– the normal and lateral line cycloid scales of a cyprinid fish capoeta damascina (valenciennes incuvier and valenciennes, 1842) have been subjected to the scanning electron microscopy technique in orderto study their detailed structure. the scales have the general morphological characteristics of the cycloidscales. in the normal scale located below the dorsal fin, the focus lies towards the an...

conclusions our method provided good results and performing evacuation under the guide of bedside ultrasonography is recommended. results we treated 173 patients, including 164 females (94.8%), with the mean (sd) age of 43.75 (10.62) years. according to vas, 95.4% of patients reported complete satisfaction while 2 (1.2%) were unsatisfied with the results. patients reported no complication of th...

Sulfate scale deposition (BaSO4, CaSO4, and SrSO4) is a common problem in oilfield operations around the world, which causes significant formation damage during production and injection activities. This paper presents the results of an experimental study on the permeability reduction of porous media due to sulfate scale deposition. A set of experiments were cond...

This paper proposes an alternative approach for efficiency analysis when a set of DMUs uses interval scale variables in the productive process. To test the influence of these variables, we present a general approach of deriving DEA models to deal with the variables. We investigate a number of performance measures with unrestricted-in-sign interval and/or interval scale variables.

The use of amalgamation process to recover gold from mined ores by the small-scale gold miners in the Philippines and other developing countries produces and dispose of untreated wastewater to the receiving water bodies. In this study, a field-scale filter bed system was constructed to treat heavy metal metal-laden wastewater collected from small-scale gold mining site in Paracale, Camarines No...

Homogeneous turbulence and in scale-by-scale equilibrium, played a leading role the research of second half twentieth century, Jack Herring was an important contributor to these developments. The activity which has followed developments over past ten fifteen years concerns turbulence, is out equilibrium either because it non-stationary or non-homogeneous both. This paper short review recent pro...

the available experiments and reports of executed projects in iranian research centers and universities show that the ability of know-how development of chemical and petrochemical synthesis as well as their required catalyst is existed in laboratory scale. although, know-how development in larger scale is possible, too but no certain scientific and classified method has been explained which is ...
