in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

the root pulling force as well as the amount of transferred soil have not been reported quantitatively for various sugar beet types. this study was designed to measure the amounts of transferred soil from farm and estimate the root pulling force among sugar beets populations with different root shapes at harvest time. the experiment was conducted as a split plot with a randomized complete block...

a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...

abstract plant species differ in their ability to grow at low available p soils in other words, plant species differ in p use efficiency at low p supply. this ability can be investigated by comparing p uptake efficiency of plants and relative effective factors. a pot experiment was carried out in the growth chamber and sugar beet, maize and groundnut were grown in a low available p soil in a co...

Salt tolerance of higher plants is determined by a complex set of traits, the timing and rate of evolution of which are largely unknown. We compared the salt tolerance of cultivars of sugar beet and their ancestor, sea beet, in hydroponic studies and evaluated whether traditional domestication and more recent breeding have changed salt tolerance of the cultivars relative to their ancestor. Our ...

Sugar and fodder beet were grown in three years to assess the potential sugar yield for ethanol production in the region. Fresh weight root yields ranged from 70-85 t/ha for sugar beet and 55-136 t/ha for fodder beet. Sugar contents averaged 15% for sugar beet and 10117o for fodder beet resulting in sugar yields of 10-12 t/ha and 5-12 t/ha respectively. Consistently higher sugar yield from suga...

the sugar beet plant has a conical-shaped root and at harvest the tap-root breaks which remains in the soil. as a result, a significant amount of root yield and consequently sugar content is lost. furthermore, the field soil remains in the root fissures and is carried with the root to sugar factory. in rhizomania and nematode-infested areas, the soil movement causes the disease wide spread. in ...

nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...

The thermostable enzyme systems produced by the thermophilic ascomycete fungus Talaromyces emersonii cultivated on various carbon sources were investigated for the production of high value products from sugar beet. A broad range of enzymatic activities relevant to cellulose, hemicellulose, and pectin hydrolysis were identified in T. emersonii culture filtrates. In hydrolysis experiments conduct...

BACKGROUND Enzymatic degradation of plant biomass requires a complex mixture of many different enzymes. Like most fungi, thermophilic Myceliophthora species therefore have a large set of enzymes targeting different linkages in plant polysaccharides. The majority of these enzymes have not been functionally characterized, and their role in plant biomass degradation is unknown. The biotechnologica...
