...Black mold is a problem people have been dealing with for years. However, it hasn't been until recently that we are beginning to understand the negative impact it can have in our lives. Toxic types of mold do not discriminate and they are quite common. Black mold, in particular, has caused numerous health problems ranging from headaches and dizziness to full on breathing difficulties requiring hospitalization. It is for this reason, entire schools and workplaces have been shut down for mold treatment. How to Identify Black Mold This type of mold has a greenish-black appearance and a slimy texture. It can be difficult to judge by appearance alone if mold growth is black mold, but can be a good indication that it requires removal. No matter...

...worry about black mold or is all the media attention just hype? Is black mold removal really needed? If your home has a musty or earthy odor you have been ignoring perhaps you should pay attention it. What is Black Mold? Black mold is a fungus from the genus Stachybotrys. Black mold is widely distributed and there are around 50 different species of it. Toxic black mold, as the media calls it, is Stachybotrys chartarum Not all mold is bad and it is everywhere. In the outdoor environment it breaks organic matter down. Without it organic materials like leaves wouldn't decompose and would build up. Mold produces mycotoxins as it grows and feeds. It does this to keep other organisms out of its food supply. These mycotoxins seldom cause...

...works for a health care facility who has the main goal of finding ways to stop or avoid communicable epidemics in the United States. Epidemiologists study the frequency and distribution of diseases within human populations and environments. Specifically, they measure the incidence of disease occurrence and relate it to different characteristics of populations and environments. Epidemiologists perform research, education, and public health practice in universities, government agencies, international organizations, and private corporations. Therefore epidemiologists study a wide range of healthcare issues. Epidemiologist study and research regions or different populations regarding serious life threatening diseases, diseases that are infectious, the life span of illness in families a well as environmental pollutants that occur. Epidemiologists collect and further analyze important information about public health and the behavior of diseases. After researching and analyzing collections an Epidemiologist explain and also reveals to the public about the findings of their research. Epidemiologist study the distribution of health-related events in a specific population and the purpose of this study in order to control health problems that occur. “Epidemiology includes the methods for measuring the health of groups and for determining the attributes and exposures that influence health; the study of the occurrence of disease in its natural habitat rather than the controlled environment...

...Charcoal is a light, black residue, consisting of carbon and any remaining ash, obtained by removing water and other volatile constituents from animal and vegetation substances. Charcoal is usually produced by slow pyrolysis, the heating of wood or other substances in the absence of oxygen (see char and biochar). It is usually an impure form of carbon as it contains ash; however, sugarcharcoal is among the purest forms of carbon readily available, particularly if it is not made by heating but by a dehydration reaction withsulfuric acid to minimise the introduction of new impurities, as impurities can be removed from the sugar in advance. The resulting soft, brittle, lightweight, black, porous material resembles coal. Subtitle: A Boise State University study proves that low-energy feedstocks can be densified and when combusted produce heat output comparable to higher energy content fuels. By Owen McDougal, Seth Eidemiller, Nick Weires. November 23, 2010 By the way, according to one of those online dictionaries, “feedstock” refers to “the raw material that is required for an industrial process.“ Intro Research at Boise State University in Idaho, explored both the caloric content and shape to optimize burn efficiency of the biobriquettes. The energy content of briquettes ranged from 4.48 to 5.95 kilojoule per gram (kJ/g) depending on composition, whereas the energy content of sawdust, charcoal and wood pellets ranged from 7.24 to 8.25 kJ/g. Biobriquettes molded into a hollow-core...

...There has been a long debate and much research into the Nature vs. Nurture theories. Being that do we inherit traits from our biological parents or does the environments in which we are raised contribute to how we turn out as adults. Sometimes it seems that that there is no black or white answer to the age-old question of what contributes to human behavior, personality, and psychopathology. There are common traits within biological parents that children can pick up but it seems that in some cases, children can be adaptive to their environment. So we shall examine this curiosity that takes us into finding out whether we are genetically inherit to some of the biological traits of our parents or if living in certain environments develop our social well being. There have been studies into schizophrenia and the genetic traits that may be passed on to the children. The study was conducted to observe children who had biological parents who suffered from schizophrenia and their adoptive parents showed no signs of the illness. The study was also conducted on children from biological parents who showed no signs of schizophrenia adopted by a parent who later showed signs or family history of the illness. The research showed that although there is no definitive answer for what causes schizophrenia, children whose biological parents that suffered from schizophrenia had a higher recidivism rate for contracting the disease. “This study also showed that the adoptees whose biological...

