| 1 | 2019 Thesis | The mediating effect of innovation on the relationship between entrepreneurial competencies and business success in Malaysia Azmi Umar This study aims to analyse the impact of Entrepreneurial Competencies, Innovation,
and Business Success among owners and managers in Small and Medium Enterprise (SMEs) to address the
high rate of business failure. Quantitative approaches through the use of survey were used in this
study. Data were collected using questionnaires involving 407 owners and managers of SMEs in
manufacturing, services and other sectors. Respondents were chosen using using Stratified Random
Sampling technique. Multiple Regression Analysis indicated that 53 percent of the variation in
Business Success were explained by Entrepreneurial Competencies and Innovation. The findings also
showed that Entrepreneurial Competencies contributed significantly to Business Success (β=0.190,
S.E=0.051) and Innovation (β=0.198, S.E=0.013). Further, Innovation contributed significantly to
Business Success (β=1.035, S.E=0.226). This study also showed that Innovation served as partial
mediator betwe..... 6401 hits |

| 4 | 2018 Article | The structural, physical and optical properties of borotellurite glasses incorporated with silica from rice husk Umar Saad Aliyu From the agricultural waste of rice (rice husk), high purity SiO2 with about 98.548 % purity was extracted using a very simple room temperature leaching method. Using the rice husk extracted silicate, a system of silicate borotellurite glasses was fabricated with composition equation [(TeO2)0.7 (B2O3)0.3]1-x (SiO2)x with x= 0.0, 0.1, 0.2, 0.3 and 0.4. The density and molar volume were measured, and Fourier transform infrared (FTIR), X-ray diffraction (XRD) and UV-Vis analyses were performed on the glasses. Both the density and molar volume decreased and the XRD pattern confirmed the glasses’ amorphous nature. The FTIR showed the presence of TeO3, TeO4, BO3, BO2O, SiO4, and H3BO3 structural units in the glasses. The concentrations of TeO3, TeO4, BO3 and BO2O structures were determined by the deconvolution of the FTIR spectra using an Origin software. The optical energy band gap, index of refraction, oxygen packing density (OPD), molar refractive index, metallization criterion and pola..... 1098 hits |
| 5 | 2020 Article | Theoretical elastic moduli of TeO2 – B2O3 – SiO2 glasses S.A. Umar In this work, the elastic moduli of silica based borotellurite glass system with compositional formula; [(TeO2)0.7 (B2O3)0.3]1-x (SiO2)x with x= 0.0, 0.1, 0.2, 0.3 and 0.4 was studied using theoretical models. Makishima and Mackenzie, bond compression, Rocherulle, and ring deformation models were employed in the calculation of the elastic moduli, Poisson ratio, packing density, dissociation energy, cross-link density, average stretching force constant and the glass network ring size of the studied glasses. The values of the elastic moduli obtained from the Makishima and Mackenzie model were found to be lower than those obtained from the Rocherulle model and the value from the bond compression model was reported to be highest among the three models. In all the models, the elastic moduli increased with an increase in the concentration of silica in the glass composition. Therefore, it satisfied the original intention of improving mechanical strength to achieve high Young modulus which is ..... 998 hits |
| 6 | 2018 Thesis | Motivasi kesukarelawanan dalam kalangan guru pelatih Institut Pendidikan Guru di Sarawak Adiba Umar@Adli Kajian ini bertujuan untuk memahami pelbagai dimensi motivasi kesukarelawanan
(nilai, kefahaman, peningkatan, kerjaya, sosial dan perlindungan) yang wujud dalam
kalangan guru pelatih Institut Pendidikan Guru di Sarawak yang terlibat dalam kursus
Bina Insan Guru (BIG). Kursus BIG merupakan kursus selama enam semester yang
mendedahkan guru pelatih dengan aktiviti yang dapat memupuk kemahiran insaniah
antaranya melalui program kemasyarakatan dan kesukarelawanan. Kajian ini juga
menganalisis korelasi antara pelbagai pembolehubah iaitu dimensi motivasi
kesukarelawanan, tahap kepuasan dan kesediaan penglibatan berterusan sebagai
sukarelawan. Kaedah pengumpulan data adalah melalui soal selidik yang diadaptasi
daripada Volunteer Functions Inventory (VFI). Seramai 204 orang guru pelatih
sepenuh masa IPG di Sarawak dipilih sebagai responden kajian. Pemilihan responden
adalah secara persampelan rawak iaitu guru pelatih tahun akhir yang telah lengkap

| 7 | 2019 Article | Determinants of entrepreneurial competencies development in small and medium enterprises Azmi Umar This paper is to investigate the impact of key factors that influence the development of entrepreneurial competencies in Malaysian SMEs, both in the manufacturing sector and services sector. This is vital because the economy of Malaysia is partially depending on the contribution of SMEs and the roles played by SMEs. The statical sample population of this research includes 407 owners and manager involved in SMEs. For data collection, a standard questionnaire using seven-point Likert scale and 72 items were used to evaluate 12 entrepreneurial competencies and four items that influence the development of entrepreneurial competencies. Data were analyzed using SPSS version 21 and SEM-Amos version 21. The results confirmed, education was significantly affecting the development of entrepreneurial competencies among entrepreneurs, while the training before business set-up, training after business set-up and work experience have no effect on the development of entrepreneurial competencies.

| 8 | 2021 Article | Oxide ion/electronic polarizability, optical basicity and linear dielectric susceptibility of TeO2 - B2O3 - SiO2 glasses Saad Aliyu Umar A system of bio-silica borotellurite glasses was fabricated based on the chemical formula [(TeO2)0.7 (B2O3)0.3]1-x (SiO2)x with x = 0.1, 0.2, 0.3, and 0.4 using the melt-quenching technique using silica (98.548% SiO2, from rice husk), TeO2 (Alfar Aeser, 99.9%) and B2O3 (Alfar Aeser, 99.9%). Measurements and characterizations such as density and molar volume measurements, XRD analysis, FTIR, and UV?Vis spectroscopes were performed on the studied glasses. The objective was to determine the glasses? applicability in optoelectronics, non-linear optics, and laser technologies through polarizability, linear electric susceptibility, and optical basicity study. Apart from confirming the amorphous nature of the glasses, the XRD analysis identified the presence of a crystalline phase of tellurium oxide (?-TeO2) formed. The FTIR spectral study revealed the presence of TeO3, BO3, and SiO4 structural units in the studied glasses. The refractive index (2.3026 ? 2.2651), molar polarizability (8.0696 ..... 1144 hits |

| 10 | 2022 Article | Theme and trend forecast for Malaysian woman modest wear in year 2024 (idea for raya OOTD) Nur Fatin Umar Fashion trend forecasting is the prediction of mood, behaviors and buying habits of the consumer. It is no longer a question of identifying your customers by demographic and sociographic. Malaysia does not have any forecaster that predict the upcoming trend for fashion industry. Usually, Malaysian designers will usually refer to the international forecaster such as WGSN or trendwatching.com or else, to gain some idea to produce a design. This study was focused on the forecast of modesty fashion specifically for year 2024. The objectives were 1. To establish a local trend forecasting and theme to use in local modest clothing. 2. To analyses the trend forecast for modest wear on year 2024. 3. To proposed a theme forecast of modest wear based from collected data of trend forecast for 2024. Quantitative method was used in this research. The questionnaire was created undertake a survey on the Trend Forecasting for Malaysia Modest Wear for year 2024 among woman 18 to 30 years old.
