The Outdoor Terrarium
By: Frank Indiviglio
Read By: Pet Lovers
Reptiles and amphibians can do well in an outdoor terrarium, and you can get to observe them closely in a habitat that's more natural than life indoors. But to succeed you have to use special care in creating a safe and healthy environment for your pet.
Watching an animal catch its prey, or mate and brood its young in the wild, are events that frequently elude even dedicated herpetologists. But they can be common events for pet owners who allow their reptiles and amphibians to experience normal seasonal cycles. What you observe and enjoy may even inspire an interest in further field research and observation.
Extra space, often more readily available outdoors, can contribute to the overall health of a reptile or amphibian and can be vital for reproduction in nearly any species you decide to keep. It can help, for example, in breeding large aquatic frogs such as American bullfrogs, large aquatic turtles such as Florida softshells and medium-sized monitor lizards.
Small Space Needed for Terrarium
You can create such a terrarium in an area as small as 4 feet by 4 feet as long as it has a supply of fresh water. The terrarium itself may be constructed of any number of materials, from weatherproof wooden posts with chicken wire to concrete or fiberglass enclosures. A 4-by-4 foot enclosure will be large enough to keep five or six medium-sized frogs or turtles.
To create natural diversity, you can include small ponds (great for keeping salamanders such as mudpuppies and sirens) in your terrarium. Pond shops have all sizes and shapes along with ways to filter the water. Flowering plants, piles of rotting wood, dead leaves and bits of fruit and meat will attract a wide variety of insects for your animals to feed on. You can also "seed" enclosures with millipedes, snails, and other invertebrates that will reappear and provide unique hunting opportunities for your pets. Beyond this you may find that little additional food is required.
Space Can Make Reptiles Territorial
One drawback: Behaving naturally for many species means being secretive. While some become bolder, others become difficult to approach after a time "in the wild." Territorial aggression may also crop up in animals suddenly given space to claim as their own. Even relatively sociable animals in cages and aquariums, such as Cuban crocodiles, American bullfrogs or snapping turtles, can become highly territorial in the open.
You can address these problems by keeping an eye on your pets – as you must under all circumstance – to check their physical appearance for signs of health problems. This will not be as easy as peering into a tank in your den. You'll need to set up lookout stations around the site from which you can observe your pet's physical appearance and behavior unobtrusively.
Elevated stations (platforms in trees are sure to puzzle or amuse your neighbors) will allow you to observe your pet's daily activities and condition, although you still may want to do regular weighings to ascertain that your pet is thriving. For nocturnal viewing, you can install a special red light (available through reptile supply companies) that is invisible to your pets. Indirect lighting with a regular incandescent bulb also works for some species. Depending upon your level of interest (or mania), you may even wish to consider night vision glasses.
Location is Important
Terrarium location is important for providing the proper balance of shade and sunlight. Under the best circumstances, the animals will have access to morning sun and available water and shade for cooling off in the heat of the afternoon.
How you keep the animals inside from getting out depends upon the animal. A bullfrog can jump 6 feet in the air, but if the enclosure contains a small pond the frogs will usually remain where they are. Turtles can scale low walls but an overhang will keep them in. Sinking the enclosure fencing a bit below the surface will keep animals from digging their way out.
Keeping unwanted predators out is another problem. Raccoons and even coyotes now often live in urban and suburban areas. And while most dogs can't scale fences, cats can, so providing a cover for a containment of sensitive animals will be important. Even songbirds can be tenacious little hunters of small reptiles and amphibians.

MIAMI (CBS4) — Florida's gopher tortoise population deserves to be added to the nation's list of endangered and threatened species but funding shortages could delay the listing for years, federal wildlife officials said on Tuesday.
There is sufficient scientific data to list the gopher tortoise as threatened in parts of Florida, Alabama, Georgia, and South Carolina, said Cindy Dohner, the U.S. Fish and Wildlife Service's regional director for the Southeast.
"But we do not have the resources to pursue the listing process at this time," she told reporters during a conference call, noting the process can cost $300,000 or more.
The gopher tortoise, which is sandy brown in color and can grow to up to 15 pounds, will instead join a list of 251 other species designated as candidates for federal protection, meaning wildlife managers acknowledge their survival is in danger but they don't have the money to do anything about it.
It's unclear how long it will take to draw up a full recovery plan, which includes mapping out critical habitat, much of which is in Florida, particularly Central and North Florida. State wildlife managers designated the turtle as a "threatened" species in 2007 and, after public outcry, banned a cold-hearted practice that had allowed developers to bury more than 70,000 of them alive.
The tortoise is threatened by habitat loss, herbicides used in forestry and other factors, federal officials said.
Scientists consider the turtle, which can live a half century, a "keystone species" because its deep network of burrows help support some 360 other species, including snakes, rodents, skunks and rabbits. But some landowners consider it a nuisance because they see it as a potentially expensive hurdle to development plans.
Under a Florida Fish and Wildlife Conservation Commission plan adopted in 2008, builders must obtain a permit to build in gopher tortoise habitat and agree to relocate any found. As an incentive, the state will reduce permit costs if developers place them in high-quality habitat or set aside other areas for turtle use. It's illegal to kill or move the tortoises or eggs without a state permit.

PBDEs and legacy POPs in urban birds of prey partly explained by trophic level and carbon source
Science of the Total Environment
POPs, PBDEs, Raptor, Urban ecosystems, Stable isotopes, Predator
As urban sprawl and agricultural intensification continue to invade prime wildlife habitat, some animals, even apex predators, are managing to adapt to this new environment. Chemical pollution is one of many stressors that wildlife encounter in urban environments. Predators are particularly sensitive to persistent chemical pollutants because they feed at a high trophic level where such pollution is biomagnified. To examine levels of pollution in urban birds of prey in the Lower Mainland region of British Columbia, Canada, we analyzed persistent organic contaminants in adult birds found dead of trauma injury. The hepatic geometric mean concentration of sum polybrominated diphenyl ethers (∑PBDEs) in 13 Cooper's hawks (Accipiter cooperii) from Greater Vancouver was 1873 ng/g (lipid weight) with one bird reaching 197,000 ng/g lipid weight, the highest exposure reported to date for a wild bird. Concentrations of ∑PBDEs, ∑PCBs (polychlorinated biphenyls) and, surprisingly, cyclodiene insecticides were greatest in the urban environment while those of DDE (1,1-dichloroethylene bis[p-chlorophenyl) were highest in a region of intensive agriculture. The level of most chlorinated and brominated contaminants increased with trophic level (δ15N). The concentrations of some contaminants, PBDEs in particular, in these birds of prey may have some toxicological consequences. Apex predators in urban environments continue to be exposed to elevated concentrations of legacy pollutants as well as more recent brominated pollutants.

- Financial Literacy
Are your middle school students prepared to make sound economic decisions in the ways of income, spending, saving, borrowing, investing and managing money? The Financial Fitness for Life materials were written based on real-world concepts, and let teachers present them in a manner that reinforces learning through practice, helping prepare students for life beyond the classroom.
The Grades 6-8 Teacher Guide was designed to be used with Financial Fitness for Life's student workbooks to teach personal finance. You will measure your students' progress in four themes of personal finance: earning an income, saving, spending and credit, and money management. Between these four themes there are 17 lessons, each focusing on a different topic and ranging in length from one 45-minute period to a week's worth of classroom experience.
Lessons for older students illustrate certain uses of more abstract representations. Specific to grades 6-8 are a variety of activities, including developing criteria that students think would make a good graham cracker and taste-testing to determine which graham cracker meets their needs; deciding which activities are better suited to careers or hobbies; and learning how important planning is to the success of any goal or event.
You will have two practical resources at your disposal:
- Visuals are contained within the book for reinforcing the concepts in each chapter.
- The Financial Fitness for Life website, created as a partner resource for the book, contains visuals and activities. Teachers can also access online lessons to extend student activities and find related materials to each lesson.

