Ferdinand II of Aragon (1479–1516)
Ferdinand II king of Aragon (1479–1516). He was the fourth king of the Trastámara dynasty, which had first come to power after the Compromise of Caspe, reached after Martin I died with no living descendants in 1410. Although in terms of artistic patronage Ferdinand II was not as active as his wife Elisabeth I, he was still aware that the wise use of artistic commissions in reinforcing ideas and concepts favourable to the institution of the monarchy. He is a highly important figure in the history of Spain because, along with Elisabeth, he was one of the Catholic Monarchs and thus represents a new conception of power based on their joint governance, a fact that is reflected in the iconography found in his artistic commissions across all genres. All of the images are evidence of how King Ferdinand, at the end of the Middle Ages, wanted to be recognised by his subjects, who also used his image for legitimising and propagandistic purposes. Nobody else in the history of the Hispanic kingdoms had their image represented so many times and on such diverse occasions as did the Catholic Monarchs.

1G and 2G Bioethanol Production
First-generation (1G) bioethanol is one of the most used liquid biofuels in the transport industry. It is generated by using sugar- or starch-based feedstocks, while second-generation (2G) bioethanol is generated by using lignocellulosic feedstocks. Distillers’ dried grains with solubles (DDGS) is a byproduct of first-generation bioethanol production with a current annual production of 22.6 million tons in the USA. DDGS is rich in fiber and valuable nutrients contents, which can be used to produce lignocellulolytic enzymes such as cellulases and hemicellulases for 2G bioethanol production.

Khosrow II (590–628 CE)
Khosrow II (r. 590–628 CE) was the last great Sasanian king who took the throne with the help of the Romans and broke with dynastic religious preferences as he became married to a Christian empress. It was under his rule that the Sasanian Empire reached its greatest expansion. From the standpoint of iconographic studies, Khosrow II is among the most influential Persian kings. Although he was literally occupied by rebels and wars within the borders of the Sasanian territories and beyond, Khosrow managed to create a powerful image of himself that emphasized the legitimacy of his monarchy. Indeed, Khosrow Parviz (the Victorious) drew upon royal iconography as a propaganda tool on a wide range of materials such as rock and stucco reliefs, coins, seals, and metal plates. His image (created both visually and verbally) not only revived the traditional iconography of the Persian kings but also evolved it in a way that transcended his time and was passed on to the early Islamic Caliphates after him. Khosrow II imitated and manipulated the traditional royal iconography of his predecessors in order to display his legitimacy, piety, and valor.

Adolescence
Adolescence (from la adolescere 'to grow up') is a transitional stage of physical and psychological development that generally occurs during the period from puberty to legal adulthood (age of majority). Adolescence is usually associated with the teenage years, but its physical, psychological or cultural expressions may begin earlier and end later. For example, puberty now typically begins during preadolescence, particularly in females. Physical growth (particularly in males), and cognitive development can extend into the early twenties. Thus age provides only a rough marker of adolescence, and scholars have found it difficult to agree upon a precise definition of adolescence. A thorough understanding of adolescence in society depends on information from various perspectives, including psychology, biology, history, sociology, education, and anthropology. Within all of these perspectives, adolescence is viewed as a transitional period between childhood and adulthood, whose cultural purpose is the preparation of children for adult roles. It is a period of multiple transitions involving education, training, employment and unemployment, as well as transitions from one living circumstance to another. The end of adolescence and the beginning of adulthood varies by country. Furthermore, even within a single nation state or culture there can be different ages at which an individual is considered mature enough for society to entrust them with certain privileges and responsibilities. Such privileges and responsibilities include driving a vehicle, having legal sexual relations, serving in the armed forces or on a jury, purchasing and drinking alcohol, voting, entering into contracts, finishing certain levels of education, marriage, and accountability for upholding the law. Adolescence is usually accompanied by an increased independence allowed by the parents or legal guardians, including less supervision as compared to preadolescence. In studying adolescent development, adolescence can be defined biologically, as the physical transition marked by the onset of puberty and the termination of physical growth; cognitively, as changes in the ability to think abstractly and multi-dimensionally; or socially, as a period of preparation for adult roles. Major pubertal and biological changes include changes to the sex organs, height, weight, and muscle mass, as well as major changes in brain structure and organization. Cognitive advances encompass both increment in knowledge and in the ability to think abstractly and to reason more effectively. The study of adolescent development often involves interdisciplinary collaborations. For example, researchers in neuroscience or bio-behavioral health might focus on pubertal changes in brain structure and its effects on cognition or social relations. Sociologists interested in adolescence might focus on the acquisition of social roles (e.g., worker or romantic partner) and how this varies across cultures or social conditions. Developmental psychologists might focus on changes in relations with parents and peers as a function of school structure and pubertal status. Some scientists have questioned the universality of adolescence as a developmental phase, arguing that traits often considered typical of adolescents are not in fact inherent to the teenage years.

