Dissecting the Presence of Arachnophobia in Northern Kentucky Although Spiders provide a plethora of benefits to our community, they continue to be one of the most feared insects not only in the Northern Kentuckian area, but also throughout the world. In this project, I will hopefully come to a conclusion on why people generally fear spiders, which is an actual diagnosis called Arachnophobia. Spiders are in the arachnid class, which is the reason the condition is called Arachnophobia.…

INTRODUCTION Genetically modified organisms are a very controversial topic around the world. Primarily in the United States the debate is over whether they are safe as well as economically feasible to produce. There are many ways to look at this topic. First one must understand what a genetically modified organism is. After that, one must understand the advantages and disadvantages these organisms play. There are many advantages and disadvantages to genetically modified organisms. Some of the…

It is well known that fire fighters expose themselves to many hazards, from toxic gases, structural collapse, to fire and extreme heat. They don’t do it for glory but for the desire to help protect property and the people in their community. To help minimize risk to their health and safety, fire fighters use and carry protective equipment and wear specialized protective clothing, known as PPE. The Personal Protective Equipment (PPE) and the fire truck and equipment it carries has evolved…

Introduction Graphene is considered as pure carbon in the form of a very thin, one atom thick nearly transparent sheet. It is very strong for its low weight (100 times more stronger than steel and it conducts heat and electricity efficiently. While scientists had theorized about graphene for decades, it was first produced in the lab in 2003. Because it is virtually two-dimensional, it interacts oddly with light and with other materials. Researchers have identified the, ballistic transport of…

Question 2 What are stem cells (what characteristics define them)? Stem cells are cells that has the potential to develop into different cell types in the body during early life and growth. They serve as an internal repair system , dividing essentially without limit to replenish other cells as long as the person is alive .When a stem cell divides it can either remain as a stem cell or can develop into a cell with more specialized function like muscle cell, red blood cell etc. Two…

1.2. Cones Speaker cones vary in size and shape as well as the material they are made of. They range from original Rice and Kellog design-paper cone, through Kevlar and carbon fibre, metal (aluminium) and a variety of composites, each manufacturer employing different materials suited to providing the best efficiency and linearity. First of all they wanted to achieve manufacturing consistency since wood is not a homogenous substance and tends to vary from one form of timber to another, even…
