1. Multi-stage dumping sequence - a feasible waste management alternative for open pit mining
Abstract Waste management and environmental aspects are progressively gathering attention in the mining industry. Mine planners must deal with increasingly complex tasks to balance between ore block schedules, waste disposal, operational cost and environmental reclamation. The mine incomes are generally related to mining and processing of the ore, thus most

3. Assessment of coconut fibers for textile applications
ABSTRACT Brazil is the fourth larger producer in coconut fruit in the world. However, the industry processes only a small portion of coconut byproducts, which have caused serious environmental problems. The purpose of this article is to test an alternative for the recovery of coconut byproduct. In a series of experiments, recovered coconut fibers (coir) were

6. Understanding heat stress in beef cattle
ABSTRACT Thermal stress is the result of a misbalance between heat produced or gained from the environment and the amount of heat lost to the environment. The level of thermal stress can range from minor or no effect to death of vulnerable animals. Under summertime conditions, thermal stress results in hyperthermia or heat stress. Heat stress in feedlot catt

7. 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

8. Effects of temperature on the feeding behavior of Alabama argillacea (Hübner) (Lepidoptera: Noctuidae) on Bt and non-Bt cotton plants
ABSTRACT The host acceptance behavior and environmental factors as temperature affect the feeding behavior of Lepidoptera pests. Thus, they must be considered in studies about the risk potential of resistance evolution. The current study sets the differences in the feeding behavior of neonate Alabama argillacea (Hübner) (Lepidoptera: Noctuidae) larvae expos

9. COMPOSTING TIME REDUCTION OF AGRO-INDUSTRIAL WASTES
ABSTRACT The agro-industrialization of animal products has led to a significant waste generation, which has been stabilized by composting process in specialized plants. Waste stabilization time on composting depends on the handling used. 12 treatments were performed, three frequency turnings combined with two environmental conditions (with and without covera

10. Environmental and physiological variables during the catching of broilers
The objective of this study was to determine the critical points of the operation of broiler catching for transport to the processing plant from animal and operational perspectives. During catching, chickens, environmental variables (temperature and relative humidity) were constantly monitored to determine the Enthalpy Comfort Index (IEC). Also, the physiolo

11. Laminated composite based on polyester geotextile fibers and polyurethane resin for coating wood structures
New environmental laws have restricted the use of hardwood trees in overhead power lines structures, such as, poles and cross-arms, leading companies to seek alternative materials. Reforested wood coated with polymeric resin has been proposed as an environmental friendly solution, with improved electrical properties and protection against external agents, e.

12. Mild environmental intervention in mother-infant interactions reduces social play behavior in rats
During early life, animals are sensitive to environmental events that may lead to short-term and long-lasting changes in their neurobiology and behavior, which could be related to increased risk for psychopathology. Neonatal handling is an experimental intervention in the mother-infant relationship. Based on previous studies, it is known to decrease rat pups
