unconventional deposits
Opis:
In Poland, the focus so far has been on unconventional gas deposits, but equally interesting are unconventional oil deposits. As a result of intensive research in the past few years, it was found that we have significant deposits of oil shale, which may be rich in both gas and oil. Undoubtedly, after a period of research and analysis on the prospects of the presence of shale gas in these structural units would come the turn of the shale oil. In the article on the basis of industrial materials have been characterized: — shale formations in the basin of the Baltic - Podlasie - Lublin (potential of the Silurian and Ordovician), — Prągowiec ravine (southeast of Kielce) - Graptolitic Shales (Silurian) — menilite shales in the Carpathians external-especially of south of Rzeszów in municipalities Błażowa, Boguchwała, Wojaszówka. — discovered heavy oil deposit Lubaczów

The paper examines some linguistic aspects of Jerzy Andrzejewski's novel "Wielki Tydzień", and compares them with the French version of the text. It focuses on the figure of hypallage, used recurrently by Andrzejewski. Usually defined as a transferred epithet, hypallage can also be conceived of as a partly fixed expression whose elements have regainded – in a specific context – their combinatorial freedom. The paper describes the different functions of this type of transfer in the Polish original. It also examines the attitude adopted by the French translator regarding these unusual co-occurrences.

Opis:
It is known, that small disturbances generated by the micro actuators can alter large-scale vortex structures, and consequently, generate appreciable aerodynamic moments along all three axes for flight control. In the current study, we explored the possibility of independently controlling these moments. We perform analytical simulations showing optimal position of LEX generators, and water tunnel measurements showing effectiveness of MEX generators as MAV control devices. We applied array of actuators located on either the forward or the rear half section of the leading edge. Both one- and two-sided control configurations have also been investigated. Experimental results showed that asymmetric vortex pairs were formed, which leads to the generation of significant torques in all three axes. The article presents typical vortical flow over a delta wing, water tunnel at Wroclaw University of Technology, experimental setup and procedures, static test results on water tunnel testing including normal forces, pitching and yawing moments, maximum values of rolling, pitching, and yawing moment coefficients, effectiveness of pitching and yawing control.

Opis:
Research background: Transfer of newly created money through unconventional monetary measures follows the official European Central Bank distribution key. Yet, it does not take into account the ability of individual countries to drive growth process in other economies. Money spent to boost domestic credit provisioning in growth pole-like economies is more likely to spill over to other adjoined economies and help them to recover, even in the presence of depressed domestic demand and/or overleveraged domestic banking sector. Purpose of the article: This paper reports growth pole scores for 19 euro area countries, and compares it to the official distribution key used to transmit newly created source of funding. Methods: We modify the procedure developed in World Bank (2011) for growth pole com-putation in order to account for strength of linkages connecting member states. Findings & Value added: Our results suggest that the official distribution key might not be completely optimal once looking at the growth pole scores. Countries small in economic size (Baltic states, Slovakia and Slovenia) would benefit from a more differentiated distribution, as they strongly outperform their benchmark set by the official distribution key. On the other hand, big euro area economies do not achieve the levels used in official distribution key, taking into account their growth pole potential for other euro area economies.

Unconventional division by zero can apply to those cases in which some directly incomparable (i.e. unlike or represented in different algebraic bases) abstract objects taken from two distinct algebraic spaces are acted upon or need to be compared. Multispatial reality paradigm is thus necessary for overcoming conceptual inconsistencies arising in the domain of complex numbers when certain valid abstract reasonings from the hypercomplex domains of quaternions and octonions are carried over back to the 2D complex domain.

Opis:
This paper applies a DSGE model to find whether the way of financing QE2 matters for the reaction of the economy. The model includes a segmented bond market structure, thus the large-scale asset purchases may successfully influence the economy. It is shown that the effects on macroeconomic variables are very similar regardless of whether the government finances the purchases by lump-sum taxes or by short-term debt which signifies that the quantitative deviation from Ricardian equivalence introduced by bond market segmentation is insignificant. The redistribution effects caused by financing are noticeable.

Opis:
The article presents the watercraft recognition and identification system as an extension for the presently used visual water area monitoring systems, such as VTS (Vessel Traffic Service) or RIS (River Information Service). The watercraft identification systems (AIS - Automatic Identification Systems) which are presently used in both sea and inland navigation require purchase and installation of relatively expensive transceivers on ships, the presence of which is not formally required as equipment of unconventional watercrafts, such as yachts, motor boats, and other pleasure crafts. These watercrafts may pose navigation or even terrorist threat, can be the object of interest of the customs, or simply cause traffic problems on restricted water areas. The article proposes extending the traffic supervision system by a module which will identify unconventional crafts based on video monitoring. Recognition and identification will be possible through the use of image identification and processing methods based on artificial intelligence algorithms, among other tools. The system will be implemented as independent service making use of the potential of SOA (Service Oriented Architecture) and XML/SOAP (Extensible Markup Language/Simple Object Access Protocol) technology.

