Мета роботи: проблематика тематичного та жанрового репертуару в живописі жінок-художниць у контексті формування модерністичного обличчя китайського образотворчого мистецтва першої половини ХХ ст. Методологія. У дослідження застосовані методи історико-хронологічного та компаративного аналізу. Для інтерпретації творів мистецтва використано метод образно-стилістичного аналізу. Наукова новизна. Дослідження дозволило виявити та показати особливу роль своєрідної жанрової форми «прихованого» автопортретування (Панг Юліан, Сун Дуочі). Уточнено та розширено значення жанру натюрморту, який використовувався жінками-художницями не тільки як певний засіб демонстрації майстерності роботи в олійній техніці, але як простір експериментування із західними стилістичними художніми мовами: передусім, фовізму, постімпресіонізму та експресіонізму. Висновки. На основі вивчення живописних творів китайських мисткинь показано формування модерністичного обличчя жіночого живопису в Республіканському Китаю першої половини ХХ ст. Виявлено, що процеси становлення модернізму відбувалися на ґрунті своєрідності тематичного та жанрового репертуару. Особлива роль образної репрезентації мисткинь спонукала до більш активної роботи в жанрі автопортрету. Важливою темою у творчості китайських художниць стала жіноча тілесність, репрезентована як в манері написання оголеної натури (наприклад, у жанрі ню в роботах Фан Цзюньбі), так і в формі представлення жіночої образності в жанровій картині та портреті. Практичне значення. Введені до наукового обігу дослідження китайських вчених можуть бути використані для подальшого дослідження проблематики жіночого живопису і мистецтва наступних часів, науково-практичної підтримки широких гендерних досліджень.

Authors: Yaghoubian Ali , Hodgson Gregory K. , Adler Marc J. , Impellizzeri Stefania
Published: June 2024

We report on a direct photochemical method for the one-pot, catalyst- and additive-free synthesis of azoxybenzene and substituted azoxy derivatives from nitrobenzene building blocks. This reaction is conducted at room temperature and under air, and can be applied to substrates with a wide range of substituents. Yields of products derived from para- and meta-substituted nitrobenzenes are typically good, while sterically encumbered ortho-substituted substrates are not as fruitful. Photochemical Wallach rearrangement of generated azoxybenzenes to ortho-hydroxyazoxybenzenes was observed in some cases, most markedly in selected ortho-halogenated nitrobenzenes. Overall, this method provides an efficient, green pathway to highly value-added azoxybenzene products.
Experimental Investigation of Heat Transfer with Various Aqueous Mono/Hybrid Nanofluids in a Multi-Channel Heat Exchanger
Authors: Plant Robert , Hodgson Gregory , Impellizzeri Stefania , Saghir M. Ziad
Published: June 2024

The use of nanofluids for heat transfer has been examined in recent years as a potential method for augmentation of heat transfer in different systems. Often, the use of nanoparticles in a working fluid does not disrupt the system in significant ways. As a result of this general improvement of a system’s heat transfer capabilities with relatively few detrimental factors, nanofluids and hybrid nanofluids have become an area of considerable research interest. One subcategory of this research area that has been under consideration is the concentration of each of the nanoparticles, leading to either successful augmentation or hindrance. The focus of the current experimental investigation was to examine the resulting impact on heat transfer performance as a result of each nanofluid implemented in an identical three-channel heat exchanger. This work examined the experimental impacts of 0.5 wt% titania (TiO2), 1 wt% titania, a mixture of 0.5 wt% titania and 0.5% silica, and a 0.5 wt% hybrid nanofluid of titania synthetically modified with copper-based nanostructures (Cu + TiO2). The experimental work examined a range of heat flux densities from 3.85 W cm−2 to 7.51 W cm−2, and varying flow rates. Each of the nanoparticles were suspended in distilled water and then mixed using an ultrasonic water bath. The performances of each nanofluid were determined using the local Nusselt number to evaluate the possible thermal enhancement offered by each nanofluid mixture. While the 0.5 wt% Cu + TiO2 hybrid nanofluid did significantly increase performance, the use of a 0.5 wt% TiO2/SiO2 double nanofluid in a three-channel heat exchanger exhibited the greatest performance enhancement, with an average increase of 37.3% as compared to water.
A Redox-Driven Multicomponent Molecular Shuttle

