Desafíos del uso de TikTok como plataforma educativa: Una red multitemática donde el humor supera al debate
Authors: Tejedor Calvo Santiago , Cervi Laura , Robledo-Dioses Kelly , Pulido Rodríguez Cristina
Published: June 2022

TikTok es actualmente la aplicación más descargada después de WhatsApp y Messenger. En el ámbito educativo la red social marcó un precedente en España, cuando el 2020 desarrolló el proyecto #Edutok. Analizamos el contenido de 800 vídeos de las cuentas de los tiktokers españoles consideradas parte de #Edutok, con el objetivo de estudiar perfiles, tipología de contenidos educativos, temáticas predominantes, emociones involucradas, tipo de interacciones, y uso de recursos, entre otros. Se encontró que la explotación educativa de TikTok atraviesa una etapa muy incipiente, aspecto que enlaza con la juventud de la red social. Destaca su idiosincrasia multitemática y la ausencia de lineamientos educativos, que desemboca en vídeos donde prima el contenido de humor en detrimento de la invitación al debate, y que desaprovechan recursos propios de la narrativa audiovisual, como extractos de documentales o películas. Entendemos que el aprovechamiento de TikTok como herramienta educativa demandará de investigaciones teórico-prácticas que, por un lado, contemplen su particular idiosincrasia y, por otro, apliquen, en este nuevo escenario, aprendizajes derivados del trabajo educativo multimedial, colaborativo y bidireccional de otras plataformas.
Educación patrimonial y ecofeminismo. Análisis de los ecomuseos españoles.
Authors: Lucas Palacios Laura , Arroyo Mora Elisa , Trabajo Rite Mónica
Published: June 2022

Las prácticas del ecofeminismo crítico son aún desconocidas en la educación a pesar de las potencialidades que nos ofrece para la formación de una ciudadanía crítica y democrática. Por esto, el presente trabajo se propone un doble objetivo: por un lado, establecer pautas para el desarrollo de propuestas de educación patrimonial desde la perspectiva ecofeminista, y, por otro, analizar los enfoques conceptual y metodológico y la finalidad de 55 ecomuseos españoles con el fin de averiguar si sus propuestas didácticas se ajustan a los valores y principios del ecofeminismo crítico. Para indagar sobre dichas propuestas, se ha hecho un análisis cualitativo de las páginas web de los ecomuseos utilizando como instrumento un complejo sistema de categorías con subcategorías, indicadores y descriptores que nos permite clasificar los datos obtenidos en una hipótesis de progresión desde una perspectiva simple de la educación ambiental hasta la educación ecofeminista deseable. Como primeros resultados, hemos encontrado que los ecomuseos españoles no contemplan en su mayoría la perspectiva de género y que ni siquiera tienden a ahondar en los problemas ecosociales con el objetivo de promover una transformación social en el territorio del que forman parte.

La formación universitaria no debe limitarse a una mera instrucción de habilidades profesionales, sino que debe fomentar el desarrollo integral del alumnado. Este planteamiento se hace especialmente necesario en la formación de maestros y maestras, subrayando la necesidad de implementar estrategias metodológicas que lo posibiliten. A través de una aproximación metodológica mixta, se han analizado los efectos producidos por el Aprendizaje-Servicio sobre las habilidades y actitudes cívicas del alumnado (n=117). Los resultados cuantitativos muestran una mejora estadísticamente significativa en el cuestionario en global. Además, la parte cualitativa permite profundizar sobre los aprendizajes relacionados con las dimensiones que presentan mejoras estadísticamente significativas. Los resultados obtenidos sugieren que el Aprendizaje-Servicio se erige como una estrategia idónea para fomentar el desarrollo de las habilidades y actitudes cívicas del futuro profesorado.
inclusión educativa durante la escuela Post-COVID desde la mirada del profesorado de Pedagogía Terapéutica.
Authors: Gonzalez Blas , Moreno Parra Jesús , Mañas Olmo Moisés
Published: June 2022

