Abstract
We present the mid-infrared (MIR) light curves (LCs) of a tidal disruption event candidate in the center of a nearby ultraluminous infrared galaxy F01004−2237 using archival WISE and NEOWISE data from 2010 to 2016. At the peak of the optical flare, F01004−2237 was IR quiescent. About three years later, its MIR fluxes have shown a steady increase, rising by 1.34 and 1.04 mag in 3.4 and 4.6 μm up to the end of 2016. The host-subtracted MIR peak luminosity is 2–3 × 1044 erg s−1. We interpret the MIR LCs as an infrared echo, i.e., dust reprocessed emission of the optical flare. Fitting the MIR LCs using our dust model, we infer a dust torus of the size of a few parsecs at some inclined angle. The derived dust temperatures range from 590–850 K, and the warm dust mass is ∼7 M
⊙. Such a large mass implies that the dust cannot be newly formed. We also derive the UV luminosity of 4–11 × 1044 erg s−1. The inferred total IR energy is 1–2 × 1052 erg, suggesting a large dust covering factor. Finally, our dust model suggests that the long tail of the optical flare could be due to dust scattering.
Possibilités, conditions et limites d’un management subsidiaire : le cas d’une Banque Régionale
Authors: Merceron Jean-Luc 
Published: May 2017

Il n’y a pas de « bien être » sans « bien faire » (Clot, 2010). La question du « travail bien fait » mobilise chacun d’entre nous dans son activité quotidienne. Cependant, qu’est-ce que le travail bien fait ? De quelles ressources avons-nous besoin pour bien faire notre travail ? Qu’est-ce qui empêche le travail bien fait ? Ces questions fondamentales pour le bon fonctionnement d’une entreprise et la santé au travail méritent de mobiliser l’ensemble des travailleurs de la ligne hiérarchique afin de contribuer à un ajustement permanent et pertinent entre « fiabilité réglée » et « fiabilité gérée » (Petit, Dugué, Daniellou, 2011). Dans un contexte contemporain de diminution du « pouvoir d’agir » des individus au travail (Clot, 2008, 2010), une vieille notion de philosophie politique, la subsidiarité, fait un retour remarquable dans la recherche en sciences sociales : en ergonomie (Petit, Dugué, Daniellou, 2011), en droit (Barroche, 2012), en économie (Gomez, 2011), en gestion (Detchessahar, 2013 ; Melé 2005), parce que la subsidiarité envisage l’organisation par le bas en ayant le souci majeur de préserver l’agir créatif des individus et l’ambition permanente de placer la décision au plus près de l’action. Mais un management subsidiaire est-il envisageable concrètement ? Dans ce cas, quelles sont ses conditions de mise en œuvre, et ses limites. Dans le cadre d’une recherche-intervention au sein d’une Banque Régionale, nous testons l’hypothèse suivante : la mise en place, dans les routines managériales, d’espaces de discussion sur le travail bien fait, permet d’alimenter un management subsidiaire qui concilie santé au travail et performance organisationnelle.

Abstract. This study was carried out to screen the GDF9 gene and evaluate the polymorphism effect on litter size of four Iranian sheep breeds using the PCR-RFLP and PCR-SSCP methods. First, sequencing of the GDF9 gene in 16 twin-birth, 4 triplet-birth, and 2 infertile ewes showed that, in addition to G2, G3, G4, G5, and G6 mutations that have been previously reported in other breeds, a new G0 mutation, called C25T, exists in the GDF9 sequence of 1 out of 22 ewes and causes L9F substitution in the signal peptide region. None of the triplet-birth or infertile ewes carried G1, G4, G7, FecGE, G8, or FecGT mutations. In the second experiment, a large dataset was used: 605 individuals including 496 ewes (145 Afshari, 54 Shal, 126 Ghezel, and 171 Lori-Bakhtyari sheep), and 109 rams (26 Afshari, 23 Shal, 10 Ghezel, and 50 Lori-Bakhtyari sheep. There were no sheep carrying the G7, G8, or Thoka mutations. Among all 109 rams that were used in this study, none of them were homozygous for the G1 mutation. Moreover, abundance of heterozygote rams (G1/G+) varied from 0.0 (Afshari) to 28.6 % (Lori-Bakhtyari and Ghezel). The highest and the lowest frequencies of the G4 mutation were 30.6 and 3.0 % in Shal and Afshari breeds, respectively. Moreover, G4 abundance varied from 0.0 to 42.3 %, from 3.0 to 26.9, and from 3.0 to 30.6 % in rams, ewes, and overall, respectively. There was a significant difference in the abundance of G1 and G4 mutations between breeds. However, neither the G1 nor the G4 mutation was associated with litter size in Afshari, Ghezel, Lori-Bakhtyari, or Shal sheep breeds. In conclusion, the results of this study showed that GDF9 G1 and G4 mutations are not the reason for higher litter size in Iranian sheep. Moreover, the GDF9 G0 and G6 mutations do not cause triplet births or infertility in Iranian ewes. Therefore, it is unlikely that variant GDF9 mRNA induces larger litter size or infertility in Iranian ewes.

