The effect of two - mass system factors on the quality and quality of transient states , particularly the effect of mechanical rigidity has been studied in this research . Besides , mathematical expression which can calculate the optimal value of rigidity and provide the minimum extent of electromechanical vibrations have been obtained . Characteristics and schematic diagrams that prove the effect of mechanical rigidity on the behaviour of the transient state are illustrated . These methods help to improve the performance of automatic control systems in order to provide the minimum dynamic loads without reduction of the machine productivity.

The out-of-stability state of synchronous generator which
connected to high voltage network due to the transient
situations which lead us to disconnect the generator causes
finincial and technical problems. Therfore the purpose of this
research i
s to study the stability of synchronous generator
working which connected to high voltage network through the
transient situation.This research present the posibilty of
returning the synchronous generator to synchronous-steadystate
at the late time of the transient state when the load
angle is in the out-of-stability zone through controling the
rotor-excitation and increasing the generator’s electric motive
force.This lead to increase the generator’s maximum power
and to increase the generator’s stability-torque which lead to
return the synchronous generator to synchronous-steadystate
without need of discconecting it from network.Then put
the mathmatical model.
Objective: To compare the effects of restrictive versus maintenance fluid in the
management of transient tachypnea of the newborn on respiratory support and
hospitalization duration .
Methods: The study sample included 68 full term neonates diagno
sed with transient
tachypnea of the newborn(TTN) in Neonatal Intensive Care Unit at Tishreen University
Hospital in Lattakia during (2016 - 2017) Patients were randomized into two groups:
1_A group of 33 patients received restricted fluid management of 40ml/kg /day on
the first day of life increased by 15ml/kg/day for all patients until 150ml/kg/day.
2_A group of 35 patients received standard fluid management of 60ml/kg /day on the
first day of life increased as mentioned earlier.
The two groups were assessed daily for indicators of dehydration including:(weight,
urine output, electrolytes ,blood urea nitrogen, creatinine , glucose and urine specific
gravity)blood oxygen saturation was monitored by arterial blood gas and pulse oximeter
and respiratory
This study includes an experimental work to determine the effect of ultraviolet radiation (uv-rays) on the mechanical behavior of the conveyor rubber vulcanizing, which used in various transport operations, and in the cement plant Tartus. In this wor
k, it has been prepared different samples of belts, and they were exposed to uv radiation at differente times, then they were tested to know its wear and tensile strength.
The results were compared with samples similar to the samples tested, which was not exposed to the rays of UV, and with other samples exposed to temperatures, and that in order to reach the ideal conditions for the use of these belts, which ensures longer period of use and safe conditions. This study showed that uv-rays increase the average of wear and the tensile strength of belts.
Poultry litter is an organic waste in Syria which can be a source of clean
energy if treated anaerobically. This research aimed to investigate the effect of
mechanical pretreatment of poultry litter in producing biogas and methane.
Experiments wer
