“El espíritu de Francia” (1898). Presentación y edición de un artículo desconocido de Rubén Darío
Authors: García Morales Alfonso
Published: April 2021

En julio de 1898 la parisina Revue des Revues publicó una “enquête” realizada a destacados intelectuales franceses sobre si existía una identidad o “espíritu francés” distinguible en su literatura y sobre la posibilidad de que los escritores extranjeros pudieran asimilarlo. Dos meses después Rubén Darío se sumó por su cuenta a la encuesta y respondió en “El espíritu de Francia”, un artículo publicado en el semanario El Sol del Domingo de Buenos Aires y desconocido hasta hoy, en el que reafirmó de manera inequívoca su “galicismo mental”, su identificación con la modernidad universal representada por Francia y su derecho de reconocimiento y pertenencia a la República mundial de las letras con centro en París. El texto que aquí se presenta y anota es una pieza más del todavía incompleto rompecabezas textual de Darío, y arroja nueva luz sobre un momento particular de su relación con la “patria intelectual” francesa, asunto central de su discurso crítico y de la construcción de su lugar como escritor
Borges y la vanguardia de los años 20: tres libros desterrados
Authors: Fuente Pérez Luis
Published: April 2021

A la muerte de Jorge Luis Borges reapareció al fin la que podríamos llamar su “obra invisible”: tres libros de ensayos de los años 20 cuya reedición prohibió tajantemente en vida. A lo largo de estas páginas nos propondremos indagar en el contexto y los motivos que llevaron a la escritura de estos volúmenes, así como en los temas e intereses que en ellos se entretejen, los cuales serán la simiente de muchas de las cuestiones que fascinen al futuro Borges. De esta forma, buscaremos apreciar la obra borgiana en su continuidad y entender las posibles razones que provocaron el destierro de esos textos de la nómina canónica del argentino hasta su muerte.
La recepción de García Márquez en China: desde la Revolución Cultural a la “literatura de la búsqueda de las raíces”
Authors: Gao Weiqian
Published: April 2021

La recepción crítica y la influencia literaria de García Márquez en la literatura contemporánea china han permanecido sumidas durante mucho tiempo en un inmerecido olvido, pues tanto el mundo intelectual hispánico como el chino han tardado en considerar este tema objeto digno de estudio. Con el presente trabajo procedemos, por un lado, a diseccionar, analizar y presentar la recepción crítica del Nobel colombiano en el mundo literario chino; y a examinar, por el otro, cómo las novelas garciamarquianas influyen sobre la creación narrativa de los escritores chinos de la “literatura de la búsqueda de las raíces”.

Authors: Chu Hsiao-Ping , Chang Tsangyao , Sagafi-nejad Tagi
Published: April 2021

This paper revisits the nature and direction of causation between globalization and economic growth in nine OECD countries and China by applying the bootstrap panel Granger causality test to the data over the period of 1981-2008. Empirical results support evidence on causality from globalization to economic growth for Netherlands and the UK; causality from economic growth to globalization in the US, neutrality for Australia, Belgium, Canada, France, Italy, and Japan. Based on the empirical results from this paper, we provide important policy implications for the OECD countries and China.

Published: April 2021

Objectıve: Acute Kidney Injury (AKI) and subsequent renal failure are the leading causes of morbidity and mortality in the intensive care unit (ICU). In this study, it was planned to compare Neutrophil Gelatinase-associated Lipocalin (NGAL) and creatinine values in patients diagnosed with AKI and to determine the effect of renal dose dopamine use on renal blood flow, development of chronic renal failure (CRF) and mortality. Materıals and methods: This prospective study was planned with 35 patients developed AKI in the ICU of Bakırköy Dr. Sadi Konuk Training and Research Hospital. The patients were randomized into 2 groups as 18 patients who received dopamine treatment with the recommendation of the cardiology clinic and 17 patients who did not receive dopamine treatment. Urea, creatinine and NGAL plasma levels were compared between groups. Results: There was no difference between the groups in terms of age, gender and AKI stage. The 0th, 24th hour results and 24-hour changes of urea, creatinine and NGAL values of dopamine patient, who took dopamine, were found to be similar to those of patients who did not take dopamine. A significant positive correlation was found between the 24-hour change in creatinine value and the 24-hour change in NGAL (r=0.374; p<0.05). There was no significant change in the diameter and flow of renal arteries between measurements in patients who received dopamine. The rates of patients who regain normal kidney functions, develop CRF or develop mortality between the two groups were found to be similar. Conclusıon: Treatment results of AKI developing in ICU are not satisfactory. Low-dose dopamine treatment has no effect on patient outcomes in these patients. NGAL is a biomarker that has the ability to show renal damage at an early stage. Serial measurement of NGAL concentration during ICU stay may benefit the clinician in early diagnosis and follow-up of AKI.