The Resurrection of Hungary: A Parallel for Ireland.
GRIFFITH, Arthur (Introduction by Patrick Murray).
University College Dublin Press, 2003 (reprint). First published 1904. xxxii, 170 pages. Paperback.
"The case of Ireland is as nearly as possible parallel to the case of Hungary" - William Smith O'Brien. The Resurrection of Hungary, first published in 1904 and twice reprinted, strongly influenced nationalist debate between 1904 and 1921. Its central proposal - the withdrawal of Irish elected representatives from Westminster - was inherited from the Hungarian Franz Deak's policy of non co-operation with the Imperial parliament in Vienna in the 1860s. The idea of the dual monarchy, adopted by Austria and Hungary in 1867 in which each recognised the Austrian Emperor but had separate parliaments, continued to be advocated by a few Irish politicians in the 1920s. Griffith also expounds here his protectionist economic views which influenced Irish government policy for several decades. Arthur Griffith (_PHONE_) was a journalist and politician. He founded Sinn Fein in 1905, and at the time of his sudden death was President of Dail Eireann. (reprint).

Thixotropic Index (TI)
Definition - What does Thixotropic Index (TI) mean?
This is a ratio between the slow speed viscosity to the high speed viscosity of a non-Newtonian body. It is obtained from dividing the viscosity number at low speed by the viscosity number at high speed of a given fluid. It therefore defines how well the fluid will hang or resist sagging under gravity.
It is used to indicate the ability of a paint or coating to hold shape-stiff and non-sagging when rebuilding; aids in choosing an epoxy in accordance to the application, dispense method and viscosity of a material.
Corrosionpedia explains Thixotropic Index (TI)
Non-Newtonian fluids are known to have a low viscosity when stirred at high speed and high viscosity at low speeds. In these fluids, the energy required to move then is not directly equal to the speed applied. At rest, the fluid will not flow, but when subjected to shear or pressure, it flows easily as the agitation increase. A fluid is thixotropic when the apparent viscosity is recovered when the shearing is removed; the recovery is time-dependent—viscosity decreases gradually with time.
The thixotropic index is obtained by measuring the viscosity of a fluid at room or ambient temperature. The viscometer is used to measure the viscosity at two speeds (one is a multiple or a factor of 10 of the other). From the viscosity results, the product is obtained by dividing the viscosity at lowest speed by the viscosity at the highest speed.

Gene Davis (painter)
"Black Grey Beat," (1964), acrylic on canvas, collection:Smithsonian American Art Museum
August 22, 1920|
|Died||April 6, 1985
|Training||University of Maryland|
|Movement||Washington Color School, Color Field painting, Post-painterly Abstraction|
|Influenced by||Paul Klee|
Gene Davis (August 22, 1920 - April 6, 1985) was an American painter known especially for his paintings of vertical stripes of color, and was a member of the group of abstract painters in Washington DC during the 1960s, known as the Washington Color School.
Davis was born in Washington D.C. in 1920 and spent nearly all his life there. Before he began to paint in 1949, he worked as a sportswriter, covering the Washington Redskins and other local teams. Working as a journalist in the late 1940s, he covered the Roosevelt and Truman presidential administrations, and was often President Truman's partner for poker games. His first art studio was in his apartment on Scott Circle; later he worked out of a studio on Pennsylvania Avenue.
Davis's first solo exhibition of drawings was at the Dupont Theater Gallery in 1952, and his first exhibition of paintings was at Catholic University in 1953. A decade later he participated in the "Washington Color Painters" exhibit at the Washington Gallery of Modern Art in Washington, DC, which traveled to other venues around the US, and launched the recognition of the Washington Color School as a regional movement in which Davis was a central figure. The Washington painters were among the most prominent of the mid-century color field painters. Though he worked in a variety of media and styles, including ink, oil, acrylic, video, and collage, Davis is best known by far for his acrylic paintings (mostly on canvas) of colorful vertical stripes, which he began to paint in 1958. The paintings typically repeat particular colors to create a sense of rhythm and repetition with variations. One of the best-known of his paintings, "Black Grey Beat" (1964), owned by the Smithsonian American Art Museum reinforces these musical comparisons in its title. The pairs of alternating black and grey stripes are repeated across the canvas, and recognizable even as other colors are substituted for black and grey, and returned to even as the repetition of dark and light pairs is here and there broken by sharply contrasting colors.
In 1972 Davis created Franklin's Footpath, which was at the time the world's largest artwork, by painting colorful stripes on the street in front of the Philadelphia Museum of Art, and the world's largest painting, Niagara (43,680 square feet), in a parking lot in Lewiston, NY. His "micro-paintings", at the other extreme, were as small as 3/8 of an inch square.
For a public work in a different medium altogether, he designed the color patterns of the "Solar Wall," a set of tubes filled with dyed water and backlit by fluorescent lights, at the Muscarelle Museum of Art at the College of William and Mary in Williamsburg, Virginia.
Davis began teaching in 1966 at the Corcoran School of Art, where he became a permanent member of the faculty. His works are in the collections of, among others, the Corcoran Gallery of Art, the Solomon R. Guggenheim Museum, The Phillips Collection in Washington, DC, the Walker Art Center in Minneapolis, MN, and the Smithsonian American Art Museum.
He died on April 6, 1985 in his hometown of Washington, DC.

ChainIn set theory, a chain is a totally ordered subset of a partially ordered set. In algebraic topology, a chain is a formal combination of simplices.
A chain is a measurement of length equivalent to 22 yards (20.12 metres), which is one tenth of a furlong or one eightieth of a mile. It was used in surveying land in England and places under English influence, such as the United States, but is obsolete in many places. It is also called the surveyor's chain or Gunter's chain after 17th century mathematican and astronomer Edmund Gunter, who introduced it. The distance of 22 yards is the length of the pitch (from wicket to wicket) in cricket.
The engineer's chain or Ramden's chain of 100 feet (30.48m) was also used.

Australian Medicare Number Validation
Australian Medicare card numbers consist of 11 digits structured as follows:
First digit should be in the range 2-6
Digits are weighted (1,3,7,9,1,3,7,9)
Issue Number
Indicates how many times the card has been issued
Individual Reference Number (IRN)
The IRN appears on the left of the cardholder's name on the medicare card and distinguishes the individuals named on the card.
The IRN is not always considered part of the card number, but it is essential that it be included on Medicare claim forms.
It can be hard to find a definitive reference to the algorithm on the Medicare site. At the time of writing it could be found in this document:
Try It!
Sample Code
// ValidateMedicareNumber
// Checks medicare card number for validity
// using the published checksum algorithm.
// Returns: true if the number is valid, false otherwise.
// Note - this expects 11 digits including the IRN.
// To validate numbers without IRNs, change the length
// check to 10 digits.
// Source:
// Author: Guy Carpenter
// License: The author claims no rights to this code.
// Use it as you wish.
function ValidateMedicareNumber($MedicareNo)
 $medicareNo = preg_replace("/[^\d]/", "", $MedicareNo);
 // Check for 11 digits
 $length = strlen($medicareNo);
 if ($length==11) {
 // Test leading digit and checksum
 if (preg_match("/^([2-6]\d{7})(\d)/", $medicareNo, $matches)) {
 $base = $matches[1];
 $checkDigit = $matches[2];
 $sum = 0;
 $weights = array(1,3,7,9,1,3,7,9);

text: Keeping in mind the supreme benefit of the ātmā the Pradhāna initiates the creation in the form of mahat, etc. Hence it is inappropriate that the Puruṣa (sentient being) is independently the cause of the creation by deliberation. When the creator Pradhāna that is the state of equilibrium of the guṇa-s sattva, etc. is present as backed by authority (pramāṇa), or while the subtle atoms, paramāṇu-s, are present impelled by an Īśwara, it is unreasonable to propose a creation by the Ātman. Why? The Ātman is admitted as One only without any instrument/material with which he could create. Also, Ātman would not logically bring about a creation where everything is detrimental to the Ātman's interest. In other words, a sentient Ātman would not create a world full of misery and other defects. Therefore it would be correct to conclude that it is the Pradhāna, though insentient, is taught, by courtesy, in this Upaniṣad to indulge in a creation preceded by deliberation of the benefit to the sentient Ātman, as though a sentient entity would. This is akin to holding an officer to be the king, by courtesy, by virtue of the former performing everything required by the king.

