Chlorophyll extracted from celery using 50% v/v water – methyl alcohol as a solvent. By this method the concentration of chlorophyll was 22.6% with yellowish-green color. This solution showed strongly absorption at 400 – 210 nm and maximum was at the end of ultra-violet region. This absorption appeared in water, methyl alcohol, and acetone, but strongest absorption was in water. No emission spe...

The patient was a 56-year-old female. whole body has brown patches for 16 years. Dermatological examination: were observed on the trunk and lower limbs, with scattered hypomigmentation symmetrical distribution of skin lesions. Histopathology showed mild hyperkeratosis in epidermis, focal liquefaction degeneration basal layer, masses light red stained material dermal papilla, or small lymphocyte...

The composite of Graphite/PbTiO3 has been synthesized for photocatalyst and photo-electrocatalyst Methyl Orange (MO) Violet (MV) degradation using a visible light source. aims the research were to study influence pH solution, iradiation time kinetics MO MV photodegradation, voltage photoelectrodegradation MV. Composite was by sol-gel process with Titanium Tetraisopropoxide (TTIP) solution Pb(NO...

Presence of colour in water will make it unsuitable for human consumption. Textile industries have the major role in imparting colour in natural water bodies as their outlets are opened to them. These industries rely upon azo dyes as it impart brilliant colour to fabrics. But its presence in water bodies creates serious problems. Structure of an azo compound is a very important factor to be con...

The importance of colour-coded asthma treatment in patient education is well accepted. Traditionally, reliever medication inhalers are blue in colour and preventer inhalers brown. This custom is not always followed and the inconsistencies in the colour of inhalers create a lot of confusion. Marketing of the same medication in different colour inhalers and introduction of new drugs and combinati...

The gene (CcLcc2) encoding laccase from the basidiomycete Coprinopsis cinerea Okayama-7 #130 was synthesized by polymerase chain reaction-based two-step DNA synthesis, and heterologously expressed in Pichia pastoris. The recombinant protein was purified by ammonium sulphate precipitation and nickel nitrilotriacetic acid chromatography. The molecular mass of CcLcc2 was estimated to be 54 kDa by ...

Mycobacteria can tolerate relatively high concentrations of triphenylmethane dyes such as malachite green and methyl violet. To identify mycobacterial genes involved in the decolorization of malachite green, a transposon mutant library of Mycobacterium smegmatis mc2 155 was screened for mutants unable to decolorize this dye. One of the genes identified was MSMEG_5126, an orthologue of Mycobacte...

The design and characterization of a system for in situ Raman analysis of surfaces prepared by ion soft landing (SL) is described. The performance of the new high vacuum compatible, low cost, surface analysis capability is demonstrated with surface enhanced Raman spectroscopy (SERS) of surfaces prepared by soft landing of ions of crystal violet, Rhodamine 6G, methyl orange and copper phthalocya...

Manufacturing and use of synthetic dyes for fabric dyeing has become a massive industry. However their toxic nature has become a cause of concern. The dye industries release high content color effluents that are toxic and resistant to degradation by conventional methods. Accumulation of these dyes in water causes eutrophication reduces reoxygenation capacity and damage to the aquatic organisms ...

in this research we described the effective hamiltonian theory and applied this theory to the calculation of current-current (q1,2) and qcd penguin (q3,…,6) c quark decay rates. we calculated the decay rates of semileptonic and hadronic of charm quark in the effective hamiltonian theory. we investigated the decay rates of d meson decays according to spectator quark model (sqm) for the calculati...
