Abstract

Both observations and numerical simulations suggest that Alfvenic waves may carry sufficient energy to sustain the hot temperatures of the solar atmospheric plasma. However, the thermalization of wave energy is inefficient unless very short spatial scales are considered. Phase mixing is a mechanism that can take energy down to dissipation lengths, but it operates over too long a timescale. Here, we study how turbulence, driven by the nonlinear evolution of phase-mixed torsional Alfven waves in coronal loops, is able to take wave energy down to the dissipative scales much faster than the theory of linear phase mixing predicts. We consider a simple model of a transversely nonuniform cylindrical flux tube with a constant axial magnetic field. The flux tube is perturbed by the fundamental mode of standing torsional Alfven waves. We solved the three-dimensional (3D) ideal magnetohydrodynamics equations numerically to study the temporal evolution. Initially, torsional Alfven waves undergo the process of phase mixing because of the transverse variation of density. After only few periods of torsional waves, azimuthal shear flows generated by phase mixing eventually trigger the Kelvin-Helmholtz instability (KHi), and the flux tube is subsequently driven to a turbulent state. Turbulence is very anisotropic and develops transversely only to the background magnetic field. After the onset of turbulence, the effective Reynolds number decreases in the flux tube much faster than in the initial linear stage governed by phase mixing alone. We conclude that the nonlinear evolution of torsional Alfven waves, and the associated KHi, is a viable mechanism for the onset of turbulence in coronal loops., Comment: Accepted in A&A

Abstract

We report on the influence of the chemical composition on the electronic properties of molybdenum oxynitrides thin films grown by reactive sputtering on Si (100) substrates at room temperature. The partial pressure of Ar was fixed at 90 %, and the remaining 10 % was adjusted with mixtures N$_2$:O$_2$ (varying from pure N$_2$ to pure O$_2$). The crystalline and electronic structures and the electrical transport of the films depend on the chemical composition. Thin films grown using oxygen mixtures up 2 % have gamma-Mo$_2$N phase and display superconductivity. The superconducting critical temperature T$_c$ reduces from ~ 6.8 K to below 3.0 K as the oxygen increases. On the other hand, films grown using oxygen mixtures richer than 2 % are mostly amorphous. The electrical transport shows a semiconductor-like behavior with variable-range hopping conduction at low temperatures. The analysis of the optical properties reveals that the samples have not a defined semiconductor band gap, which can be related to the high structural disorder and the excitation of electrons in a wide range of energies, Comment: 16 pages, 9 figures, 1 table

Abstract

We report the influence of 6 MeV Zr$^{4+}$ irradiation and post-irradiation annealing (200 {\deg}C) in the in-field dependences of the critical current densities J$_c$ of 1.3 $\mu$m thick GdBa$_2$Cu$_3$O$_{7-d}$ coated conductors grown by co-evaporation. Samples were irradiated with 6 MeV Zr$^{4+}$ and fluences between 2.3x10$^{11}$ cm$^{-2}$ and 3x10$^{12}$ cm$^{-2}$. The correlation between the superconducting critical temperature T$_c$ and in-field dependences of critical current densities J$_c$ has been analyzed. In addition, random disorder introduced by irradiation was reduced by thermal annealed at 200 {\deg}C. The analysis of our experimental findings indicates that the optimal irradiation (reducing random disorder by annealing) results in the suppression of the self-field J$_c$ of $\simeq$ 10 $\%$ and in-field J$_c$ enhancements nearly doubled at about 5 T. A clear correlation between T$_c$, disorder and self-field J$_c$ is observed. Additional random disorder and nanoclusters suppress systematically T$_c$ and increase the flux creep relaxation at intermediate temperatures (reducing the characteristic glassy $\mu$ value)., Comment: 4 figures

