Published: September 2017

AbstractThe main objective of this paper is to make an analysis of the relationships between three fundamental constructs in every tourist destination - the perceived value of the attributes of destination, satisfaction and loyalty. Taking into account the perceived value of the tourists who visit this country, three types of visitors have been identified that are considered valid and useful for segmenting the Dominican Republic as a tourist destination: a high perception tourist, a tourist average and a low perception tourist. The attributes valued by the tourists reveal that the perceptive dimension relates to the tourism services and infrastructures of a destination discriminate in a significant way in the degree of satisfaction and attitudinal loyalty declared by the visitors. The conclusions show the need to consider the perceived value of the satisfied and loyal tourist as an essential tool for the Dominican Republic to continue to grow as a tourist destination.
The Effect of Social Media on Identity Construction
Authors: Gündüz Uğur 
Published: September 2017

AbstractThe social media platforms have a growing importance in our lives since they are the places where we “showcase” our living experiences. They also reflect a variety of dimensions regarding our position in the virtual and physical social life. Both of these factors make people to play certain characters in the social arena. The Social Network is gaining more and more importance in today’s world and has a deeper impact on the society as to the traditional media. Social media enables identity expression, exploration, and experimentation; something natural for the human experience. It is the agencies in real life, which provide a source of names for different sectors, that inspire the internet communities and the interactions they make within themselves. It is essential to comprehend the motives of agencies to have an understanding of the group interactions on social platforms. The enable individuals present themselves to others and determine the way they would like to be perceives in addition to helping them connect and interact with people, and participate in the activities they wish. Communicating online offers many ways to connect with others: individuals may or may not use their real names, and they can open as many accounts as they want to. This study explores practical aspects of identity construction, relating to issues virtual communities and social media. It also analyzes the probable reasons that individuals feel the need to create a virtual identity for themselves as well as “the spiral of transformation”, that is, the creation period goes ahead of the internet to reach the real life. This study also aims at concentrating on the virtual communities appearing in the social networks while questioning their social and cultural qualities and values.

AbstractThe study investigated the availability and utilization of ICT resources in the teaching of Computer Education among Secondary School Teachers in Anambra State. Two research questions guided the study. The population consisted of 450 computer teachers teaching computer education in the schools. From the population, 300 computer teachers were sampled and used for the study. The instrument for data collection was a self-developed 40 – item questionnaire. It was validated by experts and the reliability co-efficient stood at 0.79. The data collected were analysed using frequencies and percentages. The findings revealed that many of the ICT resources needed for the teaching of computer education are not available. It was also revealed that majority of the resources needed for the teaching of computer education are not being used by the teachers. In view of the findings, recommendations were made.
A Critique of John Hick’s Multiple Incarnation: Theology and Christian Approach to Religious Dialogue
Authors: Okwuosa Lawrence Nwachukwu , Nwaoga Chinyere Theresa , Uroko Favour C. 
Published: September 2017

Abstract
The question of Christ’s divine nature is one issue that has caused ripples among the religions of the world. While it is the ground of Christian beliefs and explained as the doctrine of the divine incarnation of God’s only Son into the world, for some people it is faith taken too far. As intellectual ink is being spilt on Christ’s divine incarnation, John Hick, a theologian of great repute, argues of a multiple metaphorical incarnations that include Jesus Christ and other prophetic voices in the religious circle. This has heightened the question and the need to investigate this theological issue. Hence, this paper aims at not only denying the possibility of multiple incarnations, which would distort the entire Christian teaching but also demonstrates how Christ’s incarnation is a witnessed non-metaphoric belief. For this purpose, the paper adopts descriptive phenomenology in its methodology.

Published: September 2017

Abstract
Two fungal strains, isolated from Livingston Island, Antarctica (Penicillium commune 161, psychrotolerant and Aspergillus glaucus 363, mesophilic) were investigated for a relationship between growth temperature and oxidative stress response. Cultivation at temperatures below – (10 and 15°C and 10 and 20°C for P. commune and A. glaucus, respectively) and above (25°C and 30°C for P. commune and A. glaucus, respectively) the optimum caused significant difference in growth and glucose uptake in comparison with the control cultures. Enhanced level of reserve carbohydrates (glycogen and trehalose) was determined under cultivation at different temperatures from the optimal one. While the highest content of trehalose was found in the exponential phase, glycogen accumulation was observed in the stationary phase when growth conditions deteriorate. The growth at temperature below– and above–optimum caused strain–dependent changes in two antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT). While SOD activity in the psychrotolerant strain increases with decreasing of growth temperature, the mesophilic A. glaucus demonstrated marked reduction of it at below– and above–optimal temperature. Decreasing trend of CAT activity was observed in both strains below the optimal temperature indicating a lack of antioxidant protection from this enzyme under the cold stress conditions.

