يستخدم العاكس القطعي المكافئ في الأنظمة الصوتية الموجهة، و ذلك بهدف الحصول على التوجيهية، إضافة إلى زيادة الربح في الإرسال و الاستقبال. لذلك فقد تم إجراء دراسة نظرية لتوصيف العوامل التي تؤثر على ربح الطبق القطعي المكافئ في المجال الصوتي، كما تم الحصول تجريبياً على علاقة الربح بالتردد باستخدام طبق قطعي مكافئ ذي فتحة إهليليجية، إضافة لتحليل العوامل التي أدت إلى انحراف العلاقة التجريبية عن العلاقة النظرية.
The parabolic reflector is used in directed acoustic systems, with the aim of gettingdirectivity, as well as increasing the gain in transmission and reception. Therefore, a theoretical study was carried out to describe the factors that affect the gain of the parabolic dish in the acoustic field. The frequency-gain relationship was experimentally obtained using a parabolic dish with an elliptical aperture, in addition to the analysis of the factors that led to the deviation of the experimental relationship from the theoretical relationship.

Usually, a reflector dish with a loudspeaker or a microphone placed at
its focal point is used in directed acoustic systems to determine the
direction in which the acoustic wave is transmitted or received, in
addition to improve the gain in the ac
oustic transmission or reception.
As the parabolic reflector dish with an oval aperture has significant
advantages, and there is no relationship between parameters of this dish
and some variables that have direct influence on acoustical emission or
reception of this dish, this work is intended to find this relationship, and
this is achieved by carrying out a theoretical and experimental study to
find the optimum utilization of this dish in directed acoustic systems.
Solar radiation which reaches the earth surface in Palmyra city has high rates, so we introduce this research to study the operation of a solar electric power plant with parabolic trough solar collector type. Electric power plants are usually designe
d to operate at nominal design power and flow rate, pressure, specific steam temperature. In this case the obtained efficiency is relatively high, but the real conditions in which the plant operates and supplies the electric grid, in addition to the climate variations during monthes and seasons, all lead to a deviation in power value from nominal value, so the plant operate at partial loads. We used the analytical method in this research to study the variation in power plant parameters as the steam turbine load changes. In other words, the study of main plant parameters variation due to variable partial loads. We calculated steam pressure variations through turbine stages and its effect on changing steam flow rate to the recovery water heaters. In addition, we calculated the amount of heat consumed through turbine unit, turbine unit efficiency, and the total efficiency of the power plant.
In this study, several samples of a common polymer (aniline-phenolformaldehyde)
we prepared by condensation polymerization method based
on aniline, phenol, formaldehyde and in the presence of a catalyst of
ammonia solution at different concentrations.
The present research aims at synthesizing micro-porous and fluorescent polymer by microwave assisted synthesis allowing to reduce preparation time of 3 days at 180 °C using conventional method.
The Arabic Alphabet is considered the first linguistic lesson
presented in a certain language to announce itself. The Arabic Alphabet
has been a chant for all generations since the second century BC. This
study is investigating some secrets for arranging these letters as well as
explaining their forms.
