Can I reduce aluminum oxides at 1600˚F?
At the start of this blog series, a question was raised about the ability to remove/dissociate aluminum oxides by heating a vacuum furnace used for aluminum brazing up to about 1600°F (870°C). Look at Fig. 1 once again and notice that the curve for aluminum oxide is at the far right on that chart, along with the oxide curves for titanium and magnesium.
According to Fig. 1, if someone was aluminum brazing in a vacuum furnace at approximately 10-5 torr and they desired to operate one diagonal to the right of the aluminum-oxide curve, they would need to heat their vacuum furnace up to about 2800°F (~1550°C), which is physically impossible. It must be understood that once aluminum oxide forms in a brazing operation, it cannot be removed by any type of thermal process in that furnace.

Guidelines for Furnace Burnout (Clean-up) Cycles
When considering furnace burnout/clean-up cycles, it is important to operate a brazing furnace at a temperature that is at least 100°F (50°C) above the highest processing temperature that is used in that furnace (whether that be for brazing, heat treating or another process) and to hold the furnace at that temperature for a minimum of one hour or longer in order to allow effective volatilization of any materials that may have condensed onto the inside walls during previous heating cycles. Such burnout cycles should also be able to remove/volatilize materials from the hot-zone cage (heating elements, connectors, etc.). Since the hot-zone cage often consists of a number of layers of material, it is important to hold the high-temperature cycle for at least one hour or more to be able to penetrate into those layers.
A furnace burnout cycle is not designed to remove (dissociate) oxides. Instead, it is designed to remove materials – such as oils, lubes, base-metal outgassing products, etc. – from the furnace walls that may have condensed on it over time.

Float SNJ
Float SNJ in Marlton has created the worlds largest floating / sensory deprivation pools. The practice of floating / sensory deprivation has been clinically shown to reduce pain due to muscle tension, swelling, inflammation, and some injury. By using 2,000 pounds of Epsom Salts dissolved in 300 gallons of body temperature water, our floating pools allow you to lay suspended, completely weightless, as if you were floating in space, but warm and snuggly. The weightlessness relieves the pressure from your joints and the Epsom salts reduce swelling and inflammation creating a whole spectrum of positive outcomes from reduction or relief of pain to a decrease in the symptoms of anxiety, stress, and depression.

This example uses both channels of USRP® B210, X300 or X310 to receive an LTE downlink signal. LTE System Toolbox™ is used to perform the cell search procedure and to decode the MIB and SIB1 messages if present.
LTE System Toolbox provides functions and tools to decode LTE waveforms. This example shows how an LTE waveform can be captured with SDR radio hardware such as a USRP®-based radio. The signal can then be analysed and decoded. In this example the captured waveform is searched for the presence of a suitable LTE signal. If found, the MIB and SIB1 messages are decoded.
This example decodes the MIB for a burst of captured frames, and then decodes the control format indicator (CFI) for each subframe, which informs the user equipment (UE) of the size of the control region. The physical downlink control channel (PDCCH) is then decoded. With this information the SIB1 message in the PDSCH is finally decoded.
The example outputs recovered cell wide information including the detected cell identity and checks the SIB1 CRC. The example also plots the signal spectrum, the PDCCH constellation and the magnitude of the channel estimate.
If you have a second SDR platform, a suitable signal can be generated by the companion example Two Antenna LTE SIB1 Transmission using USRP® based Software-Defined Radio (SDR).
This example requires the USRP®-based Radio support package. This can be installed using the Add-On Explorer.
More information about other supported SDR platforms can be found here.
The full example description and source code can be found in the list of examples using USRP® under the name "LTE Cell Search, MIB and SIB1 Recovery with Two Antennas".

Ganga Kalyana Scheme 2018 Karnataka for SC ST OBC Borewell Loan Online Application Form @kmdc.karnataka.gov.in
The scheme was officially launched in the year 2017. The Karnataka Minor Development Corporation Limited has launched the facility. This is the second year of the scheme and beneficiaries are invited by the KMDC to submit their application for the scheme.
- Aim: The scheme aims to provide irrigation facility to the small farmers who are unable to get water resource in their land. The scheme is mainly started for marginal and small farmers who belong to minority, OBC and ST/SC categories.
- Benefits: The scheme would provide proper water supply to the dry lands. Farmers who are small or marginal will get water resources from the government. It will be either bore-well or open well or lift irrigation system that will be provided to the beneficiaries.
- Implementation: The state will provide water resources to the farmers through pipelines or permanent water bodies. If there is not any river, pond or any such permanent water body then an open well will be constructed to provide water supply. These wells will be built in supervision of geologists.
- Financial Assistance: The state government will provide financial assistance to the farmers to build the Borewell and open wells in suitable land. This financial Help will be provided by the KDMC.
- Budget: To make this scheme implement, mainly the construction cost of wells and irrigation system, the state government of Karnataka has set a budget of Rs. 1.5 Lac per beneficiary.
Eligibility – For Lift Irrigation Facility
- Citizens: The beneficiaries have to be the permanent citizen of Karnataka. Any migrant or non-residential will not be able to get the benefits of the scheme.
- Categories: The farmers must belong to the Scheduled Caste, Scheduled Tribe, Other Backward Classes or Minority category. Apart from that the farmers must be small or marginal farmers to get the benefits from the scheme.
- Annual Income: Annual income of the family of beneficiaries will be Rs. 22, 000/ per year. Anyone earning more than that in a year would not be eligible for the scheme.
- Land Holding: Farmers, who have less than 5 acres of land holding with 7 minority family members are associated with the land, will get lift irrigation facility under this Ganga Kalyana Scheme in Karnataka.
For Bore-well Facility
- The eligibility criteria for the individual bore-well or open well will be same as the Lift Irrigation facility. Farmers who own minimum 2 acres and maximum 5 acres of land and no nearby permanent water supply will get one well from the state.
- In case of construction of borewells, KDMC will supervise the construction and maintenance of the wells. After 5 years, consumer cooperatives will supervise the work of such wells with pumps and other types of wells under the scheme.
Online Application Form Download
The forms for the scheme are available online. The beneficiaries can go to the official website of the scheme _URL_ to get the forms. Or they can directly click on the link _URL_ to download the form and the format. For more Details click here _URL_
All the beneficiaries are required to submit the filled up forms to the District Magistrate of their respective districts. After verification by the District Magistrate, the forms will be transferred to the Taluk Committee. The Taluk Committees are led by the MLAs of the concerned areas. Further the selected applications will be transferred to the concerning department for further process.
The scheme will help the farmers to get proper and non-stop water resources in their lands. Hence they are losing their agricultural produce. This scheme will not only help them to grow their production but also will be encouraging for agricultural promotion in the state.

