Important changes in technology and society, including the educational system, began and nourished the work. The preparation process formally commenced in August 1995 and has included educational, psychological, tactical and organisational means to attain the goal. Results from tests given to 36 entering freshmen of this class are presented and discussed in the paper. Project organisation and test results indicate that today's vocational schools may represent a future sector for the recruitment of new students into the engineering profession.

For Telemark University College (TUC) in Porsgrunn, senior year students' project works, which count for 1/6 of the student workload for that year, could represent such an opportunity. In this paper, the authors tabulate and examine some of the causes and effects of six off-campus senior year projects, with three of them having produced college revenues while the other three did not. The causes include the teacher' s role, students' competences and the human factor. The effects listed cover the technical outcomes, the college/partner relationship and college income. The study reveals that all projects tended to confirm former industry leader signals regarding a willingness to support the College economically if project work results were found to be useful for the company.

CO2 emissions from cement clinker production originate from decarbonation of limestone as well as fuel combustion, and the cement plants in Norway have to comply with requirements given by the pollution control authorities via the national emissions trading system. There are several ways of reducing CO2 emissions from the cement industry. Utilizing CO2- neutral waste fuels as a replacement for fossil fuels is an attractive means of reducing the net CO2 emissions. Using modern kiln technology is another important measure facilitating lower emissions. The Norcem plant in Brevik carried out an extensive modernization project in 2004-5, and as a result of this the plant in Brevik currently uses close to 100,000 tons of CO2-neutral wastefuels every year. The outcome of this is a reduction in fuel-generated CO2 emissions of about 25 % from 1995 to 2005. Reduction of CO2 emissions by secondary methods such as post-combustion measures using amine absorption for the capture of CO2 in the exhaust gas from the cement plant is technically feasible, but expensive and risky.

Thus, it is important to know how mercury distributes and behaves in the kiln system. The objective of the study was to measure the distribution of mercury in the kiln system, to measure the hold up time of Hg, to measure the portion of emission through the chimneys, and to see the dependence of the injection sites on these parameters. The results showed that the amounts of mercury being emitted through the exhaust gases were largely dependent on where it was injected. The residence time of mercury in the system was nevertheless long, after 10 hours it was still increase in the count rate of the mercury absorbed. There was also an immediate increase in the filter dust, but nothing could be measured in the clinker. This knowledge is needed for the reduction of mercury emissions. <br/> <br/>Description: The original publication is available at www.springerlink.com Sun, 29 Oct 2006 22:58:59 GMT
