Geotechnical engineering is the science dealing with mechanics of soils and rocks and its engineering applications. Geotechnical engineering projects vary in a wide range, from evaluation of the stability of natural slopes and man-made soil deposits, to the design of earthworks and foundations. Traditional methods, using manual calculations or simplified computational methods, do not, as a rule, t
The paper/presentation gives an overview of Peer-Assisted Study Schemes (SI-PASS) in Higher Education in Europe. SI-PASS is a method of improving student performance in “difficult” courses combining “how to learn” with “what to learn”. SI-PASS sessions are scheduled parallel to the regular education and are guided and facilitated by a “senior” student, the SI-PASS leader. The sessions are based on
IntroductionConsidering that on average in developed countries we spend about 65% of our time in private homes, understanding the exposures in homes is of outmost importance. Aerosol concentrations indoors come from indoor sources, infiltrate from outdoors and can be formed from precursors both of indoor and outdoor origin. Several characteristics and processes influence the properties of aerosols
Innovation plays an important role in organization survival and longevity. This is especially true in the retail industry; there is a growing acknowledgment of the role of innovation in retail practice, as maintaining the status quo might prove insufficient, especially for traditional retailers, in addressing the enormous challenges they are facing driven by technological developments and evolving
The work presented here aims at producing hydrogen for proton-exchange fuel-cell applications from hydrocarbons. This thesis describes an integrated catalytic converter comprising a steam-reforming reactor (heat of reaction supplied by catalytic combustion), a water-gas shift reactor and a preferential oxidation of carbon monoxide reactor, and the work performed on the fuel processing catalysts th

The general and specific objectives of the research on the performance indicator framework were to: – Improve transparent
Popular Abstract in Swedish Denna avhandling presenterar resultat från experimentella studier av tensiders och enzymers beteenden vid modellytor. Ellipsometri var den i huvudsak använda tekniken i dessa undersökningar. Studier av tensidadsorption i statiska och dynamiska vätningssituationer initierades för att undersöka adsorptionsbeteenden i närheten av trefaslinjen under dynamisk vätning. I falThis thesis presents results from experimental studies of the interfacial behaviour of surfactants and enzymes at model surfaces. The main technique used throughout the work was ellipsometry. Studies of surfactant adsorption in static and dynamic wetting situations were performed to investigate adsorption behaviour close to the three-phase contact line (tpl) during dynamic wetting. It was demonst
Popular Abstract in Swedish Fotosyntesen är nödvändig för vårt liv på jordklotet. Fotosyntes utförs huvudsakligen av gröna växter och dessutom av vissa bakterier. Dessa organismer absorberar energin i solljuset och omvandlar den till kemisk energi i form av till exempel kolhydrater och fett som vi människor och djur sedan kan förbränna och utvinna energi ifrån. Fotosyntesen utförs av ett flertal pPSII catalyses the light-induced water splitting process which leads to electron transfer through the thylakoid membrane and formation of energy rich molecules. Several redox components including a Mn4Ca, an amino acid residueYZ, two special Chl molecules P680, two Pheo and two quinone molecules participate in this process. Another component of PSII which interacts magnetically with Mn4Ca is D2-Ty
The starting point of this study is the striking similarities between late modern notions of anthropogenic climate change and premodern ideas about divine punishment. In both these cases the occurrence of future disasters have been directly linked to the moral behavior of the endangered. What threatens to befall man is considered to be his own fault. Hence urgent calls have been made for each and
The current form-giving activity in industrial design is characterized by explorations that depend on the individual capability to mentally manipulate a solution space from which to select and express the intended result. Designers often rely on artistic experimentation, aesthetic inspiration, or product specifications. These approaches often lead to satisfactory results, but they could be augment
Breast cancer is a truly heterogenous disease, reflected in the existence of a wide spectrum of phenotypic subsets of tumours with varying intrinsic aggressiveness as well as ability to respond to a given treatment. Recent advances in large-scale genomic and proteomic screening techniques have confirmed this heterogeneity also at a molecular level, but there is still a bottleneck to be overcome be
