Thermal, chemical, tensile and morphological characterization studies of bamboo fibre extracted from the indian species bambusa bambos
(2023-10-06)The objective of this research is to investigate the extraction and characterization of a particular kind of Indian bamboo family plant known as Bambusa bambos. The fibres were extracted from the bamboo plant in the form ... -
Thermodynamic Analysis and Algorithm Optimisation of a Multi-stage Compression Adiabatic Compressed Air Energy Storage System
(2020-06-15)In this article, a novel multi-stage compression and heat recovery on an adiabatic compressed air energy storage (A-CAES) system is proposed. In the current work, an in-house code named CAESSC 1.0 is successfully developed ... -
Thermodynamic analysis and comparison between CO2 transcritical power cycles and R245fa organic Rankine cycles for low grade heat to power energy conversion
(2016-08-05)In this paper, a theoretical study is conducted to investigate and compare the performance of CO2 transcritical power cycles (T-CO2) and R245fa organic Rankine cycles (ORCs) using low-grade thermal energy to produce useful ... -
Thermodynamic considerations of solvent/enhancer uptake into a model membrane
(2010-08-30)The aim of this study was to conduct a thermodynamic analysts of the uptake of solvents into a model membrane as a precursor to skin transport studies. The investigation was designed so that the methodology may be applied ... -
Thermogelling Materials for Topical Drug Delivery
(2021-02-26)This thesis describes the synthesis and characterisation of thermogelling materials and their evaluation as topical drug delivery excipients. Thermogelling materials are polymers which transition from solution to gel ... -
Thermohydraulic analysis of covalent and noncovalent functionalized graphene nanoplatelets in circular tube fitted with turbulators
(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
(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
(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
(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
(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
(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
(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.
(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
(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
(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
(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
(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 ... -
