A significant percentage of older adults live alone. According to Age UK and the U S. Institute on Aging, nearly half of adults 75 and older live alone in the U.K. and U.S. Older adults who live alone often have trouble remembering to take medication, connecting with family and friends, keeping appointments, and staying physically active.
Intuition Robotics recently introduced Elli-Q, an artificial intelligence-based robot that can act as a companion to help older people stay active and engaged. Because of the Elli-Q design aesthetic, the first public showing is at The Design Museum in London in January. The physical design consists of a tray with a two-piece articulated robot and a stand with a separate display screen that can be held in the hand or left in place. The Elli-Q robot uses lights, sounds, speech, images, and movement to communicate and to express what its creator calls "emotional expressions." The screen displays user-chosen content and can serve a two-way video communication function with family members or caregivers.
The design concept uses machine learning to react, engage, and communicate reminders and suggestions. The system monitors activity and stores information like prescriptions and calendars. Over time the idea is Elli-Q will learn the user's preferences, behavior, and personality. In addition to medication and appointment reminders, the robot will proactively recommend activities based on user history and on family input. Other potential functions include wellness and environmental monitoring, personalized music, audio books, social media access, photo sharing, and messaging.
Robotic companions such as Elli-Q have potential applications in wellness and health care for many populations. Intuition Robotics has not released pricing, technical data, or launch schedules for Elli-Q, but will run its first trial phase in the U.S. in homes of older adults in California in the Bay Area, starting in February 2017.

text: Cells from one-third of chronic lymphocytic leukemia (CLL) patients are resistant to alpha-interferon (alpha-IFN) as measured by induction of blast transformation. We have previously shown that all CLL clones express alpha/beta-IFN receptors, but that the resistant cells are defective in the induction of the enzyme 2′,5′-oligoadenylate synthetase (2′,5-A synthetase). Thus, the deficiency in IFN sensitivity is localized somewhere between the interaction of the IFN molecule with its receptor and induction of 2′,5′-A synthetase. We have now further characterized the resistance of CLL clones to IFN by investigating whether it is associated with a defect in the activation of IFN- stimulated gene factor 3 (ISGF3), which is involved in the activation of alpha-IFN-stimulated genes (ISGs). A defect induction of ISGF3 after alpha-IFN treatment was found in 4 of 12 CLL patients. There was a close correlation between defective induction of ISGF3 and a lack of enhancement of 2′,5′-A synthetase as well as induction of blast transformation. Pretreatment with gamma-IFN and mixing experiments with extracts from IFN-sensitive cells indicate that a lack of the gamma- component of ISGF3 was the reason for defect in activation in 2 of the patients. We conclude that a defect in activation of ISGF3 is a possible cause for resistance in CLL cells to IFN-induced blast transformation in vitro.

Master thesis presentation: Development of wireless interface in real-time data acquisition for artificial limb prostheses control system
Master thesis presentation: Development of wireless interface in real-time data acquisition for artificial limb prostheses control system by Presented by Thitipong Sansanayuth, MPBME.
Date: Thursday, June 4th
Place: Blå Rummet (room 6414), Hörsalsvägen 11, 6th floor
Supervisor: Max Ortiz-Catalan
Examiner: Bo Håkansson
AbstractArtificial limb control (ALC) system is a tool for helping patients to control their prosthetic limb.
To bring the most safety and the most convenience to the patients, a wireless
interface between the prosthesis and PC is required. In this thesis, the possibility to integrate
the wireless module to the ALC system was investigated. The available wireless
modules in the market was compared and selected. Bluetooth and WiFi technology was
studied. Selected WiFi and Bluetooth modules were tested by testing protocol to evaluate
the performance and the limitation of the modules. A hardware for implementing
both wireless modules was prepared and built. The wireless solution was integrated into
the ALC system and tested with a full recording session in BioPatRec platform. WiFi
allowed the raw EMG signal to be transmitted correctly. In contrast, Bluetooth is not
suggested for transmitting raw EMG signals for more than 4 channels or 256 kbps.
However, it has been proven that for data rate up to 128 kbps, Bluetooth works correctly
and may be alternatively solution for transmitting the signal feature instead.

Some of the highest mercury levels in the country are found in Georgia streams.
That's according to a federal study of mercury contamination that found the toxic substance in every fish tested at nearly 300 streams across the country.
The finding released Wednesday underscores how widespread mercury pollution has become.
The U.S. Geological Survey tested thousands of fish from 291 streams nationwide from 1998 to 2005.
Some of the highest levels in fish were detected in the remote blackwater streams along the coasts of the Carolinas, Georgia, Florida and Louisiana.
Mercury can damage the nervous system and cause learning disabilities in developing fetuses and young children.

Using keyboard for quizzes
Problem:
Is it possible to program an interactive quiz in which the user uses the keyboard instead of the mouse? How to do this? Where can I find some examples and tutorials?
The quiz on _URL_ forces the user to use the mouse.
I ask about this functionality because of AP's compatibility with Section 508 accessibility standards.
ActivePresenter Version: 7.5.11 Pro
OS: Win10
Regards,
Aga
Hi aga,
Yes, you can use the keyboard for most types of quizzes except Sequence and Drag-n-Drop.
 - You should set Tab Order for objects and use Tab / Shift+Tab to move among objects: _URL_
 - When a button has focus, the user can press space or enter to activate it.
 - In a True/False or Multiple Choice quiz, the user can press arrow keys to select a radio button.
 - In a Multiple Response quiz, the user can press tab / shift+tab to move among check boxes, and press space to check/uncheck a check box.
 - After answering a quiz, the user can press tab key to move focus to the submit button, then press enter to submit the quiz.
You can download that project, export to HTML5 with Enable Visual Focus Indicator option to see which object has focus and use the keyboard to answer the quizzes (except sequence, drag-n-drop quizzes): _URL_
Regards
Hi Toan Le,
thank you very much for your detailed answer.
The cited example of "Solar system" helped me understand the essence of this functionality.
Unfortunately when using the screen reader NVDA , the option of confirming the answer with the enter button disappears :frowning: Solution - we can use ALT+Enter instead.
Greetings,
Thank you for sharing this information.
I'm not sure why a screen reader can interfere with it.
For a button, you can also try using the Space key to activate it.
Regards
Thank you for reply.
Space key itself doesn't work. It's the same problem as with Enter key. You need to use a key combination: Alt+Space.
I have another questions.
 1. Why can't I use html headings h1,… ,hn, in AP? It's the most needed functionality for meeting accessibility standards for html documents.
 2. In PowerPoint I have "Alt" descrpitons in all images. When I import PP presentation to AP I lost all "Alt" descriptions. Is it possible to make AP not to lose those information? The same problem is with reading the order of the text fields on a given slide. I can set it on PP presentation, but AP import lost this information.
 Any solutions would be welcome.
Hi aga,
I don't think that it's important with interactive slide-based content as AP HTML5 output.
We'll consider support heading tags if there are more user requests.
From version 8 (which will be released this month), AP will import Alt descriptions as accessibility texts.
Do you mean the animation order in PowerPoint?
If so, animations started on click in PowerPoint will start from the beginning of the slide in ActivePresenter because there's no equivalent method in ActivePresenter.
Regards
Hi Toan Le,
thank you for response.
I'm looking forward to version 8.
Do you mean the animation order in PowerPoint?
No, that's not what I mean.It's not about animation. It is about the order of reading the static text fields on the slide. This is described here (topic: set reading order of slide contents)
Regards
Hi aga,
We keep the same order as in PowerPoint. You can check it in Timeline or Selection pane in AP.
(Select View > Selection to show Selection pane if it's hidden).
Regards
Hi Toan Le,
thanks a lot.
Everything looks simple.
But when I read an example (_URL_ exported to html5 using the NVDA screenreader, it skips some elements (e.g titles) on the slides.
I want to develop a presentation for blind people and I will continue to test the AP for this purpose :slight_smile:
Thank you for your help and kindness so far.
Hi aga,
It seems that from the second slide, only the focused object is read by the screen reader.
Please let us know if there's any other issues when you test AP for accessibility.
Regards
Hi Toan Le,
Yes, that's right. Only the focused object is read by the screen reader.
There is too much ARIA in the Solar-System-Quiz example. ARIA is often misunderstood as "general repair kit" for accessibility problems. Some ARIA features are not supported in any mobile screen readers for Android system (_URL_
We plan to test AP html5 pages with the team responsible for websites availability. The team manager is a blind person from the IT industry.

