Authors: Bondaryeva Аnna , Zhaldak Maryna , Mokrousova Оlena , Okhmat Olena
Published: November 2022

The work is focused on obtaining nanopigments by adsorption of anionic dyes on positively charged montmorillonite. The effect of sequential modification of aqueous dispersions of montmorillonite with cationic and anionic compounds on the structural and charge characteristics of mineral dispersions was studied. The effect of chemical dispersion of agglomerates of aqueous montmorillonite dispersions after adding carbonate solutions was shown. The treatment of dispersions of original montmorillonite with sodium carbonate provides maximum dispersion of mineral aggregates by penetrating into the interstructural space of aluminosilicate packets, moving them apart and separating them. It was found that the modification of montmorillonite dispersed by sodium carbonate by adding basic chromium sulfate is accompanied by a change in the surface chemistry of the mineral and structural transformations. Structural changes are manifested by the formation of a developed structure of cationic montmorillonite. The cationic surface charge of montmorillonite and high specific surface of montmorillonite are important factors for ensuring effective adsorption of anionic dyes on the surface of the mineral. The efficiency of adsorption of anionic dyes on cationic montmorillonite is investigated. It was shown that the adsorption of dyes depended on the pH of the medium. The scheme of obtaining nanopigments, which were characterized by good сovering power, saturated and intense colour was proposed.

Published: November 2022

This study was carried out to determine influence of olive maturity on some physicochemical properties and fatty acid compositions of olive oils extracted from the Halhalı cultivar which harvested from Hatay in the Eastern Mediterranean region of Turkey. For this purpose, olive oils were obtained by mechanical method from olives collected from Halhalı cultivar in 3 different olive maturity of the 2021 production season. Ripening index and oil yield analysis of the olives and free fatty acids, peroxide value, fatty acid compositions were carried out in Halhalı olive oil. Free fatty acids and peroxide values of olive oils were found in the range of 0.39-0.73 (%oleic acid) and 5.14-9.43 meq O2/kg respectively. The amount of free fatty acids increased with maturity. It was determined that the oleic acid in the range of 67.59%-70.26%, palmitic acid in the range of 13.56-15.82%, linoleic acid in the range of 9.52-13.65%, stearic acid in the range of 3.34-4.13%, palmitoleic acid 0.96%-1.29%, linolenic acid 0.86-0.98% and arachidic acid 0.42-0.53. It was determined that decrease in oleic acid and palmitic acid contents and an increase in linoleic acid content with maturity. It has been determined that Halhalı monovarietal olive oil is within the limits specified in the Turkish Food Codex on Olive Oil and Pirina Olive Oil in terms of the examined properties.

Published: November 2022

Far infrared (FIR) functional textiles are a new category of functional textiles that have the potential to improve well-being and health. At the molecular level, FIR exerts strong rotational and vibrational effects with potential biological benefits. The majority of textiles with antimicrobial functionalization are based on synthetic products, and there is a need to link current end-user demands with both efficient products and low environmental impact, promoting natural antimicrobial treatments as viable solutions. Two structures of knitwear were obtained, with functional inorganic particles with antimicrobial, anti-UV and IR emission properties: variant 1: 100% BBC gauze ground yarn plated with functionalized polyamide yarn; variant 2: 85% wool/15% cashmere blend ground yarn plated with functionalized polyamide yarn. The antimicrobial efficiency of two types of functionalized materials was tested against six pathogenic microbial strains: Tricoderma viride (laboratory strain), Aspergillus flavus (laboratory strain), Candida albicans (ATCC 90028), Epidermophyton floccosum (CCM 8339), Trichophyton interdigitale (ATCC 9533) and Aspergillus niger (IMI 45551), highlighting various degrees of microbial reduction, depending on both the material and the tested strain, with lowest percentage microbial reduction of 9.67&, against Aspergillus niger strain, and highest of 86.65%, against Candida albicans.

