conclusions an increased lumbar lordosis during the prone knee-flexion test is due to instability in a lumbar spine region. results results demonstrated that there was a statistically significant difference in lumbar lordosis in prone position and after performing the prone knee-flexion test among healthy subjects (p < 0.0001). patients and methods this quasi-experimental study with repeated me...

Drought is the most significant constraint for crop production in arid and semi-arid regions. In order to assess drought tolerance in fifteen rapeseed (Brassica napus) cultivars using yield-based drought tolerance indices, two experiments were conducted at the research station of College of Agriculture, Shiraz University, Shiraz, Iran during 2009-2010 growing season. The cultivars were...

lumbar puncture (lp) is a procedure for obtaining spinal fluid from spinal meningeal spaces this can be done as a diagnostic or therapeutic procedure which can result in to a typical positional headache named as post lumbar puncture headache .this can cause a lot of discomforts for patients and makes fear from the procedure. this study designed to evaluate the effect of resting position after l...

The coordination of a large group of robots to solve a specified task is a difficult problem. Centralized approaches can be computationally intractable, brittle, and unresponsive to change. Distributed approaches are not as prone to these problems, but they can be highly sub-optimal. This work introduces a novel economic approach for coordinating robots based on the free market system. The free...

We propose a newmethod for digital watermarking of images based on Fractal Image Coding using Ridgelet Transform and Discrete wavelet transform (DWT). The method takes Ridgelet transform of the image to get a transformed image and performs 2-level Discrete Wavelet Transform(DWT) on the transformed image to get low frequency sub-bands LL2 and LL1. LL1 is used for range blocks and LL2 is treated ...
