Opis:
This text shows the transformations which have taken place in the theological and canonical understanding of Christian witness on the occasion of the beatification and canonization process of Father Maximilian Maria Kolbe. These transformations concerned the understanding of who a Christian witness is in light of his life and his moment of death as well as – in the case of a martyr – the general makeup of the individual who acts as a persecutor. The beatification and canonization process of Father Kolbe have led to the discovery of how refined the twentieth century totalitarian systems’ persecution of Christians has become. This, in turn, has led to new situations, where particular cases of sanctity discussed in the canonical process have gone beyond already existing canonical norms.

Opis:
The increase of financial risk that has been observed for more than three decades has brought about the necessity of using new financial solutions increasing the efficiency of protection from the results of unexpected and disadvantageous events. A response to the investors’ new needs was a dynamic development of the market of derivative instruments, including options. Since investing in options, because of the financial lever, is highly risky, their pricing becomes a particularly significant issue. The article presents basic, most often applied mathematical models used for defining the value of stock call and put options. They include: the binomial model connected with the names of John Cox, Stephen Ross and Mark Rubinstein, the Black-Scholes model and the Merton model. In the case of the binomial model two approaches are presented that make it possible to assess the value of options – the one typical of the assumption concerning universal indifference to risk, and the one based on the method of option replication. According to the Black-Scholes model the price of options is the function of such factors as: the underlying price, the strike price, the time to expiration, the risk-free interest rate, and the volatility of the underlying asset. The Merton model, that is the most popular modification of the Black-Scholes formula, extends it to the case of options run for the shares of the companies constantly paying dividends.

Opis:
Remote controlled laboratories had a great push during the COVID-19 pandemic. In fact, they were already out there but lacking in visibility. This external trigger pushed the academy to face a global challenge to start offering remote experiments more consistently and maturely. Instituto Superior Técnico (IST) has been offering several remote experiments since 2000 but with the need for an update due to technological aging. As such, the framework for remote experiments in education (FREE) was created based on new web technologies. In addition to the most diverse experiments that had already been developed, FREE includes two experiments that aimed at advanced-level physics students: the Langmuir probe and the electromagnetic (EM) cavity. Both allow users to configure the various parameters and to access the results in real time or check back later. All this access is done using a browser (on a PC or mobile phone) without the need to install additional software. The results of an experimental execution are stored in a database and are downloadable, allowing users to do various analyses and to determine the corresponding plasma density and temperature. In this paper, we will introduce how FREE was used in the implementation of both experiments and give an insight into their didactic approach, such as: (i) how to perform an experimental execution, (ii) the typical data set obtained with, and (iii) the corresponding analysis necessary for the user to retrieve information from it.

Opis:
Płytkie wody podziemne są szczególnie podatne na zanieczyszczenie azotanami pochodzenia rolniczego. W pracy podjęto próbę rozpoznania kierunku przestrzennych i czasowych zmian stężenia azotanów w płytkich wodach gruntowych, zalegających pod warstwą piaszczystej gleby, w miejscu okresowego składowiska obornika i w jego najbliższym otoczeniu. Badania przeprowadzono w latach 2009–2015 na terenie gospodarstwa rolnego ukierunkowanego na produkcję mleka, położonego w północno-zachodniej części środkowego basenu Biebrzy, w województwie podlaskim. Stanowisko badawcze zlokalizowano na skraju pola, na którym corocznie uprawiano kukurydzę i gdzie na przełomie lat 2010/2011 i 2014/2015 okresowo składowano obornik. Próbki wód gruntowych pobierano korzystając z 7 studzienek kontrolno-pomiarowych, w odstępach miesięcznych, 4-8 razy w roku. Uzyskane zbiory wyników zawartości azotanów poddano analizie statystycznej z wykorzystaniem analizy wariancji z testem Kruskala-Wallisa. Przeprowadzono również analizę korelacji stężenia azotu azotanowego w wodzie z różnych punktów badawczych oraz analizę jego regresji w kolejnych latach badań. Średnie, roczne stężenie azotu azotanowego w próbkach wód gruntowych pobieranych z poszczególnych studzienek kształtowało się szerokim zakresie wartości od 1,1 do 101,8 mg N-NO3∙dm–3. W zdecydowanej większości przypadków (86%) wielokrotnie przekraczało ono graniczną wartość dla III klasy jakości wód podziemnych czyli 11,3 mg N-NO3∙dm–3. Zatem badane wody należy zaliczyć do wód zanieczyszczonych bądź zagrożonych zanieczyszczeniem. Ponad to w ujęciu przestrzennym i czasowym, średnie, roczne zawartości azotanów w badanych próbach wód gruntowych, pobieranych ze studzienek zainstalowanych na terenie stanowiska badawczego charakteryzowały się znacznym zróżnicowanym przestrzennym, miały odmienne nasilenie jak też kierunki zmian w czasie, w niewielkim stopniu były ze sobą skorelowanie.
Shallow groundwater is particularly susceptible to contamination by nitrates from agricultural sources. The paper attempts to recognize the direction of spatial and temporal changes in the concentration of nitrates in shallow groundwater, lying under a layer of sandy soil, in the place of a temporary manure storage place and in its immediate vicinity. The study was conducted in the years 2009–2015 on farm focused on milk production, located in the north-western part of the central basin of Biebrza, in Podlaskie voivodeship . The research stand was located at the edge of the field where maize was grown every year and where manure was periodically stored at the turn of 2010/2011 and 2014/2015. Groundwater samples were collected using 7 control and measurement wells, on a monthly basis, 4-8 times a year. The obtained results of nitrates content were subjected to statistical analysis using the analysis of variance with the Kruskal-Wallis test. The analysis of correlation of nitrate nitrogen concentration in water from various research points and analysis of its regression in subsequent years of research was also performed. The average annual concentration of nitrate nitrogen in groundwater samples collected from individual wells was in the wide range from 1.1 to 101.8 mg NO3∙dm–3. In the vast majority of cases (86%) it repeatedly exceeded the limit value for the third class of groundwater quality, or 11.3 mg N-NO3∙dm–3. Thus, the tested water should be classified as polluted or at risk of contamination. In addition, in spatial and temporal terms, the average annual nitrates content in the tested groundwater samples collected from wells installed on the research site was characterized by a significant different spatial, has a different intensity as well as directions of changes in time, to a small extent correlated with each other.

