Südtiroler Sprachenprivileg für Zivilprozesse gilt auch für EU-Bürger ohne Wohnsitz in Südtirol!
Authors: Kramme Malte
Published: July 2016

The ECJ states in its decision of 27 March 2014 (C-322/13) that the non-discrimination principle (article 18 TFEU) and the principle of free movement of persons (article 21 TFEU) preclude a rule of national law granting a right to use a language other than the official language of the Member State in civil proceedings brought before the courts of a Member State which are situated in a specific territorial entity, only to citizens of that State who are domiciled in the same territorial entity. The case note demonstrates that this ruling is a result of a very broad interpretation of the two principles in question.
Internationale Zuständigkeit bei der Miete ausländischer Ferienhäuser

Published: July 2016

With its decision of 23 October 2012 the Federal Supreme Court (Bundesgerichtshof = BGH) enabled German courts to judge very tenant-friendly in questions of international jurisdiction concerning international vacation house tenancies.

However, the relevant literature on Article 22 No. 1 Brussels I Regulation shed light on issues of this decision especially concerning the interpretation of the term “tenancy”. Here, the term tenancy is understood in a wider way.

In contrast, the Federal Supreme Court argues for a very restrictive interpretation of the term tenancy in Article 22 No. 1 Brussels I Regulation, and by that loses sight of the ECJ’s exclusive right of interpretation of law-terms of the Regulation. This results in an interpretation of the term “tenancy” particularly contradicting the ECJ’s decision in “Dansommer”.

Although the decision of the Federal Supreme Court facilitates access to extensive legal protection for German tenants of vacation houses based abroad, it is arguable whether the interpretation of the term tenancy is in line with the adjudication of the ECJ.

The occurrence of nematodes of the family Longidoridae was investigated in soil samples collected from cultivated and wild olives and grapevines in Crete. The first-stage juveniles of Xiphinema cretense and X. herakliense are described for the first time. The species X. israeliae, X. cretense, X. herakliense and Longidorus pseudoelongatus, previously recorded exclusively from olives in Crete, are herein reported in the rhizosphere of grapevines. Also L. iranicus is reported for the first time in cultivated olive, while X. italiae and L. closelongatus are reported for the first time in wild olive in Crete. Data on the occurrence of phytoparasitic nematode species in cultivated olives, wild olives and grapevines are updated with those previously published.
Insights into K-Ras 4B regulation by post-translational lysine acetylation
Authors: Knyphausen Philipp , Lang Franziska , Baldus Linda , Extra Antje , Lammers Michael
Published: July 2016

Ras is a molecular switch cycling between an active, GTP-bound and an inactive, GDP-bound state. Mutations in Ras, mostly affecting the off-switch, are found in many human tumours. Recently, it has been shown that K-Ras 4B is targeted by lysine acetylation at K104. Based on results obtained for an acetylation mimetic Ras mutant (K104Q), it was hypothesised that K104-acetylation might interfere with its oncogenicity by impairing SOS-catalysed guanine-nucleotide exchange. We prepared site-specifically K104-acetylated K-Ras 4B and the corresponding oncogenic mutant protein G12V using the genetic-code expansion concept. We found that SOS-catalysed nucleotide exchange, also of allosterically activated SOS, was neither affected by acetylation of K104 in wildtype K-Ras 4B nor in the G12V mutant, suggesting that glutamine is a poor mimetic for acetylation at this site. In vitro, the lysine-acetyltransferases CBP and p300 were able to acetylate both, wildtype and G12V K-Ras 4B. In addition to K104 we identified further acetylation sites in K-Ras 4B, including K147, within the important G5/SAK-motif. However, the intrinsic and the SOS-catalysed nucleotide exchange was not affected by K147-acetylation of K-Ras 4B. Finally, we show that Sirt2 and HDAC6 do neither deacetylate K-Ras 4B if acetylated at K104 nor if acetylated at K147 in vitro.
Human 20S proteasome activity towards fluorogenic peptides of various chain lengths
Authors: Rut Wioletta , Drag Marcin
Published: July 2016

