Second-Order Liminality: Dynamics of Ritual Change in the Basel Fasnacht
Authors: Cieslarová Olga , Chlup Radek
Published: November 2020

Taking the example of the Basel carnival Fasnacht, the paper shows in what way ritual can maintain the impression of being traditional and unchanging, and yet be open to changes and innovations. As the basic conceptual framework we use the notion of liminality, which Victor Turner identified as the creative moment of ritual. In Fasnacht, this liminal dimension appears in two degrees. The carnival as such represents a reflexive liminal counterpart to the standard social structure, yet it is itself also highly structured and bound by conservative traditional rules. As a reaction to this, there arises within Fasnacht a second-order liminality in the form of the so-called wild Fasnacht, which turns the official antistructural Fasnacht rules upside down once again, testing their validity. While the carnival structure offers a regulated opportunity for questioning everyday social behaviour, wild Fasnacht questions even this regulated manner of questioning as such, opening space for its reflection and modification. We use detailed examples to demonstrate how the subtle dialectics of structure and antistructure keeps the tradition of Basel’s Fasnacht alive and allows it to evolve without destroying its aura of traditionality.
Soliton turbulence in electronegative plasma due to head-on collision of multi solitons
Authors: Ali Rustam , Sharma Anjali , Chatterjee Prasanta
Published: November 2020

Head-on interaction of four dust ion acoustic (DIA) solitons and the statistical properties of the wave field due to head-on interaction of solitons moving in opposite direction is studied in the framework of two Korteweg de Vries (KdV) equations. The extended Poincaré–Lighthill–Kuo (PLK) method is applied to obtain two opposite moving KdV equations from an unmagnetized four component plasma model consisting of Maxwellian negative ions, cold mobile positive ions, κ-distributed electrons and positively charged dust grains. Hirota’s bilinear method is adopted to obtain two-soliton solutions of both the KdV equations and accordingly act of soliton turbulence is presented due to head-on collision of four solitons. The amplitude and shape of the resultant wave profile at the point of strongest interaction are obtained. To see the effect of head-on collision on the statistical properties of wave field the first four moments are computed. It is observed that the head-on collision has no effect on the first integral moment while the second, third and fourth moments increase in the dominant interaction region of four solitons, which is a clean indication of soliton turbulence.
Octonions, trace dynamics and noncommutative geometry—A case for unification in spontaneous quantum gravity
Authors: Singh Tejinder P.
Published: November 2020

We have recently proposed a new matrix dynamics at the Planck scale, building on the theory of trace dynamics and Connes noncommutative geometry program. This is a Lagrangian dynamics in which the matrix degrees of freedom are made from Grassmann numbers, and the Lagrangian is trace of a matrix polynomial. Matrices made from even grade elements of the Grassmann algebra are called bosonic, and those made from odd grade elements are called fermionic—together they describe an ‘aikyon’. The Lagrangian of the theory is invariant under global unitary transformations and describes gravity and Yang–Mills fields coupled to fermions. In the present article, we provide a basic definition of spin angular momentum in this matrix dynamics and introduce a bosonic(fermionic) configuration variable conjugate to the spin of a boson(fermion). We then show that at energies below Planck scale, where the matrix dynamics reduces to quantum theory, fermions have half-integer spin (in multiples of Planck’s constant), and bosons have integral spin. We also show that this definition of spin agrees with the conventional understanding of spin in relativistic quantum mechanics. Consequently, we obtain an elementary proof for the spin-statistics connection. We then motivate why an octonionic space is the natural space in which an aikyon evolves. The group of automorphisms in this space is the exceptional Lie group G
2 which has 14 generators [could they stand for the 12 vector bosons and two degrees of freedom of the graviton?]. The aikyon also resembles a closed string, and it has been suggested in the literature that 10-D string theory can be represented as a 2-D string in the 8-D octonionic space. From the work of Cohl Furey and others it is known that the Dixon algebra made from the four division algebras [real numbers, complex numbers, quaternions and octonions] can possibly describe the symmetries of the standard model. In the present paper we outline how in our work the Dixon algebra arises naturally and could lead to a unification of gravity with the standard model. From this matrix dynamics, local quantum field theory arises as a low energy limit of this Planck scale dynamics of aikyons, and classical general relativity arises as a consequence of spontaneous localisation of a large number of entangled aikyons. We propose that classical curved space–time and Yang–Mills fields arise from an effective gauging which results from the collection of symmetry groups of the spontaneously localised fermions. Our work suggests that we live in an eight-dimensional octonionic universe, four of these dimensions constitute space–time and the other four constitute the octonionic internal directions on which the standard model forces live.

