The present paper constitutes a review of the literature on young infants' chromatic discrimination capabilities. A series of early studies showed that infants as young as two months postnatal can make at least some chromatic discriminations between stationary, homogeneous fields of different wavelength compositions. Current studies of spatial and temporal contrast sensitivity functions (CSFs) ...

We present a method for segmenting 2D microscopy images of freshwater green microalgae. Our approach is based on a specialized level set method, leading to efficient and highly accurate algae segmentation. The level set formulation of our problem allows us to generate an algae’s boundary curve as the result of an evolving level curve, based on computed background and algae regions in a given im...

Arakelov theory for Riemann surfaces is based on two analytic invariants: the Green function and Faltings δ invariant. Both invariants are hard to compute and they are only known in a few cases (cf. [3],[1]). They are related by a formula of Faltings, which also involves the theta-function on the jacobian of the curve. In any case, it is an ineffective relation, because three of the four terms ...

Matcha green tea powder (MGTP) is made with finely ground green tea leaves that are rich in phytochemicals, most particularly catechins. Shortbread biscuits were enriched with MGTP and evaluated for consumer acceptability and potential functional health properties. Baking decreased the content of total catechins by 19% compared to dough, although epimerization increased the amount of (+)-galloc...

Microsurgical subinguinal varicocelectomy (MSV) is generally considered the gold standard nowadays in view of the lower risk of complications and recurrence. To achieve complete ligation of veins while preserving testicular artery (TA) during the procedure remains challenging despite the application of high power optical magnification and micro-Doppler ultrasonography. The use of intraoperative...

The Phenology of vegetation varies with climate and variability in phenology is a powerful measure of climate change. Remotely-sensed data can be used to produce phenology curves that capture ‘green-up’, maturity and senescence from local to global scales. These curves are usually produced with Normalised Difference Vegetation Index (NDVI) data but are notoriously noisy. The MERIS Terrestrial C...

THE analysis of colour defects and individual differences in normal colour vision requires an apparatus in which spectral stimuli are used. It should be possible to determine the following: (1) Relative luminous efficiency of spectral light (luminosity curve). (2) Threshold of wavelength discrimination in spectrum (hue discrimination curve). (3) Threshold of saturation discrimination in spectru...

the purpose of this study was to identify the effects of green brand image on the green brand equity in the customers of appliance dealer's representation and appliance dealers in the chain department stores of sanandaj. research variables selected from yushan chen (2010) study. a questionnaire was used to measure theses dimensions that have been confirmed by experts and had 24 indices. it...

A sensitive and selective kinetic-spectrophotometric method was developed for the determination of trace amounts of uric acid. The method is based on the inhibitory effect of uric acid on the oxidation of Janus Green by bromate in the presence of sulfuric acid. The reaction was followed spectrophotometrically by measuring the absorbance at 518 nm using the fixed-time method. Under optimum exper...
