The World of Iberian Ham and its Tourist Potential in the Sierra De Huelva (Andalusia, Spain)
Authors: Pizarro-Gómez Antonio , Šadeikaitė Giedrė , García-Delgado F. Javier 
Published: October 2020

Abstract
In the context of agricultural post-productivity, rural spaces acquire new functions or reinforce the existing ones. Thus, the production of quality food, as a part of agroindustry, and tourism appear as common activities in rural development strategies. Special attention is drawn to gastronomic tourism and the creation of routes as a creative expression of the integration and structuring of the territories. The Iberian ham is a unique product, known worldwide, produced exclusively in the SW quadrant of the Iberian Peninsula. It is linked to a unique agro-system of the anthropised Mediterranean forest, also known as dehesa4
, and comparably limited Iberian pig livestock, which has given rise to traditional culture and industry constituted in Local Productive System in many municipalities, supported by Protected Designation of Origin. The central objective of the research is to analyse existing tourist attraction related to the Iberian ham, its potential and the routes and products that have arisen around it. Having placed the territorial recognition as the starting point, the analysis of the resources and locations of the activities related to the Iberian ham was carried out based on scientific literature and the use of different databases. Secondly, the analysis of the potential tourism activities in the Sierra de Huelva region was implemented based on primary sources, namely surveys and interviews with intervening actors. The following results are obtained: a) the tourist potential of the Iberian pig world; b) complementarity with other tourist activities; c) difficulties in structuring existing attractions; d) multiplication of disconnected and sometimes coincident tourism initiatives; e) scarce participation of private actors in the initiatives launched.

Published: October 2020

Abstract
Ensuring aircraft are technically safe to operate is the realm of airworthiness, literally worthy of being in the air. This is achieved not only with technological tools and techniques, or with just personnel and manpower, it is guided and supervised by managers and leaders. As such, the objective of this paper is to understand the role leadership plays in maintaining aviation safety and aircraft airworthiness. To this end, a case study of the Hawker Sidley Nimrod XV230 accident that occurred on September 2, 2006 near Kandahar in Afghanistan, was utilized. The study concluded that leadership is a key aspect, specifically finding that leaders are responsible for articulating the organizations vision, strategic objective setting, and monitoring the achievement of those objectives. It was concluded that operational airworthiness is directly dependent on the leadership ability to provide direction, workplace culture, continued learning, and establish risk management systems for safe and airworthy operations.
Mining Cardinality Restrictions in OWL
Authors: Potoniec Jedrzej 
Published: October 2020

Abstract
We present an approach to mine cardinality restriction axioms from an existing knowledge graph, in order to extend an ontology describing the graph. We compare frequency estimation with kernel density estimation as approaches to obtain the cardinalities in restrictions. We also propose numerous strategies for filtering obtained axioms in order to make them more available for the ontology engineer. We report the results of experimental evaluation on DBpedia 2016-10 and show that using kernel density estimation to compute the cardinalities in cardinality restrictions yields more robust results that using frequency estimation. We also show that while filtering is of limited usability for minimum cardinality restrictions, it is much more important for maximum cardinality restrictions. The presented findings can be used to extend existing ontology engineering tools in order to support ontology construction and enable more efficient creation of knowledge-intensive artificial intelligence systems.
Bacterial wetwood of silver birch (Betula pendula roth): symptomology, etiology and pathogenesis
Authors: Goychuk Anatoliy F. , Drozda Valentin F. , Shvets Marina V. , Kulbanska Ivanna 
Published: October 2020

