Voice Internet Protocol (VoIP) Telephony refers to the technology used for making telephone calls over the Internet. The two major technologies used to implement VoIP telephony are Asterisk and OpenSER. This article by Flavio E. Goncalves compares Asterisk and OpenSER topic by topic and shows the differences between them.
If you work with IP telephony, it's quite possible that you have not heard about OpenSER, but certainly you must have heard about Asterisk. Well, I love a polemic headline and I have seen this question asked in the forums many times. So, I will dare to compare these two very popular softwares dedicated to the VoIP market. The idea here is not to show you which one is the best, but mainly how they are different from each other. Below is a comparison topic by topic.
Asterisk is a Back to Back User Agent (B2BUA), while OpenSER is a Session Initiation Protocol (SIP) Proxy. This makes all the difference between them. The SIP proxy architecture is faster than a B2BUA because it deals only with signaling. On the other hand, the B2BUA architecture, even being slower, handles the media and it is capable of several services not available in a SIP proxy such as Codec Translation (that is G729<->G.711), Protocol Translation (SIP<->H323), and services related to media such as IVR, Queuing, Text to Speech, and Voice Recognition.
OpenSER deals a lot better with NAT traversal then Asterisk. You can send the media from your customer directly to the provider using OpenSER in most cases (non-symmetric NAT). Manipulating directly the SIP protocol allows you to handle special cases, such as, when you have two customers behind the same NAT device and want to send the media directly between them.
OpenSER has specific load balancing algorithms with hash. So it can load balance by the "ruri", "username", "call-id", and some other properties. It can use redirected messages consuming very few resources from the load balancer machine. Failover is part of the solution, things you won't find on Asterisk, but are complementary.
Low Level Access to SIP Header and Transactions
OpenSER gives you low level access to the protocol. You can handle all the requests and responses. So it is possible, most times, to translate between two incompatible versions of SIP, handling directly the SIP headers, requests, and responses. This is an important feature when you have SIP implementations from different manufacturers, which can be incompatible between each other.
Integration with Radius, Diameter, and LDAP
OpenSER has built-in integration with LDAP, Radius, and Diameter. While this is also possible with Asterisk, the implementation on OpenSER is developed in C, integrated as a module, and is part of the OpenSER distribution (no perl, no python, no third-party modules).
Carrier Class Routing
The module CARRIERROUTE implements sophisticated algorithms to route calls to the PSTN. Some times VoIP providers have tables with more then 40.000 routes. In this case, you will absolutely need a specific routing module capable of failback, blacklists, and some other features specific to VoIP providers.
OpenSER is a SIP Proxy and is not capable of any media related services. So it is not possible to create, using OpenSER, systems such as VoiceMail, IVR, TTS, and Voice Recognition. However, it is possible to integrate any of these services to the platform using a separate Media Server such as Asterisk, Yate, and FreeSwitch. This is by design, and it is the way the SIP protocol is defined in the standards (RFC3261).
Connectivity to the PSTN
OpenSER always need a SIP gateway to connect to the PSTN. There is no possibility to install telephony cards in the server. In several cases, Asterisk is used as the PSTN gateway for OpenSER.
I love this discussion, because Asterisk and OpenSER completes one another. OpenSER provides rock solid SIP services to VoIP providers, it is capable to handle large volumes of calls, to load balance SIP, to solve advanced NAT scenarios, and to deal with SIP signaling as no other. Asterisk is a B2BUA, very strong in the PBX market. It is simpler to configure and can handle low to medium volumes. Asterisk can be used as a "single box does it all", while OpenSER requires all the architectural components of SIP to work. OpenSER is a "hit" in the VoIP provider market and in Universities. Asterisk PBX is a success in the IP PBX market, and it is getting a piece of the small to medium VoIP providers. Usually you start using OpenSER when you have some special need, such as load balancing or when you have large volumes such as more than a thousand registered users. Choose wisely!

Flavio E. Goncalves was born in 1966 in Minas Gerais, Brazil. Having always had a strong interest in computers, he got his first personal computer in 1983 and since then it has been almost an addiction. He received his degree in Engineering in 1989 with focus in computer aided design and computer aided manufacturing. He is also CEO of V.Office Networks in Brazil, a consulting company dedicated to the areas of Networks, Security, Telecom, and Operating Systems and a training center since its foundation in 1996. Since 1993, he has participated in a series of certification programs having being certificated as Novell MCNE/MCNI, Microsoft MCSE/MCT, Cisco CCSP/CCNP/CCDP, Asterisk dCAP, and some other.
He started writing about open-source software because he thinks the way certification programs were organized in the past was very good to help learners. Some books today are written by strictly technical people, who, sometimes, do not have a clear idea on how people learn. He tried to use his 15-year experience as instructor to help people learn open-source telephony software. His experience with networks, protocol analyzers, and IP telephony, combined with his teaching skills, gave him an edge to write this book. This is the second book he has written; the first one was The Configuration Guide for Asterisk PBX. As the CEO of V.Office, Flavio E. Goncalves balances his time between family, work, and fun. He is the father of two children and lives in Florianopolis, Brazil, in his opinion one of the most beautiful places in the world. He dedicates his free time to water sports such as surfing and sailing.

