“If you’ve seen one, you’ve seen them all,” remarks Kathy Selden about movies after first meeting silent film star Don Lockwood in the beginning of Singin’ in the Rain (Singin’ in the Rain 17:38). While Kathy was slightly off base when saying that all movies are the same, movies belonging to the same genre often do share certain conventions which author Bernard F. Dick discusses in his book Anatomy of Film and Tim Dirks confirms in his assessment of the genre for the American Movie Classics Company

We investigate and experimentally demonstrate the elastic wave filtering properties of graded undulated lattices. Square reticulates composed of curved beams are characterized by graded mechanical properties which result from the spatial modulation of the curvature parameter. Among such properties, the progressive formation of frequency bandgaps leads to strong wave attenuation over a broad frequency range. The experimental investigation of wave transmission and the detection of full wavefields effectively

Differential effects of antipsychotics on the development of rat oligodendrocyte precursor cells exposed to cuprizone Abstract Cuprizone (CPZ) is a copper-chelating agent and has been shown to induce white matter damage in mice and rats. The compromised white matter and oligodendrocytes (OLs) respond to some antipsychotics in vivo. However, little is known about the effects of antipsychotics on cultured OLs in the presence of CPZ. The aim of this study was to examine effects of some antipsychotics

MacConkey Agar plate Extremely similar to Eosin Methylene Blue Agar, MacConkey Agar is a selective and differential media used to isolate organisms based on their lactose fermentation ability. It contains lactose, bile salts, neutral red, and crystal violet (Leboffe, A Photographic Atlas for the Microbiology Laboratory). Just like the Eosin Y and Methylene Blue dyes in the EMB plate, the bile salts and crystal violet in the MacConkey plate encourage the growth of Gram-negative bacteria while preventing

As usual Chaplin plays his famous character , the tramp , a dim-witted under dog. He is a lone prospector who falls in love with a dance hall girl. Chaplin effectively

Transparent Synthetic Soils Transparent porous media are increasingly being used to study soil contamination in geo-environmental subsurface research because they permit visualizing flow conditions away from the model boundaries, inexpensively (Manheimer and Oswald, 1993; Welker, 1999). Transparent porous media representing a wide range of natural soils have been developed (Iskander, 2010). Transparent synthetic “soils” (Fig. 1) are made by matching the refractive index of solid transparent particles

The Gram-negative bacterium for Unknown 13B was Salmonella typhimurium. Unknown 13B had similar reactivity patterns to S. typhimurium. A comparison of Unknown 13B and S. typhimurium can be compared in Table 2. The Catalase test and the Methyl Red test for Unknown 13B and S. typhimurium both obtained positive results (Table 2). Negative results were acquired through the Indole test for Unknown 13B and S. typhimurium (Table 2). For the Lactose Ferment and the Sucrose Ferment test, negative reactions

In this experiment, we wanted to investigate which surfaces in the school had the most bacteria, and we thought that the surfaces used more would have the most bacteria. For this experiment we used agar plates, cotton swabs and distilled water in order to see how much bacteria was on each surface. Cotton swabs were wet with distilled water and then the swabbed ws wied on a 2 inch space of the surface and twisted to cover the entire swab.once we swabbed the surface, we wiped the swab on the plate

Procedure: 1. Find a clean counter or table to work on. Make sure you have everything you will need and that all of the items are clean. 2. Put on a pair of disposable gloves. 3. Make a paper towel damp with some 70% isopropyl rubbing alcohol. Wipe down the work surface with the rubbing alcohol-dampened paper towel. 4. Using a permanent marker, label the five baby food jars #1 to #5. 5. Perform a 1:10 serial dilution of the colloidal silver. Notice that the bottle you purchased is labeled

How does the addition of pGLO plasmid to a solution containing E. coli bacteria affect the growth and characteristics of the bacteria? Genetic transformation is the incorporation of foreign DNA into an organism to potentially change the organism’s trait. Plasmids are small circular DNA that replicate separately from the bacterial chromosome. In nature, these plasmids can be transferred between bacteria allowing for the sharing of beneficial genes. Due to this characteristic, plasmids allow for genetic
