The thermo-optical properties of coated surface are important for spacecraft thermal control coatings which depend on the optical properties and structure of the coating material. These coatings control the temperature by their capability of outer energy absorption and its emission. The optical properties of pigment can be improved if the pigment contains a high fraction of voids in its structu...

The purpose of the current study was to investigate the effect of a high- intensity treadmill running (8 weeks) with or without aqueous extraction of black Crataegus-Pentaegyna (Siyah -Valik) on liver ABCA1 mRNA expression and plasma HDL-C, total, and direct bilirubin concentration in male rats. Twenty Wistar male rats (4-6 weeks old, 140-170 g weight) were used. Animals were randomly assigne...

Introduction: Black pepper (Piper nigrum L.) is one of the medicinal plants being used to prevent and manage stroke in Persian Medicine. Current findings support its anti-inflammatory, radical scavenging and neuroprotective characteristics. In this study, we aimed to evaluate role of black pepper on functional and histopathological outcomes of stroke in an animal model of MCAO. Materials and Me...

Many species of tea (Camellia sinensis) and cowslip (Echium amoenum) are used in Iranian traditional medicine. The aim of this study was to conduct the survey on the ability of Iranian black tea and cowslip extracts on secretion of tumor necrosis factor-alpha (TNF-alpha) by non-infected and infected mouse macrophages. A macrophage infection model with Legionella pneumophila and enzyme linked im...

background. the color masking ability of a restoration plays a significant role in coveringa discolored substructure; how-ever, this optical property of zirconia ceramics has not been clearly determined yet. the aim of this in vitro study was to evaluate the color masking ability of a zirconia ceramic on substrates with different values. methods. ten zirconia disk specimens,0.5 mm in thickness ...

This research proposes a bi-level model for the mixed network design problem (MNDP). The upper level problem involves redesigning the current road links' directions, expanding their capacity, and determining signal settings at intersections to optimize the reserve capacity of the whole system. The lower level problem is the user equilibrium traffic assignment problem. By proving that the optima...

Black box models of technical systems are purely descriptive. They do not explain why a system works the way it does. Thus, black box models are insufficient for some problems. But there are numerous applications, for example, in control engineering, for which a black box model is absolutely sufficient. In this article, we describe a general stochastic framework with which such models can be bu...
