Scholars,
As we move through the protocol for scientific method this week, we realize how important it is to study other scientific research before conducting our own. For this weeks online assignment I would like you to find a biological article (periodical) (of your choice of topic) online, make sure the link to the article is in your post and discuss/sumarize the research you found.
(ABSTRACTS ARE OK but full text is preferred)
Here is a hint: go to google, at the top of the page click more... then click scholar then all you have to do is type in the topic of your choice.

I chose to research the mechanics of feline locomotion. The corresponding article i found is a study on the amount energy that is transfered through the kee and ankle of a cat as it moves forward. I chose this because im interested in how the mechanics work of biological beings in their everyday movements. I would be interested in learning how to make a mechanized version that walks in a similar fashion. I could only get ahold of the abstract because the full text costs. the abstract is below:
The purposes of this study were (1) to define and estimate the direction and amount of the energy transfer between the knee and ankle through gastrocnemius (GA) and plantaris (PL) muscles during cat locomotion, and (2) to test the assumption that the force and activity patterns of soleus (SO), GA, and PL are mechanically and physiologically advantageous for providing the transfer of energy between these joints. The direction, amount and rate of the energy transfer through a two-joint muscle were defined using a theoretical analysis of movements in two adjacent joints spanned by the two-joint muscle. The energy transferred between the ankle and the knee was calculated using the time integration of the difference between the power developed by the moments of SO, GA, and PL at the ankle joint and the total power of these muscles. The total power of SO, GA, and PL muscles, and the power of their movements about the ankle and knee, were obtained using the experimentally determined muscle forces, the rates of change in muscle length, and the angular velocities at the knee and ankle which were calculated from the kinematics and the geometry of the cat hindlimb. Muscular forces and hindlimb kinematics of the cats were recorded during normal walking and trotting on a treadmill at speeds of 0.4, 0.8, 1.2, 1.5, and 1.8 m s−1 using ‘E’-shaped tendon transducers and high-speed video, respectively. It was found that during the early phase of support, there was a transfer of mechanical energy from the ankle to the knee through GA and PL. During the late phase of support, mechanical energy was transferred from the knee to the ankle. The amount of energy transferred increased with increasing speeds of locomotion. The energy transferred from the ankle to the knee was 3–60 mJ (7–22% of the negative work done by the moments of SO, GA, and PL at the ankle), and the energy transferred from the knee to the ankle was 10–67 mJ (7–14% of the positive work done by the moments of SO, GA, and PL at the ankle). The results of this study suggest that the activation and the forces of one-joint SO and multi-joint GA and PL are organized in such a way as to fit the features of the design of these ankle extensor muscles in order to provide locomotion efficiently. For example, the decrease in the contractile abilities of SO during the late phase of support at fast speeds of locomotion may be compensated for by the transfer of energy from the knee to the ankle through GA and PL. The design of GA and PL (a high percentage of fast-twitch muscle fibers, large angles of pinnation and short length of the fibers, long tendons, and the location about the ankle and knee joints) seems to be well suited for transferring mechanical energy between the ankle and knee at fast speeds of locomotion. Because of the design of GA and PL, their contractile abilities remain close to the maximum at fast speeds of locomotion. The design of GA and PL allows for extension of the ankle joint through the action of the knee extensor muscles during knee extension with a relatively small change in length of GA and PL

I choose to research wind farms because I have heard about how they have been killing thousands of birds and bats, as well as disturbing all local wildlife and not being as efficeint as you would think they are. Below is an absract of the farms
Abstract
Wind farms (i.e. local assemblies of wind turbines) for power generation can only provide negligible useful
electricity to grid supply systems. Because they provide intermittent only power, they merely displace
thermal power stations onto standby mode while the thermal power stations wait for the wind to change.
Wind farms make no significant reduction to pollution because thermal power stations continue using their
fuel and producing their emissions while operating in standby mode. The large scale use of wind farms
requires upgrading of an electricity grid, more complex grid management, and operation of additional
thermal power stations to protect against power cuts in time of supply failure. These effects increase the
cost of electricity supplied by the grid in addition to the capital, maintenance and operating costs of the
wind farms themselves. Also, wind farms cause significant environmental damage. These severe
environmental costs may be worth suffering if wind farms actually provided cheap, clean, useful electricity.
They do not.

