotas para contratação de pessoas com deficiência, a inclusão delas no trabalho ainda é um desafio para a sociedade brasileira. Para tentar entender as principais barreiras que impedem este processo foi realizada uma pesquisa qualitativa no município de Belo Horizonte. Este estudo contou com entrevistas com atores importantes no processo de inclusão; e grupos focais com pessoas com deficiência e seus familiares. As principais barreiras encontradas foram: preconceito e discriminação; a relação familiar; o Benefício da Prestação Continuada; a baixa qualificação das pessoas com deficiência; a falta de acessibilidade; e o despreparo das empresas. Conclui-se que a elaboração de leis não é suficiente para a inclusão no mercado de trabalho e que os governos devem implementar políticas públicas que auxiliem este processo.

    The scope of this study is to evaluate the condition of household food and nutrition (in)security (IAN) of the users of low-budget restaurants in Belo Horizonte (BH). This is an analytical cross-sectional study carried out on all low-budget restaurants and cafeteria in BH with a sample of 1613 users. The IAN was assessed using the Brazilian Food Insecurity Scale and cross-checked with the socioeconomic profile of the users. The Chisquare and Mann-Whitney tests were applied. All p-value budget restaurants are those with a lower socioeconomic level and per capita income class and those with a large number of residents in the household. Also affected are those who admit to having different kinds of wants and needs, and those for whom price and living alone are the main reasons for frequenting low-budget restaurants. The factors affecting the IAN are varied and multifactorial, thus representing a major challenge for public policy makers and for those who live directly with these dietary restrictions. The low-budget restaurants serve as a strategy for promoting healthy eating habits.

    Phlebotomine sand flies are distributed across nearly all faunal regions of the world, represented by over 800 species, of which many are important vectors of human pathogens. Brazil is currently faced with the expansion and urbanization of leishmaniases, with an increase in the numbers of human cases and seropositive dogs in various medium-sized to large cities. The objective of the current study was to survey the phlebotomine sand fly species in an area endemic for American cutaneous leishmaniasis (ACL) and American visceral leishmaniasis (AVL), i.e., the municipal district of Santa Luzia, lying within the metropolitan region of Belo Horizonte in the Brazilian State of Minas Gerais. Sand flies were collected monthly in 2004-2005 using modified Falcão light traps hung in the peridomiciles of houses and surrounding wooded areas in the district of Baronesa. A total of 1,552 sand flies belonging to seven species was collected, and an interesting pattern of the distribution of the most abundant species relative to the sampling locality was revealed. In the wooded areas Lutzomyia whitmani (Antunes & Coutinho) predominated, whereas in the urban area Lutzomyia longipalpis (Lutz & Neiva) was the most abundant species. These results indicate two possible epidemiological patterns of Leishmania transmission in Santa Luzia: one for American cutaneous leishmaniasis associated predominantly with wooded areas, and another for AVL, with transmission principally occurring around human habitations.

Total PHC score was 0.75 (good). The dimensions first contact (0.95), longitudinality (0.83), comprehensiveness (0.83), and coordination (0.78) performed the best. Family approach, community orientation, and access received the lowest scores (0.68, 0.56, and 0.45, respectively). Better PHC performance was associated with the following factors (p family health teams (PR = 1.44), a physician on duty for more than 30 hours per week (PR = 1.42), and presence of four or more teams per primary care unit (PR = 1.09). The results show the importance of structural and organizational factors for PHC performance and suggest that permanent evaluation can identify aspects that require quality improvement.

This was a cross-sectional study of 310 patients enrolled in two public health centers in Belo Horizonte, Minas Gerais State, Brazil. Delayed ART initiation was defined as starting treatment with a CD4 count lower than 200 cells/mm³ or clinical symptoms of severe immunodepression at the time of first antiretroviral prescription. The majority of participants were males (63.9%, had no health insurance (76.1%, and started ART less than 120 days after the first medical visit (75.2%. The proportion of delayed ART initiation was 68.4%. Unemployment, referral by a health professional for HIV testing, fewer than two medical visits in the six months prior to ART initiation, and time between first medical visit and ART initiation less than 120 days were independently associated with the outcome. Our results suggest that every patient 13 to 64 years of age should be offered HIV testing, which could increase the rate of early HIV diagnosis, and thus patients that tested positive could benefit from timely follow-up and antiretroviral therapy.

MÉTODOS: foram selecionados dos arquivos médicos todos os casos de câncer de mama diagnosticados entre os anos de 1985 e 2000, encontrando-se 179 casos com diagnóstico de CDIS. Fez-se revisão anátomo-patológica das lâminas e obtiveram-se dados clínicos completos, mamografias e informações sobre tratamento em 85 casos. RESULTADOS: a maioria dos casos eram assintomáticos e os diagnósticos foram feitos pela mamografia (68,2%, sendo as microcalcificações a alteração radiológica mais freqüente. Houve aumento progressivo no diagnóstico de CDIS ao longo dos anos simultâneo à introdução do exame periódico mamográfico. Houve concordância entre o diagnóstico inicial e após a revisão histopatológica em 72,9% dos casos. Em três casos, o diagnóstico original de CDIS não foi confirmado pela revisão, tratando-se de hiperplasias com atipias. O achado de microcalcificações radiológicas foi confirmado no estudo histopatológico em 95,6%. A metade dos pacientes foi submetida à mastectomia. Nos casos submetidos à linfadenectomia axilar, todos os linfonodos dissecados foram negativos para metástases. CONCLUSÕES: os dados encontrados estão de acordo com a literatura, que mostra um aumento do diagnóstico do CDIS a partir de 1990. Houve importante variação interobservador entre os diagnósticos anátomo-patológicos iniciais e os da revisão, sendo que os diagnósticos iniciais tendiam para malignidade. Houve grande número de tratamentos mais radicais como a mastectomia e esvaziamentos axilares, que provavelmente, com os conhecimentos atuais, seriam substituídos por tratamentos conservadores e biópsia do linfonodo sentinela.PURPOSE: to evaluate the clinical, radiological therapeutic and

    Full Text Available This survey was conducted in 2009 to identify the main factors contributing to occupational stress of health workers in three adult ICUs of a public municipal hospital in Belo Horizonte. For this purpose a structured questionnaire was used with 28 questions taken from a version of the Job Stress Scale of the Demand-Control model of Karasek, abridged and adapted to Portuguese. This is a quantitative case study of a descriptive nature. One may consider that the objectives presented were achieved and that results indicated high levels of demand, control and social support. Correlation between the constructs showed no statistically significant differences for ICUs under study. Workers experience the work process actively and even when demands are excessive, they generate less harmful impacts because the worker can develop strategies to deal with difficulties of planning working hours according to his biological rhythms. The need to conduct research in the occupational health area is emphasized to develop and orient the hospital sectors together with the human resources sector to offer improved conditions for obtaining occupational health quality for these professionals.Esta investigación fue realizada en 2009 y tuvo como objetivo identificar los principales factores que contribuyen para el estrés ocupacional de los trabajadores de la salud en los tres CTIs adulto de un hospital público municipal de Belo Horizonte.

    Full Text Available OBJETIVO: Analisar a evolução da mortalidade, por idade e sexo, segundo as causas de morte, nas regiões metropolitanas de Belo Horizonte (RMBH e Salvador (RMS, entre 1985 e 1995. MÉTODOS: Os dados utilizados foram provenientes do Registro Civil, fornecidos pelo SIM (Sistema de Informação sobre Mortalidade do Ministério da Saúde. As causas de morte foram classificadas em evitáveis e não evitáveis. Aplicou-se o método de decomposição de Pollard para analisar a contribuição, na evolução dos ganhos de esperança de vida ao nascer, dos grupos de causas que tiveram um aumento da sua participação relativa na estrutura da mortalidade. RESULTADOS: O processo de declínio da mortalidade, em curso nas regiões metropolitanas estudadas, vem sofrendo mudanças nas últimas décadas com uma tendência à redução dos diferenciais existentes. No seu conjunto, as causas evitáveis reduziram seu peso relativo em ambas as regiões: na RMBH, de 36,5%, em 1985, para 30,6%, em 1995, entre os homens, e de 34,9%, em 1985, para 28%, em 1995, entre as mulheres. Na RMS, observou-se uma redução maior da participação relativa para as mulheres: de 35,4%, em 1985, para 25,9%, em 1995. Para os homens, essa participação passou de 44% do total, em 1985, para 39,7%, em 1995. CONCLUSÕES: Ainda persiste uma estrutura de causas de morte que pode estar indicando que, nas regiões estudadas, os progressos nos níveis de mortalidade não estão atingindo as populações menos favorecidas na intensidade e velocidade esperadas.OBJECTIVE: To analyze differential changes of rates and stratification of mortality by gender and causes of death in the metropolitan area of Belo Horizonte (RMBH and Salvador (RMS between 1985 and 1995.

    Full Text Available Em um contexto social complexo e globalizado e sob um regime constitucional democrático, o Poder Público tem buscado novas formas de participação dos cidadãos nos negócios públicos. A participação direta, mediante o acesso da sociedade ao processo de decisão sobre políticas públicas, tem constituído importante instrumento para a concretização, no Brasil, de uma democracia que alia instrumentos representativos e diretos. Entre as principais experiências verificadas no país encontra-se a adoção, pela Administração Pública, do Orçamento Participativo, estratégia que permite ao cidadão definir, em certa medida, a alocação de recursos públicos em um dado período. Este trabalho parte dessas premissas e avalia a implementação e execução do Orçamento Participativo Digital – OPD - no Município de Belo Horizonte no ano de 2006. No estudo realizado verificou-se que o OPD representa um aprofundamento, em qualidade e quantidade, do Orçamento Participativo, pois tanto expande a participação quanto resguarda mais a autonomia da vontade do eleitor. Apesar dos problemas apresentados, constatou-se que o OPD constitui um passo importante para a ampliação da democracia participativa

    Full Text Available O trabalho pretende identificar os diferenciais intra-urbanos em Belo Horizonte, Brasil, estudando os coeficientes de mortalidade infantil (CMI nas áreas do município e avaliando sua evolução no período 1994/1996. A análise das condições de saúde referenciadas territorialmente constitui importante campo de estudo para evidenciar desigualdades regionais e intra-urbanas. Para os anos de 1994 e 1996, foram utilizados os dados do SINASC e SIM, além de mapas temáticos com o recorte geográfico da "área de abrangência" dos Centros de Saúde. Aplicou-se o método Bayesiano empírico para o cálculo dos CMI dessas áreas, visando corrigir possíveis flutuações aleatórias decorrentes de números pequenos e instáveis. Em todo o período, houve redução do CMI global do município em 24,4%, assim como do CMI nas áreas de abrangência. Em 1994, oito áreas apresentaram CMI acima de 50/1.000 e, em 1996, nenhuma área foi observada com esse coeficiente; em 1994, vinte e nove áreas mostraram CMI entre 35 a 50/1.000, caindo para quatro áreas em 1996; neste ano, registrou-se, em relação a 1994, maior número de áreas com CMI abaixo de 35/1.000. Em 1996 existiu maior homogeneidade na distribuição dos CMI, reduzindo-se as desigualdades intra-urbanas.

    The radon concentration in soil gas is directly dependent on the geological characteristics of the area, such as lithology, pedology and on geochemicals, physicals and mineralogicals parameters of the soil. This paper looks for correlations between radon concentrations in soil gas and its soil permeability, 238U, 232Th and 226Ra contents in the soil groups classified by pedologies of Metropolitan Region of Belo Horizonte (RMBH), Minas Gerais, Brazil. The soil gas radon concentrations were determined by using an AlphaGUARD® monitor at about 150 measurement points. In soil samples of the same measurement points, the concentrations of 226Ra were determined by gamma spectrometry (HPGe), and 238U and 232Th by ICP-MS. The soil permeabilities were determined by using the RADON-JOK® permeameter. The mean concentrations of radon in soil gas ranged from 13.6±3.0 kBq m-3 for Litholic Neosols until 60.6±8.7 kBq m-3 for Perferric Red Latosols. The mean of 226Ra activity concentrations presented variation of 12.4±2.5 Bq kg-1 for Litholic Neosols until 50.3±13 Bq kg-1 for Perferric Red Latosols. Approximately 40% of the soils presented high permeability. The areas of different pedologies were classified by Soil Radon Index (SRI), determined by the soil gas radon concentration and permeability. Approximately 53% of the Perferric Red Latosols measurement site could be classified as "High Risk" (Swedish criteria). The preliminary results may indicate an influence of iron formations present very close to the Perferric Red Latosols in the retention of uranium minerals, and hence an increase in the concentration of radon and radium, whereas the series are in equilibrium in the environment.

    Full Text Available O objetivo deste trabalho foi determinar a prevalência do tabagismo e verificar os fatores associados a este hábito entre idosos (> 60 anos. O estudo foi conduzido na Região Metropolitana de Belo Horizonte e na Cidade de Bambuí, ambas localizadas em Minas Gerais, Brasil. Foram selecionados 1.774 idosos na Região Metropolitana e 1.742 em Bambuí. Na Região Metropolitana, a prevalência de tabagismo atual e passado foi de 19,6% e 39,2% entre os homens, e 8,1% e 14,1% entre as mulheres, respectivamente. Em Bambuí, os dados correspondentes foram 31,4% e 40,2% entre os homens, e 10,3% e 11,2% entre as mulheres, respectivamente. Na Região Metropolitana, os indicadores de pior condição de saúde e pior capacidade funcional apresentaram associações significantes com o tabagismo passado, mas estas associações não foram observadas em Bambuí. Entre os fumantes atuais, as associações pesquisadas não foram consistentes. Estes resultados mostram a grande heterogeneidade dos fatores associados ao tabagismo, como observado em países desenvolvidos. As estratégias para a redução do tabagismo nessa população devem considerar esta ausência de associação entre sinais e sintomas e o hábito de fumar.

Foi constatado um elevado número de profissionais médicos que apresentam mais de uma forma de remuneração em todas as situações de trabalho. Os três atores envolvidos acreditam que a melhor forma de remuneração é aquela que considere alguma medida de resultado, visando maiores qualidade e resultado. A forma de remuneração por produção foi escolhido pelos médicos como a mais justa e satisfatória. O interesse pelo tema, demonstrado pelos profissionais, aliado à relevância do mesmo como um dos instrumentos de aperfeiçoamento gerencial, justifica mais estudos na área.

O consumo, nesse sentido, é visto como o elo entre as dimensões "população" e "geração de resíduos". A fonte de dados sobre a geração de resíduos sólidos é a Superintendência de Limpeza Urbana (SLU, responsável pela coleta e sistematização das informações em uma malha cartográfica digital. Tal representação espacial das informações permitiu concatená-las com os dados da malha digital das Áreas de Ponderação do Instituto Brasileiro de Geografia e Estatística (IBGE, referentes ao Censo Demográfico 2000. Métodos estatísticos multivariados foram empregados para investigar as associações entre variáveis populacionais e a produção de resíduos. O trabalho se destaca no cenário dos estudos de população no Brasil pelo uso inédito de informações produzidas sobre resíduos sólidos urbanos e a interação de sua produção com aspectos socioeconômicos e demográficos. Os resultados indicam que a concentração de domicílios unipessoais, população e chefes com 60 anos e mais, e idade média elevada, algo como um "perfil demográfico urbano-contemporâneo", surge recorrentemente como aspecto demográfico central na diferenciação de áreas de maior geração per capita.

    Full Text Available There is a theoretical need to contribute to the recognition of the statute of the urbanization of Belo Horizonte, thinking about it from its metropolitan outskirts. These outskirts, whose contradictions have materialized in the struggles for the achievements of urbanization, have proliferated in the wake of urbanization which was transformed into a business field. The lack of resolution of these contradictions makes others explicit: the update of the institutionalized forms of what has been called well-being and fulfillment of life has meant a growing dissatisfaction with everyday life. The obfuscation of the lens, which allow us to question this everyday life, grows due to an unprecedented material abundance.

    Full Text Available The serological profile of seropositive dogs according to anti-Leptospira agglutinins was checked in Belo Horizonte including variables such as race, sex, age and whether the dog had an owner or not. The dogs were captured by the Zoonosis Control Center in nine neighborhoods around the city and were separated in two categories - with owners or captured on the streets. The prevalence of anti-Leptospira agglutinins was evaluated in 3,417 blood samples using the microscopic agglutination test (MAT from September 2001 to September 2002. It was found that 13.1% of the dogs had seropositive results with the most reactive serovars being Canicola (7.0%, Ballum (6.1%, Pyrogenes (3.2% and Icterohaemorrhagiae (2.9%. The prevalence of other serovars was less than 1.0%. Greater prevalence was found in male, crossbred dogs, without owners. There were no significant results due to age in 95% (P=0.808 of the cases. According to the results, more research should be done in order to isolate and classify the serovars in positive dogs, especially Ballum and Pyrogenes, which will suggest their inclusion in the commercial vaccines against leptospira used in dogs in this city.

    Abordando o turnover – tema inserido no campo de estudos denominado Comportamento Organizacional -, este trabalho tem como objetivo investigar as intenções de turnover entre os vendedores e gerentes de duas redes de lojas da cidade de Belo Horizonte. Pretende-se, também, fornecer subsídios para o início de uma reflexão profunda sobre o tema e um embasamento para futuras pesquisas, focando o turnover na área do comércio varejista. Utilizou-se a pesquisa-diagnóstico, exploratória, de cunho estritamente qualitativo. O interesse pela pesquisa do tema no Brasil ocorre em função da constatação que, não obstante a sua relevância para a competitividade das organizações, o assunto não vem recebendo aqui, ao contrário da Europa e Estados Unidos, a mínima atenção. Este estudo é o início de uma linha de pesquisa que objetiva entender como se desenvolve o fenômeno do turnover no Brasil, quais os seus antecedentes, correlatos e conseqüentes. Contudo, a principal conclusão deste estudo é que os determinantes das intenções de turnover são de natureza subjetiva, mais especificamente as percepções das oportunidades do mercado de trabalho e se as percepções ligadas ao cargo têm um importante papel nas explicações desse fenômeno

MÉTODOS: Estudo realizado em Belo Horizonte, estado de Minas Gerais, de março de 2004 a maio de 2005. Foram avaliadas 408 crianças pré-escolares encaminhadas da atenção primária para a secundária do setor de otorrinolaringologia com otite, faringoamigdalite, rinossinusite, rinite alérgica e hipertrofia de amígdala/adenóide. As variáveis analisadas foram: concordância dos diagnósticos na atenção primária e secundária, tempo de espera pela consulta, acompanhamento e especialista (médico de família ou pediatra que examinou a criança na atenção primária. A concordância dos diagnósticos foi avaliada pela análise estatística de kappa. RESULTADOS: Os pacientes tinham em média cinco anos de idade, dos quais 214 (52,5% eram meninos, o tempo médio de espera pela consulta foi de 3,7 meses. Os diagnósticos na atenção primária e secundária foram, respectivamente: otite (44%, 49%, hipertrofia de amígdala/adenóide (22%, 33%, faringoamigdalite (18%, 23%, rinossunusite (13%, 21%, rinite alérgica (3%, 33%.

Os diagnósticos na atenção primária para encaminhamento à secundária, definidos pelo médico de família ou pelo pediatra que avaliou a criança foram concordantes. CONCLUSÕES: A inadequação dos encaminhamentos da atenção primária para a secundária em otorrinolaringologia foi expressa pelo longo tempo de espera pela consulta e pela baixa concordância de diagnósticos firmados entre os níveis de atenção para os mesmos pacientes avaliados. A atenção primária poderia se tornar mais eficiente se os profissionais fossem mais bem capacitados em otorrinolaringologia

Na análise foram utilizados dados provenientes de dois inquéritos, cuja amostra total foi de 648 jovens do sexo feminino entre 15 e 24 anos de idade, 292 residentes em bairros de classe média e 356 em favelas situados na região centro-sul da cidade de Belo Horizonte, Brasil. Nos resultados, encontrou-se uma prevalência bruta de 27,3% de gravidez até os 19 anos entre as jovens residentes em favelas e de 1,7% entre as moradoras em bairros da região centro-sul de Belo Horizonte. Os dados apontam para uma relação direta entre a gravidez na adolescência com o controle e a violência por parte do parceiro. Entre aquelas residentes em favelas, 48% das que declararam ter sofrido violência física por parte de um parceiro e 58% das que declararam ter sofrido violência sexual haviam engravidado ao menos uma vez antes dos 19 anos.

