Inheritance of the trait «number of bolls on a plant» in intra-species and inter-species hybrids of oil flax
Authors: Tovstanovska T.G.
Published: January 2022

To accelerate the production of oil flax forms with improved indicators, it is necessary to know the nature of the genetic interaction in hybrid populations, in particular, the heritability of quantitative traits of seed productivity. Effective selection of plants is possible with a simultaneous combination of two conditions: wide phenotypic variability of the population and high heritability of the trait. For selection, genotypic variability is important, which is determined using the coefficient of heritability (H). The use of this genetic-statistical parameter makes it possible to speed up and optimize the breeding process by selecting genotypes with a new, more favorable combination of valuable traits and rejecting low-value material at the first stages of breeding. The aim of the study is to identify interspecific and intraspecific hybrid combinations with high rates of heritability, promising for the selection of plants with a large number of bolls. The research was carried out at the Institute of Oilseed Crops NAAS in 2019-2020. The material of the study was interspecies and intraspecies hybrids of oilseed flax of the second generation obtained in the system of dialle crosses of three samples of cultivated flax (L5, L6, M32/2) and two wild species (L. angustifolium, L. hispanicum). The second generation hybrids were studied in the F2 hybrid nursery in blocks according to the scheme: maternal form – forward and reverse F2 hybrid – parental form. Boll structure analysis was performed on 150 F2 hybrid plants and 20 parental plants. The coefficient of heritability (H) was determined by the formula (Ayala 1984) and subdivided according to the gradation (Ala 1976) into: high – 0,66-1,0; medium – 0,33-0,65; low – 0,00-0,32. As a result of researches it is established that at interspecies and intraspecies hybrids of the second generation the sign «number of bolls on the plant» was inherited in average and high degree (H = 0,48-0,90, 0,52-0,87 accordingly). Highlighted promising hybrid combinations with a high heritability of the number of bolls, which can be used to predict the efficiency of plant selection in early generations (F2-F3). The most valuable for selection are hybrid combinations, in which high rates of heritability rates are noted for two years of research: interspecific L. angustifolium × M32/2 – 0,79-0,83, M32/2 × L. angustifolium – 0,76-0,80, M32/2 × L. hispanicum – 0,82-0,90; intraspecific L5 × M32/2 – 0,71-0,81, M32/2 × L6 – 0,80-0,87.

Adoption and Implementation of Devolved Farm Forestry Extension Services from Kenya Forest Service to County Governments: Socio-Economic Wellbeing of Rural Communities and Experiences from Homabay County, Kenya
Authors: Ojijo Akoth Lucy , Kipkosgei Sirmah Peter , Kibiwot Matonyei Thomas
Published: January 2022

In Kenya, all forestry functions were National Government affairs until 2013 when farm forestry extension was devolved to the 47 Counties, Homabay County being one of them. However, the adoption and extent of implementation of the devolved farm forestry extension services are little known and its impact on rural livelihoods has not been effectively established as well as the implementation of the Transition Implementation Plan by the County Government of Homabay is not evident. Structured questionnaires were administered purposively to 399 respondents spread in eight Sub-Counties of Homabay to gather data on the extent of implementation of the devolved farm forestry extension services, to evaluate socio-economic effects of farm forestry extension services to rural communities and the extent of adoption of devolved farm forestry extension services. Results indicate the extent of adoption of farm forestry extension services is low with the farmers expressing that as much as it’s a devolved function, it is not an active process within the rural communities (82%). The key socio-economic factors that affect the adoption and implementation of devolved farm forestry are; farmers level of income for purchase of tree seeds (61%), market availability for tree seedlings (44%), land sizes and tenure systems (68%). The extent of implementation was influenced by County Government budget allocation and prioritization (67%), availability of qualified personnel (81%), government policies on interactions between the two levels of governments (49%) and obligation to the Transition Implementation Plan (89%). The results suggest that County Government needs to prioritize budget allocation and have adequate personnel as means to adequately implement the devolved functions and also to implement the Transition Implementation Plan as laid down by the Kenya Forest Service.
EICHMANN IS IN THE PANOPTICON: COMMENTS ON HANNAH ARENDT’S “BANALITY OF EVIL”
Authors: Fatah Shajwan Nariman
Published: January 2022

