for threads belonging to the same process; maybe we just need to generalize this "enhanced" highlighting behavior to user-defined groups.
 [Khouzam] Yes, this is probably an obvious thing for groups, now that we have it for the current Multicore Visualizer.
 7. The Multicore Visualizer should have the ability to zoom, and based on the zoom level, the view could automatically add more information because there is more space available. So the level of detail will increase with the zoom level
 [WRS] True -- the Multicore Visualizer already handles being made too small by omitting text labels and other detail. We can also go in the other direction and add more detail if we are given more real-estate. I wouldn't go too far in this direction, though, because then you'll wind up with people complaining about having to keep zooming in and out to see more and less detail. We might want to consider instead putting some information on separate, selectable "overlays" or "layers", so that one can select what's needed without having to make the visualizer bigger to accommodate it.
 [Khouzam] Valid point. I thought automatically adding more information as the user zoomed-in could be user-friendly. The "layer" concept should come first. Automatically turning on layers is something we could then discuss.
 - A concept of grid-in-grid would allow separating each Multicore Visualizer element into sub-elements like a box for each register, or variable. As an example, this could be applied to the zoom level, where we could zoom out of the Multicore Visualizer of a single chip and then show a Visualization of many chips, each one showing a grid of cores as a sub-element.
 [WRS] We might also allow multiple Visualizer views, as someone suggested at the EclipseCon talk, and then have a "Processor Visualizer" view, so that one can click around in the Multicore Visualizer, and see more detail about the currently selected cpu/core in the processor visualizer -- again, as a way to avoid the user having to constantly zoom in and out to see the necessary detail.
 [Khouzam] That sounds good. I'm a little worried that people wouldn't realize they could do this by using multiple views though. But I like that one view could show a higher level, and then using the synchronization with the debug view, a second view could be 'zoomed' on the currently selected core. Then, with Pin&Clone, you could even have multiple views, zoomed on different cores at the same time.
 8. Synchronized resume and step must be supported in the Visualizer view. A synchronized resume or step is performed on multiple cores/processes/threads while keeping the progression in lock-step where each entity progresses at the exact same ratio.
 [WRS] If it's like synchronized resume of multiple threads, that might be a back-end/debugger feature, and below the visualizer's radar.
 [Khouzam] You are right that the actual implementation of the synchronized resume/step must be performed by the back-end. But CDT will need to provide UI to support this operation.
 - The concept of a leader for a synchronized operation is necessary. The leader is the entity part of the synchronized operation that will indicate when the operation has completed. For example, if two threads are stepped in a synchronized manner, the selected leader thread is the one for which the step must finish to indicate the operation is done.
 - The Visualizer view should support soft-groups. A soft-group is a group that is defined for a single operation; for example, a drag-selection or a multi-selection define a soft-group. Soft-groups needs a way to select a leader for synchronized operations. For multi-select, the last selection could be the leader. For drag-selection, the user could specify the leader by un-selecting an entity and then re-selecting it, making it the last one part of the selection.
 9. Building blocks of the view should not be limited to cores, but should be a generic building block that the user can name, set the size, specify the content. The content needs to be based on what the backend knows: "fundamental building blocks", i.e., threads, cores, chips, etc.
 - The Visualizer view could have a concept of widgets which already exists or can be created.
 - Configuration may need to be done at different levels. This means that some configuration would be done by the chip provider, e.g., the number of cores to show, other hardware entries to show; while other configuration could be done by the installer, e.g., which subset of cores to actually show the team of developers; and even more configuration at the user-level, e.g., which register to show
 [WRS] Again, is this extending the Multicore Visualizer, or providing "building block" support for custom views in the framework? We'd need some examples of what people would like to achieve to know where this building block / configuration support should properly live.
 [Khouzam] This is an ambitions and vague requirement. I suggest we revisit it once we have better support for customizations and layers.
 10. When doing drag-selection, it would be convenient to also drag-deselect (DONE)

Multi-chip debugging
The CDT community is mostly focused in enabling multi-core debugging to the CDT. However, support for multi-chip debugging would also be interesting where you have chips->cores->processes->threads. Current solution will be to use multiple debug sessions (multiple GDBs). We will need GDB support to have a better integrated solution using a single GDB; using a single GDB would allow, for example, to support synchronous control of different chips.
Watch view
A new 'Watch' view would be a good addition to the CDT. This view (see 'watch' command in unix) would provide a way for the user to request that a console command or set of commands be executed at specific times such as:
 - after every state-changing operation
 - at a periodic interval
 - on particular events (suspend, running)
 - based on filters (when thread1 stops)
 - watchpoints
 - catchpoints
 - breakpoints
 - etc
It may be good to look at what is provide by the IAR Debugger where it is apparently possible to have a watch window which can be used to watch expressions which are updated in a specifiable interval.
 1. This concept could be extended to eclipse operations, like refreshing a view automatically on those triggers
 2. We could mimic a breakpoint condition/commands to allow the user to 'run a script' whenever one of the above triggers occurs. This script could be a gdb python script
 3. The view should always refresh if the context changes, unless it is pinned
 4. This watch view would handle its output in the following way:
 1. There should be a standard scrolling mode
 2. There should also be a fixed size output that only shows the last output.We could then "page up" to jump to the previous output repeatedly.
 3. We should have a toggle to choose between the two modes
 5. Another enhancement would be to highlight the changes from the new output compared to the previous output. This would allow the user to quickly see what changes. A nice way of showing change dynamically is firefox' javascript debugger who shows the new html code written in red to indicate what the single step actually created in html. This could be disabled by the user if the data is too different.
Enhancements to the Modules view
The modules view is used to show the list of currently used dynamically linked libraries. The view is updated whenever a new library is loaded or an existing one is unloaded (although there is currently a bug that makes the update not happen). The view also shows information about the libraries such as file location, base address and size. Below are some requirements for the Modules view.
Note that the Watch view described above may be more valuable than the below enhancements
 1. The view should be context-aware and show what is currently loaded based on the current context (process/core)
 2. Although modules can change when a process/core is running, it only needs to be refreshed once the process/core stops, just like for variables and such.
 3. Refresh of the view should be based on GDB's new MI events: =lib-loaded and =lib-unloaded
 4. Since the modules view is so simple for GDB, as to repeatedly issue the 'info sharedlib' command, the current behavior of the view could be replaced by the
new proposed Watch view which would send the 'info sharedlib' command upon the proper triggers.
Enhancements to Disassembly view
The Disassemby view shows the running code as disassembled by GDB. The view allows navigating through that disassembled code, to set breakpoints/tracepoints, and to show the disassembled code interleaved with source code. Below are some requirements relevant to the Disassembly view.
 1. Should support different memory spaces and allow the user to choose which memory space to show the disassembly for.
 2. Instructions that correspond to the same source code line should be identified. An example is shading them to the same color, and/or a vertical bar in the margin (see ARM product http://inf

