Published: June 2024

This research aims to complement existing research regarding the leadership of Khulafaur Rasyidin in Islamic civilization which is described comprehensively and explained partially. This research is descriptive qualitative research with a literature study approach that refers to several sources of research data and data collection techniques in the form of a study of Islamic civilization during the time of Khulafaur Rasyidin. Data collection was carried out by searching and reconstructing from various sources such as articles in journals, books, and previous research that were relevant to the research study, which were then analyzed in a primordial manner. The focus of the research that will be addressed is Khulafaur Rasyidin's leadership in Islamic civilization. The data collection technique used in this research is the library research method, namely library research with the data analysis technique used in this research is the hermeneutic method. In this research, it can be concluded that during the time of the Rasyidin khulafaur, namely Abu Bakar Ash-Shiddiq, Umar Bin Khattab, and Ali bin Abi Talib, they had differentiated characteristics regarding their leadership during the Islamic civilization period where Abu Bakar implemented a model of government that had the characteristics of a monarchy, similar to a kingdom system, with himself as Caliph or head of government. Umar had an administrative system which was mostly an economic system and judicial organization. Then Usman was the first to form a navy which succeeded in expanding Islamic power to various regions. Meanwhile, Caliph Ali took a political policy that was said to be quite risky, because this policy caused hatred from high-ranking officials during Usman's caliphate.
AVERROEISME: AJARAN IBNU RUSYD YANG DIPAHAMI DUNIA BARAT DAN PENGARUHNYA TERHADAP RENAISSANCE
Authors: Kosasih Ade , Muhammad Fahmi Rezza Fauzi
Published: June 2024

The discourse on the role and contribution of Muslim scholars to the progress of mankind and modern life needs great attention. Their traces cannot be erased either from the existing facts or the collective memory of mankind. Ibn Rushd is one of the Muslim scholars who has made his mark on the Western World. Ibn Rushd is known in the Western world as Averroes. It is an indisputable fact that the traces of Ibn Rushd's scholarship are very clear in the Western world. This research explores the teachings and thoughts of Ibn Rushd who were influential in the Western World. The result of Ibn Rushd's thought has a very strong network to this day. The various rationality movements that took place in the West were inspired by the thought of Ibn Rushd. Therefore, the expression of Ibn Rushd's thought is something that really needs to be revealed, both its origin and its substance. The revelation of the origins and substance of this thought will prove the extent to which Muslim scholars contributed to modern civilization. Ibn Rushd's thought related to the relationship between philosophy and religion, namely that between philosophy and religion are interrelated. Philosophy reveals the nature of truth based on ratios; while Islam expresses a truth based on revelation from God. Islamic philosophy and religion should not contradict, so that the two cannot be separated and should even strengthen each other. Ibn Rushd's thought is understood and implemented by the West very differently, that is, only philosophical thought is considered correct.

Los salvadoreños ante la elección presidencial de 1989
Authors: IUDOP
Published: June 2024

Entre el 29 de octubre y el 15 de noviembre de 1988, se realizó una encuesta de opinión pública con una muestra representativa de la población adulta urbana y rural de ocho departamentos de El Salvador (N=1004 personas). El 85.7 por ciento, es decir más de ocho de cada diez salvadoreños, expresan su intención de ir a votar en las próximas elecciones presidenciales. Sin embargo, apenas 16.1 por ciento se mostraban seguros de que en dichas elecciones no habría fraude; 47.2 por ciento indicaron que creían que sí lo habría y 36.7 por ciento que no sabían. Las tres características más deseadas en el próximo presidente son; que ayude al pueblo (34.8 %), que sea honesto, no corrupto (20.1 %), y que abra fuentes de trabajo (18.3 %). Sólo 34.1 por ciento de los encuestados dijeron conocer a un candidato político que reuniera esas características específicas. Cristiani de ARENA obtiene un 26.2 por ciento de la intención de voto frente al 26.2 por ciento que da su preferencia a Chávez Mena del PDC, siguiendo a gran distancia Guillermo Ungo de la Convergencia Democrática, con un 5.9 por ciento. El resto de los candidatos apenas logra en conjunto un 2.9 por ciento de la intención de voto. Los salvadoreños entrevistados coinciden en que sólo los candidatos de ARENA y del PDC son los únicos que pueden aspirar a la presidencia. No obstante, la mayoría relativa (el 45.4 %) opina que Cristiani es el favorito a ganar, frente al 19. 7 por ciento que cree que el ganador será Chávez Mena.

