Cerebral blood arteries dilate and constrict due a process called cerebral autoregulation. 3. This process is affected by stroke 4. One possible ischemic stroke occurs due to blockage of an intracranial vessel due to an embolus from a distant area (i.e. cardiogenic embolus)‚ 5. Another possible ischemic stroke occurs due to in situ thrombosis of an intracranial vessel

An investigation into the effects of sugar concentration on yeast activity Introduction: Yeasts are eukaryotic micro organisms belonging to the kingdom fungi. Yeasts live on sugars and produce ethanol and carbon dioxide as by-products. [James Mallory‚ 1984]When Yeasts are given water and sucrose they convert the sucrose into glucose then convert the glucose into carbon dioxide and ethanol following the following reaction: C₆H₁₂O₆ ( 2(C₂H₅OH + CO₂ [Brady Burkhart‚ Terrell Grayson and Eric Kimler

The Effects of varying p-Nitrophenyl Phosphate concentrations on Alkaline Phosphatase Activity Nathan Overholt Louis Settembrino March 5‚ 2002 Abstract: The enzyme Alkaline Phosphatase was set up in solutions of varying p-nitrophenyl phosphate concentrations. A fixed time assay was used to find the Michaelis constant and Vmax. All solutions were incubated at 30 C° for 30 mins. Absorbances were measured at 405 nm‚ and the Km was found to be 0.002 M (pNPP) and the Vmax to be 0.433 A/min. Introduction:

The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase

TEXT DESCRIPTION OF THE SIX-STROKE ENGINE INTRODUCTION: The majority of the actual internal combustion engines‚ operating on different cycles have one common feature‚ combustion occurring in the cylinder after each compression‚ resulting in gas expansion that acts directly on the piston (work) and limited to 180 degrees of crankshaft angle. According to its mechanical design‚ the six-stroke engine with external and internal combustion and double flow is similar to the actual internal reciprocating
