Authors: Süzük Erol , Çorlu Mehmet Ali , Gürel Cem
Published: July 2024

The aim of this study was by using students’ self-assessments to identify the learning efficiency of introductory (mechanics and waves) physics course connecting physics to students’ everyday life. Physics is one of the most difficult courses for students, mainly because its presentation is theoretical, mathematical and abstract without everyday applications and examples. Moreover, connections to students’ everyday life are crucial for learner’s mental construction of the information they learn and for achieving meaningful learning. The findings of this study are significant in evaluating the learning efficiency of the physics course, which was presented by connection to students’ everyday life. The sample consisted of a total of 92 first year undergraduates, 82 of which were male and 10 were female. Data was collected by a likert type scale which was prepared in line with the post-then-pre test method called “Students’ Perceptions of Learning – Students’ Self-Assessment” developed by the Author. Hake’s formula was used in order to calculate learning efficiency. The findings of this study indicated that learning efficiencies were high for the areas in which students were interested in everyday life. Moreover, that learning efficiencies were higher for topics students had learnt before in comparison to new ones. Mean that learning efficiency of the lesson was calculated as 0.5, which was between 0.3 and 0.7, and thus indicated moderate learning efficiency.

Rich Environments for Active Learning and Science Learning in Nigeria
Authors: Jacob Babatunde Peter
Published: July 2024

Science is part of human live and actions, despite its importance; there is crisis in learning science. Some of this problem can be traced to the emphasis of learning basic facts and definitions from text books as against the applications of knowledge in daily life or the development of higher order thinking. To implement a successful science education in Nigeria, there is need to help students transfer learning from one situation to another. Learners must be helped to see themselves as constructors of knowledge in a variety of forms; learning must be seen as a collaborative process; learners should be assisted to bring their own needs and experiences to a learning situation; they should be helped to acquire skills and knowledge within realistic contexts; and methods used for assessment must take more realistic and holistic forms. In order to meet the developmental challenges of Nigeria and developmental economies, science learning should be encouraged using REALS which have been shown to enhance the effective learning.
Improving liability measures for crimes involving the illegal handling of narcotic drugs, psychotropic substances, and their analogues
Authors: Otajonov Abrorjon ,   Tashkent State University of Law
Published: July 2024

The article discusses the problems of law enforcement practice in crimes of illicit trafficking in narcotic drugs, psychotropic substances, and their analogues, reveals the features of public danger, the need for implementation of international documents, as well as prospects for improving liability for this type of crime. Based on the results of the study, existing gaps and contradictions were identified in the regulation of criminal legislation providing for liability for crimes of illicit trafficking in narcotic drugs or psychotropic substances. In particular, the composition of the crimes provided for in Chapter XIX of the Criminal Code is of a blank nature, but these norms contradict the norms of the Law of the Republic of Uzbekistan «On Narcotic Drugs and Psychotropic Substances», which determines their content, as well as the complexity of the structure of the norms defining responsibility for this type of crime. Some norms establish responsibility for various types of crimes, and in the practice of applying the law, mistakes are made when applying most of the signs aggravating responsibility for these types of crimes. In addition, the criminal law does not establish criminal liability for certain socially dangerous acts, and some requirements of international legal documents in the field of drug control are not implemented in national legislation. At the same time, these situations lead to inefficiency in combating crimes of illicit trafficking in narcotic drugs or psychotropic substances and to uneven application of this type of criminal law in practice. Based on this, the article puts forward proposals and recommendations aimed at improving the effectiveness of combating crimes of illicit trafficking in narcotic drugs or psychotropic substances and eliminating the identified problems and shortcomings.

Authors: Egamberdiev Eduard ,   Tashkent State University of Law, Shaimardanova Dilafruz ,   Tashkent State University of Law
Published: July 2024

