تمت دراسة القوى الممخلبة لبعض الحموض متعددة الكربوكسيل و أملاحها و مزائجها مع ثلاثي بولي فوسفات الصوديوم و بيروفوسفات الصوديوم بوجود حماضات الأمونيوم و كربونات الصوديوم، و لقد أبدت بعض المزائج قوة تمخلب تناغمية إيجابية؛ أي أن هذه المزائج أبدت قوة تمخلب أكبر من مجمـوع قـوة تمخلب مكوناتها الفردية في حين أبدت بعض المزائج قوة تمخلب سلبية، و لقد بلغ مقـدار تغيـر القـوة الممخلبة لثلاثي بولي فوسفات الصوديوم و حمض الليمون ما بين ثلاثة أضعاف إلى ثمانية و ثمانين ضعفاً عند تغيير بعض الشروط التجريبية. و يمكن الاستفادة من قوة التمخلب التناغمية الإيجابية في تعزيز دور المواد البناءة في المنظف، و من ثم تخفيض وزنه و من قوة التمخلب السلبية في إضـعاف قـوة تمخلـب مكونات المزيج و ترسيبها في الماء المعالج بشروط مثالية .
Mixtures of polycarboxylic acids and their salts with sodium tripolyphosphate and sodium pyrophosphate have been investigated in the presence of ammonium oxalate and sodium carbonate. Some of these mixtures demonstrated good chelating power synergy and some mixures inhibited the chelating power of the individual components from which the mixures composed of. The chelating power synergy of some mixtures can be used for enhancing the function of the builders and consequently decrease the weight of the detergent meanwhile the inhibition of the chelating power in the other mixtures can be used for precipitating their components in the treated water in optimum conditions. It is worth to mention that the chelating powers of sodium tripolyphsphate and citric acid increased as many as 3-88 times by changing some experimental conditions.

Research summary
تتناول هذه الورقة البحثية دراسة تأثير الأحماض الكربوكسيلية ومزيجها مع مواد البناء المستخدمة في مساحيق الغسيل. تم التحقيق في تآزر القوة المخلّبة لبعض هذه المزيجات في وجود أوكسالات الأمونيوم وكربونات الصوديوم. أظهرت بعض المزيجات قدرة مخلّبة جيدة، بينما قامت مزيجات أخرى بتثبيط القدرة المخلّبة للمكونات الفردية. يمكن استخدام تآزر القوة المخلّبة لبعض المزيجات لتعزيز وظيفة مواد البناء وتقليل وزن المنظف، في حين يمكن استخدام تثبيط القدرة المخلّبة لترسيب مكونات الماء المعالج في ظروف مثلى. تجدر الإشارة إلى أن القوة المخلّبة لثلاثي فوسفات الصوديوم وحمض الستريك زادت بمقدار 3-88 مرة عند تغيير بعض الظروف التجريبية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال تحسين فعالية مساحيق الغسيل وتقليل الأثر البيئي من خلال تقليل كمية المواد الكيميائية المستخدمة. ومع ذلك، يمكن انتقاد الدراسة لعدم تقديمها تفاصيل كافية حول الآليات الكيميائية الدقيقة التي تؤدي إلى تآزر أو تثبيط القوة المخلّبة. كما أن الدراسة قد استفادت من تقديم تحليلات أكثر شمولية حول تأثير هذه المزيجات على أنواع مختلفة من الأوساخ والملوثات. بالإضافة إلى ذلك، كان من الممكن أن تكون الدراسة أكثر فائدة إذا تم تضمين تجارب ميدانية لتأكيد النتائج المخبرية.

This research includes a study of the triple-sentence equilibrium curves consisting of electrolytic acid and apple acid in a binary mixture of water and (hexane, ethanol, tetrahydrofuran)
Some chemical, spectral and thermal characteristics of some humic acids
(HA) extracted from: Farm manure (Fm), biogas(Bio), compost (Com), forest
litters of pine (Pl) and of descendant forest (Dl), and their complexes with Camontmorillonite
were s
tudied by TGA and DTA analysis.
Phenolic compounds are known to be present in high concentration
in various of agro industrial wastes such as olive mill wastewater. As
they are highly biorecalcitrant a possible treatment by Advanced
Oxidation Processes has to be investigated.
T
he photocatalytic degradation of the phenolic acids p-Hydroxybenzoic
acid, Dihydroxybenzoic acid, gallic acid, vanillic acid, syringic acid) in the
presence of TiO2 deposit on a glass plate has been reported. A comparison for
the adsorption properties and the kinetics of reaction have been studied. The
kinetics were found to be first order for all compounds and were compared
with the compounds’ structures. The reaction rate for the compounds was
found as the order Di-HBA < GA < p-HBA ≈ SA ≈ VA.
The influence on the photdegradation rate of various parameters as pH, and
substrate’s concentration was studied for p-Hydroxybenzoic acid only. It was
found that the reaction is pH and substrate’s concentration dependence.
A removal efficiency (50-70%) was determined after 5hr using UVlamp
(15W- λ=360nm) and it increased up to 95% when H2O2 was
added.
The experiment was performed at Agricultural Research Center in Jousiyet
Al-Kharab in Al-Qsair district, Homs governorate during the 2010-2011 season
to investigate the effect of planting depth and organic acids on saffron growth
and productivity.
Four treatments including amino acids, amino Humic,
mixture of them in addition to the control were applied. Each treatment was
comprised of three planting depths (10, 15 and 20 cm). Results showed that by
increasing planting depth up to 20 cm a significant reduction had resulted in
the percentage of rooted plants and number of shoots while there were no
significant differences between the two depths 10 vs. 15 cm. The number of
leaves and their length were not affected significantly with the increasing of
planting depths. The number of flower, wet and dry weights of the stigmas
were increased significantly with the increase of planting depth from 10 to
15 cm. The application of the humic acids had significant superiority overall
the other applications in rooted plant percentage, number of shoots, number of
flowers and the dry and wet weights of the stigmas, while the application of the
mixture came in the second rank in number of flowers and the dry and wet
weights of the stigmas. However, no significant differences were occurred
between the control and application of amino acids. The highest percentage of
rooted plants was observed in applying humic acids in all depths and the
percentage of rooted plants reached 100%. The highest number of flowers,
highest stigmas wet and dry weights were observed with the interaction
between applying humic acids at 15 cm depth. The highest number of shoots
and number of leaves appeared with the interaction between 20 cm depth and
humic acids treatment, the longist leaves were appeared with the interaction
between amino acids and 15 cm depth.
Thirteen phenotypes of cultivated wild olive were selected during 2007- 2008
from four orchards in Mesiaf region, to study oil percentage and fatty acids
contents in these types for choosing types for oil production, in order to
propagate and cons
erve them in a germplasm, and then to be cultivated
because they have adapted to local climate in this region. The results were
analyzed statistically by using Gen-State program to calculate least significant
differences between values. The results confirmed the high biodiversity in these
studied types, and they were classified into five groups according to their oil
percentage and contents of oleic acid. The oil percentage ranged from 3.9 to
27.3 %, and the fatty acids had significant differences between them, the oleic
acid was in olive oil between 56.7 and 75.5%. The types P1-1 and p1-3 showed
the best results for producing oil.
