the aim of this descriptive and analytical type of study was to investigate epidemiological characteristics of post partum blues in pregnant women referring to maternity clinics in hafiz and zeinabieh hospital. the sample consisted of 400 pregnant women in their third trimester who were visited these clinics over the sampling period. the data were collected through two questionnaires; the first...

A graph is 2-stratified if its vertex set is partitioned into two classes, where the vertices in one class are colored red and those in the other class are colored blue. Let F be a 2-stratified graph rooted at some blue vertex v. An F -coloring of a graph G is a red-blue coloring of the vertices of G in which every blue vertex v belongs to a copy of F rooted at v. The F -domination number γF (G...

?Blue waffle,? or ?blue waffle disease,? is many things, but real is not one of them. It is an urban legend, a myth, a tall tale, a rumor, a hoax, etc. about a fictional sexually transmitted infection [2] (STI). If you do an image search, you?ll find (fake) pictures of blue waffle on the Internet. The blue refers to one of the alleged symptoms, which Reader #2 pointed out, and waffle is slang f...

In this study, Nitrogen doped TiO2 photocatalysts were prepared by the sol gel method and physicochemical properties were characterized by X-ray diffraction (XRD), and scanning electron microscopy (SEM), photoluminescence, and energy dispersive X-ray spectroscopy (DRS) techniques. The XRD data indicated that the nanoparticles had the same crystals structures as the pure TiO2</su...

Hypocotyl phototropism of etiolated Arabidopsis seedlings is primarily mediated by the blue-light receptor kinase phototropin 1 (phot1). Phot1-mediated curvature to continuous unilateral blue light irradiation (0.5 μmol m(-2) s(-1)) is enhanced by overhead pre-treatment with red light (20 μmol m(-2) s(-1) for 15 min) through the action of phytochrome (phyA). Here, we show that pre-treatment wit...

The single particle hydrogenation of methylene blue over a Pd/SiO2 catalyst was monitored in droplet-microreactor, using red/green/blue optical microscopy.

A simple analytical procedure is proposed for simultaneous determination of three common dyes (Basic Blue 9, Brilliant Blue E-4BA, and Reactive Blue 2) in natural waters without prior separation of the solutes. A popular chemometric method, partial least squares regression PLS-1, was effectively applied for spectral resolution of a highly overlapping system. At the best modeling conditions, mea...

Plants have several blue-light receptors, which regulate different aspects of growth and development. Recent studies have identified three such receptors: cryptochrome 1, cryptochrome 2 and phototropin. Cryptochromes 1 and 2 are photolyase-like receptors that regulate hypocotyl growth and flowering time; phototropin mediates phototropism in response to blue light. In addition, phytochrome A has...

PURPOSE To compare visual performance in eyes with intraocular lenses (IOLs) that filter short-wave blue light versus contralateral eyes with IOLs that do not filter visible blue light. METHODS In this prospective, assessor-masked study that was conducted at five clinics in the US, eligible candidates were at least 12 months postimplantation of a control IOL and a contralateral IOL that filte...
