Constructo figural del dictador y efectos de una lectura en El Seductor de la Patria
Authors: De la Vara Estrada Ana Bertha
Published: December 2019

Antonio López de Santa Anna, el protagonista de El seductor de la patria, es precedido abrumadoramente por su homónimo histórico. La lectura de la novela implica, pues, una obligada confrontación entre el estereotipo cultural y el personaje novelesco construido por Enrique Serna. Por otra parte, la novela guarda fuertes vínculos temáticos y formales con la llamada novela de la dictadura hispanoamericana, lo cual confiere al personaje central ciertas determinaciones. En este trabajo se analiza la configuración del protagonista, teniendo en cuenta los recursos narrativos empleados en la representación de la conciencia figural, los elementos textuales y contextuales que participan en la articulación discursiva de la novela y los efectos de lectura derivados de la composición en su conjunto.
Huesos en el desierto: los asesinatos de mujeres de Ciudad Juárez y su productividad literaria
Authors: Kunz Marco , Kunz Marco
Published: December 2019

¿Quién mata mujeres en Ciudad Juárez? Nadie lo sabe o nadie lo dice y la única certeza que queda es la larga lista de las víctimas. El asunto, empero, ha influido fuertemente en la producción artística de los últimos tiempos. En las novelas (y películas) que estudia este trabajo se observa una mezcla de sentimientos de impotencia ante los crímenes y el deseo de encontrar una solución clara, sencilla y conforme con una cosmovisión propia, que haga salir a la luz a un grupo identificable de culpables y así poner fin a la serie de asesinatos. Con el análisis, se trata de probar que Ciudad Juárez no es el caso excepcional que excita tanto la fantasía de escritores, cineastas y cazadores de conspiraciones, sino la punta más visible de un iceberg cuya causa principal reside en la brutalización de la sociedad como consecuencia de la paulatina pauperización.

A política de silêncio do problema agrário brasileiro
Authors: Lerrer Débora , De Almeida Forigo Adriano
Published: December 2019

The article “The policy of silence of the Brazilian agrarian problem” undertakes a reflection on the marginalization of the agrarian reform theme over recent years, based on the pathways revealed by a truncated local recollection obtained through fieldwork carried out in 2015 and 2016, about a land conflict of the 1950s in Paraná. The hypothesis of the article is that the silencing of the Brazilian agrarian problem and the consequent marginalization and political fragility of peasant-oriented public policies are products of the “divided memory” associated with the way in which the expansion of capitalism in the countryside is produced and reproduced. The progress brought by the “businessmen” is exalted and, at the same time, ambivalence is expressed regarding the violence that has established these enterprises in these regions.Keywords: struggle for land; silencing; public policy.LERRER, Débora; FORIGO, Adriano de Almeida.

Neural model of relative mass flows of water and sugar in an installation for crystallizing and centrifuging A massecuite
Authors: Iciek Jan , Jezierski Arkadiusz
Published: December 2019

Three models of relative mass flows of water and sugar concerning crystallizing and centrifuging of A massecuite are presented. The input data for the calculation of particular flow volumes were the dry substance content wDS and sucrose content wS values measured in them during the sugarbeet campaign in one Polish beet sugar factory. These values, along with authors’ own knowledge and technological charts, provided the authors with the basis for the development of a mathematical model making possible the determination of appropriate, relative mass flows (sugar mass flow was accepted as the reference value) in a station for crystallizing and centrifuging of A massecuite. Then, an external balance model was developed to check the accuracy of the measured and of the calculated data. This model was provided with reliable data to develop a neural model. The developed and trained artificial neural network allowed for the simulation of relative water and sugar mass flows in an installation for crystallizing and centrifuging A massecuite. The results were satisfactory and the neural model developed was found to have a practical application in the simulation of the influence of particular sugar and water mass flows on the work of this installation.

Optimized standard of sugar manufacturing
from beet – first calculations
Authors: Lorenz Frieder
Published: December 2019

Within the framework of the work carried out by the VDZ Energy and Technical committee, in 2008 a review was undertaken of the status of energy consumption. This article serves as an introductory description of the continuation of this work. A model calculation is used to establish the factors influencing energy consumption. To start with, the model was set up and the influences of water evaporation on the energy consumption were investigated. In a further step, the effect of the temperature difference of the evaporator station and the pressure stage of the combined heat and power (CHP) station were established. An addition of water was to be avoided at all points, particularly in the sugar house. The influence of live steam pressure and the CHP–sugar factory interface will be disregarded when in future the consumption of heat energy (steam heat) is considered. The efficient supply of heat and electricity will in future be considered independent of it.

