5-Bromo-2'-deoxyuridine triphosphate (Br-dUTP) and dTTP are used interchangeably for DNA synthesis in vitro by the Klenow fragment of Escherichia coli DNA polymerase I. When DNA containing Br-dUMP instead of dTMP at a few preselected sites is transfected into competent bacteria, no mutation occurs, indicating that in vivo E. coli DNA polymerase always places a dAMP residue in front of any unrepaired Br-dUMP residue. On the other hand, in vitro Br-dUTP can also replace dCTP, but only with difficulty: when dCTP is absent, Br-dUMP can be forced in front of a dGMP residue, but the Klenow polymerase pauses before and after addition of Br-dUMP. Transfection into E. coli of the substituted DNA leads to the expected G----A transitions. These mutations can easily be targeted by using a suitable primer and the correctly chosen mix of deoxynucleoside triphosphates containing Br-dUTP. When Br-dUMP has been placed in front of a dGMP residue, the mutation yield is not 100%, showing a partial repair of the transfected DNA before it is replicated. Advantage can be taken of this partial repair to prepare a set of different mutations within a target region in a single experiment. [less ▲]

The Peace of Fexhe has always been seen by the Liegeois as a constitutional treaty of paramount importance as it provided the principality of Liège with a representative assembly. Yet, this text, enacted in 1316, remained in use until the end of the State of Liège. The present article focuses therefore on its history in order to determine the role it actually played in the political life of Liège at the end of the Middle Ages and during the Modern Times. What emerges is that, signed in a context of tension, the Peace of Fexhe really was a compromise signed between two parties exhausted by famine, not the victory of one over the other. Even though the treaty seems to record several claims of the opponents to the prince-bishop Adolphe de La Marck, it really is the latter who, in spite of what numerous historians believed, continued to direct the political game of Liège. Indeed, his arbitrators managed to counter the claims of their opponents through the insertion of clauses preventing any real upheaval within the principality. For Adolphe, this treaty is therefore a break in his quest for a total sovereignty. Following him, the prince-bishops of Liège strove in defence of their power, contravening if need be the text of 1316. The Liégeois appeared to us to have been perfectly aware of the limits of the Peace of Fexhe but they endeavoured to gloss over these in order to make the text an absolute reference in the domain of political claims and a revered rallying symbol. Then, it will be through the constant reminder of this treaty that various political claims arose, making it de facto the source of the “Liegian constitution”. Afterwards, the Liegeois had recourse to the Peace of Fexhe in order to legitimate their political options. However, it was absolutely not a general rule since several politicians close to the people, such as Thierry de Perwez or Raes de Heers did not make use of the text. On the contrary, it was within more “cultivated” circles, such as the municipal magistrates and the burgomasters, that the text was the less rarely used, whether it be at the time of the promulgation of the decisions of the Council of Trente or at the eve of the Liegian Revolution. Moreover, it is by its almost uninterrupted presence in the Liegian politics that the Peace of Fexhe asks the question of the administration of law in the principality. In spite of a common objective, punishing the abuse of power of the episcopal officers, it was in opposition over the question of the procedure with the Peaces of the XXII . Yet the Court of the XXII considered itself to be in charge of the defence of the Peace of Fexhe. Similarly, the capitulations of the prince-bishops swore to the respect of the text and court without fear of a contradiction that no one seemed to have wanted to highlight. This shows how deep it was rooted in the Liegian legal culture, even though the real action of the Peace of Fexhe through the centuries left few traces. In conclusion, the Peace of Fexhe owes its prestige to its recuperation by different political forces that used it as a battle flag, adapting it, contradicting it sometimes, to their claims. Thus, event though its exact stipulations were forgotten as soon as the end of the 16th century and it was then progressively completed, it survived in the imagination and built up its prestige on the additional meaning its utilisations provided it with, for, in Liège, who defends Fexhe defends the good right.

