Pressure measurement

Hypertension is the leading disease in Vietnam and the leading risk factor for noncommunicable diseases worldwide. It is a manageable and treatable condition, according to the guidelines of the Ministry of Health and the clinical practice recommendations of the Vietnam Society of Cardiovascular and the Vietnam Society of Hypertension.

The primary objective of this work is to study the aerodynamic pressures on Mirror Surface at Various speeds to determine the effects of aerodynamics on to Mirror vibration. Additionally, the Mirror was modified by Shrouding around the external periphery to determine the possibility of minimisation of aerodynamic pressure fluctuations and thereby vibration. The Shrouding length used for the analysis was of 24mm, 34mm and 44mm length.

The objective of this thesis was to investigate the development of a micro-electromechanical system (MEMS) which can be implanted in the eye to provide continuous monitoring of glaucoma conditions. Current glaucoma monitoring involves taking laboratory based intra ocular pressure (IOP) measurements. The measurement of intraocular fluid flow and IOP parameters related to blockage formation in the eye require to be continuously monitored in Glaucoma.

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.

Ikkai&Ooi [Ikkai,T.&Ooi,T. (1966)Biochemistry5, 1551± 1560] made a thorough study of the e€ect of pressure on G- and F-actins. However, all of the measurements in their study were made after the release of pressure. In the present experiment in situ observations were attempted by using eATP to obtain further detailed kinetic and thermodynamic information about the behaviour of actin under pressure.

Small-angle neutron scattering experiments were performed on horse azidometmyoglobin (MbN3) at pressures up to 300 MPa.Other spectroscopic techniques have shown that a reorganization of the secondary structure and of the active site occur in this pressure range. The present measurements, performedusingvarious concentrations ofMbN3, showthat the compactness of the protein is not altered as the value of its radius of gyration remains constant up to 300 MPa.

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 information required for successful assembly of an icosahedral virus is encoded in the native conformation of the capsidproteinand in its interactionwith the nucleic acid. Here we investigated how the packing and stability of virus capsids are sensitive to single amino acid substitutions in the coat protein. Tryptophan fluorescence, bis-8-anilinonaph-thalene-1-sulfonate fluorescence, CD and light scattering were employed to measure urea- and pressure-induced effects on MS2 bacteriophage and temperature sensitive mutants. ...
