linum persicum is an endangered plant native to iran, from linaceae family. phytochemical analysis has shown that l. persicum in vitro cultures contain podophyllotoxin (ptox), the pharmacological precursor for anticancer drugs such as etoposide, etopophos, and teniposide. shoot culture of l. persicum was established from callus cultures in ms medium containing ga3. a study was designed to inves...

Using a world trade model with India subdivided into states, the paper examines how regional disparities are affected by domestic inter-state trade as well as international trade. According to the analysis, international liberalisation promotes decentralisation and convergence, not divergence, so trade is not to blame for India’s growing regional disparities. High economic growth within India m...

We are interested in the balance of energy and protein synthesis in bacterial growth. How has evolution optimized this balance? We describe an analytical model that leverages extensive literature data on growth laws to infer the underlying fitness landscape and to draw inferences about what evolution has optimized in Escherichia coli. Is E. coli optimized for growth speed, energy efficiency, or...

staphylococcus aureus is one of the most prevalent causes of gastroenteritis worldwide. knowing the precise boundary for the growth/no growth interface of s. aureus and also determining the period of time needed for bacterial growth initiation is necessary for food safety risk assessment. this study was designed to examine the combined effects of temperature, acetic acid, inoculum level and nac...

the growth rate of carbon nanotubes in chemical vapor deposition is simulated by using a theoretical analysis of the phonon vibration of the system. simulations demonstrate that the growth rate of carbon nanotubes with larger diameters is smaller because of higher damping factors and carbon nanotube inertia. an optimum temperature for the growth rate is calculated for a carbon nanotube on fe ca...

rapidly increasing urbanization in the world, especially in developing countries, let to increasing urban extents. rapid urban growth causes to appearance many problems such as wasting environmental resources, inability of providing necessary services for citizens and unplanned growth. urban mangers and planners need tools for understanding amount and size of future urban growths to prevent the...
