Methanesulfonyl chloride is mainly used to give methanesulfonates by its reaction with alcohols in the presence of a non-nucleophilic base. [8] In contrast to the formation of toluenesulfonates from alcohols and p-toluenesulfonyl chloride in the presence of pyridine, the formation of methanesulfonates is believed to proceed via a mechanism wherein methanesulfonyl chloride first undergoes an ...

Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
MscL was first discovered on the surface of giant Escherichia coli spheroplasts using patch-clamp technique. [3] Subsequently, the Escherichia coli MscL (Ec-MscL) gene was cloned in 1994. [4] Following the cloning of MscL, the crystal structure of Mycobacterium tuberculosis MscL (Tb-MscL), was obtained in its closed conformation. [5]
The wider the pipe, the greater the suppression. Thus, other factors being equal, wide pipes are poor in harmonics, and narrow pipes are rich in harmonics. The scale of a pipe refers to its width compared to its length, and an organ builder will refer to a flute as a wide-scaled stop, and a string-toned gamba as a narrow-scaled stop.
Application of a ramp of negative pressure to a patch excised from an E. coli giant spheroplast gave a small conductance (MscS; ~1 nS in 400 mM salt) with a sustained open state, and a large conductance (MscL; ~3 nS) with faster kinetics, activated at higher pressure. MscS was reported to exhibit a weak anionic preference and a voltage ...

The exception to this is when a storm sewer operates at full capacity, and then can become pipe flow. Energy in pipe flow is expressed as head and is defined by the Bernoulli equation . In order to conceptualize head along the course of flow within a pipe, diagrams often contain a hydraulic grade line (HGL).
