In this paper, the single center vortex method (SCVM) is extended to find some vortex solutions of finite core size for dissipative 2D Boussinesq equations. Solutions are expanded in to series of Hermite eigenfunctions. After confirmation the convergence of series of the solution, we show that, by considering the effect of temperature on the evolution of the vortex for the same initial condition as in [19] the symmetry of the vortex destroyed rapidly.
Phytochemical and Bioactive Properties of Phelypaea Tournefortii – Effect of Parasitic Lifestyle and Environmental Factors
Authors: Piwowarczyk Renata , Ochmian Ireneusz , Lachowicz Sabina , Kapusta Ireneusz , Sotek Zofia
Published: July 2020

Some holoparasitic species can become cultivated plants due to their unique chemical composition. A lot of bioactive contents are characteristic for them. Holoparasites of the family Orobanchaceae are known to be an important and rich source of polyphenols, especially metabolites of the phenylethanoid glycosides (PhGs) group. However, only a minority of the species in this family have been phytochemically tested. They are reported to have multiple biological and therapeutic effects and have been used for centuries in traditional Chinese medicine. This is the first study to present phytochemical profiling for a representative of genus Phelypaea. The chemical composition and biological activity in particular organs of the parasite, P. tournefortii, were determined. The interaction with its host, Tanacetum polycephalum (Asteraceae), from different places and altitudes was also studied. We presented the determination of polyphenolic compounds with the UPLC-PDA-MS/MS method, antioxidative effects and inhibitory activities, polyphenols, and nitrates content, ABTS•+, DPPH, FRAP, as well as colour parameters. The polyphenols profile of the parasite and host were different in quality and quantity. Identification of polyphenolic compounds revealed 41 compounds, 15 in the parasite (12 phenylethanoids and 3 anthocyanins), and 26 in the host (mainly flavonoids and phenolic acids). The amount and biological activity of polyphenolic compounds present in Phelypaea was very diverse and depended on the host plant and the parasite’s organs, as well as on population altitude. The results show that P. tournefortii is a potential source of functional and pro-health components. They also direct researchers’ attention to the parasite’s organs, host, and environmental influence.

Authors: Farooq Assad , Irshad Farida , Azeemi Rizwan , Iqbal Nadeem
Published: July 2020

Softener application on fabric surface facilitates the process and wear abilities of the fabric. However, the application of softeners and other functional finishes influence the color of dyed fabrics, which results in shade change in the final finished fabrics. This article presents the method of intelligent prediction of the shade change of dyed knitted fabrics after finishing application by using artificial neural networks (ANNs). Individual neural networks are trained for the prediction of delta values (ΔL, Δa, Δb, Δc, and Δh) of finished samples with the help of reflectance values of the knitted dyed samples along with color, shade percentage, and finishing concentrations, which were selected as input parameters. The trained ANNs were validated through “holdout” and “cross-validation” techniques. The trained ANNs were combined to develop the model for shade prediction. The developed system can predict the shade change with >90% accuracy and help to decrease the rework and reprocessing in the wet processing industries.

Model-driven decision support to facilitate efficient fresh food deliveries
Authors: Fikar Christian
Published: July 2020

The delivery of fresh food is challenged by various uncertainties present in daily logistics operations. To facilitate successful operations, this work reviews the recent work on model-driven decision support systems to identify research gaps and derive implications. Introduced systems in literature mainly employ simulation or optimization methods and focus on the consideration of industry specifics such as short shelf lives and the importance of efficient temperature control. Therefore, food quality models are often integrated to enable one to monitor quality throughout supply chain operations and adjust planning procedure respectively. To strengthen research, future work focusing on a stronger consideration of customer-related factors and holistic approaches considering various interdependencies present in fresh food logistics operations are required.
Emotional Valence Coded in the Phonemic Content – Statistical Evidence Based on Corpus Analysis
Authors: Slavova Velina
Published: July 2020

This study investigates the relationship between the phonemic content of texts in English and the emotional valence they inspire. The sublexical content is presented in terms of biphones composed by one vowel and one consonant. The statistical analysis of a vast corpus of emotionally evaluated sentences reveals a strong correlation between this sublexical presentation and the evaluations of valence provided by the readers. An initial test performed with other valence-rated prose texts makes believing that the feature observed within the corpus can be useful for the emotion classification of texts.
The benefits of the Velvet Revolution in Armenia: Estimation of the short-term economic gains using deep neural networks
Authors: Nahapetyan Yervand
Published: July 2020

