Performance loss among workers due to heat stress in high-temperature workplaces

Background: Heat stress is one of the harmful factors present in many workplaces. It can lead to performance loss and low functionality of the labor force. Therefore, the aim of this study was to evaluate exposure to heat stress and its consequent performance loss among workers functioning in indoor high-temperature workplaces. Materials and Methods: This descriptive, analytical study was co...

Quantum oscillations and Fermi surface in an underdoped high temperature superconductor

Despite twenty years of research, the phase diagram of high-temperature superconductors remains enigmatic 1 , 2. A central question is: what makes the physical properties of these copper oxides so dramatically different on opposite sides of the superconducting region? In the overdoped regime, the material behaves as a reasonably conventional metal, with a large Fermi surface 3 , 4. The underdop...

Interaction-induced singular Fermi surface in a high-temperature oxypnictide superconductor

In the family of iron-based superconductors, LaFeAsO-type materials possess the simplest electronic structure due to their pronounced two-dimensionality. And yet they host superconductivity with the highest transition temperature Tc ≈ 55K. Early theoretical predictions of their electronic structure revealed multiple large circular portions of the Fermi surface with a very good geometrical overl...