I chose to do research on hydrogen fuel that people say we could use for cars in the future which could save us from enviromental dangers. I chose this topic because automobiles and different fuels we could use to power them are both interesting.
Increasingly stringent legislation controls emissions from internal combustion engines to the point where alternative power sources for vehicles are necessary. The hydrogen fuel cell is one promising option, but the nature of the gas is such that the conversion of other fuels to hydrogen on board the vehicle is necessary.
Abstract:
The conversion of methanol, methane, propane, and octane to hydrogen is reviewed. A combination of oxidation and steam reforming (indirect partial oxidation) or direct partial oxidation are the most promising processes. Indirect partial oxidation involves combustion of part of the fuel to produce sufficient heat to drive the endothermic steam reforming reaction. Direct partial oxidation is favored only at high temperatures and short residence times but is highly selective. However, indirect partial oxidation is shown to be the preferred process for all fuels.
The product gases can be taken through a water-gas shift reactor, but still retain ∼2% carbon monoxide, which poisons fuel-cell catalysts. Selective oxidation is the preferred route to removal of residual carbon monoxide. Low-temperature oxidation in the absence and presence of an excess of hydrogen is reviewed. Au-based catalysts show much promise, but precious metal catalysts such as Pt/zeolite have some advantages.

I chose to research mine Electric vehicles and the urban environment. They say cars have become the dominant source of atmospheric pollution.
Absract: Due to the increased traffic volume, especially in urban areas, cars have become the dominant source of atmospheric pollution. Actions taken to limit the pollution have not been able to counteract the polluting effect of this increase in cars. Limited petroleum resources have initiated the search for alternative fuels for vehicles. These alternatives, except for hydrogen and electricity, will however only give a limited decrease of pollution and for some components, such as aldehydes, the pollution will increase.
Electric vehicles are attractive from both energy and environmental points of view and substantial development programmes are devoted to high energy density batteries which are expected to increase the range and market for this alternative.
The scope of this paper is to compare the overall atmospheric pollution for electric vehicles with the corresponding figures for internal combustion engined (ICE) vehicles using either gasoline or such alternatives as methanol and liquid petroleum gas.
It is shown that the total atmospheric emission for electric vehicles, including what is produced from the power plant, would on a per mile basis be 20% of the comparative figure for an ICE vehicle meeting Californian legislation, which is among the most stringent in the world. For ground emission, which is the most important parameter regarding influence on man and environment the corresponding figure will be substantially lower. Also, the noise level for electric vehicles is radically lower than for cars with internal combustion engines. Heres the link:

Im using this article because it was interesting and i dont think anyone else will take it. i honestly didnt truly understand the first time i read it so i thought it must be pretty good.
Within the field of biological control, there is a strategy that involves the attempt to control a native pest species with an exotic biological control agent. This strategy has been termed neoclassical biological control, and its ecological foundation differs markedly from other forms of biological control. Neoclassical biological control with a parasitic wasp and an entomophagous fungus from Australia is now being applied to rangeland grasshoppers in the western United States. Available evidence suggests that the costs of such a strategy greatly exceed the benefits. Although the probability of successful establishment may be low, if such an agent is established there are a number of possible nontarget impacts. Adverse effects include competitive suppression or extinction of both native biological control agents and nontarget acridids,as well as three forms of salamanders. which comprise the vast majority of extant grasshopper species. Suppression of nontarget acridids may result in loss of biological diversity, existing control of weed species, release of otherwise innocuous acridid species from competitive regulation, disruption of plant community structure, suppression of essential organisms vectored by grasshoppers, and disruption of food chains and other nutrient cycling processes. These impacts are particularly serious given that an established exotic agent is essentially permanent and spatially unbounded. Given that the value of the rangeland resource depends upon the largely unknown ecological processes that underlie its sustainable productivity, there are a number of management techniques that offer a greater probability of success with a markedly lower likelihood of ecological and economic disruption than does neoclassical biological control.

