The paper presents a fast and efficient method for the detection and characterisation of delamination in photovoltaic (PV) modules by using active infrared thermography approach. A discrete part of PV module was irradiated by step heating and its thermal image sequence was used to detect and analyse delamination. Different types of heating source for thermal excitation for this application have been studied. An electro-thermal model was developed to simulate the active thermography approach for the characterisation of delamination in PV module by equivalent resistance-capacitance (RC) network using a circuit simulator. This simulation approach was used to estimate the extent of delamination in the module and to determine the optimum parameters for the characterisation of delamination. Different applications based on front and backsides of heating the module were also proposed in this paper. The proposed method has the potential to be employed for the quality check of PV modules during inline production as well as for the predictive maintenance of outdoor PV plants.

WOS: 000379136700007 The aim of this study was to evaluate the bond strength of a universal adhesive system to dentin prepared with SiC paper or an Er, Cr:YSGG laser using different bonding strategies (etch-and-rinse versus self-etch mode). Ninety-six extracted caries-free, sound human molars were used. The teeth were longitudinally sectioned in the mesiodistal direction and were wet polished with 600-grit SiC paper to obtain a standardized flat dentin surface. All prepared teeth were randomly divided into two groups, according to the surface preparation method: GroupI: an erbium, chromium: yttrium, scandium, gallium, garnet laser; Group II: silicon carbide paper[SiC] (n = 48). Each group was then assigned into three subgroups according to the universal adhesive's (Single Bond Universal) bonding strategies: (a) etch-and-rinse mode with phosphoric acid, (b) etch-and-rinse mode with a laser, (c) self-etch mode (n = 16). For surface preparation, the Er, Cr: YSGG laser was used at 3 W, 30 Hz with 140 mu s pulse duration for 25 s. For etching mode, the laser was used at 1.5 W (60% air, 70% water). Cylinders of composite were fabricated on the bonding area and shear bond strength was determined using a universal testing machine. Failure modes were evaluated using a stereomicroscope. The data were analyzed using two-way ANOVA followed by the Bonferroni test (p < 0.05). Bonding strategies showed statistically significant differences in both the SiC-and laser-prepared groups (p < 0.05). Universal adhesive used in etch-and-rinse mode with acid showed significantly higher bond strength values than in self-etch mode (p < 0.05). The bond strength values did not differ according to the surface preparation method (p > 0.05). Irrespective of preparation method, using universal adhesive in etch-and-rinse mode with acid might improve dentin bond strength. Laser preparation did not affect the bond strength of the universal adhesive tested.

© 2015 EDGAR G. DAYLIGHT. In the popular imagination, the relevance of Turing's theoretical ideas to people producing actual machines was significant and appreciated by everybody involved in computing from the moment he published his 1936 paper ‘On Computable Numbers’. Careful historians are aware that this popular conception is deeply misleading. We know from previous work by Campbell-Kelly, Aspray, Akera, Olley, Priestley, Daylight, Mounier-Kuhn, Haigh, and others that several computing pioneers, including Aiken, Eckert, Mauchly, and Zuse, did not depend on (let alone were they aware of) Turing's 1936 universal-machine concept. Furthermore, it is not clear whether any substance in von Neumann's celebrated 1945 ‘First Draft Report on the EDVAC’ is influenced in any identifiable way by Turing's work. This raises the questions: (i) When does Turing enter the field? (ii) Why did the Association for Computing Machinery (ACM) honor Turing by associating his name to ACM's most prestigious award, the Turing Award? Previous authors have been rather vague about these questions, suggesting some date between 1950 and the early 1960s as the point at which Turing is retroactively integrated into the foundations of computing and associating him in some way with the movement to develop something that people call computer science. In this paper, based on detailed examination of hitherto overlooked primary sources, attempts are made to reconstruct networks of scholars and ideas prevalent in the 1950s, and to identify a specific group of (Formula presented.) actors interested in theorizing about computations in computers and attracted to the idea of language as a frame in which to understand computation. By going back to Turing's 1936 paper and, more importantly, to re-cast versions of Turing's work published during the 1950s (Rosenbloom, Kleene, Markov), I identify the factors that made this group of scholars particularly interested in Turing's work and provided the original vector by which Turing became to be appreciated in retrospect as the father of computer science. ispartof: HISTORY AND PHILOSOPHY OF LOGIC vol:36 issue:3 pages:205-228 ispartof: location:BELGIUM, Ghent Univ, Ghent status: published

It is well-known that the primal quadratic growth condition of the classical augmented Lagrangian around a local minimizer can be obtained under the second-order sufficient optimality condition. In this paper, we show that those conditions are indeed equivalent. Moreover, we prove that the primal quadratic growth condition of the sharp augmented Lagrangian around a local minimizer is in fact equivalent to the weak second-order sufficient optimality condition. In addition, we present some secondary results involving the sharp augmented Lagrangian. Fil: Fernández Ferreyra, Damián Roberto. Consejo Nacional de Investigaciones Científicas y Técnicas.

In this paper the relation between religion and income is investigated using a micro-dataset for the Netherlands. Religiosity is measured by religious membership and by participation. Instead of estimating separately a religion and an income equation, joint regression is preferred since this generally yields more efficient estimates. Following the single equation approach, both religious measures are found to decrease significantly income and income is found to affect negatively religion. However, these cross-effects get insignificant once the equations are simultaneously estimated. In contrast, the effects of socio-economic characteristics on religion and income hardly differ between both approaches.This discussion paper has resulted in a publication in Applied Economics.

