Abstract:
The structural changes of (NH4)2Pb[Cu(NO2)6] crystals during the phase transitions at 316, 287, and 95 K were studied by means of a single crystal ESR technique. Anisotropic g values [g∥ > g⊥) were obtained in the lowest temperature phase IV, whereas the ESR spectra recorded in the intermediate phases III and II, in which the crystal is known to be tetragonally compressed along the c axis, could be interpreted by use of effective g values [g(∥c) < g(⊥c)]. In the highest temperature phase I an isotropic g value was obtained. The phases I, II, and III o f the present complex can be assumed to be very similar to the corresponding phases observed above ~ 250 K for the compounds R2Pb[Cu(NO2)6] with R = K, Rb, Cs, and Tl. However, the lowest temperature phase transition transforms the phase III with an antiferrodistortive order of the elongated [Cu(NO2)6]4- octahedra into the phase IV with a ferrodistortive one. This occurs only for the complex with R = NH4 and is very unusual. The results of the 14N NQR experiments already reported for the phases III and IV could be well explained by the present newly proposed model.

Abstract:
Small additions of Hf to directionally solidified NiAl–Cr(Mo) eutectic resulted in precipitation of a high density of Heusler phase Ni2AlHf along with fine G-phase Ni16Hf6Si7. The Heusler phase was mainly located on the grain boundary region. The fine G-phase formed in the presence of Si, which was a contamination resulting from contact with ceramic shell molds during directional solidification of the alloy. These fine G-phases were cuboidal in shape and coherent with the NiAl matrix. After hot isostatic pressing and aging treatment, the fine G-phases completely disappeared. The density of the Heusler phase was partially reduced, and the Heusler particles precipitated preferentially on the NiAl/Cr(Mo) interfaces and grain boundaries of the NiAl matrix. Some Heusler particles precipitated locally within the NiAl matrix, and small amounts of them precipitated within the Cr(Mo) phase. The structures of the NiAl/Ni2AlHf and NiAl/Ni16Hf6Si7 interfaces were investigated by high-resolution electron microscopy. The habit plane of the fine G-phase was {001}NiAl. This result was in good agreement with calculation based on the linear elastic theory. The misfit dislocation network on the NiAl/Ni2AlHf (110) interface was calculated from the O-lattice model and compared with the observation, which showed good agreement.

Abstract:
Two models of scalar fields with the interaction Lagrangians gφ4 and [Formula: see text] are considered in ℝ2. There are phase transitions in these models for a certain g = gc. It is shown that the spontaneous symmetry breaking takes place for g > gc. The description of the two phases for g < gc and g > gc is given. The effective coupling constants in perturbation series are less than unity for both the phases so that these models describe the systems with weak coupling. In the second model the "Goldstone" particles have nonzero masses in the phase g > gc.

Abstract:
Previous findings have shown essential connections between linguistic and gustatory stimuli for people with autism or lexical gustatory synesthesia. We examined the associative learning of novel linguistic forms in Japanese as a native language and tastes (candies and chocolates) for healthy people. Healthy subjects performed four phases: (a) evaluation phase of gustatory features; (b) learning phases of novel linguistic form and gustatory stimulus pairs (G) or novel word forms (W); (c) recognition memory phases linked with G and W; and (d) free recall phase for G and W. In the recognition memory phases, the performance scores of W were higher than those of G, while there was no significant difference between response times of G and W. Additionally, no difference between recall performances in G and W was also shown. A subjective evaluation of gustatory features (sweetness) negatively correlated with the recall score for linguistic forms connected to the gustatory feature, whereas the accuracy rates of the recognition memory phase in G positively correlated with those of the free recall phase in G. Although learning of novel linguistic forms is more efficient than learning of the relationships between novel linguistic forms and tastes, gustatory features influence the free recall performances of linguistic forms linked with the tastes. These results may contribute to future applications to word learning not just for patients, but also healthy people.

Abstract:
Quenching of the nanocrystalline high-pressure e phase of iron, which has not been observed under a conventional shock compression, was attained using a femtosecond laser. A small quantity of the g phase of iron also existed. We found that the e phase was induced by the shock itself but not the g phase. The g phase was suggested to be induced as an intermediate structure between the a-e transition. The femtosecond laser driven shock may have the potential to quench high-pressure phases which has not been attained using conventional methods.

