The ground state properties and absorption spectra of N-benzylideneaniline (NBA) have been studied at the density functional (DFT) and at the time-dependent density functional (TD-DFT) level of the theory. The equilibrium geometries of the E and Z isomers in the ground state and their vibrational frequencies have been computed. Furthermore, the excitation energies of the lowest excited singlet and
The Low-Energy Undulator Test Line (LEUTL) at the Advanced Photon Source, Argonne National Laboratory, is intended to demonstrate the basic operation of a SASE-based free-electron laser. Goals include comparison of experimental results With theoretical predictions and scaling laws, identification of problems relevant to fourth-generation light source construction and operation and the means of add
The Internet contains scientific information in increasing amounts. It is possible to obtain the latest information, and Web services can easily be maintained and updated. We have set up three Internet ser vices an immunodeficiencies. Immunodeficiency-related mutation information is available in immunodeficiency mutation databases (IDbases). Currently 14 registries are distributed, including infor
Genetic engineering has been used to construct fusion proteins with tryptophan containing peptides. The peptides and the fusion proteins have been partitioned in aqueous two-phase systems of poly(ethylene glycol) (PEG)-dextran and Ucon-dextran. The studied model protein was ZZT0, where Z is an engineered domain of domain B of staphylococcal protein A. The specially designed hydrophobic peptides, A
Analyses of their internal stellar kinematics imply that the dwarf spheroidal (dSph) companion galaxies to the Milky Way are among the most dark matter-dominated systems known. Should there be significant dark matter in the form of faint stars in these systems, the stellar luminosity function must be very different from that of a similar metallicity globular cluster, for which there is no evidence
Variability in solute transport properties in the unsaturated zone is of growing concern due to environmental hazards. By combining dye and salt tracers, a detailed description of the solute transport can be made in both time and space. In this paper, qualitative and quantitative effects of preferential flow were investigated in a sandy loam. The experimental site was equipped with 64 TDR probes.
We used video recording of the movement pattern of Protaphorura armata (Collembola) to test whether its avoidance of the odor of dead conspecifics extends to related species. P. armata was repelled by the odor of dead individuals of Onychiurus scotarius and Onychiurus circulans, but not by live individuals. Free palmitic, oleic, and linoleic acids were present in extracts of the three repellent sp
The surface tension of adipic aqueous solution has been measured as a function of temperature (T = 278-313 K) and adipic acid mole fraction (X = 0.000-0.003) using the Wilhelmy plate method. A parameterization fitted to these data is presented. The evaporation rates of binary water-malonic and water-adipic acid droplets have been measured with a TDMA-technique at different temperatures (T = 293-30
Ingmar Brohed var 1978-97 professor i kyrkohistoria vid Lunds universitet, därefter forskningschef vid Svenska kyrkans forskningsråd. Festskriften innehåller 26 artiklar som i huvudsak behandlar svensk och internationell kyrkohistoria från 1700-tal till sent 1900-tal, med perspektiv även från etnologi, historia, kyrkovetenskap, missionsvetenskap, religionssociologi och rättshistoria. De speglar på
Wegener granulomatosis (WG) and microscopic polyangiitis (MP), diseases associated with antineutrophil cytoplasmic antibodies (ANCA), had an extremely poor prognosis before the introduction of cyclophosphamide and corticosteroids for their treatment. However, there is still reduced patient survival, and some studies have documented severe side effects of the immunosuppressants used. This 10-yr fol

Popular Abstract in Swedish Bomärken har använts som ägarbeteckning och signatur i Norden in på 1800-talet, och i vissa reliktområden intill nutid. Bomärkena återfinns t.ex. i mantalslängder, jordaböcker och bouppteckningar, men även inskurna på äldre redskap, husgeråd och annat lösöre. Bomärkena har av somliga forskare ansetts ha utformats slumpvis, enbart med syftet att kunna skilja en bomärkesThe pioneering academic research on Merchant Marks (also known as identity marks, personal marks, ownership marks, identification marks, Hausmarken, Hofmarken, Marques de Propriété, bomärken) was done by professor Homeyer (1870). Since 1870 there has been an ongoing debate among scholars whether Merchant Marks are simply formed by chance and coincidence, as stated by Rehnberg (1938, 1951), Scheffe
Background: The electrophysiological mechanisms underlying atrial fibrillation (AF) are incompletely understood. Experimental studies have shown that remodelling of the atrial myocardium is linked to the occurrence and perpetuation of AF. Interatrial conduction disturbances and also delayed conduction at the posteroparaseptal region have also been reported as potential arrhythmogenic substrates. H
The effects of planktivorous fish on lower trophic levels through predation on zooplankton and nutrient excretion were experimentally separated and their relative importance quantified in a eutrophic humic lake. The experiment was performed in 12 enclosures (3 mi), which initially were identical with respect to all components except fish. At the start of the experiment, caged fish not able to feed
A procedure was developed for the covalent coupling of anti-alpha-fetoprotein antibody (anti-AFP) to a gold surface modified with a self-assembled monolayer (SAM) of thiourea (TU). The performance of the SAM-antibody layer was compared to those of similar layers based on thioctic acid (TA) and 3-mercaptopropionic acid (MPA) by using flow injection capacitive immunosensor system. Covalent coupling
Popular Abstract in Swedish Empiriska studier som fokuserar på subjektivt upplevd hälsa hos patienter i psykiatrin är sällsynta och merparten av de frågeformulär som finns är baserade på en medicinsk grund där objektivt observerbara sjukdomsindikatorer betonas. I studie I och II analyseras och beskrivs uppfattningar av begreppet hälsa hos patienter och sjuksköterskor i psykiatrisk vård med hjälp aEmpirical studies focusing on the subjective experience of health among patients in contact with the mental health services are rare and most questionnaires are based on a medical model that emphasizes objectively observed disease-oriented health indicators. In studies I and II perceptions of the concept of health among patients and nurses in mental health services were explored and described usin
Glial cell line-derived neurotrophic factor (GDNF) exhibits potent effects on survival and function of midbrain dopaminergic (DA) neurons in a variety of models. Although other growth factors expressed in the vicinity of developing DA neurons have been reported to support survival of DA neurons in vitro, to date none of these factors duplicate the potent and selective actions of GDNF in vivo. We r
The steam pressure control loops in the drying section of a paper machine play an important role for the quality of the moisture content control. The steam pressure loops are essential for the effective use of advanced control schemes for the moisture control. From mathematical model building and experiments on industrial paper machines it is found that the dynamics from the steam valves to the st
AIM: To determine the involvement of extracellular signal-regulated kinase 1/2 (ERK1/2) pathway in the expression of endothelin receptor type B (ETB) during culture. METHODS: SB386023, a specific inhibitor for ERK1/2 pathway, was used to define the intracellular signaling pathway for the upregulation of ETB receptors and sarafotoxin 6c (S6c), a selective agonist for ETB receptors, induced contract
