The design of minimum-length test sequences for pattern sensitivity in random-access memory (RAM) arrays is examined. The single pattern-sensitive fault (SPSF) model is used in which operations addressed to at most one memory cell are allowed to be faulty at any time. The influence of an SPSF affecting cell Ci is restricted to a fixed set of cells called the neighborhood of Ci. A new method is presented for efficiently generating the sequence of writes required in an SPSF test. This method yields optimal sequences for a useful class of neighborhoods called tiling neighborhoods. It is observed that RAM neighborhoods can be interpreted as polyominoes. A general procedure is given for constructing an SPSF test containing the minimum number of writes but a nonminimum number of reads. The difficult problem of minimizing the number of reads in an SPSF test is investigated for the 2-cell memory M2. A test of length 36 for M2 is derived which is optimal under certain reasonable restrictions. It is demonstrated that minimum-length SPSF tests can be inherently asymmetric.

A primary caregiver is a person responsible for the care of another person or child as defined by the law. In custody agreements or orders, the primary caregiver is the person the child lives with majority of the time.Continue Reading
The primary caregiver is the person who assumes responsibility for the health, safety and housing of another adult or child. For example, when an elderly person is incapacitated due to illness, a primary caregiver provides assistance with feeding, bathing and changing and may even handle finances when mental deficiencies exist. In some cases, the primary caregiver is also designated as power of attorney for the individual. When people reside in nursing homes or rehabilitation centers, the medical staff serve as the primary caregivers.
When illness strikes, primary caregivers often perform medical and therapeutic tasks for patients and operate as personal advocates and home-based care coordinators. In many cases, family members often serve as the primary caregiver offering both physical and moral support for ailing individuals.
In custody agreements, a parent labeled as the primary caregiver does not receive any extra authority or decision-making power than the other parent beyond day-to-day activities and decisions. However, the child or children live with the primary caregiver majority of the time and use the residence as a permanent address.Learn more about Career Aspirations

Soccer science and the Bayes community: exploring the cognitive implications of modern scientific communication
Science is a form of distributed analysis involving both individual work that produces new knowledge, and collaborative work to exchange information with the larger community. There are many particular ways in which individual and community can interact in science, and it is difficult to assess how efficient these are, and what the best way might be to support them. This paper reports on a series of experiments in this area, and a prototype implementation using a research platform called CACHE. CACHE both supports experimentation with different structures of interaction between individual and community cognition, and serves as a prototype for computational support for those structures. We particularly focus on CACHE-BC, the Bayes Community version of CACHE, within which the community can break up analytical tasks into "mind-sized" units, and use provenance tracking to keep track of the relationship between these units.

How Did Sylvia Plath Die?
Sylvia Plath was a child prodigy, and she was a perfect child and student. She was praised by everyone for her perfectionist nature; as she did everything right from the word go. When she was eight years old, her father died. This left Sylvia quite sad and also she developed suicidal tendencies later in her life.
She attempted to commit suicide when she was in junior college by taking seeping pills and overdosing on them. However, she survived that incident.
Plath ended her life when she was only thirty years old. She locked herself in a room with her children in another room. Plath put her head into the oven and turned on the gas. The next morning she was declared dead. However, it was comprehended that Plath really did not intend on killing herself or never thought she would succeed. Also, she asked her neighbor Mr. Thomas at what time he would be leaving the next morning. She also left a note that was a reminder to call Dr. Horder and even had his phone number written down. The next morning the baby sitter could not get into the apartment and had a workman help her get in. It is then that the baby sitter and the handyman found Plath. Her head was still inside the oven.
However, in her biography it was written that she pushed her head deep into the oven and she had all intentions of killing herself. Also, there were claims that her husband was abusive towards Plath. The exact reasons for her suicide were never known even to her good friends.

The aim of this study was to determine if infrared thermography can be used as a tool to detect jugular venipuncture in the horse to support United States Equestrian Federation drug administration rule enforcement. This is a blinded, randomized clinical trial, and eight adult Thoroughbreds were used. For each horse, thermographic images of both jugular grooves were obtained by a blinded examiner, prior and subsequent to jugular venipuncture (10-mL sterile saline). Injected sides were randomized, and images were acquired before injection and then 0.5 hours, 1 hour, 2 hours, 3 hours, 6 hours, 12 hours, 24 hours, and 36 hours after injection. Horses were maintained in a temperature-regulated stall. Images were reviewed and analyzed with standard thermography software to determine if venipuncture could be detected. Images of treated sites were minimally visibly different from those obtained at baseline or for the control sites. Following image analysis, a significant reduction (P <.05) was identified when mean jugular groove injection site temperature measurements were compared to baseline mean temperature measurements. The greatest observed difference (1.4 ± 0.8°C) was identified at 2 hours after injection. At time points 0.5 hours, 6 hours, and 12 hours, delta T (difference between the mean temperature at each time point and the baseline temperature) was significantly different between the jugular injection site and the control site. Infrared thermography detects a significant change in surface skin temperature from baseline following jugular venipuncture for sterile saline injection. No significant comparable observed changes were identified at the control sites.

Robert A. was visiting Chicago a few weeks ago and discovered something very interesting. He was sightseeing inside the ornate Chicago Cultural Center and noticed this frieze on the ceiling:
This is the Grand Army of the Republic Rotunda. Taking a closer look at the corner:
Here's a sharp photo someone else took of the Don't Tread on Me frieze.
Is that neat, or what?
Robert and I are intrigued and want to learn more. I've never seen this combination of symbols before. Was it some flourish of the architect? Did the designer make it up, or reproduce it from somewhere?
The Chicago Cultural Center was opened in 1893. It was originally a dual-purpose building: a Chicago public library, and a museum/meeting hall for the Grand Army of the Republic veterans association.
Robert found a booklet entitled "The People's Palace: The Story of the Chicago Cultural Center" which briefly mentions the rotunda:
"At the top of the stairway is the 45-foot by 50-foot Grand Army of the Republic (G.A.R.) Rotunda. The ceiling is embossed with plaster carvings of swords, shields, helmets, and flags. This ornamental heraldry serves to remind viewers of the loss that comes with war."
That's not much, and sounds a little bit like politically-correct pap to me. How does that frieze symbolize the loss that comes with war?
I find it interesting that these symbols aren't from the Civil War. They're from the American Revolution: the Liberty Cap, the Liberty Tree, and our Don't Tread on Me snakes. To the degree that DTOM symbols were used in the Civil War, it's my understanding that they were used by the South, not the North. This dome and hall were funded and used by the GAR, i.e. Union veterans.
Does anyone have insights?

08: Is it possible to "TrunkTrack" without a TrunkTracker?
 It didn't used to be, but times do change and YES! It is
 now possible to track the trunks without a 'real'
 TrunkTracker Scanner, and better, for that matter!!!
 Like the other subjects in this FAQ, it all begins with
 a Data Decoder Interface. See Q&A #4 and Note 10 in that
 answer for the tiny extra addition you need to make to
 the Decoder Interface.
 Next, you need a PRO-2004, PRO-2005, or PRO-2006
 scanner, although we hope to add other scanners to the
 list in due time. For now, it's one of those three.
 NOTE: It is possible to track the trunks with a
 AR-8000 and perhaps with one of the Opto
 Interfaces, but these are specialized situations
 where detailed info must be found elsewhere.
 Then you need a CE-232 Scanner/Computer Interface (or
 its predecessor, the HB-232). You will also need the
 hot, new Windows program for the CE/HB-232 called
 Pro-Turbo.
 Lastly, you need one fairly modern computer, Pentium 133
 or better, for the easiest way to track the trunks, but
 there is another way almost as easy, if you have two
 computers, one a 486DX2/66 or better and the other, a
 PC-386 or better.
 There are other requirements, too, but the above are the
 main ones. It is beyond the scope of this FAQ to spell
 out all the details, but the V8N9 issue of the monthly
 World Scanner Report tells it all. You can order this
 or any other back issue of the World Scanner Report
 since Jan-91, including 6-mo and 1-yr subscriptions.
 You can also download a more detailed text file on
 TrunkFollowing with the PRO-2004/5/6 from my FTP site at:
 _URL_
 For more information on the Pro-Turbo software for the
 HB/CE-232, contact:
 Paul E. Turton
 RR # 3; Wainfleet, Ontario Canada L0S 1V0
 E-mail: _EMAIL_ or _EMAIL_
 Web: _URL_
 For more information on the CE-232 Interface, you can
 download a file called PRODINFO.ZIP from:
 _URL_
 or you can view and download all the individual files
 from the \CE-232 directory. Or, you can ask for it as
 an e-mail file attachment from: _EMAIL_
 or see the information in my signature box below.
 But yes, it is now possible to track the trunks without
 a TrunkTracker scanner, and do it better than any of the
 "real" TrunkTracker scanners! The cost can be a lot
 less than the cost of a real TrunkTracker, too. The cost
 largely depends on what you already have, or can
 scrounge up, but at worst, it's well within the budget
 of many scannists.

