The use of multi-agent systems for task planning in Grid systems will solve two main problems - scalability and adaptability. The methods and techniques used today do not sufficiently provide solutions to these complex problems. Thus, the scientific task of improving the effectiveness of methods and tools for managing problem-oriented distributed computing in a cluster Grid system, integrated with traditional meta-planners and local resource managers of Grid nodes, corresponding to trends in the concept of scalability and adaptability.
Focusing of expansion waves

The flow field which results from an expansion wave entering a cavity, and the focusing effect which occurs was studied using both numerical and experimental methods. Previous research into cavity flows has looked at shock waves entering a cavity as well as shock wave focusing phenomenon; however no previous work on expansion wave cavity flows was found. The type of flow was analysed for different cavity geometries, different expansion wave pressure ratios and different expansion wave widths. The numerical work was done using the commercial CFD codes, Ansys Fluent and STAR CCM+. An inviscid solver was found to be sufficiently accurate to model the flow. The experimental work was performed using a unique shock tube with windows at the diaphragm and in the driver section. A number of sub-studies were done during the development of the shock tube. These included a short study on the use of different materials as a diaphragm in a shock tube in order to get the best possible expansion wave for the experiments. Hundred micron thick aluminium sheets were found to give the best burst as it responded well to scoring and once scored gave a consistent symmetrical burst. Another study was performed into the straightening of an initially curved expansion wave. This was done to try and improve the experimental results as a diaphragm will always have some curvature at burst resulting in an initially curved expansion wave. It was found that by curving the walls of a shock tube the leading edge of an expansion wave could be made to straighten faster, however this introduced additional undesirable two-dimensional waves behind the leading edge of the expansion which resulted in a simple straight walled shock tube being used in the experiments. The numerical and experimental work showed that a focus region forms when an expansion wave enters a cavity, and this region has very low fluid property values, especially temperature and pressure. The basic focus region can be described as a region of flow enclosed by compression or shock waves in which two dimensional expansion waves repeatedly reflect to create very low pressures and temperatures. The effect of an initially curved expansion wave was considered and it was found that the flow is significantly affected by the shape of the expansion. For a plane expansion wave a focus region develops in the driver section of the tube and collapses towards the end of the driver. For a curved expansion wave the focus region develops at the centre of the curvature. The pressure ratio over the expansion wave
Association of chronic inflammation with cardiovascular risk in chronic obstructive pulmonary disease—A cross‐sectional study

COPD is progressive lung disease with known higher cardiovascular (CV) risk, mainly attributed to smoking of cigarettes as the main etiological factor of disease. The aim of this study was to compare CV risk in patients with COPD to control groups of smokers and non‐COPD and to investigate the relation of lung function variables, COPD severity, and smoking with Systemic Coronary Risk Estimation (SCORE) risk calculation, arterial stiffness (AS) values, and biological systemic inflammatory markers.
Node Architectures for Next Generation ROADMs: A comparative study among emergent optical solutions

Reconfigurable optical add and drop multiplexers (ROADMs) are key components to increase the dynamicity and flexibility of optical networks. In its first generation, solely based on PLC and WSS-technology, ROADMs allowed service providers to automate some of its network operations, reducing the OPEX and improving the quality of service offered to the customer. However, the current solution is limited to several constrains such as direction, color and contention, and still demands truck rolls and manual reconfiguration depending on the desired operation. To address this limitation, new optical components are emerging and particularly two node architectures are being considered as most promising candidates: multicast switch with optical amplification array and dense low loss fiber optical cross-connect with MUX/DEMUX AWGs. This paper compares both solutions, and a third variation using fiber OXC in conjunction with WSS, from a CAPEX and OPEX perspective. It concludes that depending on the network scenario one solution is more suitable than the others and probably, in the next generation reality, different node architectures will be required in different portions of a same network.
Effects of Uneven Ground Surface on Human Balance

