This study aims to compare the antioxidant and antimicrobial activity of different parts (tip, mid and base portion) of lemongrass leaves for application as a natural ingredient in the functional drink.

Lemongrass leaf powder was prepared from different parts of leaves and evaluated for nutritional composition. Additionally, the extracts of different portions of lemongrass leaves were analyzed for total phenolics, free radical scavenging activities, ferric reducing antioxidant potential (FRAP) and antimicrobial activities for their application in food products.

Tip portion of lemongrass leaf anticipated significantly (p < 0.05) higher contents of ash, protein, calcium, potassium and iron i.e. 6.2 mg/100 g, 18 mg/100 g, 340 ppm, 819 ppm and 32 ppm, respectively. Maximum (p < 0.05) phenolics (14.7 mg GAE/100 g), 2,2-diphenyl-1-picryl-hydroxyl (86.3%) and FRAP (200 mmol/100 g) were observed in lemongrass leaf tip methanolic extracts. Moreover, lemongrass leaf tip hydro-methanolic extracts portrayed maximum zone of inhibition against E. coli and Staphylococcus aureus i.e. 16.7 and 18.2 mm, respectively.

This study demonstrated higher antimicrobial and antioxidant activities of the tip of lemongrass leaves as compared with mid and base portions, hence suggesting its role in the improvement of physicochemical, antimicrobial and antioxidant properties of food products. Consequently, the application of lemongrass methanolic extract up to 10% remarkably enhanced the nutritional value and sensorial acceptance of the beverages.

The present research draws evidence from laboratory analysis of fresh lemongrass grown in Pakistan. The findings suggest that lemongrass methanolic extracts could be used as a nutritionally rich source of antioxidant activity in functional drinks.

This paper aims to present the capacitance characterization of tapered dielectrophoresis (DEP) microelectrodes as micro-electro-mechanical system sensor and actuator device. The application of DEP-on-a-chip (DOC) can be used to evaluate and correlate the capacitive sensing measurement at an actual position and end station of liquid suspended targeted particles by DEP force actuator manipulation.

The capability of both, sensing and manipulation was analysed based on capacitance changes corresponding to the particle positioning and stationing of the targeted particles at regions of interest. The mechanisms of DEP sensor and actuator, designed in DOC applications were energized by electric field of tapered DEP microelectrodes. The actual DEP forces behaviour has been also studied via quantitative analysis of capacitance measurement value and its correlation with qualitative analysis of positioning and stationing of targeted particles.

The significance of the present work is the ability of using tapered DEP microelectrodes in a closed mode system to simultaneously sense and vary the magnitude of manipulation.

The integration of DOC platform for contactless electrical-driven with selective detection and rapid manipulation can provide better efficiency in in situ selective biosensors or bio-detection and rapid bio-manipulation for DOC diagnostic and prognostic devices.

Corrosion of fresh water systems are studied. Immersion tests under flowing water conditions were performed for periods upto 7 days. Pipe materials selected for this study included commercial alloys commonly used in fresh water systems such as mild steel. At the end of the long term experiment the materials exposed to the water flow were investigated using the SEM technique. The results showed that the morphology of the surface was dependent on the corrosion behaviour during experimentation. Heat treatment plays an important role in material stability in contact with flowing water.

Applying three psychological theories, this study aims to attempt to investigate the role of consumer psychology, specifically the factors of trust in vaccination, threat severity, fear, anxiety, risk and hygiene, and safety, on intention to resume hotel consumption. The authors also tested the mediation effect of anxiety among psychological constructs: perceived threat, fear and risk with the intention to resume hotel consumption.

Using purposive sampling, data were collected from 470 respondents from four cities in Malaysia and analysed by applying analysis of moment structures (AMOS) structural equation model technique. The respondents for this study were frequent travellers meaning the leisure tourists who at least travel twice a year or travel when getting the occasion to explore new things. In this study, an online survey was employed to ensure easy accessibility and to enhance the number of replies.

The results of this study confirmed that perceived severity, risk and fear influence travellers' anxiety. This study further confirms that trust in vaccination and hygiene & safety provided by the hotelier reduces anxiety levels. Anxiety is found one of the most important predictors of intention to resume hotel consumption, which further mediates the relationship between other psychological variables: perceived severity, risk, fear and intention to resume hotel consumption. Anxiety mediates the relationship between perceived severity, fear and intention to resume hotel consumption and partially mediates the association between risk and intention to resume hotel consumption.

This study examined three psychological theories and extended them by including the trust in vaccination and the hygiene and safety constructs. Anxiety was investigated as a mediator.

