Coreografía de una matanza: memoria y performance de la masacre de Accomarca en el carnaval ayacuchano en Lima, Perú
Authors: Aroni Renzo 
Published: April 2023

El 14 de agosto de 1985, durante el largo conflicto armado interno entre la guerrilla maoísta de Sendero Luminoso - SL y el Estado peruano, una patrulla del Ejército entró en el pueblo andino de Accomarca, ubicado en la región de Ayacucho, y asesinó a 69 personas indígenas, incluyendo niños y ancianos, supuestos simpatizantes del grupo insurgente. La mayoría de los sobrevivientes y familiares de las víctimas se desplazaron a Lima y se integraron en una organización de víctimas y en la Asociación Hijos del Distrito de Accomarca - AHIDA. Desde el año 2011, con motivo de la extradición desde los Estados Unidos del mayor Telmo Hurtado, principal responsable de la masacre, la AHIDA ha recreado la dolorosa experiencia de la matanza a través de una performance anual del carnaval ayacuchano, incorporando coreografías y canciones testimoniales para exigir la justicia para las víctimas de la masacre. Esta performance carnavalesca integra a los niños y jóvenes que no vivieron la masacre, pero imaginan, interpretan y crean su propia memoria mediante la comunicación con los sobrevivientes y la participación en la producción cultural del evento.En este artículo expongo cómo los sobrevivientes y familiares de las víctimas recuerdan la masacre y transmiten sus memorias a sus hijos a través de una actuación carnavalesca. Describo la producción deuna memoria intergeneracional a través de la transmisión intergeneracional, que se construye en el espacio doméstico (familia), el espacio comunal/institucional (AHIDA), y el espacio público (carnaval). Sin duda, la ocasión del carnaval es un espacio de gran alcance para la producción de otras formas de memoria, y para la demanda de la justicia a través de una coreografía participativa y performance musical.
Un lugar para los shawi en la historia de Maynas
Authors: González Saavedra María Luisa 
Published: April 2023

Este texto pretende recabar las noticias que, sobre los shawi, seregistran en las fuentes escritas de la provincia de Maynas. El objetivo es acercarse, desde una perspectiva antropológica, a una sociedad que ya en el siglo XVI fue retratada desde la óptica de la evangelización. Siguiendo la cronología de las notas escritas por algunos de los conquistadores y misioneros españoles que llegaron a sus tierras, dibujaremos la silueta de un grupo que ha llegado a nuestros días posicionándose a la sombra de sus grupos vecinos: por un lado, los shiwilu, indios modelo de la evangelización jesuita; por otro, los awajun, quienes lograron vivir en su ‘gentilidad’, esto es, fuera de los límites misionales. Esta aparente neutralidad es la que define hoy a la sociedad shawi, que se siente indígena y cristiana a la vez.
Concepciones de niñez e identidad en las experiencias escolares de niños mapuche del Neuquén
Authors: Szulc Andrea 
Published: April 2023

En las comunidades mapuche del neuquén, las escuelas primarias continúan desempeñando un papel crucial como «enclave» estatal. en tal ámbito, se interpela fuertemente a los niños desde la definición identitaria hegemónica —que articula las pertenencias provincial, nacional y católica, subordinando a ellas la identidad mapuche— y desde un modelo escolar de niñez. La investigación antropológica realizada allí desde el año 2001 viene evidenciando cómo algunos niños, niñas y adolescentes en numerosas ocasiones cuestionan abiertamente tales concepciones.Tras una breve descripción del sistema educativo regional,el presente artículo explora entonces las experiencias educativas de estos niños y niñas mapuche del neuquén, examinando las concepciones de niñez y de la identidad mapuche que sus prácticas de resistencia ponen en tensión. A partir principalmente de materiales etnográficos originales, el análisis revela cómo desde esta actitud contestataria no sólo se han afirmado como mapuche, sino también cómo han conseguido atravesar «exitosamente» por el sistema educativo.
Traceability of the Micro Scale Pipe Viscometer for Traceable Calibration of Dynamic Viscosity
Authors: Neuhaus Stefanie , Bissig Hugo , Bircher Benjamin A. , De Huu Marc 
Published: April 2023