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

Description - With 350,000 acres and over 500 miles of trails stretching over two-thirds the length of Vermont, the Green Mountain National Forest offers endless opportunities for people of all ages and abilities to get into the great outdoors all year long. From rugged mountaintops to secluded streams, you'll discover the ideal place for every activity from birding, berry picking, canoeing to cross-country skiing, mountain biking and snowmobiling. The legendary Appalachian Trail and Long Trail run through the Forest with a network of well-maintained shelters spaced a day's hike apart.
The Marsh-Billings-Rockefeller National Historic Park is named for George Perkins Marsh, one of the nation's first global environmental thinkers, who grew up on the property, and for Frederick Billings, an early conservationist who established a progressive dairy farm and professionally managed forest on the former Marsh farm. Frederick Billings' granddaughter, Mary French Rockefeller, and her husband, conservationist Laurance S. Rockefeller, sustained Billings's mindful practices in forestry and farming on the property over the latter half of the 20th century.
- The Green Mountain is Vermont's National Forest. Hills and mountains, ponds and brooks, it is a recreation jewel. With over 350,000 acres, it represents 50% of all public lands in Vermont. The Forest is among the region's leading attractions for outdoor enthusiasts, yet at the same time, a carefully supervised supplier of timber, wildlife habitat and clean water.
Marsh-Billings-Rockefeller National Historical Park was created in 1992, when the Rockefellers gifted the estate's residential and forest lands to the people of the United States. Today, the Park interprets the history of conservation with tours of the Marsh-Billings-Rockefeller mansion and the surrounding 550-acre forest. Working in partnership, Marsh-Billings-Rockefeller National Historical Park and the Billings Farm & Museum present historic and contemporary examples of conservation stewardship and explain the lives and contributions of George Perkins Marsh, Frederick Billings and his descendants, and Mary and Laurance S. Rockefeller.
Recreation - The Green Mountain National Forest is a four-season (some say six with mud and Black Fly season) recreation experience. The most popular season is autumn when the mountains are ablaze with color. Summer is popular for camping, hiking, backpacking, fishing and canoeing. Winter brings out skiers (both downhill and cross-country), snowboarders, snowmobilers, and snowshoe enthusiasts. In spring, the Forest bursts forth from the grip of winter with emerging leaves on the trees, migrating birds, and blooming wildflowers that are visible along many of the Forest trails.
Visitors to Marsh-Billing-Rockefeller National Historical Park can explore an extensive network of carriage roads and trails through one of the nation's oldest continuously managed forests, established by Frederick Billings in the 1880's on the deforested flanks of Mount Tom. Guided tours and public programs are offered on the history of the forest and larger estate landscape with a special focus on conservation history and the stewardship of working landscapes and countryside. Also, tours of the 19th century Marsh-Billings-Rockefeller mansion feature landscape paintings by Thomas Cole, Albert Bierstadt and Asher B. Durand, as well as artists and photographers who in their day helped to shape popular perceptions of the environment. Hiking, nature study and cross-country skiing are recreational activities available to visitors.
Climate - Vermont's climate varies somewhat depending on region. Generally, the state experiences mild summers with temperatures rarely reaching 90 degrees F. Often summer lows will dip to 50 degrees and by late August temperatures begin to cool. The mountainous regions of the state have seen snow fall in every month, so be prepared for cooler temperatures if staying in those areas.
Winters can be harsh and long in this northern state. Snow is likely to fall anytime between September and April. Humidity makes winter weather seem bitter and usually a few weeks during the winter see night time temperature below zero. The average winter temperature is 20 degrees F with highs reaching into the forties on warm days.
The Green Mountain National Forest is divided into two separate sections. One section is in central Vermont and the other in southern Vermont. The Forest Headquarters is located in Rutland, with Forest offices also in Manchester, Rochester and Middlebury.
The Marsh-Billings-Rockefeller National Historical Park is located on Vermont Route 12, 1/2 mile north of the Woodstock Village Green. The park shares a parking lot and Visitor Center with the Billings Farm & Museum. From Boston and points East: take I-93 North to I-89 North. Follow I-89 through Lebanon, NH into Vermont; take Exit 1/Route 4 West through Quechee and Taftsville to Woodstock (10 miles from Exit 1). From Burlington and points North: take I-89 South to Exit 1/Route 4 West and continue through Quechee and Taftsville to Woodstock (10 miles from Exit 1).

Cystectomy is an oral surgical procedure for removing the periapical lesions of teeth or abscesses, granuloma, and various cysts. The mentioned formations or changes are visible at the root of the tooth and are most frequently noticed with a panoramic x-ray when a patient comes to a dentist because of great pain and swelling.
Changes that demand a cystectomy are infective changes or abscess and granuloma, post-traumatic changes or traumatic cysts and various abnormalities or developmental cysts.
What are oral cysts and how do they occur?
Oral cysts are cavities covered with tissue and can appear in the jaw or the soft tissue (for example in the cheeks). Oral cysts occur because of a constant infection, which occurs on the top of the root.
The infected teeth are most frequently due to poor oral hygiene or not treating cavities on time.
Recently, genetic heritage has also been mention regarding oral cysts along with other various hereditary syndromes.
What are the symptoms of oral cysts?
It is very important to emphasize that the patient feels the first symptoms when the cyst is already in an acute condition and the pain begins. The symptoms of oral cysts are:
– Changes in the color of the tooth
– A large cavity which has not been treated
– A bump on the bone (jaw) above the tooth
– Pain, swelling, redness around the tooth
How to treat an oral cyst?
If one of the stated changes was diagnosed, it is necessary to remove the change as soon as possible so it does not grow and spread to neighbouring teeth. Without treatment, the tooth structure could weaken, damage healthy teeth, spread to the sinuses and nose and cause great infections on the face.
Cystectomy is performed with local anesthesia that means the procedure is completely painless for the patient. The oral surgeon, during the procedure, completely removes the cyst, shortens the top of the root and closes the root canal. If the cyst has spread to a larger part of the root, then it is necessary to remove the tooth and remove the cyst. Stitches are removed a week after the procedure.
- After surgery, it is necessary to put a cold compress on the place of procedure to reduce swelling
- Taking painkillers recommended by a dentist in the case of pain
- Taking antibiotics to shorten the postoperative recovery
- After 7 days, stitches are removed, and all this time it is necessary to maintain maximum oral hygiene and brush around the wound with gentle movements to remove plaque
- Gargling with sage tea, salt water or antiseptic
- In the case of mild bleeding from the stitches a damp bag of tea can be applied on them (black tea is recommended)
- After the procedure, it is preferable to eat liquid food, hot drinks and hot food should be avoided
- It is recommended to avoid smoking immediately after the procedure
- It is recommended to avoid alcohol consumption

Fiber-Matrix Displacement during the Compressive Phase of Shock Loading
ARMY BALLISTIC RESEARCH LAB ABERDEEN PROVING GROUND MD
Pagination or Media Count:
Electromagnetic-gage type measurements were performed to determine fiber wire-matrix displacement during the compressive phase of shock loading. Fiber diameter and shock impedance were the variables investigated. The relative displacement was found to increase with the fiber diameter, but data for each fiber material could be well represented by a single curve if fiber diameter was used as the unit of relative displacement and shock transit time through the fiber diameter was used as the unit of time. Fibers attained the matrix velocity after a maximum, normalized relative displacement which varied linearly as the three-halves power of the shock impedance.

