Frontal eyes of crustaceans (previously Called nauplius eye and frontal organs) are usually simple eyes that send their axons to a medial brain Centre in the anterior margin of the protocerebrum. Investigations of a large number of recent species within all major groups of the Crustacea have disclosed four kinds of frontal eyes correlated with taxonomic groups and named after them as the malacostr
En fältstudie på åtta mastarbetare utfördes under februari i Svealand och Norrland. Mastarbetarnas aktiviteter observerades under en vanlig arbetsdag i masten och hudtemperaturen på sju ställen på kroppen, kroppstemperatur och hjärtfrekvens registrerades kontinuerligt. De fick också skatta sin temperaturupplevelse och ansträngningsgrad flera gånger under dagen. Lufttemperaturen varierade mellan -1Désirée Gavhed, Kalev Kuklane, Ingvar Holmér. Work on masts in cold conditions. Arbetslivsrapport 1999:22. Eight tower operators were studied in February during their ordinary duties in masts in four regions of Sweden. The activities of the workers were observed during a full working day and the skin temperature at seven spots, body temperature and heart rate were measured continuously. They also
To determine the additional stabilizing effect of unilateral hip fixation on external lumbar supports, nine patients with a posterolateral lumbosacral fusion without internal fixation were examined by roentgen stereophotogrammetric analysis. The roentgen stereophotogrammetric analysis was performed with the patients in supine and erect positions 1 month after surgery, that is, before fusion consol
A second workshop on small-x physics, within the Small-x Collaboration, was held in Lund in June 2002 with the aim of over-viewing recent theoretical progress in this area and summarizing the experimental status.
Blood samples from 141 children and adolescents were used to evaluate differences between commercial kits and radioimmunoassay (RIA) methods for detecting thyroid autoantibodies. Thyroglobulin autoantibodies (Tg-Ab) were analyzed with a hemagglutination kit and a RIA; thyroid peroxidase autoantibodies (TPO-Ab) were measured with a gelagglutination assay and a RIA. The result; of the antibody tests
The effects of two sympathomimetic drugs on mucociliary activity and mucosal blood flow in the rabbit maxillary sinus were investigated by using a photo-electric technique (mucociliary activity) and laser Doppler flowmetry (blood flow). The responses produced were compared with effects of ligation of the external carotid artery. The alpha 1-agonist phenylpropanolamine (0.1-100 micrograms/kg) had n
BACKGROUND: Active smoking is the most important risk factor for pulmonary emphysema in subjects with severe alpha 1-antitrypsin (AAT) deficiency. The aim of this study was to analyse the effects of environmental risk factors other than active smoking on lung function and on respiratory symptoms in non-smoking PiZZ individuals. METHODS: Lifetime exposure to passive smoking, domiciliary use of a ke
This article focuses on assessment deliveries in discussions on progress, i.e. when the teacher reports on his/her fellow-teachers’ assessments. In these episodes, the teacher runs the risk of ending up in a complicated situation, essentially since the assessments recurrently are very brief and/or difficult to interpret. To meet these problems, the teacher make use of certain strategies, e.g., add
Popular AbstractDen nya världsordningen som Castells kallar för nätverksamhälle skapar en konflikt mellan globalisering och identitet. I detta avseende blir frågan om identitet och etniska gränser, i Barths mening, ett centralt tema för att förstå samhällsförändringar. Globaliseringsprocessen håller på att skapa en försvagning av det civila samhället och med detta försvagas också förhållandena melThe new world order, that Castells denominates network society, generates a conflict between the globalisation and identity. In this sense the questions of identity and ethnic boundaries,in Barth’s meaning, emerge as a central subject to understanding societal changes. Globalisation is causing a weakening of the civil society, the relationship between the nation state and the people is also debili
The objective of this study was to investigate whether the appearance of virtual human models influences observers when judging a working posture. A task in which a manikin is manually assembling a car battery was used in the experiment. In total, 16 different Pictures were presented to the subjects. All pictures had the same background, but included a unique posture and manikin appearance combina

Rubidium concentrations in tissues of organisms (vascular plants, fungus, insect, bird, rodents) were closely related to soil chemical properties (K+ saturation as % cation exchange capacity, and pH) at repeated sampling of 30 beech forest sites in south Sweden. The Rb+ concentration of organisms, representing a variety of tropic levels, was a sensitive measure of the K+ status of acid soil ecosys
Popular Abstract in Swedish Diabetes karakteriseras av kroniskt förhöjt blodsocker som beror på bristande insulininsöndring och/eller bristfällig känslighet för insulin i kroppens vävnader. Diabetes kan indelas i olika typer beroende på orsak (etiologiskt typ). Förutom tidigare kända typ 1 och typ 2 diabetes finns nu även väl kända mindre vanliga former av diabetes där den bakomliggande genförändrDiabetes mellitus is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. The new WHO criteria for classification of diabetes takes into account also clinical stages dividing the diabetic patients into noninsulin requiring (NIR), insulin requiring for control (IRC) and insulin requiring for survival (IRS) subgroups.

Measurements in a road tunnel in Stockholm, Sweden give the real-world traffic emission factors for a number of gaseous and particle pollutants. These include 49 different polycyclic aromatic hydrocarbons (PAH), CO, NOX, benzene, toluene, xylenes, aldehydes, elements and inorganic/organic carbon contained in particles, the sub-micrometer aerosol number size distribution, PM2.5 and PM10. The exhaus
The development of robotized welding is truly impressive and is today one of the major application areas for industrial robots. The first industrial robots were introduced in the early 1960s for material transfer and machine tending. Not long after that, robots were used for spot welding and in the early 1970s for arc welding as well. During the years, significant developments have taken place bot
Popular Abstract in Swedish Vid blodbrist till en del av hjärtmuskeln, t.ex. vid ett stopp i ett av hjärtats kranskärl, kommer delar av hjärtmuskeln att vara utsatt för risk att drabbas av infarkt. Hjärtinfarkt definieras som döda hjärtmuskelceller. Det är av stor vikt för en patient med kranskärlssjukdom att man kan skilja de delar av hjärtmuskeln som drabbats av infarkt ifrån de delar som inte dBoth presence and extent of myocardial infarction are important prognostic factors for mortality and quality of life in patients with ischemic heart disease. Thus, it is of great clinical importance to be able to diagnose and characterize myocardial infarction. One way to diagnose myocardial infarction is by using the 12-lead electrocardiogram(ECG). For estimation of infarct size and location from
Two sets of experimental data on flame length under flat ceilings from a burner in a lower corner of a room have been correlated by conventional dimensionless variables. The correlations are shown to have considerable similarity to those of temperature distributions under ceilings caused by a heat source below. Matching is effected by a choice of temperature rise of approximately 180ºC.
About 25% of C2-deficient homozygotes have increased susceptibility to severe bacterial infections. C2-deficient homozygotes had significantly lower serum levels of IgG2, IgG4, IgD, and Factor B, significantly higher levels of IgA and IgG3 and levels of IgG1 and IgM similar to controls. Type I ( 28 bp deletion in C2 exon 6 on the [HLA-B18, S042, DR2] haplotype or its fragments) and type II ( non-t
Transition isotope shifts of 3s-3p transitions in Ne II and Ne III are measured in Fourier transform spectra from a hollow-cathode source. Accurate absolute line-center positions of the Ne-20 isotope are derived for the purpose of tertiary wavelength standards in the region 2000-5000 angstrom. A robust statistical treatment is applied, yielding line-position uncertainties that are lower than for t
