abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
abstract isolates of rhizoctonia spp., obtained from sugar beet roots and crowns with dry rot symptoms that had been collected from various sugar beet production regions in khorasan razavi province during 2008 and 2009, were investigated in this research. characterization by conventional techniques and molecular methods using species-specific primers was carried out. results showed that from 36...
The rapid population growth and the need for more agricultural production necessitate more attention to water shortage and enhancing water productivity. To assess water productivity and supply:demand ratio index in sugar beet, this experiment was carried out using SUCROS growth simulation model. Long-term climatic data and collecting questionnaires from farmers were used to assessing water prod...
Sugar beet is one of the most important agricultural crops and its yield depends on irrigation water. Due to the impossibility of assessing the effect of all water amount strategies on sugar beet yield, it is necessary to use crop models such as WOFOST, AquaCrop and Cropsyst. In order to achieve this goal, a set of data collected from Shahrekord’s Agricultural Research Station were used. Treatm...
the objectives of this study were to determine the energy use efficiency and economical potential of sugar beet production in miandoab city, west azerbaijan province in 2011-12. fields were classified into three groups as group i (less than 1 ha), group ii (1-2 ha), and group iii (more than 2 ha). inputs and outputs data were collected from growers using questionnaire and interview methods. res...
We revisit the cost of the U.S. sugar program by analyzing the welfare implications of its removal. We use a multimarket model of U.S. sweetener markets, which includes raw crops, sugar extraction and refining, high-fructose corn syrup, and sweetener users (food-processing industries and final consumers). Our approach addresses the industrial organization of food industries using sweeteners and...
Sugar beet (Beta vulgaris) is a biennial plant that requires a cold period in order to induce flowering, a process called vernalization. The period of vernalization required to induce flowering can vary by genotype (between 90-120 days). Holding beets in cold storage (4C) at high humidity (95%) is expensive and labor intensive, requiring specialized equipment and multiple fungicide applications...
The energy efficiency, greenhouse gas (GHG) emissions, and carbon efficiency of paddy rice production were analysed in Sari in the Mazandaran province of Iran during 2011–2012. Data was collected through questionnaires and interviews with paddy producers. The results showed that the net energy gain was 27,932 MJ ha-1 and energy efficiency was 1.83 during production. The results o...
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
in general, spring cultivation of sugar beet is prevalent, but nowadays because of water sources limitation and also plants low water use efficiency in this time of cultivation, autumn cultivation is growing up. several assessments also have showed that in compare with spring cultivation, autumn cultivation of sugar beet has other benefits including reducing the likelihood of plant disease and ...
