Long-term changes in pigmentation of arctic Daphnia provide potential for reconstructing aquatic UV exposure

2016

Abstract Despite the biologically damaging impacts of solar ultraviolet radiation (UV) in nature, little is known about its natural variability, forcing mechanisms, and long-term effects on ecosystems and organisms. Arctic zooplankton, for example the aquatic keystone genus Daphnia (Crustacea, Cladocera) responds to biologically damaging UV by utilizing photoprotective strategies, including pigmentation. We examined the preservation and content of UV-screening pigments in fossil Daphnia remains (ephippia) in two arctic lake sediment cores from Cornwallis Island (Lake R1), Canada, and Spitsbergen (Lake Fugledammen), Svalbard. The aims were to document changes in the degree of UV-protective p…

Chemical Composition of the Essential Oil of Bupleurum Fontanesii (Apiaceae) Growing Wild in Sicily and its Activity on Microorganisms Affecting Hist…

2016

Hydrodistillation of the flowers (BpFl) of and fruits (BpFr) of Bupleurum fontanesii Guss. ex Caruel gave two oils that were analyzed by GC and GC-MS. The main components were α-elemol (16.7%), caryophyllene oxide (16.4%) and heptacosane (15.9%) in BpFl, and spathulenol (16.8%), caryophylladienol I (13.2%) and α-elemol (12.8%) in BpFr. A good antimicrobial activity against several microorganisms, including Bacillus subtilis, Staphylococcus aureus, Fusarium oxysporum and Aspergillus niger, all infesting historical art craft, was also determined.

Laulaminen puhehäiriöiden kuntoutuksessa

2014

Kandidaatintutkielmani on tarkka kuvaus äänentuottoprosessista ja siinä ilmenevistä vaikeuksista. Tutkielmani alkuosioissa perehdyn laulun ja puheen äänentuoton neurologiseen ja fysiologiseen prosessiin ja äänentuottoelimistön toimintaan. Lisäksi selvitän laulun ja puheen yhtäläisyydet ja eroavaisuudet, jotka toimivat osittain perusteluina puhehäiriöiden musiikilliselle ja laululliselle kuntoutukselle. Selvitän eri puhehäiriöiden aiheuttajia ja kuvaan niiden oirekuvia, sillä erilaisten puhehäiriöiden kuntouttamisessa tulee ottaa huomioon millaisesta puhehäiriöstä on kyse ja millaisia terapiamalleja niihin tulee soveltaa. Määrittelen ”lauluterapia”-termin musiikkiterapian ja puheterapian väl…

Dialogisuuden toteutuminen ja asiakkaan äänen kuulluksi tuleminen masennuksen pariterapiassa

2012

Tämän pro gradu -tutkielman tavoitteena oli tarkastella dialogisuuden toteutumista ja masentuneen asiakkaan äänen kuulluksi tulemista pariterapiassa. Lisäksi vertailimme, erosivatko terapeuttien vastaustavat niiden istuntojen välillä, jotka masentunut asiakas oli arvioinut kuulluksi tulemisen suhteen hyviksi ja huonoiksi. Tutkielma on osa Jyväskylän yliopiston psykologian laitoksen Dialogiset ja narratiiviset prosessit masennuksen pariterapiassa -projektia (DINADEP), ja aineistonamme oli projektin yhden pariskunnan terapiaprosessi, joka oli tulokseton. Analysoimme terapeuttien vastaamista masentuneelle asiakkaalle laadullisella monitoimijaisen dialogin tutkimusmenetelmällä (Dialogical Metho…

The chemical composition of the aerial parts essential oil of Ferulago nodosa (L.) Boiss. (Apiaceae) growing wild in Crete (Greece)

2023

Ferulago nodosa (L.) Boiss. (Apiaceae) is a species occurring in the Balkan-Tyrrhenian area being present in Crete, Greece, Albania, and probably in Macedonia. Although the western disjointed population of Sicily has been classified as an endemic sub-species, F. nodosa subsp. geniculata (Guss.) Troia & Raimondo, its official acceptance is quite controversial. In order to verify the existence of two different sub-species, we investigated the chemical composition of the essential oil of F. nodosa, collected in Crete (Greece), not previously reported, and we compared it with the previously oil compositions reported in literature. Main constituents of the Cretan accessions of F. nodosa were…

Characterization and antimicrobial activity of the volatile components of the flowers of Magydaris tomentosa (Desf.) DC. collected in Sicily and Alge…

2014

The essential oils of the flowers of Magydaris tomentosa (Desf.) DC. (Apiaceae) collected in Sicily (MSi) and Algeria (MAl), respectively, were obtained by hydrodistillation, and their compositions were analysed. The analyses allowed the identification and quantification of 23 components in MSi and 60 compounds in MAl, respectively, showing a very different profile in the composition of the two populations. The main components of MSi were cembrene (28.2%), α-springene (17.5%) and β-springene (14.8%), also present in MAl but in lesser amount (0.4%, 1.8% and 0.9%, respectively), whereas the principal constituents of MAl were (E)-nerolidol (35.4%), α-costol (13.3%) and β-costol (6.8%). Both MS…
