The international law implications of the Turkish/Kurdish conflict

This article considers the threaties and customs governing armed conflict in the context of the long standing insurgency in southeast Turkey. The first part of the article analyzes the existing treaty and customary law concerning the threshold of an armed conflict and concludes that the insurgency in Southeast Turkey existing since 1984 rises to the level of an armed conflict based on criteria identified both in treaty and customary international law. The next consideration is the classification of this conflict and this part concludes that this situation is a non-international armed conflict due to lack of involvement of forces of another country. Finally, this article considers international humanitarian law applicable to this non-international armed conflict and reveals that as a result of the monumental International Committee of the Red Cross customary humanitarian law study, particularly with respect to the law of targeting, that the rules applicable to international and non-international armed conflict have never been closer.

Arthur et ses barons rebelles: la fin remaniée et abrégée de la Suite Vulgate dans le manuscrit du cycle du Graal, Paris, BNF fr. 344

The ms. Paris, BnF, fr. 344 was produced in Lorraine at the end of the thirteenth century and contains the whole Lancelot-Grail cycle. It presents an abridged version of the end of the Vulgate Sequel to Merlin. The rewriting of the end of the sequel glosses over the romantic episodes of the common version and focuses on the figure of Arthur, a legitimate sovereign and skilful war leader confronted by his barons’ dissidence. From the end of f° 182 to f° 184v°, BnF, fr. 344, narrates the departure of Kings Ban and Bohort for the Continent, the embassy of King Loth and his sons, and the fight against the Saxons of the Christian coalition gathered at Logres for the feast of the Holy Cross. This article shows the ideological implications of the abridgement and the illustration used at the end of the Vulgate Sequel in ms. fr. 344, as it exalts Arthur’s kingship and insists on the rallying, penance and submission of his rebelled vassals.

Higher oxides of chlorine: absorption cross-sections of Cl2O6 and Cl2O4, the decomposition of Cl2O6, and the reactions of OClO with O and O-3

The absorption cross-sections of Cl2O6 and Cl2O4 have been obtained using a fast flow reactor with a diode array spectrometer (DAS) detection system. The absorption cross-sections at the wavelengths of maximum absorption (lambda(max)) determined in this study are those of Cl2O6: (1.47 +/- 0.15) x 10(-17) cm(2) molecule(-1), at lambda(max) = 276 nm and T = 298 K; and Cl2O4: (9.0 +/- 2.0) x 10(-19) cm(2) molecule(-1), at lambda(max) = 234 nm and T = 298 K. Errors quoted are two standard deviations together with estimates of the systematic error. The shapes of the absorption spectra were obtained over the wavelength range 200-450 nm for Cl2O6 and 200-350 nm for Cl2O4, and were normalized to the absolute cross-sections obtained at lambda(max) for each oxide, and are presented at 1 nm intervals. These data are discussed in relation to previous measurements. The reaction of O with OCIO has been investigated with the objective of observing transient spectroscopic absorptions. A transient absorption was seen, and the possibility is explored of identifying the species with the elusive sym-ClO3 or ClO4, both of which have been characterized in matrices, but not in the gas-phase. The photolysis of OCIO was also re-examined, with emphasis being placed on the products of reaction. UV absorptions attributable to one of the isomers of the ClO dimer, chloryl chloride (ClClO2) were observed; some Cl2O4 was also found at long photolysis times, when much of the ClClO2 had itself been photolysed. We suggest that reports of Cl2O6 formation in previous studies could be a consequence of a mistaken identification. At low temperatures, the photolysis of OCIO leads to the formation of Cl2O3 as a result of the addition of the ClO primary product to OCIO. ClClO2 also appears to be one product of the reaction between O-3 and OCIO, especially when the reaction occurs under explosive conditions. We studied the kinetics of the non-explosive process using a stopped-flow technique, and suggest a value for the room-temperature rate coefficient of (4.6 +/- 0.9) x 10(-19) cm(3) molecule(-1) s(-1) (limit quoted is 2sigma random errors). The photochemical and thermal decomposition of Cl2O6 is described in this paper. For photolysis at k = 254 nm, the removal of Cl2O6 is not accompanied by the build up of any other strong absorber. The implications of the results are either that the photolysis of Cl2O6 produces Cl-2 directly, or that the initial photofragments are converted rapidly to Cl-2. In the thermal decomposition of Cl2O6, Cl2O4 was shown to be a product of reaction, although not necessarily the major one. The kinetics of decomposition were investigated using the stopped-flow technique. At relatively high [OCIO] present in the system, the decay kinetics obeyed a first-order law, with a limiting first-order rate coefficient of 0.002 s(-1). (C) 2004 Elsevier B.V. All rights reserved.

