An anvil hanging vertically from a long rope in a barn is pulled to the side and raised like a pendulum 1.6 m above its equilibrium position. It then swings to its lowermost point where the rope is cut by a sharp blade. The anvil then has a horizontal velocity with which it sails across the barn and hits the floor, 10.0 m below. How far horizontally along the floor will the anvil land? "
m g h = potential energy at top = U = m (9.8)(1.6)
Ke at bottom = U at top =.5 m u^2
1.6*9.8 =.5 u^2
calculate u, the horizontal velocity from that
Now get time in the air from the falling problem
10 =.5 * 9.8 * t^2
so calculate t from that
distance horizontal= u t


Updates from Göteborg (Gothenburg)
Updates from Göteborg (Gothenburg)
In the Gothenburg project, PI Kristina Lindström has her primary focus on public space governance and how events are used as a strategic tool to fulfill societal goals of a more inclusive city. Gothenburg has a long history as a "city of events" and, as a consequence, extensive areas in the city centre are designed to meet the needs of the local event industry. However, Gothenburg is also a city suffering from segregation of marginalized groups and consequently a key challenge is how events in public space and publicly funded events can contribute to a more inclusive society. A local event industry extensively owned by the municipality calls for strategies proving societal values beyond short-term growth, which is often the case in event and tourism development.
Governance is one of the most significant influences on how events develop and eventually become a facilitator of spatial sustainable development. However, events in the urban public space is a complex governance phenomenon, cutting across several domains of governance; institutional structures, policymaking processes and underlying diverse power structures.
The complex, yet crucial, nature of governance of urban public space in the face of eventification and festivalization of the city and, other related topics were discussed when the Festspace Gothenburg project met with the innovation project "Evenemangspiloter", a pilot project with the purpose of using existing resources (e.g. public space) in innovative ways in order to prevent marginalization of residents and increase inclusion through events. Two of the stakeholders involved in "Evenemangspiloter" are Got Event and Equal City, both organizations within the municipality of Gothenburg. Got Event operates several of the city's arenas and Equal City is a long-term initiative aimed at making the city an equal city. So far, "Evenemangspiloter" has developed co-creative methods to ensure broad representations of residents in the development of alternative inclusive event strategies. One example of upcoming activity is participatory observations at events with the purpose of understanding the nature of exclusion in the event context.
It became evident "Evenemangspiloter" can offer a valuable local and inter-sectoral platform for the Festspace Gothenburg project and further, that Festspace can add research-based knowledge and benchmark opportunities to "Evenemangspiloter".
Some examples of public event spaces in the city centre of Gothenburg heavily debated in the face of increased demand for sustainability: the Ullevi Arena (above),
and Heden (below), the main arena area of the Gothia Cup, the World's largest youth soccer tournament.

Gaussian solitary waves and compactons in FPU lattices with Hertzian potentials
Proceedings of Royal Society A 470, 20130465 (2014) (20 pages)
We consider a class of fully-nonlinear Fermi-Pasta-Ulam (FPU) lattices,
consisting of a chain of particles coupled by fractional power nonlinearities
of order a > 1. This class of systems
incorporates a classical Hertzian model describing acoustic wave propagation
in chains of touching beads in the absence of
precompression. We analyze the propagation of localized waves
when a is close to unity. Solutions varying
slowly in space and time are searched with an appropriate scaling,
and two asymptotic models of the chain of particles are derived consistently.
The first one is a logarithmic KdV equation, and possesses linearly orbitally stable
Gaussian solitary wave solutions. The second model consists of
a generalized KdV equation with Holder-continuous
fractional power nonlinearity and admits compacton solutions, i.e.
solitary waves with compact support. When a approaches 1, we numerically establish
the asymptotically Gaussian shape of exact FPU solitary waves with
near-sonic speed, and analytically check the
pointwise convergence of compactons towards the limiting Gaussian profile.
Discrete FPU lattice, granular crystals, log-KdV equation, Gaussian solitary waves, linear stability.

Flesh is the soft part of the body of a person or animal which is between the skin and the bones. In ordinary speech, it typically contrasts with bone, as in the merism flesh and bone. It mainly refers to skeletal muscle and associated fat, though it includes all other internal soft tissue. The softness of a human body is generally attributed to flesh, although muscles can also give a notion of hardness.
The word "meat" is normally used instead if animal flesh is intended as food.
In some instances, the term "flesh" will be used to describe the soft interior of fruits, usually the part that is eaten.

Use of nanofluids is one of the prominent techniques in the active research of enhancing the energy utilization. In this paper, an updated review is carried out for various recent studies that illustrate the use of nanofluids in different types of solar collectors for improvement of their performance. In addition, some suggestions are made in relation to the future research directions in view of the prevailing challenges using nanofluids in solar energy systems. It has been witnessed that proper dispersion of nanoparticles is a key issue for adequate solar absorption. Improvement of solar collector performance agrees until certain limit of nanofluid volume fraction above which it can end up with adverse results. Proper combination of particle size, pH value and adequate dispersion of nanoparticles results in efficiency increment. Among all possible nanoparticles carbon nanotubes result in larger enhancement when compared to rest, in general. It is also noted that the optical properties of nanoparticles play a key role in absorption, extinction coefficient and the penetration depth of the solar radiation in the nanofluids.

It's Springtime in Chicago again, which means you can count on two things–complaints about the lingering cold weather and the Annual Illinois ASBO Conference, which is going on now in Schaumburg, Illinois. I was lucky enough to speak at the conference in Schaumburg yesterday on a couple of topics, one of which was Technology and School Law: Why Ignorance Is Not Bliss. In that talk, the issue of posting student photographs online led to a lively discussion. As the article "Posting Pictures to a School Website" explains, digital cameras and camera phones allow us to take photos and post them online much faster than ever before. Once there, photographs are there to stay, even if someone tries to erase them, and are simple to locate. So it's especially important to think (before you post!) whether doing so would violate federal and state student records laws. Here are some of the key takeaways we discussed:
- Before posting a photograph online, a school employee or agent (like a parent volunteer or student working on a school-related project) should always consider whether doing so would violate laws protecting student/educational records. Both the federal Family Educational Rights and Privacy Act (FERPA) and related state laws, such as the Illinois School Student Records Act (ISSRA), generally allow a parent/guardian (or student if over the age of 18) to control whether third parties outside of the school environment can see a student's records.
- There are two essential questions to ask in this circumstance: (1) Is a photograph a student/educational record under these laws? and (2) If it is, does an exception allow its publication without the express, written consent of the student's parent/guardian (or the student if over age 18)? If a photograph is a student record and there is no exception, it should not be published or shared with any third party without the required consent, including posting online.
- If the photograph is not a close up of the student and the student is not named along with it, is it even a student record? We discussed that there are some valid arguments that can be made that a group shot in which a student cannot be easily identified is not a student record. We don't know the definitive answer to this question, but I know as a practical matter many schools assume they are not, and post such photographs without any notice to or consent by parents/guardians, and I think there are strong legal arguments to support that view.
- If the photograph is clearly of the student but doesn't name the student, is that a student record? Again, reasonable minds can disagree on this point. The more cautious, conservative approach is to treat such photographs as student records, although again there are good arguments both ways.
- If a photograph is a student record, some ask, why not just get consent? Well any of us who work with social media know that the beauty of the medium is its speed. If you have to obtain express consent after snapping a photo but before posting it, the logistical hurdle might be insurmountable in some cases, but at the very least will slow things down. Will people still care about that photo from today's activity later this week? If you have to get consent every time, it may grind your social media and other online presence to a halt.
- What about directory information? Under FERPA, photographs can be treated as directory information, meaning that as long as parents/guardians (and students over age 18) are given general notice that photographs might be published and an opportunity to opt out, photographs of the student can be posted without express consent. State law can be tricker, but assuming your state law allows you to consider a photograph as directory information, does this exception save the day? The answer is it can, with proper notice and training to your staff and agents. Each time one of those people posts a photograph that identifies a student, they should consult the directory information list to make sure that a student identified in the photograph is not on the opt out list. (Remember, there may be special issues with students with nicknames and student with special situations, such as transgender students and students in protective custody who might not want to (or by law should not) be included in a photograph open to the general public). But otherwise, if a student is not on the opt out list, and the photograph is directory information, your student records concerns should be addressed.
- What if the student is engaging in an activity open to the general public? Again, the law is unclear here, but is it really practical for the lead of the school play or the student walking across the graduation stage to opt out of being in photographs or videos of the event? At the very least, schools should make explicitly clear to students before they engage in such events or activities if photographs, videos, or other recordings will be taken and shared without regard for any opt outs on directory information lists.
This was just one of many topics we discuss about posting photographs (including one of my favorite stories about the potential to breach student privacy, or at least embarrass students, through sharing their photographs in the school realm). To mitigate all of the pitfalls related to posting student photographs online, school officials should have a conscious plan for what rules employees and agents of the school must follow when posting photographs of students online, and take steps to ensure that that plan is followed closely.

