DABARKADS “ WITH HAND MOVEMENT AND DANCE STEPS. PART 1 LECTURE SURGICAL SCRUB‚ surgical scrub is the removal of as many bacteria as possible from the hands and arms by mechanical washing and chemical disinfection before taking part in a surgical procedure . Purpose: Surgical Scrub helps prevent the possibility of contamination and infection of the operative wound by bacteria on the hands and arms. TWO PROCESS 1.MECHANICAL PROCESS -The process to remove soil and transient microorganism with

The Gram Negative lab had two parts; the aim of the first part is to determine the concentration of gram negative bacteria in a water sample collected from a creek near Providence Road‚ Strickling. Gram negative bacteria have a cytoplasmic membrane‚ a thin peptidoglycan layer‚ and an additional outer membrane composed of phospholipids and lipopolysaccharides. Because gram negative bacteria have a relatively thin cell wall when compared to gram positive organisms‚ they are consequently unable to retain

has be highlighted as very important‚ more so than it used to be as more and more people are suffering from heart diseases as a result of fatty deposits building up. Staying on the topic of food‚ the process of fermentation requires the use of bacteria which is a microbe. A big example of this is the production of bread which uses yeast to make the bread rise. This works as it is aerobic respiration so gives off carbon dioxide‚ making the bread rise. Another use of yeast is in anaerobic respiration

there were about 40 cases reported each year‚ half of which are associated with women using tampons." [1] Staphylococcus aureus are anaerobic‚ gram positive bacterium. They lie harmlessly in the mucous membrane of the vagina. Though‚ the bacteria can grow rapidly if the tampon is left in the vagina for an overextended period of time. This is being due to the warm conditions and viscous fluid present at the time. Bacterial invasion depends on the way the tampon has been inserted into the vagina

Question: Suppose a meteor impact blows some extremophile bacteria from the Earth into the depths of a gas giant planet called planet X ‚ where they evolve into an intelligent species which practises physics. Do you think their physical theories would be similar to ours‚ and if so in what ways would they be likely to be similar? Your answer will necessarily involve some speculation‚ but make sure it involves some careful argument as well. Theoretical physics is one of many braches of physics that

I had # 8 organism‚ Bacillus subtilis. Bacillus subtilis is a Gram-positive bacteria‚ rod-shaped and catalase positive. In order to figure out what is my unknown organism for this assignment‚ I had to perform series of tests. First was the glucose‚ lactose‚ and sucrose test. Through these three tests‚ I was able to detect the ability of the microorganism to ferment a specific carbohydrate. Fermentation reactions are observed by the color change in pH. In class‚ we used phenol red as the pH indicator

Materials: 1-Tube containing unknown bacteria‚ crystal violet‚ iodine‚ decolorizing agent‚ Safranin‚ Bunsen burner‚ sheep blood agar plate‚ TSA plate‚ and bacitracin antibiotic disks. Procedures 1: 1.) Obtain a tube with an unknown bacteria and materials necessary to prepare a gram-stain. 2.) First place 5-8 loops of the bacteria onto the slide in a circular area and heat fix the bacteria to the slide. 3.) Place 3-5 drops‚ or enough to cover the bacteria‚ of crystal violet stain onto

They have three main functions on the skin‚ the first is to prevent colonization by pathogenic strains because they limit the space for other pathogens‚ the second is that they produce vitamins‚ finally‚ it also helps in metabolism. 6) Who does dsRNA interact with Toll Receptor 3 and why is it found in the endosome?

This strain of bacteria‚ according to studies and research‚ is confirmed to be inhibited by organic compounds produced and contained in extracts of kamias leaves and garlic bulbs. These two organic products are commonly used in adding flavor to food and they both exhibit their antibacterial properties on the same strain of bacteria. So‚ this study aims to

Wastewater can come from a variety of sources like homes‚ businesses‚ industries‚ runoff from roads‚ lawns and fields and is treated by municipal wastewater treatment facilities (Product‚ cornell). The solid material that remains after the treatment of wastewater is known as sludge (charac‚ cornell). Sludge can be employed in many different ways‚ it can be used as a soil additive or growing medium‚ sent to a composting facility‚ incinerated or landfilled (Char‚ cornell). Biosolids are derived
