Retrieving Metadata from an Analytical Data Source
Metadata is important to applications that retrieve and work with analytical data. When retrieving data from a relational data source, the dimensionality of such data is predictable, even with nested datasets. Result sets from a relational database are typically two-dimensional or scalar in structure. However, data retrieved from analytical data sources can be of variable dimensionality, organized along potentially deep hierarchies.
To handle the complexity of metadata retrieval from analytical data sources, ADOMD.NET provides two forms of metadata retrieval:
 - The Object Model
 The ADOMD.NET object model is generally easier to use than schema rowsets. For most scenarios, you can access the metadata of various database objects just by using the object model. ADOMD.NET exposes the object model through the AdomdConnection.
 For more information: Working with the ADOMD.NET Object Model
 - Schema Rowsets
 A complete, but more difficult approach to retrieving metadata is through using schema rowsets. A schema rowset is an OLE DB rowset that encapsulates the description for all objects of a particular type in the database. Schema information in an analytical data source includes databases or catalogs available from the data source, cubes and mining models in a database, roles that exist for cubes at the data source, and so on. This metadata can be retrieved by using the GetSchemaDataSet method, passing in either a GUID or an XML for Analysis (XMLA) name.
 For more information: Working with Schema Rowsets in ADOMD.NET
Each of these metadata retrieval methods access different types of metadata. The following table describes the different metadata available for each method, and the methods used to access it.

Damages in Comparable Coaches' Contracts to Assess a School's Economic Damage from the Loss of a Successful Coach
Richard T. Karcher
Professor of Law
Florida Coastal School of Law
This Essay addresses the difficulty of proving financial harm that results when a head coach departs during the contract term and the school thereby abruptly loses a valuable asset, that being a successful and stabile athletic program. Due to the unique and specialized nature of head coaches' services and the industry they work in, ordinary measures for assessing damage based on substitute performance and transaction costs are insufficient. The author offers a theory of measuring a school's damages within the construct of a lost income-producing asset valuation, using a methodology based on liquidated damage amounts in comparable coaches' contracts.

Ukrainian-American company EOS Data Analytics proposes to Ukrainian farmers to overcome the negative effects of the COVID-19 pandemic. Free access to the EOS Satellite Monitoring Platform for Crops gives farmers an opportunity to spend more time at home.
Satellite Field Monitoring Platform is a cloud service that uses satellite imagery to monitor crops and provide farmers with important, up-to-date information on their condition.
According to information provided on the company's website, farmers are offered commercial images with a resolution of ~ 0,5–1,5 megapixels as an autonomous data source for analytics. A high level of detail allows farmers to receive accurate and authentic information.
EOS Crop Monitoring enables farmers to make rational decisions based on the data they receive. The technological platform informs users about the features of vegetation, warns about sudden changes of weather, and automatically determines priority tasks. Thanks to satellite data, the condition of the fields may be monitored without leaving the home. Minimizing people's contacts is very important during the quarantine.
The company representatives said they made free access to the platform to support farmers during a pandemic. The offer is valid until April 30, 2020. To start using, you need to register on the platform site and receive a letter with instructions for access.
"Doctors are fighting for our today, while farmers are working for our tomorrow. We cannot imagine a world where agriculture has simply stopped working. So we want to help those who work even in the current situation," said Alexander Sakal, a business Development Director, EOS Crop Monitoring.
He added that many farmers from different countries were interested in this proposal after the launch.
EOS Data Analytics is an international company that provides analytics cloud solutions and services based on satellite and geospatial data. The company's partners include leading satellite data providers who receive information from the Landsat, MODIS and Sentinel projects.
EOS Crop Monitoring uses machine algorithms and satellite image processing to offer online agricultural monitoring, and analytics solution. In Ukraine, the company also became a participant of the project "Supporting transparent land governance in Ukraine" supported by the World Bank and the EU. Under this project, Ukraine Crop Map was created. A lot of unregistered but cultivated plots were uncovered.

Store Table (ST)
Command title
Store Table
Description
The ST command stores the table — table data and table definition — to a tableBASE library.
COBOL syntax
MOVE 'ST' TO xxxx-COMMAND.
CALL 'TBLBASE' USING TB-PARM
 xxxx-COMMAND-AREA.
C syntax
memcpy( tbCommArea.tbCommand, "ST", 2 );
TBLBASE( &tbParm, &tbCommArea );
Parameters
None
Explanation
The ST command does not close the table. If an ST command addresses an Alternate Index, a new generation of the Data Table is actually stored instead; there is no effect on the Alternate Index itself.
Return value
ERROR 0018 occurs if there is insufficient space in the library.
ERROR 0019 occurs if the table is newly defined using DT or CN and a table with the same name is found in the library during the store.
Notes
tableBASE stores a new generation of a table before it deletes the oldest generation, if appropriate. Even if only one generation is to be kept, the new version of the table will be stored before the old space is released.
When stored, newly defined tables are automatically stored on the first library in the LIB-LIST (as set by the ML command) at the time of definition.
tableBASE does not permit a store of a newly defined table if the library contains a table with the same name. This prevents the inadvertent replacement of a previously defined table.
A table that has been read from a library will be stored into the library from which it was obtained, unless intentionally diverted by a DV or DW command.
Exceptions
None

The cycle double covering conjecture states that every bridgeless graph admits a collection of cycles such that every edge in the graph is contained in exactly two cycles from the collection (allowing repetitions). The counterexample with the smallest number of edges is proved to be cubic. My first question is that whether it is true that such a minimal counterexample has the property that removing every edge yields a bridge. In other words, is it true that if $G$ is a graph with a cycle double covering, then $G\cup e$ also has a cycle double covering, where $e$ is an added edge between two vertices of $G$?
My second question is whether anything is known regarding cycle coverings that cover every edge the same number of times.

