Oxidative stress induces BH4 deficiency in male, but not female, SHR
Authors: Gillis Ellen E. , Brinson Krystal N. , Rafikova Olga , Chen Wei , Musall Jacqueline B. , Harrison David G. , Sullivan Jennifer C.
Published: June 2018

We previously published that female spontaneously hypertensive rats (SHR) have significantly greater nitric oxide (NO) bioavailability and NO synthase (NOS) enzymatic activity in the renal inner medulla (IM) compared with age-matched males, although the mechanism responsible remains unknown. Tetrahydrobiopterin (BH4) is a critical cofactor required for NO generation, and decreases in BH4 as a result of increases in oxidative stress have been implicated in the pathogenesis of hypertension. As male SHR are known to have higher levels of oxidative stress compared with female SHR, we hypothesized that relative BH4 deficiency induced by oxidative stress in male SHR results in lower levels of NOS activity in renal IM compared with females. Twelve-week-old male and female SHR were randomized to receive tempol (30 mg/kg/day via drinking water) or vehicle for 2 weeks. Tempol treatment did not affect blood pressure (BP) in either sex, but reduced peroxynitrite levels only in males. Females had more total biopterin, dihydrobiopterin (BH2), and BH4 levels in renal IMs than males, and tempol treatment eliminated these sex differences. Females had greater total NOS activity in the renal IM than males, and adding exogenous BH4 to the assay increased NOS activity in both sexes. This sex difference in total NOS and the effect of exogenous BH4 were abolished with tempol treatment. We conclude that higher oxidative stress in male SHR results in a relative deficiency of BH4 compared with females, resulting in diminished renal NOS activity in the male.
Medium-resolution integral-field spectroscopy for high-contrast exoplanet imaging
Authors: Hoeijmakers H. J. , Schwarz H. , Snellen I. A. G. , de Kok R. J. , Bonnefoy M. , Chauvin G. , Lagrange A. M. , Girard J. H.
Published: June 2018

Context. Angular differential imaging (ADI) and spectral differential imaging (SDI) are well-established high-contrast imaging techniques, but their application is challenging for companions at small angular separations from their host stars.

Aims. The aim of this paper is to investigate to what extent adaptive-optics assisted, medium-resolution (R ~ 5000) integral field spectrographs (IFS) can be used to directly detect the absorption of molecular species in the spectra of planets and substellar companions when these are not present in the spectrum of the star.

Methods. We analysed archival data of the β Pictoris system taken with the SINFONI integral field spectrograph located at ESO’s Very Large Telescope, originally taken to image β Pictoris b using ADI techniques. At each spatial position in the field, a scaled instance of the stellar spectrum is subtracted from the data after which the residuals are cross-correlated with model spectra. The cross-correlation co-adds the individual absorption lines of the planet emission spectrum constructively, while this is not the case for (residual) telluric and stellar features.

Results. Cross-correlation with CO and H2O models results in significant detections of β Pictoris b with signal-to-noise ratios (S/Ns) of 13.7 and 16.4 respectively. Correlation with a T = 1700 K BT-Settl model provides a detection with an S/N of 22.8. This in contrast to application of ADI, which barely reveals the planet. While the adaptive optics system only achieved modest Strehl ratios of 19–27% leading to a raw contrast of 1:240 at the planet position, cross-correlation achieves a 3σ contrast limit of 2.7 × 10−5 in this 2.5 hr data set, a factor ~40 below the raw noise level at an angular distance of 0.36′′ from the star.

Conclusions. Adaptive-optics assisted, medium-resolution IFS, such as SINFONI on the VLT and OSIRIS on the Keck Telescope, can be used for high-contrast imaging utilizing cross-correlation techniques for planets that are close to their star and embedded in speckle noise. We refer to this method as molecule mapping, and advocate its application to observations with future medium resolution instruments, in particular ERIS on the VLT, HARMONI on the ELT and NIRSpec, and MIRI on the JWST.
Studying star forming dwarf galaxies in Abell 779, Abell 1367, Coma, and Hercules clusters
Authors: Vaduvescu O. , Petropoulou V. , Reverte D. , Pinter V.
Published: June 2018

Context. We continue to study star formation in dwarf galaxies located in nearby clusters.

Aims. Known physical and chemical relations outlining the formation and evolution of dwarfs is compared in different environments, including the Local Volume (LV) and some nearby clusters studied previously.

Methods. We used the TNG telescope for four nights in 2010 to acquire deep near-infrared imaging in K′ of 45 star forming dwarf galaxies located in the Abell 779, Abell 1367, Abell 1656 (Coma), and Abell 2151 (Hercules) clusters.

