Explicit relationships for optimal designing rectangular microirrigation units on uniform slopes: The IRRILAB software application
2018
Abstract Many attempts have been made to provide easy tools for designing microirrigation units. However, most of these have dealt with numerical solutions, which require many trial-and-error attempts and time-consuming iterations, performed by applying the basic hydraulic equations from the manifold to the end of both the downhill and the uphill sides of the laterals. Recently, analytical procedures to optimally design paired drip laterals on uniform slopes were proposed, providing readily obtainable results and energy saving. Although these analytical solutions can be practically applied, they only make it possible to design a one-lateral unit; to be really interesting for practical appli…
Optimal design of tuned liquid column dampers for seismic response control of base-isolated structures
2017
In this paper, the use of a tuned liquid column damper (TLCD) as a cost-effective means to control the seismic response of a base-isolated structure is studied. A straightforward direct approach for the optimal design of such a device is proposed, considering a white noise model of the base excitation. On this base, a direct optimization procedure of the TLCD design parameters is performed and optimal design charts are presented as a ready-to-use practical design tool. Comparison with the optimal parameters obtained considering a classical iterative statistical linearization technique proves the reliability of the proposed approach. The performance of the base-isolated TLCD-controlled struc…
Organizing for What: Job Rotation as an Organizational Development Strategy or as an Organizational anti-Corruption Tool?
2021
The purpose of this article is to understand if Job Rotation (JR)/Organizational Development (OD)-oriented strategies are compatible with JR strategies to curb Organizational Corruption (OC), as these strategies seem to indicate an apparent contradiction. To this end, the paper is structured as follows. Firstly, the main points of JR-Theory in organizational studies are displayed. Subsequently, JR-Theory in organizational anti-corruption is more deeply explored. At the end of the review, the research question is proposed in the methodological section. The two sections after that are devoted to answering this question. The first of which examines the laws and documents of the National Anti-C…
Fusarium wilt of cyclamen : early detection and biocontrol
2016
Fusarium wilt of cyclamen is one of the most damaging diseases of cyclamen. The causal agent, Fusarium oxysporum f. sp. cyclaminis, is a soil-borne fungus. Losses can reach more than 50 % of the production. Several methods of control are available, but none of them offer an efficient and environmentally friendly solution. In this context, a project was developed in collaboration with the French institute of horticulture, Astredhor, which represents the producers, the INRA of Dijon, for its expertise on F. oxysporum and the company Agrene for its expertise in biological control. The project has two goals: i) design a molecular marker specific of Fusarium oxysporum f. sp. cyclaminis allowing …
Des outils moléculaires toujours plus multifonctionnels pour l’étude de structures alternatives d’acides nucléiques.
2022
G-Quadruplexes (G4) are non-canonical secondary structure found throughout the genome and transcriptome in guanine rich sequences. Their involvement in biologically relevant processes (telomeres maintenance, transcription and translation) has been demonstrated, yet their role is still not fully elucidated. To investigate their role, we focus on the development of biomimetic molecular tools that could be used either to isolate G4 by new generation sequencing techniques or visualize them directly in cell. This class of molecular tools (TASQ: Template Assembled Synthetic Quartet) is composed by four guanine moieties linked to a central template thanks to spacers of different chemical nature. I…
Measurement of Upsilon production in collisions at root s=2.76 TeV
2014
The production of Υ(1S) , Υ(2S) and Υ(3S) mesons decaying into the dimuon final state is studied with the LHCb detector using a data sample corresponding to an integrated luminosity of 3.3pb-1 collected in proton–proton collisions at a centre-of-mass energy of s=2.76 TeV. The differential production cross-sections times dimuon branching fractions are measured as functions of the Υ transverse momentum and rapidity, over the ranges pT<15 GeV/ c and 2.0<y<4.5 . The total cross-sections in this kinematic region, assuming unpolarised production, are measured to be σpp→Υ(1S)X×BΥ(1S)→μ+μ-=1.111±0.043±0.044nb,σpp→Υ(2S)X×BΥ(2S)→μ+μ-=0.264±0.023±0.011nb,σpp→Υ(3S)X×BΥ(3S)→μ+μ-=0.159±0.020±0.…
Social information use by predators : expanding the information ecology of prey defences
2022
Social information use is well documented across the animal kingdom, but how it influences ecological and evolutionary processes is only just beginning to be investigated. Here we evaluate how social transmission may influence species interactions and potentially change or create novel selection pressures by focusing on predator-prey interactions, one of the best studied examples of species coevolution. There is extensive research into how prey can use social information to avoid predators, but little synthesis of how social transmission among predators can influence the outcome of different stages of predation. Here we review evidence that predators use social information during 1) encount…
Development and validation of the Brief Parental Burnout Scale (BPBS).
2021
Since parental burnout can have detrimental consequences for parents, couples, and children, easy-to-use, reliable, and valid practical tools for the early detection of parental burnout are required. We developed and validated a brief scale to identify burned-out parents and parents at burnout risk. In Study 1, we developed the 5-item Brief Parental Burnout scale (BPBs) based on the gold standard measure of parental burnout, the Parental Burnout Assessment (PBA). We applied Item Response Theory Graded Response Model (GRM) analyses on the data of 1,725 Finnish parents. Compared against the PBA total score, the five selected items showed both high sensitivity and specificity in screening pare…
An integrated multiobjective design tool for process design
2006
An integrated multiobjective design tool has been developed for chemical process design. This tool combines the rigorous process calculations of the BALAS process simulator and the interactive multiobjective optimization method NIMBUS. With this design tool, the designer can consider several conflicting performance criteria simultaneously. The interactive nature of this tool allows the designer to learn about the behavior of the problem. To illustrate the possibilities of this design tool, two case studies are considered. One of them is related to paper making while the other one is related to power plants.
A Toolbox of Phenomenological Methods
2009
In addition to a large number of misrepresentations of phenomenology,1 one can see an increasing interest in phenomenology among cognitive scientists and analytic philosophers. It is the method of phenomenology from which one expects to shed some light on the problem of consciousness. How does this approach work? What are the specific tools of phenomenology? Explanations as well as critical discussions of phenomenological methods are scattered across the literature. Moreover, the sometimes misleading or impenetrable terminology of classical phenomenology blocks easy understanding. The language of phenomenology may be an important reason why the working cognitive scientist who may be ready t…
