This study focused on the geochemical and sedimentological characterization of recent sediments from two marine sites (S1 and E1) located in the North Adriatic Sea, between the Po River prodelta and the Rimini coast. Major and trace metal concentrations reflect the drainage area of the Po River and its tributaries, considered one of the most polluted areas in Europe. Sediment geochemistry of the two investigated sites denote distinct catchment areas. High values of Cr, Ni, Pb and Zn detected in sediments collected in the Po River prodelta (S1 site) suggest the Po River supply, while lower levels of these elements characterize sediments collected in front of the Rimini coast (E1 site), an indication of Northern Apennines provenance. Historical trends of Pb and Zn reconstructed from the sedimentary record around the E1 site document several changes that can be correlated with the industrialization subsequent to World War II, the implementation of the environmental policy in 1976 and the effects of the Comacchio dumping at the end of 1980. At the S1 site, the down core distributions of trace elements indicate a reduction of contaminants due to the introduction of the Italian Law 319/76 and the implementation of anti-pollution policies on automotive Pb (unleaded fuels) in the second half of the 1980s.

In this study, petrological, structural, geochemical, and geochronological analyses of the Statherian alkali feldspar granite and porphyritic alkali feldspar granite in the southwestern part of the Korean Peninsula were conducted to examine petrogenesis of the granitoids and their tectonic setting. Zircon U-Pb dating revealed that the two granites formed around 1.71 Ga and 1.70–1.68 Ga, respectively. The results of the geochemical analyses showed that both of the granites have a high content of K2O, Nb, Ta, and Y, as well as high FeOt/MgO and Ga/Al ratios. Both granites have alkali-calcic characteristics with a ferroan composition, indicating an A-type affinity. Zircon Lu-Hf isotopic compositions yielded negative εHf(t) values (−3.5 to −10.6), indicating a derivation from ancient crustal materials. Both granite types underwent ductile deformation and exhibited a dextral sense of shear with a minor extension component. Based on field relationships and zircon U-Pb dating, it was considered that the deformation event postdated the emplacement of the alkali feldspar granite and terminated soon after the emplacement of the porphyritic alkali feldspar granite in an extensional setting. These data indicated that there were extension-related magmatic activities accompanying ductile deformation in the southwestern part of the Korean Peninsula during 1.71–1.68 Ga. The Statherian extension-related events are well correlated with those in the midwestern part of the Korean and eastern parts of the North China Craton.

By autumn 1940 the first round of fighting in World War II was over. In northern Europe, German forces occupied Poland, Norway and Denmark. Both sides recognized that further operations demanded naval and air superiority in northern waters. Germany needed free access to the Atlantic Ocean through the North Sea; Britain had to prevent that access, which threatened the lifeline to the United States. More than ever before, it became essential for both sides to have meteorological information from the northern Atlantic Ocean area. Germany's need was especially acute, for the routes for her shipping from ports in Scandinavia traversed enemy-patrolled waters, where foul weather was essential for evasion.

During World War II, representatives of almost all the Soviet Republics fought in partisan detachments in the occupied territory of the Leningrad Region. Among them were many representatives of the Central Asian republics: Kazakhstan, Kyrgyzstan and Uzbekistan. Many Leningrad citizens, including relatives of partisans, had been evacuated to Central Asia by that time. However, representatives of Asian workers’ collectives came to meet with the partisans. The huge distance, the difference in cultures and even completely different weather conditions did not become an obstacle to those patriots-Turkestanis who joined the resistance forces in the North-West of Russia.

The history of England did not begin with the Industrial Revolution and not everything supposed about the Anglo-Saxons reduces to the myth of King Arthur and the Round Table. Contrary to commonly held beliefs, the Dark Ages of the North were full of splendor and brilliance; the only thing dark about them is their enshrouded history, but that only makes them all the more fascinating. The great burial mound at Sutton Hoo in East Anglia, discovered just before World War II, shines as one of the most grandiose sepulchers in history, yet the identity of its occupant remains a mystery. Was it a wealthy merchant, a warrior from overseas, or a great king? This paper gathers, presents, and scrutinizes the evidence and arguments from ancient records, opulate grave-goods, and contemporary investigations in an attempt to determine the most likely candidate for the individual interred in Mound 1 at Sutton Hoo.

