In the present study, a new and versatile liquid-phase microextraction method is described. This method requires very simple and cheap apparatus and also a small amount of organic solvent. Eight microliters of 1-undecanol was delivered to the surface of solution containing analytes and solution was stirred for a desired time. Then sample vial was cooled by inserting it into an ice bath for 5 min.

This study evaluates factors involved at different stages in an IS outsourcing decision process. From a theoretical perspective, the motivation for IS outsourcing is often described as a result of three factors: cost reduction, access to technological expertise and focus on core competence. The aim of this paper is to evaluate motivational factors in an outsourcing decision process. The study uses

The Swedish business angel market of 2004 is presented and compared to that of 1992 in order to determine the significance of the time factor. The presentation is carried out against the background of the macroeconomic changes that have taken place and how they have affected the informal venture capital market. The empirical findings reveal how the amounts invested have changed, which companies th

We study the pointwise behavior of Birkhoff sums S(n)phi(x) on subshifts of finite type for Holder continuous functions phi. In particular, we show that for a given equilibrium state mu associated to a Holder continuous potential, there are points x such that S(n)phi(x) - nE(mu)phi similar to an(beta) for any a > 0 and 0 < beta < 1. Actually the Hausdorff dimension of the set of such points is bou

This was the second nordic seminar on moisture transport. The first meeting was held in Kopenhagen-Lyngby in 1989. The majority of the researchers who met in Ystad works with building materials at Technical Institutes or Universities in Denmark, Finland, Norway and Sweden. We discussed different aspects of moisture transport, including: • non-isothermal conditions • moisture flow at surfaces • dif

We describe a very efficient method for fluorescent labeling of acidic structures in denervated skeletal muscle with rhodamine B. Rhodamine B at 50 ng/ml gave selective and distinct segmental labeling of denervated muscle fibers after 5-min incubation at room temperature. Labeling was also achieved at 4 degrees C. The labeling was disrupted by the ionophores monensin and nigericin, suggesting a la

Popular Abstract in Swedish Satser i objektsposition i modern standardarabiska. MODERN STANDARDARABISKA Arabiska talas idag av ca 200 miljoner människor från Marocko och Mauretanien i väster till Irak och Oman i öster. De talade varianterna av språket skiljer sig åt ganska mycket, men man har ett gemensamt skriftspråk. Den moderna varianten av skriftspråket kallas ofta modern standardarabiska ocThis dissertation comprises a corpus-based study of the form and function of sentential object complements in Modern Standard Arabic (MSA). The study is motivated by the scarcity of investigations into MSA syntax as opposed to the syntax of Classical Arabic. Complements to three classes of complement-taking predicates (CTPs) ­ manipulation, cognition and utterance ­ are considered. The major part

To study the in vitro activity of imipenem, meropenem and ertapenem against common pathogens isolated from patients in intensive care, haematology and dialysis/nephrology units at 7 Swedish university hospitals, a total of 788 isolates were collected during 2002-2003. The distribution of the isolates was as follows: Escherichia coli (n = 140), Klebsiella spp. (n = 132), Proteus spp. (n = 97), Ente

Man kan identifiera fem stora kundsegment på energimarknaden, nämligen hushåll i småhuslägenheter, hushåll i flerbostadshusens lägenheter, fastighetsägare till flerbostadshus, unga hushåll samt medelålders och äldre hushåll. Jämfört med energiföretagens andra kundsegment inom exempelvis industri, handel, service eller myndigheter är hushållssegmenten oorganiserade. De innehåller många hushåll med

This thesis treats the problem of direct adaptive control of linear multivariable systems. The parametrization problem of adaptive control is discussed extensively. A pole-placement problem and a model-matching problem are formulated and interpreted in terms of model reference control. The problem is solved via a discussion on system invariants of multivariable systems as presented by Pernebo. The

The energy band structure of superconducting (T-c(onset) = 80 K), low-dimensional Sr(Ca)CuO2 single crystals was studied by photoelectron spectromicroscopy. The sample consists of double parallel Cu-O chains, and spectra show a strong anisotropy for electron momenta k parallel and perpendicular to the chain direction q. Spectra were collected with two experimental setups: kparallel toq (Aperpendic

This report shows examples of the scale factors used in a previously published semi-empirical tire-model, developed at the Department of Automatic Control in Lund. The scale factors are plotted as 3d surface diagrams depending on the longitudinal and lateral slip for a few different camber angles and velocities.
