From the obtained data is visible, that the given species of a plant is endemic. It is established, that dynamics of accumulation of lagochirzin in phytomass accrues from the beginning to the middle of the growing season. The chemical analysis of L.setulosus on a localization of lagochirzin in various organs of a plant, has shown, that the greatest quantity of lagochirzin collects in calyx lobes of the plants. Also it is established, that L.setulosus can be cultivated in the conditions of the typical sierozem, a mineral food is necessary for the given species of plants of Lagochilus genus, except nitric fertilizers. Comparative studying of wild-growing and cultural forms of L.setulosus has shown, that in the cultivated phytomass of plants the maintenance of lagochirzin on 17-20 \% higher than in the wild-growing species.}, language = {en} } @article{Ritz2000, author = {Ritz, Thomas}, title = {Personalized information services : an electronic information commodity and its production}, series = {International Journal of E-Business Strategy Management}, volume = {2}, journal = {International Journal of E-Business Strategy Management}, number = {2}, issn = {1467-0305}, year = {2000}, language = {en} } @article{AkimbekovDigelSavitkayaetal.2013, author = {Akimbekov, Nuraly S. and Digel, Ilya and Savitkaya, I.S. and Zhubanova, A.A. and Tastambek, K.T.}, title = {Investigations of LPS endotoxin elimination in the flowing column conditions with the sorbent on the basis of carbonized rice husk}, series = {KazNU Bulletin.

Consequently, the design space for future aircraft is expanded considerably, as serial hybrid-electric, parallel hybrid-electric, fully electric, and conventional propulsion systems must all be considered. While the best propulsion system depends on a multitude of requirements and considerations, trends can be observed for certain types of aircraft and certain types of missions. This Paper provides insight into some factors that drive a new design toward either conventional or hybrid propulsion systems. General aviation aircraft, regional transport aircraft vertical takeoff and landing air taxis, and unmanned aerial vehicles are chosen as case studies. Typical missions for each class are considered, and the aircraft are analyzed regarding their takeoff mass and primary energy consumption. For these case studies, a high-level approach is chosen, using an initial sizing methodology. Only parallel-hybrid-electric powertrains are taken into account. Aeropropulsive interaction effects are neglected. Results indicate that hybrid-electric propulsion systems should be considered if the propulsion system is sized by short-duration power constraints. However, if the propulsion system is sized by a continuous power requirement, hybrid-electric systems offer hardly any benefit.}, language = {en} } @article{BongaertsBovenbergKraemeretal.2002, author = {Bongaerts, Johannes and Bovenberg, Roel and Kr{\"a}mer, Marco and M{\"u}ller, Ulrike and Raeven, Leon and Wubbolts, Marcel}, title = {Metabolic engineering to produce fine chemicals in Escherichia coli}, series = {Chemie - Ingenieur - Technik (CIT)}, volume = {Vol. 74}, journal = {Chemie - Ingenieur - Technik (CIT)}, number = {Iss. 5}, issn = {1522-2640 (E-Journal); 0009-286X (Print)}, pages = {694}, year = {2002}, language = {en} } @article{BialonskiWellmerElgeretal.2006, author = {Bialonski, Stephan and Wellmer, J{\"o}rg and Elger, Christian E. and Lehnertz, Klaus}, title = {Interictal focus localization in neocortical lesional epilepsies with synchronization cluster analysis}, series = {Epilepsia}, volume = {47}, journal = {Epilepsia}, issn = {0013-9580}, pages = {36}, year = {2006}, language = {en} } @article{FerreinBoehnstedtLakemeyer2007, author = {Ferrein, Alexander and B{\"o}hnstedt, Lutz and Lakemeyer, Gerhard}, title = {Options in readylog reloaded -- generating decision-theoretic plan libraries in golog / B{\"o}hnstedt, Lutz ; Ferrein, Alexander ; Lakemeyer, Gerhard}, series = {KI 2007: advances in artificial intelligence : 30th Annual German Conference on AI, KI 2007, Osnabr{\"u}ck, Germany, September 10 - 13, 2007 ; proceedings}, journal = {KI 2007: advances in artificial intelligence : 30th Annual German Conference on AI, KI 2007, Osnabr{\"u}ck, Germany, September 10 - 13, 2007 ; proceedings}, publisher = {Springer}, address = {Berlin}, isbn = {978-3-540-74564-8}, pages = {352 -- 366}, year = {2007}, language = {en} } @article{Heuermann1995, author = {Heuermann, Holger}, title = {LZY: A Self-Calibration Approach in Competition to the LRM Method for On-Wafer Measurements}, pages = {129 -- 136}, year = {1995}, language = {en} } @article{WolfFoltzSchlicketal.2002, author = {Wolf, Martin R. and Foltz, Christian and Schlick, Christopher and Luczak, Holger}, title = {Development and evaluation of a groupware system to support chemical design processes / Wolf, Martin ; Foltz, Christian ; Schlick, Christopher ; Luczak, Holger}, series = {International Journal of Human-Computer Interaction . 14 (2002), H. 2}, journal = {International Journal of Human-Computer Interaction . 14 (2002), H. 2}, publisher = {-}, isbn = {1044-7318}, pages = {181 -- 198}, year = {2002}, language = {en} } @article{BongaertsZoschkeWeidneretal.1995, author = {Bongaerts, Johannes and Zoschke, Sascha and Weidner, Uwe and Linden, Gottfried}, title = {Transcriptional regulation of the proton translocating NADH}, series = {Molecular microbiology}, volume = {Vol. 16}, journal = {Molecular microbiology}, number = {Iss. 3}, issn = {1365-2958 (E-Journal); 0950-382x (Print)}, pages = {521 -- 534}, year = {1995}, language = {en} } @article{Staat1996, author = {Staat, Manfred}, title = {Problems and Chances for Probabilistic Fracture Mechanics in the Analysis of Steel Pressure Boundary Reliability}, series = {Technical feasibility and reliability of passive safety systems for nuclear power plants.