No. In a minimal counterexample of the cycle double cover conjecture, removing an edge creates no bridges. The reason is simple. If such an edge existed, then contracting it would yield a smaller counterexample. In fact it is known that a counterexample to the cycle double cover conjecture with the smallest number of edges is a Snark. For more information I suggest looking at M. Chan's survey on the cycle double cover conjecture.
As for your second question, it is known that every bridgeless graph has a cycle cover which covers every edge precisely $2k$ times for every $k\geq 2$. So in particular there is always a cycle 4-cover. This is all stated with references in the survey I mentioned above.
share|improve this answer
Thanks Gjergji. So it follows that such a minimal graph $G$ admits a cycle covering so that every edge is covered exactly $2E-2$ times, where $E$ is the number of edges of $G$. Maybe there is a more trivial way of covering a graph with cycles that cover all edges the same number of times? Also do we know for example if there is a quadruple covering (or a number smaller than $2E-2$)? – Hej Jun 4 '12 at 2:03

I have a question about glare analysis using Grasshopper and Honeybee.
I would like to use a fish-eye camera to take a luminance image, convert it to HDR format and measure DGP using honeybees.
There are equiangular projection, hemispherical prejection and stereographic projection for the projection method of the fisheye lens in Radiance.
Fisheye can be selected by "image based simulation" of Honeybee component, but the projection method of the fisheye lens cannot be set, and it is unknown.
Does anyone know which projection type of the fish-eye lens is used in the component of Honeybee "image based simulation"?
Any suggestions or expanation would be appriciated.

Colonial Williamsburg Teacher Institution Programs
It' s hard to believe, but many organizations are already accepting applications for teacher institutes occurring this coming summer. If you have never attended an institute at an historic site, you will walk away with a tremendous amount of new knowledge! Click on the links below for more information. Some topics include:
- Becoming Americans (1606–1781) (for educators in grades 3–6)
- African Americans in Eigteenth-Century Virginia (for educators in grades 3–8)
- Straight from the Sources: Women in Eighteenth-Century Virginia (for educators in grades 3–8)
- Apprenticeships, STEM, and Colonial Daily Life (for educators in grades 3–8)
Tennessee State MuseumDigital Learning Opportunities
Interview with a Historic Figure: In this program, a well-known Tennessean will be chosen by the teacher from the list below. When you connect with us, one of our educators will dress in period garb and take on the persona of the chosen figure. Your students will then act as reporters and interview this figure about their life and times. After the program, they will take what they have learned and write an article for their local newspaper. Students will be responsible for asking detailed questions of their subject in order to create an accurate narrative of their life and their impact on Tennessee history.
Mystery Artifacts: (Grades 3-8) When signing up for this program, teachers will be able to choose a subject and subsequent list of artifacts, all of which represent each exhibit in our museum. The teacher will be given background information on the objects ahead of our program date, but they will remain a complete mystery to the students. Once we are connected on screen, one of our educators will provide a quick introduction of why we are meeting and what the rules are of the "game." They will then have a limit of twenty questions to ask our educator, and about 30 minutes, to figure out what the artifacts are and what they were used for during that particular time period. Once the students have made their final guesses, an educator will finish the session by revealing the correct answers, and then go on to detail the history of each object, explain how it was used and describe why it is important.
Mystery Skype: This program explores the subject of United States geography and history! Once connected with one of our museum educators, the goal of this session is to let the students ask us geography based questions in order to correctly guess our location within the United States. Your students will need to prepare a list of spatial and directional questions before we connect, and it is vital that you do not give your kids any hints to our location before our session. Once they have correctly guessed where we are, your students will be given a brief history of Tennessee and, if time allows, we will open the floor for any other questions they might have!
Women's Suffrage CentennialTDOE Featured Content
This month the Tennessee Department of Education is highlighting the formation of women's associations and their leaders. In 1869, two national organizations (The American Woman Suffrage Association and The National Woman Suffrage Association) were formed to further the cause of women's suffrage. Although these associations were formed for different reasons, the leaders strived for the same thing: voting rights for women. The following resources are examples that teachers can use to begin exploring the Women's Suffrage Movement.

Bumping is the common name for the process of colliding a ship into another ship or celestial object, resulting in a change of position for the ships involved in the collision.
General Bumping
Bumping can occur when a ship comes out of warp in a position "inside" of the geometry of a Station, Stargate, Ship, Sentry gun, Starbase Forcefield, or other object. The bumping produced can be severe, launching ships at hundreds to even thousands of meters per second away from the other object.
Bumping in Battle
Bumping a targeted ship is common, and typically used to push a ship away from a Stargate to be outside of the maximum jump range (2,500 meters away from the stargate), away from a station to be outside of its docking radius (500 meters), or away from the direction the ship is traveling to prevent it from warping to a celestial object.
POS bowling is an example of an infamous bumping strategy.
EVE's Physics Engine does not calculate damage for collisions, even ships as small as frigates. Frigates can slam into capital ships without negative consequences.
How to
To bump another ship, you can;
 - Set your ship to approach the other ship at high velocity through the right click menu, typically with a MicroWarpdrive running. The MWD increases both speed and mass, making collisions more violent.
 - Manually steer your ship to collide with another ship.

On June 1, 2023, Mercure Forbes Global Properties became a patron of the Palais Niel to support the preservation of its architectural and historical heritage with an exceptional dinner, in the company of celebrated French chef Thierry Marx. The event raised funds for the renovation of the entire palace.
A local partnership for heritage preservation
An emblematic jewel of Toulouse's historical heritage, the Palais Niel has been the hub of the French Army in Occitanie since 1999. Considered one of the most prestigious residences built during the 19th century, the Palais Niel only opens its doors to the public on Heritage Day.
To restore the Palais Niel to its former glory, the Fondation du Patrimoine launched a sponsorship campaign a few months ago. This restoration program aims to finance work on the Palais with the help of people committed to safeguarding our architectural heritage.
A true reflection of our culture and history, our architectural and historical heritage helps to create the identity that unites us as a community. By participating in this sponsorship, Mercure Forbes Global Properties confirms its commitment to preserving the testimonies of the past and passing on our rich heritage to future generations.
Since the Palais Niel is based in Toulouse, this partnership was an obvious choice for our group.
This evening at the Palais Niel was an opportunity to showcase our heritage at the heart of a Haussmann-style military building, unique of its kind in Toulouse. Indeed, the Palais Niel boasts typical Second Empire architecture, with classical and Renaissance elements adorning its facades. With the help of partners who love history and architectural heritage, this project will give the Palais a real facelift.
It's a great opportunity for history buffs and architecture enthusiasts to meet and exchange ideas, as well as those involved in the noble cause of heritage preservation.
To make this event as symbolic as it was unique, the Fondation du Patrimoine imagined a gastronomic meal prepared by renowned French chef Thierry Marx, assisted by the best army cooks in Occitanie and young people from Toulouse's hotel schools. The dinner provided an opportunity to delight our partners with refined, elegant cuisine in keeping with our Group's DNA.
We would like to extend our warmest thanks to all the organizers of this evening, as well as to all those who work daily to preserve our rich historical heritage.

