Despite the recent theoretical and empirical advancements in the geography of innovation literature regarding the role that global sources of knowledge may have for regional growth and development, research in this field remains focused on successful regions and clusters in developed countries. Hitherto there has been limited research on the role of regions located in developing countries and the

The sound transmission in double walls at low frequencies is studied using a detailed geometric model, based on FEM. The model simulates the experiments carried out to determine the sound reduction index of the wall. The wall properties effect on the sound transmission loss is investigated and also how the sound reduction is affected by the dimensions of the connecting rooms.

Popular Abstract in Swedish Pi-konjugerade polymerer är ett viktigt slag av material. För det första så har det många eftertraktade fysikaliska egenskaper som förmågan att leda elektrisk ström, omvandla elektriska laddningar till ljus, eller omvänt, omvandla ljus till elektricitet. Dessa material tillämpas redan i stor utsträckning i dag som i exempelvis plattskärms-TV (OLED) och i mobiltelefoner.Π-conjugated polymers are an important class of materials which can be used in e.g. photoelectric (solar cells) or electroluminescent (displays) devices. These materials are implemented in a number of applications these days since a lot is already known about them. There is, however, still a lot to learn in order to increase the efficiency and reduce the power consumption of devices. There are man

In Munich a new high-flux reactor FRM-II is under construction with properties similar to the HFR reactor at the ILL (Grenoble). For the Munich reactor a fission fragment accelerator is under design, where the ion source is operated at maximum neutron flux. The accelerator will deliver intense mass-separated beams-of very neutron-rich fission fragments with energies at and beyond the Coulomb barri

New Information Systems Development Methodologies (ISDMs) are suggested in the belief that their deployment would be beneficial to consultants in their work. A large number of ISDMs already exist but their value has been questioned and at the same time new methodologies continue to be introduced in an attempt to support and improve the practice of information systems development work. What is not

Early cybernetics emphasized control and communication in the animal and the machine. Subsequent understandings of linguistic phenomena in the animal have shown them not to be reducible to purely mechanistic models. The linguistic complementarity, with its possibilities for transcendence, provides such an understanding, indicating relativistic approaches within modern systems theory. Comparisons a

Traditional high level synthesis is able to yield high computational resource utilisation and short critical paths. The shortcomings of the generated designs usually lies in the memory architecture. To achieve good performance on a FPGA, the data must reside in the fast on-chip memories, but these are commonly too small for the data being processed. Traditional high level synthesis cannot cope wit

The way in which the cortical cytoskeleton associates to the plasma membrane (PM) must be elucidated to understand the structural dynamics of many processes in the plant cell. In the present study, isolated cauliflower (Brassica oleracea L.) PM vesicles were used to characterize membrane/cytoskeleton interactions. Both actin and tubulin were shown to copurify with PM vesicles and this copurificati

Popular Abstract in Swedish I världen beräknas det finnas cirka 38 miljoner blinda människor enligt Värdshälsoorganisationen (WHO). Av dessa är 1,5 miljon barn under 16 år. Blindhet definieras av WHO som bästa korrigerade synskärpa under 0,05 (man klarar således inte att läsa översta raden på en vanlig synprövningstavla på halva normalavståndet), detta med bästa glasögonkorrektion och med båda ögoKnowledge of the epidemiology of visual impairment in children forms one of the cornerstones in paediatric ophthalmology. To gain an overview of the situation in Sweden an epidemiological study was performed. Totally 2373 visually impaired children were found, giving an age-specific prevalence of 10,9/10 000. Childhood blindness (i.e. vision <0,05) was seen in 25%. Male/female ratio was 1,20. Addi
