Features of Perception of Pre-revolutionary Non-fiction Films
Authors: Beliakov Viktor Konstantinovich
Published: September 2023

The purpose of this work is to reveal the peculiarities of perception of historical archival newsreels on the example of pre-revolutionary non-fiction films. The objective of the study is to identify the qualities of pre-revolutionary newsreels that influenced the mass audience before the revolution and compare them with those qualities that come out on top when perceived by modern viewers. In the work, an analytical approach is used as a method, which is based on theoretical provisions arising from the consideration of the specifics of newsreels as a special type of cinematography. The formation of Russian non-fiction cinema at an early stage is also considered, the techniques used in its development are revealed, and the extant evidence of the perception of newsreels in the first cinemas is studied. Films considered are : "The Sovereign Emperor, the Empress Empress and the Heir Tsarevich are pleased to taste sailor food on the imperial yacht "Standard" during their stay in the Skerries in 1908" (1908), "Asbestos mining in the Urals" (1911) and "The opening of the bridge across the Volga in the center of Rzhev" (1911). The results of the study confirm the influence of the so-called visual turn that occurred and indicate a fundamental difference in the perception of visual information compared to verbal. When analyzing the preserved film materials, including documentaries, it is noticeable that now these ephemeral screen images convey the breath of authentic life, and we look at the screen not to learn any story, but to feel the atmosphere of being of those people. The novelty of the undertaken research lies in the development of a model of perception of pre-revolutionary newsreels both in general terms and from the point of view of a specific audience before and now.

Published: September 2023

Introduction. The Allgöwer-Donati suture technique reportedly has lower incision perfusion impairment compared with other suture techniques. The authors of the present case series hypothesized that suture technique selection to achieve lower incision perfusion impairment may result in improved healing rates and decreased incidence of wound complications in partial foot amputations, specifically TMAs. Objective. To evaluate the efficacy of TMA with skin closure completed using the Allgöwer-Donati suture technique. Materials and Methods. The records of 7 patients (8 limbs) who underwent closure with the Allgöwer-Donati suture technique after TMA between March 2021 and March 2022 were retrospectively reviewed. Only patients with a diagnosis of gangrene were included. Results. Five of 8 limbs (62.5%) healed uneventfully, with an average time to healing of 3.3 weeks. Six of 8 limbs (75%) healed within 4 weeks, and 1 limb was lost to follow-up. Conclusions. The results of this small case series suggest that use of the Allgöwer-Donati suture technique may result in decreased incidence of wound complications by allowing improved perfusion at the amputation site.

Published: September 2023

Introduction. PAD frequently co-occurs with diabetes, often leading to chronic nonhealing wounds. Foot gangrene and amputation are common outcomes of untreated CLI. Case Report. A 67-year-old male with diabetes and deteriorating limb ischemia following surgical stress underwent successful surgical repair after emergency PTA of the SFA for extensive heel necrosis. After surgical debridement of necrotic heel tissue, the ABI on the affected side suddenly reduced to 0.36, but it improved to 1.06 at 4 weeks following stenting angioplasty, allowing the subsequent flap surgery to repair the heel defect. At the 1-year follow-up visit, the patient exhibited durable heel coverage and the restoration of weightbearing function. No signs or symptoms indicative of restenosis were evident in the blood vessel treated with stent angioplasty. Conclusion. This case highlights the importance of proper evaluation of critical ischemic conditions and the need for prompt endovascular interventions in preserving the at-risk diabetic foot.
Light-driven membrane assembly, shape-shifting, and tissue formation in chemically responsive synthetic cells
Authors: Lee Youngjun , Fracassi Alessandro , Devaraj Neal K.
Published: September 2023

Living systems create remarkable complexity from a limited repertoire of biological building blocks by controlling assembly dynamics at the molecular, cellular, and multicellular level. An open question is whether simplified synthetic cells can gain similar complex functionality by being driven away from equilibrium. Here we describe a dynamic synthetic cell system assembled using artificial lipids responsive to both light and chemical stimuli. Irradiation of disordered aggregates of lipids leads to the spontaneous emergence of giant cell-like vesicles, which revert to aggregates when illumination is turned off. Under irradiation, the synthetic cell membranes can interact with chemical building blocks, remodeling their composition and forming new structures that prevent the membranes from undergoing retrograde aggregation processes. The remodeled light-responsive synthetic cells reversibly alter their shape under irradiation, transitioning from spheres to rod-like shapes, mimicking energy dependent functions normally restricted to living materials. In the presence of non-covalently interacting multivalent polymers, light-driven shape changes can be used to trigger vesicle crosslinking, leading to the formation of functional synthetic tissues. By controlling light and chemical inputs, the stepwise one-pot transformation of lipid aggregates to multivesicular synthetic tissues is feasible. Our results suggest rationale for why even early protocells may have required and evolved simple mechanisms to harness environmental energy sources to coordinate hierarchical assembly processes.