Published: November 2022

The work is focused on obtaining collagen-based gel from leather waste with antimicrobial activity for further use with biomedical application and as dressings for wounds. Two antibiotics - macrolide azithromycin and phenicol chloramphenicol were tested using both laboratory strain and clinical isolates of Staphylococcus species from patients with wounds in Kyiv region. Collagen matrix was obtained from delimed pelt leather waste by acetic acid extraction. The biofilm assay and MTT assay were applied to study the effect of antimicrobial component in collagen-based gel. The reduced growth rate, cells attachment level and cells metabolic activity were the evidences of strains inhibition and biofilm development prevention.
Investigation of Acid Residue on the Surface of Dental Implants after Different Surface Cleaning Processes
Authors: Öztoprak Kaan , Öztoprak Ece
Published: November 2022

For dental implants to osseointegrate well, all clinical and production conditions must be perfect. Due to some negativities in production conditions, unwanted residual materials may remain on the implant surfaces, and these may adversely affect osseointegration. While producing implants, some surface treatments are required. These processes are generally based on the principle of increasing the surface area. Thus, they can provide attachment to the bone on more surfaces. Most methods applied to increase the implant surface area include acidic chemicals. After the acid is applied to the implant surfaces, the acid in the pits formed on the surface must be removed entirely. In cases where the acid cannot be completely removed, the remaining acid may cause bone destruction and cause implant loss. For this reason, some processes must be applied to remove residual acid. In this study, we aimed to find better ways to clean the acid residues on the implant surface. We created 2 groups of 20 implants in our study. Micro arc oxidation was applied with sulfuric acid in 2 groups and then washed with distilled water in a 180-watt ultrasonic cleaner. One group of implants was washed with pure water only, and the other group was washed with pure water and chemically neutralized. Sodium Bicarbonate 10% solution was prepared and washed for neutralization; the second group was kept in this solution for 10 minutes and washed with distilled water again. The implants in both groups were placed in 10cc ph7 distilled water and left for one day. After one day, the liquids were measured with a digital pH meter. In the measurement of the water in the group that was washed only with pure water, the average pH was 6.8, while the average pH of the water in the other group was 7. Our study concluded for the first time that basic neutralization on the implant surface could neutralize the acid residue in the microwells. We recommend chemical neutralization in implant manufacturing processes and think it can reduce implant failure rates.

Published: November 2022

This work concerns with obtaining and characterization of new hydrogels based on sodium alginate and gelatin in the form of cross-linked polymer networks, aimed at medical applications, for example controlled release of bioactive agents (pharmaceutical industry) and bioinks (regenerative medicine). Our synthesis strategy was based on the use of mild, ecological reaction conditions in the absence of crosslinking agents and organic oxidants. Only industrially available sodium alginate and gelatin from leather wastes, produced at micro-pilot level at INCDTP-ICPI, were used, without the presence of any additional crosslinking agents, to test their ability to form strong 3D gels. Tunable physical-chemical and mechanical properties of the hydrogels have were obtained by varying the ratio sodium alginate: gelatin. Newly synthesized hydrogels were characterized by both analytical methods, such as ATR-FTIR, TG-DTG and SEM, and standard tests for mechanical resistance.
Effective Biological Treatment of Tannery Wastewater from Nitrogen Compounds
Authors: Sabliy Larisa , Zhukova Veronika , Kika Lyubov
Published: November 2022

Even after using physico-chemical and biological methods, tannery wastewater still contains a large amount of nitrogen compounds, which reaches 90 mg/dm3. The ingress of such wastewater into natural reservoirs leads to eutrophication. The goal is to determine the efficiency of nitrogen compounds removal during sequential wastewater treatment in anaerobic, anoxic and aerobic bioreactors with immobilized microorganisms. For the study, wastewater from a tannery, collected after cleaning in aeration tanks, was used. Model solutions with a concentration of 18.4 - 90 mg/ dm3 were obtained by dilution. 5 sequential bioreactors were used - anaerobic (2 stages), anoxic (2 stages) and aerobic (1 stage) with a capacity of 125 ml/h. Microorganisms were immobilized in each bioreactor on artificial carrier. The effects of organic nitrogen removal in anaerobic bioreactors were 58-66%, anoxic 51-70%, aerobic 57, 5%. A decrease in the concentration of nitrogen compounds occurs as a result of the formation of N2, NH3 gases and the use of nitrogen by microorganisms for biomass growth. It is proposed that sequential treatment of tannery wastewater in anaerobic, anoxic, and aerobic conditions with immobilized microorganisms made it possible to obtain a high degree of nitrogen removal. The method does not require chemical materials and is ecological.

