Opis:
This article is devoted to one of the sermons by the great and illustrious Victorine preacher, Absalon of Sprinckirsbach (died 1205), author of the extensive collection Sermones festivales, which was first published in 1534 in Cologne, and was later reprinted in 1605 in Milan and in J.-P. Migne’s perennial Latin patrology. The sermon in question is the sermon XLI, one of four sermons by Absalon intended to be read or preached on the occasion of a church dedication ceremony – three of these occasional sermons are already available in Polish translation. A translation of the indicated work is offered here with brief commentaries in the form of footnotes to selected parts of it. The Latin text of the sermon is also included below, so that the two language versions, Latin and Polish, can be easily compared by the reader. The present work, which enriches the collection of those Victorine texts in which the allegorical meaning of the Christian temple is expounded and which are available in Polish, is an element of a broader research project, which will culminate in a study referring to Absalon’s theology of the house of God. This study will complement the article “Multa in his omnibus latent profunda mysteria.” Hugh, Richard and Adam of St Victor’s understanding of the church building.

Opis:
Increasing urbanization results in constant enlarging of the artificial area closed to water infiltration. In 2006–2008, the Soil Sealing Enhancement (SSE) database was the part of the GMES Fast Track Service on Land Monitoring. The accuracy of the final product set by the authors should reach at least 85%. Orthorectified high resolution aerial photos of Poland were used to develop reference data constituting 20,000 random samples around the country. In each sample, the points were classified into three possible surface classes: natural, artificial and semi-sealed. Comparison of reference data to original project statistics revealed the values of accuracy, commission and omission errors in the SSE dataset. Although, SSE accuracy in Poland fulfils the criteria set by SSE authors with overall accuracy of 99.5%, the individual analysis for each category reveals many weaknesses. Preliminary interpretation of mistakes leads to the conclusion that the spatial resolution of pictures used in the SSE project is insufficient. In several cases, validation proved that omission errors were made in relation to construction sites or recently constructed buildings. It should be stated that the accuracy of SSE product for Poland should be treated as the maximum value of impervious surfaces.

Opis:
There is an increasing interest in surfactants that comprise a linkage that breaks down in a controlled way. The most known examples of the cleavage mechanism include acid or alkaline hydrolysis, UV irradiation, enzymatic or heat decomposition. For practical reasons, the labile grouping can be inserted between the hydrophobic tail of the surfactant and the polar head group. Chemically and/or enzymatically induced cleavage of this labile bond would cause the separation of the polar part and the hydrophobic tail and, consequently, change of surface activity, an event usually referred to as the primary degradation of the surfactant. Dicephalic labile cationic surfactants belong to the class of surface active compounds with many potential applications often associated with their biological activity for a wide range of bacteria, viruses, fungi, or algae. Thus, they can be used in disinfecting agents or for protecting against the occurrence of these microorganisms. They adsorb well on negatively charged surfaces, which can be used in the treatment of fabrics. Due to excellent antistatic properties, they can be used for the final rinsing of fabrics, especially synthetic ones. In flotation processes, they can act as collectors, and in catalysis, they can be used as phase transfer catalysts or templates for zeolite synthesis. We present the surface quasi-two-dimensional electrolyte (STDE) model as a universal model for the description of ionic surfactants’ adsorption at fluid interfaces that explicitly considers the electric double formation upon surfactant adsorption. The model was adapted to describe phenomena occurring for adsorption of dicephalic surfactants as counterion specificity or formation of surfactant ioncounterion associates. As an example, we applied the model to explain the mechanism of adsorption at water/air interface of novel dicephalic cationic surfactants, N,N-bis[3,3′-(trimethylammonio)propyl]alkylamide dibromides and N,N-bis[3,3′-(trimethylammonio)propyl]alkylamide dimethylsulfates, both belonging to the class of chemodegradable surfactants having amide bond between two quaternary amine cationic groups and a single hydrophobic tail. Additionally, we used the same model to describe adsorption isotherms of N,N-bis[3,3- (dimethylamine)propyl]alkylamide dichlorides, having as two hydrophilic groups tertiary amines, which charge is pH-dependent. Application of the STDE model allowed an excellent description of experimental adsorption isotherm of dicephalic cationic surfactants and explained the specific features connected with the presence of multicharged headgroup.

