Hyperfine-assisted fast electric control of dopant nuclear spins in semiconductors
Nuclear spins of dopant atoms in semiconductors are promising candidates as quantum bits, due to the long lifetime of their quantum states. Conventionally, coherent control of nuclear spins is done using ac magnetic fields. Using the example of a phosphorus atom in silicon, we theoretically demonstrate that hyperfine interaction can enhance the speed of magnetic control. Based on that result, we show that hyperfine interaction also provides a means to control the nuclear spin efficiently using an ac electric field, in the presence of intrinsic or artifical spin-orbit interaction. The electric control scheme we describe is especially fast in a hybrid dot-donor system subject to an inhomogeneous magnetic field.

Restoring a Free-Flowing River in Cuyahoga Falls
As part of an initiative to remove abandoned dam structures and restore free-flowing river conditions along the Cuyahoga River from Lake Rockwell to Lake Erie, the Ohio EPA worked with GPD to develop a comprehensive plan.
The project removed two 100-year-old dams in the city of Cuyahoga Falls, while stabilizing adjacent remnant powerhouse structures. GPD's design team evaluated the change in hydraulic forces and designed a system to maintain structural stability. The physical removal of the dam structures posed unknown challenges associated with exposed riverbed within the limits of eliminated dam pool. Design concepts for structure and bank stabilization methods remained subject to modification as each area became exposed during the construction phase, thus exercising a true design-build team effort.
This successful project restored portions of the Cuyahoga River with no impact to adjacent structures. The waterway achieved free-flowing conditions, meeting EPA objectives for improved water quality and also providing safe passage for a water trail and recreational benefit.

text: Giant Funupolope is similar to snails on Earth. It has a hard shell, no legs and it uses slime to move. They are the size of a small Pug. They feed off of jungle biome leaves, ferns and bone to make their shell. They live in the jungle biome. They are hermaphrodites, both female and male. It is for the same reason snails are hermaphrodites on earth, they are not very fast moving.

The uncertainties of power systems are becoming more and more important due to power systems restructuring and ever increasing renewable generation integration into the grid. In the literature several uncertainty modeling approaches have been proposed to facilitate decision making process for efficient operation of power systems. These approaches mainly focus on deriving a statistical representation for different sources of uncertainty such as load, generation, and line capacities. However, there is a need for an uncertainty model which can capture the frequency components of uncertainty signals for applications such as voltage control, frequency control/ stability, and grid vulnerability analysis. In this paper we proposed an uncertainty modeling approach that captures the high dynamics of renewable generation uncertainty and smart grid loads and reveals their frequency domain characteristics. We tested the proposed model on IEEE 300 bus system to evaluate the impact of uncertainty on line flows.

Frank Lloyd Wright is possibly the most prolific and revered architect in all of American history. He pioneered revolutionary techniques and styles that are replicated countless times across the American architectural landscape. But did Wright build homes in location-efficient places? Today we will explore two of his most well-known works: The Fallingwater House in Stewart Township, Pennsylvania, and the Robie House in the Hyde Park neighborhood of Chicago.
Today these structures are museums rather than anyone's home, but we were still curious to see what a typical family living there would pay for transportation. We at Abogo wouldn't mind living in what must feel like a tree house. But what happens when we eventually have to step outside to work, shop, or meet up with friends? What kind of transportation costs would a typical family living in Fallingwater encounter?
The Fallingwater House, finished in 1937, is a revolutionary piece of organic architecture that integrates the structure of a man-made building with the brilliant resonance of its natural surroundings.
Architectural lore is that Wright designed the house in one sitting of less than three hours, which is remarkable given the international accreditation it has since received. Let's take a look at the current monthly transportation costs a resident could expect.
Given an average gas price in the region of $3.50/gallon, transportation costs would average nearly $1,250/month. That's more than a 20 percent increase in the cost in 2000.
This high monthly average is due to a number of factors, stemming from its location. The Fallingwater House was built as a rural weekend retreat, and to this day it remains in a very rural area. Stewart Township has a population density of only about 15 people per square mile and does not have public transit for the region. Walking and biking are certainly pleasant given the spectacular scenery; however, the nearest grocery store is over six miles away. Residents of Fallingwater and their neighbors may want to invest in fuel-efficient cars to keep transportation costs as low as possible.
The Robie House is a similarly revered work, completed by Wright in 1910. Located right next to the University of Chicago, it is a prime example of the Prairie Style of architecture. However, the building has faced the threat of demolition multiple times. One was so serious that a 90-year-old Wright visited the site to protest. Thankfully it is now a Chicago Landmark, which protects the building from demolition, and the Frank Lloyd Wright Preservation Trust maintains the building.
Let's take a look at the transportation costs one could expect living in the Robie House.
Despite higher gas prices in Chicago, $794/month in transportation costs is markedly better than the cost of getting around if you lived in Fallingwater. The increase in transportation costs for Robie House over the past decade is a relatively modest 14 percent.
Chicago has a population density of 11,864 people per square mile, which provides both the resources and incentives for efficient public transit options. A 30-day pass on the CTA, which will take you anywhere in Chicago and even Evanston to the north, is only $86. Likewise, there are many businesses and amenities within a short distance, making walking and biking to destinations much more feasible. Having options other than the car makes average transportation costs less reliant on gas prices, keeping the average more stable over time.
What's your favorite Frank Lloyd Wright home? Do you think transportation costs there are more similar to Fallingwater House or Robie House? Plug the address into Abogo and let us know what you find out!

Bees were conditioned to collect food on natural and artificial flower beds, parts of which could be set into rotation or side to side movement. Through the relative motion of the flowers the number of alternating stimuli upon the bee's eye is increased. Due to the fact that bees show a strong reaction to intermittent optical stimulation, the proportion of bees settling on the moving section of the flower bed is increased. It seems probable therefore that the visual reaction of bees to flowers in nature is largely due to the flicker effect produced through the motion of the bees relative to the flowers.

Why and When to Use a Stereo Mic on a Camera
A typical human being sees the world through two eyes, smells the world through two nostrils, and hears the world through two ears. Why we only have one mouth is a mystery, but it likely has something to do with noise pollution. Since we hear the world through two separate ears, recording audio in stereo for video work seems like a natural choice, but it isn't always the best choice. Even so, there are many situations where using a stereo mic on a camera yields really nice results. In this article I'll tell you about the times when you should use a stereo mic on a video camera, and make it clear when you should use a different kind of microphone. Plus I'll share some mission critical tips for getting good sound when shooting outdoors.

Weather of Arabia - California has been exposed for quite some time to a series of severe weather disturbances, the most recent of which was during the past days, as snow fell heavily in many parts of the state until it affected coastal areas, meaning that the snow fell at sea level, and this indicates the strength of the snow storm that The state was exposed to it, and after the snow melted and the precipitation turned from snowy to rainy in the low-lying areas, torrential rains formed in many areas and rivers overflowed as a result of carrying more water than their supposed absorptive capacity.
According to the outputs of the numerical models, it is expected that heavy rain will continue in many areas on Sunday and Monday, with snow falling over the high mountain heights in the state.
A rainstorm hits the state on Tuesday and more torrential rain
The outputs of the numerical models in the Arab Regional Weather Center indicate the formation of an air depression over the mid-ocean waters, moving eagerly over the ocean waters as it gains sufficient moisture that may lead to its development of a winter storm threatening the state of California on Tuesday.
Heavy rains are expected in the state, accompanied by strong winds and strong waves, and heavy snow is expected on the high mountain heights in the state.
In light of the saturation of the land with water, it is not excluded that torrential rains will form and the occurrence of landslides and soil erosion as a result of heavy rains.

We present a novel approach to solving Quantified Boolean Formulas (QBF) that combines a search-based QBF solver with machine learning techniques. We show how classification methods can be used to predict run-times and to choose optimal heuristics both within a portfolio-based, and within a dynamic, online approach. In the dynamic method variables are set to a truth value according to a scheme that tries to maximize the probability of successfully solving the remaining sub-problem efficiently. Since each variable assignment can drastically change the problem-structure, new heuristics are chosen dynamically, and a classifier is used online to predict the usefulness of each heuristic. Experimental results on a large corpus of example problems show the usefulness of our approach in terms of run-time as well as the ability to solve previously unsolved problem instances.