This research explores how different types of distorting algorithms impact the Full-Reference image quality assessment, particularly when subjective quality evaluations are incorporated. We draw upon the TID2013 database, which contains 3000 images distorted by 24 distinct algorithms, in conjunction with Mean Opinion Scores (MOS) for quality ratings. We compare the results of Normalized Mutual Information (NMI) for image quality score with W2, based on Weibull distribution, the common PSNR similarity measure and MOS. We advocate for integrating of NMI into the repertoire of image quality assessment metrics.

An undergrad experiment for the at-home study of fluorescence: Extraction of quinine and chlorophyll from Cinchona tree bark
Authors: Granados-Chinchilla Fabio , Campos-Arguedas Luis Felipe
Published: June 2024

Herein we describe a method for the effective extraction and qualitative detection of quinine and chlorophyll. Both compounds can be successfully extracted from Cinchona tree bark (Cinchona pubescens Vahl) using nothing but household materials, usually cheap and easily acquired items available in any hardware store. During solid-liquid extraction with reflux, using an organic solvent is used to retain both compounds. Afterward, the compounds are partitioned between water and paint solvent. The organic phase containing the chlorophyll is saved, and the aqueous layer is acidified. Finally, an ultraviolet (UV) light is used to provoke fluorescence in both compounds.

Invigorating Globalized EFL Learners’ Reading Proficiency Growth through the Continual Support of Multimodal Strategy
Authors: Wijaya Kristian Florensio
Published: June 2024

As globalized EFL learners often elude themselves from participating in the designated reading learning activities prepared by their teachers due to the inevitable complexities, satiation, and frustration climates, the sustainable integration of a multimodal strategy is deemed as one of the essential digital learning approaches rewarding to be actualized by nowadays second language reading instructors. Previous researchers vehemently contended that with the support of a multimodal strategy, worldwide EFL learners no longer experience unpleasant reading learning climates since they interact with their digital texts enjoyably and meaningfully. This current small-scale library study is an actualization of the researcher's motivation to specifically reveal whether internalization of a multimodal strategy can reinforce globalized EFL learners' reading proficiency levels. To this end, the researcher employed a thematic analysis method in analyzing the specifically generated research results derived from 20 prior multimodal strategy scientific articles. To ascertain the credibility and relevancy of each analyzed research result, the researcher selected 20 already-published multimodal strategy articles ranging from 2018 until 2023. The thematically categorized research results highly advocated globalized second language reading instructors to arm language learners with the proper usage of a multimodal strategy to consistently promote more transformative reading learning enterprises in which EFL learners' targeted reading proficiency development can thrive to a greater level.
Effects of Arctic sea-ice concentration on surface radiative fluxes in four atmospheric reanalyses
Authors: Uhlíková Tereza , Vihma Timo , Karpechko Alexey Yu , Uotila Petteri
Published: June 2024

