Multi-photon intravital imaging has become a powerful tool to investigate the healthy and diseased brain vasculature in living animals. Although agents for multi-photon fluorescence microscopy of the microvasculature are available, issues related to stability, bioavailability, toxicity, cost or chemical adaptability remain to be solved. In particular, there is a need for highly fluorescent dyes...
The situation in particle physics today is highly analogous to that which existed in chemistry towards the end pf the 19th century. During the preceding two centuries, remarkable progress has been achieved in that discipline, progress that culminated in the periodic table of Mendeleyev. This table summarieed not only the realieation that our everyday matter is composed of basic building blocks,...
Pyrolysis essentially is the thermal decomposition of organic matter under inert atmospheric conditions or in a limited supply of air, leading to the release of volatiles and formation of char. Modeling of pyrolysis implies the representation of the chemical and physical phenomena in a mathematical form. In this study, Differential Evolution (DE) algorithm is applied and global optimum set of k...
As reflected in the literature, solid-fluid flow characteristics in spouted beds can vary widely when particles are coated by a suspension. This work is aimed at describing the effect of interparticle forces on airflow distribution in conical spouted beds of inert particles coated by Eucalyptus black liquor. The simulator developed earlier is modified to incorporate this effect. Two corrective ...
Measurement of the extragalactic background (EGBR) of diffuse gammarays is perhaps one of the most challenging tasks for future gammaray observatories, such as GLAST. This is because any determination will depend on accurate subtraction of the galactic diffuse and celestial foregrounds, as well as point sources. However, the EGBR is likely to contain very rich information about the high energy-...
Multi-electrode plasma torches are becoming increasingly popular in the thermal spray community due to their good stability and high power plasma jet even when operated with inert gases. Currently the models in use feature either three cathodes and a single anode or three individual anodes connecting to a single cathode. The motivation for development of these plasma torches is based on the inh...
We report a method for synthesizing hierarchically structured tin– carbon (Sn–C) composites via aerosol spray pyrolysis. In this method, an aqueous precursor solution containing tin(II) chloride and sucrose is atomized, and the resultant aerosol droplets carried by an inert gas are pyrolyzed in a high-temperature tubular furnace. Owing to the unique combination of high reaction temperature and ...
We present a bolus method of inert-gas delivery to the lungs that facilitates application of multiple inert gases and the multiple inert-gas-exchange technique (MIGET) model to noninvasive measurements of cardiac output (CO) and central mixed venous oxygen content Reduction in recirculation error is made possible by 1) replacement of sinusoidal input functions with impulse inputs and 2) replace...
Combining particles and polymers provides materials with unique mechanical properties. Hereby, the character of particle surface is important for network However, particle-polymer interfaces food systems are scarcely controllable. This often leads to an indefinite contribution on Developing hybrid artificial by using inert a well-defined coating represents new approach in science. Coating funct...
Background and purpose: Radon is a colorless inert gas which decay products are the main component of natural radioactive elements that are naturally produced in under layers of earth crust by decay of radium and uranium. It enters through buildings via gaps and cracks. Alpha particle emissions as a radon gas decay product can increase the incidence of lung cancer in human. Every person spends ...
