Informal Sector Employment and Economic Growth
Originating in the context of third-world countries, the informal sector constitutes a dominant part of the economy and is identified as an untapped reservoir of opportunities in terms of employment and the entrepreneurial capabilities of developing countries; it is often called the subordinate zone of the overall economy that can play a significant role in the growth and socio-economic development of countries across the world. The informal sector accounts for almost half of the economic activities in developing countries. These activities were initially backed by the core assumptions of the classical theory that the informal economy would wither away after achieving persistent growth. However, the new view of the informal economy features it as contemporary growth that should proceed as a result of the changed economic context of countries. The prevalent feature of the informal economy around the globe provides support to the new view of informality, mentioned as a dichotomist’s approach, which indicates that the informal economy will not wither away; rather, it will be contested in an arrangement of interdependent coexistence with distinctively different conditions, notably in terms of employment arrangements.

Linguistics in Science Fiction
Linguistics has an intrinsic connection to Science Fiction stories given the nature of science fiction. As mentioned in Aliens and Linguists: Language Study and Science Fiction by Walter E. Meyers, science fiction is almost always concerned with the idea of communication, such as communication with aliens and machines, or communication using dead languages and evolved languages of the future. Authors of science fiction at times use Linguistics and Linguistic theories as a tool for storytelling, although technical terms are rarely used with authors only going into as much detail as the reader will understand. While Linguistics can be found to be employed by writers of science fiction, it must be noted that not all uses are accurate to actual Linguistics and Linguistic Theories. Nevertheless, there still exists the lingering presence and use of Linguistics (even if inaccurate) in such cases. As mentioned by Walter E. Meyers, the ability to make a story seem more unfamiliar and exotic, and an alien seem less of a costumed human who merely differs in physical appearance, is only possible through the use of language. It is this ability that appears to draw the boundary between great works of science fiction and those lesser so. As such, Linguistics, the scientific study of language, comes to hold an important role in the genre of science fiction.

Therizinosaur
Therizinosaurs (or segnosaurs) were theropod dinosaurs belonging to the clade Therizinosauria. Therizinosaur fossils have been found in Early through Late Cretaceous deposits in Mongolia, the China and western North America. Various features of the forelimbs, skull and pelvis unite these finds as both theropods and as maniraptorans, close relatives to birds. The name therizinosaur is derived from the Greek θερίζω therízein, meaning 'to reap' or 'to cut off', and σαῦρος saûros meaning 'lizard'. The older name segnosaur is derived from Latin segnis meaning 'slow' or 'sluggish', and Greek σαυρος, sauros, meaning 'lizard'.

Doxorubicin
The antibiotic doxorubicin is often used as an anti-neoplastic drug; however, many patients showed very unpleasant side-effects. Previous studies have demonstrated that dietary substances such as Aloe arborescens, Annona muricata, Morinda citrifolia, Beta rubra, Scutellaria baicalensis, and Vaccinium myrtillus may have anti-oxidant, anti-proliferative, and anti-inflammatory effects. The purpose of this study was to investigate the protective effects of a mixture of these components in an experimental model of doxorubicin toxicity. Rats (n = 30) received doxorubicin (5 mg/kg/day) for 4 weeks and were randomized to receive the dietary mixture 2 hours following the first doxorubicin injection and until the end of the experiment. Animals were killed following 4 weeks, and blood, liver, and heart were collected for further analysis. The dietary supplement improved the depressed body weight and food consumption induced by DOX. In addition, the nutraceutical mixture reduced oxidative stress, ameliorated the morphological score, and preserved liver and heart structure, demonstrating a protective effect. These data show for the first time that the mixture of Aloe arborescens, Annona muricata, Morinda citrifolia, Beta rubra, Scutellaria baicalensis, and Vaccinium myrtillus may be useful to reduce the side effects following treatment with doxorubicin, and might ameliorate the quality of life of patients following chemotherapy.

The Role of Identity in Eating Behaviors
Identity is a major construct in the fields of psychology and anthropology that can relate to both the maintenance of eating behaviors and cultural sensitivity. Social and self-identities, as well as ethnic, religious, ethical, eater-type, and other behavior-based identities, are associated with eating behavior change and maintenance.  Identity measurements greatly vary in type and complexity, but the most robust include some accounting for multiple identities and identity shifting over time. Multiple aspects of identity reciprocally reinforce eating behaviors, and change maintenance is associated with identity salience and identity centrality. Identity is an important way to understand the internal landscape of individuals and may be underutilized and heterogeneously applied in eating behavior research. The inclusion of identity assessments seems to lead to better outcomes and increased predictive and explanatory power regarding eating behaviors and can be especially meaningful within differing cultural, normative, and environmental scenarios.

