Mining Initiative (GMT), launched in 2009, brings together stakeholders to develop green technologies, processes and knowledge for sustainable mining. The GMI objectives are to improve the mining sector's environmental performance, promote mining innovation and position Canadian mining companies and suppliers as global leaders in green mining in an emerging market. Natural Resources Canada invests $8M annually on the GMI with an additional $3M in direct industry funding. The Green Mining Initiative has spurred green mining innovation across Canada, which led to significant progresses on a number of key R&D projects and new projects being launched. Examples include developing and testing, in collaboration with a Canadian equipment manufacturer, the first worldwide electric-diesel hybrid loader in a Canadian mine. Additional funding from Sustainable Development Technology Canada will result in the bringing to market of a new hybrid loader with over twice the production capacity of the first prototype. A green mining vehicle? green energy roadmap is being developed to provide a strategy for selecting clean alternatives to diesel. Meeting strength requirements for a unique alternative binder process that could be used for mining backfill was also undertaken. Patenting is underway for this technology as well as for a technology developed to successfully recover gold without the use of cyanide. Results of a third year of monitoring on mine sites as part of the Green Mines Green Energy initiative continue to demonstrate that the growth of biomass crops on mine tailings is feasible. GMI is a striking example of good governance in sustainable mining and of what can be achieved throughout collaboration and partnerships. Benefits of increasing collaboration at the international level could be significant.
Canada's Integrated Oceans Management Program (IOM) supports regional processes through which decisions are made for the sustainable use, development and protection of Canada's marine ecosystem and resources. The IOM program provides federal, provincial and territorial authorities, industry and Canadians with the science and risk-based tools and governance fora needed to collaboratively develop Integrated Management Plans for defined ocean spaces. These plans, which incorporate social, economic and environmental considerations in decision making, are informed by the identification of Ecologically and Biologically Significant Areas; Species and Community properties; the mapping of human uses; and the assessment of potential interactions between uses and key functional and structural aspects of marine ecosystems. Outcomes of the IOM process also include the identification of conservation measures, including networks of marine protected areas needed to support the sustainable development of ocean resources contributing to Canada's
continuing fulfillment of international ocean-related commitments.
Sustainable Consumption and Production
Significant Canadian advancement in green building and sustainable community planning has been accelerated, in part, by federal programs such as the EQuilibriumTM Sustainable Housing Demonstration Initiative. Led by the Canada Mortgage and Housing Corporation (CMHC) and supported by Natural Resources Canada's Canmet ENERGY expertise, this initiative will result in the design, construction and demonstration of 12 highly sustainable homes across the country which
produce as much energy as they consume on an annual basis. This cooperation between the public and private sectors has informed, inspired and accelerated the adoption of net zero energy healthy housing concepts nationally. Building on this successful initiative, the $4.2M EQuilibrium TM Communities initiative supports research, monitoring and showcasing of selected high performance neighbourhood projects. EQuilibrium TM Communities aims to provide measurable improvements over current practices in energy and water consumption, environmental protection, financial
viability, land use and transportation.
Canada has put in place a strategy for the environmentally sound and secure disposal of all of its surplus electronic and electrical equipment. The Federal E-waste Disposal Strategy emphasizes reuse prior to recycling, where possible. Reuse options include donation to Computers for Schools (CFS), interdepartmental transfer, charitable donation and sale to the public. The Strategy provides recycling options for equipment that cannot be reused including disposal through provincial
recycling programs and a standing offer for e-waste recycling services. The Strategy is contributing to the realization of the green economy in Canada by creating green jobs, diverting e-waste from landfill, supporting provincial recycling infrastructure and providing computer-based educational and learning opportunities.
Technology Roadmaps (TRMs) are effective tools to enhance the coordination and development of innovative industries and technologies, with benefits to sustainability and the green economy. Since 2002, Canada has used TRMs as forecasting tools that aim to determine future market needs, promote collaboration, and advance promising technologies. TRM processes allow government, industry and academia to work together to predict needs. Many TRMs focus on advancing emerging renewable and clean energy industries, or to address sustainability issues of other industrial sectors.
Industry Canada and Natural Resources Canada have completed TRMs for sustainable fuels and chemicals from biomass, hydrogen fuel cell commercialization, clean coal, and carbon capture and storage. Work continues on TRMs for marine energy and sustainable housing.
Among Canada's newer initiatives are green patents, or patent applications related to environmental technologies. Accelerating such patent applications can foster investment and expedite commercialization of technologies that could help to resolve or mitigate environmental impacts or to conserve the natural environment and resources. In 2011, the Canadian Intellectual Property Office implemented a new regulation to expedite the examination of green patents, and no
fee is required.
Annex II - Proposed Green Growth / Green Economy Indicators
As part of Canada's commitment to further dialogue and identify a balanced approach to measuring progress towards green growth, Canada believes there would be value in an international discussion on a suite of green growth indicators that countries could voluntarily choose to compile. In support of a constructive discussion at Rio+20, Canada is in favour of a process for the creation of a voluntary set of indicators. In this spirit, Canada has identified an illustrative set of indicators for international consideration building upon the OECD's ongoing work on green growth. Using the
OECD's Towards Green Growth framework as a lens, Canada's draft indicators have been groupedby the themes identified by the OECD. The policy rationale for the indicators selected in each theme is summarized below:
I. Environmental and resource productivity Indicators in this theme reflect the need for natural capital to be used efficiently. Sustainable growth will require the decoupling of economic growth and environmental impacts.
II. Natural asset base
Indicators in this theme reflect that traditional markets and accounting frameworks do not always properly reflect the risks associated with declining natural capital stocks. Further, longer-term economic prosperity requires an adequate asset base.
III. Environmental quality of life
Indicators in this theme reflect that environmental considerations can be particularly important to people when they have a direct impact on their lives. Indicators in this theme can be an effective bridge across the economic, social, and environmental pillars of sustainable development.
IV. Economic opportunities and policy responses
Indicators in this theme reflect that policies can help shape and define new opportunities.
Innovative markets and technologies can spur productivity and job growth while minimizing the
environmental footprint of goods and services. Work is required to ensure that the proposed indicators can overcome challenges in data, methodology, and comparability across countries. Canada looks forward to continuing to collaborate closely with the UN, the OECD, member countries, and other partners to further develop this important work.
Proposed green growth indicators
I. Environmental and resource efficiency and productivity
1. Production-based CO2 intensity
2. Demand-based CO2 intensity
3. Energy intensity
4. Share of renewable energy (by type) in total primary energy supply and in electricity production
5. Non-GHG emitting sources as a share of total primary energy supply and in electricity
6. Material intensity
7. Waste intensity
8. Nutrient flows and balances
9. Multi-factor productivity reflecting environmental services
II. Natural asset base
Physical and monetary (where possible) measures of key natural capital stocks:
10. Energy resources
11. Freshwater resources
12. Forest resources
13. Fish resources
14. Mineral resources
15. Land resources (land use and quality)
III. Environmental quality of life
17. Environmentally induced health problems & related costs
18. Population-weighted exposures to air pollution
IV. Economic opportunities and policy responses
19. R&D expenditure of importance to green growth
20. Patents of importance to green growth
21. Environment-related innovation in all sectors
22. Value of environmental goods and services produced in the economy
23. Value-added in environmental goods and services production
24. Imports and exports of environmental goods and services
25. Employment in environmental goods and services production (direct and indirect)
26. Capital and operating expenditures on environmental protection (remediation andmitigation)
Annex III - Institutional Framework for Sustainable Development Proposal
Better Integration of Sustainable Development Considerations in the UN System: a potential Outcome for Rio+20
This is a proposal for the elaboration of a framework that better enables the mainstreaming of sustainable development considerations (i.e., economic, social and environmental considerations) across the UN system, with a particular emphasis on the UN's programming activities at the country level. This approach would include efforts to support developing countries to integrate sustainable development considerations into their national development
plans and priorities as a core element of an enhanced sustainable development partnership.
This proposal is focused on improving existing mechanisms and structures and program delivery at the country level rather than the creation of new institutions and agencies. It is meant to serve as a contribution to the overall effort to improve the institutional framework for sustainable development
This proposal is focused on establishing sustainable development as a mainstream priority within UN programming in developing countries. As such, it seeks to address a gap in the context of the institutional framework for sustainable development, which includes efforts at strengthening sustainable development at the local, national, regional and international levels.
To achieve the integration of sustainable development considerations, a two-pronged approach could be adopted.
At the Country Level:
The first element is inspired by the Delivering as One initiative as an example of how to achieve greater coherence and coordination among UN activities at the country level.
UN programming within the Delivering as One framework is

