The ability to sense the surrounding environment and respond to external fluctuations is a fundamental property of cells, the basic unit of life. Although cells can be very different in their composition and structure, they all have specialized molecular mechanisms that allow them to adapt to their environment, by coordinating gene expression and protein production. In this thesis, we focus on a s

International research has emphasised the importance of anti-Catholicism for the processes of identity formation across Europe, both for established Protestant Churches and for national liberal movements. The connection between anti-Catholicism and other ‘anti’ movements such as antisemitism, anti-feminism, and anti-socialism has also been pointed out. Much like these movements, anti-Catholicism w

There is an increasing interest in open source, which also goes for enterprise resource planning (ERPs) systems, especially when it comes for small and medium sized enterprises (SMEs). In this article, the focus is on the combination of open source and ERPs, and specifically on what role development of open source ERPs plays in diffusion of ERPs among SMEs. In an effort to be able to explain the i

The erection process of in-situ cast concrete frameworks in multi-storey housing involves a wide range of non-value adding activities, resulting in poor process efficiency. This paper describes the process and presents a model for discrete-event simulation of activities and resource use involved in the construction of in-situ cast concrete frameworks. The model simulates the work flow which is sub

We present a low-delay vector predictive transform coder with quantization noise modeling. The coder uses overlapped transform coding and a Kalman filter with a backward estimated LPC model of the speech signal combined with an additive noise model of the quantization noise. The noise model is driven by the vector quantizer. Each quantizer cell has its own error correlation matrix, which is kept i

In this paper we describe a simple way of analytically computing entire ìterm structures of default probabilities using information embedded in the corporate bond market data. This market-based approach of estimating the creditworthiness of firms gives probabilities of default at various maturities, and has the advantage over traditional credit ratings in that it is dynamic and forward looking.

Det finns flera anekdotiska bevis för att lärare och studenter anser att det är stor skillnad på naturvetar- och ingenjörsstudenter. För att ge en utgångspunkt för diskussioner på detta tema presenterar vi här en undersökning av två studentgrupper kemitekniker och naturvetare som läst liknande organkemikurs med samma lärare. De första preliminära resultaten visar att skillnaden mellan grupperna fr

Popular Abstract in Swedish Popularized summary in Swedish (Sammanfattning på svenska) Blödarsjuka - hemofili - är en ärftlig sjukdom som endast uppträder hos män och som överföres av kvinnliga bärare vilka ej är blödare. Sjukdomen tar sig uttryck i en abnorm blödningsbenägenhet med framför allt ledblödningar och då redan från tidig ålder. Det finns två typer av blödarsjuka, hemofili A respektiveIn patients with severe hemophilia it is today possible to prevent the development of arthropathy by giving effective continuous prophylaxis from an early age, thus preventing the VIII:C or IX:C concentration from falling below 1% of normal. All the signs show that if a high-dose prophylactic regimen - that is, 3,000-5,000 U/kg body weight annually - is started as early as 1-2 years of age, the pa

The Swedish model of industrial relations is analyzed with respect to some closely related dimensions: collective agreements - legislation, cooperation - confrontation, self-regulation - state regulation and centralisation - decentralisation. Both the historical development and the present state of the model are discussed. In an analytical table the dimension self-regulation - state regulation is