CPaaS 3.0: 5 methods of transforming customer experience strategies
CPaaS 3.0: 5 methods of transforming customer experience strategies
CPaaS 3.0 and customer experience strategies
For the past period, marketers have found it difficult to raise customer satisfaction rates. Despite this, 70% of businesses plan to leverage CPaaS (Communications-Platform-as-a-Service) as part of their customer experience (CX) strategies. This is because it offers the solution to low engagement rates and addresses the recent shift in consumer behavior.
With fewer people leaving their homes, a 'homebody economy' is growing. Yet, wise marketers know that more personal interactions will lead to better customer retention.
With its seamless, omnichannel approach, CPaaS 3.0 offers a chance to meet customers where they are. It's also offering businesses an exciting way to achieve their digital transformation.
What has changed for customer experience in the post-COVID recovery?
Expectations of customer care have changed. Here are a few of the trends that have emerged:
More focus on safety, security, and empathy: Consumers are more concerned with how a business treats its staff. They also want to limit any risk to their hygiene or their data.
Faster, more convenient service: Now, customers are expecting a 24/7 multi-channel experience. Plus, they want it to meet their needs in real-time. For example, Commercial International Bank (CIB) automated their customer workflows and achieved a faster response rate.
Increased emphasis on company values: 80% of consumers say sustainability is now very important. And since the pandemic has increased awareness of environmental risks, more companies are emphasizing low carbon footprints or ethical approaches.
Bigger appetites for innovation and experimentation: Around 50% of consumers say they're more willing to try novel approaches. As a result, businesses are working harder to translate brand values into tangible and innovative actions.
5 ways CPaaS 3.0 will transform customer experience strategies
So how can strategists use CPaaS 3.0 to address these needs? Here are 5 methods to consider:
1. Human-Centered Design (HCD)
Human-Centered Design (HCD) is a creative design-thinking approach developed by IDEO. It sits at the intersection between empathy, creativity, and the needs of businesses. Because it's human-centered, it helps businesses focus on meeting people's needs. While it established itself as a process for product design, Human-Centered Design principles are transferrable to customer experience strategies.
Businesses who put Human-Centered Design principles at the heart of their customer experience understand how their customers feel. And with this knowledge, they can design customer journey touchpoints to respond to those feelings. With its increased agility, CPaaS 3.0 makes it easier to empathize with customers.
2. Simplified development
CPaaS 3.0 includes server-less and no-code capabilities. This means coding, debugging, and scaling is much easier. Also, it's aided by new Integrated Development Environments (IDE's). No-code features also make the platform accessible to non-developers. This enables quicker and easier integration of multi-channel apps.
Along with two-factor authentication implemented in SMS, businesses are stepping further towards addressing security concerns. Besides, enhanced automation is increasing transactional messaging to customers. Ultimately, this matches customer expectations for 'always on' services.
3. AI and Machine Learning
Real-time intelligence will revolutionize the customer experience. Because of improved features to speech synthesis, easier deployment of AI in call centers, and better integration of chatbots in a real-time interface, customer experience is pushing technology to have a more human experience.
Video conferencing is now a norm for our daily interactions. But this new platform will make virtual and augmented reality a more supportive element of the customer experience.
4. Employee experience (EX)
Staff teams are now more reliant on digital connections. Like customers, employee expectations are shifting to assume more seamless interactions. However, where more employees are working from their homes, they need more opportunities to connect.
With its instant and flexible enhancements, CPaaS 3.0 is giving quicker access to information. It's also increasing opportunities for connection and collaboration. Additionally, when employees are happier, they're better able to support your customers.
5. Internet of Things (IoT)
There are now more devices in the world linked to the Internet of Things (IoT) than humans. Because of the complex signals these devices send to each other, more companies are driving efficiency, productivity, and strengthening customer loyalty. By moving away from the basic API function, the interconnectivity of devices is being enhanced by CPaaS 3.0. This is moving us closer to an interconnected and more automated future.

text: In the near future, your strappy sundress or gold bangles may recognize your urge to overeat—and stop you before you start. Computer scientists including a team from Microsoft Research have developed a system of wearable devices that detect signs of impending emotional eating. Over four days, a test group used a phone app to log information about their mood and meals, while sensor pads in their clothing measured their breathing, sweating, and heart rate. This data enabled the researchers to predict physiological and emotional states that precede individual patterns of stress-related eating. The team is now testing bracelets to monitor users and provide interventions—possibly breathing exercises, brain teasers, or suggestions to take a walk or call a friend.

The Hanford B Reactor, located on the Hanford Site in Washington is a plutonium roduction reactor that was constructed during World War II as part of the Manhattan Project. The plutonium produced in this reactor was used in the first atomic bomb.
The B reactor played a major role in the birth of the atomic age and in the production of nuclear energy. It was designated a National Historic Mechanical Engineering Landmark in 1992.
The land on which the Hanford Site sits was ceded to the United States in 1855 through treaties signed with Yakima and Walla Walla Indians. This area remained unsettled except by Indians through 1860s, except for a trading post and ferry at White Bluffs.
Today there are 79 cultural sites on the Hanford Site, including this 1860's settler's cabin.

In Paraguay, there are a large number of upper limb amputations due to bad working conditions and motorcycle accidents. Many people are also in the low income category, and they cannot afford the prosthesis. With advanced manufacturing, particularly with the use of 3D printing, a company is able to create sophisticated prosthetics at a low cost.
The company, called PO, has combined 3D printing with a control mechanism to make an arm that can perform specific actions. They teamed up with a company called Myo incorporating their armband that controls the mechanical aspect of the hand. Their armband monitors bioelectric muscle signals and interacts with the prosthetic, allowing a user to grip items and gesture as if the arm was part of their body.
Because the company is using 3D printing to build the hands, the cost of the prosthetic is much lower than a traditional one. Incredibly, they can make 100 3D printed hands for the price of one prosthetic. While there is still a cost associated with fittings and the components, much of the price is covered by private donations. The technology behind the project is opensource so that other people can work to make an innovative product that can help people around the world.