An improved maintenance management strategy for gas field equipment in Escravos gas–to–liquid plant, Nigeria
Onyenanu, Tochukwu Emmanuel
MetadataShow full item record
The safety record of most petrochemical industries in the world and Nigeria in particle, has not been able to come down to the maximum allowable range of 0 - 0.1 percent of tolerance on recordable injuries, due to increasing failure rates of equipment within the plant. Investigations on the maintenance audit carried out on the Nigerian Gas Company (NGC) revealed that 85 percent of such failures are directly linked to improper adaptability of an effective maintenance management strategy and plan within the petrochemical industries in Nigeria. Equally, the growth and continuous operation of any plant depends to a large extent on the maintenance of the equipment that refines the Crude Oil and natural Gas. As such, various maintenance management systems have been used over the years for the actualisation of the above purpose but with minimal success. This is evident in the fact that the level of maintenance performance of most Nigerian Petroleum Companies is always on the corrective maintenance model, which indirectly implies that the plant normally breaks down before maintenance management is applied. A critical look at the deficiency of improper adaptability of these maintenance management plans have conspicuously manifested in five major categories of maintenance failures which includes the following; * Failure of safety critical equipment due to lack of maintenance * Human error during maintenance * Static or spark discharge during maintenance in an intrinsically unsafe zone * Incompetence of maintenance staff, and * Poor communication between maintenance and production staff. These gaps as identified in this research must be corrected in the Nigerian Gas Industry if meaningful progress is to be made. Gas – To – Liquid technology is a very complex technology and with natural gas as the basic raw material, the technology not only looks intimidating but also is full of potential hazards. People are naturally afraid of the complex nature of gas in a confined environment (because of its highly combustible nature), its gaseous state makes it more complex for it to be kept under control and at the same time be moved from one form to another at different temperatures and pressures. The maintenance audit carried out on the Nigerian Gas Company (NGC) revealed some major loopholes in the maintenance management strategies adopted in the country. The audit reveals that the degree of adherence to conditions attached towards the maintenance management strategy of this equipment (in this case Gas field equipment) was too poor. Based on the above, this research is meant to improve the existing maintenance management strategy, by developing a Maintenance Management Strategy (MMS) that will be suitable for gas field equipment in the Escravos Gas–To– Liquid (EGTL) plant, planned to be commissioned in Nigeria early 2011. The need to research the above mentioned Maintenance Strategy became imperative due to the fact that the rate at which most of the petrochemical plants in the world are being gutted by fire, mainly due to poor maintenance management systems is alarming. This research work proffered solutions that will reduce or completely eliminate the highlighted problems above. This was based on investigations and analysis carried out in the chosen research area. Models were developed for the actualization of this Improved Maintenance Management Strategy (IMMS), so that the desired safe operability of the gas field equipment in the Escravos Gas–To– Liquid (EGTL) plant will be achieved without maintenance failure of any kind.

Posted on (Answer #1)
You need to evaluate pH using the following equation, such that:
'pH = -log(NaOH)'
Since the problem provides the concentration of '0.002M', you need to replace it in formula above:
'pH = -log(0.002) => pH = -(-2.69) => pH = 2.69'
Hence, evaluating the pH of the '.002 M NaOH' solution yields 'pH = 2.69.'

Flood Hydrology Modeling: U.S. Virgin Islandsby James E. Scholl, CH2M Hill, Gainesville, FL, USA,
Document Type: Proceeding Paper
Part of: Engineering Hydrology
To develop a consistent basis for evaluating existing flooding problems and for planning activities to reduce future flood damage, a watershed modeling project was initiated by the Government of the U. S. Virgin Islands in 1979. This paper summarizes the procedures utilized to model flood hydrology in the U. S. Virgin Islands, presents results of hydrograph analysis performed using observed streamflow data, and concludes by briefly summarizing the status of watershed modeling performed to date. Flood hydrographs were developed for 10-, 25-, 50-, and 100-year design storm conditions using the HYMO computer program. Thirteen major watersheds in the Islands were evaluated using HYMO, and conceptual solutions to flooding problems were developed.

This book is the result of a major research project in Local Economic Development at the University of Waterloo. It is a unique guide to Hamilton; encouraging residents and visitors alike to explore and learn about how its location, history and environment are influencing its path to revitalization as a post-industrial city. (108 full colour pages, packed with photos and maps)
Strategic Interchange releases two new reports on the Hamilton Rapid Transit project: A cost-benefit analysis and development uplift study. The cost-benefit analysis reveals that with full-funding from Metrolinx, light rail (LRT) is the best choice for the A-Line and B-Line rapid transit routes. The cost of not doing LRT to the City of Hamilton is over half a billion dollars over 25-years. The second report, studying development uplift potential along the B-Line, reveals nearly $1 billion in new development, $20 million in additional property tax annually and $52 million in development charges, based on design concepts for 6 rapid transit station sites. These reports are based on Ian Dunlop's masters-level academic work at the University of Waterloo in economic analysis and land development planning.
Ian Dunlop, is enrolled at the University of Waterloo, Faculty of Environment to complete a Masters of Applied Environmental Studies in Local Economic Development.
Strategic Interchange became a member of the Hamilton Chamber of Commerce.
"Welcome Cyclists" signs, designed by Strategic Interchange for Transportation Options and Northumberland Tourism, have been installed at 9 locations along the Waterfront Trail in Northumberland County, about 1 hour east of Toronto. The signs are gateway markers, located at Cobourg, Port Hope, Brighton and Colborne, welcoming trail users to these cyclist-friendly communities. A sign is also located at the Coboury VIA train station, as promoting of the Bike-Train initiative. Follow the link to the official press release on the Northumberland website.

