text: Gene expression differences between divergent lineages caused by modification of cis regulatory elements are thought to be important in evolution. We assayed genome-wide cis and trans regulatory differences between maize and its wild progenitor, teosinte, using deep RNA sequencing in F1 hybrid and parent inbred lines for three tissue types (ear, leaf and stem). Pervasive regulatory variation was observed with approximately 70% of ∼17,000 genes showing evidence of regulatory divergence between maize and teosinte. However, many fewer genes (1,079 genes) show consistent cis differences with all sampled maize and teosinte lines. For ∼70% of these 1,079 genes, the cis differences are specific to a single tissue. The number of genes with cis regulatory differences is greatest for ear tissue, which underwent a drastic transformation in form during domestication. As expected from the domestication bottleneck, maize possesses less cis regulatory variation than teosinte with this deficit greatest for genes showing maize-teosinte cis regulatory divergence, suggesting selection on cis regulatory differences during domestication. Consistent with selection on cis regulatory elements, genes with cis effects correlated strongly with genes under positive selection during maize domestication and improvement, while genes with trans regulatory effects did not. We observed a directional bias such that genes with cis differences showed higher expression of the maize allele more often than the teosinte allele, suggesting domestication favored up-regulation of gene expression. Finally, this work documents the cis and trans regulatory changes between maize and teosinte in over 17,000 genes for three tissues.

ThreadStart delegate, ParameterizedThreadStart delegate, and SynchronizationContext class
ThreadStart delegate - MSDN
The simplest way to create a thread is to instantiate the Thread class. The Thread constructor takes a delegate argument. The ThreadStart delegate points to a method containing your logic. For example:
Thread t1 = new Thread (new ThreadStart(LengthyLogic));
public void LengthyLogic ()
{
 // Logic code
}
ParameterizedThreadStart delegate - MSDN
When you start a thread, sometimes you need to pass in some data for processing. .NET 2.0 provides a new delegate, ParameterizedThreadStart, which takes a parameter of type object. The class has a new overload function Thread.Start. It allows you to specify the value to be passed into the thread. This approach is simple, but is not type-safe. Example:
Thread t1 = new Thread(new ParameterizedThreadStart(LengthyLogic));
// Use the overload of the Start method that has a parameter of type Object.
t1.Start(myData);
static void LengthyLogic(object data)
{
 // Logic code
}

Using applications domains
Exam objective: Create a unit of isolation for common language runtime in a .NET Framework application by using application domains
(Refer System namespace)
Create an application domain
See MSDN
An application domain is a division of a process into multiple parts. Applications running in different application domains are as isolated as they would be in different processes. So they cannot access memory in another application domain. However, if native code is run, it can gain unlimited access to the whole process, which includes other application domains.
Application domains are easier to maintain and are faster because it is easier to communicate between application domains than between processes. An application domain can hold multiple assemblies.
To create an application domain, you must at least supply a name for the new application domain:
 AppDomain ad = AppDomain.CreateDomain("Name");
Use AppDomain.CurrentDomain to get the application domain the calling thread is using.
Load assemblies into an application domain
See MSDN
It is possible to execute an assembly by name using AppDomain.ExecuteAssemblyByName:
 AppDomain ad = AppDomain.CreateDomain("Name");
 ad.ExecuteAssemblyByName("aname, Version=1.0.0.0, Culture=neutral, PublicKeyToken=a9b8c7d6");
Or use AppDomain.ExecuteAssembly to supply a path to the assemby:
 AppDomain ad = AppDomain.CreateDomain("Name");
 ad.ExecuteAssembly(@"c:\path\to\file.exe");
Unload an application domain
See MSDN
It is not possible to unload assemblies from the default application domain. However if an assembly is loaded in a different application domain, you can unload the whole application domain which includes all assemblies in that application domain.
To unload an application domain, use the static AppDomain.Unload function:
 AppDomain ad = AppDomain.CreateDomain("Name");
 AppDomain.Unload(ad);
Configure an application domain
See MSDN
The most likely reason to modify the application domain configuration, is to restrict certain permissions to limit the damage if an attacker exploits vulnerabilities in an assembly.
An example is to run an assembly in the Internet Zone. The Internet Zone has limited permissions. To do this create a Zone Evidence and supply it as a parameter when creating the Application Domain:
 object [] myEvidenceTypes = {new Zone (SecurityZone.Internet)};
 Evidence myEvidence = new Evidence(myEvidenceTypes, null);
 AppDomain ad = AppDomain.CreateDomain("Name", myEvidence); // Pass the Evidence when creating the App. Domain
 ad.ExecuteAssembly(@"c:\path\to\file.exe");

It is also possible to execute only one assemby in an Application Domain with different permissions;
 object [] myEvidenceTypes = {new Zone (SecurityZone.Internet)};
 Evidence myEvidence = new Evidence(myEvidenceTypes, null);
 AppDomain ad = AppDomain.CreateDomain("Name");
 ad.ExecuteAssembly(@"c:\path\to\file.exe", myEvidence); // Pass the Evidence in the ExecuteAssembly function
Except Evidence, you can also use the AppDomainSetup class to set other properties.
 AppDomainSetup ads = new AppDomainSetup();
 ads.ApplicationBase = @"c:\Test";
 ads.DisallowCodeDownload = true;
 AppDomain ad = AppDomain.CreateDomain("Name", null, ads); // use null as second parameter for default Evidence
Retrieve setup information from an application domain
See MSDN
Use the SetupInformation property of an AppDomain to read the settings from that application domain;
 AppDomainSetup ads = AppDomain.CurrentDomain.SetupInformation;
 Console.WriteLine(ads.ConfigurationFile);
 Console.WriteLine(ads.ApplicationName);
Configuration, diagnostic, management, and installation
Exam objective: Embedding configuration, diagnostic, management, and installation features into a .NET Framework application
Topics
Configuration management
Configuration management is used here in a restricted sense. It refers to the adaptation of an application to a specific execution environment or user. This is usually done thru the use of configuration files that specify the run time parameters of the application. The typical example of such configuration information is the connection string used to locate and connect to the application database

Question 80: Prayer At The Earliest Hour
Question: In order to prove the merit of praying at the earliest hour some scholars have said that Imam az-Zaman (a.s.) prays at this time and then people who pray at this hour their prayer is also accepted by Allah due to the barakah (bounty) of the prayer of Imam (a.s.).
But we also know that different areas fall in different time zones. Leave alone the different countries sometimes one country has many times zones. In this condition only the prayer of the people of that area is with Imam (a.s.) where he is praying. Apart from this the Prayer timings of other people cannot be same as that of Imam (a.s.). How can we solve this problem?
Answer: Those who have presented this argument to prove the merit of praying at the earliest hour, they mean to say that the prayer which is prayed the earliest hour those prayers are equal to the prayers with Imam (a.s.) because he (a.s.) also prays at the earliest hour. And it is due to this equal value, the prayers of others are also accepted by Allah.
This is in no way connected to the matter of time zones etc. In other words it does not mean that prayers have to be performed at one single time. Rather it denotes the fact that all the Prayers have been performed at their respective earliest hours, which every person performs according to his time zone.

