Abstract
The flux-weighted average cross sections of the 89Y(γ,xn; x=1–4)89−x
Y reactions and the isomeric yield ratios of the 87m,gY, 86m,gY, and 85m,gY radionuclides produced in these reactions with the bremsstrahlung end-point energies of 65, 70 and 75 MeV have been determined by an activation and off-line γ-ray spectrometric technique using the 100 MeV electron linac in Pohang Accelerator Laboratory, Korea. The theoretical 89Y(γ,xn; x=1–4)89−x
Y reactioncross sections for mono-energetic photonshave been calculated using the computer code TALYS 1.6. Then the flux-weighted theoretical values were obtaind to compare with the present data. The flux-weighted experimental and theoretical 89Y(γ,xn; x=1–4)89−x
Y reaction cross sections increase very fast from the threshold values to a certain bremsstrahlung energy, wherethe other reaction channels open up. Thereafter it remains constant a while and then slowly decreases with the increase of cross sections for other reactions. Similarly, the isomeric yield ratios of 87m,gY,86m,gY and 85m,gY in the 89Y(γ,xn; x=2–4)89−x
Y reactions from the present work and literature data show an increasing trend from their respective threshold values to a certain bremsstrahlung energy. After a certain point ofenergy, the isomeric yield ratios increase slowly with the bremsstrahlung energy. These observations indicate the role of excitation energy and its partitioning in different reaction channels.
Residential Property Price Indices on Small Property Markets
Authors: Kokot Sebastian 
Published: April 2017

AbstractThere are many reasons for the fact that reliable property indices are difficult to calculate. Even though, in theory, there are several acknowledged methods of their determination, this task poses problems of various nature in practice. These problems grow when the data sets are limited, which is the case on small property markets where the number of transactions are low. The paper is an attempt to compute property price indices on the basis of a statistically smoothed series of average unit prices of residential properties sold on a small market, exemplified by the county of Łobez. Additionally, the paper discusses the problems that have emerged over the course of the study, as well as the obtained results, as viewed in the context of the general situation on the property market.

Published: April 2017

Abstract
The research discussed in the article focuses on public space in urban areas and revitalization activities carried out by local governments. The goals of the paper are to identify the conditions and opportunities for the development of public space by local governments of Bulgaria and Poland, to find regularities (similarities and differences) and to assess the actions taken. The specific objective is to illustrate the process of planning and managing selected large revitalization investments in urban public spaces in Bulgaria and Poland. The research methods used comprise the analysis of literature, including official documents and acts of law and case studies.
The paper analyzes the conditions and manifestations of activities taken by local governments regarding investment in public space (development and revitalization of public space programs and investing in real estate) in Bulgaria and Poland, using examples from selected cities. The authors selected two comparable urban areas: Varna in Bulgaria and Poznań in Poland, chosen intentionally due to the similarity of the two post-socialist bloc countries and the availability of information. Bulgarian and Polish state law and various acts of local law were analyzed. The experimental part of the publication introduces case studies of investments in the revitalization of real estate in public space managed by the local governments. It shows examples of projects which are relevant to the development of the cities under study.
Maple Trees – Host Plants for Some Phytoseiid Mites
Authors: Kabíček J. 
Published: April 2017

AbstractPhytoseiid mite communities on Acer pseudoplatanus, A. platanoides, and A. campestre were monitored in 2013-2014. Totally 3657 specimens of phytoseiid mites belonging to seven species (Euseius finlandicus, Neoseiulella aceri, N. tuberculata, Typhlodromus (Typhlodromus) pyri, Paraseiulus soleiger, P. triporus, and Phytoseius echinus) were found on the examined maple leaves. N. aceri, the most common species, was dominant and frequently present on the leaves of both A. platanoides and A. campestre. The leaves of A. pseudoplatanus were favourable habitats for both E. finlandicus and N. tuberculata. Thus, maple trees may serve as suitable host plants for some native phytoseiid mites, particularly N. aceri and E. finlandicus.