Quote1.png You have a very strange sense of humor, Dr. Palmer. Quote2.png
Batman/Superman #10 is an issue of the series Batman/Superman (Volume 1) with a cover date of July, 2014. It was published on May 7, 2014.
Synopsis for "Enter the Microverse"
In the Ant Farm, Father Time and Dr. Belroy determine that their intervention is not required in Green Arrow's battle with the Outsiders in Prague. However, metahumans appear to be clustering up in Canada, requiring some attention. Suddenly, an alarm sounds, and they realize that their microscopic base has been grabbed out of the air by Superman, who demands to speak with Dr. Ray Palmer immediately.
Within two hours, Superman has Dr. Palmer with him at the Fortress of Solitude. Superman explains that ever since repairing a Chinese space station, Batman has been unresponsive. Ray is confused, because he's a physicist, not a medical doctor. Superman reminds that Ray's work centres around matter reduction and shrink technology - so who better to investigate what infected Batman, when he is affected by something so unique? Handing Ray a small blood sample from Batman, he allows the doctor to inspect it on a microscopic level, revealing that among the blood cells, there floats what appears to be a microscopic dead super-hero. In fact, Superman had discovered an entire microscopic city built up in a blood vessel in Batman's brain. That city - or whoever built it - is killing Batman, and Superman feels that he and Ray need to get into that blood vessel and remove the danger. Ray admits that he can help.
Soon, Ray has dressed himself and Superman with special containment suits equipped with personal reduction matrices - or shrink belts. He explains that he has added a failsafe for Superman's, so that if anything goes wrong, he'll immediately be ejected and returned to his normal size. Arranging to arrive in Batman's brain to scale with the city, which is located in the part of the brain that controls sleep - explaining the coma Batman has fallen into.
Inside Batman's brain, Ray determines that the jungle surrounding the city is certainly alien in nature, with an artificial structure underneath its roots extending all the way to the centre of the city. In fact, he believes that the city is actually some kind of microscopic spacecraft in its totality. Suddenly two of the city's inhabitants rush over to them, speaking in an alien language, but Ray's S.H.A.D.E.-issued Universal Translator provides them some insight. The woman begs for help, explaining that something that her people had been transporting to their homeworld had got free and killed the captain of the vessel, making all the inhabitants into slaves. Ray suggests that the body they found in Batman's blood was their Captain Boltstar.
Unexpectedly, two strong looking aliens attack Superman, and the woman identifies them as Dr. Smashammer and Titan Super Gladiator - greatest criminals of the empire (Ray must admit that the translator isn't perfect, with names like these). While fending off Titan Super Gladiator, Superman's shrink-belt gets yanked off, and before he can be stopped, the brute has grown several times his size - ejecting suddenly into the Fortress of Solitude, and finding himself standing next to Batman. Assuming that Batman must be the king of this world, he resolves to kill him and win his kingdom.
Meanwhile, Superman manages to subdue Dr. Smashammer, allowing Ray the opportunity to use his P.R.I.M.P - a portable reduction inducing matrix pod. With it, he shrinks down the city and its inhabitants within an empty Ant Farm, so he and Superman can get out of Batman's brain with it.
In the Fortress, Batman wakes suddenly, and is forced to defend himself almost immediately upon doing so. Unable to understand his attacker's alien language, Batman assumes that the creature his hostile and flings razor-sharp batarangs at it.
Batman's physical altercation has seemingly earth-moving effects in his brain as Superman and Ray wait for the city to finish shrinking. Ray explains that Batman's blood pressure is increasing, and it might even tear the city apart before they can do a thing to save it. Fortunately, Bruce rallies, allowing the shrinkage to complete. Finally, Ray and Superman can escape the brain - using just the remaining power in Ray's shrink-belt, in Superman's belt's absence.
As Superman and Ray are expelled through Batman's nose, Bruce reacts with total confusion. Upon returning to their normal size, Superman smirks at the sight of the unconscious alien on the floor of the Fortress, realizing that he should have known Batman wouldn't need saving. After hearing their otherworldly explanation for Titan Super Gladiator's attack and their being in his head, Batman simply grunts that he needs an aspirin and takes his leave.
Later, Ray decides that he should take the microscopic city-ship back to S.H.A.D.E. with him, promising Batman that he will take full responsibility for them, knowing that S.H.A.D.E. has not earned the heroes' trust. Before going on his way, Ray suggests that he has been thinking of a code name for himself: The Atom. Grimly, Batman reminds Superman that they have already met an Atom from another Earth, and expresses suspicions about all the technology that S.H.A.D.E. seems to have.
Meanwhile, from the Ant Farm, Father Time and Dr. Belroy gleefully congratulate themselves on having surreptitiously planted trackers and sensors on both Superman and Batman without either their or Dr. Palmer's knowledge.

parser/parser.cpp Parser class was also derived from wxEvtHandler, can start batch parse... this class has member variables like :cbThreadPool m_Pool(which will create a thread from thread pool for each file need passed);TokenTree* m_pTokens(contains all the Token database);
parser/token.cpp definition of the "Token" class, and TokenTree(which means the Token dababase)
parser/searchtree.cpp implement the patricia search tree using by TokenTree
Header files no description needed
Structure of CodeCompletion plugin
Code completion plugin Structure
The above image show the main structure of our CodeCompletion plugins. The main class are:
 - CodeCompletion: this is the class for main plugin), it handle event sent from the C::B core. Toolbar handling was done in this class.
 - NativeParser: as a main member variable of the CodeCompletion class, this class is like the Parser manager class, it create/delete Parser instances when a project load/closed.
 - Parser: this class is mainly for handling Tokens. Parser class hold a TokenTree which record all the Tokens. Parser class also hold a thread pool, it can either run the parsing task in the pool(this means the parsing task will be done in a separate thread), or directly by a function call.
 - Parserthread: The class derived from the worker thread(cbThreadedTask class), it member function DoParse() is the function for parsing.
Besides that, when trying to show the suggestion list(auto completion list, or code completion list), the NativeParser need to analyze the current the current statement structure, and query the symbol(token) information from the Tokentree, this is mostly done in ResolveExpression() member function.
Some important note: when all Parserthread instances finish parsing job in the pool, the thread pool will send an event to its parent(in this case, it is the Parser class), so the Parser know that the parsing is done, or the Parser can assign another parsing jobs to the thread pool.
Low level parser(Lexical analysis, Tokenize)
for a simple c++ program like below
int main()
 return 0;
After tokenizing, it should give these 15 tokens
1 = string "int"
2 = string "main"
3 = opening parenthesis
4 = closing parenthesis
5 = opening brace
6 = string "std"
7 = namespace operator
8 = string "cout"
9 = << operator
10 = string ""hello world""
11 = string "endl"
12 = semicolon
13 = string "return"
14 = number 0
15 = closing brace
Tokenizer class
preparing the big string
Get or Peek a token
 //Get the current token string started from m_TokenIndex,
 //After that, increase the m_Tokenindex
 wxString GetToken();
 wxString PeekToken();
Cb token cache.png
Nested Value of braces
 if (CurrentChar() == '{')
 else if (CurrentChar() == '}')
SkipUnwanted tokens
a = b + c;
// assignment statement in template arguments
template
class abc {
 T m_a;
// assignment statement in function arguments
void foo( int arg1 = 60 )
 bla bla;
Return a correct token, Macro replacement
Cc std replacement.png
wxString Tokenizer::MacroReplace(const wxString str)
 wxStringHashMap::const_iterator it = s_Replacements.find(str);
 if (it!= s_Replacements.end())
 // match one!
 wxString key = it->first;
 wxString value = it->second;

 return value.Remove(0,1);
 else if (value[0] == '-')
 unsigned int lenKey = key.Len();
 value = value.Remove(0,1);
 unsigned int lenValue = value.Len();
 for (unsigned int i=1; i<=lenKey; i++)
 if (i < lenValue)
 m_Buffer[m_TokenIndex-i] = value[lenValue-i];
 m_Buffer[m_TokenIndex-i] ='';
 int firstSpace = value.First(' ');
 // adjust m_TokenIndex
 m_TokenIndex = m_TokenIndex - lenValue + firstSpace;
 return value.Mid(0,firstSpace);
 return value;
 return str;
Code completion build target option in code::blocks
replacement rules
directly replacement AAAAA -> BBBBB
You can define a rule: AAAAA -> BBBBB
Which means, if the tokenizer meet a string "AAAAA", then it will returned a string "BBBBB"
For example, when
 /// See bits/stl_deque.h's _Deque_base for an explanation.
 template
 struct _Vector_base
 typedef typename _Alloc::template rebind<_Tp>::other _Tp_alloc_type;
We should replace the string "_GLIBCXX_BEGIN_NESTED_NAMESPACE(std, _GLIBCXX_STD_D)" to "namespace std {", here, we introduce two replacement rules:
In this rule, we firstly replace the "_GLIBCXX_BEGIN_NESTED_NAMESPACE" with the "namespace", then, we reserve the "std", and change the closing parenthesis to an opening brace. (See the image above), also, every token string "_GLIBCXX_END_NESTED_NAMESPACE" will be replaced by "}". CCreplacement rule.png
So, the code becomes to like below:
namespace std {
 /// See bits/stl_deque.h's _Deque_base for an explanation.
 template
 struct _Vector_base
For example, when
We should replace the string "_GLIBCXX_BEGIN_NAMESPACE_TR1" to "namespace tr1 {", here, we introduce two replacement rules:
In this rule, we firstly replace the "_GLIBCXX_BEGIN_NAMESPACE_TR1" with the "namespace", then, add aditional string "tr1 {"
So, the code becomes:
namespace tr1 {
AAAAA -> *
In this case, we call it a "strip the next "(" and ")" rule. for example:
The rule syntax is:
For example, In the source code below:
CVAPI(void) cvFxxxx();
CVAPI(cvMat *) cvFyyy();
will become to (if I add a replacement rule CVAPI -> *)
void cvFxxxx();
cvMat * cvFyyy();
High level parser(Syntax Analysis)
This is the main flow of a parser.

