In this paper, Eringen’s nonlocal elasticity and Timoshenko beam theories are implemented to analyze the bending vibration for non-uniform nano-beams.  The governing equations and the boundary conditions are derived using Hamilton’s principle. A Generalized Differential Quadrature Method (GDQM) is utilized for solving the governing equations of non-uniform Timoshenko nano-beam for pinned-pinned...

Small-scale dairy farming in Bangladesh is constrained mostly due to acute shortage, high price and seasonal fluctuation of energy and protein supplements. Poor economic conditions of dairy farmers do not allow them to purchase adequate conventional energy and protein supplements. Locally available non-conventional energy and protein sources can be used as alternatives, cheaper than conventiona...

The appropriate treatment of patients with stage IIIA (N2) nonsmall-cell lung cancer (NSCLC) is unclear. With this case report and review, we address the history, assessment, and management of a 67-year-old patient with this diagnosis, and then discuss the challenges in managing N2 disease, as well as the roles of systemic therapy, surgery, and postoperative radiation therapy.
