Breve introducción a la antropología cognitiva
Authors: Salcedo Gómez Mariana , Platas-Neri Diana A.
Published: April 2021

El presente artículo tiene como objetivo realizar un acercamiento al tratamiento de algunos de los temas enmarcados en la intersección entre la antropología social o cultural y el estudio de la cognición. Para introducir el tema, las autoras nos dan una explicación de los antecedentes del campo de conocimiento que es la antropología, además de la importancia de la cultura dentro de esta disciplina. En particular, se hace referencia a la antropología cognitiva, un campo que comenzó a desarrollarse en Estados Unidos a mediados del siglo xx y que cobró fuerza y siguió nuevos derroteros en los años ochenta y noventa en Francia. Se realiza, por lo tanto, un recorrido por algunos conceptos que delimitaron las diferentes líneas de investigación en este campo de estudio. Uno de los factores más importantes dentro de la antropología cognitiva es el lenguaje que refleja la cultura de nativos en una región.
Integración de biopolímeros en la Industria Textil
Authors: Flores Nieves Mariana Montserrat , Soto Zarazúa Genaro Martín
Published: April 2021

Los textiles juegan un papel muy importante dentro de la vida cotidiana. A causa de la alta demanda, la industria textil ha provocado una sobre explotación de recursos naturales, causando problemas ecológicos y en algunos casos irreversibles. Es por ello, que se han buscado alternativas para el desarrollo de fibras, a partir de materiales ya existentes en la naturaleza, que no representen un problema ecológico. Los biopolímeros al tener como ventaja el poder modificar su naturaleza, se posicionan dentro de las principales alternativas para solucionar esta problemática y ser escalados a nivel industrial. Las investigaciones se han inclinado en desarrollar textiles de biopolímeros, que cumplan con los criterios del mercado. Dentro de estas fibras, encontramos las que provienen de las proteínas, que al pasar por una transformación química se pueden hilar, mejor conocidas como proteínas regeneradas, como las fibras con base caseína (la fibra más abundante de la leche), las cuales, al ser materiales biodegradables, amigables con el ambiente y con estructuras que se puede modificar, se pueden considerar como una alternativa factible, que puede cumplir con los requerimientos de los usuarios, sin dejar de lado un consumo socialmente responsable. En este artículo, se presenta un panorama general sobre los biopolímeros, como alternativas para materiales textiles, sus ventajas, usos y sus aplicaciones en el sector textil.
Plantas y bacterias, un vínculo para la vida
Authors: Dantán González Edgar , Pérez Martínez Rebeca Pérez Martínez
Published: April 2021

Las plantas han desarrollado una infinidad de estrategias para colonizar una gran variedad de hábitat, incluso para contender a los efectos tóxicos generados por actividades antropogénicas. La actividad minera genera una gran cantidad de residuos de metales pesados, que representan un riesgo potencial en la salud de los organismos vivos, incluyendo las plantas. Las plantas han establecido una asociación con rizobacterias resistentes a metales pesados y promotoras del crecimiento vegetal que desempeñan un papel vital en la adaptación a condiciones de estrés. Se ha estudiado la relación simbiótica entre plantas leguminosas provenientes de jales mineros y bacterias fijadoras de nitrógeno resistentes a metales pesados. Esta interacción ha resultado una opción prometedora como estrategia de fitorremediación al reducir no solamente las concentraciones y los efectos tóxicos de los metales; sino también evita la erosión y genera una mejora paulatina en la fertilidad del suelo.

Repairing of damaged composite materials and self-healing composites
Authors: KEPİR Yusuf , GÜNÖZ Alper , KARA Memduh
Published: April 2021

Repairing any damage in composite materials is very important in terms of the mechanical strength of the structure in which they are used. Therefore, the damage needs to be detected and repaired quickly. The increasing use of composite materials in various industries makes it more important to repair damage in composites both quickly and cost effectively. Patch repair method is one of the most preferred methods for repairing damaged composites because it does not create a new tension on the structure it is applied, does not damage the damaged area and is light. In addition, thanks to the embedded microcapsules placed in its matrix, self-healing composites have been studied in recent years. In this study, both the repair of composite materials and self-healing composites are discussed.

