Endocarp morphology of 4 species of Iranian Celtis was examined using light and scanning electron microscopes. Macro- and micro-morphological characters were included endocarp shape, color, size, surrounding rim, ornamentation and SEM structure of the outer layer of the endocarp. Endocarp morphology of the examined specimens exhibit variation in all characters. Endocarp shape varies from globul...

Wtdeband code -dzvzsion multiple access (CD MA) systems are interference-limzted, and so must utilize some form of interference reductzon in order to maintain an acceptable qualtty of service and capacity. In this paper, cochannel interference for several different CDMA architectures is evaluated. For wideband CDMA systems such as WCDMA and cdma2000 with carrier st ealing, co-channel ~nterferen...

We consider the active Brownian particle (ABP) model for a two-dimensional microswimmer with fixed speed, whose direction of swimming changes according to process. The probability density swimmer evolves Fokker-Planck equation defined on configuration space, structure depends swimmer's shape, center rotation and domain swimming. enforce zero flux at boundaries space. derive reduced in an infini...

A new cooling scheme is proposed where the primary working fluid flowing through a micro-channel heat sink is pre-cooled to low temperature using an indirect refrigeration cooling system. Cooling performance was explored using HFE 7100 as working fluid and four different micro-channel sizes. High-speed video imaging was employed to help explain the complex interrelated influences of hydraulic d...

BACKGROUND Bioartificial liver support system (BALSS) based on culturing hepatocytes is an important research field for the treatment of acute liver failure. It is necessary to monitor the state of liver cell functions during the treatment of BALSS in order to guide clinical treatment. OBJECTIVE To design a micro-channel chip to achieve flash mixing for timely detection of liver cell status i...

This paper explores the subcooled nucleate boiling and critical heat flux (CHF) characteristics of a hybrid cooling module that combines the cooling attributes of micro-channel flow and jet impingement. A test module was constructed and tested using HFE-7100 as working fluid. Increasing the coolant’s flow rate and/or subcooling shifted both the onset of boiling (ONB) and CHF to higher heat flux...

The near-wall enrichment of platelets strongly influences thrombus formation in vivo and in vitro . This paper develops a multi-constituent continuum approach to study this phenomenon. A mixture theory model is used to describe the motion of plasma and red blood cells (RBCs) and the interactions between the two components. A transport model is developed to study the influence of the RBCs field ...
