Opis:
Due to interesting therapeutic properties of 177Lu and antineoblastic antibiotic, bleomycin (BLM), 177Lu-bleomycin (177Lu-BLM) was developed as a possible therapeutic compound. Lu-177 of 2.6-3 GBq/mg specific activity was obtained by irradiation of a natural Lu2O3 sample with a thermal neutron flux of 4 × 1013 nźcm-2źs-1. The product was converted into chloride form which was further used for labeling of BLM. In optimized conditions a radiochemical purity of 98% was obtained for 177Lu-BLM shown by instant thin-layer chromatography (ITLC) (specific activity, 740 GBq/mmole). Biodistribution studies of Lu-177 chloride and 177Lu-BLM were performed in wild-type rats. The accumulation of the radiolabeled compound in lungs, liver and spleen demonstrates a pattern similar to the other radiolabeled bleomycins. Lu-BLM is a possible therapeutic agent in human malignancies and the efficacy of the compound should be tested in various tumor-bearing models.

Opis:
Banking is a financial institution that has a very important role in economic and trade activities which is useful for channeling funds in the form of loans to the public who need fresh funds for business in the hope of helping to improve the people's economy. In the loan process, banks are often exposed to risks known as credit risk or non-performing loans. Therefore, a credit analysis is performed by estimating the parameters using LU Decomposition in the Logistic Regression model. In this paper, the data used are data about cooperative financial services in Indonesia. Variables taken in the study are including the age of debtors (X1), family dependents (X2), the amount of savings (X3), the value of collateral (X4), the amount of income per month (X5), given the credit limit (X6), take home pay (X7), and the loan term (X8).

Opis:
Ligament reconstruction is one of the surgical methods for treatment of anterior cruciate ligament injury. The main purpose of rehabilitation after surgical ligament reconstruction is to obtain maximal efficiency of knee joint, their stability and appropriate lower limbs encumbrance. Static posturography is one of the control, rehabilitative and diagnostic tools in such treatment. The purpose of the study was to evaluate the posture stability differences between healthy people and patients after anterior cruciate ligament reconstruction. The centre of pressure sway was registered using the standard posturography platform (Pro-med). During the test, the subject stood freely with eyes open and closed. In order to determine the stability of the subject, the average velocity of the centre of pressure sway, and the average accretion rate of surface area encircled by centre of pressure, a mean radius of centre of pressure and amount of its displacement were calculated. Parameters measured for the eyes closed posture were significantly greater for people after anterior cruciate ligament reconstruction, while differences between groups for eyes open test were statistically insignificant. This indicates impairment of the somatosensoric posture control system. It should be noted that selected stability indicators: an average velocity of the centre of pressure sway, its anterior-posterior and mediolateral components, a mean radius of centre of pressure and a mean accretion rate of surface area encircled by centre of pressure varied in both groups.

Opis:
Mediterranean regions have experienced significant soil degradation over the past decades. In this context, careful land observation using satellite data is crucial for understanding the long-term usage patterns of natural resources and facilitating their sustainable management to monitor and evaluate the potential degradation. Given the environmental and political interest on this problem, there is urgent need for a centralized repository and mechanism to share geospatial data, information and maps of land change. Geospatial data collecting is one of the most important task for many users because there are significant barriers in accessing and using data. This limit could be overcome by implementing a WebGIS through a combination of existing free and open source software for geographic information systems (FOSS4G). In this paper we preliminary discuss methods for collecting raster data in a geodatabase by processing open multi-temporal and multi-scale satellite data aimed at retrieving indicators for land degradation phenomenon (i.e. land cover/land use analysis, vegetation indices, trend analysis, etc.). Then we describe a methodology for designing a WebGIS framework in order to disseminate information through maps for territory monitoring. Basic WebGIS functions were extended with the help of POSTGIS database and OpenLayers libraries. Geoserver was customized to set up and enhance the website functions developing various advanced queries using PostgreSQL and innovative tools to carry out efficiently multi-layer overlay analysis. The end-product is a simple system that provides the opportunity not only to consult interactively but also download processed remote sensing data.

