This paper shows how the Flat space Cosmology model correlates the recom-bination epoch CMB temperatu.e of 3000 K with a cosmological redshift of 1100. This proof is given in su.port of the recent pu.lication that the Tatu. and seshavatharam Hu.ble temperatu.e formu.ae can be derived u.ing the stephan-Boltzmann dispersion law. Thu., as explained herein, the era of high precision Planck scale qu.ntu. cosmology has arrived.

The nonlinear schr?dinger equ.tion equ.tion is one of the most important physical models u.ed in optical fiber theory to explain the transmission of an optical soliton. The field of chiral soliton propagation in nu.lear physics is very interesting becau.e of its nu.erou. applications in commu.ications and u.tra-fast signal rou.ing systems. The (1+1)-dimensional chiral dynamical stru.tu.e that describes the soliton behaviou. in data transmission is dealt with in this work u.ing a variety of in-depth analytical techniqu.s. This work has applications in particle physics, ionised science, nu.lear physics, optics, and other applied mathematical sciences. We are able to develop a variety of solu.ions.to demonstrate the behaviou. of solitary wave stru.tu.es, periodic soliton solu.ions, chiral soliton solu.ions, and bell-shaped soliton solu.ions with the u.e of applied techniqu.s. Moreover, in order to verify the scientific calcu.ations, the stability analysis for the observed solu.ions of the governing model is taken into consideration. In addition, the3-dimensional, contou., and 2-dimensional visu.ls are su.plied for a better u.derstanding of the behaviou. of the solu.ions. The employed strategies are dependable, u.complicated, and effective; yet have not been u.ilised with the governing model in the literatu.e that is now accessible. The resu.ting ou.comes have impressive applications across a large nu.ber of stu.y areas and compu.ational physics phenomena representing real-world scenarios. The methods applied in this model are not u.ilized on the given models in previou. literatu.e so we can say that these describe the novelty of the work.

Physicochemical parameters of su.face water sou.ces in the stu.y of local government areas (LGAs) were assessed u.ing standard procedu.es. The mean physicochemical parameters for pH (5.49), NO2 (0.23 mg/L), sO4 (0.77 mg/L), Na (28.72 mg/L), Ca (28.94 mg/L), Mg (17.50 mg/L), Cl (11.65 mg/L), Tss (6.27 mg/L), TDs (104.23 mg/L), BOD (2.83 mg/L) and F (0.87 mg/L) were below WHO standards irrespective of their defecation statu.. The valu.s for electrical condu.tivity (EC) (2770.50 µs/cm, tu.bidity (481.24 NTu., dissolved oxygen (DO) (5.32 mg/L), chemical oxygen demand (COD) (445.50 mg/L), K (125.06 mg/L), PO4 (0.78 mg/L) and Fe (0.57 mg/L) were above the WHO limits for safe water. Higher EC and COD valu.s obtained in the stu.y is evidence of pollu.ion of the water sou.ces by organic matter.
