Food Wastes as Packaging Materials
Packaging materials have to allow controlled respiration, maintain polymer structure against mechanical damage, prevent microbiological and chemical spoilage of food, and act as a selective gas and water vapor barrier. The most widely used materials in the food packaging industry are glass, plastics, metals, and paper. As mechanical properties of materials are important for food protection, mostly flexible and rigid synthetic packaging materials are preferred.

Working Capital
The simplest net working capital can be defined as the difference between the value of current assets and short-term liabilities together with other short-term accruals. It is equivalent to the part of the current assets financed with equity, provisions for liabilities, long-term liabilities, and the remaining part of accruals. Therefore, it is the capital that finances only that part of the current assets that are not financed with short-term liabilities. This amount is financed with fixed capital. Summing up, net working capital is the fixed capital that finances the company’s current assets.

Agri Food Sector
  Definition given the complexity of the sector, each supply chain has some peculiarities that require suitable tools. For this reason, it is difficult to identify a common tool for the implementation of circular practices. However, the use of a shared assessment tool should enable comparison of circular performances and practices among the different stages and supply chains and involving all the actors of the AFS. This collaborative approach is required both vertically (among the stages of the supply chain) and horizontally (among the different supply chains) in order to catalyse the transition towards circular business models and to efficiently implement circular practices.

High Entropy Alloys
High-entropy alloys (HEAs) are alloys that are formed by mixing equal or relatively large proportions of (usually) five or more elements. Prior to the synthesis of these substances, typical metal alloys comprised one or two major components with smaller amounts of other elements. For example, additional elements can be added to iron to improve its properties, thereby creating an iron based alloy, but typically in fairly low proportions, such as the proportions of carbon, manganese, and the like in various steels. Hence, high entropy alloys are a novel class of materials. The term “high-entropy alloys” was coined because the entropy increase of mixing is substantially higher when there is a larger number of elements in the mix, and their proportions are more nearly equal. These alloys are currently the focus of significant attention in materials science and engineering because they have potentially desirable properties. Furthermore, research indicates that some HEAs have considerably better strength-to-weight ratios, with a higher degree of fracture resistance, tensile strength, as well as corrosion and oxidation resistance than conventional alloys. Although HEAs have been studied since the 1980s, research substantially accelerated in the 2010s.

Projective Test
In psychology, a projective test is a personality test designed to let a person respond to ambiguous stimuli, presumably revealing hidden emotions and internal conflicts projected by the person into the test. This is sometimes contrasted with a so-called "objective test" / "self-report test", which adopt a "structured" approach as responses are analyzed according to a presumed universal standard (for example, a multiple choice exam), and are limited to the content of the test. The responses to projective tests are content analyzed for meaning rather than being based on presuppositions about meaning, as is the case with objective tests. Projective tests have their origins in psychoanalysis, which argues that humans have conscious and unconscious attitudes and motivations that are beyond or hidden from conscious awareness.

Smoothies
The word “smoothie” comes from the English term “smooth” (tender, creamy), and defines a creamy non-alcoholic drink with a thick texture similar to that of milkshakes. Smoothies are beverages containing a blend of fruit pulp, fruit juice, ice, yoghurt, and/or milk. This beverage includes only natural ingredients such as puree fruit with fruit juice, and possibly dairy products or/and crushed ice cubes. Their preparation is based on the use of the entire fruit, which is processed from pulp to puree, with only the seeds and peel being removed.

Water Droplet Erosion
The term erosion is originally derived from the Latin word “rodere”, which means “to gnaw”, and used to indicate a form of materials wear (i.e. loss of material) that is caused by the impact of solid or liquid particles with sufficiently high speed. Liquid erosion can be divided into two types; cavitation erosion and liquid impingement erosion (LIE). The term Water droplet erosion (WDE) is commonly used to indicate liquid impingement erosion (LIE), where a progressive material loss is caused by the repetitive impact of high speed water droplets. WDE constitutes a major concern in many industries including aerospace and aviation, power generation industries particularly in gas turbines and steam turbines, nuclear power plants, and wind energy. Hence, WDE has become an important topic of research.

Grandfather Paradox
The grandfather paradox is a paradox of time travel in which inconsistencies emerge through changing the past. The name comes from the paradox's description: a person travels to the past and kills their own grandfather before the conception of their father or mother, which prevents the time traveller's existence. Despite its title, the grandfather paradox does not exclusively regard the contradiction of killing one's own grandfather to prevent one's birth. Rather, the paradox regards any action that alters the past, since there is a contradiction whenever the past becomes different from the way it was.

