Telemanagement: Notwendigkeit für ein komplexes Verhaltensrepertoire
Authors: Grote Gudela , Manchen Spörri Sylvia , Springall Lille 
Published: June 2016

Abstract
Anforderungen an die Führung virtueller Teams und die Effekte von Führungs- und Kommunikationsverhalten auf Teamleistung und soziale Prozesse im Team wurden in mündlichen und schriftlichen Befragungen von 29 Führungskräften sowie schriftlicher Befragung ihrer verteilt arbeitenden Teams (N=134) erfasst. Es zeigte sich, dass sowohl moderne Führungskonzepte wie Empowering Leadership als auch traditionelle Ansätze wie die direktive Führung in den mentalen Modellen der Führungskräfte nebeneinander existieren und selten als widersprüchlich erkannt werden. Anliegen vieler Führungskräfte ist es, situationsangemessen auf verschiedene Führungsstile zurückgreifen zu können. Vor allem in stark verteilten Teams scheint dies eine erfölgversprechende Strategie zu sein. Differenzen in der Wahrnehmung sozialer Prozesse zwischen Vorgesetzten und Mitarbeitenden stehen in negativem Zusammenhang zur Leistung, was die Bedeutsamkeit gemeinsamer mentaler Modelle der Team- und Führungssituation aufzeigt. Von den Führungskräften wurde ein breites Spektrum an Medien situations- und aufgabenangemessen eingesetzt. Es fand sich auch ein positiver Zusammenhang zwischen dem Virtualitätsgrad der Teams und der Kommunikationsqualität.
Die Beschäftigung Älterer in Europa zwischen Vorruhestand und „Work-Line“
Authors: Bosch Gerhard , Schief Sebastian 
Published: June 2016

Abstract
Die Europäische Union hat sich hinsichtlich der Beschäftigung Älterer ehrgeizige Ziele gesetzt. Im März 2001 legte der Europäische Rat in Stockholm fest, dass bis 2010 mindestens die Hälfte der EUBevölkerung im Alter von 55 bis 64 Jahren in Beschäftigung sein soll. Der vorliegende Artikel untersucht mit Daten der Europäischen Arbeitskräftestichprobe 2004 die Partizipation am Arbeitsmarkt älterer Beschäftigter. Gegenwärtig erreichen nur 5 der 15 alten EU Länder bereits eine Beschäftigungsquote der 55 bis 64-Jährigen über 50%. Es wird gezeigt, dass Länder, die der Politik der „Work Line“, also der Aktivierung von Personen im Erwerbsalter, folgen (z.B. Dänemark, Schweden), deutlich höhere Beschäftigungsquoten aufweisen als jene, die eine Vorruhestandspolitik (z.B. Deutschland, Frankreich) betrieben haben. Der Vergleich zwischen Work-Line-Ländern und Vorruhestandsländern verweist auf sechs Problembündel, deren Bewältigung zentral für die Erhöhung der Beschäftigungsquote Älterer ist (Gleichstellungsproblem, Humanisierungsproblem, Qualifikationsproblem, Flexibilitätsproblem, Motivationsproblem, Wachstumsproblem). Eine rein altersspezifische Politik wird diese Konflikte nicht auflösen können.

Zwei Methoden zum Entwurf ressourcenschonender funkbasierter digitaler Regelungssysteme
Authors: Haupt Andreas , Steffen Thomas 
Published: June 2016

Zusammenfassung
In funkbasierten Regelungssystemen, in denen sich mehrere Regelkreise ein Netzwerk teilen, sind nicht nur die klassischen
Reglerperformanzkriterien (Regelgüte, Einschwingverhalten) von Interesse, sondern auch die durch das Netzwerkprotokoll
induzierten Effekte (z. B. Verzögerungen, Paketausfälle, Jitter) und Limitierungen der Soft- und Hardware der
Netzwerkknoten (z. B. Rechenleistung, Speicher, Batterieenergie, Sendeleistung). Diese Parameter sind oft voneinander
abhängig, z. B. verbessert eine erhöhte Frequenz von Netzwerktelegrammen i. d. R. die Regelgüte, erhöht jedoch
Energiebedarf und Kommunikationsbandbreite. Am Lehrstuhl für Automatisierungstechnik wurde im Rahmen von zwei
unabhängigen DFG-Projekten untersucht, wie sich Regelungsverfahren effizient in solchen Netzwerkumgebungen entwerfen und
implementieren lassen.

