Article Synopsis
  • The study introduces a new electrochemical Birch reduction method utilizing a compact Taylor vortex reactor, achieving productivities exceeding 80 g per day.
  • It employs a unique setup with a static aluminum outer electrode and a rotating stainless steel inner electrode, where high selectivity for different naphthalene reductions can be achieved by altering the current.
  • Additionally, the research demonstrates efficiency in reducing lithium bromide and dimethylurea concentrations while maintaining high reaction yields, successfully producing dihydronaphthalene from 1-aminonaphthalene with a projected output of over 100 g per day.

Purpose Of Review: "Distance-learning" encompasses a variety of didactics, from self-directed online learning to focused courses and programs. Despite increasing internet availability, focused distance-learning courses are rarely practiced in low- or middle-income countries, particularly among non-physician anesthetists. This review aims to discuss the availability, significance, and challenges of distance-learning programs for non-physician anesthesia providers in low-resource settings.

Introduction: Chronic pain is one of the most prevalent causes of disability worldwide, and digital interventions may be one of the ways to meet this need. Randomised controlled trials have demonstrated that digital interventions can be effective in treating chronic pain. This study aimed to establish the clinical effectiveness of a web-based pain management programme (PMP), specifically whether it would lead to improved clinical outcomes and reduced health care costs in a real-world clinical setting.

Background: Across Nepal, anesthesia at a district level is provided mostly by non-doctor anesthesia providers (anesthesia assistants-AAs). Nepal's Government recognized the need to sustain competence with continuous professional development and to upgrade 6-month trained working AAs to professional equivalence with the new national standard of 12-month training. As they are essential district health workers and AA clinical training sites are full, an innovative distance blended learning, competency-based, upgrade 1-year course was developed and conducted in 2014-2017 for two batches.

The high cost and energy intensity of virgin carbon fiber manufacture provides an opportunity to recover substantial value from carbon fiber reinforced plastic wastes. In this study, we assess the life cycle environmental implications of recovering carbon fiber and producing composite materials as substitutes for conventional and proposed lightweight materials in automotive applications (e.g.

We report the construction and use of a vortex reactor which uses a rapidly rotating cylinder to generate Taylor vortices for continuous flow thermal and photochemical reactions. The reactor is designed to operate under conditions required for vortex generation. The flow pattern of the vortices has been represented using computational fluid dynamics, and the presence of the vortices can be easily visualized by observing streams of bubbles within the reactor.

Background: To meet the need for essential surgery across rural Nepal, anesthesia at district level is delivered by nondoctor anesthetists. They require support to maintain confidence and competence, and upgraded professional registration to secure their status. To meet these needs, a distance-blended learning course was pioneered and delivered.

Background: Immediately placed/immediately restored dental implants in the esthetic zone are judged by not only their functional success but also the appearance and acceptance of the restorative outcome. The purpose of this study was to retrospectively evaluate in a private-practice setting the satisfaction of both patients and doctors regarding immediately placed/immediately restored implants in the esthetic zone.

Methods: The author group consists of nine board-certified periodontists.

Aim: To compare the effectiveness of two-ridge preservation treatments.

Materials And Methods: Forty subjects with extraction sockets exhibiting substantial buccal dehiscences were enrolled and randomized across 10 standardized centres. Treatments were demineralized allograft plus reconstituted and cross-linked collagen membrane (DFDBA + RECXC) or deproteinized bovine bone mineral with collagen plus native, bilayer collagen membrane (DBBMC + NBCM).

Supercapacitors are widely used in electric and hybrid vehicles, wind farm and low-power equipment due to their high specific power density and huge number of charge-discharge cycles. Waste supercapacitors should be recycled according to EU directive 2002/96/EC on waste electric and electronic equipment. This paper describes a recycling approach for end-of-life supercapacitors based on shredding and mild thermal treatment.

The traditional group practice model can take many forms, including general practitioners, specialists, and combinations, as well as solo practitioners sharing space and staff, partnerships, and other legal entities. These practices may share some or all staff functions, including contracting for some functions. The essential characteristic is that those treating patients also have full control over and often direct management of the business aspects of the practice.
