Opis:
In 2015, the Ministry of Health of the Republic of Poland introduced the Polish strategic plan for radiotherapy development and investment. Given that radiotherapy utilisation depends on the distance a patient must travel to undergo the treatment, the main goal of the plan was to increase equitable access to radiotherapy in Poland by establishing new facilities in new locations by 2025. This study constitutes the first step towards an economic evaluation of this plan by adopting spatial interaction models to project the expected increase in the demand for radiotherapy (3%). Moreover, it adds to the current research on the relation between distance and demand for healthcare services in the following ways. First, it flags the importance of using spatial econometrics to healthcare utilisation studies in the presence of spatial autocorrelation. Furthermore, it proposes a quantitative method for assessing the expected impact of establishing new facilities on utilisation. Finally, it formally confirms the dependence between radiotherapy utilisation and distance in Poland, which has been previously shown to exist in other countries.

Opis:
A new law of gravitation is established for continuous media, which establishes the correspondence of the sign of force to the density gradient of matter. Conditions are found under which it becomes the law of gravitation of Newton. The new law predicts the observed character of the rotation curves of galaxies, the existence of "strong" gravity and gravitational equilibrium. The data of recent astronomical observations confirming the presence of gravitational forces of attraction and repulsion are given.

Opis:
A new nonlocal discrete model of cluster coagulation and fragmentation is proposed. In the model the spatial structure of the processes is taken into account: the clusters may coalesce at a distance between their centers and may diffuse in the physical space Ω. The model is expressed in terms of an infinite system of integro-differential bilinear equations. We prove that some results known in the spatially homogeneous case can be extended to the nonlocal model. In contrast to the corresponding local models the analysis can be carried out in the $L_1(Ω)$ setting. Our purpose is to study global (in time) existence, mass conservation and well-posedness of the model.

Opis:
Vessels moored at port terminals may be subject to excessive strain on mooring lines, induced by other ships passing in their vicinity. This phenomenon is called hydrodynamic interaction, and well known in the international literature as Passing Ship. It occurs due to the displacement of the mass of water between the two vessels, which, consequently, induces hydrodynamic stresses on the two ships. Within this context, scale models are a powerful tool for hydrodynamics studies, being able of reproduce the complex water flow phenomena that take place around passing and moored ship. This paper presents a scale model technique to study the Passing Ship phenomenon and its application on a case study developed for the Santos Port. The study was based on the analysis of the results of simulations performed on a 1:170 scale model to compare the effect of various navigations conditions on the mooring lines of a docked ship.

Opis:
The article deals with the most important results of the grant research into interpersonal relations in young offenders institutes. The young offenders institutes are resocializing and reeducational establishments for maladaptive children and teenagers. In these institutes the research was done into relations between management workers and educators, relations among the educators themselves, relations between educators and wards and the attitudes of staff to the interpersonal behaviour. Information on results gained mostly by standardized methods are rather illustrative in the article. The main emphasis is put on the results of the so called non-structured participative observation. Students of the resocialization branch of counselling examined the communication of the pedagogical workers as well as the wards during the period of 4-10 weeks in 10 different institutes. The article informs mainly about the communication between management workers and educators and also between educators and wards.

Opis:
W doświadczalnictwie rolniczym kluczową kwestią są serie doświadczeń odmianowych, stanowiące szczególny przypadek doświadczeń dwuczynnikowych, w których jednym czynnikiem są odmiany, a drugim miejscowości. Do opisu charakteru interakcji dwóch czynników, a więc w powyżej opisanym przypadku, mogą być stosowane wielowymiarowe modele statystyczne takie jak model AMMI, GGE czy JREG. Praca ta ma przybliżyć możliwości zastosowania wybranych modeli statystycznych ze szczególnym uwzględnieniem modelu AMMI. Oprócz analizy AMMI przedstawiono uzupełniającą analizę skupień. Opisane metody statystyczne są celowe w analizie reakcji odmian roślin rolniczych na warunki środowiskowe, czyli agroekosystemy, na podstawie danych z serii doświadczeń.
Series of cultivar trials are a key issue in agricultural experimentation. They represent a specific case of two-factorial experiments, where cultivars are one factor and locations are the other one. Multivariate statistical models like AMMI, GGE or JREG are used to describe type of interaction between the factors. The paper is aimed at showing possibilities of application of some statistical models, with particular emphasis put on the AMMI model. Additionally, supplementary cluster analysis is presented. The described statistical methods are a suitable tool in analysis of response of crop cultivars to environmental conditions, based on data from series of trials.
