The power sources used in cutting arc torches are usually poorly stabilized and have a large ripple factor. The strong oscillatory components in the voltage and arc current produce in turn, large fluctuations in the plasma quantities. Experimental observations on…

Measurements have been made on the angular dependence of the magnetoresistance effect and the Hall effect on oriented w-type indium antimonide samples. The measurements were taken at room temperature and liquid air temperature using a magnetic field strength of about…

The observation of delayed proton emission is reported. Bombardment of both aluminum and silicon with 97-Mev protons leads to the emission of delayed proton energy groups from to 5 Mev. They follow the beta decay of S25 (T1/2 about 0.3…

Rotational energy levels of axially asymmetric nuclei have been calculated in the manner of Davydov and Filippov, and a comparison with experiment shows good quantitative agreement. It is suggested that agreement may be improved by introducing the Bohr-Mottelson vibration-rotation interaction…

This study analyzes data and information of the physical and chemical characteristics of water, and type of sediments of the continental shelf of the Gulf of Tehuantepec, Mexico. The changes of salinity, temperature, and dissolved oxygen fluctuate according to the…

Measurements of the spin-spin relaxation time and of the effective, lattice-induced, transition probabilities are reported for magnetically dilute potassium chromicyanide in chemically analyzed concentrations ranging nfrom 0.06 to 1.5%. In these measurements the c-axis of the cobalticyanide matrix was parallel…

The Faculty of Medicine at University of Castilla-La Mancha (UCLM) started in 1998 an innovative method of teaching and learning. Students are divided into groups of 25 people maximum, and they are told to teach their classmates all concepts suggested…