Authors: Yılmaz Serhan , Bölükbaşı Hakan , Bozkurt Mehmet Abdussamet
Published: April 2021

PURPOSE: The aim of this study is to determine risk factors for malignancy in gallbladder polyps. METHODS: 92 patients who underwent laparoscopic cholecystectomy due to gallbladder polyp were retrospectively analyzed. Demographic data of the patients, size and number of polyp, the presence of gallstones and histopathological features of the polyps were recorded. RESULTS: 92 patients were included. Mean age was 45.78±11.21 years (21-72). 59 of the patients (64.1%) were female and 33 (35.9%) were male. Mean polyp size was 8.17±2.19 mm and 35 patients (38.0%) had a single polyp, while 57 (62.0%) had multiple polyps (≥2). 47 of the patients (51.1%) had gallstone disease, while 45 (48.9%) had no stone disease. Benign polyps (Group 1) were found in 79 patients (85.9%) and adenocarcinomas (Group 2) were found in 13 (14.1%). Of the benign polyps, 71 (77.1%) were non-neoplastic polyps and 8 (8.8%) were neoplastic polyps (adenomas). Of the 13 patients with adenocarcinomas, 11 (11.9%) were T1a and 2 (2.2%) were T1b. Mean age was 44.32±11.03 years in Group 1 and 54.61±8.07 years in Group 2, the latter being significantly older (p=0.002). Mean polyp size was 7.47±5.51 mm in Group 1 and 12.46±1.89 mm in Group 2, with a significant difference (p<0.001). The cut-off value to detect malignant polyps was a polyp size of 10.5 mm with 92.3% sensitivity, 84.8% specificity, and 0.934 accuracy (p< 0.001). The cut-off value to detect malignant polyps was an age of 50.5 years with 76.9% sensitivity, 67.1% specificity, and 0.767 accuracy (p=0.002). Polyp size and age were important risk factors for malignant gallbladder polyps (p<0.001, OR=2.313; 95% CI: 1.502–3.561), (p=0.004, OR=1.100, 95% CI: 1.030–1.175). CONCLUCISION: We recommend cholecystectomy for asymptomatic patients aged above 50 years with gallbladder polyps larger than 10 mm due to the increased risk of malignancy.

Authors: Alanlı Recep , Küçükay Murat Bülent , Yalçın Kadir Serkan
Published: April 2021

Background: The aim of the study is to inspect effectiveness of lactate dehydrogenase (LDH) to albumin ratio (LAR) in patients with pulmonary thromboembolism (PTE). Methods: In this single center and retrospective study, 307 patients who admitted to emergency unit, between January 2017 and March 2020, with chest pain and sudden developing dyspnea were enrolled. Computed tomography pulmonary angiogram (CTPA) were performed to confirm pulmonary embolism. Results: LAR, neutrophil, monocyte, d-dimer, LDH values were significantly higher and albumin values were significantly lower in patients with pulmonary embolism compared to patients without pulmonary embolism. Average age of 307 participants were 68.93; 140 patients were confirmed for PTE and 167 were normal. Linear regression analysis for LAR in diagnosis of PTE, revealed a correlation coefficient as r=0.320 (p<0.001). Positive and negative predictive values for LAR in diagnosisi of PTE were, 63.3% and 75.2%, respectively. In ROC analysis relation of LAR to PTE was found to be stronger than LDH and albumin tests alone. Conclusion: LAR, which is a very simple and available test, may be used as a novel parameter in diagnosis of PTE.