This article primarily aims to estimate the impact of the Armenian revolution and test the hypothesis, that is, the benefits of revolution and establishment of democracy can be seen even in the first year after the political change. To calculate the short-term net surplus of the revolution, we estimated the difference between the projection of Armenian economic activity for the four quarters after the revolution, using only pre-revolutionary (assuming there was no revolution) and real data for the same period after the revolution. Using deep neural network models, such as recurrent neural networks and convolutional neural networks (CNN), we compared prediction accuracy with structural econometrics, such as autoregressive integrated moving average and error correction model, using pre-revolutionary data (2000Q1–2018Q1) for Armenia and combinations of models using an ensembling mechanism. As a result, CNN overperformed the rest of the models. The CNN simulation on post-revolutionary data indicates that during the period 2018-Q2–2019-Q1, Armenia gained approximately 850 million EUR in terms of GDP, thanks to the revolution and the new government. Moreover, out of seven models, the five best models in terms of accuracy indicated that the revolution had no negative impact on the Armenian economy, as the actual values were within or above the 95% confidence interval of the prediction.
The Use of Bark in Biomonitoring Heavy Metal Pollution of Forest Areas on the Example of Selected Areas in Poland
Authors: Świsłowski Paweł , Kříž Jan , Rajfur Małgorzata
Published: July 2020

In the year 2016, passive biomonitoring studies were conducted in the forest areas of southern and north-eastern Poland: the Karkonosze Mountains (Kark), the Beskidy Mountains (Beskid), Borecka Forest (P. Bor), Knyszynska Forest (P. Kny), and Białowieza Forest (P. Bia). This study used bark from the tree, Betula pendula Roth. Samples were collected in spring (Sp), summer (Su), and autumn (Au). Concentrations of Mn, Fe, Ni, Cu, Zn, Cd, and Pb were determined for the samples using the atomic absorption spectrometry method with flame excitation (F-AAS). Based on the obtained results, the studied areas were ranked according to level of heavy-metal deposition: forests of southern Poland > forests of north-eastern Poland. Some seasonal changes in the concentrations of metals accumulated in bark were also indicated, which is directly related to their changing concentrations in the air during the calendar year, for instance, the winter heating season produces higher concentrations of heavy metals in the bark samples taken in spring. When deciding to do biomonitoring studies using bark, but also other biological materials, it is necessary to take into account the period in which the conducted research is done and the time when the samples are taken for analysis, because this will have a significant impact on the obtained results.

Published: July 2020

As a result of studying the vegetation cover of artificial (possibly spontaneous) tree plantations on the hills of the right bank of the River Dnieper in the Forest-Steppe of Ukraine we discovered the formation of natural populations of Cephalanthera damasonium (Mill.) Druce. Information on the growth of this species was previously presented (more than 80 years ago) by F. Gryn (samples of which are in The National Herbarium of Ukraine, Kiev), who noted its distribution in these locations. The ecological and coenotic features of the distribution of this species as a part of available populations in the communities of classes Carpino-Fagetea sylvaticae, Quercetea pubescentis, Crataego-Prunetea, Alno glutinosae-Populetea albae have been studied. The largest eight new populations of C. damasonium have been identified on the eastern border of Ukraine. Habitat conditions, number and structure of all new populations were determined. Micropopulations of the species occupy an area from several to 750 m2 with a total population of more than 1,200 specimens. The ontogenetic spectrum is right-sided, with a dominance of generative individuals, and their share is 4/5 of the total number of individuals. The peculiarity of this locality is the high number of individuals in most of these populations, which may be due to favourable ecological-coenotic conditions and the absence of intensive anthropogenic influences. The identified habitats of the study species need protection.
Outline of the development of research on the impact of Neolithic settlements on the transformation on loess landscapes in southern Poland
Authors: Ryzner Kamila , Owczarek Piotr
Published: July 2020

