    Abstract: Sterilisation by heat can be a capital treatment for ballast water and waste heat from ship’s engines will be a good resource. Based on the waste heat availability on an operational tanker, a ballast water treatment system was envisaged including a shipboard heat exchanger for waste heat recovery. To verify the heat availability and the species’ mortalities, test rigs were arranged similar to shipboard arrangement. For assessing the smaller heat exchangers for the tests, designs were developed using Bell-Delaware approaches based on the shipboard heat exchanger design. The thermodynamic and geometric values were computed and the features of the commercially available and fitted heat exchangers were compared with the developed designs. Two commercially procured heat exchangers fitted on two separate engine test rigs were used for tests. The designs of commercially procured heat exchangers were close to the developed designs and were found to be suitable for the tests planned.

    Abstract: Aedes albopictus is one of the most invasive mosquitoes in the world that harbors and can transmit many arboviruses, most notably dengue and chikungunya virus. In recent time, Ae. aegypti has gained more attention during dengue outbreaks compared to its counter parts, obscuring the role of Ae. albopictus as a vector. Moreover, existing data regarding Ae. albopictus is also currently limited in Malaysia. Hence, the present study was conducted to determine the genetic diversity of Ae. albopictus using molecular techniques from two dengue infested areas in Subang Jaya, Selangor, namely Taman Bukit Kinrara (TBK) and PJS7. Cytochrome oxidase 1 (CO1) gene from field collected mosquitoes were analyzed and compared to the USM laboratory strain (F135) together with sequences from the GenBank. Results from this study revealed that the field collected mosquitoes from TBK and PJS7 are genetically similar with each other. However, the samples exhibited polymorphism with the laboratory strain by 47 variable nucleotide sites. Our local samples are related with the   Ae. albopictus populations from India, probably due to its migration across these two regions via several human activities. This study shows that the CO1 gene is a valuable marker for the detection of Ae. albopictus and can be utilized to study its worldwide geographical distribution. Further analysis is strongly recommended using larger sample size and different localities to validate and substantiate our findings.

    Abstract: Aluminum (Al) doped titanium dioxide thin film with different Al doping concentration (Al = 0 mol%, 1 mol%, 3 mol%, 5 mol% and 7 mol%) were deposited using solution spin coating technique and the effect of Al concentration on the structural, morphological and optical properties were examine. All samples were annealed at 450°C for 1 hour. XRD reveal that the films exhibits anatase crystal phase at (101) peak orientation. Based on the FESEM and AFM image it is found that, surface morphology of the film was significantly affected with different doping concentration. Al doped titanium dioxide with 3 mol% Al concentration shows the highest transmittance compared to others samples. Consequently, it is shown that different Al doping concentration plays vital roles in producing an optimum Al doped titanium dioxide thin films samples.

