Nursery ward is the safe place for premature after deliverey . It contains the basic requirements of life to him. but full of noise caused by alarms of devices, conversations of health team, ringing phones, and close the doors, exceeds what is recommended by the American Academy of Pediatrics in the Nursery wards 45 dBA (decibel A-weighting). Although it stimulates the autonomic system leading to physiologic instability like disorder in the level of oxygenation. We found in this study conducted on 30 premature with pre and post test, that the level of noise within first hour of non interventions reached 67.2 dBA, level of oxygenation inversely with noise level in it, and reduction of noise level under 45 dBA at second hour increases the oxygenation significantly. so we suggests to make reduce noise interventions within daily practices of nursing procedures, and subsequent research to study effect of noise on the rest of vital premature indicators

Research summary
تناولت الدراسة تأثير خفض مستوى شدة الضجة على معدل الأكسجة لدى الأطفال الخدج في قسم الحواضن. أجريت الدراسة على 30 خديج باستخدام اختبار قبلي وبعدي. وجد الباحثون أن متوسط شدة الضجة خلال ساعة من المراقبة دون تدخل لخفض الضجة بلغ 67.2 ديسيبل، وأن خفض الضجة إلى ما دون 45 ديسيبل لمدة ساعة أدى إلى زيادة ملحوظة في معدل الأكسجة. تشير النتائج إلى أهمية إدراج إجراءات خفض الضجة ضمن الممارسات التمريضية اليومية، وإجراء أبحاث لاحقة لدراسة تأثير الضجة على باقي المؤشرات الحيوية للخديج. أوصت الدراسة بتقديم محاضرات تثقيفية ودورات تدريبية للطاقم الصحي حول أهمية خفض شدة الضجة على صحة الخديج.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة هامة في فهم تأثير الضجة على صحة الأطفال الخدج، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، حجم العينة صغير نسبياً (30 خديج)، مما قد يؤثر على تعميم النتائج. ثانياً، لم تتناول الدراسة تأثير الضجة على باقي المؤشرات الحيوية والسلوكية بشكل مفصل، وهو ما يمكن أن يكون موضوعاً لدراسات مستقبلية. ثالثاً، لم يتم توضيح كيفية قياس مستوى الضجة بدقة في بيئة الحواضن، مما قد يؤثر على دقة النتائج. على الرغم من هذه النقاط، فإن الدراسة تقدم إسهاماً مهماً في تحسين جودة الرعاية الصحية للأطفال الخدج.

Preterm birth is the leading cause of death for children under one year of age, and the main reason for the child to enter the incubator. Despite medical advances and technical winning in the care of premature infants., but they are exposed in Nurser y Ward for environment stimuli not compatible with their level of developmental and evolutionary such as high levels of light and the noise that exceed the recommended levels in Nursery Ward. This leads to stress reactions by premature immature systems. demonstrating in one of their faces instability in vital indicators especially heart rate and oxygenation which may submit him for a short or long-term injuries . Aim of the study: Determine the effect of reducing the level of light and noise intensity in environment of Nursery Ward on the heart rate and oxygenation for premature infants. Materials & Methods: This true experimental design study of before and after on a sample of 30 premature acceptable in the Nursery Ward in Albasel Hospital in Tartous. they were selected in simple random way. Data were collected using a list to record demographic and health information for the mother and premature. reads of light-meter and noise-meter sitting beside the premature incubator, and reads of Oxy-meter connected to the premature wrist. was taken to every 5 minutes in each phase of the four phases, 60 minutes for each one, and conducted in the same day.1) Non intervention phase. 2) reduce light Intensity without noise Intensity reduction phase.3) reduce noise Intensity without light Intensity reduction phase.4) reduce light and noise Intensity together phase. These data were collected and analyzed using appropriate statistical programs. Results: This study showed a significant decrease in the mean of heart rate and a significant increase in the mean of oxygenation in the last three phases, compared with means in the first phase. This reduction and increase in the means was larger significantly in the fourth stage compared with the second and third phases. That because reducing light and noise will reduce its physiological stress to premature thus lower the pulse rate and increasing oxygenation. We can thus reduce the use of light and noise measures to improve the care environment for premature.
Two experiments were couducted to study the effect of reducing the level of animal protein on the carcass quality of broilers. Eight hundred birds used in the first experiment were divided into ٤ groups and left under ٣ feeding stages. Four hundre d birds used in the second experiment were divided into two others groups and left under two feeding stages.
The research aims to take advantage of the solar energy, as a free energy, to run a water pump powered by solar energy, and to study the effect of the intensity of solar radiation on the performance of this pump in Syrian coast conditions. This resea rch has explained the necessary mechanism for determining the capacity of the pump and the electric PV panels required for the work of the pump and the area of these panels. Studying the effect of intensity of solar radiation on the performance of water pump through studying the impact of pump altitude and solar radiation intensity on water flow range at experiment location. It demonstrated that the flow of the pump is going through two phases with the increasing values of solar radiation during the day. It was found that the increasing value of the flow of the pump before the value of (520W/m2) of Solar radiation was greater than that after (520W/m2) and this led to the loss of a part of the solar energy falling during the day, especially on sunny days, and the value of the loss was about (27%) of the total amount of solar energy falling per day.
