One might need to insert a large amount of data when first populating a database. This section contains some suggestions on how to make this process as efficient as possible.
When using multiple INSERTs, turn off autocommit and just do one commit at the end. (In plain SQL, this means issuing BEGIN at the start and COMMIT at the end. Some client libraries might do this behind your back, in which case you need to make sure the library does it when you want it done.) If you allow each insertion to be committed separately, PostgreSQL is doing a lot of work for each row that is added. An additional benefit of doing all insertions in one transaction is that if the insertion of one row were to fail then the insertion of all rows inserted up to that point would be rolled back, so you won't be stuck with partially loaded data.
Use COPY to load all the rows in one command, instead of using a series of INSERT commands. The COPY command is optimized for loading large numbers of rows; it is less flexible than INSERT, but incurs significantly less overhead for large data loads. Since COPY is a single command, there is no need to disable autocommit if you use this method to populate a table.
If you cannot use COPY, it might help to use PREPARE to create a prepared INSERT statement, and then use EXECUTE as many times as required. This avoids some of the overhead of repeatedly parsing and planning INSERT. Different interfaces provide this facility in different ways; look for "prepared statements" in the interface documentation.
Note that loading a large number of rows using COPY is almost always faster than using INSERT, even if PREPARE is used and multiple insertions are batched into a single transaction.
COPY is fastest when used within the same transaction as an earlier CREATE TABLE or TRUNCATE command. In such cases no WAL needs to be written, because in case of an error, the files containing the newly loaded data will be removed anyway. However, this consideration only applies when wal_level is minimal as all commands must write WAL otherwise.
If you are loading a freshly created table, the fastest method is to create the table, bulk load the table's data using COPY, then create any indexes needed for the table. Creating an index on pre-existing data is quicker than updating it incrementally as each row is loaded.
If you are adding large amounts of data to an existing table, it might be a win to drop the indexes, load the table, and then recreate the indexes. Of course, the database performance for other users might suffer during the time the indexes are missing. One should also think twice before dropping a unique index, since the error checking afforded by the unique constraint will be lost while the index is missing.
Just as with indexes, a foreign key constraint can be checked "in bulk" more efficiently than row-by-row. So it might be useful to drop foreign key constraints, load data, and re-create the constraints. Again, there is a trade-off between data load speed and loss of error checking while the constraint is missing.
What's more, when you load data into a table with existing foreign key constraints, each new row requires an entry in the server's list of pending trigger events (since it is the firing of a trigger that checks the row's foreign key constraint). Loading many millions of rows can cause the trigger event queue to overflow available memory, leading to intolerable swapping or even outright failure of the command. Therefore it may be necessary, not just desirable, to drop and re-apply foreign keys when loading large amounts of data. If temporarily removing the constraint isn't acceptable, the only other recourse may be to split up the load operation into smaller transactions.
Temporarily increasing the maintenance_work_mem configuration variable when loading large amounts of data can lead to improved performance. This will help to speed up CREATE INDEX commands and ALTER TABLE ADD FOREIGN KEY commands. It won't do much for COPY itself, so this advice is only useful when you are using one or both of the above techniques.
Temporarily increasing the checkpoint_segments configuration variable can also make large data loads faster. This is because loading a large amount of data into PostgreSQL will cause checkpoints to occur more often than the normal checkpoint frequency (specified by the checkpoint_timeout configuration variable). Whenever a checkpoint occurs, all dirty pages must be flushed to disk. By increasing checkpoint_segments temporarily during bulk data loads, the number of checkpoints that are required can be reduced.
When loading large amounts of data into an installation that uses WAL archiving or streaming replication, it might be faster to take a new base backup after the load has completed than to process a large amount of incremental WAL data. To prevent incremental WAL logging while loading, disable archiving and streaming replication, by setting wal_level to minimal, archive_mode to off, and max_wal_senders to zero. But note that changing these settings requires a server restart.
Aside from avoiding the time for the archiver or WAL sender
to process the WAL data, doing this will actually make certain
commands faster, because they are designed not to write WAL at
all if wal_level is minimal. (They can guarantee crash safety more
cheaply by doing an
fsync at the
end than by writing WAL.) This applies to the following
CREATE TABLE AS SELECT
CREATE INDEX (and variants such as ALTER TABLE ADD PRIMARY KEY)
ALTER TABLE SET TABLESPACE
COPY FROM, when the target table has been created or truncated earlier in the same transaction
Whenever you have significantly altered the distribution of data within a table, running ANALYZE is strongly recommended. This includes bulk loading large amounts of data into the table. Running ANALYZE (or VACUUM ANALYZE) ensures that the planner has up-to-date statistics about the table. With no statistics or obsolete statistics, the planner might make poor decisions during query planning, leading to poor performance on any tables with inaccurate or nonexistent statistics. Note that if the autovacuum daemon is enabled, it might run ANALYZE automatically; see Section 23.1.3 and Section 23.1.5 for more information.
Dump scripts generated by pg_dump automatically apply several, but not all, of the above guidelines. To reload a pg_dump dump as quickly as possible, you need to do a few extra things manually. (Note that these points apply while restoring a dump, not while creating it. The same points apply whether loading a text dump with psql or using pg_restore to load from a pg_dump archive file.)
By default, pg_dump uses COPY, and when it is generating a complete schema-and-data dump, it is careful to load data before creating indexes and foreign keys. So in this case several guidelines are handled automatically. What is left for you to do is to:
Set appropriate (i.e., larger than normal) values for maintenance_work_mem and checkpoint_segments.
If using WAL archiving or streaming replication, consider disabling them during the restore. To do that, set archive_mode to off, wal_level to minimal, and max_wal_senders to zero before loading the dump. Afterwards, set them back to the right values and take a fresh base backup.
Consider whether the whole dump should be restored as a single transaction. To do that, pass the -1 or --single-transaction command-line option to psql or pg_restore. When using this mode, even the smallest of errors will rollback the entire restore, possibly discarding many hours of processing. Depending on how interrelated the data is, that might seem preferable to manual cleanup, or not. COPY commands will run fastest if you use a single transaction and have WAL archiving turned off.
If multiple CPUs are available in the database server, consider using pg_restore's --jobs option. This allows concurrent data loading and index creation.
Run ANALYZE afterwards.
A data-only dump will still use COPY, but it does not drop or recreate indexes, and it does not normally touch foreign keys. So when loading a data-only dump, it is up to you to drop and recreate indexes and foreign keys if you wish to use those techniques. It's still useful to increase checkpoint_segments while loading the data, but don't bother increasing maintenance_work_mem; rather, you'd do that while manually recreating indexes and foreign keys afterwards. And don't forget to ANALYZE when you're done; see Section 23.1.3 and Section 23.1.5 for more information.
You can get the effect of disabling foreign keys by using the --disable-triggers option — but realize that that eliminates, rather than just postpones, foreign key validation, and so it is possible to insert bad data if you use it.

