One year of Ukraine’s De-communisation. A change in the historical narrative. OSW COMMENTARY NUMBER 211/16.05.2016

A year ago, the Parliament of Ukraine adopted four bills on the policy of national memory: on granting access to the archives of the repressive organs of the Communist totalitarian regime in the years 1917–1991, on the legal status and commemoration of Ukrainian independence fighters in the twentieth century, on the immortalisation of the victory over Nazism in the Second World War, 1939–1945, and on the condemnation of the Communist and National Socialist (Nazi) totalitarian regimes and the forbidding of their symbolism from being promoted. The laws came into force on 21 May 2015. After a year, it can be stated that only the latter two are being observed – the official narrative regarding World War II has been changed, mainly due to the activity of the Ukrainian Institute of National Remembrance (UINR), but also as a result of public statements by President Petro Poroshenko. The process of removing from public places the names and commemorations referring to the Soviet era is underway, and the fears that this may trigger serious conflicts have not proved true. From roughly a thousand placenames subject to de-communisation some two thirds have been changed so far (parliamentary bills regarding the remaining ones are awaiting approval) and most statues of Communist leaders have been removed. However, the law concerning independence fighters, which raised the most serious controversies, did not have any practical consequences. Moreover, nothing suggests that this could change. The implementation of the de-communisation laws is associated with a significant change in Ukrainian patriotic narrative: it is no longer focused on national martyrdom and it is beginning to emphasize heroic motives, which is in line with wartime needs. The fact that some of these motives are likely to trigger problems in Ukraine’s relations with Poland seems to be viewed as a marginal ‘by-product’.

Business under supervision – pathologies serving the system of power in Russia. OSW COMMENTARY NUMBER 212 | 31.05.2016

The relations between Russia’s authorities and business circles are subordinated not so much to rational economic calculations as to the interests of political elites. The key interest in this case is maintaining the current model of government. The formal and informal supervision of business by law enforcement agencies is an important element of Russia’s economic reality. Despite the rhetoric of high-ranking officials, intended to suggest that the state is taking care of businesspeople’s interests, it is evident that there is no will to devise a systemic solution to the most urgent problems, including the state institutions’ disrespect for the rights of ownership.

Cautious and rotational – US military engagement on NATO’s eastern flank. OSW Commentary NUMBER 216 | 05.07.2016

The Russian annexation of Crimea in 2014 put a stop to the gradual scaling down of US military engagement in Europe, a policy that the United States had pursued since the end of the Cold War. The Russian-Ukrainian conflict became a watershed for the US perceptions of European security as Washington started to see the threat of a conflict between Russia and a NATO member as more probable. The United States decided that – despite the mounting challenges in the Pacific region and its involvement in conflicts in the Middle East – it had to invest more in European security. The US has stepped up the intensity of joint drills with the allies and the activities of its forces in Europe. However, its support for the allies has been subject to various limitations and should be treated as a political signal to Moscow, rather than an element in a broader strategy. The future of the policy of strengthening the eastern flank will depend on the outcome of the US presidential elections in November and on developments in the bilateral relations between Washington and Moscow.

Chromatographic fractionation of bitumen from sediments and presence of glycerol ethers in immature sediments (Table 2)

Alkanes having unusual saturated isoprenoidal and methyl-branched structures have been isolated from the bitumen of several sediments. The methanogenic biomarkers 2,6,10,15,19-pentamethyleicosane and squalane were found in sediments which also contained bacteriogenic glycerol ethers. However, in one ether-containing sediment, 2,6,10,13,17,21-hexamethyldocosane was tentatively identified and this compound was found in place of the established alkane biomarkers. Other hydrocarbons found were regular C21 and C23 isoprenoid alkanes, compounds which cannot be derived from phytol; two isoprenoids of the type 3,7,11.-polymethylalkane, previously reported only in petroleums; 8-methylheptadecane, a probable biomarker for cyanobacteria and a number of its homologs and other methyl-branched alkanes. Ubiquitous branched-chain alkylbenzenes and a homology of trimethylalkylbenzenes were also isolated. Most, or all, of the compounds reported here are probably not catagenetic products but may represent direct algal or bacterial bioinputs.

Benthic foraminiferal number of specimens in Cretaceous samples of various DSDP and ODP Sites (Table 2)

Benthic foraminifera from 24 DSDP/ODP sites were investigated to assess their global horizontal and vertical distribution in the deep-sea environment at the end of the Cretaceous period. The samples analyzed are from the late Maastrichtian and within the planktic foraminiferal Abathomphus mayaroensis Zone from a wide range of oceans and paleolatitudes, including the low-latitude Sites 10 and 384 (Atlantic Ocean), 47, 171, 305, and 465 (Pacific Ocean), the mid-latitude Sites 20, 111, 356, 363, 516, 525, 527, 548, and 605 (Atlantic Ocean), 216, 217, and 758 (Indian Ocean), and the high-latitude Sites 208 (Pacific Ocean), 689,698,700,738 and 750 (Southern Ocean). Correspondence analysis, based on the 75 most common taxa, shows a clear biogeographic trend along the first correspondence axis by arranging the sites in paleolatitudinal order. The assemblages from the Tethyan Realm (i.e., low latitudes) are marked by abundant heavily calcified buliminids (such as Bulimina incisa, B. trinitatensis, B. velascoensis, and Reussella szajnochae) and Aragonia spp., whereas high-latitude faunas are characterized by abundant Alabamina creta, Gyroidinoides quadratus, and Pullenia coryelli. The results indicate that the faunas at low and high latitudes, respectively, were influenced by quite different environmental conditions. This is based on the much higher abundance of infaunal morphotypes at low and mid latitudes compared to high latitudes, suggesting that the biogeographic trend found in the data set coincides with the trophic regime at the various sites. The results also provide support for the hypothesis that postulates two simultaneous sources and mechanisms for deep-water formation during the Late Cretaceous, including warm, saline deep water produced by evaporation at low (equatorial) latitudes in contrast to the formation of cold deep waters at high (southern) latitudes.

