Application of optical reflectometer for monitoring corrosion process
Authors: Kochanowicz Marcin , Markiewicz Jakub
Published: July 2022

In this work, a corrosion sensor based on an optical time domain reflectometer was presented. The first sensor with a bare tip was used to measure the corrosion process of silica glass fiber. Another sensor with a deposited silver layer was used for monitoring the corrosion process in nitric acid. In both cases, reflectance at the end of the fiber was decreasing with immersion time. Thus we can describe the corrosion stage by the level of fresnel reflectance. The maximum sensitivities of the analyzed sensors were as follows: 0.7dB/min (3% HF solution) 0.15dB/h (5%HNO3 solution) Results showed that the corrosion process in all cases wasn’t fully linear, and all reactions began almost instantly after immersing sensors in tested corrosive environments.

Optoelectronic system for detecting short-circuits in low voltage networks
Authors: Barczak Kamil , Juraszek Janusz
Published: July 2022

The paper presents the concept of using a fiber-optic current sensor with external conversion (OFCS-EC) in a power system. The sensor was developed in the Department of Optoelectronics and was tested in a laboratory. The focus was on the use of OFCS-EC in a real low voltage network. The main purpose of the presented measurement system will be to record network disturbance states with high accuracy. The experiment is to answer the question whether the recorded current waveforms in fault states and the measurement transmission speed will be useful enough to be able to predict, identify and, consequently, prevent losses and damage to devices caused by disturbances in low voltage networks.

Published: July 2022

ABSTRACT. Carissa spinarum Linn. is an incense plant traditionally used in Ethiopia and other countries for the treatment of numerous diseases. It also exhibits different biological activities, and different classes of natural compounds were previously reported from the plant. In this study, the essential oil from the roots of C. spinarum together with medicinal smoke obtained from burnt roots of C. spinarum were analyzed by GC-MS. The essential oil of C. spinarum roots was predominantly composed of 2-hydroxyacetophenone (82.97%). The dominant components in the n-hexane soluble fraction of the smoke derived from the roots of C. spinarum were 2,6-dimethoxyphenol (14.16%), 2-methoxyphenol (10.34%) and 2-hydroxyacetophenone (9.51%). On the other hand, the major components in the MeOH-soluble fraction were 2,6-dimethoxyphenol (17.51%), 2-methoxyphenol (13.02%) and 2-hydroxyacetophenone (10.98%). The smoke derived from the roots of C.  spinarum showed 92.60 ± 0.34% DPPH inhibition at concentration of 100 µg/mL. At the same concentration, standard ascorbic acid scavenged the DPPH radical by 96.09 ± 0.16%. This result supports the traditional medicinal use of the plant material as a skin-care and wound healing agent most likely due to the presence of simple phenols and other biologically active compounds.

ABSTRACT. Murraya koenigii is known for its health benefits against constipation, diarrhea, bacterial infections, wounds and skin related diseases. Aim of this project is to determine cytotoxic aptitude of antioxidant compounds present in M. koenigii. The fractionation of M. koenigii shoots methanol extract was carried out with different solvents followed by determination of total phenolic content, radical scavenging potential along with phenolic profile. M. koenigii shoot fractions were analyzed for their cytotoxic potential by MTT assay besides evaluating molecular interactions between identified phenolics with Bcl-2, Bcl-xl and MCL-1. The results revealed that butanol fraction contains maximum amount of quercetin, 4-hydroxy-3-methoxy benzoic acid and trans-4-hydroxy-3-methoxy cinnamic acid. Ferulic acid is abundant in water fraction whereas n-hexane fractions contain sinapic and vanillic acids. The ethyl acetate fraction possess the highest level of phenolics as well as radical scavenging potential. HPLC results show that 9 organic acids are present in ethyl acetate and butanol fractions. The highest cytotoxic activity was exhibited by n-hexane and ethyl acetate fractions. Molecular docking studies supports that ethyl acetate and n-hexane fractions are the major sources of antioxidant and cytotoxic compounds. Also, molecular interactions exist between identified phenolics from plant shoots fractions with anti-apoptotic proteins Bcl-2, Bcl-xl and MCL-1.