...Are Leaders Born or Made? Professional Development-MBA 525 St. Leo University Bruce Hammond February 10, 2013 Abstract This paper will discuss whether the greatest leaders are made or born. While many people are born with natural, instinctive leadership qualities and traits; many people can become great leaders with the training, earned respect and situations or environment. This paper will also discuss what makes an effective leader. Paper Section Whether great leaders are born or are they made is a greatly debated subject. Some people are certainly born with leadership instinct(s) that may never be fully realized and developed. Others may have traits that may not be traditionally thought of as natural born leader traits but they possess other skills and the desire to lead that can turn them into an effective leader. "Leaders are developed. Leadership is nothing more than a collection of skills, that when employed, produces results." (Garic, 2006) In today's ever-changing job market and economy, many leaders and many types of effective leaders will be needed. Leadership development is the way to mold various personal traits: personality, talent, honesty, ability, sincerity, skill, confidence, integrity, into a good leader. As Pace states: "There are no set rules for what makes a good leader, but most successful leaders can draw on several qualities to help them lead." (Pace, 2006) Leaders draw on personal experience, as well as, training, knowledge...

...At first glance, it seems that student success is easy to obtain, attend your classes, complete your work, study the material, and you’ll succeed, Or at least that’s what students often believe. Students always view success as an option, you either want to, or you don’t. The research makes it clear that it is not so black and white. A student’s mentality towards student success can be morphed as we excavate further into research such as essays and documentaries. An analysis of the research leads us to believe that Anaheim High Schools can improve student success only if The amount of time invested in schools is increased, An emphasis is put on student effort rather than natural talent, and schools promote student involvement in extracurricular...

...magazines like it, but instead represents a larger trend that is present in all forms of Western popular culture. In the various mediums of popular culture, ideologies about female beauty are exceedingly prevalent and constantly managed and reproduced. These ideologies carry with them the notion that in order to obtain ideal female beauty one must be very thin, young, have long hair, and wear expensive or revealing clothing (Stern, 2004). In addition to this there is also a raced definition of beauty, which predominates Western popular culture and dictates that White women with light hair and eye color can only attain true beauty. By looking closely at fashion magazines, television shows, movies and advertisements it is easy to see how Asian, Black and Latina women are underrepresented and misrepresented; and more importantly beauty is not typically associated with these and other nonwhite races. The power and importance of popular culture in today’s society has further supported beauty ideologies that are racialized. Feminist and cultural scholars have often...

...minimize pest damage and protect environmental resources. Red Root Rot a Late Season Disease of Corn * Roots and basal stalk tissue infected with red root rot characteristically have reddish-pink, rotted roots. * Stalks are weakened and susceptible to lodging. * Premature plant death is common and can occur quickly and yield losses can be as high as 15-20%. * Genetic resistance to red root rot is uncommon and breeding for disease resistance is difficult. Management Management options are limited. Crop rotation with a non-host such as soybean can provide some control.1 Genetic resistance has been difficult to incorporate into corn products, although the rate of disease development varies greatly between corn products. Research on inheritance of disease resistance indicates that it is a polygenic trait with additive gene action, which has complicated breeding efforts.1 Environmental stress during the season may contribute to disease infection and severity. Sap Beetles in Corn Sap beetles are considered minor pests of corn. Adults prefer to feed on corn kernels, ear tips, and stalks that have previously been injured by other insects such as corn earworm or corn borer larvae. Controlling corn ear pests should prevent sap beetles from becoming a problem. Damage Sap beetles are...

Y., Costumbrado, J., Hsu, C. Y., Kim, Y. H. Agarose Gel Electrophoresis for the Separation of DNA Fragments. J. Vis. Exp. (62), e3923, doi:10.3791/3923 (2012). Abstract Agarose gel electrophoresis is the most effective way of separating DNA fragments of varying sizes ranging from 100 bp to 25 kb1. Agarose is isolated from the seaweed genera Gelidium and Gracilaria, and consists of repeated agarobiose (L- and D-galactose) subunits2. During gelation, agarose polymers associate non-covalently and form a network of bundles whose pore sizes determine a gel's molecular sieving properties. The use of agarose gel electrophoresis revolutionized the separation of DNA. Prior to the adoption of agarose gels, DNA was primarily separated using sucrose density gradient centrifugation, which only provided an approximation of size. To separate DNA using agarose gel electrophoresis, the DNA is loaded into pre-cast wells in the gel and a current applied. The phosphate backbone of the DNA (and RNA) molecule...
