Use of heparinized versus non-heparinized syringes for measurements of the pleural fluid pH
No full textBackground: Pleural fluid (PF) pH measurement is important for establishing a diagnosis and for guiding clinical management. The current standard practice is to collect PF samples for pH measurement in heparinized syringes at room temperature and to instantaneously process these samples. Objective: The purpose of this study is to investigate the effect of collecting PF in heparinized versus non-heparinized syringes at room temperature on PF pH measurements when processed at various time intervals. Methods: From 50 consecutive thoracenteses, 1 ml of PF was collected anaerobically in each of six 3-ml syringes. Only three syringes were coated with heparin. The samples were processed for PF pH measurements at time 0 (T0) and 1 h (T1) and 2 h (T 2) after collection. All specimens were preserved at room temperature, until the measurements were carried out in duplicates by a calibrated blood gas analyzer. Results: PF pH values were significantly lower with heparinized versus non-heparinized syringes at all time intervals (T 0: pH heparinized = 7.378 ± 0.107 vs. pH non-heparinized = 7.390 ± 0.108; T1: pH heparinized = 7.378 ± 0.115 vs. pH non-heparinized = 7.389 ± 0.111; T2: pH heparinized = 7.367 ± 0.105 vs. pH non-heparinized = 7.389 ± 0.121). In the heparinized syringes, there was a significant decrease in PF pH values at T 2 versus T0 and T1. There were no significant changes in PF pH values over time in the non-heparinized syringes. Conclusions: For serial PF pH measurements, the same type of syringes (either heparinized or non-heparinized) should be consistently used. With heparinized syringes, processing of PF pH measurements should be performed within 1 h after collection. Copyright © 2007 S.

De kosten van een zandsuppletie op het strand van de Kop van Goeree uitgevoerd met behulp van de zogenaamde "Punaise"
No full textIn het 1e deel van het afstudeerverslag van A.H. van Berk (lit. 1) werd de vraag gesteld of een baggersysteem voor het kustonderhoud van de Kop van Goeree met de punaise (fig. 0) in één van de wingebieden A, B of C (fig. 2) kan konkurreren met een systeem met een cutterzuiger in wingebied E. Voor het antwoord op deze vraag zijn de kosten van zowel de uitvoering met de punaise als die met de cutterzuiger bepaald. Deze kosten zijn omgerekend naar de gemiddelde jaarlijkse kosten voor het kustonderhoud en onderling vergeleken. In het tweede deel wordt een handleiding gegeven voor de berekening van de jaarlijkse kosten van het kustonderhoud van de lop van Goeree door zandsuppietie a.b.v. de Punaise.Hydraulic EngineeringCivil Engineering and Geoscience
Determinanten van kennisintensieve onderzoeks- en ontwikkelingssamenwerking
No full textIt is becoming increasingly important for companies to ensure a continuing supply of new knowledge. The development of innovative production processes and marketing strategies as well as better products and services improves the competitive position of firms on the world market. This is of special interest to Dutch firms who have only a small and open home market. The principal research question addressed in this thesis concerns the determinants that influence companies in their choice of whether or not to enter into a knowledge-intensive research and development collaboration. This thesis also looks in detail at the role of publicly financed research institutions such as universities, in the setting of the company innovation process as well as at cooperation among private firms. About 13% of all innovative firms in the Netherlands are engaged in some sort of knowledge-intensive research and development collaboration. Knowledge spillovers are an important reason to reject collaboration as a means of acquiring knowledge because spillovers worsen the appropriability conditions, thus decreasing the economic benefits gained from innovative efforts. In correspondence with the literature we find that a high level of R&D-intensity of the partners involved is a very important prerequisite for entering into knowledge intensive R&D-collaboration. Furthermore an important finding is that the probability of entering into a knowledge-intensive R&D-collaboration increases proportionally to the size of the firm. Most innovative firms choose to be engaged in both private and public types of knowledge intensive R&D-collaboration. From this it can be concluded that public and private types of collaboration are complementary to one another. Knowledge intensive R&D-collaboration is also of strategic importance making the decision whether to introduce either improved or newly-developed products onto the market. Firms engaged in knowledge intensive R&D-collaboration more often choose to introduce new products instead of improved products onto the market.Technology, Policy and Managemen
