Product Description. Philips norelco sensotouch 3d rq12 shaving replacement head. For maximum shaving performance, it is recommended to replace your shaving unit once every 12 months. The unique ultratrack heads combine channels to catch the longer hairs, slots to catch the normal hairs, and holes to catch the shortest stubble. These heads catch every hair with fewer strokes.

cdem is a macOS application for discrete element modeling of geological structures and their associated deformation in 2D. cdem integrates pre-processing, processing, and post-processing (visualization) in a single application.
Different assemblies, properties, and boundary conditions can be chosen. The progress of the simulation can be observed in real time. When the run is complete, geometry, displacement, or strain can be visualized, or saved as an image or a movie. cdem is a document-based application, multiple simulations can be run at the same time. cdem is a great, simple and elegant tool for teaching and research.
cdem runs on macOS 10.14 (Mojave) and above. cdem is a shareware program.

Stereonet3D can perform various operations, including calculating poles to planes, rotating planes and lines, constraining lines to lie on their planes, angle between lines or planes, cylindrical best fit, conical best fit, and mean vector. Data with lat-long information can be exported to Google Earth.
More information about Stereonet3D can be found in Cardozo and Allmendinger (2013). Stereonet3D runs on Mac OSX 10.9 or later. It is freely available on the Mac App Store.
To test the program's Map view and export to kml, here are two files with strike/dip data from the Big Elk anticline in SE Idaho, and locations in lat-long or UTM (right click to download and open with the program's File -> Load Dataset from txt menu).
GeoKalk is a document based application. Multiple calculators can be opened and saved as independent documents. Multiple entries can be operated using tables. Entries can be load from and written to text files. Lines and planes can be visualized in a stereonet, and strain and stress in a Mohr circle. In 3D stress, the stereonet and Mohr circle can be coloured by slip tendency. Besides being a great tool to learn vectors and tensors and their application to geology and engineering, GeoKalk is a powerful tool to perform operations on thousands of vectors or tensors.
GeoKalk was made for geologists, but it can be used by anyone interested in vectors and tensors. GeoKalk runs on Mac OSX 10.9 or later. It is freely available on the Mac App Store.
SSPX can process single files, or batch process sequential files. Data with lat-long information (e.g. GPS stations) can be plotted on a Map/Satellite view. SSPX was made for geologists, but it can be used by anyone interested in computing strain/strain rate from displacement/velocity data.
More information about SSPX can be found in Cardozo and Allmendinger (2009). SSPX runs on Mac OSX 10.9 or later. It is freely available on the Mac App Store.
Here you can find some GPS and DEM files to test the program.
Geometry and strain data can be visualized in a 3D plot which can be sliced along any orientation and queried for strain. Geometry and strain are also displayed in tables which can be exported. Trishear3D is a great tool to investigate the impact of temporal and spatial variations of fault parameters on the 3D geometry and strain field of fault related folds.
Trishear3D runs on Mac OSX 10.9 or later. The program is free for non-profit purposes (for consulting please contact me).

The subsidence of a sedimentary basin is due to: tectonic subsidence, water and sediment loading, and sediment compaction. These three components can be estimated from a stratigraphic section using 'backstripping' (Allen and Allen, 1990). This removes from each sedimentary layer the effects of sediment compaction and water and sediment loading; thus extracting from the section the tectonic subsidence curve.Backstrip (previously OSXBackstrip) is a program to perform '1D Airy backstripping with exponential porosity reduction'. Stratigraphic units can be input in a table, and backstripping and tectonic subsidence plots and tables can be produced. Plots can be edited or saved for publication. Multiple documents (stratigraphic sections) can be backstripped and compared.
Backstrip runs on Mac OSX 10.9 or later. The program is free for non-profit purposes (for consulting please contact me).

The displacement profile of the surface of the earth under crustal loads (e.g. mountain chains) can be well reproduced by an elastic flexural model. In this model, the uppermost layer of the earth responds to crustal loads as an elastic beam floating in a weaker, fluid-like foundation (i.e. the astenospheric mantle, Turcotte and Schubert, 1982).Flex2D (previously OSXFlex2D) implements the elastic flexural model in 2D for a plate of constant or variable elastic thickness. Crustal loads can be entered and plotted, and the profile of deformation produced by these loads can be computed and visualized in plots and tables. Plots can be edited or saved for publications. Multiple load profiles can be computed and compared.
Flex2D runs on Mac OSX 10.9 or later. The program is free for non-profit purposes (for consulting please contact me).

Schedule of Classes
Please note that due to COVID-19, we have limited in person course offerings to only those courses our clients deem essential, such as lifesaving skills courses including ACLS, BLS, NRP and PALS. When possible, we have moved courses online, in an instructor led interactive format, via Zoom. We are honored to continue providing education to healthcare workers and first responders during this crisis.