Opis:
Vacant frequency bands are used in cognitive radio (CR) by incorporating the spectrum sensing (SS) technique. Spectrum sharing plays a central role in ensuring the effectiveness of CR applications. Therefore, a new multi-stage detector for robust signal and spectrum sensing applications is introduced here. Initially, the sampled signal is subjected to SNR estimation by using a convolutional neural network (CNN). Next, the detection strategy is selected in accordance with the predicted SNR levels of the received signal. Energy detector (ED) and singular value-based detector (SVD) are the solutions utilized in the event of high SNR, whilst refined non-negative matrix factorization (MNMF) is employed in the case of low SNR. CNN weights are chosen via the Levy updated sea lion optimization (LU-SLNO) algorithm inspired by the traditional sea lion optimization (SLNO) approach. Finally, the outcomes of the selected detectors are added, offering a precise decision on spectrum tenancy and existence of the signal.

Opis:
Holmium, erbium and lutetium citrates can be synthesized by transforming freshly precipitated holmium, erbium and lutetium hydroxides in the citric acid solution under the hydrothermal conditions (above 100 ℃) after 3 days of reaction. In this paper in order to determine the synthesis conditions, the hydroxide and citrate stability areas of selected lanthanides were compared. The studies of the structure of the obtained holmium citrate, erbium and lutetium samples showed that these compounds crystallize in a monoclinic system. The crystallite sizes determined by the HalderWagner method were 67.8 ± 8.0nm, 103.7 ± 4.5nm and 68.1 ± 4.2nm, respectively for the holmium citrate, erbium citrate and lutetium citrate samples. The shifts of the hydroxyl and carboxyl groups of citric acid in the FTIR spectrum indicate the interactions of both groups with holmium, erbium and lutetium cations. Then the obtained samples were subjected to the analysis of composition, and their particle size distribution was determined.

The article intends to analyse the short story Lu scïò by Roman writer Guido Milanesi, published after the First World War in the collection of stories Mar Sanguigno. Milanesi’s works belong to the genre of the colonial novel, but Milanesi can be mostly defined as a writer of sea tales. The article introduces the historical period in which Milanesi’s works were published and then presents the Adriatic legend of the waterspout and compares it with other local writings. A brief linguistic analysis follows, which examines the mixture of Italian dialect and maritime terms present in the story.
L’articolo presenta brevemente il periodo in cui Guido Milanesi scriveva racconti di mare che si differenziano da quelli del successivo periodo caratterizzato invece dal romanzo di stampo coloniale. Successivamente si passa all’analisi del racconto Lu scïò, leggenda adriatica, prima introducendone la trama, poi spiegando l’origine e il significato di tale fenomeno. In seguito se ne cercano riscontri nella letteratura locale. Infine si propone una breve analisi linguistica, analizzando i termini dialettali e marinari presenti nel racconto.

Opis:
During the existence of the Polish People’s Republic (1944–1989), the dominant ideology was that of Marxism-Leninism. It wielded strong influence on the official world-view. The ideology aspired to explain, in reality, all phenomena and processes. However, wi- thin a short period of time it became apparent that Marxism-Leninism had its weaknes- ses, for example, developing the sciences was conditional upon their non-interference with the objects of Marxism-Leninism. One such science that fell in this arena was the cybernetics of law. Hence, the purpose of this article is to give a short presentation of ge- neral assumptions and relation between the cybernetics of law and Marxism-Leninism during the period of “real socialism” in the Polish People’s Republic.

