Published: August 2020

O grande número de publicações contendo dados experimentais sobre manifestações patológicas que podem ocorrer em elementos de construção torna o trabalho dos pesquisadores cada vez mais complexo e extenso no que se refere à seleção de material bibliográfico para o embasamento da pesquisa. Dentre as manifestações patológicas mais importantes e recorrentes, o fenômeno de retração se destaca por influenciar na durabilidade das argamassas de revestimento. Dentre os tipos de retração existentes, a retração plástica e de secagem representam grande parcela da retração total das argamassas de revestimento. Dessa forma, foi realizada uma revisão bibliográfica com os temas retração de secagem e retração plástica em argamassas de revestimento, dos últimos 5 anos, utilizando os procedimentos do método MethodiOrdinatio para avaliar a atual conjuntura das pesquisas nesse tema. Através da revisão foram identificados 1932 artigos, dos quais, 26 foram selecionados para discussão do artigo, considerando os critérios de exclusão do método MethodiOrdinatio. Foi observado um aumento do número de pesquisas relacionadas à retração no ano de 2018. Portugal aparece como líder no ranking de número de publicação por países. Apesar do crescente número de publicações, é notável a disparidade na quantidade de pesquisas entre os dois tipos de retração, sendo a grande maioria formada por retração por secagem. Além disso, estudos relacionados à retração plástica se mostraram menos relevantes no âmbito científico, aparecendo apenas em 12º lugar no ranking de relevância, o que não condiz com a importância desse tipo de retração nas características do estado plástico e endurecido do material. Dessa forma, é de suma importância o preenchimento das lacunas de conhecimento existente e formulação de ensaios capazes de avaliar a retração do material no estado plástico.
Reprovisioning for latency-aware dynamic service chaining in metro networks
Authors: Askari Leila , Musumeci Francesco , Tornatore Massimo 
Published: August 2020

To support newly emerging and highly dynamic 5G services, optical metro networks must be capable of provisioning services on the fly. Network function virtualization (NFV) is leveraged to fulfill these dynamic service demands by placing virtual network functions (VNFs) in NFV-capable network nodes and chaining them together (“service chaining”). In addition, new 5G service chains often have bandwidth requirements with subwavelength granularity, making traffic grooming essential for efficient network resource utilization. However, the latency requirement for these services will not allow one to always perform traffic grooming, as grooming operations add non-negligible latency to traffic, and this might lead to poor utilization and high service blocking. Thus, it is important to investigate dynamic solutions to increase network utilization and decrease service blocking. One approach to achieve this goal is to reprovision service chains (SCs) to use network resources as efficiently as possible. Reprovisioning consists of tearing down a service chain and reallocating its resources, typically with the intent to make room for new chains that would be otherwise rejected. While traditional reprovisioning entailed only routing reassignment, reprovisioning of SCs entails both rerouting traffic and/or relocating VNFs, hence originating new research problems. In this paper, we propose new heuristic algorithms to reprovision SCs whenever a service cannot be provisioned. We provide two different approaches to perform reprovisioning, i.e., bandwidth and location. While bandwidth reprovisioning consists of modifying only bandwidth assignment of SCs, location reprovisioning considers the possibility of changing the nodes each SC is mapped to. We also considered two different optical network architectures. Results obtained on realistic network topology and services show that location reprovisioning allows us to achieve up to 28% improvement in terms of the number of SCs we are able to provision in the network.
Paraphernalia of Funerary Display at Kaneš
Authors: Heffron Yağmur 
Published: August 2020

AbstractThe Hittite royal funerary ritual šalliš waštaiš prescribes gold pieces to be placed on the eyes and mouth of the deceased. This is consistent with the manner in which thin sheets of hammered gold are reported to have been found on the faces of occupants of in-house graves in the Lower Town of Kültepe, ancient Kaneš. Mouth-pieces of unmistakable similarity have also turned up in great numbers in Late Bronze Age graves on Cyprus, most notably at Enkomi. Beyond comparison with the šalliš waštaiš text, gold eye- and mouth-pieces from Kaneš have received little attention. This contribution offers the first comprehensive study of these objects specifically as a class of funerary paraphernalia. It provides a catalogue and typology of gold sheets, and explores their archaeological context before turning to their social and symbolic significance against the backdrop of the cosmopolitan Kanešean households. The discussion considers hybridity in terms of a compatibility between funerary practices across different cultural settings, also noting chronological implications.