Published: July 2022

ABSTRACT. Biflavonoids are C-C or C-O-C linked flavonoid dimers with highly restricted presence in plant species. They are extensively reported to possess interesting pharmacological properties. The chromatographic fractionation and purification of CH2Cl2/MeOH (1:1) extract of the root of Rhus ruspolli led to the isolation of a new biflavonoid (1) along with four other known biflavonoids (2-5). The structure of the compounds were identified based on the analysis of NMR spectroscopic and mass spectrometric data and also in comparison with reported literature data.  Compounds 2-5 were assayed for their antioxidant activity using DPPH and displayed potent in vitro antioxidant activities. The percentage radical scavenging activities were 78.32, 68.90, 93.22 and 92.00 for compounds 2-5, respectively. The highest activity was observed for compound 4 and 5 with IC50 values of 7.90 and 8.40, respectively, which are even greater than that of ascorbic acid (IC50 9.90).  The high antioxidant activity of the compounds could be due to the presence of free hydroxyl groups in the flavonoids. The antioxidant activities of these compounds support the traditional uses of the plant in treatment of wound, ectoparasite and as antibacteria and indicates the potential use of these compounds as drug lead candidates.

Trace level enrichment and clean-up of β-lactam antibiotic residues in edible chicken tissues and feathers by solid phase extraction for quantitative determination utilizing liquid chromatography
Authors: Lakew Aynalem , Megersa Negussie , Singh Chandravanshi Bhagwan
Published: July 2022

ABSTRACT. A simple analytical method for the extraction and determination of three β-lactam antibiotics in chicken tissues and feather samples was developed and validated using solid phase extraction (SPE) and liquid chromatography-ultraviolet, LC-UV, detection. The analytes were extracted with strong anion exchange (SAX) cartridges for the extract clean-up and enrichment before introduction into the LC system. The validation was carried out based on the recommendations from Commission Decision 2002/657/EC. Under optimised conditions, the proposed method offers correlation coefficients of r2 ≥ 0.9991 for all the studied analytes in both matrices. Percent recovery results were found to vary between 79.7-101.8% and 94.2-101.6% for chicken feathers and tissues, respectively, with the relative standard deviation, RSD < 8.4%. The limits of detection (LOD) were in the range of 0.1-0.13 µg kg-1 and 0.1-0.15 µg kg-1 while the limits of quantification (LOQ) were in the range of 0.3-0.38 µg     kg-1 and 0.3-4.5 µg kg-1 in chicken feathers and tissues, respectively. The proposed method offers good sensitivity and selectivity and all the results demonstrating that the method would be widely used for determination of β-lactam antibiotics and other trace level antibiotics residues having similar physical and chemical properties in the matrices of varying origins.

ABSTRACT. Magnetic nanoparticles (MNPs) are gaining popularity because of their small size allowing for research into the fundamentals of magnetism. In wastewater treatment, adsorption methods commonly remove heavy metals, but copper (Cu+2) ion removal using magnetic nanoparticles (NPs) has not been investigated. In this study two different modes were used to determine maximum adsorption capacity to remove copper(II). The nanoparticles containing the Fe3O4 with Chlorella, core-shell Fe3O4/SiO2 with Chlorella sp. synthesized and characterized by Fourier transform infrared (FT-IR) analysis, the morphology observed by scanning electron microscope (SEM), crystalline structure, and grain size provided by energy dispersive X-ray (EDX) and X-ray diffraction (XRD). Copper(II) ion removal showed in both modes. The maximum copper(II) ion reduction percent was obtained by nanoparticles containing core-shell Fe3O4/Chlorella 80.3%, Fe3O4/SiO2 with Chlorella sp. (86.9%) the result showed maximum removal using Fe3O4/SiO2 with Chlorella sp. due to increase of surface area. The results indicate that the adsorption using magnetic nanoparticles with Chlorella sp. enhances the cell surface and provides easy access to the separation for both preparation and recapture.