Abstract:
Abstract The effects of different doses of transdermal estradiol (TE) on bone mineral density (BMD) in a man with aromatase deficiency were evaluated. The study protocol was divided in the following four phases: phase 1, before estradiol treatment; phase 2, 50 μg TE twice weekly for 6 months; phase 3, 25 μg TE twice weekly for 9 months; and phase 4, 12.5 μg TE twice weekly for 9 months. X-rays of hands, legs, and pelvis were performed, and BMD of the lumbar spine, hormonal parameters (LH, FSH, testosterone, and estradiol), and markers of bone turnover were determined during each phase. BMD in phase 1 was 0.933 g/cm2 and increased to 1.051 and 1.173 g/cm2 after 4 and 7 months of TE, respectively. In phase 3, BMD reached the maximum value (1.275 g/cm2). In phase 4, BMD decreased to 1.180 g/cm2 and was 1.029 g/cm2 at the end of the study protocol. A bilateral necrosis of femoral heads was also detected by x-ray films. In phase 1 serum testosterone was in the normal range, whereas serum estradiol was undetectable. During the 24-month period of treatment with TE (phases 2–4), estradiol was directly related to the amount of TE, whereas LH was inversely related to estradiol serum levels. Estradiol and gonadotropins reached optimal values only in phase 3, when FSH also was near normal; serum testosterone concentrations were normal in phases 3 and 4. This study confirms the role of estrogens in achieving and maintaining bone mineral content in the human male, providing further clinical tools useful in the management of bone loss in aromatase deficiency in the male. We suggest that the adequate substitutive dose of TE for maintaining both bone mass and normal estradiol serum levels in adult men with aromatase deficiency may be 25 μg twice weekly (0.47 μg/kg weekly).

Full text
Abstract:
Les oligopyridine-dicarboxamides et les oligoquinoline-carboxamides sont des oligomères synthétiques capables d’adopter des conformations hélicoïdales stables et bien définies. Les premiers sont comparables à des ressorts moléculaires qui peuvent s’étirer puis s’autoassembler pour former des doubles hélices artificielles. L’étude structurale d’oligopyridines de différentes tailles par diffraction des rayons X et RMN a permis d’éclaircir les principes de l’hybridation en double hélice. Par exemple, nous constatons que la stabilité du duplex est d’autant plus grande que l’oligomère est long mais la cinétique de l’hybridation décroit avec la taille des hélices. Ces propriétés sont modulables en fonction de divers paramètres tels que le solvant ou les substituants des pyridines. Les seconds forment de simples hélices moléculaires stables dans les solvants organiques mais aussi dans l’eau. Nous avons développé leur synthèse sur support solide afin de disposer de séquences variées, à l’image des alpha-peptides. Des études par RMN suggèrent que l’introduction d’unités aminométhylpyridines au sein d’un oligoquinoline hydrosoluble apporte de la flexibilité sans perturber sa structure hélicoïdale. Cela témoigne de la stabilité de ces structures secondaires dans les solvants protiques. Par ailleurs, certains de ces peptidomimes s’avèrent capables de reconnaitre et stabiliser des motifs structuraux particuliers de l’ADN : les G-quadruplex. Etant donné que ces architectures se forment à des endroits clés du génome impliqués dans des cancers, ces hélices moléculaires font figure de potentiels agents antitumoraux d’un nouveau genre
Oligopyridine-dicarboxamides and oligoquinoline-carboxamides are synthetic oligomers able to fold into stable and well defined helical conformations. The first ones are comparable to molecular springs which can extend then associate to form artificial double helices. A structural study of oligopyridines of various sizes by X-ray diffraction and NMR provided a better understanding of the hybridization process. For example, we noticed that the stability of the duplex is all the higher as the oligomer is long but the kinetics of hybridization decrease with length. These properties depend on diverse parameters such as the solvent or the substituants of pyridine rings. The second family forms stable single helices in organic solvents and also in water. We adapted their synthesis on solid support to promote accessibility to a variety of sequences, just like for alphas-peptides. NMR studies suggested that the introduction of aminomethylpyridine units within a hydrophilic oligoquinoline strand brings some flexibility without disrupting its helical structure, showing the high stability of these secondary structures in protic solvents. Besides, some of these peptidomimetics turn out to be capable of recognizing and stabilizing a particular DNA motif: G-quadruplex structure. Given that these architectures form in critical places of the genome involved in cancers, these molecular helices may represent a new class of potential antitumoral agents

