1. Effects of long-term controlled internal drug release reuse on reproductive performance, hormone profiles, and economic profit of sheep
ABSTRACT Fifty-seven multiparous Awassi ewes in the breeding season were used to compare the effects of controlled internal drug release (CIDR) reuse on hormone profiles, reproductive performance, and economic production. Ewes were randomly allotted to one of three CIDR treatments: new (control), once-used, and twice-used; treatment lasted 12 days. Blood sam

2. Grade uncertainty embedded in long term scheduling: stochastic mine planning
Abstract The inclusion of grade uncertainty for multivariate mineral deposits is of great importance for the correct management of subsequent decisions involved in mining planning. Mapping grade uncertainties allows maximization of profit and resource extraction. In this article, the co-simulation turning band algorithm is applied with the aim of predicting

5. Economic analysis, performance, and feed efficiency in feedlot lambs
ABSTRACT The objective of this study was to evaluate residual feed intake (RFI), residual intake and body weight gain (RIG) and their relationship with other traits of efficiency, performance, and economic analysis of sheep. Lambs (n = 102) were evaluated during 56 days and a herd consisting of 500 ewes was simulated with the mean of dry matter intake (DMI)

6. 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

7. Productive performance and economic evaluation of tilapia stocked in different times of the year
ABSTRACT This study aimed to determine production cycles based on the stocking period and the influence of the cycles on productive performance indices, production costs, and profitability. The present study was carried out on a fish farm located in Palmital - SP, Brazil, which consists of 2706 m3 of net cages with an annual production of 400 tons of tilapia

8. Impacto de diferentes algoritmos e geometria de depósitos minerais no planejamento de longo prazo
The main objective of mine planning is to determine ore quantity and quality distribution along a time sequence, i.e., scheduling the ore necessary to make the project technically and economic viable. These temporal sequences are fundamental for the financial success of a mine activity and presently this optimal sequence can be obtained through various minin

9. Simulação do impacto da disponibilidade de sistemas no retorno econômico e produção de petróleo / Simulation of the impact of system availability on profit and petroleum production
The reservoir simulation is the basis for the forecasts of production, dimensioning of surface equipments and the planning of activities related to production. Therefore, a production strategy which generates oil and gas production curves over the operational lifetime. However, even without considering geological and economic uncertainties, in practice, this

11. Maximum profit cogeneration plant - MPCP: system modeling, optimization problem formulation, and solution
The well-known CGAM optimization problem was formulated to serve as a benchmark for comparison of different thermoeconomic methodologies. The CGAM cogeneration plant produced 30 MW of power and 14 kg/s of saturated vapor at 20 bar. The objective function was the total cost rate of the system, related to thermodynamic variables and installation costs. Because

12. Avaliação financeira da produção de maracujá.
ABSTRACT: This paper presents a budget analysis of passionflower (Passiflora edulis Sims f. flavicarpa Deg.) production. Four financial methods were used: 1) Payback; 2) Net Present Value (NPV); 3) Internal Rate of Return (IRR); 4) and Benefit / Cost Ratio (BCR). This document intends to be a quick reference for field technicians and farmers and not a deep s