Abstract

We report on the synthesis and characterization of nanocrystalline delta-MoN by crystallization of amorphous thin films grown on (100) Si by reactive sputtering at room temperature. Films with chemical composition MoN were grown using a deposition pressure of 5mTorr with a reactive mixture of Ar/(Ar+N2)=0.5. The as-grown films display mostly amorphous structure. Nanocrystalline delta-MoN phase is obtained after annealing at temperatures above 600 {\deg}C. The superconducting critical temperature Tc depends on film thickness. Thick films (170 nm) annealed at 700 {\deg}C for 30 min display a Tc = 11.2 K (close to the one reported for bulk specimens: 13 K), which is gradually suppressed to 7.2 K for 40 nm thick delta-MoN films. Our results provide a simple method to synthesize superconducting nitride thin films on silicon wafers with Tc above the ones observed for conventional superconductors such as Nb., Comment: 16 pages, 7 figues

Abstract

We report on the critical current density Jc and the vortex dynamics of pristine and 3 MeV proton irradiated (cumulative dose equal to 2x10^16 cm^-2) $\beta$-FeSe single crystals. We also analyze a remarkable dependence of the superconducting critical temperature Tc, Jc and the flux creep rate S on the sample mounting method. Free-standing crystals present Tc =8.4(1)K, which increases to 10.5(1)K when they are fixed to the sample holder by embedding them with GE-7031 varnish. On the other hand, the irradiation has a marginal effect on Tc. The pinning scenario can be ascribed to twin boundaries and random point defects. We find that the main effect of irradiation is to increase the density of random point defects, while the embedding mainly reduces the density of twin boundaries. Pristine and irradiated crystals present two outstanding features in the temperature dependence of the flux creep rate: S(T) presents large values at low temperatures, which can be attributed to small pinning energies, and a plateau at intermediate temperatures, which can be associated with glassy relaxation. From Maley analysis, we observe that the characteristic glassy exponent {\mu} changes from ~ 1.7 to 1.35-1.4 after proton irradiation., Comment: Accepted in Superconductor Science and Technology

Abstract

We report on the superconducting properties of molybdenum nitride thin films grown by reactive DC sputtering at room temperature with a N2:Ar mixture. Thin films grown using 5 % N2 concentration display Tc = 8 K, which is gradually reduced and abruptly disappears for 40 % N2 concentration. This suppression can be associated with changes in the nitrogen stoichiometry from Mo2N to MoN. Our results provide an effective and simple path to prepare Mo2Nx thin films with tunable Tc, which is relevant for the investigation of the fundamental properties and for technological applications., Comment: 7 pages, 3 figures, 1 table, short communication

Abstract

We report the influence of crystalline defects introduced by 6 MeV $^{16}$O$^{3+}$ irradiation on the critical current densities J$_c$ and flux creep rates in 1.3 $\mu$m thick GdBa$_2$Cu$_3$O$_{7-d}$ coated conductor produced by co-evaporation. Pristine films with pinning produced mainly by random nanoparticles with diameter close to 50 nm were irradiated with doses between 2x10$^{13}$ cm$^{-2}$ and 4x10$^{14}$ cm$^{-2}$. At temperatures below 40 K with the magnetic field applied parallel (H//c) and at 45{\deg} (H//45{\deg}) to the c-axis, the in-field J$_c$ dependences can be significantly improved by irradiation. For doses of 1x10$^{14}$ cm$^{-2}$ the J$_c$ values at $\mu$$_0$H = 5 T are doubled without affecting significantly the J$_c$ at small fields. Analyzing the flux creep rates as function of the temperature in both magnetic field configurations, it can be observed that the irradiation suppresses the peak associated with double-kink relaxation and increases the flux creep rates at intermediate and high temperatures. Under 0.5 T, the flux relaxation for H//c and H//45{\deg} in pristine films presents characteristic glassy exponents $\mu$ = 1.63 and $\mu$ = 1.45, respectively. For samples irradiated with 1x10$^{14}$ cm$^{-2}$, these values drop to $\mu$ = 1.45 and $\mu$ =1.24, respectively., Comment: 19 pages, 7 figures

