Room type list

The Preset list and Room type lists work together to set the overall operation of the effect. Select a Preset first and then a Room type to modify it. As with the XFX Reverb plug-in, tbe Room type sets internal parameters that cannot be adjusted by the user. [Pg.173]

To reverse this process and extract the original media files from an. acd-zip file, from the File menu, select Export Loops. Browse for a location to save the fdes to and click the Save button. It is not a bad idea to create a new folder to store these files in, because there can sometimes be quite a few files in a project. You can select a format for the new media files finm the Save as type list (for example,. wav). Selecting a compressed format such as. mp3 can save room on your disk, but the quality of the loops may suffer. See Chapter 10 on Publishing for more information on file formats, compression, and quality. [Pg.98]

The room temperature conductivity data for a wide variety of ionic liquids are listed in Tables 3.6-3, 3.6-4, and 3.6-5. These tables are organized by the general type of ionic liquid. Table 3.6-3 contains data for imidazolium-based non-haloaluminate alkylimidazolium ionic liquids. Table 3.6-4 data for the haloaluminate ionic liquids, and Table 3.6-5 data for other types of ionic liquids. There are multiple listings for several of the ionic liquids in Tables 3.6-3-3.6-5. These represent measurements by different researchers and have been included to help emphasize the significant vari-... [Pg.111]

Insulin is the one agent that can be used in all forms of DM for blood sugar control. Insulin is the essential treatment for patients with type 1 DM and can overcome insulin resistance in patients with type 2 DM. Insulin is available commercially in various formulations that vary markedly in terms of onset and duration of action and the source from which a product is obtained. Insulins can be divided into four separate classes based on their length of action. Most formulations are available as U-100, indicating a concentration of 100 units/mL. Insulin is typically refrigerated, and most vials are good for 28 days at room temperature. Specific details of insulin products are listed in Table 40-9. [Pg.658]

NMR studies (XH, 13C, 29Si) have shown that the zwitterions 3 and 27-38 also exist in solution (3, 27-29, 31-38, [D6]DMSO 30, CDC13). The NMR data, in context with the results of ab initio studies of 39, can be interpreted in terms of a rapid Berry-type pseudorotation at room temperature, leading to an interconversion of the (A)- and (A)-enantiomers. The 29Si chemical shifts of the zwitterions 3 and 27-38 are listed in Table IV. In most cases, these values are very similar to the isotropic 29Si chemical shifts obtained for the respective crystalline compounds by solid-state 29Si CP/MAS experiments. However, the 29Si chemical shifts observed for 31 (8 -131.9) and 32 (8 -123.0) in solution differ substantially from those determined for... [Pg.233]

Hydroxy-3-methoxy-B-nitrostyrene. A mixture of methylamine hydrochloride (7 g, see precursor section for synthesis) and 10 g of sodium carbonate in 100 ml of methanol is stirred well, filtered, and added to a solution of 219 g of vanillin and 85 ml of nitromethane in 600 ml of ethanol. Keep this solution in the dark at room temp for 71 hours to make the nitrostyrene crystallize out. Filter and wash with cold methanol. Yield 225 grams, nip 166-168°. This and the other two nitriles are reduced by the method listed in the reduction section, JACS, 72, 2781. This reduction can be used to reduce many of the nitro type compounds. [Pg.52]

Two different types of crystals were obtained by cooling crystallization of qulzalofop-ethyl dissolved In ethyl alcohol at room temperature. As shown In Photograph 1, one type consists of plate-llke crystal of 20-50 jum In size and another one Is halrllke crystal of 1-2 pm In short axis size. As shown In Figure 1, different X-ray patterns were obtained for the two crystals. Melting points and heats of fusion were also measured for the two crystal types by DTA and DSC, which are listed In Table I. These results Indicate that the different shapes of the two crystal types are related to differences In crystal lattice. [Pg.262]

