Entrepreneur’s trust in banks in terms of behavioural economics
... article considers the issues of trust in banks in terms of the rationality of clients’ behavior and behavioural economy. The author’s empirical study of 370 owners of small and microfirms located in the Warmian-Masurian voivodeship suggests that approximately 69 % of the respondents prefer the services of Polish banks (or those dominated by Polish capital) and 10.1 % prefer banks with foreign capital. The rest of the respondents (20.9 %) have no particular opinion on the subject.

Semi-geodetic transformation of temporary images
Often while seismic data processing one gets time dependent images (time cuts, time migration), in which time plays the role of the «depth» variable. If in some approximation the wave propagation velocity is known, these images can be transformed into the true ones. In this article for this purpose it is proposed to use semi-geodesic transform associated with the normal to the boundary rays. The results of simulations ...
The modelling of postmortem heat transfer and estimating the time of death
... A model of heat transfer in a newborn cadaver presented as a finite cylinder is examined in detail. An important factor in constructing a mathematical model of postmortem heat transfer in a newborn aimed at identifying the time of death is body form approximation. It is shown that heat transfer in a cadaver is not sufficient for identifying the time of death, which should be based on a comprehensive assessment of postmortem changes.

Protection of steel from corrosion and hydrogen absorption by organic inhibitors: experimental and quantum-chemical studies
The step-strip anodic dissolution technique was used to obtain concentration profiles of cathodic evolved H2 across the depth of Cr-Ni1810 steel under corrosion in water-salt media in the presence of SRB. The proposed approximation of the experimentally obtained distribution of hydrogen along the depth of steel by means of standard Gaussian function made it possible to establish the integral hydrogen content of the sub-layer (up to 80 μm) with high degree of accuracy....
Filtration activity of mollusks Mya arenaria L. (Bivalvia) in estuaries of the southern Baltic Sea

A numerical assessment of the filtration rate of these molluscs shows that they can filter daily an average of 2.41 ± 1.01 m3 of water per a square meter of the river bed. During the vegetation season, molluscs can clear approximately 380 m3 of water in estuaries removing up to 558.9 ± 65.7 g of suspended organic matters.

A method to construct the projection operators for the Poincare and Rossby waves in the atmosphere
... which allows us to identify the contribution of certain types of waves in the observed wave field. This work presents a procedure for constructing the projection operators for the Poincare and Rossby planetary waves in the spherical atmosphere in the approximation of "shallow water". The proposed procedure allows to obtain the generalized form of the projection operator approach without the use of β-plane.