Full text
Abstract:
Les aciers inoxydables austéno-ferritiques moulés sont utilisés pour certains composants ducircuit primaire des centrales nucléaires de génération II. Aux températures de service (285 °C -325 °C), des modifications de propriétés mécaniques sont observées. Elles sont imputables auxtransformations de phases au sein de la ferrite de ces aciers : la décomposition spinodale (DS) en phaseα (riche en Fe) et α’ (riche en Cr) et la précipitation de la phase G aux interfaces α/α'. S'il est admisque la composition de l’acier influe sur l’évolution des transformations de phase de la ferrite (lesaciers moins riches en Ni et Mo sont moins sensibles au vieillissement), aucune étude, à ce jour, n'apermis de mettre en évidence l'influence du Ni, Mo, Mn et des synergies éventuelles sur levieillissement des aciers ni de déterminer la contribution de la phase G à l'évolution des propriétésmécaniques. Dans cette étude, les cinétiques des transformations de phase de la ferrite d'aciers inoxydable austéno-ferritiques pauvres en Mo et riches en Mo ainsi que de celle d'alliages modèles decomposition ciblée ont été étudiées par sonde atomique tomographique (SAT) et par mesure demicrodureté. Les travaux ont répondu aux trois questions suivantes : - Quantification de la contribution des différentes phases au durcissement : L'utilisation conjointe de modèles de durcissement et des données obtenues par la sonde a montré que, contrairement à ce qui était dit dans la littérature, la phase G est le contributeur majoritaire au durcissement pour les aciers avec Mo. Ce n'est qu'aux temps longs, lorsque la coalescence des particules de phase G intervient et que la DS est plus développée que la contribution de la DS devient prépondérante. Ceci est dû à la forte densité de particules de phase G dans ces aciers. Dans le cas des aciers sans Mo qui contiennent dix fois moins de particules en début de cinétique, la phase G et la DS ont des contributions équivalentes. – Influence du Ni, Mo et Mn : L’étude d’alliage modèles de compositions ciblées a montré que seul le Ni accélère la décomposition spinodale et que le Mn a un rôle prépondérant dans la formation des particules de phase G aux interfaces α/α’. - Efficacité d'un traitement thermique de régénération à 550 °C: Une alternative au remplacement des composants les plus vieillis pourrait être un traitement thermique dit de régénération. Les recuits à 550 °C permettent de restaurer entièrement les aciers sans Mo et partiellement les aciers avec Mo. Ceci est dû au fait que les particules de phase G ne sont pas entièrement dissoutes dans le cas des aciers avec Mo, induisant un durcissement résiduel. Dans tous les cas, la DS est entièrement dissoute
Cast austenitic-ferritic stainless steels are used in primary circuit of 2nd generation nuclearpower plants. At operating temperature (285 °C - 325 °C), evolution of mechanical properties isobserved due to the phase transformations occurring within the ferrite: spinodal decomposition (SD)leading to the formation on a Fe rich phase (α) and a Cr rich phase (α ') and the precipitation of the G-phase at α/α' interfaces. This evolution of the mechanical properties can be prohibitive for thecomponents. If it is well known that the steel composition plays an important role on the evolution ofthe properties (steels less rich in Ni and Mo are less sensitive to aging), the role of solute elements asNi, Mo and Mn on the aging kinetics is not yet known so as the contribution of the G-phase on thehardening during the thermal aging. In this study, the aging kinetics of the ferrite of some austenitic-ferritic stainless steels with or without Mo and model alloys with tuned compositions have been studied by atom probe tomography (APT) and by micro hardness measurements. This works answered the three following questions: - Quantification of the contribution of both spinodal decomposition and G-phase precipitation on hardening of the ferrite: combination of hardening models and data obtained with APT permitted to show that G-phase precipitation is clearly the main contributor to ferrite hardness increase at early stage of ageing in Mo-bearing steels. This is due to the high number density of G-phase particles. In Mo-free steels which have ten times less G-phase particles, contributions of both spinodal decomposition and G-phase precipitation are similar. In both cases, when coarsening of G-phase particles occurs and SD is well developed, SD contribution becomes larger. - Influence of Ni, Mo and Mn on aging kinetics: The study of model alloys with tuned composition has shown that only Ni plays a role on SD by enhancing the decomposition. Mn is a key element for the precipitation of G-phase particles at α/α' interfaces. - Efficiency of regeneration heat treatment at 550 °C: an alternative to component replacement is to perform a heat treatment at higher temperature in order to restore the properties of the components. The heat treatments performed permitted to entirely restore the mechanical properties of Mo free steels and partially the properties of Mo bearing ones. This is due to the presence of undissolved G-phase particles in the case of Mo bearing alloys. In each case, SD was totally dissolved