Come discover the Town of Stephenville – the natural environment needed to turn a career into an educational adventure!
People and Culture
The Town of Stephenville, located on the north shore of St. George's Bay in southwestern Newfoundland, is 48 degrees north latitude and 58 degrees west longitude. This area was once known as the Acadian Village. From 1848 until 1870, Stephenville was called Indian Head. The name Stephenville was first introduced in 1874. The Acadian Village was a settlement which stretched along the coast from Kippens in the far west to Seal Cove in the far east. This covered a total distance of seven miles.
The Acadian Village consisted of a majority of Roman Catholics who fished and farmed to earn a living. The village was established because of poverty and strife existing in Nova Scotia and the excellent fishing grounds and farm land that western Newfoundland had to offer. Not many details are known about this era.
The Acadian Village was founded in 1844 by two English families. William Hunt and James Penney settled near the Blanche River. They were from Margaree, Cape Breton.
A year later, Felix Gallant and his family arrived. They lived in a hut that had been left by visiting French fishermen. In the same year, on September 3, they had a son and named him Stephen. The following year, they revisited Margaree to have their child baptized. While there, they told their friends about this new "Paradise" where there was exceptionally good arm land and pleasant weather. He persuaded some of his friends to return to Newfoundland with him. Things were hard during the early years of the Town. People did not have enough food or supplies to support themselves. The winter of _PHONE_ was one of the worse that they had experienced. The Gallants and other settlers faced many hardships.
There is still some controversy over how Stephenville got its name. Some believe that Stephen Gallant was the first person born in the area and the town was named after him. However, some believe that Stephen LeBlanc was the first born and that it is after him the town is named.
Since its beginning in May of 1844, Stephenville has grown. The first census report in 1844 cited 103 inhabitants in the area. Today there are over 8,000. Stephenville has grown into an efficient and vibrant community. Today it is the second largest community on Newfoundland's west coast. It provides an exceptional quality of life and has a high level of industrial activity.
Stephenville's past American influence is still very evident in the town. There still remain underground ammunition depots, large airstrips, aircraft hangars and the streets names after American states. Few reminders exist of our past prior to the Americans.
In 1941 the United States obtained rights to construct an air force base in the St. George's Bay area of Newfoundland. The U.S. 76th Congress approved the 99 year lease and in April, 1941, construction began.
The air force base was originally referred to as Stephenville Air Base; however, it was renamed Ernest Harmon Air Force Base in June 23, 1948, in honour of Captain Ernest Emery Harmon. Harmon was a U.S. Army Corps ace who was killed in an air crash in 1933.
On September 1, 1943, the Newfoundland Base Command transferred control of the Harmon Field to the North Atlantic Wing, Air Transport Command. The base became a part of the Northeast Air Command in October, 1950. Then in April of 1957, the Strategic Air Command assumed control.
The mandate of the base was to maintain a tanker alert force and its capability to meet and refuel Strategic Air Command jet bombers on route to targets. The KC-97 was employed in this task. The base was also used as a refuelling stop for transatlantic military flights. In addition, Harmon supported three Air Defence Command units.
In 1957, the Canadian Department of Transportation constructed an air terminal building to accommodate Trans Canada Airlines. 1966 saw the closure of the U.S. Air Force Base in Stephenville. The airport is now owned and operated by a local airport authority.
Stephenville Airport was officially designated as an alternate in the Trans Oceanic Plane Stop (TOPS) program on July 23, 1970. On April 1, 1990, the airport was further designated for alternate use, fuelling only, by international scheduled air transport and for international general aviation regular use.
In recent years, Stephenville has become a favourite technical stop for international flights on route to Europe.
The Town of Stephenville was built on the shores of Bay St. George, with the Table Mountains to the northwest and the Indian Head Range to the east and northeast. The Lewis Hills, the highest elevation on Newfoundland Island at 2672′ above sea level, lie at the coastline of Port au Port Bay about 20 kilometres north.
How to get here
Stephenville is only hours away from eastern North American cities by air. The largest runway in Newfoundland, in excess of 10,000 feet, Stephenville Airport is ideally located and equipped to service both domestic and international flights.
By way of Route 460 or 490, Stephenville is 166 kilometres from the Marine Atlantic ferry terminal in Channel-Port aux Basques. A regular trans-island bus service, DRL Coach Lines, makes regular daily stops in Stephenville.

My gut tells me "investable" with "a" because the definition depends on how much you are able to invest.
The case for "investable" over "investible"
- Merriam Webster's Collegiate Dictionary includes "investable," but not the alternative spelling.
- Garner's Modern American Usage calls "-ible" "dead as a combining form in English," while "-able" is a living suffix that may be added to virtually any verb without an established suffix." It includes "investable" among "some of the hundreds of adjectives preferably spelled -able."
The case for "investible" over "investable"
- Google turns up about 393,000 references to"investible" vs. only 320,000 to "investable."
- Fowler's Modern English Usage says "The –ible form is the natural one for words derived from Latin verbs ending –ere or –ire, making adjectives in –ibilis." I don't know about "making adjectives in –ibilis," but lo and behold, my dictionary says the word "invest" comes from the Latin investire. However, my copy of Fowler's dates back to the 1960s.
- The Financial Times Lexicon goes with "investible." Could this be a British thing?
The SEC is a draw
A search of the SEC website yielded an equal number of results for both spellings. I wonder if they use both as key words for search purposes.
Note: I updated this blog post in 2015 to delete an outdated reference to an inactive poll.

Netflix made the decision to not renew "Warrior Nun" for a third season, and the exact reasons behind it may remain unknown, though it's speculated to be related to money.
As a result, we won't be able to witness the continuation of the intended storyline. However, we can still analyze the first two seasons and their skillful incorporation of historical, religious, and literary references to make educated guesses about what Season 3 would have entailed. By doing so, we can make informed predictions without venturing into pure fan-fiction territory.
In order to achieve this, we will examine the series' religious and historical references, as well as its thematic purpose. It should be noted that "Warrior Nun" speaks to a diverse audience, so any discussion of religious elements will be strictly from a narrative perspective. Furthermore, since the show's strength lies in its skillful incorporation of multiple mythologies and religions without favoring or rejecting any particular belief system, it would be illogical for us to approach this Season 3 projection any differently.
Rather than delving into every obscure clue scattered throughout Simon Barry's series, we will concentrate on those that directly address the show's overarching themes, such as the fundamental nature of truth and faith, and whether they conflict with one another. We will also examine whether there are limitations to the human benefits or viability of truth and faith, and whether faith is a benevolent force that has been perverted by humanity's need for control and oppression, or whether it is a construct born from that same need. Lastly, we will investigate which aspects of these potential truths have been lost, misconstrued, or intentionally manipulated over the course of millennia, and for what purpose.
Will the real Beatrice please stand up in Warrior Nun Season 3?
"Warrior Nun," filled with references, ranging from obvious (such as the episode titles) to more subtle ones. Character names fall into both categories, and while some are self-explanatory (such as Padre Pious Welter), others require closer examination. One such character is Beatrice (played by Kristina Tonteri-Young), a linguistically-gifted and fierce fighter whose name offers numerous potential inspirations.
There is Beatrice of England, who shares similarities with our Beatrice as the daughter of British VIPs. Another potential source is Beatrice Portinari, the unattainable muse of Dante. While the most apparent reference might be Saint Beatrice, the patron saint of prisoners, there is something about Beatrice as a specifically Christian saint that feels a bit too obvious. Instead, we should consider two other Beatrices: Beatrice of Provence, the home of the mythical and fearsome Tarasque (which may sound familiar), and the medieval trobairitz or female troubadour, Bieiris de Romans, also known as Beatriz or Countess Beatrice.
Bieiris de Romans' "Na Maria, pretz e fina valors" has been a topic of debate among scholars for many years due to its overtly romantic language. Despite being written by a woman about another woman, some scholars reject it as an expression of same-sex desire. Some have even tried to deny its female authorship, while others argue that its language is anything but romantic, as per UNC Chapel Hill's "Romance Notes." However, the plot of "Na Maria" seems to connect with Beatrice's love for Ava, and it feels like the missing piece of the puzzle. In the poem, the speaker pleads with Maria not to give her love to a deceitful suitor. As Ava has already given everything, including her life, to a mission that becomes more questionable with each passing episode, the idea of devoting oneself to something "false" seems ready to play out in Season 3.
Beatrice's mandatory un-retirement in Season 3 of Warrior Nun
It's highly likely that in Season 3, Beatrice's journey of self-discovery would be interrupted by an obligatory return to duty. This could be triggered by various events such as a sudden rise in demon activity, a message from Ava's afterlife, an encounter with the Tarask, or news of her sisters and humanity in peril. Although the show typically uses a voiceover recap by Ava to begin new seasons, Season 3 may begin with perspectives from both Beatrice and Lilith, offering insight into their individual experiences.
Lilith, the enigmatic character who has oscillated between being an antagonist and a protagonist in Seasons 1 and 2, presents several possible storylines for Season 3. Her name and the narrative surrounding her thus far provide clues to the directions her character arc could take. The idea of Lilith as Adam's first wife has been a topic of debate for a long time.
She is referred to as the "first" woman in Genesis and is implied to be Adam's equal, but the second woman, Eve, is named and made from Adam's rib, leading to the interpretation that she is subservient to him. To reconcile this contradiction, some early church leaders gave the unnamed woman the name Lilith and portrayed her as too independent, resulting in her being cast out or leaving the garden. This interpretation and its implications will undoubtedly influence Lilith's journey in "Warrior Nun."
Lilith knows something we don't know
The different interpretations of Lilith's story in Genesis, including her being Adam's first wife or a proto-wife cast out of the garden due to her independence, are heavily debated by scholars. While some suggest that the two different women mentioned in the story are the result of different scribes telling the same story, others argue that Lilith has evolved into a feminist icon in modern times, as seen in the Lilith Fair music festival. With this in mind, let's explore how Lilith's past and name might shape her character in Season 3 of "Warrior Nun".
The character of Lilith in "Warrior Nun" is explored in terms of her journey from outcast to feminist icon. In season 3, it is suggested that Lilith will continue to be misunderstood and rejected for her refusal to conform to traditional roles. The show's depiction of female warriors fighting for a male god adds to the ambiguity of their mission. When Adriel (William Miller) asks Lilith what happened to her on the other side, she says she doesn't remember, but her body language says otherwise, thus Lilith is hinted to possess secret knowledge related to the series' overarching plot.
What would Lillth do in Warrior Nun Season 3, though?
"Adriel likes you," Lilith tells Ava in one key moment of Season 2, adding, "that's why he hasn't killed you yet." The statement that Adriel didn't try to kill Ava in "Warrior Nun" Season 2 is incorrect. Lilith is the one who tries to protect Ava and stops Adriel from killing her. Lilith also informs Beatrice about the upcoming holy war, suggesting that she may have obtained secret knowledge during her time in the other realm.
Lilith's actions throughout the series suggest that she has good intentions and is willing to anger those she loves to do what she believes is right. She desires to break free from the control of religious institutions and sees truth and knowledge as sacred. Lilith's actions and beliefs may have been fueled by the desire to provide another option for the oppressed. However, Lilith is not the only character with hidden knowledge.
Semantics return in Season 3 of Warrior Nun
It's possible that Yasmine Amunet, with her Egyptian mother-goddess last name meaning "the hidden one," is the informant who betrayed the OCS to Adriel, given her frequent interference in their affairs despite her charming but seemingly fake incompetence. However, she also exhibits a genuine concern for her newfound family, and her motives, like those of many enigmatic characters in the show, are likely multifaceted and possibly even justified. In any case, it's unlikely that her intentions are intentionally malicious.
One intriguing character in "Warrior Nun" is the first warrior nun, Areala of Cordoba (Guiomar Alonso), whose flashbacks are constantly evolving and unreliable. Despite their manipulation, her story reveals much about her character and past, touching on a central theme of the show: the blurred line between truth and politically-driven revisionism. Areala's narrative is at the crux of this tension, offering clues to significant plot developments in Season 3 that we unfortunately never got to see due to the show's unjust cancellation.
Let's start from the beginning. The flashbacks featuring Areala in "Warrior Nun" are just the tip of the iceberg, given the show's overall tone and subtext. The semantics at play in Ava's interpretation of Areala's history are telling: she fought "in his name" (with emphasis on the "his"), but the identity of this mysterious figure and the cause for which Areala fought remain unclear. Given the stark contrast between the reality of the crusades and the toxic mythology surrounding them, it's unlikely that the show's ancestral hero figure would have blindly accepted Pope Urban II's hateful propaganda or supported politically-motivated violence.
And Areala returns, as well
A crucial detail in the first Areala flashback is that she and her knights approach Almodóvar Castle, situated near Córdoba. This suggests that Areala's narrative is rooted not in the crusades in Jerusalem, but in the intricate and diverse history of the Iberian Peninsula during the 11th century.
It would be impossible to summarize the intricacies of centuries-long political and cultural conflicts and collaborations, but one thing is clear: if Areala had grown up in or near Córdoba, she would have witnessed firsthand the effects of religious tolerance on the