Published: September 2017

AbstractThe specific activity of natural gamma emitters like actinium (228Ac), bismuth (212Bi,214Bi), lead (212Pb,214Pb), potassium (40K), radium (224Ra), thallium (208Tl) and artificial radioisotope caesium (137Cs) was measured in 2005 in the surface layer of marine sediments in the northern Svalbard: Wijdefjorden, Woodfjorden, Vestfjorden and Bockfjorden as well as in the freshwater reservoirs in Andre Land. Nonuniform spatial distribution of these radionuclides was found. Sediment sample from Bockfjorden had the highest specific activities of all natural radionuclides. The specific radioactivity of137Cs was much lower than specific radioactivities of natural radionuclides but there were differences between investigated locations. The distribution of137Cs is similar to persistent organic pollutants of the lake sediments in the area.

Authors: Abakumov Evgeny , Shamilishviliy Georgy , Yurtaev Andrey 
Published: September 2017

AbstractBackground concentrations of main trace elements and polycyclic aromatic hydrocarbons (PAHs) were investigated in pristine soils of the Beliy Island situated in the Kara Sea, Yamal autonomous region, North-West Siberia, Russia. Belyi Island is considered as reference landscpae for further investigation of soil polychemical contamination of the Yamal region. Three plots with different functional load (mature ecosystem, occasionally and permanently affected plots) were investigated with aim to evaluate the trend of long term polychemical effect on Stagnic Cryosols – benchmark soil type of the Yamal region. Accumulation of trace elements was not fixed in all soils investigated due to absence of direct sources of heavy metals on the territory of the Beliy Island. At the same time, there were essential alterations of PAHs fractional composition and content due to pronounced accumulation of the petroleum products combustion in the vicinity of the permanent meteorological station and former seasonal field base. The most intensive and statistically significant accumulation was noted for phenanthrene, anthracene, benzo[k]fluoranthene and benzo[a]pyrene. This indicates accumulation of the PAHs in soils, affected by the anthropogenic activity on the meteorological station. The most pronounced differences were revealed for the superficial layer of 0–5 cm. Deeper horizons of soil did not show accumulation of contaminants. Data obtained can be used for organization of further monitoring of contamination of soils and landscapes in Yamal as developing and industrial region.

Study of Wastewaters Contaminated with Heavy Metals in Bioethanol Production
Authors: Bartošová Alica , Blinová Lenka 
Published: September 2017

AbstractBioethanol as a substitute for traditional sources of energy, especially oil transport, is currently one of the most researched alternative motor fuels. Normally, bioethanol is produced from agricultural crops such as sugar cane or corn. However, this is counter-productive, because agriculture is primarily serving to ensure enough food for the people. It is therefore necessary to look for new production of appropriate non-food crops or find an added value to this process. Utilisation of contaminated water from metal industry could be one of them. Based on the hypothesis of reduction of some toxic metals with higher oxidation number is opening the possibility of using this wastewater in alcohol fermentation of any kind of biomass. In this study, hexavalent chromium Cr(VI) was used as a model contaminant in the process of aerobic fermentation of corn to bioethanol. To determine the reduction potential of glucose to Cr(VI), and to quantitatively determinate the glucose content after saccharification, UV/VIS spectrophotometry was used. As a method of qualitative determination of fermentation product, gas chromatography with mass detection was used. Infrared spectrometry was used for qualitative analyses of produced ethanol. Based on the established results shown in this paper, we can conclude that the presence of hexavalent chromium in the fermentation process does not have a significant negative impact, while offering the opportunity of using the industrial wastewaters for the production of bioethanol fuel.

Plotting the Flight Envelope of an Unmanned Aircraft System Air Vehicle
Authors: Glīzde Nikolajs 
Published: September 2017

Abstract
The research is focused on the development of an Unmanned Aircraft System. One of the design process steps in the preliminary design phase is the calculation of the flight envelope for the Unmanned Aircraft System air vehicle. The results obtained will be used in the further design process. A flight envelope determines the minimum requirements for the object in Certification Specifications. The present situation does not impose any Certification Specification requirements for the class of the Unmanned Aircraft System under the development of the general European Union trend defined in the road map for the implementation of the Unmanned Aircraft System. However, operation in common European Aerospace imposes the necessity for regulations for micro class systems as well.

Authors: Parnreiter Christof 
Published: September 2017

ZusammenfassungDas Ziel dieses Textes ist es, die in der Global City Forschung bislang wenig untersuchten Steuerungsfunktionen von unternehmensorientierten Dienstleistungsfirmen in den Mittelpunkt zu rücken. Dazu werden Global Cities als Governance-Knoten von Wertschöpfungsketten konzeptualisiert. Auf der empirischen Ebene wird am Beispiel der klassischen Megacity Mexico City argumentiert, dass auch Städte des „Globalen Südens“ als solche Orte weltwirtschaftlicher Steuerung fungieren.
Transformatives Wirtschaften in der urbanen Ernährungsbewegung: zwei Fallbeispiele aus Leipzig und München
Authors: Kropp Cordula , Müller Christa 
Published: September 2017

