The Electronic Spectrum of Re2Cl82-: A Theoretical Study

One of the prototype compounds for metal-metal multiple bonding, the Re2Cl82- ion, has been studied theoretically using multiconfigurational quantum chemical methods. The molecular structure of the ground state has been determined. It is shown that the effective bond order of the Re-Re bond is close to three, due to the weakness of, in particular, the bond. The electronic spectrum has been calcula

Including recycling potential in energy use into the life-cycle of buildings

Previous life-cycle studies of buildings tended to omit the phases after demolition. If recycling is not included, the potential benefits of recycling are not possible to assess. A parametric study of a one family house is presented which focuses on the potential energy savings by recycling the various building materials after demolition. The results indicate that it can be more important to desig

Impaired opsonization with C3b and phagocytosis of Streptococcus pneumoniae in sera from subjects with defects in the classical complement pathway

Results from studies using mice deficient in specific complement factors and clinical data on patients with an inherited deficiency of the classical complement pathway component C2 suggest that the classical pathway is vital for immunity to Streptococcus pneumoniae. However, the consequences of defects in classical pathway activity for opsonization with C3b and the phagocytosis of different S. pne

Identification of polyenic hydrocarbons from the northern winter moth, Operophtera fagata, and development of a species specific lure for pheromone traps

In order to elucidate the composition of the female sex pheromone of the northern (beech) winter moth, Operophtera fagata Scharf. (Lepidoptera: Geometridae), ovipositor extracts of unmated, calling females were analysed by gas chromatography with simultaneous electroantennographic and flame ionization detection (GC-EAD/FID). Male antennal responses indicated three active components, two of which h

Escalated dose for non-small-cell lung cancer with accelerated hypofractionated three-dimensional conformal radiation therapy

Background and Purpose: To prospectively assess the feasibility and efficacy of a hypofractionated accelerated radiotherapy regimen (72 Gy in 24 daily fractions, 3Gy per fraction) in patients (pts) with non-resectable non-small-cell lung cancer (NSCLC). Material and Methods: We included 25 Ins with a histologically or cytologically proven NSCLC, with KPS greater than or equal to 70 and less than o

Muscular rest and gap frequency as EMG measures of physical exposure: the impact of work tasks and individual related factors

Owing to an orderly recruitment of motor units, low threshold type I fibres are presumed to be vulnerable in contractions of long duration. To study load on these fibres muscular rest was registered as the time fraction of electromyographic (EMG) activity below a threshold. Moreover, the frequency of periods with muscular rest, EMG gaps, was derived, since a low gap frequency has been shown to be

Expression of Helix pomatia Lectin Binding Glycoproteins in Women with Breast Cancer in Relationship to Their Mood Group Phenotypes

Aberrant glycosylation occurs in essentially all types of human cancers. A difference in glycopattern of proteins will result in a change of function of the proteins. The lectin from Helix pomatia (HPA) recognizes N-acetylgalactosaminylated glycoproteins and very consistent results over the increased binding of HPA in tissue sections are associated with metastasis progression and poor patient prog

Children with asthma. Few adjustment problems are related to high perceived parental capacity and family cohesion

A cross-sectional investigation of 59 Swedish 7-9-year-olds with asthma and their parents was undertaken to study family factors of importance to the children's psychological adjustment. Children scored the I Think I Am questionnaire, a measure of global self-worth, parents the Child Behaviour Checklist (CBCL). Parents' report of family cohesion was assessed with the Family Climate questionnaire,

Healthy skin of many animal species harbors papillomaviruses which are closely related to their human counterparts.

Papillomaviruses associated with clinical symptoms have been found in many vertebrate species. In this study, we have used an L1 gene consensus PCR test designed to detect a broad spectrum of human skin papillomaviruses to analyze swab samples from healthy skin of 111 animals belonging to 19 vertebrate species. In eight of the species, papillomavirus DNA was found with the following prevalences: c

Determinants of local ant (Hymenoptera: Formicidae) species richness and activity density across Europe

1. Species richness is influenced by local habitat features and large-scale climatic gradients. Usually, both influences are studied in isolation because of the divergent spatial scales at which they occur. Here, we compared the influence of large-scale climate and local habitat type on European ants using a continent-wide, standardised sampling programme. 2. We investigated species richness and a

Hepatic and extrahepatic malignancies in primary sclerosing cholangitis

Background/Aims: To assess the risk of hepatic and extrahepatic malignancies in a large cohort of Swedish primary sclerosing cholangitis (PSC) patients compared with that of the general Swedish population. Methods: The study cohort comprised 604 PSC patients identified between 1970 and 1998. Follow-up was provided through linkages to the Swedish Cancer and Death registries. Cumulative incidence of

Fast kriging of large data sets with Gaussian Markov random fields

Abstract in Undeterminedpatial data sets are analysed in many scientific disciplines. Kriging, i.e. minimum mean squared error linear prediction, is probably the most widely used method of spatial prediction. Computation time and memory requirement can be an obstacle for kriging for data sets with many observations. Calculations are accelerated and memory requirements decreased by using a Gaussian

Phase Behavior in Aqueous Two-Phase Systems Containing

The phase behavior of the three-component PEO-PPO-PEO/dextradwater system has been studied. Pluronic L64, P105, and F68 were used, and they are members of a family of triblock copolymers with the structure PEO-PPO-PEO, where PEO is poly(ethy1ene oxide) and PPO poly- (propylene oxide). Moreover, these triblock copolymers tend to self-aggregate in aqueous solution at increasing temperature. The phas