The Cosmos of Arthur Holly Compton: The public papers, both scientific and humanistic, addressed to his fellow citizens by one of this century's most distinguished physicists and philosophers of science. Edited by Marjorie Johnson, hardcover, very good condition
Arthur Holly Compton (September 10, 1892 – March 15, 1962) was an American physicist who won the Nobel Prize in Physics in 1927 for his 1923 discovery of the Compton effect, which demonstrated the particle nature of electromagnetic radiation. It was a sensational discovery at the time: the wave nature of light had been well-demonstrated, but the idea that light had both wave and particle properties was not easily accepted. He is also known for his leadership of the Manhattan Project's Metallurgical Laboratory at the University of Chicago, and served as Chancellor of Washington University in St. Louis from 1945 to 1953.

The Physiological, Psychological Foundation and Advantage of Mental Arithmetic by Image of Zhusuan
Mental Arithmetic by image of Zhusuan is a calculation method by relying on the function of human's brain an utilizing object image of abacus beads in brain through sense perception, imagination and memory, imitating Zhusuan method to complete changing pattern of numbers in mind. It is on the basis of Zhusuan, from Zhusuan and over Zhusuan. It is a development of Zhusuan. Therefore, the development of mental arithmetic by image of Zhusuan is a new pass for further development of Zhusuan. Through the following brief description of physiology and psychology, we can search out the unique adaptability and advantage of mental arithmetic by image of Zhusuan.
The human anatomy tells us that human's brain can be divided into six parts : cerebrum, cerebrum in between, cerebellum, center cerebrum, bridge cerebrum and medulla oblongata. Centre cerebrum, bridge cerebrum and medulla oblongata are usually called cerebrum trund. Cerebrum is the most complicated part in nervous system and is the organ for psychology activities.
Human's cerebrum is divided into left and right hemisphere. The research of psychology indicates that the shape of the two hemispheres is similar but the function is different. The left hemisphere has close relation with language ability and thinking activities and has the function of language, abstract though and logical reasoning. The right hemisphere is concerned with object thinking such as image and shape and has the function of model identification, shape sense, creative thought and intuition. Most people consider that the function of left hemisphere is dominant and the right hemisphere is not. The physiologists and psychologists generally consider that the potential of human's right hemisphere needs to be exploited. The ideal method is to identically use the two hemispheres, let left hemisphere co-ordinate with the right hemisphere or let the right hemisphere influence the left hemisphere to make the two hemispheres coordinating each other.
By understanding the work division of the two hemisphere, we can better use and practice our brain. People always thought in the past that by improving the ability of language and reasoning, other abilities can be improved at same time. It seems at present that thinking is lopsided. Human must overally develop cerebrum, both left cerebrum and right cerebrum in order to continuously improve the capability of creation and nonlanguage thinking.
The psychology considers that there are two informations stored in human's brain, i. e. figure and language. The figure is objective image and termed as idea by psychology. It has not only the characteristic of intuitivity and generality but also operability. This operability means idea can be arbitrarily rotated and changed, processing for ides. It is the operability of idea which makes image of Zhusuan is completed with image thinking guided by logical thinking. Its' figure in brain is the abacus beads. It is the operability of idea which makes plus and minus of abacus beads being operable and calculation in brain. Meanwhile, it promotes the exploitation of the right half of cerebrum.
Functionally speaking, human psychological activity can be divided into activities of perception, emotion and will. Seen from the generated mechanism, it's a function of brain and a reflection of objective reality. Perception activity means phenomenons shown during human perceiving objective things, including sense perception, consciousness, memory and thought, etc.
1. Sense perception
Sense perception is a brain reflection of individual characters of objective things which directly function in sense organs. It's also a result of united activity of combined analyzers which are composed of three areas respectively corresponding to sense organs, in-transferring nerve and cerebral cortex. Sense perception is a subjective image of objective world, on one hand, it's generated from subject, on the other hand, it's reflection of objective existence. Sense perception can be divided into outer and inner perceptions, outer perception reflects individual characters of objective things, its receptor is on or near the surface of body. For instance, visual analyzer or receptor is retina, audio receptor is in inner ear. This kind of sense perception consists of visual sense, hearing sense and touching sense, etc.
For mental arithmetic by image of Zhusuan, its objective things are numerals and abacus beads, it's reception modes are reading calculation and glancing calculation, i. e. oral reading and visual glancing. The two modes respectively act on sense organs, through visual or hearing sense, passing on to relevant areas of cerebral cortex, changing static beads to moving beads, and reflecting processing and calculation of value assigned beads in brain.
Memory is mental reflection of past experience, and it's one of the important functions of brain. It includes the following basic processes: identification, retention, re-identification (or re-perception) and reappearance (or memory), etc. These basic processes are interrelated. Identification and retention are the premise of re-identification and reappearance, while re-identification and reappearance are the result of identification and retention. Memory is a basic functional index, being a treasure house of human knowledge and experience. It's of great significance in practical life. Only with memory, can experience be accumulated and expanded, can get previous and subsequent experiences related, and make psychological activity nor intellectual activity is possible. The image of objective things retained in memory is called memory ideas, or idea for short. The accumulation and enrichment of idea plays an important role on human activity of thinking, imagining, remembering as well as the process of mental arithmetic by image of Zhusuan.
It is common that people usually think human memory and intelligence begin to decline after the age of 20. One of the reasons is based on the fact that neuron (cranial nerve cell) dies at the rate of 1,000 per day and cannot revive. It's discovered by physiological research on memory that human memory capability is infinite. Human brain is composed if 10 to 14 billion neurons, even of 1,000 neurons die every day, the neuron loss during one's life is less than 1% of the total number, so the influence on memory is negligible. In physiologists' point of view, the more frequently brain is used, the more developed, intelligent and healthy brain becomes; on the contrary, if brain is not or seldom used, its aging and declining will be accelerated, Therefore, the relation among memory, intelligence and age is not absolute.
Thinking, which is the general, indirect reflection of objective things, belongs to advanced stage of perception. Thought is generated on perceptual knowledge, which is the source and basis of thinking activity. Through thinking, human perceptual knowledge of concrete objective things is ascended to rational knowledge, then concept is generated, and concept's application analysis, generalization, inference and judgement gives rise to theoretical system.
Thinking of mental arithmetic by image of Zhusuan is generated from perception of numeral combination, its form is similar to that of abacus type. Zhusuan psychologists think that Zhusuan thinking is realized through four stages : reception, selection, identification and instruction. What's different is that the instruction of Zhusuan thinking is transformed from imagination on third stage, then the instruction is passed to behavior organ, so creative behavior is realized by moving up and down the beads in brain. But the mental arithmetic by image of Zhusuan is utilizing the image in the mind, changes static beads to moving beads, and reflects the operation and calculation result of beads.
To sum up, mental arithmetic by image of Zhusuan is realized by sense perception (hearing and visual sense), memory and other directly sense-perceived images, as well as thought in images under the instruction of logical thought, it has not only uniqueness different from other mental arithmetic, but also adaptability to physiological mechanism and psychological activity.
Some people have a point of view that to learn and apply mental arithmetic by image of Zhusuan is only suitable for teenagers. The more above this age, the more difficult to learn. Certainly, teenagers are at their best ages to receive training of mental arithmetic by image of Zhusuan. Due to various factors, the training is not so effective for adults. But just as above mentioned, there is no absolute relationship among memory, intelligence and age, learning and applying mental arithmetic by image of Zhusuan should not be limited by ages.
Based on the above physiology and psychology analysis, we can see that mental arithmetic by image of Zhusuan reflects both adaptability and the following main incomparable advantages over other mental arithmetic:
Since calculation works are important in every sections of social economic area, so the more developed the economy, the more important the calculation work is. Along with the establishment and development of market economy, calculation techniques, especially mental arithmetic, are increasingly important to more and more people in order to meet the needs for production, circulation and all calculations in our life.
Mental Arithmetic by image of Zhusuan is an important part of calculation work, it features quick calculation, high accuracy, good adaptability, wide spread application, little limitation, so it has extensive practicality. As long as having certain Zhusuan basis, mastering the Zhusuan characteristics and practicing hardly, one can master the mental arithmetic with high proficiency, so working and studying efficiency can be improved.
Cerebrum has huge potentiality. Encephala experts believe that only 5 to 15% of cerebrum functions have been utiliazed. Even Einstein, the great scientist, had only used 1/3 of his cerebrum. That is to say, 85 to 95% of potentiality of cerebrum have not been utilized. So how to cultivate and utilize potentiality of cerebrum is becoming more important. Right cerebrum is key to

