The implementation of social dialogue in the institution of higher education in the development of social partnership
Increasing information awareness of the development of social partnership is a necessary and vital result of twenty years of development of social partnership in Russia. Conferences (roundtable discussions) of stakeholders of organizations, members of social partnership at the regional level can be the means of increasing information awareness. The staff of the University has a powerful resource in this area. The paper describes the project of the conference on exchange of experiences in research and development of social partnership in the region. Professional playground of the University is the best venue for such conference.Повышение информационной осведомленности о развитии социального партнерства является необходимым и насущным результатом двадцатилетнего развития социального партнерства в России. Средством повышения информационной осведомленности может быть конференция (круглый стол) стейкхолдеров организации, участников социального партнерства на региональном уровне. Персонал вуза обладает мощным информационным ресурсом в этой области. В статье описан проект конференции по обмену опытом исследования и развития социального партнерства в регионе. Профессиональная площадка вуза является оптимальным пространством для проведения такой конференции
XUV digital in-line holography using high-order harmonics
A step towards a successful implementation of timeresolved digital in-line
holography with extreme ultraviolet radiation is presented. Ultrashort XUV
pulses are produced as high-order harmonics of a femtosecond laser and a
Schwarzschild objective is used to focus harmonic radiation at 38 nm and to
produce a strongly divergent reference beam for holographic recording.
Experimental holograms of thin wires are recorded and the objects
reconstructed. Descriptions of the simulation and reconstruction theory and
algorithms are also given. Spatial resolution of few hundreds of nm is
potentially achievable, and micrometer resolution range is demonstrated.Comment: 8 pages, 8 figure
Haemoptysis as Complication of Wire-Guided Pulmonary Vein Orifice Cryoballoon Ablation in Complex Anatomy: a Clinical Case Series
Background. Cryoballoon ablation of pulmonary vein orifices is an effective measure in atrial fibrillation but associates with risks of interventional complications, including haemoptysis. The described clinical case series presents novel evidence to revisit the complication sources.Materials and methods. Four haemoptysis-complicated cryoballoon ablations of pulmonary vein orifice have been analysed retrospectively. Interventions completed in a common clinical protocol with no additional postoperative complications.Results. Fluoroscopy revealed a loop-formed balloon-supporting end of guidewire located in peripheral lower lobe of right lung. Postoperative chest computed tomography also depicted the main lung blood volume confined in right lower lobe, thus indicating pulmonary damage by the guidewire.Discussion. Pulmonary vein anatomy is diverse and can greatly sophisticate the cryoballoon ablation procedure with a peculiar balloon navigation in left atrium. An optimal pulmonary vein orifice occlusion can be attained with guidewire, albeit incurring complications in form of haemoptysis.Conclusions. The appliance advancement towards lung periphery associates with a higher risk of haemoptysis and bleeding. Perioperative haemoptysis and bleeding are most likely associated with mechanical injury to minor veins and require further investigation
Modern venomics – Current insights, novel methods and future perspectives in biological and applied animal venom research
Venoms have evolved >100 times in all major animal groups, and their components, known as toxins, have been fine-tuned over millions of years into highly effective biochemical weapons. There are many outstanding questions on the evolution of toxin arsenals, such as how venom genes originate, how venom contributes to the fitness of venomous species, and which modifications at the genomic, transcriptomic, and protein level drive their evolution. These questions have received particularly little attention outside of snakes, cone snails, spiders, and scorpions. Venom compounds have further become a source of inspiration for translational research using their diverse bioactivities for various applications. We highlight here recent advances and new strategies in modern venomics and discuss how recent technological innovations and multi-omic methods dramatically improve research on venomous animals. The study of genomes and their modifications through CRISPR and knockdown technologies will increase our understanding of how toxins evolve and which functions they have in the different ontogenetic stages during the development of venomous animals. Mass spectrometry imaging combined with spatial transcriptomics, in situ hybridization techniques, and modern computer tomography gives us further insights into the spatial distribution of toxins in the venom system and the function of the venom apparatus. All these evolutionary and biological insights contribute to more efficiently identify venom compounds, which can then be synthesized or produced in adapted expression systems to test their bioactivity. Finally, we critically discuss recent agrochemical, pharmaceutical, therapeutic, and diagnostic (so-called translational) aspects of venoms from which humans benefit
First Observation of Self-Amplified Spontaneous Emission in a Free-Electron Laser at 109 nm Wavelength
We present the first observation of Self-Amplified Spontaneous Emission
(SASE) in a free-electron laser (FEL) in the Vacuum Ultraviolet regime at 109
nm wavelength (11 eV). The observed free-electron laser gain (approx. 3000) and
the radiation characteristics, such as dependency on bunch charge, angular
distribution, spectral width and intensity fluctuations all corroborate the
existing models for SASE FELs.Comment: 6 pages including 6 figures; e-mail: [email protected]
Photoactive Properties of Transport Sol-Gel Layers Based on Strontium Titanate for Perovskite Solar Cells
In this work, we have investigated the photocurrent and spectral sensitivity of the
silicon/SrTiO3:xNb/perovskite structures. The sol–gel method carried out the deposition of undoped
SrTiO3 layers as well as niobium-doped (SrTiO3:Nb) layers at atomic concentrations of 3 and 6% Nb.
The perovskite layer, CH3NH3PbI3_xClx, has been deposited by the vacuum co-evaporation technique. The layers have been characterized by scanning electron microscopy and X-ray diffraction
measurements. The volt–ampere characteristics and spectral sensitivity of the fabricated samples
have been measured under illumination with selective wavelengths of 405, 450, 520, 660, 780, 808, 905,
980, and 1064 nm of laser diodes. We have shown that for different configurations of applied voltage
between silicon, SrTiO3:xNb, and CH3NH3PbI3_xClx, the structures are photosensitive ones with
a variation of photocurrent from microamperes to milliamperes depending on Nb concentration in
SrTiO3, and the highest photocurrent and spectral sensitivity values are observed when a SrTiO3:Nb
layer with 3 at.% of Nb is used. A possible application of the proposed structure with a SrTiO3:Nb
layer for perovskite solar cells and photodetectors is being discussed
