Next Protocol Negotiation
Application-Layer Protocol Negotiation (ALPN) is a Transport Layer Security (TLS) extension that allows the application layer to negotiate which protocol should be performed over a secure connection in a manner that avoids additional round trips and which is independent of the application-layer protocols. It is used to establish HTTP/2 connections without additional round trips (client and server can communicate over two ports previously assigned to HTTPS with HTTP/1.1 and upgrade to use HTTP/2 or continue with HTTP/1.1 without closing the initial connection). Support ALPN is supported by these libraries: * BSAFE Micro Edition Suite since version 5.0 * GnuTLS since version 3.2.0 released in May 2013 * MatrixSSL since version 3.7.1 released in December 2014 * Network Security Services since version 3.15.5 released in April 2014 * OpenSSL since version 1.0.2 released in January 2015 * LibreSSL since version 2.1.3 released in January 2015 * mbed TLS (previously PolarSSL) since ve ...

Non-protein Nitrogen
Nitrogen's effects on agriculture profoundly influence crop growth, soil fertility, and overall agricultural productivity, while also exerting significant impacts on the environment. Nitrogen is an element vital to many environmental processes. Nitrogen plays a vital role in the nitrogen cycle, a complex biogeochemical process that involves the transformation of nitrogen between different chemical forms and its movement through various environmental compartments such as the atmosphere, soil, water, and living organisms. In its natural state, nitrogen exists primarily as a gas (N2) in the atmosphere, making up about 78% of the air we breathe. Nitrogen finds extensive usage across various sectors, primarily in the agriculture industry, and transportation. Its versatility stems from its ability to form numerous compounds, each with unique properties and applications. Impacts on agriculture Nitrogen is a fundamental nutrient in agriculture, playing a crucial role in plant growth and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NPN Transistor
A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor (FET), uses only one kind of charge carrier. A bipolar transistor allows a small current injected at one of its terminals to control a much larger current between the remaining two terminals, making the device capable of amplification or switching. BJTs use two p–n junctions between two semiconductor types, n-type and p-type, which are regions in a single crystal of material. The junctions can be made in several different ways, such as changing the doping of the semiconductor material as it is grown, by depositing metal pellets to form alloy junctions, or by such methods as diffusion of n-type and p-type doping substances into the crystal. The superior predictability and performance of junction transistors quickly displaced the original point-contact transistor. Diffused transi ...

Normal Polish Notation
Polish notation (PN), also known as normal Polish notation (NPN), Łukasiewicz notation, Warsaw notation, Polish prefix notation, Eastern Notation or simply prefix notation, is a mathematical notation in which operators ''precede'' their operands, in contrast to the more common infix notation, in which operators are placed ''between'' operands, as well as reverse Polish notation (RPN), in which operators ''follow'' their operands. It does not need any parentheses as long as each operator has a fixed number of operands. The description "Polish" refers to the nationality of logician Jan Łukasiewicz, who invented Polish notation in 1924. The term ''Polish notation'' is sometimes taken (as the opposite of ''infix notation'') to also include reverse Polish notation. When Polish notation is used as a syntax for mathematical expressions by programming language interpreters, it is readily parsed into abstract syntax trees and can, in fact, define a one-to-one representation for the ...

National Party Of Nigeria
The National Party of Nigeria (NPN) was the dominant political party in Nigeria during the Second Republic (1979–1983). History Formation The party's beginning could be traced to private and sometimes secret meetings among key Northern Nigerian leaders after the proscription of political parties in 1966 by the military regimes of Johnson Aguiyi-Ironsi and General Yakubu Gowon. A few members of the proscribed parties based in the Northern section of Nigeria began to organize to form a northern party to prepare for a return to democracy. The group also approached southern Nigerians about the prospect of a truly national party. A constitutional assembly organized in 1977 to prepare a constitution for a new democratic government, proved to be the best avenue for members of the burgeoning group to meet and discuss plans for their regions and nation. On September 20, 1978, the National Party of Nigeria was formed, composed of members of the constituent assembly and was headed by Mak ...

New Politics Network
The New Politics Network (NPN) was an independent political and campaigning think tank in the United Kingdom, concerned with democratic renewal and popular participation in politics. It was founded as the successor to Democratic Left in 1999, and merged with Charter 88 to form Unlock Democracy in 2007. Origin The NPN was established in December 1999 following the winding up of Democratic Left, the legal successor organisation to the former Communist Party of Great Britain. Its first director was Nina Temple. Democratic Left had briefly become the New Times Network, publishing a magazine, ''New Times'', until the summer of 1999, before it became the NPN. Activities The NPN had around 200 to 250 members. The NPN worked with a wide range of groups and individuals to provide a forum to look at emerging ideas in society. Its stated goal was to provide an independent and innovative debate on the future of politics. With the Joseph Rowntree Reform Trust it funded the tactical voting ...
