Abstract
We report magnetite (Fe3O4) nanoparticles synthesized by the hydrothermal method in egg white solution. The egg white solution is a good surfactant which can also reduce the phase impurities in the prepared products. The structure and magnetic properties of the synthesized samples were studied as a function of calcination temperatures. The samples were characterized by X-ray diffraction and selected area electron diffraction which indicates the cubic spinel ferrite structure without any other phase impurities in all synthesized Fe3O4 nanoparticles. The particle sizes ranging from 5 to 50 nm were observed by transmission electron microscopy. The X-ray absorption near edge structure spectra show the Fe3+/Fe2+ mixed oxidation states in all samples. The hysteresis loops at room temperature were detected in the Fe3O4 nanoparticles suggesting the ferrimagnetic behavior. A positive correlation was found between reaction temperature and saturation magnetization.

Um dos empecilhos ao crescimento da área cultivada com melancia tem sido a escassez de informações técnicas, sobretudo relativas à nutrição da cultura, o que pode afetar diretamente na produtividade e qualidade dos frutos. A marcha de absorção de nutrientes é uma ferramenta fundamental para o conhecimento da exigência nutricional da planta em diferentes estádios fenológicos, mostrando a época certa para aplicação dos nutrientes. Diante o exposto, este trabalho teve como objetivo determinar o crescimento e marcha de acúmulo de macronutrientes pela cultura da melancia cv. Top Gun em área de várzea no município da Lagoa da Confusão – TO. O experimento foi conduzido em propriedade rural localizada no município da Lagoa da Confusão – TO, no período de junho a agosto de 2016. O delineamento experimental utilizado foi em blocos casualizados com cinco épocas de coleta das plantas (15, 30, 45, 60 e 75 dias após a semeadura), em quatro repetições, sendo que em cada repetição foram coletadas duas plantas. Após cada coleta, as plantas foram fracionadas em parte aérea (ramas e folhas) e frutos, para determinação da matéria seca constante. Posteriormente realizou-se a determinação dos teores dos nutrientes N, P, K, Ca, Mg e S, sendo utilizado o método de extração por digestão nitro-perclórica. Os nutrientes mais acumulados pelas plantas de melancia durante o ciclo foram K, N, Ca, Mg, P e S, com 101,27, 75,54, 59,45, 14,91, 13,09 e 5,84 kg ha-1, respectivamente. Os nutrientes mais transportados pelos frutos foram K, N, P, Mg, Ca e S, correspondendo a 80,56, 50,96, 11,16, 6,45, 5,93 e 4,88 kg ha-1, respectivamente. O período de maior acúmulo de matéria seca em plantas de melancia cv. Top Gun foi de 30-45 DAS para a parte aérea (ramas e folhas) e 60-75 DAS para os frutos.

El impacto del caso Artavia Murillo en materia de derechos reproductivos
Authors: De Cicco Andrés Oscar 
Published: February 2021

Las técnicas de reproducción asistida han contribuido a que personas biológicamente imposibilitadas para concebir puedan acceder a servicios de atención médica relacionados a la salud reproductiva en igualdad de condiciones que el resto de los individuos y, de ese modo, ver cumplimentado no solo su derecho humano de acceso a la salud, sino un conjunto de derechos fundamentales análogos como es el derecho a la vida privada y familiar y el derecho a formar una familia. En esta dirección, procederé a analizar la sentencia "Artavia Murillo vs. Costa Rica" dictada por la Corte Interamericana de Derechos Humanos. Si bien la sentencia recae sobre un caso en concreto, significó en la región un antes y un después en materia de derechos humanos y derechos reproductivos en particular, ya que recae sobre un tema en el que, aún en la actualidad, no existe un consenso político ni moral.

