Resumen
An update of the hadronic vacuum polarisation contributions to the muon magnetic anomaly and to the running of the electromagnetic couplings constant at the Z-boson mass is presented. Newest e+e−→ hadrons cross-section data mainly from the BABAR and VEPP-2000 experiments have been included. For the muon (g−2)/2, the lowest-order hadronic contribution is evaluated to be (693.1 ± 3.4) · 10−10, improving the precision of our previous evaluation by 21%. The full Standard Model prediction differs by 3.5 σ from the experimental value. The five-quark hadronic contribution to $ \alpha (\mathop m\nolimi

Pale yellow transparent single crystals of Ca6[Al2N6] (P21/c, No. 14, a = 693.7(3), b = 614.9(3), c = 987.1(5) pm, ß = 94.01(5)°; Z = 4) and colourless transparent single crystals of Ba3[Al2N4] (Pnna, No. 52, a = 617.9(2), b = 1005.2(4), c = 1023.0(4) pm; Z = 4) were obtained from reactions of mixtures of the representative metals with nitrogen at Tmax = 1000 °C. The crystal structure of Ca6[Al2N6] contains isolated units [Al2N6]12- built of two edge-sharing tetrahedra. Ba3[Al2N4] is an isotype of Sr3[Al2N4].

Resumen
Abstract Single crystals of Pb6(AsO4)[B(AsO4)4] (I) and Pb(BAsO5) (II) were obtained by melting B2O3, As2O5 and PbO at 800 °C. X-ray investigation led to the space group (I): S41 -P4̄ (Nr. 81) with a = 715.4(1), c = 976.2(3) pm, Z = 1 and (II): C32 -P31 (Nr. 144) with a = 712.2(1), c = 693.5(2) pm, Z = 3. While (II) is isotypic to the Stillwellite structure, Pb6(AsO4)[B(AsO4)4] represents a completely novel type of crystal structure. Boron and arsenic are tetrahedrally coordinated by oxygen. These polyhedra form two kinds of isolated anions: AsO43- and B(AsO4)49-. Lead is eightfold coordinated

Resumen
Using goat manure may substantially increase cowpea bean productivity. This study evaluated the yield of ‘pingo de ouro’ cowpea bean under different sowing densities and goat doses in the region of Mossoró, Brazil. The experiment was conducted from October to December 2016 at the Experimental Farm Rafael Fernandes, Mossoró-RN, Brazil. Treatments arranged in two-way factorial with four goat manure doses (0.0, 0.5, 1 and 2 kg m-1), and two sowing densities of bean (75,000 and 37,500 plants ha-1), with three replicates.

Resumen
The COVID-19 pandemic has led to the search for new molecules with antiviral activity against SARS-CoV-2. The entry of the virus into the cell is one of the main targets for inhibiting SARS-CoV-2 infection. Natural products are an important source of new therapeutic alternatives against diseases. Pseudotyped viruses allow the study of SARS-CoV-2 viral entry inhibitors, and due to their simplicity, they allow the screening of a large number of antiviral candidates in Biosafety Level 2 facilities. We used pseudotyped HIV-1 with the D614G SARS-CoV-2 spike glycoprotein to test its ability to infec

Resumen
A combination of NaOH activation and continuous pyrolysis of biomass is used to prepare N and O dual-doped hierarchical porous carbon as the carrier of Li—S batteries from egg, yolk and albumen respectively. Among the three sources, the biomass porous carbon derived from albumen has the most abundant hierarchical pore morphology. Its specific surface area, average pore diameter, and sulfur loading are 693.0 m2 · g−1, 3.1 nm and 62.0 wt.%, respectively. The albumen-derived porous carbon/sulfur (AC/S) electrode exhibits excellent reversibility and electrochemical performance (1115 mAh · g−1 at 0

Resumen
Background: The insertion of a mesh “internal bra” has been used in cosmetic breast procedures for soft-tissue reinforcement as a means to mitigate postoperative ptosis. However, there have been concerns regarding complications as a result of mesh placement and a lack of quantitative data regarding postoperative cosmetic outcomes. Methods: Articles that assessed the effects of the mesh internal bra for soft-tissue support on cosmetic and patient-reported outcomes, complications, and surveillance were reviewed. Meta-analysis was performed to determine the overall complication rates, and cosmeti

Resumen
Rhipicephalus sanguineus is an ectoparasite of importance for both animal and public health. Purpose: The objective of this study was to establish a colony of R. sanguineus under laboratory conditions in order to characterize its biological cycle and its reproductive parameters while parasitizing the alternative host most frequently used as experimental model. Methods: Adult ticks were collected in veterinary clinics in the Veracruz-Boca del Rio metropolitan area between November 2020 and November 2021 and a rabbit model was used as host under controlled conditions (28°C ± 2°C and 80% ± 10% re
