Trapping proteins on nanopores by dielectrophoresis
Authors: Colburn Taylor , Matyushov Dmitry
Published: February 2023

Interest in the phenomenon of dielectrophoresis has gained significant attention in recent years due to its potential for sorting, manipulation, and trapping of solutes, such as proteins, in aqueous solutions. For many decades protein dielectropheresis was considered impossible, as the predicted magnitude of the force arising from experimentally accessible field strengths could not out-compete thermal energy. This conclusion was drawn from the mainstay Clausius-Mossotti (CM) susceptibility applied to the dielectrophoretic force. However, dielectric interfacial polarization leading to the CM result does not account for a large protein dipole moment which is responsible for the dipolar mechanism of dielectrophoresis outcompeting the CM induction mechanism by three-four orders of magnitude in the case of proteins. Here we propose an explicit geometry within which the dipolar susceptibility may be put to the test. The electric field and dielectrophoretic force are explicitly calculated, and the dependence of the trapping distance on the strength of the applied field is explored. A number of observable distinctions between the dipolar and induction mechanisms are identified.
Concealed antiaromaticity
Authors: Glöcklhofer Florian
Published: January 2023

Numerous articles in the recent literature report molecules that are claimed to be antiaromatic, as they feature a formal 4n π-electron system. The purported antiaromaticity often serves well as an explanation for some of the observed properties, but it neglects the actual local aromaticity of the molecules, which often feature multiple subunits with 4n+2 π-electrons besides the formal 4n π-electron system. This has led to considerable criticism from those who believe that the term antiaromatic should not be used for any molecule with a formal 4n π-electron system but should be reserved for truly antiaromatic molecules. To reconcile the different viewpoints, the term and concept of concealed antiaromaticity is introduced here. The concept accepts that many of the molecules claimed to be antiaromatic are not truly antiaromatic. However, it acknowledges that this does not prevent those molecules from exhibiting behaviour under certain conditions that would normally be expected for antiaromatic molecules, due to the formal, concealed 4n π-electron system that characterizes these molecules. Based on the conditions under which the molecules can behave like antiaromatic molecules, three types of concealed antiaromaticity are distinguished here: concealed antiaromaticity revealable in redox reactions (Type I-CA), upon excitation (Type II-CA), and in intermolecular interactions (Type III-CA). The concept of concealed antiaromaticity will enable the conscious, rational design of molecules that show the desirable properties of antiaromatic molecules while avoiding or diminishing the undesirable properties, namely the low stability of truly antiaromatic molecules. This will yield molecules and materials with highly interesting properties for a broad range of applications, from organic electronics to supramolecular chemistry.

Published: February 2023

All-solid-state Li-metal batteries (ASLMBs) have the potential to outperform conventional Li-ion batteries in terms of high energy density and safety; however, their applications are challenged by the dendrite-related short circuit. Therefore, it is imperative to understand the mechano-electro-chemo behavior of Li. For the first time, we nondestructively visualize the Li behavior in ASLMBs through operando neutron imaging and X-ray computed tomography (XCT). The 2D neutron radiography tracks the real-time Li evolutions before and after the "soft short". The 3D neutron tomography evidences the Li-metal deformation, and XCT provides 3D views of the battery after the "soft short". Despite "soft short", our observation indicates that Faradaic processes persist. Meanwhile, the coupling of stacking pressure and plating-induced stress triggers the Li-metal deformation toward the current collector and the SE, which results in the "soft short". This work inspires future research on stabilizing the Li metal in ASLMBs from the mechano-electro-chemo aspect.

The electrochemical generation of molecular complexity via CH bond transformations without pre-functionalization of molecules, stoichiometric amounts of oxidizing/reducing species or precious metal catalysts, represent a highly sustainable technology and green methodology of contributing toward resource economy. Thus, renewable electricity provides clean electron (oxidant/reductant) that initiate a reaction cascade via producing reactive intermediates that facilitate in the building of new bonds for valuable chemical transformations. The application of modern enabling strategies (electrochemistry, photochemistry & microfluidics) in organic transformations will accelerate the process to achieve sustainable CH bond activation and to access valuable chemicals, pharmaceuticals, and fine chemicals under safe & environmentally friendly conditions. Herein, we discussed enabling tools and technologies used for the recent CH bonds functionalization of Arenes / (Hetero)Arenes.

