In mathematics , physics and chemistry , a space group is the symmetry group of a configuration in space, usually in three dimensions. Space groups are also studied in dimensions other than 3 where they are sometimes called Bieberbach groups , and are discrete cocompact groups of isometries of an oriented Euclidean space. In crystallography , space groups are also called the crystallographic or Fedorov groups , and represent a description of the symmetry of the crystal. A definitive source regarding 3-dimensional space groups is the International Tables for Crystallography Hahn Space groups in 2 dimensions are the 17 wallpaper groups which have been known for several centuries, though the proof that the list was complete was only given in , after the much more difficult classification of space groups had largely been completed. The space groups in three dimensions are made from combinations of the 32 crystallographic point groups with the 14 Bravais lattices , each of the latter belonging to one of 7 lattice systems.

Internal and external rotation exercises of the shoulder are frequently performed to avoid injury and pain. Knowledge about the motion and loadings of the upper extremities during these exercises is crucial for the development of optimal training recommendations. However, a comparison of the angles and corresponding moments in the upper extremities that are achieved during internal and external rotation exercises for the shoulder by using different resistance types has not yet been performed.

Violence against health workers is already endemic and growing rapidly. The BPG provides 15 evidence-based recommendations for health service organizations and academic institutions so they can recognize, prevent and manage violence, harassment and bullying in the workplace, changes that will enable nurses and other health professionals to focus even more care on patients. Recommendations focus on: 1 risk assessment tools and strategies; 2 organizational policies, procedures, and responsibilities; and 3 educational approaches and strategies. The second edition of this guideline builds upon the most recent and relevant evidence to improve earlier guidelines issued in and Working through the recommendations in the guideline will give organizations the confidence that they are taking critical steps to protect healthcare workers and provide quality care to their patients.

Chromatography, specifically liquid chromatography, is used extensively in pharmaceutical development and manufacturing. In the pharmaceutical industry, countless HPLCs are working in research and quality control laboratories, churning out innumerable test results each day on the dosage levels, purity, and dissolution characteristics of new drug candidates or marketed products. In other words, how can researchers be assured that each HPLC system is functioning properly on any particular day. These are not academic questions, given the serious role of the pharmaceutical business in developing safe and efficacious drugs for human consumption.
