I Sverige är höghastighetsjärnvägar ett debatterat ämne. Undersökningsarbeten har startat för det första steget i ett höghastighetsnät – Ostlänken mellan Järna och Linköping – som planeras vara trafikerad år 2028. Höghastighetsjärnvägen är avsedd att tillåta hastigheter på 320 km/h. Vid så höga hastigheter blir dimensioneringskraven för brobanans vibrationer strängare. Tidigare studier har visat aIn Sweden, high-speed railways is a subject for public debate. The first stage of a high-speed train network, Ostlänken between Stockholm and Linköping, is under investigation, and is planned to be trafficked in 2028. The high-speed railway is intended to hold traffic with speeds up to 320 km/h. At such speeds, the design requirements of the accelerations of the bridge superstructure become more s

This paper aims to demonstrate the extent to which the resource abundance can explain the unsustainable economic development process of Kazakhstan. It aims to answer the overarc

The main aim of the present study was to study memory interference using a more ecological approach, where competing events can be separated by the environmental context. In order to increase the ecological validity of the study, context was manipulated through the presentation of video clips instead of commonly used static pictures. The second aim of the study was to assess if the contextual cues

I svenska städer besår cirka 50 % av städernas grönytor av parker, kyrkogårdar, parkleder, men även av trädgårdar. Den här studien visar att äldre trädgårdar är större och grönare. Varför är då privata trädgårdar i urbana miljöer av intresse? Privatägda trädgårdar bidrar i stor utsträckning till den totala andelen grönyta i urbana miljöer. Grönytor bidrar till infiltration av dagvatten, vilket min

Monoclonal antibodies represent an attractive approach for treatment of cancer. Phage display is a very powerful technique to display large antibody libraries, which can be used to isolate therapeutic antibodies. Panning of phage display libraries against cells generates complex antibody pools, and direct screening of such pools typically identifies high-frequent antibodies against highly expresse

This study relates to the transcription of foreign personal names into kanji in Japanese. The study is based upon a paper where Tokimoto & d’Arcais (2000) confirmed three working principles when natives transcribe place names written in hiragana: that jukugo reading will be preferred over juubako reading, that as few kanji segmentations as possible will be used, and that the names will be segm
