عرضت في هذا البحث طريقة عامة للحساب الحراري لمبخرات و مكثفات محطات التبريد، تعتمد على استخدام الطريقتين: التحليلية - البيانية و طريقة التكرار، بحيث يمكن التوصل إلى حساب المقاومة الحرارية العامة. و يجري من خلال هذه الطريقة تبسيط آلية الحساب، و أحيانًا الاستغناء عن اتباع العمليات الواجب إجراؤها في طريقة التكرار. كما تم الحصول على جداول و منحنيات يمكن استخدامها في الحساب الحراري عند أي تغير لبارامترات المبادلات الحرارية و ذلك بحسب نوعها.
The main purpose of this paper is to introduce a general approach to calculate the heating load of evaporators and condensers in refrigeration plants. This approach is based on both analytical-graphical and iteration methods. The general heat resistance has been calculated by easier and less complicated procedures. Heat load in any heat exchanger is obtained using produced tables and graphs according to the exchanger type.

Oleic acid is a fatty acid known as omega-9, which is found naturally in many plant
sources and animal products and is found in the form of tri-glycerides (oleic acid esters). In
this research, the oleic acid was isolated and purified with a high d
egree of purity up to
99% of the fatty acids extracted from olive oil, corn oil and palm oil with a yield of at least
87% of its percentage in the oils used by the use of crystalline urea as well as crystalline
selective cooling . GC-FID was also used for direct quantitative analysis of oleic acid and
other fatty acids.
The aim of this study is investigate in using refrigerants mixtures as substitute to
R134a in a testing compression refrigeration cycle designed to work with a mass of 100g
of R134a without make changing or modification in the cycle. The new mixtur
e that made
it is ozone-friendly, safe for using and consists of R134a, propane R290, butane R600, we
use three various types of this mixture and the coefficient of performance (COP) and other
properties was compared with R134a on the same conditions and on different evaporation
temperature. The results shows the refrigerant mixture (M40) has higher coefficient of
performance (COP) than that of R134a by about 7.77% and increasing the refrigeration
effect about 30% and decreasing the discharge temperature from compressor 3.2%
compared with R134a.
This study support possibility of using refrigerant mixtures in refrigeration cycle that
designed to work with pure refrigerant (single component) without making any change in
the cycle also it support the possibility of using refrigerant that have an excellent
thermodynamic properties and environmentally friendly like Propane and butane but there
are some warning from using it because their flaming.
In order to calculate the cross curve of stability related to ship form the water line
of equal volume corresponding to each load draught should be determined. Therefore
complex and long steps of mathematical calculations should be done for each ve
ssel
displacement.
The goal of this research is to build a mathematical model enables the determination
of cross curve of stability related to ship form for all ship displacements. This model is
based on reading of the transverse sections of the ship projected on to a vertical transverse
plane of the body plan.
This method does not need to previous assumptions to perform calculations therefore
the calculations accuracy could be increased in comparison with other methods currently in
use to evaluate the transvers stability for ships.
The efficiency of this method has been proven in saving time as well as in giving
good results by comparing it with the analytical results for ships of box and trigonometric
forms. The comparison includes Pozduinin approximate method which is largely used in
ship world as well as the stability curves for real commercial ship. The good results of
evaluation of cross curves of stability by the proposed method (scanning sections method)
allow to generalize its use for validation of ship stability and other works research.
In this work, we have found exact traveling wave solutions for generalized Fitzhug-
Nagumo equation with arbitrary constant coefficients, by using the homogeneous balance
method, The obtained results shows that these solutions changes with the spec
ials solution
of Ricati ODE with arbitrary constant coefficients , and shows that this method is simple,
direct and very efficient for solving this kind of nonlinear PDEs, It can be applied to
nonlinear PDEs which frequently arise in engineering sciences, mathematical physics and
other scientific real-time applications fields.
This experiment was conducted at Kharabo farm, Faculty of Agriculture,
University of Damascus. A total of 252 chicks of Japanese quail breeder females
were distributed on the first day of life into two groups, Gicks in G1 were
reared from 1-28 day
s of age under ideal required temperature according to
their age, while chicks in G2, were subjected to heat stress from 8 am to 5 pm at
42 °C from the first day of hatching until 28 day of age and to the ideal
required temperature from 5 pm until 8 am. Chicks of each group were
distributed into three subgroups, with three replicates per subgroup.