NMR Spectroscopic Method for Studying Homogenous Liquid Phase Reaction Kinetics in Systems used in Reactive Gas Absorption and Application to Monoethanolamine-water-carbon Dioxide
Authors: Behrens Richard , Dyga Maximilian , Sieder Georg , von Harbou Erik , Hasse Hans
Published: April 2021

An NMR spectroscopic method for measuring homogenous liquid phase reaction kinetics in systems that are used in reactive gas absorption processes is presented. In the kinetic experiment, carbon dioxide loaded and unloaded aqueous amine solutions are mixed such that no gas phase is involved. This procedure enables studying liquid phase reaction kinetics without the influence of the kinetics of the physical absorption process. A rapid-mixing NMR flow cell is used for the measurements, which are carried out in stopped-flow mode. 1H NMR spectra are taken at short intervals to monitor the kinetic process. The cell is liquid thermostatted and pressure resistant, such that a wide range of conditions can be studied. The new method was used for studying reaction kinetics in the system monoethanolamine (MEA)–water (H2O)–carbon dioxide (CO2) at temperatures between 293 and 333 K. From the data, information on the kinetics of the reaction of MEA with bicarbonate (HCO3-) to form MEA carbamate was obtained. That reaction was investigated for the first time in the present work without using bicarbonate salts. An Arrhenius model was fitted to the new data. The formation of MEA carbamate from MEA and HCO3- is often neglected in models for describing the reactive absorption of CO2 with aqueous MEA solutions. A process simulation study carried out in the present work reveals that it should be taken into account in predictions of reactive absorption processes that are operated under elevated pressure with a high mole fraction of CO2 in the gaseous phase.
Differential expression of molybdenum cofactor synthesis 1 in cancers of the breast.
Authors: Mamoor Shahan
Published: April 2021

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding molybdenum cofactor synthesis 1, MOCS1, when comparing primary tumors of the breast to the tissue of origin, the normal breast. MOCS1 mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of MOCS1 in primary tumors of the breast was correlated with overall survival in patients with basal subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by molecular subtype. MOCS1 may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Artikel ini membahas mengenai membangun karakter bangsa melalui penguatan keterampilan berpikir historis dalam pembelajaran sejarah. Sejarah sebagai sebuah mata pelajaran yang diajarkan di sekolah memiliki posisi yang sangat strategis dalam pelaksanaan pendidikan karakter. Terlebih lagi melihat dari hakikat pembelajaran sejarah itu sendiri adalah mengajarkan masa lalu kepada siswa untuk menjalani masa kini dan melihat masa depan. Begitu visionernya hakikat pembelajaran sejarah yang mengandung nilai-nilai masa lampau yang sejatinya merupakan cerminan nilai dari leluhur bangsa pendahulu. Sehingga dalam memahami setiap nilai dan makna dari peristiwa sejarah tersebut diperlukan sebuah keterampilan spesialis, yaitu berpikir historis (historical thinking). Keterampilan berpikir historis terbentuk tidak lepas dari peran guru sejarah dalam pembelajaran di sekolah. Bahkan berpikir historis ini sudah menjadi bahasan yang panjang dalam pembelajaran sejarah dari masa ke masa. Perlunya peningkatan keterampilan berpikir historis ini bisa direalisasikan dengan pengembangan model-model pembelajaran sejarah yang dapat menunjang keterampilan tersebut. Setidaknya di dalam artikel ini bertujuan untuk mengulas tentang membentuk karakter bangsa melalui penguatan keterampilan berpikir historis yang dikembangkan melalui model-model pembelajaran yang dikemas dengan nuansa baru (dalam kurun waktu 5 tahun terakhir) di masa sekarang dalam pembelajaran sejarah di sekolah.
Revisiting the Acquisition of Onset Complexity: Affrication in Québec French
Authors: Guzzo Natália Brambatti
Published: April 2021