Published: December 2019

Purpose: Specialisation in hepatopancreatobiliary (HPB) surgery has evolved over the past few decades based on better understanding of the biology and the behaviour of the diseases. In this review from a specialised HPB service, we aim to provide an overview of the HPB oncological cases managed in a tertiary care cancer hospital. Methods: All cases of HPB malignancies treated in our hospital between October 2014 and September 2015 were included in the study. Clinical findings, operative details and short-term post-operative outcomes were assessed from a prospectively managed database. Results: A total of 65 oncological procedures were performed over 1 year. These included 23 hepatic resections, 27 pancreaticoduodenectomies, 5 radical surgeries for gallbladder cancer, 2 distal pancreatectomy and 8 nephrectomies with exploration of the inferior vena cava. One patient successfully underwent Associated Liver Partition with Portal vein ligation and staged hepatectomy (ALPPS Procedure), which to our knowledge was the rst ALPPS procedure carried out in Pakistan. Conclusion: The short-term experience of patients managed in specialised HPB unit has shown good outcomes.There is a need for establishing HPB units in most tertiary care hospitals in the country.

ARTERY FIRST TECHNIQUE FOR MANAGEMENT OF ABERRANT HEPATIC ARTERIAL ANATOMY DURING PANCREATICODUODENECTOMY-EXPERIENCE FROM A SPECIALIZED HEPATO-PANCREATO-BILIARY UNIT
Authors: Pirzada Muhammad Taqi , Sayyed Raza , Syed Aamir Ali , Hanif Fasial
Published: December 2019

Purpose: Aberrant hepatic arterial anatomy poses a challenge for surgeon during pancreaticoduodenectomy (PD). These anomalies are best picked up on pre-operative imaging to avoid inadvertent injury to the aberrant vasculature resulting in liver ischaemia or biliary-enteric anastomotic failure. We present our experience of dealing with aberrant hepatic vessels during PD. Methods: Patients with aberrant hepatic vasculature who underwent PD between September 2014 and August 2015 were included in the study. We used artery rst technique for dissection in cases identified on pre operative imaging. Aberrations were classed according to Hiatt classi cation. Results: A total of 23 PD were performed with aberrant arterial anatomy in 10 (43%) cases. These vessels were recognised and preserved in nine cases. In one patient, the replaced right hepatic artery (RRHA) arising from superior mesenteric artery (SMA) was coursing through pancreatic parenchyma needing resection and reconstruction with uneventful post-operative recovery. We also identified one RRHA arising from SMA coursing lateral to common bile duct and entering liver parenchyma in gallbladder fossa. Conclusion: Aberrant hepatic arterial anomalies are common and should ideally be picked up by pre-operative imaging. It is possible to preserve these vessels in most cases with careful surgical dissection using artery first technique. Surgeons performing PD should be well versed with the aberrant vascular anatomy to minimise any inadvertent damage. Key words: Aberrant hepatic artery, artery first technique, pancreaticoduodenectomy

A PICTORIAL REVIEW OF ONCOPLASTIC & RECONSTRUCTIVE BREAST SURGERY
Authors: Parvaiz Muhammad Asad , Roche Nicola , Rusby Jennifer , Goh Steven , Sircar Tapan
Published: December 2019

Oncoplastic surgery (OPS) of the breast has revolutionised the surgical practice in the past few years worldwide and has become an integral part of the breast cancer surgical treatment. OPS blends the principals of good local oncological control with plastic surgery techniques for immediate breast reshaping to provide best cosmetic results as well as oncological safety. It helps in extending the boundaries of breast-conservation treatment to include a group of patients who would otherwise require mastectomy to achieve complete excision of the tumour. OPS is a broad concept that can be used for several different combinations of oncological breast-conserving surgery and reconstructive surgery in the form of breast re-shaping/re-modelling. Careful patient selection and pre-operative planning are key components for the success of any OPS operation for breast cancer. Thorough surgical planning is mandatory including clinical assessment and breast measurements with reference to tumour/breast volume ratios. Mastectomy and total breast reconstruction are an option for patients that cannot have breast conservation. In this article, we provide a pictorial review of various oncoplastic and reconstructive breast operations, explaining the indications, essential principles, concepts and techniques of various surgical procedures.Key words: Breast cancer, oncoplastic surgery, breast reconstruction

