BATTERY BANK THE CHEMISTRY According to (Wikipedia, 2016), the deep-cycle battery is a type of lead-acid battery designed to be regularly deeply discharged using the majority of its capacity (45% - 75% depending on manufacturing and construction). These batteries are able to be cycled down to 20% charge, but the best cost vs lifespan method is to keep the average cycle at approximately 45% discharge. There is an indirect correlation between the number of charge and discharge cycles the battery…

Cleaning equipment, especially transducers, is something sonographers should be very conscious of considering they could be potentially spreading germs from patient to patient if the transducer is not properly cleaned. “Ultrasound transducers and coupling gel provide potential vectors for pathogen transmission, especially in immunocompromised…

Canker sores are small sores that occur on the inside of your mouth and cheek. CAUSES RISK FACTORS Risk factors include: • Gender. Women are more likely to get cancer sores than men. • Family history of canker sores. SIGNS AND SYMPTOMS DIAGNOSIS Canker sores may be diagnosed by medical history and physical exam. If you have get canker sores frequently, you may also have: • Blood tests. • Allergy tests. • Culture taken of the sore. This tests can help your health care…

The closing event is when the students present one of their products. A ticket out the door gives the teacher feedback on the assignments in the unit, the learning module, its effectiveness, changes necessary and thoughts on teacher performance. Based on the feedback, the students thought that the unit meaningful and worth completing. They particularly enjoyed the case studies and argumentation as well as creating authentic extension products. The case studies went particularly well due to a…

Designer Babies Designer babies allow parents and doctors to select gender, eye colour, and hair colour. It was originally screened for diseases in the baby. Doctors are tried to isolate the physicals genes of the baby. There are two types of advanced reproductive technology that are allowed on humans the first one is (I.V.F) in vitro fertilisation .Using in vitro fertilisation it allows doctors to reduce the risk that the baby will be born with a genetic disorder. I.V.F allows doctors to…

prevent hijacking on planes (Airport Security Strategies). Patrick Smith argues that the TSA has the wrong mindset because security regulations and screenings currently in place are too focused on searching for pointy objects, shoe removal, and liquids/gels. These methods are self-destructive because with the majority of security measures focused in airports dangerous people or weapons are still a risk if they slip past the weak security screenings and board the aircraft. Moreover, the present…

In lab, a sample of crude caffeine was purified using the technique of sublimation. Thin layer chromatography (TLC) was used to verify the caffeine's chemical structure and purity. Sublimation played a huge role in the purification of the crude caffeine. The process of sublimation is to take a chemical and change it from a solid phase directly into a vapor. Another reason as to why sublimation was used is because the caffeine can be separated from its contaminant due to the fact that it does…

A process that can turn a single copy of a gene into more than a billion copies in just house is calles the polymerase chain reaction(PCR). PCR allows medical researchers to make many copies of a gene whenever they want to genetically engineer something. The DNA structure for years has been relatively challenging to study. Ultimately DNA is very long and tiny. Luckily there has been many advancements in DNA technology that have made working with DNA much easier. Especially in the tools and…

Chemistry is the field of science involving structures, composition, and properties of substances and matter in order learn how they interact with each other. However, disposing and making chemicals can cause hazard to the environment and wildlife. In “Chemistry: Green and Clean,” Jennifer Weeks builds an argument to persuade her audiences that green chemists are working cooperatively to develop a field of chemistry that can replace polluting technologies. Weeks uses alternative ways to…

MBA is used as a crosslinker for reaction. At lower crosslinker concentration, the gel may have less crosslinking and hence higher swelling capacity. Whereas the gel formed with high crosslinker concentrations will possess higher crosslinking density causing decrease in the distance between the crosslink points lowering the swelling capacity [13]. From the figure 5 we observed…
