Various scholars acknowledged that formative assessment play a vital role in increasing students’ academic achievement. The main purpose of this study was to explore formative assessment practices in public secondary schools in Kicukiro District. The specific objectives of the study were to investigate how teachers plan for formative assessment in public secondary schools in Kicukiro district, to discover how teachers use formative assessment techniques in electing students learning evidence in public secondary schools in Kicukiro district and to assess how teachers provide formative assessment feedback to students in public secondary schools in Kicukiro district. The study used descriptive survey research design. The study was guided by Sadler’s theory of formative assessment founded in 1989. The target population of the study was 220 teachers and 13 deputy head teachers in charge of studies. A sample of 142 teachers were selected using simple random sampling while 13 deputy head teachers in charge of studies were included in the study purposively. Questionnaires, semi-structured interview and lesson observation checklist were used as research instruments in collecting data from respondents. Quantitative data were analysed using descriptive statistics such as means and standard deviations whereas thematic analysis was used for analysing qualitative data.  The quantitative data were presented in tables while qualitative data were presented in the text. The findings indicate that the practices related to planning for formative assessment (M=2.41, SD=1.01) are rarely practiced in public secondary schools in Kicukiro District. It was also revealed that practices related to eliciting evidences of students’ learning (M=2.76, SD=1.11) were practiced sometimes. Finally, it was revealed practices related to formative assessment feedback (M=2.33, SD=1.01) were rarely done. The study recommended that National Examination and School Inspection Authority should strengthen the practices of formative assessment at school levels. Future researchers were recommended to replicate the study in other region beyond Kicukiro District.

GRILAGEM EM TERRAS PÚBLICAS
Authors: Oliveira Alessandra Souto de Souza , Feller Thiago de Almeida
Published: May 2024

A grilagem de terras públicas é uma prática ilegal que ocorre quando indivíduos ou grupos buscam obter posse de terras pertencentes ao Estado de maneira fraudulenta. Geralmente, isso envolve a falsificação de documentos, como títulos de propriedade e certidões de posse, para aparentar uma ocupação legítima da terra. No Brasil, essa prática é especialmente prevalente na região amazônica, onde a vasta extensão territorial e a fragilidade dos sistemas de controle propiciam a ação de grileiros. Os impactos da grilagem são significativos e abrangem áreas ambientais, sociais e econômicas. Ambientalmente, está associada ao desmatamento ilegal e à degradação ambiental. Socialmente, contribui para conflitos de terra, violência e deslocamento de comunidades tradicionais. Economicamente, prejudica o desenvolvimento sustentável e perpetua a concentração de terras nas mãos de poucos. As autoridades brasileiras têm implementado medidas para combater a grilagem, como fiscalização mais rigorosa e políticas de regularização fundiária, porém o problema persiste devido à sua complexidade e aos interesses econômicos por trás da prática. Para isto, a pesquisa se fez baseada em extensa revisão bibliográfica que incluiu importantes artigos científicos, relatórios governamentais, livros e documentos acadêmicos que datam desde 1993 a 2024. Foram considerados estudos que abordem desde o Brasil Colônia com a apropriação de terras griladas até a presente data no que tange a regularização fundiária e leis que rege a regularização da grilagem em terras públicas.
Modeling the influence of carbon branching structure on secondary organic aerosol formation via multiphase reactions of alkanes
Authors: Madhu Azad , Jang Myoseon , Jo Yujin
Published: May 2024