Posted 2 years ago Created 2 years ago 3 Minute(s) to read 0 comments
The following blog post presents a step-by-step guide on how to integrate Windows 10 features with your WPF desktop application written in C#, including the ability to display toast notifications ot the user.
Requirements
In order to integrate this functionality, you are going to require the following pieces of software.
Software
Packages
Using these NuGet packages is entirely optional, but are recommended for an easier development experience. This includes the creation, formatting, and presentation of toast notifications
Concepts
You will first need to familiarise yourself with some high-level concepts that are used including COM classes and objects, AppUserModel, and shell links.
Toast Activator
Your desktop application will require an implementation, or class definition that can be used for handling toast notification activations from the operating system (i.e. in this case Windows 10). This is a class that can receive signals or requests from Windows 10 whenever a user interacts or engages with a toast notification either from the hub or the prompt once it is displayed. It looks something like this.
// The GUID CLSID must be unique to your app. Create a new GUID if copying this code.
[ClassInterface(ClassInterfaceType.None)]
[ComSourceInterfaces(typeof(INotificationActivationCallback))]
[Guid("replaced-with-your-guid-C173E6ADF0C3"), ComVisible(true)]
public class MyNotificationActivator : NotificationActivator
{
 public override void OnActivated(string invokedArgs, NotificationUserInput userInput, string appUserModelId)
 {
 // TODO: Handle activation
 }
}
This code snippet defines the class that will be responsible for handling with requests from the toast notification once a user engages with it. The invoked args can be defined at a later stage once we construct the toast notification.
You will need to associate your application with a GUID that can be easily (and freely) generated from an online tool such as this website. Replace the example GUID string in the GuidAttribute with the one that you generated.
Project Setup
You will need to modify your existing C# project before being able to proceed in enabling toast notifications or other Windows 10 features in your application.
Open up the *.csproj file for your project in a text editor, and place the following XML elements below.
<PropertyGroup>
...
 <TargetFrameworkVersion>v4.7.1</TargetFrameworkVersion>
 <TargetPlatformVersion>10.0.17763.0</TargetPlatformVersion>
...
</PropertyGroup>
Change the version number of TargetPlatformVersion to the version number of the Windows 10 SDK that you have installed. Once completed, you will be required to reload the project when returning to Visual Studio. You should now have the ability to add references to WinRT references and libraries through the Reference Manager for the C# project.
Next, you will want to add references to a couple of WinRT references (*.winmd). Add references to Windows, and Windows.UI.
Reference Manager Frontend
For convenience, you will likely want to make use of this particular third-party package for invoking toast notifications without the setup.
Start Menu Shortcuts
As stated in the MSDN documentation for toast notifications, in order for it to work your application must have an associated shortcut in the Start Menu folder for Windows 10, that contains the CLSID of the COM object that is used for handling operations from Windows 10. You can make use of the following code snippet for resolving the absolute path to the Start Menu for the current user.
Shortcut Properties
You can make use of the following third-party NuGet packages for creating a shell link to your desktop application, and appending properties to it also. As mentioned above, you are going to need to add a property to your new *.lnk (Start Menu shortcut) that specifies the AppUserModelId.

ONE of Wales' most prominent buildings was bathed in blue light last night in support of an anti-bullying campaign.
The National Museum Wales in Cardiff, above, was floodlit to mark the Welsh Assembly Government's Respecting Others Week.
As part of the campaign, many children throughout Wales wore blue T-shirts to school, so the Assembly decided to light one of the nation's iconic buildings in the same colour.
The National Museum was chosen as it's one of the country's most recognisable buildings and is in a busy area.
"The Assembly Government wants to get the message across that when others stand by and do nothing, it actually encourages bullying tactics," said Minister for Education, Lifelong Learning and Skills, Jane Davidson.
"We want to get straight to the point to change behaviour, so that from now on, people will step forward, have a mutual respect for each other and help tackle bullying together."

The tents of the Central Asian nomads are an essential part of nomadic life and provide the sole form of formalized housing for the peoples. They are incredibly durable and perfectly fitted to use in the mountainous regions of Central Asia. Each tent itself is a work of art and takes almost 12 months to construct using yak wool that's hand spun into yarn.
Creating a Central Asian Nomadic Tent
The tents built by Central Asian nomadic tribes are generally mid-sized and are organized by handmade yak wool rope, and eight to twelve (depending on how big is the tent) treated wooden poles. The hand-spun fabric used to cover the canopy is relatively thin and does let in a specific amount of light during daylight hours. The canvas is created to include a sizable opening at the top of the tent that's used as a chimney or smoke hole release a smoke form a central dung fire stove situated in the tent. During warmer months of the season, these holes are also used to allow oxygen and warm sunshine into the living area within the canvas. Numerous Buddhist prayer flags are also attached to the outside the tent.
The within of most Central Asian nomadic tents are relatively basic with Spartan features and few belongings. However, there are always a few basics which are generally present in all nomadic tents of Central Asia and these include typically sleeping mats, warm woolen blankets, a dung fired stove, a wooden table of some sort, clothing and food storage areas and religious symbols including an image of the Dalai Lama and a Buddhist art thangka painting.
Directly outside the tent, traditional Central Asian nomads keep yaks and dogs tied up. The dogs are used as an application of security along with companionship, and the yaks are employed for their wool and their dung as a fuel source that's burnt in the ovens found in the _URL_
Central Asian Nomadic Tents in the Modern World
The use of traditional nomadic tents in Central Asia is declining rapidly due merely to the urbanization of elements of the traditionally nomadic peoples of the region, but besides, because more and more of the Central Asian tribesman are starting to live in mud-brick homes. Currently, the single aspects of Central Asia that still have an abundance of traditional nomadic tents that people use as a residence is found in the prefectures of Nagchu and Ngari in Tibet (known in China since the Tibet Autonomous Region) and in the Yushu and Ganzi prefectures of China proper.
The writer is a nomadic tent events coordinator who works in the South African corporate events market. He is closely associated with several events tents manufacturers in South Africa, including well-known brands such as Nomadik Tents and Touareg Tents.

Expert answers on finding your ancestors' census enumeration districts.
What's an enumeration district?
An enumeration district (ED for short) is an administrative division of a particular county or township for the purposes of census-taking. Each census taker would be assigned one or more EDs, each of which was designated with a number.
At one time, to find your ancestor's census return, you'd have to identify which roll of census microfilm contained the right ED. Now that US censuses have been indexed by name, people don't have to identify EDs the way they used to.
But you may find EDs handy for a few reasons:
- If you can't find a household in records for a database site such as Ancestry.com, you can browse by ED (in Ancestry.com, choose a census year, then scroll below the search box to pick a state, county or township; a ward; then an ED).
- Enumerators didn't always proceed through their EDs in orderly
fashion: Rather than go down one side of the street and up the other,
they might cross back and forth or double back to places where
no one was home. But you can compare a census return to a map of the
corresponding ED to plot the neighborhood and see who lived next to
- When the 1940 census comes out in 2012, a name index won't be available right away—but while you wait, you'll be able to find your ancestors' records using the ED.
To identify your ancestor's enumeration district, you'll need to know the state, city and street name, and possibly a street number. Then, try these tools:
- Stephen P. Morse's website has ED finding tools for the 1900 to 1940 censuses. Start by reading this overview to see which ED-finding tool you need (the 1940 tutorial quiz asks you a series of questions that will lead you to the ancestor's ED).
Morse's site also offers tools for ED number conversions between 1920 and 1930 censuses, and 1930 and 1940.