The proteasome is a multicatalytic protease responsible for the degradation of misfolded proteins. We have synthesized fluorogenic substrates in which the peptide chain was systematically elongated from two to six amino acids and evaluated the effect of peptide length on all three catalytic activities of human 20S proteasome. In the cases of five- and six-membered peptides, we have also synthesized libraries of fluorogenic substrates. Kinetic analysis revealed that six-amino-acid substrates are significantly better for chymotrypsin-like and caspase-like activity than shorter peptidic substrates. In the case of trypsin-like activity, a five-amino-acid substrate was optimal.
Effectiveness of a modified dialectical behaviour therapy for adolescents within a stepped-care model
Authors: Khalid-Khan Sarosh , Segal Shira C. , Jopling Ellen N. , Southmayd Kathy , Marchand Patricia
Published: July 2016

Objective:

Early intervention with evidence-based treatment is important to halt the progression from early manifestations of personality disorder traits to adult personality disorders. The purpose of this study is to evaluate dialectical behaviour therapy (DBT) modified for an adolescent population with borderline personality disorder (BPD), offered within a stepped-care model.

Methods:

Seven adolescents (M=1, F=6, Mage=16.86) diagnosed with either BPD or BPD traits participated in a modified 15-week DBT group. The group was offered within a stepped-care model, which required participants to have previously completed an 8-week distress-tolerance module. Pre/post scores on self-report measures of BPD symptomatology, including impulse control, emotional regulation and awareness, anxiety, depression, and substance use, were collected.

Results:

Participants showed a post-treatment decrease in anxiety symptoms (large effect size) and disruptive behaviours (medium effect size). There was also an increase in emotional symptoms (medium effect size) and hyperactivity/inattention (medium effect size).

Conclusion:

The modified DBT group shows promise in alleviating symptoms of anxiety and some of the disruptive behaviours associated with BPD. The increase in emotional symptoms may be due to the expressive nature of DBT, and may contribute to their eventual therapeutic processing in the next step of the program.
Ontogenesis of the Dative Case in the Light of Natural Morphology and Cognitive Linguistics
Authors: Kesselová Jana
Published: July 2016

In the framework of the natural morphology (The types of homomorphism; J. Dolník, 2005) and cognitive linguistics (the dative case as the grammatical exponent of the target person’s role; E. Dąbrowska, 1997), the paper deals with the dative case in early speech development (during the first 3 years of child’s life). The study presents the results of the research into grammatical forms, case meanings and pragmatic functions. The key question is this: which dative case structures children acquire preferentially? The research is based on the combination of qualitative (audiovisual recordings of three children, coding of transcripts) and quantitative (1065 parental assessments) methods. The research leads to conclusions on three levels: (a) The form: grammatical forms of the dative case with segmental and defective homomorphism are typical for preferentially acquired forms. (b) The semantics: dative of benefit and dative of direction can be interpreted as case meanings that create the core of the dative case’s early semantics. (c) The pragmatics: children use the dative case preferentially in utterances with pragmatic function: con-situational information, disagreement, answer, will and challenge. It means that the dative case is primarily used in the developmentally oldest functions. The research broadens the understanding of speech ontogenesis and contributes to language explanation that is compatible with the process of its acquisition.
Status of Precedent Units in the System of Intertextual Means of Contemporary Ukrainian Media Discourse
Authors: Sakharuk Inna V.
Published: July 2016

The article is devoted to the determination of the status of precedent units (precedent names and expressions) in the system of intertextual means of contemporary Ukrainian media discourse. There was analyzed the phenomenon of intertextuality in the broad and narrow senses; the functions of precedent units that realize the main media discourse purpose of informing and influence were revealed.

The analysis of the essence of precedence in linguistics gives grounds to distinguish three types of precedent phenomena: precedent texts, situations and personalities, as well as two types of precedent units: precedent names and expressions. The connection of precedent units and related concepts – winged words, aphorisms and idioms – was established.

