Various forms of muscular dystrophy, an inherited disease that causes progressive muscle weakness, can contribute to foot drop. So can other disorders, such as polio or Charcot-Marie-Tooth disease. Brain and spinal cord disorders. Disorders that affect the spinal cord or brain â such as amyotrophic lateral sclerosis (ALS), multiple sclerosis or stroke â may cause foot drop. Risk factors. The peroneal nerve controls the muscles that lift your foot. This nerve runs near the surface of your skin on the side of your knee closest to your hand. Activities that compress this nerve can increase your risk of foot drop. Examples include: Crossing your legs.
Measurement unit conversion: ng/l. âºâº Measurement unit: ng/l. âºâº SI unit: kilogram/cubic meter. The SI derived unit for density is the kilogram/cubic meter. 1 kilogram/cubic meter is equal to 1000000000 ng/l.
A sulphur-based odourant is normally added to CNG to facilitate leak detection. Natural gas is lighter than air and thus will normally dissipate in the case of a leak, giving it a significant safety advantage over gasoline or LPG. Liquefied Natural Gas or LNG is natural gas stored as a super-cooled (cryogenic) liquid. The temperature required to condense natural gas depends on its precise composition, but it is typically between -120 and -170Â°C (-184 and â274Â°F). The advantage of LNG is that it offers an energy density comparable to petrol and diesel fuels, extending range and reducing refuelling frequency.
