Tallinn, Estonia

Established in 1918, Tallinn University of Technology is the only technical university in Estonia. TUT, in the capital city of Tallinn, is the nation’s leading academic institution in engineering, business, and public administration. TUT has colleges in Tallinn, Tartu, Kuressaare and Kohtla-Järve. Despite the similar names, Tallinn University and Tallinn University of Technology are separate institutions. Wikipedia.

The importance of biodegradation data as part of the design of safer chemicals is presented using ionic liquids (ILs) as a model study. Structural features that promote/impede IL biodegradation, IL design strategies, methods of biodegradation analysis, properties of IL/surfactant derivatives and computational methods of predicting biodegradation are discussed. The importance of metabolite studies as part of biodegradation assays is highlighted. The relevance of applying the lessons learned developing biodegradable ILs to other chemical classes is proposed. A comprehensive appendix of IL biodegradation data published since 2010 (∼300 ILs) has been compiled. © The Royal Society of Chemistry. Source

Bioreactor system and method for cloning the physiological state of microorganisms comprises in preferred embodiment of a mother-reactor and one or more daughter-reactors with sensors, stirrers, fluid and gas flow channels, scales, pumps, controllers, computer, software, valves and accessory devices. The bioreactors are inter-connected with culture transfer hose. To achieve the method, the mother-reactor is filled with necessary volume, inoculated, stabilised in continuous cultivation, the microbial cultures volume is increased in variable volume cultivation while maintaining constant physiology, microbial culture is transferred from the mother-reactor into the daughter-reactors while maintaining constant physiology, experiment in the daughter reactor follows. After the experiment daughter-reactors are sterilized and rinsed. During the experiment culture volume in the mother-reactor is increased anew, after the experiment in the daughter-reactors is finished another culture transfer follows and next experiment is conducted. This sequencevariable volume cultivation, culture transfer, experimentis repeated until necessary data has been acquired.

The invention describes use of RNA silencing suppressors or interactors of the suppressors to bring the expression of microRNAs involved in any disease, including malignant neoplasia, back to its normal level. More specifically the present invention provides a method to regulate many miRNAs at the same time. Most of the suppressors according to this invention are coded by plant viruses that unexpectedly can affect RNA silencing and modulate miRNA expression levels in mammalian cells. Also suppressors of endogenous origin are described as able to modulate miRNA expression levels.

A method and device for high speed broadband testing of systems and substances using a binary, spectrally sparse sequence (SSS) as a periodic excitation waveform. The sequences with controllable frequency and magnitude spectra content are designed by component manipulation method or by edge manipulation method. The excitation waveform is typically pre-calculated, and kept in waveform memory, from where it is shifted out into digital to physical quantity converter (DQC). The sparse spectrum of the SSS makes it easy to create plenty of uncorrelated frequency sets with adjacent, but sufficiently different frequencies to form multi-path test systems, where all the paths can be measured simultaneously. The response of the sample under test (SUT) is sampled and the complex transfer function is calculated directly or indirectly via Impulse Response by Discrete Fourier Transform technique and its derivatives. The sequence bit interval and sampling interval have a predetermined ratio.

A method is provided for measuring a frequency response of an object, the method involving: generating an excitation signal having relatively fast changing frequency, defined by a time-domain function; generating at least one reference signal, having a waveform corresponding to the excitation signal; introducing the excitation signal into the object, receiving a response signal from the object; analyzing said response signal in a signal analyzer by correlating the response signal with at least one reference signal during a relatively short sliding time-domain window.
