Separation Time of Aluminothermic Reduction Products for Sustainable Silicon Production.

Background: This work was carried out within the framework of the SisAl Pilot project, which is devoted to the environmentally friendly production of silicon. This new method relies on the aluminothermic reduction of quartz in slag, offering a more sustainable alternative to the traditional reduction of silica with carbon in submerged arc furnaces.

Methods: The process takes place in a rotary kiln producing silicon (Si) and alumina slag (actually, a CaO - Al O slag), which must be separated at the end to extract the silicon.

Gene expression analysis of neuropeptides in oral mucosa during periodontal disease in non-human primates.

Background: Neuropeptides (NPs) are innate pivotal regulators of the immunoinflammatory response. Nevertheless, their role in the pathogenesis of periodontal disease remains unknown. Changes in gene expression of 10 NPs and 16 NP receptors (NPRs) coincident with the initiation, progression, and resolution of periodontitis were determined.

Resolution of Implant-Induced Neurosensory Disturbance: A Procedural Failure.

Purpose: This case report describes the improvement of a patient's neurosensory symptoms after the removal of a mandibular implant within 24 hours of initial placement. After 1 year, neurosensory symptoms resolved, and a different sized dental implant was successfully placed at the same surgical site.

Materials And Methods: A 45-year-old woman experienced neurosensory disturbance along the inferior alveolar mandibular nerve after a dental implant surgery.

Psychometric validation of the Multidimensional Acceptance of Loss Scale.

Objective: To develop and field test the Multidimensional Acceptance of Loss Scale to measure disability acceptance based on the four value changes identified by Beatrice Wright.

Design: Quantitative descriptive design using exploratory factor analysis to determine the factorial validity of the Multidimensional Acceptance of Loss Scale.

Setting: The Canadian Paraplegic Association.

Psychometric validation of a subjective well-being measure for people with spinal cord injuries.

Purpose: The researchers examined the factorial validity and the concurrent validity of the Sense of Well-Being Inventory (SWBI) based on a sample of Canadians with spinal cord injuries (SCI) in the community.

Method: One hundred thirty-two participants were recruited from the Alberta, Saskatchewan, Nova Scotia, and Manitoba chapters of the Canadian Paraplegic Association. Mean age of participants was 45.