I investigate the acquisition of affrication in Québec French (QF), where affricates are in complementary distribution with coronal stops, being realized before high front vowels and glides. Previous research on other languages shows that affricates are acquired before branching onsets, which supports the idea that complexity at the level of the segment is acquired before complexity at the level of the syllable (Lleó & Prinz, 1997). In contrast, I hypothesize that affricates are acquired after branching onsets in QF, as learners are required to understand the constraints on their distribution. I examine longitudinal data from two QF-speaking children for whom the acquisition of branching onsets has been previously analyzed (Rose, 2000). Results show that affricates are indeed acquired after branching onsets, consistent with the hypothesis. Overapplication errors indicate that children make generalizations about the phonological constraints on affrication from an early age, which is expected for the acquisition of rules.

Indonesia,negara yang sudah merdeka selama 75 tahun ini juga banyak menyimpan peristiwa sejarah dalamsetiap perjalanan waktunya. Peristiwa-peristiwa sejarah Indonesia akan diurutkan mulai darijaman prasejarah hingga masa kerajaan dan kemudian masa meraih kemerdekaan. Urutan-urutanperistiwa tersebut banyak yang menjadi penguat identitas bangsa. Aktifitas manusia yang bersifatdinamis mampu menggeser makna dari peristiwa sejarah, bahkan bisa merubah makna dari suatukelompok. Salah satunya terjadi pada perubahan konotasi pada preman. Preman pada jamankolonial dianggap sebagai pembela buruh yang tertindas oleh tuan-tuan tanah Belanda. Kinipreman dianggap sebagai kelompok yang meresahkan masyarakat, bahkan tak jarang diberijulukan sebagai “Sampah masyarakat”
Physicochemical Properties of LiFSI Solutions II: LiFSI with Water, MTBE, and Anisole
Authors: Neuhaus Johannes , von Harbou Erik , Hasse Hans
Published: April 2021

This article is the second in a series in which the thermodynamic properties of solutions of lithium bis(fluorosulfonylimide (LiFSI) are investigated. The solvents that are considered here are methyl tert-butyl ether (MTBE) and water (H2O), which are good solvents for LiFSI, and anisole, which is an antisolvent for LiFSI. The solubility of LiFSI in MTBE, as well as in the binary solvent mixture MTBE-anisole, was measured at temperatures of between 283 and 303 K and concentrations of LiFSI of up to 0.47 mol mol(-1). Furthermore, the liquid-liquid equilibrium of the system LiFSI-MTBE-H2O was studied at 293 K and ambient pressure. Moreover, the density and shear viscosity of solutions of LiFSI in MTBE were studied at temperatures between 273 and 308 K and concentrations of LiFSI up to 0.4 mol mol(-1).
Thermal Buckling Analysis of Composite Plates using Isogeometric Analysis based on Bezier Extraction
Authors: devarajan balakrishnan
Published: April 2021

