Ductility Improvement of an AZ61 Magnesium Alloy through Two-Pass Submerged Friction Stir Processing
Friction stir processing (FSP) has been considered as a novel technique to refine the grain size and homogenize the microstructure of metallic materials. In this study, two-pass FSP was conducted under water to enhance the cooling rate during processing, and an AZ61 magnesium alloy with fine-grained and homogeneous microstructure was prepared through this method. Compared to the as-cast materia...
Sucrose synthase activity in rice is potentially yield limiting. This is because the carbon that forms starch enters the developing rice grain as sucrose and that sucrose must be broken down to form the precursors of starch. The enzyme that breaks down sucrose in the filling rice grain is sucrose synthase. Earlier research efforts on rice physiology indicated that endosperm sucrose-synthase act...
The hairy fungus beetle, Typhaea stercorea (L.), occurs frequently in stored grain, often in large numbers. Populations infesting stored barley in Minnesota, corn in South Carolina, and wheat in Florida were sampled by means of grain probe traps. Spatial distribution of the species was examined by contour analysis of trap catch. In South Carolina, corn was sampled at 2 locations over 2 storage ...
Abstract:In this study, an effort has been made to determine the influence of rotational speed of tool on themicrostructure and hardness values of friction stir welded 2024-T851 aluminum alloy. The microstructure of stir zonein the joints has been investigated. It was found that the particles such as Al6(CuFeMn) particles are broken up duringfriction stir welding, and the degree of break up of ...
It gives me great pleasure to deliver the keynote address at the Asian Bond Conference organised jointly by the Thai Bond Dealing Centre (Thai BDC), Fixed Income Money Market Dealers Association of India (FIMMDA) and Primary Dealers Association of India (PDAI). It is a matter of significance that some of the major self-regulatory organisations (SROs) in the debt markets of Asia have taken this ...
in order to study the gene actions and heritability of the physical and chemical characteristics associated with appearance and cooking quality of rice grain, generation mean analysis was performed using a cross between two iranian rice cultivars, deylamani and sepidroud, having different quality characters. seeds of the parental lines and f1, f2, bc1 and bc2 generations were grown in randomize...
an experiment with randomized complete block design with 3 replications was carried out in the rice research institute of iran, rasht, during 2008 to study the effect of supplement foliar application of nitrogen (5% n) and potassium (3% k2o) at different growth stages (maximum tillering stage, booting stage, and both of them) on grain quality and nitrogen efficiency of hybrid rice, c.v. bahar-1...
This work investigated the production of the fungi Isaria fumosorosea and Isaria farinosa in biphasic fermentation using agro-industrial products and residues. Combinations of natural liquid substrates, alternative to the complete medium and potato dextrose medium, were evaluated. The best liquid media were sugarcane molasses + rice broth, rice broth + yeast and sugarcane molasses + yeast + ric...
[1] Apatite He/He thermochronometry has the potential to constrain cooling histories for individual samples provided that several presently untested assumptions are valid. Here we simulate the sensitivity of He/He spectra to assumptions regarding geometric model, crystallographic anisotropy, broken grain terminations, parent nuclide zonation, and the accuracy of results obtained from analyses o...
Several physical and chemical attributes of rice were evaluated to determine which character would be best to use to assess multiple rice varieties for resistance to the lesser grain borer, Rhyzopertha dominica (F.). Laboratory tests were conducted on single varieties of long-, short-, and medium grain-rice to develop procedures and methodologies that could be used for large-scale screening stu...
