Hunting Proves both Profitable and Crucial

10

“Hunting is necessary to keep the deer herd at a healthy level,” Missouri Department Conservation wildlife biologist John Vogel tells SciJourner. “Without hunting, you could see a variety of effects ranging from a largely diseased deer herd to deer running all over the road and getting hit by vehicles.

Experts say that deer are a vital part of the ecosystem.

As Vogel explains, “If a deer herd becomes too vastly populated, the chance for spreading diseases increases dramatically.” Along with the increased deer herd that would come with no hunting, deer diseases would be more common. “The most prevalent diseases in Missouri are the Blue Tongue disease and the Chronic Wasting Disease, both of which are fatal,” comments Vogel. “The insects that spread those diseases would have more hosts to prey on.” 

“A good density of deer that would be able to withstand such a disease infestation would be about 25 deer per square acre,” Missouri Regional Wildlife Supervisor Joel Porath explains. “About 300,000 deer are killed annually by hunters in Missouri. If hunting was eliminated, you would have about 300,000 more deer crossing the roads, making the chances for [a car] hitting a deer go up dramatically.”
Deer hunting also represents a large amount of money that goes into the economy each year. As Vogel points out, “There is more than $1,000,000 that hunters spend in Missouri. That ranges in everything from equipment, to clothing, to gas, to food, and even lodging”.
“In the entire United States,” Porath adds, “the total amounts in the billions, and without it, many businesses wouldn’t see a rise in consumer spending from about the middle of October on.”

Another positive impact that hunting has on the economy is through Share the Harvest. It is a program through which hunters donate their kill to food pantries. The meat processors that participate in Share the Harvest are US Department of Agriculture inspected, insuring that the meat is properly handled. “In 2007, 320,000 pounds of venison were donated in Missouri alone,” John Vogel explains, “That is nearly 800,000 meals for needy families.”

“If hunting was banned, several events would occur,” says Vogel. “The population would be able to sustain itself for a while. The reproduction would increase, as would the population. Eventually the habitat would lose a large amount of underbrush due to the deer eating it all. The animals, which required that type of vegetation to live, would end up being very scarce. The forest would have a low diversity of vegetation due to only mature trees not being eaten. In the end a lack of food and the high possibility of an epidemic of diseases would be the demise of the deer herd.”

Stuck in the Truck?

What can the concrete truck driver do if he or she is hopelessly stuck in traffic with 20,000 pounds of material hardening in the twirling drum on the back? Add sugar. Really!

 

Very little new construction can take place without the use of concrete. It’s used all over the world. To find out how much is being used, experts track the key component of concrete, Portland cement. According to the latest statistics, nearly 2.9 billion tons of cement was produced in 2008, reports cemnet.com, publishers of the International Cement Review. Most of that cement was used in China; the United States ranked third worldwide, adds cemnet.com.   According to the Portland Cement Association, the United States used nearly 94 million metric tons worth of the stuff in 2008, worth $10 billion.

 

Portland cement is a careful blend of limestone and clay. The mixture is crushed to form a powder, which is then heated to about 1500ºC to convert the limestone to lime and melt the ingredients. After it cools, a lumpy gray material called clinker is left. Gypsum is then added and the clinker is ground into fine particles.

 

To make concrete, sand, coarse aggregate such as gravel, and water are added to the Portland cement. The ingredients are mixed, and a process called hydration turns the Portland cement into a rock-hard mass. Hydration means water is incorporated, so wet and cured concrete weigh about the same- the concrete doesn’t get lighter as it “dries”.

 

Other materials can be added to the Portland cement or to the final concrete mix to alter the engineering properties such as workability, strength, and curing time.

 

Sugar is a well-known and inexpensive concrete retarder . Concrete usually takes about two hours to begin to harden once it is mixed. Sugar is thought to interfere with hydration. About 10 pounds of sugar in a full load of concrete buys the driver an additional four hours. 

Meet the IPODERs

Are you an IPODER? IPODERs are Internet-savvy, phone-addicted, opportunistic, digitally conscience folks, says Dr. Benjamin Akande, Dean of Business and Technology at Webster University. Akande spoke about Ipoders at the St. Louis Science Center’s SciFest on October 10, 2009.

 

IPODERs are always on their cell phone, surfing the Internet or doing something with technology, he says. Akande estimates that there are 115 million IPODERs in the U.S.

 

IPODERs are also busy social networking—communicating and socializing with other people online through sites such as Facebook, Twitter and YouTube.

 

“What this technology means is that everybody is important, that they are no more superstars, that we all superstars…it awakes all of us,” say Akande.  “We are all important in our right and that’s what I like about it. And if you can use it properly; if you can write; if you can speak; if you can be articulate; you can be the President of the United States.” 

Let the Bats Sleep in their Cave!

Do you play football, soccer, or any other contact sport?  Do you pick your nose? According to John Morley, Professor of Gerontology at St. Louis University’s Medical School, some of these activities could seriously affect the brain.  Something as small as picking your nose, or even playing contact sports, can increase you risk of developing Alzheimer’s, Morley told participants at the St. Louis Science Center’s SciFest 2009 in October.