Published: June 2016

Zusammenfassung
Ein Gebäudeautomationssystem (GA-System) ist durch eine Vielzahl von automatisierten Funktionen geprägt. Die Planung und Auslegung
eines GA-Systems ist daher ein aufwändiger und fehlerträchtiger Vorgang. Dabei werden Planungsfehler oft erst bei der Inbetriebnahme
des Gebäudes erkannt. Um eine frühzeitige Funktionsanalyse und Fehlererkennung zu gewährleisten, wurde ein Ansatz für eine effiziente
Erstellung eines funktionalen Modells für die GA entwickelt, mit welchem ein GA-System simuliert, ausgelegt und konfiguriert werden
kann.

Abstract
The aim of this work was to investigate the diversity of diatom assemblages developed in the Przyrwa stream, to assess water quality based on benthic diatoms and to make an attempt at the identification of physicochemical factors having the greatest impact on the differentiation of diatom assemblages. Studies were conducted in 2011-2012 on the Przyrwa stream, a left-side tributary of the Wisłok River flowing through the city of Rzeszów and with its spring section located on the borders of the city. A total of 259 diatom taxa were identified in the Przyrwa stream during three studied seasons. At all investigated sites, the most abundant population consisted of Ulnaria ulna (Nitzsch) Compère, Cocconeis pediculus Ehrenb., Achnanthidium minutissimum (Kütz.) Czarnecki var. minutissimum, Navicula gregaria Donkin, Planothidium frequentissimum (Lange-Bert.) Lange-Bert., P. lanceolatum (Brébisson) Lange-Bert., Navicula lanceolata (C. Agardh) Ehrenb., Amphora pediculus (Kütz.) Grunow, Eolimna minima, (Grunow) Lange-Bert., Melosira varians C. Agardh and Cyclotella meneghiniana Kütz. Based on IPS (Specific Pollution Sensitivity Index) and GDI (Generic Diatom Index) indices, the ecological status of the Przyrwa stream was assessed as moderate to poor (mostly III-IV class of water quality), while the TDI (Trophic Diatom Index) index indicated a poor to bad ecological status (mainly IV-V class of water quality).
Vegetation differentiation and secondary succession on abandoned agricultural large-areas in south-eastern Poland
Authors: Barabasz-Krasny Beata 
Published: June 2016

Abstract
In Poland, the largest stretches of abandoned agricultural areas were formed at the end of the 1980s, along western and eastern borders, among others, in Przemyśl Foothills (Pogórze Przemyskie). Therefore, the research on the diversity of plant communities from abandoned agricultural areas as well as main directions and the rate of succession after the cessation of management was undertaken in the vicinity of twelve municipalities in south-eastern Poland. This research revealed that the dominating direction of changes of the abandoned agricultural area vegetation was vanishing of plant groups with segetal and meadow species and spreading of shrub communities. A general increase in the forestation rate of the researched abandoned agricultural areas from 10-40% of the area in 1970-1971 to about 30-70% in 2003-2004 may be the evidence of the occurrence intensity of those phenomena.

