A CO2–Δ14CO2 inversion setup for estimating European fossil CO2 emissions
Authors: Gómez-Ortiz Carlos , Monteil Guillaume , Basu Sourish , Scholze Marko
Published: January 2025

Abstract. Independent estimation and verification of fossil CO2 emissions on a regional and national scale are crucial for evaluating the fossil CO2 emissions and reductions reported by countries as part of their nationally determined contributions (NDCs). Top-down methods, such as the assimilation of in situ and satellite observations of different tracers (e.g., CO2, CO, Δ14CO2, XCO2), have been increasingly used for this purpose. In this paper, we use the Lund University Modular Inversion Algorithm (LUMIA) to estimate fossil CO2 emissions and natural fluxes by simultaneously inverting in situ synthetic observations of CO2 and Δ14CO2 over Europe. We evaluate the inversion system by conducting a series of observing system simulation experiments (OSSEs). We find that in regions with a dense sampling network, such as western/central Europe, adding Δ14CO2 observations in an experiment where the prior fossil CO2 and biosphere fluxes are set to zero allows LUMIA to recover the time series of both categories. This reduces the prior-to-truth root mean square error (RMSE) from 1.26 to 0.12 TgC d−1 in fossil CO2 and from 0.97 to 0.17 TgC d−1 in biosphere fluxes, reflecting the true total CO2 budget by 91 %. In a second set of experiments using realistic prior fluxes, we find that in addition to retrieving the time series of the optimized fluxes, we are able to recover the true regional fossil CO2 budget in western/central Europe by 95 % and in Germany by 97 %. In all experiments, regions with low sampling coverage, such as southern Europe and the British Isles, show poorly resolved posterior fossil CO2 emissions. Although the posterior biosphere fluxes in these regions follow the seasonal patterns of the true fluxes, a significant bias remains, making it impossible to close the total CO2 budget. We find that the prior uncertainty of fossil CO2 emissions does not significantly impact the posterior estimates, showing similar results in regions with good sampling coverage like western/central Europe and northern Europe. Finally, having a good prior estimate of the terrestrial isotopic disequilibrium is important to avoid introducing additional noise into the posterior fossil CO2 fluxes.

Abstract. Fire is regarded as an essential climate variable, emitting greenhouse gases in the combustion process. Current global assessments of fire emissions traditionally rely on coarse remotely sensed burned-area data, along with biome-specific combustion completeness and emission factors (EFs). However, large uncertainties persist regarding burned areas, biomass affected, and emission factors. Recent increases in resolution have improved previous estimates of burned areas and aboveground biomass while increasing the information content used to derive emission factors, complemented by airborne sensors deployed in the tropics. To date, temperate forests, characterized by a lower fire incidence and stricter aerial surveillance restrictions near wildfires, have received less attention. In this study, we leveraged the distinctive fire season of 2022, which impacted western European temperate forests, to investigate fire emissions monitored by the atmospheric tower network. We examined the role of soil smoldering combustion responsible for higher carbon emissions, locally reported by firefighters but not accounted for in temperate fire emission budgets. We assessed the CO/CO2 ratio released by major fires in the Mediterranean, Atlantic pine, and Atlantic temperate forests of France. Our findings revealed low modified combustion efficiency (MCE) for the two Atlantic temperate regions, supporting the assumption of heavy smoldering combustion. This type of combustion was associated with specific fire characteristics, such as long-lasting thermal fire signals, and affected ecosystems encompassing needle leaf species, peatlands, and superficial lignite deposits in the soils. Thanks to high-resolution data (approximately 10 m) on burned areas, tree biomass, peatlands, and soil organic matter (SOM), we proposed a revised combustion emission framework consistent with the observed MCEs. Our estimates revealed that 6.15 Mt CO2 (±2.65) was emitted, with belowground stock accounting for 51.75 % (±16.05). Additionally, we calculated a total emission of 1.14 Mt CO (±0.61), with 84.85 % (±3.75) originating from belowground combustion. As a result, the carbon emissions from the 2022 fires in France amounted to 7.95 MtCO2-eq (±3.62). These values exceed by 2-fold the Global Fire Assimilation System (GFAS) estimates for the country, reaching 4.18 MtCO2-eq (CO and CO2). Fires represent 1.97 % (±0.89) of the country's annual carbon footprint, corresponding to a reduction of 30 % in the forest carbon sink this year. Consequently, we conclude that current European fire emission estimates should be revised to account for soil combustion in temperate forests. We also recommend the use of atmospheric mixing ratios as an effective monitoring system of prolonged soil fires that have the potential to re-ignite in the following weeks.

