endoplasmic reticulum, increase the rate and efficiency of enzymatic reactions in beef and lamb muscle; and also cause a selective heating effect on collagen .One study states that sonication of beef muscle with an intensity of 2 W/ cm2 for 2 h at a frequency of 40 kHz resulting in damages for the perimysium and improved texture. To notice the changes in maturation, applied ultrasound (20 kHz, 22 W cm− 2) for 0.5 -10 min and ripened for 1, 6 or 10 days. The sonicated muscles resulted in hardness…

transfer takes place at a particular wavelength its corresponding radio frequency is recorded, and when the spin returns to its base level, energy is emitted at the same frequency. The signal that matches this transfer is measured and examined in order to yield an NMR spectrum for the nucleus in question. The spinning nucleus has a magnetic moment whose relative values along with the angular momentum helps us to find the frequency at which energy can be absorbed. HOW DOES A NMR MACHINE WORK?…

electrode with the assembled glucose oxidase, Ag/AgCl, and a Pt wire as the working electrode, reference electrode, and the counter electrodes, respectively [13]. The following parameters were used to measure EIS using a Nyquist plot: start frequency, 20 Hz; end frequency, was 0.01 Hz; and amplitude voltage, 10 mV. The resistances…

had a low urbanization rate and low frequency of wars. The frequency of military conflict in China was 85% lower than Europe during from 1350 to 1800. Not only less war caused the little mortality, but the less natural obstacle also leaded a convenient way to trade, so there was little disease. Besides these, China’s fertility exceeded the mortality. Therefore, China was an opposite case of Europe to prove the Malthusian cycle. The high birth rate, low war frequency and low death rate caused low…

ECE-669c INDEPENDENT SUDY ON FIBER OPTIC SENSORS Mr. Prasanna M.Thawale School of Computer science and Engineering, California State University Northridge, Northridge-91324. Independent Study On Fiber Optic Sensors  Overview: Term: Fall-2014 Guide: Prof. Nagwa Bekir Topic: Fiber Optic Sensors .  Introduction: Fiber optic sensor since their emergence have been a sector of keen interest for researchers because of their specific and exclusive characteristics thus resulting into the…

Aim The aim of this practical is to measure the speed of sound using the resonance method. Variables Independent: Frequency Dependent: Length of Tube Constants: Temperature Diameter of Tube Theory The general equation used for finding the speed of a wave is v=fλ, as v∝f and v∝λ. The goal of this experiment will be to find v, the speed of sound. The only given is f, the frequency emitted by the tuning fork, however the wavelength, λ is not given. This value is derived from the length of the…

Exercise 1a reproduced the outcome of 30 beetle population size that has a ratio of 1:1:1 in red, orange and yellow phenotypes and indistinguishable predation ratio (1:1:1) over 20 generations. 3 trials out of 4 showed an analogous trend, the highest frequency of alleles is the yellow phenotype after the 14th generation in trial 2 and 3 and 13th generation in trial 4, making the overall surviving beetle population by 20 generations. The red beetle population showed a drastic extinction after the…

we have usually low temperatures in the winter and high temperatures in the summer, and intermediate temperatures in the Spring and Fall. Ultimately, climate has been changing with warmer winters, longer summers, increase of storm intensity and frequency.…

the individual’s ability to survive and reproduce. Harmful mutations can cause the organism to fail at reproducing which deletes that mutation from the population’s gene pool. Beneficial mutations have the opposite effect, resulting in a higher frequency of the specific mutation in future populations. Mutations accumulate in species over time until they amass into a distinctly new species. Natural Selection is the process proposed by Sir Charles Darwin in which beneficial mutations are…

physical geography theories learned in class so far, it can be asserted that precipitation varies throughout the state of Florida. Indeed, there are many factors that influence precipitation levels: convection, cold fronts, proximity to the ocean, and frequency of hurricanes. Of course, these are not the only factors that influence precipitation levels, but they are a major part of the process. According to Christopherson and Birkeland (2015) “When an air mass is lifted, it cools…