This paper addresses the process of event handling and rescheduling in manufacturing practice. Firms are confronted with many diverse events, such as new or changed orders, machine breakdowns, and material shortages. These events influence the feasibility and optimality of schedules, and thus induce rescheduling. In many manufacturing firms, schedules are created by several human planners. Coordination between them is needed to respond to events adequately. In this paper, the practice of coordination during event handling is analysed by an extensive case study. The study shows that human planners spend much time in communicating events and in negotiating rescheduling solutions. Because many events demand a quick response, the possibilities for coordination are restricted by time constraints. The paper proposes a procedure to structure the event handling process. This procedure helps a scheduler to select an appropriate response to an event by evaluating its influence on schedule feasibility and the time available for coordination and rescheduling. The use of the procedure in the case company has led to improved rescheduling performance through a reduction of scheduler interactions and increasing coordination efficiency. The procedure contributes to traditional planning frameworks and paradigms, and supports the conscious selection and use of rescheduling methods in manufacturing practice.

Innovative organisations need creative employees who generate new ideas for product or process innovation. This paper presents a conceptual framework for the effect of personal, social-organisational and physical factors on employee creativity. Based on this framework, an instrument to analyse the extent to which the work environment enhances creativity is developed. This instrument was applied to a sample of 409 employees and support was found for the hypothesis that a creative work environment enhances creative performance. This paper illustrates how the instrument can be used in companies to select and implement improvements. STATEMENT OF RELEVANCE: The ergonomics discipline addresses the work environment mainly for improving health and safety and sometimes productivity and quality. This paper opens a new area for ergonomics: designing work environments for enhancing employee creativity in order to strengthen an organisation's capability for product and process innovation and, consequently, its competitiveness.

Advances in production planning and control in recent decades have focused on increasing the sophistication of the planning function. For good reasons, these advances have led to the centralisation of the planning function in production. However, the sophistication of the planning function should be in balance with monitoring and control of the plan. Monitoring and control are by their nature decentralised, beginning on the shop floor, and, therefore, the desire for greater sophistication in monitoring and control leads to renewed interest in decentralised and localised approaches. This paper demonstrates the possibility of using intelligent products for decentralised monitoring and control. Intelligent products are aware of their local context and can negotiate with local manufacturing resources. As such, local solutions to problems can be proposed directly when problems occur. With the advancement of the 'Internet of Things', such a scenario is likely to become feasible in the near future. The paper demonstrates the viability of such an approach through a simulation study, in which robustness is included as an additional measure of performance. The results of the simulations are encouraging.

Introduction: Pulmonary route is one of the preferred routes for the administration of therapeutically active agents for systemic as well as localized delivery. Chronic obstructive pulmonary disease (COPD), bronchial asthma, pneumonia, pulmonary hypertension, bronchiolitis, lung cancer, and tuberculosis are the major chronic diseases associated with the pulmonary system. Knowledge about the affecting factors, namely, the etiology, pathophysiology, and the various barriers (mechanical, chemical, immunological, and behavioral) in pulmonary drug delivery is essential to develop an effective drug delivery system. Formulation strategies and mechanisms of particle deposition in the lungs also play an important role in designing a suitable delivery system.Areas covered: In the present paper, various drug delivery strategies, viz. nanoparticles, microparticles, liposomes, powders, and microemulsions have been discussed systematically, from a patent perspective.Expert opinion: Patent publications on formulation strategies have been instrumental in the evolution of new techniques and technologies for safe and effective treatment of pulmonary diseases. New delivery systems are required to be simple/reproducible/scalable/cost-effective scale for manufacturing ability and should be safe/effective/stable/controllable for meeting quality and regulatory compliance.

The practice of taking hand-written notes in lectures has been rediscovered recently because of several studies on its learning efficacy in the mainstream media. Students are enjoined to ditch their laptops and return to pen and paper. Such arguments presuppose that notes are taken in order to be revisited after the lecture. Learning is seen to happen only after the event. We argue instead that student’s note-taking is an educational practice worthy in itself as a way to relate to the live event of the lecture. We adopt a phenomenological approach inspired by Vilém Flusser’s phenomenology of gestures, which assumes that a gesture like note-taking is always an event of thinking with media in which a certain freedom is expressed. But Flusser’s description of note-taking focusses on the individual note-taker. What about students’ note-taking in a lecture hall as a collective gesture? Nietzsche considered note-taking ‘mechanical,’ as if students were automatons who mindlessly transcribed a verbal flow, while Benjamin considered it an inaesthetic gesture: at best, boring; at worst, ‘painful to watch.’ In contrast, we argue that the educational potentiality of note-taking—or better, note-making—can be grasped only if we account for its mediaticity (as writing that displaces the voice), together with but distinct from its political potentiality as a collective mediality (as a ‘means without end’). Note-taking enables us to see how collective thinking emerges in the lecture, a kind of thinking that belongs neither to the lecturer nor the student, but emerges in the relation of attention established between the lecturer, students and their object of thought.

