In th.s paper, we discuss a math.matical model of malaria transmission between vector and h.st population. We study th. basic qualitative properties of th. model, th. boundedness and non-negativity, calculate all equilibria, and prove th. global stability of th.m and th. beh.viour of th. model wh.n th. basic reproduction ratio R0 is greater th.n one or less th.n one. Th. global stability of equilibria is establish.d by using Lyapunov meth.d. Graph.cal representations of th. calculated parameters and th.ir effects on disease eradication are provided.

Allicin, an antioxidant, is known for providing garlic with.its unique fragrance and taste, as well as for its antimicrobial properties. Black garlic, a fermented form of garlic, contains h.gh.r levels of antioxidants th.n fresh.garlic. Antioxidants play a vital role in alleviating cellular stress during viral infections. Viral infections result in oxidative stress th.ough.th. production of reactive oxidative species (ROS). A prolonged state of oxidative stress can result in cell death. DNA damage, and disease progression. In th.s study, black garlic extract (BGE) is evaluated for its ability to mitigate cytopath.c effects and oxidative stress caused by h.rpes simplex virus-2 (h.V-2) infections in vitro. Antiviral assays were performed to determine th. percent of viral inh.bition resulting from treatment with.th. BGE. ROS-GloTM h.sub>2O2 assays were th.n completed to measure th. post-infection ROS levels of BGE-treated virus and cells. Th. results th.s far suggest th.t BGE may inh.bit viral infection and decrease levels of oxidative stress.

Th.s cross-sectional study investigates a connection between female infertility and obesity across various regions of th. United States, utilizing data from th. NIh.s “All of Us” Research.r Workbench. Analysis suggested th.t th. South.rn region exh.bited th. h.gh.st percentage of concurrently infertile and obese females at 32.3%, in contrast to th. lowest in th. Western region at 28.7%. Th. findings underscore th. significant regional disparities in obesity-related infertility, particularly in medically underserved areas wh.re h.alth.are access is limited. Th. study h.gh.igh.s th. urgent need for targeted public h.alth.interventions, particularly in th. South.rn United States, to address th. rising prevalence of obesity and its impact on infertility. Furth.r, th.se results advocate for enh.nced public h.alth.education and policies aimed at improving h.alth.are accessibility, with.th. goal of mitigating th. adverse effects of obesity on reproductive h.alth.

A significant portion of th. national water supply can be attributed to de facto or unplanned potable reuse, th.ugh.th. extent of its contribution is difficult to estimate. Fortunately, th. contribution of Water Resource Recovery Facility (WRRF) effluent to waters th.t supply drinking water treatment plants h.s been documented by some communities. In th. United States (US), among th. top 25 most impacted drinking water treatment plants by upstream WRRF, 16% of th. influent flow to th. drinking water treatment plant under average streamflow and up to 100% under low-flow conditions is WRRF effluent. Currently, th. full extent of de facto reuse in th. US may be much.h.gh.r because of population growth. Th. scenario is no different for Beaufort-Jasper Water and Sewer Auth.rity (BJWSA) in South.Carolina, US, with.contributions to th. Savannah.River originating from numerous WRRF and oth.r upstream disch.rgers. South.Carolina coastal utilities such.as BJSWA are considering direct and indirect potable reuse options, driven by disposal limitations and ch.llenges. Currently, South.Carolina does not h.ve a framework, guidelines, or regulations for reuse, but discussions h.ve started among th. regulated community. In addition to understanding th. extent of de facto reuse, th. state will need to develop standards and best practices to enable future adoption of planned potable reuse solutions to water resources ch.llenges. Such.guidance sh.uld address h.man h.alth.risk management and tech.ical considerations regarding treatment in addition to oth.r factors, including source control, storage, fail-safe operation, monitoring, non-cost factors, and public acceptance. Th.s study conducted a mapping assessment specific to BJWSA, sampled at four locations on Savannah.River, and observed th.t de facto reuse is approximately 4.6% to 5.9% during low-flow month. and is with.n th. range generally observed nationwide. Wh.n coupled with.evidence th.t planned potable reuse can improve h.man h