Published: September 2023

Understanding defect healing is necessary to predict the response of devices based on nanoparticle-superlattices with controlled electronic and optoelectronic performance. Key questions remain regarding the process of nanoparticle (NP) interactions and resulting assembly dynamics and defect self-elimination. In particular, for anisotropic particles, additional degrees of freedom beyond those of spherical particles, associated with rotational dynamics and torques, significantly impact phenomena. Here we investigate nanocube (NC) superlattices by employing liquid phase transmission electron microscopy, continuum theories, and molecular dynamics (MD) simulations. Analyzing interparticle forces and torques due to van der Waals, Brownian, and ligand interactions, we find that the latter dominates and the anisotropic NC morphology introduces significant torques. In inhomogeneous regions, unbalanced forces and torques induce NC translations and rotations that are transmitted to neighboring NCs, prompting “chain interactions” in a two-dimensional (2D) network, leading to defect self-elimination. The development of this fundamental understanding will further enable design and fabrication of defect-free superlattices, as well as those with tailored defects via assembly of anisotropic particles.

Published: September 2023

The iron-catalyzed asymmetric oxidative coupling is a challenging transformation that is typically restricted to naphthol substrates (Csp2–H) with carefully designed chiral ligands. Herein, we established a mechanochemical protocol for iron-catalyzed asymmetric Csp3–H/ Csp3–H coupling between glycines and β-ketoesters. By using size-tunable liquid additives via non-covalent bond interaction with simply designed chiral salen ligands and substrates under mechanochemical treatment, it is possible to improve the asymmetric induction and offer a variety of structurally diverse α-amino acid derivatives in high enantiopurity. Mechanistic study revealed that the iminium ion derived from acid assisted aerobic oxidation of glycine ester was the key intermediate of the reaction, and the liquid additive t-BuOH act both as a stabilizer for the iminium ion via N–H···O interaction and as an assistant for enantio-control. Moreover, a safer, cleaner, and more energy-conservation route via mechanochemical accelerated aging was first disclosed for this asymmetric Csp3–H/ Csp3–H coupling reaction.

Published: September 2023

Selective acylation of the N-terminus over side-chains in peptides and proteins is a highly desirable but challenging reaction in chemical biology. Here we report a biomimetic approach using enzymatic in situ activation of carboxylic acids with ATP to generate reactive acyl-adenosine phosphates, which display high selectivity for the N-termini of peptides and proteins, including pharmaceutically relevant liraglutide, insulin and glucagon. The acylation tolerates a range of unsubstituted and substituted fatty acids including di-acids, thus making it suitable for N-terminal biorthogonal labelling strategies.

Acquiring spatial control of nanoscopic metal clusters is central to their function as efficient multi-electron catalysts. However, dispersing metal clusters on surfaces or in porous hosts is accompanied by an intrinsic heterogeneity that hampers detailed understanding of the chemical structure and its relation to reactivities. Tethering pre-assembled molecular metal clusters into polymeric, crystalline 2D or 3D networks constitutes an unproven approach to realizing ordered arrays of chemically well-defined metal clusters. Herein, we report the facile synthesis of a {Pd3} cluster-based organometallic framework from a molecular triangulo-Pd3(CNXyl)6 (Xyl = xylyl; Pd3) cluster under chemically mild conditions. The formally zero-valent Pd3 cluster readily engages in a complete ligand exchange when exposed to a chemically similar, ditopic isocyanide ligand, resulting in the spontaneous polymerization into a 2D coordination network (Pd3-MOF). The structure of Pd3-MOF could be unambiguously determined by continuous rotation 3D electron diffraction (3D-ED) experiments to an overall resolution of ~1.0 Å (>99% completeness), showcasing the applicability of 3D-ED to nanocrystalline, organometallic polymers. Importantly, the realization of Pd3-MOF paves the way for the exploitation of metal clusters as building blocks for rigidly interlocked metal nanoparticles at the molecular limit.
DiffSeqMol: A Non-Autoregressive Diffusion-Based Approach for Molecular Sequence Generation and Optimization
Authors: chen yangyang , Wang Zixu , Ye Xiucai
Published: September 2023

The application of deep generative models for molecular discovery has witnessed a significant surge in recent years. Currently, the field of molecular generation and molecular optimization is predominantly governed by autoregressive models regardless of how molecular data is represented. However, an emerging paradigm in the generation domain is diffusion models, which treat data non-autoregressively and has achieved significant breakthroughs in areas such as image generation. The potential and capability of diffusion models in molecular generation and optimization tasks remain largely unexplored. In order to investigate the potential applicability of diffusion models in the domain of molecular exploration, we proposed DiffSeqMol, a molecular sequence generation model, underpinned by diffusion process. DiffSeqMol distinguishes itself from traditional autoregressive methods by its capacity to draw samples from random noise and direct generating the entire molecule. Through experiment evaluations, we demonstrated that DiffSeqMol can achieve, even surpass, the performance of established state-of-the-art models on unconditional generation tasks and molecular optimization tasks.