Opis:
Within Futurism, a critical concept is formed of the past, of history in general, and of the way in which history is lived in the present, along with its harmful consequences, as it becomes an excuse to avoid progress by constantly looking back at the past. This is an idea that is exemplified well by Giovanni Papini in his Discorso di Roma. Contro Roma e contro Benedetto Croce. However, the past and history as “sickness” had already been analysed by Friedrich Nietzsche in On the Use and Abuse of History for Life. In the early years of the 20 th century, the German philosopher established his presence within Italian culture thanks to the authors of the literary journal Leonardo, and Papini in particular. These intellectuals not only wrote about Nietzsche in their magazine, but they also tried to make use of Nietzche’s thought. From a Futurist perspective, the connection between the two authors has to do primarily with the criticism of history and the past. However, the Röcken-born philosopher focuses on both the abuse and use of the historical past, while Papini carries this idea to extremes by stressing only the abuse that comes from it, therefore condemning it tout court. By doing this, the Tuscan intellectual, shortly after adhering to Futurism, follows the guidelines imposed by the avant-garde movement and expresses the fiery magnitude of his thought, aimed at the destruction of the past in all its forms to make way for the long-denied future.
All’interno del Futurismo si sviluppa tutta una concezione critica del passato e della storia in genere e di come essa viene vissuta nel presente, i suoi effetti deleteri, il pretesto per non progredire mai guardandosi sempre alle spalle. Esemplare di questa concezione l’approccio di Giovanni Papini analizzato attraverso il suo Discorso di Roma. Contro Roma e contro Benedetto Croce. Il passato, la storia come “malattia” erano stati trattati precedentemente da Friedrich Nietzsche in Sull’utilità e il danno della storia per la vita. Agli albori del ’900, il filosofo tedesco si afferma nella cultura italiana grazie agli intellettuali “leonardiani”, in particolar modo Papini. Questi, oltre a parlarne sulle colonne della rivista, cercarono di far funzionare nelle proprie menti il pensiero di Nietzsche. In ottica futurista, il legame fra i due verte principalmente sulla critica della storia e del passato. Tuttavia, il filosofo di Rocken si sofferma sul danno e sull’utilità del passato storico, mentre Papini estremizza tale concezione, ponendo l’accento esclusivamente sui danni da essa prodotti, spendendosi nella sua condanna tout court. In questo modo, l’intellettuale toscano appena approdato al Futurismo, uniformemente alle linee guida dettate dall’avanguardia, sprigiona tutta la portata incendiaria del proprio pensiero volto alla distruzione del passato in ogni sua forma, per schiudere le porte al futuro da esso negato.

Opis:
The paper deals with a new fuzzy version of the Lee-Carter (LC) mortality model, in which mortality rates as well as parameters of the LC model are treated as triangular fuzzy numbers. As a starting point, the fuzzy Koissi-Shapiro (KS) approach is recalled. Based on this approach, a new fuzzy mortality model - CNMM - is formulated using orthonormal expansions of the inverse exponential membership functions of the model components. The paper includes numerical findings based on a case study with the use of the new mortality model compared to the results obtained with the standard LC model.
