Steel plate has become widely used in the construction and manufacturing industries, and projects cannot exist without it. What many people fail to realize is how not all steel plate has been created equal. In fact, a lot of steel plate grades have unique traits that will make them better for more specific applications. For example, structural steel grade A514 T-1 has been designed so that it has been heat treated. That means that you have higher strength capabilities, and it will weld better.…

A roofing job on a commercial building can represent a significant investment, but since few flat roofs will last more than 20 or 30 years, it is an expense that most commercial property owners will face eventually. Although the average cost for a typical flat roof on a commercial building is approximately $30,000, there are numerous factors that could drive that price up or down substantially. Here are some of the considerations that influence the cost of a commercial roofing job. Type of…

population recycles on a daily basis as more than 10% of Americans completely not involved in recycling practices (Ali). Therefore, there should be a priority to seek to bridge the existing knowledge gap. For instance, recycling involves reusing waste materials or products to produce a new product that is actually the knowledge Californians understand and yet, the environment around them is pathetically suffering from their irresponsible behaviors, such as waste disposals, deforestation, and…

Lead is a toxic metal that can enter the body by inhalation of lead dust or ingestion when touching the mouth with lead-contaminated hands. If leaked onto the ground, acid and lead particles contaminate the soil and become airborne when dry. Children and fetuses of pregnant women are most vulnerable to lead exposure because their bodies are developing. Excessive levels of lead can affect a child’s growth, cause brain damage, harm kidneys, impair hearing and induce behavioral problems. In adults,…

In Zhihua Hu's article, "Bottled Water... Quality," James Gleick states, "Eighty-five million bottles of water are consumed in the United States every day and more than thirty billion bottles a year." Many people do not realize what they are doing to the environment when they dispose of their water bottles. Individuals take advantage of the environment by using bottled water as a convenient resource. Bottled water has not always been available to individuals. While most people living in the…

How many of us recycle? Unfortunately, the answer is simple: not nearly enough. There plenty of excuses why you don’t recycle. “It doesn't make a difference,” “It’s too hard to do,” or maybe even “They don’t pay me to do it.” But, are any of these reasons honestly justification not to do it? Recycle has immediate and long-term effects on our planet, all of which are good—how many can say that about not recycling? You don’t have to be a hippie to care about the planet or even to recycle. So, I…

Small cracks, cavities, and notches in perfect material can dramatically reduce the tensile strength by producing stress concentration around them [ref]. We believe that in mammalian connective bone tissues, canaliculi, osteocyte lacunae, blood vessels and muscle insertions produce stress concentration to delay the progressive spread of minute cracks. Often times the cracks that are running against lacunae, for examples, stop on entering the lacunae, Hessian canals and blood vessels [ref]. We…

If we really want to save the environment then we should get rid of plastic water bottles! Why get rid of plastic water bottles? Well, because first of all, it is horrible for the environment, and because it is a big scam. We might as well buy electricity in a can for a lot more money.

When engaging in a dialogue about bottled water, it is vital to recognize both sides of the argument to generate progress and make concessions that identify its positive and negative effects. However, it is unquestionable that the negative effects of bottled water exceed its positive effects, because its negative effects on human health and the environment supersedes all the positive effects it has such as its convenience for consumers. With our planet being exploited of its resources and being…