Published: January 2023

Ascorbic acid (H2A) is a well-known antioxidant to protect cellular components from free radical damage, meanwhile it is also emerged as pro-oxidant in cancer therapy. However, such contradictory mechanisms underlying H2A oxidation are not well understood. Here, we report the discovery of Fe leaching during catalytic H2A oxidation using Fe-N-C nanozyme as a ferritin mimic and its influence in selectivity of oxygen reduction reaction (ORR). Owing to the heterogeneity, Fe-Nx sites in Fe-N-C primarily catalyzed the H2A oxidation and 4e ORR via an iron-oxo intermediate; meanwhile marginal N-C sites catalyzed the 2e ORR via an O2 intermediate with H2O2 production, although which was less favorable in kinetics and hardly observable in the early stage. Nonetheless, trace O2 accumulated and attacked Fe-Nx sites, leading to a linear leakage of unstable Fe ions up to 420 ppb when the concentration of H2A increased. As a result, a substantial fraction (~40%) of N-C sites on Fe-N-C were activated, and a new path for Fenton-type H2A oxidation was finally enabled. After Fe ions diffused into the bulk solution, the ORR at the N-C sites stopped at H2O2 production, which was the origin for the pro-oxidant effect by H2A. This work highlights the Fe-leakage occurring on Fe-N-C nanozymes and uncovers the multifaceted insights of ORR selectivity in H2A oxidation under realistic conditions.

Carataca y Damanaca: dos zorros indios del siglo XIX
Authors: Rodríguez García Miguel
Published: February 2023

Aunque la presencia de la cuentística oriental en la literatura española disminuye a finales de la Edad Media, hemos encontrado un testimonio de su vitalidad en pleno siglo XIX: se trata de una versión del Panchatantra publicada en Instrucción para la mujer (1882-1883) y basada en una traducción francesa de Jean-Antoine Dubois (1826). En este trabajo llevamos a cabo un análisis de su historia marco y de sus fábulas, comparándolas con el texto en francés, con la traducción del Panchatantra de Alemany Bolufer y con otras versiones de los cuentos. Dedicamos especial atención al estudio de sus protagonistas, los zorros, que a lo largo de nuestra historia literaria han sustituido a los chacales indios, y aducimos los orígenes y algunos de los motivos de este cambio.
Life history of wahoo, Acanthocybium solandri, in the Tropical Eastern Atlantic Ocean – the importance of applying a suite of methods for fisheries assessment in data-limited situations
Authors: Kindong Richard , Wu Feng , Sarr Ousmane , Dai Libin , Tian Siquan , Dai Xiaojie
Published: January 2023

Unassessed  fisheries,  mostly  non-targeted  fisheries,  are  now particularly predominant in many commercial fisheries and are critical to food security in developing countries. These fisheries  typically  lack  reliable  data  essential  for  assessing  their  stocks,  leaving  them  susceptible  to  overfishing  and  declining  yield  over  time.  This  study  proposes  a  framework  for  determining  the  life  history  and  management  of  such  fisheries. Data on the length composition and reproduction of   wahoo   Acanthocybium   solandri,   a   common   bycatch   species    in    commercial    fisheries,    were    obtained    from    observers  aboard  Chinese  longline  vessels  in  the  Eastern  Atlantic  between  2010  and  2020  and  were  used  as  a  case  study.   A   comprehensive   methodological   approach   was   applied using data on this species to estimate its life history parameters,  to  evaluate  biological  reference  points,  and  to  provide  proxies  for  the  stock  status.  The  final  main  growth  parameters  obtained  were:  Linf  =  161.21  cm  FL  (157.34–194.68), K =  0.47/year  (0.14–0.65);  estimated  size  at  first  maturity was 89.6 cm FL. As assessed by the set of methods applied,  the  wahoo  stock  state  was  healthy  in  the  Tropical  Eastern  Atlantic  Ocean.  This  study  advises  against  using  a  single  approach  to  determining  life  history  parameters  in  data-limited fisheries, as this may affect reference points and thus management recommendations. This study provides a route whereby many easy-to-apply methods can be used to understand the status of multiple stocks in poorly managed fisheries, and thus provide management plans.

Comparative analysis of kinetic typography elements in movie title sequence
Authors: Luthfiasari Annisa , Fadillah Citra
Published: January 2023

Typography, usually closely related to printed media, has now been explored in digital media. These changes make typography, which is usually static, more dynamic. One example of digital typography is kinetic typography. Typography's position as a medium of visual and textual communication becomes more interesting because the element of motion in kinetic typography adds another meaning value. This study examines how typography reveals meaning in time-based media formats. In this study, three movie title sequences with different genres will be analyzed: Monsters Inc., Se7en, and Mission: Impossible — Ghost Protocol. The film was chosen because it has a dominant kinetic typography structure and has a good reputation in terms of visuals. The method of analysis is carried out by comparing the structure of the three title sequences based on the kinetic typography theory by Bellantoni and Woolman. Furthermore, an analysis of the semantic value of each title sequence was also carried out. This research is aimed to figure out the elements used in the visual creation of a title sequence and how these elements can construct meaning. From the analysis process it is known that each genre of the title sequence has different element variations which of course have their own meaning. The results of this study are expected to provide recommendations for the title sequence design method based on the genre like comedy animation, thriller, and action.
WORDS AND MEANINGS AT THE CROSSROADS OF MENTAL SPACES OF LANGUAGE AND CULTURE
Authors:   Russian State University for the Humanities, Zabotkina Vera I. , Boyarskaya Elena L. ,   Immanuel Kant Baltic Federal University
Published: January 2023

