USING THE TECHNOLOGY ACCEPTANCE MODEL (TAM) IN EXAMINING ABSHER SYSTEM ACCPETANCE IN THE KINGDOM SAUDI ARABIA

In this era of technological disruption, people are much oriented to offer and experience new technological interventions in their daily activities. Information and communication technology (ICT) hold a pivotal designation in allowing the integration of technological interventions with daily life activities. Technology Acceptance Model (TAM) proved as the helping hand for making this situation much more sophisticated so that global technological determinism that is at the threshold of revitalization can go through a realistic situation. Absher information system that is primarily adopted by the Saudi Arabia government for facilitating their e-government initiatives demonstrated in this study. TAM used as the theoretical background for justifying the holistic applicability of Absher services. Absher is a strategic move by the Saudi government for accommodating betterment in e-governance. Thus, different aspects of global e-government principles are appropriately demonstrated in this study so that a proper justification for Absher usefulness can be displayed. Also, in this study, several theoretical persuasions are augmented, followed by taking into account variables such as perceived usefulness (PU), perceived ease of use (PEOU), behavioral intentions (BI), attitude towards use (ATU), and user satisfaction (US). The survey was conducted by the researcher, taking into account a sample of 300 Absher users from KSA. Data analysis has been conducted by the researcher using a linear regression model in which the T-test, ANOVA test, and Cronbach's' alpha test. The study results revealed that most users provide positive and high attitudes towards the use of the Absher System. Also, there is a positive correlation between ease of use and the user's attitudes towards using Absher System. Furthermore, the study found that the majority of participants thinks that using Absher System is useful for them. JEL: H10; H7

AN ANALYSIS OF THE OLD, CURRENT, AND FUTURE SYSTEMS OF THE HEALTHCARE SERVICES IN SAUDI ARABIA

This report offers a thorough summary of Saudi Arabia's healthcare services' past development as well as their possible future. Over time, Saudi Arabia's healthcare system has undergone a substantial transformation, moving from a decentralized and resource-constrained structure to one that is more organized and efficient. Early in the new millennium, the Health Transformation Program (HTP) was introduced, which was a game-changer that led to advancements in healthcare staff, modernization, and infrastructure. Future developments in Saudi Arabia's healthcare system are anticipated by Vision 2030, which calls for a greater dependence on technology, telemedicine, involvement from the private sector, and a primary focus on preventative and basic healthcare. There are still issues to be resolved, such as managing regional differences, adjusting to an aging and expanding population, and promoting public-private partnerships. It is anticipated that Saudi Arabia's healthcare system would continue to change, driven by the goal of offering its people high-quality, affordable, and accessible healthcare

CaO impregnated highly porous honeycomb activated carbon from agriculture waste: symmetrical supercapacitor study

This study presents the electrochemical studies of activated carbon prepared from palm kernel shell (ACPKS), with CaO impregnation. The CaO is obtained from chicken eggshell waste to produce CaO/ACPKS, which shows highly porous honeycomb structure with homogeneous distribution of CaO nanoparticles (30–50 nm in size). The prepared materials are evaluated as supercapacitor electrodes by testing their electrochemical characteristics. A high specific capacitance value of 222 F g−1 at 0.025 A g−1 is obtained for CaO/ACPKS, which is around three times higher than that for ACPKS (76 F g−1). In addition, electrochemical impedance data show lower impedance for CaO/ACPKS. Lastly, a practical symmetrical supercapacitor is fabricated by CaO/ACPKS and its performance is discussed

Cone Beam Computed Tomography Evaluation of Root Morphology of the Premolars in Saudi Arabian Subpopulation

Objective: To evaluate root canal configuration and morphology of premolar teeth among Saudi subpopulations using cone beam computed tomography (CBCT). Material and Methods: In this retrospective cross-sectional study, CBCT images of 314 patients comprising 346 maxillary and 412 mandibular first premolar (FPM) teeth, 298 maxillary and 387 mandibular second premolar (SPM) teeth were analyzed to evaluate the number of roots, root canal morphology, and configuration based on the Vertucci's classification. The average intra-class correlation coefficient value was 0.931. Results: In the maxillary first premolar, 52.6% were two separate rooted and single rooted teeth, with one canal in 81.2% of the maxillary second premolar. Among the mandibular FPM, 96.6% of the teeth had one root and canal, and 97.9% of mandibular SPM had one root and canal. Type 1 canal configuration was seen as most common in all premolars. The number of roots in mandibular premolars did not reveal the difference among gender. Conclusion: Wide variations in root canal morphology and canal configuration system exists among maxillary and mandibular premolar teeth