Hannah Arendt’s book “Eichmann in Jerusalem: A Report on the Banality of Evil” has led to a hot-debated argument among readers for years, in particular, the Jews. She has been criticized for describing the former Nazi officer, Adolf Eichmann, with the terms “thoughtless”, “clown”, and “banal”. However, through a close reading of the expression “banality of evil,” this paper presents the rational side of what Arendt has written about the offender, who has been responsible for murdering millions of people in the extermination camps. Many see him as guilty and extremely sinful. While others consider him as a heedless follower of fascism. This study aims to explore the invisible parts of this case – through the Jewish gazes on Eichmann during his trial which show the power relation that is depicted in Foucault’s “panopticism”, the influence of nationalism (Immanuel Kant), Ideology (Gramsci and Althusser), and obedience (Milgram’s experiment). This analysis demonstrates that Arendt has turned to philosophy and depicted Eichmann in his state of nature rather than being a German or a Nazi officer.

Published: January 2022

In this paper, the novel Si-MCM-41/SA porous hybrid membrane was prepared by in-corporating inorganic mesoporous material Si-MCM-41 into sodium alginate (SA) matrix, then cross-linking with 5% glutaraldehyde and 1.0 mol/L hydrochloric acid. Using scanning electron microscope (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and atomic force microscope (AFM), the prepared Si-MCM-41 sample and Si-MCM-41/SA porous hybrid membrane were characterized. The adsorption kinetics of the dibenzothiophene (DBT) by the Si-MCM-41/SA porous hybrid membrane was explored. Meanwhile, the effects of Si-MCM-41 content, porogen addition amount, DBT concentration, solution temperature, toluene concentration and other factors on the adsorption property of the Si-MCM-41/SA porous hybrid membrane were studied. In addition, the selectivity and reusability of the Si-MCM-41/SA porous hybrid membrane were also explored. The results show that the Si-MCM-41/SA porous hybrid membrane has excellent adsorption capacity for DBT, reaching 350.74 mg/g, which is a great improvement over the pure SA membrane. Moreover, among three sulfides of thiophene, 3-methylthiophene and DBT, the Si-MCM-41/SA porous hybrid membrane has the highest adsorption selectivity for DBT. The Si-MCM-41/SA porous hybrid membrane can be reused at least 5 times. Therefore, it can be known that the Si-MCM-41/SA porous hybrid membrane is an ideal adsorption material with practical application prospects.
Experimental Evaluation for the Catalytic Effect of Nickel in Micron Size on Magnesium Hydride
Authors: Rahmalina Dwi , Rahman Reza Abdu , Ismail Ismail
Published: January 2022

Magnesium hydride is well known as the ideal candidate for solid-state hydrogen storage and thermochemical thermal storage since both gravimetric and volumetric storage are considerably high. The main drawbacks of magnesium hydride are thermodynamic unfavorable and poor kinetic. Adding Nickel as a catalyst, which mainly incorporates mechanical modification (alloying or particle size reduction), can accelerate the reaction rate and decrease the enthalpy formation. It is hard to determine the catalytic of Nickel in magnesium hydride for the kinetic rate improvement. This study is focused on the observation of the effect of Nickel on magnesium hydride by using the market size availability of magnesium and nickel powder (74 μm for Mg and 63 μm for Ni). Mg and Ni are mixed by Ni variation (weight %) from 14%, 15%, and 16%. The characterization starts with initial hydrogenation and dehydrogenation, continues with activation and PCI measurement to obtain the kinetic characteristic of each sample. From this study, it is clear that the increase in nickel ratio will improve the rate of reaction for magnesium hydride, where the maximum storage for magnesium hydride is 4.2% by adding 16 wt% nickel.
MEDITERRANEAN AND NORTH PONTIC GREEK IMPORTS IN THE NOMADIC BURIALS OF THE LOWER VOLGA REGION AND FOOTHILLS OF SOUTH URALS OF THE 4th — FIRST THIRD OF THE 3rd CENTURY BC
Authors: Treister M. Yu.
Published: January 2022

In the Archaic period, Mediterranean and Greek North Pontic imports, rather well represented in Early Scythian burials on the Lower Don, are practically unknown in the burials of the nomads in the Lower Volga and South Urals regions.

