BRON E - Francois le Vaillant (1753 – 1784)

BRON F – Thunberg (1771– 1779)

Hy besoek Mosselbaai, Plettenbergbaai, Namakwaland, Damaraland, Betsjoeanaland en die Kalahari.

Hy besoek die volgende plekke: Bergrivier, Knysna, Gamtoosrivier, Saldanha, St. Helenabaai, Hexrivierberge, Swellendam, Kromrivier, Sondagsrivier

BRON G – Mungo Park (1805 – 1806)

Die mense is eerste gelok na Afrika deur die stad van rykdom, Timboektoe en om die oorsprong van die Nigerrivier te vind. In 1794 is Mungo Park (Skotland) gekies om dié twee geheime te gaan opklaar. Sy reis het goed begin, maar later is hy besteel en in ‘n tronk gegooi deur van die plaaslike regeerders. Hy het later wel daarin geslaag om te ontsnap en bereik tog die Nigerrivier. Sy ervaringe het hy opgeteken in sy boek: Travels in the Interior Districts of Africa . Sy tweede ekspedisie het in 1805 begin en het rampspoedig geëindig toe Park en sy manne verdrink het nadat hulle deur soldate aangeval is. Tot 1830 het mense probeer om die oorsprong van die Nigerrivier te vind, maar hulle was onsuksesvol.

BRON H – René Caillié (1827 – 1828)

‘n Fransman, René Caillié, het gereageer op die beloning van 10 000 frank. In April 1828 bereik hy Timboektoe om uit te vind dat die stad verarm het en dat die handelskaravane nie meer die plek besoek het nie. René het wel sy beloning ontvang.

BRON I – 1740–1838

Ses mense sterf in die soektog na die oorsprong van die Nigerrivier:

D. HughtonM. ParkF. HornemannJ. RitchieW. OudneyH. Clapperton

BRON J – BURTON, GRANT EN SPEKE

Vir miljoene mense was die Nylrivier in Egipte ‘n belangrike bron van lewe. Elke dag het die mense van die Nyl se water gebruik, maar die oorsprong het altyd ‘n groot geheim gebly. Reeds van vroeg af het die mense probeer om die oorsprong te vind, maar was onsuksesvol as gevolg van groot afstande, kwaai hitte en koors wat die mense oorval het. Ptolemaeus se kaart met die Maanberge het avontuursoekers geprikkel om na die oorsprong te gaan soek.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

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.