Monitoring magma migration at Mt. Etna using the Seismic Amplitude Ratio Analysis method
Authors: Rasaneh Ghazaleh , Hajian Alireza , Hodhodi Maryam , Kimiae Roohollah , Gambino Salvatore
Published: July 2022

The Seismic Amplitude Ratio Analysis method (SARA) was applied to data recorded six days before the May 13, 2008 eruption of Mt. Etna to test its potential as a forecasting attribute. By using this method, the magma migration path, as well as the seismic migration, can be determined with the amplitude of continuous data recorded at least at one pair of stations from a seismic network near the eruption site. Due to the sudden changes in the seismic amplitude ratio calculated for each pair of stations, the seismic migration trend, as well as the magma path at depths, were detected before the main eruption. The start and end times of the seismic swarms were also determined. The standard practice to achieve similar results is to use volcanic tremors, which must be pre-selected thus reducing efficiency and increasing the time needed. By using the whole seismic signal, the method provides a simpler semi-automated alternative, especially for a seismic event or places where it is not possible to record tremors continuously. This simple method is useful to reduce uncertainties relative to hazardous magma propagation during volcanic unrest, as it helps improve the accuracy of locating seismic swarms and determining the direction of magma movement at depth before the eruption. We also analyzed the amplitude ratio trend using Mann-Kendall and Sen's estimator test. The results of these tests confirmed a positive and increasing trend from the day before the eruption in most pairs of stations.
Wielka wojna w „Dzienniku” Aleksandry Czechówny (część I: 2 lipca 1914 r. – 26 grudnia 1914 r.)

The Great War in the “Journal” of Aleksandra Czechówna (Part I: 2 July 1914 – 26 December 1914)

Aleksandra Czechówna (1839–1923) was the daughter of Tomasz Czech and Aleksandra, née Zielińska. Her Dziennik z całego życia (Journal from the whole life) ... written almost constantly for over 60 years (1856–1923), is stored in the National Archives in Krakow, ref. no. 29/428/1–29/428/44 (former ref. no. IT 428/1–428/44). It represents a wonderful source presenting the cultural, social and daily life of the town of Krakow in the second half of the 19th century, as well as in the first two decades of the 20th century. The text placed here comes from two volumes of the “Journal”. There is a short fragment from volume 38, ref. no. 29/1582/38 (former ref. no. IT 428/38) as well as the main text from volume 39, ref. no. 29/1582/39 (former ref. no. IT 428/39). It contains entries concerning the outbreak of the First World War and the first year of the fighting. The presented selection of “Journal” was written by a woman carefully observing events which were of great importance for Poles. The author probably mainly used press reports, but also tried to use personal accounts. She is quite well informed and up-to-date with the developing events. The “Journal”, although it is not complete, supplies a wide range of information about events taking place on the eastern front, especially in Krakow and its immediate vicinity. The diary also brings the reality of the daily life, full of care and uncertainty, closer to the reader. It provides a picture of the moods and views prevalent among the residents of Krakow.
Ariadne's Weaving in the Musical-Visual Field
Authors: Aleksić Milica
Published: July 2022