The correlations and the influence of the monetary policy pursued by the central banks of developed countries, primarily by the Federal Reserve System (the central bank of the United States), on the economies of developing countries is a subject of research, especially since the outbreak of the last financial crisis. Decisions concerning shifts in attitudes in the monetary policy taken by the monetary authorities of the largest economies, influence investors’ behaviour. Due to globalization and financialization, short-term capital flows occur very quickly and on a significant scale. Argentina is an illustration of the consequences of monetary policy tapering by the FRS for the economy of a developing country. Argentina was supported during the period of disturbances by the International Monetary Fund. Nevertheless, it seems that this solution is insufficient in view of the globalization of the effects of the monetary policy pursued by the economically strongest countries.

Opis:
Local government units resort to external repayable sources of financing their own activity, mainly those connected with investments, when the financial sources they have at their disposal are insufficient. However, owing to an unfavorable financial situation, some of them lose their creditworthiness because their debts exceed the legal limit. In such a situation, they decide to use the so-called unconventional instruments, which, although they provide certain long-term benefits, in a longer time perspective lead to negative consequences, connected mainly with diminished financial liquidity and the necessity to bear inflated costs of debt service. The aim of the paper is to present the reasons for using unconventional instruments of financing budget needs by decision-makers, as well as their specific character and economic effects, particularly as regards the financial stability and security of LGUs, the transparency of local finances and the related hazards. The achievement of this aim required analysis of the literature devoted to the subject, reports of controlling institutions and statistical data regarding the debt level of LGUs.

Opis:
This paper studies the effect of central banks’ targeted refinancing operations on bank lending. It utilizes data from the European Central Bank’s targeted longer-term refinancing operations (TLTROs) together with monthly bank level balance sheet data from multiple countries. The effect of targeted policy is identified utilizing the institutional setting that provides natural instrumental variables and a proxy for credit demand. Unlike previous papers, this paper studies the effects on corporate loans and loans for consumption separately. The cumulative effect of TLTROs on participating banks’ stock of corporate loans is estimated to be significant (about 20 per cent). However, the effect on lending for consumption is found close to zero. Furthermore, the positive effects on corporate loans are found to be driven by crisis countries suggesting that the effectiveness of monetary policy depends on the economic conditions. The paper also finds some evidence that the effect on government bond purchases is negative. This result is very different from the earlier results regarding non-targeted liquidity operations.

The world is undergoing a radical transition to a low-carbon economy and natural gas is considered an important bridge in the transition of energy in the world. The potential for natural gas, especially unconventional gas, is very large, which will significantly affect the future energy structure in all regions of the world. However, the conditions for developing these resources are different between regions and countries. The development of unconventional gas is now facing many challenges, even opposition because the problem of extracting unconventional gas is very complex and the total impact is unknown. Therefore, at present, the expansion of unconventional gas remains a question for countries that possess and desire to exploit these resources. This article will analyze the opportunity and challenges of unconventional gas relying on the development of shale gas in recently.

Research background: In this research paper, an attempt is made to evaluate the impacts of ECB's unconventional monetary policy which has been applied after Global Financial Crisis. Because of the new economic and monetary conditions, the effectiveness of conventional monetary tools has been questioned. Purpose of the article: Designed models examine the consequences of unconventional monetary policy for macroeconomic variables, monetary variables and interest rates in the euro area. Particular attention is paid to the response of the price level, represented by HICP, to various monetary policy innovations. Except a shock in credit multiplier and asset purchase programme (APP), also the effectiveness of a conventional monetary tool, such as main refinancing operation (MRO) interest rate, is inspected. Methods: Use has been made of impulse responses from structural VAR models to analyze a large sample that covers the time horizon of 1999 to 2016. Several econometric tests are performed to provide a profound analysis. The conclusions from baseline models are verified in multiple robustness check models, which are specified under alternative conditions. Findings & Value added: It has been found that, in the aftermath of the Global Financial Crisis, conventional monetary instruments are effective in the short-run. In the long-run, unconventional monetary policy has a greater potential to stabilize the economy than the traditional interest rate transmission channel. The conclusions from the baseline models are verified in multiple robustness check models, which are specified under alternative conditions.

In the article, the data presented in the literature connected with Raman spectroscopy and the oil and gas industry is analyzed. This paper considered measurements of a natural gas composition in simulated in-situ conditions performed using Raman spectroscopy. The current research project is trying to develop a mobile apparatus which would use Raman spectroscopy for defining reservoir fluid compounds in high pressure and high temperature conditions. The preliminary measurements were carried out in the simulated in-situ in variant pressure conditions.

