Tamás Erdélyi, Anikó Bohács, Krisztina Vincze, Zsuzsanna Kováts, Veronika Sárosi, András Sinkovicz, Gy?rgy Balázs, Veronika Müller
Case Reports in Clinical Medicine (CRCM) , 2014, DOI: 10.4236/crcm.2014.312135
Abstract: Lymphangioleiomyomatosis (LAM) is a rare disease that affects women, especially in child-bearing age. Clinical manifestations include angiomyolipoma, pneumothorax, chylothorax, cystic changes of lungs and progressive pulmonary failure. In this article, we report a case of lung transplantation (LuTX) for end stage pulmonary LAM and the treatment of angiomyolipoma showing growth after LuTX resulting in complete remission with combination therapy of everolimus and tacrolimus.
SMALL BUSINESSES IN SOUTH AND WESTERN HUNGARY IN THE NINETIES - RESULTS OF A SOCIOLOGICAL SURVEY
Ern? KOVáCS,Zsuzsanna BACSI
Journal of Central European Agriculture , 2001,
Abstract: The objectives of the research are to analyse the main features of small businesses of South and West Hungary, to identify the main tendencies of their operation and development and to determine the main motivating factors in their business management processes. The area under examination covers rural county Zala, rural county Somogy, and the settlements located by the Western shore of lake Balaton. The main findings: the fast increase in the number of the small and medium size enterprises is due to the loss of the employment possibilities, the inclination and resources of vocationally trained workers to establish their own businesses including family traditions, the desire to achieve tax reduction and income maximisation, and higher incomes. Difficulties are caused by the lack of available capital. Enterprises not turning back part of their gains into the business cannot provide sufficient income for the family.
Consumer Behaviour Model on the Furniture Market
BEDNáRIK, éva,PAKAINé KOVáTS, Judit
Acta Silvatica & Lignaria Hungarica , 2010,
Abstract: This study introduces the furniture purchasing behaviour model. The study describes thebehaviour model and characteristics of decision making and the environmental factors affecting theindividuals besides emphasising the family character of furniture purchase. We introduce a chapterfrom the primary research verifying the model that analyses the validity of customer behaviour trendsdefined as elements of the impersonal environment on the furniture market. We touch on our lifestylebased segmentation model which is elaborated in our work in detail. The method of primary researchis quantitative, personal interview. While working out our research model we applied a method thatenables multi-level cross-section and cohort analyses. Our work has verified the need for trendresearches on the furniture market so we suggest the construction and the near-future launch of a trendresearch system consisting of several modules that reveals the specific factors on the furniture marketbesides verifying the validity of general behaviour trends.
Ratio tests for change point detection
Lajos Horváth,Zsuzsanna Horváth,Marie Hu?ková
Mathematics , 2008, DOI: 10.1214/193940307000000220
Abstract: We propose new tests to detect a change in the mean of a time series. Like many existing tests, the new ones are based on the CUSUM process. Existing CUSUM tests require an estimator of a scale parameter to make them asymptotically distribution free under the no change null hypothesis. Even if the observations are independent, the estimation of the scale parameter is not simple since the estimator for the scale parameter should be at least consistent under the null as well as under the alternative. The situation is much more complicated in case of dependent data, where the empirical spectral density at 0 is used to scale the CUSUM process. To circumvent these difficulties, new tests are proposed which are ratios of CUSUM functionals. We demonstrate the applicability of our method to detect a change in the mean when the errors are AR(1) and GARCH(1,1) sequences.

