Continuous Discharge Monitoring Using Non-contact Methods for Velocity Measurements: Uncertainty Analysis
2014
At gauged site, water stage and discharge hydrographs can be related also during unsteady flow conditions, using the one-dimensional diffusive hydraulic model, DORA, and exploiting sporadic surface velocity measurements carried out with a radar sensor, during the rising limb of the flood. Indeed, starting from the measured surface velocity, the application of a simplified entropic velocity distribution model allows obtaining the benchmark discharge for the Manning’s roughness calibration. The aim of this work is twofold. First, to address the uncertainty of the approach. Second, to detect the minimum water level along the rising limb in which the occasional surface velocity measurement shou…
Comparison of the sensitivity to spectral variation of voltage- and current-matched tandem devices with luminescent coupling and thickness optimizati…
2016
Using models that do not take luminescent coupling into account, voltage-matched tandem devices have previously been shown to be less sensitive to spectral variation than their current-matched counterparts. The present paper compares the spectral sensitivity of voltage-matched and current-matched tandem devices by applying a detailed balance model that takes luminescent coupling into account. Current-matched stacks where the thickness of the top cell thickness has been optimized are also considered. The main finding is that luminescent coupling reduces the difference in spectral sensitivity between voltage-matched and current-matched devices. There is still a significant difference, however…
The Influence of Requirements in Software Model Development in an Industrial Environment
2017
Textual description of requirements is a specification technique that is widely used in industry, where time is key for success. How requirements are specified textually greatly depends on human factors. In order to study how requirements processing is affected by the level of detail in textual descriptions, this paper compares enriched textual requirements specifications with non-enriched ones. To do this, we have conducted an experiment in industry with 19 engineers of CAF (Construcciones y Auxiliares de Ferrocarril), which is a supplier of railway solutions. The experiment is a crossover design that analyzes efficiency, effectiveness, and perceived difficulty starting from a written spec…
The rights and obligations of persons detained in custody in Poland

Przyjęty przez ustawodawcę katalog uprawnień i obowiązków osób tymczasowo aresztowanych uwzględnia konstytucyjną zasadę zakazu naruszania godności ludzkiej. W Kodeksie karnym wykonawczym uwzględniono prawo aresztanta do powiadomienia o miejscu swojego pobytu, prawo do obrony, prawo do korzystania z wyżywienia, środków leczniczych i higienicznych otrzymywanych spoza aresztu śledczego i prawo do zatrudnienia. Natomiast do podstawowych obowiązków tymczasowo aresztowanych zaliczono przestrzeganie postanowień regulaminowych i porządkowych oraz wykonywanie prac porządkowych w obrębie aresztu śledczego. Jednak realizacja powyższych uprawnień oraz egzekwowanie obowiązków nastręcza trudności związan…
Production of hydrogen negative ions in an ECR volume source: balance between vibrational excitation and ionization
2018
International audience; The operation of an ECR-driven (2.45 GHz) hydrogen negative ion source is studied. Electron densities and temperatures are investigated with electrostatic probes and negative ion densities are measured with laser photodetachment. Vacuum ultraviolet irradiance measurements are focused on molecular transitions to the ground state while high-resolution visible emission spectroscopy is used to study the transitions between excited states for both molecules and atoms. The standalone operation of the source is found to be more efficient in higher pressures (12 mTorr) where negative ion densities are as high as 4×109 cm−3. Further investigation on the operation of the sou…

Development of a simple, biocompatible and cost-effective Inulin-Diethylenetriamine based siRNA delivery system
2015
Small interfering RNAs (siRNAs) have the potential to be of therapeutic value for many human diseases. So far, however, a serious obstacle to their therapeutic use is represented by the absence of appropriate delivery systems able to protect them from degradation and to allow an efficient cellular uptake. In this work we developed a siRNA delivery system based on inulin (Inu), an abundant and natural polysaccharide. Inu was functionalized via the conjugation with diethylenetriamine (DETA) residues to form the complex Inu-DETA. We studied the size, surface charge and the shape of the Inu-DETA/siRNA complexes; additionally, the cytotoxicity, the silencing efficacy and the cell uptake-mechanis…

Interventions for improving psychological detachment from work: A meta-analysis.
2021
Psychological detachment from work during off-job time is crucial to sustaining employee health and well-being. However, this can be difficult to achieve, particularly when job stress is high and recovery is most needed. Boosting detachment from work is therefore of interest to many employees and organizations, and over the last decade numerous interventions have been developed and evaluated. The aim of this meta-analysis was to review and statistically synthesize the state of research on interventions designed to improve detachment both at work and outside of it. After a systematic search (covering the period 1998-2020) of the published and unpublished literature, 30 studies with 34 interv…