Global warming is such a large issue with many aspects that make it possible. I was interested though how the warming rate from the green house gasses make it possible for the catestrophic event to take place. Pollution adds to the gasses making a bigger effect, but it's just the the pollution. As said in the abstract many people think it's just from non-co2 gasses but it is from many others. It can change peoples minds on this situation, and hopefully make people realize what is happening to the planet.
Abstract:
A common view is that the current global warming rate will continue or accelerate. But we argue that rapid warming in recent decades has been driven mainly by non-CO2 greenhouse gases (GHGs), such as chlorofluorocarbons, CH4, and N2O, not by the products of fossil fuel burning, CO2 and aerosols, the positive and negative climate forcings of which are partially offsetting. The growth rate of non-CO2 GHGs has declined in the past decade. If sources of CH4 and O3 precursors were reduced in the future, the change in climate forcing by non-CO2 GHGs in the next 50 years could be near zero. Combined with a reduction of black carbon emissions and plausible success in slowing CO2 emissions, this reduction of non-CO2 GHGs could lead to a decline in the rate of global warming, reducing the danger of dramatic climate change. Such a focus on air pollution has practical benefits that unite the interests of developed and developing countries. However, assessment of ongoing and future climate change requires composition-specific long-term global monitoring of aerosol properties.

The topic of my article was the use of anabolic steroids in high school students and the drastic effects it can have on their bodies. Steroids are man-made substances similar to the male hormone testosterone. However testerone is naturally found in the body, wheras steroids are illegal except when issued by a doctor.
Even though steroids are drugs they are very difficult to purchase. Street names for steroids are roids or juice. These drugs can be taken in many different ways. The most common are in pill form or hypodermic needles injected directly into the skin.
However most teens are smart and stay away from steroids. A 2002 study shows that only 11% of 8th, 10th, and 12th graders have tried steroids.
The other 89% were wise enough to stay away from the infamous drugs as they cause many side effects such as pimples, males growing breasts (gynecomatastia), and girls growing beards (gynecomatastia).Angry violent rampages known as "roid rage" can also occur.
Reading this article convinced me that if you want to gain muscle do it the naturual way by lifiting weights and improving diet, not taking this dangerous shortcut which can drastically ruin someone's life.

Air pollution has been a major issue worldwide over the years. There was a deadly outbreak in the past In London of 1952, In Meuse valley of 1930, and in Pennslyvania of 1948. In the 60s to the 80s there has been less air pollution, but the effects are still costly. Many people have died from pneumonia, a stroke, and heart disease due to air pollution. Air pollution still renders a major issue today.

I chose to research the benefits of Aromatherapy. I’m interested in seeing how the sense of smell affects how we feel and what we do.
Aromas are sensed and analyzed in the reticular system of the brain stem. In this system, emotions, memories, and attention are connected. This is where aromatherapy is beneficial- it not only heals physical imbalances it affects emotions and memory as well.
Certain aromas can stimulate the hypothalamus, the part of the brain that controls the endocrine system and many body functions. The hypothalamus may then activate the pituitary gland, which produces hormones that can affect both the physical body and the emotions. Hormones influence emotions and behavior as well as regulate the activities of organs or specific groups of cells in the body. There is also evidence of a link between scent and immune system function.
Aromatherapy can be used to help depression, acne, sinus congestion, stress and anxiety, memory and learning, health and wellness, sleep, appetite, and emotions. It can help you to recall little simple things like birthdays, or where you left your keys, to deeper level things like recalling special memories.

My article studied testicular germ cell cancer. Basically, it gave a brief explanation on how they treated people for late relapse and now are disease-free. But some were treated by chemotherapy before the last relapse. They conclude that being treated with chemotherapy only/alone, is not as curable as surgery. Also, previously testicular cancer patients, should have annual- follow up evaluations.

I chose to research multiple personality disorder (a.k.a. dissociative identity disorder) because for some reason I am very intrigued by it.
Most people with MPD are diagnosed within the ages of 20-40. The hosts of this disease are often depressed and anxious, and have hyper active mood swings. The mood swings can result in the switch in personalities, and in some cases the host may have manic depression. The hosts don't really hear what we hear. Often their hearing is affected with hauditory hallucinations, sometimes in cases of schizophrenia. The most common treatment is for psychotherapy at least twice a week. Trust is an important factor with the host, and its alters (other personalities), and the therapist. Communication is equally important, hypnosis is an option for communication. It is very important that the therapist to get the host to accept the factor that caused his/her MPD. Sometimes the hosts will be hospitalized and given tranquilizers. The hosts are usually diagnosed with depression or anxiety over MPD. The treatment for MPD usually lasts at least 4 years.

