1. Determinación del consumo de agua potable durante la construcción de viviendas en una zona semi desértica de Chile
ABSTRACT In recent years, water scarcity in northern Chile has increased markedly, leading to an over exploitation of groundwater aquifers. In the construction sector, water is used in large quantities throughout the different activities of the construction projects, this fact makes essential to quantify the water consumption in order to know the real demand

3. Performance and radial distribution profiles of a variable flow rate sprinkler developed for precision irrigation
Variable rate sprinklers (VRS) have been developed to promote localized water application of irrigated areas. In Precision Irrigation, VRS permits better control of flow adjustment and, at the same time, provides satisfactory radial distribution profiles for various pressures and flow rates are really necessary. The objective of this work was to evaluate the

4. Tamanhos de recipientes e o uso de hidrogel no estabelecimento de mudas de espécies florestais nativas / Sizes of containers and the use of hydrogel in the establishment of native forest species seedlings
The demand for ecological restorations project, using total planting techniques, has increased in recent years, with the consequent optimizations need of inputs for such activity that, besides increasing the seedlings survival in the field, is essential for the sector. Thus, environmental compensation, generated by the work of the southern section of the Rod

5. Modelo para determinação da perda de carga contínua em tubos elásticos / Model for determining the continuous head losses in elastic pipe
Total head losses are accounted in the irrigation hydraulic projects, that would be the continuous losses and the local head losses, aiming to maximize the uniformity of water distribution, characterizing an adequate pump set to the irrigation system e thus, minimizing the project implantation and annual costs. With informatics support, complex calculation p

10. IMPACTO DE AGROTÓXICOS USADOS NA LAVOURA DE ARROZ IRRIGADO EM ORGANISMOS BENTÔNICOS / THE IMPACT OF PESTICIDES ON BENTHIC ORGANISMS IN FLOODED RICEFIELDS
The objective of this project was to investigate the impact of different pesticides used in the ricefield on the density and diversity of benthic organisms. In the experiment, two collects of soil were made to identify and quantify benthic organisms, one in the 28th and other in the 84th days after the entry of water in the ricefield. We used a cylindrical c

11. Expressão de três isoformas de galactinol sintase em plantas de Coffea arabica L. submetidas a estresses abióticos
Raffinose family oligosaccharides (RFOs) play multiple roles in plants, mainly in response to environmental stresses such as drought, salinity and extreme temperatures. Galactinol synthase (GolS) is the enzyme that catalyzes the first step of the biosynthesis of oligosaccharides of RFOs and plays an important regulatory role in the partition of carbon betwee

12. Interceptação de água pelo dossel e influência da época da irrigação na qualidade da cana de açúcar / Water interception by the canopy and influence irrigation on the quality of sugarcane
Sugarcane (Saccharum officinarum) is a crop of great economic importance in Brazil. Its main products are sugar and ethanol (hydrated and anhydrous). Indispensable to the world market, other products that are also originated from this crop and should be emphasized are the spirit (cachaça); the bagasse, which is used mainly as an energy source; vinasse, whic