Social Policy and Sustainability
While welfare states and associated social policies have been successful in addressing social risks associated with the provision of capitalist growth and increasing their citizens' wellbeing, they have also contributed to climate emergency and the ecological crisis. We carry out social-policy research of traditional themes such as labour markets, inequality or poverty, but also and particularly in the new circumstances of climate emergency.
Considering different scales from the local to the EU level, we (co-)develop relevant theoretical concepts such as 'sustainable welfare' and 'degrowth/postgrowth', conduct corresponding empirical research - for example into attitudes towards sustainable welfare and alternative forms of political mobilization. We also identify 'eco-social' policies capable of reembedding economy and society in planetary boundaries.

Since English is not my native language I can not decide which one of the following two sentences is better.
- We help companies sell more and consumers pay less.
- Helping companies sell more and consumers paying less.
The first is a sentence and is fine.
The second is a phrase but would be better written as either of
depending on who you are helping.
There is no require for a corporate slogan to be a sentence.
At the least, sentence 2 should read Helping companies sell more and consumers pay less.
And it depends on how you are planning to use it. If this is a slogan for something I would use option 2. But then the logo/name of who is helping needs to be very visible for it to have an effect.
As an explanatory/informational sentence, you can use option 1.

Insights: An Ancient Window
The Newsletter of the Foundation for Ancient Research and Mormon Studies
The much-delayed and long-awaited examination of Wadi Sayq, a likely site for Old World Bountiful, became a reality recently. In April, a team of researchers examined the port area of Khor Kharfot ("Fort Inlet" in English) through which the Wadi Sayq enters the Indian Ocean on the southern coast of Oman, at the extreme western end near the border with Yemen. Their findings indicate that Khor Kharfot may be the site of Lehi's Bountiful.
Through almost one decade of preparatory research, Warren Aston of Australia, with the assistance of his wife Michaela, has identified this site as a possible location of ancient Bountiful where Lehi's party camped and built the ship by which they sailed to the promised land. F.A.R.M.S. support accelerated this work in the later stages.
In 1992 F.A.R.M.S. (with generous support from donors) and Brigham Young University funded an expedition to evaluate the site. The expedition was postponed when permission from the Omani government to conduct archaeological excavations on the site was held up, apparently due to sensitive negotiations between Yemen and Oman concerning their nearby border. Eventually the F.A.R.M.S. board of directors decided that a site survey without excavation could yield significant information and authorized the team to proceed.
Since excavation was not to be part of the expedition's work, the original team leader, David Johnson of BYU, whose major interest was excavation, was replaced by Noel Reynolds, the president of F.A.R.M.S., who was in Jerusalem at that time. Other members of the team included photographer Warren Aston; archaeologist Paolo Costa; and geologist William Christiansen.
The team assembled in Salalah, Oman, beginning April 10, 1993, and spent most of the following week on the site. The team's findings were reported in part by Costa at a meeting of the Seminar for Arabian Studies in London on July 24. We expect that further information about Khor Kharfot will be published soon in an article by Warren Aston in the Ensign.
1. Khor Kharfot used to be a small harbor formed by a seasonal river flowing out of Wadi Sayq into the Indian Ocean. Though it is now blocked year round by a beach thrown up by the ocean, it may have been open to the sea as recently as the present century.
2. Though the port is now uninhabited, there are surface ruins of dozens of structures. Minimally three different types which appear to correspond to ruins found elsewhere suggest at least occasional occupation of the general area over as much as a five-thousand-year period.
3. Even in the dry season, Khor Kharfot provides a sharp contrast to the arid land and sparse vegetation that characterize all areas a mile or further from the coastline. In the fall, after the summer monsoons, it is covered with a luxuriant green canopy. It features a variety of trees (including dates and figs), shrubs, flowers, and other plants. It is not yet known how the present ecosystem and plant species might differ from those of three thousand years ago. A Greek source describes a kind of tree growing in nearby Bahrain in 300 B.C. that when used to build boats would resist the water for 200 years or more.
4. Geological and archaeological evidence suggest that, as might be expected from the known gradual desiccation of the Arabian Peninsula over the last five thousand years, the present supply of fresh surface and spring water in Khor Kharfot is much less than in times past.
5. Wadi Sayq is unique among Omani wadis in that it runs due west and provides access to a Yemen plateau. This plateau leads directly west into the area long identified with the Nahum tribe. The center of this ancient tribal area is less than one-half degree off due west from Khor Kharfot. (After burying Ishmael at Nahom, Lehi's party traveled nearly due east until they hit the sea.)
6. While remote and protected by rugged terrain and the ocean, Khor Kharfot is accessible in several ways. Though the wadi is protected from the view of passing vessels, due to the oblique angle at which it reaches the sea, it is a simple matter to land a boat there. While the coastline is quite rugged, it is possible to move up and down it on foot. This does, however, entail endless climbing up and down the mountainside to avoid impassable ravines. There is also an improved trail (possibly of ancient construction) which rises directly up the mountain from the springs, working its way between cliffs and rock outcroppings to the plateau above. These are all difficult trails which would be relatively simple to defend. The wadi itself provides an easy trail into the deep interior of the country, but is only readily accessible from the plateau at some distance from the coastline.
7. No obvious source of ore has been identified at or near the site. However, ancient Oman was a principal source of metals for the Mesopotamian empires. Copper mines first developed five thousand years ago are now being worked with modern machinery and methods. The basic geological features of the entire country are similar. The wadi area abounds in chert (flint), providing stones that will start a fire.
8. Ancient Oman was an international center for trade by sea. Ships were built there to equip a commercial fleet that linked India, Persia, Mesopotamia, Africa, Egypt, and eventually China. Long before 600 B.C. the Omani seafarers were the Indian Ocean's equivalent of the Mediterranean's Phoenicians. In ancient times, it was the obvious place to build and launch a ship for a journey eastward into the Indian Ocean.
9. Khor Kharfot features a vast beach area, providing plenty of space to pitch tents. During the monsoon storms, the stone and thatch structures in the area may have been used as dwellings. It has been estimated that Lehi's party may have needed three years or more to build and adequately provision a ship for the Pacific crossing.
10. Khor Kharfot features several crop areas enclosed by stone fences and serviced by an irrigation system. While the present walls and canals probably date from the Islamic era, a similar farming system might well have preceded them.
11. Some apparently older ruins of probably less than a dozen small buildings, surrounded by a wall, lie above and beyond the rest. A trail (possibly constructed) leads down to the beach and main Wadi area. On the other sides this site is protected by high cliffs that drop straight into the sea and the mountain that rises directly behind it. Although the entire area is mountainous, this mountain would be the obvious one to call "the mountain." This site provides at ready hand a perfect place for throwing an undesirable person to his death in the sea (see 1 Nephi 17:48).
Khor Kharfot and its environs have all the features mentioned in the Book of Mormon in connection with Old World Bountiful. It has no features that would conflict with the Book of Mormon account. A survey of alternative sites in the Arabian Peninsula has turned up no others that come close to fitting the criteria for Bountiful so well. On this analysis, Khor Kharfot emerges as the most probable site for Lehi's Bountiful.
The F.A.R.M.S. banquet, an annual event that brings together F.A.R.M.S. subscribers, volunteers, researchers, members of the board of directors, and many other friends of the Foundation, will be held this year on Friday, October 29. The featured speaker will be Elder Dallin H. Oaks. In addition, F.A.R.M.S. board members will reflect on the nearly 15 years of F.A.R.M.S. projects and activities and report on the status of current projects.
The dinner will begin at 7:00 p.m. in room 375 of the Wilkinson Center at BYU. Reservations are required and may be made using the order form or by calling the F.A.R.M.S. office. Free parking is available in the parking lot next to the BYU Law school, directly east of the Wilkinson Center.
The Foundation looks forward to this opportunity to meet or become better acquainted with many of the people that support and carry out the work of F.A.R.M.S. and to share ideas and perspectives about the future of the Foundation.
The character and claims of Joseph Smith are fundamental to the claims of the Church he founded. Knowing this, critics of the Prophet have contended for more than a century and a half that he and his family were the kind of people from whom nobody would want to buy a used car, much less receive a plan of salvation.
The original anti-Mormon book, Eber D. Howe's 1834 Mormonism Unvailed (sic), featured affidavits gathered from former Smith neighbors by the excommunicated and bitter Phi-lastus Hurlbut describing the Prophet's family as, among many other derogatory things, "lazy" and "indolent." Joseph Capron, for example, declared that the Smiths' "great object appeared to be, to live without work." "It was a mystery to their neighbors," said David Stafford, "how theygot their living."1
Over the past several decades, Mormon scholars have subjected these affidavits and other such alleged "reminiscences" to sharp criticism.2 Nevertheless, these early documents have remained an anti-Mormon treasure trove to which generations

