| The aspects involved in broiler water intake are not well known, despite the importance of water in animal nutrition and physiology. Water intake behavior should be taken into account when deciding on different types of drinkers. Bell and nipple drinkers are the most commonly used in commercial broiler production. Broilers were housed in cages equipped with two different drinker types and raised at two different environmental temperatures (25 and 34 ºC) to evaluate water intake behavior and volume. Broiler water intake behavior was influenced by drinker type. Birds visited bell drinkers less often, but presented higher total water intake per visit to the drinker as compared to those drinking from nipple drinkers. The results of this study suggest that both... |

| This chapter addresses Embrapa?s contribution to target 6.3, which relates to water quality and pollution reduction. Decreasing the availability of good quality water is a growing and global concern. Monitoring water quality, coupled with the adoption of good soil and water management practices and the use of technologies to reduce the production of contaminants, can contribute significantly to minimizing this problem and ensuring good quality water for all. The present chapter sought to list search results that point out paths that can be followed. |

| The relative merits of different systems of property rights to allocate water among different extractive uses are evaluated for the case where variability of supply is important. Three systems of property rights are considered. In the first, variable supply is dealt with through the use of water entitlements defined as shares of the total quantity available. In the second, there are two types of water entitlements, one for water with a high security of supply and the other a lower security right for the residual supply. The third is a system of entitlements specified as state-contingent claims. With zero transaction costs, all systems are efficient. In the realistic situation where transaction costs matter, the system based on state-contingent claims is... |

| Whereas water is an important input in rice production, China faces severe problems with increasing demand for water and limited water resources. In conventional paddy production, one of the most important irrigated crops, a significant amount of irrigation water is lost due to percolation and evaporation. Therefore, it exist a vivid research in water saving rice technologies. This paper analyzes the adoption of one of these water-saving rice production technologies, the so-called Ground Cover Rice Production System (GCRPS), in the Hubei province. Based on farm survey data several factors which affect the adoption decision could be identified. The adoption decision is treated as a binary choice problem and therefore a probit model is used for the... |

| Water returning to a river from an irrigated watershed could increase the water temperature in the river. The objective of this study was to compare the temperature of irrigation return flow water with the temperature of the diverted irrigation water. Water temperature was measured weekly in the main irrigation canal, 24 return flow streams and one ephemeral stream from 2005 to 2008 in the Upper Snake Rock (USR) watershed. The USR is an 82,000 ha watershed in southern Idaho, USA with about 60% of the area surface irrigated and the remaining area sprinkler irrigated. Median annual water temperatures in irrigation return flow streams were not greater than the water diverted from the river, suggesting that water flowing through the canal system and furrow... |

| The aim of this work was to isolate and identify yeasts from sand and sea water collected in two beaches of Olinda, Pernambuco state, Brazil. Thirty two samples of both sand and water in both beaches were obtained in the dry (December 2000 and February 2001) and rainy (June and July 2001) seasons. Two hundred and ninety two strains of yeast were obtained, and they belonged to four genera and 31 species. Candida was the most prevalent genus. Candida catenulata, C. fenica, C. sake, Brettanomyces bruxelenses and Rhodotorula mucilaginosa were the most commonly found species in both beaches Bairro Novo and Casa Caiada. |

| This paper considers the effect of water content on mechanical properties of polyamide 6 when used in a humid environment. First an experimental section presents the tensile behavior of polyamide with different amounts of water, with and without a through-thickness water gradient. Water profiles are introduced by immersion in sea water at 25 °C. The effect of testing temperature is also investigated in order to consider the influence of macromolecular chain mobility on the mechanical behavior. Then, in a second section, modelling of yield stress is proposed based on physical considerations. This can be used for life time prediction of PA6 in humid environment when plasticization is the main degradation mechanism. |

| Исследовано содержание ртути в мягких тканях и раковинах мидий Mytilus galhprovinciulis Lam. в зависимости от индивидуального возраста моллюсков из акваторий мыса Тарханкут, Карадагского природного заповедника, г. Ялты, в т.ч. глубоководного выброса хозяйственно-бытовых и сточных вод. Линейные размеры раковины мидии в зависимости от их возраста хорошо апроксимируются степенной функцией, а концентрация ртути в теле и раковине - квадратичной параболой. Акватория г. Ялты характеризуется высоким уровнем загрязнения мидий ртутью (выше предельно-допустимой концентрации, установленной требованиями санитарных норм для пищевых продуктов), начиная с самых мелких животных. Фоновые значения содержания Hg в воде во всех районах исследований ниже ПДК для природных... |
