The electrochemical process of cuprous oxide production is by the anodic dissolution of copper in an alkaline concentrated sodium chloride solution. The initial chloride in the electrolyte cell provides a condition for the formation of cuprous chlorocomplex anions. In the end,the cuprous oxide is formed through the anions hydrolysis by the hydroxyl ions, which are generated in the cathodic reac...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
In recent years, a large part of the plowed rangelands has been abandoned due to the lack of economics, knowing such pastures and estimating plant production can play a significant role in their recovery. . It is usually difficult to investigate the changes in rangeand production due to interference in the access to the field and gathering field data. Considering the importance of determining p...
Oxidative stress caused by overproduction of free radicals or oxygenated radical species plays a major role in causing many diseases. The findings suggest the use of antioxidants as compounds to control the release of these radicals or directly prevent their formation. Therefore, antioxidants can be used as drugs to reduce or prevent oxidative stress. Herbal medicines are the basis of modern ph...
green plants have emerged as ideal platforms for production of recombinant vaccine during recent decades. various antigens relating to a large number of animal and human diseases have been studied in different plant species for production of recombinant vaccines. despite the unique advantages of plant systems as green factories for production of recombinant vaccines, there are some major hurdle...
The Taguchi design of experiments was used to test the relative importance of medium components and environmental factors on poly(β-hydroxybutyrate)(PHB) production by Ralstonia eutropha. The optimum condition was obtained as: fructose concentration, 15 g/L; C/N ratio, 7.4; agitation speed 200 rpm; culture time, 40 h; temperature, 25 ° C; seed age, 15 h. At optimu...
Pectobacterium carotovorum subsp. carotovorum is a well-known plant pathogen that causes severe soft rot disease in various crops, resulting in considerable economic loss. To identify pathogenicity-related factors, Chinese cabbage was inoculated with 5314 transposon mutants of P. carotovorum subsp. carotovorum Pcc21 derived using Tn5 transposon mutagenesis. A total of 35 reduced-virulence or av...
the nayband formation was measured and sampled in parvadeh area, southern tabas city. in this area, this formation has a thickness of 1410 m, dividing into four members, namely gelkan, bidestan, howz-e-sheikh and howz-e-khan. a total 573 samples were treated for palynological analysis, and only 120 samples were productive. a total of 57 miospore taxa and 11 plant macrofossil were encountered. b...
BACKGROUND Rhamnolipids are potent biosurfactants with high potential for industrial applications. However, rhamnolipids are currently produced with the opportunistic pathogen Pseudomonas aeruginosa during growth on hydrophobic substrates such as plant oils. The heterologous production of rhamnolipids entails two essential advantages: Disconnecting the rhamnolipid biosynthesis from the complex ...
this paper tries to determine an optimum condition for the flotation operation of the alborz-sharghi coal washing plant. for this purpose, a series of comprehensive experiments have been conducted on representative samples from feed of the flotation system of the plant. four operational variables such as the collector dosage (fuel oil), the frother dosages (mibc), the pulp density percent and t...