Ghauri (Missile)
The Ghauri–I (Urdu: غوری-ا‎; official codename: Hatf–5 Ghauri–I) is a land-based surface-to-surface medium-range ballistic missile, in current service with the Pakistan Army's Strategic Forces Command— a subordinate command of Strategic Plans Division. Influenced from the design of Nodong-1 of North Korea, its extensive modification and engineering took place in Kahuta Research Laboratories (KRL) in 1990s with an objective of developing an electronic system that uses a single stage liquid fuel rocket motor to carry a payload of 700 kg to a range of 1,500 km. This is enough to reach most, if not all of India. Two variants of the Ghauri were produced under the secretive missile research programme started in 1987 and the development of a third variant was cancelled. The Ghauri-II uses increased motor assembly length and improved propellants for an increased range of 2,300 km (1,400 mi). The missile is named after Shahabuddin Muhammad Ghauri, while the "Hatf" designation originates from the name of the sword or lance of the Islamic prophet Muhammad.

Causes of Transsexuality
The study of the causes of transsexuality investigates gender identity formation of transgender people, especially those who are transsexual. Transgender people have a gender identity that does not match their assigned sex, often resulting in gender dysphoria. The causes of transsexuality have been studied for decades. The most studied factors are biological, especially brain structure differences in relation to biology and sexual orientation. Environmental factors have also been proposed. Transgender brain studies, especially those on trans women who are sexually attracted to women (gynephilic), and those on trans men who are sexually attracted to men (androphilic), are limited, as they include a small number of tested individuals. The available research indicates that the brain structure of androphilic trans women with early-onset gender dysphoria is closer to the brain structure of cisgender women's and less like cisgender men's. It also reports that both androphilic trans women and trans women with late-onset gender dysphoria who are gynephilic have different brain phenotypes, and that gynephilic trans women differ from both cisgender female and male controls in non-dimorphic brain areas. Cortical thickness, which is generally thicker in cisgender women's brains than in cisgender men's brains, may also be thicker in trans women's brains, but is present in a different location to cisgender women's brains. For trans men, research indicates that those with early-onset gender dysphoria and who are gynephilic have brains that generally correspond to their assigned sex, but that they have their own phenotype with respect to cortical thickness, subcortical structures, and white matter microstructure, especially in the right hemisphere. Hormone use can also affect transgender people's brain structure; it can cause transgender women's brains to become closer to those of cisgender women, and morphological increments observed in the brains of trans men might be due to the anabolic effects of testosterone. Twin studies suggest that there are likely genetic causes of transsexuality, although the precise genes involved are not fully understood. One study published in the International Journal of Transgender Health found that 20% of identical twin pairs in which at least one twin was trans were both trans, compared to only 2.6% of non-identical twins who were raised in the same family at the same time, but were not genetically identical. Ray Blanchard created a taxonomy of male-to-female transsexualism that proposes two distinct etiologies for androphilic and gynephilic individuals that has become controversial, supported by J. Michael Bailey, Anne Lawrence, James Cantor and others, but opposed by Charles Allen Moser, Julia Serano, and the World Professional Association for Transgender Health.

Celebrity Worship Syndrome
Celebrity worship syndrome (CWS) is an obsessive addictive disorder in which a person becomes overly involved with the details of a celebrity's personal and professional life. Psychologists have indicated that though many people obsess over film, television, sport and pop stars, the only common factor between them is that they are all figures in the public eye. Written observations of celebrity worship date back to the 19th century.

Pre-Existence
Pre-existence, preexistence, beforelife, or premortal existence refers to the belief that each individual human soul existed before mortal conception, and at some point before birth enters or is placed into the body. Concepts of pre-existence can encompass either the belief that the soul came into existence at some time prior to conception or the belief that the soul is eternal. Alternative positions are traducianism and creationism, which both hold that the individual human soul does not come into existence until conception. It is to be distinguished from preformation, which is about physical existence and applies to all living things. Ancient Greek thought and Islam affirm pre-existence, but it is generally denied in Christianity.

Stress–Energy Tensor
The stress–energy tensor, sometimes called the stress–energy–momentum tensor or the energy–momentum tensor, is a tensor quantity in physics that describes the density and flux of energy and momentum in spacetime, generalizing the stress tensor of Newtonian physics. It is an attribute of matter, radiation, and non-gravitational force fields. This density and flux of energy and momentum are the sources of the gravitational field in the Einstein field equations of general relativity, just as mass density is the source of such a field in Newtonian gravity.

Reflective Practice
Reflective practice is the ability to reflect on one's actions so as to engage in a process of continuous learning. According to one definition it involves "paying critical attention to the practical values and theories which inform everyday actions, by examining practice reflectively and reflexively. This leads to developmental insight". A key rationale for reflective practice is that experience alone does not necessarily lead to learning; deliberate reflection on experience is essential. Reflective practice can be an important tool in practice-based professional learning settings where people learn from their own professional experiences, rather than from formal learning or knowledge transfer. It may be the most important source of personal professional development and improvement. It is also an important way to bring together theory and practice; through reflection a person is able to see and label forms of thought and theory within the context of his or her work. A person who reflects throughout his or her practice is not just looking back on past actions and events, but is taking a conscious look at emotions, experiences, actions, and responses, and using that information to add to his or her existing knowledge base and reach a higher level of understanding.

