Properties of zeros of solutions to third order nonlinear differential equations

2013

We investigate the behavior of zeros of solutions to the certain type of third order nonlinear differential equations. We show that the behavior of zeros may be rather different and depend on the nature of nonlinearity in the equation. Main results in the paper are illustrated with a number of examples.

Statistical Approximation of Fourier Transform-IR Spectroscopy Data for Zinc White Pigment from Twentieth-Century Russian Paintings

2017

We present a statistical model for approximation of experimental Fourier transform-IR spectroscopy (FTIR) data for paint samples from paintings of different ages. The model utilizes random variations in some parameters (initial ageing rate, degree of change in ageing rate and time at which the change occurs). We determine the parameters characterizing variation in the paint composition and the storage conditions for the paintings. The numerical calculation is qualitatively consistent with the experimental data. In the proposed model, changes in the initial composition of the paint and the storage conditions make about the same contribution to the experimentally observed scatter in the data …

Metaforu lietojums rakstos par ''Brexit''

2018

Pētījumā aplūkots metaforu lietojums saistībā ar Apvienotās Karalistes izstāšanos no Eiropas Savienības – mūsdienās tas ir vēl nebijis politisks lēmums. Pētījuma mērķis bija noteikt, cik bieži metaforas tiek lietotas dažādos ziņu rakstos par “Brexit” un kādas ir galvenās metaforu funkcijas. Kā empīriskā izpētes metode darbā izmantota diskursa analīze. Tās rezultāti atklāja, ka rakstos bieži tiek lietotas no fiziskām parādībām aizgūtas metaforas, lai izskaidrotu sarežģītos “Brexit” procesus. Turklāt metaforas tiek izmantotas, lai paustu kritiku, norādot, ka Apvienotajai Karalistei nevajadzētu izstāties no Eiropas Savienības. Jāsecina, ka metaforām ziņu diskursā ir dažādas funkcijas un tās īp…

Relationship between trophic state and plankton community structure in 21 Sicilian dam reservoirs

1994

The relationship between the trophic state of 21 Sicilian dam reservoirs and their taxonomic community structure of phytoplankton (87 taxa) as well as zooplankton (45 taxa) have been examined by means of cluster analysis performed using annual average biomass values. The phytoplankton community structure was closely connected with the trophic state of the reservoirs, whereas the zooplankton community structure was related to hydrological regimes peculiar to the individual water bodies and not to the trophic state. © 1994 Kluwer Academic Publishers.

Capital social como estructura de análisis : validaciones en perspectivas de género y territorio

2005

Este artículo estudia las categorías analíticas del concepto de capital social desde una perspectiva de género. Cómo se produce, se distribuye y quienes son los beneficiarios de capital social está siendo objeto de un debate abierto dentro de diferentes disciplinas. En geografía, capital social se puede configurar como una herramienta de interpretación básica, sobre todo en el estudio de los trabajos de mujeres en áreas rurales de montaña. El artículo analiza las aportaciones de cuatro de losmmás importantes teóricos del concepto, Pierre Bourdieu, James Coleman, Robert Putnam y Nan Lin, con el objetivo de hacer una relectura de capital social que ayude a abrir un debate sobre cómo identific…

La mesure de l'efficacité scolaire par la méthode de l'enveloppe : test des filières alternatives de recrutement des enseignants dans le cadre du pro…

2009

Data envelopment and school effectiveness: contract teachers' efficiency compared to civil servants in the Education for all process) In the context of EFA process, countries, in general the most depressed LDC, both constrained by scarcity of funding and urgency for expanding school access have set up new tracks for teacher recruitment on annually renewable contracts. Those teachers are often not professionally trained in regards with traditional pedagogical curricula. They receive much lower salaries than regular civil service teachers. This has been a controversial policy, but there is very limited evidence on the effectiveness or failure of contract teachers in improving student learning…