Abstract. Compared with the traditional mobile robots, the new concept mobile robots have greater deformation capability and richer mobile gait; similarly, they have a better capability to adapt to the environment. This paper presents a ring four-array rolling mechanism that consists of four anti-parallelogram mechanisms with revolute joints. The mechanism is connected by four anti-parallelograms in a looped configuration and has a not-totally-closed ring shape, whose external contour is similar to that of a quadrangular prism. The mechanism has planar and spherical patterns of locomotion, in which the planar pattern of locomotion includes the parallelogram rolling gait and the anti-parallelogram tumbling gait, and the spherical pattern of locomotion includes the spherical rolling gait. On this basis, the kinematic analysis of the two patterns of locomotion is carried out to obtain the positions of each point and the center of mass (CM) of the mechanism. The feasibility of the rolling locomotion of the mechanism is verified by the moving trajectory of the CM. According to analyzing the feasibility of the mechanism's obstacle-crossing and moving strategy, the mechanism is made to complete the switch between different motion modes. Through the establishment of a dynamic model and simulation, the analysis of the rolling gait of the mechanism is completed, and a prototype is made for experimental research. The results show that the anti-parallelogram ring four-array rolling mechanism has the basic rolling capability of linear movement and steering. Furthermore, in the initial state of the mechanism, the mechanism enables flexible switching between multiple rolling gaits.
Disentangling spring–neap suspended particulate matter (SPM) dynamics in estuaries
Authors: Dijkstra Yoeri M. , Bouwman Dennis D. , Schuttelaars Henk M.
Published: January 2025

Abstract. Suspended particulate matter (SPM) concentrations in estuaries have been observed to vary strongly over the spring–neap cycle through complex interactions between trapping and re-suspension. However, a systematic framework for analysing the processes causing this spring–neap SPM variability in general is missing. In this study we set up such a framework, consisting of three tiers. First, by studying the sediment transport capacity, how the locations of sediment trapping change over the spring–neap cycle is identified. Second, how the transport capacity affects the sediment stock and bottom pool of sediment is studied. This bottom pool only adapts gradually to the changing transport conditions, incorporating a lag or memory effect. Using a two-timescale analysis it is shown that this slow movement of the bottom pool is the leading source of such lag effects. Third, the SPM concentration is explained from an almost instantaneously balanced exchange between the bottom pool and the water column through re-suspension and deposition. We demonstrate the use of this framework on two model cases implemented in the idealised width-averaged iFlow model: an idealised test case where the sediment dynamics do not affect the water motion and a case representative of the Loire estuary, with strong feedback between sediment and the water motion through sediment-induced damping of turbulence. The first is illustrative as it allows a full understanding in terms of cause and effect between water motion, transport, and SPM concentration. In the more realistic Loire case, the SPM dynamics cannot be explained in terms of cause and effect but can explain the trapping locations and timing of maximum concentrations in a systematic way in terms of the governing physical mechanisms.
A hybrid ice-mélange model based on particle and continuum methods

