Quality of Life After Orthopedic Procedures at Buraydah Central Hospital and King Fahad Specialist Hospital in Qassim Region, Saudi Arabia.

Aim Patients' perspectives on their condition and treatment, their sense of need for healthcare, and their preferences for care and outcomes are all addressed by quality of life metrics. Therefore, it is important to all health professionals and patients involved in orthopedic surgery. This study aimed to evaluate the quality of life after orthopedic procedures and how its results could potentially be used for future improvement.

Arabic Validation of the Amsterdam Preoperative Anxiety and Information Scale.

Background  is a frequent and challenging problem that may impact a patient's postoperative pain and satisfaction. The level of a patient's anxiety needs to be assessed through a valid and reliable instrument to prevent and treat preoperative anxiety effectively. One such reliable measurement scale is Amsterdam Preoperative Anxiety and information scale, which is based on a self-reported questionnaire but is still not validated in Arabic.

Comparison of Two Types of Preparation for Laminate Veneer with Three Types of All-Ceramic Materials.

Objective:  The objective of this study was to compare types of veneer preparations and their combination with three materials.

Materials And Methods:  Two finite element models were specially prepared used representing window and wrap around preparation for veneers. The "central incisor" tooth geometry was acquired using a laser scanner, and then its surface was adjusted to form a solid model prior to the removal of each preparation separately.

Revealing the optoelectronic properties of Re-based double perovskites using the Tran-Blaha modified Becke-Johnson with density functional theory.

Density functional theoretical (DFT) calculations were carried out to explore the electronic and optical properties of double ordered BaNaReO, BaLiReO, and SrLiReO perovskites by employing the state-of-the-art exchange-correlation potential, i.e., Tran-Blaha modified Becke-Johnson for the electronic system.

Dual-Color Lasing Lines from EMPs in Diluted Magnetic Semiconductor CdS:NiI Structure.

Have one ever seen a semiconductor that can issue two-color lasing lines? The diluted magnetic semiconductor (DMS) can do this. Here, we have observed dual lasing lines of 530 nm and 789 nm from a DMS structure of CdS:NiI, in which the excitonic magnetic polaron (EMP) and localized excitonic magnetic polaron (LEMP) are excitations out of ferromagnetic (NiS) nanocluster and NiI nanoclusters within CdS lattice; both of them could lead to the collective EMP state at high excitation and therein produce coherent emission lines simultaneously. This occurrence is due to the superposition of EMP near CdS bandedge and the combination of the charge-transfer band of (NiI) cluster with the LEMP within CdS lattice by overcoming the strong electron correlation of NiI cluster in a DMS structure, evidenced also by ab initio calculation.

Electronic structure and optical properties of TaNO: An ab initio study.

We performed ab initio calculations to study the structural and optoelectronic properties of simple and slab phase TaNO using density functional theory (DFT), in which the full potential augmented plane wave (FP-LAPW) method was implemented using the computational code Wien 2k. The modified Becke-Johnson potential (mBJ-GGA) was used for these calculations. The calculated band structure and electronic properties revealed an indirect bandgap for simple TaNO (3.

Transfer factors for natural radioactivity into date palm pits.

Palm pits are used in various human and animal feed products. In this study, the natural radioactivity levels from soil and date palm pits of 9 samples collected from major date palm farms in three different regions (Buraidah, Al-Zulfi and Al-Majmaah) of Saudi Arabia were determined by using the high purity germanium (HPGe) gamma-ray spectrometer. The mean activity concentrations of Ra, Th, Cs and K in soil samples were 12.
