El estudio se llevó a cabo en alianza con el Ministerio de Fomento, Industria y Comercio (MIFIC) y la Cámara Nicaragüense de tabacaleros (CNT). El objetivo de la investigación fue evidenciar la incidencia de los procesos de pre industria e industria y variables ambientales en las características organolépticas de la hoja de tabaco producida en Nicaragua. Para la recolección de información se aplicaron métodos cualitativos y cuantitativos. Para el análisis de los datos se aplicó estadística descriptiva e inferencial. En la pre industria e industria para el procesamiento de la hoja de tabaco se realizan las siguientes etapas: recepción y control de calidad de la hoja de rango óptimo (20-30ºC), tabaco, fermentación de las hojas de tabaco, añejamiento, despalillo, elaboración de puros, empaque. Es importante destacar que la etapa de fermentación se considera un punto de control para la conservación y desarrollo de la calidad de los atributos de las hojas de tabaco (aroma, sabor, color, textura, combustión, color de ceniza). La hoja de tabaco de Estelí presenta sabores fuertes, aroma con ligeras notas a café, color de tabaco café oscuro, textura gruesa y por ende velocidad de combustión lenta y genera ceniza de color gris; por su parte las hojas de tabaco de Condega producen sabores fuertes y dulces, aroma con ligeras notas a chocolate, color de tabaco que va de colorado oscuro a café oscuro, textura media, velocidad de combustión que va de media a lenta y color de ceniza gris. La hoja de tabaco procedente de Jalapa y Ometepe se caracterizan por sabores suaves y aromas relacionados con el aroma de las flores y el cuero; las hojas son de textura de media a delgada y velocidad de combustión lenta, colores de tabaco con tonalidades claras que van de colorado a colorado claro y color de ceniza blanca. Estas diferencias en los atributos del tabaco permiten a las empresas crear diferentes mezclas para la elaboración de puros con diversos sabores, aromas y colores. Es preciso destacar que los puros se confeccionan completamente a mano y la experiencia de los colaboradores influye en la calidad, los cuales son reconocidos a nivel internacional y actualmente se posicionan entre los mejores puros del mundo. Las variables ambientales que inciden en los atributos de la hoja de tabaco son principalmente la temperatura y el suelo.

Published: December 2019

Malgré les diverses campagnes de communication sur la vaccination en France, un problème de confiance persiste envers ce traitement préventif. De nombreux travaux traitent du rapport d’un individu à la vaccination, mais majoritairement dans une approche atomisée, en se focalisant sur une particularité de ce traitement (type de maladie…). Cette recherche étudie le rapport des individus à la vaccination de manière holistique en analysant les avis en ligne d’un échantillon ayant participé à la « Concertation citoyenne de la vaccination ». Le corpus de cette étude qualitative (5 702 avis recueillis) a fait l’objet d’une analyse lexicale automatisée. Quatre thèmes principaux apparaissent : acteurs/intérêts et conflits d’intérêt ; décision vaccinale (choix/obligation) ; objectifs et conséquences attendues de la vaccination ; actions, prévention et proximité. L’originalité de cette recherche réside dans l’analyse sémiotique de la structure de ces classes et permet de mieux comprendre les sens et non-sens de la vaccination en France.
Don du sang : comprendre la logique des donneurs et la valeur du don pour encourager le recrutement et la fidélisation des donneurs
Authors: Boch Emmanuelle , Giannelloni Jean-Luc 
Published: December 2019

Avec des besoins en hausse, la collecte de sang est une priorité en matière de santé publique. Or le don du sang, bien que valorisé socialement, n’est pratiqué que par 4 % des individus en capacité de le faire, selon l’Etablissement Français du Sang. En s’appuyant sur un cadre théorique mêlant les théories du don et de la valeur, cet article vise à comprendre comment les individus deviennent donneurs et le restent. Pour cela, il se focalise à la fois sur les différentes étapes qui précèdent le passage à l’acte et sur les bénéfices retirés du don, qui en favorisent la répétition. Une étude qualitative focalisée sur les donneurs et combinant des entretiens semi-directifs, une immersion sur le terrain et des matériaux visuels, permet 1) de rendre compte des processus individuels et sociaux favorisant l’acte de don, 2) de souligner les bénéfices que les donneurs retirent de la réalisation et de la répétition de cette pratique et 3) de fournir des recommandations opérationnelles afin de recruter et de fidéliser des donneurs.