'Smoke from Australian fires will not have direct impact on Nepal'
January 18, 2020 09:24 AM NPT
By: Aditi Baral
KATHMANDU, Jan 18: Amid forecast of the US-based National Aeronautics and Space Administration (NASA) that the smoke from Australia's fires will make a full circuit around the world, there are concerns around the world if this would leave impact on other countries as well. Meteorologists and atmospheric scientists in Nepal, however, say there is no need to panic although there are some chances of receiving slightly visible effects in the sky over this Himalayan nation should the fire keep on razing at a dangerous pace.
According to the Metrological Forecasting Division (MFD), there has been no impact of the Australian bushfires on Nepal so far. "Large scale phenomena like Australian bushfires definitely will cause perilous global effects and impact on the global climate. But countries like Nepal that lie far away from the affected region may not be affected directly. However, we might experience less or negligible impact due to climate change that these fires could bring about," said meteorologist Shanti Kandel at the MFD.
Although there has been slight relief with relatively cooler condition and slight rainfall in Australia, reports show that more than 100 fires are still burning in some states like New South Wales and Victoria in Australia.
A recent statement by NASA said that the smoke produced by the Australian fires will make a full circuit around the globe. Satellite images have also shown clouds of smoke formed by the fires traveling beyond the continent, with possibilities of creating their own weather in the form of massive thunderstorms that can later create new fires.
"The smoke from Australian fire will have visible effects in counties of the eastern and western regions but it is less likely to affect countries in the north. So, Nepal will not be affected," said Senior Atmospheric Scientist at ICIMOD Arnico Kumar Panday.
The Australian fire aggravated by climate change has been razing for several months now, prompting global outcry. Unimaginable causalities have been caused by this phenomenon with the burning of an estimated 10 million hectares (100,000 sq km or 15.6 million acres) of bush, forest and parks across Australia. It has also caused an estimated death of one billion animals, death of more than two dozen people including four firefighters and destruction of over 1,400 homes.
As per the reports provided by NASA's research center, the smoke from these fires have somewhat already traveled halfway around Earth, causing haze in the skies of South America and bringing changes to the color gradient of dusk and down. It has also greatly impacted the air quality levels of neighboring nation New Zealand along with reflecting changes in the color patterns of sunrise and sunset.
However, scientists predict that the smoke from the Australian fires might lead to the formation of heavy clouds and rainfall in Nepal. "We might experience gloomy days and excessive rainfall as an impact of the smoke travelling from the Australian fires," Panday further explained.
While the increasing trend of wildfire in recent years has become a serious concern across the world, Nepal itself witnesses about thousands of forest fires every year. According to a report prepared on Wildfire Dynamics in Nepal, the overall recorded wildfire incidences were 35,374 and the burnt area was 1,723,920 hectares from 2000 to 2016. Most of these fires are caused by a long dry spell, windy weather and discarded cigarettes.
Scientists say these forest fires have been creating major impact on the environment by emitting carbon dioxide and other greenhouse gases that continue to warm the surrounding, bringing change to the weather patterns in various places. "Although Australian fires do not have direct effects in Nepal, we have small forest fires every year within the nation that also tend to add up to become a strong reason for air pollution" said research scientist Sameer Mani Dixit.

Non-commutative case: a caveat
Proposition. Let Template:Mvar be the ring of non-commutative real polynomials in Template:Mvar and Template:Mvar. Let Template:Mvar be the principal two-sided ideal generated by Template:Mvar and Template:Mvar the principal two-sided ideal generated by xy + 1. Then I + J = R but IJIJ.
Proof. Observe that Template:Mvar is formed by all polynomials with an Template:Mvar in every term and that every polynomial in Template:Mvar vanishes under the substitution y = − {{ safesubst:_TAG_:Unsubst||$B=1/x}}. Then clearly p = (xy + 1)xIJ. Define a "term in Template:Mvar", as an element of the multiplicative monoid of Template:Mvar generated by Template:Mvar and Template:Mvar, and its degree as the usual degree of the term after the substitution y = x. On the other hand, suppose qJ. Observe that a term in Template:Mvar of maximum degree depends on Template:Mvar otherwise Template:Mvar under the substitution y = − {{ safesubst:_TAG_:Unsubst||$B=1/x}} can not vanish. The same happens then for an element qIJ. Note that the last Template:Mvar, from left to right, in a term of maximum degree in an element of Template:Mvar is preceded by more than one Template:Mvar. (We are counting here all the preceding Template:Mvars. E.g., in x2yxyx5 the last Template:Mvar is preceded by three Template:Mvars.) This proves that p = (xy + 1)xIJ since the last Template:Mvar in the term of maximum degree in Template:Mvar (Template:Mvar) is preceded by only one Template:Mvar. Hence IJIJ.

of data (the grid contents). I see no significant disadvantages over rolling your own matching algorithm, and it simplifies the whole process. – David Gouveia Dec 28 '11 at 14:47
_USER_, that's just a phrase for people who are not too comfortable with Regex. If they decide to solve a problem with regex, they now have two problems: (1) the actual problem they want to solve (2) writing the regex pattern to solve that problem – iamserious Dec 28 '11 at 14:52
Going back to the 'now you have two problems' - Regex will have problems as soon as you have more items than the ASCII printable range, unless your regex processor supports unicode and you can guarantee that certain combinations won't trip the regex NFA compiler up. You could throw together your own DFA (quite easily actually) to match patterns; but regex would be the best way to go while prototyping. – Jonathan Dickinson Dec 29 '11 at 13:57

I can't tell you how the Minecraft one works - although I am sure if you looked at MCP (if you have a legal copy of Minecraft) you could find out.
I would implement this as follows:
 1. Have some disk-based dictionary/hashmap (B+Tree/SQL-Light) - the value would be the item ID of the recipe result.
 2. When a user is crafting something simply find the first row/column with an item INDEPENDENTLY; combine those into an offset.
 3. Find the last row/column with an item, again, independently.
 4. Compute the width and height from the items and add it to the key.
 5. Loop over the range of the bounding box you just computed and append the ID of each item (using your usual for (y) { for (x) }).
 6. Look the key up in the database.
So for example lets say we have two ingredients; X and Y and blanks being *. Take the following recipe:
First we work out the bounding box, yielding (2,0)-(2,2). Therefore our key would look like this [1][3] (1 width, 3 height). Next we loop over each item within the bounding box and append the ID, thus the key becomes [1][3][X][Y][Y] - you then look this up in your dictionary/DB and you will get the result of that recipe.
To explain the independence in step 2 more clearly, consider the following recipe:
The top/left is clearly at 0,0 - however the first item you would typically encounter would be either 0,1 or 1,0 (depending on your loop). However if find the first non-empty column as well as the first non-empty row and combine those co-ordinates you will get 0,0 - the same principal applies to the bottom/right of the bounding box.

