Introduction: The purpose of this lab was to determine the effects of increasing load on muscle recruitment, compare muscle recruitment between concentric and eccentric muscle movement and the effect of muscle fatigue on muscle recruitment during submaximal exercise. Hypothesis: The higher the weight increased the greater the motor unit recruitment would be. The motor unit recruitment would be greatest during the concentric phase rather than the eccentric phase. The more fatigued the muscle becomes the motor unit recruitment would be significantly less. Methods: Two surface electrodes were placed parallel on the belly of the bicep and one electrode on the bony process of the elbow on a Subject.
When making connections it is so much easier to splice the copper cable than it would be for the fiber. Copper cables are also very flexible; you can have your wire go wherever without cracking or breaking. As for the disadvantages, all the advantages of the fiber are the downfall of the copper cabling. People want faster, better, farther. So, over time, we will lose the copper cables and move onto the
It is known that chlorine is more electronegative than bromine, and thus chlorine is more reactive, and less discriminatory as to what it will react with, thus making bromine more “selective”. Another pertinent piece of information to look at would be stability. The stability of a free radical increases as the number of carbon substituents increases. Therefore, primary is the least stable and tertiary is the most stable. Also, the more stable the free radical that is left behind, the weaker its C-H bond strength will be.
A slower process than MIG, it produces a more precise weld and can be used at lower amperages for thinner metal and can be used on exotic metals. TIG does require quite a bit more time than MIG to learn. It is similar in technique to gas welding. TIG can be used with pure helium or argon as an inert shielding gas to protect the weld pool from the atmosphere. (Nitrogen, hydrogen, oxygen, carbon dioxide, and other elements cause weld defects if introduced to the weld pool.)
The differences over cost driver between LG and TORK are mainly come from the followings, please see below: Design: LG uses the plastic parts which the weight is lesser than Tork steel’s part and also the cost are cheaper. Moreover, the assembled times of LG are faster than Tork along with the wages rate of LG are lower. In conclusion, LG are cheaper and faster than Tork Geography: The freight costs of LG are significantly higher due to requiring ocean freight and shipping to distribution centers, whereas Tork relies on trucks and trains. However, LG enjoys a large wage advantage in Korea. Facility: LG has higher manufacturing volume based on they has an advantage from scale of economies by purchasing lots of material and got the discount on the prices.

Structures require foundations in the ground and solid foundations are dependent on a soil’s shearing resistance. Moreover, the shear strength is needed for engineering situations such as calculating the pressure exerted by a soil on a retaining wall, sheet piling, determining the stability of slopes or cuts and determining the bearing capacity for foundations. In this Laboratory, a direct shear device will be used to determine the shear strength of a cohesionless soil. In this case, dry river sand was used.
An activity can have more than one cost driver attached to it. For example, a production activity may have the following associated cost-drivers: a machine, machine operator(s), floor space occupied, power consumed, and the quantity of waste and/or rejected output. (BusinessDictionary.com, 2013)" I think the company would do better with Activity Based Costing (ABC) because this allocation method is more accurate because it takes all cost related factors into consideration. The first way the company was allocating department costs was and even three way split, which was undercutting Fabricating, which needs more funds, and this method was overcompensating Laminating and Assembling, which require less. With the ABC Method, the costs are factored by the different cost drivers, such as machinery, staff, number of parts needed, amount of products made, as well as direct material costs and direct labor hours.
In which round will demand for performance products exceed the demand for size products? In round three the demand for performance products will exceed the demand for size products. 4. Explain how increasing first shift capacity can reduce per unit labor costs. Increasing first shift capacity can reduce per unit labor costs because you can produce more products in less time which reduces the labor costs.
Introduction The element Chromium is very important in the industrial world. It is used in nonferrous alloys such as stainless steel, in order to increase its hardness and prevent corrosion and oxidation. Chromium is only found in one ore, the mineral Chromite. Chromite’s composition is iron magnesium oxide [(Fe, Mg) Cr2O4]. Occasionally, magnesium will substitute for iron, and aluminum and ferric ions will substitute for chromium.
Low purchasing power will directly affect the aggregate production, with fewer resources are used, unemployment rate rise, there is less pressure on price, and therefore reducing the inflation rate as the supply is greater than demand. An increase in interest rate will have multiple effects. Firstly it stops firms from expanding, when the purchasing power has reduced, firms sell less and make less profit. Firms will cut the production and size of their workforces to reduce their costs; unemployment rate rise and people are less likely to spend. Secondly, the saving ratio will increase; less money is in the circulation.
