a gas permeation model (coupling model) has been developed which has the flexibility to be used for different membrane module configurations. the aim of this work is to predict the performance of a single stage gas separation process using membranes and provide a comprehensive description of process parameters like flow rates, composition, stage cut and stream pressure. the significant feature ...

Immunomagnetic sorting of natural killer (NK) cells from the peripheral blood of healthy donors has been evaluated in a comparative study of composition, yield and activation of target cells obtained by positive (Dynabeads, Microbeads) and negative (Microbeads) sorting procedures. Positively sorted target cells were selected by expression of the NK cell marker CD56, whereas NK cells obtained by...

cantaloupe (cucumis melo) volume was measured using water displacement and image processing methods. the volume determined from image processing method was compared to the volume determined by the water displacement method using the paired samples t-test and the bland-altman approach. the paired samples t-test results showed that the volume determined by image processing method was not signific...

Separation of developing cells into fractions of differing stages of maturity is critical to effective biochemical study of the process of cellular differentiation. Density gradient techniques utilizing rate-zonal or isopycnic separations have permitted partial separations based on cell mass or cell density. In this study the separation of various rabbit marrow cells was improved by high-speed ...

In all recent near-optimal sorting algorithms for meshes, the packets are sorted with respect to some snake-like indexing. In this paper we present deterministic algorithms for sorting with respect to the more natural row-major indexing. For 1-1 sorting on an n n mesh, we give an algorithm that runs in 2 n+ o(n) steps, matching the distance bound, with maximal queue size five. It is considerabl...

Radio frequency (RF) stealth is one of the essential research hotspots in radar field. The anti-sorting signal an important direction RF signal. Theoretically speaking, design based on failure principle sorting algorithm, and SDIF algorithm a core widely used engineering. Thus, this paper, first analyzed detail. It pointed out that threshold function will fail when pulse repetition interval (PR...

background: generation of an effective dendritic cell (dc) based cancer vaccine depends on appropriate differentiation of monocytes in vitro. objective: to compare the effects of monocyte separation methods, flask adherence (flask-dc) and magnetic activated cell sorting (macs-dc), on phenotypic and functional characteristics of resultant dcs. methods: dcs from healthy volunteers were generated ...

Spike sorting is a class of techniques used in the analysis of electrophysiological data. Studying the dynamics of neural activity via electrical recording relies on the ability to detect and sort neural spikes recorded from a number of neurons by the same electrode. This article reviews methods for detecting and classifying action potentials, a problem commonly referred to as spike sorting.

This paper studies new properties of the front and back ends of a sorting network, and illustrates the utility of these in the search for new bounds on optimal sorting networks. Search focuses first on the “outsides” of the network and then on the inner part. All previous works focus only on properties of the front end of networks and on how to apply these to break symmetries in the search. The...

in this study, an intelligent system for sorting closed shell and open shell pistachio nuts, was designed and developed based on combined acoustic and artificial neural network (ann) techniques. the system included a microphone, pc, material handling equipment and an air reject pneumatic mechanism. the microphone, placed under the steel plate, received sound signals generated by the pistachio n...
