Vertical root fracture is the one of the most critical complications of endodontically treated teeth which can take place before, during or after root canal filling and can end up with tooth loss (1, 2,3). Exaggerated loss of tooth structure due to trauma and caries, dehydration of dentin (4), access cavity preparation, mechanical preparation (5) and irrigation (6) of the root canal, and post space preparation are critical factors that would influence the durability and strength of root canal…

The experiment calls for the extraction and purification of a protein. The protein chosen for the experiment was an amylase, specifically beta-amylase. Amylase protein can be typically found in plants and animals. The role of this protein is to hydrolyze organic materials, such as starch and dextrin, in order to form glucose, maltose, and limit dextrin. One distinction between beta amylase and alpha amylase is that beta amylase is not found in animal. It is found primarily in plants, bacteria,…

“The primary endpoint was met by 5% of patients in the medical therapy group, as compared with 38% of those in the gastric bypass group and 24% of those in the sleeve gastrectomy group” (Yafi, M. 2014). 2. Medication schedule: Magnesium hydroxide/aluminum hydroxide (Mylanta) 15 mL PO will be scheduled at 06:00 AM, 11:00 AM, 05:00, and 09:00 PM, Ranitidine (Zantac) 300 mg PO at 09:00 PM, 60 minutes before meals, while Sucralfate / Carafate 1 g or 10ml suspension (500mg / 5mL) will be scheduled at…

Magnesium Magnesium is one of the best elements you can own it’s a 3rd period element its part of the alkaline earth metal family. Magnesium is a metal and it’s a solid, with a isotope of 24 and really high energy level. Buy magnesium it’s going to be your favorite purchase you will ever make you won’t regret it. Magnesium was discovered in 1808 by a guy named Sir Humphrey Davy but it was first experimented by joseph black. The Country it was discovered in was England in the United Kingdom.…

These are created from the dissociation of the hydrogen ion in organic matter, and hydrogen ions being added and removed of the alcohol (OH) group on mineral surfaces. The amounts of charge changes due to the pH, as the concentration of hydrogen and hydroxide ions determine the pH. This relates to soil solution acidity. How acidic the soil is shown by the concentration of hydrogen ion there are within the solution. Therefore, the higher concentration of OH- will have a higher pH- more alkaline.…

production, product manufacture, product use and waste management (Sun et al., 2017). Lithium is extracted from two sources - ore and salt brines - and the lithium minerals are then transformed into basic chemicals such as lithium carbonate, lithium hydroxide, and lithium chloride to produce many derivatives (Sun et al., 2017, p. 51-52; Wanger, 2010; USGS, 2018). Originally, the majority of lithium was produced from mineral ore sources - spodumene, lepidolite…

At the beginning of the 1900s chlorine started to be used as a disinfectant in water. Water had to be chlorinated because of waterborne pathogens which would then go and cause deadly diseases which flourished in our pipes and water ways and infected millions of people. But ever since the disinfection of water the most of these diseases have been eliminated in first world countries but is still a big problem in 3rd world problems. (Calomiris, 1998) Chlorine is the most used disinfectant around…

results that were being acquired. In the electrolysis there is a flow of electrons from the positive to the negative electrodes. From the anode to the cathode. From the graphite to the copper. The cations in this experiment which is the sulphate and hydroxide will migrate to the negatively ions or cathode copper . Positive ions are attracted to the negative electrode, gain electrons so are reduced. This is…

Practical 3: Enzyme Activity (2.5) Research Question: How does the change of pH affect the rate of decomposition of hydrogen peroxide on the enzyme, catalase? Background Information: Enzymes are globular proteins, which are synthesised by cells in order to perform specific functions. These act as catalysts in chemical reactions and are considered a major factor in an organism as these reaction rates are required to be shortened in order to support life. Catalase is one of the most…

water. Materials and Experimental Procedure A stock solution was prepared using 99.27 g of sodium thiosulphate (Na2S2O3•5H2O), sodium hydroxide (for pH adjustment) and 145 mg of silver sulphate (Ag2SO4). The sodium thiosulphate was dissolved in distilled water to produce a 0.4 M solution in slightly less than 1000 ml volume. The pH was adjusted to 9.5 by sodium hydroxide. Distilled water was added to bring the final volume of 1000 ml. The mentioned amount of silver sulphate was dissolved in…
