Engineers and artists have teamed to create combinations of fire and water that have dazzled people at tourist attractions, festivals, and the Olympic Games. At the University of the Pacific in Stockton, California, mechanical engineering professor Ed Pejack and student Eric Eubanks designed a small-scale fountain for educational and demonstration purposes, adapting parts used in irrigation and a camping fuel can. Alan Robinson and Mark Fuller invented a fountain that illuminates water jets with colored flames. Kiki Pettit, a computer programmer, has designed, built, and installed water fountains that incorporate liquid fuel to produce floating flames that flow with water. The water in the Olympic cauldron serves functional and esthetic purposes. The water film flowing down the glass creates random wave patterns that ripple the image of the fire inside. A computer system controls the water flow rate based on temperature of the return water.

Grundtvig and Golden Age CopenhagenBy Flemming Lundgreen-NielsenThe article has originally been given as a public lecture at the University of Copenhagen during the Golden Days in Copenhagen festival in September 1994. By way of introduction the question is posed to which extent Grundtvig belongs to the Golden Age period in Danish cultural and artistic life. Though he lived in the capital for 65 years, he never orientated himself towards the places that interested most other educated Copenhageners. The University rejected his applications for a professorate, and he in return vehemently attacked the dead learning of the institution. He hardly ever went to the Cathedral or other of the city churches, since he was at odds with most of the clergy. The art of acting he considered to be organized hypocrisy and accordingly avoided the Royal Theatre. He had good relations to the Kings (and Queens!), but did not involve himself in the affairs of the Royal Court. Unlike most contemporary writers and artists, he never took the Grand Tour of the Continent, in fact apart from four journeys to England (1829-31 and 1843) and one to Norway (1851), he stayed at home in his study, travelling in time through his comprehensive readings rather than in actual space. As he grew older, he got quite popular among his younger followers and ended up becoming one of the tourist attractions of the city, as witnessed 1872 by the young English poet Edmund Gosse briefly before Grundtvig’s demise.Grundtvig cared little for the kind of elite culture that dominated Copenhagen for most of his life. Though singing of national ballads was inaugurated during his 1838 lectures and since then has been a part of Danish tradition for public meetings, he had no ear for music at all and never communicated with the fine composers who set music to his texts. Sculpture and painting he rejected as base materialistic arts, only acknowledging the Danish sculptor of European fame, Bertel Thorvaldsen, because of his unassuming and genial personality, not on account of his reliefs and statues. Even his fellow poets he in general criticized harshly, excepting a few works by B.S. Ingemann. On the whole he did not think that, the first third of the 19th century constituted any Golden Age: it was a period filled with drowsiness and shallow entertainment, devoid of anything but sensualistic or even materialistic pleasures.Inspired by writers from Classical Greece and Rome, older humanists such as professor K.L. Rahbek nourished a hopeless longing for a lost Golden Age. Modem romanticists, however, such as the philosopher Henrich Steffens, the poet Adam Oehlenschl.ger and the above mentioned Thorvaldsen strove to regain or recreate a true Golden Age in the near future. Spurred on by Norse mythology as well as by his Christian belief, Grundtvig from around 1824 increasingly came to share this attitude. He distinguished between Guld-Alder (Golden Age) as a thing of the past, and Gylden-Aar (literally: Golden Year) as a state of earthly and heavenly happiness soon to be achieved or even existing in the present moment-the word refers to the Biblical Year of Jubilee as rendered in a medieval Danish translation of the Old Testament. Unfortunately no all-encompassing examination of Grundtvig’s use of these terms has been executed, but from his secular poetry a series of instances are given in the following, starting with a somewhat overlooked poem called »Gylden-Aaret« from January 1834, celebrating three moments in the life of King Frederik VI: his recovery from a serious illness in Schleswig and his triumphant return to Copenhagen in August 1833, hisbirthday in January 1834 and his 50 years’ jubilee as a ruler in the following April. The modem Gylden-Aar is defined as happiness for all of the people through enlightenment about life, procured by the king and all the fine poets surrounding him. Thus Grundtvig gives a unique priority to the art of poetry. No matter what occurred to Denmark in the rest of Grundtvig’s life-time, he managed to interpret the events as pains of child-birth heralding the approaching Gylden-Aar rather than as death throes. Instead of confining himself to the refined small-scale topics of most contemporary poets, he time and again energetically prophecied about the expected Gylden-Aar as a solid historical fact. In a period where elitist art according to the doctrines of romantic poetics was literally idolized, he maintained that the highest form of art consists in organizing society and the lives of common people so that all innate talents and latent possibilities are being developed in the due course of time. He believes this to be happening under the benevolent reign of the present Danish kings, among others things because the Danes have been reared to pay attention to each other and are generally uninterested in pursuing power and glory, honour and greatness. Grundtvig deduces this attitude partly from the role played by the peasants in the formation of the modem Danish national character, partly from the influence of the exeptionally loving, loveable and lovely Danish womanhood. Even the geographical position of Copenhagen between the Sound (the scene of the heroic battle against Lord Nelson in 1801) and the impressive beeches of Charlottenlund Forest (a beautiful and peaceful idyll of nature) becomes symbolic of Denmark’s state of mind, demonstrating a harmony between nature and history, reality and dream, simplicity and majesty, people and royalty. Though Grundtvig remained much of an outsider in Golden Age Copenhagen, his interest in the common citizen, in family and home and everyday life, relates him to the then current concept of ’cozy’ (hyggelig) Biedermeier art after all. Because of his view of universal history, he was able to give depth and significance even to the smallest and most trivial elements in his environment. Grundtvig simply could not help converting the exclusive Golden Age of the poets and artists into a fruitful Gylden-Aar for the whole nation.

