Professor Foxson Bio 1500 Lab 9/22/14 Acinetobacter baumanii Acinetobacter baumanii is multidrug resistant and is recognized to be one of the most difficult antimicrobial-resistant gram-negative bacilli to control and treat. It can survive for a prolonged period under a wide range of environmental conditions. This organism has caused outbreaks of infection and health care associated infections. Some infections include bacteremia‚ pneumonia‚ meningitis‚ urinary tract infection and wound infection

I am going to use granite‚ concrete‚ and brick in the Grand Canyon monument to honor early explorers. I am choosing these items because I think these are some of the most high quality materials. I would like to build this monument very well‚ so that it will last for years and years. I also want to build this monument well because the early explorers worked very hard to do everything they could for the Grand Canyon‚ and I would like to honor them. Many people may have thought that everyone always

have been around for at least 30‚000 years (Luiggi 2011). In our required pre-lab reading‚ we learned tuberculosis is becoming increasingly drug-resistant‚ giving proof that bacteria can adapt to necessary changes in order to survive (Barry 2009). The addition of acetyltransferases‚ enzymes that help move acetyl groups‚ to bacteria can make it more resistant to antibiotics containing aminoglycosides (Norris 2010). An aminoglycoside is simply just an antibiotic whose structure consists of amino-modified

the disease malaria. Before that an organization in Southern Africa had produced a poison to kill these mosquitoes but it wasn’t completely successful. The produced poisons by the WHO kills most members of the insects population leaving only the resistant individuals to reproduce with new genes that somehow enable them to resist the chemical attack. The problems such insects pose are just some of the many ways that evolution has a direct connection to our daily lives considering the adaptations in

modern medicine as they are becoming more and more resistant to antibiotics. Antibiotics were discovered in 1928 by Alexander Fleming (Walsh and McManus‚ 2000). This resulted in a huge movement forward in medical history and even greatened human life expectancy. Since then antibiotics have been widely used and abused‚ people began to treat everything with this ‘miracle’ drug. If antibiotics are continually used as bacteria grows exponentially more resistant to them then eventually society will fall back

THERMAL INSULATION MATERIALS Thermal insulation materials are specifically designed to reduce the heat flow by limiting heat conduction‚ convection‚ radiation or all three while performing one or more of the following functions: The main function of insulation is to reduce the heat transfer‚ the insulation material must have the appropriate characteristic to slow down the transport of heat occurred by conduction‚ convection and radiation. Conduction loss in insulation is negligible. There are

research in medicine has brought forth antibiotics – a way of stopping harmful bacteria from infecting a person. Growing concern is centered on the fear that the overuse of antibiotics will create different types of “super bacteria”‚ or bacteria resistant to multiple kinds of antibiotics. This fear is legitimate – mankind could be fast-forwarding the evolution of harmful viruses or bacterium‚ leading

GM crops can be altered to be resistant to harsh weather conditions. These include drought-resistant‚ heat-resistant‚ and cold-resistant crops. These changes allow areas that were not previously used to grow crops due to weather conditions to be used for agricultural purposes. Drought-resistant crops allow the arid regions that receive little rainfall or are on the outskirts of deserts‚ such as the Southwest Region of the United States‚ to grow crops. Heat-resistant crops are often used in similar
