Οι μαθητές Ε' τάξης Δημοτικού στο τρέχον πρόγραμμα σπουδών διδάσκονται καταστάσεις της ύλης και αλλαγή κατάστασης σε μακροσκοπικό επίπεδο και τα ερμηνεύουν με ένα στοιχειώδες σωματιδιακό μοντέλο. Στο τέλος των μαθημάτων σε γραπτή δοκιμασία περιγράφουν τις διαστάσεις του σωματιδιακού μοντέλου και τη διάκριση διαφορετικών ουσιών. Αν και αναπαράγουν τις διαστάσεις του σωματιδιακού μοντέλου, δεν είναι σε θέση να εκτιμήσουν τι κάνει διαφορετικά τα μόρια των διαφορετικών ουσιών και υποθέτουν ότι τα μόρια έχουν την ίδια ύλη σαν την ουσία που σχηματίζουν και οι διαφορές οφείλονται στον τρόπο σύνδεσης ή στα φυσικά χαρακτηριστικά των μορίων.

Η παρούσα διδακτική πρόταση βασίστηκε στο Νέο ΠΣ του Νηπιαγωγείου κι επικεντρώνεται στη διδασκαλία των φυσικών εννοιών που αφορούν στο καιρικό φαινόμενο της καταιγίδας σε παιδιά προσχολικής ηλικίας. Υλοποιήθηκε σε τρία νηπιαγωγεία και αξιοποιήθηκε διδακτικά το μοντέλο 5E.Βασικοί στόχοι ήταν η κατανόηση της αστραπής και του κεραυνού, η ανάπτυξη δεξιοτήτων συνεργατικής εργασίας και δημιουργικής έκφρασης, και η αναγνώριση της αξία της ψηφιακής πληροφορίας.Σύμφωνα με προηγούμενες έρευνες, τα παιδιά προσχολικής ηλικίας έχουν εναλλακτικές αντιλήψεις για το φαινόμενο της καταιγίδας. Τα αποτελέσματα έδειξαν ότι οι αρχικές τους αντιλήψεις, που ήταν θεοκρατικές ή βασίζονταν στις αισθητηριακές τους εμπειρίες, αντικαταστάθηκαν με μια πιο επιστημονική κατανόηση. Τα παιδιά έδειξαν ενδιαφέρον για τις δραστηριότητες και συμμετείχαν ενεργά σε αυτές. Η χρήση του διδακτικού μοντέλου 5E, καθώς και των ψηφιακών τεχνολογιών, υποστήριξε την ενεργή εμπλοκή των παιδιών στη μαθησιακή διαδικασία και την πληρέστερη κατανόηση των φυσικών φαινομένων.
PyRates—A code-generation tool for modeling dynamical systems in biology and beyond
Authors: Gast Richard , Knösche Thomas R. , Kennedy Ann 
Published: December 2023

The mathematical study of real-world dynamical systems relies on models composed of differential equations. Numerical methods for solving and analyzing differential equation systems are essential when complex biological problems have to be studied, such as the spreading of a virus, the evolution of competing species in an ecosystem, or the dynamics of neurons in the brain.
Here we present PyRates, a Python-based software for modeling and analyzing differential equation systems via numerical methods. PyRates is specifically designed to account for the inherent complexity of biological systems. It provides a new language for defining models that mirrors the modular organization of real-world dynamical systems and thus simplifies the implementation of complex networks of interacting dynamic entities. Furthermore, PyRates provides extensive support for the various forms of interaction delays that can be observed in biological systems.
The core of PyRates is a versatile code-generation system that translates user-defined models into “backend” implementations in various languages, including Python, Fortran, Matlab, and Julia. This allows users to apply a wide range of analysis methods for dynamical systems, eliminating the need for manual translation between code bases.
PyRates may also be used as a model definition interface for the creation of custom dynamical systems tools. To demonstrate this, we developed two extensions of PyRates for common analyses of dynamic models of biological systems: PyCoBi for bifurcation analysis and RectiPy for parameter fitting. We demonstrate in a series of example models how PyRates can be used in combination with PyCoBi and RectiPy for model analysis and fitting. Together, these tools offer a versatile framework for applying computational modeling and numerical analysis methods to dynamical systems in biology and beyond.

