Value Analysis Model to Support the Building Design Process
Authors: Giménez Zulay , Mourgues Claudio , Alarcón Luis F. , Mesa Harrison , Pellicer Eugenio
Published: May 2020

The architecture, engineering, and construction industry requires methods that link the capture of customer requirements with the continuous measurement of the value generated and the identification of value losses in the design process. A value analysis model (VAM) is proposed to measure the value creation expected by customers and to identify value losses through indexes. As points of reference, the model takes the Kano model and target costing, which is used in the building project design process. The VAM was developed under the design science research methodology, which focuses on solving practical problems by producing outputs by iteration. The resulting VAM allowed the measurement and analysis of value through desired, potential, and generated value indexes, value loss identification, and percentages of value fulfillment concerning the design stage. The VAM permits the comparison of different projects, visualization of the evolution of value generation, and identification of value losses to be eradicated. The VAM encourages constant feedback and has potential to deliver higher value, as it enables the determination of parameters that add value for different stakeholders and informs designers where to direct resources and efforts to enhance vital variables and not trivial variables.
Exploring Environmental and Entrepreneurial Antecedents of Social Performance in Spanish Sports Clubs: A Symmetric and Asymmetric Approach
Authors: Escamilla-Fajardo Paloma , Núñez-Pomar Juan Manuel , Gómez-Tafalla Ana María
Published: May 2020

The social function of non-profit sports clubs is undeniable, so analyzing the factors that influence their performance is vital. The aim of this study is to understand the influence of entrepreneurial factors (entrepreneurial orientation) and environmental factors (dynamism, hostility and complexity) on social performance using a symmetrical (Hierarchical regression model) and asymmetrical (qualitative comparative analysis) approach. The social performance of this particular type of organization is of great importance in an environment where sustainability from a social point of view is increasingly on the agenda of governments, organizations and society in general. A total of 209 Spanish non-profit sports clubs were analyzed. The use of two complementary methodologies has made it possible to highlight the direct positive influence of entrepreneurial orientation (EO) on performance in terms of social impact performance (SIP) and social causes performance (SCP). Similarly, complexity and dynamism have a direct influence on both types of performance, while high levels of hostility in the environment are related to low levels of social performance in both areas. The analysis of the interaction of environmental factors and sport entrepreneurship on social performance in sports clubs has not been previously addressed. Therefore, this study provides new information to elaborate on practical management implications for directors and managers of non-profit sport clubs.
Environmental and Economic Constraints on the Use of Lubricant Oils for Wind and Hydropower Generation: The Case of NATURGY
Authors: González-Reyes Gabriel A. , Bayo-Besteiro Susana , Vich Llobet Jordi , Añel Juan A.
Published: May 2020

Lubricant oil is an essential element in wind and hydropower generation. We present a lifecycle assessment (LCA) of the lubricant oils (mineral, synthetic and biodegradable) used in hydropower and wind power generation. The results are given in terms of energy used, associated emissions and costs. We find that, for the oil turbines and regulation systems considered here, biodegradable oil is a better option in terms of energy and CO2 equivalent emissions than mineral or synthetic oils, from production and recycling through to handling. However, synthetic and mineral oils are better options due to the potential risks associated with the use of biodegradable oil, generally when it comes into contact with water. There are also significant savings to be made in the operation of wind turbines when using an improved type of synthetic oil.
Non-Standard Analysis for Regularization of Geometric-Zeno Behaviour in Hybrid Systems
Authors: Aljarbouh Ayman , Fayaz Muhammad , Qureshi Muhammad Shuaib
Published: May 2020

Geometric-Zeno behaviour is a highly challenging problem in the analysis (including simulation) of hybrid systems. Geometric-Zeno can be defined as an infinite number of discrete mode switches in a finite time interval. Typically, for hybrid models exhibiting geometric-Zeno, the numerical simulation either halts or produces false results, because an infinite number of discrete events occur in a given simulation time-step. In this paper, we provide formal methods for regularization of geometric-Zeno behaviour by using a non-standard analysis. In particular, we provide formal conditions for the existence of geometric-Zeno in hybrid systems, and we propose methods to allow geometric-Zeno executions to be continued beyond geometric-Zeno limit points. The concepts are illustrated with a case study throughout the paper.