I have chosen to perform my research the topic of natural selection. I chose this topic because I am interested in genetics, specifically heredity and evolution. The link included is a link to "The Origin of Species by Means of Natural Selection", written by Charles Darwin himself.
Natural selection can be described as the process by which favorable traits become more dominant in successive generations of a species, while unfavorable traits become less common. This pattern is due to an increase or decrease (respectively) in the frequency of a specific genotype. Organisms with a favorable phenotype, or observable characteristic, will be better suited to survive in their environment. Since more of these organisms survive, there will be more organisms with favorable traits mating. Over a period of many generations, certain unfavorable traits can be almost completely removed from a species. The favorable traits will be passed on, and these species can sometimes develop special adaptations needed to help survive in new or changing environments.

I chose to research about the human body. The study was designed to examine the effect of exposure to muscular ideal bodies on body satisfaction in men. Results said that mens self-rated body satisfaction decreased after viewing images of muscular men but did not change after viewing images of average men.
Abstract The current study was designed to examine the effect of exposure to muscular ideal bodies on body satisfaction in men. College men (N= 104) at a medium-sized mid-south university completed the Body Assessment (BA)scale, which measures body satisfaction, before and after exposure to either muscular or nonmuscular advertisements. BA scores were examined using a repeated measures (pre and post) ANOVA with muscularity of image (view images of muscular men vs. view images ofaverage men) as the between-participants factor. Results indicated that mens self-rated body satisfaction decreased after viewing images of muscular men but did not change after viewing images of average men. Thus, it appears that mens body satisfaction may be influenced by exposure to brief images of muscular models. These results are congruent with results of previous investigations of the effects of viewing images of thin models on womens body satisfaction.

I decided to take a look at fuel cell engines.
These machines are basically an alternative to our combustable engines today. The observation was that if you can take water or H2O and send an electrical current through the water to break it into the two elements that make up water, Hydrogen and Oxygen. This process is known as electrolysis.
Sir William Grove made the first fuel cell in 1839, his theory was that if you reverse the procedure of electrolysis by connecting hydrogen and 2 oxygen atoms you make water and electricity allowing two common elements to make a powerful energy source.
Now this procedure has many different ways of being acted and some best suited for different tasks, like the PEMFC is mainly going to be used for cars due for its low operating temperature of 60 to 80 Degrees Celsius and amount of electricity. Then there's the SOFC which is mainly a power plant because of its high temperatures of 700 to 1,000 degrees Celsius. As you can tell these fuel cells are going to be a major part of society in the future.

I chose to do my research on carbon monoxide poisoning because I have found it hard to understand how so many people in the world die from it, but to the human body it’s a very careless mistake. Carbon monoxide is the leading cause of all poisonings in the United States. When I think about carbon monoxide, I think of cars, cigarettes and how some people even use it as a suicide attempt. People have even died due to starting their cars in closed garages. Wouldn’t that be a sad way to die if you were in a car with someone on your way to school and then your life just end's because of the deadly fumes that have been filling your lungs. Cigarette packs even have labels on them to give a warning to the concealer that the cigarette smoke contains carbon monoxide. To me that’s not enough for those who have suffered due to their own or others careless mistakes. Even though carbon monoxide is a poison, it gives no warning sign to victims. Even doctors have patients who have complaints of headaches, being dizzy and even feeling slightly nauseous but they are misdiagnosed and never know that they have low levels of carbon monoxide poisoning. So to all who have ever felt this, learn to be cautious because carbon monoxide is a serious matter and not needed to be seen lightly.

I chose to do research on something that is becoming a concern to many people across the country: the effects of energy drinks on people.
The function of an energy drink is to provide energy to wake up the body. Many automobile crashes are a result of people falling asleep at the wheel. An experiment was tested where 12 young adults who drive a car after consuming an energy drink that contained glucose, surcose, 80-Mg of caffeine, taurine, and other key ingredients found in energy drinks. The test was supported as all the energy drinks made the young adults more aware and awake.
The main concern about energy drinks are how high they can increase one's heartrate. Another study was taken where one consumed a Red Bull energy drink, and observed that they maintained a 60% to 75% maximum heartrate. When your rate is already working harder from a simple drink, and you add rigorous exercise, it is possible to push your heart beyond its limits and ultimately, have heart failure.
Many doctors and health officals advise people (especially young adults) to not consume energy drinks as a normal beverage, and to not participate in rigorous exercise immediately after consuming an energy drink (i.e. Red Bull, Amp, Monster, Rockstar)

