Elimination of the formation of biofilm in industrial pipes using enzyme cleaning technique
Currently, there is a growing demand in how to eliminate the biofilm formed in industrial pipelines, especially in food, fermentation, and water treatment industry. However, the traditional techniques for CIP (cleaning in place) are usually ineffective, superficial, halfway, and do not clean or sterilize microbes located in the inner layers of the biofilm. A recent strategy for removing the bio...
متن کاملDoes switching from cigarettes to pipes or cigars reduce tobacco smoke exposure?
Cigarette smoking histories, reported depth of inhalation, number of pipe and cigars (PC) smoked, serum thiocyanate (SCN) and expired air carbon monoxide (CO) levels were examined in PC male smokers enrolled in the Multiple Risk Factor Intervention Trial (MRFIT). Serum SCN levels for all PC smokers were higher than for non-smokers and lower than for current cigarette smokers. Levels were relate...
متن کاملFullerene pipes
Single-wall fullerene nanotubes were converted from nearly endless, highly tangled ropes into short, open-ended pipes that behave as individual macromolecules. Raw nanotube material was purified in large batches, and the ropes were cut into 100- to 300-nanometer lengths. The resulting pieces formed a stable colloidal suspension in water with the help of surfactants. These suspensions permit a v...
متن کاملPreviewing Semantic Web Pipes
In this demo we present a first implementation of Semantic Web Pipes, a powerful tool to build RDF-based mashups. Semantic Web pipes are defined in XML and when executed they fetch RDF graphs on the Web, operate on them, and produce an RDF output which is itself accessible via a stable URL. Humans can also use pipes directly thanks to HTML wrapping of the pipe parameters and outputs. The implem...
متن کاملSynchronization of Organ Pipes
We report results on the synchronization of an organ pipe either by a second pipe or by a loudspeaker, positioned side by side. Classical theory suggests oscillation death for the synchronization of two organ pipes. With our measurements we clearly exclude this scenario. Rather, we identify the aeroacoustical coupling by the oscillating wind sheet at the pipe mouth as the source of a self-regul...
