Crystalline protein profiling and cry gene detection in Bacillus thuringiensis strains isolated during epizootics in Cydia pomonella L.
Authors: Konecka Edyta , Baranek Jakub , Kaznowski Adam 
Published: July 2015

Abstract
The composition of Bacillus thuringiensis crystalline inclusions was characterized in 18 strains: 12 isolates were obtained from the intestinal tract of Cydia pomonella larvae during epizootics, 2 isolates were cultured from Leucoma salicis larvae taken from their natural populations, and 4 reference strains. The number and molecular mass of B. thuringiensis crystalline proteins (Cry and Cyt) was estimated by the sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). The crystals contained 1-8 proteins with molecular masses of 36-155 kDa. The toxin profiles differed both quantatively and qualitatively. The B. thuringiensis MPU B9 isolate had the highest number and diversity of Cry toxins. The analysis of crystal composition by SDS-PAGE was insufficient to detect groups and subgroups of Cry proteins. We identified 20 groups and 3 subgroups of Cry and Cyt crystalline toxins. Only one epizootic strain harboured cry25. In single reference strains, the cry1H, cry10 and cry25 genes were found. We did not find any correlation between the occurrence of cry genes and electrophoretic protein profiles of crystalline toxins.

Abstract
Mites, and among them especially the Oribatida, are very abundant in bogs, being good bioindicators of various changes, but little is known about their reaction to heavy industrial exploitation of bogs. This study aimed to compare the acarofauna of the edges of small pools located in 2 bogs of Orawa-Nowy-Targ Basin (Kotlina Orawsko-Nowotarska), namely Łysa Puścizna (LP) and Bór Podczerwony (BP), degraded to different degrees by peat exploitation. The area of bog LP has decreased since the end of the 19th century by 34%, while that of BP has decreased during this time drastically (by 68%). Water in both studied pools differed from that in natural bogs, reported in the literature, especially in pH, colour, and oxygen conditions (COD and BOD5), and these differences were more pronounced at BP. The abundance of mites was similar to that observed in natural bogs, and the Oribatida dominated among mites, constituting over 99% of them. The species diversity of Oribatida was low in both pools, but especially in pool BP. In both bogs the aquatic species were the most abundant due to the wet study season. The species structure of Oribatida differed, however, from that reported from natural bogs as well as from each other. At the less degraded bog LP the most abundant was Hydrozetes lacustris (D = 69%), while at bog BP, with worse water parameters, Trimalaconothrus maior highly dominated (D = 93%). This suggests that the latter species is very tolerant to water parameters, being a successful coloniser of degraded bogs.

Published: July 2015

AbstractSeveral Lewis acid ionic liquids (LAILs) with different acidic scales were synthesised and used as catalysts for the synthesis of benzofuranol by condensation of pyrocatechol and 3-chloro-2- methylpropene in one pot. The catalytic activity of these ionic liquids was correlated with their Lewis acidity. Low to moderate conversion with excellent selectivity to benzofuranol was obtained in the presence of the appropriate LAILs. Compared to the two-step synthetic method currently used in industry, a higher yield plateau (81.1 %) of benzofuranol was achieved in the presence of [BMIm][AlCl
Transcriptional profiling of bovine muscle-derived satellite cells during differentiation in vitro by high throughput RNA sequencing

Published: July 2015

AbstractIn this study, we utilized high throughput RNA sequencing to obtain a comprehensive gene expression profile of muscle-derived satellite cells (MDSCs) upon induction of differentiation. MDSCs were cultured in vitro and RNA was extracted for sequencing prior to differentiation (MDSC-P), and again during the early and late differentiation (MDSC-D1, and MDSC-D3, respectively) stages. Sequence tags were assembled and analyzed by digital gene expression profile to screen for differentially expressed genes, Gene Ontology annotation, and pathway enrichment analysis. Quantitative real-time PCR was used to confirm the results of RNA sequencing. Our results indicate that certain of genes were changed during skeletal muscle cell development, cell cycle progression, and cell metabolism during differentiation of bovine MDSCs. Furthermore, we identified certain genes that could be used as novel candidates for future research of muscle development. Additionally, the sequencing results indicated that lipid metabolism might be the predominant cellular process that occurs during MDSC differentiation.
Enhanced stability of PVA electrospun fibers in water by adding cellulose nanocrystals

