Examination of inclusions in minerals makes the basis for analyzing the peculiarities of salt crystallizationin the Kaliningrad-Gdansk halogen block of the Central- European evaporite basin. Most of the studied sections are composed of fine – medium- grained rock made of halite impregnated with polyhalite, kieserite, carnallite and kainite. Threesystemsofmicro-inclusionsmaybedistinguishedamongthe wide diversity of inclusions: 1) inclusions of mineral-forming mediums; 2) inclusions of surrounding mediums; 3) solid inclusions captured by minerals during their growth from marine solutions. Thedead-endpositionofthestudybasinaccounts for the solutions enrichment in potassium and magnesium arriving from the neighboring German-Polish halogen- bearing areas.

This article addresses a few archaeological finds from the earliest stage of the Great Migration Period (late fourth to the first half of the fifth century AD) in the territory of the Western Roman Empire related to Central Europe by origin, which could testify to the migration of the Vandals and the Suebi to the Roman West in 406 AD. These finds comprise different types of crossbow brooches discovered in the Roman provinces in Gallia, Spain, and North Africa, which parallels originate from the lands to the north of the Danube, in the zone where the Vandals and the Suebi lived by the moment of the migration to the West in 406 AD. Besides, some features of the funeral rite discovered in the early Great Migration Period in Eastern Gallia, particularly ritually destroyed weapons, meet with analogies in the cemeteries of Central European barbarians, particularly in the Przeworsk culture. These archaeological pieces of evidence were partially related to the arrival of the Vandals and the Suebi to the Roman Empire’s territory in 406 AD, and also reflected the presence of the Central European barbarians in the Roman military service.

The data has been given on the possible commercial potassium content of halogen sediments from the Pogozhskaya rhythmic member within the Western part of the North Caspian depression. It has been shown that the detailed lithological and geochemical studies, with the construction of the thickness maps, allow allocating in the section the most promising intervals with the potassium mineralization, as well as the taking into account the direction of nipping of the productive intervals and, as a consequence, choosing the priority of the sites for prospecting. Chloride type of potassium mineralization is represented by carnallites and sylvinites. The latter are the main source of the potassium ore. Sulfate salt — kainite and kieserite - are allocated only within the North-Western part of the basin. It has been found that the sylvinite layer was formed as a result of entering of the solutions with lower concentration (at the level of the halite stage) to the water basin with the strong brine of carnallite-bischofite stage . It has been revealed that the sylvite from the potash intervals of the section of the pogozhskaya rhythmic member is a product of the decomposition of carnallite.

This essay reads the novella Die Narrenburg (1844; “The Castle of Fools”), by the Austrian germanophone writer Adalbert Stifter (1805–68), in terms of colonial and postcolonial theory. I argue that Die Narrenburg captures the moment when race becomes visible in a multinational Austrian Empire figured as inner colonial space. The novella also offers a challenge to the reality of race emerging into visibility and presents a strikingly modern picture of divided colonial consciousness, its desires suspended melancholically between the symptomatic maintenance of imperialist identifications and a sensitivity to the colonized that anticipates Frantz Fanon. The text thus exposes Hapsburg Austria as an unexpected symbolic locus for thinking about European racial and colonial discourse. It serves as a perceptive theorist of race and colonialism in a broad sense and suggests how we might read other seemingly peripheral works of central European literature for insights into intra- and extra-European colonial contexts.

The high resolution STEM is now a fact of life. I think that we have, in the last few years, demonstrated that this instrument is capable of the same resolving power as a CEM but is sufficiently different in its imaging characteristics to offer some real advantages.It seems possible to prove in a quite general way that only a field emission source can give adequate intensity for the highest resolution^ and at the moment this means operating at ultra high vacuum levels. Our experience, however, is that neither the source nor the vacuum are difficult to manage and indeed are simpler than many other systems and substantially trouble-free.
