Hydrogen Economy
Environmental issues make the quest for better and cleaner energy sources a priority. Worldwide, researchers and companies are continuously working on this matter, taking one of two approaches: either finding new energy sources or improving the efficiency of existing ones. Hydrogen is a well-known energy carrier due to its high energy content, but a somewhat elusive one for being a gas with low molecular weight. The so-called "Hydrogen Economy" is based on the use of hydrogen as an energy source. This entry examines the current electrolysis processes for obtaining hydrogen, with an emphasis on alkaline water electrolysis.

Enzymatic Interesterification
Enzymatic Interesterification (EIE) is the catalytic reaction that occurs when an enzyme is introduced into oil and rearranges the fatty acids on the glycerol backbone of a triglyceride. Triglycerides are either liquid or solid at room temperature. The rearrangement of the fatty acids that occurs with enzymatic interesterification provides structure and functionality to triglycerides at room temperature. This process adjusts the melting properties, increasing functionality and plasticity in food production applications. One of five different ways of altering melting property profiles, enzymatic interesterification is unlike the more widely used partial hydrogenation method in that it produces no trans fatty acids and lowers saturated fat content.

Outcome-Based Education
Outcome-based education or outcomes-based education (OBE) is an educational theory that bases each part of an educational system around goals (outcomes). By the end of the educational experience, each student should have achieved the goal. There is no single specified style of teaching or assessment in OBE; instead, classes, opportunities, and assessments should all help students achieve the specified outcomes. The role of the faculty adapts into instructor, trainer, facilitator, and/or mentor based on the outcomes targeted. Outcome-based methods have been adopted in education systems around the world, at multiple levels. Australia and South Africa adopted OBE policies from the 1990s to the mid 2000s, but were abandoned in the face of substantial community opposition. The United States has had an OBE program in place since 1994 that has been adapted over the years. In 2005, Hong Kong adopted an outcome-based approach for its universities. Malaysia implemented OBE in all of their public schools systems in 2008. The European Union has proposed an education shift to focus on outcomes, across the EU. In an international effort to accept OBE, The Washington Accord was created in 1989; it is an agreement to accept undergraduate engineering degrees that were obtained using OBE methods. As of 2017, the full signatories are Australia, Canada, Taiwan, Hong Kong, India, Ireland, Japan, Korea, Malaysia, New Zealand, Russia, Singapore, South Africa, Sri Lanka, Turkey, the United Kingdom, Pakistan, China and the United States.

Collaborationism
Collaborationism is cooperation with the enemy against one's country of citizenship in wartime. The term is most often used to describe the cooperation of civilians with the occupying Axis Powers, especially Nazi Germany, Fascist Italy, and Imperial Japan, during World War II. Motivations for collaboration by citizens and organizations included nationalism, ethnic hatred, anti-communism, antisemitism, opportunism, self-defense, or often a combination of these factors. Some collaborators in World War II committed war crimes, crimes against humanity, or atrocities such as the Holocaust. More often collaborators simply "went along to get along," attempting to benefit from the occupation or simply survive. The definition of collaborationism is imprecise and subject to interpretation. Stanley Hoffmann subdivided collaboration into involuntary (reluctant recognition of necessity) and voluntary (an attempt to exploit necessity). According to him, collaborationism can be either servile or ideological. Servile is service to an enemy based on necessity for personal survival or comfort, whereas ideological is advocacy for cooperation with an enemy power. In contrast, Bertram Gordon used the terms "collaborator" and "collaborationist" for non-ideological and ideological collaborations, respectively. James Mace Ward has asserted that, while collaboration is often equated with treason, there was "legitimate collaboration" between civilian internees (mostly Americans) in the Philippines and their Japanese captors for mutual benefit and to enhance the possibilities of the internees to survive. Collaboration with the Axis Powers in Europe and Asia existed in varying degrees in all the occupied countries. Although the United Kingdom and the United States were never occupied, a British dependency, the Channel Islands near France, was under German occupation and thousands of American civilians in Asia were interned by Japan. With the defeat of the Axis, collaborators were often punished by public humiliation, imprisonment, and execution. In France, 10,500 collaborators are estimated to have been executed, some after legal proceedings, others extrajudicially. The opposite of collaborationism in World War II was "resistance", a term which also has a broad range of meaning and interpretations.

Hybrid Microgrid System
A novel energy management system for a hybrid microgrid has been developed that uses a new control algorithm termed Inefficient Power Conversion Elimination Algorithm (IPCEA). The proposed algorithm compares the Net Transferable Power (NTP) available at the DC side with the loss rate across the converter. The converter is switched off (or disconnected from the grid and load) if the NTP is less than 20% of the converter rating to avoid low-efficiency power conversion. The solar PV system is connected to the DC bus to supply the DC loads while the AC loads are supplied from the AC source (utility power). An auxiliary battery pack has been integrated to the DC side to feed DC loads during the absence of solar energy. Battery Energy Storage System (BESS) has been deployed to manage energy distribution effectively. Power distribution is managed using a centralized microgrid controller, and the load demand is met accordingly. Thereby, power generated by solar PV can be utilized effectively. Microgrid technology's effectiveness is emphasized by comparative analysis, and the achievements have been discussed in detail and highlighted using a prototype model. The proposed study intends to design a novel switching strategy to incorporate a hybrid microgrid in the distribution system effectively. It comprises the following conventional electrical installation with an intelligent microgrid distribution system: i) To implement a renewable-based IPCEA considering the availability of Net Transferable Power (NTP) at DC bus and the rate of converter loss to minimize low efficient power conversion. ii) To effectively manage battery energy within the DC side of the microgrid to minimize the charge cycle and improve its performance.  iii) To decrease the stress on the utility grid by reducing the rate of power exchange.