The qualitative method that was used applied activity observation techniques combined with simultaneous and outside work interviews. Narrative analysis was used based on categories of interest defined to answer the study hypothesis. The results show that there is a direct influence of families and the community on the performance of the activities and that the groups mobilize strategies to achieve their aims. This behavior expresses that the family and society accept and participate in the organization of children's work on the street. However, exposure to violence is not diminished by parents' participation nor by the constitution of a supposed solidarity network. Educational possibilities are not anticipated due to the work conditions, which are incompatible with the subjects' age.

In order to accomplish this, we took into account Paiva’s competence model (Paiva, 2007. The field research was characterized as a descriptive case study, with a qualitative approach. The data were collected through documentation survey and analysis and by interviews. The subjects were chosen using accessibility and convenience criteria. The data collected were organized, processed and analyzed by the technique of content analysis. Subsequently, the demographic and functional data of respondents were presented. For most of the inverviewees, the notion of competence is linked to action; they are aware that managers occupy a middle ground in the organizational hierarchy and that they work in an environment known by ambiguity, contradictions and demands. So, to be competent managers, interviewees attested the need for academic training, while considering the importance of experience. This study suggests the importance of informal learning in the managers’ competences training and development, especially through the figure of the "model manager"; in other words, the one that is considered the mirror to the other members of the sales team. Finally, limitations of this study and suggestions for further research were pointed out.

    Full Text Available INTRODUTION: A major concern with the visceral leishmaniasis (VL is its high lethality rate, even with proper treatment. Low age, prior malnutrition, disease duration prior to diagnosis, severe anemia, fever for more than 60 days, diarrhea and jaundice are known poor prognostic factors. The goals of this study are to describe the clinical and laboratory characteristics of VL among children under 12 years of age and to identify the factors associated with VL poor outcome. METHODS: Two hundred and fifty children under 12 years of age with confirmed VL admitted to Hospital João Paulo II (FHEMIG, Belo Horizonte, Brazil, between January 2001 and December 2005 were evaluated retrospectively. The primary outcome was the poor clinical evolution: sepsis, and/or pneumonia, and/or urinary tract infection, and/or of bleeding (expect epistaxis, and/or severe neutropenia (neutrophil < 500 cells/mm3. Odds ratio (crude and adjusted and its 95% confidence interval for each variable were calculated. Values less than 0.05 were considered significant. RESULTS: Average age was 3.3 years (3.6 months-11.6 years, 71.2% were younger than 5 years and 47.2% lived in Metropolitan Area of Belo Horizonte. The mean fatality rate was 3.6%. Sixty-six (26.4% patients presented poor evolution. After a multivariate analysis, age <18 months, abnormal respiratory physical examination on hospital admission, and platelets <85,000/mm3 remained associated with increased chance of poor evolution. CONCLUSIONS: The results suggest that patients aged between 12 and 18 months, with platelet counts bellow 85,000/mm3, and respiratory abnormalities at admission should be considered potentially severe.

    Full Text Available Neste trabalho, investiga-se como desigualdades de classe e de gênero atuam no sentido de reduzir o grau de autonomia de adolescentes (15 a 19 anos e mulheres jovens (20 a 24 anos, influenciando seu comportamento sexual e reprodutivo, especificamente na experiência da gravidez na adolescência. Na análise foram utilizados dados provenientes de dois inquéritos, cuja amostra total foi de 648 jovens do sexo feminino entre 15 e 24 anos de idade, 292 residentes em bairros de classe média e 356 em favelas situados na região centro-sul da cidade de Belo Horizonte, Brasil. Nos resultados, encontrou-se uma prevalência bruta de 27,3% de gravidez até os 19 anos entre as jovens residentes em favelas e de 1,7% entre as moradoras em bairros da região centro-sul de Belo Horizonte. Os dados apontam para uma relação direta entre a gravidez na adolescência com o controle e a violência por parte do parceiro. Entre aquelas residentes em favelas, 48% das que declararam ter sofrido violência física por parte de um parceiro e 58% das que declararam ter sofrido violência sexual haviam engravidado ao menos uma vez antes dos 19 anos. A associação da violência de gênero com a gravidez na adolescência se manteve presente mesmo quando controlada por classe social, ainda que seu peso fosse muito mais pronunciado entre as jovens de baixa renda. Esses resultados reforçam a importância de se aprofundar a compreensão acerca do impacto das desigualdades de classe e gênero no comportamento sexual e reprodutivo de adolescentes e mulheres jovens.

Foram entrevistados, também, os representantes das corporações médica e empresarial. Na análise de dados, utilizando-se conceitos adaptados da Organização Internacional do Trabalho (OIT, encontrou-se o Sistema de Remuneração por Resultado, exclusivo dos hospitais privados, e o Sistema de Remuneração por Tempo, prevalente nos hospitais públicos. Foi constatado um elevado número de profissionais médicos que apresentam mais de uma forma de remuneração em todas as situações de trabalho. Os três atores envolvidos acreditam que a melhor forma de remuneração é aquela que considere alguma medida de resultado, visando maiores qualidade e resultado. A forma de remuneração por produção foi escolhido pelos médicos como a mais justa e satisfatória. O interesse pelo tema, demonstrado pelos profissionais, aliado à relevância do mesmo como um dos instrumentos de aperfeiçoamento gerencial, justifica mais estudos na área.A descriptive analysis of systems and forms of payment for medical labor was carried out based on an intentional sample of hospitals, according to preestablished criteria.

A commercially available immunoenzymatic assay (ProSpecT Giardia Microplate Assay, Alexon, Inc., BIOBRÁS to detect G. lamblia specific coproantigen was evaluated for the first time in Brazil. A total of 90 specimens were tested. Each specimen was first tested as unpreserved stool, and then it was preserved in 10% Formalin to be tested 2 months later. The assay was able to identify all the 30 positive patients (sensitivity = 100.0% by visual or spectrophotometric examination in the unpreserved specimens and was negative in 57 of the 60 patients without G. lamblia (specificity = 95.0%. The assay identified 27 of the 30 positive patients (sensitivity = 90.0% and was negative in 59 of the 60 negatives (specificity = 98.3% in the preserved stools according to both readings. A marked difference was observed in the optical densities in both groups, preserved and unpreserved stools, when the G. lamblia-positive specimens were compared to the negative or positive for other intestinal parasites than G. lamblia. The assay seems a good alternative for giardiasis diagnosis, especially when the fecal examination was repeatedly negative and the patient presents giardiasislike symptoms.O diagnóstico da giardíase através da pesquisa de trofozoítos ou cistos do parasita nas fezes apresenta uma elevada percentagem de resultados falso-negativos.

Frankfurters were produced at small, medium and large plants, according to the target market (local, regional and national. Determination of hydroxyproline was made by colorimetric method. The results showed that the frankfurters had different standards in the manufacturing, since the collagen content was statistically different. Samples from the medium size industry presented the lowest collagen content (0.45%, followed by samples from the large size plant (0.64%. Frankfurters from the small size industry had the highest collagen content (0.89%. These data showed that this analytical procedure can be used for quality classification of frankfurter based on collagen content.

    Full Text Available The purpose of this study was to analyze the development of strategies in nonprofit organizations located in the city of Belo Horizonte. Given that nonprofit organizations have in their daily lives the need to promote management actions consistent with a given rationality, which is not necessarily the same for public and private institutions, an appropriate management to their specificities – substantive and non-instrumental – became a major challenge. The study consisted of a descriptive and qualitative research in which were used documents and semi-structured interviews with representatives of 22 organizations, analyzed in accordance with the assumptions of content analysis were used. The axis of the main methodological data analysis was content analysis. The survey results showed that the perspective of the strategy in nonprofit organizations is becoming more complex, without losing the procedural characteristics of fundraising, mobilization and legality. This characteristic reinforces the need to invest in nondeterministic studies such as strategy as a social practice, especially in this field, where the construction of prescriptive models seems inconsistent with the presented reality, since it was clear that the strategy making in these organizations takes place through social and political constructions.

Apesar dessas infecções poderem se manifestar após a alta, no Brasil, a maioria dos serviços não faz vigilância pós-alta. Para avaliar a importância dessa vigilância e o perfil das infecções em crianças e adolescentes, acompanhou-se uma coorte de 730 pacientes cirúrgicos de um hospital universitário de Belo Horizonte, Minas Gerais, Brasil, de 1999 a 2001.

Surgical site infections are the most frequent, and can manifest after hospital discharge. In Brazil, the majority of clinical services do not maintain infection surveillance after discharge. In order to evaluate the importance of such surveillance and the profile of these post-discharge infections, a cohort of 730 child and adolescent surgical patients was followed in a teaching hospital, from 1999 to 2001. The accumulated incidence was calculated. Student's t test was used to compare mean values and the Kaplan-Meier method to analyze the period until infection, using a p value of < 0.05. A total of 87 surgical site infections were diagnosed, 37% of which after discharge. The overall surgical infection rate was 11.9%; without outpatient follow-up, the rate would have been 7.5%. Post-charge infections were diagnosed after a mean of 11.3 ± 6.4 days, and in these patients the preoperative and postoperative hospital stays were significantly lower than in the group with in-hospital infections. The study indicates the importance of post-discharge surveillance in determining the real incidence of surgical site infections.

    Full Text Available A indústria de software tem apresentado crescimento vigoroso nos últimos anos, não só em termos mundiais, como também no Brasil. O segmento é composto basicamente por empresas de pequeno porte, com utilização intensiva de mão de obra especializada. No entanto, estudos indicam que o setor pouco se preocupa com a qualificação de funcionários, talvez porque, normalmente, a demanda supere a oferta, o que relega a um plano secundário as preocupações com a gestão de pessoas, ficando as atenções voltadas para o desenvolvimento e a formatação do serviço propriamente dito. Segundo os modelos teóricos, a participação dos funcionários é de vital importância para o fornecimento de um serviço de qualidade, podendo acarretar a satisfação dos clientes, sua lealdade e, consequentemente, incrementar a rentabilidade da organização. A satisfação dos funcionários pode ser alcançada pela introdução de práticas adequadas de gerenciamento de recursos humanos, incluindo boa comunicação, treinamento e desenvolvimento, trabalho em equipe, incentivo à participação e poder de decisão. Diversos modelos foram propostos para avaliar a satisfação dos clientes, a qual é fruto da qualidade percebida do serviço, de suas expectativas e do valor percebido, de acordo com um dos modelos em questão. Alguns estudos relatam a existência de relação positiva e significativa entre satisfação de clientes e de funcionários. Nesse contexto, procurou-se avaliar qual o impacto da satisfação dos funcionários diretamente sobre a satisfação dos clientes, com base em um modelo teórico que integrasse práticas de Recursos Humanos e antecedentes da satisfação dos clientes. Por meio de pesquisa quantitativa, foram entrevistados clientes e funcionários de 50 empresas da indústria de software de Belo Horizonte (Minas Gerais, Brasil, totalizando uma amostra válida de 147 respondentes para cada grupo.

Among patients, 229 (75.8% were female and 155 (51.3% were Caucasian; the mean age was 50.3 ± 12.8 years, and the mean disease duration was 9.9 ± 8.7 years. Among them 214 patients (70.9% received adalimumab, 72 (23.8% etanercept, and 16 (5.3% infliximab. Mean Health Assessment Questionnaire-Disability Index (HAQ-DI was 1.37 ± 0.67 for all participants. Poor functional response was associated with female gender, married patients and with a score of < 0.6 on the EuroQoL-5 dimensions (EQ-5D. Significant correlation was found between the HAQ-DI values, disease activity and quality of life (QOL. The results obtained in this study contribute to a better understanding of the clinical and demographic characteristics of patients with rheumatic diseases at the beginning of anti-TNF-agent treatment by SUS. Furthermore, our findings are consistent with another Brazilian and foreign cross-sectional investigations. This knowledge can be of great importance for further studies evaluating the effectiveness of biological agents, as well as, to contribute to improve the well-being of the patients with rheumatic diseases.

    Full Text Available Apesar da maioria dos estudos etnobotânicos serem focados em populações tradicionais, as populações de áreas urbanas também vêm sendo investigadas. O presente trabalho realizou um levantamento etnobotânico de plantas medicinais nos quintais de um bairro urbano, próximo à zona rural, no município de Ituiutaba, MG, visando resgatar e identificar o conhecimento local a respeito das plantas medicinais. Para isso, 40 residências foram visitadas e os dados coletados por meio de entrevistas semi-estruturadas realizadas com os moradores. Foram encontradas 72 espécies de plantas medicinais, distribuídas em 33 famílias botânicas, destacando-se Asteraceae e Lamiaceae pelo número de espécies. As cinco espécies mais citadas pelos moradores foram: Mentha sp., Cymbopogon citratus, Sedum dendroideum, Plectranthus barbatus, e Rosmarinus officinalis. O hábito herbáceo foi predominante, e a parte da planta mais usada foi a folha, enquanto a decocção foi o modo de preparo mais frequente. Por mais que existam particularidades entre os diversos costumes e culturas das comunidades locais no Brasil, foi observada similaridade entre os resultados encontrados neste trabalho com outros levantamentos realizados, reforçando a importância da preservação e divulgação do conhecimento popular.

    Full Text Available Em um contexto social complexo e globalizado e sob um regime constitucional democrático, o Poder Público tem buscado novas formas de participação dos cidadãos nos negócios públicos. A participação direta, mediante o acesso da sociedade ao processo de decisão sobre políticas públicas, tem constituído importante instrumento para a concretização, no Brasil, de uma democracia que alia instrumentos representativos e diretos. Entre as principais experiências verificadas no país encontra-se a adoção, pela Administração Pública, do Orçamento Participativo, estratégia que permite ao cidadão definir, em certa medida, a alocação de recursos públicos em um dado período. Este trabalho parte dessas premissas e avalia a implementação e execução do Orçamento Participativo Digital – OPD - no Município de Belo Horizonte no ano de 2006. No estudo realizado verificou-se que o OPD representa um aprofundamento, em qualidade e quantidade, do Orçamento Participativo, pois tanto expande a participação quanto resguarda mais a autonomia da vontade do eleitor. Apesar dos problemas apresentados, constatou-se que o OPD constitui um passo importante para a ampliação da democracia participativa.Palavras-chave: orçamento participativo; administração pública

Este artigo, descreve a experiência da “Cidade dos Meninos” e de seu idealizador, apoiando-se em teorias recentes sobre empreendedorismo social. Atenção especial é dada à definição de empreendedor social catalítico (WADDOCK; POST, 1991, relacionando a atuação da liderança da Cidade dos Meninos a esse perfil. Uma das possíveis conclusões é que, em países em desenvolvimento como o Brasil, o empreendedor social catalítico não pode exercer apenas a função de criador e implementador de políticas, face a dimensão da carência e do problema com o qual ele se confronta, envolvendo-se então na ação direta

    The 'Culture and Memory of the Sto. Antonio do Morro Grande Quilombola Community' Program was included in the environmental licensing process of the Rio de Janeiro-Minas Gerais gas pipeline ('GASBEL II'), as requested by the Palmares Cultural Foundation (Fundacao Cultural Palmares), which stipulates the elaboration and implementation of this program as a condition for obtaining the installation license. To develop the program and submit it to this institution, we used methodological procedures in the form of an anthropological social research, such as: interviews with the community's older or most active residents, and a preliminary recognition of the territory and the local culture; all in order to learn more about the community's history and current needs and to identify the remaining 'quilombolas' still living in the community. Analyzing the information raised the need for guided actions designed to rescue the community's cultural memory as an ethnic group and to contribute to its process of affirmation as a Traditional Rural 'Quilombola' Community. This led to the creation of the proposed 'Culture and Memory of the Sto. Antonio do Morro Grande Quilombola Community' Program, currently being developed for the Quilombola Community located in Ressaquinha, in the State of Minas Gerais. (author)

    Full Text Available CONTEXT: Patients with autoimmune rheumatologic conditions and celiac disease tend to have a variety of autoantibodies, many of which have no clear pathogenic role. The literature contains frequent reports of celiac disease being more prevalent in patients with rheumatologic diseases, although this remains controversial. OBJECTIVES: To investigate the prevalence of positive serum tests for celiac disease, particularly IgA and IgG antigliadin (AGA antibodies and IgA antiendomysium antibodies (EmA in patients with autoimmune rheumatologic diseases. A second aim was to correlate positive serum tests with prednisone and immunosuppressant medication. METHODS: A total of 190 adults and pediatric patients with a variety of autoimmune rheumatologic diseases (systemic lupus erythematosus, rheumatoid arthritis, juvenile rheumatoid arthritis and spondyloarthrophathies were evaluated and tested for IgA and IgG antigliadin-antibodies and IgA antiendomysium antibodies. Patients with positive serum tests underwent endoscopic duodenal biopsies for pathology studies. RESULTS: There were four positive sera (2.1% for AGA IgA, all of which tested negative for AGA IgG and EmA. Three sera (1.6% tested positive for AGA IgG; all were negative for AGA IgA and EmA. The EmA test at a 1:2.5 serum dilution tested positive in 94 patients (49.5%; at a 1:5 serum dilution it was positive in 41 patients (21.6%. Eleven subjects tested positive for EmA at 1:40 dilution; and all of these tested negative for IgA tissue antitransglutaminase (tTG antibodies. Nine of the 11 EmA-positive patients and all 7 patients with positive antigliadin antibodies tests underwent duodenal endoscopic biopsies, and no significant changes were demonstrated in their duodenal mucosa. A positive EmA was associated with elevated optical density AGA IgA readings; however, there was no relationship between positive EmA and AGA IgG optical density readings. Prednisone and immunosuppressant use were unrelated to AGA IgA optical density readings or AGA IgG readings. These drugs were associated with fewer positive EmA tests. CONCLUSIONS: Positive AGAA, AGAG or EmA results are probably nonspecific for the presence of celiac disease among autoimmune rheumatologic disease patients. The intake of prednisone and immunosuprressant drugs seems to reduce the prevalence of IgA EmA, but it does not interfere with antigliadin antibodies tests.Further studies are required to estimate more accurately the prevalence of this disease in rheumatologic patients.CONTEXTO: Tanto os pacientes com doenças reumatológicas autoimunes quanto os com doença celíaca costumam apresentar vários tipos de autoanticorpos, muitos deles ainda sem papel definido na etiopatogênese dessas afecções. Apesar de tratar-se de assunto controverso, é bastante citada na literatura a maior prevalência da doença celíaca em diversos grupos de pacientes reumatológicos. OBJETIVO: Investigar a prevalência de marcadores sorológicos positivos para doença celíaca: anticorpos antigliadina (AGA classes IgA e IgG (AGAA e AGAG e anticorpos antiendomísio classe IgA (EmA, em pacientes com doenças reumatológicas autoimunes. Procurou-se também avaliar a correlação entre a positividade dos testes sorológicos com o uso de prednisona e de medicamentos imunossupressores. MÉTODOS: Foram avaliados 190 pacientes adultos e pediátricos com doenças reumatólogicas variadas (lúpus eritematoso sistêmico, artrite reumatóide, artrite reumatóide juvenil e espondiloartropatias. Em todos foram realizadas pesquisas de AGAA e AGAG e de EmA, encaminhando-se os casos positivos para biopsias endoscópica duodenal e estudos histológicos. RESULTADOS: Houve quatro soros positivos (2,1% para AGAA, todos com resultados negativos para AGAG e EmA. Três soros (1,6% tiveram resultados positivos para AGAG, todos com resultados negativos para AGAA e EmA. Na pesquisa de EmA, a diluição do soro em 1:2,5 mostrou resultados positivos em 94 pacientes (49,5% e na diluição de 1:5, em 41 (21,6%. Em 11 indivíduos obteve-se resultado positivo para EmA na diluição 1:40 e todos eles tiveram resultado negativo para a pesquisa de anticorpos antitransglutaminase tecidual IgA (tTg. Nove dos 11 pacientes positivos para EmA e todos os 7 pacientes com anticorpos antigliadina positivos foram submetidos a biopsia duodenal endoscópica, não se constatando alterações significativas da mucosa duodenal em nenhum deles. Todos os soros positivos para EmA apresentaram resultados negativos para a pesquisa de anticorpos antitransglutaminase tecidual classe IgA (tTG. A positividade para EmA associou-se a leituras de densidade óptica mais altas para AGAA. O mesmo não foi observado para AGAG. O uso de prednisona e de imunossupressores não se relacionou às leituras de densidade óptica dos AGAA, tampouco dos AGAG. O uso dessas medicações se relacionou, contudo, a menor positividade para EmA. CONCLUSÃO: Resultados positivos para AGAA, AGAG ou EmA demonstraram-se inespecíficos para a presença de doença celíaca em pacientes com doenças reumatológicas autoimune. O uso de prednisona e drogas imunossupressoras parece diminuir a prevalência de anticorpos antiendomísio IgA, mas não de anticorpos antigliadina. Mais estudos são necessários para se avaliar com maior precisão a prevalência da doença celíaca em pacientes reumatológicos.