line is known throughout the Pokémon community as the ideal "HM slave", especially in the Sinnoh
region. While Bidoof can only learn Cut
) and Rock Smash
can learn Cut (HM01), Surf
), Rock Smash (HM06), Waterfall
) and Rock Climb
), as well as Dive
on some occasion, thanks to the change from a pure Normal-type
to a dual Normal- and Water
-types. These cute yet versatile Pokémon abound in Sinnoh, Unova
, and Alola
- but what are their real-world inspirations?
Our analysis naturally begins with Bidoof itself. Bidoof is inspired by the mountain beaver
, scientifically named Aplodontia rufa
. Though it is a North American rodent, it is not actually a true beaver, being a closer relative of the squirrel
- thus explaining why it is listed in the Pokédex
as the Plump Mouse Pokémon!
The mountain beaver is the last living member of its genus and family and despite the name, it only superficially resembles a beaver due to its size, strong odor, preference for watery locations and propensity for consuming seedlings; it is actually considered a living fossil
due to its primitive attributes. Unlike 'true' beavers, they do not fell trees to build dams
, live in lodges, or communicate by slapping their tails. They are nocturnal
and can climb trees for food when needed, but mostly eat ferns
and other plants which are toxic to other animals, suggesting a natural immunity to some poisons.
Mountain beavers are found in the Cascade Mountain Range
, Olympic Mountains
, the Klamath Mountains
, and the Sierra Nevada Mountain Range
. They do not function well in colder climates, being unable to conserve their heat. They also do not hibernate
, though much like beavers and other rodents they can create burrows consisting of deep dirt tunnels, wilted plants, and hay. Known predators of the mountain beaver include bobcats
, golden eagles
, and owls
; they are also prone to hosting largest known species of flea, the mountain beaver or giant mountain beaver flea
. Their breeding season is between January and March, typically giving birth to two young. They live between five to ten years and are typically antisocial.
Bibarel, on the other hand, is based on species of 'true' beavers, of which there are two main kinds - the North American beaver
, Castor canadensis
, which covers most of northern North America, and the Eurasian Beaver
, Castor fiber
, which lives in parts of Western Europe. While the Eurasian beaver possesses a more elongated skull, narrower tail and lighter color, the North American beaver has a narrower body. Taken together, beavers are the world's second largest rodent, after the capybara
. Their skulls are relatively large to accommodate their famous teeth, while their hands and feet are dexterous, allowing for gripping, manipulating and digging. So close is their evolutionary path, both species of beaver can breed with one another.
Both types of beaver live in freshwater ecosystems
, preferring flatter regions close to water, being herbivorous
and eating plants near their water home. Beavers are famous for building lodges and dams, normally as a community activity. Many beavers build canals between their lodges and their food sources, locking the lodge in place. Though they are nocturnal and do not hibernate, beavers can spend more than 24 hours awake when setting up their dens for the winter. It may be tempting to think that beaver dams can harm environments by restricting the flow of water, but they actually help provide a habitat for many sensitive plant and animal species, improve water quality and control floods - just as Bibarel does.
Beavers can live up to ten years on average and their basic social unit is the family, which usually features a monogamous pair and at most ten other members, with litters of at least four babies being born per year. Beaver families greet each other with whines and various other sounds. They also specialize in using their tails to warn others of impending dangers - such a warning system allows for members of the community to hide in their lodges, dens, and deeper water, depending on where they are.
Well I'll be dammed - even the Bidoof line packs some surprising evolutionary secrets! We hope this article gave you a new perspective on this oft-maligned Pokémon, and that you have a happy Bidoof Day!

connection to their listenership. Importantly, it also enables the hosts to mediate the pornography they watch through an aural-only medium which allows a distance to the visuality of pornographic videos which overwhelmingly relies on the objectification of female bodies.
Abstract: As intimacy emerges as a key concept in podcast research, it becomes increasingly urgent to consider the multifaceted ways in which it interacts with the medium. This article advances research on podcasting intimacy by understanding intimacy as undergoing a continual process of culturally contingent negotiation and examining how podcasting participates in that negotiation. Instead of treating intimacy as an inherent part of podcasting, it demonstrates how podcasts can create intimacy and use it to form connections among members of a fan public. To do so, this article uses the first season of Within the Wires (2016) to show how narrative repetition constructs fan-based intimate publics. Within the Wires is an alternate reality fiction podcast whose first season takes the form of relaxation tapes. Throughout the podcast, the narrator repeats specific lines, phrases, and memories that the listener comes to recognize. By retooling Roland Barthes and Marianne Hirsch's work on recognition and community building in photography for use in sound research, this article develops a theoretical framework for understanding the temporalities of recognition in podcasting. Using this framework, the article posits that Within the Wires uses non-narrative repetition alongside its aural aesthetics to create an intimate public through recognition. The podcast extends that recognition into its monetizing paratexts, making it possible for listeners to recognize themselves and others as fans. The first section of this paper defines recognition and its relationship to time, the second considers how recognition works within the show's fandom, the third looks at recognition within Within the Wires' monetizing paratexts, and the final tracks how the podcast finds horror in the breakdown of this system. The article argues that Within the Wires presents intimacy and creates fan-based intimate publics through the experience of recognition.
Chase Gregory: Crossing Both Ways: Sarah Jones, The Moth Radio Hour, and the Disruptive Potential of Voice
Abstract: This paper examines an episode of popular storytelling podcast The Month, titled "A Walk on the West Side" (2014), in order to explicate and uncover how gender, race, and class might attach to certain voices. In this episode, Jones (a stage performer, writer, and gifted impressionist) first relates her memories of being typecast as black female stereotypes; she then tells the story of being pulled over by LAPD a few days later, under suspicion of sex work. Ultimately, Jones baffles the cops who detain her by affecting a flawless British accent, disrupting their assumptions. Her story—told on the podcast in a myriad of different voices—literally speaks class, race, and gender into being, only to challenge the fixity of these signs, showcasing the simultaneously disruptive and productive potential of speech.
Abstract: From a feminist media studies and cultural studies perspective, the contribution explores the fascinating, yet overlooked podcast series Alice Isn't Dead (2016-8). The podcast thematically centers around the complex relationship of culture and distance and develops different understandings of culture, as well as the experience of distance in a geographical, socio-economic (class mobility), or interpersonal-romantic sense. Tracing these conceptions and their attempts to define a collective US-American identity differently, the contribution focuses on the podcast's narration in the form of radio monologues by its protagonist, the exceptional trucker character Keisha, its take on the road trip and (female) mobility, as well as its representation of a queer love story. With an eye for the intersectional effects of gender, race, and sexual orientation, these readings mobilize a variety of cultural artifacts to explore the particular affordances of serialized fictional podcast storytelling. Of particular interest to the contribution are the intertextual echoes of tropes and themes of the road trip narrative and the road movie, as well as the podcast's ending as a turn toward homonormativity that is inconsistent with the queer temporalities and the capitalist critique developed by the podcast during its three seasons.
Abstract: In contemporary mainstream media there is a tendency to represent LGBTQ+ characters stereotypically, or even kill them off. This trope is called 'bury your gays' and it has done much to discredit and delegitimise representation. Even though the percentage of queer representation in mainstream media has improved, a viewer could be forgiven for thinking that, overall, popular culture does not think highly of the LGBTQ+ community for continuing to perpetuate these narrative arcs. The McElroy family's popular actual-play podcast The Adventure Zone (TAZ) initially portrayed queer characters in the 'bury your gays' trope by killing off a canon lesbian couple in their first season. As four self-proclaimed 'straight, cis, white dudes', the family initially performed their characters by reflecting what they had seen in mainstream fiction. After engaging with their audience and learning why this was upsetting, they changed the story to reverse the trope; unburying their gays by bringing the characters back to life. Since then, they have consistently introduced more queer characters and, in their latest season, have also introduced nonbinary characters. By tracking the introduction and development of queer representation in TAZ podcast episodes – both the game episodes and the meta-episodes bookending each season – the McElroys' education and integration of this new information into narratives is demonstrable. The representation of queer characters in TAZ shows that podcasts are not just a platform for LGBTQ+ creators to educate their audience; they can also act as a participatory storytelling medium in which creators can be educated in gender and sexuality by their audience.
Deniz Zorlu and Nazlı Özkan: Women on Twitch Turkey: Affective Communities and Female Solidarity Under Patriarchy and Postfeminism
Abstract: This article examines the experiences of female streamers and podcasters on Twitch Turkey primarily through in-depth interviews conducted with 35 respondents. Despite the platform's growth as one of the most widely visited social media sites and the biggest online game streaming platform, there is limited research as to how gender identities and geographical location shape streamers' experiences and usage of the platform. We argue that female streamer's use of Twitch Turkey is marked by combined patriarchal pressures and neoliberal, postfeminist thrust for aggressive competitiveness. Sexual harassment is the major problem for women, and pervasive patriarchal relations of domination affect all female streamers' usage of the platform, who often find themselves scrutinized and criticized for their body images, clothing, and gaming performances. In exerting control over their behavior, patriarchy, however, affects women in different ways based on their cultural preferences and personal habits. We also argue that Twitch Turkey tends to push women to adopt postfeminist subjectivities to rigorously compete with each other for limited viewership, sponsorship, and income opportunities. However, these pressures and constraints are resisted and re-negotiated especially through the formation of female solidarities and affective communities in online streaming.