Leaf area index (LAI)
Leaf area index (LAI) is an important vegetation leaf structure parameter in forest and agricultural ecosystems. Remote sensing techniques can provide an effective alternative to field-based observation of LAI. Different system configurations (passive, active, and multisource sensors on different collection platforms) has been used to estimate forest and crop LAI. The ease of use of empirical models supports these as the preferred choice for forest and crop LAI estimation. In terms of scale issues, both spectral and spatial scales impact the estimation of LAI. Uncertainty coming from various sources results in reduced accuracy in estimating LAI.

Post-Truth
Post-truth is a philosophical and political concept for "the disappearance of shared objective standards for truth" and the "circuitous slippage between facts or alt-facts, knowledge, opinion, belief, and truth". Post-truth discourse is often contrasted with the forms taken by scientific methods and inquiry. The term garnered widespread popularity, in the form of "post-truth politics", in the period around the 2016 United States presidential election and the Brexit referendum. It was named Word of the Year in 2016 by the Oxford Dictionary where it is defined as "Relating to or denoting circumstances in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief". While the term post-truth is relatively recent, the concept can be traced back to earlier moral, epistemic, and political debates about relativism, postmodernity, and mendacity in politics, including nontruthfulness, lies, deception, and deliberate falsehood.

Applicability of Essential Oils in Food Products
Essential oils (EOs) are extracted from plants and exhibit antimicrobial (antibacterial and antifungal) activity; thus, they are used in food products to prolong the shelf-life of foods by limiting the growth or survival of microorganisms. In vitro studies have shown that EOs are effective against foodborne bacteria, such as Escherichia coli, Listeria monocytogenes, Salmonella spp., and Staphylococcus aureus. The growing interest in essential oils and their constituents as alternatives to synthetic preservatives has been extensively exploited in recent years, along with techniques to facilitate the implementation of their application in the food industry.

Effects of Enclosure Complexity on Zoo Animals
Habitat complexity is important for the maintenance of high levels of welfare for captive animals, especially at zoos. Generally, individuals who experience greater enclosure complexity express higher diversity of behaviours and show better physiological well-being. However, positive outcomes of providing habitat complexity should be species-specific, and not all species would benefit from it. Thus, it is important to provide and constantly evaluate the habitat complexity of zoo animals.

Dyscalculia
Dyscalculia (/ˌdɪskælˈkjuːliə/) is a disability resulting in difficulty learning or comprehending arithmetic, such as difficulty in understanding numbers, learning how to manipulate numbers, performing mathematical calculations and learning facts in mathematics. It is sometimes informally known as "math dyslexia", though this can be misleading as dyslexia is a different condition from dyscalculia. Dyscalculia is associated with dysfunction in the region around the intraparietal sulcus and potentially also the frontal lobe. Dyscalculia does not reflect a general deficit in cognitive abilities or difficulties with time, measurement, and spatial reasoning. Estimates of the prevalence of dyscalculia range between 3 and 6% of the population. In 2015 it was established that 11% of children with dyscalculia also have ADHD. Dyscalculia has also been associated with Turner syndrome and people who have spina bifida. Mathematical disabilities can occur as the result of some types of brain injury, in which case the term acalculia is used instead of dyscalculia which is of innate, genetic or developmental origin.

Indication
In medicine, an indication is a valid reason to use a certain test, medication, procedure, or surgery. There can be multiple indications to use a procedure or medication. An indication can commonly be confused with the term diagnosis. A diagnosis is the assessment that a particular [medical] condition is present while an indication is a reason for use. The opposite of an indication is a contraindication, a reason to withhold a certain medical treatment because the risks of treatment clearly outweigh the benefits. In the United States, indications for prescription drugs are approved by the FDA. Indications are included in the Indications and Usage section of the Prescribing Information. The primary role of this section of labeling is to enable health care practitioners to readily identify appropriate therapies for patients by clearly communicating the drug’s approved indication(s). The Indications and Usage section states the disease or condition, or manifestation or symptoms thereof, for which the drug is approved, as well as whether the drug is indicated for the treatment, prevention, mitigation, cure, relief, or diagnosis of that disease or condition. Additionally, the Indications and Usage section should contain the approved age groups as well as other information necessary to describe appropriate use (e.g., identifying the indicated patient/disease subgroups, stating if adjunctive therapy is required).

Mechanisms of Antibiotic Resistance
Bacteria can exhibit two types of antibiotic resistance: intrinsic and acquired. While intrinsic resistance is determined by naturally occurring mechanisms conferred by inherent structural and/or functional features of the bacteria, the acquired resistance results from the changes in the bacterial genome. These consist of mutations in antibiotic-targeted genes or the acquisition of exogenous DNA conferring resistance, horizontally transferred by plasmids, bacteriophages, transposons, or other mobile genetic elements. Many independent mechanisms of bacterial resistance to antibiotics have been identified, including primarily modification of the antibiotic target, changes in the cell envelope’s permeability, active pumping of the antibiotic out of the cell (so-called efflux system), and enzymatic inactivation.

The Importance of Capsules in Dry Powder Inhalers
Capsule-based dry powder inhalers (cDPI) use a hard capsule that contains a powder formulation which consists of a mixture of a micronized drug and a carrier usually the lactose, known for its good lung tolerance. The capsule is either inserted into the device during manufacturer or by the patient prior to use. After perforating, opening or cut the capsule in the device, patients take a deep and rapid breath to inhale the powder, using air as the vector of drug displacement. The system is simple, relatively cheap and characterized by a lower carbon footprint than that of pressurized metered dose inhalers.
