Voltage source

step was to use the micropipette and provided tips to fill up each well with 35 uL of each sample in their separate wells. Everything was checked to make sure everything was properly done. Electrodes were hooked in their desired locations, power source was provided to the gel box, and timer was set for 15 minutes. Upon completion gel was properly stained, and the light box was used to visualize the gel for clear results. Main safety issue during this experiment was to be very careful with the…

Keystone XL is a pipeline that will carry crude oil from Alberta, Canada’s tar sand oil reserves to Nebraska and Texas where the crude oil will be refined. This pipeline was first proposed in 2005 by the TransCanada Corporation, and the extension that we know as Keystone XL was proposed in 2008 where its purpose was to increase American jobs in the Midwest as well as decrease our dependence on foreign oil supplies. This pipeline has been surrounded by controversy since the genesis of the…

The SEM produces a largely magnified image by using electrons instead of light to form an image. A beam of electrons is produced at the top of the microscope by an electron gun. It consists of an electron gun to produce high energy electron beam. A magnetic condensing lens is used to condense the electron beam and a scanning coil is arranged in-between magnetic condensing lens and the sample. The electron detector (Scintillator) is used to collect the secondary electrons and can be converted…

only we, the public, must follow, but also everyone else in the hospital. Failure to abide these rules and regulations can pose harmful threats and sometimes even results in death. It is important to educate and remind the users and staffs about the sources of threats and safety of the hospital environment. There are many kinds of threats that can arise in the hospital but we will be explaining in details the following 10 factors: Natural Environment, Chemicals & Drugs, Microorganisms & Vermin,…

acetylcholine receptors (nAChRs), which are ligand-gated ion channels. When a cholinergic agonist binds to the outside of the channel, the channel opens, allowing the entry of cations, including sodium and calcium. These cations further activate voltage-dependent calcium channels, allowing further calcium entry” (Benowitz, 2008). In the human brain, the most abundant nAChR subtype is the α4β2 nAChR (Benowitz, 2008). This nAChR subtype is reduced in the brains of patients suffering from AD (Okada…

Charlie Murphy ctmurph2 The Science Behind Hydropower Plants The Condit Dam, constructed along the White Salmon River in South Central Washington, was created in order to power the Crown Willamette Paper Company nearby. Unfortunately, the salmon that inhabited the river were unable to pass through the dam, leading to its destruction nearly one hundred years later. As a result of its removal, the salmon were able to repopulate the river and thrive in the reestablished environment. Although…

Using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) images and spectra were obtained from various samples of silica and platinum on silica. Each sample contains unique structures which were prepared by etching the surface of silica in different conditions. A scanning electron microscope is a type of electron microscope that produces images of topography and composition by scanning a sample with a focused beam of electrons. Samples can be observed in high vacuum,…

It will act as a magnetic vacuum from buried copper coils in the ground that attracts particulate matter by a weak electrostatic field. "It 's high voltage, low amperage, and the more power you put in the more pollution you can attract" (Fairs, 2013, p. 1). Preferably the coils will be buried under grass lawns, which will make the remission of the pollution highly improbable. The purifier will get the…

Levofloxacin cocrystals were prepared by solvent evaporation method. The drug and co formers, stearic acid and sodium saccharin were physically mixed in varying ratios of 1:1, 1:3, 1:5, 1:7 and 1:1 and 2:1 respectively in a glass mortar and the mixtures were dissolved in ethanol as solvent for crystallization. The solvent evaporation was carried in rotary flash evaporator (Laborota 4000, Hiedolph) maintained at 40 ± 2ºC and speed of 30 rpm. The products obtained were dried in a desiccator and…