    The Belo Monte hydropower plant's low generation cost is among the arguments used by Centrais Eletricas do Norte do Brazil (ELETRONORTE), a Brazilian state electric utility, to make possible its construction. This paper shows that the generation cost presented by ELETROBRAS is very low in relation to the world pattern of cost and probably unrealistic. It also shows that the generation cost cannot be used separately to determine the Belo Monte dam's economic feasibility. There is the need to include other costs, such as: socio environmental degradation and control, financial compensation for using the hydraulic resources, transmission and thermal backup stations, beyond, evidently, generation cost for assuring the credibility of the Belo Monte hydropower plant's economic analysis.

Methods: Cross-sectional study with stratified, random sample consisting of 539 students. The evaluation consisted of three protocols: orofacial motor skill protocol, adapted from the Myofunctional Evaluation Guidelines; the Child Language Test ABFW - Phonology; and a simplified auditory processing evaluation. Descriptive and associative statistical analyses were performed using Epi Info software, release 6.04. Chi-square test was applied to compare proportion of events and analysis of variance was used to compare mean values. Significance was set at p≤0.05. Results: Of the studied subjects, 50.1% had at least one of the assessed disorders; of those, 33.6% had oral language disorder, 17.1% had orofacial motor skill impairment, and 27.3% had auditory processing disorder. There were significant associations between auditory processing skills’ impairment, oral language impairment and age, suggesting a decrease in the number of disorders with increasing age. Similarly, the variable "one or more speech, language and hearing disorders" was also associated with age. Conclusions: The prevalence of speech, language and hearing disorders in children was high, indicating the need for research and public health efforts to cope with this problem.

    Full Text Available This study aims to determine spatial patterns of mortality and morbidity for five health problems in an urban environment: homicides, adolescent pregnancy, asthma hospitalization, and two vector-borne diseases, dengue and visceral leishmaniasis. All events were obtained through the city health database and geoprocessed using residential addresses and 80 planning units consisting of census tracts. We used thematic maps, proportionate mortality/morbidity ratios by planning unit, and the overlapped rank of the 20th worse planning unit rates for each event. A spatial pattern of high rates of homicides, proportion of young mothers, and hospitalization due to asthma overlapped in socially and economically disadvantaged areas. For the two vector-borne diseases, high rates with great dispersion were found in underprivileged areas, in contrast with very low rates among higher income areas. The results indicated the coexistence of heavier disease burden for residents of urban areas where poverty and lack of effective public health policies may be modulating social health problems. For the two vector-borne diseases, an environmental intervention in one mosquito-borne disease might be playing a role in the other's incidence.

    Fearnside, Phillip M

    2006-07-01

    Hydroelectric dams represent major investments and major sources of environmental and social impacts. Powerful forces surround the decision-making process on public investments in the various options for the generation and conservation of electricity. Brazil's proposed Belo Monte Dam (formerly Kararaô) and its upstream counterpart, the Altamira Dam (better known by its former name of Babaquara) are at the center of controversies on the decision-making process for major infrastructure projects in Amazonia. The Belo Monte Dam by itself would have a small reservoir area (440 km2) and large installed capacity (11, 181.3 MW), but the Altamira/Babaquara Dam that would regulate the flow of the Xingu River (thereby increasing power generation at Belo Monte) would flood a vast area (6140 km2). The great impact of dams provides a powerful reason for Brazil to reassess its current policies that allocate large amounts of energy in the country's national grid to subsidized aluminum smelting for export. The case of Belo Monte and the five additional dams planned upstream (including the Altamira/Babaquara Dam) indicate the need for Brazil to reform its environmental assessment and licensing system to include the impacts of multiple interdependent projects.

This law has caused a diversified situation by allowing flexibility and delegating autonomy to teaching institutions to decide on school time's organization. The data indicate that the public schools are moving more quickly towards an organization based on cycles, whereas the private ones are more inclined to keep grades. Recent statistic data, supplied by the National Institute of Pedagogical Studies and Research Anísio Teixeira - Inep -, prove it. The reasons why public teaching institutions adopt the learning cycle have been discussed in many publications. However, when the private schools are focused, it is not known what the reasons for non-adhesion to learning cycle are, as well as the motives that make them to maintain the graded system.

    Full Text Available Os projetos de conjuntos habitacionais têm sido elaborados por profissionais competentes, cujo propósito é o de assentar famílias de baixa renda, em condições adequadas, com o menor custo possível. Ao serem ocupadas por seus moradores, essas casas passam por transformações dos mais variados aspectos, que vão das interferências internas até ao comprometimento da paisagem de todo o assentamento. Projetos que aparentemente são pensados e concebidos para atender com qualidade a essa demanda não vêm sendo apropriados por seus moradores conforme o estabelecido. Os objetivos do presente trabalho são analisar quais fatores provocam tais transformações na paisagem local, além de verificar aqueles que podem contribuir para que esse atendimento às camadas menos favorecidas se torne mais eficaz.

    Full Text Available A major evolution in the behavior of consumption of energy sources (coal, firewood, electricity and fuel gas in Brazilian’s houses was observed in the twentieth century. These sources were generally used for lighting, heating water and the environment and food preparation. New developments are being observed today in the residential segment in the state of Minas Gerais due to insertion of natural gas in this sector. Searching for an understanding of consumer behavior across the acceptance of this new fuel, a qualitative exploratory research was conducted. As a starting point we adopted the technology acceptance model (TAM. Based on the interviews, it was possible to analyze the variables of acceptance of natural gas. It was found mainly the influence such as safety, cost reduction, reliability of supply, reduction of effort in cleaning the stove and cookware, convenience, past experiences and opinions of others. With this information it was possible to build a model for acceptance of natural gas for future research, in which are inserted the constructs: Perceived Usefulness, Perceived Ease, Perceived Cost and Past Experiences. O século XX representou uma grande evolução no comportamento de consumo de fontes de energia (carvão, lenha, energia elétrica e gases combustíveis nas residências brasileiras. Essas fontes eram geralmente utilizadas para iluminação, aquecimento de água e ambiente e preparo de alimentos. Nova evolução está sendo observada hoje no segmento residencial no estado de Minas Gerais em função da inserção do gás natural nesse setor. Com a intenção de entender o comportamento dos consumidores frente à aceitação desse novo combustível, foi realizada uma pesquisa exploratória qualitativa. Como ponto de partida adotou-se o modelo de aceitação da tecnologia (TAM. Foram entrevistados 11 consumidores de gás natural em uma capital brasileira. Baseado nas entrevistas realizadas, foi possível analisar as variáveis de aceitação do gás natural. Verificou-se, principalmente, a influência de variáveis tais como segurança, redução de custo, confiabilidade de fornecimento, redução de esforço na limpeza do fogão e panelas, comodidade, experiências passadas e opinião de terceiros. De posse dessas informações, foi possível elaborar um modelo de aceitação do gás natural para pesquisa futuras, no qual estão inseridos os constructos: Utilidade Percebida, Facilidade Percebida, Custo Percebido e Experiências Passadas.

    Full Text Available Se presenta el segundo reporte de los resultados de los antibiogramas obtenidos en la Red Cubana de Laboratorios con el Sistema DIRAMIC pertenecientes a la región oriental, el cual cubre un total de 2 516 ensayos. Los datos fueron analizados utilizando el sistema de programas "Mapas Microbianos", el cual permite confeccionar el esquema estadístico de circulación de los diferentesmicroorganismos y su resistencia y sensibilidad ante los antibióticos utilizados, así como determinar los patrones de susceptibilidad a los antibióticos. Se reporta además, la frecuencia global de aparición de los microorganismos aislados y la distribución de los aislamientos por tipos de muestras. Los microorganismos aislados con mayor frecuencia fueron: Escherichia coli, Proteus sp., Klebsiella sp., Shigella sp., Enterobacter sp., Staphylococcus coagulasa negativa, Staphylococcus aureus y Pseudomonas sp. Los tipos de muestras más analizados fueron: hemocultivo, urocultivo, exudado faríngeo, coprocultivo, exudado nasal y líquido céfalo raquídeo. Se comprobó que la utilidad de los antibióticos ensayados mantiene vigencia, aún para los más antiguos. En el caso del cloranfenicol, la amikacina, la gentamicina, la kanamicina y la ciprofloxazina se apreciaron bajos niveles de resistencia. Sin embargo, el grupo de antibióticos donde se encuentran penicilina, ampicilina, cefazolina, sulfametoxazol + trimetropim y ceftriaxona presentaron niveles de resistencia elevados, por encima del 50 %, por lo que deben ser vigilados a corto plazo. Este tipo de trabajo brinda una valiosa información para definir la política de uso de los antibióticos sobre la base del conocimiento de los niveles de su resistencia. Esto permite seleccionar el agente antimicrobiano a utilizar en terapias empíricas, así como recomendar que un determinado antibiótico sea sometido a períodos de reposocuando presenta bajos niveles de susceptibilidad.

    Full Text Available Among many issues related to solid waste, one stands out more and more, due to recent legislation linked to the area (National Policy on Solid Waste - Law 12.305/2010, which stresses the concept of reverse logistics, in which the producer is responsible for waste disposal related to the products manufactured by them. This study aims to perform an analysis of the disposal process of electronic waste from computers within the city limits of Contagem/ MG, in order to understand the reality of these wastes disposal, analyzing the population view, the management bodies and a recycling company, within the logic of reverse logistics. Data collection was the methodological procedure. The results showed that when it comes to recycling, there isn´t a chain that can incorporate these waste efficiently yet, showing the presence of only one company in the metropolitan region of Belo Horizonte, considering that the majority of screened waste is sent out of the State of Minas Gerais and abroad. In relation to the population, there is a repetition of the same mistakes from the past, with the overvaluation of economic growth at the expense of environmental issues. Finally, regarding the work, several limitations were found as lack of historical sales data, lack of data on the equipment life, the virtual absence of data from these items recycling.

    Full Text Available O artigo desenvolve a ideia de que a experiência do Belo inclui necessariamente a dimensão da dor, a partir das obras de Freud e de Nietzsche. No primeiro autor, investigam-se a dor da antecipação do luto em face da transitoriedade da beleza, a importância do conceito de sublimação e a análise sobre a experiência perturbadora de Freud diante da estátua de Moisés, de Michelangelo. No segundo, apresentam-se as principais ideias do livro O Nascimento da tragédia para demonstrar como a arte possui o poder de transformar o vazio em vitalidade, pois o sublime desloca a náusea e o horror da existência em representações com as quais é possível viver. Por isso, defende--se que o trágico supõe uma estética próxima do feio e do dissonante, fazendo do Belo uma experiência que inclui as dimensões da dor e do horror.

    The production of horizontally aligned carbon nanotubes offers a rapid means of realizing a myriad of self-assembled near-atom-scale technologies - from novel photonic crystals to nanoscale transistors. The ability to reproducibly align anisotropic nanostructures has huge technological value. Here we review the present state-of-the-art in horizontal carbon nanotube alignment. For both in and ex situ approaches, we quantitatively assess the reported linear packing densities alongside the degree of alignment possible for each of these core methodologies. PMID:27546174

    2006-01-01

    In this paper we give a geometric interpretation of the notion of the horizontal mean curvature which is introduced by Danielli-Garofalo-Nhieu and Pauls who recently introduced sub-Riemannian minimal surfaces in Carnot groups. This will be done by introducing a natural nonholonomic connection which is the restriction (projection) of the natural Riemannian connection on the horizontal bundle. For this nonholonomic connection and (intrinsic) regular hypersurfaces we introduce the notions of the horizontal second fundamental form and the horizontal shape operator. It turns out that the horizontal mean curvature is the trace of the horizontal shape operator.

Devido à escassez de trabalhos que tratam especificamente de óxidos de Mn em solos brasileiros e seu conteúdo muito elevado em alguns solos do Quadrilátero Ferrífero (MG, este estudo objetivou caracterizar a química e a mineralogia desses óxidos nos solos dessa região, estratificando-os conforme os materiais de origem e posições na paisagem. O trabalho foi desenvolvido em uma área representativa do Quadrilátero Ferrífero, referente à Área de Proteção Ambiental da Região Metropolitana de Belo Horizonte - APA Sul RMBH, com extensão de 1.625,32 km²; a amostragem foi direcionada para a caracterização de solos com elevado teor de Mn, relacionados a três materiais de origem distintos: itabiritos, dolomitos ferruginosos e serpentinitos, tendo sido incluídos ainda alguns solos provenientes de outros materiais de origem, dentro do Quadrilátero. Alguns solos do Quadrilátero Ferrífero possuem teores de Mn na fração terra fina extraordinariamente elevados, principalmente aqueles relacionados aos dolomitos ferruginosos da Formação Gandarela. Foram identificados diversos minerais de Mn na fração argila dos solos, sem quaisquer pré-tratamentos de concentração, representados por todoroquita, litioforita e, ainda, pirolusita. A influência do material de origem no contexto deste estudo foi superior àquela da posição na paisagem e grau de intemperismo de solos ricos em Mn.

    Solar energy is collected by using a vertical deflector assembly, a stationary reflector and a horizontally mounted solar collector. The deflector assembly contains a plurality of vanes which change the direction of the solar energy to the vertical, while constantly keeping the same side of the deflector facing the sun. The vertical rays are then reflected off the stationary reflector and are then absorbed by the collector.

    1997-04-01

    An update of horizontal well drilling in Manitoba was provided. Manitoba`s productive formations are: (1) the Bakken Formation, (2) the Lodgepole Formation, (3) the Mission Canyon Formation, (4) the Amaranth Formation, and (5) the Melita Formation. A total of 28 exploratory wells and 29 development wells, including 11 horizontal wells were drilled in 1996. The 11 horizontal wells accounted for 30 per cent of the drilling meterage. The leading drillers for horizontal wells in Manitoba are Tundra Oil and Gas, Chevron, Anderson and HCO. Production from horizontal wells in 1996 totaled 310 cubic meter per day. To date, no horizontal wells have been drilled in the Bakken Formation. The least successful horizontal well application has been in the Lodgepole Formation. A summary of horizontal well production was provided for each Formation. 4 tabs., 10 figs.

  3. Well Spacing for Horizontal Wells

    Full Text Available In the developing phase of a hydrocarbon reservoir and planning for drilling the production wells, it is necessary to drill the wells in an appropriate spacing to achieve maximum economic revenues during the reservoir life span. Well spacing which is the real location and interrelationship between producing oil or gas wells in an oil field is an important parameter. It is determined for the maximum ultimate production of a given reservoir and should be taken in consideration during well planning to avoid drilling of unnecessary wells. This study presents the concept of drainage area on horizontal well and horizontal productivity indices with different equations and their applications. A user friendly Excel Spreadsheet program was developed to calculate the productivity values of horizontal wells using three major available productivity equations. Also, the developed spreadsheet program was used to evaluate the effect of well spacing on the productivities of horizontal wells using productivity index approach and drainage area concept. It also helps to review the comparison between vertical and horizontal wells spacing based on drainage area concept. This program was validated, and then was used to study the effect of horizontal well length on the ratio of horizontal well productivity to vertical well productivity. The results show that higher ratio of horizontal well productivity to vertical well productivity values are obtained with increase length of the horizontal well. It is a very useful tool for making decision about the application of well spacing for horizontal wells.

  4. PRODUCTIVITY OF FRACTURED HORIZONTAL WELLS

    2009-12-01

    Full Text Available The interest and performance of horizontal drilling and completions has increased during the last two decades. Horizontal wells are advantageous compared to vertical wells in thin reservoirs, reservoirs with favorable vertical permeability and reservoirs with water and gas coning problems. In many reservoirs, the ratio of horizontal permeability to the vertical permeability is substantially larger than one and often is close to 10. Thus, these reservoirs are very good candidates for hydraulic fracturing. By hydraulic fracturing one or more fractures are created, which can be longitudinal or orthogonal. By that, flow is altered and it mostly conducts horizontally through reservoir toward horizontal wellbore. With this altered flow, fluid is produced faster, with less pressure loss by fluid unit of produced fluid. Some of the existing mathematical models to determine the productivity of multifractured horizontal wells are presented in this work (the paper is published in Croatian.

    International Nuclear Information System (INIS)

    Sorption of technetium, plutonium and curium by sterile and natural silts taken from the Beloe lake in Kosino, Moscow region, has been studied. It is shown that in 4.5 months technetium sorption by natural silts has reached 98%. The mechanism of technetium sorption involves sulfide formation, which transfers the original soluble pertechnetate-ion into insoluble technetium (7) and (4) sulfides. Sorption of the actinides by natural silts amounts to 98%, the one by sterile silts-46%. The solid/liquid phase ratio is 2.3·10-2 g/ml. 14 refs., 2 figs., 2 tabs

  6. Almost horizontal turbulence

    International Nuclear Information System (INIS)

    The paper is published without modifications. Kolmogorov's manuscript was apparently prepared during his participation in one of expeditions of the ship 'D. Mendeleev' to the Atlantic Ocean (1969) or in a circumnavigation of the world (1971) organized by the Institute for Oceanology led at the time by A.S. Monin. As Kolmogorov himself wrote, the choice of the topic was stimulated by observations concerning '...meanders with horizontal sizes of hundreds of kilometers on a flow involving a layer of hundreds of meters, with subsequent disintegration of these meanders into vortices gradually decreasing in size to several kilometers'. In modern terminology, the paper is devoted to the problem of intensive mixing in pycnoclines, that is, thin layers of stratified fluid, caused by internal waves whose frequencies are less than the Brent-Vaeisaelae frequency. Here I would like to note two circumstances. The first is the scientific insight characteristic for Kolmogorov; this very approach was later reflected in numerous publications (see, for instance, the monograph by V.S. Modevich, V.I. Nikulin, and A.G. Stetsenko 'Dynamics of internal mixing in a stratified medium', Institute for Hydromechanics, Academy of Sciences of Ukraine, Naukova Dumka, Kiev 1988). The second, the more significant in my opinion, is the genuine intellectual curiosity and breadth of thought of this great thinker, who studied not only the most abstract mathematical constructions but also got his head out of the clouds with great interest to solve concrete applied problems

    Full Text Available Em 1992, foi obsewada lesão cutânea por Leishmania em um cão do município de Sabará, Minas Gerais, onde já haviam sido registrados casos humanos de leishmaniose tegumentar. O parasita foi caracterizado como pertencente ao subgênero Viannia, ao qual pertence a Leishmania braziliensis, principal espécie encontrada tia região sudeste do Brasil. Com o objetivo de determinar o papel do cão no ciclo de transmissão da doença, foi realizado um inquérito canino na área. Foram examinados 631 cães, sendo a soroprevalência para leishmaniose igual a 3,2%. Foi observada a proximidade ou presença no mesmo domicílio de cães e pessoas doentes. Este aspecto fala a favor da transmissão domiciliar ou peridomiciliar, com o cão infectado podendo atuar como fator de risco nesta área periurbana. Entretanto, a baixa soroprevalência encontrada deve-se provavelmente ao pequeno papel deste animal na transmissão da doença neste foco recente da doença.In 1992, a dog naturally infected with Leishmania was found in a periurban area of Sabará, State of Minas Gerais, where human cutaneous leishmaniasis had been previously described. The parasite was classified as Leishmania, subgenus Viannia, which L. braziliensis, the main species of parasite present in the southeast Brazil, also belongs. In order to assess the importance of the dog in the transmission cycle of the disease, a canine survey was undertaken. Six hundred thirty-one dogs were examined and the prevalence of seropositive dogs for crude Leishmania amazonensis antigen was 3.2%. The presence of infected people and seropositive dogs either near or in the same house was observed. This fact suggests some transmission in the domiciliar environment, with the dogs being a risk factor for human infection in that periurban area. In the other hand, the low percentage of seropositive dogs points towards a secondary importance of these animals in the transmission of Leishmaniasis in that recentfocus of the disease.