Phase transformations in steels: Volume 2: Diffusionless transformations, high strength steels, modelling...
Elena Pereloma, David Edmonds,
2012 | ISBN-10: _PHONE_ | 680 pages | PDF | 49 MB
The processing-microstructure-property relationships in steels continue to present challenges to researchers due to the complexity of phase transformation reactions and the wide spectrum of microstructures and properties achievable. This major two-volume work summarizes the current state of research on phase transformations in steels and its implications for the emergence of new steels with enhanced engineering properties.
Volume 2 reviews current research on diffusionless transformations and phase transformations in high strength steels, as well as advances in modeling and analytical techniques which underpin this research. Chapters in part one discuss the crystallography and kinetics of martensite transformations, the morphology, substructure and tempering of martensite as well as shape memory in ferrous alloys. Part two reviews research on phase transformations in high strength low alloy (HSLA) steels, transformation induced plasticity (TRIP)-assisted multiphase steels, quenched and partitioned steels, advanced nanostructured bainitic steels, high manganese twinning induced plasticity (TWIP) and maraging steels. The concluding two parts review advances in modeling and the use of advanced analytical techniques to improve the understanding of phase transformations in steels.

How to Use In-Store Messaging Successfully
Learn what makes a successful in-store message display as well as how text-enabling your ad can be the key to driving more sales.
Featured image for the article
Did you know 69% of shoppers spend 30 minutes or more in a retail store?
And while COVID-19 may result in shoppers wanting to get in and out of stores as quickly as possible, it only means it's more important than ever to capture their attention.
So how do you use that time to sell, upsell, and engage? The secret is in your in-store messaging.
In this article, we'll explain what in-store messaging is, what you need to make yours successful, and the potential outcomes of a successful in-store marketing strategy.
What Is In-Store Messaging?
In-store messaging is simple, objective-based advertisements continually served to shoppers at your location.
It could be an audio message played over a store loudspeaker, or a visual message like a sign, display, or tag.
Since the messaging serves customers who are already in your location, the focus is on driving sales. And one of the top tactics in-store messaging takes is to create a sense of urgency.
For example:
 - An announcement over the loudspeaker sharing a sale on jeans ending TODAY
 - Big, bright, sale signs hung around the store
 - Cornered-off and clearly marked clearance sections that, thanks so the piled display, represent a sense of scarcity
 - Attention-grabbing graphics that urge you to take action now while a product is on your mind
Why Is In-Store Messaging Successful?
We ask, "why is in-store messaging successful" vs. "is it successful" for a reason. The numbers speak for themselves.
 - 80% of shoppers say in-store messaging influences their buying decisions
 - 82% of shoppers make unplanned purchase decisions in-store
 - 72% of shoppers find in-store audio promotions helpful to their experience
In-store advertising can help in increasing sales up to 16% on average thanks to serving the right message at the right time.
Here's how it works:
 1. Know your audience: Is your product a luxury item, a bargain brand? Knowing the type of person shopping for your item will help you determine the kind of message needed.
 2. Identify their problem: What keeps them from making a purchase when they're in your store?
 3. Offer a solution: Provide the anecdote to their purchase problems. Too expensive? Hook them with a coupon!
 4. Wrap it into a quick message: Choose your medium—in-store signage or audio clips are the most popular—and share your message and value directly.
Here's an example that shows all four steps in action.
Let's say your store sells two brands of toilet paper (one generic, one name-brand). You'll want to upsell the folks who typically buy generic. You'd do this by targeting their cost-savvy habits with messaging that offers a bulk discount on the name brand that's too good to pass up!
In-Store Messaging Examples
When it comes to the last step above, sometimes finding a way to package your message can be tough. Especially if you only have a few short moments of aisle-browsing attention.
So, here are some examples of successful in-store messaging examples to get your creative juices flowing.
In-Store Posters

The example above shows the sense of urgency described above ("One Day Only 50% off Storewide"). And while your discounts may not be as extreme as the example above, the simple values-based copy demonstrates the point precisely.
All your sign needs is an eye-catching visual, the values statement, and you're in business.
Checkout Signage

This example follows the same psychology as keeping candy and small objects by the checkout counter. While your customers wait to check out, serve them some advertisements that promote an impulse purchase. This is also the same driving force behind the success of "keep the change" checkout donation drives.

In-store messaging isn't just for retail. Restaurants are also a great place to capture the attention of your audience during the 30-60 minutes they're dining with you. Tabletop messages are an excellent way to upsell a meal with enticing dessert photos. Or, like in the example above, encourage gift card sales!
Overhead Music
70% of retailers agree that in-store music increases sales, and the right kind of music can influence shoppers to spend even more. Pepper in audio announcements over the speaker sharing deals and discounts, and you'll boost your efficacy even more.
Text Enabling Your Store Displays
A study by Euclid Analytics found that 83% of consumers said they use their smartphone while they shop at brick-and-mortar stores.
But just because they're looking down at their device it doesn't mean they can't still access your in-store messaging. It simply needs to go mobile!
95% of text messages are read within three minutes of being received. This means the chances of an offer sent while a customer is in-store has a high chance of convincing them to make a purchase.
Getting customer's phone numbers can also be the gateway to collecting more valuable information such as emails, zip codes, and birthdays.
You can use the phone numbers you collect to text out offers, coupons, and other material that will drive more foot traffic to your brick and mortar or online store.
A popular way to quickly collect customer's phone numbers in-store is to create a QR code shoppers can scan while standing in line to unlock a coupon. Or, add a keyword and phone number to in-store signage for customers to text in to learn more about a sale.
💡SimpleTexting Tip: A keyword is a word or phrase that your customers can text to a 10-digit number or designated text short code. When they do, they're signing up for future SMS marketing campaigns.
Try it out for yourself to see how easy it can be to collect shopper information in a (camera) snap!
Businesses like Delta Sonic have seen amazing results with mobile advertisements for their stores at gas pumps in their area. To date, they've acquired over 50,000 text subscribers who regularly receive and respond to their offers!

they had to keep that knowledge hidden, therefore, they altered and anagrammatized the Turkish expression to come up with the name "STONEHENGE".
Alternatively, the name STONEHENGE, rearranged letter-by-letter as "GON-ENE-TESH", is a restuctured, Anglicized form of the Turkish expression "GÜN ANI TAŞ" or "GÜN TAŞ ANI " meaning "Sun monument in stone".
Stonehenge is very much a sun-emulating religious structure made in an "EYE" (i. e., Turkish "GÖZ") format. In the language of ancient Turanians, that is, Turkish, the Sun was called "eye" of the Sky God.
Turkish word GÜN (GÜNEŞ) means "sun", ANIT means "monument", ANI means "monument, reminder, remembrance", TAŞ means "stone".
The Sonehenge monument is claimed by the ancient native peoples called DRUIDS as being a monument done by their ancestors. The name Druid is defined as "a priest, magician, or soothsayer in the ancient Celtic religion. A member of a present-day group claiming to represent or be derived from this religion". DERIVATIVES of the name are Druidic (adjective), Druidical(adjective), Druidism (noun). ORIGIN from Latin druidae, druides (plural), from Gaulish; related to Irish draoidh 'magician, sorcerer.' [Oxford American Dictionaries.]
The name DRUID, rearranged letter-by-letter as "DUR-ID", is an altered, restuctured, Anglicized form of the Turkish expression"TUR IDI" (TURK IDI) meaning "he/she was TUR", "He/she was TURK". Ancient Turanian SHAMANS (i.e., "KAM" in Turkish) are regarded as "magicians" and "soothsayers" by the westerners, although they were known as highly enlightened and specialized "medicine men". Actually, the name SHAMAN is from Turkish word "IŞIMAN" meaning "man of light", that is, the "enlightened man".
Even the name DRUIDIC, rearranged letter-by-letter as "DURC-IDI", is an altered, restuctured and Anglicized form of the Turkish expression "TÜRK IDI" (TUR IDI) meaning "he/she was TURK", "He/she was TUR".
So this shows that the ancestors of Druids were Turkish speaking Turanian Tur/Turk/Oguz peoples who were living some 5,000 + years ago in what is presently known as the so-called "British Islands" or "Brittania". This is another proof that the ancient world was a truly Turanian world before the Turanians in the continent of "Europe" were Aryanized and their Tur/Turk/Oguz identity obliterated by the invading so-called "Indo-Aryans" or "Europeans". Ancient native peoples of "Europe" were Turkish speaking Turanian Tur/Turk/Oguz peoples - contrary to all kinds of denial explanations that have been designed to change the ancient Turanian history of the world. Even the name SCOT of Scotland, is an altered form of the Turkish name ISKIT, that is, the ancientSAKA Turks, who retain their original name in a semblence format.
In concluding, it can be said that the Göbekli Tepe
civilization artifacts are most likely a small portion of the ancient
Turanian civilization that has recently shined back into daylight. It is
part of an ancient world wide civilization of Turanian Tur/Turk/Oguz peoples
that were much earlier in time
than the later Aryan "Indo-European"
and "Semitic" civilizations. These late-comer Aryans and Semites made sure
that they not only usurped every aspect of the ancient Turanian
civilization, but that they also destroyed and obliterated the Turanians in
every way possible - so that the world would not be aware of that very
ancient civilization. Much of the obliteration was done by altering and
restructuring the Turanian Turkish language into different formats as
referred to in Genesis 11.
I also shared my observations of the pictures from both the Göbekli Tepe findings and also from much older findings at Malta, a Central Asian region of Altai Mountains, and from the Sumerians - and compared them with each other. They all seem linked to each other. Labeling these ancient people of Göbekli Tepe as "hunter-gatherers" (as some have done) is a very unfair and unwarranted put-down in view of the artifacts that they left behind. It is fair to say that the Göbekli Tepe civilization was much more advanced than any hunter-gatherer society would be.
In addition to Göbekli Tepe findings, the Turanian artifacts found at Malta, near lake Baikal, Central Asia make the ancient Turanian civilization older than 15,000 years.
This concludes my study (at present) of the Göbekli Tepe findings.

