Настоящая статья является второй из цикла статей, посвященных корректировке кодекса ИМО по остойчивости в части ограничений продольной качки. В ней рассмотрены подходы к ограничениям по погоде из условий, возникающих при продольной качке для судов различных типов и предложены критерии оценки этих явлений на нерегулярном волнении разной интенсивности. На основании выполненных систематических расчетов продольной качки на нерегулярном волнении получены зависимости амплитуд вертикальной и килевой качки, а также дополнительного сопротивления от скорости и интенсивности волнения для транспортных судов. Полученные формулы позволяют оценить отдельные показатели мореходности. При этом ставится цель расширения нормативной базы для обоснованного назначения эксплуатационных ограничений по погоде и району плавания судов при совершенствовании Правил Российского Морского Регист­ра Судоходства на основе общего подхода к нормированию мореходности, со­гласующегося с методикой разработки новой Международной конвенции о гру­зовой марке 2000. Предлагаемый подход к определению дополнительных критериев мореходности для оценки эксплуатационных ограничений судов по погоде из условий мореходности может быть использован на практике для совершенст­вования нормативных требований Регистра. This article is the first in a series of articles on the revision of the IMO code on stability in terms of longitudinal pitching restrictions. It describes the approaches to the restrictions on the weather conditions that occurs when the longitudinal pitching is accompanied by flooding of the deck and slaming for ships of various types and the criteria of assessment of these phenomena on an irregular waves of varying intensity At the same time, the goal is to expand the normative base for the reasonable designation of operational restrictions on weather and ship navigation area while improving the Rules of the Russian Maritime Register of Shipping on the basis of a general approach to the rationing of seaworthiness consistent with the methodology for developing the new International Convention on Load Line 2000. The proposed approach to the definition of an additional General criterion of seaworthiness to assess the operational limitations of ships on weather conditions of seaworthiness can be used in practice to improve the regulatory requirements of the Register.

This article is the fifth in a series of articles devoted to the adjustment of the IMO stability code in terms of pitching limitations. It considers approaches to weather restrictions based on the conditions arising during pitching for ships of various types and proposes criteria for assessing these phenomena on irregular waves of different intensities. On the basis of the performed systematic calculations of pitching on irregular waves, the dependences of vertical accelerations along the length of the vessel on the speed and intensity of waves for transport vessels were obtained. The formulas obtained make it possible to estimate the specified indicator of seaworthiness. At the same time, the goal is to expand the regulatory framework for the justified assignment of operational restrictions on the weather and the area of navigation of ships while improving the Rules of the Russian Maritime Register of Shipping on the basis of a general approach to the regulation of seaworthiness, consistent with the methodology for the development of a new International Convention on Load Mark 2000 . The proposed approach to the definition of additional seaworthiness criteria for assessing the operational limitations of ships by weather based on seaworthiness conditions can be used in practice to improve the regulatory requirements of the Register.

Evasive action in ship-ship encounter has to be carried out on time and in line with the international convention on collision regulation – COLREG. The convention not only includes a set of rules defining types of relations between encountering ships but also indicates appropriate action to be taken in a given encounter. One of such encounters is crossing, where, in case of a collision situation, a give-way ship has to take an appropriate action in due time. However, a stand-on vessel is also given an opportunity to manoeuver, if it is made clear to her that the other ship is not fulfilling her obligations. However, it is difficult to specify, at which point in time in the course of an encounter, the stand-on ship has to take an action in order to avoid collision. It is understandable, as this parameter depends on numerous factors, both endogenous (e.g. ship characteristics, her maneuverability), and exogenous (e.g. type of encounter, weather conditions). Therefore in this paper we make an attempt towards the definition of the critical area for a maneuver of a stand-on ship, in the situation where the give-way vessel does not take an action. This is determined with the use of a hydrodynamic model of ship motion, and series of simulations conducted for several types of encountering ships under various conditions. Once determined, the critical area demarcates the no-go area around the own ship, where any other ships on collision courses must not enter. Otherwise a collision cannot be avoided by an action of one ship alone.

The work is devoted to the solution of the issue of economic and safe transportation of goods and passengers by road. This transportation depends on the condition of roads, road surface, vehicle type and weather conditions. Weather conditions are taken into account both in terms of visibility (meteorological) and in terms of the coefficient of adhesion. The general criterion for assessing all conditions is the average speed of the vehicle, taking into account weather and road conditions. Weather conditions are determined by the type of visibillity: clear weather, rain, snowfall, blizzards, rain. By the coefficient of adhesion: dry surface, normal, wet, snow, ice. By road conditions: category of road, width of the travel section, radii of horizontal curves, longitudinal slopes, width of the road, the state of surface (coefficient of solidity). According to weather conditions, the calendar year is divided into three periods according to the conditions of cars’ movement. The first (winter) - December, January, February, March; second (spring-summer) - April, May, July, June, August; third (autumn) - September, October, November. The use of weather conditions in the Northern regions of Ukraine is presented in this work.

