Automorphisms of decompositions
Authors: Hannan Tim , Harding John 
Published: July 2016

Abstract
In [HARDING, J.: Decompositions in quantum logic, Trans. Amer. Math. Soc. 348 (1996), 1839–1862] the author showed that the direct product decompositions of many different types of structures, such as sets, groups, vector spaces, topological spaces, and relational structures, naturally form orthomodular posets. When applied to the direct product decompositions of a Hilbert space, this construction yields the familiar orthomodular lattice of closed subspaces of the Hilbert space.
In this note we consider orthomodular posets Fact X of decompositions of a finite set X. We consider the structure of these orthomodular posets, such as their size, shape, connectedness, states, and begin a study of their automorphism groups in the context of the natural map Γ from the group of permutations of X to the automorphism group of FACT
X.
We show Γ is an embedding except when |X| is prime or 4, and completely describe the situation when |X| has two or fewer prime factors, when |X| = 23 and when |X| = 33. The bulk of our effort lies in a series of combinatorial arguments to show Γ is an isomorphism when |X| = 27. We conjecture that this is the case whenever |X| has sufficiently many prime factors of sufficient size, and hope that our arguments here might be adapted to the general case.
Dissolution, gelation, functionalization, and material preparation of chitin using ionic liquids
Authors: Kadokawa Jun-ichi 
Published: July 2016

AbstractIn this article, a review of the research endeavors concerning ionic liquids, that have been used as media for dissolution, gelation, functionalization, and material preparation of chitin, is presented. Although chitin has been identified to show difficulty in solubility and processability, leading to mostly an unutilized organic resource, some ionic liquids have been found to dissolve chitin in certain concentrations. For example, the author found that an ionic liquid, 1-allyl-3-methylimidazolium bromide (AMIMBr), dissolved chitin in concentrations up to 4.8 wt% and formed ion gels at higher contents of chitin. Cellulose/chitin binary ion gel and film were also obtained from the individually prepared polysaccharide solutions with ionic liquids. The binary ion gel was applied as a novel electrolyte for an electric double layer capacitor. Acetylation of chitin using acetic anhydride in AMIMBr gave chitin acetates with high degrees of substitution. The modification technique in the AMIMBr solvent was applied to the synthesis of a chitin macroinitiator for atom transfer radical polymerization (ATRP). Grafting of styrene by ATRP from the resulting macroinitiator was conducted to give chitin–graft–polystyrene. Self-assembled chitin nanofibers were fabricated in a methanol dispersion obtained by regeneration from the chitin ion gel with AMIMBr using methanol, which formed a film by subjecting the dispersion to filtration. Co-regeneration from the chitin ion gel coexisting poly(vinyl alcohol) (PVA) gave a self-assembled chitin nanofiber/PVA composite film. The self-assembled chitin nanofibers have also been used as a reinforcing agent for cellulose derivatives to produce composite films.
Seed Mass and Seed Yield of Six Roses (Rosa L., Rosaceae Adans.) from Central Russia (Republic of Mordovia)
Authors: Khapugin Anatoliy A. 
Published: July 2016

AbstractGenusRosaL. is one of most critical taxa within European flora. Majority works is devoted to phylogeny, taxonomy and nomenclature of roses. Investigations of morphology and ecology of roses are still relatively few in number. The aim of this study was to evaluate seed mass and seed yield of six rose species (Rosa cinnamomea,R. spinosissima,R. rugosa,R. rubiginosa,R. glaucaandR. canina) from populations in Central Russia (Republic of Mordovia). As a result of the study, it was revealed thatRosa rugosahas maximal num-ber of seeds per rosehip among all investigated roses. Roses from sectionCaninaeare characterized by large number of achenes per rosehip too. In contrast, among all investigated species,Rosa cinnamomeahave most minimal seed yield. Origin ofRosa spinosissimapopulation in Ruzaevka district (Republic of Mordovia, Central Russia) was proposed as uncertain according to number of seeds per rosehip. At first time, the seed mass ofRosa cinnamomea,R. glaucaandR. rubiginosawas revealed.
Combining ability of phenological traits and seed yield in spring rapeseed genotypes
Authors: Rameeh Valiollah 
Published: July 2016

