Hunyadi, A., Murányi, D. and Páll-Gergely, B., 08 August 2016. Remarks In the original description, Hwang (2014) mentioned three differences between Indian B. plicidens and the subspecies Bensonella plicidens lakainguta. The most important of them was the submarginal elevations of columellar, basal and palatal barriers, i.e. anterior to the hooks those barriers become more elevated. However, this trait can also be seen in Indian B. hooki sp. nov. (Figure 9 (c,d)); see differences between B. lakainguta and B. hooki sp. nov. outlined under the description of the latter. Boysidia (Bensonella) qingliangfengensis (Figure 7 (e,f)) was described from the border region of the Chinese Anhui and Zhejiang Provinces (very close to Pilsbry̾s (1917) record from Hangzhou), and is claimed to be larger than B . plicidens, yet looks identical for all other characters. Therefore, it is treated here as a junior synonym of B . lakainguta Hwang, 2014. Maassen (1999) mentioned that he compared Bensonella karoensis with Japanese shells of Bensonella plicidens (= Bensonella lakainguta). Furthermore, he erroneously stated that Bensonella plicidens inhabited Thailand.Published as part of Páll-Gergely, Barna & White, Tom S., 2023, Solving the mystery of the misunderstood Bensonella plicidens (Benson, 1849) (Gastropoda: Stylommatophora: Hypselostomatidae), pp. 2011-2029 in Journal of Natural History 56 (45 - 48) on pages 2025-2026, DOI: 10.1080/00222933.2022.2152750, http://zenodo.org/record/756093
Modeling and biokinetics in anaerobic acidogenesis of starch-processing wastewater to acetic acid
No full textStarch-processing wastewater was anaerobically treated to produce acetic acid in laboratory-scale, continuously stirred tank reactors. The optimal conditions, in which the maximum acetic acid production occurred, were 0.56 d hydraulic retention time, pH 5.9, and 36.1 degreesC. Acetic acid production at the optimum conditions was 672 +/- 20 mg total organic carbon(equivalent) L-1, which indicated a 75% conversion efficiency of influent total organic carbon into acetic acid. A fourth order Runge-Kutta approximation was used to determine the Monod kinetics of the acidogens by using unsteady-state data from continuous unsteady-state experiments at the optimum conditions. The model outputs and experimental data fit together satisfactorily, suggesting that the unsteady-state approach was appropriate for the evaluation of acidogenic biokinetics. These included mu(m), K-s, Y, and k(d), which were evaluated as being 0.13 h(-1), 25 mg total carbohydrate (TC) L-1, 0.38 mg volatile suspended solid mg(-1) TC, and 0.002 h(-1), respectively.X1144sciescopu
Deletion of vitamin D receptor leads to premature emphysema/COPD by increased matrix metalloproteinases and lymphoid aggregates formation
No full textDeficiency of vitamin D is associated with accelerated decline in lung function. Vitamin D is a ligand for nuclear hormone vitamin D receptor (VDR), and upon binding it modulates various cellular functions. The level of VDR is reduced in lungs of patients with chronic obstructive pulmonary disease (COPD) which led us to hypothesize that deficiency of VDR leads to significant alterations in lung phenotype that are characteristics of COPD/emphysema associated with increased inflammatory response. We found that VDR knock-out (VDR(-/-)) mice had increased influx of inflammatory cells, phospho-acetylation of nuclear factor-kappaB (NF-κB) associated with increased proinflammatory mediators, and up-regulation of matrix metalloproteinases (MMPs) MMP-2, MMP-9, and MMP-12 in the lung. This was associated with emphysema and decline in lung function associated with lymphoid aggregates formation compared to WT mice. These findings suggest that deficiency of VDR in mouse lung can lead to an early onset of emphysema/COPD because of chronic inflammation, immune dysregulation, and lung destruction
Reverse-Link Performance of Synchronous Cellular DS-CDMA Networks in Dispersive Rician Multipath Fading Channels
