    This study focuses on the encapsulation of silica and graphene nanoparticles and their potential applications. The encapsulation enhances the properties and effectiveness of these nanoparticles, with silica providing stability and graphene contributing to high surface area and electrical conductivity. Characterization of silica-graphene nanoparticles was conducted using various techniques including High Power Microscope (HPM), Scanning Electron Microscope (SEM), Energy-dispersive X-ray spectroscopy (EDS), and 3D Nano Profiler. The antimicrobial activity of silica, graphene, and silica-graphene nanoparticles was evaluated using a disc diffusion assay against E. coli and B. subtilis at varying concentrations. Results showed significant antimicrobial activity, with the inhibition zone being directly proportional to the concentration. Silica-graphene nanoparticles demonstrated higher efficacy against E. coli compared to B. subtilis, attributed to differences in cell wall structure. Statistical analysis using ANOVA confirmed significant differences in antimicrobial activity among the tested components.

    This study was conducted to evaluate the effects of two types of plant growth regulators (PGRs) which are gibberellins (GA3) and Paclobutrazol (PBZ) on the growth and photosynthetic pigment (chlorophyll) of Okra (Abelmoschus esculentus L. Moench) plants. Exogenous applications of GA3 and PBZ with different concentrations (i.e. 20, 40, 80 and 100 mg/L) were sprayed on two-week-old Okra plants under the nursery stage. The control plants were only treated with distilled water. The stem diameter (mm) of treated and control plants was measured weekly. At the end of the experimental period, data on growth characteristics such as plant height (cm), leaf area (cm2) and number of leaves were recorded. The estimation of chlorophyll was measured using the SPAD-502 Chlorophyll Meter. Results showed that the plant morphological characteristics of Okra plants were significantly affected by the application of GA3 and PBZ (P<0.0001). In addition, stem growth (expressed as stem cross-sectional area- mm2) of Okra plants was significantly increased with increasing GA3 concentrations. In contrast, applying PBZ reduced Okra plants' stem growth. This study highlighted the major effects of GA3 and PBZ on the growth of Okra plants when planted under tropical climate conditions.

    The Soil and Vegetation Analysis Development (SPAD) value was correlated to the actual value of chlorophyll content in the Harumanis mango leaf using a developed regression model. Distribution of chlorophyll content in Harumanis mango leaves were mapped using Geospatial Analyst in the ArcGIS. Total chlorophyll content and SPAD value were well established with the polynomial regression model with coefficient of determination (R2) of 0.925. The results show that the measured SPAD value in the morning were comparable to those value made in the evening and the Harumanis leaves located in the middle of the greenhouse have 25–31.3% lower chlorophyll content compared to other parts of the greenhouse.

    The mechanical properties of antisymmetric pineapple leaf fibre (PALF)/carbon hybrid laminate composites have been studied by researchers. The laminates were produced by vacuum infusion, and the void content easement was applied during validation. The laminates were tested on tensile (ASTM D3039) and flexural (ASTM D7264) testing. Analysing the results of tensile testing, it was determined that the laminate composed of PALF as the first layer and carbon as the second layer has the maximum tensile properties, at strength 110 MPa and modulus 6.5 GPa, respectively. After examining the flexural data, it was determined that the laminate made up of the first carbon and second PALF layers had the highest flexural strength and modulus, 235 MPa and 4.6 GPa respectively. Hence, the results imply that the stacking order influences the tensile and flexural properties. As concluded, stacking sequence has significant effect on anti-symmetric laminates.

    High incidences of early aseptic loosening cases have led to numerous analyses on fixation strength of femoral component (FC). This study consists of two objectives: to analyze the correlation between articulating contact area shape conformities and fixation strength, and (2) to analyze the relationship between slanting box patterns of the FC and fixation strength. Two design analyses were constructed: first, using three different types of contact congruence with radius ratios of 0.50, 0.89 and flat. Second, box patterns of the FC were anteriorly slanted at 2, 4 and 6°. The fixation strength of the FC is significantly improved (38.59%) by slanting the box pattern anteriorly as compared to the non-slanted FC design.
