Analysis of relations and forces of production in extraction And pearl industry in the Arabian Gulf 1900-1950 *
...Show More Authors

بسبب محدودية الموارد الطبيعية، فأن سكان الخليج ومنذ القدم وجهوا جلّ نشاطاتهم توجهاً بحرياً: صيد الاسماك وصناعة اللؤلؤ العنصر الرئيس في حجم التشغيل، وتكوين الفائض الاقتصادي في المنطقة آنذاك.

لقد تزايدت أهمية هذا النشاط بخاصة بعد النصف الثاني من القرن التاسع عشر، لرواج تجارة اللؤلؤ عالمياً، وأنفتاح الخليج على الدول الاوروبية التي شهدت نهضة صناعية متسارعة، وحيث وصلت الخليج العديد من بضائعها ذات الاسعار المناسبة والنوعية الافضل.

إن عدد العاملين في صناعتهِ لم يقل عن 20-25% من مجموع العاملين في المنطقة خلال الربع الاول من القرن العشرين ويبين لنا المؤرخ J.G.Lorimer إن عدد العاملين وصل الى حوالي 90 ألف شخص من سكان قدر مجموعه بـ 300 ألف نسمة وذلك في أواسط العقد الأول من القرن العشرين. وبالأضافة الى العمل المحلي هناك وافدون من أيران والهند وباكستان مع وافدين من شرق أفريقيا، أستُقدم العديد منهم كعبيد سخرهم مالكوهم للعمل في صناعة اللؤلؤ وذلك بالرغم من محاربة السلطات البريطانية آنذاك لأعمال القرصنة وتجارة العبيد في منطقة الخليج والمحيط الهندي.

تفصح التراتيب الوظيفية في صناعة اللؤلؤ عن وجود تسع فئات مُقسمة بدقة حسب نوع العمل الذي تقوم به كل فئة. والعنصران الفاعلان في العملية الانتاجية هما:-

التاجر "الممول": يُمول العاملين بسلف تصل فائدتها الى حوالي 25% على أساس الموسم الذي يستمر بين 4-5 أشهر. وغالباً ما يستحوذ على الجزء الاعظم من الارباح بطريقة أو بأخرى..

الغواص ومساعده: يُلاحظ هنا تناقضٌ واضح، فمن ناحية هما الحلقة الاهم والاخطر في العملية الانتاجية وحيث لا يملك الغواص الا قابلياته البدنية أثناء عملية الغوص؛ ومن ناحية أخرى هما من أكثر المتضررين مادياً وأجتماعياً وصحياً بين الاطراف الاجتماعية المشاركة في هذه الصناعة.

لم تعرف هذه المهنة نظاماً للأجور، بل كانت تعمل وفق طريقة "المحاصصة" ونادراً ما كان يحصل الغواصون ومساعدوهم على ما يسدون به سلفهم وديونهم السابقة مع فوائدها المتزايدة.

    النقطة المركزية: ان العاملين عادةً ما يبقون في دين مستديم، وهذا ما يخوّل الممول حسب العرف السائد آنذاك والذي هو بمثابة قانون مُلزم من الابقاء عليهم للعمل في المواسم اللاحقة.

    لقد تراجعت صناعة اللؤلؤ منذ أوائل ثلاثينيات القرن الماضي، أثر اجتياح اللؤلؤ" الرخيص" المستزرع في اليابان ومناطق أخرى من العالم. ومن حسن حظ المنطقة ان صادف ذلك البدايات الاولى للأكتشافات النفطية حيث انتقل العديد من العاملين فيها الى الصناعة النفطية الحديثة.

The Economic Impacts of Using Renewable Energy Technologies for Irrigation Water Pumping and Nanoparticle Fertilizers on Agri-Food Production in Iraq
...Show More Authors

While traditional energy sources such as oil, coal, and natural gas drive economic growth, they also seriously affect people’s health and the environment. Renewable energies (RE) are presently seen as an efficient choice for attaining long-term sustainability in development. They provide an adequate response to climate change and supply sufficient electricity. The current situation in Iraq results from a decades-long scarcity of reliable electricity, which has impacted various industries, including agriculture. There are diverse prospects for using renewable energy sources to address the present power crisis. The economic and environmental impacts of renewable energy systems were investigated in this study by using the solar pumpi

Evaluation the efficiency of different techniques for extraction and purification of Tomato yellow leaf curl virus (TYLCV)
...Show More Authors

