The research focuses on finding planning methods based on measuring and monitoring the
basic indicators of internal combustion engines (Diesel engines) in order to determine the
critical case of the engines, which determines the expected time for t
he engine or for some
of its basic parts to be sent for comprehensive maintenance.
The wear ratio of one of the basic components of the engine was also determined, we also
chose the diameter of the cylinder and the corrosion that happens to it in order to
determine the engine's lifetime and determine the moment when the engine should be sent
for comprehensive maintenance.
By observing a large number of engines put in repair in the industrial area in Lattakia,
which are 30 engines of different types of diesel and gasoline, and with different
capacities, it was noticed that about 15% of these engines were not exploited and invested
the entire work period designed for them. Also it was noticed that 20% of them have
stopped working because of the severe corrosion of parts, components and mechanics of
these engines, which led to their damage and their inability to do their work on a regular
basis. This has contributed to increased consumption of fuel and Lubricating materials,
which causes damage to the national economy.
The proposed planning method for determining the critical case of the engine when
comparing the schematic results with the practical results of the engines has proved its
efficiency and accuracy with an error rate of no more than 6% This allows it to be applied
and adopted as an effective way to determine the actual lifetime of the engine and compare
it with the life time of investing the engine mentioned in the manufacturer's catalogs when
operating the engine under normal conditions.
The research aims to find a way to calculate the hydrodynamic and thermal
characteristics of devices absorption foam used in the wet roads to clean the combustion
products of SO2 to increase the effectiveness of these methods and economic. For it h
as
been studied heat exchange and hydrodynamic device absorption with bilateral phase
moving layer (foam) with different models of contact devices, and on the basis of
experimental data and mathematical analysis have been obtained equations that allow
assessment of the impact of contextual factors in the core layer foam variables.
It was also stressed that the heat exchange in the field of foam layer is characterized
by high efficiency heat exchange between the gas and the liquid in the foam layer and
between the foam layer and the surface submerged, and give the temperature coefficient
depends on the initial conditions of gaseous and liquid phase and the temperatures of the
dew point of the gas and liquid teams at the entrance device absorption. As for the
effectiveness of cleaning the combustion gases from the cleaning degree of SO2 in the
upper border of the foam system up to (95,95%) on stage touches one.
The study also allowed increase reliability for wet cleaning system by selecting the
optimum poisoning and on the basis of data obtained.
The research aims to identify the level of the phenomenon of functional combustion with its dimensions (job exhaustion, low personal achievement, feelings of feelings) among workers in the financial directorate of Lattakia, and then study the effect
of the level of this phenomenon on achieving job satisfaction among workers in the directorate. The research relied on the descriptive approach, and the research community included all workers in the Lattakia Finance Directorate, which numbered (1083) workers, while the research sample was determined using the Statistical Sample Law, and the questionnaire was distributed to the sample's number of (284) workers, and was retrieved ( 251) Questionnaire, with a response rate of (88.38%). The results showed that there is a weak adverse and statistically significant effect of the job alienation of the employees in the financial directorate of Lattakia on achieving job satisfaction for them, as (32.8%) of the changes in job satisfaction were caused by the dimensions of the job alienation, and therefore the increased manifestations of job alienation among the workers in the financial directorate of Latakia They lead to a low level of job satisfaction.
The aimed of the research is to determine the role of career path dimensions through (training, promotion, incentives) in reducing job burnout (stress, and the limited work powers of workers at Tishreen University. The researcher relied on the deduct
ive approach as a method for thinking in formulating the research hypotheses and selecting the hypothesized relationships between the research variables, and the descriptive and analytical approach by listing Arab and foreign books and periodicals, and other publications related to the research topic, and reviewing, studying and analyzing them in order to answer the research objectives and discuss their hypotheses. As for the research methods, the researcher relied on the questionnaire as a tool for collecting primary data, and the questionnaire was distributed to a sample of 167 workers at Tishreen University, of which 164 were recovered, and 161 questionnaires were suitable for analysis. Then she analyzed the data on the dependent variable and the independent variable and tested the hypotheses using the analysis program. Statistician SPSS version 20 to accept or reject hypotheses. One of the most important results of the study was the content of the training program that is not commensurate with the needs of workers at work, and the training content is not determined on the basis of compatibility with the different abilities of the trainees, and the worker does not participate in choosing the appropriate work method and style, and the workers do not feel bored and bored because of my work.
Biodiesel can be produced from pure fatty acids or from frying oil wastes. To
optimize biodiesel manufacturing, many reported studies have built simulation models
to quantify the relationship between operating conditions and process performance.
