obtaining a continuous source of normal cells or dna from a single individual has always been a rate limiting step in biomedical research. availability of lymphoblastoid cell lines (lcls) as a surrogate for isolated or cryopreserved peripheral blood lymphocytes has substantially accelerated the process of biological investigations. lcls can be established by in vitro infection of resting b cell...

This work presents a new method of fabricating implantable multielectrode arrays on lightly doped single-crystal silicon. Such arrays are essential tools for electrical stimulation and recording of nerve signals. Our new microfabrication process, based on silicon-on-insulator (SOI) technology, inherently has excellent control over the final probe thickness without wet etching. The needle shanks...

The evaporation of sprinkler droplets is an important phenomena in fire simulations both for heat removal from the gas and for heat removal from surfaces. The Fire Dynamics Simulator (FDS) has seen a number of different evaporation models over its history where each subsequent model has attempted to address limitations and issues with the previous model. In this paper, we address the problems o...

Here, the population transfer between two specific levels of Cesium atomunder the influence of chirped laser source has been numerically investigated. The maingoal of this study is the engineering of the population transfer between the 62S1/2 and 62P1/2levels of Cesium which is corresponding to its D1 transition line using a chirped lasersource. Constructing the system Hamiltonian, as well as t...

Phenamiphos, ethoprop, and carbofuran each at 6.7 kg a.i./ha were applied to squash, southern pea, and corn via injection into a sprinkler irrigation system. This method was then compared with a conventional application of phenamiphos and ethoprop granules spread on the soil surface and incorporated into the top 15 cm for control of Macroposthonia ornata and Meloidogyne incognita. Nematode popu...

In this paper, a Fast Fuzzy processor (FP) is proposed. This processor, which is implemented using FPGA, has four inputs and one output with 8-bits width for each. The proposed processor is synthesized, functionally verified and implemented using Xilinx Integrated Software Environment (ISE) and is tested using Xilinx Spartan 3E starter kit. A PC Graphical User Interface (GUI) is programmed usin...

  A novel compact fiber-coupled NIR system based on a DFB diode laser source is employed as a portable and sensitive gas sensor for trace detection of combustion pollutant molecules. We demonstrate the performance of such an NIR gas sensor by tracing the absorption lines of CO and CH4 using 2f-WMS technique at moderate temperature of T ~ 600°C in the recuperator channel of an industrial furnace...

The present work solves two-dimensional Advection-Dispersion Equation (ADE) in a semi-infinite domain. A variable source concentration is regarded as the monotonic decreasing function at the source boundary (x=0). Depth-dependent variables are considered to incorporate real life situations in this modeling study, with zero flux condition assumed to occur at the exit boundary of the domain, i.e....