Laparoscopic Pelvic Floor Repair
What is laparoscopic pelvic floor repair?
Laparoscopic pelvic floor repair refers to the use of laparoscopic or minimally invasive surgery for correction of pelvic organ prolapse.
How does laparoscopic pelvic floor repair work?
Over the last decade, doctors have used laparoscopic surgery for diagnosis and treatment of most gynaecological conditions. In the process, doctors have discovered that laparoscopy can help identify and repair many different defects which cause pelvic organ prolapse, restoring them to normal positions.
How is laparoscopic pelvic floor repair different from other surgical alternatives?
In traditional repair surgery, incisions are made through the vaginal skins and the torn or damaged connective tissues is plicated using absorbable suture materials. In laparoscopic pelvic floor repair, surgeons reattach the prolapsed pelvic organs to the pelvic floor muscles or bony landmarks using non-absorbable / permanent suture or mesh materials. The repair is based on the concept that pelvic organs prolapse mainly as a result shearing forces which damage the connective tissues that attach the pelvic organs to the pelvic floor.
What types of pelvic organ prolapse are laparoscopic pelvic floor repair suitable for?
Laparoscopic surgery is suitable for correction of detachment types of pelvic floor defects which form cystocoele, rectocoele, uterine and post-hysterectomy vault prolapse.
What are the benefits of laparoscopic pelvic floor repair?
The benefits of laparoscopic pelvic floor repair include high success rates (over 90%), little post-operative pain, reduced risk of painful vaginal scars and vaginal strictures.
What are the risks of laparoscopic pelvic floor repair?
Risks associated with laparoscopic pelvic floor repair are uncommon. They include risks associated anaesthesia, laparoscopic surgery and vaginal repair. The latter may include rare injury to bladder, bowel, blood vessels and nerves of the pelvis.
Is laparoscopic pelvic floor repair right for me?
As every individual patient has different types of pelvic floor defects, different tissue quality, different health status, and different expectations, you should consult with your own specialist to determine if laparoscopic pelvic floor surgery is right for you.
At CARE, our highly experienced surgeons specialize in the management of pelvic organ prolapse. We have treated thousands of women, many of whom have been referred due to the complexity of their problems or previous unsuccessful surgical repairs.
CARE surgeons are particularly skilled in the laparoscopic pelvic floor repair and sacro-colpopexy and have taught and demonstrated these techniques at many national and international meetings.

UCLA's Pediatric Cancer Predisposition Clinic offers enhanced care to children with hereditary cancer
download the newsletter
UCLA Pediatric Cancer Predisposition ClinicMore than 12,500 children and adolescents under the age of 20 are diagnosed with cancer each year in the United States. New research suggests that as many as 30 percent of children with cancer may have genetic mutations that predispose them to developing cancer at a young age.
The UCLA Pediatric Cancer Predisposition Clinic is one of a few centers in the nation that offers advanced exome sequencing technology for clinical testing of children who may have a genetic predisposition to cancer. Because most pediatric cancers are not hereditary, the program focuses on children who have a strong family history of cancer; physical signs that suggest a potential predisposition to cancer (hemihyperplasia, macrocephaly); or have any of about 50 rare genetic syndromes that are associated with pediatric cancer predisposition such as Beckwith-Wiedemann syndrome, neurofibromatosis and Li-Fraumeni syndrome. Our team of geneticists, genetic counselors, pediatric oncologists and social workers provides children and families with state-of-the-art genetic tests, personalized cancer surveillance plans and compassionate psychosocial support.
Genetic testing offers several benefits
Diagnosing a genetic predisposition to cancer benefits children and their families in several ways. Cancer screening can result in earlier detection and improved outcomes. Genetic information enhances patient care by alerting pediatricians to the possible presence of other conditions known to accompany an underlying mutation. An accurate diagnosis can also suggest the presence of additional, often treatable, syndromes known to accompany the primary condition. Genetic information also helps couples plan their families and their future.
Exome sequencing is more efficient and less expensive than other genetic tests
UCLA has been a leader in advanced genetic testing techniques such as whole-exome sequencing, a technically challenging test that involves sequencing the protein-coding portions of a patient's genome. Vastly more efficient than older genetic testing options, exome sequencing allows physicians to determine which mutations might be leading to a patient's cancer using the results of a single blood test. The sequencing technology, which is more convenient and less expensive than sequential testing of individual genes, identifies changes or mutations in all of an individual's genes using bioinformatic tools. Members of our data genomics board, who have conducted more than 200 exome sequencing cases to date, review and interpret the data - which can include 22,000 variations in a single exome - looking for disease-associated mutations. UCLA is the only major medical center in California that
offers an exome sequencing service.
Services offered by the Pediatric Cancer Predisposition Clinic
When a child is referred to the UCLA Pediatric Cancer Predisposition Clinic, genetic counselors and geneticists perform an in-depth family history that includes the birth, developmental and medical histories of the child and any siblings. If there is a strong family history of cancer, the child's parents and other family members may be referred to our adult clinic for screening. Our geneticists also perform a thorough dysmorphology exam to determine if the child has any malformations or other physical findings that could be associated with a genetic syndrome.
With a single blood test, children who exhibit patterns that suggest a genetic predisposition to cancer can receive a genetic diagnosis through whole-exome sequencing. Genetic information helps our oncologists design a personal cancer surveillance program using advanced MRIs, ultrasounds and other tools to find the kinds of tumors the child is at risk for developing. When we diagnose a genetic condition, in addition to providing care for the child, we also help identify other family members who may be at risk for developing the same condition.
Genetic testing for high-risk children
Children with solid tumor cancers of the eye, kidney or liver and those with certain sarcomas or adrenal tumors are more likely to have hereditary cancer and should undergo genetic testing - especially if there is a strong family history of cancer.
"Young people typically don't get these kinds of cancer," says Julian A. Martinez-Agosto, MD, PhD, a pediatric medical geneticist. "If a young person is diagnosed with a solid tumor cancer, there may be a genetic reason for it."
The UCLA Pediatric Cancer Predisposition Clinic provides advanced whole-exome genetic sequencing to children at risk of hereditary cancer. It also offers children and their families excellent psychosocial support and a chance to participate in clinical trials designed to develop effective cancer surveillance programs for the pediatric population.
"Most of the studies about how to prevent cancer from developing involve adults," says UCLA pediatric oncologist Vivian Y. Chang, MD. "We want to learn what are the most effective cancer surveillance programs in children so that we can not only catch cancers early, but hopefully to prevent them altogether one day."

Do you ever have trouble finding the right clothes during winter because you are confused by the warmth in your room? A lot of the times, even if you check the weather App on your phone, it is still hard to always dress in the most comfortable way. If let's say, there is a device that can accurately suggest you how to dress in the morning, many miss-dressed instances can be avoided. TechDesign stumbled over a neat design shared by an awesome fellow maker, Jullen Vanier, who invents an IoT weather clock that can accurately tell users what to wear on any given day.
The delicately designed clock looks just like a common home decoration on the wall, and just like its simple appearance, the components are also nothing complicated. The clock hand is moved by a servo motor and it will point to the suitable type of clothes that users should wear. The clock is simply powered by batteries. If you wonder what is the source of the clock's suggestion, then you need to know that all suggestions are made based on the data gathered by the Particle Photon at forecast.io. These data are the secret behind the clock's function. In order to demonstrate how the clock actually functions in reality, Vanier shared a short video:
(Via Julien Vanier on Youtube)
To give you a peek into other major components of the clock, we will start with the circuit board. Vanier chose a servo from the Particle Maker Kit, and the circuit board has three wires connect to it. Other components include a firmware that installs D0 as the servo pin and the cloud function that Vanier applies to control the position of the servo.
As for the antique-looking clock hand, Vanier derived the pattern from GitHub, and turned it into an actual clock hand through 3D printing. A little trick he did to let the clock hand fit the servo is that he left a notch in the 3D part. In order to beautify and secure the clock, Vanier got himself a shadow box to contain the clock. After a few steps of assembling the shadow box and the clock, the final product becomes the useful and practical technological product and home decoration.
In case you try to figure out how the software powers the clock, here is the secret. Vanier divides it into two parts: a Photon firmware that controls the clock hand, and a hook.io script that processes the data coming from forecast.io. In between the two parts, there is the Particle cloud that helps to connect the firmware with the script. To help you better understand the correlation between different parts of the software, Vanier created a graphic to visualize it:
If you want to learn about the complete project detail, please refer to the project profile on hackster.io. TechDesign plans to continue highlight individual projects shared by fellow makers, so if you have any suggestions, please feel free to share them with us at the comments section.

