Polar Temperatures and Coal Measures

Nature, 1923
I THANK Mr. Bonacina for his sympathetic comment in NATURE of September 22, p. 436, on my letter on “Polar Temperatures and Coal Measures” and for the added clarity he has brought to this subject. He mentions disagreement with me on one minor issue only, and that relating to the south polar regions.

Polarization characteristic of a room-temperature Co:MgF_2 laser

Applied Optics, 2002
A study of the polarization characteristic of a Co:MgF2 laser with a 1320-nm YAG pumping laser at room temperature is reported. The thresholds, output energies, and efficiencies of the laser are given at the various polarization states. The more intensive emission is in the pi-polarization pump laser and sigma-polarization laser operation. Performances

Temperatures in Polar Ice Caps

Nature, 1959
DECREASE in temperature with depth which was first observed by Sorge1 in the top 20 m. of ice at Eismitte in Greenland has since been confirmed for much deeper strata there2,3 and in Antarctica4,5. Sorge thought that the negative temperature gradient could have been created by a secular rise in air temperature.

Polarization-induced pairing in high-temperature superconductivity

Physical Review B, 1987
We propose a mechanism for the pairing of electrons at the copper sites on the spin of quasi-one-dimensional Cu-O chains induced by the electronic polarization of the oxygen atoms in the side chains. We use a model Hamiltonian for a cluster of Cu-O chains and calculate the various correlation functions for a wide range of parameters.

The Temperature Dependence of the Polarizing Effect

Japanese Journal of Applied Physics, 1985
The results of the measurement of temperature dependence of the resonant frequency change caused by the application of the dc electric field to the piezoelectric resonators prepared from a Bi12GeO20 crystal are given in the paper. The temperature coefficient of the nonlinear piezoelectric coefficient is calculated from the measured values.

Temperature Polarization Coefficient (TPC)

2012
In all membrane distillation (MD) configurations, the mass and heat transfer takes place simultaneously. In the process the water vapor is transferred through a porous hydrophobic membrane. In order to achieve evaporation of water at the membrane-liquid interface, the heat has to be supplied from the warm feed.

Temperature and Polarization Studies of the Cosmic Microwave Background

2010
The cosmic microwave background (CMB) provides us with a wealth of information about the properties of our Universe. In this PhD work, we develop and apply new techniques for studying fundamental problems of cosmology using the CMB. Dark energy, if it exists, leaves a characteristic imprint in the CMB temperature fluctuations, the so-called integrated ...
