Vanadium Redox Flow Battery
Large-scale energy storage systems (ESS) are nowadays growing in popularity due to the increase in energy production by renewable energy sources, which in general have a random intermittent nature. Currently, several redox flow batteries have been presented as an alternative of the classical ESS; the scalability, design flexibility and long life cycle of the vanadium redox flow battery (VRFB) have made it to stand out. In a VRFB cell, which consists of two electrodes and an ion exchange membrane, the electrolyte flows through the electrodes where the electrochemical reactions take place. Computational Fluid Dynamics (CFD) simulations are a very powerful tool to develop feasible numerical models to enhance the performance and lifetime of VRFBs.

Lusterware
Lusterware or Lustreware (respectively the US and all other English spellings) is a type of pottery or porcelain with a metallic glaze that gives the effect of iridescence. It is produced by metallic oxides in an overglaze finish, which is given a second firing at a lower temperature in a "muffle kiln", or a reduction kiln, excluding oxygen. The discovery of this technique can be traced back to the 7th century A.D. when Islam emerged in the city of Mecca. Lusterware was first created for the royal courts and the technique of lusterware on ceramic was developed originally in Iraq. Some pieces were signed by their makers, this acted as an indication of the admiration towards each craftsman. Trading in the Middle East was very popular. Abbasid lusterware was very common in trade within the Islamic world; other popular trade items were textiles and various materials for building and crafting (ivory, wood, etc.). The Abbasid period served as an era of discovery especially in relation to the production of luster. The city of Baghdad, Iran and surrounding cities were located on the Silk Road which was the hub of trading during this period. There was a movement of goods generated between Iraq and China which triggered artistic emulations both ends, as well as some transfers of technologies, notably in the realm of ceramics. Lusterware traveled along the trade routes; the production of ceramic lusterware was seen in Egypt and Syria during later centuries.

Hybrid Convolutional Neural Network–Bidirectional Long Short-Term Memory
Recognition of lying is a more complex cognitive process than truth-telling because of the presence of involuntary cognitive cues that are useful to lie recognition. Researchers have proposed different approaches in the literature to solve the problem of lie recognition from either handcrafted and/or automatic lie features during court trials and police interrogations.

Fountain (Duchamp)
Fountain is a readymade sculpture produced by Marcel Duchamp in 1917: a porcelain urinal signed "R.Mutt". In April 1917, an ordinary piece of plumbing chosen by Duchamp was rotated 90 degrees on its axis and submitted for an exhibition of the Society of Independent Artists, the first annual exhibition by the Society to be staged at The Grand Central Palace in New York. Fountain was not rejected by the committee but it was removed from the show area, since Society rules stated that all works would be accepted from artists who paid the fee. Following that removal, Fountain was photographed at Alfred Stieglitz's studio, and the photo published in The Blind Man. The original has been lost. The work is regarded by art historians and theorists of the avant-garde as a major landmark in 20th-century art. Sixteen replicas were commissioned by Duchamp in the 1950s and 1960s and made to his approval. Some scholars have suggested that the original work was by a female artist rather than Duchamp, but this is a minority view among historians.

Bloom's Taxonomy
Bloom's taxonomy is a set of three hierarchical models used to classify educational learning objectives into levels of complexity and specificity. The three lists cover the learning objectives in cognitive, affective and sensory domains. The cognitive domain list has been the primary focus of most traditional education and is frequently used to structure curriculum learning objectives, assessments and activities. The models were named after Benjamin Bloom, who chaired the committee of educators that devised the taxonomy. He also edited the first volume of the standard text, Taxonomy of Educational Objectives: The Classification of Educational Goals.

Bump Fire
Bump fire is the act of using the recoil of a semi-automatic firearm to fire shots in rapid succession, which simulates the rate of fire of a fully automatic firearm. Bump fire gunstocks are of varying legality in the United States. The Department of Justice announced a plan on March 23, 2018 to classify bump stocks as "machine guns" and effectively ban them nationwide under existing federal law. If the rule becomes final, existing bump stocks would be required to be destroyed or surrendered by both manufacturers and individual owners. On April 17, 2018, Slide Fire Solutions, the sole holder of the bump stock patent, announced that it would cease production of bump stocks as of May 20, though they did not state whether this was a temporary or permanent measure. It has temporarily suspended production before.

Luxury Yacht
A Luxury yacht (also super-yacht, large yacht and mega-yacht) is a very expensive, privately owned, professionally crewed sailing or motor yacht. There is no industry-wide standard for the difference between super-yacht and mega-yacht. The only legal distinction is between yachts above 24 metres (79 ft) and below, as in some countries those above 24 meters must have a permanent crew onboard. This term began to appear at the beginning of the 20th century, when wealthy individuals constructed large private yachts for personal pleasure, such as Charles Henry Fletcher's Jemima F. III, at 111 feet, the largest motor-powered yacht in the world in 1908. More examples of early luxury motor yachts include the Cox & King yachts, Charles L. Seabury and Company's yachts, M/Y (motor yacht) Christina O, and M/Y Savarona.