Abstract. The Shark and Harney rivers, located on the southwest coast of Florida, USA, originate in the freshwater, karstic marshes of the Everglades and flow through the largest contiguous mangrove forest in North America. In November 2010 and 2011, dissolved carbon source–sink dynamics was examined in these rivers during SF6 tracer release experiments. Approximately 80 % of the total dissolved carbon flux out of the Shark and Harney rivers during these experiments was in the form of inorganic carbon, either via air–water CO2 exchange or longitudinal flux of dissolved inorganic carbon (DIC) to the coastal ocean. Between 42 and 48 % of the total mangrove-derived DIC flux into the rivers was emitted to the atmosphere, with the remaining being discharged to the coastal ocean. Dissolved organic carbon (DOC) represented ca. 10 % of the total mangrove-derived dissolved carbon flux from the forests to the rivers. The sum of mangrove-derived DIC and DOC export from the forest to these rivers was estimated to be at least 18.9 to 24.5 mmol m−2 d−1, a rate lower than other independent estimates from Shark River and from other mangrove forests. Results from these experiments also suggest that in Shark and Harney rivers, mangrove contribution to the estuarine flux of dissolved carbon to the ocean is less than 10 %.

Abstract. The Global Land Evaporation Amsterdam Model (GLEAM) is a set of algorithms dedicated to the estimation of terrestrial evaporation and root-zone soil moisture from satellite data. Ever since its development in 2011, the model has been regularly revised, aiming at the optimal incorporation of new satellite-observed geophysical variables, and improving the representation of physical processes. In this study, the next version of this model (v3) is presented. Key changes relative to the previous version include (1) a revised formulation of the evaporative stress, (2) an optimized drainage algorithm, and (3) a new soil moisture data assimilation system. GLEAM v3 is used to produce three new data sets of terrestrial evaporation and root-zone soil moisture, including a 36-year data set spanning 1980–2015, referred to as v3a (based on satellite-observed soil moisture, vegetation optical depth and snow-water equivalent, reanalysis air temperature and radiation, and a multi-source precipitation product), and two satellite-based data sets. The latter share most of their forcing, except for the vegetation optical depth and soil moisture, which are based on observations from different passive and active C- and L-band microwave sensors (European Space Agency Climate Change Initiative, ESA CCI) for the v3b data set (spanning 2003–2015) and observations from the Soil Moisture and Ocean Salinity (SMOS) satellite in the v3c data set (spanning 2011–2015). Here, these three data sets are described in detail, compared against analogous data sets generated using the previous version of GLEAM (v2), and validated against measurements from 91 eddy-covariance towers and 2325 soil moisture sensors across a broad range of ecosystems. Results indicate that the quality of the v3 soil moisture is consistently better than the one from v2: average correlations against in situ surface soil moisture measurements increase from 0.61 to 0.64 in the case of the v3a data set and the representation of soil moisture in the second layer improves as well, with correlations increasing from 0.47 to 0.53. Similar improvements are observed for the v3b and c data sets. Despite regional differences, the quality of the evaporation fluxes remains overall similar to the one obtained using the previous version of GLEAM, with average correlations against eddy-covariance measurements ranging between 0.78 and 0.81 for the different data sets. These global data sets of terrestrial evaporation and root-zone soil moisture are now openly available at www.GLEAM.eu and may be used for large-scale hydrological applications, climate studies, or research on land–atmosphere feedbacks.