Abstract:
Au cours de son refroidissement, de la temperature du solidus a la temperature ambiante, la fonte a graphite spheroidal ferritique subit une transformation de phase. Cette derniere lui attribue un comportement complexe faisant apparaitre des interdependances entre la reponse mecanique, la reponse thermique et le changement microstructural. En particulier, l'influence de l'evolution de la microstructure sur le comportement mecanique se traduit par non seulement des modifications des caracteristiques mecaniques mais aussi l'apparition d'autres phenomenes tels que la plasticite de transformation de phase et la dilatation thermo-metallurgique due a la variation volumique au cours du changement microstructural. Hors du domaine du changement de phase, le materiau etant forme d'une seule phase, nous nous proposons de modeliser son comportement par un modele elasto-viscoplastique anisotherme base sur la thermodynamique des processus irreversibles avec variables internes. Quant a la description du comportement du materiau biphasique au cours de la transformation de phase, elle est basee sur la theorie des melanges avec une approches simplifiee qui consiste a prendre la deformation totale et la temperature comme variable commune aux deux phases presentes dans le materiau (modele de voigt). Par ailleurs, pour modeliser le changement de phase une variable interne supplementaire est introduite. Elle represente la fraction volumique de la phase naissante. L'utilisation des couplages d'etat, de dissipation et d'evolution permettent, quant a eux, de tenir compte des interactions qui existent entre les differents mecanismes mis en jeu dans le comportement de la fonte etudiee et ainsi de preciser la forme de chacun des potentiels thermodynamiques et de dissipation. Les lois de comportement, qui en decoulent, permettent la description du comportement elasto-viscoplastique anisotherme du materiau avec prise en compte de la transformation de phase. Pour identifier les parametres de la loi proposee, nous avons effectue une importante campagne d'essais isothermes et anisothermes (traction, fluage, relaxation, dilatation, resistivite. . . ). Une comparaison entre les essais de verification et le modele est effectuee ou l'on note une bonne prevision du modele pour l'ensemble des phenomenes pris en compte

Six places-échantillons représentatives de la séquence temporelle écologique associée à la dégradation du pergélisol ont été sélectionnées sur un plateau silteux à pergélisol riche en glace à proximité d'Umiujaq, au Nunavik. Le présent travail a pour objectif de déterminer les changements qui se produisent dans les flux de chaleur entre les trois niveaux de l'écosystème (végétation / couverture de neige, couche active, pergélisol) ainsi que les rétroactions qui surviennent lors de la dégradation du pergélisol et à quantifier la vitesse de la transition à partir de photographies aériennes et la dendrochronologie. Pour répondre aux objectifs, la méthodologie utilisée suit le protocole du programme Adaptation et Dévelopement de l’Arctique sur le Pergélisol en Transition (ADAPT), intégrant l’analyse de données écologiques, climatiques, stratigraphiques et thermiques. Les résultats obtenus illustrent une évolution exponentielle des facteurs de dégradation du pergélisol sur une période estimée à environ 90 ans; lent durant les 60 premières années, et significativement plus rapide durant les 30 dernières années.
Six plots, representative of the regional ecological time sequence associated with permafrost degradation, were selected on a silty ice-rich permafrost plateau near Umiujaq, Nunavik. The objective of the present work is to determine the changes that occur in the flow of energy between the three layers of the ecosystem (vegetation / snow cover, active layer, permafrost) and the feedbacks that occur during the degradation of permafrost and to quantify the rate of the transition using time-lapse aerial photographs and tree ring analysis. In order to respond to these objectives, the methodology follows the ADAPT (Arctic Development and Adaptation on Permafrost in Transition) protocol, including ecological, climate, stratigraphic and thermal data analysis. The results show exponential evolution of permafrost degradation factors over a period of time of about 90 years; slowly during the first 60 years, and significantly faster during the last 30 years.

