AbstractIn this paper, we investigate effect of Fe–intermetallic compounds on plastic deformation of closed-cell composite Aluminum Foam as filler of thin-walled tubes. However, deformation of the Aluminum foam-filled thin-walled tubes as crushed-box will be presented in Part (II). Composite foams of AlSi7SiC3 and AlSi7SiC3-(Fe) as closed cell were synthesized by powder metallurgy foaming metho...

The following bacteria were employed as test organisms: Lactobacillus fermenti strain 69L-3, Escherichia coli strain 69L-15, and Serratia marcescens strain ATCC 274. They were cultivated as outlined previously (Major et al., 1955). Broth cultures of the organisms were centrifuged, the spent broth pipetted off, the cells resuspended in a minimal amount of fresh broth, and then the suspension dil...

The response of M. lyodeiktiwu to biotin or other nutrients was determined by turbidimetric measurement of growth. Five ml of test medium contained in aluminum-capped test tubes were used in each assay. Additions to 4 ml of basal medium varied the composition of the nutrient material. The basal medium (no. 1) (table 1) was stored under toluene in the refrigerator and aliquots withdrawn aseptica...

background and aims. biocompatibility of root-end filling materials is a matter of debate. the aim of this study was to compare the biocompatibility of a variety of commercial proroot wmta cements and a resin-based cement (geristore®) with different ph values of setting reaction and different aluminum contents, implanted into the subcutaneous connective tissue of rats at various time intervals....

• Novel Ionic Liquid that is not corrosive to aluminum used as liquid desiccant. New three-fluid fin-tube desiccant contactor fabricated using aluminum. Experimental performance of the IL solution investigated. The fin–tube showed superior than packed bed contactor. Lower flow rates and pumping power expected experimental a new novel ionic investigated compared with those an adiabatic LiCl for ...

This paper presents investigations of thimble ionization chamber response in medium-energy kilovoltage x-ray beams (70-280 kVp, 0.09-3.40 mm Cu HVL). Two thimble ionization chambers (PTW30015 and PTW30016) were investigated, regarding the influence of the central electrode dimensions made of aluminum. Measurements were carried out in photon fields of different beam quality. Corresponding Monte ...
