An alternative method of rapid-cycle PCR for DNA amplification is demonstrated using electrolyte resistance for heating and temperature monitoring. The PCR amplification solution is electrically conductive and can be heated by passing an alternating current through the sample. The temperature of the solution is evaluated by monitoring its electrical resistance. Cooling is accomplished by forced...

The Monte Carlo code for the physically correct tracing of photons in cloudy atmospheres (MYSTIC) three-dimensional radiative transfer model was used in a parametric study to determine the strength of longwave radiative heating and cooling in atmospheres enclosed in idealized valleys and basins. The parameters investigated included valley or basin shape, width, and near-surface temperature cont...

I study non-radiative cooling of X-ray emitting gas via heat conduction along magnetic field lines inside magnetic flux loops in cooling flow clusters of galaxies. I find that such heat conduction can reduce the fraction of energy radiated in the X-ray band by a factor of ∼ 1.5− 2. This non-radiative cooling joins two other proposed non-radiative cooling processes, which can be more efficient. ...

1. Hand heat elimination was measured during central body heating or cooling to evaluate the sensitivity of thermoregulation in patients exhibiting Raynaud’s Phenomenon. 2. Patients with Raynaud’s Phenomenon responded to central heating and cooling very much as did normal subjects. 3. Patients with Raynaud’s Phenomenon and associated connective tissue disease do not vasodilate in the hand in re...

This paper presents a stable, nonlinear, adaptive control scheme for building heating and cooling systems. The proposed controller utilizes the principle of adaptive one step ahead control and aims at reducing the energy consumed for heating or cooling a building. The design steps are discussed in details and a proof of global stability is also provided. Also, the performance of the proposed co...

We measure feedback (heating rates) in damped Lyα systems (DLAs) from the cooling rate of the neutral gas. Since cooling occurs through [C II] 158 μm emission, we infer cooling from C II 1335.7 absorption lines detected with HIRES on the Keck I telescope. The inferred heating rates are 30 times lower than for the Galaxy ISM. At z ≈ 2.8 the implied star formation rate per unit area is logψ∗=−2.4...

The effect of local and whole-body heating and cooling on plasma fibrinolytic activity has been investigated in 59 subjects. An increase in whole-body temperature and both local cooling and heating increased the fibrinolytic activity. The results demonstrate that the application of local heat or cold will produce a local increase in fibrinolytic activity which is independent of general factors ...

Seven freshwater turtles Trachemys scripta were instrumented with flow probes and cannulated for blood pressure measurements. The turtles were warmed from 24 to 34 degrees C, and cooled down to 24 degrees C, with and without atropine. Animals exhibited a hysteresis of heart rate and blood flow to both the pulmonary and systemic circulations, which was not cholinergically mediated. Blood pressur...

Abstract The US government has set a target of reducing CO2 emissions by 20% below the 2005 targets by the year 2020. Literature review reveals that residential buildings contribute over 20% of the total emissions mainly used for space heating, cooling, water heating and lighting. In hot humid climates, the concern is mainly for cooling and hot water that account for over 50% of the total resid...

Thermoelectric effects allow the generation of electrical power from waste heat and the electrical control of cooling and heating. Remarkably, these effects are also highly sensitive to the asymmetry in the density of states around the Fermi energy and can therefore be exploited as probes of distortions in the electronic structure at the nanoscale. Here we consider two-dimensional graphene as a...