Energy security was previously considered unimportant. It started functioning only since the 70s of the twentieth century, during the oil crises. Today, the problem of energy security is increasingly being moved to an international level. The only way to do this seems to be the usage of renewable energy sources, which are present in every country whether in the form of solar, hydro, tidal, biomass, geothermal or wind energy. As the depletion of mineral resources, should increase the share of renewable sources, so that for several years it was possible to acquire energy without appreciable problems for customers.

Opis:
Unconventional reservoirs play an enormous role in hydrocarbon production in the United States. Marcellus Shale, a Devonian black shale found in the Appalachian Basin, has shown notable promise in the past few years. Shale is a complicated, naturally fractured reservoir with ultra-low matrix permeability. The gas is stored in the limited pore space of these rocks and a sizeable fraction of the gas in place may be adsorbed on the organic material. Shale gas reservoirs differ from conventional reservoirs in that massive stimulation treatments are requiredto achieve economic production. Horizontal wells are the most effective in providing access to the formation to perform multi-stage hydraulic fracturing treatments. The limited field experience with multiple hydraulic fractures in horizontal wells completed in Marcellus Shale indicates that significant increase in initial production can be achieved as the number of hydraulic fractures is increased. However, the production performance, particularly over longer time periods, is not well established. The objective of this study was to investigate the long term production performance of multiply fractured horizontal wells completed in Marcellus Shale. Historical production data and stimulation treatment information have been collected and analyzed for a number of horizontal wells both in West Virginia and Pennsylvania. A commercial reservoir simulator which accounts both for dual porosity behavior and the adsorbed gas was utilized to history match the production performance. Based on the results of the history matching, the long term production performances of the multiply fractured horizontal wells were predicted. The results were then utilized to investigate the production decline behavior of Marcellus Shale horizontal wells. A number of conventional as well as shale specific production decline models were considered in these investigations. The results indicated the presence of different flow periods. The hydraulic fractures appear to dominate the early production performance which is characterized by linear flow. Gas desorption appears to impact on production decline behavior during the intermediate period. The late production is influenced by the reservoir boundaries and is controlled by natural fracture properties. A single decline model often cannot predict the entire production behavior and conventional decline analysis based on the early production data can lead to significant over-prediction of the future production rates or reserves. The results of this study can be utilized as guideline to investigate the feasibility horizontal wells with multiple hydraulic fractures and optimize the production from the shale formation.

Opis:
This paper presents literature on theoretical and practical aspects of gas production from shale using carbon dioxide fracturing. Development of technical and environmental aspects of carbon dioxide fracturing technologies is also considered. Patents applicable to carbon dioxide fracturing are reviewed. In this work experiments were also conducted to verify possibility of carbon dioxide sequestration in the shale gas reservoirs. Carbon dioxide and methane (CH4) storage capacity was measured as Langmuir volumes. The adsorption capacities depend on content of organic matter in the shale rocks and pressure. The obtained results indicate that developing of carbon dioxide fracturing is reasonable.

Opis:
The world is developing at a very high rate, in fact all areas of life such as science, technology, medicine and cyberspace. At the same time, proportionally to this progress and in relation to the development of technology, security-related concepts have evolved and are becoming a priority for many countries. The new face has come also for military activities. Developed countries have dealt with problems such as providing food and water to citizens, controlling the epidemic, and guaranteeing education, however, regardless of the level of urbanization, they face a new threat – a hybrid war. What are its features? What is its nature and direction? How to recognize its beginning and end? What measures are used to carry it out? Are international organizations able to counteract it effectively? This article attempts to answer the above questions and diagnoses the current level of threat of a hybrid war for Poland, mainly in the context of a specific geopolitical situation.

Opis:
Linseed, commonly known as flaxseed, is a fibre-rich food product. According to the recent study prepared by the American Institute for Cancer Research (AICR), an adequate intake of dietary fiber contributes to reducing the risk of colorectal cancer. In addition, the flaxseed and the oil extracted from it are considered to be food products with a high content of anti-inflammatory, unsaturated α-linolenic acid (ALA). However, the authors of the most recent scientific research have assigned the anticancer significance of flax seeds to plant lignan - secoisolariciresinol diglycoside (SDG), of which flaxseed is the main food source. This article provides a review of the world scientific literature together with an assessment of the validity of dietary supplementation with SDG from flaxseeds in cancer and during chemotherapeutic treatment. The paper also presents the European Food Safety Authority (EFSA) and the US Food and Drug Administration (FDA) view on dietary supplementation with flax seeds and its lignans. Additionally, selected dietary supplements available on the Polish market containing SDGs, linseed oil or linseed were analysed, together with a description of their intended use suggested by the manufacturers.