La escuela post COVID ha venido acompañada de una serie de medidas higiénico-sanitarias y organizativas que han limitado las prácticas inclusivas que se venían realizando en los centros educativos. El propósito de esta investigación es conocer y analizar las experiencias escolares, en términos de inclusión, del alumnado con necesidades específicas de apoyo educativo (NEAE) durante el curso 2020/21, desde las voces del profesorado implicado. Metodológicamente, planteamos una investigación cualitativa en la que se han realizado entrevistas semiestructuradas virtuales y grupos focales en los que han participado 37 maestros y maestras de Pedagogía Terapéutica de la comunidad autónoma de Andalucía. Del intercambio final emergen situaciones de exclusión escolar, como consecuencia, por un lado, de las separaciones espaciales dentro de los centros escolares (grupos burbuja), y, por otro lado, debidas a la falta de recursos destinados a la atención del alumnado escolarizado en Aulas Ordinarias y Aulas de Educación Especial que han limitado sus experiencias sociales, emocionales y de aprendizaje; situaciones estas que muestran que hablar de diversidad en la escuela, antes y ahora, sigue siendo sinónimo de exclusión.
Isolating and Tracking Noise Sources across an Active Longwall Mine Using Seismic Interferometry

Published: June 2022

The ability to monitor seismicity and structural integrity of a mine using seismic noise can have great implication for detecting and managing ground-control hazards. The noise wavefield, however, is complicated by induced seismicity and heavy machinery associated with mining operations. In this study, we investigate the nature of time-dependent noise cross-correlations functions (CCFs) across an active underground longwall coal mine. We analyze one month of continuous data recorded by a surface 17 geophone array with an average station spacing of ∼200 m. To extract coherent seismic signals, we calculate CCFs between all stations for each 5-min window. Close inspection of all 5-min CCFs reveals waveforms that can be categorically separated into two groups, one with strong and coherent 1–5 Hz signals and one without. Using a reference station pair, we statistically isolate time windows within each group based on the correlation coefficient between each 5-min CCF and the monthly stacked CCF. The daily stacked CCFs associated with a high correlation coefficient show a clear temporal variation that is consistent with the progression of mining activity. In contrast, the daily stacked CCFs associated with a low correlation coefficient remain stationary throughout the recording period in line with the expected persistent background noise. To further understand the nature of the high correlation coefficient CCFs, we perform 2D and 3D back projection to determine and track the dominant noise source location. Excellent agreement is observed on both short (5-min) and long (daily) time scales between the CCF determined source locations, the overall migration of the active mining operation, and cataloged seismic event locations. The workflow presented in this study demonstrates an effective way to identify and track mining induced signals, in which CCFs associated with background noise can be isolated and used for further temporal structural integrity investigation.

Authors: ÇAKMAK Selma
Published: June 2022

Dilin kesinliği meselesi İslamî ilimlerin birçok alanında farklı şekillerde ortaya çıkan metodolojik yönelimi temsil eden bir konudur. Konunun müstakil olarak İslamî ilimler literatüründe bir problem olarak tartışılması Fahreddin er-Râzî’nin “lafzî deliller kesinlik taşımaz” iddiası ile başlamıştır. Bu iddia şer‘î ilimlerin meşruiyetini sarsması, vahyin güvenirliğini ve anlaşılabilirliğini tartışmaya açma ihtimali sebebiyle birçok İslam âlimi tarafından eleştirilmiştir. Şüphesiz ki bu iddiaya en sert tepki metodolojilerini naklî delillerin temeli üzerine inşa eden ilim çevrelerinden gelmiştir. Bu âlimlerin sembol ismi de kendine özgü metodolojik yaklaşımı ve açıklamalarıyla ön plana çıkan Takiyyüddîn İbn Teymiyye’dir. Bu çalışmada mantık ilmine ve kelâm âlimlerine karşı çıkışlarıyla bilinen İbn Teymiyye’nin dilin kesinlik taşımadığı iddiasına karşı müdafaası ve “sarih nakille sahih akıl çelişmez” prensibi çerçevesinde geliştirdiği argümanları konu edinmiştir. Bu çerçevede özgün yaklaşımları ile nakli İslâmî ilimlerin temeline yerleştiren İbn Teymiyye’nin esas aldığı ilkelerin bu iddiaya karşı geliştirdiği söylemlerle uyumlu olduğu, müdafaasını güçlü ve tutarlı bir düşünce zeminine yerleştirdiği görülmektedir.