The effect of anteroposteriorly slanted ground surface on human posture control at fully flexed trunk postures was investigated in this study. Custom made wooden apparatus were used to simulate slanted ground surfaces, the slanted were set at -15, 0 and 15 degrees respectively. The flat ground condition was included in the study as a control. Fourteen healthy male subjects were asked to maintain in fully flexed trunk posture while standing on different ground surfaces. The segmental sway motion of C7, T12 and S1 spinal vertebrae in the anteroposterior (AP) and mediolateral (ML) directions were recorded. Results showed that when standing on an anteroposteriorly slanted ground surface and facing downhill (i.e. -15 degree condition) subjects consistently demonstrated the highest sway speeds and reported the highest subjective rating of instability. Therefore, we concluded that, when standing on an anteroposteriorly slanted ground surface in a fully flexed trunk posture facing downhill may result in much higher risk of falling in comparison to facing the opposite direction.
Distribution Drivers of the Alien Butterfly Geranium Bronze (Cacyreus marshalli) in an Alpine Protected Area and Indications for an Effective Management

Simple Summary Cacyreus marshalli is strictly dependent on its host plant (Pelargonium spp.), which is widely cultivated as an ornamental plant in mountain areas. An experiment demonstrated that the butterfly is able to develop on some wild geraniums, too, making mountain areas highly at risk for a potential expansion to natural habitats. We therefore decided to carry out research in a protected mountain area (Gran Paradiso National Park), focusing on the drivers which determine the distribution of C. marshalli using data provided by either an opportunistic approach or a rigorous survey protocol. The data collected via the planned survey were more informative than the opportunistic observations, which were few and narrow. We suggest investing more in citizen science projects and combining them with a designed protocol according to an integrated approach. We observed that C. marshalli distribution is strictly linked to host plant availability but is constrained by cold temperatures, although Pelargonium spp. are abundant. The temperature increase scenario showed an increase of butterfly abundance, but halving of the host plant population could drive the rate of infestation to return to what it was previously, excluding a countertrend in some high-altitude sites. It is therefore important to test management actions designed to control alien species before implementing them. Abstract Cacyreus marshalli is the only alien butterfly in Europe. It has recently spread in the Gran Paradiso National Park (GPNP), where it could potentially compete with native geranium-consuming butterflies. Our study aimed to (1) assess the main drivers of its distribution, (2) evaluate the potential species distribution in GPNP and (3) predict different scenarios to understand the impact of climate warming and the effect of possible mitigations. Considering different sampling designs (opportunistic and standardised) and different statistical approaches (MaxEnt and N-mixture models), we built up models predicting habitat suitability and egg abundance for the alien species, testing covariates as bioclimatic variables, food plant (Pelargonium spp.) distribution and land cover. A standardised approach resulted in more informative data collection due to the survey design adopted. Opportunistic data could be potentially informative but a major investment in citizen science projects would be needed. Both approaches showed that C. marshalli is associated with its host plant distribution and therefore confined in urban areas. Its expansion is controlled by cold temperatures which, even if the host plant is abundant, constrain the number of eggs. Rising temperatures could lead to an increase in the number of eggs laid, but the halving of Pelargonium spp. populations would mostly mitigate the trend, with a slight countertrend at high elevations.
Research methods for online research on disability

Nowadays, the proportion of people who make daily use of the internet is growing rapidly. The benefits from this use are numerous; communication, exchanges, studies, businesses, marketing, access to information and knowledge, research are all considerably benefited. The present paper discusses how research on disability can be facilitated through the application of online research methods. It is concluded that it is important to adapt conventional research methods, both qualitative and quantitative, for online use, since it is an extremely time- and cost-effective way to reach the sample that is representative of the general population and to collect and analyze the data. The most important contribution of online research is that it provides the opportunity to recruit participants -people with disabilities- from anywhere in the world and gain an international perspective for the study. The appropriateness of using a range of different types of online communication, such as Collaborative Virtual Environments, for the purpose of qualitative research is also discussed and their potential of conveying non-verbal information is assessed.
Emotional and psychological well-being in Indonesian adolescents: Translation and construct validation of the Stirling Children’s Well-being Scale in a college student sample