Authors: Duran Nizami
Published: November 2022

People apply a wide variety of over-the-counter treatments as food supplements against respiratory tract infections. In this study, we investigated the antiviral efficacy of piperine, capsaicin, and glycyrrhetinic acid (GA) against coronaviruses (SARS-CoV-2) and Influenza viruses (H1N1), which are associated with acute respiratory infections. TCID50 concentrations of SARS-CoV-2 and H1N1 isolates were determined. Then, the effectiveness of phytochemicals against these viral isolates at non-toxic concentrations was investigated. For this purpose, the MTT method and RT-PCR techniques were used. Non-toxic concentrations of Capsaicin, Piperine, and GA on Vero cells were determined as 0.625 µg/ml, and Ceramide at 1.25 µg/ml and lower concentrations. It was determined that Capsaicin and Piperine showed very significant antiviral activity against SARS CoV-2 when compared to standard drugs at concentrations of 0.312 µg/ml. The effectiveness of GA was determined to be lower (0.625 µg/ml) than these two phytochemicals. Capsaicin, piperine, and GA exhibited antiviral activity on SARS-CoV-2 and H1N1 viral replication, especially the activity of the combination of capsaicin plus piperine against SARS CoV-2 was stronger than the activity against N1N1 than against H1N1. In addition, it was determined that the triple combination of these components exhibited stronger antiviral activity than single and double combinations, resulting in a significant decrease in the number of viral copies. We think that this new formulation containing three different phytochemical compounds is effective against SARS-CoV-2 and influenza viruses, which are the most important causes of morbidity and mortality from respiratory tract viruses, and can be effective, especially for prophylactic purposes.

Published: November 2022

Streptococcus pyogenes, Streptococcus mutans, and Candida albicans are important human pathogens and their infections in the mouth, mouth, and throat are important. Prophylaxis against oral and respiratory tract infections is of great importance in terms of both reducing the use of antibiotics and lowering the infection frequency. This study investigated the antimicrobial activity of Capsaicin against S. mutans, C. albicans, and S. pyogenes. Non-cytotoxic concentration of Capsaicin was determined in the Vero cell line by the MTT method. Efficacy studies were performed within these determined non-cytotoxic concentrations. The efficacy of single and different combinations of these three biological components on cell adhesion and invasion. The non-toxic concentration of capsaicin on Vero cells was <1.35 µg/ml. Capsaicin exhibited significant antimicrobial activity against S. pyogenes, S. mutans, and C. albicans. Moreover, capsaicin was statistically significantly effective against host cell adhesion and invasion against S. mutans, S. pyogenes and C. albicans compared to the control group. The results showed that capsaicin is a highly potent antibacterial agent against S. pyogenes, and S. mutans, as well as an important prophylactic agent for fungal infections. As a result, we think that capsaicin is a useful molecule for the provision and maintenance of both respiratory diseases and oral health.

Published: November 2022

Emergency responders, due to the specifics of their work, are exposed to a combination of several different risks and there may be several possible consequences for their safety and health. The relative risk significantly influences the decisions regarding the compromise that must be made between the level of protection, functionality and comfort provided to the emergency worker. The aim of this research was to develop modular PPE systems that protect the emergency responders from injury while acting/ operating effectively in hazardous environments and provide the highest level of protection against a range of possible threats. The modular PPE system, built upon a duty uniform, integrates state-of-the-art protective technologies; provides basic protection from most likely threats (for example: fire, extreme weather etc.); enhances daily-wear comfort; provides increased localized protection as needed (for example: knees, forearms); includes next-to-skin layer and outer layer to provide varying levels of protection as needed; the modular layers easily donned and undonned. This modular approach: i) provides several advantages, including preserving comfort and flexibility until the intervention mission requires the use of the next level of protection; ii) it is a guarantee that emergency responders are not in a position of choosing between their safety and the effectiveness of the mission; iii) the use of modular layers could be the most cost-effective option, because only certain layers may become damaged or be in need of decontamination following an incident.

