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.

The magnesium and magnesium alloys demand in several industries currently in Viet Nam becomes increasingly huge. The domestic consumption has promoted the development in researching the magnesium regional. In the world, the magnesium generating procedures are commonly known as Dow, Mintek, Magnetherm, Pidgeon. Among them Pidgeon tends to be the most popular one because of the convenience in the practical field, less requirement in the high quality workforce and low expenses. There is no factory in Viet Nam producing the magnesium, however, the diversity raw materials like magnesite and dolomite are strong foundation for Viet Nam to be independent in making magnesium. This study focuses on rating the magnesium producing process from dolomite ore in Thanh Hoa – Vietnam by Pidgeon while Chinese ferrosilicon is used as reducing agent. The crucial factors have impact on the recovering procedure including the reductant rate, recovering temperature, recovering period. The chemical and mineralogical analyse of Thanh Hoa dolomite has indicated that this kind of mineral is suitable for silicon thermal process to produce magnesium. The rate of calcium oxide and magnesium oxide after heating are 0.37, 0.54, respectively. A computing model using FacSage software has been applied to estimate the ability of magnesium recovery from Thanh Hoa dolomite. The result has predicted that recovery efficiency and the magnesium purity is extremely high. However, the result form the vacuum furnace in a range of temperature from 1000oC to 1300oC is lower than the one in the model. The test resultant has indicated when the rate of ferrosilicon go up 0.2 to 0.3 comparing to dolomite, the highest process productivity will be 0.84 getting with the volume of ferrosilicon 0.3.
As in the study on the conventional host, we investigated the effect of the dialyzable fraction isolated from Bifidobacterium longum whey on germ-free C3H/He mice mucus. Cow’s milk was, either, fermented with Bifidobacterium longum strain (F) or acidified by a 3M acetic – 2M lactic acid solution (C). Wheys F and C were dialysed against water. Each dialyzate was lyophilized and solubilized into water before sterilization by filtration. Germ-free (20) mice were maintained into isolator and fed with a standard diet. Ten animal received ad-libitum the F solution, the remaining ones the C solution. The mucus was then analysed. The chromatographic and electrophoretic analysis, as well as the variations of the Wesley ratio and the sum of the four sugars characteristic of the mucins, show that the dialysate F increases the proportion of native mucin, therefore a better protection. In addition, a different protein and glycoprotein composition and an increase in total protein and carbohydrate levels are observed in the fecal extract concentrate. It may be thought that there is a change in the catabolism of mucins, which leads to molecules of molecular weight greater than 10 KDa. However, the Dialyzate F not alter the cellular activity of the host
Hot mixture asphalt was applied in the erection of different types of flexible pavement for the most of highways in the world. With the development of industries and the prosperity of the world’s economic situation and the increase in trade movement and increasing traffic loads on highways, the flexible pavement surface suffered from structural problems then the pavement will suffer from failures. Therefore, there is needing to improve the hot mixture asphalt to resist the heavy traffic loads and environmental conditions. The objective of this study is to evaluate and improve the properties of hot mixture asphalt by using date palm fibers powder as additive material by application of some experimental works and theoretical calculations. The results showed that the using of date palm fibers powder will help to decrease the percentage of different types of voids in hot mixture asphalt and improve the density of mixture. The stability results were increased when using the date palm fibers powder comparing with normal hot mixture asphalt. Also flow values were improved.
Software Defined Networking (SDN) is the progressed communication systems administration structure that isolates the system information plane from the control plane. It has been seen as an energetic, layered, measured and strong technique to managing and controlling frameworks going from wired, establishment based farther networks to wireless networks. This type mechanism will also provide new services to improve network architecture. Major work in this paper has concentrated on the SDN usage in conventional and wired and wireless-based systems. The design of Wireless systems has ended up amazingly heterogeneous. Since of the decentralized nature of versatile ad-hoc wireless systems, node portability and resource limitations, secure as well as agreeable operation of versatile remote ad-hoc systems show vital challenges. Latest software-defined networking advancements shed new light on how an ad-hoc network can be controlled and overseen. Given the broad arrangement and availability of heterogeneous wireless networks, the control and administration of mobile ad-hoc systems with the modern software-defined organizing concept offer more prominent adaptability and conceivable outcomes to address certainty and security issues and permit unused characteristics and administrations
In the present research, an attempt had been made to utilize durian shell as a carbon source for catalyst support in transesterification of palm oil (PO). The objective of this research was to explore durian shell as a carbon source for catalyst support, its modification with KOH, as well as its characterization and application in transesterification of PO. Prior to usage, durian shell was calcined at 600℃ for 2 h in a furnace. Carbon formed was impregnated in KOH solution, followed by drying and calcination. The resulting activated carbon was characterized by SEM-EDX, FTIR, and BET. The activated carbon was then utilized as a solid catalyst in biodiesel formation. Transesterification was conducted at 55 to 70℃, methanol to PO molar ratio (MPR) of 12:1, catalyst load of 2-5%, and reaction time of 90-150 min. The highest biodiesel yield of 97.3% was reached using 3% catalyst load at 60℃ for 90 min. Biodiesel obtained in this work was then characterized for its chemical physical properties. The biodiesel properties met the European standard (EN-14214). The results suggested that durian shell based activated carbon is applicable as a solid catalyst for biodiesel synthesis