Abstract. Branched alkanes represent a significant proportion of hydrocarbons emitted in urban environments. To accurately predict the secondary organic aerosol (SOA) budgets in urban environments, these branched alkanes should be considered as SOA precursors. However, the potential to form SOA from diverse branched alkanes under varying environmental conditions is currently not well understood. In this study, the Unified Partitioning Aerosol Phase Reaction (UNIPAR) model is extended to predict SOA formation via the multiphase reactions of various branched alkanes. Simulations with the UNIPAR model, which processes multiphase partitioning and aerosol-phase reactions to form SOA, require a product distribution predicted from an explicit gas kinetic mechanism, whose oxygenated products are applied to create a volatility- and reactivity-based αi species array. Due to a lack of practically applicable explicit gas mechanisms, the prediction of the product distributions of various branched alkanes was approached with an innovative method that considers carbon lengths and branching structures. The αi array of each branched alkane was primarily constructed using an existing αi array of the linear alkane with the nearest vapor pressure. Generally, the vapor pressures of branched alkanes and their oxidation products are lower than those of linear alkanes with the same carbon number. In addition, increasing the number of alkyl branches can also decrease the ability of alkanes to undergo autoxidation reactions that tend to form low-volatility products and significantly contribute to alkane SOA formation. To account for this, an autoxidation reduction factor, as a function of the degree and position of branching, was applied to the lumped groups that contain autoxidation products. The resulting product distributions were then applied to the UNIPAR model for predicting branched-alkane SOA formation. The simulated SOA mass was compared to SOA data generated under varying experimental conditions (i.e., NOx levels, seed conditions, and humidity) in an outdoor photochemical smog chamber. Branched-alkane SOA yields were significantly impacted by NOx levels but insignificantly impacted by seed conditions or humidity. The SOA formation from branched and linear alkanes in diesel fuel was simulated to understand the relative importance of branched and linear alkanes with a wide range of carbon numbers. Overall, branched alkanes accounted for a higher proportion of SOA mass than linear alkanes due to their higher contribution to diesel fuel.
A survey of methane point source emissions from coal mines in Shanxi province of China using AHSI on board Gaofen-5B
Authors: He Zhonghua , Gao Ling , Liang Miao , Zeng Zhao-Cheng
Published: May 2024

Abstract. Satellite-based detection of methane (CH4) point sources is crucial in identifying and mitigating anthropogenic emissions of CH4, a potent greenhouse gas. Previous studies have indicated the presence of CH4 point source emissions from coal mines in Shanxi, China, which is an important source region with large CH4 emissions, but a comprehensive survey has remained elusive. This study aims to conduct a survey of CH4 point sources over Shanxi's coal mines based on observations of the Advanced Hyperspectral Imager (AHSI) on board the Gaofen-5B satellite (GF-5B/AHSI) between 2021 and 2023. The spectral shift in centre wavelength and change in full width at half-maximum (FWHM) from the nominal design values are estimated for all spectral channels, which are used as inputs for retrieving the enhancement of the column-averaged dry-air mole fraction of CH4 (ΔXCH4) using a matched-filter-based algorithm. Our results show that the spectral calibration on GF-5B/AHSI reduced estimation biases of the emission flux rate by up to 5.0 %. We applied the flood-fill algorithm to automatically extract emission plumes from ΔXCH4 maps. We adopted the integrated mass enhancement (IME) model to estimate the emission flux rate values from each CH4 point source. Consequently, we detected CH4 point sources in 32 coal mines with 93 plume events in Shanxi province. The estimated emission flux rate ranges from 761.78 ± 185.00 to 12 729.12 ± 4658.13 kg h−1. Our results show that wind speed is the dominant source of uncertainty contributing about 84.84 % to the total uncertainty in emission flux rate estimation. Interestingly, we found a number of false positive detections due to solar panels that are widely spread in Shanxi. This study also evaluates the accuracy of wind fields in ECMWF ERA5 reanalysis by comparing them with a ground-based meteorological station. We found a large discrepancy, especially in wind direction, suggesting that incorporating local meteorological measurements into the study CH4 point source are important to achieve high accuracy. The study demonstrates that GF-5B/AHSI possesses capabilities for monitoring large CH4 point sources over complex surface characteristics in Shanxi.
Direct foliar phosphorus uptake from wildfire ash
Authors: Lokshin Anton , Palchan Daniel , Gross Avner
Published: May 2024