Cyclone Mocha: Cyclonic system is active in May and June every year and cyclones are likely to strike around June. In the past, storms like Vayu caused a lot of damage in Gujarat. This year, a storm system appears to form in the month of May and this storm has been named Cyclone Mocha 2023 Live Update Mocha. Let's know what the weather department has predicted?
The Indian Meteorological Department has predicted a new threat of cyclonic storm on Tuesday. , the IMD has said that a cyclonic system is likely to form over southeast Bay of Bengal around May 6, resulting in the formation of a low pressure area in the next 48 hours. Cyclone 'Mocha' the first cyclonic storm of the year 2023 has been predicted by the Meteorological Department in the month of May.
Hurricane Mocha 2023
According to IMD, a cyclone is likely to form over the Bay of Bengal on May 6. Regarding this, Director General of IMD Mritunjay Mohapatra said that some systems of Global Ensemble Forecast System (GEFS) have predicted it to be a cyclone. We are watching. Updates will be provided regularly. After the same prediction, Odisha Chief Minister Naveen Patnaik has ordered the officials to be prepared for any situation.
How did the name ' Mocha' come about?
The naming system for cyclones is adopted by the World Meteorological Organization (WMO) and the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP). If officially confirmed under the naming system, the name of the cyclone will be "Mocha". Cyclone 'Mocha' Yemen named this cyclone after the port city 'Mocha' on the coast of the Red Sea. Odisha Chief Minister Naveen Patnaik on Tuesday also convened a high-level meeting to review preparedness to deal with the cyclone and asked officials to be prepared following the IMD's forecast of the cyclone.
Cyclone 'Mocha' is named after which country?
Cyclone Mocha is named after Yemen.

Mar. 26, 2004 COLUMBUS, Ohio – Carbon dioxide, an environmentally friendly solvent for dyeing and dry cleaning, may become a valuable new tool for making medical implants, according to a study at Ohio State University.
Engineers here used compressed carbon dioxide (CO2) to push chemicals into a plastic that is often used as a bone replacement. With further development, the technology could be used in a wide range of plastics that release medicines -- from antibiotics to anti-tumor agents -– into the body.
The high-pressure, high-temperature CO2 is neither gas nor liquid, but is known as a "supercritical fluid," explained David Tomasko, associate professor of chemical engineering at Ohio State. Supercritical fluids are often used in industry because they penetrate materials like a gas but can dissolve some substances -- such as grease -- and other chemicals like a liquid.
"Though supercritical CO2 has long been developed as a means of extracting molecules, this work shows that it can be used in the opposite way," said David Tomasko, associate professor of chemical engineering at Ohio State.
The study also revealed that engineers can control the pressure of the CO2 to alter the internal structure of the plastic and create voids that may enable the material to hold larger quantities of medicine than might normally be possible.
Tomasko and John Lannutti, associate professor of materials science and engineering, their graduate students Taryn Sproule and Hongbo Li, and undergraduate student J. Alex Lee, published their results in a recent issue of the Journal of Supercritical Fluids.
Supercritical CO2 is gaining popularity as an environmentally friendly dry-cleaning agent and textile-dyeing solvent, but it is the fluid's ability to sterilize surfaces that could prove key for making medically active implants. Currently, implants are sterilized with heat, radiation, or chemicals that can make embedded medicines less effective, Tomasko explained.
The engineers' early tests with a protein solution suggest that supercritical CO2 may leave medicines intact.
They applied a coating of the protein solution onto dime-sized plastic disks with a cotton swab, and placed the disks in a glass tank, which they then filled with supercritical CO2. The proteins contained a fluorescent biomarker, so the researchers were able to track how well the proteins penetrated the plastic by examining cross-sections of the material under a microscope in ultraviolet light.
The microscope showed that the proteins survived the embedding process, and formed a layer 30 micrometers, or millionths of a meter, beneath the surface of the plastic.
Although the plastic -- polymethylmethacrylate, or PMMA -- was undamaged by the procedure, the interior of the disks foamed up into a Swiss cheese-like texture, with voids opening inside. The faster the engineers turned off the high-pressure CO2, the foamier the material became. Lowering the pressure slowly had the opposite effect.
Tomasko envisions that such voids within an implant could come in handy for holding extra quantities of a drug for long-term therapy.
Today, medical implants are used for mechanical support where tissue or bone has been removed. The researchers' vision is to "piggyback" drug delivery onto this mechanical function. The implant may be impregnated with drugs to prevent inflammation or infection following surgery. Or, in cases where a patient has had bone surgically removed as part of a treatment for cancer, doctors may also need to dispense anti-tumor agents from the implant for a longer period, Tomasko explained.
He's been working with David Powell, clinical assistant professor of otolaryngology, to investigate the potential use of such implants for patients who've had facial surgery.
Since completing their initial study, the engineers have begun using a porous glass disk to dispense protein solution onto the PMMA, instead of a cotton swab. Still, they found that the proteins don't penetrate the PMMA evenly, but form clumps instead -- an effect Tomasko suspects is due to the tightly packed polymer chains that make up the plastic.
"We think the CO2 lubricates the polymer chains so the protein molecules can slip in-between," he said.
For the next step in this research, the engineers will be working with biodegradable plastics and determine whether the medicine remains effective after being embedded with the supercritical fluid.
### Douglas Kniss, professor of obstetrics and gynecology at Ohio State, provided the protein solution, and Kathy Wolken, senior electron microscopist at the Campus Microscopy and Imaging Facility, assisted with the imaging of the PMMA samples.
This work was sponsored by the American Chemical Society's Petroleum Research Fund and the National Science Foundation, along with internal support from Ohio State. The Wright Laboratory's Materials Directorate at Wright-Patterson Air Force Base provided access to some of the equipment used in the study.

Regardless of whether you can appreciate the fact that wind turbines provide a valuable source of renewable resource electricity or you simply hate the look of them because they destroy your idea of what a landscape should look like, the fact is that wind power plants are popping up all over the country. Some people may have been wondering why there are red flashing lights mounted on top of the wind turbines that they see powering wind farms around the country.
The reason is because the Federal Aviation Administration (FAA) requirements state that all structures that are more than 200 feet tall must have aircraft warning lights. Due to the fact that a wind farm can comprise more than 200 wind turbines, lighting every single one of them is not only impractical it can also present a distinct annoyance to neighbours in the area. For this reason the FAA has considered an alternative to placing a light on every single wind turbine tower.
The compromise is to place lights on the perimeter wind turbines at a distance of no more than half a statute mile from the next. The flashing red lights are then synchronised so that they all flash on and off at the same time. These lights are only to be required at night and they are affixed to the nacelles of the wind turbines which is at the top of the tower, rather than at the highest point of the turbine.
Depending on whom you choose to listen to, red aviation lighting either does or does not attract migrating native birds. According to the FAA the flashing red lights that are used as aviation warnings do not have any noticeable effect on the birds in the area. However those who are in opposition to wind farms and the turbines that power them cite the possibility that birds will be more attracted to red flashing lights than they will to a white light.
No matter what the structure – radio tower, lighthouse or wind turbine – there will be the risk of bird strike. The question still to be answered is whether the number of bird and bat strikes is higher as a result of the presence of red flashing lights.
A constant concern that is voiced from local residents is the disruption the red blinking lights will cause to the surrounding area. It is not clear whether those who are opposed envisage that the lights are going to shine into the windows of their homes or simply disrupt their outlook at night.

