Qualidade Higiênico-Sanitária e Demanda de Cloro da Água de Dessedentação de Galinhas de Postura Coletadas em Bebedouros Tipo Nipple e Taça

O objetivo deste estudo foi avaliar a influência de dois tipos de bebedouros nipple e taça, utilizados na dessedentação de aves de postura e o incremento da demanda de cloro na água oferecida pelos dois tipos de bebedouros estudados. Foram realizadas as contagens de coliformes totais, coliformes fecais, Escherichia coli, estreptococos fecais e microrganismos mesófilos. Os resultados obtidos figuraram que as amostras de água dos reservatórios, de ambos os bebedouros, apresentaram-se contaminadas microbiologicamente antes de passarem pelos bebedouros. A contaminação por bactérias de poluição fecal foi maior nas amostras colhidas nos bebedouros tipo taça, assim como eles foram responsáveis por um maior acúmulo de matéria orgânica, tendo então uma elevada demanda de cloro e uma maior influência na depreciação da qualidade da água fornecida às aves. Dos dois tipos de bebedouros estudados, o tipo nipple mostrou ser o menos deletério no que concerne à qualidade da água entretanto, independente do tipo de bebedouro utilizado na dessedentação das aves, a desinfecção da água é um ato imprescindível à manutenção de sua qualidade e à eliminação de futuros patógenos.

Survey for Tick-Borne Zoonoses in the State of Espirito Santo, Southeastern Brazil

Blood samples collected from 201 humans, 92 dogs, and 27 horses in the state of Espirito Santo, Brazil, were tested by polymerase chain reaction, indirect immunofluorescence assays, and indirect enzyme-linked immunosorbent assay for tick-borne diseases (rickettsiosis, ehrlichiosis, anaplasmosis, borreliosis, babesiosis). Our results indicated that the surveyed counties are endemic for spotted fever group rickettsiosis because sera from 70 (34.8%) humans, 7 (7.6%) dogs, and 7 (25.9%) horses were reactive to at least one of the six Rickettsia species tested. Although there was evidence of ehrlichiosis (Ehrlichia canis) and babesiosis (Babesia cams vogeli, Theileria equi) in domestic animals, no human was positive for babesiosis and only four individuals were serologically positive for E. canis. Borrelia burgdorferi-serologic reactive sera were rare among humans and horses, but encompassed 51% of the canine samples, suggesting that dogs and their ticks can be part of the epidemiological cycle of the causative agent of the Brazilian zoonosis, named Baggio-Yoshinari Syndrome.

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

Demanda energética na subsolagem realizada antes e depois de diferentes sistemas de preparo periódico do solo

A subsolagem é uma das operações mecanizadas de elevado custo e demanda energética por área, tradicionalmente utilizada pelos agricultores antes do preparo do solo na descompactação de camadas adensadas. Este trabalho teve como objetivo avaliar a demanda energética na operação de subsolagem realizada antes e depois de diferentes sistemas de preparo periódico num solo classificado como Nitossolo Vermelho Distroférrico. Os sistemas de preparo periódico foram: aração com discos; aração com discos mais uma gradagem de nivelamento; grade aradora; grade aradora mais gradagem de nivelamento e escarificação. O trator utilizado como fonte de potência no experimento foi um Valmet 128 (4x2tda). A demanda energética por área foi menor na subsolagem realizada depois do preparo periódico do solo, proporcionando uma economia de 21,9%. A realização da subsolagem depois do preparo periódico do solo resultou numa diminuição da exigência de força de tração em 21,1% e da potência disponível na barra de tração em 15%.

Demanda energética nas operações mecanizadas na silagem de milho no sistema de silo bag

Foi avaliado o consumo energético das operações mecanizadas envolvidas na produção de silagem de planta inteira e silagem de grão úmido de milho, tendo como referência o processamento seco desse cereal. O ensaio foi conduzido na Fazenda Experimental Lageado, pertencente à Faculdade de Ciências Agronômicas, e nas instalações da Faculdade de Medicina Veterinária e Zootecnia - UNESP, localizada no município de Botucatu - SP. O delineamento experimental foi em blocos ao acaso, com parcelas subdivididas no tempo (três épocas de colheita: silagem de planta inteira, silagem de grão úmido e colheita de grãos secos), com 10 repetições. As análises estatísticas foram realizadas por meio do programa ESTAT, pelo teste de média de Tukey, a 5% de probabilidade. A silagem de planta inteira teve o maior consumo de combustível por área. A secagem dos grãos de 15,5% para 13% foi responsável por 87% do gasto de energia por área. A silagem de grão úmido demandou o menor uso de energia por área nas operações mecanizadas.