Abstract. Atmospheric particles originating from combustion byproducts (burned biomass or wildfire ash) are highly enriched in nutrients such as P, K, Ca, Mg, Fe, Mn, and Zn. Over long timescales, deposited wildfire ash particles contribute to soil fertility by replenishing soil nutrient reservoirs. However, the immediate nutritional effects of freshly deposited fire ash on plants are mostly unknown. Here, we study the influence of fire ash on plant nutrition by applying ash separately on a plant's foliage or to its substrate around the roots. We conducted experiments on chickpea model plants under ambient and elevated CO2 levels, which reflect current and future climate scenarios. We found that plants can utilize fire ash P and Ni through their leaves by direct nutrient uptake from particles captured on their foliage but not via their roots, both under ambient and elevated CO2 levels. These results indicate that over a short timescale, plants effectively uptake P from fire ash only via the foliage rather than the root pathway, which is possibly due to low bioavailability or limited contact between fire ash particles and the roots. According to many previous studies, elevated levels of CO2 will reduce the ionome of plants due to the partial inhibition of the key root uptake mechanism, thus increasing the significance of foliar nutrient uptake in a future climate. Furthermore, the role of fire ash is expected to increase in the future world, thus giving a competitive advantage to plants that can utilize fire ash P from the foliar pathway, as fire ash P is a particularly efficient and important source of P.
A Framework for Automated Supraglacial Lake Detection and Depth Retrieval in ICESat-2 Photon Data Across the Greenland and Antarctic Ice Sheets
Authors: Arndt Philipp Sebastian , Fricker Helen Amanda
Published: May 2024

Abstract. Supraglacial lakes on the ice sheets have been linked to ice shelf collapse in Antarctica and accelerated flow of grounded ice in Greenland. However, it is difficult to quantify the impact of supraglacial lakes on ice dynamics accurately enough to predict their contribution to future mass loss and sea level rise. This is largely because ice-sheet-wide assessments of meltwater volumes rely on models that are poorly constrained due to a lack of accurate depth measurements. Various recent case studies have demonstrated that accurate supraglacial lake depths can be obtained from ICESat-2’s ATL03 photon-level data product. ATL03 comprises hundreds of terabytes of unstructured point cloud data, which has made it challenging to use this bathymetric capability at scale. Here, we present two new algorithms – Flat Lake and Underlying Ice Detection (FLUID) and Surface Removal and Robust Fit (SuRFF) – which together provide a fully automated and scalable method for lake detection and depth determination from ATL03 data, and establish a framework for its large-scale implementation using distributed high-throughput computing. We report FLUID/SuRFF algorithm performance over two regions known to have significant surface melt – Central West Greenland and Amery Ice Shelf catchment in East Antarctica – during two melt seasons. FLUID/SuRFF reveals a total of 1249 lakes up to 25 m deep, with more water during higher melt years. In absence of ground truth data, manual annotation of test data suggests that our method reliably detects melt lakes whenever a bathymetric signal is discernible, and estimates water depths with a mean absolute error of 0.28 m. These results imply that our proposed framework has the potential to generate a comprehensive data product of accurate meltwater depths across both ice sheets.

Published: May 2024

Abstract. We use a process-based biogeochemistry model to simulate the fire impacts on soil thermal and hydrological dynamics and carbon budget of forest ecosystems in Northern Eurasia during 2003–2016 based on satellite-derived burn severity data. We find that fire severity generally increases in this region during the study period. Simulations indicate that fires increase soil temperature by 0.2–0.5 °C through removing the ground moss and surface soil organic matter, especially in Asian part of the region. Fires also increase water runoff by about 131 million m3 yr-1 through reducing post-fire evapotranspiration, leading to a higher regional river discharge. Fires remove 1.7 Pg C of ecosystem carbon through combustion emissions during this period and reduce net ecosystem production from 106.4 to 66.1 Tg C yr-1. Fires lead the forest ecosystems to lose 2.3 Pg C, shifting the forests from a carbon sink to a source in this period. Our study highlights the importance of wildfires in affecting soil thermal and hydrological and carbon dynamics in boreal forests.
The anti-cyclonic gyre around the Qingdao cold water mass in the China marginal sea
Authors: Lin Lin , von Storch Hans , Ding Yang
Published: May 2024

