This study included a test of 90 chickens; 90 samples as (a chest) and 90 samples as (a thigh). These samples were divided into four categories: the first one (45 chests) was stored with packages in a tin sheet, the second (45 chests) unpacked, the third (45 thighs) was stored with packages in a tin plate, the fourth (45 thighs) unpacked. The samples of each category were divided into three groups. Each group consists of 15 samples. These groups were stored at (25+°, 4+°, 20-°) .Then, the pH and the total count of bacteria were measured during storage in order to observe the time in which the samples will start to spoil in accordance with the Syrian Standards and Specifications Corporation 2007. We noticed the following physical changes: color, odor, flavor and texture. The results showed that the spoilage of the thigh samples happened before the chest ones and the packaged samples before the unpackaged ones. The samples spoiled after 24h of storage at 25+° and after 7 days of storage at 4+°, whereas, there was no spoilage noticed for the samples at 20-° but the appearance changed after 6 months of storage. Packing had a good effect on preservation. The conclusions and the suggestions were written in order to guide the consumer in the field of poultry meat storage.

Research summary
تتناول هذه الدراسة تأثير درجات الحرارة المختلفة على فترات حفظ لحوم الدواجن، سواء مع التغليف أو بدونه. تم اختبار 90 عينة من صدور وأفخاذ الدجاج، وقسمت العينات إلى أربع فئات: صدور مغلفة وغير مغلفة، وأفخاذ مغلفة وغير مغلفة. تم تخزين العينات في ثلاث درجات حرارة: +25 مئوية، +4 مئوية، و-20 مئوية. تم قياس درجة الحموضة (pH) والتعداد الجرثومي لتحديد وقت بدء فساد العينات. أظهرت النتائج أن العينات المغلفة تفسد أسرع من غير المغلفة عند درجات الحرارة +25 مئوية و+4 مئوية، بينما لم يلاحظ فساد عند درجة -20 مئوية، ولكن تغير المظهر بعد 6 أشهر. خلصت الدراسة إلى أن التغليف له تأثير إيجابي عند التجميد وسلبي عند التبريد، وأوصت بضرورة توعية المستهلكين حول أفضل طرق حفظ لحوم الدواجن.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال حفظ اللحوم وتقديم توصيات للمستهلكين. ومع ذلك، يمكن تحسين الدراسة من خلال تضمين أنواع أخرى من اللحوم لمقارنة النتائج. كما أن الدراسة تركز بشكل كبير على الجانب الجرثومي والحسي، وكان من الممكن تضمين اختبارات كيميائية أخرى لتقديم صورة أشمل. بالإضافة إلى ذلك، يمكن تحسين تصميم الدراسة من خلال زيادة عدد العينات وتنوع مصادرها لضمان تمثيل أوسع للنتائج.
Questions related to the research
  1. ما هي أفضل درجة حرارة لحفظ لحوم الدواجن وفقًا للدراسة؟

    أفضل درجة حرارة لحفظ لحوم الدواجن هي -20 مئوية.

  2. ما هو تأثير التغليف على حفظ لحوم الدواجن عند درجة حرارة +4 مئوية؟

    التغليف له تأثير سلبي على حفظ لحوم الدواجن عند درجة حرارة +4 مئوية، حيث يزيد من نمو الجراثيم.

  3. كم من الوقت يمكن حفظ لحوم الدواجن عند درجة حرارة +25 مئوية قبل أن تبدأ في الفساد؟

    يمكن حفظ لحوم الدواجن عند درجة حرارة +25 مئوية لمدة 24 ساعة قبل أن تبدأ في الفساد.

  4. ما هي التوصيات الرئيسية التي قدمتها الدراسة للمستهلكين؟

    أوصت الدراسة بتوعية المستهلكين حول كيفية حفظ لحوم الدواجن بالشكل المثالي، وتجنب إعادة تجميد اللحوم بعد ذوبانها.

The research aims to study the possibility of lengthening Remember chicken meat, chilled by his treatment extracts the oily plant cardamom, cinnamon, Zingiber and also curb the role of the pseudomonas bacteria in chicken meat spoilage through conservation radiator with anti impact during the oily extracts.
The aim of this investigation is to preserve fresh Awassi lamb meat at different storage conditions. The Awassi lamb from the thigh part of fresh meat was stored in Vacuuming Polyethylene Packaged with 100% CO2, 100% N2 and 100% vacuuming and at temperature +3 ºC and +7 ºC. The study showed that the meat can be stored at temperature +3ºC between 20 -30 days for the CO2 and vacuuming, and between 10-20 days for the N2 . The study also indicated that the meat can be stored at temperature +7 ºC between 10-20 days for CO2, and for 10 days under N2, and up to 10 days for the vacuuming without altering the organoleptic properties.
Compacting hot mixes asphalt (HMA) at low temperatures or mixing it in the asphalt at high temperatures is a constant source of concern to researchers, as compacting and mixing at non-ideal temperatures leads to adverse results, which negatively affect the properties of asphalt concrete and lead to problems paving.
Some biological parameters of the parasitoid, Encyrtus aurantii (Geoffroy) (Hymenoptera : Encyrtidae) were studied under controlled laboratory conditions at five levels of temperature 18, 21, 24, 27, and 30 °C, 65±5% R.H. and a photoperiod of 16:8 (L:D) h when reared on Brown soft scale Coccus hesperidum L. (Homoptera: Coccidae) reared on Pumpkin Cucurbita moschata during the season 2010- 2011 . Result showed that the longer developmental period from egg to pupa was on 18 °C with an average of 24.25 days, and the lower developmental period was on 30°C with an average of 8.25 days. The longer developmental period from pupa to adult was on 18 °C with an average of 10.75 days, and the lower period was on 30 °C with an average of 5.5 days. The lower developmental threshold (LDT) from egg to pupa was 15.83°C, and 14.34°C from pupa to adult. E. aurantii required a Sum of Effective Temperatures (SET) of 122.74 degree-days above the lower developmental threshold (16.95 °C) to complete the development from egg to adult.
This work is assigned to study the influence of different interaction potential forms on the pressure and internal energy of crystalline argon along its isothermal curves at high temperatures, expanded from melting point temperature up to room temp erature at different molar volume values expanded up to its value, corresponded experimental equilibrium curves with gaseous and liquid phases within the framework of quasi-classical approximation. The pair-wise inter-atomic forces in conjunction with three-body forces were taken into consideration. The results of this study regarding the pressure and internal energy of crystalline Argon were compared with available experimental data. The comparison clearly indicates that the calculated results coincide well with the experimental results.
