The karyotypes (number, morphology and size of the chromosomes) of two algae species of Scenedesmus genus, S. incrassatulus and S. antennatus, were studied. The karyotype of S. incrassatulus (n=4) was asymmetric, characterized by two large metacentric, one large submetacentric and one small metacentric chromosomes. The karyotype assembly of S. antennatus (n=6) reveals two metacentrics and four sub
Software release planning can be described as a process consisting of the following three phases: (i) strategic release planning, i.e., the assignment of features to subsequent releases; (ii) operational release planning, i.e., the allocation of resources to tasks within each individual release; and (iii) dynamic re-planning, i.e., the revision of plans in order to handle unexpected changes impose
BACKGROUND: Prognostic factors for metastasis in soft tissue sarcoma govern decisions regarding adjuvant treatment. However, the significance of initial tumor-related prognostic factors over time is largely unknown.METHODS: The current study included 338 patients with malignant fibrous histiocytoma (MFH) of the extremities or the trunk wall whose tumors were reviewed by the Scandinavian Sarcoma Pa
Modern industrial customers, such as pulp and paper industries, have increased the vulnerability to power quality problems. A voltage source converter based high-voltage direct current (VSC-HVDC) transmission has the potential to offer high power quality when transmitting large amount of power. Therefore, in this paper, a VSC-HVDC transmission is proposed to supply such industrial plants in order
In conjugated polymers the optical excitation energy transfer is usually described as Forster-type hopping between so-called spectroscopic units. In the simplest approach using the point-dipole approximation the transfer rate is calculated based on the interaction between the transition dipoles of two spectroscopic units. In the present work we compare this approach with three others: The line-dip
Access to Emergency obstetric care (EmOC) remains a challenge for women. This paper presents a summary of issues and suggestions from one of the working groups at the FIGO precongress workshop on access of sexual and reproductive health care in November, 2006, in Kuala Lumpur.
We have measured the proton recoil polarization in the He-4((e) over right arrow ,e(')(p) over right arrow)H-4 reaction at Q(2)=0.5, 1.0, 1.6, and 2.6 (GeV/c)(2). The measured ratio of polarization transfer coefficients differs from a fully relativistic calculation, favoring the inclusion of a medium modification of the proton form factors predicted by a quark-meson coupling model. In addition, th
The ELDCARE study aims to investigate, at the ecological level, the relationships between socio-economic variables and cancer survival in patients aged 65 years and over. Survival data for patients diagnosed during the period 1985-1989 and followed up to 1994 were provided by 43 European Cancer Registries in 16 countries participating in the EUROCARE 2 project. Relative survival was computed by Ha
Background & Aims: In the stomach, Helicobacter pylori is found both in the mucus layer and adhering to the gastric epithelium. The aim of this study is to characterize the binding of H. pylori to human gastric mucins. Methods:H. pylori strains that bind the Lewisb (Leb) structure (via the BabA adhesin) and/or sialylated structures, along with isogenic adhesion deletion mutants, were used to i
Forestry is of major economical importance in Europe, and recent devastating windstorms have pinpointed the vulnerability of this economic sector to windstorms. Forest damage is an important economic issue at a country level and may become even of larger concern under future conditions following global warming. An underlying question is to what extent the storm damage is due to changes in the wind
Four whole- lake inorganic C-13 addition experiments were conducted in lakes of differing trophic status. Inorganic C-13 addition enriched algal carbon in C-13 and changed the delta C-13- DOC by + 1.5 parts per thousand to + 9.5 parts per thousand, depending on the specific lake. This change in delta C-13- DOC represented a significant input of algal DOC that was not completely consumed by bacteri
The purpose of this study was to develop a new completely automated method for the interpretation of ventilation-perfusion (V-P) lung scintigrams for the diagnosis of pulmonary embolism. A new way of extracting features, characteristic for pulmonary embolism is presented. These features are then used as input to a Support Vector Machine, which discriminates between pulmonary embolism or no embolis
Production of various proteins can today be made using genetically modified Escherichia coli bacteria. In cultivations of E. coli it is important to avoid accumulation of the by-product acetate. Formation of acetate occurs when the specific glucose uptake exceeds a critical value and can be avoided by a proper feeding strategy. A difficulty is that the critical glucose uptake often is poorly known
We investigated the protection from photoinhibition by different developmental stages of Haematococcus lacustris [Girod] Rostafinski using chlorophyll fluorescence measurements of single cells and suspensions. An overall correlation between higher cellular content of secondary carotenoids and the capacity to withstand excessive irradiation was observed in flagellated cells and aplanospores of H. l
Salmonid parr-smolt transformation (smoltification) is a transitional stage between freshwater and seawater life when the salmon imprint on their natal stream, change from a territorial feeding behavior to downstream migration, increase their hypoosmoregulatory competence, and change body shape and coloration. Photoperiod is recognized as the most potent initiator and regulator of the smoltificati
Severity assessment of patients with haemophilia A (HA) is traditionally based on FVIII activity (FVIII:C). Clinical phenotype of HA patients often differs between individuals with the same FVIII:C determined with clotting and chromogenic assays. The aim of this study was to assess the influence of the FVIII:C on thrombin generation (TG) assay parameters both in vitro and ex-vivo postinfusion plas
Loess soils cover vast areas in the arid and semi-arid regions of northern China. Due to the lack of reliable surface water and ground-water, rainwater harvesting has played a prominent role in farmers' domestic usage and agricultural irrigation. An economical arid valid type of water storage cistern with optimum design of components has been introduced to rural areas in the Loess Plateau. Differe
A fragment of the mitochondrial cytochrome b gene of avian malaria (genera Haemoproteus and Plasmodium) was amplified from blood samples of 12 species of passerine birds from the genera Acrocephalus, Phylloscopus and Parus. By sequencing 478 nucleotides of the obtained fragments, we found 17 different mitocholdrial haplotypes of Haemoproteus or Plasmodium among the 12 bird species investigated. On
In order to correlate behavioural deficits to lesion size and to reveal possible functional asymmetries in the rat brain, locomotor activity, rotation and sensorimotor integration to touch were studied in spontaneously hypertensive rats (SHR) subjected to right or left middle cerebral artery occlusion. Control and infarcted rats showed no difference in locomotor activity. Infarcted rats tended to
