Control Freak
In the slang of psychology, the colloquial term control freak describes a person with a personality disorder characterized by undermining other people, usually by way of controlling behavior manifested in the ways that they act to dictate the order of things in a social situation. The term control freak was first used in the 1970s, a decade when the cultural Zeitgeist featured liberal social norms, which espoused the live-and-let-live principle of "Do your own thing" in opposition to the perceived requirement of social conformity within traditional conservatism.

M79 Grenade Launcher
The M79 grenade launcher is a single-shot, shoulder-fired, break-action grenade launcher that fires a 40×46mm grenade, which uses what the US Army calls the High-Low Propulsion System to keep recoil forces low, and first appeared during the Vietnam War. Because of its distinctive report, it has earned the nicknames of "Thumper", "Thump-Gun", "Bloop Tube", "Big Ed", and "Blooper" among American soldiers as well as "Can Cannon" in reference to the grenade size; Australian units referred to it as the "Wombat Gun". The M79 can fire a wide variety of 40 mm rounds, including explosive, anti-personnel, smoke, buckshot, flechette (pointed steel projectiles with a vaned tail for stable flight), and illumination. While largely replaced by the M203, the M79 has remained in service in many units worldwide in niche roles.

Nutritional Deficiencies Associated with Obesity
Obesity is a critical medical condition worldwide that is increasingly involved with nutritional derangements associated with micronutrient deficiencies, including iron, zinc, calcium, magnesium, selenium, and vitamins A, C, D, and E. Nutritional deficiencies in obesity are mainly caused by poor-quality diets, higher nutrient requirements, alterations in micronutrient metabolism, and invasive obesity treatments. The current conventional agricultural system is designed for intensive food production, focusing on food quantity rather than food quality, consuming excessive agricultural inputs, and producing nutrient-deficient foods, thus generating severe health and environmental problems; agricultural food products may worsen obesity-related malnutrition. Therefore, modern agriculture is adopting new biofortification technologies to combat micronutrient deficiencies and improve agricultural productivity and sustainability.

Master–Slave Dialectic
The master–slave dialectic is the common name for a famous passage of Georg Wilhelm Friedrich Hegel's Phenomenology of Spirit, though the original German phrase, Herrschaft und Knechtschaft, is more properly translated as Lordship and Bondage. It is widely considered a key element in Hegel's philosophical system, and has heavily influenced many subsequent philosophers. The passage describes, in narrative form, the development of self-consciousness as such in an encounter between what are thereby (i.e., emerging only from this encounter) two distinct, self-conscious beings. The essence of the dialectic is the movement or motion of recognizing, in which the two self-consciousnesses are constituted in being each recognized as self-conscious by the other. This movement, inexorably taken to its extreme, takes the form of a "struggle to the death" in which one masters the other, only to find that such lordship makes the very recognition he had sought impossible, since the bondsman, in this state, is not free to offer it.

Seaport
Seaports are well known as the medium that has evolved into the central link between sea and land for complex marine activities. The growth in maritime logistics particularly necessitates a large volume of energy supply in order to maintain the operation of sea trade, resulting in an imbalance between generation and demand sides. Future projections for three major concerns show an increase in load demand, cost of operation, and environmental issues. The involvement of a variety of heavy loads such as all-electric ships, cranes, cold ironing, and buildings infrastructure renders it a complicated arrangement task in several aspects, which necessitates further research and leaves space for improvement.

Collagen
Collagen is the major fibrillar protein in most living organisms. Among the different types of collagen, type I collagen is the most abundant one in the tissues of marine invertebrates. The present overview has focused on a brief history of collagen, basic structure and synthesis, nomenclature, types, and classifications, sources of collagen with the emphasis on sea cucumber collagen, and related functional properties.

List of Socialist States
Several past and present states have declared themselves socialist states or in the process of building socialism. The majority of self-declared socialist countries have been Marxist–Leninist or inspired by it, following the model of the Soviet Union or some form of people's or national democracy. They share a common definition of socialism and they refer to themselves as socialist states on the road to communism with a leading vanguard party structure, hence they are often called communist states. Meanwhile, the countries in the non-Marxist–Leninist category represent a wide variety of different interpretations of the term socialism and in many cases the countries do not define what they mean by it. Modern uses of the term socialism are wide in meaning and interpretation. Because a sovereign state is a different entity from the political party that rules that state at any given time, a country may be ruled by a socialist party without the country itself claiming to be socialist or the socialist party being written into the constitution. This has occurred in both one-party and multi-party political systems. In particular, there are numerous cases of social democratic and democratic socialist parties winning elections in liberal democratic states and ruling for a number of terms until a different party wins the elections. While socialist parties have won many elections around the world and most elections in the Nordic countries, many of those countries have not adopted socialism as a state ideology or written the party into the constitution. Several countries with liberal democratic constitutions mention socialism. India is a liberal democracy that has been ruled by non-socialist parties on many occasions, but its constitution makes references to socialism. Certain other countries such as Croatia, Hungary, Myanmar, and Poland have constitutions that make references to their communist and socialist past by recognizing or condemning it, but without claiming to be socialist in the present.

Bias Temperature Instability of MOSFETs
CMOS technology dominates the semiconductor industry, and the reliability of MOSFETs is a key issue. Negative bias temperature instability (NBTI) and positive bias temperature instability (PBTI) mainly degrade the performance of pMOSFETs and nMOSFETs, respectively.
