posibilidad de la incidencia
Authors: Vozza Betina 
Published: February 2022

El presente trabajo pretende compartir algunas reflexiones y muchos interrogantes que surgen de la práctica profesional en un quehacer cotidiano con otros. Las ideas centrales del escrito se vinculan con la necesidad de contextualización de nuestra práctica, es decir, con la ubicación en un determinado contexto socioeconómico y en un ámbito particular de intervención, que nos permita evaluar la incidencia de nuestro abordaje profesional en el marco de la concepción de sujeto a la que adscribimos. Circunscribiéndose a un ámbito específico que interviene en el campo de la infancia y a la luz de algunas experiencias de trabajo se expresan inquietudes surgidas desde las escenas mismas del encuentro con niños atravesados por problemáticas que nos convocan, para arribar a un análisis de los dispositivos que, supuestamente, se crean para «hacer lugar» y para «habilitar».
Entre la codificación de los comportamientos bizarros y el elogio de la locura
Authors: Alberdi José Maria 
Published: February 2022

Este artículo presenta una perspectiva de lectura de la codificación de los comportamientos bizarros y el elogio de la locura en las nuevas instituciones psiquiátricas. A partir del abordaje de algunas escenas institucionales plantea las tensiones y dilemas presentes en los usos de la civilidad en las formas del tratamiento de la locura, teniendo especialmente en cuenta los aportes de Norbert Elias y George Vigarello. En las conclusiones se revisan las aporias de la psiquiatría tradicional y alternativa en sus tareas de tratar y «civilizar» a los locos de los sectores populares.
nueva cuestión social y el arte neoliberal de gobierno
Authors: Murillo Susana Isabel 
Published: February 2022

"La idea de “nueva cuestión social” alude a algunas diferencias substanciales con la denominada “cuestión social” tal como se planteaba a partir del siglo XIX, en nuestro país fundamentalmente a partir de 1869 con la llegada masiva de in- migrantes, momentos en los que la ciudad de Rosario era la segunda ciudad del mundo, después de Chicago, en crecimiento de población (Municipalidad de la Ciudad de Buenos Aires, 1889). Para nosotros, la cuestión social fue conceptualmente hablando de la brecha que se estableció entre los principios planteados por la elite liberal, centrados en la igualda diferencias, ese entramado es el que, con diversidades que ahora no es posible describir, fue constituyendo durante el siglo XX el núcleo de lo que se conoce como “políticas sociales”" (extracto de texto)
Na Prática a Teoria é Outra? Mitos e Dilemas na Relação entre Teoria, Prática, Instrumentos e Técnicas no Serviço Social
Authors: Escurra María Fernanda , De Souza Ribeiro Rafaela 
Published: February 2022

Este libro es gran parte de la tesis de doctorado de Santos defendida en junio de 2006, en la Escuela de Servicio Social de la Universidad Federal de Rio de Janeiro, con el título “Los Instrumentos y Técnicas: mitos y dilemas en la formación profesional del Asistente Social en Brasil”, orientada por la Profesora Doctora Yolanda Guerra.
En la introducción del texto, la autora explica que el interés por el tema deviene de dos afirmaciones usuales en Servicio Social: una, que “la teoría marxista no instrumentaliza para la práctica” y, otra, que “en la práctica, la teoría es otra”. Indica que la relación teoría-práctica es un debate necesario para el Servicio Social y constituye una preocupación presente en el proceso de formación y en la propia práctica profesional. Incluso advierte que, para el Servicio Social, la cues- tión de los instrumentos y técnicas siempre fue problemática y que esta situación viene siendo apuntada tanto por segmentos conservadores de la profesión como por segmentos de vanguardia, lo que genera connotaciones diferentes.
Cuestión social y situaciones problemáticas:
Authors: W. Mallardi Manuel 
Published: February 2022

El presente trabajo expone un conjunto de reflexiones en torno a las mediaciones entre la “cuestión social” y las situaciones problemáticas que se constituyen en el fundamento de procesos de intervención de profesionales del Trabajo Social. La comprensión de la “cuestión social” a partir de las transformaciones en el trabajo dentro de la sociedad capitalista se constituye en el inicio del texto, para luego continuar en la explicitación de las categorías analíticas que vinculan dichos procesos con las situaciones problemáticas.
En este punto, las características que adquiere la categoría situación adquieren relevancia para aproximarnos tanto a los aspectos objetivos y subjetivos de los procesos sociales como a sus determinantes estructurales y expresiones coyunturales.
Fabrication of inverted inorganic–organic quantum-dot light-emitting diodes with solution-processed n-type oxide electron injection layers and QD-polymer blend light-emitting layers
Authors: Itoh Eiji , Yamane Sosei , Fukuda Katsutoshi 
Published: February 2022

