A comparative study of the crystallinity of Polyetheretherketone by using density, DSC, XRD, and Raman spectroscopy techniques.In this work, the microstructure of Polyetheretherketone is first analyzed with usual techniques such as density, Differential Scanning Calorimetry, X-ray Diffraction, and secondly, compared with Raman Spectroscopy. Assessi...

Let \alpha_1,...,\alpha_r be algebraic numbers in a number field K generating a subgroup of rank r in K*. We investigate under GRH the number of primes p of K such that each of the orders of (\alpha_i mod p) lies in a given arithmetic progression associated to (\alpha_i). We also study the primes p for which the index of (\alpha_i mod p) is a fixed...

We present a measurement of the Hubble constant $H_0$ using the gravitational wave (GW) event GW190814, which resulted from the coalescence of a 23 $M_\odot$ black hole with a 2.6 $M_\odot$ compact object, as a standard siren. No compelling electromagnetic counterpart has been identified for this event, thus our analysis accounts for thousands of p...

AbstractDensities of sodium hypophosphite aqueous solution (NaH2PO2) with the molality varied from 1.019143 to 10.43887 mol kg–1 at temperature intervals of 5 K range from 283.15 to 363.15 K at 101.325 kPa were measured by a precise Anton Paar Digital vibrating-tube densimeter. From the density data, the thermal expansion coefficients, apparent vol...

Recent measurements of the D(p,$\gamma)^3$He, nuclear reaction cross-section and of the neutron lifetime, along with the reevaluation of the cosmological baryon abundance from cosmic microwave background (CMB) analysis, call for an update of abundance predictions for light elements produced during the big-bang nucleosynthesis (BBN). While considere...

We describe the first numerical Tolman-Oppenheimer-Volkoff solutions of compact objects in entangled relativity, which is an alternative to the framework of general relativity that does not have any additional free parameter. Assuming a simple polytropic equation of state and the conservation of the rest-mass density, we notably show that, for any ...

Abstract—High-density (95.3–95.8%) CeO2–xα-SiC (x = 10, 20 vol %) composite ceramics have been produced for the first time by spark plasma sintering (SPS) as promising mineral-like materials for inert fuel matrices. The SPS of CeO2–SiC ceramics has been shown to be a three-stage process. The addition of α-SiC particles shifts characteristic tempera...

AbstractThe densities (ρ), speeds of sound (u), and viscosities (η) are reported for binary mixtures of propiophenone with ortho-substituted aniline (2-chloroaniline, 2-methylaniline, and 2-methoxyaniline) over the entire composition range from 303.15 to 318.15 K and at atmospheric pressure 0.1 MPa. The excess/deviation functions (VE, \documentclas...

The density, or specific gravity (SG), of organisms has numerous important implications for their form, function, ecology, and other facets of beings living and dead, and it is especially necessary to apply SG values that are as accurate as practical when estimating their masses which is itself a critical aspect of living things. Yet a comprehensiv...

Airborne laser scanning (ALS) technology delivers large amount of data collected from airborne level. These data are used for many different applications in forestry, civil engineering, environmental studies and others. To acquire the best possible results from the data, accuracy analysis is a necessary part of data processing chain. Therefore, con...
