El Diario de Francisca: Representaciones infantiles sobre la violencia política en la vida cotidiana durante los 70 / Francisca’s private diary: Childhood representations of political violence in everyday life during the 70s
Authors: Jara Daniela 
Published: January 2020

En este artículo se propone una lectura del Diario de Francisca, un registro autobiográfico escrito en plenos días de la Unidad Popular y el golpe de Estado por una niña de 11 años, miembro de una familia urbana de clase media alta. Luego de situar brevemente al diario íntimo o de vida como una práctica cultural propia de la modernidad, se analiza la manera en que el texto ilumina las operaciones a través de las cuales la niña va habitando el mundo, entramadas en dinámicas socio-afectivas mediadas, interrumpidas o potenciadas por la clase. Se sugiere que las representaciones infantiles articuladas en la escritura del diario íntimo muestran diversos aspectos de la producción y transmisión de la memoria de la violencia política, y de la relación con los contextos de su producción. El Diario describe una escena de la violencia política en que ésta, lejos de producirse de manera intempestiva, ya estaba instalada en las formas de la vida cotidiana de la Unidad Popular (UP). Así, la voz de la niña nos permite ver cómo la violencia política está en parte instalada y cómo va instalándose en la sociedad civil durante la UP, ya no sólo entre víctimas y perpetradores, sino también entre los niños, quienes participan de ésta, la negocian y recrean o reproducen.

This article focuses on Francisca's Diary, an autobiographical record written during the Unidad Popular (UP) period, more specifically in 1973. Francisca, an 11 year old girl, member of an urban middle-class family, witnesses the military coup and produces an intimate account of the events. After briefly situating the personal diary as a cultural practice typical of modernity, I will reflect on the way in which the text illuminates the operations through which the girl inhabits the world, embedded in socio-affective dynamics, interrupted or enhanced by social class. I suggest that Francisca’s Diary sheds light on various aspects of the production and transmission of the memory of political violence, the role of children representations and their relationship with the contexts in which they are produced. Also, I suggest that the Diary portraits a scene in which political violence was already embodied in the everyday life during the UP, no longer as a monopoly of victim and perpetrator agents. Rather I draw attention to the way in which the child negotiates, reproduces, represents and resists violence.

В настоящее время резервы в повышении производительности современных процессоров практически исчерпаны, что проявляется в отсутствии роста, как тактовой частоты, так и числа команд, выполняемых в такт, которые определяют скалярную производительность процессорного ядра. В разрабатываемом векторном процессоре с архитектурой управления потоком данных (векторном потоковом процессоре) производительность процессорного ядра может быть повышена до 256 флоп в такт на ядро, что в 8 раз выше по сравнению с последними процессорами Intel Xeon. Это достигается за счет более высокой доли векторных вычислений. В работе показано, что отношение реальной производительности к пиковой на программах битонной сортировки, умножения матриц и 2D Stencil у векторного потокового процессора выше, чем у лучших процессоров традиционной архитектуры.

Authors: Singh Manisha , Tiwari Ishwar , Bhandari Dinesh , Katwal Basanta 
Published: January 2020

Aims: To identify existing interventions in South East Asian countries implemented to prevent postpartum depression (PPD) and explore the possibility of replication of such interventions in Nepal to reduce it.
Methods: The paper reviewed the risk factors and preventive strategies implemented in South East Asian countries to prevent PPD.
Results: Enough actions have not been taken to address PPD despite of high prevalence in the reviewed countries (Bangladesh, India, Pakistan, Srilanka and Nepal). However, some of the interventions used such as cognitive behavior therapy, education for girls, poverty alleviation program, participatory approach for empowerment and involvement of community health workers have shown positive impact on reducing PPD.
Conclusions: The interventions used in South East Asian countries were simple in design intervention and mostly conducted through community health workers; it showed a possibility of replication in Nepal as it already has sufficient community workforces working in maternal and child health.

Failure Analysis of a Jet Engine Gearbox Drive Gearshaft Ball Bearing
Authors: Villa Rodolfo , Roswurm Scot 
Published: January 2020

Abstract
The case study presented in this article details the failure investigation of an M50 alloy steel bearing used in a jet engine gearbox drive assembly. It discusses the investigative steps and analytic tools used to determine the root cause, highlighting the importance of continuous, thorough questioning by the investigating activity. The combined analyses demonstrated that the bearing failed by a single event overload as evidenced by bulk deformation and traces of foreign material on the rolling elements. The anomalous transferred metal found on the rolling elements subsequently led to the discovery of overlooked debris in an engine chip detector, and thus resulted in a review of several maintenance practices.
Failure Analysis of AISI-304 Stainless Steel Styrene Storage Tank
Authors: Asghar M.S. Ali , Tariq F. , Ali A. 
Published: January 2020

