escalating development of tourism and petroleum industries in small islands such as lavan-iranrequires sound solid waste management. in the present investigation, three scenarios which consist of thecombination of landfill, recycling, incineration and composting and their environmental impacts have beenevaluated for 7514 kg/day of waste generation in lavan island. for this purpose, life cycle a...

in this study a pseudo comprehensive carbon footprint model for fossil fuel power plants is presented. parameters which their effects are considered in this study include: plant type, fuel type, fuel transmission type, internal consumption of the plant, degradation, site ambient condition, transmission and distribution losses. investigating internal consumption, degradation and site ambient con...

In today’s competitive market, production costs, lead time and optimal machine utilization are crucial values for companies. Since machine or process breakdowns severely limit their effectiveness, methods are needed to predict products’ life expectancy. Furthermore, information about the remaining life of products and their components is crucial for their disassembly and reuse, which in turn le...

This paper presents a two-stage integrated approach to assess the reliability of components for reuse in the second life cycle. Statistical data analysis, the first stage of the proposed method, determines the mean life of components by analysing the time-to-failure data for an electric motor and gearbox of a washing machine. A well-known reliability assessment method, Weibull analysis has been...

OBJECTIVE: The overall objective of this research study was to explore the current conditions and state of the art in management of asbestos cement (AC) water main assets and develop a practical, comprehensive guidance manual to be used by the owners of these assets. Issues to be addressed included pipe deterioration and failure, condition assessment, remaining service life prediction, rehabili...

ACCORDING TO THE EJECTION FRACTION, PATIENTS WITH HEART FAILURE MAY BE DIVIDED INTO TWO DIFFERENT GROUPS: heart failure with preserved or reduced ejection fraction. In recent years, accumulating studies showed that increased mortality and morbidity rates of these two groups are nearly equal. More importantly, despite decline in mortality after treatment in regard to current guideline in patient...