Published: January 2025

Abstract. Ice mélange, a composite of sea ice and icebergs, can have a major influence on sea-ice–ocean interactions. However, ice mélange has not been represented in climate models because numerically efficient realizations do not exist. This motivates the development of a prototype of a dynamic hybrid ice-mélange model that we present in this paper. In our approach, icebergs are included as particles, while sea ice is treated as a continuum. To derive a joint continuum for ice mélange, we integrate particle properties into the sea-ice continuum. Thus, icebergs are viewed as thick, compact pieces of sea ice. The ice-mélange formulation is based on the viscous–plastic sea-ice rheology, which is currently the most widely used material law for sea ice in climate models. Starting from the continuum mechanical formulation, we modify the rheology such that icebergs are held together by a modified tensile strength in the material law. Due to the particle approach, we do not need highly resolved spatial meshes to represent the typical size of icebergs in ice mélange (< 300 m). Instead, icebergs can be tracked on a subgrid level, while the typical resolution of the sea-ice model can be maintained (≥10 km). This is an appealing property for computational efficiency and for an inclusion within large-scale models. In idealized test cases, we demonstrate that the proposed changes in the material law allow for a realistic representation of icebergs within the viscous–plastic sea-ice rheology. Furthermore, we show that subgrid dynamics, such as polynya formation due to grounded icebergs, can be modelled with the hybrid approach. Overall, this suggested extension of the viscous–plastic sea-ice model is a promising path towards the integration of ice mélange into climate models.
Ibn Khaldūn’s Muqaddima and the Maps of al-Idrīsī
Authors: Hiatt Alfred
Published: January 2025

It has long been noted that in compiling a geographical preface to his famous Muqaddima, Ibn Khaldūn relied on the maps contained in the twelfth-century geographer al-Idrīsī’s Nuzhat al-mushtāq fī ikhtirāq al-āfāq. Yet Ibn Khaldūn’s reading of nearly seventy regional maps of al-Idrīsī has not to date been the subject of a detailed examination. This article seeks, first, to establish patterns in Ibn Khaldūn’s map reading as recorded in the Muqaddima, noting the focus and direction of his reading as well as its omissions. In addition to his descriptions of the maps, it considers Ibn Khaldūn’s use of the text of the Nuzhat al-mushtāq and occasional examples of his updating and addition of information. Second, this analysis leads to a discussion of the significance—or lack thereof—of al-Idrīsī’s maps for the larger project of the Muqaddima: what role, in the end, did geography play within Ibn Khaldūn’s theory of history?

This study investigates the phenomenon of micro-moments and the behavior of making impulsive purchases among elderly women. This study aimed to identify the many micro-moments that cause impulsive purchase behavior. These micro-moments include boredom, social comparison, and a desire for self-reward. The study was conducted using the Digital Practice Tracing methodology with five women aged 50 and older. In addition, the study investigates the elements that influence older women's tendency to make impulsive purchases. These factors include individual characteristics, situational aspects, and marketing stimuli. According to the findings, older women are more likely to engage in impulsive purchasing in some circumstances, particularly when exposed to marketing stimuli that play on their desire for self-reward. In addition, the study underscores the necessity for marketers to recognize the specific features of older women as consumers and modify their marketing strategies according to such traits.