Abstract. The circulation structure surrounding the Qingdao cold water mass in 2019 was investigated via three-dimensional numerical simulations. The study reveals that a cold pool appears in early spring and reaches its peak in late May, and this pool is accompanied by a local anticyclonic gyre. Momentum diagnostics are utilized to determine the relationship between the cold pool and this gyre. The momentum results reveal that vertical friction cannot be ignored due to the shallow topography and surface wind stress; as a result, the geostrophic balance is no longer applicable in the Qingdao cold water mass region. Consequently, the temperature and salinity gradients induced by the cold pool structure do not directly result in the anticyclonic gyre. Additional numerical experiments are conducted in which tidal forcing or wind forcing is excluded to understand the formation mechanism of this anticyclonic gyre. The t test results show that the difference between the control run and the ensemble experiments without tidal forcing (or without wind forcing) is statistically significant. Thus, both tidal forcing and wind forcing have a significant influence on the anticyclonic structure, although their impacts are different. Without tidal forcing, an unrealistic strong current appears throughout the domain. Moreover, the direction of the eastern side of the anticyclonic circulation is reversed. On the other hand, the wind forcing contributes to the magnitude of the anticyclonic circulation, especially in the western portion of the anticyclonic circulation. Additionally, subcirculation occurs vertically around the Qingdao cold water mass and is influenced by both wind and tidal forcings.
Brazilian Atmospheric Inventories – BRAIN: a comprehensive database of air quality in Brazil
Authors: Hoinaski Leonardo , Will Robson , Ribeiro Camilo Bastos
Published: May 2024

Abstract. Developing air quality management systems to control the impacts of air pollution requires reliable data. However, current initiatives do not provide datasets with large spatial and temporal resolutions for developing air pollution policies in Brazil. Here, we introduce the Brazilian Atmospheric Inventories (BRAIN), the first comprehensive database of air quality and its drivers in Brazil. BRAIN encompasses hourly datasets of meteorology, emissions, and air quality. The emissions dataset includes vehicular emissions derived from the Brazilian Vehicular Emissions Inventory Software (BRAVES), industrial emissions produced with local data from the Brazilian environmental agencies, biomass burning emissions from FINN – Fire INventory from the National Center for Atmospheric Research (NCAR), and biogenic emissions from the Model of Emissions of Gases and Aerosols from Nature (MEGAN) (https://doi.org/10.57760/sciencedb.09858, Hoinaski et al., 2023a; https://doi.org/10.57760/sciencedb.09886, Hoinaski et al., 2023b). The meteorology dataset has been derived from the Weather Research and Forecasting Model (WRF) (https://doi.org/10.57760/sciencedb.09857, Hoinaski and Will, 2023a; https://doi.org/10.57760/sciencedb.09885, Hoinaski and Will, 2023c). The air quality dataset contains the surface concentration of 216 air pollutants produced from coupling meteorological and emissions datasets with the Community Multiscale Air Quality Modeling System (CMAQ) (https://doi.org/10.57760/sciencedb.09859, Hoinaski and Will, 2023b; https://doi.org/10.57760/sciencedb.09884, Hoinaski and Will, 2023d). We provide gridded data in two domains, one covering the Brazilian territory with 20×20 km spatial resolution and another covering southern Brazil with 4×4 km spatial resolution. This paper describes how the datasets were produced, their limitations, and their spatiotemporal features. To evaluate the quality of the database, we compare the air quality dataset with 244 air quality monitoring stations, providing the model's performance for each pollutant measured by the monitoring stations. We present a sample of the spatial variability of emissions, meteorology, and air quality in Brazil from 2019, revealing the hotspots of emissions and air pollution issues. By making BRAIN publicly available, we aim to provide the required data for developing air quality policies on municipal and state scales, especially for under-developed and data-scarce municipalities. We also envision that BRAIN has the potential to create new insights into and opportunities for air pollution research in Brazil.​​​​​​​

Abstract. The single-column model, with its advantages of low computational cost and fast execution speed, can assist users in gaining a more intuitive understanding of the impact of parameters on the simulated results of climate models. It plays a crucial role in the study of parameterization schemes, allowing for a more direct exploration of the influence of parameters on climate model simulations. In this paper, we employed various methods to conduct sensitivity analyses on the 11 parameters of the Single Column Atmospheric Model (SCAM). We explored their impact on output variables such as precipitation, temperature, humidity, and cloud cover, among others, across five test cases. To further expedite experimentation, we utilized machine learning methods to train surrogate models for the aforementioned cases. Additionally, three-parameter joint perturbation experiments were conducted based on these surrogate models to validate the combined parameter effects on the results. Subsequently, targeting the sensitive parameter combinations identified from the aforementioned experiments, we further conducted parameter tuning for the corresponding test cases to minimize the discrepancy between the results of SCAM and observational data. Our proposed method not only enhances model performance but also expedites parameter tuning speed, demonstrating good generality at the same time.
A global behavioural model of human fire use and management: WHAM! v1.0

