How to make a magnetosphere
originates from the Sun and expands radially into the interplanetary space. As it encounters the various bodies in the solar system it creates a variety of disturbances depending on the effective size of the obstacle. Two measures are important: the gyroradius, ρi, is the radius of the particle orbit around the magnetic field (B) due to the Lorentz force, and is given by ρ= vth /Ω= vthm / qB, w...
متن کاملHow to make a helix
lant stems twist and turn with the help of aberrant microtubule structures, according to results from Siripong Thitamadee, Kazuko Tuchihara, and Takashi Hashimoto (Nara Institute of Science and Technology, Ikoma, Japan). The insights come from studies of Arabidopsis thaliana , which normally grows straight. Hashimoto’s team isolated lefty1 and lefty2 —which have left-handed helical growth—as su...
متن کاملHow to make a lysosome
How to make a lysosome oated vesicles had been described as early as 1961. These small membranous structures were characterized by a highly organized layer of material on the cytoplasmic surface, “but no one knew their function,” says Marilyn Farquhar, whose lab at the time had become interested in how the Golgi complex helped produce enzymes. Roth and Porter (1964) had provided evidence that c...
متن کاملHow to make a hybridoma.
The use of monoclonal antibodies produced by the hybridoma technique has had a profound impact on the biological and medical sciences. While the general technique for the production of monoclonal antibodies is available from the numerous papers which report their use, there is a need for a source which describes the procedure and its pitfalls in detail so that an investigator who decides to mak...
متن کاملA Simulation-Optimization Model For Capacity Coordination In Make To Stock/Make To Order Production Environments
Capacity coordination, as the tactical level of hierarchical production planning in hybrid MTS/MTO systems, includes numerous important decisions. In this paper, two of these decisions i.e. finding the best strategy for the acceptance/rejection of incoming orders and determining orders’ due dates – are investigated. Also a simulation model is proposed to evaluate the efficiency of the presented...
