Facilitization agitation

The checkers employed 75 mL DMSO rather than 50 mL to facilitate slurry agitation with nearly identical results. Benzylamine was purchased through Aldrich Chemical Company, Inc. and used without further purification. 

The fact that P.Y.127 recrystallizes only very slightly facilitates its dispersion in modern agitated ball mills. The pigment is easy to disperse and its heat stability parallels that of P.Y.13. Its fastness to clear lacquer coatings and to sterilization are excellent, which is why the pigment is suitable for metal deco printing. 

The requirements for solid-phase synthesis are diverse. The support must be insoluble, in the form of beads of sufficient size to allow quick removal of solvent by filtration, and stable to agitation and inert to all the chemistry and solvents employed. For continuous-flow systems, the beads also must be noncompressible. Reactions with functional groups on beads imply reaction on the inside of the beads as well as on the surface. Thus, it is imperative that there be easy diffusion of reagents inside the swollen beads and that the reaction sites be accessible. Accessibility is facilitated by a polymer matrix that is not dense and not highly functionalized. A matrix of defined constitution allows for better control of the chemistry. Easier reaction is favored by a spacer that separates the matrix from the reaction sites. Coupling requires an environment of intermediate polarity such as that provided by dichloromethane or dimethylformamide benzene is unsuitable as solvent. 

The use of slowly rotating rakes is beneficial in large thickeners to direct the underflow to the central outlet at the bottom of the tank. At the same time the slow motion of the rakes tends to give a gentle agitation to the sediment which facilitates its consolidation and water removal. The height requirement of the rakes must be added to that needed for the thickening zone to achieve the desired underflow concentration. 

At-line LIF methods are either based on intrinsic detection or extrinsic approaches. The former often involves static measurements which are prone to photobleaching and thermal effects. These problems can often be addressed by optimizing the excitation source output (i.e., optical power and pulse rate) or by sample agitation. Flow injection analysis or other autonomous sample prepreparation schemes are possible to facilitate various at-line extrinsic methods such as various selective fluoroimmunoassays. ... 

The emission of a helium nucleus in the final stage regenerates the initial carbon-12. The latter thus plays the role of a catalyst. The overall result is the fusion of four protons into a helium nucleus. At high temperatures, this cycle dominates over the proton-proton chain. Indeed thermal agitation facilitates penetration of the relatively high electrical barrier between proton and carbon nucleus. Whatever hydrogen fusion mechanism is prevalent, the star s mass determines the rate at which it consumes its nuclear fuel, and hence also its lifetime. The higher its mass, the more quickly it bums. 

Mixing. Mixing can be accomplished by mechanical recirculation, agitation or by controlled gas flow methods. The practice is desired to facilitate on intimate contact between methane forming bacteria and their substrate and to prevent the formation of surface scum in the digester. 

The simplest method of sampling is to put the sample into a sealed vial and heat it as shown in Figure 11.23. The sample, either in solution or slurried with a relatively involatile solvent with little potential for interference, e.g. water, is put into a sealed vial fitted with a rubber septum and heated and agitated until equilibrium is achieved. Then a fixed volume of head space, e.g. 1 ml is withdrawn. The sample is then injected into a GC in the usual way. If capillary column GC is used a split injection has to be used to facilitate sample injection a flow of 10 1 out of the split vent would ensure that a 1 ml sample could be injected in about 5 s with the flow through the column being 1 ml/min. Several points are important to note ... 

Dutch Pride Product s EcoPlus technology was developed as a dispersant for spiUed oil floating on water, in soil, or on machinery. EcoPlus is designed to facilitate breakup of the oil fihn into small droplets through agitation and brushing. According to the vendor, this reduces both toxic and environmental effects of the oil and the increased surface area makes the oil more accessible... 

All further procedures are performed at room temperature and samples are handled in mesh-buckets with a 12-well plate unless otherwise specified see Fig. 2). Wear gloves when moving mesh-buckets manually. All the wash steps are conducted with a defined incubation time indicated by moving up and down the buckets softly but occasionally to ensure thorough mixing. To facilitate the transfer of individual embryos, use a pipette fitted with a 200 pi or a 1,000 pi tip that was cut to make a wide opening, but avoid excessive agitation. 

Kinsella (13, 14) summarized present thinking on foam formation of protein solutions. When an aqueous suspension of protein ingredient (for example, flour, concentrate, or isolate) is agitated by whipping or aeration processes, it will encapsulate air into droplets or bubbles that are surrounded by a liquid film. The film consists of denatured protein that lowers the interfacial tension between air and water, facilitating deformation of the liquid and expansion against its surface tension. 

Place the prepared flask on a horizontal shaker at a low speed for gentle agitation at ambient conditions to extract the process solvents from the propellant. The MEK will swell the propellant to facilitate removal of process solvents. 

A typical bourbon fermentation continues for 72 hours at a fermentation temperature within the 31—35°C range. Many fermentation vessels are equipped with agitation and/or cooling coils that facilitate temperature control. Significant increases in yeast numbers occur during the first 30 hours of fermentation. Over 75% of the carbohydrate is consumed and converted to ethanol. Within 48 hours, 95% or more of the ethanol production is complete.