Abstract. Spatio-temporal variations and climatological trends in the sea-ice concentration (SIC) are highly important for the energy budget of the lower atmosphere and the upper ocean in the Arctic. To better understand the local, regional, and global impacts of the recent rapid sea-ice decline, one of the key issues is to quantify the interactions of SIC and the surface radiative fluxes. We analyse these effects utilising four global atmospheric reanalyses, ERA5, JRA-55, MERRA-2, and NCEP/CFSR and evaluate the uncertainties arising from inter-reanalysis differences in the sensitivity of the surface radiative fluxes to SIC. Using daily data over the period 1980–2021, the linear orthogonal-distance regression indicates similar sensitivity of surface upward longwave radiation to SIC in all reanalyses with the greatest sensitivity in the cold season November–April (over 150 W m-2 per -0.1 change in SIC) and up to 80 W m-2 per -0.1 change in SIC in May–October. We find that the effect of SIC on both surface upward longwave and shortwave radiation has mostly weakened in all seasons between the study periods of 1980–2000 and 2001–2021. The decrease in the sensitivity of upward longwave radiation to SIC can be attributed to the increasing surface temperature of sea ice, which dominated in the inner ice pack, and to the sea-ice decline, which dominated in the marginal ice zone. Approximately 80 % of the decadal decrease in upward shortwave radiation in May–July was caused by a decrease in surface albedo, controlled by SIC decrease, and the rest was caused by a decrease in downward shortwave radiation due to increase in cloudiness, mostly close to sea ice margins.
A Machine-learning Based Marine Planetary Boundary Layer (MPBL) Moisture Profile Retrieval Product from GNSS-RO Deep Refraction Signals
Authors: Gong Jie , Wu Dong Liang , Badalov Michelle , Ganeshan Manisha , Zheng Minghua
Published: June 2024

Abstract. Marine planetary boundary layer (MPBL) water vapor amount and gradient impact the global energy transport through directly affecting the sensible and latent heat exchange between the ocean and atmosphere. Yet, it is a well-known challenge for satellite remote sensing to profile MABL water vapor, especially when cloud or sharp gradient of water vapor are present. Wu et al. (2022) identified good correlations between Global Navigation Satellite System (GNSS) deep refraction signals (SNR) and the global MPBL water vapor specific humidity when the radio occultation (RO) signal is ducted by the moist PBL layer, and they laid out the underlying physical mechanisms to explain such a correlation. In this work, we apply a machine-learning/artificial intelligence (ML/AI) technique to realize pixel-level MPBL water vapor profiling. A convolutional neural network (CNN) model is trained using 20 months of global collocated hourly ERA-5 reanalysis and COSMIC1 1 Hz SNR observations between 975 – 850 hPa with 25 hPa vertical resolution, and then the model is applied to both COSMIC1 and COSMIC2 in other time ranges for independent retrieval and validation. Monte Carlo Dropout method was employed for the uncertainty estimation. Comparison against multiple field campaign radiosonde/dropsonde observations globally suggests SNR-retrieved water vapor consistently outperforms ERA-5 reanalysis and the Level-2 standard retrieval product at all six pressure levels between 975 hPa and 850 hPa, indicating real and useful information is gained from the SNR signal albeit training was performed against the reanalysis. The only exception is in the deep tropics where the fundamental assumption for SNR-retrieval to work is invalidated frequently by interactions among ocean surface, MPBL and shallow convections. Climatology and diurnal cycle of MPBL structure constructed from the ML-SNR technique is studied and compared to the reanalysis. Disparities of climatology suggest ERA-5 may systematically produces dry biases at high-latitudes, and wet biases in marine stratocumulus regions. The diurnal cycle amplitudes are too weak and off-phase in ERA-5, especially in Arctic and stratocumulus regions. These areas are particularly prone to PBL processes where this GNSS-SNR water vapor product may contribute the most.
Map of forest tree species for Poland based on Sentinel-2 data

Published: June 2024

Abstract. Accurate information on forest tree species composition is vital for various scientific applications, as well as for forest inventory and management purposes. Country-wide, detailed species maps are a valuable resource for environmental management, conservation, research, and planning. Here, we performed the classification of 16 dominant tree species and genera in Poland using time series of Sentinel-2 imagery. To generate comprehensive spectral–temporal information, we created Sentinel-2 seasonal aggregations known as spectral–temporal metrics (STMs) within the Google Earth Engine (GEE). STMs were computed for short periods of 15–30 d during spring, summer, and autumn, covering multi-annual observations from 2018 to 2021. The Polish Forest Data Bank served as reference data, and, to obtain robust samples with pure stands only, the data were validated through automated and visual inspection based on very-high-resolution orthoimagery, resulting in 4500 polygons serving as training and test data. The forest mask was derived from available land cover datasets in GEE, namely the ESA WorldCover and Dynamic World dataset. Additionally, we incorporated various topographic and climatic variables from GEE to enhance classification accuracy. The random forest algorithm was employed for the classification process, and an area-adjusted accuracy assessment was conducted through cross-validation and test datasets. The results demonstrate that the country-wide forest stand species mapping achieved an accuracy exceeding 80 %; however, this varies greatly depending on species, region, and observation frequency. We provide freely accessible resources, including the forest tree species map and training and test data: https://doi.org/10.5281/zenodo.10180469 (Grabska-Szwagrzyk, 2023a).
Modeling biochar effects on soil organic carbon on croplands in a microbial decomposition model (MIMICS-BC_v1.0)

