The paper deals with the fundamental rule of extensional logics, namely the rule of Existential Generalization. This rule can be applied in the situation when a function f is applied on its argument a to obtain the value of f at a. If the application does not fail, i.e., if the function f is defined at a, then we can existentially quantify, and derive that there is the value f(a). Our system is based on Transparent Intensional Logic (TIL). Since TIL is a hyperintensional, partial, typed lambda calculus, we examine...

The thermal insulation of the building envelope is a very important factor for the total energy consumption of buildings. Considering the fact that more than 40% of the global energy use and the corresponding CO2 emissions comes from the building sector, the choice of good thermal insulation products can contribute to large energy savings. The choice of thermal insulation products should not be solely made based on installation and operational costs, but rather on the global environmental impact and energy demand ...

Latvia has been actively involved in reducing global climate change. However, since 2006, along with an increase in economic activity, greenhouse gas emissions (GHG) from LatviaпїЅs agricultural sector have tended to increase; besides, the agricultural sector is the second largest source of GHG emissions, in 2015 accounting for 24.2% of the total GHG emissions in the country. Such changes in GHG emissions from agriculture in Latvia indicate that without additional measures Latvia cannot reach its GHG emission targ...

In the northwestern Black Sea the Danube deep sea fan has an extent of over 150 km and stretches from several hundred meters water depth down to the abyssal plain at 2200 m water depth. This large turbiditic system comprises a series of channel-levee systems, with deposits of mass transport. Its evolution was due to the fluctuations of sea level and sediment inputs. Sedimentary and seismic facies identified on the Danube deep sea fan are similar to those that characterize most fans of this type. In the study area ...