During the last few decades, many case studies have focused on landscape transformations in response to water erosion, human impact, and climate changes. This article presents a review and comparison of the current state of knowledge on conducted research on the impact of the activities of early humans on the relief and forms of loess areas in Poland based on the results of a variety of dating methods (OSL, TL, C14, 137Cs, palynology, dendrochronology etc.). The influence of land-use activity since the first permanent settlements (8,000–5,200 BP) played a major role in the development of certain sand sediment terrain forms: gullies, river terraces, the filling of isolated depressions and alluvial fans in the loess areas. As a result, a simplified scheme of landscape evolution was created along with a map of the most investigated areas by authors. The main problem was to differentiate the influence of anthropogenic factors from natural ones occurring either simultaneously or alternatively. The developed deposits form a geo-archive which has recorded the history of environmental changes. A detailed analysis of the sedimentary structures provides the possibility to reconstruct and understand past functional responses in natural systems. It is important to consider the impact of climate change and human influence over the course of history on a specific geomorphological system. This can help to predict future land changes and likely hazards.
The Dynamic Linkage between Money Market, Capital Market and Economic Growth in Ghana: New Lessons Relearned
Authors: Ogbuji Isaac A. , Mesagan Ekundayo P. , Alimi Yasiru O.
Published: July 2020

This study is a comparative analysis of the effects of money and capital markets on the Ghanaian economy covering the period from 1991 to 2017 using the dynamic Auto Regressive Distributed Lag (ARDL) framework. Empirical results confirmed the existence of a unique and stable long-run relationship between the money market, capital market and economic growth. In respect of money market indicators, findings confirmed that monetary policy and treasury bills rate have had negative but significant impact on growth in the short- and long-run respectively. More so, total liquidity negatively and significantly influenced the Ghana-ian economy both in the short- and in the long run. Both market capitalisation and total value of stock traded, as proxies of capital market, had positive and significant effects on short-run growth, while both indicators as well as stock market turnover negatively and insignificantly affected long-run growth. This means that capital market exerts a short-run impact on the country’s economy, while money market exerts both short- and long-run impacts. The lesson relearned is that the money market propels the Ghanaian economy better than the capital market.
Syntheticising Scandinavia: The Introduction of Synthetic Pesticides to Scandinavian Gardens, 1945-1952
Authors: Nielsen May-Brith Ohman
Published: July 2020

This study examines the introduction of prescriptive pesticide technologies into Scandinavian family gardens. It analyses pesticide propaganda and plant protection experts’ advice and instructions on the use of pesticides directed at amateur, home gardeners in Norway, Sweden and Denmark in the years between 1945 and 1952, the period when the new generation of synthetic pesticides was introduced in Scandinavia, and eagerly advocated by the leading experts of plant protection science. The sources investigated are gardening magazines and their special issues on garden instruction and the use of chemicals through the seasons, edited, published and distributed to a wide readership by national gardening associations. The study shows how the gardening associations in Scandinavia and their popular gardening magazines were major pushers of extensive pesticide spraying practices, with supporting epistemic logic, onto the numerous family gardeners of Scandinavia. Through these gardening associations both the state plant protection authorities and their scientific expertise and also the pesticide companies reached wide groups of citizens, across diverse professions, occupations and ways of life. This served to normalise the use of powerful poisons in small gardens and small-scale food production.
Radiation Disinfestation of Honeybee Combs Infested with Greater Wax Moth Eggs
Authors: Mansour Mohammed
Published: July 2020

The sensitivity of different developmental stages of greater wax moth (Galleria mellonella L.) eggs to gamma irradiation was examined. Eggs, 25 to 144 h-old, were exposed at 48 h intervals to gamma radiation dosages (50 to 400 Gy), and the effects on egg hatch, pupation and adult emergence were investigated. The developmental rate of irradiated-egg larvae and pupae to adult stage was also studied. Results showed that the irradiation sensitivity of G. mellonella eggs decreased with increased age of the eggs when irradiated. In 25–48 h-old eggs, 50 Gy dose significantly reduced egg hatch and at 200 Gy dose no egg hatch was observed. Eggs 73–96 h-old were slightly more tolerant to irradiation treatment; hatching completely ceased at 250 Gy dose. Sensitivity to gamma irradiation reached its lowest level however when 121–144 h-old eggs (few h. before egg hatch) were irradiated. 350 Gy dose reduced egg hatch to about 3%, and at 400 Gy no egg hatch was noted. Survival to the adult stage was also negatively affected. At the most radio-tolerant stage (121–144 h-old), 100 Gy dose significantly reduced larval survival to the adult stage and 300 Gy completely prevented it. The development rate of larvae and pupae resulting from irradiated eggs was also negatively affected.
Evidence-based Nomenclature and Taxonomy of Research Impact Indicators
Authors: Arsalan Mudassar , Mubin Omar , Al Mahmud Abdullah
Published: July 2020

