Radon is by far the largest contributor to population exposure because the dose received from radon and its progeny exceeds all other radiation sources. After smoking, it is the second most frequent cause of the lung cancer, therefore it is classified as Group 1 carcinogenic to humans. The soil under a building is the major source of indoor radon. ...

In this paper, a comparative study of the total vertical electron content (VTEC) calculated using the IRI-2016 and NeQuick2 models were performed. The research was done for the days of maximum solar activity in 2019, with data from seven IGS GNNS stations in the region of the Balkan Peninsula. The results show that both models agree quite well with...

The paper discusses how the dispersed urban form of Banja Luka (Bosnia and Herzegovina) is related to the collective housing form that emerged during the 20th and 21st centuries. The morphological study resulted in the typological patterns of collective housing form based on the relationship between the house and open space and follows its transfor...

Mobile Laser Scanning (MLS) is a technique characterized by high data acquisition efficiency and level of detail. However, a lot of information contained in the LiDAR point cloud is only implicitly available. Therefore, in order to create a digital topographic map from a large quantity of MLS survey data, it is necessary to define a methodology tha...

It is assumed that the porous material is based on the principle of conservation of mass and the principle of conservation of energy. The validity of both principles relies on experimental observations. Experimental results of different metals were used to compare the Poisson ratio as a function of porosity. A comparison is made between the theory ...
