Abstract:

The mount project is extremely important to ensure good isolation of equipment that generates vibration, be it a motor, a hydraulic pump, a compressor, among others. For the mount project, the positioning of the mount and its stiffness are very important characteristics, as they influence the independence of the moving directions and also the isolation performance. For the application of mount project in powertrains, this is not different, as the high isolation performance of the mount is extremely important to ensure the reduction of vibration transmission from the powertrain and, for this, t

Abstract:

AbstractLogical inferentialism claims that the meaning of the logical constants should be given, not model-theoretically, but by the rules of inference of a suitable calculus. It has been claimed that certain proof-theoretical systems, most particularly, labelled deductive systems for modal logic, are unsuitable, on the grounds that they are semantically polluted and suffer from an untoward intrusion of semantics into syntax. The charge is shown to be mistaken. It is argued on inferentialist grounds that labelled deductive systems are as syntactically pure as any formal system in which the rul

AbstractThis research aims to characterize the mineralogical and crystal-chemical purity of two samples of natural talc (BTT6, BTT7) from the occurrence ‘Ecole1’ in the deposit of Minzanzala, southwest Gabon. X-ray diffraction and modal-composition calculations demonstrated the presence of quartz and Al–Fe-bearing phases (kaolinite and/or chlorite and/or Al–Fe oxyhydroxides) as accessory minerals in both ores. In contrast, the chemical and spectroscopic characterization of the talc component revealed remarkable chemical purity expressed by very low Fe contents. According to these results, the

Abstract:

Utilizing the phase-matching conditions of inter-modal four-wave mixing in an elliptical-core few-mode fiber supporting three non-degenerate modes, we experimentally demonstrate schemes for generating orbital-angular-momentum (OAM)-entangled photon pairs with high mode purity and for achieving highly mode-selective frequency conversion of beams in OAM-compatible (LP11a, LP11b) mode basis. These techniques expand the toolbox for using OAM modes in both classical and quantum communications and information processing.

Near-unstable cavities hold promise for reducing thermal noise in next-generation gravitational wave detectors and for enhancing light–matter interactions in quantum electrodynamics.

Modal testing is routinely applied to tyres for the identification of structural parameters and prediction of their vibration response to excitations. The present work focuses on the more demanding case of modal testing with the aim of constructing a full mathematical model of a tyre, appropriate for use in a generic time-based simulation. For this purpose, the less common free–free boundary condition is employed for the wheel, while the tyre belt is excited in all three directions, namely radial tangential and lateral.

Abstract:

A methodology was implemented for purifying peptides in one chromatographic run via solid-phase extraction (SPE), reverse phase mode (RP), and gradient elution, obtaining high-purity products with good yields. Crude peptides were analyzed by reverse phase high performance liquid chromatography and a new mathematical model based on its retention time was developed in order to predict the percentage of organic modifier in which the peptide will elute in RP-SPE. This information was used for designing the elution program of each molecule. It was possible to purify peptides with different physicoc

This study describes the purification and preparation of tricin (5, 7, 4-trihydroxy-3, 5-dimethoxyflavone) from Carex Meyeriana Kunth via adsorption and desorption using macroporous resins and high-performance liquid chromatography. Six resins were tested to evaluate the static adsorption and desorption capacities. The HPD-300 resin was selected as the adsorption material to enrich tricin because of its suitable adsorption and desorption capacities. Adsorption thermodynamics and kinetics were studied on HPD-300 resin, and the results agreed with the Langmuir model and quasi-second-order kineti

Abstract:

We estimate a model of illicit drugs markets using data on purchases of crack cocaine. Buyers are searching for high-quality drugs, but they determine drugs' quality (i.e., their purity) only after consuming them. Hence, sellers can rip off first-time buyers or can offer higher-quality drugs to induce buyers to purchase from them again. In equilibrium, a distribution of qualities persists. The estimated model implies that if drugs were legalized, in which case purity could be regulated and hence observable, the average purity of drugs would increase by approximately 20 percent and the dispersi

Solvent extraction (SX) is a widely used separation and purification technique in hydrometallurgy, enabling the selective transfer of target metal ions between aqueous and organic phases. The process relies on chemical equilibrium and the interaction between metal ions and extractants in the organic phase. The free ligand (FL) model enhances the understanding of SX by focusing on the availability of free ligands in the organic phase, a critical factor influencing extraction efficiency and purity.

Abstract:

Protein purification is essential in life sciences and biomanufacturing. Tag-mediated protein affinity chromatography (AC) enables the preparation of recombinant proteins with medium to high purity. However, traditional AC methods often require expensive resins and additional tag removal steps. Here, we introduce a purification method for proteins with authentic N-termini based on reusable SpyDock-modified epoxy resin and a pH-inducible self-cleavage intein. This method was validated using SpyTag002-fused red fluorescent protein (RFP) and applied to purify three model proteins: glutathione S-t

With distillation column as the object of the research, it carried on a disturbance experiment about the outlet air flow of purifier and extractable volume of liquid nitrogen in lower tower. The results demonstrate that when the outlet air flow of purifier decreases, the nitrogen purity in gas is reduced by 0.39%, and the oxygen purity in liquid is reduced by 1.5%;w

A large number of prior empirical research and case studies used qualitative methodology to discuss the fashion brand dilution resulting from consumer base extension from the target group(s) to the nontarget groups and its impacts. From a different perspective, this paper establishes a dynamic brand dilution and performance model, demonstrating how dynamic changes of sales volumes involving the two consumer groups affect the degree of brand dilution and the performance of the brand. We incorporate the factor “brand purity” to the model as a quantitative measure of brand dilution level that aff

Abstract The influence of the atom’s spatial degrees of freedom and the purity of the initial state on the dynamics of Bell non-locality, entanglement, geometric measure of quantum discord (GMQD) and quantum discord in a double Jaynes–Cummings model are investigated. We study the above four quantum correlations for an initial Werner-like state between the electronic states of the two atoms and between the two cavities respectively and find that all these quantum correlations are sensitive to the wave packet width and the purity of the initial state. For Bell non-locality, we find the phenomeno

The hydrotalcite purity can be predicted by means of the trained neural net. Thus, by virtue of the prediction model, the future hydrotalcite purity can be evaluated under random complicated raw material amo

Abstract:

Abstract Liquefied ultrapure noble gases are typically the chosen target for neutrino and dark matter experiments. Commonly, the required grade of purity of such cryogenic liquids in terms of O2 contamination is less than 100 ppt, which makes it necessary for the argon to circulate through adsorption columns filled, typically, with BASF Cu-0226S and Mol Sieve 4A for capturing O2 and H2O. Another requirement that emerged during the design of LBNF-DUNE is the purity of the Liquid Argon (LAr) in terms of N2 concentration, as it was observed that both N2 and O2 contaminations can cause the reducti