Published: September 2023

The continuous rise of antimicrobial resistance is a serious threat to human health and already causing hundreds of thousands of deaths each year. While natural products and synthetic organic small molecules have provided the majority of our current antibiotic arsenal, they are falling short in providing new drugs with novel modes of action able to treat multidrug resistant bacteria. Metal complexes have recently shown promising results as antimicrobial agents, but the number of studied compounds is still vanishingly small, making it difficult to identify promising compound classes or elucidate structure-activity relationships. To accelerate the pace of discovery we have applied a combinatorial chemistry approach to the synthesis of metalloantibiotics. Utilizing robust Schiff-base chemistry and combining 7 picolinaldehydes with 10 aniline derivatives, and 5 axial ligands we have prepared a library of 420 novel manganese tricarbonyl complexes. All compounds were evaluated for their antibacterial properties and 10 lead compounds were identified, re-synthesized and fully characterized. All 10 compounds showed high and broad activity against Gram-positive bacteria. The best manganese complex displayed low toxicity against human cells with a therapeutic index of >100. In initial mode of action studies, we show that it targets the bacterial membrane without inducing pore formation or depolarisation. Instead, it releases its carbon monoxide ligands around the membrane and inhibits the bacterial respiratory chain. This work demonstrates that large numbers of metal complexes can be accessed through combinatorial synthesis and evaluated for their antibacterial potential, allowing for the rapid identification of promising metalloantibiotic lead compounds.

Published: September 2023

A computational design of linearly extended multiple resonance (MR)-type BN molecules based on DABNA-1 is proposed herein in the quest to find potential candidates that exhibit a negative singlet-triplet gap (ΔEST) and a large oscillator strength. The impact of a proper account of electron correlation in the lowest singlet and triplet excited states is systematically investigated by using double-hybrid functionals within the TD-DFT framework as well as wavefunction-based methods (EOM-CCSD and SCS-CC2) since this contribution plays an essential role in driving the magnitude of the ΔEST in MR-TADF and inverted singlet-triplet gap. Our results point out to a gradual reduction of the ΔEST gap with respect to the increasing sum of the number of B and N atoms, reaching negative ΔEST values for some molecules as a function of their size. The double hybrid functionals reproduce the gap with only slight deviation compared to available experimental data for DABNA-1, ν-DABNA, and mDBCz and nicely agree with high-level quantum mechanical methods (e.g., EOM-CCSD and SCS-CC2). Larger oscillator strengths are found compared to the azaphenalene-type molecules also exhibiting the inversion of their singlet and triplet excited states. We hope this study can serve as a motivation for further design of the molecules showing negative ΔEST based on boron and nitrogen doped polyaromatic hydrocarbons.

Published: September 2023

This paper centres on examining the link between emotional labour and dinning duration within the restaurant industry. In this study emotional labour practice was modelled as one of the crucial predictors of dining duration. This study adopted a multiple case study using a cross sectional design approach. The target population was 480 dyads encounters in 6 of the most popular fast food restaurant chains in Harare. Some 214 seat-in customers were the unit of analysis while wait staff were the unit of observation. In terms of responses, 200 responses were attained and were deemed sufficient for meaningful Structural Equation Modelling. The quantitative approach employed a self-completed structured questionnaire in collecting data. A structural equation modelling was run to test the direct effects, a multi-group structural equation modelling was run to test the moderating effects of categorical variables, and a moderated multiple regression was run to test the moderation effects of the latent variables. The study revealed various factors that influence the connection between emotional labour and dinning duration such as the gender factor of the people involved, the rate and strength of the interaction between restaurant employees and the clients. The outcome directed that emotional labour is positively associated with consumer dining duration. The consumer dining duration is in turn associated with consumer expenditures within the restaurant. However, all the hypothesised moderators had no statistically significant effect. The study recommended the use of emotional labour as one of the predictors for increased revenue in the restaurant industry through increased consumer spending as mediated by the dining duration under the scenario of excess capacity and limited demand.