The morphology of different layered RTDs is analyzed by scanning electron microscopy. The sensor performance and lifetime of the RTD is characterized both under ambient atmospheric conditions between 30°C and 43°C, and wet tissue-like conditions with a constant temperature regime of 37°C. The latter triggers the degradation process of the magnesium-based layers. The 3-layers RTDs on a PLA substrate could achieve a lifetime of 8.5 h.

The influence of different curing parameters of the carbon electrodes on the resulting biosensor characteristics is studied. The morphology of the electrodes is investigated by scanning electron microscopy, and the biosensor performance is examined by amperometric measurements of glucose (0.5-10 mM) in phosphate buffer solution, pH 7.4, at an applied potential of 1.2 V versus a Ag/AgCl reference electrode. Instead of Ecoflex, fibroin, PLA, and wound adhesive are tested as alternative encapsulation compounds: a series of swelling tests with different fibroin compositions, PLA, and Ecoflex has been performed before characterizing the most promising candidates by chronoamperometry. Therefore, the carbon electrodes are completely covered with the particular encapsulation material.

The used multicell arrangement enables a multiplexed electrochemical characterization of up to sixteen EISCAPs. Different enzyme coverages have been achieved by means of parallel electrical connection of bare and enzyme-covered single EISCAPs in diverse combinations. As predicted by the model, with increasing the enzyme coverage, both the shift of capacitance-voltage curves and the amplitude of the constant-capacitance signal increase, resulting in an enhancement of analyte sensitivity of the EISCAP biosensor.

The manuscript describes a simple alternative to these common workflows by using NMR signal of another active nuclei of calibration compound. For example, for any arbitrary compound quantification by NMR can be based on the use of an indirect concentration referencing that relies on a solvent having both 1H and 2H signals. To perform high-quality quantification, the deuteration level of the utilized deuterated solvent has to be estimated. In this contribution the new method was applied to the determination of deuteration levels in different deuterated solvents (MeOD, ACN, CDCl3, acetone, benzene, DMSO-d6). Isopropanol-d6, which contains a defined number of deuterons and protons, was used for standardization. Validation characteristics (precision, accuracy, robustness) were calculated and the results showed that the method can be used in routine practice. Uncertainty budget was also evaluated. In general, this novel approach, using standardization by 2H integral, benefits from reduced sample preparation steps and uncertainties, and can be applied in different application areas (purity determination, forensics, pharmaceutical analysis, etc.).}, language = {en} }