Abstract
The article is focused on microbiological and silvicultural properties of bacterial wetwood of silver birch (Betula pendula), also known as European white birch. During the active phase of the disease, bacterial wetwood (i.e. bacterial dropsy, vascular parenchymatous bacteriosis or flux slime) is characterised by crust and periderm bloating, necrotic wet stains and abundance of exudate. The disease is more likely to occur in older (r = 0.56, p < 0.01) and less-dense (r = −0.29, p < 0.01) stands.
The statistical model showed that the chance of bacterial wetwood increases with birch age by 0.36% per year. The stands with birch proportion of over 70% demonstrated 15.3% lower infection rate compared to the stands with lower birch presence. The stands with lower stocking demonstrated a higher proportion of infected tree distribution by 7.5% compared to the stands with higher birch representation. The most vulnerable were larger, older B. pendula trees with longitudinally fissured bark that grow on poorer soils and experience frequent water stress.
Birch associations with Pteridium aquilinum and Vaccinium myrtillus were more susceptible to infection (31.6% and 44.3%, respectively), whereas associations with Brachypodium sylvaticum, Sphagnum palustre and Calluna vulgaris were at lower risk. Strong ecological and trophic association of bacterial wetwood was present between silver birch and Tremex spp., particularly Tremex fuscicornis. Mycobiota was represented by Rhizopus microsporus, Mucor mucedo, Penicillium aurantiogriseum, Penicillium purpurogenum and Acremonium strictum.

Enterobacter, Xanthomonas, Pantoea and Bacillus spp. associated with bacterial wetwood of silver birch were isolated. Enterobacter nimipressuralis was found to be the primary causative agent through means of artificial infection, while other bacteria were found to be either weak pathogens or concomitant. E. nimipressuralis formed the largest number of colony-forming units (CFU) for bark and cambium (164 and 127 CFU, respectively) and was also found in a small amount as a vital obligate in the automicrobiota in healthy birch trees.

Abstract
Cornelian cherry fruits are quite rich in bioactive compounds. Natural colour, rich flavonoids and anthocyanins and high antioxidant activity have made the fruits a natural drug. In the present study, antioxidant activity, total flavonoids and total phenolics of naturally growing 18 cornelian cherry genotypes with different phenotypic characteristics were determined. Size and shape parameters of the genotypes were also determined with the image-processing method; sphericity, elongation and shape index were calculated and shapes of two-dimensional fruit images were compared with elliptic Fourier analysis. Antioxidant activity, total flavonoid contents and total phenolic amounts of the genotypes were varied between 55.062 and 152.420 mmol TE · kg−1, 286.40 and 2,882.80 mg QE · kg−1, and 2,644.80 and 12,959.00 mg GAE · kg−1, respectively. Multivariate variance analysis conducted based on physical characteristics revealed that six genotypes were different from the others. Shape analysis with Elliptic Fourier method revealed that the majority of present cornelian cherry genotypes had an oval appearance and a small portion of them had a drop-like appearance. According to discriminant analysis and Hotelling's pair-wise comparison tests, there were five different shape groups for present genotypes. A single genotype was placed into one of these groups, thus it was determined that this genotype was totally different in shape from the others.

Tetanus in Animals — Summary of Knowledge
Authors: Malinovská Z. , Čonková E. , Váczi P. 
Published: October 2020

AbstractTetanus is a neurologic non-transmissible disease (often fatal) of humans and other animals with a worldwide occurrence.Clostridium tetaniis the spore producing bacillus which causes the bacterial disease. In deep penetrating wounds the spores germinate and produce a toxin called tetanospasmin. The main characteristic sign of tetanus is a spastic paralysis. A diagnosis is usually based on the clinical signs because the detection in the wound and the cultivation ofC. tetaniis very difficult. Between animal species there is considerable variability in the susceptibility to the bacillus. The most sensitive animal species to the neurotoxin are horses. Sheep and cattle are less sensitive and tetanus in these animal species are less common. Tetanus in cats and dogs are rare and dogs are less sensitive than cats. Clinically two forms of tetanus have been recognized, i. e. localized and generalized. The available treatment is not specific because the toxin in neuronal cells cannot be accessed by antitoxin antibodies. The aim of the therapy is to: neutralise the unbound neurotoxin, inhibitC. tetanigrowth in the wound, and provide supportive care to mitigate the effects of the neurotoxin. The treatment is difficult with an unclear prognosis.
‘Movement as Disclosive of Being’ Merleau-Ponty: From the Psychology of Gestalt to the Analysis of Movement
Authors: Cantone Damiano , Taddio Luca 
Published: October 2020

SummaryIn this essay we seek to clarify the meaning and theoretical implications of the statement by Merleau-Ponty contained in his 1953 course,Le Monde Sensible et le Monde de l’Expression,according to which movement is ‘revealing of being’. This analysis takes up and comments on chapter 7 ofKoffka’s Principles of Gestalt Psychology(dedicated to the issue of movement) and related experiments in particular. We will show that Merleau-Ponty’s idea of ontology of movement emerges from his examination of several exemplary cases. This method of analysis brings to light an idea of similar phenomenology compatible with an experimental phenomenology.