Expanding Experiential Learning in Contemporary Adult Education: Embracing Technology, Interdisciplinarity, and Cultural Responsiveness
Authors: Dillard Nicole , Sisco Stephanie , Collins Joshua C. 
Published: December 2024

ABSTRACTThis article explores the evolution and expansion of experiential learning theory (ELT) within the context of contemporary adult education, emphasizing the integration of technology, interdisciplinarity, and cultural responsiveness. Although Kolb's foundational model has been instrumental in linking theoretical knowledge with practical application, its limitations—particularly in addressing the complexities of modern learning environments—are critically examined. The authors advocate for an expanded ELT framework incorporating interdisciplinary approaches to enrich adult learning experiences. By integrating digital tools, considering socio‐political contexts, and fostering collaboration, the article proposes a more inclusive and adaptable model that better aligns with the diverse needs of today's adult learners. This reconceptualization aims to enhance the relevance and efficacy of ELT, ensuring it remains a vital tool for personal, professional, and societal development in a rapidly changing world.

Impact Driven Liquid Encapsulation: Promises, Development, and Future Prospects
Authors: Misra Sirshendu , Mitra Sushanta K. 
Published: December 2024

AbstractEncapsulation creates a protective outer layer(s) around a core cargo, which safeguards the cargo in aggressive surroundings. It also serves as a platform to impart various desired characteristics to the core cargo, including shell‐functionalization and targeted release characteristics. Encapsulation can be broadly classified into three categories: physical, chemical, and physicochemical techniques. This perspective focuses on an emerging class of impact‐driven physical encapsulation techniques, which offers several lucrative prospects compared to conventional encapsulation methods, including straightforward execution and ultrafast yet controlled wrapping. Two different categories of impact‐driven methods for achieving stable, ultrafast encapsulation of various core liquid analytes with one or more wrapping layers are discussed, namely, elastocapillary wrapping with ultrathin sheet(s) and a liquid–liquid encapsulation framework, where thin liquid film(s) are used to wrap liquid analytes, with an emphasis on the latter. The promising prospects of both approaches are discussed, recent developments are outlined, and areas of future research that can lead to a truly versatile and comprehensive encapsulation platform applicable to a broad range of practical applications are highlighted.

Published: December 2024

AbstractPhotoelectrochemical (PEC) technology is one of the most promising methods for converting solar energy into valuable fuels and chemicals. Silicon (Si), a narrow band gap semiconductor with high carrier mobility, serves as a competitive material for photoelectrodes. This review outlines the research progress of Si‐based photoanodes and photocathodes in diverse economically beneficial PEC redox reactions, extending beyond water splitting to include alcohol oxidation, carbon dioxide reduction, ammonia synthesis, organic degradation, and more. To address the key barriers to achieving efficient PEC conversion – such as slow charge carrier dynamics, sluggish reaction kinetics, and the instability of Si‐based photoelectrodes – the mechanisms and implementation methods for fabricating efficient and stable Si‐based photoelectrodes are thoroughly discussed. Finally, the challenges faced in advancing the commercialization of Si‐based PEC solar energy conversion processes are explored.

AbstractTwo‐dimensional (2D) materials are widely used in various optical, electronic, and optoelectronic devices. However, the realization of visible light emission and near‐infrared photodetection functions in a single device remains a challenge. Here, an integrated dual‐functional device is developed by manipulating the excitons of WS2 within a graphene/hBN/WS2/graphene heterostructure. When operating as a photodetector at low external bias, the dark current is well suppressed by the hBN layer. With the excellent two‐photon absorption (TPA) property of monolayer WS2, the photoresponse range of the photodetector can be extended to the near‐infrared region, achieving a responsivity of up to 0.19 mA/W at 1145 nm. At high external bias, the device can work in light‐emitting mode, in which the electroluminescence (EL) wavelength can be tuned via gate voltage. This atomically thin device opens up possibilities for applications in miniaturized display, sensing, and monitoring systems.
A practical, reproducible laboratory method for assessing soil aggregate stability
Authors: Monteith Steven , Seybold Cathy , Nelson Kate 
Published: December 2024