Handling class declaration
class AAA{
 int m_a;
 int m_b;
} ;
What about these statements
class AAA{
 int m_a;
 int m_b;
} x,y,z;
Handling typedef statement
Sometimes, you can see these code blocks:
typedef class AAA{
 int m_a;
 int m_b;
Next, it meets a keyword "class", which also indicate it is a class declaration. So, the HandleClass function will do the task. A Token of "class AAA" will be added to the TokenTree. Wait a minute, how can we deal with "BBB" and "CCC", this is not the same case as previous code, we can't regard "BBB","CCC" as variables. In this case, another function "ReadClsName()" will be called. For simplicity of TokenTree, we just regard "BBB

Location: Gunter Annex, Maxwell AFB, Montgomery, AL
Client: USACE, Omaha District
The Gunter Annex surface drainage system is designated as site SD-001 under the Installation Restoration Program (IRP) and is located immediately adjacent to Gunter Annex. The property is currently owned by the Alabama Department of Corrections (ADOC). Drainage associated with Gunter SD-001 initiates from within the boundaries of Gunter Annex and flows from three pipes located just east of the site into an ecologically sensitive, area known as Three Mile Branch Creek. It is believed that pesticide runoff in surface water from Gunter Annex contributed to the drainage ditch impacts. Chlordane was detected in sediment samples, from within the ditch, at concentrations up to 13 times the ecological screening levels. Bhate developed an innovative in-situ remedial approach using sodium persulfate to oxidize the contaminants. Our approach resulted in a cost avoidance of $1.2M for the Air Force – without impact to the installation mission or the ecologically sensitive areas adjacent to SD-001.

The biggest hurdle I have had to overcome in order to use Tsung for load-testing Postgresql servers has been a conceptual mismatch between Tsung and what I wanted to do. Tsung's model probably originates in the load-testing of web servers: everything is described in terms of user arrival rate, hits, pages, transactions, thinktimes. Database usage may not be readily described in these terms.
Before going any further, I should probably make clear I didn't need Tsung to do performance testing. Performance testing may be easily done by throwing a specific set of SQL queries to the database server (in controlled conditions) and checking/timing the results (this could be a separate tutorial :-). Tsung gives you the tools to model proper user interaction and real-life usage and I have been trying to determine a server's load capacity.
In other words, how many times our typical or target load could a particular server/set-up handle?
And this load had to be expressed in a Tsung-compatible xml file describing mainly:
 - alternative user sessions (with associated probabilities)
 - user arrival rate
Here's a quick reminder of what Tsung transactions mean:
Different parts of a session may be grouped into transactions (Tsung-speak — nothing to do with your normal database transactions) for statistical monitoring of SQL groups. Transactions are characterised by their name, and names may be shared across sessions. This way, there are tremendous reporting possibilities, as all sessions may have a "connection" transaction offering global connection statistics, while transactions with unique names produce statistics on a specific use-case basis (e.g. complex data search, typical page load etc.).
For simplicity, I have opted to include only two "transactions" in each alternative user "session" (use-case):
 - a connection transaction (identified as "connection" in all "sessions")
 - a SQL block transaction (with a unique, "session"-specific name)
Know your (target) usage
Here comes the obvious but imporant bit: you need to know your real-life or your target usage to proceed! Expressing your (target) usage into Tsung values is the only thing that binds your experiment to real-life and allows some conclusions to be drawn from the tests.
The defined "sessions", should, of course, reflect your usage profile. This boils down to including a representative variety of use-cases, with the right probability factor assigned to each case.
But you also need to express the number of new "sessions" per second Tsung initiates against your system, i.e. the Tsung user arrival rate.
Adapting the scenario file
This is a quick summary of what you should edit in your Tsung scenario file to specify the desired load:
 - allocate different probabilities to your alternative "sessions" (do they add up to 100?)
 - make sure you wrap the important bits of each session into unique "transactions"
 - define appropriate user arrival rates in your "load phases"
Load phases are defined in this section of the Tsung scenario file:
 <load>
 <arrivalphase phase="1" duration="1800" unit="second">
 <users interarrival="10" unit="second"></users>
 </arrivalphase>
 <arrivalphase phase="2" duration="1800" unit="second">
 <users interarrival="6" unit="second"></users>
 </arrivalphase>
 ... and so on...
 </load>
Analyzing the results
Assuming have managed to run your tests, now comes the tricky part of interpreting your results. The Tsung helper perl script generates a multitude of graphs, but here's a quick shortcut. The files which have been most useful to me are the following:
 - report.html
 - images/graphes-Transactions-max_sample.png
 - images/graphes-Transactions-mean.png
 - images/graphes-Users-simultaneous.png
When looking at these graphs, the two most important things to remember are the length (in seconds) of each load phase and what each phase represents. For example, the following graph (manually colored for convenience), may be divided into four sections, each representing a particular load phase (each phase lasted 1800 seconds, i.e. half an hour). This graph basically tells us things start to fall apart at 8x our target load.
simultaneous DB users
The reason the interpretation of this graph is easy is that we are not using any loops in each user "session". Each Tsung "user" simply connects, sends a particular SQL block to the server, receives some results and exits. The user arrival rate stays constant throughout a particular load phase. Statistically speaking, if the server is responding properly, the number of new users in the system is always matched by the number of users exiting. Therefore, you only get simultaneous Tsung users if things start going wrong, when the server's response times are increasing. And when you see the green and red lines splitting, things have gotten out of hand: Tsung is introducing new users which are not even able to connect!
We should always, of course, check, if the server's performance was acceptable while it was "coping" with our load. In addition to the numbers in report.html, you could get the big picture by simply looking at images/graphes-Transactions-max_sample.png. The horizontal line for each "session" corresponds to the longest response time ever recorded for a particular use-case.
max-elapsed-time-per-transaction
Armed with this knowledge, you may start experimenting further. Does your server recover from brief spikes of activity (e.g. long 4x phase, brief 16x phase, 4x phase etc.)? What effect do particular server configuration changes have on load capacity? And so on… This could easily turn into a full-time job 🙂

This article explores the potential role of low-wage service sector unions in engaging in equity-minded school reform. The members of many such unions are parents of children attending poorly resourced public schools. In seeking to address the interests of their members, labor unions can draw upon resources, organizing strategies, and political relationships to contribute to grassroots campaigns for educational equity. Data gathered in Los Angeles from labor and civic leaders, as well as janitors belonging to the Service Employees International Union Local 1877, reveal possibilities for low-wage service sector unions to build alliances around educational reform issues and support their members' individual capacities to advocate for their own children in schools. At the same time, low-wage service sector unions face challenges to participating in school reform efforts, including prioritizing education issues among other competing interests and identifying common ground with teachers' unions.

