Carbon sequestration potential of Eucalyptus camaldulensis Dehnh and Acacia salicina Lindl planted in 1980 was studied at the age of 30 years in the elevation plain areas of Iran. Two station of this plantation in province were selected the sample plots and the diameter at breast height of all trees was measured. At least, there trees from each diameter class were randomly selected and cut and ...

The condition of an abnormal pulmonary artery supplying a sequestrated segment is not well known although more than 30 cases have been described. The fact that these cases have come from a few centres (Pryce, 1946; Pryce, Sellors and Blair, 1947; Butler, 1947; Douglass, 1948; Bruwer, Claggett and McDonald, 1950; McDowell, Robb, Hinds and Nicks, 1951; Kergin, 1952; McDowell, Robb and Indyk, 1955...

In this paper, we present a practical identification approach of video fragment for digital video files. Before analyzing the video content, we must decode it based on its encoding format first. In order to effectively identify the format of a fragment, a format classification is performed before the format identification. The methods of format classification and identification are discriminati...

We made a prospective study of 43 consecutive patients treated for intraforaminal (34) or extraforaminal (9) herniations of a lumbar disc by excision through an interlaminar approach, using an operating microscope. The intraforaminal herniations were contained or extruded in 52% and sequestrated in 47%; for extraforaminal herniation the proportions were 66% and 33%, respectively. There was addi...

It has already been shown, using a local model, that accretion discs with cooling times t cool ≤ 3Ω −1 fragment into gravitationally bound objects, while those with cooling times t cool > 3Ω −1 evolve into a quasi-steady state. We present results of three-dimensional simulations that test if the local result still holds globally. We find that the fragmentation boundary is close to that determin...

When complementary fragments of the imaginal wing disc of Drosophila are cultured for several days prior to inducing metamorphosis, usually one fragment will regenerate while the second duplicates. It has been proposed that wound healing plays an important part in disc regulation by initiating cell proliferation and determining the mode of regulation (regeneration/duplication). To test the latt...

Disc fragments are well known to migrate to superior, inferior, or lateral sites in the anterior epidural space, posterior epidural migrated lumbar disc fragments is an extremely rare disorder. Posterior epidural migrated lumbar disc fragments are often confused with other posterior epidural space-occupying lesions (cysts, abscesses, tumors, and hematomas). We reported the case of a 52- year-ol...

We have performed magnetohydrodynamic (MHD) simulations of the collapse and fragmentation of molecular cloud cores using a new algorithm for MHD within the smoothed particle hydrodynamics (SPH) method, that enforces the zero magnetic divergence constraint. We find that the support provided by magnetic fields over thermal pressure alone has several important effects on fragmentation and the form...
