Early Stage Design

Even though in 1987 there were only a dozen SWATH (smali-waterplane-area twin-hull) craft and ships afloat around the world, word of their markedly superior seakeeping performance is spreading rapidly. The number of SWATH vessels is likely to double within five years. As in many other areas of technology, the United States and Japan are the acknowledged leaders in the development and practical application of the SWATH concept. This paper reviews the characteristics of existing SWATH craft and ships from the standpoint of the stated seakeeping objective. Hull form differences between four SWATH craft and ships, including the Navy's SSP Kairnalino, are analyzed and interpreted. Important considerations for the early-stage design of a SWATH ship are discussed. Differences in the range of feasible hull form geometries for coastal areas and unrestricted ocean operations, and for low-speed versus moderately high-speed applications, are pointed out.

The article presents the experience of developing an elective course program for future foreign language teachers studying at Tyumen State University. The content of the course is based on the principles of communication and variability and is focused on the development of the communicative, psychological, pedagogical and technological competencies of the future teacher. The creation by the teacher of favorable pedagogical conditions for a positive cultural identification of the student’s personality allows the child to become aware of the multicultural space of the world. The professional portfolio of a novice teacher includes techniques, methods and technologies that can be used for further pedagogical modeling.

Mysidacea are common sublittoral crustaceans that inhabit all coasts in the world. In this study, the population characteristics and the reproductive biology of Metamysidopsis neritica Bond-Buckup & Tavares, 1992 were studied in the surf zone of a south Brazilian beach (Atami). Mysids were sampled at monthly intervals from August, 1999 to July, 2000 (total of 29,490 individuals). Individuals were classified into six population categories. The highest abundance occurred in May (8,665) and August (6,415), and lowest in September (336) and December (368). Three main generations were identified, namely the summer, fall and winter generations. The winter generation was the longest (four to five months). The fall generation lasted four months, and the summer one extended from three to four months. Ovigerous females occurred throughout the year, with a greater proportion in July. The number of eggs or larvae varied from one to 16. Weak associations were found between female length and egg number, egg volume, and the number of larvae with and without eyes. Egg volume increased during the coldest season, whereas the smallest values were recorded during summer. These results suggest a possible direct relationship between egg volume and generation longevity.

The recent emergence of the SARS-CoV-2 in China has raised the spectre of a novel, potentially catastrophic pandemic in both scientific and lay communities throughout the world. In this particular context, people have been accused of being excessively pessimistic regarding the future consequences of this emerging health threat. However, consistent with previous research in social psychology, a large survey conducted in Europe in the early stage of the COVID-19 epidemic shows that the majority of respondents was actually overly optimistic about the risk of infection.

Clonal Population Structure

ABSTRACT Cryptococcus gattii has recently emerged as a pathogen of humans and animals in the temperate climate of Vancouver Island, British Columbia (B.C.). The majority (∼95%) of the isolates from the island belong to the VGII molecular type, and the remainder belong to the VGI molecular type. The goals of this study were to compare patterns of molecular variation among C. gattii isolates from B.C. with those from different areas of the world and to investigate the population structure using a comparative gene genealogy approach. Our results indicate that the C. gattii population in B.C. comprises at least two divergent lineages, corresponding to previously identified VGI and VGII molecular types. The genealogical analysis of strains suggested a predominantly clonal population structure among B.C. isolates, while there was evidence for sexual recombination between different molecular types on a global scale. We found no geographic pattern of strain relationships, and nucleotide sequence comparisons revealed that genotypes among isolates from B.C. were also present among isolates from other areas of the world, indicating extensive strain dispersal. The nucleotide sequence diversity among isolates from B.C. was similar to that among isolates from other areas of the world.

Looking at the historical flow of Islamic development in Indonesia as such, the author took an analysis that the future prospects of Islam in Indonesia have a great opportunity to continue to develop, be it in the fields of politics, economics, education, social, and culture. This can be seen from the history of Islam in Indonesia that continues to develop until now, this is the early stage of the emergence of awareness of the Indonesian nation of the importance of planting religious values in Indonesian society so that the Indonesian nation can meet the future not only with science and technology but also in the balance by IMTAQ.  The era of globalization in the 21st century that has begun at this time, Islam in Indonesia has apparently exerted a huge influence on the advancement of Islam in the world. Although the existence of Islam today is really faced with a fairly severe challenge that requires the involvement of various parties concerned. With regard to this, strategic efforts need to be made, among others: by providing knowledge, skills, and piety in all fields (religious, political, economic, social, cultural, educational) so as to give birth to creative, innovative, independent and productive people considering the world to come is a competitive world. Keywords: Islam, The Future, Indonesia

The Mind

City marketing tries to position cities in the mind of the public, although the process of creating and communicating city brands is still at an early stage of its development. One of the main tools for the communication of these brands is now the World Wide Web. This chapter describes the results of two combined studies (qualitative and quantitative) that analyzes a sample of official city Web sites. The results show that official Web sites of cities give much attention to ease of navigation, but interactivity is much less implemented, especially between users. Furthermore, some lack of attention to the communication aspects of city brands can also be found. Finally, the chapter submits a number of improvement proposals.
