1. Natural erosion potential in the Mato Grosso state, Brazil
RESUMO O entendimento da suscetibilidade de solos à erosão é crucial para o planejamento de uso da terra visando uma agricultura sustentável. O estudo teve como objetivo determinar a variabilidade espacial do potencial natural de erosão para o Estado de Mato Grosso, um importante centro agrícola do Brasil. O potencial natural de erosão foi calculado u

2. BIODEGRADABLE SODIUM CARBOXYMETHYL CELLULOSE MEMBRANES CONTAINING MELALEUCA ESSENTIAL OILS FOR WOUND CARE MATERIAL
NaCMC is a biocompatible polymer that can be crosslinked with citric acid to form a gel matrix. Melaleuca oils have antimicrobial and anti-inflammatory properties with potential for wound healing. The goal of this work was to investigate the characteristics of NaCMC-Melaleuca oils gels. The gels were characterized by FTIR, TGA, mechanical analysis, and in vi

3. Morphometry and longitudinal profile of the river cobras sub-basin in planning the location of underground dams
RESUMO Um estudo na sub-bacia hidrográfica do rio das Cobras foi realizado com o objetivo de avaliar as características morfométricas e o perfil longitudinal da bacia hidrográfica, como ferramenta de planejamento na locação de barragens subterrâneas. Os parâmetros morfométricos - coeficiente de compacidade, fator forma, densidade de drenagem e índi

4. Evaluation of yeast culture and direct-fed microbial on gut histology and serum components of broilers challenged with suboptimal diets under heat stress
ABSTRACT. The use of antibiotics in feed for growth promotion has been restricted in many countries, thus it is of interest to investigate potential alternatives for enhancing growth performance in birds. An experiment was carried out to evaluate the concurrent use of prebiotic and probiotic on gut histology and some blood chemicals of broiler chickens dur

5. Estimates of soil losses by the erosion potential method in tropical latosols
RESUMO A erosão hídrica é um dos principais problemas enfrentados na cafeicultura, pois promove a degradação ambiental e a diminuição da produção agrícola. As estimativas da erosão auxiliam no planejamento de práticas e sistemas de manejo conservacionistas e permitem aferir as taxas de perdas do solo. Assim, o objetivo do trabalho foi estimar a p

6. Assessment of the effects of vegetational cover on the long-term stabilityof a waste rock dump
Abstract Waste rock dump reclamation includes re-grading the banks to flatten the overall slope followed by re-vegetation. These measures are required to reduce surface erosion, provide physical stability, and meet future use goals. In some cases, the presence of trees can cause localized shear zones in a waste rock dump by the load of the tree mass and the

7. Floral phenology, seed germination and hybrid plants of the Amerindian yam (Dioscorea trifida)
RESUMO O cará (Dioscorea trifida) é uma planta alimentícia nativa da Amazônia. Diversas variedades locais são cultivadas por agricultores familiares para consumo e comercialização local. Porém, processos socioeconômicos podem estar causando a erosão genética da espécie. O conhecimento sobre a reprodução sexuada da espécie é essencial para sua

8. Gestão dos resíduos sólidos orgânicos urbanos no Brasil: do ordenamento jurídico à realidade
RESUMO No Brasil, ainda se enterram, queimam ou lançam a céu aberto milhões de toneladas de resíduos orgânicos, em decorrência do desconhecimento de seu potencial de aproveitamento e dos impactos negativos que provocam quando dispostos inadequadamente. Este trabalho buscou analisar a inserção e a aplicação dos princípios e objetivos da Política N

9. Forage sorghum-legumes intercropping: effect on growth, yields, nutritional quality and economic returns
ABSTRACT Cereal-legumes intercropping is among the most economical and effective agronomic strategies to boost forage biomass production, nutritional quality and monetary returns. This review synthesizes the research findings on how intercropping affects productivity, quality, competitiveness and economic viability of sorghum-legumes mixed, row and strip int

10. Water Erosion in Oxisols under Coffee Cultivation
ABSTRACT Water erosion is one of the main environmental impacts of land use. When soil and water losses occur, nutrients essential for the growth and maintenance of plants are removed, with harmful outcomes on the sustainability of agriculture and the environment. In addition, they lead to other deleterious effects, such as sedimentation and eutrophication o

11. Crop residue harvest for bioenergy production and its implications on soil functioning and plant growth: A review
ABSTRACT: The use of crop residues as a bioenergy feedstock is considered a potential strategy to mitigate greenhouse gas (GHG) emissions. However, indiscriminate harvesting of crop residues can induce deleterious effects on soil functioning, plant growth and other ecosystem services. Here, we have summarized the information available in the literature to id

12. Spatial Distribution of Annual and Monthly Rainfall Erosivity in the Jaguarí River Basin
ABSTRACT The Jaguarí River Basin forms the main water supply sources for the São Paulo Metropolitan Region and other cities in the state. Since the kinetic energy of rainfall is the driving force of water erosion, the main cause of land and water degradation, we tested the hypothesis of correlation between the erosive potential of rainfall (erosivity) and
