جذبت الخرسانة فائقة الأداء الاهتمام في المنشآت الهندسية في الآونة الأخيرة حيث أنها ذات مقاومة و صلابة عاليتين. إن ما يقدمه ال UHPC من مقاطع صغيرة يبرر استخدامه في الأبنية العالية للاستفادة من مقاومته الكبيرة للضغط و الشد . تم استخدام هذه المادة في الجسور لما تملكه من مقاومة عالية مما يتناسب مع الحمولات الكبيرة و كذلك كمادة صالحة للعوامل الخارجية مما يؤمن ديمومة أكبر للمنشأة . مما برر لنا التفكير في استخدام الخرسانة فائقة الأداء في الأبنية العالية كونها منشآت مكلفة و يلزم الإستفادة منها لأطول فترة ممكنة . درسنا عدة نماذج من الأبنية متعددة الطوابق و باستخدام الخرسانة فائقة الأداء و تمت مقارنة ما حققته هذه المادة من نتائج في تخفيض الإنتقالات مع نموذج أساسي الخرسانة العادية هي مادة البناء فيه. و وجدنا بعد التحليل كفاءة عالية لهذه المادة و خاصة في ديافرامات البلاطات .
Ultra-High-performance concrete (UHPC) attracted attention in the civil engineering industry in recent times, because it has high resistance and rigidity . What provided the UHPC of skinny clips justifies using it in high buildings to take advantage of pressure and tensile its resistance . The largest use of this material in the bridges because of its high resistance which suitable for large loads as well as a valid treated outside the center and sustainability of the high buildings, We study several models of building and we use this material in several elements of these . We found after analysis of the high efficiency of this models, especially in Diaframat.

This research aims to check the actual performance of the work of the propeller
depending on series of results issued from Hamburg basins that are known by RANSE
where the arcs analysis and the hydrodynamic characteristics of the propeller work in
open
water are done by using the commercial program CFD Analysis m by Hydro Comp.
Thus, the results were compared with the experimental data and the study of fluently
around the different parts of the ship and the definition of resistance values and friction
factor CF. These values were compared with those issued by ITTC basins and coincidence
was found between those of RANSE and the experimental values in the different stages of
study.
Therefore, a collection of solutions related to the work of propeller were achieved in
addition to the evaluation of the level of interaction and the exchanged effect of the
propeller work in different conditions, and the definition of degree of difference resulted
from the values of the rotation moment and the factors of advance and control the are
resulted from the use of CFD program. The numerical results and the syntheses data were
discussed in case of working in open water.
This study presents definition of the types of lightweight concrete and
some studies, which use the volcanic scoria aggregates to produce
structural lightweight concrete.
Several concrete mixes were designed, and different tests were
performed to
determine its properties.
This paper studies a practical laboratory research of the possibility of utilizing the
natural resources available in the country, namely Basalt, which is available in large
quantities in the southern region (Al-Suwayda) in order to demonstrate the
extent to which
it meets the requirements of standard specifications for use in the manufacture of
(Reinforced) concrete by means of testing the resistance of pressure and tensile by
splitting and the elasticity coefficient of hardened (rigid concrete) at Different ages (3-7-
28) days.
As a result, pressure resistance tests increased by approximately 20 % with the
maturating period progress of concrete mixtures.
The pressure resistance of concrete mixtures prepared using basalt pebbles was
approximately 18% higher than the pressure resistance of concrete formed
usingcalcite(calcareous) pebbles in ages above 7 days
There was also a slight decrease of 8% in the split tensile resistance of the studied
samples prepared with basalt minerals , compared with the samples prepared using calcite
(calcareous) pebble and this resistance increases over time .
As for the elasticity coefficient , a 20% increase in the elasticity coefficient of the
concrete was noticed with the maturating of the concrete mixtures compared to the
referential mixture.
Health of citizens considers a prime target for all forms care, which tends approaching entrusted with the provision of medical health care services and nursing towards providing the necessary about it. But it is clear from the experience the daily r
eality it is necessary to improve the the performance of health care. The nursing services of key resources that will ensure access to the aspirations of the communities of development, health and wellness.
Where nursing is a backbone of any health care and a cornerstone of its corners in all parts of the world, therefore, the quality and performance at work is an important part of the quality of health care provided to the patient.
This study aimed to determine the effect of the application of a training program on the quality of nursing performance in measurement of Apgar scale in complex medical Assad in Hama province. The study sample consisted selected 30 nurses form nurses working in neonatal resuscitation department. The result showed Effect the training program to raise the hairy-quality ratio performance in measur4ement of Apgar scale.
Where the percentage of hairy quality of the experimental group before the application of the program 57%, after the application of the program directly 95%, and after three months 84%, while the percentage remained comparable t5o the control group that were not applied to the training program and stood before the application of the program 60%, after the application of the program 58%, and after three months 59%, which indicates that there is no change in the performance of nursing through three stages.
This research evaluates the performance degradation of information channels in
multifunction radar due to electronic countermeasures (standoff jamming) on main loop
of radar antenna .This evaluation is performed by using the signal to noise ratio(
SNR )
and the probability of detection parameters with and without jamming.
Improvement of radar performance is proposed by using the following (ECCM)
techniques :Constant False Alarm Rate( CFAR), Pulse compression (pc) , frequency agility
(FA), Frequency Diversity(FD),Logarithmic Reception , and Automatic Gain
Control(AGC).
In this research MATLAB, software environment is used that has advanced
mathematical tools, and graphical interactive ability.
