background: mannitol is present in the ethyol ® (the trade name of amifostine) as an excipient. the mechanism of radioprotection of amifostine is radical scavenging. since mannitol is another known radical scavenger, we studied the probable additive or synergistic effect of mannitol on the effect of amifostine. material and methods: mice were irradiated with co-60 γ -ray in the presence 400mg/k...

These studies were designed to determine the relative bioavailability and tolerance of tribasic Mn chloride (TBMC) for growing broiler chickens. In experiment 1, birds were fed a basal diet (starter, 102 ppm; grower, 209 ppm) or the basal diet supplemented with 3,600, 4,500, or 5,400 ppm Mn from either TBMC or manganese sulfate (MnSO(4)), and BW, feed intake, and plasma Mn were measured. In exp...

Compositional, microstructural, and magnetic characterization of ZnO 30 Å /Mn x n multilayers prepared by sputtering is presented to study the observed ferromagnetism in the Mn-ZnO system. The nominal Mn layer thickness, x, is varied from 3 to 60 Å, while the number of bilayers, n, is increased to maintain the total amount of Mn constant. Microstructure information was deduced from x-ray reflec...

Silicoaluminophosphate (SAPO-34) molecular sieve doped with transition metals, Mn and Ni, with different molar ratios (Mn/Ni=0.33, 3) were investigated for their activity, selectivity and lifetime in biomethanol to olefins reaction. MnNiAPSO-34 nanostructured catalyst was synthesized by hydrothermal method and addition of metals was carried out by isomorphous substitution into the crystalline f...

mechanical alloying of binary and ternary elemental powder mixtures with the nominal compositions of mg2ni and mg(2-x)mnxni (x= 0, 0.05, 0.10 and 0.15 at. %) were carried out in a planetary ball mill for various milling times of 5, 10, 15, 20, 30 and 60 h. x-ray diffraction and field emission scanning and transmission electron microscopy were used for the characterization of the milled products...

Biogenic Mn oxides were produced by the bacterium Leptothrix discophora SS-1 (= ATCC 3182) in a chemically defined mineral salts medium, and the Pb binding and specific surface area of these oxides were characterized. Growth of SS-1 in the defined medium with pyruvate as a carbon and energy source required the addition of vitamin B12. Complete oxidation of Mn(II) within 60 h required the additi...

An ion storage technique, based on the capture of metastable multiply charged ions from an external ion source into a Kingdon ion trap, has been used to measure the lifetimes of eight metastable levels of Mn ions with 3s3p configurations, k51 – 4. Although several lifetime calculations exist, some of the transition wavelengths have not been previously observed in any source. The lifetimes range...

The study was carried out for two consecutive years (2005-06 to 2006-07) to evaluate the wheat response to five different levels (0, 4, 8, 12 and 16 kg ha) of manganese (Mn) alongwith 150-100-60 kg NPK ha application. The experiment was laid out in randomized complete block design (RCBD) with three repeats under irrigated conditions at Agriculture Research Farm Karor, District Layyah. NPK was a...