The article analyzes the legal problems of the realization of the last will of the testator in respect of digital objects. The objects of the will can be various results of intellectual activity in digital form: accounts in social networks and messengers, photos and videos in cloud storage, text documents, music, e-books, and other files. The article discusses in detail the reasons for the difficulties in determining the legal nature of digital objects as objects of inheritance. It notes the lack of common definitions and the heterogeneity of approaches to the interpretation of digital rights in different legal systems. The article analyzes the insufficient level of understanding of the technological aspects of the functioning of digital objects among lawyers and legislators, which hinders the formation of a mechanism for effective legal regulation. The objective factors that currently limit the possibilities for the implementation of the last will of the testator when transferring digital assets by inheritance are analyzed in detail. Such factors include the imperfection of the traditional form of will in relation to virtual objects and various technical and legal restrictions on access for heirs. Based on the generalization of foreign experience and the experience of the Republic of Uzbekistan, specific directions for improving the legal regulation of the process of inheritance of digital rights are outlined, including the development of international standards, the creation of specialized forms of digital wills, and improving the digital literacy of citizens and lawyers

в работе представлен метод подготовки данных и последующая визуализация решения задачи Коши, которая возникает при моделировании динамики примеси в потенциальных течениях, а также при моделировании динамики примеси в вязкой несжимаемой жидкости в цилиндрической области течения. Задача Коши решалась с использованием метода Рунге–Кутты 4-го порядка точности. Разработано программное обеспечение для решения задачи Коши в трехмерном пространстве, которое в автоматическом режиме визуализирует полученные результаты. Такая постановка задачи может применяться для моделирования динамики течения безынерционной недиффундирующей примеси, растворенной в жидкости, в случае, когда векторное поле V , являющееся решением задачи Коши, удовлетворяет уравнениям гидродинамики. Задача Коши рассматривается на целом множестве начальных данных, задающем поле распределения примеси в начальный момент времени. Разработанное программное обеспечение позволяет проводить вычисления с распределением по доступным ядрам ЭВМ на основе технологии OpenMP. В качестве средства визуализации использовалась библиотека MathGL. Представлены результаты тестирования программного обеспечения.

this paper presents a method for data preparation and visualization of the solution to the Cauchy problem, which arises in simulating the dynamics of impurities in potential flows and in a viscous incompressible liquid within a cylindrical flow region. The Cauchy problem was solved using the 4th-order Runge-Kutta method. We developed software that solves the Cauchy problem in 3D space and automatically visualizes the results. This method can simulate the dynamics of an inertialess, non-diffusing impurity in a liquid, provided that the vector field V , which solves the Cauchy problem, satisfies the hydrodynamics equations. The problem is considered for the entire set of initial data defining the impurity distribution at the initial time. The software performs calculations distributed over available computer cores using OpenMP. The MathGL library was employed for visualization. The paper also presents the results of software testing.

Crossbreeding parameters for body weight data from a complete diallel mating scheme using three breeds of rabbit
Authors: Abdel-Ghany Ahmed M. , El-Mansy Salah A. , Alshaya Dalal S. , Al Aboud Nora M. , Gharib Mahmoud G.
Published: July 2024

Abstract. The objective of this study was to evaluate heterosis, general combining ability (GCA), maternal ability (GM), and sex-linked effects (SL) for growth performance from weaning (at 4 weeks) up to marketing age (at 12 weeks) using a complete 3×3 diallel crossing experiment in three different breeds of rabbit: one native Egyptian (Baladi Red, RR) and two exotic (Bauscat, BB, and Californian, CC). Offspring (2617 rabbits) body weight data (BW; 4–12 weeks of age) were analyzed, mainly to evaluate the effects of mating groups (MGs), sex, year season, and parity. MGs were further analyzed for crossbreeding parameters. All crossbreds showed positive, highly significant values (P≤0.001). Heterosis (HI; overall or specific) for body weight at all evaluated ages was highly significant (P≤0.001). Purebred differences were affected significantly (P≤0.01 or P≤0.001). No significant effects were detected due to general combining ability, maternal abilities, or reciprocal effect (sex-linked). Results suggest that to some extent and because of the highly purebred significant differences (P≤0.01 or P≤0.001), those three breeds are expected to be too genetically far apart to make crosses showing significant heterosis. Since other crossbreeding effects are non-significant, heterosis is the only reliable effect that can produce the Egyptian broiler rabbits when using those three breeds. However, the insignificance of the reciprocal impact (sex-linked as a whole or, by definition, the additive effects of genes carried on the sex chromosomes) of the two acclimatized standard breeds (CC and BB) seemed to be of magnitude at least to the 10th week of age.
Wind comparisons between meteor radar and Doppler shifts in airglow emissions using field-widened Michelson interferometers
Authors: Kristoffersen Samuel K. , Ward William E. , Meek Chris E.
Published: July 2024

