BACKGROUND A previous two-year study of continuous and on demand bronchodilator therapy in patients with moderate asthma and chronic bronchitis showed a deterioration in lung function in those on continuous therapy. AIM A two-year follow-up study was undertaken of patients who had been shown in the previous study to have non-steroid dependent (mild) asthma and chronic bronchitis, in order to ...

Inflow and Infiltration (I/I) is extraneous water that enters a sewage treatment plant via groundwater infiltration or direct stormwater entry into sewers. This study is an attempt to quantify I/I impacts based on an assessment of influent and effluent data from twenty-four wastewater treatment plants (WWTPs) in Georgia with design capacities of 37,850 m/d (10-mgd) or greater. Twelve-months of ...

The purpose of this study was to investigate the photocatalytic oxidation of a reactive azo dye and determine the improvement in the biodegradability when photocatalytic oxidation was used as a pretreatment step prior to biological treatment. The results obtained from the experiments adding H2O2/TiO2 show that the highest decolorisation rate is provided by the combination of (UV+TiO2+H2O2). The...

This paper considers a two stages pharmaceutical supply chain (PSC) consisting of a pharmaceutical manufacturer (pharma-manufacturer) that supplies one type of pharmaceutical product to a pharma-retailer. The customer demand rate for the pharmaceutical product is dependent on the pharma-retailer’s current-inventory level. The pharma-retailer determines the order quantity ( ) value as decision v...

This study proposes a new multi-item inventory model with hybrid cost parameters under a fuzzy-stochastic constraint and permissible delay in payment. The price and marketing expenditure dependent stochastic demand and the demand dependent the unit production cost are considered. Shortages are allowed and partially backordered. The main objective of this paper is to determine selling price, mar...
