Carbonate and clastic sediments of Jurassic and Cretaceous age are exposed along the fault-scarp of Djebel Nefusa in north-western Libya. Previous geological investigations have been mainly restricted to the eastern sector of the scarp. Recent studies by the authors in the western sector of Djebel Nefusa and on equivalent sediments in southern Tunisia have allowed the first regional interpretation of these rocks.The area studied lies geographically and geologically at the edge of the Saharan Platform, a large cratonic block, composed of rocks of Precambrian-Palaeozoic age. To the north and east lies a downfaulted sedimentary basin (Gabes-Sabratha Basin) containing a large thickness of Mesozoic sediments. The location of the sections measured along Djebel Nefusa are depicted in Fig.1.The stratigraphic nomenclature of the rock succession of Djebel Nefusa was first established in the east and continued laterally towards the west by later workers. Difficulties in the application of this nomenclature are presented by the recognition of facies changes previously overlooked by earlier investigators. However, as a framework for understanding these changes and the sedimentary processes which caused them, the stratigraphy erected by Magnier (1963) is adopted.

AbstractNorth Brae is the first gas condensate field in the UK to be produced by gas recycling. The field lies at the western margin of the South Viking Graben in UK Block 16/7a. Estimated recoverable reserves are 178 MMBBL of condensate and 798 BCF of dry gas. First hydrocarbon production was in April 1988 from the Brae 'B' platform.The reservoir is composed of coarse clastic sediments of the Upper Jurassic Brae Formation which were deposited by debris flows and turbidity currents in a submarine fan setting adjacent to an active fault scarp. The Brae Formation now abuts impermeable Devonian rocks of the Fladen Ground Spur to the west. The reservoir is capped by the Kimmeridge Clay Formation, which also provided the source of the hydrocarbons.

The population of Red Deer (Cervus elaphus L., 1758) in Tulcea county (Romania) The presence of the Red Deer in the North-western parts of Tulcea County is an example of the natural expansion of a species spreading area. In North Dobrogea, this mammal first occurred only forty years ago. The first specimens were spotted on Cocoşul Hill (on the territory of Niculiţel area) in 1970. Peak numbers (68 individuals) were registered in the spring of 1987. The deer population (67 specimens in 2007) of this county extended along 10 km from West to East and 20 km from North to South over a total of 23,000 ha (55% of which was forest land) in the East of the Măcin Mountains and in the West of the Niculiţel Plateau.

Abstract This paper deals with the topic of conservative West-Russianist ideology and propaganda during World War I. The author analyzes the most prominent newspaper of the movement at the time – Severo-Zapadnaia Zhizn (The North-Western Life). The discourse of the newspaper is analyzed from the perspective of Belarusian nation-building, as well as from the perspective of Russian nationalism in the borderlands. The author explores the ways in which the creators of the periodical tried to use the rise of the Russian patriotic feelings to their advantage. Appealing to the heightened sense of national solidarity which took over parts of Russian society, the periodical tried to attack, delegitimize and discredit its ideological and political opponents. Besides the obvious external enemy – Germans, Severo-Zapadnaia Zhizn condemned socialists, pacifists, Jews, borderland Poles, Belarusian and Ukrainian national activists, Russian progressives and others, accusing them of disloyalty, lack of patriotism and sometimes even treason. Using nationalist loyalist rhetoric, the West-Russianist newspaper urged the imperial government to act more decisively in its campaign to end ‘alien domination’ in Russian Empire, and specifically to create conditions for domination of ‘native Russian element’ – meaning Belarusian peasantry, in the Belarusian provinces of the empire.

Scharffenbergbotnen is a 3 × 6 km large basin of interior ice drainage on the north-western side of Heimefrontfjella in Dronning Maud Land, Antarctica. The elevation at the bottom of the depression is 1142 m a.s.l., while bedrock immediately to the south-east of this point rises to more than 2750 m. Ice enters the basin mainly from a low ice divide (1250 m a.s.l.) in the west but also through a 400 m high icefall in the east. Two separate blue-ice areas constitute approximately half the surface of the basin, while the other half is snow-covered. As part of SWEDARP (Swedish Antarctic Research Programme) 1988 a research project to study the origin and mass balance of this basin has been initiated. A net of 28 stakes has been established for studies of ablation and ice movement (Fig. 1). The ice thickness was measured by radio-echo sounding (Fig. 2) and particular care was devoted to get the correct ice depths at the entrance to the basin. The ice thickness along a central section of the basin varied from 1000 m in the west to 400 m at the bottom of the depression. In order to explain the ablation two automatic weather stations (Aanderaa 2700) were operated during the field season (mid-January to mid-February 1988). One was placed in the bottom of the depression, the other 13 km to the west in an area where a small net accumulation took place during the field season. The latter station should record “normal” weather. Sensors registering wind speed, wind gust, wind direction, incoming solar radiation, air temperature and relative humidity were installed at both weather stations, while reflected solar radiation, net radiation and air pressure were measured only at Scharffenbergbotnen. All sensors except the air pressure sensor were placed 270 cm above the ground, and all were read every 10 minutes. Ablation measurements were carried out between 16 January and 18 February on 24 of the stakes. 12 of these stakes were standing in snow. All but one recorded ablation and, as no signs of melting could be seen, all ablation must be due to evaporation and perhaps for the snowy areas some wind erosion. The average ablation rate for the whole field season was 0.7 mm w.eq. per day with a standard deviation of 0.3. Stakes in blue ice showed slightly higher values than those in snow. For January, when air temperatures always were above −10°C, the average ablation rate was 1.2 mm w.eq. per day. A regional difference in ablation rate across the depression was also measurable. Maximum ablation took place immediately below the arête forming the north-eastern boundary of the basin and diminished towards south-west. Below the arête the ablation rate was above 1 mm w.eq. per day for the whole field season and more than 2 mm w.eq. per day during January. A comparison of weather data between the two stations showed the following main differences. In the depression the temperature showed no daily variation and relative humidity varied between 40 and 60%. The weather at the other station was characterised by colder nights and weaker winds as well as by a relative humidity between 60 and 80%. The reason for the regional variation in ablation can be explained by almost constant easterly winds during January and the drop in altitude (between 300 and 500 m) along the north-western arête. On 11 February 1988 the weather station at Scharffenbergbotnen was converted into a system for satellite (Argos) transmission of weather data to Europe. The transmission seems to have been successful but the data are not yet processed. At present (January 1989) one of us is remeasuring the stakes (ablation and ice movement) during SWEDARP 1989. Preliminary results sent by radio point towards a yearly net ablation rate of 120 mm w.eq. for the blue-ice area in the bottom of the depression. 25% of the ablation took place during the field season 1988, but 75% has evaporated between 18 February 1988 and mid-January 1989. Probably most of the evaporation took place during December 1988 and January 1989, which means a very high daily evaporation rate (2.5 mm w.eq. per day).