Deontological Ethics
In moral philosophy, deontological ethics or deontology (from Greek: Ancient Greek: + Ancient Greek:) is the normative ethical theory that the morality of an action should be based on whether that action itself is right or wrong under a series of rules, rather than based on the consequences of the action. It is sometimes described as duty-, obligation-, or rule-based ethics. Deontological ethics is commonly contrasted to consequentialism, virtue ethics, and pragmatic ethics. In this terminology, action is more important than the consequences. The term deontological was first used to describe the current, specialised definition by C. D. Broad in his 1930 book, Five Types of Ethical Theory. Older usage of the term goes back to Jeremy Bentham, who coined it prior to 1816 as a synonym of dicastic or censorial ethics (i.e., ethics based on judgement). The more general sense of the word is retained in French, especially in the term code de déontologie (ethical code), in the context of professional ethics. Depending on the system of deontological ethics under consideration, a moral obligation may arise from an external or internal source, such as a set of rules inherent to the universe (ethical naturalism), religious law, or a set of personal or cultural values (any of which may be in conflict with personal desires).

Digital professionalism
Digital professionalism is the term used to describe the emergence of health professionals needing to understand, develop and know appropriate professional behaviour when using digital media. There is currently no accepted or standard definition of this term. The development of digital professionalism is a global issue, which is demonstrated by the growth in research of portable or mobile devices, social media, apps and messaging within health professional higher education and healthcare environments. Digital professionalism is a component of professional identity formation. The knowledge, skills, attitudes and behaviours associated with developing digital professionalism needs to be introduced early in the health professional curriculum, so that students understand the benefits as well as the risks and challenges of using digital technology at point of care. Modelling of safe, effective and appropriate access and use of mobile or portable devices by qualified health professionals is essential for scaffolding undergraduate health professionals understanding and development of appropriate attributes, to promote formation of positive professional identity when undertaking work integrated learning or professional experience in healthcare environments.

Histopathological Images
Histopathology is a significant branch of biology that covers the investigation of the cell anatomy and tissues of organisms at a microscopic level by a histopathologist. Histopathological images are very influential for the final decision procedure of effective therapeutics; these images are essential to investigate the status of a certain biological structure and to diagnose diseases like cancer . Digital histopathology represents a significant evolution in modern medicine. It often uses machine vision techniques as a basis. Nevertheless, because of the special properties of digital histopathology images and their processing tasks, specific processing approaches are usually needed.

Nandigram Violence
Nandigram Violence was violence occurred in Nandigram, East Midnapore, West Bengal, India , in 2007 due to the land acquisition for a project by the Government of West Bengal led by the Communist Party of India (Marxist) to create special economic zone (SEZ). The policy led to an emergency in the region, and 14 people died in a police shooting. According to CID reports, the Nandigram violence saw a Maoist insurgency in the area[lower-alpha 1] during the protests. But West Bengal Home Secretary himself stated that the presence of Maoists could not be confirmed in Nandigram. The Central Bureau of Investigation later exonerated the Buddhadeb Bhattacharya government of responsibility for the shootings. But supporting the violence in Nandigram by his own party workers, Buddhadeb Bhattacharya had said earlier "They (the oppositions) have been paid back in the same coin."

P5 (Microarchitecture)
The original Pentium microprocessor was introduced by Intel on March 22, 1993. It was instruction set compatible with the 80486 but was a new and very different microarchitecture design. The P5 Pentium was the first superscalar x86 microarchitecture and the world’s first superscalar microprocessor to be in mass production. It included dual integer pipelines, a faster floating-point unit, wider data bus, separate code and data caches as well as many other techniques and features to enhance performance and support security, encryption, and multiprocessing for workstations and servers. Considered the fifth main generation in the 8086 compatible line of processors, its implementation and microarchitecture was called P5. As with all new processors from Intel since the Pentium, some new instructions were added to enhance performance for specific types of workloads. The Pentium was the first Intel x86 to build in robust hardware support for multiprocessing similar to that of large IBM mainframe computers. Intel worked closely with IBM to define this capability and then Intel designed it into the P5 microarchitecture. This new capability was not present in prior x86 generations or x86 copies from competitors. In order to realize its greatest potential, compilers had to be optimized to take advantage of the instruction level parallelism provided by the new superscalar dual pipelines and applications needed to be recompiled. Intel spent substantial effort and resources working with development tool vendors, and major ISV and OS companies to optimize their products for Pentium prior to product launch. In October 1996, the similar Pentium MMX was introduced, complementing the same basic microarchitecture with the MMX instruction set, larger caches, and some other enhancements. Competitors included Motorola 68040, Motorola 68060, PowerPC 601, SPARC, MIPS, Alpha families, most of which also used a superscalar in-order dual instruction pipeline configuration at some time. Intel discontinued the P5 Pentium processors (sold as a cheaper product since the Pentium II of 1997) in early 2000 in favor of the Celeron processor, which had also replaced the 80486 brand.
