BALLAST WATER POLLUTION RISK ASSESSMENT IN THE BLACK SEA
Authors: RAŢᾸ Vasile , RUSU Liliana 
Published: April 2021

Since the emergence of humanity, the marine environment has provided a safety net in many ways, has fostered socio-economic development, creating links between states, between continents. In the same time, it represents a priority source of food for a considerable percentage of the population. The same marine environment also creates solutions to current global problems, as a potential source of sustainable energy for the future. In recent decades, the stability of this ecosystem has been considerably shaken by the various types of pollution resulting from human activities. The Black Sea is not immune to these results from economic activities, such as the transport of goods by water, which creates the context for the migration of living organisms from one geographical region to another. The threat of ecosystems has been intensified by the process of globalization, by changing the natural food chains following the accidental introduction of non- indigenous marine life by discharging ballast water from ship tanks. Risk assessment to limit the effects of this biohazard problem is the first step in a normal regional chain of action..

Authors: Kulik Oleg 
Published: April 2021

One of the priority direction of the personnel work in the Ministry of the Internal Affairs of Russia today is to ensure the intended use of personnel and except the cases of assigning the excessive official duties to the officers of the internal affairs bodies that are not related to their posts. At the same time, much attention is paid to the implementation of the officers’ rights, aimed not only at the successful realization of law enforcement functions, but also have a compensating, stimulating nature.
In this regard, the target of the article is to point out the dependence between the effectiveness of the internal affairs officers work, the satisfaction with their service conditions and the balance of their rights and official duties. The state of this balance and the possibility of its change are reflected in the main legislative and other regulatory legal acts establishing the legal status of internal affairs bodies’ officers. In addition to the analysis of the listed documents, the article separately considers the procedure of compiling and using job regulations (job instructions) as documents directly regulating official activities.
The result of the research is the recommendations for amending the regulatory legal acts and improving the organizational foundations, which allow providing the balance of the officers’ rights and service duties.

Published: April 2021

Abstract
If the properties or morphologies of a material are optimized, magnetic orientation occurs even at the electromagnet level. To apply a rotational magnetic field, we used finite-integration technique to design a quadrupole electromagnet based on estimated magnetic field-strength distributions and magnetic flux vectors. The generation of a seamless 0.33 T rotating magnetic field without moving parts is demonstrated. It will be possible to adopt it for targets, such as material preparations or body parts, that cannot be examined with the conventional turntable method.

Published: April 2021

Poor handling and storage practices reduce the manure quality as a fertilizer. A survey was done in the Seke communal area, Zimbabwe to establish common manure management practices, determine factors that influence use of manure and determine effects of the manure management practices on vegetable yield. A structured questionnaire was administered to 222 respondents from April to August 2019. Both descriptive and inferential statistics were done using SPSS. Chi-square tests and Spearman rank correlation were done to test for associations and the non-cause-effect relationship between different independent variables and farmers’ management practice of manure respectively. 88% of the respondents owned <1 ha of land and chicken manure was frequently (51%) used but with least (<0.5 t/ha) application quantities. Cattle manure was applied in largest (> 0.5 t/ha) quantities and >50% of the farmers were void of information on animal manure management. Fencing only was the common type of animal housing but had negative effects on quantity and quality of the manure. Drylot was most common (90%) manure management practice and different manure management practices had significantly (P<0.05) varied effects on vegetable yield. Drying manure resulted in significantly (P<0.05) low losses in manure quality. Generally, poultry and pigs manure had higher nutrient content compared to cattle and goat manure. Animal housing affected the quantity and quality of the manures as a fertilizer. Extension service programs like vocational training on manure management, exposure visits between farmers as well as a lead farm approach are necessary.