Assisted reproduction techniques have contributed to the fact that people who are biologically unable to conceive can access to health care services related to reproductive health on equal terms with the rest of the individuals and, consequently, not only have their human rights to access to health fulfilled, but a set of similar fundamental rights such as the right to private and family life and the right to found a family. In this direction, I will proceed to analyze the judgment "Artavia Murillo vs. Costa Rica" issued by the Inter-American Court of Human Rights. Although the sentence falls on a specific case, it meant a before-and-after in the region in terms of ​​human rights and reproductive rights in particular, since it falls on an issue on which even today there is no political or moral consensus.
La Salud y la regulación alimentaria europea: el nivel de riesgo tolerado
Authors: Suñer Marc 
Published: February 2021

T. Boer & Zonen es una empresa neerlandesa productora de carne. Por violaciones de la normativa alimentaria europea, se le imponen sendas multas que, tras ser recurridas, culminan en una cuestión prejudicial del tribunal en cuestión ante Tribunal de Justicia de la Unión Europea sobre si la refrigeración de los productos puede entenderse realizada dentro de los camiones frigoríficos (encontrándose estos en las dependencias del matadero), como pretende la empresa, o debemos atender a la literalidad de la norma y otros requisitos, que este proceso solo puede entenderse realizado en el sitio especificado como “matadero”. Por la propia naturaleza del bien jurídico y el elevado nivel de precaución y riesgo tolerable que ha asumido la Unión Europea, el Tribunal de Justicia de la Unión Europea falla en favor de la interpretación consonante con dichos principios y de manera desfavorable para la empresa.

Boer & Zonen is a meat producing Dutch company. Due to breaches of the European food legislation, it is fined and, after the appeal process, culminates in a preliminary ruling from the appeals court to the Court of Justice of the European Union about whether it can be interpreted that the refrigeration process requirement was met if it was performed in the freezing trucks (being these located within the slaughterhouse), as the company pretends, or it must be understood as met only if it was performed as the literality of the rule expresses and also other requirements. Given the nature of the legally protected good and the elevated level of precaution and risk tolerance assumed by the European Union, the Court of Justice of the European Union rules in favor of the interpretation compatible with said standards and against the company.

Abstract
We report a new free-floating planet (FFP) candidate, KMT-2017-BLG-2820, with Einstein radius θ
E ≃ 6 μas, lens-source relative proper motion μ
rel ≃ 8 mas yr−1, and Einstein timescale t
E = 6.5 hr. It is the third FFP candidate found in an ongoing study of giant-source finite-source point-lens (FSPL) events in the KMTNet database and the sixth FSPL FFP candidate overall. We find no significant evidence for a host. Based on their timescale distributions and detection rates, we argue that five of these six FSPL FFP candidates are drawn from the same population as the six point-source point-lens (PSPL) FFP candidates found by Mróz et al. in the OGLE-IV database. The θ
E distribution of the FSPL FFPs implies that they are either sub-Jovian planets in the bulge or super-Earths in the disk. However, the apparent “Einstein desert” (10 ≲ θ
E/μas ≲ 30) would argue for the latter. Whether each of the 12 (six FSPL and six PSPL) FFP candidates is truly an FFP or simply a very wide-separation planet can be determined at first adaptive optics (AO) light on 30 m telescopes, and earlier for some. If the latter, a second epoch of AO observations could measure the projected planet–host separation with a precision of

. At the present time, the balance of evidence favors the unbound-planet hypothesis.

Abstract
We have used the Habitable Zone Planet Finder (HPF) to gather high-resolution, high signal-to-noise near-infrared spectra of 13 field red horizontal branch (RHB) stars, one open cluster giant, and one very metal-poor halo red giant. The HPF spectra cover the 0.81–1.28 μm wavelength range of the zyJ bands, partially filling the gap between the optical (0.4–1.0 μm) and infrared (1.5–2.4 μm) spectra already available for the program stars. We derive abundances of 17 species from LTE-based computations involving equivalent widths and spectrum syntheses, and estimate abundance corrections for the species that are most affected by departures from LTE in RHB stars. Generally good agreement is found between HPF-based metallicities and abundance ratios and those from the optical and infrared spectral regions. Light element transitions dominate the HPF spectra of these red giants, and HPF data can be used to derive abundances from species with poor or no representation in optical spectra (e.g., C i, P i, S i, K i). Attention is drawn to the HPF abundances in two field solar-metallicity RHB stars of special interest: one with an extreme carbon isotope ratio, and one with a rare, very large lithium content. The latter star is unique in our sample in exhibiting very strong He i 10830 Å absorption. The abundances of the open cluster giant concur with those derived from other wavelength regions. Detections of C i and S i in HD 122563 are reported, yielding the lowest metallicity determination of [S/Fe] from more than one multiplet.
