1. Geomorphology-based unit hydrograph models for flood risk management: case study in Brazilian watersheds with contrasting physiographic characteristics
ABSTRACT Heavy rainfall in conjunction with an increase in population and intensification of agricultural activities have resulted in countless problems related to flooding in watersheds. Among the techniques available for direct surface runoff (DSR) modeling and flood risk management are the Unit Hydrograph (UH) and Instantaneous Unit Hydrograph (IUH). This

2. CLINICAL ASPECTS OF THE POISONING BY THE PESTICIDE ENDOSULFAN
Endosulfan is an organochlorine insecticide, widely used in insect control. Unfortunately, it is also an acute neurotoxic compound to both insects and mammals, including humans, and has been responsible for many severe poisonings and several fatal cases. Endosulfan also imitates or enhances the effect of the female hormone estrogen, having the capability of

3. Plant growth promoting capability and genetic diversity of bacteria isolated from mud volcano and lime cave of Andaman and Nicobar Islands
Twenty four bacterial strains from four different regions of mud volcano and lime cave were isolated to estimate their diversity, plant growth promoting and biocontrol activities to use them as inoculant strains in the fields. An excellent antagonistic effect against four plant pathogens and plant growth promoting properties such as IAA production, HCN produ

4. Spectral indices for the detection of salinity effects in melon plants
Water scarcity and soil salinization affect large semiarid agricultural areas throughout the world. The maintenance of agricultural productivity implies better agricultural practices and a careful selection of resistant crops. A proper monitoring of the physiological status of plants can lead to better knowledge of plant nutritional requirements. Visible and

5. Effect of hydraulic head in the uniformity of irrigation and fertigation under drip system / Efeito da carga hidrÃulica na uniformidade da irrigaÃÃo e fertirrigaÃÃo em sistema de gotejamento
The irrigation tracked by gravity is a technique applied by the family farming that has been spread in Brazil and is used in social programs of some States or directly traded to producers. Irrigation systems have simplified management and let it cheaper. They intensify agricultural yield, increase the prospects of life in the countryside and, therefore, sett

6. Influencia del cambio climático en los escenarios del futuro sobre plantaciones de Eucalipto
The genus Eucalyptus presents a large commercial potential and it is the arboreal species most planted in Brazil. Perspectives of climate change in the future projections of the IPCC (Intergovernmental Panel on Climate Change) indicate that productivity losses may occur in diverse agricultural and forestry crops. The objective of this study was to determine

7. Screening of actinomycetes from earthworm castings for their antimicrobial activity and industrial enzymes
Actinomycetes from earthworm castings were isolated and screened for their antimicrobial activity and industrial enzymes. A total of 48 isolates were obtained from 12 samples of earthworm castings. Highest numbers of isolates were recovered from forest site (58.33 %) as compared to grassland (25%) and agricultural land (16.66%). The growth patterns, mycelial

8. Radarsat backscattering from an agricultural scene.
Orbital remote sensing in the microwave electromagnetic region has been presented as an important tool for agriculture monitoring. The satellite systems in operation have almost all-weather capability and high spatial resolution, which are features appropriated for agriculture. However, for full exploration of these data, an understanding of the relationship

9. Desenvolvimento de descritores de imagens para reconhecimento de padrões de plantas invasoras (folhas largas e folhas estreitas)
In Brazil, the development of tools for weeds recognition, capable of aiding risk detection and decision making on the fieldwork is still embryonic. This masters thesis presents the development of a pattern recognition system that recognizes weeds and gives the occupation percentage of wide and narrow leaves in an agricultural production system, with digital

11. The pluriactivity as the family farmer social reproduction strategy at Pirituba II Farm rural settlement / A pluriatividade como estrategia de reprodução social do agricultor familiar no projeto de assentamento rural Fazenda Pirituba II
The pluriactivity consists in non-agricultural and agricultural activities that are developed by the family farmers and its members. This study sought to understand pluriactivity as a social process arising from the continuously constructed relationships by different social actors, among which the family farmer. Among the problems faced by family farmers, es