Best wishes to to you and to all,
Dear sir, I have been reading some of your material at _URL_ I was wondering what your view on Gobekli Tepe is, as it may seem a perfect fit for you that there was an advanced civilisation there maybe more than 10.000 years ago. Best regards, Thomas Roed Jakobsen Sendt fra min iPhone

Wellbeing in New Zealand: a reliability and validity study of the New Zealand Sovereign Wellbeing Index
Reid, Amanda Kate
MetadataShow full metadata
Background Measurement tools that evaluate personal, social and occupational life domain wellbeing are increasingly being used to measure how people are feeling and flourishing. The New Zealand Sovereign Wellbeing Index (NZSWI) is a measure specifically developed to evaluate the wellbeing of New Zealanders, and to track how their wellbeing is changing over time. Best practice in psychometric measurement requires sound assessment in order to be useful for those interpreting and utilising the results of wellbeing measures, and the NZSWI's reliability and validity has yet to have been investigated. The aim of this research was to determine the test-retest reliability, internal consistency, and construct validity of the NZSWI. Methods The aim of this research was to determine the test-retest reliability, internal consistency, and construct validity of the New Zealand Sovereign Wellbeing Index. Seventy-one adults aged 18 years and over completed a survey battery, including the New Zealand Sovereign Wellbeing Index and additional validated wellbeing measures at two time points, one week apart. Test-retest reliability between the two time points was analysed by calculating an intraclass correlation coefficient. Internal consistency was assessed at time point 1 using a Cronbach's alpha correlation coefficient. Construct validity, both convergent and discriminant, was evaluated against validated psychometric tools using Spearman's rank correlation coefficient. Results With regard to test-retest reliability, 78 items (89%) displayed substantial reliability (Cronbach's coefficients between 0.61 and 1.0). Ten items (11%) had moderate reliability (coefficients between 0.41 and 0.60). For internal consistency, five of the twenty total topic headings (25%) had coefficient alphas above 0.70, eleven (55%) had coefficient alphas between 0.50 and 0.69, two (10%) had alphas between 0.40 and 0.49, and two (10%) had coefficient alphas under 0.25. With regard to convergent validity, all items measured within the 15 topic tables displayed strong validity with Spearman's coefficients above 0.50. For discriminant validity, one topic (11%) returned a small correlation, six topics (67%) returned medium correlations, and 3 two topics (22%) returned strong correlations, therefore demonstrating variable validity in this aspect. Conclusion On the whole these results suggest that the New Zealand Sovereign Wellbeing Index is a reliable and valid psychometric measurement tool for assessing wellbeing constructs in a New Zealand adult population.

Wheelphone main wiki
Phone inclination
In some applications you need that the phone mounted on the robot has a longer view with the back camera and this can be accomplished adding a small piece of plastic with which you can adjust the tilt. In our lab we designed a simple extension that let choose between two inclinations, the following figures compares the normal inclination (no extension) and the others two (with the extension in one side and the other side):
The installation is very easy: just insert it in the case of the robot.
An application that works better with this extension is the markers navigation app that need to detect markers at long distance.
Extra stabilization
Nowadays phones are always bigger and this is normally an advantage for the user, but the Wheelphone could get in troubles loosing the balance easier. For this reason a little weight can be placed on front of the robot to let it be more stable, especially when little ground obstacles need to be overcome. The following figure shows the plastic container (filled with lead) positioned on front of the robot thanks to the "lego connectors":
The plastic container is covered with some nice pictures, but you can put whatever images you like.
Play with lego
The Wheelphone robot has some "lego connectors" around in the case (i.e. in the bottom side near the ground sensors, in the front side over the proximity sensors, in the wheels,...). The following figures show some lego pieces attached to the Wheelphone, e.g. you can attach two arms and play with a ball, or you can send some message to your friends,...your fantasy is the limit.
Artist extension
Brings out your artistic side with this extension that let you attach a pen in the back side of the robot. The installation is very easy, the piece must be framed to the case as shown below:
The following video shows an example:
It's not a perfect heart, it's art ;-)
Magnetic drag
The same plastic extension used to work with a pen can be used to drag some others thinks thanks to a magnetic connection; insert a little magnet inside the hole as shown in the following first picture, then you are able to be for example a locomitve:
Video recording
If you are interested in recording a video directly on the phone that is connected to the robot, thus having the perspective of the robot while is moving, you can follow these steps:
 1. connect the phone to the robot and start the monitor application
 2. take the robot in your hands and give the robot a desired speed and enable obstacle avoidance (and cliff avoidance if you are moving on a table)
 3. press the home button of the phone
 4. start the camera app from the Android system and start recording
 5. place the robot on the ground and let it move around
 6. when you are satisfied take the robot, stop the recording and turn off the robot

720 DEGREE IMAGE Bog roll camera. (2 x 360 degrees).
One of the most rewarding as well as bewildering approaches to pin-holing is imaging on the inside of a cylinder. This is an excellent teaching tool, forcing the user to mentally combust whilst getting a healthy understanding of aiming without a viewfinder. It is also a great use for the inside of a used toilet roll. For teaching and general experimentation, photographic paper works fine for all the methods below.
Pringles box (10 x 8), Poster tube (5 x 7) and toilet roll tube (5 x 4) cameras.
The last time I taught this, the insides of toilet rolls were taken from all the conveniences of the University, making me highly unpopular with the cleaners!
1. Get the inside of a toilet roll.
2. Flatten a sheet of aluminium cut out from a beer – coke can.
3. Cut out two circles of aluminium the same diameter as the roll, using it as a template.
4. Push a pin through the center of each of the circles of aluminium.
5. Sand down on both sides of the hole using 1200 grit emery paper, making the area of the hole as thin as possible. (This enables the hole to image at an acute angle, through a slot rather than a circular hole).
6. Check how thin the metal is by tilting the circle of metal up to a light and observing when the hole disappears.
7. Use black insulation tape to fix the pinholes onto each hole of the tube.
8. Cut the roll in half and adhere a strip of black card to form a light tight sleeve for the other half of the tube to slide into.
9. Make two shutters out of black insulation tape to cover each of the holes.
The roll needs to be kept still which can be done with a rubber band and a short pen. Avoid sunlight entering either of the holes. Each shutter can be removed to expose either side alternately.
Getting ones head around two 360-degree images back to back is great fun, making this one of the most enjoyable bouts of pre-visualisation chaos one can have! Try and position the roll close to a subject so no area is left blank (ie the sky). In the same way, if the roll is positioned on the ground, placing the camera on a newspaper will put detail into the foreground the camera is resting on. Initially 'pointing' the camera towards a wall (from a distance of about a foot), will give the user some vague idea as to what is happening. The area directly in front of the pinhole is excluded from the picture, but with a circular 360 degree area either side of the hole being recorded. Due to the increasing pinhole – emulsion distance (inverse square law stuff) the image fades the further it is from the hole, so allowing the second image to form from the halfway point.
About 3 seconds each side in sunlight when using photographic paper, (semi matt reduces internal reflections.) The final photo can be rolled into a cylinder, (Image outwards), to show the two images joining up.
Advanced - Using film.
If you fancy using film, the toilet roll has the same inside area as a sheet of 5x4. Make a smaller hole by pushing only the tip of the pin through the metal then follow the same procedure with the emery paper. This can also be used (for close ups) with a couple of flashguns to avoid camera shake. (see the self portrait on the main index page of the website). If you have a 10x8 enlarger lying around, as well as loads of spare cash, a Pringles box takes a sheet of 10x8 film.
A shiny cylinder, the same diameter as the roll used to create the image can be placed on the photograph and the image viewed in correct perspective off the reflection in the same way as in the 18th century bods used to do with paintings reflected in goblets. They didn't have toilet rolls though.