Abstract The present study aimed to culturally adapt the Stirling Children’s Well-being Scale (SCWBS) for use in Indonesia with college student and to assess their psychometric properties in this population. This study investigated the dimensions, particularly the nature and number, of the Indonesian version of the SCWBS. Three hundred seventy-five Indonesian college students were recruited through WhatsApp. Exploratory and confirmatory factor analyses were performed on two subsamples, which were randomly divided using IBM SPSS, and the reliability of the SCWBS was assessed using Cronbach’s alpha. An exploratory factor analysis extracted two dimensions, which explained 58.24% of the total variance. A confirmatory factor analysis was performed on the two-factor measurement model of the scale, along with one second-order factor. These were found to have good model fit. The final 10-item SCWBS had high reliability and acceptable construct validity. Therefore, the scale was found to have adequate psychometric properties and to be applicable in research and practice. For further refinement, the Indonesian version of the SCWBS should be tested in a wider age range and in various subgroups, for example, to analyze socioeconomic status. Furthermore, it is necessary to assess other construct validity, such as criterion validity.

The linkage between mercury-caused neuro- and genotoxicity via the inhibition of DNA repair machinery: fish brain model

Heavy metals in model conditions as well as industrial pollution launch disturbances in neural cells of different animals and human beings. The neurotoxicity of mercury, which is one of the most toxic heavy metals, has been studied for several decades. However, its low doses chronic exposure effects for neural tissue cells are still poorly understood. Therefore, the basic molecular mechanisms of mercury should be clarified. The purpose of our research is to clarify the mechanism of mercury genotoxicity, the role of the DNA repair protein apurinic/apyrimidinic endonuclease 1 (APE1) in neural tissue cells, and the response to inorganic mercury-induced neurotoxicity. In our model, we used juvenile rainbow trout exposed to mercury chloride with a range of doses 9‑36 µg/L for 60 days to study the cytotoxicity of chronic exposure. We detected the reactive oxygen species (ROS) production as an index of oxidative stress and APE1 as a marker of cellular DNA damage response in a neural cell. The ROS level was measured by using the fluorometric method based on 2',7'-dichlorofluorescein diacetate reaction. The analyses of markers of the DNA repair (APE1) and apoptosis (B cell lymphoma-2 anti-apoptotic protein – Bcl-2) were carried out with western blotting. The mercury chloride chronic exposure induced statistically significant upregulation of the ROS production in the fish brain. Contrary, the mercury low doses stimulated the downregulation of APE1 expression in the brain tissue. Furthermore, mercury chronic exposure inhibited the expression of Bcl-2 in the animals treated with 18 and 36 µg/L mercury chloride. The harmful effect of mercury could be promoted by oxidative stress generation. The downregulation of APE1 expression could lead to a lack of DNA damage response efficacy and initiate the decline in neural cell functioning. Obtained data on the APE1 expression have shown that the neurotoxic effect of mercury could be mediated, at least partially, by the decline in cellular DNA damage response in the brain. The evaluation of decrease in DNA repair response via detection of the APE1 expression can be a prospective tool to reveal the deleterious effects of toxicants in terms of their neuro- and genotoxicity.
Resisting and reifying meaning in everyday life: Using relational dialectics theory to understand the meaning of heterosexual dating

Heterosexual women have intersecting identities that are privileged (i.e., sexuality) and marginalized (i.e., gender), suggesting a complicated site to examine power in the process of dating where meaning has become taken-for-granted over time. In this study, we utilized relational dialectics theory’s (RDT’s) corresponding method, contrapuntal analysis, to examine a group that holds fluctuating societal power in the context of heterosexuality and dating. Findings from the responses of women (n = 104) revealed two discourses that competed to illuminate the meaning of heterosexual dating from the perspective of women: the dominant Discourse that Dating is Romantic and Necessary (DDRN) and the marginal Discourse that Dating is Restrictive and Unrealistic (DDRU). These discourses interplayed through contractive practices (i.e., disqualification and naturalization), diachronic separation, synchronic interplay (i.e., entertaining, countering, and negating), and dialogic transformation (i.e., discursive hybridization and aesthetic moment), illuminating a discursive struggle that both reified and resisted the DDRN.
Does Sustainability Matter to Fashion Consumers? Clustering Fashion Consumers and Their Purchasing Behavior in Spain

