Solid water is often the phantom material of choice for dosimetry procedures in radiotherapy high-energy X-ray and electron beam radiation calibration and quality assurance. This note investigates variation in heat conduction that can occur for a common commercially available solid water stack phantom when a temperature differential occurs between the phantom and ambient temperature. These vari...

Slow-heating pyrolysis experiments of 14 plant species native to forests in the southern United States were conducted a TGA find kinetic parameters for slow all live and air-dried samples. Kinetic coefficients determined from data using model-fitting methods, resulting single entire process which can be used by wildland fire modelers. The model forms explored here are simple one-step multiple r...

Six cases of multiple sclerosis are reported in which cold produced a temporary exacerbation of symptoms and signs of the disease. Also, in one case investigated in detail by psychophysical methods, heating produced a paradoxical deterioration in vision and simultaneous improvement in sensory and motor function. The effect of temperature in multiple sclerosis is discussed and a physiological ex...

A generalization of a recently developed MHD model of a proposed heating mechanism for the middle chromosphere is presented. The generalization consists of including the ideal gas equation of state, allowing the temperature to vary with position, and allowing the hydrogen flow velocity to vary with height in a specified manner. These generalizations allow for a self consistent calculation of a ...

Cellulose, chitin and chitosan are the most abundant biopolymer on earth and constitute an important class of biodegradable materials. The decomposition of three major biopolymers viz. chitin, chitosan and cellulose are studied using simultaneous thermal analysis i.e. thermogravimetry/differential thermal analyzer (TG/DTA). Thermal analysis is performed from ambient temperature to 700 °C in a f...

The processes νe +n ⇋ e− + p and ν̄e + p ⇋ e +n provide the dominant mechanisms for heating and cooling the material below the stalled shock in a core-collapse supernova. We summarize the major effects of strong magnetic fields on the rates of the above reactions and illustrate these effects with a simple supernova model. Due to parity violation of weak interaction the heating rates are asymmetr...

Until recently traditional heating in organic chemistry has been done with oil heating baths or using electric heat exchangers. With the advent of microwave equipment, heating by microwaves was rapidly introduced as standard method in organic chemistry laboratories, mainly because of the convenient possibility to operate at high temperature accompanied by accelerated reaction rates. In the pres...

The proposed Mars Science Laboratory (MSL) mission is intended to deliver a large rover to the Martian surface within 10 km of the target site. This paper presents computational fluid dynamics (CFD) predictions of forebody heating rates for two MSL entry configurations with fixed aerodynamic trim tabs. Results are compared to heating on a 70-deg sphere-cone reference geometry. All three heatshi...

We present an ion trap with integrated fiber cavity, designed for strong coupling at the level of single ions and photons. The cavity is aligned to axis a miniature linear Paul trap, enabling simultaneous multiple field. simulate how charges on mirrors affect potential, we test these predictions trapped in cavity. Furthermore, measure micromotion heating rates setup.
