Opis:
In this paper we study the relationship between foreign firm ownership and innovation activities in a wide group of West European and Central and East European countries. Based on a dataset including more than 100,000 firms covered by the 2014 edition of the Community Innovation Survey, we examine the role of home- and host country effects in firms’ decisions to introduce various forms of innovation. In addition, we identify a group of foreign-owned firms that specialize in exporting and interpret them as participants of hierarchic global value chains organized by multinational enterprises. We show that while foreign direct investment, especially from Germany, is positively associated with innovation, the opposite effect is observed in the case of hierarchic global value chains’ participants. The negative impact of within-multinationals global value chains on innovation is more pronounced in the affiliates located in the Central and East European countries

Opis:
Research background: A series of changes towards the greater openness to the influx of foreign labour force made in recent years in the Russian Federation prompts for analysis of immigration to this country as adopted solutions in the field of the migration policy affect other regions of destination (e.g. EU). Liberalisation of access of migrants to the Russian labour market is a part of a wider problem: competition (on an international scale) for an influx of foreign labour force. In this context, it is worth examining how the crisis which affected the Russian economy influenced the scale of immigration to Russia from the main sending countries, i.e. the countries of the Commonwealth of Independent States (CIS). Purpose of the article: The aim of the article is to show the impact of the crisis which affected the Russian economy in recent years on the scale of immigration from the CIS countries to Russia. The main hypothesis is as follows: the factor explaining immigration from the CIS countries to Russia is the difference in the level of income measured by GDP per capita (PPP) between the sending state and the country of destination. Such studies have not been undertaken so far and, due to the role of factors inherent in the concept of post-imperial migration, it becomes relevant to examine whether the factors shaping migration (including the differences in the level of income) recognised in the neoclassical theory of migration are important in explaining the flows in this area. Methods: In order to check the relationship between immigration and the economic crisis in Russia, the analysis of correlation and regression was used. Findings & Value added: It has been shown that despite the decline in GDP in Russia, immigration from the CIS countries to Russia is not decreasing. Therefore, it is a dependence different from the assumptions of the neoclassical economy according to which the reduction of differences in the level of income between the sending state and the country of destination reduces the scale of international migrations. As it has been shown, the scale of migration to Russia may not be explained by the difference in the level of GDP per capita in all CIS countries and, inter alia, political factors, conflicts or naturalisation processes become more important in shaping the scale of migration to Russia.

Opis:
The yeast Saccharomyces cerevisiae strain W303 synthesizes in the early logarithmic phase of growth dolichols of 14-18 isoprene residues. The analysis of the polyisoprenoids present in the stationary phase revealed an additional family which proved to be also dolichols but of 19-24 isoprene residues, constituting 39% of the total dolichols. The transfer of early logarithmic phase cells to a starvation medium lacking glucose or nitrogen resulted in the synthesis of the longer chain dolichols. The additional family of dolichols represented 13.8% and 10.3% of total dolichols in the glucose and nitrogen deficient media, respectively. The level of dolichols in yeast cells increased with the age of the cultures. Since both families of dolichols are present in stationary phase cells we postulate that the longer chain dolichols may be responsible for the physico-chemical changes in cellular membranes allowing yeast cells to adapt to nutrient deficient conditions to maintain long-term viability.

Opis:
The NATO wide area network provides secure IP services to NATO commands and agencies, and offers information exchange gateways to nations and coalition operations. The IP services support the NATO-wide deployment of core automated information systems (AIS), and the placement of specific functional area services (e.g., intelligence, logistics, C2IS for the services, etc.) at commands. To maintain and improve interoperability within NATO and with partners, NATO will transition from version four of the Internet Protocol (IPv4) to version six (IPv6). The transition to IPv6 will involve the IP network, the information exchange gateways, the core AIS, the functional area services, and the supporting CIS infrastructure. The IPv6 naming and addressing plan being developed supports the NATO command structure and interoperability with NATO partners. The critical issue in the planning process is to support the incremental introduction of IPv6 whilst maintaining network security and reliable interworking with existing IPv4 systems and limiting increases in operations and maintenance costs. To minimise costs and maximise effectiveness NATO is planning the transition in a timescale that is commensurate with commercial adoption in NATO countries, the technology refreshment points for major systems, and the availability of IPv6 security components. New NATO projects will prepare for the transition by detailing their IPv6 upgrade path and procuring dual stack (IPv4 and IPv6) equipment. NATO will develop and adopt standardised approaches for IPv6 protocols and network design.

The aim of this study is to describe the legal bases of the migration policy of Armenia and its practical implementation in 1995–2013. The author examined the international and national documents that provide the legal bases of Armenia’s migration policy, as well as the balance between departures and arrivals in the period 1995–2013, Armenian citizens’ reasons for emigrating and the occupations of emigrants. The study was based on the following research methods: content, system and quantitative analysis. The results of the analyses performed indicate that the objectives of Armenia’s migration policy were not completely fulfilled. Between 1995 and 2013, the number of emigrants declined, but Armenia’s overall migration balance was negative. The majority of those leaving the country went to Russia, followed by the other states of the CIS.

