Continuous irradiation of Mougeotia with linearly polarized green light (550 nanometers, 0.2 watt per square meter) induces a change in the orientation of its chloroplast from profile to face position, if the electrical vector of the green light is vibrating normal to the cell axis. This change is complete within 25 minutes of the onset of irradiation. In contrast, if the electrical vector of t...

in iran, more than 90% of raw materials including oils and oil seeds are provided through import. camelina sativa l. as an oilseed crop, belongs to brassicaceae family, has been shown in several experiments that need very little water and resistant to chilling injury than other plant oils, especially canola. this experiment was conducted at research station of campus of agriculture and natural ...

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...

abstract in order to investigate the response of two species of p. ovata and p. psyllium to water deficit. the experiment was conducted during 2009 growing seasons in the agriculture research station ferdowsi of mashhad. for this purpose a split plot experiment based on complete randomized block design with three replications was used. four irrigation levels (4000, 3000, 2000, 1000 m3/ha) alloc...
