Pane Test

At this point, column/variable attributes can be changed. For instance, in the preceding window you see that the Lab Test field defaults to 255 characters wide, which you can easily reduce if desired. If you then click Results in the left pane, you can change where the SAS data set is stored. At this point, click Run and you will see that the import into SAS has taken place in SAS Enterprise Guide. [Pg.67]

It is worth noting that blast capacity of a polycarbonate pane is sensitive to the duration of the blast load. Because of this, the typical short overpressure duration testing of polycarbonate with small close-in charges with frame set-ups that permit a rapid pressure clearing time may give an unconservative estimate of blast capacity in many real world threat scenarios. [Pg.142]

The liquid HED fuel tested, PCU functionalized erro-methylenecyclopro-pane, exhibits large vaporization rates in comparison with existing liquid fuels and some azido-organic compounds. The droplet s combustion had a microexplosive nature due to the large rates of heat released during combustion. [Pg.87]

Miiller has used cyclopropyl clock experiments to test for the possible intermediacy of radical species prior to C-N bond formation (Scheme 17.7). The diphenylcyclopro-pane derivative 3, which fragments at a rate of 2x10 ° s , affords nosylated amine 4 no product from ring opening is observed. Such a result mitigates the viability of a productive stepwise oxidation process, though it is important to note that sulfonamide 4 is formed in only 5% yield. [Pg.382]

The first bombs developed by the US Navy, CBU-55, were used in Vietnam, and tests to perfect an advanced version of the weapons system have continued. The CBU-55B air-to-surface free-fall cluster bombs were developed for helicopter.and siow-speed fixed-wing aircraft delivery to clear helicopter landing zones of mines booby traps. This FAE bomb was designed to disperse a mixt of vaporized fuel (ethylene oxide, propylene oxide, m e thy lacetylene/propa diene/pro pane and others) in a cloud 50 ft in dram and approx 8 ft thick. It has three 100-lb individual canisters 13.6 inches in diam by 21 inches long, each containing ca 72 lbs of fuel. The canisters separate from the dispenser after... [Pg.385]

Before the contaminated soil was processed, the system was tested using surrogate wastes to ensure the emission requirements could be met. Three different series of tests were conducted using various combinations of fuels and wastes. An oxy/pro-pane burner in the PCC was used to incinerate PCB-contaminated soil for the series A and B tests. The only difference between A and B was that propane and oil with 1% PCB, respectively, were used as fuels in the SCC. In series C, the PCC was not operated, while the fuel for the SCC was oil with 42% PCB. [Pg.255]

Other materials being investigated include ferrocene with a bipyridinium salt,234 niobium oxide,235 nickel oxo-hydroxide,236 and cobalt oxohydroxide.237 The last is pale yellow in the reduced state and dark gray in the oxidized state. A typical electrolyte is lithium perchlorate in propylene carbonate. Solid electrolytes, such as a lithium salt (perchlorate, tetrafluoroborate, or triflate), in a polyepoxide238 or in a polyvinyl chloride gel in ethylene carbonate-propylene carbonate,239 lithium iodide in polyvinyl bu-tyral,240 and Naflon H (a polymeric perfluorocarbon-sulfonic acid),241 have also been tested. Some other systems use suspended particles between two panes of glass.242 When the particles are aligned by an electric field, the window becomes transparent. Combination photo-voltaic-electrochromic devices are under study.243... [Pg.453]

