• PSO Algorithm to generate test cases A. Initialize the population with N Particles where Program will search for optimal solution through the movement of these particles. And Set iterations counter I = 0. B. Apply Fitness function: Calculating the fitness value by calculating the percentage of this particle will share in minimizing the total processing time to find the optimal solution. C. Compare the calculated fitness value of each particle with its (lbest). If current value is better…

scavengers and predators obviously won't be able to preserve as fossils. Like the author has said, the animals existed back then had died and buried for such a long time, their bodies are rarely preserved. Only a very small fraction is preserved as fossils, and even smaller fraction are…

Organics polymers are emerging materials in various optical and optoelectronic applications due to their superior properties over conventional inorganic materials. For example, devices made out of organic polymers can be flexible, have better mechanical stability on impact, light weight and significantly effective in the cost of manufacturing. Due to these alluring properties, organic polymers are becoming extremely important in applications such as transparent/flexible optoelectronics,…

60-year-old male. D.B. was on 4SICU because he had a heart transplant on 1/24/17. However, prior to and after his heart transplant, he had various multi-system physical disruptions. D.B. had ischemic cardiomyopathy with an ejection fraction of 25%. The normal ejection fraction lies somewhere between 55-75%. In 2010, the patient had an implantable cardioverter defibrillator (ICD) placed. In 2014, a ventricular assist device (VAD) was placed as a bridge to transplant. He was considered an…

The basic principles are simple; the X-sperm contains more DNA than the Y-sperm. Although this difference is small, it is possible to measure DNA content of individual sperm with sufficient accuracy to distinguish between X- and Y-sperm with about 90% accuracy for 50% of the sperm. Therefore, about half of the sperm are discarded as unsexable. The DNA content of sperm is determined using a fluorescing dye, Hoechst 33342 that readily penetrates the sperm cell membrane and binds to the DNA…

The trail of tears was a series of forced relocations of Native American Nations.The nations that were relocated were Cherokee, Muscogee,seminole,Chicksaw, and Choctaw. The reason that they were relocated was because president Thomas Jefferson believed Indians should’ve been civilized. Jefferson also wanted to convert them to Christianity. In 1791 a series of treaties between the United States and the Cherokees, the treaties gave recognition to the Cherokees as a nation with their own laws and…

doesn’t know the words and said he listens to his father read while he doesn’t understand what the books are about. The father makes no inquiry of the child. During the homework observation, the child does fractions. The father indicates that he did not know the child was studying fractions. He understands his math…

time efficient than animal testing. For example, “The traditional testing of chemicals using animals can take up to five years per substance and cost millions of dollars, while non-animal alternatives can test hundreds of chemicals in a week for a fraction of the cost” (“ Alternatives in Testing”). This evidence clearly proves that there are better alternatives that are proven to be more cost and time…

Participants Participants were prospectively recruited from the cohort of consecutive patients referred to the Combined Head and Neck Clinic (CHNC) at a large tertiary hospital in Brisbane between September 2013 and November 2014. For inclusion, all patients had to have at least one parotid gland affected by either primary, metastatic or recurrent disease, and were planned to receive either definitive XRT or surgery with postoperative XRT to a prescription dose of 60Gy or greater. Patients were…

Methods Column chromatography was set up using a 60 ml syringe clamped to a ring stand. The syringe was plugged using a small amount of cotton. An Erlenmeyer flask was placed underneath the column to collect any excess material. Eleven 20 ml vials were labeled numbers 1 through 11. Silica gel was measured to 42 ml using a graduated cylinder and then moved into a 150 ml beaker. A slurry was created by adding 50 ml of hexane to the beaker containing the silica gel. The slurry was stirred for…
