Module 11

Grondgebruik

Aktiwiteit 1

Om die verskillende gebiede in ‘n dorp/stad te identifiseer [lu 1.3, 2.1]

Julle het beslis al agtergekom dat julle dorp, voorstad of stad in verskillende dele verdeel is. Die deel waar die meeste winkels en kantore geleë is, word die sentrale sakekern genoem (met besighede/winkels en kantore). Dan is daar ook die nywerheidsgebied (fabrieke en werkswinkels) en die woongebiede (woonhuise en woonstelle). Daar is goeie redes vir dié verdeling. Dit sal mos nie lekker wees om reg langs ’n fabriek te woon waar daar die hele dag lank ’n geraas en ’n gewoel en ’n gewerskaf is nie!

Weet julle watter soorte geboue ons in elk van hierdie gebiede kry? Vul dit in die tabel in.

Sentrale sakekern Nywerheidsgebied Woongebied

Stadsbeplanners

Mense wat te doen het met die ontwerp van stede en dorpe, word stadsbeplanners genoem. Stadsbeplanners bepaal nie net waar woonbuurte, fabrieksterreine en die sentrale sakekern moet wees nie, maar sorg ook dat grond afgebaken word vir die aanlê van kerke, skole, ontspanningsgebiede, sportterreine, strate, parkeerterreine, en vir dienste soos spoorlyne, kragvoorsiening, telefoonverbindings, riolering, en dies meer. Julle kan verstaan dat stadsbeplanners sommer aan baie dinge aandag moet gee.

Op amptelike stadskaarte word grondgebruik in verskillende kleure aangedui. Deur na die kleure op te let, kan ’n mens vasstel of ’n deel vir bewoning, of fabrieke, of wat ook al, gebruik word.

Aktiwiteit 2

Om ‘n grondgebruikkaart te voltooi en te bestudeer [lu 1.1, 1.3]

Die onderstaande tabel sê watter kleure vir die verskillende gebiede op ‘n grondgebruikkaart gebruik word. Voltooi dit deur die sleutel korrek in te kleur. Daarna moet julle die grondgebruikkaart met die regte kleure inkleur.

1. Sakegebied (donkerblou)
2. Nywerheidsgebied (pers)
3. Hoëdigtheidsbewoning (oranje)
(nie genommer) Enkelbewoning (geel)
5. Sport en ontspanning (donkergroen)
6. Openbare oop ruimtes (liggroen)
7. Landbougrond (donkergroen omlyning)
8. Skole (grys)
9. Kerke (grys // 45 o swartarsering)

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
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.

what is the application of nanotechnology?
Stotaw
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
Prasenjit
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
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
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.