 

 

Research has shown that taking hard hits to the head—for example, heading a soccer ball or getting tackled in football—can cause major brain damage and or head trauma that can lead to many other side effects, says Morley.  Effects can include dizziness, headaches, confusion, amnesia, loss of consciousness, and the inability to perform to potential during the following school year, according to sportsinjurybulletin.com.  There is data emerging, indicating that men that play in the National Football League, are much more likely to Alzheimer’s and dementia, Morley told SciJourner.

 

 

 

Alzheimer’s disease is a fatal brain disease that 5.3 million Americans are living with today and the seventh-leading cause of death in the United States, according to the Alzheimer’s Association.  Alzheimer’s destroys brain cells, causing memory loss and problems with thinking and behavior server enough to affect work, lifelong hobbies or social life.  The disease gets worse over time, and is extremely fatal. 

 

 

 

 

 

Even stranger, according to Morley, “nose picking can lead to Alzheimer’s. Picking your nose can inflame the cribiform plate—a horizontal bone in the in the nose.  This platelike bone is closely connected to the olfactory bulb—the part of the brain that regulates your ability to smell.  According to Morley, inflammation in the nose, sets off a cascade of cytokines, which are proteins that interact with the immune system to assist with the body’s response to infection.  This, in turn, leads to increased amyloid-beta protein production, the causative agent in Alzheimer’s disease.  In other words, when picking your nose, you irritate certain parts of it and cause inflammation, which may indeed, cause the Alzheimer’s Disease. — Nathan Bolden

 

 

 

 

 

 

Texting while driving: the new drunk driving?

6

 

“I been driving for three years, and out of those three years I have never gotten one ticket for [driving while texting],” says Mickeal, age 17. “And I do it all the time.”

Mickeal is not alone. Teens regularly text messages and drive, and many think it is not all that dangerous, according to a survey by SciJourner of 51 youth, ages 16 to 21.  Out of the 51 surveyed on facebook.com, 45% thought it could become dangerous, However, 21% said it would be dangerous for someone who didn’t know what they were doing, while 29% felt that it was a more careless behavior than dangerous. (The last 5% did not respond to the question.)

  Missouri is one of 19 states that have outlawed driving while texting (DWT). According to the New York Times published July 27, 2009, collision risks for teens increase 23 times when they are texting.

  A 2007 survey by the Automobile Association of America’s (AAA) and Seventeen magazine of 1,000 teens that drive, ages 16-17, found that 28% admitted to DWT. A separate study of adults, found that they, too, have joined into this behavior, according to the AAA website. Experts say that if the rate of DWT decreased, the percentage of teen accidents will also decrease.

   Getting teens to change behavior could be quite a challenge. “ I have been doing it [DWT] so long I don’t even have to look at the keyboard anymore,” Admits Mickeal. ”When I first started texting and driving I thought: I could get hurt. But by now I know how to look up at the road when I need to. So, I don’t have a problem anymore. I don’t feel it’s unsafe on my end.”

 

Book Review: Here is the Tropical Rain Forest

Here is the Tropical Rain Forest

Author: Madeleine Dunphy

Illustrator: Michael Rothman

Publisher: Web of Life Children’s Books (2006)

ISBN: 10: 0786812125

Reading Level: 3-8 years old

 

     Do you ask question about animals? Do you want to know how an animal lives in the rain forest? If so, then I would recommend this book.

     This book is about the food chain; it describes the producer and all the way to the carnivore. It also describes how other animals compete by eating the same thing as other animals.

     What the book does really well is describe how animals get energy and how they are living things just like humans—animals need food to survive, too.

     The book should have also included the differences between a food chain and food webs. Some kids may not understand the difference.

     The pictures are ok, some of them should be a little bit lighter and maybe more descriptive. However, the back of the book has good pictures of the animals in the book and their names. 

 

 

 

Book Review: Looking for Miza

Looking For Miza

Authors:  Juliana Hatkoff, Isabella Hatkoff, Craig Hatkoff, and Paula Kahumbu

Illustrators: Juliana Hatkoff and Isabella Hatkoff 

Pages: 30

Publisher: Turtle Pond Publications LLC.

ISBN: 0-545-08540-3

Price: $16.99

Reading Level: Grades 1-3 (ages 6-9)

 

 This book is about a family of gorillas in the Virunga National Park in the Democratic Republic of Congo. Miza was a very curious gorilla that liked to explore. One day she decided to go and explore the forest, but she never came back. So, her mother came looking for her and sadly she got lost, too. Miza’s father, Kabirizi, being the leader of the largest family of mountain gorillas in Virunga Park had to take care of 31 gorillas, and make sure that they were safe. Nevertheless, Kabirizi went looking for Miza and Miza’s mother. For a couple of weeks later there was no sign of Miza or her mother, until one day Kabirizi saw Miza in a bush.

         I think that this book should be read to little kids, because they would enjoy learning about gorillas. But personally I think that 9 to 11 year olds would like this book if they picked it up off the shelf. Little kids in grades 1 to 3 would not understand the purpose of the book. They would just look at the pictures and say, “Oh look monkeys!” But if you actually sit down and slowly read the book to them, and try to explain the story to them, then they’ll start to understand it better.