The spotted seal (Phoca largha ), also known as the larga seal or largha seal, is a member of the family Phocidae, and is considered a "true seal". It inhabits ice floes and waters of the north Pacific Ocean and adjacent seas. It is primarily found along the continental shelf of the Beaufort, Chukchi, Bering and Okhotsk Seas and south to the northern Yellow Sea and it migrates south as far as northern Huanghai and the western Sea of Japan. It is also found in Alaska from the southeastern Bristol Bay to Demarcation Point during the ice-free seasons of summer and autumn when spotted seals mate and have pups. Smaller numbers are found in the Beaufort Sea. It is sometimes mistaken for the harbor seal to which it is closely related and spotted seals and harbor seals often mingle together in areas where their habitats overlap.
Show More
The reduction in arctic ice floes due to global warming led to concerns that the spotted seal was threatened with extinction. Studies were conducted on its population numbers, with the conclusion, as of October 15, 2009, that the spotted seal population in Alaskan waters is not currently to be listed as endangered by NOAA.
Show Less
Appearance
The Spotted seal is a "true seal" with a small body, a rounded head and short flippers. The coats of adults have dark spots over light gray to silver. As pups they are pure white. These ice dwellers form seasonal family groups and prefer open seas.
Distribution
Geography
Spotted seals are found in areas around the North Pacific Ocean, from Alaska's coast, through the Bering Sea, and to the Sea of Okhotsk, Yellow Sea, Sea of Japan, and Bohai Sea. They can also be found as far to the north as the Arctic Ocean, to the west to about 170 degrees east, as well as eastward to Canada in the Mackenzie River Delta. This species inhabits the southern edge of pack ice from winter until early summer, and then moves into coastal areas, such as river mouths, for late summer and autumn. It usually hauls out and breeds on ice, but sometimes comes ashore on sand bars and beaches, and at some sites along the coast of Asia, they will breed on small, remote islands.

Habits and Lifestyle
Detailed studies on the Spotted seal are difficult, as these animals are wary and do not tolerate humans well, quickly entering the water when sensing a possible threat. They are solitary for parts of the year, gregarious at other times. They are frequently seen at haul-out sites on ice or on the shore where several individuals or a large group leaves the water to gather. Usually haul-outs are near abundant food sources. Such groups are sometimes called "onshore associations" or OAs. Four types of OAs are seen during the year. These are: preliminary, reproductive, molting, and recovery, the last being a phase to rehabilitate after the reproduction and molting phases, which are energy intensive. OAs can vary in the gender and age of individuals during the year as the purpose of the OA changes.
Seasonal behavior
Diet and Nutrition
Spotted seals are carnivores (piscivores), they mainly eat fish, especially herring, pollock, capelin and cod. They also eat mollusks and crustaceans.

BABY NAME
pup
Spotted seals are annually monogamous instead of polygynous, which is unusual among seals. Mating pairs form when females are ready to bear a pup from the mating of the previous year. The pair stays together until the pup is weaned and the female mates again. Breeding is usually around April or May, in the spring, but can take place in Asian waters as early as January. A single pup is produced the following spring. Gestation will last 7 to 9 months, though delayed implantation after breeding may extend the pregnancy to nearly a year. When 2 to 4 weeks old pups are weaned, their lanugo has been shed and they are able to leave the ice to start learning to forage in the water. Females reach maturity at 3 to 4 years of age and males usually at 4 to 5 years old.
Population
Population threats
Commercial harvesting of fish is a threat to Spotted seals because of competition for prey species with fisheries. Injuries and entanglements from fishing gear are another problem, especially off the Japanese coast and in the Sea of Okhotsk. Fishermen in some areas shoot small numbers of these animals, and small culls also take place to limit the damage to fisheries. Poor environmental conditions injure or kill this species, mainly pups that get caught between the sheets of pack ice that collide. A newer, potentially bigger risk is from gas and oil exploration and extraction, which could destroy their habitat and cause direct disturbance to seals as well as the risk of oil spills and pollution. The biggest threat is the predicted reduction of sea ice dye to climate change.
Population number
According to the IUCN Red List, the total Spotted seal population size is around 640,000 individuals, with over 460,000 seals in the Bering Sea; in the Sea of Okhotsk -180,000 individuals, and around 3,300 individuals in the Sea of Japan and the Yellow Sea. Currently spotted seals are classified as Least Concern (LC) on the IUCN Red List.
Ecological niche
As piscivores, Spotted seals may have an influence on populations of fish.
Fun Facts for Kids
 - Spotted seals are called these names by the Alaskan Natives: qasigiaq (Inupiaq), issuriq (Yup'ik), gazigyaq (St. Lawrence Island Yupik), and issuri (Nunivak Island Cup'ig).
 - Spotted seals were once believed to be the same as the harbor seal species. Their ranges do overlap and there has been some interbreeding.
 - The Spotted seal is the only seal breeding in China.
 - In the summer Spotted seals use the coastal haul-outs, a reason being so they can get warmed in the sun.
 - Spotted seal pups take a longer time than other ice seal species to learn to how to swim and dive.

Boston Carbon Corporation to Donate 27,000 Tons of Greenhouse Gas Credits to the DNC Credits will offset emissions from travel to and from Boston
 BOSTON, July 26 /PRNewswire/ -- The Boston Carbon Corporation, (BCC), a
 leading consulting company advising clients on profitable environmental
 remediation techniques, is donating 27,000 Greenhouse Gas Certified Trading
 the estimated 27,000 tons of CO2 emissions that will be generated by
 the week of the convention.
 Boston Carbon's donation, made through the Coalition for Environmentally
 Responsible Conventions (CERC), is helping the Democratic National Convention
 Committee achieve its goal of becoming America's greenest political
 convention. These trading credits certify that an actual reduction of 27,000
 tons greenhouse gas (GHG) emissions has been achieved and that the reduction
 meets all of the criteria laid out by the United Nations Framework Convention
 on Climate Change. The 27,000 tons of emissions offset by this donation are
 the equivalent to the CO2 generated by approximately 90,000 homes during the 5
 days of the Democratic National Convention.
 "It is widely accepted that greenhouse gas emissions are a major factor in
 global warming and that the amount of GHGs added to the atmosphere continues
 to rise," said Charlie Parker, president of Boston Carbon. "The DNC provides
 a great stage to raise awareness of this problem and our donation highlights
 the fact that for many companies, reducing greenhouse gas emissions and
 turning them into carbon credits is not only good for the environment, but
 also good for their bottom line."
 The credits donated by Boston Carbon to the DNC were created through the
 capture of fugitive methane gas from Jim Walter Resources, Inc., a coal mining
 company in Alabama. Methane gas is a particularly serious greenhouse gas
 since its global warming potential is twenty-one times that of carbon dioxide.
 The Boston Carbon project with Jim Walter Resources is believed to be one of
 the largest greenhouse gas mitigation project currently operating in the
 United States, capturing the equivalent of approximately 5 million tons per
 year of carbon dioxide which otherwise would escape into the atmosphere. The
 captured methane gas is, after cleaning, fed into an existing natural gas
 pipeline system for sale to natural gas users. The project is an excellent
 example of how, through skillful planning and execution, industry can move
 profitably to reduce the damage of greenhouse gases to the atmosphere.
 Boston Carbon's Pivotal Role
 Because the creation of credits from claimed reductions is not yet well
 understood, BCC has taken a leading role in creating the infrastructure to
 accelerate the process of earning credits in the United States. BCC serves
 both emitters -- who will need to make emission reductions -- and emerging
 innovators who will design and execute clean energy solutions. BCC has
 designed a comprehensive set of procedures to secure and monetize GHG emission
 credits for clean energy and power projects. The process includes preparing
 and submitting applications to qualified 3rd party approving bodies to secure
 approval, accreditation and certification of the credits. It also provides
 for monitoring, tracking, recording and registering of the reductions.
 Through its multi-disciplinary network of strategic partners, Boston Carbon
 provides a set of integrated, transparent procedures to ensure the validity of
 the carbon credits that are claimed.
 In the United States, although the federal government has been notably
 absent on this issue, bipartisan state actions are filling the void. For
 example, the Regional Greenhouse Gas Initiative, or RGGI, a cooperative effort
 by nine Northeastern and Mid-Atlantic states to reduce carbon dioxide
 emissions will set a regional limit for how much carbon dioxide electric power
 plants can produce and allow emitters who produce less than allowed to trade
 credits with those that exceed the cap. Other states and regions are working
 on similar plans.
 Based on the expectation that regulations to limit greenhouse gases will
 be coming soon, there is already a growing market in both Europe and the
 United States for GHG emissions credits. According to a study commissioned by
 the World Bank, approximately 64 million tons of reductions were traded during
 the first four months of 2004. The average price paid for pre-compliance
 project-based emission reductions in Europe was approximately $4.00 to $5.00
 per ton, while in the U.S, credits trade for approximately 95 cents a ton on
 the voluntary Chicago Climate Exchange.
 About Boston Carbon Corporation
 Boston Carbon Corporation (BCC), based in Carlisle, MA,
 ( ) is a leading consulting company advising
 clients on profitable environmental remediation techniques. Boston Carbon
 advises clients in the United States and worldwide on strategies to satisfy
 actual and impending regulations regarding the emission of greenhouse gases
 and other pollutants. BCC works with companies to identify clean energy
 projects, integrates of all the various steps necessary to maximize the value
 of greenhouse gas reductions as credits, thus increasing the project's overall
 economic value.

