Abstract

In Iraq, as well as many other developing countries the performance graded (PG) based System is not yet implemented to evaluate the currently used asphalt cements for paving works. It appears that not only the unavailability of test equipments is resulting in this delay but also the lack of clear understanding of what steps could be taken to incorporate this system. This research is an attempt to highlight the important aspects of a (PG) system that can be readily implemented without the need for expensive equipments. It includes the development of a Performance based System employing the conventional test methods and available nomographs from literature. It also, shows how climatic data, traffic data, and asphalt binder properties can be combined to propose a possible major improvement for the specifications of asphalts in Iraq. To achieve the objective of this research, an extensive air temperature data for a period of 18 years was reviewed for five cities (Mosul, Kirkuk, Rutba, Baghdad, and Basrah) to establish the required PG asphalt binder for each city. Also, the currently used asphalt cements with penetration grades (40-50) and (60-70) were tested by both of conventional test methods and Superpave methods to determine the equivalent performance grade for each type of the penetration graded asphalt and to evaluate the capability for these two types of asphalt cement to satisfy the required performance of pavement for each city. The results indicate that both the new proposed method and Superpave method give the same final performance grade, The asphalt with penetration grade 40-50 is equivalent to PG70-16 while that with penetration grade 60-70 is equivalent to PG64-16.

في العراق وفي كثير من الدول النامية لم يطبق نظام تدرج الاداء (PG) لتقييم الاسفلت المستخدم في اعمال التبليط لغاية الان. لقد تبين ان الكلفة لم تكن وحدها سببا" في هذا التاخير بل النقص في فهم الخطوات التي يجب ان توخذ لتطبيق الفقرات الخاصة بهذا النظام . في هذا البحث تم القاء الضوء على الاقسام المهمة الخاصة بنظام تدرج الاداء والتي يمكن تطبيقها دون الحاجة الى المعدات المكلفة الثمن وذلك عن طريق استخدام الطرق التقليدية لفحص الاسفلت في العراق. لقد بين البحث كيفية استخدام نتائج هذه الفحوصات بطريقة غير مباشرة لتخمين الخصائص المتعلقة بالاداء بناءا" على مخططات بيانية (nomograph ) وبين كيف يمكن للبيانات الخاصة بالطقس والبيانات المروية والخصائص الريولوجية او خصائص الفشل التي اشتقت من المخططات البيانية ان تشترك فيما بينها لاقتراح تطوير لمواصفة الاسفلت في العراق.لتحقيق الهدف من البحث تم مراجعة بيانات الانواء الجوية العراقية وجمع المعلومات المتعلقة بدرجة حرارة الجو خلال فترة 18 سنة ولخمسة مدن عراقية (موصل، كركوك، رطبة، بغداد، والبصرة) وبناءا" على نظام تصنيف الخرسانة الاسفلتية العالية الجودة ( (Superpaveتم استنباط تدرج الاداء الخاص بكل منطقة. كذلك تم فحص الاسفلت السمنتي ذو درجة اختراق (40-50) و (60-70) باستخدام الطرق التقليدية و طريقة ((Superpave لحساب تدرج الاداء لكل نوع وتقييم مدى ملائمة هذين النوعين لكل منطقة.لقد بينت النتائج بان كلا الطريقتين ( الطريقة المقترحة وطريقة Superpave) قد اعطت اقيام متماثلة لتدرج الاداء، الاسفلت السمنتي ذو اختراق (40-50) يكافي تدرج اداء PG70-16 والاسفلت السمنتي ذو اختراق (70-60) يكافي تدرج اداء PG64-16.

Abstract

ABSTRACT:BACKGROUND:Current ultrasound assessment of placental calcification relies on Grannum grading. The ultrasonographic appearance of grade III placental maturation, if it occurs before 37 weeks, may signify placental dysfunction and is found to be associated with development of pre-eclampsia and low birth weight.OBJECTIVE:To look at the prevalence of a grade III placenta at 36 weeks’ gestation in a low-risk obstetric population, and to explore the association between premature aging observed ultrasonographically and pregnancy outcome.METHODS:Scans were performed at 36 weeks’ gestation in 591 low-risk pregnant women to determine placental maturity. The prevalence of grade III placenta at 36 weeks’ gestation was determined. Follow-up was performed for the group of women demonstrating a grade III placenta in comparison to those not demonstrating a grade III placenta for determining pregnancy outcome.RESULTS:The prevalence of grade III placenta at 36 weeks’ gestation was 3.9%. A grade III placenta at 36 weeks’ gestation was significantly associated with young maternal age P = 0.01. The Grannum grade III of the placenta at 36 weeks’ gestation was statistically associated with increased risk for development of proteinuric pregnancy-induced hypertention (PIH) later in pregnancy (RR 4.94; 95% CI 1.15-21.26), P = 0.021. Women demonstrating a grade III placenta at 36 weeks’ gestation had a significant high risk of induction of labour for suspected fetal compromise (RR 4.7; 95% CI 1.76-12.59), P = 0.001. The risk for delivering a baby with a weight <10th centile at birth was significantly higher in women with grade III placentas in comparison to those with grades 0-II (RR 3.19; 95% CI 1.23-8.27), P = 0.017.CONCLUSION:In a low-risk obstetric population, ultrasound detection of Grannum grade III placenta at 36 weeks’ gestation helps to identify at risk pregnancy. It appears to predict subsequent development of proteinuric PIH and may help in identifying the growth-restricted baby

Abstract

Abstract: currently asphalt grading in Iraq depend on two types; penetration grade and viscosity grade. These grades did not give impression on asphalt pavement performance because it is depend on fixed temperature test. In this paper Iraq map was developed by using superpave method to find performance grade. High and low pavement temperature was calculated. Contour maps for high and low pavement temperature developed by using geographic information system (GIS). A map presented the temperature zones in Iraq in terms of asphalt performance grade. The data of temperature was taken from 48 weather stations distributed to all region of Iraq. It has been found PG70-10 and PG76-10 covering more than 70% of the parts of Iraq.

