Quantitative imaging and spectroscopic technologies for microbiology.

Light microscopy has enabled the observation of the structure and organisation of biofilms. Typically, the contrast in an image obtained from light microscopy is given by the time-averaged intensity that is effective in visualising the overall structure. Technological advancements in light microscopy have led to the creation of techniques that not only provide a static intensity image of the biofilm, but also enable one to quantify various dynamic physicochemical properties of biomolecules in microbial biofilms.

Heating characteristics of antenna arrays used in microwave ablation: A theoretical parametric study.

A numerical study of the performance of antenna arrays used in microwave ablation (MWA) is carried out. Double-slot coaxial antennas in triangular and square configurations are studied. Clinical (healthy vs.

Antenna design and tissue parameters considerations for an improved modelling of microwave ablation in the liver.

Microwave ablation is a technique used in treating hepatocellular carcinoma, especially in cases where surgical removal is impossible. In the present study we are investigating the effects of design characteristics of a coaxial slot antenna (single- versus double-slot, slot-to-tip distance and slot size) on the ablation zone characteristics (dimensions and shape). The specific absorption rate field and the temperature rises are calculated for a variety of application times and powers.

Numerical modeling of heat and mass transfer in the human eye under millimeter wave exposure.

Human exposure to millimeter wave (MMW) radiation is expected to increase in the next several years. In this work, we present a thermal model of the human eye under MMW illumination. The model takes into account the fluid dynamics of the aqueous humor and predicts a frequency-dependent reversal of its flow that also depends on the incident power density.

Numerical model of heat transfer in the human eye with consideration of fluid dynamics of the aqueous humour.

In this work we present a new 3D numerical model for heat transfer in the human eye, which takes into account the aqueous humour flow in the anterior chamber. We show that consideration of this phenomenon in the calculations alters the temperature distribution on the corneal and lens surfaces, without, however, noticeably changing their absolute values. The most notable effect is that the coolest area of the cornea moves at a point of 2 mm inferior to its geometric centre.
