Dhammayazika is located in Pwasaw region. in the southern part of Bagan. This temple was built by King Narapati Sithu. The name of the pagoda. Dhammayazika or Dhammarajika in Pali means "Pertaining the King of Law. The structure of Dhammayazika Pagoda has pentagonal terraces instead of the usual Bagan pagodas. the square base.
There are three receding terraces. ornamented with glazed Jataka plaques. On each side of the pagoda. there is a small temple housing an image of Buddha.
The usual practice in most temples was to have four images facing the cardinal points. representing the four Buddhas of the present world cycle who have already attained Enlightenment.
But in this pagoda the fifth temple is placed with the future becoming Buddha. All the five names of the Buddha are Kakusandha. Konagamana. Kassapa. Gotama and Metteyya. The inscription records say tht in 1197 King Narapatisithu received four holy relics from the King of Sri Lanka and that he built the pagoda in 1198 to enshrine the relics.

Most of the time, simply power cycling the TV solves the issue.
But if not working in your case, follow the bellow step-by-step guidelines.
How to Fix TCL Roku TV Stuck On Red Screen?
Step 1: Check the HDMI cable connections
While the HDMI connection itself is not directly responsible for this issue, a faulty or malfunctioning HDMI connection can create an indirect clash with the TV's firmware, resulting in difficulties loading the startup screen properly and getting stuck on a red screen.
That's why it's a good idea to check the HDMI connection.
Make sure that the HDMI cable is plugged into the right port and firmly connected to both the TV and the device.
Also, ensure that the HDMI cable is not bent or damaged.
Step 2: Perform an HDMI reset
For this, you need to take the help of "Power Cycling".
I know this is something no one wants to hear, but it really works!
- Completely disconnect the TV from the power outlet.
- Also, disconnect all HDMI devices connected to the TV.
- Wait for 5 minutes (Don't compromise).
- During this time, press and hold the TV's power button for about 30 seconds.
- Power the TV back on.
Once the TV has booted up, check if it's working properly now.
If not, proceed to the next step.
Step 3: Clean the inside components
Over time, dust and dirt accumulate inside the TV, especially around the parts that cool it down and the internal circuits.
When you turn on the TV or when it loads all the necessary software files before starting, all the different parts have to work harder than usual.
And when that happens, some of the capacitors that are responsible for starting up may work slowly or stop working completely.
The solution is pretty simple!
Use a screwdriver to open the back panel of the TV, and then gently clean all the components with a very soft brush. Be careful not to damage any capacitors or cut any wires.
Tip: Sometimes, this problem can also occur if any of the capacitors in the TV are damaged or burned out. When you open the TV to clean it, take a close look to see if you notice any bursts or burned-out capacitors. If you find one, it's likely the main cause of the problem, and you'll need to replace it.
Step 4: Factory Reset your TV
Resetting is a compelling method to restore a TV's firmware file to the default state and remove any type of malware or virus.
However, if power cycling doesn't fix the issue, reset your TV.
Hopefully, this will fix your problem by removing the TV's infected firmware file.
Remember: resetting will erase everything, including your data and settings.
- Remove all the cables, excluding the power cord.
- Then turn on your TV.
- Afterward, check your TV's lower part or back for the reset button.
- Once you locate it, take a ball pen and press and hold the reset button for at least 12 seconds.
The TV will turn off and then on automatically.
Once the startup screen comes up, release the reset button. Now check if the problem has been fixed or not.
Step 5: Update your TV software
As I mentioned earlier, the most common reason for a TCL Roku TV to be stuck on the startup screen is because the firmware is corrupted.
If resetting doesn't solve the issue, upgrading or downgrading the TV's firmware via a USB flash drive may help.
To update your TCL TV using a USB flash drive:
- First, download the latest firmware version from the TCL website. (Be sure to choose the correct model number for your TV)
- Right-click the downloaded firmware file, then select "Send To," "Extract" (or "Zip"), and the extraction program loads onto the screen.
- Connect a USB drive to your computer and copy the downloaded firmware file to the drive.
- Click "Start," "(My) Computer," then right-click the removable device icon and select "Eject." (Disconnect the USB flash drive from the USB port on the computer once the icon disappears.)
- power down the TCL Roku LCD TV, plug the USB flash drive into the USB port on the TV and then power the TV on.
Once you insert a USB flash drive into the TV, it will automatically recognize the device and start uploading the data onto the TV.
When the upload process is done, the TV will display a notification on the screen, reminding you to remove the USB flash drive.
Q: Is there a way to prevent the TCL TV from getting stuck on the startup screen?
Yes, regularly updating the software, ensuring proper ventilation for the TV, and avoiding overloading the TV with too many apps can help prevent your TV from getting stuck on the red screen.
Q: Does the red screen issue affect the performance of other connected devices?
No, the red screen issue on the TCL Roku TV should not affect the performance of other connected devices, but it is always a good idea to disconnect them before troubleshooting the TV.
Q: Can a faulty HDMI cable cause my TV to get stuck?
Yes, a faulty HDMI cable can cause issues with your TCL Roku TV, including getting stuck on the red screen.
Try using a different HDMI cable or disconnecting all cables from your TV and see if the red screen issue persists.
Q: How long does it take for a TCL Roku TV to boot up?
Typically, it should take less than a minute for your TCL Roku TV to boot up and display the home screen.
However, if it gets stuck on the red screen, it may take longer or not boot up at all.

The Significance of Saugus Iron Works
To the United States and the World:
Saugus lron Works is a reconstruction of the ﬁrst successful, integrated iron works in the New World. It produced wrought iron and cast iron products from 1646 to approximately 1670, utilizing the most advanced iron making technology in early Colonial times. On April 5th, 1968 the site was renamed Saugus Iron Works National Historic Site and became part of the National Park System because of its significance to the character, development and history of the United States.
Elements of Significance:
The Massachusetts site is nationally signiﬁcant because it is considered the birthplace of the iron and steel industry in Colonial America, initiating and sustaining an advanced iron making technology in the New World. The subsequent dispersal of former workers and their descendants to other parts of Colonial America, where they established other iron producing centers, was critical to the development of industry and technology in the emerging country. Saugus Iron Works demonstrates the crucial role of iron making to the 17th century settlement of the Colonies and its legacy in shaping the history of the nation.
Restored by noted preservationist Wallace Nutting in 1916, the site's 1680's Iron Works House is a prominent example of the Colonial Revival and Twentieth- Century American Preservation Movement.
The National Register of Historic Places calls the Saugus lron Works "the ﬁrst chapter in America's book." With its requirement for a large labor force, the iron works served as a conduit, fowarding the movement of technology and people from the Old World to the New. Through the experiences of Puritans, English freemen, and Scots prisoners engaged for its operation, the iron works traced the British immigrants' journey in the New World, and recorded their stories of assimilation.
Saugus lron Works serves as a learning laboratory to understand and explore the stories of archaeology, Native American settlement, and life in the Massachusetts Bay Colony. The interrelationship of humans in the natural environment and the ecological effects of industrial development are clearly evident and understood.
In recognition of its signiﬁcance as the birthplace of the iron and steel industry in America, the American iron and Steel institute reconstructed the primary elements of the original iron works after extensive archaeological excavations beginning in the 1940s. Saugus lron Works Restoration opened to the public in 1954 and was operated as a private museum until the National Park Service began its administration "to preserve in public ownership the ﬁrst sustained integrated ironworks in the Thirteen Colonies." The site was donated by the lron and Steel institute.

