The long healing time of bone after tooth extraction in order to construct artificial teeth is uncomfortable to the patient because of aesthetic or masticatory problems in addition to the daily visit to dental clinic. The objective of this study was to evaluate the effect of 805 nm diode laser with long time intervals on repair of bone and skin incisions in rabbits through biochemical, radiological and histological findings. Eighteen New-Zealand rabbits were undergone surgical operations to make a cavity in the bone of the lower jaw, the rabbits were divided into two groups:- Group A (control group) containing nine rabbits. Group B (lased group) containing nine rabbits in which two cavities were done, one on the right side and the other on the left side of the mandible. The cavities were subdivided into two groups according to the exposure time. Group B1 (the right side) which was underwent treatment with 805 nm continuous diode laser with output power of 900mW and exposure time of 5 min, every 72 h for two weeks. Group B2 (the left side) which was underwent treatment with 805 nm continuous diode laser with output power of 900mW and exposure time of 10 min, every 72 h for two weeks. The diode laser with a wavelength of 805 nm, power 900 mW and operating on continuous mode was applied directly over the site of the cavity according to the group. Radiological findings, histological and biochemical evaluations for both bone and skin were done for all groups after 7, 14 and 28 days of follow up. The histological results showed that there was a complete wound healing and bone repair at day 28 postoperatively in sub group B2 which is represented by the group treated with 805 nm diode laser with exposure time of 10 min, every 72 hours. In conclusion, the 805 nm continuous wave diode laser with power density of 1.79 W/cm2 and exposure time of 10 min, every 72 h for two weeks was beneficial to stimulate healing in bone and skin.

- baumannii is an aerobic gram negative coccobacilli, it is considered multidrug resistance pathogen (MDR) and causes several infections that are difficult to treat. This study is aims to employ physical methods in sterilization and inactivation of A. baumannii, as an alternative way to reduce the using of drugs and antibiotics.
Cold Atmospheric Plasma was generated by one electrode at 20KV, 4 power supply and distance between electrode and sample was fixed on 1mm. A. baumannii (ATCC 19704 and HHR1) were exposed to Dielectric Barrier Discharge type of Cold Atmospheric Plasma (DBD-CAP) for several periods

Fiber Bragg Grating has many advantages where it can be used as a temperature sensor, pressure sensor or even as a refractive index sensor. Designing each of this fiber Bragg grating sensors should include some requirements. Fiber Bragg grating refractive index sensor is a very important application. In order to increase the sensing ability of fiber Bragg gratings, many methods were followed. In our proposed work, the fiber Bragg grating was written in a D-shaped optical fiber by using a phase mask method with KrFexcimer. The resultant fiber Bragg grating has a high reflectivity 99.99% with a Bragg wavelength of 1551.2 nm as a best result obtained from a phase mask with a grating period of 1057 nm. In this work it was found that the rota

In this work, we are obviously interested in a general solution for the calculation of the image of a single bar in partially coherent illumination. The solution is based on the theory of Hopkins for the formation of images in optical instruments in which it was shown that for all practical cases, the illumination of the object may be considered as due to a self – luminous source placed at the exit pupil of the condenser , and the diffraction integral describing the intensity distribution in the image of a single bar – as an object with half – width (U0 = 8 ) and circular aperture geometry is viewed , which by suitable choice of the coherence parameters (S=0.25,1.0.4.0) can be fitted to the observed distribution in various types of mi