Published: June 2024

Abstract. Biochar (BC) application to croplands aims to sequester carbon and improve soil quality, but its impact on soil organic carbon (SOC) dynamics is not represented in most land models used for assessing land-based climate change mitigation; therefore, we are unable to quantify the effects of biochar application under different climate or land management conditions. Here, to fill this gap, we implement a submodel to represent biochar in a microbial decomposition model named MIMICS (MIcrobial-MIneral Carbon Stabilization). We first calibrate and validate MIMICS with new representations of the density-dependent microbial turnover rate, adsorption of available organic carbon on mineral soil particles, and soil moisture effects on decomposition using global field-measured cropland SOC at 285 sites. We further integrate biochar in MIMICS by accounting for its effect on microbial decomposition and SOC sorption/desorption and optimize two biochar-related parameters in these processes using 134 paired SOC measurements with and without biochar addition. The MIMICS-biochar version can generally reproduce the short-term (≤ 6 years) and long-term (8 years) SOC changes after adding (mean addition rate of 25.6 t ha−1) biochar (R2= 0.79 and 0.97, respectively) with a low root-mean-square error (RMSE = 3.73 and 6.08 g kg−1, respectively). Our study incorporates sorption and soil moisture processes into MIMICS and extends its capacity to simulate biochar decomposition, providing a useful tool to couple with dynamic land models to evaluate the effectiveness of biochar application with respect to removing CO2 from the atmosphere.
Soil moisture modeling with ERA5-Land retrievals, topographic indices, and in situ measurements and its use for predicting ruts

Published: June 2024

Abstract. Spatiotemporal modeling is an innovative way of predicting soil moisture and has promising applications that support sustainable forest operations. One such application is the prediction of rutting, since rutting can cause severe damage to forest soils and ecological functions. In this work, we used ERA5-Land soil moisture retrievals and several topographic indices to model variations in the in situ soil water content by means of a random forest model. We then correlated the predicted soil moisture with rut depth from different trials. Our spatiotemporal modeling approach successfully predicted soil moisture with Kendall's rank correlation coefficient of 0.62 (R2 of 64 %). The final model included the spatial depth-to-water index, topographic wetness index, stream power index, as well as temporal components such as month and season, and ERA5-Land soil moisture retrievals. These retrievals were shown to be the most important predictor in the model, indicating a large temporal variation. The prediction of rut depth was also successful, resulting in Kendall's correlation coefficient of 0.61. Our results demonstrate that by using data from several sources, we can accurately predict soil moisture and use this information to predict rut depth. This has practical applications in reducing the impact of heavy machinery on forest soils and avoiding wet areas during forest operations.
Widespread flooding dynamics under climate change: characterising floods using grid-based hydrological modelling and regional climate projections
Authors: Griffin Adam , Kay Alison L. , Sayers Paul , Bell Victoria , Stewart Elizabeth , Carr Sam
Published: June 2024

