Structural analysis of new devices to be used in centrifuge facilities can be a challenging task. Initial calculations, based on simple basic static principles, are usually used. However, as devices placed in a geotechnical centrifuge are often complex structures, advanced analysis methods to assess their performance under enhanced acceleration fields are desirable. This paper presents the anal...

Vulnerability to cavitation curves describe the decrease in xylem hydraulic conductivity as xylem pressure declines. Several techniques for constructing vulnerability curves use centrifugal force to induce negative xylem pressure in stem or root segments. Centrifuge vulnerability curves constructed for long-vesselled species have been hypothesised to overestimate xylem vulnerability to cavitati...

LEVEL: INTERMEDIATE P roduction of monoclonal antibodies from mammalian cell culture has become ubiquitous in the biotechnology industry as companies continue to identify opportunities to treat diseases with such therapeutic proteins. The first step in recovery of secreted antibodies is to remove most insoluble components of the cell culture from the product stream. These components consist of ...

INTRODUCTION Most arrhythmias during centrifuge training are physiological responses to high +Gz stress. However, potentially dangerous arrhythmias occasionally occur during centrifuge training. We reviewed all arrhythmias recorded during the Japan Air Self-Defense Force (JASDF) centrifuge training from April 2001 to March 2003, and developed a criterion for suspending G-training based on obser...

n-propylsalicylidene based on silica as ion exchanger (ie) was used for the separation by complexation of mn2+, co2+, ni2+, cu2+, hg2+, cr3+, fe3+, and uo22+ from their parent solutions. ie and its metal complexes are characterized by elemental analysis, electronic and infrared spectra, in addition to thermal analysis in atmospheric pressure. the mode of chelation and the proposed geometric str...

one of the most important parameters describing the liposomal formulation of hydroquinone is encapsulation efficacy. for the efficacy evaluation of hydroquinone trapped in liposomal structure, there is a need to first separate liposome from the matrix surrounding it. there are various separation techniques; however, in this study, the three techniques of centrifuges with and without washing and...

A method of quantitatively measuring tissue damage during fresh-cut vegetable processing was developed based on optical imaging technology. Images of damaged and undamaged tissues were acquired through a digital imaging system. The damaged areas were recognized and quantified using an Image-Pro Plus software program based on color differences of the damaged and undamaged tissues. In order to im...