Isn't this just the inverse of your other answer? – David Eyk Dec 29 '11 at 23:56
_USER_ (This is my first answer) not really, it is more dependant on a hashmap structure (whether it is bigtable-like or in-memory). The reason I answered again is because I was worried about hash collisions leading to poor performance - at least in a in-memory hashmap. My other answer would work better for more items and an in-memory structure - where this would work better if it was in SQL/etc. – Jonathan Dickinson Dec 30 '11 at 8:52

Pollicization surgery is performed when your child has no thumb or when the thumb hypoplasia is more severe. The operation involves creating a functional thumb by transferring another finger (usually the index) to the thumb position.
 - This may seem drastic because an index finger is being sacrificed. However, since thumb function is crucial to overall hand function, having a three-fingered hand with a thumb will enable your child to have considerably better hand function than a four-fingered hand with no thumb.
 - Surgeons and parents sometimes find that a hand with one thumb and three fingers can actually be quite acceptable in appearance. This operation has an excellent track record and its results are reliable. In cases where the index finger is normal and functional, a very good thumb results.
 - The decision to undergo this procedure depends heavily on the condition of your child's index finger. If the index finger cannot move independently or has other problems, your child's doctor may not recommend pollicization.
If the thumb is completely missing, index pollicization surgery moves the index finger into the thumb position. The index finger is separated at the growth plate, a section of the finger is removed from the hand, and the remaining finger is relocated to where it can serve as a thumb.

"Intelligence without ambition is a bird without wings."
Salvador Dali was a prominent Spanish surrealist painter. Dali was known to be very eccentric and imaginative. He often wore a cape, carried a walking stick, and donned an upturned waxed moustache. He never did anything without great flourish. That is why I am not at all surprised he is credited with this quote.
Being smart is not enough. You must be driven, motivated, and focused. Have you ever engaged with an incredibly bright person who has no drive? Has that person made a difference in the world? Would you consider that person a change agent? Do you use the adjective "successful" to describe this person?
Ambition, therefore, is important, and there are a number of characteristics associated with ambition: persistence, discipline, determination, and creativity. Remember, a bird flying has a much more exciting life that the bird who sits in the nest never to leave.

Modern methods of construction: guidance for building standards verification
Provides guidance to Local Authority verifiers and Certifiers as defined under the Building (Scotland) Act 2003 when assessing building warrant applications and certifying works which use Modern Methods of Construction (MMC).
This document is part of a collection
8. Future Compliance Plan Approach
8.1. A strengthened approach to compliance
The Compliance and Enforcement Expert Review Panel was set up to support the Ministerial Working Group on Building and Fire Safety following the fire at Grenfell Tower and failings in the construction of Edinburgh School Buildings. The Panel's report
highlighted a need to strengthen the Scottish Building Standards system and the Building Standards Futures Board was established in 2019 to oversee this work. The Compliance Plan (CP) is one of the seven work streams being taken forward by the Futures Board.
The CP work stream aims to provide greater assurance that the risk of non-compliance with the building regulations has been minimised. This will be achieved by considering compliance from the inception of a project through to its completion by requiring better evidence and documentation to be provided by the Relevant Person and the people they appoint to undertake the work.
Following support for the proposal during the public consultation which ran from November 2021 to February 2022, the proposals include the creation of a CP for all High Risk Building (HRB) projects by the Relevant Person and their appointed 'Compliance Plan Manager' (a new oversight role acting on behalf of the Relevant Person).
The CP will identify the risks on a project and set out the evidence needed, inspections to be undertaken and the CP Manager will oversee the CP to ensure it is fully discharged. It is expected that the CP Manager on HRB projects will be a suitably qualified and experienced construction professional.
A Compliance Plan Handbook (CPH) will also be developed providing guidance on this new strengthened approach to delivering building regulation compliant buildings in accordance with the approved building warrant plans and details. It is intended this MMC guidance document will be referenced within the CPH to inform and support the verification of buildings using MMC.
There is a problem

Given two bitmap images (two arbitrarily sized two-dimensional matrices of integer values ranging from 0 to some maximum number), I want to determine their maximum overlaps.
An overlap is a relative positioning of the images (a translation of the second image) producing a nonempty intersection on which both images are the same.
For instance, the images $\left\langle \begin{bmatrix}0 & 1\\0 & 1\end{bmatrix}, \begin{bmatrix}1 & 1\\1 & 1\end{bmatrix} \right\rangle$ have overlaps $\{ (1,-1), (1,0), (1,1) \}$, with intersection sizes $1,2,1$, respectively, so only $(1,0)$ is maximal.
It seems to me we can create a fast algorithm based on generalizing suffix trees to "subimage trees", built with a floodfill algorithm.
Is this a viable approach? Is it better than alternatives?
Is this problem discussed in the literature? What is its time complexity?
(My apologies for asking several related questions at once.)

 - $\begingroup$ What I mean is a 2D version of a suffix tree. Instead of mapping each substrings of a string to the positions in the string where they occur, it would map subimages of the original images to the 2D positions where they occur. I'm being vague because I haven't actually tried to implement it. $\endgroup$ Feb 24 at 11:25

For a pair of matrices $A, B$, $B$ maximally overlaps $A$ at a position if and only if certain two rectangular sub-matrices of $A$ and $B$ match.
It is not clear how to use the two-dimensional suffix tree for this problem, because this data structure can only process square sub-matrix matching queries.
An answer is to use the fingerprinting-based algorithm. By generalizing Rabin-Karp algorithm, any rectangular sub-matrix pattern matching query can be answered in constant time.
More specifically, a matrix $A \in \mathbb{Z}^{n \times m}$ is represented by a fingerprint $h(A) = \sum_{i=1}^n \sum_{j=1}^m A_{i,j} X^{i-1} Y^{j-1}$ in two randomly-chosen variables $X, Y$ in a big enough finite field. By pre-computing all "prefix" values of forms $h(A[1:i,1:j])$ and $X^iY^j$, any fingerprint of a rectangular sub-matrix can be computed in constant time.

Ellis Square Parking Garage
Location: Savannah, GA
Client: City of Savannah, Batson-Cook Company
Thomas & Hutton was retained to provide right of way surveys, existing condition surveys, and structural monitoring for the Ellis Square underground parking garage.
Right of way surveys of the square and the adjacent streets were required to clearly define the project limits and allow the planning of critical retaining structures and congested traffic flows. Existing conditions surveys were needed for design.
In addition to the normal challenges encountered in a crowded historic district, the survey team was tasked with locating and mapping all underground utilities. Ground penetrating radar and electromagnetic induction were used to locate more than 15,000 feet of active and abandoned utility lines within roughly a two block area. Designers used detailed 3-D models to carefully plan utility relocations and excavation strategies as they pieced together the complicated dig.
An excavation project of this magnitude posed structural risks to nearby buildings. Thomas & Hutton monitored ground movement during construction. For more than a year, our crews made precise measurements on six baselines watching for alterations around the project area. Data was carefully adjusted for environmental conditions, analyzed for integrity, and compared with control values. Cumulative weekly reports were subsequently generated and provided to structural engineers who then made important stabilization decisions based on the findings.

The role of uric acid in development of renal dysfunction (RD) remains controversial. Earlier studies have reported inconsistent results, possibly because of their varying ability to adjust for confounding. The impact of longitudinal change in uric acid on renal outcome has not been assessed previously. We aimed to study the impact of change in serum uric acid (SUA) as well as baseline SUA on the development of RD.
In a prospective cohort study, we assessed the associations between change in SUA during follow-up, baseline SUA and RD (defined as albumin-creatinine-ratio (ACR) =1.13 mg albumin/mmol creatinine and/or eGFR?