In order to simplify and/or improve determination of glomerular filtration rate (GFR) the clearances of iohexol, 51Cr-EDTA and endogenous creatinine were simultaneously determined with different techniques in 21 anesthetized landrace pigs. Their GFR had been reduced to about 1/3 or less of normal GFR. After an intravenous bolus of the GFR markers, their plasma concentration curves were followed fo
Popular Abstract in Swedish Proteoglykaner (PG), framför allt sådana som bär glykosaminoglykan-sidokedjor av heparansulfat (HS) typ, utgör multifunktionella receptorer på cellytan och i pericellulär matrix hos alla adherenta celler i högre organismer. HS-proteoglykaner är inblandade i många olika cellprocesser, bl.a. koagulation, celltillväxt, och aktivering av enzymer, antienzymer samt bindning tThe present investigation focuses on the role of HS metabolism in cell proliferation. The effect of the HS priming ß-D-xyloside, 2-(6-hydroxynaphthyl)-O-ß-D-xylopyranoside (Xyl-2-Nap-6-OH) on the proliferation of normal and transformed cells was studied. Xyl-2-Nap-6-OH inhibited growth of transformed cells to a significantly greater extent than normal cells. The growth inhibition exerted by the xy
Popular Abstract in Swedish Mag-tarmkanalen utgör kroppens största hormon-producerande organ. Många av de hormon-producerande cellernas funktion är ännu okänd och mycket lite är känt om den betydelse de kan ha vid olika sjukdomar i mag-tarmkanalen. I magsäckens syraproducerande del (fundus) finns 4 hormon-producerande celler, av vilka ECL cellen (65 %) och A-lika cellen (25 %) tillsammans utgör caThe ECL cells constitute a prominent endocrine cell population in the acid-producing part of the stomach. They are controlled by circulating gastrin released from G-cells in the antrum. In response to gastrin, they secrete histamine, that in turn stimulates the parietal cell to secrete acid. The first aim of the study was to prepare isolated ECL cells of high purity and to study and identify regul
Amelogenin is an extracellular matrix protein involved in formation of enamel during early tooth development. By interacting with the forming enamel crystallites amelogenin affects their growth, so that highly elongated hydroxyapatite crystals are formed. Early during the enamel formation amelogenin is proteolytically processed, which is essential for correct enamel formation. However, the exact m
This thesis is based on three scientific papers dealing with different models for coordinated control of multi-stage inventory systems. The ability to control multi-echelon inventory systems, is paramount for reducing tied up capital and inventory costs in large distribution systems. It is also one key issue in achieving efficient supply chain management. We focus our attention on a general distr
The transfer of 210Po and 210Pb between various compartments in the terrestrial environment has been analysed by using various published data. The average activity concentration of 210Po in soil is 61 ± 14 Bq.kg-1 d.w. with a median (50%) value of 44 Bq.kg-1 d.w. Ground water concentrations of 210Po in drilled wells might be as high as 6.5 Bq/l. But in regular drinking water it is just about 3-5
Background: The observation of differences in the way apparently similar patients are treated from one health care setting to another, i.e., practice variation, have been recognized in numerous studies. The variations across the health care settings have been shown to exist for different outcomes. However, any measurement of any system will reveal some form of variation and this normal inevitable
I avtalsrätten utgörs en central princip av pacta sunt servanda – löften ska hållas. Denna princip, som på ytan kanske inte ser ut att innebära några svårigheter, kan leda till bekymmer sett inom ramen för användandet av letter of intent respektive letter of comfort. I det moderna näringslivet har ett flertal sätt att sluta kommersiella avtal vuxit fram och lett till att avtalslagens anbud-accepOne fundamental principle within the field of contract law is pacta sunt servanda - agreements must be kept. This principle, which on the surface might not seem very complicated, may cause problems when applied on the use of letter of intent and letter of comfort. In the modern business world several ways of entering commercial contracts have arisen, causing the offer-and-acceptance-model provide
Commitment to involuntary care is a multistage process comprising many different aspects; legal, psychological, medical, social and ethical among others. It can also be analyzed from the perspective of a continuum starting from the report to the social authorities, the evaluations on whether to commit or not, the actual commitment and aftercare following involuntary treatment.
