You’re outside in the yard with your family or at the local park. Maybe you’re hanging out with your friends at the mall or skate park. A typical beautiful day; having fun, keeping busy, staying healthy. But wait! What are you breathing in as you go about your typical day? Everyday you are breathing the air around you, wherever you happen to be. You can’t see it but you can feel it as you breath and sometimes you can smell it. But what is it? Does it matter? Can air quality affect your health? Yes! The air your breath does matter. Even though you can’t see it and sometimes can’t smell it, the air around you can contain toxic particles that can make you sick. A simple experiment will let you know exactly what you’re breathing and what it can mean to your health.

Our lungs absorb oxygen from the air and pass it into our blood stream so it can be transported throughout our bodies. Oxygen is important for our whole body as it provides energy we need to survive.

If you are considering a career in funeral services, you will soon discover that mortuary science schools offer certification as well as associate and bachelor degrees in the art of funeral-related services. Trade schools and vocational schools sometimes can provide entry-level training in mortuary sciences, while colleges and universities offer advanced mortuary science education.

Mortuary science is a specialized field that provides important services for every community, everywhere. Morticians must be prepared to offer compassion and guidance to people in grief, and there are few vocations that provide a greater sense of service to others than funeral service. You will be also be expected to understand the practical aspects of mortuary sciences, including the proper and legal methods for transporting and storing of deceased human bodies, as well as embalming, burial, cremation, and much more.

Over the years, a debate has taken place in the flooring
industry over the impact its products have on the
environment. In 2003, a group of industry researches and
technical specialists met at the University of North Carolina
to examine the science with regard to the positive or
negative attributes of materials found in products like
carpeting, area rugs and linoleum.

The panel looked at hundreds of studies in relation to how
carpet and non-carpet materials contribute to environmental
quality and whether there’s a significant concern with toxic
substances and allergens alleged to have commonly been
found.

The beauty and tranquility that a water garden adds to any outdoor area is more than enough incentive to create one of these stunning landscaping features in your backyard. However, there are benefits to a water garden that go beyond the pleasant hedonism of enjoying the unique aesthetic pleasures of a water garden. A water garden is as great for the environment as it is pleasant for homeowners.

The negative ions that moving water releases into the atmosphere help to purify the air. If you’ve ever noticed that air smells and tastes fresher near a waterfall or just after a rain storm, you have had a firsthand experience of the impact that these ions can have. A water garden produces a continual stream of negatively charged ions that help to remove toxins and impurities from the atmosphere. When you take a deep breath of the fresh, clear air that hovers around your water garden, you will find tangible proof of the fact that your garden is having a positive impact on the environment as a whole.

For the last 140 years, scholars have been preoccupied with identifying the exact factors that influence one’s IQ. The numerous studies on the subject have led most scientists nowadays to the belief that one’s IQ is determined by a variety of both genetic and environmental factors, although there is contention about the exact weight of each.

The majority of studies on intelligence have shown that environmental factors account for about 25% of the differences in people’s IQ scores. The factors that have been of greatest interest to scholars include prenatal development, nutrition, birth order, home and family environment, and the effects of schooling.

Airsoft, like any other sport, involves many scientific principles that go relatively unnoticed. In the heat of battle, one rarely worries about something like the transfer of kinetic energy. While knowing airsoft physics will not realistically help you in a game, the principles are good to know. Knowledge of pellet ballistics, on the other hand, can help you with your game.

Pellets transfer very small amounts of kinetic energy mainly because of their size. The transfer of energy is basically the power of impact. Airsoft and paintball energy transfers have been compared, and paintball transfers substantially more energy. Energy transfers are measured in joules, the SI derived unit of energy. A standard .20g BB traveling at 300ft/s transfers .8 joules, while a standard paintball traveling at the same speed transfers almost 12 joules. Energy transfer can actually be calculated using a mathematical formula; E = 1/2mv2, where E is joules, m is mass in kilograms, and v is velocity in meters per second. Since paintballs transfer more kinetic energy, they could be considered more damaging than airsoft pellets.

Psychology is commonly defined as ’scientific’ study of human behavior and cognitive processes. Broadly speaking the discussion focuses on the different branches of psychology, and if they are indeed scientific. However, it is integral in this to debate to understand exactly the major features of a science, in order to judge if psychology is in fact one. There must be a definable subject matter - this changed from conscious human thought to human and non-human behavior, then to cognitive processes within psychology’s first eighty years as a separate discipline. Also, a theory construction is important. This represents an attempt to explain observed phenomena, such as Watson’s attempt to account for human and non-human behavior in terms of classical conditioning, and Skinner’s subsequent attempt to do the same with operant conditioning. Any science must have hypotheses, and indeed test them. This involves making specific predictions about behavior under certain specified conditions.

Science is meant to be objective and unbiased. It should be free of values and discover the truths about what it is studying. Positivism is the view that science is objective and a study of what is real. For example, schizophrenia, when diagnosed as being caused due to excess dopamine, is being studied in a scientific manner. The explanation does not take into account any cultural customs or individual differences that might lead to ’schizophrenic’ behavior. However, even in scientific research like this the person is doing the diagnosing has his or her own views, and may misinterpret behavior because of his or her own subjective biases. For example, if someone talks about hearing voices, they may be referring to a spiritual experience, but a medical practitioner might well diagnose schizophrenia. So objective, value-free study is not easy, because the scientist has views and biases, and cultural or other issues are perhaps important factors. Some say that a truly objective study is not possible, and that a scientific approach to the study of people is not desirable.
