There is no argument that the mind extends
(2011)On the basis of two argumentative examples plus their ‘parity principle’, Andy Clark and David Chalmers argue that mental states like beliefs can extend into the environment. I raise two problems for the argument. The first ... -
Thermal analysis in phase change materials (PCMs) embedded with metal foams
(American Society of Mechanical Engineers (ASME), 2010)The heat transfer enhancement for phase change materials (PCMs) has received increasing attention nowadays, since most of PCMs have low thermal conductivities which prolong the charging and discharging processes. Metal ... -
Thermal analysis of girth welded joints of dissimilar metals in clad pipes : Experimental and numerical analysis
(Society of Petroleum Engineers, 2017-01-01)Welding of two dissimilar materials was carried out in-house with the aid of a Tungsten Arc weld with dynamic measurement of temperature profiles in the vicinity areas of the welding track using high temperature thermocouples. ... -
Thermal analysis of Phase Change Material Board (PCMB) under weather conditions in the summer
(2016-04-25)Phase Change Material Board (PCMB) has been considered as an effective way to improve the thermal comfort in either new or existing buildings. In this work, firstly the optimal melting temperatures of internal and external ... -
Thermal and exergetic analysis of Metal Foam-enhanced Cascaded Thermal Energy Storage (MF-CTES)
(2013-03)Metal Foam-enhanced Cascaded Thermal Energy Storage (MF-CTES) has been proposed to solve the problem of poor heat transfer during heat exchange process, which is caused by unavoidable decrease of temperature differences. ... -
The thermal and nonthermal effects of high and low doses of pulsed short wave therapy (PSWT)
(2010)The study aimed to investigate the thermal and non-thermal effects of pulsed short wave therapy (PSWT) using high and low dose of PSWT together with placebo and control conditions in healthy subjects. Method. A single–blind, ... -
Thermal and structural characterization of acrylonitrile butadiene styrene (ABS) copolymer blended with polytetrafluoroethylene (PTFE) particulate composite
(2019-06-05)Anovel thermally sustainable polymer composite was fabricated with Acrylonitrile Butadiene Styrene (ABS) as the matrix and Polytetrafluroethylene (PTFE) particle as the filler, using injection molding process with 10 and ... -
Thermal build-up, decay and retention responses to local therapeutic application of 448 kHz capacitive resistive monopolar radiofrequency : A prospective randomised crossover study in healthy adults
(2015-11-17)PURPOSE: Radiofrequency-based electrophysical agents are widely used in therapy-related clinical practice for their thermal effects, mainly relieving pain and inflammation and improving tissue extensibility. The most ... -
Thermal conductivity measurement of porous silicon by the pulsed-photothermal method
(2011-09-07)Thermal properties of two types of porous silicon are studied using the pulsed-photothermal method (PPT). This method is based on a pulsed-laser source in the nanosecond regime. A 1D analytical model is coupled with the ... -
Thermal cycling and ageing of a glass-ceramic sealant for planar SOFCs
(2011-09)Thermal cycling and thermal ageing tests were performed on Crofer22APU/glass-ceramic/Anode-Supported-Electrolyte (ASE) joined samples in air at the SOFC operating temperature of 800 degrees C. The Crofer22APU had been ... -
Thermal cycling of Crofer22APU-sealant-anode supported electrolyte joined structures for planar SOFCs up to 3000 h
(2013)Thermal cyclic tests in air were performed for Crofer22APU/glass-ceramic/ Anode-Supported-Electrolyte (ASE) joined samples for a total period of 3000 h. Different cooling rates from the SOFC operating temperature of 800 C ... -
A thermal desorption method for determining atmospheric Semi-Volatile Organic Compound concentrations
(University of Hertfordshire, 2007)It is now recognised that indoor environments contribute significantly to human exposure to airborne pollutants. People spend a large amount of time in indoor environments and there are many indoor sources that are not ... -
Thermal diffusivity of Ni–Ti SMAs
(2009)In this paper thermal diffusivity dependence on temperature of NiTi SMAs alloy in the range from 300 K up to 1500 K is reported and the experimental–numerical approach adopted for this scope is described. The experimental ... -
Thermal Effect of Cylindrical Heat Sink on Heat Management in LED Applications
(2022-10-14)Light Emitting Diode (LED) applications are increasingly used in various microelectronic devices due to their efficient light generation. The miniaturisation of the LED and its integration into compact devices within the ... -
Thermal Feedback in the High-mass Star- and Cluster-forming Region W51
(2017-06-16)High-mass stars have generally been assumed to accrete most of their mass while already contracted onto the main sequence, but this hypothesis has not been observationally tested. We present ALMA observations of a 3 × 1.5 ... -
Thermal IR radiative properties of mixed mineral dust and biomass aerosol during SAMUM-2