Aspirin is known to cause serious reactions in certain patients with asthma (Cooke 1919). The patients can also have rhinorrhea and nasal polyps that may precede the bronchoconstrictor type of intolerance to aspirin for months or years. This triad of symptoms is common in middle-aged women. The aspirin-sensitive patients often show intolerance to other analgesics (Smith 1971). Speer (1958) reported that color additives can precipitate asthma. Aspirin-sensitive patients with asthma also cross-react to tartrazine in 8%-15% of the cases (Chafee and Setti-PANE 1967 Samter and Beers 1967 Hosen 1972 Settipane and Pudupakkam 1975 Delaney 1976) and to various benzoates (Juhlin et al. 1972 Rosenhall and Zetterstrom 1973). Hypersensitivity to food colorants, preservatives, and analgesics was studied in 504 patients with asthma and rhinitis by Rosenhall (1977). Hypersensitivity to at least one of the substances was found in 106 patients. In 33 patients sensitive to tartrazine 42% were intolerant to aspirin and 39% to sodium benzoate. Rosenhall also tested his patients with other azo dyes such as Sunset Yellow and New Coccine as well as the non-azo dyes carmine and patent blue. The method of examination and reproducibility of the results were studied in detail. Dietary treatment was found to be effective in some patients in preventing exacerbations of the disease but on the whole had no influence on the course of the disease or the need for medication. [Pg.645]

Abstract. The syntheses of ( )-l-cyano-2,3-epithiopro-pane (3), ( )-l-cyano 39 -epithiobutane (2), and ( )-l-cyano-i+,5-epithiopentane 4) are described, as are the formation of 3 from allylglucosinolate, and its aglucone, by a Crambe ahyssinioa preparation. Short term tests of 2-4 for mutagenicity and carcinogenicity gave weakly positive results. [Pg.381]

Figure 6.1. Methods for assessing the role of chemical cues in kin recognition in tadpoles and recently metamorphosed frogs. Top depicts standard test aquarium where stimulus tadpoles are placed in end compartments separated with a screen mesh from test animals (in center). Test animals could use both visual and chemical cues emanating from stimulus groups to distinguish between kin and nonkin. To test the role of vision in kin recognition, mesh barriers were replaced with water-tight glass panes that impeded water flow. Middle shows chambers (12.5 x 5.5 x 8 cm) in end compartments in which stimulus tadpoles were placed. The chambers were composed of 3-mm-thick opaque plastic fronts (facing the test animals) and sides. The top, back, and bottom of the chambers were made of 1.5-mm plastic mesh. Several 1.5-mm holes were bored into the sides. These chambers allowed chemical... Figure 6.1.

Rana cascadae tests investigating the role of vision were conducted using the same procedures as described above. However, the plastic mesh forming the end compartments in the test tank was replaced by 4-mm-thick water-tight glass panes (Blaustein O Hara 1982) (see Fig. 6.1). Therefore, in these tests, chemical cues were not transferred between stimulus and test individuals. [Pg.280]

Rhodium(III) complexes of the type RhCl(Cp )(L) (L= P heterocyclic or cydopro-pane-based P ligand) were tested in styrene hydroformylation. A high activity at 40-100°C and 100bar CO H2 = l l, coupled with excellent chemoselectivity toward aldehydes, was observed [41]. [Pg.169]

This test, which is important for automotive leathers in particular, determines the condensation on cooled glass panes of volatiles from the leather or the finish coat It is described in DIN 75201. There are two different methods of measurement (a) the reflectometric method and (b) the gravimetric method. While the gravimetric method indicates the condensed mass, for example after 16 h at 100 °C, the reflectometric method describes the clouding of the cooled glass plate after 3 h at 100 °C. [Pg.300]

The AAL-toxins are hydroxylated, long-chain alkylamines with one esterified pro-pane-1,2,3-tricarboxylic acid moiety. The difference between TA and TB is that TB lacks a hydroxyl group at R4 (Fig. 1). TA and TB are equally active against susceptible tomatoes (56, 58). However, removal of the hydroxyl group at R3, which produces TC, renders the compound much less active (300 ng vs. 10 ng per plant to cause visible symptoms) (28). TD and TE are acetylated forms of TB and TC, respectively. They represent up to 40% of the AAL-toxins produced by fermentation in liquid medium. TD and TE are essentially inactive in phytotoxicity testing and are probably metabolic products from detoxification of the active metabolites (28). [Pg.294]
