Dementia in Stroke Survivors in the Stroke Data Bank Cohort

We determined the prevalence of dementia in 927 patients with acute ischemic stroke aged
years in the Stroke Data Bank cohort based on the examining neurologist's best judgment
Diagnostic agreement among examiners was 68% ( K = 0 3 4 ) . Of 726 testable patients, 116 (16%)
were demented. Prevalence of dementia was related to age but not to sex, race, handedness,
educational level, or employment status before the stroke. Previous stroke and previous
myocar ....etc

ABSTRACT

Are two stroke motorbikes poised for a comeback? With new development, they can compete with four stroke in emission cleanliness, full economy & rideability while retaining power, size & weight advantages.
Now days this is the age of four-stroke engme. Because of its various advantageous like mileage, power and one of the greatest advantage is that it's emission.
And therefore it is certify that it is cleanliness and made very low pollution. Because of this the two stroke engine is l ....etc

The six-stroke engine

The est -storke dvigatel a type of internal combustion engine based on the four-stroke engine, with more difficulty, But intended to make it more efficient and reduce emissions. Two types with six stroke engine was developed from the 1890 's:

In the first approach, which is called a piston engine design captures the heat loss of the four-stroke Otto cycle or diesel cycle and uses it to power additional power and exhaust stroke of the piston in the cylinder of a year. Designs use either steam or air as a working body f ....etc

There is a concept 8-stroke engine that has been proposed, but no implementation practice of it (or a 6-stroke engine for that matter) exists in a form that is suitable for road vehicles.

The idea of adding more shots than the original 4-stroke engine is as old as the 19th century. The idea is to use the thermal mass of the engine to recover a portion of the thermal energy of waste otherwise. In a 6-stroke engine, in addition to the original 4-time, there is also a race of injection water, followed by a run of expansion of steam power (mainl ....etc

A four-stroke engine (also known as four cycle) is an internal combustion (IC) engine in which the piston completes four separate strokes while turning a crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed:

Intake: This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum p ....etc
