Abstract
This study aimed at developing a simple tool for improving the management of gaseous emissions in UASB-based sewage treatment plants (STPs), considering different scenarios for the management of sludge, biogas and gaseous emissions (especially sulfide and methane). For small STPs (&lt;10,000 inhab.), simple alternatives for the use of biogas were considered (e.g. for excess sludge hygienization and household usages). For medium- (&gt;10,000; &lt;100,000) and large-scale (&gt;100,000 inhab.) STPs, other biogas uses were considered, such as in sludge dryers, boilers or combined heat and power engines for electricity generation and heat recovery. All these possibilities were grouped in an interactive spreadsheet containing an extensive database of factors that affect gaseous emissions and energy balance in STPs. The tool can be important for decision makers choosing the best gaseous emissions management practices in UASB-based STPs. Carbon footprint should be the main decision factor when evaluating alternatives for the management of gaseous emissions.

Abstract
Service quality and customer satisfaction are very important concepts that water enterprises must understand and measure from the customers' perspective to satisfy their needs. The main objectives of this research were to assess the level of customer satisfaction on urban water supply services of Southern Region, Ethiopia, and identify major determinants. Quantitative data were collected from 8,413 customers in seventeen towns, using a questionnaire based on the SERVQUAL model. Qualitative data were collected from customers via focus group discussion, and interviews were used with utility employees and officials. The results showed 47% of customers were satisfied with the water supply enterprise services, while 43% were dissatisfied for various reasons. The customer satisfaction score was below the acceptable level for all service quality dimensions, and understanding of customers, communication, and responsiveness were far below the benchmark. The correlation analysis revealed the existence of a monotonic, positive relationship between customers' total satisfaction and service quality dimensions. The proportional odds model indicated that total customer satisfaction was highly dependent on the nine service quality dimensions used in this research.

Abstract
Activated carbons were prepared from sewage sludge by chemical activation with pyrolusite (PAC) to develop an efficient adsorbent for phosphate removal from aqueous solution. One percent (wt.) pyrolusite addition was proved to have an important effect on pore formation of the produced carbon. PAC showed 17.06% larger Brunauer–Emmett–Teller (BET) surface area than the sewage sludge-based activated carbon without modification (SAC). The adsorption results showed that the phosphate removal by PAC was 13% higher than SAC's. The adsorption experiments also showed that PAC had very good performance with high phosphate removal rate (ca. 90%) in a wide pH range (pH = 4–8), and could be stable after 30 min reaction. Adsorption isotherm and kinetics studies demonstrated that phosphate adsorption onto the modified adsorbent was well fitted by the Langmuir isotherm and could be described by the pseudo-second-order kinetic model. The modified sewage sludge-based activated carbons were effective and alternative adsorbents for the removal of phosphorus from aqueous solution due to their considerable adsorptive capacities and the low-cost renewable sources.
Plant-Made Antibodies: Properties and Therapeutic Applications
Authors: Komarova Tatiana V. , Sheshukova Ekaterina V. , Dorokhov Yuri L. 
Published: December 2017

Background:A cost-effective plant platform for therapeutic monoclonal antibody production is both flexible and scalable. Plant cells have mechanisms for protein synthesis and posttranslational modification, including glycosylation, similar to those in animal cells. However, plants produce less complex and diverse Asn-attached glycans compared to animal cells and contain plant-specific residues. Nevertheless, plant-made antibodies (PMAbs) could be advantageous compared to those produced in animal cells due to the absence of a risk of contamination from nucleic acids or proteins of animal origin.Objective:In this review, the various platforms of PMAbs production are described, and the widely used transient expression system based on Agrobacterium-mediated delivery of genetic material into plant cells is discussed in detail.Results:We examined the features of and approaches to humanizing the Asn-linked glycan of PMAbs. The prospects for PMAbs in the prevention and treatment of human infectious diseases have been illustrated by promising results with PMAbs against human immunodeficiency virus, rotavirus infection, human respiratory syncytial virus, rabies, anthrax and Ebola virus. The pre-clinical and clinical trials of PMAbs against different types of cancer, including lymphoma and breast cancer, are addressed.Conclusion:PMAb biosafety assessments in patients suggest that it has no side effects, although this does not completely remove concerns about the potential immunogenicity of some plant glycans in humans. Several PMAbs at various developmental stages have been proposed. Promise for the clinical use of PMAbs is aimed at the treatment of viral and bacterial infections as well as in anti-cancer treatment.