Published: January 2025

Pulau Onrust di Kepulauan Seribu memiliki sejarah panjang yang merefleksikan perubahan fungsi dalam berbagai periode pemerintahan kolonial Belanda. Pada awal abad ke-20, pulau ini berfungsi sebagai tempat karantina bagi jemaah haji untuk mencegah penyebaran penyakit menular, seperti kolera, yang dibawa dari Timur Tengah. Selain alasan kesehatan, kebijakan pembatasan ini juga digunakan sebagai alat kontrol sosial dan politik terhadap umat Islam, yang mencerminkan kepentingan kolonial dalam menjaga stabilitas kekuasaan. Penelitian ini bertujuan untuk menganalisis evolusi fungsi Pulau Onrust, mulai dari isolasi sebagai fasilitas karantina kesehatan hingga menjadi kamp tahanan politik pada tahun 1930-an, ketika fokus kolonial beralih dari pengawasan kesehatan ke penindakan terhadap aktivisme pergerakan kemandirian. Metode yang digunakan dalam penelitian ini adalah pendekatan historis, dengan menggali sumber-sumber arsip kolonial, dokumen sejarah, dan literatur yang relevan untuk memahami konteks perubahan fungsi pulau tersebut. Hasil penelitian menunjukkan bahwa perubahan peran Pulau Onrust mencerminkan dinamika kebijakan kolonial yang beradaptasi dengan tantangan sosial, politik, dan kesehatan pada masanya. Di era modern, Pulau Onrust telah menjadi situs warisan budaya yang penting, memicu perbincangan tentang pengelolaan sejarah kolonial di Indonesia. Penelitian ini memberikan kontribusi terhadap studi kolonial dan sejarah Indonesia dengan menawarkan perspektif baru mengenai strategi pengawasan dan pengendalian kolonial, serta warisan sejarahnya yang masih relevan dalam konteks modern.

A partir de la discusión académica abierta, la Red Nacional de Posgrados en Desarrollo Local (RENAPDEL) presenta en el presente texto una discusión sobre los cambios en el paradigma del desarrollo local. Concebido el desarrollo en el siglo XIX como mecanismo automático, y luego por la CEPAL en los años noventa del siglo pasado como una alternativa a las corrientes en boga del desarrollo centralizado a partir de formaciones nacionales, académicos mexicanos concluimos que el desarrollo es un fenómeno multidimensional, complejo y holístico en el cual el territorio no es un espacio abstracto y homogéneo, esto puesto que la geografía y la diversidad de los recursos naturales interactúan con lo social para generar condiciones que posibiliten la formación de sociedades regionales democráticas, con un alto nivel de vida y en donde la tecnología permita mantener crecimientos económicos sostenibles. La utopía de sociedades igualitarias con un profundo enraizamiento en la protección de la herencia cultural y ecológica parece renacer en la discusión actual sobre un nuevo paradigma de desarrollo.

Smart Automated Border Control System for Pakistan Airports Using ML-based Biometric Measures
Authors: Mazhar Moez
Published: January 2025

With the global population on the rise, the substantial increase in cross-border travel poses heightened security risks, the potential for the spread of pandemics such as COVID-19, congestion, delays in the check-in and checkout process, and various other challenges. This paper introduces a novel smart Automated Border Control system referred to as ABC system tailored for Pakistan. Employing advanced biometric technologies, including contactless facial and palm recognition systems, the proposed system aims to mitigate the spread of the COVID-19 pandemic at border crossings. A travel document reader system, leveraging Optical Character Recognition (OCR) technology, retrieves passport-based information from the database. State-of-the-art machine learning-based facial recognition algorithms and recent contactless palm recognition methodologies authenticate and validate passengers entering Pakistan. Furthermore, the proposed system is designed for seamless integration with existing services such as the Integrated Border Management System (IBMS) for immigration, Exit Control List (ECL), NADRA (National Database and Registration Authority) database, online Visa database, Passport database, and Advance Passenger Information (API) or Passenger Name Record (PNR) systems. By expediting the authentication process, the system significantly reduces delays in immigration procedures.