The work presents a series of aspects related to the degree of biodeterioration of some heritage objects made of inorganic substrates (brick), and the identification of fungi and bacteria with a damaging action on historical materials. Inorganic substrates represented by dust particles from walls and bricks were studied. Fired clay bricks can be severely affected by various macroscopic forms of degradation, as a consequence of chemical, physical-mechanical and biological degradation processes as a result of exposure to aggressive environmental agents. The samples studied (they were collected in compliance with conservation-restoration norms) are part of the “Small Cellar” of the Cotroceni Palace, one of the few spaces where the walls of the old foundation built by Șerban Cantacuzino between 1679-1681, are still preserved. By monitoring the microclimate parameters of the “small cellar” space, it was concluded that there is a greater variation of the relative humidity from 40% to 63%, but also of the temperature from 16℃ to 22℃, fluctuations due to the change of seasons. The samples taken, developed on the culture medium and isolated were analyzed from the point of view of microbiota, and the identified fungi mainly belong to the genera Mucor sp., Alternaria sp., Rhizopus sp., Fusarium sp. and Penicillium sp. Three different treatments, Clic, Q and Top Crete, were tested and applied on the wall by brushing. After 7 days, samples were collected and tested regarding microbial loading and the results are a proof of the treatment efficiency. The samples were further monitored from a microbiological point of view, but also from the point of view of the appearance given to the bricks after treatment (color change, brick texture, organoleptic properties, etc.).

Published: November 2022

Fabric phase sorptive extraction (FPSE) is a new-generation of sample preparation technique that effectively combines representative characteristics of solid-phase microextraction – SPME (equilibrium-based extraction) and solid phase extraction – SPE (exhaustive extraction). FPSE was introduced in 2014 by Kabir A. and Furon K.G. FPSE utilizes a fabric substrate (natural or synthetic such as cotton or polyester) that is chemically coated with a hybrid sorbent (organic-inorganic sol-gel). The entire assembly (fabric substrate coated with the sol-gel polymer) results in a fast and sensitive micro-extraction device. The FPSE development process can be described in 3 main steps: (1) Preparation of the fabric substrate for sol-gel coating, (2) preparation of the sol-solution for coating the substrate, and (3) formation of sol-gel coatings on the fabric substrate. Using this technique can be ensured a faster, cleaner, and with a high concentration of analyte solution. FPSE is a method that can be easily modified and used in different types of applications. For this reason, FPSE is increasingly used in the scientific community dealing with sample pretreatment. By using this technique, promising results have been obtained both for the extraction and determination of certain analytes from environmental samples, as well as from other types of samples, with complex matrices (food and biological samples). This study aims to summarize the existing data on FPSE and to briefly present this innovative method.

MUSEION project aims at developing an integrated IoT based platform for the sustainable management of environmental control and adaptation to climate change of museum collections. The MUSEION solution will thus provide the optimization of resources such costs, energy, staff workload, while contributing to carbon footprint reduction. This solution is a replicable IoT-based system, which will solve the problems of real objects in real conditions (sustainable environmental control and adaptation to climate change). It will consider the main components of the museum system that influence its optimal climate (i.e, museum itself, artworks and visitors) and will continuously monitor and allow visualization of environmental and air quality markers. The monitoring reports will be elaborated by a software designed to real-time calculate the overall Indoor Air Quality (IAQ) Index. The main advantage provided by the MUSEION system consist in the simultaneous monitoring and evaluation of the environment quality and its impact on various artefacts in various conservation condition.
El espacio físico en el proceso de reinserción social de menores infractores
Authors:   , Ortega-García Verónica
Published: November 2022

