Akhenaten is often not credited as being one of the great pharaoh’s of ancient Egypt; his name is not as recognized as his son, Tutankhamen. However he deserves acknowledged for being a revolutionary leader. Akhenaten is most well-known as being a spiritual enthusiast and instigator of revolution within the kingdom of Egypt. Many historians have recognized Akhenaten with being solely responsible for developing a religious revolution in Egypt. Nevertheless his struggles defined as the first true effort at instituting a monotheistic state in a polytheistic society, his efforts were not eternal. The reasoning behind his decisions to change Egypt's faith is still observed though to this day. “Today most historical resources believe Akhenaten

Creation stories are symbolic accounts of how the world and its inhabitants came about. These stories first developed in oral traditions, so there are multiple accounts of them from different cultures and societies. The Babylonian Creation story, the Genesis Creation story, and the Sumerian story of the Creation of Enkidu are examples of these and the similarities are interesting. As Dennis Bratcher states, “Because of many parallels with the Genesis account, some historians concluded that the Genesis account was simply a rewriting of the Babylonian Story. As a reaction, many who wanted to maintain the uniqueness of the Bible argues either that there were no real parallels between the accounts or that the Genesis narratives were

The ancient kingdom of Kush was a civilization of vast and advanced cultures and governments that lasted for approximately 1500 years. Throughout those years, the ancient Kush has developed and maintained various distinct features in order to control and adapt to its way of life. But to set ancient Kush’s records straight, we need to closely observe how they developed as an independent kingdom and their main features.

Mission statement: Our mission is to help people live healthier lives and to help make the health system work better for everyone.

We then created an ice bath using a 250mL Erlenmeyer beaker. The 50 mL Erlenmeyer beaker was then labeled as “Acid Extract”, and was placed in the

Cells are rinsed with chilled PBS, scraped into chilled PBS, and then centrifuged at 200 × g for 4 min. Discard the supernatant. The cells are now ready for lysis or storing at -80 ℃ for future use.

To tube 2 and tube 3 a boiling chip is added. The two tubes are boiled to remove any residual ether. Next, the tubes are cooled to room temperature and placed into an ice bath to allow for crystallization. The solution is then removed from the solid in each tube and discarded. To tube 2 and 3 ~0.5 ml of H2O is added for recrystallization, the tubes

When reflecting back to experiment 3, Aseptic Technique and Culturing Microbes, I realized the large amount of microorganisms that can be found in everyday life. Many different types are found with in the human body. Theses experiments focused on two types of bacteria. First was Staphylococcus epidermidis, found on the skin, and second was Lactobacillus acidophilus, found in the gastrointestinal tract. Both have similar needs for growth when it comes to temperature, however, different growth environments are used.

1.) Transfer the distillate to separatory funnel. Fluid didn’t seem very clear but sufficient to finish our lab on time.

After the mixture finished refluxing, the flask was then cooled on ice. A sulfuric acid solution was then prepared by pouring 4.5 mL of concentrated H2SO4 over 50 grams of ice and then diluted to 75 mL by adding enough tap water to reach 75 mL. The sulfuric acid solution was then cooled on ice.

Gioe Melaney is the general director of Southern Toro – a subsidiary company included in the distribution system of Toron Coporation in Galveston, Taxas.

Abstract – Yogurt is a product of lactic acid and lactose. In order to produce yogurt, milk is pasteurized (at 45 degrees Celsius) and the inoculum is added followed by incubation. Over a period of 7 days, yoghurt fermentation was attempted using lactobacillus cultures. A liter of milk was supplied and plain yoghurt was used as a starter culture as it contains the necessary bacteria to ferment lactose and produce lactic acid. The milk was added to a flask: then boiled, cooled and inoculated. The milk was incubated for a week and all the while the milk was tested for changes in pH, density, mass and physical changes. The values obtained were then used to determine the growth kinetics of Lactobacillus bulgaricus.

The procedure of this experiment started out by taking a hand boiler and beginning to warm up the bottom bulb with your hands, trying your best to transfer as much of the colored ethanol solution into the larger bulb as possible. After, with the boiler inverted, place the smaller bulb into a cup of ice water and let it sit for 10 – 20 minutes, allowing distillation to occur.

As stated, our solvent in this lab will be tert-butanol. We start by recording the freezing point of this substance without anything added. Then, we add various

The purpose of the two experiments was to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli, Pseudomonas fluorescens, Enterococcus faecalis, Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5, 25, 37, 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different species. After one week they were observed for distinguishable changes by the turbidity showing an indication of bacterial growth, or the clarity an indication of no survival.
