Propriétés magnétiques d'un oxyde amorphe riche en fer : Fe2 O3 (30) BaO (45) B2O3 (25)

La transition magnétique d'un oxyde amorphe riche en fer a été caractérisée par des mesures d'aimantation et susceptibilité magnétique et par spectroscopie Môssbauer de 57Fe. On note de fortes interactions antiferromagnétiques dans le verre et un comportement mictomagnétique à basse température. L'ordre magnétique au-dessous de la transition est de nature spéromagnétique

INFLUENCE OF PREPARATION PROCESS ON PHYSICAL PROPERTIES AND DEVITRIFICATION OF Li2B2O4 (0,9) LiFe5O8 (0,1) GLASSES

Double roller quenching of Li2B2O4(0.9)-LiFe5O8(0.1) has been performed with various melt temperatures and roller speeds. The changes in physical properties or in the devitrification process of the amorphous samples are shown to be related to the LiFe5O8 content variations or to the Fe2+ appearance but not to structural changes of the amorphous state due to preparation processe

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

Implementing core outcomes in kidney disease: report of the Standardized Outcomes in Nephrology (SONG) implementation workshop

There are an estimated 14,000 randomized trials published in chronic kidney disease. The most frequently reported outcomes are biochemical endpoints, rather than clinical and patient-reported outcomes including cardiovascular disease, mortality, and quality of life. While many trials have focused on optimizing kidney health, the heterogeneity and uncertain relevance of outcomes reported across trials may limit their policy and practice impact. The international Standardized Outcomes in Nephrology (SONG) Initiative was formed to identify core outcomes that are critically important to patients and health professionals, to be reported consistently across trials. We convened a SONG Implementation Workshop to discuss the implementation of core outcomes. Eighty-two patients/caregivers and health professionals participated in plenary and breakout discussions. In this report, we summarize the findings of the workshop in two main themes: socializing the concept of core outcomes, and demonstrating feasibility and usability. We outline implementation strategies and pathways to be established through partnership with stakeholders, which may bolster acceptance and reporting of core outcomes in trials, and encourage their use by end-users such as guideline producers and policymakers to help improve patient-important outcomes

CRISTALLISATION DE SOLIDES NON CRISTALLINS DANS LE SYSTEME Li2B2O4 - LiFe5O8

Dans le système Li2B2O4 (100-x) - LiFe5O8 x (0,1 < x < 15 %) les composés amorphes préparés par hypertrempe sont métastables et cristallisent par recuit. Le schéma de cristallisation établi pour Li2B2O490 - LiFe5O8 10 est étendu à tout le système. Les anomalies observées pour la température de vitrification TG sont interprétées à l'aide du diagramme Volume/Température/Etat du système. Les écarts à l'idéalité en sont la cause et peuvent être suivis par analyse enthalpiemétrique (ATD ou DSC).In the system Li2B2O4 (100-x) - LiFe5O8x (0,1<x<15 %) amorphous compounds prepared by ultra fast quenching methods are metastable and crystallize by annealing. The crystallization scheme found for Li2B2O4 90 - LiFe5 O8 10 is extended to all the system. Anomalies observed for the glass temperatures TG are interpreted with the diagram Volume/Temperature/State of the system. They are due to the discrepancies in respect to perfect glass and can be studied by differential scanning calorimetry (DSC or DTA)
