Abstract The problem of ballast water has been present in the world for the last hundred years, but it has grown and become more complex with the increasing intensity of overseas traffic. Introduction of various species from different parts of the world threatens flora and fauna, especially regarding small and closed seas, such as the Adriatic Sea. New species cause an interruption of the existing food chain which keeps the natural balance and purity of the sea. Many domicile organisms in the sea have been disappearing due to changes in environmental conditions, which significantly impairs the sea-water quality. This paper deals with different possible ways of sea and port protection from ballast water, starting with administrative measures, up to proposals of technologies by which those waters could be treated. The problem of ballast water is of particular concern in the Montenegrin part of the Adriatic Sea, and the protection proposal is given.

Looss created the genus Philophthalmus in 1899 for flukes infesting the eyes of birds. Twelve species of trematodes have been recorded from the eyes of avian hosts in different parts of the world, but hitherto none has been described from India. The following account deals with the description of two new species of Philophthalmus which were recovered from birds of prey in Hyderabad.

Special Mention

A large number of nanoplankton species originally found in the sea around Britain have now been collected from other northern temperate waters (see Leadbeater, 1972 c; Manton & Leadbeater, 1974). It was, therefore, of considerable interest to collect nano-plankton from warmer waters such as those of the Adriatic and Mediterranean. The larger plankton of both the Adriatic and Mediterranean has been the subject of investigation by a succession of scientists from many countries (for references see Tregouboff, 1952). Whilst many workers acknowledged the importance of the smaller plankton from these areas (e.g. Bernard, 1958; Lalami-Taleb, 1971) only a few have attempted to study and identify species belonging to this group. In this respect the meticulous work of Lohmann (1902a, 1911) and Schiller (19136, 19256) requires special mention. Lohmann (1902a), working on the phytoplankton from the coast of Sicily, first used the technique of pumping sea water through filter paper and in this way he was able to collect and identify many minute species for which he later suggested the name ‘ Nannoplankton’ (Lohmann, 1911). On a later excursion to the Atlantic Ocean, Lohmann (1911) found the gentle centrifugation of sea-water samples was a more satisfactory and less destructive way of concentrating small cells. Schiller's most important contribution concerns a phytoplankton study carried out as part of an international hydrobiological survey of the Adriatic Sea during the years 1911–14. Schiller's findings confirmed many of Lohmann's previous observations and added a further range of new species including many green flagellates (Schiller, 1913 6, 1925b).

It would be interesting and profitable to look back to see how closely the applications of science to the sea had followed its developments and technical achievements ashore. In contrast to the wealth of literature on the classical geography of the oceans and the achievements of the early voyagers there is no balanced account of the scientific investigation. Such an account would include the work of men like Boyle, who, in his observations and experiments about the saltness of the sea (1672), gave the first satisfactory explanation of this phenomenon, and showed th at it would be necessary to make a great number of observations in different climates and different parts of the world to determine the degrees of saltness with any certainty. He arranged for travellers to collect samples for him. Lavoisier (1772) and Bergman (1777) analysed samples of sea water and named the principal dissolved salts. In 1812, Alexander Marcet, a London physician, made the remarkable discovery that although the total amount of salt varied from place to place according to the balance of evaporation and precipitation, the principal constituents were always present in the same proportions. Although this was almost a premonition based on the analysis of not more than fourteen samples from different parts of the Atlantic Ocean, it has stood the test of time.

The idea of ecotourism is being promoted and supported, by growing numbers of people and groups in different parts of the world, as a major means of dealing with the damaging effects of tourism. Yet the meaning of the term varies among different people, projects, and places. Evidence from national parks, where this type of tourism has been promoted for many years, shows that such tourism can cause substantial long-term cumulative changes in environment. Concepts such as ecotourism, green tourism, and sustainable tourism development, are general in their nature and have to be described, planned, and assessed, in detail on the ground in terms of the socioeconomic and environmental conditions applying in different places. In this respect, careful planning and management procedures are needed not only for ecotourism but indeed for all forms of tourism.