Published: May 2020

HEV is the most causative agent of acute viral hepatitis globally. HEV causes acute, chronic, and extrahepatic manifestations. Chronic HEV infection develops in immunocompromised patients such as organ transplant patients, HIV-infected patients, and leukemic patients. The source of chronic HEV infection is not known. Also, the source of extrahepatic manifestations associated with HEV infection is still unclear. Hepatotropic viruses such as HCV and HBV replicate in peripheral blood mononuclear cells (PBMCs) and these cells become a source of chronic reactivation of the infections in allograft organ transplant patients. Herein, we reported that PBMCs and bone marrow-derived macrophages (BMDMs), isolated from healthy donors (n = 3), are susceptible to HEV in vitro. Human monocytes (HMOs), human macrophages (HMACs), and human BMDMs were challenged with HEV-1 and HEV-3 viruses. HEV RNA was measured by qPCR, the marker of the intermediate replicative form (ds-RNA) was assessed by immunofluorescence, and HEV capsid protein was assessed by flow cytometry and ELISA. HEV infection was successfully established in primary HMOs, HMACs, and human BMDMs, but not in the corresponding cells of murine origin. Intermediate replicative form (ds RNA) was detected in HMOs and HMACs challenged with HEV. The HEV load was increased over time, and the HEV capsid protein was detected intracellularly in the HEV-infected cells and accumulated extracellularly over time, confirming that HEV completes the life cycle inside these cells. The HEV particles produced from the infected BMDMs were infectious to naive HMOs in vitro. The HEV viral load was comparable in HEV-1- and HEV-3-infected cells, but HEV-1 induced more inflammatory responses. In conclusion, HMOs, HMACs, and human BMDMs are permissive to HEV infection and these cells could be the source of chronic and recurrent infection, especially in immunocompromised patients. Replication of HEV in human BMDMs could be related to hematological disorders associated with extrahepatic manifestations.

Published: May 2020

Human infections with H7N9 avian influenza A virus can result in severe diseases with high mortality. Developing an effective vaccine is urgently needed to prevent its pandemic potential. Vaccine delivery routes via mucosal surfaces are known to elicit mucosal immune responses such as secretory IgA antibodies in mucosal fluids, thus providing first-line protection at infection sites. PEG-b-PLACL (PELC) is a squalene-based oil-in-water emulsion adjuvant system that can enhance antigen penetration and uptake in nasal mucosal layers with enhanced mucin interactions. In this study, intranasal immunizations with recombinant H7 (rH7) proteins with a PELC/CpG adjuvant, as compared to the use of poly (I:C) or bacterial flagellin adjuvant, elicited higher titers of H7-specific IgG, IgA, hemagglutination inhibition, and neutralizing antibodies in sera, and increased numbers of H7-specific IgG- and IgA-antibody secreting cells in the spleen. Both PELC/CpG and poly (I:C) adjuvants at a dose as low as 5 μg HA provided an 80% survival rate against live virus challenges, but a lower degree of PELC/CpG-induced Th17 responses was observed. Therefore, the mucosal delivery of rH7 proteins formulated in a PELC/CpG adjuvant can be used for H7N9 mucosal vaccine development.