Published: January 2025

This study was aimed at determining the effects of wheat gluten, corn gluten and soybean meal, incorporated into feed as protein sources, on the hepatic tissue of rats, based on the investigation of histopathological parameters (degeneration, inflammation, biliary hyperplasia and fat droplets), immunohistochemical parameters (transglutaminase, gliadin, IgA, IgG, CD4 and CD8), and the serum levels of hepatic enzymes [(aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH)]. Three groups, referred to as Wheat Group, Group Corn and Group Soybean, were established, and were given high levels of wheat gluten, corn gluten and soybean meal as protein sources in the feed, respectively. The study material comprised forty–eight 20–day–old female Sprague Dawley rats. In the group, which received dietary wheat gluten, the hepatic tissue presented with numerically higher histopathological and immunohistochemical parameters on day 45 of the study, and numerically higher histopathological parameters on day 165 of the study (P>0.05). On day 165 of the study, when compared to Groups Corn and Soybean, Group Wheat displayed a significantly different level of sensitivity to immunohistochemical parameters (transglutaminase, gliadin, IgA, IgG, CD4 and CD8). It was determined that gluten significantly reduced the activity of the liver enzymes LDH and AST. In result, it was ascertained that rats, not carrying the genes HLA–DQ2 and DQ8, when fed on a ration incorporated with a high level of wheat gluten, displayed slightly affected hepatic tissue histopathological parameters and significantly increased immunohistochemical parameters (transglutaminase, gliadin, IgA, IgG, CD4 and CD8).

La presente investigación tuvo como objetivo comparar las características morfométricas macroscópicas post mortem de las unidades materno fetales (UMFs) en cada cuerno uterino (CU) y su relación con la concentración de progesterona (P4) durante los primeros 35 días de gestación en la cobaya (Cavia porcellus). Se utilizaron 20 cobayas de línea peruana, peso medio de 964,5 ± 33,99 gramos y una condición corporal de 2,6 ± 0,11. La evaluación post mortem se ejecutó en 5 momentos diferentes de la gestación (días 15, 20, 25, 30 y 35), sacrificando 4 cobayas en cada uno. Se tomaron muestras sanguíneas para medir los niveles de P4 y luego se extrajo el aparato reproductor, identificando el cuerno derecho (CUD) e izquierdo (CUI), los cuales se dividieron en tres secciones: caudal, medio, craneal, para describir el lugar de la implantación embrionaria. Se determinó el volumen y peso de UMFs, se midió el diámetro de la placenta (DPL), diámetro de saco gestacional (DSG) y la longitud corona rabadilla (CR). Los resultados demostraron un mayor porcentaje de implantación en CUD (66,8 %) en relación al CUI (33,2 %) y mayor frecuencia de implantaciones en la parte caudal de ambos cuernos (CpD=32,5 % y CpIZ=22,1 %), el volumen de la UMFs presentó un crecimiento progresivo, aunque disminuyó al día 30, recuperándose nuevamente en el día 35. Un patrón similar se registró en el desarrollo del DPL, DSG y CR. La concentración de P4 fue de 68,4 ± 3,41 ng·mL-1 en el día 15 y de 63,7 ± 2,20 ng·mL-1 en el día 35. En conclusión, las gestaciones se presentaron con mayor frecuencia en el cuerno derecho, con implantaciones localizadas en las posiciones caudal y media de ambos cuernos. El desarrollo embrión mostró un crecimiento lento pero progresivo en los primeros 20 días, acelerándose al día 30, impulsado por la funcionalidad de la placenta.

Surfaktan merupakan senyawa kimia yang digunakan untuk meningkatkan pemulihan minyak,terutama pada reservoir yang sudah tua atau sulit untuk dieksploitasi. Dengan kemampuannya untuk mengurangi tegangan antarmuka,meningkatkan wettabilitas batuan dan memobilisasi minyak yang terperangkap,surfaktan ini memainkan peran penting dalam teknik Enhanced Oil Recovery (EOR) untuk meningkatkan recovery factor. Lapangan Kawengan terletak di Provinsi Jawa Tengah, Indonesia, dan merupakan salah satu lapangan minyak strategis. Setelah bertahun-tahun diproduksikan, Lapangan Kawengan telah mengalami penurunan produksi minyak. Metode primary recovery dan secondary recovery sudah dipakai namun tidak lagi mampu meningkatkan perolehan minyak secara signifikan, sehingga diperlukan metode Enhanced Oil Recovery (EOR) seperti injeksi surfaktan. Maka dilakukan uji lab menggunakan sampel core dan minyak dari Kawengan. Pada penelitian ini menggunakan metode imbibisi spontan dengan beberapa fluida injeksi berupa sintetic brine, surfaktan kosentrasi 1%, 1,5% dan 2% guna menjadi pembanding bagaimana hasil ekstraksi minyak dari core yang telah dijenuhkan. Bersarkan hasil dari beberapa pengujian disimpulkan bahwa penggunaan surfaktan 2% pada imbibisi menunjukan hasil yang lebih baik dengan recovery factor 48%. Penelitian ini dapat digunakan sebagai pedoman dalam pengembangan pengujian Surfaktan terkhusunya pada sampel minyak lapangan Kawengan.