Published: June 2024

A multicomponent [2]rotaxane designed to operate as a molecular shuttle driven by light energy has been constructed, and its properties have been investigated. The system is composed of (1) a light-fueled power station, capable of using the photon energy to create a charge-separated state, and (2) a mechanical switch, capable of utilizing such a photochemically generated driving force to bring about controllable molecular shuttling motions. The light-fueled power station is, in turn, a dyad comprising (i) a π-electron-accepting fullerene (C60) component and (ii) a light-harvesting porphyrin (P) unit which acts as an electron donor in the excited state. The mechanical switch is a redox-active bistable [2]rotaxane moiety that consists of (i) a tetrathiafulvalene (TTF) unit as an efficient π-electron-donor station, (ii) a dioxynaphthalene (DNP) unit as a second π-electron-rich station, and (iii) a tetracationic cyclobis(paraquat-p-phenylene) (CBPQT4+) π-electron-acceptor cyclophane, which encapsulates the better π-electron-donating TTF station. Diethylene glycol spacers were conveniently introduced between the electroactive components in the dumbbell-shaped thread to facilitate the template-directed synthesis of the [2]rotaxane. A modular synthetic approach was undertaken for the overall synthesis of this multicomponent bistable [2]rotaxane, beginning with the syntheses of the P−C60 dyad unit and the two-station TTF−DNP-based [2]rotaxane separately, using conventional synthetic methodologies. These two components were finally stitched together by an esterification to afford the target rotaxane. Its structure was characterized by 1H NMR spectroscopy and mass spectrometry as well as by UV−vis−NIR absorption spectroscopy and voltammetry. The observations reflect remarkable electronic interactions between the various units, pointing to the existence of folded conformations in solution. The redox-driven shuttling process of the CBPQT4+ ring between the two competitive electron-rich recognition units, namely, TTF and DNP, was investigated by electrochemistry and spectroelectrochemistry as a means to verify its operational behavior prior to the photophysical studies related to light-driven operation. The oxidation process of the TTF unit is dramatically hampered in the rotaxane, thereby reducing the efficiency of the shuttling motion. These results confirm that, as the structural complexity increases, the overall function of the system no longer depends simply on its “primary” structure but also on higher-level effects which are reminiscent of the secondary and tertiary structures of biomolecules.

Published: June 2024

Aims of the study: Achyranthes aspera (Family: Amaranthacea) is a medicinal plant used as an anti-cancer agent in ayurveda, a traditional system of medicine practiced in subcontinental India. The aim of the study was to systematically investigate the anti-proliferative properties of Achyranthes aspera leaves extracted in methanol (LE) on human cancer cells in vitro.

Materials and methods: We tested time, dose dependent and specific anti-proliferative activity of LE by clonogenic cell survival assay on human cancer and normal epithelial cell lines in vitro. We further investigated its effect on the expression of metastatic and angiogenic genes by real time polymerase chain reaction. On silica gel column, we carried out initial fractionation analysis.

Results: LE exhibited time and dose dependent cytotoxicity on several tumor cells. Compared to cancer cells of colon, breast, lung and prostate origin, pancreatic cancer cells were significantly more sensitive to LE. Preliminary mechanistic studies suggested that LE selectively suppressed the transcription of metalloproteases (MMP-1 and -2), inhibitors of MMPs (TIMP-2) and angiogenic factors (VEGF-A and VEGF-B). Fractionation of LE on methanol equilibrated silica gel column resolved into three fractions of which fraction (F 3) was found to be enriched with anti-proliferative activity.

