Mesylate
In organosulfur chemistry, a mesylate is any salt or ester of methanesulfonic acid (). In salts, the mesylate is present as the anion. When modifying the international nonproprietary name of a pharmaceutical substance containing the group or anion, the spelling used is sometimes mesilate (as in ''imatinib mesilate'', the mesylate salt of imatinib). Mesylate esters are a group of organic compounds that share a common functional group with the general structure , abbreviated , where R is an organic substituent. Mesylate is considered a leaving group in nucleophilic substitution reactions. Preparation Mesylates are generally prepared by treating an alcohol and methanesulfonyl chloride in the presence of a base, such as triethylamine. Mesyl Related to mesylate is the mesyl (Ms) or methanesulfonyl (CH3SO2) functional group. Methanesulfonyl chloride is often referred to as mesyl chloride. Whereas mesylates are often hydrolytically labile, mesyl groups, when attached to nitroge ...

Morphine Sulfate
Morphine is a strong opiate that is found naturally in opium, a dark brown resin in poppies (''Papaver somniferum''). It is mainly used as a pain medication, and is also commonly used recreationally, or to make other illicit opioids. There are numerous methods used to administer morphine: oral; sublingual; via inhalation; injection into a muscle; by injection under the skin; intravenously; injection into the space around the spinal cord; transdermal; or via rectal suppository. It acts directly on the central nervous system (CNS) to induce analgesia and alter perception and emotional response to pain. Physical and psychological dependence and tolerance may develop with repeated administration. It can be taken for both acute pain and chronic pain and is frequently used for pain from myocardial infarction, kidney stones, and during labor. Its maximum effect is reached after about 20 minutes when administered intravenously and 60 minutes when administered by mouth, wh ...

Mississippi
Mississippi () is a state in the Southeastern region of the United States, bordered to the north by Tennessee; to the east by Alabama; to the south by the Gulf of Mexico; to the southwest by Louisiana; and to the northwest by Arkansas. Mississippi's western boundary is largely defined by the Mississippi River. Mississippi is the 32nd largest and 35th-most populous of the 50 U.S. states and has the lowest per-capita income in the United States. Jackson is both the state's capital and largest city. Greater Jackson is the state's most populous metropolitan area, with a population of 591,978 in 2020. On December 10, 1817, Mississippi became the 20th state admitted to the Union. By 1860, Mississippi was the nation's top cotton-producing state and slaves accounted for 55% of the state population. Mississippi declared its secession from the Union on January 9, 1861, and was one of the seven original Confederate States, which constituted the largest slaveholding states in t ...

MS-13
Mara Salvatrucha, commonly known as MS-13, is an international criminal gang that originated in Los Angeles, California, in the 1970s and 1980s. Originally, the gang was set up to protect Salvadoran immigrants from other gangs in the Los Angeles area. Over time, the gang grew into a more traditional criminal organization. MS-13 is defined by its cruelty, and its rivalry with the 18th Street gang. Many MS-13 members were deported to El Salvador after the end of the Salvadoran Civil War in 1992, or upon being arrested, facilitating the spread of the gang to Central America. The gang is currently active in many parts of the continental United States, Canada, Mexico, and Central America. Most members are Central American, Salvadorans in particular. As an international gang, its history is closely tied to United States–El Salvador relations. In 2018, the gang's US membership of up to 10,000 accounted for less than 1% of the 1.4 million gang members in the United States, and a ...

Missionaries Of La Salette
The Missionaries of Our Lady of La Salette (M.S. - Missionarium Saletiniensis) are a religious congregation of priests and brothers in the Latin Church. They are named after the apparition of Our Lady of La Salette in France. There is also a parallel religious community of sisters called the Missionary Sisters of Our Lady of La Salette. A lay fraternal group of associates also works in cooperation with the vowed religious. The Missionaries are dedicated to making known the message of Our Lady of La Salette, a call to healing of inner brokenness and personal reconciliation with God, especially as found in the first three commandments. The missionaries are popularly known as "the La Salettes." Description Statues from the site of the apparition in the tiny mountain village of La Salette, in the commune of Corps France depict Our Lady addressing two children. The distinctive La Salette crucifix bears a small hammer and pincers on either side of the cross as worn by Our Lady. The ...

