Why some tablets are dispersible?

Fast dispersible tablets disintegrate either rapidly in water, to form a stabilized suspension, or disperse instantaneously in the mouth to be swallowed without the aid of water. A direct compression method was used to prepare these two types of tablets containing coated ibuprofen as a high dosed model drug. The properties of the water dispersible tablet, such as porosity, hardness, disintegration time and increase in viscosity after dispersion, were investigated. The selected tablet formulation, containing 26% galactomannan and 5% crospovidone, disintegrates before the galactomannan starts to swell. These tablets disperse in water within 40 s and show a crushing strength of 95 N. To develop an orodispersible tablet, a rotatable central composite design was applied to predict the effects of the quantitative factors mannitol and crospovidone as well as compression force on the characteristics of the tablet. Special emphasis was paid to the development of a wetting test, replacing the normal disintegration method. An optimum tablet formulation, containing 34% mannitol and 13% crospovidone, provides a short wetting time of 17 s and a sufficient crushing strength of 40 N. In conclusion, fast dispersible tablets with acceptable hardness and desirable taste could be prepared within the optimum region.

What you used with the CPU heat sink or fan and what is the difference between them?

Heatsinks and fans are used on CPUs to help cool them down so that they are not destroyed. A heatsink is a piece of metal placed on the CPU to distribute heat away from the CPU itself.

How do you record audio from computer not from the mic but from the speakers but record from a video for example?

as i understand you question u want to record audio in you computer without mic. you can use stereo mix option

List some of the reasons why you would replace old peripherals?

Interesting Question,

The obvious reasons are as the computer industries continues forward so does the need for faster cpus. High 3D in Games require more CPU power, The Next version in Windows requires a newer CPU and a larger Hard drive. If you are doing any work with video which is very common for the regular person to purchase a flip cam (or other type) you can then take your videos then download then upload then to you computer edit them and then move them to youtube; 10 years ago could not be performed without alot of effort.

Consider that when Windows 95 was released the system was

  • Personal computer with a 386DX or higher processor (486 recommended)
  • 4 megabytes (MB) of memory (8 MB recommended)
  • Typical hard disk space required to upgrade to Windows 95: 35-40 MB The actual requirement varies depending on the features you choose to install.
  • Typical hard disk space required to install Windows 95 on a clean system: 50-55 MB The actual requirement varies depending on the features you choose to install.
  • One 3.5-inch high-density floppy disk drive
  • VGA or higher resolution (256-color SVGA recommended)

Today for Windows 7 the requirements are:

  • 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor

  • 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)

  • 16 GB available hard disk space (32-bit) or 20 GB (64-bit)

  • DirectX 9 graphics device with WDDM 1.0 or higher driver

Additional requirements to use certain features:
  • Internet access (fees may apply)

  • Depending on resolution, video playback may require additional memory and advanced graphics hardware

  • For some Windows Media Center functionality a TV tuner and additional hardware may be required

  • Windows Touch and Tablet PCs require specific hardware

  • HomeGroup requires a network and PCs running Windows 7

  • DVD/CD authoring requires a compatible optical drive

  • BitLocker requires Trusted Platform Module (TPM) 1.2

  • BitLocker To Go requires a USB flash drive

  • Windows XP Mode requires an additional 1 GB of RAM, an additional 15 GB of available hard disk space, and a processor capable of hardware virtualization with Intel VT or AMD-V turned on

  • Music and sound require audio output

It is possible to run a system that was purchased 5 years ago, but not with the latest greatest software out there. Various Flavors for windows may work but with a need to upgrade for the memory or the hard drive to be upgraded as a minumum; and to say that least if you do get the system to work (ie. Vista) it will then be pretty slow. Other system can be installed like Linux / Ubuntu / and the like and run pretty well but that is for another discussion.

A friend has asked for help the computer hangs at odd times and sometimes gives insufficient memory errors the windows xp system has 512 mb ramone of the dimm modules might be going bad?

It's certainly possible - the easiest way to check - is to get hold of some spare memory modules - and install them in place of the ones they already have in their machine. If the computer runs perfectly with the replacement module - then you have your solution.

What is birnary code and why was it chosen to represent data computers?

Binary code are represented as 1s and 0s can look like 00000000 or 11111111 or 11001010 or any other combination thereof. The reason why it is chosen is its simplicity, the computer reads it as either one thing (a 1) or the other (a 0).

Any digital computer is just an array of switches and they can only have 2 states; on or off, 1 or 0. The switches can be arranged to have meaning in several number systems e.g. octal, Hexadecimal (hex for short) but the switches don't change, still they can either be on or off.

Can people be viewed by someone outside your home through computer monitor?

Some monitors contain a built in webcam. If your monitor includes a webcam they may be able to see you on that webcam unless you turn it off. If there is no webcam built in to the monitor they cannot see you unless you add a webcam to your computer. If you do not know if the monitor came with a camera, you can usually tell if there is a webcam as there would be a very small hole, about the size of a pin hole, in the top center of the trim around the screen. Sometimes there are 2 or 3 of these pinholes if the monitor has a mono or stereo microphone in addition to the camera. A lot of desktop monitors and most laptop computers include webcams now which can be turned on automatically when using programs like "Go To Meeting" and "Skype". If this feature bothers you, a piece of electrical tape over the hole will prevent anyone from seeing you. When you went them to see you remove the tape!

Why is escalation an important tool in computer troubleshooting?

"Escalation", in the world of computer troubleshooting is necessary when the current computer tech cannot resolve the troubling issue at hand. Escalation is an important tool because it allows one tech to involve a more knowledgeable tech so that one, or a number of problematic issues may be resolved. Simply put, without escalation, many problems would not be resolved for the end user.

What should one do when a USB does not show up when plugged into a windows vista laptop?

This happens to me what i do is unplug it then restart the computer and try it again and repeat 3 times if it continues to not work you may need to buy a new usb :( or you could contact a profensional its up to you.

You may also want to try plugging the device into another computer. If it works there, then the problem lies either with the USB port on the laptop, or the device may not be compatible with Windows 7

i hope this helped