Cluster algebras associated to quivers are additively categorified by categories modeled on quiver representations. Stability conditions and scattering diagrams of these categories are remarkably linked with the corresponding cluster algebras. I will first introduce scattering diagrams valued in graded Lie algebras in full generality and explain Kontsevich-Soibelman's classification theorem. A canonical cone complex structure of a scattering diagram will be given. Then I will define Bridgeland's stability scattering diagrams associated to quiver with potentials and explain how they can be used to study the corresponding cluster algebras.


Sertraline (Lustral)
Sertraline is an antidepressant medicine used to treat various anxiety disorders as well as depression - we explain everything you need to know about taking it
What is sertraline used for?
Sertraline is used to treat the following conditions in adults:
Advertisement - Continue Reading Below
How does sertraline work?
Sertraline hydrochloride is a type of antidepressant known as a selective serotonin reuptake inhibitor (SSRI). It works by enhancing the activity of a neurotransmitter called serotonin in the brain.
Neurotransmitters are natural body chemicals that act as chemical messengers between the nerve cells. Serotonin is a neurotransmitter known to be involved in regulating emotions, mood and behaviour, among other things. In depression and anxiety disorders there is a decreased amount of serotonin released from nerve cells in the brain.
Sertraline works by stopping the serotonin that has been released from being reabsorbed back into the nerve cells in the brain. This helps to prolong its effects and over time this helps to lighten mood and relieve depression. Antidepressants like sertraline have also been found to be effective in relieving symptoms of anxiety, such as panic and fear.
Sertraline won't change your personality or make you feel instantly happy and relaxed. It works over time to correct the chemical changes in your brain that have made you become depressed or anxious, and gets you back to feeling like your old self.
How long does sertraline take to work?
 - It can take between two to four weeks of taking sertraline before it starts to work, so it's very important that you keep taking it, even if it doesn't seem to make much difference at first. You'll usually need to keep taking sertraline every day for several months, and for at least six months after you feel better. You should keep taking it for as long as your doctor asks you to.
 - If you feel your depression has got worse, or if you have any distressing thoughts, or feelings about suicide or harming yourself in the first few weeks, or at any point during treatment or after stopping treatment, then it is very important to talk to your doctor.
 How do I take sertraline?
 - The sertraline dose your doctor prescribes will depend on the condition being treated. If you have an anxiety disorder your doctor may start you on a low dose and increase this after the first week of treatment. It is important to follow the instructions given by your doctor. Remember that it takes a while for sertraline to start working, so keep taking it as prescribed even if it doesn't seem to make much difference at first. Do not take more than the dose prescribed by your doctor.
 - Your sertraline dose should be taken once a day. You can take your dose at any time of day, but try to always stick to the same time - this will also help you remember to take it.
 - Sertraline tablets can be taken either with or without food, on a full or empty stomach.
 - If you forget to take a dose of sertraline at your usual time, take it as soon as you remember that day. If you don't remember until the following day, just leave out the missed dose and take your next dose as usual. Do not take a double dose to make up for a missed dose.
 - You should keep taking sertraline every day for as long as your doctor asks you to. With depression it's normal for your doctor to ask you to keep taking it for at least six months after you feel better, as this has been shown to reduce the risk of your depression coming back.
 - Do not suddenly stop taking sertraline unless your doctor tells you to, as this can cause withdrawal symptoms such as dizziness, sleep disturbances (including intense dreams), headache, feeling sick or weak, sweating, pins and needles, burning or electric shock sensations and feeling anxious. Withdrawal symptoms are temporary and are not due to addiction or dependence on the medicine. They can usually be avoided by stopping the medicine gradually, usually over a period of weeks or months, depending on your individual situation. Follow the instructions given by your doctor when it's time to stop treatment with this medicine. On very rare occasions some people have experienced withdrawal symptoms after accidentally missing a dose of sertraline.

 What should I know about taking sertraline?
 - You should avoid drinking grapefruit juice while taking sertraline, as this may affect the level of sertraline in your blood and could increase the risk of getting side effects.
 - Selective serotonin re-uptake inhibitor (SSRI) antidepressants like sertraline have sometimes been associated with unpleasant or distressing restlessness and feeling as though you need to move, often accompanied by an inability to sit or stand still. This is most likely to occur within the first few weeks of treatment if it's going to affect you. If you experience these symptoms you should consult your doctor.
 Can I drive while taking sertraline?
 - Sertraline may reduce your ability to drive, operate machinery or ride a bike. For example it may reduce your ability to concentrate and may make some people feel tired or dizzy. Do not drive or operate machinery until you know how this medicine affects you and you are sure it won't affect your performance.
 Can I drink alcohol while taking sertraline?
 - Drinking alcohol in moderation while you're taking sertraline shouldn't cause problems for most people, though if you find the medicine makes you feel tired or dizzy then alcohol could make this worse. However, it's usually recommended that you avoid drinking alcohol while taking antidepressants because alcohol can make depression worse. If you want to drink alcohol you should get advice from your doctor about whether this is a good idea for you.
 Who may need a lower sertraline dose or extra monitoring?
 - Elderly people.
 - People with a history of mania or hypomania.
 - People who are also having electroconvulsive therapy (ECT).
 - People with kidney or liver problems.
 - People with diabetes. Sertraline may alter the control of your blood sugar. As a result, you may need an adjustment in your dose of insulin or antidiabetic tablets. Discuss this with your doctor.
 - People with epilepsy. Tell your doctor if you experience more seizures than normal after starting sertraline.
 - People with heart disease such as heart failure, a recent heart attack or a slow or irregular heartbeat.
 - People with a low level of potassium or magnesium in their blood.
 - People with a history of bleeding disorders, particularly bleeding in the gut.
 - People taking medicines that affect blood clotting, such as warfarin.
 - People with raised pressure in the eye or glaucoma.
 - Sertraline is not licensed for treating depression in children and adolescents under 18 years of age. However, some specialists may still prescribe it if they feel it is essential. If your child is prescribed sertraline for depression or OCD it is very important that they are encouraged to report any distressing feelings, thoughts about suicide or self-harm, irritability, aggressive behaviour, mood changes or other unusual change in behaviour that they may experience while taking the medicine. If you notice a change in your child's behaviour, or are worried about them at any point, it is important to talk to your doctor immediately.
 Who should not take sertraline?
 Can I take sertraline if I'm pregnant or breastfeeding?
 - Ideally sertraline should not be used during pregnancy. However, the reality is that depression can strike women during pregnancy and women taking antidepressants can also get pregnant or want to plan a baby. It may be necessary for some women to take sertraline during their pregnancy in order for them to remain well during the pregnancy and be able to care for their baby.
 - It is important to talk to your doctor about the risks and benefits of taking sertraline during the pregnancy compared with stopping treatment or using other treatments. This is particularly important in the first and third trimesters, where sertraline could potentially have harmful effects on the baby. For example, SSRI antidepressants may carry a slightly increased risk of causing heart defects if taken in the first trimester, and symptoms that resemble side effects or withdrawal symptoms of sertraline have been seen in new-born babies whose mothers took this medicine in the third trimester.
 - It's important to get medical advice from your doctor if you think you could be pregnant or want to plan a pregnancy while taking sertraline. If you decide to stop taking sertraline you doctor will advise you how to do this. Remember that you should not stop taking sertraline suddenly, as this can cause withdrawal symptoms.

