Good essential oil recipes or essential oil blends can heal the physical body and bring wholeness and health to body, mind and spirit. What constitutes an "essential oil recipe?" In aromatherapy, when we create a recipe we are actually blending various oils together for a particular purpose. All essential oils have the power to affect us emotionally and spiritually but only those that are right for the individual at this particular juncture in their healing process will possess the subtle…

Purifying DNA to Estimate its Purity using PCR Amplification of VNTR to Load and Run Agarose Gel Introduction The study of this experiment was the Dopamine transporter gene. This gene is associated with different brain disorders like bipolar, as well as certain behavioural traits such as ADHD.[1] Dopamine transporter gene is a presynaptic plasma protein containing different VNTRs in it’s UTR and plays an important role in restricting the activity of dopamine by rapid reuptake into the…

1.4.9 Kinetics and metabolism Polycyclic Aromatic Hydrocarbons are lipophilic compounds that are readily absorbed from the lungs following inhalation, the gastrointestinal (GI) tract following ingestion and the skin following dermal exposure (ASTDR, 1995). In humans, it was reported that B(a)P measured in the lungs following inhalation of soot particles was much lower than expected. This may be due to the ability of the pulmonary epithelial cells to metabolise B(a)P thereby facilitating its…

As shown in Figure 1, carbon dioxide was added to a beaker with a pH of 7. We observed that a good indication of a higher pH level than 7 would be a change in color. The liquid was comprised of phenol red, NaOH, and Carbon dioxide. If the liquid turned yellow, the pH was below 7. Acidosis, a declining blood pH, is an indication the levels of acid in your blood are too high and there is weakened Hb oxygen bonding. This would be considered a medical…

materials, but they use bio-based plastics such as polyethylene, polypropylene, thermoplastic starch, polylactides and other plastics. The bioplastics used in their toys has greater strength than plastic, which increases toy safety. The toys are free of phenol, plasticizers, PVC, chlorine and…

Many people’s lives are put on the line everyday because they do not get themselves or their children vaccinated. This is due to the anti-vaccine movement here in America. Although some people believe they should not get themselves or their children vaccinated, in reality you should get vaccinated. People should get vaccinated because of the dangers of measles, meningitis, and that children are more prone to terrible diseases. One of the many reasons to get vaccinated is because of the grave…

examined the hearts they froze them in liquid nitrogen immediately after they extracted it from the mouse’s body. They than crushed and weighed the hearts. ATP was then extracted from the tissue. They than mixed a sample of chloroform and saturated phenol, than they were centrifuged at 10,000xg for 5 minutes. After the…

discovered a method to extract benzene from coal tar. Since its industrialization, benzene is produced and used in many industrial processes. Today, plastics, resins, dyes, implies the generation of benzene as intermediate. Also, chemical synthesis of phenol, cyclohexane, ethylbenzene and other aromatic hydrocarbons generates benzene as part of their production. In 1989, the Environmental Protection Agency of USA estimates…

Chapter 3 Process description and modeling 3.1 Process Description of Propylene Glycol Production Process The physical properties of propylene glycol are colourless and clear syrupy liquid when exists at room temperature. Besides than in liquid form, it also may exists in vapor form in air. In order to produce a colourless and odourless chemical, propylene glycol (C3H8O2, PG) involve in the reaction of propylene oxide and water. This involve the process of the hydrolysis of propylene oxide…

The theoretical yield of acetylsalicylic acid in grams that should be obtained from the synthesis is 3.96 g. The closest experimental yield was obtained without using a catalyst for the reaction; with a yield of 3.67 g (93%) of crude acetylsalicylic acid and a yield of 3.39 g (86%) of recrystallized acetylsalicylic acid. These results are relatively accurate. Similar results were obtained for the experimental yield of the reaction catalysed by concentrated sodium hydroxide; with a yield of 3.38…