Published: April 2021

Objective: This study investigated the clinical utility of a “forensic staging system” for iliac crest apophysis ossification widely used in idiopathic scoliosis patients. Method: Radiographs of 98 scoliosis patients (76 females, 22 males; age range: 5–24 years) were examined and 196 iliac crest apophyses were evaluated. Results: The forensic staging system has four stages, with substages for stages 2 (2a–c) and 3 (3a–c). Of the 196 iliac crests evaluated, 65 were stage 2 (Risser stage 4–5) and 6 were stage 3 (Risser stage 5). Conclusion: The forensic staging system for iliac crest apophysis provided more detailed clinical follow-up data. Studies with larger series may help to improve the forensic staging system.
La política criminal del nudge. Algunos desafíos del Análisis Conductista a las teorías del Derecho Penal tradicionales
Authors: Moreno Cruz Diego
Published: April 2021

La objeción de Harel y Teichman en contra de que los gobiernos sigan las “recomendaciones de política pública provenientes de los teóricos conductistas”, para llevar a la gente a obedecer las reglas penales y, de este modo, para prevenir la ocurrencia de crímenes, puede ser entendida como cuestiones acerca de la permisibilidad ética y la utilidad práctica de aplicar lo que llamaré “política criminal del nudge”. Mi propósito en este escrito no es ofrecer una definición exhaustiva de este tipo de política pública ni tampoco justificar su uso desde una perspectiva ética, sino tan solo enunciar algunos retos a las teorías tradicionales del derecho penal en las que Harel y Teichman asientan su objeción.

El rol de las virtudes en el republicanismo
Authors: Richter Anna
Published: April 2021

En su libro, Razones públicas, Rosler analiza seis conceptos bá- sicos de la república y del republicanismo clásico, la libertad, la virtud, el debate, la ley, la patria y, como antagonismo al republicanismo, el cesarismo. Propone investigar no solo qué se entendía por esos conceptos en el republicanismo clásico, sino también qué rol cumplirían en nuestras sociedades contemporáneas. En el presente trabajo se pretende indagar un poco más en esa supuesta utilidad de las virtudes para las sociedades contemporáneas, y eso a partir de los siguientes interrogantes: ¿se pueden trasladar las exigencias de virtuosidad del republicanismo clásico a nuestros tiempos? Y ¿qué significarían tales exigencias ahora? Estas preguntas se pueden agrupar en dos ejes: primero habría que establecer cuáles virtudes se necesitarían en una república contemporánea y en segundo lugar habría que analizar en qué momento o instancia de la vida republicana cobran relevancia.
Política y autoridad en Bernard Williams

This study examines the length of the estrous cycle in 16 Sambar deer hinds in National zoological gardens in Dehiwala and Kegalle, Sri Lanka (NZGDK) assessed with the use of changes in progesterone concentrations, along with the changes in the profile of this hormone and by the visual estrus manifestations. The objectives of the present study were to characterize ovarian activity throughout the estrous cycle and the non-pregnant luteal phase of captive sambar deer in Sri Lanka. These objectives were achieved with the use of radioimmunoassay (RIA) to measure fecal concentrations of progesterone and visual estrus manifestation. Fecal samples were collected from non-pregnant sambar deer hinds (aged 2–4 years)over the period of six months on daily basis, both during breeding and non-breeding seasons. Estrous cycles were recorded in non-pregnant females, based on fecal progesterone concentrations. The average estrous cycle length was 26.1±2.08 days (mean ± SEM) and 2.10 ± 0.51 days in the inter-luteal phase.The average fecal progesterone concentrations attained the peak mid-luteal values of 2.74 ng mL–1. There appeared to be variation in fecal progesterone amplitude between animals and between dates, but the low frequency of sampling prohibited confirmation of trends. Behavioral estrus was detected only when the average progesterone concentrations were less than 0.07 ng mL–1. However, not all periods of depressed progesterone secretion were associated with the observed estrus. Behavioral estrus was detected in hinds when progesterone concentrations were less than 0.07 ng mL–1; a subsequent rise in progesterone indicated ovulation taking place at this time.