RSA key generation is of great concern for implementation of RSA cryptosystem on embedded system due to its long processing latency. In this paper, a novel architecture is presented to provide high processing speed to RSA key generation for embedded platform with limited processing capacity. In order to exploit more data level parallelism, Residue Number System (RNS) is introduced to accelerate RSA key pair generation, in which these independent elements can be processed simultaneously. A cipher processor based on Transport Triggered Architecture (TTA) is proposed to realize the parallelism at the architecture level. In the meantime, division is avoided in the proposed architecture, which reduces the expense of hardware implementation remarkably.

Doodling while listening actually increases retention of memory, LiveScience reports. A new study shows that subjects who "mindlessly" sketched while listening to a not-so-interesting phone message remembered key facts 29% more than others instructed to just listen. "It helps to keep us on track with a boring task," a researcher affiliated with the study said.
"If someone is doing a boring task, like listening to a dull telephone conversation, they may start to daydream," the researcher continued. "Daydreaming distracts them from the task, resulting in poorer performance. A simple task, like doodling, may be sufficient to stop daydreaming without affecting performance on the main task."


text: A novel DNA-based hybrid catalyst comprised of salmon testes DNA and an iron(III) complex of a cationic meso-tetrakis(N-alkylpyridyl)porphyrin was developed. When the N-methyl substituents were placed at the ortho position with respect to the porphyrin ring, high reactivity in catalytic carbene-transfer reactions was observed under mild conditions, as demonstrated in the catalytic enantioselective cyclopropanation of styrene derivatives with ethyl diazoacetate (EDA) as the carbene precursor. A remarkable feature of this catalytic system is the large DNA-induced rate acceleration observed in this reaction and the related dimerization of EDA. It is proposed that high effective molarity of all components of the reaction in or near the DNA is one of the key contributors to this unique reactivity. This study demonstrates that the concept of DNA-based asymmetric catalysis can be expanded into the realm of organometallic chemistry.

This is another chance to use one of my favorite approximations ever! I first offered it as an answer to a question about how deep a platform diver will go into the water. Now is the chance to use it again!
Issac Newton developed an expression for the ballistic impact depth of a body into a material. The original idea was expressed for materials of approximately equal densities when the ballistic body is moving fast enough for the target material to behave as a fluid (think cannon ball into dirt, meteorite into lunar regolith, etc). For a human body into snow, we can assume it will behave in a granular enough fashion.
The human body has a density of roughly $985 kg/m^3$. Using the two limits for the density of snow provided in another answer to this question, snow has a density between $300$ and $900 kg/m^3$. Let's assume the characters are 5 feet tall (you can easily change the number used, it's not a complicated formula). This gives us two limiting expressions:
$$d = 5 \times 985/300 = 16.4~\text{feet}$$
$$d = 5 \times 985/900 = 5.5~\text{feet}$$
So it really would depend on the actual density of the snow, but if you assume that it starts out around $300 kg/m^3$ and can reach a maximum of $900 kg/m^3$, we can assume that the final depth will be close to the same as assuming the average value as $600 kg/m^3$ which would give:
$$d = 5 \times 985/600 = 8~\text{feet}$$
That will give you a pretty good idea of the penetration depths over that range of densities. These numbers are all pretty close to what is given assuming the ideal deceleration given by this answer.
If you want to do a much more complicated analysis of penetration depth, check out the other, more detailed answer to the platform diver question. There it is actually shown that the penetration depth approaches this Newtonian approximation pretty well! It is also interesting to note that the penetration depth does not depend on the impact velocity/original height. Assuming one is going "fast enough" for the material to behave like a fluid, the expression seems to hold.

Nice theoretical answers (I can certainly appreciate them, I'm a mathematician). But why delve into theory when experiment is available? In this video you can see a skier jump from more than 200 feet and get head first into the snow, without a helmet.
The video starts with the aftermath, if you want to see the jump right away fast forward to about 1 minute into it.

About 50 years ago in Reader's Digest there was an article about a Soviet airplane pilot who bailed out at high altitude. He fell into a snow-filled ravine and survived. If the angle of the snow is high enough it is no big deal. At Squaw Valley I have seen skiers do drops that might have been 100 feet. If the landing is steep enough it is OK. It is "flat landings" that will get you.
Rock climber Lynn Hill fell 100 feet onto a dirt slope. She not only survived, she recovered completely.
Stunt men do quite high jumps onto airbags. 100 feet onto 20 feet of snow seems possible, but I wouldn't try it if I had any alternative.


Irish immigrants have been remembered at an event in the US state of Utah celebrating the 150th anniversary of the 'Golden Spike', the moment when the First Transcontinental Railroad was completed.
The railway connected the east and west coasts of the United States and was finished on 10 May, 1869.
An estimated 10,000 Irish immigrants worked on the railroad.
Many of them were veterans of the US Civil War and made up at least half of the workers from the Union Pacific railway company.
They worked alongside a mix of Mormons, other European immigrants and recently emancipated African Americans to construct the line from the east.
Many Irish also worked alongside the 15,000 Chinese immigrants who were the main workforce building the line from Sacramento, California to Promontory Summit, Utah.
A ceremony was held in Utah to mark the 150th anniversary of the railroad's completion.
The event was addressed by the Irish Ambassador to the US, Daniel Mulhall.
He said he was proud and honoured to mark the enormous role played by Irish immigrants in the building of the transcontinental railroad.
Irish Ambassador to the US, Daniel Mulhall, addressing the crowd
"Theirs was a magnificent contribution to the making of modern America," he said.
The US President Donald Trump has paid tribute to the workers who built the transcontinental railroad.
In a statement he said: "We honor the undaunted efforts of the people who made this innovation possible, including workers of Irish and Chinese descent, as well as freed slaves, Native Americans, Civil War veterans, and Latter-day Saints."


