The performance of a polarizing beam splitter based on the one-dimensional photonic crystals (1D-PCs), is theoretically investigated. The polarizing beam splitter consists of a symmetric stack of the low-index quarter-wave plates and the high-index half-wave plates with a central defect layer of air. The linear transmission properties of the polarizing beam splitter are numerically simulat...

keratocystic odontogenic tumor (kcot) is a benign intraosseous neoplasm of the jaw occurring most commonly in mandibular ramus molar area with male predilection. peripheral kcots are very uncommon. here we report a case of keratocyst in buccal mucosa in a 55 years old female patient, the diagnosis of which was based on subjective histological evaluation and further confirmed by immunohistochemi...

Chitosan (CS)-polylacticacid (PLA)-polyethylene glycol (PEG)-gelatin (G) nanoparticles, a novel drug vehicle for the controlled release of an antitubercluosis drug, rifampicin (RIF) was developed and its chemical and biochemical activities were studied by various standard methods. The designed carriers CS, PEG and G nanoparticles were prepared by emulsion solvent evaporation technique, and then...

Attention has recently been drawn to the similarity between the histological picture of silicious granuloma and tuberculosis of proliferative type in the Fallopian tube of man (Roberts, 1947). In the differential diagnosis emphasis has been placed on the value of the polarizing microscope. The purpose of the present paper is to draw attention to the presence of doubly refractile, but non-silici...

This report includes the clinical, radiological, morbid anatomical, and histological findings in the lungs of a man who for a continuous period of 45 years had been engaged in the loading and unloading of coal in ships and trains. He presented as a case of congestive cardiac failure with signs of severe pulmonary hypertension. The chief feature in the lungs was the presence of silicoticlike nod...

Gout is a form of crystal arthropathy where monosodium urate (MSU) crystals deposit and elicit inflammation in a joint. Diagnosis of gout relies on identification of MSU crystals under a compensated polarized light microscope (CPLM) in synovial fluid aspirated from the patient's joint. The detection of MSU crystals by optical microscopy is enhanced by their birefringent properties. However, CPL...

The Middle Jurassic Sargelu Formation spreads out widely in North-Eastern Iraq, particularly within the High Folds Unstable Shelf Zone. was studied two exposed sections, Hanjira and Gorin, Northeastern part of Iraq. Lower contact formation with Sehkaniyan Upper Naokelekan sections appears conformable. thickness section is 40m. Gorin 70 m. sampling done by taking samples from thin were made for ...
