Opis:: A problem of wave identification is formulated. We propose a diagnostic analysis of medium disturbances based on distinguishing of components of a wave vector that is specific for each kind of the wave mode. Mathematically it is realized by projection operator technique. An example is considered in conditions of a one-dimensional Cauchy problem for a conventional wave equation in the matrix form and its version with weakly x-dependent coefficients as a demonstration of the method application for the simplest adiabatic theory of one-dimensional acoustics. The case of acoustics in a gas with a dissipation account is also discussed from the point of view of the wave and entropy mode diagnostics.

Opis:: W artykule omówiono problematykę zewnętrznej instalacji odgromowej instalowanej na budynkach zabytkowych, w których znajdują się urządzenia elektroniczne. Ochrona obiektu polega na wyposażeniu go w wewnętrzną instalację odgromową, która będzie obejmowała również instalacje radiowe na zewnątrz budynku oraz pełne zabezpieczenie wszystkich urządzeń elektronicznych zainstalowanych wewnątrz obiektu po stronie zasilania. Jako przykład wymieniono stacjonarne obiekty kolejowe. Opisano najistotniejsze źródło zaburzeń elektromagnetycznych w postaci wyładowań atmosferycznych oraz zagrożenie pożarowe, jakie jest związane z tego rodzaju zjawiskiem. Przedstawiono elementy składowe zewnętrznej instalacji odgromowej oraz zasady jej doboru. Opisano sposób projektowania zewnętrznej instalacji odgromowej w odniesieniu do obowiązujących norm. Uwzględniono również problem ochrony obiektów przed pożarami powstałymi w wyniku wyładowań atmosferycznych.
In this article discusses the problem of designing external lightning protection is installed on the monumental buildings, which are electronic equipment. The structure.s protection consists in the equipment of the external earthling installation, which also includes the radio installations outside the buildings, and the full protection of all electronic equipment installed inside the structure, both on the side of the power supply. As an example of railways stationary objects. Describes the most important source of electromagnetic disturbances in the form of lightning and a fire danger, which is associated with this type of phenomenon. Presents the components of external lightning protection, systems and rules for its selection. Describes how to design the outer lightning protection systems for existing standards. Account is also the problem of protection of buildings against fire, engendered by lightning.

Opis:: A brief review of the evolution of denudation research since the 1960s is followed by a review of specific sediment yield variability in mountainous regions of the world as a function of spatial scale, relief, glaciation, lithology and disturbance type and location within the basin. A general model of scalar relations of suspended sediment yield for Canadian regions warns against comparing data from basins with areas ranging over several orders of magnitude. A regional summary of specific sediment yield in mountainous British Columbia confirms that in basins <1 km2 and >30,000 km2 specific sediment yield decreases with basin size whereas in basins of intermediate size (between 1 km˛ and 30,000 km˛) specific sediment yield increases with basin size. This effect is interpreted in terms of three distinct process zones in every mountain basin. These zones can be characterized as a) generally degrading hillslope zones, b) generally aggrading footslopes and valley sides, and c) channelized flows on valley floors demonstrating either net aggradation or degradation. These are identifiable repeating elements in such landscapes. Suspended sediment yield data from mountainous regions around the world are considered in light of the British Columbia model. Some support for the model is found where basins are stratified according to scale, relief, lithology, disturbance types, and location within each basin. Disturbance types include the presence of glaciers, land use activities of various kinds, such as increasing population pressure in the intertropical montane zone, changing population distribution and associated economic activities in the temperate montane zone, and potentially hydroclimate change.

Opis:: In the literary recollections of camp survivors the figure of the Muselmann is a recurring motif. The author puts forward a thesis about the existence of a dominating, prototypical narration about a Muselmann, which occurs not only in literary texts but also in scholarly studies. The questioning of the exemplary forms of depicting a Muselmann may lead to irritation and evoke in readers the feeling of “disturbance”. The re-enactment of such disturbances possesses a hidden analytical potential, as it reveals routinized and partly problematic cultural structures of reception and cquisition apparent especially in the context of post-catastrophic narrations and remembrance of the Shoah.

Opis:: The LQR (linear quadratic regulator) control problem subject to singular system constitutes a optimization problem in which one must be find an optimal control that satisfy the singular system and simultaneously to optimize the quadratic objective functional. In this paper we establish a sufficient condition to obtain the optimal control of discounted LQR optimization problem subject to disturbanced singular system where the disturbance is time varying. The considered problem is solved by transforming the discounted LQR control problem subject to disturbanced singular system into the normal LQR control problem. Some available results in literatures of the normal LQR control problem be used to find the sufficient conditions for the existence of the optimal control for discounted LQR control problem subject to disturbanced singular system. The final result of this paper is in the form a method to find the optimal control of discounted LQR optimization problem subject to disturbanced singular system. The result shows that the disturbance is vanish with the passage of time.

Opis:: This publication is devoted to the issue of pre-diagnosis and its role in the early detection of problems/delays/disharmony or developmental disorders in children at this age. Preschool diagnosis, supported by observation, as it is often the first study, on the basis of which the regularity or irregularity of a child’s development can be stated. It is the duty of teachers in relation to the results of this diagnosis, to take action to support the development of a child diagnosed with problems / delays / disharmony and disorder in order to reduce them. Early diagnosis and, consequently, early action enable one to avoid deepening the problems/disorders/disharmony or delays, and allows the child to function in the family and society.

Opis:: This paper presents 18 species of fungi that are new to the Kampinos National Park and their buffer zone. Seventeen of these species were found during studies on wind-damaged areas after the forest was damaged in 2017. One species new to Poland has been described and illustrated (Odonticium septocystidiatum). A few of the species recorded (Ciliolarina cfr. laricina, Daldinia petriniae, Pseudovalsa umbonata, Spongipellis litschaueri) are very rare in Poland and hitherto mentioned from single localities in the country. Two species from the Polish red list of macrofungi were recorded in the Kampinos National Park for the first time – namely, Punctularia strigosozonata (E) and Trichaptum biforme (R). The current number of macromycete taxa known from Kampinos National Park has reached a total of 1,630.
