description: In a solvent extraction process, the compositions of the phases in thermodynamic equilibrium (described as a Winsor-II regime) must be determined to obtain the extraction isotherms of ions as well as co-extracted water. By comparing the extractions of a series of acids by the malonamide DMDOHEMA (N,N’-dimethyl-N,N’-dioctyl hexylethoxy malonamide) in n-heptane, the specific anion effects regarding third phase formation and the strength of the acid-extractant interaction were investigated. It is shown that third phase formation is driven by hydration enthalpy of acid, while the polar core microstructure is controlled by the pKa of the acids. Upon acid extraction, the promotion of third phase formation follows the series H2SO4 ≈ H3PO4 ≈ HClO4 > HNO3 > HCl > HCOOH, which correlates to hydration enthalpy of acid in the case of monoacids. The combination of IR spectroscopy and DFT calculations revealed two different modes of acid extraction, either by hydrogen bonding (extraction of non-dissociated acid: HA) or by protonation of the extractant (extraction of dissociated acid: H+A−). The strength of the amide-acid interaction (protonation vs. hydrogen bonding) is correlated to the pKa of the acid and is responsible for the microstructure of the solution.

A mechanism involving three tributylphosphate molecules for one molecule of undissociated gallic acid with co-extraction of water was found in LLE. ELM process is as fast as LLE and more efficient; in addition, it is more environmentally-friendly because lower extractant concentrations and smaller organic phase volumes were needed.

description: We previously studied the effects of 2–100 kGy gamma radiation (generated from 6°Co) on physicochemical, thermal, morphological, and antimicrobial properties of chitosan. The results demonstrated that these properties of chitosan were largely influenced by the action of gamma radiation. In addition, the fat binding capacity (FBC) of chitosan was found to be increased with increasing irradiation doses. In this work a thorough in-vivo investigation on mice was performed to examine FBC of irradiated chitosan (30–100 kGy) in animal bodies. Different groups of mice specimens were fed with γ-irradiated chitosan along with natural rodent chow and cheese as well as sufficient supply of water. The unconsumed lipid measured in feces was found to increase by 67% in mice whose diet included 100 kGy irradiated chitosan, relative to that nonirradiated chitosan. After twelve weeks of intimate observation, mice were sacrificed to examine triglyceride (TG) and total cholesterol (TC) content in mice blood. The results demonstrated that TG and TC values of mice fed with γ-irradiated chitosan were significantly lower than that of the control. All of these findings are expected to enhance the future research on irradiated chitosan to be used as potential fat reducer in human metabolism.

description: Interest in reducing the environmental impacts of building materials has prompted the development of biobased construction material alternatives from renewable resources. This study investigated the potential for animal-based protein derivatives to serve as low volatile organic compound (VOC), environmentally friendly adhesives for engineered wood products in temporary construction applications. First, the mechanical properties, namely bond strength, of virgin protein-based adhesives were characterized and compared to four commercially available adhesives. The flexural mechanical properties (e.g., flexural strength, flexural modulus of elasticity) of (a) two-ply glue-laminated composites and (b) laminated wood veneer composites manufactured using protein-based adhesives were characterized and compared to conventional engineered wood products, including oriented strand board (OSB), plywood, particleboard, and medium density fiberboard (MDF). In comparison to conventional adhesives and engineered wood products, the results suggest that protein-based adhesives have the potential to be used in construction as environmentally friendly wood adhesives and that protein-adhered laminated wood composites exhibit a potential to replace traditional engineered wood products, especially in formwork, scaffolding, and other temporary construction applications.