Spin Quantum Number
In atomic physics, the spin quantum number is a quantum number (designated ) which describes the intrinsic angular momentum (or spin angular momentum, or simply spin) of an electron or other particle. The phrase was originally used to describe the fourth of a set of quantum numbers (the principal quantum number , the azimuthal quantum number , the magnetic quantum number , and the spin quantum number ), which completely describe the quantum state of an electron in an atom. The name comes from a physical spinning of the electron about an axis, as proposed by Uhlenbeck and Goudsmit. The value of is the component of spin angular momentum parallel to a given direction (the –axis), which can be either +1/2 or –1/2 (in units of the reduced Planck constant). However this simplistic picture was quickly realized to be physically impossible because it would require the electrons to rotate faster than the speed of light. It was therefore replaced by a more abstract quantum-mechanical ...

Mass Spectrometry
Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a ''mass spectrum'', a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures. A mass spectrum is a type of plot of the ion signal as a function of the mass-to-charge ratio. These spectra are used to determine the elemental or isotopic signature of a sample, the masses of particles and of molecules, and to elucidate the chemical identity or structure of molecules and other chemical compounds. In a typical MS procedure, a sample, which may be solid, liquid, or gaseous, is ionized, for example by bombarding it with a beam of electrons. This may cause some of the sample's molecules to break up into positively charged fragments or simply become positively charged without fragmenting. These ions (fragments) are then separated accordin ...

Solar Mass
The solar mass () is a standard unit of mass in astronomy, equal to approximately . It is often used to indicate the masses of other stars, as well as stellar clusters, nebulae, galaxies and black holes. It is approximately equal to the mass of the Sun. This equates to about two nonillion (short scale), two quintillion (long scale) kilograms or 2000 quettagrams: The solar mass is about times the mass of Earth (), or times the mass of Jupiter (). History of measurement The value of the gravitational constant was first derived from measurements that were made by Henry Cavendish in 1798 with a torsion balance. The value he obtained differs by only 1% from the modern value, but was not as precise. The diurnal parallax of the Sun was accurately measured during the transits of Venus in 1761 and 1769, yielding a value of (9  arcseconds, compared to the present value of ). From the value of the diurnal parallax, one can determine the distance to the Sun from the geometry o ...

Master System
The is an 8-bit third-generation home video game console manufactured by Sega. It was originally a remodeled export version of the Sega Mark III, the third iteration of the SG-1000 series of consoles, which was released in Japan in 1985 and featured enhanced graphical capabilities over its predecessors. The Master System launched in North America in 1986, followed by Europe in 1987, and then in Brazil and Korea in 1989. A Japanese version of the Master System was also launched in 1987, which features a few enhancements over the export models (and by proxy the original Mark III): a built-in FM audio chip, a rapid-fire switch, and a dedicated port for the 3D glasses. The Master System II, a cheaper model, was released in 1990 in North America, Australasia and Europe. The original Master System models use both cartridges and a credit card-sized format known as Sega Cards. Accessories for the consoles include a light gun and 3D glasses that work with a range of specially design ...

Millisecond
A millisecond (from '' milli-'' and second; symbol: ms) is a unit of time in the International System of Units (SI) equal to one thousandth (0.001 or 10−3 or 1/1000) of a second and to 1000 microseconds. A unit of 10 milliseconds may be called a centisecond, and one of 100 milliseconds a decisecond, but these names are rarely used. To help compare orders of magnitude of different times, this page lists times between 10−3 seconds and 100 seconds (1 millisecond and one second). ''See also'' times of other orders of magnitude. Examples The Apollo Guidance Computer used metric units internally, with centiseconds used for time calculation and measurement. *1 millisecond (1 ms) – cycle time for frequency 1 kHz; duration of light for typical photo flash strobe; time taken for sound wave to travel about 34 cm; repetition interval of GPS C/A PN code *1 millisecond - time taken for light to travel 204.19 km in a single mode fiber optic cable for a wavelength o ...