Published: June 2016

AbstractThe field of nanobiocatalysis has experienced a rapid growth due to recent advances in nanotechnology. However, biocatalytic processes are often limited by the lack of stability of the enzymes and their short lifetime. Therefore, immobilization is key to the successful implementation of industrial processes based on enzymes. Immobilization of enzymes on functionalized nanostructured materials could give higher stability to nanobiocatalysts while maintaining free enzyme activity and easy recyclability under various conditions. This review will discuss recent developments in nanobiocatalysis to improve the stability of the enzyme using various nanostructured materials such as mesoporous materials, nanofibers, nanoparticles, nanotubes, and individual nanoparticles enzymes. Also, this review summarizes the recent evolution of nanostructured biocatalysts with an emphasis on those formed with polymers. Based on the synthetic procedures used, established methods fall into two important categories: “grafting onto” and “grafting from”. The fundamentals of each method in enhancing enzyme stability and the use of these new nanobiocatalysts as tools for different applications in different areas are discussed.

Published: June 2016

AbstractWe associate a semigroup B(S) to every semiring S with semilattice additive reduct, namely the semigroup of all k-bi-ideals of S; and such semirings S have been characterized by this associated semigroup B(S). A semiring S is k-regular if and only if B(S) is a regular semigroup. For the left k-Clifford semirings S, B(S) is a left normal band; and consequently, B(S) is a semilattice if S is a k-Clifford semiring. Also we show that the set B
P-Cyclic C-Contraction Result in Menger Spaces Using a Control Function
Authors: Choudhury B. S. , Bhandari S. K. 
Published: June 2016

AbstractThe intrinsic flexibility of probabilistic metric spaces makes it possible to extend the idea of contraction mapping in several inequivalent ways, one of which being the C-contraction. Cyclic contractions are another type of contractions used extensively in global optimization problems. We introduced here p-cyclic contractions which are probabilistic C-contraction types. It involves p numbers of subsets of the spaces and involves two control functions for its definitions. We show that such contractions have fixed points in a complete probabilistic metric space. The main result is supported with an example and extends several existing results.
Improving diagnosis of pneumococcal disease by multiparameter testing and micro/nanotechnologies
Authors: Salieb-Beugelaar Georgette B. , Zhang Bei , Nigo Maurice M. , Frischmann Sieghard , Hunziker Patrick R. 
Published: June 2016

Abstract
The diagnosis and management of pneumococcal disease remains challenging, in particular in children who often are asymptomatic carriers, and in low-income countries with a high morbidity and mortality from febrile illnesses where the broad range of bacterial, viral and parasitic cases are in contrast to limited, diagnostic resources. Integration of multiple markers into a single, rapid test is desirable in such situations. Likewise, the development of multiparameter tests for relevant arrays of pathogens is important to avoid overtreatment of febrile syndromes with antibiotics. Miniaturization of tests through use of micro- and nanotechnologies combines several advantages: miniaturization reduces sample requirements, reduces the use of consumables and reagents leading to a reduction in costs, facilitates parallelization, enables point-of-care use of diagnostic equipment and even reduces the amount of potentially infectious disposables, characteristics that are highly desirable in most healthcare settings. This critical review emphasizes our vision on the importance of multiparametric testing for diagnosing pneumococcal infections in patients with fever and examines recent relevant developments in micro/nanotechnologies to achieve this goal.

Effect of carbon sources on physicochemical properties of bacterial cellulose produced from Gluconacetobacter xylinus MTCC 7795
Authors: Singh Rushali , Mathur Ashwani , Goswami Navendu , Mathur Garima 
Published: June 2016

Abstract
In this study, the effect of modified Hestrin Schramm (HS) medium supplemented with different carbon sources viz., glucose, fructose, galactose and lactic acid on the yield and physicochemical properties of bacterial cellulose (BC) produced from Gluconacetobacter xylinus strain MTCC 7795 in shake flask culture conditions was investigated. Growth studies indicated that all carbon sources supported the growth of bacteria, though specific growth rate and doubling time differs. Fructose gave the highest cellulose yield of 7.72 mg/ml after 130 h of fermentation, while yield in glucose and galactose supplemented medium were 4.49 mg/ml and 3.38 mg/ml, respectively. X-ray powder diffraction (XRD) analysis revealed that all BC samples were amorphous in comparison to commercial cellulose. Fourier transform infrared (FTIR) spectroscopic investigations of bacterial cellulose (BC) samples affirm the purity of the cellulose produced. No significant variations in physicochemical properties of cellulose samples produced with different carbon sources were observed. This study for the first time has investigated the effect of carbon sources on physicochemical properties of bacterial cellulose produced by G. xylinus MTCC 7795 and provides a strategy for economical production of BC with anticipated application in therapeutics and tissue engineering.
Changes of carbon dioxide concentration in soils caused by forestry machine traffic
Authors: Allman Michal , Jankovský Martin , Messingerová Valéria , Allmanová Zuzana 
Published: June 2016