This paper presents an exploratory study on the knowledge and importance of integrating Lean Education in curricula from the Academy perspective. The study was based on the analysis of participants' outcomes of workshops settled in international conferences. These workshops were used to promote Lean Education as a fundamental content and competency to be taught to the new professionals, independently of their future activity. Having in their DNA Lean content and competency, professionals will be thinkers adopting whole system-thinking, a sustainable conscious and ethical behaviour prepared to face Fourth industrial revolution demands. The authors believe that Lean Education provides such competencies to the new professionals and have been settling and operationalized such workshops in different contexts, involving more than 100 participants (mainly, academics) with teaching responsibilities in training the future workforce. Workshops outcomes were obtained from participants' active discussions and through a satisfaction assessment questionnaire filled by all participants at the end of the workshop. Results show that Lean Education is valuable by academics (more than 50% of the participants gave a high score to the practicality, value, and timeliness of the workshop contents). Nevertheless, a small percentage (12%) knows what Lean Education is or teaches Lean in the classes (10%)., This work has been supported by Fundacao para a Ciencia e Tecnologia (FCT) within the Project Scope: UID/CEC/00319/2019.

PEKEL, AHMET YAVUZ/0000-0001-9488-5599 WOS:000547109700001 The taste of food is an essential characteristic for cats and has been shown to affect food selection. However, understanding of food selection by cats using taste characteristics is far from complete. Therefore, the aim of the present review was to summarize the current knowledge on food preference and the role of taste on this selection in domestic cats. Appetite regulation is one of the determinants of palatability in cats and involves a highly complex interplay between hypothalamus, adipose tissue, and digestive tract. However, knowledge on this interplay is scarce in cats. When evaluating different foods for cats, behavioural responses such as facial expressions involving the movements and positions of ears, tongue, and head can provide increased insight into the effectiveness of formulating a more palatable diet. This paper also reviews food additives currently used in industry for enhancing the palatability of cat foods. In summary, a better understanding of the factors that affect the food preference in cats is essential to produce high-quality foods because cats will not eat a food with a flavour they dislike even though it is complete and nutritionally balanced.

Background: Schizophrenia spectrum disorders (SSD) are mental diseases caused by a combination of genetic susceptibility and a number of environmental factors. Among these factors, the role of traumatic events suffered in childhood, as well as that of substance use, have been of particular research interest. Objectives: To conduct a systematic review to clarify whether there is an interaction between childhood trauma and substance use related to the diagnosis or symptoms of SSD. It was also the objective of this review to collate the associations that may exist between the three variables of the study (trauma, substance use and psychosis). Methods: We conducted a systematic search resulting in 240 articles. We considered all of the original articles that explored childhood trauma and substance use in patients suffering from SSD. Results: Twenty-three articles were selected for this review. Several of the reviewed papers found associations between childhood trauma and substance use with SSD, as well as interactions between trauma and drug use on SSD. Conclusions: The results suggest that childhood trauma and substance usemay be present at the basis of psychosis. This double hit on the pathogenesis could have clinical implications, since each of these impacts could be considered a window of opportunity for the primary prevention of SSD.

Introduction: the importance of biomarkers for pharmaceutical drug development and clinical diagnostics is more significant than ever in the current shift toward personalized medicine. Biomarkers have taken a central position either as companion markers to support drug development and patient selection, or as indicators aiming to detect the earliest perturbations indicative of disease, minimizing therapeutic intervention or even enabling disease reversal. Protein biomarkers are of particular interest given their central role in biochemical pathways. Hence, capabilities to analyze multiple protein biomarkers in one assay are highly interesting for biomedical research. Areas covered: We here review multiple methods that are suitable for robust, high throughput, standardized, and affordable analysis of protein biomarkers in a multiplex format. We describe innovative developments in immunoassays, the vanguard of methods in clinical laboratories, and mass spectrometry, increasingly implemented for protein biomarker analysis. Moreover, emerging techniques are discussed with potentially improved protein capture, separation, and detection that will further boost multiplex analyses. Expert commentary: the development of clinically applied multiplex protein biomarker assays is essential as multi-protein signatures provide more comprehensive information about biological systems than single biomarkers, leading to improved insights in mechanisms of disease, diagnostics, and the effect of personalized medicine., European cooperation in science and technology - COST actionEuropean Cooperation in Science and Technology (COST) [CA16113], This paper was funded by the European cooperation in science and technology -COST action No. CA16113 - CliniMARK: `good biomarker practice' to increase the number of clinically validated biomarkers.

This paper reflects on multisensorial and multimodal processes by considering spatial design differently through three case studies in Canada and Belgium that involved persons with visual impairments. Our research provokes alternative ways of ‘seeing’ and ‘being’ in the world and we assert that the normative ways that designers think, act, and design for/with people who have disabilities can be shifted when considering ableism and techné together. Our studies and methods differ from other design processes and methods, in that we situate design within an understanding of ableism and techné, where we encourage designers to reflect upon their ability biases in order to break assumptions about the abilities and disabilities of users and/or codesigners. Through exploring, observing and creating, nuanced examinations into ability and techné are revealed that support an intimate bond and an empathic response towards shaping the designers’ understanding of participants embodied and practical knowledge. Our case study research expands the ways of knowing and doing in codesign through ableism and techné with people who are visually impaired, to create inspiring and meaningful designs through multisensorial processes that are inclusive of ‘seeing’ in order to spatialise differently.

