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.

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

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
Azam
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
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.
Ali Reply
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