How are YOU going to celebrate National Peanut Day? Over here at Dish Trip we thought it was only appropriate to celebrate this famous in-flight food... in the air! So for our first ever "Food Flight," we staged a creative culinary competition for the unsuspecting passengers on a recent Southwest flight to Denver, CO.
Four courageous competitors were hand-picked by crew members (and by Southwest Airlines' own Brooks Thomas), and challenged to improvise their own in-flight culinary creation using peanuts — the featured ingredient — along with other food that would normally be found on a typical domestic flight. We also threw in some other bonus ingredients!
Check out the video below. Happy National Peanut Day to all of you who are Nuts about Southwest! And a special thanks to Nikki, Jeannie, and Adam for making this an amazing experience. And to Mandy, for being our muse!
Top-Ten Peanut Facts*
- The peanut is not a nut, but a legume related to beans and lentils.
- There are enough peanuts in one acre to make 30,000 peanut butter sandwiches.
- Two peanut farmers have been elected president of the US: Thomas Jefferson and Jimmy Carter.
- A peanut made it to the moon! Astronaut Allen B. Sheppard brought one with him in 1971.
- Peanuts contribute more than $4 billion to the US economy each year.
- There are four types of peanuts grown in the US: Runner, Virginia, Spanish and Valencia.
- The peanut plant originated in South America.
- A mature peanut plant produces about 40 pods that then grow into peanuts.
- Peanuts have a higher antioxidant capacity than grapes, green tea, tomatoes, spinach, broccoli, carrots and many other foods.
- Peanuts contain over 30 essential nutrients and are naturally cholesterol-free.
Ever wonder where the term "Peanut Gallery" comes from? The term became popular in the late 19th century and referred to the rear or uppermost seats in a theater, which were also the cheapest seats. People seated in such a gallery were able to throw peanuts, a common food at theaters, at those seated below them. It also applied to the first row of seats in a theater, for the occupants of those seats could throw peanuts at the stage, stating their displeasure with the performance.

Spirit Science 11_11 ~ DNA Activation
DNA Activation is a reconnection of your original blueprints for life to a higher frequency, or perhaps a "fuller" frequency. As you live your life, and grow, and have the experiences that you have, you may find yourself opening up to a greater awareness and greater knowing of what things mean all around you.
This awareness is made in the connections between the hearts of everyone. This looks like saying what you mean and meaning what you say. Breathing, staying calm, asking questions, looking at everything thoroughly, doing what you love and loving what you do.
Love is not just an affection of another or a feeling you get, but the awareness of the infinite connection with everything. You are one with everything, so am I for that matter, and being in a space of Love is sharing in the knowing that You and I are One consciousness.

Alopecia UK funds invested: £10,500
Further Alopecia UK funds committed: £3000 for Year 3
When: December 2017
Project type: PhD Studentship
Project Lead: Teontor Simakou
Length of project: 3 years
Research Institute: University of the West of Scotland (UWS)
Condition of interest: Alopecia Areata
Funds being used for: Consumables costs for cell culture, nanokicking experiments, PCR and screening of serum and faecal samples for autoimmune factors.
Overall Aim of the Project:
To treat alopecia areata using a non-chemical technology based on nanovibrations (Nanokicking)
Justification for research project:
UWS propose that in the future stem cell therapies will be key in developing regenerative therapies for many conditions, including those affecting the immune response. This project will study the application of nanoscale mechanical stimulation protocols, called 'Nanokicking' to manipulate the differentiation of cells that have immune function, thus impacting on the resolution of different immune conditions, such as autoimmune disorders, immunodeficiency and vaccine development. 'Nanokicking' has already been successful in the targeted differentiation of Mesenchymal Stem Cells (MSCs) to bone and shows huge potential for bone regeneration and bone disorders. UWS have data to suggest it can play a role in other tissue type development. In addition to providing insight into the immunological mechanisms underpinning human disease, the technology has the potential to provide in vitro models which could be exploited commercially.
Who is leading the project:
The project is being run by research student, Teontor Simakou, who is working as part of an interdisciplinary team of enthusiastic scientists, experts in biology and physics. Teontor has a good knowledge of immunology, immunoassays and molecular biology. Teontor's ambition is to learn how physics can boost biological applications and have a positive impact on global healthcare.
Updates on the project:

Cypress: The Wood Eternal
Cypress: The Wood Eternal
 - Cypress: The Wood Eternal
Published Date
 - published 1941
There is frequently a wide variation of color with one shade
usually predominating in a given locality. For instance, the prevailing
type found in the deep swamps of the St. Johns River is amber, referred
to as yellow cypress, while that growing on the fringe or shallow swamps
of the St. Johns is decidedly darker and possessed of stronger grain. The
typical amber wood of the Apalachicola and other alluvial river swamps
occasionally gradates to dark brown or chocolate and when cut often
presents dark stripes on a lighter background.
Trees that show the dark-red bands of the heavier summerwood,
especially in the lower Mississippi River delta, are known as red cypress.
Wood from the northern regions is referred to as white cypress. In
southern lumber camps, logs that float high are also called "white"
regardless of actual color. In lumber camps along the Atlantic coast,
heavy wood which sinks or floats very low is called "black" while in
Gulf region the term refers more to color than buoyancy. Dark cypress
frequently is no heavier than lighter shades of the wood.
When thoroughly seasoned, cypress wood weight on an average
of about 28 pounds a cubit foot. It is considerably heavier than
redwood, spruce, and most cedars. The specific gravity green cypress
generally varies from about 0.80, or 50 pounds, a cubit foot to 62.35, or
the same weight as water, although it is often much lighter than this.
When dried it is sometimes found as light as cork and is frequently used
for floats on fishing nets.