Results. Surface photometry was approached based on past experience by using the sech law to account for the outer old stellar contribution plus a Gaussian component to model the inner starburst, proving the blue compact dwarf (BCD) classification of most targets. Sech central surface brightness, semimajor axis, sech, and total apparent magnitude were measured, allowing to estimate size, absolute luminosity and mass for all targets.

Conclusions. The physical correlations between size, central brightness, and NIR luminosity appear to hold, but previously known linear fits break above MSK  =   − ​19 for Abell 779, Abell 1367 and especially for Hercules, while the dwarf fundamental plane (FP) is probed by only half cluster members, suggesting harassment by the denser cluster environments. Nevertheless, the chemical relations between the oxygen abundance, luminosity, gas mass, baryonic mass, and gas fraction in a closed box model are probed by most members of the four studied clusters, and the starburst grows linearly with the K′ luminosity.
The curious case of Mars’ formation
Authors: Woo Jason Man Yin , Brasser Ramon , Matsumura Soko , Mojzsis Stephen J. , Ida Shigeru
Published: June 2018

Dynamical models of planet formation coupled with cosmochemical data from martian meteorites show that Mars’ isotopic composition is distinct from that of Earth. Reconciliation of formation models with meteorite data require that Mars grew further from the Sun than its present position. Here, we evaluate this compositional difference in more detail by comparing output from twoN-body planet formation models. The first of these planet formation models simulates what is termed the “Classical” case wherein Jupiter and Saturn are kept in their current orbits. We compare these results with another model based on the “Grand Tack”, in which Jupiter and Saturn migrate through the primordial asteroid belt. Our estimate of the average fraction of chondrite assembled into Earth and Mars assumes that the initial solid disk consists of only sources of enstatite chondrite composition in the inner region, and ordinary chondrite in the outer region. Results of these analyses show that both models tend to yield Earth and Mars analogues whose accretion zones overlap. The Classical case fares better in forming Mars with its documented composition (29–68% enstatite chondrite plus 32–67% ordinary chondrite) though the Mars analogues are generally too massive. However, if we include the restriction of mass on the Mars analogues, the Classical model does not work better. We also further calculate the isotopic composition of17O,50Ti,54Cr,142Nd,64Ni, and92Mo in the martian mantle from the Grand Tack simulations. We find that it is possible to match the calculated isotopic composition of all the above elements in Mars’ mantle with their measured values, but the resulting uncertainties are too large to place good restriction on the early dynamical evolution and birth place of Mars.
Tunnelling dominates the reactions of hydrogen atoms with unsaturated alcohols and aldehydes in the dense medium
Authors: Zaverkin V. , Lamberts T. , Markmeyer M. N. , Kästner J.
Published: June 2018

Hydrogen addition and abstraction reactions play an important role as surface reactions in the buildup of complex organic molecules in the dense interstellar medium. Addition reactions allow unsaturated bonds to be fully hydrogenated, while abstraction reactions recreate radicals that may undergo radical–radical recombination reactions. Previous experimental work has indicated that double and triple C–C bonds are easily hydrogenated, but aldehyde –C=O bonds are not. Here, we investigate a total of 29 reactions of the hydrogen atom with propynal, propargyl alcohol, propenal, allyl alcohol, and propanal by means of quantum chemical methods to quantify the reaction rate constants involved. First of all, our results are in good agreement with and can explain the observed experimental findings. The hydrogen addition to the aldehyde group, either on the C or O side, is indeed slow for all molecules considered. Abstraction of the H atom from the aldehyde group, on the other hand, is among the faster reactions. Furthermore, hydrogen addition to C–C double bonds is generally faster than to triple bonds. In both cases, addition on the terminal carbon atom that is not connected to other functional groups is easiest. Finally, we wish to stress that it is not possible to predict rate constants based solely on the type of reaction: the specific functional groups attached to a backbone play a crucial role and can lead to a spread of several orders of magnitude in the rate constant.
Gaia DR2 view of the Lupus V–VI clouds: The candidate diskless young stellar objects are mainly background contaminants

