Delft University of Technology ft]), also known as TU Delft, is the largest and oldest Dutch public technical university, located in Delft, Netherlands. With eight faculties and numerous research institutes it hosts over 19,000 students , more than 3,300 scientists and more than 2,200 people in the support and management staff.The university was established on January 8, 1842 by King William II of the Netherlands as a Royal Academy, with the main purpose of training civil servants for the Dutch East Indies. The school rapidly expanded its research and education curriculum, becoming first a Polytechnic School in 1864, Institute of Technology in 1905, gaining full university rights, and finally changing its name to Delft University of Technology in 1986.Dutch Nobel laureates Jacobus Henricus van 't Hoff, Heike Kamerlingh Onnes, and Simon van der Meer have been associated with TU Delft. TU Delft is a member of several university federations including the IDEA League, CESAER, UNITECH, and 3TU. Wikipedia.

A method of maneuvering a smaller ship which is located alongside a larger ship whereas both ships initially have the same course and the same speed. The smaller ship includes a bow rudder or a Magnus rotor at a bow thereof and is maneuvered away from the larger ship by means of changing the orientation of its bow rudder or activating its Magnus rotor, respectively.

An example device includes a processor configured to receive a plurality of voltage measurements corresponding to nodes in a distribution network, and determine, for each respective node: a value of a first coefficient, based on a previous value of the first coefficient, a minimum voltage value for the node, and a voltage measurement that corresponds to the node, and a value of a second coefficient based on a previous value of the second coefficient, a maximum voltage value for the node, and the voltage measurement. The processor of the example device is also configured to cause an inverter-interfaced energy resource connected to the distribution network to modify its output power based on the value of the first coefficient for each node and the value of the second coefficient for each node.

Transformation of biomass into commodity chemicals using enzymes or cells will be successful if the production process is more attractive than for alternative options to produce these chemicals. Sufficient second generation biomass should be available for a reasonable price, the price will not only be dictated by the biomass production but also by competitive uses of this biomass such as combustion for energy generation. All biomass components should be convertible into product, or otherwise into valuable coproduct. Too high bioreactor investments, due to high O2 requirements or too low productivities, should be avoided. Biochemical processes compete with chemical processes that aim at similar routes from biomass to product. The biochemical process should be more selective or should avoid production and isolation of intermediate chemicals. Scientific discoveries and method development have been very important to increase the rate of development of biochemical routes.

In this tutorial review, the fundamental concepts underlying the principles of green and sustainable chemistry - atom and step economy and the E factor - are presented, within the general context of efficiency in organic synthesis. The importance of waste minimisation through the widespread application of catalysis in all its forms - homogeneous, heterogeneous, organocatalysis and biocatalysis - is discussed. These general principles are illustrated with simple practical examples, such as alcohol oxidation and carbonylation and the asymmetric reduction of ketones. The latter reaction is exemplified by a three enzyme process for the production of a key intermediate in the synthesis of the cholesterol lowering agent, atorvastatin. The immobilisation of enzymes as cross-linked enzyme aggregates (CLEAs) as a means of optimizing operational performance is presented. The use of immobilised enzymes in catalytic cascade processes is illustrated with a trienzymatic process for the conversion of benzaldehyde to (S)-mandelic acid using a combi-CLEA containing three enzymes. Finally, the transition from fossil-based chemicals manufacture to a more sustainable biomass-based production is discussed. © 2012 The Royal Society of Chemistry.
