Reconnaissance Satellite
A reconnaissance satellite or intelligence satellite (commonly, although unofficially, referred to as a spy satellite) is an Earth observation satellite or communications satellite deployed for military or intelligence applications. The first generation type (i.e., Corona and Zenit) took photographs, then ejected canisters of photographic film which would descend back down into Earth's atmosphere. Corona capsules were retrieved in mid-air as they floated down on parachutes. Later, spacecraft had digital imaging systems and downloaded the images via encrypted radio links. In the United States, most information available is on programs that existed up to 1972, as this information has been declassified due to its age. Some information about programs prior to that time is still classified, and a small amount of information is available on subsequent missions. A few up-to-date reconnaissance satellite images have been declassified on occasion, or leaked, as in the case of KH-11 photographs which were sent to Jane's Defence Weekly in 1984.

EntreComp Questionnaire for Entrepreneurship Competencies
The European Entrepreneurship Competence Framework (EntreComp) offers a comprehensive description of the knowledge, skills, and attitudes that people need to develop for an entrepreneurial mindset. Entrepreneurship competencies have usually been equated to management skills, but it is assumed that entrepreneurship activities cannot be narrowed to the management of business, since it requires a wider range of competencies. In particular, the European Council adopted the concept of entrepreneurship competencies as a set of abilities with the potential of shaping society through value creation at a social, cultural, or financial level with the sense of entrepreneurship as one of the eight key competencies necessary for a knowledge-based society.

Extracellular Calcium and Inflammation
Burn injury serves as an example of a condition with a robust systemic inflammatory response. The elevation of circulating interleukins (IL)-1β and -6 in children and adolescents with severe burn injury upregulates the parathyroid calcium-sensing receptor (CaSR), resulting in hypocalcemic hypoparathyroidism accompanied by urinary calcium wasting. This effect protects the body from the hypercalcemia that results from bone resorption, liberating calcium into the circulation. Extracellular calcium can exacerbate and prolong the inflammatory response by stimulating mononuclear cell chemokine production as well as the NLRP3 inflammasome of the innate immune system, resulting in increased IL-1 production by monocytes and macrophages. Interestingly, the CaSR upregulation in response to inflammatory cytokines disappears with age, potentially trapping calcium from bone resorption in the circulation, allowing it to contribute to increased inflammation and possibly increased calcium deposition in small arteries, such as the coronaries, as conditions with increased chronic inflammation, such as spinal cord injury, osteoarthritis, and rheumatoid arthritis have an incidence of cardiovascular disease and coronary artery calcium deposition significantly higher than the unaffected age-matched population.

Theosophy and Music
According to some musicology and religious studies scholars, after the foundation of the Theosophical Society (1875), some professional musicians had a fancy for Theosophy, at the same time, the Theosophists had often engaged in music. However, several composers like Alexander Scriabin, Cyril Scott, Luigi Russolo chose Theosophy as the main ideological and philosophical basis of their work. Prof. Julia Shabanova stated that music, having both "existential and metaphysical" traits, extends comprehension of the world to its "universal constants". The European thought of the 19th century, which was in the period of the emergence of modern Theosophy in the process of "changing the philosophical and worldview paradigms", needed this.

Intestinal Stem Cells
Intestinal stem cells (ISC) are crucial players in colon epithelium physiology. The accurate control of their auto-renewal, proliferation and differentiation capacities provides a constant flow of regeneration, maintaining the epithelial intestinal barrier integrity. Under stress conditions, colon epithelium homeostasis in disrupted, evolving towards pathologies such as inflammatory bowel diseases or colorectal cancer. A specific environment, namely the ISC niche constituted by the surrounding mesenchymal stem cells, the factors they secrete and the extracellular matrix (ECM), tightly controls ISC homeostasis. Colon ECM controls ISC homeostasis by exerting physical constraint on the enclosed stem cells through peculiar topography, stiffness and deformability.

Hydrogen Production in Arctic Region
The development of markets for low-carbon energy sources requires reconsideration of issues related to extraction and use of oil and gas. Significant reserves of hydrocarbons are concentrated in Arctic territories, e.g., 30% of the world’s undiscovered natural gas reserves and 13% of oil. Associated petroleum gas, natural gas and gas condensate could be able to expand the scope of their applications. Natural gas is the main raw material for the production of hydrogen and ammonia, which are considered promising primary energy resources of the future, the oxidation of which does not release CO2. Complex components contained in associated petroleum gas and gas condensate are valuable chemical raw materials to be used in a wide range of applications.

Carbonation and Its Mechanisms in Reinforced Concrete Structures
Reinforced concrete (RC) has been commonly used as a construction material for decades due to its high compressive strength and moderate tensile strength. However, these two properties of RC are frequently hampered by degradation. The main degradation processes in RC structures are carbonation and the corrosion of rebars. The scientific community is divided regarding the process by which carbonation causes structural damage. Some researchers suggest that carbonation weakens a structure and makes it prone to rebar corrosion, while others suggest that carbonation does not damage structures enough to cause rebar corrosion.

Apocalypse
Apocalypse (from grc ἀποκάλυψις (apokálupsis) 'revelation, disclosure') is a literary genre in which a supernatural being reveals cosmic mysteries or the future to a human intermediary. The means of mediation include dreams, visions and heavenly journeys, and they typically feature symbolic imagery drawn from the Hebrew Bible, cosmological and (pessimistic) historical surveys, the division of time into periods, esoteric numerology, and claims of ecstasy and inspiration. Almost all are written under pseudonyms (false names), claiming as author a venerated hero from previous centuries, as with Book of Daniel, composed during the 2nd century BCE but bearing the name of the legendary Daniel. Eschatology, from Greek eschatos, last, concerns expectations of the end of the present age, and apocalyptic eschatology is the application of the apocalyptic world-view to the end of the world, when God will punish the wicked and reward the faithful. An apocalypse will often contain much eschatological material, but need not: the baptism of Jesus in Matthew's gospel, for example, can be considered apocalyptic in that the heavens open for the presence of a divine mediator (the dove representing the spirit of God) and a voice communicates supernatural information, but there is no eschatological element. Scholars have identified examples of the genre ranging from the mid-2nd century BCE to the 2nd century CE, and examples are to be found in Persian and Greco-Roman literature as well as Jewish and Christian. The sole clear case in the Jewish Bible (Old Testament) is chapters 7-12 of the Book of Daniel, but there are many examples from non-canonical Jewish works; the Book of Revelation is the only apocalypse in the New Testament, but passages reflecting the genre are to be found in the gospels and in nearly all the genuine Pauline epistles.Lua error: not enough memory.Lua error: not enough memory.