Each of the 65 inhabited islands of Vanuatu hosts its own unique linguistic environment in which varying degrees of multilingualism are found. This paper defines various types of small-scale multilingual settings in Vanuatu and explores what sociohistorical factors have led to them. This paper is based on first-hand observations and primary data collected by the authors in four locations in the Pacific Island nation of Vanuatu since 2016: two neighboring villages of Emae Island (Makatu and Tongamea), North Malekula, and on Maewo Island. The assessments of multilingualism in these examples from Vanuatu were qualitative, based on observations of sociolinguistic practices in each of these areas, as well as data from language history and language use surveys carried out in each place. Through defining and comparing the types of multilingualism present in the four case studies, we identify patterns in the social and historical processes that lead to various kinds of multilingualism: (a) interaction of linguistic and sociocultural identities and (b) mobility of both individuals and entire speech communities. The examples described in this paper are used to highlight the diversity of multilingualism found in Vanuatu and to explore how their differing linguistic environments and histories have contributed to their varying degrees of multilingualism. This paper makes an original contribution to knowledge about the small-scale multilingual situations in Vanuatu, offering descriptions of previously undocumented and endangered multilingual environments. Through an examination of the sociocultural motivations for multilingualism, alongside historical migrations of speaker groups and marked sociolinguistic identities, this paper contributes to research on why and how small-scale multilingualism can develop. Furthermore, this paper provides the foundation for future, more rigorous investigations into the small-scale multilingual situations of this highly understudied region.

This paper presents small-scale low-speed maneuvering tests with an oceanographic research vessel and the comparison with mathematical model using the real time maneuvering simulator developed by the University of São Paulo (USP). The tests are intended to verify the behavior of the vessel and the mathematical model under transient and low speed tests. The small-scale tests were conducted in deep and shallow waters, with a depth-draft ratio equal to 1.28, in order to verify the simulator ability to represent the vessel maneuverability on both depth conditions. The hydrodynamic coefficients used in the simulator model were obtained by CFD calculations and wind tunnel model tests carried out for this vessel. Standard turning circle and accelerating turn maneuvers were used to compare the experimental and numerical results. A fair agreement was achieved for shallow and deep water. Some differences were observed mainly in the initial phase of the accelerating turn test.

