Macroscopic expressions of molecular adiabatic compressibility of methyl and ethyl caprate under high pressure and high temperature
(Journal article; Peer reviewed, 2014)The molecular compressibility, which is a macroscopic quantity to reveal the microcompressibility by additivity of molecular constitutions, is considered as a fixed value for specific organic liquids. In this study, we ... -
Manure energy exploitation : the use of biogas to secure water supply in developing countries
(Master thesis, 2013)This thesis has investigated the feasibility to produce electricity for water pumping in developing countries by using a simple biogas reactor system with an internal combustion. This was done by visiting Katulani Secondary ... -
A married couple of mathematicians from Vienna remembers Sigmund Freud (1953)
(Peer reviewed; Journal article, 2023)The paper is based on a hitherto unexplored document (audiotape of an interview accompanied by a German transcript) from 1953, located in the Freud Papers at the Library of Congress. It contributes to a better understanding ... -
