Listing 6 . Adjust column and row counters.

if(++spriteCol == spriteColLim){ //Column limit has been hit, reset the// column counter and increment the // funSequenceCnt.spriteCol = 0; funSequenceCnt++;

Execute the pause sequence if it is time for it

The last statement in Listing 6 increments the funSequenceCnt . The first statement in Listing 7 tests to see if it has a value of 5. If so, all five cycles of the fun sequence have been executed and the code in the body ofthe if statement that begins at the top of Listing 7 will be executed. The purpose of this code is to execute two cycles of the pausesequence.

Listing 7 . Execute the pause sequence if it is time for it.

if((funSequenceCnt == 5) || (spriteRow == 1)){ spriteRow = 1;//advance to second row//Increment the pause sequence counter. pauseSequenceCnt++;//After two cycles in the pause mode, reset // variables and start the overall cycle// again. if(pauseSequenceCnt == 3){spriteRow = 0; funSequenceCnt = 0;pauseSequenceCnt = 0; }//end if on pauseSequenceCnt}//end if on funSequenceCnt }//end if on spriteColLim in

The conditional clause

The conditional clause in the if statement at the top of Listing 7 also tests to see if the row counter is pointing to row 1. If so, this means that the pause cycle has already begun and should be continued. Therefore,the body of that if statement will be executed. In other words, the body of the if statement will be executed if the funSequenceCnt is equal to 5 or the spriteRow is equal to 1.

Set the row counter to 1

The first statement in the body of the if statement sets the row counter to 1. This is necessary because control may have just entered thebody of the if statement for the first time following completion of five cycles using the sprites in row 0 (the top row in Figure 1 ).

Increment the pauseSequenceCnt

Then Listing 7 increments the pauseSequenceCnt and compares it with the literal value 3. If there is a match, two cycles of animation usingthe sprite images in the bottom row of Figure 1 have been completed and it's time to return to the five cycles using the sprite images in the top row of Figure 1 .

To accomplish this, the row counter, the funSequenceCnt , and the pauseSequenceCnt are all set to 0. This will cause five cycles using the sprite images in the top row of Figure 1 to be executed before control will once again enter the code in Listing 7 .

Adjust sprite position and frame rate

The code that we have examined so far mainly deals with selecting the sprite image to draw each time the Draw method is called. We haven't dealt with the location where the sprite will be drawn in the game window, theorientation of the sprite when it is drawn, and the frame animation rate of fast versus slow .

Listing 8 adjusts these drawing parameters.

Listing 8 . Adjust sprite position and frame rate.

if((spriteRow == 0) || ((spriteRow == 1)&&(spriteCol == 0))) { msPerFrame = fast;spritePosition.X += frameWidth * scale / slide; }else if ((spriteRow == 1) || ((spriteRow == 0)&&(spriteCol == 0))){ //Stop and display images.msPerFrame = slow; }//end if-else

Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