Purpose

This study aims to classify research impact indicators based on their characteristics and scope. A concept of evidence-based nomenclature of research impact (RI) indicator has been introduced for generalization and transformation of scope.

Design/methodology/approch

Literature was collected related to the research impact assessment. It was categorized in conceptual and applied case studies. One hundred and nineteen indicators were selected to prepare classification and nomenclature. The nomenclature was developed based on the principle—“every indicator is a contextual-function to explain the impact”. Every indicator was disintegrated into three parts, i.e. Function, Domain, and Target Areas.

Findings

The main functions of research impact indicators express improvement (63%), recognition (23%), and creation/development (14%). The focus of research impact indicators in literature is more towards the academic domain (59%) whereas the environment/sustainability domain is least considered (4%). As a result, research impact related to the research aspects is felt the most (29%). Other target areas include system and services, methods and procedures, networking, planning, policy development, economic aspects and commercialisation, etc.

Research limitations

This research applied to 119 research impact indicators. However, the inclusion of additional indicators may change the result.

Practical implications

The plausible effect of nomenclature is a better organization of indicators with appropriate tags of functions, domains, and target areas. This approach also provides a framework of indicator generalization and transformation. Therefore, similar indicators can be applied in other fields and target areas with modifications.

Originality/value

The development of nomenclature for research impact indicators is a novel approach in scientometrics. It is developed on the same line as presented in other scientific disciplines, where fundamental objects need to classify on common standards such as biology and chemistry.

Combined analysis of onco-epidemiological studies of the relationship between lung cancer and indoor radon exposure
Authors: Yarmoshenko Ilia V. , Malinovsky Georgy P.
Published: July 2020

Objectives: Recent results of epidemiological and medical statistics studies of lung cancer and indoor radon in different regions of the world make a relevant new combined analysis of residential exposure health effects. In particular, new data were obtained by means of a meta-analysis of case-control studies as well as taking into account a confounding effect of human papillomavirus infection in studies of geographically aggregated data.

Materials and methods: Two sources of epidemiological data are considered: (1) studies of ecological design and (2) case-control studies. Ecological studies included the analysis performed for the USA counties and Russian oblasts with adjusting for the main confounders. Data on the case-control studies were gained from the meta-analysis of 31 individual studies with a weighting of obtained odds ratios according to the quality of radon exposure reconstruction and size of the reference group. Estimations of lung cancer excess relative risk (ERR) associated with indoor radon exposure are combined.

Results: Two types of epidemiological study design provided generally consistent EER estimations. The combined value of ERR due to radon exposure is 0.14 (90% CI: 0.10–0.18) per 100 Bq/m3.

Conclusion: Available geographically aggregated data in regions of Russia and the United States and the meta-analysis of case-control studies conducted in a large number of countries confirm the association of lung cancer with indoor radon exposure.
Low cost blood vein detection system based on near-infrared LEDs and image-processing techniques
Authors: Alwazzan Mohammed J.
Published: July 2020

Drawing blood and injecting drugs are common medical procedures, for which accurate identification of veins is needed to avoid causing unnecessary pain. In this paper, we propose a low-cost system for the detection of veins. The system emits near-infrared radiation from four light-emitting diodes (LEDs), with a charge-coupled device (CCD) camera located in the middle of the LEDs. The camera captures an image of the palm of the hand. A series of digital image-processing techniques, ranging from image enhancement and increased contrast to isolation using a threshold limit based on statistical properties, are applied to effectively isolate the veins from the rest of the image.
Process of Incorporation and Morphological Transformations of Rural Settlement Patterns in the Context of Urban Development. The Case Study of Łódź
Authors: Figlus Tomasz
Published: July 2020