Published: August 2020

AbstractThe aim of this study was to simulate olive oil use and to monitor changes in the profile of fatty acids in home-made preparations using olive oil, which involve repeated heat treatment cycles. The material used in the experiment consisted of extra virgin and refined olive oil samples. Fatty acid profiles of olive oil samples were monitored after each heating cycle (10 min). The outcomes showed that cycles of heat treatment cause significant (p< 0.05) differences in the fatty acid profile of olive oil. A similar trend of differences (p< 0.05) was found between fatty acid profiles in extra virgin and refined olive oils. As expected, the main differences occurred in monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs). Cross-correlation analysis also showed differences between the fatty acid profiles. The most prolific changes were observed between the control samples and the heated (at 180°C) samples of refined olive oil in PUFAs, though a heating temperature of 220°C resulted in similar decrease in MUFAs and PUFAs, in both extra virgin and refined olive oil samples. The study showed differences in fatty acid profiles that can occur during the culinary heating of olive oil. Furthermore, the study indicated that culinary heating of extra virgin olive oil produced results similar to those of the refined olive oil heating at a lower temperature below 180°C.
A new adaptive XOR, hashing and encryption-based authentication protocol for secure transmission of the medical data in Internet of Things (IoT)
Authors: Chaudhari Dipalee Ashok , Umamaheswari Ekambaram 
Published: August 2020

Abstract
Internet of Things (IoT) plays a prominent role in health-care of patients, which assist the physicians and patients through the assistance in effective decision-making and additionally, in the medical field, IoT plays a significant role in real-time monitoring of the patients. Even though the data provided by the IoT devices ensure the effective decision-making, the data is susceptible to the network attacks. Thus, the paper proposes an authentication protocol for enabling the secure data transmission in IoT based on three functions, such as encryption function, hashing function, and adaptive XOR function. The proposed authentication protocol is named as, Adaptive XOR, hashing and Encryption Key Exchange (AXHE) protocol, which is the combination of the functions, such as encryption function, hashing function, and adaptive XOR function. The protocol ensures the security in the communication through two successive phases, such as registration and authentication of the user, where the user name, password, public keys, private keys, and security factor are employed. The authentication is progressed as seven levels and whenever the security factor matches, the user is authenticated and the communication continues. The analysis of the proposed AXHE is performed using 50 and 100 nodes in the presence of DOS and black hole attacks, which acquires the detection rate, throughput, and detection delay of 0.3859, 0.32, and 6.535 s, respectively.
Reassessment of Tristan da Cunha Gelidium (Gelidiales, Rhodophyta) species
Authors: Freshwater D. Wilson , Scott Sue , Tronchin Enrico M. , Saunders Gary W. 
Published: August 2020

Abstract
Three endemic species of Gelidium have been described from the remote Tristan da Cunha archipelago. A recent barcode survey of Tristan da Cunha red algae in combination with the clarification of vouchers for previously sequenced specimens has prompted a molecular and morphological reassessment of these species. Analyses of rbcL and COI-5P data indicated that all sequenced Tristan da Cunha specimens represented a single taxon, and furthermore that this genetic group was conspecific with Gelidium micropterum from southern Africa. Morphologically the Tristan da Cunha specimens represented either Gelidium concinnum or Gelidium regulare, and there was a grade of character states between both of these species, as well as G. micropterum. Based on these results the synonymy of G. concinnum and G. regulare under G. micropterum is proposed and an expanded description of G. micropterum provided. None of the studied Tristan da Cunha specimens clearly fit the description of the third endemic species, Gelidium inflexum, and its status could not be determined.

Abstract

Objectives
Assessment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection prevalence and immunity is cornerstones in the fight against COVID-19 pandemic. For pandemic control, reliable assays for the detection of anti-SARS-CoV-2 antibodies are required. This pilot external quality assessment (EQA) scheme aimed to independently assess the participants’ clinical performance of anti-SARS-CoV-2 testing, to identify shortcomings in clinical practice and to evaluate the suitability of the scheme format.

Methods
The EQA scheme consisted of eight serum samples with variable reactivity against SARS-CoV-2 intended for the analysis of anti-SARS-CoV-2 immunoglobulin (Ig)G, IgA, and IgM antibodies. Laboratories reported: (1) results for each sample and the respective method, (2) raw data from replicate testing of each sample.

Results
The 16 selected pilot EQA participants reported 294 interpreted results and 796 raw data results from replicate testing. The overall error rate for the anti-SARS-CoV-2 IgG, IgA, and IgM tests was 2.7, 6.9, and 16.7%, respectively. While the overall diagnostic specificity was rated as very high, sensitivity rates between 67 and 98% indicate considerable quality differences between the manufacturers, especially for IgA and IgM.

Conclusions
Even the results reported by the small number of participants indicate a very heterogeneous landscape of anti-SARS-CoV-2 serological testing. Differences of available tests and the individual performance of laboratories result in a success rate of 57.1% with one laboratory succeeding for all three antibody-classes. These results are an incentive for laboratories to participate in upcoming open EQA schemes that are needed to achieve a harmonization of test results and to improve serological testing.