what does pheasant taste like
Many people like the idea of eating pheasant because it is seen as a somewhat exotic dish. If you have never eaten it before, are you curious about it? Do you ever think to yourself, what does pheasant taste like?
Pheasant is a type of poultry and is fairly similar in texture and taste to chicken, or turkey. Just like chicken and turkey, it has a combination of both white and dark meat. Pheasant has very little natural fat, so when you cook it, you have to be careful not to let it become too dry, otherwise, it will be bland, tasteless, and tough. But, with the right recipe, if cooked with care, the pheasant can taste absolutely delicious and leave you salivating for more.
Pheasant is best cooked on the bone, with butter and seasonings slipped under the skin, in order to give you a soft, moist and tender dish. Later on in this article, we will look at one or two recipes and methods of cooking pheasant in order to guide you with preparing it in the most delectable way.
If you called up a gourmet foodie and asked, "What does pheasant taste like?" The reply will be that while pheasant may taste similar to chicken, its true flavor is more like game meat, with a smokey flavor. Wild pheasant has a fairly strong, aromatic flavor. It has quite a distinctive taste.
If you have ever cooked turkey, you will know that it takes a long time to cook to perfection. I remember my Mom cooking turkey every year for the holidays. The aroma that wafted through the house as the turkey took its time slow-roasting in the oven made us all walk around with our tongues hanging out, nagging for just a quick taste. But my Mom was adamant, saying "Good food takes time to prepare. When it's ready, the wait will be worth it."
She was so right about that. And when wondering what pheasant tastes like, the same rule of thumb applies to cooking it. Slow roasting on medium heat, with just the right seasonings and sauces, will give you the ultimate melt-in-your-mouth taste of perfectly cooked pheasant.

Is Pheasant Healthy to Eat?
Pheasant is considered by nutritionists to be an extremely healthy source of protein. With our frenetic lifestyles today, many people often tend to choose the easy way out, eating a lot of fast foods, processed meats, rich dairy products, and foods high in trans-fats.
It is no secret that making a habit of eating these foods and following this type of diet is a sure way to cause damage to your arteries. There is more and more emphasis today on the importance of following a healthy diet, and the benefits of living a healthy lifestyle.
If you are wondering what pheasant tastes like, you might also like to know that making it a regular part of your diet has many health benefits. It is very lean, making it low in saturated fats. Unlike certain red meats, pheasant will not clog your arteries with fatty deposits. If you suffer from high cholesterol, you can safely allow pheasant to appear regularly on your table.
What Do Pheasants Eat?
what does pheasant taste like
When trying to answer the question, what does pheasant taste like, it is helpful to look at what pheasants themselves eat? I remember an old favorite television advert, from my childhood, for a certain brand of frozen chicken. The slogan was a simple, but highly memorable one. The reason that they taste so good, is because they eat so well. The same principle would apply to pheasants.
In the wild, pheasants eat fruit, seeds, insects, and even small mammals. Farm-reared pheasants are usually fed a healthy diet of mixed grains, corn, and seeds. They are not fed a fatty diet and are not given any meat to eat. The result is that pheasant is a healthy source of lean protein.
In addition to its protein value, pheasant meat is also rich in vitamins B-6 and B-12. It contains essential minerals such as selenium and potassium and is low in sodium. All-in-all, pheasant is not only an exotic and alluring dish. It is also a healthy and nutritious choice.
Can You Eat Pheasant Eggs?
Pheasant eggs are full of healthy nutrients. They are very rich in protein and amino acids and contain high levels of vitamins B and D. There are many delicious ways to cook these eggs, either on their own or as valuable ingredients in other dishes.
What is the Best Way to Cook Pheasant?
Before actually cooking your pheasant, it is necessary to clean it very well. If you buy from a reputable butcher, it should have already been hung for a few days to ensure that the meat is soft and tender.
Your butcher should also have made sure that your bird has been plucked clean and does not have any stray feathers. When you unwrap it before cooking, even if it looks clean, it is recommended to wash it well by rinsing thoroughly under cold running water. Remember to rinse the inside cavity well, too. You will also want to dry it carefully, in order to prevent the juices from being too watery when you cook it.
Should You Cook Pheasant in the Oven, or on the Stove Top?
You will achieve the best results from slow-roasting your pheasant in the oven at a medium temperature of about 330-350 degrees Fahrenheit. Any hotter than that and your bird will dry out. If you attempt to cook pheasant on the stovetop, the heat of the flame will be too intense and it will not cook evenly. The outside will be hard and dry, while the inside might be under-done.
How Should You Prepare the Pheasant?
what does pheasant taste like
My favorite recipe is so simple and straightforward, but oh so scrumptious! I honestly believe that a recipe does not have to be complicated and intricate, and long and involved, in order to be good. In fact, it is often the simplest and easiest recipes that yield the best results. An added bonus to this recipe is the fact that you literally only dirty two dishes in your kitchen.
 - 1 whole pheasant
 - 3 cups of water
 - 3 tablespoons coarse salt
 - 1 tablespoon sugar
 - 2 bay leaves
 - 2 tablespoons good quality olive oil or softened butter
 - A little maple syrup
 - A sprinkle of freshly ground black pepper
 - Fresh thyme
 - Cut up carrot sticks
 - 1 whole onion, peeled
First, soak the bird in brine. Make the brine by boiling the water, salt, bay leaves, and sugar. Cover and leave to cool completely. When cool, pour the brine over the bird and place it in the fridge for about 8 hours, or overnight.
Hint: if you like nice, crispy skin, remove the bird from the brine and leave it uncovered in the fridge for another 4-6 hours.
Take the pheasant out of the fridge and, while it reaches room temperature, preheat your oven to at least 400 degrees. Rub the bird well with olive oil or softened butter. Try to slip some under the skin as well. This will give you lovely golden, crispy skin. Sprinkle freshly ground black pepper and drizzle very lightly with maple syrup.
Stuff the cavity with the onion, carrot sticks and fresh thyme. Place in a roasting pan and roast uncovered in the oven on high for only fifteen minutes. Take the dish out of the oven, and turn the temperature down to 330-350 degrees. You can leave the oven door slightly ajar to speed up the cooling process. Put the bird back in the oven and roast slowly, also uncovered, for another 30-45 minutes, or until the juices run clear. Take it out of the oven and let it stand for about 10 minutes before carving and serving.
What Does Pheasant Taste Like When Cooked in a Slow Cooker?
The beauty of the recipe given above is that it is easily adapted to slow-cooking. However, you will need more liquid. Follow all the instructions as above, but before placing in the slow-cooker, brown your bird lightly in a pan with a little hot oil, to give it an appetizing color. Put the pheasant into the slow cooker. You can also add some vegetables, like potatoes and pumpkin or baby marrows. Now you will need some liquid to ensure that it doesn't dry out. Take 3-4 cups of good quality chicken stock. Add a generous splash of sherry. Cover the cooker and allow it to cook on low for about 8-10 hours.
How Do You Carve A Pheasant?
Carving a pheasant is much the same as carving a chicken. The trick is to use a very sharp knife. Place your fork in the centre of the breast and slice downwards in a short quick motion. The meat should come away from the bone. If the breast pieces are very large you can slice them up into smaller pieces. Now cut off the wings, and separate the legs and thighs. Serve with a selection of vegetables to suit your taste.
You are now ready to pour yourself a glass of your favorite wine, and tuck in and enjoy a mouthwatering, healthy meal!