    Abstract: Fungsi universiti dalam mengkomersilisasikan patent telah banyak dikaji oleh penulis. Setengah universiti telah berjaya mengkomersilisasikan paten mereka terutamanya dengan melesenkan kepada syarikat gergasi atau pun dengan menubuhkan kompeni spin–off. Walau bagaimanapun masih terdapat sebahagian paten universiti yang tidak dieksploitasikan. Kajian ini membincangkan apakah karekteristik paten yang tidak dikomersilisasikan. Sebuah universiti di Scotland telah digunakan sebagai kajian kes. Sepuluh jenis patent yang tidak diekploitasikan oleh universiti berkenaan telah dipilih untuk kajian. Penyelidik daripada paten tersebut telah ditemuduga dengan mendalam menggunakan soalan semi berstruktur. Temuduga telah direkod, ditranskrib, dan data telah dianalisis berdasarkan kepada setiap kes dan silang kes berbantukan Nvivo software. Dapatan menunjukkan sebab yang paling penting kenapa paten tidak dieksploitasikan adalah berkait rapat dengan teknologi itu sendiri. Teknologi didapati berada pada tahap pembangunan yang terlalu awal. Ini menyebabkan syarikat yang telah kukuh lebih berhati–hati untuk membangun dan memasarkan teknologi tersebut. Walau bagaimanapun terdapat teknologi yang mempunyai potensi untuk dieksploitasikan jika peruntukan disediakan untuk penyelidikan lanjut. Dalam kes yang lain pula setengah teknologi telah dipintas oleh teknologi yang lebih ke hadapan dan teknologi tersebut telah mendahului pasaran. Kurangnya motivasi di kalangan penyelidik–penyelidik untuk melihat inovasi mereka ke pasaran, kurangnya jaringan dan pemasaran produk oleh penyelidik dan pihak TTO, adalah juga menyebabkan ia tidak diekploitasikan. Mengkaji kenapa universiti paten tidak dieksploitasikan akan meningkatkan pemahaman tentang proses pengkomersilan bagi paten di universiti. Hasil kajian dapat membantu dalam proses membuat keputusan untuk mengkomersilisasikan hasil penyelidikan universiti. Pemahamam mengenai karekteristik atau ciri universiti paten yang mempunyai potensi nilai ekonomi yang tinggi hanya patut dipatenkan, dan ini akan mengurangi bilangan paten yang tidak dieksploitasikan. Kata kunci: Paten yang tidak diekploitasikan, pengkomersilisasi; universiti paten The role of universities in commercialising their patents has been studied extensively. Some universities have succeeded in commercialising their patents especially through the route of licensing to established companies or forming new spin–off companies. However, there are some university patents remained unexploited, which represent wastage to the universities. This paper discusses what are the features of some patented technologies that are not commercialised. A case study of a university in Scotland was used in this study. Ten patents which are not being exploited by the University were selected. The inventors of these technologies were interviewed in depth, using semistructured questionnaires. The interviews were recorded, transcribed and the data was analysed based on a case and cross case aided by Nvivo software. The findings show that the most significant reason why patents are not exploited is associated with the technologies themselves. The technologies were found to be at very early stage of development, thus established companies were wary of taking them to market. Lack of motivation among the inventors to see their inventions being exploited, lack of industry networking and marketing of the TTO and inventor are another important reason that led to the inventions unexploited. Studying why some university patents were not exploited will enhance the understanding of the process of commercialisation of university patents, which would help refine the decision making process of patenting. Understanding the characteristics of the university inventions that have high economic potential thus should seek patent protections would reduce the number of unexploited patents. Key words: Unexploited patents; commercialisation and university patent

    Abstract: Green highway is a roadway planned and designed with desires to integrate transportation functionality and ecological. A green highway takes high consideration on the approach of environment to the transportation system development, the ecosystem, urban growth, public health and also to surrounding communities. Reference to standard system such Green Roads Rating System becomes more popular being used to measure the classification of a green highway. This journal paper aimed to discuss on how important is the energy efficiency criteria to be measured in the green highway development. Energy is considered highly related to highway development due to it is the most infrastructures involves in massive construction activities from its construction up to the operation and maintenance process. Relevant energy criteria in green highway development had been figured out and a checklist of the comparison among the current relevant reference in the green highway is highlighted in this paper. These identified criteria for energy efficiency are importance to be considered in Malaysian Highway Index. The criteria include the consideration on Energy Plan for Green performance strategies, energy plan for maintenance, grey and green compound and car park, rest and service area (RSA), toll plaza and interchange.

    Abstract: A renowned motorcycling instructor noted that human error is the main reason for motorcycling road tragedies. Indeed, there are various reasons that could be held responsible in leading towards human error. Even so, it is strongly emphasized that there is a link between motorcycle road accidents with the cases of human error due to motorcycling fatigue. The aim of this study was to explore the physical, physiological and psychological symptoms experienced by motorcyclists during prolonged motorcycling and its relation with motorcycling fatigue. This study assessed motorcycling fatigue generally, without specifying in a single type of fatigue resulting from prolonged motorcycling activity. Literature assessment, real world riding assessment, working posture hazard assessment and a survey study were selected as the research methods for this study. Results showed that collectively, all the physical, physiological and psychological aspects of the motorcyclist could be a variable in leading towards motorcycling fatigue. Nevertheless, all of these variables would only lead to two final outcomes which are: (i) overall decrement in motorcycling performance, and (ii) sleepiness. Both of these outcomes could occur independently or dependently – dependent on individual motorcyclist and the responsible variables that is affecting the particular motorcyclist. In short, motorcycling fatigue could not be simply defined with one single definition. Therefore, it is best to view motorcycling fatigue in various perspectives (physical, physiological and psychological perspectives) of motorcycle ergonomics. Motorcycling fatigue is almost inevitable, thus, further research is warranted in order to gain more accurate information and better understanding on motorcycling fatigue.