The ships were designed by Vickers-Armstrong shipyards in the 1950s for the Venezuela naval forces. The design has been identified as a derivative of the Batch 3 Battle-class destroyers built for the United Kingdom and Australia, according to information released by the International Naval Research Organization and several independent researchers in 2006. They were to form part of a fleet that included a 25,000 ton aircraft carrier and a Tiger-class cruiser.
The fleet arrangement for 30/04/1949 covers:
- 1 (25,000-ton) aircraft carrier (conceptual engineering)
- 1 (8,000-ton) cruiser (detailed engineering)
- 3 Nueva Esparta-class destroyers (built)
- 6 Almirante Clemente-class destroyers (built)
- 4 submarines (1 used from US Navy)
- 12 patrol boats (detailed engineering)
- 2 minesweepers (basic engineering)
- 1 marine assault ship (built)
The names assigned to these ships were associated with states in Venezuela.
- Nueva Esparta refers to bravery and loyalty.
- Zulia to remember the Battle of Lake Maracaibo in the Venezuelan War of Independence and the huge contribution of this state to that conflict.
- Aragua because this state is the military heart of Venezuela, and as homage to the La Victoria battle remembered on "Youth Day".

Laser Cooled Atomic Physics, while based on physics experiments preformed in the 1940s,
is a very young field of research dating from about 1980. Three physics Nobel prizes
have been awarded for this field since that date, demonstrating the excitement that the
new results have generated in the community of physicists.
The Fundamental Physics research program presently supports four flight experiments and
nineteen ground-based experiments in LCAP. The four flight experiments are described
in the write-ups for PARCS, RACE, BEC, and SMW-G. The first flight for PARCS is expected
to occur in 2003. PARCS will demonstrate the technology development of the ultra-stable
clock, plus the experiment will provide tests of Gravitation and Relativity Physics.
Other experiments in this field will examine the standard model of physics, providing
tests of ideas such as time reversal symmetry (Can experiments run backward as well as
forward in time?).

Roughly 80 percent of injecting drug users in rural Puerto Rico have hepatitis C, and about 7 percent have HIV, a UNL sociologist has found. Kirk Dombrowski is using his expertise in studying how people form social connections to explore how drug users' social lives influence disease spread.
Ultimately, this research should identify effective prevention strategies for rural areas. This work is part of UNL's Minority Health Disparities Initiative, which targets understudied health issues.
"The bulk of the interventions used to prevent the spread of HIV, for example, are designed for urban areas," said Dombrowski, who heads the initiative. "Puerto Rico makes a nice test case for other rural areas, especially when we look at Native American populations, which have much higher hepatitis C rates than most."
Dombrowski and collaborators are surveying Puerto Rican drug users to understand how they form social relationships and communicate information. Computers help analyze how social networks evolve over time in relation to risky behavior. This information will help researchers identify effective interventions. A $2.9 million, five-year grant from the National Institutes of Health's National Institute for Drug Abuse supports this work.
"Social network analysis is an innovative method that we feel could go a long way toward helping us understand what is and is not working."
In a different setting, Dombrowski is using similar social network analysis to study suicide prevention strategies in Alaskan native populations, where suicide rates, like those in Midwestern native populations, are high. He collaborates with University of Massachusetts Amherst colleagues on this work funded by NIH's Institute for Mental Health.
"Social network analysis is an innovative method that we feel could go a long way toward helping us understand what is and is not working," Dombrowski said.
UNL's Minority Health Disparities Initiative also is training the next generation to use social network analysis to solve minority health issues. In summer 2015, it hosted 10 undergraduates from around the nation who studied and worked with UNL research mentors. This new program, funded by a National Science Foundation Research Experience for Undergraduates grant, is the nation's only REU to explore minority health disparities.

of your movement.
5. Speed: Being too slow pulling up or not coordinating your reach to be on point can lead you to miss the hold you are aiming for and the deadpoint.
6. Lastly, if you feel you are at the end of your session, or you feel you are tired, it's better not to try practicing the deadpoint, as you would be more prone to falling and injuring yourself.
Helpful Deadpoint Tutorials on YouTube
To help you combine theory with practice, we found some great tutorial videos on YouTubethat showcase the deadpoint technique. Seeing the technique applied in the field will definitely make it easier to figure out its body mechanics.
Neil Grasham's masterclass gives the key components to executing the deadpoint technique successfully:
This tutorial goes over technique tips for deadpoint practice and some common mistakes to avoid:

Wrapping Things Up: Final Things to Remember for How to Deadpoint
The deadpoint, not only has a cool name, but it is also a cool and incredibly useful climbing technique to master. This dynamic climbing movement combines static elements to help you reach challenging holds that are further away.
Achieving that moment of weightlessness after you extend your body will give you just enough time to grab a hold that may not be so good.
Let's go over the key points on perfecting your deadpoint technique and improving your climbing:
- Really focus on the target hold, for increased precision.
- Align your center of gravity with the hold you are reaching for.
- Bring your hips down to gain just enough momentum. The hips should direct the movement.
- Fully extend your body while you reach, keeping your arms and legs as straight as you can.
- Coordinate all the actions that make up the deadpoint: Pushing with the feet, pulling with one hand, and reaching with the other hand.
- Keep your core engaged and maintain body tension for more control in the movement.
- Keep your feet and hand that are on the wall as solid and stable as you can.
- Commit to the movement completely. If you have doubts while you shoot upwards, there's more chance of falling.
- Don't practice the deadpoint if you feel you're too tired.
Most importantly, practice! Improving your climbing takes work. Deadpoint practice with different holds, at different distances, will help you learn how to handle your body weight and improve your balance.

