Tuning the metamagnetism of an antiferromagnetic metal

We describe a `disordered local moment' (DLM) first-principles electronic structure theory which demonstrates that tricritical metamagnetism can arise in an antiferromagnetic metal due to the dependence of local moment interactions on the magnetisation state. Itinerant electrons can therefore play a defining role in metamagnetism in the absence of large magnetic anisotropy. Our model is used to accurately predict the temperature dependence of the metamagnetic critical fields in CoMnSi-based alloys, explaining the sensitivity of metamagnetism to Mn-Mn separations and compositional variations found previously. We thus provide a finite-temperature framework for modelling and predicting new metamagnets of interest in applications such as magnetic cooling

An evaluation of Mesozoic rift-related magmatism on the margins of the Labrador Sea: Implications for rifting and passive margin asymmetry

The Labrador Sea is a small (∼900 km wide) ocean basin separating southwest Greenland from Labrador, Canada. It opened following a series of rifting events that began as early as the Late Triassic or Jurassic, culminating in a brief period of seafloor spreading commencing by polarity chron 27 (C27; Danian) and ending by C13 (Eocene-Oligocene boundary). Rift-related magmatism has been documented on both conjugate margins of the Labrador Sea. In southwest Greenland this magmatism formed a major coast-parallel dike swarm as well as other smaller dikes and intrusions. Evidence for rift-related magmatism on the conjugate Labrador margin is limited to igneous lithologies found in deep offshore exploration wells, mostly belonging to the Alexis Formation, along with a postulated Early Cretaceous nephelinite dike swarm (ca. 142 Ma) that crops out onshore, near Makkovik, Labrador. Our field observations of this Early Cretaceous nephelinite suite lead us to conclude that the early rift-related magmatism exposed around Makkovik is volumetrically and spatially limited compared to the contemporaneous magmatism on the conjugate southwest Greenland margin. This asymmetry in the spatial extent of the exposed onshore magmatism is consistent with other observations of asymmetry between the conjugate margins of the Labrador Sea, including the total sediment thickness in offshore basins, the crustal structure, and the bathymetric profile of the shelf width. We propose that the magmatic and structural asymmetry observed between these two conjugate margins is consistent with an early rifting phase dominated by simple shear rather than pure shear deformation. In such a setting Labrador would be the lower plate margin to the southwest Greenland upper plate

Incidence of fibroid and its effects on fertility in Eleme local government area of Rivers State

Background: Fibroid is a gynaecological problem that affects women of reproductive age across the globe especially among the black race. This study was done to evaluate the incidence of fibroid and its effects on fertility in Eleme Local Government Area.Methods: It is a cross-sectional study with 60 participants aged 18-28 years, 29-39 years, 40-49 years, 50-59 years and >60 years.Results: The study revealed that 90% of the respondents have fibroid and 10% do not have fibroid. The effects range from painful menstruation, heavy menses, irregular menstruation and infertility at the values of 63.3%, 48.3%, 51.7% and 86.8% respectively.Conclusions: Though the effects of fibroids are universal, our study population seems to show some effects more common to them