Recognition and reflection of the radially structured semantic intertextual raster in the opera Ariadne auf Naxos Op. 60 by Richard Strauss and Hugo von Hofmannsthal, are the goals of this paper, with the awareness that ‘reading’ of this complex textual amalgam cannot be comprehensive and that this is only one of the possible ways of looking at different languages, their texts, and relationships in which they come in, with the emphasis on the connection between the music and architectural texts. The focus is to spot some of the paths in this specific music-scenic maze. The recognition of the ‘inner’ and ‘outer’ opera house implies the withdrawal of the parallels between the music-dramatic and the architectural level. The concept of ‘opera within the opera’ is simultaneously present in the musical-dramatic sphere (opera Ariadne in opera Ariadne auf Naxos) and in the architectural sphere (opera/residential house in the opera house). By concurring with the different meaning of the word ‘opera’ which it has in the music-drama (opera as a musical-drama work) and architectural language (opera as an architectural object), we carry out the terms meta-opera ‘per square’ (‘metaopera’) and meta-opera ‘per cube’ (‘metaopera’).
Biskup Aleksander Bereśniewicz wobec klasztorów w Wielkopolsce Wschodniej (1883-1902)
Authors: Prejs Roland
Published: July 2022

Biskup Aleksander Bereśniewicz objął rządy diecezją kujawsko-kaliską, której częścią była Wielkopolska Wschodnia, w trudnym okresie. Był to czas po powstaniu styczniowym, a jednym z problemów była kasata klasztorów w Królestwie Polskim, jako konsekwencja tego zrywu rewolucyjnego. Wiele klasztorów uległo całkowitej likwidacji, część z nich stała się etatowymi, w których gromadzono zakonników, czekając na ich wymarcie. Biskup Bereśniewicz starał się, w miarę swoich możliwości, ratować i podtrzymywać ich egzystencję. Choć nie było to łatwe, a trudności piętrzyły się ze strony władz zaborczych.

It was a time after the January formation, and a dissolution of monasteries was one of the greater problems in the Congress Kingdom of Poland established in 1815 at the Congress of Vienna, as a consequence of this revolutionary dash. Many monasteries surrendered to the total liquidation, the part of them was “full-time” monasteries , where monks were being drawn waiting for their dying out in. Bishop Bereśniewicz tried to redeem as his alternatives made him able to do, just enough to save and to support their existence. At least it wasn’t simple, and problems piled up on the part of possessive authorities.

Published: July 2022

Dzieje Ochotniczej Straży Pożarnej w Tuliszkowie sięgają 1878 r. Wówczas doszło do zorganizowania jednostki, która nie uzyskała zgody na rejestrację. Jesienią 1905 r. zawiązał się komitet, który doprowadził do założenia jednostki w mieście. Straż została zarejestrowana z dniem 19 lipca 1906 r. Pod koniec 1906 roku wybudowano pierwszą, drewnianą remizę, a w kolejnym roku założono orkiestrę. W 1910 r. oddano do użytku nową murowaną remizę. W okresie międzywojennym oprócz działalności statutowej, druhowie wykazywali dużą aktywność na rzecz miasta. Organizowano liczne imprezy o charakterze dochodowym, a w 1923 r. założono Koło Miłośników Sceny. Władze straży kładły nacisk na wyszkolenie i wyposażenie jednostki, strażacy brali także aktywny udział w działalności innych stowarzyszeń. Wielu druhów udzielało się także w miejskim samorządzie. Podczas II wojny światowej Niemcy wyposażyli jednostkę w samochód bojowy oraz dwie motopompy. Kilkoro strażaków zamordowano w obozach koncentracyjnych. Pierwszym powojennym prezesem jednostki został Józef Patrzykąt, jej współzałożyciel i były naczelnik. The history of the Volunteer Fire Department in Tuliszków in 1906-1945 The history of the Volunteer Fire Department in Tuliszków dates back to 1878. At that time there was founded unit that did not receive the consent for registration. In the autumn of 1905, a committee formed, which led to the establishment of a unit in the city. The Voluntary Fire Department was registered on 19 July 1906. At the end of 1906, the first wooden fire-station was built, and in the following year the orchestra was established. In 1910 a new brick fire-station was commissioned. In the interwar period, besides statutory activity, firefighters showed great activity for the city. Numerous lucrative events were organized and the Koło Miłośników Sceny was founded in 1923. The authorities insisted on the training and equipment of the unit, firefighters also took an active part in the activities of other social organizations. Many of the firefighters were also involved in the municipal government of the city. The Germans provided the unit with a fire truck and two fire pumps during the Second World War. Several firefighters were murdered in concentration camps. Józef Patrzykąt, the co-founder of the Volunteer Fire Department and former fire brigade chief, was the first post-war chairman of the Volunteer Fire Department in Tuliszków.