The article deals with the interaction between the conceptual spaces of language and culture within the framework of the language – culture – cognition triad. We argue that this interaction is based on a dynamic network of conceptual mappings. We prove that language and culture are connected by conceptual mappings within several dimensions: semiotic, communicative and cognitive. The main emphasis is on the analysis of the conceptual interactions between the mental spaces of two cultures and languages at several levels: at the macro level (the level of conceptual worldviews of two national cultures), at the meso level (the level of individual concepts) and at the micro level (the level of individual conceptual features that form the concept). We focus on the analysis of the micro level and prove the importance of conceptual features that have the highest degree of centrality, stability and high inferential potential in the process of conceptual mapping. Our study also proves that the inferential potentials of conceptual features do not coincide in two cultures and languages. This is reflected in the translation process. When translating features with a low inferential potential, the translator needs more cognitive efforts, since this process requires compensatory translation solutions to create the translation text. The maximum cognitive load on the translator should result in the minimization of the cognitive load on the recipient.
POSSIBILITY AND PROBABILITY JUDGMENTS IN DIFFERENT CULTURES
Authors:   Russian Academy of Sciences Institute of Linguistics, Demyankov Valery Z.
Published: January 2023

Ways of presenting opinions depend on mental cultures which include i.a. styles of forming judgments on possibility and on probability of events and of states of affairs. Research on a large multilingual corpus of texts in several West-European languages and in Russian shows that the possibility statements are used more than twice as often as the probability statements. The term ‘possibility’ in Latin and in modern languages denotes a physicalist attitude towards states of affairs. This term was coined much later than the term ‘probability’, originally connected to the human aspects of evaluation. The term ‘probabilis’ itself in Latin was a cognate of ‘probare’, which meant ‘approving’ and/or ‘controlling’ events. Additionally, in modern Romance languages, judgments of doubt and hope, i. e. sentences conveying speaker’s distancing from alien and non-actual opinions, usually contain verbs in a special ‘conjunctive mood’. Creating alternative ‘possible worlds’ as a figure of speech for ‘conjecture’ originated and was extensively used in writings by Leibniz in French, who used this figure in accordance with French grammar. The same ideas formulated in Russian or in German lack the ‘subjunctive’ mood, whereas it is obligatory in French.

Published: February 2023

Universities play a crucial role in promoting sustainable agriculture and community food security. One indicator of a successful education system is the measurement of the quality of the education's output, such as the transfer of information, technology, and agricultural innovations to increase the agricultural productivity of a society and ensure its food security. Even if university students obtained the same information and abilities in lectures, many female students do not work after graduation because they marry and would rather care for their families than implement the knowledge they gained. They have a career in agriculture, but it is not their primary occupation since they support their family. Women as farmers have a substantial and vital impact on household food security. Women have a crucial part in attempts to supply food for the home.

Published: February 2023

Finding suitable water sources for fish and plant cultivation appears to be difficult. In addition, land scarcity is decreasing agricultural productivity, so it is crucial to combine land and water conservation technology with various vegetable varieties for optimal yields. Aquaponics is a sustainable farming method that combines aquaculture and hydroponics. This water system must regularly circulate through the growing medium to provide the plants with nutrient-rich, filtered water.  This research develops a smart aquaponics system that uses a mobile application accessible via the internet to control and monitor acidity, water level, water temperature, and fish nutrition.  In this system, sensors are installed to collect data, which is then sent to the Ubuntu IoT Cloud server, which can be accessed in real time over the internet. So as to preserve the purity and circulation of water. In this study, the waterlevel sensor has a 100% measurement success rate, the pH sensor has a 93 % measurement success rate, and the temperature sensor has a 96% measurement success rate. The temperature and pH range of the pond water are optimal for aquaponics at 25 to 35 degrees Celsius and 6,5 to 7,5, respectively, and the aquaponics monitoring system is functioning properly. A suggestion for future research is the development of an aquaponic system that can be modified based on the type of plant and its nutritional requirements.

