Scientific and Practical Problems. To the Question about Motivation for the Study of the Sciences
Authors: Gutner Grigory B. 
Published: September 2018

The question about the motivation of students at all levels of education in the study of various scientific disciplines is discussed. Lack of motivation is often happened due to the fact that scientific problems are by their nature very different from those, which a person facing in her/his everyday practice. The scientific problem arises when the outside world is allocated into the object to which a person have totally non-pragmatic research interest. Usually everyday tasks are associated with the attainment of specific practical aims. The specifics of everyday tasks are researched in this article. For this Analytics of Dasein, which is developed by Martin Heidegger, is involved. The world of everyday life is described as a set of "Zuhanden" in the horizon of which a human being opens up a variety of vital possibilities. These possibilities involve the use of objects as tools. The scientific problem arises when in this set of tools something wondrous is found. It is the wonderment which turns the thing into an object. It is shown that wonderment is an "existential" on the one hand, akin to terror, and on the other hand, opposite to him. Horror, according to Heidegger, arises when one confronts with nothing, while the wonderment accompanies the opening of being. The connection of horror and wonderment at the emergence of scientific problems is demonstrated on the example of the scientific biographies of Descartes and Einstein.

Published: September 2018

Some concepts of collective action have been examined. It is found that collective action is formed as a result of interaction of individuals within the group, collective etc. Such social environment in which collective action appears, is the educational process, which aims to provide protection, safety and educational needs of direct interaction between the preschool children and children of younger school age.
The forms of work: group and collective, have been analyzed. It is found that acting in a group or team, the participants of educational process gather around the common goal, collective action, that occurs, becomes the value in the process of achieving this goal. That is, it encourages the collective, group to act in the given direction. This action is accompanied by the interaction, due to which raises the phenomenology of collective, above- and beyond the individual.
It is based on the formation in the mind of each individual subject of communication the subjective model of the content and the process of interaction, which seems to be shared with other participants (the subject feels as if its co-author) and the presence of which can be displayed in the form of a general image of the subject of interaction that occurs in interpersonal space and fills it.

Serratia marcescens (S. marcescens) is a Gram negative bacilli in the family Enterobactericea and is an important cause of health care-related infections and intensive care outbreaks. In this article, an 82-year-old female patient admitted to bed, who was a persistent urinary tract infection due to bacteremic urinary tract infection due to S. marcescens, was referred to the literature. In conclusion, it should be kept in mind that S. marcescens and other Gram-negative bacteria may cause bacteraemia-induced urinary tract infections especially in bedridden patients who have persistent urinary incontinence, and urine culture and blood cultures should be taken in these patients.

Published: September 2018

This paper seeks to identify and discusses the factors that affect an organization’s internal whistleblowing intentions related to ethics. This paper integrates theindividual variable which are ethical judgment and the intensity of the moral; organizational variable that support the organizations; and situational variables, such as the status of wrongdoers, the possibility of retaliation, and tolerance of dissent;that is expressed in a group of theoretical propositions, which is used to develop a frame of thoughts in the study. This paper attempts to provide useful knowledges on how individuals form the intention of reporting and how ethical values can affect these intentions, thus, itwill be able to provide a contribution for a further understanding of the phenomena associated with an ethical whistleblowing.The purpose of this paper is to provide a general discussion about the decision-making process of internal whistleblowing along with an overview of the ethical element that is reflected in the psychological, situational and organizational characteristics. Through a theoretical model, based on the existing literature, it indicates that whistleblowing is a very complex phenomenon resulted from an interaction of situational, organizational and individualfactors. The complexity of the phenomenon depends not only on the various factors that affect whistleblowing, but also related to the attitudes toward the ethical judgment and moral intensity. Whistleblowing behavior is embedded in a social context, so it can vary according to the values, beliefs and certain social norms. Factors that may inhibit the whistleblowingbehavioris a violation of the personal relationship between employee and employer, aversion to conflict, and interpersonal relations. The passivity of the employees can weaken the relationship between whistleblowing attitudes andwhistleblowingintentions, therefore,it causes the observer to not disclose the information.Specifically, organizations must improve the legitimacy of an internal whistleblowing and take actions that can reduce the fear of retaliation, increase the perceived support and easily identify the actions and behaviors that must be reported. By expanding the knowledge of the phenomenon and discussing the aspects and its implications, hence, it may encourage any debates on the topic and encourage organizations to rethink their policies and strategies for whistleblowing decision making.