top 5 snake repellents to buy in 2021
Top 5 snake repellents to buy in 2021
A number of people handle unexpected and unforeseen encounters with snakes well, however, others not so much. In this post, we review the top 5 snake repellents to buy in 2021.
Most snake bites occur when humans tamper or try to move the snakes.
Coming across a dead snake can also be a frightening experience, to avoid such scenarios it is better to be armed with a snake repellent.
Snake repellents together with proper landscape maintenance, will with no doubt help people and snakes coming into contact with each other.
Some repellent use scent whereas others uses sound to create a very uncomfortable environment for these serpents.
Not all snake repellents are of the same composition. If you are looking to avoid encounters with these dangerous serpents, read on this article and find the best snake repellent for your home and gardens.
 1. Ortho Snake B Gon
Use the Ortho Snake B Gon Snake Repellent to prevent snakes entry, nesting, and scavenging. The Ortho Snake B Gon Snake Repellent works by crushing the snake's sense of smell subsequently causing it to no longer smell its prey.
The snake will therefore move onto areas with 'fresher' air. As an added advantage of using the Ortho repellents is its 'no stink' formula therefore you can try them risk-free. It is safe for people, pets, and plants.
The Ortho Snake B Gon Snake Repellent is made from active ingredients like Cinnamon Oil, Geraniol, Castor Oil, Peppermint Oil, Clove Oil.
These oils contain a strong aroma that repels these reptiles. It comes in a plastic shaker bottle which makes for easy dispense.
Directions for use
The first step is to remove the seal under the cap and replace it with the shaker top. Hold the bottle with shaker top pointed headfirst and down.
Next, shake the bottle side-to-side to dispense.
Generously apply to the grass and soil around flowers and other plants ensuring you apply an even amount.
When using on food crops, apply this repellent when no above-ground food produces are present, as well as the blossoms. Repeat application frequently after every 30 days.
It is noteworthy that the aroma at first is very strong during the first day but will gradually diminish. Rain also reduces the smell and weakens the granules as well.
 1. Safer Brand 5951 Snake Shield
Safer Brand Snake Shield is a chemical-free formula and it uses a unique combination of natural oils and sulfur that effectively repels snakes without damaging your grass, pets, or family.
The Snake shield is a granular, scent-based snake repellent made from natural essential oils of cedarwood, clove, and cinnamon.
It has a pleasant smell to humans however this smell is unpleasant to snakes. This pungent odor instantaneously begins to work to protect the treated area.
The Safer Brand 5951 Snake Shield is completely safe around people, pets, and plants.
Snakes are vigilant animals that can smell chemical signals in the atmosphere in order to understand their environment.
These signals can be interpreted by the snake's Jacobsen's organ, and then sent to the brain to help a snake navigate.
The Snake Shield blocks this vital communication and confuses snakes, subsequently causing them to automatically flee the area.
Use Snake Shield around practically on any outdoor area such as house perimeters, yards, flowerbeds, parks, fence lines, and more
Directions for use
Apply the Snake Shield by shaking the granules straight from the bag to create an 8-inch wide fence strip around the specific area.
Ensure to create a nonstop barrier strip with no gaps. The barrier will keep the snakes away for weeks. In case of heavy rain, reapply.
 1. BRISON Pest Control Ultrasonic Repellent
Unlike other snake repellent products, the BRISON Pest Control Ultrasonic Pest Repellent does not use pellets or sprays, it simply uses electricity.
This repeller emits "bionic, electromagnetic, and ultrasonic waves" that distract and confuse snakes and other household pests.
The ultrasonic sounds emitted by this device are imperceptible and safe for people and pets.
BRISON Pest Control Ultrasonic Repellent offers total protection in your home, warehouse, or even the office. It not only guards your home against snakes alone but also other pests including the bats, squirrels, and even rats.
Use this repeller as it uses electromagnetic waves that are highly effective and cover a large area of more than 1000 square feet. For best and lasting effects it is recommended you use continuously for three weeks.
Simply plug the BRISON Pest Control Ultrasonic Repellent into the wall socket and you are ready to go.
Another added advantage of using this repeller is that it is safe for both humans and pets and it is also flame retardant making it environmentally friendly.
 1. Enviro Pro 16003 Snake Scram
Snake Scram is a powerful granular scent-based snake repellent.
Made from natural essential oils of rosemary, cinnamon, clove, cedar, and garlic, plus peanut hulls and sulfur, the smell is very strong but not unfriendly, therefore ensure to seal up the remaining unused product in the container for later storage.
Snake Scram is eco-friendly and therefore can be used around people, plants, and pets. It is so powerful that it begins working immediately to chase the snakes away from the treated area and keep them out.
This repellent will only work when applied every couple of weeks. In case of heavy rain, ensure you re-apply since the granules will be washed away thus reducing its effectiveness.
The bottom line is this product does work really well and is better compared to sprays which do not last at all.
Directions for use
The Enviro Pro 16003 Snake Scram covers an even larger area of 2,100square feet. Ensure you spread it evenly while shaking it directly on to the targeted areas. Reapply again after two weeks and again 30 days after the first treatment.
 1. Snake Defense Natural Snake Repellent
Snake Defense is a liquid scent-based snake repellent made from clove oil, peppermint oil, and other non-chemical, harmless ingredients.
The spray emits a quick punch of intense scent that rapidly scares snakes away but is safe for people and pets.

Pet peeve – use of "literally."
If you don't understand literally vice figuratively, _TAG_ can set you straight. Rule#2 of _TAG_ is everything is literal. AI does exactly as you tell it. That can be annoying from a child or spouse or customer service chatbot. AI doesn't have the contextual preferences of humans – which emotes angst and joy in the uncovering. Given a problem, AI is going to take the tasking literally. For example:
I hooked a neural network up to my Roomba. I wanted it to learn to navigate without bumping into things, so I set up a reward scheme to encourage speed and discourage hitting the bumper sensors. It learnt to drive backwards, because there are no bumpers on the back. – _USER_
This is an interesting concept because the "bugs" that you deal with your computer, your phone, your network, your business are likely a synergy of literal translation. Code knows 0 or 1, and coders get that. The rest of us are swimming in "why the hell is this broken" when the answer is a literal question return.

Macoupin County Courthouse
The first courthouse was built of logs on
property that is now the City Square. Seth
Hodges won the contract for the structure.
The record shows that construction costs
Ten years later, the county had outgrown this 18' x 24' log structure and made plans for a larger one on the same site. The new brick building measured 50' x 50' and - costing roughly $15,000 - was considerably more expensive than the first. The contractors were Harbird Weatherford and Jefferson Weatherford.
Abraham Lincoln frequently represented his clients in this courthouse. In fact, when the State Preservation Agency examined the Courthouse records in the 1990's, they found over 3,000 documents with the signature of A. Lincoln. Those original documents are now in Springfield, but copies are on file in the Macoupin County Courthouse.
The courthouse that Lincoln practiced in no longer stands in the center of town because shortly after the end of the Civil War, in 1867, elected officials decided that the prosperous county needed an even larger structure.
Four prominent citizens were commissioned to erect a new courthouse: A McKim Dubois, George H. Holliday, T.L. Loomis and Isham J. Peebles. They selected E.E. Meyers as architect and determined that the construction not begin until there were sufficient funds in the county treasury.
The court also ordered that a property tax of 50¢ per $100 be assessed in Macoupin County and that the monies be used for county purposes, i.e. a new courthouse.
Bonds totaling $50,000 were issued for ten-year terms and bore interest at 10 percent. By September, over $13,000 had been spent and in October the cornerstone was set in place. The cost escalated dramatically from then on. By January 1869 nearly $500,000 had been spent and building was still not complete. The great dome and roof would cost an additional $125,115. More bonds were issued, and by the time the courthouse was officially completed in 1870, the project had cost a staggering $1,342,226.31. Thus evolved the nickname, the "Million Dollar Courthouse."
Not only was the courthouse an exorbitant expense to the taxpayers, rumors of a scandal involving misused appropriations also tarnished the project. Initially, the blame was laid on Judge Thaddeus Loomis and George H. Holliday, county clerk. Judge Loomis was apparently innocent of any wrongdoing. (We may never know the truth about Mr. Holliday, however, because one night in 1870, he boarded a train out of town and simply disappeared.)
Upon completion, this courthouse became the largest county courthouse in the United States, with the possible exception of one in New York City. It was even larger than the Illinois Statehouse. While the courthouse still serves as the seat of county government, it has also become a showplace that attracts tourists, architects and artists from across the country, as well as overseas.
Despite the scandal and the expense, citizens supported this project with amazing dedication. In 1910, a mere 40 years after the cornerstone had been set in place, the last bond was burned and the debt retired. To mark the occasion, 20,000 people gathered in Carlinville for a memorable two-day celebration on July 20 and 21. At a pre-determined hour, all mine whistles, church bells, alarms and anything else that could make a loud noise raised quite a ruckus. The noise wasn't limited to one mighty blast, however, because history records that athletic contests, balloon rides and even airplane rides gave the citizens plenty to cheer about. A parade of cars that stretched more than a mile also entertained the crowds. That doesn't seem like such a spectacular event today, but it was quiet impressive at a time when so few people owned cars.