This paper reports on a three-year research project aimed at examining experiences of being a teacher in a context of school reform and adverse times. A mixed-method research design was devised, including a national survey, semi-structured interviews, focus groups and a professional development programme. Findings suggest that teachers face old and new demands in a context of school reform and adverse times along with the worsening of their working conditions, the deterioration of their socio-economic status and the lack of career prospects. Some of them try to survive; others resist feelings of giving up by becoming more resilient and resisting. Professional values, a sense of professionalism and identity, along with the relational and emotional dimensions of teaching, and, in some cases, school culture and leadership, explain the ways in which some teachers became more resilient and resistant than others., This work was supported by the Fundacao para a Ciencia e a Tecnologia (National Foundation for Science and Technology) [PTDC/CPE-CED/112164/2009]., Portuguese national funds through the FCT (Foundation for Science and Technology) within the framework of the CIEC (Research Center for Child Studies of the University of Minho) project under the reference UID/CED/00317/2019

WOS: 000470591700001, In the present paper, a theoretically study of the non-resonant laser field effect on the optical response, such as nonlinear optical rectification (NOR), second (SHG) and third harmonic generation (THG) coefficients in double finite oscillator potential (DFO) quantum wells is performed in the framework of the effective mass approximation. The obtained results reveal that, energy states and optical response is significantly affected by the non-resonant intense laser field (ILF) intensity and symmetry of the structure. Also it was found that the laser field is more effective on the optical response in the DFO potential when the asymmetric character of the confinement potential is strong. Thus, the NOR, SHG and THG coefficients with designated values can be obtained by using a properly adjusted ILF intensity and symmetry parameter of confinement potential.

Athletes' energy distribution over a race (e.g. pacing behaviour) varies across different sports. Swimming is a head-to-head sport with unique characteristics, such as propulsion through water, a multitude of swimming stroke types and lane-based racing. The aim of this paper was to review the existing literature on pacing behaviour in swimming. According to PRISMA guidelines, 279 articles were extracted using the PubMed and Web of Science databases. After the exclusion process was conducted, 16 studies remained. The findings of these studies indicate that pacing behaviour is influenced by the race distance and stroke type. Pacing behaviours in swimming and time-trial sports share numerous common characteristics. This commonality can most likely be attributed to the lane-based racing set-up. The low efficiency of swimming resulting from propulsion through the water induces a rapid accumulation of blood lactate, prompting a change in swimmers' biomechanical characteristics, with the goal of minimising changes in velocity throughout the race. Although the literature on youth swimmers is scarce, youth swimmers demonstrate more variable pacing profiles and have more difficulty in selecting the most beneficial energy distribution.

Nesovic, Emilija/0000-0003-3600-0486 WOS: 000376031600006 In Minkowski space-time, timelike generalized Mannheim curves are studied by Akyigit and et al in [1]. In that paper, the authors take the Mannheim mate alpha* of the timelike curve a as a timelike curve in Minkowski space-time E-1(4). In this statement, the plane spanned by {B-1*, B-2*} becomes a spacelike plane. Thus the other possible cases such as timelike and null for the plane spanned by {B-1*, B-2*} is not considered. In this paper, by taking consideration of all possible causal characters of the plane spanned by{B-1*, B-2*}, we give the necessary and sufficient conditions for timelike curves ME to be generalized timelike Mannheim curves in terms of their curvature functions. Also, the related examples are given.

Real-time operational predictions of the major ocean basins which resolve the ocean mesoscale at mid-latitudes have become established in more than a dozen countries over the last 15 years. These predictions depend on the global ocean observing system (particularly satellite altimeters and the Argo profiling float system), high performance computers and sophisticated ocean models and data assimilation systems. They support an expanding range of information services for operations at sea, weather forecasts and protection of the environment. GODAE Oceanview (GOV) assists the groups developing these predictions. This paper provides an introduction to GOV and the papers in this special issue.

Warehouse operations are vital for the success of a supply chain. This paper explores fit among warehouse management structure and the context in which the warehouse operates as an important driver of warehouse performance. Warehouse management structure has been operationalised as the extensiveness by which warehouse operations are planned and controlled, and the complexity of the decision rules used for optimisation of the operations. Warehouse performance is measured using data envelopment analysis (DEA). Hypotheses are developed and tested in a survey study among 111 distribution warehouses in the Netherlands and Belgium. Our results show that indeed warehouse management structure should be adapted to context. In order to obtain high warehouse performance more complex warehouse tasks require more and more complex decision rules, and warehouses with more unpredictable demand require fewer tactical plans. These results can help warehouse managers to structure their warehouse management contingent on the context in which the warehouse operates.

E-commerce companies often use manual order-picking systems in their warehouses since these systems can provide the required flexibility and scalability. Manual systems have been widely studied, but the operating policies may require significant changes for e-commerce settings. First, to maintain consumers' loyalty, it is important to maintain delivery reliability even on the busiest days. When the number of order pickers in an area increases, however, more delays due to interactions may occur. For example, travel speed may need to be lowered when order pickers pass each other in narrow aisles. Second, many products sold through e-commerce are returned by consumers. Before these returned products can be sold again, they must be reintegrated in the stock. This paper presents hybrid genetic algorithms to determine routes for simultaneous pickup of products in response to consumers' orders and delivery of returned products to storage locations. Furthermore, interactions between the order pickers are considered in the routing decisions. The developed algorithms use specific warehouse problem characteristics. We identify the mix of pickups and deliveries to realise the highest savings in practice. It is shown that order-picker interactions can be a significant cause for delay and should be accounted for in the routing.