Abstract
We present XMM-Newton imaging spectroscopy of 10 weak emission-line quasars (WLQs) at

, six of which are radio-quiet, and four that are radio-intermediate. The new X-ray data enabled us to measure the power-law photon index, at rest-frame energies >2 keV, in each source with relatively high accuracy. These measurements allowed us to confirm previous reports that WLQs have steeper X-ray spectra, suggesting higher accretion rates with respect to “typical” quasars. A comparison between the photon indices of our radio-quiet WLQs and those of a control sample of 85 sources shows that the first are significantly higher, at the ≳3σ level. Collectively, the four radio-intermediate WLQs have lower photon indices with respect to the six radio-quiet WLQs, as may be expected if the spectra of the first group are contaminated by X-ray emission from a jet. Therefore, in the absence of significant jet emission along our line of sight, these results are in agreement with the idea that WLQs constitute the extreme high end of the accretion-rate distribution in quasars. We detect soft excess emission in our lowest-redshift radio-quiet WLQ, in agreement with previous findings suggesting that the prominence of this feature is associated with a high accretion rate. We have not detected signatures of Compton reflection, Fe Kα lines, or strong variability between two X-ray epochs in any of our WLQs, which can be attributed to their relatively high luminosity.
Radial Convection in Hot Accretion Flows
Authors: Ghasemnezhad Maryam , Samadi Maryam 
Published: September 2018

Abstract
In this work, we study the vertical structure of a hot accretion flow by taking into account radial transportation of angular momentum and energy due to the presence of turbulence, convection, and outflow. We write the hydrodynamics equations in the spherical coordinates, and, based on the assumptions of axisymmetric and steady state, we simplify the basic equations. Employing self-similar solutions in the radial direction and finding proper boundary conditions, we solve the ordinary differential equations with respect to the polar angle. Considering the meridional component of the velocity field, we find inflow–outflow solutions. In order to formulate the convection term, we introduce two parameters, i.e., α

c
and g as free parameters. The first one is called the convection parameter and the greater value of it makes the convection more effective in changing the flow dynamics. The second one, g, varies between zero and unity (where g = 1 implies that the convection behaves similarly to the turbulence viscosity and g = 0 means the convection behaves in the opposite direction of viscosity). Our results show that the accretion rate decreases with greater α

c
and it makes the disk warmer and intensifies the outflows from the disk's surface. On the other hand, the g parameter affects the flow in an opposite manner compared to the convection parameter and makes the disk rotate and accrete faster.
Oxygen Isotopic Exchange between Amorphous Silicate and Water Vapor and Its Implications for Oxygen Isotopic Evolution in the Early Solar System
Authors: Yamamoto Daiki , Kuroda Minami , Tachibana Shogo , Sakamoto Naoya , Yurimoto Hisayoshi 
Published: September 2018

Abstract
Meteoritic evidence suggests that oxygen isotopic exchange between 16O-rich amorphous silicate dust and 16O-poor water vapor occurred in the early solar system. In this study, we experimentally investigated the kinetics of oxygen isotopic exchange between submicron-sized amorphous forsterite grains and water vapor at protoplanetary disk-like low pressures of water vapor. The isotopic exchange reaction rate is controlled either by diffusive isotopic exchange in the amorphous structure or by the supply of water molecules from the vapor phase. The diffusive oxygen isotopic exchange occurred with a rate constant D (m2 s−1) = (1.5 ± 1.0) × 10−19 exp[−(161.5 ± 14.1 (kJ mol−1))R
−1(1/T−1/1200)] at temperatures below ∼800–900 K, and the supply of water molecules from the vapor phase could determine the rate of oxygen isotopic exchange at higher temperatures in the protosolar disk. On the other hand, the oxygen isotopic exchange rate dramatically decreases if the crystallization of amorphous forsterite precedes the oxygen isotopic exchange reaction with amorphous forsterite. According to the kinetics for oxygen isotopic exchange in protoplanetary disks, original isotopic compositions of amorphous forsterite dust could be preserved only if the dust was kept at temperatures below 500–600 K in the early solar system. The 16O-poor signatures for the most pristine silicate dust observed in cometary materials implies that the cometary silicate dust experienced oxygen isotopic exchange with 16O-poor water vapor through thermal annealing at temperatures higher than 500–600 K prior to their accretion into comets in the solar system.
The Fargo Method for Keplerian Advection: Error Analysis and Correction
Authors: Shariff Karim , Wray Alan 
Published: September 2018

Abstract
The Fargo method alleviates the time-step constraint due to Keplerian advection by shifting flow quantities an integer number of grid intervals in the azimuthal direction. We point out that the implied change of the azimuthal coordinate means that all radial derivatives must carry an extra operator,

, which is not present in current implementations and therefore implies an error. Here, t
0 is time at the beginning of a time step,

is the rotation rate in the coordinate transformation, and ϕ is the azimuthal coordinate. If the quantity

were smooth, the factor

would imply that the error is first-order in time. However, integerization in the original Fargo scheme means that

is a δ-function wherever

suffers a jump, so the error becomes unbounded (but more localized) in a finite-difference or finite-volume setting as the radial grid size

