Imaging of chlorophyll a fluorescence (CFI) represents an easy, precise, fast and non-invasive technique that can be successfully used for discriminating plant response to phytotoxic stress with reproducible results and without damaging the plants. The spatio-temporal analyses of the fluorescence images can give information about damage evolution, secondary effects and plant defense response. In the last years, some studies about plant natural compounds-induced phytotoxicity have introduced imaging techniques to measure fluorescence, although the analysis of the image as a whole is often missed. In this paper we, therefore, evaluated the advantages of monitoring fluorescence images, presenting the physiological interpretation of different possible combinations of the most relevant parameters linked to fluorescence emission and the images obtained.

Detection Of Stress

Stress has become a common thing in today’s life. Because of the fast pace, it is a top health concern. Psychologists say that if they don’t learn healthy ways to manage stress now, it could have serious long-term health implications, such as depression, anxiety, high blood pressure, diabetes. Currently people are suffering from stress issues everywhere. Since last few decades stress has been detected in most of the people and there has been recorded severely increasing effect of stress on human body. Stress can alter complete health which leads to reducing the tolerating power of the human. In metro cities this condition is more severe. Hence it is necessary to identify stress before it causes any serious harm and treat on it. In this project we are presenting stress detection technique and lower it with the help of Music therapy. As there are many benefits of music so by taking advantage of it we are minimizing stress level to normal state. Detection of stress using brainwaves is a non-invasive method. We have selected 42 students who were about to go for their exam. Firstly we have recorded brainwaves before they were going to exam, then immediately after finishing their exam we have recorded brainwaves lastly they were allowed to listen to their favorite music and then recorded their brainwaves. From analysis it is clear that stressed brainwave were reduced to 29% by listening music.

Three Dimensional Images

We have developed a new X-ray microscope which produces complete three dimensional images of samples. The microscope operates by performing X-ray tomography with unprecedented resolution. Tomography is a non-invasive imaging technique that creates maps of the internal structure of samples from measurement of the attenuation of penetrating radiation. As conventionally practiced in medical Computed Tomography (CT), radiologists produce maps of bone and tissue structure in several planar sections that reveal features with 1mm resolution and 1% contrast. Microtomography extends the capability of CT in several ways. First, the resolution which approaches one micron, is one thousand times higher than that of the medical CT. Second, our approach acquires and analyses the data in a panoramic imaging format that directly produces three-dimensional maps in a series of contiguous stacked planes. Typical maps available today consist of three hundred planar sections each containing 512x512 pixels. Finally, and perhaps of most import scientifically, microtomography using a synchrotron X-ray source, allows us to generate maps of individual element.
