Test Fuel

Most previous laboratory-scale deposit simulator studies have considered mainly fuel or lubricant composition and properties, with no consideration of possible effects of NOx, which may affect initiation of the deposit formation process and the overall rate at which deposition occurs. In this study a laboratory-scale deposit simulator was developed which produced thin deposit films by spraying gasoline on to a heated aluminium sleeve to investigate the effects of temperature, NO2 and possible gasoline blending components, on deposit formation. The amount of deposit collected is indicative of the deposit-forming tendency of the test fuel. The deposit film composition was analysed using Fourier transform infrared (FTIR) spectroscopy. The results of the experiments indicate that deposit formation is indeed sensitive to NO2, in addition to the effects of temperature and the molecular structure of the hydrocarbons. Thus the effect of NOx in deposit-related studies is important and should not be ignored. The FTIR analyses showed that when using NO2 the deposits are of a very similar structure to those produced in a real engine test. The analyses also gave some insight into the role of NO2 in the deposit formation mechanism.

SummaryInfusion of desamino-d-arginine vasopressin (DDAVP) results in an increase in plasma plasminogen activator activity. Whether this increase results in the generation of plasmin in vivo has never been established.A novel sensitive radioimmunoassay (RIA) for the measurement of the complex between plasmin and its main inhibitor α2 antiplasmin (PAP complex) was developed using monoclonal antibodies preferentially reacting with complexed and inactivated α2-antiplasmin and monoclonal antibodies against plasmin. The assay was validated in healthy volunteers and in patients with an activated fibrinolytic system.Infusion of DDAVP in a randomized placebo controlled crossover study resulted in all volunteers in a 6.6-fold increase in PAP complex, which was maximal between 15 and 30 min after the start of the infusion. Hereafter, plasma levels of PAP complex decreased with an apparent half-life of disappearance of about 120 min. Infusion of DDAVP did not induce generation of thrombin, as measured by plasma levels of prothrombin fragment F1+2 and thrombin-antithrombin III (TAT) complex.We conclude that the increase in plasminogen activator activity upon the infusion of DDAVP results in the in vivo generation of plasmin, in the absence of coagulation activation. Studying the DDAVP induced increase in PAP complex of patients with thromboembolic disease and a defective plasminogen activator response upon DDAVP may provide more insight into the role of the fibrinolytic system in the pathogenesis of thrombosis.

Insight Into

This essay examines a polemic between two Baudelaire critics of the 1930s, Jean Cassou and Benjamin Fondane, which centered on the relationship of poetry to progressive politics and metaphysics. I argue that a return to Baudelaire's poetry can yield insight into what seems like an impasse in Cassou and Fondane. Baudelaire provides the possibility of realigning metaphysics and politics so that poetry has the potential to become the space in which we can begin to think the two of them together, as opposed to seeing them in unresolvable tension. Or rather, the tension that Baudelaire animates between the two allows us a new way of thinking about the role of esthetics in moments of political crisis. We can in some ways see Baudelaire as responding, avant la lettre, to two of his early twentieth-century readers who correctly perceived his work as the space that breathes a new urgency into the questions of how modern poetry relates to the world from which it springs and in which it intervenes.
