Bio colourant from algae with chemical solvent methanol using TLC method / Muhammad Zaim Haqimy Ramli
No full textAlgae are a chlorophyll bearing autotrophic thalloid plant body which mostly are aquatic plant. Moreover, the plant body of algae are unicellular to multicellular structure. To explain further, this study is about the pigments contained within the algae could be used as alternatives ways to replace synthetic colourant. We have identified, two types of algae which can be used in our research, which are macroalgae and microalgae. The colour pigments of the algae known for their vibrant colours, such as phycobiliproteins, chlorophylls, and carotenoids. The bio colourant was produced on a small scale, as to just see the colour pigments extraction using chemical solvent of methanol. The separation of the colour pigments from algae was performed by using the Thin Layer Chromatography (TLC) method. We collected 2 sample with same amount of weight for each total, with each one of the samples using different method of colour pigment extraction process of the microalgae. There are homogenizer and boiling method used to extract the colour pigment from the algae. The chemical solvent chosen were methanol, acetone, petroleum ether, and diethyl ether for the used in separation process. The methanol was chosen to extract the pigment using the two methods. After the extraction, we conduct the TLC method inside the glass chamber with ratio of chemical solvent mixture for separation process of the colour pigments. By then, the colour length from separation were used to calculate each of the retention factor (Rf) value to observe which one of the methods of extraction yield a better outcome. Moreover, the result will be compared to the extraction of raw algae, which is macroalgae with the same chemical

This study is also a method of understanding and reviewing related journal subjects and papers cited by this research found on our website. In addition, in this respect, the efforts and research expressed by the authors are very beneficial. Therefore, a lot of information about this research is available by understanding and referencing their research journals. The building condition assessment (BCA) is important to occupant that have want to stay at new house. It is because it will give the effect to occupant if get a house that have a lot of defects. Other than that, it will difficult if get a developer that does not take some responsibility with the house. This study will give occupant some knowledge to know the important of building condition assessment (BCA) and the benefit of Building Condition Assessment (BCA) to house. Every institution has a substantial physical asset in the form of a building. A building serves three basic roles linked to space: it offers protection from the elements, as well as safety and privacy to its users or occupants. Buildings deteriorated during their useful lives. (Douglas, 1996) evaluates the role of structures that have deteriorated over time, with the level of needed performance by consumers increasing with time to restore the quality and function of deteriorated structures, maintenance is necessary. In an effective and efficient manner Building maintenance will produce the best outcomes in terms of both quality and cost
Hak-hak tetamu dalam Islam: Kajian terhadap kemudahan hotel mesra muslim terpilih / Syed Muhammad Zaim Syed Mohd Zaki
No full textMinat masyarakat terhadap pelancongan Islam telah meningkatkan pendapatan sektor ini.
Malaysia telah menarik pelancong melalui pakej pelancongan Islam, dengan menawarkan
pelbagai aspek penginapan, terutama yang berkaitan dengan kemudahan mesra Muslim
untuk memenuhi hak-hak tetamu. Namun, dikatakan bahawa kemudahan yang disediakan
oleh pengusaha hotel mesra Muslim masih belum memuaskan dalam menunaikan hak
tetamu. Oleh itu, kajian ini dilakukan untuk melihat kemudahan yang terdapat di enam
hotel mesra Muslim terpilih yang dimiliki oleh Majlis Agama Islam Negeri dan untuk
mengesahkan usaha hotel dalam memenuhi hak tetamu. Proses pengumpulan data
menggabungkan kaedah pemerhatian dan temu bual. Hasil kajian menunjukkan bahawa
tahap ketersediaan kemudahan berdasarkan hak tetamu di hotel mesra Muslim adalah
memuaskan dengan ketersediaan melebihi 70%. Di samping itu, hasil kajian juga
mendapati bahawa hotel-hotel tersebut telah memenuhi hampir semua hak-hak tetamu
seperti yang digariskan dalam Islam. Walau bagaimanapun, masih terdapat beberapa
ruang penambahbaikan yang harus dipertimbang untuk mengukuhkan amalan sedia ada
demi keselesaan tetamu pada masa hadapan
Integration of bow tie analysis and ALOHA software for risk and consequences evaluation for heat exchanger in production of acetic acid during chemical process development and design / Muhammad Zaim Zulhilmi Zamri
Full text linkThe top priority of the industry in the current days is the safety and health of the chemical plant. This to ensure the workers could work without any worries and ease the civilian nearby. Despite this effort which has been so much time into there still an accident that related to heat exchanger in the chemical industry plant. Some of them were cause by loss of containment that lead to heat exchanger rupture and cause an explosion. The purpose of this study is to analyse the risk that presence in the heat exchanger for the production of acetic acid in the preliminary stage and do risk analysis using bow tie analysis and ALOHA modelling software and create risk mitigation. Risk analysis using bow tie only provide risk assessment without consequences analysis in detail thus using ALOHA modelling software to show the threat zone of the consequences in diagram. Analysing the result of ALOHA modelling software the most dangerous chemical that could cause the largest area of highest level hazard is the acetic acid with the red threat zone which the highest level of hazard raging around 700 meters. Implementing both bow-tie analysis and ALOHA in the preliminary stage could provide more detail and sophisticated risk analysis and create a prevention method to lowered the chance for the risk to occur
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
