Drying agents comparison

Drying of carrot chips of 15 mm diameter and 5 mm thickness was conducted on this dryer. Experimental results show that fluidized bed drying with pulse combustor as a source of drying agent characterizes higher drying rate in comparison... 

As for the most common question asked with this technique—Is this "dry" — you should be encouraged to have in your lab a series of flasks which contain a set quantity of solvent and drying agent. The difference with each flask within the series is the percentage of water which allows for a visual comparison of what is and what is not "dry."...

Administration via metered-dose inhaler (MDI) or dry-powder inhaler is at least as effective as nebulization therapy and is usually favored for reasons of cost and convenience. Refer to Table 80-1 in Chap. 80 for a comparison of the available agents. 

When materials other than a lignosulfonate water-reducing agent are used, in conditions where significant drying of concrete can take place, caution must be exercised where straight additions are used and where differential creep rates could be obtained in comparison to adjacent concrete containing no admixtures. 

The immobilization process, however, can be complicated. The immobilization of an enzyme on nylon serves as a point of comparison. The first step is to activate the surface of the nylon by treating it with hydrochloric acid at room temperature for 24 hours. The partially hydrolyzed nylon is then dried in ether and stored in a desiccator overnight. The nylon is then mixed with a coupling agent [l-ethyl-3-(3-dimethyaminopropyl)] and shaken for 1 hour. The enzyme is then added and shaken overnight at 4 C. 

Typical spectra obtained for the probed attached at the network junction are shown in Figs. 2 and 3 The probe in THF possesses the highest ratio for CT/LE. An increased intensity for the LE was measured for the swollen sample. This effect can be explained by different polarity /mobility of the probe One can assume that covalent bonded probes possess another probe mobility than free dissolved probe molecules. Furthermore, the covalent bonded probe molecule that shows a higher polarity in comparison to the siloxane chains is located at the network junction. The attached probe molecule is surrounded mainly by siloxane chains of the network. Addition of polar swelling solvents leads to an increase of the CT-emission and the ratio CT/LE is mainly influenced by the composition of polymer and swelling agent (compare spectra for dried and swollen N1 samples in Fig. 2). Therefore, the covalently bonded probe shows another fluorescence behavior in comparison to the free dissolved probes that can be surrounded also by solvent molecules.
