  Economic Growth in Japan after World War II was very remarkable and products from its manufacturing industry were widely accepted in the world market after productivity and quality of them were tremendously improved. On the other hand, Japan soon found itself in severe environmental deterioration, due to not being paid any attention to environment. However, that pollution from industry was removed rather promptly with help of quality control and everyone’s participation. Japanese economic growth depends much on the quality of products, which was improved initially by what was known by Statistical Quality Control (SQC), widely used in the U.S.A. Later on SQC was transformed to Total Quality Control (TQC) with small group activities named QC Circles by Japanese and with some modifications and/or from different approaches, Total Quality Management (TQM), Total Productive Maintenance (TPM), KAIZEN (improvement) and so on were created. These approaches were introduced and widely used among industries and other sectors in Japan as well as in other countries of the world. The basic philosophy which leads these approaches to success was everyone’s participation and continuous efforts for improvement. The aim of these methods were at first to improve quality and productivity, but emission of hazardous material was reduced quickly and environmental circumstances inside and outside of manufacturing sites were drastically improved as well by these activities. As the result, most of Japanese products are environment-friendly from manufacturing origin and have excellent Quality at the same time. In this paper, the philosophies of these TQC, TPM etc. and how they had effectively worked for pollution prevention and environment-improvement will be discussed with supporting result data.

  Separation of proteins from whey; namely α – Lactoglobulin and β – Lactalbumin was obtained using the bubble foam column technique. Two types of whey were conducted in this study; yogurt whey and cheese whey. The effect of gas flow-rate and the height of the whey (liquid holdup) inside the column were studied at room temperature and at constant pH of whey. Whey used here obtained from local dairy factory as waste, and was used to investigate the performance ability of bubble column to extract very low concentration portion from waste. Enrichment ratio showed that the possibility of extracting protein from whey was high. Results showed that enrichment ration was higher for yogurt whey from that of cheese whey. The results also showed that the efficiency of separation of these proteins increased with decreasing both the air flow-rate, and wheys volume inside the column. The maximum amount of protein obtained at air flow-rate = 0.2 Liter/ min at experimental condition.

  This study intends to analyze the metrological data like rain fall, temperature and humidity obtained from Jordanian metrological department, covering the period of 1955-2002. These obtained data were analyzed using the Geographic Information System (GIS) and converted into geographical maps. Three different parameters were investigated temperatures annual mean maximum and annual mean minimum, the average annual rainfall and the average annual relative humidity. The results show that no change in the average annual rainfall in both northern and eastern part of the kingdom, while it has been increases in the middle region of the kingdom. Although local temperatures fluctuates naturally, but over the past 50 years the average local temperature in Jordan has increased at very rapid rate since 1990 and it reached an elevation in temperature up to about 1.5-2°C. It is noticed that the global warming impact on Jordan weather has been started after the 1991, in which the phenomena of the global warming was noticed to have its impacts worldwide since that date. Due to the predicted increase in both maximum and minimum temperatures in some regions, the rate of evaporation will also tends to increase and hence higher relative humidity will be expected in that regions. The application of GIS in this analytical study was successfully used to analyze the data and to produce maps easy to understand the impact of global warming. GIS also helps to calculate the exact area where region experienced a change in temperature and or rain falls. This application will be the first in its application in Jordan at country level. The result will be in a great help for those in decision making in the field of environment.

  This study aims to investigate the effect of reactants and catalyst flow rates; the effect of the catalyst concentration and the position inlet to the reactor location of the catalyst on the synthesis of tert-amyl methyl ether (TAME), have investigated. The results reveal that the micro channel reactor shows high selectivity for homogeneous syntheses of TAME compared to heterogeneous ones. The experimental results show that no other di-ether products were noticed in this study. The selected flow rates for the reactants and the catalyst give a stable flow pattern inside the reactor and no turbulent flow was noticed in any conducted runs. The mole fraction for methanol (MeOH) and tert-amyl alcohol (TAA) are 22 and 37% respectively, (this was considered the standard condition). Experimental results show that, keeping H2SO4 flows in the top lane of the reactor gives good mixing from the middle and bottom lanes. At the same time this will give the chance to the reactant to be pulled toward the middle lane to promote the reaction. Therefore, the middle lane can be considered as the core of the reaction zone phase, while the other lanes as separation zones. On the other hand, when H2SO4 introduced from the middle inlet the chance of reactants mixing from the top and bottom lanes will be less. It was also noticed that during the reaction and when the H2SO4 introduced at the top lane of the micro-channel, the catalyst distributes itself within the TAA lane and forms a micelle to react with MeOH in the bottom lane. When the flow rates of the reactants was reduced to half of its standard condition the yield was noticed to be higher. This may be attributed to the fact that lower flow rate, will lengthen the residence time inside the reactor and more reaction will develop.