Abstract. Upper-atmosphere winds from a meteor radar and a field-widened Michelson interferometer, co-located at the Polar Environment Atmospheric Research Laboratory in Eureka, Nunavut, Canada (80° N, 86° W) are compared. The two instruments implement different wind-measuring techniques at similar heights and have very different temporal and spatial observational footprints. The meteor radar provides winds averaged over a ∼ 300 km horizontal area in 3 km vertical bins between 82 and 97 km on a 1 h cadence. The E-Region Wind Interferometer II (ERWIN) provides airglow-weighted winds (averaged over volumes of ∼ 8 km in height by ∼ 5 km radius) from three nightglow emissions (O(1S), oxygen green line, 557.7 nm, 97 km; an O2 line, 866 nm, 94 km; and an OH line, 843 nm, 87 km) on a ∼ 5 min cadence. ERWIN's higher precision (1–2 m s−1 for the O(1S) and OH emissions and ∼ 4 m s−1 for the O2 emissions) and higher cadence allows more substantive comparisons between winds measured by meteor radar and Doppler shifts in airglow emissions than previously possible for similar meteor radar/airglow Doppler shift comparisons using Fabry–Perot interferometers. The best correlation is achieved using Gaussian weighting of meteor radar winds with peak height and vertical width being optimally determined. Peak heights agree well with co-located SABER airglow observations. Offsets between the two instruments are ∼ 1–2 m s−1 for the O2 and O(1S) emissions and less than 0.3 m s−1 for the OH emission. Wind directions are highly correlated with a ∼ 1:1 correspondence. On average, meteor radar wind magnitudes are ∼ 40 % larger than those from ERWIN. Gravity wave airglow brightness weighting of observations is discussed. Non-quadrature phase offsets between the airglow weighting and gravity wave associated wind and temperature perturbations will result in enhanced or reduced layer-weighted wind amplitudes.

Published: July 2024

Abstract. Global change is known to exert a considerable impact on marine and coastal ecosystems, affecting various parameters such as sea surface temperature, rain-off, circulation patterns, and the availability of limiting nutrients like nitrogen, phosphorus and silicon, each influencing phytoplankton communities differently. This study is based on weekly to fortnightly in vivo phytoplankton observations in the French waters of the Eastern English Channel at fine spatial resolution (∼1 km) along an inshore-offshore gradient in the Strait of Dover. Phytoplankton functional composition was addressed by automated ‘pulse shape-recording’ flow cytometry, coupled with analysis of environmental variables over the last decade (2012–2022). This method allows for the characterization of almost the entire phytoplankton size range (from 0.1 μm to 800 μm width) and the determination of the abundance of functional groups based on optical single-cell signals (fluorescence and scatter). We explored seasonal, spatial, and decadal dynamics in an environment strongly influenced by tides and currents. Over the past 11 years, sea surface temperatures showed an increasing trend in all stations, with nearshore waters warming faster than offshore waters (+1.063 °C vs. +0.929 °C). Changes in nutrient concentrations have led to imbalances in nutrient ratios (N:P:Si) compared to Redfield molar reference ratios, though a rollback (2012–2018) to balanced ratios (since 2019). Phytoplankton total abundance has also increased over the decade, with a higher contribution of small-size cells (picoeukaryotes and picocyanobacteria) and a decrease in microphytoplankton, particularly near the coast. The winters of 2013–2014 and 2019–2020 have been identified as shifting periods in this time series. This study provides the first assessment of decadal changes of the whole phytoplankton community by an automated in vivo single-cell approach, which will need to be explored further in the frame of changes in trophic transfers and water quality.
Connecting stratospheric and tropospheric seasonal predictability
Authors: Portal Alice , Lee Simon H.
Published: July 2024

