Apart from tissue-type plasminogen activator (t-PA) and urokinase-type plasminogen activator (u-PA), a third PA appears to occur in human plasma. Its activity is initiated when appropriate triggers of the contact system are added, and the activation depends on the presence of factor XII and prekallikrein in plasma. The activity of this, so...

Within the framework of the Dutch participation in the IEA Annex XIV “Condensation” field experiments have been carried out to study airbome moisture transport in realistic circumstances. The experiments were done in an unoccupied 3-story dwelling in Leidschendam in the Netherlands. Some of the results will be discussed in this paper.

Little is known about the acoustical quality of that part of the Dutch housing stock which was built between 1945 and 1975. One half of the present Dutch housing stock, i.e. 2.6 million units, was built in that period. In this study, acoustical quality was assessed by calculating the indices of airborne and structure-borne sound insulation. It...

In het snelstromende water rond de Oosterscheldedam kunnen allerlei meegevoerde objecten grote schade toebrengen aan de dam. Daarom zoekt Rijkswaterstaat naar mogelijkheden om de zeebodem in de directe omgeving van de dam te inspecteren. Hierbij zou een geavanceerde onderwatercamera uitkomst kunnen bieden. In het High Resolution 3D Imaging...

The past decades have been a time of rapid technological change in health care, but technological change will probably accelerate during the next decade or so. This will bring problems, but it will also present certain opportunities. In particular, the health care system is faced with the need to spend its limited resources more effectively. The...

Four visual search experiments examined the allocation of attention in a multi-item display with a salient stimulus difference. If, irrespective of its relevance to performance, an item with a unique property attracts attention, it can be said that the unique property automatically captures attention. Alternatively, if capturing attention...

Eindelijk lijkt het wat te worden met de zonneboilers. De vraag naar deze systemen trekt duidelijk aan. Als ik goed geïnformeerd ben, produceren de fabrikanten Luigjes Zonne Energie en Zonne Energie Nederland momenteel ruim 100 systemen per maand. Dat is meer dan twee maal de gemiddelde maandproduktie in 1989. Kortom, het produkt slaat aan en de...

A group of 134 school children aged 3-9 y, with signs of conjunctival xerosis, from the rural area of Sakorn Nakhon province of Northeast Thailand were selected for a controlled study on the short-term effect (2 wk) of a single, oral high dose of vitamin A on iron metabolism. After collection of the baseline data, children within villages were...

A new method was developed for rabbit skin organ culture. In a two-compartment model, skin discs were cultured on a Millicell-HA insert unit with a microporous membrane which allows transport of culture medium via the dermis into the epidermis, whereas the epidermal side remains free of direct contact with culture medium. In this relatively...

The history of the components in oral contraceptives and their effects on lipoprotein metaholism is described in this article. Especially the different progestagens are discussed, and their ability to change the lipidprofile either favourably or unfavourably in regard with the effects on cardiovascular disease. Various possible mechanisms are...

1. Administration of endotoxin or fibrinogen degradation products (FDPs) in rats increase nbrinogen synthesis comparable to that found during the acute phase response. 2. An increased fibrinogen synthesis is also found in co-cultures of hepatocytes with peripheral blood mononuclear cells upon administration of endotoxin or FDPs, but not in...

Met het NMP, dat zomer 1989 is verschenen, zal het nooit meer als vroeger zijn. Dat is ons reeds op diverse manieren duidelijk gemaakt door de nieuwe ministersploeg. Ook de keramische industrie zal volop met deze nieuwe ontwikkelingen te maken krijgen, ook al liepen er de laatste jaren reeds de nodige, veelal energiebesparende, projecten. Nu...

Talking about spaceflight is talking about frontiers. Space technology can also be considered as a frontier, as it is well illustrated by the many challenges it imposes on design, materials, technology, accuracy, reliability and management. The TNO Institute of Applied Physics (TPD, Deft, the Netherlands) has contributed to pushing these frontiers.

Endothelial cells play an important role in the regulation of fibrinolysis by the production of several key regulatory proteins. The cytokines tumor necrosis factor (TNF), lymphotoxin, and interleukin-1 (IL-1), but not interleukin-6, increase the production of plasminogen activator inhibitor-1 (PAI-1) by endothelial cells, whereas they have no...