    The concentration of radon in the soil gas is an important indicator to predict the radon geologic potential, usually indicated by Geological Radon Potential - GEORP, which is defined as the percent number of dwellings with indoor air radon concentration above the U.S.EPA action limit. The objective of this work was to investigate the distribution of radon concentration in soil gas and its relation with the pedologies and lithologies in the RMBH. The radon concentrations in soil gas were determined by using an AlphaGUARD monitor at 150 measurement points over the lithologies and pedologies of the area. The concentrations {sup 226}Ra were determined by gamma spectrometry (HPGe) and U and Th by ICP-MS. The permeabilities of the soil were determined by using the RADON-JOK permeameter. Regarding pedologies, the perferric Red Latosols had the highest concentrations, with arithmetic mean to 60.6 ± 8.7 kBq.m{sup -3}. Regarding lithologies, areas where the bedrocks are predominantly schists and metagraywackes showed the highest radon concentrations, with arithmetic mean to 46.5 ± 9.9 kBq.m{sup -3}. The areas of lithology or pedology, in which the average radon concentrations are the highest also exhibit higher GEORP, e.g. for the perferric Red Latosol pedology shows GEORP of 26,5%. In this pedology, over 50% of the measurement points shows radon concentrations above of 50.0 kBq.m{sup -3}, that, by the 'Swedish Criteria' classifies the area as high radon risk. The correlation with GEORP is even more significant when the radon concentration in soil gas is combined with soil permeability, through the Soil Radon Index indicator. (author)

    The Nuclear Technology Development Centre/Brazilian Commission for Nuclear Energy, CDTN/CNEN, is the only Brazilian Institution to apply the k0-standardisation method of instrumental neutron activation technique determining elements using its own nuclear reactor, TRIGA MARK I IPR-R1. After changes in the reactor core configuration, the reactor neutron flux distribution in typical irradiation channels had to be updated, as well as the parameters f and α, needed to apply the k0-method of neutron activation analysis. The neutron flux distribution in the rotary rack was evaluated through the specific count rate of 198Au and the parameters f and α, were determined in five selected channels applying the "Cd-ratio for multi-monitor" method, using a set of Al-(0.1%)Au and Zr (99.8%) monitors. Several reference materials were analysed, indicating the effectiveness of the improved method.

    Full Text Available The clinical and public health importance of indeterminate results in HIV-1/2 testing is still difficult to evaluate in volunteer blood donors. At Fundação Hemominas, HIV-1/2 ELISA is used as the screening test and, if reactive, is followed by Western blot (WB. We have evaluated 84 blood donors who had repeatedly reactive ELISA tests for HIV-1/2, but indeterminate WB results. Sixteen of the 84 donors (19.0% had history of sexually transmitted diseases; 18/84 (21.4% informed receiving or paying for sex; 3/84 (3.6% had homosexual contact; 2/26 women (7.6% had past history of multiple illegal abortions and 3/84 (3.6% had been previously transfused. Four out of 62 donors (6.5% had positive anti-nuclear factor (Hep2, with titles up to 1:640. Parasitological examination of the stool revealed eggs of S. mansoni in 4/62 (6.4% donors and other parasites in 8/62 (12.9%. Five (5.9% of the subjects presented overt seroconversion for HIV-1/2, 43/84 (51.2% had negative results on the last visit, while 36/84 (42.9% remained WB indeterminate. Although some conditions could be found associated with the HIV-1/2 indeterminate WB results and many donors had past of risky behavior, the significance of the majority of the results remains to be determined.

Apesar de ser uma doença evitável, continuam ocorrendo epidemias localizadas. Objetivo: Descrever o perfil dos trabalhadores atendidos no Ambulatório de Doenças Profissionais do Hospital das Clínicas da Universidade Federal de Minas Gerais. Material e métodos: Foram estudados 300 prontuários de trabalhadores expostos à sílica em diversas atividades profissionais, atendidos no período de 1989 a 2000, sendo analisados dados clínico-ocupacionais, espirométricos e radiológicos. Realizaram-se análises univariadas, utilizando o teste do qui-quadrado e teste t. Resultados e conclusão: A média de idade dos pacientes expostos foi de 51 anos, com tempo médio de exposição de 15,6 anos. Diagnosticaram-se radiologicamente 126 (42% casos de silicose, constatando-se que, quanto mais avançada a categoria radiológica da doença, piores foram os resultados à espirometria e mais freqüentes as associações com tuberculose e com limitação crônica ao fluxo aéreo. O mercado de trabalho formal representou o principal vínculo empregatício, sendo a mineração a principal atividade exercida, responsável pela exposição de 197 indivíduos (66%. Os trabalhadores do mercado informal foram aqueles que apresentaram achados radiológicos indicativos de formas mais avançadas da doença, sugerindo piores condições de exposição à sílica, neste grupo de trabalhadores.Introduction: Silicosis is the most prevalent pneumoconiosis in Brazil, with most of the registered cases occurring in the State of Minas Gerais. Although it is a preventable disease, silicosis is still epidemic in some areas. Objective: To describe the profile of workers seen at the Clinics Hospital of the Federal University of Minas Gerais. Patients and methods: 300 medical records of silica-exposed workers in different occupations, seen between 1989-2000, were reviewed. Clinical and occupational information, radiographic and spirometric data were analyzed. Statistical methods included univariate analyses with chi-square and t tests. Results and conclusion: The mean age of the exposed patients was 51 years, with mean exposure duration of 15.6 years. 126/300 (42% were radiologically classified as cases of silicosis. Increasing grades of profusion were associated with lower spirometric indices and more frequent associations with tuberculosis and chronic airflow limitation. Most of the workers were regularly registered employees and the main occupational activity was mining, accounting for the exposure of 197 (66% workers. Non-registered workers presented more severe radiological grades of silicosis, suggesting, possibly, worse conditions of silica exposure in this group of workers.

    We investigate the properties of orphan penumbrae, which are photospheric filamentary structures observed in active regions near polarity inversion lines that resemble the penumbra of regular sunspots but are not connected to any umbra. We use Hinode data from the Solar Optical Telescope to determine the properties of orphan penumbrae. Spectropolarimetric data are employed to obtain the vector magnetic field and line-of-sight velocities in the photosphere. Magnetograms are used to study the overall evolution of these structures, and G-band and Ca II H filtergrams are to investigate their brightness and apparent horizontal motions. Orphan penumbrae form between regions of opposite polarity in places with horizontal magnetic fields. Their magnetic configuration is that of $\\Omega$-shaped flux ropes. In the two cases studied here, the opposite-polarity regions approach each other with time and the whole structure submerges as the penumbral filaments disappear. Orphan penumbrae are very similar to regular penumbr...

    Using a spatial competition framework with three ex ante identical firms, we study the effects of a horizontal merger on quality, price and welfare. The merging firms always reduce quality. They also increase prices if demand responsiveness to quality is sufficiently low. The non-merging firm, on the other hand, always responds by increasing both quality and prices. Overall, a merger leads to higher average prices and quality in the market. The welfare implications of a merger are not clea...

  7. Horizontally oriented plates in clouds

    Bréon, François-Marie

    2011-01-01

    Horizontally oriented plates in clouds generate a sharp specular reflectance signal in the glint direction, often referred to as "subsun". This signal (amplitude and width) may be used to analyze the relative area fraction of oriented plates in the cloud top layer and their characteristic tilt angle to the horizontal. We make use of spaceborne measurements from the POLDER instrument to provide a statistical analysis of these parameters. More than half of the clouds show a detectable maximum reflectance in the glint direction, although this maximum may be rather faint. The typical effective fraction (area weighted) of oriented plates in clouds lies between 10-3 and 10-2. For those oriented plates, the characteristic tilt angle is less than 1 degree in most cases. These low fractions imply that the impact of oriented plates on the cloud albedo is insignificant. The largest proportion of clouds with horizontally oriented plates is found in the range 500-700 hPa, in agreement with typical in situ observation of p...

  9. Bubble shape in horizontal and near horizontal intermittent flow

    International Nuclear Information System (INIS)

    Highlights: • The bubble shapes in intermittent flows are presented experimentally. • The nose-tail inversion phenomenon appears at a low Froude number in downward pipe. • Transition from plug to slug flow occurs when the bubble tail changes from staircase pattern to hydraulic jump. - Abstract: This paper presents an experimental study of the shape of isolated bubbles in horizontal and near horizontal intermittent flows. It is found that the shapes of the nose and body of bubble depend on the Froude number defined by gas/liquid mixture velocity in a pipe, whereas the shape of the back of bubble region depends on both the Froude number and bubble length. The photographic studies show that the transition from plug to slug flow occurs when the back of the bubble changes from staircase pattern to hydraulic jump with the increase of the Froude number and bubble length. The effect of pipe inclination on characteristics of bubble is significant: The bubble is inversely located in a downwardly inclined pipe when the Froude number is low, and the transition from plug flow to slug flow in an upward inclined pipe is more ready to occur compared with that in a downwardly inclined pipe

    2009-08-01

    Evidence that extremophiles are hardy and ubiquitous is helping to make panspermia a respectable theory. But even if life on Earth originally came from space, biologists assume that the subsequent evolution of life is still governed by the darwinian paradigm. In this review we show how panspermia could amend darwinism and point to a cosmic source for, not only extremophiles but, all of life. This version of panspermia can be called "strong panspermia." To support this theory we will discuss recent evidence pertaining to horizontal gene transfer, viruses, genes apparently older than the Earthly evolution of the features they encode, and primate-specific genes without identifiable precursors.

  12. Horizontal versus vertical plate motions

    Directory of Open Access Journals (Sweden)

    M. Cuffaro

    2006-07-01

    Full Text Available We review both present and past motions at major plate boundaries, which have the horizontal component in average 10 to 100 times faster (10–100 mm/yr than the vertical component (0.01–1 mm/yr in all geodynamic settings. The steady faster horizontal velocity of the lithosphere with respect to the upward or downward velocities at plate boundaries supports dominating tangential forces acting on plates. This suggests a passive role of plate boundaries with respect to far field forces determining the velocity of plates. The forces acting on the lithosphere can be subdivided in coupled and uncoupled, as a function of the shear at the lithosphere base. Higher the asthenosphere viscosity, more significant should be the coupled forces, i.e., the mantle drag and the trench suction. Lower the asthenosphere viscosity, more the effects of uncoupled forces might result determinant, i.e., the ridge push, the slab pull and the tidal drag. Although a combination of all forces acting on the lithosphere is likely, the decoupling between lithosphere and mantle suggests that a torque acts on the lithosphere independently of the mantle drag. Slab pull and ridge push are candidates for generating this torque, but, unlike these boundary forces, the advantage of the tidal drag is to be a volume force, acting simultaneously on the whole plates, and being the decoupling at the lithosphere base controlled by lateral variations in viscosity of the low-velocity layer.

    2007-09-01

    Full Text Available Abstract Background Horizontal gene transfer (HGT, the non-genealogical transfer of genetic material between different organisms, is considered a potentially important mechanism of genome evolution in eukaryotes. Using phylogenomic analyses of expressed sequence tag (EST data generated from a clonal cell line of a free living dinoflagellate alga Karenia brevis, we investigated the impact of HGT on genome evolution in unicellular chromalveolate protists. Results We identified 16 proteins that have originated in chromalveolates through ancient HGTs before the divergence of the genera Karenia and Karlodinium and one protein that was derived through a more recent HGT. Detailed analysis of the phylogeny and distribution of identified proteins demonstrates that eight have resulted from independent HGTs in several eukaryotic lineages. Conclusion Recurring intra- and interdomain gene exchange provides an important source of genetic novelty not only in parasitic taxa as previously demonstrated but as we show here, also in free-living protists. Investigating the tempo and mode of evolution of horizontally transferred genes in protists will therefore advance our understanding of mechanisms of adaptation in eukaryotes.

In the two cases studied here, the opposite-polarity regions approach each other with time and the whole structure submerges as the penumbral filaments disappear. Orphan penumbrae are very similar to regular penumbrae, including the existence of strong gas flows. Therefore, they could have a similar origin. The main difference between them is the absence of a "background" magnetic field in orphan penumbrae. This could explain most of the observed differences. Conclusions: The fast flows we detect in orphan penumbrae may be caused by the siphon flow mechanism. Based on the similarities between orphan and regular penumbrae, we propose that the Evershed flow is also a manifestation of siphon flows.

    The descent image motion estimation system (DIMES) is a system of hardware and software, designed for original use in estimating the horizontal velocity of a spacecraft descending toward a landing on Mars. The estimated horizontal velocity is used in generating rocket-firing commands to reduce the horizontal velocity as part of an overall control scheme to minimize the landing impact. DIMES can also be used for estimating the horizontal velocity of a remotely controlled or autonomous aircraft for purposes of navigation and control.

    In higher organisms such as vertebrates, it is generally believed that lateral transfer of genetic information does not readily occur, with the exception of retroviral infection. However, horizontal transfer (HT) of protein coding repetitive elements is the simplest way to explain the patchy distribution of BovB, a long interspersed element (LINE) about 3.2 kb long, that has been found in ruminants, marsupials, squamates, monotremes, and African mammals. BovB sequences are a major component of some of these genomes. Here we show that HT of BovB is significantly more widespread than believed, and we demonstrate the existence of two plausible arthropod vectors, specifically reptile ticks. A phylogenetic tree built from BovB sequences from species in all of these groups does not conform to expected evolutionary relationships of the species, and our analysis indicates that at least nine HT events are required to explain the observed topology. Our results provide compelling evidence for HT of genetic material that has transformed vertebrate genomes.

    Knowledge transfer is widely emphasized as a strategic issue for firm competition. A model for intra-firm horizontal knowledge transfer is proposed to model horizontal knowledge transfer to solve some demerits in current knowledge transfer researches. The concept model of intra-firm horizontal knowledge transfer was described and a framework was provided to define the main components of thetransfer process. Horizontal knowledge transfer is that knowledge is transferred from the source to the same hierarchical level recipients as the target. Horizontal knowledge transfer constitutes a strategic area of knowledge management research. However, little is known about the circumstances under which one particular mechanism is the most appropriate. To address these issues, some significant conclusions are drawn concerning knowledge transfer mechanisms in a real-world setting.

  20. Horizontal Canal Benign Positional Vertigo

    1998-03-01

    Full Text Available Benign paroxysmal positional vertigo (BPPV is a syndrome characterized by transient episodes of vertigo in association with rapid changes in head position in Dix-Halpike Maneuver. This kind of vertigo is thought to be caused by migration of otoconial debris into canals other than the posterior canal, such as the anterior or lateral canals. It is also theoretically possible for many aberrant patterns of BPPV to occur from an interaction of debris in several canals, location of debris within the canal, and central adaptation patterns to lesions. The symptoms of BPPV are much more consistent with free-moving densities (canaliths in the posterior SCC rather than fixed densities attached to the cupula. While the head is upright, the particles sit in the PSC at the most gravity-dependent position. The best method to induce and see vertigo and nystagmus in BPPV of the lateral semicircular canal is to rotate head 90°while patient is in the supine position, nystagmus would appear in the unaffected side weaker but longer than the affected side. canal paresis has been described in one third of the patients with BPPV. Adaptation which is one of the remarkable features of BPPV in PSC is rarely seen in LSC. Rotations of 270° or 360° around the yaw axis (the so-called barbecue maneuver toward the unaffected ear are popular methods for the treatment of geotropic HC-BPPV. These maneuvers consist of sequential head turning of 90° toward the healthy side while supine. With these maneuvers, the free-floating otoconial debris migrates in the ampullofugal direction, finally entering the utricle through the nonampullated end of the horizontal canal. This kind of vertigo recovers spontaneously more rapidly and suddenly.

    2002-02-01

    Bacterial genomes are extremely dynamic and mosaic in nature. A substantial amount of genetic information is inserted into or deleted from such genomes through the process of horizontal transfer. Through the introduction of novel physiological traits from distantly related organisms, horizontal gene transfer often causes drastic changes in the ecological and pathogenic character of bacterial species and thereby promotes microbial diversification and speciation. This review discusses how the recent influx of complete chromosomal sequences of various microorganisms has allowed for a quantitative assessment of the scope, rate and impact of horizontally transmitted information on microbial evolution.

  3. Productivity and injectivity of horizontal wells

    One of the key issues addressed was pressure drop in long horizontal wells and its influence on well performance. Very little information is available in the literature on flow in pipes with influx through pipe walls. Virtually all of this work has been in small diameter pipes and with single-phase flow. In order to address this problem new experimental data on flow in horizontal and near horizontal wells have been obtained. Experiments were conducted at an industrial facility on typical 6 1/8 ID, 100 feet long horizontal well model. The new data along with available information in the literature have been used to develop new correlations and mechanistic models. Thus it is now possible to predict, within reasonable accuracy, the effect of influx through the well on pressure drop in the well.

    Slow rotating waterwheels have been recently proposed as affordable sources of renewable energy in rural areas. In terms of hydraulic efficiency, classical horizontal waterwheels reach values on the order of 50%, being well below those obtained from overshot (71%), waterfall (66%) and, even, undershot (65%) vertical ones. Based on the study of an horizontal waterwheel built prior to 1940s that includes features from both elementary turbines and antique waterwheels, we conclude that horizontal waterwheels may actually reach hydraulic efficiencies as high as 81%. These quantitative results are obtained by analytical approximations and, more important, by numerical integrations through accurate computational fluid dynamics (CFD) simulations. In addition, we show that such a high hydraulic efficiency does not substantially vary when changing the net available head. We suggest that this relevant progress made on improving the efficiency of classical horizontal waterwheels may have implications in future designs of nano/micro hydropower devices. (author)

  5. Microstructure and fatigue properties of Mg-to-steel dissimilar resistance spot welds

    International Nuclear Information System (INIS)

    Highlights: ► Mg/steel dissimilar spot weld had the same fatigue strength as Mg/Mg similar weld. ► Crack propagation path of Mg/Mg and Mg/steel welds was the same. ► Penetration of Zn into the Mg base metal led to crack initiation of Mg/steel weld. ► HAZ weakening and stress concentration led to crack initiation of Mg/Mg weld. -- Abstract: The structural application of lightweight magnesium alloys in the automotive industry inevitably involves dissimilar welding with steels and the related durability issues. This study was aimed at evaluating the microstructural change and fatigue resistance of Mg/steel resistance spot welds, in comparison with Mg/Mg welds. The microstructure of Mg/Mg spot welds can be divided into: base metal, heat affected zone and fusion zone (nugget). However, the microstructure of Mg/steel dissimilar spot welds had three different regions along the joined interface: weld brazing, solid-state joining and soldering. The horizontal and vertical Mg hardness profiles of Mg/steel and Mg/Mg welds were similar. Both Mg/steel and Mg/Mg welds were observed to have an equivalent fatigue resistance due to similar crack propagation characteristics and failure mode. Both Mg/steel and Mg/Mg welds failed through thickness in the magnesium sheet under stress-controlled cyclic loading, but fatigue crack initiation of the two types of welds was different. The crack initiation of Mg/Mg welds was occurred due to a combined effect of stress concentration, grain growth in the heat affected zone (HAZ), and the presence of Al-rich phases at HAZ grain boundaries, while the penetration of small amounts of Zn coating into the Mg base metal stemming from the liquid metal induced embrittlement led to crack initiation in the Mg/steel welds.

    For the backfill hydraulic support as the key equipment for achieving integration of backfilling and coal mining simultaneously in the practical process, its characteristics will directly influence the backfill body’s compression ratio. Horizontal roof gap, as a key parameter of backfilling characteristics, may impact the backfilling effect from the aspects of control of roof subsidence in advance, support stress, backfilling process and the support design. Firstly, the reason why horizontal roof gap exists was analyzed and its definition, causes and connotation were introduced, then adopting the Pro/E 3D simulation software, three typical 3D entity models of backfill hydraulic supports were built, based on the influence of horizontal roof gap on backfilling effect, and influence rules of four factors, i.e. support height, suspension height, suspension angle and tamping angle, were emphatically analyzed on horizontal roof gap. The results indicate that, the four factors all have significant impacts on horizontal roof gap, but show differences in influence trend and degree, showing negative linear correlation, positive linear correlation, positive semi-parabolic correlation and negative semi-parabolic correlation, respectively. Four legs type is the most adaptive to the four factors, while six legs (II) type has the poorest adaptability, and the horizontal roof gap is small under large support height, small suspension height, small suspension angle and large tamping angle situation. By means of optimizing structure components and their positional relation and suspension height of backfill scrape conveyor in the process of support design and through controlling working face deployment, roof subsidence in advance, mining height and backfilling during engineering application, the horizontal roof gap is optimized. The research results can be served as theoretical basis for support design and guidance for backfill support to have better performance in backfilling.