Polarity Reference Channels: PostgreSQL Error Codes cover image
Today's post continues an ongoing series on Polarity User Tips. Data tells a story, Polarity helps you see it with Augmented Reality overlaying contextual information as you work, giving you the right data at the right time to make informed decisions and take action with speed (no glasses or goggles required). This guide explains how you can see the story in your data with Polarity using the PostgreSQL Error Codes Reference Channel.
Intro to Polarity Reference Channels
Polarity Channels are a way to organize Entities and Annotations into logical groups, such as all of your assets or your LinkedIn contacts.
Reference channels are a Polarity Channel that is based on another source of information that is used just for reference purposes by Polarity Users. Reference channels can be anything from a list of internal or external threats to a list of assets to the PostgreSQL Error Codes list.
Where to find Reference Channels
On the Polarity Github page, download the PostgreSQL Error Codes reference channel or browse our library of reference channels for better data awareness and recall.
What are PostgreSQL Error Codes?
The PostgreSQL Error Codes is a list of codes that help database users troubleshoot what is happening within the database. The codes range from things that help with queries that are causing issues to errors that have occurred when the database crashes.
PostgreSQL Error Codes Reference Channels in Polarity
Based on the list that Postgres publishes, we have put together a CSV that you can easily upload into Polarity as a reference channel. The reference channel will instantly map the error codes that Postgres provides to what the error code is allowing you to easily correct what is happening.

Zydus Needle-Free Corona Vaccine Zycov-D: The World's First DNA-Based Vaccine
Zydus Cadila, a leading Indian pharmaceutical company, has developed the world's first needle-free COVID-19 vaccine, ZyCoV-D, which has recently received Emergency Use Authorization (EUA) from the Drug Controller General of India (DCGI) . The vaccine is built on a DNA platform and is administered using The PharmaJet®, a needle-free applicator that ensures painless intradermal vaccine delivery . This article provides an in-depth analysis of the Zydus needle-free corona vaccine, including its development, efficacy, administration, and safety.
Development of ZyCoV-D
ZyCoV-D is a three-dose vaccine that uses a plasmid DNA platform to produce the spike protein of the SARS-CoV-2 virus . The vaccine is designed to elicit an immune response against the spike protein, which is responsible for the virus's entry into human cells . The vaccine's development involved preclinical studies followed by clinical trials that included over 28,000 volunteers across India . The interim results of the clinical trials showed that the vaccine was safe and well-tolerated, with no serious adverse events reported . The vaccine also demonstrated an efficacy rate of 66.6% against symptomatic COVID-19 cases .
Efficacy of ZyCoV-D
The efficacy of ZyCoV-D has been a subject of debate since the vaccine's approval. While the vaccine's efficacy rate of 66.6% may seem lower than other COVID-19 vaccines, it is important to note that the vaccine was tested during the second wave of the pandemic in India, when the Delta variant was dominant . The vaccine's efficacy against the Delta variant is yet to be determined, but the company has stated that it expects the vaccine to be effective against the variant . Moreover, the vaccine has shown promising results in preventing severe disease and hospitalization, which are the primary goals of any COVID-19 vaccine .
Administration of ZyCoV-D
ZyCoV-D is administered using The PharmaJet®, a needle-free applicator that delivers the vaccine through the skin . The applicator uses a high-pressure stream of fluid to penetrate the skin's outer layer and deliver the vaccine into the intradermal tissue . The needle-free delivery system eliminates the need for needles and syringes, making the vaccine administration painless and reducing the risk of needle-stick injuries . The vaccine can be stored at 2-8°C, making it easier to transport and store than other COVID-19 vaccines that require ultra-cold storage .
Safety of ZyCoV-D
ZyCoV-D has been found to be safe and well-tolerated in clinical trials, with no serious adverse events reported . The vaccine's safety profile is expected to be similar to other DNA vaccines that have been approved for human use . However, as with any new vaccine, long-term safety data is yet to be established. The company has stated that it will continue to monitor the safety of the vaccine through post-marketing surveillance .
zycov d prons and cons
As with any vaccine, ZyCoV-D has its own set of pros and cons. Here are some of the potential advantages and disadvantages of this vaccine:
Needle-free delivery: ZyCoV-D is administered using a needle-free injector called the PharmaJet, which is a more comfortable option for individuals who are afraid of needles.
Efficacy: The clinical trials for ZyCoV-D have shown promising results in terms of efficacy. In a phase 3 clinical trial, the vaccine was found to be 66.6% effective against symptomatic COVID-19 cases.
Safety: The clinical trials have also shown that ZyCoV-D is generally safe and well-tolerated, with few side effects reported.
Production and distribution: ZyCoV-D is easier and less expensive to manufacture than some of the other COVID-19 vaccines, and it can be stored at normal refrigerator temperatures, which makes it easier to distribute.
Limited data: Although the clinical trials have shown promising results, there is still limited data available on the long-term safety and efficacy of ZyCoV-D.
Emergency use authorization: ZyCoV-D has been authorized for emergency use in India, but it has not yet been fully approved by regulatory agencies like the U.S. Food and Drug Administration (FDA).
Availability: ZyCoV-D is currently only available in India, and it may be difficult to obtain in other parts of the world.
Age restrictions: The vaccine has been authorized for use in individuals aged 12 years and above, which means it is not yet available for younger children.
It is important to discuss the potential benefits and risks of any vaccine with a healthcare provider to determine the best course of action for an individual's specific situation.
delivery or distribution of the Zydus Cadila's needle-free COVID-19 vaccine, ZyCoV-D.
ZyCoV-D is an indigenously developed DNA vaccine for COVID-19 that received emergency use authorization (EUA) from the Drug Controller General of India in August 2021. The vaccine is administered via a needle-free injector and is the first such vaccine to receive EUA in India.
Regarding the delivery or distribution of the vaccine, it is up to the Indian government and the vaccine manufacturer to decide on the distribution strategy. However, reports suggest that the vaccine will initially be supplied to the Indian government for its vaccination program and may be available in private hospitals and clinics at a later stage.
As for the coverage or number of people vaccinated with ZyCoV-D, there is no specific information available yet, as the vaccine has just received EUA and has not yet been widely distributed.