Abstract
Forestry machine traffic causes a number of changes that are not immediately reflected in morphological changes of surface soil. These changes are physical and chemical in nature. The change in subsurface soil CO2 concentration was one of the parameters of interest. The critical CO2 concentration is thought to fluctuate around 0.6%. The primary objective of this paper was to determine the impact of forestry machine traffic on subsurface soil CO2 concentration. We measured CO2 concentration in the areas undisturbed by machinery and in the ruts in skid trails in eight forest stands. The measurements were performed using a Vaisala MI 70 meter. The results confirmed significant differences in gas concentrations between the individual measurement sites. In the ruts of the skid trails, CO2 concentrations fluctuated in a range of 0.5 to 2.81% and significantly exceeded the critical concentration. Moisture content and bulk density had a significant impact on the change in gas concentration beneath the surface, which was confirmed by multivariate analysis of variance that revealed that the values of the coefficient of correlation fluctuated in a range of 0.39 to 0.74.

There are 15 plant species included in the Russian Red Book, which occur in the Republic of Mordovia: Najas tenuissima, Koeleria sclerophylla, Stipa dasyphylla, S. pennata, S. pulcherrima, S. zalesskii, Fritillaria ruthenica, Iris aphylla, Cypripedium calceolus, Cephalanthera rubra, Epipogium aphyllum, Neottianthe cucullata, Orchis militaris, Neotinea ustulata, Thymus cimicinus. Of these, only C. calceolus is included in the Global Red List as Critically Endangered. Threat status for studied species in Mordovia was assessed, and their distribution dynamics in this region throughout 12 years was described. Recent floristic studies, inspections of herbariums and literature were used for searches all provided data. Grid mapping and IUCN criteria were used. Nine taxa were determined as Critically Endangered, three as Endangered, one as Vulnerable, one as Near Threatened and one as Data Deficient. The areas of occupancy and extent of occurrence in Mordovia were assessed for each taxon. All studied species should be included in the next edition of the Mordovian Red Book. F. ruthenica, E. aphyllum, N. ustulata, T. cimicinus require additional studies to confirm earlier observations.
Railway embankments - a refuge areas for food flora, and pollinators in agricultural landscape
Authors: Wrzesień Małgorzata , Jachuła Jacek , Denisow Bożena 
Published: June 2016

Abstract
In a modern agricultural landscape the assurance of food resources is a key issue in the maintaince and control of food niche for pollinators. In the present study we evaluated bee forage flora composition and diversity within railway embankments located in the agricultural landscape, SE Poland. We also analysed the abundance of pollinators that use food resources along railway embankments and recognized insect visitors preference for selected plant species. Railway embankments represent valuable refuge areas for bee forage flora (307 species, i.e. 76.1% of total flora) and pollinators (in total 4172 insect visits from 9 taxonomic groups). However, the richness and abundance of bee forage flora significantly differed between types of the railway distinguished by traffic volume. The highest diversity of bee forage flora is noted along the railway with intermediate traffic volume. Approx. 25% and 40% less bee forage species was identified along railways with low and high traffic volume. Likewise, bee forage flora differed considerably between microhabitat types, i.e. top vs. slope vs. bottom of the embankment. Providing support (e.g. mowing) seems to be an important management type in order to strengthen the native bee forage flora particularly on railway embankments along low and high traffic volume tracks. Such activity is crucial to counteract the spread of aggressive non-forage species (e.g. Calamagrostis epigejos, Artemisia vulgaris, Phragmites communis) and invasive species (e.g. Bunias orientalis, Solidago gigantea).
GC-MS investigation of the chemical composition of honeybee drone and queen larvae homogenate
Authors: Isidorov Valery A. , Bakier Sławomir , Stocki Marcin 
Published: June 2016