description: La actual organización territorial, social y política de las comunidades de la Gente de centro (que comprende principalmente grupos de las familias lingüísticas Witoto y Bora) ,es resultado de una historia de contacto desde el auge cauchero a principios del siglo XX hasta el reconocimiento de los territorios a finales del mismo siglo. Esta historia ha ocasionado desplazamientos, recomposición de los asentamientos y una creciente dependencia de los bienes de mercado. En este capítulo presentamos dos casos contrastantes de comunidades de Gente de centro: una comunidad con un patrón de asentamiento y organización marcado por la ideología de linajes autónomos con territorios separados, y con énfasis en la autonomía clánica a través de malocas: la comunidad nonuya de Peña Roja en el Medio río Caquetá; y una comunidad mayoritariamente uitoto, ubicada en las cercanías de Leticia, la comunidad del Kilómetro 11, con un patrón de asentamiento en forma de aldea, donde la maloca y la autoridad tradicional tienen una ubicación marginal

description: We investigated the influence of long-range transboundary transport (LRTT) on the aerosol concentrations in the Korean peninsula using the ground- and satellite-based remote sensing with back-trajectory calculations during the Korea-United States Air Quality (KORUS-AQ) campaign. Specifically, aerosol optical depth (AOD) observations from a geostationary satellite can directly provide the progression and evolution of aerosol plume transport. During high pollution cases in western Korea, we found the AOD enhancement over the Yellow Sea and east-central China, at maximum >200% over the pathway of LRTT compared to the mean condition. Particularly, high AOD in the Shandong peninsula appears coincidentally with the high AOD over South Korea in a day, revealing the strong influence of the east-central Chinese emission. Back-trajectory patterns remarkably capture the movement of high AOD bands detected by the geostationary satellite monitoring. LRTT cases through the inside of boundary layer at east-central China usually contribute to the high AOD in Korea, while air-masses above the boundary layer in north China and Mongolia do not much relate to the Korean pollution, showing the importance for both the direction and height of the air-mass movement. Travel speed is another significant factor to describe the LRTT effect. Despite the large effect of LRTT to both urban and rural sites in Korea, sometimes urban sites are more affected by the domestic emission when the air-mass travels shorter than ∼250 km per day, notifying that the effect of Korean domestic emission cannot be negligible as well. Our findings reveal that usage of geostationary satellite observations enables us to better evaluate the influence of LRTT on the local air pollution.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Shaping the animal body plan is a complex process that involves the spatial organization and patterning of the different germ layers. Recent advances in live imaging have started to unravel the cellular choreography underlying this process in mammals, however, the sequence of events transforming an unpatterned cell ensemble into structured territories is largely unknown. Here, using gastruloids -3D aggregates of mouse embryonic stem cells- we study the formation of one of the three germ layers, the endoderm. We show that the endoderm is generated from an epiblast-like homogeneous state by a three-step mechanism: (i) a loss of E-cadherin mediated contacts in parts of the aggregate leading to the appearance of islands of E-cadherin expressing cells surrounded by cells devoid of E-cadherin, (ii) a separation of these two populations with islands of E-cadherin expressing cells flowing toward the aggregate tip, and (iii) their differentiation into an endoderm population. During the flow, the islands of E-cadherin expressing cells are surrounded by cells expressing T-Brachyury, reminiscent of the process occurring at the primitive streak. Consistent with recent in vivo observations, the endoderm formation in the gastruloids does not require an epithelial-to-mesenchymal transition, but rather a maintenance of an epithelial state for a subset of cells coupled with fragmentation of E-cadherin contacts in the vicinity, and a sorting process. Our data emphasize the role of signaling and tissue flows in the establishment of the body plan.

description: Due to their positive environmental attributes and their performance, the use of bio-based insulation materials such as wood fibre, loose fill cellulose, hemp, flax and straw has been increasing in the construction industry across Europe. However, the current test method requirements to get technical approval do not take into account the real hygrothermal conditions in use. This research project aimed to model hygrothermal conditions of bio-based insulation materials (rigid, semi-rigid and loose-fill). The modelling of coupled thermal and humidity transfers was carried out with WUFI 2D software. Representative wall and roof were studied, with different end uses for insulation materials (outer, inner, distributed insulation). Four unfavourable French climates where studied (cold continental, humid oceanic, Mediterranean, mountain). Regarding modelled hygrothermal conditions and insulation material behaviour, two humidity use classes could be defined. An experimental design was carried out with wood fibre insulation material to assess the impact of temperature and relative humidity on the mould growth. An innovative mould test was developed with a quantitative assessment of mould growth. Finally, corroborating these two parts, this project gave to the manufacturers of biobased insulation materials the option to highlight natural durability of their products, testing them in an environment that fits with the real hygrothermal conditions in use.

