Low energy high current N_2 ion beam was used to modify the morphology and chemical composition of cemented carbide WC-Co(Co:10 wt%, TiC + TaC:15 wt%, WC:bal) hard material surface for the fabrication of the TiN thin film by sol-gel method. The effects of ion beam treatment on preparation of the TiN thin film by sol-gel mothod were investigated by XPS, SEM, AFM and GXRD. According to the N_2 ion beam bombardment, the surface roughness was increased and TiC binders in WC were dissolved. The dissolved Ti was recombind with nitrogen ion to form the TiN nucleuses which were acted as seeds for the forming of the TiN thin film on the cemented WC-Co surface. Besides, the sputter deposited Ti interlayer prevented the diffusion of TiO_2 sol into the porous WC-Co during the formation of TiN thin film.

Uterus didelphys with unilateral obstructed hemivagina and ipsilateral renal agenesis usually presents after menarch with progressive abdominal pain during menses secondary to hematocolpos, and indeed a very rare congenital anomaly due to Mullerian duct malformation. An accurate and prompt diagnosis is of importance to permit treatment and to assure the future fertility of the patient. Pelvic ultrasound, physical examination and pelvic MRI established a diagnosis of hematometracolpos secondary to uterus didelphys with unilateral imperforate hemivagina. An incision in the vaginal septum allowed drainage of the hematocolpos, providing relief of the patients symptoms. We report two case of uterus didelphys with obstructed hemivagina with brief review of the literature.

A 15-year-old castrated mixed breed dog presented due to a 5-month history of cough and difficulty in ambulation. Necropsy showed multiple periosteal and intramedullary infiltrative masses in the appendicular skeleton. In addition, single and multiple neoplastic nodules were observed in several organs, including the lungs, liver, kidney, and heart. Microscopically, several skeletal neoplastic masses and nodules in the parenchymal organs revealed similar changes. The neoplastic cells were spindle- to polygonal-shaped with prominent osteoid production and occasional cartilaginous and bone formation. Based on the gross findings and histopathology results, the case was diagnosed as multicentric osteosarcoma with systemic metastases.
