ammonium ions wastewater pollution has become one of the most serious environmental problems today. the treatment of ammonium ions is a special concern due to their recalcitrance and persistence in the environment. in recent years, various methods for ammonium ion removal from wastewater have been extensively studied. this paper reviews the current methods that have been used to treat ammonium ...

Diclofenac is a drug with an analgesic effect that accumulates and results in adverse consequences if it enters the human body more than needed. Low concentrations of diclofenac have been detected in different water sources through leachates of landfills and agricultural areas, human and animal excreta expired drug discharge and hospital effluents. To eliminate diclofenac from the aquatic e...

Multiple techniques exist to remove uroliths from each section of the urinary tract. Minimally invasive methods for removing lower urinary tract stones include voiding urohydropropulsion, retrograde urohydropropulsion followed by dissolution or removal, catheter retrieval, cystoscopic removal, and cystoscopy-assisted laser lithotripsy and surgery. Laparoscopic cystotomy is less invasive than su...

What some may like: These products provide painless hair removal that's pretty quick and can be done at home for a relatively inexpensive price. What some may not like: Depilatory products can have a strong smell or odor. Darkerhaired users may see a bit of a ?shadow? left on the skin after use due to subsurface hair.

Image dehazing is one of the most important research area in image processing and pattern analysis. Haze is naturally an atmospheric effect. And it is the combination of air light and attenuation process. Air light increases the whiteness of the image and attenuation effect reduces the contrast. Haze removal algorithms are important in many vision applications. This paper reviewed various haze ...
