Was progressively increased

The mass of naphthalene injected was progressively increased from 1.1 mg to 19.1 mg. The results obtained are shown in Figure 8, as curves relating the retention distance of the front and rear of each peak against sample mass. [Pg.429]

A second line of evidence Is provided by an experiment In which the degree of crosslinking of photopolymerlzed specimens was progressively Increased by exposure to Y-rays. The expectation was that crosslinking should reduce plastic deformation by preventing macromolecules from slipping past one another. [Pg.432]

It was reported that the 0-0 distance in the peroxide is 1.458 A, and that this value agreed well with values of 1.464, 1.463, and 1.469 A in the triclinic diaquo, difluoro, and nitrilotriacetic acid (NTA) complexes, respectively. The Ti-Operoxo distance (1.833 A) was compared with the values 1.834 and 1.856 A, 1.846 and 1.861 A, and 1.889 and 1.892 A, respectively, and the Ti-Owater apical distances of 2.018 A with the Ti-0 (F) values of 2.022 and 2.055 A in the triclinic diaquo, 1.853 and 1.887 A in the difluoro and 1.819 and 2.065 A in the NTA complexes. It was concluded that while the 0-0 bond distance of the peroxo group was practically the same in all the structures, there was a small but significant variation in the Ti-Operoxo and apical distances. There was progressive increase in the Ti-Operoxo bond lengths down the respective series, and a corresponding decrease in the apical bond lengths. ... [Pg.6]

For the DMA trace in Fig. 35—typical for almost all reported literature data—it is obvious that both ac- and -relaxations are more pronounced for the /1-nucleated material than for its non-nucleated counterpart suggesting both its amorphous and crystalline phases to be more mobile. Varga showed the progressive increase of the maximum of the loss factor, tan 8, as Kfj was progressively increased from 0 to 75% [137]. This improved damping obviously favors fracture resistance [48,72,77,190]. Detailed correlations between the intensity of the relaxations and the impact strength in -nucleated PP would be beyond the scope of this review they are published elsewhere [111, 191]. [Pg.86]

A 46-year-old man with prosthetic cardiac valves took acenocoumarol and later started to take stavudine, lamivudine, and ritonavir 600 mg bd. His INR fell markedly. Although the dose of acenocoumarol was progressively increased to three times the original dose, it was impossible to achieve the previous INR, and ritonavir was withdrawn. [Pg.2161]

For further study, three samples which did not exhibit pressure decay after compression to 13 dynes/cm were selected. The stability limit for films of these materials was established by incremental compression, holding the monolayer at constant area for up to 15 min as surface pressure was progressively increased. In the second part of Table I, a typical experiment is detailed. By this procedure, these monolayers were each stable to a surface pressure of 16-18 dynes/cm. There was no hysteresis in compression-expansion cycles (at 2-10% of the total film area per minute) as long as this surface pressure was not exceeded. On the other hand, in a continuous compression experiment (at such rates), surface pressures of 27—32 dynes/cm could be developed before obvious evidence of film collapse (e.g., an increase in compressibility, or bending over of the 7r-A curve). Figure 1 shows the ir-A curves for these three samples, and characterization data are given in Table II. [Pg.349]

Oxygen was thus admitted at a given temperature, and for each temperature, the oxygen content was progressively increased in the 0.2 - 10 vol. % range. [Pg.593]

In this type of tests the combined effect of the temperature and the hydration on the behaviour of the clay was investigated. The tests were performed at 25 and 80 C in the oedometer shown in Figure 2, and the procedure to manufacture the samples was the same described in section 3.1. After the initial heating under a low vertical stress, the samples were saturated with distilled water under a vertical load of 1 MPa. Afterwards, the vertical load was progressively increased up to 20 MPa. [Pg.307]

Samples of the three calcined monoliths, after completing the campaign of DeNOx tests and being unloaded from the reactor, were reduced into fine powders and subject to TPD analysis (temperature programmed desorption) in a microreactor. Under a flow of He, the temperature of the catalyst bed was progressively increased up to 800°C and a mass spectrometer registered the nature and concentration of desorbed species. Sulfate... [Pg.155]

An isolated report descrihes a woman with schizoaflective disorder successfully treated for 3 years with haloperidol and carhamazepine who was given sertraline 50 mg daily for depression. When she failed to respond, the sertraline dosage was progressively increased to 300 mg daily but her sertraline plasma levels remained low (about 17 to 25% of those predicted). Another patient on carbamazepine similarly failed to respond to the addition of sertraline and had low sertraline levels. In an analysis of plasma sertraline levels the concentration to daily dose ratio of sertraline was significantly lower in patients who had taken sertraline with carbamazepine compared with those who had taken sertraline without carbamazepine, suggesting that carbamazepine lowered sertraline levels. [Pg.535]

A 35-year-old man, started on lithium earbonate 250 mg four times a day, had a serum-lithium level of 0.5 mmol/L by the following morning. When the dosage fiequency was progressively increased to five, and later six times a day, his serum-lithium levels did not exceed 0.6 mmol/L because, unknown to his doctor, he was also taking sodium bicarbonate. [Pg.1128]

Han et al. synthesized a SPEsUU from PCL, L-lysine ethyl ester diisocyanate (LDl), and L-lysine ethyl ester (LEE) as chain extender [92], The mechanical properties of the electrospun tubular scaffolds increased with solution concentration, as the fiber diameter was progressively increased. The values of suture-retention strength were higher than those of native blood vessels, whereas the burst pressure strength was slightly lower. No compliance data were reported. The scaffolds displayed no cytotoxicity against L-929 mouse fibroblasts or HUVECs, and in vitro cell attachment proved to be successful. [Pg.463]

Begot et al. (Begot, 2010) also succeeded but only after 40 min of self-start at -9°C with a PEMFC system made of a 52 cells stack with 156 cm of active area and with graphite compound bipolar plates (3.5 kW). The FC stack was dried at room temperature prior to cold start and the current was progressively increased as the cell voltages remain stable around 0.76 V. [Pg.260]

Figure 28.3 reports, for instance, the results of propane oxidative dehydrogenation tests over the VMgO-washcoated monolith. Product distributions are plotted as a function of propane conversion, which was progressively increased by increasing the temperature of an external heating furnace. [Pg.956]

Dr Peterlongo wishes more details, were made during the zero energy phases of reactor commissioning at different coolant temperatures. They confirmed our predictions, based on NPSH data supplied by the pump makers, Hayward Tyler Ltd. The method used was to record the pressure rise across the pump as the flow was progressively increased until a point was reached at which a fall-off of pressure was observed. This point was established by comparison with a previously established non-cavlta-ting pump characteristic. The fall-off of pressure with flow beyond the cavitation limit was fairly rapid and the tests were not continued far beyond this point. [Pg.173]
