For aperture color 3 s stimuli, the four unique hues, and at times the four (equally-balanced) binary hues, were measured for: (1) adapting white color temperatures 2850, 3400, 5500, 6500 K; and (2) luminance (L) for 5 and 6 log L ranges (about 0.01-3200 cd/m2) in 3.2:1 L steps (viewed singly) for 1 subject per white, 3 log L in 10:1 steps for 6 subjects for white 6500 K, and 1 log L for 2-11 s...

Purpose To determine the differences in the retinal sensitivities obtained by microperimetry with a single cross or a circular fixation target in normal individuals. Methods Thirty-two eyes of 16 healthy volunteers (mean age 28.9±1.4 years, range 24-44 years) were studied. The retinal sensitivity of the central 0 degrees and of the mean central 2 degrees consisting of 8 points were determined...

OBJECTIVES To assess which socio-economic indicator best predicts overweight in the European Union: educational attainment, occupational class or household income. SETTING The prevalence of overweight is strongly related to socio-economic position. The relative importance of different socio-economic dimensions is uncertain, and might vary between countries. DESIGN AND SUBJECTS Cross-section...

OBJECTIVE National body fatness (BF) data for English South Asian and Black children use BMI, which provides inaccurate ethnic comparisons. BF levels and time trends in the English National Child Measurement Programme (NCMP) between 2007 and 2013 were assessed by using ethnic-specific adjusted BMI (aBMI) for South Asian and Black children. METHODS Analyses were based on 3,195,323 children age...

X-ray and electron di!raction have been used to determine the surface roughness parameters of thin "lms and thus evaluate roughness e!ects on magnetic properties. For self-a$ne roughness, the demagnetizing factor is in#uenced by the roughness exponent H, and is proportional to w/m2 with w being the RMS roughness amplitude and m being the lateral correlation length. Roughness anisotropy can ampl...

to assessment alfalfa cultivars research project this research has been fulfilled in 2011 at khouzestan agricultural and natural resource research center in southwest of ahwaz in khouzestan province (iran) by position 31º20′ n, 48º40′ e. at first section for evaluation wet forage yield cultivars such as “baghdadi”, “mesasersa”, “yazdi”, “bami”, “nikshahri”, “synthetic” (main factor) and two cut...

Heifer performance, diet composition, and forage composition were compared during rotational and continuous grazing of mixed pasture (alfalfa, tall fescue, orchardgrass). One hundred eighteen yearling heifers were used to compare the three grazing systems during 2 yr. Treatments included continuous (CONT), 6-paddock rotational (6-PADD), and 11-paddock rotational grazing (11-PADD). Rotational pa...