. Numerical tests showed that the original Fargo method produces noticeable errors where

has a jump. These errors are advected by the flow into the rest of the domain. Even if integerization were not employed, the Fargo code is second-order in time and evaluates transport terms at

therefore, the extra operator

still cannot be neglected. The correction proposed here is to perform a continuous-in-r shift at the end of each time step using a fast Fourier transform and to include the additional operator. Simulation tests including cpu times are provided for a scheme that is fourth-order in space and time.
The Effect of Jupiter's Formation on the Distribution of Refractory Elements and Inclusions in Meteorites
Authors: Desch Steven J. , Kalyaan Anusha , Alexander Conel M. O’D. 
Published: September 2018

Abstract
We present a comprehensive evolutionary model of the Sun’s protoplanetary disk, constructed to resolve the “CAI storage problem” of meteoritics. We predict the abundances of calcium-rich, aluminum-rich inclusions (CAIs) and refractory lithophile elements under the central assumption that Jupiter’s ∼30 M
⊕ core formed at about 3 au at around 0.6 Myr and opened a gap. CAIs were trapped in the pressure maximum beyond Jupiter; carbonaceous chondrites formed there. Inside Jupiter’s orbit, CAIs were depleted by aerodynamic drag; ordinary and enstatite chondrites formed there. For 16 chondrites and achondrites, we review meteoritic data on their CAI and refractory abundances and their times of formation, constrained by radiometric dating and thermal models. We predict their formation locations, finding excellent consistency with other location information (water content, asteroid spectra, and parent bodies). We predict the size of particles concentrated by turbulence for each chondrite, finding excellent matches to each chondrite’s mean chondrule diameter. These consistencies imply meteorite parent bodies assembled quickly from local materials concentrated by turbulence, and usually did not migrate far. We predict CI chondrites are depleted in refractory lithophile elements relative to the Sun, by about 12% (0.06 dex). We constrain the variation of the turbulence parameter α in the disk and find a limited role for magnetorotational instability, favoring hydrodynamical instabilities in the outer disk, plus magnetic disk winds in the inner disk. Between 3 and 4 Myr at least, gas persisted outside Jupiter but was depleted inside it, and the solar nebula was a transition disk.
A Large-scale Survey of CO and Its Isotopologues toward the Rosette Molecular Cloud

Abstract
Using the PMO-13.7 m millimeter telescope at Delingha in China, we have conducted a large-scale simultaneous survey of 12CO, 13CO, and C18O J = 1 − 0 emission toward the Rosette molecular cloud (RMC) region with a sky coverage of 3.°5 × 2.°5. The majority of the emission in the region comes from the RMC complex, with velocities lying in the range from −2 to 20.5 km s−1. Beyond this velocity range, 73 molecular clumps are identified with kinematic distances from 2.4 to 11 kpc. Based on the spatial and velocity distribution, nine individual clouds, C1–C9, have been identified for the RMC complex. It appears that the C3 cloud is different from other clouds in the RMC complex in view of its characteristic velocity, excitation temperature, and velocity dispersion. Most of the young stellar clusters in the region are located in positions of both high column density and high excitation temperature. Seven new molecular filaments are discovered in the RMC complex. Evidence for cloud–cloud collision is found in the region of young stellar clusters REFL9 and PouF, showing that these young stellar clusters probably result from a cloud–cloud collision. The abundance ratios of 13CO to C18O in the region have a mean value of 13.7, which is 2.5 times larger than the solar system value, showing that UV photons from the nearby OB clusters have a strong influence on the chemistry of clouds in the RMC complex.
Biotic distribution within groundwater- is it really unpredictable?
Authors: Korbel Kathryn , Chariton Anthony , Hose Grant 
Published: September 2018

Distribution of biota within groundwater is often patchy, and attributed to the heterogeneity of the aquifer environment. Geology and hydrological connectivity are often the factors that most influence water chemistry and habitat availability thus biota, however phreatophytic trees, other sources of carbon and nutrients may also influence biotic distribution. Critically, limited knowledge on the relative importance of such factors on the distribution of groundwater biota makes it difficult to distinguish natural variation from human impacts on groundwater ecosystems, thus inpact our ability to undertake biomonitoring of ecosystem health.
This study uses complementary field surveys and laboratory studies to unravel the relative influence of water quality, climate, and sediment size on biotic communities. Field surveys combined traditional pumping and net collections with eDNA community profiling (metabarcoding) of 16S rDNA to characterise groundwater microbes in shallow alluvial aquifers within the Murray-Darling Basin, Australia. Laboratory studies examined the influence of sediment size on stygobiotic amphipods, syncarids and copepods.
For stygofauna, sediment size, and thus size of interstitial voids, is a key limiting factor. For microbes, water chemistry influences microbial activity and functional processes, which may in turn influence biogeochemical cycling and ecosystem services provided by groundwater ecosystems.
