The aim of the study is to develop a design an air-heating recuperator for purge ventilation system building inbuilt purpose utilizing lower-grade heat from gases and emissions with associated production thermoelectricity. An experimental as part unit has been developed. It includes thermoelectric source electromotive difference, which operates result conversion into electricity, allows lower-p...

Excessive heat losses and water consumption in cooling units are significant constraints restricting the application circumstances performances for SCO2 Brayton cycle, exchange capacity precooler (PRC) is typically 1.5 times that of power generation. Therefore, this research offers a high-integrated combined power/cooling system which two waste exchangers (WHEs) rectifier (RET) used instead PRC...

in this research, using the modified compression field theory (mcft), a new truss based model is proposed to predict the behavior of reinforced concrete coupling beams with diagonal reinforcement. the model is able to consider the effects of shear and axial forces and bending moment, simultaneously. the proposed model includes a nonlinear shear spring, an axial spring, two inclined truss member...

in this research, the possibility of using high percentage of lignocellulosic fibers in making natural fiber-thermoplastic composite was studied. three weight percentages of bagasse flour namely 40, 55 and 70 percents were chosen. mapp was used as coupling agent at two weight percentages of pp, namely 0, 4 and 6 percents. tensile strength was measured applying instron 6025. the results showed t...

a complete linear theory in four dimensional space-time is constructed for propagation and coupling of electromagnetic waves in the most general case, i.e. media where all three space directions are in homogeneous and where temporal changes, anisotropy and absorbtion are also included. the only condition is that the properties of the medium should be slowly varying, although it is assumed that ...

this study introduces the differential transform method (dtm) to analyse the free vibration response of a rotating, closed section, composite, timoshenko beam which features material coupling between flapwise bending and torsional vibrations due to ply orientation. the governing differential equations of motion are derived using hamilton’s principle and solved by applying dtm. the natural frequ...

In this paper, results from comprehensive thermoeconomic assessments of small-scale solar organic Rankine cycle (ORC) systems are presented based on weather data in London, UK, which is taken as representative a temperate climate with modest temperature changes, mild winters and moderate summers. The consider range of: (i) collector types (flat-plate, evacuated-tube, evacuated flat-plate collec...

The use of neuroprotective therapies begs the question of how such therapies could affect preexisting stem cell populations within the host, as well as those introduced through cell-replacement therapy. Multiple mechanisms may mediate stem cell responses to neuroprotectants such as host/donor age and gender, cellular lineage/differentiation status, and mitochondrial dynamics. Current therapeuti...

Hydronephrosis secondary to pelvi-ureteric obstruction affecting one hundred children and derived from a 13 year period were reviewed. Particular attention was paid to symptomatology in infancy and childhood, pre-operative investigations and postoperative assessment. Following pyeloplasty the late results assessed clinically, radiologically and renographically were entirely satisfactory. The op...