Published: July 2015

Abstract
The solubility of electrospun poly(vinyl alcohol) nanofiber mats (PVAES-NFM) is strongly influenced by loading with nanocellulose (NC). The NC was derived from hemp shives obtained by steam explosion autohydrolysis followed by water and alkaline extraction, ball milling, and ultrasonication treatments. It was demonstrated for the first time that PVAES-NFM does not disintegrate in aqueous medium after simple adding of NC without any additional chemical or physical modification (PVAES-NFMNC). The structural and thermal studies on PVAES-NFMNC indicated that enhanced stability in aqueous medium can be explained by interactions between surface groups of NC and PVA macromolecules as well as by reinforcing the effect of NCs. The experimental findings could be important for filtration applications in environments with high relative humidity.
The role of the Lowe syndrome protein OCRL in the endocytic pathway
Authors: Sharma Shruti , Skowronek Agnieszka , Erdmann Kai Sven 
Published: July 2015

AbstractMutations of the inositol-5-phosphatase OCRL cause Lowe syndrome and Dent-II disease. Both are rare genetic disorders characterized by renal defects. Lowe syndrome is furthermore characterized by defects of the eye (congenital cataracts) and nervous system (mental disabilities, hypotonia). OCRL has been localised to various endocytic compartments suggesting impairments in the endocytic pathway as possible disease mechanism. Recent evidence strongly supports this view and shows essential roles of OCRL at clathrin coated pits, transport of cargo from endosomes to the trans-Golgi network as well as recycling of receptors from endosomes to the plasma membrane. In particularin vitroandin vivoevidence demonstrates an important role of OCRL in recycling of megalin, a multi-ligand receptor crucial for reabsorption of nutrients in the proximal tubulus, a process severely impaired in Lowe syndrome patients. Thus defects in the endocytic pathway are likely to significantly contribute to the kidney phenotype in Lowe syndrome and Dent-II disease.
Variable Selection for Confounder Control, Flexible Modeling and Collaborative Targeted Minimum Loss-Based Estimation in Causal Inference
Authors: Schnitzer Mireille E. , Lok Judith J. , Gruber Susan 
Published: July 2015

Abstract
This paper investigates the appropriateness of the integration of flexible propensity score modeling (nonparametric or machine learning approaches) in semiparametric models for the estimation of a causal quantity, such as the mean outcome under treatment. We begin with an overview of some of the issues involved in knowledge-based and statistical variable selection in causal inference and the potential pitfalls of automated selection based on the fit of the propensity score. Using a simple example, we directly show the consequences of adjusting for pure causes of the exposure when using inverse probability of treatment weighting (IPTW). Such variables are likely to be selected when using a naive approach to model selection for the propensity score. We describe how the method of Collaborative Targeted minimum loss-based estimation (C-TMLE; van der Laan and Gruber, 2010 [27]) capitalizes on the collaborative double robustness property of semiparametric efficient estimators to select covariates for the propensity score based on the error in the conditional outcome model. Finally, we compare several approaches to automated variable selection in low- and high-dimensional settings through a simulation study. From this simulation study, we conclude that using IPTW with flexible prediction for the propensity score can result in inferior estimation, while Targeted minimum loss-based estimation and C-TMLE may benefit from flexible prediction and remain robust to the presence of variables that are highly correlated with treatment. However, in our study, standard influence function-based methods for the variance underestimated the standard errors, resulting in poor coverage under certain data-generating scenarios.
K Niektorým Aspektom Termínu „Archaizmus “
Authors: Kováčová Viera 
Published: July 2015

Abstract
Main focus of this paper is the issue of notional variability of the term “archaism” which occurs in historical-linguistic and dialectological works with a common denominator - dialects. The basis of the registered notional variability (1. Linguistic phenomenon which carries over from an earlier linguistic period - residual archaism; 2. Dialectal phenomenon which represents older state of language - relict archaism 3. Dialectal phenomenon which is currently receding - synchronic, structural archaism) lies in differences resulting from diachronic (the age of the linguistic phenomenon, diachronic resultativity, residuality/relictness) and synchronic (obsolescence of the linguistic phenomenon, synchronic processuality) approach to the language and its dynamics. The variability of the term archaism according to the approach used (the aspect of the national language, its development vs. the aspect of dialectal system and its structure) is illustrated on the example of linguistic phenomena characteristic for Sotak dialects of the north-eastern Zemplín. During the process of selection of examples from Sotak dialects the fact that the structure of this dialectal system includes, in a concentrated form, linguistic phenomena reflecting an older developmental state of the Slovak language (archaisms from the point of view of national language and its development) was taken into consideration.

Published: July 2015

Abstract
The use of sensors has had an enormous increment in the last years, becoming a valuable tool in many different areas. In this kind of scenario, the quality of data becomes an extremely important issue; however, not much attention has been paid to this specific topic, with only a few existing works that focus on it. In this paper, we present a proposal for managing data streams from sensors that are installed in patients’ homes in order to monitor their health. It focuses on processing the sensors’ data streams, taking into account data quality. In order to achieve this, a data quality model for this kind of data streams and an architecture for the monitoring system are proposed. Moreover, our work introduces a mechanism for avoiding false alarms generated by data quality problems.

