Effect of the remaining lanthanide catalysts on the hydrolytic and enzymatic degradation of poly-(ε-caprolactone)
2003
Poly-(e-caprolactone) is a biodegradable polymer, which can be used for both medical and environmental applications. Due to its multiple applications the synthesis of such a polymer has been attracting an increasing attention in the past few decades. In our work, the polymers were synthesised by bulk polymerisation, using different lanthanide halides as initiators. The lanthanide derivatives are known as very active catalysts in the ring-opening polymerisation of cyclic esters. Moreover, they are not toxic in comparison of catalysts, which are usually used for this synthesis. In this paper, the influence of the lanthanides on both the hydrolytic and enzymatic degradation of the PCL obtained…
E-læring, dialog og kommunikasjon - Et følgeforskningsprosjekt i tilknytning til Regionalt samarbeidsprosjekt om lederopplæring
2007
Denne rapporten presenterer resultater fra følgeforskning i tilknytning til Regionalt samarbeidsprosjekt om lederopplæring. Prosjektet har siktet mot å realisere avtalen om et inkluderende arbeidsliv (IA) ved å skolere mellomlederes kommunikative egenskaper. Lederopplæringen har hatt deltakere fra kommunene Birkenes, Vennesla, Mandal, Søgne, Lillesand, Songdalen og Kristiansand, samt Vest-Agder fylkeskommune. Programmet som bestått av tre samlinger med støtte fra e- læringsverktøy og en kursbok. Undersøkelsen viser at de aller fleste deltakerne er svært fornøyde med programmet. De er særlig fornøyde med samlingene. E-læringsverktøyet og kursboka er beskrevet som et viktig og positivt supple…
(Table 1) Geochemistry of ODP Site 160-963 sediments
2010
The Mediterranean Sea acts as a miniature ocean with the development of its own conveyor belt. It constitutes an ideal location to study and forecast how the marine environment responds to rapid climatic change. Here we present a palaeoenvironmental study carried out on the sediments of ODP Site 963, recovered in the Sicily Channel, the sill which divides the western from the eastern Mediterranean basin. We focused on the transition between the penultimate glacial (MIS 6) and the last interglacial (MIS 5), between approximately 130 and 115 kyr BP. A novel approach is proposed, taking into account centennial-scale geochemical data on major elements, selected trace elements, and yttrium and R…
Liikunnan yhteisopetus yläkoulussa - oppilaan toive vai kauhistus : tapaustutkimus yhden yhteisopetukseen siirtyneen luokan oppilaiden kokemuksista
2017
TIIVISTELMÄ Lassila, S. 2017. Liikunnan yhteisopetus yläkoulussa – oppilaan toive vai kauhistus? Tapaustutkimus yhden yhteisopetukseen siirtyneen luokan oppilaiden kokemuksista. Liikuntatieteellinen tiedekunta. Jyväskylän yliopisto, Liikuntapedagogiikan pro gradu – tutkielma, 58. Suomen kouluhistorian alussa koulumaailma oli jakautunut sukupuolten mukaan poikakouluihin sekä tyttökouluihin. Liikuntaa alettiin opettaa pojille pakollisena oppiaineena vuoden 1840 alussa, ja tytöt pääsivät oppimaan liikuntaa vuodesta 1899 alkaen. Vasta vuonna 1975 kumottiin laki, jonka mukaan nainen ei ollut kelpoinen eräisiin valtion virkoihin tai toimiin. Tämän kumoamisen jälkeen monissa alakouluissa alettiin …
The Anti-Samaritan Attitude as Reflected in Rabbinic Midrashim
2021
Samaritans, as a group within the ranges of ancient ‘Judaisms’, are often mentioned in Talmud and Midrash. As comparable social–religious entities, they are regarded ambivalently by the rabbis. First, they were viewed as Jews, but from the end of the Tannaitic times, and especially after the Bar Kokhba revolt, they were perceived as non-Jews, not reliable about different fields of Halakhic concern. Rabbinic writings reflect on this change in attitude and describe a long ongoing conflict and a growing anti-Samaritan attitude. This article analyzes several dialogues between rabbis and Samaritans transmitted in the Midrash on the book of Genesis, Bereshit Rabbah. In four larger sections, the f…
