Today, due to the various usage of compression ignition engines in urban transportation, as well as the need to reduce exhaust emissions and control fuel consumption, the use of alternative fuels has become common in diesel engines. Gaseous fuel is one of the most common alternative fuels that can be used in diesel engines. The utilization of alternative fuels in compression ignition engines re...
: In this paper, in order to introduce manufacturing cost reduction methods, using a thermodynamic approach, the performance of cast iron rotary furnaces is analyzed. To do so, the furnace atmosphere is chosen as a control volume. Then, heat sources, heat sinks and heat loss mechanisms are recognized and the first law of thermodynamic is applied to the control volume. The analysis showed that r...
abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
this study investigated different concepts for natural-gas-fired power plants with the co2capture, and compared them based on the net plant efficiency and emission of co2. the cycles were based ona six oxy-fuel, one post-combustion and two pre-combustion capture concept. this paper presented theresults of an environmental evaluation performed by the application of the life cycle analysis (lca) ...
Due to increasing awareness of the deleterious environmental and health effects of diesel combustion emissions, major regulatory action and policy measures are focused on reducing emissions from diesel engines. Freight operations, including rail-based freight transportation, have received special attention as an industry where major change can be affected, especially in neighborhoods located ne...
This paper presents the evaluation of a new onboard system designed to reduce fuel consumption and CO2 production. GERICO system enables the driver to adopt the best driving behaviour, smooth speed and good gear management. We carried out 80 tests (40 baselines, 20 with training and 20 with GERICO) with 40 drivers in the Toulouse area. The main results show that training contributes to a 12% co...
The usefulness of [1-11C]acetate as a tracer of overall myocardial oxidative metabolism for use with positron emission tomography has been investigated in 12 closed-chest dogs. Myocardial 11C activity clearance kinetics after intravenous administration of [1-11C]acetate in dogs have been determined noninvasively by positron emission tomography. Biexponential fitting of regional myocardial 11C t...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
Technetium is one of the most important radioisotopes recognized in medicine which is obtained through the decay of molybdenum 99.The half-life of this radioisotope is 6 hours and it is capable of 140 kev gamma ray emission. Due to its short half-life, this radioisotope must be produced at the site of consumption, so that the shortest possible time interval between production and consumption c...