Abstract. An event-based approach has been used to explore the potential effects of climate change on the spatial and temporal coherence of widespread flood events in Great Britain. Time series of daily mean river flow were generated using a gridded national-scale hydrological model (Grid-to-Grid) driven by a 12-member ensemble of regional climate projections from UK Climate Projections 2018 (UKCP18), for 30-year baseline (1980–2010) and future (2050–2080) time slices. From these, sets of widespread extreme events were extracted. The question of what defines a “widespread flood event” is discussed; here it was defined as an event exceeding an at-site 99.5th percentile (equivalent to 2 d per year) simultaneously over an area of at least 20 km2, with a maximum duration of 14 d. This resulted in a set of 14 400 widespread events: approximately 20 events per year, per ensemble member, per time slice. Overall, results have shown that events are more temporally concentrated in winter in the future time slice compared to the baseline. Distributions of event area were similar in both time slices, but the distribution of at-site return periods showed some heavier tails in the future time slice. Such information could be useful for adaptation planning and risk management for floods under climate change, but the potential future changes have to be interpreted in the context of some differences in event characteristics between the baseline climate-projection-driven model runs and an observation-driven model run. While the focus here is Great Britain, the methods and analyses described could be applied to other regions with hydrological models and climate projections of appropriate resolution.
Modernizing geospatial services: an investigation into modern OGC API implementation and comparative analysis with traditional standards in a web application
Authors: Chowdhury Sudipta , Schröder Dietrich , Ostadabbas Hamidreza , Hosseingholizadeh Mohammad , Friesecke Frank
Published: June 2024

Abstract. The study explores the transition from traditional geospatial service standards to modern Open Geospatial Consortium (OGC) API standards in web applications, focusing on urban development management. The main goal is to compare the performance and practical implications of integrating modern and traditional geospatial technologies. Two prototype system architectures were formulated based on the underlying principle of three-tier architectures. Database operations were facilitated by PostgreSQL (PostGIS), while server-side functionalities employed GeoServer and pygeoapi for data publication and OpenLayers served as the frontend for data visualization. The primary data source for this study is ALKIS (Authoritative Real Estate Cadastre Information System of Germany). The investigation encompasses two principal facets: a theoretical evaluation of two distinct server implementations utilizing conventional standards (GeoServer) and contemporary standards (pygeoapi), alongside a practical testing phase. Theoretical comparisons underscore GeoServer’s robustness, well-established user base, and comprehensive feature set, along with its highly efficient folder structure and detailed, user-friendly documentation. In contrast, pygeoapi is characterized by its emphasis on simplicity and utilization of modern technologies such as OpenAPI for implementing a RESTful API. During hands-on testing, it was observed that pygeoapi consistently exhibited longer rendering times than GeoServer. Moreover, as the feature count increased, both platforms showed a linear escalation in rendering times. To address prolonged rendering times in pygeoapi, incorporating vector tiles led to a significant reduction in rendering times. Regarding the affect of different data format, PostgreSQL (PostGIS) consistently outperforms other data formats used in pygeoapi, while Shapefile and PostgreSQL (PostGIS) perform well in GeoServer. This research aims to effectively integrate geospatial technologies, bridging the gap between established standards and emerging APIs in web applications.

Published: June 2024

Abstract. This study presents the City Transport Analyzer (CTA) QGIS plug-in designed for analyzing urban public transportation (PT) networks, exploiting GTFS data to investigate their multimodal nature. GTFS, a standardized format for PT schedules and geographic information, enables accurate data sharing, crucial for service analysis. The plug-in extracts GTFS data and converts it into GIS layers for analysis. It constructs a graph data structure using NetworkX, representing PT routes, with edges indicating travel time and transport type. Two key analyses are conducted: Service Area for accessibility and Nearby Stops Path for intermodality. The accessibility analysis determines reachable areas within specified time frames via PT and walking from one or more source points. It provides comprehensive insights into service coverage and the potential reach of PT networks within urban areas. The intermodality analysis assesses street paths for modal changes beyond PT nodes, offering valuable information on connectivity and potential PT usage patterns. Tested on case studies in Milan and Rio de Janeiro, the plug-in demonstrates utility in understanding metropolitan PT networks, but also room for improving the overall accuracy, usability and performances of the tool. The CTA plugin offers a flexible and user-friendly tool for studying service coverage, accessibility, and connectivity, aiding urban infrastructure analysis and planning. Future work aims to extend analyses to the whole city, including other city contexts. Ultimately, the CTA plugin contributes to a deeper understanding of urban PT networks and areas, facilitating informed decision-making in urban planning and infrastructure management.

