The lateral-torsional buckling of tapered thin-walled beams with singly-symmetric cross-section has been investigated before.For instance, the power series method has been previously utilized to simulate the problem, as well as the finite element method.Although such methods are capable of predicting the critical buckling loads with the desired pre
Background: While the proliferation of social media is hailed for increasing corporate business networking and competitiveness, this claim has tc electronic honey pot not been sufficiently tested in tourism small, medium and micro enterprises (SMMEs) in African emerging economies where traditional communication modes tend to dominate.Setting: This
We suppose that the dramatic decline in the European output is more than a cyclical diversion from the potential output.We performed a medium term quantitative analysis combining data based on the production function and growth accounting approach.Our 2003 kia spectra catalytic converter results show that the erosion of the European growth potentia
Tyrosinase is a copper-binding enzyme involved in melanin biosynthesis.However, the detailed structure of human tyrosinase has not yet been solved, along with the identification of the key sites responsible for its catalytic activity.We used site-directed mutagenesis to identify the residues critical for the copper binding of human tyrosinase.Seven
