Hiranyakashipu
Hiranyakashipu (Sanskrit: हिरण्यकशिपु, "clothed in gold"; the name is said to depict one who is very much fond of wealth: hiranya "gold," kashipu "soft cushion") is an Asura from the Puranic scriptures of Hinduism. Hiranyakashipu's Younger Brother, Hiranyaksha was slain by Varaha, one of the Avatars of Vishnu. Angered by this, Hiranyakashipu decided to gain magical powers by performing a penance for Lord Brahma. He was subsequently killed by the Narasimha Avatara of Lord Vishnu. His tale depicts the futility of desiring power over others and the strength of God's protection over his fully surrendered devotees (in the case of his son Prahlada). Hiranyakashipu, according to legend, was the king of the daityas and had earned a boon from Brahma that made him virtually indestructible. He grew arrogant, thought he was God, and demanded that everyone worship only him. The story of Hiranyakashipu is in three parts. The first has to do with the curse of the Four Kumaras on the gatekeepers of Vaikuntha, Jaya and Vijaya, which causes them to be born as the daityas Hiranyakashipu and Hiranyaksha. The second part deals with Hiranyakashipu's penance to propitiate Brahma and gain a boon from him. The final part deals with his efforts to kill his son Prahlada (a devotee of Vishnu) and his subsequent death at the hands of Narasimha.

Protection Motivation Theory
Protection motivation theory (PMT) was originally created to help understand individual human responses to fear appeals. Protection motivation theory proposes that people protect themselves based on two factors: threat appraisal and coping appraisal. Threat appraisal assesses the severity of the situation and examines how serious the situation is, while coping appraisal is how one responds to the situation. Threat appraisal consists of the perceived severity of a threatening event and the perceived probability of the occurrence, or vulnerability. Coping appraisal consists of perceived response efficacy, or an individual's expectation that carrying out the recommended action will remove the threat, and perceived self efficacy, or the belief in one's ability to execute the recommended courses of action successfully. PMT is one model that explains why people engage in unhealthy practices and offers suggestions for changing those behaviors. It is educational and motivational. Primary prevention: taking measures to combat the risk of developing a health problem. (e.g., controlling weight to prevent high blood pressure). Secondary prevention: taking steps to prevent a condition from becoming worse. (e.g., remembering to take daily medication to control blood pressure). Another psychological model that describes self-preservation and processing of fear is terror management theory.

Types of Adsorbents
There are two types of adsorbents, namely, natural and synthetic adsorbents. Several examples of natural adsorbents include clay and zeolite (abundant and cheap). On the other hand, researchers can produce synthetic adsorbents (activated carbon) via agricultural waste, industrial waste, and household waste.

Occupational Stress
Occupational stress is psychological stress related to one's job. Occupational stress refers to a chronic condition. Occupational stress can be managed by understanding what the stressful conditions at work are and taking steps to remediate those conditions. Occupational stress can occur when workers do not feel supported by supervisors or coworkers, feel as if they have little control over the work they perform, or find that their efforts on the job are incommensurate with the job's rewards. Occupational stress is a concern for both employees and employers because stressful job conditions are related to employees' emotional well-being, physical health, and job performance. A landmark study conducted by the World Health Organization and the International Labour Organization found that exposure to long working hours, which are theorized to operate through increased psycho-social occupational stress, is the occupational risk factor with the largest attributable burden of disease, according to these official estimates causing an estimated 745,000 workers to die from ischemic heart disease and stroke events in 2016. A number of disciplines within psychology are concerned with occupational stress including occupational health psychology, human factors and ergonomics, epidemiology, occupational medicine, sociology, industrial and organizational psychology, and industrial engineering.

Labia
The labia are part of the female genitalia; they are the major externally visible portions of the vulva. In humans, there are two pairs of labia: the labia majora (or the outer labia) are larger and fattier, while the labia minora are folds of skin between the outer labia. The labia surround and protect the clitoris and the openings of the vagina and the urethra.

Ground-Penetrating Radar in Soil Studies
Information on the spatiotemporal variability of soil properties and states within the agricultural landscape is vital to identify management zones supporting precision agriculture (PA). Ground-penetrating radar (GPR) and electromagnetic induction (EMI) techniques have been applied to assess soil properties, states, processes, and their spatiotemporal variability.

COVID-19
Researchers present an overview of the current state of knowledge on the SARS-CoV-2 and COVID-19 pandemic. In addition to an overview of the epidemiological, clinical, and radiological features of SARS-CoV-2, researchers also summarize possible therapeutic options currently under investigation and the future outlook for the disease. Whereas the trials on SARS-CoV-2 genome-based specific vaccines and therapeutic antibodies are currently being tested, this solution is more long-term, as they require thorough testing of their safety. On the other hand, the repurposing of the existing therapeutic agents previously designed for other virus infections and pathologies happens to be the only practical approach as a rapid response measure to the emergent pandemic. The current pandemic emergency will be a trigger for more systematic drug repurposing design approaches based on big data analysis. Further on, regression analytical review is presented on the virological and evolutionary history of SARS-CoV viruses, indicating to the autoimmune pathogen.