Abstract
A storage tank had been in service at a petrochemical plant for 13 years when inspectors discovered cracks adjacent to weld joints and in the base plate near the foundation. The tank was made from AISI 304 stainless steel and held styrene monomer, a derivative of benzene. The cracks were subsequently welded over with 308 stainless steel filler wire and the base plate was replaced with new material. Soon after, the tank began leaking along the weld bead, triggering a full-scale investigation; spectroscopy, optical and scanning electron microscopy, fractography, SEM-EDS analysis, and microhardness, tensile, and impact testing. The results revealed transgranular cracks in the HAZ and base plate, likely initiated by stresses developed during welding and the presence of chloride from seawater used in the plant. It was also found that the repair weld was improperly done, nor did it include a postweld heat treatment to remove weld sensitization and minimize residual stresses.
Metallurgical Investigation of Failed Locked Coil Track Ropes Used in a Mining Conveyor
Authors: Dhua S.K. , Singh C.D. , Ray Amitava 
Published: January 2020

Abstract
A locked coil track rope (LCTR) is essentially composed of wires (round and rail-shaped) laid helically in different layers. These wire ropes are sometimes used in conveyors carrying empty and loaded buckets in mining areas. During service, such wire ropes may fail prematurely due to disintegration/failure of individual groups of wires. To understand the genesis of LCTR wire failures, a detailed metallurgical investigation of failed rope wires was made and included visual examination, optical microscopy, scanning electron microscopy (SEM), and electron probe microanalysis (EPMA). Two types of failed wires were investigated; one is from a 40 mm diameter locked coil track rope and the other from a 53 mm locked coil track rope. Optical microscopy of failed round wires in the 53 mm diameter rope clearly revealed fully decarburized layers at the surface and a few grain-boundary cracks. From the location of the failure, it was clear that apart from static tensile loads, the wire ropes had been subjected to bending and unbending loads near the saddle, as fully loaded or empty buckets traveled access the conveyor. The SEM studies confirmed that the fracture had been caused by initiation of fatigue cracks in the decarburized zone under conditions of repeated bending and unbending stresses superimposed on the static tensile load.

Published: January 2020

Abstract
A pipe in the lateral wall of a boiler powering an aircraft carrier flat-top boat failed during a test at sea. The pipe was made from ASTM 192 steel, an adequate material for the application. Microstructural analysis along with equipment operating records provided valuable insight into what caused the pipe to rupture. Although the pipe had been replaced just 50 h before the accident, the analysis revealed incrustations and corrosion pits on the inner walls and oxidation on the outer walls. Microstructural changes were also observed, indicating that the steel was exposed to high temperatures. The combined effect of pitting, incrustations, and phase transformations caused the pipe to rupture.
Failure Analysis of NiTi Wires Used in Medical Applications

Published: January 2020

Abstract
Superelastic nitinol wires that fractured under various conditions were examined under a scanning electron microscope in order to characterize the fracture surfaces, produce reference data, and compare the findings with prior published work. The study revealed that nitinol fracture modes and morphologies are generally consistent with those of ductile metals, such as austenitic stainless steel, with one exception: Nitinol exhibits a unique damage mechanism under high bending strain, where damage occurs at the compression side of tight bends or kinks while the tensile side is unaffected. The damage begins as slip line formation due to plastic deformation, which progresses to cracking at high strain levels. The cracks appear to initiate from slip lines and extend in shear (mode II) manner.
Analysis and Subsequent Testing of Cracked Brass Connector Housings
Authors: Mueller Tim , Burns Neil 
Published: January 2020

Abstract
Coaxial cable connectors made of brass were failing at a high rate after less than one year of service in an outdoor industrial environonment. The observed failures, which consisted of cracks in the body and end cap, were analyzed and found to be brittle fractures due to stress-corrosion cracking. Two common stress-corrosion cracking tests for copper materials were conducted on new connectors from the same manufacturing lot, confirming the initial determination of the fracture mode. Additional testing as was done in the investigation is often helpful when analyzing corrosion failures.
Analysis of Critical Stress for Subsurface Rolling Contact Fatigue Damage Assessment Under Roll/Slide Contact
Authors: Qin Xiao-feng , Sun Da-le , Xie Li-yang 
Published: January 2020

Abstract
Rolling contact fatigue is responsible for a large number of industrial equipment failures. It is also one of the main failure modes of components subjected to rolling contact loading such as bearings, cams, and gears. To better understand such failures, an investigation was conducted to assess the role of friction in subsurface fatigue cracking in rolling-sliding contact applications. Based on the results of stress calculations and x-ray diffraction testing of steel samples, friction contributes to subsurface damage primary through its effect on the distribution of orthogonal shear stress. Although friction influences other stress components, the effect is relatively insignificant by comparison. It is thus more appropriate to select orthogonal shear stress as the critical stress when assessing subsurface rolling contact fatigue in rolling-sliding systems.
Failure Analysis of T12 Boiler Re-Heater Tubes During Short-Term Service
Authors: Hu Zheng-Fei , He Da-Hai , Wu Xi-Mao 
Published: January 2020