Abstract Increasing water consumption is a problem faced by the world; one of its solutions is reusing water. Reuse is about changing processes that result in polluted water byproducts so that the resulting water is usable again. Our major problem is to reuse unusable or polluted water. We are not treating the water, but we are changing processes to make water byproducts usable again in the same process or even a different process. Our solution is to reuse ballast water in transporting oil. Oil ships are heading from one country to another, and they are loaded with oil. These ships return to be loaded with ballast water instead of oil to prevent the risk of overturning this ship. In other words, the ballast water is used to make the ship stable which is the purpose of the ballast water to return to their original countries in peace. Our goal is to purify this ballast water mixed with oil residues by relying on the density difference. The first step is to place a source of solid air in the tanks to provide some bubbles inside the tank. Secondly, put some of the iron peels inside the tanks to stick these peels with the bubbles, then by a magnetic field attracts the pollutant bubbles attached to the iron scales, and the ballast water remains in the tank to be used again. Before writing a test plan, we demonstrated two design requirements. The first one is ballast water quality which has two parts the turbidity and oil, grease, and all extractable matter by chloroform in the water, while the second design requirement is the environmental impact. By making a test, the results were astounding because it achieved the design requirements that we put into making this project applicable for reusing this polluted water after purifying it.

In March 2020, the World Health Organization (WHO) declared that the COVID-19 outbreak can be characterized as a pandemic. Human-to-human transmission of the SARS-CoV-2 virus may initially be blamed as the first cause of spread, but can an infection be contracted by ingestion of contaminated food or touching contaminated food surfaces? Recently cold-chain food contamination has been indicated as a possible source of many human cases in China. However, the risk of a food-related COVID-19 infection is still debated since the virus may reach people through a fresh product or packaging, which have been touched/sneezed on by infected people. This review summarizes the most recent evidence on the zoonotic origin of the pandemic, reports the main results regarding the transmission of SARS-CoV-2 through food or a food chain, as well as the persistence of the virus at different environmental conditions and surfaces. Emphasis is also posed on how to manage the risk of food-related COVID-19 spread and potential approaches that can reduce the risk of SARS-CoV-2 contamination.

ABSTRACT A reference standard is widely sought for use in the quantitative bioassay of pituitary gonadotrophin recovered from urine. The biologic similarity of pooled urinary extracts obtained from large numbers of subjects, utilizing groups of different age and sex, preparing and assaying the materials by varying techniques in different parts of the world, has lead to a general acceptance of such preparations as international gonadotrophin reference standards. In the present study, however, the extract of pooled urine from a small number of young women is shown to produce a significantly different bioassay response from that of the reference materials. Gonadotrophins of individual subjects likewise varied from the multiple subject standards in many instances. The cause of these differences is thought to be due to the modifying influence of non-hormonal substances extracted from urine with the gonadotrophin and not necessarily to variations in the gonadotrophins themselves. Such modifying factors might have similar effects in a comparative assay of pooled extracts contributed by many subjects, but produce significant variations when material from individual subjects is compared. It is concluded that the expression of potency of a gonadotrophic extract in terms of pooled reference material to which it is not essentially similar may diminish rather than enhance the validity of the assay.

This book charts the transformation of one of the world's great religions during an age marked by world wars, genocide, nationalism, decolonization, and powerful ideological currents, many of them hostile to Christianity. The book traces how Christianity evolved from a religion defined by the culture and politics of Europe to the expanding polycentric and multicultural faith it is today—one whose growing popular support is strongest in sub-Saharan Africa, Latin America, China, and other parts of Asia. The book sheds critical light on themes of central importance for understanding the global contours of modern Christianity, illustrating each one with contrasting case studies, usually taken from different parts of the world. Unlike other books on world Christianity, this one is not a regional survey or chronological narrative, nor does it focus on theology or ecclesiastical institutions. The book provides a history of Christianity as a popular faith experienced and lived by its adherents, telling a compelling and multifaceted story of Christendom's fortunes in Europe, North America, and across the rest of the globe. It demonstrates how Christianity has had less to fear from the onslaughts of secularism than from the readiness of Christians themselves to accommodate their faith to ideologies that privilege racial identity or radical individualism.
