In this paper we present a new method for fully automatic liver segmentation in computed tomography images. First, an initial set of seed points for the random walker algorithm is created. In this context, voxels belonging to air, fat tissue and ribcage are labeled as background. Furthermore, depending on the shape of the ribcage and voxel intensities, several seed points inside the liver are a...

tamarinda (tamarindus indica) and indian gum arabica (acacia arabica) are two ornamental trees of beautiful shape, extensive shading, and tolerant to high temperatures, making them suitable alternatives for landscape design in warm- arid regions. tamarinda and indian gum arabica are commonly propagated by seed. however, seed physical dormancy causes delay in seed germination. this study was car...

Mango (Mangifera indica L.), an edible fruit, is one of the main agricultural products in many tropical regions. Mango varieties differ in not only fruit shape but also aroma, which is an important characteristic. Although the fruit has many uses, the seeds are discarded as waste. Therefore, this study aimed to estimate the fatty acid content of seed oil of mangoes from different cultivation ar...

Pine seed mass is isometrically related to samara shape among smaller seeded pines (< 165 mg), but not when larger seeds are included (putative bird-dispersed pines excluded). Among the largest pine seeds samara length declines with increases in seed mass. Consequently, disc-loading increases and dispersal capacity declines at an accelerating rate with increases in seed mass. The acceleration i...

We combined data on gut-passage times, feeding, and movement to explore the patterns of seed dispersal by Eulemur rubriventer, Eulemur rufrifrons, and Varecia variegata editorum lemurs in Ranomafana National Park, Madagascar. These lemur species deposited less than half of their consumed seeds >100 m away from conspecific trees (40-50%). Long-distance dispersal (>500 m) was rare and average dis...

The sequential separation of male and female function in flowers of dichogamous species allows for the evolution of differing morphologies that maximize fitness through seed siring and seed set. We examined staminate- and pistillate-phase flowers of protandrous Saponaria officinalis for dimorphism in floral traits and their effects on pollinator attraction and seed set. Pistillate-phase flowers...

Coating of particulate solids by a thin film layer is of interest in many industrial applications such as seed and tablet coating. In seed processing, seeds are commonly coated with a protective coating layer consisting of fertilisers and crop protection products. Rotary drum batch coaters are typically used for this purpose. The coater consists of a cylindrical vessel with a rotating spray dis...
