    Opis:
    By modifying Ghahramany’s integrated nuclear binding energy formula with strong and weak interaction features, it is possible to approximate nuclear binding energy of isotopes with one unique energy coefficient and four terms. Considering even-odd corrections, shell corrections and other microscopic corrections, it seems possible to improve the accuracy. Based on our recent work and the proposed formulae, we are very confident to say that, quark structure helps in increasing nuclear binding energy and electroweak interaction helps in reducing nuclear binding energy.

    Opis:
    In this paper, the influence of heat transfer on the peristaltic flow of a conducting Phan-Thien-Tanner fluid in an asymmetric channel with porous medium is studied. The coupled nonlinear governing differential equations are solved by a perturbation technique. The expressions for the temperature field, the stream function, the axial velocity, and the pressure gradient are obtained. The effects of the various physical parameters such as the magnetic parameter M, the permeability parameter σ, the Brinkman number Br and the Weissenberg number We on the pumping phenomenon are analyzed through graphs and the results are discussed in detail. It is observed that the velocity and the pressure are decreased with increasing the magnetic parameter M whereas the effect of the parameter M on the temperature field is quite the opposite.

    Opis:
    By modifying the basic definition of cosmic red shift as [z/(1+z)], considering ‘speed of light’ as an absolute cosmic expansion rate, adopting ‘Planck mass’ as the basic seed of the observed large scale universe and following a scaled form of Hawking’s black hole temperature formula, it is certainly possible to review and revise the basic picture of ‘standard cosmology’ and in near future, a perfect model of ‘white hole cosmology’ can be developed. In this context we have developed five assumptions. Independent of matter density fractions, first assumption is helpful in understanding galactic red shifts and galactic light travel distances. Second and third assumptions are based on ‘time reversed’ black holes and seem to be well connected with General theory of relativity as well as Quantum mechanics. Fourth and fifth assumptions are helpful in understanding current galactic dark matter and flat rotation speeds. It may be noted that, considering our first three assumptions and considering the Planck Legacy 2018 data’s enhanced lensing amplitude in cosmic microwave background power spectra - conceptually, a closed universe having a positive curvature seems to be a best fit for the observed universe. With reference to our recent publication [26], for clarity on the subject, in this paper, we make an attempt to review and explain our proposed assumptions at fundamental level. Our aim is to see that, professional and non-professional cosmologists must understand the basics of workable quantum cosmology
