Serological Evidence of Bovine Herpesvirus 5 (BoHV-5) in Cattle at the Colombia's Eastern Plains

Several diseases involve the nervous system of cattle, among which infections with Rabies Virus and Bovine Herpes Virus 5 (BoHV-5) are noteworthy. In order to detect seropositive animals to BoHV-5, 156 Brahman-Zebu bovines blood samples from Colombia's eastern plains were analyzed through seroneutralization assay; the area has a history of animals dying with nervous symptoms and which rule out the disease of rabies. All animals were over one year old and randomly selected from two different herds reporting no vaccination for infectious bovine rhinotracheitis in a period exceeding one year. Results indicated seropositivity for BoHV-5 in 91 cases (58.4%), of which 88 were also seropositive for bovine herpes virus 1 (BoHV-1), while 41 were seronegative for both agents. 22/64 seronegative cases for BoHV-5 were seropositive for BoHV-1 and 2/43 seronegative cases for BoHV-1 were seropositive for BoHV-5, and consequently, these animals could be only infected by encephalitis herpes virus. With these initial findings, emphasis its placed on the need establish the true impact of the disease in Colombia and proposes the epidemiological surveillance of cattle in the region studied in order to establish mechanisms for control of viral infection.

Atenção à saúde da pessoa idosa na estratégia saúde da família no município de Santo Antônio/RN: um estudo de caso

According to demographic estimates, by the year 2025 Brazil will be the sixth country in the world in number of elderly. For this reason, it is a purpose of public policies to help people to reach that age being healthier. The current health care model of health surveillance through the Family Health Strategy (EFS, in portuguese) is configured as a gateway into the care of the elderly in the Unified Health System (SUS, in portuguese). It is also an area of development of practices to promote health, prevention and control of chronic nondegenerative diseases. The aim of this study was to analyze the health care of the elderly provided by ESF professionals for the achievement of a full care. The study is descriptive case study with a quantitative approach, performed in the city of Santo Antônio/RN. The population included all health professionals, who are FHS members of the city that agreed to participate of the survey, a total of 80 professionals. Data were collected using a structured questionnaire, having mostly closed questions and divided into two parts: one containing sociodemographic information of health professionals and vocational training and the other, the activities carried on by the professionals in senior care, being analyzed from a database tabulated in a spreadsheet and discussed according to the descriptive statistics in tables, graphs and charts using frequencies, medians and values of central tendency. It was verified a predominance of professionals who finished highschool, mostly female, aged from 30 to 34 years old, with training completed in the last 10 years, without being graduated in the field of geriatrics or gerontology and mostly without training in gerontology. Family members and caregivers were the components of the social support network most identified by the professionals (66.3%).The elderly access to the Family Health Basic Unit was considered by83.8% of professionals as the most important factor that interferes in the activities of health care of the elderly. Considering the inclusion of the family in care: 98.8% of professionals consider the family as one of the goals of care, but 82.5% assist the family to know their role and participate in the care of the elderly, emphasizing that no professional makes use of tools for evaluating the functionality of the family. Regarding the actions taken to assist the elderly, 91.25% have home visits program to the elderly, 88.75% use the host program; 77.5% know the habits of life, cultural, ethical and religious values of the elderly, their families and their community ;51.25% complement the activities through intersectoral actions, 50%participate in groups of living with the elderly; 33.75% keeps track and maintain updated the health information of the elderly; 11.25% of the professionals perform the Single Therapy Planning (PTS, in portuguese) and few implement the actions to promote health according to PTS; there is a deficit in the number of professional categories in the identification and monitoring of the frail older people in their households. It is concluded that the health care of the elderly developed by ESF professionals differs among the professional categories. It was identified weaknesses in the promotion of an active and healthy aging and also in the establishment of an integrated and full care of the elderly. It is recommended the adoption of permanent educational activities by the City Management, initially for ESF professionals in the the perspective of the guidelines of the National Policy of Health Care for the Elderly and later to the other professionals that are part of the health care network of the elderly, at all levels of care in the city for the development of strategies and practices that promote the improvement of the quality of healthcare for the elderly, expecting concrete and effective results in terms of promoting health within Brazilian reality

Análise de desempenho de vendas em telecomunicações utilizando técnicas de mineração de dados

Nowadays, telecommunications is one of the most dynamic and strategic areas in the world. Organizations are always seeking to find new management practices within an ever increasing competitive environment where resources are getting scarce. In this scenario, data obtained from business and corporate processes have even greater importance, although this data is not yet adequately explored. Knowledge Discovery in Databases (KDD) appears then, as an option to allow the study of complex problems in different areas of management. This work proposes both a systematization of KDD activities using concepts from different methodologies, such as CRISP-DM, SEMMA and FAYYAD approaches and a study concerning the viability of multivariate regression analysis models to explain corporative telecommunications sales using performance indicators. Thus, statistical methods were outlined to analyze the effects of such indicators on the behavior of business productivity. According to business and standard statistical analysis, equations were defined and fit to their respective determination coefficients. Tests of hypotheses were also conducted on parameters with the purpose of validating the regression models. The results show that there is a relationship between these development indicators and the amount of sales