La investigación trata sobre uno de los espacios públicos menos tratados por los Estudios Urbanos: el espacio urbano donde se experimentan procesos de reinserción social de menores infractores, que pasaron por un periodo de confinamiento en ciertos centros de internamiento debido a la comisión de un delito tipificado por la ley. Se cuestiona si las características urbanas de los mismos (traza, configuración, capital edilicio, paisaje e imagen del lugar) influyen en la comisión de nuevos delitos, truncando la reinserción social programada por la reincidencia delictiva, por lo que acude a ciertas disciplinas que estudian las relaciones existentes entre las interacciones sociales que se dan en el espacio urbano con el medio ambiente (natural o construido), tales como Psicología Social, Psicología Ambiental, Criminología Ambiental, Neuropsicología, Estudios Jurídicos, Sociología, Antropología y Diseño Urbano (Urbanismo), así como el seguimiento de tres estudios de caso protagonizados por adolescentes en conflicto con la ley. Concluye que el espacio por sí mismo no logra explicar la motivación de la reincidencia delictiva en tanto no hay espacio urbano sin interacciones sociales, pues son estas las que explican con mayor precisión que el adolescente infractor reincida nuevamente. Durante el desarrollo de la investigación la autora tuvo oportunidad de trabajar en otros espacios en conflicto, por lo general invisibles a la investigación académica, como lugares segregados por el narcotráfico o de reclusión, como ciertos centros de atención de migrantes en zonas fronterizas de Panamá y de México, que enriquecieron sus análisis y apreciaciones sobre el tema.

The aim of investigation was to address the impacts of tropical forests conversion into agricultural land on changes in Oribatid mites’ communities as well as soil physico-chemical properties across 2–4 texturally distinct soils in La Mé and Grand Lahou, Côte d’Ivoire. The fieldwork was conducted in the humid period on two study sites: 1– rubber landscape (secondary forest, 7-, 12- and 25-year-old rubber plantations) and 2– oil palm landscape (secondary forest, 13-, 20- and 39-year-old oil palm plantations). Three sampling areas were established on each land-use type and age class, for a total of 24 sampling areas. In each sampling area, soil cores for Oribatid mite’s extraction were taken at a depth of 10 cm across a 40–50 m transect. The soil physical and chemical properties were also measured. The results showed a decrease in Oribatid density (–29% and –71%), species richness (–29% and –42%), diversity (–29% and –59%), soil organic carbon (–56% and –17%), total nitrogen (–55% and –12%) and soil organic matter (–56% and –17%), and an increase in bulk density (+28% and +21%), respectively after the conversion of the secondary forests into rubber and oil palm plantations. Whatever the study site, the soil physico-chemical and biological properties were more stabilized in the clay and clay sandy textures compared to sandy clay and sandy soil textures. Our findings suggest the incorporation of woody trees with an understory of nitrogen-fixing legume species as a cover crop, which can create a sustainable agroforestry system with improved land quality.

Applying Psychological and Educational Health Models to Determine the Effect of Cognitive and Behavioral Interventions on Tuberculosis Treatment Outcomes in Plateau State, Nigeria
Authors: Sariem Comfort Nanbam , Dapar Maxwell Patrick , Lenka Nenman Musa , Kolawole Jacob , Aguiyi John
Published: November 2022

Background: The prolonged multi-drug treatment regimen for tuberculosis (TB) can lead to non-adherence and unsuccessful treatment outcomes. Educational and psychological health models can be used to design cognitive and behavioral interventions to improve adherence and treatment outcomes.
Objective: To determine the effect of cognitive and behavioral interventions on TB treatment outcomes.
Methods: The quasi-experimental study conducted in six TB treatment centers involved reinforced medication education and adherence counseling (MEAC), designed from a structured validated psychometric scale. Data were collected three different times during the intensive and continuation phases of treatment from 463 TB patients (232 in the control and 231 in the intervention group). Baseline demographic and clinical characteristics were compared between the groups. The generalized estimating equation model was used to analyze the repeated measures by determining if treatment success was associated with the cognitive and behavioral interventions and medication adherence.
Results: The males made up 290(62.6 %) of the population. The mean age was 36.75±13.9. Most of the TB patients were newly diagnosed 413(89.2%) and HIV negative 315(68%), with secondary level of education 216(46.6%). There was no significant difference in baseline characteristics between the groups. The intervention group was four times more likely to have treatment success (p<0.01; CI=1.5-8.4), compared to the control group. Medication-adherent TB patients were 24 times more likely to have treatment success than patients who did not adhere (p<0.001; 10.8-52.1). TB patients’ emotions, attitudes, and perceptions of their medicines were predictors of treatment success (p<0.05; 1.0 – 1.1).
Conclusion: The cognitive and behavioral interventions administered to TB patients improved successful treatment outcomes.
Uncertainty or Indeterminacy? Reconfiguring Curriculum through Agential Realism
Authors: Bozalek Vivienne
Published: November 2022

