Stability of spray-dried microencapsulated anthocyanins extracted from culinary banana bract

ABSTRACT Culinary banana bracts are a potential source of anthocyanin, which can be widely used in the food industry because of its health beneficial effects. The aim of the present study was to study the stability of microencapsulated anthocyanin extracted from culinary banana bracts using ultrasound-assisted extraction (UAE). Central composite design (CCD) was used to optimize the process variables for the extraction of anthocyanin and the optimum condition was observed at 15:0.5 solvent to solute ratio, 53.97 ml/100 ml ethanol concentration, and 49.4°C. The optimized experimental anthocyanin content was 56.98 mg/100g and it closely agreed with the predicted value (57.29 mg/100g). High-performance liquid chromatography (HPLC) results revealed that cyanidin-3-O-glucoside and peonidin-3-O-glucoside were two constituents of anthocyanin. Encapsulated pigment powder exhibited satisfactory properties in terms of hygroscopicity, solubility, and good encapsulation efficiency with smooth spherical morphology (2–10µm) as confirmed by Scanning Electron Microscope (SEM). The storage stability of microencapsulated anthocyanin did not change noticeably up to 7 days but thereafter gradually decreased at 30°C and 75% relative humidity. During 21 days of storage, anthocyanin stability decreased by 44 %along with the decline in free radical scavenging activity.

Development of selenization/sulfurization-free CuIn(S,Se)2 for thin film solar cells applications

To meet the growing demand for energy and to reduce the depletion of fossil resources, technology for the harnessing of renewable energy is urgently needed. Among all the renewable energies, solar energy is one of the most clean, abundant and sustainable energy sources that can help to solve the world energy consumption problem. Harvesting and conversion of solar energy to electrical energy required the use of solar cells. Of all the different solar cell technology, copper-indium-gallium sulfide/selenide (CIGS) solar cell is one of the most promising thin film solar cells because of its high optical absorption coefficient, suitable band gap for harvesting a wide range of visible light from the sun as well as some unique electrical and optical properties. Compared to conventional vacuum-based synthesis, there is strong push towards the use of solution-based methods to prepare these CIGS films so that the processing cost can be reduced significantly. In this thesis, the solution-based synthesis of CuIn(S,Se)2 thin films as well as crystals and their application in the solar energy harvesting will be presented. Generally, for the solution-based synthesis routes, selenization/sulfurization process is usually needed to incorporate Se/S, to increase the crystallinity and to encourage grain growth. However, selenization/sulfurization is toxic and requires special processing system to cater for safety. Therefore this thesis sets out to investigate methods to synthesized absorber films without any selenization/sulfurization process and also ways to increase grains size.
Static vs Time-Varying Beta of Fama-French Five Factors Model in Indonesia and Thailand

This paper empirically investigates the various approaches to model time-varying systematic risk in Indonesia and Thailand by using time-series data from 2009 to 2017. Indonesia and Thailand were used as examples because of their growing economics since the turn of 20th century. As recent empirical studies have been conducted on stock markets in developed countries, there is an increasing need for testing in emerging markets, which have grown and become increasingly popular with international investors, such as Indonesia and Thailand. This study examines dynamic beta models using GARCH (1,1), EGARCH, TARCH, Schwert-Seguin, and the Kalman-Filter group to empirically find the most optimal time-varying beta model. This study uses the Fama-French Five Factors asset pricing model to include other factors that might influences value of systematic risk for each portfolio in both countries. This model can capture five factors that can affect returns, namely market factors (CAPM), size, book to market equity, profitability, and investment. By incorporating volatility and state space estimation, this study compares all tested models based on information criteria (AIC, SIC, and HIC). The results of this research proves that GARCH (1,1) in Indonesia and TARCH in Thailand outperforms other models in capturing the systematic risk. This study will be useful for future economic studies in Indonesia, Thailand and their neighboring countries.

