DNA double helices comprising chimeric GNA/DNA metal-mediated base pairs have been synthesized and characterized (GNA = glycol nucleic acid). The possibility to combine different nucleic acid backbones within one metal-mediated base pair expands the applicability of metal-functionalized nucleic acids.

Complicated potential structure formed at a constriction of positive column of a DC discharge with heated cathode in He at low discharge currents is investigated. According to the potential structure, electrons and ions are accelerated by the electric field and their energy distribution functions acquire multi humped shapes. Additional maximums on distribution functions quickly disappear due to...

The aim of this work was to determine a cost-optimal design the distillation unit Andrussow process. For purpose, feed with mass flow rate 121 t h−1 and concentration ca. 2 wt % hydrogen cyanide (HCN) considered. An approach for process intensification developed goal achieve desired product qualities, while minimizing organonitrile accumulation in column. simple column established base case ext...

This paper presents a parametric study conducted on five Steel Moment Frames (SMFs) varying in height (2-, 4-, 8-, 12-, and 20- story) to assess the interactive effect of column base hysteretic behavior, continuous gravity columns partially restrained beam-column connections their seismic performance. The frame response is examined through sophisticated Nonlinear Time History (NTH) Static Pusho...

This study proposes a fiber beam-column model that takes into account the anisotropy of wood and embedment behavior rocking column to assess impact damage on lateral performance traditional Chinese timber structures. Subsequently, numerical analyses corresponding full-scale quasi-static test framework are conducted verify accuracy this model. By considering factors such as residual deformation ...

Eimer's organ is a small, densely innervated sensory structure found on the glabrous rhinarium of most talpid moles. This structure consists of an epidermal papilla containing a central circular column of cells associated with intraepidermal free nerve endings, Merkel cell neurite complexes, and lamellated corpuscles. The free nerve endings within the central cell column form a ring invested in...

During the first several minutes of an explosive volcanic eruption, the flow in the column above the vent is unsteady even if the discharge from the vent is steady. At a fixed location in the column, parameters such as temperature and ash content change with time until steady flow conditions are established. For conditions believed to be typical of fountain-forming silicic eruptions of intermed...

In this paper we will consider the most known ratios control schemes ((L/D, V/B),(L/D,V/F), Ryskamp’s, and (D/(L+D),V/B)) for binary distillation column and we compare them in the basis of interactions and disturbance propagation. The models for these configurations are deuced using mathematical transformations taking the energy balance structure (LV) as a base model. The dynamic relative magni...

We describe a liquid-chromatographic method involving a new, nonsilica column (XAD-2, Hamilton Co.) for pentobarbital in plasma. Plasma is extracted with chloroform after addition of the internal standard, 5-ethyl-5-p-tolyl-barbituric acid. Acidic drugs are back-extracted into alkali, then chromatographed on the resin-base reversed-phase column. The use of alkaline mobile phase allows enhanced ...