In both structure types, the transition metal and aluminum atoms form a complex polyanionic network with the cerium atoms filling the respective cavities. The transition metal atoms are in both cases surrounded in the shape of a tri-capped trigonal prism, the connectivity of these units, however, is different. Temperature-dependent magnetic susceptibility measurements of all compounds indicated a stable trivalent oxidation state for the cerium atoms along with antiferromagnetic ordering around T

Published: November 2020

Synthesis, crystal structure and temperature-dependent behavior of Na2H4Ga2GeO8 are reported. This novel gallogermanate crystallizes in space group I41/acd with room-temperature powder diffraction lattice parameters of a = 1298.05(1) pm and c = 870.66(1) pm. The structure consists of MO4 (M = Ga, Ge) tetrahedra in four-ring chains, which are connected by two different (left- and right-handed) helical chains of NaO6 octahedra. Protons coordinating the oxygen atoms of the GaO4 tetrahedra not linked to germanium atoms ensure the charge balance. Structure solution and refinement are based on single crystal X-ray diffraction measurements. Proton positions are estimated using a combined approach of DFT calculations and NMR, FTIR and Raman spectroscopic techniques. The thermal expansion was examined in the range between T = 20(2) K and the compound’s decomposition temperature at 568(5) K, in which no phase transition could be observed, and Debye temperatures of 266(11) and 1566(65) K were determined for the volume expansion.

The fall armyworm, Spodoptera frugiperda, is a polyphagous pest that causes important damage in different regions of America and mainly affects corn crops in both tropical and subtropical areas. Currently, control relies on both transgenic plants and/or chemical pesticides. In this work, we describe insecticidal activity against the fall armyworm from a series of Mannich bases (1–10), derived from 2-hydroxy-1,4-naphthoquinone (lawsone), substituted benzaldehydes, and two primary amines, and their Cu2+ complexes (11–20). The [Cu(L)2] complexes were more effective in larval mortality compared to the free Mannich bases. Among the tested compounds, complex 11 showed the highest toxicity, with 70.00% larval mortality.

Published: November 2020

In the present investigation, ZnO, CuO and Fe2O3 were prepared via green route and utilized for the sequestration of DGY (Direct Golden Yellow) dye. Affecting variables i.e., temperature, contact time, adsorbent dose and pH were optimized for maximum sequestration of dye from aqueous medium. The pH 2, adsorbent dose 0.1 g/50 mL dye solution, temperature 30 °C and 50 mg/L dye initial concentration were best levels for efficient dye adsorption and equilibrium was attained in 30 min reaction time. The dye sequestration on to ZnO, CuO and Fe2O3 was an exothermic process. Freundlich and Temkin adsorption isotherms explained well the dye adsorption onto nanoadsorbents and dye adsorption followed pseudo first order kinetic model. Effect of electrolytes and heavy metal ions was also investigated and both affected the adsorption process significantly. In the presences of surfactant/detergent, the removal of dye was reduced and 0.5 N NaOH efficiently desorbed the dye from nanoadsorbents. Findings depicted that the nanoadsorbents are effectual for the sequestration of DGY dye, which can be employed for the remediation of textile effluents.

Authors: Monico Carmen , Kupatadze Ketevan
Published: November 2020

The student co-teacher and co-mentor model introduced in this article seeks to promote learning, reflection, and critical thinking and to nurture students’ intellectual curiosity through high academic standards and experiential learning, including community engagement and study abroad. Similarly, scholarship of teaching and learning research on pedagogical partnerships demonstrates improved learning, self-awareness, and engagement with the educational material as a result of students’ partnership and collaboration with faculty and staff. Limited existing research combines the student-faculty partnership model with the development of students’ intercultural competencies in experiential learning contexts, such as practicums, internships, and study abroad. This article focuses on approaches to engaging Elon University students as partners in a practicum course in Guatemala. The study provides evidence of the model fitness as well as the potential for replication of higher education approaches, such as the emerging global learning model for practicum instruction.
Students with disabilities as partners: A case study on user testing an accessibility website
Authors: Brown Kate , De Bie Alise , Aggarwal Akshay , Joslin Ryan , Williams-Habibi Sarah , Sivanesanathan Vipusaayini
Published: November 2020