Published: May 2024

Abstract. Fire is an integral ecosystem process and a major natural source of vegetation disturbance globally. Yet at the same time, humans use and manage fire in diverse ways and for a huge range of purposes. Therefore, it is perhaps unsurprising that a central finding of the first Fire Model Intercomparison Project was simplistic representation of humans is a substantial shortcoming in the fire modules of dynamic global vegetation models (DGVMs). In response to this challenge, we present a novel, global geospatial model that seeks to capture the diversity of human–fire interactions. Empirically grounded with a global database of anthropogenic fire impacts, WHAM! (the Wildfire Human Agency Model) represents the underlying behavioural and land system drivers of human approaches to fire management and their impact on fire regimes. WHAM! is designed to be coupled with DGVMs (JULES-INFERNO in the current instance), such that human and biophysical drivers of fire on Earth, and their interactions, can be captured in process-based models for the first time. Initial outputs from WHAM! presented here are in line with previous evidence suggesting managed anthropogenic fire use is decreasing globally and point to land use intensification as the underlying reason for this phenomenon.

Published: May 2024

Abstract. Recent advances in NMR fragment screening use sample illumination to boost NMR sensitivity, reduce measurement time to a few seconds, and reduce sample concentration to a few micromolars. Nevertheless, the absence of a fully automated solution to measure several hundreds of samples with photoinduced hyperpolarization limits the large-scale applicability of the method. We present a setup to couple an optical fiber with a cryogenic probe using the flow-cell accessory port. This setup is compatible with commercially available autosamplers, enabling the fully automated measurement of several hundreds of samples per day.

Spasavanje savskih žrtava od zaborava i negiranja
Authors: Byford Jovan
Published: May 2024

Članak istražuje istorijat i sećanje na poslednji ustaški zločin u Sisku – masakr počinjen na obali Save 4. maja 1945. godine, uoči povlačenja ustaša iz grada. Iako su žrtve masakra, u lokalnom kontekstu poznatije kao “savske žrtve”, postale vidljivi objekat javnog sećanja u Sisku nakon rata, do sada nije objavljen nijedan istraživački rad o samom događaju, a memorijalizacija je bila praćena i upečatljivim nedostatkom zainteresovanosti za identitete žrtava, kao i za činjenice o tome kako su nastradale. Ovaj članak predstavlja pokušaj da se, prvi put, odgovori na ključna pitanja o tome ko su bile žrtve, koliko ih je bilo i zbog čega su stradale, time se opirući dugotrajnoj tradiciji izbegavanja odgovara na ta pitanja ili negiranja tih događaja. Istraživanje masakra u Sisku je važno i zbog toga što su još od sedamdesetih godina 20. veka prisutne spekulacije da tela pronađena na obali Save ne pripadaju žrtvama ustaškog masakra, već žrtvama partizanskih osvetničkih ubistava počinjenih nakon oslobođenja Siska. Ta revizionistička interpretacija je dobila na snazi u Hrvatskoj od devedesetih godina prošlog veka, pa su čak i neki hrvatski “mejnstrim” istoričari sugerisali da, usled nedostataka istorijskih dokaza o samom zločinu, tvrdnje revizionista ne smeju biti momentalno odbačene. Rad kritički preispituje tu tvrdnju, ukazujući na činjenice u vezi s tim događajem, u želji da pruži preko potrebna objašnjenja. Takođe, mapiranjem događaja u Sisku tokom poslednjih nedelja rata, ovaj članak nastoji da pokaže kako masakr na obali Save u Sisku nije bio izolovan slučaj. Postojali su i drugi zločini počinjeni u Sisku i okolini u poslednjim nedeljama rata, koji su u velikoj meri deo priče o savskim žrtvama, ali koji su do sada bili potpuno nepoznati. Među njima je i jedan od poslednjih masakra Srba koje su počinile ustaše, kao i verovatno i poslednji akt Holokausta u Nezavisnoj Državi Hrvatskoj. Ovaj članak nastoji da osvetli te ranije nepoznate događaje i da otkrije identitet stradalih žrtava.