The political challenge to the post-World War II order in shipping has been issued in the context of the North-South debate, but American power and interest are central to current developments. In the bulk and tanker sector the United States retains a strong interest in stability and successfully defends the existing order. In the liner sector, on the other hand, the United States has participated in recent assaults on the postwar order, producing great tension between Europe and America. There is a strong correlation between this growing maritime conflict and the political processes anticipated by the general theory of hegemonic stability. But “hegemony” and “power” are distinct concepts. Instability in international shipping arises neither from America's loss of power in shipping nor from challenges from Europe and the Third World. Rather, instability reflects American attempts to establish a closer identity between the existing regime and short-term national interest.

This chapter provides the mining history of the mountains of the rest of the world. It begins with England in which major silver discoveries took place in Bere Ferrers or Bere Ferris, a valley of the Tamar River in North Devon, southwest of Dartmoor, and at Combe Martin in the north after the mid-thirteenth century. However, English mines were challenging as they were physically distant from the central arteries of international trade of continental Europe and the commercial cities with continental catchment areas. This chapter also talks about silver mining that flourished in the Persian Province of Khorasan, the Samanid region of Transoxiana, and the Hindu Kush. These are the lands of the most spectacular mountain heights, where mountains piled up one behind another and mountain development assumes its grandest forms. It ends with mining history in India in which its mining exploits did not compete with the achievements of European mining regions. Mining in Zawar endured technical difficulties. Geologist Bagghi states that miners worked on hard siliceous quarzitic ore bodies, where drilling today calls for the use of tungsten carbide bits.

<p>Shallow water bodies dominate the areal extent of continental waters and host a proportion of biodiversity higher than the percentage of Earth’s surface they cover. <em>Daphnia</em> is a key component of small aquatic ecosystems food webs. Here we present the result of a survey in 24 ponds located in the core of Po river Basin, to assess the actual spreading of <em>Daphnia</em> species in one of the most productive areas of the Northern hemisphere. By using diagnostic genetic markers (<em>12S rRNA </em>and <em>ND5 </em>genes) we identified five <em>Daphnia</em> species: <em>D. ambigua</em>, <em>D. curvirostris</em>, <em>D. longispina</em>, <em>D. obtusa</em> and <em>D. pulex </em>in fourteen ponds. Additional analyses of two nuclear genes (<em>LdhA</em> and <em>Rab4</em>) revealed that <em>D. pulex</em> in the study area is native European strain. In opposite, <em>D. ambigua</em> shared haplotype with the North-Eastern American lineage that was introduced to Europe by long-distance dispersal. In the Po river Basin we identified a highly divergent lineage of <em>D. longispina </em>group that formed a clade with individuals from northern European Russia and might represent a new <em>Daphnia </em>species. <em>Daphnia</em> species in the Cremona province have European origin, except for <em>D. ambigua</em> which is a North American species spreading across Europe. Future attention will require monitoring of invasive species, particularly <em>D. ambigua</em> and the North American invasive clone of <em>D. pulex </em>that is already present in Northern Italy. </p>

Xavier Herbert published his bestseller Capricornia in 1938, following two periods spent in the Northern Territory. His next major work, Poor Fellow My Country (1975), was not published until thirty-seven years later, but was also set in the north during the 1930s. One significant difference between the two novels is that by 1975 photo-journalism had become a significant force for influencing public opinion and reforming Aboriginal policy. Herbert’s novel, centring upon Prindy as vulnerable Aboriginal child, marks a sea change in perceptions of Aboriginal people and their place in Australian society, and a radical shift toward use of photography as a means of revealing the violation of human rights after World War II. In this article I review Herbert’s visual narrative strategies in the context of debates about this key historical shift and the growing impact of photography in human rights campaigns. I argue that Poor Fellow My Country should be seen as a textual re-enactment, set in Herbert’s and the nation’s past, yet coloured by more recent social changes that were facilitated and communicated through the camera’s lens. Like all re-enactments, it is written in the past conditional: it asks, what if things had been different? It poses a profound challenge to the state project of scientific modernity that was the Northern Territory over the first decades of the twentieth century.

