Razvoj zdravog napitka sirutke sa Lactobacillus rhamnosus, Bifidobacterium bifidum i Propionibacterium freudenreichii subsp. shermanii

Whey beverage was prepared by utilizing Lactobacillus rhamnosus NCDO 243, Bifidobacterium bifidum NCDO 2715 and Propionibacterium freudenreichii subsp. shermanii MTCC 1371 in order to make a fermented probiotic healthy drink. The product made with 4 % mixed culture (1:1:1) inoculated (initial count - lactobacilli 6.2 x 107 CFU/mL, bifidobacteria 5.4 x 107 CFU/mL, propionibacteria 3.9 x 107 CFU/mL) in deprotienized whey (4.6 % lactose, 0.62 % ash, 0.48 % fat and 0.5 % protein) adjusted to pH 6.4 and incubated at 37 °C for 8 h has a good technological and dietetic criteria required for a probiotic product. Total bacterial count, lactobacilli count, bifidobacteria count, propionibacteria count, titratable acidity, β-D galactosidase activity, concentration of lactic acid and sensory properties were monitored during storage period. The whey beverage fermented for 8 h and prepared with 4 % inoculum of mixed culture (1:1:1) met the probiotic criterion by maintaining each type of bacterial population at counts greater than 108 CFU/mL up to 10 days of storage period. The titratable acidity as well as sensory properties did not change appreciably during first 7 days of storage. At the end of 15 days of storage, slight acidification was detected, although the beverage still retained an acceptable flavour.Napitak sirutke je pripremljen korištenjem Lactobacillus rhamnosus NCDO 243, Bifidobacterium bifidum NCDO 2715 i Propionibacterium freudenreichii subsp. shermanii MTCC 1371 u svrhu pripravljanja probiotskog zdravog napitka. Proizvod je pripravljen s 4 % inokuluma mješovite kulture (1:1:1, početni broj - laktobacili 6,2 x 107 CFU/mL, bifidobacteria 5,4 x 107 CFU/mL, propionibacteria 3,9 x 107 CFU/mL) u deproteiniziranoj sirutki (4,6 % laktoze, 0,62 % pepela, 0,48 % masti i 0,5 % proteina) prilagođenog pH (6,4) i inkubiranog na 37 °C kroz 8 h radi postizanja dobrih tehnoloških i dijetetskih kriterija za dobivanje probiotičkog proizvoda. Tijekom skladištenja promatrani su ukupni broj bakterija, broj laktobacila, broj bifidobakterija, koncentracija mliječne kiseline te senzorska svojstva. Sirutka fermentirana s 4 % inokuluma mješovite kulture tijekom 8 sati postigla je kriterije zadane za probiotičke napitke, s brojem svakog pojedinog soja većim od 108 CFU/mL tijekom 10 dana skladištenja. Titracijska kiselost i senzorska svojstva nisu se značajno mijenjala tijekom 7 dana skladištenja. Na kraju 15-tog dana skladištenja, pojavila se blaga kiselost iako je napitak još uvijek bio ocijenjen kao prihvatljiv obzirom na okus

Search for neutral resonances decaying into a Z boson and a pair of b jets or τ leptons

A search is performed for a new resonance decaying into a lighter resonance and a Z boson. Two channels are studied, targeting the decay of the lighter resonance into either a pair of oppositely charged τ leptons or a bb‾ pair. The Z boson is identified via its decays to electrons or muons. The search exploits data collected by the CMS experiment at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.8 fb −1 . No significant deviations are observed from the standard model expectation and limits are set on production cross sections and parameters of two-Higgs-doublet models

Measurement of the azimuthal anisotropy of Y(1S) and Y(2S) mesons in PbPb collisions at √S^{S}NN = 5.02 TeV

The second-order Fourier coefficients (υ$_{2}$) characterizing the azimuthal distributions of Υ(1S) and Υ(2S) mesons produced in PbPb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV are studied. The Υmesons are reconstructed in their dimuon decay channel, as measured by the CMS detector. The collected data set corresponds to an integrated luminosity of 1.7 nb$^{-1}$. The scalar product method is used to extract the υ$_{2}$ coefficients of the azimuthal distributions. Results are reported for the rapidity range |y| < 2.4, in the transverse momentum interval 0 < p$_{T}$ < 50 GeV/c, and in three centrality ranges of 10–30%, 30–50% and 50–90%. In contrast to the J/ψ mesons, the measured υ$_{2}$ values for the Υ mesons are found to be consistent with zero

Search for a low-mass pseudoscalar Higgs boson produced in association with a bb⁻ pair in pp collisions at √s=8 TeV

A search is reported for a light pseudoscalar Higgs boson decaying to a pair of tau leptons, produced in association with a b (b) over bar pair, in the context of two-Higgs-doublet models. The results are based on pp collision data at a centre-of-mass energy of 8 TeV collected by the CMS experiment at the LHC and corresponding to an integrated luminosity of 19.7 fb(-1). Pseudoscalar boson masses between 25 and 80 GeV are probed. No evidence for a pseudoscalar boson is found and upper limits are set on the product of cross section and branching fraction to tau pairs between 7 and 39 pb at the 95% confidence level. This excludes pseudoscalar A bosons with masses between 25 and 80 GeV, with SM-like Higgs boson negative couplings to down-type fermions, produced in association with bb pairs, in Type II, two-Higgs-doublet models.
