introduction: low back pain (lbp) is the most common musculoskeletal disease. monochromatic infrared photo energy (mipe) and low level laser therapy (lllt) are light modalities used to reduce pain and increase blood flow. the aim of this study was to compare the effects of the mipe and lllt in reducing functional disability and pain as well as improving lumbar range of motion (rom) in patients ...

this paper proposes a low voltage (±0.55v supply voltage) low power (44.65µw) high common mode rejection ratio (cmrr) differential amplifier (d.a.) with rail to rail input common mode range (icmr), constant transconductance (gm) and enhanced frequency performance. its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

educational psychology has approved that children will become accountable if we let them to make their own decisions, and they will be grown up self-confidence if we trust them. according to the same matters, the article no.12 of children’s rights international convention suggests providing opportunities for children to be able to make decisions whether by themselves or their representatives. t...