Published: April 2021

The Covid-19 pandemic has had an impact on the Indonesian economy. The purpose of this study was to analyze the causality and balanced relationship in the long term between RR, IR and INF variables during the Covid-19 pandemic. With the Granger Causality and Johansen Cointegration test methods, the results showed that there is a long-term balance between RR, IR and INF. RR and IR are one-way causality relationships, IR and INF are one-way causality relationships. There is no causality relationship between IR and RR and vice versa during the Covid-19 pandemic. The RR policy affects the determination of IR and IR affecting Indonesia's INF during the Covid-19 pandemic. To reduce the inflation rate during the pandemic, Bank Indonesia needs to implement RR policy through the determination of interest rates.

Effect of Sugarcane Bagasse Ash as Partial Cement Replacement on the Compressive Strength of Concrete
Authors: Ali Sabir , Kumar Aneel , Rizvi Samar Hussain , Ali Mohsin , Ahmed Israr
Published: April 2021

The disposal of solid waste in open environment is a serious alarming concern that needs immediate attention from the researchers. The hazardous solid agro-industrial wastes which include: wheat straw ash, rice husk ash, corn cob ash and sugarcane bagasse ash (SCBA), having pozzolanic properties, have a versatile use in concrete. The solid pozzolana enhances the various concrete properties by the reaction of silicates with calcium hydroxide in the presence of water, which in result generate a saturated zone of calcium silicate hydrate (CSH) gel. This C-S-H gel reduces the amount of calcium hydroxide C(OH)2 during the hydration process of cement. Very limited research works have been done on concrete by partially replacing cement with SCBA. This research work was focused on evaluating the properties of concrete by partially replacing cement with SCBA at 0, 5, 10, and 15 percentages. Compressive strength, Strength activity index, and water absorption of all mixes were examined. And it was observed that all SCBA mixes showed an increase in compressive strength and at 10% replacement the strength activity index was at a peak of 115.67%, but all the SCBA mixes showed a strength activity index greater than 75% which satisfied the standard specification. The water absorption test for all SCBA mixes showed a slight increase in water absorption.

Published: April 2021

In this study, the quality of groundwater used for drinking purposes at Rajanpur Tehsil Pakistan is investigated. Water contamination causes several health problems to human being and the severity of problems mainly depends upon the level of pollutants present in water. Physical, chemical, and biological parameters of groundwater for twelve locations are analyzed using standard procedures. The obtained results are compared with the standards set by WHO. Most of the chemical parameters are found within the WHO standards except Arsenic, Calcium, and Sulfate at various locations. The Arsenic is found beyond WHO standards at nine locations with an increased percentage of 400% at three locations namely village Mehre Wala, Sehnwal, Near Basti Bhayan, and is also found beyond the permissible limit, i.e., upto 150% at six locations Sikhaniwala, Kot Mithan, Basti Nazru, Basti Asni, Jalal Pur, and Qutab Pul. Only three locations show satisfactory results, namely village shikarpur, village Murghai and Basti Lakha. The percentage of calcium at five locations such as Murghai, Basti Nazru, Basti Asni, Basti Lakha, and Chak Jalal Pur (Pull Pathan) is found to be 44%, 12%, 17.33%, 76%, and 49.33%, which is much higher than the WHO standards. Meanwhile, the Sulphate is also found to be beyond WHO standards at four locations, i.e. 30.8% for Mehrewala, 37.6% for Murghai, 34.8% for Basti Lakha and 34% for Chak Jalal Pur (Pull Pathan). Biological contamination including total coliform and fecal coliform are found to be beyond the limit at Sehanwala, Rangpur, Shikarpur, and Basti Nazru locations. The higher percentage of Arsenic, calcium, and sulfate in water indicate that the groundwater is not suitable for drinking purpose. Sustainable water treatment is highly recommended for drinking water at the identified contaminated location.