Abstract:
AbstractBased on disassembly studies, a life cycle assessment of the climate impact of the wireless over-ear headphone model Jabra Evolve2 85 (without charging station) is conducted regarding the life cycle phases of manufacturing, packaging, distribution, use and disposal. The total weight of all components is 280.7 g. The materials can be categorized into polymers (61.7%), metals (20.9%), circuit boards (4.8%), Li-ion battery (4.6%), foam (3.5%), cables (3.0%) and unidentifiable polymers (1.7%). The functional unit is defined as the wireless audio transmission through a stereo headphone over its lifetime. The lifecycle assessment results in a global warming potential of 12.17 kg CO2-Eq with a contribution of the manufacturing phase of 81.2%, based on an assumed lifetime of 2,600 using hours. In the context of a sensitivity analysis, a repair scenario of a battery replacement of the over-ear headset is modelled. Assuming a doubled lifetime, the global warming potential per hour is reduced from 4.7 g CO2-Eq/h to 2.4 g CO2-Eq/h.

AbstractIntuitionistic Strong Löb logic $$\textsf{iSL}$$ iSL is an intuitionistic modal logic with a provability interpretation. We introduce $$\textsf{GbuSL}_{\Box } $$ GbuSL □ , a terminating sequent calculus for $$\textsf{iSL}$$ iSL with the subformula property. $$\textsf{GbuSL}_{\Box } $$ GbuSL □ modifies the sequent calculus $$\textsf{G3iSL}_{\Box } $$ G 3 iSL □ for $$\textsf{iSL}$$ iSL based on $$\textsf{G3i} $$ G 3 i , by annotating the sequents to distinguish rule applications into an unblocked phase, where any rule can be backward applied, and a blocked phase where only right rules can be used. We prove that, if proof search for a sequent $$\sigma $$ σ in $$\textsf{GbuSL}_{\Box } $$ GbuSL □ fails, then a Kripke countermodel for $$\sigma $$ σ can be constructed.

Abstract:
AbstractWe give a brief description of the results obtained by Prof. Sergey G. Psakhie and his colleagues in the field of theoretical studies of mechanical response, including fracture, of permeable fluid-saturated materials. Such materials represent complex systems of interacting solid and liquid phases. Mechanical response of such a medium is determined by processes taking place in each phase as well as their interaction. This raised a need of developing a new theoretical approach of simulation of such media—the method of hybrid cellular automaton that allowed describing stress-strain fields in solid skeleton, transfer of a fluid in crack-pore volume and influence of fluid pressure on the stress state of the solid phase. The new method allowed theoretical estimation of strength of liquid-filled permeable geomaterials under complex loading conditions. Governing parameters controlling strength of samples under uniaxial loading and shear in confined conditions were identified.

Abstract:
Abstract Void fraction measurements for adiabatic, two-phase vertical upward, water-air flow in a 9.53 mm ID tube were obtained using a helical wound capacitance sensor. Comparisons were made between 1-g and μ-g void fraction values by matching the flow rates obtained at μ-g conditions. A Probability Density Function was used to analyze the void fraction signals. It was found that a wider fluctuation in void fraction values occurred for slug flow at 1-g as compared to μ-g. For higher flow rates such as with annular flow, inertia forces become dominant. For these flows it was found that the void fraction fluctuations were similar at 1-g and μ-g conditions.

Abstract:
Community-Leave No One Behind (CLNOB) is a new participatory approach to identify both challenges and solutions in community's journeys towards ODF-S. It has been designed to be integrated into Phase II of the Swachh Bharat Mission-Grameen (SBM-G). The government of India has issued the guidelines for Phase II of SBM-G, of which one of the guiding principles is ensuring that no one is left behind. CLNOB demonstrates a way to achieve this goal. It encourages communities to identify gaps in sanitation coverage and use and promote actions they can take themselves. The purposes of this handbook are two-fold: first to inform policymakers and stakeholders at all levels about this new initiative, and second to provide guidance to facilitators and practitioners for CLNOB implementation. This handbook is a living document and will be updated and refined after more field experiences are conducted. It is based on limited experience from a small pilot carried out between June and October 2020 during the challenging environment of the COVID-19 pandemic.

