Published: January 2019

Porous phosphide NixCoyP composite nanomaterials are successfully synthesized at different Ni/Co ratios (=0, 0.5, 1, and 2) to reduce 4-nitrophenol. The X-ray diffraction and X-ray photoelectron spectroscopy results demonstrate that the products are CoP, NiCoP/CoP, NiCoP, and NiCoP/Ni2P when the Ni/Co ratio is 0, 0.5, 1, and 2, respectively. The products exhibit different catalytic performance for reduction of 4-nitrophenol at room temperature. Among them, the pure NiCoP delivers a better catalytic efficiency with k app = 677.4 × 10 − 2 min − 1 and k = 338.7 ( Lg − 1 min − 1 ) , due to the synergy between Ni and Co atoms. The sequence of catalytic efficiency of different samples is CoP < NiCoP/CoP < NiCoP/Ni2P < NiCoP.
Active Asteroid P/2017 S5 (ATLAS)

Published: January 2019

Abstract
Observations of active asteroid P/2017 S5 when near perihelion reveal the ejection of large (102–104
μm) particles at 0.2–2 m s−1 speeds, with estimated mass-loss rates of a few kg s−1. The protracted nature of the mass loss (continuous over ∼150 days) is compatible with a sublimation origin, meaning that this object is likely an ice-bearing main-belt comet. Equilibrium sublimation of exposed water ice covering as little as 0.1 km2 can match the data. Observations a year after perihelion show the object in an inactive state from which we deduce a nucleus effective radius

(albedo 0.06 ± 0.02 assumed). The gravitational escape speed from a body of this size is just ∼0.3 m s−1, comparable to the inferred ejection speed of the dust. Time-series photometry provides tentative evidence for rapid rotation (lightcurve period 1.4 hr) that may also play a role in the loss of mass and which, if real, is a likely consequence of spin-up by sublimation torques. P/2017 S5 shares both physical and orbital similarities with the split active asteroid pair P/2016 J1-A and J1-B, and all three objects are likely members of the ∼7 Myr old, collisionally produced, Theobalda family.

Published: January 2019

Abstract
We present high spatial resolution LBTI/NOMIC 9–12 μm images of VY CMa and its massive outflow feature, the Southwest (SW) Clump. Combined with high-resolution imaging from the Hubble Space Telescope (0.4–1 μm) and LBT/LMIRCam (1–5μm), we isolate the spectral energy distribution (SED) of the clump from the star itself. Using radiative-transfer code DUSTY, we model both the scattered light from VY CMa and the thermal emission from the dust in the clump to estimate the optical depth, mass, and temperature of the SW Clump. The SW Clump is optically thick at 8.9 μm with a brightness temperature of ∼200 K. With a dust chemistry of equal parts silicates and metallic iron, as well as assumptions on grain size distribution, we estimate a dust mass of 5.4 × 10−5
M
⊙. For a gas-to-dust ratio of 100, this implies a total mass of 5.4 × 10−3
M
⊙. Compared to the typical mass-loss rate of VY CMa, the SW Clump represents an extreme, localized mass-loss event from ≲300 yr ago.

Abstract
We report the discovery of 10 transiting extrasolar planets by the HATSouth survey. The planets range in mass from the super-Neptune HATS-62b, with

, to the super-Jupiter HATS-66b, with

, and in size from the Saturn HATS-69b, with

, to the inflated Jupiter HATS-67b, with

. The planets have orbital periods between

days (HATS-67b) and

days (HATS-61b). The hosts are dwarf stars with masses ranging from

(HATS-69) to

(HATS-64) and have apparent magnitudes between

mag (HATS-68) and

mag (HATS-66). The super-Neptune HATS-62b is the least massive planet discovered to date with a radius larger than Jupiter. Based largely on the Gaia DR2 distances and broadband photometry, we identify three systems (HATS-62, HATS-64, and HATS-65) as having possible unresolved binary star companions. We discuss in detail our methods for incorporating the Gaia DR2 observations into our modeling of the system parameters and into our blend analysis procedures.
SI iv Resonance Line Emission during Solar Flares: Non-LTE, Nonequilibrium, Radiation Transfer Simulations
Authors: Kerr Graham S. , Carlsson Mats , Allred Joel C. , Young Peter R. , Daw Adrian N. 
Published: January 2019

