Coarse aggregates derived from rock are commonly used as road pavement materials that meet the applicable specifications. This study uses rock aggregates originating from the polymeric area of Jayapura City, and this type is widely found in various areas of northern Papua. The study was conducted to determine the effect of local Papuan coral aggregates on the AC-WC Laston value. According to the 2018 General Specifications of Highways; namely, the added filler material must be dry and free from clumps and when tested by sieving according to SNI ASTM C136: 2012. The test results obtained characteristic values on the use of coral as follows: The highest density value at 4.5% asphalt content and the lowest 5.5% and 6.5%. The VMA value obtained is unstable, but all asphalt content meets Bina Marga Specifications 2010 Revision III, namely with a minimum VMA value of 15%, the highest VIM value of 3-5%, VFA values tend to increase but experience a decrease in asphalt content of 5.5% and 6.5%. The results of the Marshall test on coral material in the AC-WC layer are the high strength value 5495.89 kg, density: 1.74 gr/cm3, VMA: 24.42%, VIM: 15.83 %, VFA: 0.01%, flow: 10.00 mm, and MQ of 348.03 mm/kg. The value of Optimum Asphalt Content (KAO) used as AC-WC layer is 5.5%.

With the development of Internet of Vehicles, radio frequency identification technology (RFID) has been widely used in vehicle networks. The classic RFID authentication scheme cannot meet the special security and confidentiality requirements of RFID in Internet of Vehicles. This paper proposes an RFID authentication protocol in the Internet of Vehicles based on the certification center (CA). Through the certification center, you can avoid the Dos attack problem faced by the back-end server and reduce the server's computing burden. At the same time, through the authentication center, the identity authentication of the back-end server, reader and vehicle tag is indirectly achieved, which solves the problems of replay and malicious tracking that are often faced in RFID. The theory of formal logic language GNY proves that the protocol has high security in the Internet of Vehicles.

With the increasing labor quantity the profit may increase after a certain quantity, which means the deficit will be substituted by the benefit in forge process of hub. So that through turnover to be established the benefit may be formed after turn point. Detail value is needed to calculate the field according to the curves between them. The TC and AC is the first factor to consider and then AVC and AFC which is second factor. The profit point has one piece when labor is constant. That means that in the scope of this field the profit may be available. When the labor and capital inclines the total cost will incline. Average cost is no proportion to total cost. With increasing stress and diameter the force may increase.

With the increasing diameter and stress the power applied to motor wheel may increase in proportional, which means the big power will be formed in forge process of motor. Furthermore with increasing height and rotation it may increase as well. So that through power equation to be established the properties may be designed and checked before made. Detail value is needed to calculate the hub power according to the curves between them. The stress of hub is the first factor to consider and then its diameter and height which is second factor. The bigger power is 12KW and 35KW when rotation is 10r/m and height is from 350mm to 150mm respectively. That means that in the scope of this field the power may be bigger enough. When continuing to incline height the power will no change. The time increases as diameter and height inclines. The time will incline as the rotation declines.

Original Research Article Objective: The mnhB gene of Halobacillus Y5 was cloned to clarify its basic biological information. Methods: The genome of Halobacillus Y5 was extracted and the gene fragments were obtained by PCR, then 400~900 bp fragments were recovered and linked to vector pUC18. The constructed recombinant plasmids were transformed to competent E.coli KNabc by functional complementation, and the strain containing the gene of Na + /H + antiporters was screened for bioinformatics analysis. The positive monoclonal strains were screened by specific medium. Results: mnhB gene has two CDS regions, respectively 305 bp and 128 bp, encoding 96 amino acids. The predicted relative molecular weight is 11048.16 Dt, the isoelectric point is 4.66, the fat coefficient is 130.40, and the instability coefficient is 29.15. It is a stable protein with a half-life of 30 h. Comparison of similarity between mnhB from Halobacillus Y5 and 5 sequences, the homology of wp_101843976.1, wp_082234107.1, wp_079529991.1, wp_128522668.1, wp_08502981.1 were 93%, 69%, 78%, 69%, 67%, respectively. Through phylogenetic tree analysis, the Na + /H + antiporters from Halobacillus Y5 is in a separate branch, which may be a new member of Na + /H + antiporter. Na + (Li + , K)/H + antiport activity was detected from everted membrane vesicles prepared from E. coli /pUCmnhB but not those of /pUC18. Conclusion: A new mnhB gene was successfully cloned, which laid a theoretical foundation for the development and utilization of Halobacillus Y5.