Based on a comparative analysis of the views of European and American scholars on the phenomena of intertextuality and precedence in linguistics there were singled out the means of direct and indirect appeal to prototext, which enroll the quotations and references, as well as the precedent units and allusions respectively.
Perspectives of the Language Policy of the EU
Authors: Lejsková Alena
Published: July 2016

In the territory of Europe, a unique political, economic and linguistic formation that does not have any analogy in the world has come into being. The principal problem which the member states of European Union will face in future is the problem of communication, i.e. the language policy of EU. Its basic principle is the multilingualism embedded in the initial documents of the EU. The practical implementation of multilingualism within the EU institutions and its bodies is a real problem that must be resolved with each subsequent expansion of the EU, though this actually depends on the position of languages within the EU itself. The opinions of the EU citizens show their approving the standpoint of European language policy focused on multilingualism. The possible differences of opinions concern with the financial flows in the language market, as well as the dynamics of the position of individual languages within the Union. Foreign language teaching as a part of EU language policy is by its citizens considered crucial for two aspects – the mutual understanding between the citizens and states of the Union and the better assertion in the labour market.
Thrombus Aspiration, from “Heart to Soul”
Authors: Iancu Adrian , Rafiroiu Dan , Dregoesc Ioana
Published: July 2016

Microvascular obstruction (MVO) is one of the most frequent complications encountered during primary percutaneous coronary intervention in patients with acute ST-segment elevation myocardial infarction. The embolization of thrombotic material seems to be the leading cause of MVO, and many clinical trials have demonstrated that thrombus aspiration (TA) may be a useful means of preventing this phenomenon. Continuous advancements in technology have contributed to the development of various devices for thrombus aspiration. However, a review of the literature indicates that there is disagreement regarding the role of TA in the prevention and treatment of MVO. TA is increasingly used in the treatment of acute stroke in patients who are admitted to the hospital within eight hours from the onset of symptoms. This review presents the current knowledge regarding the role of TA in the prevention of MVO.

Authors: Lanctôt Dominique , Dupuis Gilles , Marcaurell Roger , Anestin Annélie S. , Bali Madan
Published: July 2016

Background

Several cognitive behavioral interventions have been reported to reduce psychological symptoms in breast cancer (BC) patients. The goal of this study was to evaluate the effects of a yoga intervention in reducing depression and anxiety symptoms in BC patients.

Methods

This study was a randomized, partially blinded, controlled trial comparing a standardized yoga intervention to standard care. It was conducted at three medical centers in Montreal, Canada. Eligible patients were women diagnosed with stage I–III BC receiving chemotherapy. Participants were randomly assigned to receive yoga intervention immediately (experimental group, n=58) or after a waiting period (n=43 control group). The Bali Yoga Program for Breast Cancer Patients (BYP-BC) consisted of 23 gentle Hatha asanas (poses), 2 prayanamas (breathing techniques), shavasanas (relaxation corpse poses) and psychoeducational themes. Participants attended eight weekly sessions lasting 90 min each and received a DVD for home practice with 20- and 40-min sessions. Participants in the wait list control group received standard care during the 8-week waiting period.

Results

A total of 101 participants took part in the final intention-to-treat analyses. The repeated measures analyses demonstrated that depression symptoms increased in the control group (p=0.007), while no change was reported in the BYP-BC group (p=0.29). Also, depression symptoms decreased in the WL control group after receiving the BYP-BC intervention (p=0.03). Finally, there was no statistical significance in terms of anxiety symptoms (p=0.10).

Conclusions

Results support the BYP-BC intervention as a beneficial means of reducing and preventing the worsening of depression symptoms during chemotherapy treatment.
A comparative study of the antacid effect of raw spinach juice and spinach extract in an artificial stomach model
Authors: Panda Vandana Sanjeev , Shinde Priyanka Mangesh
Published: July 2016

Background

Spinacia oleracea known as spinach is a green-leafy vegetable consumed by people across the globe. It is reported to possess potent medicinal properties by virtue of its numerous antioxidant phytoconstituents, together termed as the natural antioxidant mixture (NAO). The present study compares the antacid effect of raw spinach juice with an antioxidant-rich methanolic extract of spinach (NAOE) in an artificial stomach model.

Methods

The pH of NAOE at various concentrations (50, 100 and 200 mg/mL) and its neutralizing effect on artificial gastric acid was determined and compared with that of raw spinach juice, water, the active control sodium bicarbonate (SB) and a marketed antacid preparation ENO. A modified model of Vatier’s artificial stomach was used to determine the duration of consistent neutralization of artificial gastric acid for the test compounds. The neutralizing capacity of test compounds was determined in vitro using the classical titration method of Fordtran.

