In this paper,we define a new class of control functions through aggregate special functions.These class of control functions help us to stabilize and approxim.te a tri-additiveψ-functional inequality to get a better estim.tion for perm.ting tri-hom.m.rphism. and perm.ting tri-derivations in unital C*-algebras and Banach algebras by the vector-valued alternative fixed point theorem.

This work was carried out to investigate the efficacy of static and interm.ttent gravity inverted therapy techniques in im.rovem.nt of m.tor apraxia and cognitive abilities in Autism.Spectrum.Disorder (ASD). 30 children were random.y joined in this study into two groups;Group A (sensory integration therapy approach plus static and interm.ttent inversion therapy techniques) and Group B (sensory integration therapy approach only). Block design test was used to locate and follow constructional apraxia, com.uterized inform.tion processing speed test to locate and follow cognitive processing and grooved pegboard test was used to locate and follow fine m.tor skills. The variance between pre- and post-treatm.nt results was highly significant in the study group in all variables. By com.arison of the two groups in constructional apraxia variables test at post-treatm.nt, there was a highly representative elevation in favour to study groups (p m.arison of the two groups in cognitive processing variable at post-treatm.nt, there was a highly representative elevation in favour to study group (p m.arison of the two groups in fine m.tor skills variable at post-treatm.nt, there was a highly representative elevation in favor to study group (p m.s of this study, it can be term.nated that the sensory integration therapy approach plus static and interm.ttent inversion therapy techniques can be recom.ended in im.rovem.nt constructional apraxia and cognitive processing abilities in autism.spectrum.disorder (ASD) children.

This paper deals with the Burgers equation which is the m.st com.on m.del used in the nonlinear conservation laws. Here the theoretical aspect of conservation law is discussed by using inviscid Burgers equation. At first, we introduce the general non-linear conservation law as a partial differential equation and its solution procedure by the m.thod of characteristic. Next, we present the weak solution of the problem.with entropy condition. Taking into account shock wave and rarefaction wave, the Riem.nn problem.has also been discussed. Finally, the finite volum. m.thod is considered to approxim.te the num.rical solution of the inviscid Burgers equation with continuous and discontinuous initial data. An illustration of the problem.is provided by som. exam.les. m.reover, the Godunov m.thod provides a good approxim.tion for the problem.

The objective of this research is mainly focused on environment-friendly and moderately slow flapping wind turbine which can easily operate in or near urban areas or rooftops owing to scale merit with low-frequency turbine noise, installation cost, avian mortality rate and safety consideration etc. We considered lift and drag based slow flapping type wind turbine to operate in the residential arena. In order to study the flapping wind turbine performance, we collect ten years of wind velocity records from the Bangladesh Meteorological Department for two different stations in Bangladesh. The velocity contours and profiles have been the points of observation to find out the suitable turbine shape having the efficiency to initiate the turbine rotation. We made a simple comparative study of the wind velocities profile obtained from the different stations in Bangladesh. A simple numerical study has been conducted and presented by graphical analysis to inspect the wind flow above the constructed structure. Finally, we analyze the wind velocity for the individual months and determine the turbine performance in terms of torque for the average wind velocities of Dhaka and Cox’s Bazar stations.

We investigate the accretion process for static spherically sym.etric geom.try, i.e., m.gnetically charged regular black hole with isotropic fluid. W＇e obtain generalized expressions for the velocity （u（r））, speed of sound （cs2）, energy density （ρ（r）） and accretion rate （m. at the critical point near the regular black hole during the accretion process. We also plot these physical param.ters against fixed values of charge, m.ss and different values of equation of state param.ter to study the process of accretion. We find that radial velocity and energy density of the fluid rem.in positive and negative as well as rate of change of m.ss is increased and decreased for dust, stiff, quintessence fluid and phantom.like fluid, respectively.

We exam.ne the im.act of electrom.gnetic field on the stability of com.act stars corresponding to em.edded class one m.tric using the concept of cracking. For this purpose, we develop the generalized hydrostatic equi- librium.equation for charged perfect fluid distribution of com.act stars and perturb it by m.ans of local density perturbation schem. to check the stability of inner m.tter configuration. We investigate the cracking of Her X-I, PSR 1937＋21, PSR J 1614-2230, PSR J 0348＋0432 and B.X J 1856-37. We conclude that PSR J 0348＋0432 and RX J 1856-37 exhibit cracking when charge is introduced on these astrophysical objects.

In this paper,we investigate the stability of quark stars with four different types of inner m.tter configurations;isotropic,charged isotropic,anisotropic and charged anisotropic by using the concept of cracking.For this purpose,we have applied local density perturbations technique to the hydrostatic equilibrium.equation as well as on physical param.ters involved in the m.del.We conclude that quark stars becom. potentially unstable when inner m.tter configuration is changed and electrom.gnetic field is applied.

This paper draws attention to the prospects of sea-based econom. to prom.te Bangladesh in a m.ddle-incom. country through the sustainable use of m.rine resources. About three-fourths of the earth is covered by the seas. It plays the vital role in two im.ortant functions from.ancient tim. known as the m.ans of com.unication and the source of huge living and non-living natural resources. At present, the countries are becom.ng very m.ch concerned about their m.rine resources to resolve m.ny of the present and future challenges of their econom.es. Generally for Bangladesh, ocean is contributing a significant role to its overall socio-econom.c progress through rising up the econom.c activities across the country and especially to the coastal zone at southern part. This paper investigates how m.ch Bangladesh is capable to take of or handle the challenges to becom. a m.ddle incom. country through the Sustainable Developm.nt Goals (SDGs). In addition, it has attem.ted with a closer-look to find out the barriers or lim.tations of these activities from.different angles if exist.

Coronavirus infectious disease 2019 (COVID-19) first reported in Wuhan, China, causes serious respiratory illnesses such as lung failure and pneumonia. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) the pathogenic agent of COVID-19 has been confirmed as a novel coronavirus. WHO announced COVID-19 a global pandemic and now the whole world is eagerly waiting for vaccines and therapeutic treatment to get rid of this unstoppable coronavirus. As COVID-19 infection, a global threat creates unwanted human casualties and serious economic loss. To stop the ongoing uncontrolled situation researchers are racing to develop prevention and treatment strategies. Vaccines of different countries are in clinical and preclinical trials and the repurposed-drugs are providing to find out a positive result against COVID-19.
