Abstract

Currently, the question is no longer if the climate is changing because the magnitude and speed of climate change, but it is a fact confirmed by many teams of specialists. It has become a hotly debated topic for politicians, businessmen, environmentalists, society and media. We designed a pilot study using a questionnaire in order to identify the level of knowledge, skills and practices of family physicians regarding the impact of their work on the environment and climate change. The questionnaire included 42 items regarding socio-demographic data, doctors’ knowledge regarding climate change, global warming, heatwave, thermal stress, the activity performed by doctors during the heat wave and the information received by doctors about heatwave periods. The research results confirm the hypothesis that doctors have some knowledge about the phenomenon of climate change, but there are some gaps and misunderstandings of the cause and effect of the phenomenon, as well as the methods to combat them. There is a need for additional training and guidance of physicians on the relationship between climate change, global warming and population health.

Abstract

The paper presents a part of the work conducted in the first stage of a Research Grant called ”Hybrid micro-cogeneration group of high efficiency equipped with an electronically assisted ORC” acronym GRUCOHYB. The hybrid micro-cogeneration group is equipped with a four stroke Diesel engine having a maximum power of 40 kW. A mathematical model of the internal combustion engine is presented. The mathematical model is developed based on the Laws of Thermodynamics and takes into account the real, irreversible processes. Based on the mathematical model a computation program was developed. The results obtained were compared with those provided by the Diesel engine manufacturer. Results show a very high correlation between the manufacturer’s data and the simulation results for an engine running at 100% load. Future developments could involve using an exergetic analysis to show the ability of the ORC to generate electricity from recovered heat
