Odnos prema društvenim mrežama
U savremenom svetu, društvene mreže postale su neizostavan deo svakodnevnog života. Bilo da je reč o tinejdžerima, odraslima ili čak starijima, gotovo svi imaju naloge na mrežama poput Instagrama, Tiktoka, Fejsbuka ili Tviteru. Društvene mreže omogućile su ljudima širom sveta da se povežu, razmenjuju informacije, misli i emocije, ali istovremeno su otvorile i mnoga pitanja o njihovom uticaju na naše ponašanje, osećanja i međuljudske odnose.
S jedne
...**Kad bolje sagledamo život oko sebe, shvatamo da nije tako lep i pravedan kao što nekad mislimo. Na površini, čini se da sve funkcioniše kako treba, ali ako zađemo dublje, videćemo mnogo nepravde, lažnih optužbi i nemoći običnog čoveka. Upravo to nam pokazuje Ivo Andrić u svom romanu Prokleta avlija. Čitajući ovo delo, sve više uviđam da i mi, na neki način, živimo u jednoj vrsti "proklete avlije", mestu gde je istina često nevažna, a nevini ispaštaju.** "Prokleta avlija"

In ground wave propagation, radio waves travel along the surface of the Earth, following the curvature of the planet. Freq Range: 30 kHz to 300 kHz (Low Freq). Key Points: Travels along the ground. Strongly attenuated by terrain, trees, buildings, etc. Limited to short distances (few hundred km). APPS: AM radio (MW band). Navigation systems & military communication.In sky wave propagation, radio waves R transmitted towards the ionosphere, which reflects or refracts them back to Earth. Freq Range:
Mesoamérica:
Zona geográfica y cultural que incluye parte de México y Centroamérica.
Características: agricultura (maíz), politeísmo, escritura jeroglífica, calendario.
Cosmovisión:
Relación entre dioses, naturaleza y humanos.
Ciclicidad del tiempo y sacrificios como ofrenda a los dioses.
Aportaciones de 3 culturas:
Olmeca: calendario, escritura, cabezas colosales.
Maya: sistema numérico con el cero, astronomía, arquitectura avanzada.
Teken f(x) = a^x of log_a(x)
Horizontale lijntest → inverteerbaar?
Inverse: y = a^x ⇔ x = logₐ(y)
Uit tabel of grafiek → herken exponentieel of logaritmisch
Zoek a via punt:
Exponentieel: f(x) = a^x
Logaritmisch: f(x) = logₐ(x) → a^y = x
Zelfde grondtal? → vergelijk exponenten
Anders: log aan beide zijden
Vergeet bestaansvoorwaarden (bv. log > 0) niet

Chemical vapour deposition, a hybrid method using chemicals in vapour phase is conventionally used to obtain coatings of a variety of inorganic or organic materials.It is widely used in industry because of relatively simple instrumentation, ease of processing, possibility of depositing different types of materials and economical viability.Under certain deposition conditions nanocrystalline films or single crystalline films are possible. There are many variants of CVD like Metallo Organic CVD (MOCVD)