The integration of microgas turbines (MGT) and absorption chillers is an emerging technology that uses a wide range of fuels to produce electricity, cooling and heating simultaneously for small scale distributed generation in grid connected or isolated locations. This paper studies the performance of MGTs of different power capacities directly coupled to double-effect water–LiBr absorption chillers. In these systems the MGT exhaust gas is the heating medium to drive the chiller. Also post-combustion natural gas is used to increase the cooling capacity of the system. The paper analyses the effect of the post-combustion degree on the integrated system performance of four MGT power sizes. Two cases are considered. In the first, fresh air is added together with the post-combustion natural gas and in the second it is not added. In the latter case the oxygen necessary for the combustion reaction is extracted from the MGT exhaust gas stream. For the sake of comparison a study is also made of the performance of a more conventional system consisting of an MGT and a hot water heat exchanger to drive an absorption chiller. The main advantages of the new technology over this conventional system are that the COP of the chillers is higher because they are driven by higher temperatures, the production of electricity and chilled water is decoupled and there is a wider range of chilled water production capacity.
The new distributed generation equipment coming onto commercial and industrial markets provides waste heat that can be applied to absorption cooling. This significantly increases overall system efficiencies. On the other hand, expanding power demands, increasingly restrictive environmental regulations and the deregulation of the electricity market are providing an opportunity for developing these new on-site distributed generation technologies such as microgas turbines (MGT). MGT technology can be integrated in distributed power generation systems to produce electricity, heating and cooling simultaneously for air conditioning and industrial applications although such uses as vehicle propulsion are also currently under development. The main advantages that they have over other competing technologies are the fuel flexibility, low emissions, quiet operation and low maintenance and. The electrical efficiency of the current regenerative MGTs, which are also characterised also by low pressure ratios and modest turbine inlet temperatures, is in the range of 25–30% depending on the MGT size. Thus if the overall system efficiency is to be competitive the waste heat available in the MGT exhaust gas must be effectively recovered. In warm climates such as the Mediterranean where there can be long hot periods, so-called trigeneration systems (power, hot and chilled water) are a better alternative than the simple cogeneration system for producing only power and heat. Absorption refrigeration systems can be used in combination with MGT to recover MGT waste heat so that chilled water can be produced and the electric load demanded by the more conventional compression refrigeration systems reduced or eliminated. Nowadays the only commercially mature technology for cooling using absorption chillers for small power applications in combination with MGT is the one using an intermediate gas/water heat exchanger that produces hot water to drive the absorption system. Because of the low temperatures, only single-effect absorption chillers can be used. So the existing MGT/absorption systems are too limited: their COPs are too low, the range of chilling capacities are not wide enough, and electricity and cooling capacity depend completely on each other, etc. For these reasons it was decided to analyse the possibility of using the exhaust gas in direct fired absorption machines with the option of natural gas post-combustion. Direct-fired chillers are more efficient and better positioned in the refrigeration market than their hot water driven counterparts. Some research projects are being carried out into direct MGT exhaust gas fired absorption systems although not all of them use cofiring. The most well known are the CEEE project at the University of Maryland, Southern California Gas Co., Takuma/Capstone and Ingersoll–Rand/Hussman all in the USA, the University of Pisa project in Italy and the Icogen S.A. development in Spain. Some new small ammonia/water generator–absorber heat exchange (GAX) chillers are promising because they can be driven directly by exhaust gas and do not require a cooling tower. These GAX systems are entering the market now (2004). The objective of this paper is to study the integration of MGTs and double-effect direct-fired absorption systems. The exhaust gases from the MGT are directed to the absorption chiller with the option of additional natural gas post-combustion. Two cases are considered. In the first, fresh air is added together with the post-combustion natural gas. In the second, fresh air is not added and the oxygen necessary for the combustion reaction is extracted from the MGT exhaust gas stream. A comparison is made with a similar system that uses a hot-water driven absorption system. Before the modelling characteristics and the results are presented, the current technology in MGT and absorption cooling suitable for MGT/absorption refrigeration coupling will be briefly reviewed. Also the special features of the various MGT/absorption refrigeration integrated systems will be presented.
نتیجه گیری انگلیسی
The main advantages of a directly driven absorption chiller with a post-combustion system over the more conventional single-effect hot-water driven system are a higher COP, a decoupling between electricity and chilled water production and a wider range of chilled water production capacity. Two directly fired cases have been studied: in one case extra fresh air was added for post-combustion and in the other it was not. With additional fresh air, the cooling capacity of a directly fired double-effect chiller integrated in an MGT with an electric power capacity between 30 and 100 kWe increases from 500 to more than 1600 kW depending on the MGT size and the degree of post-combustion. In the MGT/absorption chiller system with post-combustion and fresh air there is an optimum amount of post-combustion represented by a PCF ratio of about 0.25 that produces the optimum global operation point of the system. This means that at this ratio value, the operational costs will be lowest. This point of maximum efficiency exactly matches the maximum temperature of the gases entering the chiller. As the amount of post-combustion natural gas increases so does the cooling capacity but the fresh air required for cofiring also increases and dilutes the heat provided by the gases coming from the MGT. For this reason the cooling power decreases after a certain optimum value of post-combustion is exceeded. When no additional fresh air is added for the post-combustion, the MGT exhaust gas is directly used as combustion air. In this case, the amount of post-combustion natural gas is limited by the maximum temperature that the post-combustion chamber can withstand, not by the oxygen content in the MGT exhaust gas. The maximum cooling capacity in this case is lower than when additional fresh air is used. Below this maximum point, the cooling capacities with and without additional air are not very different but higher when fresh air is added.

