In this research study of the conditions necessary for the preparation of a chemical compound hydroxyapatite HA [HA: Ca10 (PO4) 6 (OH) 2] Depending on normal vital source ( eggshell ) , which contains a large amount of calcium carbonate , which will be dealt with Acetic acid for acetate calcium Ca (CH3COO)2 , which in turn will be dealt with disodium hydrogen phosphate Na2HPO4, where and to prepare the treatment process depends on several factors , including: the concentration of the solutions , Solution temperature, stirring speed and addition , the degree of purity of the material used and its source, and the pH of the solution PH . The study showed that the chemical formula of the compound outlined in the bunting record is: Ca10 (PO4) 6 (OH) 2 and has a Molar ratio Ca / P stood at 1.65344 and preparation process was the best in the burned model of the form , dried and this was confirmed by sampling study of the two models , dried and burned in IR spectroscopy and spectroscopy x-ray diffraction XRD where the burned model output was crystalline either in the form of dried product was mixed crystalline and crystalline .


Artificial intelligence review:
Research summary
تناولت هذه الدراسة تحضير مركب هيدروكسي أباتيت (HA) باستخدام قشر بيض الدجاج كمصدر طبيعي لكربونات الكالسيوم. تم تحويل كربونات الكالسيوم إلى خلات الكالسيوم باستخدام حمض الخل، ثم تم معالجة خلات الكالسيوم بفوسفات ثنائي الصوديوم الهيدروجينية للحصول على هيدروكسي أباتيت. تم دراسة تأثير عدة عوامل على عملية التحضير مثل تركيز المحاليل، درجة حرارة المحاليل، سرعة التحريك، ودرجة حموضة المحلول. أظهرت النتائج أن المركب المحضر يمتلك صيغة كيميائية Ca10(PO4)6(OH)2 بنسبة مولية Ca/P تساوي 1.65344. كما أظهرت الدراسة أن النموذج المحروق كان أكثر بلورية من النموذج المجفف، وهو ما تم تأكيده باستخدام مطيافية الأشعة تحت الحمراء وانعراج الأشعة السينية. تعتبر هذه الدراسة ذات أهمية بيئية واقتصادية، حيث تساهم في التخلص من نفايات قشر البيض وتوفير مادة هيدروكسي أباتيت للاستخدامات الطبية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة هامة في استغلال الموارد الطبيعية المتاحة بطريقة فعالة واقتصادية. ومع ذلك، كان من الممكن تعزيز الدراسة بإجراء تجارب إضافية للتحقق من خصائص المركب المحضر في التطبيقات العملية مثل جراحة العظام والأسنان. كما أن الدراسة لم تتطرق بشكل كافٍ إلى مقارنة أداء المركب المحضر مع المركبات التجارية المتاحة في السوق. بالإضافة إلى ذلك، كان من الممكن تحسين الوضوح في بعض الأجزاء التجريبية وتقديم المزيد من التفاصيل حول الإجراءات المستخدمة.

The aim of this research is to study the optimal conditions for the preparation of hydroxyapatite , Chemical formula: Ca10(PO4)6(OH)2 (HA). In the three-component system: Ca(NO3)2-(NH4)2HPO4-NH3.H2O , Calcium Nitrate was prepared based on the calc ification of the white eggshell . to obtain calcium oxide (CaO), which is treated with nitrogen acid, while ammonium phosphate Mono hydrogen and ammonium solution was taken from its pure packaging. Hydroxyapatite (HA) Ca10 (PO4) 6 (OH)2was prepared under specific conditions, mainly: concentration of solutions used, speed of addition of reagents, reaction mix temperature, rotational speed, purity of materials used, and pH of the solution. The study showed that the solid compound recorded in the three-component system, which was separated from the liquid phase and dried and chemically analyzed, has the total chemical formula Ca10 (PO4) 6 (OH)2 and has a Molar ratio of Ca / P= 1.666 . and the preparation process was better in the model burned from the dried model and confirmed by the study of samples of the models dried and burned by IR infrared spectroscopy and XRD X ray diffraction spectroscopy, The burner model was a crystalline product, but in the dried model the output was mixed crystalline and not crystalline.
Thousand years ago, Beans was known commonly as legumes or pulses. And used to have an important role in agriculture production and daily food for most of the world population. The chemical compositions of plant have been studied. Comparing with soybeans and peanuts, the general chemical analysis showed increase in sugar and protein rates, while the lipid rate was so low.
This research was conducted to apply the technique of Artificial Insemination in poultry for the first time in the Syrian Arab Republic , and study the differences between the impact of the use of fresh or stored semen on the fertilization rate in hatching eggs . Results showed that the response to massage was different between cocks, It was greater in the cock A and cock B while the cock C was the least response to massage. The greater volume of ejaculate was obtained from the cock A( 0.072) ml ,and the least volume of ejaculate was obtained from the cock B (0.05) ml . The volume of ejaculate obtained from the three cocks was ranged between (0.049 -0.072) ml. The value of X in the count ranged between (230 - 237) sperm, semen concentration ranged between (4.6 - 4.7) billion sperm / ml. It also found that Insemination with a fresh semen injection yielded fertilization rate (91%), While insemination with semen injection cooling at the heat +4 ̊ C for 48 hours yielded fertilization rate (67%) .
In this research, the total content of phenols and flavonoids was determined from the peels of some Syrian citrus fruits and the total antioxidant activity of them was studied, and the effect of changing the extraction method on this activity and content was studied.
In this study, the effect of temperature on volume strains in three types of local clay soils was studied after adding different percentages of sand for each soil (10%-20%-30%40%-50%) when temperatures change from (20-60)° C to be used as liners i n solid waste landfill sites . The results of the study showed that the mixing of sand with the clay played a key role in reducing the magnitude of volume strains between (24-27%) of the value of strains.
