  1. Could you clarify that please? You want to know how to memorize the data about vitamins?
  2. Hi, those are not the same: Doubling dilution is a serial dilution effected so that the concentration in each tube of the particular cell, substance, etc. of interest is half that in the preceding tube of the series. Whereas serial dilution is the stepwise dilution of a substance in solution. Usually the dilution factor at each step is constant, resulting in a geometric progression of the concentration in a logaritmic fashion. A ten-fold serial dilution could be 1 M, 0.1 M, 0.01 M, 0.001 M.
  3. A bit outdated but I came across an interesting article. Apparently, everything is our life and around can be managed by chaos. Is it possible then to assume that in chaos is order? Reigning in Chaos in Particle Colliders Yields Big Results From the Journal: Chaos By AIP News Staff WASHINGTON D.C., June 30, 2014 – When beams with trillions of particles go zipping around at near light speed, there’s bound to be some chaos. Limiting that chaos in particle colliders is crucial for the groundbreaking results such experiments are designed to deliver. In a special focus issue of the journal Chaos, from AIP Publishing, a physicist at the European Organization for Nuclear Research (CERN) details an important method of detecting and correcting unwanted chaotic behavior in particle colliders. The method is helping accelerator physicists design high-performing, cost-efficient accelerators in an era of constrained science budgets. The aim of the focus issue is to review, comprehensively, the theory and implementation of existing methods of chaos detection and predictability -- as well as to report recent applications of these techniques to different scientific fields. The Focus Issue: Chaos Detection Methods and Predictability is collection of 12 papers representing the wide range of applications, spanning mathematics, physics, astronomy, particle accelerator physics, meteorology and medical research. Chaos has long bedeviled physicists trying to describe the precise motions of interacting objects. The French mathematician Henri Poincaré discovered the essence of the phenomenon in the late 1800s when he attempted (unsuccessfully) to predict precisely the motions of the solar system’s planets. The same chaotic behavior appears in the crowds of particles traveling inside accelerators like CERN’s Large Hadron Collider. In these machines, powerful electric and magnetic fields accelerate and guide beams containing trillions of particles. Ideally all particles would travel in orderly orbits around the rings into which they are injected. But in reality, some of the particles spread out around the ring’s center, where they can become chaotic due to their mutual interactions and to defects in the magnetic fields that guide them. Particles that get kicked out of stable orbit can then crash into the collider’s ultra-cold superconducting magnets. If this happens too often, the magnets heat up and the particle beams have to stop, which compromises experiments and creates costly delays. From previous work in astronomy, Yannis Papaphilippou, a physicist at CERN, knew of a method called “frequency map analysis” that relates the frequencies at which objects oscillate to their chaotic behavior. Over the course of more than a decade, Papaphilippou and his colleagues applied the method to visualize those same frequencies in simulations of particle beams in accelerators. Using such simulations, physicists can design colliders to avoid chaotic beam interactions and keep particles on track.

  4. I hope it will help even a little bit: http://www.scienceclarified.com/A-Al/Acetylsalicylic-Acid.html http://en.wikipedia.org/wiki/Phenol http://www.britannica.com/EBchecked/topic/455507/phenol
  5. This is by far the best and the most reliable solution
  6. I am not sure any test can actually estimate our intelligence because there's so much more to it. I remember seeing so called IQ Tests which were basically all mathematical. I understand that mathematics is queen of all the sciences but really? LIke someone said, maybe IQ and intelligence are not so all together. There are so many cultural dependancies too which need to be taken under consideration.
  7. ABC Did you manage to "cure" the cells or at least identify what was wrong?
