Common Aspects of Acid Prehydrolysis and Steam Explosion for Pretreating Wood Hans E. Grethlein Michigan Biotechnology Institute‚ PO Box 27609‚ Lansing‚ Michigan 48909‚ USA & Alvin O. Converse Thayer School of Engineering‚ Dartmouth College‚ Hanover‚ New Hampshire 03755‚ USA Abstract The initial rate of hydrolysis using cellulase from Trichoderma reesei for various wood samples is directly proportional to the surface area available to the enzyme. Both dilute acid hydrolysis in a continuous

hear and are caused by vibrations that travel through mediums. Depending on the medium and temperature‚ the time it takes for sound waves to travel vary. The hypothesis states that if the temperature in the air increases‚ then the speed of sound will also increase because faster-moving particles transfer energy quickly. The data collected supports the hypothesis. Therefore‚ increased air temperature affects the speed of sound because the molecules move faster‚ which causes the energy to be transferred

goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? The goal for this lab is to be able to get the boiling water’s temperature to increase by adding table salt. The problem it is trying to explain is‚ how does table salt affect the boiling temperature of water? does it increase or decrease? or does it stay the same? Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen

4 5. According to the IS-LM model‚ what happens to the interest rate‚ income‚ consumption and invest under the following circumstances. a. The central bank increases money supply. An increase in the money supple shifts the LM curve downward. The equilibrium moves from point A to point B. Income rises from Y1 to Y2 and the interest rate falls from r1 to r2. Therefore this increase in money supply causes a decrease in interest rate‚ an increase in income‚ an increase in consumption and an increase

Part I – Relation between BI rate and banks interest rate A. BI rate We take the BI rate‚ as the variable being estimated‚ from the period of 2006 until 2012. We then take the average rate in each year‚ rather than taking the rate in each month. As a note to the year 2012‚ we take the average rate that ranges only from January until August. Figure 1.

effect of substrate concentration Hydrogen Peroxide H O (in %) on the rate of reaction of the enzyme catalase (in 1/mean time). Prediction: As the substrate concentration (hydrogen peroxide) in % increases the rate of reaction in 1/mean rate increases until the solution becomes saturated with the substrate hydrogen peroxide. When this saturation point is reached‚ then adding extra substrate will make no difference. The rate steadily increases when more substrate is added because more of the active

How exercise affects certain aspects of the body During exercise our body needs more oxygen and blood to keep the muscles activated. To grant this the heart pumps higher frequency of blood increasing the heart rate. Heart pumps blood through arteries faster resulting in a high blood pressure. Exercise increases the stroke volume (the amount of blood pumped in one beat)‚ so an increase in stroke volume means that the heart can pump enough blood to the body with fewer beats per minute. Even after the

The genetic code A DNA (deoxyribonucleic acid) is composed of 4 different bases; adenine (A)‚ guanine (G)‚ cytosine (C) and thymine (T). Applying these 4 bases it may contain thousands of sequences within a single strand. Each of these bases makes a specific pairing with a corresponding base whereby the double helix structure is synthesised. This interaction is called base-paring and the complementary base pairs are; T pairs only with A and C only with G. Through this simple coding language‚ the

Difference between rate and sequence Rate/Speed involves a time frame linked to age. Sequence/Order involves patterns and an order of development linked to body‚ mobility and intellectual growth - sequence can include an order that’s both positive and negative - deterioration. Rate - what happens at 1 year old‚ 24 months old‚ 7 years old .. Sequence - how things happen in an expected order‚ sequence ie: breastfed‚ weaned‚ full meals. lie‚ sit‚ crawl - maybe‚ stand‚ walk‚ run.. Sequence