IWU Flat Panel Request Form
IWU Flat Panel Policy
Flat Panel Procurement and Installation Procedures
Flat Panel Displays in Classrooms or Labs
List of current Flat Panel Displays in Conference Rooms
Consider the following before requesting a flat panel HDTV:
Please be aware that consumer electronics, like TV's and Apple TV's have a predictable lifespan, typically between 5-10 years, after which IWU requires the owner to fund the replacement of the equipment, due to the following concerns of aging equipment:
1.expiration of warranty (we purchase 4 or 5-year protection plans with all flat panel Tvs sized 42" and up);
2.perception of quality (unfortunately, the perception of the IWU brand can be negatively influenced by equipment which looks old, unkempt, or damaged);
3.security liability or vulnerability, especially of devices connected to the (wired or wireless) network;
4.availablity of support (labor and parts);
5.efficiency (newer electronics almost always consume less power than older electronics).
6.safety of people who may be in proximity of the electronic devices. Environments with high humidity, exposure to chemicals or excessive dust are more prone to ignite, or melt plastics, which can emit harmful odor.
Financial impact planning
Please be aware that there are financial implications attached to the purchase and installation of a flat panel HDTV.
There are electrical costs, both of installation, and ongoing power consumption.
There are HVAC costs, because electronic devices do emit heat, which can increase the cost of cooling, and can alter the effectiveness of thermostats located nearby,
There are bandwidth issues related to devices connecting to the wired and wireless network. Many new Smart TVs have wireless access points built-in, which can be confusing to mobile devices when not connected to an internet connection.
For these reasons, IWU's Information Technology has instituted a technical equipment refresh cycle, and will encourage you to budget for the replacement of this equipment, starting at about the 5th year after the original purchase. To discuss the predicted life span of equipment in your department or office space, please contact the office of Institutional Media Technologies.

Low carbon vehicle scheme receives Government boost
A £23m demonstration programme to encourage UK transport operators to buy and use low carbon commercial vehicles is set to receive over £11m in Government support.
The Government funding will help operators establish and run fleets of alternative and dual-fuel heavy-goods vehicles by meeting part of the difference in capital cost between traditional vehicles and their low carbon equivalents.
Thirteen major companies, including Tesco, the John Lewis partnership, Robert Wiseman Dairies and the BOC Group are leading trials in the programme, while more than 300 low-carbon commercial vehicles will be involved.
Iain Gray, Chief Executive of the Technology Strategy Board, who are managing the programme, said: "This trial will enable commercial vehicle operators to showcase alternative-fuel commercial vehicles. It will help to accelerate a wider understanding and acceptance of low carbon vehicle technologies, while enabling the development of alternative fuel infrastructures."
The funding will also help meet the cost of the refuelling points for use by the trial fleets, including the provision of eleven new public access refuelling stations around the country, which will be available for use by other operators.
Freight Minister Mike Penning said: "These trials will reduce CO2 emissions from freight and provide important information from a range of real-life situations that will increase industry confidence in low carbon trucks in the long term.
"For example, operators often cite lack of gas refuelling infrastructure as a barrier to the take up of alternatives to diesel. These trials include £2.4m funding for publicly accessible gas stations which will encourage investment in low carbon trucks, and other vehicles, delivering long term benefits for the environment and reduced costs for operators."

Is Shakeology safe while pregnant or nursing?
Is Shakeology safe while pregnant or nursing?A lot of people ask if it's safe to consume Shakeology while they are pregnant or nursing. While I appreciate when moms are careful about what they eat when they're eating for two. I can't help but wonder if they asked the same question about processed foods with preservatives and dyes. Or meat that includes the infamous "pink slime." Eeeeww! And although I'm not a nutritionist or medical professional, the short answer is: Yes! Shakeology is safe for pregnant and nursing moms and their babies–unless the mom has an allergy or sensitivity to an ingredient. So for those who just wanted the short answer, you don't have to read any further, but you should.
It's important to note that only 6% of all physicians in the US receive formal nutrition training (statistic quoted from the film "Food Matters") and many do not learn about breastfeeding, either. Women have told me that their doctor told them Shakeology is not safe for pregnancy due to the amount of vitamin A in it. This tells me that the doctor is only partially educated on the matter. It is true that high amounts of vitamin A in the form of retinol–which is preformed vitamin A from animal sources–have been correlated to birth defects. However, the vitamin A in Shakeology is in the form of plant-based beta carotene, which converts to vitamin A in the body. No studies at all have suggested that beta carotene has any correlation to birth defects. The rate of conversion of beta carotene to vitamin A is drastically reduced when higher amounts are ingested, preventing toxicity and teratogenicity. The Teratology Society concluded that beta carotene is not a teratogen (substance that causes birth defects) according to an excellent article by the Illinois Teratogen Information Service.
Shakeology is made from all natural ingredients, none of which are contraindicated for pregnancy or breastfeeding. Check out this video about where the ingredients come from.
You should always seek advice from a medical care provider, however–based on the fact that most have not had formal nutrition training, it is important to do your own research as well. Ask lots of questions and find out the reasons for any medical advice you receive. It is important to remember that doctors do not always agree on what's best, and they are advisors, not the ultimate decision maker. You are the only one in charge of your body, your baby and the health of both of you!

St Patrick's Trian
Kids love this place, which in three separate and highly interactive exhibitions tells the history of Armagh, the story of St Patrick and recounts the tale of Gulliver's Travels.
The name Trian [say: Tree-an] is taken from the three old divisions of Armagh – into Irish Town, English Town and Scots Town, but the stories it tells have much wider interest and they are very well told.
The Armagh Story
You will have driven through Armagh by the time you see this, and will see how the city grew, from it's earliest pre-Christian origins though the arrival of St Patrick, raids by the Vikings and the development of a fine Georgian city right to the modern day.
It is not a dull presentation – kids are engaged with drawings and via interactive screens and get to join in with activities along the way.
St Patrick's Story
Much of what was know about St Patrick is contained in The Book of Armagh, a treasure of early Christian Ireland which is on display here in facsimile (you can see the original in Trinity College, Dublin).
In this part of the Trian we learn not just about St Patrick, but about how these manuscripts were created. Visitors can trace some of the images from the book – after they have learned to make their own ink and quill pen! Interactive displays allow you to converse with and question some of those involved in creating the book.
Here the world expands and you become a tiny lilliputians, donning costumes and sitting in huge chairs, as you enter the home of the giant Gulliver to hear his amazing story.
It's really fun and you even get to tie up the giant!
Visiting St Patrick's Trian
The exhibitions are open year round, all day Monday-Saturday, afternoons only on Sunday. More detailed info at the website.
There is an auditorium at the site where events of various kinds, including musical events, are held. There is no information about these on the website, so you will need to contact them to find out if there is anything on when you are in the area.
The is a nice bright and airy cafe at the centre, serving good snacks and light meals, with a terrace to eat on if the weather allows.

