Aim. The comparison of the effect of hydrothermal conditions and various agricultural practices on the emission of CO 2 from chernozems in the Left-Bank Forest-Steppe of Ukraine. Methods. The dynamics of the intensity of carbon dioxide emissions from chernozem calcic (typical chernozem – in Ukrainian classifi cation) was studied during the growing season of 2011–2012. The observations were based on two fi eld experiments with various methods of soil till- age (6–7 years from the beginning of the experiment) and fertilization systems (21–22 years from the beginning of the experiment). Particularly, plowing at 20–22 cm, disking at 10–12 cm, cultivation at 6–8 cm and direct seeding using Great Plains drill were studied among the soil tillage methods. Mineral system (N 45 P 50 K 45 ), organic system (manure 8 t/ha) and combined organic-mineral system (manure 8 t/ha + N 45 P 50 K 45 ) were studied among fertilization systems. The intensity of CO 2 fl ux was determined using the non-stationary respiratory chambers by the alkaline absorption method, with averaging of the results during the day and the frequency of once a month. Results. During the warm period, the emission of carbon dioxide from the soil changes dynamically depending on temperature and humidity. The maximum of emission coincides with the periods of warm summer showers in June-July, the minimum values are characteristic for the late autumn period. The total emission losses of carbon in chernozems over the vegetation period ranged from 480 to 910 kg/ha and varied depending on the methods of tillage ± (4.0–6.0) % and fertilization systems ± (3.8–7.1) %. The changes in the intensity of CO 2 emission from the soil under different methods of soil tillage are associated with hydrothermal regime and the depth of crop residues location. The biggest difference is observed im- mediately after tillage, but in the spring period the differences are only 12–25 %, and after drying of the top layer of soil become even less. Direct seeding technology provides the greatest emission of CO 2 from chernozem, which is fa- cilitated by better water regime and more complete mineralization of plant residues on the soil surface. Annual losses of carbon are the least under disking of soil at 10–12 cm. The changes in the intensity of CO 2 emission from the soil under different fertilization systems are associated with the involvement of the additional organic matter from plant residues and manure to the microbiological decomposition. The greatest emission was observed under the organic- mineral fertilization system, which increased the loss of carbon by 7–8 % in comparison with the mineral system in the unfavorable hydrothermal year and by 11–15 % in the more favorable year. These differences are observed mainly during the fi rst half of the growing season when there is a clear tendency to increase the intensity of soil respiration. Conclusions. The hydrothermal conditions of the warm period of the year are decisive in the formation of the CO 2 emission fl ow from chernozems. Due to the improvement of agricultural practices, emissions might be reduced but not more that by 15 % of natural factor contribution.

Marriage is an important thing in the life of a woman. The importance that our society attaches to marriage is reflected in our literature and it is the central concern of Shashi Deshpade’s novels. In our society where girl learns early that she is ‘Paraya Dhan’, and she is her parents’ responsibility till the day she is handed over to her rightful owners. What a girl makes of her life, how she shapes herself as an individual, what profession she takes up is not as important as whom she marries. Marriage is the ultimate goal of a woman’s life. This paper attempts to probe into the problems of marriage through the protagonists of her novels where one enjoys the freedom of marriage and the other accepts the traditional marriage. Shashi Deshpade highlights the problems of marriage faced by middle-class people in finding suitable grooms for their daughters. This problem is well-illustrated through the characters of her novels. Since the girl’s mind over her childhood is tuned that she is another’s property, she tries to attach a lot of importance to it. it is indeed a tragedy that even in the modern age, Indian females echo the same sentiment where it was marriage which mattered most of them but not to the men. It is a beginning of females sacrifices in life that marriage brings to her. Shashi Deshpande encourages her female protagonists to rise in rebellion against the males in the family matters, instead she wants to build a harmonious relationship between man and woman in a mood of compromise and reconciliation.

In the modern age of globalization and modernization, people have become selfish and self-centered.  Feeling of sympathy and kindness towards poor people have almost bolted from the hearts of those who have richly available resources.  They leave needy people running behind their luxurious chauffer-driven cars.  Poor and marginalized people keep shouting for help for their dear ones but upper class people trying to show as if they did not hear any long distant sound crept into their eardrums.  This trauma, agony, pain and sufferings is explored in the novel, The Foreigner.

Die Kunst der Moderne, insbesondere die Lyrik, entwickelt eine eigene ästhetische Konzeption der Bewegung, die mit der klassischen Vorstellung der Bewegung als räumlicher Veränderung eines Körpers in der Zeit bricht. Baudelaires À une Passante, Rimbauds Bateauivre und Paul Valérys Le Cimetière marin sind drei paradigmatische Texte der französischen Moderne, in denen Bewegung als zeiträumliches Kontinuum reflektiert und in der Dynamik der Sprache materialisiert wird. Die moderne Kunst, so erweist sich, ist selbst Bewegung und stiftet Bewegung. Sie wird zu einer Kunst des Werdens, nicht der Substanz, zu einer Kunst der reinen sinnlichen Wahrnehmung, nicht des Begriffes, zu einer Kunst der diskontinuierlichen Erlebnisse, nicht der Erfahrung.<br><br>The art of the modern age, particularly the lyric poetry, develops an own aesthetic conception of the movement which breaks with the classic idea of the movement as a spatial change of a body in time. Baudelaires À une Passante, Rimbauds Bateau ivre and Paul Valérys Le Cimetière Marin are three paradigmatic texts of the French modern age, in which movement is reflected as a time-space-continuum and materialized in the dynamic of language. Modern art is itself movement and causes movement. It becomes an art of the development, not sub- stance, an art of pure sensory perception, not concept, an art of discontinuous adventures, not experience.
