In this study we present a new aqueous two-phase system where both polymers are thermoseparating. In this system it is possible to recycle both polymers by temperature induced phase separation, which is an improvement of the aqueous two-phase system previously reported where one of the polymers was thermoseparating and the other polymer was dextran or a starch derivative. The polymers used in this

Serotonin (5-HT) at low concentrations induces an endothelium-dependent relaxation in the rat jugular vein mediated via a 5-HT1-like receptor. The receptor mediating this relaxation was characterized in vitro using agonists and antagonists in segments precontracted with prostaglandin F2 alpha in the presence of the 5-HT2 receptor antagonist ketanserin. The following substances acted as agonists, w

We present the first observation, to our knowledge, of lasing from a levitated, dye droplet. The levitated droplets are created by computer controlled pico-liter dispensing into one of the nodes of a standing ultrasonic wave (100 kHz), where the droplet is trapped. The free hanging droplet forms a high quality optical resonator. Our 750 nL lasing droplets consist of Rhodamine 6G dissolved in ethyl

There are needs to find better and more efficient methods to interpolate precipitation data in space and time. Interpolation of precipitation is explored using a self-organizing map (SOM) in a region with large complexity of precipitation mechanisms (northern Iran). The technique is used both for regionalization and for interpolating monthly precipitation for stations with missing data for 1-, 2-,

Simultaneous SO2 and NOx reduction in flue gas by the dry furnace sorbent injection process was simulated with an entrained-flow reactor. Several ammonium salts as well as urea were tested. Urea was found to give the highest NOx removal efficiency. By using urea-limestone sorbent, >90% SO2 removal and >80% NOx removal were obtained at Ca/S and N/NOx ratios both equal to 2. The DeNO(x) process is m

Let X = (X(t) : t greater than or equal to 0) be a Levy process. In simulation, one often wants to know at what size it is possible to truncate the small jumps while retaining enough accuracy. A useful tool here is the Edgeworth expansion. We provide a third order expansion together with a uniform error bound, assuming third Levy moment is 0. We next discuss approximating X in the finite variation

The macrocyclic lathyrane polyester Euphorbia factor L10 (1a) has been obtained from the seeds of the caper spurge (E. lathyris). The interaction of L10 (1a) and its acetyl derivative (1b) with P-glycoprotein, a multidrug transporter overexpressed in cancer cells and responsible for resistance to chemotherapy, was investigated. The results established lathyrane diterpenoids as a novel chemotype fo

Until recently, the testing of ODE/DAE software has been limited to simple comparisons and benchmarking. The process of developing software from a mathematically specified method is complex: it entails constructing control structures and objectives, selecting iterative methods and termination criteria, choosing norms and many more decisions. Most software constructors have taken a heuristic approa

Popular Abstract in Swedish Den i Malmö verksamme arkitekten Harald Boklund (1868-1924) är avhandlingens huvudperson. Vi får följa hans liv och verksamhet från direktörsvåningen på Konstakademien i Stockholm, över studie- och praktikåren i kejsartidens Berlin och det produktiva kompanjonskapet med August Lindvall i industrialismens Malmö till hans roll som föreningsmänniska, arkitekt, kritiker ochThe major part of this thesis is dedicated to a biography of the Swedish architect Harald Boklund (1868-1924), but also deals with the problematic concepts of cosmopolitism, regionalism and National romanticism i Scanian architecture 1890-1930. Harald Boklund was the son of Johan Boklund, a famous painter and director of the Swedish Academy of Fine Arts in Stockholm. Harald Boklund got his educati