Parasitic worms can trigger a specific immune response that counteracts rheumatoid arthritis in mice, a study in Nature Communications reveals.
The researchers from Germany infected mice with the parasitic worms (Nippostrongylus brasiliensis) and compared them with control groups.
They discovered that the worm infections activated a Th2 immune response that protected the mice from arthritis.
According to the authors their findings provide "solid evidence" that activation of the Th2 responses by N. brasiliensis infection counteracts arthritis.
"Mechanistically, this protective effect is dependent on IL-4/IL-13-induced STAT6 pathway" they wrote.
The authors also found that the cellular components of the Th2 responses and eosinophils were present in the synovial membrane of people with RA.
This finding suggested that even in the absence of worm infection these responses were already engaged in suppressing the pathology.
"These findings are interesting to shape new approaches to rebalance immune homeostasis in arthritis," they said.
Previous data had shown a Th2 cytokine pattern in very early forms of human RA, when the disease may still be reversible, they noted.
"Activation of Th2 responses and eosinophils in both early and established disease may emerge as a new strategy to treat arthritis," they concluded.

I wrote the following article for creating Shadow Walls for Children's museums. However, they are very effective at home haunts as well. So I thought I would share it here:
A shadow wall, also known as a Silhouette Wall, is a phosphorescent wall used with a timed light source to capture and display children's shadows.
Children pose in front of the wall while a light flashes creating a black shadow on a green glowing wall. This allows the kids to turn around and see their shadow. The shadow fades, allowing another child to take a turn.
Shadow walls are popular in childrens museums and other indoor play areas. However, they can also be made inexpensively for birthday parties.
This article will give advice for creating each component in a professional manner and lower cost hobbyist alternatives.
Phosphorescent paint comes in many varieties, most of which are designed to maintain their glow for a long time. Shadow walls are unique in that they require a paint that is relatively bright, charges very quickly, and decays very quickly. To meet these criteria, Glow Inc. designed a custom mix called the Shadow Wall
Formula. While meeting the above requirements, it is also designed to resist the damage caused by kids touching it. It applies easily with nominal smell and no fumes.
You will need 1 quart of Shadow Wall Formula per 4' x 8' sheet.
The wall's structure can be created using sheet materials like drywall, wood, vinyl, plastic, or glass.
The best materials are clear, such as glass or clear acrylic (Plexi-glass). If using glass, make sure that it is thick enough that it can not be broken by excited children. Clear acrylic is a lower cost, easier to use material. However, clear acrylic scratches easy and requires some maintenance.
For clear wall materials, we suggest you paint the rear side of the clear sheet with several layers of Shadow Wall Formula and then a layer of standard acrylic fluorescent white paint. Allow to dry between layers. Then hang or glue the glass to the wall with the painted side facing the wall. While costly, this creates a very smooth, professional appearance.
For opaque materials like wood, vinyl, plastic, and drywall, prepare and prime the surface as you would for any other water-based paint. Add a several layers of Shadow Wall Formula, allowing it to dry between layers.
For a cheaper alternative, my personal preference is corrugated plastic (Coroplast). It can be acquired at most sign shops for under $20 for a 4'x8' sheet. If you go this route, get white and do not prime it before adding the glow paint. It can be cut into manageable sheets for storage and weighs very little, making it ideal for temporary installations like parties.
A common mistake is to have too much ambient light in the room. If you want a bright shadow wall and high contrast shadows, then you need to keep the room just above pitch dark. The room would ideally be painted flat black and no light source would directly shine on the shadow wall. This includes light from other rooms when the door or curtain is open.
Red light will increase the discharge speed of glow pigments used in the Shadow Wall Formula. This can be used to your advantage in professional installations to provide light for entrance and exit while also quickly clearing the wall for the next child. While any red light will work, I personally suggest red LED par cans.
Children waiting in the queue should be in a dimly lit room so their eyes have a chance to dark adjust, preferably for 5 or more minutes.
The light to charge the shadow wall should emit as much ultra-violet light as possible, preferably with nominal visible light.
Visible light adjusts the children's eyes for daylight and the glow will therefore appear less bright.
That being said, disposable cameras with flash are an effective charging light for shadow walls used at kid's birthday parties. They can typically be acquired for free by asking nicely anywhere that processes film. Strobe lights are another inexpensive alternative. If you use these visible light alternatives, consider telling the children to close their eyes for the flash.
For professional installations, use only ultra violet lights, also known as black lights. For crisp edges on your shadows, use a light with a single point of origin like a bulb. Tube or LED black lights have a wider origin, which will blur the edges of the shadow. Black light bulbs sold for parties that look similar to regular screw-in light bulbs perform very poorly.
Therefore, I suggest a high powered "cannon" or stage fixture like Chauvet's Black Shadow 400w Blacklight. You can use the light's spec sheet to determine its beam angle. With this angle, you can determine how far back to mount the light for optimum performance.
I suggest you mount the light 1-2 feet from the floor. This low aspect will make most shadows taller than the children while keeping their feet in frame.
Using your timer, adjust the "flash" time for optimum performance. Longer flashes create a brighter glow. However, longer flashes also blur the edges of the shadow as children move.
For home use, the timer is a human pushing a button.
For professional installations, you will definitely want to add an automated timer. This can be accomplished hundreds of ways. I personally use a computer, Enttec DMX USB Pro, Chauvet DMX-4 Relay/Dimmer, and Vixen software.
Here is a typical Timer sequence started by human trigger:
00.0s Countdown clock 5
01.0s Countdown clock 4
02.0s Countdown clock 3
03.0s Countdown clock 2
04.0s Countdown clock 1
04.9s Red light turns off
05.0s Ultraviolet light turns on
05.5s Ultraviolet light turns off
(Note: this is when the wall glows)
30.0s Red light turns on

Human-Machine Interactions in Pricing: Evidence from Two Large-Scale Field Experiments
34 Pages Posted: 12 Apr 2024
Date Written: March 18, 2024
While many companies use algorithms to optimize their pricing, additional human oversight and price interventions are widespread. Human intervention can correct algorithmic flaws and introduce private information into the pricing process, but it may also be based on less sophisticated pricing strategies or suffer from behavioral biases. Using fine-grained data from one of Europe's largest e-commerce companies, we examine the impact of human intervention on the company's commercial performance in two field experiments with around 700,000 products. We show that sizeable heterogeneity exists and present evidence of interventions that harmed commercial performance and interventions that improved firm outcomes. We show that the quality of human interventions can be predicted with algorithmic tools, which allows us to exploit expert knowledge while blocking inefficient interventions.