Epidemiology and Treatment Options for COVID-19: A Review

The Coronavirus disease 19 (COVID-19) is a highly transmittable and pathogenic viral infection caused by severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2), which emerged in Wuhan, China and spread around the world. As of 19 June 2020 data from the World Health Organization (WHO) have shown that more than 8457305 confirmed cases have been identified in more than 200 countries, with the number of cases cutting across all continents. On 30th January 2020, the WHO declared COVID-19 as the sixth public health emergency of international concern. Genomic analysis revealed that SARS-CoV-2 is phylogenetically related to severe acute respiratory syndrome-like (SARS-like) bat viruses; therefore, bats could be the possible primary reservoir. The intermediate source of origin and transfer to humans is not known, however, the rapidhuman-to-human transfer has been confirmed widely via droplets or direct contact, and infection has been estimated to have mean incubation period of 6.4 days. Currently, controlling infection to prevent the spread of SARS-CoV-2 is the primary intervention being used. However, public health authorities should keep monitoring the situation closely, as the more we can learn about this novel virus and its associated outbreak, the better we can respond.  Keywords: SARS-CoV-2, COVID-19, China, Phylogenetic, Genomic analysis, Remdesivir Le COVID-19 est une nouvelle maladie mortelle avec des informations limitées sur sa transmissibilité, la gravité de ses séquelles, ses manifestations cliniques et l'épidémiologie. Ce commentaire a analysé l'épidémiologie mondiale du COVID-19 parmi la population vulnérable. L'analyse a révélé que la plupart des cas pédiatriques de COVID-19 ne sont pas graves, mais que des maladies graves associées surviennent toujours chez les enfants. Tous les âges des enfants sont sensibles au COVID-19 et aucune différence significative entre les sexes n'existe. L'infection au COVID-19 pendant la grossesse a eu des conséquences fatales pour les mères, mais moins risquées pour le bébé. Les groupes de points chauds pour le COVID-19 sont les prisons / prisons, les maisons de soins infirmiers / de groupe et les établissements à long terme où résident la plupart des populations vulnérables. Les groupes ethniques minoritaires aux États-Unis et au Royaume-Uni sont exposés de manière disproportionnée à l'infection au COVID-19 et à la mort que les Caucasiens. La différence peut être due au fait que les minorités ethniques sont exposées à des risques plus élevés au travail et aux disparités structurelles économiques et sanitaires de longue date dans les deux pays. Il y a maintenant des changements dans les lignes directrices sur les personnes qualifiées pour recevoir des ventilateurs dans des situations difficiles dans de nombreux pays du monde si le système de santé est débordé.  Mots-clés: COVID-19, épidémiologie, population vulnérabl

Exo-π-bonding to an ortho-carborane hypercarbon atom: systematic icosahedral cage distortions reflected in the structures of the fluoro-, hydroxy- and amino-carboranes, 1-X-2-Ph-1,2-C2B10H10 (X = F, OH or NH2) and related anions

The structures of derivatives of phenyl-ortho-carborane bearing on the second cage hypercarbon atom a pi-donor substituent (F, OH, O-, NH2, NH- and CH2-) were investigated by NMR, X-ray crystallography and computational studies. The molecular structures of these compounds, notably their cage C1-C2 distances and the orientations of their pi-donor substituents (OH, NH2, NH- and CH2-) show remarkable and systematic variations with the degree of exo pi-bonding, which varies as expected with the pi-donor characteristics of the substituent

The Society for Immunotherapy of Cancer consensus statement on immunotherapy for the treatment of prostate carcinoma.

Prostate cancer is the most commonly diagnosed malignancy and second leading cause of cancer death among men in the United States. In recent years, several new agents, including cancer immunotherapies, have been approved or are currently being investigated in late-stage clinical trials for the management of advanced prostate cancer. Therefore, the Society for Immunotherapy of Cancer (SITC) convened a multidisciplinary panel, including physicians, nurses, and patient advocates, to develop consensus recommendations for the clinical application of immunotherapy for prostate cancer patients. To do so, a systematic literature search was performed to identify high-impact papers from 2006 until 2014 and was further supplemented with literature provided by the panel. Results from the consensus panel voting and discussion as well as the literature review were used to rate supporting evidence and generate recommendations for the use of immunotherapy in prostate cancer patients. Sipuleucel-T, an autologous dendritic cell vaccine, is the first and currently only immunotherapeutic agent approved for the clinical management of metastatic castrate resistant prostate cancer (mCRPC). The consensus panel utilized this model to discuss immunotherapy in the treatment of prostate cancer, issues related to patient selection, monitoring of patients during and post treatment, and sequence/combination with other anti-cancer treatments. Potential immunotherapies emerging from late-stage clinical trials are also discussed. As immunotherapy evolves as a therapeutic option for the treatment of prostate cancer, these recommendations will be updated accordingly
