Abstract:

An improved aqueous electrocoating composition containing an anticrater additive which is a reaction product of silane component based on glycidoxy propyl tri methoxysilane and poly oxy propylene diamine. Materials were studied by infrared spectroscopy and particle size analyzer. Crater number of electrocoated sample was evaluated by GM9532p standard. The final electrocoat contains anticrater agent produces coating having a smoother appearance with fewer craters.

Recent Advances in PET-MR Hybrid contrast agent

Introduction: All of the Imaging modalities have advantages and disadvantages alone. So if we want to have the best and perfect image, combining these modalities produces something we desired. PET-MR images consist of morphologic and metabolic data. MRI and PET provide high spatial and contrast resolution and high sensitivity and molecular information respectively. Hybrid PET-...

Main ingredients in herbal formulation may act as preservative agent

Background & Aim:Nowadays, the use of chemical preservatives has been limited due to the controversial adverse effects. In this study, we evaluated the preservative potency of product with active herbal ingredients (Barij Baby cream) in contrast with the same products with two different chemical preservatives including methylparaben plus propylparaben and potassium sorbate plus...

Hybrid Multi-agent Planning

Although several approaches have been constructed for multi-agent planning, solving large planning problems is still quite difficult. In this paper, we present a new approach that integrates landmark preprocessing technique in the context of hierarchical planning with multi-agent planning. Our approach uses Dependent and Independent clustering techniques to break up the planning problem into sm...

Synthesized Gd2O3 nanoparticles as contrast agent

Introduction: Gd (III) ion has been known to be the best metal ion in the periodic table that can be used as a T1 MRI contrast agent. Gadolinium have 7 unpaired electrons and these electrons can make magnetic area. No other metal ions possess unpaired electron more than this. CAs based on the element Gd are classified as “positive”, by opposition to “negative” CAs. Nowadays, G...

Hybrid Cloud System and Software Agent: Towards Hybrid Cloud Intelligent Agent System

Clouds are used through a service-oriented interface that implements the "as-a-service" paradigm to offer cloud services on demand. The adaptation of cloud users and clouds services and application needs required large-scale infrastructures for high-performance computing, since this could be provided only by cloud computing. This paper discusses the cloud computing models, services and architec...