The analysis of archaeological sources shows that in the second half of the 4th century BC imported beads and pendants made of glass, frit and amber reach the nomads of the Lower Volga and South Urals, and a little later, at the turn of the 4th and in the first third of the 3rd century BC — in addition, Greek pottery and possibly vessels made of precious metals, alabaster and onyx. Olbian bronze «borystheni» of the late 4th—3rd centuries BC also were found into the Lower Volga region.

If for the 5th and most part of the 4th century BC. imports that entered the South Urals were mainly represented by products of the Achaemenid circle, then after the fall of the Achaemenid state and the resulting geopolitical changes in the Lower Volga region and the South Urals imports began to be distributed from (via) the North Pontic region. It is worth noting that in the burials on the Manych river and in the Lower Volga region, finds of transport amphorae were combined with similar black-glazed echinus bowls, and the find of another such bowl in the South Urals suggests that they enjoyed particular popularity among the nomads, even if they did not penetrate Sarmatia within the same batch.

The above discussed observations rather convincingly support the hypothesis put forward by D. B. Shelov and I. B. Brashinskii. There are grounds reason to suggest that beads and pendants, as well as amphoras, black-glazed pottery and coins could have reached the nomads of the Lower Volga and South Urals precisely via the Elizavetovskoe settlement at the mouth of the Don: probably, beads and pendants — even through the Scythian settlement, on which various industrial complexes and shops existed, allegedly destroyed in the 340s BC, whereas amphoras, black-glazed pottery and coins — already through the so-called Bosporan colony, founded on the site of a settlement in the last quarter of the 4th century BC, which existed until the mid-70s of the 3rd century BC.
HORSE BRIDLE DECORATIONS FROM TOVSTA MOHYLA KURGAN: SEARCHING FOR REGULARITIES
Authors: Polidovych Yu. B.
Published: January 2022

The paper is devoted to the analysis of horse bridles from Tovsta Mohyla kurgan of the 4th century BC. The barrow was excavated by the expedition of Ukrainian Institute of Archaeology headed by Boris Mozolevsky in the Dnepropetrovsk oblast, Ukraine, in 1971. In this kurgan the burial of noble warrior and two horse graves with skeletons of 6 horses were found. The horses had bridles decorated with images of various animals and fantastic creatures. One bridle was decorated with the images of mythological characters: the serpentine goddess (Rankenfrau, probable Scythian goddess Api) and two Scythian gods who were portrayed as the Greek gods Hercules and Dionysus. All bridles have analogies in other Scythian assemblages of the 4th century BC. It has been suggested that the reproduction of certain images is associated with ideas about the path of the deceased to the Ancestor’s World. The bridles were decorated with images of fantastic animals and were a kind of mask. According to the Scythian beliefs such a bridle-mask helped to endow the horse with special properties so that it could overcome obstacles on the way to the Ancestor’s World. Probably, the serpentine goddess (Rankenfrau) was the mistress of this Ancestor’s World. On the way to the Ancestor’s World the noble warrior was accompanied by his assistant, marked by archaeologists as «groom No. 3». Such a scene is depicted in the crypt of Anfesterii from Panticapaeum on the Bosporus (modern Kerch, Crimea). It depicts the arrival of the deceased on horseback, accompanied by assistant, to the goddess, mistress of the Ancestor’s World. Further research on this topic will extend our understanding of the Scythian ideas about the Beyond.