Results

NAOE (50, 100 and 200 mg/mL), spinach juice, SB and ENO showed significantly better acid-neutralizing effect, consistent duration of neutralization and higher antacid capacity when compared with water. Highest antacid activity was demonstrated by ENO and SB followed by spinach juice and NAOE200. Spinach juice exhibited an effect comparable to NAOE (200 mg/mL).

Conclusions

Thus, it may be concluded that spinach displays significant antacid activity be it in the raw juice form or as an extract in methanol.

Published: July 2016

Introduction: Percutaneous coronary intervention is the first therapeutic choice in the treatment of symptomatic coronary artery disease and Multi-Slice Computed Tomography Coronary Angiography (MSCT-CA) is a new non-invasive diagnostic tool in the follow-up of these patients. The aim of our study was to evaluate the rate of in-stent restenosis (ISR), to identify the predictive factors for ISR at 1 year after PCI and to assess the progression of non-culprit lesions, using a MSCT-CA follow-up.

Material and methods: The study included 30 patients with acute coronary syndrome treated with one BMS implantation. The patients were divided into Group A (9 patients) presenting ISR and Group B (21 patients) without ISR at 1 year MSCT-CA follow-up.

Results: ISR lesions were mostly localized on the LAD (45%). No significant difference between the study groups was identified for risk factors, as male gender (77.7% vs. 85.71%, p = 0.62), hypertension (88.8% vs. 95.23%, p = 0.51), smoking status (33.3% vs. 72.22%, p = 0.23), history of CVD (55.5% vs. 47.61%, p >0.99), diabetes (11.11% vs. 19.04%, p >0.99), hyperlipidemia (22.22% vs. 52.38%, p = 0.22), CKD (44.44% vs. 14.28%, p = 0.15), age, triglycerides and SYNTAX Score. A significant difference was recorded in baseline cholesterol level (141.7 ± 8.788 vs. 182.8 ± 12; p = 0.029). Ca Score at 1 year was significantly higher in patients with ISR (603.1 ± 529.3 vs. 259.4 ± 354.6; p = 0.005). 66.67% of patients from Group A presented significant non-culprit lesions at baseline vs. 23.81% in Group B (p = 0.041).

Conclusions: MSCT-CA is a useful non-invasive diagnostic tool for ISR in the follow-up of patients who underwent primary PCI for an acute coronary syndrome. The presence of significant non-culprit lesions at the time of the primary PCI could be a predictive factor for ISR. A Ca Score >400 determined at 1-year follow-up is associated with a higher rate of ISR, and could be considered a significant cardiovascular risk factor for this group of patients. Further studies are required in order to elucidate the role of various imaging biomarkers in predicting the development of ISR.

Authors: Blesneac Cristina , Şuteu Carmen Corina , Pop Marian , Togănel Rodica
Published: July 2016

Unilateral pulmonary artery agenesis is a rare congenital anomaly, that may develop in isolation, or in association with other congenital cardiovascular anomalies, such as tetralogy of Fallot, septal defects, right-sided aortic arch, or pulmonary atresia. Left-sided pulmonary artery agenesis is less frequent than the right-sided one. Diagnosis of unilateral pulmonary artery agenesis can be difficult. We report the case of a 15 year-old boy who presented with reduced exercise tolerance, shortness of breath and cyanosis. He was diagnosed with left pulmonary artery agenesis, associated with subaortic-ventricular septal defect, right-sided aortic arch, and severe pulmonary arterial hypertension (PAH), that precluded the surgical repair. Pulmonary vasodilator therapy was initiated in this case. The mortality rate of this rare anomaly is high due to its complications. It is essential to establish an early and correct diagnosis, in order to provide adequate treatment and prevent complications in this disease.
New Properties for Solving the Single-Machine Scheduling Problem with Early/Tardy Jobs
Authors: Allaoua Hemmak , Brahim Bouderah
Published: July 2016