Published: May 2017

This paper was focused on the determination of the inhibitory effect of selected essential oils on growth of ten isolates of Aspergillus flavus and their potential ability to produce mycotoxins in vitro by TLC method. The isolates were obtained from moldy bread of domestic origin. We followed the impact of five essential oils at 100% concentration - lemon, eucalyptus, oregano, sage and thyme. The effect of the essential oils we tested the gaseous diffusion method. We isolates grown on CYA (Czapek yeast extract agar), in the dark at 25 ±1 °C, 14 days. The diameter of colonies grown we continuously measured on the 3rd, 7th, 11th, and 14th day of cultivation. The results of the paper suggest that oregano and thyme essential oil had 100% inhibited the growth of all tested isolates of Aspergillus flavus. Lemon, eucalyptus and sage essential oil had not significant inhibitory effects on tested isolates Aspergillus flavus, but affected the growth of colonies throughout the cultivation. In addition to the inhibitory effect we witnessed the stimulative effect of lemon, eucalyptus and sage essential oil to some isolates. Together with the antifungal effect of essential oils, we monitored the ability of Aspergillus flavus isolates to produce mycotoxins - aflatoxin B1 (AFB1) and cyclopiazonic acid (CPA) in the presence of essential oils. Production mycotoxins we have seen in the last (14th) day of cultivation. Lemon and eucalyptus essential oil did not affect the production of mycotoxins. In the case of sage essential oil we were recorded cyclopiazonic acid production in three of the ten isolates from the all three repetitions, while neither isolate did not produced aflatoxin B1. The production of secondary metabolites was detected in all control samples. From the results we can say that oregano and thyme essential oil could be used as a natural preservative useful in the food industry.

Biogenic amines are indispensable components of living cells; nevertheless these compounds could be toxic for human health in higher concentrations. Putrescine is supposed to be the major biogenic amine associated with microbial food spoilage. Development of reliable, fast and culture-independent molecular methods to detect bacteria producing biogenic amines deserves the attention, especially of the food industry in purpose to protect health. The objective of this study was to verify the newly designed primer sets for detection of two inducible genes adiA and speF together in Salmonella enterica and Escherichia coli genome by Real-time PCR. These forenamed genes encode enzymes in the metabolic pathway which leads to production of putrescine in Gram-negative bacteria. Moreover, relative expression of these genes was studied in E. coli CCM 3954 strain using Real-time PCR. In this study, sets of new primers for the detection two inducible genes (speF and adiA) in Salmonella enterica and E. coli by Real-time PCR were designed and tested. Amplification efficiency of a Real-time PCR was calculated from the slope of the standard curves (adiA, speF, gapA). An efficiency in a range from 95 to 105 % for all tested reactions was achieved. The gene expression (R) of adiA and speF genes in E. coli was varied depending on culture conditions. The highest gene expression of adiA and speF was observed at 6, 24 and 36 h (RadiA ~ 3, 5, 9; RspeF ~11, 10, 9; respectively) after initiation of growth of this bacteria in nutrient broth medium enchired with amino acids. The results show that these primers could be used for relative quantification analysis of E. coli.

Published: May 2017

The article presents the influence assessment of significance of some selected variables from the entrepreneurs' accounting system on the achieved profit or loss of the agricultural companies in the Slovak Republic. Accounting information serves as an active tool for internal users for operational as well as strategic company management, and for external users the information is determined as legally binding output information which is a subject to disclosure. Individual financial statements of assessed agricultural companies are considered to be the relevant source of information. Agricultural companies are represented by commercial companies and agricultural cooperatives. Profit or loss after income tax presents the final complex effect of economic company's performance. The existence and development of companies is conditioned by assets which amount and structure depend on focus and the range of subject activity but as well as on specific factors set by the production process in the agricultural primary production. The increase in liabilities is notable by the influence of unsufficient amount of own company funding sources, mainly the increase in trade payables. The continuance of company reproduction process is secured by a bank loan drawdown. The income situation of companies of agricultural primary production is favourably influenced by the subsidies of non-investment character. During the observed period of years 2004 - 2014 the examined variables were assessed by means of statistical methods. The obtained results of rate determination of statistical correlation between selected variables by means of classical canonical analysis and non-parametric correlation analysis secured that in the assessed group of companies all analysed variables influenced statistically significantly profit or loss after income tax, mainly the total value of assets and non-investment subsidies, except for years 2010, 2012 a 2013, when the statistically insignificant correlations was determined between profit or loss and especially short-term trade payables and current bank loans. As regards the existence point of view it is recommended to companies to maintain the optimal assets and capital structure as well as the achievement of suitable profitability of company's activity. Only the complex attitude towards the subject issue can be the assumption of sustainability for companies of agricultural primary production in the Slovak Republic and the increase in their performance.
The Emergency Manager: Strategic Racism, Technocracy, and the Poisoning of Flint's Children
Authors: Stanley Jason 
Published: May 2017