 - Sertraline passes into breast milk in small amounts and may affect your baby. You should get advice from your doctor if you want to breastfeed while taking sertraline. Various factors need to be taken into consideration, for example whether you were taking sertraline during the pregnancy and if the baby was born prematurely. In some cases it's OK to breastfeed while continuing to take sertraline, as long as the baby is monitored for any potential problems. Always get advice from your doctor.
 What are the possible side effects of sertraline?
 Medicines and their possible side effects can affect individual people in different ways. The following are some of the side effects that are known to be associated with sertraline. Just

James City County is one of the fastest-growing places in Virginia, according to the 2020 census. However, the expansion is far from uniform across the county. Last week, the Board of Supervisors supported a redistricting plan to respond to the growth pressures.
The supervisors mooted other potential changes to the future of elections in the county including reducing the number of precincts due to the rise in early voting and a move away from polling stations in schools in favor of churches.
A report to the county from Assistant County Administrator Jason Purse and Elizabeth Parman, assistant county attorney, highlighted the growth pressures the county faces.
The report noted that the county's population increased from 67,009 in 2010 to 78,254 in 2020, an increase of 17%.
"In comparison, Virginia grew by 8% and Hampton Roads grew by 5% between 2010 and 2020. James City County is the eighth fastest-growing locality in Virginia. 2020 Census data reflect an overall increase in population across all districts; however, the percent increase was not even across districts," the report noted.
"Stonehouse is now the largest district with a total population of 17,770, a 35% increase in population from 2010," the report stated. "Roberts is the smallest district with a total population of 14,414, a 5% increase in population from 2010. The Berkeley and Jamestown districts each grew by 18%, on pace with the County as a whole, while the Powhatan district grew by 9%."
Virginia law requires local districts have similar populations, resulting in the need for a redistricting, the report stated. However, the rapid growth in Stonehouse means the county's largest district is now 23% bigger than its smallest. Stonehouse is the most northerly district in the county, abutting the York River.
Purse and Parman presented two redistricting plans for the board to consider Sep. 28. Option one entailed the moving of 3,403 people across districts, about 4% of the total population
"In this map, an area with 1,723 people north of Route 60 and southwest of Highway 30 moves from Stonehouse to Powhatan. This area includes Skillman Estates, The Retreat, Meadow Lake and Racefield," the report stated.
"A second area with 218 people east of Little Creek Dam Road, Little Creek and Yarmouth Creek moves from Stonehouse to Powhatan. A third area with 501 people north of John Tyler Highway and Brick Bat Road and south of Bush Neck Road and Jolly Pond Road moves from Powhatan to Berkeley. A fourth area with 961 people east of Jamestown Road and including Jamestown Island moves from Berkeley to Roberts. This area includes Powhatan Shores, Landfall at Jamestown, Raleigh Square, and the Cottages at Stone Haven."
The second option entailed the removal of 9,305 people across districts — roughly 12% of the total population in a more complicated redistricting. The board voted unanimously for county staff to proceed with the first option.
"This is a first step," Parman said. "We are asking that the board has a look at these maps and considers reaching a district-level consensus."
Supervisor Jim Icenhour said redistricting is a common occurrence in the county.
"I have been here 26 years. I have lived in the same spot and been in three districts. It happens a lot," he said.
Icenhour said the board should consider reducing the number of precincts. He said four districts have four precincts and one has three. "Quite a few of us have very small precincts." He asked if the rise in early voting could allow three precincts across the board.
"It would be tremendous savings in expense," he said.
Parman said the request would have to go to the Virginia attorney general.
Supervisor Ruth Larson said she has raised safety concerns about schools being used as polling stations in the past and suggested churches be considered as an alternative.
"Are we going to look at other options besides using schools?" she asked.
Purse said the county has been working closely with Director of Elections and General Registrar Dianna Moorman over potential changes to the voting system.
"She's very interested in working with us about and trying to figure out if we can identify new places, better places and trying to figure out where that central voting place should be, whether we should keep it at the Rec Center," Purse said.
Supervisor John McGlennon said the first option was "significantly superior" to the second. The other supervisors agreed.

Ready, Steady, Practise! at
Thatcham Park Primary School
Mrs Sheen's Year 5 lesson for multiplying and dividing by 10, 100 and 1000 using the Ready, Steady, Practise! Mental Arithmetic pupil books.
After Mrs Sheen models the concept on the place value grid, the children return to their desks and - depending on how confident they feel - pick which activity they'd like to try from the differentiated exercises in Ready, Steady, Practise!"As a school we try to encourage the children to choose their own activity – this stretches them, as if they feel confident they can go for a more difficult exercise."
Using the books
The children work on their exercises, comparing with their neighbours and getting help from Mrs Sheen or her Teaching Assistant. They then choose a new harder or easier exercise depending on how they're getting along."It makes it easier to have ready to use exercises for the lessons. We often use the books in intervention groups too. They're easy to work from and the children seem to really enjoy using them."
Mrs Sheen puts the answers at the front of the class so the children can mark their own work. The children huddle around and compare marks, then write down how they feel about the exercise.
"We encourage the children to asses themselves and decide whether they've understood the concept or need more help."


Fungi, Quelbe, Scratch – the VI's old-time music
I love the sweet, sassy, and infectious sound of this unique island music.
This weekend, Nov. 18-19, is the fifth annual Fungi Fest in the BVI. I am a bone fide fungi fiend, so in honor of the upcoming event I am sharing the following from Moon Virgin Islands.
An artist's illustration of a quelbe, or fungi, band. Artwork was used by the Reichold Center on St. Thomas to promote a quelbe extravaganza it produced in 2009.
"The traditional music form of the Virgin Islands is quelbe music, also called scratch or fungi. A quelbe band consists of a banjo, conga drum, squash, and a triangle. Other instruments sometimes include guitar, bass, saxophone, or flute. Quelbe musicians use objects close at hand to construct their instruments, although today some have adopted more modern instruments. The banjo was often made out of an old sardine can. The squash was a dried local gourd, serrated and then scratched with a comb or wire-pronged stick. The base line was usually provided by someone blowing into the discarded tailpipe from a car.
"Quelbe music developed on sugar plantations, where slaves used materials at hand to provide a rhythm and melody to which they could tell stories, share jokes, and spread gossip. The music was influenced by African rhythms and the sound of Danish and British military bands. After slavery ended, quelbe music grew in popularity as the restrictions of slavery ended and the music form could spread freely. Many older Virgin Islanders have sweet memories of nights spent dancing to the sound of their village quelbe band.
"Quelbe music still tells stories and jokes, often with a risque undertone. Quelbe is especially popular at Christmastime, giving a new and refreshing take on Christmas music. Traditionally, quelbe bands would go serenading in the wee hours of Christmas morning, wishing their neighbors a merry Christmas.
"Today, quelbe music is being preserved by a handful of bands. In the British Virgin Islands, the Lashing Dogs and Loverboys perform fungi music (as it is called there) at bars and festivals. In the U.S. Virgin Islands, Jamesie and the Allstars, Stanley the Ten Sleepless Nights, Bully and the Kafooners, and Blinky and the Roadmasters carry on the tradition. Jamesie Brewster, the leader of Jamesie and the Allstars, is the subject of a forthcoming documentary. You can hear a snippet of his music at
"The traditional accompaniment to quelbe music is the quadrille, a kind of square dancing introduced to the Virgin Islands from the French Caribbean and influenced by English and Irish planters. Quadrille or not, it is impossible to stand still listening to quelbe music. St. Croix culture bearer and writer Richard Schrader wrote in his book Maufe, Quelbe and t'ing that when Jamesie Brewster performs, "trees shake their branches and grass bends down low." That just about sums it up."
BVI Fungi Fest takes place at the Noel Lloyd Positive Action Movement Park in Road Town on Friday, 18 November and Saturday, 19 November. Music begins at 7 p.m. each night. Performers will include The Jolly Boys from St. Martin, the Ole Time Jammers from Tobago, the Quelbe Ambassadors of St. Croix, Flambo Combo of St. Thomas, Koko and the Sunshine Band of St. John. Also performing are the BVI's own Serenaders, Leon and the Hot Shots, Razors Blades, Lashing Dogs and the gospel fungi band, Zion Sounds.

