Vertical Resistance and Its Relationship with Speed-Strength and Biomechanical Variables During the Takeoff Phase and the Performance of Selected Activities in Individual and Team Sports
...Show More Authors

Jumping ability is a fundamental variable in many sports, as its execution requires an integration of muscular strength Q1 and certain biomechanical variables. This is particularly evident in gymnastics jumping events and jump shots in ball games, both of which rely on a high level of vertical resistance. Vertical resistance serves as an indicator of an athlete’s ability to overcome their body weight while counteracting gravitational force to achieve optimal performance. As such, it is considered one of the key factors in movements that demand explosive power and speed. The researchers believe that despite the significant relationship between vertical resistance, speed-strength of the arms and legs, and certain biomechanical variables in determining athletic performance across various sports activities, the limited number of studies addressing this relationship makes it difficult to provide precise scientific data on its importance. This is particularly relevant to female students in the College of Physical Education and Sport Sciences, who often struggle with performing activities that require jumping or shooting while airborne with proper technical execution. This underscores the need for a more comprehensive and in-depth study of the factors in uencing such performance. This research aims to bridge the existing knowledge gap by analyzing these relationships among a sample of female students from the College of Physical Education and Sport Sciences for Women. The study seeks to highlight the key factors affecting student performance. Accordingly, the research problem is framed in the following question: What is the relationship between vertical resistance, physical abilities, biomechanical variables, and the execution of sports activities (high jump, jump shooting, and vaulting) among third-year female students? The study aimed to examine the relationship between vertical resistance, speed-strength of the arms and legs, and certain biomechanical variables during the take-off phase, as well as their impact on the execution of vaulting, jump shooting accuracy in handball, and jump shooting accuracy in basketball. The researchers hypothesized that there is no statistically significant relationship between vertical resistance and speed-strength, nor between vertical resistance and certain biomechanical variables during the take-off phase. Additionally, they posited that no statistically significant relationship exists between vertical resistance and the performance or accuracy of the examined activities. Adescriptive research methodology was employed, with the study sample consisting of eight third-year female students from the College of Physical Education and Sport Sciences for Women, selected through purposive sampling.

Bionic and its reflections in the design of industrial products
...Show More Authors

The current research dealt with the development of sciences and arts over the course of human history, and the development of sciences with their natural and human trends are important areas in developing the knowledge and application base for industrial product design and design in its various fields. Bionic science is one of the sciences that works on applying biological methods and systems found in nature to study and design engineering systems and modern technology, and for industrial products to be highly efficient, durable and resistant to natural variables in daily life for use. The transfer of technology between life forms and industrial products is desirable because the processes of development at the level of science in general

The concept of peaceful coexistence and its obstacles in Iraq
...Show More Authors

This research deals with the study of the obstacles to peaceful coexistence in Iraq. Therefore, our hypothesis is that these obstacles are not attributed to one reason or to one source. Therefore, peaceful coexistence among the components of Iraqi society remains fragile and vulnerable to collapse and threat at any moment. This society, which is already in need of social relations, needs more than ever to coexist and consolidate it. Through the exercise of democracy in Iraq in a manner that guarantees rights and duties for all, to restore mutual trust between the components of this community in a way that feels they are citizens of the state.

Value Engineering and the Possibility of Its use in Architecture
...Show More Authors

Value Engineering is an analytical study on projects or services using a specific procedure and a multidisciplinary working group, works for the identification and classification of the project functions; either for a better perfuming of these functions or to lessen the total project cost or the two together. Value Engineering main aim is on finding innovative alternatives, without effecting the basic requirements of the project, its methodology based on the functional balancing between the three elements of production "performance, quality and cost". This methodology based on the "functional analysis", had shown high possibilities in solving any problem facing the production procedure , achieve better investment for available re

Westernization in the sciences of rhetoric, its beginnings and development
...Show More Authors

Research summary

 


Westernization is a term not familiar to our scholars at the beginning of the emergence of translation from Western literature, sciences and arts in its detailed form now.

Westernization was not an issue that those Greeks, Persians, Romans, Indians and others worked on translating those sciences and cultures. Rather, it was a process of transferring a new philosophy and logic that had not been previously seen by the Arabs, so they were affected by it in a strange way, to the point of fascination by some of them. For this reason, this research came to clarify these issues and address them within the scientific methodology.

Design and Implementation of Single-Phase Boost PFC Converter
...Show More Authors

In this paper, a single-phase boost type ac-dc converter with power factor correction (PFC) technique is designed and implemented. A current mode control at a constant switching frequency is used as a control strategy for PFC converter. The PFC converter is a single-stage singleswitch boost converter that uses a current shaping technique to reshape the non-sinusoidal input current drawn by the bulky capacitor in the conventional rectifier. This technique should provide an input current with almost free-harmonics, comply with the IEC61000-3-2 limits, and a system operates with near unity power factor. The other function of the boost converter that should be
accomplished is to provide a regulated DC output voltage. The complete designed

EXPERIMENTAL AND THEORETICAL STUDY OF TWO-PHASE HEAT PIPE
...Show More Authors

In this study, thermal characteristics of a two-phase closed heat pipe were investigated experimentally and theoretically. A two-phase closed heat pipe (copper container, Fluorocarbon FC-72 (C6F14) working fluid) was fabricated to examine its performance under the effect of input heat flux range of 250–1253 W/m2 , 70% fill charge ratio and various tilt angles. The temperature distribution along the heat pipe, input heat to evaporator section, and output heat from condenser were monitored. A comprehensive mathematical model was developed to investigate the steadystate heat transfer performance of a two-phase closed heat pipe. A steady state analytical model, is presented to determine important parameters on the design of two-phase close
