Double Gloving: A Risk Reduction Strategy

The Joint Commission Journal on Quality and Safety, 2003
The use of sterile surgical gloves has become the international standard of care in the perioperative environment. Yet the potential for barrier failure exists, with the subsequent potential for the transfer of pathogens to both the patient and the surgical team.

Optimal filter reduction via a double projection

IEEE Transactions on Signal Processing, 2000
It is known that in many applications there arises the need of reducing the filter order. Solutions have been given for single or multiple variables cases by the use of orthogonal projection. The digital system under attention (multivariable case) is of order \(n\) (the order of the matrix \(A)\) \[ x(k+1)= A\cdot x (k)+B\cdot x(k),\quad y(k)=C\cdot x ...

Mechanism of Enzymatic Reduction of Steroid Double Bonds

European Journal of Biochemistry, 1973
The rate‐limiting step in the enzymatic reduction of double bonds in some steroids was studied with the aid of deuterated water and NADPH labeled in the A‐and B‐position with deuterium. The following reactions were studied: conversion of progesterone into 5α‐pregnane‐3, 20‐dione, catalyzed by rat liver microsomes; conversion of progesterone into 5β ...

“There is Demand, There is a Market”: Implementation of the Prohibitive Chinese Double Reduction Shadow Education Policy—From the Tutors’ Perspective

International Journal of Educational Reform
Amidst the growing prominence of shadow education (known as supplementary tutoring) in China and the implementation of the Double Reduction Policy (prohibiting academic tutoring for compulsory schooling stage students), this study presents a ...

Double Reduction of Plastoquinone to Plastoquinol in Photosystem 1

Biochemistry, 2011
In Photosystem 1 (PS1), phylloquinone (PhQ) acts as a secondary electron acceptor from chlorophyll ec(3) and also as an electron donor to the iron-sulfur cluster F(X). PS1 possesses two virtually equivalent branches of electron transfer (ET) cofactors from P(700) to F(X), and the lifetime of the semiquinone intermediate displays biphasic kinetics ...

Foreign English teachers’ intercultural reactions to China's “Double Reduction” policy

World Englishes
The Chinese government's 2021 “Double Reduction” policy decimated the online language tutoring industry. Beyond erasing billions of dollars of value, hundreds of thousands of foreign‐based online English teachers lost their jobs as a result of the policy.

A Critical Discourse Problematization Framework (CDPF) analysis of “Double Reduction” policy in China

Policy Futures in Education
This paper examines the “Double Reduction” policy issued by the Chinese government in 2021 by using a Critical Discourse Problematization Framework (CDPF) that combines Critical Discourse Analysis (CDA) and what’s the problem represented to be (WPR ...

An integrated reduction technique for a double precision accumulator

Proceedings of the Third International Workshop on High-Performance Reconfigurable Computing Technology and Applications, 2009
The accumulation operation, An+1 = An + X, is perhaps one of the most fundamental and widely-used operations in numerical mathematics and digital signal processing. However, designing double-precision floating-point accumulators presents a unique set of challenges: double-precision addition is usually deeply pipelined and without special micro ...

THE DOUBLE REDUCTIVE AMINATION APPROACH TO THE SYNTHESIS OF POLYHYDROXYPIPERIDINES

Targets in Heterocyclic Systems, 2019
As a consequence of their inhibitory activity towards a number of carbohydrate-processing enzymes, polyhydroxypiperidines constitute lead compounds for the development of new therapeutic agents in a wide range of diseases. The double reductive amination (DRA) reaction on dicarbonyl compounds represents a straightforward tool to efficiently access the ...

Double reductions/analysis of the Drinfeld–Sokolov–Wilson equation

Applied Mathematics and Computation, 2013
The authors study the following Drinfeld-Sokolov-Wilson system of nonlinear partial differential equations: \[ \begin{cases} u_t + 2vv_x = 0;\\v_t- av_{xxx} + 3bu_xv + 3kuv_x = 0. \end{cases} \tag{1} \] It is shown that the recently developed formulation of the association between symmetries and conservation laws lead to double reductions of the system
