Published: April 2015

AbstractThe members of the Anopheles maculipennis complex have been incriminated for the transmission of the malaria in Europe, which was endemic until the middle of the century. The global warming and the intensification of the intercontinental travel constitute a risk of the re-emergence of the malaria in Europe, given the presence of the Anopheles vectors. The study has attempted the identification by using the PCR (Polymerase Chain Reaction) of the members of the Anopheles maculipennis complex from the North-eastern area of Romania from the city of Iaşi. In total there have been identified by using the PCR amplifying the ITS2 sequence of the ribosomal DNA, 217 specimens belonging to the complex of A. maculipennis among which: 58 A. atroparvus, 18 A. melanoon, 2 A. labranchiae, 52 A. maculipennis and 87 A. messeae. The ITS2 sequences of the ribosomal DNA have been compared to those of the species belonging to the A. maculipennis available in GenBank. The Species A. labranchiae is reported for the first time in Romania, being identified in the larval stage IV. The adaptation of a new species to the climatic conditions present in the North-eastern Romania, confirms the phenomenon of global warming and also the intensification of the travelling. As a result of the analysis of the A. labranchiae sequence, this one corresponds to the extent of 96% to the species from Italy, registered in GenBank, given the fact that a high number of the inhabitants of the municipality of Iaşi are working in this country.

Published: April 2015

AbstractIn Colombia it is estimated that about 900,000 persons are infected with T. cruzi. There are 25 triatomine species and 5 of them have been reported infected with T. cruzi in the Colombian Caribbean region. In order to obtain more information about the triatomine populations in this region, 89 wild triatomines were collected from four Colombian Departments. The most frequent specie collected was Rhodnius pallescens (65%), followed by Rhodnius prolixus (20%), Panstrongylus geniculatus (10.1%) and Triatoma dimidiata (1%), found in Bolivar, Córdoba, Atlántico/Sucre, and Bolívar Departments, respectively. The majority of triatomines (95.5%) were captured in the arboreal ecotope and 76.4% were found infected with T. cruzi. Interestingly, some of these triatomine species were captured in Departments in which they had not previously been reported and also new finding of triatomine species infected with T. cruzi. These results are relevant, because they can be consequence of a continued geographical expansion of this parasite, not only in the Colombian Caribbean region, but even in all Latin America. The information presented here will contribute in the surveillance and control strategies of the vectors infected with T. cruzi that circulate in four department of Colombian Caribbean region in order to interrupt the transmission to human dwelling.
Chitin, a key factor in immune regulation: lesson from infection with fungi and chitin bearing parasites
Authors: Brodaczewska Klaudia , Donskow-Łysoniewska Katarzyna , Doligalska Maria 
Published: April 2015

AbstractThe probability of infection with fungi, as well as parasitic nematodes or arthropods may increase in overcrowded population of animals and human. The widespread overuse of drugs and immunosuppressants for veterinary or medical treatment create an opportunity for many pathogenic species. The aim of the review is to present the common molecular characteristics of such pathogens as fungi and nematodes and other chitin bearing animals, which may both activate and downregulate the immune response of the host. Although these pathogens are evolutionary distinct and distant, they may provoke similar immune mechanisms. The role of chitin in these phenomena will be reviewed, highlighting the immune reactions that may be induced in mammals by this natural polymer.
Analytical performance specifications for EQA schemes – need for harmonisation
Authors: Dallas Jones Graham Ross 
Published: April 2015

AbstractExternal Quality Assurance (EQA) is a vital tool in laboratory medicine to assess individual laboratory analytical performance and also the differences between the results from different laboratories. This information is also useful for professional bodies and manufacturers as part of post-market surveillance. The process involves the measurement of one or more samples by many laboratories and then assessment of the results. Individual results are generally assessed by how far they lie from a target, which may be established using reference methods or a median of some or all of the submitted results. The distance of a result from the target is compared with analytical performance specifications in order to assess the analytical quality. One of the uses of the Stockholm hierarchy of performance goals is to set the performance specifications for analysis of EQA results. Fifteen years after the Stockholm consensus meeting, EQA analytical performance specifications appear to still vary widely between EQA providers. This can be due to a range of factors, including the rationale for setting the criteria, the expected response to a failure to meet the specified performance, the clinical meaning behind meeting the specifications, and the possible need for further analytical improvements. There are also differences in the models chosen to set the criteria, usually either state of the art or biological variation, and then differences in how these are applied. While harmonisation of EQA performance specifications may be some time off, all EQA providers should define the nature of their specifications and the basis for their selection and make this information available to customers.
Symbolic Representation of Rural Christianity and the Inventiveness of Faith Traditions / 乡村基督教的象征表现与信仰传统的发明性
Authors: Jianbo Huang 
Published: April 2015

Abstract
There are two dominant perceptions on the relationship between Christianity and rural society and culture in China. One is more concerned about the authenticity of Christianity from the church’s perspective, while the other talks about ‘cultural security’ from the view of the local tradition of China. These seemingly contradictory views are in fact based on the same historical model known as impact response. It is a welldeveloped model in that it could explain the “mission church” (church in China), while it seems less or less likely to help us grasp the nature and reality of the “local church” (China’s Church). Hence, this article deals with the following questions, taking Huanan church (South China Church, or SCC) as a case study. Is it plausible for us to consider this kind of local church and its believers as a sort of Christian faith tradition de facto? In light of the assumption, how do we understand the diversified symbolic representations and even inventions? Furthermore, how do we understand the continuity and discontinuity of tradition, if we consider the faith tradition as a cultural tradition?