Understanding how indeterminacy is different from uncertainty is crucial to posthumanism and has major implications for reconfiguring curriculum. Uncertainty has to do with epistemology, about not knowing whether a state of affairs is or is not; for instance, one would not know whether something is here or there, now or then. Indeterminacy, however, is ontological and eschews the idea of individually existing determinate entities, proposing instead phenomena-in-their-becoming and a radically open relating of the world. Karen Barad, a feminist queer theorist, uses Niels Bohr’s quantum physics to show how atoms possess an inherent indeterminism or lack of identity in space and time. Indeterminacy is thus an un/doing of identity that unsettles the very foundations of being and non-being. Furthermore, neither space nor time are predetermined givens, but come into being intra-actively through the emergence of phenomena. This article shows how an understanding of space/time indeterminacy is important for thinking otherwise in curriculum studies.

Rozważania dotyczą popularności zabiegu wazektomii na świecie, a w szczególności w Wielkiej Brytanii. Poruszane zostają aspekty kulturowe, moralne, prawne i medyczne. Analizowane są różnice opinii wobec kontroli urodzeń, polityki demograficznej, oraz możliwości samodzielnego decydowania o sobie. Artykuł dotyka stereotypów związanych z płodnością, męskością, równouprawnieniem płci; analizuje korzyści i straty ekonomiczne i zdrowotne związane z zabiegiem wazektomii. Poszukiwane są powody popularności tej metody antykoncepcyjnej. W kontekście rosnącej wolności obyczajowej można zadać pytania: czy wybór wazektomii świadczy o nastawieniu współczesnego człowieka na seksualną wolność i niekontrolowanie Freudowskich popędów? Czy też jest racjonalną przemyślaną decyzją w trosce o zdrowie i zwiększoną wolność wyboru kobiet?

Przedmiotem niniejszego artykułu jest analiza i krytyka nurtu w teorii polityki zwanego nowym kosmopolityzmem. W przedstawionej interpretacji projekty nowego kosmopolityzmu stanowią z jednej strony ilustrację poświadczającą współczesną problematyczność demokracji, a zarazem nowatorską próbę redefinicji pojęcia demokracji przez nadanie temu pojęciu nowych wymiarów i nowej dynamiki. Wprowadzone przez nas pojęcie „minimum kosmopolitycznego” służy nam jako narzędzie meta-teoretyczne i metodologiczne, za pomocą którego argumentujemy na rzecz tezy, że na obecnym etapie nie da się wskazać minimalnego zestawu twierdzeń i zaleceń praktycznych, które można by uznać za obszar zgody i porozumienia między rywalizującymi podejściami i teoriami nowego kosmopolityzmu. W szczególności analiza tego nurtu wskazuje, że dotychczasowe sformułowania idei polityki kosmopolitycznej oraz jej możliwe praktyczne realizacje, jak dotąd nie zaowocowały ustaleniem „minimum kosmopolitycznego”, które mogłoby stanowić podstawę ich przyszłego powodzenia. Sugerujemy, że właściwą metodą dążenia do ideałów kosmopolitycznych jest formułowanie ich w sposób kosmopolityczny i demokratyczny zarazem, a więc z udziałem tych, których głos był dotychczas pomijany.
Analiza krytyczna wybranych pozostałości nazizmu w systemie społeczno-politycznym i prawnym Republiki Federalnej Niemiec
Authors: Zamana Jakub , Jartyś Janusz
Published: November 2022

