Thermohydraulic analysis of covalent and noncovalent functionalized graphene nanoplatelets in circular tube fitted with turbulators

Tao, Hai; Alawi, Omer A.; Hussein, Omar A.; Ahmed, Waqar; Abdelrazek, Ali H.; Homod, Raad Z.; Eltaweel, Mahmoud; Falah, Mayadah W.; Al-Ansari, Nadhir; Yaseen, Zaher Mundher (2022-10-21)

Covalent and non-covalent nanofluids were tested inside a circular tube fitted with twisted tape inserts with 45° and 90° helix angles. Reynolds number was 7000 ≤ Re ≤ 17,000, and thermophysical properties were assessed ...

Thermonuclear Ti-42(p, gamma)V-43 rate in type-I x-ray bursts

He, J. J.; Parikh, A.; Brown, B. A.; Rauscher, T.; Hou, S. Q.; Zhang, Y. H.; Zhou, X. H.; Xu, H. S. (2014-03-05)

The thermonuclear rate of the Ti-42(p, gamma)V-43 reaction has been reevaluated based on a recent precise proton separation energy measurement of S-p(V-43) = 83 +/- 43 keV. The astrophysical impact of our new rates has ...

Thermophysiological responses to capacitive resistive monopolar radiofrequency electromagnetic radiation in patients with osteoarthritis of the knee joint: a randomised controlled experimental study

Kumaran, Binoy; Watson, Tim (2020-11-11)

This study investigated the effect of 448 kHz capacitive resistive monopolar radiofrequency (CRMRF) on the superficial and deep physiological responses of patients with osteoarthritis (OA) of the knee(s). Forty-five patients ...

Thermoresponsive poly(di(ethylene glycol) methyl ether methacrylate)-ran-(polyethylene glycol methacrylate) graft copolymers exhibiting temperature-dependent rheology and self-assembly  

da Silva, Jéssica Bassi; Haddow, Peter; Bruschi, Marcos Luciano; Cook, Michael T. (2022-01-15)

Graft copolymers with brush-type architectures are explored containing poly (ethylene glycol) methacrylates copolymerized with “thermoresponsive” monomers which impart lower critical solution temperatures to the polymer. ...

Thermoresponsive systems composed of poloxamer 407 and HPMC or NaCMC: mechanical, rheological and sol-gel transition analysis

da Silva, Jéssica Bassi; Cook, Michael T.; Bruschi, Marcos Luciano (2020-04-15)

Poloxamer 407 (polox407) is widely studied as thermogelling polymer, transitioning to a gel state when warmed Polox407 forms weak hydrogels with rapid dissolution in excess solvent. This study reports the development of ...

Thermoresponsive Triblock‐Copolymers of Polyethylene Oxide and Polymethacrylates: Linking Chemistry, Nanoscale Morphology, and Rheological Properties

da Silva, Marcelo Alves; Haddow, Peter; Kirton, Stewart B.; McAuley, William J.; Porcar, Lionel; Dreiss, Cécile A.; Cook, Michael T. (2022-02-23)

Abstract: Thermoreversible gels switch from a free‐flowing liquid state to an elastic gel mesophase upon warming, displaying the reverse transition upon cooling. While this phenomenon makes these advanced materials highly ...

Thermoreversible gels for the encapsulation of macrophages: evaluation of polymer type on rheology and cytocompatibility

Zeqiri, E.; da Silva, M. A.; Aspinall, S. R.; Hoffman, E.; Hutter, V.; Cook, M. T. (2023-11-02)

Thermoresponsive polymers have become a highly sought-after “smart material” due to their ability to modify their physical characteristics due to temperature changes. This research aimed to determine the biocompatibility ...

‘They are called Imperfect men’: Male infertility and sexual health in early modern England.

Evans, Jennifer (2016-05-01)

Scholars of early modern gender and medicine have tended to focus on the female infertility. Discussions that have included male reproductive failure have considered sexual ability and impotence, rather than infertility. ...

'They are Exactly as Bank Notes are': Perceptions and Technologies of Bank Note Forgery During the Bank Restriction Period, 1797 - 1821

Mockford, Jack (University of Hertfordshire, 2014-12-10)

Previous studies of Bank Note forgery in England during the Bank Restriction Period have adopted a highly institutional focus. Thus, much is known about the role played by both the Bank of England and the workings of the ...

Thick Microporous Silicon Layers Etching Involving p(+)n Back Side Hole Injection in Highly Resistive n-Type Substrates

Coudron, Loic; Gautier, Gael; Morillon, Benjamin; Kouassi, Sebastien; Defforge, Thomas; Ventura, Laurent (2011)

Anodization studies on low-doped n-type silicon in aqueous electrolytes have systematically shown the formation of macropores. In this paper, we show the possibility to produce microporous silicon in low-doped n-type ...

The Thing of the Essay

Plunkett, Erin (Edinburgh University Press, 2022-10-31)

I read the essay’s attitude toward things as a commitment to both receptivity—lingering with things as they are found--and renewal—seeing new possibilities in things. Understanding the essay as an experiment in dwelling ...

THINGS: The HI Nearby Galaxy Survey

Walter, F.; Brinks, E.; de Blok, W.J.G.; Bigiel, F.; Kennicutt, R.C.; Thornley, M.D.; Leroy, A. (2008)

We present “The HI Nearby Galaxy Survey (THINGS)”, a high spectral (≤5.2 kms−1) and spatial (~ 6′′) resolution survey of HI emission in 34 nearby galaxies obtained using the NRAO Very Large Array (VLA). The overarching ...

'Think differently and be prepared to demonstrate trust' : findings from public hearings, England, on supporting lay people in public health roles

South, Jane; Meah, Angela; Branney, Peter E (2012)

Professional support processes are critical for the establishment and maintenance of community health worker programmes. This paper reports on three public hearings held in England, UK, that were conducted as part of a ...