Authors: M Alhassan , Aleiro Muhammad Sani , A.U Umar 
Published: April 2021

Effluents from dye and dyeing industries constitute serious environmental threat and attracting serious attention. Activated carbon prepared from guinea corn husk and maize cobs waste materials was used as a precursor to prepare activated carbon. Variable ratios of the constituent ashes ( 1:1, 1:3 and 3:1) were prepared. The husk and cobs were ashed in a murfle furnace at 400-500oC for 2.5 h. Acid activation was carried out by washing with HCl (1M) after which it was characterized using XRF which revealed (in variable proportions) the presence of SiO2, Al2O3 and Fe2O3 as dominant oxides in the ashes. Waste water decolourization efficiency of the adsorbents was tested using dye waste water at same contact time using variable absorbent dosage. Higher moisture (96.80±0.56), Ash (12.90±0.35), pH (6.3±0.17), Conductivity (208±1.34) and Bulk density (12.27±0.61) were obtained for guinea corn husk. The best clearity was obtained after batch adsorption experiments at 1:1 which gave the highest adsorption at equilibrium (Qe) of 28.55 compared to 12.750 and 10.900 obtained for 1;3 and 3:1 respectively.

AbstractPsychology faces a measurement crisis, and mind-wandering research is not immune. The present study explored the construct validity of probed mind-wandering reports (i.e., reports of task-unrelated thought [TUT]) with a combined experimental and individual-differences approach. We examined laboratory data from over 1000 undergraduates at two U.S. institutions, who responded to one of four different thought-probe types across two cognitive tasks. We asked a fundamental measurement question: Do different probe types yield different results, either in terms of average reports (average TUT rates, TUT-report confidence ratings), or in terms of TUT-report associations, such as TUT rate or confidence stability across tasks, or between TUT reports and other consciousness-related constructs (retrospective mind-wandering ratings, executive-control performance, and broad questionnaire trait assessments of distractibility–restlessness and positive-constructive daydreaming)? Our primary analyses compared probes that asked subjects to report on different dimensions of experience: TUT-content probes asked about what they’d been mind-wandering about, TUT-intentionality probes asked about why they were mind-wandering, and TUT-depth probes asked about the extent (on a rating scale) of their mind-wandering. Our secondary analyses compared thought-content probes that did versus didn’t offer an option to report performance-evaluative thoughts. Our findings provide some “good news”—that some mind-wandering findings are robust across probing methods—and some “bad news”—that some findings are not robust across methods and that some commonly used probing methods may not tell us what we think they do. Our results lead us to provisionally recommend content-report probes rather than intentionality- or depth-report probes for most mind-wandering research.
Molecular gastronomy-an incentive for innovative research of various aspects related to the nutrition process
Authors: Kim Igor , Megeda Evgeniy 
Published: April 2021

The growing competition in the market of food manufacturers in recent years makes more and more demands on the quality and consumer appeal of food products. The necessity of continuous improvement of the senso-ry properties of products determines high requirements for the professional knowledge of industrial technol-ogists. Today, there is no doubt that the food industry is experiencing a significant shortage of specialists who have systemic and commercially applicable knowledge of both the organoleptic analysis itself and the mechanisms of molecular transformations and processes that affect the formation of sensory properties of food.
The modern scientific discipline "Molecular gastronomy" has significant potential for systematizing knowledge regarding mechanisms of chemical and physical changes that occur in a product during techno-logical processing, and their influence on the formation of organoleptic properties of products. We believe that the inclusion of this discipline in the educational process to study specialists of the directions "Food products of animal origin" and "Food products from vegetable raw materials" is highly-demanded and well-timed. In the fishing industry, the studying of technologists for this discipline can be implemented within the profiles ''Technology of products from aquatic biological resources'' and ''Food biotechnology of aquatic or-ganisms''. This discipline can be included both in the preparation of bachelors within these profiles, and in the educational program for the preparation of masters.

