PART 3. MINIMIZING HEALTH RISKS 8. Wastewater Treatment for Pathogen Removal and Nutrient Conservation: Suitable Systems for Use in Developing Countries: International Development Research Centre Document(s) 12 of 23 Blanca Jiménez, Duncan Mara, Richard Carr and François Brissaud1 This chapter summarizes the main characteristics of wastewater treatment processes, especially those suitable for use in developing countries, from the perspective of their potential to produce an effluent suitable for safe agricultural irrigation; it thus concentrates on pathogen removal and nutrient conservation. Wastewater treatment processes are divided into two principal categories: ‘natural’ systems which do not rely on the consumption of large amounts of electrical energy and which are therefore more suitable for use in developing countries; and conventional electromechanical systems which are wholly energy-dependent and which, if used in low income regions, require high levels of financial investment for their construction and skilled manpower for their successful operation and maintenance.

I'm Popular I'll never get caught. I'm Popular., 10/04/05, -samy (technical explanation and actual code here) Update 11/02/05: Today I learned that the same time my account got removed, so did "embed"s from people's profiles. Update 11/01/05: My new account has been deleted/removed somehow. Update 10/19/05: No word from MySpace. A few months back, I decided to make a permanent myspace account so that I could easily view pictures of random girls whenever I please without creating a new account each time. I began to examine the site some more, seeing how they restrict things, what they restrict, taking some breaks to look at profiles of girls, trying to add them as friends and getting rejected, and getting back to making my profile cool so that they would add me as a friend later. Let's see here...what would make my profile rock. But it wasn't enough. But it wasn't enough. If I can become their friend...if I can become their hero...then why can't their friends become my friend...my hero. Postmortem:
BioMed Central | Full text | Use of and attitudes to a hospital In this hospital, we have found that the medical secretaries use the HIS more extensively for their tasks than the nurses and the physicians. Also, they are much more satisfied with the HIS. Medical secretaries reported that they use the HIS routinely for most of the tasks defined in the questionnaire (fig 3). A simple explanation is that their tasks generally are smaller in scope and have a smaller and more easily defined range of needed information types than that of the nurses and physicians (See appendix A). Hence, the medical secretaries' tasks should be more easily supported by computers than the nurses' and the physicians' tasks. The medical secretaries reported that all of the tasks in their questionnaire are more easily performed (fig 4). Not surprisingly, the medical secretaries were more satisfied with the system than the nurses and the physicians (figs 3 and 4). Limitations of the study
BusinessDay - Get SA’s gambling house in order JUDGE NB Tuchten's judgment in the North Gauteng High Court last week, declaring online gaming illegal, is a major victory for SA's gaming authorities. For the past six years, online casino group Piggs Peak has maintained that because its online casino is operated outside SA, it is not breaking any laws. However, Judge Tuchten ruled that section 11 of the National Gambling Act prohibits gaming as a whole, and it does not matter that the casino is based outside the country. While Piggs Peak plans to appeal the judgment, the groundbreaking ruling has forced the group and its rival, Silversands, to suspend the online services they offer to South Africans until their appeal has been heard. That is exactly what the Gauteng and national gambling boards have been fighting for all these years. However, it may prove to be a pyrrhic victory, as the enforcement of prohibition fails to grasp the very prickly nettle that is online gambling.
Object moved Contamination of soil with helminth eggs in the samples of fields, kitchen gardens, yards and composts in rural areas of Lodz district (Poland) was investigated. In this study, helminth eggs were found in 60–100 % of field samples, in 20–100 % of yards samples, in 0–20 % of kitchen gardens samples and in 10–100 % of composts. The highest average density of helminth eggs in 100 g of soil was detected in composts (44.0), then fields (28.5) and yards (18.0). In samples taken from kitchen gardens the average density of eggs was 0.4/100/g of soil. These results showed a considerable infestation of soil with geohelminth eggs of the examined rural areas of Lodz district which is a potential source of antropozoonosis.

Talking to the Police All the Time I started writing this entry while thinking about the "if you have nothing to hide, then you have nothing to fear" fallacy. What do you say to someone who says that they have nothing to hide, or that some information about them is worthless anyway, so they don't care about some violation of their privacy? What do you say to a police officer who says that if you have nothing to hide then you have nothing to fear by answering questions? It implies that if you refuse to answer then you're probably "not innocent". That "pleading the 5th" is now used as a joke to admit guilt in light banter, is a sign of how pervasive the fallacy has become. Those kind of statements expose naïveté or, if intended as a manipulative statement, perversity. You may buy some time by mentioning anecdotes such as the man falsely accused of arson because by coincidence, he bought certain things in a store at a certain time (betrayed by his grocery loyalty card) [1].

I was reviewing answers to my Software and Law survey last night when I saw a tweet where someone was wondering how to claim the company name back from a Twitter user. The user doesn’t work for the company and was apparently bad mouthing the company. Several years ago I wrote an LLM paper on domain names. Well, what about cybersquatting in Twitter? Take this case: 1. 2. 3. 4. 5. With domain names, there is a procedure. ICANN has a dispute resolution policy (UDRP), and there is also specific anti-cybersquatting legislation (ACPA) in the US, and there is case law and specific statute in other countries about domain name disputes. Is a Twitter handle a domain name? Twitter has responsibilities to trademark holders. The lawyers are stirring. Twitter has become a cesspool of trademark infringement and copyright infringement claims. According to this post from Steve Poland they still have a lot to learn. 1. 2. 3.

[Water Sci Technol. 2008 Congress OKs Port Security Bill WASHINGTON — Congress early this morning approved and sent to President Bush a bill aimed at shoring up anti-terrorism defenses at U.S. ports. The port security measure, which would bring millions of federal dollars to the Los Angeles-Long Beach port complex and other harbors, became a GOP priority after a political flap earlier this year over a Dubai company's ill-fated attempt to manage facilities at several U.S. ports. The measure, which Bush is expected to sign, authorizes $400 million a year in federal grants to ports for the next five years, requires minimum security standards for the nearly 11 million cargo containers that enter U.S. ports each year and establishes a pilot program at three foreign ports to scan all U.S.-bound cargo. It also sets up security training for waterfront workers and mandates radiation detectors at major ports by the end of next year. And it establishes deadlines for special identification cards to be issued to port workers after background checks. Rep.
Off-site wastewater treatment systems 4.2.3 LagoonsPonding or lagooning is effective in treating wastewater and can reduce BOD and SS to the same levels as mechanical treatment plants (e.g. Activated Sludge Treatment). In addition because of the longer residence time of wastewater in the lagoon (days), removal of pathogenic bacteria and viruses by natural die-off is greater than in an activated sludge treatment plant (residence time usually several hours). Cysts of parasites and helminth eggs are also usually removed through sedimentation in the lagoons.A lagoon is a shallow excavation in the ground (1 to 2 m deep). It is generally unlined percolation of wastewater into the soil and groundwater takes place. With time the percolation rate will reduce, because of formation of a sediment layer. Depending on the oxygen demand of the bacteria in the lagoon, the following conditions occur: Lagoon performance is affected by temperature. Soil aquifer treatment is also known as rapid-rate land application.
