introduction: chronic liver disease and cirrhosis are the most important causes of growth failure, morbidity and mortality in children. cirrhosis consists of a variety of congenital, genetic, metabolic, and infectious causes in children. models for predicting of chronic liver disease severity, survival, and transplantation are useful for decision-making as well as medical interventions. the mos...

This AMEE Guide offers an introduction to research in medical education. It is intended for those who are contemplating conducting research in medical education but are new to the field. The Guide is structured around the process of transforming ideas and problems into researchable questions, choosing a research approach that is appropriate to the purpose of the study and considering the indivi...

Volatile organic compounds (VOCs) have a great influence on tropospheric chemistry; they affect ozone formation and they or their reaction products are able to take part in secondary organic aerosol formation; some of the VOCs are themselves toxic. Knowing the concentrations and sources of different reactive volatile organic compounds is essential for the development of ozone control strategies...

Based on the theory of relativistic mean-field effective interactions, we explore effect superstrong magnetic fields (SMFs) nuclear single-particle level structure, blinding energy, and electron Fermi energy in strongly magnetized super-Chandrasekhar white dwarfs (SMSWDs). We also discuss capture (EC) instability from threshold mass density (TMD) pressure (TP) for some typical iron group nuclei...

We investigate the equation (ut + (f(u))x)x = f (u)(ux)/2 where f(u) is a given smooth function. Typically f(u) = u/2 or u/3. This equation models unidirectional and weakly nonlinear waves for the variational wave equation utt − c(u)(c(u)ux)x = 0 which models some liquid crystals with a natural sinusoidal c. The equation itself is also the Euler-Lagrange equation of a variational problem. Two n...
