Oscillation

can be used investigate the relationship between the time period and the length of the pendulum, with a constant value including the value of gravity. This is apparent in the following formula; 푇=2휋√퐿푔 T – Time period; time taken to complete one oscillation L – Length of string Therefore, this apparatus and equation can be used to find out the value of gravity by varying the length of the pendulum and…

literature, peace, physiology or medicine, and physics. This year the Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics to Takaaki Kajita from Japan and Arthur B. McDonald from Canada “for the discovery of neutrino oscillations, which shows that neutrinos have mass.” Their discovery was announced to be a historic discovery for particle physics. After a various amount of experiments and calculations, neutrinos were considered massless; however, after years of…

the bridge designers accepted that response as reasonable and acceptable performance in light of the tradeoff for lightness, economy and aesthetics. The Tacoma Narrows Bridge was the most slender suspension bridge built up to that time, and its oscillations which lead to the…

redshift. This map, spanning 3/4 of the lifetime of the Universe will complement the single snapshot at z ≈1100 made by WMAP and Planck. By combining the use of Redshift measurements (4.1), Weak gravitational lensing (4.2) and Baryonic Acoustic Oscillations (4.3), both Dark Energy (DE) and Dark Matter(DM) will be investigated in the following tasks: 1. Construct a three-dimensional Dark Matter map to a depth of z=2. See Figure 2. 2. Measure wΛ. In the benchmark model, the dark energy…

photosynthesize, Instead of yeast obtaining energy to grow from the sun, it processes sugars and disaccharides to make energy, with carbon dioxide as a byproduct. While sunlight does not directly aid yeast’s growth, it does affect yeast’s respiratory oscillation, which is an activity that impacts metabolism and energy production. But how do different colors of visible light affect yeast? The objective of this experiment was to learn the effect of visible light on yeast. The goal of the…

United States alone. Although many doctors believe the cause of ET is abnormal activity of the brain, the real cause of the disease is unknown. About half of all ET cases are believed to be familial (Mayo Clinic, 2016). This disease causes rhythmic oscillation of body parts, most commonly wrist and hand, and sometimes head, voice, and legs. This tremor has a mild amplitude, with a high frequency between 8 and 12 Hz, and is visible. Alcohol or drug withdrawal. Symptoms of withdrawal refer to…

followed by a normal translunar injection about two hours later.[5][9]The engine shutdown was determined to be caused by severe pogo oscillations measured at a strength of 68 g and a frequency of 16 hertz, flexing the thrust frame by 3 inches (76 mm). The vehicle's guidance system shut the engine down in response to sensed thrust chamber pressure fluctuations. Pogo oscillations had been seen on previous Titan rockets, and also on the Saturn V during Apollo 6,[10] but on Apollo 13, they were…

Helen Thomson of the BBC reported on aphantasia, which is a condition where a person is unable to form mental imagery, or imagine things. Aphantasia fits into cognitive neuroscience, because it related to people’s mental perceptions. Cognition plays a role, but more in a lack of there of sense because people with aphantasia have the inability to creat images with their mind. In the article, Thomson reports about a person named Philip, who had no idea that people had the ability to create mental…

which distinguished by warm sea surface temperature in the equatorial region of the Pacific ocean. The Southern Oscillation (SO) is a change in air pressure between the western and central tropical Pacific. The pressure variability changes the strength of the trade winds, that results in affecting the surface ocean currents.. La-Nina and El-Niño are stages of the El-Niño Southern Oscillation (ENSO). ENSO is a series of consequent weather and ocean related phenomena. ENSO is also described by the…

PFC in mice exposed to an anxiogenic environment, implicating this circuit in behavioral inhibition, characterized by reduced exploration during anxiety 39. Conversely, impaired synaptic plasticity of this circuit is reported in another neural oscillation study that employed the chronic, unpredictable stress (CUS) paradigm to generate a depression-like phenotype 40. A recent fMRI study on patients with depression showed the Hippocampal-PFC connectivity is functionally impaired in correlation…
