According to the statistics of 2014, the population of Clallam County is estimated at 72,715 (Vleming). It is of particular importance for the economy and further development of the region to increase its population, not only in quantity but also in ethnic diversity. Relevant data demonstrates that the population of the county rose only to 1.8 percent (Vleming) during the four-year period whereas the populace on the county in general expanded to 5.0 percent (Vleming) over the same period. Speaking about the biggest city, Port Angeles, its rate of population growth reached only 1.1 percent after April 2010 ( ...

Lignin Chemistry

Lignin History Lignin is a plant-derived biopolymer with several applications. It is considered an effective alternative to chemically synthesized plastics that pose serious environmental problems during manufacture and disposal. Lignin is often obtained as a byproduct in paper and pulp manufacture. Lignin has to be dissolved to obtain cellulose from wood. In 1838, Anselme Payen discovered that wood contained cellulose, and oxidizable coatings (later called lignin) that bind the cellulose together (McCarthy and Islam, 2000). This coating material could be removed from wood after acid treatment and washing with an aqueous alkali solution (McCarthy and Islam, 2000). Later, several ...

Literature review

In the history of the construction of sea structures in oil exploration, load and corrosion together with how those structures will be maintained have always posed a scientific nightmare. Chamberlain, Adam and other authors in a scientific journal illustrate that for a good design of an onshore structure, there should be a right proportion of the ingredients in order for the structure to give maximum life service. They all agreed that in order to achieve this, keen interest should be paid to the permeability, strength, and durability of the mixture. Finally, they added that for effective control of corrosion, ...

0. Introduction Moto-cars are made from metals. This very common opinion was almost entirely true during almost all the previous century though opposite solitary examples (displayed at images below) are very well known for car likers: wooden bulks, a rubber car, a fiberglass sport car, a car with plastic bulk facias based on soybeans, a concept of a ceramic car, a glass car, and so on. All those examples are just very rare exceptions. Moreover, the probably refer rather to arts than to industry. However, in the current century, metals lost their monopoly. In the present essay, several material ...

Project Title:

Geotechnical and Structural Design for Composite Pile Description of the Problem: Composite piles are significant element of the structural design and stability of a number of constructions, including marine environments, bridges and more. As such their strength and durability is tantamount to both their longevity and the safety of the structures that they support. The following study will focus on geotechnical design as a means of increasing vertical and lateral load, through structural design, to improve the durability and weight bearing capacity of the design.

Methodology:

The methodology which will be used is a meta-analysis of existing studies. While it ...