The main value in a culture of tolerance is wasatiyyah. The fragility of relationships and misunderstanding between Muslim and non-Muslim communities occurs when attention to values of tolerance which need more attention on moderation was not practiced especially in the life of a new Muslim convert community. Thus, the practice of moderation is one mechanism proposed by the government to ensure a harmonious continuation of life in a religious community can be achieved. For that, a qualitative study design was used to describe the current status of a phenomenon that occurs among new Muslim converts. The purposive sampling method is used to determine the applications of wasatiyyah in new Muslims’ life tolerance at Kota Kinabalu (East Malaysia) and Kuala Terengganu (West Malaysia). Although the study was conducted at two different locations, there is a relationship between religious phenomena that occur in the new Muslims community in Malaysia. The purpose of this study is to see the practical concept of moderation in the life of new Muslims and their relation with Muslims and non-Muslims. The results showed that the value of moderation was applied in the aspect of tolerance. The application of Wasatiyyah in practice of tolerance had helped non-Muslims family members to change their attitudes and perception towards Islam. This study suggests the values of wasatiyyah in the life of religious tolerance, need to be nourished especially in multiethnic society when sharing a living places, education and employment for better social development as well as a well-being pluralistic society.

The study was conducted through descriptive data qualitative methods. Purposive sampling was used which refers to a group that has the characteristics of samples required by researchers (Mohd Najib Abdul Ghafar 2003). This study applies the method of in-depth interview with the selected new Muslims around Kota Kinabalu (representing East Malaysia) and around Kuala Terengganu (representing Peninsular Malaysia/West Malaysia). Thus, data accumulation involves new Muslims (new Converts) from various ethnics (Sabahan and Sarawakian) which comprise Kadazandusun, Murut, Rungus, Sino and Iban. Secondly, those are from the Peninsular Malaysia which includes Chinese and Indian. Whereas in Kuala Terengganu, data accumulation involves new Muslims from various ethnics (Chinese, Indian, Sarawakian and others). The result of the interview is shown through descriptive narratives which display the practice of tolerance in the form of supportive interaction from the non-Muslim families towards the new Muslims in Islamic lifestyle.

The concept of wasatiyyah has nurturing tolerance among Muslim, newly Muslim and non-Muslim as well as fostering harmony among the diverse ethnics in Malaysia. Based on the discussion, it was observed that the concept of wasatiyyah had a great influence on the relationship among Muslim, newly Muslim and non-Muslim, as it had a strong link with the value of akhlaq that have been embedded in the Muslim community. The wasatiyyah is the main element that shapes the relationship, and it is the results of interaction with social norms, for it has bred certain social values that include tolerance, compromise, modesty, respect and cooperation as transpired when they (Muslim and newly Muslim) interact among themselves or with other communities. Furthermore, the main goal for the concept is to maintain peace and built well-being in the society as well as bracing racial ties in Malaysia, especially among Muslim, newly Muslim and non-Muslim.

Tolerance is a culture that founded the co-existence of pluralistic society in Malaysia. The culture of tolerance can only be built if ethnic tolerance and religious tolerance is accepted as a common practice – Muslims and non-Muslims alike. The description of wasatiyyah in the practice of religious tolerance among the families of new Muslims is the platform towards the acculturation of tolerance in the societal life from different faith and ethnics. It can be said that the higher the tolerance of ethnic, the higher is the religious tolerance, which is manifested through the application of wasatiyyah between people from different religions. This situation is highlighted in the relations of Muslim, newly Muslim and non-Muslim in Sabah and Terengganu where the culture of tolerance is apparent in the life together. Extensive interaction through encounters, acquaintance and co-existence that shape the friendship, brotherhood and kinship is the best formula in nurturing the culture of tolerance in the pluralistic society of Malaysia. Perhaps, the concept of wasatiyyah may be implemented in the whole aspect of life in the context of Malaysia. It is because the term wasatiyyah has the main sources of Islamic epistemology as well as sustaining the well-being pluralistic society without destroying the differences.

The study aims to investigate the students' perceptions on the teaching of Islamic education in the Malaysian secondary schools. The study will also look into the students' attitudes based on their personal self-evaluation as well as to examine the relationship between these two variables.

The study employs quantitative and survey research design. The instrument used for data collection was a questionnaire which is distributed to samples that were randomly selected in representing the selected population among students of Malaysian secondary schools. The instrument used is a modification of instrument developed by Ab Halim et al., Ahmad Munawar and dan Azhar. The pilot study done shows a high reliability of 0.924 for the assessment of Islamic education teachings and 0.869 for the aspect of Islamic attitudes. 3,262 Form 4 and 6 students from selected schools in Malaysia participated in the study. The data were analyzed to display the frequency, percentage, mean, standard deviation and Pearson's correlation.

The study revealed a high level of mean on the aspect of students' evaluation on the teaching of Islamic education at their schools. It was also found that the level of students' attitudes was also high, i.e. 4.26. There was a significant relation between the students' perceptions on the teaching of Islamic education and their attitudes (r=0.740, p=0.000).

The implementation of teaching and learning strategies and new approaches are some of important elements in the teaching and learning process of Islamic education. This study shows that the lesson of Islamic education has significant and strong relationship with the students' attitudes in their daily lives. Since the students felt that the lesson of Islamic education was important for them, teachers should improve the lesson on Islamic education by using different types of teaching methods, technique application and motivational approaches. The teaching of Islamic education should not only focus on theoretical aspects but must also emphasize on practical implementation of Islamic knowledge.