No full textIn this paper, the reverse-link performance of synchronous DS-CDMA cellular networks is investigated in Rician multipath fading environments. The system’s performance is evaluated in terms of the achievable average bit error rate (BER) and the user capacities of two different network layouts, namely those of a uniform grid of hexagonal multiple cells and a single isolated cell. In the multiple-cell scenario, the impact of the other cells’ interference on the attainable capacity of the synchronous DS-CDMA uplink in investigated. Upon comparing both networks to a conventional asynchronous CDMA system, we demonstrate an achievable user capacity gain of 25% to 56% for synchronous uplink transmission scenario at BER =10-3
Prompt charm production in pp collisions at √<span style="text-decoration:overline">s</span>=7 TeV
No full textCharm production at the LHC in pp collisions at s√=7 TeV is studied with the LHCb detector. The decays D0→K−π+, D+→K−π+π+, D⁎+→D0(K−π+)π+, D+s→ϕ(K−K+)π+, Λ+c→pK−π+, and their charge conjugates are analysed in a data set corresponding to an integrated luminosity of 15 nb−1. Differential cross-sections dσ/dpT are measured for prompt production of the five charmed hadron species in bins of transverse momentum and rapidity in the region 0<pT<8 GeV/c and 2.0<y<4.5. Theoretical predictions are compared to the measured differential cross-sections. The integrated cross-sections of the charm hadrons are computed in the above pT-y range, and their ratios are reported. A combination of the five integrated cross-section measurements gives
σ(cc¯)pT<8 GeV/c,2.0<y<4.5=1419±12(stat)±116(syst)±65(frag) μb,
where the uncertainties are statistical, systematic, and due to the fragmentation functions
Measurements of the absolute branching fractions for D-s(+) -> eta e(+)nu(e) and D-s(+) -> eta ' e(+)nu(e)
No full textBy analyzing 482 pb(-1) of e(+)e(-) collision data collected at root s = 4.009 GeV with the BESIII detector at the BEPCII collider, we measure the absolute branching fractions for the semileptonic decays D-s(+) -> eta e(+)nu(e) and D-s(+) -> eta ' e(+)nu(e) to be B(D-s(+) -> eta e(+)nu(e)) = (2.30 +/- 0.31 +/- 0.08)% and B(D-s(+) -> eta ' e(+)nu(e)) = (0.93 +/- 0.30 +/- 0.05)%, respectively, and their ratio B(D-s(+) -> eta ' e(+)nu(e)) / B(D-s(+) -> eta ' e(+)nu(e)) = 0.40 +/- 0.14 +/- 0.02, where the first uncertainties are statistical and the second ones are systematic. The results are in good agreement with previous measurements within uncertainties; they can be used to determine the eta-eta' mixing angle and improve upon the D-s(+) semileptonic branching ratio precision
Growth kinetic parameter estimation of Candida rugopelliculosa using a fish manufacturing effluent
No full textA fourth order Runge-Kutta approximation was used to determine the Monod kinetics of Candida rugopelliculosa by using unsteady state data from only one continuous unsteady state operation at a fixed dilution rate. The maximum microbial growth rates, mumax, and half saturation coefficient, K-s, were 0.82 +/- 0.22 h(-1) and 690 +/- 220 mg soluble chemical oxygen demand (SCOD) l(-1), respectively. The microbial yield coefficient, Y, and microbial decay rate coefficient, k(d), were 1.39 +/- 0.22 x 10(4) cells mg(-1) SCOD and 0.06 +/- 0.01 h(-1), respectively.X113sciescopu
Measurement of D-0, D+, D+* and D-s(+) production in pp collisions at root s=5.02 TeV with ALICE
No full textThe measurements of the production of prompt D0 , D+ , D∗+ , and D+s mesons in proton–proton (pp) col- lisions at √s = 5.02 TeV with the ALICE detector at the Large Hadron Collider (LHC) are reported. D mesons were reconstructed at mid-rapidity (|y| < 0.5) via their hadronic decay channels D0 → K−π+, D+ → K−π+π+, D∗+ → D0π+ → K−π+π+, D+s → φπ+ → K+K−π+, and their charge conjugates. The production cross sections were measured in the transverse momentum interval 0 < pT < 36GeV/cforD0,1 < pT < 36GeV/cforD+ and D∗+, and in 2 < pT < 24 GeV/c for D+s mesons. Thanks to the higher integrated luminosity, an analysis in finer pT bins with respect to the previous measurements at √s = 7 TeV was performed, allowing for a more detailed description of the cross-section pT shape. The measured pT- differential production cross sections are compared to the results at √s = 7 TeV and to four different perturbative QCD calculations. Its rapidity dependence is also tested combin- ing the ALICE and LHCb measurements in pp collisions at √s = 5.02 TeV. This measurement will allow for a more accurate determination of the nuclear modification factor in p–Pb and Pb–Pb collisions performed at the same nucleon– nucleon centre-of-mass energy
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
