A chlorite “hand-bag” belonging to the once-called “intercultural style” production, currently on exhibit in the NationalArchaeological Museum, Tehran, is described focusing attention, for the first time, to the peculiar wear traces clearlyvisible on the handle and along its contour. The strong wear suggests that the hand-bag was suspended for a long time ona cord; and that in this setting it w...

-Chlor i te-mica aggregates in slates from northern Spain have been investigated in very-thin thin sections. Specimens from various parts of a fold show different morphologies that are dependent on the operating deformation mechanism. From the limb to the hinge rigid-body rotation becomes less important and folding and intragranular kinking are more common. This is associated with an increasing...

[Purpose] Gait velocity and trunk acceleration during semicircular turning gait with and without carrying a hand-held bag were compared in females of very advanced age. [Subjects and Methods] Ten female volunteers of very advanced age who could walk independently were recruited for this study. Gait velocity and trunk acceleration were measured using an accelerometer during semicircular turning ...

cis-[Ru(2,9-Me(2)phen)(2)(OH(2))(2)](2+) reacts readily with chlorite at room temperature at pH 4.9 and 6.8. The ruthenium(II) complex can catalyze the disproportionation of chlorite to chlorate and chloride, the oxidation of chlorite to chlorine dioxide, as well as the oxidation of alcohols by chlorite.

Chloroperoxidase and horseradish peroxidase use NaClOz as both the oxidant and the halogen donor for the peroxidative chlorination of monochlorodimedone. Previous studies have shown that both horseradish peroxidase and chloroperoxidase can catalyze iodination reactions with hydrogen peroxide as the oxidant; however, only chloroperoxidase catalyzes chlorination reactions under these conditions. ...

Horseradish peroxidase and chlorite, NaC102, are able to catalyze chlorination of monochlorodimedone to form dichlorodimedone. Catalytic amounts of horseradish peroxidase act to disproportionate chlorite forming chlorine dioxide and chloride ion. The chlorine dioxide thus formed is responsible for the chlorination of monochlorodimedone. It was previously thought (Chiang, R., Rand-Meir, T., Maki...

-The chemical compositions ofchlorite-smectite mixed-layered minerals (C/S) from the Ohyu caldera (lnoue, 1985) are analyzed using M+-4Si-3R 2§ diagrams. The assumed original saponite has the following composition: Si3.54Alo.460 ~ 0Alo. ~7~Fe 2§ ~.385Mg1.z95Mn0.o2(OH)2M+o.56. Random C/S minerals ( 100 to 80% expandable layers) are interpreted as an interstratification of the starting 2:1 smecti...

A compilation of Fe-bearing chlorite analyses is used: (1) to investigate the Alfree di-trioctahedral (AFDT) substitution 2Fe +□ = 3(Mg,Fe) in chlorite; and (2) to estimate the composition of a ferri-sudoite end-member (Si3Al)[(Fe ,Mg)2Fe 3+ 2 □Al]O10(OH)8 within the chlorite solid-solution domain. According to our observations, up to two Fe cations might be allocated in the M2-M3 chlorite site...

the structure of the materials inside a medical bag needs to be arranged in such a manner, that the treating physician to be able, even blindfolded, to quite his way through, in order to easy grasp every instrument and tool. this was an axiom firstly recorded by hippocrates in ancient greece. on the other hand, egyptians and palestinians used medical kids at about the same era, followed in late...

Chlorite dismutases are prokaryotic heme b oxidoreductases that convert chlorite to chloride and dioxygen. It has been postulated that during turnover hypochlorite is formed transiently, which might be responsible for the observed irreversible inactivation of these iron proteins. The only charged distal residue in the heme cavity is a conserved and mobile arginine, but its role in catalysis and...
