In this paper, the authors present some research results of wearing process and rock destruction by diamond grit of core bit depending on drilling regime, rock hardness, diamond grit strength, etc. through the simulation of the interaction effect between diamond grit attached to the core bit and the rock. The relationship of the wear rate and rate of penetration of diamond core bit to the rotation per minute has been tested. On the basis of the research results, the authors have proposed solutions to select the appropriate technology for diamond drilling to improve the efficiency of solid mineral exploration in Vietnam.

В статье исследуются события бескоролевья 1733 г. в Речи Посполитой. Согласно «трактату Левенвольде» компромиссным кандидатом на избрание монархом Речи Посполитой был португальский инфант дон Мануэль, которого предложила Австрия. Россия больше склонялась к кандидатуре «пяста». Россия оказалась не подготовленной к началу бескоролевья. Бывшие российские союзники магнаты ВКЛ рассорились с российским послом Фридрихом Казимиром Левенвольде и перешли на сторону Франции. В конце февраля 1733 г. в ВКЛ направили Юрия Ливена, который от имени российской царицы предложил поддержку в получении короны Михаилу Вишневецкому и Павлу Сангушке. Принятое на конвокационном сейме решение об избрании королем «пяста» и католика показало популярность Станислава Лещинского. В результате вслед за Австрией Россия поддержала кандидатом на корону Фридриха Августа. Магнаты ВКЛ до последнего оставались конкурентами о короне. Оппозиция Лещинскому объединилась под лозунгом защиты «вольного выбора» и поэтому в ней остались кандидаты «пясты», которые не могли уступить друг другу, и согласились на компромисс – кандидатуру Фридриха Августа. Для противодействия возможному избранию Лещинского Россия создала в ВКЛ новоградскую конфедерацию. Ее организатором стал новоградский воевода Николай Фаустин Радзивилл. Эта конфедерация становится основой Генеральной Варшавской конфедерации, которая 5 октября 1733 г. избирает королем саксонского курфюрста. The article examines the events of the «kingless» year of 1733 in the Polish-Lithuanian Commonwealth. According to the Levenwolde Treaties the compromise candidate for the Commonwealth’s throne was the Portuguese Infante Don Manuel, who’s candidacy was proposed by Austria. Russia, in turn, leaned towards the «pyasta» candidate. The Russian Empire was clearly unprepared for the start of the kingless period. Russia’s former allies – magnates of the Grand Duchy of Lithuania – came into conflict with the Russian ambassador Frederick Kazimir Levenwolde and sided with France. In late February of 1733, Empress Anna Ioanovna of Russia sent Yuri Liven to the Grand Duchy of Lithuania, who offered official support in the struggle for the crown to Mikhail Vishnevetsky and Pavel Sangushka. The electoral decision made at the Sejm proved the popularity of the «pyast» and Catholic candidates, specifically – Stanislaus Leschinsky. In turn, Russia – following Austria – showed its support for the candidacy of Frederick August. The magnates of the Grand Duchy of Lithuania remained in opposition in the crown issue until the very last. Opposition to Leschinsky was united under the motto of «free choice». For that reason, it was comprised of «pyasta» candidates, who were in a deadlock with one another, and were now ready for the compromise candidacy of Frederick Augustus. In order to counter the possible election of Leschinsky, Russia created the Novograd Confederation in the Grand Duchy of Lithuania. It was organized by the Novograd Voevoda Faustin Radzivill. This confederation became the core of the General Warsaw Confederation that – on October 5th 1733 – elected the Saxon King to the throne of the Polish-Lithuanian Commonwealth.

Radical Left

The emergence of inclusive populist parties disputes the social construction of the ‘people’ to the exclusive populism, recently generating new academic debates. Do the new radical left parties have a nationalist character? Are populism and nationalism two inseparable dimensions? Drawing on an original dataset in Spain, this article shows that Podemos’ supporters are significantly less nationalist, expressing more open attitudes towards cultural diversity and immigration, and lower levels of Spanishness than voters from other parties. Arguably, Podemos operates as an antagonistic political option to the traditional positions of the populist radical right (PRR), building an inclusive imagined community around a type of constitutional patriotism or republican populism. These findings contribute to the scholar debate on the relationship of nationalism and populism, bringing to discussion the core values of the supporters of a populist party as a complementary element to its categorization.