Many parts of the western US is rural in nature and consequently do not have electrical distribution lines in many parts of farms and ranches. Distribution line extension costs can run from $15,000 to $25,000 per mile, thereby making availability of electricity to small water pumping projects economically unattractive. Solar photo-voltaic (PV) powered water pumping is more cost effective in these small scale applications. Many western states including Wyoming are passing through fifth year of drought with the consequent shortages of water for many applications. Wyoming State Climatologist is predicting a possible 5–10 years of drought. Drought impacts the surface water right away, while it takes much longer to impact the underground aquifers. To mitigate the effect on the livestock and wildlife, Wyoming Governor Dave Freudenthal initiated a solar water pumping initiative in cooperation with the University of Wyoming, County Conservation Districts, Rural Electric Cooperatives, and ranching organizations. Solar water pumping has several advantages over traditional systems; for example, diesel or propane engines require not only expensive fuels, they also create noise and air pollution in many remote pristine areas. Solar systems are environment friendly, low maintenance and have no fuel cost. In this paper the design, installation and performance monitoring of the solar system for small scale remote water pumping will be presented.

Small-scale fisheries provide food security, livelihoods and income to millions of people but their management still presents a challenge to managers and other stakeholders due to problems in gathering suitable information and its incorporation in fisheries policy. Fishers are a key source of knowledge for assessment of both extractive capacity and value in small-scale fisheries, in addition to providing a broad array of cultural knowledge. The increasing recognition of the value of incorporating traditional fishing knowledge in freshwater, riverine, lacustrine and coastal and marine fisheries management is now evident in international conventions and published literature. The purpose of these guidelines is to make it easier for users to recognise and include fishers’ knowledge as an important data stream in resource management. The report includes details on the breadth of knowledge that can be gathered, how it can be gathered, and how this information can be applied to support sustainable fisheries policy and broader applications in society. With case studies from Africa, Asia, the Caribbean, Central and South America, and the Pacific.

Due to the undesirable effects of the gap between citizens to access and use information and communication technologies (ICT), most researchers have been paying much attention to the threat of a digital divide. Unfortunately an amazingly large number of people do not have the abilities to use the ICTs in a proper way and, therefore, cannot draw advantages from its usage. As a result, digital divide is commonly regarded as a potential barrier for participation in the information society. This study measure the digital divide in Saudi Arabia by analyzing the results of a small-scale study conducted at the University KAU, regarding students’ and university members’ perceptions toward the usage of ICT. This analysis measure the digital divide concerning some factors like gender, educational level using a questionnaire. The analysis shows that KAU has no digital divide. Key words: digital divide, information and communications technology, ICT, diffusion of technology, second order effects.

A number of years ago I began to form and arrange in the Anatomical Museum of the University of Edinburgh a collection of the hair of the head to illustrate the varieties in colour and character which exist in the Races of Men. In a classification of the races based on the colour and characters of the hair, anthropologists have usually adopted the suggestion made by Bory de St Vincent, and have divided them into two groups: Leiotrichi, with straight, smooth hair; and Ulotrichi, with woolly or frizzly hair. Each of these again is capable of subdivision.In this memoir I intend especially to examine the Ulotrichi, which comprise two well-marked subdivisions. In one the hair is very short, and is arranged in small spiral tufts, the individual hairs in which are twisted on each other, a mat-like arrangement of compact spiral locks closely set together being the result. In the other the hair is moderately long, the locks are slender, curled or spirally twisted in a part of their length and terminate at the free end in a frizzly bush-like arrangement. Ulotrichous hair is found in various African races, in the aborigines of Tasmania, New Guinea, the Melanesian Islands in the Pacific, in the Negritos of the Malay Peninsula and of some of the islands of the Asiatic Archipelago. The Leiotrichi are Australians, Polynesians, Mongols, Malays, Indians, Arabs, Esquimaux and Europeans.
