Anthropology is the study of humankind throughout history. There are currently four subfields of anthropology (1) cultural anthropology which is the study of human behavior and cultural patterns within a society (2) physical anthropology is the study of humans as biological specimen (3) linguistics refers to the study of human language and how it has evolved throughout history. This includes the grammar and syntax used, and the relationship between culture and language (4) archaeology is the study of materials such animal and human remains, artifacts, and plants. This paper will be looking at Archaeology. Archaeology looks at materials found ...

The periodic table of elements, by far, stands among the most notable discoveries in the history of chemistry. Nowadays, probably everyone who has ever heard about chemistry heard about the periodic table of elements. Its implications on the scientific world are so enormous that it has even leaked out to the general public and have become associated with the chemistry itself. This is not surprising considering the scientific strength of this instrument. Using the periodic table, many characteristic properties of the elements can be predicted and many phenomena can be explained. This discovery put so much scientific knowledge together, ...

Polymers cells are the next-generation class of photovoltaic since they promise realization of light weights, mechanically flexible, larger area devices. The room temperature solution processing can be used in fabricating these devices. High-efficiency conversion power of about 10% has recently been obtained in tandem polymer cells (Huo et al., 2015). In single-junction, it’s achievable through lowering the density state to a level lower than the electron acceptor and the conduction band of the semi-conductor. Photovoltage is electromotive force obtained by a photosensitive material due to inducing radiant energy; photovoltaic relates electric current produced at a junction of two ...
