introduction: the aim of this in vitro study was to compare the effect of hand and rotary instruments on fracture strength of tooth roots. materials & methods: thirty two teeth were randomly divided into two experimental groups of 15 each and one negative control group with two samples. in group 1, step-back technique with conventional stainless steel k-files was used, and in group 2, instrumen...

Potatoes are among the leading staple crops due to nutritional value and high demand. The undersized damaged potatoes considered low grade mainly dumped as a waste or used in animal feed. study aimed extract starch from potatoes, its modification improve properties formulation of gluten free cookies using modified (MS). was extracted low-grade three varieties known Asterix, Kruda Mosaic, water ...

mechanical properties of grain are influenced by various factors including soil nutrients and grain moisture content at harvest time. in order to reduce mechanical losses, the design of different processing operations should be performed based on the knowledge of factors influencing the mechanical properties. the effects of urea fertilization methods and grain moisture content at harvest time o...

converting the organic wastes and losses into compost is an appropriate technique to stabilize organic materials. one of the limitative factors in transporting and storing the composts is their low specific mass which usually leads to increase costs in their processing. to overcome this limitation, several methods such as pelleting have been proposed especially for efficient processing of powde...

In this paper, a new technique is proposed for automatic segmentation of multiple sclerosis (MS) lesions from brain magnetic resonance imaging (MRI). The technique uses textural features to describe the blocks of each MRI slice along with position and neighborhood features. A trained support vector machine (SVM) is used to discriminate between the blocks in regions of MS lesions and the blocks ...