Research conducted to measure the performance of PSL when exposed to fire demonstrates that it is appropriate for use in all applications for which solid sawn lumber and timbers are suited.
As a result of evaluations done in Canada by the Canadian Construction Materials Center (CCMC) and in the US by the Council of American Building Officials (CABO) PSL has been accepted for use in Heavy Timber construction when of appropriate cross section. Like timbers and glulam members, PSL of large cross section has proven to be resistant to fire because the low thermal conductivity of wood retards heat penetration, and slow charring rates allow these large members to maintain a high percentage of their original section.
The Fire Safety Design in Buildings book provides further information on building code requirements relating to fire safety and details the minimum size requirements for Heavy Timber construction.
General guidelines for PSL:
- Determine the load capacity required.
- Select size of PSL member which will meet the required load capacity.
- Ask the local distributor for technical literature and contact the manufacturer if engineering assistance is required.
- Determine if PSL members will be directly exposed to weathering or high temperature and high humidity for significant periods during the life of the structure. If so, consult with the manufacturer for information about preservative treatment.
- Check local availability for sizes and lengths.
- PSL is a patented product manufactured in both Canada and the US. For additional product information or technical information, contact Weyerhaeuser.


Spatial chaos of an extensible conducting rod in a uniform magnetic field
D. Sinden & G.H.M. van der Heijden
The equilibrium equations for the isotropic Kirchhoff rod are known to form an integrable system. It is also known that the effects of extensibility and shearability of the rod do not break the integrable structure. Nor, as we have shown in a previous paper does the effect of a magnetic field on a conducting rod. Here we show, by means of Mel'nikov analysis, that, remarkably, the combined effects do destroy integrability; that is, the governing equations for an extensible current-carrying rod in a uniform magnetic field are nonintegrable. This result has implications for possible configurations of electrodynamic space tethers and may be relevant for electromechanical devices.

A vacuum cleaner is able to suck dirt off carpet because high pressure air from outside it flows toward low pressure air inside. In an electric vacuum, a fan causes air inside the vacuum to move quickly, which lowers the air pressure, causing suction. The higher-pressure air from outside the vacuum is sucked in to replace the low-pressure air, bringing dirt and dust with it to be caught in the filter bag. (Learn more about how vacuums work here.)
In this project you can make a hand-pump vacuum cleaner that alters the air pressure inside it and creates suction using a piston instead of a fan. Follow the procedure to make your vacuum, then read the explanation of how it works! An adult will need to help with the cutting.
1. Cut the bottom of the soda bottle off about 1/3 of the way up from the base. Now cut a slit down one side of the bottom third of the bottle - this will allow you to slide it inside the top part of the bottle so it can act as a piston.
2. Cut a 6'x3' strip of paper and fold it in half lengthwise for extra strength. Tape this strip to the bottom of the bottle to make a handle for your piston.
3. In the top part of the bottle, cut a 3/4-inch hole about 1-1/2 inches below the neck. This hole will lead to the filter bag.
4. Make a filter bag for your vacuum with a 6'x4' piece of tissue paper. Fold the paper rectangle in half and tape the sides to make a bag. Tape this over the hole you made near the neck of the bottle.
5. Tape one end of the thread to the ping-pong ball. Put the ball in the top part of the bottle. Feed the free end of the thread through the mouth of the bottle, and tape it to the outside of the bottle so the ping-pong ball hangs just slightly below the neck.
How does this contraption you just made work? Push the bottom part of the bottle into the top part, then pull it back sharply. This decreases the air pressure inside the bottle, because now there is a bigger space for the same amount of air. The lower-pressure air inside the bottle creates suction, pulling in higher-pressure air from outside in through the mouth. Now push the piston back in; this compresses the air and increases the pressure, so air flows back out of the bottle. The ping-pong ball works as a valve - when you push the piston in, it forces the ball into the neck of the bottle so that the air exits through the hole with the filter bag, rather than going out through the mouth.
Now put your vacuum to work! Try sucking up bread crumbs or tiny balls of paper. When you pull the piston out, they will be sucked into the bottle, and when you push the piston in, they will be forced into the filter bag.
Experiment to find out the best way to use your bottle vacuum. Does it work better to pump the piston rapidly? Should you pull out on the piston faster than you push in on it? Can you think of ideas to improve the design and efficiency of your vacuum? Give them a try!

Coasters vessel freight to Burullus • Small fishing port turned into a transportation hub for Mega gas- and steam combined cycle power station
The final push for a gigantic order: Until September, DB Schenker will be transporting a total of 100,000 tons with 400,000 cbm of freight to Egypt for Siemens AG, which is building one of the largest gas-fired power stations in the world. Burullus is the site of one of three Siemens power stations. Powered by natural gas, each plant has a capacity of 4.8 gigawatts, which will be generated by eight Siemens gas turbines and four steam turbines. This technology has been selected for its high efficiency. A 600-ton crane unloads the turbines in Burullus. The heavy parts are delivered at a specially reinforced pier. The heavy parts, such as generators and turbines, are lifted with steel ropes.
The individual components include turbines, generators, transformers, and boilers, with single weights up to almost 500 tons. Each of the three power stations requires 248 of these massive components in total. Download: Infographic
The heavy components from Europe and the USA are shipped straight to the Burullus fishing port. Parts from Asia arrive first at the port of Alexandria by ocean-going ship. There, they are reloaded onto smaller coasters which can access the port at Burullus, some 80 kilometers away, thanks to their smaller draft.
DB Schenker undertook the necessary preparation work to ensure the massive components could be unloaded at Burullus harbor: Its depth had to be increased to 5.50 meters and a pier needed reinforcement, while access routes and facilities for temporary storage had to be constructed. A 600 ton crane was installed to discharge the individual components to low-bed trailers. The port at Burullus is just 16 kilometers from the construction site.
All three power stations are going on stream successively already since the end of 2016.

This webinar originally occurred on January 6, 2022
Duration: 1 hour
Since the development of early firearms in the mid-1200s, the best material for making critical parts for weapons has been iron-based metal. While iron and steel (an alloy metal that contains iron) are popular materials due to their strength and resilience, they are susceptible to chemical reactions when interacting with the environment. The most common chemical reaction of concern is corrosion or rust, which causes metal to deteriorate or dissolve. Corrosion and chemical reactions most often occur in wet and humid conditions. If firearms are not properly cared for or are left in these conditions, it could have adverse effects on the firearms' operability and could affect the firearms' individual characteristics.
While past research has been performed on the possibility of identifying characteristics on rusted firearms after they have been restored, there is little research on how long a firearm can be left to rust before an identification is no longer possible. Potential identification comparisons were performed on cartridge cases and projectiles after they were test fired through firearms that were left to rust for certain periods of time. This project evaluates the effects of rust on the common working surfaces of Glock and Smith & Wesson Sigma firearms that firearm examiners use to make an identification. The unpredictable data suggests that Glocks cannot be identified past three months of rusting while Sigmas can be identified at six months and possibly even longer.
Detailed Learning Objectives
- Attendees will learn the adverse effects of corrosion and rust on a firearm's operability and individual characteristics.
- Attendees will learn the length of time a firearm, both with conventional and polygonal rifling, can rust before individual characteristics are altered or changed enough to where an identification can no longer be made.
- Attendees will learn whether the amount of time a firearm has been rusting can be estimated based on the condition in which it was found.

