Tonsillolith
Tonsilloliths, also known as tonsil stones, are soft aggregates of bacterial and cellular debris that form in the tonsillar crypts, the crevices of the tonsils. While they occur most commonly in the palatine tonsils, they may also occur in the lingual tonsils. Tonsil stones are common. Tonsilloliths have been recorded weighing from 0.3 g to 42 g. Protruding tonsilloliths may feel like foreign objects lodged in the tonsil crypt. They may be a nuisance and difficult to remove, but are usually not harmful. They are one of the causes of bad breath and always give off a putrid smell.

Grandiosity
In the field of psychology, the term grandiosity refers to an unrealistic sense of superiority, characterized by a sustained view of one's self as better than others, which is expressed by disdainfully criticising them, overinflating one's own capability and belittling them as inferior; and refers to a sense of personal uniqueness, the belief that few other people have anything in common with oneself, and that one can only be understood by a few, very special people. The personality trait of grandiosity is principally associated with narcissistic personality disorder (NPD), but also is a feature in the occurrence and expression of antisocial personality disorder, and the manic and hypomanic episodes of bipolar disorder.

Computer Designed Architecture and Architects
The designs generated by computer algorithms are becoming such a serious part of designers’ work that some are beginning to question whether they are more the work of computers than humans. There are also increasing suggestions that software development will eventually lead to a situation where humans in the profession will become redundant. This review article aims to present the currently used, implemented, and planned computer technologies employed in the design and consider how they affect and will affect the work of architects in the future.

The Mysteries of the White Truffle: Its Biology, Ecology and Cultivation
Tuber magnatum Picco is the most expensive of the truffles and a great deal of research has been carried out in an attempt to solve the mysteries of its ecology and biology. However, considerable work remains to be done particularly on those secrets of its life cycle that remain a mystery. It is known that T. magnatum is heterothallic, but it has yet to be determined how fertilization occurs between the two strains of different mating types. It is also known that the white truffle is an ectomycorrhizal fungus, and its mycorrhizas can be produced in greenhouses, but then they seem to disappear in the field. The role of other soil microorganisms, fungi and bacteria, on its soil mycelial development and fructification is intriguing but is far from being completely understood. All these uncertainties have made the cultivation of T. magnatum extremely difficult and only recently have we had the scientific proofs that it is possible. Even so, many questions remain unanswered and the management practices of T. magnatum plantations are still to be better defined to also enable the taming of this truffle.

Interplay between Polyphenols and Lysyl Oxidase Enzymes
Collagen, the most abundant structural protein found in mammals, plays a vital role as a constituent of the extracellular matrix (ECM) that surrounds cells. Collagen fibrils are strengthened through the formation of covalent cross-links, which involve complex enzymatic and non-enzymatic reactions. Lysyl oxidase (LOX) is responsible for catalyzing the oxidative deamination of lysine and hydroxylysine residues, resulting in the production of aldehydes, allysine and hydroxyallysine. These intermediates undergo spontaneous condensation reactions, leading to the formation of immature cross-links, which are the initial step in the development of mature covalent cross-links. Additionally, non-enzymatic glycation contributes to the formation of abnormal cross-linking in collagen fibrils. During glycation, specific lysine and arginine residues in collagen are modified by reducing sugars, leading to the creation of Advanced Glycation End-products (AGEs). These AGEs have been associated with changes in the mechanical properties of collagen fibers.

Plug-in Electric Vehicles in Japan
The fleet of light-duty plug-in electric vehicles in Japan totaled about 303,000 highway legal plug-in electric vehicles in circulation at the end of 2019, consisting of 152,320 all-electric passenger cars, 141,680 plug-in hybrids, and 8,720 light-commercial vehicles. The rate of growth of the Japanese plug-in segment slowed from 2013, with annual sales falling behind Europe, the U.S. and China since then. The segment market share fell from 0.68% in 2014 to 0.59% in 2016. Then the market share increased to 1.2% in 2017, and fell to 1.1% in 2018, and to 0.9% in 2019. Norway surpassed Japan as the country with the third largest plug-in car stock in use in 2019. The decline in plug-in car sales reflects the Japanese government and the major domestic carmakers decision to adopt and promote hydrogen fuel cell vehicles instead of plug-in electric vehicles, although the first commercially produced hydrogen fuel cell automobiles began in 2015. (As of April 2018), the Nissan Leaf all-electric car ranked as the all-time top selling plug-in electric vehicle in the country, with over 100,000 units sold since December 2010. Ranking second is the Mitsubishi Outlander P-HEV with 34,830 units delivered through August 2016, followed by the Toyota Prius PHV with 22,100 units sold through April 2016. (As of December 2012), Japan was the country with the highest ratio of quick charging points to electric vehicles (EVSE/EV), with a ratio of 0.030 (As of December 2012). The country's charging infrastructure included 1,381 public quick-charge stations and around 300 non-domestic slow charger points. The Japanese government has set up a target to deploy 2 million slow chargers and 5,000 fast charging points by 2020.

