Clean water is becoming one of the most scarce and valuable resources in the twenty first century as its supply is finite and its traditional source is easily polluted by industries and population growth. Existing and traditional wastewater treatment methods are expensive and in most cases are either impractical or unsuitable for smaller communities and certain industries. The Vetiver System wa...

The outbreak of COVID-19 has brought huge impact on Chinese economy and society, including the development country’s logistics industry. This paper focuses analyzing whether China Logistics Prosperity Index (LPI) a relationship with cases cumulative vaccination rate respectively. Correlation tests are conducted in IBM SPSS Statistics 23 to analyze between monthly new LPI, additional doses per 1...

This study aims to investigate the impact of MSW landfill on the contamination of phthalate esters (PAEs) in nearby environment. Landfill leachate, surface water, groundwater and soil profile samples were collected from a MSW landfill area in Wuhan, China. Contents of 16 PAEs were detected for each sample using gas chromatography method. Results showed that landfill had an obvious effect on the...

In this study, five different experiments were conducted over a period of 170 days to produce biogas by using a variety of mixtures of organic materials and landfill leachate. The aim of this study is to develop a more robust two-stage biogas plant that can accept a wide spectrum of waste products and continue to function without any malfunction. The facility has 5m3 total digester volume, with...

introduction landfilling sites of wastes including big volume of waste. in recent years lack correct management caused that landfilling sites of municipal waste taken as one of main source pollution effluence at environmental. from between diverse contaminants heavy metals because of environmental stability, biogeochemical process, poison biology, sorption and desorption, redox potential, sedim...

In this study, movement of phosphorus pollution which is leachate to groundwater was investigated in Seri Petalling Landfill. Visual MODFLOW was used to predict subsurface and surface migration of pollution within 10 years. The results of sample analysing of phosphorus has shown its concentration in place of landflill was 2.38 mg/l since the National Water Quality Standard for Malaysia defined ...

PURPOSE To compare conventional laser peripheral iridotomy (LPI) and LPI combined with laser peripheral iridoplasty in eyes with primary angle closure suspect (PACS) by assessment of anterior chamber dimensional changes using a Pentacam. METHODS Forty-eight eyes of 24 subjects with bilateral PACS were recruited consecutively. Each eye was randomly allocated to treatment with conventional LPI,...

The present study is aimed at characterizing the landfill leachate as well as its impact on the surrounding groundwater in Kolkata, India. Landfill leachate has been seasonally characterized from 2012-2014, indicating the landfill site in methanogenic phase with high contamination of organics, nutrients, salts, and heavy metals. Sixty groundwater samples have been analyzed for twenty two physic...