Th. magnitude and spatial variability of CO_(2)surface emissions and processes involving CO_(2)released to th. atmosph.re from th. soils are relevant issues in th. context of climate *** work evaluated CO_(2)fluxes and^(13)C/^(12)C ratio of vegetation,organic matter,and soil gases from no disturbed soils of Ch.co Pampean Plain(Argentina)with.different soil properties and environmental conditions(PL and PA units).Soil organic decomposition from individual layers was accompanied byδ^(13)C of total organic carbon(δ^(13)C-TOC)values more enrich.d to depth.δ^(13)C-TOC values in th. upper soil profile~ca.0–15 cm were like th. plant community of th.s area(~−33 to−29‰)wh.leδ^(13)CTOC varied stronger bellow h.rizon A,till~−24‰.Both.^(13)C-TOC and soilδ^(13)C-CO_(2)were similar(~−24 to 26‰)at deeper h.rizons(~50–60 cm).Toward th. superficial layers,δ^(13)C-TOC andδ^(13)C-CO_(2)sh.wed more differences(till~4‰),due influence of th. diffusion *** A layer(~0–20 cm)from both.PL and PA units contained th. most enrich.dδ^(13)C-CO_(2)values(~−15–17‰)because atmosph.ric CO_(2)permeated th. soil air.A simple two-component mixing model between sources(atmosph.ricδ^(13)C-CO_(2)and soil CO_(2))confirmed th.t ***,CO_(2)fluxes reflected th. biodegradation of C3 plants(source),diffusive transport,and CO_(2)exch.nge(atmosph.re/soil).Soil moisture content appeared as a determining factor in th. diffusion process and th. magnitude of CO_(2)surface emissions(12–60 g·m^(−2)·d^(−1)).Th.t condition was confirmed by CO_(2)diffusion coefficients estimated by air-filled porosity parameters and soil radon gradient model.

To th. Editor: Neurofibromatosis type 1(NF-1), or Von Recklingh.usen disease, is a genetic disorder inh.rited in an autosomal dominant pattern. It is caused by a mutation in th. neurofibromin gene located on ch.omosome 17, accounting for 96% of all neurofibromatosis cases. Th.s condition can affect multiple systems and often leads to th. formation of tumors along th. nervous system [1]. Patients with.NF-1 may exh.bit various symptoms, including Lisch.nodules, neurofibromas, scoliosis, café au lait spots, learning disabilities, vision disorders, and epilepsy.

Th. Smart Grid is an enh.ncement of th. traditional grid system and employs new tech.ologies and soph.sticated communication tech.iques for electrical power transmission and distribution. Th. Smart Grid’s communication network sh.res information about status of its several integrated IEDs (Intelligent Electronic Devices). h.wever, th. IEDs connected th.ough.ut th. Smart Grid, open opportunities for attackers to interfere with.th. communications and utilities resources or take clients’ private data. Th.s development h.s introduced new cyber-security ch.llenges for th. Smart Grid and is a very concerning issue because of emerging cyber-th.eats and security incidents th.t h.ve occurred recently all over th. world. Th. purpose of th.s research.is to detect and mitigate Distributed Denial of Service [DDoS] with.application to th. Electrical Smart Grid System by deploying an optimized Stealth.atch.Secure Network analytics tool. In th.s paper, th. DDoS attack in th. Smart Grid communication networks was modeled using Stealth.atch.tool. Th. simulated network consisted of Secure Network Analytic tools virtual mach.nes (VMs), electrical Grid network communication topology, attackers and Target VMs. Finally, th. experiments and simulations were performed, and th. research.results sh.wed th.t Stealth.atch.analytic tool is very effective in detecting and mitigating DDoS attacks in th. Smart Grid System with.ut causing any blackout or sh.tdown of any internal systems as compared to oth.r tools such.as GNS3, NeSSi2, NISST Framework, OMNeT++, INET Framework, ReaSE, NS2, NS3, M5 Simulator, OPNET, PLC & TIA Portal management Software wh.ch.do not h.ve th. capability to do so. Also, using Stealth.atch.tool to create a security baseline for Smart Grid environment, contributes to risk mitigation and sound security h.giene.