The Himmelbaach quarry is located in the Wiltz Synclinorium in Luxembourg. The rocks outcropping in this quarry correspond to the mid-Emsian Clervaux Shales Formation. Three different facies have been identified in the quarry. An argillaceous sandstone facies with oblique stratifications, cross-stratifications, herring-bones and erosive bases represent the first facies; the second facies is characterized by lenticular- (with connected lenses) to wavy-bedded sandy argillites, argillaceous sandstones and quartz arenites. The last facies corresponds to a quartz arenite with oblique stratification, planar laminations and mud drapes. The base of this facies shows flaser bedding and sigmoidally curved bed surfaces. The palaeoenvironmental study of this area is rather difficult because of the structural deformation and lateral variation of the facies. Due to this deformation, six partial sections (4a to 4f) were sampled here. In order to reconstruct a reliable vertical and lateral succession of the depositional setting, facies analysis and magnetic susceptibility were used. Magnetic susceptibility (MS) is generally applied as a tool for correlation in a deepwater carbonated environment. In this paper we used the MS technique successfully in a siliciclastic proximal setting. Analysis of MS curves as well as the recognition of three marker beds ((1) the last bed of argillaceous sandstones in Facies 1; (2) a thin horizon of carbonated sandstone within Facies 2; (3) the first appearance of the characteristics massive quartzitic beds in Facies 3) allowed the correlation of sections 4a, 4b and 4c. These correlations helped us to reconstruct a vertical and lateral succession of facies, which ultimately led to the recognition of a tide-dominated marginal-marine depositional model composed respectively of tidal channels (Facies 1), a tidal flat (Facies 2) and a tidal sand ridge (Facies 3). This example also shows the usefulness of magnetic susceptibility for small scale correlation, even in a proximal environment such as a marginal-marine setting. [less ▲]

A list of Devonian vertebrates from the Luga District of the Leningrad Region (Russia) was originally mentioned by P. N. Venyukov (1884). However, detailed palaeoichthyological studies in this territory started in only during 1926-1931 in the framework of the geological mapping programme. Two field crews studied the sections of the Middle and Upper Devonian by the Luga, Lemovzha, Oredezh, Tesovaya and Vruda rivers. One of the teams was the Devonian Lithological expedition under guided by R. F. Hecher. D. V. Obruchev was also involved in the works of this expedition. Other team headed by B. P. Asatkin surveyed the western part of the Leningrad Region. Both teams sampled numerous outcrops and boreholes, and collected abundant vertebrate remains. As a result the Devonian deposits were subdivided into the regional beds characterized by diverse vertebrate assemblages. Collectioning and research of Devonian vertebrates in this area continued in the 1950-1960ties by D. V. Obruchev and his students: V. N. Karatajute-Talimaa, E. Mark-Kurik, L. A. Lyarskaya. Their descriptions of Eifelian-Frasnian agnathans and fishes were published in the series of monographs or papers (e.g. Karatajute-Talimaa, 1963, Obruchev & Mark-Kurik, 1965, Lyarskaya, 1981). During the last thirty years J. Valiukevicius and some of the authors of the present report supplemented the vertebrate collections from some sections. The new localities in this area were reported by the 2001 Latvian-Russian Expedition (A. Ivanov, E. Luksevics, I. Zupins and others). The 2009-2010 Russo-Franco-Latvian expedition discovered a new diverse material from the historical and new localities of that area. [less ▲]

Palynological samples from two boreholes drilled in the eastern part of Saudi Arabia contain a rich assemblage of cryptospores and trilete spores. They are dated as most probably Lochkovian in age. Intriguingly, the cryptospores are very similar to those from a coeval continental palynomorph assemblage from the Old Red Sandstone Continent, whereas the trilete spores show a strong affinity with miospore assemblages from Western Gondwana. It is suggested that cryptospore-producing plants inhabited confined, damp biotopes and had a wide range of climatic tolerance. On the otherhand, trilete spore-producing plants inhabited a wider variety of biotopes but were more sensitive to climatic variations. The high degree of similarity between Old Red Sandstone and Saudi Arabian cryptospore assemblages favours palaeogeographic reconstructions where there is close proximity between Western Gondwana and Euramerica and/or a land connection between these palaeoplates. Climatic differences between the Old Red Sandstone Continent and the northern part of Western Gondwana can be invoked to explain the variations in the trilete spore assemblages.