Abstract
The Interface Region Imaging Spectrograph routinely observes the Si iv resonance lines. When analyzing quiescent observations of these lines, it has typically been assumed that they form under optically thin conditions. This is likely valid for the quiescent Sun, but this assumption has also been applied to the more extreme flaring scenario. We used 36 electron-beam-driven radiation hydrodynamic solar flare simulations, computed using the RADYN code, to probe the validity of this assumption. Using these simulated atmospheres, we solved the radiation transfer equations to obtain the non-LTE, nonequilibrium populations, line profiles, and opacities for a model silicon atom, including charge exchange processes. This was achieved using the “minority species” version of RADYN. The inclusion of charge exchange resulted in a substantial fraction of Si iv at cooler temperatures than those predicted by ionization equilibrium. All simulations with an injected energy flux

erg cm−2 s−1 resulted in optical depth effects on the Si iv emission, with differences in both intensity and line shape compared to the optically thin calculation. Weaker flares (down to F ≈ 5 × 109 erg cm−2 s−1) also resulted in Si iv emission forming under optically thick conditions, depending on the other beam parameters. When opacity was significant, the atmospheres generally had column masses in excess of 5 × 10−6 g cm−2 over the temperature range 40–100 kK, and the Si iv formation temperatures were between 30 and 60 kK. We urge caution when analyzing Si iv flare observations, or when computing synthetic emission without performing a full radiation transfer calculation.
Discours constituant, austérité et néolibéralisme : des dynamiques énonciatives imbriquées. Le cas des Grandes Orientations des politiques économiques de l’Union européenne
Authors: Gobin Corinne 
Published: January 2019

Une partie de la production discursive de l’Union européenne (UE) relève de la catégorie du discours constituant, c’est-à-dire d’un discours qui fonde un nouveau rapport au monde, dans le cas étudié un nouveau rapport à la société humaine où l’économie de marché devient le principe moteur. Ce caractère constituant confère aux textes du corpus étudié, le texte annuel de grandes orientations des politiques économiques produits par l’UE depuis 1993, un profil neutre qui aide à banaliser l’idée que le néolibéralisme est l’unique bonne façon de penser l’économie. Grâce aux méthodes de la lexicométrie, les traits saillants – lexicaux et énonciatifs – de ce corpus sont examinés et font ressortir l’institution d’un monde agi et régi par l’économie elle-même où l’austérité réaliserait une stabilisation économique génératrice de la croissance, soit un levier pour parvenir à mettre en branle un automate parfait, préservé des instabilités politiques.

Abstract
Macrophages (MΦs) are heterogeneous and metabolically flexible, with metabolism strongly affecting immune activation. A classic response to proinflammatory activation is increased flux through glycolysis with a downregulation of oxidative metabolism, whereas alternative activation is primarily oxidative, which begs the question of whether targeting glucose metabolism is a viable approach to control MΦ activation. We created a murine model of myeloid-specific glucose transporter GLUT1 (Slc2a1) deletion. Bone marrow–derived MΦs (BMDM) from Slc2a1M−/− mice failed to uptake glucose and demonstrated reduced glycolysis and pentose phosphate pathway activity. Activated BMDMs displayed elevated metabolism of oleate and glutamine, yet maximal respiratory capacity was blunted in MΦ lacking GLUT1, demonstrating an incomplete metabolic reprogramming. Slc2a1M−/− BMDMs displayed a mixed inflammatory phenotype with reductions of the classically activated pro- and anti-inflammatory markers, yet less oxidative stress. Slc2a1M−/− BMDMs had reduced proinflammatory metabolites, whereas metabolites indicative of alternative activation—such as ornithine and polyamines—were greatly elevated in the absence of GLUT1. Adipose tissue MΦs of lean Slc2a1M−/− mice had increased alternative M2-like activation marker mannose receptor CD206, yet lack of GLUT1 was not a critical mediator in the development of obesity-associated metabolic dysregulation. However, Ldlr−/− mice lacking myeloid GLUT1 developed unstable atherosclerotic lesions. Defective phagocytic capacity in Slc2a1M−/− BMDMs may have contributed to unstable atheroma formation. Together, our findings suggest that although lack of GLUT1 blunted glycolysis and the pentose phosphate pathway, MΦ were metabolically flexible enough that inflammatory cytokine release was not dramatically regulated, yet phagocytic defects hindered MΦ function in chronic diseases.