INVESTIGATION OF MICROALGAE GASIFICATION UNDER STEAM ATMOSPHERE IN DOWNDRAFT GASIFIER BY USING ASPEN PLUS®
Authors: KEKİK Berna , ÖZVEREN Uğur
Published: June 2022

Energy production is facing the environmental and economic issues due to growing population and uncertainties about the fossil fuels. These concerns prompt the researchers to find widely available and renewable alternative such as biomass instead of the fossil fuels. Microalgae is one of the promising biofuels owing to its rapid growth speed and higher calorific value. Steam gasification is an alternative way converting biomass to syngas with higher H2 and lower CO2 content compared with the other thermochemical conversion processes. In the present work, the downdraft gasifier model was developed by using Aspen Plus® program that has the capability to investigate the performance of microalgae gasification. Before the performance evaluation of the gasification, validation of the model successfully completed and exit gas compositions of H2, CO2, CO and CH4 were found very close for experimental study and the developed model. Effects of the main parameters of the process such as steam/biomass ratio and gasification temperature were assessed on the syngas composition and higher heating value (HHV) of syngas. The obtained results were stated that the increment in the temperature showed great effect on the H2 and CO compositions of syngas, they increased from 50.72% to 56.47% and 28.11% to 28.84% respectively. The simulation results also illustrated that the rising of the S/B ratio was favored the steam related reactions and increased the H2 content in syngas. However decreasing trend of the CH4 caused reducing of the HHV of syngas as a function of temperature and steam as well.

This study aims to analyze the effects of the time windows choices in Vehicle Allocation Problems with respect to economic, social, and environmental indicators. As far as we know, such an attempt does not exist in the related literature. For this purpose, we first present a Mixed Integer Programming model for a generic Vehicle Allocation Problem with profit maximization objective under time windows constraints. This model is used to conduct analyses for demonstrating the applicability of the model in practice and to reveal potential effects of the time windows choices on economic, social, and environmental outcomes of allocation decisions in Vehicle Allocation Problems. The numerical results show that loosened time windows have the potential to provide economic and environmental benefits in the addressed problem. We also propose a collaboration policy attractive to both the transportation company and its customers through price discounts, which improves economic and social performances of the addressed transportation logistics network.

Published: June 2022

El presente trabajo aborda la estimación de la diversidad funcional (FD) del estrato herbáceo en un ecosistema de dehesa mediante datos hiperespectrales obtenidos con un espectro-radiómetro portátil ASD FieldSpec® 3 (Analytical Spectral Devices Inc., Boulder, CO, EE. UU.). Los datos ópticos se correlacionaron con variables biofísicas (área foliar específica (SLA), biomasa aérea (AGB), índice de área foliar (LAI) y contenido de nitrógeno (N%)) e índices de diversidad tradicionales como Shannon y Evenness y otros relacionados con la diversidad funcional como el índice multidimensional de dispersión funcional (FDis) usando como variables predictoras: a) índices de vegetación (VIs) y métodos de regresión simple, y b) bandas espectrales y Partial Least Squares Regression (PLSR). Las correlaciones, especialmente de las variables biofísicas relacionadas con FDis, mejoraron sustancialmente al utilizar información hiperespectral (R2 >0.6, rRMSE <0.1) lo que confirma el interés de la dimensión espectral para estimar la diversidad funcional de un ecosistema complejo como es el caso de los pastizales semi-áridos.

