A geometrical criterion for nonexistence of constant-sign solutions for some third-order two-point boundary value problems

2020

We give a simple geometrical criterion for the nonexistence of constant-sign solutions for a certain type of third-order two-point boundary value problem in terms of the behavior of nonlinearity in the equation. We also provide examples to illustrate the applicability of our results.

Julien : les années parisiennes

2009

This article intends to scrutinize in what ways Julian’s stay in Gaul as a Caesar were decisive in Julian’s political and military education, and whether a specific ruling style and manner may be detected in the Parisian years of Julian’s government. Relying on a critical analysis of the documentation (Julian himself, Mamertinus, Ammianus, Libanios), the author examines the military and civilian aspects of Julian’s training as an apparently inexperienced ruler but quick learner. She carries out a prosopographical study of the Caesar’s circle and the administrative staff which was then on duty, combining friendly and hostile persons. Gaul offered him a training ground and he became even the …

Progetto della chiesa di San Giacomo Apostolo a Ferrara

2012

Il progetto di Andrea Sciascia, per il complesso parrocchiale di San Giacomo Apostolo in Ferrara, terzo classificato nell’ultima edizione (sesta) dei concorsi promossi dalla CEI, interviene in un’area periferica della città, interessata da profonde trasformazioni e dall’inserimento di elementi infrastrutturali viari. La superficie di circa un ettaro, dove è presente l’originario e minuto complesso parrocchiale di San Giacomo a Ferrara, è coinvolta in profonde trasformazioni urbane fra le quali spicca un’ampia rotatoria. La perentorietà del rondeau si confronta, nella proposta di progetto, con due figure dalla geometria nitida: un rettangolo tendente al quadrato, la chiesa, e una figura allu…

Study of the performance of a resolution criterion to characterise complex chromatograms with unknowns or without standards

2017

The search for best conditions in liquid chromatography is routinely carried out with information provided by chemical standards. However, sometimes there are samples with insufficient knowledge about their chemical composition. In other cases, identities of the components are known, but there are no standards available, and in other cases the identities of peaks in chromatograms taken under different conditions are ambiguous. Most resolution criteria used to measure separation performance cannot be applied to these samples. In this work, a global resolution function valid for all situations was developed based on automatic measurements of peak prominences (area fraction exceeding the line …

Argumentation Skills as Prerequisites for Collaborative Learning Among Finnish, French and English Secondary School Students.

2005

International audience; Argumentation skills of secondary school students were evaluated in Finland (n = 290), France (n = 54), and England (n = 41). The data were collected from 4 tasks comprising 7 variables. The results indicated that most of the students had correctly justified arguments and conclusions, and composed clear claims and relevant arguments. However, many students had difficulties in recognising the main claim and arguments for it in an expository text, and in commenting analytically on an argumentative text. Thus the students possessed the prerequisites for argumentative reasoning and writing but need further practice in analytical and critical reading.

Testing the shape-similarity hypothesis between partide-size distribution and water retention for sicilian soils

2012

Application of the Arya and Paris (AP) model to estimate the soil water retention curve requires a detailed description of the particlesize distribution (PSD) but limited experimental PSD data are generally determined by the conventional sieve-hydrometer (SH) method. Detailed PSDs can be obtained by fitting a continuous model to SH data or performing measurements by the laser diffraction (LD) method. The AP model was applied to 40 Sicilian soils for which the PSD was measured by both the SH and LD methods. The scale factor was set equal to 1.38 (procedure AP1) or estimated by a logistical model with parameters gathered from literature (procedure AP2). For both SH and LD data, procedure AP2 …

La diversificación y consolidación de los servicios sociales para las personas mayores en España y Suecia

2011

La información sobre los servicios públicos para las personas mayores a menudo se limita a la atención residencial y a la ayuda a domicilio. Sin embargo, estos servicios básicos son en muchos países complementados o sustituidos por otros servicios de menor envergadura, como el transporte, comidas a domicilio, teleasistencia y centros de día. Esta diversificación partió de un racionamiento de los servicios para lograr una asignación más racional de los recursos y, si se podía, un menor gasto. En este trabajo se utilizan diversos datos sobre estos servicios en España y Suecia. Cuando se consideran todos los cuidados, la cobertura de atención es mucho mayor que si sólo se contemplan los servic…

The Southern Annular Mode seen through weather regimes

2012

This article investigates the prominent features of the Southern Hemisphere (south of 20°S) atmospheric circulation when extracted using EOF analysis and a k-means clustering algorithm. The focus is on the southern annular mode (SAM), the nature of its recent trend, and the zonal symmetry of associated spatial patterns. The study uses the NCEP–Department of Energy Atmospheric Model Intercomparison Project II Reanalysis (NCEP-2) (period 1979–2009) to obtain robust patterns over the recent years and the Twentieth Century Reanalysis Project (period 1871–2008) to document decadal changes. Also presented is a comparison of these signals against a station-based reconstruction of the SAM index an…

Influence of clouds on the spectral actinic flux density in the lower troposphere (INSPECTRO): overview of the field campaigns

2008

Ultraviolet radiation is the key factor driving tropospheric photochemistry. It is strongly modulated by clouds and aerosols. A quantitative understanding of the radiation field and its effect on photochemistry is thus only possible with a detailed knowledge of the interaction between clouds and radiation. The overall objective of the project INSPECTRO was the characterization of the three-dimensional actinic radiation field under cloudy conditions. This was achieved during two measurement campaigns in Norfolk (East Anglia, UK) and Lower Bavaria (Germany) combining space-based, aircraft and ground-based measurements as well as simulations with the one-dimensional radiation transfer model UV…
