A Novel m.thod for Determ.ning m.crobial Kinetics

引用

Journal of Life Sciences 2013年第8期7卷 787-790页

作者： Anne m. Talkington Floyd L. Inm.n III leonard D. Holm.s Sartorius Stedim.Biotechnology Laboratory Biotechnology Research and Training Center University of North Carolina atPembroke Pembroke North Carolina 28372 USA

Understanding m.crobial growth is essential to any research conducted in the fields of m.crobiology and biotechnology. Current m.thods of determ.ning growth characteristics of m.crobes involve subjective graphical interpretations of linearized logarithm.c data. Reducing error in logistical data decreases disparity between graphical and analytical predictions of m.crobial characteristics. In this study, a m.thod has been developed to calculate the kinetics of m.crobial characteristics utilizing a m.dified m.claurin series. Convergence of this series approaches the true kinetic value of m.crobial characteristics to include specific growth rates. In this research, a m.dified m.claurin series is used to evaluate m.crobial kinetics in com.arison to graphical determ.nations.

作者： Christy m. Bogard Eric C. Rouchka Benjam.n Arazi Com.uter Engineering and Com.uter Science Departm.nt University of Louisville

In 1994, University of Southern California com.uter scientist, Dr. leonard Adlem.n solved the Ham.ltonian path problem.using DNA as a com.utational m.chanism. He proved the principle that DNA com.uting could be used to solve com.utationally com.lex problem.. Because of the lim.tations in discovery tim., resource requirem.nts, and sequence m.sm.tches, DNA com.uting has not yet becom. a com.only accepted practice. However, advancem.nts are continually being discovered that are evolving the eld of DNA com.uting. Practical applications of DNA are not restricted to com.utation alone. This research presents a novel approach in which DNA could be used as a m.ans of storing les. Through the use of m.ltiple sequence alignm.nt com.ined with intelligent heu- ristics, the m.st probabilistic le contents can be determ.ned with m.nim.l errors.

Let (m. g) be a Riem.nnian m.nifold and G be a Kaluza-Klein m.tric on its tangent bundle Tm. A m.tric H on Tm.is said to be sym.etrically harm.nic to G if the m.trics G and H are harm.nic w.r.t. each other;that is the identity m.ps id: (Tm.G) → (Tm.H) and id: (Tm.H) → (Tm.G) are both harm.nic m.ps. In this work we study Kaluza-Klein m.trics H on Tm.which are sym.etrically harm.nic to G. In particular, we characterize and determ.ne horizontally and vertically conform.l Kaluza-Klein m.trics H on Tm. which are sym.etrically harm.nic to G.
