Electrical Transcription
Electrical transcriptions are special phonograph recordings made exclusively for radio broadcasting, which were widely used during the 'Golden Age of Radio', wherein, they provided material—from station-identification jingles and commercials to full-length programs—for use by local stations, affiliates of one of the radio networks. Physically, electrical transcriptions look much like long-playing records that were popular for decades. They differ from consumer-oriented recordings, however, in that they were "distributed to radio stations for the purpose of broadcast, and not for sale to the public.... The ET had higher quality audio than was available on consumer records" largely because they had less surface noise than commercial recordings,

Neo-Advaita
Neo-Advaita, also called the Satsang-movement and Nondualism, is a New Religious Movement, emphasizing the direct recognition of the non-existence of the "I" or "ego," without the need of preparatory practice. Its teachings are derived from, but not authorised by, the teachings of the 20th century sage Ramana Maharshi, as interpreted and popularized by H. W. L. Poonja and several of his western students. It is part of a larger religious current called immediatism by Arthur Versluis, which has its roots in both western and eastern spirituality. Western influences are western esoteric traditions like Transcendentalism, and "New Age millennialism, self-empowerment and self-therapy". Neo-Advaita makes little use of the "traditional language or cultural frames of Advaita Vedanta", and some have criticised it for its lack of preparatory training, and regard enlightenment-experiences induced by Neo-Advaita as superficial.

Premature Ovarian Insufficiency and Infertility
Reproductive aging is on the rise globally and inseparable from the entire aging process. An extreme form of reproductive aging is premature ovarian insufficiency (POI), which to date has mostly been of idiopathic etiology, thus hampering further clinical applications and associated with enormous socioeconomic and personal costs. In the field of reproduction, timely diagnosis with a clear understanding of the various comorbidities that can arise from estrogen deficiency and the important functional role of inflammation-induced ovarian deterioration are research hotspots for appropriate counseling and preventing this prematurely ovarian aging disease. It is evident that more research is required to allow pre-emptive identification of the at-risk population and to identify mechanisms that, if addressed promptly, can prolong ovarian function and fertility.

Disinformation Perception by Digital and Social Audiences: Threat Awareness, Decision-Making and Trust in Media Organizations
The effects of disinformation in the media and social networks have been extensively studied from the perspective of reception studies. However, the perception of this media phenomenon expressed by different types of audiences in distant geographic locations and with different media cultures has hardly been addressed by experts. This theoretical review study aims to analyze the relationship between the actual level of disinformation and the perception expressed by the audiences themselves. The results of the study reveal, firstly, that users of social networks and digital media do not perceive being surrounded by an excessively worrying volume of disinformation, a fact that contrasts with the data recorded, which are visibly higher. This situation reveals that the audience tends to normalize disinformation, which is intensively consumed on a daily basis and does not seem to worry the public in general terms, although some differences can be detected depending on variables such as gender, age or education. On the other hand, paradoxically, audiences visibly express rejection attitudes towards the channels that disseminate false information, with media outlets being the least trusted, despite recognizing that social networks are the place where more disinformation is generated and circulated at the same time.

Mad Pride
Mad Pride is a mass movement of the users of mental health services, former users, and the aligned, and that individuals with mental illness should be proud of their 'mad' identity. It was formed in 1993 in response to local community prejudices towards people with a psychiatric history living in boarding homes in the Parkdale area of Toronto, Ontario, Canada, and an event has been held every year since then in the city except for 1996. A similar movement began around the same time in the United Kingdom. By the late 1990s similar events were being organized under the Mad Pride name around the globe, including Australia, Ireland, Portugal, Brazil, Madagascar, South Africa and the United States. Events draw thousands of participants, according to MindFreedom International, a United States mental health advocacy organization that promotes and tracks events spawned by the movement. Mad Pride activists seek to reclaim terms such as "mad", "nutter", and "psycho" from misuse, such as in tabloid newspapers and in order to switch it from a negative message into a positive one. Through a series of mass media campaigns, Mad Pride activists seek to re-educate the general public on such subjects as the causes of mental disabilities, the experiences of those using the mental health system, and the global suicide pandemic. One of Mad Pride's founding activists in the UK was Pete Shaughnessy, who later died by suicide. Mark Roberts, Robert Dellar (who died in 2016) and Simon Barnet were among the other founders of the movement. Mad Pride: A celebration of mad culture records the early Mad Pride movement. On Our Own: Patient-Controlled Alternatives to the Mental Health System, published in 1978 by Judi Chamberlin, is a foundational text in the Mad Pride movement, although it was published before the movement was launched. The first known event, specifically organized as a Pride event by people who identified as survivors, consumers or ex-patients of psychiatric practices, was held on 18 September 1993, when it was called "Psychiatric Survivor Pride Day".