Background: A high number of clinical T1 (cT1) stage renal cell carcinoma (RCC) is upstaged to pathological T3a (pT3a) stage on histopathological findings. Several study results show that there is no survival difference among those cT1 stage who are upstaged on histopathological findings to those who remain pT1 stage RCC.Objectives: The objectives of this study were to assess any survival difference for cT1 stage renal cell carcinoma (RCC) which is upstaged to pT3a stage as compared to those which remain pT1 stage RCC on histopathological findings.Materials and Methods: It was a retrospective cohort study looking at patient aged ≥18 years with cT1 RCC who underwent nephrectomy between January 2006 and December 2016. Patients were divided into two groups based on histopathological findings (pT1 vs. pT3a). Survival was analysed for the  two groups using Kaplan–Meier method, and the difference in survival was calculated using log-rank model.Results: The study included 187 patients. The mean age at presentation was 52.56 years, with 58.3% of the patients being male while 41.7% were female. The most common presentation was incidental diagnosis (50.3%). Overall5-year survival for cT1a and pT1a RCC was 68% while that for cT1a and pT3a RCC was 100%. There was no significant survival difference among the two groups (P = 0.316). The overall 5-year survival for cT1b and pT1b RCC was 81% while that for cT1b and pT3a was 65%. There was no significant survival difference among the two groups (P = 0.136).Conclusion: We found no survival difference in cT1 RCC who were upstaged to pT3a on histopathology as compared to cT1 RCC-staged pT1 on histopathology.Key words: Clinical T1 stage, pathological T3a stage, radical nephrectomy, renal cell carcinoma, survival
WHAT IS YOUR UNDERSTANDING OF SPINAL AND EPIDURAL ATTEMPT?
Authors: Yahya Salman , Siddiqui Athar Mukhtar
Published: December 2019

Background: The practice of spinal and epidural anaesthesia is well established the world over for a number of years. Sighting of spinal or epidural is conducted through various approaches at various levels of the spinal column. The number of attempts has its correlation with the post-spinal and epidural complications.Aim: The aim is to gather information about the understanding among the anaesthetists about the spinal/epidural attempt.Materials and Methods: A pro forma comprising of nine closed-loop questions was distributed to all the participants in the study, and they were requested to fill it anonymously and placed it back in a designated sealed box in anaesthetic  office.Results: A total of 20 pro formas were distributed, and all of them received back with 100% responses. All the participants accepted universally that attempting through another space makes it a second attempt. One of the respondents thought any backward movement means 2nd attempt, the majority of the responders thought it does not count as an attempt. Almost everyone considered another attempt if a needle is completely withdrawn and enters through another puncture site whether through a midline or paramedian approach.Conclusion: Most of the complications after neuraxial blockade are associated with the number of attempts alongside other factors that may play a role. A universal definition of a spinal and epidural attempt may decrease the complications associated with the central neuraxial blockade.Key words: Epidural, single attempt, spinal

The acylation of the acetonitrile anion with lactones and esters in ethereal solvents was successfully exploited using inexpensive KOt-Bu to obtain a variety of β-ketonitriles and trifunctionalized building blocks, including useful O-unprotected diols. It was discovered that lactones react to produce the corresponding derivatized cyclic hemiketals. Furthermore, the addition of a catalytic amount of isopropanol, or 18-crown-6, was necessary to facilitate the reaction and to reduce side-product formation under ambient conditions.

Arabinomannan (AM) polysaccharides are clinical biomarkers for Mycobacterium tuberculosis (MTB) infections due to their roles in the interaction with host cells and interference with macrophage activation. Collections of defined AM oligosaccharides can help to improve the understanding of these polysaccharides and the development of novel therapeutical and diagnostic agents. Automated glycan assembly (AGA) was employed to prepare the core structure of AM from MTB, containing α-(1,6)-Man, α-(1,5)-Ara, and α-(1,2)-Man linkages. The introduction of a capping step after each glycosylation and further optimized reaction conditions allowed for the synthesis of a series of oligosaccharides, ranging from hexa- to branched dodecasaccharides.

