  2. Mac OS X emulator for Windows 10 - Science Forums

    www.scienceforums.net/topic/112422-mac-os-x-emulator-for-windows-10

    Use Windows dxdiag to check what CPU is installed physically, and use MacOS X equivalent for the same, compare whether VirtualBox is not detected wrong CPU.. If you will use code which is not checking whether CPU has some feature from more modern CPUs, it'll cause instant crash (e.g. trying to run SSE2 code on Pentium 1 will cause instant crash).

  3. Microkernel vs Macrokernel - Computer Science - Science Forums

    www.scienceforums.net/topic/19935-microkernel-vs-macrokernel

    Genius. Posted July 1, 2006. The most successful operating systems out there (NT, OS X, Linux) have all started from microkernel concepts and used them to build a macrokernel. While Linux merely borrows conceptually from a microkernel OS (Minix), NT and OS X are both derived directly from microkernel operating systems, and have since been ...

  4. Open vs Closed system - Computer Science - Science Forums

    www.scienceforums.net/topic/16421-open-vs-closed-system

    I personally think that closed system would be best as there would be no compatibility issues and since the OS footprint is so small as compared to a PC so all resources can be dedicated to the application ie game. And due to the nature of a closed system, better looking game (graphics, textures, AA, effects) can be made as compared to games on ...

    10. 11. Posted February 18, 2008. An array of N 1D simple harmonic oscillators is set up with an average energy per oscillator of (m + 1)hf Show that the entropy per oscillator is given by. S/N = k [ (1+m)ln (1+m) - (m)ln (m)] Comment on the value of the entropy when m = 0.

  6. Air as an insulator - Physics - Science Forums

    www.scienceforums.net/topic/43881-air-as-an-insulator

    Posted December 24, 2009. DJBruce said: Since electricity is just a flow of electrons any compound or element with tightly held electrons will act as an insulator as the element will impede the flow of electrons. For example polytetrafluoroethylene is an good insulator because the Fluorine holds its electrons so well.

  7. Closest to Absolute Zero - Quantum Theory - Science Forums

    www.scienceforums.net/topic/14749-closest-to-absolute-zero

    I've been searching around for the closest anyone's gotten to absolute zero... I can't find it now (forget what I searched for lol) but there was one dated 2003 that said 500 picoKelvins...

  8. What's the difference between ligands and cofactors?

    www.scienceforums.net/topic/62767-whats-the-difference-between-ligands-and...

    The ligand is an umbrella term for non-covalently bound compounds to enzymes. Based on that, where would you see the difference between those two?

  9. Radiacode: pocket-sized radiation detectors. Is it worth it?

    www.scienceforums.net/topic/134480-radiacode-pocket-sized-radiation-detectors...

    Also, the RadiaCode is sensitive enough to report where the plane changed its altitude - you can see a few small steps in the long flight, on top of a more smooth variation that is mostly due to the night-time effect (we get slightly more radiation from one direction in the sky than from the other). Radiation is strongly dependent on altitude ...

    www.scienceforums.net/topic/49453-what-are-the-effects-of-zinc-sulfate-nacl...

    Hi I wish to isolate eggs from sheep faeces and subsequently extract DNA and run a PCR from them. Part of the egg isolation technique involves floating them on a dense liquid. The three commonly used floatation liquids are Zinc sulfate, saturated sugar and saturated salt solutions. I was wonderin...

  11. Unheard of Formula - Inorganic Chemistry - Science Forums

    www.scienceforums.net/topic/15680-unheard-of-formula

    yes you can indeed replace the Na with H. it's all related to conjugate acidity/basicity: the reason H2SO4+MX-->HX+MSO4 (where m=metal cation and x=anion) is because HSO4- is a really weak conjugate base and metals tend to be really weak conjugate acids. consider: H2SO4+CsF-->HF+CsHSO4.
