Animal Foods' Lactic Acid Bacteria
A variety of lactic acid bacteria (LAB) strains, which are either part of the autochthonous microbiota or introduced into animal products, have potential beneficial applications for the preservation of such products and/or for consumer health. Many foods obtained from fermented products of animal origin, such as meat, fish, and dairy, contain living microorganisms that are phylogenetically similar to probiotic LAB as part of the microbiota that directs their fermentation process and is responsible for their unique character. Fermented foods, such as cultured milk, yogurt, cheese, fermented sausage, and certain types of wine, are obtained through enzymatic reactions resulting from controlled microbial growth, in which the main microbial effectors comprise, primarily, LAB and their metabolites.

Jewish Views on Marriage
The Jewish view on marriage, historically, provided Biblically mandated rights to the wife which were accepted by the husband. A marriage was ended either because of a divorce document given by the man to his wife, or by the death of either party. Certain details, primarily as protections for the wife, were added in Talmudic times. Non-Orthodox developments have brought changes in who may marry whom. Intermarriage is not encouraged.

Hydrogen Bond
The hydrogen bond may be treated as a local stabilizing interaction that acts between the proton or the electron charge deficient region of hydrogen centre and the electron rich region that is related to one or more centres. This may be named as the two-sites hydrogen bond definition. However in numerous studies the A-H proton donating bond with the positively charged H-atom and the proton acceptor, say B, being the electron rich centre are taken into account. Thus so-called A-H∙∙∙B hydrogen bridges are often considered. In such a way the three-sites hydrogen bond definition may be proposed that the hydrogen bond is the A-H∙∙∙B local stabilizing system with the proton situated between two A and B electron rich sites, most often closer to one of them, forming the A-H covalent bond; both A and B may correspond to one or more atomic centres.

pH Responsive Polyurethane for Biomedical and Drug Delivery
pH-responsive polymers are polymers that respond to changes in environmental pH. They can be classified into: (A) polymers with ionizable moieties; and (B) polymers that contain acid-labile linkages. pH-responsive polyurethanes demonstrated good biological response and sustainability in biomedical applications and drug delivery. They have been used as controlled drug delivery systems for oral administration, intravaginal administration, and targeted drug delivery systems for chemotherapy treatment.

Paper-Based Sensors Application
Paper-based sensors are getting increasing attention for reliable indoor/outdoor onsite detection with non-expert operation due to low cost, portability, easy disposal, and high accuracy, as well as bulky reduced laboratory equipment. They have become powerful analysis tools in trace detection with ultra-low detection limits and extremely high accuracy, resulting in their great popularity in biological detection, environmental inspection, and other applications. However, the current paper-based sensors still encounter insufficiencies such as harsh storage, short shelf time, singleplex analyte detection, disability of holographic strain detection, and low reproducibility for direct detection of the actual sample without pretreatment. Efforts should be made to paper-based sensors with those concerns before their broad commercial application.

Affordances of Innovative Learning Environments
Emerging innovative learning environments (ILEs) are designed to enable a wider pedagogical repertoire than traditional classrooms. In order to transcend stereotypical understandings about how the physical environment in schools may afford teaching and learning activities, it is becoming increasingly recognised that both design and practice reconceptualisation is required for affordances of new learning environments to be effectively actualised in support of contemporary education.

Amino Acids, B Vitamins, and Choline and ASD
Autism spectrum disorder (ASD) is a developmental disorder of variable severity, characterized by difficulties in social interaction, communication, and restricted or repetitive patterns of thought and behavior. In 2018, the incidence of ASD was 2.4 times higher than estimated in 2000. Through examining plasma profiles, urine samples, and dietary intake, researchers found that low choline, abnormal amino acid, and low B vitamin levels were present in children with ASD compared to those without ASD.

Hsp70 and Hsp90
Hsp70, Hsp90, and their co-chaperones are crucial members of the proteostasis network that are able to recognize misfolded proteins, aberrant condensates and protein aggregates, triaging proteins for refolding or degradation. These members of the chaperome are considered major sentinels impeding the molecular processes that lead to cell damage in the course of degenerative proteinopathies. Indeed, Hsp70, Hsp90 and their co-chaperones are increasingly recognized as therapeutic targets for the development of treatments against prevalent protein misfolding diseases.

Keyboard Cat
Template:Infobox internet video Keyboard Cat is an Internet meme. It consists of a video from 1984 of a female cat called "Fatso" wearing a blue shirt and "playing" an upbeat rhythm on an electronic keyboard. The video was posted to YouTube under the title "charlie schmidt's cool cats" in June 2007. Schmidt later changed the title to "Charlie Schmidt's Keyboard Cat (THE ORIGINAL)". Fatso (who died in 1987) was owned (and manipulated in the video) by Charlie Schmidt of Spokane, Washington, United States . Later, Brad O'Farrell, who was the syndication manager of the video website My Damn Channel, obtained Schmidt's permission to reuse the footage, appending it to the end of a blooper video to "play" that person offstage after the mistake or gaffe in a similar manner as getting the hook in the days of vaudeville. The appending of Schmidt's video to other blooper and other viral videos became popular, with such videos usually accompanied with the title Play Him Off, Keyboard Cat or a variant. "Keyboard Cat" was ranked No. 2 on Current TV's list of 50 Greatest Viral Videos. In 2009, Schmidt became owner of Bento, another cat that resembled Fatso, and which he used to create new Keyboard Cat videos, until Bento's death in March 2018. The owner, Charlie Schmidt, has made certain remarks that he may adopt or get a “Keyboard Cat 3.0”

Meaning (Philosophy of Language)
In the philosophy of language, meaning "is a relationship between two sorts of things: signs and the kinds of things they intend, express, or signify". The types of meanings vary according to the types of the thing that is being represented. Namely: There are the things in the world, which might have meaning; There are things in the world that are also signs of other things in the world, and so, are always meaningful (i.e., natural signs of the physical world and ideas within the mind); There are things that are always necessarily meaningful, such as words, and other nonverbal symbols. The major contemporary positions of meaning come under the following partial definitions of meaning: Psychological theories, involving notions of thought, intention, or understanding; Logical theories, involving notions such as intension, cognitive content, or sense, along with extension, reference, or denotation; Message, content, information, or communication; Truth conditions; Usage, and the instructions for usage; and Measurement, computation, or operation.

Scarr-Rowe Effect
In behavioral genetics, the Scarr-Rowe effect, also known as the Scarr-Rowe hypothesis, refers to the proposed moderating effect of low socioeconomic status on the heritability of children's IQ. According to this hypothesis, lower socioeconomic status and greater exposure to social disadvantage during childhood leads to a decrease in the heritability of IQ, as compared to children raised in more advantaged environments. It is considered an example of gene–environment interaction. This hypothesized effect was first proposed by Sandra Scarr, who found support for it in a 1971 study of twins in Philadelphia, and these results were replicated by David C. Rowe in 1999. A 2015 meta-analysis found the effect was predominant in the United States while less evident in societies with robust child welfare systems.
