IrriPro is the only tool that optimizes the use of water and improves the uniformity of distribution, increasing the efficiency of the system and ensuring the proper distribution of water and fertilizers. It also reduces the costs of realization of a...

BRL-CAD is a constructive solid geometry solid modeling system with over 20 years development and producation use by the U.S. military. BRL-CAD includes an interactive geometry editor, parallel ray tracing support for rendering and geometric analysis,...

SCARM is freeware program for simplified design of scaled railway model layouts and modeling of miniature model track routes. It has lightweight and intuitive user interface, 3D view and many other cool functions and features.What is new in this...

Zref allows you to perform two types of calculations from single-crystal diffraction measurements, in order to determine unit-cell parameters. If you have centred reflections in 8 positions on the diffractometer with the zref command in the Single...

DAC_restrict enables you to determine in advance which single-crystal reflections will be accessible from your crystal once it is loaded in to your diamond-anvil cell (DAC), in any specific orientation that you choose. Thus, you can use the program to...

With Twin Calculator, determine the relative orientation of crystals whose orientation matrices have been determined at the same time by single-crystal diffraction. This will work not only for twins but also for any pair of crystals that are in the same...

Conlev is a small utility to calculate the points on a variance-covariance ellipse, specifically written for plotting the covariance of bulk modulus K, and its pressure derivative K'. Before running the program, you need to know the values of K and K'...

Cif Reader is a software tool designed to handle CIFs from parametric refinements, with many data blocks in a single CIF describing the same structure but at a series of temperatures and pressures. The object of the software is two-fold first to provide a...

ABSORB is a program for Windows to correct X-ray intensity data from any source and any detector type (lab or synchrotron, point detector or area detector). Corrections can be made for spherical crystals, and crystals with regular or irregular shapes, and...

Win-IntegrStp is a graphics-based program for Windows to integrate step-scan data from single-crystal diffractometers. It allows the user to examine individual reflections, determine optimum profile parameters and to integrate data-sets automatically or...
