Styrene (St, 99%) and methyl methacrylate (MMA, 99%) were obtained from Aldrich company. These monomers were first dried over calcium hydride, were purified by being passed through a column of basic alumina, and were distilled under reduced pressure. Ethyl 2-bromoisobutyrate (EBIB, 98%), copper (I) bromide (CuBr, 99%), copper (I) chloride (CuCl, 99%), and other chemical reagents were procured from Aldrich company and used as received. N-methylbis[2-(dodecylthio)ethyl]amine (SNS) was synthesized…

at 280 nm for BSA changes linearly between 100 and 200μM and becomes non-linear with increasing BSA concentration. This indicates severe concentration dependent changes in the optical properties of the protein. This could be due to either the refractive index changes in the sample or possible dimerization/aggregation. This change should be considered when performing the fluorescence analysis. This implies that the fluorescence titrations up to 200μM are well behaved i.e. linear. The experiment…

urine of rats and human while GC-FID [19] was used for MNT analysis in human urine. Also, MNT in mixture with other drugs have been assayed in human plasma using GC-FID [20]. In pharmaceutical preparations, MNT has been assayed using HPLC with refractive index detector [21], with ultra-violet (UV) detection [22], with UV detection after chromogenic derivatization [23] and with polarized photometric detection [24]. Other methods used for analysis of MNT are HPTLC [25] and spectrophotometric color…

Diffuse Optical Tomography is non invasive, non ionizing functional imaging modality used for detection of brain tumor and breast cancer. A forward model design depicts the placement of laser source and photo-detector around the tissue boundary. The light propagation on the phantom takes place in Near-Infra-Red wavelength. The incident light on the tissue boundary was absorbed and scattered. The scattered rays are detected by the photo-detector and scattered voltage of the tissue was measured.…

there will be a range of light wavelengths present. These wavelengths travel at different speeds than the others. This causes the waveforms to distort and causes errors in reading the signal in the other end of the cable. (Sheldon T. 2001) The graded-index cable is designed to minimize the delay of the slower…

Discussion The results of this experiment for the hypotonic treatment group did support the tested hypothesis that urine production rate should increase, while salt concentration and specific gravity of urine should decrease for this group. For the isotonic treatment group, the tested hypothesis was supported in that the specific gravity and salt concentration went up slightly, but was not supported in that the the urine production rate did not greatly increase over time. The findings for the…

CHAPTER 1 TIN OXIDE 1.1 Introduction Tin dioxide, also known by the systematic name tin(IV) oxide and stannic oxide in the older notation, is the inorganic compound with the formula SnO2. The mineral form of SnO2 is called cassiterite, and this is the main ore of tin. With many other names, this oxide of tin is the most important raw material in tin chemistry. This colorless, diamagnetic solid is amphoteric. 1.2 Structure It crystallises with the rutile structure, wherein the tin atoms are six…

background relative to the overall background intensity. C. What is the purpose of immersion oil? Why does it work? The purpose of immersion oil is to increase the resolution of a microscope. Immersion oil works well because it has almost the same refractive index as the glass slide; therefore, the refraction of light entering the lens becomes minimal and gives a better view of the specimen under the microscope. Exercise 2: Observing Bacteria Cultures in Yogurt A. Describe your…