Water Vapor Layer
Have you come across water vapor data for a layer? I've only ever seen that as an image, like _URL_
Weather satellites provide images of Earth mainly in 3 channels
(visible, infrared and water vapour).
Water vapour images show the air streams and water vapour content
in the upper and middle levels of the troposphere.
If you want to see the humidity at different layers in the atmosphere,
you can use "humidity" and height slider.
e.g. here you see humidity over USA at 10,000ft.

Improving the objective function in minimum error rate training
He, Yifan and Way, Andy (2009) Improving the objective function in minimum error rate training. In: MT Summit XII - The twelfth Machine Translation Summit, 26-30 August 2009, Ottawa, Canada.
Full text available as:
In Minimum Error Rate Training (MERT), the parameters of an SMT system are tuned on a certain evaluation metric to improve translation quality. In this paper, we present empirical results in which parameters tuned on one metric (e.g. BLEU) may not lead to optimal scores on the same metric. The score can be improved significantly by tuning on an entirely different metric (e.g. METEOR, by 0.82
BLEU points or 3.38% relative improvement on WMT08 English–French dataset). We analyse the impact of choice of objective function in MERT and further propose three
combination strategies of different metrics to reduce the bias of a single metric, and obtain parameters that receive better scores (0.99 BLEU points or 4.08% relative improvement) on evaluation metrics than those tuned on the
standalone metric itself.

How to execute multiple commands through a text file with a Domino server
Technote (FAQ)
Is it possible to execute scripts or a list of commands through a text file on a Domino server?
You can create a text file that lists the commands you would like to execute on the Domino server. The commands which you can include can be anything that can be typed at the server's console. To load the script you must use the < command (less-than symbol), followed by a blank space, and then the name of the text file you created. For example, if you need to execute these commands:
you can create a file called F:\MYFILE.TXT, and within this text file, enter the commands that are to be executed. After you save the.TXT file, enter the following at the Domino server console:
If there is more than one command in the.TXT file, they will be executed in the order in which they appear in the.TXT file.
All commands in the.TXT file could be encapsulated with
start consolelog
in the first line and in the last line
stop consolelog
to write the output into the console.log file.
Note: "stop consolelog" will close any logging launched manually or by CONSOLE_LOG_ENABLED=1 in notes.ini.
These type of batch files are not supported by Lotus.

Here's an unlikely effect of recession: It may actually be helping some Americans improve their health.
The majority of middle-class Americans say they are healthier because of frugal behaviors during the last year, including cooking at home or spending less on junk food, according to the results of a survey that the financial planning firm First Command Financial Services plans to release this week.
Nearly half of those responding to the survey said their frugal behaviors were making them healthier, while another 45 percent said at least a portion of their frugal behaviors were making them healthier.
"These survey results reveal an important connection between personal finance and health," Scott Spiker, chief executive of First Command Financial Services, said in a statement.
So what are some examples of the frugal behaviors respondents are engaging in?
According to the results, 45 percent of respondents said they have cut back in the last year by cooking at home more often; 30 percent said they were spending less on junk food; 13 percent said they have reduced driving costs by walking or riding a bicycle to work; 10 percent said they have reduced spending on alcohol; and 7 percent said they were growing their own food.
In contrast, just 2 percent said they had canceled or postponed the purchase of home exercise equipment, 3 percent said they had quit smoking and 6 percent said they had reduced spending on medicine, prescriptions, vitamins and dietary supplements.
The survey data was collected in April as part of First Command's monthly online survey of about 1,000 consumers in the United States age 25 to 70 with annual household incomes of at least $50,000. The monthly results are compiled by the market research firm Sentient Decision Science, and April was the first month the survey, called the Financial Behaviors Index, asked about the health effects of frugal behaviors.
Still, some respondents — 6 percent — said their frugal behaviors were making them less healthy.
Do you agree with the survey results? Why or why not? What effect are your frugal behaviors having on your health?

I need to combine all this and the following into one inequality. Is there a common factor that we can multiply to one or the other or something? Can we exploit the fact that ranges are known? How do we proceed in such a case? Any help is appreciated.

Lesson Transcript
Instructor: Kerry Gray
One of the text structures that authors often choose when giving instructions is sequential order. In this lesson, we will examine this text structure and discuss strategies for putting sentences in the proper sequence.
Sequencing as a Text Structure
Think about the steps involved in baking a cake. What would happen if you changed the order? There's a reason the recipe says to preheat the oven before mixing the batter. Sequence matters, and sequencing is putting the steps in a process in order from beginning to end. It's an important skill, not only for reading comprehension, but is also used in other content areas, such as math, science, and social studies. Let's examine some sequence structures that will help you organize instructions in a passage.
Chronology vs Sequence
A common error with putting things in sequential order is assuming that it's the same as putting things in chronological order. Chronology has to do with the time that something happens. For example, on the Titanic's maiden voyage, this is the chronology:
Chronology of the Sinking of the Titanic
 - April 14, 11:40 PM, the Titanic strikes an iceberg.
 - April 15, 12:05 AM, Captain Smith orders the crew to prepare the lifeboats.
 - April 15, 12:45 AM, the first lifeboat is launched.
 - April 15, 2:20 AM, the Titanic sinks.
 - April 15, 4:10 AM, the Carpathia picks up the first lifeboat.
The chronology describes the order of events at a particular time and setting. Baking a cake is a sequence of events because it doesn't matter when or where you start; the order of the process will remain the same. For example, here is the sequence of making a cake:
Sequence of Baking a Cake
 1. Preheat the oven.
 2. Lightly grease the pan.
 3. Mix the ingredients in a bowl.
 4. Pour the batter in the pan.
 5. Place the pan in the oven and bake for 35 minutes.
Whether you make the cake now or wait until your birthday, the sequence is consistent. Sequencing is the text structure that is generally used when the author is giving instructions. Signal words that you will often see when things are put in sequential order include: first, next, before, lastly, finally, and then.
Sample Passage
To illustrate the importance of sequence, let's read the following passage.
How to Make a Peanut Butter and Jelly Sandwich
Then, you'll use a butter knife to spread approximately 2 tablespoons of peanut butter evenly across the top of one of the slices of bread. The next step will be to spread approximately 1 tablespoon of jelly evenly across the top of the other slice of bread. The first step to making a peanut butter and jelly sandwich is to go to the store to purchase bread, peanut butter, and jelly. Next, you'll remove two pieces of bread and place them side-by-side on a plate. Finally, you'll place the slice of bread that's covered with peanut butter upside-down on top of the slice of bread that's covered with jelly so that the peanut butter and jelly are facing each other.
While all of the steps are in place, this passage doesn't make a lot of sense. To put it back in the proper order, let's look for some transition words. The first sentence will be the one that begins with 'The first step…'
It's also pretty easy to find the final sentence in the sequence because it begins with the transition word 'Finally.'

