Since taxes are the foundation of an economy, efficient tax system is essential to its continued existence. Revenue generation depends on effective taxation, which measured by system's elasticity and buoyancy. Using data from 1991 2023, buoyancy a few South Asian Association for Regional Cooperation (SAARC) countries—Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, Sri Lanka—are examined in this work. The estimation coefficients has been done using pool least square approach. Gross...

Adipose-derived mesenchymal stem cells (ADMSCs) are considered an efficient and important candidate for male infertility treatment because they contain pluripotent cells, which can differentiate into all from three germ layers. However, the generation of germ-like cell (MGLCs) is one key issues, little known about mechanisms underlying MGLCs. Herein, we attempt to improve MGLCs derived during co-culturing rat ADMSCs with SCs under retinoic acid (RA) testosterone (T) treatment. isolated SD...

The transesterification of edible and non-edible oils to produce biodiesel is traditionally carried out using homogeneous catalysts (such as NaOH, KOH, H2SO4). However, these homogenous often suffer from multiple drawbacks including their corrosive nature solubility in the reaction mixture, high costs associated with recovery. Recent studies have shown that heterogeneous based on mixed metal oxides potential address issues conventional catalysts, thereby emerging an efficient class catalyst...