This paper presents a mathematically enhanced genetic algorithm (MEGA) using the mathematical properties of the single-machine scheduling of multiple jobs with a common due date. The objective of the problem is to minimize the sum of earliness and tardiness penalty costs in order to encourage the completion time of each job as close as possible to the common due date. The importance of the problem is derived from its NP-hardness and its ideal modeling of just-in-time concept. This philosophy becomes very significant in modern manufacturing and service systems, where policy makers emphasize that a job should be completed as close as possible to its due date. That is to avoid inventory costs and loss of customer’s goodwill. Five mathematical properties are identified and integrated into a genetic algorithm search process to avoid premature convergence, reduce computational effort, and produce high-quality solutions. The computational results demonstrate the significant impact of the introduced properties on the efficiency and effectiveness of MEGA and its competitiveness to state-of-the-art approaches.
Investigation of Micro-Cracks Susceptibility on Machined Pure Titanium Surface in WEDM Process
Authors: Kumar Anish , Kumar Vinod , Kumar Jatinder
Published: July 2016

This research work presents a comprehensive and quantitative analysis of micro-crack formation, in terms of length and number of micro-cracks formed on the machined surface of pure titanium. The effect of processing parameters on micro-crack formation was studied through scanning electron microscope. The results indicate that the micro-crack formation is the best represented in terms of average crack length. Statistical analysis of the results shows that pulse on time, pulse off time and peak current significantly deteriorate the microstructure of machined surfaces which produces the deeper, wider globules of debris and micro cracks. The compounds like titanium dioxide (rutile) (TiO2), (TiO0.325), Ti2O3, Ilmenite (Fe2Ti4O), titanium carbides (TiC) and copper titanium dioxide (Cu3TiO4) were formed due to phase transformations that were analyzed through X-ray diffraction and energy dispersive X-ray method.

Authors: Lange Jéremy , Cattey Hélène , Plasseraud Laurent
Published: July 2016

Reaction of potassium hydrotris(pyrazol-1-yl)borate (KTp) and n-BuSnCl3 at room temperature led to the quantitative formation of TpSn(Cl)2(n-Bu) (1). Colorless single crystals were obtained from a mixture of toluene/dichloromethane and were characterized as TpSn(Cl)2(n-Bu)·½ toluene. Complex 1 crystallizes in the triclinic P1̅ space group, with Z=2, a=8.0496(8) Å, b=9.4867(9) Å, c=14.2710(14) Å, α=90.365(3)°, β=104.479(3)°, γ=95.066(3)°, and V=1050.60(18) Å3. Its structure exhibits a piano stool conformation involving a distorted octahedral geometry around the central Sn(IV) atom. In the crystal and from a supramolecular point of view, 1 is organized in pairs according to a V-shaped arrangement implicating pyrazolyl rings and through weak intermolecular interactions (π-π, C-H···π, and C-H···Cl). The structural analysis of 1 was completed by infrared and solution NMR spectroscopy measurements as well as elemental analysis, which confirm the X-ray elucidation.

If market repeatability is assumed, it is possible with some real probability to deduct short term market changes by making some calculations. The algorithm, based on logical and statistically reasonable scheme to make decisions about opening or closing position on a market, is called an automated strategy. Due to market volatility, all parameters are changing from time to time, so there is need to constantly optimize them. This article describes a team organization process when researching market strategies. Individual team members are merged into small groups, according to their responsibilities. The team members perform data processing tasks through a cascade organization, providing solutions to speed up work related to the use of remote computing resources. They also work out how to store results in a suitable way, according to the type of task, and facilitate the publication of a large amount of results.

Which One to Choose Multi Focus or Trade-Off Among Competitive Priorities? Evidence from Finnish SMEs
Authors: Timilsina Binod , Forsén Nina , Takala Josu , Malek Nurul Aida Abdul
Published: July 2016

