Published: May 2021

Abstract. Vietnam is a major rice producer, and much of the rice grown is concentrated in the Red River Delta (RRD) and the Mekong River Delta (MRD). While the two deltas are highly productive regions, they are vulnerable to natural hazards and the effects of human-induced environmental change. To show that the processes and issues affecting food security are reinforcing, interdependent and operating at multiple scales, we used a systems-thinking approach to represent the major linkages between anthropogenic land-use and natural hazards and elaborate on how the drivers and environmental processes interact and influence rice growing area, rice yield and rice quality in the two deltas. On a local scale, demand for aquaculture and alternative crops, urban expansion, dike development, sand mining and groundwater extraction decrease rice production in the two deltas. Regionally, upstream dam construction impacts rice production in the two deltas despite being distally situated. Separately, the localized natural hazards that have adversely affected rice production include droughts, floods and typhoons. Outbreaks of pests and diseases are also common. Climate-change-induced sea level rise is a global phenomenon that will affect agricultural productivity. Notably, anthropogenic developments meant to improve agricultural productivity or increase economic growth can create many unwanted environmental consequences such as an increase in flooding,
saltwater intrusion and land subsidence, which in turn decreases rice
production and quality. In addition, natural hazards may amplify the problems created by human activities. Our meta-analysis highlights the ways in which a systems-thinking approach can yield more nuanced perspectives to
tackle “wicked” and interrelated environmental challenges. Given that
deltas worldwide are globally significant for food production and are highly
stressed and degraded, a systems-thinking approach can be applied to provide
a holistic and contextualized overview of the threats faced in each location.

Published: May 2021

Study of the quality of life indicators is an important part of a comprehensive analysis of new diagnosis, treatment, and prevention methods. It can serve as an additional criterion for selecting individual therapy or rehabilitation, examining the ability to work, and identifying psychological problems.
Purpose of the study: The authors took a clinical case to demonstrate the use of внтфьшс monitoring of the quality of life indicators for the assessment of surgical and reconstructive treatment outcome for oral and oropharyngeal cancer.
Results: The anticancer treatment effects were reflected in the physical functioning score according to the EORTC QLQ-C30 questionnaire (reduced to 80 points) and some symptomatic scores according to the EORTC QLQ-C30 and EORTC QLQ-H & N35 questionnaires. Medical rehabilitation measures resulted in positive dynamics of physical functioning scores according to the EORTC QLQ-C30 questionnaire (increase to 93.3 points) and symptomatic scores according to the EORTC QLQ-H & N35 questionnaire related to nutrition. At that, the patient has stopped having difficulty eating in public places; his body weight increased. The absence of pain and refusal to take analgesics also testified to successful treatment and improved quality of life.
Conclusion: A subjective assessment of the various quality of life aspects in a particular patient provides valuable information about the individual response to the conducted treatment.
O discurso médico-científico acerca da relação epilepsia e trabalho: Prescrições, limites e possibilidades ao sujeito trabalhador
Authors: Golfetto Vando , Dametto Jarbas , Moretto Cleide Fátima 
Published: May 2021

O ensaio busca problematizar as concepções relativas à epilepsia e, em especial, ao discurso médico-científico sobre as relações existentes entre essa doença e a vida de trabalho. A partir de uma revisão de literatura não exaustiva, são retomados elementos históricos e conceituais, tendo como objetivo identificar como a epilepsia foi concebida no ocidente até ser encampada pelo saber científico e como esse saber discorreu a respeito da capacitação ou da incapacitação do sujeito acometido para o trabalho remunerado. Constata-se que, declinado o discurso pré-moderno, a ciência médica apropria-se da epilepsia, dando a ela o status de doença orgânica. Entretanto, o estigma, antes incitado por interpretações obscuras, não foi extinto, interferindo na relação do sujeito acometido com o outro, sobretudo quando se compreende que trabalhar é uma forma de relação social, em que o corpo e a subjetividade estão envolvidos. Nota-se que argumentos técnicos sustentados na perspectiva do risco e da segurança geram prescrições limitadoras à vida laboral, leitura esta, ponderada em âmbito acadêmico por discursos que visam preservar a autonomia pessoal na epilepsia, havendo a coabitação desses discursos na contemporaneidade. Os pressupostos foucaultianos relativos a tais discursos, na perspectiva do saber-poder, permitem ampliar a lucidez acerca da efetiva materialidade orgânica desse mal, destacando-a da apreensão discursiva do fenômeno e seus efeitos.