Each year, global navigation satellite systems (GNSS) improve their accuracy, availability, continuity, integrity, and reliability. Due to these continual improvements, the systems are increasingly used in various modes of transport, including rail transport, the subject of this publication. GNSS are used for rail passenger information, rail traffic management, and rail traffic control. These applications differ in the positioning requirements that satellite navigation systems must meet. This article presents the methods and systems of rolling stock location and tracking using the Polish State Railways (PKP) as an example. The information on the equipment used for train positioning is not specified anywhere, hence they may differ, even for the same multiple units travelling in different parts of the country. In addition, the publication presents the progress of the European Train Control System (ETCS) implementation by the PKP.

Opis:
Background: Walks and marches are a simple yet effective forms of physical activity, commonly used in the cardiac rehabilitation. It has been recommended recently to combine march training with exercises involving upper limbs. One of the most popular methods is Nordic Walking, during which special poles are used to increase the work of upper part of the body. The aim of the study was to assess the influence of Nordic Walking on the improvement in exercise tolerance and physical performance in patients rehabilitated after a myocardial infarction.Methods: The study population consisted of 30 patients hospitalized in a cardiac rehabilitation ward 14 to 28 days after myocardial infarction. On admission and after completing the rehabilitation program patients performed an exercise test following the modified Bruce protocol, a six-minute walk test and a test assessing physical performance (Fullerton test). 10 subjects were assigned to a control group, which followed a standard training program, and 20 patients to a group which additionally performed a march training using the Nordic Walking method 5 times a week. Each session of the march training lasted 40 minutes and consisted of a 3-kilometer walk interrupted by breaks during which respiratory and stretching exercises were performed. During the march and exercises patients used special poles for Nordic Walking.Results: Exercise tolerance improved in both study groups. However, the increase in the exercise tolerance was greater in the group performing Nordic Walking than in the control group (30% vs. 14%, respectively; P < 0.05). The rate-pressure product during the exercise test increased significantly only in the group performing Nordic Walking (from 18.2 x 103 ± 3.3 x 103 to 20.7 x 103 ± 4.4 x 103; P < 0.05). The improvement in the results of the six-minute walk test was greater in the group performing Nordic Walking (22% in comparison with 17% in the control group; P < 0.05). The results of the test assessing physical performance (Fullerton test) improved in both study groups.Conclusion: The results of this preliminary study indicate that march training using the Nordic Walking method effectively increases exercise tolerance and physical fitness in patients after myocardial infarction. If these findings are confirmed by the results of larger studies, Nordic Walking could be widely used in the early phases of cardiac rehabilitation. The influence of Nordic Walking on the cardiovascular risk factors and quality of life parameters should be investigated.
Cel: Spacery i marsze są prostą a jednocześnie efektywną formą aktywności fizycznej powszechnie stosowaną w rehabilitacji kardiologicznej. W ostatnich latach podejmuje się próby urozmaicenia ćwiczeń marszowych poprzez szersze włączenie pracy kończyn górnych, co umożliwia między innymi coraz bardziej popularna forma aktywności ruchowej znana jako Nordic Walking. Celem niniejszej pracy była ocena wpływu marszu nordyckiego na stopień poprawy tolerancji wysiłku oraz sprawność ogólną chorych rehabilitowanych po zawale serca (ZS). Metoda: Badaniom poddano 30 pacjentów, którzy w okresie 14–28 dni po ZS przebywali na Oddziale Rehabilitacji Kardiologicznej. U wszystkich pacjentów włączonych do programu badawczego przed rehabilitacją i po jej zakończeniu wykonano próbę wysiłkową wg zmodyfikowanego protokołu Bruce’a, 6-minutowy test marszowy oraz test sprawności fizycznej „Fullerton”. Chorych podzielono na dwie grupy. 10 pacjentów uczestniczyło w standardowym programie treningowym (grupa K), a u 20 pacjentów zastosowano dodatkowo (5x w tygodniu po 40 min) trening marszowy typu Nordic Walking (grupa NW). Polegał on na przejściu 3 kilometrów z przerwami przeznaczonymi na ćwiczenia oddechowe i rozciągające. W trakcie marszu oraz ćwiczeń z pacjenci wykorzystywali specjalne kije skonstruowane do tej formy aktywności ruchowej Wyniki: W obu grupach trenujących uzyskano poprawę tolerancji wysiłku, jednak odsetek poprawy w grupie NW (30%) był wyższy niż w grupie K (14%). Podobnie zachowywały się wartości iloczynu podwójnego (RPP). Istotne statystycznie zwiększenie RPP po treningu rehabilitacyjnym stwierdzono jedynie w grupie z NW (z 18,2 x 103 ±3,3 x 103 do 20,7 x 103 ±4,4 x 103) (p<0,05). 6-minutowa próba marszowa wykazała wyższy odsetek poprawy w grupie NW (22%) niż w grupie K (17%). Wyniki testu „Fullerton” wykazują istotną statystycznie poprawę analizowanych parametrów w obu grupach. Wnioski: Wstępne badania wskazują na celowość wdrażania marszu nordyckiego do programów rehabilitacji kardiologicznej po zawale serca z uwagi na wysoką efektywność w zakresie wpływu na poprawę tolerancji wysiłku i sprawności fizycznej. Pełne zaadoptowanie Nordic Walking jako jednej z istotnych metod wczesnej rehabilitacji kardiologicznej będzie możliwe po dokonaniu i przeanalizowaniu większej liczby obserwacji poszerzonych o dodatkowe parametry, głównie w zakresie wpływu na czynniki ryzyka oraz parametry jakości życia.