Calibration of flow devices is important in several areas of pharmaceutical, flow chemistry and microfluidic applications where dosage of process liquids or accurate measurement of the flow rate is important. The process-oriented liquid itself might influence the performance of the flow device and the simultaneous determination of the dynamic viscosity under flow conditions might be a valuable information for the process parameters. To offer the simultaneous calibration of the dynamic viscosity of the process-oriented liquid at the corresponding flowrate, METAS has built a pipe viscometer for the traceable in-line measurement of the dynamic viscosity in the current flow facilities for low flow rates from 1 L/min to 150 mL/min and pressure drops up to 10 bar. The traceability of all the measuring quantities as well as the geometrical dimensions of the micro tube guarantee the traceability of the pipe viscometer to SI units. The most challenging part is the traceable determination of the inner diameter of the micro tube. This can be achieved by measuring the pressure drop as a function of flow rate with the pipe viscometer and applying the law of Hagen-Poiseuille with a traceable dynamic viscosity of a reference liquid (water) or perform the measurements with the micro-CT at METAS, which determines the inner diameter by x-ray diffraction. The validation of the stated measurement uncertainty of the pipe viscometer has been performed by means of calibration of the dynamic viscosity of several reference liquids with traceable density and kinematic viscosity. The setup of the facility, the traceability as well as the uncertainty calculation of the pipe viscometer for the in-line measurement of the dynamic viscosity are discussed in this paper.

Published: April 2023

Background:
Ream-and-run arthroplasty can improve pain and function in patients with glenohumeral arthritis while avoiding the complications and activity restrictions associated with a prosthetic glenoid component. However, stiffness is a known complication after ream-and-run arthroplasty and can lead to repeat procedures such as a manipulation under anesthesia (MUA) or open surgical revision. The objective of this study was to determine risk factors associated with repeat procedures indicated for postoperative stiffness after ream-and-run arthroplasty.

Methods:
We conducted a retrospective review of our shoulder arthroplasty database to identify patients who underwent ream-and-run arthroplasty and determined which patients underwent subsequent repeat procedures (MUA and/or open revision) indicated for postoperative stiffness. The minimum follow-up was 2 years. We collected baseline demographic information and preoperative and 2-year patient-reported outcome scores and analyzed preoperative radiographs. Univariate and multivariate analyses determined the factors significantly associated with repeat procedures to treat postoperative stiffness.

Results:
There were 340 patients who underwent ream-and-run arthroplasty. The mean Simple Shoulder Test (SST) scores for all patients improved from 5.0 ± 2.4 preoperatively to 10.2 ± 2.6 postoperatively (p < 0.001). Twenty-six patients (7.6%) underwent open revision for stiffness. An additional 35 patients (10.3%) underwent MUA. Univariate analysis found younger age (p = 0.001), female sex (p = 0.034), lower American Society of Anesthesiologists (ASA) class (p = 0.045), posterior decentering on preoperative radiographs (p = 0.010), and less passive forward elevation at the time of discharge after ream-and-run arthroplasty (p < 0.001) to be significant risk factors for repeat procedures. Multivariate analysis found younger age (p = 0.040), ASA class 1 compared with class 3 (p = 0.020), and less passive forward elevation at discharge (p < 0.001) to be independent risk factors for repeat procedures. Of the patients who underwent open revision for stiffness, 69.2% had multiple positive cultures for Cutibacterium.

Conclusions:
Younger age, ASA class 1 compared with class 3, and less passive forward elevation in the immediate postoperative period were independent risk factors for repeat procedures to treat postoperative stiffness after ream-and-run arthroplasty.

Pressure Transient Analysis for Water Injection Wells with Waterflooding-Induced Nonsimultaneously Closed Multistorage Fractures: Semianalytical Model and Case Study

Published: April 2023

Summary
Waterflooding will induce the opening and extension of fractures, which will create some water flow channels. Due to fracture multiclosures, the obtained fracture half-length from conventional finite-conductivity models is less than the actual value, leading to water flow channels that have been formed but not detected by engineers. According to a large number of waterflooding-front matching schematics and interwell connection coefficient analyses, we find that waterflooding usually connects natural fractures to form bi-induced fractures, which will close nonsimultaneously during the falloff test. In this paper, we develop a waterflooding-induced nonsimultaneously closed multistorage fracture model (WNMF) to describe waterflooding-induced fracture characteristics accurately. The bi-induced fractures are separated into multiple segments to calculate their pressure response. The closed induced-fracture conductivities are constant, and the opened induced-fracture conductivities follow the exponential equation measured by the experiments. Induced-fracture interference and multistorage effects are considered. Finally, the Duhamel principle is used to characterize the storage effects of bi-induced fractures and the wellbore. Results show that the type curve of the WNMF model has bi-peaks on the pressure derivative curve, which was regarded as error data in the past. Closed induced-fracture half-length is identified quantitatively. We can obtain an induced-fracture angle by matching the interference flow (an innovative flow regime in this paper), which can guide engineers to prevent and monitor water breakthrough in time. Using the obtained parameters (induced-fracture angle and closed induced-fracture half-length) can guide well pattern encryption and reasonable well location determination. If the induced-fracture angle is 90°, an additional horizontal line will be shown on the pressure derivative curve. When the horizontal line is misidentified as a quasiradial flow regime, the obtained reservoir permeability will be amplified many times. The multistorage coefficient is obtained to correct the magnified storage coefficient. Equation calculation and model matching methods verify each other to improve closed induced-fracture half-length accuracy. In conclusion, the experiment and mathematical model methods work together to describe the pressure response behavior of water injection wells. The WNMF model is compared with the conventional finite-conductivity model to verify its accuracy. A field case demonstrates its practicality.

