This study combines AHP and GIS to provide decision makers with a model to ensure optimal site location(s) for fire stations selected.The roles of AHP and GIS in determining optimal locations are explained, criteria for site selection are outlined, and case study results for finding the optimal fire station locations in Istanbul, Turkey are include
Micromotors are extensively applied Cyclist Accessories - Triathlon - Mens Triathlon in various fields, including cell separation, drug delivery and environmental protection.Micromotors with high speed and good biocompatibility are highly desirable.Bubble-driven micromotors, propelled by the recoil effect of bubbles ejection, show good performance
Single-molecule fluorescence provides high resolution spatial distributions of ribosomes and RNA polymerase (RNAP) in live, rapidly growing E.coli.Ribosomes are more strongly segregated from the nucleoids (chromosomal DNA) than previous widefield fluorescence studies suggested.While most transcription may be co-translational, the evidence indicates