Data transmission back and forth between finite element analysis (FEA) and computer-aided design (CAD) is a matter of huge concern today [2] and Isogeometric analysis [1] has been successful in merging these two fields in the recent past. The presentation will address isogeometric finite element approach (IGA) in combination with the first-order deformation plate theory (FSDT) for thermal buckling analysis of laminated composite plates. The IGA utilizes non-uniform rational B-spline (NURBS) as basis functions, resulting in both exact geometric representation and high order approximations [3] [4]. It enables to achieve easily the smoothness with arbitrary continuous order. The analyses have been performed using Bezier extraction and conventional IGA. In conventional isogeometric analysis the basis functions are not confined to one single element, but span a global domain whereas the Bézier extraction operator decomposes a set of linear combinations of Bernstein polynomials. The presentation will give a theoretical overview of B-splines, as well as NURBS, and also the concept of Bézier decomposition of these spline functions. The focus will then be on how the use of Bézier extraction eased the implementation into an already existing finite element code. This theoretical background will then be used to explain an isogeometric finite element analysis program. With the advent of More Electric Aircrafts [5], solving thermal structural problems [6] are of utmost importance in the aerospace industry. A static thermal structural validation problem will be presented for both constant and linear thermal temperature variation along the thickness. The presentation will then explain the procedures implemented for stress recovery and computing the geometric stiffness matrix. Numerical results of circular and elliptical plates will be provided to validate the effectiveness of the proposed method as compared to traditional FEA. The final section of the presentation proposes to detail the influences of length to thickness ratio, aspect ratio, boundary conditions, stacking sequence and material property on the critical buckling temperature. A special section would cover the idea of third order deformation theory for thicker plates and the effect of degree of NURBS basis on the results.
Preliminary prospects of a Carnot-battery based on a supercritical CO2 Brayton cycle
Authors: Rindt Karin Astrid Senta , Hrdlička František , Novotný Václav
Published: April 2021

As a part of the change towards a higher usage of renewable energy sources, which naturally deliver the energy intermittently, the need for energy storage systems is increasing. For the compensation of the disturbance in power production due to inter-day to seasonal weather changes, a long-term energy storage is required. In the spectrum of storage systems, one out of a few geographically independent possibilities is the use of heat to store electricity, so-called Carnot-batteries. This paper presents a Pumped Thermal Energy Storage (PTES) system based on a recuperated and recompressed supercritical CO2 Brayton cycle. It is analysed if this configuration of a Brayton cycle, which is most advantageous for supercritical CO2 Brayton cycles, can be favourably integrated into a Carnot-battery and if a similar high efficiency can be achieved, despite the constraints caused by the integration. The modelled PTES operates at a pressure ratio of 3 with a low nominal pressure of 8 MPa, in a temperature range between 16 °C and 513 °C. The modelled system provides a round-trip efficiency of 38.9 % and was designed for a maximum of 3.5 MW electric power output. The research shows that an acceptable round-trip efficiency can be achieved with a recuperated and recompressed Brayton Cycle employing supercritical CO2 as the working fluid. However, a higher efficiency would be expected to justify the complexity of the configuration.
Fear of psychotic relapse: exploring dynamic relationships with common early warning signs of relapse using electronic once-a-day self-reports

Published: April 2021

Background: Fear of relapse is an independent risk factor for future relapse events indicating its importance in clinical management and early warning signs-based relapse prevention monitoring.Methods: 25 participants who were taking part in a clinical trial of relapse prevention in schizophrenia responded to daily ecological momentary assessment prompts assessing common early warning signs of relapse and self-reported positive experiences like feeling supported by others. We conducted multilevel vector auto-regression using common symptoms assessed in early warning signs monitoring relapse prevention while controlling for positive self-reported experiences like feeling supported by others to estimate three networks (to explore concurrent, temporal and mean levels across the whole time period).Results: Reporting fear of relapse was positively associated (within the same cross-sectional time window) with hearing voices, alongside anxiety, negative affect and sleep change. Fear of relapse appeared to predict anxiety and negative affect on the next consecutive day. Experiencing fear of relapse on one day meant being more likely to also experience fear of relapse again at the next consecutive time point. However, none of the common early warning signs predicted fear of relapse within the temporal window and all observed relationships were small. Discussion: Early warning signs themselves appear poor predictors of experiencing fear of relapse but because fear of relapse predicts later anxiety and negative affect (even to a small degree) it may be a valuable intervention target within the daily life of people diagnosed with schizophrenia.
Expanding the environmental scope: An environment-wide association study for mental well-being

