Single-frequency sound wave delays tomato (solanum iycopersicum) ripening by suppressing respiration and regulates lycopene / Muhammad Afiq Azman
Full text linkTomato had become one most consumed and utilized fruit. Tomatoes are
cultivated, harvested and commercialized on a wide scale all over the world. This
poses the question ·'Would the tomatoes last long?" Fresh tomatoes place on a
counter would only last for a week and extended for another week if stored in
refrigerator at 23°C. The onset of senescence is triggered by ripening process.
Ripening process in tum triggered by multitude of factors. The major factor
known is the initiation of ethylene biosynthesis. The accumulation of ethylene
would trigger multiple enzymatic processes along with multiple protein synthesis.
The transition of chloroplasts into chromoplasts is driven by enzymatic action that
results in the loss of green coloration among tomatoes. Carotenoids on the other
hand are the main coloration pigments that give the orange and red coloration to
tomatoes. Single-frequency sound wave at 1 kHz as the treatment agent of the
project proved to have delays ripening process when applied to a group of
tomatoes. The results showed a noticeable different between controlled group and
treated group. The color transitions from green to red of the tomatoes were
considerably slower in treated group during the whole period of 15 days. The
sound wave treatment also reduces the respiration rate of tomatoes as the headspace
gas sample analyzed revealed that the amount of C02 was lower in the gas
sample of treated group. The GC test showed those treated groups only have
0.39886% C02 content out of 50 mL gas sample taken. In contrast, controlled
group's C02 content was 1.27148% with the same volume of gas sample. The result
obtained proved that single-frequency sound wave at I KHz was capable of delaying
ripening process as well as reducing respiration rate in tomatoe
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
A study on the factors influencing employee's motivation in Petronas Penapisan (Melaka) Sdn Bhd / Muhammad 'Izzat Ishak and Muhammad Afiq Ahlami Azman
Full text linkThe study aims to identify the factors influencing employee's motivation in PETRONAS Penapisan (Melaka) Sdn Bhd. It is very important for an organization to ensure that the employees are highly motivated. In this research, the researchers chooses four factors which are employee involvement, reward and recognition, job security and organizational culture. 100 respondents were chosen from the total population from five departments in the organization by using simple random sampling. These five departments are Human Resource Management and Administration, Finance, Legal and Corporate Affairs, Engineering and Health Safety Environment and Security department. The findings of the study are, all independent variables have significant relationship with employee's motivation. The researchers also found that employee involvement is the most significant predictor variable. Overall, the researchers able to answer all objectives
Marine debris monitoring and awareness program
No full textKuantan is the capital state of Pahang. Being the one of the most prominent cities of the east coast peninsular, it host many beaches that lay before the world’s important water namely the South China Sea. Due to its strategic geographical location, the Kuantan coastlines are also renowned spots for tourism and fishing activities.
However, their popularity consequentially leads to many irresponsible acts of littering and dumping of waste by humans at the beach. Besides that, the immense collection of marine debris along the coastline is influenced by several factors such as the dumping of disposal items by humans to the river and estuarine, insufficient space for landfill and other marine litters from fishing activities such as fishing nets, lines and rods.
According to Al-Jazeera News dated January 26, 2019, Malaysia is home for booming illegal plastic processing industry. It is said that developed countries such as the UK and New Zealand exported their plastic wastes to the country for recycling purpose.
It is also revealed that not all the plastics imported are recyclable. This has drawn the ministry to call a permanent ban on plastic wastes import and conduct a series of raiding operations to these unlicensed plastic waste recycles factories to reduce environmental harm due to the rapid development of landfill areas.
Another article by Science Magazine in 2015 stated that Malaysia was placed eighth worst country worldwide for plastic waste. The study reported that Malaysia produces approximately one million tonnes of improperly disposed plastic waste in 2010. Some of the wastes are leached and discharged to the ocean, killing marine animals and accumulated to form an “island” of garbage.
In response to this critical issue, IIUM collaborating with Institute of Oceanography and Maritime Studies (INOCEM) are proud to provide a platform for the residents to contribute to the environment by participating in a marine debris monitoring program at Cherok Paloh Beach, Kuantan.
As residents of premier Islamic research university, we acknowledge the importance of protecting and keeping our environment clean especially when the campus is situated just 30 minutes away from the coastal areas.
This serves as a good initiative to raise awareness among the residents in a sense of promoting environmentally concerned society through interactive environmental community service activity