Sztandar Cechu Malarzy i Lakierników z Kalisza. Projekt z 1936 roku w dokumentacji Urzędu Wojewódzkiego Łódzkiego
Authors: Adamczewski Marek
Published: July 2022

Uwarunkowania prawne z 1935 r. zdecydowały o tym, że mistrzowie Cechu Malarzy i Lakierników z Kalisza w 1936 r. przedstawili projekt sztandaru cechowego z prośbą o jego zatwierdzenie przez właściwą władzę administracyjną. Jest on ciekawy przede wszystkim z uwagi na formę dwóch wyobrażeń użytych do zbudowania przekazu ikonograficznego prawej i lewej strony odznaki, tj. polskiego orła państwowego i herbu Kalisza. Projektujący sztandar wykorzystał polskie godło państwowe do zbudowania prawej stronie sztandaru, ale głęboko przetworzył historyczną formę Orła Białego, a inspiracją w tym zakresie był zapewne kubizm. Równie przetworzony został herb Kalisza ze sztandaru malarzy i lakierników. Projektujący prostymi i załamującymi się ostro liliami wykreślił mur miejski, wieże i strażnika, szczególnie jego ubranie. Stworzył herbu Kalisza obcy tradycyjnej formie heraldycznej, ale spójny z „kubistycznym” orłem z prawej strony sztandaru.

Banner of the Guild of Painters and Varnisher from Kalisz. Projectfrom 1936 in documentation of the Łódź Province Office

Legal conditioning from 1935 decided, that masters of the Guild of Painters and varnishers from Kalisz in 1936 had described the project of the guild banner with the request for approving its by the competent authority administrative. It is interesting project mainly due to the form of two ideas used for building the iconographic transmission right of both the left hand of the badge, i.e. the Polish national eagle and the coat of arms of Kalisz. The designer of the flag used the Polish national emblem for building for the right side of the banner, but he processed the historical form of the Eagle of the White, and in this respect probably a cubism was an inspiration. Planes a coat of arms of Kalisz was processed from the banner of painters and varnishers. The designer with straight and collapsing sharply lilies deleted the municipal wall, towers and the guard, specially his dress. He created the coat of arms of Kalisz different to the heraldic traditional form, but cohesive from „cubist” with eagle on the right of banner.

Authors: Zhuk Inna
Published: July 2022

The effectiveness of the functioning of the state’s monetary system and the implementation of targeted economic policies with the help of the financial management mechanism depends on the organization of the management of the state’s funds. The study aims to find effective digitalization tools to improve public administration in the financial sector. To achieve the goal, the authors analyzed which countries are the most advanced in the use of digitalization tools in the public administration system, identified the most effective tools in terms of the feasibility of their implementation, and developed recommendations for improving the digitalization of the public administration system in the field of finance. Digitalization of public administration processes can potentially lead to a reduction in the number of officials, an increase in the efficiency of administration (by increasing the objectivity of decisions made and eliminating the possibility of technical errors when making legal decisions), an increase in the quality and accessibility of public services by transferring them to a digital format, as well as increasing their security level. The use of blockchain technology in the system of public financial management will help to cope with corruption, strengthen the state apparatus, increase citizens’ confidence in the authorities and thereby indirectly increase investment activity in the country.