BACKGROUND: Cabbage may become contaminated with enteric pathogens during cultivation. Using multiple cabbage cultivars at two maturity stages (small plants or plants with small heads) in growth chamber studies, the fate (internalization or surface survival) of Salmonella and Escherichia coli O157:H7 (0157) were examined in conjunction with any potential relationships to the plant's antimicrobial content.
RESULTS: Internalized Salmonella was detected in cabbage within 24 hours with prevalence ranging from 62% (16 of 26) for the 'Super Red 80' cultivar to 92% (24 of 26) for the 'Red Dynasty' cultivar. The fate of Salmonella and O157 on small cabbage plants over nine days was significantly affected by cultivar with both these pathogens surviving the least and most on the 'Capture' and 'Farao' cultivars, respectively (P < 0.05). Survival of O157 was slightly higher on cabbage heads for O157 than small plants suggesting that the maturity stage may affect this pathogen's fate. An inverse relationship existed between antimicrobial levels and a pathogen's fate on cabbage heads (P < 0.05).
CONCLUSIONS: The fate of pathogens varied with the cabbage cultivar in growth chamber studies highlighting the potential to explore cultivar in field studies to reduce the risk of microbiological contamination in this crop.

Probabilistic Analysis of Random Test Generation Method for Irredundant Combinational Logic Networks
Issue No. 07 - July (1975 vol. 24)
P. Agrawal, Department of Electrical Engineering-Systems, University of Southern California
In this paper the random test generation method for large logic circuits is analyzed. Formulas for the detection probability and the number of random input patterns required to complete the test generation with a high probability are obtained for an irredundant fan-out-free combinational network tree consisting of identical n-input NAND gates. The quantitative estimates for the number of random input patterns required for test generation appear to depend upon the number of levels in the circuit and the fan-ins of the gates. Experimental results for actual computer logic circuits are given and show the validity of the approach.
Combinational networks, detection probability, fault detection, path sensitizing, probabilistic analysis of logic, random test generation.

Chain steel chain
The chain net is a cellular structure made using a unique plaiting technology and consisting of steel rings, which in turn are also woven by using one of the technologies (continuous wire rope). At the moment the steel chain mail chain is an alternative economical and practical choice as opposed to morally obsolete, rather expensive and rapidly destroying reinforced concrete structures.
Mail chain properties:
- high resistance to oxidation and subsequent destruction as a result of corrosion;
- wide range of operating temperatures, including their significant gradations;
- immunity to ultraviolet action;
- increased tensile strength;
- comparatively low weight;
- long service life.
The material from which the above product is made is galvanized steel wire rope.
Technical characteristics of wire:
- The grade of steel is from 55 to 85;
- density of zinc coating - from 150 to 220 g / m2;
- resistance to tearing (temporary) - from 150 to 180 kgf / mm;
- diameter - from 2 to 5 mm.
Technical characteristics of the wire ring:
- inner diameter - 350 or 420 mm;
- the number of turns - 7, 12 or 19;
- tensile force - 22 tons with a cross-sectional diameter of 12 mm, from 50 tons at a diameter of 19.5 mm.
Types of binding mail chain:
- 4-pin on the diagonal;
- 4-pin vertical;
- 6-pin connector.
When using any type of knitting from the above, a continuous mesh fabric is obtained, whose annular cells are not fixed firmly at the interlacing points. The steel chain mail chain is capable of withstanding sufficiently large dynamic loads and is an excellent choice as a flexible and reliable design, effectively absorbing the destructive energy of avalanches, landslides, mudflows, etc.
The main advantages of using chain mesh:
- impeccable quality;
- high reliability of finished structures;
- Application in a terrain characterized by a complex topography;
- economical expenditure of funds for the acquisition, installation and subsequent operation;
- the lack of linking the work to the climate and season;
- shortening the terms of design and delivery of the facility;
- service life - from half a century or more;
- affordable price.
The mail chain network is especially in demand when creating protection systems for highways and railroads located in mountainous areas and settlements from the effects of natural disasters such as snow avalanches, rock falls, mudflows, landslides, etc. In addition, this geo-product is used to protect coastal hydro objects and beaches from the invasion of representatives of marine fauna.

MI Farm to School awards funds to support 26 grantees with local purchasing efforts in K-12 schools/districts and early childhood programs
The MI Farm to School Grant Program is a competitive statewide grant program that provides funds to K-12 schools/districts and early childhood programs serving vulnerable children to plan for and implement local food purchasing. The 2016-2017 grant year will be its 7th in operation, and adds to the previous nearly $160,000 that has been granted by the program MI Farm to School Grant Program to support local food purchasing throughout the state.
In the 2016-2017 grant year, 12 K-12 schools/districts and 14 early childhood programs will help support nearly 24,000 children in accessing fresh, local food through farm to school programs. Grantees are spread throughout 13 counties and include both rural and urban K-12 districts, charter schools, family day care homes, Head Start and Great Start Readiness programs, child care centers, and a residential child care institute.
While the end goal of each program is to increase its purchasing of local food, each grantee is going about it in a uniquely different way. Their efforts showcase the breadth and diversity of farm to school programming and highlight some really innovative approaches. Among other objectives, grantees this year are aiming to:
· Develop and strengthen relationships with local growers
· Increase local milk purchasing
· Increase sourcing of locally raised proteins
· Engage new community partners to build strong farm to school teams
· Increase storage capacity for locally grown foods

You know that the title of the book is The Golden Compass, but let's not forget that it's also the first book in the series called His Dark Materials.
The golden compass, also known as an "alethiometer," is a gadget given to Lyra by the Master of Jordan College at Oxford. The device is powered by Dust and can be used to gain insight into any number of questions. As Farder Coram tells us in Chapter 7, "aletheia" is Greek for "truth," so "alethiometer" means "truth measure" (7.118). It's a bit ironic that the designated keeper of this particular alethiometer is Lyra, who is known for telling whoppers.
Why title the book The Golden Compass? Maybe it's because Lyra's growing skill with this instrument of the divine proves to the reader that there's something very special about her – and it allows her to harness a power of her own.
The titles of the other two books in the trilogy also feature objects: The Subtle Knife and The Amber Spyglass.
P.S. The original title for this book is Northern Lights. Actually, it's only published as The Golden Compass in North America. The original title shifts the focus away from the alethiometer and toward the scene under the northern lights where Lord Asriel creates a bridge to another world. Which title do you like better?
The phrase "His Dark Materials" is a line from Book II of Milton's Paradise Lost, which you can read all about on Shmoop. For more on the phrase "His Dark Materials," zip over to our section on the novel's epigraph, which contains the phrase.
In The Golden Compass, those "Dark Materials" presumably refer to Dust, which – as Lord Asriel tells us in Chapter 21 – the Church interprets as evidence of original sin. For more on that topic, head over to "Symbolism, Imagery, Allegory: Dust (and Original Sin)."

