Professor Ahiakpor’s (2008) comment on my article (Garrison, 2004) warrants a comprehensive response. Ahiakpor questions the validity of my use of the production possibilities frontier, the plausibility of the market mechanisms illuminated by my analytical framework, and my interpretation of Ludwig von Mises’s notions of “forced saving” in connection with business cycles. According to the Austr...

A total of 60 male mule ducks and 60 male Muscovy ducks were allotted into three groups (n = 20) to estimate the effects of overfeeding (two and four meals) versus ad libitum feeding on productive performance traits, foie gras production, internal organs, and blood parameters. The results show that force-feeding four meals significantly increased (P < 0.01) body weight, weight gain, and gain pe...

The purpose of the study was to investigate the effects of one night's sleep deprivation on the cardiorespiratory responses to exercise during the follicular and luteal phases of the menstrual cycle. We have studied nine, healthy females aged 24-35 years with regular menstrual cycles. Each subject performed spirometric tests at rest and then an incremental exercise testing during 11-13 days of ...

To evaluate the effects of working with modern insulation materials (rock and glass wool), the members of the Copenhagen Union of Insulation Workers were invited to participate in a study based on a health examination that included lung function tests. Three hundred and forty men (74%) agreed to participate, and 166 bus drivers served as the control group. Age distribution, height, and smoking ...

We hypothesised that exposure to workplace aerosols may lead to lung function impairment among cement production workers.Our study included 4966 workers in 24 cement production plants. Based on 6111 thoracic aerosol samples and information from questionnaires we estimated arithmetic mean exposure levels by plant and job type. Dynamic lung volumes were assessed by repeated spirometry testing dur...

The production of a narrow, heavy, occasionally convective snowband that fell within a modest surface cyclone on 19 January 1995 is examined using gridded model output from a successful numerical simulation performed using the University of Wisconsin—Nonhydrostatic Modeling System. It is found that the snowband was produced by a thermally direct vertical circulation forced by significant lower-...

The basic industries exhibit an increasing need for efficient management of all factors reducing the operation costs, leading to the necessity of a global multi-objective optimization methodology enabling the generation of optimum strategies fulfilling the required restrictions. In this paper a genetic algorithm is developed and applied for the optimal assignment of all the production sections ...
