VisuMax®femtosecond laser for corneal refractive surgery
2008
Femtosecond lasers are increasingly present in ophthalmologic surgical theaters for a variety of reasons. These include faster and better visual outcomes, increased accuracy and predictability for corneal flap thickness in laser in situ keratomileusis procedures. Recent applications of modern femtosecond lasers have broadened the range of uses: keratoplasty, intrastromal segment insertion and even glaucoma and presbyopia surgery. This device profile provides an overview of the advantages of femtosecond lasers in ophthalmic surgery, paying special attention to the new VisuMax® femtosecond laser from Zeiss/Meditec.
The effects of post-pasture woody plant colonization on soil and aboveground litter carbon and nitrogen along a bioclimatic transect.
2013
Abstract: We investigated the effects of woody plant colonization of abandoned pastures on soil and litter organic carbon (C) stocks and nitrogen (N) content along a bioclimatic transect in a semi-arid environment (Sicily, Italy). Soil samples were taken in three successional stages (grazed pasture, shrubland, forest) within each of three bioclimates (supramediterranean - “supra”, mesomediterranean - “meso”, thermomediterranean - “thermo”). Organic C and N in litter and soil (0-10 cm and 10-30 cm depth) were determined, as well as soil bulk density. Especially at 0-10 cm depth, changes in C and N contents along successional stages differed among bioclimates. Soil organic carbon (SOC) stock …
Conservation value of forest plantations for bird communities in western Kenya
2008
Tree plantations of native and exotic species are frequently used to compensate for forest loss in the tropics. However, these plantations may support lower species diversity and different communities than natural forest. We therefore investigated bird communities in stands of natural forest, different types of tree plantations and secondary forest in Kakamega Forest, western Kenya. We compared birds differing in habitat specialisation, i.e. forest specialists, generalists, and visitors. We recorded significant differences in mean species richness and number of individuals among the different forest types. Stands of natural forest and plantations of indigenous tree species comprised more sp…
High seedling recruitment of indigenous tree species in forest plantations in Kakamega Forest, western Kenya
2009
Tree plantations are often used to compensate for the destruction and conversion of natural forests in the tropics. An important question is whether these plantations allow for the regeneration of indigenous tree species and are expected to transform into more natural forests in the future. To evaluate the potential of differently managed forest types for seedling recruitment of indigenous tree species we studied structural characteristics as well as tree and seedling communities in stands of natural forest, different types of tree plantations and secondary forest in Kakamega Forest, western Kenya. Forest types differed considerably in structural characteristics and tree composition with st…
Vida y muerte de Eliseo Gómez Serrano (1889-1939)
2012
Se estudia la trayectoria vital de Eliseo Gómez Serrano, su condena a muerte y ejecución por la dictadura de Franco. Fue catedrático de la Escuela Normal de Alicante en las primeras décadas del siglo XX, renovador de la pedagogía. Fue concejal por Izquierda Republicana en el Ayuntamiento de Alicante durante la Segunda república y desarrolló un plan ambicioso de escuelas públicas, fue diputado por Izquierda Republicana en 1936 y fusilado en 1939. We study the trajectory of Eliseo Gómez Serrano, his death sentence and execution by Franco's dictatorship. He was Professor at The the Escuela Normal of Alicante in the first decades of the twentieth century, renewing pedagogy. He was councilman fo…
Enseñanza de las ciencias : revista de investigación y experiencias didácticas
2021
This research focuses on teacher training in the Master's Degree in Secondary Educa- tion Teaching. The teaching guides of the specialisations of Biology and Geology and Physics and Che- mistry of the Master's Degree were analysed in order to know to what extent Education for Sustaina- bility (EfS) is present. Collaborative teams of teachers were arranged so as to promote the acquisition of competences in Sustainability among the training goals and to encourage resources and procedures for their effective achievement. This paper includes contributions that try to promote attention to EfS in Secondary School teacher training. Esta investigación se enmarca en la formación del profesorado en e…
Franciszkańska kuracja Serca Pana Jezusa w Gliwicach w latach 1925–1945
2016
Artykuł jest kontynuacją międzywojennej historii gliwickich franciszkanów i genezy powstania samodzielnej jednostki kościelnej w tzw. dzielnicy hutniczej, zamieszczonym w tomie 35 „Studiów Teologiczno-Historycznych Śląska Opolskiego” z 2015 r. Autor tym razem przybliża historię kuracji Serca Pana Jezusa w Gliwicach w latach 1925–1945. Od czasu jej ustanowienia gliwiccy franciszkanie prowadzili w tamtejszej dzielnicy hutniczej ożywioną pracę duszpasterską. Jej główne działania ukierunkowane były nie tylko na sprawowanie sakramentów, ale także na działalność społeczną wśród rodzin robotniczych. Po przybliżeniu statusu kuracji jako jednostki kościelnej, omówiono sylwetki duszpasterzy oraz wska…
A person-oriented approach to sport and school burnout in adolescent student-athletes: The role of individual and parental expectations
2017
Abstract Objectives The present study aimed to examine what kind of burnout profiles exist among student-athletes based on their sport and school burnout symptoms. Moreover, it was investigated whether athletes' expectations of success in sport and school, on the one hand, and parental expectations, on the other hand, were predictors of the likelihood of the athlete to show a certain profile, after taking into account the effects of gender, grade point average, type of sport, and level of competition. Design and methods The participants were 391 student-athletes (51% females) from six different upper secondary sport schools in Finland, and 448 parents (58% mothers). The athletes filled in q…
Symptoms of psychological ill-being and school dropout intentions among upper secondary education students : a person-centered approach
2020
A person-centered approach was used to identify the profiles of symptoms of psychological ill-being among Finnish upper secondary education students (N = 2889); to examine whether gender and educational track (i.e., academic or vocational) are associated with these profiles; and to investigate the role of profiles in school dropout intentions. Using latent profile analysis, one asymptomatic profile (normative, 79.2%) and three symptomatic profiles (internalizing symptoms, 9.1%; externalizing symptoms, 9.1%; and comorbid symptoms, 2.6%) were identified. Boys in the vocational track were overrepresented in the externalizing-symptoms profile, whereas girls in both tracks were overrepresented i…
What is important in history teaching? Student class teachers’ conceptions
2020
In Finland, history is taught in comprehensive schools at both primary and secondary levels. In primary schools, teachers are qualified class teachers who study one or two history courses during their teacher education. The amount of history taught in teacher education is limited, but student class teachers have studied history while at comprehensive school and general upper secondary school, and they have lived experience of historical cultures as members of different groups and communities. Thus, they have conceptions of what history teaching in school is, and what it should be. In this article, student class teachers’ conceptions of teaching history were examined using data (n=92) consi…