Conclusion: Methanolic extract of Achyranthes aspera contains potent anti-proliferative compound with specific activity against pancreatic cancer. Further studies are needed to confirm the in vivo anti-tumorigenicity and subsequent chemical characterization of the active molecule(s).
A photoswitchable bichromophoric oxazine with fast switching speeds and excellent fatigue resistance
Authors: Deniz Erhan , Impellizzeri Stefania , Sortino Salvatore , Raymo Françisco M.
Published: June 2024

In search of strategies to regulate the photochemical and photophysical properties of photochromic oxazines, we designed a multichromophoric compound incorporating 3H-indole, benzooxazine, and 2-(4-dimethylaminophenyl)ethynyl fragments. We synthesized this molecule in two steps in an overall yield of 51%, starting from commercial precursors. The ultraviolet irradiation of this photochrome opens a [1,3]oxazine ring in less than 6 ns to generate a zwitterionic isomer with a quantum yield of 0.10. In particular, the photoinduced ring opening generates a 4-nitrophenolate anion and a 3H-indolium cation. Additionally, this process brings the 2-(4-dimethylaminophenyl)ethynyl appendage into conjugation with the 3H-indolium cation. As a result, two distinct bands for the anionic and cationic fragments of the photogenerated zwitterion appear in the visible region of the absorption spectrum. The photogenerated isomer has a lifetime of 2 µs and switches back to the original form with first-order kinetics. Furthermore, this bichromophoric photochrome tolerates hundreds of switching cycles with no sign of degradation and can be operated within rigid polymer matrices. Thus, this particular structural design can lead to the development of a new family of bichromophoric photochromes and photoresponsive materials with microsecond switching times and excellent fatigue resistances.

Published: June 2024

Solid niobium oxides (Nb2O5·nH2O) and niobium phosphate were used as heterogeneous acid catalysts to promote the condensation between a switchable oxazine and a fluorescent coumarin in an aprotic solvent. The catalysts were found to promote the generation of an active methylene from the enamine-based portion of the oxazine, which was followed by a nucleophilic attack on the aldehyde functionality of the coumarin reagent. In the resulting system, the emission of the conjugated fluorophore can be observed at 670 nm and, thus, the processes occurring at the catalyst surface can be monitored in real time by total internal reflection fluorescence microscopy (TIRFM).

Visible-light excitation of the surface plasmon band of silver nanoplates can effectively localize and concentrate the incident electromagnetic field enhancing the photochemical performance of organic molecules. Herein, the first single-molecule study of the plasmon-assisted isomerization of a photochrome-fluorophore dyad, designed to switch between a nonfluorescent and a fluorescent state in response to the photochromic transformation, is reported. The photochemistry of the switchable assembly, consisting of a photochromic benzooxazine chemically conjugated to a coumarin moiety, is examined in real time with total internal reflection fluorescence microscopy in the presence of silver nanoplates excited with a 633 nm laser. The metallic nanostructures significantly enhance the visible light-induced performance of the photoconversion, which normally requires ultraviolet excitation. The resulting ring-open isomer is strongly fluorescent and can also be excited at 633 nm. These stochastic emission events are used to monitor photochromic activation and show quadratic dependence on incident power. The utilization of a single laser wavelength for both photochromic activation and excitation effectively mimics a pseudo two-colours system.

Influence of intermittent stream dynamics on predator-prey interactions
Authors: Gonçalves-Silva Milena , D'Bastiani Elvira , Datry Thibault , Rezende Carla
Published: June 2024