    2010-01-01

    Full Text Available Background: Attempts to successfully regenerate lost alveolar bone have always been a clinician′s dream. Angular defects, at least, have a fairer chance, but the same cannot be said about horizontal bone loss. The purpose of the present study was to evaluate the prevalence of horizontal alveolar bone loss and vertical bone defects in periodontal patients; and later, to correlate it with the treatment modalities available in the literature for horizontal and vertical bone defects. Materials and Methods: The study was conducted in two parts. Part I was the radiographic evaluation of 150 orthopantomographs (OPGs (of patients diagnosed with chronic periodontitis and seeking periodontal care, which were digitized and read using the AutoCAD 2006 software. All the periodontitis-affected teeth were categorized as teeth with vertical defects (if the defect angle was ≤45° and defect depth was ≥3 mm or as having horizontal bone loss. Part II of the study comprised search of the literature on treatment modalities for horizontal and vertical bone loss in four selected periodontal journals. Results: Out of the 150 OPGs studied, 54 (36% OPGs showed one or more vertical defects. Totally, 3,371 teeth were studied, out of which horizontal bone loss was found in 3,107 (92.2% teeth, and vertical defects were found only in 264 (7.8% of the teeth, which was statistically significant (P<.001. Search of the selected journals revealed 477 papers have addressed the treatment modalities for vertical and horizontal types of bone loss specifically. Out of the 477 papers, 461 (96.3% have addressed vertical bone loss, and 18 (3.7% have addressed treatment options for horizontal bone loss. Two papers have addressed both types of bone loss and are included in both categories. Conclusion: Horizontal bone loss is more prevalent than vertical bone loss but has been sidelined by researchers as very few papers have been published on the subject of regenerative treatment

    Directory of Open Access Journals (Sweden)

    Nediljka Gaurina-Međimurec

    1998-12-01

    Full Text Available Main objective of horizontal driling is to place a drain-hole for a long distance within the pay zone to enhance productivity or injectivity. In drilling horizontal wells, more serious problems appear than in drilling vertical wells. These problems are: poor hole cleaning, excessive torque and drag, hole filling, pipe stucking, wellbore instability, loss of circulation, formation damage, poor cement job, and difficulties at logging jobs. From that reason, successful drilling and production of horizontal well depends largely on the fluid used during drilling and completion phases. Several new fluids, that fulfill some or all of required properties (hole cleaning, cutting suspension, good lubrication, and relative low formation damage, are presented in this paper.

    2011-01-01

    Horizontal mixing and the distribution of coherent structures in the global ocean are analyzed using Finite-Size Lyapunov Exponents (FSLE), computed for the surface velocity field derived from the Ocean general circulation model For the Earth Simulator (OFES). FSLEs measure horizontal stirring and dispersion; additionally, the transport barriers which organize the oceanic flow can roughly be identified with the ridges of the FSLE field. We have performed a detailed statistical study, particularizing for the behaviour of the two hemispheres and different ocean basins. The computed Probability Distributions Functions (PDFs) of FSLE are broad and asymmetric. Horizontal mixing is generally more active in the northern hemisphere than in the southern one. Nevertheless the Southern Ocean is the most active ocean, and the Pacific the less active one. A striking result is that the main currents can be classified in two 'activity classes': Western Boundary Currents, which have broad PDFs with large FSLE values, and Eas...

    Full Text Available Aims: This study evaluated the horizontal magnification of images taken from adults and pediatrics with PM 2002 CC Planmeca analogue machine. Materials and Methods: A series of 120 panoramic radiographs were obtained of 60 adults and 60 pediatrics. For all patients, negative impressions were used to make positive casts of the teeth. A caliper was used to measure the maximum mesiodistal length of the buccal surface of all teeth except canines on both casts and radiographs. The horizontal magnification factor was calculated for incisor, premolar, and molar regions by dividing the values obtained from the casts by the values obtained from the radiographs. Statistical Analysis: Independent t-test and one-way analysis of variance (ANOVA were used. Results: The results indicated that with regard to adults, maxillary and mandibular incisor regions, unlike the other two sessions, didn′t show significant difference of the mean magnification of horizontal dimension (P = 0.5. In pediatrics, the comparison between mean magnification factors of all subgroups showed significant difference (P < 0.0001. Despite the adults′ radiographs, the results of pediatrics′ radiographs showed significantly higher magnification than the index listed by the manufacturer of the radiographic machine used. Conclusion: The present study results point to the fact that PM 2002 CC Proline panoramic machine makes possible precise measurements on radiographs of adults′ jaws in the horizontal dimension.

    2005-01-01

    A versatile mechanical device provides support for a user engaged in any of a variety of resistive exercises in a substantially horizontal orientation. The unique features and versatility of the device promise to be useful in bedrest studies, rehabilitation, and specialized strength training. The device affords a capability for selectively loading and unloading of portions of the user s body through its support mechanisms, so that specific parts of the body can be trained with little or no effect on other parts that may be disabled or in the process of recovery from injury. Thus, the device is ideal for rehabilitation exercise programs prescribed by physicians and physical therapists. The capability for selective loading and support also offers potential benefits to strength and conditioning trainers and athletes who wish to selectively strengthen selected parts. The principal innovative aspect of the device is that it supports the subject s weight while enabling the subject, lying substantially horizontally, to perform an exercise that closely approximates a full standing squat. The device includes mechanisms that support the subject in such a way that the hips are free to translate both horizontally and vertically and are free to rotate about the line connecting the hips. At the same time, the shoulders are free to translate horizontally while the upper back is free to rotate about the line connecting the shoulders. Among the mechanisms for hip motion and support is a counterbalance that offsets the weight of the subject as the subject s pelvis translates horizontally and vertically and rotates the pelvis about the line connecting the hips. The counterbalance is connected to a pelvic support system that allows these pelvic movements. The subject is also supported at the shoulder by a mechanism that can tilt to provide continuous support of the upper back while allowing the rotation required for arching the back as the pelvis is displaced. The shoulder support

    Full Text Available Artificial bilayer containing reconstituted ion channels, transporters and pumps serve as a well-defined model system for electrophysiological investigations of membrane protein structure–function relationship. Appropriately constructed microchips containing horizontally oriented bilayers with easy solution access to both sides provide, in addition, the possibility to investigate these model bilayer membranes and the membrane proteins therein with high resolution fluorescence techniques up to the single-molecule level. Here, we describe a bilayer microchip system in which long-term stable horizontal free-standing and hydrogel-supported bilayers can be formed and demonstrate its prospects particularly for single-molecule fluorescence spectroscopy and high resolution fluorescence microscopy in probing the physicochemical properties like phase behavior of the bilayer-forming lipids, as well as in functional studies of membrane proteins.

  15. Detecting series periodicity with horizontal visibility graphs

    CERN Document Server

    Núñez, Angel M; Valero, Eusebio; Gómez, Jose Patricio; Luque, Bartolo

    2011-01-01

    The horizontal visibility algorithm has been recently introduced as a mapping between time series and networks. The challenge lies in characterizing the structure of time series (and the processes that generated those series) using the powerful tools of graph theory. Recent works have shown that the visibility graphs inherit several degrees of correlations from their associated series, and therefore such graph theoretical characterization is in principle possible. However, both the mathematical grounding of this promising theory and its applications are on its infancy. Following this line, here we address the question of detecting hidden periodicity in series polluted with a certain amount of noise. We first put forward some generic properties of horizontal visibility graphs which allow us to define a (graph theoretical) noise reduction filter. Accordingly, we evaluate its performance for the task of calculating the period of noisy periodic signals, and compare our results with standard time domain (autocorre...

  16. Assessment of the discharge regime and water budget of Belo Vrelo (source of the Tolišnica River, central Serbia

    Directory of Open Access Journals (Sweden)

    Čokorilo-Ilić Marina

    2014-01-01

    Full Text Available A sufficiently long spring discharge regime monitoring data set allows for a large number of analyses, to better understand the process of transformation of precipitation into a discharge hydrograph. It is also possible to determine dynamic groundwater volumes in a karst spring catchment area, the water budget equation parameters and the like. It should be noted that a sufficiently long data set is deemed to be a continuous spring discharge time series of more than 30 years. Such time series are rare in Serbia. They are generally much shorter (less than 15 years, and the respective catchment areas therefore fall into the “ungauged” category. In order to extend existing karst spring discharge time series, we developed a model whose outputs, apart from mean monthly spring discharges, include daily real evapotranspiration rates, catchment size and dynamic volume variation during the analytical period. So far the model has solely been used to assess the discharge regime and water budget of karst springs. The present paper aims to demonstrate that the model also yields good results in the case of springs that drain aquifers developed in marbles. Belo Vrelo (“White Spring”, source of the Tolišnica River, which drains marbles and marbleized limestones and dolomites of Čemerno Mountain, was selected for the present case study. [OI-176022

    This paper addresses the effect of horizontal mergers on prices. It is shown that if firms compete in quantities and marginal costs are nondecreasing, any profitable merger failing to generate technological synergies must harm consumers through higher prices, irrespective of entry conditions in the industry. However this result does not hold if products are differentiated and firms compete in prices. The implications for merger policy are discussed.

Based on drilling operation parameters, well structure and monitored parameters, the wellbore pressure and the gas reservoir permeability could be predicted theoretically for underbalanced horizontal drilling. Based on the monitored gas production along the well depth, the gas reservoir type could be identified.

    We investigate two-dimensional liquid bridges trapped between pairs of identical horizontal cylinders. The cylinders support forces due to surface tension and hydrostatic pressure which balance the weight of the liquid. The shape of the liquid bridge is determined by analytically solving the nonlinear Laplace-Young equation. Parameters that maximize the trapping capacity (defined as the cross-sectional area of the liquid bridge) are then determined. The results show that these parameters can ...

  2. Neutrino masses, magnetic moments, and horizontal symmetries

    International Nuclear Information System (INIS)

    We investigate the general structure of the neutrino mass and magnetic matrices in the presence of an unbroken horizontal symmetry. In particular, we study the compatibility of masslessness induced by such a symmetry and a non-zero magnetic moment. We show that in this case at least two of the charged leptons must have equal masses. Furthermore, we give a general definition of Dirac neutrinos and demonstrate that they are not necessarily associated with a lepton number. (Author) 15 refs

    Full Text Available Methyl mercury (MeHg is highly neurotoxic, affecting visual function in addition to other central nervous system functions. The effect of mercury intoxication on the amplitude of horizontal cell responses to light was studied in the retina of the fish Hoplias malabaricus. Intracellular responses were recorded from horizontal cells of fish previously intoxicated with MeHg by intraperitoneal injection (IP group or by trophic exposure (T group. Only one retina per fish was used. The doses of MeHg chloride administered to the IP group were 0.01, 0.05, 0.1, 1.0, 2.0, and 6.0 mg/kg. The amplitudes of the horizontal cell responses were lower than control in individuals exposed to 0.01 (N = 4 retinas, 0.05 (N = 2 retinas and 0.1 mg/kg (N = 1 retina, whereas no responses were recorded in the 1.0, 2.0, and 6.0 mg/kg groups. T group individuals were fed young specimens of Astyanax sp previously injected with MeHg corresponding to 0.75 (N = 1 retina, 0.075 (N = 8 retinas or 0.0075 (N = 4 retinas mg/kg fish body weight. After 14 doses, one every 5 days, the amplitude of the horizontal cell response was higher than control in individuals exposed to 0.075 and 0.0075 mg/kg, and lower in individuals exposed to 0.75 mg/kg. We conclude that intoxication with MeHg affects the electrophysiological response of the horizontal cells in the retina, either reducing or increasing its amplitude compared to control, and that these effects are related to the dose and/or to the mode of administration.

This study aimed at investigating risk factors associated with incident HIV infection in a MSM cohort-Project Horizonte, Belo Horizonte, Minas Gerais, Brazil.This is a nested case-control study in an ongoing open cohort of homosexual and bisexual men, carried out in 1994-2010, during which 1,085 volunteers were enrolled. Each HIV seroconverted volunteer (case was compared with three randomly selected HIV negative controls, matched by admission date and age (±3 years. During follow-up, 93 volunteers seroconverted and were compared with 279 controls.The risk factors associated with HIV seroconversion were: contact with partner's blood during sexual relations (OR 3.7; 95% CI 1.2-11.6, attendance at gay saunas in search for sexual partners (OR 2.6; 95% CI 1.3-5.4, occasional intake of alcohol when flirting and engaging in sexual activity (OR 2.5; 95% CI 1.3-5.1, inconsistent use of condoms in receptive anal sex (OR 2.4; 95% CI 1.1-5.4, little interest to look up information about AIDS (OR 2.6; 95% CI 1.0-6.7 particularly in newspapers (OR 3.4; 95% CI 1.4-8.1.This study shows that MSM are still engaging in risk behavior, such as unprotected anal intercourse, despite taking part in a cohort study on various preventive measures. New preventive strategies in touch with the epidemic's development and the specificities of this particular population are needed.

    Greenhill, Simon J; Currie, Thomas E; Gray, Russell D

    2009-06-22

    Phylogenetic methods have recently been applied to studies of cultural evolution. However, it has been claimed that the large amount of horizontal transmission that sometimes occurs between cultural groups invalidates the use of these methods. Here, we use a natural model of linguistic evolution to simulate borrowing between languages. The results show that tree topologies constructed with Bayesian phylogenetic methods are robust to realistic levels of borrowing. Inferences about divergence dates are slightly less robust and show a tendency to underestimate dates. Our results demonstrate that realistic levels of reticulation between cultures do not invalidate a phylogenetic approach to cultural and linguistic evolution.

    Full Text Available The granular medium is known as a protecting material for shock mitigation. We study the impulse absorption of an alignment of magnetic spheres placed horizontally under a non-uniform magnetic field. The phenomenon of the wave dispersion is presented. This system can absorb 85% ∼ 95% (88% ∼ 98% of the incident peak force (energy under the applied magnetic field strength in 0.1 T ∼ 1.0 T. The shock attenuation capacities are enhanced by the increment of field strength. With an intelligent control system, it is conceivable that the magnetic granular chain may offer possibilities in developing adaptive shock protectors.

    Michaelis, Max M.

    2014-01-01

    After a brief history of the Levitron, the first horizontal axis Levitron is reported. Because it is easy to operate, it lends itself to educational physics experiments and analogies. Precession and nutation are visualized by reflecting the beam from a laser pointer off the ‘spignet’. Precession is fundamental to nuclear magnetic resonance, magnetic resonance imaging, particle traps and the movement of bodies in space. Longitudinal and lateral bounce behaviour is explained via ‘the principle of gentle superposition’ of two traps: the micro-precessional and the macro-trap. Theory is initiated. Scaling experiments are mentioned. Industrial applications might follow. Patent pending.

    1992-10-01

    Sandstone reservoirs in the Gulf of Mexico typically do not form horizontal planes, and a predetermined course for a horizontal well cannot ensure that the well path will remain within the producing interval throughout the horizontal section. Detecting approaching bed boundaries and fluid contacts early enough to make the changes necessary to keep the well path in the producing interval is an important technical issue during the planning and drilling of horizontal wells. This paper reports that the first two horizontal wells drilled in the Gulf of Mexico achieved this objective with measurement-while-drilling (MWD) resistivity measurements and with supporting computer modeling for bed boundary detection.

  13. In-situ bioremediation via horizontal wells

    International Nuclear Information System (INIS)

    This project is designed to demonstrate in situ bioremediation of groundwater and sediment contaminated with chlorinated solvents. Indigenous microorganisms were stimulated to degrade TCE, PCE and their daughter products in situ by addition of nutrients to the contaminated zone. In situ biodegradation is a highly attractive technology for remediation because contaminants are destroyed, not simply moved to another location or immobilized, thus decreasing costs, risks, and time, while increasing efficiency and public and regulatory acceptability. Bioremediation has been found to be among the least costly technologies in applications where it will work (Radian 1989). Subsurface soils and water adjacent to an abandoned process sewer line at the SRS have been found to have elevated levels of TCE (Marine and Bledsoe 1984). This area of subsurface and groundwater contamination is the focus of a current integrated demonstration of new remediation technologies utilizing horizontal wells. Bioremediation has the potential to enhance the performance of in situ air stripping as well as offering stand-alone remediation of this and other contaminated sites (Looney et al. 1991). Horizontal wells could also be used to enhance the recovery of groundwater contaminants for bioreactor conversions from deep or inaccessible areas (e.g., under buildings) and to enhance the distribution of nutrient or microbe additions in an in situ bioremediation

  15. Pattern selection in a horizontally vibrated container

    International Nuclear Information System (INIS)

    We present results of an experimental and numerical investigation of the patterns realized by surface waves within an open rectangular container subjected to horizontal vibrations at frequencies of 40–100 Hz. The first instability exhibited by the primary harmonic wave field is subharmonic, and may be identified with the cross-wave instability often seen in wave tank experiments. We show that, contrary to common theoretical and experimental assumptions, and despite their name, these subharmonic waves are not oriented crosswise, but at an intermediate angle with respect to the axis of vibration. Hence, the pattern selection problem for horizontally forced Faraday waves is more complex than has previously been assumed. We establish the robustness of this obliquely oriented surface wave pattern by varying the forcing frequency and amplitude, the fluid viscosity, the fluid depth, and the boundary conditions. Previous work on cross-waves is reviewed and discussed in relation to the current results. Finally, numerical simulations using a reduced model with an appropriate forcing term are used to support the generality of the experimental observations. (paper)

    A former natural gas processing site with total petroleum hydrocarbons (TPH) and benzene, toluene, ethylbenzene, and xylene (BTEX) impacts in both soil and groundwater was partially excavated to remove 2,400 cubic yards of impacted soil. However, due to active natural gas pipelines within the impacted footprint, excavation was discontinued and an area of impacted soil containing maximum concentrations of 5,000 mg/kg gasoline-range organics (GRO), 8,600 mg/kg diesel-range organics (DRO), and 130 mg/kg motor oil-range organics (ORO). Groundwater was impacted with concentrations up to 2,300 μg/L GRO and 4,200 μg/L DRO remained in place. Taking advantage of the open excavation, horizontal-screened piping was placed in the backfill to deliver air for bioventing, which resulted in successful remediation of soil in a physically inaccessible area. The combined use of excavation of the source area, bioventing of surrounding inaccessible soil, and biosparging of the groundwater and smear zone resulted in nearing a no-further-action status at the site. The sustainable bioventing system consisted of one 3-HP blower and eight horizontal air injection wells. Five dual-depth nested vapor monitoring points (VMPs) were installed at 5 feet and 10 feet below ground surface as part of the monitoring system for human health and system performance. The bioventing system operated for one year followed by a three-month rebound test. During the one-year operation, air flow was periodically adjusted to maximize removal of volatile organic compounds (VOCs) from the vent wells with elevated photo-ionization detector readings. After the bioventing successfully remediated the inaccessible impacted soil, the biosparging system incorporated the pre-existing bioventing unit with an upgraded 5-HP blower and three vertical biosparging wells to biodegrade dissolved phase impacts in the groundwater. The subsequent monitoring system includes the VMPs, the air injection wells, and four groundwater

    Full Text Available A pilot anaerobic reactor was installed to remove the organic load of wastewater from dairy industry. It uses a bacterial inoculum previously acclimated to the substrate. It was disposed horizontally and filled with pieces of polyethylene terephthalate (PET, from plastic bottles. The reactor was operated at room temperature, during 100 days, in three phases: 1 the reactor was stabilized with volumetric organic load from 0.013 to 0.500 kg/day.m³; 2 the hydraulic retention time was of 1 day and the volumetric organic load of 3 kg/day.m³; 3 the volumetric organic load was incremented from 4 to 6.6 kg/day.m³ and the hydraulic retention time was 1 day. Organic material removal efficiencies was of 85%, and approximately 75% were obtained in the second and third phase, respectively. The Y value was 0.15, indicating that 0.15 kg of biomass were generated by kg of QDO supplied to the reactor. Finally, the biomass generated inside the reactor was analyzed, obtaining a value of 18868 mg/L, which is a higher value than those of conventional systems.

    Full Text Available Purpose.Horizontal settlers are one of the most important elements in the technological scheme of water purification. Their use is associated with the possibility to pass a sufficiently large volume of water. The important task at the stage of their designing is evaluating of their effectiveness. Calculation of the efficiency of the settler can be made by mathematical modeling. Empirical, analytical models and techniques that are currently used to solve the problem, do not allow to take into account the shape of the sump and various design features that significantly affects the loyalty to a decision on the choice of the size of the settling tank and its design features. The use of analytical models is limited only to one-dimensional solutions, does not allow accounting for nonuniform velocity field of the flow in the settler. The use of advanced turbulence models for the calculation of the hydrodynamics in the settler complex forms now requires very powerful computers. In addition, the calculation of one variant of the settler may last for dozens of hours. The aim of the paper is to build a numerical model to evaluate the effectiveness of horizontal settling tank modified design. Methodology. Numerical models are based on: 1 equation of potential flow; 2 equation of inviscid fluid vortex flow; 3 equation of viscous fluid dynamics; 4 mass transfer equation. For numerical simulation the finite difference schemes are used. The numerical calculation is carried out on a rectangular grid. For the formation of the computational domain markers are used. Findings.The models allow calculating the clarification process in the settler with different form and different configuration of baffles. Originality. A new approach to investigate the mass transfer process in horizontal settler was proposed. This approach is based on the developed CFD models. Three fluid dynamics models were used for the numerical investigation of flows and waste waters purification

  20. Passive magnetic bearing for a horizontal shaft

    Energy Technology Data Exchange (ETDEWEB)

    Post, Richard F.

