It is well known that mold and casting table maintenance has a direct impact on the internal quality and surface quality of billets. In this paper, the evolution of the main key performance indicators (KPIs) associated with the main consumables of the Wagstaff Air slip billet casting technology is shown, such as molds, casting rings, transition plates and thimbles. The strategies taken to preserve a high standard of quality whilst monitoring the associated costs, are discussed. An automated Mold and Casting Table Maintenance Management system has been developed in house to make available the relevant information from the casting table servicing at the casting pit and at the mold room. A case study is described where this tool allowed us to reduce costs, keeping a high quality standard of the casting table maintenance, ensuring the internal quality of the final product.

It studied the geological properties and contamination characteristics of soil from contaminated sites of typical chromate plants in western plateau of China. The results indicated that in the shallow part of 0-4m, it was mainly loess-like soil and in the depth of 4-18m, it was mainly gravels and pebbles. The soil had better permeability and ex-situ washing treatment is recommended. The soil was severely contaminated and the concentration of chrome (Ⅵ) was as high as 16,000mg/kg. Based on the analysis, it developed a two-stage demonstration project of countercurrent ex-situ washing plus chemical stabilization with daily capacity of 20m3 soil and a demonstration project of chemical reduction and precipitation plus advanced treatment of filter bed with daily capacity of 200m3 wastewater. After treatment, the concentration of chrome (Ⅵ) in soil was less than 100mg/kg and that in water was reduced to below 0.05mg/L from 1,000mg/L, which can meet the requirements of third-grade groundwater quality standard.

Abstract The objectives of this study were to investigate the ability for ion-exchange (IX) to control trihalomethane (THM) formation, and to act as a potential treatment addition (upgrade) to a conventional treatment plant in Rainy River Ontario, Canada. The primary goal was to investigate the total organic carbon (TOC) and trihalomethane formation potential (THMFP) removal as a function of resin dose; and note the relative improvements over current conventional plant operation. IX resin (DOWEX TAN-1, Purolite 502P and 860, and Amberlite PWA9) removed 68–72% of TOC and 30–40% THMFP from the conventionally filtered water. Fixed-bed fluidized bed contactor was used to investigate the TOC/THMFP breakthrough for the DOWEX TAN-1 resin. Complete resin breakthrough occurred followed by 1,275 and 1,075 bed volumes for TOC and THMFP, respectively. Breakthrough output following 1,000 treated bed volumes was noted as the point at which THMFP levels reach the 0.1 mg L–1 water quality standard threshold required by Canadian regulators. High exchange capacities were recorded for the TAN-1 (3.02 mg mL–1) and PWA9 (2.03 mg mL–1) resins – both of which contain styrene backbones. The results produced in the bench-scale experiments were used very successfully in a full-scale upgrade of the Rainy River water treatment plant.

Evaporation of gasoline at gas stations is the origin of air pollutants in gas station environment. This study is intended to estimate BTEX emission levels at gas stations and mapping BTEX emissions at all gas stations in Semarang. 4.09 D Tank Program with supported data collected by survey and secondary data used to calculate the estimated emissions. We also measured BTEX levels in the gas station location sample with charcoal tubes as adsorbent and PCXR4 mini pump sampler. The emissions from dispensers and storage tanks in gas stations have different emission characteristics. The amount of emissions from dispensers for VOC pollutants is 3.9261 tons/year and benzene is 0.0561 tons/year (case study UNDIP gas station). While the emission from a storage tank for VOC pollutants was 232.91 tons/year, benzene was 1.79 tons/year, toluene was 33.36 tons/year, ethylbenzene was 0.39 tons/year, and xylene was 1.43 Tons/year. The estimation results of the model with the results of direct BTEX measurements in the field showed that the field measurement results were smaller than those estimated. Some assumptions used in the calculations contribute to estimating uncertainty. The measured BTEX concentration still meets the quality standard (Minister of Manpower and Transmigration Regulation No. 13 of 2011).

The development of new bio-based diesel substitutes can improve their compatibility with diesel engines. Nevertheless, for actual implementation, their environmental and economic performance needs to be studied. This study quantified the eco-efficiency of three bio-based diesels, viz., fatty acid methyl ester (FAME), partially hydrogenated FAME (H-FAME), and bio-hydrogenated diesel (BHD), to address the perspective of producers as well as policymakers for implementing the advanced diesel alternatives. The eco-efficiency was assessed as a ratio of life cycle costing as the economic indicator and three different environmental damages—human health, ecosystem quality, and resource availability. The eco-efficiency of FAME was the most favorable among all the potential substitutes with regard to human health and ecosystem quality, but the least favorable for resource availability impact. Even though BHD was beneficial in terms of life cycle costing, it was the least preferable when considering human health and ecosystem quality, though it performed the best for resource availability. H-FAME was also promising, in line with FAME. It is suggested that the technologies for BHD production should be improved, especially the catalyst used, which contributed greatly to environmental impacts and costs.

Quality control of traditional Chinese medicines (TCMs) used clinically is becoming a challenge and has limited the development of TCM due to the high variability in concentration levels of active ingredients and markers as well as the lack of well-established criteria. Using Shengmai injection, which is a well-established TCM, as an example, we developed an integrated profiling approach that simultaneously captures the entire spectrum of ingredients and quantitatively determines the levels of seven key ingredients in the TCM product. A multivariate statistical model was constructed to establish a “seven-marker-” based quality standard that qualified the majority of samples in this study. This newly developed strategy showed that a panel of key ingredients or markers in the TCM product were relatively consistent within a statistically acceptable range. Therefore, this metabolomics-based approach will complement the current quality control standard using the concentration of several key ingredients or their total content and help improve the consistency and clinic efficacy of TCM products.

Improving software process to achieve high quality in a software development organization is the key factor to success. Bangladeshi software firms have not experienced much in this particular area in comparison to other countries. The ISO 9001 and CMM standard has become a basic part of software development. The main objectives of our study are: 1) To understand the software development process uses by the software developer firms in Bangladesh 2) To identify the development practices based on established quality standard and 3) To establish a standardized and coherent process for the development of software for a specific project. It is revealed from this research that software industries of Bangladesh are lacking in target set for software process and improvement, involvement of quality control activities, and standardize business expertise practice. This paper investigates the Bangladeshi software industry in the light of the above challenges. doi: 10.3329/jbas.v32i2.2432 Journal of Bangladesh Academy of Sciences Vol.32(2) 2008 131-141