Authors: AlRashed Hamad , Miele Johanna , Prasad Joshua , Adenikinju Deborah , Iloegbu Chukwuemeka , Patena John , Vieira Dorice , Gyamfi Joyce , Peprah Emmanuel 
Published: December 2023

Aim and objectives
The aim of this study was to conduct a systematic review analysis to identify and evaluate the available literature on implementation science outcomes research in relation to End Stage Renal Disease (ESRD) in Pakistan.

Methods
A systematic database search of PubMed, Web of Science, EMBASE, Cochrane Library, CINAHL, and Ovid was conducted through October 22nd, 2022, without any restrictions on publication dates. A screening and data extraction tool, Covidence, was used to evaluate the literature against our inclusion and exclusion criteria. Furthermore, a Mixed Methods Appraisal Tool (MMAT) was used to evaluate the selected studies.

Results
We identified four studies that presented findings of implementation outcomes research which were related to appropriateness, feasibility, and acceptability. Appropriateness was examined using knowledge scores (p = 0.022) and medication adherence scores (p < 0.05) that showed statistical significance between the control and intervention groups. Acceptability was assessed through a cross sectional quantitative descriptive study that evaluated the reasons for refusal and acceptance of treatment in a cohort of patients suffering from ESRD. Feasibility was examined in one cross sectional, and one mixed methods study that aimed to evaluate and understand the impact of initiating dialysis treatment and the feasibility of maintaining it in low-income families that care for children or adults with ESRD.

Conclusion
The preliminary results of this review indicate a gap in the availability of implementation research studies about ESRD in Pakistan. The burden of ESRD, and the implementation methods by which it is treated is notable in Pakistan and requires evidence-based measures to be implemented to support the critical healthcare delivery platforms that provide treatment.

A swirl in the river of becoming: some thoughts about Walter Benjamin’s concept of origin
Abstract: This article aims to present some considerations about the concept of origin (Ursprung) for Walter Benjamin's conception of history, based on an image, described by the philosopher in the text “Diary from August 7, 1931, to the day of my death”. With this article I intend to accomplish two things: first of all, I wish to demonstrate that the category of origin is, in Benjamin, the cornerstone upon which his conception of history is built; furthermore, I intend to search for tools that may help to understand the way in which a historical analysis is made possible when grounded upon the concept of origin, by focusing on specific meanings therein concerning that category.

Law and Economics of Language Model Development: Empirical Examination of Corporate Strategies and Vaporware Claims
Authors: Arai Koki 
Published: December 2023

Abstract
This research investigates the application of corporate strategies in developing Large Language Models (LLMs) like ChatGPT, with a focus on law and economic aspects. Improved LLM performance is largely credited to expanded dataset size, leading to developments of similar models in non-English languages. This study questions whether such announcements, particularly in the Japanese market, could be classified as ‘vaporware’ posing potential antitrust issues. Using a stock event approach, the research scrutinizes the possibility of vaporware characteristics in these announcements by examining any resultant cumulative abnormal returns (CARs). The empirical evidence suggests an absence of significant upsurges in CARs in response to these announcements, implying a lack of vaporware characteristics and a stable market response. Consequently, in a market displaying reasonable efficiency towards investment in LLM development, these findings underscore the necessity for meticulous contemplation of competition policy regulation and the implementation of industrial policy promotion measures.