Abstract
We fabricated inorganic–organic hybrid quantum-dot light-emitting-diodes (QD-LEDs) consisting of several types of solution-processed n-type oxide electron injection layers (EILs)/quantum-dot (QD) and poly (9-vinylcarbazole) (PVK) blend light emitting layer (EMLs)/4,4-bis(carbazole-9yl)bihpheyl (CBP)/a-NPD/1,4,5,8,9, 11-hexaazatriphenylene-hexacarbonitrile (HAT-CN) hole injection layer/Al structures. We compared the electrical properties of hybrid QD-LEDs with solution-processed n-type oxide electron injection layers consisting of Al-doped ZnO nano-particles (AZO-NP), polyethyleneimine (PEI), titanium oxide nanosheet (TiO-NS) on PEI (PEI/TiO-NS), and AZO-NP/TiO-NS multilayers. The combination of the PEI dipole layer and ultra-thin TiO-NS nanosheet (∼1 nm) layers reduced the potential barrier at ITO/TiO-NS interface. However, a considerable barrier height of >0.3 eV exists at the TiO-NS/QD interface. The use of small-work function AZO-NP (3.9 eV) effectively improves external quantum efficiency (EQE) compared with relatively large work-function AZO-NP (4.3 eV) and TiO-NS (4.1 eV). The capacitance–voltage curves and the current density–voltage–luminance curves strongly depend on the thickness of the QD:PVK blend (2:1 in weight) layer, and we obtained the optimized thickness for EML as ca. 30 nm. With the improved charge balance and morphology, an EQE of above 3.0% is obtained for green light-emitting QD-LED and an EQE of 0.86% for blue light-emitting QD-LED.
Integrated photonic traveling salesman problem probabilistic solver with polynomial calculation time complexity
Authors: Yajima Shun , Shoji Yuya 
Published: February 2022

Abstract
The traveling salesman problem (TSP) is an NP hard problem, where the solution time becomes unrealistically large as the number of points increases. We propose and simulate a photonic integrated circuit-based TSP solver which uses the delay time of light to express the delay caused by traveling between the points. The solver is comprised of semiconductor optical amplifiers and tunable delay lines, therefore it is reconfigurable. A probabilistic algorithm is used, which enables polynomial calculation and footprint complexity with an error rate of less than 1e-12. The calculation time is 388 ms and footprint is within 10 cm squared for a TSP of 100 points.
Emission color modulation of InGaN/GaN multiple quantum wells by selective area metalorganic vapor phase epitaxy on hexagonal windows
Authors: Yoshida Shin , Shojiki Kanako , Miyake Hideto , Uemukai Masahiro , Tanikawa Tomoyuki , Katayama Ryuji 
Published: February 2022

Abstract
We investigated influences of mask pattern on the emission from InGaN multiple quantum wells through the differences in plane orientation appearing on the multifaceted islands in selective area metalorganic vapor phase epitaxy. Cathodoluminescence mapping confirmed that emission colors changed depending on the crystal plane. Photoluminescence spectroscopy showed that the emission wavelength red-shifted by increasing the mask width. By combining the difference of indium incorporation efficiency depending on the crystal plane and the lateral vapor phase diffusion effect, multiple quantum wells with different emission wavelengths of up to 106 nm were grown simultaneously in the microscale region.

Authors: Lokanata Shieny , Sendyra Utama  , Mellisa Sim  
Published: February 2022

Background. This study is an exploration to assess the potential of turmeric extract in the induction of fibroblast cell proliferation, where fibroblast cells are important cells in the process of repair and healing of wounds (socket wounds after tooth extraction). The antioxidants found in turmeric extract are believed to have potential in the initiation of growth factors which will then initiate the process of fibroblast cell activation, which in turn will play a role in wound healing.
Methods. The research design in this study is an experimental study with a post-test-only approach with a control group design. The research subjects in this study were rats (Rattus norvegicus) Wistar strain, male sex, age 8-12 weeks, and body weight between 150-250 grams. A total of 30 white rats were grouped into 5 groups. Data analysis was carried out with the help of SPSS 25 software. First, a univariate analysis was performed to present the mean number of fibroblast cells and the standard deviation. Furthermore, an analysis was carried out to assess the difference in the mean number of fibroblast cells between groups using the one-way ANOVA test.
Results. The results of the one-way ANOVA test showed that there were significant differences between the test groups. Giving 10% and 15% turmeric extract was seen to be more potent in the initiation of the number of fibroblast cells than the treatment group that received povidone-iodine.
Conclusion. Turmeric extract (Curcuma domestica Val.) concentration of 15% was the most effective concentration as an effort to increase the number of fibroblast cells after tooth extraction in Wistar rats.