Published: June 2022

The identification of a bride range of organic pollutants in real water samples, especially in brackish water or wastewater is still a major issue in chemical analysis. The paper presents a comparison of different solid phase extraction SPE methods for the preparation of brackish water samples before the chromatographic analysis. The SPE methods were dedicated to the extraction of selected organic cosmetic ingredients - butylated hydroxytoluene BHT, oxybenzone BP3, and octyl methoxycinnamate OMC. Six types of SPE cartridges with different bed types and weights were tested. The SPE methods included the conditioning of the column bed with organic solvents, loading of the pre-treated brackish water samples, washing out the impurities, and the elution of the analytes. The highest recovery of the tested cosmetic ingredients, which has reached the value of 100% for BP3 and OMC, and exceeded 99% for BHT, was noted for the cartridge with the C18 (octadecyl) bed.

The use of synthetic pesticides has been widely practiced by farmers to control plant diseases. However, it can promote negative impacts such as environmental pollution, threatening human health, and making pathogens more resistant. This study aims to determine the inhibition of Trichoderma Tc-Jjr-02 in vitro against Colletotrichum sp. and test its ability as a biopesticide and biofertilizer agent in suppressing the growth of anthracnose disease and chili production. The results show that, there was no interaction effect between the application of Trichoderma Tc-Jjr-02 as a biopesticide and biofertilizer agent. The in vitro test reveals that Trichoderma Tc-Jjr-02 could inhibit the growth of pathogenic colonies up to 61.4% at 11 days after inoculation. In vivo test show, that application of Trichoderma 6 hours before inoculation of pathogens (T1) and Trichoderma inoculation concurrent pathogens (T3) can reduce the symptoms intensity of anthracnose attacks 70% and 43%, respectively, then increasing the number of fresh fruit 62.66% and 76.58%, respectively, also increasing fresh fruit weights 84.83% and 91.90% respectively, compared with the pathogen inoculation treatment six hours before the application of Trichoderma. Thus, Trichoderma is more effective when applied before inoculation of pathogens and more suitable as a prevention agent. Using Trichoderma asperellum as biopesticed can protect the environment.

Published: June 2022

In recent years, virtual reality labs have been widely used in teaching. Virtual reality labs built by virtual reality technology have been applied in different disciplines. Many studies have also shown that virtual reality experiments can replace real experiments, and some even have better learning effects than real experiments. For current digital camera experiment courses in China, it is necessary to use virtual reality labs. Attention guidance is added to the design of experimental courses. However, questions arise about learners’ acceptance and experience of digital camera virtual reality labs. Another potential problem is learners’ acceptance and experience of labs after attentional guidance is added. Therefore, the purpose of this research is to design and develop a digital camera virtual reality lab and study various aspects of the user experience (UX). The User Experience Questionnaire (UEQ) was used to obtain students' responses after completing digital camera virtual reality experimental courses. The subjects were 30 college students (N = 30). Participants were divided into two groups. In the first group, 15 students participate in the test of the virtual reality lab with attention guidance, and in the other group, 15 students participate in the test of the virtual reality lab without attention guidance. From the results, it is concluded that the UX level of the digital camera virtual reality lab is promising and positive. The subjects were satisfied with the virtual reality lab with attention guidance and without attention guidance, though the subjects with attention guidance were more satisfied.

Authors:   the Multimedia University, Malaysia, Hui Wong Guo , Neo H.-F. , Teo C.-C.
Published: June 2022

Augmented reality (AR) empowers virtual and interactive experience through smartphone devices. Nowadays, technologies have become more advanced, and AR is generally compatible with smartphones, thus being more accessible globally. Furthermore, many developers have started to create AR-based applications in fields such as edutainment, games, furniture, biomedicine, geology, and entertainment. AR-based edutainment applications allow students to observe experiments in a safe environment and improve understanding through manipulation and multi-angle observation of virtual three-dimensional (3D) objects. In addition, AR has become increasingly cost-friendly, accessible, and effective. This paper thus aimed to design and create a novel edutainment learning application based on AR targeted at children. This is because AR enhances the learning content so as to be more interactive and exciting as it is projected in a 3D realm. The powerful visual models enable users to have a better understanding to learn a specific theory through visualizations. This research used experimental analysis consisting of a pre-and post-test survey. The pre-test results demonstrated that some respondents were not aware of AR technology and were not supportive of it. In contrast, the post-test result has revealed that the respondents felt that the proposed application is easy to use, user friendly and the learning content is interactive.

