Published: August 2017

AbstractA relatively novel approach for easy and quick determination of rutin in buckwheat grain is suggested. The rutin content of the grain in seven common buckwheat (Fagopyrum esculentum) and six Tartary buckwheat (Fagopyrum tataricum) varieties was investigated by means of UV photoacoustic spectroscopy and HPLC as reference method. The lowest content was found in ‘Botan’ and ‘Bamby’ varieties, while the highest values were obtained in the variety ‘Emka’. Rutin content in grain of all Tartary buckwheat varieties was two orders of magnitude higher than in the other varieties. Rutin content in F. esculentum ranges between 9 and 36 mg/100 g dry weight as compared to 921 to 2 132 mg/100 g dry weight in F. tataricum. The UV photoacoustic spectroscopy data show rather good correlations of R2=0.977 and R2=0.980 with values obtained by HPLC data for all measured samples. Therefore, UV photoacoustic spectroscopy can be a cheap and quick method for determining rutin content in buckwheat grain.
Water bird fauna in the Carpathian Basin from the beginnings through historical times
Authors: Kessler Jenő (Eugen) 
Published: August 2017

AbstractThis study aims to summarize the knowledge about the evolution and fossil remains of avian fauna near waterbodies, since ornithologists, who rarely come across or research the paleontology of birds, do not possess significantly detailed knowledge about the evolution and evidence of the current avian fauna.
Timing of Song Thrush Turdus philomelos on pre-nuptial migration in southern Italy
Authors: Scebba Sergio , Castillo Maria Oliveri Del 
Published: August 2017

Abstract
We studied the presence and movements of Song Thrush along the southern Tyrrhenian coast line in the region of Campania, from 2013 to 2016, in order to establish the timing of northward migration. We captured and ringed 150 birds with standardised mist-netting. There was little evidence of migration from the second 10-day period of January, when the trapping began, until the first 10-day period of February. There were no peaks due to the arrival of migrant birds though an increase in captures was recorded during the second 10-day period of February with a very considerable peak during the second 10-day period of March. The mean body mass showed significant increases from the third 10-day period of February, with the highest values recorded in March, also reflected in the accumulation of subcutaneous fat; 91% of subjects with fat scores 3 and 4 were concentrated between the third 10-day period of February and the third 10-day period of March, while the first birds with fat appeared only in the first 10-day period of February. Analysis of several recoveries of thrushes ringed in Campania, in other Italian regions and in other countries, confirms the presence of these birds in Campania in the period between the third 10-day period of January and the third 10-day period of March. The data gathered during the four years of this investigation provide a fairly clear, though not conclusive, picture of the temporal trend of pre-nuptial migration of Song Thrush, which never began before the second 10-day period of February, although it is possible that some birds on migration may be present in the previous 10-day period.

Published: August 2017

AbstractOrnithological studies often rely on long-term bird ringing data sets as sources of information. However, basic descriptive statistics of raw data are rarely provided. In order to fill this gap, here we present the fourth item of a series of exploratory analyses of migration timing and body size measurements of the most frequent Passerine species at a ringing station located in Central Hungary (1984-2016). First, we give a concise description of foreign ring recoveries of the Common Blackbird in relation to Hungary. We then shift focus to data of 6849 ringed individuals and 6081 recaptures derived from the ringing station, where birds have been trapped, handled and ringed with standardized methodology since 1984. Timing is described through annual and daily capture and recapture frequencies and their descriptive statistics. We show annual mean arrival dates within the study period and present the cumulative distributions of first captures with stopover durations. We present the distributions of wing, third primary, tail length and body mass, and the annual means of these variables. Furthermore, we show the distributions of individual fat and muscle scores, and the distributions of body mass within each fat score category. We distinguish the spring and autumn migratory periods, breeding and wintering seasons, ages (i.e. juveniles and adults) and the two sexes. Our aim is to provide a comprehensive overview of the analysed variables. However, we do not aim to interpret the obtained results, merely to draw attention to interesting patterns that may be worth exploring in detail. Data used here are available upon request for further analyses.

Published: August 2017

Abstract
The basis for the quality control of commodity dimension stone blocks for mining industry is the study of fracturing. The identification of fracturing in rock masses is one of the most important aspects in rock mass modelling. Traditional methods for determination properties of fracturing are difficult and hazardous. This paper describes a new approach of fracturing identification, based on image and range data, which realized by image processing and special software. In this article describes a method using new computer algorithms that allow for automated identification and calculation of fracturing parameters. Different digital filters for image processing and mathematical dependences are analyzed. The digital imaging technique has the potential for being used in real time applications. The purpose of this paper is the accurate and fast mapping of fracturing in some walls of the Bukinsky gabbro deposit.