Abstract
The failure of T12 reheater tubes that had been in service for only 3000 h was investigated. The thickness of the tubes was visibly reduced by heavy oxidation corrosion on the inner and outer walls. The original pearlite substrate completely decomposed. Uniform oxide scale observed on the inner wall showed obvious vapor oxidation corrosion characteristics. Corrosion originated in the grain boundary, and selective oxidation occurred due to ion diffusion in the substrate. The layered oxide scale on the inner wall is related to the different diffusion rates for different cations. Exposure to high temperature corrosive flux accelerated the corrosion on the outer wall. Microstructure degradation and the corrosion characteristics observed indicate that the tubes failed primarily because of overheating, which is confirmed by calculations.
Failure Analysis of HAZ Cracking in Low C-CrMoV Steel Weldment
Authors: Naz Nausheen , Tariq Fawad , Baloch Rasheed Ahmed 
Published: January 2020

Abstract
This case study describes the failure analysis of a steel nozzle in which cracking was observed after a circumferential welding process. The nozzle assembly was made from low-carbon CrMoV alloy steel that was subsequently single-pass butt welded using gas tungsten arc welding. Although no cracks were found when the welds were visually inspected, X-ray radiography showed small discontinuous surface cracks adjacent to the weld bead in the heat affected zone. Further investigation, including optical microscopy, microhardness testing, and residual stress measurements, revealed that the cracks were caused primarily by the presence of coarse untempered martensite in the heat affected zone due to localized heating. The localized heating was caused by high welding heat input or low welding speed and resulted in high transformation stresses. These transformation stresses, working in combination with thermal stresses and constraint conditions, resulted in intergranular brittle fracture.

Published: January 2020

Abstract
A forging die in a 250-ton press producing brass valves began to show signs of fatigue after a few thousand hits. By the time it reached 30,000 hits, the die was badly damaged and was submitted for analysis along with one of the last forgings produced. The investigation included visual and macroscopic inspection, metallographic and chemical analysis, SEM imaging, optical profilometry, mechanical property testing, and EDX analysis. The die was made of chromium hot-work tool steel and the forgings were made of CuZn39Pb3 heated to an initial working temperature 700 deg C. The entire surface of the die was covered with fatigue cracks and many fillets had been plastically deformed. Several other types of damage were also observed, including areas of oxidation, corrosion pits, voids, abrasive wear, die adhesion, and thermal fatigue. Fatigue cracking was the primary cause of failure with significant contributions from the other damage mechanisms.

Relevance. Influenza is characterized by global distribution and the difference in its seasonality in countries with temperate and tropical climates. The importance of studying antigenic variation of influenza viruses due to the fact that changes in the antigenic structure is an evolutionary mechanism of adaptation of the virus to ensure its survival and cause annual epidemics.Aims. The Aim of this study was to identify the peculiarities of the geographical spread of influenza (seasonal), etiology and the rate of antigenic variability of influenza viruses A and B.Materials and methods. Based on data from WHO Reference research centers, information was collected on circulating influenza virus strains from 1975 A(H3N2), 1977 A(H1N1)pdm09 and type B of the Yamagata and Victoria lines from 1987 to 2019, as well as data on the number of all identified influenza viruses and individual strains circulating in the Northern and Southern hemispheres from 2008 to 2018.Results and discussion. Analysis of the global spread of influenza, its etiology and antigenic variability of viruses, according to WHO, showed that the influenza A(H1N1)pdm09 virus was the main causative agent of epidemics and regional outbreaks in seasons of high influenza activity in all countries except the United States and Canada, where influenza A(H3N2) and B viruses dominated in countries with severe seasonality, the change of season led to a change in the etiology of influenza, and in tropical countries, the A(H1N1)pdm09 virus more often remained dominant in all seasons of the year.Conclusions. The pronounced seasonality of influenza in Northern countries and its absence in tropical countries, where regional outbreaks prevailed in all seasons of the year, were confirmed. Low antigenic variability of influenza A(H1N1)pdm09 strains was confirmed, and the highest – A(H3N2). Among influenza B strains in the Victoria line had less antigenic variability, because the duration of its circulation before the appearance of a new drift variant was longer than that of the Yamagata line. The tendency to increase the total duration of circulation of influenza viruses B/Victoria, A(H1N1)pdm09 and B/Yamagata due to increased circulation before the emergence of new drift variants is shown.
