Purpose. To analyze the significance of V. Ogorodnikov’s 1929 article on finds from Olsky (Zaviyalova) Island in the historiography of archaeological research in northeastern Russia. Results. An analysis of his published materials, in the context of the history of archaeological research in Northeast Asia in the 18th – first quarter of the 20th century shows that this was, in fact, the first professional publication on archaeological research in this part of northeast Asia. Until that time, sporadic publications about random finds and their fragmentary descriptions did not give a holistic picture of human existence in these territories. It was also the first Russian archaeological publication post-revolution on the antiquities of the north of the Far East. However, Ogorodnikov’s article, from the day of its publication, was forgotten, and in all further archaeological research, both in Northeast Asia as a whole, and on Zaviyalova Island and in Taui Bay in particular, was not mentioned and was not analyzed by the archaeologists who conducted research there, although the conclusions made by him were confirmed by further work. This, apparently, was due to the fact that although he was a well-known Siberian historian and the first Dean of the Department of History of Irkutsk University, Ogorodnikov was unjustly repressed for political reasons in 1933 and died in 1938 in a Gulag camp. Despite the fact that he was politically rehabilitated in 1957, his name has not yet returned to the historiography of archeology of Northeast Asia. This publication aims to fill this gap. The Neolithic age of the archaeological materials declared and published by Ogorodnikov, previously unforeseen and not justified by anyone for Northeast Asia, was fully confirmed by further research. Conclusion. The publication by Ogorodnikov in 1929 featuring results of the first excavations in Taui Bay on Olsky (Zaviyalova) Island is a significant milestone in archaeological research in the North-East of Russia.

Aim: Characteristics of enterovirus infection morbidity and study of peculiarities of enterovirus circulation on some territories of Russia in 2017. Materials and methods: We investigated more than 5000 samples from the patients with enterovirus infection. The isolation and identification of enteroviruses were conducted by virological method and by partial sequencing of the genome region VP1. Phylogenic trees were constructed according to the method of Bayesian Monte Carlo Markov Chain. Results: Epidemic process and clinical picture of enterovirus infection were not the same on different territories. Peculiarities of the circulation of different types of enteroviruses on the territories were also different. In Saratov region 65% of cases were represented by enterovirus meningitis. In Murmansk region and in the Komi Republic enterovirus infection with exanthema prevailed, 95% and 60% correspondingly. In Saratov region enterovirus ECHO18 was the etiological agent of enterovirus meningitis. In Murmansk region and in the Komi Republic the cases were connected mainly with Coxsackieviruses A6. The strains of enterovirus ECHO18 were distributed to three clusters. The strains which provoked enterovirus meningitis in Saratov region belonged to cluster 3, they were formed separately from other strains of this enterovirus type and differed from the stains of ECHO18 which circulated in the North-West of Russia. The strains of Coxsackieviruses A6 identified in the North-West of Russia belonged to three sub-genotypes 5, 6, 8 of pandemic genotype of CoxsackievirusesA6. The majority of the strains belonged to sub-genotypes 6 and 8 which in 2017 dominated in the structure of Coxsackieviruses A6 in the North-West of Russia and in Russia. Conclusion: Epidemic peaks of enterovirus infection represented by different clinical forms of the disease were provoked by different types of enteroviruses. Enterovirus ECHO18 was the etiological agent of enterovirus meningitis. The main etiological factors of enterovirus infection with exanthema were Coxsackieviruses A6 of different sub-genotypes.

The territory of Ukraine is located between the areas of two subspecies of Moustached Warbler Acrocephalus melanopogon (Temminck, 1823) - A. m. melanopogon (Temminck, 1823) and A. m. albiventris (Kazakov, 1974). In the North-West Black Sea region, the nesting of the nominative subspecies has been proven, while the second one nests in the East Azov Sea region. By 2016, neither in the North Azov Sea region, nor in the South-East of Ukraine, this species was not observed. However, there are certain meetings of solitary birds in the adjacent regions during migrations on the Eastern Syvash on 21.10.2006 and westwards of the Don mouth on the Mius River bank on 05.09.2011. It was photographed for the first time on 24.04.2016 on the Shaitanka River near the Novodonetske village Velykonovosilkivskyi district of Donetsk region. Its nesting is reliably proven on 30.04.2020 on the Mokri Yaly River of the same region. On this river, there are plant communities with different proportions of common reed (Phragmites australis) and narrowleaf cattali (Typha angustifolia) grow in some places around open areas of the water area. It's on such sections of the river the Moustached Warbler males were observed. On a 600 m long section of the river, 3-4 males were observed. 2 males were caught, which were assigned to the subspecies of A. m. albiventris by color and measurements. On 19.05.2020 there were 5 eggs in one of the found nests. Egg sizes, mm: 18.0x13.0; 18.0x12.9; 16.9x12.9; 17.6x12.9; 17.9x12.9. The nest was located at a height of 250 mm above the water. Nest measurements, mm: D=85; d=50; H=53; h=43. It is suggested that in the South-East of Ukraine, birds appeared on nesting grounds due to the increase in the range of the subspecies in the north-west direction over the last 20 years due to climate warming. It is quite likely to find new localities of the Moustached Warblers on small rivers, large ponds or reservoirs in the southern part of Donetsk, eastern part of Zaporizhzhia or south – eastern part of Dnipropetrovsk regions.