Shipmate Flagchart : _URL_
adopted 2 Oct 1962; design: Kl. Sierksma.
According to "Wie, Wat, Waar? 1940", an annual published by the
Rotterdamsch Nieuwsblad in Nov. 1939, the flag of Den Helder was: white,
with in the center the full municipal arms.
Jarig Bakker, 26 May 2005
Arms: gules three chevrons, surmounted by a crown, all or.
Julianadorp is a small village at the southern end of Den Helder municipality, Noord-Holland province; it was founded in 1909, the year Queen Juliana was born. Huisduinen is a base of the Dutch navy, just west of Den Helder city.
The forgotten flag of Julianadorp.
A friend recently sent the design of the flag of Julianadorp to the webmaster of that site. They were quite surprised to see the date of 1936 on the design. No Julianadorper ever knew about this design, dug out from the municipal archives of Den Helder.
The flags of Julianadorp and Huisduinen have probably been derived from the arms of Den Helder, based on the arms of the Egmond family (yellow and red), the former owners of the Lordship of Huisduinen. These colors were also used for the flag of Den Helder, adopted in 1962.
The flags of both villages are divided in three main stripes, of which the middle one is itself divided in seven stripes, alternating red and yellow. The difference between the flag: for Julianadorp the top and bottom stripes are green (for the Koegras-polder), while for Huisduinen they are blue (for the Sea).
In 1984 the organisers of the celebrations of 75 years of Julianadorp's existence had no idea that this design existed, otherwise the village would have been totally covered by seas of flags. It is expected that this will happen in 2009, when the village will tally a century.

Jarig Bakker, 11 Aug 2005
The flags of Julianadorp and Huisduinen were almost certainly derived from the arms of Den Helder, as on the Julianadorp website is part of the original design sheet, with the caption: "Ontwerpen - Vlag van Huisduinen en Vlag van Julianadorp (in verband met het gemeente-wapen): "Designs - Flag of Huisduinen and Flag of Julianadorp (in connection with the municipal-arms).
In the narrow space below that text was added the addition "en in
verband met de geographische ": "and
in connection with the geographical..."
(This would probably be readable on the full scan, but here the head and the part for Julianadorp have been brought together in one image, without regards for that extra bit of information.)
Further information given is given on the web page, telling us that:
"De "vergeten" vlag van Julianadorp is ontworpen door dhr. Sierksma uit Groningen, deskundige op het gebied van de banistiek(vlaggenkunde). Hij heeft gelijkertijd ook een gemeentevlag en een vlag van Huisduinen ontworpen. De gemeentevlag is afgeleid van de vlag van de Egmonds, de vroegere eigenaar van heerlijkheid Huisduinen, met toevoeging van marine-elementen. Het ontwerp van de gemeentevlag is in 1962 officieel goedgekeurd door de gemeenteraad.":
"The "forgotten" flag of Julianadorp was design by dhr. Sierksma from Groningen, expert in the field of banistics (flag science). Simultaneously he also designed a municipal flag and a flag for Huisduinen. The municipal flag is dereived from the flag of the Egmonds, the previous owner of the seigniory, with addition of navy elements. The design of the municipal flag was officially approved by the municipal council in 1962."
"De vlag van Huisduinen en de vlag van Julianadorp zijn waarschijnlijk van dat ontwerp afgeleid. De vlaggen van beide dorpen zijn verdeeld in drie hoofdbanen, waarbij de middelste baan nog weer bestaat uit 7 smalle banen, afwisselend rood en geel. Het verschil tussen de dorpsvlaggen is de kleur van de bovenste en onderste baan. Deze banen zijn bij de Julianadorper vlag groen (van Het Koegras) en bij de vlag van Huisduinen blauw (van de Zee).":
"The flag of Huisduinen and the flag of Julianadorp probably are derived from that design. The flags of both villages are divided in three main stripes, whereby the middle stripe exists of again 5 narrower stripes, alternating red and yellow. De difference between the village flags is in the colour of the upper and lower stripe. These stripes are green in the Julianadorp flag (for Het Koegras) and blue for the flag of Huisduinen (for the Sea)."
"Het Koegras" is the name of the polder Julianadorp is situated in.
The "expert" is of course Klaas Sierksma, and hence it should come as
no surprise that the design is a full construction sheet, giving the overall
lengte = 1 1/2 x breedte, as well as the ratio of the stripes: 13/40, 1/20, 1/20, 1/20, 1/20, 1/20, 1/20, 1/20, 13/40.
Now, the bad news is: There's no way to simplify this ratio, so it's never going to fit a height of 216 pixels, though we could slightly improve the approximation.
The good news is: all information the construction sheet giffers need is right here. This flag too could be fully specified which such a beautiful image.
Note: The text doesn't mention the design ever being adopted. Considering
that at the time Sierksma's design for the municipal flag had been ignored
(rejected?), it could well be that the same happened to the village flags.

Mr Langshaw's Square Piano
Mr Langshaw's Square Piano
A clue inside a neglected square piano made in 1807, leads Madeline Goold on a quest to uncover the identities of the people who had owned and played it.
This biography of a now almost-forgotten instrument, which once held pride of place in drawing-rooms throughout Britain and its Empire, is a journey through two centuries of musical lives.
The author travels back in time and enters the musical world of Georgian England to meet the people who built and played the square piano that she found two hundred years later.
M.Clementi, Sonata Op.25, No. 5, First Movement (1790)
Javascript and Flash are required to play the recordings
She discovers that the original owner was a north-country musician, struggling to make a living and educate his children in the early years of the Industrial Revolution; Mr. Langshaw's Square Piano - (ISBN _PHONE_, Hardcover, Corvo Books, £13.99) traces the story of his square piano and sets it and Mr. Langshaw and his remarkable family, against the broader musical and social history of their time.
"It really carries the reader along and brings history alive. Great."
"…a tale that really draws the reader in…"
In his youth John Langshaw met and studied with some of the most celebrated musicians in Georgian London. He returned to his home town in the north of England with first-hand knowledge of the square piano, a new keyboard instrument that was taking the capital by storm, and he spent the next fifty years teaching music and distributing pianos on behalf of John Broadwood, the most successful English piano maker of the day.
Mr. Langshaw brought music to a part of the country where no one before him could even play Handel's Lessons, let alone teach them; in doing so he also brought the social change that accompanied the piano.

