The singlet ground and low-energy excited states of the benzene dimer in D-6h geometry are characterized using second order multireference perturbation theory (CASPT2). The counterpoise-corrected spectroscopic parameters of the benzene excimer are in quantitative agreement with experiment. The same method was used to compute a submanifold of the potential energy hypersurface of the first excited s
Estimates of viability as measured by vital staining with fluorescein diacetate (FDA) were carried out on freshly isolated and partially aged (16-h-old) B. vulgaris and H. vulgare mesophyll protoplasts following irradiation with UV-B. Damage to the photosynthetic system by UV-B was determined by delayed light emission (DLE). In the case of freshly isolated protoplasts Beta was .apprx. 30% more sus
It is shown that in water of finite depth, the surface profile eta of a periodic traveling wave uniquely determines the corresponding flow in the body of the fluid. This holds for rotational flow as long as the vorticity function gamma(psi) satisfies the condition gamma'(psi) max(xis an element ofR) eta(2)(x) < pi(2). This condition is also shown to be sharp.

Popular Abstract in Swedish Fritidsaktiviteter bland personer med reumatoid artrit. Vad predikterar och hur mäter man? Fritidsaktiviteter ansågs redan i antikens Grekland leda till inre tillfredsställelse, mening och värde i livet. De genomfördes enbart för sin egen skull och utan tanke på belöning. I början av 1900-talet kunde fritidsaktiviteter endast genomföras av de personer som inte behövde Leisure Activities in Rheumatoid Arthritis. Associated Factors and Assessment. Leisure activities were considered to give intrinsic pleasure, meaning and value to life already in ancient Greek. It was also performed for its own sake and not by consideration of any external rewards. In the beginning of the 20th century leisure was only possible for wealthy people who could occupy themselves with n
Popular Abstract in Swedish Låg temperatur begränsar i stor utsträckning överlevnad och expansion av vegetation. Under senare år har samverkan mellan låg temperatur och hög instrålning, som leder till försämrad fotosynteseffektivitet, rönt stor uppmärksamhet. I denna avhandling tillämpas nya metoder för att relatera rumsliga variationer i temperatur och instrålning till fotosynteseffektivitet ochLow temperature has a large impact on the survival and distribution of plants. Interactive effects with high irradiance lead to cold-induced photoinhibition, which may impact on the establishment and growth of tree seedlings. In this thesis, novel approaches are applied for relating the spatial variability in low temperature and irradiance to photosynthetic performance and growth of tree seedlings
Aims: A study was undertaken to investigate the relationship between country of birth, time in Sweden, and overweight and obesity. Methods: Approximately 4,000 people aged 20-80 participated in a cross-sectional survey in 1994. The ethnic differences in overweight and obesity were analysed in a multivariate logistic regression analysis adjusting for age and education. The effect of number of years
We obtain an existence theorem for monotone positive solutions of nonlinear second-order ordinary differential equations by using the Schauder-Tikhonov fixed point theorem. The result can also be applied to prove the existence of positive solutions of certain semilinear elliptic equations in R-n (n greater than or equal to 3).
Objectives: To evaluate whether, in patients with carcinoma in situ (CIS) of the urinary bladder, alternating instillation therapy with mitomycin C (MMC) and bacillus Calmette-Guerin (BCG) was more effective and less toxic than conventional BCG monotherapy. Methods: Patients were stratified prospectively for primary, secondary, and concomitant CIS and randomized to one of two regimens. Patients in
Pulmonary function measurements, bronchoalveolar lavage (BAL), and analyses of precipitating antibodies in blood were performed in 12 farmers wtih no symptoms from the airways and 12 farmers who were admitted to the hospital due to acute symptoms of alveolitis (all nonsmokers). In addition, a bronchial methacholine provocation test was performed in the asymptomatic farmers. In 11 of the 12 symptom
A new beam blanking system was installed at the Lund Nuclear Microprobe and employed in proton beam lithography (PBL) for polymer microstructures fabrication. The blanker consists of two parallel plates connected to a high voltage generator. Measurement of the beam blanking time on a sample was performed by means of the standard PIXE system. The beam is blanked and returns to a sample within 200 n