This study was conducted to evaluate the efficacy of different techniques for extraction and purification of Tomato yellow leaf curl virus (TYLCV). An isolate of the virus free of possible contamination with other viruses infecting the same host and transmitted by the same vector Bemisia tabaci Genn. was obtained. This was realized by indicator plants and incubation period in the vector. Results obtained revealed that the virus infect Nicotiana glutinosa without visible symptoms, while Nicotiana tabaccum var. White Burley was not susceptible to the virus. The incubation period of the virus in the vector was found to be 21 hrs. These results indicate that the virus is TYLCV. Results showed that Butanol was more effective in clarification the

Possibility of glucose level assessment using the blood of gingival probing and dental socket after tooth extraction
...Show More Authors

Background: The association between diabetes and inflammatory dental diseases had been studied extensively for more than 50 years. A large evidence base suggests that diabetes is associated with an increased prevalence, extent and severity of gingivitis and periodontitis and loss of teeth. Many patients do not aware that they are diabetic.Objectives:The aim of the current study was to assess a fast, non-invasive, safe procedure to screen for diabetes and its severity in dental clinics and to assess the change in blood glucose level before and after tooth extraction during periodontalResults: there were no significant differences between the blood samples collected before tooth extraction from finger puncture method (FPB) and the gingival

Abstract<p>A total of four types of instant dry yeast <italic>Saccharomyces cerevisiae</italic> which are Gloripan, Swan, Super Man (China) and Saf (Turkey), were obtained from the local market in Baghdad, Iraq. All the types were identified according to their morphological characteristics and screened for their ability to produce biosurfactant by oil spread method. Biosurfactant was extracted and partially purified by precipitation with ammonium sulfate at saturation ratio75%. Antibacterial activity of crude and partially purified biosurfactant was tested against twenty isolates of <italic>Pseudomonas aeruginosa</italic> and the results showed that crude biosurfactant has no</p> ...

Production and Evaluation of Biodiesel from Sheep Fats Waste
...Show More Authors

Animal fats are a good, promising and ethical alternative source for biodiesel production, but they need more complex treatments than vegetable oils. Iraqi butchery plants waste fats (sheep fat) which are suggested as feedstock to produce biodiesel. This type of fat contains a large quantity of free fatty acids (FFAs) (acid number 49.13 mg KOH/g of fat). The direct transesterification of such fats produce high amount of soap instead of desired biodiesel, so a pre-treatment step (to reduce FFAs) is necessary before transesterification. This step was done by esterification of the free fatty acids in the fat by adding ethanol and using 1% acid catalyst (H2SO4) for 30 minutes. The results showed that the acid number of sheep fat after pre-tr

Preparation and Characterization of Nay Zeolite for Biodiesel Production
...Show More Authors

Iraqi kaolin was used for the preparation and characterization of NaY zeolite for biodiesel production via esterification reaction. Oleic acid was used usually as a typical simulated feedstock of high acid number for the esterification reaction.

   The chemical composition for the prepared Nay zeolite is as following:  (Ca2.6Na1.K0.1)(Al6.3Si17.7)O48.16H2O, the silica to alumina ratio in the prepared catalyst was found equal to 2.6 and Na2O content was 12.26 wt. %, with relative crystallinity equal to 147.4 % obtained by the X-ray diffraction. The surface area result shows that the prepared catalyst has 330 m2

Two field experiments were conducted during the spring season 2020 in Karbala governorate to study the effect of irrigation systems, irrigation intervals, biofertilizers and polymers on some characteristics of vegetative growth and potato production. The results showed that there were significant differences in the values of the average plant height due to the effect of the double interference between the irrigation system and the improvers, The height of potato plant under any irrigation system was superior when adding conditioners compared to the control treatment, as it reached 48.56, 58.00 and 64.33cm when adding polymer, biofertilizer, and polymers+ biofertilizers, respectively compared with the control treatment of 44.64cm in the surf

Plasma Production and Applications: A Review
...Show More Authors

Large amounts of plasma, the universe’s fourth most common kind of stuff, may be found across our galaxy and other galaxies. There are four types of matter in the cosmos, and plasma is the most common. By heating the compressed air or inert gases to create negatively and positively charged particles known as ions, electrically neutral particles in their natural state are formed. Many scientists are currently focusing their efforts on the development of artificial plasma and the possible advantages it may have for humankind in the near future. In the literature, there is a scarcity of information regarding plasma applications. It’s the goal of this page to describe particular methods for creating and using plasma, which may be us