English Language Fellow Justine Flores conducted a 3-hour teacher training at the Future Pioneers Model School in Jericho. There were a variety of teachers who had studied either education or English in attendance. Flores found that these teachers had complementary skills and paired them together to allow for a more dynamic training session.
The Future Pioneers Model School follows a student-centered learning style where teachers encourage their students to try innovative styles of learning. Flores implemented aspects of innovative teaching in her training by taking time to compare the pronunciation of vowels in English and in Arabic. Participants found that this activity helped them improve their English language awareness. At the end of the training participants felt more confident in their teaching abilities.

How to Fill Blank Cells with Value above in Excel (3 Easy Ways)
Have an Excel question? Chat with an Excel Expert!
Sometimes, you may have a dataset where there are empty/blank cells in a dataset that should have been filled with the same value.
Below is a common example where the date is only mentioned one time and all the remaining records for that same date have the date cells blank.
While this type of data may look cleaner (especially when printed), it's not great when you try to use this for calculations or create a Pivot Table using it.
In many cases, you would need to fill these blank cells with the value in the above cell.
How to Fill Blank Cells with Value above in Excel
In this Excel tutorial, I will show you three really easy ways to fill the blank cells with the value above in Excel.
 1. Using Go To Special with a formula
 2. Using Find and Replace with a formula
 3. Using VBA
The tricky part of this entire process is actually selecting the blank cells. Once you have the blank cells selected, there are multiple ways to copy cell values from above.
So let's get started!
Fill Cells with Value Above Using 'Go To Special' + Formula
The first step in filling blank cells from the value above is to select these blank cells. And this can easily be done using the 'Go To Special' option in Excel.
Suppose you have a dataset as shown below and you want to fill all the blank cells in column A with the date from the cell above.
Dataset-to-fill-blank-cells-from-above-cells
Below are the steps to select all these blank cells at one go:
 1. Select the dataset in which you have these blank/empty cells
 2. Hit the F5 key on your keyboard (use + G if you're using a Mac). This will open the 'Go To' dialog box
 3. Click on the Special button.Click-on-the-Special-Button
 4. In the 'Go To Special' dialog box, select the 'Blanks' optionSelect-the-blank-option
 5. Click OK.
The above steps would select all the blank cells in this dataset.
All-blank-cells-are-selected
Now that you have all the blank cells selected, the next step is to fill all these blank cells from the value above.
Follow the following steps to use a formula to copy the value from the cell above:
 1. Enter = (equal to sign). by default, this will enter the equal to sign in the active cell only
 2. Press the up-arrow key. This will select the cell right above the active cellEnter-the-formula-in-the-active-cell
 3. Hold the Control key and press the enter key (Command + Enter if you're using a Mac)
That's it!
The above steps would apply the same formula (which is simply to refer to the cell above) to all the selected blank cells.
Once you have all these blank cells filled, remember to convert the formulas to values.
Note that for this method to work, the cells need to be completely empty. In case there are space characters, the 'Go-To' feature will not consider these as blank cells and these wouldn't be selected.
Fill Cells with Value Above Using 'Find and Replace' + Formula
The above (Go To Special) method works well when you only have the blank cells that you want to fill-down.
But what if you get a dataset where the cells are not really blank (but may have a dash in it or some text such as NA).
In such a case, you can also use the Find and Replace method.
This method works similar to Go To Special, but with an added advantage of being able to select cells based on the value.
With this method, you can select blank cells or you can select cells that have any specific text/value in it.
Let me show you how this would work taking an example of blank cells only.
Suppose you have a dataset as shown below and you want to fill all the blank cells in column A with the date from the cell above.
Below are the steps to select all the blank cells using Find and Replace:
 1. Select the dataset in which you have these blank/empty cells
 2. Hold the Control key and press the F key (or Command + F if you're using Mac)
 3. In the Find and Replace dialog box that opens up, click on the 'Find All' button. This will find all the cells that are blank and you will also see a list of these cells addresses.Click-on-Find-All
 4. Hold the Control key and press the A key (or Command + A if you're using Mac). This will select all these blank cellsSelect-all-blank-cells-using-the-keyboard-shortcut-Control-A
 5. Close the Find and Replace dialog box.
By the end of these steps, you will have all the empty cells selected.
Now, you can use the formula to get the value from the above cell and fill in the blank cells in Excel.
Follow the following steps to use a formula to copy the value from the cell above:
 1. Enter = (equal to sign). by default, this will enter the equal to sign in the active cell only
 2. Press the up-arrow key. This will select the cell right above the active cell
 3. Hold the Control key and press the enter key (Command + Enter if you're using a Mac)
One of the benefits of using Find and Replace it works when you have blank cells that you want to fill, and you can also use it to find and select cells that have specific values.
For example, suppose you have a dataset as shown below where instead of the blank cells, we have dashes instead.
Dataset-that-has-dash-in-empty-cells
To do this, follow the below steps:
 1. Select the dataset
 2. Hold the Control key and press the F key (or Command + F if you're using Mac)
 3. In the Find and Replace dialog box that opens up, enter – (dash) in the 'Find what' field.Enter-Dash-in-Find-and-Replace-Find-what-field
 4. Click on the Find All button. This will find all the cells that have the dash symbol and you will also see a list of these cells' addresses.
 5. Hold the Control key and press the A key (or Command + A if you're using Mac). This will select all these cells
 6. Close the Find and Replace dialog box.
Once you have these cells selected, you can use the formula steps shown above to fill values from cells above (or even full cell values from below/right/left).
Fill Cells with Value Above Using VBA
While these two above methods work perfectly fine, in case you have to do this quite often, you can also use a simple VBA code to get this done.
And if you want to be super-efficient and get this done with a single click, you can add the VBA macro to the Quick Access Toolbar (QAT) and simply click on it to fill the blank cells in the selection with the cell value from the above cell.
Below is the VBA code that will get this done:
Sub FillCellFromAbove()
For Each cell In Selection
 If cell.Value = "" Then
 cell.Value = cell.Offset(-1, 0).Value
 End If
Next cell
End Sub
To use this code, first, select the dataset where you want to copy the value from the above cell, and then run this code.
The above code uses the FOR EACH loop where it goes through each and every cell in the selection. As soon as it finds a cell that's empty (checked using the IF statement), it copies the value from the cell above (done using OFFSET).
In this specific example, you may notice that
Note: In case you want to save a workbook that has the macro code, you need to save it in the .XLSM (macro enabled) format.
The best thing about using this VBA code is that it doesn't require you to convert the formulas into values. With this method, you get static values only. This makes it a really efficient method (of all the three covered in this tutorial).
There are however two things you need to know when using VBA to get fill the blank cells with a value from the above cell:
 - You can't undo this once you have run the macro code. So make sure you create a backup copy before you run the VBA code
 - If you have a huge dataset (thousands of rows with multiple columns), this is likely to slow down your system. Since the VBA code above goes through and analyzes each cell, it takes more time than the remaining two methods. When using with a few hundred (or even a few thousand data points), you'll likely not notice any difference in speed.
To use this VBA macro code, you need to put it into a regular module.
So these are three ways you can use to fill the blank cells with data from the cell above it.

