Lactobacillus fermenti strain 36 is the most frequently used microorganism for the assay of thiamine both in the tube method, (Sarett and Cheldelin, 1944; Fitzgerald and Hughes, 1949), and in the plate method, (Bacharach and Cuthbertson, 1948; Jones and Morris, 1949). Other microorganisms have more recently been suggested for the tube assay; Hoff-Jorgensen and Hansen (1955) used the yeast Kloec...

The vacuum suction cup is often used as an end effector and widely in wall-climbing operations. However, there are few designs applications for oil-immersed substrates. Inspired by the surface morphology of octopus sucker, bionic cups with different numbers, diameters, spacings ring grooves were designed. Their normal adsorption force was evaluated on untreated polished steel plate oil. test re...

Antimicrobial activity of different parts of Croccus sativus L. (saffron) including stigma, stamen, leaves and colora, extracted by various solvents, were tested against different bacteria (Microccucos luteus, Staphylococcus epidermitis, Staphylococcus aureus and E. coli) and fungi (Candida albicans, Aspergillus niger and Cladospourium sp) by cup plate diffusion method. Minimal Inhibitory Conce...

People are tool-makers, but today we often depend on centralized fabrication for our tools. This paper explores the user experience opportunities demonstrated in a case study of a computer-controlled domestic fabrication system. Specifically we explore several approaches to creating a dish-maker that would create dishes on demand under computer control. The Dishmaker can create cups, bowls and ...

(saffron) including stigma, stamen, leaves and colora, extracted by various solvents, were tested against different bacteria (microccucos luteus, staphylococcus epidermitis, staphylococcus aureus and e. coli) and fungi (candida albicans, aspergillus niger and cladospourium sp) by cup plate diffusion method. minimal inhibitory conce...

The methanol extract of wax gourd, the fruits of Benincasa hispida cogn.(Cucurbitaceae) was found to show no inhibition against three gram positive bacteria Staphylococcus aureus, Staphylococcus epidermidis, and Bacillus subtilis and three gram negative bacteria Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumonia by cup-plate method whereas antifungal studies showed significant in...

Antibacterial activity of aqueous and ethanol leaf extracts of Cadaba trifoliata was evaluated by cup plate method against bacterial strains such as Staphylococcus aureus, Bacillus subtilis, Acinetobacter, Enterobacter aerogenes, Erwinia and Escherichia coli. The ethanol extract of the leaves demonstrated a high degree of activity against all the tested bacterial strains except Erwinia and Acin...
