Abstract: Use of a composition (A) having a pH of at least 8 at 25° C. containing at least 50 wt.-% x of water or a water containing solvent mixture, at least 0.1 mol/m3 of at least one water x soluble silicate, optionally at least one molybdate, optionally at least one phosphonate, optionally at least one azole, optionally at least one additional freezing point depressing salt, optionally at least one phosphate, and optionally at least one nitrate, as heat carrier medium for magnetocaloric materials of formula (I) (AyB1?y)2+uCwDxEz (I) where: A is Mn or Co, B is Fe, Cr or Ni, C is Ge, As or Si, D is different from C and is selected from P, B, Se, Ge, Ga, Si, Sn, N, As and Sb, E may be same or different from C and D and is selected from P, B, Se, Ge, Ga, Si, Sn, N, As and Sb.

Abstract: The invention relates to a gliding board including a structural beam defining a longitudinal direction and having a gliding surface bordered on each side with a lateral running edge, each running edge having an edge body and an anchoring blade, the anchoring blades of the two running edges being oriented opposite one another. An inextensible connecting element locally connects the anchoring blades, at least along a portion at least of the length of the beam, and the connecting element is oriented in the extension of each of the blades.
