The spectroscopic properties of a molecule is strongly dependent on interactions with the surrounding environment. We have used time dependent density functional theory (TDDFT) and a multilevel perturbation model to study the transition energies, polarizability, and dipole moments of a bacteriochlorophyll in an electric field. The perturbation Hamiltonian was constructed as to give an electric fie
Thirty-five strains of Pasteurella multocida from humans and animals were tested for susceptibility to five cephalosporins by a broth dilution method. Cefcanel showed high activity against all isolates (MIC and MBC, less than or equal to 0.64 micrograms/ml). The corresponding figure for cefaclor and cefuroxime was 2.56 micrograms/ml. Cefadroxil and cephalexin were the least active compounds tested
Popular Abstract in Swedish POPULÄRVETENSKAPLIG SAMMANFATTNING För varje person som har problem med alkohol berör's i genomsnitt minst ytterligare en person. Under de senaste två decennierna har medvetenheten och kunskapen om de anhöriga's situation och hur de känslomässigt kan påverka's av ett långvarigt alkoholproblem ökat. Den stres's alkoholproblemet skapar påverkar den anhörige's samspel mRandomized studies of various support programs for spouses and children of alcoholics are few in the international literature. This thesis comprises two randomized controlled studies of intervention programs for two family groups: spouses living with an alcoholics partner (paper I and II) and university students who have grown up with at least one parents with alcohol problems (paper III and IV).
PURPOSE: This study assessed whether there is a dilating diathesis in peripheral arteries of patients with abdominal aortic aneurysms (AAAs). METHODS: The anteroposterior diameters of the common femoral artery (CFA) and popliteal artery (PA) were measured in 183 consecutive patients with an AAA (158 men, 25 women; age range, 57-78 years) before elective surgery on the AAA and compared with that of
This paper describes a method for online supervision of control loops that automatically detects oscillations in the loops. The paper describes the method, its implementation in a Honeywell TDC3000 system, and experiences obtained from its use in the mill AssiDomän Frövi.
The quality of the waste sampling procedure and chemical analysis was evaluated in a research program on characterization of organic waste obtained after disc screening of source-separated organic household waste. The sampling procedures focused on a truckload of waste and involved several steps of subsampling including shredding, mixing, blending, high-speed-blending, drying and milling prior to
Goran Sonnevi's poetry represents a vast network of associations to other texts and other works of art. Consequently, this poetry often initiates a conversation on the present with partners from different times, Places and arts. "Burge, Oja; 1989" is an interesting example of such an intermedial conversation, set in the middle of a dramatic period of our time, the year 1989. The central theme is t
A combined solid-phase extraction (SPE)-supercritical fluid extraction (SFE) procedure was developed for the analysis of polychlorinated biphenyls (PCBs) in wastewater. The importance of cleaning and drying the filters and SPE-disks prior to eluting PCBs with SFE was studied, leading to improved recoveries for all congeners investigated. The average PCB recovery of the final procedure, at a concen

The adsorption of the dicarboxylates o-phthalate, maleate, fumarate, malonate, and oxalate (representing ligands with the general composition -O2C-C-n-CO2; n = 0, 1, or 2) on gibbsite were studied by means of quantitative batch adsorption experiments and attenuated total reflectance Fourier. transform infrared (ATR-FTIR) spectroscopy. The interpretations of ATR-FTIR spectra were aided by compariso
Popular Abstract in Swedish Avhandlingen kretsar kring centralbankens möjligheter att kontrollera inflationstakten. Under senare tid har mycket forskning ägnats åt att analysera och utvärdera de institutionella förutsättningarna för centralbanker, såväl avseende graden av oberoende som vilka mål penningpolitiken bör inriktas mot; exempelvis direkta inflationsmål versus användandet av indirekta målAfter an introductory chapter, the hypothesis is made in chapter two: that central bank power to control the rate of inflation rests on the bank’s ability to achieve a role as a focal point for inflation. Inflation is a measure of changes in the general price level, the price level is an index of individual prices, and to predict future price levels is thus to predict future prices on individual i
In recent years, the formation of thin, well-ordered but complex surface oxides on late transition metals has been discovered. The driving force for this line of research has been the strong incentive to increase the partial pressure of oxygen from ultra-high vacuum to conditions more relevant for heterogeneous catalysis. Here we review the present status of the research field. Compared to oxygen
In his 1958 thesis Stability and Error Bounds, Germund Dahlquist introduced the logarithmic norm in order to derive error bounds in initial value problems, using differential inequalities that distinguished between forward and reverse time integration. Originally defined for matrices, the logarithmic norm can be extended to bounded linear operators, but the extensions to nonlinear maps and unbound
Objective: The prognostic influence of neuroendocrine (NE) differentiation in prostate cancer patients is not yet properly established. In a series of primary hormone-naive prostate cancers from a patient population that underwent radical prostatectomy, we wanted to determine the relationship between NE phenotype expression and Gleason sum, disease stage, and serum PSA concentration. Methods: Ch