Identifying Scientific and Technical “Unicorns”
Authors: Xu Lucy L. , Qi Miao , Ye Fred Y. 
Published: October 2020

Abstract

Purpose
Using the metaphor of “unicorn,” we identify the scientific papers and technical patents characterized by the informetric feature of very high citations in the first ten years after publishing, which may provide a new pattern to understand very high impact works in science and technology.

Design/methodology/approach
When we set CT as the total citations of papers or patents in the first ten years after publication, with CT≥ 5,000 for scientific “unicorn” and CT≥ 500 for technical “unicorn,” we have an absolute standard for identifying scientific and technical “unicorn” publications.

Findings
We identify 165 scientific “unicorns” in 14,301,875 WoS papers and 224 technical “unicorns” in 13,728,950 DII patents during 2001–2012. About 50% of “unicorns” belong to biomedicine, in which selected cases are individually discussed. The rare “unicorns” increase following linear model, the fitting data show 95% confidence with the RMSE of scientific “unicorn” is 0.2127 while the RMSE of technical “unicorn” is 0.0923.

Research limitations
A “unicorn” is a pure quantitative consideration without concerning its quality, and “potential unicorns” as CT≤5,000 for papers and CT≤500 for patents are left in future studies.

Practical implications
Scientific and technical “unicorns” provide a new pattern to understand high-impact works in science and technology. The “unicorn” pattern supplies a concise approach to identify very high-impact scientific papers and technical patents.

Originality/value
The “unicorn” pattern supplies a concise approach to identify very high impact scientific papers and technical patents.
Sliding mode controller design for second-order unstable processes with dead-time
Authors: Siddiqui Mohammad Atif , Anwar Md Nishat , Laskar Shahedul Haque 
Published: October 2020

Abstract
A new approach is proposed to design the sliding mode (SM) controller for the unstable second-order plus dead-time (SOPDT) processes. The sliding mode control consists of two control laws ie continuous control law and discontinuous control law. The continuous control law parameters have been derived in terms of unstable SOPDT process parameters using the root locus technique. On the other hand, the parameters of discontinuous control law are tuned by optimizing a performance index using a recently developed metaheuristic search algorithm, namely the grasshopper optimization technique. The performance index is framed to achieve a good trade-off between performance and control efforts. Finally, simulations are conducted to validate the effectiveness of the proposed approach over the other existing techniques. It is observed that the proposed approach is able to deliver better disturbance rejection, minimal control efforts and good setpoint tracking.
De-noising of partial discharge signal using wavelet transform for GIS under HVDC
Authors: Wang Guoming , Hu Han , Tang Min , Gong Jinlong , Wang Yifan , Ji Hong-Keun , Kil Gyung-Suk 
Published: October 2020

Abstract
Detection and analysis of partial discharge (PD) have been regard as the most effective method for condition monitoring and asset management of gas-insulated structures (GIS) in the power system. However, PD detection sensitivity and accuracy are greatly influenced by on-site noise and interference, resulting in failures in PD severity assessment, defect identification or localization. Although de-noising of PD signal under AC was well studied, related investigations under DC have not been carried out. With the rapid development of HVDC technology, it is a new challenge to eliminate noise from PD signal under DC for diagnosis of related power facilities. Therefore, this paper dealt with the discrimination of PD signal based on wavelet transform (WT) techniques for HVDC GIS, aiming to improve the sensitivity and accuracy of insulation diagnosis. Experimental setup was configured to generate PD signal under DC and four types of artificial defects were fabricated to simulate typical insulation defects in GIS. The WT techniques were used to discriminate PD pulse sequences from background noise, amplitude modulation radio interference, non-sinusoidal noise, and switching impulse and the effectiveness was compared with a high-pass filter.
Multi-way differential power divider with microstrip output interfaces