Published: April 2021

Arsenic is a carcinogenic element capable to get into water bodies and drinking water supplies from natural deposits and industrial practices. Its presence in drinking underground water is highly toxic to human health. The study is focused on the development of indigenous Iron-Coated Pottery Granules (ICPG) to remove As from groundwater of Hala City. The developed ICPG was agitated with local clay white flour and water. A low-cost adsorbent namely ICPG was synthesized for the expulsion of As from underground water. The ICGP was characterized with SEM and FTIR techniques. Furthermore, the impact of physical parameters including adsorbate concentration, dosage, mixing time, pH, and contact time on As removal efficiency was investigated in batch experiments. The maximum removal efficiency was achieved with an adsorbent dosage of 0.5 grams at pH =7 for a contact time of 90 minutes when agitated at a speed of 150 r/min. The arsenic removal efficiency was found highly dependent on contact time increase and optimum pH (maximum removal achieved at strong adsorption of As at pH 4–7), however, the rise of adsorbate concentration resulted in the decrement in the efficiency after certain range. Batch adsorption study of underground water sample collected from Hala, Sindh, Pakistan was performed with satisfactory results, i.e. 94 arsenic removal from water. All the water samples were analyzed through atomic absorption Spectrophotometer. The investigation has indicated that ICPG is an exceptionally favourable material for As removal from drinking underground water and can be applied to handle the arsenic issue in most of the regions of Sindh province.

Published: April 2021

Solving the root of algebraic and transcendental nonlinear equation f' (x) = 0 is a classical problem which has many interesting applications in computational mathematics and various branches of science and engineering. This paper examines the quadratic convergence iterative algorithms for solving a single root nonlinear equation which depends on the Taylor’s series and backward difference method. It is shown that the proposed iterative algorithms converge quadratically. In order to justify the results and graphs of quadratic convergence iterative algorithms, C++/MATLAB and EXCELL are used. The efficiency of the proposed iterative algorithms in comparison with Newton Raphson method and Steffensen method is illustrated via examples. Newton Raphson method fails if f' (x) = 0, whereas Steffensen method fails if the initial guess is not close enough to the actual solution. Furthermore, there are several other numerical methods which contain drawbacks and possess large number of evolution; however, the developed iterated algorithms are good in these conditions. It is found out that the quadratic convergence iterative algorithms are good achievement in the field of research for computing a single root of nonlinear equations.
SAPO – en modell för samverkan mellan forskare och aktörer utanför akademin inom området äldre och åldrande
Authors: Jönson Håkan , Hultqvist Sara , Iwarsson Susanne
Published: April 2021

Den åldrande befolkningen har identifierats som en samhällsutmaning. En tydlig utveckling inom forskning om sådana utmaningar är krav på medverkan från patientgrupper, brukarorganisationer och andra aktörer utanför akademin.
Syftet med artikeln är att introducera en modell för utformning och värdering av samverkan mellan akademiska forskare och aktörer utanför akademin. Modellen bygger på en genomgång av internationellt etablerade traditioner och ramverk för sådan samverkan och ramas in av komponenterna syfte, aktör, process och omfattning (SAPO) eller enklare uttryckt genom frågorna: varför, med vem, när och hur mycket?
Med hjälp av modellen kan både forskare och aktörer utanför akademin föra mer systematiska och kritiskt värderande resonemang om samverkan. Det kan i sin tur leda till effektivare arbetsformer och nyttiggörande av resultat från det mångfasetterade forskningsområde som rör den åldrande befolkningen.
 
SAPO (PAMP) – a model for collaboration between researchers and external actors wihin the field of ageing studies
The ageing population has been identified as a societal challenge and it has been strongly emphasized that service users, interest groups and other actors that are external to academia should be included in this type of research.
The aim of the present article is to introduce a model for the construction and evaluation of collaboration between researchers and external actors. The model is based on a review of established traditions and frameworks for such collaboration. It is summarized in the components purpose, actor, magnitude and process (PAMP, SAPO in Swedish) corresponding to the questions why, with whom, how much and when?
The model will enhance the possibility of researches and external actors to approach collaboration systematically and evaluate it critically. This will in turn increase the efficiency of collaborative efforts and usefulness of findings within the multifaceted research field of ageing studies.
Lungfunktion i hög ålder och dess samband med fysisk aktivitet från medelålder upp till hög ålder
Authors: Mehmedi Liberta , Nilsen Charlotta , Kåreholt Ingemar
Published: April 2021