Le travail et son contenu, un angle mort dans les représentations des dirigeants
Authors: Gilbert Patrick , Noël Florent 
Published: May 2021

Les mutations technologiques, économiques et sociales conduisent à faire état d’une « crise du travail ». Or, toute crise appelle des réponses gestionnaires non seulement au niveau macro, mais aussi au niveau micro des organisations productives. Dès lors se pose la question de la manière dont les équipes dirigeantes se saisissent du travail, identifient les enjeux associés et se représentent les actions nécessaires pour répondre à ces défis contemporains. Une enquête réalisée auprès de 33 dirigeants d’entreprises montre que le travail, qu’ils mettent à distance, est largement délégué au management de proximité. Les cadres dirigeants limitent leurs préoccupations à la gestion des seuls salariés sur lesquels reposent leur conception de l’avantage stratégique.

Published: May 2021

Cet article analyse le comportement paradoxal des expatriés de retour frustrés mais fidèles à leur organisation à partir d’une théorie encore émergente en sciences de gestion, celle du don/contre-don de Marcel Mauss. En considérant une expérience d’expatriation comme un « fait social total » qui inclut le passé, le présent et le futur de l’individu et articule l’ensemble des dimensions personnelles et professionnelles, nous proposons une perspective renouvelée sur la période du retour d’expatriation et formulons des préconisations managériales qui prennent en compte les mécanismes nouveaux mis en évidence.

AbstractDual‐ion batteries (DIBs) show the advantages of high working voltage, cost‐effectiveness, and environmental friendliness, but conventional electrolytes commonly cannot satisfy simultaneously the requirements of wide voltage range and high‐concentration, leading to poor cycling durability and limited energy density. In this work, an electrolyte system with 4.0 m lithium bis(fluorosulfonyl)imide (LiFSI) dissolved in tetramethylene sulfone, which shows merits of i) high oxidation potential ≈6.0 V to enable the insertion/deinsertion of FSI− reversibly at the graphite cathode, ii) dramatically suppressed gas formation under high working voltage, and iii) significantly elevated full‐cell DIB energy density, is developed. The DIB constructed with such an electrolyte is able to exhibit 113.3 mAh g−1 capacity and ≈4.6 V medium discharge voltage at 200 mA g−1, along with 94.7% capacity retention after 1000 cycles. Moreover, this DIB delivers an energy density of ≈180 Wh kg−1 (including electrolyte which contributes to the capacity and electrode materials), one of the best performances amongst the related work on DIBs.

AbstractOrganic electrode materials possess many advantages such as low toxicity, sustainability, and chemical/structural tunability toward high energy density. However, to compete with inorganic‐based compounds, crucial aspects such as redox potential, capacity, cycling stability, and electronic conductivity need to be improved. Herein, a comprehensive strategy on the molecular design of small organic electron‐acceptor‐molecule—hexaazatrianthranylene (HATA) embedded quinone (HATAQ) is reported. By introducing conjugated quinone moieties into the electron‐deficient hexaazatriphenylene‐derivative core, HATAQ with highly extended π‐conjugation can yield extra‐high capacity for lithium storage, delivering a capacity of 426 mAh g−1 at 200 mA g−1 (0.4C). At an extremely high rate of 10 A g−1 (19C), a reversible capacity of 209 mAh g−1 corresponding to nearly 85% retention is obtained after 1000 cycles. A unique network of unconventional lock‐and‐key hydrogen bonds in the solid‐state facilitates favorable supramolecular 2D layered arrangement, enhancing cycling stability. To the best of the authors’ knowledge, the capacity and rate capability of HATAQ are found to be the best ever reported for organic small‐molecule‐based cathodes. These results together with density functional theory studies provide proof‐of‐concept that the design strategy is promising for the development of organic electrodes with exceptionally high energy density, rate capability, and cycling stability.