Abstract
The lithological-facies factor is considered with the aim of studying the natural and geological conditions in which hydrogen sulfide waters are formed in gas and oil fields in the artesian basins of the Republic of Uzbekistan. The distribution of hydrogen sulfide waters is closely related to the areas of joint development of halogen rocks and oil and gas complexes. Since the term "paragenesis" refers to the joint finding of minerals or chemical elements genetically related, this map is a map of the paragenesis of hydrogen sulfide waters with evaporites and oil and gas complexes. In the absence of one of the necessary conditions (sulfates or petroleum organics), hydrogen sulfide waters of high concentration are not formed. Hydrogen sulfide waters in the identified anticlinal structures are formed due to the presence of insignificant gas and oil deposits, which are not of industrial importance

IZA DP No. 11076: Income Increase and Moving to a Better Neighbourhood: An Enquiry into Ethnic Differences in Finland
Concentration to disadvantaged neighbourhoods may hinder immigrants' opportunities for social integration, so equal chances of translating available economic resources into mobility to less disadvantaged neighbourhoods are important. This paper adds to existing research on exits from poor neighbourhoods by focusing on the effects of income increase on residential mobility. We analyse intra-urban residential mobility from low-income neighbourhoods into non-low-income neighbourhoods among immigrants and native-born residents in three urban regions in Finland. We use longitudinal register data for the 2004–2014 period for the full Finnish population, allowing a dynamic analysis of changes in income and neighbourhood of residence. Based on multinomial logit modelling of migration outcomes, we found that an increase in income is associated with moving both to low-income and non-low-income areas even when controlling for initial income level. Upward income mobility was connected to exit from low-income areas in a quite similar way among immigrants and native-born Finns. The findings suggest that policies e.g. improving the labour market opportunities of immigrants are effective in reduction of residential segregation. However, we were not able to completely explain the differences between native-born Finns and immigrants in moving patterns. The differences between the cities were opposite for immigrants and native-born Finns, corresponding to differences in immigration history and levels of ethnic segregation. Therefore, the local context matters for spatial integration outcomes.

This past Wednesday, I had the opportunity to see Hamilton in Chicago, Illinois (spoiler alert: it was INCREDIBLE). I've been looking forward to the show ever since I purchased the tickets in early January; every few weeks from that point onward, I have been periodically checking up on Hamilton-related news online. During one of these online searches, I stumbled upon a February 2017 article titled "A packed 'Hamilton' matinee — all Chicago Public School students and their teachers."
So, what exactly is the Hamilton Education Program? As the program's webpage explains:
"In October 2015, Hamilton producer Jeffrey Seller and Hamilton creator Lin-Manuel Miranda, The Rockefeller Foundation, NYC Department of Education, and the Gilder Lehrman Institute announced an educational partnership that will provide 20,000 NYC Title I public school students with the opportunity to see Hamilton on Broadway and will integrate the show into classroom studies. This educational initiative, running from 2016 to 2017, is made possible through a $1.46 million grant by The Rockefeller Foundation to the Gilder Lehrman Institute."
What really interested me was how the program integrates the show into classroom studies. This experience is so much more than a field trip: before the class even travels to the matinee, they learn in-depth about both the chunk of American history that surrounds Hamilton and how Lin-Manuel Miranda utilized primary sources from the era to create the show itself. Even more exciting, students are given the tools (through an exclusive student website that features extensive Hamilton-related primary sources) to research him further and to create their own performance pieces. Before the matinees, students are encouraged to perform their original pieces on stage. The Gilder Lehrman Institute says it best: "This innovative program integrating history and performing arts will allow teachers to bring American history to the classroom in a new way and help students find their own connections to the Founding Era."
The video above is a snippet of the kind of creative performances student participants in the Hamilton Education Program can create and showcase. How cool is this?
What about the cost? Hamilton Chicago ticket prices are steep – Broadway ticket prices are outrageous. For the average public school student, watching a musical like Hamilton is an incredibly costly (and perhaps unrealistic) dream. In an interview with the New York Times, Lin-Manuel Miranda explains one of his main priorities as the show picked up more traction became how to make the play more accessible to young people. Thanks to the generous Rockefeller Foundation grant given to the program, students can watch the very play that many theatre-goers are willing to pay thousands of dollars to go watch for essentially the price of a movie ticket ($10).
As the New York Times article I referenced a little earlier reveals, the Hamilton Education Program is the "largest for a single production and the first to so fully involve the school district."
I am amazed by the Hamilton Education Program and its dedication towards making both the theatre and education accessible to public school students in a way it has never been before. Although I can't expect the next slew of wildly successful Broadway musicals to be fully applicable to the classroom, I hope that this program and its message will be further replicated in the future through other creative mediums – such as movies.

A Critical evaluation of methods for computing small failure probabilities for ductile piping components
This paper focuses on the application of the failure assessment diagram (FAD) approach to accomplish robust and reliable calculations of small failure probabilities, as required for safety relevant nuclear components. Specifically, the firstand second-order reliability methods (FORM, SORM) as well as different sampling algorithms are investigated as to their performance and numerical stability. In particular, computational problems are noticed in the assessment range corresponding to the transition from ductile fracture to plastic collapse which is a typical operating regime for ferritic piping. Numerical errors are found to result due to the occurrence of multiple design points in the FORM procedure, thus leading to an underestimation of failure probabilities. Subsequent benchmark calculations reveal a high efficiency of the improved numerical algorithms within a very broad range of failure probabilities. Another aspect considered in the paper is the application of FOR M/SORM to the assessment of crack instability taking into account the scatter in crack resistance curves. Finally, the methods and computer tools developed within the framework of this research are applied for evaluating some pipe burst tests described in the literature.

