Published: July 2014

Abstract
The article describes the problem of selection of heat treatment parameters to obtain the required mechanical properties in heat- treated bronzes. A methodology for the construction of a classification model based on rough set theory is presented. A model of this type allows the construction of inference rules also in the case when our knowledge of the existing phenomena is incomplete, and this is situation commonly encountered when new materials enter the market. In the case of new test materials, such as the grade of bronze described in this article, we still lack full knowledge and the choice of heat treatment parameters is based on a fragmentary knowledge resulting from experimental studies. The measurement results can be useful in building of a model, this model, however, cannot be deterministic, but can only approximate the stochastic nature of phenomena. The use of rough set theory allows for efficient inference also in areas that are not yet fully explored.

Authors: Jelínek P. , Adámková E. 
Published: July 2014

Abstract
Development of salt cores prepared by high-pressure squeezing and shooting with inorganic binders has shown a high potential of the given technology even for high-pressure casting of castings. Strength, surface quality of achieved castings, and solubility in water become a decisive criterion. The shape and quality of grain surface particularly of NaCl - cooking salts that can be well applied without anticaking additives has shown to be an important criterion. Thus the salt cores technology can cover increasingly growing demands for casting complexity especially for the automobile industry.

Abstract
Bentonite is clay rock, which is created by decomposition of vulcanic glass. It is formed from mixture of clay minerals of smectite group, mainly montmorillonite, beidellite and nontronite. Its typical characteristics is, that when in contact with water, it intensively swells. First who used this term was W.C. Knight in 1887. The rock had been named after town Fort Benton in American state Montana. For its interesting technological properties and whiteness has wide technological use. Bentonite is selectively mined and according to its final use separately modified, which results in high quality product with specific parameters.
In the beginning of 21st century belong bentonite moulding mixtures in foundry to always perspective. Mainly increased ratio of ductile cast iron castings production cannot be ensured without the need of quality bentonite. Great area of scope remains to further research of moulding materials, which return also to bentonite producers.
A first record of late Middle Permian actinopterygian fish from Anatolia, Turkey
Authors: Hoşgör Izzet , Štamberg Stanislav 
Published: July 2014

Abstract
The Middle-Upper Permian of the Gomaniibrik Formation, of the Tanin Group, in south-east Anatolia, close to the Iraq border, yielded moderately preserved fish remains. Two species, Palaeoniscum freieslebeni and Pygopterus cf. nielseni, known so far only from the Upper Permian deposits of the Zechstein Basin in western Central Europe, were recognised. This late Middle Permian Anatolian record significantly widens the geographical range of these actinopterygians into the equatorial Palaeotethys Realm.
The Change of Printouts' Quality Depending on Pressure of a Blanket Cylinder Against an Impression Cylinder and a Plate Cylinder in Offset Machine
Authors: Jurkiewicz Agnieszka , Pyr'yev Yuriy 
Published: July 2014

Abstract
According to lots of books, the pressure in offset printing affects the optical density and the quality of printouts. One of the quality parameters is a tone value increase. An advantage of our research method is obtaining printing effects for different pressures on one printout, thus meaning for identical printing conditions. We obtained the same printing conditions through using different amounts of underlay sheets fixed to the blanket cylinder, under a blanket. The pressure was increased from optimal settings - in accordance with the machine manufacturer’s recommendation. The test printouts were printed using Adast Dominant 515, on a coated and an uncoated paper. The optical density value was measured on the tone value scale from 10% to 100% stepping regularly by 10%. For this scale the tone value increase was computed. The research shows that for both types of paper the optical density and the tone value increase changes not very much above the optimal pressure recommended by the machine manufacturer. A difference in the optical density and in the tone value increase is bigger for coated paper than for uncoated paper. Changes in these two parameters are negligible in places where used form 0 to 4 underlay sheets and are quite significant in the place where 5 underlay sheets were.

Published: July 2014

Abstract
The paper presents the strategy for identifying the shape of defects in the domain defined in the boundary value problem modelled by the nonlinear differential equation. To solve the nonlinear problem in the iterative process the PIES method and its advantages were used: the efficient way of the boundary and the domain modelling and global integration. The identification was performed using the genetic algorithm, where in connection with the efficiency of PIES we identify the small number of data required to the defect’s definition. The strategy has been tested for different shapes of defects.