Negotiating Rights to Inhabit Common Lands for Housing in Two Cities of South India
This paper presents a framework for understanding the everyday political dynamics of commoning initiated by residents to secure their claims to ‘common land’ in urbanising localities. This paper puts forward the proposition that a spatialised approach would serve to reveal the extent to which unique socio-political and geographical factors exert an influence upon the dynamics of collective actions (commoning). It examines the experience of households in two squatter settlements on the outskirts of two South Indian cities: Villupuram, a medium-sized town in the state of Tamil Nadu, and Bangalore, a large metropolis in the state of Karnataka. It demonstrates how common land could serve as a foundation for the inclusion of poor communities within the city. The two cases presented in this paper reflect a trend observed in Indian cities since the mid-1990s, whereby rural common lands in urbanised localities, previously allocated to poor households for housing, have been targeted for more profitable development, eventually justified by environmental arguments. Consequently, those in poverty are compelled to compete with more powerful actors in order to assert their right to the common land they occupy for the purpose of housing. The two case studies demonstrate the capacity of such communities to unite and engage in practical political actions to regularise their settlements and dwellings. We describe their engagement with multiple government institutions across the rural and urban continuum and illustrate the influence of contextual factors, including geographical and temporal factors, in shaping the unique and diverse trajectories of commoning.

Amidst globalization, there is an emerging issue to strengthen students’ local identity since the trend of English teaching is shifting from using English-speaking culture materials into integrating local culture. As a multicultural country, Indonesia has great potential to incorporate local culture into education. This concept, known as ethnopedagogy, utilizes local culture to strengthen genuine Indonesian education, considering that local culture is a source of innovation and skills that can be empowered in the classroom. Therefore, this research investigates the insights of young learners (aged 10-11 years old) regarding Sundanese cultural integration in their English language learning. Guided by an interpretivist paradigm, this qualitative case study seeks to explore the students’ learning experiences and insights. This research involved a class of English for Young Learners class in one of English language courses in Bandung, West Java, Indonesia. Data were collected using classroom observation, interview, and field notes. The findings revealed that integrating Sundanese culture into English lessons was a novel experience for the students, differing significantly from their school-based English learning. Furthermore, this approach fostered a sense of participation in preserving culture since students had better understanding about their own culture. In addition, it contributed to improvement in attention span, excitement, memory, knowledge, English score at school, and students relationship. Also, parents appreciated Sundanese culture integration into their children’s English learning. They perceived it as a means to preserve Sundanese culture while also support their cultural values and educational foundation at home and help them navigate the challenges of modern society.

The science process skills of elementary school students in Langsa city are still relatively low, despite these skills being a crucial element in science education based on the Merdeka curriculum. Additionally, teachers have reported several challenges, including the presence of abstract science material, textbooks that use two-dimensional visualizations, and the inability to practice all science concepts. This research developed the SIAR book (Interactive Science with Augmented Reality) to enhance science process skills. The study produced an elementary school science book that includes observational activities and integrates augmented reality (AR) to present more concrete three-dimensional visualizations. The objectives of this study were to create a valid and effective SIAR book product for improving science process skills. This research employed the ADDIE model (Analysis, Design, Development, Implementation, Evaluation) for development. Participants included three expert validators and 100 elementary school students. The results indicated that: (1) the SIAR book is highly valid for improving science process skills, with a validity score of 96.11%; (2) the SIAR book is effective in enhancing science process skills, achieving a gain score of 0.76, which falls within the high criteria. Based on these findings, it can be concluded that a book integrated with AR can assist students in improving their science process skills. As science process skills improve, students' understanding of science also increases. Therefore, science education in schools should leverage digital technology, as it meets students' needs and facilitates the learning process in science.

