Abstract This paper presents a new way quilters select rulers 6x24 to calculate productivity of five-spot pattern at high water cut stages.In low permeability reservoirs, it is difficult for the reservoir fluid to flow, and the recovery factor is very low.Being based on the non-Darcy flow in low permeability reservoir, taking threshold pressure gra
With a fiber pigtailed electro-optic modulator as the active Q-switch, mode-hopping-free single-longitudinal-mode pulses are generated by a ring cavity fiber laser baltimore a minuit based on the injection seeding technique.The experimental results show that the single-longitudinal-mode oscillating properties of the laser may be determined by the p
Dynamic manipulation of wavefront is vital for massive free-space optical applications.Here we propose a set of largely tunable circular polarization splitters leveraging graphene nanoantennas with high efficiency reaching 83% and wide frequency tunability range of 2 to 5 THz.By synergizing the electrically baltimore a minuit tunable surface plasmo
Background: fbd191blrc Having inadequate health care systems and poor socio-economic infrastructure, Bangladesh has been braving to contain the impact of current COVID-19 pandemic since March, 2020.To curb the diffusion of COVID-19, the local government has responded to the outbreak by enforcing a set of restricted measures on economic and social a
