The performance of biofuel cells (BFCs) depends on the number electrons that can be harvested from one fuel molecule by bioanode, as well many other factors. Regular, one-enzyme bioanodes usually harvest two per molecule, lowering conversion efficiency chemical energy stored in to electrical energy. In this study, we successfully develop a high-performance BFC with two-enzyme bioanode four oxid...

Background: The preexistence of obesity with nutritional anaemia is becoming an increasing problem in the Eastern Mediterranean Region (EMR). Much controversy exists around the role of continued breastfeeding in alleviating the health and survival consequences of these problems in the region. Aim: To examine trends and relationships of nutritional anaemia (NA) in women and children underfive ye...

The popularity of social networking on the web and the explosive combination with data mining techniques open up vast and so far unexplored opportunities for social intelligence on the Web. A network community is a special sub-network that contains a group of nodes sharing similar linked patterns. A social network can be defined as a graph G = (V, E), where V = {v 1 , v 2 , v 3 , ....,v n } is ...

Background: There is great concern in the world about worker stress and quality of life, since a significant number companies show that physical mental suffering are one main causes absenteeism, generating high business costs due to low productivity. Stress at work ends up affecting not only professional income but also your health. Objective: To investigate correlation between level heart rate...

Loose sands (siliceous, silty, and calcareous classes) are extensively found near arid areas in Egypt. Furthermore, many geotechnical structures, like water channels roads, may be constructed on weak or loose sand soils. The behavior of is usually connected with different interdependent problems, such as high permeability, low shear strength, bearing capacity, seepage, stability. This work char...

Hormone-sensitive lipase (HSL) catalyses the rate-limiting step in adipocyte lipolysis. Short-term hormonal regulation of HSL activity is well characterized, whereas little is known about the control of HSL gene expression. We have measured HSL mRNA content of 3T3-F442A and BFC-1 adipocytes in response to the cAMP analogue 8-(4-chlorophenylthio)-cAMP (8-CPT-cAMP) and to the phorbol ester phorbo...

This study focused on the generation of electricity from whey in a bio-fuel cell (BFC). Whey or Milk Serum is the liquid remaining after milk has been curdled and strained. It is a by-product of the manufacture of cheese or casein in Foods and Sweets Company. It was selected as electrolyte in biofuel cell due to containing higher amount of branched-chain amino acids (BCAA's).The pH value of fre...

This paper investigates the effectiveness of two zeolites with different reactive silica content, fly ash (FA), blast furnace slag (BFC), silica fume (SF), and micronized calcite (MC) in reducing expansion of concrete due to alkali-silica reaction. Also in this research, effects of three different cement usages were investigated by using accelerated mortar bar method, ASTM C1260. Five different...
