Abstract

This study aims to find the effect of water-cement ratio on the compressive strength of concrete by using ultrasonic pulse velocity test (UPVT). Over 230 standard cube specimens were used in this study, with dimensions of 150mm, and concrete cubes were cured in water at 20 °C. Also, the specimens used in the study were made of concrete with varied water-cement ratio contents from 0.48 to 0.59. The specimens were taken from Diyarbakir-Turkey concrete centers and tested at the structure and material science lab, civil engineering, faculty of engineering from Dicle University. The UPV measurement and compressive strength tests were carried out at the concrete age of 28 days. Their UPV and compressive strength ranged between (3.89-4.66km/s) and (17.74-40.56MPa) respectively. The experimental results showed that although the UPV and the compressive strength of concrete are related, also, the UPV and compressive strength have a relation with the rate of the water-cement ratio of concrete.

Abstract

Background: We have taken a standpoint that the scope of the platelet count or its variance is significantly higher in pregnancy; 50,000-6,00, 000 compared to the white blood cells(WBC) 9,000-11,000. Hence, their ratio may be a useful marker in predicting preeclampsia.Aim of the Study: The aim of this study was to verify that placental weight (PW ratio) or platelet/WBC count might be a useful screeningratio for preeclampsia and its related complications. Patients and Methods: We have taken a total of 104 primigravida patients, each one iscorresponding to the gestational ages (GA) 20–34 weeks, and seven patients per each week for initial PW ratio assessment. In addition, allwomen were told to come again at 34 weeks of gestation for reassessment of PW ratio (platelet/WBC) count, and a meticulous ultrasoundexamination for intrauterine growth restriction (IUGR) as well as biophysical profile. Results: At the end of the study, we subdivided the 104initial sample into three subgroups; normal women (n = 76); women with preeclampsia but no IUGR (n = 16); and women with preeclampsiaand IUGR (n = 12). There was a statistically significant difference between the three groups with regard to systolic, diastolic, and PW ratio.In addition, the PW ratio was significantly different among the three subgroups using the analysis of variance test. Nonlinear polynomial ofthe third degree between PW ratio and GA has shown a significant correlation between PW ratio and GA. The correlation between them wasstatistically significant, yet the distribution of PW was normal in distribution P = 0.16. In addition, since all screening test should be subject toWeibull distribution, we challenged the PW ratio against this distribution and was found to be positive P = 0.3 by using the Kolmogorov–Smirnovtest. At last, logistic regression was constructed to evaluate the correlation between PW ratio and the number of infants with IUGR, and ahighly positive correlation was found P = 0.0001. Moreover, PW was significant with all the items of the biophysical profile which includesbody posture, gross body movement, respiratory fetal movement, oligohydramnios, and NST. At last, we have constructed easily used chartand reference tables for PW ratio between 20 and 34 weeks; hence, they can be used in clinical practice to verify this ratio among womenwith preeclampsia. Conclusion: A simple easily to calculate ratio has been constructed which has been shown in this paper to be significantlycorrelated to preeclampsia and IUGR, and from this ratio, easy reference table and figure have been constructed. Yet, by no mean, we call thatthis ratio or table is used as a substitute for clinical methods to screen or to diagnose preeclampsia until its significance is evaluated by furthertrials. However, it may be of value as an adjuvant test to other standard tests used for preeclampsia screening or monitoring.

Abstract

This work seeks to statistically analyze the effect of wavelength transmission in free space over Ilorin, Kwara State, Nigeria using existing atmospheric data for wind velocity from Nigeria Meteorological Agency (NiMET). Scintillation attenuation was calculated based on Rytov approximation for wavelengths of 780nm, 850nm, 1250nm and 1550nm.The signal to noise ratio (SNR) for all the wavelengths considered were also analyzed and it was found that wavelength 1550nm is less attenuated and also has a good SNR as compared with the others. Therefore to improve the efficiency of transmission of FSO, the wavelength of 1550 nm must be used.

Abstract

In this paper, Framelet and Walsh transform are proposed for transformation, and then using arithmetic coding for compress an image. The goal is to achieve higher compression ratio by applying two levels Framelet transform (FLT), and then apply 2D Walsh-Hadamard transform (WHT) on each 8x8 block of the low frequency sub-band, while all other sub-bands are ignored. Experimental results show that the proposed algorithm gets best possible solution for tradeoff between compression ratio (size of image) and quality of compressed image, Peak Signal to Noise Ratio (PSNR). The simulation was carried using MATLAB software package version 2014. In this work, experiments were carried out on the gray scale and colored images.

