Abstract: The chemical and physical properties of molecular clusters can heavily depend on their size, which makes them very attractive for the design of new materials with tailored properties. Deriving the structure and dynamics of clusters is therefore of major interest in science. Weakly bound clusters can be studied using conventional spectroscopic techniques, but the number of lines observed is often too small for a comprehensive structural analysis. Impulsive alignment generates rotational wavepackets, which provides simultaneous information on structure and dynamics, as has been demonstrated successfully for isolated molecules. Here, we apply this technique for the firsttime to clusters comprising of a molecule and a single helium atom. By forcing the population of high rotational levels in intense laser fields we demonstrate the generation of rich rotational line spectra for this system, establishing the highly delocalised structure and the coherence of rotational wavepacket propagation. Our findings enable studies of clusters of different sizes and complexity as well as incipient superfluidity effects using wavepacket methods.
Sta iatikyb s literatūros teologija: id jos ir problemika | The theology of orthodox literature: ideas and problems
Gediminas Mikelaitis
Literatura , 2012,
Abstract: The articles presents an overview of the first post- Soviet attempts by the Russian literature scholars to consider the links between the ideas of the Ortho-doxy and literature. Attempts are put, besides defin-ing the Christian stratum of the Russian culture, to establish the methodology of the research. The ar-ticle highlights the unique character of the theology of the Orthodox literature, mainly anchored to the ideas of the Russian religious philosophy reflected in the works of the Russian thinkers and writers as Vladimir Solovyov, Nikolai Berdyaev, Dmitri Mer-ezhkovski, Fyodor Dostoyevsky, Andrei Bely and others. The article discusses the theologemes char-acteristic of the Orthodox literature: the depiction of Sophia, theurgic parameter, the ontological character of creation, performativeness, religious anthropol-ogy of Dostoyevsky. The uniqueness of the relation-ship between the Orthodoxy and literature is defined by demonstrating its link with religious philosophy, the aesthetic parameter of the existence, the role of religious ideas in literature, and the significance of theurgic aesthetics.
Literatūros teologija: identiteto paie kos | Literaturtheologie: Identit tssuchen
Gediminas Mikelaitis
Literatura , 2006,
Abstract: Die sich gerade herausbildende Literaturtheologie basiert vor allem auf einer jahrhundertealten Tradition. Aus der Philosophie und der Literaturwissenschaft der Neuzeit übernimmt sie eine kritische Reflexion der Religionsph nomene und der gesellschaftlichen Ansichten. Dank ihrer methodologischen Flexibilit t und der F higkeit, religi se Erfahrungen oder die transzendente Dimension des Lebens vielseitiger und mit mehr Einsicht zu bewerten, l st die Literturtheologie im Grunde genommen den in der ersten H lfte und in der Mitte des XX. Jahrhunderts g ngigen Fachbegriff christliche Literatur ab. Als eine Methode der Literaturforschung er ffnet die Literaturtheologie neue M glichkeiten zur Erschlie ung neuer semantischer und struktureller Schichten im Gefüge der litauischen Literatur.
Vydūnas ir jo dramos: tapatyb s, lū iai ir i kreiptos figūros | Vydūnas and his dramas: identity, turning-points and distorted figures
Gediminas Karoblis
Literatura , 2006,
Abstract: In this research paper the play Probo i e liai [The Shadows of Forefathers] written by famous Lithuanian philosopher Vidunas is analysed in details. Besides classical critical analysis of the text, deconstruction as the method is used as well, making the meanings intended by the author reversible. The innovation of the research is the third methodical part of it – the hermeneutic-phenomenological protocol. The results and the process of the research are described concerning the dynamics of time and problem solving. What is most often left undisclosed in a real research – its temporal duration, findings and disappointments, here is very strongly put on the surface of the consciousness. The researcher in this way is disclosed as the embodied and the embedded agent in the process of research. Analysis of the direct object of the research – the play Probo i e liai – along these methodical lines of structural deconstruction and hermeneutic-phenomenological protocol clarifies the figure of Visuomis as a non empathic philosopher. This predicate might be projected to the whole spiritualistic philosophy of Vidunas. Much discussed philosophy of the body developed by Vidunas is strongly questioned, analysing a few examples from the life of Vidunas himself: the early childhood and the turningpoint event of his falling from the ship. The whole body of Vidunas in this event was shocked, as he describes himself, and Vidunas understood in the new light the relevance of the body in the experience of the world. Does this event might be considered as the “Lithuanian version” of the collision of God of the Philosophers and God of Abraham, Jacob and Isaac?

Comment on "Quantum Theory of Dispersive Electromagnetic Fields"
Gediminas Juzeliunas
Physics , 1999,
Abstract: Recently Drummond and Hillery [Phys. Rev.A 59, 691(1999)] presented a quantum theory of dispersion based on the analysis of a coupled system of the electromagnetic field and atoms in the multipolar QED formulation. The theory has led to the explicit mode-expansions for various field-operators in a homogeneous medium characterized by an arbitrary number of resonant transitions with different frequencies. In this Comment, we drawn attention to a similar multipolar study by Juzeliunas [Phys. Rev.A 53, 3543 (1996); 55, 929 (1997)] on the field quantization in a discrete molecular (or atomic) medium. A comparative analysis of the two approaches is carried out, highlighting both common and distinctive features.

Science – Future of Lithuania , 2009, DOI: 10.3846/120
Abstract: The results of experimental investigation of upstream installation effects on metrological characteristics of the electromagnetic and turbine flow sensors of the nominal diameter DN50 are presented. The influence of inlet pipe diameter and influence of gasket diameter on accuracy of flow sensors were investigated. It was found that the most sensitive flow sensor on above mentioned flow disturbances are the turbine ones. The supplementary error caused by reduced inlet pipe diameter can increased up to 8% meanwhile reduction of gasket inner diameter increases supplementary error up to 25%. Investigated electromagnetic flow sensors are less sensitive to flow disturbances and supplementary error in the worse case was not more than ± 2,0%.

Gediminas Bal?ius
Environmental Research, Engineering and Management , 2012, DOI: 10.5755/j01.erem.60.2.863
Abstract: Controlling chemical substances and correct evaluation of danger and risk caused by them, based on scientific research are necessary in order to keep environment and public health safe. Regulation signed by European Parliament and Council to control registration, evaluation, authorization and limitation of chemical substances (REACH) is the main juridical act from the new European Union‘s policy regarding regulation of chemical substances. Objective of this research was to gather and analyze data regarding phthalates used in Lithuania‘s industry, to present data on its environmental levels in surface water, sediments, sewage treatment plant effluents, and to discuss the needs for the human biomonitoring in Lithuania. The amount of diethylhexyl phthalate yielded to Lithuania‘s industry and market, incresed 65 times from 3,7t in 2003 to 240,81t in 2007. DEHP concentrations in Lithuania in wastewater exceeded regulated annual average maximum allowable concentrations up to 27 times and maximum allowable concentrations up to 13 times. High environmental concentrations of phthalates pointed out to the needs of establishment of permanent human biomonitoring in Lithuania. DOI: http://dx.doi.org/10.5755/j01.erem.60.2.863
