Towards emergence phenomenon in business process management
Authors: Koryl Maciej , Mazur Damian 
Published: June 2017

Abstract
A standard solution regarding business process management automation in enterprises is the use of workflow management systems working by the Rule-Based Reasoning approach. In such systems, the process model which is designed entirely before the implementation has to meet all needs deriving from business activity of the organization. In practice, it means that great limitations arise in process control abilities, especially in the dynamic business environment. Therefore, new kinds of workflow systems may help which typically work in more agile way e.g. following the Case-Based Reasoning approach. The paper shows another possible solution – the use of emergence theory which indicates among other conditions required to fulfill stimulation of the system (for example the business environment) to run grass-roots processes that lead to arising of new more sophisticated organizing forms. The paper also points the using opportunity of such techniques as the processing of complex events to fulfill key conditions pointed by the emergence theory.

Abstract
Recent studies have confirmed that hyperhomocysteinemia is associated with gastrointestinal diseases; however, the direct effect of homocysteine on gastrointestinal reactivity still remains unknown. The aim of this study was to demonstrate how homocysteine may affect nitric oxide mediated duodenal relaxation and whether cholinergic receptors and K+ channels take part in stimulating motility, as well as to explore whether oxidative stress is associated with homocysteine-mediated effects. Experiments were carried out on male rats, body mass 250-300 g. Two groups of animals were treated by i.p. application of saline and D,L-Hcy (0.6 μmol/g bm). After 2h of incubation, the duodenal segments were prepared for biochemical analysis and contractile response measurements in an organ bath with Tyrode’s solution. Effects of TEA (10 mmol/L) and L-NAME (30 μmol/L) on duodenal contractility in the presence of D,L-Hcy (0.6 μmol/g bm) were investigated. Elevated homocysteine levels seem to be of crucial importance for the deterioration of contractility through nitric oxide mediated relaxation, and, in part, by activation of K+ channels. Hcy showed direct promuscarinic effects, since 30 min pretreatment of rat duodenum significantly enhanced the contractile effect of increasing concentrations of ACh (10−9-10−2 mol/L). Catalase activity, superoxide dismutase, glutathione peroxidase and the total antioxidant system were reduced while the thiobarbituric acid-reactive substances level was elevated. Our data showed a consistent profile of gastrointestinal injury elicited by sulfur-containing amino acid-homocysteine. This could contribute to explain, at least in part, the mechanisms involved in human gastrointestinal diseases associated to hyperhomocysteinemia.

Published: June 2017

Abstract
Gender identification of fish species is carried out mainly by examining external morphological characteristics, which in general, it is very complex and not always a reliable approach. Electrophoresis of plasma proteins can be used as an alternative and useful molecular tool for a more precise sex determination. The presence of female specific proteins in the plasma is a starting point for the application of this technique. In this study, reducing discontinuous sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) was applied to analyze plasma proteins of male and female koi carp (Cyprinus carpio haematopterus). Image analyses of electrophoregrams with resolved plasma proteins by SDS-PAGE showed that it is an appropriate technique to discriminate male from female samples. It is based on the presence of apolipoprotein B-100 which can be used as a suitable marker. Further amino acid characterization of apolipoprotein B-100 confirmed that it is a specific protein for female individuals.

Summary
Fear of needles can significantly limit professional and social functioning of a person, and is highly prevalent in general population (4%).
The aim of our study was to reveal risk factors that are associated with fear of needles among healthy university students of medicine and pharmacy.
The study was of a cross-sectional type. In total, 301 students of medicine or pharmacy (82% female and 18% male) attending from 1st to 5th year of study were surveyed at the Faculty of Medical Sciences, University of Kragujevac, Serbia. The students were surveyed using a questionnaires (scales) for assessing the fear of needless, a visual analog scale for self-assessment intensity of the fear of needless, and a general questionnaire with questions about socio-demographic characteristics of the participants. Using a score on the scales as out-come variables, multiple regressions were employed to reveal factors that may influence the fear of needles.
Average values of Blood/Injection Fear Scale, Injection Phobia Scale-Anxiety and Medical Avoidance Survey scores were 7.89 ± 9.48, 4.46 ± 5.18 and 89.95 ± 12.73, respectively. The following factors affected significantly the score of the scales: course of study, chronic disease in the family, fear of a dentist, smell of the room phobia, sound phobia, score on the Beck’s anxiety scale and fear of a situation when medical staff give an injection. The presence of chronic disease in the family was a protective factor, while the other six factors were contributing to the fear of needles.
Fear of needles is more prevalent among the students of pharmacy than among the students of medicine. It is less frequent among students with chronic disease in their family, while fear of dentist, smell of the room phobia, sound phobia, general anxiety and fear from the situation when medical staff give an injection are all factors that predispose students of medicine or pharmacy to develop fear of needles.