    Abstract: Vehicular discomforts are a type discomforts experienced by a human operator upon operating a vehicle. This type of discomfort could prevail both physically and physiologically. Generally, it could be said that vehicular discomfort is almost inevitable for all vehicles. Even so, from the preliminary studies, it was found that it is a norm for the Malaysian public to have a preconception that a motorcycle possessed a higher degree of vehicular discomfort that as oppose to a car. Hence, this study was made in order to test the validity of this cognitive linkage made by the public. The aim of this research was to quantify the magnitude of differences between the vehicular discomfort experienced between operating a motorcycle and a car. In addition, the sources of vehicular discomfort of these two modes of transportation were also identified. The methods used for this study were working posture assessment and survey studies (consisting of a questionnaire study and semi-structured interviews). From the selected research methodology, it was found that both types of vehicles showed an almost similar vehicular discomforts patterns. Even so, the sources of vehicular discomfort presented by these two types of vehicles are unique. By identifying the sources of vehicular discomfort given by these two types of vehicles, further ergonomics improvements could be implemented and more in depth research could be performed.

    Abstract: Stearic acid (SA) was used as an additive in the process of metal injection moulding (MIM). It was added to the wax/polymer mixture in order to modify the powder wetting, mould lubrication, mixture viscosity, residual stress and debinding behaviour. In this study, the effect of SA in feedstock formulation on mixing torque and rheological properties was investigated. Further, it’s correlation on the as-moulded and as-debound parts behaviour was also investigated. The results showed that addition of SA significantly reduced the mixing torque value and viscosity which correspond to decreasing in inter-particle friction. As a result, injection moulding could be carried out at a lower temperature to achieve sound moulded parts and increased the removal rate of binder during solvent extraction process. However, it seemed that increasing the SA had a little negative effect on the as-moulded density.

    Abstract: Graduate employability has become more rigid nowadays whereby industries demand not only for graduates’ academic qualifications but also their ability to communicate in English. However, there is hardly any exit test instrument available in higher learning institutions that could gauge the graduates’ communicative competence before graduation. Thus, to address this matter, the Test of English for Communication Skills (UTM-TECS) was developed aims to provide potential employers with a more accurate measure of graduates’ readiness to function in the workplace. Given that the demand of English in the workplace is continuously changing through time, it is therefore important to ensure the assessment scale used to assess graduates’ oral competency takes into account the latest and up-dated requirements and expectations sought by industries. Hence, this study was conducted to investigate the current criteria that the industries adopt in recruiting new graduates.  Besides that, the study also aims to compare the industries’ assessment criteria with the criteria used in the UTM-TECS scale. This study utilized interviews as the data collection method and eight Human Resource personnel from different firms in Johor Bahru and Kuala Lumpur were involved. The study reveals that academic degree is needed for screening purposes; i.e. to shortlist the potential employees. In addition to that, soft skills which comprise of communication skill especially the English language speaking skill, team work, attitude, professional image and critical thinking ability are amongst the criteria used to select graduates for employment. It was discovered that the criteria listed by the respondents were almost similar to the criteria found in the scale except for one criterion; attitude which is not present in the UTM-TECS assessment scale. The respondents also viewed professional image as the highest of importance as compared to the UTM-TECS assessment weightage. The findings from the study could be useful in re-validating the UTM-TECS oral interaction scale so as to ensure its quality and to improve it tobecome a better yardstick for graduates’ employability and marketability.

    Abstract: The importance of recreation cannot be overemphasised. Recreation refers to an activity that people engage in during their free time, and it is socially-inclined and has attendant values.  Inaccessibility to recreational areas affects the social wellbeing of residents, who will not have a sense of belonging when it comes to community development, hence a response to Covid-19.  Taking Greater Jos (Nigeria) as a case study, this paper assesses the social factors with regard to the provision of recreational facilities. The study also identified and mapped out recreational areas using the geographical positioning system. A questionnaire survey was conducted amongst the residents, age fifteen and above to authentically gauge their opinions on the study and, adopting stratified-random sampling considering the ten sectors according to the Greater Jos Master Plan. Results revealed that the residents had a good level of awareness of the presence of recreational facilities and high-quality recreational facilities, which were found mostly within the core of the city. The facilities fostered a high level of family and community bonding. However, the distance of recreational activity areas from their place of residence was what was rather disappointing for most people. Thus, the recent Covid-19 pandemic demand of social distancing negates social inclusion. The emphasis on social orientation and effective social inclusion of disadvantaged groups was conspicuously pronounced. Thus, appropriate and easy access to recreational facilities for all genders and ages must be provided closer to the people for effective services to promote their social lives and weaken the Covid-19 repulsive protocol.