Published: June 2022

Background: Metallo-β-lactamases (MBL) have a wide spectrum of activity and they confer a higher level of resistance to all β-lactams antibiotics including Carbapenem. The active site in MBLs contains either 1 or 2 Zn2+ ions for their catalytic mechanism. All MBLs share a common feature of being inhibited by EDTA. Metallo-β-lactamase-producing gram-negative bacteria are the most important nosocomial pathogens. The present study was conducted to detect Metallo-β-lactamase (MBL) production in gram-negative bacilli by Combined Disc Synergy Test (CDST) and Double Disc Synergy Test (DDST) with 0.1M EDTA as a chelator and to see their antibiotic susceptibility pattern of them.Methods: The cross-sectional observational study was carried out in the Department of Microbiology, Chittagong Medical College, during the period of July 2015 to June 2016. Samples were collected from patients admitted to CMCH. Standard Microbiological procedures and biochemical tests were carried out for the isolation and identification of MBL. SPSS software is used for data analysis.Results: When 66 screening positive MBL isolates were subjected to the phenotypic confirmatory test CDST detected 50 (25.4%) and DDST detected 48 (24.4%) as MBL producers. Among these isolates, we found Acinetobacter spp. 7 (100%), as the leading MBL producer followed by Pseudomonas spp. 16 (32.6%), E. coli 10 (20%) and Klebsiella spp. 15 (17.4%).Conclusions: In a laboratory where multiplex PCR molecular set-up is not available CDST and DDST are convenient phenotypic methods and can be implemented in routine microbiological laboratories as well as in primary health care setup for daily application to monitor the production of MBLs.

Published: June 2022

Background: Skilled care during delivery is critical in preventing maternal deaths. Although India has taken many steps to alleviate the financial burden of institutional delivery, women of low socioeconomic status in marginalized, rural communities still have a higher rate of home deliveries than national average. This paper examines characteristics of women who deliver at home in tribal communities in Mysore, Karnataka State, India.Methods: The 69 women who had given birth at home between June 2013 and June 2017 were interviewed about their choice to deliver at home. Demographic data was compared to data obtained from all women who delivered in tribal communities in the same area and in the same time frame.Results: The findings from this study indicate that women who deliver at home have higher gravidity, have a greater number of living children and are older than the average. Additionally, most home deliveries occur in June and occur in the night time. Lastly, most women reported that their husbands decided on their delivery site.Conclusions: Data analysis and interviews reveal that increasing the number of institutional deliveries is a multifaceted issue that must take into account the demographic, economic and cultural factors behind the decision.

Las reservas de petróleo hoy en día se encuentran integradas en gran medida por aceites pesados y extrapesados, de los cuales se obtienen pequeñas cantidades en su producción primaria. En este tipo de yacimientos la aplicación de métodos de recuperación térmica es una etapa importante en el programa de desarrollo y explotación de los campos. La inyección de vapor es uno de estos métodos empleados con el objetivo principal de reducir la viscosidad del crudo. En la literatura existen investigaciones experimentales las cuales recopilan evidencia de una interacción entre el vapor y el aceite en el yacimiento, permitiendo la aparición de reacciones químicas en un proceso denominado acuatermólisis, esta transformación es un resultado químico que se presenta a temperaturas entre los 200 y 325 °C típicas de la inyección de vapor. La adición del catalizador al proceso posibilita establecer un escenario donde se reduce la energía de activación necesaria generando cambios permanentes en propiedades del crudo, incluso si el calor suministrado se ha dispersado. La representación de este fenómeno mediante simulación numérica de yacimientos constituye un desafío, ya que las reacciones que gobiernan el proceso de cambios fisicoquímicos sobre el crudo presentan incidencias por parte de factores externos los cuales no pueden ser representados de manera directa por los simuladores comerciales. De esta manera, el presente trabajo se enfocó en el análisis de las investigaciones encontradas en la literatura acerca de la representación de los fenómenos fisicoquímicos, con los cuales se generó una metodología para replicar los efectos mediante simulación numérica.

