For the regeneration of shoots, leaf segments of Rehmannia elata were cultured on Murashige and Skoog (MS) medium supplemented with various concentrations of 6-benzylaminopurine (BAP) (1, 2, or 4 mg L-1) with or without 1-naphthalene acetic acid (NAA) used at 0.1 or 0.5 mg L-1. Regenerated shoots were obtained from the leaf cultures at all BAP(More)

In today's transnational admission environment, evaluating applicant qualifications is becoming increasingly challenging. While standardized tests can be helpful, studies have shown that they are rather noisy predictors of performance. Predicting educational outcome is a viable alternative in such heterogeneous environments. Performance prediction models(More)

— DDoS is one of the most dangerous methods to attack victim network because it uses a vast quantity of distributed agents to make victim paralyze. This paper gives a DDoS defense method which is based on " pushback and communicate " idea (PaC method). When the gateway of victim detects DDoS attack, it has to listen on interfaces to define the neighbors(More)
In many universities it would be useful to have a database of publications that reflects the research results of the academic staffs. Such a database can be built by automatically retrieve publication information from faculties' homepage. In this project, we deploy focused crawling to build such a system. We also proposed a new focused crawling heuristics(More)
White or light purple flower color Torenia (Torenia fournieri Lind.) varieties were successfully developed from the parental variety having violet flowers. This was accomplished by reducing Fe micronutrient in the culture media for the induction of in vitro flowering. The flower induction was highest in modified Murashige and Skoog (MS) medium containing ½(More)
Evolution of structure of spherical SiO 2 nanoparticles upon cooling from the melt has been investigated via molecular-dynamics (MD) simulations under non-periodic boundary conditions (NPBC). We use the pair interatomic potentials which have weak Coulomb interaction and Morse type short-range interaction. The change in structure of SiO 2 nanoparticles upon(More)