Evolution of Domestic Goats
Goat evolution is the process by which domestic goats came to exist through evolution by natural selection. Wild goats — medium-sized mammals which are found in noticeably harsh environments, particularly forests and mountains, in the Middle East and Central Asia — were one of the first species domesticated by modern humans, with the date of domestication generally considered to be 8,000 BCE. Goats are part of the family Bovidae, a broad and populous group which includes a variety of ruminants such as bison, cows and sheep. Bovids all share many traits, such as hooves and a herbivorous diet and all males, along with many females, have horns. Bovids began to diverge from deer and giraffids during the early Miocene epoch. The subfamily Caprinae, which includes goats, ibex and sheep, are considered to have diverged from the rest of Bovidae as early as the late Miocene, with the group reaching its greatest diversity in the ice ages. The tribe Caprini would subsequently develop from Caprids who arrived in the mountainous areas of Eurasia and split into goats and sheep in response to a further geographic separation. The ancestors of sheep remained in the foothills and the ancestors of goats went to higher altitudes. This divergence resulted in the adaption of the ancestors of goats to a mountainous environment, producing many of the traits considered peculiar to the species. During the ice ages a genus called Capri evolved which would then diverge into the modern goat species, along with several species of ibex. It is commonly held that the earliest domestication was of the bezoar ibex in the Zagros Mountains. These earliest domesticated goats were used to produce meat and milk for Neolithic farmers, along with providing many of the materials required to built residences and tools. Following the domestication of goats over 300 breeds have been established for a variety of purposes, including for the maximation of milk production and for meat. Domestication and the selective breeding which resulted had a significant effect on the direction of goat evolution, with goats developing behaviour which is considered to have been influenced by consistent proximity to humans. Selective breeding also significantly increased the physical diversity of modern goats, producing characteristics not seen in wild goats.

Per- and Polyfluoroalkyl Substances (PFASs) Destruction Technologies
Per- and polyfluoroalkyl substances (PFASs) are a family of highly toxic emerging contaminants that have caught the attention of both the public and private sectors due to their adverse health impacts on society. The widely adopted separation technologies can remove PFASs from being in contact with humans; however, they remain in the environment and continue to pose health risks. On the other hand, the destructive technologies can effectively destroy PFAS compounds and fully address society’s urgent need to remediate this harmful family of chemical compounds.

Transducer Technologies for Biosensors and Their Wearable Applications
Biosensors refer to the collaboration of receptors that recognize target analytes and transducers that translate this recognition into a detectable signal. Biological molecules such as enzymes, nucleic acids, antibodies, or their synthetic analogues can serve as bio-receptors to bind the analyte of interest. To form a biosensor device that detects or measures the biological events or changes, the targeted matching of the bio-receptor and the analyte should be evaluated quantitatively, making the transducers indispensable components of a biosensor. Availability of various bio-receptors, transducers, and possible combinations of both components constitute various ways to classify biosensors. Compared to conventional sensors based on rigid semiconductors, metals, and ceramics, elastomers are advantageous since they exhibit the highest level of strain behavior for wearable applications.

Diagnosis of Plant Virus Diseases
Among the plant pathogens, viruses (and viroids), which are transmitted by a living organism called a vector, are the major infectious agents that cause plant disease. Once a plant virus infects a susceptible host, it can spread to another plant by means of vector-mediated transmission (horizontally) or from parents to offspring (vertically). Since accurate diagnosis methods are of pivotal importance for viral diseases control, the current and emerging technologies for the detection of these plant pathogens are described.