Published: June 2022

Staphylococcus aureus meticilino resistente es un microorganismo aislado, principalmente a nivel hospitalario; sin embargo, esta condición ha cambiado en los últimos años, pues hoy en día se reconoce como el agente causal de infecciones adquiridas en la comunidad por niños sin factores predisponentes asociados. Esto puede variar en todo el mundo, pero hay una alerta global por el aumento del problema. En América Latina, esto ya ha sido reportado en países como Argentina y Colombia. Evaluar los gérmenes circulantes a nivel regional y sus características genotípicas es importante para el manejo clínico de algunos pacientes, incluso niños menores de un año, quienes también son susceptibles a este tipo de infección. En este reporte, se presentan dos casos en niños menores de un año, incluyendo un recién nacido, lo que hace de este un grupo etario susceptible. La sospecha clínica de esta bacteria de adquisición en la comunidad ayuda a la elección adecuada del esquema antibiótico, con mejores resultados clínicos. Por lo tanto, debe ser una prioridad realizar la vigilancia local de las infecciones por Staphylococcus aureus adquiridas en la comunidad y determinar los protocolos de manejo, según los grupos de edad y condiciones asociadas.

Authors: Gruchoła Małgorzata
Published: June 2022

W momencie kryzysu, którego przyczyną może być katastrofa naturalna (np. pandemia COVID-19), każda grupa społeczna szuka kozła ofiarnego (teoria René Girarda). Mechanizm ten w artykule obrazuje liczba zgonów z powodu SARS-CoV-2 traktowanych jako ofiara kolektywna. Celem artykułu było zbadanie źródeł i form przemocy oraz zidentyfikowanie kozła ofiarnego w postrzeganiu pandemii COVID-19 na podstawie 24. raportów Eurobarometru: Public opinion monitoring in the time of COVID-19, obejmujących okres od marca 2020 roku do czerwca 2021 roku. Opinie respondentów w zakresie konsekwencji pandemii traktowanych jako przejaw przemocy zostały zanalizowane w trzech obszarach: ekonomicznym, społecznym i zdrowotnym. Zastosowano ilościową analizę zawartości raportów, jakościową analizę treści, metodę porównawczą oraz analityczno-opisową.

Przyjęto sześć szczegółowych hipotez badawczych, z których trzy zostały potwierdzone. Została także tylko dla pierwszej fali potwierdzona hipoteza główna zakładająca, iż liczba zgonów w poszczególnych państwach UE, odnotowana w kolejnych falach pandemii COVID-19, traktowanych jako ofiara kolektywna, jest proporcjonalna do łącznej liczby odnotowanych przypadków przemocy ekonomicznej, społecznej i zdrowotnej w danym państwie. Wzrost zgonów implikuje wzrost zidentyfikowanych działań przemocowych.
An Investigation on the Flexural and Thermo-mechanical Properties of CaCO3/Epoxy Composites
Authors: BAŞTÜRK Bahar
Published: June 2022

Present work focused on the flexural and thermo-mechanical characteristics of epoxy based composites filled with 3 different calcium carbonate (CaCO3) concentrations: 1.5, 3 and 5 wt.%. Composite specimens were fabricated through conventional casting method and subjected to flexural test via 3 point bending fixture. Additionally, dynamic-mechanical analyzer (DMA) with single cantilever mode was used to reval the thermo-mechanical responses of samples. The findings showed that the filler concentration increase led to the increase of storage modulus (E') for all specimens while the glass transition temperature (Tg) slightly decreased for 1.5 wt. % CaCO3 filled epoxy composite. The 5 wt.% CaCO3 loaded composite showed maximum E' and Tg values with 10% and 1.5% improvement, respectively. Based on flexural test results it was surprisingly found that, 1.5% wt. CaCO3 addition attained the highest strength with almost 27% improvement among all samples. However, 5 wt.% CaCO3 introduced composites displayed the lowest mechanical performance due to the presence of agglomerates/tactoids, which was verified from SEM images as well.