Income Tax Assessment Act 1997
The object of this section is to ensure that the *tax free component and *taxable component of a *superannuation benefit are calculated by:
(a) first, determining the proportions of the *value of the *superannuation interest that those components represent; and
(b) next, applying those proportions to the benefit. 307-125(2)
The *superannuation benefit is taken to be paid in a way such that each of those components of the benefit bears the same proportion to the amount of the benefit that the corresponding component of the *superannuation interest bears to the *value of the superannuation interest.
The amount of a superannuation lump sum is $100. Just before the benefit is paid, the value of the superannuation interest was $1000 (of which $200 was the tax free component and $800 was the taxable component). For the lump sum, the tax free component is $20 and the taxable component is $80.
For the purposes of subsection (2), determine the *value of the *superannuation interest, and the amount of each of those components of the interest, at whichever of the following times is applicable:
(a) if the *superannuation benefit is a *superannuation income stream benefit - when the relevant *superannuation income stream commenced;
(b) if the superannuation benefit is a *superannuation lump sum - just before the benefit is paid;
(c) despite paragraphs (a) and (b), if the superannuation benefit arises from the commutation of a superannuation income stream:
(i) if subparagraph (ii) does not apply - when the relevant superannuation income stream commenced; or
(ii) if the superannuation income stream is a *deferred superannuation income stream that had not commenced before the time the commutation happened - just before the time the commutation happened;
(d) despite paragraphs (a) and (b), if:
(i) the superannuation benefit is an *involuntary roll-over superannuation benefit paid from a superannuation interest; and
when that superannuation income stream commenced.
(ii) that interest was supporting a superannuation income stream immediately before that benefit was paid;
Subsection (2) does not apply to a *superannuation benefit if any of the following applies:
(a) the regulations specify an alternative method for determining those components of the benefit;
(b) a determination under subsection (5) specifies an alternative method for determining those components of the benefit;
(c) the Commissioner consents in writing to the use of another method for determining those components of the benefit.
If so, use that method to determine those components of the benefit.307-125(5)
For the purposes of paragraph (4)(b), the Commissioner may determine, by legislative instrument, one or more alternative methods for determining those components of a *superannuation benefit. 307-125(6)
If the *superannuation benefit is an *unclaimed money payment or a *small superannuation account payment, for the purposes of this section:
(a) treat the benefit as a superannuation benefit paid from a *superannuation interest; and
(b) treat the amount of the benefit as the *value of that superannuation interest just before the time the benefit is paid.

well with as little as $1,800. The problem with these wells is that they are easily contaminated and last for a few years before drying.
Sandpoint well
Sandpoint wells are the perfect solution to temporary water needs.
It's the most economical option and easy to install. If you have a meager $300, you can build a Sandpoint well to completion.
Sandpoint wells are shallow and narrow. After digging a hole into the ground, insert a 20-foot-long pipe with a two-inch diameter.
The tube has a screen that filters water from the sand, and the pump pushes the water to the surface. You can use the water directly or divert it to a storage tank.
Despite its affordability, a Sandpoint well has little output. It provides an average of three gallons per minute.
Also, it isn't easy to maintain constant water pressure.
Private Well vs. Municipal Water System: Which is Better?
Private well vs municipal water system explained
Private well vs municipal water system
The cost of electricity to run a well pump for a medium household is $10.
In comparison, the average monthly water bill is $70.
Therefore, driving a private well can save you more than $600 yearly. If it's an irrigation well, the savings can be more.
Additionally, most municipalities charge sewer costs in their water bills. If you have a septic system, you don't incur this expense.
As Seen Above – Private wells are more advantageous than municipal water systems. However, they are expensive to install.
Why You Need a Well Drilling Company
It's impossible to tell how deep you need to drill to reach underground water.
This explains why most contractors don't give quotes until they start drilling on the site.
After that, however, they can give a rough estimate based on previous projects in their portfolio.
If the contractor doesn't find water, they'll move to another location. You'll need to cover the cost of drilling both sites.
Before hiring a contractor, check if they have National Ground Water Association certification.
Frequently Asked Questions
Digging well FAQs
Digging a well cost FAQs
How long does a water well last?
With proper maintenance and care, a well should last for at least 35 years.
However, if installed shoddily, the lifespan can be reduced by more than 20 years, notwithstanding the safety risks. On the other hand, well pumps need replacing after ten years.
Can a well dry up?
A well dries when water levels drop below the pump's intake.
You can restore water levels through aquifer recharge or reducing pumping frequency. It's advisable to hire pros to examine water levels.
What is the cost of maintaining a well?
The cost of well maintenance ranges between $150 to $300 yearly.
After inspection and servicing, your contractor will provide a report showing well health and recommendations on keeping your water safe.
How long will it take to drill a water well?
Depending on diameter and depth, ground conditions, and weather, drilling takes one to three days.
Setting up equipment, component installation, and water testing increases the project length to a week.
Wrapping Up
There's no denying that wells are an expensive investment.
However, the high cost of drilling and installing well components is worthwhile, as you'll save hundreds of dollars yearly for many decades once the project is complete.

The simple answer probably doesn't do want you want.
my $str = 'aaaa';
$str =~ s/a/a_/ for 1..2;
print $str, "\n"; # a__aaa. But you want a_a_aa, right?
You need to count the replacements yourself, and act accordingly:
$str = 'aaaa';
my $n = 0;
$str =~ s/(a)/ ++$n > 2? $1 : 'a_' /ge;
print $str, "\n";
See the FAQ, How do I change the Nth occurrence of something? for related examples.
share|improve this answer
Just substitute $n times:
$string =~ s/a/i/ for 1..$n;
This will do it.
More general solution would be global substitution with counter:
my $i = 0; # count the substitutions made
$string =~ s/(a)/ ++$i > $n? $1 : "i" /ge;

If I understand you correctly, you need smth like this: my $i = 0; $str =~ s/(\*)/ ++$i > $n? $1 : "*\n" /ge; – eugene y Jan 29 '10 at 14:50
I'm not aware of any flag that would do that. I'd simply use a loop:
for (my $i = 0; $i < $n; $i++)
 $string =~ s/a/i/;

i beleive this would be more efficient then simply doing $string =~ s/a/i/ for 1..$n; – jojo Jan 29 '10 at 11:36
Please explain why you believe it is more efficient. You unnecessarily create 2 extra temporary variables ($str1 and _USER_). You could simplify it as $str = join 'i', split /a/, $str, $n;, but I don't think that is nearly as easy to understand as the s/// solution. – toolic Jan 29 '10 at 13:33
you may be right about the easy to understand. but as for efficiency using s/a/i/ for 1..$n will take O(n*m). while using split will take O(n). – jojo Jan 29 '10 at 13:39
This also avoids the problem encountered when the replacement string matches the match expression. – Jeff B Jan 29 '10 at 20:27
Here is a way to do based on the comment you made to eugene y's answer
use strict; use warnings;
my $string = '***ab***c';
my $n = 3;
1 while $n -- and $string =~ s/\*([^\n])/*\n$1/;
print "$string\n";

sub substitute_n {
 my $n = shift;
 my $pattern = shift;
 my $replace = shift;
 local $_ = shift;
 my $i = 1;
 s{($pattern)} {
 $i++ <= $n? eval qq{"$replace"} : $1;
You can then write
my $s = "***ab***c";
print "[", substitute_n(2, qr/\*/, '$1\n', $s), "]\n";
to get the following output:

Won't the output actually be: [\n\nabc]? It will match on the first * on each iteration. – Jeff B Jan 29 '10 at 20:25

I Scream, You Scream, ESL Classes Scream for Ice Cream
Are there young people who do not like ice cream? Probably, but for the most part ice cream is a favored treat among young people from all areas of the globe. You can use this natural affinity for the frozen dairy product to liven up your ESL class with some activities centered around the chilly treat! Following are reading, writing, listening and speaking activities that involve the shiveringly good snack, ice cream.
How to Proceed
A Rainbow of Flavors
If your students like ice cream as much as most young people do, this first activity will energize and excite them. Working together as a class or in groups of four to five students, ask your class to brainstorm as many ice cream flavors as they can. They can include flavors for sale in your geographical region as well as ice cream flavors your students may only be able to find in their home countries. Once the list is as long as your class can make it, challenge students to break the list into different categories. Each category should be distinct from every other category, and there should be enough categories so that every flavor is included in one and only one category. Your students may choose to work with fruity flavors, candy flavors, flavors with nothing in them and flavors with things in them (chocolate chips, for example). Allow your students to be creative in their categorizations. Then have them continue to work in groups to define each category and write a short description of that category. Most likely, they will find flavors that do not fit easily into one category or another, or they may find others that may fit into more than one category. If so, have your students note and explain the exceptions to their categorization schemes.
Now that your class has seen what manufactures have to offer, challenge each person to come up with some inventive flavors of his own! If he could make his own ice cream flavor, what would it be? Ask each person to think of at least five new ice cream flavors that he would like to see made available and then make sure each of the flavors has a unique name. Then each person should choose one flavor and present it to the class trying to convince the class that his idea is the best new ice cream flavor possibility. After everyone has presented his new flavors, ask the class to vote for the one new ice cream they would like to see manufactured. If you like, have each person decorate an ice cream scoop template for his original ice cream flavor and then display those scoops stacked on one another on the wall. Make a simple brown paper triangle to place under the scoops to look like an ice-cream cone, and make sure the winning flavor gets the top position on the cone.
Almost everyone has some memories associated with ice cream. One could be licking an ice-cream cone while walking through a local fair or a large amusement park. Another could be making a gutter sundae with a large group of young people. Still another might be making zip lock bag ice cream in a preschool class. Ask your students to share some memories they have that include or involve ice cream. Do your students have good memories? Do they have any bad memories? If students cannot think of a memory that includes ice cream, is there some dream that they have that could involve ice cream? Ask your students to write a personal narrative that tells their ice cream story. Before writing the stories, remind your students that each story must have a beginning, middle and end. You may also want to review the story elements of setting (where the story happens), character (who is in the story) and plot (the events of the story). After your students write their stories, encourage volunteers to read their stories to the rest of the class.
A Squishable Fun Time
Your students, after all their talking and writing about ice cream, will probably be ready for a chilly snack! You can give them the opportunity to make their own ice cream in class with a zip-lock ice-cream activity. Not only that, you can also challenge your students' abilities to follow spoken directions as each person makes his chilly treat. Take the zip-lock ice-cream recipe and have all the ingredients and supplies ready for your students. You may want them to work in small groups or individually, so make sure you have enough of each item for your entire class. If you want to test your students' listening comprehension, read the directions for making the ice cream out loud one step at a time and have your students follow those directions. If you prefer to test their reading comprehension, give each person a copy of the recipe and have him follow the directions to make his own ice cream snack. When you are through with the activity, you can have sundae toppings for your students to put on their creations, if you like. Not only will your students have fun following directions, they will be making a new ice cream memory that will last!
Of course, some or all of these activities may not be appropriate for every ESL class.
Allergy awareness is of utmost importance any time you decide to use food in the classroom as some allergic reactions can be deadly. Make sure you know what if any restrictions your students have on their diets and plan your activities accordingly. With that in mind, encourage your students to have fun with this ice cream unit using their creativity and energy!

Avion Solutions, a Huntsville-based company that specializes in aviation and engineering within Army Aviation, recently unveiled their new 50 kilowatt solar array. During the Avion Solutions solar ribbon-cutting ceremony, Randy Buckner, the Director of Research and Development was quick to point out that this was not the first step they've taken to reduce their energy use. Whether you are seeking energy efficiency in a home or a commercial facility, the first steps are in reducing energy use and making the overall facility more energy-efficient. Only after that is complete do you install something like a solar array.
Under Buckner's leadership Avion has taken many steps to cut their energy consumption. When Avion was first entered their data in ENERGY STAR's Portfolio Manager, the company's facilities only received a score of 2 out of 100! Buckner set his sights on changing that and by making just simple small changes within the building they were able to increase their score to 54.
Buckner said the first step was awareness. Knowing the tools they had available and how to use them properly was the first step. Utilizing the software that came with their HVAC system, Buckner was able to optimize the system, and determine that a few small upgrades would mean big payoff.
Heating and cooling was responsible for 54% of Avion's energy use. Using the tools they already had available, Buckner discovered that they were cooling already cold air in the winter. The HVAC system was running constantly. Optimizing the system use netted Avion a 41.3% energy savings.
The next step was upgrading the outdoor lighting to LED. This simple retrofit saved Avion another 11.6% on their energy bills.
Avion's most recent (and largest) energy improvement was the installation of a revenue-generating photovoltaic system. They sell all their energy directly TVA under their Green Power Providers program at a 40% profit margin from the going retail rate (~$0.10/kWh). This agreement will provide Avion with a net profit of over $111,000 over the course of 20 years.
But, they aren't finished yet! Avion still has more plans to improve their energy efficiency with the goal of 'Net Zero Energy'! They are partnered with Energy Alabama in our North Alabama Buildings Performance Challenge to help other companies int the Huntsville/Madison County area reduce their energy usage too.
Buckner continues to work on awareness among the companies employees, showing them how small changes within their individual offices can net big payoffs. Where employees used to use space heaters to keep their office warm in the winter they are finding that they can now stay warm without it.
Avion already has automated lighting systems throughout the building, but Buckner has found that a small change in how those lights are set up could provide even more savings, while allowing individual employees more control over the level of lighting in their offices.
Avion has also placed an advanced order for a Tesla Power Wall which will use stored power to assist in reducing their overall usage during peak times. They also have plans to install electric car charging stations that will be available to Avion employees, customers, and neighbors.
This is obviously just the beginning for Avion as they lead the charge towards bringing Huntsville businesses to 'Net Zero Energy'.