While partnership is widely encouraged as an approach to advancing the inclusion of disabled postsecondary students, these collaborations are largely taking place between staff offices and failing to meaningfully integrate disabled students as partners. In this case study, we describe the successes and challenges of a pilot project where students and staff with and without disabilities worked together to user test our university’s accessibility website, to which faculty/staff are regularly directed for resources on making their teaching more accessible. We achieved our goal of compiling results into a report for decision-makers in order to advance campus-wide technological accessibility. Instead of primarily treating disabled students as lacking capacities and requiring programmatic intervention to succeed in the university, a partnership approach validates and draws on disabled students’ specific expertise and experience to make institutional change.

This case study draws on the concept of open pedagogy (Paquette, 1979; DeRosa & Jhangiani, 2018) to frame a student-faculty partnership project focused on creating videos about education technology. Four student research assistants were full partners and creators within this project, developing models and parameters for future contributions by both faculty members and fellow students. All partners contributed as creators, collaborators, and coordinators for aspects of the project. The case study explores how open pedagogy can be a meaningful foundation for Students-as-Partners (SaP) collaborations.
EFFECT OF TRANSGLUTAMINASE ON QUALITY ATTRIBUTES OF NOODLE ENRICHED WITH GERMINATED MUNG BEAN FLOUR
Authors: YAVER Elif , BİLGİÇLİ Nermin
Published: November 2020

Germination is an effective process improving nutritional status of cereal and legume. This study evaluates the effect of germinated mung bean flour (GMF) (0-20%) on physical, chemical properties and cooking quality of egg noodles, as well as the impact of transglutaminase (TGase) on the physical properties and cooking quality of GMF noodles. Compared to raw mung bean flour, GMF showed higher total phenolic content, antioxidant activity, total-extractable ash, Ca, Fe, K, P and Zn content with lower phytic acid. As the GMF ratio increased, cooking loss values also increased. TGase developed cooking quality with decreasing cooking loss and improving firmness. Noodles made with 20% of GMF revealed the highest total ash, HCl-extractable ash, protein, phytic acid, antioxidant activity and total phenolic content. This study shows the potential of GMF (up to 15%) and TGase to produce noodles with high nutritive value and good consumer acceptability.
Water Infrastructure and Practical Knowledge in Progressive-Era Los Angeles
Authors: Hansen Jan
Published: November 2020

This article proposes that a history-of-knowledge approach offers innovative ways to study the use of domestic infrastructure in the household. More specifically, the article investigates the role of knowledge about water fixtures, such as meters, taps, and toilets, in the history of progressive-era Los Angeles. Building on the rich literature about how Los Angeles obtained its water, this article shifts the focus to the relationship that everyday consumers had with their water and how technology mediated this relationship. While the article analyzes three major fields of knowledge about the use of infrastructure (knowledge about personal and public hygiene, about the maintenance and repair of fittings, and about responsible levels of water consumption), it foregrounds users’ agency in construing bodies of knowledge. Taken together, this article argues, first, that practical knowledge about water as a modern convenience was mutually developed by the utility’s publicity department, meter men, municipal health authorities, elected officials, newspaper editors, middle-class reformers, property owners, working-class immigrants, and female householders. Second, the article emphasizes the dynamics, contingency, and locality of this knowledge, which was linked to the stunning growth of Los Angeles between 1880 and 1930.

Damage to the nervous system, in particular spinal cord injuries, is a burden for the patient and is usually the cause of irreversible disability. The progress observed in the last decade in the fields of biology, biomaterial engineering and neurosurgery has created new treatment solutions while preventing further neurodegenerative processes. The most important research is focused on the implementation of polymer structures in clinical practice, especially chitosan hydrogels, which are the scaffolds for regenerating axons. This article presents a new generation of biomaterials that have the ability to gel in response to temperature changes; they are intended for injectable scaffolds for nerve cell cultures. Two types of hydrogels were prepared based on chitosan lactate and chitosan chloride using uridine 5’-monophosphate disodium salt. The structure of the systems was observed under a scanning electron microscope and examined using Fourier transform infrared spectroscopy. In addition,
thermal properties were tested using differential scanning calorimetry.

