13. Advancing impact evaluation in applied limnology
Resumo Avaliações de impacto acuradas de diferentes intervenções são necessidades na área ambiental. Nesse contexto, o principal desafio é identificar relações causais com o objetivo de compreender como diferentes intervenções afetam os sistemas de interesse. Para tal, a lógica contrafactual pode ser usada para estimar impactos de intervenções

15. Ecotoxicology assay for the evaluation of environmental water quality in a tropical urban estuary
Abstract Most studies evaluating the impacts of river pollution in the semi-arid region of Brazil have been geared towards physiochemical analyses, and investigations of the adverse effects of water pollution on associated organisms are scarce. This study aimed to evaluate the water quality in the Poxim river estuary in Aracaju, Sergipe throughout the dry an

16. The Impact of Traditional Silvopastoral System on the Mixed Ombrophilous Forest Remnants
ABSTRACT The results of an evaluation of the impact of traditional silvopastoral system on floristic and phytosociology of the Mixed Ombrophilous Forest (MOF) remnants, named caívas, in the North Plateau of Santa Catarina, South of Brazil are shown here to contribute to a better understanding of the impact of human activities on natural environments,.

17. Efectos del uso de electrolitos soportes en ensayos electroquímicos de la aleación Al-4%Mg expuesta a bioetanol combustible
ABSTRACT The growth of world energy demand directly affects the consumption of petroleum-based fuels, increasing the negative impact of the use of these fuels and the decrease of crude oil reserves. This creates an opportunity for the use of fuels that are more efficient, of low environmental impact and, above all, of a renewable nature. Bioethanol is a biof

18. Impact of embryo transfer phenotypic records on large-scale beef cattle genetic evaluations
ABSTRACT We aimed to evaluate the impact of using embryo transfer (ET) information on weaning weight estimated breeding values (EBV) and its accuracy. Data from Hereford and Braford cattle, raised under extensive conditions in Southern Brazil, were used. A model that included ET information in addition to maternal (genetic and permanent environmental) effect

19. Evaluation of some oxidative-stress and antioxidant markers in goats during estrous cycle under Egyptian environmental conditions
ABSTRACT The objective of this study was to explore the impact of thermal stress on hormonal level and antioxidant activity in goats during various phases of the estrous cycle in the Egyptian summer. Forty cycling does were allocated to two groups (20 animals each) divided by season (mild/hot). Daily meteorological, rectal temperature, and respiratory rate d

20. Dissolved organic matter (C, N, P) on the Pernambuco coast and Fernando de Noronha archipelago (Tropical Zone of Western South Atlantic, Brazil) - A contribution to the evaluation of environmental impact
Resumo Os compostos orgânicos dissolvidos encontrados na água do mar oferecem uma indicação de processos biogeoquímicos e influência antropogênica à luz de suas concentrações e comportamentos associados a diferentes áreas oceânicas. Os aportes de rios contribuem com cargas orgânicas para a água do mar de acordo com o nível de influência natur

21. Multi-criteria decision analysis and spatial statistic: an approach to determining human vulnerability to vector transmission of Trypanosoma cruzi
BACKGROUND Chagas disease (CD), caused by the protozoan Trypanosoma cruzi, is a neglected human disease. It is endemic to the Americas and is estimated to have an economic impact, including lost productivity and disability, of 7 billion dollars per year on average. OBJECTIVES To assess vulnerability to vector-borne transmission of T. cruzi in domiciliary

22. Structural Analysis of the Double Bottom Structure During Ship Grounding by Finite Element Approach
Abstract Possibility of a water-transportation mode to experience numerous accidental loads is predicted limitless and always demand sustainable analysis. Impact phenomenon raises as main reason of environmental damage, for instance, grounding contributes in form of short-time impact and produces massive damage on the bottom structure of a marine vessels, e.

23. Evaluation of nickel and copper catalysts in biogas reforming for hydrogen production in SOFC
ABSTRACT The solid oxide fuel cells (SOFC) enable the efficient generation of clean energy, fitting the current requirements of the growing demand for electricity and for the environment preservation. When powered with biogas (from digesters of municipal wastes), the SOFCs also contribute to reduce the environmental impact of these wastes. The most suitable

24. Evaluation of the influence of the use of waste from the processing of rice in physicochemical properties and biodegradability of PHB in composites
The high calorific value of rice husks has elevated its reuse as an energy source; however, the burning of these shells generates a waste ash from rice husk ash (RHA), which makes its disposal a concern. Despite advances, biodegradable polymers are not yet able to compete with those of traditional thermoplastics, which have lower production cost and higher p