Montreal-based publisher Joseph John wanted his comic book "Citizen Canada" to reflect the country's diverse history by having the titular hero speak English, French and Cree.
But when he started entering the Indigenous superhero's dialogue into Google Translate he found that Cree, the most common First Nations language in Canada, is not an option on the app.
John then took it upon himself to create an online petition urging Google to make Cree available on its translation app. A user-experience designer by trade, the publisher said he wants to help preserve the Indigenous language.
"I'm not an activist, I'm just a... designer," said John. "Making comics has always been my passion (but) I want my comic to be especially helpful to Indigenous people, I want to help First Nations peoples."
The preamble to John's petition points out that Maori, the language of Aboriginal people in New Zealand, is available on Google Translate. New Zealand government data suggests there are approximately 50,000 Maori speakers there, but data from Statistics Canada's 2016 census shows there were more than 96,000 Cree speakers in Canada when information was gathered.
Simon Bird - the creator of Cree Simons Says, a Facebook group with more than 20,000 followers that teaches people how to speak the First Nations language - said he would welcome the addition of his native language to Google Translate as a tool for beginner or intermediate speakers.
"Once there's a common understanding of the language between a fluent speaker and someone that doesn't know the language at all, I think that's going to be the real benefit," said Bird, who is also the director of education for Lac La Ronge Indian Band in Saskatchewan.
Cree, part of the Algonquin language family, has nine dialects that are spoken in a vast geographic region that stretches from Labrador to Alberta and the Northwest Territories, according to figures from the territorial government.
Bird said although there are certain modern words that differ between the various Cree dialects, the heart of the language is the same across Canada.
Molly Morgan, a spokeswoman for Google, said that Cree is among the many Indigenous languages included in the company's Noto font project but added incorporating it into the Translate app is a more complicated process.
"We're gradually adding languages over time but our system needs lots of examples to learn from," said Morgan. "Unfortunately we don't have a timeline for that specific language. The process of adding a language to Translate takes a big concerted effort from contributors."
John, who emigrated from Bangalore, India, in 2007, said he hopes that his comic will help his fellow immigrants better understand First Nations people. He hopes that "Citizen Canada' will help them understand the difference between First Nations, Metis, and Inuit peoples.
"I don't want people to think of Indigenous people as tragic or victims or any of that, I want them to think of them as superheroes," said John.


fty} \frac{c_{\sigma_k}(\lambda)^2}{k} = 2vol(Y,\lambda).
The first item follows from Stokes' Theorem in the nondegenerate case; when \lambda is degenerate, the key result is a compactness result for pseudoholomorphic currents due to Taubes, see "From one Reeb orbit to two". The second item follows from the "volume conjecture" proved in "The asymptotics of embedded contact homology capacities".
We have now laid out all of the necessary machinery to give our proof.
Proof.
The nondegenerate case. Suppose we have exactly three embedded orbits.
Our manifold (Y,\lambda) must not be odd in view of Corollary 4. We will next show that we must have exactly two elliptic orbits. Choose \Gamma such that c_1(\xi) + 2PD(\Gamma) is torsion. If we had zero elliptic orbits, it follows from the definition of the ECH chain complex that ECH(Y,\lambda,\Gamma) would be finitely generated, contradicting (for example) Fact 3. Let \lbrace \sigma_k \rbrace be a U-sequence. If we had one elliptic orbit e_1 and two hyperbolic orbits h_1,h_2, we would contradict Fact 5. More precisely, the first bullet of Fact 5 together with Fact 2 would imply that \frac{c_{\sigma_k}(\lambda)^2}{k} would have to grow at least linearly with k, while the second bullet implies that this cannot occur.
Thus, we can assume that we have two elliptic orbits e_1,e_2 and a positive hyperbolic h.
[There can't be three elliptic orbits because this would contradict Theorem 1.2 in The Weinstein conjecture for stable Hamiltonian structures. -Ed.] The key fact is now that since c_1(\xi) is not torsion, \Gamma is also not torsion. The significance of this is as follows. We have an induced map \mathbb{Z}^2= \mathbb{Z}[e_1] \oplus \mathbb{Z}[e_2] \to H_1(Y), which sends [e_i] to the class represented by the Reeb orbit e_i. If the kernel has rank zero, then again, ECH(Y,\lambda,\Gamma) would be finitely generated. If the kernel has rank two, then these orbits would represent torsion classes in homology. On the other hand, by Fact 3, we must have a U-sequence in ECH(Y,\lambda,\Gamma) in even degree. This must take the form e_1^{m_k}e_2^{n_k}, contradicting our assumption that c_1(\xi) is non-torsion.
It remains to handle the case when the kernel has rank one. In this case, assume that the kernel is generated by some integer vector (c,d), say with d>0. Then each generator of our U-sequence e_1^{m_k}e_2^{n_k} must have the form e_1^{m_0+x_kc}e_2^{n_0+x_kd}. Because there are infinitely many distinct e_1^{m_k}e_2^{n_k}, we must have c\ge 0 (otherwise we would have -n_0\le x_k \le m_0 for all k). Since c and d are nonnegative, the asymptotics of this sequence would again violate the second bullet of Fact 5, since the action of each term in this sequence would have to be bigger than the action of the previous term by at least the minimum of the actions of e_1 and e_2.
The degenerate case. By "From one Reeb orbit to two", we have at least two distinct embedded Reeb orbits. So assume that we have exactly two, \gamma_1 and \gamma_2. We now argue similarly to before. Namely, again consider the U-sequence latex $\lbrace \sigma_k \rbrace$, as well as the induced map \mathbb{Z}^2= \mathbb{Z}[\gamma_1] \oplus \mathbb{Z}[\gamma_2] \to H_1(Y). By Fact 2, this kernel cannot have rank two. By Fact 2, and the first bullet point of Fact 5, the kernel does not have rank 0. By repeating the argument in the previous paragraph, it also cannot have rank 1.
QED
[Any ideas for improving the above bounds further? As suggested at the beginning, one might conjecture that if (Y,\lambda) is a closed contact three-manifold, and if Y is not (a sphere or) a lens space, then there are infinitely many Reeb orbits. -Ed.]

 Thanks for letting us post on your blog! I wanted to point out that one doesn't need Theorem 1.2 in your "Weinstein conjecture for stable Hamiltonian structures" paper to rule out the case of three elliptic orbits: you can instead use corollary 4 in this blog post.

The quality of education in infant and toddler centres
Early childhood education is a highly diverse sector that includes many different philosophies and approaches to the education and care of young children.
All ERO education reviews in the early childhood sector focus on the quality of education. For ERO this includes the quality of:
- the programme provided for children;
- the learning environment; and
- the interactions between children and adults.
In this report, ERO based its introductory statements and findings about the programme, learning environment and interactions on a set of evaluation indicators published by ERO4, references to provision for infants and toddlers in Te Whāriki, and signposts and explanations of the Revised Statement of Desirable Objectives and Practices (DOPs) published by the Ministry of Education.5

