In order to evaluation the effects of mycorrhiza, plant growth promoting rhizobacteria and nano zinc oxide foliar application on effective traits at grain filing of triticale under soil salinity condition, a factorial experiment was conducted based on randomized complete block design with three replications in research greenhouse of Faculty of Agriculture Sciences, University of Mohaghegh Ardab...
effect of concentration parameters on recovery of zinc oxidized minerals from lead flotation tailings of dandy mineral processing plant in north-western iran was studied. a sulfidization-flotation method has been used on a laboratory scale to investigate the effect of various reagents such as sodium sulfide as sulfidizing agent, primary amine as collector, dispersants and flocculants with diffe...
In agricultural cropping systems, crop residues are sources of organic carbon (C), an important factor influencing denitrification. The effects of red clover, soybean, and barley plant residues and of glucose on denitrifier abundance, denitrification gene mRNA levels, nitrous oxide (N(2)O) emissions, and denitrification rates were quantified in anoxic soil microcosms for 72 h. nosZ gene abundan...
A novel staphylolytic enzyme, ALE-1, is a glycylglycine endopeptidase produced by Staphylococcus capitis EPK1. ALE-1 possesses seven histidines. Chemical modification studies using diethylpyrocarbonate and iodoacetic acid suggested that a histidine or tyrosine residue(s) in the molecule is important for the organism's staphylolytic activity. All of the histidine residues, one tyrosine, and one ...
The UBR-box is a 70-residue zinc finger domain present in the UBR family of E3 ubiquitin ligases that directly binds N-terminal degradation signals in substrate proteins. UBR6, also called FBXO11, is an UBR-box containing E3 ubiquitin ligase that does not bind N-terminal signals. Here, we present the crystal structure of the UBR-box domain from human UBR6. The dimeric crystal structure reveals ...
The industrial solid waste recycling team at North Minzu University has done much research on resource utilization of magnesium slag. This chapter mainly introduces a discussion includes the use slag to prepare glass ceramics, porous and sulfoaluminate cement clinker, fixing/stabilizing heavy metals in acidic residue generated by lead-zinc smelting, modifying copper
Lead and zinc production is one of the main predisposing factors of excessive greenhouse gases emissions, air pollution and water consumption. In this paper, the environmental problems of lead and zinc production in Calcimin plant are expressed and life cycle assessment of this plant is assessed. The data regarding the amount of induced global warming and pollution, acidification, and depletion...
High-efficiency dechlorination processes are crucial for the clean utilization of CuCl waste residue from zinc hydrometallurgical processes. A new method oxygen-enriched microwave roasting has been proposed to improve process. The cavity perturbation was used in this paper measure permittivity a at various temperatures and apparent densities. results show that temperature had more significant e...
Bone morphogenetic protein (BMP)-1, which belongs to the tolloid subgroup of astacin-like zinc metalloproteinases, cleaves the C-propeptides of procollagen at the physiologic site and is, therefore, a procollagen C-proteinase (PCP). Cleavage occurs between a specific alanine or glycine residue (depending on the procollagen chain) and an invariant aspartic acid residue in each of the three chain...