Selection and design of ionic liquids as solvents in extractive distillation and extraction processes
Authors: Schuur Boelo 
Published: April 2015

AbstractSince the late 1990’s there has been a tremendous growth in literature on ionic liquids (ILs) for a broad range of applications, i.e. catalysis, electrolytes for batteries, in solvolysis of biomass, and also in separation technology. ILs can be applied as solvents for absorption (e.g. of CO2), extractive distillation and extraction processes. That ILs are not magic solvents but have their limitations has also become evident during the past years. Especially the high costs associated with ILs and the lack of experience with these materials in the industrial practice are factors limiting industrial adoption of ILs. The often praised versatility of properties that can be achieved through combination of different cations and anions generates a huge amount of options and makes it difficult to decide where to start when selecting/designing a solvent. This paper focuses on solvent selection/design for applications in extractive distillations and liquid-liquid extractions; also, solvent performance in several specific case studies taken from the open literature is discussed. Important recommendations include: a) make a conceptual process design including the recovery step, regeneration of the IL may be a critical parameter; b) if extractions from aqueous streams are studied, the uptake of water by the IL is an important factor because such co-extracted water is evaporated during the regeneration; c) compare the process with conventional processes to check whether it performs better than the state-of-the-art in industry.

Preparation of quaternary pyridinium salts as possible proton conductors
Authors: Urban Jiří , Havlíček David , Krajbich Josef 
Published: April 2015

AbstractOn basis of earlier experimental experience, the transfer of protons in salts of the organic cation-inorganic anion type occurs primarily through directional arrangement of the anion-anion type short hydrogen bonds. The submitted work presents the preparation of quaternary pyridinium salts of inorganic hydrogen anions in the absence of solvent molecules in their crystal structure. These substances can form only the above-described anion-anion type hydrogen bonds; in addition, the absence of solvate anions increases the stability of the prepared compounds. A total of six substituted pyridinium salts were prepared, four of which have not been described yet: 1,2,4,6-tetraphenylpyridinium perchlorate, 1-benzyl-2,4,6-trimethylpyridinium perchlorate, 1,4-dimethylpyridinium hydrogen sulphate, 1,4-dimethylpyridinium dihydrogen phosphate, 1,4-dimethylpyridinium hydrogen sulphate, and 1,2-dimethyl-5-ethylpyridinium dihydrogen phosphate. Three of these substances were characterised by X-ray structural analysis: 1,2,4,6- tetraphenylpyridinium perchlorate crystallises in the orthorhombic system, space group Pbca; 1- benzyl-2,4,6-trimethylpyridinium perchlorate crystallises in the monoclinic system, space group P2

Published: April 2015

AbstractThis work describes a novel methodology for the recognition of brandies based on direct injection of a raw sample followed by GC-MS analysis. Direct injection was chosen for its simplicity and the fact that the composition of the samples analysed remains unchanged compared to original brandy. The repeatability of the analytical procedure was evaluated by a comparison of the peak areas for randomly selected compounds obtained from 10 parallel measurements. A novel chemometric procedure was investigated in order to separate the samples studied on the basis of their geographical origin, processing technology or maturation time. In this procedure, a principal component analysis was applied to full chromatograms to select the time interval that shows the significant differences between the samples studied. It was shown that the chromatogram recorded at 36-39 min bore the maximal differences, hence it could be used to classify the brandy samples. The chromatographic peaks found within this time interval were identified and their peak areas determined. These compounds could be used as specific markers for determining geographical origin or processing technology.

Published: April 2015

AbstractStylophorum lasiocarpum (Oliv.) Fedde (Papaveraceae) belongs to traditional Chinese medicine herbs but there was minimal information on the content of alkaloids in this plant. Extracts from the aerial part and roots were examined by liquid chromatography with UV and mass spectrometric detection, with nineteen alkaloids identified. Changes in alkaloid content over the entire vegetation period of a one- and two-year old plant were studied. The protoberberine alkaloids, coptisine and stylopine, were found to be the main substances in extracts of the aerial part irrespective of the plant’s age and time of harvest. Variable amounts of protopine, sanguinarine, chelerythrine, chelirubine, macarpine, chelilutine and berberine were also recorded in the aerial part. The roots contained significantly larger quantities of all alkaloids than the aerial part with the levels of most alkaloids varying from May to October, peaking in the middle of the vegetation period. Coptisine was the dominant alkaloid in all samples. The antiproliferative activities of the root extract and of seven individual alkaloids were tested on A375 human malignant melanoma cells. The significant dose-dependent toxicity of the root extract was attributed largely to the quaternary benzo[c]phenanthridine alkaloids, macarpine and sanguinarine.