Abstract
Dynamic morphological changes in the chromosomes and cytoskeleton occur in mammals including humans, during early embryonic development, and abnormalities such as embryonic chromosomal aneuploidy occur when development does not proceed normally. In previous reports, the behavior of DNA and cytoskeleton in early mammalian embryos has conventionally been visualized and observed by injecting target molecule mRNA, with a fluorescent substance-expressing gene incorporated, into embryos. However, injecting genetic information into a human embryo to induce the production of unnatural proteins must be carefully considered from an ethical perspective. Therefore, we aimed to develop a simple observation method as a way of gaining knowledge about the first division that can avoid such problems. We visualized the chronological behavior of male and female chromosome condensation in mammalian embryos, beginning in the 2PN zygote, through the first division into the two-cell stage by using fluorescent chemical probes for DNA, microtubules, and microfilaments. This method is simple and does not require genetic manipulation, and its application can be observed at any stage during embryonic development, thereby providing novel insights into embryonic development in many mammals. In particular, it is expected to provide a great deal of cell biological information on the first cleavage of human embryos, which have been reported to exhibit a variety of patterns.
A Matlab code of topology optimization by imposing the implicit floating projection constraint
Authors: Huang Xiaodong 
Published: April 2023

Abstract
This paper presents a Matlab code to implement the three-field floating projection topology optimization (FPTO) method using the linear material interpolation scheme. The implicit floating projection constraint in the FPTO method numerically simulates 0/1 constraints of the design variables so that even a linear material interpolation scheme can be employed. By gradually tightening 0/1 constraints, more and more design variables are pushed to 0/1 until an optimized element-based design with a clear topology can be accurately represented by a smooth design. In general, the implicit floating projection constraint provides a numerical engine for topology optimization, which is fundamentally different from the existing topology optimization methods. The Matlab code in this paper describes the numerical implementation of such an implicit constraint and the extraction and evaluation of the smooth design in detail. Apart from the compliance minimization problem, the Matlab code can be equally applied to other extended topology optimization problems. The provided Matlab code enables the users to understand and test this newly-developed topology optimization method for their own topology optimization problems.
Evaluation of water-energy-food-environment-agricultural economic growth nexus integrated approach to achieve sustainable production

Published: April 2023

Abstract
Today, growing the production of the agricultural sector in order to meet the increasing demand of food is happening through excessive consumption of water resources, energy, chemical fertilizers and pesticides, especially in developing countries. Therefore, the present study aims to design a new approach for sustainable management of resources and realization of clean production in the agricultural sector. In order to design the new approach of the present study, the integration of two concepts of water-energy-food (WEF) nexus and decoupling pollution- agricultural growth (DEC) was used. The proposed approach is modeled through the multi-objective programming model by optimizing the WEF and DEC indices, which is the first research effort in this field. In this regard, the performance of this approach was evaluated in Jiroft county in Kerman province, Iran. The results of the study showed that the consumption of chemical fertilizers and pesticides in the optimal pattern with the simultaneous provision of WEF and gross margin (GM) goals (Optimal 1) is about 110 kg and 0.19 liters per hectare, respectively, more than the proposed pattern (Optimal 3). On the other hand, the consumption of water and energy resources in the optimal pattern with the simultaneous provision of DEC and GM goals (Optimal 2) is about 8785 cubic meters and 1108 MJ per hectare more than the proposed pattern (Optimal 3), respectively. Therefore, this approach, due to the simultaneous integration of two concepts of sustainable development in the agricultural sector, can overcome the weakness of the WEF nexus in not paying attention to the issues of environmental pollution affected by the use of chemical inputs and the weakness of separating pollution- agricultural growth in not paying attention to the management of water and energy resources in the agricultural sector.

