Mathematical Formula in Material Cost Accounting and Control Essay

Mathematical Formula in Material Cost Accounting and Control - Essay Example Also, overstocking requires more storage space which, in turn, means an increase in insurance expenses, storage costs and deterioration in quality and depreciation in quantity. On the other hand, if materials are understocked, frequent orders have to be placed in small quantities and there is a chance of "stock outs" also. Hence, the tack of the manager is to find the most economic order which s very essential for cost management and control. The cost of carrying the inventory and the ordering cost is inversely proportional to each other. The costs of placing the order decreases as the size of the order increases, because with the bigger size of the order, the number of the orders will be lower. However, simultaneously the costs of carrying the inventory will go up because the purchases have been made in large quantities. It may be possible to have appointed which provides the lowest total cost and the point, which is the ideal size of the order is known as the Economic Order Quantity(EOQ). The EOQ is one where the cost of carrying inventory is equal or almost equal to the cost of not carrying inventory (cost of placing the order), i.e., at EOQ level, the total of inventory carrying cost and the ordering cost is minimum which can be determined mathematically s follows: The EOQ is 600 units, i.e., 10 orders per year are needed.

Physiological Psychology - Assignment Example It answers to stress by augmenting the heart rate and flow of blood to the muscles. It encompasses quick response and hence concerned with â€Å"fight or flight†. Parasympathetic nervous system, encompass cranial nerves (nerves of brain) and also the lower spinal nerves i.e. nerves of sacral region. Action of this system counteracts the sympathetic actions by increasing digestive secretions and decreasing the heartbeat. It is concerned with â€Å"rest and digest†. It is evident that ANS encompass afferent pathways that includes information from the viscera and brain and hence maintains the homeostasis. It has both sensory and motor neurons to carry the information to and from the brain and spinal cord. An action potential along the axon is dependent on influx of sodium ions and efflux of potassium ions. The phases of action potential are: rising phase- In the resting state the inside of the neuronal cell is polarized (-70mv) as compared to its outside charge. Therefore, it is polarized. Excitatory neurotransmitters like aspartate and glutamate released from their pre-synaptic neurons attach to post-synaptic dendrites, sodium channels open up leading to influx of positively charged sodium ion gradually more and more sodium ion channel open up resulting in positive charge inside the cell (+40mv inside cell) and the cell is said to be depolarized. Falling phase- sodium ion channels are closed and potassium ion channels open up as a result potassium being an intracellular ion moves out through these channels and by this process there is a net loss of positive charge as potassium is positively charged ion. Myelinated axons prevent the back diffusion of ions to outer space and ensure a fast and rapid conduction of action potentials. Myelinated neurons contains nodes of Ranvier, through this action potential jumps, this is called salutatory conduction. The