AbstractSoil aggregate stability is an important soil physical measurement that is closely related to a range of soil health functions. It is defined by its analytical method and often within‐method variability and inter‐method comparability have not been addressed and quantified. The current Natural Resources Conservation Service Kellogg Soil Survey Laboratory (KSSL) method for analyzing aggregate stability uses non‐standardized equipment and hand‐sieving techniques and is not easily scalable. The objective of this study was to evaluate and modify an alternative method that uses a single sieve mechanical wet sieving apparatus (MWS method) to produce results comparable to the current KSSL method and evaluate another alternative method that uses multiple sieves in a custom‐fabricated Yoder‐type apparatus. The two methods were evaluated for efficiency, repeatability, and scalability. The MWS method uses standardized equipment and methods, which should be scalable and reproducible in different laboratories. Sample preparation, pretreatment, and sieving parameters of the MWS method were adjusted to produce analytical results which most closely matched the KSSL method. Repeated analysis of soil sample standards showed that within‐method variability of the MWS method was slightly less than in the KSSL method. In a comparison of 90 samples of widely varying properties, Lin's concordance correlation coefficient was 0.927, indicating a moderate strength of agreement between the MWS method and KSSL method. Results from a modified Yoder method were not comparable to the KSSL method, and the greater time requirements, procedural complexity, and large equipment footprint were identified as practical limitations for use in large‐scale laboratory applications.

AbstractAutophagy is a ubiquitous process of organelle interaction in eukaryotic cells, in which various organelles or proteins are recycled and operated through the autophagy pathway to ensure nutrient and energy homeostasis. Although numerous fluorescent probes have been developed to image autophagy, these environment‐responsive probes suffer from inherent deficiencies such as inaccuracy and limited versatility. Here, we present a modular macrocyclic amphiphile Förster Resonance Energy Transfer (FRET) platform (SC6A12C/NCM, SN), constructed through the amphiphilic assembly of sulfonatocalix[6]arene (SC6A12C) with N‐cetylmorpholine (NCM) for lysosome targeting. The hydrophobic fluorophore BPEA (FRET donor) was entrapped within the inner hydrophobic phase and showed strong fluorescence emission. Attributed to the broad‐spectrum encapsulation of SC6A12C, three commercially available organelle probes (Mito‐Tracker Red, ER Tracker Red, and RhoNox‐1) were selected as SC6A12C guests (FRET acceptors). During autophagy process, the formation of intracellular host–guest complexes leads to strong FRET signal, allowing us to visualize the fusion of mitochondria, endoplasmic reticulum, and Golgi apparatus with lysosomes, respectively. This study provides a versatile and accessible platform for imaging organelle autophagy.

Published: December 2024

AbstractModifying the separator is considered as an effective strategy for achieving high performance lithium‐sulfur (Li‐S) batteries. However, most modification layers are excessively thick, with catalytic active sites primarily located within the material′s interior. This configuration severely impacts Li+ transport and the efficient catalytic conversion of polysulfides. Therefore, there is an urgent need to develop a multifunctional separator that integrates ultrathin design, catalytic activity, and ion sieving capabilities. Herein, we successfully linked TCPP(Ni) as a secondary ligand with Zr‐BTB nanosheets to create an ultra‐thin separator modification layer (Zr‐TCPP(Ni)) with efficient ion sieving and catalytic properties. The resultant multifunctional separators provide robust ion sieving capabilities that promote rapid Li+ transport and intercept polysulfides shuttling. Therefore, The Zr‐TCPP(Ni)@PP cell maintains 70.0 % of its initial capacity after 600 cycles at a high rate of 3 C, while achieving an impressive areal capacity of 4.55 mA h cm−2 even with high sulfur content of 80 wt% at 0.5 C. This work provides valuable insights for rational design of MOF interface engineering in high energy density Li‐S batteries.

