This paper deals with the singular nonlinear third-order periodic boundary value problem u′″ + ρau = f(t,u), 0 ≤ t ≤ 2π, with u(i)(0) = u(i)(2π), i = 0,
Based on the extended homogeneous capacity hihg precision integration method and the spetrum method of virtual boundary with a complex radius vector, a novel se
We derive the exchange currents of pseudoscalar, vector, and scalar mesons from Feynman diagrams, and use them to calculate the magnetic form factors of nucleon
The carbon content in the fly ash from most Chinese circulating fluidized bed (CFB) boilers is much higher than expected, thus directly influencing the combusti
The associations of each of midecamycin and chloroquine phosphate to hydrogen peroxide were studied by using linear-potential scan polarography. In a 0.15 mol/L
The co-crystallization of tetra-iso-butyl-resorcin[4]arene 1 and 2,6-diacetyl- pyridine (Ac2py) from MeCN/CH2Cl2 yielded a multi-component complex 1(Ac2py(2H2O(
Objective: To elucidate the clinical features and prognosis of multiple primary cancers, in order to make improvement of diagnosis and treatment. Methods: A tot
According to the data of main environmental factors and the depth of localized corrosion of carbon steel and low alloy steels in China seas, combined with the r
The effects of the incorporated oxygen and the different buffer layers on the optical properties and surface morphology of GaN were studied. The results show th
