Complex Rating Curves for Sharp Crested Orifices and Rectangular or Triangular Weirs under Unsteady Flow Conditions
2021
The importance of discharge measurements is fully acknowledged in many research fields, mostly in hydrology. Numerous measurement devices and various overflow structures have been proposed for discharge measurements; however, their use is based on calibrated simple stage discharge relationships that may cause significant errors when unsteady flow conditions occur. This issue is quite common because of rainfall and runoff temporal variability that inhibits the achievement of the steady state. Although this issue has already been experimentally investigated, it seems that a physically based line of approach has not been attempted before. In this paper, unsteady stage discharge relationships o…
Effects of deep cervical flexor training on pressure pain thresholds over myofascial trigger points in patients with chronic neck pain.
2012
The purpose of this study was to assess the effects of a low-load training program for the deep cervical flexors (DCFs) on pain, disability, and pressure pain threshold (PPT) over cervical myofascial trigger points (MTrPs) in patients with chronic neck pain.Thirty patients with chronic idiopathic neck pain participated in a 6-week program of specific training for the DCF, which consisted of active craniocervical flexion performed twice per day (10-20 minutes) for the duration of the trial. Perceived pain and disability (Neck Disability Index, 0-50) and PPT over MTrPs of the upper trapezius, levator scapulae, and splenius capitis muscles were measured at the beginning and end of the training…
Through the Eyes of an Entangled Teacher: When Classical Musical Instrument Performance Tuition in Higher Education is Subject to Quality Assurance
2020
What happens when a classical music instrument performance course at a Norwegian state university study programme is assessed for quality following a standardized procedure? The article explores frictions and negotiations between managerial quality assurance and classical music performance education in a contextual sense, focusing particularly on the teacher-student relation. I employ my own experience as an instrument performance teacher in a Western Classical Music performance study programme while drawing on state acts, regulations, managerial processes, educational politics, funding, and classical music performance education’s habitus and heritage. I begin by addressing the institution …
Thermal conductivity measurement of insulating innovative building materials by hot plate and heat flow meter devices: A Round Robin Test
2019
Abstract The characterization of thermal insulation properties of construction materials represents a fundamental step on the building insulation assessment. In recent years innovative materials have been introduced in the market to fulfill the continuously growing requirements of energy saving and sustainability, and their performance is not so reliable and mature as it happens for traditional insulators. The work presents a Round Robin Test realised among six European laboratories hosting hot plates devices to measure the thermal conductivity of four different materials: aerogel, vacuum insulation panels, polystyrene and birch wood fibre insulation boards. After the definition of the comm…
Piegādes ķēdes vadības efektivitātes novērtējums mazumtirdzniecības zīmolos: IKEA piemērs
2020
Mazumtirdzniecības nozares uzņēmumiem piegādes ķēdes vadība ir svarīgs aspekts. Tomēr joprojām daudziem no tiem ir grūtības ar efektīvās piegādes ķēdes novērtēšanas sistēmas radīšanu un ieviešanu. Šī darba galvenais mērķis ir izveidot dzīvotspējīgu piegādes ķēdes novērtēšanas sistēmas modeli mazumtirdzniecības uzņēmumiem. Darba gaitā autors ir izpētījis un izanalizējis pieejamu literatūru par piegādes ķēdes pārvaldību un tās novērtēšanas sistēmas efektivitāti, izpētījis esošo piegādes ķēdes novērtēšanas sistēmu IKEA uzņēmumā, kas kalpoja par pētījumu objektu, kā arī veicis intervijas ar nozares ekspertiem piegādes ķēžu pārvaldībā. Rezultātā autoram izdevās identificēt un klasificēt radītāju…
Valeurs de référence du valproate de sodium (CAS n°1069-66-5). Valeurs toxicologiques de référence par voie orale et inhalation, valeurs limites d’ex…
2021
Le site de Sanofi situé à Mourenx, dans le bassin industriel de Lacq (64), produit un médicament antiépileptique, la Dépakine®, dont le principe actif est le valproate de sodium (VPS). Ce site est une installation classée pour la protection de l’environnement (ICPE) soumise à autorisation au titre de l’article L.511-1 et suivants du Code de l’environnement. Les rejets dans l’environnement d’une telle installation sont encadrés par des limites établies sur la base d’une évaluation quantitative des risques sanitaires (EQRS). En 2017, Sanofi Chimie a réalisé une évaluation de l’impact sur la santé et l’environnement des rejets atmosphériques de valproate, en utilisant des valeurs toxicologique…
Do Children Cooperate Conditionally?:Adapting the Strategy Method for First-Graders
2020
We develop a public goods game (PGG) to measure cooperation and conditional cooperation in young children. Our design addresses several obstacles in adapting simultaneous and sequential PGGs to children who are not yet able to read or write, do not possess advanced abilities to calculate payoffs, and only have a very limited attention span. It features the combination of haptic offline explanation, fully standardized audiovisual instructions, computerized choices based on touchscreens, and a suitable incentive scheme. Applying our experimental protocol to 129 German first-graders, we find that already 6-year-olds cooperate conditionally and that the relative frequency of different cooperati…
Contending legitimations
2010
Purpose“Contending legitimations” (Meyer and Scott) in cities – and especially multiple conflicting institutional pressures on decision makers – have not received sufficient accounting study. Therefore this paper aims to analyse the multiple institutional pressures on the performance measurement (PM) practices of two Finnish cities and answer why the developments and the coupling of budget or PM rules and routines were different in these relatively similar case cities.Design/methodology/approachIn this interpretive study, a comparative case setting (e.g. including several semi‐structured interviews) was used.FindingsContending legitimations affect the coupling of city budgeting and PM rules…
The FLuorescence EXplorer Mission Concept-ESA's Earth Explorer 8
2017
In November 2015, the FLuorescence EXplorer (FLEX) was selected as the eighth Earth Explorer mission of the European Space Agency. The tandem mission concept will provide measurements at a spectral and spatial resolution enabling the retrieval and interpretation of the full chlorophyll fluorescence spectrum emitted by the terrestrial vegetation. This paper provides a mission concept overview of the scientific goals, the key objectives related to fluorescence, and the requirements guaranteeing the fitness for purpose of the resulting scientific data set. We present the mission design at the time of selection, i.e., at the end of project phase Phase A/B1, as developed by two independent indus…
First Retrievals of ASCAT-IB VOD (Vegetation Optical Depth) at Global Scale
2021
Global and long-term vegetation optical depth (VOD) dataset are very useful to monitor the dynamics of the vegetation features, climate and environmental changes. In this study, the radar-based global ASCAT (Advanced SCATterometer) IB (INRAE-BORDEAUX) VOD was retrieved using a model which was recently calibrated over Africa. In order to assess the performance of IB VOD, the Saatchi biomass and three other VOD datasets (ASCAT V16, AMSR2 LPRM V5 and VODCA LPRM V6) derived from C-band observations were used in the comparison. The preliminary results show that IB VOD has a promising ability to predict biomass $(\mathrm{R}=0.74,\ \text{RMSE} =44.82\ \text{Mg}\ \text{ha}^{-1})$ , which is better …