'Les Lavandieres'
By Sir Samuel Henry William Llewellyn PRA (1858–1941)
Oil on canvas, signed and dated 1887, this is a large scale, rare to the market example of Llewellyn's mature work in the plein air manner, and is provenanced to the descendants of the original purchaser.
Private Collection, UK; thence by descent
Sir (Samuel Henry) William Llewellyn PRA (1858–1941) was a noted and important English painter of the late 19th and early 20th centuries, and served as President of the Royal Academy from 1928 to 1938, and was awarded the Albert Medal (Royal Society of Arts) in 1933.
Llewellyn has 67 paintings in British national collections, including a portrait of industrialist and philanthropist Sir Alexander Grant held by the University of Edinburgh.
A student of Sir Edward Poynter, (whom he later succeeded as the President of the Royal Academy), and later, in France, under the direction of Jules Joseph Lefebvre, (member of the Legion d'honneur, and a leading light in the Academie des Beaux-Arts, and painting professor at the Academie Julian); Sir Samuel Llewellyn worked in the broad brush plein air manner in the French countryside, especially in Brittany, with the women (Les Lavandieres) depicted being shown in regional Breton costumes.
Returning to England, he worked with the Newlyn School artists colony; his early exhibited works, around the date of our painting include prosaic life views of the locals of St Ives and Newlyn. He exhibited at the Royal Academy from 1884 onwards in a more conservative manner from the early 1900's as a portraitist, his subjects including Queen Mary (1912), a gift from Queen Mary to King George V, now in the Royal Collection Trust.
Exhibitor at the New English Arts Club, the Grosvenor Gallery and the Royal Society of British Artists, he was appointed a trustee of the National Gallery from _PHONE_.

* Beauty queen's amputation is rare complication of septicemia
* Update: Mariana Bridi da Costa died on Jan. 24.
A Brazilian beauty queen underwent amputation of her hands and feet earlier this week, a rare and tragic consequence of a common infection.
The woman, Mariana Bridi da Costa, 20, was diagnosed with a bacterial infection that progressed to septicemia. Septicemia, which is also called bacteremia or sepsis, occurs when bacteria gets into the bloodstream. The illness is always serious and can become life-threatening very quickly. Septicemia can arise from any infection in the body, such as in the lungs, abdomen and urinary tract. News reports describe Bridi's case as a urinary tract infection caused by the bacteria Pseudomonas aeruginosa. This type of bacteria is usually contracted in the hospital.
Once bacteria enters the bloodstream, infection can wreak havoc. The patient often appears to have a severe case of the flu, according to information from the National Institutes of Health. A high fever, chills, rapid heart rate and rapid breathing are common. The patient can go into shock if not treated quickly, and the death rate can be as high as 50% depending on the type of bacteria. Patients are treated with antibiotics, fluids, blood pressure medication and sometimes blood products to prevent clotting.
Amputations of limbs are rare and most often occur in children and young people with septicemia because the infection causes clotting that then leads to tissue death.
Relatives of Bridi, who was a finalist to represent Brazil in the Miss World contest, emphasize that doctors are trying to save her life. A study published in September in the journal Pediatrics urges doctors not to withdraw life support in such severe cases of septicemia. The researchers studied children who underwent amputations because of meningococcal septicemia three to five years after their surgeries and found they were coping well and "had a good quality of life."

Creating a Session and Running It
Once we are done describing the computation graph, we are ready to run the compu‐
tations that it represents. For this to happen, we need to create and run a session. We
do this by adding the following code:
sess = tf.Session()
outs = sess.run(f)
sess.close()
print("outs = {}".format(outs))
Out:
outs = 5
First, we launch the graph in a tf.Session. A Session object is the part of the Ten‐
sorFlow API that communicates between Python objects and data on our end, and
the actual computational system where memory is allocated for the objects we define,
intermediate variables are stored, and finally results are fetched for us.
sess = tf.Session()
26 | Chapter 3: Understanding TensorFlow Basics
The execution itself is then done with the .run() method of the Session
object. When called, this method completes one set of computations in our graph in
the following manner: it starts at the requested output(s) and then works backward,
computing nodes that must be executed according to the set of dependencies. There‐
fore, the part of the graph that will be computed depends on our output query.
In our example, we requested that node f be computed and got its value, 5, as output:
outs = sess.run(f)
When our computation task is completed, it is good practice to close the session
using the sess.close() command, making sure the resources used by our session are
freed up. This is an important practice to maintain even though we are not obligated
to do so for things to work:
sess.close()
Example 3-1. Try it yourself! Figure 3-3 shows another two graph examples. See if you
can produce these graphs yourself.
Figure 3-3. Can you create graphs A and B? (To produce the sine function, use tf.sin(x)).
Constructing and Managing Our Graph
As mentioned, as soon as we import TensorFlow, a default graph is automatically cre‐
ated for us. We can create additional graphs and control their association with some
given operations. tf.Graph() creates a new graph, represented as a TensorFlow
object. In this example we create another graph and assign it to the variable g:
Graphs, Sessions, and Fetches | 27
import tensorflow as tf
print(tf.get_default_graph())
g = tf.Graph()
print(g)
Out:
<tensorflow.python.framework.ops.Graph object at 0x7fd88c3c07d0>
<tensorflow.python.framework.ops.Graph object at 0x7fd88c3c03d0>
At this point we have two graphs: the default graph and the empty graph in g. Both
are revealed as TensorFlow objects when printed. Since g hasnt been assigned as the
default graph, any operation we create will not be associated with it, but rather with
the default one.
We can check which graph is currently set as the default by using
tf.get_default_graph(). Also, for a given node, we can view the graph its associ‐
ated with by using the <node>.graph attribute:
g = tf.Graph()
a = tf.constant(5)
print(a.graph is g)
print(a.graph is tf.get_default_graph())
Out:
False
True
In this code example we see that the operation we've created is associated with the
default graph and not with the graph in g.
To make sure our constructed nodes are associated with the right graph we can con‐
struct them using a very useful Python construct: the with statement.
The with statement
The with statement is used to wrap the execution of a block with
methods defined by a context manager—an object that has the spe‐
cial method functions .__enter__() to set up a block of code
and .__exit__() to exit the block.
In laymans terms, it's very convenient in many cases to execute
some code that requires "setting up" of some kind (like opening a
file, SQL table, etc.) and then always "tearing it down" at the end,
regardless of whether the code ran well or raised any kind of excep‐
tion. In our case we use with to set up a graph and make sure every
piece of code will be performed in the context of that graph.
28 | Chapter 3: Understanding TensorFlow Basics
We use the with statement together with the as_default() command, which returns
a context manager that makes this graph the default one. This comes in handy when
working with multiple graphs:
g1 = tf.get_default_graph()
g2 = tf.Graph()
print(g1 is tf.get_default_graph())
with g2.as_default():
print(g1 is tf.get_default_graph())
print(g1 is tf.get_default_graph())
Out:
True
False
True
The with statement can also be used to start a session without having to explicitly
close it. This convenient trick will be used in the following examples.
Fetches
In our initial graph example, we request one specific node (node f) by passing the
variable it was assigned to as an argument to the sess.run() method. This argument
is called fetches, corresponding to the elements of the graph we wish to com‐
pute. We can also ask sess.run() for multiple nodes' outputs simply by inputting a
list of requested nodes:
with tf.Session() as sess:
fetches = [a,b,c,d,e,f]
outs = sess.run(fetches)
print("outs = {}".format(outs))
print(type(outs[0]))
Out:
outs = [5, 2, 3, 10, 5, 5]
<type 'numpy.int32'>
We get back a list containing the outputs of the nodes according to how they were
ordered in the input list. The data in each item of the list is of type NumPy.
Graphs, Sessions, and Fetches | 29
NumPy
NumPy is a popular and useful Python package for numerical com‐
puting that offers many functionalities related to working with
arrays. We assume some basic familiarity with this package, and it
will not be covered in this book. TensorFlow and NumPy are
tightly coupled—for example, the output returned by sess.run()
is a NumPy array. In addition, many of TensorFlow's operations
share the same syntax as functions in NumPy. To learn more about
NumPy, we refer the reader to Eli Bresserts book SciPy and NumPy
(O'Reilly).
We mentioned that TensorFlow computes only the essential nodes according to the
set of dependencies. This is also manifested in our example: when we ask for the out‐
put of node d, only the outputs of nodes a and b are computed. Another example is
shown in Figure 3-1(B). This is a great advantage of TensorFlow—it doesnt matter
how big and complicated our graph is as a whole, since we can run just a small por‐
tion of it as needed.
Automatically closing the session
Opening a session using the with clause will ensure the session is
automatically closed once all computations are done.
Flowing Tensors
In this section we will get a better understanding of how nodes and edges are actually
represented in TensorFlow, and how we can control their characteristics. To demon‐
strate how they work, we will focus on source operations, which are used to initialize
values.
Nodes Are Operations, Edges Are Tensor Objects
When we construct a node in the graph, like we did with tf.add(), we are actually
creating an operation instance. These operations do not produce actual values until
the graph is executed, but rather reference their to-be-computed result as a handle
that can be passed on—ow—to another node. These handles, which we can think of
as the edges in our graph, are referred to as Tensor objects, and this is where the
name TensorFlow originates from.
TensorFlow is designed such that first a skeleton graph is created with all of its com‐
ponents. At this point no actual data flows in it and no computations take place. It is
only upon execution, when we run the session, that data enters the graph and compu‐
30 | Chapter 3: Understanding TensorFlow Basics
tations occur (as illustrated in Figure 3-4). This way, computations can be much more
efficient, taking the entire graph structure into consideration.

is run, actual data "ows" through the graph.