The global burden of mental disorders and the need to improve the quality of mental health services
Μagdalini Triantafyllidou
Introduction: Mental disorders are one of the main causes of the overall disease burden worldwide as it is estimated that one of four people will experience a mental health problem in their lifetime. Purpose: The purpose of the current article is to present the extent of the impact of mental disorders on personal health as well as the factors that afflict health. Furthermore it aims to describe the need of integration of the World Health Organization's (WHO's) recommendations into health policies in order to improve the quality of mental health services. Material and Methods: The methodology that was followed in this paper was the review of Greek and international bibliography on the PubMed, Scopus and Medline databases on the subject of quality of health services and the presentation of the latest data in the global burden of mental disorders as well as in the socio-economic factors that affect mental health. Moreover, WHO recommendations for the improvement of mental health services quality and the changes in mental health legislation that Greek government introduced in 2017, are presented. Results: The negative mental health impacts urge the adoption of WHO's recommendations by introducing measures that focus on improving quality in mental health services. In Greece, the most recent attempt to reform mental health services is intended to help improve the quality of mental health services. However, it does not appear to be in line with WHO's recommendations as necessary quality improvement components, such as the efficiency and evaluation criteria, are absent. Conclusions: Overcoming the administrative deficiencies of the healthcare system in Greece is of great importance for the national adaptation policy processes in improving the quality of mental health services.
Keywords: Quality of healthcare and mental healthcare services, WHO's recommendations, administrative reform of mental health services, global burden of mental disorders

Frederic Eugene IvesArticle Free Pass
Frederic Eugene Ives, (born Feb. 17, 1856, Litchfield, Conn., U.S.—died May 27, 1937, Philadelphia), American photographer and inventor.
As a boy, Ives was apprenticed to a printer at the Litchfield Enquirer, where he became interested in photography. By the time he was 18 years old, he was in charge of the Cornell University photographic laboratory. While there, he developed an early halftone process using a gelatin relief. He continued to improve this process, and in 1881 he worked on the first commercial production of halftone printing plates using his method; in 1885 he introduced an improved halftone screen.
Among Ives's 70 patents were those for halftone photogravure (anticipating rotogravure); the modern short-tube, single-objective binocular microscope; and the photochromoscope (also called kromskop) camera and the chromogram (also spelled kromogram). The latter, a viewing instrument that accurately combined and projected the three-separation colour negative produced by the former, was of particular importance in the development of full-colour projection. Some of his early prints are preserved in the Smithsonian Institution, Washington, D.C.

Download (185Kb) | Preview
Language exists in order that people can communicate to each other. In its development, language can change. The changes of language can create language variations. One aspect that makes language variations is geographical aspect. Different area can create the variation of language. It happens in English. The researcher takes American and British English. This research is to get the differences of language used between American and British English which are represented in novel "Harry Potter and the Half Blood Prince." This research was intended to find verb differences, tenses differences, and language expression differences in this novel. The design of this research was descriptive research. Moreover, this research used qualitative research. Besides, this research employed documentary analysis. There are fourty nine verb differences, six tense differences, and one hundreds and one language expression differences found in this novel. In verb differences, there are four verb differences in transitive, six verb differences in intransitive, twenty six verb differences in phrasal verb, three verb differences between intransitive and phrasal verb, five verb differences between transitive and phrasal verb, one verb difference in modal auxiliary, three verb differences in auxiliary be, one verb difference between modal and auxiliary and auxiliary be. In tenses differences, one sentence in American version uses present tense while British version uses simple past tense, seven sentences in American version uses simple past tense while British version uses past perfect tense, one sentence in American version uses past perfect tense while British version uses continuous tense, two sentences in American version uses present tense while British version uses continuous tense, one sentence in American version uses continuous tense while British version uses past tense, one sentence in American version uses present modal while British version uses past modal. In language expression differences, There are language expression differences in comparative, in singular and plural, in conjunction, in noun, in noun phrase, in clauses, in pronoun, in preposition, in adjective, in possessive form, in adverb, in sentence, and the other language expression differences in which there are the existence of some words in some sentences while the others are not in both American and British version. All the differences are similar in the meaning.

DHCW pleased to enable the Welsh vaccine passport
We're helping to give Welsh people access to vaccination 'passport' certificates.
Our tech and data experts have worked collaboratively with NHS Digital to develop a solution to ensure Welsh vaccination data is available through NHS England's digital COVID Pass service.
This means people in Wales can now access their vaccination status on the internet if they need to travel urgently and meet the vaccine requirements relevant to the country they are travelling to. The NHS COVID Pass can be accessed here.
On day one (25 June) DHCW uploaded over 3.7 million records to the COVID pass service, with ongoing data flows to keep vaccine records up to date.
We also developed the software and database needed to manage requests from people requesting a COVID pass letter.
NHS COVID Pass letters have been available in Wales since May for those who need to urgently travel internationally and provide proof of their vaccination status, with certificates being sent in the post. To date over 18,000 have been requested. The letters will continue to be issued only for people who are unable to access the digital Pass through the Welsh Vaccination Certification Service (WVCS), delivered by Swansea Council's contact tracing team. People can request a bilingual NHS COVID Pass letter by calling 0300 _PHONE_.
The NHS App that is used in England is not available for people to use in Wales currently.

The Investigate dashboard enables you to view pivot tables of metrics and attributes for all API traffic and compare relational activity between metrics to investigate and diagnose issues faster. You can access data for the past 30 days in the dashboard.
Select Analyze > API Monitoring > Investigate in the Edge UI to open the Investivate dashboard. The dashboard has two main areas:
- Status Code lets you investigate status code metrics for API proxies and target services.
- Latency lets you investigate latency issues for API proxies and target services.
You can also investigate issues caused by a specific alert in the Investigate dashboard. When an alert occurs, click the name of the alert in the Alert History page to opent the alert in the Invesitgate dashboard.
Use the Investigate dashboard to diagnose an issue
For example, you receive an alert that indicates that the 5xx error rate exceeds the specified threshold. To investigate this issue, you might perform the following tasks on the Investigate dashboard:
- View the fault code versus time matrix to view the fault code activity over the last hour.
- Switch to the fault code versus HTTP status matrix to identify specific HTTP status codes associated with the fault codes whose counts have increased over the last hour, as identified in the previous step.
- Switch to the fault code versus Proxy matrix to identify the API proxies that are triggering the fault codes identified in the previous step.
- Click a box in the matrix that is associated with an API proxy with a high volume of fault codes to view more details and access logs.
- Set up an alert and create a custom report to further assist with diagnosing the issue.
Further troubleshoot the API proxy using trace and other tools to identify a resolution to the issue.
Use the Status Code dashboard
The Status Code dashboard lets you investigate status code metrics for the API proxies and target services in your organization. You can view status code metrics for a one-hour or four-hour window at any time in the past 30 days.
Explore the Status Code dashboard
To display the Status Code dashboard, select Analyze > API Monitoring > Investigate in the Edge UI. The Status Code dashboard displays by default:
As highlighted in the figure, the Investigate dashboard enables you to:
- Configure each matrix by setting its x-axis and y-axis to compare the relational activity between metrics and gain more insights.
- Quickly identify the metrics that are experiencing the highest relative volumes based on the color shading of a block. The darker the block, the higher the relative volume.
- Click a block in the matrix to view metric details.
- Filter the data based on the following:
- Status codes (including all traffic, all errors, 2xx, 4xx, or 5xx)
- Date and time in the past 30 days
- 1-hour or 4-hour window
Use the dashboard to quickly perform the following tasks:
- Access logs in the metric details panel.
- View the current context in the Recent or Timeline or dashboard by clicking > View in Recent or View in Timeline, respectively.
- Create a custom report and add additional dimensions by clicking.
- Create an alert and add additional alert conditions, set up notifications, and generate a custom report based on the alert.
Configure the Status Code matrix
When you select the Status Code dashboard, the following matrices appear by default:
- Fault code versus time
- Fault code versus HTTP status
- Fault source versus API proxy
Configure each matrix to compare any two of the following metrics by selecting a value for the x- and y-axis drop-down lists:
- Fault code
- Fault policy
- Fault source
- HTTP status
- Target (Target service or the ServiceCallout policy. If the target is a ServiceCallout policy, then the displayed
value is prefixed by
sc://. For example,
View Status Code metric details
View details for a particular metric by clicking its block in the matrix.
Details pertaining to the suspected cause are displayed in the right pane, including:
- Fault Source (proxy, target, or Apigee infrastructure)
Details may also include:
- Fault Policy - Information about the policy that triggered the runtime error, including policy type (internal name) and user-defined policy name. You define the name when attaching the policy to the API proxy flow.
- Proxy name
- HTTP Status code
- Fault Code
If the cardinality is greater than one for a specific metric, the details panel may include error distribution details, such as Distribution by Developer App, Distribution by Fault Policy, Distribution by Fault Code, Distribution by HTTP Status, and so on. For example:
If the fault source is target, the details panel will include Error Rate by Target. For example:
Use the Latency dashboard
The Latency dashboard displays latency information for the API proxies and target services in your organization. You can investigate latency metrics for a one-hour winow at any time in the past 30 days.
Explore the Latency dashboard
To display the Latency dashboard, select Analyze > API Monitoring > Investigate in the Edge UI. The Status Code dashboard displays by default. Select Latency in the filter area to display the Latency dashboard.:
When you select the Latency dashboard, the following matrices appear by default:
- Proxy vs Time (max latency in milliseconds)
- Proxy vs Total latency (max latency in milliseconds)
- Proxy vs All targets latency (max latency in milliseconds)
Use the Proxy drop-down box to select Target to view target latencies.
By default, the Latency dashboard shows information for the 10 proxies with the highest total P99 latency for the previous hour. Alternatively, use the Top 10 drop-down box to select a specific proxy or collection.
The Latency dashboard has all of the features of the Status Code dashboard, with the following differences:
- You only configure the total response latency percentile (p50, p90, p95, p99).
- You can only select a one-hour window for latency metrics.
- You cannot select Any for Region in the filters. You must select a specific region to view.
View Latency metric details
View details for a particular metric by clicking its block in the matrix.
Details pertaining to the latency for a proxy (blue line) and target (purple line) are displayed in the right pane, including:
- Total latency (proxy latency plus target latency)
- Latency per target (target response time)
- Distribution by HTTP Status
Hover over the graph to view detailed information:

