In der Grünfutterernte nehmen Scheibenmähwerke aufgrund der spezifischen Einsatzvorteile eine zunehmende Rolle ein. Sie arbeiten nach dem Prinzip des freien Schnitts, bei dem die Trägheits- und Biegekräfte der Grashalme als Gegenkräfte genutzt werden. Diese Technologie zeichnet sich allerdings auch durch hohe Verlustl…
Für die N2O-Emissionen aus der Lagerung von Festmist wurde anhand einer Literaturstudie geprüft, ob nationale Emissionsfaktoren für Deutschland definiert werden können. In Deutschland überwiegen stroharme Festmiste aus der Rinder- und Schweinehaltung, die in der Regel bis zu 6 Monate in offenen Mieten ohne weitere Beh…
Leucaena leucocephala wood char (LC) was produced by a pyrolysis process at 1000 °C. The characteristics of char were identified using scanning electron microscopy (SEM), fourier transform infrared (FTIR) spectroscope, ultimate analysis and BET surface area. Adsorption of methylene blue (MB) dye onto produced LC was t…
Permasalahan yang sering muncul pada saat mengoperasikan mesin Thermoforming pada industri kecil coklat praline \nadalah menentukan kondisi operasional setting parameter yang terbaik sehingga akan diperoleh kualitas kualitas hasil \ncetakan plastik yang baik, tanpa cacat, dan umur pakai cetakan lama. \nMetode Taguchi…
The emergence of carrier pairing from the electronically inhomogeneous phase of lightly hole-doped copper oxides has been investigated through magnetoresistance measurements on 1222-type ruthenocuprates ${\mathrm{RuSr}}_{2}{(R,\mathrm{Ce})}_{2}{\mathrm{Cu}}_{2}{\mathrm{O}}_{10\ensuremath{-}\ensuremath{\delta}}$, princ…
Molecular Imaging (MI) is an emerging technology for the early detection of disease, staging of the disease, and for monitoring response to therapy. It also offers a non-invasive method to detect in vivo biological functions and processes at a molecular level. The use of MI requires careful selection of targeting mole…
Abstract Warm rubidium vapours are known to be a versatile medium for a variety of experiments in atomic physics and quantum optics. Here we present experimental results on producing the frequency converted light for quantum applications based on spontaneous and stimulated processes in rubidium vapours. In particular,…
At the request of the authors this Response is being retracted. This action is taken because the values of data points in Fig. 2 of the Response do not appear to match the values in the original article from which they were taken, the parameter B in the Arrhenius law can be defined arbitrarily making the resulting act…
The catalytic decomposition of ozone to molecular oxygen over catalytic mixture containing manganese, copper and nickel oxides was investigated in the present work. The catalytic activity was evaluated on the basis of the decomposition coefficient which is proportional to ozone decomposition rate, and it has been alre…
Results of quasi-static numerical simulation of spin tests of model disk made from high-temperature forged alloy are presented. To determine stress-strain state of disk during loading finite element analysis is used. Simulation of elastic-plastic strain fields was carried out using incremental theory of plasticity wit…
The results of investigation of the effect of additions of lithium compounds (LiNO3, LiCl, LiBr, LiF) in the KF–AlF3 eutectic on the spreading of the brazing alloy, strength and microstructure of brazed joints are presented. The dependences of the spreading area of the brazing alloy on the content of the investigated…
The Monte Carlo method to define quantitative characteristics of fiber intersections in the fiber rubcon structure taking into account the defined sizes of the samples was shown, adapted and applied in the paper. Dependence graphs of the amount of areas with dimensions smaller than the diameter of the allowable hetero…
A facile strategy for the fabrication of ultralarge (edge length >50 μm), single-crystalline Ag nanomembranes is reported in this work. The Ag nanomembrane with an atomically smooth surface demonstrates a much longer surface plasmonic propagation length as compared to vacuum-deposited polycrystalline Ag film, represen…
In the literature, there are experimental studies, confirming the significant effect of the degree of concentration of the active components of corrosive on the corrosion process. These results are presented in tables and graphs that describe the dependencies of the time before corrosion damage on the mechanical stres…
We studied the spin torque switching in dual MgO layer based magnetic tunnel junctions (MTJs) by incorporating an ultra-thin (0.5 nm) Ta layer at the CoFeB free layer/top MgO layer interface. The Ta incorporated MTJ showed a significant reduction (∼30%) in critical switching current density (JC0 ) as compared to that…
An unperturbed piece of glass is optically isotropic. Birefringence can be induced by breaking this symmetry, for example by applying a uniaxial stress to the glass. An empirical model exists which predicts when oxide glasses will exhibit positive, negative or zero birefringence under stress. This model has been used…
C-Glucosides are glucose-containing glycosides that have carbon–carbon bonds between the anomeric carbon of the sugar moieties and aglycon, rendering the molecules remarkably stable against hydrolysis by enzymes or acids. In this work, we showed the production ofC-glucosides of flavonoids and related compounds (i.e.,…
In the scope of application of technical textiles, Non-Crimp Fabrics are increasingly used. In general, NCF exhibit excellent load bearing properties, but caused by the manufacturing process, there are some remaining disadvantages which have to be reduced. Regarding to this, a novel technique of processing NCF was dev…

Im Vergleich zum Grubber benötigt die untersuchte Kurzscheibenegge etwas geringere Zugkräfte. Die Vertikalkräfte der Grubberwerkzeuge belasten die Walze zusätzlich und sorgen für eine bessere Rückverfestigung. Die Oberflächenkontur wurde mit einem vollautomatischen Profilmessgerät erfasst. Bei tieferer Bearbeitung hin…