Abstract

We report on the influence of doping on vortex dynamics in 3 MeV proton-irradiated single crystals of CaK(Fe1− x Ni x)4As4 (1144, x = 0.015, 0.025, and 0.03) and Ba(Fe1− x Co x)2As2 (x = 0.04, 0.062, 0.066 and 0.074). Non-irradiated crystals of the 1144 system display superconducting critical temperatures ranging from 31 K for x = 0.015–20.5 K, as doping increases to 0.03. On the other hand, pristine crystals of the 122 system show Tc values between 14.6 and 23.6 K, with the maximum Tc occurring at intermediate doping levels. The fluence was set at 3 × 1016 p cm−2, resulting in a decrease in the Tc by around 1.5 K for all samples and significantly affecting the vortex dynamics by reducing the flux creep relaxation compared to previously reported values for unirradiated crystals. Parameters such as vortex pinning energy U 0 and the glassy exponent μ dependencies on doping and magnetic field strength are identified. For the 1144 system, U 0 reaches values approaching 500 K for small fields in samples with Tc = 29.3 K (x = 0.015), systematically decreasing to around 200 K as Tc falls below 20 K. Furthermore, U 0 decreases as the field increases to 3 T for the same sample, varying from approximately 250 K to 100 K as Tc decreases. These changes are typically accompanied by modifications in μ, gradually increasing from values around 1 towards 1.5, corresponding to small bundle relaxation in the collective creep theory. Despite differences in the substitutional disorder and magnetic phase diagram with respect to the 1144 system, the results for 122 single crystals follow a similar tendency in which U 0 usually reduces and μ increase rise as the applied magnetic field is increased. Due to moderate U 0 in these systems (few hundreds of kelvins), the resulting decay of persistent current at liquid helium temperatures is primarily determined by a balance between U 0 and bundle size contribution. These findings provide valuable insights for potential applications of these systems, particularly in the context of intrinsic superconducting parameters and the resulting pinning landscape.

Abstract

We investigate experimentally and theoretically the electron emission in collisions between He atoms and Li$^{q+}$ (q=1,2) projectiles at intermediate-high incident energies. We report on measured absolute values of double differential cross-sections, as a function of the emitted electron energy and angle, at a collision energy of 440~keV/u. The different contributions from target-ionisation, projectile-ionisation, and simultaneous target-projectile ionisation are calculated with the quantum-mechanical Continuum Distorted Wave and Continuum Distorted Wave -- Eikonal Initial State models, and with Classical Trajectory Monte Carlo simulations. There is an overall good agreement of the calculations with the experimental data for electron emission cross-sections., Comment: 19 pages, 6 figures

Abstract

Abstract\nImplications for the PracticeOncology patients often experience swallowing difficulties, which can compromise adherence to treatment and consequently reduce its effectiveness. Improper handling of these hazardous drugs can lead to the risk of inhalation of particles or other exposures endangering the health of the persons involved such as nurses and pharmacists. The aim of this review is to analyse and update the recommendations for the manipulation of oral antineoplastic drugs in patients with swallowing difficulties. A literature review of articles, websites, guidelines and other documents published up to about the conditions of handling and administration of oral antineoplastic agents in oncology and oncohaematology was carried out. A table of 110 active principles was compiled. The information was grouped according to the name of the drug, instructions for oral and nasogastric tube administration and suggested recommendations. Among the drugs reviewed, 66.4% were suitable for dissolution. Although there is a lot of information in the literature, the nonstop development of new oncological drugs requires continuous updating. Therefore, we have collected the most recent data to provide a consultation tool for healthcare professionals and patients with swallowing difficulties.This review can be used by all types of healthcare professionals, especially nurses, who handle oncological medicinal drugs. In addition, the safest handling methods for the worker have been recommended. [ABSTRACT FROM AUTHOR]

Abstract

Los arreglos agroforestales con cacao poseen una estructura diversificada, la cual influye sobre el comportamiento de las raíces finas, cuya distribución está influenciada por las diferentes prácticas culturales. El objetivo del presente trabajo fue estudiar la distribución, el aporte de biomasa de raíces finas en relación con la densidad aparente y el porcentaje de humedad en arreglos agroforestales con cacao en el Centro de Investigaciones CIMAZ Macagual (1°37’LN y 75°36’LO). El muestreo se desarrolló en tres arreglos agroforestales con cacao clasificados en sombra intensa, semisombra y pleno sol. Para la extracción de la biomasa de raíces se utilizó el cilindro de volumen conocido cada 10cm hasta llegar a 1m de profundidad. Las raíces finas fueron extraídas a través de una malla de un tamaño