Mastitis is udder inflammation that can be caused by the entry of pathogenic bacteria through the teat. One of the treatments that can prevent bacteria infection is teat dipping. This research was aimed to identify the effectof teat dipping after milking to the presence of pathogenic bacteria that cause subclinical mastitis (Staphylococcus aureus, Streptococcus agalactiae, and Escherichia coli) and the presence of pathogenic bacteria that cause subclinicalmastitis by quarter of udder. Milk samples were taken from normal lactation period of dairy cows, clinically healthy, and positive subclinical mastitis status when the intervention was applied. Sixty seven samples of quarters from 18dairy cows were identified to the presence of pathogenic bacteria that cause subclinical mastitis before teat dipping and at 1st, 2nd, and 3rd months after teat dipping. Identification of the presence of pathogenic bacteria was done byculturing samples on selective agar media. The presence of common pathogenic bacteria, Staphylococcus aureus, and Escherichia coli decreased significantly after teat dipping, while Streptococcus agalactiae and other pathogenicbacteria did not decrease significantly. The presence of pathogenic bacteria based on the quarter of udder did not show the significance difference. Application of teat dipping after milking was able to decrease the presence ofpathogenic bacteria that cause subclinical mastitis.
Cost–effectiveness analysis of treatments involving radioembolization in intermediate-stage hepatocellular carcinoma
Authors: Rognoni Carla , Ciani Oriana , Sommariva Silvia , Tarricone Rosanna 
Published: December 2017

Aim:
We evaluated two treatment sequences, transarterial radioembolization followed by transarterial chemoembolization and possibly sorafenib (=TTS) versus transarterial radioembolization followed by sorafenib alone (=TS), to identify the most cost-effective pathway to treat intermediate-stage hepatocellular carcinoma from the Italian healthcare system perspective.
Materials & methods:
A Markov model was developed to project costs and health outcomes for TTS and TS over a lifetime horizon. Data available at three hospitals in Italy were collected. Healthcare resource utilization was derived from standard clinical protocols. Costs were obtained from official regional tariffs.
Results & Conclusion:
Taking into consideration 16 patients for TTS and 22 patients for TS pathways, the TTS sequence provided a dominant strategy in comparison to TS. Further evidence is desirable to confirm these results.

Published: December 2017

Background: Physical activity (PA) plays a major role in maintaining cognition in older adults. PA has been shown to be correlated with total hippocampal volume, a memory-critical region within the medial temporal lobe (MTL). However, research on associations between PA and MTL sub-region integrity is limited. Objective: To examine the relationship between PA, MTL thickness, and its sub-regions, and cognitive function in non-demented older adults with memory complaints. Methods: Twenty-nine subjects aged ≥60 years, with memory complaints were recruited for this cross-sectional study. PA was tracked for 7 days using accelerometers, and average number of steps/day determined. Subjects were categorized into two groups: those who walked ≤4000 steps/day (lower PA) and those with >4000 steps/day (higher PA). Subjects received neuropsychological testing and 3T MRI scans. Nonparametric ANCOVAs controlling for age examined differences between the two groups. Results: Twenty-six subjects aged 72.7(8.1) years completed the study. The higher PA group ( n = 13) had thicker fusiform gyrus (median difference = 0.11 mm, effect size (ES) = 1.43, p = 0.001) and parahippocampal cortex (median difference = 0.12 mm, ES = 0.93, p = 0.04) compared to the lower PA group. The higher PA group also exhibited superior performance in attention and information-processing speed (median difference = 0.90, ES = 1.61, p = 0.003) and executive functioning (median difference = 0.97, ES = 1.24, p = 0.05). Memory recall was not significantly different between the two groups. Conclusion: Older non-demented individuals complaining of memory loss who walked >4000 steps each day had thicker MTL sub-regions and better cognitive functioning than those who walked ≤4000 steps. Future studies should include longitudinal analyses and explore mechanisms mediating hippocampal related atrophy.
Spin–Orbit Misalignment and Precession in the Kepler-13Ab Planetary System

