We report preliminary experimental and computational studies of the temporal evolution of the harmonics, generated in xenon, by 50-ps pulses from a Nd: YLF laser, amplified in Nd: glass amplifiers, and focused to produce intensities in the range 1013--5 {\texttimes} 1013 W cm{\textminus}2. Measurements were made of the temporal profiles of the seventh- and ninth-order harmonics using a specially m

High-performance concrete slabs have been field exposed at the Traslovslage marine field station at the Swedish west coast since April 1992 as a part of the Cementa/Euroc sponsored project, "Durability of Marine Concrete Structures." The concrete slabs mounted on a floating pontoon are exposed in three exposure zones: submerged, splash, and upper splash zones. The results after two years of exposu

An ongoing continuous process of automatization of the production lines is used in industry to reduce production costs. Automatization of quality control should be seen as part of a cost reduction process, as well as of quality control of the welding. Mostly the time-consuming and expensive checking procedure of the weld joint is carried out off-line by an experienced welding operator. The need fo

Popular Abstract in Swedish Alpha1-antitrypsin (AAT), som är ett cirkulerande glykoprotein, är den vanligast förekommande serinproteinashämmaren i plasman hos människa. Den ingår i gruppen av akutfasproteiner, och dess halt i plasma kan snabbt öka till koncentrationer överstigande 50 mM vid inflammation, infektion eller malign sjukdom. Då AAT fungerar som en effektiv hämmare av neutrofilelastas ocAlpha1-antitrypsin (AAT), a circulating single-chain glycoprotein is the most abundant serine proteinase inhibitor in human plasma. AAT is an acute phase protein, its levels increase rapidly to concentrations exceeding 50mM in response to inflammation, infection and malignant diseases. Since AAT is a powerful inhibitor of neutrophil elastase and proteinase 3, it is generally assumed that its physi

The mass flow of air through an opening in a well-mixed compartment fire can be calculated with a simple expression. Similar simple models are lacking for the stratified pre-flashover case. Usually an advanced computer model is required to calculate the mass flow through an opening in a pre-flashover compartment fire. However, two equations for the opening mass flow through an opening are presente

Steady state and time-resolved absorption and fluorescence spectroscopy have been used to investigated the energy transfer in photosynthetic purple bacteria. Picosecond light pulses were used in measurements of Rb. sphaeroides WT and a LH1-deleted mutant, demonstrating that the energy trapping into the reaction center in both species occur on the same time-scale, and that the excitation energy is

Jane Eyre is perhaps the best known governess charatcer in nineteenth-century fiction, but as this article shows, Charlotte Brontë's heroine differs radically from the common depiction of governesses at the time. After an outline of the genre characteristics of the governess novel this article offers a close reading of some scenes in Jane Eyre in order to establish to what extent the novel can be

This paper presents three mathematical formulations for designing robust two-layer networks carrying elastic traffic. The formulations differ by the way flow reconfiguration is performed in the case of link failures. An iterative algorithm to solve the problems is given and an extensive numerical study is provided comparing the effectiveness of the three reconfiguration approaches. The formulation

In this paper, heat and mass balances of the intercooler in a 100 kW Proton Exchange Membrane Fuel Cell (PEMFC) system are analyzed by employing a commercial software IPSEpro. The compressor, ambient temperature, the humidification method and the PEMFCs cathode operating temperature were considered as the parameters influencing the heat and mass balances in the intercooler. Parametric studies of t
