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...

Micro/nano-structured CaWO4/Bi2WO6 composite: synthesis, characterization and photocatalytic properties for degradation of organic contaminants.

The micro/nano-structured CaWO(4)/Bi(2)WO(6) composite was successfully synthesized by a one-step hydrothermal route without using any templates or surfactants. The as-prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-vis diffuse reflectance spectroscopy (UV-vis DRS), Fourier transform infrared (FT-IR) ...

Mathematical Modeling for Volatile Organic Compounds Removal in a Biofilter: Model Validation and Sensitivity Analysis

Mesoporous ferrihydrite with incorporated manganese for rapid removal of organic contaminants in air.

Mesoporous ferrihydrite nanoparticles with incorporated Mn (MMnFh) were prepared for the first time, and MMnFh exhibits excellent performance in removing organic contaminants (CH(3)CHO and toluene) in air. The interesting physico-chemical properties and remarkable activity of MMnFh give great commercial potential in air purification application in diverse sectors.

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
