Effacements et fulgurances : autour de la mort dans Journal 1 de Jean-Luc Lagarce
Authors: Chevalier Élisabeth 
Published: November 2024

Le présent article se penche sur les modalités de la mort dans l’oeuvre cinématographique Journal 1, réalisée par Jean-Luc Lagarce (1957-1995) en 1992, alors qu’il était atteint du sida. Ces modalités reposent sur l’intermédialité de l’oeuvre, qui laisse une place prédominante au texte diaristique. Tout tournés vers le monde extérieur, le texte et l'image contribuent à l’effacement du sujet de son propre journal, laissant l’avant-plan de l’oeuvre vacant. En mobilisant la narratologie intermédiale par le biais de notions comme la focalisation, cet article vise à montrer comment la mort, sans être abordée de front ni à la première personne, prend forme dans cet espace. La mort apparaît dès lors comme un sujet collectif plutôt que comme une expérience individuelle.
The potential of the university teacher's Telegram channel for the development of the university's image
Authors: Afanas'eva Anastasiya Georgievna 
Published: November 2024

The subject of the study is the content of the Telegram channel of a university teacher as a means of forming the image of the university. The object of the study is the potential of the employee's Telegram channel as a contribution to the organization's public relations. The author examines this issue in detail using the example of higher education organizations, choosing large and small universities for practical analysis and comparing the content of Telegram channels of those teachers who advertise their affiliation to the university. Special attention is paid to two different approaches typical for large and small universities, respectively: in the first case, the professors positions themselves as professionals regardless of teaching activities, in the second – precisely as university employees. As a result of the analysis, recommendations have been developed that will allow universities to productively use the potential of new media. When selecting the research material, the method of continuous sampling of employees leading Telegram channels and the content of the Telegram channels themselves was used. The author used the method of content analysis of publications, analysis of the quantitative composition of the audience, as well as strategies for the interaction of the channel author with his audience through feedback tools. The main conclusions of the conducted research are, firstly, the statement of the fact of the extremely small use of the potential of employees' Telegram channels to build the image of the organization in the field of higher education. With great attention to the personality of the teacher and the significant influence of his personality on the views of students, tastes in the field of art and culture and the choice of a future profession, the professorship does not convert this influence into the space of new media. A special contribution of the author to the research of the topic is the identification of two strategies for the interaction of the personality of the author of the Telegram channel with his profession as a university teacher. Conditionally, they can be designated as the primacy of professional success and personal brand, regardless of teaching, and the primacy of teaching, regardless of personal brand. The novelty of the research lies in the research of the teacher's Telegram channel, undertaken for the first time in Russian science, precisely in connection with the image of the university: for example, there are studies of teachers' Telegram channels in their connection with the teaching process (assignment placement, dialogues with students through the Telegram platform), but the connection with the positioning of the university and its image has not been previously considered.

Published: November 2024

Drought is a key stress factor that limits rice production globally. The present study was carried out to identify drought tolerant rice lines at the germination and seedling stages using polyethylene glycol (PEG) induced stress. Twenty promising high yielding BC2F4 lines, stacked with drought yield QTLs qDTY₁⸳₁ and qDTY₁₂.₁, derived from the cross between Manu Ratna X Improved White Ponni, were subjected to drought stress. Drought was imposed during germination using three levels (0, 10 and 15%) of polyethylene glycol (PEG 6000) concentrations. The experiment was conducted in factorial completely randomized block design with three replications and the observations on number of seeds germinated, root length, shoot length, germination index, germination stress tolerance index, fresh weight stress tolerance index, dry weight stress tolerance index and seedling vigour index were evaluated after stress treatment. A significant difference was noted among lines for characters under drought stress. Among the lines, MIB-29-2-3-1, MIB-29-8-5-35, MIB-43-5-3-66 and MIB-119-5-7-33 were selected which showed higher germination percentage, root length, shoot length, germination stress tolerance index and and seeding vigour index. The selected lines can be further evaluated in the field to develop drought tolerant rice varieties.