Published: May 2020

The paper is about the development of an automated unit with optimum energy and mass-dimensional parameters for high-quality magnetization of magnets of electromagnetic drives, while preser­ving the integrity of their windings.
The authors develop an approach for calculating amplitude and width of magnetization pulse. The authors than estimate the rise time of leading edge of the pulse, with respect to conditions of complete magnetization of the electromagnetic drive’s magnetic conductor and preservation of its excitation winding integrity.
For the formation of the magnetization pulse with given para­me­ters, the authors propose an electronic device, which feedbacks bitween the drive winding and the pulse current source, which provides power to the inductor winding.
The authors propose a method of the inductor magnetic system synthesis by criteria of: given magnetic field strength in inductor’s operating volume; power supply unit minimal dimensions and it power consumption while magnetizing. The final result is obtaining cross-section profile of the inductor electrical coil with certain dimensions and number of winding’s turns of a wire of certain diameter.
In order to optimize the mass, size, magnetic and energy para­meters of the inductor, the authors solve a problem of synthesizing its magnetic system in way of calculating the parameters of the magnetic field for operating volume of the inductor. It is determined by the characteristic overall dimensions of the NZTB type electromagnetic drives (brakes, 0.2 m in diameter), which were subject to magnetization in a field with strength of at least 400 A/m. The result is the determination of geometrical parameters and the cross-section profile of the inductor electrical coil. This profile ensures the uniformity of the magnetic field when magnetizing the electromagnetic drive of given overall dimensions.
On the basis of all these results, the authors develop the functional scheme of the automated unit and propose a structure of a pa­nel for monitoring and management of devices and units involved.

The control parameters of metal products using the eddy current method of nondestructive testing based on electromagnetic induction law is now widespread. Due to the high sensitivity over a wide frequency range of the ability to control the mechanical properties , uniformity of material, both magnetic and non-magnetic materials, beskonechnosti, high reliability, automation, process control, etc.
The object of study is the process of interaction of external electromagnetic fields with defects in heterogeneity of structure in metal rod, causing a deformation of microtubuli currents and, accordingly, their influence on the inductance coil of the sensor. So, according to the law of electromagnetic induction eddy currents induced by an external electromagnetic field will be asking a private field that will oppose the external field that will lead to a change in inductance of the sensor coil. Therefore, the most informative parameter in this case is the relative change in inductance of the sensor.
In the known designs use differential transformer sensors, transmission type, which differ in complexity of implementation, but have high sensitivity. In existing works not enough attention on improving of the metrological characteristics . Modern means of microstraava flaw detectors in the overwhelming number are for scientific research, but little attention is paid to tools that can be used in industrial processes, through a complex measurement process in the existing funds and the large volume of the software during automatic processing of information.
In the presented work there is a system for nondestructive testing of metal bars with deprivation of the above-mentioned disadvantages, which would provide high metrological characteristics in a wide frequency range, separate measurement of impedance components of the sensor, which allows the reduction of methodological errors of determination of the main characteristics of the output signal of microstraava sensors.
The scientific result is created sambalanco pavement system based on electronic dharamtala model of a vortex sensor with high metrological characteristics, which allows you to create real-time signal proportional to the amount of damage that will give you the opportunity to increase productivity in the quality control bar of metal products in a production environment.
SARS-CoV-2 and Fabry nephropathy: potential risks and the pathophysiological perspective
Authors: Trimarchi Hernán
Published: May 2020

Fabry disease is an X-linked disorder due to mutations in alpha-galactosidase A gene. It affects the kidney in virtually all patients with classical and some late onset variants. Podocytes, endothelial cells, vascular smooth muscle, tubular and mesangial cells are involved in different ways. Proteinuria and chronic kidney disease are the result of the progressive accumulation of the enzyme substrates globotriaosylceramide (GB3) and lyso-GB3 in the cytoplasm of these cells (mainly in lysosomes), which leads to cellular and organ dysfunction and eventually renal failure and end-stage kidney disease. Specific enzyme replacement therapy and pharmacological chaperone are at present the main therapeutic approach. After enzyme infusion, the delivered enzyme is differentially uptaken by kidney cells in three different ways: By Mannose-6-phosphate receptor, megalin and sortilin. The delivered enzyme gradually clears cells from the accumulation of the glycosphingolipids and contributes to a cellular healthier status. The recent pandemic caused by SARS-CoV-2 has led to the collapse of health systems around the world and to thousands of deaths. Kidney involvement has been reported to range from proteinuria to acute kidney injury, 30% of which may require renal replacement therapy. In this review the potential causes for which Fabry patients should be at increased risk and the necessity not to discontinue therapy are discussed.
Are statins toxic or safe for kidney diseases? An updated mini-review study
Authors: Botshekan Shadi , Yalameha Banafsheh
Published: May 2020

Statins, as the most important cholesterol-lowering agents, inhibit the production of blood cholesterol by blocking an enzyme called the 3-hydroxy-3-methylglutaryl coenzyme A (HMG-COA) reductase. Statins have beneficial effects in some tissues during various injuries. Recent evidence suggests that unlike the beneficial effects of statins, administration of high doses of these drugs may increase renal impairment, although more research is needed in this regard. Therefore, this study aimed to evaluate the possible effect of different doses of statins on the morphology and function of the kidney tubular cells.

