As a result of advancing globalization and economic activities that go beyond national borders, gross domestic product (GDP) and gross national product (GNP) are becoming dissociated. The two are the same to the extent that they measure (gross) added value generated during a specific period (e.g., one year). A difference between them is, generally speaking, the former focuses on whether economi...

Liquid scintillation counting (LSC) is an adequate nuclear technique to determine radioactivity levels, as verified by this study for the determination of the gross alpha and beta activities of aqueous samples because of its simplicity and low associated cost comparison with other techniques. This paper discusses a new approach to the monitoring of gross alpha and gross beta activities in water...

mining and metallurgical projects are among those that require the most sizeable invest-ments undertaken in iran. one target of the current development plan and the ministry of mines and industries has been to attract foreign investment in mining projects. a survey of world-class mining companies was conducted to determine their expectations and in order to recommend a frame work for iran aimed...

Sierra Leone is blessed with abundant natural resources but yet prone to environmental degradation due to the mining operations. Most often, the mining communities are faced with social tensions, as a result of the possible trade-off between the expected employment impact and the cost of mining operations to the environment. Over the past decades, the contribution of the mining sector to the de...

the main purpose of this study was to determine which correlate, perceived motor competence or motor skill competence, best predicts girls' physical activity behavior.a sample of 352 girls (mean age=8.7, sd=0.3 yr) participated in this study. to assess motor skill competence and perceived motor competence, each child completed the test of gross motor development-2 and physical ability sub-scale...

today, with emphasis on the mechanical heart and heart transplantation from one human to another andone species to another, a knowledge of the anatomy of the bird’s heart could contribute to theseaccomplishments. eight male adult ostriches were used to study the heart macroscopically. this studyrevealed that the ostrich heart has some different features from the other birds. in the ostrich, fib...

and study its approximation in the sense of Bhatnagar-Gross-Krook (a BGKlike approximation for short). In particular, we aim to describe the conservation law (1.1) as the hydrodynamic limit of the stochastic BGK model, as the microscopic scale ε goes to 0. The literature devoted to the deterministic counterpart, i.e. corresponding to the situation Φ = 0, is quite extensive (see [1], [11], [15],...