Background: Determination of the gonads in men is closely dependent on Sertoli cells differentiation and maturation. Many cases of differences of sex development (DSD) are caused by variations in these processes. The study of the mechanisms underlying these complex conditions is crucial for optimal clinical management and Sertoli cells would be an ideal model for this purpose. Our human Sertoli-like cell model (SLCs) may shed some light on the identification of new genes and common pathways involved in the mechanism of disease in DSD.
Objective and Hypothesis: To explore the transcriptomes of three Sertoli cell models Ntera2 (NT2d1), primary human Sertoli cells (HSerCs) and the new SLCs in order to find significant expression differences and similarities that prove the quality of SLCs as a human Sertoli cell model and highlight new potential genes involved in the development of human Sertoli cells.
Methods: We used RNA-Sequencing to analyze the transcriptome of NT2d1, HSerCs and SLCs. Gene Ontology (GO) enrichment of the significantly regulated genes (P<0.05, FC>=2) in NT2/D1, HSerC and SLCs, compared to induced pluripotential stem cells (iPSCs) using ToppCluster. Similarities and differences in the transcriptome of the three Sertoli-like cell lines were visualized using Cytoscape.
Results: This approach revealed that SLCs and HSerCs are much more similar among each other (37 upregulated genes in common) than NT2d1 cells (only 3 upregulated genes in common). We observed that SLCs and HSerCs significantly expressed PAX2 and Hox gene complex from the Homeobox family, a renowned sub-family of genes expressed in both fetal and adult reproductive organs. Both Pax2 and Hox genes are linked to multiple steps of urogenital development and bipotential gonad formation. The functional redundancy among members of this large family may be masking a role in sex developmental defects. Of special interest is the observed significant upregulation of TBX18, (member of the T-box family), with some members of this family forming a complex with HOX proteins to initiate Sf1 gene expression during adrenal development.
Conclusion: Sertoli-like cells have proved to be a better model than the commonly used NT2d1 cells to study human Sertoli cells. Moreover, the comparison of high-quality Sertoli cell models highlighted several common genes that may conceal a not yet known role in male gonadal development.

The definition of a definite integral:
requires the interval [a,b] be finite. The Fundamental Theorem of Calculus requires that f be continuous on [a,b]. In this section, you will be studying a method of evaluating integrals that fail these requirements—either because their limits of integration are infinite, or because a finite number of discontinuities exist on the interval [a,b]. Integrals that fail either of these requirements are improper integrals. (If you are not familiar with L'Hôpital's rule, it is a good idea to review it before reading this section.)
Improper Integrals with Infinite Limits of Integration
Consider the integral
Assigning a finite upper bound in place of infinity gives
This improper integral can be interpreted as the area of the unbounded region between, (the -axis), and.
1. Suppose exists for all. Then we define
- = as long as this limit exists and is finite.
If it does exist we say the integral is convergent and otherwise we say it is divergent.
2. Similarly if exists for all we define
3. Finally suppose is a fixed real number and that and are both convergent. Then we define
We claim that
To do this we calculate
We claim that the integral
This follows as
To calculate the integral use integration by parts twice to get
Now and because exponentials overpower polynomials, we see that and as well. Hence,
Notice that we had to assume that to avoid dividing by zero. However the case was done in a previous example.
Improper Integrals with a Finite Number Discontinuities
First we give a definition for the integral of functions which have a discontinuity at one point.
Definition of improper integrals with a single discontinuity
If f is continuous on the interval [a,b) and is discontinuous at b, we define :=
If the limit in question exists we say the integral converges and otherwise we say it diverges.
Similarly if f is continuous on the interval(a,b] and is discontinuous at a, we define
Finally suppose f has an discontinuity at a point c in (a,b) and is continuous at all other points in [a,b]. If and converge we define
Notice that we had to assume that do avoid dividing by zero. So instead we do the case separately,
The integral is improper because the integrand is not continuous at x=2. However had we not notice that we might have been tempted to apply the fundamental theorem of calculus and conclude that it equals
which is not correct. In fact the integral diverges since
and and both diverge.
We can also give a definition of the integral of a function with a finite number of discontinuities.
Definition: Improper integrals with finite number of discontinuities
Suppose f is continuous on [a,b] except at points in [a,b]. We define as long as each integral on the right converges.
Notice that by combining this definition with the definition for improper integrals with infinite endpoints, we can define the integral of a function with a finite number of discontinuities with one or more infinite endpoints.
There are integrals which cannot easily be evaluated. However it may still be possible to show they are convergent by comparing them to an integral we already know converges.
Theorem (Comparison Test) Let f and g be continuous functions defined for all.
- Suppose for all. Then if converges so does
- Suppose for all. Then if diverges so does
A similar theorem holds for improper integrals of the form and for improper integrals with discontinuities.
Show that converges.
For all x we know that so. This implies that
We have seen that converges. So putting and into the comparison test we get that the integral converges as well.
Show that diverges.
Just as in the previous example we know that for all x. Thus
We have seen that diverges. So putting and into the comparison test we get that diverges as well.
An extension of the comparison theorem
To apply the comparison theorem you do not really need for all. What we actually need is this inequality holds for sufficiently large x (i.e. there is a number c such that for all ). For then
so the first integral converges if and only if third does, and we can apply the comparison theorem to the piece.
Show that converges.
The reason that this integral converges is because for large x the factor in the integrand is dominant. We could try comparing with, but as, the inequality
is the wrong way around to show convergence.
Instead we rewrite the integrand as
Since the limit we know that for x sufficiently large we have. So for large x,
Since the integral converges the comparison test tells us that converges as well.

Dog bite injuries to a child's face are not an infrequent occurrence. They may require primary and revisional surgery. All result in permanent facial scars. This report describes the treatment and outcomes of dog bites of the face, scalp, and neck based on a case series of 107 children over a 10-year period.
The average children's age was 5.9 years. In cases where the dog was identified (95%), it was known to the victim and their family. The events leading to the dog bite were categorized as provoked (77%) in the majority of the cases.
The majority of wounds could be closed primarily without a significant risk of wound infection. Complex reconstructions were required in more severe cases. The majority of families (77%) opted for scar revision between 9 and 18 months after initial treatment to improve the aesthetic outcome.
Lawsuit actions resulted in 39 of the cases making good documentation an essential part of treatment.
Dogbite injuries to the face in children frequently require multiple scar revisions to obtain the best possible aesthetic outcome, and the family should be so counseled at the onset of treatment.


Citrix ADC
Configure a stream identifier
You configure a stream identifier to specify parameters for collecting statistical data from requests identified by a given selector. An identifier specifies the selector to be used, the statistics collection interval, the sample count, and the field on which the records are to be sorted.
The Citrix ADC appliance includes the following built-in stream identifiers for common use cases. All the built-in identifiers specify a sample count of 1 and an interval of 1 minute. Additionally, they sort the data on the REQUESTS attribute. They differ only in being associated with different built-in selectors. Each built-in identifier is associated with a built-in selector of the same name (for example, the built in identifier Top_URL is associated with the built-in selector Top_URL). Following are the built-in identifiers:
 - Top_URL
For more information about the built-in selectors, see Configuring a Selector.
Note: The maximum length for storing string results of selectors (for example, HTTP.REQ.URL) is 60 characters. If the string (for example, URL) is 1000 characters long, of which 50 characters are enough to uniquely identify a string, use an expression to extract only the required 50 characters.
You cannot modify a built-in identifier's configuration. However, you can create an identifier with a configuration of your choice.
To configure a stream identifier by using the command line interface
At the command prompt, type the following commands to configure a stream identifier and verify the configuration:
 - add stream identifier [-interval ] [-SampleCount ] [-sort ]
 - show stream identifier
> add stream identifier myidentifier Top_URL -interval 10 -sampleCount 100
To configure a stream identifier by using the GUI
 1. Navigate to AppExpert > Action Analytics > Stream Identifiers.
 - To create a stream identifier, click Add.
 - To modify a stream identifier, select the identifier, and then click Edit.
 3. In the Configure Stream Identifier page, set the following parameters:
 - Name

