TL;DR: A simple calorimeter based on the measurement of oxygen uptake has been developed and it is shown that it can be used to measure the intensity of carbon dioxide uptake in the atmosphere.
Abstract: 1. A simple calorimeter based on the measurement of oxygen uptake has been developed. 2. A respiratory simulator was used to evaluate oxygen uptake at different flow rates. A known concentration of mixed gases flows into the calorimeter via the respiratory simulator. Oxygen concentration and flow rate were measured and stored to memory for further analysis. 3. Results indicate that large errors occur at low flow rates, but that the error is less than 5% under normal conditions. 4. This device can be used to measure oxygen uptake under resting conditions.

TL;DR: In this article, the lateral and longitudinal profiles of hadronic showers detected by a prototype of the ATLAS Iron-Scintillator Tile Hadron Calorimeter have been investigated.
Abstract: The lateral and longitudinal profiles of hadronic showers detected by a prototype of the ATLAS Iron-Scintillator Tile Hadron Calorimeter have been investigated. This calorimeter presents a unique longitudinal configuration of scintillator tiles. Using a fine-grained pion beam scan at 100 GeV, a detailed picture of transverse shower behaviour is obtained. The underlying radial energy densities for the four depth segments and for the entire calorimeter have been reconstructed. A three-dimensional hadronic shower parametrisation has been developed. The results presented here are useful for understanding the performance of iron-scintillator calorimeters, for developing fast simulations of hadronic showers, for many calorimetry problems requiring the integration of a shower energy deposition in a volume and for future calorimeters design.

TL;DR: In this article, a system of differential equations modeling a heat flux DSC is solved and the results are compared with those obtained using a TA Instruments Q1000™ DSC, and it is shown that the differences are the result of simplifications implicit in the conventional heat flow rate measurement that is based solely on the difference between sample and reference calorimeter temperatures.

TL;DR: In this paper, a static bomb combustion calorimeter was used to calculate the enthalpy of adamantane at 298.15 K and the standard enthalpys of formation ΔHof(C10H16,c) = -(45.02 ± 0.79) kcal mol−1.
