Natural resource consumption and high energy costs occur during the production of insulation materials made of mineral wools (e.g. rock wool, glass wool). Alternative insulation products are needed to reduce the consumption of natural resources. In this scope, composite materials with polyester resin were produced by using mineral wool (rock wool, glass wool), which is a waste, walnut shell, which is agricultural waste, and MDF powder, which is industrial waste. 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.

58 Abstract—To address the safety of the home or other facility, a microcontroller-based solar-powered anti-theft automated security system is developed with arrays of sensors to detect possible intrusion incidents. 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’.
摘要为了解决家庭或其他设施的安全问题，开发了一种基于微控制器的太阳能防盗自动安全系统，该系统具有传感器阵列，可以检测可能的入侵事件。设计的系统根据其接口传感器(运动传感器、火灾传感器、玻璃破碎传感器)的数据，通过LCD发出三种警报(蜂鸣器、双色LED、短信)和安全漏洞通知。用于控制系统各个方面的微控制器是Atmega8。光相关电阻(LDR)和电位器(POT)用于构建运动传感器;温度探测器LM35作为火灾传感器;并使用敏感金属条来构建定制的玻璃破碎传感器。采用GSM (SIM900)协议设计了短信生成系统，作为报警方式之一。在5V电源的情况下，系统功耗非常低，双色LED (0.1w)在开启时只需要0.98μA和23.5mA的电流，而在状态变化过程中只需要4.88mW和117.5mW的功率;蜂鸣器开启时的功耗仅为0.49mW。该系统的设计考虑了纳入双电网电力管理系统，并设计了专用的太阳跟踪太阳能发电系统，以提高其整体效率和可持续性。整个系统使用“Proteus 7.7 Professional”进行设计和验证，并对系统的核心部分进行了物理构建和测试。Atmega8的编程是使用“Code Vision AVR version 2.5 Professional”完成的。

The longevity of imported used vehicle determines urban outdoor air pollution and affects government’s regulatory policy measures to balance the benefit of used vehicle usage and its negative externalities. This paper estimates the life expectancy of vehicles in Ethiopia for a maximum of 30 years. The study used four different models to determine the total vehicle stock, survival rate and scrap rate of vehicles at different age and the total emission respectively. The models support different estimation, where there is difficulty to find actual data related to scrap vehicles. The total emission calculation serves policy makers to make a learned and informed decision that improves urban air quality.

:- Following rapid urbanization, Ethiopia’s capital city Addis Ababa has become circumscribed by a complex set of multi-pronged transport challenges that are a greatly contributing to its overall urban inefficiency. 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?).

This paper critically reviewed the prevailing socioeconomic trends in the Niger-Delta, Nigeria and concludes consequences of socio-economical disequilibrium, public health and environmental issues due to oil spillage. Niger Delta is a densely populated region in the sub-Saharan Africa and described as the engine room that drives economic growth and development in Nigeria as up to 80% of the Nigerian economic growth stems from this region. This region bears on the nation’s economy but development is skewed to its disfavor owing to the public policies that are frequently in disfavor of the people. Multinational oil companies explored fossil fuel blandly and thereby curtailed the sustainability of the environment. On the hand, Nigerian government has taken some remarkable steps and employed different methods to mitigate spillages. Contrarily, studies indicate the failure of the law and weakness of the government to enforce the law catalyzed by corruption.

— The number of Leadership in Energy and Environmental Design (LEED) projects in Egypt has increased since 2010. This paper aims to reveal the ambiguity about attributes, trends, and levels of achievements in these projects by conducting a statistical analysis of the LEED-awarded projects. The descriptive statistics clarified that most awarded/registered projects have applied for building design and construction certification (LEED 2009-NCv3). The author merged both dot-plot and boxplot techniques to visualize and measure the achieved points in the seven categories of the mentioned version. For inferential statistics, the effect size was measured between possible and scored points in both categories and credits using the nonparametric Cliff's δ effect size test. The statistical analysis shows that: Regional Priority category had a small Cliff's δ effect size (0.3), with almost half of its credits achieved high scores. Water efficiency and Innovation in design categories had a large Cliff's δ effect size (0.7), but 1/2 and 2/3 of their credits (respectively) achieved high scores. Sustainable Sites, Energy and Atmosphere, Materials & Resources, and Indoor Environmental Quality had the maximum Cliff's δ effect size (1), with half (or more) of their credits achieved low-high scores.

- This paper delineates the impacts of arsenic on human and ecological health and subsequent treatments of arsenic related diseases in Bangladesh. 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.
