the use of flow cytometry in the clinical laboratory has grown substantially in the past decade. flow cytometric analysis provides a rapid qualitative and quantitative description of multiple characteristics of individual cells. for example, it is possible to detect the cell size and granularity, aspects of dna and rna content and the presence of cell surface and nuclear markers which are used ...

Carlo A. TRUGENBERGER and Guillermo R. ZEMBA Theory Division, C.E.R.N.** 1211 Geneva 23, Switzerland ABSTRACT The Laughlin states for N interacting electrons at the plateaus of the fractional Hall effect are studied in the thermodynamic limit of large N . It is shown that this limit leads to the semiclassical regime for these states, thereby relating their stability to their semiclassical natur...

Cell motility in viscous fluids is ubiquitous and affects many biological processes, including reproduction, infection and the marine life ecosystem. Here we review the biophysical and mechanical principles of locomotion at the small scales relevant to cell swimming, tens of micrometers and below. At this scale, inertia is unimportant and the Reynolds number is small. Our emphasis is on the sim...

A novel n(4-SPS+SP) serial-parallel manipulator (S-PM) formed by n 4-SPS+SP PMs with four degrees of freedom (DOF) connected in series is proposed in this paper. The kinematics , statics and stiffness modeJ of this seriaJ-PM is established.

the present experimental study reports on enhancement of heat transfer by addition of nanoparticles to the working fluid of commercial swimming pool heat exchangers under laminar flow condition. three different concentrations of titanium dioxide nanoparticles were added to the water as working fluid of a typical forced convective heat exchanger used to transfer heat to public swimming pools. th...

an analytical equation of state has been previously modified by papari et al. for representing the volumetric properties of molecular fluids. however the performance of that eos has not been yet well investigated for refrigerant fluids. this study extended that equation to 19 liquid refrigerants to predict their densities at isothermal and saturated states. two temperature-independent parameter...

background and objectives: meningoencephalitis in iranian children is frequent, but encephalitis is rare .the frequency of hhv-6 and hhv-7 in central nervous system diseases of our children is unclear. the aim of this study was searching the dna-s of hhv-6 & hhv-7 in csf samples of children with meningoencephalitis  materials and methods: a cross sectional study (2007-2009) was done in ped...
