Ocena wybranych własności fizykochemicznych wód na przykładzie wyników pomiarów z ZUW i stacji SANEPID
(2008)The chosen parameters of water that determine its usefulness for drinking and economic purposes are presented in this article. The chosen examples of water usefulness take into account the following parameters: colour ... -
Rozważania na temat możliwości wpływu efektu cieplarnianego na zmianę parametrów klimatycznych atmosfery
(2008)While discussing the global situation of Earth’s natural environment and changes in the physical characteristics of atmosphere which cause climate change, the most frequently mentioned is the greenhouse effect. The ... -
Koncepcja i wyniki badań eksperymentalnych filtru objętościowego wielowarstwowego
(2008)Experimental research shows that dry air filters based on filter paper are marked by a considerable change of characteristics, progressing with time of operation. With a stable air-stream flowing through the filter, there ... -
Stopy magnezu dla przemysłu motoryzacyjnego
(2008)The automotive industry shows an interest in magnesium alloys due to the necessity to reduce weight of car components, and thereby to improve fuel economy and reduce $CO_2$ emission. The aim of this paper is to provide ... -
Bezradność nauczycieli techniki i informatyki wobec zagrożeń szkolnych
(2008)The article shows the problem of insufficient preparation of graduates to work as teacherseducators; in schools, they face many problems connected with pupils’ violence against peers and teachers. The article shows the ... -
Zastosowanie popiołu lotnego ze spalania węgla kamiennego jako osnowy ziarnowej mas formierskich utwardzanych chemicznie
(2008)The article presents the physicochemical, structural and textural proprieties of the fly-ash and the fly-ash after the pressure agglomeration. The obtained agglomerate was used as grain of moulding sands with the hydrated ... -

Boundary value problem and functional equations for overlapping disks
(2007)We compare applications of the method of functional equations to boundary value problem for circular multiply connected domains and to circular polygons generated by overlapping disks. The second part of the paper is devoted ... -
Submaximal Riemann-Roch expected curves and symplectic packing
(2007)We study Riemann–Roch expected curves on $P^1 × P^1$ in the context of the Nagata–Biran conjecture. This conjecture predicts that for a sufficiently large number of points multiple points Seshadri constants of an ample ... -
Iterative roots of homeomorphisms possessing periodic points
(2007)In this paper we give necessary and sufficient conditions for the existence of orientation-preserving iterative roots of a homeomorphism with a nonempty set of periodic points. We also give a construction method for these roots. -
On sets associated to conditional equation of exponential function
(2007)In the present paper we give a description and properties of the system of cones over Q which are one of parameters determining the solutions of the conditional equation of exponential function.
