2023 JOURNAL OF MOLECULAR LIQUIDS
The extraction of furfural (FF) and 5-hydroxymethylfurfural (HMF) from hydrolysates is currently one of the main challenges in bio-refinery. In this work, the separation of FF and HMF from the aqueous phase was carried out using a new type of green solvents – Magnetic Deep Eutectic Solvents (MDES). A conductor-like screening model for realistic solvents (COSMO-RS) was used for the preselection of 400 MDES. MDES which exhibit the highest FF and HMF solubility were prepared. The detailed physicochemical (i.e. density, viscosity, melting point) and structural characterization of new solvents using spectroscopic analysis and density functional theory (DFT) were performed. The most important liquid–liquid extraction parameters, i.e. the type of MDES, pH, temperature, extraction time, and the ratio of MDES to aqueous phase were carefully optimized using Central Composite Design model (CCD). In addition, multistage extraction, MDES regeneration, and reusability were also examined. The obtained results indicate that MDES consisting of menthol, thymol, and FeCl3 in a 1:1:0.5 M ratio could easily extract both FF and HMF from model and real hydrolysates samples with 98.5 and 78.8 % efficiency, respectively. The MDES regeneration studies demonstrated that the extraction efficiency did not change after 15 regeneration cycles. The mechanism of FF and HMF extraction indicates that van der Waals interactions were the main driving force for the extraction process. A great advantage of the proposed method was the possibility to eliminate the tedious centrifugation step for phase separation by using solvents with magnetic properties.
Magnetic signature reproduction of ferromagnetic ships at arbitrary geographical position, direction and depth using a multi-dipole model

The reproduction of magnetic signatures is an important issue concerning the safety of ship traffic, as well as the identification and classification of vessels. Moreover, military applications of magnetic signatures and their reproduction refer to the activation or protection against activation of magnetic naval mines. Previous works on this subject focused on recording and replicating the signatures under the same conditions as those under which they were measured, e.g., on the same ship courses. In this article, much greater capabilities of the multi-dipole model are presented, including simultaneous identification of permanent and induced magnetism. Determining the dipole values using the data from cardinal directions gives the possibility of determining the magnetic field density at any trajectory (position), direction, or depth, with further reconstruction of the entire magnetic field on the basis of residual measurements. For the purpose of this article, a numerical test model of a corvette-type ship has been modelled in Opera simulation software for different geographical positions. The synthetic data from the simulator served as the data source for determining the parameters of the multi-dipole model and the reference data for the verification of the signatures reconstructed for other positions, directions, and depths than those used to determine the model parameters. To determine all permanent magnetization components, data sets were used for two different values of the external magnetic field vertical component. Finally, as a culmination of the demonstration of model universality, the entire magnetic field around the ship was reproduced for different control points on Earth, and for different courses and depths. Investigating the possibility of reconstructing the magnetic signature at a different geographic location than the place where the measurement was made for model synthesis is the main original issue considered in this paper.

In this study, a novel TiO2/Ti3C2/MnFe2O4 magnetic photocatalyst with dual properties, enabling (i) improved photocatalytic degradation with PMS activation under simulated solar light and (ii) magnetic separation after the degradation process in an external magnetic field was developed and applied for the efficient photodegradation pharmaceutically active compounds (PhACs) frequently present in wastewater and surface waters worldwide. MXene was used as a Ti precursor for anatase/rutile synthesis and as a co-catalyst in the photodegradation process. Manganese ferrite with ferrimagnetic properties was coupled with the TiO2/Ti3C2 composite to facilitate the magnetic separation after the purification process in an external magnetic field. Moreover, MnFe2O4 was used for PMS activation, producing •SO4- radicals with a strong oxidation ability and higher redox potential of 2.5–3.1 V (vs. NHE) than •OH radicals with a standard oxidation–reduction potential of 2.8 V. The effect of the manganese ferrite content in the composite structure (5 wt% and 20 wt%) on the physicochemical properties and photocatalytic activity of the magnetic photocatalyst was investigated. Furthermore, the most photocatalytic active composite of TiO2/MXene/5%MnFe2O4 was used for peroxymonosulphate-assisted photocatalytic degradation of ibuprofen and carbamazepine. The effect of peroxymonosulphate concentration (0.0625 mM, 0.125 mM, and 0.25 mM) and the synergistic effect of PMS activation on photocatalytic degradation was studied. Based on the obtained results, it was found that TiO2/MXene/5%MnFe2O4/PMS process is an efficient advanced treatment technology for the oxidation of emerging contaminants that are not susceptible to biodegradation. Carbamazepine and ibuprofen were completely degraded within 20 min and 10 min of the PMS-assisted photodegradation process under simulated solar light. The trapping experiments confirmed that •SO4- and •O2- are the main oxidising species involved in the CBZ degradation, while •SO4- and h+ in the IBP degradation. Furthermore, introducing interfering ions of Na+, Ca2+, Mg2+, Cl-, and SO42– in the model seawater did not affect the removal efficiency of both pharmaceuticals. In terms of reusability, the performance of the TiO2/MXene/5% MnFe2O4/PMS photocatalyst was stable after four subsequent cycles of carbamazepine and ibuprofen degradation.