Abstract
Nowadays, biodiesel is promoted as an alternative and renewable fuel. The mass-transfer limited transesterification reaction is commonly used for biodiesel production, but it could benefit from process intensification technologies. The Simultaneous Mixer-Separator (SMS) is a novel process intensification reactor capable of integrating the mixing and separation of reactants within a single unit. The current study aims to determine the ideal parameters for continuous biodiesel production using an SMS setup that was exclusively designed and fabricated in-home for enhanced biodiesel production. The research statistically analyzed the effect of the space between the rotor and the bottom of reactor (h) (0.7, 1.0, 1.3 cm), the diameter ratio between the rotor and the stator (Dr/Ds) (0.5, 0.7, 0.9), and the frequency of the rotor’s rotary speed (R

Authors: Montenegro del Moral María , Isabel González Villa , Padilla Pérez Ana I. , Alvarez-de-la-Rosa Rodríguez Margarita 
Published: August 2020

Abstract

Objectives
We aim to report a case of a septated urinary bladder with kidney dysplasia in a fetus presenting with 2q13 microdeletion. Several genes have been related to urogenital malformations. Reports of fetal multi-septated urinary bladder are extremely rare. Deletion 2q13 is responsible for a wide range of phenotypic manifestations but not commonly urogenital diseases.

Case presentation
We present a case of a primigravida with no contributing history referred to our center for suspected fetal kidney dysplasia. Ultrasound scan at 25 weeks gestation revealed septated urinary bladder and severe pelvic renal dilatation. CGH array showed de novo deletion 2q13. Upon counseling the parents opted for termination. Autopsy confirmed the urinary tract findings and normal external female genitalia.

Conclusions
To the best of our knowledge this is the first report of a 2q13 microdeletion and septated bladder. We suggest offering genetic counseling at the finding of a septated bladder and determine prognosis upon renal parenchymal destruction.
Translation Semiotics: The Disciplinary Essence
Authors: Wang Mingyu , Li Jing 
Published: August 2020

Abstract
Translation semiotics studies the transformation of signs in translation, which generally involves semiosis, sign behavior, sign relations, semiotic hierarchy, intersemiosis, semiotic function, and semiotic conservation. This paper attempts to explore, from these seven dimensions, the disciplinary essence of TS and foresees the development of this burgeoning discipline as a branch of semiotics.
Hegels negative Dialektik
Authors: Gelhard Andreas 
Published: August 2020

AbstractHegel’s approach to ancient scepticism is often discussed only in the context of epistemological questions. But it is also of crucial importance for his practical philosophy. Hegel draws on central figures of Pyrrhonian scepticism in order to subject Kant’s antinomies – i. e., Kant’s cosmology – to a fundamental revision. He radicalises Kant’s sceptical method to “self-completing scepticism”. At the same time he gives Kant’s concept of the world a practical twist: In Hegel’sPhenomenology of Spirit, world means an inhabited sphere in which powers and counter-powers are in conflict with each other. In doing so, he opens up the tradition of negativist thinking in political philosophy, which ranges from Marx and Adorno to the current theories of radical democracy. When Hegel calls Pyrrhonian skepticism a “negative dialectic”, he thereby marks what he views as a deficit: the inferiority of Pyrrhonian skepticism to speculative philosophy. However, it is precisely the practical dimension of Hegel’s dialectic that suggests that the sceptical motives of his thinking should be given great weight. This can be seen most clearly in Hegel’s concept ofBildung, which defines emancipation processes as the reactivation of open power relations in static conditions of domination.
Was heißt Gestalt? – für eine morphologische Designphilosophie
Authors: Arnold Florian 
Published: August 2020

Abstract
The paper proposes a morphological approach towards a philosophy of design. Beginning with the question: what is “Gestalt”? it argues that there is a crucial difference between the concepts of “Gestalt” and “form”. I will proceed in three steps, beginning with the Aristotelian doctrine of the four causes and its implications for the concept of nature. Secondly I will briefly discuss Goethe’s notion of “Gestalt” within his “Morphologie” and how it was used among his successors (including the “Bauhaus”), which leads straight into contemporary debates about computational design. Finally, and in conclusion, I introduce a morpho-logical “Gestalt”-thinking as a distinct and original kind of design-philosophy, beyond common design-history, or mere design-thinking.
Entrepreneurial Action and Competencies: Exploring Pathways to Venturing Accomplishments
Authors: Botha Melodi , Pietersen Michael 
Published: August 2020

