The moth Macroglossum stellatarum can learn the color and sometimes the odor of a rewarding food source. We present data from 20 different experiments with different combinations of blue and yellow artificial flowers and the two odors, honeysuckle and lavender. The experiments show that learning about the odors depends on the color used. By training on different color—odor combinations and testing
Radio-controlled model planes are useful when carrying out photography, especially from low altitudes, and meteorological soundings (air temperatures in boundary layers). Soundings were carried out with a system which stored the measured data on board the plane pending evaluation after the flight. The payload of the plane was a camera and equipment for measuring temperature and air pressure (altit
Inbreeding increases the level of homozygosity, which in turn might depress fitness. In addition, individuals having the same inbreeding coefficient (e.g. siblings) vary in homozygosity. The potential fitness effects of variation in homozygosity that is unrelated to the inbreeding coefficient have seldom been examined. Here, we present evidence from wild birds that genetic variation at five micros
During the last 10-15 years, the implantable cardioverter-defibrillator (ICD) has become an important mode of treatment for patients suffering from grave ventricular arrhythmias, but ICD implantation involves psychosocial adjustments for both patients and relatives. The aim of this pilot study was to design a plan of education and to follow a selected group of patients with interviews, observation
Widespread lesions of forebrain cholinergic or noradrenergic projections by intraventricular administration of 192 IgG-saporin or 6-hydroxydopamine, respectively, accelerate kindling epileptogenesis. Here we demonstrate both quantitative and qualitative differences between the two lesions in their effects on hippocampal kindling in rats. Epileptogenesis was significantly faster after noradrenergic
The SAFE dynamic model was applied to a ''clean rain'' roof experiment performed within the EXMAN project. In the experiment ambient throughfall was removed and replaced with artificial ''clean throughfall''. Input of S, N and H to the forest ecosystem was reduced by 75-100%. The results of the modelling show, that the time scales of model predictions and experiments are the same. The change in ba
Diphenylphosphinoethylene methyl sulfide, Ph2PCH2CH2SMe, reacts with [Os3(CO)11(NCMe)] yielding [Os3(CO)11(Ph2PCH2CH2SMe)]. Treatment of [Os3(CO)10(NCMe)2] with 1 equiv of the P,S ligand initially yields the cluster 1,2-[Os3(CO)10(-Ph2PCH2CH2SMe)], in which the phosphine and the thioether moieties coordinate to different metal atoms of the metal triangle; addition of two or more equivalents of the
The degradation of hydroxyethyl cellulose (HEC) using sodium persulfate (NaPS) as free radical generator was studied at 60, 70 and 80 degrees C with different NaPS/HEC ratios. During the degradation reaction samples were withdrawn at regular intervals. The amount of persulfate remaining was analyzed by titration and the evolution of the HEC molecular weight distribution and viscosity was followed
The radiation and total efficiencies, the amount of gas radiation from vapour and carbon dioxide and contribution from convective heat transfer for different operating conditions have been measured and modelled in an industrial gas heated IR dryer. Instrumentation to facilitate the measurement of the spectral distribution of the radiation heat fluxes in industrial infrared equipment has been devel
A number of anion-exchange adsorbents were constructed, employing nonporous silica fibers, and examined with the aim of describing factors that influence desorption and recovery of plasmid DNA (pDNA). The fibers were provided with ligands via adsorption of the polymeric amines poly(ethyleneimine) or chitosan, or via graft-polymerization of primary, tertiary, or quaternary amine monomers to vinyl-s
Transfer of N-15 between interacting mycelia of a wood-decomposing fungus (Hypholoma fasciculare) and an ectomycorrhizal fungus (Tomentellopsis submollis) was studied in a mature beech (Fagus sylvatica) forest. The amount of N-15 transferred from the wood decomposer to the ectomycorrhizal fungus was compared to the amount of N-15 released from the wood-decomposing mycelia into the soil solution as

In Sweden, only a few empirical studies of couple therapy have been performed. This is the hitherto most comprehensive assessment of clinical treatment. Effectiveness of treatment is reported and compared with non-clinical ratings. Initially the couples displayed marital distress, many psychiatric symptoms, dyadic interactions characterized by high criticism and a low sense of coherence. In Sweden
The effects of ruthenium red, an inorganic dye with known capsaicin antagonist properties, was investigated in the rabbit eye. At a dose of 0.24 nmol ruthenium red inhibited the inflammatory effects of capsaicin (1 or 8 nmol). Unexpectedly, when the dye was injected in doses ranging from 0.24 to 7.4 nmol, it caused an inflammatory response with constriction of the pupil (miosis) and a breakdown of