This paper proposes a novel multi-radius density clustering algorithm based on outlier factor. The algorithm first calculates the density-similar-neighbor-based outlier factor (DSNOF) for each point in the dataset according to the relationship of the density of the point and its neighbors, and then treats the point whose DSNOF is smaller than 1 as a core point. Second, the core points are used for clustering by the similar process of the density based spatial clustering application with noise (DBSCAN) to get some sub-clusters. Third, the proposed algorithm merges the obtained sub-clusters into some clusters. Finally, the points whose DSNOF are larger than 1 are assigned into these clusters. Experiments are performed on some real datasets of the UCI Machine Learning Repository and the experiments results verify that the effectiveness of the proposed model is higher than the DBSCAN algorithm and k-means algorithm and would not be affected by the parameter greatly.

Abstract How should we think about the winners and losers from globalization? What role can narrative analysis play in doing so? We argue that to be useful, identifying politically relevant narratives on the distributional effects of globalization, and the role played by trade agreements in fostering such effects, must have an empirical basis. Characterizing different narratives and inferring from each the implications for the (re-)design of international agreements without analysis whether the suggested policy reforms will help losers from globalization does not advance matters. Effectively employed, narrative analysis can extend our knowledge of the politics of trade and policy towards globalization more generally. To do so, it must have an analytical foundation, centre on the relationship of the narrative to the facts, ask which narrative is more persuasive based on empirical evidence and assess whether inferred policy implications will address the core issues of concern to those who employ the narrative.

Untangling the relationship of law and liberty is among the core problems of political theory. One prominent position is that there is no freedom without law. This article challenges the argument that, because law is constitutive of freedom, there is no freedom without law. I suggest that, once properly understood, the argument that law is constitutive of freedom does not uniquely apply to law. It also applies to social norms. What law does for freedom, social norms can do too. Thus, I claim the question facing us is not the easy one of either law or social norms. Respecting this draws attention to the unique risks to our freedom introduced by both sets of norms.

This research discusses the protection and management of biodiversity in environmental law perspective. Indonesia has a large biodiversity which needs to be managed and protected. Indonesia has enacted laws and regulations on biodiversity, but they are still weakly and less effectively implemented. Furthermore, it is a fact that regulations stipulated by the government or certain sectors do not still accommodate interests of all parties. Legal issues examined here is whether Act No. 32 of 2009 on the Protection and Management of the Environment has protected biodiversity in Indonesia and how is the implementation of policies in protecting biodiversity during this time. The research results show that Act No. 32 of 2009 on the Protection and Management of the Environment has protected the biodiversity in Indonesia. Implementation of policies about the protection and management of biodiversity during this time can be viewed from the relationship of policy between the government and the regional government, such as the authority and institutions to manage and protect the environment, including instruments to manage biodiversity.

The Relationship

Fifty-nine samples from a 560cm gravity core of late Quaternary age (PS1003-2), collected at a depth of 2796m in the Weddell Sea, were examined for Ostracoda. The fauna was sparse but, from a total of 556 valves, the rather low diversity fauna of 19 species belonging to 11 genera and 3 families was identified. The study is principally concerned with species diversity, originations and extinctions, inter-relationships between species and the relationship of the fauna to different water masses. With respect to species diversity and origination/extinction patterns, two distinct phases are apparent: an initial diversification (originations only), followed by a phase of overall stable diversity (originations approximately matched by extinctions). The ostracod fauna is closely comparable to that described by authors as typical of North Atlantic Deep Water but is actually from the Antarctic Bottom Water (AABW). Two of the principal constituent species Henryhowella dasyderma (Brady) and H. asperrima (Ruess) seem to be mutually exclusive within the core. Changes in the fauna through the core seem to be related to climatic cycles.

The relationship and interaction between quantitative (number and dimensions of trees) and value indicators in Austrian pine plantations were researched in Forest Management Unit ?Suboticke Sume? (Forest Estate ?Sombor? - FA ?Subotica?). As the measurement of quantitative elements is more simple, their effect on wood value can be used as a rather reliable support in the value estimation of standing trees. The analysis of the research results shows that there is a strong inter-relationship of the study elements, so they can be a good foundation for the estimation of standing timber value in artificial Austrian pine plantations at the given site.
