Introduction: Successful radiotherapy requires the precise application of a radiation dose to cancerous tissue, which can be achieved by the design of proper treatment methods by radiotherapy physicists. Tasks performed by radiotherapy physicists include verifying the accuracy of dose calculations, correct treatment planning and the proper functioning of accelerators. They are...

Brain imaging data acquired with MRI, PET and other modalities are usually represented as 3D image volumes, and are often analyzed and visualized as 2D slices. However, viewing brain imaging data as individual slices makes it difficult to relate the observations to the sulci and gyri of the cortical surface. We have developed surface-based visualization techniques that integrate the data from m...

This study was conducted to evaluate the effect of titanium dioxide and titanium oxide foliar application during two growing stage on growth and forage production of maize during 2012 growing season in the research farm of Islamic Azad University of Varamin-Pishva Branch. The experimental design was randomized complete blocks arranged in factorial with four replications. The factors were includ...

bioassays were conducted to assess the contact toxicity of two plant essential oils against adults of sitophilus granarius (l.) and tribolium confusum jacquelin du val. essential oils were extracted from seeds of carum copticum l. and cuminum cyminum l. contact toxicity was assessed by topical application and adult mortality was counted 1, 2, 6 and 24 h after exposure. bioassays were carried ou...

this is a comprehensive review of the recent progresses made in the field of zeolite membranes. it describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. special attention is called to polymer mixed matrix membranes (mmms) and membranes based on metal organic frame works (mofs)....

objectives: this study aimed to evaluate the effect of chlorhexidine (chx) application protocol on durability of marginal seal of class v composite restorations. materials and methods: class v cavities (4×2×1.5mm) were prepared in the buccal surfaces of 160 human third molars. the teeth were randomly divided into five groups (n=32) of (g1) chx+rinse+etching, (g2) chx+etching, (g3) etching+chx+r...