The Ba2LnFeNb4O15 “tetragonal tungsten bronze”: Towards RT composite multiferroics
2009
Several Niobium oxides of formula Ba2LnFeNb4O15 (Ln = La, Pr, Nd, Sm, Eu, Gd) with the Tetragonal Tungsten Bronze (TTB) structure have been synthesised by conventional solid-state methods. The Neodymium, Samarium and Europium compounds are ferroelectric with Curie temperature ranging from 320 to 440K. The Praseodymium and Gadolinium compounds behave as relaxors below 170 and 300 K respectively. The Praseodymium, Neodymium, Samarium, Europium and Gadolinium compounds exhibit magnetic hysteresis loops at room temperature originating from traces of a barium ferrite secondary phase. The presence of both ferroelectric and magnetic hysteresis loops at room temperature allows considering these mat…
Preparation of Sm-loaded brookite TiO2 photocatalysts
2011
Abstract Pure and Sm-loaded brookite nanoparticles and thin films were prepared using TiCl4 as precursor of TiO2. The samples were characterized by X-ray diffraction (XRD), specific surface area (SSA) determination, diffuse reflectance spectroscopy (DRS) and photoluminescence (PL) measurements. The photocatalytic activity of the powders was investigated by employing the photodegradation of 4-nitrophenol in a liquid–solid system whilst the photoreactivity of the films was tested by evaluating the rate of degradation of 2-propanol in a gas–solid system. Loading with Sm resulted in a significant improvement of the photoreactivity of brookite and the beneficial effect was attributed to an incre…
Piedziņas vēršana uz parādnieka naudas līdzekļiem
2016
Latvijas Universitātes Juridiskās fakultātes tiesību zinību maģistra studiju programmas students Toms Rajunčus ir autors maģistra darbam ar tēmu “Piedziņas vēršana uz parādnieka naudas līdzekļiem”. Parādu piedziņa, līdzīgi kā lielākā daļa tautsaimniecības nozaru, ir pakļauta konkrētam tiesiskajam regulējumam, kas nosaka nozares darbības specifiku. Parādu piedziņas tiesiskā regulējuma mērķis, galvenokārt, ir noteikt skaidru kārtību, kādā ir vēršama piedziņa pret parādnieku mantu, lai aizsargātu parādniekus no piedzinēju un izpildinstitūciju patvaļas. Ar grozījumiem Civilprocesa likumā, kas stājušies spēkā 2014.gada sākumā ir būtiski mainījusies kārtība, kādā piemērojams galvenais piespiedu i…
DARBA SAMAKSAS ATŠĶIRĪBAS STARP DZIMUMIEM LATVIJĀ NO 2007. LĪDZ 2013. GADAM
2016
Ekonomikas krīzes laikā pieauga sieviešu nodarbinātības daļa kopējā nodarbinātībā, tomēr aktuāla problēma arvien ir darba samaksas atšķirības starp dzimumiem. Bakalaura darba mērķis ir novērtēt šīs atšķirības Latvijas tautsaimniecības nozarēs no 2007. līdz 2013. gadam, aprēķinot nekoriģētās darba samaksas atšķirības (balstoties uz bruto darba samaksu mēnesī). Kā arī veikt hipotēžu pārbaudi par darba samaksas atšķirībām sektoros ar lielu sieviešu vai vīriešu dominanci, konkrēti, veselības, izglītības, būvniecības un elektroenerģijas, gāzes apgādes, siltumapgādes un gaisa kondicionēšanas sektoros. Rezultāti liecina, ka pastāv abu metožu rezultātu sakritība, tomēr tās būtu lietojamas papildino…
Sm-Nd dating of Fig Tree clay minerals of the Barberton greenstone belt, South Africa.
1994
Sm-Nd isotopic data from carbonate-derived clay minerals of the 3.22-3.25 Ga Fig Tree Group, Barberton greenstone belt, South Africa, form a linear array corresponding to an age of 3102 +/- 64 Ma, making these minerals the oldest dated clays on Earth. The obtained age is 120-160 m.y. younger than the depositional age determined by zircon geochronology. Nd model ages for the clays range from approximately 3.39 to 3.44 Ga and almost cover the age variation of the Barberton greenstone belt rocks, consistent with independent evidence that the clay minerals are derived from material of the belt. The combined isotopic and mineralogical data provide evidence for a cryptic thermal overprint in the …
