Leachate originating from open refuse dumpsite systems can be delineated through an integration of qualitative and quantitative methods. This study was designed to examine extent of leachate and pollution from one of the numerous open refuse dumpsites in Lagos metropolis. Qualitative assessment was determined using electrical resistivity tomography (ERT), vertical electrical sounding (VES) and ...

An important advantage of using a short-term pre-aeration of municipal solid waste (MSW) with high organic fractions prior to landfilling is that it intensively decomposes a part of organic matter, especially easily biodegradable fractions in waste, and thus regulates the subsequent anaerobic degradation of MSW under landfill conditions, meanwhile conserving the bio-methane potential as much as...

Abstract This review assesses the leachate quality from waste disposal sites in tropical climate zone. Through this review, data 228 samples 145 18 countries region were analyzed. The 12 types of considered for analysis based on climatic conditions, age, and operating condition site. Tropical rainforest, monsoon, savanna climates identified zone classification. Age site was classified as young ...

This paper describes the application of life cycle assessment for evaluating various waste management options in Singapore, a small-island city state. The impact assessment method by SimaPro is carried out for comparing the potential environmental impacts of waste treatment options including landfilling, incineration, recycling, and composting. The inventory data include gases and leachate from...

Labile plasma iron (LPI), a non-transferrin-bound component of plasma iron detected in iron overload disorders is a potential source of cellular iron accumulation and ensuing oxidative damage. Periodic monitoring of LPI over a 24 h time-span was used to compare the ability of chelation to control daily LPI levels in 40 Thalassaemia major patients (9-11/group) who had been receiving one of three...

Lysinuric protein intolerance (LPI) is one of a group of genetic diseases in which intestinal absorption of the diamino acids lysine, arginine, and ornithine is impaired. In LPI, the clinical symptoms are more severe than in the kindred disorders. The mechanism of lysine absorption was, therefore, investigated in vitro on peroral jejunal biopsy specimens in seven patients with LPI and 27 contro...

Purpose. To quantify changes in anterior segment (AS) parameters after laser peripheral iridotomy (LPI) using AS-optical coherence tomography (OCT) of iris bombe. Method. AS images of eight eyes were captured before and after iris bombe and more than 2 weeks after LPI (post-LPI) using AS-OCT. We compared the following AS parameters: anterior chamber depth (ACD), anterior chamber volume (ACV), i...

BACKGROUND/AIM Cardiovascular morbidity and mortality are markedly increased in chronic renal failure (CRF). The aim of this study was to evaluate lipid parameters and bioindices in patients with different stages of CRF. METHODS In 46 hemodialysed (HD), 50 CRF patients with II, III and IV stage of CRF (non-HD) and 48 control subjects triglycerides (TG), total cholesterol (C), HDL-C, urea, cre...

GPR55 is a seven transmembrane G protein-coupled receptor and was originally identified as a putative third cannabinoid receptor. Recently, lysophosphatidylinositol (LPI) was reported to be a GPR55 ligand. Stimulation of GPR55 by LPI activates G(12/13) and G(q/11) proteins, induces phosphorylation of the extracellular signal-regulated kinase and increases intracellular calcium concentration. Ly...