Studien undersöker sambandet mellan lungfunktion i hög ålder och fysisk aktivitet från medel­ålder till hög ålder, samt sambandet mellan fysisk aktivitet i medelålder och i hög ålder. Vi använder data från Levnadsnivåundersökningen, LNU, och Undersökningen om äldre personers levnadsvillkor, SWEOLD. Deltagarna intervjuades i medelålder (genomsnitt 53 år), sen medelålder (genomsnitt 61 år) och hög ålder (genomsnitt 81 år), med en uppföljningstid på 24–30 år från medel­ålder till hög ålder.
Mer fysisk aktivitet i sen medelålder har ett samband med bättre lungfunktion i hög ålder. Sambandet består men blir mindre starkt när fysisk aktivitet i hög ålder inkluderas i analysmodellen. Det finns ett starkt samband mellan fysisk aktivitet i hög ålder och bättre lungfunktion i hög ålder. Fysisk aktivitet i sen medelålder har ett positivt samband med fysisk aktivitet i hög ålder.
Vår studie visar vikten av fysisk aktivitet även högt upp i åldrarna för att bibehålla god lungfunktion. Insatser som främjar fysisk aktivitet är av särskild vikt för att främja ett fortsatt hälsosamt åldrande, även för de allra äldsta.
 
Lung function in older age and physical activity from midlife to older age – A longitudinal study with 24-30 years of follow-up
The study investigated the role of physical activity, from midlife to older age, in lung function in older age. In order to increase the understanding of the relationship between physical activity and lung function, the relationship between physical activity in midlife and physical activity in older age was also studied.
Two Swedish studies based on nationally representative samples were used in this study, the Level of living survey, LNU, and the Swedish panel study of living conditions of the oldest old, SWEOLD. The participants were interviewed on three occasions; at the mean ages of 53 years, 61 years, and 81 years. The average follow-up time from the last to the first interview was 24-30 years. The results show that more physical activity in late midlife (mean age of 61 years) was associated with better lung function in older age. The association persists but attenuates when physical activity in older age was included in the analyses. There was also a strong association between physical activity in older age and better lung function in older age. Physical activity in late midlife had a positive association with physical activity in older age. This study shows the importance of physical activity in late midlife and in older ages to maintain good lung function in older ages. To invest in preventive actions in the form of physical activity are vital to be able to promote healthy aging, and should include the oldest old (76+).

Field experiments were carried out in 2018 and 2019 cropping seasons to determine the effect of fertilizer application on soil properties and yield of sesame varieties in Southern Guinea and Sudan Savanna Agro-ecological Zones of Nigeria. Treatments consisted of three varieties of sesame (Jigida, NCRIBEN-01M and NCRIBEN-032) and four levels of NPK 15:15:15 fertilizer (0, 50,100 and 150 kg ha-1). Treatments were laid out in a randomized complete block design (RCBD) and replicated thrice. Prior to planting, surface (0-15 cm) soil samples were collected from eight points and bulked; post-harvest composite soil samples were also collected on the basis of treatments. All soil samples were analyzed using standard analytical procedures. Data on yield parameters collected include number of capsules per plant, number of seeds per capsule, length of capsule (cm), 1000 capsule weight (g), 1000 seeds weight (g) and seed yield (t ha-1). The crop data generated from the study were subjected to Analysis of Variance (ANOVA) using Genstat Release 10.3 DE after which significant means were separated using Least Significant Difference (LSD) at 5 % level of probability. Results indicated that the soils of both locations were inherently poor in essential plant nutrients. The improved varieties (NCRIBEN-01M and NCRIBEN-032) performed better than the local variety in terms of yields in both cropping seasons. Sesame yield increased with increase in fertilizer application rates up to 150 kg ha-1. The effect of varieties on soil properties did not differ significantly however, the improved varieties left lower essential nutrients in soil when compared with the local variety. Fertilizer application at 150 kg ha-1 favoured the retention of organic matter as well as other essential nutrient elements in soil. Location effect showed that the Potiskum soil had more nutrients than that of Makurdi. For sustainable sesame production and maintenance of soil fertility in both locations, application of 150 kg ha-1 of NPK 15:15:15 to sesame fields is recommended.

