Drinking water as a risk factor to poultry health

In the poultry industry, the use of water with adequate physical, chemical and microbiological quality it is of fundamental importance. Since many birds have access to the same water source, quality problems will affect a great number of animals. The drinking water plays an important role in the transmission of some bacterial, viral and protozoan diseases that are among the most common poultry diseases. Important factors to prevent waterborne diseases in broiler production are the protection of supply sources, water disinfection and the quality control of microbiological, chemical and physical characteristics. Water is an essential nutrient for birds and therefore quality preservation is fundamental for good herd performance. The farmer may prevent many diseases in bird flocks by controlling the quality of the ingested water, will certainly result in decreased costs and increased profit, two essential aims of animal production nowadays.

Avalia����o do processo industrial da cer��mica vermelha na regi��o do Serid�� - RN

Particularly in Braziland in Rio Grande do Norte, companies manufacturing red ceramic, play an important role as agents of development to study the region Serid��- RN, specific place for carrying out the research. It is observed in this region a concentration of red ceramic industries of small size, which, despite its importance in the ceramic, they are unable to enjoy or use the new forms of administrative management and technological advances designed and offered by universities, centers of research and projects of governments, remained almost entirely outside the progress and modernization, technological and administrative. These companies still have outdated technology, and management processes, providing quality problems and standardization of end products. Upon these conditions are the companies going through crisis and struggling to survive alone and without assistance. The region of Serid��-RN, lets make a detailed case study of red ceramic companies in the region proposed from the existing theoretical and actual lifting of the condition of the product manufacturing red ceramic, allowing through this overview of the implementation of collect samples of raw materials, allowing the study of each ceramic industry that contributed to the participation of the research, which was determined parameters such as: analysis of the physical, chemical and technological properties of raw materials, characterization of the processes used, raising the technological resources considering equipment, machinery, supplies, raw materials and facilities available and its organization by type of products from companies involved in this study. The methodology consists of the following steps: collection of raw material, crushing and screening, characterization of raw materials (liquid limit, chemical analysis, mineralogical analysis, differential thermal analysis, sieve analysis), mixing, forming, cutting, drying and burning of ceramic bodies and bodies of evidence. The results showed that it was clay with distinct characteristics with respect to plasticity. With respect to the different compositions of mixtures of ceramic masses, we conclude that the ceramic properties showed a direct proportionality with increasing fraction of the clay not plastic. However, the compositions of the masses studied proved to be the most appropriate for the types of simulated clay for use in ceramics. Adopted in the ceramic processing made it possible to obtain products the resulted in consistent properties, and in some cases even exceeding the requirements of technical studies and standard-Brazilian clays to obtain ceramic products such as tiles, bricks and tiles to floor. Based on the discussions from the results obtained in the various processing steps of this work, one can draw conclusions according to the physico-chemical and mineralogical properties of raw materials, the properties of ceramic products burned and analysis. This work may be used by other researchers, private companies and governmental organizations, undergraduate students and graduate, can develop studies and future research to: develop projects to modify the furnaces; mapping projects develop and rationalize the exploitation of raw materials ;promoting reforestation and forest management; develop reduction projects and recovery of waste; develop training projects in manpower sector, and develop security projects, improving the conditions of work in the area pottery

Avalia����o da produ����o de sedimento na bacia hidrogr��fica do rio Potengi atrav��s do modelo SWAT