Published: April 2017

Abstract
The aim of the study was to evaluate the effect of one-week quantitative feed restriction (in days 8-14 of age) on histological characteristics of musculus pectoralis major in broiler chickens during the fattening period. Cockerels of Ross 308 (1215 chicken) were divided into 3 groups: ad libitum fed (AL; 3 × 135), restricted 80% of AL (R80; 3 × 135), and with limited feed intake 65% of AL (R65; 3 × 135). Eight cockerels per group were slaughtered in weekly intervals from day 14 of age till the end of experiment at 35 days to determine changes in the muscle fibre characteristics. The number of muscle fibres in pectoralis major decreased (P ≤ 0.001) with increasing age. Fibre cross sectional area was s ignificantly (P ≤ 0.027) affected by the interaction of group and age. At the end of feed restriction at 14 days all groups had similar fibre area (519-539 μm2), the differences between groups were observed at 35 days of age with the largest fibre area in R65 chickens (2296 μm2), while R80 did not differ from AL (1728 μm2 and 1667 μm2). There was no effect of feeding regime on giant muscle fibre incidence.
A time warping approach to multiple sequence alignment
Authors: Arribas-Gil Ana , Matias Catherine 
Published: April 2017

AbstractWe propose an approach for multiple sequence alignment (MSA) derived from the dynamic time warping viewpoint and recent techniques of curve synchronization developed in the context of functional data analysis. Starting from pairwise alignments of all the sequences (viewed as paths in a certain space), we construct a median path that represents the MSA we are looking for. We establish a proof of concept that our method could be an interesting ingredient to include into refined MSA techniques. We present a simple synthetic experiment as well as the study of a benchmark dataset, together with comparisons with 2 widely used MSA softwares.

Published: April 2017

AbstractWisteria floribundais a deciduous liana species widely distributed in Japan. It is essential to evaluate the clonal structure of this species because high clonal ability enables lianas to make dense colonies after canopy gaps occur. Therefore, we developed 10 microsatellite markers forW. floribundafrom genomic shotgun sequences available in the publicly available database to study clonal structure and life history strategy of this species. The number of alleles per locus ranged from 7 to 16, with an average of 10.2. The observed and expected heterozygosity ranged from 0.483 to 0.926 and from 0.642 to 0.916, with averages of 0.769 and 0.800, respectively. These findings will contribute to the understanding of ecological roles and management of this species.
The Relationship of Spike Stall and Hub Corner Separation in Axial Compressor
Authors: Jiang Bin , Shi Xiangtong , Zheng Qun , Zhu Qingfang , Chen Zhongliang , Tian Zhitao 
Published: April 2017

AbstractThe onset of spike stall induced by the interaction of hub corner separation flow with the tip leakage flow is investigated in detail by numerical method in this paper. The time resolved results indicate that the remarkable radial secondary flow from hub to tip near the trailing edge is formed when the compressor approaching rotating stall. The radial secondary flow is unstable and cross-passages propagates, which flows in and away out of the tip region periodically. The disturbance caused by radial secondary flow will influence the tip leakage flow directly by reforming the vortexes in blade tip region. A secondary vortex which comes from the radial migration of corner separation and is induced by the tip leakage vortex appears in the tip region. The simulation result demonstrates that the generation of the secondary vortex is an important symbol of blockage growth in the tip region at the stall inception phase. The disturbance produced by secondary vortex is an incentive of the leading edge overflow and the intensity of secondary vortex could be used as a criterion of rotating stall before leading edge spillage.

