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 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

The final ATLAS Run 1 measurements of Higgs boson production and couplings in the decay channel H→ZZ*→ℓ+ℓ-ℓ′+ℓ′-, where ℓ, ℓ′=e or μ, are presented. These measurements were performed using pp collision data corresponding to integrated luminosities of 4.5 and 20.3 fb-1 at center-of-mass energies of 7 and 8 TeV, respectively, recorded with the ATLAS detector at the LHC. The H→ZZ*→4ℓ signal is observed with a significance of 8.1 standard deviations, with an expectation of 6.2 standard deviations, at mH=125.36 GeV, the combined ATLAS measurement of the Higgs boson mass from the H→γγ and H→ZZ*→4ℓ channels. The production rate relative to the Standard Model expectation, the signal strength, is measured in four different production categories in the H→ZZ*→4ℓ channel. The measured signal strength, at this mass, and with all categories combined, is 1.44-0.33+0.40.\n

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.

Lorentz symmetry requires the space-time structure to be the same for all observers, but, on the other hand, various quantum gravity theories suggest that it may be violated when approaching the Planck scale. Even a small violation of Lorentz Invariance (LI) could easily affect the Ultra High Energy Cosmic Rays (UHECRs) propagation on a cosmological scale. Moreover, at the extreme energies, like those available in the collision of UHECRs with atmosphere, one should also expect a change in the interactions and, therefore, in the development of extensive air showers. For the first time, this effect has been studied using the muon content of air showers measured at the Pierre Auger Observatory. After having introduced Lorentz Invariance Violation (LIV) as a perturbation term in the single particle dispersion relation, a library of simulated showers with different energies, primary particles and LIV strengths has been produced.

The antioxidant of water- soluble extract from the debris of Myrica rubra leaves oil extracts was determined.And then,the antibacterial activity of petroleum ether,dichloromethane,ethyl acetate and n- butanols’ water- soluble extracts of residues from Myrica rubra leaves was measured and analyzed respectively. Moreover,anti- corrosion test of extract layer,which displayed obvious antibacterial effect,was evaluated by applying it to the meat. The results showed that DPPH radical scavenging activity and hydroxyl radical scavenging activity of water- soluble extract gradually elevated up to 80% between 0.1 to 5mg /mL. The antimicrobial experiment demonstrated that ethyl acetate extracts and n- butano extracts had a stronger antimicrobial performance and a wider antimicrobial spectrum. However,meat anti sepsis effect of ethyl acetate was better than potassium sorbate in the same concentration. And n- butano extracts have no significant difference with potassium sorbate.

A search for exclusive two-photon production via photon exchange in proton-proton collisions, pp → pγγp with intact protons, is presented. The data correspond to an integrated luminosity of 9.4 fb-1 collected in 2016 using the CMS and TOTEM detectors at a center-of-mass energy of 13 TeV at the LHC. Events are selected with a diphoton invariant mass above 350 GeV and with both protons intact in the final state, to reduce backgrounds from strong interactions. The events of interest are those where the invariant mass and rapidity calculated from the momentum losses of the forward-moving protons match the mass and rapidity of the central, two-photon system. No events are found that satisfy this condition. Interpreting this result in an effective dimension-8 extension of the standard model, the first limits are set on the two anomalous four-photon coupling parameters.

Broadband dielectric spectroscopy of the Rb3H(SeO4)2 crystal was determined across the phase transition into superprotonic phase. The AC conductivity scaling confirms the thermally activated proton conductivity and the first universality law in both phases.

The minimal U(1)(B-L) extension of the Standard Model (B-L-SM) offers an explanation for neutrino mass generation via a seesaw mechanism, it also offers two new physics states, namely an extra Higgs boson and a new Z' gauge boson. The emergence of a second Higgs particle as well as a new Z' gauge boson, both linked to the breaking of a local U(1)(B-L) symmetry, makes the B-L-SM rather constrained by direct searches in Large Hadron Collider (LHC) experiments. We investigate the phenomenological status of the B-L-SM by confronting the new physics predictions with the LHC and electroweak precision data. Taking into account the current bounds from direct LHC searches, we demonstrate that the prediction for the muon (g - 2)(mu) anomaly in the B-L-SM yields at most a contribution of approximately 8.9 x 10(-12), which represents a tension of 3.28 standard deviations, with the current uncertainty, by means of a Z' boson if its mass is in the range of 6.3 to 6.5 TeV, within the reach of future LHC runs. This means that the B-L-SM, with heavy yet allowed Z' boson mass range, in practice, does not resolve the tension between the observed anomaly in the muon (g - 2)(mu) and the theoretical prediction in the Standard Model. Such a heavy Z' boson also implies that the minimal value for the new Higgs mass is of the order of 400 GeV.
