Recently, consumers have become more concerned with foods contain natural ingredients in terms of health and economic. Hence, in this study the effect of concentrate of smoked and sun dried raisin at 3 levels (1, 3 and 5%) as a natural humectant to improve the quality and shelf life of flat bread were investigated. Results showed that addition of smoked and sun dried raisin improved quality and...

A significant part of the primary gold reserves in world is contained sulphide ores, many types which are refractory processing. The deposits ores will be main potential source production future. and silver can associated with micro- nano-sized inclusions Au Ag minerals as well isomorphous, adsorbed other species noble metals (NM) not thoroughly investigated. For gold-bearing Urals, distributio...

this research was conducted to estimate the amount of microbial protein synthesis in iranian buffaloes' rumen. four male swamp buffaloes with average live body weight of 140±10 kg were used in this study. four diets of 0 (control diet, 100% forage), 15, 30 and 45% concentrate in a 4 × 4 latin square were tested. the results indicated that by increasing the concentrate level in the diet of swamp...

This paper is an initial report on the mineral chemistry of four metamorphosed stratabound mineral deposits which are located within or adjacent to the Shuswap Complex. These are commonly referred t” as Cottonbelt, CK, Goldstream and Big I.edge deposits. Rock specimens were selected from those collected by Trygve H6y of the British Columbia Geological Survey Branch. The particular specimens cho...

The crystal structures of yellow Cu3PS4 and of black Cu3SbS4 were refined from single crystal X-ray diffraction data. Cu3PS4 crystallizes orthorhombic in an ordered wurtzite superstructure type with the space group Pmn21 (no. 31), a 1⁄4 7.282(1) A, b 1⁄4 6.339(1) A, c 1⁄4 6.075(1) A, V 1⁄4 280.38(8) A3, and Z 1⁄4 2. The refinement converged to R 1⁄4 0.0276, and wR2 1⁄4 0.0710 for 737 unique ref...

Mineral forms in rhizosphere and bulk substrate were examined for selected plant species (Cardaminopsis arenosa, Calamagrostis epigeios, Deschampsia caespitosa, Festuca ovina, Silene vulgaris, Viola tricolor) growing spontaneously in the close vicinity of a tailings pond and in a zone of eolian transmission of waste particles. Samples of substrates and plant roots were taken from sites in the B...

Silver-bearing zinc-iron tetrahedrite-tennantite and freibergit fahlores approximating the simplified formula (Ag,Cu)m(Fe,Zn)2(As,Sb)4S~3 have been equilibrated with excess electrum (AuxAgl_~) and chalcopyrite + pyrite + iron-bearing sphalerite (CuFeS2 + FeS2 + Fe0.05Zn0.95S) in evacuated silica tubes at 300 ~ in reversed silver-copper exchange experiments with less than 0.1 mg NH4CI added as a...
