Oligo‐Urea with No Alkylene Unit Self‐Assembles into Rod‐Like Objects in Water

Orientation control of rodlike objects by flow

Suspensions of rodlike objects in a liquid are encountered in many areas of science and technology and the need to orientate them is extremely important to enhance or inhibit certain chemical reactions between them, other chemicals or with the walls of vessels holding the flowing suspension. Orientation control is feasible by altering velocity and nature of the liquid, its flow and the geometry...

Endo-Testing: Unit Testing with Mock Objects

Unit testing is a fundamental practice in Extreme Programming, but most non-trivial code is difficult to test in isolation. It is hard to avoid writing test suites that are complex, incomplete, and difficult to maintain and interpret. Using Mock Objects for unit testing improves both domain code and test suites. They allow unit tests to be written for everything, simplify test structure, and av...

Unit Testing with Déjà-Vu Objects

In this paper we introduce a new unit test technique called déjà-vu object. Déjà-vu objects replace real objects used by classes under test, allowing the execution of isolated unit tests. A déjà-vu object is able to observe and record the behaviour of a real object during real sessions, and to replace it during unit tests, returning previously recorded results. Consequently déjà-vu object techn...

Synthesis and conformational study of water-soluble, rigid, rodlike oligopiperidines.

General Methods. All chemicals were purchased from Aldrich (St. Louis, MO). Fmoc-4-piperidone was supplied by NeoMPS (Strasbourg, France). Analytical HPLC was run on a Varian instrument with a C18 column 5 m (4.6 × 250 mm) from Vydac using a linear gradient of water with 0.1 % TFA (A) followed by acetonitrile containing 0.08 % TFA (B), at a flow rate of 1.2 mL/min (UV detection at 214 and 254 ...