Application of Maturity-Models in Universities
A maturity model is a widely used tool in software engineering and has mostly been extended to domains such as education, health, energy, finance, government, and general use. It is valuable for evaluations and continuous improvement of business processes or certain aspects of organizations, as it represents a more organized and systematic way of doing business.  We present a Systematic Literature Review study of the elements and purposes of the maturity models applied to universities. Obtaining results that show the intention to evaluating the maturity of only some areas of the universities and not the whole, creating some gaps that do not allow to measure the desired level. It also shows how information technologies help its implementation in the field.

Stitched Textile Strain Sensors
By embedding conductive yarns in, or onto, knitted textile fabrics, simple but robust stretch sensor garments can be manufactured. In that way resistance based sensors can be fully integrated in textiles without compromising wearing comfort, stretchiness, washability, and ease of use in daily life. The many studies on such textile strain sensors that have been published in recent years show that these sensors work in principle, but closer inspection reveals that many of them still have severe practical limitations like a too narrow working range, lack of sensitivity, and undesired time-dependent and hysteresis effects. For those that intend to use this technology it is difficult to determine which manufacturing parameters, shape, stitch type, and materials to apply to realize a functional sensor for a given application.

First Assistant Engineer
A first assistant engineer (also called the second engineer in some countries) is a licensed member of the engineering department on a merchant vessel. This title is used for the person on a ship responsible for supervising the daily maintenance and operation of the engine department. They report directly to the chief engineer. On a merchant vessel, depending on term usage, "the First" or "the Second" is the marine engineer second in command of the engine department after the ship's chief engineer. Due to the supervisory role this engineer plays, in addition to being responsible for the refrigeration systems, main engines (steam/gas turbine, diesel), and any other equipment not assigned to the Second assistant engineer/third engineer or the Third assistant engineer/fourth engineer(s), he is typically the busiest engineer aboard the ship. If the engine room requires 24/7 attendance and other junior engineers can cover the three watch rotations, the first is usually a "day worker" from 0800-1700, with overtime hours varying according to ship/company. The first assistant/second engineer is usually in charge of preparing the engine room for arrival, departure, or standby and oversees major overhauls on critical equipment.

North–South Commuter Railway
The North–South Commuter Railway (NSCR), also known as the Clark–Calamba Railway, is a 148 km (92 mi) urban rail transit line being constructed in Luzon. It will run from New Clark City in Capas, Tarlac to Calamba, Laguna with 36 stations, with historic stations to be restored. Originally planned in the 1990s, the project has been repetitively halted after disagreements on funding and allegations of overpricing. The first proposal was the 32 km (20 mi) "Manila–Clark rapid railway" with Spain, and during the 2000s, the NorthRail project with China that was discontinued in 2011. The present line is under the Duterte administration and is to be aided with Japanese financing. It was initially reported to have a total length of 180 km (110 mi), though it was reduced to 148 kilometers (92 mi) after a segment to Los Baños was scrapped. The railway system is expected to cost ₱777.55 billion (US$14.95 billion), making it one of the most expensive projects of the Build! Build! Build! Infrastructure Program. Partial operations will begin by 2021, and full operations is expected to begin by 2025. The NSCR will comprise two sections corresponding to the Philippine National Railways' old main lines; the 91 km (57 mi) fully-elevated NSCR North which is being built over the mostly-defunct North Main Line in northern Metro Manila and Central Luzon, and the 56 km (35 mi) NSCR South which will use the existing PNR Metro Commuter Line infrastructure between Tutuban and Calamba, which were historically parts of the South Main Line and will have elevated, at-grade and depressed sections. The project's construction is divided into three phases with the NSCR North being separated between the 38 km (24 mi) NSCR North 1 commuter line between Tutuban and Malolos, and the 53 kilometres (33 mi) NSCR North 2 regional line from Malolos to New Clark City. It will also be linked to existing and future railway lines such as Line 8, Line 9, the Calamba–Bicol South Main Line and Calamba–Batangas City Railway.

Ionic Liquids in Drug Delivery
Ionic liquids (ILs) are molten salts composed of a large organic cation and an organic/inorganic anion. The large dimensions of their ions lead to charge dispersion, which makes difficult the formation of a regular crystalline structure. Due to their unique properties, ILs have been applied in the crystallization of active pharmaceutical ingredients (APIs), as solvents, co-solvents and emulsifiers in drug formulations, as pharmaceuticals (API-ILs) aiming liquid therapeutics, and in the development and/or improvement of drug-delivery-based systems.

Humanitarian Logistics
Although logistics has been mostly utilized in commercial supply chains, it is also an important tool in disaster relief operations. Humanitarian logistics is a branch of logistics which specializes in organizing the delivery and warehousing of supplies during natural disasters or complex emergencies to the affected area and people. However, this definition focuses only on the physical flow of goods to final destinations, and in reality, humanitarian logistics is far more complicated and includes forecasting and optimizing resources, managing inventory, and exchanging information. Thus, a good broader definition of humanitarian logistics is the process of planning, implementing and controlling the efficient, cost-effective flow and storage of goods and materials, as well as related information, from the point of origin to the point of consumption for the purpose of alleviating the suffering of vulnerable people. This figure presents numerous important aspects in humanitarian logistics, including transport, inventory management, infrastructure, and communications.