Published: November 2024

Grain amaranth (Amaranthus spp.) is a highly versatile and nutrient-dense pseudo-cereal that has gained increasing importance in global food systems. Developing diverse varieties and hybrids of grain amaranth (Amaranthus spp.) is essential for harnessing its full potential as a climate-resilient and nutritionally rich crop. Germplasm studies provide a comprehensive understanding of the genetic diversity within amaranth, facilitating the breeding of improved cultivars that combine desirable traits such as higher yield, enhanced nutritional content, and increased tolerance to biotic and abiotic stresses. Varietal development and hybridization can optimize characteristics like seed size, growth habit, and adaptability, making amaranth more suitable for a range of agroecological zones. In this direction present study conducted by evaluating 180 grain amaranth germplasm accessions for yield and contributing factors during the summer 2024 at the ICAR-IISS Regional Station in Bengaluru adjacent to NSP. Genetic distances among 180-grain amaranth germplasm accessions were determined using K-means clustering, resulting in 06 distinct groupings. Cluster V comprised of more number of accessions (48) and the least number of accessions in cluster VI (15). As per PCA, eight eigen values explains the total variance; among which PC1 explained maximum variance 82.06% followed by PC2, PC3, PC4, PC5, PC6, PC7 and PC8 explained 8.87%, 5.39%, 1.63%, 1.02%, 0.51%, 0.45% and 0.07 % respectively.

Published: November 2024

One of the primary challenges in ragi cultivation is the reliance on traditional farming methods, which involve labor-intensive practices from land preparation to post-harvest operations. This not only increases production costs but also contributes to excessive drudgery. Labor shortages, especially during peak farming periods, further exacerbate the situation by driving up costs and reducing overall productivity. In this context, mechanization has become critical for ensuring timely agricultural operations, which are key to maximizing crop yields. The evaluation of tractor-operated seed drills has shown promising results, including a reduction in seed usage when compared to traditional methods. It is found that the effective field capacity and field efficiency is 0.77 ha/h and 92.7 per cent respectively. Cost of savings when compared to the broad casting is Rs. 239/ha. Moreover, the mechanization of ragi sowing has effectively eliminated the drudgery associated with manual sowing, making the process more efficient and cost-effective.

AbstractThe development of solution‐processed field effect transistors (FETs) based on organic and hybrid materials over the past two decades has demonstrated the incredible potential in these technologies. However, solution processed FETs generally require impracticably high voltages to switch on and off, which precludes their application in low‐power devices and prevent their integration with standard logic circuitry. Here, a universal and environmentally benign solution‐processing method for the preparation of Ta2O5, HfO2 and ZrO2 amorphous dielectric thin films is demonstrated. High mobility CdS FETs are fabricated on such high‐κ dielectric substrates entirely via solution‐processing. The highest mobility, 2.97 cm2 V−1 s−1 is achieved in the device with Ta2O5 dielectric with a low threshold voltage of 1.00 V, which is higher than the mobility of the reference CdS FET with SiO2 dielectric with an order of magnitude decrease in threshold voltage as well. Because these FETs can be operated at less than 5 V, they may potentially be integrated with existing logic and display circuitry without significant signal amplification. This report demonstrates high‐mobility FETs using solution‐processed Ta2O5 dielectrics with drastically reduced power consumption; ≈95% reduction compared to that of the device with a conventional SiO2 gate dielectric.

Published: May 2018

AbstractHybrid colloids consisting of noble metal cores and metal oxide shells have been under intense investigation for over two decades and have driven progress in diverse research lines including sensing, medicine, catalysis, and photovoltaics. Consequently, plasmonic core–shell particles have come to play a vital role in a plethora of applications. Here, an overview is provided of recent developments in the design and utilization of the most successful class of such hybrid materials, silica‐coated plasmonic metal nanoparticles. Besides summarizing common simple approaches to silica shell growth, special emphasis is put on advanced synthesis routes that either overcome typical limitations of classical methods, such as stability issues and undefined silica porosity, or grant access to particularly sophisticated nanostructures. Hereby, a description is given, how different types of silica can be used to provide noble metal particles with specific functionalities. Finally, applications of such nanocomposites in ultrasensitive analyte detection, theranostics, catalysts, and thin‐film solar cells are reviewed.
Interstitial Occupancy by Extrinsic Alkali Cations in Perovskites and Its Impact on Ion Migration