Introduction: The purpose of this study was to assess the impact of Reflexive Performance Resets (RPR) compared to a dynamic warm-up and contrast training on acute athletic performance.
Methods: Participants were athletes competing in the National Association of Intercollegiate Athletics (NAIA) collegiate athletes (male: 7, female: 2; average height: 180.64 ± 5.89 cm; average body mass: 76.29 ± 6.57 kg; age: 21.22 ± 1.71years; 1RM trap bar deadlift: 153.95 ± 28.35 kg; deadlift/body mass ratio: 2.02 ± 0.41). Participants in the study completed four different potentiation protocols: control (cycling), contrast training, dynamic warm-up, and RPR. The participants completed each protocol on separate days before performing a countermovement jump, which assessed mean peak displacement, acceleration, velocity, and power on a force plate, and a T-test assessed the change of direction performance.
Results: A repeated measures ANOVA and independent t-tests were used to assess interactions and main effects between the protocols. A significant main effect was found when comparing the dynamic warm-up and RPR protocols in mean peak displacement (Dynamic: 0.42 ± 0.05 m; RPR: 0.36 ± 0.06 m; p = 0.001; d = 1.41; 95% Cl [-0.66,0.76), velocity (Dynamic: 2.85 ± .17 m/s; RPR: 2.7 ± .19 m/s; p =0.003; d = 1.41; 95% Cl [-0.03,0.33], and power (Dynamic: 4258 ± 541.4 w; RPR: 3964 ± 597.91 w; p = 0.005; d = 1.41; 95% Cl [-275.74,864.20]). There was also a significant main effect when comparing mean peak power between the dynamic warm-up and control protocols (Dynamic: 4258.24 ± 541.4 w; RPR: 4063.56 ± 474.41 w; p = 0.04; d = 0.38; 95% Cl [-314, 508.7]) There were no significant differences between the dynamic warm-up and RPR protocols in mean peak acceleration (Dynamic: 13.32 ± 2.4 m/s2; RPR: 13.12 ± 3.28 m/s2; p = .310 or mean peak T-test (Dynamic: 10.31 ± .78 s; RPR 10.1 ± .77 s; p = .464.
Conclusions: A dynamic warm-up was shown to be most effective for improving acute countermovement jump performance when compared to RPR, contrast training, and a control protocol.

Published: January 2025

Urbanization is a significant human activity that changes the Earth’s land landscape and the degree to which urbanization affects temperature variation depends critically on the built environment, population density and size, human activity, and socioeconomic characteristics of a metropolis. It has long been known that patterns of LULC and thermal characteristics are related, and this link can be used to examine how urbanization affects the urban thermal environment. This research uses a time series of Sentinel and Landsat satellite images to examine the traits of urban growth and how they affect the surface temperature of the land in Dibrugarh District of Assam, India, between 1993 and 2023. The Normalized Difference Vegetation Index (NDVI) has been falling to the negative side, and less green, healthy vegetation has been recorded. Only the year 2003 recorded the availability of healthy vegetation ranging above 0.6 in the NDVI matrix. Due to deforestation and other anthropogenic activities, the average earth surface temperature went up to 0.96 °C from 1993 to 2023, with an average of 0.04 °C annually. These are the results of decreasing green vegetation. The LULC data show an increase of 177.155 km2 of built-up areas with a significant decrease in waterbodies and green vegetation. Although the climatic condition of the district is totally dominated by the monsoon, this temperature rise may cause problems in the near future and will impact agriculture and environmental sustainability.
