Municipal waste generated by hospitality has become a significant sustainability challenge for tourist destinations. Ambitious sectoral actions to mitigate waste generation will require changes in the hospitality businesses' internal operations combi

El síndrome de Down es causado por la presencia de una tercera copia del cromosoma 21 y fue descrito por primera vez en 1838 por Jean-Etienne-Dominique, y más tarde por John Langdon Haydon Down en 1866, mientras trabajaba como superintendente me

Adiabatic calorimetry measurements have been performed on Cs2CdBr4 from 90 to 270 K. Phase transitions at 252.03, 237.02, and 154.88 K were found. The thermal expansion coefficients and the elastic constant values were used to separate the harmonic a

The specific heat of N(CH3)4MnBr3 has been measured by adiabatic calorimetry, using both static and dynamic methods. The obtained results have permitted the calorimetric characterization of the phase transition which the crystal shows at 143 K. The c

Some examples of calorimetric measurements in several crystals containing at least one tetramethylammonium unit in compounds of (N(CH3)4)2BX4 and (N(CH3)4)BX3 families are presented. They show the possibilities of using adiabatic calorimetry in the p

The structural phase transitions in were investigated by means of adiabatic calorimetry and thermal expansion measurements. Two phase transitions have been studied on cooling and on heating at about 104 K and 118 K. The shapes of the observed specifi

Calorimetric measurements of Cs2ZnI4 showed four distinct phase transitions at 117, 108, 104 and 94 K. The shape of the observed specific heat peaks indicates that those at 108 and 94 K are first order in nature. This sequence is in agreement with pr

We study the optical response of a strongly anisotropic nonmagnetic material. As a first case, it is considered an anisotropic nonmagnetic thin film (medium 2) sandwiched between medium 1 of refraction index n1 and medium 3 of refraction index n3. As
