With little else than the trouble of surveying one of the finest of Edinburgh landscapes, the tourist beginning work amongst the débris just to the south of where Samson's ribs overhang the road, and continuing on the road along Salisbury Crags to Holyrood Palace, will meet with a continuous display of the relations specially of zeolitic minerals, and their containing rocks. If he care to pursue the literature of the subject, Daubrée's investigations on the genesis of zeolites, as well as Allport's, Bonney's, and Geikie's petrological researches into the microscopy of the rocks in question, will suggest oven more lengthened studies.

The ruins at Yanıkhan form the remains of a Late Roman village in the interior of Rough Cilicia some 8 kilometres inland from the village of Limonlu on the road to Canbazlı (see Fig. 1). The site has not been frequently visited by scholars, and the first certain reference to its existence was made by the late Professor Michael Gough after his visit on 2 September 1959. Yanıkhan is now occupied only by the Yürüks who for years have wintered on the southern slopes of Sandal Dağ. The ancient settlement at Yanıkhan consisted of a village covering several acres. The remains are still extensive, and some, especially the North Basilica, are very well preserved, but there has been considerable disturbance in recent years as stone and rubble have been removed in order to create small arable clearings. The visible remains include many domestic buildings constructed both from polygonal masonry without mortar and from mortar and rubble with coursed smallstone facing. There are several underground cisterns and a range of olive presses. The countryside around the settlement has been terraced for agricultural purposes in antiquity, and is, like the settlement itself, densely covered with scrub oak and wild olive trees. The most impressive remains are those of the two basilical churches which are of little artistic pretension, but considerable architectural interest. The inscription which forms the substance of this article was found on the lintel block of the main west entrance of the South Basilica.

I derive the materials of the present paper from some memoranda which I find amongst my archaeological notes and which relate to certain explorations to which I was not a party, made so long ago as 1887. I have thought that the particulars then obtained may be deemed sufficiently interesting to deserve a record in the history of Trojan archaeological discovery.The subject is one of the four small tumuli dotted about and near the hill of Balli-Dagh, the crest of which according to the now exploded theory of Le Chevalier (1785) was supposed to represent the Pergamos of Troy. In a memoir contributed to the Journal of the Archaeological Institute of 1864, I proved that the site in question was no other than that of the ancient city of Gergis. In the same paper I gave an account of the results of the excavation of one of the group of three tumuli on Balli-Dagh, the so-named Tomb of Priam. The other two, namely Le Chevalier's Tomb of Hector, and an unnamed hillock, were excavated respectively by Sir John Lubbock (about 1878) and Dr. Schliemann (1882) without result. The present relates to the fourth mound on the road between the villages of Bournarbashi and Arablar (as shown in the published maps), which goes by the name of Choban Tepeh (Shepherd's hillock) and the Tomb of Paris, according to Rancklin (1799).

The development of operating speed models has been the subject of numerous research studies in the past. Most of them present models that aim to predict free-flow speed in conjunction with the road geometry at the curved road sections considering various geometric parameters e.g., radius, length, preceding tangent, deflection angle. The developed models seldomly take into account the operating speed profiles of motorcycle riders and hence no significant efforts have been put so far to associate the geometric characteristics of a road segment with the speed behavior of motorcycle riders. The dominance of 4-wheel vehicles on the road network led the researchers to focus explicitly on the development of speed prediction models for passenger cars, vans, pickups, and trucks. However, although the motorcycle fleet represents only a small proportion of the total traffic volume motorcycle riders are over-represented in traffic accidents especially those that occur on horizontal curves. Since operating speed has been thoroughly documented as the most significant precipitating factor of vehicular accidents, the study of motorcycle rider's speed behavior approaching horizontal curves is of paramount importance. The subject of the present paper is the development of speed prediction models for motorcycle riders traveling on two-lane rural roads. The model was the result of the execution of field measurements under naturalistic conditions with the use of an instrumented motorcycle conducted by experienced motorcycle riders under different lighting conditions. The implemented methodology to determine the most efficient model evaluates a series of road geometry parameters through a comprehensive literature review excluding those with an insignificant impact to the magnitude of the operating speeds in order to establish simple and handy models.