Abstract
Defense components such as chitinases (EC 3.2.1.14) are crucial for plants to cope diseases. Despite of that the pattern and activities of these enzymes in agronomically important Triticale is unexplored. This work is aimed to study chitinase activities in the leaves of plants of early developmental stages in two diploids (Aegilops tauschii Coss., Triticum monococcum L.), four tetraploids (Ae. cylindrical Host, Ae. triuncialis L., T. araraticum Jakubyz, T. dicoccum Schrank) and two hexaploids (T. aestivum L., T. spelta L.). The leaves were subjected to quantitative and qualitative activity assays using synthetic 4-methylumbelliferyl-β-D-N,N´,N´´-triacetylchitotrioside and glycolchitin as substrates, respectively. Our results showed that the activities of chitinases with specificity towards short oligomers were variable and genotype dependent. The enzyme activities in the tetra- and hexaploid genotypes were significantly higher than in diplod counterparts. In the gel detection assays were revealed up to four fractions (~20, 30, 42 and 95 kDa) of proteins with the chitinase activity towards long chain polymers. The isoform of ~30 kDa was identified in all analyzed genotypes. Among the seven acidic and three basic chitinase fractions identified, three acidic (ChiA, ChiB, ChiC) and two (ChiH, ChiI) fractions were present in all genotypes. None of the isoforms can be assigned as specific with respect to ploidy.

Published: June 2017

Abstract
Miscanthus × giganteus is considered as a perspective energy crop for biomass production in Ukraine where its commercial production has been observed. The herbivorous pest may pose a risk of yield reduction when an energy crop is growing on monoculture. The herbivorous diversity, species composition and potential damage associated with growing M. × giganteus were studied on seven experimental sites at three locations in Ukraine. The different life stages of herbivorous insects from seven orders representing thirteen families were found on M. × giganteus during the herbivorous survey and most of the insects had a pest status. Research indicated that crop was an alternate host for key cereal pest the Hessian fly Mayetiola destructor (Say) (Diptera: Cecidomyiidae). A comparative analysis of the biodiversity of herbivorous insects across research locations was done using statistical analysis. It was found that site location played a significant role in the level of biodiversity and an increase in the insect’s herbivores diversity was associated with the type of researched lands. The massive scale commercial use of M. × giganteus should take into account a responsible consideration of the benefits and risks associated with that crop in order to protect agroecosystems.

Progress in this production branch may depend on the dairy production support which is given after relevant types of actions are undertaken. The objective of the research was to determine changes in the level of welfare of production animals, evaluation of practice in dairy cows breeding in the province of Ropczyce and Sędziszów. Breeding documentation and control protocols of the Coordinated Veterinary Inspection Program were applied pursuant to the resolution (1) of the Minister of Agriculture and Rural Development of 28 June 2010 on minimal conditions of maintaining farm animal species. 10 production herds of dairy cows (n-240) and heifers (n=101) which produce ≥ 10200 kilo of milk per lactation were used to achieve this objective. Dairy production was observed during individual visits in farms. Surveys were carried out with farm employees with the use of properly prepared veterinary control protocols of the Coordinated Veterinary Inspection Program. Control results were obtained based on the respondents' opinion from controlling institutions, such as: The Agency for Restructuring and Modernization of Agriculture, Regional Veterinary Office and similar certified bodies.