High concentration of sepsis-associated aromatic microbial metabolites (AMM) stands as a prognostically unfavorable factor, indicating the progression of multiple organ dysfunction and an increased risk of death in patients with sepsis and septic shock. This study is based on a hypothesis that excess of sepsis-associated AMM in patients with sepsis is caused by metabolic alterations (dysfunction) in the intestinal microbiota.The aim of this study was to compare the potential of normobiota and pathobiota to bio-transform sepsis-associated metabolites of aromatic amino acids tyrosine and phenylalanine, such as phenyllactic acid(PhLA) and 4-hydroxyphenyllactic acid (4-HPhLA).Materials and methods. Samples of intestinal contents of patients with septic shock (N=10, pathobiota) and healthy volunteers (N=9, normobiota) were placed in test tubes with the omnipurpose thioglycol medium. The clinical model of excessive inflow of sepsis-associated AMM into the intestine (for example, from blood or sites of inflammation) was reproduced in the in vitro experiment by adding PhLA or 4-HPhLA in clinically significant concentrations (25 mkM) into each test tube with pathobiota and normobiota. After incubation in a thermostat (37°, 24 hours), AMМ concentrations were measured in the samples with pathobiota and normobiota using GC-MS analysis.Results. Concentration of AMM decreased within 24 hours in the tubes with normobiota after PhLA or 4-HPhLA were added. In the tubes with pathobiota, no decrease in AMM concentrations was documented after loading with PhLA or 4-HPhLA. Concentrations of PhLA (P=0.002) and 4-HPhLA (P0.001) were statistically significantly higher in pathobiota samples compared to normobiota.Conclusion. The in vitro experiment demonstrates that after excessive load with sepsis-associated metabolites (PhLA, 4-HPhLA), the microbiota of healthy people is capable to bio-transform such metabolites to the end products of microbial metabolism, while pathobiota of septic patients exhibits altered biotransformational potential. This data demonstrate that microbiota dysfunction may contribute to the pathogenesis of sepsis.
Identification of the influence of electrokinetic soil improvement on the microstructure, physical and mechanical properties of expansive soil

Published: December 2023

Clay is a soil with low permeability. Clay is considered a problematic soil besides peat soil. The main problem with clay is its mineralogy. Expansive clay soils contain the minerals kaolinite, illite, and montmorillonite. Montmorillonite has weak bonds between its layers. These weak bonds make the soil easily incorporated, one of which is water. Water approaching expansive soil will bond with it and cause swelling.
Expansive soil improvement studies have been conducted. One of them is electrokinetic. Expansive soil from Karawang, Indonesia is one of the soils with a high swelling index. This is because montmorillonite is inside. The Karawang expansive soil will be improved by flowing several salt solutions with various voltages. The applied voltage will flow the solution from the cathode to the anode and fill the clay minerals. Four voltage variants will be applied with the same electrokinetic application time.
The mineralogy of soil before and after electrokinetic improvement undergone changes. The changes can be seen from SEM and XRF testing. The improved soil changed its physical properties from clay with high plasticity to clay with low plasticity. Chemical elements from salt solution trap in montmorillonite then make positive changes in soil mineralogy, soil physical properties, and mechanical properties. The mechanical properties can be seen in a decrease in the C value and an increase in the soil angle of friction after electrokinetic improvement. After electrokinetic improvement using calcium chloride, the lowest soil cohesion value was 12.356 kg/cm2 at 12 V. After electrokinetic improvement with calcium dioxide, the lowest cohesion value at 12 V voltage is 19.22 kg/cm2. In barium sulfate solution, the lowest soil cohesion at 15 V is 12.16 kg/cm2. The soil swelling value decreased after improvement with calcium chloride to 0.008 % from 0.027 %. The research results in calcium chloride with 12 V give optimized results on soil improvement with electrokinetics