One-step production of pyrene-1-boronic acid functionalized graphene for dopamine detection

A facile molecular wedging method is used to exfoliate graphite flakes into graphene sheets, with concurrent functionalization to form pyrene-1-boronic acid functionalized graphene (PBA/G). Different techniques are used to characterize the prepared materials such as field emission scanning electron microscope, energy dispersive X-ray analyzer, Raman, Fourier transformed infrared spectroscopy and fluorescence spectroscopy to evaluate their structural and morphological characteristics. The intercalation of PBA into graphite sheets, followed by exfoliation can be observed under the electron microscope. Elemental analyses show that the PBA acts more than intercalant, it is functionalized onto the graphene sheets upon exfoliation to form PBA/G. Raman analysis indicates PBA/G has a lower number of graphene layers as a result of successful exfoliation by PBA. Electrochemical impedance studies show that the PBA/G possesses high affinity for dopamine through the diol groups interaction, which renders it to have enhanced detection for dopamine

Magnetic Electrodeposition of the Hierarchical Cobalt Oxide Nanostructure from Spent Lithium-Ion Batteries: Its Application as a Supercapacitor Electrode

In this study, electrodeposition of cobalt oxide (Co3O4) from spent lithium-ion batteries is successfully enhanced by the magnetic field effect. In the presence of magnetic field, well-defined hierarchical Co3O4 nanostructures with higher electroactive surface area are formed during the electrodeposition process. Electrochemical analysis shows that the enhanced Co3O4 nanostructures exhibit excellent charge storage capabilities of 1273 F g–1 at 1 A g–1, approximately 4 times higher than the electrodeposited Co3O4 that is formed without magnetic field effect. It also reveals the high cycling stability of enhanced Co3O4 nanostructures, with 96% capacitance retention at 5000 charge discharge cycles. The results manifest the enhancement of Co3O4 recovery from spent lithium-ion batteries, which can be the potential electrode material for supercapacitor application

Ferrocene functionalized multi-walled carbon nanotubes as supercapacitor electrodes

Modified multi-walled carbon nanotubes (MWCNTs) functionalized by a redox-active ferrocene (Fc-MWCNTs) were successfully synthesized to enhance the electrochemical performance of MWCNTs for supercapacitor application. The ferrocene moieties were attached to the surface of MWCNTs via a thiourea linker with anions-interacting capability. The Fc-MWCNTs were characterized using XPS, FTIR, SEM, TGA, DTG, and XRF methods. The electrochemical performance details were investigated using cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance spectroscopy. The Fc-MWCNTs electrode showed excellent capacity retention (90.8% over 5000 cycles) and a specific capacitance of 50 F g−1 at 0.25 A g−1 that is several times higher as compared to the pristine MWCNTs. The fabricated Fc-MWCNTs is proposed to be a suitable and promising candidate for energy storage material. de

Spin-valve Josephson junctions with perpendicular magnetic anisotropy for cryogenic memory

We demonstrate a Josephson junction with a weak link containing two ferromagnets with perpendicular magnetic anisotropy and independent switching fields in which the critical current can be set by the mutual orientation of the two layers. Such pseudospin-valve Josephson junctions are a candidate cryogenic memory in an all superconducting computational scheme. Here, we use Pt/Co/Pt/CoB/Pt as the weak link of the junction with dCo=0.6 nm, dCoB=0.3 nm, and dPt=5 nm and obtain a 60% change in the critical current for the two magnetization configurations of the pseudospin-valve. Ferromagnets with perpendicular magnetic anisotropy have advantages over magnetization in-plane systems, which have been exclusively considered at this point, as, in principle, the magnetization and magnetic switching of layers in the junction should not affect the in-plane magnetic flux