he BaTiO3 perovskite is widely used in the electronic technology due to its dielectric, piezoelectric and ferroelectric properties and is a well-known base for obtaining a promising multifunctional material. In this paper we report the extensive studies on the Co-doped BaTiO3 ceramics for the wide range cobalt content. Full structural characterization of studied samples in a 20–450 K range was provided. The results of research on spectroscopic, dielectric, electronic, optical, magnetic and elastic properties are presented. The superior dielectric properties to those exhibited by the parent compound have been found. Namely, the reduction of dielectric losses and stability of the dielectric permittivity in the vicinity of the room temperature are reported. Additionally, our research revealed: broadening of the dielectric anomalies related to the ferroelectric-paraelectric phase transition, shifting the Curie point towards lower temperatures, displacive mechanism of Curie phase transition with order-disorder contributions; maximum value of the real part of dielectric permittivity of about 5000 at Curie point for 0.05 wt% of Co-doping, value of the activation energy ∼ 0.9 eV as the result of the migration of oxygen vacancies that are generated due to charge compensation, and the occurrence of magnetoelectric response. At last, the Co-doped BaTiO3 shows potential to use in non-linear optoelectronic devices, while no evidence of multiferroic properties, suggested in the literature, was found.

2023 TRENDS IN FOOD SCIENCE & TECHNOLOGY
Background The biodegradable, biocompatible, sustainable, and renewable nature of biomaterials has led to increased interest in developing biopolymeric food packaging films (BFPFs) with green ingredients and strategies. To enhance the performance of these films, biopolymer molecules can be modified or combined with additives like nanomaterials, cross-linkers, bioactive compounds, and other polymers, particularly with Maillard-reaction (MR), as a promising approach to enhance the performance of degradable BFPFs. Scope and approach In this work, after an overview of MR chemistry, the MR in different types of biopolymers have been discussed in detail. In addition, this work summarizes the application of MR cross-linked BFPFs in recent years. Key findings and conclusions The MR is an effective cross-linking method that can improve the properties of BFPFs. The extent of cross-linking induced by MR depends on the reaction degree, and its occurrence can be controlled during different stages of film-formation solution and drying. The initiation of MR requires a specific temperature range. Additionally, MR products can serve as functional additives that provide antibacterial and antioxidant activities to BFPFs.

Recently, because of serious global challenges including the consumption of energy and climate change, there has been an increase in interest in the environmental effect of port operations and expansion. More interestingly, a strategic tendency in seaport advancement has been to manage the seaport system using a model which balances environmental volatility and economic development demands. An energy efficient management system is regarded as being vital for meeting the strict rules aimed at reducing the environmental pollution caused by port facility activities. Moreover, the enhanced supervision of port system operating methods and technical resolutions for energy utilisation also raise significant issues. In addition, low-carbon ports, as well as green port models, are becoming increasingly popular in seafaring nations. This study comprises a comprehensive assessment of operational methods, cutting-edge technologies for sustainable generation, storage, and transformation of energy, as well as systems of smart grid management, to develop a green seaport system, obtaining optimum operational efficiency and environmental protection. It is thought that using a holistic method and adaptive management, based on a framework of sustainable and green energy, could stimulate creative thinking, consensus building, and cooperation, as well as streamline the regulatory demands associated with port energy management. Although several aspects of sustainability and green energy could increase initial expenditure, they might result in significant life cycle savings due to decreased consumption of energy and output of emissions, as well as reduced operational and maintenance expenses

Mangiferin is a strong antioxidant that presents a wide range of biological activities. The aim of this study was to evaluate, for the first time, the influence of mangiferin on tyrosinase, an enzyme responsible for melanin synthesis and the unwanted browning process of food. The research included both the kinetics and molecular interactions between tyrosinase and mangiferin. The research proved that mangiferin inhibits tyrosinase activity in a dose-dependent manner with IC50 290 +/− 6.04 µM, which was found comparable with the standard kojic acid (IC50 217.45 +/− 2.54 µM). The mechanism of inhibition was described as mixed inhibition. The interaction between tyrosinase enzyme and mangiferin was confirmed with capillary electrophoresis (CE). The analysis indicated the formation of two main, and four less significant complexes. These results have also been supported by the molecular docking studies. It was indicated that mangiferin binds to tyrosinase, similarly to L-DOPA molecule, both in the active center and peripheral site. As it was presented in molecular docking studies, mangiferin and L-DOPA molecules can interact in a similar way with surrounding amino acid residues of tyrosinase. Additionally, hydroxyl groups of mangiferin may interact with amino acids on the tyrosinase external surface causing non-specific interaction.

