By varying the carbon content, cooling rates, we will get different microstructure of steels that yield different properties which can be tailored to meet different engineering applications. In this experiment, the hardness of 3 steel alloys with varying Carbon compositions will be compared. With different amounts of Pearlite formed, we can also estimate the hardness of pure pearlite and ferrite. Lastly, the fourth sample will be quenched in water and a Martensitic structure will be observed. We

Abstract: The term dependable (examination and) advancement has increased expanding EU arrangement significance in the most recent two years, specifically inside of the European Commission 's Science in Society program, in the Horizon 's setting 2020 Strategy. We give a brief verifiable diagram of the idea, and distinguish three particular components that are rising up out of related talks. The principal is an accentuation on the equitable administration of the reasons of exploration and advancement

Human breast cancer MCF-7 cells were obtained from American Type Culture Collection (Manassas, VA, USA). The cells were maintained in RPMI 1640 medium supplemented with 10% FBS, 2 mM L-glutamine, 100 U/mL penicillin, and 100 mg/mL streptomycin at 37 °C in a humidified atmosphere with 5% CO2. Cell viability examination To evaluate the cytotoxic ability of WECU, MCF-7 cells were seeded in 6-well plates at a density of 2×104 cells per well. After incubating overnight, the cells were treated with

The complex [Pd(HL)2Cl2] (C3) was synthesized as follows: A solution of 1.4000 g (5.64 mmol) of imine (L3) in methanol (20.0 mL) was slowly added dropwise to the solution containing 1.0000 g (5.64 mmol) of palladium(II) chloride and 0,4748 g (11,28 mmol) of lithium chloride dissolved in methanol (50.0 mL). The resulting solution was stirred at room temperature for 8 h. The obtained yellow precipitate was filtered off, washed with ethanol, water and ethylic ether, and then dried under vacuum. Yield

The hemocytometer is a device used to count cells. It was originally designed for the counting of blood cells. It consists of a thick glass microscope slide with a rectangular indentation that creates a chamber. This chamber is engraved with a laser-etched grid of perpendicular lines. The device is carefully crafted so that the area bounded by the lines is known, and the depth of the chamber is

How are the special properties achieved in glass Ethan Francke Introduction Glass is a vey common material used in everyday life and can be seen nearly everywhere you look. It can be found in; houses, class rooms, smart phones, glasses, microscopes, light bulbs etc. Even though it’s found nearly everywhere glass is used for various objectives and purposes. Glass itself is made by melting sand which is mostly composed of Silicon Dioxide at about 1700oC (Chris Woodford, “Glass”, 13/12/2017)

The authors hypothesized that fluorescent indicators would be useful tools in recording brain activity because they would allow monitoring of a genetically defined neuronal circuit and they would not require chemical access to visualize and provide optical recording of brain activity. Since the current techniques could not meet the authors’ requirements to study neuronal activity in vivo, they sought out to create a voltage

Gold nanoparticles in breast cancer treatment: antibodies and aptamers Nasirli Ilkin University of South Florida PHA6146.002F17 Nanotechnology Abstract Cancer has a major impact on societies world-wide. In 2011, an estimated 1,685,210 new cases of cancer were diagnosed in the United States, and approximately 595,000 people died from the disease (DeSantis et al 2011). Breast cancer is the second most common type of cancer for women in the United States (US). The biological usage of nanoparticles

A. SIGNIFICANCE. Our goal is to screen chemical libraries to identify compounds that modulate mitochondrial transport in hippocampal and cortical neurons. This study is significant in four ways: (1) There is an urgent need to develop CNS (Central Nervous System) active drugs. CNS disorders are not only staggeringly complex but are poorly treated diseases (Palmer and Stephenson, 2005). In the United States alone the annual cost for stroke, depression, Schizophrenia and Alzheimer’s disease are currently
