13. Conservation tillage, optimal water and organic nutrient supply enhance soil microbial activities during wheat (Triticum Aestivum L.) cultivation
The field experiments were conducted on sandy loam soil at New Delhi, during 2007 and 2008 to investigate the effect of conservation tillage, irrigation regimes (sub-optimal, optimal and supra-optimal water regimes), and integrated nutrient management (INM) practices on soil biological parameters in wheat cultivation. The conservation tillage soils has shown

14. Hydrodynamic modeling and morphological analysis of Lake Água Preta: one of the water sources of Belém-PA-Brazil
The main contribution from this paper includes the hydrodynamic modeling and morphological analysis of Lake Água Preta in Belém city, Pará State, Brazil. The lake bathymetry was taken through the data provided by COSANPA (the local sanitation and water supply company) dating back to 1975, and from a 2009 field study. Both bathymetries produced two terrain

16. Importance of appropriated sectorization to reduce real water loss in public supply system. / Importância da setorização adequada para combate às perdas reais de água de abastecimento público.
The following study aims to present the effect of pressure reducing in the distribution networks over the water real loss. For development of the studies, were collected field data that allowed to evaluate the distribution systems conditions and build mathematical models for hydraulic simulations. From the hydraulics models, were developed cases for the Wate

17. MODELO HIDRÁULICO BASEADO NO MÉTODO DAS CARACTERÍSTICAS E ALGORITMOS GENÉTICOS PARA OTIMIZAÇÃO DA OPERAÇÃO DE REDES DE ABASTECIMENTO DE ÁGUA E DE ESTAÇÕES DE BOMBEAMENTO
A hydraulic model was developed for simulation of water supply networks using the Method of Characteristics (MOC), introducing new features to the CALHIDREDMT model, proposed by Righetto (1994). The model uses the concept of pseudo-transient, using a fictitious value for the wave celerity. Simulations were performed in networks equipped with reservoirs, tank

18. CARTOGRAFIA REGIONAL DA LEPTOSPIROSE: DINÂMICA ESPAÇO-TEMPORAL DA PATOLOGIA NA 4 COORDENADORIA REGIONAL DE SAÚDE, RS. / REGIONAL MAPPING OF THE LEPTOSPIROSIS: SPATIOTEMPORAL DYNAMICS OF PATHOLOGY AT THE 4TH REGIONAL HEALTH DISTRICT, RS.
Leptospirosis is a ubiquitous disease, waterborne, with several animal reservoirs (wild and domestic) and urban and rural transmission, receiving climatic/socioeconomic influences. Its manifestations vary from asymptomatic and light tables to hemorrhagic fevers. This study aimed to evaluate the cases reported in SINAN of the 4CRS, RS, from 1999 to 2006, perf

19. Saberes da terra: o lúdico em Bombas, uma comunidade quilombola (estudo de caso etnográfico) / Knowledge of the land: playfulness from Bombas, a black quilombola community (an ethnographic case study).
A History and Historiography of Education case study project supported by ethnographic elements and intended to understand, acknowledge, record and think about forms of play in a black community. The research is conducted in the community of Bombas, located in Iporanga, São Paulo, which is currently attempting to be recognized as a remnant quilombo (ancient

20. Distribuição vertical e sazonal da comunidade fitoplanctônica em dois reservatórios eutróficos do Estado de Pernambuco
The dynamics of the phytoplankton community in aquatic ecosystems provides considerable diagnostic information and serves as a sensitive tool for the indication of environmental changes, enabling the prediction of changes in any body of water. The vertical distribution of these organisms in eutrophic reservoirs remains an under-explored field of study, but i

21. RURAL TOURISTIC INVENTARY IN ENVIRONMENT UNITS STUDY CASE: RIVER WATERSHED OF IBICUI RIVER UP TO THE DAM SATURNINO DE BRITO / INVENTÁRIO TURÍSTICO RURAL EM UNIDADES AMBIENTAIS ESTUDO DE CASO: BACIA HIDROGRÁFICA DAS NASCENTES DO RIO IBICUÍ-MIRIM ATÉ A BARRAGEM SATURNINO DE BRITO
Tourism has among its characteristics the dependence on the free time of people who travel, an unstable demand for intangible and diversified products, different public according to the season of year and static environment without the possibility of stocking its production. Besides the public, receptive, food, transportation, recreational and entertainment

This study has as a main objective to make a detailed stratigraphic analysis of the Aptian-Albian interval in the east part of Araripe Basin, NE of Brazil which correspond, litostratigraphically, to Rio Da Batateira, Crato, Ipubi and Romualdo formations. The stratigraphic analysis was based on three different stages, the 1D, 2D and 3D analysis; these ones we

Qualidade e decomposiÃÃo de materiais orgÃnicos presentes em propriedades rurais do semi-Ãrido / Quality and decomposition os organic materials found in farms of the semi-arid region of ne Brazil / Qualidade e decomposiÃÃo de materiais orgÃnicos presentes em propriedades rurais do semi-Ãrido / Quality and decomposition os organic materials found in farms of the semi-arid region of ne Brazil
Owners of small farms in the semi-arid region of NE Brazil usually do not use chemical fertilizers to ameliorate soil fertility. Therefore, the nutrients supply for their crops have to rely on soil organic matter mineralization or, in some cases, on the fertilization with animal manure (mostly from cattle or goats). However, the manure produced in these farm
