Abstract:

The feasibility of FTIR-based spectroscopy as a tool to measure cellular response to therapeutics was investigated. Fourier transform mid-infrared spectroscopy has been used in conjunction with multivariate analysis (MVA) to assess the chemistry of many clinically relevant biological materials; however, the technique has not yet found its place in a clinical setting. One issue that has held the technique back is due to the spectral distortions caused by resonant Mie scattering (RMieS), which affects the ability to confidently assign molecular assignments to the spectral signals from biomateria

Abstract:

Fourier transform near-infrared (FT-NIR) spectroscopy was investigated as a means of quantitative analysis of edible fats and oils. Initially, a method of simultaneously determining the cis and trans content, iodine value and saponification number of neat fats and oils using a heated transmission flow cell was developed. Two partial least squares (PLS) calibrations were devised, a process-specific calibration based on hydrogenated soybean oil and a more generalized calibration based on many oil types, the latter able to analyze oils from a variety of sources accurately and reproducibly.

Fourier transform infrared (FTIR) spectroscopy was employed to monitor the oxidation of edible oils in the absence and presence of antioxidants. Three synthetic antioxidants (butylated hydroxyanisole, propyl gallate and tert-butylhydroxyquinone) were added to menhaden oil at three different concentrations (1%, 0.1%, and 0.01%), and the FTIR spectra of the oils under conditions of oxidative stress were recorded as a function of time. The efficacy of each antioxidant was assessed by monitoring bands at 3444 cm$ sp{-1}$, characteristic of hydroperoxide formation, 971 cm$ sp{-1}$ for trans double

This work describes an investigation of the development of a Fourier Transform Infrared (FTIR) spectroscopic method for the determination of Solid Fat Index (SFI) of fats as a possible replacement of the traditional dilatometric procedure. The initial approach considered was the use of an existing FTIR analytical package which was designed to measure iodine value (IV), saponification number (SN), and cis and trans content. It was hypothesized that these measures could be related to SFI using multiple linear regression (MLR), thereby allowing the existing analytical package to simultaneously ma

Abstract:

<p> Compositional analysis of reservoir rock is a vital aspect of oil exploration and production activities. In a broad sense, knowing the mineral composition of a reservoir can help with characterization and interpretation of depositional environments. On a smaller scale, identifying mineralogy helps calibrate well logs, identify formations, design drilling and completion programs, and screen for intervals with potential problem minerals, such as swelling clays. The petroleum industry utilizes two main methods to find compositional mineralogy, x-ray diffraction (XRD) and thin section analysis

New Fourier transform infrared (FTIR) approaches for the quantitative determination of peroxide value (PV) and isolated trans analyses were investigated and developed.

A reference transmission cell (100 mum) method was developed based on the use of a unique TPPO absorption at 542 cm-1.

DSC studies indicated that the thermal stability of Con A is enhanced in the presence of salts, sugars and by pH.

Fourier transform infrared spectroscopy (FTIR) has applications in many areas of forensic science. The ability to produce information rich spectra is of particular use for the characterisation and discrimination of materials.

However, the production of information rich spectra requires suitable statistical tools for analysis, with multivariate analysis often used.

Abstract:

Mestrado em Biomedicina Molecular<br>Nowadays it is still difficult to perform an early and accurate diagnosis of dementia, therefore many research focus on the finding of new dementia biomarkers that can aid in that purpose. So scientists try to find a noninvasive, rapid, and relatively inexpensive procedures for early diagnosis purpose. Several studies demonstrated that the utilization of spectroscopic techniques, such as Fourier Transform Infrared Spectroscopy (FTIR) and Raman spectroscopy could be an useful and accurate procedure to diagnose dementia. As several biochemical mechanisms rela

A Espectroscopia FT-IR fornece informações moleculares através de fenômenos ópticos observado pela vibração de suas moléculas. Tem sido empregada em estudos biológicos para a caracterização de alterações neoplásicas. No entanto, são escassos os estudos que

Abstract:

There are two contributions of this thesis. The first contribution, described in chapters one through six, involves studing the relationship between the protein packing structure of bacteriorhodopsin (bR) and its function as a proton pump. In 2002, a novel crystallization method published by Bowie and Farham resulted in an unusual antiparallel monomeric packing structure of bicelle bacteriorhodopsin (bcbR) crystals, the spectroscopic properties of which had not been studied. In this thesis, these bicelle bR crystals are investigated to better understand how the changes in the protein tertia

Abstract:

O objetivo deste estudo foi avaliar os métodos de espectroscopia Raman e espectroscopia de absorção de infravermelho (FTIR) na identificação da degradação do trans-1,4-poliisopreno de cones de guta-percha sem uso, e o comportamento do material após diferentes períodos decorridos de sua fabricação por testes de indentação de nanodureza (IHT). Para a análise, foram selecionadas 27 amostras de cones de guta-percha sem uso, de 5 marcas comerciais vendidas no mercado brasileiro, cedidas por Cirurgiões-dentistas. As amostras foram avaliadas através de espectroscopia Raman, com base no sinal da ligaç

Abstract:

The detennination of trade routes and social interactions has previously been undertaken using cultural records and archaeological trends. In many regions this infonnation is sparse or inconclusive. By provenancing materials such as the pigments used by Aboriginal artists the movement of materials in the past can be directly investigated. This study is an attempt to characterise and provenance the excavated pigments from Fem Cave, Chillagoe, Southeast Cape York Peninsula. Two techniques, Fourier transform infrared -photoacoustic spectroscopy and proton induced X-ray and gamma-ray emission sp