Tunkin Depression
"The Tunkin Depression volcanic field (also known as the Tunka Depression) covers a broad area immediately west of the SW tip of Lake Baikal. The Khobok group of basaltic cinder cones near the village of Tunka, one of five groups of cinder cones characterized by some sources as late-Pleistocene to Holocene in age, has the largest concentration of vents. Drill cores show that the upper 500 m of the basin is filled with Quaternary tuffs and a dozen lava flows; subsidence continues, partially burying volcanic features. Other well-preserved cinder cones of probable Pleistocene age are located to the SE in the Khamar-Dayan Range. The youngest cinder cones and lava flows are in the NE part of the Tunkin Depression. The age of the latest eruptions has variously been considered to be Pleistocene-to-Holocene or late-Pleistocene." -Smithsonian Volcano Archive

Ceiling Cables
Here's How You Can Hide Wires in an Exposed Ceiling
You're thinking of building a house with an exposed ceiling or maybe you already live in one. Either way, you realized the wires on the ceiling aren't exactly pretty or safe to look at. So, you're trying to learn how to hide the wires in your exposed ceiling.
To hide wires in an exposed ceiling, you'll need creativity. You'll also need some knowledge of safety concealing the wires to ensure it won't eventually cause any accidents. One way to hide wires in an exposed ceiling is by pinning them in place and painting them the same color as your ceiling.
This article will talk about how you can hide wires in an exposed ceiling. It will also discuss the trend of exposed ceilings and the types of exposed ceilings.
Hiding Wires in an Exposed Ceiling
Exposed ceilings give your house a rustic look when done right, and it also saves you some money. Without needing to spend on materials and labor to cover your ceiling, you can use that money to hide the wires instead and buy other things to enhance your house.
However, you need to keep in mind that your wires need to follow safety precautions to ensure they won't cause any accidents even when hidden. This means your wires should not be bare or open. They also need to rest in places that won't get wet or constant exposure to the elements. If they receive constant elemental exposure, they will easily wear out, and you will need to replace them.
To hide wires in an exposed ceiling, the first thing you need to do is ensure that they are attached to the beams. You can do this by using electrical staples like Gardner Bender metal staples on Amazon. Once all the wires are secured, you can start to creatively hide them by painting them or using cord covers, wooden mounds, or decorative boxes.
You Can Paint the Wires on the Ceiling
If you're bothered by your ceiling wires poking out in an exposed ceiling, one option is to paint the wires. This boosts your house's aesthetics without consuming too much money or time. To do this, all you need to do is buy paint that matches your ceiling beam's color. This camouflages your wires and keeps a simple ceiling.
You may also paint the ceiling beams themselves if you can't find the shade that matches the beams. You can find paint in your local hardware store or on Amazon. An excellent paint find is Majic Paints, which can coat many surfaces. You'll notice that most people opt for a white painted ceiling or wooden-colored wires, but you may pick other colors from Majic Paints.
The advantage of painting your ceiling wires or even ceiling beams is that you can choose a uniform color for your ceiling or design it. However, some disadvantages include paint expense and labor fees if you hire someone to do it. There's also a chance that you won't like the outcome.
You Can Use Cord Covers for the Ceiling Wires
If you don't want to paint but still want an easy fix for your exposed ceiling wires, check out some cord covers. You can easily find them on Amazon, and among the general public's favorites are Cord Cover Raceway Kit, Paintable Cord Concealer, and Cordinate Fabric Cord Cover.
Cord Cover Raceway and Paintable Cord Concealer both come as white sets of cord covers. You can paint them however you want to match your decor, or you can keep them that way for an accented look on your ceiling beams if the beams aren't white. Meanwhile, Coordinate Fabric Cord Cover adds an aesthetic look to your house. You can choose to either make them camouflage themselves or have them stand out on their own.
If you choose the hard covers, you can place your wires within them by measuring the length you need and cutting the covers accordingly. Then, slide the cover open and simply place the wires inside the covers before sliding them closed again.
If you use the fabric cover, you'll have better flexibility, which may or may not benefit you, depending on your design idea. You can simply allow the fabric wire covers to hang on the ceiling beams, or you can pin them in place for better security and more organization.
Using cord covers can efficiently and cheaply cover up those exposed ceiling wires. You can easily replace the covers, too, when you get tired of their color or design and pick new ones. Best of all, you can customize the covers themselves to however you want them.
You Can Opt For Wooden Moldings to Hide the Wires
For a more classic look and better camouflaging, you can opt for wooden moldings to hide ceiling wires. You can find wooden moldings in hardware stores, or you can make them yourself. These moldings can act as ceiling beam borders, and no one would know they hide wires.
They're great alternatives if you don't want to use plastic or fabric covers. However, they can cost more than buying covers and require more work. You'll need to attach the wooden moldings to the ceiling beams, and that would take time and some hard work. You can't easily change the moldings, too, if you come across a point where you want to.
You Can Use Decorative Boxes for Grouped Wires
Decorative boxes work great in covering exposed ceiling wires in groups. You can create a standard square box that will match your ceiling beams, or you can purchase cover plates like Arlington Boxes or Garvin Hole Cover on Amazon. Grouped wires are perfect for ceiling fans and light wires, but you may find that they look good even in places without grouped wires.
When Did the Trend of Exposed Ceilings Start?
Houses with exposed ceilings existed and had been the trend until the 1800s when lumber mills started producing wooden structures by the bulk. By the 1950s, people covered ceilings. By this time, the trend of the exposed ceilings faded, and clean, hidden ceilings were the new ideal.
However, with plenty of options now, such as faux exposed ceilings or even exposing previously hidden ceilings, the trend of exposed ceilings restarted once more by the early 2000s. Two types of exposed ceilings exist: decorative exposed ceilings and actual exposed ceilings.
Actual exposed ceilings rely on the beams to support the house, and no other material covers the ceilings. Meanwhile, decorative ceilings are just as they're called: decorative. You'll find that these houses already possess a covered ceiling and simply have additional beams to make it look like an exposed ceiling.
Some people create the exposed ceiling look themselves, but it's not quite recommended since most people use heavy beams that may cause strain on their ceiling. Meanwhile, others use lighter materials like fiberglass or plastic, and some people contact engineers or architects for advice.
Final Thoughts
You can hide wires in an exposed ceiling by painting the wires or your ceiling beams or using plastic or fabric cord covers, wooden molds, or decorative boxes. However, make sure your wires are safely in place to avoid any accidents.
You can do this by pinning them in place, except when you're using fabric covers. You can get away with not pinning your wires in that case. Also, remember not to hesitate if you think you need help. Commencing on a do-it-yourself project is great, but ensuring your safety should remain your priority.

Are Paper Checks Still Relevant?
Are Paper Checks Still Relevant?
With the rise of debit cards, paper checks can seem slow and outdated. After all, checks work much like a debit card, allowing the recipient to redeem the check for the stated amount, although the actual transfer of funds can take longer. While there is an argument that paper checks are no longer relevant or useful, they are still in use, primarily by adults over the age of 55, with checks accounting for 15 percent of all non-cash payments in one of the latest studies reported by the Federal Reserve. Checks are still heavily used for large money transactions, such as payroll and rent.
Here's a brief look at the benefits and drawbacks of paper checks and why they still have a place in today's online-dominated marketplace.
Pros of Paper Checks
No payment solution is best for every situation. For example, debit and credit cards, while convenient, can come with a higher risk of identity theft and higher costs for merchants. The following are the most important benefits that paper checks can offer.
 - Many businesses do not accept cards. Credit card processing can be expensive and not every business can afford this cost. Forbes reports that 55 percent of the 27 million small businesses in the U.S. do not accept credit cards. That is especially true with micro-merchants, such as landscapers and pool cleaners, who do not have the volume to justify payment processing costs. With some bills such as rent to a landlord, a check is the only way to make a payment.
 - Easy person-to-person payments. There are now many ways to send money to a private individual, such as Square and PayPal. Despite their convenience, there is not a single payment option that dominates the others. A personal check offers a convenient and accessible way to pay a private individual who does not need to do anything special to receive the money.
 - Check use creates a paper trail. When you use a check, it automatically creates a paper trail that documents when proof of payment was received. Checks are the best way to prove that a lender, creditor, or government agency received payment.
 - Checks can be post-dated. A check works like a contract, stating that the person the check is written out to is to be paid the specified amount on the date noted on the check. Post-dating a check can work for both parties. The person who writes the check knows it cannot be cashed before a specific date.
 - Payment can be stopped. While some banks charge a fee of up to $35, you can stop payment on a check. That is not an option with other payment methods.
Cons of Paper Checks
There are many reasons that paper checks remain relevant, but they are not without drawbacks.
 - Overdraft potential. One of the primary disadvantages is it can be easy to overdraft an account without careful balancing of your checkbook. If you bounce a check, you can face a fee from your bank as well as the check recipient.
 - Merchants do not always take checks. It can be harder to find merchants who are willing to accept checks today, especially out-of-state checks or checks from unfamiliar banks. Merchants also face risks by accepting checks. It may be days before the merchant is alerted that the check was fraudulent or that the check was rejected due to insufficient funds.
 - Security concerns with some checks. There can also be security issues with personal checks. When you give someone a check, you are providing them with your account number, name, and contact information on the check. A check payment can also be used to begin electronic debits which give the merchant greater access to the payee's bank account to make unauthorized but legal debits.
The days of paper checks dominating the payment landscape are gone, but paper checks are still relevant. Check payments offer benefits not available with other payment options, including the ability to post-date a payment, stop a payment, and create an easily traced paper trail for recordkeeping.