Seasonal prediction systems which contribute to the Copernicus Climate Change Service (C3S) multi-model suite are used operationally to forecast the state of the atmosphere a season ahead. During Northern Hemisphere winter, a source of potential seasonal forecast skill is the strength of the Arctic stratospheric polar vortex and its coupling to tropospheric modes of variability. The intraseasonal-to-seasonal variability in the vortex strength can induce shifts in the position and strength of the mid-latitude tropospheric jet, and an accurate representation of stratospheric variability in models has been shown to enhance tropospheric predictability at seasonal time scales. The strength of the Arctic vortex and the coupling between the stratosphere and the troposphere are commonly described by anomalies in the multi-level hemispheric atmospheric mode known as the North Annular Mode (NAM). In this work we investigate the relationship between NH stratospheric and tropospheric predictability during boreal winter from a systematic multi-model assessment of the vertical structure and skill of NAM. Overall, the ensemble-mean hindcasts from C3S models (1993/94 – 2016/17) show a poor performance in predicting the seasonal NAM across all atmospheric levels. The hindcasts display slightly higher prediction skill in the stratosphere than in the troposphere, consistent with its longer timescales, yet no clear pattern connecting stratospheric to tropospheric skill. A monthly-frequency analysis reveals a pronounced dip in the January tropospheric skill across all models and initialisation dates. Since this appears to be linked to a bias in the vertical troposphere-stratosphere NAM coupling during January, we investigate the origin of the models’ behaviour by looking into the vertical structures of large-scale mid-latitude planetary waves. The deterioration of the seasonal winter skill by the mid-winter model performance indicates a route towards improving seasonal forecasts of the NH winter troposphere. 
Characterization of extreme wave fields during Mediterranean tropical-like cyclones
Authors: Davison Silvio , Benetazzo Alvise , Barbariol Francesco , Ricchi Antonio , Ferretti Rossella
Published: July 2024

Mediterranean tropical-like cyclones (MTLC; Cavicchia et al., 2014) are mesoscale disturbances that manifest tropical-like characteristics, especially around the eye, with a morphology similar to tropical cyclones (TC; see Emanuel, 2005), without visible frontogenesis in the mature stage. In general, due to both the physical processes that intensify the cyclone and the region in which it develops, their ground structure varies considerably. Indeed, although tropical-like storms have also been observed in the Atlantic Ocean (Franklin et al., 2006) and Black Sea (Efimov et al., 2008), they occur predominantly in the Mediterranean Sea (and are therefore also known as Medicanes), particularly in the Ionian, the Balearic, and the Tyrrhenian sub-basins (see Patlakas et al., 2021), where the topography and coastal morphology play a key role in determining the near-surface wind fields and consequently the genesis and evolution of the wave fields, more frequently in late summer and autumn. Medicanes are rare compared to other cyclones (Cavicchia et al 2014) that occur in the Mediterranean Sea, since they originate in a baroclinic environment, albeit still requiring several atmospheric conditions to produce a barotropic environment, like warm core, spiraliforma clouds band, intense wind speed and well defined eye. The frequency of occurrence varies according to the type of MTLC considered: if only very strict criteria are adopted, ie only storms with fully tropical features (such as cloud structure, degree of symmetry, dimensions, and lifespan on satellite images), 0.5 events occur per year on average, while if hybrid structures are also included around 1.5 Medicanes per year occur (Cavicchia et al., 2014).
Evaluation framework for regional reanalyses at DWD: results and outlook
Authors: Spangehl Thomas , Borsche Michael , Niermann Deborah , Bär Franziska , Drücke Jaqueline , Kelbch Alexander , Kaspar Frank , Imbery Florian , Becker Andreas
Published: July 2024

The development and provision of regional reanalyses requires a coordinated quality assessment targeted to user needs. Regional reanalyses with higher temporal and spatial resolution are of particular importance for applications in the energy sector. Detailed information is required on meteorological parameters such as wind speed and direction at hub heights of modern wind turbines (offshore and onshore), global radiation and near-surface temperature. In addition, regional reanalyses are of interest for climate applications dealing with climate extremes such as strong wind, heat waves, heavy precipitation and droughts.The regional reanalysis COSMO-R6G2 is currently produced at DWD as a successor of COSMO-REA6. It is based on a newer version of the COSMO model and ERA5 boundary conditions, which enables continuous updating. The nudging technique (Newtonian relaxation) is used for the assimilation of conventional observations stemming from radiosondes, SYNOP stations, ships, buoys or aircrafts. No satellite data is assimilated.The quality is assessed using in-situ measurements of offshore FINO research platforms, tower and lidar measurements over Germany (companion paper by Bär et al., EMS 2024), DWD’s station network for Germany and satellite-based surface irradiance data of CM SAF as reference. Uncertainties are addressed by a comprehensive comparison to other state-of-the-art reanalyses and derived products.The temperature and radiation biases seen in COSMO-REA6 are still similarly present in COSMO-R6G2. However, there is evidence that the representation of reduced shortwave transmissivity related to the effect of optically thick clouds is more realistic in COSMO-R6G2 compared to COSMO-REA6 where post-processing methods have already been proven for bias adjustment of non-cloudy cases.
Enhancing Australia's Drought Resilience: Insights from the Australian Climate Service Hazard Teams
Authors: Hoffmann David , Parker Tess , Bhardwaj Jessica
Published: July 2024