Introduction: Kidney stones are glycoproteins sediments that are formed inside kidney tubules and collecting ducts and are made of acid crystals and minerals. Objectives: This study aimed to compare the effects of Peganum harmala seed and tamsulosin on pain relief and expulsion of renal and ureteral stones in patients candidate for medical therapy. Patients and Methods: in this randomized clinical trial 80 patients older than 18 years with kidney and ureteral stones sized 4 to 10 mm were randomly allocated to one of two groups by simple sampling method. In group one, after performing ultrasonography and confirming the presence of 4 to 10 mm stone one capsule of tamsulosin 0.4 mg was prescribed per night for two weeks. In group two, harmala seed preparing in form of capsule with dose of 50 mg/kg/d, was prescribed after meal as the same of first group. Two weeks later patients were re-visited and urinary tract ultrasonography was conducted and the change in size of stones and presence of residual stones evaluated and recorded. The severity of pain in the patients was checked using VAS (visual analogue scale). Then the data was collected and analyzed at the end of the study. Results: Mean size of stones after treatment were 4.07±3.66 and 5.15 ± 3.63 mm respectively (P= 0.21). Mean numbers of stones before and after treatment were 0.59±1.38 and 1.18±0.94 (P=0.052). Pain score decreased significantly in both groups which was more significant in P. harmala group (P=0.002). Efficacy of treatment (sum of complete and partial response) in the two groups was 77.5 % and 77.8 % respectively and no significant differences between the two groups were seen (P=0.06). There was no significant side effect in the two groups. Conclusion: This study showed that both P. harmala seed and tamsulosin decrease urinary stone size and numbers without significant difference, but pain score decreased significantly by P. harmala.

Background
. Immediate single implant placement and restoration (IIR) is recognized as a novel method and is the main request of many patients. This study was designed to evaluate the aesthetic outcomes of immediately restored single implants placed in extraction sockets in theanterior maxilla. Methods. In this case series study, 18 patients were selected from two private clinics after placing a single-tooth implant in the anterior maxilla. Immediate provisional crowns were delivered on the following day or at most 48 hours later, and guidelines were provided. The Pink Esthetic Score (PES) questionnaire was used at 6- and 12-month follow-ups to assess aesthetic outcomes. Data were analyzed with single t-test and dependent t-test. Results. In general, the results showed that the status of the mesial papilla, distal papilla, curve of the facial soft tissue line, level of the facial peri-implant mucosa and root convexity soft tissue in IIR method were optimal (P<0.05), with total PES means of 9.44±0.783 and 8.58±1.003 after 6 and 12 months, respectively. Also, the results showed a significant difference in PES between the 6-month and 12-month intervals (P<0.05). Conclusion. IIR is a viable method that resulted in optimal aesthetic outcomes based on PES in the short term. Considering its confirmation in this study and previous studies, it is recommended that dentists apply this method.
Performance of fissure sealants on fully erupted permanent molars with incipient carious lesions: A glass-ionomer-based versus a resin-based sealant
Authors: Jaafar Nada , Ragab Hala , Abedrahman Ahmed , Osman Essam
Published: May 2020

Background. The effectiveness of fissure sealants in caries prevention depends on their long-term retention and ability to stop caries progression. This randomized controlled clinical trial compared the retention rate and cariostatic properties of a contemporary glass-ionomer-based sealant (GIS) versus a resin-based sealant (RS) placed on fully erupted permanent molars in a split-mouth design.Methods.The sealants were placed on fully erupted permanent teeth (8‒12 years of age) in 45 children. The evaluation was conducted after one week and three and six months.Results.There was a statistically significant difference in the retention rate and caries transition between the two groups over a six-month clinical evaluation period. The resin-based sealant group showed a better retention rate than the GIS group (75.56% and 48.88%, respectively). The resin-based sealant was superior to GIS in preventing caries progression.Conclusion.Resin-based fissure sealant with fluoride releasing properties might be preferable in preventing caries progression of incipient non-cavitated carious lesions in fully-erupted teeth.