Abstract:
Review question / Objective: In recent years, many articles have shown the significant clinical effects of traditional Chinese medicine for esophageal cancer (EC) treatment. These studies involved Chinese medicine injection, decoction, acupuncture, and moxibustion. Chinese medicine injections, including Aidi injection (Aidi) (Z52020236, China food and Drug Administration; composed of 0.15 g/ml cantharis, 5 g/ml ginseng, 10 g/ml Astragalus and 15 g/ml Eleutherococcus senticosus at a ratio of 0.03:1:2:3. The three plant names have been checked with http://www.theplantlist.org 2022/6/4), Shenqifuzheng injection, Kanglaite injection, compound Kushen injection, and Kangai injection, are widely used to treat cancer in clinical practice because of their efficacy and convenience. Aidi combined with standard treatment, including chemotherapy, radiotherapy, or chemoradiotherapy (CR) (Aidi-based combination therapy), showed significant efficacy in the treatment of unresectable EC. However, existing studies are limited to small sample sizes, and the efficacy of Aidi in the treatment of unresectable EC has not been confirmed in large-scale phase III clinical trials. Therefore, it is important to derive more convincing results by analyzing all the reported data. Herein, we conducted a literature search for all randomized controlled trials (RCTs) that applied Aidi-based combination therapy in unresectable EC treatment, and a meta-analysis was performed to evaluate the efficacy of Aidi-based combination therapy in unresectable EC treatment.

Grafi, Gideon, and Brian Larkins. Endoreduplication in Maize Endosperm: An Approach for Increasing Crop Productivity. United States Department of Agriculture, September 2000. http://dx.doi.org/10.32747/2000.7575285.bard.

Full text
Abstract:
The focus of this research project is to investigate the role of endoreduplication in maize endosperm development and the extent to which this process contributes to high levels of starch and storage protein synthesis. Although endoreduplication has been widely observed in many cells and tissues, especially those with high levels of metabolic activity, the molecular mechanisms through which the cell cycle is altered to produce consecutive cycles of S-phase without an intervening M-phase are unknown. Our previous research has shown that changes in the expression of several cell cycle regulatory genes coincide with the onset of endoreduplication. During this process, there is a sharp reduction in the activity of the mitotic cyclin-dependent kinase (CDK) and activation of the S-phase CDK. It appears the M-phase CDK is stable, but its activity is blocked by a proteinaceous inhibitor. Coincidentally, the S-phase checkpoint protein, retinoblastoma (ZmRb), becomes phosphorylated, presumably releasing an E2F-type transcriptional regulator which promotes the expression of genes responsible for DNA synthesis. To investigate the role of these cell cycle proteins in endoreduplication, we have created transgenic maize plants that express various genes in an endosperm-specific manner using a storage protein (g-zein) promoter. During the first year of the grant, we constructed point mutations of the maize M-phase kinase, p34cdc2. One alteration replaced aspartic acid at position 146 with asparagine (p3630-CdcD146N), while another changed threonine 161 to alanine (p3630-CdcT161A). These mutations abolish the activity of the CDK. We hypothesized that expression of the mutant forms of p34cdc2 in endoreduplicating endosperm, compared to a control p34cdc2, would lead to extra cycles of DNA synthesis. We also fused the gene encoding the regulatory subunit of the M- phase kinase, cyclin B, under the g-zein promoter. Normally, cyclin B is expected to be destroyed prior to the onset of endoreduplication. By producing high levels of this protein in developing endosperm, we hypothesized that the M-phase would be extended, potentially reducing the number of cycles of endoreduplication. Finally, we genetically engineered the wheat dwarf virus RepA protein for endosperm-specific expression. RepA binds to the maize retinoblastoma protein and presumably releases E2F-like transcription factors that activate DNA synthesis. We anticipated that inactivation of ZmRb by RepA would lead to additional cycles of DNA synthesis.