Abstract
In April 2014, the city of Flint, Michigan, began using water from the Flint River. The official reason to break Flint's long time contract with the Detroit Water and Sewage Department was financial efficiency; it was presented as a cost-cutting measure. Flint residents began immediately complaining about their water, complaints that were ignored. Thanks to the local activists, it was eventually discovered that the water was indeed corrosive, the city failed to treat it, and lead leached from the pipes into the water drunk by the city's children and families. By September 2015, the city was acknowledging the size of the health crisis this entailed, and in October 2015, Flint switched back to Detroit water. It was too late: the damage was done, and Flint's children have shown persistently high levels of lead—poisoned by a series of decisions that would never have been made in a majority white city. It is also now clear that relevant officials knew that the switch to the Flint River was in fact more expensive, both in the short term and the long term, than remaining with the Detroit Water and Sewage Department. Using Vesla Weaver's concept of frontlash, I argue that a technocratic ideology combined with a certain version of racism, resembling settler colonialism, is the cause of the tragedy.

“Mis pinturas reflejan parte de mi entorno, lo que veo, lo que toco, lo simple, lo complicado, muchas veces lo extraño para mí, son cosas que todos ya conocemos, pero las plasmo con un lenguaje particular. Plátanos, frutas, máquinas y paisajes son los temas que pueden ver en mis obras. Esto de ser pintor no ha sido fácil, se requiere paciencia y perseverancia, pero el placer que me da pintar ni con todo el oro del mundo lo podría pagar, es como una adicción que cuando empiezo a dar las primeras pinceladas me doy cuenta que ya no puedo parar. He pasado muchas horas frente a un lienzo y sé que cada minuto que pasa es menos tiempo de mi vida. El tiempo tampoco tiene precio, pero si lo gasto pintando, ha valido la pena vivir, no me arrepiento de nada, es apenas el comienzo, tengo muchas metas que seguir y creo ir por el rumbo correcto, agradezco a la vida por esta oportunidad”.Marcelo AmpiéArtista plástico nicaragüense(Palabras ofrecidas en su primera exposición personal, julio 2016).
An Addendum on Postoptimality of Maximally Reliable Path
Authors: Hosseini Ahmad , Kabir Baiki Bita 
Published: May 2017

This paper studies one aspect of the robustness of optimal solutions to the \textit{maximally reliable path} and investigates the infimum and supremum multiplicative perturbations each individual arc can tolerate preserving the optimality of a given optimal path. When such marginal values are to be determined simultaneously for all arcs in a network, considerable duplication of effort can be avoided through the use of our proposed approach.

AbstractIntroduction: The diagnostic procedure for chronic hepatitis C infection (CHC) usually combines anti‐HCV antibody (HCV‐Ab) and HCV‐RNA measurement. Quantifying HCV core antigen (cAg) as a one‐step procedure could shorten the diagnostic process. We aimed to assess the performance of cAg quantification in diagnosing CHC and how it is influenced by concomitant HIV or HBV infections.Methods: The cAg was quantified by an automated assay (Abbott Diagnostics) in 465 HCV‐Abnegative serum samples and 544 HCV‐RNA positive serum samples (n = 1009) collected in patients from the Pasteur Center in Cameroon, some of whom were infected by HBV or HIV. Its performance was evaluated in comparison to the gold standard (ELISA or PCR) by estimating its sensitivity (Se) and specificity (Sp), and by comparing the area under ROC (AUROC) curves in each patient population: HCV mono‐infected, HCV‐HBV and HIV‐HCV co‐infected.Results: Among the 465 HCV‐Abnegative patients, 51 and 79 were HIV‐ and HBV‐infected, respectively, whereas among the 544 patients with CHC, 27 and 28 were HIV‐ and HBV‐infected, respectively. The Spearmanρcorrelation coefficient between cAg and HCV‐RNA was 0.75 (p < 0.00001). The assay had a sensitivity of 95.7% (95% CI: 93.2–97.5) and a specificity of 99.7% (95% CI: 98.1–10) in diagnosing CHC, corresponding to an AUROC of 0.99 (95% CI: 0.98–1.0). Being HIV‐ or HBV‐infected did not impact the performance of cAg (Se = 96.4%, Sp = 96.2% and AUROC = 0.98 (95% CI: 0.95–1.0) in the HBV group, Se = 100%, Sp = 88.2% and AUROC = 0.99 (95% CI: 0.97–1.0) in the HIV group,pbetween AUROC = 0.69).Conclusions: The cAg quantification displayed a high specificity and sensitivity for the diagnosis of CHC in Cameroon, and its performance was not significantly modified by a concomitant HIV or HBV infection. In the context of CHC elimination on a global scale, using cAg quantification as a screening tool to directly identify CHC could be a reliable tool in a “test and treat” strategy.
