this research covered three villages in kura local government area of kano state. the study described the socio-economic characteristics of maize producers and their production techniques and also determined the profitability and resource use efficiency in the maize production. structured questionnaires were used for primary data collection and 40 small scale producers were purposively selected...

– 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...

It was pointed out by Trowell, Davis, and Dean (1954) that, 'Nothing is known about the completeness of recovery from severe kwashiorkor', and this is to a large extent still true. An increase in the body weight is admittedly a sign of recovery, and indeed a very important criterion of it, but unless the final weight and height attained are also known it is impossible to say whether it has been...

There are few reports of alkaline phosphatase activity in the serum of children suffering from kwashiorkor. The values quoted are somewhat conflicting: Waterlow (1948) found an average level of 19.7 .King-Armstrong units in eight cases of "fatty liver disease " in Jamaica, and Jaya-sekera, de Mel, and Cullumbine (1951) reported an average value of 15.8 units in 40 children with kwashiorkor inve...

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...