We present X-ray and radio monitoring observations of the gamma-ray binary PSR J2032+4127/MT91 213 during its periastron passage in late 2017. Dedicated Chandra, XMM-Newton, NuSTAR X-ray observations, and Very Large Array radio observations of this long orbit (50 yr), 143 ms pulsar/Be star system clearly revealed flux and spectral variability during the passage. The X-ray spectrum hardened near periastron, with a significant decrease in the power-law (PL) photon index from Γ ≈ 2 to 1.2 and evidence of an increased absorption column density. We identified a possible spectral break at a few keV in the spectrum that suggests synchrotron cooling. A coincident radio and X-ray flare occurred one week after periastron, which is possibly the result of the pulsar wind interacting with the Be stellar disk and generating synchrotron radiation. However, a multiwavelength comparison indicates that the X-ray and radio spectra cannot be simply connected by a single PL component. Hence, the emission in these two energy bands must originate from different particle populations.

Transit spectroscopy of terrestrial planets around nearby M dwarfs will be a primary goal of space missions in coming decades. Three-dimensional climate modeling has shown that slow-synchronous rotating terrestrial planets may develop thick clouds at the substellar point, increasing the albedo. For M dwarfs with T
eff > 3000 K, such planets at the inner habitable zone (IHZ) have been shown to retain moist greenhouse conditions, with enhanced stratospheric water vapor (fH
2O > 10−3) and low Earth-like surface temperatures. However, M dwarfs also possess strong UV activity, which may effectively photolyze stratospheric H2O. Prior modeling efforts have not included the impact of high stellar UV activity on the H2O. Here, we employ a 1D photochemical model with varied stellar UV, to assess whether H2O destruction driven by high stellar UV would affect its detectability in transmission spectroscopy. Temperature and water vapor profiles are taken from published 3D climate model simulations for an IHZ Earth-sized planet around a 3300 K M dwarf with an N2–H2O atmosphere; they serve as self-consistent input profiles for the 1D model. We explore additional chemical complexity within the 1D model by introducing other species into the atmosphere. We find that as long as the atmosphere is well-mixed up to 1 mbar, UV activity appears to not impact detectability of H2O in the transmission spectrum. The strongest H2O features occur in the James Webb Space Telescope MIRI instrument wavelength range and are comparable to the estimated systematic noise floor of ∼50 ppm.
Shocked Narrow-angle Tail Radio Galaxies: Simulations and Emissions

Published: December 2019

We present a numerical study of the interactions between the elongated active galactic nuclei outflows representing an evolved, narrow-angle tail (NAT) radio galaxy and planar, transverse ICM shock fronts characteristic of those induced by galaxy cluster mergers (incident Mach numbers 2–4). The simulated NAT formation was reported previously in O’Neill et al. Our simulations utilize a three-dimensional, Eulerian magnetohydrodynamic code along with energy-dependent Eulerian transport of passive cosmic ray electrons. Our analysis of the shock/NAT interaction applies a Riemann problem-based theoretical model to interpret complex shock front behavior during passage through the highly heterogeneous structures of the simulated NAT tails. In addition to shock compression, shock-induced vortical motions are observed within the tails that contribute to coherent turbulent dynamo processes that continue to amplify the magnetic fields in the tails well after initial shock compression. We analyze synthetic radio observations spanning the NAT-shock interaction period, and examine the brightness, spectral and polarization properties of our shock-rejuvenated radio tails, as well as the extent to which the pre-shock states of the plasma and particle populations in our tails influence post-shock observations. Finally, we evaluate our findings in the possible context of a physical analogy to our simulated NAT providing the precursor to a cluster “radio relic” associated with an impacting ICM shock.