AbstractLow‐valent (MeBDI)Al and (MeBDI)Ga and highly Lewis acidic cations in [(tBuBDI)M+⋅C6H6][(B(C6F5)4−] (M=Mg or Zn,MeBDI=HC[C(Me)N‐DIPP]2,tBuBDI=HC[C(tBu)N‐DIPP]2, DIPP=2,6‐diisopropylphenyl) react to heterobimetallic cations [(tBuBDI)Mg–Al(MeBDI)+], [(tBuBDI)Mg–Ga(MeBDI)+] and [(tBuBDI)Zn–Ga(MeBDI)+]. These cations feature long Mg–Al (or Ga) bonds while the Zn–Ga bond is short. The [(tBuBDI)Zn–Al(MeBDI)+] cation was not formed. Combined AIM and charge calculations suggest that the metal–metal bonds to Zn are considerably more covalent, whereas those to Mg should be described as weak AlI(or GaI)→Mg2+donor bonds. Failure to isolate the Zn–Al combination originates from cleavage of the C−F bond in the solvent fluorobenzene to give (tBuBDI)ZnPh and (MeBDI)AlF+which is extremely Lewis acidic and was not observed, but (MeBDI)Al(F)‐(μ‐F)‐(F)Al(MeBDI)+was verified by X‐ray diffraction. DFT calculations show that the remarkably facile C–F bond cleavage follows a dearomatization/rearomatization route.

AbstractWir berichten über die Synthese trigonaler Imidylcobaltkomplexe [Co(NAryl)L2]−, (L=N(Dipp)SiMe3, Dipp=2,6‐Diisopropylphenyl), mit sehr langen Co‐NAryl‐Bindungen von etwa 1.75 Å. Ihre elektronische Struktur wurde mit einer Vielzahl von physikalischen und spektroskopischen Methoden wie EPR oder Röntgenabsorptionsspektroskopie untersucht, was zu ihrer Beschreibung als höchst ungewöhnliche Imidylcobaltkomplexe führt. Computergestützte Analysen bestätigen diese Ergebnisse und zeigen weiter, dass der High‐Spin‐Zustand für den Imidylcharakter verantwortlich ist. Der Austausch des Dipp‐Substituenten am Imid durch die kleinere Mesitylfunktion (2,4,6‐Trimethylphenyl) bewirkt die unerwartete Me3Si‐Verschiebung vom Ligandenrückgrat zum Imidylstickstoff und offenbart einen hochreaktiven, nukleophilen Charakter der Imidyleinheit.

AbstractLi‐CO2 batteries are regarded as next‐generation high‐energy‐density electrochemical devices. However, the greatest challenge arises from the formation of the discharge product, Li2CO3, which would accumulate and deactivate heterogenous catalysts to cause huge polarization. Herein, Ru(bpy)3Cl2 was employed as a solution‐phase catalyst for Li‐CO2 batteries and proved to be the most effective one screened so far. Spectroscopy and electrochemical analyses elucidate that the RuII center could interact with both CO2 and amorphous Li2C2O4 intermediate, thus promoting electroreduction process and delaying carbonate transformation. As a result, the charge potential is reduced to 3.86 V and over 60 discharge/charge cycles are achieved with a fixed capacity of 1000 mAh g−1 at a current density of 300 mA g−1. Our work provides a new avenue to improve the electrochemical performance of Li‐CO2 batteries with efficient mobile catalysts.
Electronic‐State Manipulation of Surface Titanium Activates Dephosphorylation Over TiO2 Near Room Temperature

Published: May 2021

AbstractDephosphorylation that removes a phosphate group from substrates is an important reaction for living organisms and environmental protection. Although CeO2 has been shown to catalyze this reaction, cerium is low in natural abundance and has a narrow global distribution (>90 % of these reserves are located within six countries). It is thus imperative to find another element/material with high worldwide abundance that can also efficiently extract the phosphate out of agricultural waste for phosphorus recycle. Using para‐nitrophenyl phosphate (p‐NPP) as a model compound, we demonstrate that TiO2 with a F‐modified (001) surface can activate p‐NPP dephosphorylation at temperatures as low as 40 °C. By probe‐assisted nuclear magnetic resonance (NMR), it was revealed that the strong electron‐withdrawing effect of fluorine makes Ti atoms (the active sites) on the (001) surface very acidic. The bidentate adsorption of p‐NPP on this surface further promotes its subsequent activation with a barrier ≈20 kJ mol−1 lower than that of the pristine (001) and (101) surfaces, allowing the activation of this reaction near room temperature (from >80 °C).

