The main concern of an olive grower is primarily to achieve more income and profits. A harvesting method having higher efficiency and better fruit and oil quality, but a higher operation cost leads to a lower benefit. A study was carried out to evaluate the techno-economic performances of Trunk Shaker (TS) and Mechanical Harvest Aid (MHA) shaker for harvesting the yellow and Manzanilla olive cu...

There are not, and probably never will be, enough resources to satisfy the community's desires for things that improve the quality of life. This poses the necessity for choice, and hence the consideration of priorities. In the medical field two distinct kinds of choice arise: one at the clinical level and the other in the planning process. At the point of contact with a particular patient, a do...

The techniques and methods of developing cost models for respirators are discussed. Models are developed and implemented in this study for nineteen types of respirators in two major classes (air-purifying and supplied-air) and one LEV system. One respirator model is selected for detailed discussion from among the twenty models. The technical cost method is used in constructing the cost models f...

OBJECTIVE Epidemiologic research suggests that significant public health benefits can accrue from preventive interventions that delay the initiation of youth alcohol use. This analysis compares the cost effectiveness of tvo interventions designed for general population families of adolescents. It also conservatively estimates their benefit-cost ratios and net benefits. METHOD Cost-effectivene...

Order is the key word of science. Scientists have tried to order and explain all the phenomena of the universe. They found that the planets and stars move along predictable paths, discovered the laws of gravitation and devised formulae to describe inheritance. For them, the universe is like a clock. Their mission is to discover and explain the mechanism of this clock and thus explain the laws t...