Estudo da demanda energética e desagregação do solo em diferentes sequências operacionais de preparo periódico

The correct selection of the operational sequence of soil tillage is essential to reduce the cost of agricultural mechanization in the regions that mobilize intensively the soil. The objective of this work was to evaluate the energetic demand and disaggregation of the soil in different operational sequences of subsoiling and systems of periodic soil tillage. The experimental design was blocks at random, in a factorial model 5 x 2 with 5 replications, being 5 tillage systems (D - Disc plow, Dn - disc plow followed at leveler rail, G - weight rail, Gn - weight rail followed of leveler rail and E - Stirrer.) and two sequencies of subsoiling (SP - Subsoiling - tillage and PS - Tillage - subsoiling). There were evaluated the energetic demand, fuel consumption by area and the soil disaggregation. The results showed that the operational sequence tillage of the soil subsoiling (PS) had a lower energetic requirement, except for the stirrer, the sequence tillage the soil - subsoiling consumed less fuel and soil disaggregation didn't show statistic variation.

Demanda energética em diferentes sistemas de preparo periódico do solo antes e depois da subsolagem

Both the inadequate use and the ignorance of the different soil tillage implements available in the home market has become one of the leading motives of failures, related to soil and water conservation. The periodical tillage is traditionally utilized after subsoiling for soil clod breaking, leveling and residue incorporation. This work aimed to evaluate the energy requirement for different periodical soil tillage systems performed before and after subsoiling in a soil classified as Distroferric Red Nitosol. The periodic tillage systems were: disk plowing; disk plowing plus one leveling harrowing; disk harrow; disk harrow plus leveling harrowing stirring. The experimental design was a 5x2 factorial scheme with 5 completely randomized blocks. The results show that the periodic soil preparation systems based on disks have better energy efficiency when performed before the operation of subsoiling. The system of soil preparation with harrowing obtained the lower energy demand, in relation to other periodic soil preparation systems, when done after subsoiling.

Estimação da demanda de instalações elétricas de edificações com múltiplas unidades de consumo

This work aims to predict the total maximum demand of a transformer that will be used in power systems to attend a Multiple Unit Consumption (MUC) in design. In 1987, COSERN noted that calculation of maximum total demand for a building should be different from that which defines the scaling of the input protection extension in order to not overestimate the power of the transformer. Since then there have been many changes, both in consumption habits of the population, as in electrical appliances, so that this work will endeavor to improve the estimation of peak demand. For the survey, data were collected for identification and electrical projects in different MUCs located in Natal. In some of them, measurements were made of demand for 7 consecutive days and adjusted for an integration interval of 30 minutes. The estimation of the maximum demand was made through mathematical models that calculate the desired response from a set of information previously known of MUCs. The models tested were simple linear regressions, multiple linear regressions and artificial neural networks. The various calculated results over the study were compared, and ultimately, the best answer found was put into comparison with the previously proposed model

Extração e Representação de Conhecimento de Séries Temporais de Demanda de Energia Elétrica Usando TSKR

The opening of the Brazilian market of electricity and competitiveness between companies in the energy sector make the search for useful information and tools that will assist in decision making activities, increase by the concessionaires. An important source of knowledge for these utilities is the time series of energy demand. The identification of behavior patterns and description of events become important for the planning execution, seeking improvements in service quality and financial benefits. This dissertation presents a methodology based on mining and representation tools of time series, in order to extract knowledge that relate series of electricity demand in various substations connected of a electric utility. The method exploits the relationship of duration, coincidence and partial order of events in multi-dimensionals time series. To represent the knowledge is used the language proposed by Mörchen (2005) called Time Series Knowledge Representation (TSKR). We conducted a case study using time series of energy demand of 8 substations interconnected by a ring system, which feeds the metropolitan area of Goiânia-GO, provided by CELG (Companhia Energética de Goiás), responsible for the service of power distribution in the state of Goiás (Brazil). Using the proposed methodology were extracted three levels of knowledge that describe the behavior of the system studied, representing clearly the system dynamics, becoming a tool to assist planning activities

Ocorrência de Gonipterus scutellatus Gyllenhal (Coleoptera: Curculionidae) em plantações de eucalipto no Estado do Espírirto Santo

O gorgulho do eucalipto Gonipterus scutellatus Gyllenhal foi encontrado no Estado do Espírito Santo atacando plantações clonais de Eucalyptus urophylla x E. grandis (híbrido “urograndis”). Essa espécie de gorgulho é conhecida no Brasil desde 1979, tendo sua distribuição geográfica restrita aos estados da região Sul e São Paulo. A introdução do inseto no Estado do Espírito Santo foi provavelmente acidental e sua ocorrência tem se limitado à região central do Estado. Nos levantamentos de campo não foi detectado o parasitóide de ovos Anaphes nitens (Hymenoptera: Mymaridae), que é o principal inimigo natural do gorgulho do eucalipto.