Opis:
Introduction: Colorectal cancer is the second most common cancer worldwide. DNA double strand breaks (DSBs) are the most dangerous lesions which can lead to carcinogenesis. Nonhomologous end joining (NHEJ) is an important pathway, that allows for recovering DNA by direct end joining. The XRCC6 and LIG4 genes encode respectively Ku70 protein and human ATP-dependent DNA ligase, which are the components of the NHEJ repair pathway. The aim of our study was to evaluate the influence of XRCC6 C1310G and LIG4 T9I genes polymorphisms on colorectal cancer risk among Polish population. Materials and method: Genotyping was performed using TaqMan probes based on analysis of PCR products amplified in Real Time PCR. The research has been carried out on the material obtained from 100 patients with colorectal cancer and 100 cancer-free individuals who were age and sex-matched as a control group. The results were developed using the chi – squer test and odds ratio (OR). Results: Odd ratio analysis indicates reduced risk of colorectal cancer for LIG4 T9I polymorphism in heterozygotus model C/T (OR= 0.2717 95% CI= 0.1247-0,5918) and homozygous model T/T (OR= 0.3593 95% CI= 0.1394-0.9266). Similar situation we observed for XRCC6 C1310G gene polymorphism, which indicated on heterozygotus variant C/G (OR= 0.1181 95% CI= 0.0145-0.964) and homozygotus variant G/G (OR= 0.0972 95% CI= 0.0097-0.9713) to decrease the risk of colorectal cancer. Conslusions: Our research revealed XRCC6 C1310G and LIG4 T9I polymorphisms are associated with diminished risk of colorectal cancer. However, to confirm obtained results, a further investigations should be carried out.

Opis:
For many years, satellite systems have seen widespread use in a variety of technical applications, as well as in operations related to setting-out and the exploitation of track infrastructure. Their main applications include an inventory of the trackage course and detecting changes in its position. In both of these tasks, the most important element that determines the quality of an analyses is the high accuracy of the determinations being carried out. Satellite surveying techniques are not always sufficiently accurate, and in such cases, it is necessary to employ other land surveying methods to process surveying data. This article presents the authors’ considerations with regards to the possibility of applying one of the most common land surveying adjustment methods, the parametric method, to operations related to an inventory of tram infrastructure in Gdańsk. The results are based on surveys carried out during a surveying campaign in the autumn of 2018. The considerations presented in the article concern a small part of the research conducted under project No. POIR.04.01.01-00-0017/17 entitled “Development of an innovative method for determining the precise trajectory of a railborne vehicle” which is being implemented by a consortium of Gdansk University of Technology and Gdynia Maritime University

Opis:
The purpose of this research was to examine the impact of body composition on the anaerobic ability to generate strength and power produced separately by upper and lower limbs during dry-land and in-water (propulsion force) tests. Further examination included the influence of all gathered anaerobic strength indices on the results of 100-m front crawl race. Methods: The study involved 26 male swimmers (age: 19.8 ± 2.48 years). Fat-free mass, total body water and muscle mass of arms, legs, and trunk were measured. Dry-land average work, maximal power generated in 40-second arm-cranking test, and work generated in 20 countermovement jumps were evaluated. The forces generated separately by arms and legs were assessed during 40-second tethered swimming. All indices of body composition were found strongly correlated with indices of average work and maximal power generated by arms and legs in dryland tests. Results: Muscle mass of arms and trunk moderately and strongly (r = 0.44–0.64) influenced the force generated by arms in tethered swimming. There was no significance in the relationship of leg muscle mass and force generated by legs in tethered swimming. Significant relationships were observed between the results of the 100-m front crawl and the muscle mass of the arms, trunk, legs, as well as the average work and maximal power in the arm-cranking test (r: 0.39–0.54). The average impulse of arm force and maximal leg force in tethered swimming moderately and significantly correlated with 100-m swimming results. Conclusions: The study concludes the relevance of developing muscle mass balanced to the body size, which is involved in propulsion force production in sprint front crawl swimming.