Abstract. Rain-on-snow events can cause severe flooding in snow-dominated regions. These are expected to become more frequent in the future as climate change shifts the precipitation from snowfall to rainfall. However, little is known about how winter rainfall interacts with an evergreen canopy and affects the underlying snowpack. In this study, we document 5 years of rain-on-snow events and snowpack observations at two boreal forested sites of eastern Canada. Our observations show that rain-on-snow events over a boreal canopy lead to the formation of melt–freeze layers as rainwater refreezes at the surface of the sub-canopy snowpack. They also generate frozen percolation channels, suggesting that preferential flow is favoured in the sub-canopy snowpack during rain-on-snow events. We then used the multi-layer snow model SNOWPACK to simulate the sub-canopy snowpack at both sites. Although SNOWPACK performs reasonably well in reproducing snow height (RMSE = 17.3 cm), snow surface temperature (RMSE = 1.0 °C), and density profiles (agreement score = 0.79), its performance declines when it comes to simulating snowpack stratigraphy, as it fails to reproduce many of the observed melt–freeze layers. To correct for this, we implemented a densification function of the intercepted snow in the canopy module of SNOWPACK. This new feature allows the model to reproduce 33 % more of the observed melt–freeze layers that are induced by rain-on-snow events. This new model development also delays and reduces the snowpack runoff. In fact, it triggers the unloading of dense snow layers with small rounded grains, which in turn produces fine-over-coarse transitions that limit percolation and favour refreezing. Our results suggest that the boreal vegetation modulates the sub-canopy snowpack structure and runoff from rain-on-snow events. Overall, this study highlights the need for canopy snow property measurements to improve hydrological models in forested snow-covered regions.
Microstructure-based simulations of the viscous densification of snow and firn

Abstract. Accurate models for the viscous densification of snow (understood here as a density below 550 kg m−3) and firn (a density above 550 kg m−3) under mechanical stress are of primary importance for various applications, including avalanche prediction and the interpretation of ice cores. Formulations of snow and firn compaction in models are still largely empirical instead of using microstructures from micro-computed tomography to numerically compute the mechanical behavior directly from the physics at the microscale. The main difficulty of the latter approach is the choice of the correct rheology/constitutive law governing the deformation of the ice matrix, which is still controversially discussed. Being aware of these uncertainties, we conducted a first systematic attempt of microstructure-based modeling of snow and firn compaction. We employed the finite element suite Elmer FEM using snow and firn microstructures from different sites in the Alps and Antarctica to explore which ice rheologies are able to reproduce observations. We thereby extended the ParStokes solver in Elmer FEM to facilitate parallel computing of transverse isotropic material laws for monocrystalline ice. We found that firn densification can be reasonably well simulated across different sites assuming a polycrystalline rheology (Glen's law) that is traditionally used in glacier or ice sheet modeling. In contrast, for snow, the observations are in contradiction with this rheology. To further comprehend this finding, we conducted a sensitivity study on different ice rheologies. None of the material models is able to explain the observed high compactive viscosity of depth hoar compared to rounded grains having the same density. While, on one hand, our results re-emphasize the limitations of our current mechanical understanding of the ice in snow, they constitute, on the other hand, a confirmation of the common picture of firn as a foam of polycrystalline ice through microstructure-based simulations.
¿Pueden hablar las madres sobre política? Lazos entre violencia obstétrica, biopoder y memoria histórica en Madres paralelas (2021)
Authors: Alcalde Silveira Miguel
Published: June 2024

