Zmiany strukturalne przemysłu Polski w warunkach kryzysu gospodarczego
The global economic crisis which started in 2007 in the United States of America, at different times and to a different extent affected various sectors and national economies of the world. In Poland, its symptoms were noticeable later than in other countries. In the first phase of the crisis (2007- 2008), there was no direct effect, due to the fact that initially the turmoil on global financial markets had weaker effect on the national economy, and it was limited mainly to capital markets, affecting the sectors of agriculture, industry, and services to a lesser extent. However, as recession grew in force, the crisis gradually began to affect also the results of economic activity, including industry. In 2009, a significant decrease in the value of production sold, as compared to the previous year, was observed. The question is whether this had been reflected in changes of spatial industrial structure. The five-year period of the economic recession seems to be long enough to assess such changes. Therefore, the paper analyses the transformation of the spatial structure of Polish industry during crisis, based on the basic indicators of potential, such as employment and the value of production sold, as well as concentration coefficients. The year 2007 was adopted as the base year, treating it as a pre-crisis year. The conclusions of the detailed analysis indicated that the impact of crisis on the change of the spatial structure of the Polish industry is very limited and the observed trends of change did not differ substantially from the general industrial development trends in Poland, identified by previous studies. It should be noted, however, that the structure of industry is characterized by high “inertia” due to the complexity and size of the investment process. Therefore, in the following several years no deep and sudden transformation should be expected, even during economic recession.
Contemporary Trends in the Development of the Pharmaceutical Industry in the World
The pharmaceutical industry remains today a prominent high-technology sector of the economy,and consistently maintains its competitiveness on the world market at a very high level. Similarly to aircraft and spacecraft manufacturing and the electro-energy industry, pharmaceutical industry belongs to a group of innovative high-technology industries, which are based on scientific research results processed for industrial activities. The purpose of this study is to present and analyse global trends currently observed in the pharmaceutical industry in the world. In an era of increasing globalization, new prime movers of the development of the pharmaceutical industry are the countries from peripheralregions, mainly members of the BRICS group. For this reason, this article focuses on the emerging Asian and Latin American markets, next to the United States and countries of Western Europe. At the beginning of the twenty-first century, Brazil and China deemed the stimulation of the pharmaceutical industry one of the prime determinants of their future economic development. The following paper at first presents characteristics of the pharmaceutical industry products: innovative and generic medicines, medications available without prescription, biological agents, biosimilars and pharmaceutical substrates. Furthermore, the author specifies the properties and rates the dynamics of changes that are taking place in the global pharmaceutical market, while explaining the specifics of the relocation of the pharmaceutical industry. By comparing the number of publications in the field of pharmacy in selected countries of the world, the author confirmed the increasing importance of this industry on the global economy. In the last part of the article, the author presents the structure, number and distribution of clinical trials on a global scale. To illustrate the trends currently taking place in the development of the pharmaceutical industry, the author used raw statistical data in the field of pharmacology and literature on the subject.
The crystal structure of stilpnomelane. Part II. The full cell
Summary The structural formula of stilpnomelane averaged from 37 representative literature analyses and based on the determined structure is (Ca,Na,K)4(Ti0·1Al2·3Fe35·5Mn0·8Mg9·3)[Si63Al9](O,OH)216·nH2O. Ferrostilpnomelanes have up to 12 R 3+ cations in the octahedral sheet, ferristilpnomelanes commonly have between 24 and 30 R 3+ cations, rarely up to 37. The two groups can be distinguished by accurate X-ray powder diffraction, ferrostilpnomelanes having d 001 less and a greater than have ferristilpnomelanes. The unit cell is triclinic, a = b∼21·8 Å, γ = 120°, d 001∼12·2 Å, P . Hexagonal groups or ‘islands’ of 24 silicon-oxygen tetrahedra co-ordinate to the octahedral sheet, the centres of the ‘islands’ are displaced by 5a/12, 8b/12 on either side of the octahedral sheet as a result of warping of this sheet to permit articulation with the smaller tetrahedral sheet. The 24-tetrahedra ‘islands’ are linked laterally by 6-member rings of inverted tetrahedra, which in turn link at their apices to like rings connecting the next sheet of ‘islands’. Thus a single tetrahedral layer is 4 tetrahedra thick and has symmetry 6/m. The 6-member rings of tetrahedra act as hinges permitting up to 0·5 Å extension or contraction of the tetrahedral sheet to accommodate variations in the octahedral sheet dimensions with varying R 2+/R 3+ ratio.