- Pitchers have been deceiving batters with tricks and cheats since baseball began.
- Typical cheating tactics include scuffing the ball and putting foreign substances on it.
- Current rules forbid tampering with the baseball at all.
When Tampa Bay Ray's relief pitcher Joel Peralta was ejected from a game last week because there was pine tar on his mitt, he joined a century-long list of Major League baseball pitchers who have done whatever they needed to do to get the upper hand.
From spitballs to scuffed balls, pitchers have been cheating as long as there have been rules.
Whether Peralta's technique actually gave him any edge, though, is up for debate. No one has ever studied the effects of pine tar on the flight of a baseball. And so far, nothing egregious has shown up in Peralta's pitching stats to suggest that his cheating techniques have given him a leg up.
Still, rules are rules, and they exist for a reason. Theoretically, putting any kind of foreign substance on a ball could make it move erratically, confusing and possibly even endangering batters.
"Not being allowed to doctor the ball seems like a sensible rule to me," said Alan Nathan, a physicist at the University of Illinois at Urbana-Champagne, and an expert on the physics of baseball. "You can affect the trajectory of the baseball by doctoring it."
There are two main ways to fiddle with a ball, Nathan said. The first is to add lubrication to reduce friction between the ball and the pitcher's fingers. That, in turn, diminishes the throw's natural backspin, making the ball drop more quickly than a normal fastball would. This is what makes the spitball so infamous.
The second category of messing with a baseball is to roughen up its smooth surfaces. Whether scuffed with an emery board or gouged with a fingernail, compromised balls tend to break in the direction of the scratched side.
In the early days of baseball, pitchers were free to do whatever they wanted -- and they did, said Dave Baldwin, a retired Major League baseball pitcher and author of the baseball memoir "Snake Jazz." Tricks included putting licorice on the ball to make it darker and harder for batters to see, sticking pins in the ball, or smudging substances on one side to make the wobble or move strangely.
Then, in 1920, Yankees pitcher Carl Mays threw an extraordinarily hard submarine pitch, which rose from ground level, struck Cleveland Indians batter Ray Chapman in the head, and killed him. Chapman didn't react to the pitch at all. It appeared that he didn't even see it coming.
Chapman's death led to a swift and dramatic shift in the rules of baseball. Pitchers could no longer put foreign substances on the ball or their hands other than rosin, which is an approved powder that helps make sweaty hands less slippery. And when balls got dirty during play, umpires replaced them.
Instead of putting a halt to the cheating, though, the new rules only drove pitchers to get sneakier about their tricks. In the 1960s and 70s, when Baldwin was playing, pitchers used Vaseline to lubricate balls until K-Y Jelly came on the market and became the baseball-moistener of choice. The water-based lubricant evaporated during flight, making it almost impossible for umps to detect.
Other times, pitchers coated the ball with talcum powder, which was white and -- unlike baby powder -- odorless. The powder would fly off in flight, and it could make balls sink more quickly than expected. Pitchers might hide small bits of emery board on their belts or under their caps to sneak on a scuff mark or two. Even today, catchers may intentionally throw a ball that bounces right before a game begins, hoping the umpires won't notice.
Pitchers aren't the only ones who try to cheat, Baldwin added. Batters are notorious for putting cork or metal rods in their bats to change their weight or flexibility. And, because doctored bats are harder to detect than doctored balls, he suspects that batters cheat more often than pitchers do.
To work around the ever-watchful eyes of umpires and TV cameras, modern-day pitchers have turned instead to more innovative forms of pitching. Throws like the split-finger fastball -- which suddenly drops when it reaches the batter -- or the knuckleball, which spins less than a typical ball, are perfectly legal, but they can keep a batter guessing.
As for Peralta's pine-tar trick, the pitcher's motivation remains a mystery.
"Pine tar is very easy to detect," Baldwin said. "It just doesn't make any sense why any pitcher would try to use that."

La Jardinera de la Esperanza (The Gardener of Hope)
La Jardinera de la Esperanza, depicts a young girl lying on garden patio steps, cultivating a variety of plant pots. The sculpture is sited four metres beneath the surface Punta Nizuc, Cancun. The pots are propagated with live coral cuttings rescued from areas of the reef system damaged by storms and human activity. This technique, a well-established procedure in reef conservation, rescues damaged coral fragments by providing a suitable new substrate.
The sculpture, a synthesis between art and science, conveys a message of hope and prosperity, portraying human intervention as positive and regenerating. The young Girl symbolizes a new, revitalized kinship with the environment, a role model for future generations. The interaction between the inanimate and living forms highlights a potential symbiotic relationship with the life systems of the underwater world. Over the past few decades we have lost over 40% of our natural coral reefs. Scientists predict a permanent demise of 80% by 2050. The Gardner of Hope is designed to focus attention on this important, often forgotten, ecological issue.
Built into the base of the sculpture are specialized habitat spaces designed to encourage individual types of marine creatures such as moray eels, juvenile fish and lobsters.

Tough scrutiny for tip plan
The proposal for a new Esperance landfill will be subject to the highest level of Environmental Protection Authority scrutiny.
In the authority's decision to undertake a public environmental review, chairman Dr Tom Hatton said the proposed tip had the potential to affect surface water quality and flows, as well as soil and groundwater quality because of leachate seepage.
Dr Hatton said there were also potential effects of odour, noise, dust and landfill gas emissions to consider.
"This proposal has a high level of public interest," he said.
"Detailed assessment is required to determine the extent of the proposal's direct and indirect impacts, and how the environmental issues could be managed."
The Shire of Esperance council wants to build the new waste management facility at Lot 12 Kirwan Road, Merivale.
The authority has received 84 submissions about the proposal, with 80 asking for the public environmental review.
The council yesterday said it was one of those asking for this highest level of assessment.
Shire president Victoria Brown said the environment was a council priority, and any potential impact must be investigated fully to determine if the location was the right place to build a landfill site.
"We do not want to build a landfill site in a location that may cause damage to our beautiful natural assets," she said.
"A modern waste management facility is always going to create angst among those who live nearby and we all need to be certain that a new landfill site will have no significant impact on the surrounding environment, the neighbours and the community."
A motion calling for the abandonment of Lot 12 Kirwan Road as the proposed site was passed at the Shire of Esperance annual electors' meeting on January 30.
Shire of Esperance councillors were to consider the motion at a special meeting taking place last night after the Kalgoorlie Miner went to press.

入植農家からみた干拓地農業の変容過程-名古屋市近郊鍋田干拓地の事例The Changing Process of Farming on Reclaimed Land from the Settlers Point of View--A Case Study of Nabeta Reclaimed Land in the Suburbs of Nagoya City
This research examines the changing process of farming on reclaimed land, as seen from the changing farming conditions of each settler, in the context of national land reclamation, which took place after the Second World War when agricultural production was increasing.As a case study, I researched the background of 136 settlers who started farming in 1962 on Nabeta Reclaimed Land, Aichi Prefecture, situated at the mouth of Kiso River. I examined the following 3 points : (1) settlement conditions of Nabeta Reclaimed Land, (2) the influence of Typhoon hazards from Ise Bay on the farming behavior of settlers and (3) the influence of urbanization from the metropolitan area Nagoya. The results are as follows : 1) There occurred some differences in farming among settlers, depending upon the time of settlement, their native places, the land condition of their farm and their successors. The difference in farming was most greatly influenced by land conditions based on the time of settlement.2) The changing process of farming in Nabeta Reclaimed Land can be divided into 3 periods : 1 st period (commencement of farming), 2nd period (change in farming) and 3 rd period (settlement of farming).3) The farming conditions of settlers diversified gradually over 3 periods : 1 st period→2 nd period→ 3 rd period (Fig. 11). In the 1 st period, conditions were classified into thetype, mainly composed of field husbandry and animal husbandry. In the 3rd period, conditions could be classified into 4 patterns : field husbandry, animal husbandry, part-time farming and abandonment of farming. These were farming patterns that had been already started during the 2 nd period.4) In comparison with other reclaimed lands in Japan, the following can be considered as regional characteristics of Nabeta Reclaimed Land.First, about 20 percent of all settlers were close relatives of those people who were killed by Typhoon Ise Bay. They were less interested in farming, compared to normal settlers, and quite a few of them gave up farming when farming became diversified.Second, about 10 percent of cultivated land (an area of 302 ha) in Nabeta Reclaimed Land turned out to be owned by residents in Nagoya City. Further, settlers have been unable to make the most of accessibility to big markets, because of the lack of community integration in reclaimed land villages and because of the poor performance of specializing in one farm product.

