Enantioselektiv HPLC-analys med kirala stationÀrfaser bestÄende 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.

The petrol station ? a hot spot along the road

The increased travelling of today makes nodes along travelling routes more and more important. This is very much the case of petrol stations. They constitute important nodes in the road network, filling up thirsty fuel tanks and hungry stomachs, guiding road users and providing vehicle-services. In this thesis the role of the petrol station for road users was investigated in order to find out if the petrol station was a potential hot spot. We performed an ethnographic field study at a petrol station and found that a great number of visitor activities took place at the petrol station.

Webbradion : ett nytt medium

The purpose of this essay is to study the role of web radio in Sweden. To fulfill the purpose we have done a case study of two Swedish radio stations: Sveriges Radio AB, which is a public service station, and a commercial station called Mix Megapol. By interviewing two persons from each station and analyzing the contents of their web sites, we have tried to see how the relationship between radio, Internet and web radio looks like. Thus, our method is qualitative. We have come to many conclusion of which some are: The new medium web radio borrows qualities from the traditional radio.

Konsten under jorden : En analys av Ulrik Samuelsons konst i KungstrÀdgÄrdens tunnelbanestation

This study examines the work of art in the underground station KungstrÀdgÄrden in Stockholm and discusses the observers interpretation of the art in the station. When the artist Ulrik Samuelson got his commission to shape the station he was influenced by Marcel Duchamp and the concept art. Two themes were integrated in the work of art, the actual culture life and the palace called Makalös, which was situated just above the currant station, three hundred years ago. The station was built in two stages.The first part was opened in 1977 and the second part in 1987. PanofskyŽs iconographic working method has been used in this essay.

Base stations for communication in obstructed environments

The purpose of this project was to produce signal relay stations that could receive information via 2.4 GHz radio and relay the information to a designated target station. If a relay station was located outside of signal range for the target station it was supposed to utilize other relay stations to transfer the information to the target station, so called multi-hop.The would-be application of the relay stations was orienteering. When an orienteer punches a checkpoint the signal stations would relay information of who punched the control, when it was punched and the checkpoint that was punched to the speaker tower in the goal area.The work resulted in prototypes which fulfilled the statement of purpose and was tested at an orienteering competition with satisfactory results. The performance of the prototypes was tested and found adequate for the would-be application..

The German equine housing system, HIT Active Stable?, are adjusted for keeping horses in groups, and are well establishes in Germany. Now the system attracts attention here in Sweden. The purpose of this study was to investigate if the horses have any be-haviours need of free access to roughages like straw or hay, after they have been visit the concentrate feeding station. A study was carried out at family Krohn?s active stables in Bönningstedt, Germany.

Ändrad anvĂ€ndning av stationshus : fallet Ormaryds station ? ett stationshus med betydande kulturvĂ€rden

Acquiring a former station building can mean that the property owners must familiarize themselves with a lot of planning and building regulations. After the new Planning and Building Act code into force in 2011, the responsibility lie on the developer to ensure laws and regulations. Based on the regulatory framework that is available occurs sometimes balance issues, between care requirements and building codes. The station building in Ormaryd was acquired in 2009 by two individuals who intended to accommodate office and retail space in the building. In doing so a new local plan of the area was established, including regulations on how the building could be used. By including road safety and noise, the risk was not considered appropriate to use the station building for housing.

Projektering för Äterupptagandeav elproduktion vid smÄskaligtvattenkraftverk

Due to historically low prices for electricity in Sweden, many small-scale hydropowerplants were closed down. A small-scale power plant has more or less the samemaintenance costs as larger plants, but doesn?t generate as much income. Today?sincreasing price for electricity in combination with a desire for renewable energysources makes small-scale hydropower interesting again.

VÀrdefull eller vÀrdelös? - Kulturhistorisk vÀrdering och fÀrjestationen i Helsingborg

This essay in historical archaeology deals with cultural-historical values of buildings and inthis case the old train- and ferrystation in Helsingborg. The building has from the day of itsopening in 1898 been exposed to threats of demolition since its original purpose was as atemporary building with intension of being replaced within a couple of years. After havingseen two World Wars, eventhough Sweden never participated, and the ferrytraffic with its upsand downs the station was an important part of Helsingborg. All the ferrytraffic over the straitto Denmark was handeled by the old train- and ferrystation untill 1955, when a competativeferrycompany was built close to the old station. After a hundred years of service the oldstation was closed down when a new station was built i Helsingborg in 1991 with theintension of gathering all travelers in one building.

Analys av fri stationsuppstÀllning med totalstation med avseende pÄ mÀtta lÀngder och riktningar

Stationsetablering innebÀr bestÀmning av ett mÀtinstruments fysiska lÀge och orienterad riktning. I dagens bygg- och anlÀggningsbransch anvÀnds nÀstan uteslutande fri station för att etablera en stationspunkt för mÀtningar. PÄ en byggplats Àr tillgÄngen till referensobjekt ofta begrÀnsad. Instrumentets placering blir dÀrför en kompromiss mellan tillgÄng till referensobjekt och tillgÄng till den plats dÀr inmÀtning respektive utsÀttning skall ske. Denna kompromiss ger upphov till skiftande geometriska konfigurationer hos referensobjekten, vilka pÄverkar mÀtresultatet.Studiens syfte Àr att undersöka om simuleringar av fria stationsuppstÀllningar i Svensk Byggnadsgeodesis (SBG:s) programvara Geo verifieras av fÀltmÀtningar och efterföljande berÀkningar av osÀkerhetsparametrar orsakade av konfiguration och mÀtta lÀngder och riktningar.
