Chromosomal instability is a central feature of many tumours and is present in about 85% of colorectal tumours. It is characterised predominantly by frequent chromosomal abnormalities which include translocations, gains, and losses of entire chromosomes or their segments [Grady, 2004; Baba, 2009]. Although the causes of chromosomal instability are still poorly understood it is thought to arise as a result of mutation and amplification of a number of genes including Aurora-A, encoding a serine-threonine
The 21st Century Electric Car By Martin Eberhard and Marc Tarpenning Tesla Motors The electric car, once the “zero-emissions” darling of environmentalists, is sometimes maligned as an “emissions-elsewhere” vehicle, since the electricity to charge its batteries must be generated in electrical generation plants that produce emissions. This is a reasonable point, but we must then ask how much pollution an electric car produces per mile – accounting for all emissions, starting from the gas
Romar M. Cabinta EXERCISES 15 WORK, ENERGY, AND POWER A. CONCEPTUAL QUESTIONS 1. Is work done when you move a book from the top of the desk to the floor? Why? Yes. It is because the displacement of the book from the top of the desk to the floor and the force that is applied to the book is parallel with one another. 2. State the law of Conservation of Mechanical Energy in two ways? The law of conservation of energy states that energy may neither be created nor destroyed.
Introduction Experts believe that terrorist use of chemical agents is an event with low probability, but potentially high consequences. While terrorist groups may or may not have an increased interest in chemical agent acquisition and use, the domestic vulnerability of the United States to chemical attack remains an issue. Both the United States and Russia have signed and ratified the Chemical Weapons Convention (CWC), and are reducing, and eventually eliminating, their chemical weapon stockpiles
is difficult to determine the surface of this star, as it has a density of 0.000010 kg/m3 , less dense than the atmosphere of the Earth at sea level. This red hypergiant is approximated to undergo a supernova explosion within the next 100,000 years. VX Sagittarii is a red hypergiant that is 4,900 light years away from Earth located in the constellation Sagittarius. Although uncertain, the radius of this star ranges anywhere from 1,300 to 1,900 solar radii. Sagittarii is a pulsating variable star,
currents) from stationary reference frame to torque and flux producing currents components in rotating reference frame. The vector control of the PM synchronous motor is derived from its dq dynamic model. Considering the currents as inputs, the three currents are: ia = Is sin (ωrt + α) (4.12) ib = Is sin (ωrt + α - )
392 degrees Fahrenheit, and is heavier than water, but soluble (CDC 2014, Table 1). Consequences Medical effects of soman are typical of nerve agents, and likewise varies depending on the extent of exposure. Specifically, GD is more volatile than VX, but less volatile than sarin (CDC 2013). While the severity and timeliness of symptoms depend on the exposure, the symptoms include: change in blood pressure, blurred vision, chest tightness, drowsiness and confusion, cough, diarrhea, excessive drool
QA Gone Wrong: Level 3 Military Lab Mistakenly Ships Live Anthrax Spores The Dugway Proving Ground is a US Military Level 3 biodefence laboratory that was opened in 1942 by President Franklin D. Roosevelt. It was opened after the attack on Pearl Harbour for the purpose of testing chemical and biological warfare weapons. In 2001, after the 9/11 attacks and the anthrax mail attacks it was assigned the task of researching anthrax (Burns & McCombs, 2015). In 2015 it was found that the lab mistakenly
A chemical weapon is defined by the Organisation for the Prohibition of Chemical Weapons as “...any toxic chemical or its precursor that can cause death, injury, temporary incapacitation or sensory irritation through its chemical action. Munitions or other delivery devices designed to deliver chemical weapons, whether filled or unfilled, are also considered weapons themselves.” (http://www.opcw.org/about-chemical-weapons/what-is-a-chemical-weapon/ ) Chemical Weapons (CW) are classified as Weapons
and to create electric field lines by providing an electric current through carbonized sheets. Once we have completed constructing the electric field lines for the plate charge distribution, we will continue to calculate for the electric field (E = Vx) and begin to plot for the dipole charge distribution. When we have collected all the data needed, we then will finish calculating for all the remaining variables and complete the rest of the lab report. Procedure