The 1968 excavations were a continuation of the investigations that have been in progress at Knowth since 1962. In brief, this work is establishing that there is a cemetery of Passage Graves at Knowth. This consists of the large tumulus (Site I) with a number of smaller tombs in its immediate vicinity. This group is situated on a low hill that on the west overlooks the River Boyne at a point a couple of miles downstream from Slane where the river takes a sharp turn to the left [I]. MAIN MOUND At Knowth a tract of land that is close to a halfmile in length and one fifth of a mile in greatest width (c. 800 m. x 340 m.) is above the 200-ft. contour (60 m.) but even the highest part of this is only slightly over the 200-ft. mark. The large mound is situated towards the north-western extremity of this ridge and the smaller tombs are

Harappa is a village, having a station on the North-Western Railway, in the Montgomery District, Panjāb: it is situated in lat. 30° 38′, long. 72° 52′, on the south bank of the Ravi, some fifteen miles towards the west-by-south from Montgomery. The place is now of no importance: but extensive ruins and mounds, one of which rises to the height of sixty feet, indicate that the case was otherwise in ancient times; and it has yielded thousands of coins of the “Indo-Scythians” and their successors. Amongst other objects of interest from this place, there are the three seals, full-size facsimiles of which are given in the accompanying Plate. The original seals are now in the British Museum, in the Department of British and Mediæval Antiquities in charge of Mr. Read. In all three cases, the substance of these seals seems to be a claystone, hardened by heat or some other means. In the originals, the devices and characters are sunk: the illustrations represent impressions from the originals, with the devices and characters reversed, as compared with the way in which they lie in the originals, and standing out in relief. The animal on A has been held to be a bull, but not an Indian bull, because it has no hump: another opinion, however, is that it may be a male deer of some kind. The animal on C has a tail of such a nature as to suggest that this creature cannot be a deer. On A the hind legs were not fully formed; and it is possible that a similar tail has been omitted there.

During the excavations at Mycenae in 1953, a Protogeometric cist burial was discovered in the House of Shields, sunk into the floor of its west room. This burial, numbered Tomb PG 601, was published, with other burials, in BSA XLIX 258 ff. In the summer of 1954 Professor Wace uncovered three further burials in the House of Shields. These, at his most kind invitation, I publish here.General situation (Fig. 1). Whereas tomb PG 601 was found at the southern end of the west room of the House of Shields, these three, here numbered 602, 603, and 604, appeared in the north-western corner of this same room. Only a few feet separate the one from the others, as will be clear from the plan, and 602 and 603 seem to have been placed under the shelter of the west wall. The area had been to a certain extent disturbed, but whether there may have been further burials between 601 and this group of three I cannot tell. None was found in the excavation.

The paper is devoted to belt buckles of the early Sarmatian period of the Turgay steppes. Turgay deflection is a vast territory located in the north-western part of Kazakhstan. In the north, Turgay deflection turns into the west Siberian lowland, and in the south it turns into the Turan lowland. In the west, the bend touches the Trans-Ural plateau, while in the east - the Kazakh hills. Three buckles originating from burial № 5A of mound 1 of the Karatomar burial ground and mound 1 of the Kenysh 3 mound group are analyzed. The paper deals with the cultural and chronological position of Turgay belt buckles in the context of the distribution of such products of the belt headset on the territory of Eurasia. The problem of the origin and chronology of these items is also touched upon. Buckles similar to the Karatomar one have so far been found only on the territory from Central Asia and Kazakhstan to the Lower Volga region. Kenysh buckle finds an analogy from the Volga-Don interfluves to the north of China. In General, types of buckles, similar to Turgay, existed in the II-I centuries BC. The studied buckles should be considered in the context of the general fashion for wearing a belt headset made of metal, bone and stone, associated with the military activity of the Huns.