TVET Lecturer Work-Integrated Learning: Opportunities and Challenges
Authors: Mesuwini Joseph , Mokoena Sello P
Published: September 2023

There is a widening gap between industry expectations and what Technical and Vocational Education and Training (TVET) lecturers teach to students. In South Africa, work-integrated learning (WIL) equips lecturers with industry skills and experience necessary for effective teaching and learning. Most TVET lecturers in South Africa lack industry experience. There is a lacuna of research as lecturers’ industry opportunities and challenges are not much researched. This study aims to explore the opportunities gained by lecturers through WIL and reflect on the challenges encountered in industry. The qualitative study adopted an interpretive paradigm and employed face-to-face semi-structured interviews to generate data from twenty-seven participants (18 lecturers and 9 industry personnel) in KwaZulu-Natal province, South Africa. Purposive sampling focused on characteristics of the lecturer population of interest, which was considered information-rich to answer the research questions. Mechanical industry personnel hosted lecturers and were considered information-rich. This study employed Kolb’s experiential learning theory, which was complemented by Shulman’s framework on domains of teacher knowledge. Data were analysed thematically from transcriptions, identifying patterns, coding, developing themes, juxtaposing the relationships amongst the different themes, and developing an interpretation of meaning. Findings revealed that lecturers acquired industry experience through exposure to the latest machines, technology processes and practices, and networking with artisans. Challenges included a lack of supervision and support from industry personnel and college, a lack of hands-on engagement with expensive machinery and weak industry induction processes. This study recommends an embedded WIL component in the training of TVET lecturers to ensure their competency. Some crucial issues are highlighted in this study which can improve TVET delivery and the livelihood of citizens.

Currently, most training programmes have shifted from the traditional methods of teaching to integrate technology; hence, the strategies for training using these technologies are required. In this study, 20 lecturers from three TVET college campuses were interviewed and their teachings were observed. The ultimate purpose of this qualitative study was to propose innovative strategies for integrating technologies into the agricultural programmes. The research participants who were regarded as being knowledgeable and experienced in agricultural programmes were selected using the purposive and convenient sampling method. Data was thematically analysed and presented using categories such as the exploration of technology integration; the experimentation with technology integration; the adoption of technology integration; and the advanced technology integration that was adopted from the Kotrlik-Redmann (2003) framework. The findings suggest that the innovative strategies, including but not limited to being proactive, improvising, being developmental, and seeking assistance strategies can be used to integrate technologies. The study reveals that the lecturers use various innovative strategies for integrating technologies into the agricultural programmes. We recommend that the TVET colleges offering agricultural programmes, the Department of Higher Education and Training, and the other key stakeholders implement innovative strategies to help in the complete integration of technology. We also suggest the need to provide TVET lecturers with continuous training in the use of innovative technology.

This sociopragmatics study aims to investigate the various types of directive speech acts and the markers of local wisdom in the communication of elementary students in  Kolaka. The research design employed is qualitative descriptive, chosen for its ability to describe the types of directive speech acts and the manifestation of local wisdom within the context of elementary school students. The participants in this study consisted of elementary school students from Kolaka Regency. Data were collected through non-participant observation, and the analysis followed qualitative data procedures based on the interactive model developed by Miles and Huberman, which involved data reduction, data presentation, and drawing conclusions. The findings revealed four types of directive speech acts commonly used by elementary school students: demanding, commanding, begging, and challenging. These directive speech acts were found to be influenced by the cultural context, specifically manifested through the use of clitics. The clitics -ko, -mi, -ka, -hae, and -na were identified as significant markers of the local wisdom in the communication of elementary students, observed in utterances such as lihatko, ayomi, pindahko, biarmi, siniko, and jemputna. These clitics not only serve as markers of cultural identity but also indicate different levels of politeness in communication.  Further implications for language teaching practices are also discussed.

Rehabilitasyon, motor yeteneklerini kısmen ya da tamamen kaybeden kişilerin, kayıp fonksiyonlarını geri kazanmalarını sağlamlarına yardımcı olan bir terapi sürecidir. Terapi sürecinde tekrarlanan hareketlerin doğruluğu ve sürekliliği rehabilitasyon sürecinin başarısı açısından önem taşımaktadır. Bu nedenle, rehabilitasyon sürecinin devamlılığını sağlayabilmek adına, egzersizlerin rehabilitasyon merkezlerine gitmeksizin devam ettirilebileceği sistemlerin geliştirilmesi gerekmektedir. Bu çalışmada, el rehabilitasyonu uygulamalarına yönelik, el ve parmak hareketlerini taklit eden bir robot el uygulaması geliştirilmiştir. El hareketlerini algılamak için IMU sensör, parmak hareketini algılamak için ise, bir esneklik sensörü kullanılmıştır. El hareketleri ile robot el üzerindeki iki motoru kontrol edilmesi; esneklik sensörü ile ise, robot üzerindeki kıskacın kontrol edilmesi ve robot ele kavrama hareketinin yaptırılması sağlanmaktadır. Katılımcılara, robot eli kullanarak silindirik bir nesneyi hedef noktaya taşıma görevi verilerek, görev tamamlama süreleri kaydedilmiştir.