ABSTRACTSix novel binuclear complexes have been reported in this paper: [Ln(2‐Cl‐6‐FBA)2(5,5′‐DM‐2,2′‐bipy)(NO3)]2, (Ln = Nd(1), Pr(2)); [Ln(2‐Cl‐6‐FBA)3(5,5′‐DM‐2,2′‐bipy)(H2O)]2, (Ln = Gd(3), Er(4), Eu(5), Ho(6); 2‐Cl‐6‐FBA = 2‐chloro‐6‐fluorobenzoate; 5,5′‐DM‐2,2′‐bipy = 5,5′‐dimethyl‐2,2′‐bipyridine). The complexes underwent comprehensive characterization, incorporating both elemental analysis and X‐ray diffraction (XRD) methodologies. The subsequent X‐ray single‐crystal structure diffraction analysis illuminated the existence of diverse coordination characteristics within these complexes: the coordination number of complexes 1 and 2 is 9, and the coordination number of complexes 3–6 is 8. The fluorescence spectra of complex 5 were obtained by fluorescence test. The detailed decomposition processes of the six complexes were studied by TG‐DTG‐DSC/FTIR technique. The nonisothermal kinetics of complex 6 at the third step were discussed by using M. J. Starink method, NL‐INT method, and double equal‐double step method.

Published: December 2024

ABSTRACTBackgroundCurrent US federal action levels for domoic acid (DA) in seafood are based on acute toxicity observed in exposed adult humans. Life course considerations have not been incorporated. The potential for developmental neurotoxicity (DNT) at permissible DA levels has previously been noted, but not methodically assessed.MethodsStudies of DNT following DA exposure in experimental and wild animals were identified through a comprehensive search strategy. Evidence from papers meeting inclusion criteria was evaluated for specific outcomes reported for doses at which adverse effects were observed. Exposure levels associated with DNT were compared with those known to cause adult toxicity. The findings are discussed in the context of the well‐characterized mechanism of DA neurotoxicity, as well as the toxicokinetics of DA across species and life stages.ConclusionsDNT outcomes were reported with a no observed adverse effect level (NOAEL) 10 times lower than the NOAEL of 0.75 mg DA/kg for acute effects in adults. Apart from reviewing current regulatory action levels, public health outreach messaging to health care professionals and sensitive populations, such as pregnant or breastfeeding women, should be considered as a means of increasing awareness about risk for DNT from consumption of potentially DA‐contaminated seafood.
How Small Proteins Adjust the Metabolism of Cyanobacteria Under Stress
Authors: Kraus Alexander , Hess Wolfgang R. 
Published: December 2024

ABSTRACTSeveral recently discovered small proteins of less than 100 amino acids control important, but sometimes surprising, steps in the metabolism of cyanobacteria. There is mounting evidence that a large number of small protein genes have also been overlooked in the genome annotation of many other microorganisms. Although too short for enzymatic activity, their functional characterization has frequently revealed the involvement in processes such as signaling and sensing, interspecies communication, stress responses, metabolism, regulation of transcription and translation, and in the formation of multisubunit protein complexes. Cyanobacteria are the only prokaryotes that perform oxygenic photosynthesis. They thrive under a wide variety of conditions as long as there is light and must cope with dynamic changes in the environment. To acclimate to these fluctuations, frequently small regulatory proteins become expressed that target key enzymes and metabolic processes. The consequences of their actions are profound and can even impact the surrounding microbiome. This review highlights the diverse functions of recently discovered small proteins that control cyanobacterial metabolism. It also addresses why many of these proteins have been overlooked so far and explores the potential for implementing metabolic engineering strategies to improve the use of cyanobacteria in biotechnological applications.
Systematic Investigations of the Solid Solution Zr(V1–xAlx)2 Adopting the Laves Phase Structures

Published: December 2024

AbstractLaves phases are an interesting field of research when it comes to structural chemistry and physical properties. Investigations of the ternary system Zr–V−Al showed, in contrast to the system Hf–V−Al, that no superstructures can be observed within the solid solution Zr(V1–xAlx)2. High values of x form aluminum rich phases that adopt the hexagonal MgZn2 type structure while low values of x lead to vanadium rich phases that adopt the cubic MgCu2 type. All samples were investigated by powder X‐ray diffraction experiments. Single crystal studies indicated that no superstructure formation is present in the investigated samples. 27Al MAS NMR investigations confirmed these findings. For ZrAl2, quantum‐chemical calculations helped with the analysis of the 27Al NMR spectrum of the binary endmember of the solid solution. Some of the prepared samples were investigated with respect to their magnetic properties. The investigated compounds show Pauli‐paramagnetism, in Zr(V0.875Al0.125)2 in addition superconductivity with a critical temperature of TC=4.17(1) K was observed. Investigations of compositions that do not belong to the Laves phase regime clearly indicate that the MgZn2 type structure is still the dominant phase. Regardless of the starting composition chosen, the hexagonal Laves phase was mostly present.