Transformasi Wavelet dengan Teknik Clipping Filtering untuk Mereduksi PAPR pada OFDM
Authors: Wirastuti Ni Made Ary Esta Dewi , Dhyaksa Ida Bagus Dharma
Published: November 2020

Orthogonal Frequency Division Multiplexing (OFDM) is chosen as multiplexing techniques and broadly used in today’s radiocommunication environments to overcome spectrum insufficiency. With several superior advantages, however, OFDM is terribly affected by high peak to average power ratio (PAPR) due to offset frequency errors and local oscillator (LO) frequency synchronization errors. The high PAPR can cause nonlinear distortion, which outcomes in intermodulation and spectral leakage. This study aims to model the use of wavelet transform (discrete wavelet transform (DWT)) to replace Fourier transform (discrete Fourier transform (DFT)) that used in conventional OFDM, later in this paper is termed as DFT-OFDM. Clipping filtering techniques then applied to DWT-OFDM. The model was proposed to reduce PAPR in DFT-OFDM. The model was compared to DFT-OFDM using Matlab simulation method. The performance was evaluated using the Complementary Cumulative Distributive Function (CCDF) vs. PAPR. The results show that at PAPR 10-3for DFT-OFDM, it was produced PAPR of 10.6 dB whereas in DWT-OFDM, using Daubechies orde 7 (Daubechies7),  Symlet orde 7 (Symlet7), Coiflet orde 2 (Coiflet2), were reached PAPR 4.8 dB, PAPR 3.3 dB, PAPR 3 dB, respectively. It means Coiflet2 providing the best PAPR reduction among other orthogonal wavelets. By applied clipping filtering to wavelet Coiflet2, it was produced PAPR of 2.9 dB for classical clipping and 2.8 dB for deep clipping. It show that wavelet Coiflet2 with deep clipping provided the best PAPR.

The Interchromosomal Effect: Different Meanings for Different Organisms
Authors: Miller Danny E
Published: November 2020

The term interchromosomal effect was originally used to describe a change in the distribution of exchange in the presence of an inversion. First characterized in the 1920s by early Drosophila researchers, it has been observed in multiple organisms. Nearly half a century later, the term began to appear in the human genetics literature to describe the hypothesis that parental chromosome differences, such as translocations or inversions, may increase the frequency of meiotic chromosome nondisjunction. Although it remains unclear if chromosome aberrations truly affect the segregation of structurally normal chromosomes in humans, the use of the term interchromosomal effect in this context persists. This article explores the history of the use of the term interchromosomal effect and discusses how chromosomes with structural aberrations are segregated during meiosis.

La gestión pública de una obra hidráulica compleja, entre el marco internacional y los intereses regionales privados: el caso del trasvase Tajo-Segura (España)
Authors: Escudero Gómez Luis Alfonso , Martín Trigo Alejandro
Published: November 2020

Los procesos económicos globales han agravado los problemas, conflictos y tensiones derivados del uso del agua dulce a escala global, estatal, regional y local. En la época contemporánea, la aceleración derivada de la industrialización y la urbanización ha aumentado el consumo del agua y las infraestructuras artificiales para su utilización. Hoy, el capitalismo de mercado global se ha ido apropiando de los recursos naturales y en el uso del agua predominan los intereses privados.
Al mismo tiempo, la degradación medioambiental obliga a intentar compatibilizar el consumo humano y económico con el respeto hacia la naturaleza. En la legislación vigente, en áreas como la Unión Europea, ya se da prioridad a la conservación del medio ambiente sobre la utilización incontrolada del agua como recurso productivo, sobre todo a partir de la aprobación de la Directiva Marco del Agua en 2000. Sin embargo, la política hidráulica española se ha centrado en el agua como bien económico. Con esta premisa se construyeron infraestructuras como el trasvase Tajo-Segura.
Actualmente, España, como miembro de la UE, debe adaptarse a la DMA y esto genera un tensa relación internacional-nacional-regional por la gestión pública del trasvase. El artículo se centra en esta cuestión. Se aplicará una metodología deductiva y basada en un análisis teórico crítico a partir del estudio bibliográfico y de la normativa vigente, del apoyo en datos cuantitativos y de las reflexiones de los autores.
Se concluye que el trasvase no se ajusta a la sostenibilidad ambiental y ecológica que proclama la DMA, sino que sigue respondiendo a la necesidad de satisfacer la demanda de la cuenca receptora. Además, en periodos de sequía se permite el mercado de cesión de agua de la cuenca cedente a la receptora entre particulares, ignorando el impacto ecológico derivado y superponiendo los intereses económicos. La prioridad debería ser satisfacer la demanda de agua dulce como necesidad de abastecimiento para toda la población y evitar los impactos al medio ambiente. Sin embargo, es evidente que las autoridades públicas están principalmente preocupadas por satisfacer las demandas de agua que tienen que ver con la producción económica aun a sabiendas de no cumplir plenamente con la legislación europea. La contribución resultará de interés a nivel científico y social y se une al debate actual en torno a las políticas de agua dulce en las dinámicas globales.