Hydrogen Bond Energy
Hydrogen bonds (HBs) play a crucial role in many physicochemical and biological processes. Theoretical methods can reliably estimate the intermolecular HB energies. Quantifying an intramolecular hydrogen bond (IHB) strength is not as straightforward as the intermolecular one. The main difficulty lies in isolating the X–H···Y interaction present within a molecule than in a dimer or a complex. However, the procedure discussed (viz. molecular tailoring approach) in this article, allows the generation of fragments so that the atoms/functional groups involved in the HB formation are parts of two different fragments. The energies of these fragments are added or substracted, using the inclusion exclusion principle in set theory, to obtained the energy of HB bond.

Visegrád Group
The Visegrád Group, Visegrád Four, or V4, is a cultural and political alliance of four Central European countries – the Czech Republic, Hungary, Poland and Slovakia, that are members of the European Union (EU) and NATO – for the purposes of advancing military, cultural, economic and energy cooperation with one another along with furthering their integration in the EU. The Group traces its origins to the summit meetings of leaders from Czechoslovakia, Hungary, and Poland held in the Hungarian castle-town of Visegrád on 15 February 1991. Visegrád was chosen as the location for the 1991 meeting as an intentional allusion to the medieval Congress of Visegrád in 1335 between John I of Bohemia, Charles I of Hungary and Casimir III of Poland. After the dissolution of Czechoslovakia in 1993, the Czech Republic and Slovakia became independent members of the group, thus increasing the number of members from three to four. All four members of the Visegrád Group joined the European Union on 1 May 2004.

Solar Radiation Management
Solar radiation management (SRM) proposals are a type of climate engineering which would seek to reflect sunlight and thus reduce global warming. Proposed methods include increasing the planetary albedo, for example using stratospheric sulfate aerosols. Restorative methods have been proposed regarding the protection of natural heat reflectors like sea ice, snow and glaciers with engineering projects. Their principal advantages as an approach to climate engineering is the speed with which they can be deployed and become fully active, their potential low financial cost, and the reversibility of their direct climatic effects. Solar radiation management projects could serve as a temporary response while levels of greenhouse gases can be brought under control by mitigation and greenhouse gas removal techniques. They would not reduce greenhouse gas concentrations in the atmosphere, and thus do not address problems such as ocean acidification caused by excess carbon dioxide (CO2).

Halitosis
Halitosis, also known as fetor ex ore, bad breath or oral malodor, is a common disorder meaning unpleasant smell from the mouth. Halitosis is a common problem that manifests as an unpleasant and disgusting odor emanating from the mouth[1]. Malodor is mainly caused by putrefactive actions of microorganisms on endogenous or exogenous proteins and peptides. Oral malodor is an embarrassing condition that affects a large percentage of the human population. This condition often results in nervousness, humiliation, and social difficulties, such as the inability to approach people and speak to them[2][3][4][5][6].

Hypopigmented mycosis fungoides
Hypopigmented mycosis fungoides (HMF) is a variant of cutaneous T-cell lymphoma (CTCL), a heterogeneous group of extranodal non-Hodgkin’s lymphomas. HMF and classic (erythematous patch/plaque) Mycosis Fungoides (MF) display contrasting clinical characteristics: (i) HMF presents with light colored to achromic patches, as opposed to classic MF, which presents with erythematous scaly patches, plaques, tumors or erythroderma, (ii) HMF primarily affects individuals with darker skin types (Fitzpatrick phototypes IV-VI), while classic MF affects mostly Caucasians, (iii) HMF is commonly seen in pediatric/adolescents and young adults, whereas classic MF is more prevalent in elderly individuals, and (iv) the predominant malignant cells in HMF are CD8+T-cells, as opposed to CD4+T-cells in classic MF. Our recent review paper highlights that active antitumor immune response, specifically a Th1/cytotoxic antitumor immune response seen robustly in HMF, is likely responsible for the differential behavior between these two MF variants. Furthermore, we propose that the hypopigmentation (clinical sign) may serve as a surrogate marker for the presence of antitumor immune response and may portend better prognosis.

