Enantioselektiv HPLC-analys med kirala stationärfaser bestående av makrocykliska glykopeptider och polysackarider

The purpose of this study was to evaluate enantioselective analytical methods by separation of the enantiomers of four drugs (citalopram, zopiclone, tramadol and methylphenidate) and their metabolites. The analyses were performed with HPLC-UV with columns whose stationary phases were based on macrocyclic glycopeptides (Chirobiotic V, V2 and T) and polysaccharides (Lux Cellulose-1, Cellulose-2 and Amylose-2).The Chirobiotic V column showed high selectivity for citalopram and its metabolites. High resolution was obtained using a mobile phase consisting of methanol, acetic acid and ammonia. High selectivity for the enantiomers of zopiclone and its metabolites were obtained on the Cellulose-2 column using a mobile phase consisting of acetonitrile and ammonium acetate buffer.The enantiomers of tramadol were separated with the Amylose-2 column. However, changes in the pressure arose, probably caused by the additive NH4HCO3.

Ordets blomma kommer inte att dö : att förändra världar genom globala nätverk

Social movements have long been valuable components of the struggle for a world with true justice. Along with the changing and modernization of society these movements also change, both in their actions as well as in the goals they want to accomplish. Technology is taking a greater part in many aspects of social life, creating new dimensions but also new social divides. This thesis examines how new social movements make themselves visible and affect the world around them through different kinds of networks. For the purpose of this study, we have chosen to study two social movements; the Zapatistas in Mexico, who have become known worldwide for carrying out the first informational revolution, and MoveOn.org, an American grassroots organization that struggles for increased democracy in the US.

Informationssökning i tre olika hypertextstrukturer - ett experiment

The aim of this study was to find out if hypertext structure has any relevance for the efficiency of information retrieval. An experiment, in which three variants of hypertext structure were compared, was carried out in the autumn of 1998. Three websites with different structures were constructed for this purpose: a sequential version, a hierarchical version and a webcluster version. 44 subjects, all students at the University of Lund, were randomly divided into three groups. Subjects were requiered to answer a number of questions using one of the three versions.

Hur upplever gymnasieelever sin informationssökning? En studie på en skola utan tillgång till skolbibliotek

Yngre elevers motivation till skolbloggsskrivande

Detta examensarbete visar på vilka faktorer somyngre elever finner motiverande när det kommer till att skriva en skolblogg. Undermin senaste verksamhetsförlagda utbildning genomförde jag projektet skolblogg.Alla elever i åk 5 fick starta varsin skolblogg. Under mina fem veckors praktikså observerade jag att eleverna tyckte detta var ett roligt sätt att arbeta på.Jag har intervjuat 12 av eleverna i denna klass för att ta reda påmotivationsfaktorerna till skolbloggsskrivandet. De faktorer som jag kom framtill är: att andra kan läsa, att få göra något nytt och annorlunda, att få mertid med datorn, att få skriva, att kunna läsa klasskompisarnas skolbloggar, attfixa med designen mm. Kunskap om elevers motivation får oss lärare att förståeleverna bättre vilket i sin tur leder till att vi kan anpassa undervisningen.Förhoppningsvis kan detta arbete leda till att lärare kan få en insyn iskolbloggen som undervisningsmöjlighet och bidra till en förståelse för attInternet ger oss den möjligheten..