Testing lepton universality with ep and μp elastic scattering in the MUSE experiment
Creators: name: Lin, Wan (Win)
Publisher: name: No Publisher Supplied
Year: 2024

description: The MUon proton Scattering Experiment (MUSE) at the PiM1 beam line of the Paul Scherrer Institute in Villigen, Switzerland, simultaneously measures the elastic scattering cross sections of electrons and muons from a liquid hydrogen target. The main objective of the experiment is to determine the charge radius of the proton by extrapolating the Q2 dependence of the electric form factor as Q2 → 0 to resolve the proton radius puzzle. The proton radius puzzle arose from the 5σ discrepancy between recent muonic hydrogen spectroscopy measurements and electron-proton scattering measurements. New studies and measurements have been done since the puzzle was established, yet the discrepancy remains unresolved. MUSE will be the first high precision experiment to measure ep and μp elastic scattering at the same time in the same apparatus, and directly compare the differences between ep and μp interactions. By comparing the cross sections, MUSE will explore different possible explanations for the proton radius puzzle, including two photon exchange and lepton universality violation.Lepton universality, as defined by the Standard Model states that all lepton interactions are the same except for trivial mass differences. The recent muon g − 2 experiment from BNL and FermiLab raised the possibility of the violation of lepton universality, which is a potential solution to the proton radius puzzle. MUSE will test lepton universality by comparing the elastic scattering cross sections of ep and μp for both negative and positively charged leptons. In this dissertation, a study of this topic will be presented with blinded preliminary data from the 2023 beam time at momenta of ±115 MeV/c and ±160 MeV/c. The discussion will involve an overview of the proton radius puzzle, the past and recent effort on the violation of lepton universality search, and the details of the MUSE experimental setup. Analysis along with detector calibration that lead to the preliminary result will be introduced. The preliminary data shows that the ratio of the measured electron proton cross section to the muon proton cross section agrees with prediction at the level of the blinding range. While further analysis is ongoing, current results demonstrate the method and ability to test lepton universality at MUSE.

description: The hydrogen bond (HB) strength, geometry optimization, vibrational frequencies and several well-established indices of aromaticity in 1,1,1-trifluoro-4-mercaptobut-3-ene-2-thione and its 15 derivatives in two positions, R1 and R2, have been investigated by means of the density functional theory (DFT) method with 6-311++G** basis set in the gas phase. The obtained results show that the HB strength is mainly governed by resonance variations inside the chelate ring induced by the substituent groups. The following substituents have been taken into consideration: NO2, SCF3, Ph, PhOCH3, SCOCH3, CH2OCH3 and CH2OH. The strongest S–H···S HBs belong to PhOCH3-substituted system in both positions, whereas NO2 and H substitutions in R1 and R2 positions, respectively, produce the weakest S–H···S hydrogen bridges. The excited-state properties of intramolecular hydrogen bonding in substituted systems have been investigated theoretically using the time-dependent DFT method. Natural bond orbital analysis is also performed for a better understanding of the nature of intramolecular interactions. The electron density and Laplacian (∇2ρ) properties, estimated by atoms in molecule calculations, indicate that the H···S bond possesses low ρ, positive ∇2 ρ and HC<0, which are in agreement with the partially covalent character of HBs.