Asbestos is still present in some 80% of the Flemish schools in Brussels, according to Schoolgroep Brussel (SGB), the group representing the education system of the Flemish Community, Belga reports.
The group keeps an inventory of asbestos in schools, which is updated every year. It has around 100 schools under its responsibility, of which six schools in 2019 had asbestos removed. The substance is now known to be carcinogenic, but was widely used as a fire retardant in construction – of homes as well as public buildings – as late as the 1990s.
"There is no fixed plan for removing asbestos from buildings," Karin Struys, spokesperson for the SGB, told Bruzz. "Whenever there's a risk then of course immediate removal is carried out. And in cases of renovations, big or small, asbestos is always removed."
The process of removing asbestos is in itself extremely dangerous as it releases fibres into the air, so it is always carried out by specialist contractors.
Protection at present takes two forms. First, the inventory is kept up to date each year, and can be consulted by prevention experts from the SGB. Second, prevention advisers within schools undergo training in how to recognise asbestos and how to deal with it. But the question of how to deal with it costs money.
"Even small-scale renovations cost the school group about €70,000 a year just for the removal of asbestos," Struys said. "And the group can count on only 50% subsidies from the community education system. Unfortunately we don't get the kind of extra financial support from OVAM [the public waste agency in Flanders] that school groups in Flanders enjoy. It would be a good thing if [Brussels environment agency] Leefmilieu Brussel could pay out extra subsidies to the Dutch-speaking community schools in Brussels."
Figures for the schools falling under the responsibility of the Catholic education system were not available, Belga said.

text: Azimuthal structuring is usually observed within the brightening auroral substorm onset arc; such structure has been linked to the exponential growth of electromagnetic ultralow‐frequency (ULF) waves. We present a case study investigating the timing and frequency dependence of such ULF waves on the ground and in the near‐Earth magnetotail. In the magnetotail, we observe an increase in broadband wave power across the 10‐ to 100‐s period range. On the ground, the arrival times spread from an epicenter. The onset of longer period waves occurs first and propagates fastest in latitude and longitude, while shorter periods appear to be more confined to the onset arc. The travel time from the spacecraft to the ground is inferred to be approximately 1–2 min for ULF wave periods between 15 and 60 s, with transit times of 60 s or less for longer period waves. This difference might be attributed to preferential damping of the shorter period waves, as their amplitude would take longer to rise above background levels. These results have important consequences for constraining the physics of substorm onset processes in the near‐Earth magnetotail and their communication to the ground.

Confluence Journal Service
Confluence 5.6 and later
Confluence Journal Service provides access to journals that are durable FIFO queues with the following behavior:
- Journal entries are processed on all nodes when running in a cluster.
- Entries are durable - receiving nodes do not need to be running when the event is queued.
- New cluster nodes can process entries that were queued before the node was created.
- Entries are guaranteed to be delivered in the same order that they were added.
- Journals are bounded in size by the age of the entries, i.e. entries that are older than a set limit are cleared regularly.
Journals are accessed through
Each journal has its own journal identifier. Journals do not need to be explicitly created or removed by client code.
Creating journal entries
Journal entries have five fields:
id: Monotonically increasing unique identifier for the entry. It is assigned automatically when an entry is queued. An entry with a larger id is considered to have happened after entries with a smaller id.
journalId: Identifies the journal that the entry belongs to. Maximum length is 255 characters. May only contain lower-case letters (English alphabet), digits, underscores and dot characters.
creationDate: Point in time when the entry was created. It is assigned automatically when an entry is queued.
type: Type of the entry. This is a journal specific free-form field. Maximum length is 255 characters.
message: Message of the entry. This is a journal specific free-form field. Maximum length is 2047 characters.
Processing journal entries
Entries are processed by calling
JournalService#processEntries method. It has the following signature:
processEntries will call the given
entryProcessor function with at most
maxEntries entries which have the given
entryProcessor will in turn create an instance of
EntryProcessorResult that contains a
result value that is returned to the caller of
processEntries. Depending on
entryProcessor return value, four things can happen on next call to
EntryProcessorResult.success(result)causes none of the processed entries to be processed again.
EntryProcessorResult.partial(result, lastSuccessfulId)causes entries with an id larger than
lastSuccessfulIdto be processed again.
EntryProcessorResult.failure(result, failedEntryId)causes entries with an id equal to or larger than failedEntryId to be processed again.
- Throwing a
RuntimeExceptioncauses all the entries to be processed again.
Entries should be processed in small batches (i.e. small
maxEntries value) in order to reduce memory consumption during the processing. The following example shows how to process all the entries in batches. It also demonstrates how to ensure that already processed entries will not be processed again if a
RuntimeException is thrown when processing an entry.
JournalService also offers methods for retrieving current entries in the journal without removing them from journal (
peek), removing entries from journal without processing them (
reset) and counting the number of entries in the journal (
Usage in cluster
Each cluster node keeps track of the entries that have been processed on the same node. This means each entry is processed on all cluster nodes.
A compatibility library is available for plugins that want to use Journal Service but need to stay compatible with older Confluence versions. In older versions of Confluence (5.5 and earlier) entries are stored in main memory. This means that unprocessed entries will be forgotten during restart and that entries are only processed on the local node in a cluster.
In addition to maven dependency, the compatibility library depends on Journal Service on Confluence 5.6 and later, thus related packaged need to be dynamically imported in OSGi instructions section in the plugin pom.xml:
com.atlassian.confluence.journal.compat.JournalServiceFactory is the entry point to the compatibility library, and it can be used to get a JournalService instance:
Normally tests would invoke
JournalService#waitForRecentEntriesToBecomeVisible() after running code that added entries and before running code that needs to process those entries. If there are a lot of tests like this, the wait time can become significant. The following example code shows how to use the
com.atlassian.confluence.test.JournalManagerBackdoor service for temporarily disabling this wait. It should only be used in test code.