Monsters in the Meadow
By Amy Sellers
32 Pg Picture book: grades 1-4
Pg 1- George was excited about the rainy season approaching. This meant the dry and tasteless grass just outside of his hole would soon turn lush, tasty and tender. His goal every season would be to eat as many of the new sprouts as he could before the grass grew tall, tough and seedy.
Pg 2 -He spun around in the cozy hole he dug which caused a dust cloud to rise. All of the little creatures sharing the tunnel leading to his hole scurried up and out to escape the spoiled air. First Edgar, the cranky squirrel popped his head out of the hole to make sure there were no wolves or snakes lurking near.

Configuration as code
decK can be, or rather should be, used in a CI pipeline to push out configuration
It is advisable to store configuration of Kong in a Git repository (or any other
Version Control System, or VCS) and then perform GitOps on Kong's configuration:
- Any time a change needs to be performed, ask the developer to open a
Pull or Merge Request, which can be reviewed by other humans.
You should use
deck validate and
deck diff commands in the CI to validate
and see if the target changes will be performed or not.
Although unlikely, it is possible that a
deck sync command might fail
even if the above two pass. If this happens, a human has to intervene and
resolve the conflict or error manually.
- Once the configuration change is merged in, the CI should execute
again (to have a log of what is changing), followed by
You should also have a
cronjob in your CI or any other system, which verifies
if the source of truth, meaning Kong's database is in the exact same state as
you want it to be (the state file in VCS repository).
Unless you do this step, you do not have a truly declarative configuration
as your are configure Kong but are never verifying. The system could be
out of sync and can go undetected until another change is performed.
Any time you use decK within an automated environment, including a
deck ping command in the beginning of your script can ease debugging
in the future, as it usually rules out connectivity issues between decK and Kong.


Aquatine lemurian calcite is a calcium carbonate mineral with a trigonal crystal system and a hardness of 3. It is typically a pale to a deep blue-green Calcite from a remote region of Argentina.
Aquatine Lemurian Calcite gets its name from its affinity to the element of water, and to the water-oriented civilization of Lemuria. Whether a physical or etheric place, Lemuria was a realm of the watery qualities—intuition, dreaming, feeling and visionary consciousness.
ALC deeply nourishes the emotional body. It is a strong antidote to stress, fear, worry and anxiety about the future. It soothes and replenishes the etheric body. It enhances dream life and facilitates lucid dreaming. It is ideal for opening up one's capacity for recalling past lives, ancient knowledge and tuning in to the morphic fields of the Earth's past. Those who wish to communicate with whales and dolphins can be aided by Aquatine Lemurian Calcite's capacity to enhance telepathic abilities.
It increases conscious sensitivity through one's energy field. It helps increase awareness of spirit guides and angelic guardians, and allows for easier communication.
ALC has a cooling, pacifying, calming effect on the emotional body. It has the frequency of a mother singing a lullaby or lovingly caressing her child.


Units of Measurement/Acceleration
< Units of Measurement
The SI unit for acceleration is m*s^-2. Acceleration is equal to change in velocity over change in time. Taking a second derivative of speed or first derivative of velocity is equal to acceleration.

|Myra Museum to host talk on Indians of Northern Red River Valley|
The Indians of the northern Red River Valley will be the subject of free lecture Sunday, March 29, sponsored by the Grand Forks County Historical Society.
The speaker will be David Vorland, secretary of the Society. He retired in 2005 after more than 30 years at UND, including stints as an instructor of journalism, director of University Relations, and executive assistant to the President. The illustrated talk begins at 2 p.m. in the Myra Museum on Belmont Road.
Vorland said the Society seeks partners to create a new major exhibit on Indian heritage.
"As with most county museums, we have focused mostly on the period of agricultural and urban settlement," he said. "We also need to tell the story of the earlier history of the junction of the Red and Red Lake Rivers. For thousands of years, this place has been an important landmark and trading center."
A prehistoric Indian presence has even been discovered on the Myra Museum grounds, he said. A recent archeological dig recovered 294 artifacts documenting a hunting camp that existed in 500 A.D.
Vorland's talk will cover the Indian presence from prehistoric times to the beginning of homesteading. Current research, he said, is altering some long-held assumptions.
For example, the evidence no longer supports previous notions about the ferocity of the fighting in northern Minnesota between the Chippewa and the Sioux. Skirmishes occurred, but the tribes also were trading partners. It was not until the adoption of the horse in the mid-1700s that the conflict became deadly in what is now North Dakota.
Eventually the Chippewa dominated the northern part of the Valley, the Sioux the southern part. At first, the Chippewa enjoyed relative prosperity by collaborating with the Pembina traders. But the end of the fur business in the late 1840s, followed by the disappearance of the buffalo, was disastrous for them.
In 1863, the Pembina and Red Lake bands signed a treaty transferring seven million acres of land to the federal government. When the flood of white settlers arrived a few years later, the Chippewa were gone from the Valley.


text: Between 1890 and 1914 Australia became the world's largest market for wool. Wresting this title from London required local brokers to create an ordered market with a central auction room, a uniform sale contract and standard arbitration procedure across a number of separate selling centres. This paper explores the various governance structures created by the Associations in Melbourne, Brisbane and Sydney, to bind co‐operative behaviours. We argue that the dual objects of the Associations, adherence to a uniform price and the operation of a central auction, provided different levels of incentives to firms to co‐operate in each centre. Firms took calculated rational decisions whether to co‐operate with respect to 'price', and different behaviours between centres depended heavily on structural and environmental situations. However, co‐operative behaviours towards supporting the auction system were driven by a combination of pecuniary and altruistic factors. The latter arose from a deep rooted sense of service to promote the wool trade and a belief in its over‐riding national importance.

Drawing from the history of swimwear and specifically the bikini, which was named after an island in the South Pacific where the atomic bomb was tested, Frankenhein Handmade Swimsuits is born. The bikini first appeared in the mid 1940's during a time of war and post war when materials were scarce and people made do with what they already had. Most of the fabric and materials were for military use, and were limited when it came to fashion or garments. When the bikini debuted, its style was not accepted by contemporary culture at the time, but it continues to be an iconic symbol of explosive change.
Taking inspiration from this history and the concept of improvisation, we create up-cycled swimwear from dead stock fabric (left over fabric from larger manufacturing businesses), existing garments, cast off, recycled, and scrap materials. We want to extend the life of cast-off materials headed to the garbage, creating unique, functional swimwear from pre-existing materials in the process.
We embrace the DIY (do it yourself) theory. We can offer suggestions and help to those who would like to build their own surfboard from broken boards or make a swimsuit from recycled materials. We are here to pass on and share inspiration through history, creative energy, problem solving, and recycling/reusing.