Published: December 2017

Abstract
Gravity darkening induced by rapid stellar rotation provides us with a unique opportunity to characterize the spin–orbit misalignment of a planetary system through analysis of its photometric transit. We use the gravity-darkened transit modeling code simuTrans to reproduce the transit light curve of Kepler-13Ab by separately analyzing phase-folded transits for 12 short-cadence Kepler quarters. We verify the temporal change in impact parameter indicative of spin–orbit precession identified by Szabó et al. and Masuda, reporting a rate of change

day−1. We further investigate the effect of light dilution on the fitted impact parameter and find that less than 1% of additional light is sufficient to explain the seasonal variation seen in the Kepler quarter data. We then extend our precession analysis to the phase curve data from which we report a rate of change

day−1. This value is consistent with that of the transit data at a lower significance and provides the first evidence of spin–orbit precession based solely on the temporal variation of the secondary eclipse.
Gemini Spectra of Star Clusters in the Spiral Galaxy M101

Published: December 2017

Abstract
We present low resolution, visible light spectra of 41 star clusters in the spiral galaxy M101, taken with the Gemini/GMOS instrument. We measure Lick indices for each cluster and compare with BaSTI models to estimate their ages and metallicities. We also measure the line-of-sight velocities. We find that 25 of the clusters are fairly young massive clusters (YMCs) with ages of hundreds of millions of years, and 16 appear to be older, globular clusters (GCs). There are at least four GCs with best-fit ages of ≈1–3 Gyr and eight with best-fit ages of ≈5–10 Gyr. The mean metallicity of the YMCs is [Fe/H] ≈ −0.1 and for the GCs is [Fe/H] ≈ −0.9. We find a near-continuous spread in both age and metallicity for our sample, which may indicate that M101 had a more-or-less continuous history of cluster and star formation. From the kinematics, we find that the YMCs rotate with the H i gas fairly well, while the GCs do not. We cannot definitively say whether the GCs sampled here lie in an inner halo, thick disk, or bulge/psuedobulge component, although given the very small bulge in M101, the last seems unlikely. The kinematics and ages of the YMCs suggest that M101 may have undergone heating of its disk or possibly a continuous merger/accretion history for the galaxy.
Correlated Signatures of Gravitational-wave and Neutrino Emission in Three-dimensional General-relativistic Core-collapse Supernova Simulations
Authors: Kuroda Takami , Kotake Kei , Hayama Kazuhiro , Takiwaki Tomoya 
Published: December 2017

Abstract
We present results from general-relativistic (GR) three-dimensional (3D) core-collapse simulations with approximate neutrino transport for three nonrotating progenitors (11.2, 15, and 40 M
⊙) using different nuclear equations of state (EOSs). We find that the combination of progenitor’s higher compactness at bounce and the use of softer EOS leads to stronger activity of the standing accretion shock instability (SASI). We confirm previous predications that the SASI produces characteristic time modulations both in neutrino and gravitational-wave (GW) signals. By performing a correlation analysis of the SASI-modulated neutrino and GW signals, we find that the correlation becomes highest when we take into account the time-delay effect due to the advection of material from the neutrino sphere to the proto-neutron star core surface. Our results suggest that the correlation of the neutrino and GW signals, if detected, would provide a new signature of the vigorous SASI activity in the supernova core, which can be hardly seen if neutrino-convection dominates over the SASI.

Published: December 2017

Abstract
Inelastic cross sections and rate coefficients in Ca + H and Ca+ + H− collisions for all transitions between the 17 lowest covalent states plus one ionic molecular state are calculated based on the most recent ab initio adiabatic potentials for the 11 lowest molecular states, as well as on the model asymptotic potentials for higher-lying states, including the ground ionic molecular state. Nuclear dynamics is treated by the probability-current method and the multichannel formulas for the collision energy range 0.01–100 eV. The rates are computed for mutual neutralization, ion-pair formation, and (de-)excitation processes for the temperature range T = 1000–10,000 K. The calculations single out the partial processes with large and moderate rate coefficients. The largest rates correspond to the mutual neutralization into the

Testing the Performance and Accuracy of the relxill Model for the Relativistic X-Ray Reflection from Accretion Disks
Authors: Choudhury Kishalay , García Javier A. , Steiner James F. , Bambi Cosimo 
Published: December 2017