Uma abordagem híbrida para o problema de seleção de fornecedores em cadeia de suprimentos

This work presents a hybrid approach for the supplier selection problem in Supply Chain Management. We joined decision-making philosophy by researchers from business school and researchers from engineering in order to deal with the problem more extensively. We utilized traditional multicriteria decision-making methods, like AHP and TOPSIS, in order to evaluate alternatives according decision maker s preferences. The both techiniques were modeled by using definitions from the Fuzzy Sets Theory to deal with imprecise data. Additionally, we proposed a multiobjetive GRASP algorithm to perform an order allocation procedure between all pre-selected alternatives. These alternatives must to be pre-qualified on the basis of the AHP and TOPSIS methods before entering the LCR. Our allocation procedure has presented low CPU times for five pseudorandom instances, containing up to 1000 alternatives, as well as good values for all considered objectives. This way, we consider the proposed model as appropriate to solve the supplier selection problem in the SCM context. It can be used to help decision makers in reducing lead times, cost and risks in their supply chain. The proposed model can also improve firm s efficiency in relation to business strategies, according decision makers, even when a large number of alternatives must be considered, differently from classical models in purchasing literature

Uma arquitetura baseada em SCTP e SIP para suporte a aplicações VoIP móveis e a especificação formal do seu módulo de controle

New versions of SCTP protocol allow the implementation of handover procedures in the transport layer, as well as the supply of a partially reliable communication service. A communication architecture is proposed herein, integrating SCTP with the session initiation protocol, SIP, besides additional protocols. This architecture is intended to handle voice applications over IP networks with mobility requirements. User localization procedures are specified in the application layer as well, using SIP, as an alternative mean to the mechanisms used by traditional protocols, that support mobility in the network layer. The SDL formal specification language is used to specify the operation of a control module, which coordinates the operation of the system component protocols. This formal specification is intended to prevent ambiguities and inconsistencies in the definition of this module, assisting in the correct implementation of the elements of this architecture

Códigos de sustentação da linguagem no cotidiano prisional do Rio Grande do Norte: penitenciária estadual de Parnamirim

The quarrel, in this study, tells about the language as social practical in the daily of Parnamirim State Prison that is integrated to the Rio Grande do Norte Penitentiary System - SISPERN, destined for men in fulfilment of penalty privative of freedom, in closed regimen. For the accomplishment of the research, the delimited objectives had been to analyze the language repertoires created in the prisional daily, trying to identify how it´s turned into distinct forms of resistance to the mechanisms of control in penitentiary system; to investigate which are the language repertoires created from the new sociability forms developed among prisoners and identify how the language repertoires are expressed in the daily prisional on relations/exercises of power not-institutionalized. In the methodological aspect, the study is in a qualitative boarding, that has as main instrument the interview. The inquiry was possible by means of using instruments for data collection, like as: the direct comment in the prisional daily duly registered as researcher´s ethnographical procedure, the analysis of interns´ cadastre handbooks and the application of half-structuralized interview, to the subjects of the research. The construction and understanding of the study object had been based on authors who argue on the arrest, as: Foucault, Goffman, Carvalho Filho and, in particular was searched the theorical referencial that approaches the language in a social and cultural perspective: Orlandi, Manfred, Bastos and Candiotto, amongst others. Beyond the normative endorsement of the Brazilian legislation, through the Law of Criminal Execution, of the Criminal Code and the Federal Constitution of the country and the legal apparatus in state scope. Still in the research methodological perspective, after the collection the data had been submitted to an analysis of the speech from Foucalt´s theory and in the Orlandi´s perspective, being also qualitative and quantitative. The results had evidenced that the social and juridical profile of the population in the site inquired is not different of others Brazilian prisons, composed for men, in its majority, with age band between 21 and 30 years old, prisoners for practicing crimes against the patrimony, against life, amongst others, and, in special, criminal recidivists. It evidenced, still, that the daily prisional of PSP is characterized for a sociocultural diversity expressed in the relations of power not institutionalized, that contributes for the formation and division of the groups, each one using a set of language codes/ repertoires sustentation. Therefore, the language, in the daily prisional, is one of the ways to understand the singularity of the sociability relations and as social practicing mediated by relations/exercises of power and antagonistic interests, in which each group aims first of all, their own interests. It represents the complexity of the social relations, in the prisional space, with diverse effects, in function of the situation and the moment. The language in the arrest, beyond the communication function, assumes and represents central element for the sociability human being, contributes for its changings and it´s configured as one of the resistance forms of prisoners against the controling, disciplining and monitoring mechanisms of penitentiary system

Crystallization, preliminary X-ray diffraction analysis and Patterson search of oxyhaemoglobin I from the wolf (Chrysocyon brachiurus)

Oxyhaemoglobin I isolated from the Brazilian wolf Chrysocyon brachiurus has been crystallized and X-ray diffraction data has been collected to 2.06 A resolution using a synchrotron-radiation source. Crystals were determined to belong to the space group P2(1)2(1)2(1) and preliminary structural analysis revealed the presence of one tetramer in the asymmetric unit. The structure was determined using standard molecular-replacement techniques and is currently being refined using maximum-likelihood protocols. This is the first haemoglobin isolated from a member of the Canidae family to be crystallized and it will provide further insights in the comparative biochemistry of vertebrate haemoglobins.