Because Salisbury is situated between the Chesapeake Bay and the Atlantic Ocean, the climate here is rather mild, and the weather often humid. In the summer the high temperatures range from 85 F (29 C) to 95F (35C) and in the winter the lows range from 20F (-12C) to 30F (-6.5C), with 40F (4.5 C) being the average winter temperature. Although Salisbury rarely experiences extreme weather conditions (i.e. hurricanes, tornadoes, blizzards), heavy thunderstorms occur from April through September. This mild climate provides for small amount of snow during our short winter, beautiful springs, tropical summers and warm autumns.

Waite Arboretum Labyrinth
The purpose of the Waite Arboretum Labyrinth is to be an aesthetically pleasing element linking the Urrbrae House Gardens and the Waite Arboretum. The Labyrith aims to provide a beautiful, tranquil setting for contemplative walking – but feel free to run, skip or dance it!
The Labyrinth is located on the original site of Peter Waite's tennis courts, overlooked from the Rose Garden with a wonderful view towards the Arboretum.
The lines of the labyrinth are formed with 921 timber rounds mostly recycled from Arboretum trees and the paths are sawdust. The whole installation is intended to be ephemeral or renewable and sit softly on the landscape.
Dr Jennifer Gardner the Director of the Waite Arboretum and Conservation Reserve personally designed and constructed this labyrinth, completing it in mid January 2010. Jennifer states "It was an enormously pleasurable, stimulating and satisfying way to spend my Christmas holidays and I am delighted by how many children it has attracted to the gardens."
Arboretum groundsperson Mark Ziersch skilfully cut most of the rounds while, Giles Goldney cut the Norfolk Island Pine. All rounds used in the Labyrinth were collected from dead trees or fallen branches. It is a long standing policy that the Arboretum recycle timbers for carving, turning and other artworks giving the tree new life as objects of beauty.
Labyrinths are thought to date back 20,000 years and occur across continents and cultures in many different designs and materials. The pattern in the Waite Labyrinth was based on an ancient Finnish 9–circuit stone labyrinth.
Labyrinths have also long been recognised for their health benefits, promoting a calm mind and a place for mediation.
In colloquial English, labyrinth is generally synonymous with maze, but many contemporary scholars observe a distinction between the two. A maze refers to a complex branching puzzle with choices of path and direction, while a single-path (unicursal) labyrinth has only a single, non-branching path, which leads to the center. A labyrinth in this sense has an unambiguous route to the center and back and is not designed to be difficult to navigate.
Both the Latin labyrinthus and Ancient Greek labýrinthos mean 'maze'.
In contemporary usage however labyrinths and mazes are distinguished as follows:
|One simple continuous path (unicursal) to the centre and out again, no dead ends.||A puzzle, confounding pathways with branching paths and dead ends.|
|The centre or 'goal' visible at all times.||The centre or 'goal' hidden until you reach it.|
|Usually 2-dimensional or with very low divisional lines.||
3-dimensional, dividing lines tall enough to obscure the goal.
|Design may be marked with a variety of materials e.g. different coloured pavers, ceramic tiles, stones, low mounds, herbaceous borders, painted lines, depressions in clay tablets (hand labyrinths) – even timber rounds!||Divisional lines made of hedges, vertical fabric partitions, masonry etc.|

Drought dries New Mexico's largest rivers
UPDATED 08-22-12, 8:00 PM:
Additional rains have reconnected flows within the stretch of the Pecos River that includes habitat for the Pecos bluntnose shiner. Biologists do not plan to conduct salvage work this week. About 30 miles of the river still remain dry.
This has been a dry year in New Mexico. Statewide, we've received only half the precipitation of average, and most of eastern New Mexico is experiencing what the National Weather Service calls "extreme drought."
That means this has been a tough summer for New Mexico's two largest rivers.
Since mid-June, two stretches of the Rio Grande south of Albuquerque have gone dry. Right now, a total of about 50 miles are dry.
Meanwhile, about 30 miles of the Pecos River have dried between the city of Roswell and Bitter Lakes National Wildlife Refuge. According to online stream gages, the drying first began in July.
To try and keep water between the banks of the Pecos, the U.S. Bureau of Reclamation has been buying and leasing water rights from willing sellers.
But the drought this year has been too much for the agency to keep up with, according to the Bureau of Reclamation's Gary Dean.
Conditions haven't been this dry on the Pecos since 1989, he says, when the agency conducted a dam safety test of Brantley Dam and had to temporarily hold back the river's flows.
Now, biologists with the U.S. Fish and Wildlife Service are preparing to rescue rare fish—the pecos bluntnose shiner-- from the drying riverbed.
According to Stephen Davenport, with the U.S. Fish and Wildlife Service's New Mexico Fish and Wildlife Conservation Office, a rainstorm on Tuesday night caused a temporary spike in flows throughout the fish's habitat, but biologist will likely head out to the Pecos River for salvage work later this week.


Tremella mesenterica
Tremella mesenterica
''Tremella mesenterica'' is a common jelly fungus in the Tremellaceae family of the Agaricomycotina. It is most frequently found on dead but attached and on recently fallen branches, especially of angiosperms, as a parasite of wood decay fungi in the genus ''Peniophora''. The gelatinous, orange-yellow fruit body of the fungus, which can grow up to 7.5 cm diameter, has a convoluted or lobed surface that is greasy or slimy when damp. It grows in crevices in bark, appearing during rainy weather. Within a few days after rain it dries into a thin film or shriveled mass capable of reviving after subsequent rain. This fungus occurs widely in deciduous and mixed forests and is widely distributed in temperate and tropical regions that include Africa, Asia, Australia, Europe, North and South America. Although considered bland and flavorless, the fungus is edible. ''Tremella mesenterica'' produces carbohydrates that are attracting research interest because of their various biological activities.

