For instance, Ca 2+ may interact with two PAs to form a neutral but highly curved complex. The neutralisation of the otherwise repulsive charges of the headgroups and the absence of any steric hindrance enables strong intermolecular interactions between the acyl chains, resulting in PA-rich microdomains.
Pennsylvania (/ ˌpɛnsɪlˈveɪniə / ⓘ PEN-sil-VAY-nee-ə, lit.'Penn's forest country'), officially the Commonwealth of Pennsylvania[ b ] (Pennsylvania Dutch: Pennsylvanie), [ 7 ] is a state spanning the Mid-Atlantic, Northeastern, Appalachian, and Great Lakes regions of the United States.
Differential 0-forms, 1-forms, and 2-forms are special cases of differential forms. For each k , there is a space of differential k -forms, which can be expressed in terms of the coordinates as ∑ i 1 , i 2 … i k = 1 n f i 1 i 2 … i k d x i 1 ∧ d x i 2 ∧ ⋯ ∧ d x i k {\displaystyle \sum _{i_{1},i_{2}\ldots i_{k}=1}^{n}f_{i_{1}i_{2 ...
The lambdas are the eigenvalues of the matrix; they need not be distinct. In linear algebra, a Jordan normal form, also known as a Jordan canonical form, [1][2] is an upper triangular matrix of a particular form called a Jordan matrix representing a linear operator on a finite-dimensional vector space with respect to some basis.
The Payment Application Data Security Standard (PA-DSS) is the global security standard created by the Payment Card Industry Security Standards Council (PCI SSC). [1] PA-DSS was implemented in an effort to provide the definitive data standard for software vendors that develop payment applications. The standard aimed to prevent developed payment ...
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Nylon 66 (loosely written nylon 6-6, nylon 6/6, nylon 6,6, or nylon 6:6) is a type of polyamide or nylon. It, and nylon 6, are the two most common for textile and plastic industries. Nylon 66 is made of two monomers each containing ...
0.224809 lbf. The newton (symbol: N) is the unit of force in the International System of Units (SI). It is defined as , the force which gives a mass of 1 kilogram an acceleration of 1 metre per second squared. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically his second law of motion.
ISO 3166-1 alpha-2 codes are two-letter country codes defined in ISO 3166-1, part of the ISO 3166 standard [1] published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest. They are the most widely used of the country codes published by ISO (the ...
