UML activity diagram - Servlet container

"Web container (also known as a Servlet container) is the component of a web server that interacts with Java servlets. A web container is responsible for managing the lifecycle of servlets, mapping a URL to a particular servlet and ensuring that the URL requester has the correct access rights. A web container implements the web component contract of the Java EE architecture, specifying a runtime environment for web components that includes security, concurrency, lifecycle management, transaction, deployment, and other services. A web container provides the same services as a JSP container as well as a federated view of the Java EE platform APIs." [Web container. Wikipedia]
The UML activity diagram example "Servlet container" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.

"Merox is an acronym for mercaptan oxidation. It is a proprietary catalytic chemical process developed by UOP used in oil refineries and natural gas processing plants to remove mercaptans from LPG, propane, butanes, light naphthas, kerosene and jet fuel by converting them to liquid hydrocarbon disulfides.
The Merox process requires an alkaline environment which, in some of the process versions, is provided by an aqueous solution of sodium hydroxide (NaOH), a strong base, commonly referred to as caustic. In other versions of the process, the alkalinity is provided by ammonia, which is a weak base.
The catalyst in some versions of the process is a water-soluble liquid. In other versions, the catalyst is impregnated onto charcoal granules.
Processes within oil refineries or natural gas processing plants that remove mercaptans and/ or hydrogen sulfide (H2S) are commonly referred to as sweetening processes because they results in products which no longer have the sour, foul odors of mercaptans and hydrogen sulfide. The liquid hydrocarbon disulfides may remain in the sweetened products, they may be used as part of the refinery or natural gas processing plant fuel, or they may be processed further.
The Merox process is usually more economical than using a catalytic hydrodesulfurization process for much the same purpose." [en.wikipedia.org/ wiki/ Merox]

The vector stencils library "Progressive disclosure controls" contains 12 icons of Windows 8 progressive disclosure controls.
Use it to design graphic user interface (GUI) prototypes of your software applications for Windows 8.
"With a progressive disclosure control, users can show or hide additional information including data, options, or commands. Progressive disclosure promotes simplicity by focusing on the essential, yet revealing additional detail as needed. ...
Chevrons show or hide the remaining items in completely or partially hidden content. Usually the items are shown in place, but they can also be shown in a pop-up menu. When in place, the item stays expanded until the user collapses it. ...
Arrows show a pop-up command menu. The item stays expanded until the user makes a selection or clicks anywhere.
If the arrow button is an independent control, it receives input focus and is activated with the space bar. If the arrow button has a parent control, the parent receives input focus and the arrow is activated with Alt+down arrow and Alt+up arrow keys, as with the drop-down list control. ...
Plus and minus controls expand or collapse to show container content in place when navigating through a hierarchy. The item stays expanded until the user collapses it. Although these look like buttons, their behavior is in-place.
The associated object receives input focus. The plus is activated with the right arrow key, and the minus with the left arrow key. ...
Rotating triangles show or hide additional information in place for an individual item. They are also used to expand containers. The item stays expanded until the user collapses it.
The associated object receives input focus. The collapsed (right-pointing) triangle is activated with the right arrow key, and the expanded (downward-pointing) triangle with the left arrow key. ...
Like chevrons, additional information is shown or hidden in place. The item stays expanded until the user collapses it. Unlike chevrons, the glyphs have a graphical representation of the action, typically with an arrow indicating what will happen. ... Preview arrows are best reserved for situations where a standard chevron doesn't adequately communicate the control's behavior, such as when the disclosure is complex or there is more than one type of disclosure."

The vector stencils library "Watercraft" contains 28 clip art images for creating ship transport illustrations, presentation slides, infographics and webpages using the ConceptDraw PRO diagramming and vector drawing software.
"The term watercraft covers a range of different vehicles including ships, boats, hovercraft and submarines, and differs from a simple device that merely floats, such as a log raft. ...
Usually the purposes behind watercraft designs and skills are for seafaring education or leisure activities, fishing and resource extraction, transportation of cargo or passengers, and for conducting combat or salvage operations. In general, the purpose of a water vehicle identifies its utility with a maritime industry sub-sector." [Watercraft. Wikipedia]

The vector stencils library "GHS hazard pictograms" contains 9 chemical hazard symbols.
Use it in ConceptDraw PRO software to design your chemical safety infographics, labels of containers with hazardous materials, International Chemical Safety Cards (ICSC), manufacturers' Safety Data Sheets (SDS), and Material Safety Data Sheets (MSDS).
"Hazard pictograms form part of the international Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Two sets of pictograms are included within the GHS: one for the labelling of containers and for workplace hazard warnings, and a second for use during the transport of dangerous goods. ...
Hazard pictograms are one of the key elements for the labelling of containers under the GHS, along with:
- an identification of the product;
- a signal word – either Danger or Warning – where necessary;
- hazard statements, indicating the nature and degree of the risks posed by the product;
- precautionary statements, indicating how the product should be handled to minimize risks to the user (as well as to other people and the general environment);
- the identity of the supplier (who might be a manufacturer or importer)." [GHS hazard pictograms. Wikipedia]

"Heavy equipment refers to heavy-duty vehicles, specially designed for executing construction tasks, most frequently ones involving earthwork operations. They are also known as, heavy machines, heavy trucks, construction equipment, engineering equipment, heavy vehicles, or heavy hydraulics." [Heavy equipment.
