Impact of Simulated Airborne Soot on Maize Growth and Development  [PDF]
Angela Anda, Berndett Illes
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.38092
Abstract: Various effects of the dry deposition of soot on maize were investigated in Keszthely (Hungary) in two consecutive years. In order to be able to study a wider range of weather conditions, some of the plants were placed in a Thornthwaite-Matter type evapotranspirometer and given ad libitum water supplies. Pollution with airborne black carbon was simulated throughout the season by distributing rates of 3 g?m–2 a week using a motorised dust sprayer. Among the plant growth parameters, the leaf area index was increased by 3% - 14%, depending on the year, suggesting that the plants were able to absorb the carbon settling on the leaves. The black carbon reduced the albedo of the canopy by 17.5% - 21.8%, depending on the year, forcing the polluted maize to absorb more energy. Part of this surplus energy was utilised for increased evapotranspiration (3.9% and 11% in the two years) and to raise the surface temperature of the canopy by 1℃ - 2℃ during the mid-day hours. The effect of the contamination on maize was more intense in the hot, dry year. The unfavourable effect of soot on maize fertilisation could be observed as a significant increase in the number of deformed ears, leading to a reduction in grain dry matter. The reduction in dry matter yield for polluted maize grown with irrigation in the evapotranspirometer was far less severe than that on non-irrigated plots, suggesting that irrigation was the most obvious solution for mitigating the negative effects of contamination with airborne soot.
Modeling maize response to climate modification in Hungary
Angela Anda
Communications in Biometry and Crop Science , 2006,
Abstract: Modeling provides a tool for a better understanding of the modified plant behaviour that results from various climatic differences. The present study provides new information about the physiological processes in maize (Zea mays L.) in response to climatic changes. The aim was to help local farmers adapt to climate modifications in Hungary and mitigate the future consequences of these changes. A simulation model was applied to estimate the possible feedback on crop properties and elevated CO2. Increased CO2 and warming increased the ratio of energy converted into sensible heat. At canopy level, warming and elevated CO2 strengthened the influence of an external rise in air temperature. It was cooler inside the stand, as the canopy was able to compensate for external warming. Doubled CO2 concentration had a positive influence on photosynthesis when rainfall remained unchanged. Precipitation shortage decreased the positive effects of warming and elevated CO2. Considering the sensitivity of the photosynthetic process to meteorological factors, a gain in maize production with climate modification is not probable in Hungary.
An Uncontested Party Period of the Turkey Republic  [PDF]
Elnur Hasan Mikail, Anda? Karabulut
Open Journal of Political Science (OJPS) , 2016, DOI: 10.4236/ojps.2016.62023
Abstract: In an environment in which faction in the Turkish National Assembly increased and there occurred the need of political parties in politics, Mustafa Kemal announced a declaration to the press in 6 December 1922 that he would establish a political party named “People’s Party”. In 8 April 1923, Mustafa Kemal, in the capacity of the chairman of Anatolia and Rumelia Defense of Law Community, announced a declaration. This election declaration, at the same time, is in the form of a schedule preparation for the upcoming party. Later on, Mustafa Kemal and the congressmen in support of the establishment of the party started the preparations for the regulation.
The Political Developments in Turkey during Ataturk’s Period  [PDF]
Elnur Hasan Mikail, Anda? Karabulut
Open Journal of Political Science (OJPS) , 2017, DOI: 10.4236/ojps.2017.74040
Abstract: It has been understood that during the Seyh Sait Rebellion in East Anatolia, the Prime Minister Fethi Bey had a talk with the Leaders of this Party, that he had warned them and suggested to moderate or totally remove the Party organizations there. As this revolt became a dangerous face, the Government legalized the proposed Law concerning “the Religion must not be an instrument for the Politics” on the 25th of February 1925. However, after the questioning proposal in the C.H.P group with 18 signs concerning the facts in the East, there was held a vote of confidence for the Government and the cabinet resigned as a mistrust result for Fethi Bey with 60 dissential votes from 94 total votes. Ismet Pasa was charged with the duty to set up a new cabinet. In view of the Seyh Sait Rebellion, it has been seen that the Progressive-minded Party supported the cabinet of Fethi Bey and moreover, that the Leader Kazim Karabekir Pasa responded the martial Law decision of this Government as constructive and that he condemned this Rebellion by saying that: those who put the national presence in danger by procuring the religion as an instrument are deserving curse. This behaviour is infidelity to the country about the Rebellion.