In 2018, Mayflower Primary School became the designated school for students with hearing loss. The school adopts a co-teaching model where a mainstream teacher and a specialised teacher jointly plan, coordinate, and deliver instruction to a diverse group of students. The co-teaching model promotes the inclusion of students with hearing loss to access the national curriculum within a regular education classroom.

text: This study proposes a radial basis function network (RBFN) controlled three-phase induction generator (IG) system using ac-dc and dc-ac power converters. In this study, first, the indirect field-oriented mechanism is implemented for the control of the IG. The electric frequency of the IG is controlled using the indirect field-oriented control mechanism. Then, an ac-dc power converter and a dc-ac power inverter are adopted to convert the electric power generated by a three-phase IG from variable-frequency and variable-voltage to constant-frequency and constant-voltage. Moreover, two on-line trained RBFNs using backpropagation learning algorithm with improved particle swarm optimization (IPSO) are introduced as the regulating controllers for both the dc-link voltage and the ac line voltage of the dc-ac power inverter. The IPSO is adopted in this study to adapt the learning rates in the backpropagation process of the RBFNs to improve the learning capability. By using the proposed RBFN controller with IPSO, the IG system can employ for stand-alone power application effectively. Finally, some experimental results are provided to show the effectiveness of the proposed IG system.

When To Come
The climatic conditions of Nepal vary by the geographical conditions, topography and the altitude. Nepal has climates ranging from tropical to the arctic. The low-land Terai regions have the least elevation and also consist of the lowest region of Nepal which is at 70m from the sea level. The maximum altitude of the Terai region is 305m. The mid-lands or the hilly region have a pleasant weather almost throughout the year. The mountains that lie above 3300 meters have an alpine climate where the temperature is very low in the winter.
September, October and November (Autumn):
This is the best season for trekking in Nepal. The weather is lively and pleasant and you can enjoy clear views of the mountains. The trekking routes are full of adventurers and trekkers in this season.
March April and May (Spring):
This comes only next to the Autumn in terms of popularity. The temperature is moderate and the rhododendrons in full blossoms can be sighted. The mountains can also be viewed with great clarity.
June, July and August (Summer):
This is the best season to trek in Nepal if you are planning on a trek to upper Mustang, Annapurna conservation area, Upper Manang, Manaslu or Upper Dolpo region. These rain shadow areas aren't affected by the monsoon because of the high mountains. Researchers and botanists prefer this season for trekking. You may need to carry insect repellents and raincoats with you.
December, January and February (Winter):
Winters are very cold in the high mountains. These are suitable for trekking in the lower altitudes of 3500 meters.

C# Example Code to Save and Resize Images from your Database to a System Folder
In this example I will show how to use C# in a WebForm to read out a series of pictures from a database table, resize the pictures to a standardized width, and then to save each image as a JPEG to a folder on your local file system. The code assumes that the pictures are coming from your database as JPEG format images, but you can easily adjust the code to dynamically save each image by its type if you have this data stored in your database.
Step-by-Step Code Walkthrough
To start, we set up a SQL connection to the database, and then loop through the results using a DataReader. Each image from the SQL Server database is read out of the database as a byte array, which is then converted to an Image object so that we can better manipulate it in code:
imagedata = (byte[])reader[0];
System.Drawing.Image tmpOriginalImage = System.Drawing.Image.FromStream(new System.IO.MemoryStream(imagedata));
Once we have the original image from the database, we want to standardize the width. In this example we will standardize each variable-sized image to 140 pixels wide. This naturally also involves adjusting the height of each image by the same aspect ratio. The scale of adjustment is calculated as:
double dblScaleImg = (double)intDesiredWidth / (double)tmpOriginalImage.Width;
Now that we have the scale, we will set up an empty BitMap image container with the correct dimensions for the image that we want to create and save:
Graphics tmpGraphics = default(Graphics);
 Bitmap tmpResizedImage = new Bitmap(Convert.ToInt32(dblScaleImg * tmpOriginalImage.Width), Convert.ToInt32(dblScaleImg * tmpOriginalImage.Height));
 tmpGraphics = Graphics.FromImage(tmpResizedImage);
So far so good! But now comes the most important part; resizing the original image into our new image container with minimal distortion. To do so we can set a number of different image scaling options that are described in detail in this article on MSDN. In our code example we will use the HighQualityBilinear scaling option, which is appropriate for handling images that are scaled or rotated:
tmpGraphics.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBilinear;
Now that our graphics object is properly set up, and our scaling dimensions are ready to be calculated, we set the original Image from our database into our new graphics object:
 tmpGraphics.DrawImage(tmpOriginalImage, 0, 0, tmpResizedImage.Width + 1, tmpResizedImage.Height + 1);
That completes our task of creating a new, standard-sized image from our original database object. The final step is to save our new image to our file system:
 System.Drawing.Image imageOut = tmpResizedImage;
 imageOut.Save("C:\\PicturesFolder\\testImage" + counter + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
As you can see, once you are familiar with the concepts and libraries, manipulating images in C# is quite straightforward. Have a look below at a fully functioning example of the concepts we just stepped through.
The Example Code
Here is a functional example of a simple ASP.NET WebForm with a button control on it. When the user clicks the button, a method is called which contains the script to save images from a database table to a folder on the local file system. As I mentioned, the process also involves resizing each image to a standardized width and corresponding height based on the image's original aspect ratio.

What's the difference between being an administrator user and root user on a Mac?
What can one do that the other can't, if anything?
This article might be of interest.
Enabling and using the "root" user in Mac OS X
"About the root user
The user named "root" is a special user in UNIX-style operating systems that has read and write privileges to all areas of the file system. The root user should only be used for specific administration or monitoring tasks. After completing a task as the root user, you should log out of Mac OS X and log back in using a normal or administrator account. You should disable root access if you do not use it often.
The root user does not appear in Users or Accounts preferences.
Important notes
Only the owner of a computer or its designated administrator(s) should have an administrator account or the root password.
Any user with an administrator account can become the root user or reset the root password.
A root password should be difficult to guess, containing both numbers and letters within the first eight characters.
A root user has the ability to access other users' files.
The root user has the ability to relocate or remove required system files and to introduce new files in locations that are protected from other users."
A root user can screw things up much more easily. You can access pretty much everything as a root user, including other users' files. The training wheels are off, and you can change or delete files with impunity, which can be a very bad thing if you delete or change the wrong thing. Be very careful, and don't do things while you are poking around as a root user unless you understand the consequences.