Drought, as a recurrent phenomenon, exerts a profound impact on Australia's agricultural productivity, water resources, ecosystem health, and socio-economic stability, while also serving as a catalyst for heatwaves and severe fire seasons. Drought can manifest on varied timescales, leading to non-linear and complex impacts. Long-term droughts in Australia are often linked to large-scale climate modes including the El Niño-Southern Oscillation, the Indian Ocean Dipole, and the Southern Annular Mode. Contrary to the belief that drought is a slow onset hazard, drought conditions affecting agriculture can also develop rapidly in a matter of weeks under favourable synoptic conditions (flash drought) and may compound with heatwaves and high fire risk.  

The several types of drought and driving factors preclude a uniform definition and as a result many drought indices exist. However, most climate information portals offer only precipitation-based measures as a drought proxy, often neglecting important changes in temperature and evaporation, that do not sufficiently capture changes in drought intensity, frequency, and duration to support informed decision-making. Additionally, the rarity of drought events in historical observations, together with the high variability and uncertainties in the magnitude of precipitation change and the response of large-scale atmospheric circulations to global warming, challenge reliable future projections. 

The Australian Climate Service (ACS) has been formed to provide improved data, intelligence and expert advice on climate risks and impacts to support and inform decision-making. Recognising the significance of drought as well as current knowledge and service gaps, the ACS has recently established a dedicated Climate Hazard Team to comprehensively investigate drought and changing aridity across Australia under global warming. This team is one of ten covering natural hazards of importance at a national level in Australia – identified via the National Climate Risk Assessment. The hazard teams unite the ACS Partners CSIRO, Bureau of Meteorology, Geoscience Australia, and the Australian Bureau of Statistics, as well as other experts from across Australia, including those at universities. The team will provide actionable information for resilience and adaptation strategies using a suite of drought indices calculated from observational and downscaled climate model data, drawing on top-tier scientific knowledge from ACS and university partners to fill these gaps. 

This presentation will provide an overview of the Australian Climate Service, the drought hazard team in particular, drought research and services for Australia, and findings to support communities, emergency management and federal government in taking informed decisions.

Current context of climate change is impacting many sector’s activities: rising temperatures or the increased frequency of extreme events is affecting water or energy demands, or the way and schedule for crop growing. Climate services based on seasonal forecasts can provide a useful tool helping to adapt current practiques to a new scenario.However, and with the exception of certain “windows of opportunity”, skill of seasonal forecasts is in general limited within mid-latitudes, so the development of a service needs a careful selection of the sources of information, postprocessing and calibration. Here, we present two examples of services for water and agriculture sector making use of seasonal forecasts, both co-developed with users:The first one has been developed jointly with water authorities in Spain, providing probabilistic forecasts of both high resolution precipitation and inflow for the majority of Spanish reservoirs during the 5 month period spanning from November to March.The service makes use of different sources of information, including different runs from ECMWF-SEAS5 and empirical forecasts based on snow accumulation. The close relationship between accumulated winter precipitation and North Atlantic Oscillation over Iberia is used to calibrate and weight the ensemble based on a “Best NAO” hybrid forecast, improving the skill. Additionally, a downscaling methodology combining analogs and regression is applied, providing improved skill over a wider area.The information is then feeded in a web visor available through AEMET web, developed jointly with users. Every year, information for the upcoming winter and new version of the web application is presented, and discussion on results, usability and possible improvements take place, keeping the service updated to user needs.The second one provides crop yield forecasts for raind fed winter cereals (barley and wheat) over Castille and Leon. A vegetal model is run for every grid point every day of the season using observations. A particular day of the season, the model is coupled using medium range forecasts and then using both an ensemble based on climatology and ECMWF-SEAS5 downscaled forecasts, and results are compared. A set of synthetic observations, coupling vegetal model to ERA5, is produced and validated, in order to evaluate the performance. Information is then provided to users through the stakeholders in the region.