Authors: Bastien Nathan , Kelly Sean , Lybeck Dustin
Published: April 2021

Complication rates associated with intercalary allograft reconstruction may be reduced by maximizing tenants of allograft reconstruction. Intercalary allograft reconstruction using a hemispherical reaming technique for graft-host interface may increase surface contact areas, provide intimate contact between surfaces, and equally distribute pressure subsequently decreasing risk of nonunion. The purpose of these case reports was to present short-term results for limb salvage using this novel technique for two young, active duty military members who returned to full-impact activity.
Selection of Potential Sites for Sustainable Development of Solar Photovoltaic Plants in Northeastern Brazil Using GIS and Multi-Criteria Analysis
Authors: Macedo Márcia , Macedo Marlos , Marinho Manoel , Rabbani Emilia Kohlman
Published: April 2021

Brazil has one of the highest percentages of solar radiation in the world and which it is a favorable condition to generate electricity using solar photovoltaic systems. The construction of photovoltaic plants depends on the site selection that influences the electricity generation capacity and the socio-economic benefits that can be derived from it in the future. This article proposes to combine Spatial analysis that involves the acquisition and management of spatial data using a Geographic Information System (GIS), and the fuzzy multi-criteria AHP-TOPSIS model to identify potential locations for the installation of solar photovoltaic systems in the northeastern region of Brazil, State of Pernambuco. The combination of GIS and fuzzy AHP-TOPSIS offers the user the possibility of assigning merit categories to the mapping according to multiple assessment criteria. The GIS include factors of the restrictions and criteria. The restrictions are inserted into the GIS using layers defined from current legislation (urban areas, undeveloped land, community sites, infrastructure, etc.), which reduce the study area by eliminating zones in which PV installation is not permitted. The results show that 22 and 40% of the area of the state of Pernambuco has the very high and high potential, respectively, for the implantation of PV.
Teletrabajo y call center. La experiencia mexicana durante la pandemia en 2020
Authors: Hualde Alfaro Alfredo , Micheli Jordy
Published: April 2021

A raíz de la pandemia del Covid-19 durante el año 2020, una gran mayoría de call centers en México trasladaron sus operaciones total o parcialmente a los domicilios de los operadores. Este fenómeno modificó la forma de operar de los call centers y dio lugar a experiencias inéditas tanto en las formas de organización del trabajo como en la propia experiencia de los operadores. En este artículo describimos algunos aspectos de dicha experiencia con base en lo observado en los call center de México por medio de entrevistas con operadores en la Ciudad de México y Tijuana. El fenómeno permite reflexionar acerca de los retos organizativos y normativos de llevar la operación de los call center al terreno del home office en una actividad eminentemente presencial que al mismo tiempo se está viendo afectada por los efectos de la automatización. En función de dicha experiencia, es pertinente preguntarse si la deslocalización observada en los call center será un fenómeno pasajero o los call center formarán parte de las actividades híbridas en las cuales se combine la presencia física en el centro de trabajo con la actividad virtual.

Suitable electro-catalytic technique is established for the selective determination of Indigo Carmine (IC) at poly(arginine) modified carbon paste electrode (PAMCPE). The surface morphological study of the electrode is done through Field Emission Scanning Electron Microscopy (FESEM). The different parameters such as concentration, pH and scan rate on the electrode response are studied. The individual and simultaneous performance of IC and Riboflavin (RF) is carried out through differential pulse voltammetry. The electrocatalytic response of the sensor varied with the concentration of IC in the range from 2×10-7 M to 1×10-6 M and 1.5×10-6 M to 3.5×10-6 M is observed. Limit of detection (LOD) and the limit of quantification (LOQ) is found 2.53×10-8 M and 8.43×10-8 M respectively. The developed PAMCPE successfully shows better electrochemical response towards IC when compared with BCPE. Preparation and characterization of both the electrodes is simple and easier. This has derived a standard method for the determination of IC in real samples.