Intermittent rivers and ephemeral streams are dynamic ecosystems characterized by periodic interruptions in flow, leading to temporary or complete absence of water. These dynamics create a mosaic of isolated pools, reducing habitat volume and connectivity, and impacting resource availability and predation levels. This study addresses three key questions: (i) Do species composition and environmental variables change during the hydrological phases in intermittent streams? (ii) Do hydrological phases in intermittent streams affect predator-prey network structures? (iii) Do stochastic factors during the dry phase affect predator-prey network structures? We analyzed predator-prey interactions using fish food items along 1 km of the intermittent river Tabocas during flowing (23 sections) and dry (22 isolated pools) phases, identifying 18 predator species and 11 ecological categories of food items. Our results indicate that fish species composition and environmental variables shift between flowing and dry phases. Despite similar richness, significant differences in fish species composition underscore the importance of temporal fluctuations in community dynamics. Hydrological fluctuations notably affect predator-prey network structures. During the flowing phase, interaction networks exhibited a nested pattern. In contrast, the dry phase networks within isolated pools displayed diverse patterns, including nested, modular, highly specialized, and random structures. Stochastic factors during the dry phase contribute to the formation of isolated pools, leading to predator-prey networks with random structures. The reduction in predator-prey links and increased specialization within pools are key factors contributing to the emergence of random networks, making fish species more vulnerable. Our findings emphasize the importance of identifying priority aquatic refuges to sustain freshwater biodiversity in intermittent streams. Considering hydrological variability and stochastic factors is crucial in devising conservation strategies to mitigate the impact of climate change on the biota of tropical semi-arid ecosystems.
Metadiscursive Markers Across Three Feminist Waves: A Sociolinguistic Study
Authors: Naderi Javad , Asadi Shahrbanoo
Published: June 2024

To investigate the variance in the use of metadiscursive markers by female authors through the different stages of the feminist movement, this study cross-examined the use of metadiscursive hedges and boosters as defined by Hyland’s metadiscourse model in Mary Wollstonecraft’s A Vindication of the Rights of Woman, Virginia Woolf’s To the Lighthouse, and Luce Irigaray’s The Sex Which Is No One, respectively corresponding the three feminist waves. All samples of the said markers were collected among which those used to metadiscursive effects were identified by two raters. The proportions and frequency of the use of both markers were determined and analyzed within samples and between samples. The results of a Chi-Square test showed a significant difference in the use of both hedges and boosters within each work and between them. The data indicated that all three authors used metadiscursive hedges significantly more frequently than metadiscursive boosters. The results also revealed that there was a significant increase in the frequency of hedges moving from the first wave to the second but a slight decrease in moving from the second to the third wave, which shows that the increase was maintained. The data also showed a consistent significant increase in the frequency of boosters from the first wave to the second and from the second to the third. The findings suggest that in the course of the feminist movement, female authors have increasingly made bolder and firmer statements and claims in their works while simultaneously using a more cautious style to mitigate the boldness of their claims and more efficiently influence their readers.

Published: June 2024

Aunque en Colombia la ausencia de regulación sobre la disponibilidad jurídica del cuerpo humano o partes de este, es una realidad, existe una legislación básica sobre algunos temas que han sido desarrollados por la ciencia médica, como lo es la donación de órganos, se plantea como problema jurídico: ¿Existe en el ordenamiento jurídico colombiano fundamentos legales, jurisprudenciales o principialistas que permitan o prohíban la disponibilidad jurídica del cuerpo humano y partes separadas de éste, en respuesta a los avances científicos propiciados por la ciencia médica ( en este caso circunscrito al trasplante y donación de órganos) ?; por tal motivo se analizará a manera de reflexión crítica, algunos aspectos jurídicos sobre la donación de órganos en Colombia, y la reglamentación de la misma en línea de tiempo, así como su diferencia con la presunción legal de donación de órganos, en especial a la luz de la ley 1805 de 2016, planteando argumentos que establecen críticas a  los mecanismos legales que la ley contempla para la declaración de voluntad en tal sentido; dándole un matiz de actualidad con la introducción de la figura de  directivas anticipada a la luz  de la ley 1996 de 2019 en Colombia. Para finalmente concluir que es necesario una reglamentación sistemática y actualizada pero coherente sobre la disposición del cuerpo humano, en este caso, de partes separadas del cuerpo humano, como lo son los órganos.