Authors: Dominik Ireneusz , Kaszuba Filip , Kwaśniewski Janusz 
Published: July 2014

Abstract
In this paper, a mathematical model of electromechanical transduction of Ionic Polymer-Metal Composites is presented. The aim of the research was to create a physics-based, geometrically scalable model to use in control systems. The relation between actuating voltage and the tip displacement was described with a transfer function. The model is derived from the basic physical properties of researched materials. To calculate the final transfer function, two impedance models are considered - with and without neglecting the resistance of the metal electrodes. In this paper, the model with non-zero electrode resistance is calculated. Later, the model is simplified (taking the physical properties into account) and the numerical values based on the parameters of the samples are calculated. The simplifications allow the model to predict the response to low-frequency sine wave actuation. The frequency-domain characteristics of the samples were created experimentally and compared to the model. The results have proven the accuracy of the model.

Authors: Man A. , Muntean P.E. , Mare Anca 
Published: July 2014

Abstract
Aim: To present the etiology of bacteremic syndromes and antibiotic susceptibility of blood culture isolates from a Romanian county hospital, as well as their distribution within different wards.
Methods: We retrospectively analyzed the blood culture data collected from patients hospitalized in the County Emergency Clinical Hospital of Tirgu Mures over a period of two years. We followed aspects regarding the identified bacterial species, their distribution by sex, age groups and wards, the spectrum of resistance to antibiotics and main resistance phenotypes.
Results: Most positive samples came from ICU, nephrology and urology. The most isolated bacteria were coagulase-negative staphylococci, Escherichia coli, and Staphylococcus aureus. All isolates showed a high resistance to most classes of antibiotics, staphylococci being susceptible to glycopeptides, oxazolidinones and glycylcyclines, and the enterobacteria to aminoglycosides and carbapenems. The resistance in non-fermentative bacilli exceeded 80% to most classes of antibiotics. The methicillin-resistance was 36% for coagulase-negative staphylococci and 82% for Staphylococcus aureus; the percentage of extended-spectrum beta-lactamase producing strains was 30%.
Conclusions: The etiology of bacteremic syndromes is specific to the ward profile, the Staphylococcus spp. being primarily isolated from wards where invasive procedures are frequently performed, while the enterobacteria from urology and nephrology wards. The level of antibiotic resistance is higher in surgery and ICU wards, with also higher percentage of resistance phenotypes than in medical wards.

Published: July 2014

Abstract
Introduction: A low degree of inflammation has been associated with complications in pregnancies, including preeclampsia (PE). The aim of our study was to determine the serum values of high sensitivity C Reactive Protein (hs-CRP) and Interleukin-6 (IL-6) in the first and second trimesters of pregnancy in pregnant women with risk factors for the development of PE, and to evaluate their relevance for the prediction of this disorder.
Material and methods: We performed a prospective longitudinal study on 120 pregnant women, who were divided based on the pregnancy evolution, into two groups: group I - 26 pregnant women who developed preeclampsia and group II - 94 pregnant women with physiological evolution of pregnancy.
Results: Our study has shown an increase in serum levels of hs-CRP and IL-6 in the first and second trimester of pregnancy in patients from group I, significant values being revealed only in the second trimester of pregnancy. The predictive power of the selected inflammatory markers was significant only for values of hs-CRP in the second trimester of pregnancy, while the association with IL-6 increased the prediction.
Conclusions: Increased values of hs-CRP and IL-6 in the second trimester of pregnancy are associated with higher risk for preeclampsia, however the study provided only a modest efficiency of the prediction capacity.

Authors: Rusu Aura , Hancu G. , Gyéresi Á. 
Published: July 2014

Abstract
Introduction: Antibacterial quinolones class comprises a series of synthetic antibacterial agents, following the model of nalidixic acid. Because of their common 6-fl uorosubtituent on the quinolone ring, fluroquinolones are the most potent analogues with extended spectrum of activity and great pharmacokinetic properties. The applicability of capillary zone electrophoresis for the separation of fl uoroquinolones in acidic background electrolyte has been studied, our aim being the development of a capillary zone electrophoresis method for the simultaneous separation of six fl uoroquinolones and also to optimize the analytical conditions. The six studied fl uoroquinolones were ciprofloxacin, enoxacin, enrofloxacin, moxifloxacin, ofloxacin and sarafloxacin.
Material and methods: Preliminary, we studied the electrophoretic behavior of six fluoroquinolones in an acidic pH, which highlighted the possibility of developing a separation method in this area of pH. Electrophoretic parameters infl uencing separation performance were studied and optimized.
Results: A fast and reliable method has been developed, using a background electrolyte containing 100 mM phosphoric acid and the following conditions: applied voltage: + 25 kV, temperature: 20°C, injection pressure 30 mbar - 5 sec, UV detection at 280 nm, capillary: 60 cm (52 cm effective length) x 50 μm, analyte concentration: 167 μg/ml. The separation of the studied fl uoroquinolones was achieved in less than 8 minutes.
Conclusions: Capillary zone electrophoresis using an acidic background electrolyte proved to be an efficient tool in the separation of fluoroquinolones from different generations. Also the proposed methods are particular environment-friendly replacement and improvement of a common high performance liquid chromatography determination with rapid analysis time without using any organic solvents.

