    We present an analysis of Young Stellar Object (YSO) candidates towards the LDN 1188 molecular cloud. The YSO candidates were selected from the WISE all-sky catalogue, based on a statistical method. We found 601 candidates in the region, and classified them as Class I, Flat and Class II YSOs. Groups were identified and described with the Minimal Spanning Tree (MST) method. Previously identified molecular cores show evidence of ongoing star formation at different stages throughout the cloud complex.Comment: 4 pages, 4 figures, 2 table

    A termodinamika variációs elveinek alkalmazásai terén 2007 óta új kutatási vonal indult a reciprocitási relációk elfogadottságának felderítésére. A termodinamika mechanikai alkalmazásai terén: A termodinamika és a termodinamikai reológia eredményeinek, módszereinek propagálása és új alkalmazási területek felderítése. A termoelaszticitás új termodinamikai elméletének megalapozása. Az entrópiatranszport sűrűség formulájának általánosítása felveti a hő és a munka fogalmainak az általánosan elterjedtektől eltérő, a modern igényeknek is megfelelő értelmezését. Az elektromosan töltött test mechanikai mozgásegyenletének összehangolása az elektrodinamika elméletével. A hő klasszikus definiciója nem-egyensúlyi rendszerekben tarthatatlan. Az Onsager-Casimir-féle reciprocitási relációk sokkal általánosabb érvényűek, mint amit az ismert bizonyítások mutatnak. Az elektronikus eszközökben használt NiMH akkumulátorok termodinamikai modellezéséhez tervezett kísérletek előkészítése. (Nagyon nehézkesen haladok.) | A new line concerning the variational principles of thermodynamics has opened to find out the acceptance of the reciprocal relations since 2007. Applying thermodynamics in mechanics: Propagating the results and methods of thermodynamics and thermodynamic rheology and looking for new fields of applications. Foundation of a new thermodynamic theory for thermal stress. The reinterpretation of the entropy transport involves the reconsideration of the generally used ideas of heat and work to fit them to the modern demands. Fitting the equation of motion of a charged body to electrodynamics. The classical definition of heat can not be maintained out of equilibrium; correct modeling entropy flow can overrule their weakness. The Onsager-Casimir reciprocal relations are much more general then coming from the known proofs. Preparing experiments with rechargeable batteries. (I cam manage but hardly.) Further plans for publications and research: To go on with fitting thermodynamics and the theory of electromagnetic radiation. Investigating the structure and possible generalizations of the Onsager-Casimir reciprocal relations. To fit thermodynamics and quantum theory

    14th-16th-century Danube floods and long-term water-level changes in archaeological and sedimentary evidence in the western and central Carpathian basin : an overview with documentary comparison

    In the present paper an overview of published and unpublished results of archaeological and sedimentary investigations, predominantly reflect on 14th-16th-century changes, are provided and evidence compared to documentary information on flood events and long-term changes. Long-term changes in flood behaviour (e.g. frequency, intensity, seasonality) and average water-level conditions had long-term detectable impacts on sedimentation and fluvio-morphological processes. Moreover, the available archaeological evidence might also provide information on the reaction of the society, in the form of changes in settlement organisation, building structures and processes. At present, information is mainly available concerning the 16th, and partly to the 14th-15th centuries. These results were compared to the available documentary evidence on 14th-16th century Danube floods occurred in the Carpathian Basin

    Impact of Economic and Financial Crisis on Human Resource Function in Four Eastern- European Countries in Light of an Empirical Research in 2009

    Get PDF
    When the crisis broke out in October 2008, the four countries (Bulgaria, Hungary, Romania and Slovakia) examined were in different situations, and, consequently, the governments of these countries reacted at different times. They did so, however, in very similar ways. Nevertheless, it is particularly important to know how their companies reacted to the crisis, and our study aims to find out what actions companies from these selected countries plan to take concerning the field of Human Resource Management (HRM) in the present financial and economic crisis. With a brief review of the literature, we demonstrate the role of HR in a period of depression, and then we present the findings of our empirical research, which was conducted from November 2008 to February 2009.Keywords: Human Resource Management, Crisis, Bulgaria, Hungary, Romania and Slovakia.

    Moments of the superdiffusive elephant random walk with general step distribution

    Get PDF
    We consider the elephant random walk with general step distribution. We calculate the first four moments of the limiting distribution of the position rescaled by nαn^\alpha in the superdiffusive regime where α\alpha is the memory parameter. This extends the results obtained by Bercu.Comment: 11 page