Abstract

Neutron Star Interior Composition Explorer has a comparatively low background rate, but it is highly variable, and its spectrum must be predicted using measurements unaffected by the science target. We describe an empirical, three-parameter model based on observations of seven pointing directions that are void of detectable sources. Two model parameters track different types of background events, while the third is used to predict a low-energy excess tied to observations conducted in sunlight. An examination of 3556 good time intervals (GTIs), averaging 570 s, yields a median rate (0.4–12 keV; 50 detectors) of 0.87 c s−1, but in 5% (1%) of cases, the rate exceeds 10 (300) c s−1. Model residuals persist at 20%–30% of the initial rate for the brightest GTIs, implying one or more missing model parameters. Filtering criteria are given to flag GTIs likely to have unsatisfactory background predictions. With such filtering, we estimate a detection limit, 1.20 c s−1 (3σ, single GTI) at 0.4–12 keV, equivalent to 3.6 × 10−12 erg cm−2 s−1 for a Crab-like spectrum. The corresponding limit for soft X-ray sources is 0.51 c s−1 at 0.3–2.0 keV, or 4.3 × 10−13 erg cm−2 s−1 for a 100 eV blackbody. These limits would be four times lower if exploratory GTIs accumulate 10 ks of data after filtering at the level prescribed for faint sources. Such filtering selects background GTIs 85% of the time. An application of the model to a 1 s timescale makes it possible to distinguish source flares from possible surges in the background.
Pre-explosive Accretion and Simmering Phases of SNe Ia
Authors: Piersanti Luciano , Bravo Eduardo , Straniero Oscar , Cristallo Sergio , Domínguez Inmaculada 
Published: February 2022

Abstract
In accreting white dwarfs (WDs) approaching the Chandrasekhar limit, hydrostatic carbon burning precedes the dynamical breakout. During this simmering phase, e-captures are energetically favored in the central region of the star, while β-decay are favored more outside, and the two zones are connected by a growing convective instability. We analyze the interplay between weak interactions and convection, the so-called convective URCA process, during the simmering phase of Type Ia supernovae (SNe Ia) progenitors and its effects on the physical and chemical properties at the explosion epoch. At variance with previous studies, we find that the convective core powered by the carbon burning remains confined within the 21(Ne,F) URCA shell. As a result, a much larger amount of carbon has to be consumed before the explosion that eventually occurs at larger density than previously estimated. In addition, we find that the extension of the convective core and its average neutronization depend on the the WD progenitor’s initial metallicity. For the average neutronization in the convective core at the explosion epoch, we obtain

× 10−3 + (9.168 ± 0.677) × 10−2 × Z. Outside the convective core, the neutronization is instead determined by the initial amount of C + N + O in the progenitor star. Since S, Ca, Cr, and Mn, the elements usually exploited to evaluate the pre-explosive neutronization, are mainly produced outside the heavily neutronized core, the problem of too high metallicity estimated for the progenitors of the historical Tycho and Kepler SNe Ia remains unsolved.
Intraday Optical Multiband Observation of BL Lacertae
Authors: Fang Yue , Zhang Yan , Chen Qihang , Wu Jianghua 
Published: February 2022

Abstract
We observed BL Lac in the B, V, R, and I bands with an 85 cm telescope on nine nights from 2019 September 18 to 2019 December 6. More than 2300 data points were collected. All intraday light curves were examined for variations by using the most reliable power-enhanced F-test and the ANOVA test, and intraday variability was found on five nights. Thanks to our high precision and high temporal resolution data, two key discoveries were made in the following analyses. (1) In addition to the strong bluer-when-brighter behavior on most nights, we observed a color reversal that is rarely found in BL Lac objects. This indicates that there are two different energy distributions of injected electrons on this night. (2) The object traced clockwise loops on the color–magnitude diagrams on one night. These are the first intraday spectral hysteresis loops reported in the optical bands in this object, suggesting interband time lags. We estimated the interband lags by using the ZDCF, ICCF, and JAVELIN, and found the variations in the V and R band lagged that in the B band by about 16 and 18 minutes, respectively. Such optical time lags are expected if the acceleration timescale is much shorter than the cooling timescale.
Carbon Monoxide Emission and Spectra Prior to Dust Formation of the Nova V606 Vulpeculae
Authors: Rudy Richard J. , Bayless Amanda J. , Subasavage John P. 
Published: February 2022