Abstract
Six parents and their 15 F2 diallel progenies, totally 21 genotypes, were evaluated for genetic parameters of quantitative characteristics. The traits of interest were growing degree days (GDDs) from sowing to the flowering (DDF), to end of flowering (DDE), flowering period (DFP), to maturity (DDM) and seed yield (SY). Significant mean squares of general combining ability (GCA) was exhibited for DDF, DDE, DFP, DDM and seed yield indicating significant differences of GCA effects of parents for these traits. Significant mean squares of specific combining ability (SCA) for all the traits exhibited the importance of non additive genetic effects for the traits. Significant ratio of MS(GCA)/MS(SCA) and high narrow sense heritability estimates for DDF, DDE, DDM indicating the prime importance of additive genetic effects for controlling these traits. DFP was also less heritable than the other phonological traits, so the efficiency of selection for this trait will be low. All of the combinations with significant negative SCA effects for DDM had at least one parent with significant negative GCA effect for this trait. PF7045/91 with significant positive GCA effect of SY, was best combiner for improving SY. Significant positive correlation between DDM and each of two traits including DDF and DDE, indicating these traits can be used as indirect selection criteria for improving DDM.

Published: July 2016

Abstract
This study analysed the effects of different treatments on breaking dormancy and germination of bitter vetch (Vicia ervilia L.) freshly harvested seeds for seeding immediately. Partial scarified seeds (30 seconds with sandpaper) were subjected to different treatments including: GA3 (250, 500 and 750 ppm), KNO3 (0.1, 0.2 and 0.3% w/v), cold stratification (2, 4 and 6 days), sulfuric acid (25, 50 and 75 seconds), hot water (90°C; for 2.5 and 5 minutes), hydropriming via seed soaking in distilled water (4 and 8 hours) and mechanical scarification. Among the mentioned treatments, cold stratification for 6 days had a best effect on germination related parameters final germination percentage, mean germination time and vigour indexthan the other periods. In contrast to scarification with acid and hot water, mechanical scarification improved germination parameters but this effect was lower than the cold stratification. The results suggest that bitter vetch seed has both physical and physiological dormancy.
Priming treatments for improvement of germination and emergence of cotton seeds at low temperature
Authors: Çokkizgin Hatice , Bölek Yüksel 
Published: July 2016

AbstractEarly sowing in cotton is important for obtaining a high and qualiy yield. Since cotton prefers high temperatures to have a good stand establisment, this work is important to determine better performing genotypes or to promote germination and emergence at low temperatures (<20°C). This research aimed to increase seed germination rate and seed vigour under cold stress conditions. Two cotton genotypes belonging toG. hirsutumL. species (Aydin-110 and Paymaster-2379) were primed with PEG-6000 (200, 300, 400 g/L), KNO3(2, 3, 4%), KH2PO4(0.3, 0.4, 0.5 M), NaCl (2, 3, 4%) or Mannitol (2, 4, 6%) to determine the best priming medium and its best amount. After priming, seeds were germinated in germination cabin at cold (18°C) and warm (30°C) temperatures and some characteristics (germination rates, radicle length, hypocotyl length and seedling length) were analyzed. Priming with KNO3(4% or 2%) was found to result in the highest germination rates in both cotton genotypes. The seeds of the genotypes were also primed with 5-aminolevulinic acid (ALA) (1, 10, 25 mg/L), gibberellic acid (GA3) (100, 250, 500 μM), methyl jasmonate (MeJA) (1, 3, 5 μM), acetylsalicylic acid (ASA) (1, 10, 100 μM) or kinetin (1, 5, 10 mg/L) added to KNO3(4%) medium to choose the most effective plant growth regulator (PGR) application and its dose. PGRs were observed to have reverse effects on germination rate. Finally, emergence test was conducted with KNO3(4%) and KNO3(2%) using metabolic chill test, and some traits (radicle length, radicle weight, hypocotyl length, hypocotyl weight, seedling length, seedling fresh weight and seedling dry weight) were examined. Our results suggested that priming with KNO3(2%) might be an effecient way to have vigourous cotton plants under the cold stress.
Boundary Element Method Applied to Added Mass Coefficient Calculation of the Skewed Marine Propellers
Authors: Yari Ehsan , Ghassemi Hassan 
Published: July 2016