This paper examines the relationship between business environment, competitiveness and firm performance considering a survey data from three consecutive years: 2013-2015. The comparative analysis showed that over these years business environment, competitiveness and firm performance of Finnish SMEs are slowly deteriorating. Results from correlation analysis revealed that business environment, competitiveness and firm performance are positively correlated. However, the relationships between these variables are not consistent in respect to competitive priorities indicating a dynamic nature of cost, quality, time, and flexibility dimensions. Besides these findings our analysis acknowledged that to improve firm performance, irrespective to the choice of competitive priority, SMEs should pay more attention to their competitiveness rather than blaming the business environment. The paper concludes that simultaneous use of competitive priority dimensions might be more favorable as a source of competitiveness and competitive advantage to improve firm performance. However, the managers are encouraged to compare the results, findings and concepts presented in this paper among themselves and comprehend the specific answer to the question posed in the title.
On Systems of Independent Sets

Published: July 2016

The classical probability that a randomly chosen number from the set {n ∈ N : n ≤ n0} belongs to a set A ⊆ N can be approximated for large number n0 by the asymptotic density of the set A. We say that the events are independent if the probability of their intersection is equal to the product of their probabilities. By analogy we define the independence of sets. We say that the sets are independent if the asymptotic density of their intersection is equal to the product of their asymptotic densities. In the article is described a generalisation of one of the criteria of independence of sets and one interesting case in which sets are not independent

Limit Theorems for the Counting Function of Eigenvalues up to Edge in Covariance Matrices
Authors: Xie Junshan
Published: July 2016

We consider the number of eigenvalues which fall into an interval for the complex sample covariance matrices. The central limit theorem and a moderate deviation principle are established when the endpoint of the interval is close to the edge of the spectrum. The proofs depend on the Four Moment Theorem about the local statistics of eigenvalues up to edge, and the rigidity theorem of the eigenvalues for sample covariance matrices.
Complexities of Relational Structures
Authors: Hartman David , Hubička Jan , Nešetřil Jaroslav
Published: July 2016

The relational complexity, introduced by G. Cherlin, G. Martin, and D. Saracino, is a measure of ultrahomogeneity of a relational structure. It provides an information on minimal arity of additional invariant relations needed to turn given structure into an ultrahomogeneous one. The original motivation was group theory. This work focuses more on structures and provides an alternative approach. Our study is motivated by related concept of lift complexity studied by Hubička and Nešetřil.

Published: July 2016

Let α denote an infinite cardinal or ∞ which is used to signify no cardinal constraint. This work introduces the concept of an αcc-Baer ring and demonstrates that a commutative semiprime ring A with identity is αcc-Baer if and only if Spec(A) is αcc-disconnected. Moreover, we prove that for each commutative semprime ring A with identity there exists a minimum αcc-Baer ring of quotients, which we call the αcc-Baer hull of A. In addition, we investigate a variety of classical α-Baer ring results within the contexts of αcc-Baer rings and apply our results to produce alternative proofs of some classical results such as A is α-Baer if and only if Spec(A) is α-disconnected. Lastly, we apply our results within the contexts of archimedean f-rings.

In this paper, we define the concepts of the radical of an ideal and a primary ideal in posets. Further, the analogue of the first and the second uniqueness theorems regarding primary decomposition of an ideal are obtained. In the last section, we prove that if an ideal in a poset Q has a minimal primary decomposition, then the diameter of the corresponding zero-divisor graph with respect to this ideal is exactly equal to three.
The Family F of Permutations of ℕ
Authors: Wituła Roman
Published: July 2016

The paper is sacrificed to discussing the property of some special subfamily F of the family of all permutations of ℕ, especially in the context of the fundamental properties of families C and D of the, so called, convergent and divergent permutations, in other words, permutations preserving or not preserving the convergence of the rearranged real series, respectively. Family F is the subgroup of the group G generated by C. In the paper we will prove, among others, that F ⊂ C−1 ◦ C and F \ (C ◦ C−1) ≠ ∅. So, in particular we have G ≠ C◦C−1. The family F is neither the subset nor superset of any of the families C, D and C−1. By using the permutations belonging to the family F we receive the strengthening of some Kronrod’s theorems (which are the generalizations of the Riemann Derangement Theorem).

