description: Excited state intramolecular proton transfer (ESIPT) core containing, two series of benzothiazole and benzimidazole based fluorescent acid azo dyes were synthesized. These dyes analyzed and confirmed by 1H NMR, 13C NMR, FT-IR and elemental analysis. Spectral characteristics of these dyes studied in different polarity solvents showed Stokes shift 2888–4678 cm–1 and 2167–4837 cm–1 for benzimidazole and benzothiazole series, respectively. Wool and silk fabric dyed with these dyes, shows 92.1–94.4% (benzimidazole) and 92.4–95.1% (benzothiazole) percentage exhaustion on wool. The dyed substrate evaluated for UV rays protective properties, antibacterial activity light, wash and rubbing fastness. Synthesized dyes show significant antibacterial activity when tested by Agar-well diffusion test against Staphylococcus aureus (Gram positive), Klebsiella pneumonia (Gram negative) bacteria.

description: In this paper, we consider a general twisted-curved space-time hosting Dirac spinors and we take into account the Lorentz covariant polar decomposition of the Dirac spinor field: the corresponding decomposition of the Dirac spinor field equation leads to a set of field equations that are real and where spinorial components have disappeared while still maintaining Lorentz covariance. We will see that the Dirac spinor will contain two real scalar degrees of freedom, the module and the so-called Yvon-Takabayashi angle, and we will display their field equations. This will permit us to study the coupling of curvature and torsion respectively to the module and the YT angle.

Biaxial-stress driven tetragonal symmetry breaking in and high-temperature ferromagnetic semiconductor from half-metallic CrO2

description: It is highly desirable to combine the full spin polarization of carriers with modern semiconductor technology for spintronic applications. For this purpose, one needs good crystalline ferromagnetic (or ferrimagnetic) semiconductors with high Curie temperatures. Rutile CrO$_2$ is a half-metallic spintronic material with Curie temperature 394 K and can have nearly-full spin polarization at room temperature. Here, we find through first-principles investigation that when a biaxial compressive stress is applied on rutile CrO$_2$, the density of states at the Fermi level decreases with the in-plane compressive strain, there is a structural phase transition to an orthorhombic phase at the strain of -5.6\%, and then appears an electronic phase transition to a semiconductor phase at -6.1\%. Further analysis shows that this structural transition, accompanying the tetragonal symmetry breaking, is induced by the stress-driven distortion and rotation of the oxygen octahedron of Cr, and the half-metal-semiconductor transition originates from the enhancement of the crystal field splitting due to the structural change. Importantly, our systematic total-energy comparison indicates the ferromagnetic Curie temperature remains almost independent of the strain, near 400 K. This biaxial stress can be realized by applying biaxial pressure or growing the CrO$_2$ epitaxially on appropriate substrates. These results should be useful for realizing full (100\%) spin polarization of controllable carriers as one uses in modern semiconductor technology.

description: To assist the design of novel, highly efficient molecular junctions, a deep understanding of the precise charge transport mechanisms through these devices is of prime importance. In the present contribution, we describe a procedure to investigate spatially-resolved electron transport through a nanojunction from first principles, at the example of a nitro-substituted oligo-(phenylene ethynylene) covalently bound to graphene nanoribbon leads. Recently, we demonstrated that the conductivity of this single-molecule-graphene-nanoribbon junction can be switched quantitatively and reversibly upon application of a static electric field in a top gate position, in the spirit of a traditional field effect transistor [J. Phys. Chem. C, 2016, 120, 28808-28819]. The propensity of the central oligomer unit to align with the external field was found to induce a damped rotational motion and to cause an interruption of the conjugated $π$-system, thereby drastically reducing the conductance through the nanojunction. In the current work, we use the driven Liouville-von-Neumann (DLvN) approach for time-dependent electronic transport calculations to simulate the electronic current dynamics under time-dependent potential biases for the two logical states of the nanojunction. Our quantum dynamical simulations rely on a novel localization procedure using an orthonormal set of molecular orbitals obtained from a standard density functional theory calculation to generate a localized representation for the different parts of the molecular junction. The transparent DLvN formalism allows us to directly access the density matrix and to reconstruct the time-dependent electronic current density, unraveling unique mechanistic details of the electron transport.

description: This paper gives foundational results for the application of quasi-stationarity to Monte Carlo inference problems. We prove natural sufficient conditions for the quasi-limiting distribution of a killed diffusion to coincide with a target density of interest. We also quantify the rate of convergence to quasi-stationarity by relating the killed diffusion to an appropriate Langevin diffusion. As an example, we consider in detail a killed Ornstein--Uhlenbeck process with Gaussian quasi-stationary distribution.