Development of a novel dental shade determination application
Authors: Kalman Les
Published: May 2020

Determining the shade of dental materials is a challenging requirement for the restorative dentist. Improper shade selection is the second cause for laboratory remakes, resulting in inefficiency and additional cost, and unnecessary stress for the clinician and patient. The process of shade selection is somewhat subjective, with no consensus on the protocol. This research investigation aimed to develop a novel software application to provide an accurate, objective, and systematic approach to shade determination for teeth, soft tissues, and dental materials. An IOS software application was developed, termed Smile Shade, to facilitate a simple approach for dental shade determination. Smile Shade functions on a high-dynamic-range microcolor sensor with automatic temperature control and inter-device repeatability of <1.0 ∆E. The determination of shade is completed through the evaluation of color based on CMYK, RGB, and LAB, which are different techniques of storing colors. Further research is underway to compare this novel application to the traditional shade tab approach commonly practiced at most dental schools.

Published: May 2020

Background: Non-suicidal self-injury (NSSI) has become one of the serious public health concerns among adolescents. Factors like family and social environment of adolescents may be important determinants of the NSSI. This study aimed to investigate the relationship between family psychological function and perceived social support with the NSSI experience among adolescents. Study design: A cross-sectional study. Methods: Overall, 4216 high school students (15-18 yr old) of Tabriz City, northwestern Iran were selected using multi-stage cluster random sampling method in October and November 2017. Participants completed survey including demographic characteristics, NSSI status, Iranian family psychological function, and perceived social support. After six months, NSSI status was reassessed. The data were analyzed using logistic regression model. Results: 8.5% of the students had NSSI experience. In addition, the weak family psychological function increased the odds of experiencing the NSSI by 13 times compared to the strong psychological function (OR = 13.15, 95% CI: 7.19, 23.80). Besides, the low level of perceived social support increased the odds of experiencing the NSSI by about 7 times compared to the high perception of social support (OR= 6.67, 95% CI: 4.01, 11.11). Conclusion: Low levels of psychological functioning of the families and perception of social support significantly can increase the odds of experiencing the NSSI among adolescents. Therefore, special attention should be paid to these factors in the development of relevant preventive programs in adolescence period.

Published: May 2020

The reaction of the world’s large ice sheets to global climate change is still in the focus of scientific debate. Recent investigations have shown pronounced thinning in the southern part of the Greenland ice sheet (Inland Ice). In order to investigate the cause of the observed thinning and to judge the sensitivity of this part of the ice sheet a combined field work, remote sensing and modelling project was designed. A glaciological transect was established in May 2001 on one of the main outlet glaciers in South Greenland (Fig. 1), and the first data are now available. In addition, the history of the glacier variations during the last 40 years has been reconstructed.
Groins, sand retention, and the future of Southern California’s beaches
Authors: Griggs Gary , Patsch Kiki , Lester Charles , Anderson Ryan
Published: May 2020