Swan song
From Wikipedia, the free encyclopedia
Jump to: navigation, search
For other uses, see Swan song (disambiguation).
"The singing swan" (1655) by Reinier van Persijn.
The swan song (in ancient Greek: κύκνειον ᾆσμα) is a metaphorical phrase for a final gesture, effort, or performance given just before death or retirement. The phrase refers to an ancient belief that swans (Cygnus spp.) sing a beautiful song in the moment just before death, having been silent (or alternatively, not so musical) during most of their lifetime. This belief, whose basis in actuality is long-debated, had become proverbial in Ancient Greece by the 3rd century BC, and was reiterated many times in later Western poetry and art.
Origin and description[edit]
In Greek mythology, the swan was a bird consecrated to Apollo, and it was therefore considered a symbol of harmony and beauty and its limited capabilities as a singer were sublimated to those of songbirds.
Aesop's fable of "The Swan Mistaken for a Goose" incorporates the swan song legend thus: "The swan, who had been caught by mistake instead of the goose, began to sing as a prelude to its own demise. His voice was recognized and the song saved his life."[1] There is a subsequent reference in Aeschylus' Agamemnon from 458 BC. In that play, Clytemnestra compares the dead Cassandra to a swan who has "sung her last final lament". Plato's Phaedo records Socrates saying that, although swans sing in early life, they do not do so as beautifully as before they die. Aristotle also noted that swans "are musical, and sing chiefly at the approach of death". By the third century BC the belief had become a proverb.[2][3]
Ovid mentions it in "The Story of Picus and Canens": "There, she poured out her words of grief, tearfully, in faint tones, in harmony with sadness, just as the swan sings once, in dying, its own funeral song."[4] The swan was also described as a singer in the works of the poets Virgil and Martial.[citation needed]
The most familiar European swan, the Mute Swan (Cygnus olor), although not actually mute, is neither known for musicality nor to vocalize as it dies. This has led some to criticize swan song beliefs since antiquity, one of the earliest[5] being Pliny the Elder: in 77 AD, Natural History (book 10, chapter xxxii: olorum morte narratur flebilis cantus, falso, ut arbitror, aliquot experimentis), states: "observation shows that the story that the dying swan sings is false." Peterson et al. note that Cygnus olor is "not mute but lacks bugling call, merely honking, grunting, and hissing on occasion."[6]
However, the Whooper Swan (Cygnus cygnus), a winter visitor to parts of the eastern Mediterranean, does possess a 'bugling' call, and has been noted for issuing a drawn-out series of notes as its lungs collapse upon expiry, both being a consequence of an additional tracheal loop within its sternum. This was proposed by naturalist Peter Pallas as the basis for the legend. Both mute and whooper swans appear to be represented in ancient Greek and Egyptian art.[3][5]
The Whooper Swan's nearest relatives, the Trumpeter and Tundra Swans, share its musical tracheal loop. Zoologist D.G. Elliot reported in 1898 that a tundra swan he had shot and wounded in flight began a long glide down whilst issuing a series of "plaintive and musical" notes that "sounded at times like the soft running of the notes of an octave".[7]
Post-classical cultural references[edit]
Chaucer wrote of "The Ialous swan, ayens his deth that singeth."[8] Leonardo da Vinci noted "The swan is white without spot, and it sings sweetly as it dies, that song ending its life."[9]
In Shakespeare's The Merchant of Venice, Portia exclaims "Let music sound while he doth make his choice; Then, if he lose, he makes a swan-like end, Fading in music."[10]
The well-known Orlando Gibbons madrigal "The Silver Swan" states the legend thus:
"The Swan Song" ("Schwanengesang") is the nickname of the 1733 Baroque Concerto written by Georg Philipp Telemann: Concerto in D minor for oboe, strings and continuo.[11] The concerto of Telemann begins with a sad part (adagio) later a glad part (allegro), the singing of the swan itself, another sad part (death), and finally a hopeful end.
According to the Oxford English Dictionary, the English phrase "swan song" or "swan-song" borrows from the German schwanen(ge)sang or schwanenlied.[12] The Scottish cleric John Willison, in one of his Scripture Sermons, 1747, proposes a verse from Psalm 48 as a "swan-song" for the faithful.[13]
Samuel Taylor Coleridge made comic use of the legend when he quipped ironically:
Tennyson's poem "The Dying Swan"[14] is a poetic evocation of the beauty of the supposed song and so full of detail as to imply that he had actually heard it:
Tennyson's poem was an inspiration for the ballet The Dying Swan created for Anna Pavlova in 1905, to the music Le cygne from The Carnival of the Animals by the French composer Camille Saint-Saëns.
Finnish composer Jean Sibelius's tone poem The Swan of Tuonela, in a famous solo, uses a cor anglais to play the dying song of the legendary swan of Tuonela.
In Carmina Burana by Carl Orff, there is a tenor solo called Olim Lacus Colueram about a swan who laments his end and looks back at his glorious days by the lake.
In his song '3005' rapper Childish Gambino references it with the line "And when I'm long gone, whole crew sing a swan song"
The season finale of Season 5 of the show Supernatural the episode is titled Swan Song. It refers to Sam Winchester's last act of averting the apocalypse, by jumping into the cage with Lucifer to save the world.
By extension, "swan song" has become an idiom referring to a final theatrical or dramatic appearance, or any final work or accomplishment.[15] It generally carries the connotation that the performer is aware that this is the last performance of his or her lifetime, and is expending everything in one magnificent final effort.[original research?]

Water + Mandarin Experiment
- A bucket of water
- A mandarin
Method: fill a bucket with water and put mandarin in and see what happens.
My experience: So first we put the mandarin in the water and it was struggling to float(it still did though). Next we peeled the mandarin and put it in. It sank to the bottom like a rock. Then we put the peels in and they floated. Then my friends put the piece onto the peel and put it in the water it floated. I found out that for mandarins the skin is what keeps the buoyant.