description: Significantly decreasing energy consumption in buildings requires more air-tight construction combined with much higher insulation levels. A potential unintended consequence of this approach has been deterioration in the indoor air quality, resulting from significantly reduced ventilation rates and the accumulation of airborne pollutants, and this has proven to be a bottleneck to successful implementation of legislation. The use of natural bio-based insulation materials has increased in recent years, largely driven by concerns over the embodied energy and whole-life environmental impact of insulation materials. This has led to their increased use, typically within breathable wall constructions. A breathable wall construction allows the insulation material to directly contribute to the indoor air quality. Volatile Organic Compounds (VOCs) having boiling points within the range 60-280 °C contribute to the indoor air contamination in buildings, and at certain concentrations can contribute to building-related illnesses. This paper presents some findings from the early stages of a phased experimental study to explore use of bio-based insulation materials, including hemp-lime and sheep’s wool, to reduce VOCs from the room atmosphere. There are many different volatile organic compounds and this study will consider the Total Volatile Organic Compound (TVOC) emissions expressed as toluene, as well as the formaldehyde emissions separately. Insulation specimens with nominal dimensions 200 x 60 x 50 mm were prepared and placed in horizontally mounted cylindrical chambers. Air maintained at 23 °C (±2 °C) and 50 % (±5 %) RH was fed in coaxially to one end of the cylinder. The exhaust air was sampled for VOCs and for formaldehyde following 3 and 28 day of exposure. The results of this paper will help inform the design of holistic indoor environments that consider more than just the hygrothermal properties of insulation materials.

description: No one likes to be wrong. Previous research has shown that participants may underweight information incompatible with previous choices, a phenomenon called confirmation bias. In this paper, we argue that a similar bias exists in the way information is actively sought. We investigate how choice influences information gathering using a perceptual choice task and find that participants sample more information from a previously chosen alternative. Furthermore, the higher the confidence in the initial choice, the more biased information sampling becomes. As a consequence, when faced with the possibility of revising an earlier decision, participants are more likely to stick with their original choice, even when incorrect. Critically, we show that agency controls this phenomenon. The effect disappears in a fixed sampling condition where presentation of evidence is controlled by the experimenter, suggesting that the way in which confirmatory evidence is acquired critically impacts the decision process. These results suggest active information acquisition plays a critical role in the propagation of strongly held beliefs over time.

Mercenaries ought to be contextualized among the diplomatic strategies by which Greek cities sought to remain vital, and by which some Cretan cities even succeeded up until the Roman conquest in 67 BCE. Hellenistic Cretan mercenaries need not be considered as the output of circumstances idiosyncratic to Crete, such as economic crisis, a demand for a brand of warfare unique to the island, or an exceptional culture of violence, but rather as part of a Mediterranean-wide cultural phenomenon. Furthermore, the most secure way to identify Hellenistic Cretan mercenaries is through unambiguous labels in textual sources. The study primarily uses close readings of literary and epigraphic texts to analyze the terminology for defining Cretan mercenaries and to better understand contemporary Hellenistic portrayals of and attitudes towards Crete and Cretans, especially those in Polybius’ Histories. Chapter 1 observes that the Greek term Krēs, often taken to indicate Cretan mercenaries from Crete, could identify a person’s origin and/or a specialized type of fighter, depending on context; but it was not always an unambiguous indicator of both, i.e., a Cretan mercenary from Crete. Examining material, literary, and epigraphic evidence, Chapters 2 and 3 maintain that warfare on Crete reflected mainline practices in the Greek world. Although Krētes fighters were undoubtedly specialists, their context was hegemonic (i.e., royal, league, Roman) war, not the small interpolis warfare found on Crete. Chapter 4 first posits that Polybius uses Crete as a model to illustrate for his readers the symptoms of ailing political systems; it then applies this model to Polybius’ historical accounts of Crete, concluding that Polybius criticizes how foreign aid enabled and sustained violence amongst Cretan cities. Chapter 5 offers a close reading of mercenary recruitment clauses in inscribed alliances and corroborates Polybius’ observation: Cretan cities used alliances to create relationships that lasted beyond the immediate circumstances of alliance. Mercenaries were one means by which cities could offer substantive support for these relationships and, in turn, receive crucial aid in times of need

description: Materials from agroresources (granulates and fibres) are more and more developed in order to use renewable resources and to limit carbon footprint. These materials are used in many applications like building constructions. They are exposed to very high variations of temperature and humidity… In some cases, these conditions may be favorable for the development of microorganisms. Vegetal granulates or fibres are composed by a set of polysaccharides whose nature and function are different. Some microorganisms may use this sugar for growth. Microorganisms and more precisely mold growth may alter materials by consumption of constituent and induce health damage due to the liberation of spores in the atmosphere. In our study, we focus on the impact of microorganisms on agroresource materials. First, we only concentrate on mold growth on flax fibres. We have tested the evolution of chemical composition of lignocellulosic materials.