WINDSOR – It was billed as a 'Star Party', but Mother Nature didn't quite cooperate.
A trio of science-oriented groups: A Time for Science (ATFS), North Carolina Land of Water (NC LOW), and the Coastal Studies Institute (CSI) partnered to host the event Thursday evening at the Bertie County Middle School Gymnasium.
The group receives funding from several sources, including Bertie County and the Town of Windsor.
Outdoors, the youngsters were going to view the panorama of the skies – best seen during the phase of a new moon – but beginning around evening time (6:30 p.m.), cloud-cover began forming across the southern part of the county, and only thickened as the night wore on.
Undaunted, ATFS had brought along a mobile Planetarium for star-gazing; and while it didn't take the place of looking at the actual moon, nor The Milky Way, Orion, or Cereus Major, it did provide the youngsters and their parents with an education on the wonders of the night-time.
"This free event is an excellent opportunity for the public to engage with the nocturnal environment in a new way with expert guidance and observational resources," commented retired East Carolina University research professor, Dr. Stanley Riggs, one of the night's organizers.
"We've been doing these teacher-science education workshops all year," said Riggs. "It's part of bringing science to the students and to teach everyone what's in your own back yard in the earth, the water, and the skies. We deal with landscapes, waterscapes, and skyscapes."
Science teachers from Bertie County elementary schools and Bertie Middle School were on hand with the students, and were glad it was an evening that emphasized STEM (Science, Technology, Engineering and Math).
"The greatest thing for these kids is the exposure," said Cheryl Jefferson, a Science, Reading, and Social Studies teacher at West Bertie Elementary. "It's also showing them that they have options in STEM professions; since kids these days want jobs where they can be successful and make money. STEM is trending nowadays and they are learning that we would all be lost without it."
Riggs said the skies of northeastern North Carolina from the Roanoke River to the coast are the darkest on the eastern United States coast between Boston and Miami.
"There's not a whole lot of night sky left in the world because we have lights everywhere," he observed. "One part of this is educating people about 'light pollution', and how we can keep our dark skies."
Ashley Bradley, an 8th grade Science teacher at Bertie Middle School, said expanding her students' perspective is very important nowadays.
"The goal of these exhibits is to teach kids to expand their knowledge in some of the under-represented areas of science," she explained. "We want to also make them aware of other sciences."
One of the evening's most popular presentations, especially in lieu of no outdoor star-gazing, was the indoor, interactive planetarium with showings led by astronomer Brian Baker every half hour.
Baker studied astrophysics at Florida State University and has been teaching people of all ages about the wonders of the night sky for 11 years. He's currently the astronomy and space science director at ATFS in Greenville. He says the group travels for outreach events within the area, making a Star Party a rare treat for the Bertie County public.
"The Star Party is usually held during a new moon, which is the optimal time to observe the night sky," Baker said. "Unfortunately, tonight, we couldn't. Students will see the stars like they've never seen them before."
Mike Littleton, one of the members of the Coastal Studies Institute and a retired physicist and astronomer brought along several telescopes, and one other vital item for observing the night sky.
"A pair of binoculars," he joked, holding them aloft. "If you ever tire of looking at stars, moons, and constellations, you can always use them for bird-watching. But, seriously, they're a great and inexpensive nighttime tool."
"Folks can use our telescopes or even bring their own to receive guidance on how to use them, which can sometimes be intimidating," he noted.
Other children's activities and exhibits included making a Star Wheel, a paper device the children could take home and later use to observe the cosmos and read the night skies when the clouds are more cooperative.
"I never taught high school, or elementary school for that matter," conceded Riggs. "But this is all a part of what eastern North Carolina needs. We have such a wealth of natural and cultural resources here and we need to learn how to understand them, and then use them creatively to produce jobs. Ecotourism is a future that can hopefully make Bertie County so much richer and so much better."

While recent Timed-Release Encryption (TRE) schemes are implicitly supported by a CertificateLess Encryption (CLE) mechanism, the security models of CLE and TRE differ and there is no generic transformation from a CLE to a TRE. This paper gives a generalized model for CLE that fulfills the requirements of TRE. This model is secure against adversaries with adaptive trapdoor extraction capabilities for arbitrary identifiers, decryption capabilities for arbitrary public keys, and partial decryption capabilities. It also supports hierarchical identifiers. The authors propose a concrete scheme under their generalized model and prove it secure without random oracles, yielding the first strongly-secure smcle and the first TRE in the standard model.

Duolingo's Bilingual True Crime Podcast Helps Makes it Fun to Learn Spanish
Duolingo's true crime podcast El Gran Robo Argentino preview with bulletin board full of photos and notes
If you've ever talked to someone who spent time living in another country, you probably heard them say they really started to pick up the local language by jumping in and engaging with native speakers. That's exactly why Duolingo decided to launch its new bilingual true crime podcast, El Gran Robo Argentino.
This serialized season actually marks a decisive new turn for Duolingo's Spanish podcast, which has been around since 2017. Now, with El Gran Robo Argentino (or, The Great Argentine Heist), language learners can experience some immersive language-learning experiences of their own. The serialized podcast will span six episodes, and is narrated by bilingual podcast host and producer Martina Castro.
The Spanish-for-English-speakers podcast tells the story of one of the greatest bank robberies in Latin American history. In it, learners will be able to listen to interviews from actual people involved in the Buenos Aires robbery, including investigators, journalists, and even one of the actual bank robbers.
El Gran Robo Argentino includes native speakers telling their stories in easy-to-understand Spanish, alongside Castro, who deftly weaves between Spanish and English to help listeners follow along. The podcast launched on October 22, and you can listen to it wherever you prefer to listen to podcasts.

What's the difference between a glass break sensor and a window sensor?
Last Updated: 11/07/2013
A window sensor, like the 5811BR, works in a similar way to a door sensor. It has an internal reed switch, a magnet, and a contact. The magnet and reed switch are close together when the window is closed. An opened window separates the two which triggers an alarm. A window sensor only sounds an alarm when a window is opened.
But what if the window is broken?
That's where the Honeywell Glassbreak Detector comes in. Glassbreak detectors are equipped with audio microphones that detect the sound frequency of broken glass. These sensors are typically mounted on the wall opposite a window, and if an intruder should break the glass, the alarm will trigger.
Shock sensors work like preemptive glassbreak sensors. They can sense when window glass is vibrating at a rate consistent with someone trying to forcibly break the glass. This sensor triggers an alarm before a window is even broken, which deters an intruder even before entry, and saves you the cost of having to replace a broken window.

|SubTree (RAM construct)||Hive (File)|
|HKEY_Local_Machine\HARDWARE||dynamically constructed at boot by NTDETECT|
The files on the disk are called the HIVES. The corresponding registry memory constructs are also often called hives but are best referred to as subtrees. The trees are HKEY_LOCAL_MACHINE and HKEY_USERS. The subtrees are constructed from the hive files (except for the HARDWARE subtree which is generated by ntdetect.com during boot). After boot the hive files and matching subtrees are only logically insynch. When the SECURITY subtree was constructed by reading the SECURITY hive file, they were identical. Any change to a subtree is recorded in the subtree.log file. At any point the correct registry subtree can be constructed by reading the hive file and then applying the changes in the corresponding hive log file, for example, SECURITY and SECURITY.LOG files. The.ALT files are an additional copy of the.LOG file and is used to construct the subtree if the.LOG file is corrupt. The registry maintains a current mapping of which hive files were used to generate the subtree. This registry value is the definitive hive list. Its found at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\hivelist.

While farm and ranch are distinct words in the agricultural industry, many people often use the terms interchangeably when saying them. It's understandable as they both deal with big acres of land and play a vital role in bringing food to our local grocery stores.
Understanding the differences between farmland and ranchland will help when determining what type of owner-financed lot you need in East Texas. Let's put any confusion about what is a farm and what is a ranch to rest so that you are aware of their respective differences, especially if you want to work in the agricultural sector.
The Distinction of Farm and Ranch
The difference between a farm and a ranch is their primary use. The primary function of a farm is to grow an assortment of food, raw material, or fuels. For example, many dairy farms produce crops, so fertile, healthy soil is important for its production needs. Most farms are large in size, and their product is produced by an animal such as cattle.
dating-of-fitness reviews – BANG winstrol oral cycle apuan traders between crisis and recovery. interview with lorenzo tabaracci from carrara, of the diet & fitness supplement store | the site of massa carrara
However, ranches are used for a specific farm function such as raising livestock (e.g. sheep, cattle, goats, and pigs to name a few). In fact, a rancher's chief concern for their livestock is having a lot of land for grazing, so they will need to accommodate for that.
Further distinction between the two include:
- Calls his land fields.
- Barn is filled with equipment.
- Concerned with water, growth, and prices of their crops.
- Want straight rows and strong crops.
- Calls his land pastures.
- Cattle are found in the barn.
- Concerned with the health of livestock, feed prices, and the value of their cattle.
- Want plentiful grass and healthy, robust cattle.
They Do Share Similarities
Other than these distinct differences, the reasons the terms farm and land are often viewed as interchangeable is because of their similarities. Chief among them, however, is their use of cattle.
Both ranchers and farmers have big plots of land, but a ranch is usually bigger than a farm. This is because ranches have cattle for the purposes of producing meat and dairy products that are shipped out and purchased at grocery stores or served in a restaurant.
Additionally, farmers often provide feed to their cattle while ranchers rely on their land for sustenance. Ranchers spend a lot of time checking their livestock, fixing their equipment, and getting water to their animals; dairy farmers rely on producing milk throughout the year and an ongoing supply of other dairy products while cattle ranchers go to market to sell their cattle–which are bigger than dairy cattle–once a year.
An investment on owner-financed land for ranching or farming purposes requires skill, dedication, and hard work in order to generate income off your land. Finding the right owner-financed lot in East Texas is something Santa Cruz Properties has done for many farmers and ranchers throughout the years, so you know your family's future is in good hands.