Knowledge and Management of Aquatic Ecosystems , 2010, DOI: 10.1051/kmae/2010028
Abstract: In this study glochidia as most sensitive life-stage of bivalves were used to evaluate the toxicity of copper, zinc and lead. Sensitivity of three species, Anodonta anatina, Pseudanodonta complanata and Unio tumiduswere compared to copper and zinc, based on 24 and 48 h LC50s. The copper 24 h LC50 showed the lowest value (26.8 μg·L-1) for Unio tumidus glochidia. After 48 h exposure, close LC50 values, 18.9 and 19.0 μg·L-1, were recorded for A. anatina and U. tumidus glochidia, respectively. U. tumidus glochidia exhibited the highest sensitivity to zinc (48 h LC50 = 134.2 μg·L-1) followed by P. complanata (48 h LC50 = 201.6 μg·L-1) and A. anatina (48 h LC50 = 233.5 μg·L-1). Toxicity of lead to P. complanata glochidia was estimated, 24 and 48 h LC50s of lead to 374.6 and 260.8 μg·L-1, respectively. No observed effect concentrations (NOECs) for the tested metals exhibited species differences. All NOECs exceeded environmental quality standards (EQS), therefore these species are at risk only in such European freshwaters which have extreme concentration of these metals. Synergistic effect was reported for the combinations of Cu + Zn and Cu + Pb, additive effect was reported for Zn + Pb. Dans cette étude, les glochidies comme stade de vie le plus sensible de bivalves ont été utilisées pour évaluer la toxicité du cuivre, du zinc et du plomb. La sensitivité de trois espèces, Anodonta anatina, Pseudanodonta complanata et Unio tumidus, aux cuivre et zinc a été comparée, à partir des LC50 24 et 48 h. La LC50 24 h du cuivre présente la valeur la plus basse (26,8 μg·L-1) pour les glochidies de Unio tumidus. Après 48 h d’exposition, des valeurs LC50 proches (18,9 et 19,0 μg·L-1) ont été enregistrées pour les glochidies de A. anatina et U. tumidus respectivement. Les glochidies de U. tumidus montrent la sensibilité la plus forte au zinc (48 h LC50 = 134,2 μg·L-1) suivie de P. complanata (48 h LC50 = 201,6 μg·L-1) et A. anatina (48 h LC50 = 233,5 μg·L-1). La toxicité du plomb vis à vis des glochidies de P. complanata a été estimée : LC50 24 et 48 h respectivement 374,6 et 260,8 μg·L-1. Les concentrations sans effet observé (NOECs) pour les métaux testés montrent des différences selon les espèces. Toutes les NOEC sont au-dessus du standard de qualité environnementale (EQS), par conséquent ces espèces ne seront à risque que dans les eaux douces européennes où les concentrations de ces métaux seraient extrêmes. Un effet synergique est constaté pour les combinaisons Cu + Zn et Cu + Pb, un effet additif pour Zn + Pb.
Social Problems of the Most Disadvantaged Southern Transdanubian Micro-Regions in Hungary
BERNADETT GáLOSI-KOVáCS,ZSUZSANNA M. CSáSZáR,TIBOR ELEKES
Romanian Review of Regional Studies , 2011,
Abstract: There are the so called most disadvantageous or MD micro-regions. The Hungarian government and the regional development institution system has worked out an own development programme for the improvement of these regions. The Southern Transdanubian Regional Development Council was established in 1998.The investigation focuses on the 8 most disadvantageous micro-regions of Southern Transdanubia. The micro-regional level in Hungary was determined on statistical and not on administrative consideration. The degree of social-economic underdevelopment under Hungarian circumstances is reflected by indicators of economy, infrastructure, society, sociality, and employment. The most disadvantaged micro-regions are qualified as beneficiary micro-regions. The 8 micro-regions of the Southern Transdanubian related to environmental development can be subsidized in the framework of the regional operational programme from the presumable resources of the micro-regions: economic development (business infrastructure), settlement development (function-expanding settlement development), environmental development (sewage, water management).

Abstract: In addition to its mass concentration, the health effects of urban particulate matter may depend on its particle size distribution and chemical composition. Yet air pollution regulations rely on exclusively bulk PM10 concentration measurements, without regard to their potentially different health effects under different conditions. Aerosols from various sources are well known to contain a plethora of toxic, carcinogenic, mutagenic or teratogenic constituents such as heavy metals and polycyclic aromatic hydrocarbons. Extensive public health studies established the link between mass concentrations of PM2.5 / PM10 and health problems within the population. However, little is known about the relative importance of PM from different sources and the effect of seasonality on the toxicity. Here we present the application of a simple and sensitive method for the direct assessment of the overall ecotoxicity of various PM2.5 / PM10 samples collected on filters. The method is based on the Vibrio fischeri bioluminescence inhibition bioassay that has been standardized for solid samples, representing a relevant biological exposure route. Direct emission samples proved to be significantly more ecotoxic than photochemically processed aerosol, thus marked differences were observed between the ecotoxicities of urban PM10 in summer and winter. These effects of urban PM10 may be useful supplementary indicators besides the mass concentrations of PM2.5 / PM10 in cities.
Initiation and Regulation of CNS Autoimmunity: Balancing Immune Surveillance and Inflammation in the CNS  [PDF]
Melissa G. Harris, Zsuzsanna Fabry
Neuroscience & Medicine (NM) , 2012, DOI: 10.4236/nm.2012.33026
Abstract: While the central nervous system (CNS) was once thought to be immune privileged, more recent data support that certain areas of the healthy CNS are routinely patrolled by immune cells. Further, antigen drainage is another means by which the adaptive arm of the immune system can gain information about the health of the CNS. Altogether these ensure that the CNS is not beyond the scope of immune protection against viruses and tumors. However, immune surveillance in the CNS has to be tightly regulated, as CNS autoimmune disease and inflammation may arise from increased immune cell infiltration. In this review we discuss the concept and implications of CNS immune surveillance and introduce the CNS antigen-presenting cells (APCs) that potentially regulate neuroinflammation and autoimmunity. We also discuss novel animal models in which CNS disease initiation and the role of APCs in disease regulation can be tested.

Physics , 2007, DOI: 10.1021/jp075204h
Abstract: C60-C8H8 and C70-C8H8 are prototypes of rotor-stator cocrystals. We present infrared and Raman spectra of these materials and show how the rotor-stator nature is reflected in their vibrational properties. We measured the vibrational spectra of the polymer phases poly(C60C8H8) and poly(C70C8H8) resulting from a solid state reaction occurring on heating. Based on the spectra we propose a connection pattern for the fullerene in poly(C60C8H8), where the symmetry of the C60 is D2h. On illuminating the C60-C8H8 cocrystal with green or blue light a photochemical reaction was observed leading to a similar product to that of the thermal polymerization.

Physics , 2010,
Abstract: The oscillator strengths of the $H^+_2$ molecular ion, $1s\sigma_{g}-2p\sigma_{u}$, $1s\sigma_{g}-2p\pi_{u}$ are calculated within the Born-Oppenheimer approximation. The variational expansion with randomly chosen exponents has been used for numerical studies. The oscillator strengths obtained for the transitions $1s\sigma_{g}-2p\sigma_{u}$, $1s\sigma_{g}-2p\pi_{u}$ of $H^+_2$ are accurate up to ten significant digits. Results are given for the internuclear distances between 0.10 and 20.0 a.u.
