Real-time Kinematic Positioning
Real-time kinematic positioning (RTK) is the application of surveying to correct for common errors in current satellite navigation (GNSS) systems. It uses measurements of the phase of the signal's carrier wave in addition to the information content of the signal and relies on a single reference station or interpolated virtual station to provide real-time corrections, providing up to centimetre-level accuracy (see DGPS). With reference to GPS in particular, the system is commonly referred to as carrier-phase enhancement, or CPGPS. It has applications in land surveying, hydrographic surveying, and in unmanned aerial vehicle navigation. Background The distance between a satellite navigation receiver and a satellite can be calculated from the time it takes for a signal to travel from the satellite to the receiver. To calculate the delay, the receiver must align a pseudorandom binary sequence contained in the signal to an internally generated pseudorandom binary sequence. Since ...

Receptor Tyrosine Kinase
Receptor tyrosine kinases (RTKs) are the high-affinity cell surface receptors for many polypeptide growth factors, cytokines, and hormones. Of the 90 unique tyrosine kinase genes identified in the human genome, 58 encode receptor tyrosine kinase proteins. Receptor tyrosine kinases have been shown not only to be key regulators of normal cellular processes but also to have a critical role in the development and progression of many types of cancer. Mutations in receptor tyrosine kinases lead to activation of a series of signalling cascades which have numerous effects on protein expression. The receptors are generally activated by dimerization and substrate presentation. Receptor tyrosine kinases are part of the larger family of protein tyrosine kinases, encompassing the receptor tyrosine kinase proteins which contain a transmembrane domain, as well as the non-receptor tyrosine kinases which do not possess transmembrane domains. History The first RTKs to be discovered were the ...

Radio Television Of Kosovo
The Radio Television of Kosovo (; ; RTK) is the public service broadcaster in Kosovo. It was founded after the Kosovo War, replacing the equipment and property of the RTS branch in Pristina. RTK operates two radio services, offering a diverse range of news, music, and entertainment programs. Additionally, it runs four 24-hour television channels, broadcasting a variety of content including news, sports, culture, movies, and documentaries. RTK’s services are available on terrestrial and satellite networks, ensuring wide accessibility across Kosovo and to the diaspora. As a public service broadcaster, RTK is funded through a combination of public funding, advertising revenue, and donations. The RTK replaced the Radio Television of Pristina (; ) which was originally founded in 1974 until its end in 1990. History Radio Television of Pristina (1974-1992) In 1945, Radio Pristina (Albanian: ''Radio Prishtina'') began broadcasting out of Prizren following the Second World War. Th ...

Rentech
Rentech, Inc. (stands for Renewable Energy Technology ) was a Los Angeles, Californiabased company that owned and operated wood fiber processing and nitrogen fertilizer manufacturing businesses. It provided wood chipping and wood pellet services through a subsidiary Fulghum Fibres, Inc. and sold nitrogen fertilizer through Rentech Nitrogen Partners, L.P. In addition, Rentech owned the intellectual property for a number of energy technologies, such as Rentech–SilvaGas Gasification Process and Fischer–Tropsch process based Rentech Process. Energy technologies Rentech was initially formed in 1981 by Charles Benham and Mark Bohn to develop and commercialize synthetic fuel technologies. In 1991, it incensed its Rentech Process to the Fuel Resources Development Company (Fuelco) to produce diesel fuel from landfill gas at the Synhytech facility in Pueblo, Colorado. Rentech obtained ownership of the facility in 1993. This project failed and was closed at the same year due to l ...

Right To Know
Right to know is a human right enshrined in law in several countries. UNESCO defines it as the right for people to "participate in an informed way in decisions that affect them, while also holding governments and others accountable". It pursues universal access to information as essential foundation of inclusive knowledge societies. It is often defined in the context of the right for people to know about their potential exposure to environmental conditions or substances that may cause illness or injury, but it can also refer more generally to freedom of information or informed consent. Australia Right to know regarding environmental hazard information is protected by Australian law, which is described at Department of Sustainability, Environment, Water, Population and Communities. Right to know regarding workplace hazard information is protected by Australian law, which is described at Safe Work Australia and at the Hazardous Substances Information System. Canada Right t ...