The cold temperatures maintained in the Trinity River are beneficial to fish but may be problematic for foothill yellow-legged frogs. TRRP assesses foothill yellow-legged frog breeding distribution, timing, and survival of egg masses. In 2009, 50 egg masses detected in the mainstem river between Lewiston Dam and the North Fork Trinity River. This was the highest count since egg mass surveys began in 2004, and several of the breeding sites were at restoration sites below Canyon Creek. However, it is still minimal compared to some tributaries. Tributaries and the mainstem with colder water had later onset of egg laying and emergence of smaller froglets when compared to warmer tributaries. While relative abundance on the mainstem has increased over the previous four years, reproductive effort is still substantially less than observed on the South or North Fork Trinity River.

In 1999 the average disposable income of Dutch households was nearly 23,500 euro. In terms of purchasing power this was 1.3% more than in the previous year, equalling the growth rate of purchasing power in the period _PHONE_. In 1998 it rose more strongly (2.8%), mainly because of a new form of tax relief for the over-65's.
Disposable household income by source of income
The improvement in purchasing power was largest for employee households. On average households who received their main income from wages had 2.5% more to spend in 1999 than in 1998. Some of these households received a social benefit or pension instead of wages in 1999. For households with income from wages in both 1998 and 1999, purchasing power rose more strongly, namely by 2.7%.
Annual change in purchasing power by source of income
In households which had to depend on a benefit in 1998, purchasing power rose by 1.6%. Naturally, it mainly increased for households who were no longer dependent on a social benefit in 1999. Purchasing power rose by less for households receiving a benefit in both years.
The increase in purchasing power for pensioners was on average 0.6%, about the same as in the preceding years, except 1998, when pensioners benefited from a tax deduction.

Map of Russia
Russia is located in the Northern hemisphere in Europe and Asia. It is the largest country in the world with an area of 17,075,400 km². Of other countries Lara has visited, Russia shares borders with Kazakhstan and China, as well as maritime borders with Japan, and the USA (Alaska).
Russian Levels in Tomb Raider Chronicles
Main article: Russia Section
The Base
During World War II a German U-Boat carrying the legendary Spear of Destiny sank somewhere in the North Atlantic. A Russian crime organization headed by Sergei Mikhailov is out to retrieve it, and towards that end they have bribed a captain of the navy into using his submarine. Lara is closely on their tail. Here she must infiltrate the Zapadnaya Litsa port and sneak on board a nuclear submarine. Underwater the excavation of the wreck is done using an armoured diving suit. The stages in Russia are of an average difficulty.
Lara in Siberia
In Lara Croft: Tomb Raider, Lara must make her way to Siberia to find the lost city. While in Siberia she has numerous modes of transportation including plane, boat, and Siberian Huskies. Lara also encounters a mysterious young girl with whom she converses in Russian and the girl appears to know alot about Lara's father, Richard.

I'm interested in Sklyanin Algebras or Artin-Shelter regular algebras of type A. These are generated in degree 1 by three variables x,y,z, and have three defining relations in degree 2, which you can get by multiplying the matrix $$M=\begin{pmatrix} cx & bz & ay \\ az & cy & bx \\ by & ax & cz\end{pmatrix}$$ either on the left or right by the row/column vector of variables. (For every triple of numbers $a$, $b$, $c$, excluding a finite set, you get one of these algebras.)
Such algebras $A$ contain a central regular element of degree $3$, let me call it $g$. It has the property that $A/gA$ is the twisted homogeneous coordinate ring of the scheme of point modules of $A$, which is the cubic curve defined by $\det M$. $$g=c(c^3-b^3)y^3+b(c^3-a^3)yxz+a(b^3-c^3)xyz+c(a^3-c^3)x^3$$
This central element $g$ seems somewhat mysterious. In the original paper by Artin-Shelter it was apparently found by a computer search, in the foundational paper by Artin-Tate-Van den Bergh, only its existence (and its properties) are proved.
My question is: is there a conceptual way to get this element $g$? Sorry, it's a little vague. Thanks for any insight into this matter.
share|improve this question
If translation by the point $\tau$ of the elliptic curve $E$ has infinite order, then the center of $A$ is $k[g]$. That's the only intrinsic description of $g$ I know. There might be more known about the two central elements in the Sklyanin algebra of GKdim 4. Paul Smith has some notes that might be useful there: math.washington.edu/~smith/Research/Skly-survey.pdf – Graham Leuschke Apr 25 '13 at 20:22

Fairy rings appear for apparently no reason at all on well-kept greens, causing anxiety in the green keeper and the players alike. They are caused by a fungus and are difficult to get rid of.
The appearance of some types of fairy rings (such as shown in the image above) do not necessarily affect the running of the bowls. But some types of fairy rings require closing the green while the condition receives treatment, or waiting for the problem to solve itself over time.
Fairy rings on bowling greens
To get an intelligent, scientific answer to the vexing question of what to do about fairy rings on a green, I referred to Dr Charles Louw's book named Lawn Bowls: Greens Management. Here is what he says:
One or more of about a dozen fungi that feed on decaying organic material can cause Fairy Rings.
Most of these fungi belong to the basidiomycetes group. They are normally
characterised by dark arc-shaped rings appearing in the spring or early summer with
or without a paler area inside the darker ring.
The fungus may grow deeply in soil with a dense, white threadlike network of mycelium. As the fairy ring fungus grows outward, it leaves behind older mycelium in the inner ring. These mycelia die, and as they decompose, they give off nitrogen, which gives the grass the dark green colour.
This proves that the active portion of the fairy ring is actually outside the ring that we see.
Symptomatically three types of Fairy Ring are recognised.
Type I Fairy Ring
This type of fairy ring causes the soil and thatch to become hydrophobic, killing the turf in patches, rings, or arcs. In areas affected by a Type I Fairy Ring, the thatch and soil are extremely dry and repel water.
Type II Fairy Ring
This type of fairy ring (as illustrated in the image above) appears as rings or arcs of turf that are
dark green and growing more quickly than the surrounding turf.
Type III Fairy Ring
These fairy rings are characterised by mushrooms or puffballs produced
in a ring or arc as per the photo here.
The type of symptom expressed by a particular Fairy Ring may change during the year according to weather conditions. Type III Fairy Ring symptoms are more prevalent during extended periods of wet weather. Type I and Type II Fairy Ring symptoms are most common during hot, dry weather in the summer.
Control and eradication
Control of Fairy Ring are very difficult. The only assured way of getting rid of Fairy Ring is to remove that portion of the turf, sterilise the soil, and replant. Some success has been achieved by applying a seaweed fertiliser with Fulvic acid plus a micro-organism monthly during the growing season.
Limited success has been achieved by aerating an area about 300 mm wide just outside the dark ring and to a depth of 200 mm. This area should be watered well with a wetting agent and a fungicide, for example, azoxystrobin (Heritage).