Published: October 2020

Abstract
The design and implementation of planar multi-way differential power dividers remain a challenge in terms of the compactness and especially, for the achievable characteristic impedance of the quarter-wavelength transformer when considering large number of outputs. In this work, the double-sided parallel stripline is recommended to realize such a power divider with out-of-phase outputs, and explicit design methods are provided. The proposed multi-way power divider was developed without the use of lump elements on a single substrate. For system applications, a prototype operating at 41.6 MHz with 12 pairs of out-of-phase outputs that utilize the microstrip line as the output interfaces was fabricated and examined. At the center frequency of 41.6MHz, the developed prototype measured insertion losses akin to 14.3 dB as compared with the theoretical data of 13.8 dB. The attainable impedance bandwidth ranges from 10 MHz to 80 MHz under a magnitude imbalance of ±0.3 dB. The isolations of the adjacent outputs are about 13.1 dB as compared with the theoretical values of 14.428 dB, and are better than 34 dB for more distant ones. Parameter measurements are in good agreement with the numerical predications, thus demonstrating the realization of the proposed multi-way power divider.

Mycophenolate for the treatment of primary Sjögren’s syndrome
Authors: Chen Weiqian , Lin Jin 
Published: October 2020

Abstract
Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease with exocrine gland dysfunction and multi-organ involvement. Currently, there is an increasing trend toward non-steroid therapy for the treatment of autoimmune diseases. Some biological agents or immunosuppressive drugs may be the ideal choices. In real-world practice, as patients have severe systemic complications or organ damage, they will have a bad prognosis even if they are treated with high-dose steroids and strong immunosuppressive drugs. However, if we can start early intervention and prevent progressive development in advance, the patient may have a good prognosis. Mycophenolate is an immunosuppressive drug with minor side effects. Here, we conduct a systemic review and find supporting evidence that patients with pSS benefit from early mycophenolate therapy. Mycophenolate may be the first-line treatment for pSS patients in the future.
Composition and changes in the spontaneous flora of the Wadi El Rayan Ramsar site, Fayoum, Egypt, in the last 20 years
Authors: Afefe Abdelwahab A. 
Published: October 2020

AbstractWadi El Rayan is located in Egypt in the Sahara ecoregion the Palearctic ecozone (the world’s largest hot desert). The total area of Wadi El Rayan is 1759km2. The aim of this work was to study the ecosystems, compare species composition, species richness and species diversity of the study sites in the Wadi El Rayan protected area and the distributions of plants in the different landform. The field observations found that there is a low diversity and number of plant species around the lakes, in particular a decline in vegetation cover in accordance with a dramatic decrease in the water level in the lakes compared to earlier studies. The reduction of water levels due to decreased water supply is considered the main threat facing ecosystems and biodiversity in the lake area which requires a continuous survey of flora and measures to be implemented to conserve the natural vegetation in the area. Based on investigations of the spontaneous flora of Wadi El Rayan in 2018, 18 taxa of vascular plants were recorded. This inventory was compared with published records of investigations made in 1998, 2002 and 2014. A total of 18 vascular plant species belonging to 14 families were recorded in the wetland and desert ecosystems around the lakes of Wadi El Rayan. The vegetation mainly consists of sparsely distributed xerophytic and halophytic plants except in the wetland ecosystem around the lakes where it is characterized by some hydrophytic and halophytic plants. The family with the highest number of species was Poaceae followed by Zygophyllaceae. The results showed that a higher number of species was recorded from the Lower Lake (13 species) than the Upper Lake (10 species) and (5 species) for the connecting channel. The most frequently recorded species werePhragmites australis, Tamarix nilotica, Juncus rigidusandAlhagi graecorum: the first two species were the most successful species as they grow in a variety of ecosystems and habitats.