Published: April 2021

Identifying modifiable factors associated with well-being is of increased interest for public policy guidance. Developments in record linkage make it possible to identify what contributes to well-being from a myriad of factors. To this end, we link two large-scale data resources; the Geoscience and Health Cohort Consortium, a collection of geo-data, and the Netherlands Twin Register, which holds population-based well-being data. We perform an Environment-Wide Association Study (EnWAS), where we examine 139 neighbourhood-level environmental exposures in relation to well-being.First, we performed a generalized estimation equation regression (N = 11,975) to test for the effects of environmental exposures on well-being. Second, to account for multicollinearity amongst exposures, we performed principal component regression. Finally, using a genetically informative design, we examined whether environmental exposure is driven by genetic predisposition for well-being.We identified 21 environmental factors that were associated with well-being in the domains: housing stock, income, core neighbourhood characteristics, livability, and socioeconomic status. Of these associations, socioeconomic status and safety are indicated as the most important factors to explain differences in well-being. No evidence of gene-environment correlation was found.These observed associations, especially neighbourhood safety, could be informative for policy makers and provide public policy guidance to improve well-being. Our results show that linking databases is a fruitful exercise to identify determinants of mental health that would remain unknown by a more unilateral approach.
Free ranking vs. rank-choosing: New insights on the conjunction fallacy
Authors: Polakow Torr , Teodorescu Andrei , Busemeyer Jerome R , gordon goren
Published: April 2021

It has been consistently shown that when asked to rank options, people often make fallacious judgements. Furthermore, such fallacies can be sensitive to presentation mode. In the first study, we explored a novel type of ranking presentation, namely, choosing between two rank orders of options. To enable a direct comparison of fallacy rates between free ranking and the new presentation mode, we calculated the frequencies of the two presented rank orders in a free ranking condition. Our analysis shows that people choose the non-fallacious rank order significantly more when asked to choose between two rank orders as compared to freely ranking the possible options. In a second study, we explored whether an agent presenting the rankings to choose from has an effect. To alleviate social biases we used videos of social robots as the presenting agents. We show that rank orders presented by social agents significantly reduce the fallacy rates, compared to rank orders presented without an agent. We discuss the results in view of social decision making theories, wherein a ranking presentation by a social agent is comparable to a consultation with another person regarding free ranking. Our results suggest that fallacious decision making can be mitigated by a social agent presenting rankings to choose from.
Improvisation: A novel tool to study musicality
Authors: Weiss Michael W. , Peretz Isabelle
Published: April 2021

Humans spontaneously invent songs from an early age. Here, we exploit this natural inclination to probe implicit musical knowledge in 33 untrained and poor singers (amusia). Each sang 28 long improvisations as a response to a verbal prompt or a continuation of a melodic stem. To assess the extent to which each improvisation reflects tonality, a core organizational principle of musicality, we developed a new algorithm that compares a sung excerpt to a probability density function representing the tonal hierarchy of Western music. The results show signatures of tonality in both nonmusicians and individuals with congenital amusia, who have notorious difficulty performing musical tasks that require explicit responses and memory. The findings are a proof of concept that improvisation can serve as a novel, even enjoyable method for systematically measuring hidden aspects of musicality across the spectrum of musical ability.
The Political Context and Infant Health in the United States
Authors: Torche Florencia , Rauf Tamkinat
Published: April 2021

Most social determinants of health are shaped by political decisions. However, beyond specific policies, there is limited empirical investigation into the consequences of the changing political context on population health in the United States. We examine a salient political factor—the party of the president and governor—as a determinant of infant health between 1971 and 2018 using a battery of fixed-effects models. We focus on infant health because it has far-reaching implications for future population health and inequality. Our analysis yields three findings: (1) Democratic presidents have a beneficial effect on infant health outcomes, with stronger effects for Black infants compared to White infants. (2) The president’s party effect materializes after two years of a Democratic transition and remains elevated until the end of the party’s tenure in office. (3) Specific measurable social policies appear to play a minor role in explaining the beneficial effect of Democratic administrations. Our findings suggest the party in power is an important determinant of infant health, particularly among vulnerable populations, and they invite a deeper examination of mechanisms.