Published: May 2018

AbstractRecent success in achieving highly stable Rb‐containing organolead halide perovskites has indicated the possibility of incorporating small monovalent cations, which cannot fit in the lead‐halide cage with an appropriate tolerance factor, into the perovskite lattice while maintaining a pure stable “black” phase. In this study, through a combined experimental and theoretical investigation by density functional theory (DFT) calculations on the incorporation of extrinsic alkali cations (Rb+, K+, Na+, and Li+) in perovskite materials, the size‐dependent interstitial occupancy of these cations in the perovskite lattice is unambiguously revealed. Interestingly, DFT calculations predict the increased ion migration barriers in the lattice after the interstitial occupancy. To verify this prediction, ion migration behavior is characterized through hysteresis analysis of solar cells, electrical poling, temperature‐dependent conductivity, and time‐dependent photoluminescence measurements. The results collectively point to the suppression of ion migration after lattice interstitial occupancy by extrinsic alkali cations. The findings of this study provide new material design principles to manipulate the structural and ionic properties of multication perovskite materials.
Materials, Processes, and Facile Manufacturing for Bioresorbable Electronics: A Review
Authors: Yu Xiaowei , Shou Wan , Mahajan Bikram K. , Huang Xian , Pan Heng 
Published: May 2018

AbstractBioresorbable electronics refer to a new class of advanced electronics that can completely dissolve or disintegrate with environmentally and biologically benign byproducts in water and biofluids. They have provided a solution to the growing electronic waste problem with applications in temporary usage of electronics such as implantable devices and environmental sensors. Bioresorbable materials such as biodegradable polymers, dissolvable conductors, semiconductors, and dielectrics are extensively studied, enabling massive progress of bioresorbable electronic devices. Processing and patterning of these materials are predominantly relying on vacuum‐based fabrication methods so far. However, for the purpose of commercialization, nonvacuum, low‐cost, and facile manufacturing/printing approaches are the need of the hour. Bioresorbable electronic materials are generally more chemically reactive than conventional electronic materials, which require particular attention in developing the low‐cost manufacturing processes in ambient environment. This review focuses on material reactivity, ink availability, printability, and process compatibility for facile manufacturing of bioresorbable electronics.

AbstractA stereolithography‐based bioprinting platform for multimaterial fabrication of heterogeneous hydrogel constructs is presented. Dynamic patterning by a digital micromirror device, synchronized by a moving stage and a microfluidic device containing four on/off pneumatic valves, is used to create 3D constructs. The novel microfluidic device is capable of fast switching between different (cell‐loaded) hydrogel bioinks, to achieve layer‐by‐layer multimaterial bioprinting. Compared to conventional stereolithography‐based bioprinters, the system provides the unique advantage of multimaterial fabrication capability at high spatial resolution. To demonstrate the multimaterial capacity of this system, a variety of hydrogel constructs are generated, including those based on poly(ethylene glycol) diacrylate (PEGDA) and gelatin methacryloyl (GelMA). The biocompatibility of this system is validated by introducing cell‐laden GelMA into the microfluidic device and fabricating cellularized constructs. A pattern of a PEGDA frame and three different concentrations of GelMA, loaded with vascular endothelial growth factor, are further assessed for its neovascularization potential in a rat model. The proposed system provides a robust platform for bioprinting of high‐fidelity multimaterial microstructures on demand for applications in tissue engineering, regenerative medicine, and biosensing, which are otherwise not readily achievable at high speed with conventional stereolithographic biofabrication platforms.

One‐step Synthesis and Enhanced Thermoelectric Properties of Polymer–Quantum Dot Composite Films
Authors: Shi Wei , Qu Sanyin , Chen Hongyi , Chen Yanling , Yao Qin , Chen Lidong 
Published: May 2018

AbstractConventional syntheses of polymer–inorganic composite thermoelectric materials suffer major problems such as inhomogeneity, large particle size, and oxidation that result in ineffective loading. Now a one‐step synthesis can be used to fabricate high‐quality small‐sized anions codoped poly(3,4‐ethylenedioxythiophene):dodecylbenzenesulfonate/Cl‐tellurium (PEDOT:DBSA/Cl‐Te) composite films using a series of novel TeIV‐based oxidants. The synchronized production of PEDOT and Te results in thick and homogeneous films containing evenly distributed and well‐protected Te quantum dots. Owing to the heavily doped crystalline polymer matrix as well as the <5 nm unoxidized Te quantum dot loading, at low Te concentrations as 2.1–5.8 wt %, the films exhibits high power factors of about 100 μW m−1 K−2, which is 50 % higher compared to a pure PEDOT:DBSA film.