Abstract The objective of this work is to contribute to the generation of a significant advance of the coconut agroindustry in Colombia, for which the process of spray drying was optimized to obtain coconut powder added with functionally active components (CP+PAC) (calcium and vitamins C, D3 and E), food that is framed in the context of functional foods. Initially, the behavior of the physicochemical properties of the coconut during storage at a temperature of 25ºC was evaluated. Then the base emulsion was designed, determining the influence of the composition of emulsions based on coconut milk, on its physicochemical stability, the answer surface methodology was used with a central composite design, considering the independent variables: water/coconut ratio; xantan gum; coconut fiber; terbutilhidroquinona. Subsequently, it was experimentally optimized according to the operating characteristics of the dryer and the product, using a response surface design based on five independent variables: Maltodextrin, air inlet temperature, air outlet temperature, atomizer disk speed and vacuum pressure in the drying chamber. Finally, the stability of the PC+PAC properties was evaluated, using a factorial design based on the independent variables: storage temperature, storage time and packaging.

A mathematical model of spray drying granulation process in formulation
Authors: Kagami Hiroyuki 
Published: January 2019

In this study, we apply the drying model of polymer solution coated on a flat substrate to the spray drying granulation process in formulation. In order to apply the former model to the drying of this spherical object, we consider this spherical object to be a stack of solution films applied on the spherical shell and discuss the drying process of each solution film. As a result, we see that the smaller the radius of curvature of the droplet, the more the fine particles tend to be unevenly distributed on the surface of the droplets during drying. Keywords: model, numerical simulation, spray drying granulation, spherical, droplets

A quality by design approach was used to investigate the influence of formulation composition and spray drying conditions on physicochemical properties of redispersable lipid based nanosystems loaded with Syzygium aromaticum essential oil. Four critical independent variables were studied: presence or absence of the liquid lipid oleic acid (0% - 1%), of the cationic surfactant CTAB (0% and 1%), inlet drying temperature (60 ºC -80 ºC), and ratio of the drying aids (ADJ) regarded to total formulation constituents weight (1:1 and 2:1). Resuls showed the production of spray dried redispersable lipid systems loaded with essential is feasible under very restrict conditions.

Moisture sorption isotherms and isosteric heat sorption of habanero pepper (Capsicum chínense) dehydrated powder
Authors: Luna-Flores Mario , Peña-Juarez Mariana Gisela , Bello-Ramirez Angélica Mara , Telis-Romero Javier , Luna-Solano Guadalupe 
Published: January 2019

Moisture sorption isotherms of the habanero pepper powder were determined using the Dynamic Vapor Sorption (DVS) method at 20, 25, 35, 45 and 55 °C in a range of water activity from 0.10 to 0.90 at which the processes of drying, packing and storage of habanero pepper are developed. The sorption capacity decreased with increasing temperature at a given water activity and the sorption isotherms showed a sigmoid form (Type II). The hysteresis phenomenon was observed in the sorption isotherms at all temperatures studied and it was more pronounced at temperatures high. The experimental sorption curves were fitting to the GAB, BET and Oswin models. It was concluded that the models that best describe the adsorption and desorption data for habanero pepper dehydrated powder were the GAB and Oswin models. The isosteric heat of water sorption was calculated with the moisture content data in equilibrium. The desorption isotherms present a higher isosteric heat in relation to the adsorption isotherms. In both, the isosteric heat decreased as the moisture content increased. Keywords: Habanero pepper dehydrated powder; Convective drying; Moisture sorption isotherms; Mathematic models
Biodrying process: a sustainable technology for treatment of municipal solid wastes organic fraction
Authors: Kechaou Nabil , Ammar E 
Published: January 2019

The Municipal Solid Waste of Agareb (Sfax –Tunisia), characterized by high organic fraction and moisture contents is the most worrying pollution source that must be managed by innovative treatment and recycling technologies. Bio-drying, as a waste to energy conversion technology, aims at reducing moisture content of this organic matter. This concept, similar to composting, is accomplished by using the heat generated from the microbial degradation of the waste matrix, while forced aeration is used. The purpose of this work was to reduce the moisture content of the waste, by maximizing drying and minimizing organic matter biodegradation, in order to produce a solid recovered fuel with high calorific value.Keywords: Municipal solid wastes; organic matter; biodrying; composting; energy recovery.