Take the 2-minute tour ×
I would like to express the integral of the absolute value of a real-valued function $f$ (over a finite interval) in terms of the Fourier coefficients of $f$. Failing that, I would like to know of any constraints or statistical correlations (in a sense explained in the motivation) relating these quantities.
Motivation: This comes from a biophysics application, but is perhaps best explained as follows. If a rubber band of tension $t$ is stretched along the $x$ axis from $0$ to $L$, then it is easy to calculate the thermal fluctuations of its arc-length by letting $z(x)$ be the (small) deviation from the $x$ axis, and then writing the energy (arc-length times tension) in terms of the Fourier coefficients of $z(x)$. The Boltzmann weight turns out to be a Gaussian since in the limit of small deviations the arc-length becomes a sum of squares of the Fourier coefficients. My problem is more complicated: We have two rubber bands stretched over the same interval, with deviations $z_{1}(x)$ and $z_{2}(x)$. The energy includes not only the stretching of the rubber bands, but also a term proportional to the (positive) area enclosed between them, which is
$\int_{0}^{L}|z_{1}(x) - z_{2}(x)|dx$
Hence my question. So it would be nice to know how this area can be related to the Fourier coefficients of $z_{1}$ and $z_{2}$ or perhaps just to the arc-lengths of the rubber bands. By "statistical correlations" I am referring to the Boltzmann probability distribution with energy equal to the stretching energy plus the area-energy.
Edit: Specifics on the Boltzmann probability distribution, more motivation.
The state of the system is the pair of functions $z_{1}(x)$ and $z_{2}(x)$ describing the deviation of the two rubber bands from the x axis. Let's say it's the set of pairs of functions defined on [0,L] and that these functions are identified with a finite number of Fourier coefficients - I am a physicist and would like to avoid nasty functions or mathematically honest discussions of path integrals.
The probability of occurrence of a state (z_{1}, z_{2}) is (before normalization)
$\exp(-\beta E\left[z_{1},z_{2}\right])$
where $E\left[z_{1},z_{2}\right]$ is the energy of the system, which in this case is the functional
$E\left[z_{1},z_{2}\right] = \frac{t}{2}\int_{0}^{L}\left[(\frac{dz_{1}}{dx})^{2}+(\frac{dz_{2}}{dx})^{2}\right]dx + \kappa \int_{0}^{L}|z_{1}(x)-z_{2}(x)|dx$
Where the tension t and the "surface tension" $\kappa$ are just numbers; set them equal to 1 if you wish. The first integral is the energy cost of stretching the rubber bands (in a linearized regime) and the second is the strange term proportional to the area enclosed between them. Without the second term, it is easy to diagonalize this functional in terms of the Fourier series of the two functions. That is why I was interested in writing the second term in terms of Fourier coefficients. That may be too much to ask, but perhaps it is still possible to calculate some quantities such as the statistical average of $z_1(x)^{2}$ - that is the kind of thing I ultimately want to know.
I realize this is an unnatural-looking problem, so I will just mention that it's not really about rubber bands, but rather about fluctuating interfaces which occur in lipid bilayers with coexisting phases. There are two phase boundaries (one for each monolayer) with their respective "tensions" but there is also a term proportional to the area between them.

A comment in passing before proper answers appear: I do not think you can write L$_1$ norm in terms of the Fourier transform but L$_1$ norm is upper bounded by the L$_2$ norm which would be related to the length of the FT vector. I don't think it is possible to have an analogue of FT for L$_p$ norm for $p<2$. – Kaveh Khodjasteh Apr 23 '10 at 1:13

This sounds difficult. For instance, a long-standing open problem of Littlewood used to be this. Let A be a set of integers of size n, and let f be the characteristic function of A. How small (up to a constant) can the sum of the absolute values of the Fourier coefficients of f be? The conjecture was that the smallest was $C\log n$, which is what you get when A is an arithmetic progression. This conjecture is now known to be correct, but plenty of closely related questions are still open. So at least sometimes the relationship between the $L_1$ norm of a function and the Fourier transform of that function is quite hard to understand.

Well, the question was actually whether one can write any decent expression that gives an essentially equivalent measure on the set of states (whatever that means), so we do not need an equality that is always true, just an approximation that is accurate enough most of the time. Unfortunately, as far as I can tell, this is also rather hard if not impossible... On the other hand, some averages like the one mentioned in the post may still be possible to compute. Let me think a bit... – fedja Apr 24 '10 at 4:04
I walked down the hall to where the high-energy physicists are and my friend pointed out that this is probably equivalent to the path-integral formulation of a single quantum mechanical particle in a V-shaped potential - which can be solved analytically in terms of Airy functions. I think he is exactly right and the averages can be worked out that way. So the specific question about L_1 norms is probably misguided (but prompted an interesting connection above), while the statistical problem which seemed more difficult to me might be surprisingly tractable analytically... – Gregory Putzel Apr 24 '10 at 4:35
That last comment is about the statistical problem, by the way. – Gregory Putzel Apr 24 '10 at 4:51
This answer really has to do with the physics of it: are you sure about the area energy term?
Let me simplify a little bit: Consider a case where $z_1(x)=0$ and $z_2(x)=w(x)$. According to your formula I should get a term proportional to $w'(x)^2$ for the kinetic term which is typical and no one will object to you for that. You potential energy would then be proportional to $\int_0 ^L |w(x)| dx$. That does raise an alarm: nonlinear problem.
Unless you really have nonlinear physics going on (which is likely, see below) you should have had $w(x)^2$. That would bring back the $L_2$ norm and everything will be very simple. Just transform $z_2(x)=z_1(x)+w(x)$, get rid of $z_2$ and you will get two uncoupled (continuum of) modes, one (corresponding to $z_1$) is a free particle and the other a Harmonic oscillator. Your Boltzmann statistic will determine how these modes are filled up as you know.
If you think of your rubber band as a collection of springs and masses, $w(x)^2$ is the actual term but collections of springs and masses hardly exist outside textbooks and problem sets. As a physicist you know: molecules interact. The actual expansion (if you are still interested in writing an effective field theory) will involve (interacting) terms of the type $w(x)^2+O[w(x)^4]$. Quantitative results in this model might involve renormalization. See the wikipedia page on quartic interaction that even describes how you should quantize it (Fourier transform). My field theory is rusty so you might already know more than I do.
What if $|w(x)|$ is what you have: If $|w(x)|$ is not too small or too large, just approximate it with $[w(x)]^2$ to linearize the problem. People might point out that this is not a mathematically good approximation but it will physically make sense: very small stretchings are not physically possible and very large stretchings would be ruled out by the Boltzmann statistics as they would correspond to exponentially rare high energy modes. So I would just introduce a factor so that $w(x)$ and $w(x)^2$ coincide where

Theories of Altruism
Hedonism: acts of altruism are really selfish acts that benefit the actor
- Emotional satisfaction
- Reduction of negative feelings in the actor
Reciprocal altruism: natural selection favors animals that are altruistic
if the benefit to each is greater than the cost of altruism
- The bystander effect (BE) is a well studied, phenomenon (Darley and Latane and colleagues)
- BE is that people are less likely to provide needed help when they are in groups than when they are alone.
- Reviews of studies on over 6,000 subjects in a variety of helping situations indicate that subjects who are alone help about 75% of the time, while subjects in the presence of others help about 53% of the time.
- The bystander effect is believed to occur because of diffusion of responsibility – when the responsibility is divided among many, everyone thinks that someone else will help.

The Governor General is technically chosen by the Queen and is allowed to use almost all of the Queen's powers. But most of the time neither the Queen nor the Governor General use their powers without advice from the Prime Minister of Canada.
- The Queen would normally always choose whoever the Prime Minister wants them to choose to become Governor General.
- The Governor General usually uses his/her powers for what the Prime Minister advices him/her to do.
Once in a while the Prime Minister may want something done that the Governor General is not allowed to do on her own. The Prime Minister must then go straight to the Queen, for example for the appointment of 4 or 8 extra Senators to Parliament.

