The shift from electronic identification to digital identity is indicative of a shift in the spirit of the European texts. Whereas the legislator had thought of a purely technical identification process in 2014, in 2021 it is focusing on the role of the individual. The individual must be at the heart of the decision-making process as soon as data relating to his or her identity are concerned.

Radiation-induced attenuation in aluminum- and aluminum-thulium-doped optical fibers.

Gamma-ray-induced attenuation in Al-doped and Al/Tm-co-doped optical fibers is investigated in the visible and near-infrared domain up to 1 Gy. The behavior of radiation-induced attenuation (RIA) regarding dose and dose rate is discussed. Our results reveal high sensitivities for both types of fibers at low gamma ray doses and also reveal that Al/Tm fibers are very promising at original interrogation wavelengths for dosimetry applications.

Influence of temperature and dose rate on radiation-induced attenuation at 1542 nm in fluorine-doped fibers.

Radiation-induced attenuation (RIA) at 1542 nm of fluorine-doped fibers under gamma radiation source has been investigated for different dose rates and temperatures. Both the temperature and dose rate dependencies are unusual. First, the fiber presents an enhanced low dose rate sensitivity that is favored by increasing temperature.

Towards the intrahour forecasting of direct normal irradiance using sky-imaging data.

Increasing power plant efficiency through improved operation is key in the development of Concentrating Solar Power (CSP) technologies. To this end, one of the most challenging topics remains accurately forecasting the solar resource at a short-term horizon. Indeed, in CSP plants, production is directly impacted by both the availability and variability of the solar resource and, more specifically, by Direct Normal Irradiance (DNI).

Uncertainty in measurement for 43 biochemistry, immunoassay, and hemostasis routine analytes evaluated by a method using only external quality assessment data.

Background: International organizations require from medical laboratories a quantitative statement of the uncertainty in measurement (UM) to help interpret patient results. The French accreditation body (COFRAC) recommends an approach (SH GTA 14 IQC/EQA method) using both internal quality control (IQC) and external quality assessment (EQA) data. The aim of this work was to validate an alternative way to quantify UM using only EQA results without any need for IQC data.

Field assessment of a model for fungicide effects on intraplant spread of stem rust in perennial ryegrass seed crops.

Intraplant spread of stem rust (Puccinia graminis subsp. graminicola) in perennial ryegrass during tiller extension is a major determinant of epidemic severity and is dominated by stem extension dynamics. Simple equations for extension of inflorescence and internodes are presented and parameterized.

[State of the art and method validations: application to fidelity performance].

Current events of clinical laboratories in France argue a lot about quality management. Setting up an assurance quality system can be realized in many approaches listed by increasing requirements: respect of reglementary Guide de bonne exécution des analyses (GBEA), BioQualite qualification, certification and at last accreditation. This last step corresponds to the recognition of the competence of the laboratory to execute specifics tasks.

[About the choice of acceptability limits in external quality assessment schemes].

Quality control schemes are a practical tool used in clinical laboratories and an essential element for any quality assurance process. In France, external quality assessment schemes (EQAS) can be mandatory (as national quality control organized by AFSSAPS) or voluntary as those suggested by French associations (ProBioQual, CTCB or Asqualab). These EQAS usually evaluate participants according to their performances: this ranking depends on acceptability limits which are here compared.

[Blood screening of benzodiazepines and tricyclic antidepressants. Results of 5 years of interhospital controls].

Pro bio Qual Association of Lyon have proposed a control which include the control for detecting benzodiazepines (BZD) and tricyclic antidepressants (ADT) since 2000. With this control, we have evaluated the specificity and the sensitivity of techniques used. We have tested the maprotiline reactivity too (tetracyclic antidepressant).

[Digoxin assay: results of 10 years of intralaboratory controls].

Serum digoxin measurement is often performed in medical laboratories. A professional association specialized in quality control, based in Lyon, has been organizing punctual controls of medication measurement for the past ten years. The results are analysed in term of intra and inter-technique precision, difference between methods and specificity in regard to endogenous or exogenous interfering substances.

French experience of quality assessment of quantitative urinary analysis.

Since 1986, clinical biochemists from the Rhône alpes area, in collaboration with a non-profit-making association (Pro Bio Qual), have been conducting an inter-laboratory quality assurance program for quantitative urine analysis. We investigated the precision and accuracy of individual methods and measurement systems routinely used in the monthly control for 13 analytes: albumin, alpha-amylase, calcium, chloride, creatinine, glucose, magnesium, phosphorus, potassium, total protein, sodium, urea, and urate. The number of laboratories participating in the program increased from 60 in 1986 to 277 in 1999.

Open-thorax guinea pig model for defibrillation.

Background And Purpose: Guinea pigs are used as models for study of ventricular tachyarrhythmias (VT); however, the tachyarrhythmia often is transient and does not persist. We developed an open-thorax guinea pig model of sustained ventricular fibrillation (VF).

Methods: Bilateral thoracotomy was performed on eight guinea pigs weighing 865 to 1,464 g, and two sutures were positioned in the right ventricular apex for the purpose of pacing.

Improved guinea pig model of cardiac tachyarrhythmias.

Guinea pigs are frequently used as models for ventricular tachyarrhythmias, including polymorphic ventricular tachycardia (VT) and ventricular fibrillation. However, applications of the model for short-term therapies are limited because the arrhythmias are transient, typically lasting <5 sec. Thus, spontaneous termination cannot be easily distinguished from effective short-term therapy in standard models.

Studies of reproductive competence in male Dirofilaria immitis treated with milbemycin oxime.

Normal adult Dirofilaria immitis from a microfilaremic donor dog and D. immitis from donors rendered microfilaria (MF) negative by seven consecutive monthly doses of milbemycin oxime (500 micrograms/kg) were transplanted into three previously uninfected and untreated dogs. Two dogs received reciprocal combinations of treated and untreated D.

[Mucous diaphragm of the cervical esophagus. Apropos of 38 cases discovered during upper endoscopy at the General Hospital of Dakar. Relationship with the Kelly-Paterson or the Plummer-Vinson syndrome].

At the occasion of 15,000 high endoscopies performed during the past 5 years at the general Hospital of Dakar (Senegal) 38 mucous diaphragms of cervical esophagus were discovered. 36 patients are Black Senegalese; 29 females and 9 males with a mean age of 37. Dysphagia was present 29 times and anemia 22 times.

[The value of laparoscopy. Results of 600 studies performed in an internal medicine department at the General Hospital of Dakar].

600 laparoscopic examinations were performed in an Internal Medicine Department of the general Hospital Dakar (Senegal) from 1984 to 1989 in 402 males and 198 females aged from 7 to 82 years. This examination of simple and quick procedure well tolerated under simple premedication, should be performed only after diffusion of the pneumoperitoneum, per- foration being the major risk. Even if liver cell carcinoma and cirrhosis represent more than an half of the examined cases (52%) due to their high frequency, exploration of peritoneal pathology is the best indication for laparoscopy.

[Importance of laparoscopy. Results of 600 examinations performed in the Internal Medicine Department of the Hôpital Principal of Dakar].

At Dakar General Hospital between 1984 and 1989, 402 men and 198 women aged between 7 and 82 years were examined by laparoscopy. This simple, rapid examination, well tolerated after simple premedication, should only be undertaken after complete diffusion of the pneumoperitoneum because of a major perforation risk: 2 deaths unfortunately occurred during the above series. CPF's and cirrhosis account for more than half the cases (52%) and Laparoscopy is most useful in exploring the peritoneal pathology.
