    The role of aerial dispersal in shaping patterns of biodiversity remains poorly understood, mainly due to a lack of coordinated efforts in gathering data at appropriate temporal and spatial scales. It has been long known that the rate of dispersal to an ecosystem can significantly influence ecosystem dynamics, and that aerial transport has been identified as an important source of biological input to remote locations. With the considerable effort devoted in recent decades to understanding atmospheric circulation in the south-polar region, a unique opportunity has emerged to investigate the atmospheric ecology of Antarctica, from regional to continental scales. This concept note identifies key questions in Antarctic microbial biogeography and the need for standardized sampling and analysis protocols to address such questions. A consortium of polar aerobiologists is established to bring together researchers with a common interest in the airborne dispersion of microbes and other propagules in the Antarctic, with opportunities for comparative studies in the Arctic.

    Non-destructive eddy current testing (ECT) is widely used to examine structural defects in ferromagnetic pipe in the oil and gas industry. Implementation of giant magnetoresistance (GMR) sensors as magnetic field sensors to detect the changes of magnetic field continuity have increased the sensitivity of eddy current techniques in detecting the material defect profile. However, not many researchers have described in detail the structure and issues of GMR sensors and their application in eddy current techniques for nondestructive testing. This paper will describe the implementation of GMR sensors in non-destructive testing eddy current testing. The first part of this paper will describe the structure and principles of GMR sensors. The second part outlines the principles and types of eddy current testing probe that have been studied and developed by previous researchers. The influence of various parameters on the GMR measurement and a factor affecting in eddy current testing will be described in detail in the third part of this paper. Finally, this paper will discuss the limitations of coil probe and compensation techniques that researchers have applied in eddy current testing probes. A comprehensive review of previous studies on the application of GMR sensors in non-destructive eddy current testing also be given at the end of this paper.

    Counting citations have been the usual norm to determine the impact of any research and/or scholar. However, with majority of the scholarly activities happening on the World Wide Web, traditional counting of citations is now being termed "slower." The recent explosion of online data storage for many articles may serve as a pool which uses social media sites to navigate. Altmetrics has been proposed as the new entity which aims to change the focus of the scholarly reward system to value and encourage web-native scholarship. This paper makes an attempt to understand altmetrics.

    This study was aimed at exploring the impact of religiosity on purchase intention towards counterfeit products by investigating the mediating role of consumer attitude. This study investigated religiosity as an independent variable, attitude towards counterfeit as a mediator while predicting the purchase intentions of the consumers. A self-administered questionnaire using a five-point Likert scale was used to collect data from the sample of 420 respondents who were from twin cities (Rawalpindi and Islamabad) of Pakistan. Structural equation modeling technique was used to achieve the set objectives. The results reveal a statistically significant effect of religiosity along with the significant mediating role of consumer attitude and the significant moderating role of hedonic benefits while predicting the purchase intentions of the consumers. This study also provides important insights for the researchers and the practitioners.

    This paper reports on the potential use of geopolymer in the drilling process, with respect to tool wear and surface roughness. The objectives of this research are to analyze the tool life of three different economy-grade drill bit uncoated; high-speed steel (HSS), HSS coated with TiN (HSS-TiN), and HSS-cobalt (HSS-Co) in the drilling of geopolymer and to investigate the effect of spindle speed towards the tool life and surface roughness. It was found that, based on the range of parameters set in this experiment, the spindle speed is directly proportional to the tool wear and inversely proportional to surface roughness. It was also observed that HSS-Co produced the lowest value of surface roughness compared to HSS-TiN and uncoated HSS and therefore is the most favorable tool to be used for drilling the material. For HSS, HSS coated with TiN, and HSS-Co, only the drilling with the spindle speed of 100 rpm was able to drill 15 holes without surpassing the maximum tool wear of 0.10 mm. HSS-Co exhibits the greatest tool life by showing the lowest value of flank wear and produce a better surface finish to the sample by a low value of surface roughness value (Ra). This finding explains that geopolymer is possible to be drilled, and therefore, ranges of cutting tools and parameters suggested can be a guideline for researchers and manufacturers to drill geopolymer for further applications.

    Many researchers studies have shown that stressful life events, from the death of a loved one to the loss of a job, are linked to an increase in certain health problems, particularly heart disease, diabetes, and hypertension. Many people assume that stress leads to cancer as well. Evidence for this, however, is not clear. However, the significance of mind-body interactions in medicine is now increasingly being recognised.(Copied from article.)

