. Calorimetry, being a non specific technique, measures all events that occur during the process of seed germination either of physical or chemical nature. Calorimetry has proven to be useful as monitor for many types of physical, chemical or biological systems
Terpilowski et al. [ 9 ] and Cakir et al. [ 10 ], while Kleppa [ 11 ], Wittig et al. [ 12 ], and Yazawa et al. [ 13 ] expolored them using direct reaction calorimetry, and newest reference by Brunetti et al. [ 14 ]. Optimal thermodynamic activities for indium
that 1 °C increase in temperature between 20 and 25 °C produces 7% increase in respiration rate.
Calorimetry could be a suitable technique to measure CO 2 evolution from glucose amended soils. A method was developed to measure CO 2 evolution
Among all these measurements and uncertainty budgets, that of the adiabatic temperature rise stands out as being specific to this type of calorimetry and applicable to other measurements in this field. Therefore, a separate publication was decided. The
This personal review focuses on two aspects. First, glass transition dynamics and hence also calorimetry is connected to dynamic
heterogeneity. This results in an interplay of the corresponding dynamic length scales and length scales from structural heterogeneities
in polymeric samples. Second, the complexity of the dynamic glass transition itself results in different effects of this interplay
for different experimental observables. Hence the comparison of results from calorimetry with other relaxation methods gives
important clues to an understanding of the complex glass transition phenomenon.
The results of comparative thermodynamic analysis of AuIn–Sb section in ternary Au–In–Sb system are presented in this paper.
Investigation was carried out experimentally, using Oelsen calorimetry at the temperature 873 K and analytically, applying
different predicting methods––Toop and Muggianu in the temperature interval from 873 K to 1673 K. The values for integral
molar Gibbs excess energies and antimony activities have been determined and compared at temperature of 873 K, which indicated
to good agreement between experimental results and results obtained using Toop predicting model.
be monitored by isothermal (conduction) calorimetry and five stages can be distinguished, as mentioned by several researchers [ 1 , 2 ]: (i) the initial period; (ii) the induction period; (iii) the acceleration period; (iv) the deceleration period
The calorimetry exchange (CALEX) program is administered by New Brunswick Laboratory (NBL). The main objective of the program
is to provide an independent verification of the internal quality control practices in nuclear material safeguards facilities
making plutonium accountability measurements by non-destructive calorimetry/gamma spectrometry techniques. Facilities measure
the calorimetric power, and plutonium and 241Am isotope abundances of CALEX program standards using routine accountability procedures. The measurement results as well
as two other quantities (effective specific power and plutonium mass) calculated from these results are evaluated for accuracy
(or bias) and precision. In this paper, a limited number of measurement results of a CALEX program standard (identified as
Calex I) are evaluated with specific goals to identify a suitable method for uncertainty estimation and to identify the major
contributors to the uncertainties. In order to achieve the goals, the Calex I measurement results were evaluated using two
different methods: the first method confined to uncertainty estimation from random variations of the measurement results alone,
and the second method providing a more comprehensive evaluation of uncertainties from both the measurements and the characterized
values of the measured standard according to the Guide to the Expression of Uncertainty in Measurement (GUM). The results
of this study, and a subsequent study extended to a larger number of results in the CALEX program database, are expected to
provide relevant input for developing the International Target Values for plutonium measurements by the calorimetry/gamma

The European Symposium on Thermal Analysis and Calorimetry (ESTAC) owes it origins to a decision by the UK Thermal Methods Group (TMG) to hold an international meeting on thermal analysis in the UK, following a