AbstractA series of semi‐aromatic copoly(ether ether amide)s (hydroquinone (HQ) (0%)‐HQ (100%)) were synthesized by 1,1‐bis(4‐hydroxyphenyl)‐1‐phenylethane (BHPPE), 1,4‐benzenediol (HQ) and 1,6‐N,N′‐bis(4‐fuorobenzamide) hexane (BFBH) in this work. The inherent viscosities of copoly(ether ether amide)s were in the range of 0.487–0.769 dl g−1. Following with increase of the content of HQ, the resultant polymers were converted from amorphous to crystalline. The copolymers were found to have high glass transition temperatures (Tg) of 141.4–155.6°C and weight‐loss temperature (T5%) of 423.3–434.3°C. They can be hot‐pressed into films with tensile strength of 63.3–87.6 MPa, and storage modulus over 0.8 GPa at about 150°C, indicating good thermal and mechanical property of the obtained copolymers. The results of rheological property showed that the copolymers had good melt flowability and thermal stability. Additionally, the introduction of HQ improved the corrosion resistance of copolymers, the obtained polymers HQ (60%), HQ (80%) and HQ (100%) exhibited better corrosion resistance than that of HQ (0%). Especially, HQ (80%) and HQ (100%) were insoluble in organic polar solvents such as DMSO, DMF because of their crystalline nature, indicating that they had potential to be applied to the corrosion‐resistant materials.
Mono‐ and Di‐Mesoionic Carbene‐Boranes: Synthesis, Structures and Utility as Reducing Agents

Published: May 2021

AbstractMesoionic carbenes (MIC) of the 1,2,3‐triazol‐5‐ylidene type are currently popular ligands in organometallic chemistry. Their use in main group chemistry has been rather limited. In this contribution we present mono‐ and di‐MIC‐boranes with MICs based on triazolylidenes. The synthesis involves in‐situ deprotonation of the corresponding triazolium salts and their reaction with boranes to form the desired compounds. Whereas this reaction route worked well for all triazolium salts derived from the 1,4‐regioisomer of the triazoles, for the methlyene‐bridged bi‐triazolium salt derived from a 1,5‐substiuted triazole, we observed the unexpected decomposition of the bi‐triazolium and the formation of a triazole‐borane with a new N−B bond. All compounds were characterized via multinuclear NMR spectroscopy, mass spectrometry, and single crystal X‐ray diffraction. Furthermore, the MIC‐boranes were used as reducing agents for the reduction of the C=O of aldehydes to the corresponding alcohols.

AbstractPoly(lactide‐co‐glycolide) (PLGA) shows great potentials in biomedical applications, in particular with the field of biodegradable implants and control release technologies. However, there are few systematic and detailed studies on the influence of PLGA degradation behavior on the immunogenicity. In this study, in order to develop a method for dynamically assessing the immunological response of PLGA throughout the implantation process, PLGA particles are fabricated using an o/w single‐emulsion method. The physicochemical characterizations of the prepared PLGA particles during in vitro hydrolytic degradation are investigated. Then, a series of immunological effects triggered by PLGA by‐products formed with degradation process are evaluated, including cell viability, apoptosis, polarization and inflammatory reaction. THP‐1 human cell line is set as in vitro cell model. Our results show that PLGA degradation‐induced acid environment decreases cell viability and increases cell apoptosis, which is a potential factor affecting cell function. In particular, the macrophages exhibit up‐regulations in both M1 subtype related surface markers and pro‐inflammatory cytokines with the degradation process of PLGA, which indicates the degradation products of PLGA can convert macrophages to the pro‐inflammatory (M1) polarization state. All these findings provide the mechanism of PLGA‐induced inflammation and lay the foundation for the design of next‐generation PLGA‐based biomaterials endowed with immunomodulatory functions.
