Parameterization of Thermal Properties of Aging Secondary Organic Aerosol Produced by Photo-Oxidation of Selected Terpene Mixtures

Formation and evolution of secondary organic aerosols (SOA) from biogenic VOCs influences the Earth's radiative balance. We have examined the photo-oxidation and aging of boreal terpene mixtures in the SAPHIR simulation chamber. Changes in thermal properties and chemical composition, deduced from mass spectrometric measurements, were providing information on the aging of biogenic SOA produced unde

Epidemiology of mesenteric vascular disease: clinical implications.

The overall incidence rate of acute mesenteric ischemia between 1970 and 1982, diagnosed at either autopsy or operation, in the population of Malmö, Sweden was estimated at 12.9/100,000 person-years. Autopsy rate was 87%. Acute superior mesenteric artery (SMA) occlusion (embolus/thrombus ratio = 1.4), mesenteric venous thrombosis (MVT), and nonocclusive mesenteric ischemia (NOMI) were found in app

Cross-Sectional Area and Strength Differences of Fiberwire, Prolene, and Ticron Sutures.

PURPOSE: Flexor tendons should be repaired with suture material strong enough to permit early motion and small enough for the resulting knot to allow unimpeded tendon glide and healing. This study sought to define differences in cross-sectional area and knotted tensile strength among Fiberwire, Prolene, and Ticron sutures. METHODS: Five strands, each of 3-0 and 4-0 Prolene, Ticron, and Fiberwire s

Prevalence of exclusively and concomitant pelvic fractures at magnetic resonance imaging of suspect and occult hip fractures.

Pelvic fractures may occur together with hip fractures as a result of low energy trauma. It is unclear whether they do require special attention. There are conflicting results in the literature about the prevalence of both concomitant hip and pelvic fractures as well as exclusive pelvic fractures. It has been reported that hip fractures and obturator ring fractures are mutually exclusive. To retro

Reduced Order Models for On-Line Parameter Identification of the Activated Sludge Process

A reduced order dynamic model for an activated sludge process performing carbonaceous removal, nitrification, and denitrification is proposed. Based on directly measurable real time data - by methods available today - all model parameters are identified on-line. A simplified extended Kalman filter is used for the actual identification. Verification of the results is based on computer simulations o

A one-dimensional computational model for the interaction of phase-transformations and plasticity

In this work, we model the basic mechanisms of the interaction between phase-transformations and plasticity within a one-dimensional constitutive framework. Efficient algorithms are presented, facilitating to solve the underlying evolution equations with high numerical stability at low numerical costs. Furthermore, a family of functions covering physically reasonable classes for the inheritance of

Sick leave of spouses to cancer patients before and after diagnosis.

Abstract Background. The impact of cancer on spouses of cancer patients may be considerable in many aspects. Our objective was to evaluate sick leave in spouses of cancer patients before and after the diagnosis. Material and methods. Using Swedish population-based registries, we studied sick leave of spouses to patients with newly diagnosed colon, rectal, lung, prostate, or breast cancer. We ident

Microstructural changes caused by carbonation of cement mortar

The change of specific surface area and pore size distribution due to carbonation of an ordinary Portland cement mortar is investigated. The adsorption of water vapor on noncarbonated and well-carbonated cement mortar is measured in order to evaluate the difference in specific surface area for the two samples using the BET theory. From the measured desorption the pore size distribution is calculat

Att äga rum. Litterär turism som resor i heterotopierna

In this article the phenomenon of literary tourism is approached through the Foucauldian concept heterotopias. A heterotopia is a a bridge between worlds, a physical place or a representation of a place, where transgression is possible. This can be applied to literary tourism, and in this specific case the literary walk, where the tourist goes between his och her own experiences of reading, into t
