The objective of this study was to evaluate the dynamics of tocopherols in cotyledons and radicles from sunflower seeds with high and low total tocopherol content, mainly in the α-tocopherol form, and from seeds with increased proportions of β-, γ-, and δ-tocopherol, both under dark and light conditions. Tocopherol content was measured every 24 h from 1 to 12 days after sowing. In all cases, th...
Three potato cultivars (Solanum tuberosum L.), spring Marfona, autumn Cosima and Marfona, obtained from Isfahan Province, were stored under different conditions: 4oC, darkness 12oC, fluorescent light room temperature, darkness and room temperature, daylight. Relative humidity of the above stores was 85 to 90%. Analyses were carried out to determine total glycoalkaloids, α-solanine, specific gra...

introduction: lasers, light emitting diodes (leds) and super luminous diodes (slds) are widely used to treat selected musculoskeletal, integumentary and neurological conditions. the mechanisms underlying the reported treatment effects of light therapy are unclear and the physiologic effect of light on a variety of tissues, particularly neurological, is mostly unknown. a few researchers have rep...
light is never being distributed homogeneously and it forms a gradient over biomass. the unidirectional nature of light gives rise to a vertical gradient of light intensity as a function of depth. the maximum depth of the light zone suitable for phytoplankton photosynthesis is designated as the euphotic depth. this study was designed to test the hypothesis of mixing depth of phytoplankton and i...
ce memoire presente une etude du theme de la solitude de lhomme dans trois oeuvres noires de jean anouilh: antigone, la sauvage, le voyageur sans bagage. lobjectif est dexpliquer les approches de jean anouilh sur les conditions sociales de lhomme daujourdhui qui se revelent par le theme de la solitude. cette etude comprend cinq chapitres: le premier explique la solitude volontaire et egalement ...
this study investigates the problem of translating religious allusions in persian literature, namely the ones borrowed from quranic verses and hadiths. the purpose of this study is to shed light on how different translators dealt with such a task and also to provide guidelines for translators in coping with religious allusions.
in this study the factors controlling the software colorimetry (photoshop), including illumination (direct and indirect), image background (white and black), camera settings (zoom, light, resolution and environmental conditions) and the conversion equations of r, g, b images to l *, a *, b *, compared with the results of the device were investigated and optimized. the results showed that the fa...
Shade is a widespread issue for turf areas that reduces quality, and the lack of light to drive photosynthetic processes one major factor responsible these declines. Maintaining positive carbon balance essential plant survival under low-light conditions, but large-scale screening performance can be difficult task. Chlorophyll fluorescence rapid curves (RLC) were used understand difference in hy...