Published: January 2022

The covid-19 pandemic caused countries around the globe to take measures, and to construct a specific set of language to talk about the virus. The present discussion paper aims to unpack this language based on Pierre Bourdieu’s theory of ‘symbolic power’, and social observations. The analysis indicates that the covid-19 field was formulated where an official language was produced, including scientific, war, enforcement and censorship linguistic practices. The paper discusses why there is not one covid-19 field and linguistic practice, causing a diversity of understanding the pandemic. The paper opens new directions in studies of language on public health threats.

Authors: Vojtěšková Jana
Published: January 2022

The article deals with the oldest music-related documents from the Morawetz collection (most of which come from the collection of Friedrich Donebauer), which the Czech Museum of Music obtained in 2003 and 2008. Specifically, this involves letters of musicians from Bohemia who were working in German-speaking countries around the end of the 18th century and the beginning of the 19th (Jiří Antonín Benda, Leopold Koželuh, Antonín František Bečvařovský, and Jan Václav Hugo Voříšek). The study presents a critical edition of six letters and one receipt and their translations into Czech and English. On that basis, there is an examination of context within the framework of the lives of the individual musicians and of the period musical milieu. The letters document cultural exchange, tastes, and the stylistic orientation of the period as well as of the music business in Europe at the end of the 18th century and the beginning of the 19th. Voříšek’s letter documents the period reception of a Mass by Jan Václav Tomášek in Vienna in 1815.

Mineralogical and geochemical variations across three basaltic lava flows from the Faeroe Islands
Authors: Jensen Aage
Published: January 2022

Three basaltic lava flows from the Faeroe Islands, one from the lower, one from the middle and one from the upper lava series, have been sampled with a maximum vertical separation between samples of 2 m, and with two parallel sample profiles for each flow.
The investigations based on this close sampling have shown that significant mineralogical and chemical variations are to be found within single extrusive bodies.
On the basis of 97 chemical analyses, microscopic investigations comprising modal analyses and deter­mination of the oxidation stages of the Fe-Ti-oxides, and electron microprobe analyses of plagioclase, pyroxenes and Fe-Ti-oxides, the mineralogical and geochemical variations across the flows are described.
Only averages of the chemical analyses for each flow are presented, but the results of all the 97 analyses can be seen in the figures, which give the variations across the flows for the main oxides, except P2O5 which hardly varies.
In a TiO,-K20-P2O5 diagram the samples from the flows from the lower and upper series fall in the oceanic field, whereas the samples from the flow from the middle series cross the border between the oceanic and non-oceanic fields.
In a F1-F2 diagram the samples from the lower and upper series fall in the within-plate basalts field, whereas the samples from the middle series fall in the field common to calc-alkali basalts and low­potassium tholeiites. In a F,-F3 diagram the samples from the middle series fall mainly in the field of low-potassium tholeiites; the contact samples fall in the middle of this field, while most of the other samples trend towards the field of ocean-floor basalts, and two samples from the middle of the flow actually reach the field of ocean-floor basalts.
Plotted in a total alkalies versus silica diagram the samples all fall in the tholeiitic field well below the dividing line of Macdonald & Katsura ( 1964 ).
The variations in the flows from the lower and middle series are interpreted as being due mainly to pre-eruptional processes whereas the variations in the flow from the upper series are believed to be due entirely to post-eruptional processes.

To fully understand the causes and mechanisms involved in overeating and obesity, measures of both cognitive and physiological determinants of eating behavior need to be integrated. Effectively synchronizing behavioral measures such as meal micro-structure (e.g., eating speed), cognitive processing of sensory stimuli, and metabolic parameters, can be complex. However, this step is central to understanding the impact of food interventions on body weight. In this paper, we provide an overview of the existing gaps in eating behavior research and describe the development and validation of a new methodological platform to address some of these issues. As part of a controlled trial, 76 men and women self-served and consumed food from a buffet, using a portion-control plate with visual stimuli for appropriate amounts of main food groups, or a conventional plate, on two different days, in a random order. In both sessions participants completed behavioral and cognitive tests using a novel methodological platform that measured gaze movement (as a proxy for visual attention), eating rate and bite size, memory for portion sizes, subjective appetite and portion-size perceptions. In a sub-sample of women, hormonal secretion in response to the meal was also measured. The novel platform showed a significant improvement in meal micro-structure measures from published data (13 vs. 33% failure rate) and high comparability between an automated gaze mapping protocol vs. manual coding for eye-tracking studies involving an eating test (ICC between methods 0.85; 90% CI 0.74, 0.92). This trial was registered at Clinical Trials.gov with Identifier NCT03610776.
A comprehensive review on electrospun nanohybrid membranes for wastewater treatment
Authors: Kumarage Senuri , Munaweera Imalka , Kottegoda Nilwala
Published: January 2022

