The “work-regenerative” effect in centreless grinding
International Journal of Machine Tool Design and Research, 1965Abstract The problem of work-regenerative waviness encountered in centreless grinding is discussed with respect to the dynamic characteristics of the machine and the effect of the geometrical configuration of the workpiece in the system of the grinding operation.

The Effects of EDTA on Blood Clot in Regenerative Endodontic Procedures
Journal of Endodontics, 2019In regenerative endodontic procedures (REPs), a blood clot acts as a natural scaffold for regenerating dental pulp tissue. In current protocols, 17% EDTA is recommended for liberating growth factors from root dentin. Although EDTA affects clot formation in periodontal studies, the anticoagulant effect of EDTA has not been shown in REPs. Therefore, this

The regenerative effects of electromagnetic field on spinal cord injury
Electromagnetic Biology and Medicine, 2016Traumatic spinal cord injury (SCI) is typically the result of direct mechanical impact to the spine, leading to fracture and/or dislocation of the vertebrae along with damage to the surrounding soft tissues. Injury to the spinal cord results in disruption of axonal transmission of signals.

Regenerative effects in the Sit-to-Stand and Stand-to-Sit movement
Robotica, 2014SUMMARYWhile Sit-to-Stand and Stand-to-Sit are routine activities and are crucial pre-requisites to walking and running their underlying dynamics are poorly understood. Furthermore, the potential for using these movements to regenerate energy in energy-sensitive devices such as orthoses, prostheses and humanoid robots has never been examined.

The Effect of Microstructure of Octacalcium Phosphate on the Bone Regenerative Property
Tissue Engineering Part A, 2009The present study was designed to investigate whether the microstructure of synthetic octacalcium phosphate (OCP) affects its intrinsic bone regenerative properties as a scaffold and its conversion process into hydroxyapatite (HA).

Journal of Entrepreneurship in Emerging Economies, 2022
Purpose Exposure to a public health threat of significant proportions made current models inadequate to explain the failure phenomenon in small businesses. Hence, the need to reimagine the phenomenon. Borrowing from the principles of biology, this study extended theoretical and empirical perspectives on the failure phenomenon by unpacking its ...

Gandhi’s Spinning Wheel: The Charkha and Its Regenerative Effects
Journal of the History of Ideas, 2020This essay interrogates the role of the charkha (spinning wheel) in Mohandas Gandhi's thought. It argues that spinning deserves to be recognized as belonging in the realm of other high concepts and practices, such as non-violence, that have garnered much more academic attention.

In Vivo Evaluation of Cartilage Regenerative Effects of CCN2 Protein
2016CCN family protein 2/connective tissue growth factor (CCN2/CTGF) is a unique growth factor that promotes the proliferation and differentiation, but not the hypertrophy of articular chondrocytes in vitro. Based on these findings, we previously evaluated the cartilage-regenerative effects of recombinant CCN2 protein (rCCN2) by using both mono-iodoacetate

Effect of regenerative load on a static transfer switch performance
IEEE Transactions on Power Delivery, 2001A thyristor-based static transfer switch (STS) is used to connect an alternate source of ac power to a sensitive load when the main source fails. A main criterion for performance evaluation of an STS is the transfer time from the main to the alternate source.

On the effective sampling time of regenerative comparators
2008 51st Midwest Symposium on Circuits and Systems, 2008A practical regenerative comparator will be modeled as a comparator with ideal sampling accuracy preceded by a time-windowing function. An analysis of the regenerative comparator will be presented resulting in an expression for the windowing function in terms of the time constants of the comparator.
