Abstract

The increasing of road material demand particularly on mineral filler and additives has been followed-up by finding the new alternative materials. Local materials such as Portland cement, and lime may potentially use to substitute current need. Therefore, it is essential to study the performance and durability of these materials in HMA mixture. To find the durability index, the specimens are immersed around 0 (unconditioned) to 14 days at 60ºC and tested by using Marshall and ITS tests. Based on Marshall test, the index values for mixes variations; DCF, DPC, DL, DPF, and DC are found to be; 42.965%, 36.59%, 36.582%, 35.68%, and 33.42% respectively.

Abstract

This study is an experimental investigation of the effects of methanol addition to gasoline on the performance (brake power, brake specific fuel consumption), and emissions (carbon monoxide CO, hydrocarbons HC) of a spark ignition engine, engine vibration was also measured (Acceleration). The tests were carried out at constant throttle variable speed condition operating with standard and advanced spark timing (10˚ and 11˚ BTDC respectively) over the range of speed from 1500 to 2250 rpm and compression ratios CR=8 and 9 using various blends of methanol/gasoline 0% (M0), 5% (M5), 10% (M10), 15% (M15) and 20% (M20) methanol by volume. The experimental results showed that for standard spark timing, maximum power was obtained at M10 CR9 by increase of (18.29%) from M0. While for advanced spark timing, maximum power was obtained at M20 CR9 by an increase (18.27%) from M0. Advancing spark timing resulted in power increase by (13.4%) from standard spark timing. Optimum compression ratio for gasoline fuel was 8 while for methanol-gasoline blends was 9. Emissions of CO and HC were decreased significantly by using methanol as fuel additive and increasing methanol content in the fuel. M0 exhibited the lowest and most stable acceleration level at higher engine speed at CR8 (2000-2250 rpm). While for CR9, M5 generally showed the lowest acceleration values for lower and higher engine speeds. M15 fuel blend, showed maximum acceleration level compared to other fuel blends.

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

The research deals with some elements of the artistic performance in Ibn Hudhail Al-Qurtubi's poetry, namely: the artistic unity and the building of the poem, photography and imagination, and the colors of the creative, and emotion.In it it will appear that Ibn Hudhail's poetry is dominated by graphic workmanship, as the poet often seeks the artistic image, so that he has a purpose in itself. , The emergence of varying in poetry between weakness and strength, while the enhancements Albadia has been dealt with in moderation and economy without cost.Ibn Hudhail's poetry, with its elements of artistic performance, is considered an artistic and literary ammunition worthy of study and study.

يتناول البحث بعض عناصر الأداء الفني في شعر ابن هذيل القرطبي، وهي: الوحدة الفنية وبناء القصيدة، والتصوير والتخييل، والألوان البديعية، والعاطفة.وفيه سيظهر أن شعر ابن هذيل تغلب عليه الصنعة البيانية، إذ يسعى الشاعر غالبًا وراء الصورة الفنية، حتى أصبحت عنده غرضًا في حدِّ ذاتها، وهذا التوجُّه مكَّنَ الشاعرَ من تحقيق الوحدة العضوية، وإبداع صورٍ فريدةٍ في مجال الوصف الذي برع فيه، لكن أثَّر في العاطفة، فكان ظهورها متفاوتًا في أشعاره بين الضعف والقوة، أما المُحسِّنات البديعية فقد تناولها باعتدال واقتصاد دون تكلُّف.ويُعدُّ شعر ابن هذيل، بما احتواه من عناصر الأداء الفني، ذخيرةً فنية وأدبية، تستحق الوقوف والدراسة.

Abstract

Background: Gestational hypertension represents a transient period of elevated blood pressure with special effects on the maternal left ventricle that is different from the effects observed in chronic essential hypertension; it affects a previously normal heart and lasts for a maximum of nine months associated with volume and pressure overload on the maternal heart. Tei index (also called myocardial performance index) was found to be a dependent combined index evaluating the systolic and diastolic function of the left ventricle and represents a sensitive indicator for many types of heart diseases.Objective: to evaluate the effects of gestational hypertension on the maternal myocardial function during the third trimester by measuring the Tie index using transthoracic echocardiography.Method: This study was performed in Baghdad teaching hospital in the time period from November 2015 to August 2016. The study included a total of 150 women; 100 women had gestational hypertension, in the third trimester of a singleton pregnancy and with a mean age (29.83 ± 5.33 year), gestational hypertension was identified as elevated systolic or diastolic blood pressure over 140/90 mmHg that emerges after the 20th week of gestation with proteinuria level lower than 300 mg/dl. Another 50 normotensive pregnant women with singleton pregnancy and mean age (28 ± 3.18 year) were used as controls. Left ventricular mass index (LVMI) and relative wall thickness (RWT) were measured to find the type of hypertrophy in gestational hypertension. Ejection fraction (EF) was measured with 2D directed M mode echocardiography, and isovolumic relaxation time (IVRT), isovolumic contraction rime (ICT) and ejection time (ET) were measured for both groups using pulse wave Doppler echocardiography in order to calculate the myocardial performance index which is also called “Tei index” and equals the sum of IVRT and IVCT divided by the ET (Tei index = IVRT+IVCT/ET).Results: Left ventricular mass index and relative wall thickness were significantly higher in gestational hypertensive women, 41% of gestational hypertensive women had normal geometry and 59% had abnormal geometry (34% eccentric hypertrophy, 19% concentric hypertrophy and 6% concentric remodeling). IVRT and IVCT were significantly higher in gestational hypertensive women with p value of 0.0001 and P = 0.003. ET showed a non-significant lower values (p= 0.34) in gestational hypertensive women. Tei index was significantly higher in Gestational hypertension (P=0.011).Conclusion: Women with gestational hypertension had altered myocardial function characterized by the higher Tei index values associated with eccentric hypertrophy which can be explained by the fact that gestational hypertension poses higher afterload on the left ventricle instead the state of low peripheral resistance that is ysually expected during normotensive pregnancy.Keywords: Echocardiography; Gestational hypertension; Myocardial performance.

Abstract

The performance evaluation as a judgment on the administration's ability to over exploit the resources available to it as rational, it is an objective and systematic analysis of a record of the activities of the company to determine the degree of success in achieving the goals set process. As a result of the intensification of competition and the development taking place in the traditional production systems of performance evaluation models are no longer (standard costs , budgets , financial analysis) enough being based on historical data, and rely only on the financial measurements and analyzes. So it was adopting the model of balanced performance, which is newly input into the performance evaluation card being contain financial indicators and non-financial interconnected within is based on the relationship of cause and effect strategic framework, works this model to achieve a balance among the four perspectives (financial, customers, internal operations, learning and growth) within a single report and under the umbrella of the company's strategy. On this basis, the Balanced Scorecard is considered a strategic framework helps in the various levels of the company to translate its strategic objectives and plans to measurable targets process