Square Piano
Square pianos, sometimes called box or table pianos, are not square but oblong. They were the earliest pianos and for sixty years from the time of their first appearance in London in 1768 they dominated the piano market.
Small and elegant, they reflected the finest furniture of the period. They had little leather hammers that struck rather than plucked the strings as in so many other keyboard instrument of the time.
What was really novel was that they could be played soft and loud, piano e forte. The square piano became a link between the keyboard instruments of the eighteenth century and the modern piano and bridged the time when only the very wealthy could afford a keyboard instrument to the mass production of the mid-nineteenth century.

Cape and Islands remain at high risk of drought, fires
State panel says lack of rainfall, higher than normal temperatures have lead to worst conditions since 2016
The state's Drought Management Task Force is recommending that the Cape's drought level remain classified as "significant," citing the region's worst drought conditions in four years.
The recommendation came during a meeting of the task force on Wednesday. A final decision on the region's classification will be made by the secretary of the Executive Office of Energy and Environmental Affairs.
The effects of the drought are starting to take hold on the Cape and Islands, including crop losses for cranberry growers and an increased risk of wildfires.
With precipitation levels being so low and the risk of fires so high on the Cape, drought conditions remain severe in the region, said Vandana Rao, executive director of the Massachusetts Water Resources Commission.
"We will keep a close watch this month," she said.
Several months of limited rainfall and higher than normal temperatures during the summer have brought about the Cape's worst drought conditions since 2016, Rao said.
The cranberry industry is having problems obtaining the water needed to harvest its crop and protect it against frost, Brian Wick, executive director of Cape Cod Cranberry Growers Association, said at the meeting. He said he has talked to two growers who lost their crops because they didn't have the water to protect the cranberry crops from frost.
The lowest temperature that cranberries can safely withstand is 23 degrees, according to information on the association's website.
In order to protect the fruit from frost damage, growers run an irrigation system that coats the fruit with a blanket of water. As the sprayed water coats the plants and berries, they begin to freeze. The physical process of water turning to ice releases heat that warms the plants.
"Protecting for frost is an issue, let alone flooding for crops," Wick said.
Hotze Wijnja, an environmental chemist at the Massachusetts Department of Agricultural Resources, said while other crops in the season are winding down and water is not as critical, the fall harvesting of cranberries is unique.
With dryer conditions due to the drought, the state is seeing a higher risk of wildfires, said Dave Celino, chief fire warden for the state Department of Conservation and Recreation.
In the last nine days, he said, there have been 52 fires across the state. Last week, there were 15 active fires due to drought, Celino said.
Due to the risk, the fire tower network has been extended and is up and running, Celino said. Many of the wildfires have been deep-burning, multiday operations, putting a strain on the local fire departments and other resources, he said.
The biggest area of concern is in Southeastern Massachusetts, including the Cape and Islands, Celino said. The Cape and Martha's Vineyard are creeping up in the fire danger index, entering a more severe drought classification, where there is an increased chance of wildfire occurrence.
"All of these fires are human-caused," Celino said. "It is hard to determine the exact cause but a lot of them are abandoned campfires.""
Nantucket does not have an open burning season this fall, and the town of Brewster has put a moratorium on outdoor fires, Celino said.
The task force bases its recommendations on six indicators: precipitation, stream flow, groundwater, lakes/impoundments, crop moisture and fire danger.
The precipitation indicator for the Cape is currently at Level 4, the most intense level that indicates exceptional drought. The indicators for crop moisture place the Cape at Level 2, which is severe drought, while the region is at a Level 3 risk of fire, indicating extreme drought conditions.
Groundwater levels on the Cape are normal, Rao said. However, she said levels are slowly deteriorating and should be watched, she said.
On Nantucket and Martha's Vineyard, the precipitation indicator is at Level 3, signifying extreme drought conditions. The indicators for crop moisture index and fire risk are both at Level 2.
It is unclear if rain will give the Cape and Islands any relief in the coming weeks, Nicole Belk of the National Weather Service said at Wednesday's meeting. There are a few scattered storms predicted, but she doesn't expect them to linger.
It is also uncertain whether Southeastern Massachusetts will get the remnants of Hurricane Delta, which is set to make landfall in the Gulf Coast states on Friday.

Rendering Saturn's Rings
It took me a while to figure out how to do this realistically in
Imagine. Similar techniques will probably work in other
rendering programs. Key steps are:
- Create a 1-dimensional transparency map. I obtained the raw
numerical data for mine from Bjorn Jonsson's planetary rendering
site, and digested it using an IDL routine to create a map that
would have correct geometry when wrapped with spherical
geometry around an axis located a pre-determined distance (I chose 2
Saturn radii) above the ring plane. The rendering of the rings here
was done using a 1 x 12,000 pixel maskbecause it's one dimensional
it can be very high resolution without using much memory. The nature
of spherical mapping means that only about 1/4 of those pixels can be
used for the actual ringsthe rest are blank.
Here is my 1 x 12,000 pixel transparency
mask, in.BMP formatdownload using "Save Link As".
- Create a plane larger than Saturn's rings, and center the texture
axis the predetermined distance above the center of the plane. Apply
the mask as a transparency mask, with spherical mapping around an
axis perpendicular to the ring plane.
- That's all that's required for the lit side of the ringsif the
ring color is something light, both the rings and their shadow on the
planet will look right. There might be a problem with the rings being
too dark when the sun is a small angle above themfixing this
requires some of the techniques required for the dark side of the
- The dark side is more complex because, like most rendering
programs, Imagine can't handle the diffuse scattering that
illuminates the dark side of the rings. A different model is needed,
that in addition to the transparency map has a brightness map, with
similar values and identical projection to the transparency map, but
set to zero where the rings are completely transparent, where the
transparency map's value is 255. Here is
my 1 x 12,000 pixel dark-side brightness mask, in.BMP formatdownload using "Save Link As".
- Because the dark side of the rings has a brightness map, it will
glow in the dark where Saturn's shadow crosses it, and we don't want
that. My solution is to use the Imagine slice function to
cut out the part of the ring that's in shadow (using a cylindrical
slicer), and color that part black (while maintaining the transparency
map, so the dark ring will still block light from the planet where it's thick).
The resulting ring model will only work for a single sun angle, but
I haven't yet found a better solution.
- The same "artificial shadow" will work on the lit side of the
rings, and allows addition of extra brightness to the lit rings to
make them brighter when the sun angle is low.