Thermally conductive and electrically insulating alumina-coated graphite/phthalonitrile composites with thermal stabilities
Alumina-coated graphite (Al2O3@graphite) core-shell particles were firstly synthesized by a liquid-phase chemical precipitation with the aid of sodium dodecyl sulfonate (SDS) surfactant using an inorganic precursor, then to fabricate thermally conductive and electrically insulating phthalonitrile composites by a hot-compression method. The obtained composite with 40 wt% Al2O3@graphite exhibited a thermal conductivity of 1.409 W/mK, 6.6 times that of pristine phthalonitrile matrix (0.214 W/mK). And the composites still retained electrical insulation below 20 wt% Al2O3@graphite content. Moreover, excellent thermal stabilities had been observed, compared with the glass transition temperature of pristine phthalonitriles (460 °C), the glass transition temperature of the composites decreased slightly but still high. Additionally, at 20 wt% content, the weight loss temperature (T5 and T10) and the char yield at 1000 °C (Yc1000) were 525 °C, 589 °C and 74.9% which was 8 °C, 14 °C and 3.1% higher than that of pristine phthalonitriles, respectively, which holds potential for use in the high temperature thermal management.

different compilation units is not well defined. Order of destruction is the reverse of initialization order but initialization order itself is implementation defined. Bring order to this chaos.
 - The destructor of static objects are non-trivial and have important side-effects that have to happen
Solution and Sample Code
The following idioms are commonly used to control the order of initialization of static objects.
Safe Bool
Intent
To provide boolean tests for a class but restricting it from taking participation in unwanted expressions.
Also Known As
Motivation
User provided boolean conversion functions can cause more harm than benefit because it allows them to participate in expressions you would not ideally want them to. If a simple conversion operator is defined then two or more objects of unrelated classes can be compared. Type safety is compromised. For example,
struct Testable
{
 operator bool() const {
 return false;
 }
};
struct AnotherTestable
{
 operator bool() const {
 return true;
 }
};
int main (void)
{
 Testable a;
 AnotherTestable b;
 if (a == b) { /* blah blah blah*/ }
 if (a < 0) { /* blah blah blah*/ }
 // The above comparisons are accidental and are not intended but the compiler happily compiles them.
 return 0;
}
Solution and Sample Code
Safe bool idiom allows syntactical convenience of testing using an intuitive if statement but at the same time prevents unintended statements unknowingly getting compiled in. Here is the code for the safe bool idiom.
class Testable {
 bool ok_;
 typedef void (Testable::*bool_type)() const;
 void this_type_does_not_support_comparisons() const {}
 public:
 explicit Testable(bool b=true):ok_(b) {}
 operator bool_type() const {
 return ok_ ?
 &Testable::this_type_does_not_support_comparisons : 0;
 }
};
template <typename T>
bool operator!=(const Testable& lhs, const T&) {
 lhs.this_type_does_not_support_comparisons();
 return false;
}
template <typename T>
bool operator==(const Testable& lhs, const T&) {
 lhs.this_type_does_not_support_comparisons();
 return false;
}
class AnotherTestable ... // Identical to Testable.
{};
int main (void)
{
 Testable t1;
 AnotherTestable t2;
 if (t1) {} // Works as expected
 if (t2 == t1) {} // Fails to compile
 if (t1 < 0) {} // Fails to compile
 return 0;
}
Reusable Solution
There are two plausible solutions: Using a base class with a virtual function for the actual logic, or a base class that knows which function to call on the derived class. As virtual functions come at a cost (especially if the class you're augmenting with Boolean tests doesn't contain any other virtual functions). See both versions below:
class safe_bool_base {
 public:
 typedef void (safe_bool_base::*bool_type)() const;
 void this_type_does_not_support_comparisons() const {}
 protected:

 safe_bool_base() {}
 safe_bool_base(const safe_bool_base&) {}
 safe_bool_base& operator=(const safe_bool_base&) {return *this;}
 ~safe_bool_base() {}
};
// For testability without virtual function.
template <typename T=void>
class safe_bool : private safe_bool_base {
 // private or protected inheritance is very important here as it triggers the
 // access control violation in main.
 public:
 operator bool_type() const {
 return (static_cast<const T*>(this))->boolean_test()
 ? &safe_bool_base::this_type_does_not_support_comparisons : 0;
 }
 protected:
 ~safe_bool() {}
};

// For testability with a virtual function.
template<>
class safe_bool<void> : private safe_bool_base {
 // private or protected inheritance is very important here as it triggers the
 // access control violation in main.
 public:
 operator bool_type() const {
 return boolean_test()
 ? &safe_bool_base::this_type_does_not_support_comparisons : 0;
 }
 protected:
 virtual bool boolean_test() const=0;
 virtual ~safe_bool() {}
};

template <typename T>
 bool operator==(const safe_bool<T>& lhs, bool b) {
 return b == static_cast<bool>(lhs);
 }

template <typename T>
 bool operator==(bool b, const safe_bool<T>& rhs) {
 return b == static_cast<bool>(rhs);
 }

template <typename T, typename U>
 bool operator==(const safe_bool<T>& lhs,const safe_bool<U>& rhs) {
 lhs.this_type_does_not_support_comparisons();
 return false;
 }

template <typename T,typename U>
 bool operator!=(const safe_bool<T>& lhs,const safe_bool<U>& rhs) {
 lhs.this_type_does_not_support_comparisons();
 return false;
 }
Here's how to use safe_bool:
#include <iostream>
class Testable_with_virtual : public safe_bool<> {
 public:
 virtual ~Testable_with_virtual () {}
 protected:
 virtual bool boolean_test() const {
 // Perform Boolean logic here
 return true;
 }
 };

 class Testable_without_virtual :
 public safe_bool <Testable_without_virtual> // CRTP idiom
 {
 public:
 /* NOT virtual */ bool boolean_test() const {
 // Perform Boolean logic here
 return false;
 }
 };
int main (void)
{
 Testable_with_virtual t1, t2;
 Testable_without_virtual p1, p2;
 if (t1) {}
 if (p1 == false)
 {
 std::cout << "p1 == false\n";
 }
 if (p1 == p2) {} // Does not compile, as expected
 if (t1 != t2) {} // Does not compile, as expected
 return 0;
}
In C++, address of protected members functions can't be taken in a derived class. Derived class could be a standard class, a class template or a specialization of a class template. Some implementations of safe bool idiom declare safe_bool_base::this_type_does_not_support_comparisons as protected, address of which can't be taken in the derived class - a requirement in reusable safe bool idiom.
An insightful discussion on the boost mailing list initiated by Krzysztof Czainski resulted in an implementation of safe bool idiom using CRTP as well as another using macros.
C++11
The C++11 standard provides explicit conversion operators as a parallel to explicit constructors. This new feature solves the problem in a clean way.[1][2][3]
struct Testable
{
 explicit operator bool() const {
 return false;
 }
};
int main()
{
 Testable a, b;
 if (a) { /*do something*/ } // this is correct
 if (a == b) { /*do something*/ } // compiler error
}

Scope Guard
Intent
 - To ensure that resources are always released in face of an exception but not while returning normally
 - To provide basic exception safety guarantee
Also Known As
Motivation
Resource Acquisition is Initialization (RAII) idiom allows us to acquire resources in the constructor and release them in the destructor when scope ends successfully or due to an exception. It will always release resources. This is not very flexible. Sometime we don't want to release resources if no exception is thrown but we do want to release them if exception is thrown.
Solution and Sample Code
Enhance the typical implementation of Resource Acquisition is Initialization (RAII) idiom with a conditional check.
class ScopeGuard
{
public:
 ScopeGuard ()
 : engaged_ (true)
 { /* Acquire resources here. */ }

 ~ScopeGuard ()
 {
 if (engaged_)
 { /* Release resources here. */}
 }
 void release ()
 {
 engaged_ = false;
 /* Resources no longer be released */
 }
private

Prior information about the average dielectric properties of breast tissue can be implemented in microwave breast imaging techniques to improve the results. Rapidly providing this information relies on acquiring a limited number of measurements and processing these measurement with efficient algorithms. Previously, systems were developed to measure the transmission of microwave signals through breast tissue, and simplifications were applied to estimate the average properties. These methods provided reasonable estimates, but they were sensitive to multipath. In this paper, a new technique to analyze the average properties of breast tissues while addressing multipath is presented. Three steps are used to process transmission measurements. First, the effects of multipath were removed. In cases where multipath is present, multiple peaks were observed in the time domain. A Tukey window was used to time-gate a single peak and, therefore, select a single path through the breast. Second, the antenna response was deconvolved from the transmission coefficient to isolate the response from the tissue in the breast interior. The antenna response was determined through simulations. Finally, the complex permittivity was estimated using an iterative approach. This technique was validated using simulated and physical homogeneous breast models and tested with results taken from a recent patient study.