Oxford's university challenge: describe this cactus
Interviewers say their pointed questions about cacti help to find students who think rather than merely recite facts
A cactus. Describe... Photograph: Getty
Teenagers being interviewed for a place at Oxford might be handed a cactus and asked to describe it, or asked whether someone who risks their life in an extreme sport is a hero or a fool, according to sample questions released by the university today in an attempt to demystify its admissions procedure.
Candidates applying to study music might be asked what kind of musical instrument they would invent, while applicants for English literature might be asked why Coronation Street's 50th anniversary would be of interest to a scholar.
The university published details of the sample interview questions to help explain the reasoning behind apparently bizarre inquiries from admissions tutors.
The interviewer who set the cactus question, Martin Speight, of St Anne's College, said: "We give the student a cactus in a pot and a close-up photo of the cactus's surface structure and ask them to describe the object in as much detail as possible using the plant and the photo. We are looking for observation, attention to detail, both at the large and micro scale."
Candidates seeking a place on an undergraduate degree in biological sciences are expected to deduce why the cactus is bulbous, or why it has a particular array of spines.
"There will frequently be more than one logical answer to these questions, and we are likely to follow one answer with another question – for example: 'The big spines are to stop the cactus being eaten, yes, but by what sort of animals?'," Speight said.
"We would also bring in more general questions at the end of the cactus discussion such as what are the problems faced by plants and animals living in very dry habitats such as deserts."
The Coronation Street question is intended to show that the techniques of literary criticism can be applied to other media and open up discussion about storytelling, collaborative writing and how a writer such as Dickens can move from being regarded as "popular" to being accepted as part of the canon.
Candidates for psychology might be asked what is "normal" for humans. Dave Leal, of Brasenose College, said: "There were various ways that this question might be approached, but some approach that distinguished the normal from the statistical average was a good start. Issues such as whether normality is to be judged by biological factors that might be held to be common to humans, or whether it's normal within a particular culture or at a particular period of history, might also be worth addressing."
Mike Nicholson, director of undergraduate admissions at Oxford, said interviews were meant to replicate Oxford's tutorial system, encouraging students to think rather than recite facts.
"There are many myths surrounding Oxford interviews, and they can be the most anxiety-provoking part of the Oxford application process for students. These questions show that the interviews are not designed to see how quickly students get the 'right' answer or show off specialist knowledge, but to gauge how they respond to new ideas."
Oxford's selection process also involves assessing potential through aptitude tests, written work, exam grades and references.

Isn't it odd that the word for "father" in Spanish ("padre") and Sanskrit ("pitru") sound similar? Especially given the geographic and cultural barriers that separate the two languages? As this episode of The Intersection discovers, there's a reason these languages can sound similar, and what's more, there's actually a way to trace the pronunciations of modern words, sometimes going back 8,000 years. Tune in to know more about the granddaddy of modern Indo-European languages and how a story may have sounded thousands of years ago.

African Update on Modern-Day Slavery in Saudi Arabia
January 16, 2016
Again, this is another piece I'm putting up in response to the Saudi's foreign minister, al-Jubair, urging the rest of the world to respect Saudi Arabia's death penalty, 'because it's the law'.
This isn't about the Saudi death penalty, but another blemish on theirs and the world's culture and history: slavery.
It's a piece from the African news show, Africa Update, on present day slavery in Saudi Arabia. The presenter states that although slavery was officially banned in 1962, 300,000 slaves remained after its official abolition. And slavery continues today in the form of the Kafala system, or sponsorship, under which Saudi Arabia imports domestic servants and labourers. These are ruthlessly exploited. They typically work between 15-20 hours a day, with no rest days. If they run away, adverts are placed for their apprehension and return, as in the days of real, open slavery. If they complain or resist, they may suffer brutal maltreatment. Some of these domestic workers have even been killed. The Indonesians banned their people from working in Saudi Arabia after one or two Indonesian maids were killed by their masters. And just as shocking, a Saudi man placed an advert in one of the papers for a male slave he was selling, who had been castrated.
The presenter therefore urges her fellow Africans not to go to Saudi Arabia, unless they have a secure, well-paid job, where they will not be subject to such maltreatment, or have been given professorships at a Saudi university. She wonders how long the Saudis will continue to abuse Africans like this, and states that someone should complain to them.

Take the 2-minute tour ×
I'm learning about generators and conservation laws and have derived the equation (1)
$$[Q,A]=-i\hbar f(A)$$
which is satisfied by the observable generator $Q$ for a transformation group with elements of form
The lecture notes I'm reading say that this equation (1) defines $Q$ provided we know $f(A)$ for all observables $A$. Why is this true mathematically? And what does all observables mean?
The example in the notes applies it to transformations along the $k-$axis for a system of $r$ particles, obtaining
$$[Q,\hat{x}_i^r]=-i\hbar\delta_{ik}$$ $$[Q,\hat{p}_i^r]=0$$
It then states that $Q = \hat{P}_k=\sum_r \hat{p}_k^r$. This is obviously a solution, but do I know that it's the only one?
Many thanks in advance.

The statement is not correct, as $Q'=Q+g(A)$ satisfies (for an arbitrary function $g$) the same commutation relation. Thus you need to pay attention to the additional conditions posited in the context of your source.
share|improve this answer
What might be some typical additional conditions? How does it relate to the example perhaps? Many thanks! – Edward Hughes Aug 16 '12 at 8:46
I don't know; each context is different. Maybe the source doesn't make use of the uniqueness but just needs some solution. Then sloppiness in the writeup is a sufficient explanation. – Arnold Neumaier Aug 16 '12 at 8:50
Okay thanks. So we have an infinity of possible conserved quantities then? – Edward Hughes Aug 16 '12 at 9:03
There is always an infinity of conserved quantities since if $A$ and $Q$ are conserved then any function of $A$ and $Q$ is also conserved. One is therefore interested in independent conserved quantities, or in additively conserved quantities. – Arnold Neumaier Aug 16 '12 at 9:23

If a group has an irreducible representation on some vector space, then Schur's lemma says the only operators on that vector space which commute with every element of the group are the scalar operators. From this, If A and B have the same commutation relations with every element of the group, then $A-B$ commutes with everything, and thus must be a scalar. Therefore, the commutation relations determine everything up to the addition of a scalar (ie. up to central extension).
share|improve this answer
Very many thanks for this. Do you know of any references where I could read up on this irreducible representation stuff, because I haven't come across it before? Obviously I could look at Wikipedia, but a particular reference with QM in mind would be better! – Edward Hughes Aug 15 '12 at 21:30
No problem. For basic representation theory I like Fulton and Harris' "First Course in Representation Theory". For physical applications, the representation theory of finite groups is a bit of a detour though. For stuff focused on Lie gadgets I like Kirillov's book, which also has the advantage of being freely available online. As for stuff with a focus on quantum, I'm not really sure. I know Peter Woit has written some things about quantum mechanics and representation theory, but I think it is more about "geometric quantization" and would probably not be useful to you. – Ryan Thorngren Aug 15 '12 at 21:37
Actually, I think the greatest reference (or reading guide, perhaps) is John Baez's This Weeks Finds. He talks about representation theory, quantum mechanics, and much much more in a very informal (but informa*tive*) style. – Ryan Thorngren Aug 15 '12 at 21:40

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."