One of the most common types of natural disaster, floods can happen anywhere on Earth, except in the polar regions. The severity of the damage caused by flooding can be reduced by putting proper management and protocols into place. Using remote sensing and a geospatial methodology, this study attempts to identify flood-vulnerable areas of the central district of Duhok, Iraq. The analytical hierarchy process (AHP) technique was used to give relative weights to 12 contributing parameters, including elevation, slope, distance from the river, rainfall, land use land cover, soil, lithology, topographic roughness index, topographic wetness index, aspect, the sediment transport index, and the stream power index in order to calculate the Flood Hazard Index (FHI). The relative importance of each criterion was revealed by a sensitivity analysis of the parameter values. This research developed a final flood susceptibility map and identified high-susceptible zones. This was classified anywhere from very low to very high classifications for its potential flood hazard. The generated map indicates that 44.72 km2 of the total land area of the study area in Duhok city has a very high susceptibility to flooding, and that these areas require significant attention from government authorities in order to reduce flood vulnerability

Dziwaczne i osobliwe to zbiór esejów, w których autor dowodzi, że wiele spośród znanych dzieł kultury można opisać kategoriami dziwaczności lub osobliwości. Pojęcia te, choć bardzo do siebie zbliżone, nie są tożsame. Oba kojarzone są z horrorem lub literaturą sceince fiction, ale wykraczają poza jego ramy. Dotykają tego, co zewnętrzne i nieznane, niepokojące, ale niekoniecznie przerażające. Kategorie dziwaczności i osobliwości Fisher przykłada do dzieł takich twórców i twórczyń jak: H.P. Lovecraft, H.G. Wells, Daphne Du Maurier, Margaret Atwood, Stanley Kubrick czy Christoper Nolan. Ostatecznie otrzymujemy coś, co można by nazwać projektem "estetyki zewnętrza".

2023 Pełny tekst IEEE Access
Face masks are recommended to reduce the transmission of many viruses, especially SARS-CoV-2. Therefore, the automatic detection of whether there is a mask on the face, what type of mask is worn, and how it is worn is an important research topic. In this work, the use of thermal imaging was considered to analyze the possibility of detecting (localizing) a mask on the face, as well as to check whether it is possible to classify the type of mask on the face. The previously proposed dataset of thermal images was extended and annotated with the description of a type of mask and a location of a mask within a face. Different deep learning models were adapted. The best model for face mask detection turned out to be the Yolov5 model in the “nano” version, reaching mAP higher than 97% and precision of about 95%. High accuracy was also obtained for mask type classification. The best results were obtained for the convolutional neural network model built on an autoencoder initially trained in the thermal image reconstruction problem. The pretrained encoder was used to train a classifier which achieved an accuracy of 91%.
MASTERPLAN SKUTECZNYM NARZĘDZIEM PLANOWANIA DZIELNIC
- Weronika Mazurkiewicz
2023 Przegląd Komunalny
Przy równocześnie trwających pracach nad zmianą ustawy o planowaniu i zagospodarowaniu przestrzennym oraz niektórych innych ustaw wydaje się być zasadne poszukiwanie rozwiązań sprzyjających zahamowaniu dalszej degradacji przestrzeni niekoniecznie określonych ramami ustawowymi i prawem. Artykuł jest próbą ukazania zastosowania pozaustawowego dokumentu, jakim jest masterplan w polskich ramach planistycznych w celu kreowania spójnych wizji przestrzennych dla dzielnic i całościowych struktur przestrzennych. Od kilku lat toczy się dyskusja prowadzona przez samorządowców, urbanistów, środowiska naukowe, inwestorów i mieszkańców na temat zmian w systemie planowania przestrzennego oraz racjonalnej polityki przestrzennej w Polsce. Mamy też do czynienia zkryzysem przestrzennym narastającym od wielu lat, skutkującym m.in. rozlewaniem się miast, chaosem przestrzennym i rozproszeniem zabudowy, która często ma charakter niekompletny, gniazdowy i przypadkowy. Wydaje się, że propozycja zmiany ustawy o planowaniu i zagospodarowaniu przestrzennym w obecnej formie nie rozwiązuje wszystkich niedoskonałości prawa, szeroko komentowanych w ostatnich latach. Nie znaczy to jednak, że chaos przestrzenny musi dalej postępować. Jednym z rozwiązań stosowanych nieobligatoryjnie (niewymaganych ustawowo) jest stosowanie interdyscyplinarnych strategicznych dokumentów planistycznych, które określają zasady przygotowania i realizacji działań inwestycyjnych i nieinwestycyjnych. Wydaje się to być dobrym rozwiązaniem służącym kreowaniu elastycznych wizji rozwoju struktur przestrzennych oraz koordynacji kształtowania różnych dzielnic w mieście. Masterplan to najpopularniejsza nazwa dokumentu zawierającego kompleksową wizję danego terenu (spotykane nazwy narzędzi o podobnym zastosowaniu to m.in.: ministrategie rozwoju dzielnic, plany generalne dzielnic, strategie rozwoju dzielnic). Dokument ten od dawna jest stosowany w praktyce projektowej w Europie, w Polsce zaś stosunkowo krótko. Używane powszechnie za granicą nazwa, zawartość, forma oraz praktyka stosowania masterplanów to powód, dla którego w artykule wyróżniono tenże instrument spośród kilku innych o podobnym charakterze.
Materiały poliuretanowe o zmniejszonej palności otrzymane z udziałem biomasy ligninocelulozowej
- Kamila Gosz
2023 Pełny tekst
Poliuretany są uniwersalnymi materiałami inżynierskimi o szerokim zakresie zastosowań, ponieważ ich właściwości można łatwo regulować stosując różne kombinacje składników. W ostatnich latach dużą uwagę zwraca się na efektywne wykorzystanie surowców ze źródeł odnawialnych jako substytutów dla zasobów kopalnych. Wynika to nie tylko z obaw o przyszłe braki w dostawach ropy naftowej, ale również z powodu większego zapotrzebowania na produkty bardziej przyjazne środowisku. Upłynniona biomasa ligninocelulozowa jest bogata w grupy hydroksylowe i uważa się, że może stanowić potencjalny surowiec do przygotowania żywic poliuretanowych. Z drugiej strony poliuretany są materiałem łatwopalnym. Opracowanie żywicy poliuretanowej z wykorzystaniem biomasy ligninocelulozowej o zmniejszonej palności stanowi bardzo ważny aspekt społeczny. W przedstawionej rozprawie doktorskiej jako środki zmniejszające palność wykorzystano włókno bazaltowe w postaci maty i uniepalniacz z wysoką zawartością fosforu co pozwoliło uzyskać uniepalnione materiały poliuretanowe o zadawalających właściwościach mechanicznych.