Constraining high-energy neutrino emission from choked jets in stripped-envelope supernovae

description: There are indications that $γ$-ray dark objects such as supernovae (SNe) with choked jets, and the cores of active galactic nuclei may contribute to the diffuse flux of astrophysical neutrinos measured by the IceCube observatory. In particular, stripped-envelope SNe have received much attention since they are capable of producing relativistic jets and could explain the diversity in observations of collapsar explosions (e.g., gamma-ray bursts (GRBs), low-luminosity GRBs, and Type Ibc SNe). We use an unbinned maximum likelihood method to search for spatial and temporal coincidences between Type Ibc core-collapse SNe, which may harbor a choked jet, and muon neutrinos from a sample of IceCube up-going track-like events measured from May 2011-May 2012. In this stacking analysis, we find no significant deviation from a background-only hypothesis using one year of data, and are able to place upper limits on the total amount of isotropic equivalent energy that choked jet core-collapse SNe deposit in cosmic rays ${\mathcal E}_{\rm cr}$ and the fraction of core-collapse SNe which have a jet pointed towards Earth $f_{\rm jet}$. This analysis can be extended with yet to be made public IceCube data, and the increased amount of optically detected core-collapse SNe discovered by wide field-of-view surveys such as the Palomar Transient Factory and All-Sky Automated Survey for Supernovae. The choked jet SNe/high-energy cosmic neutrino connection can be more tightly constrained in the near future.

Effect of Sugarcane Bagasse Ash on bagasse fiber reinforced concrete properties
Creators: name: Dawit Abate
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2020
Subjects: Bagasse fiber reinforced concrete, Bagasse ash, Fresh property, Harden property, and Economic analysis

description: As one of most consumed resources in the planet, different new technologies are highly being
 implemented recently to enhance both fresh and harden properties of concrete. Insertion of fibers,
 use of admixtures and utilization of substituting materials are among the technologies being
 exercised to create special concrete contributing to improve strength and setting time properties
 which in turn helps to reduce environmental and economic impacts faced while working with
 concrete. Bagasse fiber-reinforced concrete is one type of special concrete that can be made by
 way of inserting well-prepared bagasse fiber in to a concrete mix to enhance the tensile properties
 of concrete. But researchers found that, its utilization reduces compressive strength although the
 condition might be adjusted using a mineral admixture. The general objective of this study was to
 assess effects of sugarcane bagasse ash on fresh and harden properties of bagasse fiber-reinforced
 concrete. This experimental study carried out preparing five different mixes to check compressive,
 split tensile and flexural strength tests after each 7, 14 and 28 days of curing. For this study, cement
 replaced by weight with bagasse ash in 5%, 10% and 15%. The effects of each percentage mix
 have finally been compared with FRC mixture with constant 0.5% sugarcane bagasse and
 conventional C- 35Mpa concrete. Economic analysis for best mix has also been one of the
 objectives for study undertaken.
 Result of the research shows that, among fiber reinforced concrete mixtures, maximum strength
 of harden concrete achieved from M2 i.e. a mix with 5% replacement level and incorporation of
 0.5% bagasse fiber. based on the investigation, 19.6%, 6.05% and 6.67% more strength have
 succeeded for computed compressive, split tensile and flexural strength tests respectively at 28
 days of curing by this mix relative to control FRC mix with only 0.5% bagasse fiber content.
 Similarly, the tensile and flexural strength of M2 shows an increment resulting further 15.27% and
 13.33% computed value at 28 days of curing with respect to M1 despite a slight reduction in
 compressive strength as compared with conventional concrete M1. And based on economic
 comparison, preparation of ordinary concrete mixture takes additional 0.61% increase in price than
 cost incurred to prepare B.F.R.C. with 5% bagasse ash to replace cement.

description: The aggregation of polycyclic aromatic compound (PAC) molecules is sensitive to the solvent they are dissolved or suspended in. By using both dynamic light scattering and diffusion-ordered nuclear magnetic resonance spectroscopy, in combination with molecular dynamics simulations, the effect of chemical structure on the aggregation of PACs in both aromatic and alkane solvents were systematically investigated. A suite of triphenylene-based PACs offers a robust platform to understand the driving forces of aggregation mechanism across both nanometer and micrometer scales. Both the configuration, either parallel or otherwise, and the arrangement, whether compact or loose, of molecules in their aggregates are determined by a fine balance of different interactions such as those between the polar groups, π–π interactions between the aromatic cores, steric hindrance induced by the side chains, and the degree of solvation. These results suggest that molecular architecture is the major factor in determining how the model compounds aggregate. The shift from aromatic to aliphatic solvent only slightly increases the likelihood of aggregation for the model compounds studied while subtle differences in molecular architecture can have a significant impact on the aggregation characteristics.