Published: July 2014

Abstract
Introduction: One of the most common pathologies in urological praxis is urinary lithiasis. Extracorporeal shock wave lithotripsy (ESWL) or frequently retrograde ureteroscopy are modern pathways in the treatment of this kind of pathology. There are certain problems which may develop after the ureteroscopy such as infection with fever complication.
Material and method: This retrospective study evaluates 164 patients who underwent ureteroscopy treatment over a period of two years (2011-2012). We compared the infection complication episode (with fever) in 33 (20.12%) patients with antibiotic prophylaxis (group A) versus 131 (79.87%) patients without prophylaxis (group B). Antibiotics used for prophylaxis were: amoxicilinum and clavulanic acid, generation I and II cephalosporines.
Results: Twenty-four (14.63%) patients presented postsurgical fever. Most febrile patients were those with grade II hydronephrosis - 16 (66.66%), of which 2 (6.06%) patients from group A and 14 (10.68%) from group B. From group A, 3 (12%) patients with stones below 10 mm had fever, while 18 (14.87%) from group B developed this complication. Among the patients with stones’ size over 10 mm, 1 (14.28) patient from group A and 2 (25%) patients from group B had fever.
Conclusions: Patients undergoing the ureteroscopy treatment should be investigated before the procedures for the presence of bacteria in order to avoid complications like infection associated with fever. Antibiotic prophylaxis may reduce the incidence of postoperative infection in the ureteroscopy treatment.

Published: July 2014

Abstract
Background: Incisional hernias are important complications of abdominal surgery. Normally they are followed by the growth of the hernia sac and an increase of the abdominal wall defect with loss of domain of the herniated organs.
Case report: We report a case of a 51 year old female, admitted in the 1st Surgical Clinic of the County Emergency Clinical Hospital of Tîrgu Mureș with a large median reducible incisional hernia and a wall defect of 10/12 cm. The abdominoplasty was performed using the Oscar Ramirez technique, which consists of a longitudinal incision along the aponeurosis of the external oblique muscle, at approximately 1-2 cm from the external edge of the rectus abdominis. This procedure allows the abdominal wall closure. This case is part of a lot of 4 patients who received this treatment using the aforementioned procedure in the past 2 months. Postoperative recovery was favorable, bowel movements were present on the second day after the surgery, the subcutaneous drains were shortened on the fifth day and removed on the sixth. There were no immediate postoperative complications or up to a month after the surgery. The patient was discharged on the seventh day.
Conclusions: This technique can be used alone in case of large abdominal wall defects, or prequeling an on-lay mesh procedure addressed to a weak abdominal wall, case in which the functional result is superior to a substitutional mesh.
Anatomical and Surgical Basis for Adult Living Donor Liver Transplantation with the Right Liver Lobe

Published: July 2014

Abstract
Liver transplantation is now a standard procedure for the treatment of end stage liver diseases. Since 1968 until 2012, a number of 113,627 liver transplantations were performed in Europe, in 28 countries and 153 institutions. Despite these impressive figures the waiting list is growing every year. Transplant surgeons were preoccupied to find new ways to increase the donor pool. Among them: reduced size liver transplantation, split liver technique and more recently living donor liver transplantation. At first in the early `90, living donor liver transplantation was used for pediatric patients because the left lateral hepatic segments were harvested. This graft is too small for the metabolic demands of an adult patient. So the next step was the harvesting of the right liver lobe from the donor and transplantation to adult patients. Living donor liver transplantation has gained fast a wide acceptance but there are a few issues to discuss. The main concern is about the donor safety which is a healthy person undergoing major surgery with potential risks. Also the surgical technique evolved due to a better understanding of the anatomy and physiology of the liver and the right liver graft. We discuss here the anatomical and surgical basis for living donor liver transplantation with the right liver lobe.
Response of Hybrid Cymbidium (Orchidaceae) Protocorm-Like Bodies to 26 Plant Growth Regulators