The costs of construction and the future maintenance of expressways and motorways have a significant impact on the choice of technologies for their construction. The subject of the article is the analysis of the costs of construction and maintenance of rigid (concrete) and flexible (asphalt mixtures) pavements in Poland. The construction technologies and maintenance scenarios in service were analysed for selected pavement constructions of rigid and flexible motorways and expressways. The costs of construction and maintenance of these pavements in national conditions were determined. The fourth quarter of 2015 was adopted as the initial price level. On the basis of the analysis of the costs of construction and maintenance of the analysed structures, the advantage of rigid constructions made of cement concrete was demonstrated, especially in the aspect of the surface maintenance. The cost assessment was carried out for 30 years of exploitation. The concrete pavements on the road network in Poland have been used for over 20 years. They are present both on low-class roads and on the highest-class roads, i.e. motorways and expressways.

Few would argue that the democratisation of South Africa is one of the most fascinating examples of constitutional engineering during the latter half of the 20th century. This article recounts the negotiating process leading up to the adoption of the Constitution of 1996, and highlights the main features of the Constitution. The features discussed are majority government, the principle of constitutional supremacy, the content and application of the Bill of Rights – with some emphasis on its impact so far on social change –, the role of the independent judiciary, the principle of co-operative government which governs the relationship between the three spheres of government, and the ways in which the diversity prevalent in the South African society has been accommodated. Some comments are also made on the necessity for the creation of a human rights culture to support the new Constitution. The article concludes with the remark that, although serious obstacles remain, a solid start has been made on the road to a constitutional democracy with justice for all.

This chapter describes the growing demonstrations during the 1960s, as the sit-in movement spreads to Texas. Elder activists join the young in expressing their demands. In less than three years after the first sit-ins, the revived African American civil rights movements would succeed in desegregating public accommodations in urban areas throughout Texas and the South, counting a major coup on the road to their larger goals of equal treatment, improved economic opportunities, and real political power.

Aristodemus, a Phigalian by birth, was tyrant of Megalopolis for around fifteen years in the first half of the third century b.c., possibly from the time of the Chremonidean War (267–262) until around 251, when he was murdered by two Megalopolitan exiled citizens, Megalophanes and Ecdelus, pupils of the Academic Arcesilaus. While giving an account of his violent death, Pausanias, none the less, draws a very positive portrait of him, also mentioning the nickname ‘the Good’ which he probably read on Aristodemus' grave. Pausanias also reports the foundation of two temples by the tyrant, both dedicated to Artemis. At 8.35.5 he locates one of the two temples at thirteen stades from Megalopolis on the road to Methydrion, so to the north. There, he says, is a place named Scias, where there are ruins of a sanctuary of Artemis Sciaditis. At 8.32.4, Pausanias briefly refers to the temple of Artemis Agrotera at Megalopolis. He says only that the sanctuary was on a hill in the south-east district of the polis, and adds that it was dedicated as an ἀνάθημα by the tyrant as well.

The paper opens by describing the background of automobile rig testing, with the word “rig” defined as “a contrivance or makeshift with the means at one's disposal”. A range of equipment is desirable so that rigs can, after use on one particular test, be reassembled to form some other device, after the fashion of a constructional toy. It is made clear that no indoor test can replace the testing of vehicles on the road, or tractors on the farm, but useful and quickly obtained results can be acquired with certain problems. Such work can be useful supplementary aid to a development programme. As the essence of the subject is variety and speed, it is felt necessary to give several illustrations to emphasize the simplicity and ingenuity required in rig construction and design. The use of photographs in lieu of engineering drawings as an aid to later reconstruction is mentioned. Test rigs illustrated include those for fatigue failure in suspension, frame, body, and transmission; impact failures; body and chassis weaving; tractor and car transmissions; valve port flow; roller bearing wear; and vehicle air resistance measurements. Sufficient technical data are given to show the scope and results of the tests.

The article discusses the experience of organizing and implementing labor initiatives of the personnel of the West Siberian Railway in the first half of the 1980s, aimed at solving problems associated with increasing the freight turnover of railway transport in the eleventh five-year East and today. In improving labor productivity, saving fuel, electricity and efficient use of rolling stock, one of the important points was the Moscow initiative, supported on the road, to drive heavy and long trains, which made it possible to significantly increase throughput without increasing the number of trains. The search for the optimal option in terms of the carrying capacity and the number of wagons in the train has become the subject of hard work by the staff of the West Siberian Railway.