Authors: Oliveira Wanderley Pereira , Bankole Victor Oloruntoba , Souza Claudia Regina F. 
Published: January 2019

Harnessing the benefits of rosemary polyphenols is limited by variability in their physicochemical properties. These limitations may be overcome by encapsulation in systems possessing hydro-lipophilic centers thereby accommodating molecules of different polarities. Proliposomes offer a viable option in this regards, being particles which form liposomal suspension in water. Lyophilized extracts of rosemary was encapsulated in hydrogenatedsoyphosphatidylcholine/cholesterol by solvent replacement method. Spray dried proliposomes were obtained with lactose as carrier. Using Central Composite Design, the effects of lipid, extract and carrier concentrations on response variables including bioactive content and retention, moisture content characteristics, recuperation and redispersibility were evaluated by statistical analysis. Keywords: Polyphenols; antioxidant; proliposomes; spray drying
Civil society in times of change: shrinking, changing and expanding spaces and the need for new regulatory approaches
Authors: Anheier Helmut K. , Lang Markus , Toepler Stefan 
Published: January 2019

AbstractThe relationship between many G20 governments and organized civil society has become more complex, laden with tensions, and such that both have to find more optimal modes of engagement. In some instances, state-civil society relations have worsened, leading some experts and activists to speak of a “shrinking space” for civil society. How wide-spread is this phenomenon? Are these more isolated occurrences or indeed part of a more general development? How can countries achieve and maintain an enabling environment for civil society? The authors suggest that much of the current impasse results foremost from outdated and increasingly ill-suited regulatory frameworks that fail to accommodate a much more diverse and expanded set of civil society organizations (CSO). In response, they propose a differentiated model for a regulatory framework based on functional roles. Based on quantitative profiling and expert surveys, moreover, the paper also derives initial recommendations on how governments and civil society could find ways to relate to each other in both national and multilateral contexts.

Published: January 2019

PurposeOvarian torsion is the twisting of the ovary on its vascular pedicle resulting in vascular compromise. Diagnosis of ovarian torsion is challenging in patients who have atypical clinical or ultrasound (US) findings. The objective of our study was to demonstrate the magnetic resonance imaging (MRI) features of ovarian torsion to help radiologists make a conclusive diagnosis when the clinical and US findings are unclear.Material and methodsWe retrospectively reviewed the clinical and MRI features in 10 females with surgically proven ovarian torsion, who had inconclusive clinical, US, or computed tomography findings.ResultsAll patients showed a significantly enlarged ovary with size ranging from 5 to 18 cm. ‘Twisted ovarian pedicle’ sign was seen in seven patients. Eight cases showed areas of haemorrhage within the ovarian stroma. Non-enhancement of ovarian stroma was observed in six patients. Seven patients showed an ipsilateral deviation of the uterus.ConclusionsMRI features of ovarian torsion include ovarian enlargement, twisted ovarian pedicle, ovarian haemorrhage, abnormal ovarian enhancement, and ipsilateral deviation of the uterus. Awareness of these imaging features will enable the radiologist to recognise ovarian torsion and differentiate it reliably from other benign or malignant ovarian lesions.
Impacts of Transportation and Logistics on Brazilian Soybean Prices and Exports
Authors: Fliehr Olivia , Zimmer Yelto , Smith Linda H. 
Published: January 2019

Abstract
As Brazilian soybean exports doubled between 2001/02 and 2011/12 and major production areas consolidated in remote inland Cerrado regions, moving product to port has proven to be a challenge. A review of the literature, data analysis, and interviews with experts in the logistics chain revealed that a lack of grain storage, overreliance on trucking, poor road conditions, and inefficient operations at rail terminals and ports impede a smooth flow of grain from farm to port. Because of the comparatively low per-unit values of agricultural bulk commodities, transportation may account for a large share of the total cost of soybean exports. As a result, it was hypothesized that increases in transportation costs may reduce farm-gate prices, affecting producer profitability and, thus, national production. To test that hypothesis, this study examined transportation costs from inland production regions to traffic hubs and the Santos seaport. A comparison of theoretical producer prices calculated based on logistics costs versus actual local prices was employed to confirm that transport inefficiencies have led to depressed farm gate prices.

Restrictions on foreign funding of religious communities. A sensitive human rights issue
According to the Coalition Agreement 2017-2021, the Dutch government intends to develop policy to prevent religious communities from receiving support from abroad if this support comes from so-called ‘unfree countries’. In the article, the author argues that restrictive measures in this area touch upon the collective freedom of religion, which is protected by the ECHR, measures that can only be justified under strict conditions in the light of religious freedom as guaranteed in article 9 ECHR.
