Introduction: The mesosiderites are amongst the most enigmatic of all the meteorite groups and their formation is not fully understood. Evidence taken from both the metal and silicate portions indicates that they have a multi-stage formation history [1,2]: 1. Initial crystallization and cooling of silicates, followed by brecciation on the surface of the parent body 2. Metal-silicate mixing, som...

In this article, modeling in queuing systems with heavy traffic customer flows is reviewed. Key areas include their limiting distributions, asymptotic behaviors, modeling issues and applications. Heavy traffic flows are features of queuing in modern communications, transportation and computer systems today. Initially, we reviewed the onset of asymptotic modeling for heavy traffic single server ...

Introduction: Impact cratering is one of the dominant geologic processes affecting asteroids. It results in shock-induced melting and the formation of impactites, including impact melt breccias. Meteoritic samples of these breccias possess petrologic and geochemical signatures that can be used to deduce the collisional evolution of the respective parent body, such as the timing of the event, sh...

Background and Aims: Coated nanoparticles have different surface chemistry, aggregation, and interaction properties. The aim of this study was to investigate the cytotoxicity of silver nanoparticles AgNPs coated with different proteins on Balb/c macrophages. Materials and Methods: In this study these items were evaluated: 1) the size of aggregation, 2) the quantity and mechanisms of uptake, ...

In this paper, we propose a transportation network efficiency measure that can be used to assess the performance of a transportation network and which differs from other proposed measures, including complex network measures, in that it captures flows, costs, and travel behavior information, along with the topology. The new transportation network efficiency measure allows one to determine the cr...

There is currently much interest in producing biofuel-based transportation fuels. However, since biofuel is a limited renewable resource, it is important to assess whether such fuels are both produced and used as efficiently as possible. Efficient production can be achieved in the future by integrated biorefinery operations at pulp mill sites, co-producing pulp and biofuel-based energy products...

As a subsystem of an Intelligent Transportation System (ITS), an Advanced Traveller Information System (ATIS) disseminates real-time traffic information to travellers. This paper analyses traffic flows data, describes methodology of traffic flows data processing and visualization in digital ArcGIS online maps. Calculation based on real time traffic data from equipped traffic sensors in Vilnius ...