Does higher population matter for labour market? Evidence from rapid migration in Canada

Abstract Canada has been a host country to migrants for decades through its attractive immigration policy. To enrich the literature, this article analyses the impact of immigration on the Canadian labour market at the regional level. For this purpose, 10 provinces of Canada have been selected for this study with the data spanning over 12 years from 2006 to 2017. Through the empirical analysis, the article finds there is a significant negative impact of immigration on the native employment level. Whereas the opposite results are found on the national level and the impact on the income of native workers is found to be negative and significant. The employed natives are also found to be migrating to other states at a higher rate in regions where immigration is higher. These results show that natives employees in the labour market tend to migrate and immigration hence offsetting the wage effects on the regional level.
THE IMPACT OF FLIPPED CLASSROOM APPROACH ON THE WRITING ACHIEVEMENT AND SELF-REGULATED LEARNING OF PRE-SERVICE ENGLISH TEACHERS

The major purpose of this study is to investigate the impact of flipped classroom on pre-service English teachers' Advanced Writing achievement. The study also aims at exploring whether flipped classroom approach makes a difference, if any, on the self-regulated learning of the participants. The participants of this study were selected by convenience sampling method and consisted of fifty-five (N=55) pre-service ELT teachers attending Advanced Writing course and studying at English Language Teaching Department (ELT) at a foundation university in the fall semester of 2017-2018 academic year. Two intact classes were selected as control (N=28) and experimental group (N=27). The control group was exposed to traditional lecture based instruction, whereas the experimental group received the flipped classroom approach. In this quasi-experimental study, data were gathered through pre-post-tests of advanced writing and self-regulated learning scale. Mixed ANOVA analysis was used for data analysis. The obtained results demonstrated that the implementation of flipped classroom approach resulted in better writing achievement, yet self-regulated learning showed no significant difference between groups. Based on these findings, the study provides pedagogical implications and suggestions for integrating flipped classroom approach in the undergraduate programs.
Optimization of Injection Pressure and Injection Timing on Fuel Sprays, Engine Performances and Emissions on a Developed DI 20C Biodiesel Engine Prototype

Biodiesel, as a renewable fuel that has the potential to replace diesel fossil fuels. With properties in the form of viscosity, density, and surface tension, which are higher than diesel fossil fuel, biodiesel produces poor spray characteristics, and also the high cetane number and oxygen content so that the ignition delay is shorter causes the start of combustion will shift more forward, therefore need to improve injection parameters including injection pressure and timing. The aim of this research is to get the optimal injection parameter optimization so as to improve engine performances and emissions. The method used is to increase the fuel injection pressure from 200 to 230 kg/cm2 and the injection timings were retarded from 22° to 16° BTDC. The results show that increasing injection pressure can improve spray characteristics as indicated by shorter penetration and smaller spray diameter of 30% and 9.8%, respectively and increase in spray spread angle of 21.9%. Then the optimization of engine performances and emissions, obtained at an injection pressure of 230 kg/cm2 and injection timing of 16° BTDC with an increase of power and thermal efficiency of 3.9% and 13.9%, respectively and reduction in smoke emissions of 45.2% at high load.
Thermoelectric Study of La2Ti2-xNbxO7 (0≤x≤0.25) Ceramic Materials

La2Ti2-xNbxO7 (x = 0.00, 0.05, 0.10, 0.15, 0.20, 0.25) powders were synthesised via solid state reaction method, followed by sintering at 1673 K in a reducing atmosphere of 5% H2/N2 gas. The crystal structure, microstructure and thermoelectric (TE) properties of the pure and Nb-doped La2Ti2O7 ceramics were investigated. All compositions were single phase with porous microstructures consistent with their low experimental densities. Thermoelectric results of Nb-doped compositions showed improved properties in comparison to pure La2Ti2O7, suggesting that cation doping has the potential to improve the thermoelectric properties. Generally, the TE results obtained are not suitable for thermoelectric applications. However, the high Seebeck coefficient (≥ 190 μV/K) and glass-like thermal conductivity (≤ 2.26 W/m. K) values achieved have opened a new window for exploring the thermoelectric potentials of La2Ti2O7 and other related oxides.
The Role of Ambient Temperature and Plasma Osmolarity on Clinical Outcomes of Acute Myocardial Infarction Patients during Hajj