Temple, Texas Facts:
- County: Bell
- Coverage Area (Total): 65.3 sq. miles
- Elevation: 719 ft.
- Population: 66,102
- Cities/Towns covered in local Names and Numbers Phone Book: Bartlett, Belton, Heidenheimer, Holland, Little River-Academy, Moffat, Moody, Oenaville, Rogers, Salado, Temple, Troy, Zabcikville
Temple was founded in 1881 by the Gulf, Colorado and Santa Fe Railroad and incorporated in 1882. It was originally named Temple Junction after a railroad official named Bernard Moore Temple. Local residents nicknamed the town "Tanglefoot" due to the combination of muddy streets and liquor consumption making it difficult to walk through. After the town's incorporation, The Temple Academy private school was organized and public school was established in 1884.
Temple became known as one of the leading medical communities in the Southwest with the establishment of the Santa Fe Hospital (1891), King's Daughters Hospital (1897), and Scott and White Hospital in 1904. By 1900, there were more than 7,000 residents, which more than doubled to over 15,000 by 1930. In 1942, Temple added another dimension to its medical status with the opening of the Veterans Administration. By the 1970s, due in part to its extensive agricultural production, Temple was named the site for the state offices of the U.S. Soil Conversation Service.
Temple maintains a variety of attractions including:

Research the Geese's Habits and Behaviors
If you want to learn how to hunt geese without decoys, the first step is to research the geese's habits and behaviors. Geese are social creatures and they typically travel in flocks.
They also have a hierarchy within the flock, with a dominant male leading the way. When it comes to feeding, geese prefer to graze on grasses and aquatic plants. They will also eat insects, crayfish, and small amphibians.
To successfully hunt geese without decoys, you need to understand their behavior and patterns. One of the best times to hunt geese is early in the morning, when they are just waking up and starting to move around.
Another good time to hunt is in the evening, just before they roost for the night. If you can find a spot where geese are feeding, that's also a good place to set up your hunt.
When you're out hunting, pay attention to the direction of the wind. Geese have a very strong sense of smell, so they will be alerted to your presence if you're downwind of them. If you can position yourself upwind of the geese, they won't be able to smell you and you'll have a better chance of getting close enough for a shot.
Camouflage is also important when hunting geese. Wear clothing that blends in with your surroundings, and use a blind or ground cover to conceal your movement. If the geese see you, they will likely take off and it will be much more difficult to get a shot.
Patience is key when hunting geese. Even if you're in the perfect spot and everything is lined up perfectly, it can still take awhile to get a shot. Be patient and wait for the right opportunity. If you move too soon, you'll likely scare the geese away and won't get a chance to take a shot.
If you follow these tips, you'll have a better chance of success when hunting geese without decoys. Researching the habits and behaviors of geese is the first step to becoming a successful hunter.
Know the Right Place to Hunt
If you want to be a successful goose hunter, you need to know where to find the birds. Obviously, this isn't as simple as it sounds since geese are constantly on the move in search of food.
Fortunately, there are a few things you can do to give yourself the best possible chance of finding geese. Here are a few tips on how to find the right place to hunt.
Scout early and often:
One of the best things you can do is scout the area you plan to hunt before the season starts. This will give you a good idea of where the birds are feeding and will allow you to set up your blind or decoys in the right spot. Once the season starts, you should continue to scout so you can stay ahead of the birds.
Pay attention to weather patterns:
Another helpful tip is to pay attention to weather patterns. Geese are more likely to be in certain areas depending on the time of year and the weather conditions.
For example, in the spring they'll be in areas with fresh green grass, and in the winter they'll be in areas with open water. By paying attention to the weather, you can have a better idea of where the birds will be and when they'll be there.
Check out the local farmer's fields:
One of the best places to find geese is in the local farmer's fields. Farmers typically don't mind if you hunt on their property, as long as you ask for permission first. Geese like to eat the same things that farmers grow, so it's a great place to find them.
Pay attention to the time of day:
Another helpful tip is to pay attention to the time of day. Geese are more active in the morning and evening, so that's usually when they'll be feeding. If you can, try to hunt during these times so you have a better chance of finding birds.
Now that you know a few tips on how to find the right place to hunt, you're well on your way to becoming a successful goose hunter. Just remember to scout early and often, pay attention to weather patterns, and check out the local farmer's fields. If you do these things, you'll be sure to find plenty of geese.
Utilize Natural Blinds
One piece of advice that all waterfowl hunters can agree on is the importance of utilizing natural blinds. A natural blind is simply an area of natural vegetation that conceals you from the view of approaching ducks or geese.
While many hunters choose to build their own man-made blinds out of materials like straw or reeds, utilizing a natural blind can be just as effective – if not more so. Here are a few tips on how to hunt geese without decoys by utilizing natural blinds:
- Look for areas of dense vegetation near likely feeding or resting areas for waterfowl. cattails, bulrush, and tall grasses are all good choices.
- Avoid areas that have been recently disturbed, such as areas that have been recently mowed or where there is a lot of human activity.
- Once you've found a promising spot, take some time to scout the area and make sure there are no potential hazards that could give away your position, such as branches that could brush against you or leaves that could crackle underfoot.
- When you're ready to hunt, approach the blind quietly and take care to avoid making any noise that could alert the birds to your presence.
- Once you're in position, stay still and wait for the birds to come to you. resist the urge to move, even if it's just to adjust your position – the slightest movement can be enough to startle waterfowl and send them flying off.
Geese are wild creatures and are very difficult to hunt without the use of decoys. However, there are a few things that you can do to increase your chances of success. One of the most important things is to wear camouflage.
When selecting a camo pattern, make sure to choose one that will work well in the environment where you plan to hunt. If you're hunting in a marsh, for example, you'll want a camo pattern that has a lot of brown and green in it. And if you're hunting in a snow-covered field, white will be an important color in your camo.
In addition to wearing camouflage, there are a few other things you can do to increase your chances of success when hunting geese.
First, make sure to do your homework and know where the geese are likely to be. Second, use a good quality call to lure the geese in. And finally, be patient and wait for the perfect shot.
Consider Different Types of Calls
In order to be a successful goose hunter, it is important to consider different types of calls. There are many different types of goose calls on the market, and each has its own unique sound.
Some calls are designed to mimic the sound of a particular species of goose, while others are designed to mimic the sound of a particular type of call. It is important to experiment with different types of calls in order to find the one that is most effective for your hunting situation.
One type of call that can be effective for goose hunting is the inline call. This type of call is inserted into the hunter's mouth and allows the hunter to control the sound that is emitted. The hunter can vary the sound by changing the position of the call in their mouth, and by controlling their breath.
Another type of call that can be effective for goose hunting is the diaphragm call. This type of call is placed over the hunter's nose and mouth, and the hunter controls the sound by controlling their breath. Diaphragm calls are available in different sizes, and the hunter should choose a size that is comfortable for them to use.
Goose calls can also be effective for hunting other types of waterfowl, such as ducks. Duck calls are available in different styles, and the hunter should choose a style that is comfortable for them to use.
In order to be successful when hunting geese, it is important to consider different types of calls. By experiment with different types of calls, the hunter will be able to find the one

Three-Body Invariant Manifold Transition with Electric Propulsion
The advantageous combination of dynamical systems theory of three-body models with Electric Propulsion to design novel spacecraft mission in multi-body regimes has been investigated. Combining the advantages of Electric Propulsion with respect to propellant requirements and low-energy ballistic trajectories existing in the three-body model, multi-body planetary tours can be designed. The employment of power constrained Electric Propulsion at the solar distance of Uranus is enabled by the use of Radioisotope Thermoelectric Generators. This provides continuous availability of sufficient electrical power.
Not only a planetary tour of the Uranian system orbiting consecutively Oberon, Titania, Umbriel, Ariel and Miranda is designed, but also the required interplanetary trajectory transporting the spacecraft from the Earth to Uranus. Both the interplanetary trajectory and the planetary tour are computed in different three-body environments, where the start of the interplanetary phase is assisted by a high energy launch to limit the transfer time.
It is demonstrated that a feasible mission can be designed both in terms of transfer time and propellant mass requirement, with a scientifically interesting character. The spacecraft is unstable captured by the five moons for different periods of time, with a stable Uranian orbit as a final state.