Abstract
The object FRB 20180916B is a well-studied repeating fast radio burst source. Its proximity (∼150 Mpc), along with detailed studies of the bursts, has revealed many clues about its nature, including a 16.3 day periodicity in its activity. Here we report on the detection of 18 bursts using LOFAR at 110–188 MHz, by far the lowest-frequency detections of any FRB to date. Some bursts are seen down to the lowest observed frequency of 110 MHz, suggesting that their spectra extend even lower. These observations provide an order-of-magnitude stronger constraint on the optical depth due to free–free absorption in the source’s local environment. The absence of circular polarization and nearly flat polarization angle curves are consistent with burst properties seen at 300–1700 MHz. Compared with higher frequencies, the larger burst widths (∼40–160 ms at 150 MHz) and lower linear polarization fractions are likely due to scattering. We find ∼2–3 rad m−2 variations in the Faraday rotation measure that may be correlated with the activity cycle of the source. We compare the LOFAR burst arrival times to those of 38 previously published and 22 newly detected bursts from the uGMRT (200–450 MHz) and CHIME/FRB (400–800 MHz). Simultaneous observations show five CHIME/FRB bursts when no emission is detected by LOFAR. We find that the burst activity is systematically delayed toward lower frequencies by about 3 days from 600 to 150 MHz. We discuss these results in the context of a model in which FRB 20180916B is an interacting binary system featuring a neutron star and high-mass stellar companion.
The Solar-cycle Variations of the Anisotropy of Taylor Scale and Correlation Scale in the Solar Wind Turbulence
Authors: Zhou G. , He H.-Q. 
Published: April 2021

Abstract
The field-aligned anisotropy of the solar wind turbulence, which is quantified by the ratio of the parallel to the perpendicular correlation (and Taylor) length scales, is determined by simultaneous two-point correlation measurements during the time period 2001–2017. Our results show that the correlation scale along the magnetic field is the largest, and the correlation scale in the field-perpendicular directions is the smallest, at both solar maximum and solar minimum. However, the Taylor scale reveals inconsistent results for different stages of the solar cycles. During the years 2001–2004, the Taylor scales are slightly larger in the field-parallel directions, while during the years 2004–2017, the Taylor scales are larger in the field-perpendicular directions. The correlation coefficient between the sunspot number and the anisotropy ratio is employed to describe the effects of solar activity on the anisotropy of solar wind turbulence. The results show that the correlation coefficient regarding the Taylor scale anisotropy (0.65) is larger than that regarding the correlation scale anisotropy (0.43), which indicates that the Taylor scale anisotropy is more sensitive to the solar activity. The Taylor scale and the correlation scale are used to calculate the effective magnetic Reynolds number, which is found to be systematically larger in the field-parallel directions than in the field-perpendicular directions. The correlation coefficient between the sunspot number and the magnetic Reynolds number anisotropy ratio is −0.75. Our results will be meaningful for understanding the solar wind turbulence anisotropy and its long-term variability in the context of solar activity.
Conditions for Superwind Classes of Super Star Clusters

Published: April 2021

Abstract
Mechanical feedback from young massive stars in super star clusters contributes to the formation of superwinds and superbubbles in star-forming regions. We conduct hydrodynamic simulations using the non-equilibrium ionization package maihem to explore how outflow velocity, mass-loading, metallicity, and ambient density can affect the occurrence of catastrophic cooling. To predict optical and UV emission lines, we apply the photoionization code cloudy to the physical conditions predicted by our hydrodynamic simulations. Our results could be useful for characterizing catastrophic cooling in starburst regions like the nearby Green Peas and distant star-forming galaxies.
Relevant Coma Composition Investigations for the Comet Interceptor Mission
Authors: Boice Daniel C. , Kobayashi Hitomi , Kawakita Hideyo , Shinnaka Yoshiharu 
Published: April 2021

Abstract
The Comet Interceptor Mission (ESA/JAXA) aims to visit a long-period comet or interstellar object. Its primary science goals are to characterize the object's shape, structure, and the composition of its surface and gas coma. The mission consists of three spacecraft, the primary and two accompanying ones. The focus of this paper is the unique synergetic activities between two mass spectrometers to investigate the chemical composition of the coma, one on the primary spacecraft and another on an accompanying spacecraft. Both can be operated in a complementary fashion, at different locations and at the same time, to sort out spatial from temporal effects. Relevant investigations of the coma composition and chemistry within the technical specifications of the instruments could address several unsolved questions. The Comet Interceptor Mission is posed to be an important mission for advancing our knowledge of comets, especially clues for understanding coma chemistry and composition.
