A broadband radio study of the average profile and giant pulses from PSR B1821-24A

We present the results of wide-band (720-2400 MHz) study of PSR B1821-24A (J1824-2452A, M28A), an energetic millisecond pulsar visible in radio, X-rays and gamma-rays. In radio, the pulsar has a complex average profile which spans >85% of the spin period and exhibits strong evolution with observing frequency. For the first time we measure phase-resolved polarization properties and spectral indices of radio emission throughout almost all of the on-pulse window. We combine this knowledge with the high-energy information to compare M28A to other known gamma-ray millisecond pulsars and to speculate that M28A's radio emission originates in multiple regions within its magnetosphere (i.e. both in the slot or outer gaps near the light cylinder and at lower altitudes above the polar cap). M28A is one of the handful of pulsars which are known to emit Giant Pulses (GPs) -- short, bright radio pulses of unknown nature. We report a drop in the linear polarization of the average profile in both windows of GP generation and also a `W'-shaped absorption feature (resembling a double notch), partly overlapping with one of the GP windows. The GPs themselves have broadband spectra consisting of multiple patches with fractional spectral width ($\Delta\nu/\nu$) of about 0.07. Although our time resolution was not sufficient to resolve the GP structure on the microsecond scale, we argue that GPs from this pulsar most closely resemble the GPs from the main pulse of the Crab pulsar, which consist of a series of narrowband nanoshots.Comment: 16 pages, 8 figures, accepted to Ap

“DEUTSCHE WELLE” AS A MASS MEDIA LANGUAGE FOR SPECIALIST PURPOSES: PRAGMATICS, ANALYSIS, AND TRANSLATION

Purpose: Within the framework of the translation studies, the results of research on mass media texts were presented only by individual examples in the professional literature. While, for example, literary texts have developed a variety of guidelines, strategies, and models of translation. There were almost no studies on the TV news translation. We have found only a few references to this topic in scientific works dealing with mass media texts translation in general. There is still no comprehensive analysis of the German mass media translation in Ukrainian. Methodology: However the language for specialist purposes is a special style, which creates and presents to the viewer the news texts for television. Typically, the TV news services set their own requirements for the TV news language, but there are common rules followed by all TV news editors. The linguistic designing defines the light in which the events are presented and what opinion the recipient will form. Result: However, in recent years the demand for mass media texts translation has significantly increased. It was influenced by the distribution of audiovisual international information channels such as Euronews, BBC, France 24, DW. Deutsche Welle TV news which is currently being translated into thirty languages of the world, including Ukrainian. To some degree the translation of Deutsche Welle TV news into Ukrainian influences the level of Ukrainian integration into the European space. Due to a well-executed translation Ukrainians can learn about current political and economic events that take place in Europe and in the world, about the latest achievements in medicine, technology, ecology, sociology, etc. Applications: This research can be used for universities, teachers, and students. Novelty/Originality: In this research, the model of “Deutsche Welle” as a Mass Media Language for Specialist Purposes: Pragmatics, Analysis and Translation is presented in a comprehensive and complete manner

Review of overall parameters of giant radio pulses from the Crab pulsar and B1937+21

We present a review of observed parameters of giant radio pulses, based on the observations conducted by our group during recent years. The observations cover a broad frequency range of about 3 octaves, concentrating between 600 and 4850 MHz. Giant pulses of both the Crab pulsar and the millisecond pulsar B1937+21 were studied with the 70-m Tidbinbilla, the 100-m GBT, 64-m Kalyazin and Westerbork radio telescopes. We discuss pulse energy distribution, dependence of peak flux density from the pulse width, peculiarities of radio spectra, and polarization properties of giant radio pulses.Comment: 3 pages, 4 figures, to be published in the Proceedings of the conference "40 Years of Pulsars: Millisecond Pulsars, Magnetars, and More" held on August 12-17, 2007, McGill University, Montreal, Canad

Pulsar Science with the Green Bank 43m Telescope

The 43m telescope at the NRAO site in Green Bank, WV has recently been outfitted with a clone of the Green Bank Ultimate Pulsar Processing Instrument (GUPPI \cite{Ransom:2009}) backend, making it very useful for a number of pulsar related studies in frequency ranges 800-1600 MHz and 220-440 MHz. Some of the recent science being done with it include: monitoring of the Crab pulsar, a blind search for transient sources, pulsar searches of targets of opportunity, and an all-sky mapping project. For the Crab monitoring project, regular observations are searched for giant pulses (GPs), which are then correlated with $\gamma$-ray photons from the \emph{Fermi} spacecraft. Data from the all-sky mapping project are first run through a pipeline that does a blind transient search, looking for single pulses over a DM range of 0-500 pc~cm$^{-3}$. These projects are made possible by MIT Lincoln Labs.Comment: 2 pages, 1 figure, to appear in AIP Conference Proceedings of Pulsar Conference 2010 "Radio Pulsars: a key to unlock the secrets of the Universe", Sardinia, October 201