ANALYSIS OF TIMBERCRETE: SAWDUST-INFUSED CONCRETE MIXTURES
Authors: Fasasi M. O.
Published: May 2024

This investigation aims to advance sustainable construction practices by investigating the feasibility and environmental benefits of incorporating sawdust instead of sand in concrete mixtures. By using sawdust, a byproduct of the forestry industry, in the process of making concrete, the investigation addresses the pressing need for resource conservation and waste reduction, since the construction sector is a significant user of raw materials. According to British European Norm Standard BS 8500-2:2023 for C35 grade concrete, the experimental programme examines how different percentages of sawdust (0%, 5%, 10%, 15%, 20%, and 25%) substituted for sand affect the physical characteristics of concrete, including its compressive strength, dry density, and water absorption. The workability, consistency, and strength of the sawdust-incorporated concrete mixes were assessed by a combination of techniques including sieve analysis, slump testing, casting and curing procedures, and compression tests. The results indicate a potential reduction in material costs and environmental impact with the ideal sawdust content by showing a negative association between the amount of sawdust and the concrete's density and compressive strength. A larger sawdust content was associated with higher rates of water absorption, highlighting the hygroscopic nature of sawdust and its implications for the durability of concrete. According to the investigation's results, it is possible to substitute concrete with up to 5% sawdust, providing an environmentally friendly alternative to conventional concrete while still having sufficient mechanical properties for use in construction. It is recommended that further research be conducted to improve sawdust's compatibility with cementitious materials, increase the durability of sawdust-incorporated concrete, and create industry guidelines for its use. This investigation contributes to the body of knowledge on environmentally friendly building materials by promoting the use of sawdust and other eco-friendly substitutes in the building sector to reduce negative effects on the environment and increase resource efficiency.

Published: May 2024

Como en todo gremio disciplinario, el lenguaje juega un papel fundamental para poder definir y realizar los procesos requeridos. Para aquellos que nos hemos desenvuelto dentro de la disciplina del grabado es sencillo entender la jerga de la disciplina; sin embargo, ¿qué pasa con aquel que entra por primera vez a un taller o con aquel autodidacta que quiere aprender sin la guía de un maestro? El presente glosario no es un diccionario que defina cual enciclopedia cada acepción que posea una palabra: es una guía para aquellos que se interesan por el grabado y quieren desenvolverse dentro de un taller de impresión, por lo que solamente se aborda el significado aplicado en las técnicas del grabado. Con el objetivo de lograr que la jerga utilizada dentro de un taller sea entendible para todos, “El ABC del grabado: Glosario de términos utilizados dentro de los talleres de producción gráfica”, como el título lo indica, es una compilación de términos tanto de técnicas como de materiales y herramientas utilizados dentro de la disciplina del grabado. Asimismo, debido a que la venta de materiales y herramienta especializada, así como una buena cantidad de la bibliografía sobre esta noble disciplina, se desarrollan dentro de la lengua inglesa, el glosario incluye el término que se describe también en este idioma, para que el usuario pueda buscar herramienta, libros y videos sin dificultad alguna.

Published: May 2024

Ameloblastoma is well recognized as a locally invasive benign neoplasm thought to arise from the cellular components of the enamel organ. Broca described ameloblastoma in 1868 [1]. Ameloblastoma contributes to about 1 % of all head and neck tumors and 13 to 58% of all odontogenic tumors [2]. Maxillary ameloblastoma is rare and account for 15% of all ameloblastomas. Slow-growing, painless swelling of the mandible or maxilla is the most common presentation of ameloblastoma and the diagnosis requires imaging (CT scan). Mutations in genes that belong to the mitogen-activated protien kinase MAPK pathway are found in many ameloblastomas, the most common being the BRAFV600E mutation [3].