Это и проблема политической культуры стран Большого Кавказа, и идеологических констант, особенностей структуры элитариума, новейшей политической истории и геополитических стратегий. Компаративистская элитология затрагивает также и биографические особенности основных исторических персон, уровень их образования, основной и вспомогательный род занятий и профессиональную компетентность.

Molecular and Ultrastructural Analysis of a Porocephalus sp. (Arthropoda:
Pentastomida) Removed from a Rattlesnake
Authors: Goddard Jerome , Baker Gerald , Jericke Petra , Birchman Lawrence , Woodward Ethan , Rosser Thomas
Published: April 2021

Ultrastructural and molecular data are provided from a single adult female pentastomid opportunistically collected from a road-killed rattlesnake in Russell, KS. Ultrastructural data consisted of light and SEM microscopy of the pentastomid and its eggs, while molecular data consisted of partial 18S and 28S ribosomal sequences and a partial cytochrome c oxidase subunit 1 sequence from the same specimen used for SEM. Ultrastructural and molecular data support generic identification of the pentastomid as Porocephalus sp. These molecular data were also used with previously published pentastomid sequence data for a concatenated phylogenetic analysis, which support the current, morphology-based taxonomic placement of the genus.

ABSTRAKIndonesia memiliki potensi produksi akuakultur yang besar. Pada sektor perikanan, budidaya ikan diupayakan untuk memanfaatkan sumber daya air terbatas. Faktor yang memengaruhi kualitas dan pertumbuhan ikan adalah oksigen terlarut (dissolved oxygen). Microbubble generator (MBG) menjadi solusi untuk menyelesaikan masalah oksigen terlarut (DO) dalam air. Pengabdian ini akan melakukan modifikasi MBG tipe orifice dengan pipa porous dan pipa distributor. Selanjutnya mengkaji tentang pengaruh pipa distributor dengan variasi parameter pengujian terhadap stabilitas harga DO yang seragam pada air di kolam ikan. Pelaksanaannya akan melibatkan proses perancangan alat yang menghasilkan drawing design. Maka akan diteruskan ke proses pembuatan alat, setelah itu diuji fungsinya. Tahap akhir proses pengujian dalam air di kolam tanpa ikan untuk memperoleh harga DO yang stabil dan seragam. Dengan tujuan masyarakat dapat mengetahui, mengoperasikan, merawat, membuat alat secara swadaya (mandiri). Estimasi masyarakat mengetahui dari hasil kegiatan ini berkisar 84%. Hal ini ditinjau dari saat di lapangan dan taha evaluasi/monitoring telah dilakukan. Selain itu masyarakat mendapatkan dampak perekonomian yang positif, khususnya untuk komunitas peternak ikan skala kecil dan menengah yang tidak memiliki fasilitas seadanya. Kata kunci: dissolved oxygen; microbubble generator; orifice type; drawing design. ABSTRACTIndonesia has a large potential aquaculture production. In the fisheries sector, fish farming is sought to utilize limited water resources. Factors that affect the quality and growth of fish are dissolved oxygen (dissolved oxygen). Microbubble Generator (MBG) is the solution to resolve dissolved oxygen problems (DO) in water. This service will modify the ORIFICE type MBG with Porous pipes and distributor pipes. Furthermore, examine the influence of distributor pipes with variations in testing parameters on the stability of the price of DO uniformly on water in the fish pond. The implementation will involve the design process that produces drawing design. Then it will be forwarded to the tool making process, after which it is tested. The final stage of the testing process in water in a pond without fish to get a stable and uniform do price. With the aim of the community can know, operate, care for, make tools in self-help. Community estimates knowing from the results of this activity ranging from 84%. It is reviewed from the moment in the field and the evaluation/monitoring has been done. In addition, the community gets a positive economic impact, especially for small and medium-sized fish farmers who do not have makeshift facilities. Keywords: dissolved oxygen; microbubble generator; orifice type; drawing design.