Background: Performance of Hajj is physically very demanding, especially if performed during the summer season. The aim of this study is to evaluate the importance of ambient temperature and dehydration, indicated by plasma osmolarity on the clinical outcomes of cardiac patients during Hajj season in 2017. Methods: We included all patients referred to tertiary center with acute coronary syndrome during Hajj period of 2017. Plasma osmolarity was calculated using concentrations of sodium, plasma glucose, and blood urea nitrogen at admission. Patients were stratified by groups (G) of admission osmolarity, clinical outcome was compared. The primary endpoints were in-hospital mortality, length of stay, Cardiac complications (heart failure, re-infarction, arrhythmia, shock and thrombus formation), left ventricular function and readmission rate. Result: Total of 300 patients were identified with mean age 56.2 ±12.1, 84% males and 97(32%) were pilgrims. They were exposed to average heat index 61.9 ±10.6° C. Significantly longer admissions were found in the group of higher osmolarity (G2) (≥295 mos/L) as compared to patients with normal osmolarity in G1 [6.7 ±14.9 VS 4.0 ±4.5, P=0.045]. Total in-hospital death rate was 4.3% (13). Using Binary regression analysis; osmolarity Group [p=0.009], Pilrgrim [P=0.005], Heat index [ P=0.005], were independent predictor of inhospital mortality, while Heat index is the only independent predictor for MACE [P=0.001]. Conclusion: Plasma osmolarity and heat index significantly affect cardiac patient’s outcome. These finding underscore the importance of health awareness of protection from dehydration for pilgrims during summer season.
Percolating Network of Ultrathin Gold Nanowires and Silver Nanowires toward “Invisible” Wearable Sensors for Detecting Emotional Expression and Apexcardiogram

2 nm thin gold nanowires (AuNWs) have extremely high aspect ratio (≈10 000) and are nanoscale soft building blocks; this is different from conventional silver nanowires (AgNWs), which are more rigid. Here, highly sensitive, stretchable, patchable, and transparent strain sensors are fabricated based on the hybrid films of soft/hard networks. They are mechanically stretchable, optically transparent, and electrically conductive and are fabricated using a simple and cost‐effective solution process. The combination of soft and more rigid nanowires enables their use as high‐performance strain sensors with the maximum gauge factor (GF) of ≈236 at low strain (<5%), the highest stretchability of up to 70% strain, and the optical transparency is from 58.7% to 66.7% depending on the amount of the AuNW component. The sensors can detect strain as low as 0.05% and are energy efficient to operate at a voltage as low as 0.1 V. These attributes are difficult to achieve with a single component of either AuNWs or AgNWs. The outstanding sensing performance indicates their potential applications as “invisible” wearable sensors for biometric information collection, as demonstrated in applications for detecting facial expressions, respiration, and apexcardiogram.
A systematic review and taxonomy of web applications threats

ABSTRACT Nowadays, web application security is one of the relevant issues in the IT security domain due to the continued growth in the number of web-related attacks. As a result, attacks, with various and varied motivations, have developed and become increasingly sophisticated. They mainly target data related to economic activities. Thus, they cause significant damage to the overall functioning of information systems. To address the various threats, several robust taxonomies exist in the literature. Each taxonomy and classification has advantages and limitations. We first define the different threat classifications related to the context of Web applications. The objective of this analysis is to provide a synthesis of the advantages and disadvantages of each classification. The current work analyses different taxonomies for web applications threats, in order to propose our proper taxonomy. The proposed taxonomy takes advantage of the benefits of existing taxonomies and provides an integrated approach for classifying both client-side and server-side attacks. The finding will help researchers to find a clear and detailed taxonomy of the different threats related to web applications.

Religious orientation, religious involvement, and religious coping predict university students’ thinking styles

ABSTRACT This study explores how religious orientation, religious involvement, and religious coping are related to thinking styles among university students in mainland China. The Thinking Styles Inventory-Revised II (TSI-R2), Age Universal Intrinsic/Extrinsic Scale-12, the religious involvement scale, and the brief RCOPE were administered to 933 students. Results showed these three inventories are reliable among Chinese students, and that religiousness significantly positively predicted Type I thinking styles (i.e. more creativity-generating, less structured, and cognitively more complex). This study implicated that university students’ religious orientation, religious involvement, and religious coping deserve attention; professional religious personnel could promote students’ Type I thinking styles by increasing their religiousness within the legal places of worship; religious university students may improve their Type I thinking styles through more actively participate in off campus religious activities. The limitations and contributions of this research are also discussed.
