Ni_0.1Mn_0.4Cu_0.2Cd_0.3Fe₂O₄ has been planned to prepare by the sol-gel auto combustion procedure. From the frequency 20 Hz to the frequency 15 MHz, dielectric properties, electric modulus, impedance spectroscopy, and ac conductivity has been documented with the help of an impedance analyzer. From the graph of the real dielectric part, it has been viewed that the dielectric constant value reduces with the boost of frequency that can be elucidated through Maxwell and Wagner's two-layer theory. A lucid peak has been found in the graph of the imaginary electric modulus part that is the clear distinction between two conduction regions in the frequency area. In the impedance spectroscopy, high impedance has been monitored in the low-frequency section. Enhance of ac conductivity in the high-frequency section reveals the activity of grains over grain boundary.

Character education as a national culture in building student character. However, not all learning strategies can build student character. The purpose of this study is (1) to explain the learning strategies of Islamic religious education and manners in the cultivation of student character in SMK Negeri 2 Depok Sleman Yogyakarta, (2) describe the implementation of Islamic religious education and manners, learning strategies in the cultivation of student character in SMK Negeri 2 Depok Sleman Yogyakarta, (3) explains the results of the application of Islamic education and character education . This research is a qualitative research. This type of research is descriptive field research. The research method consists of observation, interviews, and documentation. Data analysis using data reduction, data presentation and conclusion drawing.

The results showed that (1) the strategies used were directed learning strategies, indirect learning strategies, interactive learning strategies, experiential learning strategies, and independent learning strategies, (2) the implementation of learning strategies of Islamic religious education and manners in instilling student character is done by selecting a number of strategies that have been adapted to the material to be delivered, then supported by using several learning methods in delivering learning material, (3) students try to run and apply in daily life through habituation and try to do the best.

Heat Release and Emission Analysis as an Indicator of Decreasing Cyclic Variation in Spark Ignition Engine Fueled by Gasoline Ethanol with Oxygenated Additive

As one component that may affect performance and emissions is that the cyclic variation if the cyclic variation is simply too large, the result's very influential on torque fluctuations which may reduce the engine driveability. This study examines the effect of gasoline bioethanol blends on a single-cylinder spark-ignition engine which is distributed by variations of fuels (E0, E5, E10, and E15) by adding 0.5 % vol/vol oxygenated cyclohexanol. The test results can improve COV_IMEP in the cycle to cycle variations so torque fluctuations are often minimized which ends in improved engine performance (heat release), besides that emissions become better.

Bangladesh faces various types of natural hazards from its birth due to geographical location and physiographic sitting. Flood is the most common event among them. North-eastern part of Bangladesh faces flash flood almost every year with large scale of damage. Tanguar Haor, a famous ramsar site of Bangladesh located in Sunamganj district. This wetland adjacent areas are the most vulnerable zone in terms of flash flood hazard. About more than 80% people are the direct victim of this hazard. This study tries to assess the risk and resilience status of flash flood using risk and resilience assessment matrix. To accomplish this research both primary and secondary data have used. Through this work the comparative view between risk and resilience status has tried to represent. That shows the actual penetration of the depth of risk reduction policy making to improve the condition and minimize the losses of flash flood in the study area.

An Evaluation of the Shelter Used to Accommodate Refugees at Buduburam Camp

Since the end of the Second World War (1939-1945), the number of refugees continues to increase worldwide due to political crisis, civil wars, and human rights violations. Reports by the United Nations High Commissioner for Refugees (UNHCR) indicate that the number of displaced people keeps escalating and that since 2015 the number surpasses 1% of the world’s population. This study conducted at the Buduburam Refugee Camp near Accra – Ghana, examined emergency shelters and the security situation at the camp in order to create prototype emergency shelters aimed at making secure and comfortable accommodation available to refugees in camps. Though the total number of refugees was 42,000, a sample of 300 respondents participated in the study. Structured questionnaire survey and observations were the tools employed for the study. The results of the study indicated that by architectural and international humanitarian standards, shelter, sanitary, and emergency conditions in the camp were very poor and required some level of improvement to make life comfortable, healthy and secure in the camp. However, per the views of majority of the respondents, life in the camp was generally secure, and that a good relationship existed between the refugees and the Ghanaian community. Notwithstanding, there was the need for improvement in the shelter, sanitary, and emergency facilities of the camp.
