Published: January 2025

ABSTRACT

Reducing water leakage in water supply networks has become the primary concern of water distribution companies. Challenges faced by developing countries suffering from increased water losses are mostly due to aging infrastructure. Pipes represent a large percentage of network assets; replacement with new good quality pipes reduces leakage, but represents major economic and implementation obstacles. Reducing leakage by reducing pressure in the network increased the challenge of supplying water adequately to consumers. We aimed to reduce leakage throughout the water distribution network using software to maximize benefits of pressure management in the water distribution network. The water distribution network of West Esna, Luxor, Egypt was simulated using WaterGEMS software and its Darwin Calibrator tools used to calibrate the network and estimate water leakage, depending on field pressure and flow measurements at selected points in the network. District metered areas were used as a tool to identify feeding flows in pipes to install pressure reducing valves. This study proves that pressure management significantly reduces water network leakage; simulated results show that leakage percent reduced from 33 to 23% with controlling pumping station pressure. Adding pressure reducing valves at boundary pipes contributed to leakage reduction in the entire network to 17%.

Utwory audiowizualne, bez względu na cele, dla których zostały wytworzone, służą transmisji jakiejś wartości informacyjnej Dotyczy to także audiowizualnych artefaktów, co oznacza, że można i należy traktować je jednocześnie jako przedmioty kulturowe (niekiedy także dzieła sztuki) oraz jako media (narzędzia przekazu informacji) i przekazy, wypełnione zawartością informacyjną, które zostały wytworzone po to, aby dotrzeć do jakiegoś odbiorcy – adresata tegoż przekazu (komunikacyjny punkt widzenia). W niniejszym tekście konstruuję teoretyczne podstawy dla analitycznego badania możliwości komunikowania wartości poprzez filmy. Autorski koncept oparty jest na połączeniu perspektywy komunikacyjnej i estetycznej poprzez komunikacyjną teorię filmu Calvina Prylucka. Zakładam, że zawartość informacyjna przekazu kulturowego, w tym ta o charakterze aksjologicznym, wyłania się z dwustopniowej analizy znaczeń tegoż utworu, tj. z analizy na poziomie kształtowania znaczenia i konstruowania znaczenia.
Idea sejfityzmu w kulturze współczesnej i jej egzemplifikacje w polskich portalach internetowych
Authors: Rusanowska Ida 
Published: January 2025

W artykule podjęty został temat sejfityzmu, a więc (coraz silniej obecnego we współczesnej kulturze) kultu bezpieczeństwa i związanej z tym tendencji do nadmiernego eliminowania wszelkich (prawdziwych i wyimaginowanych) zagrożeń dotyczących ludzkiego życia i zdrowia. Problematykę tę zawęziłam do dziedziny życia społecznego, jaką jest wychowanie dzieci i młodzieży. W tym kontekście sejfityzm przejawia się zwłaszcza w nadopiekuńczości rodziców, czyli w ich skłonności do przesadnego dbania o bezpieczeństwo dzieci, co w praktyce prowadzi do nieustannej kontroli nad poczynaniami dziecka (syndrom „helikopterowego rodzicielstwa”). W efekcie wychowujemy dziś istoty słabe, „kruche” psychicznie, nadwrażliwe na krytykę i stres. Refleksja nad kulturą sejfityzmu jest w Polsce nowa i nie doczekała się jeszcze syntetycznych opracowań, dlatego pierwsza cześć prezentowanego tekstu przedstawia przegląd (przed wszystkim zachodniej) literatury dotyczącej tego problemu. W artykule podkreślono również, że znaczącą rolę w procesie społecznego przyswajania sejfityzmu odgrywają media, zarówno społecznościowe, jak i tradycyjne - dlatego głównym celem pracy było zbadanie, czy idea ta jest już obecna w polskim dyskursie medialnym dotyczącym wychowania dzieci i młodzieży - a jeśli tak, to jak jest ona w nich prezentowana. Badania wykazały, że w polskich portalach internetowych poświęconych tematyce wychowawczej można odnaleźć przejawy kultury sejfityzmu w obu rozpoznanych przez teoretyków nurtach: wychowania w bezpieczeństwie fizycznym i emocjonalnym. Zaprezentowana w tej pracy analiza ma wartość poznawczą jako badanie eksploracyjne i umożliwia wstępną identyfikację problemu z perspektywy badań kulturowych, społecznych i medioznawczych. W zakończeniu artykułu zasygnalizowana została potrzeba pogłębionych badań nad obecnością idei sejfityzmu w mediach i jej wpływu na polskie społeczeństwo.