Harry Potter and the Order of the Phoenix Theme of Hate
We've seen a lot of bigotry in the Harry Potter series before. Draco Malfoy calls Hermione a Mudblood, meaning that she's a magic-user with non-magical parents. Then there's the Death Eater "prank" at the beginning of Book 4, when they levitate a Muggle family through the campground at the Quidditch World Cup because they enjoy torturing Muggles. But the hatred in Harry Potter and the Order of the Phoenix has a slightly different character.
Professor Umbridge hates half-humans, so she also has racial prejudice. But her hatred is largely aimed at people who disrespect her authority. Professor Umbridge loves rules. When she first comes in to the classroom, she insists that the students answer her with a full, "Yes, Professor Umbridge" or "No, Professor Umbridge." She wants them to show their obedience to her at all times. And when a student – ahem, Harry – doesn't immediately obey her, she turns the most terrifying loathing onto them. The thing is, Professor Umbridge's name is notably close to "umbrage," meaning to take offense. Everything offends Professor Umbridge, and she hates anything that offends her. So, by association, Professor Umbridge pretty much hates everything. And her hatred sours the whole atmosphere of Hogwarts throughout Book 5.
Questions About Hate
- We see several different examples of magical creatures hating humans in Book 5. On what grounds do these creatures claim to hate humankind? Do the different magical species we see in the novel hate humans for the same reasons? Why does J.K. Rowling take care to represent this hatred in Book 5?

How does Ada, Java and Python compare with each other when they are used to connect to a database? This was the main motivation for me to write the <a href="_URL_ Benchmark and write this article.

The database also has a serious impact on such benchmark and I've measured the following three famous databases:

<a href="_URL_

<a href="_URL_

<a href="_URL_

The purpose of the benchmark is to be able to have a simple comparison between these different databases and different programming languages. For this, a very simple database table is created with only two integer columns one of them being the primary key with auto increment. For example the <a href="_URL_ table is created with the following SQL:

 CREATE table test_simple ( id INTEGER PRIMARY KEY AUTOINCREMENT, value INTEGER )

The database table is filled with a simple <tt>INSERT</tt> statement which is also benchmarked. The goal is not to demonstrate and show the faster insert method, nor the faster query for a given database or language.

Benchmark

The SQL benchmarks are simple and they are implemented in the same way for each language so that we can get a rough comparison between languages for a given database. The <tt>SELECT</tt> query retrieves all the database table rows but it includes a <tt>LIMIT</tt> to restrict the number of rows returned. The query is executed with different values for the limit so that a simple graph can be drawn. For each database, the SQL query looks like:

 SELECT * FROM test_simple LIMIT 10

The SQL statements are executed 10000 times for <tt>SELECT</tt> queries, 1000 times for <tt>INSERT</tt> and 100 times for <tt>DROP</tt>/<tt>CREATE</tt> statements.

Each SQL benchmark program generates an XML file that contains the results as well as resource statistics taken from the <tt>/proc/self/stat</tt> file. An Ada tool is provided to gather the results, prepare the data for plotting and produce an Excel file with the results.

Python code

 def execute(self): self.sql = "SELECT * FROM test_simple LIMIT " + str(self.expect_count) repeat = self.repeat() db = self.connection() stmt = db.cursor() for i in range(0, repeat): stmt.execute(self.sql) row_count = 0 for row in stmt: row_count = row_count + 1 if row_count != self.expect_count: raise Exception('Invalid result count:' + str(row_count)) stmt.close()

Java code

 public void execute() throws SQLException { PreparedStatement stmt = mConnection.prepareStatement("SELECT * FROM test_simple LIMIT " + mExpectCount); for (int i = 0; i < mRepeat; i++) { if (stmt.execute()) { ResultSet rs = stmt.getResultSet(); int count = 0; while (rs.next()) { count++; } rs.close(); if (count != mExpectCount) { throw new SQLException("Invalid result count: " + count); } } else { throw new SQLException("No result"); } } stmt.close(); }

Ada code

 procedure Select_Table_N (Context : in out Context_Type) is DB : constant ADO.Sessions.Master_Session := Context.Get_Session; Count : Natural; Stmt : ADO.Statements.Query_Statement := DB.Create_Statement ("SELECT * FROM test_simple LIMIT " & Positive'Image (LIMIT)); begin for I in 1 .. Context.Repeat loop Stmt.Execute; Count := 0; while Stmt.Has_Elements loop Count := Count + 1; Stmt.Next; end loop; if Count /= LIMIT then raise Benchmark_Error with "Invalid result count:" & Natural'Image (Count); end if; end loop; end Select_Table_N;

The benchmark were executed on an Intel i7-3770S CPU @3.10Ghz with 8-cores running Ubuntu 16.04 64-bits. The following database versions are used:

MariaDB 10.0.36

PostgreSQL 9.5.14

Resource usage comparison

The first point to note is the fact that both Python and Ada require only one thread to run the SQL benchmark. On its side, the Java VM and database drivers need 20 threads to run.

The second point is not surprising: Java needs 1000% more memory than Ada and Python uses 59% more memory than Ada. What is measured is the the VM RSS size which means this is really the memory that is physically mapped at a given time.

The SQLite database requires less resource than others. The result below don't take into account the resource used by the MariaDB and PostgreSQL servers. At that time, the MariaDB server was using 125Mb and the PostgreSQL server was using 31Mb.

Speed comparison

Looking at the CPU time used to run the benchmark, Ada appears as a clear winner. The Java PostgreSQL driver appears to be very slow at connecting and disconnecting to the database, and this is the main reason why it is slower than others.

It is interesting to note however that both Java and Python provide very good performance results with SQLite database when the number of rows returned by the query is less than 100. With more than 500 rows, Ada becomes faster than others.

With a PostgreSQL database, Ada is always faster even with small result sets.

