La valorizzazione della flora spontanea attraverso lo studio di nuovi biopesticidi: Artemisia arborescens L.
2013
A seguito del loro processo evolutivo, numerose specie vegetali hanno orientato il loro metabolismo secondario verso la produzione di molecole complesse, dotate in molti casi di un’evidente funzione protettiva nei confronti delle avversità (insetti, funghi, virus, ma anche altre piante in competizione). Lo studio e la valorizzazione di queste molecole, da utilizzare nell’ambito delle tecniche di difesa sostenibile ed integrata con l’obiettivo di ottenere una riduzione dell’impiego di prodotti sintetici ad elevato impatto ambientale, costituiscono oggi una tematica di ricerca di grande interesse. All’interno della flora spontanea mediterranea, molto rappresentata è Artemisia arborescens L., …
Subjektiivinen tuntemus liikunnan kuormittavuuden ohjaajana inaktiivisilla naisilla : kuormittavuuden määrittäjinä syke ja askelfrekvenssi
2010
Tutkimuksen päätarkoituksena oli pilottitutkimuksen muodossa selvittää, minkälaisia fyysistä rasitusta mittaavia arvoja saadaan vähän liikuntaa harrastavilla naisilla, kun fyysisen rasituksen kuormittuneisuutta ohjaa etukäteen annettu ohjeistus subjektiivisesta tuntemuksesta kolmella eri kuormitustasolla. Objektiivisina mittareina tutkimuksessa käytettiin sykemittaria sekä askelfrekvenssiä. Lisäksi selvitettiin painoindeksin vaikutusta saatuihin arvoihin. Tutkimusaineisto koostui 13 Jyväskylän yliopiston opiskelijasta. Tilastollinen analyysi suoritettiin SPSS- ohjelmalla. Muuttujia, niiden riippuvuussuhteita sekä voimakkuuksia arvioitiin Pearsonin korrelaatiokertoimen sekä hajonta- ja boxpl…
Volatile components of Centaurea bracteata and C. pannonica subsp. pannonica growing wild in Croatia.
2010
This paper reports on the volatile components of oils from the aerial parts (CBA) and roots (CBR) of Centaurea bracteata Scop. and aerial parts of C. pannonica (Heuffel) Simonkai subsp. pannonica (CPA), two Asteraceae growing wild in Croatia. The volatile components, obtained by hydrodistillation, were determined by GC-MS analysis. The yields (w/w) of the dried oils were 0.10% (CBA), 0.22% (CBR) and 0.09% (CPA), respectively. A total of 91 compounds were identified accounting for 91.1%, 93.3% and 87.9% of the total oil for CBA, CBR and CPA, respectively. All the samples were characterized mainly by hydrocarbons (7.1-34.1%), fatty acids (9.7-45.9%), and oxygenated sesquiterpenes (15.2-16.6%)…
Chemical composition of the essential oil of Centaurea sicana and C. giardinae growing wild in Sicily
2008
The essential oils of Centaurea sicana (S) and C. giardinae (G) were studied by GC and GC-MS. Thirty constituents for S, representing 81.5% of the total oil, and 24 compounds for G (94.2% of the total) were identified. The oils were rich in sesquiterpenoids (47.9% for S and 54.7% for G) and hydrocarbons (25.9% for S and 31.7% for G). Germacrene D (13.3%), (E)-β-farnesene (8.3%), nonacosane (7.3%), heptacosane (6.5%) and phytol (6%) were recognized as the main constituents for S, while caryophyllene oxide (17.7%), nonacosane (14.5%), germacrene D (11.5%), caryophyllene (11.2%) and heptacosane (10.3%) were the main compounds for G.
Volatile components from aerial parts of centaurea spinosociliata seenus ssp. Cristata (Bartl.) Dostál and centaurea spinosociliata seenus ssp. spino…
2010
The paper reports on the volatile components oil from aerial parts of two Asteraceae growing wild in Croatia: Centaurea spinosociliata ssp. cristata (syn. Centaurea cristata Bartl. subsp. rabenhorstiana (Sch.Bip.) Nyman) (CSC) and C. spinosociliata ssp. spinosociliata (CSS). The volatile components were obtained by hydrodistillation from selected plants and were determined by the GC-MS system on two fused-silica capillary columns of different polarity. The oil content was 0.08 % (CSC) and 0.07 % (CSS) on a dry weight basis. Altogether 73 compounds were identified accounting for 90.8 % (CSC) and 92.8 % (CSS) of the total oil, that were characterized mainly by hydrocarbons (37.9 %; 30.4 %), s…
Volatile constituents of the aerial parts of white salsify (Tragopogon porrifolius L., Asteraceae).
2010
Tragopogon porrifolius L. grows as a vegetable in southern Italy and all parts of it are edible. In the present study the volatile components of the aerial part are described. Gas chromatography and gas chromatography-mass spectrometry analysis showed the presence of 38 components in all. On the whole, the volatile fraction was constituted mainly by carbonylic compounds (24.6%), phenols (21.5%) and fatty acids and esters (19.7%). The most abundant compounds were 4-vinyl guaiacol (19.0%), hexadecanoic acid (17.9%), hexahydrofarnesylacetone (15.8%) and hentriacontane (10.7%).

Early Antecedents of School Burnout in Upper Secondary Education : A Five-year Longitudinal Study
2020
AbstractSchool burnout symptoms are prevalent among upper secondary education students, but thus far, very little is known about the background of these symptoms. The present study examined the extent to which school burnout symptoms (i.e., exhaustion and cynicism) among upper secondary education students have their roots in primary and lower secondary school and whether early antecedents of school burnout symptoms could be identified. The sample consisted of 1544 Finnish students followed up four times (Time1–Time 4) from the end of primary school (T1; mean age 12.74 and range 11.71–14.20) to the first year of upper secondary education (T4; mean age 16.66 and range 15.55–18.39). The result…
