Specifically, fiber Bragg gratings are finding uses in instrumentation applications such as seismology, [29] pressure sensors for extremely harsh environments, and as downhole sensors in oil and gas wells for measurement of the effects of external pressure, temperature, seismic vibrations and inline flow measurement. As such they offer a ...
The concept of addressed fiber Bragg structures was introduced in 2018 by Airat Sakhabutdinov [1] and developed in collaboration with his scientific adviser, Oleg Morozov. . The idea emerged from the earlier works of Morozov and his colleagues, [2] [3] where the double-frequency optical radiation from an electro-optic modulator was used for the definition of the FBG central wavelength based on ...
In contrast to the fiber Bragg gratings, LPFGs couple copropagating modes with close propagation constants; therefore, the period of such a grating can considerably exceed the wavelength of radiation propagating in the fiber. Because the period of an LPFG is much larger than the wavelength, LPFGs are relatively simple to manufacture.
Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
According to Mattei's own ideas however, every disease originates in the change of blood or of the lymphatic system or both, and remedies can therefore be mainly divided into two broad categories to be used in response to the dominant affected system. Mattei wrote that having obtained plant extracts, he was "able to determine in the liquid ...
There are so many potential health problems that can afflict the feet ? like ingrown toenails, bunions, blisters, and even gout.
Extracts of the plant are used to ease the symptoms of malaria. The boiled juice or a tea made from the leaves or the whole plant is taken to relieve fever and other symptoms. It is also used for dysentery, pain, and liver disorders. [143] A tea of the leaves is taken to help control diabetes in Peru and other areas. [144]
Plants can protect themselves from abiotic stress in many different ways, and most include a physical change in the plant’s morphology. Phenotypic plasticity is a plant’s ability to alter and adapt its morphology in response to the external environments to protect themselves against stress. [ 2 ]