Glass shape influences how quickly we down alcohol
Glass shape influences how quickly we down alcohol
Washington: How quickly you consume down an alcoholic drink may depend on the shape of the glass you're drinking from, a new study has suggested.
For the study, Dr Angela Attwood and colleagues from Bristol's School of Experimental Psychology recruited 160 social drinkers aged 18-40 with no history of alcoholism to attend two experimental sessions.
During one session they were asked to drink either lager or a non-alcoholic soft drink from either a straight-sided glass or a curved 'beer flute'.
They found that the participants were almost twice as slow when drinking alcohol from the straight-sided glass as compared to the curved glass.
However, there was no difference in drinking rates from the glasses when the drink was non-alcoholic.
Importantly, the degree of this error seemed to be associated with the speed of drinking – the participants who tended to show the greatest error in their halfway judgments tended to show the greatest changes in drinking rate.
Therefore, slower drinking rates is likely to have positive impact on the individual and also at a population level.
"Due to the personal and societal harms associated with heavy bouts of drinking, there has been a lot of recent interest in alcohol control strategies. While many people drink alcohol responsibly, it is not difficult to have 'one too many' and become intoxicated. Because of the negative effects alcohol has on decision making and control of behaviour, this opens us up to a number of risks," Dr Attwood said.
"People often talk of 'pacing themselves' when drinking alcohol as a means of controlling levels of drunkenness, and I think the important point to take from our research is that the ability to pace effectively may be compromised when drinking from certain types of glasses," she added.

- owe (v.)
- Old English agan (past tense ahte) "to have, own," from Proto-Germanic *aiganan "to possess" (cf. Old Frisian aga, Old Norse eiga, Old High German eigan, Gothic aigan "to possess, have"), from PIE *aik- "to be master of, possess" (cf. Sanskrit ise "he owns," isah "owner, lord, ruler;" Avestan is- "riches," isvan- "well-off, rich").
Sense of "to have to repay" began in late Old English with the phrase agan to geldanne literally "to own to yield," which was used to translate Latin debere (earlier in Old English this would have been sceal "shall"); by late 12c. the phrase had been shortened to simply agan, and own (v.) took over this word's original sense.
An original Germanic preterite-present verb (cf. can, dare, may, etc.). New past tense form owed arose 15c. to replace oughte, which developed into ought (v.).

Traumatic Grief and Unconfirmed Death
An unconfirmed death refers to a situation in which the family does not know for sure whether the person has died and has no guarantee that the person will return. Such situations can occur during war, through kidnapping, or during natural disasters such as floods or earthquakes. In cases such as these, children may continue to hope, imagine, or plan on the person's return, and feel guilty or disloyal when engaging in rituals such as celebrating holidays without the missing person. The lack of certainty surrounding the death can be confusing and can mean that traditional—and potentially comforting—rituals such as a funeral cannot be observed. Unconfirmed death can also lead to traumatic grief reactions in children.
Unconfirmed death can be traumatic for children and teens, in part because the lack of certainty about the death makes it difficult for them to complete many of the tasks of normal bereavement. This publication offers caregivers advice on helping children deal with the complex emotions that arise when the death of family member or other important person in a child's life is suspected, but not confirmed.

1. Introduction
Currently, composites are one of the most promising materials for use in new technologies [1,2]. The most widespread are laminates, fibrous (reinforcing component - the fibrous structure), and filled materials (the reinforcing component - particles). In turn, compared with laminated composites, cylindrical composites (fibers) have more compact structure, which is beneficial for device miniaturization [3,4]. Such composites are usually modeled by periodic sets of cylinders made of one material (filler) and placed in the second material (matrix). The calculation of effective parameters of the composite medium is based, as a rule, on the solution of the problem for the single cylinder (inclusion) in the surrounding external field and subsequent averaging procedure [5]. To be more precise, for the description of corresponding inclusions it is necessary to use the equations considering interactions of all possible fields: electromagnetic, elastic and thermal.
The surface and nonlocal effects start to play a significant role for the inclusions of size about one nanometer. Therefore, in general there is a need to solve the integro-differential equations. In our work, an average diameter of inclusions is assumed to be tens of nanometers and, thus, we can restrict ourselves by differential equations. Moreover, we analyze the case where the electrical properties of composites can be considered independently of the elastic ones. That is, it is sufficient to find the electric potential by means of the Laplace equation. In a classic work by Rayleigh [6], the electric potential was computed for a conducting composite consisting of a periodic array of inclusions (cylinders and spheres). More complex core-shell structures, which have appeared in recent years, allow one to improve the desired properties of composites. However, these structures complicate the determination of their properties even in the elementary cases [7-9].
Future prospects for the development of composites are associated with the finding of non-smooth fillings of untypical shapes. As already well known [9], the presence of peaks or edges of a filling leads to the appearance of singularities in the electric field that has a strong impact on the effective permittivity. The numerical calculation of such structures is not an easy task and requires skilled techniques for its solution (see, e.g. [9,10]). In this study, we investigate the possibility to control the dielectric constant by changing the distance between the boundaries of the different layers (shells). We consider the electric potential in the medium consisting of cylindrical inclusion in which one more cylinder is placed (see, Fig. 1). In other words, two dielectric cylinders are considered. If the cylinders have no common points, then the solution of an electrostatic problem can be found in [9,11]. Summing it up, this paper examines a cylinder completely immersed inside another one. A case of intersecting cylinders remains unexplored.
Note that due to the analogy between the stationary electric and thermal fields, the effective thermal capacity of a composite with inclusions in the form of eccentric cylinders can be determined by the same procedure.
2. The solution of the general problem
2.1. The problem statement
As a starting point, we consider an electric field in the system illustrated in Fig. 1. Inclusion consists of two eccentric circles of radii of r\ and r2 which centers are located at distance d from each other. The surfaces of
Fig. 1. The mutual arrangement of two dielectric cylinders
circles are Sij2. To describe electrostatic field, we employ a Cartesian coordinate system (x,y). By ei, e2 we denote dielectric permeability of circles and dielectric permeability of external space (matrix) by e0.
Similarly, we will use the subscripts 1,2 to identify quantities related to circles and subscript 0 for the matrix parameters. In the absence of any subscript, the expression is fulfilled in all environments. The intensity of the external electric field is supposed to be a constant vector of length E. In the solution of our problem it is necessary to find the potential u, which satisfies the two-dimensional Laplace equation:
Am = 0, (1)
and is continuous at the interfaces S1j2 together with the normal component of the electric displacement:
duo dui dui du2
uo Si = ui s1, ei—— = e2—— , ui S2 = U2 S2, ei —— = . (2)
on on on on
S1 Si S 2 S2
Moreover, at the distance far from the inclusion, the potential u tends to the potential of the external field:
u0 ^ —E0(x cos y + y sin y). (3)
Here, n is normal to the surfaces Sij2, E0 is the electric stress, and y is an angle between the external field and the x-axis. Because of the lack of symmetry, the solution of Eqs. (1)-(3) depends on the angle y.
If we introduce the potential U that tends to U0 = x + iy at large distances from the inclusion, then the desired potential u can be expressed in terms of U as:
u = —E0(ReU cos y + ImU sin y).
(4)
Further, it is reasonable to switch to a bipolar coordinate system (a, ¡3) [12] associated with the Cartesian by the relations:
x + iy = c tanh If we define the parameters ai, a2 and c from:
a + i3
(5)
cosh a,-
— r2 + ( —l)j d2 2jd :
c = r1 sinh a1,
(6)
then the circles' boundaries are the coordinate lines a = aij2. The solution of the stated problem will be sought in the form:
2