Opis:
This article examines one of the basic issues related to the technique of mobile satellite measurements in railway tracks. This problem concerns the correction of the determined coordinates of the track centerline. The need to perform this operation results from the GNSS receivers positioning at a certain height above the level of the existing track axis, leading to longitudinal and lateral shifts of antennas. The key problem here is the determination of the local horizontal coordinate system in each measured position. For the analysis, the authors defined the directional baseline vector of the measuring platform on the basis of positions given by two satellite antennas, positioned over the pivots of its bogies. This work presents the procedure for determining the corrections values.
W pracy poruszono jedną z podstawowych kwestii związanych z techniką mobilnych pomiarów satelitarnych w torze kolejowym – korygowanie wyznaczonych współrzędnych osi toru. Konieczność przeprowadzenia tej operacji wynika z ustawienia anten GNSS na pewnej wysokości nad poziomem istniejącej osi toru, przy występowaniu jego pochylenia w kierunku podłużnym i poprzecznym. Kluczowym problemem staje się przy tym konieczność określania w każdym punkcie pomiarowym kierunków osi układu współrzędnych w płaszczyźnie poziomej. W omawianej metodzie posłużono się kierunkowym wektorem bazowym, wyznaczonym na podstawie współrzędnych anten usytuowanych nad czopami skrętów obydwu wózków platformy. W pracy przedstawiono procedurę określania wartości korekt.

Opis:
Because of its harmfulness to human health, asbestos has been banned in 55 countries, including the EU. In Poland, the use and production of asbestos and asbestos-containing products has been forbidden since 1997. However, there is no precise data about the amount of asbestoscontaining products to be eliminated from the territory of Poland. This survey aims to identify characteristics that have a significant impact on the estimation of asbestos-containing products used in Poland. Statistical correlation between the results of the physical inventory count done in 155 municipalities was examined. As a result of the survey it was found that the amount of asbestos-cement roofing depends on the following factors: the number of individual farms in the village, the distance from the asbestos manufacturing plants, the age of the buildings and the economic situation of municipality. The results obtained may contribute to the ability to predict the amount of asbestos-containing products used in other municipalities.

Opis:
The article discusses the applicability of a novel method to determine horizontal curvature of the railway track axis based on results of mobile satellite measurements. The method is based on inclination angle changes of a moving chord in the Cartesian coordinate system. In the presented case, the variant referred to as the method of two virtual chords is applied. It consists in maneuvering with only one GNSS (Global Navigation Satellite System) receiver. The assumptions of the novel method are formulated, and an assessment of its application in the performed campaign of mobile satellite measurements is presented. The shape of the measured railway axis is shown in the national spatial reference system PL-2000, and the speed of the measuring trolley during measurement is calculated based on the recorded coordinates. It has been observed that over the test section, the curvature ordinates differ from the expected waveform, which can be caused by disturbances of the measuring trolley trajectory. However, this problem can easily be overcome by filtering the measured track axis ordinates to obtain the correct shape – this refers to all track segments: straight sections, circular arcs and transition curves. The virtual chord method can also constitute the basis for assessing the quality of the recorded satellite signal. The performed analysis has shown high accuracy of the measuring process.

Opis:
The Lower Devonian of the Holy Cross Mountains is well-known in the field of vertebrate palaeontology but remains unrecognized as regards palaeoenvironmental reconstructions. We therefore analysed the spatial distribution and relative abundance of fossil vertebrates in this area within one time interval. The fauna from an Early Devonian (Emsian) siliciclastic bone-bearing breccia (the “Placoderm Sandstone”) exposed in four sections of the Łysogóry region and five sections of the Kielce region was analysed with respect to the frequency of the remains and their taxonomic affinity. The relative abundances of agnathans, acanthodians, placoderms, osteichthyans and chondrichthyans suggest more open marine conditions in the Łysogóry region and more terrestrial-influenced in the Kielce region during the Emsian. The results show that the average agnathan and acanthodian content of the Łysogóry region is significantly larger than that in the Kielce region. On the other hand, there are relatively fewer osteichthyans in the Łysogóry region and a significantly higher proportion of bony fishes was recorded in the fauna of the Kielce region. Placoderms are characterized by their generally similar frequency in both regions and from site to site in each of them, though a greater abundance was noted from the Kielce region. Likewise differences in the proportions of particular groups in the Kielce region suggest a large variety of marginal-marine environments under the influence of factors that might have included marine currents and variable conditions around a river mouth.
