A mathematical model is developed to analyze electro-kinetic effects on unsteady peristaltic transport of blood in cylindrical vessels of finite length. The Newtonian viscous model is adopted. The analysis is restricted under Debye–Hückel linearization (i.e., wall zeta potential [Formula: see text] 25[Formula: see text]mV) is sufficiently small). The transformed, nondimensional conservation equations are derived via lubrication theory and long wavelength and the resulting linearized boundary value problem is solved exactly. The case of a thin electric double layer (i.e., where only slip electro-osmotic velocity considered) is retrieved as a particular case of the present model. The response in pumping characteristics (axial velocity, pressure gradient or difference, volumetric flow rate, local wall shear stress) to the influence of electro-osmotic effect (inverse Debye length) and Helmholtz–Smoluchowski velocity is elaborated in detail. Visualization of trapping phenomenon is also included and the bolus dynamics evolution with electro-kinetic effects examined. A comparative study of train wave propagation and single wave propagation is presented under the effects of thickness of EDL and external electric field. The study is relevant to electrophoresis in haemotology, electrohydrodynamic therapy and biomimetic electro-osmotic pumps.

Coulombic repulsion alone is insufficient to mitigate aggregation of suspensions with strong charge screening, while superior interparticle separations are created via steric hindrance when dispersant layer thickness exceeds the Debye length.

This research article focuses on the theme of violence and its representation by the characters of the novel “This Savage Song” by Victoria Schwab. How violence is transmitted through genes to next generations and to what extent socio- psycho factors are involved in it, has also been discussed. Similarly, in what manner violent events and deeds by the parents affect the psychology of children and how it inculcates aggressive behaviour in their minds has been studied. What role is played by the parents in grooming the personality of children and ultimately their decisions to choose the right or wrong way has been argued. In the light of the theory of Judith Harris, this research paper highlights all the phenomena involved: How the social hierarchy controls the behaviour. In addition, the aggressive approach of the people in their lives has been analyzed in the light of the study of second theorist Thomas W Blume. As the novel is a unique representation of supernatural characters, the monsters, which are the products of some cruel deeds, this research paper brings out different dimensions of human sufferings with respect to these supernatural beings. Moreover, the researcher also discusses that, in what manner the curse of violence creates an inevitable vicious cycle of cruel monsters that makes the life of the characters turbulent and miserable.

Hospitals are the major contributor to environmental corruption and the biggest drain onenergy in their life cycle because they are complex, multifunctional giant facilities. Several recent studieshave been carried out to find the most suitable solutions to reduce energy consumption provide it on-siteand contribute to supporting economic, environmental and social aspects. The reason for the slowmovement of green buildings for hospitals is to focus on a suitable design for the complex function thatdeals with the local climate, natural resources, economy and cultural values and avoid the one-size-fits alldesign. This made the solutions used multiple and varied, different for greening of the hospital and put theresearch in the absence of a clear perception of the mechanisms of the application of green architecture inhospitals and this identified the problem of research. Therefore, the study looked at an analytical study ofexisting project models designed according to the strategies and standards of green architecture todetermine the strategies adopted in each project, and by adopting the analytical method after determiningthe strategy used in each building to achieve the green architecture and then comparing them according tothe standards adopted using the global LEED system Green Building Council. The results that will bereached are the mechanisms of applying Green Architecture to Hospitals.