Editor's note: On Jan. 19, 2012, the pharmaceutical companies AstraZeneca and Bristol-Myers Squibb announced that the FDA rejected their approval request for dapagliflozin, calling for more research data on the drug's benefits and risks. Both companies say they remain committed to developing the drug and will work with the FDA to determine the next steps.
July 19, 2011 -- In a 9-6 vote, an advisory panel said the FDA should not yet approve dapagliflozin, a new type of diabetes drug that makes the body dump sugar and lose weight.
Signals of possible liver damage and of breast and bladder cancer worried the experts.
The split vote, as well as panelist comments, makes it uncertain whether the FDA will approve the drug, jointly made by Bristol-Myers Squibb and AstraZeneca. The FDA will certainly ask the companies to gather more data on side effects; the key question is whether the agency will ask for this data before or after approval.
Dapagliflozin is the first in a new class of diabetes drugs. Normally, the kidney recycles sugar back into the body. But dapagliflozin inhibits a transporter molecule called SGLT-2. The result: Sugar passes out of the body in the urine, lowering blood sugar without affecting insulin levels.
Another result: Patients lose weight. In clinical trials, type 2 diabetes patients who took dapagliflozin for six months lost 1 to 5 pounds. In a special study to look at weight loss in people with diabetes, 30% of those who took dapagliflozin plus metformin lost 5% of their body weight.
A downside to the drug is that diabetes often damages the kidneys. Even moderate loss of kidney function makes dapagliflozin much less effective. The drug would be given only to patients with sufficient kidney function, but some panelists questioned the value of a proposed test to determine which patients could take dapagliflozin.
And the drug has side effects. All that sugar in the urine increases patients' risk of urinary tract and genital infections. There are other worries, too -- including dehydration and heat intolerance -- but members of the advisory committee were far less worried about these side effects than about the possible risk of cancer and liver toxicity.
In clinical trials, nearly 4,300 people with type 2 diabetes received dapagliflozin for over a year; 441 patients were treated for at least two years.
In these trials, five patients showed signs of liver toxicity. Only in one case was this liver toxicity classified as "probable diagnosis of mild to moderately severe dapagliflozin-induced liver injury." But such a strong signal, even in a single patient, is worrisome.
Nine patients taking dapagliflozin developed bladder cancer; only one case was seen in those not taking dapagliflozin. Nine other patients taking dapagliflozin developed breast cancer. There were no breast cancers in those not taking dapagliflozin.
That's by no means proof that the drug causes cancer. But definitive studies might require thousands of patients. The question now before the FDA is whether the modest blood-sugar-lowering and weight-reducing benefits of dapagliflozin are worth the risk.

- SetFree[dropcon, options] builds a FreeSystem object containing the mathematical equations required to find equilibrium conditions of the current model. The dropcon argument is used to specify the constraint(s) that are dropped to make the system underconstrained.
- The format of dropcon is identical to that used by the Constraints function.
- The FreeSystem object is solved with SolveFree.
- The following options can be given:
- If InitialGuess or InitialCondition is unspecified, SetFree uses the current model initial guesses, as obtained from LastSolve.
- InitialCondition can also be specified in SolveFree.
- If Solution->Static is given, the model must have some nonzero applied loads for a static equilibrium position to exist.
- If Solution->Kinematic is given, the model must have velocity-dependent loads applied, or no equilibrium velocity can exist.
- If Solution->Dynamic is given, the model must have nonzero masses applied to at least one moving body with SetBodies.
- See also: SetCouple.
Load the Modeler2D package and define a simple model.
Here we build a FreeSystem object that can be used to simulate the underconstrained motion of the help model when the constraint that controls the rotation of the crank has been removed. Before calling SetFree, a velocity solution is generated with SolveMech so that initial conditions for the location and velocity of each body will be available.
Because the help model has only one body with nonzero mass and one applied load (the link body has a 10-unit mass and a 10-unit applied load in the X direction), the instantaneous free acceleration is somewhat predictable. The X acceleration of the link body, X3dd, is equal to 1.0.
Here we integrate the free acceleration of the help model with respect to time for four seconds.
Here is a plot of the X position of the link. The link is initially decelerating until its X coordinate reaches a local minimum, and then it accelerates the other way.

