The purpose of a Safety Data Sheet (SDS), formerly known as Material Safety Data Sheets (MSDS), is to provide information on the hazards of working with a chemical and procedures that should be used to ensure safety. State and Federal law require that employers obtain an SDS for each hazardous substance they use or store and make the SDS available to employees. The PI/instructor is responsible ...

The connection between a surface's metric and its Gaussian curvature (Gauss theorem) provides the base for a shaping principle of locally growing or shrinking elastic sheets. We constructed thin gel sheets that undergo laterally nonuniform shrinkage. This differential shrinkage prescribes non-Euclidean metrics on the sheets. To minimize their elastic energy, the free sheets form three-dimension...

Nanostructural Al 1050 sheets were produced using a novel method of asymmetric cryorolling under ratios of upper and down rolling velocities (RUDV) of 1.1, 1.2, 1.3, and 1.4. Sheets were rolled to about 0.17 mm from 1.5 mm. Both the strength and ductility of Al 1050 sheets increase with RUDVs. Tensile strength of Al sheets with the RUDV 1.4 is larger 22.3% of that for RUDV 1.1, which is 196 MPa...

BACKGROUND There is considerable interest in using cell sheets for the treatment of various lesions as part of regenerative medicine therapy. Cell sheets can be prepared in temperature-responsive culture dishes and applied to injured tissue. For example, cartilage-derived cell sheets are currently under preclinical testing for use in treatment of knee cartilage injuries. The additional use of c...

We introduce a toy model of crumpled sheets, and use Monte Carlo simulation to show there is a first-order phase transition in the model, from a disordered dilute phase to a mixture with a layered phase. We demonstrate the transition through two order parameters, corr and lay, the first of which measures orientational order while the second measures bulk layering. An important feature of the ar...

Some facts about 4-spinors listed and discussed. None, well perhaps some, of the work is original. However, locating formulas in other places has proved a timeconsuming process in which one must always worry that the formulas found in any given source assume the other metric ( I use {−1,−1,−1,+1}) or assume some other unexpected preconditions. Here I list some formulas valid in general represen...

toichiometric analysis has the same function in biochemistry as book-keeping has in business. Both deal with the inputs and outputs in flow systems, and studying the stoichiometric structure of a metabolic network might seem only slightly more exciting than a visit to an accountant's office. Times change, however, and progress in systems biology will involve paying closer attention to stoichiom...
