High-precision measurement of the mass difference between 102Pd and 102Ru
2019
Abstract The Q-value for the neutrinoless double electron capture on 102Pd, Qϵϵ(102Pd), is determined as the atomic mass difference between 102Pd and 102Ru. A precise measurement of the Qϵϵ(102Pd) at the SHIPTRAP Penning trap showed a more than 10σ deviation to the adopted Atomic Mass Evaluation (AME) value. The reliability of the SHIPTRAP measurement was challenged because the AME value was based on numerous experiments including β and electron capture decays and very precise (n, γ) data, all agreeing with each other. To solve the discrepancy, the Qϵϵ(102Pd) has now been determined with the JYFLTRAP Penning trap at the IGISOL facility in the Accelerator Laboratory of the University of Jyva…
Rāmja bungu bubyna tradīcija Latgalē
2020
Maģistra darba “Rāmja bungu bubyna tradīcija Latgalē” mērķis ir izpētīt un raksturot rāmja bungas bubynu kā mūzikas instrumentu un tā spēles tradīcijas robežas 21. gadsimta sākumā. Agrāku pētījumu par rāmja bungām Latvijā ir ļoti maz, tikpat kā nav pētīts rāmja bungu lietojums instrumentālajā muzicēšanā 21. gadsimta sākumā. Darbā autore ir apkopojusi zinātnisku un praktisku informācija par rāmja bungu lietošanu Latgalē dažādās muzicēšanas situācijās, to izplatību, uzbūvi, gatavošanas tehnoloģiju, muzikālajām īpašībām, spēles veidiem, repertuāru. Liela uzmanība ir pievērsta instrumenta gatavošanas un spēles tradīciju pārmantošani, kā arī individuāla muzikanta personiskajam radošumam un izdom…
Teknologian hyväksyminen ja käyttöönotto : instrumentoivien leikkaushoitajien kokemuksia simulaattoriharjoittelusta
2012
Teknologian hyväksymistä ja käyttöönottoa tutkivien teorioiden mukaan yksilön halukkuuteen käyttää uutta teknologiaa vaikuttavat eniten koettu hyödyllisyys ja koettu helppokäyttöisyys. Teknologian ja lääketieteen nopea kehitys asettavat haasteita sairaalan hoitohenkilökunnan koulutukseen. Leikkaussalin teknistyessä leikkaushoitajien on jatkuvasti opittava käyttämään uusia teknologioita. Tutkimusten mukaan leikkaushoitajan ammatillisen pätevyyden kolme tärkeintä osa-aluetta ovat potilasturvallisuudesta huolehtiminen, leikkaushoidon tekniikka sekä hyvät yhteistyötaidot. Simulaation käyttö opetuksessa on lisääntynyt eri aloilla. Kirurgisia leikkaussimulaattoreita käytetään yleisesti kirurgien …
Performance of Lead-Acid Batteries with Nanostructured Electrodes at Different Temperature
2018
In this work we present innovative lead-acid batteries with nanostructured electrodes, which are cycled in a wide range of temperatures typically of lead-acid commercial batteries (EN 61427-1: 2013). In comparison to parameters usually used to commercial batteries, much more stressful conditions in terms of cut-off, charge/discharge rate and discharge were imposed.
High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature
2021
Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…
Les enjeux de la professionnalisation des agents de développement. L’ingénierie territoriale prise en étau entre les conceptions organique et mécanis…
2011
International audience; Cet article relie les mécanismes de régulation de l’action publique territoriale à des enjeux de professionnalisation des agents de développement, acteurs pivot de l’ingénierie territoriale. Ceux-ci, inscrits dans des communautés épistémiques, posent les jalons d’une régulation pragmatique de l’action publique.Cependant, le registre concurrentiel de l’excellence territoriale couplé aux nouvelles formes de contrôles bureaucratique transforme les territoires de projet en segments d’exécution de politiques définies par des agences regroupant expertise et gestion. Au final, la personnalité bureaucratique des agents de développement l’emporte sur leur rôle d’ « agitateurs…
Survey of Research for Performance Measurement of Mobile Manipulators
2016
International audience; This survey provides the basis for developing research in the area of mobile manipulator performance measurement, an area that has relatively few research articles when compared to other mobile manipulator research areas. The survey provides a literature review of mobile manipulator research with examples of experimental applications. The survey also provides an extensive list of planning and control references as this has been the major research focus for mobile manipulators which factors into performance measurement of the system. The survey then reviews performance metrics considered for mobile robots, robot arms, and mobile manipulators and the systems that measu…
High Frequency Data Acquisition System for Modelling the Impact of Visitors on the Thermo-Hygrometric Conditions of Archaeological Sites: A Casa di D…
2018
[EN] The characterization of the microclimatic conditions is fundamental for the preventive conservation of archaeological sites. In this context, the identification of the factors that influence the thermo-hygrometric equilibrium is key to determine the causes of cultural heritage deterioration. In this work, a characterization of the thermo-hygrometric conditions of Casa di Diana (Ostia Antica, Italy) is carried out analyzing the data of temperature and relative humidity recorded by a system of sensors with high monitoring frequency. Sensors are installed in parallel, calibrated and synchronized with a microcontroller. A data set of 793,620 data, arranged in a matrix with 66,135 rows and …
Thermoluminescence response of sodalime glass irradiated with photon and electron beams in the 1-20 Gy range
2011
Abstract The thermoluminescence response of a watch commercial glass was studied after irradiation with photons and electrons, in the range 1–20 Gy, of interest in accidental dosimetry; a linear response was obtained with both beams. This result, together with the satisfactory time stability of the thermoluminescence signal, indicates this glass as a potential material for retrospective dosimetry applications.
