The terminal velocity of cloud and precipitation size drops has been analyzed for three physically distinct flow regimes: 1) slip flow about a water drop treated as rigid sphere at negligible Reynolds numbers, 2) continuum flow past a water drop treated as a rigid sphere with a steady wake at low and intermediate Reynolds numbers, and 3) continuum flow around a non-circulating water drop of equilibrium shape with an unsteady wake at moderate to large Reynolds numbers. In the lower regime the effect of slip was given by the first-order Knudsen number correction to Stokes drag. In the middle regime a semiempirical drag relation for a rigid sphere was used to obtain a formula for the Reynolds number in terms of the Davies number. In the upper regime a correlation of wind tunnel measurements on falling drops was used in conjunction with sea level terminal velocities for raindrops to obtain a formula for the Reynolds number in terms of the Bond number and physical property number.
In the example above, the variable is $a and the value is Velocity. This variable, like all references, begins with the $ character. String values are always enclosed in quotes, either single or double quotes. Single quotes will ensure that the quoted value will be assigned to the reference as is. Double quotes allow you to use velocity references and directives to interpolate, such as \"Hello $name\", where the $name will be replaced by the current value before that string literal is assigned to the left hand side of the =
Velocity 1.6 introduces the concept of strict reference mode which is activated by setting the velocity configuration property 'runtime.references.strict' to true. The general intent of this setting is to make Velocity behave more strictly in cases that are undefined or ambiguous, similar to a programming language, which may be more appropriate for some uses of Velocity. In such undefined or ambiguous cases Velocity will throw an exception. The following discussion outlines the cases in which strict behavior is different from traditional behavior.
By default, this feature of using single quotes to render unparsed text is available in Velocity. This default can be changed by editing velocity.properties such that stringliterals.interpolate=false.
It's possible to set a maximum allowed number of times that a loop may be executed. By default there is no max (indicated by a value of 0 or less), but this can be set to an arbitrary number in the velocity.properties file. This is useful as a fail-safe.
The #include script element allows the template designer to import a local file, which is then inserted into the location where the #include directive is defined. The contents of the file are not rendered through the template engine. For security reasons, the file to be included may only be under TEMPLATE_ROOT.
The file being included need not be referenced by name; in fact, it is often preferable to use a variable instead of a filename. This could be useful for targeting output according to criteria determined when the page request is submitted. Here is an example showing both a filename and a variable.
VTL templates can have #parse statements referring to templates that in turn have #parse statements. By default set to 10, the directive.parse.max.depth line of the velocity.properties allows users to customize maximum number of #parse referrals that can occur from a single template. (Note: If the directive.parse.max.depth property is absent from the velocity.properties file, Velocity will set this default to 10.) Recursion is permitted, for example, if the template dofoo.vm contains the following lines:
The #break directive stops any further rendering of the current execution scope. An \"execution scope\" is essentially any directive with content (i.e. #foreach, #parse, #evaluate, #define, #macro, or #@somebodymacro) or any \"root\" scope (i.e. template.merge(...), Velocity.evaluate(...) or velocityEngine.evaluate(...)). Unlike #stop, #break will only stop the innermost, immediate scope, not all of them.
The #stop directive stops any further rendering and execution of the template. This is true even when the directive is nested within another template accessed through #parse or located in a velocity macro. The resulting merged output will contain all the content up to the point the #stop directive was encountered. This is handy as an early exit from a template. For debugging purposes, you may provide a message argument (e.g. #stop('$foo was not in context') ) that will be written to the logs (DEBUG level, of course) upon completion of the stop command.
velocimacro.library.autoreload - This property controls Velocimacro library autoloading. The default value is false. When set to true the source Velocimacro library for an invoked Velocimacro will be checked for changes, and reloaded if necessary. This allows you to change and test Velocimacro libraries without having to restart your application or servlet container, just like you can with regular templates. This mode only works when caching is off in the resource loaders (e.g. file.resource.loader.cache = false ). This feature is intended for development, not for production.
(where is the name of the resource loader that you are using, such as 'file') then the Velocity engine will automatically reload changes to your Velocimacro library files when you make them, so you do not have to dump the servlet engine (or application) or do other tricks to have your Velocimacros reloaded.

CW Doppler is sensitive, but, because it measures velocity along the entire length of the ultrasound beam and not at a specific depth, it does not localize velocity measurements of blood flow. It is used to estimate the severity of valve stenosis or regurgitation by assessing the shape or density of the output (see Figure 3).
PW Doppler was developed because of the need to make localized velocity measurements of turbulent flow (it measures the blood-flow velocity within a small area at a specified tissue depth). It is used to assess ventricular in-flow patterns, intracardiac shunts, and to make precise measurements of blood flow at valve orifices.
CFM uses measurements of the velocity and direction of blood flow to superimpose a color pattern onto a section of a 2D image (see Figure 4). Traditionally, flow towards the transducer is red, flow away from the transducer is blue, and higher velocities are shown in lighter shades. To aid observation of turbulent flow there is a threshold velocity, above which the color changes (in some systems to green). This leads to a \"mosaic\" pattern at the site of turbulent flow and enables sensitive screening for regurgitant flow.
When flow across the MV is assessed with PW Doppler, two waves are characteristically seen. These represent passive filling of the ventricle (early [E] wave) and active filling with atrial systole (atrial [A] wave). Classically, the E-wave velocity is slightly greater than that of the A wave (see Figure 5). However, in conditions that limit the compliance of the LV, two abnormalities are possible:
The etiology of aortic stenosis (AS) can be confirmed by the visualization of either a bicuspid valve or calcification. The severity of the stenosis can be estimated by measuring high-velocity flow across the valve by Doppler. This can be converted to an estimation of the pressure drop. In addition, the effective orifice area can be measured (see Table 2).
With mitral stenosis (MS), as with AS, calcified, immobile MV leaflets can be demonstrated with 2D and M-mode echo. Anterior motion of the posterior MV leaflet in diastole (caused by commissural fusion) is characteristic in MS. Doppler demonstrates increased flow velocity and can be used to estimate the effective orifice area (see Table 3).
You need to specify ID fields with certain API method calls. There are threetypes of IDs used within Google Books: Volume IDs - Unique strings given to each volume that Google Books knows about. An example of a volume ID is _LettPDhwR0C. You can use the API to get the volume ID by making a request that returns a Volume resource; you can find the volume ID in its id field. Bookshelf IDs - Numeric values given to a bookshelf in a user's library. Google provides some pre-defined shelves for every user with the following IDs: Favorites: 0 Purchased: 1 To Read: 2 Reading Now: 3 Have Read: 4 Reviewed: 5 Recently Viewed: 6 My eBooks: 7 Books For You: 8 If we have no recommendations for the user, this shelf does not exist. Custom shelves have IDs greater than 1000. A bookshelf ID is unique for a given user, i.e., two users can have a bookshelf with the same ID that refer to different bookshelves. You can use the API to get the bookshelf ID by making a request that returns a Bookshelf resource; you can find the bookshelf ID in its id field. User IDs - Unique numeric values assigned to each user. These values are not necessarily the same ID value used in other Google services. Currently, the only way retrieve the user ID is to extract it from the selfLink in a Bookshelf resource retrieved with an authenticated request. Users can also obtain their own user ID from the Books site. A user cannot obtain the user ID for another user via the API or the Books site; the other user would have to share that information explicitly, by email for example. 153554b96e
