introduction: conventional technology of sugar production from sugar beet roots consists of the next subsequent steps: sugar beet slicing, thermal denaturation of the sliced beet roots followed by diffusion in hot water at 70–75 _c, purification of extracted juice by lime, concentration of purified juice and crystallization. the diffusion process is one of the most important steps that effect o...

equipment availability is necessary in the development of agriculture mechanization. crop thinning is one of the most important stages in row crop production which is laborious and costly. the objective of this project is design and construction of a row crop thinning machine. four main system units are plant sensors, ground sensors, control and thinning platforms. in this machine the unwanted ...

in order to help in the engineering design of rice harvesting machines, there is a need to have exact information concerning the physical and mechanical properties of rice stems. the cutting force for rice stems, therefore, was measured by designing and fabricating a static and dynamic shear test apparatus. the effects of moisture levels and the cross-sectional area of stem as well as the varie...

protection and the prevention of illegal departures national grape germplasm, as one of the most important assets of the country, requires identification of the commercial and native cultivars and registered them in the international centers. the present project was conducted in order to registration the most important grape cultivars of iran based on morphological and physiological traits in t...

In order to explore measuring accuracy of coded-structured-light 3D measurement system onto high reflectance surface of turbine blade, measuring error analysis, system parameter design and uncertainty evaluation were investigated. First, device parameters and azimuth parameters of analytic geometry model and projective geometry model of coded structured light system were analyzed and unified. S...

Fouling is an important performance degradation factor of axial flow compressor. Proper fouling sensitive parameter is crucial to more effectively monitor the fouling severity. Currently fouling level and cleaning necessity are judged by the decrease degree of thermodynamic performance parameter from macro point. But simulation research of NASA rotor 37 finds that tip clearance increase also ca...

Maize leaves have distinct tissues that serve specific purposes. The blade tilts back to photosynthesize and the sheath wraps around the stem to provide structural support and protect young leaves. At the junction between blade and sheath are the ligule and auricles, both of which are absent in the recessive liguleless1 (lg1) mutant. Using an antibody against LG1, we reveal LG1 accumulation at ...

The anatomy of leaves and inflorescence axes of Spathanthus (2 spp.), Rapatea (2 spp.), Cephalostemon (1 sp.), and Duckea (1 sp.) (Rapateoideae, Rapateaceae) was studied to identify useful characters for taxonomy. The cross-section shape of inflorescence axis differentiates the genera, while the cross-section shape and structure of leaf midrib has a specific value. The following characteristics...
