In this article an operator theoretic interpretation of the generalized Titchmarsh-Weyl coefficient for the Hydrogen atom differential expression is given. As a consequence we obtain a new expansion theorem in terms of singular generalized eigenfunctions.
Ciliate assemblages play a significant role in the microbial food web. The effects of environmental temperature on assemblage composition may be influenced by abiotic factors such as seasonality and disturbance, but the effects of temperature on ciliate assemblages found on different substrata have not been explored. Sandy bottoms and submerged rocks harbour dissimilar ciliate assemblages, and it
We consider the effect of signaling rate (baud rate) on the information rate of single carrier linear transmission systems with Gaussian inputs. Several different communication scenarios are investigated: correlated or uncorrelated symbols, a fixed modulation pulse or a modulation pulse varying with the signaling rate and frequency selective or flat channels. For uncorrelated symbols, we show that
The model for permanent deformation in asphalt concrete (AC) layers used in the Mechanistic-Empirical Pavement Design Guide (MEPDG) was evaluated. Two instrumented flexible pavements were subjected to heavy vehicle simulator testing at three constant temperatures. Permanent deformation modelling was carried out using the MEPDG software v1.003 at the highest accuracy level. The nationally calibrate
Pickering emulsions are emulsions that are stabilized by fine particles. They have been the focus of considerable research in the past decade due to their properties such as high stability with respect to coalescence and Ostwald ripening, as well as due to advances in nanotechnology that allows us to create and characterize nano-scale structures in new ways. This work reviews some of the recent wo
A large gravel pit 30 km north of the Pomeranian ice margin has been investigated. Besides gravel, sand, fines and diamicton, several deposits of organic material are present, some of them showing a typical Eemian Pollen- and macroflora. Previous interpretations assume that the sediments below the Eemian peat belong to the Saalian, and those above the peat to the Weichselian. Sorted sediments in t
We give a simpler proof of the formula, due to J.-L. Lions, for the reproducing kernel of the space of harmonic functions on a domain Omegasubset ofR(n) whose boundary values belong to the Sobolev space H-s(partial derivativeOmega), and also obtain generalizations of this formula when instead of harmonic functions one considers functions annihilated by a given elliptic partial differential operato
By using data from Ecovision on the DJ AIG commodity index made up of commodity futures and the OMX index consisting of Swedish equities I have estimated the correlation between Swedish equities and US commodity futures. The correlation has been examined in a multivariate GARCH setting by using the BEKK model. The purpose has been to examine if commodity futures from a US exchange market can impro
The notion of human rights is built on the fact that they are universal rights and thus applies to everyone without exceptions. Despite this irregular workers are denied their labour rights and their human rights due to the fact that they are living in a country unlawfully. The states use methods as regularizing irregular migrants or enabling tougher sanctions against irregular migration in order
Since the adoption of the Charter of the United Nations the pattern of conflict in the international arena has drastically changed. From largely being a scene for inter-state conflicts, internal conflicts have predominated the post-war era. The few international conflicts that the post-war world has witnessed have originated in civil conflicts. The principle of non-intervention implies the duty fo
In the spring of 2005, the Treaty Establishing a Constitution for Europe (CT) was rejected in French and Dutch referenda. The document, that was to lead the recently expanded European Union (EU) into the future, was instead put on pause for reflection. Why was there such fear and scepticism towards the CT? What was the CT really all about? In this analysis of the CT, I look at the CT from three le
Over the past decades, sustainable production and consumption pattern has been addressed on a global level. Business is a powerful stakeholder in the development of sustainable consumption and production systems as it represents a great proportion of competence, resources and mechanisms (Charter, Gray, Clark and Woolman, 2008). The global approach toward achieving sustainable production and consum
Cancer är en otrevlig sjukdom, som drabbar många människor. Man söker ständigt nya och bättre sätt att bota patienter eller åtminstone lindra sjukdomens framfart. Ett vanligt sätt att behandla cancer är med strålning. Strålningen kan bestå av sk fotoner. Fotoner är samma slags partiklar som t.ex. vanligt ljus. Skillnaden är att de fotoner som används vid strålbehandling av cancer har högre energi "Purpose: The aim of this study was to investigate whether inversely planned intensity modulated radiation therapy (IMRT), using the clinical radiotherapy equipment at hand in our department, renders any advantages regarding dose distribution over conventional radiotherapy for head and neck cancer patients in the ARTSCAN (Accelerated RadioTherapy of Squamous cell Carcinoma in the head And Nec
This study explored time-frequency analysis of surface electrocardiograms in patients with persistent atrial fibrillation for monitoring atrial drug action. Drug loading over 3 days with oral flecainide (n = 13) or amiodarone (n = 17) organized the fibrillatory process expressed by decreased atrial fibrillatory rate, increased rate stability, and decreased exponential decay. Effects were more pron
Tantalum spectra, emitted from a hollow cathode, have been recorded with a Fourier transform spectrometer in the region 2000–5000 Ů The observed hyperfine patterns of Ta II have been analyzed, yielding center-of-gravity wavelengths for 199 lines and hyperfine constants for 38 even and 97 odd levels of Ta II. Improved energy level values have been derived. The laboratory data have been used for a s
Gaboxadol (THIP; 4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol) is an agonist at GABA(A) receptors. THIP concentrations (0.01-50 mM) were applied rapidly to Sf9 cells expressing the human alpha(1)beta(2)gamma(2S) GABA(A) receptors. The EC50 values for the peak current in THIP alone or THIP plus 1 muM diazepam were 154 and 53 muM, respectively. In supersaturating THIP (10-50 mM) the rate of curren
The growing interest in using population balance modeling to describe emulsification processes has spurred an interest in experimentally measuring the breakup frequency. This contribution classifies, compares, and critically reviews the different methods that have been suggested for measuring the breakup frequency, applicable to emulsification devices. Two major approaches can be seen in previous
