In this work, waste cooking palm oil (WCPO)-based carbon nanotubes (CNTs) with encapsulated iron (Fe) nanoparticles have been successfully produced via modified thermal chemical vapor deposition method. Based on several characterizations, the dense WCPO-based CNT was produced with high purity of 89% and high crystallinity proven by low ID/IG ratio (0.43). Moreover, the ferromagnetic response of CNTs showed that the average coercivity and magnetization saturation were found to be 551.5 Oe and 13.4 emu/g, respectively. These produced WCPO-based CNTs were further used as heavy metal ions adsorbent for wastewater treatment application. Some optimizations, such as the effect of different adsorbent dosage, varied initial pH solution, and various heavy metal ions, were investigated. The adsorption studies showed that the optimum adsorbent dosage was 1.8 g/L when it was applied to 100 mg/L Cu (II) solution at neutral pH (pH 7). Further measurement then showed that high Cu (II) ion removal perc.....

This study examined the efficiency of callus induction on optimum concentrations of NAA (?-naphthaleneacetic acid) and BAP (6-benzyladenine) from culturing stem and leaf explants of finger eggplant (Solanum sp.) and investigated the phytochemical constituents of callus tissue. Seeds were sterilized by using 3 and 5 % Clorox solution, which gave the highest number of survival seeds (100 %) and were grown in vitro plantlets. The highest frequency of callus induction (100.00 � 0.00 %) was obtained from stems and leaf explants that were excised from in vitro plantlets. The stem explants cultured on MS medium consisted of 1.0 mg/L NAA + 1.0 mg/L BAP, giving the maximum mean callus fresh weight (0.14 � 0.05 g). Meanwhile, the leaf explants cultured on MS medium consisted of 0.5 mg/L NAA + 2.0 mg/L BAP, generating the maximum mean callus fresh weight (0.48 � 0.10 g). The highest frequency of callus induction (88.00 � 1.60 %) was obtained in solidified MS medium supplemented with 0.5 m.....

Predicting arrival guest is an essential step in estimating the Malaysia economic impact, particularly in short and long-term COVID-19 crisis. Neural Network family of models has been widely used in economic and tourism. Most of the study used single layer of fed forward propagation system, it is because of less sampling variation in Neural Network. However, apparently the multilayer provides a better predicting result but its disadvantage is to deal with high sampling variation. The motivation of this study is to enhance the ability of multilayer Neural Network in predicting the arrival guest. In this study, a hybrid model based on Bootstrapping the Neural Network proposed to predict the arrival guest of Singapore in Malaysia. The weights of variables to the first hidden layer nodes are bootstrapped. The subsequent hidden layer takes the bootstrapped weights in order to obtain the Neural Network output. The prediction obtained by hybrid model has been compared with conventional multil.....

Among the most significant governance issues currently faced by the modern corporation are those relating to diversity, such as gender, and independence of directors. Another modern issue facing managers is social media disclosure. The paper aimed to address several research questions, mainly the association between boards of directors? composition: board diversity, and board independence, and the level of financial disclosure on social media by UAE firms. The research data is collected from 103 firms listed in the UAE financial markets for the period 2018?2019. The research result indicates that the relationship between board composition and the social media financial disclosure is significant and positive. This study provides contributions to UAE?s government, policymakers, and regulators with regards to two important issues, particularly gender diversity on the board as well as the modern disclosure tools that could be used by firms to reduce the agency problem. ? 2021, The Author(s.....

The sterling mechanical properties of titanium alloys have distinguished them as an essential material for varied applications especially in biomedical fields. The combination of good corrosion resistance in addition to light weight, non-toxicity and an outstanding biocompatibility makes them a sought-after material for production of medical implants. Owing to the surging demand for durable implants, it has become exigent for increased developmental researches on biomaterials to be accelerated. This will result in significant increase in implant production and Ti alloys will play a vital role among the several materials presently in use. Hence, this review critically analysed the important roles Ti alloys have played thus far in the implant production industry and recent development of titanium-based alloys with low elastic modulus similar to human bones as well as improved biocompatibility and wear resistance. ?

Kicking movement is process of moving position on leg. Biomechanical analysis explains kick performance which influenced by kinematics and kinetics factors. The research purpose analyzed biomechanical long pass movement. This research is both qualitative and quantitative. The research sample are 11 Indonesian woman football players who were taken by saturated sampling. Data in the form of long pass kick video with airborne ball test. Data analyzing used Kinovea software to determine the flexion angle of backswing kick leg, hip angle, and distance to target, then looking for the force, power, and energy in kick motion. The motion analysis shown that sample 3 produces closest distance to target as far as 0.65 m which done with flexion angle of backswing knee is 740 and hip angle of 640. The force exerted by sample 3 is 10.09 N, resulting in a ball speed of 22.42 m/s and a kinetic energy of 113.12 Joule, potential energy of 14.64 Joule and mechanical energy of 127.76 Joule. It can be conc.....

As part of our ongoing study of the specialised metabolites present in brown algae belonging to the Cystophora genus, eight new steroids including three pairs of diastereoisomers were isolated from Cystophora xiphocarpa (Harvey) (Sargassacea, Fucales). The metabolites identified by standard spectrometric methods are (16S,22S)-16,22-dihydroxyergosta-4,24(28)-dien-3-one and (16S,22R)-16,22-dihydroxyergosta-4,24(28)-dien-3-one, (16S,22S,24R)-16,22,24-trihydroxyporifera-4,28-dien-3-one and (16S,22S,24S)-16,22,24-trihydroxystigma-4,28-dien-3-one along with (16S,22S,24E)-16,22-dihydroxystigma-4,24(28)-dien-3-one and (16S,20S)-16,20-dihydroxyergosta-4,24(28)-dien-3-one.

The aim of this chapter is to examine the strategic enhancement of global mindset and open mind to supplement the learning atmosphere into being more worldwide in looking at the intercultural divergence. The essential support to interact internationally among the students attempts to enhance cultural awareness and global competence to achieve social development to meet the needs in the global citizen learning. The critical review of several literatures was conducted through arranging the keywords and followed with extracting the data analysis to interpret the results. Both critical analysis and synthesis towards interpreting, conceptualizing, and modelling of worldwide quality together with open mind in intercultural competence. With critical exploration, the finding reveals that an attempt to empower global mindset and an open mind refers to the initiative in encouraging the extent of worldview leading to the social development for active citizenship in order to enable the mutual conv.....

In the present study, poly(?-caprolactrone) nanocapsules were loaded with betel essential oil and used as anti-mosquito spray formulations for cotton and polyester fabrics for the first time. The release and retention of betel essential oil on the fabrics after sequential washing and heating were determined using UV-Visible spectrophotometry. The repellent activity of cotton and polyester fabrics was evaluated using an Excito chamber test on Aedes aegypti mosquitoes. The nanocapsules exhibited high betel essential oil encapsulation efficiency (98.70%) and remained stable throughout 60 days of colloidal system stability study. The encapsulation of betel essential oil in the lipid core of polymer nanocapsules was able to increase the durability towards washing and heating, as the fabrics still exhibited a good repellency of up to 47% against mosquitoes even after 5 sequential washing cycles. Results obtained from this study highlight the feasibility of betel essential oil-loaded lipid-co.....