(Table 1) Summary of basalt unit thickness, vesicularity, number of flow units, and average porosity at ODP Site 135-839

An inflatable drill-string packer was used at Site 839 to measure the bulk in-situ permeability within basalts cored in Hole 839B. The packer was inflated at two depths, 398.2 and 326.9 mbsf; all on-board information indicated that the packer mechanically closed off the borehole, although apparently the packer hydraulically sealed the borehole only at 398.2 mbsf. Two pulse tests were run at each depth, two constant-rate injection tests were run at the first set, and four were run at the second. Of these, only the constant-rate injection tests at the first set yielded a permeability, calculated as ranging from 1 to 5 * 10**-12 m**2. Pulse tests and constant-rate injection tests for the second set did not yield valid data. The measured permeability is an upper limit; if the packer leaked during the experiments, the basalt would be less permeable. In comparison, permeabilities measured at other Deep Sea Drilling Project and Ocean Drilling Program sites in pillow basalts and flows similar to those measured in Hole 839B are mainly about 10**-13 to 10**-14 m**2. Thus, if our results are valid, the basalts at Site 839 are more permeable than ocean-floor basalts investigated elsewhere. Based on other supporting evidence, we consider these results to be a valid measure of the permeability of the basalts. Temperature data and the geochemical and geotechnical properties of the drilled sediments all indicate that the site is strongly affected by fluid flow. The heat flow is very much less than expected in young oceanic basalts, probably a result of rapid fluid circulation through the crust. The geochemistry of pore fluids is similar to that of seawater, indicating seawater flow through the sediments, and sediments are uniformly underconsolidated for their burial depth, again indicating probable fluid flow. The basalts are highly vesicular. However, the vesicularity can only account for part of the average porosity measured on the neutron porosity well log; the remainder of the measured porosity is likely present as voids and fractures within and between thin-bedded basalts. Core samples, together with porosity, density, and resistivity well-log data show locations where the basalt section is thin bedded and probably has from 15% to 35% void and fracture porosity. Thus, the measured permeability seems reasonable with respect to the high measured porosity. Much of the fluid flow at Site 839 could be directed through highly porous and permeable zones within and between the basalt flows and in the sediment layer just above the basalt. Thus, the permeability measurements give an indication of where and how fluid flow may occur within the oceanic crust of the Lau Basin.

Authorities agree that the first part of the work, published in Paris 1684, was written by Marana. The remainder has been ascribed to different Englishmen, among them Dr. Robert Midgley and William Bradshaw. It is probable however that Midgley simply edited the English translation, made by Bradshaw, of the original Italian manuscript. cf. ESTC.

Molecular characterization of the microbial species that colonize human ileal and colonic mucosa by using 16S rDNA sequence analysis

Aim: The aim of this study was to characterize the bacterial community adhering to the mucosa of the terminal ileum, and proximal and distal colon of the human digestive tract. Methods and Results: Pinch samples of the terminal ileum, proximal and distal colon were taken from a healthy 35-year-old, and a 68-year-old subject with mild diverticulosis. The 16S rDNA genes were amplified using a low number of PCR cycles, cloned, and sequenced. In total, 361 sequences were obtained comprising 70 operational taxonomic units (OTU), with a calculated coverage of 82.6%. Twenty-three per cent of OTU were common to the terminal ileum, proximal colon and distal colon, but 14% OTU were only found in the terminal ileum, and 43% were only associated with the proximal or distal colon. The most frequently represented clones were from the Clostridium group XIVa (24.7%), and the Bacteroidetes (Cytophaga-Flavobacteria-Bacteroides ) cluster (27.7%). Conclusion: Comparison of 16S rDNA clone libraries of the hindgut across mammalian species confirms that the distribution of phylogenetic groups is similar irrespective of the host species. Lesser site-related differences within groups or clusters of organisms, are probable. Significance and Impact: This study provides further evidence of the distribution of the bacteria on the mucosal surfaces of the human hindgut. Data contribute to the benchmarking of the microbial composition of the human digestive tract.

A census of critical sets in the Latin squares of order at most six

A critical set in a Latin square of order n is a set of entries from the square which can be embedded in precisely one Latin square of order n, Such that if any element of the critical set. is deleted, the remaining set can be embedded, in more than one Latin square of order n.. In this paper we find all the critical sets of different sizes in the Latin squares of order at most six. We count the number of main and isotopy classes of these critical sets and classify critical sets from the main classes into various strengths. Some observations are made about the relationship between the numbers of classes, particularly in the 6 x 6 case. Finally some examples are given of each type of critical set.