Abstract
Teixeira da Silva J.A., 2014: Response of hybrid Cymbidium (Orchidaceae) protocorm-like bodies to 26 plant growth regulators [Cymbidium (Orchidaceae) hibrido į protokormą panašių kūnelių reakcija į 26 augalų augimo reguliatorius]. - Bot. Lith., 20(1): 3-13.
Plant growth regulators (PGRs) are one of the most effective means of controlling plant organogenesis in vitro. Hybrid orchid production relies on effective protocols to maximize clonal shoot output. This is best achieved when protocormlike bodies (PLBs) are propagated. In a bid to deepen orchidologists’ understanding of basic responses of Cymbidium to PGRs, this study aimed to establish the organogenic response of hybrid Cymbidium Twilight Moon ‘Day Light’ half-PLBs or PLB thin cell layers (TCLs) to a single application of PGRs (6 auxins; 7 cytokinins; 3 alternative PGRs), 3 herbicides or 7 growth inhibitors/retardants at 4 concentrations (1, 2, 4 or 8 mg·1-1) as well as a control (0 mg·1-1), both in the light and in the dark. The control (PGR-containing TC medium) performed best, but all auxins and growth inhibitors and retardants were toxic to neo-PLB formation, resulting in 100% death. A synthetic auxin (BSAA), a cytokinin (4-CPPU) and two herbicides (dicamba and picloram) were equally toxic. No auxins, TIBA, GA3 or SA induced any organogenic response. 1 or 2 mg·1-1 2,4-D or 1 mg·1-1 TDZ induced embryogenic callus, but 2-8 mg·1-1 2,4-D resulted in abnormal shoots. TDZ induced direct multiple shoots. Only five remaining cytokinins (Ads, BA, Kin, ZR, 2iP) could form neo-PLBs, but always significantly less than the controls, independent of the explant used (half- PLBs or tTCLs) and light conditions (light vs darkness). These five cytokinins could be useful for neo-PLB induction of other Cymbidium hybrids. A new concept, the average cumulative value or ACV, is introduced

Authors: Arjhangmehr Afshin , Mohammadzadeh Mohammad , Hossein Feghhi Seyed Amir , Hassanpour Saeed Tasouji 
Published: July 2014

Abstract
An industrial gauge for measuring thickness of a gold coating layer deposited on a steel base through detection of the backscattered beta particles has been described. 3H, 14C and 63Ni pure beta emitters have been tested as the radioisotopic sources of the system individually in a fixed geometry. Analytical calculations have been performed in each case. Furthermore, simulations based on Monte Carlo stochastic technique (MCNP) have been processed. The obtained results from both methods have been compared to define the sensitivity of the system in each case. Finally for the first time, fuzzy TOPSIS method has been used for choosing the best source in the defined geometry for manufacturing, considering the following three criteria: (a) saturation thickness, (b) precision and (c) sensitivity. Results have shown that 3H source is the best alternative to the introduced measuring system.

Published: July 2014

Abstract
The European Bee-eater (Merops apiaster Linnaeus, 1758) is known as ‛beekeeper bird’ and an effective ecosystem engineer species. The fact that in 2013 it became ‛The Bird of the Year’ in Hungary offers the possibility to summarise the information about the distribution, population size, breeding and feeding ecology, dispersion, migration, intra- and interspecific relationships as well as the nature conservation status of the bee-eater population breeding in Hungary. Though this review focuses on the Hungarian population trends, but also summarises the major research results from other countries. In the period of 1992-2013, the number of breeding pairs were surveyed in 5897 2.5×2.5 km UTM squares in the frame of the Monitoring of Rare and Colonial Breeding Birds programme. In the surveyed area during the period of 1992-2013, the most accurate estimate suggests a 10600-19600 breeding pair population. The larger nesting colonies were observed in the following regions: Zala Hills, Outer Somogy, Gerecse, Velencei Hills, Mezőföld, Gödöllő Hills, Tápió, Bükkalja, Taktaköz, Körös region. The annual population indices showed marked fluctuation with stable long term population trend in Hungary. The national monitoring and protection project of the European Bee-eater revealed the most important factors endangering the nesting populations, these are weed invasion and the collapse of vertical banks, mining carried out in the nesting period and direct human-caused disturbance (e.g. shooting, tourism).
