The pinning effect of cerium inclusions in the austenite grain growth of SS400 steel at 1300 ◦C is investigated by using a semi-empirical-simulation. Firstly, steel samples containing cerium inclusions are prepared; then the properties of inclusions are determined using SEM. In situ observation of austenite grain growth is performed by LSCM, to determine the fitting parameters of the model such...

A 2-year experiment was conducted to ascertain the effects of exogenously applied plant growth regulators (PGR) on rice growth and yield attributes under high day (HDT) and high night temperature (HNT). Two rice cultivars (IR-64 and Huanghuazhan) were subjected to temperature treatments in controlled growth chambers and four different combinations of ascorbic acid (Vc), alpha-tocopherol (Ve), b...

The mechanisms of texture development were examined for BaTiO₃ and a (K,Na,Li)(Nb,Ta)O₃ solid solution made by the templated grain growth method, and compared with the mechanism in Bi0.5(Na,K)0.5TiO₃. The dominant mechanism was different in each material; grain boundary migration in BaTiO₃, solid state spreading in Bi0.5(Na,K)0.5TiO₃, and abnormal grain growth in the (K,Na,Li)(Nb,Ta)O₃ solid so...

Plant essential oils are potential food preservatives due to their inhibitory effects on bacterial and fungal growth. Antifungal activities of common thyme (Thymus vulgaris) essential oil were tested against endophytic fungi grown from wheat (Triticum aestivum) grain, molecularly identifi ed as Alternaria alternata, Alternaria infectoria, Aspergillus fl avus, Epicoccum nigrum and Fusarium poae....

in order to study physiological characteristics of rainfed bread wheat genotypes, an experiment was conducted with 20 genotypes in a randomized complete block design with 4 replications under rainfed and supplementary irrigation conditions. this experiment was carried out at the dryland agricultural research institute (dari) in maragheh during 2007-2008. to determine growth indices, sampling wa...

In 2005, Hell, Johansson and Meier submitted a stream cipher proposal named Grain v1 to the estream call for stream cipher proposals and it also became one estream finalists in the hardware category. The output function of Grain v1 connects its 160 bits internal state divided equally between an LFSR and an NFSR, using a non-linear filter function in a complex way. Over the last years many crypt...

Enhanced grain growth in ultra-thin yttria-doped-zirconia (YDZ) films synthesized under ultraviolet (UV) irradiation is reported. The mean grain size in UV-activated 7.5 mol % yttria doped zirconia films nearly 56 nm thick increased to 85 nm upon annealing in an oxygen-rich ambient at 900 C for one hour, while in thermally grown YDZ they grew only to ~15 nm under identical annealing conditions....

Pre-harvest prediction of winter wheat (Triticum aestivum L.) grain yield and/or protein could assist farmers in generating yield maps and reliable product marketing. This study was conducted to determine the relationship between spectral measurements (taken from Feekes growth stage 8 to physiological maturity) and grain yield and grain protein. Spectral measurements were taken using photodiode...
