This research has investigated the possibility of using two photoplethysmography (PPG) sensors to measure blood oxygen saturation and through this monitor a patient’s pulse at two sites; the ear and the finger. Using these two simultaneous and continuous measurements the ultimate aim is develop a method of monitoring blood pressure.

Blood pressure (BP) is an important and commonly used vital sign to monitor a patient’s health. Current methods for monitor blood pressure are unsuitable for continuous, uninterrupted measurement of blood pressure outside of a hospital setting as such methods are invasive and could pose risks if complications occur. This research has investigated the possibility of using two photoplethysmography (PPG) sensors to monitor a patient’s pulse at two sites; the ear and the finger.

Influence of substitution of 3d metals for Mn on properties of La0.67Ca0.33Mn0.9 TM0.1O3 (TM = Fe, Co, Ni) compounds was studied. Ferromagnetic – paramagnetic and metals – insulator transitions were significantly affected by Mn-site substitution. However, no observable difference was found in their crystal structure from X-ray diffraction analysis. At room temperature the structure characterization of these compounds gave the single phase and structure is the distortion orthorhombic cell with space group symmetry Pnma.

The general objective of this thesis is to develop a framework for transition of financial statements from Vietnamese Accounting Standard (VAS) to Intrenational Financial Reporting Standard (IFRS) for Vietnamese companies. It is necessary to identify and measure factors that affect in transition of IFRS financial statements in the conditions of economic, political, cultural and social of Vietnam.

With the aim to distinguish between local and global conformational changes induced by trifluoroethanol in RNase A, spectroscopic and activity measurements in combination with proteolysis by unspecific proteases have been exploited for probing structural transitions of RNase A as a function of trifluoroethanol concentration. At 30% (v/v) trifluoroethanol (pH 8.0; 25 °C), circular dichroism and fluorescence spectroscopy indicate a cooperative collapse of the tertiary structure of RNase A coinciding with the loss of its enzymatic activity....

A clear difference in the enthalpy changes derived from spectroscopic and calorimetric measurements has recently been shown. The exact interpretation of this deviation varied from study to study, but it was generally attributed to the non-two-state transition and heat capacity change. Although the temperature-dependent thermodynamics of the duplex formation was often implied, systemic and extensive studies have been lacking in universally assigning the appropriate thermodynamic parameter sets.

Important hydrogenbonding interactions between substrate OH-groups inyeasta-glucosidases andoligo-1,6-glucosidase from glycoside hydrolase family 13 have been identi®ed by measuring the rates of hydrolysis of methyla-isomaltoside and its seven monodeoxygenated analogs. The transition-state stabilization energy, DDGà, contributed by the indi-vidual OH-groups was calculated from the activities for the parent and the deoxy analogs, respectively, according toDDGà ˆ±RTln[(Vmax/Km)analog /(Vmax/Km) parent]....

The interaction of bacterial endotoxins [lipopolysaccharide (LPS) and the
endotoxic principle lipid A], with high-den-sity lipoprotein (HDL) from serum was investigated with a variety of physical techniques and biological assays. HDL exhibited an increase in the gel to liquid crystalline phase transition temperature Tc and a rigidification of the acyl chains of the endotoxins as measured by Fourier-transform infrared spectroscopy and differential scanningcalorimetry.

The catalytic activity of phenylalanine hydroxylase (PAH, phenylalanine 4-monooxygenase EC 1.14.16.1) is regulated by three main mechanisms, i.e. substrate (L-phenylalanine, L-Phe) activation, pterin cofactor inhibition and phos-phorylation of a single serine (Ser16) residue.To address the molecular basis for the inhibition by the natural cofactor (6R)-L-erythro-5,6,7,8-tetrahydrobiopterin, its effects on the recombinant tetrameric human enzyme (wt-hPAH) was studied using three different conformational probes, i.e.

The process of pressure-induced modification of horse liver alcohol dehydrogenase (HLADH) was followed by measuringin situ catalytic activity (up to 250 MPa), intrinsic fluorescence (0.1–600 MPa) and modifications of FTIR spectra (up to 1000 MPa). The tryptophan fluor-escence measurements and the kinetic data indicated that the pressure-induced denaturation of HLADH was a process involving several transitions and that the observed transient states have characteristic properties of molten globules. ...

The annual production of various polymers can be measured only in billion tons of which polyolefins alone figure around 100 million tons per year. In addition to radical and ionic polymerization, a large part of this huge amount is manufactured by coordination polymerization technology. The most important Ziegler-Natta, chromium- and metallocene-based catalysts, however, contain early transition metals which are too oxophilic to be used in aqueous media.