Published: August 2017

AbstractThe main purpose of this work is to confirm the possibility of making largescale orthophotomaps applying unmanned aerial vehicle (UAV) Trimble- UX5. A planned altitude reference of the studying territory was carried out before to the aerial surveying. The studying territory has been marked with distinctive checkpoints in the form of triangles (0.5 × 0.5 × 0.2 m). The checkpoints used to precise the accuracy of orthophotomap have been marked with similar triangles. To determine marked reference point coordinates and check-points method of GNSS in real-time kinematics (RTK) measuring has been applied. Projecting of aerial surveying has been done with the help of installed Trimble Access Aerial Imaging, having been used to run out the UX5. Aerial survey out of the Trimble UX5 UAV has been done with the help of the digital camera SONY NEX-5R from 200m and 300 m altitude. These aerial surveying data have been calculated applying special photogrammetric software Pix 4D. The orthophotomap of the surveying objects has been made with its help. To determine the precise accuracy of the got results of aerial surveying the checkpoint coordinates according to the orthophotomap have been set. The average square error has been calculated according to the set coordinates applying GNSS measurements. A-priori accuracy estimation of spatial coordinates of the studying territory using the aerial surveying data have been calculated: mx=0.11 m, my=0.15 m, mz=0.23 m in the village of Remeniv and mx=0.26 m, my=0.38 m, mz=0.43 m in the town of Vynnyky. The accuracy of determining checkpoint coordinates has been investigated using images obtained out of UAV and the average square error of the reference points. Based on comparative analysis of the got results of the accuracy estimation of the made orthophotomap it can be concluded that the value the average square error does not exceed a-priori accuracy estimation. The possibility of applying Trimble UX5 UAV for making large-scale orthophotomaps has been investigated. The aerial surveying output data using UAV can be applied for monitoring potentially dangerous for people objects, the state border controlling, checking out the plots of settlements. Thus, it is important to control the accuracy the got results. Having based on the done analysis and experimental researches it can be concluded that applying UAV gives the possibility to find data more efficiently in comparison with the land surveying methods. As the result, the Trimble UX5 UAV gives the possibility to survey built-up territories with the required accuracy for making orthophotomaps with the following scales 1: 2000, 1: 1000, 1: 500.

Difficulties in the surgical management of head and neck cancer patient
Authors: Sarafoleanu Codrut , Vuzitas Alexis , Manea Claudiu 
Published: August 2017

AbstractMalignancies of the upper aerodigestive tract are high morbidity bearing and life-threatening diseases, which require thorough care from diagnostic suspicion and confirmation to surgical and/or oncologic treatment and rehabilitation. Difficulties in managing head and neck cancers arise from delays in diagnosis and treatment caused by either patient-related factors or healthcare system-related factors. Tumor origin and stage determine whether surgical excision is feasible, the approach required for safe excision, the extent of functional and aesthetic sacrifice required to attain oncologic safety and the need for reconstructive surgery. A thorough and systematic preoperative risk versus benefits assessment to select potential surgical candidates and give realistic outcomes is important from both a medical and a legal point of view. Because tumors in the head and neck region frequently involve more than one system and sensory organ, potential loss of function from either the disease course, surgical or nonsurgical treatment should be taken into account form a quality of life perspective. Effective management of head and neck cancer patients requires the cooperation and combined effort of a multidisciplinary team of surgeons, physicians and other workers over a long period of time which, in the absence of a specialised head and neck cancer centre and guidelines, can lead to increased morbidity and mortality, and patient dissatisfaction.