We discuss here composite indicators as mathematical models, which can be looked at through the lenses of the five rules discussed in this volume. Composite indicators sit between analysis and advocacy, and their use has social and political implications. For this reason, the lenses of the manifesto can be used to build them better, to make them more transparent, as well as to inspect incumbent indicators for methodological or normative inadequacies.

2023 APPLIED SURFACE SCIENCE
Mono- (Co-BDC, Fe-BDC) and bimetallic FeCo-BDC Metal-Organic Frameworks are successfully synthesized by the solvothermal method in DMF at 150 °C within 15 h and tested as catalysts for sodium borohydride hydrolysis. The materials are characterized by FTIR, PXRD, TGA, ICP-OES, H2-TPR, BET model, and SEM-EDS. The catalytic activity of these materials is studied for dehydrogenation of sodium borohydride in water at various temperatures under basic conditions. Among tested catalysts, the most promising is Co-BDC, which provides hydrogen generation with a good rate of 1886.8 mL min−1 gcat−1 at 319 K and high efficiency (77.7 %) in the presence of a base. The activation energy determined as 25.4 kJ mol−1 is lower than most cobalt-bearing catalysts for NaBH4 hydrolysis described in the literature. The catalyst can be reused at least ten times, keeping a good overall hydrogen generation yield, and thus can be considered a promising candidate for portable hydrogen fuel systems.
Measuring the effectiveness of digital communication - social media performance: an example of the role played by AI-assisted tools at a university
- Edyta Gołąb-Andrzejak
2023 Pełny tekst
The aim of the article is to show the role played by AI-powered tools in measuring the effectiveness of digital communication in social media using a university case study. Therefore, a research problem was formulated to identify the metrics (KPIs) used to measure the effectiveness – non-financial outcomes – of digital social media communication at the university using AI tools. The literature review on the role of AI in digital marketing in social media showed that it is used, inter alia, to measure the effectiveness of digital communication – social performance. The importance of KPIs in digital marketing – indicators for measuring non-financial performance – and the presentation of tools used to analyse the effectiveness of social media campaigns were based on a case study of a higher education institution in Poland. With the application of AI tools (such as ContentStudio, HelloWoofy or Sotrender etc.), it is possible to automate analytical processes for KPIs such as reach, engagement, content or customer service, among others, as well as systematic reporting. This, in turn, provides opportunities to systematically monitor and make improvements to the implemented social media marketing communication strategy – to create a kind of Decision Support System (DSS) to support the aforementioned process. The study is introductory and exploratory in nature. It indicates the importance of tools using AI in business practice – using the case study of a university as an example.
