PANTA RHEI OCZAMI HYDROLOGA, CZYLI JAK CYSTERSKA STRICZA STAŁA SIĘ WSPÓŁCZESNĄ STRZYŻĄ
PublicationArtykuł stanowi porównanie odpływu ze zlewni Potoku Strzyża w latach 1933 i 2016. W ciągu ostatnich osiemdziesięciu lat intensywnej urbanizacji naturalne pokrycie zlewni zastąpiły liczne powierzchnie nieprzepuszczalne. Antropopresja ograniczyła retencję powierzchniową, proces infiltracji i przepływ podziemny. Ponadto zmianie uległa naturalna sieć drenażu zlewni. Ryzyko powodzi w Gdańsku wzrosło na skutek zwiększonej objętości odpływu...

Zero-range potentials for Dirac particles: Bound-state problems
PublicationA model in which a massive Dirac particle in $\mathbb{R}^{3}$ is bound by $N\geqslant1$ spatially distributed zero-range potentials is presented. Interactions between the particle and the potentials are modeled by subjecting a particle's bispinor wave function to certain limiting conditions at the potential centers. Each of these conditions is parametrized by a $2\times2$ Hermitian matrix (or, equivalently, a real scalar and a...