The aim of this anthropometric survey was to map regional differences in height and body proportions in eight counties adjacent to the Adriatic coast of Croatia. Body height was measured in 1803 males and 782 females aged 17-20 years at 66 schools in 23 towns. When corrected for population size, average male height in the eight counties is 182.6 cm (182.8 cm in seven counties of Adriatic Croatia and 183.7 cm in four counties of Dalmatia proper). Regional variation is considerable (3.5 cm): from 180.6 cm in the county of Karlovac to 184.1 cm in the county of Split-Dalmacija. The height of females in the eight counties is 168.2 cm (168.3 cm in Adriatic Croatia and 168.5 cm in Dalmatia proper), but it is based on more limited data. The results show that young men from Dalmatia are currently the tallest in the world in the age category of 18 years, and the north-to-south gradient of increasing stature on the Adriatic coast largely mirrors that in Bosnia and Herzegovina (BiH). These parallel changes of height in Croatia and BiH can most likely be explained by unique genetic predispositions that are shared by the local populations of the Dinaric Alps.

Background. The lithogeochemical features of fine-grained detrital rocks (mudstones, shales, and fine-grained siltstones) allow, with a certain degree of success, the main parameters of the formation of sedimentary sequences to be reconstructed. These parameters include (primarily in terms of their REE and Th systematics) the types of river systems supplying thin terrigenous suspension in the sedimentation area: the rivers of the 1st category – large rivers with a catchment area of more than 100,000 km2; 2nd category – rivers feeding on the products of erosion of sedimentary deposits; 3rd category – rivers draining mainly igneous and metamorphic rocks; and 4th category – rivers carrying erosion products of volcanic associations.Aim. To reveal, based on the analysis of interrelationships between such parameters as (La/Yb)N, Eu/Eu* and the Th content, the types of river systems that fed the Jurassic and Lower Cretaceous deposits of the Shaim oil and gas region (OGR) (Sherkalinsky, Tyumen, Abalak and Mulymya formations) and the region of the North Pokachevsky field of the Shirotnoe Priobye region (Sherkalinsky, Tyumen and Bazhenov formations, Lower Cretaceous deposits).Materials and methods. The ICP MS data for almost 100 samples of mudstones and fine-grained clayey siltstones were used to analyse the features of distribution of lanthanides and Th in the Jurassic and Lower Cretaceous clayey rocks of the Shaim OGR and the area of the North Pokachevsky deposits. Individual and average composition points for formations, members and layers were plotted on the (La/Yb)N-Eu/Eu*, (La/Yb)N–Th diagrams developed by us with classification areas of the composition of fine suspended material of modern rivers of different categories.Results and conclusion. The results presented in the article showed that during the formation of the deposits of the Shaim OGR in the Early and Middle Jurassic, erosion affected either mainly sedimentary formations or paleo-catchment areas that were very variegated in their rock composition. In the Late Jurassic, the source area was, most likely, a volcanic province, composed mainly of igneous rocks of the basic composition, and located within the Urals. This conclusion suggested that the transfer of clastic material from the Urals to the Urals part of the West Siberian basin “revived” much earlier than the Hauterivian. The Jurassic-Lower Cretaceous section of the vicinity of the North Pokachevsky field was almost entirely composed of thin aluminosilicaclastics formed due to the erosion of volcanic formations. These volcanic formations were located, as followed from the materials of earlier performed paleogeographic reconstructions, probably within the Altai-Sayan region or Northern Kazakhstan. Thus, the supply of detrital material in the considered territories of the West Siberian basin had a number of significant differences in the Jurassic and early Cretaceous.