Abstract

Abstract:The use of Multiple Choice Question (MCQ) in paper based exams is a very popular choice in the international certificate exams (like TOEFL) because it is very fast to grade and it does not let the student write any unnecessary information. In international tests, a specialized machine is used for grading MCQ paper based exams, this machine is very expensive and it needs a special trained operator to operate the machine correctly and efficiently. This project suggests a method to use a personal computer plus a scanner and a program written in Matlab programming language to grade a specially designed MCQ exam test paper with 15 questions with four choices for each question which the student can choose only one answer per question. The program has been tested to detect the correct answers by comparing each paper with a pre scanned test paper that contains the correct answers, many forms of test papers are used to answer different sets real questions for a real exam that has been conducted in the computer center in the Baghdad University and shown to produce results that matches the results gained from grading the same papers manually. The program is written in such a way that it can tolerate rotating the papers in the scanning operation using the process of image registration, any kind of pencil can be used to make the correct answer no matter its color. The program can detect question with multiple choices and eliminate them from calculations.

Abstract

ackground: The care of pediatric low grade gliomas (LGG) of central nervoussystem in developing countries is still suboptimal. By introduction of chemotherapyand avoiding of radiotherapy in children, better outcome should be achievable.Objectives: to evaluate the impact of replacement of radiotherapy by chemotherapy on the survival rate for children with LGG.Methods: A retrospective study was conducted of records of patients (n=85; 48 males; median age 6 years) with LGG from May 2003 to December 2009 at King Hussein Cancer Center, Jordan. Patient demographics, tumor characteristics, treatment plan, and outcomes were studied.Results: Five-year event free survival (EFS) and overall survival (OS) rates were 60%±7.3% and 92%±4.1%, respectively. The most common tumor site was the Posterior fossa/cerebellum and the suprasellar/hypothalamic area (n=23 each). The most common pathologic diagnosis was pilocytic astrocytoma (n=62). Initial surgical interventions were gross total resection (n=21), subtotal resection (n=20), and partial resection/biopsy (n=39). Posterior fossa tumors were more likely to have gross total or subtotal resection (n=17) compared to tumors in other sites. The most commonly used chemotherapeutic regimen was carboplatin/vincristine (n=29) followed by Vinblastine (n=6). There was a significant difference in the 5-year EFS by the tumor location (P=0.048) and degree of surgical resection (P=0.023). There was no statistical significance in outcome by the type of chemotherapy used (P=0.57).Conclusions: LGG management in developing countries can be improved through a multidisciplinary approach. The main impact of this approach was the elimination of radiotherapy from the management of most patients with LGG.

Abstract

background: Colorectal cancer (CRC) is a major health problem in Iraq. Aim: to identify the clinicopathological characteristics of colorectal cancer in young Iraqi patients in Karbala. Design of study: Retrospective study was conducted in a single center, Imam AL-Hussein general teaching hospital during the period from January 2009 to April 2017. Patients and Methods: A sample size of 96cases of Colorectal Carcinoma was diagnosed during the study period. The clinic-pathological parameters were reported. Results: The mean age of the patients was (51.68). There is a general increase in the incidence of colorectal cancer across the years with percentage of (41.7%) being younger than 45 years. There was slight male predominance. The predominant site of the tumor is colon in (75%) of cases followed by rectum (17.7%). The most common type was adenocarcinoma (82.1%) followed by mucinous type (27.3%), most patients presented with grade I (61.5%). In the majority of patients the malignancy reaching the pericolic fat (54.5%). About (43.6%) of patients presented with N1 and (50.9%) with stage III followed by stage II in (30.9%). For all cancer grades, the frequency of CRC was higher among patients > 45 years with the majority of patients with grade III being younger than 45 years and this make a significant difference between both categories, (P=0.043). With respect to the depth of invasion, those with advance disease (T3), 17 out of 30 cases were younger than 45 years, thus there was significant difference between 2 age groups. Conclusion: the incidence of colorectal cancer is upgrading in those younger than 45 years

Abstract

Primary splenic lymphoma is a rare low‑grade non‑Hodgkin’s lymphoma. This is a case of a 52‑year‑oldwoman who had an incidental detection of a lesion in the spleen during evaluation for fever whichwas found to be a case of primary grade III follicular lymphoma of the spleen. The patient wasstarted on rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapypostsplenectomy. Rituximab was not added initially as the patient had a high viral load of hepatitis Bvirus (HBV). The patient completed six cycles of chemotherapy and rituximab added after four cycleswhen HBV DNA titer became negative. The outcome in patients with primary follicular lymphoma isgood with splenectomy followed by multi‑agent chemotherapy.
