Biofiltration of hydrophobic volatile pollutants is intrinsically limited by poor transfer of the pollutants from the gaseous to the liquid biotic phase, where biodegradation occurs. This study was conducted to evaluate the potential of silicone oil for enhancing the transport and subsequent biodegradation of hexane by the fungus Fusarium solani in various bioreactor configurations. Silicone oil w

We study the large-time dynamics of a Markov process whose states are finite directed graphs. The number of the vertices is described by a supercritical branching process, and the edges follow a certain mean-field dynamics determined by the rates of appending and deleting. We find sufficient conditions under which asymptotically a.s. the order of the largest component is proportional to the order

Utsikter - föreläsnngar från Helgonabacken ("Views - Lectures from Helgonabacken" consists of public lectures by teachers at the Department for Comparative Literature, Lund university. Most of the lectures deal with contemporary Swedish literature, but there are also texts on Italian and Danish poetry and American cinema.

Aluminum interacts with negatively charged surfaces in plant roots, causing inhibition of growth and nutrient uptake in plants growing on acid soils. Pectins in the root cell wall form the major cation adsorption surface, with Ca2+ as the main adsorbing cation. Adsorption of Al3+ and Ca2+ to isolated cell wall material of tomato (Lycopersicon esculentum L.) roots was examined at pH 3.00-4.25 and i

Popular Abstract in Swedish En utmaning vid design av interaktiva artefakter är att ta i beräkning den mångfald av digitala ting, system och verktyg människor dagligen sig av ? något som i denna text benämns som en interaktionsekologi. Denna avhandling behandlar tre forskningsteman; för det första hur människor uppfattar och varseblir ljud, och hur vi kan dra nytta av detta när interaktiva ting omA contemporary challenge when designing interactive artifacts is to take into account the wealth of devices, systems, and tools people use every day - here termed an 'interaction ecology'. This thesis addresses three research issues. Firstly, the character of sound perception, and how auditory interaction can be applied to ubiquitous computing. Secondly, how everyday sounds make people aware of su

Several interactions of cytokines with extracellular matrix molecules are mediated by proteoglycans, such as biglycan and decorin. Using surface plasmon resonance, we show for the first time that tumour necrosis factor-alpha (TNF-alpha) binds to both biglycan and decorin with K(d)s of 0.81 microM and 1.23 microM respectively, a binding that was confirmed by Scatchard plots using a solid phase assa

OBJECTIVE: To evaluate a modified uterine artery score based on the pulsatility index and presence or absence of notching in the Doppler velocity waveform recorded from both uterine arteries in relation to the perinatal outcome. METHODS: A retrospective analysis was performed in 741 third-trimester high-risk pregnancies. The uterine artery score was constructed assigning one point to each abnormal

Predatory rule is defined here as a tendency to maximize state revenue, subject to the rulers′ relative bargaining power and transaction costs (Levi, M., 1988, Of Rule and Revenue. Berkeley: Univ. California Press; North, D. C., 1981, Structure and Change in Economic History. New York: Norton). I suggest that the implicit bargaining between Athenian "politicians" and the poor majority generated pr

In the water-oxidizing reactions of photosystem II (PSII), a tyrosine residue plays a key part as an intermediate electron-transfer reactant between the primary donor chlorophylls (the pigment P-680) and the water-oxidizing Mn cluster. The tyrosine is deprotonated upon oxidation, and the coupling between the proton reaction and electron transfer is of great mechanistic importance for the understan

Mediatorless, electrochemically driven, redox transformations of TI (type 1) and T2 copper sites in Trametes hirsuta laccase were studied by cyclic voltarnmetry and spectroclectrochernical redox titrations using bare gold electrode. DET (direct electron transfer) between I he electrode and the enzyme was observed under anaerobic conditions. From analysis of experimental data it is concluded that t

The authors analyze how pro-federative representatives of the European Commission exploit the temporal dimension of identity construction within the EU. The paper shows, through the analysis of speeches and statements of Commission members, how efforts are made to construct a common past and visualize a common future to enhance common identities within the EU. The common past is invoked through re

Late Weichselian lake sediments from a site in southern Sweden, were analysed for stable carbon and oxygen isotopes, as well as plant macrofossils and insect remains. By comparison of independent data sets, general climatic changes were demonstrated. Lithological, chemical and stable isotope data reveal two significant climatic oscillations at ca. 12 200-12 000 and ca. 11 000-10 200 yr BP respecti