Authors: Shen Bin , Tatchen Jörg , Sanchez‐Garcia Elsa , Bettinger Holger F. 
Published: May 2018

AbstractUndecacene, the largest member of the acene family, was photogenerated in a polymer matrix under cryogenic conditions from a precursor with two α‐diketone bridges. The electronic absorption of undecacene extends into the NIR region, but the spectrum is dominated by two strong absorptions in the UV/Vis range. The HOMO–LUMO transition is continuously shifted to lower energies as the number of rings of the acene increases (E vs. 1/N, N=number of rings), which is in line with the strong electron correlation calculated by DFT/MRCI.
Acylstannanes: Cleavable and Highly Reactive Photoinitiators for Radical Photopolymerization at Wavelengths above 500 nm with Excellent Photobleaching Behavior

Published: May 2018

AbstractWithin this work, a novel acylstannane‐based photoinitiator (PI) is presented. Tetrakis(2,4,6‐trimethylbenzoyl)stannane (1) displays outstanding properties compared to state‐of‐the‐art acylgermane‐based initiators. Most importantly, the initiator shows absorption up to 550 nm, which allows higher penetration depths, especially in highly filled photopolymers. Besides that, 1 shows extremely high photoinitiating activity towards (meth)acrylic double bonds, as well as very fast photobleaching. Furthermore, unlike many organotin compounds, 1 shows surprisingly low cytotoxicity.
Manipulating Metal‐to‐Metal Charge Transfer for Materials with Switchable Functionality
Authors: Meng Yin‐Shan , Sato Osamu , Liu Tao 
Published: May 2018

AbstractMetal‐to‐metal charge transfer (MMCT) describes electron transfer between metal ions, to generate valence isomers with markedly different electronic configurations. In particular, MMCT changes the spin states of single‐metal sites and the coupling interactions between them, while also changing the symmetry in charge distribution. The result is a drastic change in both magnetic and electric properties of the affected material. Moreover, MMCT causes significant variation in bond length and absorption spectra, and induces unusual thermal expansion and photochromic behavior. Thus, materials demonstrating MMCT in response to external stimuli are excellent candidates for switchable multifunctional devices with synergistic responses. In this Minireview, recent progress in utilizing MMCT units as actuators to tune magnetic, electric, thermal expansion, and photochromic properties in cyanide‐bridged systems is highlighted, and emphasis is given to the remaining challenges and future perspectives in the field.
Composition and Phosphorous Profile of High‐Protein Rice Flour and Broken Rice, and Effects of Further Dry and Wet Processing
Authors: Liu Keshun 
Published: May 2018

AbstractHigh‐protein rice flour (HPRF), a coproduct of enzymatic processing for rice syrup production, and broken rice (feedstock) were collected from a commercial source and characterized for chemical composition and phosphorus (P) profile. The effects of dry fractionation, wet extraction/leaching, and particle size reduction on protein enrichment and phytate removal were also investigated. The HPRF contained 68.72, 7.54, 3.66, 8.27, and 11.56 (% dry matter) of protein, oil, ash, residual starch, and other carbohydrates, respectively, equivalent to 90% starch reduction and more than sevenfold increase in protein, oil, and ash over broken rice. Sieving or particle size reduction followed by sieving caused about 5% increase in the protein content. Protein extractability from HPRF was very low over a wide pH range regardless of sample particle sizes, indicating total protein denaturation by the commercial process, but leaching HPRF in an aqueous medium or aqueous ethanol enriched its protein by 10%. HPRF contained 4.41, 0.27, 3.00, and 7.68 (mg g−1 dry matter) of phytate P, inorganic P, rest of P and total P, respectively, representing 7.0‐, 2.7‐, 5.2‐, and 5.9‐fold increase, respectively, over the four types of P found in broken rice. High phytate P in HPRF raises environmental concerns, since excess P excretion into manures is expected when fed to animals. About 15% phytate could be removed by leaching HPRF in an aqueous medium having a mild acidic to mild alkaline pH, but not with aqueous alcohol.