Running the Numbers
It's easy to read more into the yield numbers determined by the ISO/IEC standard than they actually mean. The first thing you need to know is that they don't represent a guaranteed number of pages you'll get from every individual cartridge—not even if you're printing only the set of pages defined by the standard. Basically, the stated yield is a statistical prediction that if you pick a cartridge at random and follow the procedures in the ISO/IEC standard, you'll get at least that number of pages more than 90 percent of the time.
To calculate the yield for what the ISO/IEC standard calls a primary cartridge—black or tricolor, for example—you start with the individual results from a minimum of nine cartridges. More precisely, you need results from a minimum of three sets of three cartridges tested on each of three printers, to take variations among both individual printers and cartridges into account. (The standard defines a different approach for what it calls supplementary cartridges, such as light cyan or light magenta, but for our purposes that's an unnecessary complication.)
You have to run the results through basic statistical formulas to determine what's called the "90 percent lower confidence bound." That number gets reported as the yield. —next: Understanding the Yield Numbers >

The preparation of sewage sludge biochar (SSB) and its impacts on soil characteristics, plant health, nutrient leaching, and greenhouse gas emissions (GHGs) are critically reviewed in this study. Comparing the features of SSB obtained at various pyrolysis temperatures revealed changes in its elemental content. Lower hydrogen/carbon ratios in SSB generated at higher pyrolysis temperatures point to the existence of more aromatic carbon molecules. Additionally, the preparation of SSB has an increased ash content, a lower yield, and a higher surface area as a result of the rise in pyrolysis temperature. The worldwide potential of SS output and CO2-equivalent emissions in 2050 were predicted as factors of global population and common disposal management in order to create a futuristic strategy and cope with the quantity of abundant global SS. According to estimations, the worldwide SS output and associated CO2-eq emissions were around 115 million tons dry solid (Mt DS) and 14,139 teragrams (Tg), respectively, in 2020. This quantity will rise to about 138 Mt DS sewage sludge and 16985 Tg CO2-eq emissions in 2050, a 20% increase. In this regard, developing and populous countries may support economic growth by utilizing low-cost methods for producing biochar and employing it in local agriculture. To completely comprehend the benefits and drawbacks of SSB as a soil supplement, further study on long-term field applications of SSB is required.

The 1940 documentary short "Quicker'n a Wink" fascinated people with its slow-motion imagery of things like the beating of a hummingbird's wings; it won a 1941 Academy Award. One of the revelations from the movie was that a cat curls its tongue backwards into a "J" when it goes to take a drink of liquid, letting the top of its tongue touch the surface first.
But kitties aren't using their tongues like ladles, scooping up water, says a new study published yesterday in Science. Cats simply have to brush their tongues along to the surface of the liquid and let the power of physics bring it into their mouths.
The scientists used high-speed imaging to watch cats—including one researcher's own pet, Cutta Cutta—lapping up milk, sometimes spending hours just waiting for the cat to get thirsty. Each cat would dip its tongue towards the liquid, just brushing the surface, not piercing it. When it lifted its tongue, the liquid adhered to the tip of the tongue and was drawn upward in a column (as in the above photo), thinning as the cat drew its tongue into its mouth. Just before the column would break, the cat would close its mouth and trap the milk, storing it in cavities inside and swallowing after every three to 17 of these lapping cycles.
This small act seems to defy gravity, but in actuality the cats have figured out how to keep a delicate balance between inertia—the tendency of the liquid to keep moving in the same direction—and the gravitational forces pulling the milk back into the bowl. Domestic cats don't bring up a lot of liquid in each lap, only about a tenth of a milliliter, but they do it quickly, at a rate of about four laps per second.
When the scientists watched high-speed and YouTube video of larger kitties, such as lions and tigers, they found that the bigger cats' tongues worked the same way, but they lapped at a slower rate. The researchers were able to develop an equation that predicted lapping frequency based on animal mass.
"The amount of liquid available for the cat to capture each time it closes its mouth depends on the size and speed of the tongue. Our research…suggests that the cat chooses the speed in order to maximize the amount of liquid ingested per lap," says study co-author Jeffrey Aristoff, a mathematician at Princeton University. "This suggests that cats are smarter than many people think, at least when it comes to hydrodynamics."

The Articulated Total Body Model (ATB) is used for predicting gross segmented body response in various dynamic environments. The ATB computer program, originally written by the Department of Transportation as a Crash Victim Simulation (CVS) program, was later modified by the Calspan Corporation and More recently by the Armstrong Aerospace Medical Research Laboratory (AAMRL) to allow for aerodynamic force applications, harness belt capabilities and hyper-ellipsoidal graphical display of the modeled segments. The ATB model has been successfully used to investigate gross human body responses to bodies placed in such complex dynamic environments as high-speed aircraft ejection. This ATB model is quite versatile due to the variety of inputs it can handle. Because of this versatility, a wide range of physical systems may be simulated.
In this work, the ATB computer program has been modified for use on the Apollo workstation and utilized to predict limb and joint limitations a modeled human arm for the purpose of creating more effective rehabilitation schedules. A patient's left shoulder, left-upper and left-lower arm have been modeled for a case study. The required information consists of segment physical dimensions, weight.center of gravity and maximum forces and torques obtainable from various body muscles. From this information, forces a graphical display of desired segment positions, and numerical approximations of forces, torques, positions, velocities, and accelerations of any desired point of the modeled segment. A comparison of this numerical output found from the ATB will be made with actual patient response, further input will be created tracking the patient's rehabilitation progress. A mathematical model of this will be incorporated into the ATB for the purpose of predicting future patient responses and a predicted schedule for disabled patient rehabilitation.An accurate numerical and visual prediction of patient responses and limitations would be very beneficial in the creation of rehabilitation schedules. For such a service to be obtainable in a hospital environment, the ATB must be executable on a personal computing level. The Apollo workstation was selected for this project due to its relative mobility and availability. Many similar computing systems could be used where the criteria of mobility, large memory capabilities and superior graphics are obtainable. These criteria must be met so that the ATB could eventually be used by physicians in a clinic or office environment.

Can anyone explain why the following two statements both evaluate as true?
[] == false
This question is purely out of curiosity of why this happens and not about how to best test if an array is empty.
share|improve this question
If you really want to get your hands dirty, take a look at section 11.9.1 ("The Equals Operator ==") and Section 8.7.1 ("GetValue(V)") in the spec. And this would be another great example of why == true and == false are generally not ideal style. :-) – T.J. Crowder Nov 19 '10 at 15:21
Actually, using == or!= is never good style. Always use === or!==, and cast the operands by hand. – Marco Mariani Nov 19 '10 at 15:56
[] == []; // false – Florian Margaine Nov 6 '12 at 9:56

The first one:
[] == false
The == operator does type conversion to its operands, in this case the both sides are converted to Number, the steps taken on the Abstract Equality Comparison Algorithm would be:
 - object == boolean
 - object == number
 - string == number
 - number == number
In code:
[] == false; // convert false to Number
[] == 0; // convert [] to Primitive (toString/valueOf)
"" == 0; // convert "" to Number
0 == 0; // end
The second comparison, [] is converted to primitive, their valueOf and toString methods are executed, but since valueOf on Array objects, returns the object itself (is inherited from Object.prototype), then the toString method is used.
At the end as you see, both operands are converted to Number, and both yield zero, for example:
Number([]) == 0;
Number(false) == 0;
And empty array produces zero when converted to Number because its string representation is an empty string:
[].toString(); // ""
And an empty string converted to Number, yields zero:
+""; // 0
Now, the double negation (!![]) produces true because all object instances are truthy:
![]; // false, [] is truthy
!![]; // true, negation
The only values that are falsey are:
 - null
 - undefined
 - 0
 - NaN
 - "" (an empty string)
 - false
Anything else will produce true when converted to Boolean.

Very interesting. Thanks for the detailed description and sharing those links. – Matthew Manela Nov 19 '10 at 15:51
Whoops, looks like I answered the same question in the same way. Didn't notice until someone marked that question a duplicate of this one. – Nick Retallack May 11 '12 at 19:23
[] == false
In this case, the type of the left-hand side is object, the type of the right-hand side is boolean. When object is compared to (== The Abstract Equality Comparison) boolean, Javascript first converts the boolean to a number, yielding 0. Then it converts the object to a "primitive", yielding the empty string "". Next it compares the empty string to 0. The empty string is converted to a number, yielding 0, which is numerically equal to the 0 on the right-hand side, so the result of the entire expression is true.
Ref: 11.9.3 The Abstract Equality Comparison Algorithm
In this case Javascript converts the object to the boolean true, then inverts it, resulting in false.

