mandibular incisor extraction in carefully selected cases as an alternative option to four bicuspid extraction or non extraction treatment has been advocated. the purpose of this study was to determine the degree of improvement in occlusion in patients with bolton discrepancy treated by one lower incisor extraction using peer assessment rating index (par indexes).pre and post treatment dental c...

the aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. a 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. the dog was bitten by a snake nearly 4 months ago. a 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. in the left eye, posterior synechia was detected in the ...

pectin is used as gelatinizing agent in food industry. in this study pectin was extracted from five commercial sugar beet varieties namely: doroty, rasul, 7112, br1 and ic using pre-hydrolysis technique. experiments were conducted using factorial design to verify the effect of temperature, time, percentage of hcl and water requirements on the extraction rate of pectin. the qualitative factors o...

a chelating resin is prepared by condensation polymerization of aniline with formaldehyde andcharacterized by ft-ir, elemental analysis and studied for the preconcentration and determination of traceplatinum ion from environmental water sample using inductively coupled plasma-atomic emission spectroscopy(icp-aes). the optimum ph value for sorption of the metal ions was 5. the maximum adsorption...

styrene is an important constituent of widely used organic solvents in industries for production of various synthetic materials. the use of solid-phase extraction (spe) has grown and is a fertile technique of sample preparation as it provides better results than those produced by liquidliquid extraction. in this study, spe has been optimized, regarding sample ph, sample concentration, sample fl...

objective: in this study, the possibility of prenatal diagnosis of down syndrome with real-time pcr method was evaluated. in this context, optimization of a suitable method for purification of high quality dna from amniotic fluid samples was also considered. materials and methods: pregnant women who had the high risk of having babies with down syndrome were selected according to the biochemica...

On the basis of the term candidate extraction tools under development in the EU project TTC, we designed an application for German and English data that serves as a first evaluation of the approach and of the techniques for monolingual term candidate extraction used in the project. The application situation highlighted, among others, the need for tools to remove incomplete word sequences from m...

a simple and sensitive method has been developed for the preconcentration and determination of trace level of co(ii) using uv-vis spectrophotometry. β-cyclodextrin polymer modified with 1-(2-pyridylazo)-2-naphthol (pan) is used for the preconcentration of co(ii) from samples at ph 8.5. the polymer is synthesized and characterized using elemental analysis, ft-ir and sem analysis. the factors aff...

magnesium is extracted with a chloroform solution of n-p-tolyl-2- thenohydroxamic acid (pttha) from aqueous solution of ph 9.5 .mg-pttha complex is colourless and the colour is developed by adding quinalizarin into the extract. lmax and e of the complex are 590nm and 2.8´103 lmol -1cm-1respectively.most common  ions do not interfere in the determination of magnesium. the spectral characteristic...