The Meridians are a humanoid species who were the descendants of an expedition that was stranded on the planet Meridian, located in the Gamma Quadrant, during the 14th century. They spend sixty years in a non-corporeal state as the planet shifts between dimensions. While in physical form the Meridians are humanoid in appearance, with distinguishing markings near their eyes.
The passage between dimensions is a celebrated event on Meridian and is marked with first meal and last meal. The time spent in the physical universe is used to experience physical sensation, get to know each other, and raise families. (DS9: "Meridian")

A project team from Japan is working on a device that will create artificial meteor showers. Combining space technology with entertainment, Star ALE has in plan to offer a unique moment for the upcoming Tokyo 2020 Olympics.
The project will be an innovation to pyrotechnics and rocketry, and it will be able to display an artificial meteor shower by demand. The company has named it "Sky Canvas" and hopes that it will become a pioneer for an entirely new type of entertainment, space shows.
Sky Canvas wants to recreate the process of space particles creating plasma emissions while entering the Earth atmosphere. The sky will become an immense canvas for the members of this project, and they will try to display a fascinating patterns above the city.
Tests have shown that the particles launched into the Earth's atmosphere are perfectly visible from Tokyo, a city that has significant light pollution. While traversing the atmosphere, the particles will become shooting stars for those watching from the ground.
To create the meteor shower, hundreds of so-called particles will be loaded into a microsatellite. Then, a commercial launch vehicle will transport the microsatellites up to the lower surfaces of Earth's orbit. After that, the vehicle will stabilize in orbit and launch the particles.
This is not just a drop. The particles will travel one-third on the orbit of the Earth before entering the atmosphere and become a falling star. Falling through the air will cause a plasma emission that will appear bright in the sky.
The particles will burn in different colors, depending on which chemical element the company will use – lithium for pink, cesium for blue, strontium for red or copper for green. Also, the components are thus designed so that the trip on the sky will be slower so that everyone could enjoy it.
Measures of safety will be taken in order to avoid any collisions with other objects from space. Moreover, the company reassures the public that they will respect the international regulations and leave no debris in space. The microsatellites are designed to automatically burn-up after the show.
The production of such an artificial meteor shower will cost around $8,100, without taking into consideration the costs of the actual launch in space.
The first time an artificial meteor shower will be displayed on the sky will be during the upcoming 2020 Olympics in Tokyo.

Overview
This article explains how to retrieve the content of RichTextEditor at the tapped position.
Description
As S60 5th Edition devices are touch sensitive, the pointer events can be captured using HandlePointerEventL(). This is also used to handle such events as pointer down/up and dragging. Thus a class derived from CCoeControl can implement the HandlePointerEventL() function for customising the handling of pointer events.
In order to get the contents of the Editor, first we need to get the co-ordinates of the tapped event and then identify the document position of the nearest character edge to the window coordinates specified. This helps in retrieving the content (entire word) nearest to the tapped position.
Solution
Headers Required
#include <FRMTVIEW.H>
#include <TXTRICH.H>
Libraries
LIBRARY etext.lib
LIBRARY form.lib
The following code snippet enables the retrieving of the contents of the editor at the tapped position. This has to be used in HandlePointerEentL().
 TPoint tapPoint( aPointerEvent.iPosition );
//iEditor is a CEikRichTextEditor object
CTextView* iTextView = iEditor->TextView();
//Get the current document position based on the point where the stylus is tapped.
TInt docPos(iTextView->XyPosToDocPosL( tapPoint ) );
TInt start( 0 );
TInt length( 0 );
//By passing the current position of the document you can get the word information
//(the start position and the length)
iEditor->RichText()->GetWordInfo(docPos,start,length, EFalse, EFalse);
if ( aPointerEvent.iType == TPointerEvent::EButton1Down )
{
// Based on the start position and the length get the word information.
// using the method Mid(TInt aPos, TInt aLength) const;
// the word at the tapped position can also be modifed
}
The above code snippet can also be used for highlighted items like URLs, phone numbers, and HTTP addresses. The Item Finder API can be used for highlighting URLs, phone numbers, and HTTP addresses.
In order to identify whether the stylus is tapped on the tag or not, the method CursorOverTag() can be used. The method returns a boolean value besides giving the start position and the length of the tag.
TBool iFlag = iEditor->RichText()->CursorOverTag( docPos, parser, start, length );

Encyclopedia > Lockpicking
Lock picking is the art of unlocking a lock without its intended key. Locksmiths are trained in lock picking. The tools for lock picking are usually different for each type of lock and can sometimes be improvised from common items, such as hair pins or safety pins. Some people enjoy picking locks because it has hack value and doing so is fun to them.
Usually it is possible to bypass a lock without picking it. Most common locks can be quickly and easily opened using a drill, bolt cutters, or a hydraulic jack, or the hasp, door, or fixture they are attached to can be cut or broken. A lock that offers high resistance to picking does not necessarily make unauthorized access more difficult, but it will make surreptitious unauthorized access more difficult. Locks are often used in combination with alarms to provide layered security.

A tension wrench (or torque wrench) is used to apply a torque to the cylinder, while a lock pick (or picklock) is used to push individual pins up until they are flush with the shear line. As each pin is manipulated to its correct height, the cylinder will turn fractionally causing another pin to bind. The pins will not bind simultaneously because they will not be aligned perfectly with the axis of the cylinder. Once all of the pins are flush with the shear line, the tension wrench can be turned fully to open the lock.
Raking or scrubbing a pin tumbler lock is usually done before individual pins are pushed up. While applying torque with the tension wrench, a lock pick with a wide tip is placed at the back of the lock and quickly slid outwards with upward pressure so all the pins are pushed up. Raking may allow some of the pins to be flush with the shear line and can make the job easier.
Some pin tumbler locks have special pins, with serrations, mushroom heads, or spool shapes, that make lock picking more difficult by causing the pins to bind in locations other than their correct ones.
Another technique, often the fastest, uses a vibration pick or gun, which sharply strikes all the bottom pins simultaneously while light torque is applied; like a cue ball, the energy is transmitted through to the top pins, which fly to the top of their well. This momentarily creates a large space between the two pins.
To defend against these attacks, high-security locks use a sidebar, which engages from another axis and also prevents the lock from turning. Medeco does this by requiring the pins to be rotated to a correct position, as well as moved to their correct height. Other brands put the sidebar cuts in the side of the key.
Pin tumbler locks are sometimes arranged in groups, where each lock in the group can be opened by either a master key, which will open any lock in the group, or a specific change key, which will open only that one lock. This is done by using pins with more than two parts, so that it will shear at more than one position. In poorly supervised areas, those who have access to a door which is unlocked or for which they have a legitimate key can remove the lock from the door and disassemble it to determine the master keying pattern.
Tubular locks
A tubular lock pick is used to keep the pins from moving once they have been picked until all have been picked. These locks can be picked using a pin and a torsion tool, but using this method is very much slower than using a tubular lock pick, and for many locks the process has to be repeated up to four times to open the lock.
Disc tumbler lock
A double-sided pick can be used to keep the discs from moving once they have been picked until all have been picked.
Combination locks
Cheap combination padlocks can be opened using a thin metal piece slid between the body and shackle. More expensive ones require the lock-picker to find the combination to the lock. The exact technique to do can differ and some manufacturers, such as Master Lock, make this process very time-consuming on their latest models.
Warded locks
With a warded pick, warded locks are probably one of the locks easiest to pick. Warded picks have basic shapes that fit many types of warded locks. They are inserted into the key hole and slowly turned until the lock opens.
Car locks
Car locks can sometimes be opened by slipping a metal ruler that has had its end cut into a hook shape (a slim Jim), down the front of a car window (in between the rubber). The ruler is manipulated until the lock cable is caught on the hook. Pulling the cable up will open the door.

