Study on combustion characteristics of different compositions of LPG
No full textVarieties of liquefied petroleum gas (LPG) are based on variety composition of propane and butane. The common composition of LPG contains 70% or 60% volume of butane and 30% or 40% volume of propane. However there have some variations of LPG composition as dictated by its usages and applications. Because of the different composition between propane and butane in LPG that used today, it can give different combustion characteristics of the LPG. The objective of this work is to study and analyze the combustion characteristic for different composition of LPG. The scope of this work is to analyze the energy that released which is commonly known as calorific value (CV), to determine the flame speed and to analyze the emission for different composition of LPG. The results get from this research are the calorific value of LPG that contains more butane is higher than one contains more propane. Beside that, the emission from LPG combustion is increased with the number of hydrocarbon in the LPG composition. Finally, the flame speed is decreasing when the composition of hydrocarbon is higher; in other word it decreases when LPG is contains more butane. The LPG that contains higher number of hydrocarbon can give more quantity heat by its combustion but the flame speed from it combustion slower and it also gives a higher effect to environment. The variation of composition in LPG gives an effect to their combustion characteristics. The research of combustion characteristic can optimize if using the sample of LPG that contain the other composition. Beside that, the other combustion characteristic like flammability limit also can be added to see the view of safety aspect when using the different composition of the LPG

Professor Sa’adiya Omar, the most celebrated author of women in the Sokoto Caliphate of Northern Nigeria. Professor Sa’adiya currently occupies the position of Nana Asma’u and Modibbo Kilo, the leaders of the Yantaru movement, i.e. Uwartaru (the Mother of the Yantaru). Equally, she had served as the National Amirah (President) of the largest Muslim umbrella organization in Nigeria – Federation of Muslim Women’s Associations in Nigeria (FOMWAN). As at the present, she serves in many capacities and is a member of various Islamic committees in Sokoto state and in Nigeria in general
STUDI PEMIKIRAN MUSTAFA AKYOL DAN HASHIM KAMALI TERHADAP PENERAPAN SANKSI APOSTASI: ANALISIS HERMENEUTIKA NEGOSIATIF
No full textThe death penalty for people who left from Islam is contrary to religious freedom. Human rights, which is the dominant discourse today, calls for a re-reading of the death penalty. The implication, there are many scholars who re-think the punishment of apostasy. Among them are Mustafa Akyol and Hashim Kamali who goes into this line. If the first name lives in the middle of a society where Muslims are a minority (America), then it is different from the last name. Hashim Kamali disseminated his ideas in Malaysia, one of the countries adhering to classical Islamic traditions. The fundamental question in this study is how the sanctions of apostasy are discussed again by the two thinkers.
This type of research is qualitative with future data on a library study (library research). These research data are derived from the representative works of Mustafa Akyol and Hashim Kamali on the subject of apostasy. Furthermore, the findings of their thinking are studied through the framework of negotiative hermeneutic theory. This theory was initiated by Khaled Abou El Fadl who pointed to the negotiations between the three entities, the author, the text and the reader. There are three key variables in discussing the thinking of Mustafa Akyol and Hashim Kamali. From texts and authority, the discourse of authoritarianism to the anatomy of the discourses of authority. Based on that, the approach taken here is socio-legal.
The first conclusion both Mustafa Akyol and Hashim Kamali have rejected the death penalty for apostasy. Second conclusion is using three variables when being analyzed by negotiative hermeneutic. In text and authority is able to be seen how a text is formed and its relationship with the social reality that surrounds it. The differences between the public who became the audience of them necessitate the differences in steps in the re-reading of this topic. On the discourse of authoritarianism can be reviewed the formation of non-authoritarian law by placing it as an entity that is constantly changing. Besides meeting the five prerequisites set by the hermeneutics of negotiations. In the anatomy of authoritarian discourse, there are three things that are discussed: consistency, a selective attitude to signs to the balance of interests and rationality. These two thinkers consistently use their respective steps in this topic. While Mustafa Akyol is selective to the sign, unlike Hashim Kamali. Despite this, they met at the same point with the conclusion that there is no death penalty for apostate perpetrators. This discussion is based on the success of both merging the importance of preserving religion and protecting human rights
A review on the effectiveness of change management in organization / Robeahtul Nabihah Anamallah and Nurhidayah Hashim.
No full textIn dealing with information is the crucial task in organization which can lead to the information leaking or wrong information. The process in sharing the knowledge during the transformation of work management also important because the change management are build a new and more effective work performance. Hence, change management is important for all organization. In the literature review study, the author highlighted the change management in organization which change leadership, the communication, and employee engagement and employee commitment. The literature review is significant to individual, organization, policy makers and knowledge worker

A comparative study of cascade h-bridge multilevel voltage source inverter and parallel inductor multilevel current source inverter
No full textThis paper presents the analysis study between multilevel inverters that are often classified into multilevel voltage source and multilevel current source inverters. For multilevel voltage source inverter (MVSI), the specific topology studied for this work is the Cascaded H-Bridge MVSI. Whereas, the multilevel current source inverter (MCSI) is based on Paralleled Inductor Configuration MCSI. For this study, the analysis between these converters are done with respect to the number of components, the advantages and disadvantages of each converters during performing inverter operation. In term of output voltage and current quality, the percentage of the Total Harmonic Distortion (THD) are measured and compared for both topologies. MATLAB/Simulink software has been used in this research to design and simulate in order to study the performances of both inverters

No full textI have been made aware of that fact that substantial parts of our paper published in Molecules [1] duplicate the contents of another paper previously published under our names in African Journal of Pure and Applied Chemistry [2] of which existence I was unaware. Although the compounds reported in both papers are different, I was not aware of the same biological data being used in the earlier publication. The article in Molecules was submitted in good faith based on the collective work that was presented to me by our co-author Dr Mughrabi, listed as the corresponding author of the article published in African Journal of Pure and Applied Chemistry [2]
