Search for B-s(0)-(B-s(0))over-bar oscillations and a measurement of B-d(0)-(B-d(0))over-bar oscillations using events with an inclusively reconstructed vertex

Neutral B meson oscillations in the B-s(0) - , and B-d(0) - systems were studied using a sample of about 4.0 million hadronic Z decays recorded by the DELPHI detector between 1992 and 2000. Events with a high transverse momentum lepton were removed and a sample of 770 k events with an inclusively reconstructed vertex was selected. The mass difference between the two physical states in the B-d(0)

Modeling of Hindered Diffusion in Gels

Popular Abstract in Swedish Ordet diffusion kommer från det latinska ordet diffu´sio som betyder spridning. Diffusion förekommer nästan överallt, även om man inte alltid kan se det. Exempelvis består all den luft som vi andas in av en mängd molekyler som diffunderar fram och tillbaka. Eller så kan det vara vattenmolekyler som diffunderar in till plåten på bilen och gör så att den rostar, eller varHindered diffusion occurs in the most different processes, as has been described in this thesis. It is very important to have an understanding of the influence of hindered diffusion on the mass transfer rate, especially when competing rate processes are acting simultaneously. Using mathematical modeling and simulation makes it possible to predict the effects of hindered diffusion. The systems that

An introduction to BioArray software environment

BioArray Software Environment (BASE) is a web-based software package for storing, searching, and analyzing locally generated microarray data and information surrounding microarray production. The workflow begins in sample management and, optionally, microtiter plate tracking and ends in visualization and analysis of entire experiments. The relative ease with which new analysis plug-ins can be adde

Intraplacental choriocarcinoma: a report of two cases

Two examples of intraplacental choriocarcinoma are described. Both were small and had arisen in otherwise normal third trimester placentas. The covering mantle of many of the villi adjacent to the choriocarcinomas was formed, either focally or wholly, of neoplastic trophoblastic tissue: it is only at this stage of the development of a choriocarcinoma that villous structures are present, and a stud

Visualization of ergonomic guidelines - A comparison of two computer aided systems to support vehicle design

Guidelines are used in information and quality management systems to ensure high quality by supporting design, production and communication processes. These guidelines can be presented as a conventional system on an intranet suitable for printouts, visualized as a traditional text-based report with a list of headings accompanied by tables and pictures or presented as paper documents in manuals or

Intracellular mechanisms in rd1 mouse retinal degeneration

Popular Abstract in Swedish Ärftlig blindhet orsakas oftast av sjukdomar där näthinnans fotoreceptorer, som ombesörjer omvandlingen av ljus till elektriska impulser, degenererar. Det anses att denna celldödsprocess styrs av ett antal olika mekanismer och projektets mål är att försöka identifiera och karaktärisera dessa mekanismer. Retinitis Pigmentosa (RP) är en ärftlig sjukdom där en genetisk defRetinitis pigmentosa (RP) is an inherited disorder and the leading cause of visual impairment in the working age population. It is caused by a number of different genetic mutations, all of which cause the rod photoreceptors to degenerate. As the rods become few in numbers, the cones will also begin to die, resulting in total blindness. Since the genetic defects leading to RP are numerous, it would

Fast on-column protein digestion with subsequent peptide mapping using tandem mass spectrometry with information dependent acquisition

A platform for rapid on-line protein digestion of protein mixtures for direct infusion to a mass spectrometer is presented. A mixture of protein A, staphylococcal enterotoxin B and cytochrome c was used as a model mixture injected on a gel filtration column and a trypsin reactor which were connected in series to a micro liquid chromatography (mu LC) system. The peptides in the column eluate were a

Bose-Einstein condensation of indirect excitons in coupled quantum wells

We study the ground-state properties of a quasi-two-dimensional Bose Einstein condensate of indirect excitons, which are confined in an anisotropic harmonic potential. Incorporating the interactions, we calculate the order parameter variationally. The difficulties in the detection of a Bose-Einstein condensate are also discussed, along with possible ways which would overcome them.

Comparison of different flowability tests for powders for inhalation

A series of placebo powders for inhalation was characterized regarding bulk density and powder flowability using different techniques. The powders were of the ordered mixture type and were prepared by mixing a pharmaceutical carrier grade of lactose with different fractions of intermediate sized and fine (i.e., micronized) lactose. A modified Hausner Ratio was obtained by measurement of the poured

A Swedish non-word repetition test for preschool children

A Swedish non-word repetition test for preschool children was constructed with the aim of measuring short-term phonological memory, which has been shown to correlate with language development and language proficiency. Normative data based on results for 200 children four to six years of age are presented. An item analysis of the original 30-item test resulted in a shortened 24 non-word version fou

Direct ESR Evidence for SH2 Type Reaction of a Methyl Radical with Methylsilane and Methylgermane in a Low Temperature Solid: a Deuterium Labelling Study

The first ESR spectroscopic evidence of a bimolecular homolytic substitution (SH2) reaction in a 77 K solid phase was presented, where radicals were substituted for the CH3 group of methylsilane and methylgermane (CH3XD3, X = Si, Ge). The radicals were generated by in situ UV-photolysis of CD3I in the solid CH3XD3 in an ESR cavity at 77 K. Using the selectively deuterium labeled compounds, it was

Amino acid substitutions in the N-terminal segment of cystatin C create selective inhibitors of lysosomal cysteine proteinases

We used site-directed mutagenesis to alter the specificity of human cystatin C, an inhibitor with a broad reactivity against cysteine proteinases. Nine cystatin C variants containing amino acid substitutions in the N-terminal (L9W, V10W, V10F and V10R) and/or the C-terminal (W106G) enzyme-binding regions were designed and produced in Escherichia coli. It was discovered that the inhibition profile

Hushållskunder på energimarknaden

Man kan identifiera fem stora kundsegment på energimarknaden nämligen hushåll i småhuslägenheter, hushåll i flerbostadshusen lägenheter, fastighetsägare till flerbostadshus, unga hushåll samt medelålders och äldre hushåll. Jämfört med energiföretagens andra kundsegment inom exempelvis industri, handel, service eller myndigheter är hushållssegmenten oorganiserade. De innehåller många hushåll med be