ZusammenfassungDer Beitrag diskutiert die neuen urbanen Ernährungsbewegungen und ihre räumlichen Wirkungen, ästhetischen Inszenierungen und wirtschaftlichen Konzepte. Auf der Basis qualitativer Einzelfallstudien in Deutschland wird gezeigt, wie die ‚Wiedereinbettung’ von Ernährungsarrangements in lebensweltliche und regionalökonomische Kontexte praktisch erprobt wird. Dafür schlagen wir ein Verständnis von „transformativem Wirtschaften“ vor und beleuchten, inwiefern transformative Vorstellungen von Urbanität, Wohlstand und kollektivem Handeln entstehen. Im Vergleich zu älteren öko-sozialen Bewegungen zeigt sich, dass die neuen Akteure immer zugleich auf mehreren Ebenen agieren und dadurch die Komplexitätsanforderungen von sozialem Wandel mit Bezug zu globalen Diskurs- und Problemzusammenhängen aufgreifen.
Anthocyanin Formation in the Petals of Hibiscus mutabilis L
Authors: Amrhein Nikolaus , Frank Gert 
Published: September 2017

Abstract
When opening in the morning flowers of Hibiscus mutabilis L. appear white or ivory. The flower colour changes to red by late afternoon due to the accumulation of the anthocyanin cyanidin-3-sambubioside. At the onset, and during the rapid phase of pigment accumulation, phenylalanine ammonia-lyase (PAL) activity in the petals increases rapidly to seven times its initial level and then decreases while the flower senesces. In excised petals, the PAL inhibitor L-α-aminooxy-β-phenylpropionic acid (AOPP) suppresses pigment formation and causes the accumu­lation of phenylalanine. Anthocyanin synthesis depends, therefore, on the de novo production of cinnamic acid.
Carbon Isotope Fractionation by Autotrophic Bacteria with Three Different C02 Fixation Pathways
Authors: Preuß Andrea , Schauder Rolf , Fuchs Georg , Stichler Willibald 
Published: September 2017

Abstract
Carbon isotope fractionation during autotrophic growth o f different bacteria which possess different autotrophic CO2 fixation pathways has been studied. 13C /12C -Ratios in the cell carbon of the following bacteria were determined (CO2 fixation pathway suggested or proven in paren­theses): Alkaligenes eutrophus (reductive pentose phosphate cycle), Desulfobacterium autotrophicum and Acetobacterium woodii (reductive acetyl-CoA pathway), Desulfobacter hydrogenophilus and Thermoproteus neutrophilus (reductive citric acid cycle). The Δδ13C values, which indicate the per mille deviation of the 13C content of cell carbon from that of the CO : used as the sole carbon source, range from - 10%° (reductive citric acid cycle) over - 26%° (reductive pentose phosphate cycle) to -36%° (reductive acetyl-CoA pathway). Acetate formed via the acetyl-CoA pathway by the acetogenic Acetobacterium woodii showed a Δδ13C = -40%°. These data are discussed in view of the different CO2 fixation reactions used by the bacteria and especially with regard to the isotopic composition of sedimentary carbon through time.
Relationship between Molecular Properties of some Photosystem II Inhibitors and their Activity on Triazine-Resistant and -Susceptible Chloroplasts
Authors: Creuzet S. , Gilquin B. , Ducruet J. M. 
Published: September 2017

Abstract
The conformations and electronic properties of several urea/amide, uracil, s-triazine and methylthiopyrimidine inhibitors of photosystem II were determined using molecular mechanics (CHARMM , SYBYL) or quantum semi-empirical (MNDO , AM1) methods. Spectroscopic measurements of the in vitro hydrogen bonding capacity of these com pounds were also carried out. The validity of the calculated values was estimated from experimental measurements. The conformational and electronic properties of the inhibitors studied are then discussed in terms of their mechanism of action on the D1 site and its modification by triazine resistance.
Sulfate Transport in Normal and S-Deprived Chlorella fusca
Authors: Biedlingmaier Susanne , Schmidt Ahlert 
Published: September 2017

Abstract
Sulfate uptake into the unicellular green alga Chlorella fusca Shihira et Krauss strain 211-8 b was described as a pH-, temperature-and energy-dependent process. Transport followed triphasic kinetics with Km-values of 1.3 x 10-5, 3.9 x 10-5 and 2.8 x 10-4
M. The Hill plot showed coeffi­cients of 1.0 for each uptake isotherm. Sulfate uptake was substantially inhibited by chromate, selenate, sulfite, thiosulfate and tetrathionate. Cysteine and other mercaptides diminished sulfate transport, whereas methionine was not inhibitory. Uptake was sensitive towards inhibitors of photosynthesis and respiration and towards SH-group reagents. Sulfate uptake could be strongly enhanced by polyvalent cations, apparently via reduction of the surface potential. Sulfate uptake in S-deprived algae was markedly different from constitutive sulfate uptake. Time kinetics was not linear but showed an initial rapid phase. Uptake was neither multiphasic nor conformed to simple Michaelis-Menten kinetics. Sulfate uptake was hardly affected by pH and temperature in the suboptimal range. The Arrhenius plot was biphasic with a discontinuity at 38 °C.