Opis:
In this paper the author attempted to determine the most accurate mathematical model of the photovoltaic panel composed of a monolithic structure of series connected Copper Indium Diselenide (CIS) based solar cells, based on its actual measurement data. The purpose of this paper has been achieved by implementing the original applications which, using the methods of approximation, made it possible to design the final mathematical model of the tested panel, characterized by the minimum of error modelling. Using the known literature on the operation of similar facilities, the model parameters were determined directly from the collection of random measurement data; then the obtained models were verified by several different statistical methods. As a result, the best model was selected, based on the smallest dispersion of the theoretical values (simulated) calculated from the model relative to the actual measurements. The model will be used in practice in the future to evaluate the condition (inefficiency, use) of photovoltaic panels, what will be the theme of following articles.
W artykule autor dąży do określenia, w oparciu o rzeczywiste dane pomiarowe, najbardziej dokładnego modelu matematycznego panelu fotowoltaicznego, składającego się z monolitycznej struktury połączonych szeregowo ogniw fotowoltaicznych typu CIS. Cel pracy został osiągnięty poprzez wdrożenie oryginalnych aplikacji, które przy użyciu metod aproksymacji umożliwiły zaprojektowanie ostatecznego modelu matematycznego badanego panelu, charakteryzującego się minimalnym błędem modelowania. Wykorzystując literaturę tematu dotyczącą działania podobnych obiektów nieliniowych, parametry modelu zostały określone bezpośrednio z wcześniej zarchiwizowanych losowych danych pomiarowych. Następnie uzyskane modele zweryfikowano kilkoma różnymi metodami statystycznymi. W wyniku tego wybrano najlepszy model, oparty na najmniejszej dyspersji wartości teoretycznych (symulowanych) obliczonej z modelu w stosunku do rzeczywistych pomiarów. Otrzymany model zostanie w przyszłości zastosowany w praktyce do oceny stanu (niesprawności, zużycia) paneli fotowoltaicznych, co będzie tematem kolejnych artykułów.

We developed the mathematical model consist of cells sensitive and resistant to cis-platinum. The performed simulations suggest that the best strategy to prolong the patient lifetime after diagnosis is to keep the sensitive cells subpopulation at the constant level instead of killing all of them.

Opis:
In the yeast Saccharomyces cerevisiae the RER2 and SRT1 genes encode Rer2 and Srt1 proteins with cis-prenyltransferase (cis-PT-ase) activity. Both cis-PT-ases utilize farnesyl diphosphate (FPP) as a starter for polyprenyl diphosphate (dolichol backbone) formation. The products of the Rer2 and Srt1 proteins consist of 14-17 and 18-23 isoprene units, respectively. In this work we demonstrate that deletion or overexpression of SRT1 up-regulates the activity of Rer2p and dolichol content. However, upon overexpression of SRT1, preferential synthesis of longer-chain dolichols and a decrease in the amount of the shorter species are observed. Furthermore, overexpression of the ERG20 gene (encoding farnesyl diphosphate synthase, Erg20p) induces transcription of SRT1 mRNA and increases the levels of mRNA for RER2 and DPM1 (dolichyl phosphate mannose synthase, Dpm1p). Subsequently the enzymatic activity of Rer2p and dolichol content are also increased. However, the amount of Dpm1p or its enzymatic activity remain unchanged.

Opis:
Anticancer activity of cisplatin (cis-diamminedichloroplatinum) is believed to result from its interaction with DNA. The drug reacts with nucleophilic sites in DNA forming monoadducts as well as intra- and interstrand crosslinks. DNA-cisplatin adducts are specifically recognized by several proteins. They can be divided into two classes. One constitutes proteins which recognize DNA damage as an initial step of the nucleotide excision and mismatch repair pathways. The other class contains proteins stabilizing cellular DNA-protein and protein-protein complexes, including non-histone proteins from the HMG (high-mobility-group) family. They specifically recognize 1,2-interstrand d(GpG) and d(ApG) crosslinks of DNA-cisplatin adducts and inhibit their repair. Many HMG-domain proteins can function as transcription factors, e.g. UBF, an RNA polymerase I transcription factor, the mammalian testis-determining factor SRY and the human mitochondrial transcription factor mtTFA. Moreover, it seems that some proteins, which probably recognize DNA-cisplatin adducts non-specifically, e.g. actin and other nuclear matrix proteins, can disturb the structural and functional organization of the nucleus and whole cell. The formation of complexes between DNA and proteins in the presence of cisplatin and the changes in the cell architecture may account for the drug cytotoxicity.

Insect kinin analogues of the sequence Phe-Phe-ψ[CN4]-Ala-Trp-Gly-NH2 containing (L-Phe2,L-Ala3) and (L-Phe2,D-Ala3) stereochemical variants of the tetrazole moiety, a mimic of the type VI β-turn, demonstrate significant agonist and partial antagonist activity, respectively, in a cricket diuretic bioassay. A comparison of the solution conformations of these two stereochemical variants indicates a structural basis for their divergent bioactivities. The (D-Phe2,D-Ala3) stereochemical variant was synthesized and found to demonstrate significant agonist activity. The results further define stereochemical requirements for the diuretic activity of insect kinins in crickets and provide valuable information for the design of biostable analogues capable of disrupting digestive and diuretic processes in pest insects.

Opis:
In recent years, EU countries, including these from the Central Eastern European (CEE) region has recognised, that eco-innovation should be treated as strategic priority of their economies. The aim of this paper is to present a cross-country analysis of the connection between eco-innovation and its main drivers within firms from selected CEE countries (Bulgaria, Czech Republic, Romania) and Germany. The empirical part is based on micro-data for Community Innovation Survey (CIS) 2006-2008. Based on the results of stepwise regression between main policy actions sustaining innovation activity and eco-innovation performance we can conclude, that financial support for innovation activities has a rather limited role in promoting eco-innovation. At the same time enterprises from the CEE region regard environmental regulations as the most important drivers of eco-innovation. In Germany, a country ranked in the highest category in the Eco-Innovation Scoreboard, the variety of forces that influence eco-innovation is much more wide-ranging. This indicates that government actions should take a broader look and lay the more general bases fostering the model of a green growth.
