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.

Concrete construction process faces a lot of problems seeking them continuously can raise the efficiency of construction process and concrete members. One of the major problems which occurred in concrete structure projects is the movement of the wood mold during construction, the concrete member may deform and case a deterioration of other surrounding structural members. This study investigates one of the critical problems in the building of Al-Masbah Telecom Center Company in Iraq. The twisting of the upper ends of the columns 25 mm was occurred while the lower end remains fixed, this rotation was achieved due to the movement of the wooden mold during construction process. This certain problem required re-analysis and extensive study to take a decision regarding the adequacy of column capability to carry applied load and redistribution of stresses in all structural members. The structural calculations revealed that there was no effect due to end twisting on column capability to carry the applied loads and structure stability. This study focuses on repairing one of a telecommunications concrete buildings in Baghdad (capital of Iraq); the damage in building was carried out due to twisting of columns as a result of movement in the mold during construction. This study includes an illustration of the damage causes and repairing methods. It is also includes a theoretical calculations of capacity of these columns after damage occurrence, and comparing the results with capacity of undamaged columns. This study also dealing with a reanalysis of the structure carrying capacity for applied loads
Aloe vera is considered as member of the Liliaceae family and Aloe Chinensis Baker is one of the species that is widely cultivated in Pontianak, Indonesia. The quality parameters of Aloe vera juice include pH, refractive index, vitamin C and density. The objectives of this study to investigate the influence of Sodium benzoate-Citric acid on the quality of Aloe vera gel juice, including pH, density, refractive index and vitamin C, as well to determine the storage time by using the Arrhenius approach. This study used 3 L of Aloe vera gel juice added with 1.8 g of Sodium benzoate and 6 g of Citric acid, stirred until homogenous then divided into bottles of 200 mL each for analyzing pH, refractive index, density, and vitamin C contents at the storage temperature of 30oC, 40oC and 50oC with the storage time of 0, 10, 20, 30, 40, 50 and 70 days. The determination of Aloe vera gel juice storage time was calculated using linear regression equation of the parameter with the lowest amount of activation energy. The obtained equation to determine the storage time was Ln k = -1233.1(1/T) – 0.8438 with the total activation energy of vitamin C is 2450.1697 cal/mol