Uo = x + iy + ao„e
n(a-2a 1
Ui = £ [alnen(a-2ai) + blne U2 = £ b2nein^
na
n1'
n=i
ein^' (7)
The Fourier coefficients ajn and bjn in Eq. (7) are uniquely determined by taking into account boundary conditions. In particular
aon = 2c(-1)n, An = £iOn±1, Sn = £i±£l e2n(a2-ai). (8)
An + 1 £o On — 1 £2 — £l
The coefficients ain and blj2n have a similar form. For simplicity we do not write down explicit equations for these coefficients.
2.2. The Maxwell-Garnett theory
Let us now discuss the influence of the cylinder eccentricity on the effective characteristics of the medium. First, we consider the main principles of the Maxwell-Garnett theory for the set of identical inclusions randomly arranged in the matrix. Each of these inclusions consists of n dielectric layers with

"Waioli Mission Hall stands as a major monument of Hawaiian architectural history, the primary inspiration for the Hawaiian double-pitched hipped roof so widely popularized by C. W. Dickey in the 1920s. Built by the Reverend William P. Alexander, Dickey's grandfather, the plaster walls of the frame structure repose beneath a sprawling roof and encircling lanai. The roof, originally thatched, was shingled in 1851. Similarly, the freestanding, ohia-framed belfry at the rear of the mission was of thatch construction, but most likely received a covering of shingles in the same year. The form of the twenty-five-foot-high belfry drew upon a long British and American colonial tradition. Common in its day, today it stands as the sole surviving example of its type in Hawaii.
This was the third church building on the site, with the earlier thatched edifices falling prey to fire and storms. It remained a center for worship until the completion of Waioli Huiia Church (ka44) in 1912, when it became a community hall for the church, a function it still serves today. The building has been thrice restored: in 1921 by Hart Wood, in 1978 by Bob Fox, and again in 1993, following Hurricane Iniki, by Designare Architects."

We are well aware of the fact that the Earth's crust is exceptionally hot. However, it is obvious that the rocks and all the constituents inside the Earth's crust also contain extremely hot temperatures. In a recent case, scientists discovered the hottest rock and recorded its extreme temperature as well. The rock was first discovered in 2011 by the University of Western Ontario and surprisingly small zircon grains were being discovered too. Zircons are very reliable substances, and when given high-temperature conditions, they have the capability to form crystals. But it was not obvious at that time whether there were actually zircon grains or not being found. However, later studies endorsed this fact through and through, proving that the discovery was made right.
Not only did they find this in one specific location, but they came upon it in more than one place, i.e., in different locations throughout the earth's crust, and it turned out that they were warmed up to the core with a temperature of about 4298 degrees Fahrenheit, or 2370 degrees Celsius. "The biggest implicit argument is that we're receiving a much better understanding of how hot these effects melt rocks are, which constituted when the meteorite touched the surface, and it gives us a much better idea about the history of the melt and how it cooled in this particular crater," said Gavin Tolometti, a postdoctoral student at the University of Western Ontario. "The majority of the surviving evidence, such as glass pieces and impact melt samples, were discovered near the crater bottom," he noted. "By extending this information to additional impact craters, researchers may be able to find more evidence of the temperature conditions seen in less thorough investigations of other craters."
A lot of analyses have been conducted to prove the authenticity of this research, like the one that shows that about 36 million years ago, these rocks were transmuted into meteorites and that this happened due to their hot temperature, which caused the melting. This is evidence that the recorded heat of the rocks was authentic and well researched. "It might be a step forward in attempting to comprehend how rocks have been affected by impact craters over the whole solar system," Tolometti observed. Despite these findings, the researchers are still on their way to exploring more techniques and procedures to study the rocks and find some amazing discoveries like the one recently discovered about the hottest rock in the earth's crust. The study has been published here.

Parameters Necessary for Analyzing Thermal Bioassaysby Robert D. Smith, Ensign; United States Navy,
Serial Information: Journal of the Sanitary Engineering Division, 1972, Vol. 98, Issue 6, Pg. 973-985
Document Type: Journal Paper
A series of bioassay experiments concerning the effects of heated water on white perch have shown that, for water temperatures ranging between 82°F (300.9°K) and 97°F (309.3°K), the lethal effects on a white perch being held at any temperature within that range will occur within the first 36 hrs of exposure. This is shorter than the time period prescribed in general by the standard bioassay procedure. Three parameters are given which more completely describe the pattern of mortality. Investigation has shown that: (1) A relationship exists between the temperature at which mortalities of the white perch are incipient and the temperature at which the body of the fish is functioning and (2) the lethal effects on white perch caused by extreme water temperatures are independent of the rate of temperature increase.

Ritual de sobrevida
In Cuba, the Virgin of Charity or Virgen de la Caridad del Cobre is venerated as their nation's patroness and holds the additional title of "Virgin for Cuban Independence." For Afro-Cubans who practice Santeria she is syncretized with the orisha Ochún. Does the image refer to the ritual crowning of the Virgin Mary, a Catholic ritual that often takes place in May, hence the expression Queen of May?
This handmade book is decorated with cotton wool and a sun and moon are added on the back. Behind the moon is a crown, decorated with a cross and a silver oval. The front sides depict a snake and the Vigía lamp, held by a hand that peeks out from behind the right cover.

I was using while (true) to control some code that was supposed to run for a designated amount of time. I noticed the processor load spike by 40-60%. As there was no input to slow down execution, it was tearing through the code in the while loop and repeating as quickly as possible. Looked up a way to slow it down and discovered sleep(# of milliseconds in Windows.h. Is there either: a) a better way to go about controlling the rate of execution; or b) a cross-platform variant of sleep(time)?
Generally sleep() is not recommended. The alternative is to use events and signals to control the flow of a program. The reason for this is that programs should not be 'hanging' themselves but instead allow the user to do other tasks while the program is waiting for some new event to process.
while(true) is a brutal way to pause a program as you've seen. Depending on how you've implemented your 'timer' the actual sleep time could have been dependent on processor speed and the actual hardware you use instead of the equivalent seconds you programed it for.
All this said, there are still applications for a sleep() function and it is much better than most while variants. Since sleep functions make use of the system time they are OS specific but most OS do have some sort of sleep() function. It's just a matter of finding the right header.

