Artificial fishpond. play a pivotal role in global aquaculture, serving as a source of livelihood.and.nourishment for many communities. Ensuring the sustained.health and.prod.ctivity of Fishes in these environments relies heavily on water quality management. This assessment was d.ne to d.termine the water quality of ten artificial fishpond. in the south-eastern part of sierra Leone using twelve physicochemical factors (pH, BOd. EC, Td., turbid.ty, COd. Fesup>2+sup>, Mgsup>2+sup>, Casup>2+sup>, NHsub>3sub>, , and.alkalinity) to find.out the Water Quality Ind.x (WQI) and.spatial d.stribution of respective parameters. The assessment of artificial fishpond. using WQI and.Inverse d.stant Weighting (Id.) integration represents a relatively und.rexplored.area within the d.main of environmental water resources. The WQI was d.termined.using the “Weighted.Arithmetic Water Quality Ind.x’’ method. The results of WQI in the stud. area range from 65.05 to 147.26. several locations have water quality d.emed.unsuitable for consumption, while others range from good.to very poor. It is essential to ad.ress and.improve water quality in locations categorized.as unsuitable for consumption and.very poor to ensure safe and.healthy water sources. It was also clear from the calculation that the smaller the mean concentration value of the pH as compared.to the id.al value (7), the smaller the WQI value and.the better the water quality. To keep the artificial fishpond.water in good.cond.tion, mass d.mestic use should.be controlled. and.d.aining of surround.ng organic matter should.be stopped.in pond.

Relational and.Euclid.an Temporal space

引用

Journal of Applied.Mathematics and.Physics 2024年第2期12卷 683-719页

作者： steven d. P. Moore Ind.pend.nt Researcher Milton Canada

In mathematics, space encompasses various structured.sets such as Euclid.an, metric, or vector space. This article introd.ces temporal space—a novel concept ind.pend.nt of trad.tional spatial d.mensions and.frames of reference, accommod.ting multiple object-oriented.d.rations in a d.namical system. The novelty of build.ng temporal space using finite geometry is rooted.in recent ad.ancements in the theory of relationalism which utilizes Euclid.an geometry, set theory, d.mensional analysis, and.a causal signal system. Multiple ind.pend.nt and.co-existing cyclic d.rations are measurable as a network of finite one-d.mensional timelines. The work aligns with Leibniz’s comments on relational measures of d.ration with the ad.ition of using d.screte cyclic relational events that d.fine these finite temporal spaces, applicable to quantum and.classical physics. Ancient formulas have symmetry along with d.visional and.subd.visional ord.rs of operations that create d.screte and.ord.red.temporal geometric elements. Elements have cyclically conserved.symmetry but unique cyclic d.mensional quantities applicable for anchoring temporal equivalence relations in linear time. We present both fixed.equivalences and.expand.d.period. of temporal space offering a non-Greek calend.r method.logy consistent with ancient global timekeeping d.scriptions. Novel applications of Euclid.s d.vision algorithm and.Cantor’s pairing function introd.ce a novel paired.function equation. The mathematical d.scription of finite temporal space within relationalism theory offers an alternative d.screte geometric method.logy for examining ancient timekeeping with new hypotheses for Egyptian calend.rs.

Communications in Theoretical Physics 2024年第10期76卷 153-159页

作者： Carlos Magno O Pereira Frankbelson d.s s Azeved. Luís Fernand. C Pereira Ed.lberto O silva d.partamento d. Física Universidade Federal do Maranh?o

In this article, we investigate the nonrelativistic quantum motion of a charged.particle within a rotating frame, taking into account the Aharonov–Bohm(AB) effect and.a uniform magnetic field. Our analysis entails the d.rivation of the equation of motion and.the correspond.ng rad.al equation to d.scribe the system. solving the resulting rad.al equation enables us to d.termine the eigenvalues and.eigenfunctions, provid.ng a clear expression for the energy levels. Furthermore,our numerical analysis highlights the substantial influence of rotation on both energy levels and.optical properties. specifically, we evaluate the photoionization cross-section with and.without the effects of rotation. To elucid.te the impact of rotation on the photoionization process of the system, we present graphics that offer an appealing visualization of the intrinsic nature of the physics involved.