Abstract
Honeybee larva homogenate appears to be underrated and insufficiently explored but this homogenate is an exceptionally valuable honeybee product. Drone larva homogenate is very nutritional due to its high content of proteins, free amino acids, lipids, and carbohydrates. Moreover, the biological characteristics of honeybee larvae indicate the presence of chemical substances that may be pharmacologically active. In spite of the above, the chemical composition of honeybee larva has not gained as much attention as that of other bee products. In this study, the chemical composition of honeybee brood homogenate has been investigated using gas chromatography/mass spectrometry. As a result, it was possible to isolate as many as 115 extractive organic compounds from 6 samples of crude queen and 9 samples of drone homogenate. The main groups of substances extracted from either type of homogenate were composed of free amino acids and carbohydrates. The relative content of amino acids in queen homogenate as well as the share of essential amino acids were found to be higher than in the drone homogenate. Disaccharide trehalose was the dominant sugar in the queen larvae, whilst glucose prevailed in the drone larvae. Comparative chemical analyses of honeybee queen and drone larva homogenates have allowed us to make a preliminary inference about a higher overall value of the former.
Physico-chemical characterization and antibacterial activity of different types of honey tested on strains isolated from hospitalized patients
Authors: Junie Lia M. , Vică Mihaela L. , Glevitzky Mirel , Matei Horea V. 
Published: June 2016

Abstract
The first aim of the study was to compare the antibacterial activity of several types of honey of different origins, against some bacterial resistant strains. The strains had been isolated from patients. The second aim was to discover the correlations between the antibacterial character of honey and the physico-chemical properties of the honey. Ten honey samples (polyfloral, linden, acacia, manna, and sunflower) from the centre of Romania were tested to determine their antibacterial properties against the following bacterial species: Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Salmonella enterica serovar Typhimurium, Bacillus cereus, Bacillus subtilis, and Listeria monocytogenes. Bacterial cultures in nutrient broth and the culture medium Mueller-Hinton agar were used. The susceptibility to antibiotics was performed using the disk diffusion method. All honey samples showed antibacterial activity on the isolated bacterial strains, in particular polyfloral (inhibition zone 13-21 mm in diameter) - because it is the source of several plants, and manna (inhibition zone 13-19.5 mm in diameter), and sunflower (inhibition zone 14-18.5 mm in diameter). Pure honey has a significant antibacterial activity against some bacteria which are resistant to antibiotics. Bacterial strains differed in their sensitivity to honeys. Pseudomonas aeruginosa and Staphylococcus aureus were the most sensitive. The present study revealed that honey antibacterial activity depends on the origin of the honey. We also found that there was a significant correlation between antibacterial activity of honeys and the colour of the honey but not between acidity and pH. The statistical analysis showed that the honey type influences the antibacterial activity (diameter of the bacterial strains inhibition zones).
Critical Congenital Heart Diseases as Life-threatening Conditions in the Emergency Room
Authors: Togănel Rodica 
Published: June 2016

Abstract
Critical congenital heart disease (CHD) represents a special type of cardiovascular emergency due to the complexity of the associated pathology. In many cases, urgent surgery or catheter-based intervention is required as the condition might be life-threatening. In patients with ductal-dependent lesions, closure of the patent ductus arteriosus (PDA) within the first few days postpartum, can cause sudden clinical deterioration with potentially life-threatening consequences. The diagnostic challenges, clinical presentation and particularities related to the closure of PDA in life-threatening critical CHD are presented.
