Several specimens of Lauraceae fossil wood from the Cenozoic of Greece (southern part of Lesbos), the Czech Republic (Kadaň-Zadní Vrch Hill and Jáchymov), and Hungary (Ipolytarnóc) were studied. When considering whether they belonged to the speciose fossil wood genus Laurinoxylon, we reviewed the literature and data from InsideWood on fossil and modern woods. As a result, we propose criteria for excluding a fossil Lauraceae wood from Laurinoxylon and list the species that should be excluded from this genus. The criteria (filters) proposed to exclude a genus from having relationships with Laurinoxylon are: A. Axial parenchyma features: A1. Marginal axial parenchyma, A2. Aliform to aliform-confluent paratracheal parenchyma. B. Ray features: B1. Rays higher than 1 mm, B2. Exclusively homocellular rays, B3. Rays more than 5 cells wide, B4. Rays storied. C. Porosity features: Ring-porous. D. Idioblasts: Absence of idioblasts. Based on the distribution of idioblasts, we recognize four groups in Laurinoxylon (Type 1 - with idioblasts associated only with ray parenchyma cells, Type 2a - with idioblasts associated with both ray and axial parenchyma, Type 2b - with idioblasts associated both with rays and present among the fibres, and Type 3 - with idioblasts associated with ray and axial parenchyma and also among the fibres) and list the extant genera with features of those groups. Such grouping helps with interpreting the relationships of fossil lauraceous woods with extant genera. We discuss the Oligocene–Miocene European species that belong to these Laurinoxylon groups, noting that some warrant reassignment to different genera or even families. Future studies are needed to determine whether new genera should be established to accommodate these species. We propose the new combination Cinnamomoxylon variabile (Privé-Gill & Pelletier) Mantzouka, Karakitsios, Sakala & Wheeler.

In this research, the estimation of the fatigue life of a semi-submersible floating offshore wind platform is considered. In order to accurately estimate the fatigue life of a platform, coupled aerodynamic-hydrodynamic simulations are performed to obtain dynamic stress values. The simulations are performed at a multitude of representative environmental states, or “bins,” which can mimic the conditions the structure may endure at a given site, per ABS Floating Offshore Wind Turbine Installation guidelines. To accurately represent the variety of wind and wave conditions, the number of environmental states can be of the order of 103. Unlike other offshore structures, both the wind and wave conditions must be accounted for, which are generally considered independent parameters, drastically increasing the number of states. The stress timeseries from these simulations can be used to estimate the damage at a particular location on the structure by using commonly accepted methods, such as the rainflow counting algorithm. The damage due to either the winds or the waves can be estimated by using a frequency decomposition of the stress timeseries. In this paper, a similar decoupled approach is used to attempt to recover the damages induced from these coupled simulations. Although it is well-known that a coupled, aero-hydro analysis is necessary in order to accurately simulate the nonlinear rigid-body motions of the platform, it is less clear if the same statement could be made about the fatigue properties of the platform. In one approach, the fatigue damage equivalent load is calculated independently from both scatter diagrams of the waves and a rose diagram of the wind. De-coupled simulations are performed to estimate the response at an all-encompassing range of environmental conditions. A database of responses based on these environmental conditions is constructed. The likelihood of occurrence at a case-study site is used to compare the damage equivalent from the coupled simulations. The OC5 platform in the Borssele wind farm zone is used as a case-study and the damage equivalent load from the de-coupled methods are compared to those from the coupled analysis in order to assess these methodologies.

The aim of this study was to gather information on the spread of antibiotic resistance in Escherichia coli isolates from wells, boreholes and untreated drinking water in islands of Greece. We analyzed for antibiotic resistance 235 E. coli strains isolated from untreated drinking water of small rural communities, and ground water from 4 islands. Resistance was tested against Norfloxacin, Ciprofloxacin, Levofloxacin, Amoxicillin and Cefaclor. More than half (54.9%) were resistant to at least one of the antibiotics tested. Of these 26.3% showed multiple resistance (to two or more antibiotics). Strains from drinking water sources were overall more sensitive. Frequent resistance was observed for Amoxicillin (38.3%) and Levofloxacin (28.5%), low for Norfloxacin (5.5%).

Interest in the history of book collections is not a recent phenomenon. However, rapid development of computers and the Internet over the past twenty years has provided researchers with new tools for network analysis, such as UCI6 и NetDraw 2.160. Continuing to identify the provenance of the documents kept in the Western European Section of the Scientific Historical Archive of the St. Petersburg Institute of History of the Russian Academy of Sciences, the author had to face the fact that abundance of information and complexity of the links between various sources make it difficult to make out the complete picture. The Western European section of the Scientific Historical Archive of the St. Petersburg Institute of History of the Russian Academy of Sciences is mostly based on the collection of the academician N P. Likhachev (1862—1936). N.P. Likhachev contacted hundreds of antiquarian firms around the world, and thus his collection fits into the complex and interwoven system of the European antiquarian market of the late 19th–early 20th century. To overcome the problem of branching data, the author decided to call on the experience of sociologists and to use computer programs for network analysis that enable to reflect and comprehend the links between objects. The article is to present the process and results of this work, as well as to underscore problems and specificity of the programs in relation to the archival material. The main source is data from the personal provenance archive of the academician N. P. Likhachev, collection of documents on the history of the Western European Section, and artifacts from the Likhachev collection. The second layer of sources is antiquarian catalogs. The program can visualize these two layers of information in different ways by using different colors and lines. Overlaying of the schemes allows completing of missing elements in the chain of provenance. It should be noted that due to the richness of the sources, the network, originally compiled for the collection of N.P. Likhachev, grows into a pan-European system of “collector-antiquarian” relationships. It opens wide perspectives for research.

This paper proposed to discuss the socio-environmental conditions of women at prison in Karachi.1 Prison is kind of punishment in which people are physically restricted of a range of personal freedom. Besides this, in jail manual, women have been protected by different rules and regulations. This paper is an explanatory study based on quantitative and qualitative research methodology. The questionnaire method was used for the purpose of data collection. The study shows that the situation on ground and the conditions of women prisoners is not good. In Pakistan rules and laws are available however, they are not implemented. This paper also suggests measures and recommendations in order to overcome the unhealthy and unhygienic condition faced by women prisoners at Karachi Central Jail.

This chapter discusses Marshal Tito's plan to take the whole of the Balkans, which failed before it even started to materialize due to the disintegration of the Communist Party of Greece (KKE). It details how the KKE survived the repression carried out by dictator Ioannis Metaxas between 1936 and 1941 and fell apart completely in 1940, when Italy invaded Greece from Albanian soil. It also describes the faction of the Bulgarians that became dominant in the KKE when the German armies entered Greece after having overrun Yugoslavia in their Balkan onslaught. The chapter discusses how the Molotov–Ribbentrop Pact secured the position of the Bulgarian communists as collaborationists. It mentions Metodij Šatorov, a man installed into the Communist Party of Yugoslavia leadership for Macedonia by Georgi Dimitrov that detached the Skopje-based Regional Committee from the CPY and attached it to the Bulgarian Communist Party.
