Abstract: PAA/polyaniline/MWCNT nanocomposite is successfully synthesised using aniline as monomer and MWCNT as additive by chemical oxidation method. The composite is characterized by XRD, FTIR, and UV-Visible, FESEM with EDS, HRTEM, DC conductivity and magnetoresistance. DC conductivity of aforementioned nanocomposites is determined by linear four-probe technique and the Highest DC conductivity of PAA/PANI/MWCNT (0.3 wt%) nanocomposites is found to be 0.0325 S/cm. Temperature dependent DC conductivity signifies semiconducting nature. Magnetoresistance of PAA/PANI/MWCNT (0.3 wt%) nanocomposite with different temperatures is studied and is non-linearly related to magnetic field.

Keywords: Acrylic Acid, Polyaniline, MWCNT, Composite, FESEM, HRTEM, Electrical Conductivity, and Magnetoresistance.

Abstract: People’s lives have been affected socially by the coronavirus around the globe. Because of its social and economic impact, some measures for the prevention of the disease have been placed so that the spread can reduce. Quarantine, social distancing, and social distancing are some of the control measures. One that is considered to be very effective is for the vulnerable population to be isolated. A Model including six compartments was developed so that the number of people recovering may increase, so to achieve this vulnerable population was isolated. These six compartments are namely below; Susceptible, Exposed, Infected, Quarantined, Isolation of Vulnerable, and Recovered. Formulation of endemic equilibrium points, disease-free equilibrium, and local stability of disease-free equilibrium were theoretically proved. By use of the next generation matrix, derivation of basic reproductive number which is abbreviated as Rₒ was done. There is THE stability of disease-free equilibrium which is also abbreviated as a disease-free equilibrium when the basic reproductive number is less than one, which is R0<1 . There is the stability of endemic equilibrium, the endemic equilibrium point when the basic reproductive number is greater than one, which is R0>1 . There is instability in disease-free equilibrium when R0>1 . Susceptible, Exposed, Infected, Isolated Vulnerable and Recovered population model was solved numerically by Runge Kutta 4th order; the drawn graphs also showed that when the vulnerable population is isolated there is an increment in the number of people who recover and a reduction in deaths. More isolation Centers so as to isolate vulnerable populations to recover more is recommended whereby the world health organization and ministry of health in Kenya need to put it in place.

Keywords: Isolation Infected, Coronavirus, Vulnerable, Pandemic, Quarantine, Susceptible, Exposed; and Recovery.

Abstract: A worldwide pandemic called COVID-19 has afflicted humanity in various aspects of life. There exists, several mathematical models aimed at limiting the transference of COVID-19.This research brings in, the intervention of RT-PCR screening of international travelers seeking to identify the infected at the beginning phases of infection, to lower the rate of its spread led by high mobility of human beings, therefore, the novelty is on RT-PCR screening as a control measure. We create and examine a SPEIR model for COVID 19 dynamics incorporating RT-PCR screening and apply the results to explore COVID-19 dynamics in the presence of screening of international travelers. The model includes five time dependent compartments Susceptible(S), Screened(P), Exposed(E), Infected(I) and Recovered (R).We developed the basic reproduction number (R₀) and investigated the existence of all the equilibrium points; the disease free equilibrium and endemic equilibrium and determined their  stabilities. The epidemic model’s system of differential equations was subjected to numerical simulations by use of Matlab. The interpretation and comparison to the qualitative solutions was done and the outcome after the analysis is that RT-PCR screening revealed a clear picture of the evolution and spread of COVID-19,with its infections having fallen off significantly. This study shows that RT-PCR screening of travelers is paramount in preventing the spread of COVID-19.

Keywords: COVID-19 spread dynamics, mathematical modelling, epidemiological modelling, RT-PCR screening modelling.

Abstract: This paper gives another representation of general fractional exponential function and fractional logarithmic function. In addition, we discuss some properties of them based on Jumarie type of Riemann-Liouville (R-L) fractional calculus. These properties are the same as those of classical exponential function and logarithmic function. The main methods used in this paper are the chain rule for fractional derivatives and a new multiplication of fractional analytic functions.

Abstract: Quinoline is a hygroscopic liquid that is colorless has a pungent odor and Darkens with age. It is soluble in alcohol, ether, benzene, and carbon disulfide and is sparingly soluble in water. Quinoline is a weak tertiary base. It forms salts in acids and exhibits reactions similar to benzene and pyridine, and can engage in both electrophilic and nucleophilic substitution (HSDB), Quinoline, also known as 1-azanaphthalene, 1-benzazine, or benzo[b]pyridine, is a heterocyclic aromatic organic compound. It has the formula C₉H₇N.  Quinoline structure is known ever since 1908 and proved by total synthesis by Wood ward and Doe ring in 1945. It was the structural model for other anti-malarial quinoline derivatives. It was first isolated by Runge in 1834 from coal tar bases and subsequently, Coal tar remains as the principle source of commercial quinoline; If its aged sample is exposed to light, it turns became yellow and later brown.

Keywords: QuinoLine, Pharmaceutical, Heterocyclic.

Abstract: The importance and versatility of derivatives of quinolines is well established in many forms of drugs, potential use of lanthanide complexes as diagnostic molecule have also been reported in literature but studies on biological aspects of complexes of lanthanides related with bioactive species are lesser.  The constructions and characterizations of lanthanide complexes are currently of great interest because of their unique physico-chemical properties and various applications in medical field. The present work describes the synthesis, spectral and biological investigations on the complexes of quinoline derivatives with Gd (III) ions in agreement to Green chemistry approach. The magnetic moment of Gd (III) complexes showed slightly higher-values which originated due to low J-J separation leading to thermal population of next higher energy J levels and susceptibility due to first order Zeeman Effect. For various peaks of Gd (III) Intensity (Judd Oflet T₂, T₄, T₆ and oscillator strength P_obs×10⁶⁾, Bonding b^1/2, Symmetry (T₄/T₆₎ and Cordination (T₄/T₂) RMS deviation σ parameters have been computed using partial and multiple regression methods. In this research investigations on micellar doped Gd(III) systems have been reported first time. Antimicrobial activities of compounds have also been determined.

Keywords: Quinoline, Gd (III), Antimicrobial activity, bonding parameters.
