This paper deals with the study of the spectral components of Lamb waves generated in thin aluminium plate using pulsed Nd-YAG laser and detected using a He-Ne Laser Heterodyne interferometer. Laser generation of Lamb waves leads to simultaneous generation of various frequency component as well as multiple Lamb wave modes. The Lamb wave signals are successfully and comprehensively analyzed usin...
Aromatic plants and laser beam wavelength in the red range of visible spectra (623.8 nm), most commonly used for treating plant species, were selected. As there is not much information references, it necessary to set a scale with qualitative partially quantitative evaluations results. Specimens thyme seed (Thymus vulgaris) selected as aromatic studying effect low-power lasers on development, co...
In 100 healthy, adult and female mice weighing about 20 to 25 g each, paris of full thickness and nearly symmetrical cutaneous wounds, 100±15 mm² each were created in dorsolumbar region. Mice were divided into 3 groups randomly, group 1 (Right wound exposure), group 2 (Left wound exposure) and group 3 (Control). Wounds were exposed to laser He-Ne (632.8 were length and 16 mw constant power) for...
We demonstrate the generation of a coherent water window x ray by extending the plateau region of high-order harmonics under a neutral-medium condition. The maximum harmonic photon energies attained are 300 and 450 eV in Ne and He, respectively. Our proposed generation scheme, combining a 1.6 microm laser driver and a neutral Ne gas medium, is efficient and scalable in output yields of the wate...
relative diffuse reflection measurements from the original and ground surfaces using a he-ne laser are reported. the intensity measurements for the metallic, transparent dielectric, matte plastic surfaces and colored papers are presented. our results indicate that among metallic surfaces tested, aluminum has the highest diffuse reflectance; while the original stainless steel surface shows the l...
BACKGROUND & OBJECTIVES Oral mucositis is a common debilitating complication of radiotherapy occurring in about 60 per cent of cancer patients. Considerable buccal toxicity of radiotherapy or chemotherapy in cancer patients to become discouraged and can affect their quality of life. In addition, such toxicity can alter the treatment plan. At present, there is no clinically appropriate prophylax...