EUROPEAN UNION GLOBAL STRATEGY AND TURKEY: AN ANALYSIS OF THE TERM 2016-2021
Authors: Ünalp Çepel Zühal
Published: January 2023

The European Union (EU) has set a goal to be a global power in 2003 with the announcement of European Security Strategy. Nevertheless, this goal was stressed more decisively and obviously within the 2016 EU Global Strategy. The comparison between these strategies illustrates the change in rhetoric and foreign policy of the EU. With the 2016 Strategy, the EU has initiated to shape its own geopolitics, this time free from the US leadership, considering the migration crisis and especially the recently security threats over Europe.

This paper aims to concentrate on the status of Turkey in EU foreign policy and elaborate the reasons for the rise of EU’s focus on Turkey in its foreign policy in the term between 2016 and 2021. The paper argues that the emphasis made on the role of Turkey has been limited by the EU to several areas such as migration, counterterrorism and energy. Therefore, it is argued that the EU’s approach damages the cooperative understanding between the parties especially within the scope of the candidacy process.

Küreselleşme olgusuyla birlikte artış trendi gösteren dünya ticaretinin en önemli aktörlerinden birisi deniz ticaretidir. Ancak deniz taşımacılığı ve dolayısıyla gemilerin ticari birer öğe olarak kullanım düzeyinin artması çeşitli sorunları da beraberinde getirmektedir. Bu problemlerin başında çevre ve hava kirliliği gelmektedir. Özellikle küresel ısınma dolayısıyla dünyanın büyük riskler altında olduğu düşünüldüğünde dünyayı etkileyen her türlü kirliliğin önlenmesi için gereken tedbirlerin alınmasının gerekliliği bilinen bir gerçektir. Bu amaçla çeşitli otoriteler tarafından değerlendirmeler yapılmakta, raporlar yayınlanmakta ve kirliliği önlemeye yönelik tavsiye kararları aracılığı ile çeşitli uygulamalar hayata geçirilmektedir. Bu kapsamda değerlendirilen önemli uygulamaların başında The European Green Deal olarak bilinen Avrupa Yeşil Mutabakatı gelmektedir. Özellikle Avrupa Birliği’nin sürdürülebilir ekonomik tedbirleri almaya yönelik olarak ortaya koyduğu bu plan, dünyayı tehdit eden çevresel ve iklimsel problemlere çözüm yaratmayı hedeflemektedir. Bu çalışmada öncelikle Avrupa Yeşil Mutabakatına ilişkin literatüre yer verilmiş ve deniz taşımacılığından kaynaklanan karbon emisyonuna ilişkin kirlilik verileri kullanılarak denizcilik kökenli hava kirliliğinin etkileri değerlendirilmiştir. Mevcut verilerden yola çıkılarak deniz taşımacılığının kirliliğe ilişkin tedbirlere uyumu dikkate alınmış ve geleceğe yönelik öneriler sunularak çalışma sonuçlandırılmıştır.

The increase in the amount of fly ash and bottom ash waste every year requires proper management and utilization. In the manufacture of concrete, the use of fly ash and bottom ash can be used as a substitute material. However, it has not been utilized in making species in construction. This is because the exact proportion has not been obtained. The purpose of this study was to determine the correct proportions in the mortar with a mixture of fly ash and bottom ash. The research was carried out using experimental methods in the laboratory with cube-shaped specimens (5 x 5 x 5 cm) with 2 kinds of ratios between binder and fine aggregate, namely 1:2 and 1:4, each having a different percentage of sand and bottom ash, starting from from 20% to 80%. While the fly ash used is 10%. Tests carried out included material tests (Metal Oxidation Concentration Test and Sieve Analysis), and compressive strength tests (14 and 28 days). The results showed that the highest mortar compressive strength was at a ratio of 1:2 with fly ash as a cement mixture of 10% and bottom ash as a sand mixture of 20% with a compressive strength value of 16.8 MPa at the age of the specimen 28 days. The compressive strength value is in accordance with the provisions of SNI 03-6825-2002. The results of this study can be used by the community in making plaster work and can reduce the amount of waste that exists today.

Virtual reality (VR) is developing in line with the establishment of the learning metaverse, although the relationship between its acceptance and technological pedagogical content knowledge (TPACK) is very unclear. Therefore, this study aims to determine the effects of facility condition (FC), technological acceptance model (TAM), and TPACK on pre-service teachers’ use of VR in Indonesian science education courses. This condition emphasizes the description of these teachers’ readiness in designing VR for learning and teaching integration. The survey was conducted using 406 preservice teachers from 12 Indonesian universities, with confirmatory factor analysis (CFA) and partial least square-structural equation model (PLS-SEM) subsequently utilized. The results showed that PU (perceived usefulness), PEOU (perceived ease of use), behavior Intention (BI), TPACK, and FC were significantly and positively related. However, two hypotheses emphasizing the relationship between FC and TPACK to PEOU were rejected. These results are expected to facilitate preservice teachers in easily adopting VR learning in courses.
