Application of Building Information Modelling in Construction Projects

2022-10-01T08:19:42+00:00

In recent years, building information modelling (BIM) has been one of the most popularly debated topics in journals on technological progress in construction projects. In the construction project model that is built and applied via a collaboration network, the BIM concept incorporates all tasks related to planning, construction and operation. The paper of focus is applied risk and change management focusing on the building information modelling (BIM) from the perspective of from the point of view of the construction projects management theory and structure. However, negative affects such as setbacks and financial damages to the detriment of participants' public projects, in particular, pose a concern as to whether and how the application of BIM standards will enhance management practices in the context of construction projects correlated with risk. This paper aims to deal with the current situation of building projects, information about risk and change management in the construction project, as regards the application of BIM, and to guide further studies. The arguments highlighted in this paper are using in the analysis of many reference kinds of literature. However, the risk is a subject that should always be established in the concept of BIM. An effective way to combine risk construction projects processes, practises and strategies with other management actions for construction projects within BIM must be created. Moreover, change is considered one of the main factors in risk and the incorporation into this framework of change management processes includes the introduction of guidelines and methodological approaches within BIM. In addition to that studies on this field includes previous expertise in implementing BIM in construction programmes, the involvement in this point of risk-related processes and requirements for successful coordination of management.

HighTeach: A Web-Based Teacher Evaluation System for a Higher Learning Institution in the Philippines

2022-10-01T08:25:39+00:00

The study is primarily aimed at describing how to design and develop a teacher evaluation system for a higher learning institution in Nueva Ecija, Philippines. Specifically, it sought to describe the activities undertaken in the software development lifecycle stages, including planning and requirements analysis, design, development, and testing. Maintenance and deployment stages were not covered in this study. Using developmental research, proponents developed the system following the SDLC stages. The results show how the proponents successfully developed the system. Proponents suggested that future studies may be conducted which may focus on the assessment phase covering deployment and maintenance stages, to learn how end-users and information technology (IT) experts view the developed system.

Molecular and Biochemical Study for (VDBP) gene in women Suffered with osteoporosis in Mosul City

2022-10-01T08:55:54+00:00

An The GC gene encodes the protein VDBP, which plays an important role in the transport of vitamin D. This protein belongs to the albumin family. The GC gene is located on the long arm of chromosome 4 (4q12-q13), which consists of 1690 nucleotides, and the GC gene has many genetic variations that are related to variation Single nucleotide SNPs and the proteins resulting from these variations differ in their ability to bind with VD and its different forms. due to the presence of two genetic variations, rs7041 and rs4588 for VDBP, three phenotypes were identified which are Gc1s, Gc1f and Gc2, which differ in their ability to bind to the inactive form of vitamin D 25(OH)D3. It has been proven that the variants in this gene change the concentrations of OH-D325 in the plasma, so the defect in these variants of the VDBP gene is closely related to many diseases, including VD deficiency and cancer. The current study included (96) women with ages ranging between (45-35) years who were referred to the private pathological analysis laboratories in the city of Mosul in a period of time that ranged from September to November of 2021. The samples were divided into two groups, the first included 25 women who returned as a control group. The second included 71 women with VD deficiency. The concentration of vitamin D (OH) D325 in the serum is widely used to determine the deficiency in the level of VDBP.

pH Evaluation of some Skin Cleansers in Sabratha, Libya

2022-10-01T09:00:59+00:00

The present investigation was carried out to determine the pH values of some Skin Cleansers in Sabratha, Libya. Twenty-four different Samples of branded shower gel, liquid soap and shampoos, were random collected. According to the standard method ASTM D1172, pH values were measured using WTW-Multiline P4 pH meter. The experimental obtained results were analyzed and presented graphically. The majority pH values of shampoo were acid balanced and the rest of shampoo samples tend to be neutral. 50% of the pH values of Shower gel and liquid soap were acidic and the other 50% of the pH values tend to be neutral. The majority pH values of shampoo were acid balanced and the rest of shampoo samples tend to be neutral. 50% of the pH values of Shower gel and liquid soap were acidic and the other 50% of the pH values tend to be neutral.

تقييم بعض الخواص الفيزيوكيميائية ونسبة النشاء المتضرر للدقيق المدعم ببعض أنواع البقوليات

2022-10-01T09:09:48+00:00

هدف هذا البحث دراسة بعض الخصائص الفيزيائية والكيميائية ونسبة النشاء المتضرر لمزائج من دقيق القمح مع دقيق العدس ودقيق الحمص وذلك وفقاً لنسب استبدال (7% و12% و17% و22% و27% و32%) لكلاً منها، وذلك باستخدام بعض التقنيات الحديثة لدراسة نسبة النشاء المتضرر باستخدام جهاز SD matic وجهاز المكسولاب، وأُجريت كافة التحاليل في مخبر تكنولوجيا الحبوب، جامعة الفرات.

أظهرت نتائج تقدير متوسط نسبة البروتين وجود ارتفاع وبشكل معنوي مع ارتفاع نسب الاستبدال من دقيقي العدس والحمص، بالإضافة إلى ارتفاع في قيمة رقم السقوط وبلغت مع نسبة الاضافة (17) % من دقيق العدس (513) ثانية ومع دقيق الحمص (474)، بالإضافة إلى ارتفاع زمن امتصاص اليود الى 66 ثانية مع نسبة الخلطة 7% من دقيق العدس.

كذلك وجد ارتباط معنوي بين المقاييس المختبرة لجهاز SD matic ولم يلاحظ أي ارتباط بين زمن امتصاص اليود وباقي المقاييس، ويمكن توجيه الخلائط المختبرة إلى صناعة الخبز وذلك حسب طريقة UCD.

حل سلاسل ماركوف بالمصفوفة العشوائية

2022-10-01T09:19:41+00:00

تناول هذا البحث دراسة عملية ماركوف وهو نموذج مؤشر عشوائي يحتوي علي خاصية ماركوف ويمكن استخدمه في تصميم نموذج عشوائي الذي يتغير وفقا لقاعدة التحول، وتستخدم عمليات ماركوف في كثير من المجالات منها: تعلم الآلة (التعلم المعزز) والتعرف علي الأنماط وتشخيص الأمراض وقرارات العلاج وبشكل خاص يحتاج مؤشر المعلمة الدولة الفضاء والوقت النظام علي ان تكون محددة، ويوجد حالات مختلفة من عملية ماركوف لمستويات مختلفة من الحالات عموماً وللزمن المتقطع مقابل الزمن المتواصل، سلاسل ماركوف لديها العديد من التطبيقات تقنيات الحوسبة والانترنت.

المشكلة الأساسية من قرارات عملية ماركوف هي العثور على السياسة لصانع القرار، وهي تهدف إلى اختيار السياسة التي تقوم بتعظيم بعض الدوال التراكمية للحالات العشوائية، ويمكن لقرارات عملية ماركوف أن تحل من خلال البرمجة الخطية والبرمجة الديناميكية.

حيث تم دراسة سلاسل ماركوف وخاصيتها، ومصفوفة العشوائية وانواعها، تم تطبيق سلاسل ماركوف بالمصفوفة العشوائية باستخدام برنامج (Maple)، تم ايجاد القيم الذاتية والمتجهات الذاتية واستقراريه حلها.
