Gravity Recovery and Climate Experiment
File:15 Years of Freshwater Trends Seen by GRACE.webm The Gravity Recovery and Climate Experiment (GRACE) was a joint mission of NASA and the German Aerospace Center. Twin satellites took detailed measurements of Earth's gravity field anomalies from its launch in March 2002 to the end of its science mission in October 2017. By measuring gravity anomalies, GRACE showed how mass is distributed around the planet and how it varies over time. Data from the GRACE satellites is an important tool for studying Earth's ocean, geology, and climate. GRACE was a collaborative endeavor involving the Center for Space Research at the University of Texas at Austin, NASA's Jet Propulsion Laboratory, the German Aerospace Center and Germany's National Research Center for Geosciences, Potsdam. The Jet Propulsion Laboratory was responsible for the overall mission management under the NASA ESSP (Earth System Science Pathfinder) program. The principal investigator is Byron Tapley of the University of Texas Center for Space Research, and the co-principal investigator is Christoph Reigber of the GeoForschungsZentrum (GFZ) Potsdam. The two GRACE satellites (GRACE-1 and GRACE-2) were launched from Plesetsk Cosmodrome, Russia, on a Rockot (SS-19 + Breeze upper stage) launch vehicle on 17 March 2002. The spacecraft were launched to an initial altitude of approximately 500 km at a near-polar inclination of 89°. During normal operations, the satellites were separated by 220 km along their orbit track. This system was able to gather global coverage every 30 days. GRACE far exceeded its 5-year design lifespan, operating for 15 years until the decommissioning of GRACE-2 on 27 October 2017. Its successor, GRACE-FO, was successfully launched on 22 May 2018.

Video Toaster
The NewTek Video Toaster is a combination of hardware and software for the editing and production of NTSC standard-definition video. The plug-in expansion card initially worked with the Amiga 2000 computer and provides a number of BNC connectors on the exposed rear edge that provide connectivity to common analog video sources like VHS VCRs. The related software tools support video switching, chroma keying, character generation, animation, and image manipulation. Together, the hardware and software provided, for a few thousand U.S. dollars, a video editing suite that rivaled the output of contemporary (i.e. early 1990s) professional systems costing ten times as much. It allowed small studios to produce high-quality material and resulted in a cottage industry for video production not unlike the success of the Macintosh in the desktop publishing (DTP) market only a few years earlier. The Video Toaster won the Emmy Award for Technical Achievement in 1993. Other parts of the original software package were spun off as stand-alone products, notably LightWave 3D, and achieved success on their own. As the Amiga platform lost market share and Commodore International went bankrupt in 1994 as a result of declining sales, the Video Toaster was moved to the Microsoft Windows platform where it is still available. The company also produces what is essentially a portable pre-packaged version of the Video Toaster along with all the computer hardware needed, as the TriCaster. These became all-digital units in 2014, ending production of the analog Video Toaster line.

Aldosterone
Aldosterone is a steroid hormone that is produced in the adrenal cortex. Its major renal effect is to regulate electrolyte and water homeostasis in the distal tubule, thus maintaining blood pressure and extracellular fluid homeostasis through the activation of mineralocorticoid receptors (MR) in epithelial cells [2]. Aldosterone enters an epithelial cell and binds to the MR. The complex of aldosterone and MR translocates into the nucleus and regulates gene transcription of, among others, the epithelial sodium channel (ENaC) and the signaling proteins and kinases that impact channel and transporter activity, such as serum/glucocorticoid kinases (SGKs).

Diagnosis of Enamel Cracks
Cracked teeth can pose a diagnostic dilemma for a clinician as they can mimic several other conditions. The constant physiological stress along with any pathological strain like trauma or iatrogenic causes can lead to the development of microcracks in the teeth. Constant exposure to immense stress can cause the progression of these often-undiagnosed tooth cracks to cause tooth fractures.