Title: These are not 'regular places': women and gender studies classrooms as heterotopias
Journal: Gender, Place and Culture.
This article questions the transformative potential of women and gender studies classrooms through a discussion of student experiences of privilege and oppression in these spaces. Using in-depth interviews with 22 undergraduate students from two contrasting Canadian universities, this article explores how women and gender studies classrooms function as heterotopias or 'other places' – sites that challenge 'regular' places outside of the academy. Critically analyzing student experiences illustrates to how the intersections of space/location, power, and identities inform notions of privilege and oppression within these classrooms. Analysis of the participants' reflections points to how it is through these 'other places' that students are able to recognize identities that were once unknown to them, become conscious of their embodiments via feelings of worry and discomfort, and question their sense of place in the classroom. It is because of these findings that this research functions as a call to instructors regarding the need to prioritize student experiences, so as to be able to critically reflect upon the social and academic significance of women and gender studies classrooms.

Empty space at the bottom of gVim windows
When using a window manager configured to ignore window size hints, gVim will fill the non-functional area with the GTK theme background color.
The solution is to adjust how much space gVim reserves at the bottom of the window. Take note that if you set it to zero, you won't be able to see the bottom horizontal scrollbar, if you have one. Put the following line in ~/.vimrc:
set guiheadroom=0

"^M"
There is a "^M" at the end of each line. This usually happens when you are editing a text file which was created in MS-DOS or Windows.
Solution: Replace all "^M" using the command:

4c46. α and β will resolve to an input, or a set of inputs, that trigger the execution path we're looking for.
While symbolic execution is much more precise than fuzzing (and other techniques), it is also much more computationally expensive. Symbolic execution is especially problematic when the program contains loops, where it suffers from the state explosion problem: in loops such as while (condition) the state may be forked indefinitely, and thus the symbolic execution algorithm would never explore the program past the loop.
Symbolic execution also scales poorly to large programs. For example kernels such as Linux are difficult to execute symbolically, as they depend on a lot of internal and external state and some of the code (e.g. the scheduler) will immediately lead to state explosion.
To solve the scalability issue, symbolic execution engines use various strategies: massively parallel execution and state merging (merging the constraints of two states into a single state) are two optimizations. Additionally, some engines, such as S2E, selectively execute only a subset of the code, switching between concrete and symbolic execution as the need arises.
Symbolic execution can also be combined with other analysis methods (e.g. fuzzing) through a technique that is known as concolic execution. Concolic execution involves performing symbolic and concrete execution in parallel, or (often) executing the program with concrete arguments up to a certain point, then continuing with symbolic execution.
Examples of symbolic execution engines include Angr, KLEE, Kite, Mayhem and S2E.
Tutorial: Symbolic Execution using Angr [2p]
First, install angr. See _URL_
Make sure you grab all the dependencies, as per the documentation:
sudo apt-get install python-dev libffi-dev build-essential virtualenvwrapper
Note that you need to install angr in a Python virtual environment. If you're on Debian/Ubuntu, make sure you have the virtualenvwrapper package installed. Also make sure that in all the terminals where you want to use angr, you run the following commands:
$ # replace the following with your favourite Python virtualenv directory
$ export WORKON_HOME=~/.environments
$ # replace the following with your virtualenvwrapper.sh location if needed
$ source /usr/share/virtualenvwrapper/virtualenvwrapper.sh
This setup is not persistent, so you will have to run it every time you open a new terminal.
Then, to create the angr virtual environment, run:
$ mkvirtualenv angr
This will create the new virtual environment and activate it. To install angr inside the virtual environment, run:
(angr) $ pip install angr
To activate the existing angr virtual environment in a new terminal, run:
$ workon angr
(angr) $ python my_angr_script.py
For more details, refer to the Python virtualenv guide.
If you get the following message when you try to run solve.py:
ImportError: cannot import name arm
Try applying the workaround from this GitHub issue: _URL_
Then let's go to the 0-tutorial folder, which contains level07 and level07.c. We also have an example solver script called solver.py. Let's take a look at it.
angr organizes binary analyses into projects. Creating a new angr project is as simple as:
b = angr.Project('./level07')
First, we want to generate the arguments that we will pass to level07. The arguments can be concrete (e.g. Python strings, integers, etc.) or symbolic. We're lazy, so let's pass the two arguments as symbolic variables. angr uses claripy as a solver engine, so we will instantiate the arguments using it:
arg1 = claripy.BVS('sym_arg', 8 * 11) # maximum 11 * 8 bits
arg2 = claripy.BVS('sym_arg', 8 * 44) # maximum 44 * 8 bits
where arg1 is a symbolic value (BVS) of 11 bytes, and arg2 is another symbolic value, of 44 bytes. Note that we are passing arg1 as a string, and decimal int numbers passed to level07 are at most 11 bytes in length.
At this point, claripy does not know that arg1 is a number represented as a string. All it sees is a symbolic argument, which may resolve to any binary data.
Next, we want to create an initial state to start from. angr uses SimuVEX to represent program state, which includes a low-level architecture-dependent representation of the binary we're analyzing. angr provides a factory object to generate our initial state:
st = b.factory.entry_state(args=['./level07', arg1, arg2])
st.libc.max_strtol_len = 11 # tweak
st will be our new state.
The st.libc.max_strtol_len tweak tells the atoi/strtol symbolic representation to resolve strings that are of at most 11 bytes length (the default is 10). See this GitHub issue for more details.
At this point we (the user) are making an implicit assumption about atoi, i.e. we know that our input will be passed through it. This normally requires some trial and error.
Now we will create what in angr terms is called a path group. A path group is an object that we can use to explore paths in our program. We will create our new path group pg starting from st:
pg = b.factory.path_group(st)
At this point we can instruct the symbolic execution engine to:
 - perform a single step – pg.step()
 - perform a number of steps – e.g. pg.run(n=20) to run at most 20 steps
 - run until all paths have been executed – pg.run()
 - explore until a solution has been found – e.g.
 - pg.explore(find=0x804846b) will try to find a path that leads to 0x804846b
 - pg.explore(find=lambda path : my_predicate(path))) will try to find a path that satisfies my_predicate
 - pg.explore(find=addr1, avoid=addr2) will try to find a path that leads to addr1 and avoid all paths that lead to addr2
We want to find a path where the string "WIN!\n" is printed to standard output. Thus we will do:
pg.explore(find=lambda p: "WIN" in p.state.posix.dumps(1))
This can be read as: explore looking for the path p for which the current state p.state contains the string "WIN" in its standard output (p.state.posix.dumps(1), where 1 is the file descriptor for stdout).
After execution is done, we can print pg, getting something such as:
pg =
This tells us that pg contains exactly 1 path which reached the end, 1 path left to explore and 1 path for which a solution was found. At this point we could further explore along the active path, but we don't need to do that.
For example pg.found and pg.deadended are lists of paths; pg.found[0] is the first path in found, and pg.found[0].state is the current state in that path. See the "Stash types" section in the path groups chapter of the angr documentation for more details on types of paths in a path group.
Given that we have a found path, let's look at the current state in this path:
s = pg.found[0].state
We can do a lot of things with s, including:
 - inspecting file descriptor streams, e.g. s.posix.dumps(n), where n is a file descriptor number
 - inspecting registers, e.g. s.regs.eax
 - inspecting memory, e.g. s.mem[0x7ffeff18]
 - using the solver (s.se) to concretize symbolic values
See Working with Data and Conventions for more details on how to inspect memory, registers, etc.
We want to concretize arg1 and arg2 and print them, i.e.:
print "arg1 = {} ".format(repr(s.se.any_str(arg1)))
print "arg2 = {} ".format(repr(s.se.any_str(arg2)))
What we do here is instruct the solver to give us the string representation of the first solution it finds from solving constraints, for each of arg1 and arg2. See Program states for more info on how s.se works.
The output of our concretization will be:
arg1 = '-_PHONE_'
Let's try these out:
segmentation fault
It may be that above so many NUL-bytes will not work properly under Bash. So you can replace that with a command such as the one below
$./level07 -_PHONE_ $(python -c 'print "A"*40 + "FLOW"')
segmentation fault
angr is a very complex framework for symbolic execution. So if you are trying to do something in particular and don't know how, arm yourself with patience, consult the documentation and, if nothing seems to work, ask the lab assistant.