Lock picking - Wikipedia, the free encyclopedia (1660 words)
However, many lockpickers state that for most locking devices, a basic set of 5 picks should be enough, therefore it is unnecessary even to carry around a wide variety of professional lockpicks.
All responsibility concerning criminal or legal acts using the picks is taken by the owner of the lockpicks.
With criminal actions put aside, lockpicking is the ideal way of opening a lock without a key.
Lockpicking Equipment Primer (1151 words)
There are two versions of the lockpick gun, the standard mechanical version which has a trigger that has to be pulled in order to actuate the needle that will strike the pins.
Opinions vary widely on the benefit of the electric lockpick gun, one opinion is that the electric version is more comfortable to use as it doesn't require the repeated pulling of a mechanical trigger.
A drill is the all over best lockpicking tool there is. One drilling technique involves drilling over the shoulder of the keyway so as to drill through the pins and render them useless giving very quick access to the lock.

What will we do
Promote WBL will not only identify and share methods which help make work-based learning more effective, but it will also provide VET professionals with the knowledge and tools to make it happen through a dedicated online course. Our partnership aims to demonstrate that work-based learning in VET can be a win-win situation for both learners and the host employer.
Barriers to making this happen can be challenging to overcome. Issues we have identified include poor relationships and collaboration between VET providers and employers, and a significant skills gap among learners of transferable skills; especially their entrepreneurship capabilities. VET professionals play a key role in developing this agenda, as both relationship-builder with industry and as the deliverer of skills improvement in young people. Promote WBL will support the training of VET teachers to help their students to make the most of their work-based learning.
Through this we will support VET institutions to create a number of long-term collaborations between themselves and businesses of all sizes to create high quality work-based learning opportunities for their learners. It is also expected that, through Promote WBL's contribution to a more effective learning experience for students, we can help to influence an increase of early employment outcomes.

Co-authored documents are becoming increasingly important for knowledge representation and sharing. Tools for supporting document co-authoring are expected to satisfy two requirements: 1) querying changes over editing histories; 2) maintaining data consistency among users. Current tools support either limited queries or are not suitable for loosely controlled collaborative editing scenarios. We address both problems by proposing a new persistent data structure-partial persistent sequence. The new data structure enables us to create unique character identifiers that can be used for associating meta-information and tracking their changes, and also design simple view synchronization algorithms to guarantee data consistency under the presence of concurrent updates. Experiments based on real-world collaborative editing traces show that our data structure uses disk space economically and provides efficient performance for document update and retrieval.

Docker : Oracle Database on Docker
This article describes a simple build for running an Oracle database on Docker.
Related articles.
Assumptions
This article assumes the following.
Build the Image
The Dockerfile and scripts this article is based upon can be found here. The build expects the following file system. You will have to download the Oracle 19c database and APEX software yourself and place it in the "software" directory.
$ tree
.
├── Dockerfile
├── README.md
├── scripts
│ ├── healthcheck.sh
│ └── start.sh
└── software
 ├── apex_20.2_en.zip
 ├── LINUX.X64_193000_db_home.zip
 └── put_software_here.txt
$
The Dockerfile contains some basic instructions, which will be described further here.
With all the files in place you can build the image using the following command.
$ #Docker
$ docker build -t ol7_19:latest .
$ #Podman
$ docker build --format docker -t ol7_19:latest .
The build performs the following actions.
You will notice the build phase doesn't create a database. That is done on the first run of a container.
Run a Container
The database is created the first time the container is started, which means it can take some time for the container to be fully operational, especially because we are also doing an APEX installation into the database.
The simplest way to run a container based on this image is to accept all the defaults and run the following command. It gives the container a name (ol7_19_con), binds a host port to the exposed container port.
$ docker run -dit --name ol7_19_con \
 -p 1521:1521 \
 --shm-size="1G" \
 ol7_19:latest
In the previous example the storage is not persistent, so if the container were removed the database files would be lost. We can solve this problem by creating a directory on the host file system and mounting it to "/u02" in the container. Now the data files reside outside the container. See the Persistent Storage section about the setup of the host volume.
$ mkdir -p ~/volumes/ol7_19_con_u02/
$ docker run -dit --name ol7_19_con \
 -p 1521:1521 \
 --shm-size="1G" \
 -v /u01/volumes/ol7_19_con_u02/:/u02 \
 ol7_19:latest
We could have used a managed volume or a data volume container instead. These approaches are described here.
In the previous examples we've exposed the database to the outside world, but if we want other containers to speak directly to it, we must create a Docker network and associate the container with that network.
$ docker network create my_network
$ docker run -dit --name ol7_19_con \
 -p 1521:1521 -p 5500:5500 \
 --shm-size="1G" \
 --network=my_network \
 -v /u01/volumes/ol7_19_con_u02/:/u02 \
 ol7_19:latest
So far we have relied on the default settings for the database creation, but we can influence this by setting the appropriate environment variables in the run command.
$ docker run -dit --name ol7_19_con \
 -p 1521:1521 -p 5500:5500 \
 --shm-size="1G" \
 -v /u01/volumes/ol7_19_con_u02/:/u02 \
 -e "ORACLE_SID=cdb2" \
 -e "SYS_PASSWORD=SysPassword2" \
 -e "PDB_NAME=pdb2" \
 -e "PDB_PASSWORD=PdbPassword2" \
 -e "APEX_EMAIL=_EMAIL_" \
 -e "APEX_PASSWORD=ApexPassword2" \
 ol7_19:latest
Persistent Storage
If you are using an external host volume for persistent storage, the build expects it to owned by a group with the group ID of 1042. This is described here.
start.sh Script
The start.sh script is responsible for creating the database on the first run of the container. It performs the following actions.
healthcheck.sh Script
The healthcheck.sh script is really simple. It connects to the database and runs a query. If the query is successful it returns "0", otherwise it returns "1".
Managing the Container
Once the container is running you can connect to a bash shell using the following command.
$ docker exec -it ol7_19_con bash
The container can be stopped and started using the following commands. The "--time" parameter give the database a chance to shutdown gracefully. Restarting the container has no impact on ephemeral storage, so no data will be lost, even if you are not using persistent storage.
$ docker stop --time=30 ol7_19_con
$ docker start ol7_19_con
The following command removes the container and the associated volumes. If you are not using persistent storage this will result in the loss of the database files.
$ docker rm -vf ol7_19_con

Hope this helps. Regards Tim...

Mississippi elementary and middle school teachers have a new tool to improve academic performance in the classroom.
The Mississippi Department of Education has launched a new campaign to help teachers incorporate physical activity into lesson plans. The "Move to Learn" campaign is based on two academic studies that show a correlation between increased fitness and improved test scores, as well as fewer absences and fewer disciplinary incidents at school.
"The two studies, 'Fitness Among Mississippi Students,' and 'Increasing Fitness to Improve Academic Performance,' also showed this correlation applies across all socio-economic and demographic categories," said Anne Travis, chief executive officer of the Bower Foundation, in an email.
The Bower Foundation provided the funding to the Education Department for the "Move to Learn" campaign.
The campaign provides teachers with videos and lesson plans they can access online that incorporate physical fitness into the classroom. The "Move to Learn" website also includes examples of schools that are already using physical activity to improve academic performance.
"We started with a 13-minute video that highlights success stories in Mississippi schools that have incorporated physical activity into the day beyond physical education requirements," said Scott Clements, director of the Mississippi Office of Healthy Schools.
Clinton said MDE officials traveled the state looking for schools that were using physical activity in the classroom. In Clinton, they found a school where the children were dancing in the hallways. Tardiness went down at that school, Clements said.
The website includes 10 five-minute video segments — five for K-3 students and five for elementary and middle school students.
"The teacher can stream or download (these video segments) and do a video break," Clements said. "(The teacher) gets the kids moving and then they're better ready to learn."
He said the campaign, with its emphasis on physical activity, addresses his concern about obesity in Mississippi students. Studies have shown that Mississippi has the most obese children of any state in the nation.
"That's the win-win piece of it," he said. "We feel like we're winning every way around on this thing. We're in the bottom in health and education. With this one project, we can address both at one time."
Clements said MDE is getting the word out any way it can.
Officials are talking about the website at conferences, publicizing it when they go to school districts and sending out messages to teachers over the Internet.

