Material extraction

The mining and extraction of copper has several impacts on the environment. The extraction of copper is done in several steps and process using different technologies and mechanisms. The copper element is extracted from its ore through heating the ore using carbon. This process releases carbon dioxide gas into the atmosphere. It is a well known fact that carbon dioxide gas is a greenhouse gas which result into global warming. The result of the extraction is copper full of impurities. The impure copper is then placed under further treatment to eliminate the presence of the impurities. In most cases, ...

It is an intersecting fact to not that to date the notion of dynamic networks refers to either one of two different concepts. First the pattern of Links, in a network topology evolves dynamically in time. Second the nodes can be individual dynamic systems coupled by static links [5, 6, 10, 22 24]. Adaptive networks are not new. Nearly all real world networks are to an extent adaptive and adaptive networks occurs in multiple disciplines today [12, 13, and 18]. What is new is that in recent years adaptive networks have become a focal point of extensive investigation using ...

My experience on LAN cable wiring was a challenging one. I had to make sure that the crimping tool is placed properly to expose the wires. I also had to make sure that my hands are not trembling, so that I can steadily place the wires correctly. LAN cable wiring is unlike electrical wiring, wherein you have to connect the wires in their proper places. I have to be careful when cutting very thin plastic wires. Otherwise, I would inadvertently cut the cable when I apply too much pressure. I made sure that I was careful in inserting the exposed ...

Nature or Nurture?

John Gray, an author, famously stated that men are from Mars and women are from Venus, this quote highlights the huge differences between men and women especially in how they communicate. Just what is communication? (Allen, 2004) defines communication as “to represent the dynamic nature of processes that humans use to produce, interpret, and share meaning.” The big question is why the differences? Some researchers say that it is due to their different biological and neurological makeup (nature) while others say that it is because of socialization (nurture). This paper seeks to support the nurture school of thought using ...