    The research mentorship programme is unique in that it is a planned journey undertaken by the mentor and mentee, preferably with well-defined milestones along the journey. During the journey, familiar landmarks will be pointed out by the mentor. In path-finding situations the experience and wisdom of the mentor and the critical appraisal of both mentor and mentee will contribute to learning from the encounter. In most mentor-mentee partnerships, a formal acceptance to the relationship, well-defined landmarks measuring progress in the journey, regular appraisal of the skills developed and acquired, and phased, judicious modification in the individual roles of that relationship will be required. Although there is no consensus on the elements of mentorship, there are some strategies which can contribute to the success of the relationship. Critical success factors include convergence of the research area within the broad expertise of the research mentor. The research mentor should have a proven research track record and is committed to serve in that official capacity. The research mentoring process is dynamic and characteristics of both mentor and mentee contribute to the robustness of that relationship. The mentee would have identified some attributes of the mentor that are desirable and is willing to work hard to achieve, build on, and improve upon. In the research setting endpoint measurements of success will be based on recognition of the research standing of the mentee, measurable outcomes such as number of papers in top tier journals, citation indices, etc. consultancies attracted as well as invitations to deliver plenaries in scientific conferences, patents filed and research findings translated and applied, and other measures of research productivity. In the pursuit of research excellence the mentee would have imbibed values of professionalism and ethics in research and would have constantly kept in mind that to be successful, the mentee would be able to excel beyond his mentor and that the next generation of researchers will seek mentorship from him.

    Precision farming offers numerous benefits and advantages to the farming community for farm productivity improvement. Previous research has led to the development of the offline-based recision Farmer©. Our current research extends further the previous work by developing a Web Paddy GIS©. The need for this arises due to limitations of Precision Farmer© such as portability, offline system accessibility and affordability by the end users, who include semi-literate farmers. This new system has been developed to function on Windows and Linux platforms. A user satisfaction assessment was conducted on website acceptability, and performance testing was made. This study demonstrates that Web Paddy GIS© can successfully run on both platforms. However, the Linux platform has proven to be superior to Windows, based on factors such as CPU usage, speed and user satisfaction. This paper presents a novel management tool of Web-based precision farming for the semi-literate paddy farming community of a developing country. The development of the Web Paddy GIS© is very useful for paddy farmers, farm managers, decision makers and researchers.

    This study examines the relationship between religiosity and level of happiness in an Islamic context among Muslim students studying at Malaysian universities. The determinants of happiness included in this research are positive attitudes, self-esteem, and other-esteem. Religiosity has long been considered as the main determinant in increasing happiness, and educational level strengthens its relationship. For this purpose, the researchers sampled 230 Muslim students aged 17-40 years studying at Malaysian universities in Kuala Lumpur, Malaysia. The study found a positive and significant correlation between religious commitment and level of happiness. Religious commitment also shows positive and significant correlations with positive attitudes, self-esteem, and other-esteem. The study also concludes that educational attainment moderates the relationship between religious commitment and happiness. Thus, religious commitment plays a very important role in increasing levels of happiness.

    Introduction: The New Zealand White (NZW) rabbit model is commonly used for the research of
    posterolateral intertransverse lumbar arthrodesis. The standard approach reported by many
    researchers are a muscle splitting approach through the intermuscular plane between multifidus and longissimus muscles. Methods: In this research the fusion bed was exposed by retracting the three groups of paraspinal muscles (multifidus, longissimus and iliocostalis) medially. Results: This alternative method showed good exposure of the transverse processes and intertransverse membrane with less bleeding from the muscles observed. No death due to surgical complication was observed out of twenty-four rabbits operated. Conclusion: An easy and safe method for performing posterolateral intertransverse lumbar arthrodesis was demonstrated and recommended as an alternative approach for surgery on New Zealand White rabbits.

    Microwave Remote sensing data have been widely used in land cover and land use classification. The objective of this research paper is to investigate the feasibility of the multi-polarized ALOS-PALSAR data for land cover mapping. This paper presents the methodology and preliminary result including data acquisitions, data processing and data analysis. Standard supervised classification techniques such as the maximum likelihood, minimum distance-to-mean, and parallelepiped were applied to the ALOS-PALSAR images in the land cover mapping analysis. The PALSAR data training areas were chosen based on the information obtained from
    optical satellite imagery. The best supervise classifier was selected based on the highest overall accuracy and
    kappa coefficient. This study indicated that the land cover of Butterworth, Malaysia can be mapped accurately
    using ALOS PALSAR data.