How can I change delimiter (brace) size in cases environment (for piece-wise function)?
share|improve this question
You have to put something inside the cases environment to make it expand. Surely you can show the piece-wise function, otherwise it's difficult to assess what you're actually trying to do. – Werner Dec 17 '13 at 20:02
May be provide an image illustrating what you want? For example you can affect the vertical space between the cases with \\[]. – azetina Dec 17 '13 at 20:11
1 Answer 1
If the size of the brace (vertical and/or horizontal) are of prime concern, an alternative to the cases environment is given below. In this MWE, the stacked cases are composed of a \Vectorstack (stackengine package) in which the argument is set in math mode on equally spaced lines set about the math axis. The brace is produced by the scalerel package, and is merely a width-limited vertical scale of a glyph, in this case the left brace {.
Vertical height of brace matches target stack:
\[ f(x) =
\[ f(x) =
Vertical height of stack can be extended beyond stack height:
\[ f(x) =
Maximum horizontal width of brace set by optional parameter:
\[ f(x) =
\[ f(x) =
\[ f(x) =
enter image description here
This is just a demonstration of the ability to manipulate the brace. For a real problem, there may be other considerations... If the vertical separation between "cases" needs to be increased, \setstackgap{L}{length} prior to the stack can accomplish that, for example. See the package documentations for details. Your mileage may vary.

1404.03000 – General Principles of Contract Interpretation
PERB's interpretation of a collective bargaining agreement is guided by traditional rules of contract interpretation, including those set forth in the Civil Code. A provision of a memorandum of understanding stating that the MOU superseded all side letters except "grievance resolutions documents" was ambiguous. The parties' bargaining history showed the MOU did not supersede a prior written grievance settlement because: (1) during bargaining, the union told the employer that it considered the grievance settlement to be a "grievance resolution document;" and (2) the testimony of the employer's lead negotiator that he was unaware of the union's position when he agreed to the exception language was not credible. The employer's proffered interpretation that the exception was intended to apply only to future grievance resolutions is unreasonable because: (1) it is contrary to the plain meaning of "supersede;" and (2) it would leave the exception without effect.

If I include the Tikz flowchart directly into the main document, the font is emnbedded only once, but I don't want to compile it every time and sometimes I use other tools (e.g. Inkscape) to create figures (but they all use the same font).
In order to have a smaller pdf file (and because I think this behavior is strange) I would like to have each font included only once. I am aware of the tool pdfsizeopt, as described in the question How to create small PDF files for the Internet, but while it does decrease the file size, it does not help with the issue of fonts being included multiple times.

This is not specific to XeLaTeX, TikZ, or standalone; I've seen the same thing in LuaLaTeX when using the article class and a tabular environment to produce a letterhead, which I then include in letters with the wallpaper package. IIRC the same thing happened in pdfLaTeX too. In the case of letterhead it's not surprising, since that's where one tends to use titling caps and ligatures which don't appear in the body of a letter, so the subsets aren't the same. – Thérèse Jul 4 '13 at 22:32

I found no LaTeX-internal way to optimize that.You can use pdfsizeopt as an external tool to optimize the embedded fonts. It works great as long as the font names of the instances of the font are the same. It also uses subsetting, so that only the glyphs that you use are embedded and it converts fonts to a smaller format.
I suggest to disable the conversion of black-white-images to JBIG2 format for compatibility reasons and maybe the PNGOUT optimization for speed reasons. In every other aspect I always had full compatibility and good performance when optimizing PDF from PdfLaTeX and LuaTeX/ConTeXt.

Ver similar to…? Does LuaTeX have an equivalent to \pdfinclusioncopyfonts=1 (See) page 32 of the [pdftex manual][1] [1]: – WillAdams Jul 5 '13 at 19:31
_USER_ it has all the pdftex primitives I think. It has that one certainly (have not checked if it works in this case) – David Carlisle Jul 8 '13 at 16:32
_USER_ _USER_ Does XeLaTeX also support this command? Original question was about XeLaTeX and whenever I try using \pdfinclusioncopyfont I get the error message Undefined control sequence. – matth Jul 8 '13 at 20:21
_USER_ probably not. Luatex is based on the pdftex sources and is a pdf engine generating pdf so incorporates all the \pdf... primitives. xetex is based on classic dvi tex and pdf is generated by the dvipdfmx dvi driver, so an analogous question would be is there a \special that could control font loading in dvipdfmx (I don't know the answer). – David Carlisle Jul 8 '13 at 20:28
I'm not sure when, but pdfsizeopt has been dropped from Google Code "due to a complaint received under the U.S. Digital Millennium Copyright Act." :( is still available, and directions of use seem to now be separate/scattered on the Internet. – Werner Sep 20 '13 at 5:35
Unfortunately, XeTeX doesn't have a facility for parsing an imported graphic and remapping the fonts --- pdfTeX does afford this (and lualatex inherits it) and includes a command to enable doing so:
Try \pdfinclusioncopyfonts=0
From page 32 of the pdftex manual:
\pdfinclusioncopyfonts (integer)
share|improve this answer
Where should I put that command? No matter what I tried, I get an Undefined control sequence error. Would you mind creating a fully compilable MWE? – matth Jul 8 '13 at 20:16
use it w/ lualatex, not xelatex, per David Carlisle above. – WillAdams Jul 8 '13 at 22:07

