Popular Abstract in Swedish Betydelsen av tryckinducerad syrgastransport hos övervattensväxter Min avhandling handlar om vikten av att syrgas transporteras till rötter och rhizom hos övervattensväxter som bladvass, kaveldun och säv. Syrgas behövs för cellandningen i alla växtdelar, och i synnerhet i rötterna då de växer fort och har hög ämnesomsättning. Övervattensväxter har rötterna i vattendränThis thesis examines factors regulating growth and distribution of emergent plants with focus on effects of oxygen supply to the roots. Greenhouse experiments revealed that P. australis acclimatizes to specific water depths with phenotypic plasticity. These phenotypic responses act to increase growth at specific water depths but may result in decreased tolerance to changed water depth. Oxygen nee

Popular Abstract in Swedish Sjukdomar associerade till fästingar har ökat över hela världen och näst efter myggor är fästingen den vektor som orsakar mest sjukdom hos människan. I Sverige sprider fästingen sjukdomar såsom borreliainfektion, fästingfeber (erlichia) och fästingburen hjärninflammation (TBE) vilka orsakas av såväl bakterier som virus. Borreliainfektion är den vanligaste fästingburna sThe incidence and variety of diseases associated with ticks have increased world-wide and ticks are currently considered to be second only to mosquitoes as vectors of human infectious diseases in the world. In the northern hemisphere, Ixodes ricinus, the most common tick, transmits diseases caused by several infectious pathogens, including different types of bacteria, virus and protozoa. In Sweden

The article discusses the urbanisation of Insula V 1 in the late second century B.C. Wall anlysis clearly reveals that the plots were covered with architecture in a chronological sequence advancing from south to north. The impact of natural water is discussed in connection with the slope of the hill. It is presented as constraint that had to be taken into account in construction all over the insul

In this paper, we present a new multiple access scheme using OFDM modulation which we call braided code division multiple access (BCDMA). The principle behind this novel multiple access technique is to combine in one single scheme a very efficient error correction code, interleaving for channel diversity exploitation and, simultaneously, a multiple access method for a large number of users. BCDMA

The aim of the user related assessment was to study perceived advantages, disadvantages, usefulness, trust, acceptance, willingness to have and pay for the driver assistance systems: Safe Cruise and Speed Support developed by VCC within the framework of SECONDS subproject. Due to restrictions in driving in real traffic, assessment activities were limited to driving on a test track by naïve test dr

The performance of a turbo code is dependent on two properties of the code: its distance spectrum and its suitability to be iteratively decoded. Both these properties are dependent on the specific interleaver used in the turbo-coding scheme. This paper describes a strategy for interleaver design that includes a criterion for the performance of iterative decoding. This criterion is based upon corre