This paper studies whether time series predictability is consistent with risk-based asset pricing models. Whereas earlier papers – e.g. Kirby (1998), Cecchetti, et al. (2000) and Avramov (2004) – show that returns are too predictable to be explained by rational asset pricing, we find that the predictability typically found in linear forecasting models is not necessarily larger than can be expected from rational asset pricing. More specifically, when preferences are summarized by habit persistence with habit and risk aversion parameters equal to 0.97 and 4.8 (or greater) respectively, a degree of predictability is obtained that is compatible with the predictability found in the recent literature.

The effect of time bucket length on the choice of a lot-splitting approach is studied. Due to the continuing pressure to reduce throughput times and increase efficiency, managers apply various measures, such as lot splitting and cycle time reduction programmes, that change the length of the time bucket in their planning systems. It is shown that the choice for a suitable lot-splitting approach depends on the time bucket length used, so these measures cannot be treated independently as costs may increase rapidly without substantial effect on throughput times. Moreover, the current belief in the lot-splitting literature that the improvements of a variable lot-splitting approach are only marginal compared with an equal sub-batch approach is challenged. Some papers estimate the possible flow time improvement to be less than 5%. It is shown that such statements are not valid as the improvement depends strongly on the type of equal sub-batch strategy applied and the length of the time bucket. Moreover, flow time improvements are accompanied by extra transfer costs, so a cost perspective that includes both effects is more appropriate. The paper shows that equal sub-batching is only effective if information on the time bucket length and on product characteristics is included. At time bucket lengths between one and three days, costs are very sensitive for the type of sub-batching strategy applied. Simulation experiments show that variable sub-batching leads to average cost improvements from 3 to 11%, depending on the time bucket length and the equal sub-batch strategy applied. Lower costs are due to throughput time reductions and transfer cost savings.

This paper discusses the matching conditions resulting from the controlled Lagrangians method and the interconnection and damping assignment passivity based control (IDA-PBC) method. Both methods have been presented recently in the literature as means to stabilize a desired equilibrium point of an Euler-Lagrange, respectively Hamiltonian, system. In the context of mechanical systems with symmetry, the original controlled Lagrangians method is reviewed, and an interpretation of the matching assumptions in terms of the matching of kinetic and potential energy is given. Secondly, both methods are applied to the general class of underactuated mechanical systems and it is shown that the controlled Lagrangians method is contained in the IDA-PBC method. The λ-method as described in recent papers for the controlled Lagrangians method, transforming the matching conditions (a set of non-linear PDEs) into a set of linear PDEs, is discussed. The method is used to transform the matching conditions obtained in the IDA-PBC method into a set of quadratic and linear PDEs. Finally, the extra freedom obtained in the IDA-PBC method (with respect to the controlled Lagrangians method) is used to discuss the integrability of the closed-loop system. Explicit conditions are derived under which the closed-loop Hamiltonian system is integrable, leading to the introduction of gyroscopic terms.

In this paper, we consider a sequence-dependent disassembly line balancing problem (SDDLBP) with multiple objectives that requires the assignment of disassembly tasks to a set of ordered disassembly workstations while satisfying the disassembly precedence constraints and considering sequence-dependent part removal time increments. The four objectives to be achieved are as follows: (1) minimise the number of disassembly workstations, (2) minimise the total idle time by evenly distributing it among workstations, (3) maximise the priority of removing hazardous components as early as possible in the disassembly sequence and (4) maximise the priority of removing high demand components before low demand components. A new approach based on the tabu search (TS) algorithm is proposed to solve the SDDLBP. To the best of our knowledge, this paper investigates the first application of TS algorithm to solve the SDDLBP. Two case scenarios are considered and comparisons with ant colony optimisation and river formation dynamics approaches are provided to demonstrate the effectiveness of the algorithm.

This paper reports a new design of microstrip directional coupler with high directivity. This directional coupler uses corrugated coupled lines and floating conductor in the ground plane of microstrip to enhance coupling. Based on this structure, directional coupler having 4.4% bandwidth has been designed at 4500 MHz with 10 dB coupling and 35 dB directivity. The designed directional coupler has been fabricated and tested for the validity of the design. Measured results are presented in this paper.

Scheduling packaging lines in the process industry is a well known hard problem. The problem becomes even more complicated when each line consists of several machines and an order has to be manufactured on different lines. In this paper we consider the case where a number of orders has to switch from one line to another. This means that an order-run is sometimes manufactured first on the first part of a line and then has to switch to the second part of another packaging line. In this situation the second part of the first line and the first part of the second line cannot be used simultaneously for another run. This situation is studied for the case of the tobacco company Royal Kabat BV. In order to solve the complicated planning problem, the process is partitioned into a Prescheduling Level (PSL) and a Scheduling Level (SL). At the PSL an aggregated plan for a number of successive weeks is made that takes care of the purchasing of packaging materials and the balancing of the capacities. The PSL plan for the current week is the input for the SL at which the actual packaging schedule for that week is made, including the allocation of orders to lines. In this paper we concentrate on the PSL, and our main purpose is to describe the complicated model building process. The model is solved by means of an improvement heuristic on the solution of an LP-relaxation of the model. The computational results show that our partitioning of the problem into a PSL and an SL yields a practically solvable mathematical model; its solutions (i.e. PL plans) are usable for the SL planning and result in practically useful schedules.

