درس في هذا البحث تثبيط تآكل حديد الترانسمسيون Transmission في محلول (MHCl 1) بوجود حمض السكسينيك في درجات الحرارة ( 20-30-40-50-60 ) درجة س عند تراكيز ضمن المجال (10-6- 10-4) M لمدة ساعتين باستخدام طريقة الانخفاض في الوزن .
The corrosion inhibition of transmision steel in 1M HCl solution in the presence of Succinic acid at temperature (20,30,40,50,60)°C at concentration between (10-6- 10-4) M for two hours were studied using weight loss method.

Research summary
تتناول هذه الدراسة تأثير حمض السكسينيك كمثبط لتآكل حديد الترانسمسيون في وسط حمضي من حمض كلور الماء (HCl) بتركيز 1M. أجريت التجارب عند درجات حرارة مختلفة (20، 30، 40، 50، 60) درجة مئوية وتراكيز مختلفة من المثبط (10^-6 إلى 10^-4 M) لمدة ساعتين باستخدام طريقة الانخفاض في الوزن. أظهرت النتائج أن كفاءة التثبيط تزداد بزيادة تركيز المثبط ودرجة الحرارة، حيث بلغت الكفاءة العظمى حوالي 97% عند درجة حرارة 60℃ وتركيز 10^-4 M. تم حساب معلمات التنشيط مثل طاقة التنشيط (Ea) والأنتالبية (ΔH) والأنتروبية (ΔS) ووجد أن الامتزاز يتبع قانون لانغميور. كما أشارت النتائج إلى أن الامتزاز فيزيائي وليس كيميائيًا.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال حماية المعادن من التآكل، خاصة في البيئات الحمضية التي تتسبب في تآكل الحديد بشكل كبير. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين تجارب إضافية باستخدام مثبطات أخرى للمقارنة وتحديد فعالية حمض السكسينيك بشكل أكثر دقة. ثانيًا، لم يتم التطرق إلى تأثير العوامل البيئية الأخرى مثل الرطوبة والضغط، والتي يمكن أن تؤثر على كفاءة التثبيط. أخيرًا، كان من الممكن توسيع الدراسة لتشمل تطبيقات عملية في الصناعات المختلفة لتأكيد النتائج المخبرية.

The corrosion inhibition of transmision steel in 1M HCl solution in
the presence of Vanillin at temperature (20,30,40,50,60)°C at
concentration between (100-500) ppm for two hours were studied
using weight loss method.
The aim of this work is to study the effect of the aging heat treatment on the pitting corrosion resistance of martensitic stainless steel. In this research a number of specimens from martensitic stainless steel were subjected to solution treatment a
t 1050 for one hour followed by water quenching then aging in the temperatures range (400-750) for different holding times (1-16 hrs).
After heat treatment, two types of corrosion tests (accelerated test and immersion test) were conducted. The results obtained in this research showed that the pitting corrosion resistance was
affected by Aging temperature and three critical temperatures were found in corrosion test: the
specimens aged at 475 0C had maximum corrosion rate. This may be due to the presence of stringer δ-
ferrite and precipitation of very fine precipitates which precipitated heterogeneously in the martensitic
matrix, which led to an increase in corrosion rate. The specimens aged at temperatures range (550 – 625) 0C had minimum values of corrosion rate, this is attributed to the high volume fraction of retained austenite. The specimens aged at temperatures above 625 had intermediate corrosion rate.
The type of pits, which resulted from two pitting corrosion tests, was independent form the form of δ-ferrite and carbides which presence in microstructure.
The investigation was carried out during 2011-2012 at the laboratories of Plant
Protection Dep., Faculty of Agriculture, and Chemistry Dep., Damascus
University. The fatty acid composition in the seed and flower of Chinaberry
(Melia azedaracht L.)
was studied by Gas Chromatography. Results showed
that four fatty acids with different rate in seed and flowers of Chinaberry. The
ratio of unsaturated fatty acid was highly in dry and fresh seed oil and reached
88.66% and 85.43%, respectively. Where the percentage of linoleic acid was
higher than oleic acid. The percentage of saturated fatty acids was highly in oil
flowers (39.97%), where the ratio of stearic acid was the highest followed by
palmitic acid. Tthe efficacy of oil extract of dry, fresh seed and flowers
Chinaberry for suppressing the growth of the fungi, Penicillium digitatum and
Botrytis cinerea on artificial media in comparison with standard fungicides,
benomyl and procymidone under laboratory condition was also evaluated.
We studying in this research the reaction with Zinc sulphate in an
aqueous solution by physical - chemical method in presence of
Succinic Acid , and determined compounds which are formed in
this solution and we calculated of it formation the const
ants.
After we used these electrolytes in plating by Zinc , that is by
electro precipitation of this metal on the solid electrodes (steel,
copper) so that we definite the best of these electrolytes for galvany
and the set necessary conditions for its use.
This research aims to study the reduction of air heaters corrosion in
steam boilers and increasing their efficiency , by the application of
combined heating of air by steam and exhaust gases.
The experimental data of this research demonstrates tha
theater
corrosion could bereduced by maintaining the exhaust gases
temperature above the dew point of sulfuric acid depending onthe
amount of sulphur in the fuel oil ,by controlling air heat temperature
by steam.Which increases the boiler efficiency as a consequence of
reducing the fuel consumption by 9% as a maximum , reduces heat
loss, minimizes maintenance costs and reduces the time of emergency
shutdowns.
