Increasing competition in service businesses (eg: Information Technology, Healthcare, Education, Logistics, Distribution, Hospitality Financial and other services) is compelling corporates to adopt business improvement philosophies and methodologies for addressing customer demands for better quality service and organizational demands for improving the profit margins through cost reduction. Many companies around the world have already implemented Information Technology Infrastructure Library (ITIL) as a way to manage and control their Information Technology (IT) Departments more effectively. These companies are now willing to improve their ITIL processes in order to become even more efficient. Lean Six Sigma is a methodology that has been suggested as a means to resolve these problems, reducing costs and improving quality. Its application in the IT Services area is becoming increasingly popular among researchers and academicians and can be used to conduct these improvements. Despite the application of lean six sigma approaches to different contexts in the service sector, the application of Lean Six Sigma approaches in service delivery specific to Information Technology Service Management (ITSM) remains largely untested. The purpose of this paper is to implement Integrated Lean Six Sigma for Software application support services and evaluate the benefits of continual service improvement over ITIL.

Traditional thermal methods of drying food have often led to loss of flavours, nutrients, vitamins, etc., which encourages non-thermal pretreatments such as osmotic dehydration （OD） and/or high electric field （HEF） application to improve the overall product quality. The aim of this study was to evaluate the effect of osmotic dehydration （50% sucrose） with high electric field strengths of 0.5 and 1.0 kV/cm as pretreatments on the drying kinetics and mass transfer of green apples during convective drying at 65 ~C and microwave drying at 1 W/g. The added value of the OD and HEF on the drying kinetics, and the effective mass transfer coefficients of the subsequent drying methods were investigated through this research. The efficacy of these pre-treatments was assessed and compared using cell disintegration index, product texture and thus bring forth new correlations between these pre-treatments and the cell disintegration index using dielectric spectroscopy and its effect on the product texture.

亚麻原茎收获后需要经过水沤或雨露脱胶以制取纤维,但这2种方法耗时长、有污染,本文利用射频介电加热进行亚麻原茎脱胶。为研究射频脱胶方法,明确脱胶介质与功率、温度和处理时长对亚麻脱胶质量的影响方式,进行了3组对比试验,脱胶质量则通过脱胶效果和纤维力学性能两类指标进行综合评价。通过组内与组间麻茎失重率的分析得出,无水射频较有水射频脱胶会增加脱胶效果;并且不管何种脱胶介质,增加射频功率、温度和处理时长都会改善脱胶效果。通过亚麻纤维力学性能的比较分析得出,相比于原麻纤维,无水射频频脱胶后纤维的拉伸性能显著降低(P<0.05),而有水射频脱胶时增加温度和处理时长则有使拉伸强度增大的趋势。综合考量,亚麻原茎短时水沤后采用有水射频脱胶能够获得较优的脱胶质量,可以成为一种亚麻原茎绿色、高效的增值化处理方法。

The Lobo watershed is an agricultural area where the use of fertilizers by farmers is intensive, causing eutrophication problems that deteriorate the quality of drinking water distributed to the population. Since the phenomenon of eutrophication is directly linked to runoff, it is essential to model the flow in order to better control the transfer of nutrients responsible for eutrophication. It is within this framework that this study was conducted. The objective of this study is to assess the ability of the semi-distributed SWAT (Soil and Water Assessment Tool) model to simulate runoff in the Lobo watershed. The methodology adopted was based on the use of the QSWAT graphical interface to manipulate and execute the main functions of the SWAT model from QGIS tools. The hydrological modeling was carried out with the QSWAT interface for SWAT 2012. The results showed good performance for the flow calibration (1982-1984) with the evaluation criteria R2, NSE and PBIAS respectively of 0.64, 0.64 and 3.1. In the validation period (1984-1987), the model also showed good performance in the streamflow simulation for R2 and NSE of 0.84 and 0.76 respectively as values. However, for the PBAIS criterion, the result was less good but still remains satisfactory with a value of 19.6. It emerges from this study that the SWAT model is suitable for simulating water transfer and can therefore be used to study the transfer of pollutants in the fight against eutrophication in the Lobo watershed.

Nonpoint source pollution from agriculture is the main source of nitrogen and phosphorus in the stream systems of the Corn Belt region in the Midwestern *** eastern part of this region is comprised of the Ohio-Tennessee River Basin(OTRB),which is considered a key contributing area for water pollution and the Northern Gulf of Mexico hypoxic zone.A point of crucial importance in this basin is therefore how intensive corn-based cropping systems for food and fuel production can be sustainable and coexist with a healthy water environment,not only under existing climate but also under climate change conditions in the *** address this issue,a OTRB integrated modeling system has been built with a greatly refined 12-digit subbasin structure based on the Soil and Water Assessment Tool(SWAT)water quality model,which is capable of estimating landscape and in-stream water and pollutant yields in response to a wide array of alternative cropping and/or management strategies and climatic *** effects of three agricultural management scenarios on crop production and pollutant loads exported from the crop land of the OTRB to streams and rivers were evaluated:(1)expansion of continuous corn across the entire basin,(2)adoption of no-till on all corn and soybean fields in the region,(3)implementation of a winter cover crop within the baseline *** effects of each management scenario were evaluated both for current climate and projected mid-century(2046-2065)climates from seven global circulation models(GCMs).In both present and future climates each management scenario resulted in reduced erosion and nutrient loadings to surface water bodies compared to the baseline agricultural management,with cover crops causing the highest water pollution *** and soybean yields in the region were negligibly influenced from the agricultural management *** the other hand,both water quality and crop yield numbers under climate change deviated considerably f

以孵化4天(4dph)的黄颡鱼Pelteobagrus fulvidraco仔鱼为对象,通过15d的养殖实验,探讨养殖箱颜色对其存活、生长和鱼体生理指标的影响。实验鱼养殖在5种不同颜色(深蓝、黑色、亮绿、白色和褐色)的养殖箱中,以新鲜孵化的卤虫投喂。实验结果显示,不同养殖缸的背景颜色显著影响(P<0.05)了黄颡鱼仔稚鱼的存活和生长。养殖在深蓝色和黑色背景养殖箱中的黄颡鱼的成活率和增重最高;在亮绿和褐色背景中,鱼体的皮质醇(IRC)、葡萄糖和乳酸水平显著升高,而溶菌酶活性下降,这表明鱼体处在一种慢性应激状态。研究结果表明在黄颡鱼仔鱼培育阶段,养殖背景色非常重要,深蓝和黑色背景有利于提高黄颡鱼仔稚鱼的成活率和生长。
