introduction: we aimed to investigate of effect of left bundle branch block (lbbb) on perfusion and functional parameters in dipyridamole tc99m-mibi gated myocardial perfusion spect which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 70 patients with low pre-test probability of coronary artery disease in two groups:  35 patients with lbbb and  35 subjects...

introduction: we aimed to investigate the effect of right bundle branch block (rbbb) on perfusion and functional parameters in dipyridamole stress/rest tc99m-mibi gated myocardial perfusion spect (gspect) which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 73 patients with low pre-test likelihood of coronary artery disease in two groups:  38 patients with...

introduction: we investigated the difference in left ventricular ejection fraction (lvef) and end-systolic volume(esv) measured by gated myocardial perfusion spect (gspect) in the post-dipyridamole stress and rest periods, and compared the results with the perfusion patterns found in the conventional non-gated tomograms. methods: 297 consecutive patients were studied with post-stress and rest 9...

Hazardous waste (HW) management represents a central aspect of the environmental performance of industrial establishments in Egypt. In response to the need for monitoring this performance and the progress of industries in managing their HW, sets of HW indicators have been developed within the larger scope of environmental performance indicators for industry. The HW indicators address three them...

the construction industry is a major consumer of new materials. given that material production for construction work accounts for a significant percentage of all energy consumed nationally in newly developing countries, it becomes vital that the construction industry strives to reduce waste at all stages of construction. however, the importance of these construction wastes in terms of types and...

This study aims to present the effects of citizen participation on Integrated Solid Waste Management – ISWM, considering all stages of urban cleansing: solid waste production, collection, transport, treatment, recycling and final disposal, as well as to help decision makers and agencies involved in solid waste management in developing a policy that will utilize citizen participation as an impor...

The main work of this project is the characterization of household waste and its equivalent energy recovery of the household waste management in the urban areas. Primary and secondary data were used for the manuscript. In the total amount of the waste 87% is vegetable, 4% grass and wood, 1% plastic, 2% is paper and only 1% metal were found. The moisture content as discarded waste was found 68.0...

The population growth, changing consumption patterns, and rapid urbanization contribute significantly to the growing volumes of solid waste that are generated in urban settings. As the rate of urbanization increases, demand on the services of solid waste management increases. The rapid urban growth in Langkawi Island, Malaysia, combined with the increasing rates of solid waste production has pr...

background and objectives: hospitals usually generate large amounts of hazardous waste. if not managed properly, hospital waste can pose threats to public safety and damage the environment. waste minimization is a waste management approach that focuses on reducing the amount and toxicity of hazardous wastes. this study pursues a two-fold purpose: 1) to gain insight into hospital waste minimizat...