    2003-12-02

    A passive magnetic bearing is composed of a levitation element and a restorative element. The levitation element is composed of a pair of stationary arcuate ferromagnetic segments located within an annular radial-field magnet array. The magnet array is attached to the inner circumference of a hollow shaft end. An attractive force between the arcuate segments and the magnet array acts vertically to levitate the shaft, and also in a horizontal transverse direction to center the shaft. The restorative element is comprised of an annular Halbach array of magnets and a stationary annular circuit array located within the Halbach array. The Halbach array is attached to the inner circumference of the hollow shaft end. A repulsive force between the Halbach array and the circuit array increases inversely to the radial space between them, and thus acts to restore the shaft to its equilibrium axis of rotation when it is displaced therefrom.

    We report on HST/WFPC2 U,V and far-ultraviolet observations of two Galactic Globular Clusters (GGCs), NGC 6205 = M13 and NGC 6093 = M80. Both of these clusters have horizontal-branch (HB) tails that extend to the helium-burning main sequence, with the hottest stars reaching theoretical effective temperatures above 35,000 K. In both clusters, groups of stars are found to be separated by narrow gaps along the blue HB sequence. These gaps appear at similar locations in the color-magnitude diagrams of the two clusters. While stochastic effects may give rise to variations in the color distribution along the HB, the coincidence of gaps in different clusters effectively rules this out as the primary cause. The comparison among the clusters strongly suggests that there are separate physical processes operating during the earlier red-giant phase of evolution to produce mass loss.

    This study involved the numerical investigation of conjugate natural convection between two horizontal eccentric cylinders. Both cylinders were considered to be isothermal with only the inner cylinder having a finite wall thickness. The momentum and energy equations were discretized using finite volume method and solved by employing SIMPLER algorithm. Numerical results were presented for various solid-fluid conductivity ratios (KR) and various values of eccentricities in different thickness of inner cylinder wall and also for different angular positions of inner cylinder. From the results, it was observed that in an eccentric case, and for KR 10 value caused an increase in overline{{K_{eq} }} . It was also concluded that in any angular position of inner cylinder, the value of overline{{K_{eq} }} increased with increase in the eccentricity.

    Full Text Available Horizontal gene transfer (HGT plays an important role in the evolution of life on the Earth. This view is supported by numerous occasions of HGT that are recorded in the genomes of all three domains of living organisms. HGT-mediated rapid evolution is especially noticeable among the Bacteria, which demonstrate formidable adaptability in the face of recent environmental changes imposed by human activities, such as the use of antibiotics, industrial contamination, and intensive agriculture. At the heart of the HGT-driven bacterial evolution and adaptation are highly sophisticated natural genetic engineering tools in the form of a variety of mobile genetic elements (MGEs. The main aim of this review is to give a brief account of the occurrence and diversity of MGEs in natural ecosystems and of the environmental factors that may affect MGE-mediated HGT.

    Hydrodynamic characters on a horizontal, thin, rigid plate located beneath the free surface are numerically investigated. Assuming a linear, time-harmonic potential flow and utilizing Green identity, the governing Laplace equation can be simplified into Fredholm integral equation ofthe second kind. Supposing linear-order discontinuous elements along intersecting vertical boundaries, and by use of the boundary element method, numerical solution about source strength distribution on the plate can be changed into a series of algebraic equations. The 3D Green function is introduced to set up the integral equations, and the GMRES solver is performed for solving the large dense linear system of equations. The added-mass, damping force and exciting force are evaluated directly from the equations. It is found that the added-mass coefficient becomes negative for a range of frequencies when the plate is sufficiently close to the free surface.

  6. Blue Horizontal Branch Stars in M92

    1997-01-01

    We have analyzed high dispersion and high precision spectra of 5 blue horizontal branch stars in the globular cluster M92 to establish that the projected rotational velocity for these stars ranges from 15 to 40 \\kms. This is larger than that expected based on the rotation of their main sequence progenitors, the spin down of rotation with age, and the conservation of angular momentum. Possible explanations include a rapidly rotating stellar core. An abundance analysis of these spectra of these blue HB stars in M92 yields the same results as have been obtained from the giants in this cluster. There is a hint of a trend of higher abundance as the projected surface rotational velocity increases, which could be chance and requires confirmation.

    2015-05-01

    Full Text Available The Halobacteria are a well-studied archaeal class and numerous investigations are showing how their diversity is distributed amongst genomes and geographic locations. Evidence indicates that recombination between species continuously facilitates the arrival of new genes, and within species, it is frequent enough to spread acquired genes amongst all individuals in the population. To create permanent independent diversity and generate new species, barriers to recombination are probably required. The data support an interpretation that rates of evolution (e.g., horizontal gene transfer and mutation are faster at creating geographically localized variation than dispersal and invasion are at homogenizing genetic differences between locations. Therefore, we suggest that recurrent episodes of dispersal followed by variable periods of endemism break the homogenizing forces of intrapopulation recombination and that this process might be the principal stimulus leading to divergence and speciation in Halobacteria.

    We review three main results of our recent study: We show that a proper treatment of the tidal interaction prior to the onset of the common envelope (CE) leads to an enhance mass loss. This might increase the survivability of planets and brown dwarfs that enter a CE phase. From the distribution of planets around main sequence stars, we conclude that around many sdB/sdO stars more than one planet might be present. One of these might have a close orbit and the others at about orbital periods of years or more. We show that the intense ionizing flux of the extreme horizontal branch star might evaporate large quantities of a very close surviving substellar object. Balmer emission lines from the evaporated gas can be detected via their Doppler shifts.

  12. Mixed convection flow past a horizontal plate

    Savić Lj.

    2005-01-01

    Full Text Available The mixed convection flow past a horizontal plate being aligned through a small angle of attack to a uniform free stream will be considered in the limit of large Reynolds number and small Richardson number. Even a small angle of inclination of the wake is sufficient for the buoyancy force to accelerate the flow in the wake which causes a velocity overshoot in the wake. Moreover a hydrostatic pressure difference across the wake induces a correction to the potential flow which influences the inclination of the wake. Thus the wake and the correction of the potential flow have to be determined simultaneously. However, it turns out that solutions exist only if the angle of attack is sufficiently large. Solutions are computed numerically and the influence of the buoyancy on the lift coefficient is determined.

    In this paper the capability of the five- and six-equation models of the simulation code APROS to simulate the behaviour of the horizontal steam generator is discussed. Different nodalizations are used in the modelling and the results of the stationary state runs are compared. Exactly the same nodalizations have been created for the five- and six-equation models. The main simulation results studied in this paper are void fraction and mass flow distributions in the secondary side of the steam generator. It was found that quite a large number of simulation volumes is required to simulate the distributions with a reasonable accuracy. The simulation results of the different models are presented and their validity is discussed. (orig.). 4 refs.

  14. Physical Parameters of Hot Horizontal-Branch Stars in NGC 6752: Deep Mixing and Radiative Levitation

    Atmospheric parameters (T(sub eff), log g and log n(sub He)/n(sub H-dot)) are derived for 42 hot horizontal branch (HB) stars in the globular cluster NGC 6752. For 19 stars Mg II and Fe II lines are detected indicating an iron enrichment by a factor 50 on average with respect to the cluster abundance whereas the magnesium abundances are consistent with the cluster metallicity. This finding adds to the growing evidence that radiative levitation plays a significant role in determining the physical parameters of blue HB stars. Indeed, we find that iron enrichment can explain part, but not all, of the problem of anomalously low gravities along the blue HB. Thus the physical parameters of horizontal branch stars hotter than about 11,500 K in NGC 6752, as derived in this paper, are best explained by a combination of helium mixing and radiative levitation effects.

  15. In situ bioremediation via horizontal wells

    International Nuclear Information System (INIS)

    The test consisted of methane mixed with air into the contaminated aquifer via a horizontal well and extraction from the vadose zone via a parallel horizontal well. This configuration has the advantage of simultaneously stimulating methanotrophic activity in both the groundwater and vadose zone, and inhibiting spread of the contaminant plume. Groundwater was monitored biweekly from 13 wells for a variety of chemical and microbiological parameters. Groundwater from wells in affected areas showed increases in methanotrophs of more than 1 order of magnitude every 2 weeks for several weeks after 1% methane-in-air injection was started. Some wells had increases as much as 7 orders of magnitude. Simultaneous with the increase in methanotrophs was a decrease in water and soil gas concentrations of trichloroethylene (TCE) and tetrachloroethane (PCE). Two wells declined in TCE/PCE concentration in the water by more than 90% to below 2 ppb. All of the wells in the affected zone showed significant decreases in contaminants in less than one month. Chloride concentrations in the water were inversely correlated with TCE/PCE concentration. Four of five vadose zone piezometers declined from concentration as high as 10,000 ppm to less than 5 ppm in less than 6 weeks. The fifth cluster also declined by more than 95%. After only three months on injection, a decline in TCE/PCE in the sediment of more than 30% was also observed, with TCE/PCE being undetectable in most sediments at the end of the 14-month test. Gene probes and direct isolation from the water and sediment revealed that the right types of methanotrophs were being stimulated and that isolates could degrade TCE at a high rate

    through horizontal openings. Two cases of full-scale measurements of buoyancy driven natural ventilation through horizontal openings are performed: one horizontal opening and one horizontal opening combined with one vertical opening. For the case of one horizontal opening, the measurements are made...... for opening ratios L/D range from 0.027 to 4.455. The basic nature of air flow through the openings, including air flow rate, air velocity, temperature difference between the rooms and the dimensions of the horizontal openings, are measured. Smoke visualizations show that the air flow patterns are highly...... transient, unstable and complex, and the air flow rates oscillate with time. Correlations between the Froude number Fr and the opening ratio L/D are obtained, which is reasonable agreement with Epstein's formula derived from brine-water measurements, but the obtained Fr values show considerable deviations...

    Using the data observed by the Solar Optical Telescope/Spectro-Polarimeter aboard the Hinode satellite, the horizontal and vertical fields are derived from the wavelength-integrated measures of Zeeman-induced linear and circular polarizations. The quiet intranetwork regions are pervaded by horizontal magnetic elements. We categorize the horizontal intranetwork magnetic elements into two types: one is the non-isolated element which is accompanied by the vertical magnetic elements during its evolution; another is the isolated element which is not accompanied by the vertical magnetic elements. We identify 446 horizontal intranetwork magnetic elements, among them 87 elements are isolated and 359 are non-isolated. Quantitative measurements reveal that the isolated elements have relatively weaker horizontal magnetic fields, almost equal size, and shorter lifetime comparing with the non-isolated elements. Most non-isolated horizontal intranetwork magnetic elements are identified to associate with the emergence of Om...

  19. Mg spin affects adenosinetriphosphate activity

    Tulub, Alexander A

    2009-01-01

    The Schlegel-Frisch ab initio molecular dynamics (ADMP) (DFT:B3LYP), T = 310 K, is used to study complexation between adenosinetriphosphate (ATP), ATP subsystem, and magnesium cofactor [Mg(H2O)6]2+, Mg subsystem, in a water pool, modeled with 78 water molecules, in singlet (S) and triplet (T) states. The computations prove that the way of ATP cleavage is governed by the electron spin of Mg. In the S state Mg prefers chelation of \\gamma-\\beta-phosphate oxygens (O1-O2), whereas in the T state it chelates \\beta-\\alpha-phosphate oxygens (O2-O3) or produces a single-bonded intermediate. Unlike the chelates, which initiate ionic reaction paths, the single-bonded intermediate starts off a free-radical path of ATP cleavage, yielding a highly reactive adenosinemonophosphate ion-radical, .AMP-, earlier observed in the CIDNP (Chemically Induced Dynamic Nuclear Polarization) experiment (A.A. Tulub, 2006). The free-radical path is highly sensitive to Mg nuclear spin, which through a hyperfine interaction favors the produc...

    Full Text Available A large number of studies have been devoted to the effects of horizontal mergers on competition. This survey intends to review some selected studies about the effects of competition on horizontal mergers with a special attention given the horizontal integration. One of the important results obtained from this literature survey is that the findings of many researches have largely been controversial due to the different approaches and the time periods used in their studies. In these studies, even though it has been proved that horizontal mergers have negative effects on competition, it is not possible to make any precise comment on the dimension of this effect.

    Mass measurements with a relative precision of better than $1.5 \\times 10^{-8}$ were performed on $^{22}$Mg and its reaction partners $^{21}$Na and $^{22}$Na with the ISOLTRAP Penning trap mass spectrometer at CERN, yielding the mass excesses $D(^{22}$Mg) = -399.92(27) keV, $D(^{21}$Na) = -2184.71(21) keV, and $D(^{22}$Na) = -5181.56(16) keV. The importance of these results is twofold. First, a comparative half-life ($Ft$ value)has been obtained for the superallowed $\\beta$-decay of $^{22}$Mg to further test the conserved-vector-current hypothesis. Second, the resonance energy for the $^{21}$Na proton capture reaction has been independently determined, allowing direct comparisons of observable $\\gamma$-radiation in nova explosions with the yield expected from models.

  4. Demonstration of a utility industry horizontal drilling system: Horizontal well AMH-5 installation report

    International Nuclear Information System (INIS)

    The Department of Energy's Office of Technology Development initiated an integrated demonstration of innovative technologies and systems for cleanup of VOCs in soils and groundwater at the Savannah River Site (SRS) in 1989. The overall goal of the program is demonstration of multiple technologies and systems in the fields of drilling, characterization, monitoring, and remediation at a single test bed. Innovative technologies are compared to one another and to baseline technologies in terms of technical performance and cost effectiveness. Transfer of successfully demonstrated technologies and systems to DOE environmental restoration organizations, to other government agencies, and to industry is a critical part of the program. Directional drilling has been shown to be a successful technique for enhancing access to the subsurface, thus improving remediation systems, especially remediation systems which perform in situ. Demonstration of an innovative directional drilling system at the Integrated Demonstration Site at the SRS, was initiated in June of 1992. The directional drilling system was designed to install an in situ remediation system. The drilling system is an experimental compaction/dry drilling technique developed by Charles Machine Works (Ditch Witch reg-sign) of Perry, Oklahoma. A horizontal well was installed in the M Area of the SRS below and parallel to an abandoned tile process sewer line. The installation of the horizontal well was a two-part process. Part one consisted of drilling the borehole, and part two was the horizontal well completion

    2016-04-01

    The Boussinesq equation is a dynamical equation for the free surface of saturated subsurface flows over an impervious bed. Boussinesq equation is non-linear. The non-linearity comes from the reduction of the dimensionality of the problem: The flow is assumed to be vertically homogeneous, therefore the flow rate through a cross section of the flow is proportional to the free surface height times the hydraulic gradient, which is assumed to be equal to the slope of the free surface. In the present work we consider the case of the subsurface flow with horizontal bed. This is a case with an infinite Henderson and Wooding parameter, that is, it is the limiting case where the non-linear term is present in the Boussinesq equation while the linear spatial derivative term vanishes. Nonetheless, no analogue of the kinematic wave exists in this case as there is no exact solution for the build-up phase. Neither is there an exact recession-phase solution that holds in early times, as the Boussinesq separable solution is actually an asymptotic solution for large times. We construct approximate solutions for the horizontal aquifer which utilize directly the dynamical content of the non-linear Boussinesq equation. The approximate character of the solution lies in the fact that we start with a pre-supposed form for the solution, an educated guess, based on the nature of the initial condition as well as empirical observations from the numerical solution of the problem. The forms we shall use are power series of the location variable x along the bed with time-dependent coefficients. The series are not necessarily analytic. The boundary conditions are incorporated in the structure of the series from the beginning. The time-dependent coefficients are then determined by applying the Boussinesq equation and its spatial derivatives at the end-points of the aquifer. The forms are chosen also on the basis of their solubility; we would like to be able to construct explicitly the approximate

    Drag reduction and/or speed augmentation of marine vehicles by means of supercavitation is a topic of great interest. During the initial launch of a supercavitating vehicle, an artificial supercavity is required until the vehicle can reach conditions at which a natural supercavity can be sustained. Previous studies at Saint Anthony Falls Laboratory (SAFL) focused on the behavior of ventilated supercavities in steady horizontal flows. In open waters, vehicles can encounter unsteady flows, especially when traveling under waves. A study has been carried out at SAFL to investigate the effects of unsteady flow on axisymmetric supercavities. An attempt is made to duplicate sea states seen in open waters. In an effort to track cavity dimensions throughout a wave cycle, an automated cavity tracking script has been developed. Using a high speed camera and the proper software, it is possible to synchronize cavity dimensions with pressure measurements taken inside the cavity. Results regarding supercavity shape, ventilation demand, cavitation parameters and closure methods are presented. It was found that flow unsteadiness caused a decrease in the overall length of the supercavity while having only a minimal effect on the maximum diameter. The supercavity volume varied with cavitation number and a possible relationship between the two is being explored. (Supported by ONR)

  7. Yaw dynamics of horizontal axis wind turbines

    Designers of a horizontal axis wind turbine yaw mechanism are faced with a difficult decision. They know that if they elect to use a yaw- controlled rotor then the system will suffer increased initial cost and increased inherent maintenance and reliability problems. On the other hand, if they elect to allow the rotor to freely yaw they known they will have to account for unknown and random, though bounded, yaw rates. They will have a higher-risk design to trade-off against the potential for cost savings and reliability improvement. The risk of a yaw-free system could be minimized if methods were available for analyzing and understanding yaw behavior. The complexity of yaw behavior has, until recently, discouraged engineers from developing a complete yaw analysis method. The objectives of this work are to (1) provide a fundamental understanding of free-yaw mechanics and the design concepts most effective at eliminating yaw problems, and (2) provide tested design tools and guidelines for use by free-yaw wind systems manufacturers. The emphasis is on developing practical and sufficiently accurate design methods.

  8. Horizontal visibility graphs from integer sequences

    2016-09-01

    The horizontal visibility graph (HVG) is a graph-theoretical representation of a time series and builds a bridge between dynamical systems and graph theory. In recent years this representation has been used to describe and theoretically compare different types of dynamics and has been applied to characterize empirical signals, by extracting topological features from the associated HVGs which have shown to be informative on the class of dynamics. Among some other measures, it has been shown that the degree distribution of these graphs is a very informative feature that encapsulates nontrivial information of the series's generative dynamics. In particular, the HVG associated to a bi-infinite real-valued series of independent and identically distributed random variables is a universal exponential law P(k)=(1/3){(2/3)}k-2, independent of the series marginal distribution. Most of the current applications have however only addressed real-valued time series, as no exact results are known for the topological properties of HVGs associated to integer-valued series. In this paper we explore this latter situation and address univariate time series where each variable can only take a finite number n of consecutive integer values. We are able to construct an explicit formula for the parametric degree distribution {P}n(k), which we prove to converge to the continuous case for large n and deviates otherwise. A few applications are then considered.

    A numerical model was proposed to simulate the solidification process of an outer shell of work roll made by the horizontal centrifugal casting technique. Shallow water model was adopted to solve the 2D average flow dynamics of melt spreading and the average temperature distribution inside the centrifugal casting mould by considering the centrifugal force, Coriolis force, viscous force due to zero velocity on the mould wall, gravity, and energy transport by the flow. Additionally, a 1D sub-model was implemented to consider the heat transfer in the radial direction from the solidifying shell to the mould. The solidification front was tracked by fulfilling the Stefan condition. Radiative and convective heat losses were included from both, the free liquid surface and the outer wall of the mould. Several cases were simulated with the following assumed initial conditions: constant height of the liquid metal (10, 20, and 30 mm), uniform temperature of the free liquid surface (1755 K). The simulation results have shown that while the solidification front remained rather flat, the free surface was disturbed by waves. The amplitude of waves increased with the liquid height. Free surface waves diminished as the solidification proceeded.