Beaches form a significant component of the economy, history, and culture of southern California. Yet both the construction of dams and debris basins in coastal watersheds and the armoring of eroding coastal cliffs and bluffs have reduced sand supply. Ultimately, most of this beach sand is permanently lost to the submarine canyons that intercept littoral drift moving along this intensively used shoreline. Each decade the volume of lost sand is enough to build a beach 100 feet wide, 10 feet deep and 20 miles long, or a continuous beach extending from Newport Bay to San Clemente. Sea-level rise will negatively impact the beaches of southern California further, specifically those with back beach barriers such as seawalls, revetments, homes, businesses, highways, or railroads. Over 75% of the beaches in southern California are retained by structures, whether natural or artificial, and groin fields built decades ago have been important for local beach growth and stabilization efforts. While groins have been generally discouraged in recent decades in California, and there are important engineering and environmental considerations involved prior to any groin construction, the potential benefits are quite large for the intensively used beaches and growing population of southern California, particularly in light of predicted sea-level rise and public beach loss. All things considered, in many areas groins or groin fields may well meet the objectives of the California Coastal Act, which governs coastal land-use decisions. There are a number of shoreline areas in southern California where sand is in short supply, beaches are narrow, beach usage is high, and where sand retention structures could be used to widen or stabilize local beaches before sand is funneled offshore by submarine canyons intercepting littoral drift. Stabilizing and widening the beaches would add valuable recreational area, support beach ecology, provide a buffer for back beach infrastructure or development, and slow the impacts of a rising sea level.

“Nuevo Sindicalismo" y Represión Judicial en el Brasil de la “apertura”: las huelgas metalúrgicas en São Bernardo do Campo y São José dos Campos (1980-85)
Authors: De Oliveira Martins Richard
Published: May 2020

En el presente texto, tratamos de algunas de las diferentes modalidades de represión judicial con que se depararon liderazgos y activistas metalúrgicos como consecuencia de su participación en los movimientos huelguistas que marcaron el período de la llamada "apertura política" brasileña. Partimos del fracaso del intento de criminalización de algunos de los dirigentes metalúrgicos de São Bernardo do Campo/SP, tras la huelga que condujeron en 1980, enjuiciados en la Ley de Seguridad Nacional. Años después, ya bajo Sarney, cuando activistas y sindicalistas metalúrgicos de São José dos Campos/SP también fueron procesados criminalmente como resultado de su participación en una huelga con ocupación de fábrica, la nueva LSN aprobada en 1983 no fue movilizada; la represión promovida por el Gobierno provincial de San Pablo contra los huelguistas se amparó en artículos del Código Penal, en un evidente intento de caracterizarlos como simples criminales. Sostenemos que esta táctica de represión judicial tenía la intención de deslegitimar la huelga, ocultando el carácter también político de la represión.
Construir un enemigo en tiempos de neutralidad: anticomunismo y disciplinamiento detrás de los debates por el derecho de reunión en Argentina (1938-1943)
Authors: López Cantera Mercedes F.
Published: May 2020

El despliegue de la represión estatal en la Argentina realizado por la Policía de la Capital en los años treinta y en los tempranos cuarentas encontró en el llamado “enemigo comunista” un sujeto en base al cual el Estado pudo especializar y delinear distintas estrategias de disciplinamiento, que tuvieron como principal objetivo al movimiento obrero. Partiendo de esta premisa y ubicándonos en el contexto que generó el impacto de la Guerra Civil española y los comienzos de la Segunda Guerra Mundial, junto a las políticas de prescindencia y de neutralidad adoptadas por los gobiernos del período, nos proponemos analizar aquellas medidas que esa fuerza policial impartió en relación al control sobre las reuniones públicas con el objetivo de caracterizar a la lógica anticomunista presente en las herramientas de disciplinamiento dispuestas a fin de la gestión de Agustín P. Justo (1932-1938) y durante la de Roberto Ortiz y Ramón Castillo (1938-1943). Con esos objetivos abordaremos los distintos edictos policiales sobre reuniones públicas y las discusiones en torno a la aplicación de los mismos que tuvieron lugar en el Poder Legislativo, donde serán centrales las interpelaciones solicitadas por la Cámara de Diputados al Ministro del Interior Miguel Culaciati, y las diversas acciones de represión impartidas sobre el movimiento obrero entre 1938-1943 desde la Sección Especial de Represión contra el Comunismo de la Policía de la Capital.
“Con una metralleta en la cabeza este país trabaja”, Represión estatal en contra de los trabajadores durante la dictadura cívico militar chilena (1973-1990)
Authors: Araya Gómez Rodrigo
Published: May 2020

