Satellite Geodesy
Satellite geodesy is geodesy by means of artificial satellites — the measurement of the form and dimensions of Earth, the location of objects on its surface and the figure of the Earth's gravity field by means of artificial satellite techniques. It belongs to the broader field of space geodesy. Traditional astronomical geodesy is not commonly considered a part of satellite geodesy, although there is considerable overlap between the techniques. The main goals of satellite geodesy are: Satellite geodetic data and methods can be applied to diverse fields such as navigation, hydrography, oceanography and geophysics. Satellite geodesy relies heavily on orbital mechanics.

Single-Component Cationic Photoinitiators
With the advantages offered by cationic photopolymerization (CP) such as broad wavelength activation, tolerance to oxygen, low shrinkage and the possibility of “dark cure”, it has attracted extensive attention in photoresist, deep curing and other fields in recent years. The applied photoinitiating systems (PIS) play a crucial role as they can affect the speed and type of the polymerization and properties of the materials formed. Much effort has been invested into developing cationic photoinitiating systems (CPISs) that can be activated at long wavelengths and overcome technical problems and challenges faced.

Roll Bonding Processes
The roll bonding (RB) process involves joining of two or more sheets of similar or dissimilar materials at various temperatures. The process requires rolling through a pair of rollers under adequate pressure resulting in the bonding of sheets. The process is categorized into three types, i.e., cold, hot, and warm roll bonding based on the ranges of the processing temperature which in turn is related to the recrystallization temperature.

Nikolaas Tinbergen
Nikolaas "Niko" Tinbergen FRS (/ˈtɪnbɜːrɡən/; Dutch: [ˈnikoːlaːs ˈnikoː ˈtɪnbɛrɣən]; 15 April 1907 – 21 December 1988) was a Dutch biologist and ornithologist who shared the 1973 Nobel Prize in Physiology or Medicine with Karl von Frisch and Konrad Lorenz for their discoveries concerning organization and elicitation of individual and social behavior patterns in animals. He is regarded as one of the founders of modern ethology, the study of animal behavior. In 1951, he published The Study of Instinct, an influential book on animal behaviour. In the 1960s, he collaborated with filmmaker Hugh Falkus on a series of wildlife films, including The Riddle of the Rook (1972) and Signals for Survival (1969), which won the Italia prize in that year and the American blue ribbon in 1971.

List of Minerals U–V (Complete)
This list includes those recognised minerals beginning with the letters U and V. The International Mineralogical Association is the international group that recognises new minerals and new mineral names, however minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date. This list contains a mixture of mineral names that have been approved since 1959 and those mineral names believed to still refer to valid mineral species (these are called "grandfathered" species). The list is divided into groups: The data was exported from mindat.org on 29 April 2005; updated up to 'IMA2018'. The minerals are sorted by name, followed by the structural group (rruff.info/ima and ima-cnmnc by mineralienatlas.de, mainly) or chemical class (mindat.org and basics), the year of publication (if it's before of an IMA approval procedure), the IMA approval and the Nickel–Strunz code. The first link is to mindat.org, the second link is to webmineral.com, and the third is to the Handbook of Mineralogy (Mineralogical Society of America).

Economic Connectivity Processes
The term “economic connectivity” refers to various forms of economic relationships between states or groups of states in the areas of, for example, trade, business activities, finances, technology, and migration. Economic connectivity, a common feature of modern society, is characterized by various political and economic interactions and can be understood in at least two major forms. The first, including transport, communication, and energy infrastructure, is “hard” economic connectivity, while regulatory, institutional, and legal instruments or knowledge, culture, and understanding shape “soft” economic connectivity.

Electricity Tariffs and Solutions for Optimal Energy Management
Today, electricity tariffs play an essential role in the electricity retail market as they are the key factor for the decision-making of end-users. Additionally, tariffs are necessary for increasing competition in the electricity market. They have a great impact on load energy management. Moreover, tariffs are not taken as a fixed approach to expense calculations only but are influenced by many other factors, such as electricity generation, transmission, distribution costs, and governmental taxation. Thus, electricity pricing differs significantly between countries or between regions within a country. Improper tariff calculation methodologies in some areas have led to high-power losses, unnecessary investments, increased operational expenses, and environmental pollution due to the non-use of available sustainable energy resources.

Prediction of Water Quality Classification using Machine Learning
Machine Learning (ML) has been used for a long time and has gained wide attention over the last several years. It can handle a large amount of data and allow non-linear structures by using complex mathematical computations. However, traditional ML models do suffer some problems, such as high bias and overfitting. Therefore, this has resulted in the advancement and improvement of ML techniques, such as the bagging and boosting approach, to address these problems.