[N] 2007 Misleading interpretations of \\\\\\\"gastroliths\\\\\\\"
Wings, O. 2007. A review of gastrolith function with implications for fossil vertebrates and a revised classification. Acta Palaeontologica Polonica 52(1):1-16.
ABSTRACT: Misleading interpretations of \\\\\\\"gastroliths\\\\\\\" in fossil taxa have complicated the use of this term in palaeontology. This paper reviews the definitions and ascribed functions of gastroliths. According to the suggested definition, gastroliths are hard objects within the digestive tract of animals-without specification of the mechanisms that are responsible for their accumulation.
To further improve definitions, the origin-based terms \\\\\\\"bio-gastrolith\\\\\\\", \\\\\\\"patho-gastrolith\\\\\\\", and \\\\\\\"geo-gastrolith\\\\\\\" are introduced. The term \\\\\\\"exolith\\\\\\\" is introduced for isolated clasts with a possible history as geo-gastroliths. Hypotheses about the function of stomach stones in fossil and extant taxa are reviewed, discussed and supplemented with new research.
Trituration and mixing of foodstuff are the generally accepted functions of gastroliths in many vertebrates, including birds. In contrast, ballast provided by swallowed stones is considered to be of limited importance for buoyancy in aquatic animals. Other functional hypotheses include mineral supply and storage, stomach cleaning, maintenance of a beneficial microbial gut flora, destruction of parasites and alleviation of hunger.
Accidental ingestion of sediment, either by being mistaken for prey, by being attached to it, during playing or due to pathological behaviour, is considered to be common. Different functions may overlap in various taxa.

Virtual reality programming of a manufacturing cell
The main functionality of the module is to utilize VR for both robot programming and system programming. This creates a safer and more intuitive method for robot programming.
The module connects a manufacturing simulation software with the physical environment. This is done by having all the robots in the system connected to the industrial automation data server, and then connecting simulation software to the server. Then a VR headset is connected to the simulation software which allows for programming of each individual robot. It is also possible to program all the robots in a specified sequence.
To make the system more flexible and agile a wireless VR headset is used (oculus quest). The VR headset doesn't require any cables or cameras and it is therefore possible to program and interact with the virtual environment anywhere.
The structure of the system
The simulation software is Visual Components. There you have the model of manufacturing cell and then Visual Components Experience is used to interact with the simulation in VR.
The OPC UA server is the industrial automation data server which is used to connect the simulation software and the robots in the manufacturing cell.
Inputs and outputs
Input: All the joints values of each robot arm and the position of the mobile robot have to be added to the OPC UA.
Output: It will be possible to control the robot arms with joint control and to use position control of the mobile robot.
Formats and standards
Visual Components (simulation program), Visual Components Experience (VR functionality to simulation), OPC UA standard and a translator from Simulation software to robot movement (created in python).

Training material is under production. The tutorial shows how VR can be used for robot and system programming. _URL_

Reducing emissions of data centre activity
Microsoft Ireland Research has been working on electricity grid research that allows the exact energy consumption and emissions to be measured for any piece of computation performed in a data centre. This allows past or predicted emissions to be calculated for any computation performed in the cloud
and opens the doorway to measuring and reducing the emissions produced by data centres around the world.
In a paper presented at the 11th international conference on Electrical Power Quality And Utilisation
, Conor Kelly of Microsoft Ireland and Antonio Ruzzelli of University College Dublin outlined how data centre emissions can be calculated, and presented sample measurements showing that performing computation when ample wind energy was available on the grid emitted less than 1% of the emissions of the same piece of computation performed at another time when the bulk of the electricity consumed was produced by fossil fuel power plants.
As carbon taxes, emissions trading and environmental imperatives become an increasing influence around the world, and the EU looks to slash carbon emissions by 30 percent from 1990 levels by 2020, measuring and controlling the emissions resulting from the energy consumed in data centres will become as important as controlling the energy consumption itself. The research puts in place the calculations required to understand these emissions, which can in turn be used to inform their reduction. This opens up another path to reducing the growing emissions produced by data centres worldwide.
Putting a CO2 Figure on a Piece of Computation has been published by the IEEE and can be viewed here.