El artículo tiene por objetivo analizar las distintas expresiones de la represión ejercida por la dictadura cívico-militar encabezada por el general Augusto Pinochet en contra de los trabajadores y sus organizaciones, considerando a tales efectos, las políticas diseñadas por los órganos encargados de la legislación laboral, incluyendo entre estas la Dirección del Trabajo y el Ministerio del Trabajo. De esta forma, la dictadura tuvo una orientación antisindical destinada a consolidar la aceptación del modelo neoliberal en la población a través del miedo o la resignación, a pesar de los costos sociales de la aplicación de él mismo, que implicaron un deterioro de las condiciones de vida de amplias capas de la sociedad.
“Si va hablando solo por la calle: trabaja en Dálmine”. La salud obrera como campo de disputa en una gran empresa siderúrgica: entre la resistencia de los trabajadores y las prácticas de violencia estatal y empresarial (1974-1978)
Authors: Peláez Pablo
Published: May 2020

El artículo propone analizar un conflicto laboral suscitado entre 1974 y 1978 en una de las empresas con mayor cantidad de víctimas trabajadoras y sindicalistas durante el terrorismo de estado: la siderúrgica Dálmine-Siderca, ubicada en Campana y perteneciente al grupo Techint. La disputa tuvo como eje las condiciones de insalubridad laboral, en un contexto determinado por la ampliación de la planta industrial y la represión extrema sufrida por el colectivo obrero de la fábrica.La reconstrucción del entramado conflictivo nos permite realizar un primer avance en un campo de estudios poco desarrollado en la historiografía, relativo a las disputas específicas por la salud y las condiciones de trabajo en las fábricas, y encontrar líneas explicativas que contribuyan a identificar algunas de las razones de aquella represión particularmente intensa.El trabajo consta de cuatro apartados, en los que se desarrollan un breve estado de la cuestión sobre la temática, un recorrido por las condiciones de trabajo en la acería de la planta, una aproximación empírica al conflicto y la dinámica represiva, y algunas reflexiones generales. Utilizamos una amplia variedad de fuentes: balances y publicaciones empresarias, expedientes del Ministerio de Trabajo, legajos de inteligencia, prensa local y testimonios de ex trabajadores.
La relectura de la historia como instrumento de construcción de la identidad: los jesuitas y Rosas
Authors: Gómez Diez Francisco Javier
Published: May 2020

Si desde su origen la Compañía de Jesús recurrió a la narración de su propia historia como instrumento para configurar su identidad, la tarea resultó de especial importancia en el siglo XIX, al enfrentarse a tres dificultades nuevas: interpretar la supresión total de la orden, decretada en 1773 por Clemente XIV; responder al orden político nacido de la revolución burguesa y entrar en relación con novedosos ideales culturales y científicos. Si desde el primer momento muchos jesuitas, por propia iniciativa, narran sus viajes, experiencias y misiones, a medida que avanza el siglo XIX este esfuerzo se institucionaliza y se dota de una pretensión científica que busca también ser reconocida fuera de los círculos de la Compañía. El artículo se aproxima a esta problemática analizando la relectura de la misión de Buenos Aires durante la presidencia de Juan Manuel de Rosas; relectura que, a partir de la crónica de Mariano Berdugo (1841), realizan los jesuitas José J. Cotanilla, Rafael Pérez, Pablo Hernández, Juan Isérn, Joaquín Gracia y Guillermo Furlong. Analizo las razones que impulsan la redacción histórica y, desde aquí, busco establecer la inserción identitaria de la Compañía restaurada.

