Speaking ability is one of the integral language components in English language acquisition. This ability is a challenging one to master for ESL learners as it involves several linguistic and non-linguistic features in presenting ideas and it is frequently associated with anxiety. Public speaking anxiety is a common issue faced by students learning a second language. Feelings such as stage frights and nervousness could contribute to their anxiety in communicating using the target language. Other than that, the classroom environment, among other factors such as instructor and peer pressure, could also pose as threats for students particularly in public speaking settings. The present study aims to investigate whether public speaking anxiety can be alleviated through the use of an online platform, video blogs. Creation of personal video blogs could potentially help learners by providing a safe and non-threatening learning environment in practising their public speaking skills. T.....

The World Health Organization (WHO) recommended Cerebral disorders treatment within 90 minutes of the first medical encounter. Where the specialist should recover blood flow to the brain rapidly by injecting intravenous drugs in emergency situations. Tele Encephalopathy Diagnosis includes the use of advanced communication technology to convey to the off-site neurologist the pre-hospital 21-lead EEG signal for early triage, which has been shown to minimize time and overall mortality dramatically. However, hospitals also find the implementation of EEG transmission technologies very difficult to implement. Seven major technological obstacles to pre-hospital EEG transmission are established in the project research, in particular, paramedical discomfort and transport delays; signal noise and processing errors; system failure and communication losses; cellular network reliability; non-compliance with digital EEG format requirements; poor communication with electronic medical records; and cos.....

The prediction of water level in floodplain area is important for early signals and flood control. A total of 6350 hourly water level time series data located at Sungai Dungun were used in this study. The data were divided into training set and testing set. The training set consisted of the first 6000 data which were used to predict the last 350 data. A total of six set data consisting of different amount of training set of data were involved in this study. Consequently, it was used to determine the influence of different amount of data on predicting accuracy by using chaos approach. Those sets of data required a combination of parameters for prediction. In this study, the different amount of data had impacts on the combination of parameter for prediction. In addition, the correlation coefficient showed different values for all sets of data and excellent prediction when they were all used in testing the data. Hence, the different total amount of data will give impact on different combi.....

The security of Internet of Things (IoT) devices has become a matter of great concern in recent years. The existence of security holes in the executable programs in the IoT devices has resulted in difficult to estimate security risks. For a long time, vulnerability detection is mainly completed by manual debugging and analysis, and the detection efficiency is low and the accuracy is difficult to guarantee. In this paper, the mainstream automated vulnerability analysis methods in recent years are studied, and a vulnerability detection algorithm based on symbol execution is presented. The detection algorithm is suitable for lightweight applications in small and medium-sized IoT devices. It realizes three functions: buffer overflow vulnerability detection, encryption reliability detection and protection state detection. The robustness of the detection algorithm was tested in the experiment, and the detection of overflow vulnerability program was completed within 2.75 seconds, and the dete.....

A new analytical method based on vortex-assisted liquid-liquid microextraction with back extraction (VALLME-BE) coupled with high performance liquid chromatography was developed for the simultaneous determination of antidiabetic drugs; repaglinide, glibenclamide, and glimepiride in water samples. Chromatographic separation was achieved using C18 column (250 ? 4.6 mm ? 5 �m) and methanol-phosphate buffer (pH3.7) in the ratio of 70:30 v/v as a mobile phase at a flow rate of 1 mLmin-1. VALLME-BE was performed using 200 ?L of n-octane dispersed into the aqueous sample (10 mL) with the aid of vortexing agitation. Then, the analytes were back-extracted from the organic solvent to 0.05 M NaOH (40 �L). Under these conditions, enrichment factor of 155-fold was achieved. The developed VALLME-BE method showed excellent linearity in the range of 30 to 1000 �gL-1 with limit of detection (LOD) of 0.41-1.66 �gL-1 and limit of quantification (LOQ) of 1.38-5.54. 41-1.66 �gL-1. VALLME-BE was a.....

The genus Pulicaria belongs to the Asteraceae family, consists of ca. 100 species with a di-stribution from Europe to North Africa and Asia, particularly around the Mediterranean. The Pulicaria essential oils were recognised to possess considerable biological activities with a varied chemical composition. This article aims to overview the medicinal uses, chemical compositions, and biological activities of Pulicaria essential oils considered as a medicinal plant, widely used as traditional herbal medicines in the treatment of various diseases. The data were collected from the scientific electronic databases including SciFinder, Sco-pus, Elsevier, PubMed, and Google Scholar. A total of sixteen Pulicaria species have been reported for their essential oils and biological activities. It can be observed that the major components were carvotanacetone, ?-pinene, 4-terpineol, ?-caryophyllene, and cis-chyr-santhenol. Pharmacological studies indicated that the essential oils exhibited antioxidant.....

Last year (2020) has been a challenging year for many sectors, including the education sector that was forced to adapt to new uncertainties. During the COVID-19 pandemic, students had to rely on their gadgets and the Internet for online learning. As a measure of cultivating technology in teaching English as a Second Language (ESL) during the global crisis, Video log (Vlog) was used as a learning tool among the undergraduate students of various disciplines. Vlog served as a medium for students to convey their ideas and experience as these students needed to record themselves in a video. They would actively spend time preparing materials and practicing speeches. This study uses secondary data collected in early 2021. Hence, it covers most of the data in COVID-affected 2020, especially since the Vlog assessment was implemented in September 2020 for the undergraduates who took the English Proficiency paper. The study aims at examining the use of Vlog as a speaking learning tool and the cha.....

Previous studies [Langmuir, 2014, 30, 21, 6057?6063, Phys. Chem. Chem. Phys., 2017,19, 23869?23877] have shown that surfactants bearing highly-methylated alkyl tails (so-called ?hedgehog? groups) are able to reduce the limiting surface tension at the aqueous critical micelle concentration (CMC) to ?CMC ~24 mN m?1, which is considerably lower than for common n-alkyl tail surfactants (30?40 mN m?1). In the quest to develop even more effective and efficient non-fluorinated surfactants, this study introduces new amphiphiles having double and triple hedgehog tails and examines relationships between surfactant structure and aqueous solution properties. Of particular interest are links between ?CMC, the effective hydrophobic-tail layer density (?layer) and total number of carbon and silicon atoms in the hydrophobic tails (NC+Si). Interestingly, ?CMC is seen to depend on ?layer rather than NC+Si, and ?layer ~0.63 g cm?3 appears to be an optimal surface layer density for promoting low ?CMC. For.....