  10. Horizontal Shear Wave Imaging of Large Optics

    2007-09-05

    When complete the National Ignition Facility (NIF) will be the world's largest and most energetic laser and will be capable of achieving for the first time fusion ignition in the laboratory. Detecting optics features within the laser beamlines and sizing them at diameters of 0.1 mm to 10 mm allows timely decisions concerning refurbishment and will help with the routine operation of the system. Horizontally polarized shear waves at 10 MHz were shown to accurately detect, locate, and size features created by laser operations from 0.5 mm to 8 mm by placing sensors at the edge of the optic. The shear wave technique utilizes highly directed beams. The outer edge of an optic can be covered with shear wave transducers on four sides. Each transducer sends a pulse into the optic and any damage reflects the pulse back to the transmitter. The transducers are multiplexed, and the collected time waveforms are enveloped and replicated across the width of the element. Multiplying the data sets from four directions produces a map of reflected amplitude to the fourth power, which images the surface of the optic. Surface area can be measured directly from the image, and maximum depth was shown to be correlated to maximum amplitude of the reflected waveform.

  11. Horizontal transfer of diatomaceous earth and botanical insecticides in the common bed bug, Cimex lectularius L.; hemiptera: cimicidae.

    Full Text Available BACKGROUND: Horizontal transfer of insecticide occurs when insects contact or ingest an insecticide, return to an aggregation or a nest, and transfer the insecticide to other conspecific insects through contact. This phenomenon has been reported in a number of insects including social insects, however it has not been reported in bed bugs. Since horizontal transfer can facilitate the spread of insecticide into hard to reach spaces, it could contribute greatly to the management of these public health pests. METHODOLOGY/RESULTS: To demonstrate horizontal transfer of diatomaceous earth and botanical insecticides in C. lectularius, an exposed (donor bed bug, following a 10-minute acquisition period, was placed with unexposed (recipient bed bugs. Mortality data clearly demonstrates that diatomaceous earth (DE 51 was actively transferred from a single exposed bug to unexposed bugs in a concentration dependent manner. LC50 values varied from 24.4 mg at 48 h to 5.1 mg at 216 h when a single exposed bed bug was placed with 5 unexposed bed bugs. LT50 values also exhibited a concentration response. LT50 values varied from 1.8 days to 8.4 days when a 'donor' bug exposed to 20 and 5 mg of dust respectively was placed with 5 'recipient' bugs. Dust was also actively transferred from adult bed bugs to the nymphs. In addition we observed horizontal transfer of botanical insecticides including neem, ryania, and rotenone to varying degrees. CONCLUSION/SIGNIFICANCE: Our data clearly demonstrate horizontal transfer of diatomaceous earth and botanical insecticides in the common bed bug, C. lectularius. Use of a fluorescent dust provided visual confirmation that contaminated bed bugs transfer dust to untreated bed bugs in harborage. This result is important because bedbugs live in hard-to-reach places and interaction between conspecifics can be exploited for delivery and dissemination of management products directed at this public health pest.

    The present invention provides a steerable vertical to horizontal energy transducer for mobile robots that less complex and requires less power than two degree of freedom tilt mechanisms. The present invention comprises an end effector that, when mounted with a hopping actuator, translates along axis (typically vertical) actuation into combined vertical and horizontal motion. The end effector, or foot, mounts with an end of the actuator that moves toward the support surface (typically a floor or the earth). The foot is shaped so that the first contact with the support surface is off the axis of the actuator. Off-axis contact with the support surface generates an on-axis force (typically resulting in vertical motion) and a moment orthogonal to the axis. The moment initiates a horizontal tumbling motion, and tilts the actuator so that its axis is oriented with a horizontal component and continued actuation generates both vertical and horizontal force.

    We used FLAMES+GIRAFFE (Medusa mode) at the VLT to obtain moderately high resolution spectra for 30 red horizontal branch (RHB) stars, 4 RR Lyrae variables, and 17 blue horizontal branch (BHB) stars in the low-concentration, moderately metal-rich globular cluster NGC6723 ([Fe/H]=-1.22+/-0.08 from our present sample). The spectra were optimized to derive O and Na abundances. In addition, we obtained abundances for other elements, including N, Fe, Mg, Ca, Ni, and Ba. We used these data to discuss the evidence of a connection between the distribution of stars along the horizontal branch (HB) and the multiple populations that are typically present in globular clusters. We found that all RHB and most (13 out of 17) BHB stars are O-rich, Na-poor, and N-poor; these stars probably belong to the first stellar generation in this cluster. Only the four warmest observed stars are (moderately) O-poor, Na-rich, and N-rich, and they probably belong to the second generation. While our sample is not fully representative of th...

  14. Horizontal versus familial transmission of Helicobacter pylori.

    Full Text Available Transmission of Helicobacter pylori is thought to occur mainly during childhood, and predominantly within families. However, due to the difficulty of obtaining H. pylori isolates from large population samples and to the extensive genetic diversity between isolates, the transmission and spread of H. pylori remain poorly understood. We studied the genetic relationships of H. pylori isolated from 52 individuals of two large families living in a rural community in South Africa and from 43 individuals of 11 families living in urban settings in the United Kingdom, the United States, Korea, and Colombia. A 3,406 bp multilocus sequence haplotype was determined for a total of 142 H. pylori isolates. Isolates were assigned to biogeographic populations, and recent transmission was measured as the occurrence of non-unique isolates, i.e., isolates whose sequences were identical to those of other isolates. Members of urban families were almost always infected with isolates from the biogeographic population that is common in their location. Non-unique isolates were frequent in urban families, consistent with familial transmission between parents and children or between siblings. In contrast, the diversity of H. pylori in the South African families was much more extensive, and four distinct biogeographic populations circulated in this area. Non-unique isolates were less frequent in South African families, and there was no significant correlation between kinship and similarity of H. pylori sequences. However, individuals who lived in the same household did have an increased probability of carrying the same non-unique isolates of H. pylori, independent of kinship. We conclude that patterns of spread of H. pylori under conditions of high prevalence, such as the rural South African families, differ from those in developed countries. Horizontal transmission occurs frequently between persons who do not belong to a core family, blurring the pattern of familial

  15. Horizontal gene transfer from Agrobacterium to plants

    2014-08-01

    Full Text Available Most genetic engineering of plants uses Agrobacterium mediated transformation to introduce novel gene content. In nature, insertion of T-DNA in the plant genome and its subsequent transfer via sexual reproduction has been shown in several species in the genera Nicotiana and Linaria. In these natural examples of horizontal gene transfer from Agrobacterium to plants, the T-DNA donor is assumed to be a mikimopine strain of A.rhizogenes. A sequence homologous to the T-DNA of the Ri plasmid of Agrobacterium rhizogenes was found in the genome of untransformed Nicotiana glauca about 30 years ago, and was named cellular T-DNA (cT-DNA. It represents an imperfect inverted repeat and contains homologues of several T-DNA oncogenes (NgrolB, NgrolC, NgORF13, NgORF14 and an opine synthesis gene (Ngmis. A similar cT-DNA has also been found in other species of the genus Nicotiana. These presumably ancient homologues of T-DNA genes are still expressed, indicating that they may play a role in the evolution of these plants. Recently T-DNA has been detected and characterized in Linaria vulgaris and L. dalmatica. In Linaria vulgaris the cT-DNA is present in two copies and organized as a tandem imperfect direct repeat, containing LvORF2, LvORF3, LvORF8, LvrolA, LvrolB, LvrolC, LvORF13, LvORF14, and the Lvmis genes. All L. vulgaris and L. dalmatica plants screened contained the same T-DNA oncogenes and the mis gene. Evidence suggests that there were several independent T-DNA integration events into the genomes of these plant genera. We speculate that ancient plants transformed by A. rhizogenes might have acquired a selective advantage in competition with the parental species. Thus, the events of T-DNA insertion in the plant genome might have affected their evolution, resulting in the creation of new plant species. In this review we focus on the structure and functions of cT-DNA in Linaria and Nicotiana and discuss their possible evolutionary role.

  16. Computational studies of horizontal axis wind turbines

    Science.gov (United States)

    Xu, Guanpeng

    A numerical technique has been developed for efficiently simulating fully three-dimensional viscous fluid flow around horizontal axis wind turbines (HAWT) using a zonal approach. The flow field is viewed as a combination of viscous regions, inviscid regions and vortices. The method solves the costly unsteady Reynolds averaged Navier-Stokes (RANS) equations only in the viscous region around the turbine blades. It solves the full potential equation in the inviscid region where flow is irrotational and isentropic. The tip vortices are simulated using a Lagrangean approach, thus removing the need to accurately resolve them on a fine grid. The hybrid method is shown to provide good results with modest CPU resources. A full Navier-Stokes based methodology has also been developed for modeling wind turbines at high wind conditions where extensive stall may occur. An overset grid based version that can model rotor-tower interactions has been developed. Finally, a blade element theory based methodology has been developed for the purpose of developing improved tip loss models and stall delay models. The effects of turbulence are simulated using a zero equation eddy viscosity model, or a one equation Spalart-Allmaras model. Two transition models, one based on the Eppler's criterion, and the other based on Michel's criterion, have been developed and tested. The hybrid method has been extensively validated for axial wind conditions for three rotors---NREL Phase II, Phase III, and Phase VI configurations. A limited set of calculations has been done for rotors operating under yaw conditions. Preliminary simulations have also been carried out to assess the effects of the tower wake on the rotor. In most of these cases, satisfactory agreement has been obtained with measurements. Using the numerical results from present methodologies as a guide, Prandtl's tip loss model and Corrigan's stall delay model were correlated with present calculations. An improved tip loss model has been

    1991-12-09

    This paper reports on the MWD dual processing resistivity (DPR) measurements and modelling which helped steer a horizontal well through a thin oil zone to avoid a nearby oil/water contact. The horizontal well came on-line flowing 380 bo/d with no water production. Offset vertical wells produce an average of 33 bo/d with an 83% saltwater cut. Until recently, horizontal drilling efforts have been focused on thick reservoirs in which the stratigraphic position of the well bore within the target formation was not critical. Navigation through much thinner reservoirs is now possible with a technique that uses an electromagnetic propagation resistivity tool.

    As an example of the La-Mg-Y system, the method how to set up the thermodynamic model of individual phases was introduced in the process of thermodynamic optimization. The solution phases (liquid, body-centered cubic,face-centered cubic, hexagonal close-packed and double hexagonal close-packed) were modeled with the Redlich-Kister equation. The compound energy model has been used to describe the thermodynamic functions of the intermetallic compounds in the La-Mg-Y systems. The compounds Mg2Y, Mg24Y5, Mg12La, Mg17La2, Mg41La5, Mg3La and Mg2La in the La-Mg-Y system were treated as the formulae (Mg, Y)2(La,Mg, Y), Mg24(La,Mg, Y)4Y, Mg12(La, Y), Mg17(La, Y)2,Mg41(La,Y)5, Mg3(La,Mg,Y) and Mg2(La,Y), respectively. A model (La,Mg,Y)0.5(La,Mg,Y)0.5 was applied to describe the compound MgM formed by MgLa and MgY in order to cope with the order-disorder transition between body-centered cubic solution (A2) and MgM with CsCl-type structure (B2) in the La-Mg-Y system. The Gibbs energies of individual phases were optimized in the La-Mg, La-Y and La-Mg-Y systems by CALPHAD technique. The projection of the liquidus surfaces for the La-Mg-Y system was predicted. The Mg-based alloys database including 36 binary and 15 ternary systems formed by Mg, Al, Cu, Ni, Mn, Zn and rare earth elements was set up in SGTE standard.

  20. Horizontal-vertical coupling for three dimensional laser cooling

    International Nuclear Information System (INIS)

    In order to achieve three dimensional crystal beam, laser cooling forces are required not only in the longitudinal direction, but also in the transverse directions. With the resonance coupling method, transverse temperature is transmitted into longitudinal direction, and we have already demonstrated the horizontal laser cooling experimentally. In the present paper, we will describe an approach to extend this result to three dimensional cooling. The vertical cooling requires that the horizontal oscillation couples with the vertical oscillation. For achieving horizontal-vertical coupling, the solenoid in electron beam cooling apparatus is utilized with an experiment (νx =2.07, νy=1.07). For various solenoidal magnetic fields from 0 to 100 Gauss, horizontal and vertical betatron tunes are measured by beam transfer function. For a certain region of the solenoidal magnetic field, these tunes are mixed up each other. (author)

    This paper describes a method to examine the relative merits of locations for horizontal wells in a naturally fractured shale gas basin. The methodology examines noncontrollable variables (existing reservoir pressure, pay-zone thickness, and success ratios) as well as controllable variables (gas price and drilling costs) to arrive at the profitability for a horizontal well project in a candidate area. An analysis of the expected monetary value (EMV) and a cash flow model are used to obtain a distribution of cash flow levels that yields a determination of whether a project is likely to succeed. Ranges of profitability for an unstimulated horizontal well are presented graphically. With this approach, the most likely areas for horizontal drilling to be economically and technically successful are identified easily and quickly.

    The interest in the application of heat pipes for heat transfer system is well known in industrial fields. Heat pipe uses the working fluid in containment as cylindrical shape tube. Vaporization occurs in evaporation section due to the heat input and vapor is transferred to condensation section. At the condensation area, the working fluid is condensed and immersed in the wick structure, which has highly porous media. The condensed working fluid returns to evaporator section by capillary wicking of wick structure. The driving force for working fluid is affected by capillary and gravitational force. The heat pipes for nuclear systems have been suggested as horizontal loop heat pipes for reactor core cooling system or vertical heat pipes for passive cooling for spent fuel. In the present research, preliminary tests of horizontal and vertical heat pipe were studied for its heat transfer performance. The main purpose of the research was the analysis of heat transfer behavior of heat pipe and the performance of heat transfer. The thermal performances of horizontal and vertical heat pipe were measured experimentally. Vertical heat pipe showed better performance compared to horizontal one, at high heat input region. The heat transfer coefficients of horizontal heat pipe were lower than vertical one because of gravitational force. Overall heat transfer coefficient of vertical heat pipes were enhanced to 28.5 % compared to the horizontal heat pipes. The horizontal heat pipes revealed high thermal resistance up to 54.3 % compared to vertical heat pipes. Therefore, vertical heat pipes analyzed better heat transfer performance than horizontal heat pipe.

At the condensation area, the working fluid is condensed and immersed in the wick structure, which has highly porous media. The condensed working fluid returns to evaporator section by capillary wicking of wick structure. The driving force for working fluid is affected by capillary and gravitational force. The heat pipes for nuclear systems have been suggested as horizontal loop heat pipes for reactor core cooling system or vertical heat pipes for passive cooling for spent fuel. In the present research, preliminary tests of horizontal and vertical heat pipe were studied for its heat transfer performance. The main purpose of the research was the analysis of heat transfer behavior of heat pipe and the performance of heat transfer. The thermal performances of horizontal and vertical heat pipe were measured experimentally. Vertical heat pipe showed better performance compared to horizontal one, at high heat input region. The heat transfer coefficients of horizontal heat pipe were lower than vertical one because of gravitational force. Overall heat transfer coefficient of vertical heat pipes were enhanced to 28.5 % compared to the horizontal heat pipes. The horizontal heat pipes revealed high thermal resistance up to 54.3 % compared to vertical heat pipes. Therefore, vertical heat pipes analyzed better heat transfer performance than horizontal heat pipe

    Full Text Available In the present work, Mg-rich Mg-Ni ultrafine powders were prepared through an arc plasma method. The phase components, microstructure, and hydrogen storage properties of the powders were carefully investigated. It is found that Mg2Ni and MgNi2 could be obtained directly from the vapor state reactions between Mg and Ni, depending on the local vapor content in the reaction chamber. A nanostructured MgH2 + Mg2NiH4 hydrogen storage composite could be generated after hydrogenation of the Mg-Ni ultrafine powders. After dehydrogenation, MgH2 and Mg2NiH4 decomposed into nanograined Mg and Mg2Ni, respectively. Thermogravimetry/differential scanning calorimetry (TG/DSC analyses showed that Mg2NiH4 phase may play a catalytic role in the dehydriding process of the hydrogenated Mg ultrafine particles.

  17. Isospin mixing in 24Mg

    International Nuclear Information System (INIS)

    We have used the #betta#-#betta# circular polarization (CP) correlation technique to measure the isospin-forbidden Fermi matrix element for the #betta#+ decay of 24Al to the 4+ T=1 state in 24Mg at E/sub x/=8.437 MeV. The 24Al activity was produced by bombarding a natural Mg target with 18 MeV protons. The #betta#-#betta# CP correlation was measured using a novel apparatus which featured good energy resolution in both the #betta# and #betta# arms. The CP sensitive #betta#-ray detector utilized a transmission-mode Compton polarimeter and a 12.7 cm x 15.2 cm NaI detector. The #betta# detector was a telescope with a 700 μm surface barrier detector and a 5.1 cm x 12.7 cm plastic scintillator. The #betta#-#betta# CP asymmetry A [defined by W(theta, t tilde) = 1 + t tilde v/c A tilde cos theta where t tilde is the photon helicity] was found to be A tilde = -0.145 +- 0.030. After applying a correction for feeding of the 8.437 MeV state from the analog state this value of A tilde corresponds to a charge dependent matrix element between the 9.5 MeV 4+T=1 and 8.4 MeV T=O levels of [+;O[H/sub CD/]4+;1>] = 106 +- 40 keV which is the largest matrix element of H/sub CD/ ever observed in #betta# decay. For comparison the charge dependent matrix element between the 9.5 MeV state and the 4.1 MeV 4+ state, previously measured in 24Na decays is only 5.4 +- 2.2 keV. Our exceptionally large value occurs because the 9.5 MeV T=1 and 8.4 MeV T=O states have very similar space and spin wavefunctions. This matrix element is consistent with predictions which ascribe the entire effect to Coulomb forces

  19. Cleanup/stimulation of a horizontal wellbore using propellants

    Rougeot, J.E.; Lauterbach, K.A.

    1993-01-01

    This report documents the stimulation/cleanup of a horizontal well bore (Wilson 25) using propellants. The Wilson 25 is a Bartlesville Sand well located in the Flatrock Field, Osage County, Oklahoma. The Wilson 25 was drilled to determine if horizontal drilling could be used as a means to economically recover primary oil that had been left in place in a mostly abandoned oil field because of the adverse effects of water coning. Pump testing of the Wilson 25 horizontal well bore before cleanup or stimulation produced 6 barrels of oil and .84 barrels of water per day. The high percentage of daily oil production to total daily fluid production indicated that the horizontal well bore had accessed potentially economical oil reserves if the fluid production rate could be increased by performing a cleanup/stimulation treatment. Propellants were selected as an inexpensive means to stimulate and cleanup the near well bore area in a uniform manner. The ignition of a propellant creates a large volume of gas which penetrates the formation, creating numerous short cracks through which hydrocarbons can travel into the well bore. More conventional stimulation/cleanup techniques were either significantly more expensive, less likely to treat uniformly, or could not be confined to the near well bore area. Three different propellant torpedo designs were tested with a total of 304' of horizontal well bore being shot and producible. The initial test shot caused 400' of the horizontal well bore to become plugged off, and subsequently it could not be production tested. The second and third test shots were production tested, with the oil production being increased 458% and 349%, respectively, on a per foot basis. The Wilson 25 results indicate that a propellant shot treatment is an economically viable means to cleanup/stimulate a horizontal well bore.

    In order to apply Stress Assisted Magnetization Reversal (SAMR) method to perpendicular magnetoresistive random access memory (p-MRAM) with magnetic tunnel junction (MTJ) using MgO (001) oriented barrier layer, multilayer of Ta/ Terfenol-D/ Mg/ MgO and Ta/ Terfenol-D/ MgO were prepared. While the MgO layer, deposited directly on the Terfenol-D layer, did not show (100) orientatin, very thin metallic Mg layer, deposited prior to the MgO deposition, was effective to attain MgO (100) orientation. The crystalline orientation was very weak without Mg, however, the multilayer with Mg showed very strong MgO(100) peak and the MgO orientation was shifted depending on the Mg thickness.

    @@ After the horizontal pendulum is used in ground-tilt measurement, its scaling has drawn great attentions from the people, because without a correct calibration of scale value, the observation is of little application significance. From the 1920's, quite a few scholars were engaged in the researches in this respect. And this question was satisfactorily solved until 1962 when Verbaandert (1962) invented the bulging plate, i.e., mercury-cup scaler.After further improvement, the V-M quartz horizontal pendulum tiltmeter was used globally in observation and great success was achieved (Melchior, 1966, 1978). In China, the quartz horizontal pendulum tiltmeter as well as the bulging-plate scaler were developed at the beginning of 1970's and then put into use after some improvements (ZHU and FENG, 1980). The successful observation by SQ quartz horizontal pendulum tiltmeter should be related not only to the excellent performance of horizontal pendulum, but also to its accurate calibration. The bulging plate plays an important role in calibration, because it is the critical component of scaler.

