Consequences of the obesity epidemic on cancer morbidity and mortality are not fully appreciated. Obesity is a risk factor for many cancers, but the mechanisms by which it contributes to cancer development and patient outcome have yet to be fully elu

The molar enthalpy, ΔH, of hafnium (3 wt.% Zr) has been measured by levitation drop calorimetry for the solid β-phase in a temperature range from T=2096 to 2455 K and for the liquid phase from T=2339 to 2988 K. The temperatures of the α to β and

SUMMARY The issue of allowing the Liming, duration and magnitude of a flood release to be determined by man has led to a wide spectrum of viewpoints as to which values of these parameters are most suitable for the Pongolo River Floodplain, where the

Using electromagnetic levitation alloying calorimetry, the concentration and temperature dependence of the mixing enthalpy of liquid Ti–Ni and Fe–Ti–Ni alloys has been determined. For the Ti–Ni alloys, the measurements have been carried out a

The mixing enthalpies of liquid Ti-Zr, Fe-Ti-Zr and Fe-Ni-Zr alloys were measured by levitation alloying calorimetry. The mixing enthalpy of Ti-Zr alloys is slightly exothermic and symmetric with an extreme value of -5.2 kJ mol -1 , It can be describ

Investigations on measuring the activities and the mixing enthalpies of the Fe–Ni, Ni–Cr and Fe–Cr liquid binary systems show only weak negative deviations from ideal behaviour. Therefore, only small atomic interactions occur between the atoms

The mixing enthalpies of liquid binary iron-nickel, nickel-chromium and iron-chromium alloys were measured by levitation alloying calorimetry. The mixing enthalpy of iron-nickel alloys is asymmetric and was described by an equation according to the m

Electromagnetic levitated liquid cobalt was undercooled with the purpose to trigger solidification at desired temperatures. Triggering was performed at the underside of the sample. The solidification velocity was determined by detecting the trigger s