The subject of the research covers the problem of morphological changes in former villages incorporated into the city on the example of Łódź. The first objective of the article is to analyse the urban development of the city, taking into account the territorial changes and incorporation of villages. The second objective includes the analysis of morphological changes in former villages that have taken place after their incorporation into the city since the mid-twentieth century. The study required analysis of source materials in the form of preserved historical maps and today's plans, legal acts, planning documents and chosen statistical data. The analysis of changes in the spatial structure of villages incorporated into the city was possible mainly thanks to the retrogressive, as well as progressive method. The article also uses the method of morphological analysis of the city plan based on the Conzenian tradition of urban morphology. The study applies the typology of rural settlement patterns, taking into account the issue of morphological changes and relics of morphological features from the period before the incorporation into the city. It is characteristic that the transformation process of rural settlement patterns took place in different ways and with various intensity depending mostly on the scale of urbanisation processes. It was possible to distinguish the orthomorphic transformations, where all spatial modifications were mainly additions and did not destroy the morphogenetic core, so the former layouts have been preserved almost completely, semi-metamorphic transformations, where spatial reorganisation was considerable, but not total, and clear relics of the historical rural settlement pattern have been saved, and metamorphic transformations, in which almost all elements of the former morphological structure have been completely erased and the former layouts have been totally changed.

Published: July 2020

Lithium additions to Al offer the promise of substantially reducing the weight of alloys, since each 1 wt. % Li added to Al reduces density by 3 % and increases elastic modulus. In the present work, the effect of 1.46 wt. % Li addition to AlSi7Mg (containing 7.05 wt. % Si and 0.35 wt. % Mg) was studied. The alloy showed reduced density and higher hardness after natural ageing. Experimental work showed that micro-structural and mechanical properties changed with Li addition. It was observed that 0.80 wt. % Li addition resulted in formation of new phase AlLiSi which has a great effect to increase hardness of AlSi7Mg. According to Scanning Electron Microscope (SEM) and X-ray diffraction analysis it was confirmed that the addition of Li causes formation of different phases which are: α-Al, β-Si and AlLiSi.

European Regional Airport: Factors Influencing Efficency
Authors: Nõmmik Allan , Antov Dago
Published: July 2020

During the recent decade a lot of research has been focused on identification of the importance of regional airport for the local economy and the measuring and predicting of the airport’s efficiency. With regard to individual airport planning it turns out that airports are not free in the optimization of infrastructure due the need to comply international aviation standards and recommended practices, one the one hand, and the tendency of air transportation system development including aircraft design and airlines’ fleet development, on the other. Furthermore, it is also important to take into account the specificity of each particular airport, including the traffic variability resulting from seasonality, with the airport’s mission geared to it. We found, tha t one of the reasons for the relatively low efficiency of regional airports, given the general trend in the growth in the number of seats for narrow-body aircraft. Likewise, it has been found, that the seasonality of air traffic at regional airports is comparatively high. In addition, this paper spotlights the ways the theoretical model of returns to scale affects the efficiency of the apron of the regional airport and briefly discusses the different interpretations of the definition of regional airport.

The issue of active protests against the injustice of the law aimed at bringing about a change in that conduct is of great relevance for members of the world society. There is no escape from admitting the fact that even the most perfect political system may and will from time to time produce unjust laws. What is as yet unclear is the principles of justification in favour of a civil disobedient who commits an open breach of that laws. The present article defines the features that make an act of civil disobedience something more than a simple breach of a law. The purpose of this article is to justify civil disobedience as a unique political category, which makes social choice and legal change possible.
ADVANCING STUDENT MOTIVATION AND COURSE INTEREST THROUGH A UTILITY VALUE INTERVENTION IN AN ENGINEERING DESIGN CONTEXT
Authors: Turoski Staci A. , Schell William J.
Published: July 2020

Understanding and improving student motivation is critical for educators because motivation is essential for academic success.  Student motivation is multifaceted and complex with interest as one of many factors related to motivation and motived behavior. Student interest in course material can be supported by helping them understand the value and relevance of the material to their life.  Within an expectancy-value framework, one aspect for understanding students perceived task value is to assess their perception of the utility value, or their view of the usefulness, of the task to their present or future goals.  One way to encourage value is to have students write about the relevance of the course material to their life through structed utility value interventions.  This study will compare the performance, interest, and motivation between students who participated in structured utility value interventions and those in a control group who did not during a third year multidisciplinary engineering design course.  Initial indications are that students’ interest and motivation increase when given the utility value intervention.