In a deregulated electricity industry, new concerns have emerged regarding the quality of the power supply as companies tend to focus on their own objectives and interests. One main concern regarding power-supply quality is voltage fluctuation. Voltage fluctuations are defined as repetitive or random variations in the magnitude of the supply voltage. This paper addresses a method for monitoring the voltage flicker using state estimation (FSE). A test system is used to characterize the new algorithm in which parameter inaccuracies have been considered. The new algorithm can be used by operators as well as distribution companies to monitor the flicker severity throughout the network.

Choosing good paint brushes for your art is an important step in gathering your art materials. Here are some guidelines to consider when making your purchases.
 1. 1
 Familiarize yourself with the brushes. Typically, an artist will have many different types of brushes for different techniques and painting methods:
 2. 2
 Familiarize yourself with different hair-types. There are different materials used for brushes:
 - Bristle - usually the cheapest - made from pig hairs. This is a standard brush that you would find often in artists' collections.
 - Synthetic - these can be cheap or expensive and they have a different feel than natural hair brushes.
 - Sable - usually the most expensive - made from various other fine-haired animals, such as sables, weasels, and other rodents.
 3. 3
 Choose a brush that feels good and is well-built:
 4. 4
 Look for sales at art supply stores. If you are a student, be sure to go to stores that honor student discounts. Paying full price for art supplies is rarely wise, as artists are not known for being wealthy.
 5. 5
 Collect together one of each of these brushes and additional sizes of the main workhorse brushes - the flat and the filbert. You may also want a very wide flat brush (like a 2" wide house painting brush) for covering very large areas initially.
 6. 6
 Learn about the different ways each brush can be held and the different ways of making strokes. This knowledge will also come with experimentation, which is clearly the best way to learn. What you are trying to accomplish will generally decide which brush is best for which job.

This video covers the different types of brushes and uses.
 - Brushes can get quite expensive, so take care of them: don't leave them sitting in water, don't get paint up into the ferrule (the metal part), and wash and dry your brushes thoroughly right after use.
 - Go with what works for you. If a cheaper brush does a better job and feels right, use that instead. You don't always have to have the most expensive items.

First remember that for many readers "Colonel" and "Sergeant" are just as alien as "Oberst" and "Feldwebel". A civilian who doesn't know rank may well assume both are just some kind of soldier. To truly understand the rank dynamic, show how the two interact, or how one person reacts when he is preparing to meet (or surprised by) someone of another rank.
How do they think about each other? Sergeants worry about whether the colonel who is coming is a good or bad officer; Colonels don't have time to worry about the sergeant they are about to meet. Lieutenants worry about themselves, and occasionally about the next officer up the chain, while Captains worry about their lieutenants.
How do they act around each other? Use the right verb to convey the tone and intent. A lieutenant may question a captain or correct a sergeant but may feel the need to instruct an airman. A Major, on the other hand, will not explain much of anything - he will order or direct and then probably leave, unless he's recently promoted and still falling back into the habits of a Captain.
Speaking is pretty simple because you have the honorifics and shortcuts that make military speech so efficient. But even the difference between "yessir" and "yes, sir!" lets your reader understand the speaker a little more.
Show the work that they have to do. A sergeant's job is greasy, muddy, back-breaking, or tedious. A lieutenant's job might be more accurately described as titchy, stressful, or never-ending. A colonel's job might not seem like work at all until you realize he's doing it from the time he wakes up until the time he sleeps, for months on end. Describe the tasks they are working on when the narrative interrupts them.
If you put enough clues about their clothing, work habits, and relative moods, the reader will understand the people and not just their relative ranks.

Tea Extracts Repair Radiotherapy Skin Damage
Posted: December 8, 2006
Findings from a new study confirm that tea extracts applied to the skin promote the repair of damage from radiotherapy, and shed light on the mechanisms involved in the injury. The beneficial effects of the extracts are mostly from their ability to attenuate the body signals that trigger inflammation.
Radiotherapy interruption because of toxic effects to the skin may compromise the outcome of cancer treatment, lead author Dr. Frank Pajonk, from the David Geffen School of Medicine at UCLA, told Reuters Health. "So, it is important to have an effective treatment for this problem."
According to Pajonk, "tea extracts have been used as a folk remedy for sunburns, which led to their use as a treatment for radiation-induced skin toxicity. They have proven quite successful in this regard, but there were no scientific data" to clarify their effects.
In a study reported in the journal BMC Medicine, the researchers analyzed the effects of green or black tea extracts given to 60 patients with skin damage related to radiotherapy for head and neck cancers and cancer in the pelvic region.
Treatment with the tea extracts enhanced skin repair, the report indicates. For radiation damage in the head and neck region, the green and black tea extracts were comparable in promoting repair, whereas in the pelvic region, green tea extract was superior, Pajonk said.

Alarm Clock FAQ
Last Updated January 2020

Q. What is a dual alarm clock?
A.
A dual alarm clock is a single clock that allows users to set two separate alarm times. This is an invaluable feature for bed partners who get up at different times, as it eliminates the need to reset the alarm – an action that's easily forgotten in the early hours of the morning.
Q. How do some alarm clocks automatically set and update the time?
A.
These radio-controlled clocks receive a signal from a time-accurate atomic clock and synchronize themselves accordingly. In the U.S., the signals come from the National Institute of Standards and Technology's radio station.
Q. Why not just use the alarm clock app on my smartphone?
A.
Aside from being able to quickly and easily tell the time throughout the night, studies show that using an alarm clock may improve sleep patterns. Without the temptation to check messages or play one last round of a favorite game every time you set your phone alarm, healthy and consistent sleep habits are easier to establish.
Related: See our review of the best clock radios here.
If you're hard of hearing or simply prefer waking up without noise, opt for an alarm clock with an independent vibration feature.

The Stacks project
Remark 86.21.2. In [Definition 1.7, ArtinII] a formal modification is defined as a proper morphism $f : X \to Y$ of locally Noetherian formal algebraic spaces satisfying the following three conditions1
 1. the Cramer and Jacobian ideal of $f$ each contain an ideal of definition of $X$,
 2. the ideal defining the diagonal map $\Delta : X \to X \times _ Y X$ is annihilated by an ideal of definition of $X \times _ Y X$, and
 3. any adic morphism $\text{Spf}(R) \to Y$ lifts to $\text{Spf}(R) \to X$ whenever $R$ is a complete discrete valuation ring.
Let us compare these to our list of conditions above.
Ad (i). Property (i) agrees with our condition that $f$ be a rig-étale morphism: this follows from Lemma 86.8.2 part (7).
Ad (ii). Assume $f$ is rig-étale. Then $\Delta _ f : X \to X \times _ Y X$ is rig-étale as a morphism of locally Noetherian formal algebraic spaces which are rig-étale over $X$ (via $\text{id}_ X$ for the first one and via $\text{pr}_1$ for the second one). See Lemmas 86.17.5 and 86.17.7. Hence property (ii) agrees with our condition that $\Delta _ f$ be rig-surjective by Lemma 86.18.12.
Ad (iii). Property (iii) does not quite agree with our notion of a rig-surjective morphism, as Artin requires all adic morphisms $\text{Spf}(R) \to Y$ to lift to morphisms into $X$ whereas our notion of rig-surjective only asserts the existence of a lift after replacing $R$ by an extension. However, since we already have that $\Delta _ f$ is rig-étale and rig-surjective by (i) and (ii), these conditions are equivalent by Lemma 86.19.3.
[1] We will not completely translate these conditions into the language developed in the Stacks project. We hope nonetheless the discussion here will be useful to the reader.