Abstract
The paper mainly aims to study computation of added mass coefficients for marine propellers. A three-dimensional boundary element method (BEM) is developed to predict the propeller added mass and moment of inertia coefficients. Actually, only few experimental data sets are available as the validation reference. Here the method is validated with experimental measurements of the B-series marine propeller. The behavior of the added mass coefficients predicted based on variation of geometric and flow parameters of the propeller is calculated and analyzed. BEM is more accurate in obtaining added mass coefficients than other fast numerical methods. All added mass coefficients are nondimensionalized by fluid density, propeller diameter, and rotational velocity. The obtained results reveal that the diameter, expanded area ratio, and thickness have dominant influence on the increase of the added mass coefficients.
Method of Sum of Power Losses as a Way for Determining the ki Coefficients of Energy Losses in Hydraulic Motor
Authors: Maczyszyn A. 
Published: July 2016

Abstract
This paper shows application of the method of sum of power losses to determining energy losses which occur in hydraulic rotary motor in situation when not all laboratory data are at one’s disposal or when no use is made of data contained in catalogue charts. The method makes it possible to determine the coefficients, ki, of energy losses occurring in the motor. The method of sum of power losses is based on the approach proposed by Z. Paszota, in the papers [3 ÷ 9]. It consists in adding power flow of energy losses occurring in the motor to power flow output and comparing the sum to the power flow input. Application of the method is exemplified by using a A6VM hydraulic motor.
A Method for Reliability Assessment of Structural Components of Aircraft and Sea-Going Ships with Taking into Account a Given Failure Generation Model
Authors: Tomaszek Henryk , Zieja Mariusz , Ważny Mariusz 
Published: July 2016

Abstract
This paper presents a metod for reliability assessment of structural components on the basis of diagnostic parameters recorded during operation of aircraft and sea going ships. It was assumed that a potential failure may simultaneously concerns surface wear process and fracture of an arbitrary structural component. In order to develop a reliability assessment model some elements of random walk theory were applied. This work covers surface wear density functions of a component. In the case of surface wear the model is based on a difference equation from which, after transformation, a Fokker-Planck partial differential equation was obtained. By solving the equation component’s surface wear density function is achieved.
In the second part of the work a generalization of the model was made by introducing to it probability of disastrous fracture of a component. As a result, a generalized Fokkera-Planck’s equation was obtained. By making use of the equation, was obtained a relationship for assessment of reliability of a structural component in case when failure occurs due to surface wear with taking into account possible fracture of the component. In the end a numerical example which shows practical application of the developed method, is attached.
Does formal education at all levels cause economic growth? Evidence from Greece
Authors: Pegkas Panagiotis , Tsamadias Constantinos 
Published: July 2016

Abstract
This study empirically investigates the link between the levels of formal education and economic growth in Greece during the period 1960-2009. The paper applies the Lucas approach (1988) and employs cointegration, error-correction models and estimates the effect of each educational level on economic growth. The empirical analysis reveals that there is a long-run relation between educational levels and gross domestic product. The overall results show that secondary and higher education has had a statistically significant positive impact on growth, while primary has not contributed to economic growth. The findings also suggest that there is evidence of unidirectional long-run causality running from primary education to growth, bidirectional long-run causality between secondary and growth, long-run and short-run causality running from higher education to economic growth.
Measuring Financial Distress and Predicting Corporate Bankruptcy: An Index Approach
Authors: Liao Qunfeng , Mehdian Seyed 
Published: July 2016