In this study, 4 Salvia species found in the Aethiopis section distributed in the province of Mardin in the Southeast of Turkey between the years 2018-2021 were analyzed comparatively in terms of anatomy. Transverse sections taken from the roots, stems, leaves, and petioles of the taxa were examined under a light microscope. S. brachyantha ssp. brachyantha, S. montbretii, S. palaestina, and S. syriaca taxa were analyzed anatomically. S. montbretii and S. syriaca species were analyzed in detail for the first time anatomically. In the anatomical examinations, it was observed that the root, stem, leaf, and petiole structures of the taxa were similar, but the shapes and sizes, in addition to the tissue layer and pith row numbers, were different. As a result, anatomical characters provide important information in the differentiation of species.

Published: June 2022

For creating complex geometric shapes in the cast part, salt was used to produce core instead of sand which is thermo-chemical or chemical process using resin as a binder.In salt core casting, the efficiency will be increased by reducing the core gas-induced errors in the part. The harmful effect on the environment will be reduced with the absence of odor and smoke from the core gas.Using water in salt core breaking instead of mechanical impact and vibration during sand core breaking will bring benefits such as eliminating the noise source and using less energy. By eliminating the dust generated during sand core breaking, its harmful effects on the environment will be reduced. Since the salt core can be dissolved in water and removed from the piece without any residue, there will be no problem of sand remaining in the sand core from time to time.

With the increasing demand for energy globally and the need to reduce fossil fuels, paying attention to renewable and clean energy sources is necessary. Solar systems are viable among renewable energy sources for heat and electricity generation. In this study, an Off-grid solar system was investigated by considering the effect of climate conditions and environmental factors such as dust on the performance of PV panels. Performance and efficiency of PV system using PVsyst software in four cities of Iran (Mashhad, Abadan, Rasht, and Sanandaj) with different climates were presented. This study shows that most of the loss occurs in Sanandaj, with the cold and humid climate, which results show an 11.19% efficiency reduction. On the other hand, with its hot and humid climate, Abadan has an 8.33% loss due to the geographical location of this city in the vicinity of desert areas. With a temperate and humid climate, Rasht has a 2.27% decrease, and Mashhad, with a cold and dry climate, has a 2.19% decrease in yield.

Background: Ankle ligament injuries in the sports like basketball, volleyball, and cricket are the most common reasons for missed participation in athletics, accounting for 14% of all sports injuries. These injuries may often require splinting and rest for a longer duration, leading to a permanently reduced level of sports performance. The autologous conditioned cytokine-rich serum (ACRS) is becoming a reliable treatment option in acute ankle injuries as it enhances biological healing. The objective of this study is to evaluate the role of ACRS in acute ankle injuries and report the efficacy of ACRS injections on time to return to physical activities.
Methods: 42 patients with clinical and radiological signs of ankle ligamentous injuries (grades 1 and 2) secondary to sporting or gaming activity were recruited for this study. Each patient received one injection of ACRS at the injury site and was put on a soft cast for one week. Clinical and functional evaluation was performed using the Visual Analogue Scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale, and the Foot and Ankle Disability Index (FADI) scores before the injection, at one week, i.e., after removing the soft cast, three weeks, six weeks, and three months.
Results: Our study showed gradual improvement of all the evaluation scales at all the follow-ups. Few patients showed minor side effects like aseptic effusion. The least common complaint was a pain in the subsequent days after the injection.
Conclusion: Our results, in conjunction with pre-existing studies in the literature regarding the biological effects of ACRS, demonstrate the viability of this therapy for the treatment of acute ankle injuries, showing the positive influence on pain and healing capacity and returning to gaming activities immediately in about two weeks without significant adverse effects.

