Water vapor condensation and two-phase flow appear in plate heat exchangers being used as condensers. Analysis of water phase change and flow dynamics is an important but complicated task due to large change in water physical/transport properties across the water liquid-vapor interface boundary. In particular, a singular-link behaviour in Navier-Stokes (N-S) equations is present due to the large s
Popular AbstractAvhandlingen presenterar, från ett fenomenologiskt perspektiv, interaktionen mellan naturvetenskapens kunskap och annan kunskap, här kallad "vardagskunskap". Utgångspunkten i presentationen är människans existens. Två aspekter av denna lyfts fram som centrala - att människan är kroppsligt utsatt för, berörd av, något hon inte har full kontroll över, samt att hon alltid agerar utifrThe dissertation presents a phenomenological view on the interaction between science knowledge and prescientific knowledge. Drawing on Husserl, Merleau-Ponty and Lévinas the human bodily grounded existence is described, the central feature of this existence being its responsivity to the Other. This responsivity is presented as the starting point for the production of science knowledge, thus making
This work is theoretical analyses of heat transfer across film a flowing over the surface of a rotating disk. This field has wide industrial applications in Turbomachinery, chemical, and food industries. An analytical study is developed to investigate the heat transfer characteristics in the liquid film due to jet impinging at the center of the disk. A theoretical model is based on heat balance an
Antibody-based microarrays have emerged as an established proteomic technology allowing multiplexed and sensitive profiling of complex proteomes, in a high-throughput and miniaturized manner. Recently, numerous applicative efforts have been pursued generating disease-associated protein signatures that now could be further explored for improved disease diagnostics, prognostics and classification.
Body-coupled communications (BCC), in which the human body is used as a communications channel, has been shown to be a promising solution for wireless body-area networks (WBANs). For successful deployment of these BCC-based WBANs, it is necessary to develop a clear understanding of the channel behavior. Therefore, this paper presents the key characteristics of the capacitively-coupled on-body chan
We cannot directly uncover the contents of our mind but we can come closer to cognitive processes via overt manifestations. I am interested in how speakers perceive, conceptualise and spontaneously describe complex pictures on higher levels of discourse and I use eye tracking methodology along with verbal protocols and a multimodal scoring method to study these mental processes. In the studies on
The aim of the work presented in this thesis is the improvement of xylose fermentation performance of recombinant Saccharomyces cerevisiae strains expressing XYL1 and XYL2 from Pichia stipitis, encoding xylose reductase (XR) and xylitol dehydrogenase (XDH). A recombinant strain of S. cerevisiae, fermenting both xylose and glucose to ethanol could decrease the production cost of ethanol from ligno-

Reduced urinary bladder capacity is a clinically significant problem. The surgical methods that have been available to treat this, such as urinary diversion or surgically augmenting the bladder by incorporation of intestinal segments, all have serious drawbacks. There is a need to understand how the smooth muscle of the intestine and bladder can interact when brought into close contact surgically,
The Discrete Wavelet Transform (DWT) is a new way to analyze gas flow measurements in engine cylinders. The DWT technique differs significantly from the Fast Fourier Transform (FFT) in that with the former, the analysis of information can be done in both the time domain and frequency domain. The basic theory of wavelets is presented and the use of DWT is demonstrated on information derived from la
The purpose is to provide a brief overview of activities related to biofuels for transport in the Asia-Pacific Region, which covers a diverse range of countries and economies. The focus is on the Asia-Pacific Economic Cooperation (APEC),which is the premier forum for facilitating economic growth, cooperation, trade, and investment in the Asia-Pacific Region. APEC provides a forum for cooperation o
