An inverse problem for the minimal surface equation
2022
We use the method of higher order linearization to study an inverse boundary value problem for the minimal surface equation on a Riemannian manifold $(\mathbb{R}^n,g)$, where the metric $g$ is conformally Euclidean. In particular we show that with the knowledge of Dirichlet-to-Neumann map associated to the minimal surface equation, one can determine the Taylor series of the conformal factor $c(x)$ at $x_n=0$ up to a multiplicative constant. We show this both in the full data case and in some partial data cases.
Volume preserving mean curvature flows near strictly stable sets in flat torus
2021
In this paper we establish a new stability result for the smooth volume preserving mean curvature flow in flat torus $\mathbb T^n$ in low dimensions $n=3,4$. The result says roughly that if the initial set is near to a strictly stable set in $\mathbb T^n$ in $H^3$-sense, then the corresponding flow has infinite lifetime and converges exponentially fast to a translate of the strictly stable (critical) set in $W^{2,5}$-sense.
Technikum dla przodujących robotników w polskim systemie szkolnictwa zawodowego (1971-1982)
2018
W okresie PRL-u z inicjatywy PZPR powstało w 1971 r. technikum dla przodujących robotników. Uchwała nr 124 Rady Ministrów z dnia 1 lipca 1971 r. dała robotnikom możliwość zdobycia kwalifikacji zawodowych i uzyskania świadectwa dojrzałości po dwuletnim okresie edukacji. Takich szkół powstało ponad 30 w skali całego kraju. Do placówek tych kierowano wyróżniających się aktywną postawą społeczno-zawodową robotników, absolwentów zasadniczych szkół zawodowych. Celem ich było przygotowanie dla gospodarki narodowej dobrych fachowców, ale również aktywnych działaczy partyjnych. Rozpoczęły one pracę dydaktyczną we wrześniu 1971 r. Stworzono w nich bardzo dobre warunki uczenia się dorosłym uczniom, za…
ICT and Curriculum Change
2005
The change towards the information society implies that many countries have to change their curricula, because students need to develop competencies that are not addressed in the traditional curricula. A case study approach was applied to examine curriculum changes in ICT-supported pedagogical practices from 28 countries. The analysis focused on curriculum content and goals of the ICT-supported pedagogical practices, how these aims were implemented in practice and which outcomes for students and teachers could be observed. The results showed that the curriculum content often was not new but rather was delivered in a different way. Many ICT-supported pedagogical practices strove to realize n…
Teaching competences in Secondary Education : analysis of teachers’ profiles
2014
This paper reports some of the findings from a study that aimed to analyse the importance attributed by secondary education teachers from the province of Castellón (Spain) to teaching competencies and to establish professional profiles from their responses. The survey was based on a purposely designed questionnaire answered by a representative sample of 136 secondary teachers from Castellón, representing 23 school departments. From an analysis of the responses we identified three professional profiles based on the importance that teachers attribute to a range of competencies; although all the competencies were valued highly, we found that teachers still consider the traditional delivery of …
Cyber security training in Finnish basic and general upper secondary education
2023
Cyber security in Finland is part of other areas of comprehensive security, as digital solutions multiply in society and technologies advance. Cyber security is one of the primary national security and nationaldefense concerns. Cyber security has quickly evolved from a technical discipline to a strategic concept. Cyber security capacity building can be measured based on the existence and number of research and developments, education and training programs, and certified professionals and public sector agencies.Cybersecurity awareness and the related civic skills play an increasingly important role as our societies become more digitalized. Improving citizens' cyber skills through education i…
Guano-related phosphate-rich minerals in European caves
2019
International audience; Guano is a typical deposit found in caves derived from the excretions of bats and in minor cases of birds. These organic deposits decompose and form a series of acid fluids and gases that can interact with the minerals, sediments, and rocks present in the cave. Over sixty phosphates are known and described from caves, but guano decay also often leads to the formation of nitrates and sulfates. In this study twenty-two European caves were investigated for their guano-related secondary minerals. Using various analytical techniques, seventeen phosphates, along with one sulfate (gypsum), were recognized as secondary products of guano decay. Among those minerals, some are …
A phenomenological view of pictures in teaching and a novel method for analysing them
2014
In this paper a novel method for analysing the content and teaching potential of pictures is presented. It is the four-field method, which is based on phenomenological thoughts about human experience, which combines factual knowledge with emotions and personal and social meanings. A biological example is given. Around this idea a course unit for using pictures in science teaching was organized. It was used in the training of both primary and secondary level teachers. From picture analysis the course unit proceeds to planning the use of pictures in teaching. A classification of the teaching functions of pictures is presented.
Educación artística : revista de investigación
2019
Resumen: En este artículo se presenta una experiencia artística realizada en diez centros de enseñanza secundaria de L’Horta Nord y Camp de Morvedre (València) sobre los procesos de construcción identitaria mediante actitudes artísticas contemporáneas, en este caso, a través del videoarte. Utilizando la Investigación educativa basada en las artes (Arts Based Educational Research) se ha llevado a término la realización y posterior análisis interpretativo de todas las producciones videográficas fundamentadas en el autorretrato tradicional, por tanto, han conformado unos resultados muy interesantes que inducen a reflexionar sobre la utilización y desarrollo de estos nuevos géneros contemporáne…
Molecular evolution of aphids and their primary (Buchnera sp.) and secondary endosymbionts: Implications for the role of symbiosis in insect evolution
2001
Aphids maintain an obligate, endosymbiotic association with Buchnera sp., a bacterium closely related to Escherichia coli. Bacteria are housed in specialized cells of organ-like structures called bacteriomes in the hemocoel of the aphid and are maternally transmitted. Phylogenetic studies have shown that the association had a single origin, dated about 200-250 million years ago, and that host and endosymbiont lineages have evolved in parallel since then. However, the pattern of deepest branching within the aphid family remains unsolved, which thereby hampers an appraisal of, for example, the role played by horizontal gene transfer in the early evolution of Buchnera. The main role of Buchner…
