A fixed prosthesis for one tooth or even full mouth rehabilitation is been commonly certified for their reliability and durability. Despite of the conservative procedures of crown preparations, obstacles may occur in each step leading to pulpal exposure. In the past, endodontic treatment or even extraction of the tooth was the only solution to pulpal complications. A recent update shows that pulp capping that resists the death of the exposed or nearly exposed pulp can be explication to pulpal…

M.G. is a 10-year old African American female presenting to the clinic with her mother. She is clean and intact, well nourished and in no apparent distress. She has been getting allergy shots due to eczema, but the mother wishes to stop them due to lack of improvement in her condition. She had been prescribed with tea tree oils, which she used twice daily until it ran out three months ago. She has also been having daily baths with dove and herbal soaps and bath salts twice a week. She has also…

1. Introduction and background The experiment that will be conducted is the preparation of benzoic acid. Benzoic acid is a carboxylic acid and this has been established in the 16th century. The molecular structure of benzoic acid can be seen in the following figure. Figure 1 – Molecular Structure Benzoic acid is used to prepare esters with the very high boiling points and is used as plasticisers. Plasticisers are compounds that are added to plastics to…

Enterobacter spp. Enterobacter spp are part of the enterobacteriaceae family. They are facultative anaerobic gram negative bacilli. Their means of motility is by means of petrichous flagella. They produce acid upon glucose fermentation and are methyl red negative, voges-proskauer positive. Optimal growth temperature is 30*C .80% are encapsulated. E. spp have been associated with nosocomial outbreak and are opportunistic pathogens. They can cause numerous infections such as cerebral abscess,…

In electrolytic chlorination (i.e., electrolysis), an electrical current is directly applied to seawater generating free chlorine, sodium hypochlorite and hydroxyl radicals. During the electrolytic chlorination process, a certain salinity level in ballast water is required or additional salt will need to be added. The hydroxyl radicals generated in seawater quickly form disinfection byproducts…

Leaching of enargitite concentrate using sodium sulphide (Baláž et al., 2000). Alkaline leaching of enargitite using sodium hypochlorite under oxidizing conditions (Viñals et al., 2003). Ruiz et al. (2014) used the former to investigate the selective leaching of arsenic from enargitite by alkaline digestion. The process consisted of alkaline digestion with concentrated Na2S-NaOH…

ABSTRACT Elaeis guineensis is a species of palm generally called African oil palm, and it can reach the height of 20 m or more at maturity. The oil palm is major importance in Africa as a multi-purpose tree where it supplies medicines, foods and many other products to the local population. Elaeis guineensis is rapidly becoming one of the world's most planted plants, being grown especially for its oil-bearing seeds and fruits. Usually 23 kg is the average weight of each bunch but a bunch may up…

Introduction: The world of antiseptics and disinfectants is ever changing. There are many different options out there and people have to decide what is the best option for them. For the experiment we performed in class, we had a variety of different options to use to see what the results would be from these. The range of items used were from and everyday household product of Lysol to Iodine which can be used in the operating room to prep the patient for the type of surgery they are having done.…

Animals and humans have bacterial populations all over their body. However, the gastrointestinal microbiome is one of the most complex and dense populations studied (Todar, 2012). The mammalian gastrointestinal tract is comprised of about four million bacterial genes with more than 95% located in the large intestine (Galland, 2014). The gastrointestinal microbiota varies along the tract at longitudinal levels and horizontal levels due to particular bacteria attaching to the epithelium in the…

mays, var. B73) seeds were immersed in 0.5 % % sodium hypochlorite for surface-sterilization for two minutes, dipped in 70 % ethanol for two minutes and rinsed in sterile distilled water thrice. 100 μl of the last rinsing water was plated on potato dextrose agar (PDA) media, and incubated 10 days at 25 °C to ensure…
