The increase in the number and tonnage of modern vessels, the large differences in their handling qualities, the dimensions of straits and ports, and consequently navigation difficulties encountered in poor visibility, have led the authorities involved to set up control centres responsible for the functions of traffic regulation and aids to navigation. Several systems ensuring these functions have been set up over the last few years or are currently under way. Using modern technology these systems meet a wide range of operational requirements and are characterized by extensive modularity, allowing system implementation in successive stages.

This paper by the Harbour Master of Marseilles and his adviser on radio aids describes the system of traffic surveillance developed by the Port of Marseilles. The paper was originally presented at the Fourth International Symposium on Vessel Traffic Services held in Bremen from 28 to 30 April 1981.The creation of an Integrated Traffic Regulation Centre (ITRC) was the solution chosen by the Port of Marseilles Authority to deal with the numerous traffic problems that had arisen in recent years in the Gulf of Fos due to the extremely rapid growth of the maritime traffic, especially oil tankers, converging on the Gulf which now totals over 80 million tonnes per year and the general tendency towards the construction and operation of very large ships, conspicuous in the development of oil tankers but now to a lesser extent in other categories of ship also.

Captain Dickens, an Elder Brother of Trinity House, here describes the history and function of the lighthouse authorities in catering for the needs of shipping around our coasts, and discusses the wide range of navigational aids now in use. The paper was presented at an Ordinary Meeting of the Institute held in London on 18 November 1970 with the President, Rear Admiral G. S. Ritchie, C.B., D.S.C., in the chair.One of the first lights to be set up to aid mariners was the Pharos erected at the entrance to the port of Alexandria in 270 B.C. and said to have been visible at sea for 40 miles. With the development of maritime traffic, more and more lights have been established so that shipping can proceed in comparative safety around the various seaboards of the world. In the United Kingdom the early lights and beacons were either privately owned, attached to various monasteries or managed by the Trinity Houses, which were corporations of seafaring men.

It is argued that there is great commercial value in transferring as much of vehicle-handling qualities assessment as possible from the prototype testing domain to the predictive engineering domain. Man—machine system thinking is necessary to provide a firm basis for progress. Also, the newer opportunities in vehicle chassis engineering to introduce information enhancement and control intervention systems pose human factors problems. It is possible for such systems to do more harm than good. Some descriptions of conventional mixtures of prediction and testing are given and the driving activity is analysed. A conceptual framework involving the specification of vehicle characteristics, which contribute to the subjective judgements made by drivers, is set up. Examples in the categories are explained. The major chassis enhancement systems in production or in late development and their contributions in the various categories are discussed. Quality judgements are shown to be made by a very complex process, containing conflict and requiring very wide-ranging test conditions for the full picture to be revealed. It is considered that a conceptual classification, such as that put forward, is necessary to allow the design of research programmes which will yield fundamental, generic and practically useful results.

Historically, those societies that have the longest tradition in multicultural policies are settler societies. The question of how to deal with temporary migrants has only recently aroused their interest. In Europe, temporary migration programmes have a much longer history. In the period after WWII, a wide range of legal frameworks were set up to import temporary workers, who came to be known as guest workers. In the end, many of these ‘guests’ settled in Europe permanently. Their presence lay at the basis of European multicultural policies. However, when these policies were drafted, the former mobility of guest workers had been forgotten. This chapter will focus on this mobility of initially temporary workers, comparing the period of economic growth 1945-1974 with the years after the 1974 economic crisis. Further, it will look at the kind of policies that were developed towards guest workers in the era before multiculturalism. This way, it shows how their consideration as temporary residents had far-reaching consequences for the immigrants, their descendants and the receiving societies involved. The chapter will finish by suggesting a number of lessons from the past. If the mobility-gap between guest workers and present-day migrants is not as big as generally assumed, then the consequences of previous neglect should serve as a warning for future policy making.

Pittenweem Priory began life as the caput manor of a daughter-house established on May Island by Cluniac monks from Reading (c. 1140). After its sale to St Andrews (c. 1280), the priory transferred ashore. While retaining its traditional name, the ‘Priory of May (alias Pittenweem)’ was subsumed within the Augustinian priory of St Andrews. Its prior was elected from among the canons of the new mother house, but it was many decades before a resident community of canons was set up in Pittenweem. The traditional view, based principally on the ‘non-conventual’ status of the priory reiterated in fifteenth-century documents, is that there was ‘no resident community’ before the priorship of Andrew Forman (1495–1515). Archaeological evidence in Pittenweem, however, indicates that James Kennedy had embarked on significant development of the priory fifty years earlier. This suggests that, when the term ‘non-conventual’ is used in documents emanating from Kennedy's successors (Graham and Scheves), we should interpret it more as an assertion of superiority and control than as a description of realities in the priory.