Personal control: an important psychological resource in difficult times
A new study by Nguyen et al. (2020) looks at the extent to which a sense of personal control can protect people's well-being in difficult times.
Personal control can come under pressure in difficult times
In times when many people are struggling, such as when economic inequality is on the rise, people's sense of personal control can come under pressure. Personal control is the feeling that there is a clear relationship between your behavior and what is happening in your daily life. When this sense of personal control is under pressure, people can experience arbitrariness and chaos that can greatly diminish their well-being. When personal control is threatened, people can resort to external or internal resources.
How do we avoid a sense of randomness and chaos?
Two theories (the compensatory control model and the system justification theory, respectively) postulate that there are two known external resources that people can resort to as compensation for a lack of personal control, namely God and government. By relying on these systems, people would hope to escape a sense of arbitrariness and chaos. Various psychological theories, such as the self-determination theory (SDT), state that people can derive a sense of personal control from internal resources and that this is related to well-being. In particular, SDT is about the fulfillment of the basic needs for autonomy and competence.
Personal control vs. faith in God and trust in government
Nguygen et al. conducted a study in which they tried to answer two questions. The first question was, is there a unique role for personal control over and beyond faith in God and trust in government? The researchers expected this to be the case. The second question was, is personal control only related to well-being in rich, developed countries (which generally have a more individualistic culture)? The researchers expected that personal control would be more closely related in countries with lower GDP and higher economic inequality.
They examined data from nearly half a million people from 104 countries over the period from 1981 to 2014. The variables they included in their research were religious belief, trust in government, personal control, happiness, health and satisfaction with one's own life, some control variables, GDP and the Gini coefficient. The table below lists some of the important results they found.
Personal control strongest predictor of well-being
This table shows that religious belief, trust in government, and personal control all predicted happiness and satisfaction with life. The general health of the citizens was also predicted by trust in government and personal control, but not by religious belief. Religious belief only predicted greater health and buffered the negative effect of income inequality on health in the prosperous economies, but showed negative correlations with health in poor economies. Furthermore, it is noticeable that personal control provided significant and independent predictive value above and beyond belief and trust in government and was consistently the strongest predictor of all three aspects of well-being.
The relationships between personal control and trust in government with well-being outcomes were consistently positive at different levels of countries' GDP and Gini. Personal control also fulfilled a compensatory function by buffering the negative effect of income inequality in prosperous economies.
Psychological resource available to everyone in difficult times
This research shows that the freedom to make decisions and control your life is an important psychological resource, and something that people of any walk of life can rely on, even in difficult times.


What is Normal Oil Temperature
Author:
Published:
Updated:
The normal oil temperature for a car is typically between 195 and 220 degrees Fahrenheit. If the oil temperature gets too high, it can start to break down and cause engine damage.
Normal oil temperature varies depending on the make and model of your car. However, most mechanics agree that normal operating temperature for most cars is between 195 and 220 degrees Fahrenheit. If your car's oil temperature exceeds this range, it is considered overheated and you should take steps to cool it down.
What Should My Oil Temp Gauge Read?
Most people believe that their oil temperature should read between 160-180 degrees F when they are driving. However, this is not always the case. Depending on the type of vehicle you have, your oil temp gauge may read differently.
For example, if you have a newer car with a synthetic oil, your oil temp gauge may read higher than 160-180 degrees F. This is because synthetic oils have a higher boiling point and can withstand higher temperatures before breaking down.
What is the Average Oil Temperature?
The average oil temperature is typically between 180-200 degrees Fahrenheit. However, this can vary depending on the specific oil being used and the operating conditions of the engine. It is important to check your owner's manual or consult with a professional to determine the ideal oil temperature for your particular engine.
What Is A Safe Engine Oil Temperature?
What is Normal Engine Oil Temperature in Celsius
Assuming you would like a blog post discussing what is considered a normal engine oil temperature: Most engines are designed to operate within a specific temperature range, and your engine oil plays a key role in maintaining these temperatures. While the ideal operating temperature for your engine will vary depending on the make and model, most fall within a range of 190-220 degrees Fahrenheit (88-104 degrees Celsius).
During colder weather, it's not uncommon for your engine oil to struggle to reach its ideal operating temperature. This is due to the fact that thicker oils are more viscous and take longer to circulate throughout your engine. However, once your oil warms up it should be able to maintain the desired temperature range relatively easily.
If you notice that your engine oil frequently struggles to reach or maintain its ideal operating temperature, it could be an indication of a larger problem. Make sure to have your car checked out by a professional to diagnose any potential issues.
Normal Engine Oil Temperature Fahrenheit
As anyone who's driven a car knows, the engine is the heart of the vehicle. It needs to be well-maintained in order to keep the car running smoothly and efficiently. Part of maintaining your engine includes knowing what the ideal operating temperature is for your specific make and model.
For most engines, the normal operating temperature is between 195-225 degrees Fahrenheit. Of course, this can vary slightly depending on the outside temperature and how hard the engine is working. If you're driving in hot weather or pulling a heavy load, your engine will likely run a little hotter than usual.
Conversely, if it's cold out or you're just puttering around town, your engine will probably run a bit cooler than its ideal temp. It's important to keep an eye on your engine's temperature gauge (usually located on the dashboard) and make sure it stays within the normal range. If it starts to creep into the red zone, that means your engine is overheating and you need to take action immediately!
Pull over to a safe spot, turn off the engine, and call for roadside assistance. Trying to drive with an overheated engine can do serious damage and may even cause it to seize up completely. So there you have it – now you know what normal oil temperatures are for most engines and how to tell if yours is running too hot.
Keep an eye on that gauge and happy motoring!
Normal Oil Temperature Vw
If you own a VW, it's important to know what the normal oil temperature range is for your vehicle. Depending on the model of VW, this can range from about 195-degrees Fahrenheit to 205-degrees Fahrenheit. If you notice that your oil temperature is consistently outside of this range, it's important to have your vehicle checked out by a professional as soon as possible.
Car Oil Temperature 100 Degrees
If your car's oil temperature is 100 degrees, it means that the oil is too hot and needs to be cooled down. This can happen for a number of reasons, such as if the engine is running too hot or if the car has been driven hard for an extended period of time. If you see this warning light on your dashboard, it's important to pull over and let the car cool down before continuing to drive.
Conclusion
Motor oil has a range of temperatures it should operate within, depending on its grade and viscosity. For most passenger vehicles, the normal oil temperature range is between 195 to 220 degrees Fahrenheit. However, synthetic motor oils can withstand higher temperatures than traditional motor oils.
It's important to keep an eye on your vehicle's oil temperature to ensure it's running properly and not overworking the engine.

Debug on a user without debug permissions
In a well protected system, normal users don't have debug permissions. Very often, this makes it harder for ABAP programmers to help solve the users' problems, not being able to debug directly in their session.
But there is a legit, albeit obscure, work-around for this problem.

Undo in debugger layout
Although a substantial part of an ABAP programmer time is spent debugging code, most programmers I know don't invest much in getting to know the ABAP debugger. Maybe because they spent too many years working with its previous version which was truly archaic and worthless. But the new one can do much more than you usually ask of it. And Abapinho intends to teach you how.
Today I'll teach you just a simple key.

