twenty four cowpea varieties were raised at niab and arri, faisalabad selected for plant height (42-136cm) days taken to 95 % flowering (62-79 days) and for diseases resistance (0.67-7 rating). infestation was maximum on it-97k-461-4, 1068-7, it-97k 1042-8 and it-98k-558-1 and was graded as susceptible. maximum grain yield was recorded in elite (649 kg/ha) and lowest grain yield was observed in...
accurate prediction of municipal solid waste’s quality and quantity is crucial for designing and programming municipal solid waste management system. but predicting the amount of generated waste is difficult task because various parameters affect it and its fluctuation is high. in this research with application of feed forward artificial neural network, an appropriate model for predicting the...
Background and purpose: Proper and efficient management of hospital wastes because of its infection potential and possession of dangerous wastes is inevitable and this goal can be achieved only when we have a good understanding of the quality and quantity of hospital wastes and enough available information about separation, collection, treatment and disposal of hospital wastes. The aim of this ...
Background and purpose: Physical analysis of solid waste is the first step in waste management. In Iran, no data is available about rural solid wastes in the country. The aim of this study was to determine qualitative and quantitative analysis of rural solid wastes in Iran. Materials and methods: In this cross-sectional study, the data for national rural solid waste in 2012 was obtained from...
Building industry as one of the greatest industries in Iran comprises a significant share of waste generation in the country. Since a large quantity of the generated construction waste is buried due to the lack of a recycling protocol, it leads to an undesired waste of resources and causes severe environmental issues. This paper provides a study on the problem of material loss/construction wast...
Introduction: The proper management of hospital waste due to environmental pollution and nosocomial states has important role in promoting community health. One of the most important design and implementation of a correct program for management of hospital waste is knowledge of the qualitative and quantitative values of hospital waste. This study aimed to determine the qualitative and quantita...
Municipal solid waste (MSW) characterisation across socioeconomic residents is necessary for planning sustainable solid waste management. In view of planning for Kumba municipality in the South West Region of Cameroon, three types of socioeconomic residents classified as low, medium and high income residential areas were randomly sampled. In each residential area, 32 households were sampled fol...

Background and Aim: Inadequate management of biomedical waste can be associated with risks to healthcare workers, patients, communities and their environment. In this study a comprehensive survey was conducted to obtain information on the management of solid wastes in Qom hospitals.Materials and Methods: Field visits were made to 2 private and 4 governmental hospitals to collect the required in...
BACKGROUND In recent years the generation rate of construction and demolition waste (C&D) has significantly augmented. The aim of this study was to assessed the quality and quantity of construction and demolition waste in Tehran (capital of Iran). METHODS Questionnaire methods were used for estimating the amount of generated C&D wastes national statistical data and typical waste generation da...
