Green mesoporous SBA-15 was synthesized by using corn stack ash (CSA), a new renewable silica source, as the main raw material. 80 wt% sodium silicate solution from CSA mixed with tetraethyl orthosilicate (TEOS) solution, and fi nally after hydrothermal process, SBA- 15 obtained. Subsequently, iron metal incorporated into prepared used an effi cient Fenton catalyst for degradation of indigo car...

Carbon Expo boasts around 3,000 participants from over 100 countries. According to a recent survey, they and their colleagues earn an average salary of $79,000. A quarter of them earned over $100,000 in 2010. The 250 or so exhibitors at Carbon Expo include blue chip financial institutions like Barclays Capital and JP Morgan as well as specialized brokers, project developers and investment bouti...

Using 24 observers with normal color vision, perceived shifts in hue were determined for a yellow-red, green, and blue-green at intermittencies of 5, 10, and 20 cps. The hue shift for yellow-red was consistent with the hue shift exhibited by a deuteranomalous observer while the hue shift for green and blue-green was consistent with that exhibited by a protanomalous observer.

Based on ab initio density functional calculations, we propose γ-P and δ-P as two additional stable structural phases of layered phosphorus besides the layered α-P (black) and β-P (blue) phosphorus allotropes. Monolayers of some of these allotropes have a wide band gap, whereas others, including γ-P, show a metal-insulator transition caused by in-layer strain or changing the number of layers. A...

We investigated whether people who report different colors for #thedress do so because they have different assumptions about the illumination in #thedress scene. We introduced a spherical illumination probe (Koenderink, Pont, van Doorn, Kappers, & Todd, 2007) into the original photograph, placed in fore-, or background of the scene and-for each location-let observers manipulate the probe's chro...

The law and the economy are deeply influenced by horizontal property rights, which are the rules regulating legal direct and indirect takings between private parties. To foster research on the determinants and impact of these institutions, we illustrate here a novel data set partially employed in (Dari-Mattiacci, Giuseppe, Carmine Guerriero, 2015; Dari-Mattiacci, Giuseppe, Carmine Guerriero, Zh...

AIM To know the more detailed findings of the small intestinal mucosa with the use of a magnifying endoscope and a vital dye, and the efficacy of the both tools. PATIENT AND METHODS A 54-year old female patient with celiac disease. The duodenal mucosa downward as far as the descending portion was observed with a magnifying endoscope (Olympus GIF HM) before and after spraying the mucosa with 0...

A 65−year−old man was referred to our de− partment for polypectomy. A polyp, 20 mm in diameter, was found in the as− cending colon on colonoscopy (Figure1 a). The polyp surface was covered by charac− teristic multiple dimples, long thin ves− sels, and mucus. Chromoendoscopy with 0.4% indigo carmine enhanced the ap− pearance of the polyp surface dimples, and subsequent magnification revealed a t...

The presence of polyhydramnios and oligohydramnios is pathognomonic for twin-twin transfusion syndrome (TTTS). However, polyhydramnios of both twins can exist in TTTS in the setting of a septostomy of the dividing membrane. In prior reported cases of dual polyhydramnios TTTS, the septostomy was identified through either ultrasound or fetoscopy thus helping to establish the diagnosis of TTTS wit...