Abstract Using choice-based conjoint analysis, this research explores consumer behavior for sustainable fashion in Spain. We confronted consumers through an online survey with a real marketplace situation in which they had to make trade-offs between different attributes and where the importance of the price factor was explicitly considered. Specifically, the information available for consumers on clothing hangtags – price, country of origin, material composition, and (with/without) fair-trade label – was used to study consumer preferences for sustainable fashion products. Furthermore, we examined how consumers ponder the five dimensions of sustainable fashion – functionality, authenticity, exclusivity, localism and equity. Based on a sample of 1,063 respondents, the results indicate that price is still the critical purchasing driver for the average consumer. 31.9% of the sample always chose the lowest price-tag independently of the other attributes. Combining the conjoint results, the attitude towards the five dimensions of slow fashion, and demographics, we identified four clusters of consumers: Sustainability Rejecters, Sustainability Neutrals, Sustainability Believers, and Sustainability Enthusiasts. Ninety-two consumers, 8.65% of the sample, appear to buy sustainable fashion regularly. This endorses and significantly adds to the literature on sustainable fashion consumer behavior in a flourishing market and to the attitude-behavior gap research.

Optical characterization of materials

In our daily life, the role of quality is steadily increasing: we are interested in the quality of our food, we want our car to be robust and – in general – we wish that all the things we use in our everyday life should be as durable as possible. In the future, coping with these challenges and delivering products of a documented high quality will be essential for companies in order to becomemarket leaders. Improving measurement systems and methods for quality assessment facilitate this development and will be part of the goods issuing department of most future production sites. Within a few years, such methods will also be incorporated in mobile devices, so that the customer can determine the quality of his goods of interest directly inside the store. The Karlsruhe Center for Material Signatures (KCM), which is a collaboration of different institutes of the Karlsruhe Institute of Technology (KIT) and the Fraunhofer Institute of Optronics, System Technologies and Image Exploitation (IOSB), followed the described trend by founding the international conference on Optical Characterization of Materials (OCM), which has attracted many participants. The articles of this special issue of Technisches Messen (tm) represent revised versions of selected contributions of the OCM conference held in March 2015 at the Fraunhofer IOSB in Karlsruhe. The authors of the eight contributions make use of very different spectral bands (e. g., UV, VIS, NIR) and they employ several innovative analysis methods (e. g., SVM, PCA, random forests). Their supposed applications spread over a wide range and are partly complementary to each other (food,mining, recycling). This special issue provides the reader with numerous ideas of how to perform a characterization of materials and shows him the chances and limitations of the proposed methods. The article of Sebastian Bauer and Fernando Puente León investigates the light emission of mineral samples
Assessing the Speciation of Lutjanus campechanus and Lutjanus purpureus through Otolith Shape and Genetic Analyses

Based on their morphological and genetic similarity, several studies have proposed that Lutjanus campechanus and Lutjanus purpureus are the same species, but there is no confirmed consensus yet. A population-based study concerning otolith shape and genetic analyses was used to evaluate if L. campechanus and L. purpureus are the same species. Samples were collected from populations in the southwestern Gulf of Mexico and the Venezuelan Caribbean. Otolith shape was evaluated by traditional and outline-based geometric morphometrics. Genetic characterization was performed by sequencing the mtDNA control region and intron 8 of the nuclear gene FASD2. The otolith shape analysis did not indicate differences between species. A nested PERMANOVA identified differences in otolith shape for the nested population factor (fishing area) in morphometrics and shape indexes (p = 0.001) and otolith contour (WLT4 anterior zone, p = 0.005 and WLT4 posterodorsal zone, p = 0.002). An AMOVA found the genetic variation between geographic regions to be 10%, while intrapopulation variation was 90%. Network analysis identified an important connection between haplotypes from different regions. A phylogenetic analysis identified a monophyletic group formed by L. campechanus and L. purpureus, suggesting insufficient evolutionary distances between them. Both otolith shape and molecular analyses identified differences, not between the L. campechanus and L. purpureus species, but among their populations, suggesting that western Atlantic red snappers are experiencing a speciation process.