This is the third and final post in the sequel concerning 'a new vision for your health and wellbeing in 2016'. Today's focus is on the essential components of your health and wellbeing plan. We'll address what to include in your plan, and how to make your vision a reality.
What are the essential components of your health and wellbeing plan?
- Knowing what you eat—refer to my food diary.
- Knowing why you eat.
- Understanding how the way you eat impacts on your health and wellbeing
- Embracing the basic nutritional qualities of whole foods—fruits and vegetables, wholegrains, protein foods, dairy and its alternatives and sources of oil
- Matching how and what you eat with your personal requirements.
- Selecting and preparing nutritious foods.
- Balancing your lifestyle—taking particular care with exercise, sleep, complete (abdominal) breathing and time for meditation and reflection.
- Building supportive relationships.
- Working in partnership with your healthcare practitioners.
- Identifying your goals and actions.
- Understanding the process of change.
- Living with and accepting change.
- Creating a toolkit to support you—passive and active past-times that nurture you.
Putting your health and wellbeing plan together
#1 Think about your vision for your health and wellbeing
Excerpt Eating for You
"A vision is a broad statement describing what you wish to achieve. Sharon shared her familiar story. She expressed that she often felt tired, was skipping her morning walk and had gained 5kg during the past 12 months. Sharon realised that she had been giving to others and neglecting her own needs. She said that her eating pattern had become erratic. Sharon's vision for her health included having sufficient energy to maintain a healthy body and mind and to enjoy her relationships with others. Think about your own situation, what are you aiming to achieve by introducing change into your life?
Your vision and goals concerning your eating habits need to sit within your vision for your total life. Whilst I believe that eating is central to health and wellbeing, other lifestyle factors need to support you too, such as adequate sleep. It is like the pieces of the jigsaw puzzle. Each lifestyle component contributes to the total picture. You won't enjoy the complete picture of health and wellbeing if you leave vital pieces out."
#2 Refer to the components of the health and wellbeing plan listed above
The essential components of your health and wellbeing plan are covered in the book, Eating for You. Some are introduced in recent blog posts (see links in text).
#3 Refer to the goals you have identified for this year
Last week we reflected on goals for 2016.
#4 Identify how much time you can free up in your day
Keep a log of how you use your time now. The simplest way is to record your commitments and activities in your diary. If you can, keep this for a week. Then, review your diary and see what commitments and activities that you can reduce or eliminate, to make time for your new activities.
# 5 Choose and commit to up to three goals
Excerpt from Eating for You
"Let's revisit your vision before you commence writing your goals. Ask yourself, "Do the priorities I have identified support my vision?" Some of the priorities you have written down will be written as goals and some will be actions. So what is the difference? Goals are written in a way that defines and measures the type and amount of change you are seeking. We will use Sharon's vision as an example 'To have sufficient energy to maintain a healthy body and mind and to enjoy relationships with others'.
One of Sharon's goals was to:
Goal: Increase my sleep to 8 hours per night.
Action: Stop watching TV and using the computer by 7.30pm.
Action: Have an aromatherapy bath before bed.
Action: Be in bed and prepared for sleep by 9pm."
#6 Put your new activities into your diary
Choose your new activities (or actions) and put them into your diary. As you can see from Sharon's example above, she created time for a bath by decreasing her TV viewing time and computer usage. These changes also supported an improved sleep routine.
Create a timeline to introduce your new activities. For example you might decide to decrease your TV viewing immediately, start walking three times per week in the second week of your plan, and in the third week you might start cooking one new recipe per week. This will help you to develop clarity around what your ideal day looks like.
Excerpt from Eating for You
"Your daily routine may be predictable or quite varied; especially if you travel frequently or work different shifts for example. Moving forward you need to establish a rhythm that allows for these variances. An ideal work day, putting in your health and wellbeing commitments first, might include:
6.00–6.30am meditation and yoga
6.30–7.15am shower, get dressed and eat breakfast
7.15-7.45am walk to the bus stop
8.30am Start work with a break mid morning
Midday Lunch with a break mid afternoon (do gentle exercise/ stretches)
4.45pm Review and update work task list
5.00pm Finish work
6.15–7.00pm Prepare and eat dinner
8.30pm aromatherapy bath
9.00-9.30pm In bed for sleep"
Eating for You guides you step by step along the path to creating your health and wellbeing plan. It helps you to uncover what you need—through knowing yourself, knowing your food and knowing how to introduce and live with change.

Extreme Event Solutions at Verisk (formerly AIR Worldwide) has revealed its estimates for the losses caused by the February 6 earthquakes in Turkey – with economic losses likely to exceed US$20 billion (approx. £16.4 billion) while industry insured losses are estimated to exceed US$1 billion.
The estimated figures are derived from the impacts of both the M7+ earthquakes that occurred on Feb 6, 2023, and results from Verisk indicate that the initial shock is the driver of the majority of the insured losses.
Commenting on the report, Bill Churney, president of Extreme Event Solutions, Verisk emphasised that the devastating earthquakes caused a tragic loss of life as well as extensive physical damage.
"The sizable difference between insured and economic losses—the protection gap—represents the cost of catastrophes to society, much of which is ultimately borne by governments," he said. "Increasing insurance penetration can ease much of the burden.
"There are solutions available that can enhance global resilience efforts including, emergency management, hazard mitigation, public disaster financing, risk pooling, and other government-led risk- and loss-mitigation initiatives."
A report identifying the steps taken to protect Turkey's people and infrastructure noted that the country has a high rate of earthquake occurrence. Since 1900, approximately 12 earthquakes of magnitude 5.0 and greater and one event of magnitude 6.0 and greater have occurred in Turkey each year.
Verisk highlighted that notable historical events in Turkey include the 1939 magnitude 7.9 İzmit earthquake, the 1999 magnitude 7.5 İzmit earthquake, and the 1999 magnitude 7.2 Düzce earthquake.
"Turkey has a long history of building codes and regulations that have been developed to ensure the safety and performance of buildings against earthquakes," the report identified. "Current codes reflect the latest advancements in building technology and seismic design practices almost in parallel with changes in the US seismic code.
"Despite these efforts, the seismic performance of buildings in Turkey during earthquakes has been mixed. Buildings complied with codes have performed relatively well, while many others have experienced significant damage and collapse during earthquakes."