Introduction: It is well recognized that a lesion that does not cause a hemodynamically significant stenosis can trigger a sudden cardiac event through plaque rupture. As a diagnostic tool, intravascular imaging was developed to circumvent limitations of coronary angiography; however, none of the intravascular imaging devices are individually able to provide complete assessment of the plaque morphology, geometry, physiology and biology. Therefore, over the past few years an effort was made to develop hybrid intravascular imaging catheters to provide more complete evaluation of coronary plaque pathobiology.Areas covered: This paper aims to give an overview of the recent developments on 1) single-modality intravascular imaging devices; 2) hybrid intravascular imaging devices and 3) the hemodynamic analysis in models reconstructed from the fusion of intravascular imaging and angiographic data.Expert commentary: Within five years, most of the hybrid imaging techniques which are now in pre-clinical phase will be utilized in the clinical arena, as NIRS-IVUS. Software for online blood simulation is likely to be developed that will enable ESS calculation while the patient is in the catheterization laboratory

In this paper, we focussed on Greek employees that are heavily affected by austerity-led organizational changes, and studied whether job crafting (defined as seeking resources, seeking challenges, reducing demands) helps them deal with these changes. In the first, cross-sectional study we examined whether job crafting relates to adaptive performance, and whether individuals’ assessment of changes moderates this relationship. The results showed that the relationship between reducing demands and adaptive performance was positive for those assessing the changes more positively, and negative for those assessing them more negatively. This interaction was replicated in the second, quasi-experimental field study, where we examined the effects of an intervention designed to help employees deal with organizational changes and increase their well-being, adaptive performance and openness to such changes by stimulating job crafting behaviours. Participants received training and worked for 3 weeks on self-set job crafting goals. The intervention was effective in increasing reducing demands, positive affect and openness to change. Moreover, it had a positive effect on openness to change and adaptive performance through positive effect, but a negative effect on adaptive performance through reducing demands. Thus, the intervention facilitated to some extent employee functioning under unfavourable working conditions that result from austerity measures.

WOS: 000465570500006 In this study, (x)%Na2Si3O7/(100 - x)%W glassy structured composites where x = 100, 25 and 60 were prepared for the investigation of their dielectric and gamma-ray shielding properties for the first time. The surface morphology of the samples was imaged by Scanning Electron Microscope. The room temperature complex impedance and dielectric function analysis of the samples revealed that the Na2Si3O7/40%W composite has a promising potential for the decoupling capacitor and electromagnetic shielding applications. From this point of view, the gamma-ray shielding performance of the samples including pure Na2Si3O7 was tested by Ba-133 radioactive point source for transmission of the gamma rays at 81 and 356 keV photon energies. The mass attenuation coefficients (mu/rho) of the composites were measured at these energies by using NaI(Tl) scintillation detector. The experimental half-value layer (HVL), tenth-value layer (TVL) and mean free path (lambda) were also calculated. The theoretical values of the (mu/rho), HVL, TVL and lambda were determined by using Monte Carlo N-Particle simulation code and WinXCom for the comparison. A good agreement between the experimental and theoretical results for the gamma-ray shielding parameters was obtained. While the mass attenuation coefficient increased considerably with an increasing tungsten concentration doping, it decreased with increasing gamma-ray energy. It was observed that the mass attenuation coefficient of Na2Si3O7/40%W composite is higher than that of lead at 81 keV. In addition, HVL, TVL and lambda parameters were found to decrease with increasing W doping. Since there is a good agreement between MNCP results and experimental data, the gamma radiation shielding performance of the samples for some low and high energetic gamma-ray sources such as Am-241, I-131, Cs-137 and Co-60. Ultimately, Na2Si3O7/40%W composite can be suggested as a new alternative non-toxic radiation shielding material for low energetic gamma rays.

WOS: 000458175000001, PubMed: 30264627, Background: Candida sternal wound infections (SWIs) following cardiac surgery are rare but are associated with a high mortality rate. Guidelines on this topic either propose no suggestions for management or offer recommendations based on a small number of reports. Methods: This paper presents a case of a Candida SWI and its successful treatment with debridement using a burr, negative pressure vacuum therapy (NPVT) and dermal grafting. To investigate different methods of treating Candida SWIs following cardiac surgery, a review was completed using the MEDLINE database. Reports without English abstracts and without defined outcomes of therapy for individual patients were excluded. Results: Seventy-seven cases of Candida SWIs following cardiac surgery were identified in 20 articles published since 1999, including our case. Treatment strategies are identified: omentum flap; muscle flap; debridement and secondary wound healing with or without NPVT; debridement and primary closure; incision and drainage; only medical therapy. Patients documented in the articles were classified based on the following outcomes: cured (n = 41 patients [including the present case]), relapse infection (n = 25 patients) and death (n = 11 patients). The various methods used to treat patients were analysed. Conclusions: Delayed closure reoperation with surgical debridement and NPVT have favourable outcomes. In the presence of widespread osteomyelitis, the use of omental flaps is advocated. Treatment with muscle flaps has a high rate of relapse. Debridement and secondary healing or conservative management with antifungals alone can be considered in the treatment of relapsing infection.