Politics and tax morale. the role of trust, values, and beliefs, in shaping individual attitudes towards tax compliance.
MetadataShow full item record
Traditional models of tax evasion cannot explain why most people comply with their taxes. It has been proposed that taxpayers may have an intrinsic motivation (or willingness) to comply with taxes - Tax Morale. Empirical studies found that trusting government, upholding religious beliefs, and supporting democratic regimes, increase individual Tax Morale. Based on those results and drawing from related literature in Political Science, this study tests the role of trusting government institutions delivering public goods to taxpayers, ideological beliefs, individual support for political regimes, and upholding post-materialist values, on Tax Morale. Results for individuals living in democratic countries show a positive relationship between trust in government institutions and upholding democratic values on Tax Morale; a negative relationship between upholding ideological (conservative) beliefs and Tax Morale, and no relationship between upholding post-materialist values and Tax Morale. Results for individuals living under non-democratic regimes differ in some respects; whereas support for democracy is related with higher Tax Morale, other results - trust in government and ideological beliefs - differ from theoretical expectations. Overall, higher trust in government increases willingness to comply with taxes, and support for democracy elicits higher Tax Morale.

text: Property market dynamics depend on changes in long run equilibrium and on impediments to adjustment towards equilibrium. One of the most important aspects of property market dynamics is often attributed to the activities in the mortgage market. However, many impediment factors, such as changes in family status, education, neighborhood effects and job relocation, are often unobservable from micro household-level data. Since these omitted variables contribute to moving decisions and therefore to sale and default decisions, utility functions for sale and default are correlated through these unobservable variables; thus, the IIA assumption of the widely used Multinomial Logit Model (MNL) is violated. Under such circumstances, econometric theory suggests that the Nested Logit Model (NMNL) is a better choice, which obviates the limitation of MNL by allowing correlation in unobserved factors across alternatives. This paper empirically investigates the omitted household mobility characteristics problem in mortgage termination, and tests NMNL against MNL. Using loan level micro data, we find significant correlation between sale and default due to omitted borrower mobility characteristics. Our simulations find that NMNL out performs MNL in out-of-sample prediction.

Benefits Of Onsite Childcare
Benefits of Onsite Childcare
An onsite childcare facility refers to a place where daycare for a baby is offered either directly at the workplace or next to it. Different from other kinds of childcare that are generally offered in someone's house, onsite childcare is offered in a workplace facility. Through incorporating onsite childcare into a business, the following advantages are gotten.
1. Flexible work schedules
Having an onsite childcare basically means that when employees are placed on varying schedules, it is not going to affect their childcare situations. For instance, if the business needs to change work hours so as to better cater for its consumers or lessen overhead costs, having an onsite childcare facility ensures that this process is easier for both the company and the employees.
2. Enhances employment opportunities
A business with onsite a childcare facility has an additional benefit to provide would-be recruits that another company might not have. If you are looking for the best employees that you can get, offering onsite childcare places your business ahead of other people. Actually, companies that offer onsite childcare have better retention rates.
3. Increases focus
Having a childcare situation miles away that is far away from the place of work can become an enormous distraction to workers if complications arise. However, when the business offers childcare for workers onsite, parents can easily deal with any arising issues with their children directly and then get back to their jobs. Furthermore, onsite childcare also eases the worker's minds as they know that their kids are close to them, reducing employee distraction.
4. Boosts loyalty
When a business opens a childcare facility onsite while offering a reasonable charge to the employees, it assists to build and boost loyalty. It essentially becomes an advantage of employment, just like health insurance.
However, an onsite childcare might appear impersonal and institutional. A child might not have the continuity of childcare from one person, thereby making forming attachments and bonds difficult.
Benefits Of Onsite Childcare
1 User Submission
 1. I agree, that offering childcare for employees in the organization would be a added benefit for any employee. Any parent would love to be able to go see their child during lunch breaks to assure they are ok and be able to return to work without the stress or concerns of wondering if their child is ok. I also believe that onsite child care facitlities would reduce absentism, lateness and increase employess productivity, so I am all for childcare serivice for employees being an added benefit.

Measuring Client Performance with Endpoint Analytics
We've all heard reports from end-users that their device is too slow or takes too long to do something. Reports from users, however, can be subjective, so how can we certify the results and get tangible metrics to support the claims? With Microsoft Intune and Endpoint Analytics is how.
Whether it be a laptop that takes so long to boot you can make a coffee and drink it or whether it's a logon process that is so slow it's time for the user to take their next break already, we've all seen and heard of performance issues before. As IT or as someone making financial decisions about hardware purchases for end-users, knowing that what you have or what you buy is good is important and for that you need data and we can use Endpoint Analytics in Microsoft Intune exactly for this purpose.
What is Endpoint Analytics?
Simply put, Endpoint Analytics is a feature we can enable in Microsoft Intune to collect data from client systems registered with Microsoft Intune running Windows 10 to understand how they behave and perform.
Once enabled, we can see how devices perform against performance baselines and you can either use the baseline recommended by Microsoft or specify your own.
What information does Endpoint Analytics provide?
Endpoint Analytics in Microsoft Intune provides information about boot time, sign-in and logon times. The information is broken down into how long each portion of the start-up was attributed to the device vs. time attributed to Group Policy processing for Hybrid Azure AD Joined devices allowing you to see the impact of your Active Directory Domain Services Group Policy Objects.
With data collected by Endpoint Analytics, we can see how devices perform across various metrics and report it per device type or even for individual devices.
With the information collected, Endpoint Analytics allows you to display it overall for your whole organisation, per-device model, or per individual device. With these breakdowns, you can see whether a specific device model has a performance issue to address or whether it is only impacting specific users and devices so you can work on targeted fixes and remediation.
When it comes to remediation and fixing issues, Endpoint Analytics provides information such as which start-up processes are causing delays so that you can look into them and try to fix them.
Proactive remediations provides some pre-defined scripts you can deploy for fixing common issues and the Recommended software section provides you with a summary report of what modern management features are being used such as Cloud identity, Cloud management, and Windows Autopilot.
How do I implement it?
Implementing Endpoint Analytics in Microsoft Intune is as simple as creating and assigning a Device Configuration Profile to enable the feature on devices. Once enabled, you simply wait for device metrics to start coming through.
Get started with Microsoft Intune, Endpoint Analytics, and modern management
If you need to get your devices in shape, manage them better, faster, or more easily. Maybe you've got an on-premises management solution and you want to move to a cloud-based modern management alternative.
Speak to us at Arcible about how we can help you implement Microsoft Intune and to find out more.