  2. Investigation of gravity waves using horizontally resolved radial velocity measurements

    Full Text Available The Middle Atmosphere Alomar Radar System (MAARSY on the island Andøya in Northern Norway (69.3° N, 16.0° E observes polar mesospheric summer echoes (PMSE. These echoes are used as tracers of atmospheric dynamics to investigate the horizontal wind variability at high temporal and spatial resolution. MAARSY has the capability of a pulse-to-pulse beam steering allowing for systematic scanning experiments to study the horizontal structure of the backscatterers as well as to measure the radial velocities for each beam direction. Here we present a method to retrieve gravity wave parameters from these horizontally resolved radial wind variations by applying velocity azimuth display and volume velocity processing. Based on the observations a detailed comparison of the two wind analysis techniques is carried out in order to determine the zonal and meridional wind as well as to measure first order inhomogeneities. Further, we demonstrate the possibility to resolve the horizontal wave properties, e.g. horizontal wavelength, phase velocity and propagation direction. The robustness of the estimated gravity wave parameters is tested by a simple atmospheric model.

  3. Condensation Analysis of Steam/Air Mixtures in Horizontal Tubes

    Perhaps the most common flow configuration in which a convective condensation occurs is a flow in a horizontal circular tube. This configuration is encountered in air-conditioning and refrigeration condensers as well as condensers in Rankine power cycles. Although a convective condensation is also sometimes contrived to occur in a co-current vertical downward flow, a horizontal flow is often preferred because the flow can be repeatedly passed through the heat exchanger core in a serpentine fashion without trapping liquid or vapor in the return bends. Many researchers have investigated a in-tube condensation for horizontal heat exchangers. However, almost all of them obtained tube section-averaged data without a noncondensable gas. Recently, Wu and Vierow have experimentally studied the condensation of steam in a horizontal heat exchanger with air present. In order to measure the condenser tube inner surface temperatures and to calculate the local heat fluxes, they developed an innovative thermocouple design that allowed for nonintrusive measurements. Here we developed a theoretical model using the heat and mass analogy to analyze a steam condensation with a noncondensable gas in horizontal tubes.

  4. Effects of vertical shear in modelling horizontal oceanic dispersion

    The effect of vertical shear on the horizontal dispersion properties of passive tracer particles on the continental shelf of the South Mediterranean is investigated by means of observation and model data. In situ current measurements reveal that vertical gradients of horizontal velocities in the upper mixing layer decorrelate quite fast ( ˜ 1 day), whereas an eddy-permitting ocean model, such as the Mediterranean Forecasting System, tends to overestimate such decorrelation time because of finite resolution effects. Horizontal dispersion, simulated by the Mediterranean sea Forecasting System, is mostly affected by: (1) unresolved scale motions, and mesoscale motions that are largely smoothed out at scales close to the grid spacing; (2) poorly resolved time variability in the profiles of the horizontal velocities in the upper layer. For the case study we have analysed, we show that a suitable use of deterministic kinematic parametrizations is helpful to implement realistic statistical features of tracer dispersion in two and three dimensions. The approach here suggested provides a functional tool to control the horizontal spreading of small organisms or substance concentrations, and is thus relevant for marine biology, pollutant dispersion as well as oil spill applications.

    Ground-source heat pumps are gaining popularity in Eastern Europe, especially those which are using the horizontal ground heat exchanger (GHX). Due to the difficulty of accessing GHX after the installation, materials and the quality of the installation must satisfy the very high requirements. An inaccurate calculation of GHX can be the reason of a scarcity of heat power in a crucial moment. So far, there isn't any appropriate mathematical description of the horizontal GHX which takes into account the mutual influence of GHX pipes on each other. To solve this problem we used the temperature wave approach. As a result, a mathematical model which describes the dependence of the heat transfer rate per unit length of the horizontal GHX pipe on the thermal properties of soil, operating time of GHX and the distance between pipes was obtained. Using this model, heat transfer rates per unit length of a horizontal GHX were plotted as functions of the distance between pipes and operating time. The modeling shows that heat transfer rates decreases rapidly with the distance between pipes lower then 2 meters. After the launch of heat pump, heat power of GHX is reduced during the first 20 - 30 days and get steady after that. The obtained results correlate with experimental data. Therefore the proposed mathematical model can be used to design a horizontal GHX with the optimal characteristics, and predict its capability during operation.

    Horizontal wells are not routinely cored, but are usually drilled in developed fields where good coverage exist. It was recommended that prior to horizontal drilling (which provides a good opportunity to re-evaluate pre-existing cores) an assessment of reservoir descriptions, wellbore stability, and formation damage potential be made. Reservoir description was said to be difficult to establish in horizontal wells that were not cored or logged. Currently used methods include thin-section petrology and mercury injection on drill cuttings from the horizontal well. While horizontal wells are not routinely logged, gamma ray devices that are often run in conjunction with MWD tools were considered capable of providing, continuous log-profile data for more accurate permeability modelling. It was shown that wellbore information could be performed by static or dynamic methods for prediction of the rock failure envelope and safe operating conditions during drilling and production. Mud solids invasion was found to be a key cause of damage that could be assessed and optimized using mercury injection on core or cuttings with a size analysis of mud particles. Coring and core analysis was expected to become a more important source of analytical information when integrated with other sources such as downhole logs.

    Recent research has revealed that horizontal gene transfer and biofilm formation are connected processes. Although published research investigating this interconnectedness is still limited, we will review this subject in order to highlight the potential of these observations because of their believed importance in the understanding of the adaptation and subsequent evolution of social traits in bacteria. Here, we discuss current evidence for such interconnectedness centred on plasmids. Horizontal transfer rates are typically higher in biofilm communities compared with those in planktonic states. Biofilms, furthermore, promote plasmid stability and may enhance the host range of mobile genetic elements that are transferred horizontally. Plasmids, on the other hand, are very well suited to promote the evolution of social traits such as biofilm formation. This, essentially, transpires because plasmids are independent replicons that enhance their own success by promoting inter-bacterial interactions. They typically also carry genes that heighten their hosts' direct fitness. Furthermore, current research shows that the so-called mafia traits encoded on mobile genetic elements can enforce bacteria to maintain stable social interactions. It also indicates that horizontal gene transfer ultimately enhances the relatedness of bacteria carrying the mobile genetic elements of the same origin. The perspective of this review extends to an overall interconnectedness between horizontal gene transfer, mobile genetic elements and social evolution of bacteria.

  8. Sand control completion options for horizontal wells in soft formations

    1999-02-01

    Sand control is required in most soft formations. So far, stand-alone screens have been the primary method. From completion, productivity and longevity perspectives, a high percentage of horizontal oil wells have not achieved the desired result: a sand-free, high sustained-productivity producer. Gas wells seem to have fared better. Disappointments have prompted some companies to reassess procedures and strategies involved with horizontal wells in these reservoirs. Gravel packing offers another option for completing horizontal wells, with the advantage of enhancing productivity. Gravel packing provides a means of filling and stabilizing the wellbore with high-permeability gravel, thereby avoiding the plugging and erosion noted with stand-alone screens. Recently, several operators have performed horizontal gravel packs after experiencing unacceptable performance with stand-alone screens. While each completion option has advantages and disadvantages, all have applications. Some are best suited to particular reservoirs, and as a consequence, the applicability of each completion technique must be assessed in light of particular reservoir conditions and reserves. This discussion will review various applications of soft rock completion technology in horizontal service, along with benefits and shortfalls.

    Monofilament MgB2/Nb/Monel wires were fabricated using three different MgB4 precursors by an internal Mg diffusion (IMD) process. The wire geometry and heat-treatment conditions were optimized in order to improve the critical current density (J c) of the MgB2 wire. The influences of the quality of MgB4 powders, such as the particle size and MgO impurity, on the microstructure and superconducting properties of the wires were discussed. Although there were small amounts of voids, unreacted MgB4 particles and MgO impurity existed in the superconducting layers, and the transport layer J c of the wire with the MgB4 precursor reached 3.0 × 104 A cm-2 at 4.2 K and 10 T, which was comparable to that of IMD-processed wires fabricated using boron precursors. Both the non-barrier J c and engineering J c of MgB2 wire made using a MgB4 precursor were enhanced due to the improved grain connectivity and the enlarged fill factor.

    2007-01-01

    A hybrid model of a subminiature helicopter in horizontal turn is presented. This model is based on a mechanism model and its compensated neural network (NN). First, the nonlinear dynamics of a subminiature helicopter is established. Through the linearization of the nonlinear dynamics on a trim point, the linear time-invariant mechanism model in horizontal turn is obtained. Then a diagonal recursive neural network is used to compensate the model error between the mechanism model and the nonlinear model, thus the hybrid model of a subminiature helicopter in horizontal turn is achieved. Simulation results show that the hybrid model has higher accuracy than the mechanism model and the obtained compensated-NN has good generalization capability.

    A vector bundle F over the tangent bundle TM of a manifold M is said to be a Finsler vector bundle if it is isomorphic to the pull-back π*E of a vector bundle E over M([1]). In this article the authors study the h-Laplace operator in Finsler vector bundles.An h-Laplace operator is defined, first for functions and then for horizontal Finsler forms on E. Using the h-Laplace operator, the authors define the h-harmonic function and h-harmonic horizontal Finsler vector fields, and furthermore prove some integral formulas for the h-Laplace operator, horizontal Finsler vector fields, and scalar fields on E.

    We have performed the first detailed simulation of the horizontal branch of the Sculptor dwarf spheroidal galaxy by means of synthetic modelling techniques,taking consistently into account the star formation history and metallicity evolution as determined from the main sequence and red giant branch spectroscopic observations. The only free parameter in the whole analysis is the integrated mass loss of red giant branch stars. This is the first time that synthetic horizontal branch models, consistent with the complex star formation history of a galaxy, are calculated and matched to the observations. We find that the metallicity range covered by the star formation history, as constrained by observations, plus a simple mass loss law, enable us to cover both the full magnitude and colour range of HB stars. In addition the number count distribution along the observed horizontal branch, can be also reproduced, provided that the red giant branch mass loss is mildly metallicity dependent, with a very small dispersion ...

    1998-12-31

    A number of unconventional sand control completion techniques have been adopted by Petrobras to achieve higher productivity, delay gas/water conning, and to support unconsolidated formations in water injection wells in recently discovered new fields in the Amazon forest and in the deep water offshore Campos Basin. Experiences acquired running screens on 23 horizontal open wells are described. Horizontal wells confirmed the expectations in both locations, i;e. in the Amazon forests water conning was delayed, and in the Marlim field productivity increase to three times that of conventional wells. It was also observed that the API threads used in the screen basepipe for horizontal wells with long radius and short open hole section were adequate, but in the new deep water fields where extended reach wells and long open hole section are likely to be common, it is necessary to use premium threads. 2 refs., 1 tab., 5 figs.

  14. Numerical Modelling of the Mining Induced Horizontal Displacement

    Tajduś, Krzysztof

    2015-12-01

    The paper presents results of numerical calculations and modeling of mining-induced surface deformation based on Finite Element Method (FEM). Applying the numerical method discussed to calculations allows us to assume a larger number of factors, such as rock mass structure, fracture network, rock properties, etc., which essentially affect the results obtained. On the basis of an elastic transversely isotropic model, an analysis of horizontal displacement distribution and surface subsidence was carried out for two sample regions of mines. The results of numerical calculations were later compared with the measured values. Such an analysis proved that the applied numerical model properly described distribution and values of subsidence and slope of subsidence trough, though there were serious differences in the values of calculated horizontal displacement, especially in areas of far influence range. In order to improve the matching, the influence of boundary conditions of the model on the value of calculated horizontal displacement was analyzed. The results are presented in graphs.

    Horizontal launch has been investigated for 60 years by over 130 different studies. During this time only one concept, Pegasus, has ever been in operation. The attractiveness of horizontal launch is the capability to provide a "mobile launch pad" that can use existing aircraft runways, cruise above weather, loiter for mission instructions, and provide precise placement for orbital intercept, rendezvous, or reconnaissance. A jointly sponsored study by DARPA and NASA, completed in 2011, explored the trade space of horizontal launch system concepts which included an exhaustive literature review of the past 70 years. The Horizontal Launch Study identified potential near- and mid-term concepts capable of delivering 15,000 lb payloads to a 28.5 due East inclination, 100 nautical-mile low-Earth orbit. Results are presented for a range of near-term system concepts selected for their availability and relatively low design, development, test, and evaluation (DDT&E) costs. This study identified a viable low-cost development path forward to make a robust and resilient horizontal launch capability a reality.

    The pile-soil system is regarded as a visco-elastic half-space embedded pile. Based on the method of continuum mechanics, a nonlinear mathematical model of pilesoil interaction was established-a coupling nonlinear boundary value problem. Under the case of horizontal vibration, the nonlinearly dynamical characteristics of pile applying the axis force were studied in horizontal direction in frequency domain. The effects of parameters, especially the axis force on the stiffness were studied in detail. The numerical results suggest that it is possible that the pile applying an axis force will lose its stability. So, the effect of the axis force on the pile is considered.

    Three passes of plate rolling during vertical-horizontal rolling process are simulated with explicit dynamic finite element method and updating geometric method. The equivalent strain and stress fields, and shape change at the head and tail of slab during rolling are obtained. The calculated result of the shape at the head and tail of slab is in good agreement with the measured one. The explicit dynamic finite element method and updating geometric method can be used effectively to analyze the multipass vertical-horizontal (V-H) rolling process.

    The contact melting processes of ice, caused by pressure under the two-dimension axisymmetric horizontal columns, are generally studied. The unified mathematical expressions of the characteristic parameters for the pressure contact melting processes are obtained. Applying these expressions to the analysis of the pressure contact melting of ice around the horizontal cylinder, elliptical cylinder and flat plate, the related results in the published literatures are obtained, which prove the correctness and validity of the expressions. In addition, the expressions for the pressure contact melting of ice around the wedge-shaped object are also derived.

    2006-01-01

    Based on a dual-polarization high-frequency wave radar system, an adaptive system using horizontal antennas for the suppression of the Es layer interference (ELI) is described. The data received from the horizontal antennas were correlated with the data received from the Vertically Polarized Antennas (VPAs) to estimate and cancel the interference adaptively in the VPAs. Suppressing the interference after each coherent integration time interval, about 25 dB signal-to-interference ratio is expected with the experimentally derived data.

    We study the evaporation of planets orbiting close to hot (extreme) horizontal branch (EHB) stars. These planets survived the common envelope phase inside the envelope of the reg giant star progenitor. We find that Jupiter-like planets orbiting within 10Ro from an EHB star suffers a non-negligible mass-loss during their 10^8 yr evolution on the horizontal branch. The evaporated gas is ionized and becomes a source of Balmer lines. Such planets might be detected by the periodic variation of the...

    This article looks at a less discussed topic in European legal scholarship: the horizontal direct effect of EU international agreements and the Court of Justice’s apparent reluctance to expressly confirm it. It is argued that the direct effect of EU international agreements has been confirmed...... in proceedings involving private individuals/professionals against the private regulatory bodies of a profession or a State owned and controlled entity. However, direct effect has not yet been expressly confirmed in cases involving veritable horizontal relationships, between private parties of equal positions...

    Full Text Available As mudanças nas distintas frações da matéria orgânica do solo (MOS sob cultivo do eucalipto são pouco conhecidas. Assim, o presente trabalho teve como objetivo avaliar o impacto do cultivo do eucalipto nos estoques de C das diversas frações da MOS, em solos ocupados anteriormente por pastagens degradadas, bem como verificar qual fração da MOS constitui-se um indicador mais sensível à mudança de uso do solo. O estudo foi realizado em plantações comerciais de eucalipto em dois locais na região do Vale do Rio Doce-MG (Belo Oriente e Virginópolis, onde foram determinados em amostras dos solos: C orgânico total (COT, C da fração leve (leve livre - FLL e leve oclusa - FLO, da fração pesada (areia - AR, silte + argila - S + A e argila - ARG, da biomassa microbiana (BM e das frações húmicas (ácidos fúlvicos - FAF, ácidos húmicos - FAH e huminas - FH. Os resultados indicaram que, de maneira geral, os solos sob os diferentes tipos de uso em Virginópolis, em virtude da menor temperatura média anual e maior teor de argila, apresentaram maiores estoques de C em todas as frações da MOS em relação a Belo Oriente. Assim, o seqüestro de C no solo pelo cultivo do eucalipto foi maior em Virginópolis (14,2 t ha-1 que em Belo Oriente (10,0 t ha-1, resultando numa taxa de seqüestro de C de aproximadamente 0,42 e 0,29 t ha-1 ano-1 , respectivamente. Em Belo Oriente, o cultivo do eucalipto favoreceu o aumento no estoque de C das frações ARG, S + A e FH no solo. Comportamento semelhante foi observado para o C das FLL, FAF e FAH, em Virginópolis. Dentre todas as frações da MOS analisadas, a BM e a FLO foram indicadores menos sensíveis às alterações na MOS após três décadas da mudança de uso do solo. Com isso, o COT e a fração leve livre, ácidos fúlvicos, ácidos húmicos e humina foram mais eficientes nesse sentido.Little is known about the changes in different soil organic matter (SOM fractions under short

    Core level X-ray photoelectron spectroscopy (XPS) studies have been carried out on polycrystalline MgB 2 pellets over the whole binding energy range with a view to having an idea of the charge state of magnesium (Mg). We observe three distinct peaks in Mg 2p spectra at 49.3 eV (trace), 51.3 eV (major) and 54.0 eV (trace), corresponding to metallic Mg, MgB 2 and MgCO 3 or, divalent Mg species, respectively. Similar trend has been noticed in Mg 2s spectra. The binding energy of Mg in MgB 2 is lower than that corresponding to Mg(2+), indicative of the fact that the charge state of Mg in MgB 2 is less than (2+). Lowering of the formal charge of Mg promotes the σ → π electron transfer in boron (B) giving rise to holes on the top of the σ-band which are involved in coupling with B E 2g phonons for superconductivity. Through this charge transfer, Mg plays a positive role in hole superconductivity. B 1s spectra consist of three peaks corresponding to MgB 2, boron and B 2O 3. There is also evidence of MgO due to surface oxidation as seen from O 1s spectra.

    Full Text Available Pulping is one important step in wet coffee processing method. Pulping process usually uses a machine which constructed by wood or metal materials. A horizontal single cylinder type of fresh coffee cherries pulping machine is the most popular machine in coffee processing. One of the weaknesses of a horizontal single cylinder type of fresh coffee cherries pulping machine is higher in broken beans. Broken bean is one of mayor aspects in defect system that contribute to low quality. Indonesian Coffee and Cocoa Research Institute has designed and tested a horizontal double cylinder type of fresh coffee cherries pulping machine which resulted in 12.6—21.4% of broken beans. To reduce percentage of broken beans, Indonesian Coffee and Cocoa Research Institute has developed and tested a horizontal triple cylinder type of fresh coffee cherries pulping machine. Material tested was fresh mature Robusta coffee cherries, 60—65% (wet basis moisture content; has classified on 3 levels i.e. unsorted, small and medium, and clean from metal and foreign materials. The result showed that the machine produced 6,340 kg/h in optimal capacity for operational conditions, 1400 rpm rotor rotation speed for unsorted coffee cherries with composition 55.5% whole parchment coffee, 3.66% broken beans, and 1% beans in wet skin.Key words : coffee, pulp, pulper, cylinder, quality.

    The curved segments of roadways are more hazardous because of the additional centripetalforces exerted on a vehicle, driver expectations, and other factors. The safety of a curve is dependent on various factors, most notably by geometric factors, but the location of a curve in relation to other curves is also thought to influence the safety of those curves because of a driver's expectation to encounter additional curves. The link between an individual curve's geometric characteristics and its safety performance has been established, but spatial considerations are typically not included in a safety analysis. The spatial considerations included in this research consisted of four components: distance to adjacent curves, direction of turn of the adjacent curves, and radius and length of the adjacent curves. The primary objective of this paper is to quantify the spatial relationship between adjacent horizontal curves and horizontal curve safety using a crash modification factor. Doing so enables a safety professional to more accurately estimate safety to allocate funding to reduce or prevent future collisions and more efficiently design new roadway sections to minimize crash risk where there will be a series of curves along a route. The most important finding from this research is the statistical significance of spatial considerations for the prediction of horizontal curve safety. The distances to adjacent curves were found to be a reliable predictor of observed collisions. This research recommends a model which utilizes spatial considerations for horizontal curve safety prediction in addition to current Highway Safety Manual prediction capabilities using individual curve geometric features.

Although published research investigating this interconnectedness is still limited, we will review this subject in order to highlight the potential of these observations because...... of their believed importance in the understanding of the adaptation and subsequent evolution of social traits in bacteria. Here, we discuss current evidence for such interconnectedness centred on plasmids.