Celem niniejszego artykułu jest przedstawienie krytycznej analizy wybranych pozostałości nazizmu w Republice Federalnej Niemiec (RFN). Pozostałości nazistowskiego systemu przez lata były tolerowane, a nawet chronione przez aparat państwowy RFN w niemal wszystkich dziedzinach życia. Zachodzi zatem pytanie o skuteczność przeprowadzonej po II wojnie światowej denazyfikacji i zmiany mentalności znacznej części niemieckiego społeczeństwa. Należy bowiem zauważyć, że z niektórymi pozostałościami hitlerowskiego systemu Republika Federalna Niemiec pożegnała się dopiero w XXI wieku i tym samym nie zdołała do chwili obecnej zadośćuczynić wszystkim jego ofiarom. Autorzy ukażą również fakt, że w posttotalitarnym państwie bardzo trudno jest znaleźć tak zwane „nieskazitelne życiorysy” biorąc pod uwagę ilość byłych członków NSDAP, którzy przez lata sprawowali wysokie urzędy w RFN.
O kontroli zmysłowości i dostępie do toalet publicznych
Authors: Kostecka Marianna
Published: November 2022

Celem niniejszej pracy jest umieszczenie zjawiska toalety publicznej w dwóch kontekstach: 1. historyczno-kulturowym, związanym z analizowanym przez Norberta Eliasa przesuwaniem się progu wstydu, cywilizacyjnymi przemianami o charakterze psycho i socjogennym; 2. socjologiczno-ekonomicznym, dotyczącym dostępności toalet publicznych, mającej wpływ na regulowanie tego kto, gdzie i kiedy może z nich korzystać. W częoeci pierwszej do analizy wybranych zagadnień zostały wykorzystane m. in. koncepcje psychoanalityczne i antropologiczne, w szczególnooeci jednak teoria czystości i brudu Mary Douglas. Częość druga została pooewięcona rozważaniom na temat sytuacji konkretnych grup społecznych, tj. bezdomnych, ulicznych handlarzy i handlarek, taksówkarzy i taksówkarek, dla których kwestie dostępności toalet publicznych uważa autorka za wyjątkowo istotne, bowiem mające wpływ zarówno na poziom ich dobrobytu, jak i dobrostanu psychicznego.

Authors: Winczewski Damian
Published: November 2022

Celem artykułu jest prezentacja i krytyczne omówienie poglłdów generała Carla von Clausewitza, na temat polskiej niepodległości oraz samych Polaków. W tym celu została wykorzystana dostępna literatura żródłowa w postaci jego głównej pracy, którą jest traktat O wojnie oraz szeregu nieznanych szerzej pism wojskowych, politycznych i historycznych. Wykorzystane zostały również wybrane fragmenty korespondencji oraz opinie uznanych autorów z literatury przedmiotu. Konkluzją jest stwierdzenie, że negatywna opinia Clausewitza na temat polskiej niepodległości wynika z konkretno-historycznej analizy podyktowanej wiernością autora pruskiej racji stanu.

Authors: Nireeksha B. N. , Harsha P , Naik Balaram D , Setty Swati , Horatti Priya
Published: November 2022

The progressive breakdown of mineralized tooth tissue caused by overactive resorptive cells is known as root resorption. Root resorption can be divided into two types: Normal and pathologic. In most of cases of internal resorption and external inflammatory resorption root canal therapy is indicated. It may or may not be indicated in cases of invasive resorption, and it is not suggested in cases of replacement or pressure resorption (unless unrelated pulpal conditions necessitate endodontic intervention). Early detection and treatment of these defects might be beneficial to the patient and increase the chances of saving the tooth. In this case, report the description of external resorption post-orthodontic treatment has been restored and followed up and has shown a good prognosis.