Published: July 2016

The regular arrangement of metal nanoparticles influences their plasmonic behavior. It has been previously demonstrated that the coupling between diffracted waves and plasmon modes can give rise to extremely narrow plasmon resonances. This is the case when the single-particle localized surface plasmon resonance (λ
LSP) is very close in value to the Rayleigh anomaly wavelength (λ
RA) of the nanoparticles array. In this paper, we performed angle-resolved extinction measurements on a 2D array of gold nano-cylinders designed to fulfil the condition λ
RA<λ
LSP. Varying the angle of excitation offers a unique possibility to finely modify the value of λ
RA, thus gradually approaching the condition of coupling between diffracted waves and plasmon modes. The experimental observation of a collective dipolar resonance has been interpreted by exploiting a simplified model based on the coupling of evanescent diffracted waves with plasmon modes. Among other plasmon modes, the measurement technique has also evidenced and allowed the study of a vertical plasmon mode, only visible in TM polarization at off-normal excitation incidence. The results of numerical simulations, based on the periodic Green’s tensor formalism, match well with the experimental transmission spectra and show fine details that could go unnoticed by considering only experimental data.
Nanofibers based on chitin: a new functional food
Authors: Azuma Kazuo , Ifuku Shinsuke
Published: July 2016

Chitin (β-(1-4)-poly-N-acetyl-D-glucosamine) is widely distributed in nature. A method for the preparation of chitin nanofibers (CNFs) is reported. CNFs are considered to have several potential applications because they have useful properties such as high specific surface area and porosity. More recently, beneficial effects of CNF as functional foods were reported. First, the anti-inflammatory effect of oral administration of chitin CNFs was demonstrated in a mouse model of inflammatory bowel disease (IBD). It was found that CNFs improved clinical symptoms and suppressed IBD. CNFs decreased the areas with nuclear factor-κB (NF-κB) staining in colon tissue. Second, the anti-obesity effects of surface-deacetylated chitin nanofibers (SDACNF) in a mouse model of high-fat diet-induced obesity was evaluated. SDACNFs suppressed the increase in body weight produced by the high-fat diet; however, CNFs did not suppress such weight gain. SDACNFs decreased serum levels of leptin. These results suggest that CNF and SDACNF are promising functional foods for patients with IBD or obesity.
Improving heat aging and mechanical properties of fluoroelastomer using carbon nanotubes
Authors: Heidarian Javad , Hassan Aziz
Published: July 2016

Carbon nanotube (CNT)-, carbon black (CB)-filled fluoroelastomer (FE) and unfilled-FE compounds were prepared (CNT/FE, CB/FE and FE). The compounds were subjected to heat air aging and characterized by tensile test and X-Ray Diffraction (XRD) analysis. Results show that CNT improved tensile properties of FE before and after aging. All samples show stress induced crystallization (SIC) during tension. XRD results show that under all conditions, the crystals were in the form of γ-phase. For both aged and un-aged specimens, the degree of crystallinity (Xc) is low. After tensile stretching, Xc of un-aged specimens increases tremendously, with larger crystal size. Under the same conditions, the order of elongation at break (EL) was FE > CB/FE > CNT/FE. Normal modulus (NM) and tangent modulus (TM) at the same conditions was in the order of CNT/FE > CB/FE > FE. Tensile strength had the order of CNT/FE > CB/FE > FE.
Characterization of reversed micelles formed in solvent extraction of thorium(IV) by bis(2-ethylhexyl) phosphoric acid. Transforming
from rodlike to wormlike morphology
Authors: Gao Song , Sun Taoxiang , Chen Qingde , Shen Xinghai
Published: July 2016

The reversed micelles formed in solvent extraction of thorium(IV) by bis(2-ethylhexyl) phosphoric acid (HDEHP) in n-heptane were
studied. IR spectra, dynamic/static light scattering and zero shear viscosity measurements indicated that thorium complexes formed
rodlike reversed micelles, and both the size of aggregates and the viscosity of the organic phase increased with the increasing loadage
of thorium(IV). The entanglement of reversed micelles resulted in their transformation to wormlike reversed micelles, inducing the very
high viscosity of the organic phase. The structural composition of thorium complexes was proposed to be Th(DEHP)3(NO3)
according to the results of log -log  plot and job method analysis. Furthermore, molecular modeling was employed to clarify the
structures of reversed micelles as well as the state of water inside. It was found that the complexes linked together via hydrogen
bonding and van der Waals forces and that the existence of NO3

–
and H2O improved the stability of reversed
micelles.

