Our aim was to investigate the changes in the myocardium stiffness index for patients suffering from systemic hypertension, and to assess their left ventricular performance. We studied 263 hypertensive patients and 166 healthy subjects as a control group. By using conventional Doppler echocardiography, the following parameters were measured—Left ventricular end diastolic diameter, left ventricular end systolic diameter, transmitral early velocity, isovolumic relaxation time, and isovolumic contraction time. Tissue Doppler imaging (TDI) was used in the measurements of the early mitral annular velocity (Ea) and the diastolic stiffness was obtained by calculating the ratio E\Ea\LVIDd. Index myocardial performance (IMP) was calculated according to following equation (IVCT + IVRT)/ET for both the control group and hypertensive group. Results reveal that the differences in the average value of transmitral early filling velocity (E) between patients and control groups for age range (20 - 49) and (50 - 80) were (−1.91%) and (−3.69%) respectively with p value >0.05 for both groups, and the changes in LVIDd between patients and control groups were 0.42% and 1.29% for age ranges (20 - 49) and (50 - 80) respectively with p value >0.05 for both age groups. A significant difference in IMP between patients and controls has also been observed and the changes were 29.54% and 30.43% for age range (20 - 49) and (50 - 80) respectively with p value <0.05 for both groups. The mean values for E/Ea ratio and for the measured LV stiffness index were significantly higher in hypertensive patients compared with control group (p value < 0.05) for both age groups. In conclusion, LV myocardial diastolic stiffness index and IMP are increased in hypertensive patients.
The research addresses smart city concept as it is the latest urban design trends, by the investment of the capabilities of human, and artificial intelligence for the sake of the advancement of the city. The concept of a smart city is described as one of the most important manifestations of the information revolution, with the end of the twentieth, and the beginning of twenty – first century, The research attributes the emergence of the concept to: deficiencies of means, and traditional methods in building and development of cities, as well as The significant increase in the number of city and global metropolises dwellers. So, smart city approach has been adopted, along with innovative principles and methods which cons

The aim of this paper is an attempt to compare some possible combinations of diversity reception and MLSE detection techniques. Various diversity combining techniques can be distinguished: Equal Gain Combining (EGC), Maximal Ratio Combining (MRC), Selection Combining and Selection Switching Combining (SS).The simulation results shows that the MRC give better performance than the other types of combining (about 1 dB compare with EGC and 2.5~3 dB compare with selection and selection switching combining).
Sustainability is a concept embodied in traditional architecture around the world since ancient times through spontaneous experimental compatibility with the environment and efficient exploitation of the natural resources of the environment according to a rapid development of trial and error over the years . Architecture was the basic means that man devised to protect him from the harsh conditions of the external environment by exploiting natural energy sources such as the sun, wind, and soil capabilitie, Many of the principles of sustainability overlapped with the social organization and human behavior of the community as it was reflected in the urban production at the level of standards of city planning and urban agglomerations as well

They play an important role in facilitating the process of communication between the institution and its audiences and achieve mutual understanding between the parties as public relations play this important role based on research and analysis, policy formulation and programming programs and communication with the public.
The significance of this research comes from the challenges faced by public relations in state institutions. Misunderstandings and ambiguities still plague most workers in this field, especially in defining the concept, objectives and basic functions of public rela
... Show MoreDomestic violence, or as sometimes known as family abuse, is usually related to a domestic or local setting as in cohabitation or in marriage. It can take the forms of being physical, verbal, economic or emotional. Globally, most of the domestic violence is overwhelmingly directed to females as they tend to experience and receive severe forms of violence, most likely because they do not involve their intimate, or sometimes even non-intimate partners, in the process of mental and physical self-defense. Sometimes countries justify domestic violence directed to females, they may be legally permitted when the reasons behind it are related to issues of women's infidelity. Usually, the permission to violent acts is related to

Show MoreThe cinematic medium consists of a group of elements that overlap with each other in balance, giving it its high influential capabilities, and the character is one of the most important of these elements, as it performs a set of important functions, foremost of which is the transmission of the main ideas to the recipient, and since cinema is an art closely related to the intellectual data of the worlds outside it, it is influenced by them and then reproduces them intellectually more deeply and with a higher vitality through its intermediate elements, including the character, to re-broadcast them to society with a retrograde movement, and the character of the prisoner is one of the cinematic characters that achieved this goal, as we can infe

Show MoreThe aim of this research is to identify the level of mental mindfulness among female students of the College of Education at Umm Al-Qura University, as well as to identify the statistically significant differences in the level of mental mindfulness according to academic level, specialization, and academic achievement. A mental mindfulness scale was designed to cover five dimensions. The study employed the analytic descriptive approach applied to a random sample of (217) female students from various academic specializations. The findings indicated that the level of mental mindfulness was average among female students. Statistically significant differences were attributable to the academic level, academic specializations, and academic achi
