Modified stainless steel surfaces targeted to reduce fouling - Evaluation of fouling by milk components
Several stainless steel based surfaces with different properties were evaluated according to their fouling behaviour for different dairy products under different conditions. Surface properties were obtained by the following modification techniques: SiF3+, MoS22+ and TiC ion implantation; diamond-like carbon (DLC) sputtering; DLC, DLC-Si-O and SiOx, plasma enhanced chemical vapor Deposition (PECVD)
Recording of biosignals from the human uterus, a basis for the development of new therapies in preterm labour and primary dysmenorrhoea.
The stable pyrimidines UDPbetaS and UTPgammaS discriminate between the P2 receptors that mediate vascular contraction and relaxation of the rat mesenteric artery
The contractile and relaxant effects of the different P2 receptors were characterized in the rat isolated mesenteric artery by use of extracellular nucleotides, including the stable pyrimidines uridine 5'-O-thiodiphosphate (UDPbetaS) and uridine 5'-O-3-thiotriphosphate (UTPgammaS). The selective P2X receptor agonist, alphabeta-methylene-adenosine triphosphate (alphabeta-MeATP) stimulated a potent

Abstract in Danish Benign paroksysmal positionel vertigo viser sig ved kraftige rotatoriske svimmelhedsanfald, når patienten bevæger sit hoved i bestemte stillinger. Tilstanden er, som navnet udsiger, benign, men medfører oftest væsentlig morbiditet. Fritflydende otolitter (ørekrystaller) antages at sedimentere i buegangene ved hovedbevægelser. Herved påvirkes cupula hydrodynamisk og dette medføreBenign paroxysmal positional vertigo presents with brief, episodic, positioning-provoked vertigo and characteristic findings on Dix-Hallpike and other positional tests. This article is based on a systematic review of the literature and describes epidemiology, etiology, pathogenesis, diagnostic positional tests and treatment using canalith repositioning, liberatory and 360 degrees rotation manoeuvr
Hexafluorophosphates of chlorotris(dimethyl sulfide)platinum(II) and bromotris (dimethyl sulfide)platinum(II)
The title compounds, chlorotris(dimethyl sulfide-kappaS)platinum(II) hexafluorophosphate, [PtCl(C2H6S)3]PF6, and bromotris(dimethyl sulfide-kappaS)platinum(II) hexafluorophosphate, [PtBr(C2H6S)3]PF6, are isomorphous and are composed of [PtX(dms)3]+ complex cations (X = Cl and Br, and dms is dimethyl sulfide) and PF6- anions. The Pt atom is coordinated by three S atoms and one X atom in

Explorations in the New Economic Geography
Popular Abstract in Swedish Denna avhandling har den Nya Ekonomiska Geografin, ett mycket snabbt växande forskningsområde inom internationell ekonomi, som utgångspunkt. Avhandlingen består av fyra kapitel; det första är ett introduktionskapitel och de tre följande är teoretiska studier. Avhandlingen kan sammanfattas som följer. I kapitel ett ges en introduktion till forskningsfältet. Det nyspiranThe point of departure of this thesis is the rapidly growing research field known as the New Economic Geography (NEG). It consists of four chapters, one introductory chapter and three self-contained theoretical studies. The chapters may be summarised as follows. The first chapter gives a brief account of the NEG. It explains the soaring interest in the location of economic activity, and it review

Fungal biomass production and turnover in soil estimated using the acetate-in-ergosterol technique
We report the first attempt to estimate fungal biomass production in soil by correlating relative fungal growth rates (i.e., acetate incorporation into ergosterol) with fungal biomass increase (i.e., ergosterol) following amendments with dried alfalfa or barley straw in soil. The conversion factor obtained was then used in unamended soil, resulting in fungal biomass productions of 10–12 μg C g−1 s
The inverse scattering problem for a homogeneous bi-isotropic slab using transient data
Transient wave propagation in a finite bi-isotropic slab is treated. The incident field impinges normally on the slab, which can be inhomogeneous wrt depth. Dispersion and bi-isotropy are modeled by time convolutions in the constitutive relations. Outside the slab the medium is assumed to be homogeneous, non-dispersive and isotropic, and such that there is no phase velocity mismatch at the boundar
Dissociation of phosphorylase a activation and contractile activity in rat portal vein
Isometric force, glycogen phosphorylase activity and lactate production were measured under conditions known to alter intracellular Ca2+ and cAMP to assess the role of these messengers in the coordination of metabolism with contractility in rat portal vein. Total phosphorylase (a + b) activity, was independent of treatment. The activity ratio phosphorylase activity ratio in the presence of isoprot
Approximation algorithms for optimization problems in graphs with superlogarithmic treewidth
We present a generic scheme for approximating NP-hard problems on graphs of treewidth k = omega (log n). When a tree-decomposition of width l is given, the scheme typically yields an l / log n-approximation factor; otherwise, an extra log k factor is incurred. Our method applies to several basic subgraph and partitioning problems, including the maximum independent set problem.
Flödesanalys i den hållbara utvecklingens tjänst - Reflektioner kring en "metabolism"-studie av Rhenområdets utveckling
The objective of this study is to contribute to the discussion about linking society and nature in environmental research. It is an attempt to provide a critical analysis of the "Industrial Metabolism" studies, which have been based on a flow perspective and have argued that such a perspective is essential to the search for environmentally sustainable societal development paths and could serve as
In-vitro release of bupivacaine from injectable lipid formulations investigated by a single drop technique--relation to duration of action in-vivo.
The aim of this study was to develop an in-vitro release method suitable for injectable slow-release lipid formulations of local anaesthetics (or other drugs). We also aimed that the results of the in-vitro measurements should have a clear relationship to duration of action in-vivo. Six formulations of bupivacaine base in medium-chain triglyceride-glyceryl dilaurate mixtures were developed. A new
Overexpression of cyclin D1 correlates with sensitivity to cisplatin in squamous cell carcinoma cell lines of the head and neck
Objective-Treatment strategies for squamous cell carcinoma of the head and neck (SCCHN) are based on the TNM classification. Biological markers that can predict the response to therapy have so far not been introduced. The objective of this study was to investigate cyclin D1 deregulation relative to sensitivity to cisplatin. Material and Methods-This was a laboratory study of 23 established Univers

The Materiality of Territorial Production - A Conceptual Discussion of Territoriality, Materiality and the Everyday Life of Public Space
This article brings together research on territoriality and actor-network theory in order to develop new ways of investigating the role of materiality and material design in the territorial power relations of urban public places. Using the public square as a main example, I suggest some new ways of conceptualizing the production and stabilization of territories in the everyday urban environment. S
beta-Glucan incorporated into a fruit drink effectively lowers serum LDL-cholesterol concentrations
Background: beta-Glucan can reduce serum concentrations of total and LDL cholesterol. The mechanism of this action is not clear, however, and it is difficult to predict the cholesterol-lowering effect of a food product enriched with beta-glucan. Objectives: We examined the effects of a beta-glucan-enriched fruit juice on serum lipids and lipoproteins and on markers of cholesterol absorption (serum
