Assessing the Presence of Antibiotic-Resistant Enterococcus in Reclaimed Water Used for Spray Irrigation
Reclaiming wastewater is increasing in the US to combat dwindling freshwater supplies. This water potentially contains pathogenic bacteria; therefore, we evaluated the occurrence, concentration, and antimicrobial susceptibilities of Enterococcus spp.--an important opportunistic pathogen that remains a leading cause of nosocomial infections--in reclaimed water used for spray irrigation (SI). A total of 48 wastewater effluent and SI samples were collected in 2009 and 2010 from the Mid-Atlantic and Midwest regions of the US. Enterococci were isolated using membrane filtration, confirmed using biochemical tests and PCR, and tested for antimicrobial susceptibility using the Sensititre® dilution system. We detected total enterococci and vancomycin-resistant enterococci (VRE) in 68% (27/40) and 8% (3/40), respectively, of all SI samples. VRE and vancomycin-intermediate enterococci (VIE) represented 2% (1/41) and 10% (4/41), respectively, of the total enterococci recovered from all SI sites. Our ...http://drum.lib.umd.edu/handle/1903/14576

Ultraviolet germicidal irradiation - Wikipedia
In UVGI systems the lamps are shielded or are in environments that limit exposure, such as a closed water tank or closed air circulation system, often with interlocks that automatically shut off the UV lamps if the system is opened for access by humans.. For human beings, skin exposure to germicidal wavelengths of UV light can produce rapid sunburn and skin cancer. Exposure of the eyes to this UV radiation can produce extremely painful inflammation of the cornea and temporary or permanent vision impairment, up to and including blindness in some cases. UV can damage the retina of the eye.. Another potential danger is the UV production of ozone, which can be harmful to health. The US Environmental Protection Agency designated 0.05 parts per million (ppm) of ozone to be a safe level. Lamps designed to release UVC and higher frequencies are doped so that any UV light below 254 nm wavelengths will not be released, to minimize ozone production. A full-spectrum lamp will release all UV ...https://en.wikipedia.org/wiki/Ultraviolet_Germicidal_Irradiation

Biological aerosol background characterization | (2011) | Blatny | Publications | Spie
To provide useful information during military operations, or as part of other security situations, a biological aerosol detector has to respond within seconds or minutes to an attack by virulent biological agents, and with low false alarms. Within this time frame, measuring virulence of a known microorganism is extremely difficult, especially if the microorganism is of unknown antigenic or nucleic acid properties. Measuring "live" characteristics of an organism directly is not generally an option, yet only viable organisms are potentially infectious. Fluorescence based instruments have been designed to optically determine if aerosol particles have viability characteristics. Still, such commercially available biological aerosol detection equipment needs to be improved for their use in military and civil applications. Air has an endogenous population of microorganisms that may interfere with alarm software technologies. To design robust algorithms, a comprehensive knowledge of the airborne ...http://spie.org/Publications/Proceedings/Paper/10.1117/12.887033

Results from a Swedish survey - investigations in operating rooms
A survey is presented with data from 27 operating rooms in four county councils, where air flows, concentration of airborne viable particles and used clothing systems have been given from 111 ongoing surgeries. With the results from the survey, a simple mathematical expression based upon the dilution principle has been established to predict the concentration of airborne viable particles present in the operating room during ongoing surgery. This expression has shown relatively good agreemtn with reported results from ongoing surgery.http://publications.lib.chalmers.se/publication/196775-results-from-a-swedish-survey-investigations-in-operating-rooms

5. All life on Earth is doomed if we do not manage to get the heck out of here. Look at it this way. If there were no Homo sapiens on the Earth all complex multicellular life on the planet will be gone in about 700 million years. Our Sun is on the main sequence, burning hydrogen into helium in its core through nuclear fusion. In doing so it turns four hydrogen protons into one helium nucleus at a temperature of 15 million oK or 27 million oF in a core with a density that is 150 times greater than that of water. Surprisingly, the Sun's core only generates about 280 watts per cubic meter (a cubic meter is a bit more than a cubic yard). That means you need about 5 cubic meters of the Sun's very dense core with a mass of 750,000 kg or 825 tons just to generate the heat produced by a little plug-in space heater. Since the human body generates about 120 watts of heat just sitting still, and you could squeeze lots of people into a cubic meter if you really tried, that means that the human body gives ...http://softwarephysics.blogspot.com/2015_11_01_archive.html
How Viruses Work | ProteKdo - Empower for Health
Standard influenza is typically spread by people sneezing or coughing virus-laden particles into the air, which others breath in. Another way is by touching infected surfaces and then scratching your nose, eyes, face or ears. Viruses can live up to two days on surfaces which is why it is important to wash your hands and wipe down door handles, keyboards, machines, counters and other areas regularly. Another way to protect from airborne viruses is to use a spray bottle or diffuser with essential oils or natural formula. A simple spritz in the air will help neutralize those airborne critters while making your office, home or car smell great. Don't use lysol to spritz unless critical as this product as some studies have shown that continual inhalation of these chemicals has potential side effects ...http://empowerforhealth.com/how-viruses-work/
Presented by - Mark Evans. What are microbes? A microorganism (from the Greek: μικρός, mikrós, "small" and ὀ ργανισμός,...
Microorganisms live in all parts of the biosphere where there is liquid water, including soil, hot springs, on the ocean floor, high in the atmosphere and deep inside rocks within the Earth's crust. Microorganisms are critical to nutrient recycling in ecosystems as they act as decomposers. As some microorganisms can fix nitrogen, they are a vital part of the nitrogen cycle, and recent studies indicate that airborne microbes may play a role in precipitation and weather. Microbes are also exploited by people in biotechnology, both in traditional food and beverage preparation, and in modern technologies based on genetic engineering. However, pathogenic microbes are harmful, since they invade and grow within other organisms, causing diseases that kill humans, other animals and plants. But they have a lot of uses too. Let's discuss about some of them.http://slideplayer.com/slide/4023163/
WiFi Networks Could Be Used To Transmit Computer Viruses - Redorbit
Watch the Video: Computer Viruses Go Airborne ]. Lee Rannals for redOrbit.com - Your Universe Online. University of Liverpool researchers have demonstrated how computer viruses could go airborne over WiFi networks.. The team has shown for the first time how WiFi networks could be used to make a computer virus contagious through the air, moving through densely populated areas as effectively as the common cold.. The researchers designed a virus known as "Chameleon" and simulated how it could move through these networks. They found that not only can Chameleon spread quickly between homes and businesses, but it was able to avoid detection and identify WiFi access points that are not protected by encryption and passwords.. The computer scientists performed a simulated attack on Belfast and London in a laboratory setting, finding that Chameleon behaved like an airborne virus by traveling through WiFi networks that connect households and businesses..