Intervención de caminata para empleados sedentarios: efecto sobre la autorregulación y la auto eficacia
Authors: Rodríguez-Hernández Mynor G. , Wadsworth Danielle
Published: November 2020

Se diseñó una intervención de caminata de 10 semanas para examinar cómo la actividad física afecta la autorregulación y la autoeficacia en empleados sedentarios. La intervención fue realizada con 68 participantes, asignados a tres grupos al azar: caminata intermitente, caminata continua o control. La autorregulación, la autoeficacia y la actividad física se midieron al inicio, en la semana 6 y en la semana 11. La actividad de caminata aumentó significativamente (p < .05) con el grupo de caminata continua desde el inicio a la semana 6 (p = .033). El porcentaje de cambio fue mayor en comparación con el grupo control desde el inicio a la semana 11 (p = .042). Se observaron mejoras significativas en la autorregulación con el grupo de caminata continua desde el inicio a la semana 6 y a la semana 11 (p < .05). Sin embargo, la autoeficacia disminuyó desde el inicio a la semana 6 (p = .047) y a la semana 11 (p = .008) para todos los grupos. Los empleados sedentarios tendrían más ventajas si se les prescribe un programa de caminata continua, ya que puede mejorar las habilidades de autorregulación. La actividad de caminata intermitente también puede ser un enfoque factible para reducir el comportamiento sedentario; sin embargo, se necesita más investigación para evaluar si los empleados sedentarios pueden o no cumplir con las recomendaciones diarias de actividad física. También es importante revisar en futuras investigaciones el vínculo entre la actividad física y la autoeficacia.

Three electrosurgical tissue-sealing devices (EnSeal ETSDRC-01, LigaSure LS1500 and Thunderbeat TB-0535PC) were compared regarding sealing time (ST), maximum working temperature (WTmax) and the total (MTZtotal) as well as the collateral microscopic thermal injury zone (MTZcollat) using laparoscopic handpieces 5 mm in diameter on four types of tissue (liver, mesentery, cross striated muscle and spleen) in an in vivo porcine model. LigaSure had the lowest mean ST in spleen, mesentery, muscle and liver, followed by Thunderbeat and EnSeal with significant differences between all types of tissues and devices. The significantly lowest mean WTmax was obtained for EnSeal in mesentery, muscle and liver. LigaSure and EnSeal operated at the lowest temperature in spleen without a significant difference between them. Thunderbeat produced significantly higher temperature peaks in all cases. The lowest mean MTZtotal was caused by LigaSure and EnSeal in spleen, mesentery and muscle without significant differences between them, followed by the significantly higher values of Thunderbeat. Nevertheless, Thunderbeat produced the significantly lowest mean MTZtotal in the liver. EnSeal produced the lowest mean MTZcollat in the liver, followed by LigaSure and Thunderbeat showing significant differences. EnSeal and LigaSure produced the lowest mean MTZcollat in the spleen, mesentery and muscle without significant differences between them, followed by the significantly higher values of Thunderbeat. Based on the results of this study, Thunderbeat seems to be more invasive to tissue integrity (even without the activation of the ultrasonic scissor function) than EnSeal or LigaSure, that operate at lower temperatures and were found to cause negligible collateral thermal damage.

