This document discusses the concept of developing chewing gum that can generate energy through chemical reactions during chewing. The mechanical action of chewing would cause a chemical reaction in the gum molecules, transforming the mechanical energy into chemical energy. This chemically altered gum could then be used as a battery to power small electric devices, providing a clean, cheap, and portable source of energy available anywhere.
E-waste refers to electronic waste such as old computers and cell phones. It matters because it contains toxic chemicals like lead and mercury that can poison the environment if not disposed of properly. While some e-waste is recycled, much of it is illegally exported to developing countries that lack proper regulations, posing health risks, so laws around e-waste need to be strengthened to improve safe disposal and recycling.
This document discusses potential solutions to the problem of people being forced to give up their pets due to housing restrictions. It notes that landlords and homeowner associations often do not allow pets or limit the number allowed. The document then categorizes possible solutions as cultural/social, technological, legal, or virtual. Technological solutions proposed include soundproofing with egg cartons, scratch-resistant walls, pet shoes, and air fresheners. Virtual solutions involve virtual pet games or physical robot pets to replace natural pets.
Renal manifestations can occur in patients with rheumatoid arthritis due to the underlying disease, drugs used to treat it, or concurrent kidney diseases. The most common renal disorders associated with rheumatoid arthritis are membranous nephropathy, secondary amyloidosis, focal glomerulonephritis, rheumatoid vasculitis, and analgesic nephropathy. Rheumatoid vasculitis is a rare complication characterized by inflammation of small and medium blood vessels, commonly causing skin ulcers, nerve damage, and organ involvement. Diagnosis involves medical history, urine and blood tests, and sometimes kidney biopsies. Treatment depends on disease severity but may include high-dose steroids and immunosuppressive drugs.

3. HISTORIA DEL TELÈFON
La història de l'actual telèfon es remunta a 1854, quan
el francès Charles Bourseul va construir un aparell
que va anar el primer predecessor.
4. FUNCIONS DEL TELÈFON
El telèfon és un dispositiu de telecomunicacions que
s'usa per transmetre i rebre so a través de llargues
distàncies
5. COMPARACIONS DE TELÈFONS
Els movils antics: El primer telefon movil va ser el Motorola
DynaTAC 8000X i va aparèixer per primera vegada l'any de
1983. Un telefon movil molt senzill dissenyat unicament
per cridar.
els movils actuals han avançat molt, sobretot en les
funcions que pot realitzar un telefon movil des de la seva
funció fonamental, cridar, fins a poder usar-ho
practicamente com a ordinador. Els últims exemplars són
tàctils

7. EL MOVIL EN L’ACTUALITAT
En l'actualitat s'està vivint un procés de convergència en els
dispositius mòbils, que suposarien la suma d'un sistema
operatiu (smartphones) i de PDAs amb connexió sense fil
Segons dades de juliol de 2008 hi ha milers d'aplicacions
que permeten personalitzar el terminal. També és pot
disposar d'aplicacions web que facilitin l'accés i l'ús de
serveis que utilitzen la xarxa, com Facebook.