Abstract

Affinity is a term used to describe the amount of the adhesion bond between asphalt binder and aggregate. Adhesion force may be used as indicator to the amount of energy or work required to breakdown the adhesive bond between asphalt binder and aggregate. In order to study affinity between asphalt binder and aggregate, a modified device is manufacture locally similar to Rolling Bottle Test (RBT) to Predicted the degree of affinity between asphalt binder and aggregate; taking into consideration mineral composition with physical properties of asphalt binder to measure required force to separate asphalt binder from aggregate surface. In this study, suggest new parameters to represent the stripping or affinity phenomena (affinity and stripping ratio) and the time required to make balance between them.From the experimental work result, the affinity ratio of aggregate brought from Dohuk region was 52 % after 24hr of rolling time period which is less than other type because of its mineral composition (high percent of calcite and dolomite which increase ability to resist stripping), pore size and stiffness of aggregate particle. In other hand, the stripping ratio of aggregate brought from al-Taji quarry was 80% after 24hr of rolling time which represent worse case in affinity of aggregate-asphalt binder system due to increased percent of quartz in mineral composition (greater than 80%) and so reduced ability of aggregate to resist stripping

التقارب هو مصطلح يستخدم لوصف مقدار قوة التلاصق بين رابط الإسفلت والركام. يمكن استخدام قوة التصاق كمؤشر لمقدار الطاقة أو العمل المطلوب لتفكيك قوة التلاصق بين رابط الإسفلتي والركام. من أجل دراسة نسبة التقارب بين رابط الإسفلتي الركام ,تم تصنيع جهاز معدل محليًا مشابه لجهازفحص دوران الزجاجة (RBT) لتقدير درجة التقارب بين رابط الإسفلتي والركام ؛ مع الأخذ في الاعتبار تكوين المعادن مع الخصائص الفيزيائية للرباط الإسفلتي لقياس القوة المطلوبة لفصل الرابط الاسفلتي عن الركام. في هذه الدراسة اقترحت مصطلحات جديدة لتمثيل ظاهرة التعرية أو التقارب هي (نسبة التقارب والتعرية) والوقت اللازم لتحقيق التوازن بينهما. من خلال نتائج الفحص التي تم التوصل إليها، كانت نسبة تقارب للركام من منطقة دهوك بنسبة 52٪ بعد 24 ساعة من فترة الدوران اكثر من النوع الآخر بسبب تركيبتها المعدنية (نسبة عالية من الكالسيت والدولوميت التي تزيد من القدرة على مقاومة التعرية) ، وحجم المسام و صلابة الجسيمات الكلية. من ناحية أخرى، كانت نسبة التعرية للركام من مقلع التاجي 80٪ بعد 24 ساعة من وقت الدوران والتي تمثل حالة أسوأ في تقارب نظام الربط بين الأسفلت والركام بسبب زيادة نسبة الكوارتز في تكوين المعادن (أكبر من 80٪) وبالتالي انخفاض قدرة التلاصق على مقاومة التعرية.

Abstract

The aim of this study to determine how tolerant wheat genotypes to drought stress. Three drought tolerant Triticum aestivum L. genotypes; Rizgary, Sham-6 and Abu-Ghraib compared with three drought-susceptible; IPA95, Tammuz-2 and IPA99 under water deficit 20% WHC (Water Holding Capacity). ABA level, drought related parameters; shoot and root dry weights, root and shoot ratio. As well as Leaf relative water content (LRWC %), membrane stability index (MSI %) and proline content determined in the leaves. A considerable increase of ABA noted in drought tolerant as compared to susceptible genotypes under drought stress condition. That is led to reduction in shoot dry weight in Rizgary, Sham-6 and Abu-ghreb; 2.71, 2.70 and 2.62 g/plant respectively. In addition they adapted to proliferate larger root system with 2.63, 2.16 and 1.71 g/plant respectively. Consequently the ratio of root: shoot increased; 0.98, 0.80 and 0.66. Rizgary, Sham-6 and Abu-ghreb retained a significantly higher LRWCs %; 79.81, 77.17 and 78.53 % respectively at 20 % WHC as compared to susceptible genotypes. Membrane Stability Index (MSI %) decreased significantly at lower rate in tolerant genotypes; 65.69, 67.28 and 67.18 % respectively. As well as proline increased as an osmoticum to reduce the harmful effect of drought on plant cell in resistant genotypes; Rizgary, Sham-6 and Abu-ghreb; 0.71, 0.72 and 0.61 mg g-1 D. in sequence as compared to sensitive genotypes. The tolerant genotypes have stronger adaptability mechanisms to cope water scarcity as compared to susceptible genotypes.

Abstract

Ground states bands (GSB) and negative parity band (NPB) of (_ ^(164-174))W isotopes have been calculated. Bohr-Mottelson (BM), Interacting boson approximation-1(IBM-1) and Interacting vector boson model (IVBM) were used for this purpose. The principal excited state ( ) and the proportion of the second to the primary excited state (R_(4⁄2)=(〖E4〗_1^+)⁄(〖E2〗_1^+ )) provide primary information about the properties of the nucleus. The ratio of the gamma energy, over spin E_γ⁄J of each state as a function of the angular momentum (J) (E-GOS), has been assessed to decide the ground states property of each nucleus. The ratio of energies of (J+2) and (J), states as a function of the angular momentum (J), have been attracted to decide numerically the properties of the ground states band of all states and all nuclei. The ΔJ=1 staggering between octupole band and ground state band is found to display a beat pattern as a function of angular momentum (J). The methods which were used, showed the transitional U(5)-O(6) properties of (_^(164-166))W, the general properties that U(5)-O(6)-SU(3) of (_^168)W, and the transitional properties O(6)-SU(3) of (_^(170-172))W; while (_^174)W showed the SU(3) properties.
