excitable cells (Catterall, Goldin, & Waxman, 2015). Voltage-gated sodium channels open or close to in response to the movement of sodium concentration between inside and outside of the cells. Voltage-gated sodium channels consist of two gates which function separately. An activation gate that opens when being stimulated while an inactivation gate closes and prevents the entry of sodium ions (Martini, Nath, & Bartholomew, 2015, p. 401). Voltage gated sodium channels anticipate in depolarization,…

Analyse the values of voltages in generation, transmission and distribution? Task 4 (D1) Electricity has greatly evolved from what it once was, to be fit for our modern day consumption and usage. Electrical engineering was first pioneered in the early 19th century, and great progress had been made by the time the 19th century came to a close. Most of the advancements were made by the likes of Thomas Edison, Nikola Tesla and George Westinghouse; who all aided in making electricity what it is…

I. INTRODUCTION The performance of present computing systems has increased at the cost of considerably enlarged power consumption. The increased power consumption either reduces the operation time for battery powered systems, such as hand-held mobile systems, or generates extreme amount of heat and requires expensive sophisticated packaging and cooling technologies, especially for complex systems that consist of several processing units. The generated heat, if not efficiently removed, can also…

explains the relationship between electric current, voltage, and resistance. The ohm’s law was named after the German physicist Georg Ohm who discovered this rule or law. Ohm’s law statement Ohm’s law states that the electric current flowing through a conductor is directly proportional to the voltage and inversely proportional to the resistance. In other words, the electric current flowing through the conductor increases with increase in applied voltage (If resistance is not changed) and the…

Minho sprinted across the street, taking a sharp turn into the darkened alley. The place stank of rot and decay. He pulled the hankerchief further up his face, attempting to block out the smell. It did little. "Let's get this shucking thing over with," he muttered darkly, and with a mirthless smile to accompany his hardened eyes. He walked out the other end of the alley and searched for a house labeled 42. Most of the houses were ransacked and burnt, the windows were boarded. Minho eventually…

a. Describe 5 major advantages associated with High Voltage Direct Current (HVDC) distribution systems when considered alongside alternative solutions. [5 marks] i) HVDC have lower losses when compared to the equivalent AC cable distribution. The DC power transmission lines run at losses of approximately 0.3-0.4% per 100km. Converter stations also need to be considered which have losses of around 0.6%. Overall HVDC transmission losses are nearly always lower than AC transmission. ii) HVDC…

Figure 5.8 is a pulse height spectrum of the net counts of the beta- emitting radionuclide, 137Cs as a function of pulse height voltage. Within Figure 5.8, the majority of the counts reside in the low voltage region, below 25 mV. It is possible to discriminate the between the different particle types by virtue of the pulse height distribution and establishing detection window threshold within the detection unit. As discussed earlier, it is possible to establish a lower threshold limit that…

forms a conduction path for the filter inductor current. The voltage across the filter inductor is the reverse of the output voltage. By using filter inductor volt-second balance rule, (VDC-Vo)dTs = Vo(1-d)Ts (1.1) Vo = dVDC (1.2) As observed from equation (1.2), the regulated output voltage (Vo) is lower than the input voltage(VDC). Interleaved Buck Converter has…
