Solid–Liquid Suspensions in Top-Covered Unbaffled Vessels: Influence of Particle Size, Liquid Viscosity, Impeller Size, and Clearance
2014
Particle suspension in liquids is a unit operation commonly encountered in the process industry. Although it is usually carried out in baffled stirred tanks, there are some specific applications where the presence of baffles may be undesirable. In the present work solid-liquid suspensions are investigated in a radially stirred unbaffled tank provided with a top cover. The minimum impeller speed at which all solid particles get suspended (Njs) and the relevant power requirements (Pjs) are assessed. The dependence of these two parameters on physical properties (liquid viscosity, particle concentration, and size) and system geometrical configurations (impeller diameter and clearance) is invest…
Generating and Instantiating Abstract Workflows with QoS User Requirements
2017
The growing availability of services accessible through the network makes it possible to build complex applications resulting from their composition that are usually characterized also by non-functional properties, known as Quality of Service (QoS). To exploit the full potential of service technology, automatic QoS-based composition of services is crucial. In this work a framework for automatic service composition is presented that relies on planning and service negotiation techniques for addressing both functional and non-functional requirements. The proposed approach allows for dynamic service composition and QoS attributes, and it can be applied when services are provided in the contest …
User requirements and resource control for cooperative multimedia applications
1997
The spread of distributed multimedia applications is setting forth a new set of challenges in the management of host and network resources for guaranteeing Quality of Service (QoS). When the multimedia applications compete for resources as in the case of a cooperative multimedia environment, the management task becomes even more difficult. In this work, we first discuss QoS for multimedia applications. We then present the architectural and implementation details of a Cooperative Multimedia Environment (CME) made up of Cooperative Multimedia Applications (COMMA), one for each user. A COMMA presents a user with a single interface that allows him to invite other users to a cooperative session,…
Ecological role of mycotoxins produced by Fusarium graminearum : consequences of the presence of deoxynivalenol (DON) in crop residues on the soil mi…
2012
Fusarium graminearum is a plant pathogenic fungus, causing devastating disease “Fusarium head blight” (FHB) in cereals including wheat and maize. It also contaminates the grains with mycotoxins including deoxynivalenol (DON) which are toxic to human and animals. This disease has resulted in the serious losses in grain yield and quality. We established through a first bibliographic review that during off season fungus survives saprophytically on the crop residues (ecological habitat) and serves as primary inoculum for the next season crop. However, we noticed also that the literature was poor about the role mycotoxins could play in the establishment of F. graminearum in such a habitat. The m…
Developing a framework for designing humanitarian blockchain projects
2021
International audience; Blockchain technology promises to improve the efficiency, transparency, and accountability of humanitarian operations. Yet at the same time, especially the humanitarian context with its characteristic volatility poses unique challenges to any technology. Most prominent are the humanitarian principles that are fundamental to humanitarian operations. These ethical principles are set to protect the most vulnerable populations. Designing blockchain projects in the humanitarian context therefore requires a systematic framework that helps humanitarians make critical choices.While some design instructions can be found for commercial applications, the humanitarian context re…
DIVERSITY AND THE MAIN ECOLOGICAL REQUIREMENTS OF THE EPIGEIC SPECIES OF FOREST ECOSYSTEMS IN THE SIBIU COUNTY, IN THE YEARS 2013-2014
2014
Epigeous insects in the “Dumbrava Sibiului” oak forest were captured between 2013-2014. From April to September in each year. 12 traps were installed in a circle 147 individuals collected belonged to 28 species and 6 families: Carabidae – 14 species (50.0%), 187 individuals (77.37 %), Staphylinidae – 7 species (25.0 %), 15 individuals (6.17 %), Silphidae – 3 species (10.72 %), 29 individuals (11.93 %), Elateridae – 1 species (3.51 %), 1 individual (0.41 % ), Scarabaeidae – 2 species (7.14 %), 8 individuals (3.29 %), Forficulidae – 1 species (3.51 %), 2 individuals (0.82 %)). Also, we presented in tables the ecological requirements of the species of Carabidae collected, the variation of thei…
Mobility and transition of pedagogical expertise in Finland
2015
Mobility and transition of pedagogical expertise in Finland is a publication based on the project “Mobility among pedagogical experts”, which was funded by the European Social Fund. The project was carried out in 2010–2013 in collaboration with the Finnish Institute for Educational Research, Finnish National Board of Education and the Vocational Teacher Education College, Jyväskylä University of Applied Sciences. The publication gives an overall view of the teacher mobility and transition in the Finnish education system and discusses the key findings from the report on Mobility among pedagogical experts. Data for the above-mentioned project was collected by an online questionnaire (n = 4500…
Hypotheses engineering : first essential steps of experiment-driven software development
2019
Recent studies have proposed the use of experiments to guide software development in order to build features that the user really wants. Some authors argue that this approach represents a new way to develop software that is different from the traditional requirement-driven one. In this position paper, we propose the discipline of Hypotheses Engineering in comparison to Requirements Engineering, highlighting the importance of proper handling hypotheses that guide experiments. We derive a set of practices within this discipline and present how the literature has tackled them up to now. Finally, we propose a set of research questions that could guide future work towards helping practitioners. …
Gir boplikt lavere boligpriser?
2020
Siden 1974 har norske kommuner hatt adgang til å innføre boplikt for eiendommer som er eller har vært i bruk som helårsbolig. Ordningen har helt siden den ble innført, vært svært omstridt. Vi undersøker hvordan boplikt påvirker boligprisene. Geografisk avgrenser vi oss til kystkommuner på Sørlandet, der mange som har sin faste bopel andre steder i landet, etterspør fritidsbolig. Uten boplikt kan helårsboliger bli kjøpt opp for å bli brukt som fritidsboliger. Den empiriske analysen, basert på data fra fire sørlandskommuner, hvorav den største kommunen, Arendal, opphevet boplikten i 2014, viser at prisene i kystsonen økte da boplikten ble opphevet.
Overview of methods used to evaluate the adequacy of nutrient intakes for individuals and populations
2009
The objective of the present paper is to review the methods of measuring micronutrient intake adequacy for individuals and for populations in order to ascertain best practice. A systematic review was conducted to locate studies on the methodological aspects of measuring nutrient adequacy. The results showed that for individuals, qualitative methods (to find probability of adequacy) and quantitative methods (to find confidence of adequacy) have been proposed for micronutrients where there is enough data to set an average nutrient requirement (ANR). If micronutrients do not have ANR, an adequate intake (AI) is often defined and can be used to assess adequacy, provided the distribution of dail…