Abstract
A novel modeling method for aircraft engine using nonlinear autoregressive exogenous (NARX) models based on wavelet neural networks is proposed. The identification principle and process based on wavelet neural networks are studied, and the modeling scheme based on NARX is proposed. Then, the time series data sets from three types of aircraft engines are utilized to build the corresponding NARX models, and these NARX models are validated by the simulation. The results show that all the best NARX models can capture the original aircraft engine’s dynamic characteristic well with the high accuracy. For every type of engine, the relative identification errors of its best NARX model and the component level model are no more than 3.5 % and most of them are within 1 %.

➢ The increasing prevalence of knee osteoarthritis in an aging and active population necessitates the development of therapies designed to relieve symptoms, to delay the need for total joint replacement, and to potentially stimulate chondrocyte growth.➢ Growth factor therapies such as platelet-rich plasma have been studied extensively for knee osteoarthritis, with the recent publication of clinical studies. Although the majority of studies conclude that platelet-rich plasma has the potential to provide symptomatic relief on a short-term basis, to our knowledge, long-term data are lacking.➢ Growing interest in stem cell therapy for knee osteoarthritis has led to various studies utilizing mesenchymal stem cells from adipose, bone marrow, or peripheral blood sources. Although studies have shown excellent early clinical results, the ability to improve collection rates of mesenchymal stem cells and methods to direct mesenchymal stem cell differentiation to chondrocytes and to promote chondrogenesis remains a focus for future research.➢ There are still many questions about platelet-rich plasma and its effectiveness for knee osteoarthritis. Differences in preparation technique make effective evaluation and comparison difficult.➢ Bone marrow mesenchymal stem cells currently remain the only stem cell product that appears to be approved by the U.S. Food and Drug Administration (FDA) without any potential questions about use. Further clinical studies are still necessary to fully understand their role.

Published: April 2017

Students enrolled in university courses often lack knowledge of potential jobs and career paths they can take, which can inhibit their ability to plan, job seek and make decisions about their careers, and negatively impact on their ability to gain employment. To address this problem we developed and piloted a tailored, career-focused interactive online learning tool for public health and exercise science students, based on constructs of Savickas’ (2005) theory of career construction. This paper reports a mixed-methods study to understand student experiences of using that tool, and their perception of how well it prepared them for career planning. Twenty-two second-year students completed an online survey using both qualitative and quantitative methods to assess the perceived feasibility and acceptability of the interactive online learning tool. Descriptive (for quantitative data) and inductive content analyses (for qualitative data) were performed. Most students (86%) indicated that they would use the tool again. All students reported that the tool was user-friendly, engaging and informative and provided them with jobs that matched their personal and work-related skills and strengths. Qualitative data reflected these findings and identified seven key themes, including: value, career exploration, design, and tailoring, with themes partly reflecting components of Savicka’s theory. The tailored, career-focused interactive online learning tool was perceived to be a feasible and effective strategy to support university students in their career planning and job seeking behaviours prior to graduation. These findings can be used to inform and refine the development of career-focussed tools for students undertaking other University courses.
An economic-efficiency analysis of water conservancy investment in Heilongjiang Province based on projection pursuit clustering and DEA models

Published: April 2017

Abstract
Water conservancy investment affects economic development. To scientifically analyze its economic efficiency, this paper employs a projection pursuit clustering model based on the real-coded accelerated genetic algorithm to reduce the number of output index systems for each year, and the relative economic efficiency is obtained for 13 cities in Heilongjiang Province during the period 2007–2012 using a data envelopment analysis (DEA) model. The spatial distribution regulation is described based on the average efficiency derived for the period 2007–2012. Finally, the output values are optimized for ineffective cities under the optimization principle according to the 2012 values. The results show that the output index system is different for each year. Most cities exhibit comprehensive effectiveness, and the development of water conservancy is generally good. The spatial distribution regulation of economic efficiency tends to be high in the south and low in the north because it is related to local economic development and water policies. To achieve comprehensive effectiveness, the output indices need to be adjusted. This study assists with the promotion of efficient development plans for water conservancy systems and the economic efficiency of water conservancy investment in Heilongjiang Province.