Top 5 Frost-Free Refrigerators and why should we buy them
None of us are guests to seeing ice form in our freezers. This happens due to the uneven circulation of cooling air in the freezer. As soon as cool air meets hot or humid air, frost is formed. Frost-Free refrigerators as the name implies prevents the formation of frost or ice. This is due to a small convection (electrical fan) that evenly distributes cold air avoiding frost to form.
Advantages of frost-free refrigerators:
 1. The main advantage of frost-free refrigerators is that you don't have to manually clean the fridge to thaw and drain out the ice every few months. The frost-free fridge avoids the formation of ice saving you time and effort.
 2. It maintains the maximum freshness of food, preventing it from getting spoilt due to ice crystals forming on stored food.
 3. Storage can be utilized to the maximum as there is no frost to create an interference with space.
 4. Neglecting regular frost formation in the fridge could cause a problem with the fridge's lifespan. As frost-free refrigerators prevent frost from forming, they have a longer lifespan.
Here is our list of the top 5 Frost-Free Refrigerators to buy:

Framingham Railroad StationEdit profile
Framingham Railroad Station built is 1885 is an historic Boston and Albany Railroad station located in Framingham, Massachusetts. Designed by noted American architect H. H. Richardson, it was one of the last in his series of Northeastern United States railroad stations. Today, it has been converted into a Brazilian steakhouse, though much of the external structure remains intact. Additionally, a small building on the site has been converted into a bank ATM. Amtrak and the Massachusetts Bay Transportation Authority use the nearby Framingham (MBTA station).
The station was listed on the National Register of Historic Places in 1975.


Help width widthSegments, heightSegments, and Height Map size on PlaneGeometry
Hi all,
I am in the process of building a Plane that has segments that I am changing their vertice height based on a height map.
Everything is technically working but my results do not represent exactly what I have in my change map.
NOTE: The height map image is a grayscale 100x100 PNG.
I would love if someone could help understand what line segments I should be using and based off that, what the size of my heightmap should be.
Here is the basic code below…
var planeSize = 100;
//init
function init() {
 generatePlane();
}
function generatePlane() {
 var container = $('#change-map');
 var scene = new THREE.Scene();
 var camera = new THREE.PerspectiveCamera( 50, container.width()/container.height(), 0.1, 8000 );
 camera.name = "Camera";
 var renderer = new THREE.WebGLRenderer();
 renderer.setSize( container.width(), container.height() );
 container.append( renderer.domElement );
 var img = new Image();
 img.onload = function () {

 textureLoaded();

 };
 img.src = "img/height-map-100.png";
 function textureLoaded() {
 var data = getHeightData(img, 1);

 var geometry = new THREE.PlaneGeometry( planeSize, planeSize, planeSize * .5, planeSize * .5 );
 var material = new THREE.MeshBasicMaterial( { wireframe: true } );
 var plane = new THREE.Mesh( geometry, material );
 for ( var i = 0; i<plane.geometry.vertices.length; i++ ) {
 plane.geometry.vertices[i].z = data[i] * .1;
 //; 3
 }
 plane.name = "Plane";
 scene.add( plane );

 }

 scene.add( camera );
 camera.position.z = planeSize * 1.5;
 var animate = function () {
 requestAnimationFrame( animate );
 renderer.render(scene, camera);
 };
 animate();
}
function getHeightData(img,scale) {

 if (scale == undefined) scale=1;

 var canvas = document.createElement( 'canvas' );
 canvas.width = img.width;
 canvas.height = img.height;
 var context = canvas.getContext( '2d' );

 var size = img.width * img.height;
 var data = new Float32Array( size );

 context.drawImage(img,0,0);

 for ( var i = 0; i < size; i ++ ) {
 data[i] = 0
 }

 var imgd = context.getImageData(0, 0, img.width, img.height);
 var pix = imgd.data;

 var j=0;
 for (var i = 0; i<pix.length; i +=4) {
 var all = pix[i]+pix[i+1]+pix[i+2];
 data[j++] = all/(12*scale);
 }

 return data;
}
Think I may of figured it out… The line segments needs to be planeSize - 1 and the height map needs to be the same size as the planeSize, so 100x100.
If anyone can verify or clarify or dispute this, please do so :slight_smile:

Drought-hit Sussex reservoir given help to raise level
Low rainfall has forced the government to grant a drought order to South East Water to help it protect a reservoir in Sussex.
Water levels in Ardingly reservoir dropped to 12% in November.
The reservoir is partly used to top up the River Ouse if its water flow falls below a set level.
However, this set level has been temporarily reduced in the hope the reservoir will re-establish itself before Spring 2012.
Ardingly reservoir serves more than 65,000 homes across large parts of East and West Sussex.
The drought order, granted by the Department for Environment, Food and Rural Affairs (Defra), is valid until 31 March.
Lee Dance, head of water resources for South East Water, said: "We rely on winter rainfall to recharge our underground water sources and reservoirs to take us through to the warmer spring and summer months.
"The Sussex area has seen an increase in rainfall during December, which has certainly helped the current water resource situation, but it by no means solves the problem."
The minimum flow in the River Ouse is normally set to 20m litres a day. The drought order has temporarily reduced this to 5m.


text: We demonstrate a novel motion correction of 3D magnetic resonance fingerprinting (MRF) using spiral projection k-space trajectory. The motion was corrected using rigid motion parameters extracted from a whole-brain navigator obtained every 7s of imaging. Firstly, we optimized the trajectory ordering in simulation and selected the acquisition scheme that allowed the best navigator for motion correction. Secondly, we applied this scheme to invivo data in healthy subjects scanned first without motion and then while performing a motion paradigm. Our motion correction improved the correlation of motion-corrupted data with motionless data by over 20% for both T1 and T2.