Published: June 2017

Abstract
A non-isothermal kinetic analysis of kaolinite dehydroxylation was carried out using thermogravimetric analysis on powder samples with heating rates from 1 to 30 °C・min-1 in a dynamic air atmosphere. The mechanism of the reaction, values of overall activation energy and pre-exponential factor were determined from a series of thermogravimetric experiments by the Coats- Redfern method. The results show that the dehydroxylation of kaolinite is controlled by the rate of the third-order reaction (F3) with the mean values of overall activation energy (EA) 255 kJ・mol-1 and pre-exponential factor (A) 25.56 × 1014 s-1.
The revision and extension of the RMS ring for time delay systems
Authors: Pekař L. , Prokop R. 
Published: June 2017

AbstractThis paper is aimed at reviewing the ring of retarded quasipolynomial meromorphic functions (RMS) that was recently introduced as a convenient control design tool for linear, time-invariant time delay systems (TDS). It has been found by the authors that the original definition does not constitute a ring and has some essential deficiencies, and hence it could not be used for an algebraic control design without a thorough reformulation which i.a. extends the usability to neutral TDS and to those with distributed delays. This contribution summarizes the original definition of RMSsimply highlights its deficiencies via examples, and suggests a possible new extended definition. Hence, the new ring of quasipolynomial meromorphic functions RQMis established to avoid confusion. The paper also investigates and introduces selected algebraic properties supported by some illustrative examples and concisely outlines its use in controller design.
Towards automation of measurement processes of surface water parameters by a remote-controlled catamaran
Authors: Wiora J. , Kozyra A. , Wiora A. 
Published: June 2017

AbstractThis paper describes a way of determining selected water parameters using a prototype of a remote-controlled catamaran. The remote controlling allows to steer the boat and to manage the measurement process from the shore. It is possible to monitor the water parameters online as well as to store them and analyze them afterwards. The measured parameters are determined mainly using potentiometric methods and include several ion concentrations. The system is orientated towards monitoring breeding ponds or other similar surface waters. The mechanical construction of the catamaran, its electronic circuits and implemented software are described in detail in the paper. Conclusions obtained from preliminary tests are also included. The described construction allows analysts to perform simple and inexpensive remote measurements or assessments of water quality and reduces the time of such analysis in comparison to traditional sampling.
The effect of sampling interval on the predictions of an asperity contact model of two-process surfaces
Authors: Pawlus P. , Reizer R. , Wieczorowski M. , Żelasko W. 
Published: June 2017

AbstractContact of random machined two-process steel textures with a smooth, flat steel surface is discussed in this paper. Two-process surfaces were machined by vapour blasting followed by lapping. An elastic-plastic contact model was applied, assuming distributed radius of asperities. Calculation procedures allowed the mean surface separation, contact pressure, and area fraction to be computed as functions of sampling intervals. Parameters characterizing the summits important in contact mechanics were calculated for different sampling intervals. Plasticity index of two-process textures was calculated using the modified procedure. It was found that the influence of sampling interval on normal contact depended on the rough surface ability to plastic deformation. The use of a traditional method of calculation overestimated the plasticity index. Peaks from plateau surface region governed contact characteristics of two-process surfaces.

Published: June 2017

AbstractIn this article we present a novel linguistically driven evaluation method and apply it to the main approaches of Machine Translation (Rule-based, Phrase-based, Neural) to gain insights into their strengths and weaknesses in much more detail than provided by current evaluation schemes. Translating between two languages requires substantial modelling of knowledge about the two languages, about translation, and about the world. Using English-German IT-domain translation as a case-study, we also enhance the Phrase-based system by exploiting parallel treebanks for syntax-aware phrase extraction and by interfacing with Linked Open Data (LOD) for extracting named entity translations in a post decoding framework.
Partition Based Perturbation for Privacy Preserving Distributed Data Mining
Authors: Antony Sheela M. , Vijayalakshmi K. 
Published: June 2017

Abstract
Data mining on vertically or horizontally partitioned dataset has the overhead of protecting the private data. Perturbation is a technique that protects the revealing of data. This paper proposes a perturbation and anonymization technique that is performed on the vertically partitioned data. A third-party coordinator is used to partition the data recursively in various parties. The parties perturb the data by finding the mean, when the specified threshold level is reached. The perturbation maintains the statistical relationship among attributes.