Published: August 2017

Abstract
Background: Gaucher disease (GD) is caused by a recessively inherited deficiency of glucocerebrosidase which is encoded by the GBA gene in which nearly 450 mutations have been described. However, only a few genotype- phenotype correlations have been clearly established. The aim of this study was to investigate molecular features of GD in Romanian patients and to evaluate their impact on treatment response. Material and methods: 69 patients, diagnosed between 1997 and 2014 at our national referral laboratory, were included in this study. Frequent point mutations (N370S, L444P, 84GG, R463C) were detected by amplification and restriction enzyme digestion. Recombinant alleles (recTL, recNciI, recA456P) were screened by DNA sequencing. Plasma chitotriosidase served as a biomarker of disease severity throughout the follow-up period. Results: 66 patients had the non-neuronopathic (type 1) form of GD and 3 had the chronic neuronopathic (type 3) phenotype. We identified 79% of the mutant alleles, among which the most frequent mutations were N370S (54%) and L444P (18%). We found a statistically significant (p<0.001) and moderate to good correlation between the total therapeutic dose and the residual chitotriosidase activity (R = 0.621). After two years of treatment, we noticed statistically significant variations in chitotriosidase activity corresponding to the most frequent genotypes (N370S/ unknown allele, N370S/L444P, N370S/N370S and N370S/R463Q). Conclusions: Allele distribution displayed specific features in Romanian GD patients, such as the high prevalence of the N370S allele. Chitotriosidase activity measurement allowed the investigation of genotype influence on treatment outcome.

Published: August 2017

AbstractObjectives: Obesity is associated with oxidative stress due to the overproduction of free radicals in some accompanying states, such as hyperglycemia, elevated lipid levels and chronic inflammation. Free radical accumulation may modify the structure of human serum albumin, generating ischemia-modified albumin (IMA), and increased serum levels of IMA have been linked to obesity-related diseases and oxidative damage. The association of IMA levels with oxidative stress and insulin resistance (IR) has not been evaluated in the context of obesity. The aim of this study is to determine IMA levels in the context of obesity and their relationship with oxidative status and insulin resistance. Methods: Sixty-one adult obese cases with body mass index (BMI) ≥ 30 were evaluated, with 30 healthy adults with 18.5 ≤ BMI ≤ 24.9 included in the control group. IMA, total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), total cholesterol, triglycerides, HDL and LDL-cholesterols were determined. Results: IMA, TAS, TOS, OSI, total cholesterol and LDL-cholesterol levels were not different between the control and obese groups (P-value >0.05), while triglyceride levels were determined to be higher and HDL-cholesterol levels were determined to be lower in the obese group (P-value <0.05). When IMA, TAS, TOS, OSI levels were compared between the control/IR(-), obese/IR(+) and obese/IR(-) groups, no statistically significant differences were detected (P-value >0.05), but the fasting blood glucose level was determined to be higher in the obese/IR(+) group than in the control group. Conclusions: We concluded that obesity and insulin resistance had no effect on IMA levels in the obese group, who showed no impairment in their oxidative balance
OCA Indexes and Convergence Process in Europe
Authors: Frydrych Jakub , Burian Stanislav 
Published: August 2017

Abstract
This paper evaluates the European monetary convergence for period 2001 and 2013. The main purpose of this contribution is the estimation of the so-called OCA index, which indicates the proximity of two economic areas. The paper is theoretically based mainly on the research of Bayoumi and Eichengreen (1997), and Horváth and Komárek (2003). Selection and calculation of variables precedes the econometric analysis, and those variables correspond to the basic characteristics of an optimum currency area. Although the estimated model fulfills the conditions of economic and econometric verifications, its explanatory capabilities are significantly reduced due to the limited set of input data. Results of the analysis point to relatively stable values of indices in the period, but their further examination of the development in time reveals a steady deterioration in the case of almost all economies. That means that the convergence process was not proven because a decrease in OCA indexes values over the time was not observed. According to the results of comparison, methodological approach of the OCA indexes cannot be considered reliable because minor differences in calculation give different outputs.

Published: August 2017

Abstract
Telework has become a natural part of regular work life of employees who use the information communication technology (ICT). Telework has a potential to support postponing retirement for mental workers. The objective of this research was to find out interaction between senior employees′ teleworking and well-being. The main research question was - can telework improve elderly employees′ well-being? Over 100 respondents from different areas in mental work were involved in a quantitative survey. The results of a conducted survey showed that telework is exaggerated to some extent as teleworkers’ well-being (M = 7.79; SD = 1.28) does not diverge from non-teleworkers′ wellbeing (M = 7.75; SD = 1.40). However, telework can be neither underestimated nor taken as interchangeable with traditional work. Therefore, it is necessary to pay attention to telework as a different way of working with its specialties. Systematic approach to telework enables companies to employ elderly by providing diversity of work forms.

