Ask ChatGPT about the research

This work aims to find approximate relationships to calculate the static durability of ball valve disc valves, based on material resistance and flexibility theory. Three groups were obtained, and these groups represent three mathematical charts, each of which corresponds to specific relationships obtained to calculate the stresses generated in the dish.

Research summary
تهدف هذه الدراسة إلى إيجاد علاقات تقريبية لحساب المتانة الستاتيكية للصمامات القرصية ذات الأطباق الكروية، وذلك بالاعتماد على مقاومة المواد ونظرية المرونة. تم الحصول على ثلاث مجموعات من المخططات الحسابية، كل منها يتوافق مع علاقات محددة لحساب الإجهادات المتولدة في الطبق. تركز الدراسة على تحسين فعالية الضواغط المكبسية من خلال تحسين الخواص الديناميكية والغازوديناميكية للصمامات. تم استخدام طرق حسابية مختلفة لتحديد الإجهادات في الصمامات تحت تأثير هبوط الضغط. توصلت الدراسة إلى أن الحسابات باستخدام طريقة العناصر المنتهية يمكن أن توفر نتائج أكثر دقة وشمولية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال تحسين فعالية الضواغط المكبسية، إلا أنها تفتقر إلى التطبيق العملي والتجريبي الذي يمكن أن يدعم النتائج النظرية. كما أن الاعتماد على العلاقات التقريبية قد يؤدي إلى بعض الانحرافات في النتائج الفعلية. يُفضل إجراء تجارب عملية لدعم النتائج النظرية وتقديم توصيات أكثر دقة وموثوقية.

This study describes the improvement of the reliability and effectiveness of the straight flow used in piston compressors, valves, and by modeling the flow of gas and the movement of plate valve. This model distributes the gas pressure and distorti ons plate valve as a flexible plate to be determined. This modeling test gas flow through the valve in the static measurements in addition to dynamic measurements of the end plate valve movement in the compressor has checksum where the comparison between numerical results and experimental results measured.
Translation is one of the oldest types of human activity, as it is a phenomenon inherent in human history from the oldest ages, as it appeared with the emergence of the need for a means of understanding between the peoples of the world due to the dif ference in the management of communication between them. Translation, like other fields of knowledge, was subject to the same rule of tradition mentioned earlier, so that when you look at the books of some Arab thinkers, you will find that the nature of their writings is of a foreign nature. Among the aims to be achieved in this research are: Introducing the theory of text types and their relationship to translation. Disclosure of the characteristics of this theory in translation. Clarify the importance of text types theory and its role in acquiring translation skills. Linguistic analysis of texts as a first station, followed by other consistent and harmonious stations that collectively work to achieve the communicative relationship of the various types of texts. Identifying the types of texts and then the types of translation approaches that work to reduce the gap between the source text and the access text.
Ship collision accidents are considered of the most serious incidents, due to the subsequent disastrous results both in terms of economic losses in ships and cargo, and the loss of human life as well as the great environmental pollution caused by i t. Therefore, continuous efforts are being made by research centers in order to understand the structural response of the hull as a result of these incidents and accurately analyzed. This research is interested in assessing the residual structural strength of a ship exposed to collision through the internal energy and the various structural stresses generated within it. The case is modeled for an oil tanker exposed to collision by the bulbous bow of another vessel moves at different speeds and different angles. The structural strength of the middle section of the struck ship was analyzed based on the numerical methods using Ansys Dynamic Explicit program. Which allowed the development of a clear vision for the structural changes and internal stresses energy with time during the collision process.
Influence of light represented by ultraviolet radiation having two different wavelengths, ٢٥٤ nm and ٤٠٠ nm, on some Iraqi cellulose extracted from reeds as a raw material has been studied. It was found that the natural degree of polymerization of cellulose fibers was affected by UV radiation. This was estimated by measuring the relative viscosity of cellulose solution and compared to that of cellulose fibers before treatment. This is also true for the effect of heat on cellulose fibers especially in the presence of oxygen due to the oxidation process. These results were compared with the results obtained for imported cellulose, which was showed that it contains high percent of water vapor, whereas the unbleached cellulose had the higher percent of volatile materials. This reflects the relation between the type of cellulose and it’s sources.
This paper aims at investigating the effect of organic matter content on the engineering properties of the soil. The effect of the organic matter on both the consistency limits and strength have been investigated. The results show that the organic matter increases both the plasticity and the strength of soil. Mathematical formula is presented in which the unconfined compression strength of the soil is related to the organic matter content. It was concluded that increasing the organic matter content increases the displacement corresponding to the maximum shear stress. In addition, the effect of the organic matter has been studied and the results show that the organic matter increases the compressibility of the soil. Stabilizing the soil with cement has been investigated as well. The results show that adding the cement to the soil improves the strength of the soil and decreases its swelling potential. Depending on the organic matter content, a mathematical formula is presented to determine the required cement ratio to treat the soil to decrease its swelling potential.