Romansh Language
Romansh is a Romance language spoken in the Graubünden canton of eastern Switzerland, and is one of the official languages of the country. It is the native language of about 40,000 Swiss people and, of the major Romance languages, is most closely related to French. However, the accent and writing system of its speakers appear to the casual observer to more closely resemble Italian and German – a significant fact in historical conflicts over the region. Romansh is actually an umbrella term for several dialects, with each speech community in the region using different names for them. The term ‘Romansh’ is itself an anglicisation of the various local language names, including Romansch in German, and Rumantsch in Romansh itself. It is most closely related to Ladin and Friulian, varieties spoken in northern Italy, and together these form the Rhaeto-Romance sub-family of Gallo-Romance, a larger group that includes French and various varieties of northern Italy. These are only distantly related to standard Italian. 'Rhaeto-Romance' is sometimes considered a single language, and its three varieties dialects, and on occasions, 'Ladin' has been used to mean any or all of these.

Epoch (Reference Date)
In the fields of chronology and periodization, an epoch is an instant in time chosen as the origin of a particular era. The "epoch" then serves as a reference point from which time is measured. Time measurement units are counted from the epoch so that the date and time of events can be specified unambiguously. Events taking place before the epoch can be dated by counting negatively from the epoch, though in pragmatic periodization practice, epochs are defined for the past, and another epoch is used to start the next era, therefore serving as the ending of the older preceding era. The whole purpose and criteria of such definitions are to clarify and co-ordinate scholarship about a period, at times, across disciplines. Epochs are generally chosen to be convenient or significant by a consensus of the time scale's initial users, or by authoritarian fiat. The epoch moment or date is usually defined by a specific clear event, condition, or criterion—the epoch event or epoch criterion—from which the period or era or age is usually characterized or described.

Microgrid Operation Mode and Architectures
Energy security and the resilience of electricity networks have gained critical momentum as subjects of research. The challenges of meeting the increasing electrical energy demands and the decarbonisation efforts necessary to mitigate the effects of climate change have highlighted the importance of microgrids for the effective integration of renewable energy sources. Microgrids (MGs) can operate in grid-connected and islanded operation. MG architectures are categorised as alternating current microgrid (ACMG), direct current microgrid (DCMG) and hybrid microgrid (HMG).

Environmental Intelligence
We propose that coupled human and environmental information processing can be applied to concomitantly increase the scope and penetration of surveillance, leading to new opportunities to detect, track, quantify, predict and influence events and interactions across a wide range of operations. Academia and non-governmental organizations, state actors, and commercial interests are expected to utilize and benefit from environmental intelligence in differentiated manners.

Urinary Tract Infections
Urinary tract infections (UTIs) affect any part of the urinary tract and may spread through the urinary tract towards the urethra, bladder and even the kidneys and they are associated with an increase in morbidity and mortality. UTIs may be resolved spontaneously or treated with antibiotics. However, regular use of antibiotics is related to nephrotoxicity and  produces changes in the intestinal flora, alter immunity and metabolism, and finally, gut bacteria become a reservoir of genes for resistance to antibiotics. Regarding this concern, a new group of molecules called drug conjugates have been proposed as an alternative or a complement to de use of just antibiotics such as a new adjuvant in UTIs therapy called Itxasol©.

Opportunities and Challenges in Developing Ocean Energy Sources
The optimal utilization of renewable energies is a crucial factor toward the realization of sustainability and zero carbon in a future energy system. Tidal currents, waves, and thermal and salinity gradients in the ocean are excellent renewable energy sources. Ocean tidal, osmotic, wave, and thermal energy sources have yearly potentials that exceed the global power demand of 22,848 TWh/y. It is expected that a better insight into ocean energy and a deep understanding of various potential devices can lead to a broader adoption of ocean energy. It is also clear that further research into control strategies is needed. Policy makers should provide financial support for technologies in the demonstration stage and employ road mapping to accelerate the cost and risk reductions to overcome economic hurdles.

The Balancing Act of Repurposing Feature Films and TV Series for University Teaching
Contemporary educators have increasingly recognised the diversity of their student population and, hence, have attempted to use multimodal teaching methods for additional student learning benefits. One popular example is repurposing film and TV content for higher education pedagogies. However, integrating these materials into teaching effectively often proves more complex than lecturers might anticipate. This entry investigates the merits and challenges of using FF/TV in teaching to determine the factors that impact development of an effective FF/TV pedagogy for student learning, through an interdisciplinary review of the existing literature, followed by a qualitative survey and semi-structured interviews with lecturers across disciplines at Australian universities. Using visual literacy theory, cognitive load theory, and dual coding theory, data analysis reveals that the pros and cons of integrating film and TV in teaching are in fact interconnected, and the main role of the teacher is to pedagogically balance them. Evidence-based and theory-grounded suggestions for application are detailed throughout the discussions.

Adhesion in Bitumen/Aggregate System
The five main theories describing the interaction mechanisms in the bitumen/aggregate system was conducted: theory of weak boundary layers, mechanical theory, electrostatic theory, chemical bonding theory, and thermodynamic theory (adsorption theory). The adhesion assessment methods in the bitumen/aggregate system are described, which can be divided into three main groups: determination of adhesion forces for bitumen with different materials, determination of bitumen resistance to the exfoliating action of water with different materials, and determination of adhesion as a fundamental value (contact angle measurements, interfacial fracture energy, adsorption capacity and others).