Published: June 2018

Extensive surveys of star-forming regions with Spitzer have revealed populations of disk-bearing young stellar objects. These have provided crucial constraints, such as the timescale of dispersal of protoplanetary disks, obtained by carefully combining infrared data with spectroscopic or X-ray data. While observations in various regions agree with the general trend of decreasing disk fraction with age, the Lupus V and VI regions appeared to have been at odds, having an extremely low disk fraction. Here we show, using the recent Gaia data release 2 (DR2), that these extremely low disk fractions are actually due to a very high contamination by background giants. Out of the 83 candidate young stellar objects (YSOs) in these clouds observed by Gaia, only five have distances of ~150 pc, similar to YSOs in the other Lupus clouds, and have similar proper motions to other members in this star-forming complex. Of these five targets, four have optically thick (Class II) disks. On the one hand, this result resolves the conundrum of the puzzling low disk fraction in these clouds, while, on the other hand, it further clarifies the need to confirm the Spitzer selected diskless population with other tracers, especially in regions at low galactic latitude like Lupus V and VI. The use of Gaia astrometry is now an independent and reliable way to further assess the membership of candidate YSOs in these, and potentially other, star-forming regions.
Methodical approach to determination of costs at the initial stages of the project research of gas-supply systems
Authors: Kirillova Ariadna , Gorelova Anna
Published: June 2018

The article deals with topical issues at the pre-investment stage of project design to justify decisions on the feasibility of further investment and the transition to the next stage of design - the development of project documentation. At the pre-project stage, there is often a situation when the parameters of structures have not yet been determined, and capital investments must be evaluated. Methodological approaches to determining the cost of gasification facilities and the estimated model of cost calculations at the stage of investment justification with the help of enlarged indicators that improve the accuracy and validity of calculations at the stage of pre-design studies are substantiated. It is shown that the enlarged indicators used at the stage of investment justification form the regulatory basis for determining the cost of gasification facilities, for estimating capital costs, as well as for evaluating the effectiveness of investments in the selection of project options. The object of the study adopted electrically welded steel pipes and polyethylene pipes for gas pipelines. Evaluation and forecasting of the cost of gas distribution systems in the article are proposed using regression models depending on time and diameter of the pipe. The regression dependences of the cost of steel and polyethylene pipes of all standard sizes and confidence intervals for the cost of pipes allow to estimate also possible errors of the forecast cost estimation.

Authors: Gusakova Elena
Published: June 2018

Conceptual planning and implementation of large-scale real estate development projects is one of the most difficult tasks in the organization of construction. In the Russian practice, a large experience of development, complex reorganization and redevelopment of large development areas is accumulated. The methodological basis for solving similar problems is the organizational and technological genesis, which considers the development of the project during the full life cycle. An analysis of this experience allows us to talk about the formation of new and effective approaches and methods within the organizational and technological genesis. Among them, the most significant and universal approaches should be highlighted: The concept of real estate development, which explains the reasons and objective needs for project transformations during its life cycle, as well as to increase the adaptive capabilities of design decisions and the project's suitability for the most likely future changes; Development project of joint action, which is based on the balance of interests of project participants; Master planning of the life cycle stages of the project and subprojects, based on the rethinking of the theory and methods of the construction organization, and allowing rationally localized construction sites and related subprojects, while retaining the remaining development and development area beyond of the negative effect of construction for comfortable living and work.

Outsourcing creates workplaces outside the framework of TNCs, but in frames of the national economy. From our point of view this is a way to maximize the financial result. Unemployment, even technical, increases social spending. At the same time, the idea of basic income should change the priorities in the system of distribution of the reproduction result. The key beneficiary of sharing-economy approach is a consumer, who can save something on intermediaries or transaction costs. The development of sharing economy rather indicates that TNCs are not planning to lower their rate of return. However, the growing technological unemployment simultaneously with the stimulation of demand found a solution. The solution is the joint consumption of goods produced by the sharing economy. Historical examples of solution to the problem of distribution clearly demonstrate the importance of transforming the reproductive cycle’s financial architecture. The models operating on the basis of fair distribution have not only prospects of development, but also are capable to change society attitude to the concept and approaches to consumption.

Modern street crime has been increasingly affecting the formation of the criminogenic situation in Russia. The main goal of this paper is exploring the possible application of modern digital technologies in the evaluation and prevention of public crime. The methods presented in this empirical research are: monitoring, statistical methods, modeling and questioning, content analysis, research result processing. As a result of the analysis of the received data, generalized quantitative and qualitative indicators of modern street crime were presented: prevalence of mercenary and violent crimes (61,4%) in the current criminal situation in the city streets (structure of street crime); the percentage of street crime in relation to all crime done in public places is 45,0% with the rising tendency of serious crime and latency; places where street crime takes place are empty, open city spaces composing about 12% of all the streets of the city; the prevailing “work schedule” of a street criminal is determined by the time of the year (fallwinter); day of the week (Friday, weekends and holidays) and time of day (evening-night); the increase in mobile phone theft from people passing in the streets; a characteristic way of street theft and robbery is their suddenness and unpredictability. The article supports the conclusion that the current system of street crime prevention methods and its practice doesn`t provide salvation from street criminals and thus requires further improvement with the consideration of the rising possibilities of the internet-space, specifically, usage of digital applications and devices.