Published: December 2023

The object of research is the seed material and working bodies of a vibro-pneumatic centrifugal separator; the subject is their interaction. The established surfaces, which are the results of the simulation of the process of separation of seed materials in the vibro-pneumatic centrifugal separator, have a curve to the plane whose parameters are the speed of the air flow and the frequency of oscillations of the working surface. It is noted that this nature of the dependence of the purity of the «heavy» fraction of seeds on parameters of the separation process makes it possible to determine the rational ranges of these parameters, at which the maximum value of this characteristic is reached. Experimental simulation of the separation process in the vibro-pneumatic centrifugal separator of wheat, sunflower, and soybean seed materials under production conditions showed a high convergence of the results with the results of the simulation of the process under the same initial conditions. It was established that the correlation coefficients between the points obtained experimentally and obtained by simulation for the given results are in the range from 0.89 to 0.95. At the same time, the differences are the purity values of the «heavy» seed fraction, and not in the nature of its change due to changes in the parameters of the separation process. The expediency of using modeling when determining the rational values of the parameters of the separation process in the vibro-pneumatic centrifugal separator is noted. This will help increase the energy and resource efficiency of the equipment due to the absence of the need for experimental setup. The rational ranges of air flow speed and vibration frequency of the rotor of the vibro-pneumatic centrifugal separator for the separation of seed materials have been determined: wheat – 1.2...1.5 m/s; 4500...5100 cycles per minute; sunflower – 1.3...1.5 m/s; 4500...5000 cycles per minute; soybeans – 1.3...1.6 m/s; 5000...5500 cycles per minute

Published: December 2023

This article provides information on the identification of micromycetes found in samples taken from areas of transboundary rivers of Azerbaijan with different levels of anthropogenic impact, and the study of their role in the removal of pollutants. Certain micromycetes were used as indicators of water quality. As a result of the studies, micromycetes belonging to 38 species from 16 genera were identified.
Directly at the sampling site, water temperature, pH, and the amount of dissolved oxygen in the water were measured, and biogenic elements were determined in laboratory conditions. The presence of nutrients in the studied river waters showed variable results. Thus, in the Astarachay River, nitrites range from 0.01–0.02 mg/l, nitrates 0.56–0.70 mg/l, ammonium 0.5–1.50 mg/l, phosphates 0.00–0.01 mg/l. In the Bolgarchay River, these indicators for nitrite range from 0.02–0.05 mg/l, for nitrates 0.20–0.50 mg/l, for ammonium 0.10–0.44 mg/l, for phosphates 0.01–0.05 mg/l. In the Arazchay River, nitrites range from 0.01–0.83 mg/l, nitrates 0.08–7.40 mg/l, ammonium 0.05–3.57 mg/l, phosphates 0.05–0.94 mg/l, and in Okhchuchay these indicators for nitrite range from 0.09 to 0.71 mg/l. l, nitrates 0.68–6.00 mg/l, ammonium 0.23–6.45 mg/l, phosphates 0.09–0.65 mg/l.
The results obtained showed that the identified microscopic fungi are involved in the formation of rich flora as an adaptation in river waters. The biomass and number of micromycetes significantly depend on hydrochemical conditions: parameters such as temperature, dissolved oxygen, pH, forms of nitrogen, phosphorus and organic carbon fractions. It can be recommended to use mushrooms for biological control of surface water purity and sanitary safety. It should be noted that environmental factors also influence the diversity of micromycetes

Published: December 2023

In modern schools, we often encounter the problem that students lose interest in learning. Tasks of practical content are designed to increase interest in school mathematics education.
The orientation of the research of problems of practical content involves the orientation of methods in the process of solving problems and the formation of strong skills of independent activity in schoolchildren and the education of persistent interest in the subject. Also, practical tasks help to highlight interdisciplinary connections, make you delve deeper into theoretical aspects, and form a complete picture. In the process of solving such problems, students develop cognitive, informational and social competence. Learning becomes useful and, at the same time, exciting and interesting for students.
Word problems in the school mathematics course play a very important role and are divided by functions, by the requirements of the task, by types. The article is devoted to the analysis of the theoretical and methodological foundations of problems of practical content and their solution.
The purpose of the work is the classification of text problems according to various parameters based on the analysis of scientific and methodological literature on this topic. Word problems of such types as movement problems, work problems, buying and selling problems, interest problems, mixtures and alloys are selected for consideration. The main results of the publication include recommendations for creating a mathematical model of the problem condition using tables, depending on its type.
Problems of various types are presented, which are solved by constructing a corresponding mathematical model of the problem condition. This approach to studying the topic "Word problems" is used in my own experience of teaching mathematics