Authors: Liesebach H. , Schneck V. 
Published: August 2017

Abstract
Black locust (Robinia pseudoacacia L.), native in mountainous regions in USA, is increasing in importance for forestry in many countries as a „multi-purpose tree“ associated with breeding efforts at the family and clonal levels. A few population genetic studies exist with nuclear, codominantly inherited markers. Here we present an additional marker type, the maternally inherited chloroplast haplotypes. The studied material included samples from the natural range and from artificial stands from three European countries as well as samples from a clone collection. Eleven haplotypes belonging to two clearly separated groups of related haplotypes were found using the PCR-RFLP method. The variation pattern of chloroplast haplotypes in artificial stands is strongly influenced by the local silvicultural management.

Authors: Saklani K. P. , Singh Bhupendra , Bhatt B. P. 
Published: August 2017

Abstract
The present investigation was conducted to record variation of seed and seedling morphological characteristics and germination among eighteen provenances of Quercus leucotrichophora. These traits are important for improving the planting stock material in hand. Significant variations (p<0.05) were recorded for different morphological parameters of seed and seedling among the different provenances. Seed weight was the most variable character among morphological characteristics. Shoot/root ratio and root growth were more variable characters among the seedling traits. Altitude had significant positive relationship with seed weight, seed length and germination per cent. Soil pH was positively correlated with seed weight and germination. These parameters could be used as important criteria for seed source selection. Broad-sense heritability (h2) calculated for different seed and seedling traits showed a considerable portion of genetic variation suggesting the possibility of rapid genetic improvement of these traits. Furthermore, this variability appeared to be geographically structured and would be mainly genetically controlled. Thus the results of present study should be helpful for growing planting material of this potential tree species in afforestation of subtropical to temperate region of Garhwal Himalaya, India.
Diallel Crossing in Pinus cembra: V. Age Trends in Genetic Parameters and Genetic Gain for Height
Authors: Blada I. , Popescu F. 
Published: August 2017

AbstractA full diallel mating design (10 parents) was carried out in a Swiss stone pine panmictic population from the Carpathian Mountains. At age six, after nursery testing, the progenies were field planted to one site, using a completely randomized block design with 100 families, four replicates and a 15 tree row-plot per replication, spaced 2.5 × 2.5 m. Total and annual height of all individuals of this test was assessed at successive ages, between ages eight and 16. In addition, weight of 100 seeds and cotyledon number were considered in correlation analyses. Significant differences occurred in total height for general and specific combining ability effects. Variance components, heritabilities, genetic correlations and genetic gains on growth traits and survival at age 16 were estimated. Across the field testing period, GCA3)variance increased with time, accounting for 65% of plot mean phenotypic variance by age 16. In contrast, SCA variance declined as the progeny test aged accounting for only 9% by age 16. The time trend of the four heritability estimates for total height increased with age across the testing period reaching their highest level between age 14 and 16. Genetic correlations over time for total height rose from 0.85 at age two to 0.94 at age six and then leveled off across the field test indicating that if the goal is to improve 16-year height, early selection can be considered at age six. By selecting the best 10%, 15% and 20% of individuals within the best fullsib families, a genetic gain in total height of 12.4 %, 11.0% and 9.9% respectively, could be achieved at age 16. A higher gain can be obtained if the best general combiner parents are selected and intermated.
High temperature-induced triploid production during embryo sac development in Populus
Authors: Wang J. , Kang X. Y. , Li D. L. 
Published: August 2017

Abstract
Triploid breeding plays an important role in cultivar improvement in the genus Populus L. A novel approach for triploid production with colchicine during embryo sac development was reported recently by Wang et al. (2010). In the present investigation, female catkins of Populus pseudo-simonii × P. nigra ‘Zheyin3#’ during embryo sac development were exposed to high temperature to assess the effectiveness of high temperature for induction of triploid production. In the progeny, 45 triploids were determined by both flow cytometric analysis and somatic chromosome counting. The period 66-72 h after pollination was the most suitable for high temperature-induced triploid production during embryo sac development in the ‘Zheyin3#’. Cytological analysis showed that the frequency of eight-nucleate embryo sacs rose at an increased rate during 66-78 h after pollination, which suggested that the third mitosis during embryo sac development could be the optimal stage for high temperature-induced triploid production. The highest frequency of triploid production was 40%, which was obtained in the 44°C for 2 h treatment 72 h after pollination. In view of both triploid number and production efficiency, treatments with 41°C for 4-6 h or with 44°C for 2 h during 66-72 h after pollination were both effective for triploid induction in ‘Zheyin3#’. Statistical analysis showed that the growth of triploids and diploids was not significantly different. However, highly significant differences were observed for all leaf characteristics. Finally, the significance of high temperature treatment in Populus triploid breeding programs is discussed.
