Changes in polyamine content are related to low temperature resistance in potato plants

Acta Biológica Colombiana, 1999
Polyamine content and variation within a 48 hour simulated freezing stress were determined in plants with different low temperature resistance. Genotypes Solanum acaule, Solanum phureja, transgenic Solanum tuberosum c.v.

Universal restrictions to the conversion of heat into work derived from the analysis of the Nernst theorem as a uniform limit

, 2003
We revisit the relationship between the Nernst theorem and the Kelvin-Planck statement of the second law. We propose that the exchange of entropy uniformly vanishes as the temperature goes to zero. The analysis of this assumption shows that is equivalent

Magnetic field dependence of the density of states in the multiband superconductor $\beta$-Bi$_2$Pd [PDF]

, 2015
We present very low temperature scanning tunneling microscopy (STM) experiments on single crystalline samples of the superconductor $\beta$-Bi$_2$Pd. We find a single fully isotropic superconducting gap.

Scanning microscopies of superconductors at very low temperatures

, 2012
We discuss basics of scanning tunneling microscopy and spectroscopy (STM/S) of the superconducting state with normal and superconducting tips. We present a new method to measure the local variations in the Andreev reflection amplitude between a ...

Magnetismo topológico a bajas temperaturas

, 2018
Los dispositivos superconductores de interferencia cuántica o SQUIDs (del inglés, Superconducting Quantum Interference Devices) son unos de los dispositivos más famosos en electrónica superconductora. Combinan el efecto Josephson con el fenómeno de cuantización del flujo magnético en un anillo superconductor, lo cual da lugar a una de las ...
