Walkerton E. Coli Outbreak
The Walkerton ''E. coli'' outbreak was the result of a contamination of the drinking water supply of Walkerton, Ontario, Canada, with ''E. coli'' and ''Campylobacter jejuni'' bacteria. The water supply was contaminated as a result of improper water treatment following heavy rainfall in late April and early May 2000, that had drawn bacteria from the manure of nearby cattle used to fertilize crops into the shallow aquifer of a nearby well. The first reported case was on May 17. The contamination caused gastroenteritis and sickened more than 2,000 people and resulted in seven deaths, and left others with chronic illnesses. Subsequently, Associate Chief Justice of Ontario, Dennis O'Connor led an inquiry into the outbreak, called the ''Walkerton Inquiry''. Walkerton Public Utilities Commission operators Stan and Frank Koebel, neither of whom had any formal training, were sentenced on December 20, 2004, after pleading guilty to charges of common nuisance stemming from the contaminati ...

Epidemiology
Epidemiology is the study and analysis of the distribution (who, when, and where), patterns and Risk factor (epidemiology), determinants of health and disease conditions in a defined population, and application of this knowledge to prevent diseases. It is a cornerstone of public health, and shapes policy decisions and evidence-based practice by identifying Risk factor (epidemiology), risk factors for disease and targets for preventive healthcare. Epidemiologists help with study design, collection, and statistical analysis of data, amend interpretation and dissemination of results (including peer review and occasional systematic review). Epidemiology has helped develop methodology used in clinical research, public health studies, and, to a lesser extent, basic research in the biological sciences. Major areas of epidemiological study include disease causation, transmission (medicine), transmission, outbreak investigation, disease surveillance, environmental epidemiology, forensic ...

CKNX-FM
CKNX-FM is a Canadian radio station, which broadcasts at 101.7 FM in Wingham, Ontario. The station broadcasts a hot adult contemporary format as ''101.7 The One''. The station was formerly known as ''FM102'' before summer 2006. History The station was launched on April 17, 1977 by Blackburn Radio, the owner of the city's existing CKNX 920 AM and former owner of CKNX-TV, which is now owned by Bell Media. Blackburn subsequently launched another FM station in Wingham, CIBU-FM, in 2005. In 1987, CKNX Broadcasting Limited (CKNX Broadcasting) was denied a license to establish rebroadcasters of CKNX-FM Wingham at Owen Sound (50 watts on 103.7 MHz) and Meaford (80 watts on 105.5 MHz). On August 29, 1989, the CRTC approved CKNX Broadcasting Limited application to establish a low-power rebroadcast FM transmitter in Centreville, on 104.9 MHz to serve Centreville and Meaford with 5 watts.

Boil-water Advisory
A boil-water advisory (BWA), boil-water notice, boil-water warning, boil-water order, or boil order is a Public health, public-health advisory or directive issued by governmental or other health authorities to consumers when a community's drinking water is or could be contaminated by pathogens. Under a BWA, the Centers for Disease Control and Prevention recommends that water be brought to a rolling Boiling, boil for one minute before it is consumed in order to kill protozoa, bacteria, and viruses. At altitudes above , boiling should be extended to 3 minutes, as the lower boiling point at high altitudes requires more time to kill such organisms. A boil water advisory usually lasts up to 24-48 hours, but sometimes more. BWA's are typically issued when monitoring of water being served to consumers detects ''Escherichia coli, E. coli'' or other microbiological indicators of sewage contamination. Another reason for a BWA is a failure of distribution system integrity evidenced by a lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diarrhea
Diarrhea (American English), also spelled diarrhoea or diarrhœa (British English), is the condition of having at least three loose, liquid, or watery bowel movements in a day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour. This can progress to decreased urination, loss of skin color, a fast heart rate, and a decrease in responsiveness as it becomes more severe. Loose but non-watery stools in babies who are exclusively breastfed, however, are normal. What is diarrhea? How is it caused, treated and prevented? (see also script)The most common cause is an infection of the intestines due to a virus, bacterium, or parasite—a condition also known as gastroenteritis. These infections are often acquired from food or water that has been contaminated by feces, or directly from another person who is infected. The three types of diarrhea ...

Disc Harrow
A disk harrow is a harrow (tool), harrow whose cutting edges are a row of concave metal discs, which may be scalloped or set at an oblique angle. It is an list of agricultural machinery, agricultural implement that is used to tillage, till the soil where crops are to be planted. It is used to chop up unwanted weeds or crop residue. It is also one of the many soil cultivation implements alongside tilers and moldboard plows. It consists of many carbon steel discs, and sometimes longer-lasting boron steel discs, which have many varying wikt:concave, concavities and disc blade sizes and spacing (the choices of the latter being determined by the final result required in a given soil type) and which are arranged into two sections ("offset disk harrow") or four sections ("tandem disk harrow"). When viewed from above, the four sections would appear to form an "X" which has been flattened to be wider than it is tall. The discs are also wikt:offset, offset so that they are not parallel w ...

Fecal Coliform
A fecal coliform (British: faecal coliform) is a facultatively anaerobic, rod-shaped, gram-negative, non- sporulating bacterium. Coliform bacteria generally originate in the intestines of warm-blooded animals. Fecal coliforms are capable of growth in the presence of bile salts or similar surface agents, are oxidase negative, and produce acid and gas from lactose within 48 hours at 44 ± 0.5°C.Doyle, M. P., and M. C. Erickson. 2006"Closing the door on the fecal coliform assay."''Microbe'' 1:162–163. . The term thermotolerant coliform is more correct and is gaining acceptance over "fecal coliform". Coliform bacteria include genera that originate in feces (e.g. ''Escherichia'', ''Enterobacter'', ''Klebsiella'', ''Citrobacter''). The fecal coliform assay is intended to be an indicator of fecal contamination; more specifically of '' E. coli'' which is an indicator microorganism for other pathogens that may be present in feces. Presence of fecal coliforms in water may not be direct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mean
A mean is a quantity representing the "center" of a collection of numbers and is intermediate to the extreme values of the set of numbers. There are several kinds of means (or "measures of central tendency") in mathematics, especially in statistics. Each attempts to summarize or typify a given group of data, illustrating the magnitude and sign of the data set. Which of these measures is most illuminating depends on what is being measured, and on context and purpose. The ''arithmetic mean'', also known as "arithmetic average", is the sum of the values divided by the number of values. The arithmetic mean of a set of numbers ''x''1, ''x''2, ..., x''n'' is typically denoted using an overhead bar, \bar. If the numbers are from observing a sample of a larger group, the arithmetic mean is termed the '' sample mean'' (\bar) to distinguish it from the group mean (or expected value) of the underlying distribution, denoted \mu or \mu_x.
