Quad Flat Package
A QFP or Quad Flat Package is a surface-mounted integrated circuit package with "gull wing" leads extending from each of the four sides. Socketing such packages is rare and through-hole mounting is not possible. Versions ranging from 32 to 304 pins with a pitch ranging from 0.4 to 1.0 mm are common. Other special variants include low-profile QFP (LQFP) and thin QFP (TQFP). The QFP component package type became common in Europe and United States during the early nineties, even though it has been used in Japan ese consumer electronics since the seventies. It is often mixed with hole mounted, and sometimes socketed, components on the same printed circuit board. A package related to QFP is PLCC which is similar but has pins with larger pitch, 1.27 mm (or 1/20 inch), curved up underneath a thicker body to simplify socketing (soldering is also possible). It is commonly used for NOR flash memories and other programmable components.

Weaponization of Finance
The term weaponization of finance refers to the foreign policy strategy of using incentives (access to capital markets) and penalties (varied types of sanctions) as tools of coercive diplomacy. The term was first coined by political scientists Ian Bremmer and Cliff Kupchan. It became one of the main themes of the Eurasia Group’s Top Risks 2015 report. It is a reference to the new ways in which the United States is using its influence to affect global outcomes. Rather than rely on traditional elements of America’s security advantage – including US-led alliances such as NATO and multi-lateral institutions such as the World Bank and the International Monetary Fund – Washington is now ‘weaponizing finance’ by limiting access to the US marketplace and US banks as an instrument of its foreign and security policy.

Electric Vehicles for Vehicle-to-Grid Services
With every passing second, we witness the effect of the global environmental impact of fossil fuels and carbon emissions, to which nations across the globe respond by coming up with ambitious goals to become carbon-free and energy-efficient. At the same time, electric vehicles (EVs) are developed as a possible solution to reach this ambitious goal of making a cleaner environment and facilitating smarter transportation modes. This excellent idea of shifting towards an entirely EV-based mobility industry and economy results in a range of issues that need to be addressed. The issues range from ramping up the electricity generation for the projected increase in consumption to developing an infrastructure that is large enough to support the higher demand for electricity that arises due to the market penetration of EVs. Vehicle to grid (V2G) is a concept that is largely in a testing phase in the current scenario. However, it appears to offer a solution to the issues created by a mobility sector that the constantly growing EV fleet will dominate. Furthermore, the integration of EVs with the grid seems to offer various cost-wise and environment-wise benefits while assisting the grid by tapping into the idle energy of parked EVs during peak hours

Great Disappointment
The Great Disappointment in the Millerite movement was the reaction that followed Baptist preacher William Miller's proclamations that Jesus Christ would return to the Earth by 1844, what he called the Advent. His study of the Daniel 8 prophecy during the Second Great Awakening led him to the conclusion that Daniel's "cleansing of the sanctuary" was cleansing of the world from sin when Christ would come, and he and many others prepared, but October 22, 1844 came, and they were disappointed. These events paved the way for the Adventists who formed the Seventh-day Adventist Church. They contended that what had happened on October 22 was not Jesus' return, as Miller had thought, but the start of Jesus' final work of atonement, the cleansing in the heavenly sanctuary, leading up to the Second Coming.

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.

Form of Action
The forms of action were the different procedures by which a legal claim could be made during much of the history of the English common law. Depending on the court, a plaintiff would purchase a writ in Chancery (or file a bill) which would set in motion a series of events eventually leading to a trial in one of the medieval common law courts. Each writ entailed a different set of procedures and remedies which together amounted to the "form of action". The forms of action were abolished during the 19th century, but they have left an indelible mark on the law. In the early Middle Ages, the focus was on the procedure that was employed to bring one's claim to the royal courts of King's Bench or Common Pleas: it was the form of one's action, not its substance, which occupied legal discussion. This restrictive approach is one of the reasons which attracted litigants to petition the King directly, which eventually led to the development of a separate court known as the Court of Chancery, from which the body of law known as equity derives. Modern English law, as in most other legal systems, now looks to substance rather than to form: a claimant need only demonstrate that he or she has a valid cause of action.

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.

Functional Mechanisms of Coding and Non-Coding Region SNPs
Cancer ranks as the second leading cause of death worldwide, and, being a genetic disease, it is highly heritable. Over the past few decades, genome-wide association studies (GWAS) have identified many risk-associated loci harboring hundreds of single nucleotide polymorphisms (SNPs). Some of these cancer-associated SNPs have been revealed as causal, and the functional characterization of the mechanisms underlying the cancer risk association has been illuminated in some instances.

Extra Virgin Olive Oil
Extra virgin olive oil (EVOO) is responsible for a large part of many health benefits associated with Mediterranean diet as it is a fundamental ingredient of this diet. The peculiarities of this golden highly valued product are in part due to the requirements that must be met to achieve this title, namely, it has to be obtained using exclusively mechanical procedures, its free acidity cannot be greater than 0.8%, it must not show sensory defects and it has to possess a fruity taste. All these characteristics are key factors to EVOO quality, thus the chemical composition of these many health-promoting compounds, such as unsaturated fatty acids (which are also the major compounds, especially oleic acid), as well as minor components such as tocopherols or phenolic compounds (which behave as natural antioxidants) must be preserved. Due to the presence of all these compounds, the daily consumption of EVOO entails health benefits such as cardioprotective, antioxidant, anti-inflammatory, anti-tumor properties or acting as regulators of the intestinal microbiota, among others. Taking all together, conserving EVOO chemical composition is essential to preserve its properties, so it is worth to control certain factors during storage like exposure to light, temperature, oxygen presence or the chosen packaging material, to maintain its quality and extend its shelf-life until its consumption.

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.

Spawn
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, to spawn refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and reptiles, reproduce through the process of spawning. Spawn consists of the reproductive cells (gametes) of many aquatic animals, some of which will become fertilized and produce offspring. The process of spawning typically involves females releasing ova (unfertilized eggs) into the water, often in large quantities, while males simultaneously or sequentially release spermatozoa (milt) to fertilize the eggs. Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mosquitoes and corals, which are actually small aquatic animals—not plants. Fungi, such as mushrooms, are also said to "spawn" a white, fibrous matter that forms the matrix from which they grow. There are many variations in the way spawning occurs, depending on sexual differences in anatomy, how the sexes relate to each other, where and how the spawn is released and whether or how the spawn is subsequently guarded.

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.

Dielectric Materials
Owing to their insulating properties, dielectric materials are known as electrically insulating materials. According to the different dielectric materials, traditional dielectric capacitors can be divided into three categories. Firstly, there are polymer-based dielectric capacitors. The dielectric materials of this type of capacitors are mainly polymer materials. Second, there are ceramic-based dielectric capacitors. The dielectric materials of such capacitors include multi-phase ceramics, glass ceramics, ceramic films, etc. Third is the polymer ceramic composite dielectric capacitors, using a variety of polymer and ceramic composite materials as storage medium.

Revenge
Revenge is defined as the act of committing a harmful action against a person or group in response to a grievance, be it real or perceived. Francis Bacon described revenge as a kind of "wild justice" that "does... offend the law [and] putteth the law out of office." Primitive justice or retributive justice is often differentiated from more formal and refined forms of justice such as distributive justice and divine judgment.