Dalkeith Castle was located to the north east of Dalkeith, and was originally in the hands of the Grahams in the 12th century and given to the Douglas family in the early 14th Century. James Douglas of Dalkeith became the Earl of Morton in the mid 15th century. The castle was strategically located in an easily defensible position above a bend in the North Esk River. In 1543, Cardinal Beaton was imprisoned in Dalkeith Castle. It was forced open and destroyed by the English in 1547, and in 1575 the 4th Earl of Morton built a new castle there. In 1642 Dalkeith Castle was sold to the 2nd Earl of Buccleuch.
The 2nd Earl of Buccleuch's daughter married the Duke of Monmouth, eldest natural son of Charles II. They became Duke and Duchess of Monmouth & Buccleuch. When the Duke of Monmouth died his widow, Anne, asked architect James Smith to use William of Orange's Palace of Het Loo in Holland as a model for Dalkeith Palace.
Smith and his cousins, Gilbert and James, signed the contract for masonwork at Dalkeith Castle in March of 1702. Construction of Dalkeith Palace began later that year, Smith deciding to incorporate a portion of the tower house of the old castle into the western side of the new structure. The outline of the old tower walls is still visible in the western facade of the palace today. In 1704, William Walker and Benjamin Robinson, the chamberlain of the Duchess, went to London with a small party to choose items of furniture for the palace. Construction was proceeding at a steady pace, and the main portion of the palace was roofed by the end of 1705. The London marble-cutter Richard Neale spent sixty-four weeks at the palace with nine assistants between 1709 and 1711, carving the main stairwell and screen of the Great Staircase. Several marble chimney pieces were installed, as well as an intricately-carved marble bas-relief of Neptune and Galatea. This internally extensive use of marble was very much the taste of the Duchess. The majority of construction was complete by 1711.
Finishing touches on the Palace complex included adding a wrought iron screen with freestone piers (no longer existing) around the forecourt, a great deal of planting, and the laying out of a great avenue through the park. Dalkeith Park itself was a large area of manicured trees and gardens which in later years would include the Montagu Bridge over the North Esk River and the Dalkeith Conservatory and a grassed amphitheatre. When the final calculations were made, it was determined that the construction of Dalkeith Palace had cost the Duchess a total of 17,727 pounds sterling.
The plumber John Scott of Edinburgh re-plated the roof in lead in 1743. Some minor additions were carried out in the following years. John Adam resurfaced the building in 1762 and James Playfair inserted a low window into the east facade in 1786.
Overall, the Palace is built of sandstone and has the main entrance on the south front, flanked on each side by two Corinthian order pilasters. These are surmounted by a bracketed pediment unusual for its depth.
The layout of Dalkeith Palace was unusual for the time in that the state apartment was located on the ground floor, which prevented the Great Dining Room from being placed in its customary position at the start of the state apartment. As such, the Great Dining Room was placed on the first floor, still suitable for important occasions and also serving as an anteroom to another apartment on the first floor. The 4th Duke considered extensive rebuilding in 1831 and William Burn produced unexecuted designs in Jacobean style. More minor alterations were carried out, together with improvements to the surrounding estate including a new house and offices for the Duke's Chamberlain, and the construction for the 5th Duke of St Mary's Church as a private chapel by William Burn and David Bryce. The Church contains one of only two water-powered organs in Scotland.
Several well-known figures from English and Scottish history have been guests at the Palace in the intervening centuries. Bonnie Prince Charlie stayed two nights at Dalkeith in 1745, George IV slept here during his visit to Edinburgh in 1822, in preference to the Palace of Holyroodhouse which was in a poor state, as did Victoria in 1842.
During World War II, Polish troops were quartered on the third floor of Dalkeith Palace. Their task during the Battle of Britain was to man Lewis Guns on the Palace roof and fend off any Luftwaffe air attacks that might occur. Graffiti drawn by these troops is still visible on the third floor wallpaper of the Palace as of 2004.
Today, the 9th Duke of Buccleuch resides at Bowhill, near Selkirk. Dalkeith Palace has not been lived in by the Buccleuch family since 1914 and is leased to the University of Wisconsin as a base in Scotland. The Smith family, including James Smith member of the punk band Threats and his son Rikki Smith, are current caretakers to the palace.

Five tips for reducing Exchange Server support costs
A few simple steps can make a big difference in what you spend to support your Exchange Server organization. Brien Posey shares several practical suggestions.
The current economic climate continues to drive organizations to look for ways to reduce IT costs. Here are five things you can do to cut costs on Exchange Server support.
1: Take advantage of Role Based Access Control
One of the best ways to reduce Exchange Server support costs (while reducing your own workload in the process) is to take advantage of Exchange 2010's Role Based Access Control (RBAC) feature. RBAC allows you to delegate degrees of administrative permissions to non-Exchange administrators so that they can perform specific tasks.
For example, there is a management role group named Help Desk, to which you can assign help desk staff. Members of this role group can perform basic administrative tasks, such as modifying user information (address, phone number, etc.). It is worth noting that in Exchange Server 2010, end users can be allowed to modify their own information through Outlook Web App. As strange as it may sound, members of the Help Desk group are allowed to modify only information that users are allowed to modify themselves. Therefore, if you prevent users from modifying their own information, you will block the Help Desk from doing so as well.
The Help Desk Group is only one of the RBAC groups. You can use RBAC to provide truly granular Exchange Server permissions. For instance, you could potentially lighten the administrative burden by designating another staff member to act as a recipient manager (which would allow that person to create and maintain user mailboxes).
2: Proactively monitor the server's health
Another major step you can take to reduce Exchange Server support costs is to be proactive in your server maintenance. A number of tools are on the market for monitoring Exchange Server's health, and I highly recommend investing in such a tool. Although you'll have to spend some money up front, the tool will likely reduce your costs in the long run. Exchange Server monitoring tools are designed to spot small problems so that you can correct them before they turn into big problems. This not only helps reduce down time, but it also reduces costs by doing the troubleshooting for you.
3: Use dedicated Exchange servers
Whenever possible, you should run Exchange on dedicated servers (physical or virtual) rather than attempting to host additional roles, services, or applications on an Exchange server. Using dedicated servers eliminates the possibility of an unrelated service or application interfering with Exchange.
Using dedicated servers also helps improve security because a dedicated server has a smaller attack surface than a server that's performing multiple duties. Furthermore, if anything does go wrong with the Exchange server, the problem is often easier to troubleshoot if Exchange is the only thing running on the server.
4: Build redundancy into your Exchange Server organization
Few things drive up support costs the way an unanticipated failure does. Several types of costs are incurred when a server fails. First, there is the cost of paying the IT staff to fix the problem. There may also be costs associated with replacement parts or support calls to Microsoft. Although such costs can be significant, they are minor in comparison to the costs that occur because of how the failure affects the end users.
If users are affected by a failure, they can't properly do their job. At best, this means they're being paid to wait around for the server to come back up. At worst, an Exchange Server failure translates directly to lost revenue because customers are unable to communicate with employees.
While you may not always be able to completely prevent failures from occurring, you can prevent users from being affected by those failures by building redundancy into your Exchange Server organization. Microsoft supports failover clustering only for mailbox servers, but you can achieve redundancy for other Exchange Server roles through load balancing.
5: Periodically run the Exchange Server Best Practices Analyzer
Finally, I recommend that you periodically run the Exchange Server Best Practices Analyzer (ExBPA). In case you're not familiar with the ExBPA, it's a free tool that analyzes your Exchange Server organization to make sure your configuration adheres to Microsoft's recommended best practices. The Best Practices Analyzer started life as a downloadable tool, but it's now included in the Exchange Management Console Toolbox section in Exchange 2007 and Exchange 2010.
I recommend periodically running the tool because Microsoft is known to change its recommendations from time to time. As Microsoft's recommended best practices evolve, those changes are reflected in the ExBPA. As a general rule, I suggest running the ExBPA once a month or any time you make a configuration change.