Organic compounds are compounds whose constituents consist of carbon and hydrogen atoms, oxygen, nitrogen, sulfur, halogen or phosphorus. Organic compounds are also known as secondary metabolics. While secondary metabolic compounds are compounds that are not evenly distributed in living things and are only found in small amounts. Generally found in plant organs (especially tall plants) in the roots, skin, stems, leaves, fruit and seed flowers and a little in animals. Organic compounds can be broken down into carbon dioxide (CO2), ammonia gas and other compounds to be simplified. The decomposing bacteria commonly found can act as decomposers of organic compounds. These bacteria play a role in the cycle of organic elements in a biosphere. The purpose of this research is to find the character of the types of bacteria that can break down or degrade organic compounds. Bacteria that were isolated and identified came from the digestive tract bacteria of native chicken taken from cache, proventriculus, gizzard and intestine. Bacterial isolation method used is the method of sprinkling or pouring on selective media. The test was conducted to see the type and character of bacteria that can degrade cellulose, pectin and starch mixed with MRSA (Man ragosa sharpe agar) media. Isolates that show activity on cellulose, pectin and starch are characterized by clear zones around the colony. Identification was carried out on isolates that showed the highest clear zone index based on the results of testing the activity of cellulose, pectin and starch. In this study there were 15 bacterial isolates which were isolated, 2 isolates from cache, 5 isolates from proventiculus, 5 isolates from gizzard and 3 isolates from intestine. Among these isolates were found 4 types of bacterial characteristics of coccus and 11 types of bacterial bacterium characters.

This study aims to find one type of planting media that has a good effect on the proliferation of mycorrhizae using soybean host plants and to determine the effect of various types of planting media on the growth of soybean host plants. This research was conducted at the Greenhouse of the Faculty of Agriculture, Indonesian Muslim University, Makassar. Soil sample analysis was carried out at the Laboratory of Soil and Conservation, Faculty of Agriculture, Muslim University of Indonesia. Analysis of root infection samples and the number of spores at the Microbiology Laboratory, Research and Development Center for the Environment and Forestry. The study started from April to August 2021. This study used a completely randomized design consisting of four treatments, namely soil, soil + husk volume (2:1), soil + burnt husk (2:1), soil + husk + husk burn volume (2:1/2:1/2). Each treatment was repeated 3 times so that 12 experimental units were obtained and each experimental unit used 3 polybags so that there were 36 polybags. The results showed that the use of planting media consisting of soil + husk volume (2:1) obtained a higher percentage of AMF infection (76.11%), then a higher number spores with soil  that is (56.00). The best soybean host plant growth was on soil + husk fuel volume (2:1), which was shown by taller plants and more leaves.

This study aims to determine the effect of various types of planting media on the propagation of mycorrhizae, the effect of the type of host plant on the propagation of mycorrhizae, and to determine the effect of the interaction between the planting medium and the host plant on the propagation of mycorrhizae. This research was conducted at the Green House, Faculty of Agriculture, Indonesian Muslim University, Makassar City, South Sulawesi. This study used a randomized block design with a two-factor factorial pattern. The first factor is the influence of growing media which consists of three levels of treatment, namely; land; soil+husk (2:1); soil+husk charcoal (2:1), and the second factor is the type of host plant which consists of two types, namely: corn plants and sorghum plants. The results showed that the best type of growing media for the propagation of arbuscular mycorrhizal fungi was soil + husk with a ratio of 2:1, while the highest number of spores was obtained in soil growing media. Arbuscular mycorrhizal fungi reproduce better with the use of corn as a host plant than with sorghum. The use of soil + husk charcoal (2:1) planting media with corn as the host plant resulted in better host plant growth as indicated by the number of leaves and better root length.
Internationalisation of cataloguing in cultural institutions with RDA using the example of the German-speaking region
Authors: Behrens Renate
Published: June 2024

Many modern models and standards for cataloguing collections in cultural institutions have an international approach and aim to be applicable across different cultural sectors. A goal that at first glance seems unlikely and has not yet been fully realised. But what are the chances of such a concept being realised? How can the balancing act between internationalisation and local requirements be achieved? What do new technologies offer us and what experiences are currently being made in practice? This article aims to answer these questions and describe them using the example of the implementation of the new Official RDA Toolkit in German-speaking libraries.
