Attosecond pulses are used to study electron dynamics in atoms and molecules. In this thesis, schemes to control the generation of attosecond pulses and pulse-shaping techniques to compress the pulses are presented. Generation of attosecond pulses requires high intensity, which is reached by focusing a pulsed femtosecond laser. The emitted pulses come isolated or in an attosecond pulse train (APT
Background: High activity of cysteine proteases such as legumain and the cathepsins have been shown to facilitate growth and invasion of a variety of tumor types. In breast cancer, several recent studies have indicated that loss of the cysteine protease inhibitor cystatin E/M leads to increased growth and metastasis. Although cystatin E/M is normally expressed in the skin, its role in cysteine pro
A method to study total deposition of aerosol attached radon progeny in children and adults have been validated and used in home environments. Two persons, one child and one adult are tested simultaneously, thus inhaling from the same aerosol and allowing for a direct comparison. The aim of the study was to increase the knowledge of the lung deposition and thereby the knowledge of the radiation do
In order to reduce parasite-induced mortality, hosts may be involved in mutualistic interactions in which the partner contributes to resistance against the parasite. The pea aphid, Acyrthosiphon pisum Harris (Hemiptera: Aphididae), harbours secondary bacterial endosymbionts, some of which have been reported to confer resistance against aphid parasitoids. Although this resistance often results in d
Using the optical double resonance and level crossing methods, properties of several excited S , P , and D states in 39 K were studied. The S and D states were populated using stepwise excitation with the first P state as an intermediate level. An rf lamp and a CW dye laser were used in the first and second excitation steps, respectively. The studied P states were populated in the cascade decay of
In the 19th century, an extensive liberal and Christian international peace movement developed. In 1891, an umbrella organization, the International Peace Bureau (IPB), based in Bern, was formed to coordinate the international peace work that had previously been divided into a number of different national and international federations. This would prove successful. The establishment of a Nobel Priz
This Master Thesis project is performed at Tetra Pak in Modena, Italy. The overall objective of the overall Locking Pin project as this thesis project is a part of, is to understand the root cause of a failing locking pin. The locking pin is located in a filling machine and failures due to fatigue. The function of the locking pin is to bind up the filling pipe to a pressure flange. The locking pin

Den här artikeln är över 5 år gammal, och informationen kan därför vara inaktuell. Professor Reza Banakars bok "Normativity in Legal Sociology. Methodological Reflections on Law and Regulation in Late Modernity" har nyligen släppts. Den studerar normativitetens roll i rättssociologisk forskning och tittar också på de utmaningar som de sociokulturella konsekvenserna av globaliseringen utgör för den