Debugging with baby steps
When you debug you use F5 key to move to the next statement (or go inside a sub-routine). But imagine an IF with multiple conditions:
IF A = 1 AND B = 2 AND C = 3.
 WRITE 'I like the word glauc'.
ENDIF.
When you debug through that IF using F5 and one of the expressions is false you'll step out of the IF without knowing which of the three was false.
But the new debugger has a new very neat functionality which can help you to better understand what happened there.

Can you really do it right the first time?
Checkpoints is a very powerful ABAP framework which almost nobody uses. Why? Probably for the same reason hardly anyone listens to Sun Ra and knows that Frank Zappa has 102 albums. Because, even though really good, it's obscure and not commercial. Checkpoints são, indeed, really good and not commercial. But they should be more like Mozart and the Beach Boys which are both good and commercial.

STA Ticket System improve SAP incident handling times
Today we have a guest, Tamás Holics. He owns STA Consulting, a Hungarian company which has created 2 very interesting SAP products. In this article Tamás presents the STA Ticket System.
The problem
A lot of time is wasted in SAP software testing and maintenance processes due to incomplete or incorrect error reports from users and testers. Support people (analysts, developers) usually have to ask for more information about the error. This takes a lot of valuable working time from both the reporters of the error and support people. Solving the problem is often blocked until every information is available.

Request Based Debugging
If you look up the UNAME system variable in debug within a RFC call you may think it kind of odd to find a username that is not your own. What happens is that the system adopts a specific username for remote calls and a new session is started. A new session implies a new execution context and, hence, all our strategically placed breakpoints will no longer be recognised.
This problem can hinder a simple debug forcing us to run through the code looking for THAT remote call to THAT particular system.
SAP has a solution.

, says Khabbaza. "Encourage the person who is recovering to listen to their body. When they feel ready to resume their normal activities — whether that's running, biking, or walking — they should do so," he says.
When a person is sick, their body becomes deconditioned, and getting "back in the saddle" is an important step in the recovery process. But they shouldn't expect to be able to just jump back in where they left off fitness-wise; they need to be patient and not push too hard, especially in the first few weeks, Khabbaza adds.
People who have other chronic conditions or who had a more severe course of COVID-19 should check with their healthcare provider before resuming activities, according to UCLA Health.
A person can have lingering symptoms or health effects that continue after the normal recovery period, known as post-COVID conditions (PCC) or long COVID. Researchers are still learning about long COVID and how to best treat it. If the person you are caring for has bothersome symptoms at least four weeks after infection, they should check in with their primary care doctor, according to the CDC.

Northern Wisconsin high schoolers learn with stem cells, UW researchers
Eighteen top science students from northern Wisconsin high schools have earned the opportunity to hone their laboratory skills and work alongside leading researchers from the University of Wisconsin–Madison at a summer science camp focused on stem cells.
Hosted by the Morgridge Institute for Research, a nonprofit biomedical research institute affiliated with UW–Madison, the four-day summer science camp starts today and will cover a number of hands-on activities. Students will participate in neural and cardiac differentiation labs, attend lectures from top UW–Madison researchers and enjoy some time for fun and relaxation at campus attractions including Union South and the Kohl Center.
Students will work with both human embryonic stem cells and induced pluripotent stem cells. Human embryonic stem cells are blank-slate, or pluripotent, cells that have the capacity to differentiate into any of the more than 220 cell types in the human body. Induced pluripotent stem cells derived from reprogrammed skin cells show some differences from human embryonic stem cells and also are the focus of much promising research for human health and pharmaceutical development.
Human embryonic stem cells were first isolated on the UW–Madison campus by James Thomson, who also was among the first to create induced pluripotent stem cells. Today, Wisconsin researchers are considered leaders in developing an understanding of these cells as they search for treatments and cures for diseases such as diabetes, Parkinson's and heart disease. Wisconsin scientists also are pioneering the use of stem cells to help develop better and safer medicines.
Students will use stem cell lines that were established approximately 10 years ago. These cells continue to play a vital role in international research because of their flexibility and well-documented performance characteristics.
The students participating in the camp, held July 16-19, attend schools and educational centers including Cornell High School; Forward Service Corp.; Oconto Falls High School; Oneida Nation High School; and Rhinelander High School. The students earned the honor of attending through their classroom performance and dedication during months of preparatory study.
Students participating in the stem cell camp are:
- Cornell High School: Travis Anderson; Hannah Ash; Peter Duerst; Ryan Williams; Robert Duerst (teacher);
- Forward Service Corp.: Tyler Fenner; Joshua Jezeski; Samantha Nighorn; Bobbi Jo Schauer; Sarah Jo Dahlstrom (chaperone);
- Oconto Falls High School: Olivia Carlton; Justice Graf; Colin Sigmund; JoAnn Miller (teacher);
- Oneida Nation High School: Delylla Fredenberg; Rachel Ninham; Eveyonna Ortega; Becky Nutt (teacher); and
- Rhinelander High School: Matt Anderson; Ben Eversman; Sam O'Melia; Tyler Thorsen; Kay Coates (teacher).
The stem cell science camp was designed to provide an enrichment experience in an advanced scientific field while introducing promising students to the variety of academic opportunities on the UW–Madison campus.
"Through the camp, we are able to provide students with an in-depth opportunity to broaden their horizons in science, technology and medicine while highlighting the tremendous career opportunities in these rapidly growing fields," says Rupa Shevde, a senior scientist and director of outreach experiences for the Morgridge Institute for Research. "The students benefit from learning about the cutting-edge research that is going on while at the same time gaining hands-on experience with stem cells and other critically important research tools. Introducing the students to stem cells allows us to teach a variety of concepts including the genetic aspects of human diseases and important ethical considerations for researchers."
This summer's stem cell science camp also will feature lectures and presentations from a number of UW–Madison stem cell researchers, including:
- Anita Bhattacharyya, senior scientist, Waisman Center;
- Wendy C. Crone, professor of engineering physics, biomedical engineering and materials science and engineering, and associate dean for graduate education, Graduate School;
- Kevin Eliceiri, director, Laboratory for Optical and Computational Instrumentation;
- Tim Kamp, associate professor of medicine and physiology;
- William Murphy, associate professor of biomedical engineering and orthopedics and rehabilitation, associate director of the Stem Cell & Regenerative Medicine Center; and
- Sean Palecek, associate professor of chemical and biological engineering and biomedical engineering.


Introduction to HaXml
A quick introduction into the HaXml library, reading data from XML and representing them as Haskell types
I was looking for a HaXml tutorial or code examples on the web but I could not find any description of the basic idea behind the library. There are a few tutorials out there, but their focus is more on the power of combinators than on the library basics. There is also a code fragment in the book real-world haskell but (at the time of writing this post) it is outdated.
The aim of this tutorial is to describe the basic HaXml functionality - reading XML data from a file into custom types and saving the data from these types back to another file.
What we want to achieve is:
main :: IO ()
main = do
 students <- fReadXml "sample-in.xml" :: IO Students
 print students
 fWriteXml "sample-out.xml" students
The sample-in.xml looks like this:

