Porous medium

Scientists use different types of nutrient agar media to help with the study of microorganisms. The purpose of this experiment was to examine the different growths of minority organisms within a variety of media cultures. These cultures included types of selective, differential, and enriched media and were applied to split sections on the agar plate. Each of the four broth cultures: Escherichia coli, Enterobacter aerogenes, Staphylococcus epidermidis, and Streptococcus faecalis showed observable…

Introduction: Sampling the microbial content of the environment is a recommended practice for hospitals and clinics. Information obtained by environmental sampling has great value in the evaluation of problems relating to housekeeping procedures, disinfectants, air distribution and filtering, traffic control and the influence of specific equipment on environmental contamination. The purpose of this practical is to assess the effectiveness of some cross-infection control measures commonly…

The film that I have chosen to analyze is Lessons of Darkness by Werner Herzog. I chose this film because I really enjoy Herzog’s film style, and I also enjoy how he uses specific shots and scenes to portray how he is against the gruesome nature of war and attacks. In this film, I have chosen two sequences where I believe that Herzog is trying to get his point across of the violence that come from war. For example, as Herzog uses the first sequence of the birds, to the bones of the dead, to the…

containing 9mL water using a pipette. Four MSA and four PEA plates were used for isolation. PEA plate number 1 was divided into three parts and was used to isolate all of the samples obtained from the skin by rolling the cotton swabs on the surface of the medium. PEA plate number…

Everyday millions upon millions of people head out with friends, family, or their significant others to go partake in a simple activity, watching a movie. There are tons of movies to pick from; they come in different languages with different genres and different stories to tell, but one thing they have on common are the messages that they send out. These messages can show up in one brief scene yet teach the audience so much about morals or issues around the world and create emotions within the…

Cream may have the potential for use as a probiotic carrier because it provides an excellent environment for probiotic bacteria, with the added advantage of having nutritional value.Fatty Acids composition in fermented synbiotic cream, containing one of the two probiotic bacteria ( Lactobacillus acidophilus, Lactobacillus casei ) and inulin (0,1.5, 3%) was evaluated during 30 days for the the15-day interval at 4±1 °C. All chemical characterization were affected by the probiotic bacteria strain…

This medium is able to successfully engage its audience throughout the video, which is a strength that is harder to maintain in something such as long-form journalism where the majority of it is written word. Also, a major strength and defining characteristic…

Aaminah Azhar Astrobiology Spring 2015 Test 1 1. Name and describe five important steps in the formation of planets based on our current scientific understanding. a) Star and planet formation starts inside a collapsing cloud of gas and dust inside a bigger cloud called a nebula. Because of gravity pulling materials in the collapsing cloud closer together, the center of the cloud gets increasingly more compressed and because of this get hotter. The dense hot core of this collapsing cloud becomes…

Planetary, supernova, dark, and reflective are all types of nebulae that are formed and act differently. The elements found in the planetary nebulae and supernovas. A scientist has found that in the permitted lines of planetary nebulae there are nitrogen ions (Aller). Permitted lines are only found with a high power telescope; this shows that there are more possibilities of other elements within these clouds. The elements that are mostly know in Planetary nebulae are the common “hydrogen,…

First the unknown tube was isolated. This was completed by taking an inoculating loop and spreading the unknown out on to a Nutrient Agar plate. This was done using the streak plate method, which is described in the lab manual. The bacterium were incubated and grown at 48 hours. Upon observation the isolation plate showed growth of two different colonies. After the morphology was observed and recorded, a Gram stain was performed on each of the two unknowns, this procedure is found in the…