Cardiac IKs (KCNQ1/KCNE1) Channels
The cardiac IKs (KCNQ1/KCNE1) channel is one of the main contributors to the repolarizing currents that regulate the ventricular action potential duration (APD) and thus the QT interval in the electrocardiogram. Mutations in cardiac KCNQ1/KCNE1 channels are the most common cause of congenital defects that cause long QT syndrome (LQTS).

Ceramic-Polymer Composite Membranes
Ceramics and polymers are two main candidate materials for membranes, where the majority has been made of polymeric materials, due to the low cost, easy processing, and tunability in pore configurations. In contrast, ceramic membranes have much better performance, extra-long service life, mechanical robustness, and high thermal and chemical stabilities, and they have also been applied in gas, petrochemical, food-beverage, and pharmaceutical industries, where most of polymeric membranes cannot perform properly.

Diversity of Allanblackia parviflora A. Chev. in Ghana
Allanblackia parviflora A. Chev. is an indigenous tree species that are found in West African rainforest zones. It is an underutilized fruit tree species that have been targeted for improvement as part of efforts to domesticate high-value indigenous multi-purpose trees for fruit and seed production in Africa. Allanblackia has several benefits, such as providing shade, timber, and medicine; however, the production of edible oil from its seeds is the economically most important use. There is evidence that the Allanblackia seed oil, which is used for cooking, the production of margarine and the manufacturing of ointments and soap, is being developed as a new agri-business in Ghana, Nigeria, Cameroon, and Tanzania. Despite the nutritional and socio-economic importance of A. parviflora, it is still at the early stages of its domestication process.

Weights and Measures Acts (UK)
Weights and measures acts are acts of the British Parliament determining the regulation of weights and measures. It also refers to similar royal and parliamentary acts of the Kingdoms of England and Scotland and the medieval Welsh states. The earliest of these were originally untitled but were given descriptive glosses or titles based upon the monarch under whose reign they were promulgated. Several omnibus modern acts are entitled the Weights and Measures Act and are distinguished by the year of their enactment. There have been many laws concerned with weights and measures in the United Kingdom or parts of it over the last 1000 or so years. The acts may catalogue lawful weights and measures, prescribe the mechanism for inspection and enforcement of the use of such weights and measures and may set out circumstances under which they may be amended. Modern legislation may, in addition to specific requirements, set out circumstances under which the incumbent minister may amend the legislation by means of statutory instruments. Prior to the Weights and Measures Act 1985, weights and measures acts were only concerned with trade law where the weight or size of the goods being traded was important. The 1985 act, however, had a broader scope, encompassing all aspects covered by the European Economic Community (EEC) European Commission directive 80/181/EEC. As of 25 April 2012, the current primary legislation in the United Kingdom is the 1985 Act, which was last amended by statutory instrument in 2011. Statutory instruments made under the authority of the Act do not amend the Act per se, but regulate particular areas covered by the Act. The Act is currently enforced by the 200 Trading Standards Offices managed by local authorities around the country. Definitions of units of measurements and the technical equipment relating to weights and measures are provided by the National Measurement Office, an agency of the Department for Business, Innovation and Skills.

Plone is a free and open source content management system (CMS) built on top of the Zope application server. Plone is positioned as an enterprise CMS and is commonly used for intranets and as part of the web presence of large organizations. High-profile public sector users include the U.S. Federal Bureau of Investigation, Brazilian Government, United Nations, City of Bern (Switzerland), New South Wales Government (Australia), and European Environment Agency. Plone's proponents cite its security track record and its accessibility as reasons to choose Plone. Plone has a long tradition of development happening in so-called "sprints", in-person meetings of developers over the course of several days, the first having been held in 2003 and nine taking place in 2014. The largest sprint of the year is the sprint immediately following the annual conference. Certain other sprints are considered strategic so are funded directly by the Plone Foundation, although very few attendees are sponsored directly. The Plone Foundation also holds and enforces all copyrights and trademarks in Plone, and is assisted by legal counsel from the Software Freedom Law Center.