Background:
Plasma osteoprotegerin (OPG) has been linked to poor prognosis following
stroke, but its impact on post-stroke cognitive impairment (PSCI) is unknown. The purpose
of our work was to analyze the relationship of OPG with PSCI.

Methods:
Our study included 613 ischemic stroke subjects with plasma OPG levels. We used
the Mini-mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) to
assess PSCI. PSCI was defined as MMSE score <25 or MoCA score <23.

Results:
As assessed by the MMSE score, the adjusted odds ratio for PSCI in the highest OPG
tertile was 1.77, with a 95% confidence interval of 1.09 to 2.89 (Ptrend=0.021), compared to that
in the lowest tertile. We observed a positive linear relationship of plasma OPG levels with 3-
month PSCI (P for linearity=0.046). Incorporating plasma OPG into conventional risk factors
enhanced PSCI risk reclassification (all P <0.05). Consistent results were discovered when PSCI
was evaluated using the MoCA score.

Conclusion:
High plasma OPG levels were related to an elevated risk of 3-month PSCI, indicating
that OPG might be an effective biomarker for predicting PSCI.

Published: January 2025

Web servers have become crucial to facilitate access to and distribute such content on the internet. In this case, Docker containerization technology offers a solution. Docker allows developers to package applications and dependencies in one container, making deploying web servers faster and easier. But with these features, is there any performance that must be sacrificed if we choose to use docker in our web server deployment process. We will look at how much performance will be sacrificed. However, we must thoroughly analyze how Apache2 performs when running in a Docker container compared to running natively. That's why we're conducting a study to compare the performance of Apache2 in a Docker container versus a native environment using experimental methods. For this study, we'll use the Apache bench tool to test Apache2's performance in both environments. By experimenting, it should become clear how the performance of Docker containers compares to native environments when developing web servers. The research shows that Apache2 performance on native hosts is about 5-10% better than in a docker environment in handling small request loads. The better performance here refers to the parameters we tested: total time results, requests per second, and transfer speed. The request load variation can differ depending on the server specification itself. Although Docker offers features in terms of application isolation and scalability, our results show that running Apache2 natively is more efficient without changing its default configuration. The additional overhead Docker can be required to run the docker system in isolating the application; in this case, the virtualization layer is required to run Apache2 inside a Docker container. This can affect application performance and cause a slight performance degradation compared to using the host operating system directly. This research aims to inform developers about the performance difference between apache2 in Docker and the native environment. It will help them make informed decisions about deployment environments. Docker offers appealing features, but its performance may need to improve. Test results show that the native host performs better, although its feature set is not as extensive as that of Docker.

Published: January 2025

Hepatitis B is a viral infection that primarily targets the liver, potentially causing acute or chronic liver diseases with severe complications, such as cirrhosis and liver cancer. Its persistent prevalence underscores its status as a noteworthy global health issue. In this research, we construct a mathematical model for the progression of hepatitis B through fractional derivative, accounting for a two-dose vaccine regimen. The basic results and concepts of the Caputo-Fabrizio (CF) derivative has been presented for the analysis of the model. We investigate the infection-free equilibrium of the model and determine the endemic indicator of the system with the help of next-generation matrix method, indicated by $\mathcal{R}_0$. We demonstrate that the infection-free equilibrium of the model exhibits local asymptotic stability when $\mathcal{R}_0 <1$, and instability in all other scenarios. We establish conditions ensuring the existence and uniqueness of solutions for the proposed fractional dynamics model of hepatitis B. In addition to this, we present a new numerical method for analyzing the time series analysis of the system. Through our investigation, we elucidate the impact of input variables on the dynamic behavior of the system and identify the critical factors within the model. Our analysis identifies key parameters of the model that can be targeted for the control and management of hepatitis B infection.

The analysis of dynamic stability is a fundamental and an important concept in systemdynamics. Its focus is on the ability of a dynamical system to return to an equilibrium stateunder structured perturbations. The study of dynamic stability plays critical role in various fields,for instance, engineering, control theory, and economics. The analysis on the dynamic stability mostly involves computation of the eigenvalues of a system’s state matrix. The D-stability is a particular and specialized form of dynamic stability, and its mainly focus dynamical systems subject to structured perturbations. In this paper, we present new results on dynamic stability, and D-stability of a class of linear economic model in the mathematical form
$$y_t = Ay_t + By_{t-1} + Cx_t,$$
with $y_t$ is a vector of the endogenous variables, xt is a vector of exogenous variables, and A, B, and C are the matrices having an appropriate dimensions. The new results are developed on both necessary and sufficient conditions on the interconnection between D-stable matrices and structured singular values. The numerical experimentation show the behaviour of structured singular values for matrices appearing across linear dynamic model.