    The purpose of the present study is to provide a critical review on the revolution of the "compliance" concepts from compliance to adherence, and adherence to concordance for both pharmacological and non-pharmacological therapies. A comprehensive literature search was performed using online databases from Library of University Putra Malaysia, and Pub Med based on the keywords. The present study showed that both quantitative and qualitative studies cannot be neglected in assessing adherence and its related problems. One of major findings from the present review is that "compliance" was no longer suitable for current treatments and it is important to define concepts of the terms used (adherence or concordance) correctly and clearly. The findings reflected that researchers placed greater value on medication adherence than non-pharmacological adherence. There were three general factors related to treatments adherence, namely socio-economic factor, treatments-related factor and disease-related factor. The findings showed that both qualitative and quantitative studies found consistent results for most of the factors, except for the experience of diseases symptoms. Both study design contribute important values to the adherence studies and future studies should incorporate both quantitative and qualitative studies to understand adherence in both pharmacological and non-pharmacological treatments.

    Modelling observed meteorological elements can be useful. For instance, modelling rainfall has
    been an interest for many researchers. In a previous research, trend surface analysis was used and
    it was indicated that the residuals might spatially be correlated. When dealing with spatial data, any
    modelling technique should take spatial correlation into consideration. Hence, in this project, fitting
    of spatial regression models, with spatially correlated errors to the annual mean relative humidity
    observed in Peninsular Malaysia, is illustrated. The data used in this study comprised of the annual
    mean relative humidity for the year 2000-2004, observed at twenty principal meteorological stations
    distributed throughout Peninsular Malaysia. The modelling process was done using the S-plus
    Spatial Statistics Module. A total of twelve models were considered in this study and the selection
    of the model was based on the p-value. It was found that a possible appropriate model for the
    annual mean relative humidity should include an intercept and a term of the longitude as covariate,
    together with a conditional autoregressive error structure. The significance of the coefficient of the
    covariate and spatial parameter was established using the Likelihood Ratio Test. The usefulness
    of the proposed model is that it could be used to estimate the annual mean relative humidity at
    places where observations were not recorded and also for prediction. Some other potential models
    incorporating the latitude covariate have also been proposed as viable alternatives.

    PMID: 29750210 DOI: 10.1002/epi4.12033
    Objective: EpiNet was established to encourage epilepsy research. EpiNet is used for multicenter cohort studies and investigator-led trials. Physicians must be accredited to recruit patients into trials. Here, we describe the accreditation process for the EpiNet-First trials.

    Methods: Physicians with an interest in epilepsy were invited to assess 30 case scenarios to determine the following: whether patients have epilepsy; the nature of the seizures (generalized, focal); and the etiology. Information was presented in two steps for 23 cases. The EpiNet steering committee determined that 21 cases had epilepsy. The steering committee determined by consensus which responses were acceptable for each case. We chose a subset of 18 cases to accredit investigators for the EpiNet-First trials. We initially focused on 12 cases; to be accredited, investigators could not diagnose epilepsy in any case that the steering committee determined did not have epilepsy. If investigators were not accredited after assessing 12 cases, 6 further cases were considered. When assessing the 18 cases, investigators could be accredited if they diagnosed one of six nonepilepsy patients as having possible epilepsy but could make no other false-positive errors and could make only one error regarding seizure classification.

    Results: Between December 2013 and December 2014, 189 physicians assessed the 30 cases. Agreement with the steering committee regarding the diagnosis at step 1 ranged from 47% to 100%, and improved when information regarding tests was provided at step 2. One hundred five of the 189 physicians (55%) were accredited for the EpiNet-First trials. The kappa value for diagnosis of epilepsy across all 30 cases for accredited physicians was 0.70.

    Significance: We have established criteria for accrediting physicians using EpiNet. New investigators can be accredited by assessing 18 case scenarios. We encourage physicians with an interest in epilepsy to become EpiNet-accredited and to participate in these investigator-led clinical trials.

    The surrounding circumstances and environments of Malaysian older adults could make conducting interventions (mainly in terms of clinical or randomized controlled trials) a challenge. Working with older adults and facing cultural issues could be challenging.

    Objective: This paper illustrates a significant perspective of some of the challenges faced while conducting a randomized controlled trial exploring the impact of a multi-component intervention that included strategy- and process-based prospective memory (PM) training among Malaysian older adults.

    Methods: The current study was a randomized controlled trial (RCT) and therefore the challenges were presented in accordance with the CONSORT statement style.

    Results: A discussion on how these issues were addressed is provided.

    Conclusion: Some suggestions were presented to help researchers plan and create interventions for similar studies and to support a practical method of addressing all related challenges.
