We present a semi-empirical equation for prediction of the strengths of those N III lines that are generated by the Bowen mechanism and observed in spectra of symbiotic stars. The equation assumes that the Bowen mechanism is the only source populating the 3d state in N III, and comparisons with observations of the 3s-3p and 3p-3d transitions serve as a test of this assumption. In an ongoing study
New mechanisms for respiratory chain complex III diseases have recently been reported. Deletions, rearrangements and tRNA mutations of mitochondrial DNA cause deficiencies in several complexes. Mutations in the only complex III subunit encoded by mitochondrial DNA, cytochrome b, cause variable clinical phenotypes, such as cardiomyopathy or multisystemic dysfunction after birth. The homozygous seri
The taxonomy of the dogroses (Rosa sect. Caninae) is notoriously problematic and all the members of the section are characterized by a form of unbalanced meiosis (so-called "canina meiosis"). We used a novel combination of random amplified polymorphic DNA (RAPD) markers and elliptic Fourier analysis of leaflet shape to investigate relationships within and between the seven common dogrose tara in t
This work deals with the problem of interferometric radar phase estimation in the presence of layover. The focus here is on multichannel interferometric synthetic aperture radar (InSAR) systems with a low number of phase centers and nonuniform array geometry. An interpolated array (IA) approach is proposed in order to apply parametric spectral estimation techniques designed for uniform linear arra
Summary: The image of St. Birgitta in the liturgy Since the liturgy was the principal locus for the commemoration of Birgitta in the Middle Ages, the image which liturgical texts conveyed of her is of considerable interest. The essay analyzes the two offices in honour of Birgitta written by Archbishop Birger Gregersson (1367-1383) and Bishop Nils Hermansson (1374-1391,). First, what may be called

A wide scope of application of a novel isothermal sorption microcalorimeter is presented. With the technique, it is possible to simultaneously and independently in one experiment obtain the sorption isotherm of a sample along with the corresponding differential enthalpies of sorption. The method is suited for measurements with water vapor as well as organic vapors and has been tested at temperatur
We studied regeneration distance of rat sciatic nerve, with the sensory pinch reflex test and immunocytochemical staining for neurofilaments, four to 21 days after transsection, repair, and enclosure of the repair site in either a non-absorbable silicone tube or an absorbable polyglycolic acid (PGA) tube. The size of both tube-types was carefully selected so that they did not compress the repaired
This volume of PERLES brings together two studies on bilingual acquisition of Romance languages. Both studies focus in different ways on the age of onset as a factor for development and subsequent mastery of a second language. In the past, the age of onset or the age factor has been studied from a variety of perspectives and often in connection with the Critical Period Hypothesis (CPH) (for a rece
In this paper, we provide a new generalized construction method for highly nonlinear t-resilient functions, F: F-2(n) --> F-2(m). The construction is based on the use of linear error-correcting codes together with highly nonlinear multiple output functions. Given a linear [u, m, t + 1] code we show that it is possible to construct n-variable, m-output, t-resilient functions with very high nonlinea
This is a grounded theory study to identify concepts for describing how adolescents with inflammatory bowel disease (IBD) respond to their parents' concern for them. Ten adolescent boys and seven girls were interviewed. In the analysis four main categories emerged: ambivalence, ability/inability, compliance/resistance and trust/distrust. We found ambivalence to be the most distinctive theme to app
Adult growth hormone deficiency (GHD) is a multifactorial disorder in which pituitary dysfunction associated with pituitary adenomas or their treatment plays a major role. The introduction of recombinant growth hormone (GH) for the treatment of GHD has opened up new treatment avenues but has also raised concerns about possible untoward long-term metabolic effects of GH, such as the potential effec
Popular Abstract in Swedish Uppsatsskrivningen i läroverket har ofta beskrivits på ett negativt sätt: ensidig ämnesgivning, onaturliga skrivsituationer och bristfällig förberedande undervisning. Syftet med denna avhandling är att ta reda på om denna bild av praktiken haft en motsvarighet i teorin eller om det i stället funnits mer ambitiösa och varierade mål för skrivträningen. De material som redThis dissertation is about the goals that existed for Swedish essay writing in grammar schools from the start of the nineteenth century to the 1960s. The point of departure is the contrast between the negative image often painted of this essay writing and the positive picture painted of writing tuition before this period (classical rhetoric) and after it (process-oriented writing with the emphasis
A reduced protein model with five to six atoms per amino acid and five amino acid types is developed and tested on a three-helix-bundle protein, a 46-amino acid fragment from staphylococcal protein A. The model does not rely on the widely used Go approximation, which ignores non-native interactions. We find that the collapse transition is considerably more abrupt for the protein A sequence than fo
Studiecirklar har haft en stor betydelse för arbetarrörelsen, liksom för många andra folkrörelser, under 1900-talet. De var viktiga verktyg för att kunna vara samhällsengagerad och vara med och ta ansvar för det man ansåg vara av ett gemensamt intresse. Att vara med och ta ett ansvar för det gemensamt angelägna och besätta politiska poster runt om i kommunerna krävde kunskap om den kommunala verks