Opis:
Artykuł przedstawia Deborę Vogel (1900–1942) jako jedną z najważniejszych krytyczek i teoretyczek sztuki lat trzydziestych XX wieku. Po polsku oraz w jidysz stworzyła ona system, w którym sztuka jawi się jako poetycko-programowa reakcja na rzeczywistość. Jest ona elitarna, ale też ściśle związana z codziennością. Jest niezbędna dla życia, ale też jest „samym życiem”, w sensie banalnej i wiecznej ballady. Za tą konstrukcją myślową kryje się malarstwo Marca Chagalla. To na przykładzie jego obrazów Vogel dowodzi głównej tezy awangardy o jedności formy i treści. Na tożsamość życia i sztuki Vogel spogląda przez pryzmat aktualności rozumianej nie jako manifestowanie poglądów politycznych, lecz jako konstruowanie rzeczywistości w dziele sztuki. Punktem wyjścia jest dla lwowskiej intelektualistki estetyka Hegla, od której stopniowo przesuwa się ku dialektyce materialistycznej, rozwijając m. in. tezy Lu Märten, pionierki estetyki marksistowskiej. Poetyka życia oraz koncepcje sztuki były u Vogel szeroko zakorzenione w filozofii, m.in. w teorii subiektywnego postrzegania Jakoba von Uexkülla. W artykule omówiona zostaje jego koncepcja koła funkcjonalnego, jak i mająca duży wpływ na artystów awangardowych teza, iż rzeczywistość stanowi dla indywiduum wyłącznie konstrukcję własnych doznań zmysłowych. Na koniec stawiane są pytania dotyczące znaczenia myśli Bergsona i Simmla dla rozumienia sztuki w ujęciu proponowanym przez Deborę Vogel.
In this article, Debora Vogel (1900–1942) is depicted as one of the most important art critics and theorists of the 1930s. In Polish as well as in Yiddish she designed a set of ideas both elitist and, at the same time, most tightly related to everyday-life in which art was considered essential to life and „life” itself – in the sense of a banal and eternal ballad. Behind this thought we see, quite substantially, the art of Marc Chagall. His paintings served Vogel as proof of the main thesis of avant-gardism that content equals form. The equal status of life and art is researched by Vogel through the lens of up-to-dateness – something she comprehended as a construction of reality in her work, not as an art manifesto or an expression of political views. Starting from Hegel’s aesthetics, the Lemberg-based intellectual moved on to materialist dialectics and became a follower of Lu Märten, the pioneer of Marxist aesthetics. Vogel’s poetics of life and her conceptions of art were versatile, rooted in philosophy, i.a. in Jakob von Uexküll’s theory of subjective perception. The latter’s conception of a functional circle contributing to a turn in the perception of the avant-garde, is reviewed in the article. Finally, several questions are put forth referring to the relevance of Henri Bergson’s and Georg Simmel’s thoughts for Vogel’s comprehension of art.

Opis:
In the first months of 1971 the Government of the Polish People’s Republic decided to start talks with the Holy See on the normalization of relations between the State and the Catholic Church. The intention of the Holy See was to achieve recognition of the legal personality of the Church in Poland. The only result achieved however was the will to continue negotiations in the future.Under the Protocol signed by the parties in July 1974, the communist authorities immediately appointed the head of their Team of representatives and began to reside in Rome. The decision to send a permanent representative of the Holy See to Warsaw was first made by Pope Paul VI in 1976 and upheld by John Paul I. After the pontificate began by John Paul II, the position of the Holy See in this matter was modified and as a consequence no delegate of the Pope was sent to the end of the seventies of the last century to Warsaw and no agreement was reached. At every stage of the negotiations that were carried without any representative of Polish Church. Cardinal Stefan Wyszyński, as the Head of the Conference of the Episcopate of Poland, was kept informed about their course and he supported the negotiators by submitting systematically in writing the opinion of the Conference of the Polish Episcopate to the Pope Paul VI, to Pope John Paul II as well as and for the Archbishop Agostino Casaroli. All suggestions and remarks were very valuable and supportive in negotiations due to the fact that they were originated by Polish bishops who knew well the internal situation in the country as well as the way of proceedings of communist authorities.
