انتشر استخدام الزجاج المزدوج بشكل كبير بما يحققه من عزل حراري، و بالتالي تخفيض في استهلاك الطاقة سواء في التدفئة شتاءً أو في التبريد صيفاً. دخلت صناعة الزجاج المزدوج في سوريا، و أصبح من الضرورة الملحّة تحقيق وفر في استهلاك الطاقة في عملية تصنيعه، و بشكل خاص في عملية تجفيفه قبل إجراء دمج لوحي الزجاج مع بعضهما، و إنتاج لوح الزجاج المزدوج. قام الباحث ببناء موديل رياضي للمبادل الحراري المستخدم في تجفيف ألواح الزجاج باستخدام برنامج Matlab، و تمّ من خلاله دراسة تأثير العوامل المختلفة على تصميم المبادل الحراري، بغية الحصول على التصميم الأمثل الذي يضمن تخفيض في استخدام الطاقة في عملية التجفيف.
The use of double glass has spread largely to achieve thermal isolation and reduce the consumption of energy in refrigerating in summer or heating in winter. The manufacture of double glass has entered in Syria, and become very important necessity for achieving gain in consumption of energy, and specially in the drying process of its before joining tow glasses together and making double panes. The researcher has prepared mathematical model for heating exchanger which is used in drying of panes by using Matlab program, and by this pattern the researcher has studied the effect of different factors on design of the heating exchanger for finding the optimal design which ensure reducing in using the energy in the drying process.

This search was carried out in order to generate electricity small capacities especially
in remote locations far from the electricity grid. the search includes a thermal analytical
study of mini radial turbine which represents the Expander in Organ
ic Rankine Organic
Cycle (EES).
In this search, the selection multiple parameters and study the effect of each
parameter on the outlet of the mini turbine using the program EES (Engineering Equation
Solver) was done using several working fluids to drive a mini turbine, and We have
conducted a comparison between them and determine the best impact on the outlet of the
mini turbine.
The objective of this study is to identify the basic characteristics of the organizational loyalty of the employees of ASIA and what factors affect the organizational loyalty of the employees. As well as the level of effect of these factors on the organizational loyalty of the employees of Asia.
Building a photovoltaic system is the process of designing,
selecting and calculating the ratings of the equipment’s employed in
the system. This process depends on a variety of factors such as
geographical location, solar irradiation, and load re
quirements. this
paper presents a practical way to calculate the elements and
components of the Stand-Alone PV energy system, And procedure
an economic analysis for the system, will allow GUI designed by
MATLAB knowledge of these components depending on the
efficiency of the Inverter, power solar panels and capacity of
batteries in local market, taking into account the climatic factors and
hours of solar radiation in the system installation area, as well as the
cost of the system and the payback time.
The design of milking spaces, which are called Mahlab, is considered as the main factor for many
experts in agricultural engineering and animal production. The main aim is to determine the optimum
parlour milking with highest production and little
stress, whereas the parlour milking is considered as the
most important design factor in the barn because it is Influences getting the milk in cattle productivity
farms.
According to the importance of milk production, which effects on the local production and economy, this
paper treats with the most effective factors in the design of parlour milking in cattle farms, in order to be
suitable for dairy cattle production by considering its numbers, its movement and its suitable space. So,
this reflects its impacts on the level of production, in addition it shows the most important type of parlour
milking in the world that reflects the advantages and disadvantages that determine the type and size of
required parlour milking and its location and relationship with the cattle barn.
The aim of this work is to study the flow behavior of white Vaseline "which
is used in pharmaceutical industry and Cosmetics" in statical state.
The study was carried out on the white vaseline in the molten state under
the effect of temperture, sh
ear stress (τ), and shear rate (γ) by using capillary
viscometer, then the corrections have been done to expermintal data. It was
found from the obtained results that, real viscosity decreased with increasing
real shear rate (γc). Also it was found that the vaseline is a pseudoplastic
material (n<1).
For determining viscous activation energy at constant shear rtae (Eγ) and
shear stress (Eτ), the relationship between real viscosity (ηc) and (1/T) was
studied. It was found that the viscous activation energy decreased with
increasing the shear rate and shear stress, where the value of viscous activation
energy reflectes the temperature–sensitivity of real viscosity.
Elastic properties for vaseline were studied by determining the die swell
ratio (B) (Barus effet), and it was found that (B) increased with increasing
shear stress, but it decreased with increasing L/R ratio, while the temperature
do not have any effect on (B). The time residence (tr) of vaseline in the die was
deterimined and studied the relationship between (B) and (tr).
Note: vaseline does not carry any kind of bacteria, because it is unsuitable
medium for their growth.