Published: April 2015

AbstractMethylene blue (MB) removal using eco-friendly, cost-effective, and freely available Urtica was investigated. The morphology of the adsorbent surface and the nature of the possible Urtica and MB interactions were examined using SEM analysis and the FTIR technique, respectively. Various factors affecting MB adsorption such as adsorption time, initial MB concentration, temperature, and solution pH were investigated. The adsorption process was analysed using different kinetic models and isotherms. The results showed that the MB adsorption kinetic follows a pseudo-second-order kinetic model and the isotherm data fit the Langmuir isotherm well. Thermodynamic parameters, such as ΔG°, ΔH°, and ΔS°, were also evaluated, and the results indicated that the adsorption process is endothermic and spontaneous in nature. The MB adsorption capacity of Urtica was found to be as high as 101.01 mg g

AbstractNovel copolymers of poly(aniline-co-m-chloroaniline)-doped dodecylbenzenesulphonic acid (DBSA) with embedded silver nanoparticles were synthesised using the in situ chemical oxidative method. The structural properties of the copolymers were characterised using the UV-VIS and FTIR spectroscopic methods. The crystalline nature of the copolymer was demonstrated by way of the X-ray diffraction (XRD) pattern. Scanning electron microscopy (SEM) revealed the presence of particle agglomerates measuring 50 nm to 100 nm on the surface of the nanocomposites. The electrical conductivity of the copolymer was dependent on the monomer composition and was found to be in the range of 10

Published: April 2015

Abstract
The locality of the northeastern most part of Slovakian Flysch belt belongs to interesting areas in terms of the interpretation of geothermal conditions in mutual relation with the lithosphere structure and their tectonic development. The evaluation of the geothermal energy sources parameters of this locality is likewise worthwhile. The region under study has the centre in position of the borehole Zboj ZB-1 and spreads out Slovakia also in Poland and Ukraine.
Our contribution provides the analyses of existing geothermal data enhanced by the construction of temperature field models corresponding to the global and local aspects that influence the temperature and heat flow density distributions. The analyses are related to the structures and effects of separate phenomena along as well as across the Carpathian arc. The model calculations were carried out both by analytical and numerical methods of solving the heat transfer equations including their steady state forms and transient cases too.
Besides the regional trend of thermal activity decrease in direction from East-Slovakian Basin to the outer Carpathian units the combined local influences are applied: subsurface thermophysical parameters of rock complexes distributions, non-stationary sources from supposed subvolcanic bodies in close surroundings of borehole Zboj ZB-1, and the effects of the hydrological factors. Considering the observed higher thermal activity in arched zone along the Carpathian structures we discussed the thermal effects of rock complexes supposed as a source of regional Carpathian Conductivity Anomaly and the transfer of heat from East-Slovakian Basin to Outer Carpathian Flysch units. The analysis and the modelling results suggest that the mentioned activity is caused by the influences of source type phenomena mainly related to deep fault systems at the margin of the European Platform. That means the anomalies in heat flow density distribution can reach the value 70 mW/m2 and more in the zone above the thermally active deep-fault system with the presence of volcanism and hydrothermal activities.

Published: April 2015

AbstractWe demonstrate the synthesis of star-shaped poly(2-ethyl-2-oxazoline) featuring a porphyrin core starting from alkyne-functionalized porphyrin ([TPP-TB]4) and azide-functionalized poly(2-ethyl-2-oxazoline) (PEtOx-N3) via copper-catalyzed azide-alkyne cycloaddition (CuAAC). The porphyrin core was further utilized for the complexation of either copper or iron within the central cavity. The obtained materials were investigated using a combination of nuclear magnetic resonance spectroscopy, fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, size-exclusion chromatography, and matrix assisted laser desorption/ionization time-of-flight mass spectrometry. In the case of copper, the inclusion of the metal ion was achieved in a one-pot reaction during the CuAAC reaction for attaching the PEtOx-N3 arms.
The Prisms of Management
Authors: Domański Jarosław , Kotarba Wiesław , Krupa Tadeusz 
Published: April 2015

Abstract
This article makes a contribution to the ongoing paradigmatic debate concerning management science, aiming to define more precisely its constructs. At present, within this field there is a lack of definition, of a universally accepted way of seeing reality, which results in a clear deficit in pedagogical identity. Our proposal for a new paradigm is based on three descriptors or constructs (prisms): organization, knowledge, and safety (OKS); in this model, the leading role is played by human.
The “organization” prism, in the classic sense, concerns the organization with an emphasis on the implementation of the personalistic vision of human. The “knowledge” prism includes the technical, social, and economic aspects of the collection, processing, and use of knowledge. The “security” prism is an aspect related to the identification and prevention of crises and threats to the functioning of the OKS triad as a whole.
