Migrasie

1. Die migrasie van persone na ‘n nuwe standplaas

  • Julle het reeds kennis gemaak met die migrasie van persone vanaf die platteland na die stad. Migrasie vind egter nie net plaas vanaf landelike na stedelike gebiede nie. Persone beweeg ook vanaf een stedelike gebied na ‘n ander, of selfs vanaf een land na ‘n ander.
  • Migrasie vanaf die plek waar jy jare gebly het, bv. Kaapstad na ‘n nuwe plek, bv. Londen, staan as EMIGRASIE bekend.
  • Migrasie na ‘n plek waar jy ‘n nuwe tuiste vind, staan as IMMIGRASIE bekend, bv. na Londen.
  • Migrasie is ‘n permanente verskuiwing na ‘n nuwe omgewing of standplaas.

R edes vir migrasie

Daar is verskillende redes waarom persone van woonplek verskuif. Hierdie faktore kan gewoonlik in twee kategorieë verdeel word, nl.:

  • Stootfaktore - faktore wat persone aanmoedig om ‘n gebied te verlaat.
  • Trekfaktore – faktore wat persoon lok om hulle in ‘n sekere omgewing te vestig.

Aktiwiteit 1:

Om inligting uit ‘n grafiese voorstelling af te lei

[lu 1.2]

Bestudeer die volgende prent en beantwoord die vrae wat daarop volg:

1. Watter proses word deur die illustrasie uitgebeeld?

2. Watter omstandighede in Suid-Afrika dink jy het die persone laat besluit om so ‘n stap te neem?

3. Watter invloed het die tendens op die ekonomie van Suid-Afrika indien hoogsgeskoolde werkers die laat in groot getalle sou verlaat?

2. Faktore wat migrasie bevorder

2.1 Stootfaktore

Stootfaktore speel ‘n belangrike rol as oorsaak van migrasie. Stootfaktore kan hoofsaaklik in drie kategorieë verdeel word:

a) Politieke faktore : politieke faktore is waar persone immigreer weens die druk of vervolging wat hulle ondervind in hul geboorteland. Gedurende die Apartheidsjare het verskeie swart Suid-Afrikaners die land verlaat en hulle elders gaan vestig, bv in Engeland en Europa. Dit was weens die politieke druk en vervolging wat hulle hier moes verduur, asook die gebrek aan geleenthede vir onderwys.

b) Ekonomiese faktore : ekonomiese faktore is waar ‘n ekonomiese stelsel van ‘n land nie voordelig is vir die persoon nie en hy na ‘n ander land trek om beter te kan leef. So het baie persone na die VSA en Engeland verhuis waar beter werksgeleenthede beskikbaar was.

c) Omgewingsfaktore : persone word ook weggedryf van die plek waar hulle woon weens ‘n ongunstige fisiese omgewing. Te veel of te min water mag ‘n ernstige bedreiging vir die omgewing inhou. Sommige persone is verplig om te trek, weens die feit dat hulle op die vloedvlakte van ‘n rivier woon. Tydens ‘n vloed word eiendomme en persone deur die watermassa bedreig.

Aktiwiteit 2:

Om persoonlike ervarings skriftelik oor te dra

[lu 1.5]

Op jou eie

Jy is ‘n trekarbeider wat help om die vrugte in die Boland te oes. Jy werk op ‘n plaas naby Worcester. Skryf ‘n brief aan jou familie wat in Kimberley woon, en beskryf aan hulle onder watter moeilike omstandighede jy moet woon en werk.

P olitieke stootfaktore

  • Dikwels is persone verplig om hulle land te verlaat weens vervolging of bedreiging van hulle lewens as gevolg van hulle politieke idees. Hierdie vlugtelinge moet dan elders ‘n heenkome soek. Hulle kan nie weer na die land terugkeer nie weens vrees vir hulle lewens.
  • Uit die vorige Oos-Europese lande moes baie mense vlug omdat hulle nie met die idees van die politieke party aan bewind saamgestem het nie.
  • In Zimbabwe vind ons ook dat baie mense tans na die buurstate, soos Suid-Afrika vlug. Aangesien hulle politieke idees verskil van die van die heersende party, word hulle deur sommige lede van die heersende party aangerand en gemartel. Dit dwing hulle om die land te verlaat.

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.

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?

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.
