"Fishing Knots" - is a program for your mobile device, showing how to tie knots. Among the many knots fisherman should select and use the right one. In each case - his own. How the knot weakens the fishing line? Which knots to use for thin fishing lines, and which - for thick? Which knots can be knit on multifilament fishing line? The encyclopedia contains different type of knots for: binding of two fishing lines; tying leads; attach large and small hooks, baits, lures, swivels; connection fishing lines and the binding cord; tie a boat and etc.; For each knot, tying methods is described in detail. Also, description of each knot contains step-by-step guide ""How to tie"" with illustrations. Describes in detail the properties of knots. The estimation of the strength reduction for each knot. For each knot provides recommendations for types of fishing lines. The application can also work without the Internet, all the nodes are loaded during installation. Selected knots are simple and clear three-dimensional scheme - this is the app "Fishing knots". Here are a few reasons to install into your device "Fishing Knots": - The maximum number of knotes used by fishermen; - Graphics extensively tested for intelligibility; - The application can run without an Internet connection; - Easy to use interface - this is not a website page with a bunch of useless information at the edges; - Knots are clearly defined by categories; - Each record contain relative knot strength - the breaking strength of a knotted rope in proportion to the breaking strength of the rope without the knot; - It is always being updated, refined and increasing.

XraySource is your convenient reference tool for x-ray physics applications. With features that are useful for beginners, experienced x-ray users, and everyone in between, XraySource makes it easy to find crucial information, allowing you to focus on your research. The app gives you access to data tables, calculators, and other practical physics tools to enhance your x-ray productivity. Whether you are working on x-ray diffraction, x-ray fluorescence, or radiography, this handy app will become a valuable tool for your work. Plus, get the latest x-ray physics news sent right to your phone. Features: - Periodic table of elements, with easily accessible characteristic line data for each element, as well as other physical properties with thanks to the developers of Mendeleev - Absorption tables: Mass-attenuation coefficients by element, as a function of photon energy as reported in the X-ray Data Booklet of the Lawrence Berkeley National Laboratory - Radiation dose converter: Convenient conversion calculator for different units of radiation exposure, radiation doses - Table of physical constants: A handy lookup table for many commonly used constants, as reported by CODATA - An energy-wavelength converter, to easily convert photon wavelengths (both Angstroms and nanometers) into their corresponding energies and vice versa - An absorption calculator, which determines the amount of intensity attenuation to expect from a material with some known thickness or, conversely, how much material is needed to achieve a particular amount of attenuation. In addition, mass-attenuation coefficients can easily be imported from the relevant absorption tables. - A separate characteristic line lookup table, which allows the user to easily filter the entries by energy. Especially useful for XRF applications. - Table of commonly used x-ray tube wavelengths We welcome feedback! If you enjoy this app, please consider leaving a review and rating! This helps others more easily find the app. If you would like a new table, converter, or feature to be added, we'd be delighted to hear from you.