An exploratory study of Nantou Ancient Village revitalisation focusing on visual, cognitive and structural aspects
MetadataShow full item record
In the absence of spatial diversity, there is a need for additional elements that will enable the recognition of the space in which we are. These elements are landmarks. In order for a certain thing to be considered a landmark, it must be unique and recognisable either by its properties (size, shape, colour, materialisation, etc.) or by the location where it is located in space. Landmarks and zones with a strong character provide a strong identification of the space with its peculiarity. This paper analyses the identity of the urban settlement of Nantou Old Town as a historical cluster located in the attractive location in the Nanshan District of Shenzhen City, with over 800 residential and commercial units. The study was conducted experimentally on a number of respondents who are regular or occasional consumers in Nantou settlement, through a closed questionnaire, from which we got answers to the initial questions: how successful is the revitalisation of this cultural-historical settlement, what are the landmarks, how simple is orientation through the settlement and what method is most common in wayfinding (landmark or navigation app), does a consumer's choice in wayfinding device and landmark physical characteristics (colour, texture and form) depend on personal dimensions (gender, age, educational level and familiarity with environment).

|Korcula.NET > Places on the island - Korcula - Moreška dance|
|THE MORESKA DANCE
Moreska is pronounced 'Moreska'. It means 'Moorish'. The word is derived from the Spanish adjective 'Morisco' or the Italian 'Moresco'. It is a matter of conjecture whether the dance came to the Adriatic directly from Spain through roving Spanish sailors, or from Sicily or Italy when Dalmatia formed part of the Venetian Republic whether it was originally a Moorish dance or a Spanish one, inspired by the struggle of Spanish Christians against the Moors is also debatable though the latter seems the most likely. We do know for certain that it is one of the oldest traditional European dances still performed, and that records exist of it being danced in Lerida in 1156 in a form portraying a Christian and National victory over the Moors and their expulsion from Aragon.
From the 12th century and particularly in the 16th and 17th centuries, the dance spread to many Mediterranean countries: to Italy, Corsica, Sicily, Malta, France and, through Spanish trade, to Flanders, Germany and even to England. It was subject to frequent local variations, in regard to plot, protagonists and eventually also to form. In Corsica it was danced by eighty swordsmen on each side, armed with two swords apiece, who did battle for the town of Mariana to the music of a solo violin; in Elba the engagement was between Christians and Turks, in other places between Arabs and Turks; sometimes the damsel in distress was a white maiden of royal blood, sometimes a Turkish or Moorish one of equal innocence and beauty. In Ferrara a dragon was introduced who tried to devour the damsel and there were many later versions which degenerated from the original war-dance (intrinsically a useful sword practice and 'keep-fit' class for the warriors of small island or coastal garrisons for whom good swordsmanship and alertness meant their survival) into a form of folk drama, and eventually into the dance interludes of pastoral plays and Italian opera. In Germany the Moreska, though called Moriskentanze, became a mere collection of local folk dances and in England the Morris (l.e. Moorish) dancers threw away their swords and substituted long wooden sticks which they fought with and over which they hopped. In most of the Mediterranean the Moreska survived until the end of the 18th century, and in Italy and Dalmatia till the close of the 19th.
Today, Korcula is the only island where it is still danced with real swords in its original War-Dance form and where it has enjoyed a proud and almost unbroken tradition for over four centuries, though the text, music and pattern of the dance have been slightly altered and shortened (the contest used to last for two hours!) over the years.
The introduction to the dance is a short drama in blank verse which sets the scene -- four characters recite the verses: the enemy or the Black King, his father, Otmanovic, (a kind of Balkan mediator), the Hero or the White King, and the Bula or Moslem maiden, who is a peace-maker as well as a heroine (and a possible convert to Christianity?).
The Moreska arrived in Korcula in the 16th century, at the same time as it did in Dubrovnik, most probably from Sicily or Southern Italy, via Venice. An indication of this is that two of the dance "figures" have Italian names: the "Rujer" and the "Rujer di fori via". "Ruggero" was the name of a Sicilian war-dance, a version of the Moreska, in which the Saracens are shown fighting against the Norman Prince Ruggiero d'Altavilla -- a powerful family who ruled over Sicily and Southern Italy in the 11th and 12th centuries, which suggests a possible link. There are, however, no written records of the Korculan dance until the beginning of the 18th century. Latterly and up to the first World War the Moreska was "fought" only every few years -- protagonists were often wounded and replaced by'seconds' during the dance -- between 1918 and 1939 it was performed every year under the aegis of the Gymnastic Society of Korcula. Nowadays it is an exclusive Society (and 'club') of its own and the Moreska is performed much more frequently for the benefit of the many tourists who visit the Island. Every family in Korcula is proud to have one of its members dance in the Moreska, especially one of the key roles, which demand considerable talent and stamina. When the Black or the White Kings "retire" they are allowed to keep their crowns and these become valued family possessions.
During the second World war costumes, swords, even musical scores and instruments had all been lost in the bombing and fighting and for the first time in its history only very young lads of between twelve and seventeen were available to dance the Moreska, and they had to be taught from scratch.
It was the undefeatable and indefatigable spirit of Ivo Lozica, the town barber, and Bozo Jerirevic, a school-teacher, with the help of a local policeman, Zdravko Stanic, and Josip Svoboda the conductor of the town orchestra, that somehow got the Moreska dancing again and in a very short time the poor, thin undernourished youths were growing into splendid young men and were taking the Moreska to youth conferences and festivals at home and abroad.
THE MORESKA DANCE
The revised score of the Moreska was composed by Krsto Odak who, working with Josip Svoboda, conductor of the town orchestra at the time, reconstructed an earlier score lost in the war. The Moreska from Korcula opens with a scene in which the Black King is seen dragging the captured Bula (Moslem maiden) along in chains trying to persuade her to respond to his love. The Bula refuses because she loves the White King and knows that he loves her.
The White King and his army and the Black King's army with banners and swords enter from either side. The two Kings confront each other and a dialogue of hurled insults and scorn ensues. The Kings are the first to cross swords while their armies stand facing each other and ready for battle. When the White King calls on his men to fight, the two armies clash swords and then break away from one another in order to make way for the Dance of the Black King, the graceful but menacing 'Sfida'. In this dance, which is performed in 6/8 rhythm, the Black King challenges the White King to a contest. The White King accepts the challenge, and then the Black King's father, Otmanovic and a soldier from the White King's army join the fight. They dance in a circle threatening one another with swords. The soldier withdraws leaving the two Kings and Otmanovic. At a given moment both armies, who are facing each other, leap forward and clash swords and then the Black King, still dancing, forms a circle with all the soldiers of both armies gradually joining in.
After this, seven Kolaps or "strokes" of the Moreska are danced in different and complicated rhythms and patterns and all are performed within this circle. The fight consists of alternating sword thrusts and parries. It is performed in pairs, i.e. one White against one Black fighter.
The seventh Kolap is performed in a speedy 4/4 rhythm and the swords clashes are fast and furious. The Black soldiers, facing outwards, defend themselves from within the circle which becomes smaller and tighter as they withdraw from the charges of the White army. Finally the Black soldiers fall down wounded, dying and defeated, laying their swords at their enemy's feet. The Black King admits defeat and surrenders, the White King, the Victor, frees the Bula from her chains and kisses her.
The following dialogue is translated from pat of the 19th century Croatian text of The Moreska published in Zadar in 1869.
Bula: Leave me alone! Your demands are in vain My charms belong to another man. Sweet Osman, my beloved, If you could see now How my heart is breaking And full of sorrow for you! Although this odious steel Binds my hands, My heart is always with you And yours with me. I shall bear you in my heart As long as I have life. Moro: Stop wailing, my lady I have had enough! It is painful for me to listen When you call my opponent your pride Here, in front of my face But I bear and endure it all For the love I feel for you My dear nymph, I give you my heart For your sweet charms. Bula: If you will But one favour grant me, All I ask Is that you stop loving me. Of far more pain for me Is your unwanted love Than the steel That weighs upon my hands. Moro: I will not leave you Nor will I stop loving you. I love honorably your everlasting beauty. Ask whatever you wish, Even my father's kingdom. Drums are heard. Enter the White Army. Otmanovic: There is no fear in Otmanovic! Osman: Do not trust your sword Without honour and without honesty. Treacherously, you wished to steal My betrothed, by torturing her. Where is your knightly honesty, Where your bravery