Development of Mathematics Competences in Higher Education Institutions
Anda Zeidmane
International Journal of Engineering Pedagogy , 2013, DOI: 10.3991/ijep.v3is2.2394
Abstract: The changes in society require revision of the content of higher education. Mathematics as a classical subject has played an important part in higher education until now, especially in engineering education. The introduction of mathematics IT programmes (MathCad, MathLab, Matematica, Maple…) in labour market caused the reduction of the practical application of the classical mathematics, therefore it is important to draw attention to the development of mathematical competences. The theoretical part of the paper deals with the notion of competence, its aspects and types, considers the question of the essence of mathematics, examines general competences driven teaching of mathematics, describes organisational model underlying the curriculum in mathematics that is based on the division of the content of mathematics into levels. The paper describes the main issues of the development of teaching of mathematics discussed by European mathematicians (SEFI Math Working Group). The paper presents the results of the ERDF project “Cross-border network for adapting mathematical competences in the socio-economic development (MatNet)”, which studied the role of mathematics in today's labor market in the context of modern education (“Mathematics in professional activities”) and the role of mathematics in studies at the Latvia University of Agriculture (LUA) and Siauliai University in Lithuania (“Mathematics in professional studies”). The paper describes the LUA experience in integration of IT programmes in the study process of mathematics, as well as the experience of organizing the self-directed study of mathematics’ practical application based on didactic approach and e-learning features.
Rationaliy and Utility of Evaluation Reseach in Policy Making
Anda Lake
Studies of Transition States and Societies , 2011,
Abstract: In this article, the author explores the issues associated with the practical significance of evaluation research in the policy making environment of Latvia. Sporadic, selective and rare use of the results of evaluation research is viewed as the central issue of the paper. The objective of this article is to reveal the connection between the action strategy of the groups involved in the implementation of evaluation research and manifestations of practical significance of evaluation. Implementation, utilisation and practical importance of evaluation research are examined not only in relation to rational action strategies of the groups, but also in relation to the understanding of the concept of practical significance of evaluation research. The theoretical framework of the article is based on the conceptual understanding of J. Habermas’ purposive rationality and communicative rationality, as well as C. H. Weiss’ understanding of practical utilisation of evaluation (the instrumental and enlightened models). The practical importance of evaluation research as well as action strategies of implementing evaluation research are studied empirically in the form of qualitative interviews. The author concludes that the rational action strategy (typical of the Latvian policy making environment) of the groups involved in evaluation is not readily compatible with the evaluation approach that focuses on practical utilisation. The lack of communicative rationality in the action strategy of the interacting and involved groups substantially diminishes the role of evaluation research in the identification and implementation of the most effective models of solving social issues in policy making in Latvia.

Mathematics , 2010,
Abstract: In this paper we characterize all the lexsegment ideals which are normally torsion-free. Our characterization is given in terms of the ends of the lexsegment. We also prove that the property of being normally torsion-free is equivalent to the property of the depth function of being constant.
A note on the subword complexes in Coxeter groups
Anda Olteanu
Mathematics , 2008,
Abstract: We prove that the Stanley--Reisner ideal of the Alexander dual of the subword complexes in Coxeter groups has linear quotients with respect to the lexicographical order of the minimal monomial generators. As a consequence, we obtain a shelling order on the facets of the subword complex. We relate some invariants of the subword complexes or of their dual with invariants of the word. For a particular class of subword complexes, we prove that the Stanley--Reisner ring is a complete intersection ring.
