Abstract

The present study was done to determine and evaluate the effect of X-ray irradiation on the testicular tissue of rabbits those were exposed for a long time. Ten male rabbits, 8-9 months old and their weight approximately two kg. Rabbits were exposed to X-ray irradiation for two months/ twice daily. Blood parameters and testosterone hormone were measured within 20th, 40th, and 60th days after exposure. Orchictomy were done by surgical methods after 60th days for histopathological examination. The results revealed highly changes in testis such as atrophy, hyper atrophy, blood vessel congestion and suppression of spermatogenesis, blood parameter also changed and testosterone levels reach to zero at 60th days after exposure. In concluding that the persistence of X-ray exposure caused deterioration and passive effects on testicular tissue and other organs of rabbits.

Abstract

Foreign body can be defined as any matter that created out of scope of the body but inter the body due to injury, Plain radiograph, computed tomography scan ,magnetic resonance imaging and ultrasonography could be used to assess and localize the foreign body, In this case report we will explain a case of foreign body established in the maxillary sinus and how CT scan was useful in determine the position of this foreign body, the surgeon reported that computed tomography scan was useful in such cases, so it can be concluded that computed tomography scan can assess the size and shape of the precisely and can give the exact position of foreign body but the patient receive higher dose of radiation rather than the dose has been received from dental panoramic tomography.

Abstract

Third molars or wisdom teeth, as they are more commonly known, are the teeth which are most often missing, impacted and with altered morphology.The aim of this study is to evaluate third molars eruption circumstances which include number, angulation, level, and amount of room for eruption of wisdom teeth per subjects.A total of 300 subjects (150 male and 150 female students within the age group of 17-26 years were selected . Any case who had history of extraction of any of the third molars or who rejected to give approval for participation were excluded, for each subject, panoramic imaging were obtained. The Results showed that the level of occlusal plane of third molar similar to that of adjacent tooth was seen in (40.79%)in male and (51.94)in female, also the results showed that 3.3%of the third molars were congenitally missing, and nearby (90.3%) of the students had all four third molars.0.66%had one third molars and 2%had two third molars, third molar agenesis showed no difference between male and female. Angulations position was maximum with vertical position in maxilla (73.45%) and mesio-angular position in mandible (41.6%) level of occlusal plane of third molar similar to that of adjacent tooth was seen in (45.8.%) in maxilla and (42.73%)in mandible. The present study concluded that panoramic imaging is a valuable radiographic modality in detection of third molars eruption variability.

Abstract

Copper tin sulfide (Cu2SnS3) thin films have been grown on glass substrate with different thicknesses (500,750 and 1000) nm by flash thermal evaporation method after prepare its alloy from their elements with high purity.The as-deposited films were annealed at 473 K for 1h. Compositional analysis was done using Energy dispersive spectroscopy (EDS). The microstructure of CTS powder examined by SEM and found that the large crystal grains are shown clearly in images. XRD investigation revealed that the alloy was polycrystalline nature and has cubic structure with preferred orientation along (111) plane, while as deposited films of different thickness have amorphous structure and converted to polycrystalline with annealing temperature for high thickness. AFM measurements showed that the grain size of the films was increasing by annealing. The ultraviolet- visible absorption spectrummeasurement indicated that the films have a direct energy band gap. Eg decrease with thickness and increase with annealing.

Abstract

Recently, the dental X-Ray images have been used in different applications, particularly in the forensic field. The researchers focuses on the separation of the underlying teeth individually to obtain their features. These features can be utilized as a key solution for the identifications. In this paper, an edge detection of the involved teeth is proposed using a three stages MATLAB algorithm based on different methods such as, CLAHE, Canny, Otsu's, and 8-Connectivity. In addition, the proposed algorithm extracts the features of the investigated teeth as an exported file. These features are Standard Deviation (STD), Euler number and Area which are extracted from the bite-wing images. The stages of the proposed algorithm are image segmentation, classification and features extraction. It is important to note that the missing teeth has been considered in case of appearance. The missing teeth are assumed to be a separated objects. This is to overtake the problem of missing teeth after registering the original ones in the stored database used for identifications. The obtained results show the clear outperformance of the proposed algorithm in terms of edge detection and features’ extraction. The missing teeth in an image are tested and the achieved results presents the detection and features of such teeth dramatically. The proposed system is implemented and tested in the MATLAB software environment using a personal computer of a Core(TM) i7 processor and 6 GB RAM over a 64-Windows 10 operating system.

Abstract

Alloys of InxSe1-xwere prepared by quenching technique with differentIn content (x=10,20,30,and 40).Thin films of these alloys were prepared using thermal evaporation technique under vacuum of 10-5 mbar on glass, at room temperature R.T with different thicknesses (t=300, 500 and 700 nm). The X–ray diffraction measurement for bulk InxSe1-x showed that all alloys have polycrystalline structures and the peaks for x=10 identical with Se, while for x=20,30 and 40 were identical with the Se and InSe standard peaks.The diffraction patterns of InxSe1-xthin film show that with low In content (x=10, and 20) samples have semi crystalline structure, The increase of indium content to x=30 decreases degree of crystallinity and further increase of indium content to x=40 leads to convert structure to amorphous. Increase of thickness from 300 to 700nm increases degree of crystallinity for all indium content. Transmittance measurements were used to calculate refractive index n and the extinction coefficient k using Swanepole’s method. The optical constants such as refractive index (n), extinction coefficient (k) and dielectric constant (εr, εi) increases for low indium content samples and decreases for high indium content samples, while increase of thickness increases optical constants for all x values.The oscillator energyE0, dispersion energy Ed, and other parameters have been determined by Wemple - DiDomenico single oscillator approach.
