Seedling Emergence and Biomass Growth of Oleaginous and Other Tropical Species in Oil Contaminated Soil

Germination rate in contaminated soils cannot be used as the sole indicator to select suitable species for phytoremediation trials, since it does not predict the plant development after germination. As a result, most screening tests for selection of specie with phytoremediation potential to treat contaminated soils include germination rate and biomass production. These screenings take several m...

an application of equilibrium model for crude oil tanker ships insurance futures in iran

با توجه به تحریم های بین المملی علیه صنعت بیمه ایران امکان استفاده از بازارهای بین المملی بیمه ای برای نفتکش های ایرانی وجود ندارد. از طرفی از آنجایی که یکی از نوآوری های اخیر استفاده از بازارهای مالی به منظور ریسک های فاجعه آمیز می باشد. از اینرو در این پایان نامه سعی شده است با استفاده از این نوآوری ها با طراحی اوراق اختیارات راهی نو جهت بیمه گردن نفت کش های ایرانی ارائه نمود. از آنجایی که بر...

Mei – A Module System for Mechanized

This thesis presents several module systems, in particular Mei and DMei, designed for mechanized mathematics systems. Mei is a λ-calculus style module system that supports higher-order functors in a natural way. The semantics of functor application is based on substitution. A novel coercion mechanism integrates a parameter passing mechanism based on theory interpretations with simple λ-calculus...

Plant Biology: Seedling Emergence through Soil

The resistance encountered by a seedling as it pushes through the soil causes inhibition of stem elongation and stimulates stem thickening, facilitating soil penetration. A new study demonstrates that two proteolytic pathways work in double-negative fashion - one targeting the other - to protect transcription factors central to this response.