<Text-field bookmark="info" style="Heading 2" layout="Heading 2">Description</Text-field>A queue is a computer science data structure for storing objects that are to be processed in a "first come, first served" order. You place objects in a queue and, later, remove them for processing in the same order that they were placed in the queue. It is analogous to a theater line-up: the first person to arrive at the line is the first person to gain admission. For this reason, queues are often called FIFOs ("first in -- first out").To place objects into a container, and then access them in the opposite order, use a stack.Because you can only add items to the end of a queue, and remove them from the front, operations on queues are very efficient.In Maple, queues are heterogeneous; that is, any valid Maple object may be placed in a queue, and a queue may contain objects of different types. (In the examples, below, a queue containing both strings and integers is used.)In general, you should use only the operations described in this help page to manipulate queues. If you access directly the internal representation of queues, the results of subsequent queue operations are undefined.Use type(obj, 'queue') to test whether a Maple object obj is of type queue.A queue is created initially by using the procedure queue[new]. It returns a queue that is initialized and ready for use. Called with no arguments, new creates an empty queue. You can also create a queue initialized with a number of objects obj1, obj2, ..., objn by invoking new as new(obj1, obj2,..., objn). The queue that is returned will contain exactly the objects obj1, obj2, ..., objn, with obj1 at the front of the queue and objn at the back, and all of the objects in the specified order. The objects obj1, obj2, ..., objn may be Maple objects of any type, and need not all be of the same type.To determine whether there are any objects left in a queue, awaiting processing, you can used the function empty. The call empty(Q) returns true if the queue Q contains no items, and false otherwise. The argument Q must be a queue, returned by a previous call to new.Items may be placed on a queue by using the procedure enqueue. To insert the object obj at the end of a queue Q, you call the procedure as enqueue(Q, obj). The argument Q must be a queue, returned by a previous call to new.To remove the object at the front of a queue Q, use dequeue(Q). If Q is nonempty, the object at the front of Q is returned. It is an error to attempt to remove an item from an empty queue. You should check that your queue is not empty using empty before calling this function. The argument Q must be a queue, returned by a previous call to new.To examine the object at the front of a queue Q, without removing it, use front(Q). If the queue is nonempty, the object at the front of the queue is returned; otherwise, an error is signalled. You should check that your queue is not empty using empty before calling this function. The argument Q must be a queue, returned by a previous call to new.The number of items in a queue Q may be queried using the function length. If Q is a queue, then length(Q) returns the number of items in Q. The argument Q must be a queue, returned by a previous call to new.A queue Q may be cleared (that is, all objects removed from it) with clear(Q). This operation is done in linear time. The argument Q must be a queue, returned by a previous call to new.The order in which items are stored in a queue Q may be reversed using reverse(Q).An implementation of queues as objects is available using the SimpleQueue constructor.To use a queue function, either define that specific function alone by the command with(queue,function), or define all queue functions by the command with(queue).

Her nickname "Cricri" comes from the name of one of Michel Colomban's daughters, Christine.The structure of the aircraft is aluminum;The two engines develop 11 kW each (MC-15) for a maximum speed of 220 km / h in thermal version (283 km / h in electric version).
source.image: Clement PAGES
The Cri-Cri features a cantilever low-wing, a single-seat enclosed cockpit under a bubble canopy, fixed tricycle landing gear and twin engines mounted on pylons to the nose of the aircraft in tractor configuration. The aircraft is made from aluminum sheet glued to Klegecell foam.
Its 4.9 m span wing employs a Wortmann 21.7% mod airfoil, and has an area of 3.1 m2 (33 sq ft). The aircraft is also capable of aerobatics within the limitations of twin-engined aircraft.
The first flight of the prototype was made on 19 July 1973 and within a few days it had proved to be easy to fly and capable of aerobatics, being stressed to +10g and -5g. he cockpit canopy was carefully designed to direct effective airflow over the tail surfaces in this situation. The plans-built aircraft was also designed to be easy to store in a garage and tow on a trailer, with assembly and disassembly each taking only five minutes.


Event: 'Entangled Matter' by ELASTIC NATURE at The Crypt Gallery London
ELASTIC NATURE is an art research club bringing together interdisciplinary researchers, practitioners and thinkers around the broad subject of 'the future of nature' via artificial life, sympathetic synthetics, sensory realities, materiality and speculative bodies.
Founded by artist and researcher Becky Lyon through interactive workshops, seminars, breakfast salons and screenings ELASTIC NATURE stimulate conversation around the changing shape of nature. New forms of nature, artificial versus wildlife, how sensory mediation play a role in the understanding of nature and our perceived 'reality' of it or synthetic nature versus wild nature are some of the themes around which Becky Lyon articulates the conversation involving ELASTIC NATURE.
For its fourth session, they will be discussing the topic the interconnectedness of matter and hosting an exploratory discussion group as part of the programme of the Falling Stars / Stelle Cadenti exhibition curated by LUMEN. The conversation may include some of the next topics: Jane Bennet's seminal Vibrant Matter, what are the consequences of perceiving certain materials (such as a landfill) as dead? And how would that perception change if we perceived them as lively? How else have we privileged particular types of matter? What evidence or arguments exist, either scientifically or philosophical of the ability for the non-living matter to 'self-organise'? How is the search for extraterrestrial life impacting our perception of life on Earth? And can technology be considered nature?
This fourth event titled Entangled Matter is taking place this Saturday 26 at The Crypt Gallery in Euston (London) from 12:00 pm to 1:00 pm.

Little info about System Resource Database in (SQL Server 2008/2005)
The fifth system database in both versions (SQL Server 2008 - 2005) is Resource Database. In this DB we have all relevant information about systems objects and functions that we use every day in our daily routine, such as:
The Resource Database is the read-only DB, all sys.objects in SQL Server are organized in this DB physically and logically are appears in sys schema of every DB.
Physical name for the Resource Database are mssqlsystemresource.mdf - data file and mssqlsystemresource.ldf - log file, the location has been changed and it is different in both versions.
SQL Server 2008
SystemDrive:\Program Files\Microsoft SQL Server\MSSQL10.\MSSQL\Binn\.
SQL Server 2005
SystemDrive:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\
The Resource DB depends from master DB, so if you remove your master DB also you will move the Resource DB.
SQL Server cannot backup up the Resource DB, it can be done manually and the restore should be done manually as well, and must be careful to not overwrite the current Resource DB.
More and other related info about Resource DB can be checked from here.