Likelihood of a white Christmas in Northwest Colorado high
There are many reasons that people enjoy living on the Western Slope. Researchers at Colorado State University (CSU) just discovered another one the probability of a white Christmas is higher than anywhere else in the state.
Researchers claim that the La Nieather phenomena that is affecting most weather patterns around the country has little impact on Northwestern Colorado.
Nolan Doesken, assistant state climatologist and research associate with CSU's Department of Atmospheric Science, has found there is little correlation between La Nind the likelihood of fresh snow in the mountains and on the Western Slope. He based his prediction on weather records dating back to 1949.
"The current weather pattern is favorable for northern and central mountain snows a few days before Christmas so that there will be a good cover of white," said Doesken.
The La Nihenomenon makes it somewhat less probable that snow will cover parts of Colorado this year as it did in 1997, said Doesken. Therefore snow for Christmas 1999 is less likely on the Eastern Slope due to prevailing La Nionditions that have been in place since early summer 1998.
Doesken compiled a chart analyzing snow on the ground and fresh snow for Dec. 24 and 25 for 19 test locations. The chart is based on a long-term history of the areas under all conditions, from 1949 to 1998.
The closest test site to Craig was Steamboat Springs. Doesken believes that there is a 96 percent chance that Steamboat Springs will have at least an inch of fresh snow on the ground for Christmas. He also predicts a 44 percent chance of having at least half inch of snowfall on Dec. 24 or 25.
In the last two days, Craig has had 5 inches of snowfall, according to the National Weather Service.

Ethiopia is set to commence the second phase of its space strategic development roadmap, which involves the construction of satellite manufacturing, assembly, integration and testing (MAIT) facilities.
In a recent disclosure to Space in Africa, the General Director of the Ethiopian Space Science and Technology Institute (ESSTI), Dr Solomon Belay, hinted that the Ethiopian government has reached an agreement with French space company, ArianeGroup, to commence the construction of MAIT facilities in Addis Ababa in January 2020 with a completion timeline of 30 months.
Dr Belay did not reveal the terms of the deal with ArianeGroup and the cost of the project.
However, a statement released by Ethiopia's Ministry of Innovation and Technology notes the "support" of European Investment Bank in the project, and a tripartite agreement between the Bank, the Ethiopian government and ArianeGroup.
Space Engineering Research and Development Directorate (SERDD), a division under the ESSTI, has been designated with a leading role of managing the MAIT centre and maximizing its capacity in developing indigenous satellite systems and components.
According to the strategic plan and development roadmap obtained by Space in Africa, to help realise the mission stated under Aerospace Manufacturing, Assembly, Integration, and Test Facilities Development segment, SERDD may concentrate on the "design, development and manufacturing of highly accurate, precise, portable, easily maintainable, replaceable, and automated MAIT equipments that may not only be used for aerospace industry but also other manufacturing industries".
The other facilities currently under construction is a mechanical and electrical laboratory. The Directorate believes that having these laboratories will aid in the research and development of new technologies in the aerospace field.
The project, when completed and put into operation, will be of great help not only to Ethiopia but also to the East African space sector. Ethiopian engineers will be involved in the project. It is expected to create technology and knowledge transfer.
In Africa, only South Africa and Algeria have functional AIT facilities. Egypt recently commenced the construction of its AIT centre in collaboration with China. Nigeria is also looking to complete its AIT facilities since it began the project over 8 years ago.


No spontaneous second wind in muscle phosphofructokinase deficiency

Abstract
Objective: The spontaneous second wind in myophosphorylase deficiency (MD, McArdle's disease) represents a transition from low to a higher exercise capacity attributable to increased oxidation of blood-borne fuels, principally glucose and free fatty acids. Muscle phosphofructokinase deficiency (PFKD) blocks the metabolism of muscle glycogen and blood glucose. The authors inquired whether the additional restriction in glucose metabolism in PFKD prevents a spontaneous second wind. Methods: The authors compared the ability of 29 patients with MD and 5 patients with muscle PFKD to achieve a spontaneous second wind during continuous cycle exercise after an overnight fast. Patients cycled at a constant workload for 15 to 20 minutes (3 MD patients, 3 PFKD patients) and at variable workloads in which peak exercise capacity was determined at 6 to 8 minutes of exercise and again at 25 to 30 minutes of exercise (29 MD patients, 4 PFKD patients). Heart rate was monitored continuously, and perceived exertion (Borg scale) was recorded during each minute of exercise. Oxygen utilization and blood levels of lactate and ammonia were determined at rest and during peak workloads. Results: All variables in both patient groups were similar at 6 to 8 minutes of exercise. Thereafter exercise responses diverged. Each MD patient developed a second wind with a decrease in heart rate and perceived exertion and an increase in work and oxidative capacity. In contrast, no PFKD patient developed a spontaneous second wind. Conclusions: Patients with muscle phosphofructokinase deficiency are unable to achieve a spontaneous second wind under conditions that consistently produce one in patients with McArdle's disease. The authors conclude that the ability to metabolize blood glucose is critical to the development of a typical spontaneous second wind.

text: The feasibility of performing quantitative analysis with short segments of bandpass-filtered Fourier transform infrared (FT-IR) interferograms is demonstrated. The protocol developed in this work addresses four limitations that hinder the use of FT-IR spectroscopy in nonlaboratory applications: (1) the need for a rugged, low-cost, and reliable spectrometer, (2) the lack of representative background spectra for use in acquiring absorbance spectra of the target analyte, (3) the presence of overlapping spectral bands that interfere with the analyte determination, and (4) the difficulty in obtaining useful information from data collected near the limit of detection. In this work, spectral information pertaining to a specific analyte band of interest is isolated directly from a short interferogram segment by the application of narrow-bandpass digital filters. When processed in this way, the filtered interferogram segments contain compound-specific information that can be utilized for quantitative analysis. Successful use of a univariate calibration procedure with filtered interferogram data of benzene and nitrobenzene of varying concentrations is demonstrated. Calibrations based on filtered interferogram segment magnitudes vs concentration yield models with values of R2 in excess of 99%. These results are obtained without the use of a separate background or reference interferogram. This interferogram-based analysis is shown to perform analogously to a conventional spectral-based analysis, with the interferogram method being more efficient in terms of data collection and computational requirements.

Abstract：The Licklider transmission protocol(LTP) is a point-to-point protocol that is mainly used to transmit data between adjacent nodes in space networks. LTP achieves reliability by return acknowledgements and retransmissions. Typical applications have long distances between network nodes which result in large transmission delays. This delay is further multiplied by the acknowledgement and retransmission processes. Thus, the number of round trips(QoRT) needed to successfully transmit an LTP block needs to be investigated. This paper presents an analytical evaluation of the QoRT that gives the distribution function, mean and variance of the QoRT. The results also give more concise upper bounds, lower bounds and approximate means. Simulations verify the theoretical results.
