The aim of this study was to fabricate and characterize graphene oxide (GO) based electrodes for two types of home-developed water treatment system, namely electrodeposition (ED) and capacitive deionization (CDI) for copper ions (Cu2+) and methylene blue (MB) dye removal. Electrochemical exfoliation was utilized to synthesize GO using custom-made triple-tails (TC14) surfactant. Hydrazine hydrate was utilized as reduction agent to produce TC14-rGO. The TC14-GO and TC14-rGO were then coated via spray coating method on stainless steel (SS) which further utilized as electrodes in ED water treatment system. Meanwhile for CDI system, the TC14-GO sample was sprayed and immersed in activated carbon fiber cloth (ACFC) electrodes. The TC14-GO-based electrodes were characterized using electron microscopy, energy dispersive X-ray, high resolution transmission electron microscopy, X-ray diffraction, fourier transform infrared spectroscopy, UV-Vis spectroscopy and micro-Raman spectroscopy. The atomi.....

Novel zinc alumina bismuth borate glass system was fabricated according to the empirical formula x(ZnO)?5(Al2O3)?30(BiO3)?65-x(B2O3) with x = 0, 5, 10, 15, 20, 25 and 30 mol% using conventional glass melt-quenching technique. The structural, elastic and shielding properties of the ZnO?Al2O3?BiO3?B2O3 glasses were examined by X-ray diffraction (XRD), density, molar volume, ultrasonic velocities, and EPICS2017 simulation. The glass structure's amorphous phase was confirmed by XRD measurement. From the density measurement, the addition of ZnO will increase the density from 4.275 to 5.018 g/cm3 and the molar volume decreased from 44.479 to 38.595 cm3/mol. In addition, the OPD is decreased from 67.45 to 62.19 mol/cm3. The elastic properties approximated from measured shear (VS) and longitudinal (VL) ultrasonic velocities indicated that the decrease of B2O3 in glass network cause the rigidity of glasses increased from 2300 to 2621 m/s and 4082?4540 m/s when the ZnO content increased.

This study examined the influence of cash flow on bank failure prediction in deposit money banks in Nigeria. The study exploited all listed deposit money banks in the Nigerian stock exchange market that have adequate financial reports for a period of ten years, from 2011 to 2020. Data collected were analyzed using descriptive statistics, correlation matrix, and random effect regression model. The study’s findings of the study divulged that net cash flows from investing and financing activities have a positive and considerable influence on bank failure predictions while operating activities such as cash flow have an adverse effect on the likelihood of bank distress prediction. It was also observed that investing and financing activities’ net cash flows are significant cash flow components that predict the likelihood of bank failure and the cash flow model is an effective predictor of bank failure in the Nigerian banking sector. The study recommended that the management of Nigeria’.....

Kajian ini bertujuan untuk membangunkan kit Genetik topik pembahagian sel Tingkatan 4 serta mengenal pasti persepsi pelajar terhadap kit yang dibangunkan daripada aspek reka bentuk, kandungan, kebergunaan dan kepuasan. Kit Genetik ini dibangunkan dengan menggunakan reka bentuk pembangunan berpandukan lima fasa dalam Model ADDIE. Instrumen kajian terdiri daripada borang kesahan muka, kandungan, konstruk soal selidik dan borang soal selidik. Kajian ini melibatkan 40 orang responden yang terdiri daripada pelajar Tingkatan 4 yang ditentukan menggunakan teknik persampelan bertujuan. Data bagi borang penilaian kesahan pakar dianalisis menggunakan nilai peratus persetujuan pakar manakala borang soal selidik kebolehgunaan dianalisis menggunakan analisis deskriptif iaitu min dan sisihan piawai. Dapatan kajian menunjukkan purata persetujuan pakar bagi kesahan muka dan kandungan daripada dua orang pakar adalah tinggi iaitu 100% dan 91.5%. Ini menunjukkan bahawa kajian dapat diteruskan.....

Athletes' food habits and nutritional understanding are closely related and have a significant impact on their performance. Athletes should always consider the importance of nutrition in their growth and development but yet, there still lacks study on nutrition knowledge toward individual sports. The purpose of this study was to determine the differences in prevalence of nutritional knowledge between genders among UiTM Perlis athletes who are playing individual sports. One-hundred and seventeen athletes has completed the Component of Nutritional Questionnaire. The questionnaire consists of 30 questions which test the nutrition knowledge of the athletes. The questionnaire was divided into two sections which consist of section A (covered demographics questions) and section B (the nutritional knowledge questions). The data showed the mean nutrition knowledge score of female athletes (18.98 ± 2.64) was slightly higher compared to male athletes (18.78 ± 2.27), (p = 0.65). The prevalence o.....

Umur mahasiswa universiti teknikal di Malaysia rata-ratanya bermula dari 19 sehingga 24 tahun. Mahasiswa ini terdiri daripada pelajar yang mendaftar di peringkat pengajian diploma dan ijazah sarjana muda. Maka, objektif kajian ini adalah untuk mengenal pasti pandangan mahasiswa universiti teknikal mengenai penggunaan slanga dalam pembentangan kumpulan berbahasa Melayu, menganalisis impak penggunaan slanga dalam pembentangan tersebut serta merumuskan cadangan dan langkah bagi mahasiswa universiti teknikal dalam menggunakan slanga dalam pembentangan tugasan kumpulan berbahasa Melayu. Perbincangan kajian ini turut mengaplikasikan pendekatan pragmatik, iaitu Teori Relevans (Sperber & Wilson, 1986). Dari sudut metodologi, kajian ini berbentuk kuantitatif dengan reka bentuk tinjauan silang dan borang soal selidik yang menggunakan skala Likert dari 1 hingga 5 dan pilihan jawapan “ya” atau “tidak”. Populasi dan sampel terdiri daripada mahasiswa Universiti Teknikal Malaysia Melaka (UTeM.....

Kajian  ini  bertujuan  untuk  mengkaji  hubungan  antara  burnout  dengan  kepuasan kerja dalam  kalangan guru Tadika Islam,Perak. Selain itu, kajian ini juga bertujuan untuk   melihat   tiga    aspek   dalam   burnout   iaitu   keletihan   emosi,   gangguan keperibadian kendiri dan pencapaian  peribadi. Kajian ini menggunakan pendekatan kuantitatif yang melibatkan reka bentuk tinjauan  deskriptif. Seramai 118 orang guru Tadika  Islam,  Perak  dipilih  secara  rawak  untuk  dijadikan   sampel  bagi  kajian  ini. Satu set soal selidik yang terdiri daripada Maslach burnout inventory  (MBI-ES) di sediakan  oleh  Fatima  Eid  Zaid  dan  Majed  Mohammad  (2017)  digunakan  untuk  mengukur tahap burnout guru Tadika Islam,Perak dan satu set soal selidik Teacher Job Satisfaction  Questionnaire (TJSQ) disediakan oleh Cheng dan Chen (2011) di gunakan  bagi  mengukur  kepuasan   kerja  dalam  kalangan  guru.  Data  kajian�.....
