This work investigates the obliquely propagating wave solutions of conformable time fractional (2 + 1)-dimensional extended Zakharov–Kuzetsov equation (eZKE) for understanding the behavior of physical issues in science and engineering, especially in magnetized plasmas. The generalized exp(− Φ(ξ))-expansion method along with the conformable fractional derivatives is employed to obtain various types of exact solutions to eZKE. The traveling wave solutions of eZKE are represented in the forms of hyperbolic, trigonometric and rational functions with physical as well as some additional free parameters. It is found that the obliqueness and physical parameters are significantly modified the wave dynamics taking the appropriate values of free and physical parameters.

Early-life conditions influence organ growth patterns and their functions, as well as subsequent risk for non-communicable chronic diseases in later life. A limited number of studies have determined that in Bangladesh, kidney size relates to its function among children as a consequence of the maternal and postnatalconditions. The present study objectives were to determine early-life conditions in relation to childhood kidney size and to compare their influences on kidney function. The study was embedded in a population-based prospective cohort of 1067 full-term singleton live births followed from fetal life onward. Kidney volume was measured by ultrasound in children at the age of 4.5 years (range 45–64 months), and the estimated glomerular filtration rate (eGFR) was assessed at the age of 9 years (range 96–116 months). The mean (s.d.) kidney volume of children at 4.5 years was 64.2 (11.3) cm3, with a significant mean difference observed between low birth weight and normal birth weight children (P<0.001). The multivariable model showed, changes in status from low birth weight to normal birth weight children, with kidney volume increases of 2.92 cm3/m2, after adjusting for the child’s age, sex, maternal age and early pregnancy body mass index, and socio-economic index variables. One-unit change in kidney volume (cm3/m2) improved the eGFR to 0.18 ml/min/1.73 m2. The eGFR in low birth weight children was 5.44 ml/min/1.73 m2less than that in normal birth weight children after adjustments. Low birth weight leads to adverse effects on kidney size and function in children.

This work concerned with the oblique traveling wave solutions of coupled space-time fractional (2 + 1)-dimensional dispersive long wave equations (DLWE) for understanding the basic features of resonance wave dynamics in science and engineering, mainly in water wave dynamics. The generalized exp(− Ψ(ζ))-expansion scheme mutually by means of conformable derivatives is implemented to seek several types of faithful solutions of coupled DLWE. The oblique traveling wave solutions are displayed in the forms of trigonometric, hyperbolic and rational functions through physical and some supplementary free parameters. It is predicted that the obliqueness is significantly modified the oppositely propagating long waves assuming the suitable values of the parameters.

Language is vital to human beings, as it is a means of expressing thoughts, emotions and feelings. Impairments in the nervous system significantly affect the individual's language and behavior, bringing burdens on the family and the state. Stroke is the most common cause of language impairment, causing disorders due to specific brain injuries. We identified these disorders in the initial phase and intervened with speech therapy. Although the language problem in post-stroke patients is significant, this domain is poorly addressed in Bangladesh, which makes this work a pioneer. Large-scale studies are needed to better visualize the extent of the problem.
