There are a number of security protocols in place to prevent unauthorised access to PDF documents. Before using the PDF shortcode or merge tag it's highly recommended you review the documentation detailing PDF security so that your users don't get an access denied error when attempting to view or download the PDFs.
For the best balance between security and access, it is recommended to enable signed PDF URLs so that anyone with access to the link can view the document for a specific time period (which you define).
They are special auto-expiring URLs that allow anyone with the link to view the PDF. They are useful if you want to share the URL via email to a third party, don't want to store IP addresses with entries, or would like to display the link on a page restricted to specific user role(s). Both Shortcode and Merge Tag options support signed URLs, but the feature has to be enabled (see below). Find out more about the PDF security and how Signed PDF URLs fit in the picture.
We recommend using the Shortcode method when possible because it not only generates the correct URL to the PDF, but it automatically wraps it up in an anchor tag so that it becomes a clickable link. The merge tag has its uses though, especially when you want to include the PDF URL in a HTML attribute (WordPress' security doesn't allow shortcodes to be processed when in HTML attributes).
You can easily add a PDF download link to Gravity Forms Confirmations and/or Notifications with the [gravitypdf] shortcode. Using the optional Entry Attribute you can include the shortcode on any WordPress page (good for Page Confirmations). If you only need the raw PDF URL, you can add the raw shortcode attribute or use the PDF Merge Tag instead.
A Download Shortcode column can be found on the PDF form list page, which includes each PDF's shortcode. Just copy and paste the shortcode sample to your confirmation or notification and click save. The default behaviour is to generate a download link to the PDF with the text Download PDF. Simple!
The text confirmation is the simplest Gravity Forms confirmation type and allows you to add a message using the WordPress classic editor, which is then shown to the user right after submission. Copy and paste the Gravity PDF shortcode found on the PDF form list and save the confirmation.
The page confirmation allows you to redirect users to an existing WordPress page. First, copy the Gravity PDF shortcode found on the PDF form list and place it on the WordPress page you're sending the users to. Once done, go back to your page confirmation configuration and enable the Pass Field Data Via Query String option. Add entry=entry_id to the field that appears and click save.
For security reasons the Signed PDF URL feature is disabled for this confirmation type (as of v6.9.1). Signed URLs can be used with Text or Redirect Confirmation types, in Notifications, or when the entry ID is passed as a shortcode attribute.
The redirect confirmation allows you to send the user to another location upon completing their form. If you choose, you can redirect the user straight to a PDF. To get it functioning you need to copy and paste the Gravity PDF shortcode found on the PDF form list and then save.
Gravity Forms Notifications are automated emails sent after the form is submitted. If you would prefer not sending the PDF as an email attachment (usually for security reasons), you can use the [gravitypdf] shortcode to include a link to the PDF. Because of the default security protocols, this method is very effective when the recipient has a WordPress user account. If users aren't logged in when completing the form, or you want to email a link to the document to a third party, use the signed PDF URL feature.
While we provide a quick and easy way to get a particular PDF's [gravitypdf] shortcode, it's also useful to know what each attribute does, and how it affects the display of the PDF download link that gets generated.
If the [gravitypdf] shortcode doesn't display a link to the PDF, an error likely occurred. To verify this, enable Debug Mode in the Global PDF Settings and test again using an Administrator WordPress account. An error message will be displayed on the screen where the shortcode has been rendered and provide more information about why nothing was displayed.
Gravity Forms merge tags are placeholders that are replaced with dynamic information in notification emails, confirmation pages, PDFs, and more. Take a look at the Gravity Forms documentation to get a better understanding of them.
When you've PDFs configured on a form, Gravity PDF merge tags are automatically included in the merge tag selector on the form settings pages. The merge tag selector is a button denoted by ... When selected, a list will be displayed with merge tags you can insert into the current setting. You'll find the available PDFs listed under the Custom heading at the bottom and prefixed with the text "PDF:".
Unlike the shortcode, the merge tags are converted to a URL only (akin to using the raw shortcode attribute). The benefit over shortcodes is they can be placed inside HTML attributes ..., and can be used anywhere Gravity Forms supports merge tags in general.