Abstract
The reflection spectroscopic model relxill is commonly implemented in studying relativistic X-ray reflection from accretion disks around black holes. We present a systematic study of the model’s capability to constrain the dimensionless spin and ionization parameters from ∼6000 Nuclear Spectroscopic Telescope Array (NuSTAR) simulations of a bright X-ray source employing the lamp-post geometry. We employ high-count spectra to show the limitations in the model without being confused with limitations in signal-to-noise. We find that both parameters are well-recovered at 90% confidence with improving constraints at higher reflection fraction, high spin, and low source height. We test spectra across a broad range—first at 106–107 and then ∼105 total source counts across the effective 3–79 keV band of NuSTAR, and discover a strong dependence of the results on how fits are performed around the starting parameters, owing to the complexity of the model itself. A blind fit chosen over an approach that carries some estimates of the actual parameter values can lead to significantly worse recovery of model parameters. We further stress the importance to span the space of nonlinear-behaving parameters like

carefully and thoroughly for the model to avoid misleading results. In light of selecting fitting procedures, we recall the necessity to pay attention to the choice of data binning and fit statistics used to test the goodness of fit by demonstrating the effect on the photon index Γ. We re-emphasize and implore the need to account for the detector resolution while binning X-ray data and using Poisson fit statistics instead while analyzing Poissonian data.

Abstract
We present new Hubble Space Telescope (HST) Advanced Camera for Surveys observations and detailed models for a recently discovered edge-on protoplanetary disk around ESO-Hα 569 (a low-mass T Tauri star in the Cha I star-forming region). Using radiative transfer models, we probe the distribution of the grains and overall shape of the disk (inclination, scale height, dust mass, flaring exponent, and surface/volume density exponent) by model fitting to multiwavelength (F606W and F814W) HST observations together with a literature-compiled spectral energy distribution. A new tool set was developed for finding optimal fits of MCFOST radiative transfer models using the MCMC code emcee to efficiently explore the high-dimensional parameter space. It is able to self-consistently and simultaneously fit a wide variety of observables in order to place constraints on the physical properties of a given disk, while also rigorously assessing the uncertainties in those derived properties. We confirm that ESO-Hα 569 is an optically thick nearly edge-on protoplanetary disk. The shape of the disk is well-described by a flared disk model with an exponentially tapered outer edge, consistent with models previously advocated on theoretical grounds and supported by millimeter interferometry. The scattered-light images and spectral energy distribution are best fit by an unusually high total disk mass (gas+dust assuming a ratio of 100:1) with a disk-to-star mass ratio of 0.16.

Abstract
Broad-lined type Ic supernovae (SNe Ic-BL) are a subclass of rare core-collapse SNe whose energy source is debated in the literature. Recently, a series of investigations on SNe Ic-BL with the magnetar (plus 56Ni) model were carried out. Evidence for magnetar formation was found for the well-observed SNe Ic-BL 1998bw and 2002ap. In this paper, we systematically study a large sample of SNe Ic-BL not associated with gamma-ray bursts (GRBs). We use photospheric velocity data determined in a homogeneous way. We find that the magnetar+56Ni model provides a good description of the light curves and velocity evolution of our sample of SNe Ic-BL, although some SNe (not all) can also be described by the pure-magnetar model or by the two-component pure-56Ni model (three out of 12 are unlikely to be explained by two-component model). In the magnetar+56Ni model, the amount of 56Ni required to explain their luminosity is significantly reduced, and the derived initial explosion energy is, in general, in accordance with neutrino heating. Some correlations between different physical parameters are evaluated, and their implications regarding magnetic field amplification and the total energy reservoir are discussed.
La philaletheia come expertise etica dello storico politicamente impegnato. Il caso di Teopompo
Authors: Ottone Gabriella 
Published: December 2017

Résumé La contribution est centrée sur le concept de philaletheia comme catégorie éthique liée au domaine historiographique. Dans le cas de Théopompe, on relève une tendance visant à faire coïncider ce concept avec l’idée d’une recherche historique rigoureuse et approfondie, apanage de l’historien de profession qui, en vertu des compétences acquises à travers l’expérience sur le terrain, peut proposer tout à fait légitimement ses services en tant qu’interlocuteur et conseiller politique. Le thème semble remonter à des contextes de polémique à l’encontre de Platon et d’autres intellectuels – de façon plausible, dans des domaines étroitement liés à la pratique de la communication politique – et recouvre des valeurs tant professionnelles qu’éthiques.
