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

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

Best Answer: there was such a thing as a 8 stroke, actually called a hit and miss, where it was your usual 4 stroke but it only fired every other revolution, there were several designs, but basically the magic was done in the valve train and ignition system, and the help of a rather large and heavy flywheel, the more complex ones would open the exhaust valve instead of the intake valve every other revolution, thus cutting the fuel consumption in half in theory, mostly used in industrial applications where high torque and low RPM were desirable ....etc

How to Assemble and Build A PC

Installing the
motherboard:

Make sure you have all the
components in place and a nice,
clean and big enough place to work
with.
Put your antic-static wrist strap on to
prevent your components from
getting affected. Make sure your
hands are clean before starting. First
we will be installing the motherboard
which is a piece of cake to install.
Open the side doors of the cabinet
Lay the cabinet on its side
Put the motherboard in place
Drive in all the required s ....etc

abstract
An opposed-piston hydraulic free piston engine operating with homogenous charge compression ignition (HCCI) combustion, has been proposed by State Key Laboratory of Engines as a means of significantly improving the IC engine s cycle thermal efficiency and lowering exhaust emissions. Single and multi-zone Chemkin model with detailed chemical kinetics, and unique piston dynamics extracted from one dimensional gas dynamic model, have been used to analyze the combustion characteristics and engine performance. Intake heating, vari ....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

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