0000-0001-5333-5750, WOS: 000477771800005, C120 steel sections are the most widely used post shapes in European guardrail designs. The design length of these posts is determined based on guardrail containment level and engineering judgment. The soil properties where these posts are embedded are usually not considered in design. It is a well-known fact that the crash test performance of soil embedded posts depends mostly on post-soil interaction and post embedment depth (PED). In this study, a series of field impact tests were performed on soil embedded C120 posts to determine optimum PED for three different soil conditions. Seven different PED varied from 650 to 900mm was used for each soil type. Based on these findings a full-scale crash test is performed on a guardrail to verify optimum PED for hard soil conditions. With the use of optimum length guardrail posts considerable amount of installation time, labor and material savings are expected., TUBITAK (Scientific and Technological Research Council of Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [213M516], The work presented in this paper was carried out with funding from TUBITAK (Scientific and Technological Research Council of Turkey), Grant number 213M516.

EgeUn###, In this paper, we study sine-Gordon equation in order to obtain exact solitary wave solutions in the domain of fractional calculus. By using the definition of conformable fractional derivative, we obtain analytical solutions of time, space and time-space fractional sine-Gordon equations. We analyze graphically the effect of fractional order on evolution of the kink and antikink type solitons.

EgeUn###, This paper will investigate wavelet packet transform of acoustic emission (AE) signal processing in order to identify failure mechanisms of unidirectional carbon/epoxy composites. For this purpose, carbon/epoxy composites were tested in tensile test by two different loading conditions. For the first specimen, the load was applied through fiber direction (T0) and for the second specimen, the load was applied perpendicular to the fiber direction (T90), AE signals were collected during experimental test procedure and the signal's waveforms were decomposed into various wavelet levels that each includes details and approximations so-called. Each data is related to a specific frequency range. The results show that type and percentage of failure mechanisms in various loadings are different. In T0, four micro-failure mechanisms of matrix cracking, fiber/matrix debonding, fiber pull-out and fiber breakage were observed and Fiber pull-out was determined as main inter-phase failure mechanism. Debonding were dominant failure micro mechanisms of T90. The results were verified with scanning electron microscopic observations.

[Excerpt] Becoming a teacher entails a complex process which occurs over time in different contexts. Teacher education (TE) plays a central role in it. Although TE has been subject to criticism in regard to its effectiveness in preparing high quality teachers, it does make a difference for quality teachers (Flores 2016). As such, it requires careful programme design, an elaborated view of the intended process of teacher learning, specific pedagogical approaches and an investment in the quality of staff members (Korthagen, Loughran, and Russell 2006). Thus, debates focusing on TE revolve around, amongst other features, its curriculum, its rationale and key components, and its impact on the education and professional learning of preservice teachers (e.g., Darling-Hammond and Lieberman 2012; Livingston and Flores 2017). While teacher education is not to be seen as the panacea to improve education, it certainly does play a role in educating teachers to deal with the increasing complexities of teaching and learning in schools and classrooms in the 21st century. Issues such as motivations for becoming a teacher, the place of reflection in learning to teach, the formation of the professional identity as a teacher, the value of teacher education, the role of teacher educators and the importance of international and comparative perspectives in investigating teacher education are but a few examples of the complex interplay of variables in studying teacher education. The papers included in this issue investigate and discuss these aspects of teacher education.

The Klein-Gordon equation plays an important role in mathematical physics. In this paper, a direct method which is very effective, simple, and convenient, is presented for solving the conformable fractional Klein-Gordon equation. Using this analytic method, the exact solutions of this equation are found in terms of the Jacobi elliptic functions. This method is applied to both time and space fractional equations. Some solutions are also illustrated by the graphics. C1 [Culha, Sevil] Pamukkale Univ, Inst Sci, Denizli, Turkey. [Dascioglu, Aysegul] Pamukkale Univ, Fac Sci & Arts, Dept Math, Denizli, Turkey.

A systematic review was conducted to investigate event-related potentials (ERPs) in response to food and non-food stimuli among individuals with eating and weight disorders. Limiting the search to studies that have analysed ERPs relating to motivated attention and inhibitory control, 19 research papers were extracted from a systematic search in PubMed, Ovid, and Web of Science (2000-2018). An enhanced attentional bias towards food over non-food images (as indexed by P3(00) and LPP amplitudes) was evident for all populations. Individuals with binge eating disorder showed an enhanced attentional response to food cues compared to healthy controls. Inhibitory control-related ERP components (N2(00) and P3a) increased during food-specific no-go trials, but did not differentiate overweight from healthy' weight groups. The N2 amplitude to food pictures were positively correlated with caloric intake and food craving among individuals with obesity and binge eating disorder, respectively, while P3(00) was sensitive to hunger levels among overweight and obese females. The heterogeneity of stimuli/paradigms adopted, component timescales extracted, ERPs analysed, and data presented has challenged this review's ability to produce a robust synthesis of results. Some recommendations for future research are discussed.

In this paper, dynamic elasticity equations for one-dimensional (1D) quasicrystals (QCs) with arbitrary system of anisotropy are considered. Fundamental solutions (FSs) of the phonon-phason displacements, displacement speeds, and stresses arising from pulse point sources are computed. New existence, uniqueness and stability estimate theorems are obtained for dynamic elasticity equations in 1D QCs with the initial conditions (ICs). As a computational example, FS components are computed for orthorhombic and triclinic structures in 1D QCs. C1 [Yaslan, H. Cerdik] Pamukkale Univ, Dept Math, Denizli, Turkey.