Knowledge presented by Oral History (OH) is unique in that it shares the tacit perspective, thoughts, opinions and understanding of the interviewee in its primary form. While teachers, lecturers and other education specialists have at their disposal a wide range of primary, secondary and tertiary sources upon which to relate and share or impart knowledge, OH presents a rich source of information that can improve the learning and knowledge impartation experience. The uniqueness of OH is presented in the following advantages of its use: it allows one to learn about the perspectives of individuals who might not otherwise appear in the historical record; it allows one to compensate for the digital age; one can learn different kinds of information; it provides historical actors with an opportunity to tell their own stories in their own words; and it offers a rich opportunity for human interaction. This article discusses the placement of oral history in the classroom set-up by investigating its use as a source of learning material presented by the National Archives of Zimbabwe to students in the Department of Records and Archives Management at the National University of Science and Technology (NUST). Interviews and a group discussion were used to gather data from an archivist at the National Archives of Zimbabwe, lecturers and students in the Department of Records and Archives Management at NUST, respectively. These groups were approached on the usability, uniqueness and other characteristics that support this type of knowledge about OH in a tertiary learning experience. The findings indicate several qualities that reflect the richness of OH as a teaching source material in a classroom set-up. It further points to weak areas that may be addressed where the source is considered a viable strategy for knowledge sharing and learning. The researchers present a possible model that can be used to champion the use of this rich knowledge source in classroom education at this university and in similar set-ups.

Today, more than forty countries of the world are engaged in the development of military-purpose robots. A number of unique mobile robots with a wide range of capabilities are already being used by combat and intelligence units of the Armed forces of the developed world countries to conduct battlefield intelligence and support tactical groups. At present, the issue of using the latest information technology in the field of military robotics is thoroughly investigated, and the creation of highly effective information management systems in the land-mobile robotic complexes has acquired a new phase associated with the use of distributed information and sensory systems and consists in the transition from application of separate sensors and devices to the construction of modular information subsystems, which provide the availability of various data sources and complex methods of information processing. The purpose of the article is to investigate the ways to increase the autonomy of the land-mobile robotic complexes using in a non-deterministic conditions of modern combat. Relevance of researches is connected with the necessity of creation of highly effective information and control systems in the perspective robotic means for the needs of Land Forces of Ukraine. The development of the Armed Forces of Ukraine management system based on the criteria adopted by the EU and NATO member states is one of the main directions of increasing the effectiveness of the use of forces (forces), which involves achieving the principles and standards necessary for Ukraine to become a member of the EU and NATO. The inherent features of achieving these criteria will be the transition to a reduction of tasks of the combined-arms units and the large-scale use of high-precision weapons and land remote-controlled robotic devices. According to the views of the leading specialists in the field of robotics, the automation of information subsystems and components of the land-mobile robotic complexes can increase safety, reliability, error-tolerance and the effectiveness of the use of robotic means by standardizing the necessary actions with minimal human intervention, that is, a significant increase in the autonomy of the land-mobile robotic complexes for the needs of Land Forces of Ukraine.

Endocrine disrupting compounds can affect the hormone system in organisms. A wide range of endocrine disrupters were found in sewage and effluents of municipal wastewater treatment plants. Toxicological evaluations indicate that conventional wastewater treatment plants are not able to remove these substances sufficiently before disposing effluent into the environment. Membrane technology, which is proving to be an effective barrier to these substances, is the subject of this research. Nanofiltration provides high quality permeates in water and wastewater treatment. Eleven different nanofiltration membranes were tested in the laboratory set-up. The observed retention for nonylphenol (NP) and bisphenol A (BPA) ranged between 70% and 100%. The contact angle is an indicator for the hydrophobicity of a membrane, whose influence on the permeability and retention of NP was evident. The retention of BPA was found to be inversely proportional to the membrane permeability.

This study was conducted with the aim of evaluating the role of information and information resources in the awareness, control, and prevention of COVID-19. This study was a descriptive-analytical survey in which 450 participants were selected for the study. The data collection instrument was a researcher-made questionnaire. Descriptive and inferential statistics were used to analyze the data through SPSS. The findings show that a wide range of mass media has become well known as information resources for COVID-19. Other findings indicate a significant statistical difference in the rate of using information resources during COVID-19 based on age and gender; however, this difference is not significant regarding the reliability of information resources with regard to age and gender. Health information has an undisputable role in the prevention and control of pandemic diseases such as COVID-19. Providing accurate, reliable, and evidence-based information in a timely manner for the use of resources and information channels related to COVID-19 can be a fast and low-cost strategic approach in confronting this disease.