Published: June 2022

Background: Neurilemmomas also called schwannomas are benign tumors originating from the Schwann cells participating in the peripheral nerve sheath and the pathophysiology of the formation of these tumors is not completely understood. Schwannomas are mostly benign with equal incidence rate in men and women. These tumors have been mainly found in the head and neck, upper extremities, and the trunk. Lower extremity schwannomas are extremely rare, specifically in the dorsum of the foot.
Case Report: In this report, we present an 18-year-old man referred to surgery clinic with a painful mass on the anterolateral dorsal aspect of his left ankle with radicular pain and paresthesia to the distal dorsum of the forefoot. After completing all the assessments including ultrasonography and magnetic resonance imaging (MRI), he underwent the surgical resection procedure. The pathology laboratory reported an encapsulated 35 * 20 * 15 mm solitary benign schwannoma.
Conclusion: The dorsal aspect of the foot is an extremely rare site for schwannoma formation, but practitioners should always be aware of rare underlying diseases for neurologic deficits or just a simple pain in the lower extremities.
‘Jannat Guest House': A challenge to the ‘Stereotype’ and celebration of ‘Impurities’: A Postmodern perspective to The Ministry of Utmost Happiness
Authors: Swarnakar Neha
Published: June 2022

Purpose of the study: The purpose of the study is to deconstruct the essentialist hegemonic discourse of purity and present ‘Jannat Guest House’ as a challenge to the ‘stereotype’ and a celebration of ‘impurities’ in The Ministry of Utmost Happiness by Arundhati Roy. Methodology: A postmodern perspective has been applied to this study. Postmodern theories of ‘plurality’, ‘shifts’ and ‘inclusion’ have been used for the meticulous study of the text. It uses the concept of ‘deterritorialization’ and the concept of ‘rhizome’ developed by Deleuze and Guattari. Main Findings: Arundhati Roy’s The Ministry of Utmost Happiness unpacks a narrative that, “by slowly becoming everything” resists the discourse of ‘purity’ as she has placed different voices irrespective of race, class, gender, or other binary specified terms, into one, Jannat Guest House. This study finds ‘Jannat Guest House’ as a Postmodern site of the dismantling of oppositional ‘binaries’ and a site of ‘inclusion’ which poses a threat to the ‘stereotype’ and a celebration of ‘impurities’. Applications of the study: The study is useful in the reading of the celebration of contaminated diversity. It will explore one of the mottos of the postmodern perspective and will be helpful to deconstruct the notions of purity. Novelty/Originality of the study: It will help to make the reader reciprocate the notions of impurities. It will help to dismantle the gleaming, consistent and coherent notions of purity. It will bring a change in their thinking over the concept of home, and celebration of individuality.
A Review on Quantitative Structure-Activity and Relationships (QSAR) Methods
Authors: Ram Sirvi Sakha
Published: June 2022

QSAR is an analytical application that can be used to interpret the quantitative relationship between the biological activities of a particular molecule and its structure. The product of QSAR will then produce useful equations, images or models in either 2D or 3D form that would relate their biological responses or physical properties to their molecular structure. Hologram QSAR (HQSAR) uses molecular holograms and PLS to generate fragment-based structure-activity relationships. Unlike other 3D-QSAR methods, HQSAR does not require alignment of molecules, allowing automated analysis of very large data sets. CoMFA can be applied, as it often is, when the 3D structure of the receptor is unknown. To apply CoMFA, all that is needed are the activities and the 3D structures of the molecules. Comparative Molecular Similarity Indices Analysis (CoMSIA) is known as one of the newer 3D QSAR methodology. This technique is most commonly used in drug discovery to find the common features that are important in binding to the relevant biological receptor. The partial least squares (PLS) method was used to explore a linear correlation between the CoMFA and CoMSIA fields and the biological activity values.
