According to the character of straw pellet fuel cold molding technology, the compressing process was modeled by Finite Element Modeling (FEM) structure analysis tools. This indicated the variation laws between the stress and the strain, and the influence of the structure parameters of the die on the stress and the strain. It’s concluded from the work that when the length-to-diameter ratio of th...
The elementary solutions basic to the azimuthally symmetric component of the radiationdensity vector are developed for a general model concerning the scattering of polarized light. ZusammenfassungDie ElementadSsungen, die die Basis der azimuthal symmetrischen Komponente desVektors der Strahlungsdichte bilden, werden hergeleitet fiir ein allgemeines Modell fiir dieStreuung vo...
there are many parameters that affect the sheet hydroforming process such as fluid pressure, material properties, interfacial friction between blank and tool surfaces, etc. in this paper, a fem-based taguchi method is used to determine the effects of forming parameters on the quality of part formability in the process of hydrodynamic deep drawing assisted by radial pressure. four important form...
Die Anzucht der Blaualge Anacystis nidulans erfolgte wie bereits beschrieben4. Die Messung der Photosynthese-Aktivität erfolgte in W a r b u r g Gefäßen in 0,1-m. Phosphatpuffer pn 8,0 und Algen mit einem Chlorophyllgehalt von 0,05 mg bei 30 ^C; die Alkyl-benzimidazole wurden in 0,1 ml Methanol zugegeben. Nach Äquilibrierung mit 8% COa/Luft wurde mit 45 000 Lux (Philips Attralux Lampen) belicht...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
abstract coontail (ceratophyllum demersum) and watermilfoil (myriophyllum spicatum) are current submersed weeds in many fresh waters of iran. the excessive growth of these plants causes the reduction in utilization of water resources and making some ecological and economical damages in these areas. the aim of this study was to determine the response of two submerged aquatic weeds of coontail an...
die direktreduktion von eisenerzen zu eisenschwamm mittels erdgas wird iiberall dort verwendet wo einmal die notwendtigen rohstoffe und besonders der metallurgische koks zu wirtschaftlischen bedingungen fehlen. andereseirs wiederum miissen erdgasrerven in geniigenden mengen und qualitat zu verfugung stehen, urn die direktredution mit gutem wirkungsgrad durchfuhren zu konnen. in dieser arbeit wi...
High speed and absence of a precise control over pressure distribution confine sheet Electromagnetic Forming into a die to simple shapes having shallow depth. It is possible to reach a higher depth by using a convex punch instead of a concave die. In this study, sheet Electromagnetic Forming on a punch and sheet Electromagnetic Forming into a die are investigated. The electromagnetic part of th...