During the last two or three decades, incidence of failure of reinforced concrete structures has been seen widely for many reasons, such as increasing service loads and/or durability problems and the economic losses due to such failures are costly. Nowadays, the size and the form of repair and rehabilitation market are too large since there has been an increased emphasis on repair and retrofitting of defected structures over demolition and new construction. For safety in concrete tunnel, periodic inspection has been conducted using many testing technologies and techniques. However, these technologies cannot replace visual inspection because of their slow and complicated procedures. For this reason, the Knowledge-Based Systems (KBS) are used with lab tests results to diagnose R.C tunnel lining corrosion crack damage (DICRCTL). In this study, we attempt to propose an alternative to the human expert, to give technical decisions in diagnosing corrosion crack damages in second segment of R.C. tunnel lining. To overcome this requirement, an expert system is developed to achieve the research aim. This proposed system was constructed on a knowledge base that incorporates with the gathered information, tests in the form of rules which is suitable to implement in an expert system environment to diagnostic advisory nature. The proposed application results show an easy, fast and satisfactory answer to engineering needs.

This is expected behavior, but why isn't always obvious. This is a very important distinction in languages like Ruby. There are three things in play here:
 1. The constant A
 2. The variable b
 3. The hash { :test => '123' }
The first two are both kinds of variables. The third is an object. The difference between variables and objects is crucial. Variables just refer to objects. When you assign the same object to two variables, they both refer to the same object. There was only ever one object created, so when you change it, both variables refer to the changed object.
share|improve this answer
+1 for mentioning references vs. data ("objects"). – Andrew Marshall Apr 10 '12 at 7:13
add comment
This is because of the shallow copy mechanism. In your example A and b are actually references to the same object. To avoid that use:
b = A.dup
This will initialize b with a copy of A instead of pointing it to the same hash(i.e. this uses deep copy).
For more info see here what shallow and deep copy is.

what the best way to draw a step foundation. There a a lot of steep lots where I work and was wondering of a way to draw foundation once in the plan view and when doing elevations the foundation is step to match the existing grade on the lot. Just wonder if easier way Frank
There's a number of ways to tackle this. If you know all the RL's for the steps in the footings then you could do it using the smart parametrics. You would need to first create some 'wall' entities for the footings set at the nominal width then using z-base/z-height to define each horizontal segment before changing at the step. Just like drawing a smart wall except the wall is now a concrete edge beam or footing. You would draw this in plan view altering the z-b/z-h as you change up or down at each step. The main slab(s) can be a covered polyline.
Other options include the same as above but using the older solid primitives - slabs. You could also create the stepped footing using horizontal slabs tracing around the outline of the slab and steps then rotate and position in place on plan. You'd need to do this for each side of the building and piece them together.
Personally, the smart parametric option is perhaps the better way to go as you can also use the entities in your documentation knowing the sections will update if you change the plan etc.

Water Chlorination to Begin
The City of Lodi will start temporary chlorination of the Cityís drinking water system on Saturday morning, January 10, 2004. The chlorination is tentatively planned to last for about three weeks.
The chlorination is being done as a precautionary measure and is recommended by the State Health Department Ė Stockton Office. The chlorine will be applied at less than one part per million.
The chlorination is due to positive total coliform bacterial samples over the past week (there were NO fecal coliform positives). The number of positives samples is not a violation of drinking water standards. Additional follow-up tests and evaluations are also being performed.
Lodiís water is normally not chlorinated. The chlorinated water may have a strange smell or taste for a few days, but Lodiís water will remain safe to drink. The chlorination may make the water taste or smell slightly like bleach.
Anyone operating dialysis machines will have to dechlorinate the water before using it in the machines.
Do not use chlorinated water in fish tanks, aquariums or ponds unless you dechlorinate the water first! Fish basically breathe the water and the chlorine can cause them to suffocate. Most local pet shops with aquarium supplies sell dechlorinating agents.
Normally much of the chlorine will dissipate from water if it is set out overnight in a shallow pan. Also, boiling the water for a few minutes will drive off much of the chlorine.
Some industries may also have to take precautions while the Cityís water is being chlorinated in case the chlorine in the water may interfere with their operation.
If there are any questions about the chlorination or regarding Lodiís drinking water, please contact Assistant Water/Wastewater Superintendent Frank Beeler at _PHONE_.

MTU Onsite Energy case study: Hutterite Colony depends on standby power for high-tech operations
When utility power fails, the new MTU Onsite Energy generator ensures continuous power for all of the colony's agricultural and woodworking equipment.
Winnipeg, Canada – The Springfield Colony, one of 105 rural Hutterite communities located throughout Manitoba, is home to 113 men, women and children as well as the agricultural and manufacturing activities that support the community. The colony farms more than 6,000 acres, manages a 600-sow hog operation, keeps 8,500 laying hens and raises more than 20,000 broilers every eight weeks. In addition, Springfield Colony is noted for high-quality woodworking—cabinets, countertops, doors and office furniture—that it sells to customers in Manitoba and northern Ontario. All of these activities are critical to the colony and require dependable standby electric power generation in the event of utility power failures.
When Springfield Colony's electrical loads outgrew its old standby generator, the colony turned to a higher-capacity unit from Katolight by MTU Onsite Energy. Besides meeting all of the colony's current power needs during an outage, the new generator set and accompanying control equipment have helped make seamless transitions from utility power to standby generator power.
Why standby power is important
Far from a luxury, standby power provides a critical lifeline for manufacturing and livestock production as well as the day-to-day livelihood of the colony members. The potential for loss of life and productivity is high, particularly in the hog barn where electricity keeps the ventilation fans running. Without electric power, "hogs would start suffocating within half an hour," says James Kleinsasser, the colony's electrician. "We could lose millions of dollars in just one hour."
Standby power is also critical for the colony's high-tech manufacturing operation (the colony's main power user), which includes computerized equipment such as electric saws, milling machines and a paint booth. Other agricultural processes that depend on electricity include the feed mill and the grain-handling system.
Normally, electricity is provided by the local utility. There are times, though, when utility power isn't available. The colony experiences frequent power outages and once lost power for 17 hours, reports Kleinsasser. For a long time, the colony relied on a 400 kW standby generator to keep the manufacturing and agricultural equipment running. But as the colony's manufacturing operation grew, the old generator was no longer able to supply all of the colony's electrical loads when the utility failed.
The standby power shortage was magnified when the colony changed its dairy operation into a cabinet manufacturing facility. Without enough power to go around during utility outages, "we had to limit the load," Kleinsasser recalls. At such times, for example, no power would be available for grinding feed for the barns.
New generator upgrades standby system
Rather than live with this situation, the colony eventually decided to replace the old generator with a higher-output unit. After considering a number of possible replacements, Kleinsasser selected a Series 2000 generator from MTU Onsite Energy. Powered by a 12-cylinder MTU diesel engine, the Series 2000 generator has a rated capacity of 750 kW, which is more than enough to keep electricity flowing to all of the colony's equipment and homes during a utility power outage.
To facilitate the operation of the genset, the colony also purchased MTU Onsite Energy's digital genset controller. Reliable, cost effective and easy to use, this unit features advanced microprocessor technology that controls both the generator and the transfer switch.
The generator set and controller were supplied by Manitoba-based PalmLite, the local MTU Onsite Energy distributor that provides equipment and services for agricultural, industrial and residential applications. PalmLite also helped with the generator startup and worked with the factory's engineers on programming the controller.

text: A recent overview of Salvinia finds from archaeobotanical literature by Out (2010), which also includes the finds in the present study, shows that Schokkerhaven is the most northern location of mid-Holocene Salvinia finds. It is the only location outside the Rhine/Meuse river area. Formerly, finds of Salvinia were dated to the Atlantic (early-Neolithic) mainly based on Zandstra (1966). The overview by Out provides more finds that are dated in the transition from Atlantic to Sub-Boreal and shows the occurrence of Salvinia during the Sub-Boreal (late-Neolithic) period. This fits with the occurrence of an other thermophilous aquatic species, namely Trapa natans elsewhere in the Netherlands. Trapa was frequently recorded in the early Subboreal (archaeobotanical database RADAR; Van Haaster & Brinkkemper 1995; Behre 1970).