Anthropic disturbances in watersheds, such as inappropriate building development, disorderly land occupation and unplanned land use, may strengthen the sediment yield and the inflow into the estuary, leading to siltation, changes in the reach channel conformation, and ecosystem/water quality problems. Faced with such context, this study aims to assess the applicability of SWAT model to estimate, even in a preliminary way, the sediment yield distribution along the Potengi River watershed, as well as its contribution to the estuary. Furthermore, an assessment of its erosion susceptibility was used for comparison. The susceptibility map was developed by overlaying rainfall erosivity, soil erodibility, the slope of the terrain and land cover. In order to overlap these maps, a multi-criteria analysis through AHP method was applied. The SWAT was run using a five year period (1997-2001), considering three different scenarios based on different sorts of human interference: a) agriculture; b) pasture; and c) no interference (background). Results were analyzed in terms of surface runoff, sediment yield and their propagation along each river section, so that it was possible to find that the regions in the extreme west of the watershed and in the downstream portions returned higher values of sediment yield, reaching respectively 2.8 e 5.1 ton/ha.year, whereas central areas, which were less susceptible, returned the lowest values, never more than 0.7 ton/ha.ano. It was also noticed that in the west sub-watersheds, where one can observe the headwaters, sediment yield was naturally forced by high declivity and weak soils. In another hand, results suggest that the eastern part would not contribute to the sediment inflow into the estuary in a significant way, and the larger part of the sediment yield in that place is due to anthropic activities. For the central region, the analysis of sediment propagation indicates deposition predominance in opposition to transport. Thus, it s not expected that isolated rain storms occurring in the upstream river portions would significantly provide the estuary with sediment. Because the model calibration process hasn t been done yet, it becomes essential to emphasize that values presented here as results should not be applied for pratical aims. Even so, this work warns about the risks of a growth in the alteration of natural land cover, mainly in areas closer to the headwaters and in the downstream Potengi River

Fontes de distor����es da rede geod��sica Brasileira

The Brazilian Geodetic Network started to be established in the early 40's, employing classical surveying methods, such as triangulation and trilateration. With the introduction of satellite positioning systems, such as TRANSIT and GPS, that network was densified. That data was adjusted by employing a variety of methods, yielding distortions in the network that need to be understood. In this work, we analyze and interpret study cases in an attempt to understand the distortions in the Brazilian network. For each case, we performed the network adjustment employing the GHOST software suite. The results show that the distortion is least sensitive to the removal of invar baselines in the classical network. The network would be more affected by the inexistence of Laplace stations and Doppler control points, with differences up to 4.5 m.

Commissioning of the CMS High-Level Trigger with cosmic rays

The CMS High-Level Trigger (HLT) is responsible for ensuring that data samples with potentially interesting events are recorded with high efficiency and good quality. This paper gives an overview of the HLT and focuses on its commissioning using cosmic rays. The selection of triggers that were deployed is presented and the online grouping of triggered events into streams and primary datasets is discussed. Tools for online and offline data quality monitoring for the HLT are described, and the operational performance of the muon HLT algorithms is reviewed. The average time taken for the HLT selection and its dependence on detector and operating conditions are presented. The HLT performed reliably and helped provide a large dataset. This dataset has proven to be invaluable for understanding the performance of the trigger and the CMS experiment as a whole. �� 2010 IOP Publishing Ltd and SISSA.

Avalia����o dos dados decendiais de precipita����o e temperatura m��xima e m��nima do ar simulados pelo modelo ECMWF para o estado de S��o Paulo

The weather and climate has a direct influence in agriculture, it affects all stages of farming, since soil preparation to harvest. Meteorological data derived from automatic or conventional weather stations are used to monitor these effects. These meteorological data has problems like difficulty of data access and low density of meteorological stations in Brazil. Meteorological data from atmospheric models, such as ECMWF (European Center for Medium-Range Weather Forecast) can be an alternative. Thus, the aim of this study was to compare 10-day period precipitation, maximum and minimum air temperature data from the ECMWF model with interpolated maps from 33 weather stations in Sao Paulo state between 2005 and 2010 and generate statistical maps pixel by pixel. Statistical index showed spatially satisfactory (most of the results with R 2 > 0.60, d > 0.7, RMSE < 5��C and < 50 mm; Es < 5��C and < 24 mm) in period and ECMWF model can be recommended for use in the Sao Paulo state.

