A 80V bipolar lead-acid battery was constructed and tested using Hybrid Electric Vehicle (HEV) drive cycles. Drive cycles with a peak power of 6.7kW, equal to 1/5 of the total power profile required for the HEV studied, were run succesfully. Model calculations showed that the constructed 80V module, which is at the moment 2.5 times more heavy...

Membrane gas absorption for carbon dioxide production from flue gases is discussed with special reference to the economics of the supply of carbon dioxide to greenhouses in the Netherlands. Novel absorption liquids have been introduced which show as excellent performance in terms of system stability and mass transfer when used in combination...

It has now been recognised that services play a vital role in advanced industrial economies. In most European Union (EU) member states service activities now provide around two-thirds of all jobs and Gross Domestic Product (GDP) and even higher proportion of total firms. More particularly services have provided the bulk of new jobs in the...

The C I, Na I D, and Hα lines of the post-AGB binary HR 4049 have been studied. Na I D variability results from a photospheric absorption component ([Na/H]=-1.6 ± 0.2) which follows the velocity of the primary and a stationary, nonphotospheric component. An emission component is attributed to the circumbinary disc, and an absorption component to...

Roundwood as a construction material is becoming more and more interesting to users. Using this wood in construction will increase the value of the material and may open new opportunities for construction design. In order to use roundwood for this application, suitable connectors and/or joints have to be developed, but before all, the strength...

A fast and accurate ray model is developed for sound propagation in a downward refracting atmosphere. The model employs a new approach to the classification and computation of ray paths and caustic curves. The approach is valid for a large set of smooth sound-speed profiles, including realistic, nonlinear profiles such as the logarithmic profile...

An approximate representation for the current along a perfectly conducting straight thin wire is presented. The current is approximated in terms of pulsed waves that travel along the wire with the velocity of the exterior medium. At the ends of the wire, these pulses are partially reflected, with a constant reflection coefficient and delay time....

A disturbed hypothalamus-pituitary-adrenal gland axis and alterations at the immune system level have been observed in patients with chronic fatigue syndrome (CFS). Glucocorticoids are known to modulate T cell responses; therefore, purified CD4 T cells from CFS patients were studied to determine whether they have an altered sensitivity to...

The endogenous ABA contents of dormant and nondormant barley grains were determined following application of different compounds to break dormancy. The chemicals used for breaking of dormancy in intact dormant grains were weak and strong acids, alcohols,. hydrogen peroxide, cyanide, nitrate, salicylic acid, gibberellic acid and fusicoccin. The...

ln recent years PHARUS, a phased array synthetic aperture radar airborne instrument, has been developed by a Dutch team of institutes. Now that the experimental value for PHARUS has been demonstrated, it is important to investigate the commercial potential of this instrument in an end-to-end system for operational services. ln the presented...

In the past several laboratories have conducted human object tests in order to derive biofidelity performance requirements for crash dummmies and computer models. Both human volunteer and human cadaver tests have been conducted. Particularly noteworthy are the human volunteer tests conducted at the Naval Biodynamics Laboratory (NBDL) in New...

The production of active dried starter cultures can be influenced at several levels in the production process. In this paper the following process factors are discussed: osmotic stress during growth and cell density prior to drying. Contradicting results are reported in the literature on the influence of osmotic stress during growth on the...

The stress protein α B-crystallin was recently identified as a component of central nervous system myelin that is strongly immunogenic to human T cells. Stress-induced αB-crystallin that accumulates in the central nervous system is phosphorylated and recent evidence indicates that both rodent and human T cells can discriminate between...

In dit artikel wordt aan de hand van gegevens uit recente onderzoeken nagegaan in welke mate werkdruk als probleem wordt onderkend, wat de omvang van dit probleem is en wat er aan gedaan wordt. In Nederland is sinds 1977 een stijging waar te nemen van het percentage werknemers dat zegt in 'hoog tempo' te moeten werken. Nederland is binnen Europa...
