‘Wind, Wind, Wind, Always Winding Am I’: Dickens’s Metafictional Clockwork

open access: yesThe Review of English Studies, 2022
Abstract This article considers the importance of timepieces and clockwork to Dickens’s conception of composition. Whilst the many clocks and watches that saturate his writing have often been read as indicative of an interest in time, the present study considers what the materiality of timepieces—namely, their markets and mechanisms ...

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

GENERAL CALCULATION OF WINDING FACTOR FOR MULTI-PHASE/-LAYER ELECTRICAL MACHINES IRRESPECTIVE OF POLES NUMBER

open access: yesActa Polytechnica, 2019
In this paper, a method to calculate the winding factor by only considering stator parameters without the rotor ones is developed. This is interesting because it allows the separation of the stator and rotor design, unlike the existing methods in the ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Dynamic investigation of Georges phenomenon related to three-phase wound-rotor induction motor

open access: yesJournal of Electrical Systems and Information Technology, 2020
The aim of this paper is to analyze the performance of a three-phase wound-rotor induction motor (WRIM) under rotor windings asymmetry. The dynamic performance of the WRIM under healthy and rotor windings asymmetry with one-open-phase fault conditions is

Wind Winding Down [PDF]

open access: yesScience, 2011
Climate Science Increasing concentrations of greenhouse gases in the atmosphere, emitted by human activities, have caused Earth's climate to warm. Climate warming has been linked to a host of other environmental changes, one of the most evident being an increase in the amount of water present ...