Historic England has awarded a grant of £400,000 towards the repair of Grade I listed Becket's Chapel in Wymondham.
The chapel, dedicated to St Thomas à Becket, is thought to have been founded in the late 12th century by the son of William d'Aubigny, founder of Wymondham Abbey. The current building dates to 1300 to 1350, when the chapel was rebuilt. It is a rare survival of an independent medieval chapel.
In 1559, the chapel was converted to a school. For some time in the 17th century, a lock-up for unconvicted prisoners was attached to the building and remained in place until at least 1848. In 1873, the building was restored and used as a public hall, before becoming a school once more. More recently it was used as the Wymondham branch library and then the town's arts centre.
Becket's Chapel was added to Historic England's Heritage at Risk Register in 2018. Urgent repairs are needed to the roof, gutters, drainage and masonry. The restoration of the structure and fabric of the building is essential to ensure its survival.
Trudi Hughes, Heritage at Risk Surveyor at Historic England, said: "I'm delighted that, working with Norfolk Historic Buildings Trust and funding partners, we've found a way to save and repair this remarkable medieval chapel using traditional repairs and techniques combined with measures to reduce dampness and improve its carbon footprint.
"This striking building has such a story to tell, having had a fascinating and varied history. It's wonderful that this gem of a building will once again be at the heart of its local community and attracting visitors to this historic market town hopefully for many years to come."
The building will be purchased by Norfolk Historic Buildings Trust (NHBT). Entirely self-financing and largely run by volunteers, the trust conserves and promotes Norfolk's built heritage. It plans to repair and improve the chapel to become a local community hub, run by Wymondham Arts Forum, and to promote Wymondham as a heritage destination for visitors.
Historic England previously contributed grant funding of £51,000 for project development work on the chapel, partnering development grants of £45,000 from the Architectural Heritage Fund.
Funding for the project has also been pledged by the Architectural Heritage Fund, Norwich Freemans Charity, The Pilgrim Trust, The Headley Trust and Geoffrey Watling Charity.
Judith Harwood, Chair of Norfolk Historic Buildings Trust, said: "We are delighted to have secured the funding for the first phase of this exciting project to repair and upgrade Becket's Chapel. This extraordinary chapel, right in the heart of the historic centre of Wymondham, is of significant architectural and historical importance. We are relieved that its future can now be assured for the benefit of the local community through the generous support of our funders.
"This is a ground-breaking project which supports the drive to net zero by incorporating insulation, locally sourced materials where possible and, we hope, in the second phase, powered by renewable energy."

The Hidden Dangers of Shadow Admins
*****By Rich Peckham, Sr. Solution Architect, Silverfort*****
Shadow Admin accounts are user accounts that have sensitive privileges – not because they are members of a privileged Active Directory (AD) group, but because they were inadvertently assigned permissions that can allow them to take over other privileged accounts, and leverage them to reach their target systems to compromise them.
If a Shadow Admin account is compromised, it can be very risky for the organization. After all, these user accounts can be used to compromise additional accounts and gain administrative privileges.
Yet identifying these accounts and restricting their access is not a trivial task.
A Deeper Look at Shadow Admins
A Shadow Admin is a user who is not a member of AD administrative groups like Domain Admins, Enterprise Admins, Schema Admins, Administrators, etc. Yet this user will have rights to some sort of administrative capabilities on an admin account, that enable this user to gain further administrative capabilities.
These administrative capabilities include:
 - Full Control Rights (user or group)
 - Write All Properties (on a group)
 - Reset Password (on a user)
 - All Extended Rights (on a user)
 - Change Permissions (user or group)
 - Write Member (on a group)
 - Write Owner (user or group)
 - The Actual Owner (user or group)
Additionally, any user who can take over and control a Shadow Admin of any level, would also be considered a shadow admin.
Let me explain with an example:
Let's say Bob is a Domain Admin (a member of the Domain Administrators group). This means that Bob has administrative access to Active Directory.
Figure 1: Bob is a member of the Domain Administrators Group
Alice is not a member of the Domain Administrators Group. However, Alice has the ability to reset Bob's password. Therefore, Alice can reset Bob's password, login as Bob and execute tasks that require Domain Admin privileges on his behalf. This makes Alice a "Shadow Admin".
Figure 2: Alice can reset Bob's password which makes her a "Shadow Admin"
Now, let's say Larry can reset Alice's password. This means that Larry can reset Alice's password, login as Alice, change Bob's password, then login as Bob and execute tasks that require Domain Admin privileges. This makes Larry a level 2 shadow admin.
Figure 3: Larry can reset Alice's password, which makes him a "Shadow Admin" as well
And It doesn't end with Larry. Who can reset Larry's password?
The process continues and an organization could, potentially, have many shadow admins.
Why and How Are Shadow Admins Created?
There are a few reasons why shadow admins exist in our networks:
 1. Human Error or Mismanagement of User Rights: Shadow Admins can be created by inexperienced administrators by mistake or because they did not fully understand the implications of direct privilege assignments. Although there are no malicious intents behind such shadow admin accounts, they can still present risk to the environment by allowing users unauthorized access to sensitive assets.
 2. Created for Temporary Use but Never Removed: Although this is considered a bad practice, in some cases IT administrators may grant accounts temporary privileges that turn the users into shadow admins, with the intention to remove these privileges at a later date. While this can solve immediate problems, these privileges are often left in place, leaving these accounts with unsupervised administrative privileges.
 3. Adversaries May Create Shadow Admins for Hiding Activities and Remaining Stealthy: Once admin privileges have been achieved, attackers can create a shadow admin accounts to allow persistence and to conceal their activities. These shadow admin accounts can then be used to hide malicious activities while that attacker remains stealthy.
Regardless of the reason behind their creation, shadow admins pose risk to the organization as they allow unauthorized individuals to perform activities that they shouldn't perform. If an adversary gains control over a shadow admin account, it can be used as an attack vector.
The fact that these accounts are not monitored or supervised means that not only you don't know you should restrict their access (you can't fix problems you don't know about), but it also means that unauthorized access and changes may go undetected. In some cases, such unauthorized access or changes may be detected too late – after sensitive data was leaked or after critical systems were compromised.
How Can I Determine Who My Shadow Admins Are?
Identifying shadow admins is a very challenging and complex problem. You first have to determine who your administrators are, i.e. all the users who belong the AD Groups that provide them administrative privileges. Some AD groups are obvious, like the Domain Admin group. But some groups are less obvious. We've seen that in many organizations, different administrative groups are created to support different business purposes. In some cases, you can even find nested groups. It's important to map out all the members of these groups. As we map out the group memberships, we have to take into consideration not only the user identities that show up in the member list, but also any user's Primary Group ID configurations.
Understanding the members of our administrative groups in AD is an important first step, but it's not enough for identifying all privileged accounts in the domain. This is because they do not include the shadow admins. To detect the shadow admins, you need to analyze the ACL permissions granted to each account.
Think You Can Analyze the ACLs? Think Again
As explained above, to detect shadow admins you need to analyze the ACL permission of each account in AD, to understand if the account has privileges over any administrative groups or individual admin accounts. This, in itself, is a very difficult, if not impossible, task for any human being.
If you are able to perform this analysis – it will provide you the first level of shadow admins.
But it's not enough – you now need to analyze all the ACLs again to understand who has privileges to change these first level shadow admins. And then again, and again, and again – this process needs to continue until all the levels of your shadow admins are detected.
And what if you found a shadow admin group? That complicates things even more.
The bottom line is that this important analysis can't be a manual task.
How Can Silverfort Help?
Silverfort periodically queries Active Directory to get the different ACLs of all the objects in the domain. It automatically identifies common admin groups. It then analyzes the ACLs in search of shadow admin users and groups that have equivalent privileges to the members of these admin groups – privileges that effectively make them shadow admin accounts/groups. It continues to analyze the ACLs to determine as many times as needed to identify all levels of shadow admin accounts and groups making sure you have full visibility into those potentially dangerous accounts.
This comprehensive list should then be reviewed by AD administrators to determine if the privileges or these shadow admin accounts and groups are legitimate or not, and if they should be restricted or supervised.
Figure 4: Silverfort automatically identifies shadow admin accounts that should be reviewed to determine if their privileges are legitimate or not
In addition, Silverfort continuously monitors and analyzes all the access requests across the domain. It considers shadow admins as high-risk accounts. Silverfort automatically identifies, in real-time, sensitive activities, like an attempt to reset a user password, and either alert on it, or require the user the validate his/her identity with multi-factor authentication (MFA) before allowing the password reset. This can prevent unauthorized changes to user accounts as well as any unauthorized access to sensitive assets in the network.

