Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

This study was conducted to analysis the effect of Time-OF-Day on physical fitness components for students of Physical Education Department-Duhok University.The aim of this study was to compare the level of some physical fitness components between students of the morning shift and evening shift studies of the first stage in the college of Physical Education, The selected variables for the study were speed by (sprint 60 M test), abdominal endurance by (Abdominal muscles test) , anaerobic power and agility by (5-m multiple shuttle run test) and explosive strength of the arms by (Medicine ball throw test) of both groups were compared by using the statistical package for Scientific Sciences SPSS. The data of this study is not normally distributed. Therefore, non-parametric methods were used to analyze this data (Chi-square and Phi methods). Statistical analysis methods were applied to compare between the students’ level in the morning shift and evening shift. When the data were collected for both shift from the physical education department in Duhok University. significant relation was found between all variables and Time-OF-Day except the year of study as there is no significant relation between Time-OF-Day and the year of study
The paper presents the results of the study examining morphological features of root system and their connection with herbage in different alfalfa genotypes, represented by the following varieties and populations: Louise, Zoryana, Nadezhda, Unitro, Seraphim, RK/98, PR-04, MO-115, SV, HMG. The study was conducted within 2015-2018 in the field conditions at the Institute of Irrigated Agriculture of NAAS at the dark-chestnut soil. The crop cultivation technology was standard for the irrigated conditions of the zone of the study conduction. The experimental data were processed by the generally accepted procedure of the analysis of variance and Pearson’s correlation analysis. The results of the study testify about the significant differences in root system morphology in different genotypes of alfalfa, and their unequal value for plant breeding work. The varieties Zoryana, Seraphim and the population MO-115 with a high volume of the root system of 6.9-7.0 milliliters and the established links between the studied features of subsurface and herbage biomass are recommended to be used in further alfalfa breeding work
Waste management is an important issue form Morocco. According to many possibilities, recycling construction and demolition wastes (CDW) as aggregates replacing naturel aggregate for concrete is a solution that deserves to be evaluated. In this study three sample of concrete are tested. 2 with different percentages of recycled aggregates Their properties are compared to the concrete with natural aggregates. Concrete is realized and tested in thermal conductivity (cylindrical 5x3.23 specimens). With quantity of recycled aggregates is (0 %, 10 %, 20 %) in different temperature (20°. 30°.40°.50°C). Numerical modeling with FORTRAN program was proposed for comparing between experimental and numerical results. It is shown that the use of recycled aggregate as replacement for natural aggregate in concrete decreases the thermal conductivity. we also see that the value of the thermal conductivity decrease with the increase of the temperature of the ambient air 20 degrees up to 50 degrees for the 3 samples Normal concrete and concrete with recycled aggregate. For the three samples the numerical and experimental results were in good agreement. The following conclusions can be drawn from this work: that according to the thermal properties, the recycled aggregate concrete possible to be used in the same applications as conventional concrete
This work concerns a mathematical modeling and a numerical simulation of the transesterification reaction of lipids extracted from micro-algae by biodiesel. We have developed a numerical model to simulate the consumption of reagents, the evolution of reaction intermediates and the formation of products. The model is based on the Euler and Runge-Kutta methods. The system of equation established from the different reactions that take place during the trans-esterification has been solved using a numerical code written in FORTRAN. The simulation gives the evolution of the relative concentrations of reactants, intermediates and products of the reaction as a function of time. The duration of reagent consumption and product formation reactions is shorter when equation resolution is done by the Runge-Kutta method. The results obtained by the latter are close to those of the literature
This article presents an experimental study of the characterization of local materials used in building construction. These materials are Adobe bricks and stabilized with lime. The objective of this experimental investigation is to study the effect of chemical stabilization of lime on the mechanical and thermal properties of adobe bricks. The added lime content is 0%, 4%, 7%, and 10% of the soil mass. The results of this study showed that the thermal conductivity decreases and depends considerably on the lime content. The results also show that the compressive resistors are increased as a function of the increase in the lime content up to 7% (optimum) and above this threshold a decrease of up to 10% is observed
