This book examines the various patterns of nominal and pronominal address used in Jamaica and Trinidad, the two most populous islands of the English-speaking Caribbean. Given that the Anglo-Caribbean ...context has so far been largely neglected in address research, this study aims to provide an in-depth analysis of the linguistic means Jamaicans and Trinidadians have at their disposal and make use of to address each other. A particular focus will be on variation in the speakers' address behaviour with regard to their sex, age, social class, ethnicity, and regional background. The study draws both on data from a self-compiled corpus of postcolonial Jamaican and Trinidadian literary works, and on questionnaire and interview data collected during fieldwork. This book contributes to the ever-growing body of research in the field of nominal and pronominal address, and will be relevant to researchers interested in the fields of sociolinguistics, pragmatics, and World Englishes.

can be a pathogen and causes development of peptic ulcer disease in a ...certain state of the macroorganism. It is well established that
infection is the main cause of chronic gastritis and peptic ulcer disease (PUD). Decontamination of the gastric mucosa with various antibiotics leads to
elimination and longer remission in this disease. However, the reasons for repeated detection of
in recurrent PUD after its successful eradication remain unclear. The reason for the redetection of
in recurrent PUD can be either reinfection or ineffective anti-Helicobacter therapy. The administration of antibacterial drugs can lead not only to the emergence of resistant strains of microorganisms, but also contribute to the conversion of
into the resting (dormant) state. The dormant forms of
have been shown to play a potential role in the development of relapses of PUD. The paper discusses morphological
forms, such as S-shaped, C-shaped, U-shaped, and coccoid ones. The authors proposes the classification of
according to its morphological forms and viability.

Recently, we have shown in dogs that the gastric residence time of expandable fibrous dosage forms can be prolonged by coating the fibers with a semi-permeable, strengthening coating. ...In this work on pigs, the effect of the volume fraction of the coating, φc, on the expansion, mechanical strength, and gastric residence time is investigated. Three methacrylic acid-ethyl acrylate-coated fibrous dosage forms with φc = 0.025, 0.041, and 0.068 were prepared and tested. Upon administering to a pig, the dosage forms expanded to a normalized radial expansion of 0.5–0.6 in 5, 8, and 10 h, respectively. The expanded dosage forms resided in the stomach and fragmented after 11, 25, and 31 h. The fragments then passed into the intestines and dissolved in 2–3 h. Models suggest that upon contact with gastric fluid, a hydrostatic pressure develops in the fibers due to the inward diffusion of water. The hydrostatic pressure in turn induces a tensile stress in the coating and the dosage form expands. The tensile stress and the expansion rate are inversely proportional to φc. The expanded dosage form eventually fractures due to the loads applied by the contracting stomach walls. The post-expansion mechanical strength and the time to fracture increase steeply with φc. The models predict the experimental results reasonably well. Thus, by increasing φc, dosage form fracture is delayed and the gastric residence time prolonged.
Quaternions are a number system that has become increasingly useful for representing the rotations of objects in three-dimensional space and has important applications in theoretical and applied ...mathematics, physics, computer science, and engineering. This is the first book to provide a systematic, accessible, and self-contained exposition of quaternion linear algebra. It features previously unpublished research results with complete proofs and many open problems at various levels, as well as more than 200 exercises to facilitate use by students and instructors. Applications presented in the book include numerical ranges, invariant semidefinite subspaces, differential equations with symmetries, and matrix equations.
Designed for researchers and students across a variety of disciplines, the book can be read by anyone with a background in linear algebra, rudimentary complex analysis, and some multivariable calculus. Instructors will find it useful as a complementary text for undergraduate linear algebra courses or as a basis for a graduate course in linear algebra. The open problems can serve as research projects for undergraduates, topics for graduate students, or problems to be tackled by professional research mathematicians. The book is also an invaluable reference tool for researchers in fields where techniques based on quaternion analysis are used.
Let f∈Sk(Γ0(N)) be a normalized Hecke eigenforms of integral weight k and level N≥1. In the article, we establish the asymptotics of power moment associated to the sequences {λf⊗f⊗f(Q(x̲))}Q∈SD,x̲∈Z2 ...and {λf⊗sym2f(Q(x̲))}Q∈SD,x̲∈Z2 where SD denotes the set of inequivalent primitive integral positive-definite binary quadratic forms (reduced forms) of fixed discriminant D<0. As a consequence, we prove results concerning the behaviour of sign changes associated to these sequences.
Many ambitious and experimental game forms don't fit into the digital download or retail distribution channels that support so-called “traditional” video games. Instead, these games are supported by ...a new global movement in video game curation. This special edition of the Video Game Art Reader features an international collaboration of video game professionals working together to create a resource for game exhibition organization, design, and curation. Professionals, artists, and others who organize and curate video game exhibitions and events act within a rhizomatic network of methods, missions, and goals. They establish organizations like galleries, collectives, and non-profits. Methods of sharing video games as critical cultural phenomena continue to evolve and expand. Conceived during the first meeting of GAIA (Game Arts International Assembly), the Game Art Curators Kit documents and shares the collective experience of an international network of video game curators and organizers. Sharing practical tips on everything from accessibility to preservation, the book also serves as a guide to support a new global movement in video game curation.