Authors: Kučera Dalibor , Havigerová Jana M. 
Published: July 2015

Abstract
The paper deals with the issue of computational psycholinguistic analysis (CPA) and its experimental application in basic psychological and pedagogical assessment. CPA is a new method which may potentially provide interesting, psychologically relevant information about the author of a particular text, regardless of the text’s factual (semantic) content and without the need to obtain additional materials. As part of our QPA-FPT research we studied the link between the linguistic form of a text by Czech college students and their personality characteristics obtained from a psychodiagnostic test battery. The article also discusses the basis of the method, opportunities for practical application and potential use within psychological and pedagogical disciplines
Asking better questions! A review of the pedagogical strategies used in one senior level award in Scotland
Authors: Thorburn Malcolm , Seatter Katrina 
Published: July 2015

Abstract
Previous related research on teaching effectiveness in one senior level award - Higher Still Physical Education (HSPE) in Scotland - revealed a number of extended challenges in adopting the practical experiential teaching and learning approaches advised. However, these studies were restricted by lack of observation of teaching and learning in action and of detailed analysis of the types and timings of questions asked. The present study addressed these limitations. Data were collected through observations of teaching, questionnaire responses on the uses of discussions by pupils and teachers and semi-structured teacher interviews. Findings revealed that there were encouraging signs of a broad range of purposeful question techniques being used in practical sessions. However, there was still a lack of full teacher trust in these approaches, despite high pupil endorsement for their usage. We conclude that perceived subject content and external assessment demands continue to constrain pedagogical strategies in HSPE.
Probabilistic and statistical properties of moment variations and their use in inference and estimation based on high frequency return data
Authors: Lee Kyungsub 
Published: July 2015

AbstractWe discuss the probabilistic properties of the variation based third and fourth moments of financial returns as estimators of the actual moments of the return distributions. The moment variations are defined under non-parametric assumptions with quadratic variation method but for the computational tractability, we use a square root stochastic volatility model for the derivations of moment conditions for estimations. Using the S&P 500 index high frequency data, the realized versions of the moment variations is used for the estimation of a stochastic volatility model. We propose a simple estimation method of a stochastic volatility model using the sample averages of the variations and ARMA estimation. In addition, we compare the results with a generalized method of moments estimation based on the successive relation between realized moments and their lagged values.
Materia mystica. Próba introspekcji w kolorach złota i czerni* / Materia Mystica. An Introspection in Black and Gold
Authors: Snoch-Pawłowska Alicja 
Published: July 2015

AbstractThe article is an attempt to combine reflection on the mystical side of artistic activity with the author’s self-comment on her creative work in graphic art. The discourse shows multi-aspectual thoughts on the secret of the act of creation and the matter itself that serves art, based on the philosophical background of different religious, cultural and worldview traditions; it also touches upon the sphere of self-cognition, symbolism, and transcendence. The author’s narrative is accompanied by the thoughts of inter alia William Blake, Samuel Coleridge, Stanisław Fijałkowski, Hildegard of Bingen, Carl Gustav Jung, Kabir, Wassily Kandynsky, Paul Klee, Czesław Miłosz, Meister Eckhard, Rainer Maria Rilke, Andrzej Strumiłło, St. John of the Cross, and Zhuangzi. These considerations are combined with the analytical explication of the author’s selected works and with an attempt to introspectively look into herself.The author examines the following: understanding of the concept and phenomenon of matter (Materia - proch ziemi i kwantowa pustka [Matter - the Dust of Earth and Quantum Void]); mystical and spiritual aspects of art (Mistyka - ulotność wizji i realność duchowości [Mysticism - Transience of Vision and the Reality of the Spiritual]); the world (identified with the matter of creation) of inner experiences of her own artistic imagination (Materia tworzenia [Matter of Creation]); symbolic-formal features of her own graphic works (W granicach formy [Within the Form]); and the unfathomable problem of cognition and self-cognition through art (Laboratorium sztuki i sztuka przemiany [Laboratory of Art and the Art of Transformation]).
Experimental approach towards the water contact angle value on the biomaterial alloy Ti6Al4V
Authors: Hierro-Oliva Margarita , Gallardo-Moreno Amparo Maria , Rodríguez-Cano Abraham , Bruque Jose Morales , González-Martín Maria Luisa 
Published: July 2015

AbstractIn the biomedical field, water contact angle is a useful gauge to follow how a biomaterial surface would interact with the surrounding water-like physiological environment. Ti6Al4V alloy is widely used in orthopedic applications. Nevertheless, the values of its water contact angle reported in the literature show a large dispersion, from 40° up 80°. However, in addition to the expected dependence of the surface wettability on preliminary treatments, the values of the water contact angle on the pristine Ti6Al4V alloy suffers from an important variability and lack of reproducibility. The present research pays attention to this difficulty and proposes a simple experimental procedure to ensure adequate contact angle reproducibility. Controlled passivation growth in mild underwater conditions of freshly polished disks, followed by ultrasonic washing, avoiding the rubbing of the surface, gives average water contact angles of 80° with very low standard deviations also among samples from the same batch.
Effect of Pluronics and surfactant adsorption onto dolomite suspension zeta potential and stability
Authors: Kozak Anna , Sadowski Zygmunt 
Published: July 2015

