For the purposes of trace analysis of 1,4-androstadiene-3,17-dione (ADD), 1,4-androstadiene-3-one-17β-ol (Boldenone) and 17-β-estradiol in water, waste water, soil and for the further phytosterols transformation studies the enolisation-silylation reaction was studied using MSTFA and BSTFA with different catalysts as derivatization reagents. The different reaction conditions and stability of the products was also studied using GC-MS technique.

We present the first measurement of event-by-event fluctuations in the kaon sector in Pb - Pb collisions at root S-NN = 2.76 TeV with the ALICE detector at the LHC. The robust fluctuation correlator nu(dyn) is used to evaluate the magnitude of fluctuations of the relative yields of neutral and charged kaons, as well as the relative yields of charged kaons, as a function of collision centrality and selected kinematic ranges. While the correlator nu(dyn) [K+,K-] exhibits a scaling approximately in inverse proportion of the charged particle multiplicity, nu(dyn)[K-S(0),K-+/-] features a significant deviation from such scaling. Within uncertainties, the value of nu(dyn) [K-S(0), K-+/-] is independent of the selected transverse momentum interval, while it exhibits a pseudorapidity dependence. The results are compared with HIJING, AMPT and EPOS-LHC predictions, and are further discussed in the context of the possible production of disoriented chiral condensates in central Pb - Pb collisions.

Microalgae form a wide group of photosynthetic microorganisms, which includes prokaryotic cyanobacteria (e.g. genus Arthrospira) as well as eukaryotic unicellular algae (e.g. genus Chlorella). Microalgae can be regarded as microplants able to convert carbon dioxide and water into organic compounds via photosynthesis. Nevertheless, comparing to higher plants (agricultural crops) the microalgae have much higher areal productivities, high content of proteins, vitamins, antioxidants, polyunsaturated fatty acids and other health-promoting components. Moreover, they can be produced in non-arable areas requiring low-cost inputs. To reach high productivities of microalgal cultures, it is necessary to supply them with sufficient illumination, carbon dioxide and minerals in culturing media. Nowadays microalgae for human and/or animal nutrition are produced in different types of photobioreactors where previously mentioned suitable conditions are ensured along with appropriate mixing and oxygen release. In order to decrease the cultivation cost of microalgae, it was proven that different kinds of flue gasses can be used as a carbon dioxide source, sunlight is the source of energy (illumination) and in some cases suitable waste water can be used as the source of mineral nutrients. Considering current state of knowledge, Arthrospira (spirulina, often rated among superfoods) seems to be the most promising microalga for widespread cultivation in large scale as for its cultivation and harvesting no expensive technologies are needed.

The Great Ball Game Hall of Prague Castle, dating from the years 1567–1569 and built for Emperor Maximilian II, presents an exceptional architectural realization. Apart from the representative appearance of the Great Ball Game Hall also its unusual scale is singular: It is roughly twice as long as was the custom and as was recommended by the Trattato del giuoco della palla by Antonio Scaino (Ferrara 1555). The dimensions of the building are linked to the question of how the Great Ball Game Hall was actually used. Archival sources from the time of the reign of Emperor Rudolf II indicate that it was used probably for the pallone game and not for the game of tennis. From the framework given by the historiography of Renaissance sports and recreation evolves the hypothesis that also covered buildings for the pallone game existed – contrary to the dominant opinion that the game was played exclusively outdoors.

The international collaboration designing and constructingthe Deep Underground Neutrino Experiment (DUNE) at the Long-BaselineNeutrino Facility (LBNF) has developed a two-phase strategy towardthe implementation of this leading-edge, large-scale scienceproject. The 2023 report of the US Particle Physics ProjectPrioritization Panel (P5) reaffirmed this vision and stronglyendorsed DUNE Phase I and Phase II, as did the European Strategy forParticle Physics. While the construction of the DUNE Phase I is wellunderway, this White Paper focuses on DUNE Phase II planning. DUNEPhase-II consists of a third and fourth far detector (FD) module, anupgraded near detector complex, and an enhanced 2.1 MW beam. Thefourth FD module is conceived as a “Module of Opportunity”, aimedat expanding the physics opportunities, in addition to supportingthe core DUNE science program, with more advanced technologies. Thisdocument highlights the increased science opportunities offered bythe DUNE Phase II near and far detectors, including long-baselineneutrino oscillation physics, neutrino astrophysics, and physicsbeyond the standard model.

This paper deals with stability of stochastic optimization problems in a general setting. Objective function is defined on a metric space and depends on a probability measure which is unknown, but, estimated from empirical observations. We derive stability results without precise knowledge of problem structure and without measurability assumption. The setup is illustrated on consistency of a $/varepsilon$-$M$-estimator in linear regression model.

Facultative paedomorphosis is an environmentally induced polymorphism that is well known for many caudate species including newts. Although facultative paedomorphosis has been documented in some smooth-newt populations, records of entirely paedomorphic populations outside the Balkans are limited. Here we present the first evidence of a paedomorphic population of the smooth newt in the Czech Republic with discussion of potential causes that need to be further tested.

The study interprets the art historical method developed by Oldřich Stefan in the late 1930s and early 1940s as an amplification of the method of the Vienna School of art history. Stefan was professionally an architect, but during his studies in 1920s he also attended art-historical seminar of Vojtěch Birnbaum, a pupil of Alois Riegl and Franz Wickhoff. Birnbaum at the Charles University in Prague developed Riegl’s method of art history, mostly represented by his notion of a ‘baroque principle’ in the history of architecture, published in 1924. The influence of the Vienna School of art history in Prague was elaborated also by Antonín Matějček, a follower of Max Dvořák and colleague of Birnbaum at the Prague University. The tradition of the continuation of the Vienna School in Czech art historiography is widely researched mostly in connection to the conceptions of Matějček’s students, who influenced Czech art history in the second half of the 20th century, unlike Birnbaum’s students. However, beside Růžena Vacková it was Oldřich Stefan who profoundly connected his art-historical thinking to the Vienna School tradition, mostly to Birnbaum’s and also Dvořák’s thinking – the methodological foundations of his own theory Stefan elaborated in connection with the historical disruption of the known world by the Second World War. How the study suggests, Stefan amplified the methodological assumptions of the Vienna School in order to restore the impaired reality of the advanced 20th century.

The ALICE Collaboration has measured the energy dependence of exclusive photoproduction of J/psi vector mesons off proton targets in ultra-peripheral p-Pb collisions at a centre-of-mass energy per nucleon pair =5.02 TeV. The e+e- and mu+mu- decay channels are used to measure the cross section as a function of the rapidity of the J/psi in the range -2.5
