The intricate reaction between the human’s physiological and psychological responses has been long disputed (Rowbotham, 2001) This ever changing discussion may be explained by the neuromatrix pain theory (Melzack, 1999). However, our understanding of the physiological response to a painful experience and its effects on the body has changed over the years. In the mid-17th century the pain theory was over simplified; nerve impulses travelled to the cerebral cortex in the brain, the more damage the…

Currently, pancreatic cancer is the fourth leading cause of cancer-related deaths in the United States. Furthermore, the five year survival rate of individuals diagnosed with pancreatic cancer has been estimated at just below 5%. This can be attributed to the fact that pancreatic cancer often progresses stealthily and physical symptoms (jaundice, abdominal pain, and weight loss) do not present until the cancer is in its later stages. As a result, the best way of treating pancreatic cancer is to…

The released Glutamate binds to and activates receptors in the postsynaptic nerve terminal (the dorsal horn neuron)[1]. Specifically activation of α-amino-3-hydroxy-5-methylisoxazole-4-propionate (AMPA)-type and N-methyl-D-aspartate (NMDA)-type glutamate receptors lead to depolarization and the generation of action potentials which transmits…

mode of the electrical connection will also determine the motor operating characteristics. Self-excited and separately excited is where the winding terminals are connected across the input voltage and separate voltage source respectively. 1.5 Efficiency of a DC motor Some power loses takes place as power flows from the input to the output terminals of the motor. Therefore, the motor efficiency can be calculated as the ration of the output power to the input power. Efficiency = power output /…

Abstract: Electrochemical machining (ECM) is a technique of eradicating metal by an electrochemical procedure. It utilizes an electrolyte and electrical current to ionize and eradicate metal atoms. Electrochemical Machining is a relatively ancient machining system which basis were laid way backside in the 19th century. The process has enhanced extremely everlastingly since, thus becoming an extremely defined practice with gigantic limitless application possibilities across engineering. In this…

(Goodman & Fuller, 2015). Moreover, the effects of a stroke depend primarily on the location of the obstruction and the extent of brain tissue affected (Hossmann & Heiss, n.d.). Spasticity is a post stroke motor disorder which characterized by a velocity dependent increase in tonic stretch reflexes after a lesion in the descending corticospinal system (Thibaut et al., 2013). This is a common is a symptom affecting 30% of stroke patients which could result to functional impairments (Thibaut et…

environment Vertical Handover is executed thus a user can switch among different radio access networks that makes whole process so complex. Vertical Handover algorithms require many parameters such as interference power, QoS, network conditions, terminal capabilities, monetary cost and so on. Only RSS measurements are not enough in VHO’s case. Consequently, the VHO decision process becomes significantly complex. This paper presents a synopsis of Handover management process and focuses on…

1. Overview: Although flight history is full of unfortunate deadly incidents, planes are statistically the safest mean of transport. Saving money and time and safe trips are the main reasons why airplanes are the first choice when it comes to travelling especially for long distances. With the explosion of client demands and the mass production of aircrafts, managing the air traffic becomes harder and eventually the current managing system will fail against the enormous number of airplanes…

helps make decisions about arriving aircraft and includes real-time radar track data, flight plan data, wind speeds and directions. Information is updated every 12 seconds and computes routes and optimal schedules. The TMA is a part of the Center-Terminal Radar Approach Control (TRACON) Automation System (CTAS). This system maximizes runway utilization by providing controllers with aircraft sequence numbers and runway assignments. These systems depend on improvements and updates to radar…

My Trip to Detroit Mountain: It all started about 1 year ago, when the 8th grade went on the bus to get to Detroit Mountain. It was 6 A.M., and I was exhausted. Reason being, I had to wake up at 5 A.M. to get myself through my morning routine and still get there on time. The ride there took an hour and a half (But if felt like 3 hours). Then the real bullcrap starts to take place. After I got there I spent an hour getting past the bunny hill so I could be allowed to go on the other hills. I…
