The magnesite deposits of North Evia, Lesvos and Chalkidiki, which are hosted by Alpine type ultramafic rocks, have been studied from an isotopie point of view and are compared with similar magnesite deposits occurring in other countries of central-southeastern Europe and Turkey. Magnesites from N. Evia, Lesvos and Chalkidiki have similar isotopie compositions. They have 513CPDB values ranging from -8.6 %o to -14.8 %o and 518OSMOW values ranging from 24.0 %oto 30.1 %o, which indicate a rather similar formation process for all three areas. The studied Greek magnesite deposits have similar isotopie compositions with vein and stockwork type magnesite deposits from: Turkey (Koyakci Tepe, vein and stockwork types; Helvacibaba, stockwork type), Poland (vein type), and Former Yugoslavia (vein type). There is strong isotopie evidence that meteoric water is involved in the formation of the stockwork and vein type magnesite deposits of all four countries, including Greece. There is also isotopie evidence for the organic origin of carbon participating in the carbonates (magnesites) of these deposits.

Of Greece

In the settlement of Greece after the Third Macedonian War Roman policy was at times moderate, at times harsh. On occasion the difference might represent only an individual point of view: thus the terms imposed upon Macedonia might seem generous to a Roman who contemplated the grant of ‘freedom’ to the Macedonians, the reduction of taxation and the absence of territorial aggression on Rome's part, while they might equally seem harsh to a Macedonian who felt that his sense of nationhood had been violated by Rome's creation of the four independent Republics. But towards Epirus Roman policy seems to have been marked by two successive stages, the first moderate, the second brutal. It is the purpose of this note to attempt to consider the causes which determined this change and to examine what influence the Epirote Charops exercised upon the measures which turned his country into a playground for Roman brutality and ultimately into an abomination of desolation.

The behavior of the oxygen-containing precipitate in silicon wafer on different stages of the getter formation process is considered from the mechanical point of view. The precipitate is modeled as a spheroidal inclusion undergoing inelastic eigenstrains in an anisotropic silicon matrix. The stress-strain state in the precipitate and matrix is calculated within the framework of the model. An energetic criterion of breaking the spherical shape by the coherent precipitates is obtained and analyzed. Criteria of the formation and onset of motion of the dislocation loops in the vicinity of the precipitate are also proposed. The obtained results are compared with the available experimental data.

Despite Greece being a global hotspot of subterranean biodiversity, its hypogean fauna is largely neglected from both an ecological and conservational point of view. An overview of the Niphargidae occurring in Greece is presented as an annotated list of all available published records. These records have resulted in an updated species list reflecting taxonomic corrections and species distribution range in the Greek peninsula. A total of 23 species, attributed to 3 genera, is up to date known from Greece with a high rate of endemicity found particularly in Crete. The endemic species of Greece amount to 21 (91% of total species richness), with the remaining species distributing also in the Republic of North Macedonia. Currently, none of them is listed in the national, European or global IUCN Red Lists of Threatened Species. Considering the increasing habitat degradation due to anthropic pressure, groundwater harvesting and climate change we could lose rare and endemic species without even acknowledging their existence.

Results of the study of the stable isotopes (δ18O, δD and δ13C) distribution in natural waters of the Baydar valley (southwestern part of the Crimean Peninsula) are presented. The study region holds fresh and ultra-fresh waters of predominantly bicarbonate calcium composition with TDS varying from 194 to 1137 mg/dm3. The research results revealed that all of the studied waters are of atmospheric origin that lie either along the global (GMWL) or local (LMWL) meteoric water lines. The established variations are: from -9.5 to -5.6‰ for δ18O values in waters with δD values varying from -64.0 to -40.0‰. The source for bicarbonate ion enriched in δ13C in natural waters of the Bauydar valley are carbonate sedimentary rocks, atmospheric carbon dioxide and organic compounds. Surface waters have heavier isotopic composition δ13C (-9.2 – -7.0‰) because of the atmospheric CO2. Artesian waters are differentiated by lighter δ13C (-12.8 – -10.7‰) due to the interactions between carbonate rocks and the dispersed organic matter. Water sources (springs, wells) are characterized by the widest variations of δ13C (-6.9 – -15.5‰) due to the presence of the atmospheric CO2 and intense processes of biochemical decomposition of organic compounds in the soil layer.