description: International trade, the major area of engagement in Nigeria's economy, heavily depends on the performance and efficiency of financial institutions (especially Deposit Money Banks [DMBs]) in the discharge of trade transactions. The DMBs engage in international trade via providing financial services, including letters of credit, trade finance loans, and foreign exchange services required by businesses to import and export goods. At the same time, a host of structural challenges including foreign exchange instability, high cost-to-serve, regulatory encumbrances, and cyber threats usually hike the inefficiencies encountered by DMBs in trade finance. The paper appraises the efficiency of DMBs in international trade finance in Nigeria evaluating their performance in international trade of goods over periods carving an opportunity during and after the pandemic, including analyzing the nature of trade finance provisioned by DMBs, while concurrently reflecting on salient factors inhibiting DMBs' efficiency in serving businesses' trade finance needs in Nigeria. DMBs perform painstakingly well in the international trade ecosystem, but great challenges potentially impede their ability to serve well while presenting practical opportunities towards improved efficiency and growth. The research distinguishes the performance of DMBs from those of the banks in competing emerging markets, thereby providing lessons and best- practice examples that can be borrowed for better service provision. It also discusses the role of the Central Bank of Nigeria in the sector and outlines crucial considerations such as regulations' impact and implications on banking performance and efficiency in achieving and supporting trade for Nigerian businesses

description: The Unique Grid Cell Identification (UGCI) system was created using the Croatian cartographic map grid system as a basis for development. A short description of the Croatian map grid system is therefore provided. Cartographic map nomenclature is used to uniquely identify map sheets; e.g. grid cells. Nonetheless, because such nomenclature uses alpha-numeric and special characters and complex coding/decoding systems, it is not well suited for use with GIS, databases, internet services and other Information and Communications Technologies applications. UGCI has been developed to uniquely identify all spatial grid cells, no matter their scale. It should enable easy connections with spatial grid cell identifier systems of other Spatial Data Infrastructure communities, such as ecology, geology, meteorology, etc. Easier identification and use of spatial grid cells contributes to the interoperability of maps and other spatial data. Map is cowering Croatian grid area in the scale 1:1 800,000. It is representing grids scales from 1:250,000 to 1:5000.

description: Everyone now knows that the building industry accounts for 43% of energy consumption and 25% of greenhouse gas emissions. It thus constitutes one of the key objectives in the pursuit of the "Factor 4" issues in 2050. The thermal insulation defects of buildings and mistreatment of airtightness problems are the main causes low energy performance of the built French park. The fight against energy waste therefore passes deals with the thermal insulation of heated buildings. The thermal insulation performances are firstly determined by their thermal conductivity and the physical quantity characterizing the behaviour of materials during the heat transfer by conduction. With an average thermal conductivity of 0.023 W/m.K, polyurethane foam remains very good for building insulation. The advantage of this material therefore results in a gain of living space. Indeed for a given heat resistance, the thickness of material required is lower than for the homologous. However, PU foams are generally expensive especially because of the presence of fossil compounds as well as adverse effects on the environment and health (discharge of volatile organic compounds VOCs). In 2007, the French chemical industry is committed to use by 2017, 15% of bio based raw materials and diversify its industrial resources used (agricultural resources, especially non-food processes, and lignocellulosic waste and coproducts). However, only 8% of raw materials of the French chemical industry are renewable. Polyurethane foams are generally composed of two main compounds: Polyols, and isocyanate, the both from fossils resources. There is today part of a solution dealing with bio polyols from rape seed oils, but in most of case too much expensive for this industry. CNSL (Cashew Nut Shell Liquid) is a co-product of cashew nut exploitation. It is a kind of vegetal oil mainly composed of anacardic Acid and cardanol. This oil may be a very performant and low coast raw material ($ 300/ton) for polyol production to substitute fossil polyols in Polyurethane composition. CoDEM is today developing new bio based expanded foam with CNSL to reach a target thermal conductivity near 0,025 W/m.K This communication may explains the first part of our works substituting polyols and first results measured in our laboratory.