Released January 29, 2021.
Roughly 220 million tons of MSW are landfilled each year, across 1,500 MSW landfills (MSWLFs). One metric for the cost of disposal is the gate rate or tipping fee, i.e. the amount charged per ton for disposal at the landfill. EREF routinely surveys active MSWLFs across the U.S. to estimate the average MSWLF tipping fee nationally, regionally and on a state-by-state basis. The primary goal of the study is to track changes in MSWLF tip fee, and explore the relationship between tip fee and MSW management practices.
Results from this study will provide insight into the following types of questions:
- What is the average MSWLF tipping fee, and how does it vary across the U.S.?
- Are MSWLF tip fees increasing or decreasing each year?
- How does tip fee correlate to other MSW management practices (e.g. WTE, recycling)?

>>> pDoc = pApp.Document
>>> pMxDoc = CType(pDoc, esriMapUI.IMxDocument)
>>> pDisplay = pMxDoc.ActiveView.ScreenDisplay # something wrong here?
>>> pDisTrans = pDisplay.DisplayTransformation
>>> pageX, pageY = pDisTrans.FromMapPoint(ptInRealCoords) # coords are ~389700,~316671m
>>> pageX
_PHONE_ # which should be ~4.73 in cm
Any clues whats wrong?

IScreenDisplay's IDisplayTransformation.FromMapPoint transforms active view's coordinates into device coordinates (i.e. pixels). Moreover, you are accessing pMxDoc.ActiveView which will vary depending on whether you are in data view or page view. This means that the source unit space will be either map units or page units.
If you want to transform a coordinates in a certain map into page coordinates on the page layout you need:
 1. Transform the map's coordinates to the device space (i.e. cast the particular map as IActiveView and use its screen display's transformation, FromMapPoint).
 2. Transform the obtained device coordinates into page coordinates (i.e. cast the document's page layout as IActiveView and use its screen display transformation, ToMapPoint). Note that the name ToMapPoint here is slightly misleading as the "map point" here actually means page coordinates.

I was having trouble with this until I found this post _URL_.asp?c=93&f=992&t=84984 that further visualized the need to transform from map(data frame) coordinates to screen(monitor pixels) coordinates to "map"(page layout) coordinates. – TurboGus May 2 '13 at 15:35

Mixed-race is the fastest-growing ethnic group in the UK and is where a person's background is made up of two or more different ethnicities.
Although there's advantages in being exposed to multiple cultures, being mixed race also comes with challenges and complications, as people often feel pressured to identify with one race more than the other. It's very common for mixed race people to be perceived as either black or white, rather than both.
In this podcast, Eudene Griffith, Employability Trainer and Race Lead within the Diversity and Inclusion team, and Gemma Heywood, Employment Psychologist, share their experience of being mixed-race women.
They describe the confusion surrounding their identity as teenagers, being teased at school for their "fuzzy" hair and how they've learnt to reconcile, embrace, and adore their dual heritage as they've grown older.

Lightning Web Components Developer Guide. Chapter 3: Communication between Lightning Web Components
Here is our third article in the series on LWC. In the previous two, we delved into the principles of building and using components, as well as the basic tenets of markup and its features in LWC. In this article, we will explore communication between LWC components, so let's get started.
As a Lightning web component (LWC) developer, you may need to transfer data between components in cases where components are parent-child or unrelated. In this article, we will look at three ways to transfer data between LWC components:
 - Using the "@api" annotation.
 - Using dispatch event.
 - Using the Lightning message channel message service.
So let's go!
"@api" Annotation Properties
Let's take a look at the "@api" annotation. This annotation is used to define public properties and methods in a component that can be accessed by other components. This is especially useful when transferring data between parent and child components. We can define a public property in the child component using the "@api" annotation and set its value in the parent component. For example, we can define a public property in the child component as follows.
import { LightningElement, api } from 'lwc';
export default class ChildComponent extends LightningElement {
 @api message;
}
In the parent component, we can set the value of the 'message' property for the child component as follows:
<template>
 <c-child-component message="Hello World"></c-child-component>
</template>
In this example, we pass the 'Hello World' value from the parent component to the child component using the '@api' annotation.
Let's also consider the use of '@api' with functions. They allow invoking specific functionality of a component from outside, from other components or templates. This is a powerful tool for communication between components and exchanging data and actions.
You can declare a method in your LWC component and annotate it with '@api'. This allows the method to become public and accessible for invocation from other components.
import { LightningElement, api } from 'lwc';
export default class MyComponent extends LightningElement {
 @api
 myMethod(param) {
 console.log('Received parameter:', param);
 }
}
In another LWC component, you can reference the component containing a method annotated with "@api" and call that method.
<template>
 <c-my-component></c-my-component>
 <lightning-button label="Call Method" onclick={callMethod}></lightning-button>
</template>
import { LightningElement } from 'lwc';
export default class AnotherComponent extends LightningElement {
 callMethod() {
 const myComponent = this.template.querySelector('c-my-component');
 if (myComponent) {
 myComponent.myMethod('Hello from AnotherComponent');
 }
 }
}
In the example provided above, when the button is pressed on the parent component, the child component receives a specific text as a parameter and outputs it to the console.
The use of "@api" allows you to publicly export the functionality of your component and facilitate interaction with other components. Remember that adhering to security practices and robust design is crucial for effective communication between components.
Dispatch Event
Another way of communication between components is through dispatch events, which are used to transmit data between components that are not necessarily related. They can be used for data exchange between parent and child components, sibling components, or even components that do not belong to the same hierarchy.
Let's consider an example of a simple form where the user enters some data and clicks the 'Submit' button.
We can create a special event in the form component triggered when the user clicks the 'Submit' button. The event can contain the data entered by the user, which can then be passed to another component for further processing. Here is how we can create a special event in the form component:
import { LightningElement } from 'lwc';
export default class FormComponent extends LightningElement {
 handleSubmit() {
 const data = {
 name: this.template.querySelector('input[name="name"]').value,
 email: this.template.querySelector('input[name="email"]').value
 };

 const event = new CustomEvent('submitform', {
 detail: data
 });