<p style="text-align: justify;">Stable isotope and elemental analyses were applied to the study of wines produced from the Cabernet Franc vine variety cultivated during several years (1982 to 1990) on specific parts of the Saumur-Champigny vineyard dedicated to the « terroir » experiment of INRA. The purpose of this work was to describe the behaviour or <sup>2</sup>H, <sup>13</sup>C and <sup>18</sup>O isotopes in the water and ethanol of wines in terms of the meteorological conditions (temperature, precipitation and insolation) which govern vine growing. Since the « terroir » concept involves a synergy between the c1imate and the soil, the distribution of typical metallic elements was also determined by flame and electrothermal ionization atomic absorption. About twenty parcels, carefully described from the geological and pedological point of view were considered in this study which demonstrated the ability of Sr, Al and Rb to discriminate between wines from the same year but grown on adjacent parcels. The content in trace elements of the wines was also shown to be correlated with the geological nature of the soil. As far as stable isotopes are considered, it appears that the climate of the year of production of a given region has a drastic influence on the isotope ratios of water and ethanol of wines and good correlations way be computed between these parameters and temperature and precipitations. From a more basic aspect, it is also shown that the nature of the soil which governs, at least in a part, the water use efficiency of vine, induces typical variations in the isotopic composition of wines. The results of this study demonstrate also the ability of stable isotope and elemental analyses to determine the geographical origin of a wine, and when the region of production is known, to infer the year of production from meteorological data. This method might prove to be an alternative method to radio carbon analysis for the next vintages.</p>

Antonio Cassese, who is now President of the International Criminal Tribunal for the Former Yugoslavia (ICTY), once observed from an academic point of view:[i]nternational legal control of warfare has kept pace with the developments in organized armed violence only to a limited extend. Major military Powers have not accepted sweeping restraints, with the consequence that this body of law is beset with deficiencies, loopholes, and ambiguity.

<p>The objective of this study is to describe the formation process of al Murabitun dynasty, and also discussing on the prosperity, the decrease, and the destruction of al Murabi tun dynasty. Al Murabitun dynasty was the unique dynasty as it was built based on the spirit of religiousity. And also the existance of the dynasty has been wellknown as it had wide area covering all of Africa and Spain. At the following time, the dynasty experienced the decrease after it had been lead by the third last king, until finally it faced the destruction period. The main cause of the down of the dynasty was a movement which was known as al-Muwahhidun dynasty. The destruction the dynasty caused by its poioer which was not in line with the attitude of tolerance of the society. The exploration on the spam of the dynasty will, then, strengthen our point of view on the ups and downs side dynasties in Islam as this is meaningful resource for Islamic scholars.</p><p> </p><p>Tujuan dari penelitian ini adalah untuk menggambarkan proses pembentukan dari dinasti al Murabitun, dan juga membahas tentang kemakmuran, yang menurun, dan penghancuran dinasti al Murabi tun. Al Murabitun<br />dinasti adalah dinasti yang unik karena dibangun berdasarkan semangat agama. Dan juga keberadaan dinasti telah diketahui dengan baik karena luasnya mencakup seluruh Afrika dan Spanyol. Pada waktu berikutnya, dinasti mengalami penurunan setelah itu dipimpin oleh raja terakhir ketiga, hingga akhirnya menghadapi periode penghancuran.<br />Penyebab utama turunnya dinasti adalah sebuah gerakan yang dikenal sebagai dinasti al-Muwahhidun. Penghancuran dinasti disebabkan pelopornya yang tidak sejalan dengan sikap toleransi dari masyarakat. Eksplorasi pada spam dari dinasti akan, kemudian, memperkuat sudut pandang kita pada dinamika sisi naik dan turun di Islam karena ini adalah sumber yang berarti bagi para ilmuwan Islam.</p>

This study was conducted in the districts of Kaeng Khoi and Muang, located in the center of Saraburiprovince, Central Thailand. The purpose was to use a stable isotope technique to iden-tify recharge areas where rainfall infiltrates. Analysis of stable isotopes in groundwater, surface water and rainwater were conducted in September 2014. Isotope compositions of groundwater were found to have δD values that ranged from -37.55‰ to -48.04‰ while δ18O values ranged from -5.30‰ to -7.34‰. The Local Meteoric Water Line (LMWL) in the study area was indis-tinguishablefrom the Bangkok Local Meteoric Water Line (BKK LMWL), and the stable iso-tope values of rainwater in area were more depleted than BKK LMWL. The isotope compo-sitions of surface water revealed that the effect of evaporation could divide the groundwater into two groups, with the first group locally receiving rainfall and the second group interacting directly with surface water. Therefore, care must be taken to prevent groundwater contamination in the latter group due to polluted surface water caused by human activities.
