1. Optical sorting technology for waste management from the Boukhadra iron ore mine (NE Algeria)
Abstract Mining processes in the iron ore mine of Boukhadra, Tebessa (NE Algeria) generated thousands of tons of mining wastes every year, which represents a real threat to the environment, leading to hazardous effects for the resident population of the region. The aim of this study is the selective sorting of the Boukhadra mining wastes for valorization. Th

2. Difference in nutritional values between wild and farmed tambaqui in the north region of Brazil
Abstract The demand for wild tambaqui has led to overfishing of their natural stocks, and has thus increased the demand for farmed fish. This has raised a question regarding the nutritional value of these groups of individuals; to see if they differ when they grow in wild and farmed environments. The meat of 28 tambaqui was evaluated by measuring the moistur

7. Carbon and nutrient stocks of three Fabaceae trees used for forest restoration and subjected to fertilization in Amazonia
ABSTRACT Amazonia is crucial to global carbon cycle. Deforestation continues to be one of the main causes of the release of C into the atmosphere, but forest restoration plantations can reverse this scenario. However, there is still diffuse information about the C and nutrient stocks in the vegetation biomass. We investigated the carbon and nutrient stocks o

8. A new rapid colourimetric method for testing Mycobacterium tuberculosis susceptibility to isoniazid and rifampicin: a crystal violet decolourisation assay
The aim of this study was to investigate the performance of a new and accurate method for the detection of isoniazid (INH) and rifampicin (RIF) resistance among Mycobacterium tuberculosis isolates using a crystal violet decolourisation assay (CVDA). Fifty-five M. tuberculosis isolates obtained from culture stocks stored at -80ºC were tested. After bacterial

9. Quantifying soil carbon stocks and greenhouse gas fluxes in the sugarcane agrosystem: point of view
Strategies to mitigate climate change through the use of biofuels (such as ethanol) are associated not only to the increase in the amount of C stored in soils but also to the reduction of GHG emissions to the atmosphere.This report mainly aimed to propose appropriate methodologies for the determinations of soil organic carbon stocks and greenhouse gas fluxes

10. Desenvolvimento de um sistema de recirculação com uso de wetlands construídas para efluentes da piscicultura / Development of a recirculating system using constructed wetlands for aquaculture effluents
Global aquaculture has been growing very fast in recent decades due to several factors, including: population growth, demand for low calorie protein and especially the reduction of natural fish stocks. Brazil has enormous potential to become a world leader in fisheries production in captivity. However, the development of aquaculture in Brazil must be conduct

12. Comparação entre métricas de risco para otimizar carteiras de investimentos em ações / Comparison of risk metrics to optimize portfolios of stock investments
O trabalho de Markowitz (1952) modificou a forma de analisar o problema de formação de portfólios de ações. Pesquisadores clássicos como Sharpe (1964) e Lintner (1965) ampliaram as discussões, além de provocarem o levantamento de dúvidas e questionamentos a respeito do assunto. Quanto aos parâmetros para otimização dos portfólios, além do model