Awards & Honors: 2000 National Humanities Medalist
Herman T. Guerrero
Herman T. Guerrero's nickname, "Jun Pan," tells a piece of his family history and a small piece of the history of the Northern Mariana Islands as well. He inherited the name from his father, who was interned in the islands by the Americans at the beginning of World War II. His father was pressed into service as a baker for the native prisoners at Camp Susupe; he proved so successful that the military asked him to stay on as the islands' civilian baker after the war. He was called Pan, or "Bread," and his son proudly bears the name of Jun Pan, "Bread Junior."
Guerrero is working to reclaim the islands' colonial history and the legacy of the native Chamorro people, who were nearly wiped out by Spanish colonists in the seventeenth century. He serves on the board of directors of several companies, including his family bakery, and has worked on the CNMI (Commonwealth of the Northern Mariana Islands) Humanities Council since 1992.
One of his and the council's efforts is the Genealogy Project, which is being conducted with the help of the University of Guam's Micronesian Area Research Center. Guerrero sees "a tremendous growth in native islanders' interests in tracing their ancestral roots."
He also helped create "Spain in the Marianas: First Contact and Aftermath" with the Northern Mariana Islands Museum of History, as well as displays on linguistics, religion, and cross-culturalism.
In the course of four hundred years, the islands passed from Spanish to German to Japanese rule, becoming an U.S. territory in 1947. In 1978 they became a Commonwealth, and in 1985 islanders were granted partial U.S. citizenship. Over the same stretch of time, the islands moved from the era of galleon trade to the nuclear age.
Guerrero's personal history reflects some of the complexity of the islands. He went to high school in Saipan and Guam, received a B.A. in Sociology from St. John's University in Minnesota, and did graduate work at the University of South Florida. He has served as a Representative in the Northern Marianas Commonwealth Legislature, and has worked in the CNMI Office of the Governor and in the Department of Education.
In all of his projects, Guerrero seeks social cohesiveness by documenting the past and promoting discussion for a population that has culture, language, and generation gaps left from its colonial past. An exhibition on the islands' Japanese era is on display at the CNMI Museum until July 2001, and Guerrero is working with the Diocese of Chalan Kanoa to obtain the oldest records of the Chamorran people. He is also promoting a museum exhibition on the U.S. portion of the islands' administrative history.
As he sees it, "The humanities and humanities education allows the indigenous people of the Northern Mariana Islands Archipelago a rediscovery and an affirmation of their native identity. It also allows them the wherewithal to tackle the modern day challenges that they face as they continue to forge their way within the political, economic, and social spheres of an increasingly global community."

According to the OIG report released today, Angela Williamson, a deputy to Monica Goodling at the DOJ, was intimately involved in her bosses scurrilous hiring practices, attending interviews and often conducting interviews herself. Here's a sampling of the same questions that Goodling asked those being considered for political positions:
After Goodling resigned, Williamson typed from memory the list of questions Goodling asked as a guide for future interviews. Among other questions, the list included the following:
Tell us about your political philosophy. There are different groups of conservatives, by way of example: Social Conservative, Fiscal Conservative, Law & Order Republican.
[W]hat is it about George W. Bush that makes you want to serve him?
Aside from the President, give us an example of someone currently or recently in public service who you admire.
We found that this last question often took the form of asking the candidate to identify his or her most admired President, Supreme Court Justice, or legislator. Some candidates were asked to identify a person for all three categories. Williamson told us that sometimes Goodling asked candidates: "Why are you a Republican?" [emphasis ours]

Our Scopolamine Main Article provides a comprehensive look at the who, what, when and how of Scopolamine
Definition of Scopolamine
Scopolamine: A naturally occurring member of a large chemical class of compounds called alkaloids. Scopolamine was first introduced into medical usage in 1902. The name comes from that of the 18th-century Italian naturalist Giovanni Scopoli.
Scopolamine and atropine, comes from the plant Atropa belladonna also called "deadly nightshade." It was once used by the Spanish ladies to dilate their pupils and make their cheeks rosy. It has also been used as a poison. When scopolamine is given in lower (non-poisonous) doses, it causes "mad as a hatter, dry as a beet, hot as a hen" hallucinations, fever, flushed skin and cardiac arrhythmias. The jimson weed seeds are sometimes used for this sense of euphoria (a "high").
Scopolamine together with morphine provided childbirth without pain (or without the memory of pain), once a much sought-after objective. Known as twilight sleep, this combination of drugs could cause serious problems. It completely removed the mother from the birth experience and it gravely depressed the baby's central nervous system. This sometimes made for a drowsy depressed baby with depressed breathing capacity. Twilight sleep therefore has fallen entirely out of favor and is now a chapter in the history of obstetrics.

Should I Use Beneficial Bacteria Pond Products In The Winter?
Woodrow - Burlington, WI
Most people assume bacteria are a bad thing since they've spent most of their lives learning to avoid it. However, bacteria can be extremely beneficial to outdoor ponds, and are even recommended for a healthy and stable pond environment. But what exactly are we referring to when we say "bacteria?"
These helpful bacteria are called aerobic bacteria, and are used to consume organic waste, turning it into an odorless gas which escapes from the pond unnoticed. They are found in both PondClear™ and MuckAway™, which aid in keeping pond water healthy, clear of debris, and fresh smelling.
Products that contain aerobic bacteria work best at temperatures above 50 degrees, which is why you would want to stop adding bacteria during the winter months. In temperatures below 50 degrees, bacteria are not as efficient and therefore are not recommended for use. So save that bacteria for warmer days, and you'll have a healthy pond clear of unsightly muck and debris.
Pond Talk: Have you seen a reduction in muck using natural bacteria over the summer months?

Why are three symbols censored by Microsoft Windows and Office?
There are three symbols that Microsoft won't put in their fonts for Windows and Office. They are obscure and you're unlikely to need them. It's an interesting bit of trivia and example of the differing corporate cultures and judgements.
(This article includes an image that might offend some people. NSFW, as they say).
There's a font in Windows that has Egyptian hieroglyphs, no kidding. It's called Segoe UI Historic and has many other scripts including Coptic, Glagolitic, Gothic, Meroitic Cursive, Ogham, Old Italic, and Runic.
Starting at Unicode position 13000 are Egyptian hieroglyphs, which are just part of the enormous Unicode character set.
Typing a hieroglyph is simple once you know the Unicode hex value. In Word type 13080 then press Alt + X, in modern Word you'll get the famous Eye of Horus. Word will switch to Segoe UI Historic because it's a font which has that character.
See Word's symbol substitution, the good and the bad and Try the old Alt + X trick for Word and Outlook
But try that with Unicode 130B8, 130B9 or 130BA you'll get a black rectangle. Exactly the sort of symbol that we used to see in Word too often but has largely been eliminated.
What's going on?
It seems Microsoft is a little squeamish, puritanical, or at least, wary of controversy. They removed three phallic hieroglyphs that are part of the Unicode standard.
Apple is OK with it
Apple macOS doesn't have the same limitation. In the Character Viewer (Ctrl + Command + Space) and search for 'Egypt' shows all the available hieroglyphs including the "phallic three".