El presente dossier se propuso aportar a este campo de estudios reuniendo investigaciones que abordaran diversas experiencias de coordinación el trabajo de solidaridad y denuncia de las violaciones de los derechos humanos durante el último ciclo de dictaduras de Seguridad Nacional en el Cono Sur, con énfasis en las redes transnacionales de defensa de derechos humanos. Así que, concibiendo estas redes como los contactos y cooperaciones establecidas entre actores situados en diversas geografías, vinculando sus luchas por valores compartidos, convocamos trabajos que ya sea centrándose en escenarios locales, reconstruyendo trayectorias, o abordándolo desde una perspectiva de circulaciones, intentaran desentrañar el funcionamiento de diversos tipos de redes interpersonales e interorganizacionales que favorecieron ese proceso de “transnacionalización de una causa” (Keck y Sikkink, 2000).Tomando como marco temporal aquel desde el golpe de Estado en Brasil hasta el retorno de la democracia en Chile, el dossier “Redes transnacionales de defensa de los derechos humanos en América Latina (1964-1990)” se compone de cinco artículos de investigación histórica. Tres de ellos fueron debatidos en un panel del III Coloquio Internacional sobre Violencia Política en el Siglo XX-IV Jornadas de Trabajo de la Red de Estudios sobre Represión y Violencia Política (RER) que tuvo lugar en la Facultad de Humanidades y Artes de la Universidad Nacional de Rosario del 24 al 26 de abril de 2019. Para ampliar y complejizar el análisis con casos escasamente estudiados, convocamos otras dos colaboraciones originales de especialistas en la problemática de Brasil y Francia.

Published: May 2020

Objetivo: relatar a terapêutica adotada em um caso de neoplasia peritoneal metastático que não obteve o sítio primário localizado por métodos convencionais diagnósticos. Metodologia: trata-se de um estudo do tipo descritivo, com abordagem qualitativa, baseado em estudo de caso, realizado a partir de pesquisa em prontuário como instrumento para coleta de dados. A pesquisa obedeceu aos princípios éticos, em conformidade com a resolução 466/2012, do Conselho Nacional de Saúde, que trata de pesquisa e testes envolvendo seres humanos. O projeto foi submetido e aprovado pelo Comitê de Ética em Pesquisa da Faculdade Santa Maria. Resultados: com um quadro clínico inicial bastante inespecífico foi necessário a realização de diversos exames, tanto laboratoriais quanto de imagem, para a investigação dos diagnósticos diferenciais, neoplásicos ou não, que poderiam acometer o peritônio, até se firmar o diagnóstico como carcinomatose peritoneal metastático, porém, sem a confirmação da origem da lesão. O caso foi conduzido com terapêutica direcionada para a metástase, enquanto continuava-se a realizar uma gama de exames para investigação do foco primário do tumor, o que poderia aumentar a eficácia do tratamento, desde que houvesse uma conduta mais direcionada ao foco principal da lesão tumoral. Conclusão: foi relatado o caso demonstrando que mesmo com uma longa jornada investigativa não se obteve desfecho diagnóstico. A principal hipótese aceita para o caso em questão foi a de tumor primário do próprio peritônio. Prolongou-se por pouco tempo a sobrevida do paciente, que veio a óbito cerca de 1 ano e 6 meses após o início da sintomatologia.

Derecho al olvido frente a la pena en el derecho penal
Authors: Zabala Puchana Oscar David
Published: May 2020

Un aforismo muy famoso dice que el tiempo lo cura todo, pero no es solamente el paso del tiempo el que nos ayuda a superar una situación, sino el mismo olvido, ya que en muchas circunstancias de la vida se vuelve mucho más fácil olvidar que perdonar; ya pertenece a la costumbre social tener una memoria corta en muchas de las situaciones, momentos o vivencias, lo cual hace mucho más fácil vivir en sociedad; sería muy complicado estar recordando cada suceso malo de la vida e intentar olvidarlo para que no sea una carga. Lo anterior no solo en el aspecto personal, sino en el social, porque el no hacerlo genera situaciones catastróficas y perjudiciales para el avance de un conglomerado y un desarrollo en comunidad.

The proposed system uses deep neural networks for identifying bird species. The model will be trained on bird images that are coming in the endangered species category. The application can also handle new data points, unlike existing systems that require model re-training for accommodating new data. The system can identify bird species in a large view of the image. The model will be trained using a convolutional neural network-based architecture called Siamese Network. This network is also called one-shot learning which means that it requires only few training example for each class. Existing models use image processing techniques or vanilla convolutional neural networks for classifying bird images. These models cannot accommodate new images and have to be retrained to do so. There is no commercially available system that can detect a species of bird in high resolution / large image. While in the Siamese network we only have to add new data, there is no need to retraining the neural network.