Nanomaterials Combined with Bacteriocins
Bacteriocins are antimicrobial peptides or proteinaceous materials produced by bacteria against pathogens. These molecules have high efficiency and specificity and are equipped with many properties useful in food-related applications, such as food preservatives and additives, as well as biomedical applications, such as serving as alternatives to current antibacterial, antiviral, anti-cancer, and antibiofilm agents. Despite their advantages as alternative therapeutics over existing strategies, several limitations of bacteriocins, such as the high cost of isolation and purification, narrow spectrum of activity, low stability and solubility, and easy enzymatic degradation, need to be improved. Nanomaterials are promising agents in many biological applications. They are widely used in the conjugation or decoration of bacteriocins to augment the activity of bacterioc-ins or reduce problems related to their use in biomedical applications. Therefore, bacteriocins combined with nanomaterials have emerged as promising molecules that can be used in various biomedical applications.

The Proteasome System
The proteasome system is a large and complex molecular machinery responsible for the degradation of misfolded, damaged, and redundant cellular proteins. When proteasome function is impaired, unwanted proteins accumulate, which can lead to several diseases including age-related and neurodegenerative diseases. Enhancing proteasome-mediated substrate degradation with small molecules may therefore be a valuable strategy for the treatment of various neurodegenerative diseases such as Parkinson’s, Alzheimer’s, and Huntington’s diseases.

Human Resources Churning
The term churning is defined by a multifaceted approach and is quite a complex concept that has been gaining relevance in the field of human resources, due to the problematic loss of investment, originating from the voluntary exits of worker-associated costs. This phenomenon is a direct result of the rising competitive job market, causing employees to leave organizations and carry with them all the knowledge and experience acquired in the starting organization, an organization which invested in the development of its workers. Even though churning is aligned with human resource practices, it is considered a multifaceted concept because of the different contexts in which it interferes, such as economic context, per activity sector, clients, the type of organization, geographic location, etc. Although, despite its own complexity, churning is related to turnover; however, there are differences between these two concepts. While turnover is linked to the workers’ rotation within an organization, churning is mainly focused on the costs associated with voluntary exits from workers. It is simply linked to investment losses inside an organization, which has the main goal of creating mechanisms that allow the creation of awareness in organizations about the relevancy of action using strategic measurements of holding in order to minimize the churning rate, and in this way, reducing the unexpected costs, creating revenue, increasing proficiency, standing out in business activity, bettering nimbleness and expanding profits. This initial manuscript introduces the churning concept in human resources, the main causes of churning, as well as approaching how organizations take action in order to appease this event using literature, which lacks major advertising and given relevance to its pertinence in human resources. Through the analysis of the existing, this entry was guided with the objective of demystifying the subject of human resource churning.

Nitrogen, Phosphorus and Microalgal
Microalgae can be used as a source of alternative food, animal feed, biofuel, fertilizer, cosmetics, nutraceuticals and for pharmaceutical purposes. The extraction of organic constituents from microalgae cultivated in the different nutrient compositions is influenced by microalgal growth rates, biomass yield and nutritional content in terms of lipid and fatty acid production. In this context, nutrient composition plays an important role in microalgae cultivation, and depletion and excessive sources of this nutrient might affect the quality of biomass. Investigation on the role of nitrogen and phosphorus, which are crucial for the growth of algae, has been addressed. However, there are challenges for enhancing nutrient utilization efficiently for large scale microalgae cultivation. Hence, this study aims to highlight the level of nitrogen and phosphorus required for microalgae cultivation and focuses on the benefits of nitrogen and phosphorus for increasing biomass productivity of microalgae for improved lipid and fatty acid quantities. Furthermore, the suitable extraction methods that can be used to utilize lipid and fatty acids from microalgae for biofuel have also been reviewed.