This paper describes the religious teaching and learning in schools which has significant relationship with the students' daily attitudes. A new area of research can be conducted to explore the most important factors of teaching and learning that contribute to the students' attitudes development. These findings can also be used by educators to improve the quality of the lessons based on the students' evaluation.

This paper aims to examine mobile banking adoption in Islamic banks by integrating technology adoption model (TAM) and Religiosity-Behavioural Intention Model.

This study uses a sample of 300 mobile banking customers of Islamic banks from West Java Province, Indonesia. Partial least square was applied to assess the association between perceived usefulness, perceived ease-of-use, religiosity, satisfaction, and adoption.

The results of this study disclosed that the integration of TAM and Religiosity-Intention model provides a more complete explanation of Islamic bank consumers’ adoption of mobile banking. Besides perceived usefulness and perceived ease-of-use, the results of this study emphasise the importance of religiosity in mobile banking adoption.

This study offers an opportunity for Islamic bank managers to increase the adoption of their mobile banking services. To increase the adoption of mobile banking services, Islamic banks must not only provide an application that is useful and easy to use but also consider the customer’s religiosity. All of their mobile banking marketing strategies should focus on providing high-quality mobile service while ensuring the bank’s operations are compliant with the Islamic law.

This study is the first attempt to integrate TAM and Religiosity-Intention Model to assess mobile banking adoption.

Despite the inclusion of entrepreneurship education (EE) in the curricula of tertiary education institutions in Nigeria, graduate unemployment is still an issue of serious concern. This calls into question the effectiveness of EE in influencing students’ entrepreneurial intentions (EIs) and behaviours. Perhaps, the issue is with the EE lecturers. The questions, which should be answered include: are the lecturers who teach EE entrepreneurially inclined? Can lecturers who are not entrepreneurially inclined teach students to become entrepreneurs? The purpose of this paper, therefore, is to empirically explore the role of entrepreneurial lecturers in the relationship between EE and students’ EIs.

This study adopted a quantitative approach. Thus, a self-reported questionnaire was administered to a randomly selected sample of 256 Higher National Diploma II students of the Federal Polytechnic, Idah, Nigeria, who were exposed to EE. To analyse the data collected, partial least squares structural equation modelling (PLS-SEM) was performed using SmartPLS 2.0.M3 software.

Data analysis showed a significantly positive relationship between EE and students’ EIs on the one hand and between EE and perceived entrepreneurial lecturers (PELs) on the other hand. It was also found that PELs had a significantly positive link with students’ EIs. Further analysis indicated that PELs had a mediating effect on the relationship between EE and students’ EIs.

This study was a single institutional study. Thus, the generalisability of its findings to other institutions is limited. Extending the research to other institutions and countries might be required to validate the findings presented.

This research work has some insightful implications for the teaching of EE. By implication, it provides an answer to the question: who should teach EE? To achieve greater impact of EE on students’ EIs and behaviours, entrepreneurial lecturers are required. It implies that EE lecturers should be entrepreneurially inclined. They should demonstrate sufficient entrepreneurial attitudes, intentions and behaviours.

It has been argued that graduate unemployment constitutes a social problem to the society. In this regard, the suggestions made in this paper, if applied, would help resolve the problem of graduate unemployment in Nigeria and other countries.

This study is the first to provide empirical evidence of the role of entrepreneurial lecturers in the relationship between EE and students’ EIs. It has demonstrated that entrepreneurial lecturers could transfer the influence of EE to students’ EIs. Also, it has confirmed that EE lecturers are critical in the EE-students’ EIs relationship. Overall, this study makes a significant contribution to the discussion on how to enhance the effectiveness of EE in influencing students’ EIs and behaviours.

This study aims to investigate the swelling behavior, mechanical and thermal properties of ternary rubber blend composites prepared by melt blending based on carbon black (CB)-filled natural rubber (NR)/styrene-butadiene rubber (SBR)/nitrile butadiene rubber (NBR) blends, containing a variety of compatibilizers. Various compatibilizers, maleic acid anhydride (MAH), prepared emulsion and adhesion system (HRH) were used. A series of NR/SBR/NBR blends at a 30/30/40 blend ratio reinforced with 45 phr of CB were prepared using the master-batch method.

Thermal aging properties of the composites characterized by their aging coefficient and retention in tensile and elongation at break (E.B. %). Thermal degradation of ternary rubber blend composites based on melt blending has been studied using thermogravimetric analysis.

The swelling coefficient decreased with increased compatibilizer loading. Results also showed that the tensile strength and E.B. (%) decreased with aging over the entire aging period. Additionally, the addition of compatibilizers into the ternary rubber blend composite had slightly improved the thermal stability.

Interactions between the different components of blends at the interfaces have a high impact on the interfacial properties of the rubber blend.

Compatibilizers significantly improve the properties of the resulting composites with the loading of investigated compatibilizers because of the uniform dispersion of CB in the rubber matrix.

Using blends in the rubber industry led to the high-efficiency production of low-cost products.

The rubber blending has a significant positive effect on a wide range of applications such as structural applications, aerospace, military, packaging, tires and biomedical, so improving the compatibility of blends will make new materials suitable for new applications.