Produção de tapetes de grama Santo Agostinho submetida a doses de nitrogênio

Nitrogen is the nutrient that provides the greatest turfgrass growth responses and the adequate nitrogen fertilization can provide sod formation in less time and firm to be handled after harvest. This study aimed to evaluate the effect of nitrogen levels in the formation of St. Augustinegrass sod. The experiment was conducted in a sod production farm in Itapetininga, SP. The experimental design was a randomized blocks with four replications. The treatments consisted of five N doses: 0, 150, 300, 450 and 600 kg ha(-1), split into three applications. Increased levels of nitrogen affected the soil cover rate by the St. Augustinegrass reducing the time for sod formation. The leaf N concentration and intensity of green grass were influenced by nitrogen doses, and with the rate of green coverage rate (GCR) of soil, can be used to assist in the recommendation of N doses. Rate of 430 kg ha(-1) of N provided the production of St. Augustinegrass sod resistant the harvest and transport, within ten months.

Relação entre hábitos bucais, alterações oronasofaringianas e mal-oclusões em pré-escolares de Vitória, Espírito Santo, Brasil

O objetivo deste estudo foi estimar a prevalência das mal-oclusões e variáveis a elas associadas, como hábitos deletérios (HD) e as alterações oronasofaringianas (AO), respiração bucal, deglutição atípica e fonação atípica, em crianças com idade de três anos, no Município de Vitória, Espírito Santo, Brasil. A amostra constituiu-se de 291 crianças de ambos os sexos, matriculadas nos Centros de Educação Infantil, selecionadas por meio de amostragem probabilística por conglomerados. A análise de regressão logística indicou maior risco relativo (RR) de crianças com sobressaliência alterada, mordida aberta e mordida cruzada, em apresentar: respiração bucal (RR = 1,89; IC: 1,56-2,03), (RR = 2,46; IC: 2,00-3,02), (RR = 1,45; IC: 1,23-1,72); deglutição atípica (RR = 2,57; IC: 1,87-3,52), (RR = 3,49; IC: 2,53-4,81), (RR = 1,86; IC: 1,46-2,39) e fonação atípica (RR = 2,25; IC: 1,66-3,05), (RR = 3,18; IC: 2,38-4,25), (RR = 1,71; IC: 1,32-2,22), respectivamente. Foi mostrado haver associação entre sucção de dedo e de chupeta com sobressaliência alterada (p < 0,001) e sucção de chupeta e mordida aberta (p < 0,001). Esses resultados indicam que a prevalência das mal-oclusões está associada aos HD e às AO.

Avaliação da disponibilidade hídrica e da demanda hídrica no trecho do Rio Piranhas-Açu entre os açudes Coremas-mãe D´água e Armando Ribeiro Gonçalves

Piranhas-Açu basin is a Federal watershed with a drainage area of 43.681,5 km2, sited at Brazilian northeast semi arid, with 60% of your area in Paraiba State and 40% in Rio Grande do Norte State. The main river, Piranhas-Açu, has strategic importance for development of these states, because it s an essential source for many socio-economics activities developed along watercourse. The river s reach between Coremas-Mãe D`água Dam and Armando Ribeiro Gonçalves Dam has many irrigation projects, and supply many riverside cities. All this activities practiced in this river s reach consumes high water volumes. Due the importance of this stream and the necessity of an adequate management, this work aims for an impartial and detailed evaluation of real water supply conditions in this river s reach, by the application of hydrological modeling, including the arrangement of main dams in tributaries, and storage reservoir water balance. The rainfall-discharge model s applied in each sub-basins it was selected the model MODHISA- Hydrological Model of Semi Arid, that is a concentrated model with easy application. The simulation produced 50 years of inflows into the reservoirs, for which, were constructed the guaranties curves; and produced 50 years of synthetic discharge data in relevant points on the river and on its affluents; so it was constructed the permanence curves. Confronting the available discharge with the current and futures volumes of raw water captured in this river s reach, it was verified that de demands have high guaranties. This work concluded that the MODHISA Model is suitable to reproduce the hydrologic characteristics of Piranhas-Açu sub-basins, and showing good results

Santo de casa faz milagre: Luíz da Câmara Cascudo, o padroeiro literário da cidade de Natal

Assuming that the subject is a draft work in permanent invention, the biographical texts, memories written by Luís da Câmara Cascudo, between 1967 and 1969 were read as part of a discursive strategy created by the potiguar memorialist regarding the construction of a self-image profoundly connected to the space of his house, which decisively collaborated so that the province teacher and researcher after announcing his official retirement in 1968 was revered in the city where he had been born, grown up and lived throughout his whole life and considered as the prophet of his own country (or rather, as the literary patron of Natal). Our work begins with some reading about the manner as the potiguar memorialist selected, ordered and spatialized his childhood memories. In the following chapter, we problematized the meanings assigned by Câmara Cascudo to his house in Tirol - where the young prince Cascudinho (little Cascudo) used to live - transformed into the neighborhood principality. It finishes with memories from the retired old man with the purpose of making us think about the sacredness process master Cascudo s house has gone through. The space where he had lived for almost forty years of his life and produced a great part of his works, was elected as a monument in his memory, as his own incarnation, as guarantee of his eternity and perenniality, as a sanctuary and place of worship and have been kept by the actions that, still nowadays, institutionalize it as his sacred space