For the storage and transportation of liquid hydrogen, you need a heavy cryogenic support system. The tank is cold enough to cause plugged valves and other problems. If you add insulation to prevent this, you will increase the weight of an already very heavy storage tank, adding additional costs to the system.17
Let's assume that a hydrogen car can go 55 miles per kg.18 A tank that can hold 3 kg of compressed gas will go 165 miles and weigh 400 kg (882 lbs).19 Compare that with a Honda Accord fuel tank that weighs 11 kg (25 lbs), costs $100, and holds 17 gallons of gas. The overall weight is 73 kg (161 lbs, or 8 lbs per gallon). The driving range is 493 miles at 29 mpg. Here is how a hydrogen tank stacks up against a gas tank in a Honda Accord (last column is cost):
|Amount of fuel||Tank weight with fuel||Driving Range|
|Hydrogen||55 kg @3000 psi||400 kg||165 miles13||$200021|
|Gasoline||17 gallons||73 kg||493 miles||$100|
According to the National Highway Safety Traffic Administration (NHTSA), "Vehicle weight reduction is probably the most powerful technique for improving fuel economy. Each 10 percent reduction in weight improves the fuel economy of a new vehicle design by approximately eight percent."
The more you compress hydrogen, the smaller the tank can be. But as you increase the pressure, you also have to increase the thickness of the steel wall, and hence the weight of the tank. Cost increases with pressure. At 2000 psi, it is $400 per kg. At 8000 psi, it is $2100 per kg.20 And the tank will be huge — at 5000 psi, the tank could take up ten times the volume of a gasoline tank containing the same energy content.
Fuel cells are heavy. According to Rosa Young, a physicist and vice president of advanced materials development at Energy Conversion Devices in Troy, Michigan: "A metal hydride storage system that can hold 5 kg of hydrogen, including the alloy, container, and heat exchangers, would weigh approximately 300 kg (661 lbs), which would lower the fuel efficiency of the vehicle."21
Fuel cells are also expensive. In 2003, they cost $1 million or more. At this stage, they have low reliability, need a much less expensive catalyst than platinum, can clog and lose power if there are impurities in the hydrogen, don't last more than 1000 hours, have yet to achieve a driving range of more than 100 miles, and can't compete with electric hybrids like the Toyota Prius, which is already more energy efficient and low in CO2 generation than projected fuel cells.22
Hydrogen fuel cells need a lot of platinum — far more than can be obtained if they were to become commercial (41).
Hydrogen is the Houdini of elements. As soon as you've gotten it into a container, it wants to get out, and since it is the lightest of all gases, it takes a lot of effort to keep it from escaping. Storage devices need a complex set of seals, gaskets, and valves. Liquid hydrogen tanks for vehicles boil off at 3–4 percent per day.23
Hydrogen also tends to make metal brittle.24 Embrittled metal can create leaks. In a pipeline, it can cause cracking or fissuring, which can result in potentially catastrophic failure.25 Making metal strong enough to withstand hydrogen adds weight and cost. Leaks also become more likely as the pressure grows higher. It can leak from un-welded connections, fuel lines, and non-metal seals such as gaskets, O-rings, pipe thread compounds, and packings. A heavy-duty fuel cell engine may have thousands of seals.26 Hydrogen has the lowest ignition point of any fuel, 20 times less than gasoline. So if there's a leak, it can be ignited by any number of sources.27 And an odorant can't be added because of hydrogen's small molecular size (SBC).
Worse, leaks are invisible — sometimes the only way to know there's a leak is poor performance.
One barrier to hydrogen is pipelines. There are currently 700 miles of hydrogen pipelines in operation—that is in comparison to 1 million miles of natural gas pipelines. To move to a nationwide use of hydrogen, safe and effective pipelines have to be developed. Tests have to be developed to test for the degradation that is likely to occur to the metals that can be caused by hydrogen weakening the pipeline.
According to former secretary of energy Steven Chu (39), hydrogen seeps into metal and embrittles it, and is a materials problem that has not been solved for decades and may never be solved.
Nor can hydrogen piggyback on nitrogen pipelines at less dangerous concentrations of 5 to 15% — it can't be extracted at the other end until pressure swing adsorption membranes are invented, and all impurities taken out so that fuel cells aren't damaged. Even if invented, renewable wind or solar would only be able to create excess electricity to make hydrogen for just part of the year. Pipeline operators won't want to install and remove expensive extraction equipment seasonally (40).
Working very closely with State weights and measures organizations, NIST has long maintained the standard for ensuring that consumers actually receive a gallon of gas every time they pay for one. Now NIST researchers are incorporating the properties of hydrogen in standards that will support the development of hydrogen as a fuel in vehicles. One of the challenges in the use of hydrogen as a vehicle fuel is the seemingly trivial matter of measuring fuel consumption. Consumers and industry are accustomed to high accuracy when purchasing gasoline. Refueling with hydrogen is a problem because there are currently no mechanisms to ensure accuracy at the pump. Hydrogen is dispensed at a very high pressure, at varying degrees of temperature and with mixtures of other gases (S.HRG. _PHONE_)
Canister trucks ($250,000 each) can carry enough fuel for 60 cars.28 These trucks weigh 40,000 kg, but deliver only 400 kg of hydrogen. For a delivery distance of 150 miles, the delivery energy used is nearly 20 percent of the usable energy in the hydrogen delivered. At 300 miles, that is 40 percent. The same size truck carrying gasoline delivers 10,000 gallons of fuel, enough to fill about 800 cars.29
Another alternative is pipelines. The average cost of a natural gas pipeline is one million dollars per mile, and we have 200,000 miles of natural gas pipeline, which we can't re-use because they are composed of metal that would become brittle and leak, as well as the incorrect diameter to maximize hydrogen throughput. If we were to build a similar infrastructure to deliver hydrogen it would cost $200 billion. The major operating cost of hydrogen pipelines is compressor power and maintenance.30 Compressors in the pipeline keep the gas moving, using hydrogen energy to push the gas forward. After 620 miles, 8 percent of the hydrogen has been used to move it through the pipeline.31
How much electricity would we need to make hydrogen for light-duty vehicles (Post 2017)?
At some point along the chain of making, putting energy in, storing, and delivering the hydrogen, we will have used more energy than we can get back, and this doesn't count the energy used to make fuel cells, storage tanks, delivery systems, and vehicles.32 When fusion can make cheap hydrogen, when reliable long-lasting nanotube fuel cells exist, and when light-weight leak-proof carbon-fiber polymer-lined storage tanks and pipelines can be made inexpensively, then we can consider building the hydrogen economy infrastructure. Until then, it's vaporware. All of these technical obstacles must be overcome for any of this to happen.33 Meanwhile, the United States government should stop funding the Freedom CAR program, which gives millions of tax dollars to the big three automakers to work on hydrogen fuel cells. Instead, automakers ought to be required to raise the average overall mileage their vehicles get — the Corporate Average Fuel Economy (CAFE) standard.34
At some time in the future the price of oil and natural gas will increase significantly due to geological depletion and political crises in extracting countries. Since the hydrogen infrastructure will be built using the existing oil-based infrastructure (i.e. internal combustion engine vehicles, power plants and factories, plastics, etc.), the price of hydrogen will go up as well — it will never be cheaper than fossil fuels. As depletion continues, factories will be driven out of business by high fuel costs35,36,37 and the parts necessary to build the extremely complex storage tanks and fuel cells might become unavailable.
The laws of physics mean the hydrogen economy will always be an energy sink. Hydrogen's properties require you to spend more energy than you can earn, because in order to do so you must overcome waters' hydrogen-oxygen bond, move heavy cars, prevent leaks and brittle metals, and transport hydrogen to the destination. It doesn't matter if all of these problems are solved, or how much money is spent. You will use more energy to create, store, and transport hydrogen than you will ever get out of it.
Any diversion of declining fossil fuels to a hydrogen economy subtracts that energy from other possible uses, such as planting, harvesting, delivering, and cooking food, heating homes, and other essential activities. According to Joseph Romm, a Department of Energy official who oversaw research on hydrogen and transportation fuel cell research during the Clinton Administration: "The energy and environmental problems facing the nation and the world, especially global warming,

Combinatorial evaluation system for thermal properties of glass materials using a vertical furnace with temperature gradient
Critical cooling rate Q for zinc tellurite glass system is
determined based on the time-temperature-transfer (T-T-T) diagrams,
which are compiled by analyzing the crystallized area in the glass
sample libraries annealed simultaneously by a furnace with
temperature gradient. This method reduces the laborious routine
work for preparation, which is needed in the conventional method.
Since the surface/volume ratio of the present samples is large,
their crystallization is mainly governed by heterogeneous
nucleation. Thus, the Q values in this study can be used as a
practical index for the glass products whose surface should be free
of being ground and/or polished, such as fire-polished lenses,
optical fibers and waveguides.

It's easy to see what's happening in the dining room but it's hard to see what's going on in the kitchen. According to the Centers for Disease Control and Prevention, 1 in every 6 Americans gets sick from food contamination each year. Consumers usually lack the information to knowledgeably choose where to eat based on the risk of food contamination.
Boston restaurants are required by law to be inspected on an annual basis. However, food inspection data is typically available in rare and elusive online datasets. They are not like Yelp or Carfax; they are tedious.
Food Sherpa is a data visualization that seamlessly displays inspection results and grades for all Boston restaurants. These grades are presented in a report card format with an A through F scale. The quantity and severity of a restaurant's five-year inspection history are used to assign the grades. This visualization can be used by any Boston restaurant-goer, to assist in making more informed decisions about where to eat out. Food Sherpa fills an integral gap in the awareness of restaurant consumers.