Extra (Acting)
A background actor or extra is a performer in a film, television show, stage, musical, opera or ballet production, who appears in a nonspeaking or nonsinging (silent) capacity, usually in the background (for example, in an audience or busy street scene). War films and epic films often employ background actors in large numbers: some films have featured hundreds or even thousands of paid background actors as cast members (hence the term "cast of thousands"). Likewise, grand opera can involve many background actors appearing in spectacular productions. On a film or TV set, background actors are usually referred to as "junior artist", "atmosphere", "background talent", "background performers", "background artists", "background cast members" or simply "background", while the term "extra" is rarely used. In a stage production, background actors are commonly referred to as "supernumeraries". In opera and ballet, they are called either "extras" or "supers".

Fluid Resuscitation in Sepsis
The importance of fluid resuscitation therapy during the early stages of sepsis management is a well-established principle. Current Surviving Sepsis Campaign (SSC) guidelines recommend the early administration of intravenous crystalloid fluids for sepsis-related hypotension or hyperlactatemia due to tissue hypoperfusion, within the first 3 h of resuscitation and suggest using balanced solutions (BSs) instead of normal saline (NS) for the management of patients with sepsis or septic shock.

Molybdenum Tailings in Concrete Manufacturing
Dealingwithmineral tailings is one of themost important topics for solving the environmental problems in the mining industry. Among the techniques converting stacked molybdenum tailings to reusable cleaner products, one of the most effective ones is to use molybdenum tailings in concrete productions. The physical properties including density, microscopic structure and finesse module, and chemical composition of molybdenum tailings are similar with those of natural sand. The radionuclide assessment of molybdenum tailing meets the requirements for using as structural materials. Therefore, Molybdenum tailing is suitable to be used as the replacement of cement and fine aggregates in mortarand concrete. Based on the results of strength and duration performance comparison, the usage of molybdenum tailing as a replacement of natural sand is a more feasible way than that of ground super-fine molybdenum tailings in cement binder. It is feasible to use molybdenum tailings as fine aggregate in the preparation of structural concrete. When the amount of ground super-finemolybdenum tailings replacing cement is less than 10%, it is beneficial to improve the freeze-thaw and carbonization resistance of the concrete.

Treatment of Inflammatory Bowel Disease
Inflammatory bowel disease (IBD) represents an umbrella term for the chronic remission and relapse of immunologically-mediated idiopathic diseases. IBD is generally diagnosed under two major classifications as Crohn’s disease (CD) and ulcerative colitis (UC) with significantly contrasting etiologies. Multiple studies over the decades have still remarkably left the pathogenesis of the diseases an unresolved mystery. CD tends to occur in any part of the gastrointestinal tract (GIT) and is associated with complications, whereas UC, on the other hand, is strictly restricted to the inflammation of the colon. The onset of the diseases is marked at young adulthood in genetically susceptible individuals responding to commensal microbes or environmental cues like poor hygiene, unbalanced dietary intake, a lack of physical exercise, smoking, and stress.

Peroxisomal Stress Response and Inter-Organelle Communication
Peroxisomes are single membrane-bound organelles found in all eukaryotic cells and organisms, from yeast to plants and mammals. They are key regulators of cellular and metabolic homeostasis. These organelles play important roles in redox metabolism, the oxidation of very-long-chain fatty acids (VLCFAs), and the biosynthesis of ether phospholipids. Given the essential role of peroxisomes in cellular homeostasis, peroxisomal dysfunction has been linked to various pathological conditions, tissue functional decline, and aging. In the past few decades, a variety of cellular signaling and metabolic changes have been reported to be associated with defective peroxisomes, suggesting that many cellular processes and functions depend on peroxisomes. Peroxisomes communicate with other subcellular organelles, such as the nucleus, mitochondria, endoplasmic reticulum (ER), and lysosomes. These inter-organelle communications are highly linked to the key mechanisms by which cells surveil defective peroxisomes and mount adaptive responses to protect them from damages.

Respirator Cartridge
A respirator cartridge or canister is a container that cleans pollution from air. People working in polluted atmospheres use respirators for health preservation. If the air in the workplace is polluted with noxious gases, but contains sufficient oxygen (>19.5% in US; >18% in RF) they often use air-purifying respirators (APR). These respirators provide users breathable air by removing pollution from ambient air using canisters or cartridges. There are cartridges of different types, and they must be chosen correctly and replaced in a timely manner.