Abstract
In this paper, we follow Anderson et al. (2009) and suggest a simple approach to employ a set of financial ratios as inputs to estimate an aggregate bankruptcy index (ABI). This index is a within sample measure, ranges between 0 and 1, and ranks the firms on the basis of their relative financial distress. ABI can be used to predict the propensity of financial failure and corporate bankruptcy. For the purpose of comparison and assessment of the robustness of this index, we estimate Z-score by multivariate discriminant analysis, using the same set of financial ratios to compare the predictive accuracy of two approaches.
We find that, to some extent, ABI can predict the bankruptcy of the firms more accurately than Z-score. The empirical results of the paper suggest that ABI has relatively robust predictive power and, therefore, can be applied together with other, based on parametric and non-parametric models to predict corporate bankruptcy.
Determinants of Loan Quality: Lessons from Greek Cooperative Banks
Authors: Makri Vasiliki , Papadatos Konstantinos 
Published: July 2016

Abstract
The article focuses on the credit risk of cooperative banks in Greece. The main objective is to define which factors are responsible for variations in loan quality during the period 2003-2014. Loan quality is measured by Loan Loss Reserves Ratio (LLR) and dynamic regression techniques are implemented for the econometric estimations. The outlined results suggest that the macroeconomic environment (i.e. public debt, local unemployment, economic activity and inflation) and the accounting ratios (i.e. past loan quality and profitability) seem to be the explanatory variables of problem loans.
Business Intelligence Security
Authors: Tofan Dragoş Ovidiu 
Published: July 2016

Abstract
Excess information characteristic to the current environment leads to the need for a change of the organizations’ perspective and strategy not only through the raw data processing, but also in terms of existing applications generating new information. The overwhelming evolution of digital technologies and web changes led to the adoption of new and adapted internal policies and the emergence of regulations at level of governments or different social organisms. Information security risks arising from the current dynamics demand fast solutions linked to hardware, software and also to education of human resources. Business Intelligence (BI) solutions have their specific evolution in order to bring their contribution to ensure the protection of data through specific components (Big Data, cloud, analytics). The current trend of development of BI applications on mobile devices brings with it a number of shortcomings related to information security and require additional protective measure regarding flows, specific processing and data storage.

Brain Gain am Beispiel Österreich
Authors: Aschbacher Christine , Gejguš Mirko , Sablik Jozef 
Published: July 2016

Abstract
BrainGain is a common trend within the last ten years in Europe and all-over the world. Managers, key players and scientists are allowed to choose wherever they want to work in the world. As there is a lack of qualified individuals for companies and universities, BrainGain has become a necessity, and mostly – the higher educated individuals are moving away according to a better offer elsewhere in the world. Therefore, a lot of expats are moving around with their families. Many times, the lack of integration at the current place, country or city, is the critical success factor for staying or leaving. Furthermore, if the family does not feel happy in the current location, then the manager or scientist will move away or return home and the investment will be lost.
Moreover, many students have received a good education in a state university, however afterwards they have not secured a satisfactory job in the country where they have studied, therefore they are moving away to utilise their know-how. Measures to retain the know-how include a common placement and a welcome-culture in the country, and also exchanges on an international level.
A case story, involving the use of maltitol, a sugar alcohol, as a cutting agent in amphetamine and cocaine powders
Authors: Reitzel Lotte Ask , Holm Niels Bjerre , Linnet Kristian , Müller Irene Breum 
Published: July 2016

