    De’Aroma is a company which is focusing on selling a natural scented candle. It all started when the owner of this company felt like most of the scented candle in Malaysia is expensive and so he decided to make his own. At first he do it for fun and after he give some of it to his family and friends, they encourage him to sell it online. It all started in early of March 2021 in Port Klang. The objective of the company is to create a scented candle that can be use in any occasion. The target market for this product is for teenagers and woman and it is only RM35 each. The tagline for this company is “The smell of happiness.” The mission of this company is Be you natural candle making of your choice that produce high quality of ingredient of scented candle that will inspire your sense with wonderful aroma. While some of the vision is in the short term, we aims to become one of the best scented candle making company in the country. De’Aroma use Facebook as a platform to run the business and it is a huge opportunity to post all of the product either as a Teaser, Hard Sell and Soft Sell. It is a great platform to expand the business and the best part is it is free to use. So we can cut a lot of cost for it. Lastly, we are hoping that De’Aroma will be a successful company in the future

    Melastoma decemfidum is an important medicinal plant as it contains the anticancer compounds kaempferol and naringenin. As traditional propagation via stem cutting has its limitations and is time consuming, micropropagation by tissue culture technique can be considered as an alternative method to cultivate the plant. This research aims to optimize in vitro micropropagation of M.decemfidum for its rapid mass propagation and continuous supply. In this study, an efficient protocol that utilised BAP and NAA individually and in combination was studied. About 1 cm of nodal explants of in vitro plantlets of M. decemfidum were cultured onto 25 treatments MS media supplemented with various combinations of BAP and NAA hormones (0.1, 0.2, 0.25, 0.3 mg/L). The highest mean number of shoots at 9.67 ± 0.33 and shoot length at 0.61 ± 0.03 cm were obtained from the nodal explant cultured on 0.30 mg/L BAP. The highest number of leaves at 23.83 ± 0.47 and roots at 4.33 ± 0.33 were recorded for the nodal explant in the MS media containing 0.25 mg/L BAP and 0.1 mg/L BAP in combination with 0.2 mg/L NAA. The experiment also revealed that the combination of BAP and NAA hormones encourages callus formation (indirect regeneration). Then, the best treatment was used to study the effects of different culture systems on M. decemfidum’s growth rate. The second research involved the micropropagation of in vitro plantlets of M. decemfidum via different culture systems such as agar gelled cultures (AGCS), permanent immersion culture system (PICS) and temporary immersion bioreactor culture system (TIBS). Under TIBS, in vitro plantlets were temporary immersed in liquid nutrient medium. The use of TIBS showed many quantitative benefits, most notably recording the highest proliferation rate in comparison with both solid and liquid culture systems. As mentioned, in vitro plantlets cultured in temporary immersion bioreactor (TIBS) recorded the highest growth rate with significance differences (p<0.05) in terms of shoot multiplication (4.62 ± 0.39), shoot length (0.34 ± 0.03) cm and leaf number (10.67 ± 0.54) compared to PICS and AGCS. Therefore, it can be said that in this study, the in vitro propagation of M. decemfidum was successfully optimized using TIBS. Considering the importance of detection of secondary metabolites in medicinal plants, Total Phenolic Content (TPC) was evaluated at different growth conditions. From the results obtained, the highest TPC reading of 25.32 ± 1.06 mg/g was for the TPC of ex vitro leaves, followed by in vivo (23.00 ± 1.60 mg/g), in vitro leaves cultured from TIBS (9.70 ± 0.34 mg/g), in vitro leaves from PICS (8.24 ± 0.34 mg/g) and in vitro leaves from AGCS (7.46 ± 0.24 mg/g). ANOVA analysis conducted showed that there is significance difference (p<0.05) between the TPC results of five samples. The highest TPC result showed that the ex vitro of M. decemfidum obtained using the acclimatization from plant tissue culture technique contains high contents of phenolic compounds which can be considered a good source of secondary metabolites

    This project demonstrates the hydrodynamic state of a stationary vehicle submerged in a moving water channel. Recent study uses the Wind Tunnel machine in order to find the lift and drag forces. However, a Circulating Water Channel can also be used. The concepts are quite similar but the CWC machine uses the concept of fluid dynamics. The objectives of this study are to determine the flow pattern of fully submerged model of sports car, ambulance, a jeep in different water velocity that is fully submerged underwater and to analyse the effect of lift and drag force on different vehicle models on flow pattern that formed. The experiments will be carried out using the Circulating Water Channel machine (CWC) under four Submerged Ratio (SR) conditions, such as the height of the pitot tube from the bottom, suggesting that the water pressure and flow velocity varied. A Digital Single-Lens Reflect (DSLR) Camera will be used to capture of flow pattern of water during around the vehicle models during the experiment. Then, in order to compare the three objects, the difference in pressure and flow results will be observed. The influence of flow pattern on three vehicles models are investigated. Then the drag and lift force will be calculated it is expected that a better aerodynamic shape will result to a better lift and drag forces

    The Doctoral Research Abstracts: enhancement of systematic sampling for clinical survey: systematic sampling with consecutive approach / Mohamad Adam Haji Bujang

    Full text link
    Survey is a one of the common primary data collection approaches in research in various fields including the clinical field. Findings from clinical surveys are important because recommendations from the findings will have a direct impact towards public’s health. Data collection process in clinical survey usually involves an ordered sampling frame and has become very challenging for clinical researchers, who need to handle multiple tasks in their clinical service whereby the clinical service is their top priority. Therefore, due to time constraints, the general practice of data collection in clinical survey is to adopt non-probability sampling such as consecutive sampling. The consequence of this kind of practice would produce results that can be invalid since the results could be influenced by sampling bias. In order to reduce sampling bias and to obtain more precise results is to promote the use of probability sampling technique in a clinical survey

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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
