Aim The aim of this work was to estimate on a regional scale the effects of nitrogen (N) deposition and harvest intensity on N-budgets in forest soils as a basis for strategies of emission reduction and sustainable forest management methods. Location The calculations were applied to Sweden, a country with a managed forest area of 23 x 10(6) ha. Methods Mass balance calculations, including N-deposi

Popular Abstract in Swedish Avhandlingens syfte är att lyfta fram och analysera tre viktiga ämnen inom inombranschhandel; relevansen för efterfrågemönster, distinktionen mellan horisontell och vertikal inombranschhandel, och mätmetoden av inombranschhandel. Kapitel två analyserar inombranschhandel mellan hög- och låginkomstländer, och använder ett teoretiskt ramverk som förklarar bytet av liknandThis thesis aims at shedding light on three important issues related to intra-industry trade (IIT); the relevance of demand patterns, horizontal versus vertical IIT, and the measurement of IIT. Chapter two analyses IIT between high and low-income countries, and uses a theoretical model that explains the exchange of similar products of different qualities. We are particularly interested in the rol

Islet cell autoantibodies are strongly associated with the development of type 1 diabetes. The appearance of autoantibodies to one or several of the autoantigens—GAD65, IA-2, or insulin—signals an autoimmune pathogenesis of ß-cell killing. A ß-cell attack may be best reflected by the emergence of autoantibodies dependent on the genotype risk factors, isotype, and subtype of the autoantibodies as w

A novel type of bioelectronic region ion sensitive field effect transistor (RISFET) nanosensor was constructed and demonstrated on two different sensor chips that could measure glucose with good linearity in the range of 0-0.6 mM and 0-0.3 mM with a limit of detection of 0.1 and 0.04 mM, respectively. The sensor is based on the principle of focusing charged reaction products with an electrical fie

This study was undertaken to determine the value of stained smears from the vaginal introitus and the posterior vaginal fornix for detection of candida morphotypes in the diagnosis of recurrent vulvovaginal candidosis (RVVC) in cases with an assumed novel attack of the condition, and to compare the value of microscopy of such smears in relation to candida culture, vaginal pH-determinations and leu

Popular Abstract in Swedish Vad betyder ordet "hund"? Eller orden "ljudpinne", "måste", "gurka" och "röd"? Till skillnad från många tidigare forskare ser jag orden och våra språkliga uttryck som reaktioner på när saker och ting har blivit fel i våra vardagliga handlingar: anledningen till att jag måste ha ett ord för "röd" är att du kanske tog den blå skjortan i stället för den röda, och den passaWhat is the relation between the words in language and our everyday actions? Are linguistic structures dependent on our actions, or does language function on its own? This thesis deals with the pragmatic foundations of language and proposes a model of meaning in language that is based on our expectations about the world and about other people. On this view, language is seen as composed of three f

An analytic solution of the Brinkman and Stokes equations for a rigid sphere surrounded by a porous shell in pure straining flow is presented. The solution permits for an analytic determination of the intrinsic viscosity in the dilutelimiting expansion for the steady shear viscosity. The porous layer, characterized by a thickness and a constant permeability, alters the intrinsic viscosity from the

OBJECTIVE: To assess the prevalence of primary hip osteoarthritis (OA) in Iceland. To compare the prevalence of primary hip OA in Iceland with published rates of primary hip OA for related Scandinavian populations.METHODS: Roentgenographs were examined of 1530 Icelandic people 35 years or older (653 males, 877 females) subjected to colon radiography during the years 1990-1996. The radiographs exam

A study has been made of the mechanism of action of intradiscal injections of preparations of chymopapain in the treatment of sciatica. Such preparations were found to contain at least four distinct proteins, but enzymatically active chymopapain was the component mainly responsible for releasing glycosaminoglycan from cartilaginous tissue. Previous suggestions that an electrostatic interaction bet

Linear multistep methods (LMMs) constitute a class of time-stepping methods for the solution of initial value ODEs; the most well-known methods of this class are the Adams methods (AMs) and the backward differentiation formulae (BDFs). For the fixed stepsize LMMs there exists an extensive error and stability analysis; in practical computations, however, one always uses a variable stepsize. It is w

BACKGROUND: The diagnostic utility of magnetic resonance imaging in dementia workups has increased recently. The basic use is to exclude space-occupying processes in the brain. However, magnetic resonance imaging offers major opportunities for studying atrophy of specific brain areas. A great interest has been put in whether atrophy in the medial temporal lobe can serve as an early diagnostic mark

Using a generic electromagnetic model based on the spherical vector harmonics, we provide the Cramer-Rao lower bound (CRB) for direction-on-arrival (DOA) and polarization estimation with arbitrary multiport antennas. By reciprocity, the receiving multiport antenna is characterized in terms of the transmission matrix from incident voltage waves to multipole coefficients of the outgoing spherical ve

Sexual dimorphism is widespread in lizards, with the most consistently dimorphic traits being head size (males have larger heads) and trunk length (the distance between the front and hind legs is greater in females). These dimorphisms have generally been interpreted as follows: (1) large heads in males evolve through male-male rivalry (sexual selection); and (2) larger interlimb lengths in females
