جرثومة الزائفة الزنجارية كاشف فعال للتحري عن المستخلصات النباتية المثبطة لاستشعار النصاب
...Show More Authors

استشعار النصاب (Quorum sensing, QS) هو آلية معروفة تستخدمها جراثيم عديدة للسيطرة على عوامل الضراوة الهامة من خلال الإنتاج والاستجابة اللاحقة ل .)N-acylhomoserine (AHLs جرى تسجيل تثبيط استشعار النصاب (QSI) ، الذي يستهدف الإشارات المعتمدة على AHL، كاستراتيجية للسيطرة على الأمراضية الجرثومية. وبالتالي، تهدف هذه الدراسة إلى البحث عن قدرة جرثومة الزائفة الزنجارية كمؤشر للفحص السريع عن QSI المحتمل المتسبب عن المستخلصات النباتية على أساس تثبيط الصبغة. استخدمت أربع مستخلصات نباتية كحولية بضمنها: براعم زهور القرنفل المجففة ( Syzygium aromaticum L)، لحاء القرفة (Cinnamomum cassia L)، أوراق المورينجا (Moringa oleifera Lam)، والقطب (Tribulus terrestris L) وجرى مقارنة قابيلتها على التثبيط QSI)) مع الفيورانون. استخدمت طريقة الانتشار في حفر الهلام، إذ جري تلقيح عزلة الزائفة الزنجارية على وسط الهلام الخاص بـها الذي احتوى على حفر بحجم 8 ملم لتحميل تراكيز مختلفة من المستخلصات النباتية فضلا عن الفيورانون أو محلول الفوسفات الداريء (سيطرة سالبة). أظهرت النتائج نجاح الفيورانون في تثبيط صبغة البايوسيانين للزوائف الزنجارية دون التداخل مع النمو الجرثومي، وهذا يؤكد قدرة هذه العزلة الجرثومية كمؤشر فعال يستدل من خلاله على وجود QS. الأهم من ذلك، سبب مستخلص القرنفل بتراكيز مختلفة في تثبيط تام لصبغة البايوسيانين مع تأثير ضئيل على النمو الجرثومي. عند استخدام القرفة، أظهرت التراكيز العالية فقط تثبي ًطا واض ًحا لصبغة العزلة المستخدمة. تسببت المورينغا أي ًضا في درجة معينة من تثبيط الصبغة ولكن بتراكيز عالية فقط. وعلى العكس من ذلك، لم يؤثر القطب على إنتاج البيوسيانين ولا على الحيوية الجرثومية. يستنتج من هذه الدراسة نجاح عزلة الزائفة الزنجارية المنتجة للبايوسيانين في فحص مثبطات QS. توصي هذه الدراسة البسيطة باستخدام مثل هذه العزلة ككاشف عن QSI دون الاعتماد على استيراد سلالات معينة من جراثيم Chromobacterium violaceum أو Pseudomonas aureofaciens أو Agrobacterium tumefaciens.

An Experimental Study on the Effect of Shape and Location of Vortex Generators Ahead of a Heat Exchanger
...Show More Authors

An experimental study is carried out on the effect of vortex generators (Circular and square) on the flow and heat transfer at variable locations at (X = 0.5, 1.5, 2.5 cm) ahead of a heat exchanger with Reynolds number ranging from 62000< Re < 125000 and heat flux from 3000 ≤ q ≤ 8000 W/m2 .

In the experimental investigation, an apparatus is set up to measure the velocity and temperatures around the heat exchanger.                     

The results show that there is an effect for using vortex generators on heat transfer. Also, heat transfer depends on the shape and location. The circular is found t