Abstract
In a criminal case involving cutting and resale of amphetamine and cocaine in the Copenhagen area of Denmark, maltitol was used as a cutting agent. The analysis of maltitol in seizures of pure diluents as well as in amphetamine and cocaine powders was carried out using reversed-phase high performance liquid chromatography (HPLC) with high-resolution (HR) mass spectrometric detection. Maltitol was identified in four out of nine amphetamine samples and in five out of six cocaine samples from the case in question. The use of maltitol as a cutting agent was considered by the police as a specific marker of the particular criminal group under investigation. To support or reject this hypothesis, cocaine and amphetamine samples from a four month period after the involved persons had been arrested were evaluated, also as part of the police investigation. None of these samples contained maltitol. The work described covers the part of the case involving the department of forensic chemistry, and not the whole police investigation, but everything was done within the frames given by the police. To the best of our knowledge, this is the first report of a disaccharide polyol being used as a cutting agent for illicit drugs.
The Role of Respiratory Infection in Sudden Infant Death Syndrome (SIDS)
Authors: Mage David T. , Latorre Maria L. , Jenik Alejandro G. , Donner E. Maria 
Published: July 2016

Abstract

Introduction: The Sudden Infant Death Syndrome (SIDS) is not likely to be explained by a currently measureable presence in all cases and absence in controls, as otherwise it would have been solved already. Indeed, any proposed physiological model for SIDS causation must explain the constant mathematical and statistical properties of SIDS age and gender. We have shown previously that SIDS are characterized by a common 4-parameter lognormal age distribution sparing neonatal infants, by a nominal 50% male excess, and by a higher rate in winter than summer. We test now whether SIDS is closely related to a fulminating prodromal Acute Respiratory Infection (ARI) by a common increasing rate with the infants increasing Live Birth Order (LBO), all remaining the same, independent of the change in preferred sleeping positions of the infants, prone or supine.

Methods: We use U.S. published infant mortality data from wonder.cdc.gov and other countries (Colombia, U.K., Europe, Australasia) to make comparisons between the two causes of death (ARI and SIDS) to evaluate how closely ARI resembles the characteristics of SIDS.

Results: Gender: SIDS male excess 50%, ARI male excess 50%; Ages: SIDS 90% post-neonatal, ARI 96% post-neonatal; Seasonality: SIDS and ARI are higher in winter than summer; Live birth order: SIDS and ARI rates increase with increasing LBO with similar mathematical relationship.

Conclusion: Our results show that all SIDS are very likely relatable to a single cause tied to a fulminating prodromal ARI in a physiologically anemic infant who is genetically (X-link recessive) susceptible to cerebral anoxia. An alternative cause of all SIDS death by a collection of subsets of different causes, such as brainstem-related respiratory abnormalities and cardiac QT abnormalities, is not supported because they cannot all have the same age-gender-seasonal-familial-distributions of SIDS, required by Cramér’s Theorem.
A Few New 2+1-Dimensional Nonlinear Dynamics and the Representation of Riemann Curvature Tensors
Authors: Wang Yan , Zhang Yufeng , Zhang Xiangzhi 
Published: July 2016

Abstract
We first introduced a linear stationary equation with a quadratic operator in ∂
x
and ∂
y
, then a linear evolution equation is given by N-order polynomials of eigenfunctions. As applications, by taking N=2, we derived a (2+1)-dimensional generalized linear heat equation with two constant parameters associative with a symmetric space. When taking N=3, a pair of generalized Kadomtsev-Petviashvili equations with the same eigenvalues with the case of N=2 are generated. Similarly, a second-order flow associative with a homogeneous space is derived from the integrability condition of the two linear equations, which is a (2+1)-dimensional hyperbolic equation. When N=3, the third second flow associative with the homogeneous space is generated, which is a pair of new generalized Kadomtsev-Petviashvili equations. Finally, as an application of a Hermitian symmetric space, we established a pair of spectral problems to obtain a new (2+1)-dimensional generalized Schrödinger equation, which is expressed by the Riemann curvature tensors.
