in this research the effects of different levels of oily and aqueous extracts of chamomile flower on biochemical characteristics and quality of breast meat were examined. using 400 broiler chicken (cup 500) in to 5 treatments, with 4 replicates and 20 chickens per replicate chicken were daily treated with 85 and 128 mg per kg body weight aqueous extracts, and 14 and 21 mg per kg body weight of ...

Society must move towards an economy in which sustainability is its main driving force. A sustainable solution to avoid sending waste landfill, the consumption of raw materials and, therefore, depletion natural resources, reuse or recycling waste. Here, pavement engineering has great potential, as can be used for manufacture bituminous mixes. In particular, one these residues Marpol, generated ...

Inhibition of the respiration microbial activity in the activated sludge caused by heavy metal concentrations (Cr, Cd, Cu and Ni) was studied by means of respirometric method using Strathtox respirometer (Strathkelvin Glasgow).The studied sludge samples were obtained from the two waste water treatment plants with different types of pollution (municipal waste water and domestic waste water). Key...

Urban planning includes land use management and environmental change. It makes arrangement for community facilities and services. Since, sustainable development has been included as a vital end product of all planning goals it also provides for balanced use of land, housing and transportation and better quality of life. Present urban planning in Pakistan is not ensuring sustainable development ...

BACKGROUND In the sub-urban areas of Kampala city, springs are a major source of water for domestic use. Though spring water is considered to be aesthetically acceptable for domestic use, presence of poorly designed pit latrines, poor solid waste management as well as poor and inadequate spring protection, may lead to contamination of spring water with pathogenic bacteria. OBJECTIVES The obje...

• Waste cooking oil was considered as feedstock for biodiesel production. Kinetic data were derived from actual WCO samples avoiding model components. Aluminum chloride hexahydrate is a promizing catalyst the esterification step. Reactive distillation with alkali used transesterification. In this work, novel method proposed conversion of waste into biodiesel. A two-step approach based on pretre...

aims: the effect of electrochemical process on polyphosphate alone has not been yet investigated. the aim of this study was to study polyphosphate removal from synthetic wastewater by electrochemical process.  materials & methods: this research was carried out experimentally on 50 samples of synthetic wastewater. in each run 2000ml of sw took place in a batch. a constant 600ma direct current wa...

The separation process of oily water using membranes has attracted the attention researchers and engineers. greater problem in use membrane is reduction permeate flux due to clogged pores by oil deposition inside or effect concentration polarization. For this purpose, a theoretical study water/oil module was performed. This device consists tubular ceramic provided with rectangular inlet section...
