Bibliotekāru iesaistīšanās darbā publiskajās viena darbinieka bibliotēkās
2021
Bibliotekāru iesaistīšanās darbā viena darbinieka bibliotēkās ir viens no bibliotēkas ikdienas procesu kvalitatīvas un efektīvas izpildes aspektiem. Apzinot personāla iesaistīšanās faktorus, ir iespējams noteikt un uzlabot bibliotekāru iesaistīšanos darbā. Pētījuma mērķis ir noskaidrot, vai viena darbinieka publiskajās bibliotēkās strādājošie bibliotekāri ir darbā iesaistījušies, un kādi faktori ietekmē to iesaistīšanos darbā. Pētījuma ievaros veikta viena darbinieka publisko bibliotēku bibliotekāru anketēšana un intervijas. Pētījuma rezultāti norāda, ka viena darbinieka publisko bibliotēku bibliotekāri ir darbā iesaistījušies vidēji divas dienas nedēļā, tomēr ir vairāki pastāvoši faktori, …
Highly occupied gauge theories in 2 + 1 dimensions : a self-similar attractor
2019
Motivated by the boost-invariant Glasma state in the initial stages in heavy-ion collisions, we perform classical-statistical simulations of SU(2) gauge theory in 2+1 dimensional space-time both with and without a scalar field in the adjoint representation. We show that irrespective of the details of the initial condition, the far-from-equilibrium evolution of these highly occupied systems approaches a unique universal attractor at high momenta that is the same for the gauge and scalar sectors. We extract the scaling exponents and the form of the distribution function close to this non-thermal fixed point. We find that the dynamics are governed by an energy cascade to higher momenta with sc…
Time-like Proton Form Factors with Initial State Radiation Technique
2022
Electromagnetic form factors are fundamental quantities describing the internal structure of hadrons. They can be measured with scattering processes in the space-like region and annihilation processes in the time-like region. The two regions are connected by crossing symmetry. The measurements of the proton electromagnetic form factors in the time-like region using the initial state radiation technique are reviewed. Recent experimental studies have shown that initial state radiation processes at high luminosity electron-positron colliders can be effectively used to probe the electromagnetic structure of hadrons. The BABAR experiment at the B-factory PEP-II in Stanford and the BESIII experim…
Formaldehyde and total aldehydes in indoor air of public environments by voltammetry
2014
The proposed method involves active sampling, where a sampling pump is used to pull air through a solution and voltammetric analysis of the obtained solutions. No interferences have been observed. In addition, very little sample preparation is required. Analyses were performed in 19 indoor stations and one in outdoor. Measurements were carried out on University environments: Museum of Chemistry, Zoological Museum, libraries, laboratories, corridors, meeting rooms, photocopying room, machine shop and terrace. Formaldehyde concentrations in analyzed samples ranged from 2.6 to 85 μg m-3 (median = 32 μg m-3), while the sum of others aldehydes ranged from 2 to 25 μg m-3 (median =2.4 μg m-3). In …
