Syftet med denna studie är att beskriva etanols energieffektivitet och klimatnytta och hur dessa parametrar beror av lokala förutsättningar och beräkningsmetodik. Andra aspekter som påverkan på biologisk mångfald, arbetsmiljöförhållanden mm analyseras ej här. Fokus ligger på svensk spannmålsbaserad etanol men kopplingar görs till andra produktionssystem för etanol. Hur klimateffektiv etanol är som
The Canons of Dalby. Three Studies I. When did the brothers in Dalby become Augustinians? There are different opinions among historians about what kind of community Egino founded in Dalby in the late 1060s. Some say it was Benedictine, others say it was a community of canons. Among the latter, some say they were regular canons, others that they were secular, and one distinguished historian has ev
The reaction rate coefficient k(CH3Br + OH) has been determined in the temperature range 298-373 K, using pulse radiolysis/UV kinetic spectroscopy, and at 298 K using a relative rate method. The Arrhenius expression obtained from a fit to the experimental results is (2.9 +/- 0.9) x 10(-12) exp(-(1230 +/- 125)/T) cm(3) molecule(-1) s(-1), which is greater than the expression currently recommended.
We proposed a 4×8 array antenna with aperture-coupled patch antenna elements. The antenna was designed for 60 GHz operation and fabrication on the low-temperature cofired ceramic(LTCC) substrate(εr=5.8). The feedline with the stub was designed to enhance the radiating element bandwidth and the transition characteristics between the waveguide (WG) and microstrip line(MSL). Through the optimization
Popular Abstract in Swedish Gliom är den vanligaste typen av hjärntumörer hos vuxna. Den mikroskopiska klassificeringen av de olika formerna av gliom är subjektiv och i vissa fall t.o.m. felaktig, vilket leder till klinisk oklarhet som kan hindra utvecklingen av terapier som riktas mot speciella egenskaper som kännetecknar speciella typer av gliom. EGFR och PDGFRA är en cellreceptor som har en cenGlioma is the most common type of primary tumor in the adult central nervous system (CNS). However, the current classification of gliomas is highly subjective and even inaccurate in some cases, which leads to clinical confusion and hinders the development of targeted therapies. EGFR and PDGFRA play crucial roles in glia development and glioma pathogenesis. In this thesis we aim to establish a glia
In mammals, including humans, the most consistent cognitive sex difference appears to be a male advantage in spatial ability. Usually, some sex-correlated selective advantage is inferred to explain this, for example, the need for males to navigate over large territories. In birds, sex differences in learning abilities are rare. Here, we show that females of a common European songbird, the great ti
Background: The kidneys are regarded as one of the main dose-limiting organs in the treatment of neuroendocrine tumours with Lu-177-[DOTA(0), Tyr(3)]-octreotate (Lu-177-octreotate), despite the successful use of kidney uptake blocking agents such as lysine and arginine. To avoid renal toxicity but still give each patient as high amount of Lu-177-octreotate as possible, there is a need for methods/
Blue emitting phosphors are investigated and reported for possible use in thermometry. Currently reported thermographic phosphors in general have the drawback of long emission lifetimes obstructing the possibility to time gate for background discrimination. An additional problem is that many thermographic phosphors have emission in the red spectral region, making them vulnerable for black body rad
Abstract in UndeterminedPurpose:This study explores the possibilities of transferring peripheral tactile stimulations from an artificial hand to the forearm skin.Method:A tactile display applied to the forearm skin was used to transfer tactile input to the forearm from various locations on a hand displayed on a computer screen. Discernment of location, levels of pressure and a combination of the t
The aim of this study was to investigate the effects of salting and different pre-salting procedures (injection and brining versus brining only) on the microstructure and water retention of heavy salted cod products. Salting resulted in shrinkage of fibre diameter and enlargement of inter-cellular space. Water was expelled from the muscle and a higher fraction became located in the extra-cellular
Traditional, pre-industrial farming was adapted to the natural environment-topography, geology, hydrology, climate, and biota. Traditional land use systems are still to be traced in Scandinavia as an "infield/outland landscape", and in Japan as a "Satoyama landscape." There are obvious similarities and differences in land use-the main difference being that pasturing of cattle and sheep has been le
Introduction and purpose In recent years, there has been renewed interest in using unicompartmental knee arthroplasty (UKA). Several studies have reported increasing numbers of UKAs for osteoarthritis in patients who are less than 65 years of age, with low revision rates. To describe and compare the use and outcome of UKA in this age group, we have combined data from the Australian and Swedish kne
Objective: To build on Achenbach, Rescorla, and Ivanova (2012) by (a) reporting new international findings for parent, teacher, and self-ratings on the Child Behavior Checklist, Youth Self-Report, and Teacher's Report Form; (b) testing the fit of syndrome models to new data from 17 societies, including previously underrepresented regions; (c) testing effects of society gender, and age in 44 societ
The past years have seen increasing interest in nonlinear optical microscopic imaging approaches for the investigation of diseases due to the method's unique capabilities of deep tissue penetration, 3D sectioning and molecular contrast. Its application in clinical routine diagnostics, however, is hampered by large and costly equipment requiring trained staff and regular maintenance, hence it has n
Developmental and comparative studies of the ability to understand communicative intentions using object-choice tasks raise questions concerning the semiotic properties of the communicative signals, and the roles of rearing histories, language and familiarity. We adapted a study by Tomasello, Call, and Gluckman (1997), in which a “helper” indicated the location of a hidden reward to children of th
Agrarian history and local cultural landscape dynamics have been documented through pollen analysis of a peat core within the hamlet of Yttra Berg, which is situated in an upland area of southwest Sweden. The sequence covers the last 5,000 years, from Neolithic to modern time. Wood pasturing started at 2000 b.c., followed by grazing and small-scale cultivation with 500 year cycles from 650 b.c., a
Purpose - One current trend in burner technology is to obtain high efficiency while keeping low levels of NOx emissions. A swirling flow in combustion ensures a fixed position of a compact flame. Therefore, it is necessary to design efficient swirlers. Flow patterns are simulated for the different swirl devices proposed in this work. Two axial-swirlers are studied: one based on curve-vanes consist