Günümüzde lastik tekerlekli kent içi toplu taşıma araçlarının yerini tren, metro, tramvay, hafif raylı sistemler gibi daha modern, düzenli ve konforlu toplu taşıma sistemleri almaktadır. Bunlardan en yaygın uygulanan sistem raylı sistemlerdir. Raylı sistem elemanları açık havada çeşitli çevresel etkiler altındadır ve elemanlar tasarlanırken bunlar göz önüne alınmalıdır. Bu çalışmada karayollarıyla hemzemin veya temas halindeki raylı sistemlerin traverslerinin çevre şartlarına bağlı olarak çatlama ve bozulmalarını önlemek ve servis ömrünü uzatmak amaçlanmıştır.

Bu deneysel çalışmada metot olarak, karayollarında buzlanmayla mücadelede kullanılan kimyasal yöntemlerin, raylı sistem elemanlarından traverslere vereceği zararı önlemek için farklı dozajlarda bazalt tozu kullanılarak numuneler üretilmiş ve deneyler gerçekleştirilmiştir. Hacimce %0, %5, %10, %15 ve %20 oranlarında çimento ile ikame edilerek bazalt tozu (havuz çökeltisi, d=90µ) katkılı beton ve LVT (low vibration track) tipi ikiz-blok traversler için 5 farklı seri numuneler üretilerek beton deneyleri ile traversler üzerinde durabilite deneyleri gerçekleştirilmiştir. Buz çözücü tuz etkisi için katkısız ve bazalt katkılı numunelerin yüzeyine 0,150 gr/cm2 miktarında NaCl ham tuz konsantrasyonu uygulanarak donma çözülme deneyi gerçekleştirilmiştir.

Numuneler akışkanlaştırıcı katkı maddesi kullanarak üretilmiştir. Taze beton için kıvam tayini, su emme, hava içeriği deneyleri, sertleşmiş beton için basınç, yarmada çekme, eğilme, aşınma ve donma çözülme deneyleri yapılmıştır.

Travers numuneler uygulamada kullanıldığı gibi üzerine raylar monte edilerek basınç dayanımı için yükleme yapılmış, böylelikle bazalt tozu katkısının traverslerin özelliklerine etkileri gerçeğe yakın davranışlarla belirlenmiştir. Sonuç olarak dayanım ve durabilite özellikleri açısından kıyaslamalar yapılarak elde edilen sonuçlar, bazalt tozunun beton traverslerin durabilite özelliklerinde oluşturacağı iyileştirme düzeyinin belirlenmesine olanak sağlamıştır.

Objective: The objective of this study was to investigate physiological responses and movement profiles of amputee soccer players during official matches.

Material and Methods: Five outfield amputee soccer players with a 9.20±0.81 years of amputee soccer experience (age 28.60±5.32 years; height 1.71±0.05 m; body mass 71.54±9.39 kg) volunteered for this study. Physiological responses [blood lactate (BLa), heart rate (HR) and ratings of perceived exertion (RPE)] and activity profiles [peak speed, total distance covered (TD), TD at five speed categories (SC), percentages of TD at five SC and time spent in four maximal heart rate (HRmax) zones] were analyzed during seven official amputee soccer matches.

Results: Mean game BLa, RPE, HR and HRmax were 5.58±1.63 mmol.L-1, 9.43±2.62, and 151.77±16.05 bpm and 180.74±9.23 bmp, respectively. HRmax was higher in the first half than in the second half (p=0.02). Players covered 102.62±7.24 m.min-1 and this did not change between the halves during amputee soccer matches (p=0.40). TD at very low SC was 73.86±0.57 m.min-1 whereas TD at very high SC accounted only for 0.24±0.04 m.min-1. Similarly, the percentage of the TD at very low SC was 70.18±10.30% and the percentage of the TD at very high SC was 0.24±0.04%. Amputee soccer players spent ~31 min and ~15 min at high intensity and moderate HRmax zones, respectively. These accounted only about ~5 min at very low and low intensity HRmax zones during whole matches.

Conclusion: These results showed that amputee soccer played at the professional level is a high-intensity exercise, which could be used to prescribe amputee soccer specific training regimes.