 this.dispatchEvent(event);
 }
}
In this example, we create a special event named 'submitform' and pass it to an object containing the user-entered data. Then, we use the dispatchEvent method to trigger the event.
In another component, we can listen for the 'submitform' event and process the received data. Here is how we can listen for the event and handle the data:
import { LightningElement } from 'lwc';
export default class ResultComponent extends LightningElement {
 connectedCallback() {
 this.addEventListener('submitform', this.handleFormSubmit.bind(this));
 }
 handleFormSubmit(event) {
 const data = event.detail;
 console.log('Name: ${data.name}, Email: ${data.email}');
 }
}
In this example, we use the addEventListener method to listen for the 'submitform' event. When the event is triggered, the 'handleFormSubmit' method is called, and we retrieve the data passed in the event using the 'detail' property. This approach is useful when components do not belong to the same hierarchy.
Another way to handle events is by using the 'on' directive in the HTML file where the child component is invoked.
To capture this event in the parent component using the 'on' directive, you can do the following:
 - In the HTML file of the parent component, add the child component and include the 'on' directive:
<template>
 <div>
 <c-my-child-component onsubmitform={handleFormSubmit}></c-my-child-component>
 </div>
</template>
 - In the 'on' directive, specify the event name (in this case, onsubmitform) and the name of the function that will handle the event (in this case, handleFormSubmit). In the JavaScript file of the parent component, define the handleFormSubmit function:
handleFormSubmit(event) {
 const data = event.detail;
 console.log('Name: ${data.name}, Email: ${data.email}');
}
 - In the handleFormSubmit function, you can access the event properties and perform any necessary actions based on the data in the event.
Note that when using the 'on' directive, the event handling function must be defined in the JavaScript file of the parent component.
One of the advantages of using the 'on' directive is that it allows you to handle events more declaratively. By including the 'on' directive in the HTML file, you can see which events are being handled and which functions handle them, making code understanding and maintenance easier.
However, using the 'on' directive can also make the code less flexible. If you need to handle the same event in multiple components, you will need to define the event-handling function in the JavaScript file for each element. Conversely, if you use event listeners in the JavaScript file of the parent component, you can define the event handling function once and reuse it in multiple components.
In general, both approaches have their advantages and drawbacks, and the choice between them depends on the specific requirements of your project.
Let's also discuss the use of the "bubbles" and "composed" parameters in our dispatchEvent.
Bubbles
The 'bubbles' parameter is used when dispatching events in Lightning (LWC) to control whether the event 'bubbles' through the DOM hierarchy. Event bubbling is a mechanism where, after processing an event on a specific element, it then propagates up to parent elements for possible further handling.
In LWC, events typically bubble by default, similar to standard browser events. This means that if you dispatch an event from a child component, it will travel up through the hierarchy of parent components, allowing higher-level components to listen for the event and respond to it if they choose to do so. This natural event propagation can simplify the communication between components, enabling a parent component to respond to actions taken by its child components.
Lightning Web Components Developer Guide
Composed
The 'composed' parameter is another attribute used when dispatching events in LWC, and it determines whether the event can cross the boundary of the shadow DOM. Shadow DOM is a fundamental concept in web components that encapsulates a component's styles, structure, and functionality.
If the 'composed' parameter is set to true when dispatching an event, then this event can leave the boundaries of the shadow DOM and be processed by elements outside it. This can be useful if you want to communicate between components that are not directly related through the component hierarchy. However, setting the 'composed

use Mac::Apps::Anarchie; $ftp = new Mac::Apps::Anarchie; _TAG_ description for the rest
This is a MacPerl interface to the popular MacOS shareware FTP/archie client, Anarchie. For more info, see the Anarchie documentation.
Also required is the Mac::Apps::Launch module, which requires MacPerl 5.1.4r4.
NOTE: for some explanations of methods, drop Anarchie on Script Editor, and check the Anarchie docs.
Before using, you must autosplit the module. See version notes for 1.4 below.

NOTE: * denotes compatability with Fetch. Fetch does not use the variables SOCKS, FIRE, BINARY, or TYPE. Fetch implements some of these methods differently than Anarchie. To use Fetch instead of Anarchie for these methods, call the method:
There are two forms of each of the following methods: "method" and "methodURL". The methodURL version takes the user name, password, host and path in the URL instead of separately. URLs are usually in the form:
See Anarchie docs for more info on URLs.
Also, the host, username, password, proxy firewall and socks firewall can be preset and then omitted during the method call. This saves a lot of code writing if you are going to make multiple calls to the same host. If a method explicitly names any of those strings, it overrides presets. If username and password are not specified anywhere, FTP is done anonymously.
$ftp->host(HOST); $ftp->user(USER); $ftp->pass(PASS); $ftp->fire(FIRE); $ftp->socks(SOCKS);
If you don't want MacPerl to wait for Anarchie to finish what it is doing, then call this with the value 0. You can change it back to 1 if you do want it to wait. The initial setting is 1.
- fetch *
$ftp->fetch(FILENAME [, PATH, BINARY, TYPE, HOST, USER, PASS, FIRE, SOCKS]); $ftp->fetchURL(FILENAME [, URL, BINARY, TYPE, FIRE, SOCKS]);
Fetches file and saves to FILENAME on local drive. BINARY is boolean for whether file is binary or ascii. TYPE is the creator code to link file to. NOTE: for Fetch, FILENAME must be an existing directory name, NOT a filename. For Anarchie, FILENAME must be a file if the fetched item is a file or a directory if the fetched item is a directory. Anarchie will create FILENAME on the local drive if it does not exist.
- store *
$ftp->store(FILENAME [, PATH, BINARY, HOST, USER, PASS, FIRE, SOCKS]); $ftp->storeURL(FILENAME [, URL, BINARY, FIRE, SOCKS]);
Stores file FIELNAME from local drive to remote location specified.
- rename *
$ftp->rename(NEWNAME [, PATH, HOST, USER, PASS, FIRE, SOCKS]); $ftp->renameURL(NEWNAME [, URL, FIRE, SOCKS]);
Renames file NEWNAME to value in PATH or URL.
- remove *
$ftp->remove([PATH, HOST, USER, PASS, FIRE, SOCKS]); $ftp->removeURL([URL, FIRE, SOCKS]);
Removes file/directory specified in PATH or URL.
- mkdir *
$ftp->mkdir([PATH, HOST, USER, PASS, FIRE, SOCKS]); $ftp->mkdirURL([URL, FIRE, SOCKS]);
Make directory specified in PATH or URL.
- sendcommand *
$ftp->sendcommand([PATH, HOST, USER, PASS, FIRE, SOCKS]); $ftp->sendcommandURL([URL, FIRE, SOCKS]);

In the following jQuery, the.each() method takes two arguments: 'ul li a' and menu. What do these two arguments mean?
var menu = $('.menu');
$('ul li a', menu).each(function() {
 $(this).append('');

The second parameter to the jQuery function is the context. This tells jQuery to only search for elements that are in that context
So for your example:
This will only search for anchors within li's within a ul, that are also located inside of menu.
This can be a very useful optimization since it can significantly cut down the amount of space jQuery has to search.
To possibly make this a bit clearer (as jfriend00 points out), your particular example, $('ul li a', menu), is equivalent to $('.menu ul li a')
The context parameter is explained here in the docs

To clarify: $('ul li a', menu) is the same as $('.menu ul li a') in this particular case. – jfriend00 Dec 31 '11 at 5:53

Hello Brother Assalamu Alaikkum,
The explanation is as follows,
The first parameter is 'ul li a' It means that it searches for the anchor tag within the list item tag which in turn present inside the unordered list tag. This first argument is the sub context.
The second parameter menu which is the main context. That is jquery searches for the elements with the class name as "menu".
Finally jquery searches the sub context within the main context. So the jquery searches for the main context "menu" first and then it searches the sub context within the main context. The keyword "each" denotes all the sub elements to be searched within the main element.
hope this helps you.