description: Bitcoin is a popular cryptocurrency that records alltransactions in a distributed append-only public ledger calledblockchain. The security of Bitcoin heavily relies on the incentive-compatible proof-of-work (PoW) based distributed consensus pro-tocol, which is run by network nodes called miners. In exchangefor the incentive, the miners are expected to honestly maintainthe blockchain. Since its launch in 2009, Bitcoin economy hasgrown at an enormous rate, and it is now worth about 170 billions of dollars. This exponential growth in the market valueof Bitcoin motivates adversaries to exploit weaknesses for profit,and researchers to discover new vulnerabilities in the system,propose countermeasures, and predict upcoming trends.In this paper, we present a systematic survey that covers thesecurity and privacy aspects of Bitcoin. We start by presenting anoverview of the Bitcoin protocol and its major components alongwith their functionality and interactions within the system. Wereview the existing vulnerabilities in Bitcoin and its underlyingmajor technologies such as blockchain and PoW based consensusprotocol. These vulnerabilities lead to the execution of varioussecurity threats to the normal functionality of Bitcoin. Wethen discuss the feasibility and robustness of the state-of-the-art security solutions. Additionally, we present current privacyand anonymity considerations in Bitcoin and discuss the privacy-related threats to Bitcoin users along with the analysis of theexisting privacy-preserving solutions. Finally, we summarize thecritical open challenges and suggest directions for future researchtowards provisioning stringent security and privacy techniquesfor Bitcoin.

description: A moving mesh finite element method is studied for the numerical solution of a phase-field model for brittle fracture. The moving mesh partial differential equation approach is employed to dynamically track crack propagation. Meanwhile, the decomposition of the strain tensor into tensile and compressive components is essential for the success of the phase-field modeling of brittle fracture but results in a non-smooth elastic energy and stronger nonlinearity in the governing equation. This makes the governing equation much more difficult to solve and, in particular, Newton's iteration often to fail to converge. Three regularization methods are proposed to smooth out the decomposition of the strain tensor. Numerical examples of fracture propagation under quasi-static load demonstrate that all of the methods can effectively improve the convergence of Newton's iteration for relatively small values of the regularization parameter but without comprising the accuracy of the numerical solution. They also show that the moving mesh finite element method is able to adaptively concentrate the mesh elements around propagating cracks and handle multiple and complex crack systems.

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: We show a few nontrivial extensions in the classical Adams spectral sequence. In particular, we compute that the 2-primary part of $π_{51}$ is $\mathbb{Z}/8\oplus\mathbb{Z}/8\oplus\mathbb{Z}/2$. This was the last unsolved 2-extension problem left by the recent works of Isaksen and the authors (\cite{Isa1}, \cite{IX}, \cite{WX1}) through the 61-stem. The proof of this result uses the $RP^\infty$ technique, which was introduced by the authors in \cite{WX1} to prove $π_{61}=0$. This paper advertises this method through examples that have simpler proofs than in \cite{WX1}.

The SnCl2 catalyzed reaction of 2-amino-4H-chromen-4-one with 2-benzylidenemalononitriles provides the corresponding substituted aza-anthraquinone analogs via a Michael addition–elimination followed by intramolecular cyclization in good to excellent yields under mild reaction conditions. Furthermore, the synthesized compounds 3a–3l were analyzed for their preliminary photo physical properties (absorption and emission spectra) in CHCl3 at 100 μM. Among the compounds (3a–3l), the compounds 3c and 3b exhibited larger emission band maxima toward bathochromic shifts at 488 nm and 468 nm, respectively.