Galaxies form in the centers of dark matter halos, and grow by accreting gas from the halos. The gas supply to the galaxy is the bottleneck for star formation and ultimately sets its stellar mass and star formation rate. As gas falls from the cosmic web into the halos, the highly supersonic infalling gas (Mach ∼20 for Milky Way-type halos) eventually forms a shock. If cooling is inefficient, this shock quickly stabilizes as a quasi-static slowly expanding accretion shock at the outer edge of the halo. If, however, cooling is important, a recent theory suggests that filaments of gas from the cosmic web will freefall unshocked through the halos, and shock only at the outskirts of the central galaxies. These “cold streams” allow for a steady supply of gas into the galaxies and for more efficient star formation. The cold dense filament flowing into a hot less dense environment is potentially Kelvin–Helmholtz unstable. This instability may hinder the ability of the stream to deliver gas deeply enough into the halo. A design of a well-scaled laser experiment on Omega-EP meant for studying this phenomena is presented in the current work, with relevant theory informed by 2D hydrodynamic simulations of the experiment. We establish the hydrodynamic scaling analysis between the cosmological system and its experimental analog, presenting the experiment as an adiabatic upper limit to informing the role of mixing due to the Kelvin–Helmholtz instability.

A statistical analysis of 15,210 electron velocity distribution function (VDF) fits, observed within ±2 hr of 52 interplanetary (IP) shocks by the Wind spacecraft near 1 au, is presented. This is the second in a three-part series on electron VDFs near IP shocks. The electron velocity moment statistics for the dense, low-energy core, tenuous, hot halo, and field-aligned beam/strahl are a statistically significant list of values illustrated with both histograms and tabular lists for reference and baselines in future work. Given the large statistics in this investigation, the beam/strahl fit results in the upstream are now the most comprehensive attempt to parameterize the beam/strahl electron velocity moments in the ambient solar wind. The median density, temperature, beta, and temperature anisotropy values for the core(halo)[beam/strahl] components, with subscripts ec(eh)[eb], of all fit results, respectively, are

We present results from a search for a radio transient associated with the LIGO/Virgo source S190814bv, a likely neutron star–black hole (NSBH) merger, with the Australian Square Kilometre Array Pathfinder. We imaged a 30 deg2 field at ΔT = 2, 9, and 33 days post-merger at a frequency of 944 MHz, comparing them to reference images from the Rapid ASKAP Continuum Survey observed 110 days prior to the event. Each epoch of our observations covers 89% of the LIGO/Virgo localization region. We conducted an untargeted search for radio transients in this field, resulting in 21 candidates. For one of these, AT2019osy, we performed multiwavelength follow-up and ultimately ruled out the association with S190814bv. All other candidates are likely unrelated variables, but we cannot conclusively rule them out. We discuss our results in the context of model predictions for radio emission from NSBH mergers and place constrains on the circum-merger density and inclination angle of the merger. This survey is simultaneously the first large-scale radio follow-up of an NSBH merger, and the most sensitive widefield radio transients search to-date.

Squalius microlepiswas examined from recent and historical collections within the known range of the species with special emphasis on intraspecific variability and variations, and compared to its closest relative speciesS. tenellus(in total, 193 specimens; 33 absolute and 52 proportional measurements and ratios, and 12 counts including vertebrae).Squalius tenelluswas perfectly differentiated in all statistical analyses and can be diagnosed by 76–95 (vs. 64–80) scales in lateral series, 68–83 (vs. 58–77) lateral-line scales, (17)18–20 (vs. 13–16(17)) scales above lateral line, and (7)8–10 (vs. 4–7) scales below lateral line.Squalius microlepiswas morphologically heterogeneous, with two phenotypes readily distinguishable (phenotype 1 corresponding toS. microlepiss. str. as defined by its lectotype) by a combination of many characters; those contributing most to the discrimination were number of gill rakers, length of lower jaw (% interorbital width), and head length (% SL). Only phenotype 1 was found in the Ričina-Prološko Blato-Vrljika karst system; most of the specimens from the lower Matica and the Tihaljina-Trebižat karst system were identified as phenotype 2; the sample from karstic poljes near Vrgorac contained both phenotype 1 and 2, and individuals of intermediate morphology. As very limited molecular data exist on the two phenotypes ofS. microlepis, we refrain from any taxonomic conclusions until new molecular approaches (and new markers) are used. We also report on a dramatic reduction of the area of distribution and abundance ofS. microlepisin recent years.