Navigation Safety

By adjusting the maintenance approach towards the significant components of ship’s engines and equipment, through the use of operational data from the ship machinery’s daily reports, higher operability and navigation safety can be achieved. The proposed maintenance adjustment model consists of an operation data analysis and risk analysis. The risk analysis comprises the definition of the upper and the lower risk criterion, as well as the definition of a risk index. If the risk index is higher than the lower risk criterion, the component is significant, while it is not significant and has an acceptable risk index if the risk index is lower than the lower risk criterion. For each significant component with a risk index found to be “unacceptable” or “undesirable”, an efficient maintenance policy needs to be adopted. The assessment of the proposed model is based on data regarding the power engine original operation throughout a 13-year period. The results of engine failure examinations reveal that the exhaust valve is the most vulnerable component with the highest rate of failure. For this reason the proposed model of adjusting the maintenance approach has been tested on the exhaust valve sample. It is suggested that the efforts to achieve higher ship operability and navigation safety should go in the direction of periodical adjustments of the maintenance approach i.e. choosing an efficient maintenance policy by reducing the risk indices of the significant engine components. KEY WORDS: maintenance adjustment approach, risk analysis, risk index, lower risk criterion, upper risk criterion, significant components, ship navigation

Emigration has been known to mankind for more than a century. We name the factors contributing to emigration, give examples from the history of emigration both abroad and Russia. We emphasize that at the present time, Russian citizens emigrate to other countries, using the right to freely leave the state, and can also have dual citizenship under Russian law, or renounce citizenship, and then get it again. We pay special attention to the settlement of the territory of North Caucasus, which began in the 8th – 7th – 6th – 5th thousand BC. We analyze the features of emigration of people from North Caucasus after the October Revolution of 1917. The specifics of the emigration of people from this region of country are emphasized. Thus, the majority of people emigrated to the Ottoman Empire, and then moved to Europe. We indicate that in fact, after the adoption of the Decrees of the Central Executive Committee, the SNK of RSFSR in 1921, “On the deprivation of the rights of citizenship of certain categories of persons who are abroad” many emigrants from Russia, including North Caucasians, have become disenfranchised. This circumstance greatly influenced the publication of the Nansen passport (it was introduced in 1922 and became widespread in 1924), according to which emigrants were granted a number of legal and social rights. In addition, it is applicable to emigrants from Russia, including from the North Caucasus, in 1922 and 1926. The Geneva definition of “Russian refugee” was given, and the International Convention on the International Status of Refugees of 1933 created an alternative to naturalization for refugees from Russia. Subsequently, before the outbreak of the Second World War, people received, as a rule, the citizenship of the countries in which they began to live.

Health And Well Being

The debate over climate change, both from natural causes and human activity, is not new. Although the Baron C.-L. de Montesquieu is undoubtedly the best known Enlightenment thinker on the topic of climatic determinism, others, notably the Abbé Du Bos, David Hume, and Thomas Jefferson, observed that climatic changes exerted a direct influence on individuals and society and that human agency was directly involved in changing the climate. Climate—from the Greek term klima, meaning slope or inclination—was originally thought to depend only on the height of the Sun above the horizon, a function of the latitude. A second tradition, traceable to Aristotle, linked the quality of the air (and thus the climate) to the vapors and exhalations of a country. The Hippocratic tradition further linked climate to health and national character. As late as 1779, the Encyclopdédie of Denis Diderot and Jean le Rond D’Alembert defined “climat” geographically, as a “portion or zone of the surface of the Earth, enclosed within two circles parallel to the equator,” in which the longest day of the year differs in length on its northern and southern boundaries by some quantity of time, for example one-half hour. The article goes on to mention Montesquieu’s position on “l’influence du climat sur les mœurs, le charactère, et les loix des peuples.” The second definition of climate provided by the Encyclopdédie was medical, identified primarily as the temperature of a region and explicated through its effects on the health and well-being of the inhabitants. The idea that climate influenced culture was derived in part from the writings of ancient and medieval philosophers, geographers, and historians, including the works of Hippocrates, Albertus Magnus, and Jean Bodin. With no established science of climatology, Enlightenment thinkers apprehended climate and its changes primarily in a literary way. They compared the ancient writings to recent weather conditions, linked the rise and fall of creative historical eras to changes in climate, and promoted a brand of climatic determinism based on geographic location and the quality of the air.

The chapter is a presentation of the newest international human rights treaty, which entered into force in 2010. It is a very innovative and modern instrument, with a precise definition of the victim of a crime of enforced disappearance, as an autonomous crime, and a broad codification of the ‘right to truth, to justice and to reparation’ enshrined in article 24 of the treaty. As the ILC is working on the draft of an international convention for the prevention of crimes against humanity, it is important to avoid watering down the key legal progress enshrined in the International Convention for the Protection of All Persons from Enforced Disappearance.

SummaryThe proliferation of private military and security companies has attracted significant public and scholarly attention during the last decade. This comment examines the United Nations Draft International Convention on the Regulation, Oversight and Monitoring of Private Military and Security Companies (Draft Convention). It discusses the significance of the Draft Convention and then describes the approach taken to the regulation of this controversial topic. Several problematic elements of the Draft Convention are identified including the definition of prohibited activities, State responsibility for the conduct of private military and security companies and the proposed International Criminal Court referral mechanism. Finally, specific policy recommendations are made for the government of Canada as a home state and contracting state of private military and security services, irrespective of the progress of negotiations on the Draft Convention.