nexus-4
Android may not have Siri, but it does have Voice Actions. Voice Actions are a powerful way to perform actions – searching, getting directions, making notes, setting alarms, and more – with just your voice.
Google's voice recognition has become surprisingly good, but – like all voice recognition – it isn't perfect. Be sure to enunciate clearly whenever you're speaking to a computer.
Performing Voice Actions
To start a voice action, either tap the microphone icon on the Google search widget at the top of your home screen or open Google Now and say "Google" out loud.
Your phone or tablet will start listening to your voice. You can now say something out loud to perform a voice action.
android-access-voice-actions
Perform a Google Search
The most basic – and obvious – of voice actions is as a simple Google Search. If you say something that Google doesn't recognize as another voice action, it will perform a simple Google search for it. If you say something like "photos of narwhals", Google will perform a search for narwhal photos and show them to you.
However, this feature also works hand-in-hand with Google's new knowledge graph. If you search for something Google knows the answer to – like "How many people live on Earth?" – Google will show you the answer to your question and speak it back to you. This feature will only get more powerful as Google's knowledge graph improves.
android-voice-search
Open an App
You can say "Open [app]" to open an app. For example, "Open Gmail" opens the Gmail app.
android-voice-open-app
Set an Alarm
To quickly set an alarm, say "Set alarm for [time]". You can say something like "Set alarm for 20 minutes from now" or "Set alarm for 7 a.m.".
You can also add a label. For example, you could say "Set alarm for 30 minutes from now, label, laundry is done."
android-set-alarm-with-voice
Make a Note
To make a note to yourself, say "note to self" and continue talking to leave your note.
android-note-to-self
This creates a note – both in audio and transcribed text – that will be emailed to your Gmail account. It's fine if the transcription isn't perfect, as you can play back the audio later.
note-to-self-in-gmail
Create a Calendar Event
You can easily create a calendar event by speaking it. For example, you could say "Create a calendar event: Business Lunch in New York, Friday at noon."
android-voice-create-calendar-event
Send an Email
Voice Actions can be used to send an entire email. For example, you could say "Send email to Bob Smith, subject, Our meeting, message, I'll be right there."
android-send-email-with-voice
Send a Text Message
Voice actions can send text messages in the same way it can send emails. For example, you could instead say "Send SMS to Bob Smith, message, I'm on my way."
android-send-sms-with-voice
Make a Phone Call
To make a phone call, say "Call" followed by a phone number, a contact's name, or a business.
android-call-a-phone-numer
Scan a Barcode
You don't need a separate barcode-scanner app on your phone. Whenever you want to scan a barcode or QR code, say "Scan a barcode" and Google will give you a barcode-scanner.
android-scan-a-barcode[3]
Identify a Song
You don't need a song-identification app like Shazam installed, either. Whenever you want to identify a specific song, ask "What's this song?" and Google will give you a song-identification widget that uses your device's microphone to identify a currently playing song.
(This only seems to work in countries with Google Music.)
android-what's-this-song
Listen to a Song
You can easily start listening to a song with voice actions. Just say "listen to" followed by the name of a song, artist, or album. You'll be able to choose an app, such as Play Music or YouTube.
android-voice-listen-to
Go to a Website
You can open a specific website by saying "Go to [website address]". For example, "Go to How-To Geek dot com" would bring you to our website.
android-voice-go-to-website[4]
View a Map
To view a map of an address or city, say "map of [location]". For example, you could say "map of Vancouver" or "map of 123 fake street, New York"
android-voice-view-a-map
Get Directions
To get directions to a location, say "directions to [location]". This opens the Google Maps app with directions to your specified location.
android-voice-directions
Start Navigation
To start getting turn-by-turn navigation directions to a location, say "navigate to [location]". This opens the Google Navigation app and starts navigating.
android-voice-navigate
Post to Google+
If you use Google+, you can use Voice Actions to post directly to it. Just say "Post to Google+" followed by your message.
android-voice-actions-post-to-google-plus
You can actually perform a voice action just by typing it into the Google search box. For example, typing "scan a barcode" into the Google search widget on Android and tapping the search key will bring up the barcode scanner.

Psychometric properties of the Revised Illness Perception Questionnaire: Factor structure and reliability among African-origin populations with type 2 diabetes
Research output: Contribution to journal › Article
Background: The Revised Illness Perception Questionnaire (IPQ-R) has been used extensively to measure illness perceptions of several patient populations. However, the instrument was developed using participants of mainly European-origin. The reliability and validity of the IPQ-R may therefore need to be established before use among populations of different ethnic and cultural origins. Objectives: This study investigated the factor structure and internal consistency reliability of the IPQ-R in African-origin patients with type 2 diabetes. Methods: In this cross-sectional study, 221 adults of African descent with type 2 diabetes completed the IPQ-R. Participants were recruited from patients attending diabetes and retinal screening clinics in the London boroughs of Brent and Hackney. Confirmatory Factor Analysis based on the covariance matrix was used to determine factorial validity for the Timeline-acute/chronic, Consequences, Personal control, Treatment control, Illness coherence, Timeline-cyclical, Emotional representation and three causal subscales of the IPQ-R. Composite internal consistency reliability for individual subscales was determined using Cronbach's alpha coefficients. Results: After eliminating three items and re-specifying six error covariances associated with large standardised residuals and low factor loadings, the hypothesised model adequately explained the covariance of African and Caribbean patients' responses to items of the IPQ-R. Also, composite reliability coefficients of all measured subscales were acceptable and inter-correlations between subscales were in line with those reported from other population groups. Conclusions: The findings in this study suggest that although the IPQ-R may be valid and reliable across cultures, investigators may need to modify (e.g. by rewording) some of its items taking into account any linguistic origins of their populations of study. Further evaluation of the IPQ-R (including the identity subscale) in larger samples of African-origin populations is also recommended. © 2011 Elsevier Ltd. All rights reserved.

In addition to these benefits, warm paving asphalt additives also offer improved pavement performance and longevity. The lower production temperatures and enhanced workability of warm mix asphalt result in a more uniform and dense pavement structure, which is less prone to cracking and rutting. This improved durability extends the service life of asphalt pavements, reducing maintenance costs and enhancing the overall sustainability of road infrastructure.
alt-9610
alt-9611
Overall, warm paving asphalt additives play a crucial role in modern road construction, offering a wide range of benefits that improve the environmental, economic, and performance aspects of asphalt pavements. By reducing energy consumption, lowering greenhouse gas emissions, and enhancing workability and compaction, these additives help to create more sustainable and resilient roadways that meet the needs of today's transportation infrastructure. As the demand for sustainable construction practices continues to grow, warm mix asphalt technology will play an increasingly important role in shaping the future of road construction around the world.
