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

2. Performance and Egg Quality of Commercial Laying Hens Fed Diets Formulated Using Non-Linear Programming
ABSTRACT Feed formulation using linear programming consists of determining the mixture of feedstuffs required to meet pre-established animal nutritional requirements at the lowest cost. On the other hand, with the use of non-linear programming, it is possible to define nutritional requirements at the time of formulation, aiming at maximum profit. The objecti

3. Optimum mine production rate based on price uncertainty
Abstract The production rate of a mining operation has an important effect on the operational cycle and gross profit, which are often evaluated based on engineering practices. Assessment of the economic performance of mine operations in mining engineering is of great importance because an incorrect production rate can result in significant financial losses.

7. Performance, Carcass Traits and Economic Availability of Muscovy Ducks Fed on Different Nutritional Plans in Different Housing Densities
ABSTRACT The present study aimed to evaluate ducks on performance, carcass traits and economic availability, fed on different phases of nutritional plans and in different housing densities. Two hundred and forty Muscovy ducks of creole lineage were used, distributed in boxes with water and food ad libitum. The experimental design was completely randomized in

8. Densidad y manejo de ejes en plantas injertadas de tomate indeterminadas en invernadero
ABSTRACT Grafting in tomato is a regular production practice aimed to control vascular diseases. Even though grafted plants are more expensive, when a vigorous rootstock is used the plants can be trained using multiple leading shoots, reducing the number of plants per hectare. Seeking to reduce direct labor cost and the cost of the plants, this experiment te

9. MULTICOMMODITY NETWORK FLOWS WITH NONCONVEX ARC COSTS
ABSTRACT We present a survey on nonconvex models and algorithms for multicommodity network design problems. We put in perspective the alternative modelling of these problems, traditionally represented by mixed-integer linear programs, by separable nonconvex arc cost functions. We show in particular that some problems take profit of a continuous modelling and

10. APPLICABILITY OF NON-FEED REMOVAL PROGRAMS TO INDUCE MOLTING INSTEAD OF THE CONVENTIONAL FEED WITHDRAWAL METHOD IN BROWN LAYING HENS
ABSTRACT This study was conducted to compare the applicability of non-feed removal (NFR) programs to induce molting in brown laying hens by feedusing alfalfa meal and barley grain on molting of instead of feed withdrawal in terms of performance, egg quality and profitability. A total of 240, 75-week-old Hy-Line brown laying hens were randomly divided into th

12. Economic and social structures of water buffalo farming in Muş province of Turkey
ABSTRACT The purpose of this study was to analyse the socio-economic structure of water buffalo farming in the province of Muş, in Turkey. The stratified sampling method was used to calculate sample size of buffalo farms in the Central, Korkut, and Hasköy districts of Muş province, where buffalo farming is widespread. Data were collected from the 94 farms
