Due to the low temperature function and the photoinduced hydrophilic effect of the modified TiO2 photocatalytic UF membranes, the photocatalytic reactor can efficiently work without any extra device, fact that leads to low installation and operating costs and provides an energy efficient procedure of cleaning polluted aqueous solutions.
Sixty percent felt no pain during the ART procedure of cleaning and restoring tooth cavities without local anaesthesia, while 99% were satisfied after having received an ART restoration.
The procedure for determination of cleaning additive in diesel fuel described in this paper is based on quantitative isolation from diesel oil of a characteristic fraction containing, depending on origin, aliphatic alcohols with a various length of carbon chain.
It was a curious production, a cut-and-paste compilation of recipes, medical advice, rules of etiquette, procedures for cleaning and essays on natural history and chemistry.
Note, however, that the water-soaked sample had been boiled in nitric acid prior to the water treatment as part of cleaning procedures, indicating that the nonperiodic surface features can be regenerated by aging in water.
In all, four alternative two-step procedures for the determination of cleaning additives in diesel fuel were developed.> The use of mass spectrometry during final determination enables additional quality control of the results through the measurement of ratio of intensities of ions with 70 and 83 m/ z.

A lack of standard procedures for "cleaning" the raw MS data results in several preprocessing steps and different techniques were applied in these steps.
Conventional procedures for cleaning the substrates of III-V semiconductors consist in refluxing the substrate in a sequence of organic solvents such as trichloroethylene, acetone, methanol, and isopropyl alcohol to remove the contamination from heavy hydrocarbons, particles and heavy-atom contaminants [18].
For example, the task may be to choose among several different treatments for future patients, methods of collecting information or procedures for cleaning an operating room.