If a URL isn't displayed when the PDF merge tag is processed it's likely the PDF doesn't exist for the current form, it has been deactivated, or the conditional logic doesn't pass. To determine the exact reason it wasn't generated, enable Gravity Forms logging and then replicate the issue. In the Gravity PDF log file search for PDF Merge tag is not valid and review the logged information.
In the sample log, the merge tag wasn't displayed because the PDF cannot be found in the current form (denoted by the error message). Verify the PDF exists from the form PDF list page. Then use the merge tag selector to update the merge tag.
In the sample log, the merge tag wasn't displayed because the current entry being processed did not pass the PDF's conditional logic (denoted by the error message). Provided your conditional logic is correct, this may not be a problem at all. Double check the PDF Conditional Logic setting.
This collection contains gravity gradient and gravity anomalies grids at ground level and at satellite height. In addition it contains the GOCE gravity field models (EGM_GOC_2, EGM_GCF_2) and their covariance matrices (EGM_GVC_2):
As output from the ESA-funded GOCE+ GeoExplore project, GOCE gravity gradients were combined with heterogeneous other satellite gravity information to derive a combined set of gravity gradients complementing (near)-surface data sets spanning all together scales from global down to 5 km. The data is useful for various geophysical applications and demonstrate their utility to complement additional data sources (e.g., magnetic, seismic) to enhance geophysical modelling and exploration.
The GOCE+ GeoExplore project is funded by ESA through the Support To Science Element (STSE) and was undertaken as a collaboration of the Deutsches Geodtisches Forschungsinstitut (DGFI), Munich, DE, the Christian-Albrechts-Universitt zu Kiel, the Geological Survey of Norway (NGU), Trondheim, Norway, TNO, the Netherlands and the University of West Bohemia, Plzen, CZ.
Crazy Gravity is a great rocket-flying game similar to Gravity Force for the Commodore 64. The goal is simple: fly through a system of caverns with your silver spaceship, take freight on board, and carry these freight containers to your homebase. Along the way, you must get past many obstacles. Fans blow your ship against rocks, magnets attract you, rods move into your way and cannons bombard you with fireballs.
Since you must constantly struggle against the force of gravity, your task is even more difficult. Inertia is simulated well in the game, and piloting the ship requires finely-honed reflexes. Each new level brings new obstacles and barriers, always in new formations; some even include physical puzzles that you must figure out how to get through -- particularly how to get to the freight. You must also watch the fuel level: accelerate too often, and you may run out of fuel.
We may have multiple downloads for few games when different versions are available.Also, we try to upload manuals and extra documentation when possible. If you have additional files to contribute or have the game in another language, please contact us!
The payload container includes four heated surfaces, each with a different surface treatment, submerged in a specialized fluid that boils at the relatively low temperature of 135 degrees Fahrenheit. The experiments will demonstrate whether engineered surfaces could improve boiling and bubble detachment in reduced gravity.
In April, SwRI research engineers Dr. Eugene Hoffman, Dr. Akbar Whizin, and Emilio Gordon accompanied the experiment on a parabolic flight campaign from Ft. Lauderdale aboard a reduced gravity aircraft. They gathered data and observations during two flights at multiple gravity levels.
Land and marine gravity surveys, grids, models, and geoids are listed below. Data parameters include latitude, longitude, observed gravity and elevation, Bouguer Gravity Anomaly (land), and Free-air Anomaly (ocean). Each dataset contains documentation, including source contributor.
Approximately 70 percent of the data are observed values--regional station data collections (separated primarily by contributors) and absolute gravity measurements. Grids and other derived summary data sets represent another 30 percent of the data.
A standard format description for the land gravity data preserves fields unique to a specific data collection. Marine gravity data are stored in the MGD77 format. Standard terminology, as well as minimum / maximum values and histogram distributions for each parameter are available. Point distribution plots are .PCX and .GIF images.
Gravity anomaly data show variations in the gravity field caused by lateral variations in the density of the Earth's crust and upper mantle that reflect variations in composition and thickness. Systematic gravity mapping began in Canada in 1944 and is ongoing. All data are tied to the International Gravity Standardization Network 1971. Local gravity anomalies result from the juxtaposition of relatively high- and low-density rock types. Longer wavelength anomalies such as the gravity low over the Cordillera and the relative gravity high over oceanic crust largely reflect variations in the thickness of the crust.
