TL;DR: In this article, the isobaric heat capacity of liquid HFC-134a, which is a prospective alternative to CFC-12, has been measured by using a flow calorimeter.
Abstract: The isobaric heat capacity, C p , of liquid HFC-134a, which is a prospective alternative to CFC-12, has been measured by using a flow calorimeter. The C p of saturated liquid, C p ', has been determined on the basis of the data measured in the compressed liquid phase, and a correlation of C p ' has also been developed

TL;DR: In this article, a differential scanning calorimeter based on the heat leak principle has been proposed, with a reference measuring cell and a sample measuring cell symetrically seated within a copper heat sink, where a plurality of resistive heating elements are applied to the several surfaces of the heat sink and the isothermal shield, each heating element having a resistance proportional to the heat capacity of the surface to which it is applied.
Abstract: A differential scanning calorimeter based on the heat leak principle having a reference measuring cell and a sample measuring cell symetrically seated within a copper heat sink. Each measuring cell (10) includes a cylindrical stainless steel ampoule (12) which contains a test substance, a honeycombed aluminum cell frame (14) which supports the ampoule, and a pair of thermopiles (18) which are placed between the aluminum cell frame and the copper heat sink (16) and which measure the temperature difference between the two. The copper heat sink is surrounded by a cylindrical copper isothermal shield (20). A plurality of resistive heating elements (146-150) are applied to the several surfaces of the heat sink and the isothermal shield, each heating element having a resistance proportional to the heat capacity of the surface to which it is applied. The heating elements are wired electrically in series. A common current is then passed through the heating elements. Note The International Application refers to drawings which in fact, were not included in the application at the time of filing. Drawings were submitted after the expiration of the time limit prescribed in Rule 20.2 (a) (iii), accordingly, and reference to the said drawings shall be considered non existent under Article 14 (2).

TL;DR: In this paper, the construction and beam test results of the ATLAS electromagnetic end-cap calorimeter pre-production module 0 are presented, and a global constant term of 0.6% is obtained in the pseudorapidity range 2.5 eta 3.2 (inner wheel).
Abstract: The construction and beam test results of the ATLAS electromagnetic end-cap calorimeter pre-production module 0 are presented. The stochastic term of the energy resolution is between 10% GeV^1/2 and 12.5% GeV^1/2 over the full pseudorapidity range. Position and angular resolutions are found to be in agreement with simulation. A global constant term of 0.6% is obtained in the pseudorapidity range 2.5 eta 3.2 (inner wheel).
