This study examines aspects of scholarly journal publishing in the Nordic countries. On average half of Nordic journals publish online. In most Nordic countries, commercial publishers predominate; however, in Finland the majority are society publishers. The number of open access journals is low, in line with international figures. There is concern to maintain local languages in journal publishing.
Low molecular weight organic carbon compounds are potentially important carbon and energy substrates to heterotrophic production in the aquatic environment. We studied the occurrence of dissolved free amino acids (AA), monosaccharides (CHO), and carboxylic acids (CA) in the subarctic Lake Diktar-Erik. The lake is unproductive with slightly humic water, and receives water via one major inlet stream
The commutative algebra of invariants of a Lie super-algebra need not be affine, but does have a common ideal with an affine algebra, in all the known examples. This leads us to extend a class of algebras C to a class which we call "nearly C", by admitting those algebras C having a common ideal A with an algebra (containing C) in C such that C/A is an element of C. We generalize this notion slight
PURPOSE: Gitelman's syndrome (GS) is an inherited autosomal recessive disorder due to loss of function mutations in the SLC12A3 gene encoding the Na-Cl co-transporter (NCCT), the target of thiazide diuretics. The defective function of the NCCT, which normally is expressed in the apical membrane of the distal convolute tubule in the kidney, leads to mild hypotension, hypokalemia, hyperreninemic hyp
We prove under quite general assumptions the existence of a bounded positive solution to the semilinear Schrodinger equation in R-n, n greater than or equal to 3. (C) 2004 Elsevier Ltd. All rights reserved.
In this paper we present two novel generic schemes for approximation algorithms for optimization NP-hard graph problems constrained to partial k-trees. Our first scheme yields deterministic polynomial-time algorithms achieving typically an approximation factor of k/log(1-is an element of)n, where k = polylog(n). The second scheme yields randomized polynomial-time algorithms achieving an approximat
Our aim was to quantify the intestinal metabolic fate of dietary alpha-ketoglutarate (AKG). Female pigs In = 6; 21 d old) were implanted with arterial, venous, portal and gastric catheters and an ultrasonic portal flow probe and fed a corn and soybean meal-based diet. On (t)he day of the experiment, the pigs received a 4-h intragastric infusion of sodium AKG at a rate equivalent to 0, 2.5, 5 or 10
The proliferation and differentiation of primitive hematopoietic cells is tightly controlled by a number of signaling pathways. Transient blockage or enhancement of these signaling pathways may provide a new approach to manipulate the proliferation and differentiation of primitive hematopoietic cells. Adenoviral vectors have in recent years emerged as powerful tools for transient gene expression i
We generated a mouse model with a conditional deletion of TGF-beta signaling in the neurons by crossing TGF-beta receptor I (T beta RI) floxed mice with neurofilament-H (NF-H) Cre mice. 35% of F1 conditional knockout (COKO) mice developed spontaneous squamous cell carcinomas (SCCs) in periorbital and/ or perianal regions. Transplantation of these tumors into athymic nude mice resulted in 62% tumor
Gene expression signatures consisting of tens to hundreds of genes have been found to be informative for different biological states. Recently, many computational methods have been proposed for biological interpretation of such signatures. However, there is a lack of methods for identifying cell signaling pathways whose deregulation result in an observed expression signature. We present a strategy
Surface proteins of Streptococcus pyogenes are important virulence factors. Here we describe a novel collagen-like surface protein, designated SclA (streptococcal collagen-like surface protein). The sclA gene was identified in silico using the Streptococcal Genome Sequencing Project with the recently identified protein GRAB as the probe. SclA has a signal sequence and a cell wall attachment region
Postural control ensures stability during both static posture and locomotion by initiating corrective adjustments in body movement. This is particularly important when the conditions of the support surface change. We investigated the effects of standing on a compliant foam surface using 12 normal subjects (mean age 26 years) in terms of: linear movements at the head, shoulder, hip and knee; EMG ac
Orientation can be difficult for nocturnal bird migrants at high northern latitudes because of the large changes of magnetic declinations, rapid longitudinal time-shifts experienced during a long-distance flight and the invisibility of stars during the polar summer. Both sunset cues as well as geomagnetic cues have been shown to be of great importance in the orientation system of Savannah sparrows
Background. Primary care doctors see patients from diverse cultural backgrounds and communication plays an important role in diagnosis and treatment. Communication problems can arise when patient and doctor do not share the same cultural background. Objective. The aim of this study was to examine how consultations with immigrant patients are understood by GPs and how GPs manage these consultation
Insect damage is a general problem that disturbs the growth of forests, causing economic losses and affecting carbon sequestration. Coarse-resolution data from satellites are potentially useful for national and regional mapping of forest damage, but the accuracy of these methods has not been fully examined. In this study, a method was tested for the mapping of defoliation in Scots pine [Pinus silv