Published: July 2020

Equine gammaherpesvirus 2 (EHV-2) has been linked to keratitis and keratoconjunctivitis but has also been isolated in horses showing no signs of disease. The aim of the current study was to assess the importance of EHV-2 infection in the aetiopathogenesis of ocular disease, where the applied treatment failed. Seventy-eight horses with nonhealing ocular disease were examined at the Equine Clinic of the University of Veterinary Medicine and Pharmaceutical Sciences, Brno, Czech Republic, between the years 2009 and 2016. In total, 96 conjunctival swabs were taken and, starting from 2014, peripheral blood leukocytes (PBLs) were also examined in 42 patients. Positive EHV-2 results were detected in 53 ocular swab samples (54.64%) and in 22 PBL samples (51.16%). The horses were divided into three groups according to age, up to 3 years, from 3 to 15 years and older than 15 years. Depending on the clinical presentation, horses were also divided into nonulcerative or ulcerative keratitis, keratouveitis, keratoconjunctivitis, and corneal degeneration groups. The group of young horses had a significantly higher ocular swab positivity compared to the middle group (P= 0.01). Increased bilateral ocular occurrence with decreasing age was observed, although it was not significant (P= 0.04). Significant correlation was confirmed between PBL samples and ocular swabs (P= 0.01). This correlation was even higher in cases of bilateral infection. No significant differences were detected when comparing the groups according to the clinical presentation. This study describes the prevalence of EHV-2 in different age group horses with non-healing keratopathies.

Published: July 2020

The Lithuanian Žemaitukai horse breed is one of the oldest in Europe. Currently, there is a lack of information about the effect of endurance competition on blood indices and acid–base balance in the Žemaitukai horses. The aim of this study was to evaluate the effect of endurance exercise on the acid–base balance and electrolyte indicators of the Žemaitukai horses in an official endurance competition. In total, 48 horses of the Žemaitukai breed competed in endurance competitions over the same distance (60 km). Samples were taken before and immediately after the exercise. The following indicators were analysed: the hydrogen potential (pH), partial carbon dioxide pressure (pCO2), partial oxygen pressure (pO2), base excess in blood (BE), base excess in the extracellular fluid [BE (ecf)], cHCO3(bicarbonate), cSO2(oxygen saturation), tCO2(blood total carbon dioxide), haematocrit (HCT), haemoglobin concentration (cHgb), sodium (Na), potassium (K), calcium (Ca), chlorides (Cl), and lactate (Lac). Increase in pH showed adaptation of the horse metabolism to exercise. Blood changes were caused by the development of dehydration and metabolic alkalosis. According to Lac results, all horses were fit and tolerated well physical activity. The exercise did not significantly affect the demand for minerals. Based on the results obtained, it can be stated that horses of the Žemaitukai breed are suitable for endurance competing.

Non-uniform corrosion of steel rebar and its influence on reinforced concrete elements` reliability

Published: July 2020

Remarkable place of reinforced concrete structures in construction field has been noted in wide number of recent researches. Subsequently, their degradation due to aggressive environment has become the topical problem nowadays. Therefore, the formulation of reliable technique for corroded element strength decrement is of great importance, and could be achieved only with the use of complex experimental and theoretical analysis. In this article an attempt is made to propose the mathematical approach to corrosive process modelling, taking into consideration the specifics of its development. According to thorough literature review on existing studies, main specifics of the process were indicated for further suppositions and assumptions formulation. Accordingly, the complex theoretical investigation with corresponding mathematical computations was conducted and results of analytical modelling were discussed. As the initial data for analytical modelling results of previously conducted experiments were used. Analysis of the obtained results shows rather high correspondence with the real conditions of structural element exploitation, taking into consideration material anisotropy and complexity of the corroded zone spread along the rebar cross-section. Proposed methodology for limit force decrease evaluation in general demonstrates reliable results and could be used for further evaluation of corrosion impacts on reinforced concrete elements bearing capacity.
Development of a test method to investigate mode II fracture and dissection of arteries
Authors: FitzGibbon Brian , McGarry Patrick
Published: July 2020