73 year-old man presented to our emergency department with complaint of retrosternal chest pain since 2 day and admitted with diagnosis of unstable angina. He underwent diagnostic coronary angiography in which left circumflex artery (LCX) was not visualized during injection of the left coronary artery; indeed, it was originated, with common origin with RCA, from right coronary sinus of Valsalva. This case report is one of the uncommon cases with aberrant coronary arteries who presented with unstable angina. Moreover, coronary angiography with following coronary angioplasty was performed for him in a challenging course and angle for coronary intervention.
The Triangular Binary Clock
Authors: Pretz Jörg
Published: July 2016

A new idea for a binary clock is presented. It displays the time using a triangular array of 15 lamps each representing a certain amount of time. It is shown that such a geometric, triangular arrangement is only possible because our system of time divisions is based on a sexagesimal system in which the num- ber of minutes in 12 hours equals the factorial of a natural number (720 = 6!). An interactive applet allows one to “play” with the clock.

Published: July 2016

Infill walls provide durable and economical partitions that have relatively excellent thermal and sound insulation with high fire resistance. Monolithic infilled walls are provided within RC structures without being analyzed as a combination of concrete and brick elements, although in reality they act as a single unit during earthquakes. The performance of such structures during earthquakes has proved to be superior in comparison to bare frames in terms of stiffness, strength and energy dissipation. To know the dynamic characteristics of monolithic infill wall panels and masonry infill, modal, response spectrum and time history analyses have been carried out on a model and prototype of a 3D RC structure for a comparative study.
Pseudo-symmetry analysis to unravel the secrets of twins – a case study with four diverse examples
Authors: Stöger Berthold , Weil Matthias , Murugesan Sathiyamoorthy , Kirchner Karl
Published: July 2016

Four twins are interpreted by pseudo-symmetry analysis. The pincer complexes Co(PCP)X (X=Cl, Br) are order-disorder (OD) twins. The individuals are composed of one polytype with a maximum degree of order (MDO) with Pc symmetry, whereas at the composition plane is located a fragment of the second MDO polytype with Pbc21 symmetry. The twinning of the low-temperature (LT, 100 K) P21 phase of 2,3-dicyanohydroquinone dihydrate (DCHQ·H2O) can be explained by a symmetry reduction of index 2 from the high-temperature (HT, 250 K) Pn21
m phase. Propylammonium perchlorate (nPrNH3ClO4) features different kinds of twinning. On the one hand, transformation twinning is caused by a symmetry reduction of index 2 from the HT (150 K) Pbnm to the LT (100 K) P21/n phase. On the other hand, the crystals feature growth twinning by rotation about the [010] axis, where the nature of the twin interface remains unknown. The twinning of the Ccce Ba[H2TeO5] structure with pseudo-tetragonal metrics is explained by a part of the structure featuring higher P42/nmc symmetry. At the twin interface is probably located a fragment with the formal composition TeO3.

Published: July 2016

The spin Hamiltonian parameters and local structures are theoretically studied for Cu2+-doped alkaline earth lead zinc phosphate (RPPZ, R=Mg, Ca, Sr, and Ba) glasses based on the high-order perturbation calculations for a tetragonally elongated octahedral 3d9 cluster. The relative elongation ratios are found to be ρ≈3.2%, 4.4%, 4.6%, and 3.3% for R=Mg, Ca, Sr, and Ba, respectively, because of the Jahn-Teller effect. The whole decreasing crystal-field strength Dq and orbital reduction factor k from Mg to Sr are ascribed to the weakening electrostatic coulombic interactions and the increasing probability of productivity of nonbridge oxygen (and hence increasing Cu2+–O2− electron cloud admixtures) under PbO addition, respectively, with increasing alkali earth ionic radius. The anomalies (the largest Dq and the next highest k among the systems) for R=Ba are attributed to the cross linkage of this large cation in the network. The overall increasing order (Mg≤Ba<Ca<Sr) of ρ is largely due to the decreasing crystal-field strength Dq and hence the decreasing force constant of the Cu2+–O2− bonds. The present studies would be helpful to understand local structures and the influences on the optical properties of RPPZ glasses containing copper dopants.