Trade-Off Between Carbon Dioxide Emissions and Logistics Costs Based on Multiobjective Optimization

Route selection, Route choice, Port of Rotterdam, Port of Gdansk, Multiobjective optimization, Mode choice, Modal choice, Logistics, Intermodal transportation, Intermodal systems, Hub and spoke systems, Freight transportation, Decision support systems, Costs, Choice of transportation, Carbon dioxide, Business logistics
This paper examines the relationship between the freight transport costs and the carbon dioxide (CO2) emissions in given intermodal and truck-only freight networks. When the trade-off, which is represented as the relationship, is changed, the freight mode share and route choice are also modified. To show the ever changing trade-off and mode and route choice, a decision-support tool was developed. The given intermodal freight networks represent different freight combinations (i.e., a truck-only system, a rail-based intermodal system, and a short sea-based intermodal system). Because CO2 constraints in logistics markets will need to be realized in the near future, a modal shift in freight transportation could be expected to reduce the CO2 emissions within the reasonable cost and time constraints. The technique of multiobjective optimization is used as the core of the decision-support tool for clarifying the relationship. The tool that was developed is applied to a simplified freight transport network connecting two large European ports: the Port of Rotterdam (the Netherlands) and the Port of Gdansk (Poland). The initial solution, based on the minimization of freight costs, shows that the mode share of freight is local and regional freight transportation situations, whereas the other solutions balanced with CO2 emissions show that the mode share is changed into an intermodal freight system, which is based on a hub-and-spoke network. In considering the changing demands and capacities of freight systems, five scenarios are tested to examine the impact of mode and route change on the trade-off. The results of scenario analyses show that the trade-off is significantly influenced by the demands and capacities of systems.

text: Millimeter wavelength radio telescopes require a high surface and pointing precision, which in steerable open-air telescopes is obtained by a stiff or homologous construction and elaborate thermal control. The perturbing thermal loads and wind loads can also be reduced by protecting the telescope by a radome or astrodome, as applied on several operating telescopes. However, for the new generation telescopes of 30-m to 50-m diameter the radome or astrodome is very large and costly, and it is a priori not certain to which extent the internal thermal climate must be controlled, for instance, by forced air-conditioned ventilation, to obtain a telescope of good radio performance. We present data from the Onsala and Haystack radomes to illustrate agreement between measurements and thermal model calculations, and we use similar calculations to investigate the thermal behavior of a very large astrodome and radome. The accuracy of the calculations is sufficient for design and operational purposes.

Utilizing the Hydravent Ventilation System, the Hydraway 2000 can be installed beneath pond and lagoon liners to act as a vent to protect from damage caused by methane gas and water accumulation.
Often times, pond liners float up off the bottom due to excess water or air buildup beneath the liner. Areas of high organic matter soil tend to give off excess methane gas, whereas others have a high water table and/or large rain events. Both of these cause the liner to float away from the bottom to the surface. previously, the only solution would be to cut and patch the flexible membrane liner (FML).
By installing the Hydravent Ventilation System below the liner, the Hydraway 2000 channels any accumulated water or methane gas away from the liner, ultimately preventing floating liners or ???????whale backs?????.
Vendor Information: The superior product line of the Hydraway Drainage System creates the most effective and state-of-the-art waterproofing and soil water management system available on the market today. Hydraway Drain removes water from soils and relieves the Hydrostatic pressure against subsurface structures. Water from the saturated soil passes through a filter fabric enters the core and is conveyed to an outlet pipe. Hydraway is an engineered alternative to conventional pipe and rock systems.

How To Install Carriage Bolts In 5 Easy Steps
Pulished on Aug. 24, 2021
How To Install Carriage Bolts In 5 Easy Steps
Step 1: Measure the carriage bolts
First, you need to measure the carriage bolt you have chosen.
To do this, find a measurement tap and determine the diameter and length of the bolts you are using.
Step 2: Take the bolt sized drill bit
It is very important to obtain a drill bit the same size as the carriage bolt. If the size does not match, then you may not be able to install the bolts correctly.
If you choose a larger drill bit for drilling, it will cause the bolts to loosen.
And if you choose a smaller one, you can't put the carriage bolts in the holes to fix it. Therefore, determine the exact size of the drill bit in order to drill up this hole.
If you drill holes on a metal surface, you should coat the drill bit with cutting fluid. The coating will help make perforation easier.
Step 3: Use a drill machine to dig a hole
Next, you need to dig a hole in the material where you want to install the carriage bolts. In addition, slowing down the drilling speed can help you control the drilling speed.
Step 4: Use a hammer to insert the bolt into the hole
You can slide the carriage bolt into the hole you drilled. The hole you drilled maybe a bit clogged.
So, in order to avoid the problem of bolts sliding into the holes, you can use a hammer to drive the bolts in.
Tap the bolt lightly with a hammer, and the rest of the work is done.
Step 5: Put in the washer and tighten up the bolt
After placing the bolts in the holes, it is now time to complete the installation of the carriage bolts.
A washer needs to be placed on the reverse side of the bolt and material. Bolt domes and washers must be placed on different sides of the material.
When you have successfully installed the washer, it is time to put the nut on it. Roll over a nut on the bolt and tighten it with a wrench.
The square shoulder on the bolt prevents rotation on the material.
The shoulder helps to keep the carriage bolt firmly on the element and form a strong bond.
The installation guide needs to follow accurately in order to install the carriage bolts on any surface and make the bonding between different parts of the element stronger.
In addition, the placement of carriage bolts should be determined before drilling.
In this way, you can guarantee perfect holes and also make perfect connections between wood or metal parts.

How to use carriage bolts?
It is very common to use carriage bolts when making different types of furniture or machines. These bolts need to be perfectly placed and installed to work properly.
Therefore, the use of bolts is more likely to make the process tighter and bring things together in a stronger way.
Therefore, the use of bolts should be predetermined, if you need it or not.