The current study presents the development and implementation of a bespoke experimental technique to generate and characterise mode II crack initiation and propagation in arterial tissue. The current study begins with a demonstration that lap-shear testing of arterial tissue results in mixed mode fracture, rather than mode II. We perform a detailed computational design of a bespoke experimental method (which we refer to as a shear fracture ring test (SFRT)) to robustly and repeatably generate mode II crack initiation and propagation in arteries. This method is based on generating a localised region of high shear adjacent to a cylindrical loading bar. Placement of a radial notch in this region of high shear stress is predicted to result in a kinking of the crack during a mode II initiation and propagation of the crack over a long distance in the circumferential (c)-direction along the circumferential-axial (c-a) plane. Fabrication and experimental implementation of the SFRT on excised ovine aorta specimens confirms that the bespoke test method results in pure mode II initiation and propagation. We demonstrate that the mode II fracture strength along the c-a plane is eight times higher than the corresponding mode I strength determined from a standard peel test. We also calibrate the mode II fracture energy based on our measurement of crack propagation rates. The mechanisms of fracture uncovered in the current study, along with our quantification of mode II fracture properties have significant implications for current understanding of the biomechanical conditions underlying aortic dissection.
Local use-dependent activity triggers mind wandering: resource depletion or executive dysfunction?

Published: July 2020

Mind wandering (MW) is a highly prevalent phenomenon despite its negative consequences on behaviour. Current views about its origin share the idea that MW occurs due to changes in the executive functions system. Here, we argue that not all instances of MW are necessarily related to changes in that system. Combining results from MW and sleep research, we propose that MW could also be related to the depletion of resources in primary task-related networks. To test this hypothesis, participants performed four sessions of the texture discrimination task (TDT) on a day. The TDT is a perceptual learning task in which performance is negatively related to the local build-up of sleep pressure. During the TDT, MW was recorded in both a subjective (i.e., with thought probes) and an objective (i.e., phasic pupillary response) manner. Results showed that accuracy on the TDT was mirrored in the objective measure of MW. For the subjective measure, the pattern was similar to that of task performance but could not be interpreted as reliable. These results demonstrate that not all MW is necessarily related to changes in the executive system and support the hypothesis that MW could be related to the depletion of local, task-related resources.
Soft Skills as Employability Skills: Fundamental Requirement for Entry-level Jobs
Authors: Subedi Netra Bahadur
Published: July 2020

In spite of the fact that the term ‘soft skills’ is new in our context, it has a wide range of implications and effects. Soft skills are intangible, nontechnical, personality-specific skills that determine one’s strengths as a leader, facilitator, mediator, and negotiator. Soft skills are contrasted to hard skills in a sense that hard skills are limited to specific area. It is to be noted that in the course of seeking an employment in the market, individual’s soft skills are as important as hard skills. It is found that person’s hard skills lead an individual to the entrance of job market, soft skills guarantee the job opportunity and further career growth. It is urgent that we have to instill our graduates with remarkable amount of soft skills for quick employment. It is always advisable that the companies select human resources with the best non-technical skills that are likely to be available in the labour market. It is further important to foster and develop the employees. Thus, these inter-sectional skills are really important for the promotion and enhancement of the organization. Owing to the same fact, this paper argues how soft skills as employability are fundamental requirement for entry-level Jobs.

Design of low profile sample stage
Authors: Cooper Simon
Published: July 2020

The Italian Neutron Experimental Station, or INES for short, instrument beamline at the ISIS Neutron and Muon Spallation Source recently underwent an upgrade to its sample positioning area to improve the sample handling capability and capacity of the instrument. INES is a powder diffractometer instrument devoted to materials characterization and cultural heritage studies. Due to the types of samples received for cultural heritage studies the instrument scientists wanted to maximize the height of samples that could be scanned with the instrument. This paper covers the in-house design and delivery of a new, two axis, linear positioning stage for INES that due to the addition of a new linear height stage, needed to be as low profile as possible to give the instrument scientists the sample capacity they required.