Qualidade de dados fluviom��tricos obtidos atrav��s de perfilamento ac��stico

Acoustic Doppler current profilers are currently the main option for flow measurement and hydrodynamic monitoring of streams, replacing traditional methods. The spread of such equipment is mainly due to their operational advantages ranging from speed measurement to the greatest detail and amount of information generated about the hydrodynamics of hydrometric sections. As in the use of traditional methods and equipments, the use of acoustic Doppler profilers should be guided by the pursuit of data quality, since these are the basis for project and management of water resources constructions and systems. In this sense, the paper presents an analysis of measurement uncertainties of a hydrometric campaign held in Sapuca�� River (Piranguinho-MG), using two different Doppler profilers - a Rio Grande ADCP 1200 kHz and a Qmetrix Qliner. 10 measurements were performed with each equipment consecutively, following the literature quality protocols, and later, a Type A uncertainty analysis (statistical analysis of several independent observations of the input under the same conditions). The measurements of the ADCP and Qliner presented, respectively, standard uncertainties of 0.679% and 0.508% compared with the averages. These results are satisfactory and acceptable when compared to references in the literature, indicating that the use of Doppler profilers is valid for expansion and upgrade of streamflow measurement networks and generation of hydrological data.

O filtro de Kalman �� aplicado para filtragem inversa ou problema de deconvolu����o. Nesta disserta����o aplicamos o m��todo de Kalman, considerado como uma outra vis��o de processamento no dom��nio do tempo, para separar sinal-ru��do em perfil s��nico admitido como uma realiza����o de um processo estoc��stico n��o estacion��rio. Em um trabalho futuro estudaremos o problema da deconvolu����o. A dedu����o do filtro de Kalman destaca a rela����o entre o filtro de Kalman e o de Wiener. Estas dedu����es s��o baseadas na representa����o do sistema por vari��veis de estado e modelos de processos aleat��rios, com a entrada do sistema linear acrescentado com ru��do branco. Os resultados ilustrados indicam a aplicabilidade dessa t��cnica para uma variedade de problemas de processamento de dados geof��sicos, por exemplo, ideal para well log. O filtro de Kalman oferece aos geof��sicos de explora����o informa����es adicionais para o processamento, problemas de modelamento e a sua solu����o.

Formula����o e implementa����o de um pacote para interpretar mapas magn��ticos utilizando os polin��mios de Walsh

O presente trabalho consiste na formula����o de uma metodologia para interpreta����o autom��tica de dados de campo magn��tico. Desta forma, a sua utiliza����o tornar�� poss��vel a determina����o das fronteiras e magnetiza����o de cada corpo. Na base desta metodologia foram utilizadas as caracter��sticas de varia����es abruptas de magnetiza����o dos corpos. Estas varia����es laterais abruptas ser��o representadas por polin��mios descont��nuos conhecidos como polin��mios de Walsh. Neste trabalho, muitos conceitos novos foram desenvolvidos na aplica����o dos polin��mios de Walsh para resolver problemas de invers��o de dados aeromagn��ticos. Dentre os novos aspectos considerados, podemos citar. (i) - O desenvolvimento de um algoritmo ��timo para gerar um j��go dos polin��mios "quase-ortogonais" baseados na distribui����o de magnetiza����o de Walsh. (ii) - O uso da metodologia damped least squares para estabilizar a solu����o inversa. (iii) - Uma investiga����o dos problemas da n��o-invari��ncia, inerentes quando se usa os polin��mios de Walsh. (iv) - Uma investiga����o da escolha da ordem dos polin��mios, tomando-se em conta as limita����es de resolu����o e o comportamento dos autovalores. Utilizando estas caracter��sticas dos corpos magnetizados �� poss��vel formular o problema direto, ou seja, a magnetiza����o dos corpos obedece a distribui����o de Walsh. �� tamb��m poss��vel formular o problema inverso, na qual a magnetiza����o geradora do campo observado obedece a s��rie de Walsh. Antes da utiliza����o do m��todo �� necess��ria uma primeira estimativa da localiza����o das fontes magn��ticas. Foi escolhida uma metodologia desenvolvida por LOURES (1991), que tem como base a equa����o homog��nea de Euler e cujas exig��ncias necess��rias �� sua utiliza����o �� o conhecimento do campo magn��tico e suas derivadas. Para testar a metodologia com dados reais foi escolhida uma regi��o localizada na bacia sedimentar do Alto Amazonas. Os dados foram obtidos a partir do levantamento aeromagn��tico realizado pela PETROBR��S.