U v02 biotinadapter 21++.json
In addition to our structural considerations we also did computer simulations on our structures. They were performed with canDo (a finite elements simulation based on our *.json files and mechanical properties of dsDNA). Figures 7a and b show the simulation of the nontwisted structure from two views. In comparison figures 8 a and b show the pre-twisted structure from the same projections. One can clearly see the twist and spread of the arms in fig. 8 a,b. These simulations were used for further theoretical and experimental considerations.
Survey of Folded Structures
For a detailed list of all structures, please consult the labbook entry.
One of the most important structures for this project was BM2, which is a simple U shaped origami as described above. Most of the TEM analyses concentrated on this structure.
Other important structures were BM12, BM13 and BM14, which contain FRET labels for twist measurements at positions that will later be explained in detail. Each of these structures additionally contained several adapter staples at the bottom, which could be used for immobilization via biotin / neutravidin. These structures are suited for single molecule fluorescence microscopic examination.
BM21 is designed very similar, but with FRET labels positioned for length measurement instead of twist. Finally, BM24 (unlabeled) and BM25 (labels for twist analysis) are intrinsically twisted reference structures.
Twist of the Arms
Fig. 9 Cylindric model for the twist of the arms.
The origin of z is located at the bottoms of the arms where the base ends as depicted in the figure 9 to the left. The angle α of the torsion of the arms shows a linear dependency on z α0 defines a position in the undeformed state, Δα + α0 is the maximum torsion at the end of the arms, B is the length of the base and L is the total length of the structure):
The distance between two points on the mantle of the cylinders that describe the arms can be easily derived by vector analysis and results in:
The following diagram (fig. 10) shows a relation between Δα and d for R=4nm, D=13nm and α0=0°.
Fig. 10 Distance between two points on the cylinder mantles representing the arms over torsion angle Δα.
Observing TEM Pictures
In TEM images a dark line can be observed between the two six helix buldles of each arm. If the arms are twisted, this line is no longer exactly in the middle of one arm but "moves around" it. There should also be a variation in the visualized width of the arms due to the asymetric cross-sectional area.
Fig. 11a Top view of BM2 without DNA-binders.
Fig. 11b Top view of BM2 with approximately one EtBr molecule every 7bp.
Twist of the Base
Fig. 12 Cylindric model for the twist of the base.
To transform the measured arm-twist into a deformation of the structure's base one can assume theU as three cylinders of the same radius. Two of length L (the arms) and one of length B (the middle part of the base). To describe the deformation another cylinder of radius R = radius of the base-cylinder + radius of one arm cylinder and length B is constructed in a way that the center-lines of both arm cylinders are located on its mantle. The torsion of this cylinder (shown in red on the image above) can be directly related to the arm twist.
α describes the torsion and is divided into α = β + γ to include the different projections of the structure on the grid within the theory. The angle 2δ between the arms is related to an angle φ due to an easier measurement (tree characteristic points are defined as shown in the following figure 13, one in the middle of the end of the base and one in the middle of the end of each arm).
Fig. 13 Representative TEM image including the way φ is measured.
The correlation between δ and α including the different projections described by β is:
The following equation is the arithmetic average of L(sinβ + sin(α − β)) − Bsinβ for 0 < β < α:
This equation relates α and φ for an average projection.
Fig. 14 The measured angles φ over the torsion angles α.
This graph (fig. 14) shows the result plotted for radius R=6 nm, base length B=35 nm and total length L=98 nm. For this calculation φ was calculated for α from 0 to 133° because of the maximum of ε at this angle. It can be shown in TEM images that the maximum torsion is below this maximum angle α by observing the change of the base width. The maximum change refers to a torsion of 180° and can easily be recognized by thinner base. However, none of the structures examined show a big change of base width.
Observing TEM Pictures
The twist of the base can be observed at structures that are shown from the side. The twist of the base (in this case the middle part of the base) can be related to a speading of the arms. The following picture (fig. 15) shows a structure in a control measurement of BM2 without DNA binders on the left and a twisted structure of the reference BM24 that is designed as a twisted structure on the right.
Fig. 15a Side view of BM2 without DNA-binders.
Fig. 15b Side view of BM2 with one EtBr molecule every 7bp.
The calculations of the base twist result in a modified D for the arm twist. Focusing on the base twist theory the distance between two points on the center lines of the arm cylinders can be described by:
Now the arm twist theory can be applied using D(z) instead of the fix value D:
The angles for base and arm twist can be normalized to α as an angle per length:. RB is half the distance between the center lines of the arms at the base and RA is the distance of the cylinder center to a point on the cylinder mantle in x-y-direction.
Fig. 16a & 16b correspond to FRET-pair positions C1→C2 as described in the article about FRET-pair positions and to the structure BM14_5/20.
The parameters describing the FRET-pair position are:
- RA = 3.5nm
- RB = 6nm
- α0 = ±17° (+ for counterclockwise, - for clockwise)
- z = 55nm
- B = 35nm.
For a Förster-radius R0 = 6.5nm a maximum distance
can be evaluated. This corresponds to a maximum angle of 1° per nm or a maximum torsion of 35° over the length of the base and 55° over the rest of the arms for counterclockwise torsion and 1.4° per nm for clockwise torsion.
Thermal Fluctuation of the Arms
In order to estimate the width of the broad spread of the data points around the mean angle from the TEM angle measurements, we calculated the width of a Boltzmann distributed fluctuation of the arms. Hereby we assumed the DNA helices to be cylinders with a certain stretch modulus E, persistence length p and to fluctuate independently.
Within these measurements we always quantified the angle between the end points of the arms and the other end (at the base).
Fluctuation of One Arm
The probability of finding a rod with a 10 helix bundle cross section at a certain angle φ
is given by a Boltzmann distribution
where the energy is given by
with r the radius of curvature, L the contour length of the arms and I10 hb the area moment of inertia of a 10 helix bundle.
If we assume a constant curvature of the arms, the radius of curvature can be translated in an angle φ (see Fig. 18).
Fig. 18 Fluctuation angle φ.
The area moment of inertia of a rod is given by
Now we're able to calculate the area moment of inertia of the 10 helix bundle with the parallel axis theorem (see Fig. 19).
Fig. 19: Cross section of one of the 10 helix bundle arms. The distances for the parallel axis theorem and the direction of the fluctuation we are looking at are indicated in red.
and therefore the energy needed to bend one arm by the angle φ
as well as the probability.
Fluctuation of the Measured Angles
Since the fluctuation of the arms is stochastically independent, we have to take the convolution of the two probabilities:
with Δφ = φ2 − φ1
With all this follows
Therefore we get a standard deviation of the measured angles of
Double stranded DNA has a persistence length of about and the arms of the U have a length of about (predicted by the json file). This gives us a width of the distribution of about
Experimental Considerations for FRET
Fig. 20 FRET efficiency over the torsion α
Certain combinations of dyes exhibit a phenomenon called Förster Resonance Energy Transfer (FRET) when in close proximity. For this to happen, their spectra must match so that the emission of the one dye can excite the other. In short, this means that if the dye with shorter excitation wavelength is excited, it can transfer its energy onto the other dye with the longer excitation wavelength in a radiationless fashion resulting in a shift of emission to longer wavelengths. The extent to which it happens is called FRET efficiency EFRETand is a sharply

In the first lines of "Mind," the speaker offers a metaphor for the mind, comparing it to "the slow overture of rain." Overture in this context denotes an orchestral introduction to a musical dramatic work. The speaker compares the way the mind moves from one perception to the next, one thought to the next, with the way an overture leads into the musical work itself. The mind is "unrelenting" because it never stops. It is "syncopated" (also a musical term) because, as in an overture, there is a shift to something else, maybe another perception, another subject, or another way of thinking. These lines comment both on the workings of the mind and the workings of this poem, which also shifts subjects.

Lines 7–13
The speaker continues comparing the mind with natural phenomena. The speaker imagines that the hummingbird and the swallow perceive the world in ways that make sense to them. The hummingbird, for example, mistakes its wings for its heart because its wings are its most strategic asset. Hummingbirds flap their wings from fifty to two hundred times per second and can lift from perches without pushing off. Swallows, which dip and dive dramatically, could easily confuse how the horizon appears to them in flight for what they are doing to it (i.e., lifting and dropping it). This connection between the birds' misunderstanding of the world and themselves and the human mind suggests that human beings also delude themselves into thinking they know what is real and what is imaginary. When the speaker asks, "What is it / they cast for?," she anthropomorphizes them. This means that she projects onto them human attributes, in particular the attribute of desire. "Casting" suggests fishing, a familiar enough activity for birds.
Lines 14–19
The speaker continues her comparisons, noting the swallows' perception of poplars, quickgrowing trees of the willow family found in North America. The speaker describes how their appearance changes depending on the swallows' perception of them. In describing them as "making arrangements," the speaker personifies them, just as she had the swallows and hummingbirds. "Arrangement" is also a musical term meaning an adaptation of a musical composition by rescoring.
Lines 20–24
The speaker reverses the subject and object of perception. Whereas in the previous descriptions she shows how birds perceive the physical world, in this description she positions the city as the subject drawing "the mind in streets." This reversal gives credit to the phenomenal, material world in constructing reality. The streets "compel" the mind "from their intersections," meaning from where lines connect. The relationship between subject and object, perceiver and perceived, dissolves here.
Lines 25–28
The speaker depicts the mind as an active force that is nonetheless "driven" (though by what readers are not told). These lines are typical of the heavily abstract statements for which Graham is known, statements that are difficult to translate or paraphrase. Gravity has a stake in "all stationary portions / of the world." These "portions" are stationary because gravity keeps them that way (unlike, for example, hummingbirds or swallows, which can defy gravity with their ability to fly).
Lines 29–35
The speaker uses the symbolic image of leaves in the November soil to suggest decay and fragmentation. When the "edges give a bit / and soften" they lose their definition and become part of their environment. This blurring of a thing (i.e., leaves) with the larger body to which it belongs (i.e., soil) echoes the way in which the mind also blurs as it changes from subject to subject, perception to perception.
Lines 36–39
The speaker implicitly compares the leaves to the mind, suggesting that in time both fragment and come to rest in the ground, where they are "all the richer for it." This last image suggests a picture of a compost heap where the leaves return to the soil from which they came, and the mind returns to a state in which it no longer differentiates the particularities of the physical world, and is no longer aware of itself as a perceiving entity.