In plant tissue culture, iron nanoparticles (FeNPs) was one of the first types of nano to be used in plants. Previous reports have identified the effect of FeNPs on many different plant species. In this study, FeNPs was used to replace Fe-EDTA in MS (Murashige, Skoog, 1962) medium to assess their effects on growth, chlorophyll (a, b and a+b) accumulation, antioxidant activity of ascorbate peroxidase (APX) and superoxide dismutase (SOD) enzymes, and acclimatization in greenhouse conditions in different culture systems (in vitro solid, in vitro hydroponic and microponic culture). The obtained results show that FeNPs added to MS medium was higher growth, chlorophyll (a, b and a+b) content, antioxidant activity of SOD and APX enzymes than Fe-EDTA in MS medium as control treatment. The effect of FeNPs are differences between culture systems. In vitro solid and microponic culture systems, the optimal concentration is 75 mM FeNPs and in vitro hydroponic culture system is 100 mM FeNPs. The optimal activity of the antioxidant enzyme SOD (35.04 U.mg−1 prot) obtained in the roots of cultured plants in microponic culture system; meanwhile, the optimal activity of the antioxidant enzyme APX (2.11 μmol.min−1.mg−1 prot) obtained in leaves cultivated in solid culture system. The plantlets derived from MS medium added FeNPs were transfered into greenhouse conditions, the microponic cultivated plants supplemented with FeNPs at a concentration of 100 mM gave the highest survival rate (94.67%). The results of this study showed that FeNPs can replace Fe-EDTA salt in MS medium, and iron deficiency in culture media will reduce chlorophyll content.

ABSTRACT Introduction: the onset of minimally invasive surgery, such as laparoscopic surgery, was accompanied by an increased frequency of complications, many of which were life-threatening. With the objective of minimizing morbidity and mortality and accelerating the learning curve, video laparoscopic surgery simulators were developed to improve the psychomotor skills required for these procedures. Objective: to compare the performance of second year medical students of the Lutheran University of Brazil, in simulated videolaparoscopic surgeries performed at the Realistic Simulation Center of the Faculty of Health Sciences of Porto Alegre. Method: prospective cohort study with 16 medical students with no prior experience in video-surgery simulation. The students performed simulated exercises and were evaluated regarding Coordination, Navigation by Instrument and Time in the accomplishment of the procedures. Results: the sample consisted of 69% women and 31% men with a mean age of 23.2 years. The students obtained better results in the second simulation application. The skill in Navigation by Instrument task was the one that showed the best evolution in the studied group. The Total Time in the accomplishment of the procedures was the parameter with greater difference between the successive simulations. Conclusion: medical students presented a significant improvement in their performance with the repetition of the simulation exercises, demonstrating that the Laparoscopic Surgery Simulators are a promising tool in medical training and development of surgical skills.
Medicalização do parto: os sentidos atribuídos pela literatura de assistência ao parto no Brasil
Authors: Nicida Lucia Regina de Azevedo , Teixeira Luiz Antônio da Silva , Rodrigues Andreza Pereira , Bonan Claudia
Published: November 2020

Resumo Este estudo analisa os sentidos atribuídos ao conceito de medicalização do parto a partir de uma revisão narrativa de literatura em periódicos nacionais publicados entre 2000 e 2017. Parte-se da concepção mais geral sobre medicalização – entendida como o processo pelo qual a medicina amplia e consolida a sua área de atuação nos diversos campos da sociedade – e das diferentes formulações do conceito concebidas por estudiosos do século XX. Foram construídas cinco categorias que relacionaram medicalização do parto com: intervenções, disputa profissional, violação de direitos das gestantes, cenário do parto e reflexo da medicalização da sociedade. Nas quatro primeiras categorias encontramos um predomínio de sentidos que exploram uma interface entre medicalização e humanização, constituindo-se como duas supercategorias analíticas, com um predomínio de uma crítica ao modelo medicalizado. Fugindo a este modelo de análise, a categoria medicalização do parto como reflexo da medicalização da sociedade se concentra em torno de um sentido de medicalização do parto como parte de um processo mais amplo que envolve diferentes atores que seriam copartícipes no processo de assistência, apontando para uma possibilidade de análise mais aprofundada em que considera a complexa conexão entre saúde e sociedade moderna.