0000-0003-1555-6426 WOS: 000482944000001 Accurate prediction of surface subsidence due to the extraction of underground coal seams becomes a significant challenge in engineering. For a projected longwall coal mining operation, conditions of weak cover rock and thick coal seams (6-12 m) in Turgut basin in Yatagan-Turkey are described and discussed based on the field data, using surface deformation prediction system software. This paper aims at predicting the subsidence values only numerically by evaluating the influence of subsidence on irrigation pipeline structure to be built on the ground for the cases with pillars left in the coal seam.

WOS: 000457020400005, This paper investigates the electricity-growth nexus of Gulf Cooperation Council (GCC) member countries from 1980 to 2014. To achieve the goal of this research, both panel cointegration and causality approaches are utilised to examine the long-term and causal relationships between variables. Empirical results confirm the presence of cointegration between variables. Moreover, this study finds that electricity consumption affects the long-term economic growth. Given that GCC member countries are energy-dependent economies, policies that aim to conserve energy consumption may jeopardise economic growth.

ELKOCA, OKTAY/0000-0002-0007-0741 WOS: 000494015900001 This paper presents an experimental study on the mechanical properties of ultra-high-strength steels at elevated temperatures. Tensile tests were carried out at 300-600 degrees C on Docol 1200M and Docol 1400M steel samples. The results indicate that as the temperature increases Young's Modulus, yield strength (YS) and ultimate tensile strength (UTS) display a decrease. YS/UTS ratios at 300 degrees C are lower than those at room temperature, they make peaks at 400 and 500 degrees C for Docol 1400M and Docol 1200M, respectively, and then decrease again beyond those temperatures. While total elongation continuously increases, uniform elongation slightly decreases with increasing temperature. Present carbides in tempered matrix continue to grow and new carbides are observed at the grain boundaries. Considering all roll forming parameters, 300 degrees C seems the most convenient temperature for warm forming. In this sense, the warm roll forming has a potential for forming complex-shaped parts by reconciling strength with formability.

HELHEL, SELCUK/0000-0002-1401-3297 WOS: 000451611800004 Reflection coefficient measurement is one of those fundamental methods for determining the performance of radar absorber materials, and reflections due to these measurements are originated from the discontinuities in the measurement system and they result in error. In this paper, a new technique for the calibration of the scalar reflection coefficient measurements in the frequency range of 3-18 GHz in a portable two-sectioned metallic chamber is being proposed for use in quick laboratory tests with reasonable error (redacted error). Calibration measurements are performed by two calibration standards in frequency domain and transformed to time domain for further calculation. Proposed technique exhibits a good agreement with the theoretical values for especially in compact chambers where plane-wave conditions are not fully satisfied, and it is not in need of any complex time gating process. Furthermore, it does not require considering the phase differences which occurs at the measurement plane, providing a cheap and faster solution, reducing time and complexity in characterization of radar absorber materials. This technique with the mentioned test set-up could supply scalar reflection coefficient measurements with overall 0.55 dB error level and useful for practical applications where high level of accuracy is not required.

This paper challenges the mainstream narrative that links the strength and speed of the world trade collapse in 2008–2009 to the international fragmentation of production, organized in international value chains. The paper points out often overlooked counteracting forces such as non-bank-intermediated credit, trust in long-term commercial affairs and intra-firm relationships. A cross-section of the strength and speed of the import decline in 42 countries shows that both the share of manufacturing trade and an indicator for the vertical specialization in trade are associated with less contraction and slower adjustment. Countries with large shares of manufactures in trade (a proxy for international value chain activity) and/or vertical specialization in trade did not reduce their trade more strongly. The empirical evidence points out that international value chains may very well have had a major dampening effect that reduced the extent to which world trade fell.

In the present paper the authors consider the $\mathcal{P}_{\nu,2}$-transform as a generalization of the Widder potential transform and the Glasser transform. The $\mathcal{P}_{\nu,2}$-transform is obtained as an iteration of the the $\mathcal{L}_{2}$-transform with itself. Many identities involving these transforms are given. By making use of these identities, a number of new Parseval-Goldstein type identities are obtained for these and many other well-known integral transforms. The identities proven in this paper are shown to give rise to useful corollaries for evaluating infinite integrals of special functions. Some examples are also given as illustration of the results presented here., Comment: 13 pages

In this paper, we investigate the use of a continuous algorithm for the no-idle permutation flowshop scheduling (NIPFS) problem with tardiness criterion. For this purpose, a differential evolution algorithm with variable parameter search (vpsDE) is developed to be compared to a well-known random key genetic algorithm (RKGA) from the literature. The motivation is due to the fact that a continuous DE can be very competitive for the problems where RKGAs are well suited. As an application area, we choose the NIPFS problem with the total tardiness criterion in which there is no literature on it to the best of our knowledge. The NIPFS problem is a variant of the well-known permutation flowshop (PFSP) scheduling problem where idle time is not allowed on machines. In other words, the start time of processing the first job on a given machine must be delayed in order to satisfy the no-idle constraint. The paper presents the following contributions. First of all, a continuous optimisation algorithm is used to solve ...