Authors: Dutton Jason , Sharp-Bucknall Lachlan , Sceney Marcus , White Keith
Published: November 2022

Both mixed λ3-iodoarenes and λ3-iodoarenes possessing -OTf ligands are coveted for their enhanced reactivities. Here we describe the synthesis, reactivity, and comprehensive characterisation of two new ArI(OTf)(X) species, a class of compound that were previously only invoked as reactive intermediates where X= Cl, F and their divergent reactivity with aryl substrates. A new catalytic system for electrophilic chlorination of deactivated arenes using Cl2 as the chlorine source and ArI/HOTf as the catalyst is also described.
Photocatalytic oxygen transfer as an innovative route for N2O upgrading
Authors: DELAUNAY Oriane , ZGHAB Eya , Denicourt-Nowicki Audrey , ROUCOUX Alain
Published: November 2022

As concentration of nitrous oxide (N2O) keeps growing steeply in the atmosphere, upgrading this anthropogenic greenhouse gas as a potential oxygen transfer agent constitutes a real challenge to limit global warming and ozone layer depletion. Decomposition of N2O is mainly described under highly energy-consuming thermal activation, owing to its high stability and large activation barrier, making it kinetically inert. Herein, we demonstrate the controlled photocatalytic upgrading of N2O as an oxygen atom donor, releasing only dinitrogen (N2) as a benign co-product. The doped Ag@TiO2 photocatalyst specifically activates N2O for controlled oxidation of phosphines avoiding mineralization, under mild conditions, as a proof-of-concept of the valorization of N2O as an oxygen transfer agent. The catalytic system is active and selective in various organic solvents, as well as innovatively in water, depending on the phosphine structure.

Published: November 2022

Herein, we report the synthesis, isolation and characterization of two cationic organobismuth(II) compounds bearing N,C,N pincer frameworks, which are crucial intermediates in bismuth radical processes. X-ray crystallography uncovered a monomeric Bi(II) structure, while SQUID magnetometry in combination with NMR and EPR spectroscopy provide evidence for a para-magnetic S = 1/2 state. High resolution multifrequency EPR at X, Q, and W-band enable the precise assignment of the full g- and 209Bi A-tensors. Experimental data and DFT calculations reveal both complexes are metal-centered radicals with little delocalization onto the ligands.
Rapid Adsorption Enthalpy Surface Sampling (RAESS) to Characterize Nanoporous Materials
Authors: Ren Emmanuel , Coudert François-Xavier
Published: November 2022

Molecular adsorption in nanoporous materials has many large-scale industrial applications ranging from separation to storage. To design the best materials, computational simulations are key in guiding the experimentation and engineering processes. Because nanoporous materials exist in a plethora of forms, we need to speed up the existing simulation tools to be able to screen databases of hundreds of thousands structures. Here, we describe a new algorithm that quickly calculates adsorption enthalpies by sampling the surface of the material instead of the whole porous space. This surface sampling has been tested on the CoRE MOF 2019 database and has been proven to be more than 2 orders of magnitude faster than the gold standard method (Widom insertion), with an acceptable level of error on the enthalpy value of 0.34 kJ/mol, and is therefore proposed as a valuable addition to the high-throughput screening toolbox.
Vanadyl as a Spectroscopic Probe of Tunable Ligand Donor Strength in Bimetallic Complexes

Published: November 2022

Incorporation of secondary metal ions into heterobimetallic complexes has emerged as an attractive strategy for rational tuning of compounds’ properties and reactivity, but direct solution-phase spectroscopic interrogation of tuning effects has received less attention than it deserves. Here, we report assembly and study of a series of heterobimetallic complexes containing the vanadyl ion, [VO]2+, paired with mono-valent cations (Cs+, Rb+, K+, Na+, and Li+) or a di-valent cation (Ca2+). These complexes, which can be isolated in pure form or generated in situ from a common monometallic vanadyl-containing precursor, enable experimental spectroscopic quantification of the influence of the incorporated cations on the properties of the vanadyl moiety. The data reveal systematic shifts in the V–O stretching frequency and isotropic hyperfine coupling constant for the vanadium center in the complexes. These shifts can be interpreted as charge density effects parametrized through the Lewis acidities of the cations, suggesting broad potential for the vanadyl ion to serve as a spectroscopic probe in multimetallic species.
