Infiltration is one of the most important hydraulic parameters affecting surface irrigation and one ofthe most difficult parameters in practical field determinations. The infiltration equations are used todescribe water flow hydraulics and surface irrigation systems design. But determination of theparameters in these equations are costly and time consuming. Therefore, some estimating methods ar...

discrimination between iron deficiency (ida) anemia and β-thalassemia trait (β-tt) is a time consuming and costly problem. because, they have approximate similar effects on routine blood test indices, in some cases, the complementary tests, which are expensive and time consuming, would be needed for differentiate the anemia. complete blood count (cbc) is a fast, inexpensive, and accessible medi...

Unsuccessful cementing operation can jeopardize the whole well construction process, resulting in further costly and time consuming repair operations. The quality of cementing job is dependent on the cement composition and its properties. Design of cement composition is based on the available geological condition, materials and technical situation at well location. The cement properties like fl...

Ayurvedic bhasmas are still prepared by the age old methods using earthen pots and cow dung cakes. It is a laborious and costly method consuming a lot of time. This paper deals with a modern method of preparation using electric Bunsen. It is a convenient, and cheap method consuming less time. Chemical analysis of the samples prepared by the both methods did not show much difference.

The increasing complexity of construction, along with its rapid development, as well as ambiguities and gaps in the legal terms governing constructions, lack of trust in the parties regarding obligations and regulations are the main reasons of disagreements in domestic projects. These disagreements are inevitable even in contracts which are set correctly. Disagreements are costly, time-consumin...

according to variety of accessible hydrological models, evaluateing the efficiency of models for different management objectives are essential. therefore, models with simple structure and using minimal input that can provide an acceptable result can serve as an effective tool to watershed managers. hence, the objective of this research is to evaluate the relative performances of the lumped conc...

Heliostat calibration is very time-consuming. It takes several months to calibrate the heliostat-field in a concentrated solar power (CSP) and thermal (CST) plant. Since particular heliostat cannot be calibrated often, it has keep its accuracy for months. Therefore, heliostats are manufactured robust sturdy, which makes installation costly. A possible solution issue of time change technique. Th...