Shells, probably like no other product of nature, have played an important role in the history of mankind. The pre-Hispanic civilizations of Ibero-America also used certain type of shells profusely in their religious ceremonies, in particular, in Ecuador there were two species of main importance, the Spondylus princeps and the Spondylus calcifer broadly employed to manufacture ornaments that possess a strong symbolic, religious and social meaning and that were almost exclusively used by ruling classes. Among these ornaments, the faces carved on the Spondylus shells are little known. In the present study, we chose a total of fifteen (15) pieces from the Pastor Restrepo Lince´s archaeomalacology collection to understand the possible uses of these objects, through the interpretation of the gestures represented on the faces, their dimensions, and their geographical distribution in pre-Hispanic Ecuador. To achieve the proposed objective, we approach the present investigation from the perspective of the formal analysis of concepts, which is a mathematical theory of representation of knowledge, finding that these faces carved in Spondylus, were used daily or in special ceremonial occasions and that its use was common in all the regional cultures of ancient Ecuador, from the oldest such as Valdivia, and for more than 2000 years, indicating a long tradition of the use of Spondylus as an object of great symbolic and economic value until the arrival of the Spanish

Original Research Article Good performance of any construction project refers to continuous improvement of the project activities to achieve the project objectives. This research has been designed to study the construction performances of Hospital for Advanced Medicine and Surgery (HAMS) building construction project based on quality control and safety. The quality of construction was studied by comparing the quality control test results with the standard values. The construction safety provision of HAMS project was studied through a questionnaire survey. The responses from a questionnaire survey and review of records from concerned representative were examined to identify the factor affecting the performance of building construction. The factor affecting the performance was identified and presented in various ways for the interpretation. Materials were found to be of good quality when compared with the standards, even though only 41.9% of cube moulds were of required strength as per the compressive strength results. It was due to lack of curing and poor workmanship. All the 45 labors were selected for the questionnaires for construction safety provision of the construction site. All the labors have faced minor accidents which required only first aid. Helmets, gloves, boots, safety belts and safety glasses were provided as personal protective equipment which was proper and suitable. There were no documents for the safety at site. The hygiene condition of site was good but no labors were aware about safety precautions and safety procedures at site. Nondestructive and rebar locator test for the structure were not performed though 58.1% of cube moulds were failed in their compressive strength test, so nondestructive test must be performed with expert consultation and required steps must be forwarded before operation of hospital. Effective and efficient training courses for engineers in quality, safety, productivity, information systems and management of human resources must be conducted. Consultants should be more interested about the quality of the project. Awareness programs for labors towards possible risks and hazards in a construction site can improve safety situation so awareness programs must be conducted regularly at site. The study has not covered time and cost aspects.

Nondestructive and rebar locator test for the structure were not performed though 58.1% of cube moulds were failed in their compressive strength test, so nondestructive test must be performed with expert consultation and required steps must be forwarded before operation of hospital. Effective and efficient training courses for engineers in quality, safety, productivity, information systems and management of human resources must be conducted. Consultants should be more interested about the quality of the project. Awareness programs for labors towards possible risks and hazards in a construction site can improve safety situation so awareness programs must be conducted regularly at site. The study has not covered time and cost aspects.","PeriodicalId":379926,"journal":{"name":"Scholars Journal of Engineering and Technology","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116557528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