Import duplicate company data to use for testing [AX 2012]
Updated: February 1, 2013
In Microsoft Dynamics AX 2009, the duplicate company feature was used extensively to copy data from one company to another. The feature was also used to build development or test environments, and deployment scenarios that moved data from one environment to another. However, this feature became obsolete in Microsoft Dynamics AX 2012.
We recommend that you use the Microsoft Dynamics AX data export and import feature to support scenarios that previously required the duplicate company feature.
Company, or DataArea, can no longer be used as a data security boundary. Because of changes that were made to the organization model in Microsoft Dynamics AX 2012, data is no longer related to a company or legal entity in a simple relationship that is defined by setting the SaveDataPerCompany metadata property of a table to Yes. Because data relationships are now defined through the Relations metadata property, it is not easy to duplicate all data that is related to a legal entity. Therefore, it may not make business sense to duplicate the data that is related to a legal entity. For example, we created organizational hierarchies in which legal entities and business units have a complex relationship. There is no parent/child relationship between business units and legal entities. Therefore, the duplication of business units based on legal entities in the system is erroneous.
Follow these steps to use an existing legal entity as a template for other legal entities.
 1. Create a legal entity to use as a template.
 For more information, see Create or modify a legal entity.
 2. Set all configuration data for the legal entity.
 3. Use the Microsoft Dynamics AX data export and import feature to export the legal entity to a.dat file, such as TMP.dat.
 1. Before you export data, you must create a definition group.
 For more information, see Create definition groups for import and export.
 2. To export configuration data, include the following table groups: Reference, Parameter, Group, Framework, and Miscellaneous.
 To export master data, you must also include the tables that are in the Main table group.
 Do not include the tables that are in the Transaction, Transaction header, Transaction line, Worksheet, Worksheet header, and Worksheet line table groups. These tables include transaction data.
 For a detailed list of all the tables in a table group, see Table group reference.
 4. In the new environment, create new legal entities, and then import the.dat file that you created into each entity individually.
 Shared and per-company data is imported. When other legal entities are subsequently imported into the new legal entities, the shared data is merged.
 For more information, see Import data from another instance of Microsoft Dynamics AX.
You can use the Microsoft Dynamics AX data import and export feature to import and modify transaction data. However, it can be difficult to create a duplicate environment for transaction data if the SaveDataPerCompany property of tables is set to No. Instead, we recommend that you use the backup and restore functionality in Microsoft SQL Server to build demo environments in which minor configuration changes can be made to illustrate specific Microsoft Dynamics AX features.

Book Review: The Baroness

The Baroness by Hannah Rothschild

Some patrons of the arts are rewarded with physical legacies: the family name on the wing of a major gallery, a sculpture park, their portraits in public collections. Others make do with ephemeral acknowledgement, like Baroness Pannonica de Koenigswarter, whose name is written invisibly in the air by a couple of dozen jazz compositions written for her.
The Baroness - aka Nica - was more than a peripheral jazz patron of the 50s passing out cash. She took jazz musicians into her home and supported them, often at great personal cost.
When drug-damaged genius Charlie Parker died in her lounge in 1955 while laughing at a clown on television (he looked aged in his 50s, in reality was just 34), her name was dragged into the public domain.
A wealthy Jewish heiress hanging around with black jazz musicians was rare, and viewed with some suspicion by jazz musicians themselves.
But her loyalty was fierce and unwavering, no more so than to the pianist/composer Thelonious Monk, who she loved platonically and supported through ill-health, drug abuse, erratic behaviour and hospitalisations.
She took the rap for marijuana found in her car (facing three years' jail then deportation) and, for the final decade of his life, Monk - by then damaged, reclusive, often mute and no longer playing - lived in her New Jersey home surrounded by her cats (Monk's son Toot counted 306) while his wife and children would occasionally visit.
Nica paid for his funeral, slipped money to many other musicians and - until her end at 74 in 1988 - was a flamboyant, if faded, nocturnal habitue of jazz clubs.
Throughout her remarkable life the baroness was an exceptional character. She constructed few myths about herself - not that she needed any, she was born a Rothschild so money was never an issue. One of these was that her name, "Pannonica" given by her amateur entomologist father, was a species of exotic butterfly. It was, in fact, a species of common moth. And as an English-born woman attracted to the flame of the dark jazz scene of New York in the 50s, she was a moth bound to get burned.
Yet she seems never to have cared. Jazz and its artists were her calling.
In this candid exploration of her notorious great-aunt's life, Hannah Rothschild doesn't paint her subject as a saintly patron, however, more a mystery to unravel which some in her family prefer to ignore.
For the general reader, that eccentric Rothschild family only three generations on from the Jewish ghetto of Frankfurt is perhaps of as much interest. Nica - who inconveniently died just as the author had got to know her - doesn't fully appear here until halfway through as the writer takes us back to a time when children were rarely seen or heard other than by nurses, tutors or butlers on the great estates with their private museums and zoos.
The Rothschilds could underwrite governments and wars (or withhold the cash if it wasn't in their business interests) and Europe was their playground and corporate territory.
The family's founding-father, Mayer Amschel, enshrined the dynastic injunction that no daughters (nor sons-in-law, nor their heirs) could have any share in running the family firm. So women had their wings clipped as children and were destined for cosseted lives of lunching, planning lavish dinners and travel while the men took charge - or, in the case of the eccentrics, pursued their interests.
Nica was, however, very different. She climbed trees during a childhood of "physical luxury combined with personal neglect" by her parents, attended a Parisian finishing school ("a lesbian seminary"), rode Lipizzaner horses in Austria and had family friend Winston Churchill at her coming-out ball.
She learned to fly and in New York married the dashing Baron Jules de Koenigswarter, whom she'd met while holidaying in France (and had scooted off around Europe with in his private plane, servants and minders in pursuit).
Children followed but Nica barely broke stride. When war came she courageously stayed in her French chateau until three days before the Germans arrived, because Jules was stationed in Africa, then she left her children in New York and enlisted in the Free French Army. She travelled to West and North Africa and was variously a decoder and a driver (rumour has it she also flew Lancaster bombers). After the war she spent time in Norway where her husband was the French ambassador and, always in the background, was the seduction of jazz.
Her globe-trotting inevitably led her to New York where, after again leaving her husband and children, she lived in luxurious hotels, drove her Rolls Royce to jazz clubs, befriended musicians, drank but barely ate (she couldn't cook, had never learned) and became a target for columnists such as Walter Winchell for her associations with black musicians, many of whom were drug addicts and her lovers.
She didn't care about the gossip or the abuse she endured (vehement anti-Semitism and for her unashamed relationships). She cared only about musicians and their music: passionately and with her hand in her purse, or in their hand, when necessary. She was a freedom fighter still.
Hers was a life played out against a backdrop of elegantly managed if obscene wealth, suicide, eccentricity, heroism and personal tragedy. And with a great soundtrack.
After this freewheeling biography, never again will you hear Monk's ballad, Round Midnight - the reverie which flicked a switch in Nica's soul - without thinking of the jazz baroness. Nor of Monk in that final decade, withdrawn from the world and surrounded by hundreds of her free-range felines. Monk hated cats.