Town Analyses > Jericho > Physical Landscape
There are 78 different types of soil identified within the Jericho borders, a product of the area's dynamic glacial past. Distinguishing one soil from another is the product of several factors, including the type of bedrock underlying all other deposits, the surficial material coating the bedrock, the steepness of slope on which the soil lies, the climate or microclimate that determines the rate of decomposition, the size of soil particles, and the mineral composition of the soil itself.
Why do we bother dividing soils into different types? Soil structure often dictates what types of vegetation will grow naturally on a landscape, and human activities and land use practices are often more suitable on one type of soil over another. Farming, for example, is most productive on soils with relatively high clay content that has mixed with sand for better drainage. Also, it tends to be level and free of many rocks. Although most of Vermont was cleared for farming at some point in the state's history, we can actually see a relationship between soil type and date of farm abandonment, where the prime soils are most likely to remain farms even today. Most of the prime soils are located along river floodplains, where clay was once deposited when the land was covered by a lake, but where sand has more recently been mixed with the clays. Upland farms, with soils derived from rocky glacial till, were often the first to be abandoned.
Certain trees and vegetation may also grow better in one soil than another, which eventually leads to animal habitat also partially corresponding to soil type.

Gmail Child Account
I was visiting a friend the other day and his young child was complaining that she wanted an e-mail address. She wanted one to keep in touch with her aunt and uncle, who had told her to e-mail them. My friend explained to her that she could use his, but she wanted one with her name in it. My friend was wary of creating one for her, because of all the bad spam she'd get and he also wondered how he would be able to monitor her account.
Well, when I went home, I did some research and found out that users of the Gmail e-mail program can create a parent and child account. Cool, huh?! Read on for some more details.
If you want to create a sub-account (child account), just follow these directions:
1.) Log in to your Gmail account.
2.) In the upper right hand corner, click Settings.
3.) Select the link that says Accounts. Below that, select the link that says "Add another e-mail address."
4.) When asked what e-mail address you'd like, type your Gmail user name, followed by a plus sign and the name of the child's account, with no spaces. For example, if your Gmail address was _EMAIL_ and the child's name was Jenna, you'd type in _EMAIL_. When you have finished, click the Next Step button.
5.) Now, when your child goes to compose an e-mail, in the From: drop down menu, they can select their account instead of yours.
Any messages or replies sent to that account will appear in your Inbox and you can tell your child when they have a new message. It's the perfect way to give your child what they want, but still keep a close eye on what they do while on the Internet.
You can even create multiple child accounts. Heck, they don't even necessarily have to be for a child. They can be for whatever you like!
Not a shabby deal, huh?!

Few things spark up a dull winter landscape like the glowing red-orange stems of coral bark willow. This hardy, fast-growing plant grows naturally as a large tree, but it can easily be turned into a multi-stemmed shrub by annual coppicing (cutting stems back nearly to the ground). The brightest stem color occurs only on young stems, so coppicing keeps the plant small and leads to the best bark display. Coral bark willow has narrow, medium green leaves that turn yellow in the fall. It can be grown singly or, for real punch, in groups or as hedges.
Common name: Coral bark willow
Botanical name: Salix alba subsp. vitellina 'Britzensis' (syn. S. alba 'Britzensis')
Plant type: Deciduous tree
Zones: 3 to 8
Height: 40 to 60 feet (6 to 10 feet if grown as a coppiced shrub)
- Sun: Full sun
- Soil: Adaptable to most soil types
- Moisture: Average to moist
- Mulch: 2 to 3 inches of wood chips or other organic mulch
- Pruning: To grow as a shrub, cut all stems back to within a few inches from the ground in early spring each year. For tree form, just prune lightly to improve form and remove any damaged branches.
- Fertilizer: None, or apply compost or balanced fertilizer as needed
Pests and diseases
- Susceptible to some insects (willow leaf beetle, stem borer, aphids) and diseases (cankers, leaf blights)
- As with most willows, coral bark willow prefers moist soil and does especially well near ponds or streams.
- The colorful stems look great in winter arrangements outdoors or indoors.
All in the family
- Coral bark willow is a member of the willow family (Salicaceae), which also includes poplars and aspens (Populus spp.).
- There are about 400 species of willow (Salix) ranging from trees 80+ feet tall to creeping alpine plants less than 6 inches tall.
- Willow bark extract has been used as an anti-inflammatory for centuries; it contains salicylic acid, which was a key ingredient in the first forms of modern aspirin.

Peirescius is a lunar impact crater that is located in the southeastern part of the Moon. It is close enough to the limb that it appears significantly foreshortened when viewed from the Earth, even though it is nearly circular in shape. To the west-northwest of Peirescius is the crater Vega, and less than one crater diameter to the south is Brisbane. Farther to the east is the Mare Australe.
The outer parts of this crater has become eroded by smaller impacts, and several small craterlets lie along the rim or the inner wall. These have taken their toll upon the original crater shape, although it is nowhere near as badly eroded as the nearby Vega. The interior floor is a relatively featureless expanse, with only a low rise in the center and a small craterlet toward the northern rim.
The crater was named in 1935 after Nicolas-Claude Fabri de Peiresc (1580–1637), the French astronomer, antiquary and savant.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Peirescius.

Counterfactual Fairness in Java
Here we will look at how to build a counterfactually fair model, as detailed in Counterfactual Fairness, specifically the "Fair Add" model.
This implementation will rely mostly on Apache Commons Math1 linear regression implementations, namely the Ordinary Least Squares (OLS) regression2. We start then by adding the relevant Maven dependencies:
Data will be passed as a RealMatrix3. This matrix will have dimensions \(N\times f\), where \(N\) is the number of observations and \(f\) is the number of features.
We can instatiate the model using
// RealMatrix data =...
final CounterfactuallyFairModel model = new CounterfactuallyFairModel(data);
We will then need the following information:
Assuming that we have the same variables as in the counterfactual fairness example, let's say that the protected attributes have in the data matrix, column numbers 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and the model variables (LSAT and UGPA) have indices 1, 0 and the target (ZFYA) has index 2. We then calculate the counterfactually fair model using:
 new int[]{1, 0}, 2);
The calculate method performs the following:
public void calculate(int[] protectedIndices, int[] variableIndices, int targetIndex) {
 final RealMatrix residuals = new
 for (int i = 0; i < variableIndices.length; i++) {
 final int index = variableIndices[i];
 final RealVector varResidual =
 this.calculateEpsilon(protectedIndices, index);
 residuals.setColumn(i, varResidual.toArray());
 // predict target from residuals
 final OLSMultipleLinearRegression regression = new
As in Counterfactual Fairness, we calculate a regression model to predict each of the variable (LSAT and UGPA) using the protected variables. The resulting residuals, \(\epsilon_{LSAT}\) and \(\epsilon_{UGPA}\) will in turn be used to calculate another regression model in order to predict the target variable ZFYA.
The residuals are calculated using the calculateEpsilon method, which consists of:
public RealVector calculateEpsilon(int[] protectedIndices, int targetIndex) {
 int[] protectedRows = new int[];
 Arrays.setAll(protectedRows, i -> i);
 final RealMatrix _x =,
 final RealVector _y =,
 new int[]{targetIndex}).getColumnVector(0);
 final OLSMultipleLinearRegression regression = new
 regression.newSampleData(_y.toArray(), _x.getData());
 return new ArrayRealVector(regression.estimateResiduals());
Which simply calculates a regression model for the variables using the protected attributes and returning a RealVector with the residual \(\epsilon\).
