Handel en Nywerheid

  • Die ekonomie en die omgewing is onlosmaaklik verweef. ‘n Gesonde omgewing is nie net van ekologiese belang nie, maar ook onontbeerlik vir die ekonomiese welsyn van die land. ‘n Gesonde ekonomie kan nie op ‘n geskende omgewing en afgetakelde natuurbronne gebou word nie.
  • Ekonomiese ontwikkeling wat nie die omgewing in ag neem nie, is nog aanvaarbaar, nog prakties. Dit is nie toevallig dat leidende maatskappye besef dat omgewingskwessies onlosmaaklik gekoppel is aan politieke, ekonomiese en maatskaplike kwessies nie. Hulle aanvaar dat die versorging van die omgewing ‘n maatskaplike verantwoordelikheid is, en het ook reeds besef dat bewaring voordelig vir sake kan wees en dat vandag se eko-verantwoordelikheid môre se wins is. Dit behels veel meer as die blote verbetering van openbare betrekkinge: hulpbron-doeltreffende tegnologie, beter energiebenutting, die vermindering van afval en die voorkoming van besoedeling, kan winste aansienlik opstoot.
  • Dit is algemeen bekend dat ‘n groeiende ekonomie die welvaart moet skep om alle Suid-Afrikaners se lewenspeil te verhoog en uiters noodsaaklike maatskaplike opheffingsprogramme te finansier. Hierdie ekonomiese ontwikkeling moet egter verskil van die patroon wat voorheen in Suid-Afrika en ander geïndustrialiseerde Westerse lande gevolg is en die omgewing geskend en ‘n geweldige maatskaplike tol geëis het. Dié proses moet volhoubaar wees en binne die drakrag van die natuurlike omgewing geskied – nie daarbuite nie. Die klem moenie net val op die aantal goedere en dienste wat gelewer word nie, maar ook op die groei van persoonlike en menslike hulpbronne.

Mynbou

  • Suid-Afrika is buitengewoon mineraalryk. Die land beskik oor die grootste bekende neerslae goud, chroom, mangaan, vanadium, andalusiet en die platinum-groep metale, asook reuse-reserwes ander waardevolle metale en minerale soos steenkool, nikkel, silwer, lood, fosfaat, uraan, titaan en sirkoon.
  • Die land kon sy vroeëre ekonomiese groei grootliks gehandhaaf deur die ontginning van hierdie nie-hernubare bronne. Mynbou het in 1961 sowat 29 persent van die Bruto Binnelandse produksie gelewer.
  • Mynbou is egter in wese ‘n nie-hernubare bedryf en kan nie ontwikkeling onbepaald na ‘n meer volhoubare ekonomie wat gegrond is op hernubare hulpbronne.
  • Mynboubedrywighede, wat oor sowat 1 persent van Suid-Afrika se oppervlakte voorkom, het massiewe omgewingskade aangerig en besoedeling in baie dele van die land veroorsaak.
  • Skade is byvoorbeeld aangerig deur die vrystelling van besoedelde water, lugbesoedeling (van brandende steenkoollae), afvalprodukte, osoonvernietigende CFK’s uit verkoelingsaanlegte en ruimteverkwistende mynhope en omgewingskending deur ongerehabiliteerde oopgroefmyne.
  • Daarbenewens is skaars hulpbronne, veral water en grond, in die verlede deur mynboubedrywighede verkwis en was mynbou ook die oorsaak van die ernstige omgewingsverwante gesondheidsprobleme onder sy werkers. Minerale ertsverryking het ook aansienlike omgewingskade aangerig.

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
hmm
Abhi
is it a question of log
Abhi
🤔.

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