Um zu untersuchen, welche Möglichkeiten digitale Partizipationsmöglichkeiten und -plattformen den Jungen bieten, wurden im Jahr 2020 an der Fachhochschule Graubünden drei Gruppendiskussionen durchgeführt, die ein Teilprojekt einer Studie zum Thema „Jugend, politische Partizipation und Digitalisierung“ darstellen. In zwei Gruppendiskussionen, je eine mit deutschsprachigen und französischsprachigen Jugendlichen und jungen Erwachsenen, wurde untersucht, welche Anforderungen und Erwartungen die Zielgruppe an digitale Partizipationsformen und -möglichkeiten haben. In einer weiteren Diskussionsrunde mit Expertinnen und Experten aus den Bereichen Jugendarbeit und Civic Tech wurden bestimmte Aspekte aus den ersten beiden Gruppendiskussionen näher erörtert.

description: New quinazolinone and fused quinazoline derivatives are prepared from the reaction of 3,1-benzoxazine-3(4H)-one with different amines. Treatment of 3,1-benzoxazinone 3 with hydrazine hydrate afforded 3-amino-quinazolinone derivative 5 which then used as a key synthesis for different Schiff base compounds 6-8. Synthesis of new fused quinazoline derivatives 9, 10 are achieved from the reaction of 3,1-benzoxazinone with cyanoacetohydrazide or thiocarbohydrazide. The chemical structures of the new synthesized compounds were elucidated based on their spectroscopic analysis. Antimicrobial activities of the designated compounds were studied in vitro toward different pathogenic microbes. Drug-likeness and ADMET properties of the new synthesized compounds were calculated to predict the pre-study of clinical phases as drug molecule, and most of the new compounds fit Lipinski rule and have good bioavailability. Molecular docking studies of all new synthesized compounds were performed into the active site of different macromolecules including bacterial and fungus species and exhibiting good binding energy extended from −5.20 to −10.35 Kcal/mol.

description: A new series of 3-(5-aryl-1-phenyl-1H-pyrazol-3-yl)-5-aryl-1,2,4-oxadiazole (9a–x) have been synthesized by a reaction of 5-aryl-N′-hydroxy-1-phenyl-1H-pyrazole-3-carboximidamide (7a–d) with substituted methyl benzoate (8a–f). The newly synthesized 3-(5-aryl-1-phenyl-1H-pyrazol-3-yl)-5-aryl-1,2,4-oxadiazole (9a–x) derivatives were characterized by spectroscopic techniques and screened for in vitro antibacterial activity against Gram-positive bacterial strains Bacillus subtilis (NCIM 2063), Staphylococcus albus (NCIM 2178). Gram-negative bacterial strains Escherichia coli (NCIM 2574), it was noticed that compounds 9h, 9i, and 9j in which R = 4-Cl and R1 = 2-Cl/4-Cl or 4-CH3 showed good activity against B. subtilis with MIC 31.25 μg/mL against standard S. albus having MIC 7.81 μg/mL. Proteus mirabilis (NCIM 2388) and in vitro antifungal activity against Aspergillus niger (ATCC 504) Candida albicans (NCIM 3100). 3-(5-Aryl-1-phenyl-1H-pyrazol-3-yl)-5-aryl-1,2,4-oxadiazole derivatives like compound 9a (R = H, R1 = 2-Cl), 9b (R = H, R1 = 2-Cl), 9d (R = H, R1 = 4-Cl), and 9k (R = 4-Cl, R1 = 4-OCH3) showed good activity against A. niger with MIC 31.25 µg/mL, which are comparable to standard drug ravuconazole having MIC 31.5 µg/mL. Compounds 9h (R = 4-Cl, R1 = 2-Cl) and 9j (R = 4-Cl, R1 = 4-CH3) showed activity against A. niger with MIC 7.81 µg/mL which is comparable to standard drug Fluconazole having MIC 7.81 µg/mL and fourfold more activity with respect to drug Ravuconazole. The antibacterial activity of 3-(5-aryl-1-phenyl-1H-pyrazol-3-yl)-5-aryl-1,2,4-oxadiazole (9a–x) derivatives led to the conclusion that these scaffolds could aid in the creation of lead drugs to treat microbial infection.