Definição de requisitos de software baseada numa arquitetura de modelagem de negócios

Não é uma tarefa fácil definir requisitos para os sistemas de software que darão suporte a um negócio, dada a dinâmica de mudanças nos processos. O levantamento de requisitos tem sido feito de forma empírica, sem o apoio de métodos sistematizados que garantam o desenvolvimento baseado nos reais objetivos do negócio. A engenharia de software carece de métodos que tornem mais ordenadas e metódicas as etapas de modelagem de negócios e de levantamento de requisitos de um sistema. Neste artigo é apresentada uma metodologia de desenvolvimento de software resultante da incorporação de atividades propostas para modelagem de negócios e levantamento de requisitos, baseadas em uma arquitetura de modelagem de negócios. Essas atividades tornam o desenvolvimento de software mais sistemático e alinhado aos objetivos da organização, e podem ser incorporadas em qualquer metodologia de desenvolvimento baseada no UP (Unified Process - Processo Unificado).

THE ESSENTIAL ROLE OF ZINC IN GROWTH

Zinc is known to play a relevant role in growth and development. The basic mechanisms of action of this trace element are intimately linked to the structure and action of countless enzymes involved in many different metabolic processes. In this respect, when zinc specifically acts on cartilage growth it is involved in multiple enzymatic reactions which make this a multifactorial event. Thus, we may divide the actions of zinc into three distinct types: 1) action on taste and smell acuity, appetite regulation, and food consumption and regulation; 2) action on DNA and RNA synthesis stimulating a) cell replication and differentiation of chondrocytes, osteoblasts and fibroblasts; b) cell transcription culminating in the synthesis of somatomedin-C (liver), alkaline phosphatase, collagen and osteocalcin (bone), and c) protein, carbohydrate and lipid metabolism, that is intimately related to the mechanisms of smell, taste, appetite, and food consumption and utilization; 3) action on hormonal mediation by participating in a) GH synthesis and secretion in somatomammotroph cells, b) the action of GH on liver somatomedin-C production, and c) somatomedin-C activation in bone cartilage. In addition to these multiple functions, zinc also interacts with other hormones somehow related to bone growth such as testosterone, thyroid hormones, insulin, and vitamin D-3.On the basis of the above considerations, we conclude that the integration of these mechanisms contributes to the perfect physiological functioning of bone. Tn the presence of zinc deficiency, this homeostasis is impaired, causing the weight-height deficiency detected in several species studied, the human species in particular.

Ticks associated with armadillo (Euphractus sexcinctus) and anteater (Myrmecophaga tridactyla) of Emas National Park, State of Goias, Brazil

This study was conducted in October 1998 and November 1999 in the Emas National Park (131,868 ha), a savanna-type cerrado region situated in the far south of Goias State, Brazil, near the geographic center of South America (15degrees-23degrees S; 45degrees-55degrees W). Animals were captured with the aid of nets and anesthetized (15 mg/kg ketamine + 1 mg/kg xylasine) in order to collect ticks for identification and to establish laboratory colonies. They included giant anteaters (Myrmecophaga tridactyla) (n = 4) and yellow armadillos (Euphractus sexcinctus) (n = 6). Free-living ticks (larvae, nymphs, and adults) were collected from the field by using a 1 X 2-m flannel cloth. Free-living ticks were identified as Amblyomma sp., A. cajennense, and A. triste. Adult ticks collected from anteaters were identified as Amblyomma cajennense and A. nodosum and from armadillos as A. pseudoconcolor and A. nodosum. The relevance of these host-tick relationships to possible mechanisms underlying emergence of tick-borne pathogens of importance to public health is discussed.

Citrus and coffee strains of Xylella fastidiosa induce Pierce's disease in grapevine

Xylella fastidiosa causes citrus variegated chlorosis (CVC) disease in Brazil and Pierce's disease of grapevines in the United States. Both of these diseases cause significant production problems in the respective industries. The recent establishment of the glassy-winged sharpshooter in California has radically increased the threat posed by Pierces disease to California viticulture. Populations of this insect reach very high levels in citrus groves in California and move from the orchards into the vineyards, where they acquire inoculum and spread Pierce's disease in the vineyards. Here we show that strains of X. fastidiosa isolated from diseased citrus and coffee in Brazil can incite symptoms of Pierce's disease after mechanical inoculation into seven commercial Vitis vinifera varieties grown in Brazil and California. Thus, any future introduction of the CVC strains of X. fastidiosa into the United States would pose a threat to both the sweet orange and grapevine industries. Previous work has clearly shown that the strains of X. fastidiosa isolated from Pierce's disease- and CVC-affected plants are the most distantly related of all strains in the diverse taxon X. fastidiosa. The ability of citrus strains of X. fastidiosa to incite disease in grapevine is therefore surprising and creates an experimental system with which to dissect mechanisms used by X.,fastidiosa in plant colonization and disease development using the full genome sequence data that has recently become available for both the citrus and grapevine strains of this pathogen.