Other data are also available (Refs 42 54) Eutectic Formation. TNT forms binary and ternary eutectics with various types of nitro compds and nitrate esters. Many of these are listed by Urbanski (Ref 29) others have been reported more recently (Ref 25). Since the di-nitrotoluenes and the unsymmetrical TNT isomers form such eutectics with 2,4,6-TNT which melt just above room temp, their removal is necessary to prevent exudation from TNT-based expls. One procedure for purifying TNT takes advantage of the fact that the eutectic containing the undesired isomers migrates to the crystal surface (see discussion under Exudation and Purification )... [Pg.754]

Extension of this proline-catalyzed a-amination to the use of aldehydes as starting materials has been described independently by the Jorgensen and List groups [6, 7]. The principle of the reaction and some representative examples are shown in Scheme 7.4. The practicability is high - comparable with that of the analogous reaction with ketones described above. For example, in the presence of 5 mol% L-proline as catalyst propanal reacts with azodicarboxylate 3a at room temperature in dichloromethane with formation of the a-aminated product 5a in 87% yield and with 91% ee [7]. Good yields and high enantioselectivity can be also obtained by use of other types of solvent, e.g. toluene and acetonitrile. The products of type 5 were isolated simply by addition of water, extraction with ether, and subsequent evaporation. [Pg.246]

The 17 rare-earth metals are known to adopt five crystalline forms. At room temperature, nine exist in the hexagonal closest packed structure, four in the double c-axis hep (dhep) structure, two in the cubic closest packed structure and one in each of the body-centered cubic packed and rhombic (Sm-type) structures, as listed in Table 18.1.1. This distribution changes with temperature and pressure as many of the elements go through a number of structural phase transitions. All of the crystal structures, with the exception of bep, are closest packed, which can be defined by the stacking sequence of the layers of close-packed atoms, and are labeled in Fig. 18.1.1. [Pg.683]

With minor exceptions, the samples handled in a radiochemical laboratory are eventually measured with radiation detection instruments. The types of counting equipment in the counting room depend primarily on the scope and purpose of the radioanalytical chemistry laboratory mission. Common detectors of this type are listed in Table 2.1. [Pg.15]

The physical state of the chemical to be analyzed determines the sample preparation method. The majority of the chemicals listed in the Schedules of the CWC are liquids in room temperature. There are also gases or solids in each schedule. Some chemicals are borderline cases, which may be solids in room temperature but melt in the infrared beam, or liquids that are too volatile in the infrared beam. Table 2 summarizes some typical chemicals of each type in the Schedules. [Pg.355]

Table 53 gives a list of a number of cobalt(III)-superoxo complexes which have been isolated as crystalline solids. There is a marked preponderance of complexes of the type [Co(SB)(B)(02)] (SB = SchifF base). The base adducts of simple Co11 porphyrins have low affinities for dioxygen at room temperature and consequently their 1 1 adducts with 02 are not isolable. In contrast, exposure of a solid sample of Collman s picket fence porphyrin system [Co(TpivPP)(iV-Meim)] to 1 atm of dioxygen for 24 h produces [Co(TpivPP)(A(-Meim)(02)] (200).654 The pivalamido pickets in this compound exercise control of solvation about the coordinated dioxygen moiety and the stability is comparable with that of CoMb02,655 where the globin protein environment performs the same function. [Pg.777]

The microcalorimeter. In the past, most immersion microcalorimetry was carried out with two of the four main categories listed at the beginning of Section 3.2.2, namely, isoperibol microcalorimeters, i.e. conventional temperature rise type, and diathermal-conduction microcalorimeters using a form of heat flowmeter. The isoperibol microcalorimeters were the only type used until the 1960s they are easily constructed and are well suited for room temperature operation. Improvements were made in the temperature stability of the surrounding isothermal shield and the sensitivity of the temperature detector. Initially the temperature detector was a single thermocouple, then a multicouple with up to 104 junctions (Laporte, 1950), and... [Pg.131]