Published: June 2017

Abstract
The study presents a numerical analysis of the arched footbridge designed in two variants, made of steel and aluminium. The first part presents the criteria for evaluation of the comfort of using the footbridges. The study examined the footbridge with arched design with span in the axis of 24 m and width of 1.4 m. Arch geometry was made as a part of the circle with radius of r = 20 m cut off with a chord with length equal to the calculation length of the girders. The model of the analysed footbridge was subjected to the dynamic effect of wind and the pedestrian traffic with variable flexibility. The analyses used Robot Structural Analysis software.

Published: June 2017

Abstract
The analysis of influence of factors that depend on construction characteristics of the vibrosieves with circular vibrations on screening efficiency is presented in this paper. The dependence of the screening efficiency on the aperture size, length and inclination of the screen, as well as on vibration amplitude, is considered. Based on obtained results, one can see that the screening efficiency increases with vibration amplitude and the screen length increase. Further, increases of the screen inclination and aperture size are causing an initial increase of the screening efficiency, which is later decreasing.

Authors: Roldugin Pavel V. 
Published: June 2017

Abstract
The paper is concerned with the subsets I ⊂ {0, ..., d – 1} for which gcd(n – m, d) ≠ 1 for any n, m ∈ I. Such subsets are called sets of nontrivial differences. Let d > 1 and d
1 be the least prime divisor of d. We prove that the largest cardinality of a set of nontrivial differences is d/d
1. Sets of nontrivial differences in which not all differences of elements are multiples of the same prime factor d are called nonelementary. Let t be the number of prime factors of d. We show that there are no nonelementary sets for t ⩽ 2. It is shown that a minimal nonelementary set may have arbitrary order in the interval

Four-point key-hole side-edge-notched bending (4KHSENB) strength of medium-density fibreboard
Authors: Yoshihara Hiroshi , Maruta Makoto 
Published: June 2017

AbstractFour-point key-hole side-edge-notched bending (4KHSENB) tests of medium-density fibreboard (MDF), a quasi-isotropic material, were conducted. The experimental results were analysed via data reduction methods, including the elementary beam theory (EBT), the point stress criterion (PSC), the average stress criterion (ASC) and linear elastic fracture mechanics (LEFM), which are applicable to MDF specimens. The PSC and ASC approaches accurately predicted the relationship between the nominal critical stress at the onset of nonlinearity and the notch length. The same is true for predicting the relationship between the nominal bending strength and the notch length.

Published: June 2017

Abstract
Performance trends in elite butterfly swimmers are well known, but less information is available regarding master butterfly swimmers. We investigated trends in participation, performance and sex differences in 9,606 female and 13,250 male butterfly race times classified into five-year master groups, from 25-29 to 90-94 years, competing in the FINA World Masters Championships between 1986 and 2014. Trends in participation were analyzed using linear regression analysis. Trends in performance changes were investigated using mixed-effects regression analyses with sex, distance and a calendar year as fixed variables. We also considered interaction effects between sex and distance. Participation increased in master swimmers older than ~30-40 years. The men-to-women ratio remained unchanged across calendar years and master groups, but was lower in 200 m compared to 50 m and 100 m. Men were faster than women from 25-29 to 85-89 years (p < 0.05), although not for 90-94 years. Sex and distance showed a significant interaction in all master groups from 25-29 to 90-94 years for 200m (p < 0.05). For 50 m and 100 m, a significant sex × distance interaction was observed from 25-29 to 75-79 years (p < 0.05), but not in the older groups. In 50 m, women reduced the sex difference in master groups 30-34 to 60-64 years (p < 0.05). In 100 m, women decreased the gap to men in master groups 35-39 to 55-59 years (p < 0.05). In 200 m, the sex difference was reduced in master groups 30-34 to 40-44 years (p < 0.05). In summary, women and men improved performance at all distances, women were not slower compared to men in the master group 90-94 years; moreover, women reduced the gap to men between ~30 and ~60 years, although not in younger or older master groups.