organize the nested table as an index-organized table (IOT). If the
NESTED_TABLE_ID column is a prefix of the primary key for a given parent row, Oracle physically clusters its children rows together. So, when a parent row is accessed, all its children rows can be efficiently retrieved. When only parent rows are accessed, efficiency is maintained because the children rows are not inter-mixed with the parent rows.
Figure 5-6 shows how the storage table works when the nested table is in an IOT. The storage table groups the values for each nested table within a nested table column. In Figure 5-6, for each nested table in the
NT_DATA column of the parent table, the data is grouped in the storage table. So, all of the values in nested table
A are grouped together, all of the values in nested table
B are grouped together, etc.
In addition, the
COMPRESS clause enables prefix compression on the IOT rows. It factors out the key of the parent in every child row. That is, the parent key is not repeated in every child row, thus providing significant storage savings.
In other words, if you specify nested table compression using the
COMPRESS clause, the amount of space required for the storage table is reduced because the
NESTED_TABLE_ID is not repeated for each value in a group. Instead, the
NESTED_TABLE_ID is stored only once per group, as illustrated in Figure 5-7.
In general, Oracle Corporation recommends that nested tables be stored in an IOT with the
NESTED_TABLE_ID column as a prefix of the primary key. Further, prefix compression should be enabled on the IOT. However, if you usually do not retrieve the nested table as a unit and you do not want to cluster the child rows, do not store the nested table in an IOT and do not specify compression.
For nested tables stored in heap tables (as opposed to IOTs), you should create an index on the
NESTED_TABLE_ID column of the storage table. The index on the corresponding ID column of the parent table is created by Oracle automatically when the table is created. Creating an index on the
NESTED_TABLE_ID column enables Oracle to access the child rows of the nested table more efficiently, because Oracle must perform a join between the parent table and the nested table using the
For large child-sets, the parent row and a locator to the child-set can be returned so that the children rows can be accessed on demand; the child-sets also can be filtered. Using nested table locators allows you to avoid unnecessary transporting of children rows for every parent.
You can perform either one of the following actions to access the children rows using the nested table locator:
Set membership queries are useful when you want to search for a specific item in a nested table. For example, the following query tests the membership in a child-set; specifically, whether the location
home is in the nested table
phones_ntab, which is in the parent table
Oracle can execute a query that tests the membership in a child-set more efficiently by transforming it internally into a semi-join. However, this optimization only happens if the
ALWAYS_SEMI_JOIN initialization parameter is set. If you want to perform semi-joins, the valid values for this parameter are
HASH; these parameter values indicate which join method to use.
You can perform DML operations on nested tables. Rows can be inserted into or deleted from a nested table, and existing rows can be updated, by using the appropriate SQL command against the nested table. In these operations, the nested table is identified by a
TABLE subquery. The following example inserts a new person into the
people_reltab table, including phone numbers into the
phones_ntab nested table:
INSERT INTO people_reltab values ( 0001, name_objtyp( 'john', 'william', 'foster'), address_objtyp( '111 Maple Road', 'Fairfax', 'VA', '22033'), phone_ntabtyp( phone_objtyp('home', '_PHONE_'), phone_objtyp('work', '_PHONE_'))) ;
The following example inserts a phone number into the nested table
phones_ntab for an existing person in the
people_reltab table whose identification number is
INSERT INTO TABLE(SELECT p.phones_ntab FROM people_reltab p WHERE p.id = '0001') VALUES ('cell', '_PHONE_') ;
To drop a particular nested table, you can set the nested table column in the parent row to
NULL, as in the following example:
Once you drop a nested table, you cannot insert values into it until you recreate it. To recreate the nested table in the
phones_ntab nested table column object for the person whose identification number is
0001, enter the following SQL statement:
You also can insert values into the nested table as you recreate it:
UPDATE people_reltab SET phones_ntab = phone_ntabtyp(phone_objtyp('home', '_PHONE_')) WHERE id = '0001' ;
DML operations on a nested table lock the parent row. Therefore, only one modification at a time can be made to the data in a particular nested table, even if the modifications are on different rows in the nested table. However, if only part of the data in your nested table must support simultaneous modifications, while other data in the nested table does not require this support, you should consider using
REFs to the data that requires simultaneous modifications.
For example, if you have an application that processes purchase orders, you might include customer information and line items in the purchase orders. In this case, the customer information does not change often and so you do not need to support simultaneous modifications for this data. Line items, on the other hand, might change very often. To support simultaneous updates on line items that are in the same purchase order, you can store the line items in a separate object table and reference them with
REFs in the nested table.
An attribute of a collection cannot be a collection type (either varray or nested table). In other words, you cannot have collections within collections. Oracle allows only one level of direct nesting of collections. However, an attribute of a collection can be a reference to an object that has a collection attribute. Thus, you can have multiple levels of collections indirectly by using
For example, suppose you want to create a new object type called
person_objtyp using the object types described in "Column Object Storage", which are
phone_ntabtyp. Remember that the
phone_ntabtyp object type is a nested table because each person may have more than one phone number.
To create the
person_objtyp object type, issue the following SQL statement:
CREATE TYPE person_objtyp AS OBJECT ( id NUMBER(4), name_obj name_objtyp, address_obj address_objtyp, phones_ntab phone_ntabtyp);
To create an object table called
person_objtyp object type, issue the following SQL statement:
CREATE TABLE people_objtab OF person_objtyp (id PRIMARY KEY) NESTED TABLE phones_ntab STORE AS phones_store_ntab ;
people_objtab table has the same attributes as the
people_reltab table discussed in "Column Object Storage". The difference is that the
people_objtab is an object table with row objects, while the
people_reltab table is a relational table with three column objects.
Now you can reference the row objects in the
people_objtab object table from other tables. For example, suppose you want to create a
projects_objtab table that contains:
You can use
REFs to the
people_objtab for the project leads, and you can use a nested table collection of
REFs for the team. To begin, create a nested table object type called
personref_ntabtyp based on the
person_objtyp object type:
Now you are ready to create the object table
projects_objtab. First, create the object type
projects_objtyp by issuing the following SQL statement:
CREATE TYPE projects_objtyp AS OBJECT ( id NUMBER(4), title VARCHAR2(15), proglead_ref REF person_objtyp, description CLOB, team_ntab personref_ntabtyp);
Next, create the object table
projects_objtab based on the
CREATE TABLE projects_objtab OF projects_objtyp (id PRIMARY KEY) NESTED TABLE team_ntab STORE AS team_store_ntab ;
people_objtab object table and the
projects_objtab object table are in place, you indirectly have a nested collection. That is, the
projects_objtab table contains a nested table collection of
REFs that point to the people in the
people_objtab table, and the people in the
people_objtab table have a nested table collection of phone numbers.
You can insert values into the
people_objtab table in the following way:
INSERT INTO people_objtab VALUES ( 0001, name_objtyp('JOHN', 'JACOB', 'SCHMIDT'), address_objtyp('1252 Maple Road', 'Fairfax', 'VA', '22033'), phone_ntabtyp( phone_objtyp('home', '_PHONE_'), phone_objtyp('work', '_PHONE_'))) ; INSERT INTO people_objtab VALUES ( 0002, name_objtyp('MARY', 'ELLEN', 'MILLER'), address_objtyp('33 Spruce Street', 'McKees Rocks', 'PA', '15136'), phone_ntabtyp( phone_objtyp('home', '_PHONE_'), phone_objtyp('work', '_PHONE_
