Frequency

action potential begins when a depolarization increases the membrane voltage so that it crosses a threshold value. 3. If a strong stimuli (suprathreshold) is applied, how is it reflected when we observed an action potential? It can increase the frequency of action…

fulfill surveys related to their online activities, such as the frequency of browsing foreign websites and rank the importance of various domestic and foreign media news sources. However, I think Chen and Yang needs to make it more clear on the relationship between the frequency of browsing foreign websites and the rank of news sources. For example, they can use existing browsing data to determine how rank of news sources relates to the frequency of browsing foreign websites and then use the…

Gustavo Oliveira Coutinho, 4º ano Class: 4BTEL Innovate Tesla: the resurgence of Nikola Tesla from oblivion to spotlight Introduction Nikola Tesla is one of the most controversial figures on science. While many judged him simply as a mad scientist, few were able to see how he was ahead of his own time, providing the theoretical and practical foundation to several modern equipments. We, as a society, not only owe Tesla for the AC (alternating current) electric system of supply, but…

generated by a heater, which was placed on one end of a dielectric resonator. The AC potential difference between an electrode that was placed on the opposite end of the resonator and the ground was recorded. The resonance frequency of the electric response corresponded to the frequency of the second sound…

The introduction of this lab report discussed and elaborated how muscle contraction is an intricate and precise step-by-step process in the body. The concepts outlined at the introduction intertwine with the experiments performed in this laboratory. The experiments aimed to showcase the physiological cause and effect of skeletal muscle response towards various settings. For instance, the first experiment demonstrated spatial summation through the form of muscle recruitment. The cause of this…

had been going on today. “RRRRRRR” came a noise out of nowhere. “Ahh” I said as a woke up startled. “Oww” said as my ears were hurting. Something's wrong, this is not known to happen. What is Taos Hum? The Taos hum is about a mysterious low frequency (30-80 Hz) sound that is usually heard at night in the town of Taos. It sounds like a truck starting up but only so many people have heard it. Lots of hearers initially reported the hum with an “abrupt beginning, as if some device were…

To save the lives of people, the firefighter is there to risk their own life just to save others. They are considered to be the real heroes of the world. Their main duty is to save the life of a civilian and to protect the civilian property. When a firefighter enters the burning building, the first main purpose of him is to save the life of the civilians and then to ensure that less damage is made to the property (Kunadharaju, Smith & DeJoy, 2011). When these two goals are accomplished, the…

Respiratory Care Journal (Rittayami, Tscheikuna, Praphruetkit, & Kijpinyochai, 2015). The study had two goals: (1) to evaluate the level of dyspnea after use of HFNC (2) to evaluate patient’s comfort, change in breathing rate, adverse effects, and frequency of hospitalization (Rittayami et al., 2015). Forty randomized subjects participated in…

Humanity has tainted Earth with its constant production of carbon emissions. Many people do not acknowledge the effects of carbon emissions on Earth, even though they are clear. In recent years, the frequency of forest fires, hurricanes, and other natural disasters has increased. This increased frequency of natural disasters will inflict mass damage to coastal cities. Guillermo Del Toro’s Pacific Rim reflects this observation of climate change by comparing the film’s antagonists to natural…

Journal November 15 –– Summarize the last 10 years (2005 – 2014) regarding hate crime victims, victimization, bias motivation and crime type. Does this information surprise you? Why, or why not? After accessing and viewing the report on hate crime in California I discovered a graph conducted by the U.S. Department of Justice illustrating the statistics of disclosed hate crime incidents from 2005 to 2014. The chart lists some of the listed categories of hate crimes including: Race, ethnicity,…