Abstract
Visible and infrared spectra, from two, widely separated epochs, are presented for the nova V606 Vulpeculae. The first, acquired 7 days after the nova reached maximum light, displayed emission from carbon monoxide plus a wealth of low excitation atomic lines characterisic of an Fe ii-type novae early in its spectral development. The second, from 80 days later and after additional mass ejection, provided a spectral snapshot of a nova just prior to dust formation. It also was dominated by emission lines of mostly neutral atomic species, many of which included P-Cygni components. However, no spectral features from any molecules were detected, leaving in question what constituted the building blocks of the dust grains that formed shortly thereafter.
Spatial Distribution and Thermal Diversity of Surface Volatile Cold Traps at the Lunar Poles

Published: February 2022

Abstract
The polar regions of the Moon host some of the most extreme low temperatures in the inner solar system due to its low obliquity, lack of atmosphere, and topographic relief. Some of these regions are already confirmed to host water ice. Proposed sources of water and other volatiles include lunar volcanic outgassing, solar wind, and comet impacts. Each of these possible sources would carry a potentially identifiable compositional signature beyond water. Determining the dominant sources of lunar volatiles, therefore, requires assessing the long-term thermal stability of an array of compounds. We present results of mapping the surface thermal stability locations of multiple key volatiles, including water, from the Diviner Lunar Radiometer data from 60° to 90° latitude in both hemispheres. We find the annual maximum temperature for each pixel of interest in the map (∼300 m) to determine which volatiles of interest would be stable there. We report on the thermal stability area of each volatile, as well as the geologic context in some cases. We find that while the thermal stability area for volatiles is larger in the south pole generally, both the north pole and south pole host areas where potential tracer volatiles from lunar volcanism, solar wind, and cometary impacts would be thermally stable for billions of years if such volatiles were ever delivered. We find several areas equatorward of ∼80° on the lunar nearside that could host water ice, where future missions could potentially access volatile deposits in order to place constraints on water delivery to the Moon.

Published: February 2022

The results of a one-year prospective study, during which the process of immunogenesis in patients over 18 years of age with moderate and severe coronavirus infection was monitored and analyzed in clinical and paraclinical (clinical laboratory) aspects, are summarized and presented.
The study included 2683 patients, all treated in the Clinic of Internal Diseases at the University Multiprofile Hospital for Active Treatment and Emergency Medicine “N. I. Pirogov” EAD, Sofia for the period from April 2020 to December 2020. Patients were followed for one year after recovering from moderate to severe coronavirus infection. Patients are grouped into four age categories as follows: 18–45 years; 46–65 years; 66–80 years and over 80 years.
The results of our study show that during the study period in 97% of patients the level of anti-SARS-CoV2, rose and in the remaining three percent it was flat or followed by subsequent waning (in less than 1% of patients), but does not reach critically low levels (i. e. below the positivity conditional threshold). The level of IgG reached a peak and then waned, but on the other hand, as mentioned above, the amount of Ig-Total tested shows a significant increase. This trend is observed in all age groups, with a difference in the level of IgG and Ig-Total depending on age.
The results of the additional screening in the target period in terms of virulence and virus segregation, categorically rule out the suspicion of the presence of “silent spreader”. During the follow-up period, no patients were re-hospitalized due to recurrence of Coronavirus infection (re-infection and illness).
Prevention of thinned wafer deformation during thermocompression bonding and multi-die stacking supported by temporary bonding materials

Published: February 2022

Abstract
Process flows for memory stacking or other heterogeneous integration schemes benefit from die bonding on a thinned silicon wafer 100 μm or less. In scenarios where a thinned device wafer contains features such as microbumps or Cu pillars, a carrier and temporary bonding material (TBM) facilitate the support of the fragile landing wafer during thermocompression bonding (TCB). The landing wafer in this case is vulnerable to deformations including loss of die planarity, Si bulging, Si or low k dielectric cracking, and damage to the underlying device wafer topography.
In this paper, a dual layer system for temporary bonding is presented that maintains the integrity of a thinned device wafer during and after TCB. This is achieved with TBM materials which do not reflow at typical TCB conditions. The approach is to simulate TCB conditions which demonstrate the performance between different underlying TBM materials. A method which tracks the bond head z-axis over time during a TCB cycle is described which in turn yields information on the degree of temporary substrate deformation due to TCB force and temperature. The experiments include a worst-case scenario of multiple TCB cycles in the same position to mimic multi-die stacking. Finally, the impact of process conditions on Cu pillars with solder caps embedded in a thinned wafer bond line will be discussed.
