Abstract The objective of this work was to analyze components variances and heritabilities, estimate selection gain, evaluate the different pressures for physical quality attributes grains families segregating generations irrigated rice (Oryza sativa), through REML/BLUP methodology. experiment conducted in state Rio Grande do Sul, Brazil, where selections were made F3, F4, F5 generations, 2015/...
The effect of mean gloss level on perceived whiteness was evaluated by magnitude estimation and pair wise comparison of papers with varying shades and gloss levels. The samples were printed on substrates of different gloss to target L*a*b* values measured under a light booth illumination having a 5000 K correlated colour temperature. Observers were able to rate the whiteness of the samples with...
the subjects of the study are only the tefl teachers and students at gilan university. to obtain the desired data, a questionnaire which was based on the theories and disecussions gathered, was used as the main data gathering instrument. to determine the degree of relationship between variables, covariance and pearson product moment correlation coefficient were the formulas applied. the data we...
since esp received universal attention to smooth the path for academic studies and productions, a great deal of research and studies have been directed towards this area. swales’ (1990) model of ra introduction move analysis has served a pioneering role of guiding many relevant studies and has proven to be productive in terms of helpful guidelines that are the outcome of voluminous productions ...
abstract this research has been carried out with the purpose of investigating the conditions and related elements of the employment of the educational sciences graduates of hamedan province universities in 1382-1387 academic years. it has been a descriptive research of a correlation kind, and the population number has been 1180 grduates of payam- e noor universites in asad – abaad, kaboudaraha...
This thesis is about modelling and predicting the perceived whiteness of plain paper from the paper composition, including fluorescent whitening agents. This includes psycho-physical modelling of perceivedwhiteness frommeasurable light reflectance properties, and physical modelling of light scattering and fluorescence from the paper composition. Existing models are first tested and improvements...
this research has been taken among the students of high school in karaj city during the years 1391 and 1392. this is a survey research and data gathering is through questionnaires. studying the “an analysis of students’ tendency toward non-native reference groups in karaj”. the questionnaire was distributed among 260 of these students who were chosen through multi step cluster sampling. conside...
grain discoloration caused by fungi agents, in crop season that the mature grain stage coincides with rain, it causes many damages. in this research effect of paddy discoloration of three varieties (hashemi, gohar and khazar) and disease index in two levels (high and low disease index levels) on grain apparent quality, milling properties and grain bending strength was investigated in a factoria...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
The field of whiteness studies is relatively young compared to other well-established disciplines, including critical race theory. On its trajectory to carve out a new academic niche, whiteness studies is challenged with, and must therefore negotiate, a wide range of criticisms intended to dismantle the enterprise. This synthesis paper inspects the literature on whiteness as an analytical conce...