AbstractTwo kinds of Pluronics (PEO-PPO-PEO triblock copolymers) were used in these studies. They have mixed with anionic surfactant (sodium oleate). The adsorption isotherms of surfactant and copolymer-surfactant mixture onto dolomite have been determined. The adsorbed amount of the Pluronics increases with increasing concentration and reaches plateau. An increase of adsorbed amounts of anionic surfactant onto the mineral surfaces (dolomite) has been observed at the presence of Pluronic copolymers. The adsorption effect of triblock copolymers has been investigated on the zeta potential of dolomite at the water suspension. The interaction of anionic surfactant with copolymers causes a decrease of zeta potential to small amount due to the deformation of double electrical layer. The adsorbed non-ionic Pluronic layer partially screens the surface charge of mineral particles, and thus, reduces the zeta potential. On the other hand, the adsorption of anionic surfactant and copolymer caused a decrease of negative value of zeta potential both investigated minerals. The stability of dolomite suspension depends on the both copolymer and sodium oleate concentrations.

Published: July 2015

AbstractActivity coefficients at infinite dilution of the aqueous solutions of nonionic hydrocarbon surfactants, p-(1,1,3,3- tetramethylbutyl) phenoxypoly(ethylene glycols), Triton X-100 (TX100) and Triton X-165 (TX165), fluorocarbon surfactants, Zonyl FSN-100 (FSN100) and Zonyl FSO-100 (FSO100) and their ternary mixtures were determined from the Gracia-Fadrique et al. method for non-volatile compounds. The values of activity coefficients were calculated taking into account the surface tension data of the studied systems at 293K and compared to those determined on the basis of the values of the contact angle of solutions on the polytetrafluoroethylene (PTFE) and polymethyl methacrylate (PMMA) surfaces and the solid-liquid interface tension.
Sugar-based surfactants as alternative to synthetic ones
Authors: Mańko Diana , Zdziennicka Anna 
Published: July 2015

AbstractFrom year to year natural surfactants are gaining ever growing awareness because of their valuable properties (in the absence of negative impact on the environment, as with the use of synthetic surface active agents). In the group of surfactants of natural origin there are surface active agents produced by microorganisms (biosurfactants) or compounds having a natural part (hydrophilic head and/or hydrophobic tail) [1]. This review includes the short characteristic of surfactants with sugar-head group in their structure called sugar-based surfactants. The structure, properties and some applications of these surfactants are described in this paper.
The Glacial History of the Svalberd Archipelago from Late Vistulian to the Present Time / Historia zlodowacenia archipelagu Svalbard od późnego vistulianu do współczesności
Authors: Ćwiąkała Joanna , Moskalik Mateusz , Rodzik Jan , Zagórski Piotr 
Published: July 2015

AbstractThe glacial history of the Svalbard archipelago is often a hot topic for researches, but the articles usually refer to a particular piece of Svalbard. The authors of this work studied many scientific articles based on the researches to find and collect this history. Svalbard archipelago is located in the Arctic, at the edge of the continental shelf of Europe. The end of shelf boundary noted occurrence of ice caps in the past glaciations. In turn, the main elements of the landscape of the archipelago are glaciers that are currently in a recession. Spitsbergen (the biggest island of the archipelago) sets the limit of Pleistocene glaciations, and the current state of glaciers allows determining the place where the recession is intense. The main aim of the authors in this study is to show this history only from the late Vistulian to the late Holocene (the beginning of 21st century). Interstadials and Stadials start time varies, as their duration in different places, according to various authors. It is very hard to collect all information and describe this history. By knowing the history of glaciation, we can distinguish in the late Vistulian: Last Glacial Maximum (LGM), Bølling/Older Dryas/Allerød and Younger Dryas (YD). LGM was the stadial in which was the maximum extent of ice sheet in late Vistulian. After this period, ice sheet began to retreat from the continental shelf. In turn, YD was the stadial in which the last advance of glaciers took place, about 11 000 years BC. In the Holocene we can distinguish Holocene Climatic Optimum (in the meantime short Cooling Holocene), Revdalen Stadial, Medieval Warm Period, Little Ice Age (LIA) and 20th century warming. The maximum extent of glaciers in Holocene was in LIA. In LIA, the extent of glaciers was bigger than in YD. In 20th century a warming started and continues until now.
