Abstract: Mudflow is one of the natural disasters that frequently happen in Indonesia. This flow-type of landslide occurs suddenly and moves very fast, so it can cause massive damage and loss. However, knowledge about this disaster's behavior is minimal, even though it poses a huge destructive threat. Assessment from twenty case studies is done to understand more about mudflow behavior. High plasticity silt is the soil type most likely to become mudflow. The sediment concentration by volume value for mudflow is in the range of 0.29–0.56. Eight relationships between mudflow parameters were obtained: the steeper the slope, the greater the flow distance; as the liquidity index increases, the viscosity and yield stress value will decrease; the higher the viscosity, the greater the flow width; More volume moves from sources to deposition areas over longer flow distances; as flow rate increases, flow duration decreases; the deeper the flow depth, the shorter the flow duration. Lastly, a wider flow w

Abstract: The supply of heat to buildings in Romania and beyond is at a turning point and the main reason is the everincreasing price of fuel and electricity. In the current context, climate change, energy dependence, depletion of fossil fuel reserves and the current geopolitical context generated by the war between Ukraine and Russia are forcing national and European institutions, local and national authorities to be concerned with increasing the quality of life of citizens (or at least preserving it at its current level) and meeting the conditions for ensuring their comfort. Another important issue is the safe operation of heating systems and the provision of minimum indoor thermal comfort parameters. The long-term security of energy resources and the fight against climate change require measures for the introduction, modernisation and expansion of efficient heat supply systems. In order to achieve these objectives, conditions for the efficient use of energy resources must be developed and en