Grievance Studies Affair
The Grievance Studies affair, also referred to as "hoax" or the "Sokal Squared" scandal (in reference to a similar 1996 hoax), was an attempt by a team of three authors (James A. Lindsay, Peter Boghossian, and Helen Pluckrose) to create bogus academic papers and submit them to academic journals with the intent of testing the strength of the editorial and peer review process. The hoax began in 2017 and ended in 2018. The authors targeted the academic areas of cultural, race, gender, fat, and sexuality studies in which they believed poor science was undermining the field, which they collectively refer to as "grievance studies". The project was halted early after one of the papers was criticized on social media, then its authenticity questioned on Campus Reform, and finally the hoax being more broadly exposed by the Wall Street Journal in 2018 alongside a YouTube video created and released by documentary filmmaker Mike Nayna. By the time of the reveal, four of their 20 papers had been published, one had won an award, three had been accepted but not yet published, six had been rejected, and seven were still under review.

Terminology of the British Isles
The terminology of the British Isles refers to the various words and phrases that are used to describe the different (and sometimes overlapping) geographical and political areas of the islands of Great Britain, Ireland, and the smaller islands which surround them. The terminology is often a source of confusion, partly owing to the similarity between some of the actual words used, but also because they are often used loosely. In addition, many of the words carry both geographical and political connotations which are affected by the history of the islands. The purpose of this article is to explain the meanings of and relationships among the terms in use; however many of these classifications are contentious and are the subject of disagreement (See the British Isles naming dispute).

SpaceX Mars Transportation Infrastructure
Elon Musk and SpaceX have proposed the development of Mars transportation infrastructure in order to facilitate the eventual colonization of Mars. The mission architecture includes fully reusable launch vehicles, human-rated spacecraft, on-orbit propellant tankers, rapid-turnaround launch/landing mounts, and local production of rocket fuel on Mars via in situ resource utilization (ISRU). SpaceX's aspirational goal since 2017 has been to land the first humans on Mars by 2024. A key element of the infrastructure is planned to be the SpaceX Starship, a fully reusable space vehicle under development since 2018. To achieve a large payload, the spacecraft would first enter Earth orbit, where it is expected to be refueled before it departs to Mars. After landing on Mars, the spacecraft would be loaded with locally-produced propellants to return to Earth. The expected payload for the Starship/Super Heavy is to inject between 100–150 tonnes (220,000–330,000 lb) to Mars. SpaceX intends to concentrate its resources on the transportation part of the Mars colonization project, including the design of a propellant plant based on the Sabatier process that will be deployed on Mars to synthesize methane and liquid oxygen as rocket propellants from the local supply of atmospheric carbon dioxide and ground-accessible water ice. However, Musk has advocated since 2016 a larger set of long-term Mars settlement objectives, going far beyond what SpaceX projects to build; any successful colonization would ultimately involve many more economic actors—whether individuals, companies, or governments—to facilitate the growth of the human presence on Mars over many decades.

SSC Aero
The SSC Ultimate Aero is a mid-engined sports car that was produced by SSC North America (formerly known as Shelby SuperCars) from 2004 until 2013. The SSC Ultimate Aero held the world production car speed record title, according to the Guinness World Records, from 2007 (when it was officially timed at 410 km/h) until the introduction of the Bugatti Veyron Super Sport in 2010. In April 2013, the Guinness World Records temporarily disqualified the Veyron's record time for a period of five days due to concerns about electronic speed limiting changing the function of the car, but after investigation reinstated the Veyron as the record holder. The SSC Ultimate Aero was not sold with electronic driver aids such as an anti-lock braking system or traction control system, as according to Jerod Shelby (no relations to Carroll Shelby), "Early design philosophy on the car was to make it a driver's car. I wanted a car that you not only throttled with your right foot but at times you could steer with your right foot and a sensor."

Intelligent Tutoring System
An intelligent tutoring system (ITS) is a computer system that aims to provide immediate and customized instruction or feedback to learners, usually without requiring intervention from a human teacher. ITSs have the common goal of enabling learning in a meaningful and effective manner by using a variety of computing technologies. There are many examples of ITSs being used in both formal education and professional settings in which they have demonstrated their capabilities and limitations. There is a close relationship between intelligent tutoring, cognitive learning theories and design; and there is ongoing research to improve the effectiveness of ITS. An ITS typically aims to replicate the demonstrated benefits of one-to-one, personalized tutoring, in contexts where students would otherwise have access to one-to-many instruction from a single teacher (e.g., classroom lectures), or no teacher at all (e.g., online homework). ITSs are often designed with the goal of providing access to high quality education to each and every student.
