Evolutionary implications of intron-exon distribution and the properties and sequences of the RPL10A gene in eukaryotes.

2013

The RPL10A gene encodes the RPL10 protein, required for joining 40S and 60S subunits into a functional 80S ribosome. This highly conserved gene, ubiquitous across all eukaryotic super-groups, is characterized by a variable number of spliceosomal introns, present in most organisms. These properties facilitate the recognition of orthologs among distant taxa and thus comparative studies of sequences as well as the distribution and properties of introns in taxonomically distant groups of eukaryotes. The present study examined the multiple ways in which RPL10A conservation vs. sequence changes in the gene over the course of evolution, including in exons, introns, and the encoded proteins, can be…

Zr, Hf and REE distribution in river water under different ionic strength conditions

2018

International audience; The Platani River flowing in south-central Sicily, interacting with evaporite rocks, generates a wide range of ionic strength in the water catchment from 0.1 to 5.0 mol kg−1. We sampled 38 river sites and analysed the composition for the dissolved fraction filtered through 0.45 μm, the truly dissolved fraction obtained through ultrafiltration (10 kDa) and the relative included colloidal fraction.This study was focused on the recognition of Zr, Hf and REE behaviour under changing ionic strength conditions, since this is one of parameters responsible for colloid stability in natural waters. In turn, this phenomenon leads to REE release from the colloidal fraction and t…

CHEMICAL AND BOTANICAL CHARACTERIZATION OF A ROSMARINUS OFFICINALIS L. BIOTYPE FROM SICILY

2006

Rosemary (Rosmarinus officinalis L.) is widely cultivated all over the world as ornamental and aromatic plant. Today, the interest towards its cultivation is strongly arising, due to the many biological activities exerted by the essential oil extracted from its leaves and flowers. Which compounds confer to Rosemary's essential oil its properties is still unclear, but it seems likely that these effects must be attributed to a mixture of different principles, acting contemporarily and synergically. The diverse composition of the essential oils of Rosemary's ecotypes coming from different geographical areas could be the reason of their various level of activity. With the aim of obtaining furth…

Immateriaalioikeuksien esiintyminen SIGCSE-konferenssien julkaisuissa

2017

Immateriaalioikeuksiin liittyvien sääntöjen ja haasteiden kohtaaminen on arkipäiväistynyt opetuksessa. Opiskelijat saavat suurimman osan valmiuksistaan immateriaalioikeuksien noudattamiseen ja ammatillisuuteen koulutuksestaan. Immateriaalioikeustietämys on nostanut merkitystään erityisesti tietotekniikan ammattilaisten vaatimuksena. Aihe on ajankohtainen ja opetussuunnitelmassa usein vähäiselle huomiolle jäävä. Opetuksen kehityksen suunta on opiskelijoiden omaa luovuutta tukevien ympäristöjen tehokkaampi hyödyntäminen, mutta niiden käyttö usein edellyttää aiempaa parempaa immateriaalioikeustietämystä. Tässä työssä selvitettiin, miten paljon ja millä tavoin immateriaalioikeuksia koskevat asi…

Enhancing Digital Skills of Early Childhood Teachers Through Online Science, Technology, Engineering, Art, Math Training Programs in Estonia

2022

Teacher professional development programs, including mid- and long-term Science, Technology, Engineering, Art, Math (STEAM) courses, have recently moved from in person learning at university premises to an online environment. Whether it is a temporary change in learning methods caused by the COVID-19 restrictions or whether it will become a new normal is currently under discussion in many teacher training institutions around the world. The aim of this study was to design and implement time- and money-saving synchronous online teacher training format for conducting co-design courses for early childhood teachers in the theme of STEAM integrated learning activities. Based on Tallinn University…

The essential oil composition of Centaurea immanuelis-loewii Degen growing wild in Bulgaria and chemotaxonomy of section Acrocentron

2021

In the present study, the chemical composition of the essential oil from aerial parts of the Balkan endemic, Centaurea immanuelis-loewii Degen (sect. Acrocentron, Asteraceae), collected in Bulgaria was evaluated by GC-MS. The main components of the oil were β-caryophyllene (23.2%), germacrene D (13.7%) and caryophyllene oxide (12.4%). Furthermore, a complete literature review on the composition of the essential oils of all the other taxa of Centaurea, belonging to section Acrocentron, studied so far, was performed and the chemotaxonomical variations in the composition of the essential oils is discussed.
