The Right

The basic concept of balanced and healthy nutrition depends on the consumption of right foods at the right amounts. The nutrient of foods is affected by variable factors such as geographical and ecological characteristics, harvest time, processing and transportation, storage, and consumption conditions. High qualified instrumental analyses techniques should be done while the determination of the nutrient levels. Because, the quality of results of the analysis are the most important criterion in creating food composition tables, the database and data sets. In this study, the basic nutrient composition of some economic marine fish was determined. For this, fish were collected from the Black Sea and the Marmara Sea was composites formed from the fish flesh separately for each region. Then, moisture, ash, fat, protein, fatty acids composition, and cholesterol levels were examined with the composites. While the average values were obtained according to the results of the analysis, differences among regions were examined. While the fat content in anchovy, bluefish, bonito, and barbatus is above %10 g/100g, in whiting was approximate %1. Average EPA and DHA values in anchovy are %15,86 and %17,01 respectively. The highest cholesterol was obtained in whiting as around 77 mg/100g.

Unlike other seas of the world, the Black Sea shows unique quality and trophic properties. Fortunately, only the upper layer water of the Black Sea is introduced into the Bosphorus and has a significant effect on the quality and trophic conditions of the Marmara Sea. These effects are discussed in the light of data obtained from collaborative efforts of Turkish and Romanian research institutions and processed satellite images. In conjunction with these discussions, recommendations for a suitable effluent disposal strategy for Istanbul's wastewater have been given.

Set Up

A modelling study of the hydrodynamics and spreading of wastewater from existing and future outfalls in the Bosphorus region has been conducted applying a 3-Dimensional model. The modelling is based on SYSTEM 3, which is a general modelling system for baroclinic flow simulating unsteady currents, waterlevels, salinity and temperature within the model area. The model set-up covers the Black Sea-Bosphorus-Marmara Sea junction area. The set-up is calibrated by data from a dedicated field program and previous field experience. The model is designed to describe the characteristic features of the flow in the junction area such as the effects of variations in waterlevel differences between the Sea of Marmara and the Black Sea on the important two-layer structure in the strait and the flow fields generated by the upper layer jet in the Bosphorus-Marmara junction. This model has been applied for evaluation of disposal of wastewater and for the subsequent water quality studies. The general use of a baroclinic 3-D hydrodynamic model to simulate disposal of wastewater is discussed. Examples of the application of the model of the junction area to evaluate the different strategies for disposal of wastewater are presented.

The article presents an analysis of scientific heritage of the biologist Antoni Andrzejowski (1785–1869), whose name is well known in Ukraine and abroad as a naturalist and a scientist. Antoni Andrzejowski had been cooperating with V. Besser for many years and accompanied him in his trips, he was the first botanist in Kremenets that was born in Volyn, and, at the same time, the first who graduated from the Kremenets Lyceum. His contribution to botanical, zoological, palaeontological, and geological sciences is also recognised, in particular he authored the first geological map of Podillia. The scientist is known primarily for pioneering research on plant diversity: together with W. Besser, he initiated the floristic study of Volyno-Podillia and the Right-Bank Ukraine. He was a traveller, a researcher of the flora, fauna (both modern and fossil) and geology of Podillia, Polissia, the Dnieper, and the Black Sea, as well as the author of a number of original scientific works. During his numerous trips, he collected a variety of scientific materials, including a herbarium, most of which is stored at M. G. Kholodny Institute of Botany NAS of Ukraine. As a taxonomist, he described more than 250 new taxa of vascular plants from 37 families (Brassicaceae, Asteraceae, Boraginaceae Rosaceae, Chenopodiaceae, Lamiaceae, etc.). As an expert of flora and landscape art, A. Andrzejowski took part in the creation of parks (primarily within estates in Podillia), some of which have survived (e.g., in Stavyshche, Kyiv Oblast), but most of them have been lost. A. Andrzejowski almost constantly combined his research activities with pedagogical work: he taught pupils and students of the Volynian Gymnasium (Kremenets Lyceum), St Volodymyr Imperial University of Kyiv, and the Prince Bezborodko Physical and Mathematical Lyceum of Nizhyn. He belonged to the Vilna-Kremenets Scientific School with the classical traditions of an integrated approach to the study of nature. Most of the biography and various aspects of A. Andrzejowski’s activity are discussed in numerous studies, including some of our previous publications. His preserved scientific heritage, in particular botanical works and herbarium collections, also have not escaped the attention of scientists.

Marine Isotope Stage 3

Abstract. The Marine Isotope Stage 3 (MIS 3) is considered a period of persistent and rapid climate and sea level variabilities during which eustatic sea level is observed to have varied by tens of meters. Constraints on local sea level during this time are critical for further estimates of these variabilities. We here present constraints on relative sea level in the Marmara and Black Sea regions in the northeastern Mediterranean, inferred from reconstructions of the history of the connections and disconnections (partial or total) of these seas together with the global ocean. We use a set of independent data from seismic imaging and core-analyses to infer that the Marmara and Black Seas remained connected persistent freshwater lakes that outflowed to the global ocean during the majority of MIS 3. Marine water intrusion during the early MIS-3 stage may have occurred into the Marmara Sea-Lake but not the Black Sea-Lake. This suggests that the relative sea level was near the paleo-elevation of the Bosporus sill and possibly slightly above the Dardanelles paleo-elevation, ~80 mbsl. The Eustatic sea level may have been even lower, considering the isostatic effects of the Eurasian ice sheet would have locally uplifted the topography of the northeastern Mediterrranean.

This year marks the 105th anniversary of the operation conducted during the First World War: during this operation Russian troops, after a series of successful actions on land and at sea, captured the Black Sea port of Trebizond (today Trabzon). The capture of Trebizond helped to improve the basic conditions of the Black Sea Fleet and enabled an unimpeded delivery of reinforcements by sea to the right flank of the Russian army in the Caucasus. As a result, the Russian empire was close to establishing control over a significant part of the Ottoman Turkey’s territory. In the aftermath of the operation, the local Muslim population left Trebizond together with the Turkish army. The Russians, who entered the city without a fight, set for the transforming the city in their own way. Turkish historians, using the material of the Ottoman, Russian, and foreign periodicals, as well as archival documents, have studied in detail the intricacies of the Russians stay in the city, revealing also the damage caused by the war to the cultural and historical heritage of the region. This article provides a brief analysis of selected Turkish studies dedicated to the 100th and 105th anniversary of the Trebizond operation. It also discusses the issue of war refugees and the activities of Russian scientists, who were engaged in the collection of historical monuments in Trebizond during the war.