The real-time measurement of ionospheric (geometry-free) combinations, of transmitter-receiver Global Navigation Satellite Systems (GNSS) multifrequency carrier phase measurements, constitute the input of a unique all-time all-weather global detector of the distribution and changes of electron content in the Earth ionosphere (see for instance Hernández-Pajares et al. 2011).The resulting area of research, GNSS Ionosphere (see definition in Hernández-Pajares et al. 2022), and the corresponding Space Weather monitoring capabilities with unprecedented spatial and time resolution, will be summarized in this presentation. In particular, the performance of the real-time 24/7 detection and measurement of solar flares during more than one solar cycle (Hernández-Pajares et al. 2023) will be illustrated and commented. The system relies on continuous tracking of the intensity of expected global patterns in the Earth’s ionosphere’s free electron distribution, which are associated with solar ﬂares. A summary of the corresponding validation will be provided, comparing it to external and direct solar EUV ﬂux measurements obtained from space missions, like the SOHO-SEM. In particular we will show how GNSS Ionosphere can provide better solar flare detection and solar EUV flux rate tracking performance than such a conventional orbital EUV photometers, under events involving relativistic electrons.

Wind farm effects on weather forecast using HARMONIE-AROME

Published: July 2024

Wind farms affect the atmosphere due to blockage, wakes and speed-ups. These modifications also affect other meteorological variables such as temperature, humidity and clouds locally under certain meteorological conditions. Therefore, there is a need to include wind farm effects in weather forecasts both for good-quality power predictions, but also for improved weather forecast in general.To evaluate the influence of currently existing on- and offshore wind turbines in Europe, we perform forecasts with the operational NWP model HARMONIE-AROME. The HARMONIE-AROME model is equipped with two wind farm parameterizations (WFPs), namely the WFP by Fitch et al. (2012) implemented by van Stratum et al. (2022) and the Explicit Wake Parameterization (EWP) by Volker et al. (2015) implemented by Fischereit et al. (2024).To represent the existing wind turbines in the simulations, we assembled an European wind turbine database for existing on- and offshore turbines that contains turbine locations and turbine characteristics such as hub height, rotor diameter and thrust curves. For the database we combined seven different data sets with a machine learning gap-filling approach to fill missing information.Using the database, we simulate a winter and a summer month with both WFP and compare them to a control simulation without wind farms for central and northern Europe. The simulations indicate that wind speed, temperature and humidity are affected locally by the presence of wind turbines. The wind farm effects differ in magnitude and sometimes in sign for the two WFPs. Fischereit, J., Vedel, H., Theeuwes, N. E., Larsén, X. G., Giebel, G., & Kaas, E. (2024).

Published: July 2024

Flash floods are one of the most devastating natural hazards. Every year, they cost thousands of lives and millions of dollars in damaged infrastructure. They can occur in large or small catchments, rural or urban areas, close or away from rivers, and with little to no warning. Some regions might have adapted to protect infrastructure and people against this hazard; however, with climate projections suggesting that extreme rainfall might increase in intensity and frequency, "residual risk" might increase in protected areas while unprotected ones might experience unseen severe losses. Hence, relying on medium-range forecasts that offer good predictions of areas at risk of flash flooding with enough lead time to extend preparedness and action time windows is becoming increasingly important.This presentation will showcase the most recent developments in the prediction of flash floods over a continuous global domain up to medium-range lead times. We will start by describing the system (ecPoint) used to create the rainfall-based flash flood predictions (ecPoint-Rainfall forecasts) and the warning thresholds that identify areas at risk of flash floods (ERA5-ecPoint rainfall reanalysis). We will also present long-term objective verification results that benchmark our rainfall-based flash flood predictions against competing rainfall forecasts, e.g. ECMWF ensemble forecasts. Through the presentation of case studies, we will explore the added value of using our proposed forecasts in case of low-probability but high-impact flash flood events. We will finally provide practical guidance and recommendations on how to use the flash flood predictions to enable decision-makers to extend their preparedness and action time window.
