1. The given margins of the two products as indicated in the reports submitted by the accounting department for the drums and mountain bike frames should not be used in the decision of which product to make. This is due to the following reasons: a. The product margins are lower than they should be‚ simply due to the fact of the presence of allocated common fixed costs that happen to be irrelevant in making this decision. b. Moreover‚ when the fixed costs are taken out of the equation‚ the profitability

A buffer solution can maintains a narrow range of pH even when strong acid are added. In our experiment‚ we can see water is not a buffer‚ water can undergo very big changes when small amounts of strong acid or strong bases are added. When the strong acid‚ 100µl HCl was added into the dd water‚ the pH value changed from 7.38 to 5.83 which mean the dd water has turn into acid. The same phenomenon occurs while strong base‚ 100µl NaOH was added into the dd water. The pH value changed from 7.07 to 9

BUFFER SOLUTION (ACID) An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt. Objectives: 1. Measure the pH of the unknown solution first with indicators and then with pH paper. 2. compare the buffer solution with both a strong acid and a weak acid materials: 2 30 mL beakers 2 100mL volumetric flask 1 10mL pipet 2 aspirator 1 50mL graduated cylinder 1 10mL graduated

Buffer systems * prevent major changes in pH of body fluids by removing or releasing H+ * act quickly to prevent excessive changes in H+ concentration. Body’s major extracellular buffer system is “bicarbonate-carbonic acid buffer system”. There are 20 parts of (HCO3) to one part of (H2CO3). ---- [20:1]. When the ratio is no longer maintained‚ it will result to acid-base imbalance. Carbon dioxide is a potential acid; when dissolved in water‚ it becomes carbonic acid. Lungs under the

Analysis on many of the benefits of children skipping rope By Danica Jan 10‚ 2012 The reason for loving skipping: children like the bouncing movement‚ not only well-developed and healthy‚ also the intelligence will be improved. The following is the brief analysis on the four benefits of skipping rope. First‚ the more jumping the better cardiopulmonary function. Skipping rope can speed up blood circulation‚ and improve cardio-pulmonary function and respiratory function; accelerate the gastric motility

Dating back to the slave trade the drum has been used all over the world as a means of communication and self expression. Its broad variety of users includes the early African tribes and the Native Alaskan tribes‚ both using them for ceremonial purposes. The Africans brought drums with them to the Americas and helped to develop their popularity among American musicians. In the mid 1900’s drum sets were brought about. These revolutionary collaborations of percussive pieces started off with a pair

Scheduling Basics DDMRP uses buffered “Decoupling Points” to establish independent planned and scheduled horizons. DDMRP creates resupply signals based on the “available stock” status of each buffer. This gives prioritized sequence based on actual need. On-the-floor priority is then determined by the real time buffer status of the decoupling points that the open orders are feeding. When Will we Need More Scheduling Capability? • When the use of better shop floor scheduling will compress lead times and