Rasmussen’s Aneurysm: A Rare and Potentially Fatal Cause of Hemoptysis
Authors: Jaber Johnny , Innabi Ayoub , Patel Divya
Published: April 2021

Rasmussen’s aneurysm is a rare and fatal cause of hemoptysis secondary to infection with pulmonary tuberculosis. The most commonly involved vessels include the bronchial arteries, but rarely can involve the pulmonary artery. We report the case of a 62-year-old female from the Philippines with undiagnosed pulmonary tuberculosis who presented with massive hemoptysis. After hemodynamic stabilization, Rasmussen’s aneurysm was diagnosed by computed tomography of the chest with angiography, confirmed with invasive angiography. She was treated definitively with glue embolization of the affected artery.

Directions of theoretical and research changes in Polish early school pedagogy - from mono to polydiscoursiveness
Authors: Bałachowicz Józefa , Zbróg Zuzanna
Published: April 2021

The article presents the specificity of early school pedagogy as one of the sub-fields of pedagogy with its decades-long heritage experience. Particular attention was given to the major directions of changes in the perception of a child as the empirical subject and a childhood being constructed in the educational institution, in the meaning of school. The most important problem areas of early school pedagogy were characterized, including those referring to reconstruction of early education culture, contemporary discourses of child/pupil education and preparation of early school teachers for working professional life, both in traditional and alternative models of education. Significant theoretical and empirical trends in study of children and early school teachers (1-3 class of primary school) were determined, supported by the illustration of the list of selected monographs published from 2000-2020. The article highlights, the multiplicity of discourses and diversity of approaches to child education typical for contemporary early school pedagogy, which is considered to be the positive indicator of development in the discussed sub-field.
Interferon-λ3 Gene Polymorphic Variants, rs4803217 and rs12980275, Responsiveness to HBV Vaccine and Outcome of HBV and HCV Exposure in Hemodialyzed Patients

Published: April 2021

Background: In non-uremic populations, rs4803217 in the IFNL3 messenger RNA 3’ untranslated region or rs12980275 downstream of IFNL3 is connected with the spontaneous or therapeutic clearance of HCV and HBV, and rs12980275 is correlated with plasma IFN-λ3 levels. Moreover, rs12980275 is associated with the sustained virological response following antiviral therapy of chronic hepatitis C in hemodialysis patients. Objectives: We investigated IFNL3 polymorphisms, rs4803217 and rs12980275, for association with responsiveness to HBV vaccine and natural consequences of HBV and HCV exposure among hemodialyzed individuals. Methods: The capacity to produce protective anti-HBs titers was recognized if they were ≥ 10 IU/L after vaccination or natural exposure. The IFNL3 rs4803217 (G>T) and rs12980275 (A>G) genetic variants were analyzed using a high-resolution melting curve method in 1,337 hemodialysis subjects. Plasma IFN-λ3 was determined in 188 individuals using ELISA. The Kaplan-Meier method was applied for the analysis of survival probability. Results: The tested polymorphisms did not show associations with the capacity to generate protective anti-HBs titers after HBV vaccination or exposition and self-limitation of HBV exposure. Natural HCV clearance was connected with the IFNL3 rs4803217 GG genotype (OR: 3.036, 95% CI: 1.544 - 5.969, P = 0.001) and haplotypes comprising at least two more frequent alleles but without any variant allele of IFNL3/IFNL4 genetic variants (P < 0.05). Plasma IFN-λ3 levels were not directly influenced by IFNL3 rs4803217 and rs12980275, but differed concerning HBV/HCV serum markers (P = 0.00005) and firmly correlated with anti-HBs titers (r = 0.537, P = 4.15E-16). Both tested polymorphisms were not significantly associated with the survival of hemodialysis patients. Conclusions: Genotyping IFNL3 rs4803217 may be advantageous in the prognosis of natural HCV clearance but does not predict the self-limitation of HBV exposure, responsiveness to HBV vaccine, or hemodialysis patients’ mortality.
