The Baltic Sea is one of many aquatic ecosystems that show long-term declines in dissolved silicate (DSi) concentrations due to anthropogenic alteration of the biogeochemical Si cycle. Reductions in DSi in aquatic ecosystems have been coupled to hydrological regulation reducing inputs, but also with eutrophication, although the relative significance of both processes remains unknown for the observ

In this paper I argue that EPP effects are of two different types, NP-movement and the Filled Left Edge Effect. While NP-movement is driven in Narrow Syntax by the computation of Person, some Filled Left Edge phenomena, including Icelandic Stylistic Fronting, seem to take place in PF. Even so, these phenomena also reflect the clausal computation, that is, the matching processes that value clause i

The aim of this project is to explore and understand the combustion phenomenon in engines operating on gaseous fuels, and develop technologies as an alternative to the present diesel engine technologies for heavy duty applications; which are facing severe challenges like stringent emissions norms, high technology costs and unsustainable fuel supply. The studies presented in this thesis focus on th

In automotive systems, some of the engine control tasks are triggered by specific crankshaft rotation angles and are designed to adapt their functionality based on the angular velocity of the engine. This paper proposes a new task model for specifying such a type of real-time activities and presents an approach for analyzing the system feasibility under dynamic scheduling for different scenarios.

Optical mapping by direct visualization of individual DNA molecules, stretched in nanochannels with sequence-specific fluorescent labeling, represents a promising tool for disease diagnostics and genomics. An important challenge for this technique is thermal motion of the DNA as it undergoes imaging; this blurs fluorescent patterns along the DNA and results in information loss. Correcting for this

LACM 128319, which was collected in western Kansas, U. S. A., and is assignable to Platecarpus tympaniticus (Mosasauridae, Plioplatecarpinae), represents arguably one of the most exquisite mosasaur specimens known to date. Measuring 5.67 m from the tip of the snout to the end of the tail, it comprises an exceptionally well-articulated skeleton, accompanied by soft-tissue remains, such as skin impr

Pathological complete response (pCR) following chemotherapy is strongly associated with both breast cancer subtype and long-term survival. Within a phase III neoadjuvant chemotherapy trial, we sought to determine whether the prognostic implications of pCR, TP53 status and treatment arm (taxane versus non-taxane) differed between intrinsic subtypes. Patients were randomized to receive either six cy

This paper presents a model of long waves and an empirical analysis of Swedish growth since 1850. The model emphasises the creation of new complementarities around macro innovations. The growth process is periodised in two main parts. The first period is characterised by transformation when development is uneven and unbalanced. The second period is characterised by rationalisation when the economy

Popular Abstract in Swedish Svår alfa-1antitrypsinbrist (AAT-brist), s.k. PiZZ, är ett ärftligt tillstånd som har en hög förekomst i Sverige, cirka 1/1600. Bristen innebär ökad risk för utveckling av kroniskt obstruktiv lungsjukdom (KOL), speciellt hos rökare. Leversjukdom är också relativt vanlig och kan förekomma såväl i barndomen som i hög ålder. Levercirros (skrumplever) och levercancer är öveSevere alpha-1 antitrypsin deficiency (AATD) is a genetic disorder associated with increases risk of developing of chronic obstructive lung disease and liver disease. The Swedish National Registry for individuals with severe AATD was started 1991.Up to October 2008, a total of 1349 individuals were included in the registry. The aims of the studies in this thesis which bases on AATD registry are to

This article should serve as an introduction to a relatively new topic in ethnological studies requiring very specific methods as it involves both offline and online research as well as material objects and immaterial practices. How do we embark on an interdisciplinary venture such as this, and be sure to produce qualitative research of high standard? How should gaming mothers best be studied? In

The structural characteristics of Ba-Fe double hydroxides were studied by various methods, such as scanning electron microscopy (SEM), energy dispersive X-ray (EDX) fluorescence and X-ray absorption spectroscopies (XAS). It was verified that under hyperalkaline conditions (using 10 M or 20 M NaOH solution for precipitating the substances) layered double hydroxides could be prepared and the structu

An introduction into the area of inverse problems for the Schrodinger operators on metric graphs is given. The case of metric finite trees is treated in detail with the focus on matching conditions. For graphs with loops we show that for almost all matching conditions the potential on the loop is not determined uniquely by the Titchmarsh-Weyl function. The class of all admissible potentials is cha

The effects of self-assembly on the hydrolysis kinetics of surfactants that contain ester bonds are discussed. A number of examples on how reaction rates and apparent reaction orders can be modulated by changes in the conditions, including an instance of apparent zero-order kinetics, are presented. Furthermore, it is shown that the examples on reaction kinetics display parallels and connections to

Background: The objective was to identify separate cognitive domains in the standard assessment tools (MMSE, ADAS-Cog) and analyze the process of decline within domains during three years in Alzheimer's disease (AD) patients with donepezil treatment. Method: AD patients (n = 421) were recruited from a clinical multi-centre study program in Sweden. Patients were assessed every six months during thr

The interaction of water vapor with ice remains incompletely understood despite its importance in environmental processes. A particular concern is the probability for water accommodation on the ice surface, for which results from earlier studies vary by more than 2 orders of magnitude. Here, we apply an environmental molecular beam method to directly determine water accommodation and desorption ki

The complex structural behavior of tau-[AgCu](similar to 0.92)V4O10 has been elucidated by single crystal X-ray diffraction and thermal analysis. The tau-phase region is apparently composed of several distinct phases and this study identifies at least three: tau(1rt) tau(2rt) and tau(1t), tau(1rt) and tau(2rt) have slightly different compositions and crystal habits. Both phases transform to Tit at

The interfacial behavior of aqueous solutions of four different neutral polymers in the presence of sodium dodecyl sulfate (SDS) has been investigated by surface tension measurements and ellipsometry. The polymers comprised linear poly(ethylene oxide) with low and high molecular masses (10 (3) and 10 (6) Dalton (Da), respectively), and two high molecular mass methacrylate-based comb polymers conta
