Posterior reduction and fusion of spondylolisthesis has a number of recognized and accepted procedural difficulties dependent on its severity. The Jazz™ Band is a novel system designed primarily for posterior fixation of the spine; however, its uses can be applied to a breadth of spinal conditions. Its benefits include that one size will fit all spinal levels; the connector is designed for multiple union rod diameters and reduced comorbidity when compared with other surgical methods. We present a case of a 26-year-old female with an L5/S1 spondylolisthesis slip angle of 117.4°. A 25° improvement in the spondylolisthesis slip angle was achieved with the use of the Jazz™ Band. The Jazz™ Band demonstrates excellent short-term results, and in order to determine the clinical outcomes and efficacy of the Jazz™ Band system, long-term results and analysis should be performed.

Waste polyethylene (WPE) and virgin polyethylene (VPE) (50:50) thermoplastic have been melt-mixed with biochar (BC) made from orange peels at ratios of 5, 10, and 15(Phr) to evaluate how the filler content affected the mechanical, thermal, optical, electrical conductivity, and electromagnetic interference (EMI). γ-rays was applied to the prepared specimens to assess how radiation affected the created biocomposites. From the obtained results, the combination of BC with γ-rays, at doses of up to 100 kGy, with thermoplastic resulted in an enhanced mechanical property, particularly for composites containing 15 Phr of BC added because of its unique structure and excellent dispersion.

Greenhouse gases (GHGs) have caused great harm to the ecological environment, so it is necessary to screen gas sensor materials for detecting GHGs. In this study, we propose an ideal gas sensor design strategy with high screening efficiency and low cost targeting four typical GHGs (CO, CH, NO, SF). This strategy introduces machine learning (ML) methods based on density functional theory (DFT) to achieve accurate and rapid screening from a large number of candidate gas sensor materials.

The study highlights the significant effects of Zn ions concentration on the optical properties of BaNiZnFeO ferrites, emphasizing the tunability of the band gap through Zn doping and explores their potential to enhance their optical properties. The barium-nickel ferrite powder, with the composition BaNiZnFeO, was synthesized using the ceramic method. The effects of Zn doping were analyzed using X-ray diffraction (XRD) and UV‒visible (UV-Vis) spectroscopy.

Introduction: Music is known to impact attentional state without conscious awareness. Listening to music encourages the brain to secrete neurotransmitters improving cognition and emotion.
Aim Of Work: Analysis of QEEG band width while listening to two music types, identifying different cortical areas activated and which genre has a similar effect to relaxed EEG.

Colloidal quantum-dot light-emitting diodes (QD-LEDs) have been significantly improved in terms of device performance and lifetime by employing zinc oxide (ZnO) as an electron transport layer (ETL). Although atomic layer deposition (ALD) allows fabrication of uniform, high-quality ZnO films with minimal defects, the high conductivity of ZnO has hindered its straightforward application as an ETL in QD-LEDs. Herein, we propose fabrication of Al-doped ZnMgO (Al:ZnMgO) ETLs for QD-LEDs through a supercycle ALD, with alternating depositions of various metal oxides.
