Waste materials (e.g. rock wool, glass wool, walnut shell and MDF powder) determined at the rate of 10% of the polymer matrix weight were replaced with polymer. Unit volume weight, ultrasound transmission velocity and thermal conductivity values of the produced composite materials were examined. In the experiments, it was determined that the thermal conductivity value of the walnut shell reinforced sample was higher than the control sample. It was determined that the thermal conductivity value of the MDF powder reinforced composite was slightly lower than the control sample. The rock wool and glass wool-reinforced composites partial collapse was observed. Thermal conductivity value is higher than the control sample.","PeriodicalId":13986,"journal":{"name":"International Journal of Engineering Research and","volume":"63 1","pages":"310-320"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87948068","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}

The designed system produces three kinds of alarms (Buzzer, bi-color LED, and SMS) with a security breach notification through an LCD, based on the data from its interfaced sensors (Motion Sensor, Fire Sensor, and Glass-break Sensor). The microcontroller used to control all aspects of the system is Atmega8. A Light Depended Resistor (LDR) and a Potentiometer (POT) are used to build the Motion Sensor; Temperature Detector LM35 is used as the Fire Sensor; and a sensitive metal strip is used to build a custom Glass-break Sensor. SIM900 (GSM) is used to design an SMS generating system as one of the alarming methods. The designed system is found to be consumed very low power with a 5V supply since when it is ON, the bi-color LED (0.1watt) requires only 0.98μA and 23.5mA of current, and 4.88mW and 117.5mW of power during its state change; and the Buzzer consumes only 0.49mW of power when it is ON. The system is designed with the consideration of incorporating a double-grid power management system, and a dedicated Sun-tracking solar power system is designed to increase its overall efficiency and sustainability. The whole system is designed and verified using ‘Proteus 7.7 Professional’ and the core part of the system is physically constructed and tested. The programming of the Atmega8 is done using ‘Code Vision AVR version 2.5 Professional’.","PeriodicalId":13986,"journal":{"name":"International Journal of Engineering Research and","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84134472","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}

A lack of political commitment and weak institutional capacity among transportation sector leadership exacerbates this urban predicament. In these contexts, this paper examines the efficiency of the 2012 transport sector reform package initiated by Addis Ababa City Administration under mayor Diriba Kuma. Through this research, the roles played by (a lack of) political commitment and institutional capacity in the design, management and implementation the urban reform agenda are closely examined. To do so, the paper utilizes a Public Sector Governance (PSG) reform framework to analyze the interplay between political commitment to reform and institutional capacity to implement agreed reforms. In particular, the paper highlights the outcome of reforms in circumstances in which there is substantial political commitment but low institutional capacity. In this regard, to achieve better public policy outcomes the study identifes the need for dismantling unnecessary bureaucratic procedures as well as addressing inefficiencies in governing structures, coupled with revisiting and improving existing norms, rules and regulations in transport governance. a policy reform plan focused on five pillars which aimed to narrow the gap between policy and implementation; a) development of strategic plans and standards that sustainably augment the current and future transport challenges of the City; b) institutional capacity building; c) project coordination and integration among different stakeholders and within the bureau; d) creating a system of sustainable operation of transport systems and services of the City; e) infrastructure development. The necessity of the reform was also to address some complex political and social contests including corruption, patronage, and political capture according to the General Manager of AARTB (reference?).","PeriodicalId":13986,"journal":{"name":"International Journal of Engineering Research and","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82267968","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}

Arsenic is a metalloid that is known for its toxicity and carcinogenicity. Arsenic causes arsenicosis and several carcinogenic diseases and other diseases. The high arsenic concentration in groundwater in the country is believed to be due to the over-exploitation of groundwater for irrigation purpose and domestic water supply, inadequate recharge of the aquifer and lack of water management in Bangladesh. Several tube-wells in Bangladesh have been found to contain arsenic in concentration that is beyond the permissible limit which is 0.05 mg/l (50 µg/L). Up to 75 million people in Bangladesh are at risk of arsenic exposure. Arsenic affects crops and the food chain and can result to poor yield of crops. Some advanced technologies can also be leveraged to mitigate arsenic contamination. The government of Bangladesh has played a significant role in minimizing or eliminating arsenic contamination but it is not capable enough to deal with the problem. Remediation methods can be resorted to but most important would be to close down wells that have a concentration of arsenic beyond the permissible limit.","PeriodicalId":13986,"journal":{"name":"International Journal of Engineering Research and","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84642944","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}