Só quem ama assim as aves/traz o sol todo na mão: uma leitura do conto «Homenagem ao Papagaio Verde», de Jorge de Sena
Creators: name: Bagão, Teresa
Publisher: name: Forma Breve
Year: 2004

description: Na infância do narrador, o Papagaio Verde, ave tropical em exílio forçado num triste andar lisboeta, assume-se como um verdadeiro amigo, partilhando ambos a raiva e o desprezo pelos adultos, carcereiros dos voos da vontade e da imaginação. Num espaço de clausura asfi xiante, a música tocada ao piano pelo narrador-criança abre-lhe possibilidades de comunicação e permite-lhe a momentânea libertação, sempre na companhia do Papagaio Verde, indomável duplo do protagonista.

description: Informational dependence between statistical or quantum subsystems can be described with Fisher matrix or Fubini-Study metric obtained from variations of the sample/configuration space coordinates. Using these non-covariant objects as macroscopic constraints we consider statistical ensembles over the space of classical probability distributions or quantum wave-functions. The ensembles are covariantized using dual field theories with either complex or real scalar fields identified with complex wave-functions or square root of probabilities. We argue that a full space-time covariance on a field theory side is dual to local computations on the information theory side. We define a fully covariant information-computation tensor and show that it must satisfy conservation equations. Then we switch to a thermodynamic description and argue that the (inverse of) space-time metric tensor is a conjugate thermodynamic variable to the ensemble-averaged information-computation tensor. In the equilibrium the entropy production vanishes and the metric is not dynamical, but away from equilibrium the entropy production gives rise to an emergent dynamics of the metric. This dynamics can be described by expanding the entropy production into products of generalized forces (derivatives of metric) and conjugate fluxes. Near equilibrium these fluxes are given by an Onsager tensor contracted with generalized forces and on the grounds of time-reversal symmetry the Onsager tensor is expected to be symmetric. We show that a particularly simple and highly symmetric form of the Onsager tensor gives rise to the Einstein-Hilbert term. This proves that general relativity is equivalent to a theory of non-equilibrium (thermo)dynamics of the metric which is expected to break down far away from equilibrium where the symmetries of the Onsager tensor are to be broken.

Swiss Farmers' Views on Cover Crop Practice and Climate Change
Creators: name: Lötscher, Jasmine
Publisher: name: Zenodo
Year: 2024

description: This thesis investigates Swiss farmers' views on cover crop practices and climate change using a mixed-methods approach, integrating Q-Methodology and qualitative interviews. Cover crops offer multiple potential benefits for increasing the sustainability of agricultural systems, particularly in the context of climate change. Furthermore, Swiss legislation on subsidies is already mandating their implementation. However, understanding how these practices are applied in real-world farming and identifying the incentives for farmers to adopt cover crops are critical for informing policy and promoting sustainable agriculture. This study provides insights into farmers' goals, motivations, and challenges regarding cover crop use and climate change adaptation. Three distinct farmer viewpoints emerged from the analysis: regenerative farmers, who prioritize soil health; economic farmers, who emphasize cost-efficiency, immediate effects on subsequent crops and often use cover crops primarily for forage; and sustainable-conventional farmers, who balance forage production with environmental considerations. The research also highlights differing preferences for cover crop types among these groups. Regenerative farmers favor green manure crops to enhance soil health, while economic farmers tend to prioritize fodder crops for livestock feed.Farmers exhibited diverse views on climate change, generally acknowledging more negative than positive impacts, such as increased weather extremes. No one expressed climate change denial. However, most were not overly concerned about the immediate effects on their own farms. Despite the challenges, many farmers demonstrated optimism and a proactive attitude, with cover crops playing an essential role as an adaptation measure to climate change. Other key adaptation strategies identified include the introduction of drought-resistant crop varieties and the implementation of advanced technologies. Additionally, the study uncovered further emerging challenges for Swiss agriculture during the interviews, emphasizing the need to integrate these concerns into the broader discourse on agricultural sustainability. Overall, this research provides a valuable foundation for understanding the complex decisionmaking processes of Swiss farmers regarding the use of cover crops and their adaptation to climate change. These findings can serve as a basis for more targeted policy decisions and communication strategies, ultimately promoting more sustainable agricultural practices.

description: Nonequilibrium dynamics in correlated materials has attracted attention due to the possibility of characterizing, tuning, and creating complex ordered states. To understand the photoinduced microscopic dynamics, especially the linkage under realistic pump conditions between transient states and remnant elementary excitations, we performed nonperturbative simulations of various time-resolved spectroscopies. We used the Mott antiferromagnetic insulator as a model platform. The transient dynamics of multi-particle excitations can be attributed to the interplay between Floquet virtual states and a modification of the density of states, in which interactions induce a spectral weight transfer. Using an autocorrelation of the time-dependent spectral function, we show that resonance of the virtual states with the upper Hubbard band in the Mott insulator provides the route towards manipulating the electronic distribution and modifying charge and spin excitations. Our results link transient dynamics to the nature of many-body excitations and provide an opportunity to design nonequilibrium states of matter via tuned laser pulses.