Women residing at domestic violence shelters (S group) were nearly 11 times more likely to report that their partner had hurt or killed pets than a comparison group of women who said they had not experienced intimate violence (NS group). Reports of threatened harm to pets were more than 4 times higher for the S group. Using the Conflict Tactics Scale, the authors demonstrated that severe physical violence was a significant predictor of pet abuse. The vast majority of shelter women described being emotionally close to their pets and distraught by the abuse family pets experienced. Children were often exposed to pet abuse, and most reported being distressed by these experiences. A substantial minority of S-group women reported that their concern for their pets' welfare prevented them from seeking shelter sooner. This seemed truer for women without children, who may have had stronger pet attachments. This obstacle to seeking safety should be addressed by domestic violence agencies.
My article was about battered pets and domestic abuse. In the article it stated that woman and children who are exposed to abuse are usually exposed to animal cruelty aswell. That maybe the abuser was at first letting its anger out on the pet or on the pet to get back at the child or the other domestic partner if they had a emotional attachment with the pet.

Hey Mr.Dillman
I hope im doing this right if im not please correct me Tooney..
I did my research on it Velvet Ants because I been hearing if u get bit by them they can make you very sick.
Velvet ants range in size from 1/8 inch to one inch, with great variation within species. Size appears to depend upon size of host used during development. Velvet ants look like miniature walking cotton balls. One variety, Dasymutilla gloriosa, has been described as a "creosote seed with legs" due to its white, thistledown-like hairs. Red, orange, yellow, black or white bristle-like hairs, known as setae, cover the entire body. Biologists call this type of coloration "aposematic," and they used the term to refer to conspicuous warning colors of animals that predators should avoid.
Males have wings but no stingers, while females have stingers but lack wings. The heavy, deeply pitted integument (outer covering of body) functions as a suit of armor and can only be penetrated with great difficulty.
Velvets Ants are mostly found in hot desert like places. Three dozen inhabit in Arizona. There is over a 150 species of Velvet Ants. Velvet ants are active during the day, and they may be some of the first insects to hit the trail in the morning and last to settle in for the night. They retreat from high ground temperatures in the middle of the day by burrowing under debris or climbing into plants. Nectar is their preferred food. Velvet ants are active from April through November, depending upon local climate. If you see a walking velvet ant, you can be assured that it is a female.
The earliest known velvet ants come from 25 to 40-million-year-old amber found in the Dominican Republic. When harassed, and during mating, velvet ants produce an audible squeak. Velvet ants are also known as cow killers or mule killers because of their extremely painful sting. Like all wasps, they can sting multiple times. Because of their armor-like exoskeleton and painful sting, few if any animals consume this conspicuous wasp.
I hope u liked the Article. As you can tell im a big animal, and insect fan. I like the class alot..

Well im going to be talking about Air Pressure and cosmogenic isotopes productions...
okk..the cosmic ray flux increases at higher altitude as air pressure and the shielding effect of the atmosphere decrease...The altitude-dependent scaling factors are required to compensate for this effect in calculating cosmic ray exposure ages. Scaling factors in current use assume a uniform relationship between altitude and atmospheric pressure over the Earth's surface. This masks regional differences in mean annual pressure and spatial variation in cosmogenic isotope production rates. This article i think is alright..

Biological agents are organisms or toxins that can kill or incapacitate people, livestock, and crops. The three basic groups of biological agents that would likely be used as weapons are bacteria, viruses, and toxins. Most biological agents are difficult to grow and maintain. Many break down quickly when exposed to sunlight and other environmental factors, while others, such as anthrax spores, are very long lived. Biological agents can be dispersed by spraying them into the air, by infecting animals that carry the disease to humans, and by contaminating food and water.
my biological article is about dolphins and there habitat. In this article it tells you about what they eat and how they live. I hope you enjoy it =)

Within the past few decades, Eurasian Lynx Have repopulated in their former habitats which, in turn, is bringing possible conflict to livestock. The number of attacks have increased to 66-131 from 3 in 1984. Most were on Lambs and subadult sheep. Some flocks were attacked once or twice a year with a 14%-59% sheep loss from Lynx. 1-6 sheep were killed on average per attack. Small areas, or "Hot Spots", that had a concentration of lynx attacks had a high population of Roe Deer but the Lynx were still attacking the sheep, not due to shortage or the need for more food when raising their young. Only a few Lynx were involved. The hot sopts covered 3-4.5% of the areas where the total attacks occurred.