X-ray scattering study of the effect of hydration on the cross-beta structure of amyloid fibrils

We have investigated the effect of sample hydration on the wide-angle X-ray scattering patterns of amyloid fibrils from two different sources, hen egg white lysozyme (HEWL) and an 11-residue peptide taken from the sequence of transthyretin (TTR105-115). Both samples show an inter-strand reflection at 4.7 Å and an inter-sheet reflection which occurs at 8.8 and 10 Å for TTR105-115 and HEWL fibrils, respectively. The positions, widths, and relative intensities of these reflections are conserved in patterns obtained from dried stalks and hydrated samples over a range of fibril concentrations. In 2D scattering patterns obtained from flow-aligned hydrated samples, the inter-strand and inter-sheet reflections showed, respectively, axial and equatorial alignment relative to the fibril axis, characteristic of the cross-β structure. Our results show that the cross-β structure of the fibrils is not a product of the dehydrating conditions typically employed to produce aligned samples, but is conserved in individual fibrils in hydrated samples under dilute conditions comparable to those associated with other biophysical and spectroscopic techniques. This suggests a structure consisting of a stack of two or more sheets whose interfaces are inaccessible to bulk water.

A study of the atmospherically relevant reaction between molecular chlorine and dimethylsulfide (DMS): establishing the reaction intermediate and measurement of absolute photoionization cross-sections

In a study using UV photoelectron spectroscopy (PES) of the atmospherically relevant reaction CH3SCH3 + Cl2 → CH3SCH2Cl + HCl bands associated with a reaction intermediate have been observed. These have been assigned to ionization of the covalently bound molecule (CH3)2SCl2 on the basis of the intensity of the observed bands as a function of reaction time, molecular orbital calculations of vertical ionization energies and evidence from infrared spectroscopy. A method has also been developed, with the flow-tube/PE spectrometer combination used, to measure photoionization cross-sections of the reagents and products at the photon energy utilized and this has allowed the photoionization cross-section of the intermediate to be estimated. This work augments an earlier study in which the rate constant of the reaction between CH3SCH3 (DMS) and Cl2 has been measured at room temperature.

An analysis of the determinants of cross-border real estate development flows

This paper investigates the scale and drivers of cross-border real estate development in western and central and eastern Europe (CEE). Drawing upon existing literature on the integration of international real estate markets, we make some inferences on expected patterns of cross-border real estate development from this literature review. The paper draws upon a transactions database in order to assess the penetration of national markets by international real estate developers. The determinants of cross-border transaction flows are modeled as a function the range of economic and real estate variables. Whilst western European markets tend to be dominated by local developers, much higher levels of market penetration by international real estate developers are found in the less mature markets of central and eastern Europe. Empirical modelling based on gravity model specifications reveal the importance of size of the economies, distance between countries, extent of globalization and EU membership as significant determinants of cross-border real estate development flow.

The Byzantine Church of the Nutrition in Nazareth rediscovered

Although Nazareth has usually been seen by scholars as a relatively minor Byzantine pilgrimage centre, it contained perhaps the most important ‘lost’ Byzantine church in the Holy Land, the Church of the Nutrition ‐ according to De Locis Sanctis built over the house where it was believed that Jesus Christ had been a child. This article, part of a series of final interim reports of the PEF-funded ‘Nazareth Archaeological Project’, presents evidence that this church has been discovered at the present Sisters of Nazareth convent in central Nazareth. The scale of the church and its surrounding structures suggests that Nazareth was a much larger, and more important, centre for Byzantine-period pilgrimage than previously supposed. The church was used in the Crusader period, after a phase of desertion, prior to destruction by fire, probably in the 13th century.