Madres paralelas (2021) supone una novedad tanto para su filmografía como para el tratamiento audiovisual de la memoria histórica española, sin precedentes en cuanto a la representación de las fosas comunes en las que el bando sublevado enterró a les civiles fusilades durante la Guerra Civil. No obstante, la recepción popular y profesional ha criticado la aparente desconexión entre esta trama y la historia principal: dos mujeres, madres primerizas con ideas y contextos muy diferentes de embarazo. El presente artículo, desde la perspectiva de las teorías queer, tomará como base de análisis fílmico las ideas acerca de la biopolítica, la sexualidad y el capitalismo farmacopornográfico formuladas por Michel Foucault y Paul B. Preciado. Concretamente, el objeto de estudio principal serán una serie de analogías apreciables entre las dos líneas argumentales mencionadas, que apuntan a una interrelación de las cuestiones de género y de la (post)memoria. En el marco temporal del desarrollo de una Ley de Memoria Histórica, el director habría conseguido fusionar dos objetivos: reivindicar el carácter restaurativo de dicha ley y la desnaturalización de algunos elementos de la norma cisheterosexual. Así, se intentará demostrar que Almodóvar continúa incluyendo motivos narrativos y estéticos que hacen a su público reflexionar sobre sus creencias, con Madres paralelas poniendo especial hincapié en motivos como la violencia obstétrica, el peso actual de crímenes de la Guerra Civil aún sin juzgar o el profundo papel de las estructuras de poder en la construcción de nuestras vidas.
Disidencias pasionales. El plano háptico del deseo queer en el cine de Pedro Almodóvar en Extraña forma de vida (2023)
Authors: Muñoz Torrecilla Néstor
Published: June 2024

Pasión y deseo son algunas de las primeras palabras que a alguien puede venirle a la mente al pensar en la filmografía de Pedro Almodóvar, como también lo pueden ser los homosexuales, el travestismo, el color rojo, Chus Lampreave o los teléfonos. Pedro Almodóvar es tradicionalmente reconocido como uno de los impulsores de la visibilidad queer en el cine español a través de sus películas desde el inicio de su carrera. La lluvia dorada de Alaska en  Pepi, Luci, Bom y otras chicas del montón (1980), el desnudo integral de Bibi Andersen en Kika (1993) o  el travestismo de Miguel Bosé en Tacones Lejanos (1999) con algunos de los ejemplos que se encuentran en la filmografía de Pedro Almodóvar que, lejos de limitarse a la representación de personajes homosexuales, ahonda en un gran abanico de disidencias sexoafectivas. Su última producción hasta la fecha, el mediometraje Extraña forma de vida (2023) el protagonizado por Ethan Hawke y Pedro Pascal, fue estrenado en salas a finales de mayo de 2023 tras su paso por el Festival de Cannes y ese mismo año se convirtió en el corto más taquillero de la historia del cine español. El corto, concebido como una supuesta respuesta a Brokeback Mountain (Ang Lee, 2005) aborda el reencuentro entre dos viejos amantes en un mar de interseccionalidades como la identidad sexual, el poder, el amor y el envejecimiento. Aparentemente no hay escenas visiblemente queer en este western, si atendemos a lo óptico. Es por ello que se estudiará a través de una mirada háptica la existencia de un texto queer en el mediometraje.  Se adentra así este estudio en un enfoque háptico, donde se erige el plano sensorial táctil por encima del visual. Esta elección estilística resulta en una elipsis consciente del sexo explícito, permitiendo una inmersión más profunda en las emociones de los personajes y en la exploración del deseo. Almodóvar, conocido por su transición de representaciones ópticas a una reflexión más profunda sobre las emociones y el deseo en su filmografía, muestra un cambio consciente hacia una cinematografía más reflexiva.

The study was undertaken to estimate the amount of energy used in different farm activities of irrigated boro rice (Oryza sataiva) cultivation in the four selected villages of Tangail district. Data was collected from the randomly selected farmers on the basis of pre-tested questionnaire. Input energy was calculated from human, animal, chemical fertilisers, operations of machinery and other input sources. A month-wise energy input calendar was constructed throughout the boro rice cultivation period from January to May. This study revealed that the draught power from power tiller sources was available for land preparation but the availability of human and draught animal power were not sufficient during the peak season. Total input energy was 19624 MJ/ha with fertiliser and irrigation as the major inputs and the output energy was 115659MJ/ha. The energy productivity and energy efficiency were 0.37 kg/MJ and 5.89 respectively.

In the last century, the studies of the world economy known to us, models for assessing multifaceted macroeconomic policies, the use of artificial intelligence and the 4th industrial revolution, as well as technological developments created the impression that humanity is no longer ready for the next crises in order to maximally resist and overcome the transition period, but the crisis situation created by the COVID-19 pandemic has proven that regardless of the level of economic development and economic growth rates recorded in recent years, shocks from the outside world can have a serious and sometimes profound impact on economic development.
