Benign Paroxysmal Positional Vertigo
Abstract: Benign paroxysmal positional vertigo (BPPV) is the most common form of positional vertigo that occurs due to disorder of the inner ear’s vestibular system. A total of 17–42% of patients are diagnosed with BPPV every year. The prevalence of BPPV increases with age and is seven times higher in those older than 60 years. BPPV is most commonly idiopathic but also related to advanced age, ear disorders and head injury. …

Potato Starch-Based Composites for Industrial Application
Abstract: Plastic has become an essential element in our daily life. Plastics derived from polyolefins such as polyethylene are currently used in plastic film for food wrapping, garbage bags, mulching, compost bags, and many more. These plastics are typically inactive and resistant to microbial attack and hence they remain in nature for a long time without any deformation and has a harmful effect on atmosphere. Biodegradable plastics can help solve this …
