Stabilization and solidification of arsenic contaminated silty sand using alkaline activated slag.

Contamination of soils by arsenic represents a significant environmental and public health risk, making effective remediation strategies a pressing concern. One commonly employed technique is stabilization and solidification, which involves the addition of stabilizing binders such as cement to immobilize arsenic. This study investigates the potential of alkaline activated slag for stabilization and solidification of arsenic-contaminated soil, employing the toxic characteristic leaching procedure (TCLP) and unconfined compressive strength (UCS) tests.

Arthroscopic Repair of a Coronoid Process Fracture: A Case Report.

Case: A 68-year-old woman sustained an isolated type III left coronoid fracture after mechanical ground-level fall. The patient underwent left elbow arthroscopy with minimally invasive arthroscopic reduction and internal fixation of the coronoid fracture using Arthrex Mini TightRope. The patient achieved successful elbow stabilization with a postoperative Mayo Elbow Score of 100.

Return to Sports Following Meniscal Allograft Transplantation Is Possible but Remains Questionable: A Systematic Review.

Objective: To evaluate the return to sports rate and time following meniscal allograft transplantation (MAT).

Methods: PubMed, Web of Science, and Embase were searched in December 2020. Eligibility criteria included clinical studies reporting the return to sport rate following MAT with ≥12-month follow-up.

A comparison between constitutive models for the municipal solid waste.

This paper compares the behavioural models of municipal solid waste (MSW) using the corresponding experimental data. To do so, the proposed models are first reviewed and, then, the algorithms and codes of different models are written. After obtaining each model's algorithm, the same experimental data are considered as input, and the strain-stress curve is plotted for each model.

There is an App for That: Mobile Technology Improves Complication Reporting and Resident Perception of Their Role in Patient Safety.

Unlabelled: Morbidity and mortality (M&M) conferences are rooted within the culture of medicine. They serve a role in every training program and have been mandated by the Accreditation Council for Graduate Medical Education in surgical programs since 1983. Despite the patient safety improvements and educational benefits of these conferences, many adverse events are grossly under-reported.

Hip Adductor Longus Tendon Origin Anatomy Is Consistent and May Inform Surgical Reattachment.

Purpose: To define the topographic anatomy of the footprint of the adductor longus origin on the pubis and its underlying bony morphology to better inform surgical repair of adductor longus tendon injuries.

Methods: Five cadaveric pelvis specimens were dissected, making 10 adductor footprints available for analysis. The adductor longus tendon origin was isolated and the surrounding tissue debrided.

Prosthetic Bearing Surfaces in Anatomic and Reverse Total Shoulder Arthroplasty.

Total shoulder arthroplasty (TSA) and reverse TSA have provided an effective treatment for glenohumeral osteoarthritis; however, longevity of the procedure may be limited by osteolysis and polyethylene wear. In TSA, glenoid component failure occurs through several mechanisms, the most common being aseptic loosening and polyethylene wear. Newer bearing surfaces such as highly cross-linked ultra-high-molecular-weight polyethylene, vitamin E processing, ceramic heads, and pyrolytic carbon surfaces have shown improved wear characteristics in biomechanical and some early clinical studies.

Standing electric scooter injuries: Impact on a community.

Background: This study investigates the impact of standing electric scooter-related injuries within an entire integrated hospital system.

Methods: We performed a retrospective review of patients involved in standing electric scooter incidents presenting throughout an urban hospital network over a 10 month period. Rates of Google searches of scooter-related terms performed locally were used as a surrogate for ride frequency.

A laboratory study on the MSW mechanical behavior in triaxial apparatus.

Shear strength characterization of MSW materials is a mandatory task when performing analyses related to landfill design and landfill geometry improvements. Despite the considerable amount of research focusing on MSW mechanical behavior there remain certain aspects which are not completely understood and deserve attention in particular the case of the undrained behavior of MSW. This paper presents the results of a comprehensive laboratory testing program using a large-scale triaxial apparatus at the Federal University of Bahia, Salvador, Brazil.

Municipal solid waste effective stress analysis.

The mechanical behavior of municipal solid waste (MSW) has attracted the attention of many researchers in the field of geo-environmental engineering in recent years and several aspects of waste mechanical response under loading have been elucidated. However, the mechanical response of MSW materials under undrained conditions has not been described in detail to date. The knowledge of this aspect of the MSW mechanical response is very important in cases involving MSW with high water contents, seismic ground motion and in regions where landfills are built with poor operation conditions.