 Zachary Popme

 Daria Marchenko
First we need to install the library with:
cabal update
cabal install haxml
We could also work with the XML data directly and not map it to any types. This can be achieved with the ANYContent type. We could read everything from the XML like this:
main :: IO ()
main = do
 c <- fReadXml "sample-in.xml" :: IO ANYContent
 print c
Nonetheless, our goal is to map the XML to custom data-types. These types will have 1 to 1 correspondence with the XML data, although this is of course not necessary.
data Students = Students {enrolled :: [Student]} deriving Show
data Student = Student {name :: String, gender :: String, address :: Address} deriving Show
data Address = Address {street :: String, number :: Int} deriving Show
HaXml reads the contents (elements, attributes, comments, declarations etc.) of any XML and wraps it into HaXml data-types. For illustration purposes we can have a look at the Address element:
CElem (Elem (N "Address") []
 CString False "\n\t\t\t",
 CElem (Elem (N "street") [] [CString False "uptown"]),
 CElem (Elem (N "number") [] [CString False "4"]),
 CString False "\n\t\t" ]),
 CString False "\n\t" ]),
 CString False "\n"
We need a way to extract the data from these HaXml types and store them in our types. We can do it by implementing two typeclasses HTypeable and XmlContent.
Let's describe these in turn.
The class is quite simple:
class HTypeable a where
toHType :: a -> HType
HType adds additional metadata to the type it augments. For example:
instance HTypeable Integer where
toHType _ = Prim "Integer" "integer"
The Prim type holds the XML-element name for a given primitive ("integer" in case of the type Integer). HaXml takes advantage of metadata in HTypes when mapping from Haskell types to XML.
We have defined three records - Student, Students and Address. For each record we have to define an instance of HTypeable. Let's begin with Address:
instance HTypeable Address where
toHType (Address s n) = Defined "Address" [] [Constr "Address" [] [toHType s, toHType n]]
The arguments to the Defined data constructor are as follows:
 - name of type,
 - a list of HTypes of the type variables,
 - a list of all data constructors for the type.
The Constr has 3 arguments:
 - name of the constructor (will be used as the XML tag-name),
 - a list of HTypes of the type variables,
 - list of all arguments to the data constructor (as HTypes).
A more detailed description of Constr can be found in the code.
The other two instances are similar to the first one:
instance HTypeable Students where
toHType (Students ss) = Defined "Students" [] [Constr "Students" [] [toHType ss]]
instance HTypeable Student where
toHType s =
 let Student n g a = s in Defined "Student" [] [Constr "Student" [] [toHType n, toHType g, toHType a]]
Now we can start defining the XmlContent instances which have two functions - parseContents (from XML to types) and toContents (from types to XML).
instance XmlContent Address where
 parseContents = inElement "Address" (Address <$> parseStreet <*> parseNumber)
 parseStreet = inElement "street" text
 parseNumber = read <$> inElement "number" text
 toContents a@(Address s n) =
 [mkElemC (showConstr 0 $ toHType a) [mkElemC "street" $ toText s, mkElemC "number" $ toText. show $ n]]
Let's first look at toContents. Its implementation will be (almost) the same in all instances. toContents is called when a new Address XML-element should be created. We define the XML-element with mkElemC. The first argument is the tag-name (we can use the showConstr function which pulls the name from a HType). Afterwards we create two sub-elements - "street" and "number".
parseContents traverses the HaXml types which wrap the XML data. It uses the HaXml functions to navigate through all the types like CElem, Elem, CString etc. (we saw those in the example above). The inElement function are basically two functions - element which moves to the next XML-element and interior which goes "into" the contents of that element. The text function extracts the text from the element. Since XmlContent is a functor (inElement returns XMLParser a) we can use the applicative operators as shown above.
The Students instance is pretty much the same:
instance XmlContent Students where
 parseContents = inElement "Students" (Students <$> parseContents)
 toContents v@(Students ss) =
 [mkElemC (showConstr 0 $ toHType v) (toContents ss)]
For reading and writing attribute values I'll define helper functions (if there is a better HaXml-way to do it let me know!). The first argument of attrToText is the name of the attribute, the second is a list of attributes which we go through in order to find an attribute with this name. If no attribute is found, the function returns Nothing.
mkAttrElemC creates a CElem with the appropriate attributes.
attrToText :: String -> [Attributes] -> Maybe String
attrToText n as = foldl1 (<|>) attrText
 where attrText = map (fromAttrToStr n) as
mkAttrElemC :: String -> [Attribute] -> [Content ()] -> Content ()
mkAttrElemC x as cs = CElem (Elem (N x) as cs) ()
instance XmlContent Student where
 parseContents = do
 e <- element ["Student"]
 interior e (Student <$> parseName <*> parseGender e <*> parseContents )
 parseName = inElement "name" text
 parseGender e = return $ fromMaybe "unknown" $ attrToText "gender" $ attrs e
 toContents v@(Student n g a) =
 [mkAttrElemC (showConstr 0 $ toHType v) [mkAttr "gender" g] (mkElemC "name" (toText n) : toContents a)]
We read the name (parseName), afterwards we use the HaXml Student element e (it's just an Elem type) for reading all of its attributes and return the value of "gender" attribute. The last function is parseContents which will trigger parseContents in the Address XmlContent instance.
Generating code with DrIFT
The last point to mention is that we can partially automate generating this boilerplate. This can be achieved with DrIFT.
Install with:
cabal update
cabal install drift
We prepare the template:
{-!for Address derive : XmlContent!-}
{-!for Students derive : XmlContent!-}
{-!for Student derive : XmlContent!-}
Now we can generate all the instances by calling:
DrIFT xmlparser.hs
from the command line. It prints the generated source code to stdout. A full working example can be found here xmlparser.hs

To modify the Message Composition window, edit the rtfeditor.html file.
Functionally, rtfeditor.html is called by comp_fs_lr.html. This function assembles the code and assigns the functions to the graphics by calling WMtoolbar() in main.js that also handles colors and text-only versions. The rtfeditor.html file generates the "To", "Cc", and "Bcc" control area by calling the i18n_compose_controls() in /i18n.js.
Example 5–6 shows the necessary changes to be made in the file en/i18n.js for changing the text "Recipients" to "Send to".

TP(1) General Commands Manual TP(1)
NAME
 tp - manipulate tape archive
SYNOPSIS
 tp [ key ] [ name ... ]
DESCRIPTION
 Tp saves and restores files on DECtape or magtape. Its actions are
 controlled by the key argument. The key is a string of characters con‐
 taining at most one function letter and possibly one or more function
 modifiers. Other arguments to the command are file or directory names
 specifying which files are to be dumped, restored, or listed. In all
 cases, appearance of a directory name refers to the files and (recur‐
 sively) subdirectories of that directory.
 The function portion of the key is specified by one of the following
 letters:
 r The named files are written on the tape. If files with the
 same names already exist, they are replaced. 'Same' is deter‐
 mined by string comparison, so './abc' can never be the same as
 '/usr/dmr/abc' even if '/usr/dmr' is the current directory. If
 no file argument is given, '.' is the default.
 u updates the tape. u is like r, but a file is replaced only if
 its modification date is later than the date stored on the
 tape; that is to say, if it has changed since it was dumped. u
 is the default command if none is given.
 d deletes the named files from the tape. At least one name argu‐
 ment must be given. This function is not permitted on mag‐
 tapes.
 x extracts the named files from the tape to the file system. The
 owner and mode are restored. If no file argument is given, the
 entire contents of the tape are extracted.
 t lists the names of the specified files. If no file argument is
 given, the entire contents of the tape is listed.
 The following characters may be used in addition to the letter which
 selects the function desired.
 m Specifies magtape as opposed to DECtape.
 0,...,7 This modifier selects the drive on which the tape is mounted.
 For DECtape, x is default; for magtape '0' is the default.
 v Normally tp does its work silently. The v (verbose) option
 causes it to type the name of each file it treats preceded by
 the function letter. With the t function, v gives more in‐
 formation about the tape entries than just the name.
 c means a fresh dump is being created; the tape directory is
 cleared before beginning. Usable only with r and u. This
 option is assumed with magtape since it is impossible to se‐
 lectively overwrite magtape.
 i Errors reading and writing the tape are noted, but no action
 is taken. Normally, errors cause a return to the command
 level.
 f Use the first named file, rather than a tape, as the archive.
 This option is known to work only with x.
 w causes tp to pause before treating each file, type the in‐
 dicative letter and the file name (as with v) and await the
 user's response. Response y means 'yes', so the file is
 treated. Null response means 'no', and the file does not
 take part in whatever is being done. Response x means
 'exit'; the tp command terminates immediately. In the x
 function, files previously asked about have been extracted
 already. With r, u, and d no change has been made to the
 tape.
FILES
 /dev/tap?
 /dev/mt?
SEE ALSO
 ar(1), tar(1)
DIAGNOSTICS
 Several; the non-obvious one is 'Phase error', which means the file
 changed after it was selected for dumping but before it was dumped.
BUGS
 A single file with several links to it is treated like several files.
 Binary-coded control information makes magnetic tapes written by tp
 difficult to carry to other machines; tar(1) avoids the problem.
