Abstract

Alkaloids often had pharmacological effects. The aim at this study is to increase some alkaloids in fenugreek. Callus induction occurred on cotyledon segments 5 mm long. Murshige and Skoog medium (MS) supplied with 1 mg.lˉ¹ of 2, 4 – D and 0.4 mg.lˉ¹ of kinetin was prepared. The best medium maintained callus was using MS medium supplied with 0.5 mg.lˉ¹ 2, 4-D and 0.5 mg.lˉ¹ kinetin. Callus formation was allowed to take place for a period of thirty days in the dark at 25°C±2. Calli were analyzed using high performance liquid chromatography (HPLC).Methanol callus extract showed high concentrations of some alkaloids compared to the methanol extract of cotyledons. For increasing, the concentration of secondary metabolites, NaCl was added at concentrations 0, 1, 1.5 or 2 g.lˉ¹, sorbitol at concentrations 0, 7, 8 or 9 g.lˉ¹. NaCl at 2 g.lˉ¹ led to significant increase in trigonelline reaching 1354.72 µg per 100 mg fresh weight of callus. NaCl at 1g.lˉ¹ increased choline and carpaine reached 400.82, 483.92 µg.mlˉ¹ per 100 mg respectively. Treatment with 9 g.lˉ¹ sorbitol increased trigonelline and carpaine reached 1666.41, 742.67 µg per 100 mg respectively, while treatment 8 g.lˉ¹ sorbitol significantly increased in choline recorded 588.87 µg per 100 mg.

Abstract

To investigate the effect of NaCl or pH levels on the survival of Culex sp. larvae , a sample of these larvae was collected from some pools in Basrah city and exposed to 5,10,15 and 20 ppt of NaCl or 2,3 and 4 pH levels . Lethal concentration for 50% of the exposed larvae (LC50) in NaCl and pH treatments were 6.2892 ppt and pH 2.98, respectively .All of the larvae died at the first few hours of exposure to either 20 ppt of NaCl or pH =2 . The results of this study suggest that NaCl levels higher than 6.289 ppt and pH levels higher than 2.98 ( in Culex sp. larvae environment ) are very effective on the larvae survival, thus these levels could be used in mosquitoes control efforts.

لدراسة تأثير مستويات ملح NaCl او دالة الحموضة pH في بقاء يرقات بعوض Culex sp.، تم جمع عينة من هذه اليرقات من بعض برك مدينة البصرة وعرضت الى تركيز 15،10،5او 20 ppt منNaCl او 3،2 او 4 pH ، وجد ان التركيز القاتل لنصف اليرقات (LC50) في معاملات NaCl و pH كان ppt 6.2892و 2.98 pH على التوالي. ماتت اليرقات في الساعات القليلة الاولى من التعرض ل20 ppt من NaCl او pH= 2. تقترح نتائج هذه الدراسة ان مستويات NaCl الأعلى من ppt 6.2892 ومستويات pH الأعلى من 2.98 مؤثرة جدا في بقاء يرقات Culex sp. ، وعليه فأنها يمكن ان تكون مفيدة في جهود مكافحة البعوض.

Abstract

The electrical conductivity (E.C.) changes of a certain concentration (1000ppm) of aqueous sodium chloride and calcium chloride dihydrate solutions as a function to the solubility with and without applying a multiple constant magnetic field at different temperature and pH values were studied. A magnetic funnel with a magnetic field power of 450 gauss was used to prepare the magnetic water by passing the later 1, 5 and 10 times with flow rate of 41.66 mL/sec, before dissolving the sodium chloride and calcium chloride dihydrate salts. There was a proportional relationship between the solubility of sodium chloride and calcium chloride dihydrate and the number of water exposure to the magnetic field. There was also a proportional relationship between the electrical conductivity records and the increasing in temperature and pH values. It was found that the increasing in pH value is more effective as compared with the elevation in temperature degree. In general, the magnetic solutions of sodium chloride and calcium chloride dihydrate showed highly electrical conductivity values as compared with non-magnetic solutions. It was clear, that the advantages from using magnetized solutions of these two salts will be useful in the biological and physiological systems.

Abstract

In this work, the effect of sodium chloride (NaCl) powder addition with different amounts on microstructure and mechanical properties of Al-12 wt. %Si alloy was investigated. In this technique, modification by NaCl was used because of its availability and low price comparing to other modifiers such as Sr and Sb. A 1000 °C as pouring temperature of molten alloy was used. The present results showed that there is a significant change in the mechanical properties and microstructure compared with unmodified alloy. The optimum properties were found by adding 0.5wt% NaCl to the alloy, and also the modification of microstructure alloy. Mechanical properties and microstructure of Al-12wt. %Si alloys that poured from 1000 °C with NaCl additives were compared with the corresponding alloys but at 800 °C pouring temperature, it is found that alloys poured from 1000 °C have best properties as compared with the same alloys poured from 800 °C.

في هذا البحث تم دراسة تأثير إضافة كميات مختلفة من مسحوق كلوريد الصوديوم (NaCl) على البنية المجهرية والخواص الميكانيكية لسبيكة Al-12wt.%Si. في هذه الطريقة تم اجراء عملية التحوير بواسطة كلوريد الصوديوم وذلك لوفرته ولرخص ثمنه بالمقارنة مع المحورات الاخرى مثل السترونشيوم و الانتيمون. استخدمت درجة حرارة 1000 درجة مئوية لعملية الصهر وصب المنصهر من هذه الدرجة وذلك بسبب حدوث ذوبان المادة المضافة الى المنصهر والتي يعتقد ان الكلور سوف يتطاير كغاز تاركاً الصوديوم في السبيكة المذابة ليؤدي عمله. اظهرت النتائج المستحصلة بان هنالك تغييراً في الخواص الميكانيكية والبنية المجهرية بالمقارنة مع السبيكة غيرالمحورة. تم تحديد الاضافة التي تعطي خواص اعلى والتي كانت عند اضافة نسبة 0.5% من كلوريد الصوديوم الى السبيكة وكذلك تحوير البنية المجهرية. تم مقارنة الخواص الميكانيكية والبنية المجهرية لسبائك Al-12wt.%Si المصوبة من درجة حرارة 1000 درجة مئوية والمضافة اليها كلوريد الصوديوم بنفس السبيكة ولكن بدرجة حرارة صب مقدارها800 درجة مئوية, حيث وجد ان صب السبائك من درجة حرارة 1000 درجة مئوية تعطي خواص افضل من صب السبائك نفسها من درجة حرارة 800 درجة مئوية.