Abstract
Scholars often cite an entrepreneur’s actions and their skills, know-how and entrepreneurial competencies (ECs) as the most influential factors related to the accomplishment of important venturing outcomes. Yet the joint impact of these factors on venturing accomplishments is yet to be explored. This paper aims to fill this void by empirically developing and testing a mediation model exploring three EC mechanisms by which entrepreneurial actions—specifically discovery and exploitation activities—led to the achievement of specific venturing accomplishments—namely the time to breakeven and turnover achieved. Data were collected from 1150 South African entrepreneurs using an online survey. Covariance-based structural equation modeling was used to test the hypothesized model. Results show that entrepreneurial action (EA) significantly impacts on the efficiency and effectiveness of a venture through the development of three key ECs. Furthermore, the type of action taken by entrepreneurs during the entrepreneurial process differentially influences competency development and venturing accomplishments. More specifically, opportunity discovery and exploitation activities have a varying impact on EC development, as the engagement in these distinct venture-related activities provides unique feedback for the development of appropriate behavioral scripts for specific contexts which lead to distinct venturing accomplishments. This research offers novel insights into the newly emerging scholarly conviction that engagement in the entrepreneurial process itself may affect key entrepreneurial abilities and accomplishments. In so doing, this paper builds on, and has implications for, theories of competency development and venturing performance, as well as pedagogical interventions aimed at enhancing entrepreneurship.
Strata behavior and control strategy of backfilling collaborate with caving fully-mechanized mining
Authors: Wei Yin , Jiaqi Wang , Xiaomin Bai , Wenjie Sun , Zheyuan Zhou 
Published: August 2020

Abstract
This article analyzes the technical difficulties in full-section backfill mining and briefly introduces the technical principle and advantages of backfilling combined with caving fully mechanized mining (BCCFM). To reveal the strata behavior law of the BCCFM workface, this work establishes a three-dimensional numerical model and designs a simulation method by dynamically updating the modulus parameter of the filling body. By the analysis of numerical simulation, the following conclusions about strata behavior of the BCCFM workface were drawn. (1) The strata behavior of the BCCFM workface shows significant nonsymmetrical characteristics, and the pressure in the caving section is higher than that in the backfilling section. φ has the greatest influence on the backfilling section and the least influence on the caving section. C has a significant influence on the range of abutment pressure in the backfilling section. (2) There exits the transition area with strong mine pressure of the BCCFM workface. φ and C have significant effect on the degree of pressure concentration but little effect on the influence range of strong mine pressure in the transition area. (3) Under different conditions, the influence range of strong mine pressure is all less than 6 m. This article puts forward a control strategy of mine pressure in the transition area, which is appropriately improving the strength of the transition hydraulic support within the influence range (6 m) in the transition area according to the pressure concentration coefficient. The field measurement value of Ji15-31010 workface was consistent with numerical simulation, which verifies the reliability of control strategy of the BCCFM workface.

AbstractAdministrative detention has gradually become a fundamental instrument in migration policies of European States. The law generally assigns to this measure a key role in supporting removal procedure. On the other hand, administrative detention has been recognised as a symptom of the crimmigration crisis. This article aims to challenge the expected benefits of administrative detention as an effective measure to guarantee the enforcement of removal procedures, analysing available data of imprisonments and removals relative to Italy, France, Spain and Greece in the period of time 2014–2019.
Rapid and nondestructive evaluation of hygroscopic behavior changes of thermally modified softwood and hardwood samples using near-infrared hyperspectral imaging (NIR-HSI)
Authors: Ma Te , Schimleck Laurence , Inagaki Tetsuya , Tsuchikawa Satoru 
Published: August 2020

Abstract
The objective of this work was to provide a rapid and nondestructive imaging method for evaluating the hygroscopic behavior of thermally modified lignocellulosic materials (softwood and hardwood). The difference in the hygroscopic behavior was explained by moisture content (MC) mapping results and molecular association characteristics of absorbed water (i.e. weakly, moderately, and strongly hydrogen-bonded water molecules) with wood at various relative humidities (RH). To achieve this goal, near-infrared (NIR) spectral images in the wavelength range 1816–2130 nm (covering the combination of stretching and deformation vibrations for OH) were used to visualize MC distributions over the surface of Japanese cedar and European beech samples which had been thermally treated at different temperatures. A curve fitting method was utilized to explore changes in water-wood structure characteristics based on shifts to longer wavelength in spectral signals caused by increasing MC. The curve fitting results support the recent nuclear magnetic resonance (NMR) studies that different bound water stabilities may pool in different compartments of the wood cell wall. Furthermore, water was firmly bound to wood at low RHs and H-bonds gained mobility as the number of absorbed molecules increased. It is concluded that NIR hyperspectral imaging also has the potential to be a complementary methodology for studying the transient changes of wood-water interactions before equilibrium.