Marketing support of competitiveness of agricultural enterprises

The article examines the system of agricultural marketing with the aim of meeting the needs of consumers and achieving the competitiveness of agricultural producers in the context of determining the characteristics of agricultural activity. It is substantiated that the sustainable development of agricultural production contributes to the strengthening of the economic and social security of the state, the formation of a positive image of the country, the growth of the quality of life of the urban and rural population, the increase of export potential, the maintenance of ecological balance in rural areas, the rational use, protection and reproduction of natural resources. According to the results of the assessment of the state of agricultural production in Ukraine, a change in the assortment of agricultural products was revealed in the direction of increasing the amount of cultivation of more profitable types of crop and livestock products. It was found that agricultural products occupy a leading place in Ukrainian exports. Attention is focused on the peculiarities of agricultural production, compared to other branches of the economy, which determine the specifics of the organization of marketing at agricultural enterprises. It was revealed that marketing research in the agricultural sector is mainly carried out by intermediaries, as a result of which the largest part of the profit is concentrated in intermediary structures. The stages of the process of implementation of marketing activities at enterprises producing agricultural products are characterized. It is substantiated that for the successful conduct of competition and the introduction of niche products, it is advisable to conduct marketing research and analyze the competitiveness of agricultural enterprises in the course of financial and economic activity, which will contribute to timely decision-making regarding changes in the product range, sales markets, and the enterprise management system. It has been proven that the use of marketing tools to increase the competitiveness of agricultural enterprises is important because it will contribute to taking into account external factors of influence and internal reserves of increasing efficiency. Attention is drawn to the need to select effective methods of competition and create the basis for the identification of the enterprise, which is determined by its marketing concept

Depression of administrative-territorial units of Chernivtsi oblast: social-geographical assessment

Problem Statement and Purpose. The world economy has always developed and continues to develop cyclically, which affects the economic development of individual countries and their regions. As a result of cyclical economic development, regions are formed that maintain a progressive or stagnant type of economic development, and some of them, especially during periods of economic crisis, develop a regressive type. Thus, depressed regions or their separate territories appear, the study of which aims to identify in time the territorial disparities and polarizations of different types of the social formation of administrative units and to establish the level of their depression. It should be noted that most of the available scientific achievements concern the study of the territory of Ukraine at the regional level, and not at the subregional (raion) level. Therefore, our research allows us to shed more light on the depression of administrative-territorial units of Chernivtsi oblast, which differs from other regions of Ukraine by its natural-geographical, demographic, ethnic contrast, as well as cross-border and border position, which certainly has a significant impact on depression of regions and cities of regional significance.The purpose of this study is to conduct a socio-geographical assessment of the depression of administrative-territorial units of Chernivtsi oblast, which allows us to learn about the current state of the oblast and its raions in terms of depression, as well as identify possible steps to solve this problem.Data & Methods. To study the depression of administrative-territorial units of Chernivtsi oblast, the following main types were chosen: economic, social, and demographic. For each of these blocks, the main indicators of indicators were determined, according to which a socio-geographical assessment of the level of depression in administrative regions and cities of regional significance was conducted.Having established the rating places for each administrative-territorial unit according to the selected indicators, or their relative values, it was possible to establish the average place of each unit and, accordingly, the level of depression for each of the studied blocks. It was also established the common place of administrative units in the region by all indicators and thus identified different, according to the level of depression, regions.Results. With the help of rating research, the typification of administrative-territorial units of the oblast according to the level of economic, social, demographic, and integral depression was carried out. The most depressed were the agricultural raions of the oblast – Khotyn, and Sokyriany. However, it should be noted that Khotyn raion has the same types of depression in all its components, and in Sokyriany raion the worst is the demographic situation, and the best ‒ the economic one. The lowest level of depression is characteristic of Storozhynets raion, which is explained by its favorable geographical location relative to the oblast center, which contributes to economic and social development, as well as polyethnicity, which strengthens the demographic component