Published: April 2023

Abstract
Liquid-liquid phase separation is the process in which two immiscible liquids demix. This spontaneous phenomenon yields spherical droplets that eventually coarsen to one large, stable droplet governed by the principle of minimal free energy. In chemically fueled phase separation, the formation of phase-separating molecules is coupled to a fuel-driven, non-equilibrium reaction cycle.1 It thus yields dissipative structures sustained by a continuous fuel conversion.2 Such dissipative structures are ubiquitous in biology3 but are poorly understood as they are governed by non-equilibrium thermodynamics.4 Here, we bridge the gap between passive, close-to-equilibrium, and active, dissipative structures with chemically fueled phase separation. We observe that spherical, active droplets can transition into a new morphology—a liquid, spherical shell of droplet material. A spherical shell is highly unstable at equilibrium, and this dissipative structure can be sustained only by continuous conversion of chemical energy. We demonstrate that the mechanism is related to gradients of shortlived droplet material. We characterize how far out of equilibrium the spherical shell state is and the chemical power necessary to sustain it. Our work suggests new avenues for assembling complex stable morphologies, which might already be exploited to form membraneless organelles by cells.
Antimicrobial Properties of Free and Encapsulated-essential Oil into Chitosan of Rosemary

Published: April 2023

Abstract
Pathogenic microbes are the most common cause of chronic infections and mortality in mammals and loss of agricultural crops in the world. Antimicrobial agents including antibiotics and antifungals are often used in the treatment of infections due to their exceptional consequences faces various problems that limits the treatment by them. Therefore, herbal sources are attracting more attention due to lower side effects and in some cases better and faster effects. Plant essential oils (EOs) have many antimicrobial and pharmacological effects, but EOs are volatile, heat-sensitive and water-insoluble compounds that limit their use, encapsulating EOs can improve the properties of such compounds. Chitosan, a biodegradable nanopolymer, is very important in drug transfer due to better encapsulation, controlled release and low toxicity. Therefore, this research was conducted to investigate the encapsulation technique as a suitable method to preserve essential oils and increase their antimicrobial properties. First, the chitosan polymer was synthesized and used to encapsulate rosemary essential oil after examining its shape and size by spectroscopy (FTIR) and scanning electron microscopy (SEM). Then, the antibacterial effect of encapsulated EO and free EO was investigated by liquid microdilution method. The results showed that encapsulated EO had a greater antibacterial effect against gram-negative bacteria and fungi compared to free EO.
Revisiting the anatomy of myrtiformis muscle

Published: April 2023

Abstract
Background and Purpose The nasal base muscles are of great functional importance in health and disease. Particularly, the one lacking terminological consensus, but often termed as myrtiformis muscle, which has been mostly omitted by anatomists may have significance for rhinoplasty. The purpose of the current study was to re-examine the anatomical features of myrtiformis muscle.Materials and Method Conducted on 40 sides of 20 formalin-fixed amputated heads, we followed a dissection routine to fully expose the origin and insertion sites of the nasal base muscles. We measured the respective morphometric via digital caliper.Results Based on the number of bellies and their muscular attachment sites, we described an anatomical classification that consists of three different types of MM which had a single and broad origin. We classified the double bellied muscle as Type 1 occurred in 10% (4/40), whereas the single bellied ones as Type 2 and 3, classified in 80% (32/40) and 10% (4/40), respectively. Measured distance between the medial margin of myrtiformis muscle origin and midline passing through the anterior nasal spine did not differ between any statistical comparisons (P > 0.05).Conclusion We revisited the muscle which was at some occasions termed as myrtiformis muscle, depressor septi nasi or depressor alae nasi muscles. Considering that there are differential forms of the muscle with the same muscular origin but bearing single or double bellies and/or different insertion sites, our classification may overcome possible terminological confusion by ensuring single muscle term with easily distinguishable morphological types. We invite anatomists to enlarge the data set and comment on our classification, and surgeons to conduct prospective examinations to add deeper insight regarding the functional importance of anatomical classifications by correlating pre vs post-operative functional differences.
v3c-viz: Visualization and data exploration of chromosome conformation capture data at full resolution using Voronoi diagrams
Authors: Race Alan , Fuchs Alisa , Chung Ho-Ryun 
Published: April 2023

Abstract
Chromosome conformation capture (3C) sequencing approaches, like Hi-C or micro-C, allow for an unbiased view of chromatin interactions. Most analysis methods rely on so-called interaction matrices, which are derived from counting read pairs in bins of fixed size. To achieve high spatial resolution the general perception is that a high sequencing depth is required. Here, we show that high spatial resolution does not require high sequencing depth using the Voronoi diagram, as implemented in Voronoi for chromosome conformation capture data visualization (v3c-viz). The Voronoi diagram corresponds to an adaptive-binning strategy that adapts to the local densities of points. In this way, visualization of data obtained by moderate sequencing depth pinpoint many, if not most, interesting features such as high frequency contacts. The superior visualization properties of the Voronoi diagram calls for further developments towards algorithms for identifying contacts at a resolution approaching the typical size of enhancers and promoters.v3c-viz is available at https://github.com/imbbLab/v3c-viz