Freshwater snails are known to serve as first intermediate hosts for various parasitic diseases such as schistosomosis, amphistomosis and fasciolosis. Two freshwater snail species, Lymnaea natalensis, Krauss 1848 and Bulinus tropicus, Krauss 1848 were sampled from five localities in Gauteng and one locality in the North West Province from 2007 to 2010. These snails were collected in order to study their cercarial sheddings. They were found to be infected with three different types of strigea cercariae, of which the morphology was studied using standard light and scanning electron microscopy techniques.

Of all the states in ancient Greece, Attica seems to have had the most interesting and complete system of land defences. A chain of important fortresses, of most of which there are still considerable remains, follows the line of the Kithairon–Parnes range: Eleutherai, Oinoe, Panakton, Phyle, Dekeleia, Aphidna and Rhamnous. It may appear at first that this series of strongholds was designed expressly to mark off Athenian territory, but whilst incidentally and in large measure they served this end, in origin they were intended rather to defend the various roads from Attica into Boeotia. A fresh examination of these forts and their relation to the Attic frontier may be of some service and interest.The natural boundary of Attica on the N.W. is the mountain ridge which begins on the Halkyonian sea-coast behind Aigosthena and continues almost due eastward to the Straits of Euboea, reaching the sea at Cape Kalamos. It is not surprising, therefore, to learn that the early tradition made the Megarid and Attica into a single kingdom. Plato, describing an idealised primitive Attica, gives as the boundaries the Isthmus and the heights of Kithairon and Parnes extending down to the sea, with Oropos on the right and the Asopos on the left.


On the evening of the 9th of July, 1792, between seven and eight o'clock, at Alverstoke, near Gosport, on the sea coast of Hampshire, there came up, in the south-east, a cloud with a thunder-shower; while the sun shone bright, low in the hori­zon to the north-west. In this shower two primary rainbows appeared, AB and AC, (Tab. I.) not concentric, but touching each other at A, in the south part of the horizon; with a secondary bow to each, DE and DF (the last very faint, but discernible), which touched likewise, at D. Both the primary were very vivid for a considerable time, and at different times nearly equally so; but the bow AB was most permanent, was a larger segment of a circle, and at last, after the other had vanished, became almost a semicircle; the sun being near setting. It was a perfect calm, and the sea was as smooth as glass.

Abstract Firths are geomoiphological and hydrological sites typical for flat, neutral coast of no tidal sea basins. There in the greatest extend is preserved the geological column of the correlative Pleistocene- Holocene sediments. They make possible to reveal the Quaternary evolution of the contact zone „land-sea“. Firths are one of the most reliable indicators for the Quaternary Earth crust movements. Along the Black Sea coast most widely are developed the firths in the north - west and the west periphery, where they form a classic firth type coast. This report examines the results of complex studies of Batova river firth, located (developed) on the North Bulgarian Black Sea coast.

The Ordnance Survey of Great Britain is now in its 167th year. Founded in 1791, it has provided a map coverage of this country which is unexcelled in its completeness and in the range of its scales. All the most important towns are now being mapped on a 1/1250 (50-in,) scale in a new survey, over 60 per cent of which have now been completed. Only a few mountainous and uninhabited regions are excluded from the 1/2500 (25-in.) scale which otherwise covers the whole country. Consequential from this scale is a further series of maps at scales of 1/10,560 (6-in.), 1/25,000 (2½-in.), 1/63,360 (1-in.), 1/126,720 (½-in.), and 1/253,440(¼-in.). Except for the north-west of Scotland the 1/25/000 (2½-in.) scale map covers the whole of the country, but the 1/126,720 (½-in.) scale has only recently been started and will take some years to complete.An unusual feature of the whole of these map series when compared with other national surveys is the attention it pays to the mapping of antiquities. This is not confined to the delineation of those ancient features which have size and bulk which make it impossible to omit them from any map. A big range of antiquities is shown. The current list shows 107 different types ranging in date from the earliest times down to the 18th century. Some, like burial mounds, are small; others, like major hill-forts or Roman town sites, cover many acres, while others of linear type like Hadrian’s Wall or Offa’s Dyke approach or exceed 100 miles in length. Apart from this kind of antiquity which can still be recognized on the ground, there are many places indicated where important finds of portable objects have been made, and the sites of battles and other historic events are shown.

Most of the exposures of Cretaceous Limestone in Jamaica were faithfully indicated on the Geological Survey map of Sawkins and Brown in 1865. They are limited in extent and occur at certain places among the complex of the older or Blue Mountain series of rocks that project from beneath the covering of White Limestone that covers the greater part of the Island. Contrary to one's common experience in many European countries the Cretaceous beds in Jamaica do not approach the sea coast in any part except near Port Antonio on the north-east coast, where the Trappean shales reach the sea; near St. Ann's Bay, about the centre; and at Green Island, on the north-west coast, where the Barrettia Limestone occurs within 2 miles of the sea. Elsewhere the sea coast is occupied by the White Limestone or beds that overlie it, with the exception of stretches along the north coast around Lucea Harbour and between Port Maria and Annotta Bay, occupied by the Carbonaceous Shales of Lower Eocene age.