Trickle)
Parallel in chunks is another type of snapshot approach where data objects are broken into chunks and snapshots are taken in parallel. Most of the tools support snapshot and the process are invoked in tandem. There are two ways to perform a snapshot in chunks: 1) table by table or 2) a large table split into small sets using primary keys or any unique row identifiers. In this approach, the snapshot duration and downtime window is greatly reduced. Good scripting skills required to prepare data migration tools for table or large table migration.
Snapshot - Parallel in Chunks (Trickle)
 - Data moved at one time with less downtime
 - Data moved in parallel - table by table or a large table in small sets
 - Application downtime required (less compared to Big Bang approach)
 - For large tables broken into small sets, primary key or unique row identifiers are mandatory
 - Script required to adjust the parallel approach
 - If a snapshot is interrupted, reinitiation is required.
5c. Change Data Capture (CDC - Data Sync)
There are different traditional Change Data Capture (CDC) approaches that have been available for decades. In the CDC model data migration, the software is designed to determine/track/capture the data that has changed on the source database in real-time and replay the same on the target database. Today CDC model software is in high demand because they distribute data between heterogeneous databases with low-latency, reliable, and scalable data. Most common CDC approaches for migrating Oracle to PostgreSQL databases are:
 - Trigger-based
 - Transaction Log-based
Trigger-based (CDC) — a remote trigger is created to capture DMLs (insert/update/delete) before or after and the sequence of transaction events is captured in changelog (shadow tables), then they are processed by the software to replay on the target database.
Transaction Log-based (CDC) — every database will have transaction logs (redos) to store all database transactions/events sequentially and be used in case of database crash recovery. Using native database transaction log plug-ins the transactions (DMLs) can be captured to change logs with some filters, transforms, and aggregations. Later, the sequence of captured DMLs will be replicated to the target database.
Both CDC approaches can be used to replicate data from Oracle to PostgreSQL. However, each has its own merits and limitations, depending on the requirements we can choose one of the available approaches. There are very good software options available to support both CDC approaches.
Change Data Capture
 - Data loaded continuously to target database (after initial snapshot)
 - User can access source database while data loads to target database
 - Data sync control (if interrupted, it can be resumed)
 - Partial replication (Set of tables can be replicated)
 - Need replication software
 - In trigger-based CDC, there could be a slight performance overhead
 - No Large Objects support
 - Partial to small application downtime (switchover time)
 - Only commercial/free to use tools available, no open source.
What Are the Free Tools Available for Data Migration?
There are open and free to use tools available for data migration in three different categories we have discussed in the blog. Below are the set of tools that we came across under those categories:

Use of engineered nanoparticles (NPs) in consumer products is resulting in NPs entering drinking water sources. Subsequent NP breakthrough into treated drinking water is a potential exposure route and human health threat.
Objectives:This study investigated the breakthrough of common NPs, silver, titanium dioxide (TiO2), and zinc oxide (ZnO), into finished drinking water following conventional and advanced treatment.
Methods:NPs were spiked into five experimental waters: groundwater, surface water, synthetic freshwater, synthetic freshwater with natural organic matter, and tertiary wastewater effluent. Bench scale coagulation/flocculation/sedimentation simulated conventional treatment, and microfiltration (MF) and ultrafiltration (UF) simulated advanced treatment.
Breakthrough of NPs into treated water was monitored by turbidity removal and inductively coupled plasma – mass spectrometry (ICP-MS).
Results:Conventional treatment resulted in 2-20%, 3-8%, and 48-99% of silver, TiO2, and ZnO NPs or their dissolved ions remaining in finished water, respectively. Breakthrough following MF was 1-45% for silver, 0-44% for TiO2, and 36-83% for ZnO. With UF, NP breakthrough was 0-2%, 0-4%, and 2-96% for silver, TiO2, and ZnO, respectively. Variability was dependent on NP stability with less breakthrough of aggregated NPs compared to stable NPs and dissolved NP ions.
Conclusions:Although a majority of aggregated or stable NPs were removed by simulated conventional and advanced treatment, NP metals were detectable in finished water. As environmental NP concentrations increase, we need to consider NPs as emerging drinking water contaminants, and determine appropriate drinking water treatment processes to fully remove NPs in an effort to reduce their potential harmful health outcomes.

Title: Understanding the Role of Solvation Forces on the Preferential Attachment of Nanoparticles in Liquid
We discuss optimization of colloidal nanoparticle synthesis techniques, which requires an understanding of underlying particle growth mechanisms. Nonclassical growth mechanisms are particularly important as they affect nanoparticle size and shape distributions, which in turn influence functional properties. For example, preferential attachment of nanoparticles is known to lead to the formation of mesocrystals, although the formation mechanism is currently not well-understood. Here we employ in situ liquid cell scanning transmission electron microscopy and steered molecular dynamics (SMD) simulations to demonstrate that the experimentally observed preference for end-to-end attachment of silver nanorods is a result of weaker solvation forces occurring at rod ends. In conclusion, SMD reveals that when the side of a nanorod approaches another rod, perturbation in the surface-bound water at the nanorod surface creates significant energy barriers to attachment. Additionally, rod morphology (i.e., facet shape) effects can explain the majority of the side attachment effects that are observed experimentally.

text: [Objective] To analyze the composition of endosymbiosis microbes of Martianus dermestoides at different stages, we took adult and larva as the research objects. [Methods] By the extraction of endosymbiosis microbes of Martianus dermestoides and high-throughput sequencing analysis, we obtained the composition and changes of microflora in different samples. [Results] At different insect stages, the endosymbiosis microbes abundance and diversity of Martianus dermestoides changed greatly with the development of the insect, the number of bacteria in the adult was relatively small, and the diversity was significantly lower than that in the larva. Different insect states had also significant differences in the composition of several specific microorganisms. Among the adult, Vagococcus and Lactobacillus were dominant bacterial genus; Lactobacillus in larvae was the dominant bacterial genus. The change of fungi was not obvious, and Saccharomyces spp. was dominant. [Conclusion] Our findings provide related information of biotic resources of Martianus dermestoides. Meanwhile, the result can also furnish the theoretical basis for the development and utilization of Martianus dermestoides endosymbiosis microorganism resources.

Estimating flood statistics from basin characteristics in Scotland
MetadataShow full item record
Estimation of the probability of occurrence of future flood events at a site is frequently required for the design of bridges, culverts, dams and other river engineering works. This study considers a method for estimating the flood frequency distribution from the physical characteristics of the drainage basin for use in Scotland when adequate records of river discharge are not available. The data base collated includes 3071 station years of annual maximum flood peaks for 168 high quality gauging stations and 12 physical characteristics for each drainage basin. A linear regression model is derived which explains 91% of the variation in the average magnitude of floods using five physical characteristics indexing drainage area, rainfall, stream density, soil type and lake storage. This model appears robust over the range of basin types and shows no improvement when shrinkage or ridge regression is employed. Five physically homogeneous subsets of basins are derived using a clustering algorithm (NORMIX) and the same five characteristics, with the addition of an index of channel slope. For each of subsets 1, 3, 4 and 5, the individual dimensionless flood frequency distributions for each station are not significantly different from a single GEV distribution derived for that subset. Consequently these subsets are considered to be hydrologically homogeneous in addition to their physical homogeneity. Dimensionless regional flood frequency distributions are produced for each subset which allow the estimated average flood magnitude to be scaled to estimate floods of less frequent occurrence. These regional 'growth curves' imply a larger return period for a given magnitude flood than those from the Natural Environment Research Council Flood Studies Report (NERC, 1975). When the floods are described by a lognormal model which allows for cross-correlation between stations the respective return periods are smaller.

