Sugar moiety has a direct influence on the secondary structure and properties of sturgeon gonadotropin

2009

Sugar moiety has a direct influence on the secondary structure and properties of sturgeon gonadotropin Sturgeon Acipenser güldenstädti Br. gonadotropic hormone (GTH) β-subunit (β-GTH) was selectively chemically deglycosylated (dg) by anhydrous hydrogen fluoride and trifluoromethane sulfonic acid. Two dgβ-GTH molecular forms retaining 35% (dgβ-GTH1) and 13% (dgβ-GTH2) of their initial carbohydrates were obtained. Investigation of the reassociated α-β hybrid dimers (recombinants) α-GTH+dgβ-GTH1 and α-GTH+dgβ-GTH2 showed that the immunoreactivity with antiserum raised against standard GTH dropped by 22.5%. Hybrid dimers were recognised by the standard GTH antibodies, which indicated that the s…

Puheviestintätaitojen arviointi : näkökulmia lukiolaisten esiintymis- ja ryhmätaitoihin

2003

Vuorovaikutustaidot ovat keskeinen osa yleissivistävän koulutuksen tuottamaa viestintäsivistystä. Lukiolaiset ovat myös voineet osallistua valtakunnalliseen puheviestinnän päättökokeeseen vuodesta 2000 lähtien. Yliassistentti Tarja Valkosen väitöstutkimus on ensimmäinen laaja-alainen selvitys siitä, miten lukiolaisten esiintymis- ja ryhmätaitoja ohjataan oppimaan ja arvioidaan. Se osoittaa, että päättökoe ja sen kehittelytyö ovat vaikuttaneet myönteisesti lukion puheviestinnän opetukseen. Lukiolaisten puheviestintätaitojen taso osoittautui tutkimuksessa keskimäärin hyväksi. Puhe-esitysten rakentamisen ja johdonmukaisen esittämisen taidot sekä esiintymisvarmuus kaipaavat kuitenkin kehittämis…

Quasiconformal geometry and removable sets for conformal mappings

2020

We study metric spaces defined via a conformal weight, or more generally a measurable Finsler structure, on a domain $\Omega \subset \mathbb{R}^2$ that vanishes on a compact set $E \subset \Omega$ and satisfies mild assumptions. Our main question is to determine when such a space is quasiconformally equivalent to a planar domain. We give a characterization in terms of the notion of planar sets that are removable for conformal mappings. We also study the question of when a quasiconformal mapping can be factored as a 1-quasiconformal mapping precomposed with a bi-Lipschitz map.

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 …

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…

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’s the name of the game? : Historiallinen empatia ja pelillisyys historian opetuksessa

2019

Historian opetuksen yhteydessä on viimeisten kahden vuosikymmenen aikana puhuttu erityisesti opetuksen suuntaamisesta sisältöjen opettamisesta historian taitojen ja demokraattisena kansalaisena toimimisen suuntaan. Tavoitteet edellyttävät myös käytäntöjen muuttumista. Tässä artikkelissa tarkastellaan lukion historian opetusta opetuskokeilun kautta. Kokeilussa hyödynnettiin pelillisyyttä sekä historiallista empatiaa. Kahdeksan tuntia kestäneen pelin aikana opiskelijoiden tehtävänä oli konstruoida tietoa vuonna 1957 tapahtuneesta ampumavälikohtauksesta presidentin kesäasunnolla Kultarannassa. Aineisto kerättiin opetuskokeilun yhteydessä (N = 30 lukiolaista) kyselylomakkeen ja haastattelun avu…

Metal ions modulate thermal aggregation of betalactoglobulin: a join chemical and physical characterization

2014

Abstract Molecular basis of the role played by Cu 2 + and Zn 2 + ions during the thermal aggregation processes of beta-lactoglobulin (BLG) was studied by using a joint application of different techniques. In particular, Raman spectroscopy was very useful in identifying the different effects caused by the two metals at molecular level (i.e. changes in His protonation state, disulfides bridge conformation, and micro-environment of aromatic residues), evidencing the primary importance of the protein charge distribution during the aggregation process. Both metal ions are able to act on this factor and favor the protein aggregation, but Zn 2 + is able to alter the natural conformational state of…