FIX: Lenovo laptop is stuck at LOGO screen. (Solved)
If your Lenovo laptop stuck at the logo screen, then continue reading. This tutorial contains step by step instructions to fix the following problem on Lenovo laptops: After turning on, the laptop doesn't boot and hangs at the Lenovo logo splash screen. (The problem persists even when you try to boot from a USB bootable device).
FIX: Lenovo laptop is stuck at LOGO screen.
How to FIX: Laptop Stuck at LENOVO LOGO screen. *
* Important: Before troubleshooting a computer, disconnect all peripheral devices to make sure that the problem is not due to a connected device.
Step 1. Reset BIOS to default settings.
The first step to resolve the laptop freezing at Lenovo logo, is to reset the BIOS to default settings. To do that:
1. Turn OFF the Laptop by constantly pressing the power button for 5-7 seconds.
2. Now follow the instructions below according your model, to enter into BIOS:
 - If your system is ThinkPad, press the Power button and then immediately press the (Fn+) F2 or the (Fn+) F1 key rapidly and repeatedly.
 - If your system is ideapad laptop, locate and press the NOVO button, which is commonly located beside the Power button, and then select Enter BIOS Menu.
3. At Exit tab select Load Default Settings or "Load Optimized settings".
4. Save and exit from BIOS settings and see if you can boot to Windows.
5. If the laptop still freezes at Lenovo logo screen, continue to next step.
Step 2. Disable the Lenovo Service Engine.
In some Lenovo laptops (and desktops), the system hangs at "Lenovo Logo" during boot, when the "Lenovo Service Engine" is enabled. To disable the service:
1. Enter in BIOS menu.
2. At Security tab, highlight and disable the "Lenovo Service Engine".
3. Save and Exit from BIOS menu.
4. If the laptop still stuck at Lenovo logo splash screen, continue to next step.
Step 3: Perform a Power Reset.
The next method to resolve the "Lenovo Logo stuck" issue, is to perform a power reset. To do that:
1. Disconnect all connected peripherals.
2. Remove the AC Adapter.
3. Remove the Battery. *
* Note: If you cannot remove the battery, leave the laptop open until the battery is discharged.
4. Press and hold down the Power button for at least 50-60 seconds and then release the Power button.
5. Connect only the AC Adapter and turn on the laptop.
6. If Windows starts normally, shutdown your laptop and reconnect the battery and peripherals.
Step 4. Remove the CMOS battery.
1. Remove the Battery and the AC adapter.
2. Turn the laptop upside down and remove the back cover. *
* Note: The way of removing the back cover differs according the laptop model. So, perform a Google search about how to disassemble your own Lenovo laptop model.
3. Locate and remove the CMOS battery. *
* Note: The CMOS battery has shape like a circle and you can remove it out by gently prying it out with a small, flat-head screwdriver.
4. Press and hold down the Power button for at least 50-60 seconds and then release it.
5. Connect first the AC Adapter and then reinsert the CMOS battery.
5. Turn on the laptop. *
* Note: If the problem persists, remove and leave the CMOS battery unplugged for at least 30 minutes. Then, put the CMOS battery back, connect the AC Adapter and turn on the laptop.
Step 5. Remove the DVD unit. *
* Important: Turn off your computer and remove the Power Adapter, before adding or removing parts.
If you own a laptop with a DVD drive, then remove it and turn on your laptop again. (This sounds weird, but in some cases works.)
Step 6. Remove and Reseat the RAM & Hard Drive.
When a computer (desktop or laptop) freezes at LOGO (POST) screen, usually means a problem with the hard drive (HDD), or the memory (RAM). So, proceed as follows:
* Important: Turn off your computer and remove the Power Adapter, before adding or removing its parts.
1. Remove and reseat the RAM Module(s).
2. Turn on the laptop and see if the problem persists. If yes, then…
3. Turn off the laptop and remove (disconnect) the hard drive (HDD).
4. After removing the HDD, turn on the laptop again.
5. If the HDD is the cause of problem, then the Lenovo LOGO splash screen will disappear and you will receive a message saying "No bootable device found" or something like that. If this happen:*
a. Turn Off the laptop.
b. Clean the contacts on both hard drive and the HDD socket with a contact cleaner spray.
c. Reconnect the hard drive and continue reading below (6).
* Note: If this does not happen, this indicates a BIOS problem, or a motherboard problem, which can only be repaired by a specialized computer technician.
6. Turn on the laptop and see if the problem has solved. If not, proceed to backup your files and then perform a clean installation of Windows, by following the steps below:
a. Remove and connect the hard drive to another working computer (e.g. by using a USB to SATA Hard Drive Adapter).
b. If you can read the drive's contents, proceed and backup your files. *
* Note: If the hard drive is not recognized from the secondary computer, then the HDD is faulty and you have to replace it.
c. After backing up your files, proceed and diagnose the Hard Drive for problems, and according the results, replace the HDD (if it is faulty), or (if its OK) proceed and delete all partitions on the HDD.
7. After cleaning the partitions, put the HDD back on the laptop and proceed to clean install Windows.
That's all folks! Did it work for you?

Etch A Sketch Toys
Etch A Sketch toys are a fun game without the need for a digital connection, reams of paper, or pencils that need constant sharpening. Indulge your imagination with this drawing toy that easily and completely erases in seconds for the next creative image to come to life. Etch A Sketch games allow you to draw an infinite number of images to keep up with your creativity.What is an Etch A Sketch toy?
The 1960 release of the Etch A Sketch introduced it as a mechanical drawing toy with a thick, gray, glass screen inside a plastic red frame with two small white knobs. The knobs are twisted by hand to adjust the metal pointer, or stylus, under the screen in order to create a drawing, or sketch, with the powder contained inside. You then turn the Etch A Sketch upside down and shake it to erase the image and can immediately draw a new sketch on a blank slate.How does an Etch A Sketch toy work?
Inside the Etch A Sketch toy is aluminum powder fully coating the screen in order to draw a sketch. As the knobs are turned, the left one for horizontal movement and the right one for vertical movement, the stylus continues to push the powder away. The displaced powder leaves what appears to be a black or dark gray line on the Etch A Sketch display, but in reality it is just the empty space inside the Etch A Sketch. This effectively creates your sketch as you continue to adjust the knobs for vertical or horizontal movement. When you shake the Etch A Sketch, polystyrene beads help coat and redistribute the aluminum powder over the inside surface of the display.What are the benefits of drawing with Etch A Sketch?
Lineography is the act of drawing without lifting the medium from the surface. The Etch A Sketch is a lineographic toy; the stylus is able to move horizontally and vertically but not be removed from the underside of the display. The benefit of the Etch A Sketch is that you are able to release your hands from the toy as often as needed with the ability to pick back up exactly where you stopped. This action mimics the motion of drawing with a paintbrush or pencil. Another benefit of the Etch A Sketch is that your hands will remain clean throughout the drawing process.


text: SSLLP's theory of change envisions a Malawian society where small holder farmers are able to realize meaningful, tangible and sustainable livelihood benefits from agricultural enterprise and natural resources. SSLLP recognizes that this desired state can only be actualized when significant challenges have been addressed. This implies that SSLLP should seek to address internal and external factors that limit the ability of small holder farmers to realize such potential. SSLLP has modelled its theory of change on this important realization. SSLLP's approach is multi-faceted and targets all aspects of smallholder farming i.e. from the farm to the market and back addressing key decision-making points within that process so that farmers take their rightful place in the increasingly global context of smallholder agriculture. As part of its strategic focus, five themes were identified on which the program will concentrate in the next five years, to best use resources to achieve the vision of the organization.

Psi-calculi revisited: Connectivity and compositionality
Johannes Åman Pohjola
UNSW Sydney
Best paper award.
Psi-calculi is a parametric framework for process calculi similar to popular pi-calculus extensions such as the explicit fusion calculus, the applied pi-calculus and the spi calculus. Mechanised proofs of standard algebraic and congruence properties of bisimilarity apply to all calculi within the framework. A limitation of psi-calculi is that communication channels must be symmetric and transitive. In this paper, we give a new operational semantics to psi-calculi that allows us to lift these restrictions and simplify some of the proofs. The key technical innovation is to annotate transitions with a provenance - a description of the scope and channel they originate from. We give mechanised proofs that our extension is conservative, and that the standard algebraic and congruence properties of bisimilarity are maintained. We show correspondence with a reduction semantics and barbed bisimulation. We show how a pi-calculus with preorders that was previously beyond the scope of psi-calculi can be captured, and how to encode mixed choice under very strong quality criteria.