Electrospinning, being a versatile and straightforward method to produce nanofiber membranes, has shown significant advancement in recent years. On account of the unique properties such as high surface area, high porosity, mechanical strength, and controllable surface morphologies, electrospun nanofiber membranes have been found to have a great potential in many disciplines. Pure electrospun fiber mats modified with different techniques of surface modification and additive incorporation have exhibited enhanced properties compared to traditional membranes and are even better than the as-prepared electrospun membranes. In this review, we have summarized recently developed electrospun nanohybrids fabricated by the incorporation of functional specific nanosized additives to be used in various water remediation membrane techniques. The adsorption, filtration, photocatalytic, and bactericidal capabilities of the hybrid membranes in removing common major water pollutants such as metal ions, dyes, oils, and biological pollutants have been discussed. Finally, an outlook on the future research pathways to fill the gaps existing in water remediation have been suggested.

Authors: Mugiarti Mugiarti , Adawiyah Wiwiek Rabiatul , Rahab Rahab
Published: January 2022

This study examines Ajzen’s extended Theory of Planned Behavior (TPB) framework and predicts young customers’ green hotel visit intentions. The proposed model fit was scrutinized using Smart-PLS on primary source data from 219 respondents. The results show that ecological concern is an important predictor of attitude, subjective norms, and perceived behavioral control. According to empirical findings, the green hotel image significantly moderates the relationship between TPB and visit intention. The findings support the extended TPB framework in predicting young consumers’ intention to visit green hotels in the context of young Indonesian consumers, as it has amplified the conceptual model’s predictive power. This study plays an essential role in expanding the perception of green hotel image as a critical factor in young consumer visit intention through a rigorous conceptual model and empirical research.

Oman Vision 2040 has a specific emphasis on entrepreneurship development. High quality of entrepreneurial activities, at present generates positive impact on nationals and subsequently determines an improvement on the business environment. The strategy has laid the development of the new enterprise in its priorities to diversify the national economy and reduce its heavy reliance on oil that is witnessing greater price volatility in the global market. The study attempts to assess entrepreneurial intentions among Omanis in relation to independent variable such as personal attitude, professional attraction, subjective norms, and perceived behavior control. A structured questionnaire was used to collect data from 174 young Omanis from the Sultanate of Oman and was analyzed with Chi Square, Pearson Correlation Test, Spearman Correlation Test and Multiple Linear Regression. However, it is revealed that the regression model is a good fit of the data. There is an increase, and interest amongst the Omanis with respect to entrepreneurship and innovation. The study shall recommend that the focus of government programs should be supporting new entrepreneurs to reach out to global markets, and to extend support to accelerate small business, support, and sustain them. The government should realize the aspirant entrepreneur ambitions to develop a holistic strategy with very clear pathways, outputs, KPIs, and collaborate with other SME ecosystem and key stakeholders to achieve Oman Vision 2040 goals.

The aim of this study is to determine the animal product consumption habits of associate degree students at Amasya University Suluova Vocational School. For this purpose, a face-to-face survey was conducted with a total of 285 students, which 159 students from the Veterinary Department and 126 students from the Property Protection and Security Department, between January and March 2020. When the opinions of the students about the food groups were evaluated, it was observed that 71.2% of them thought that the animal-based foods were healthier and 94.7% thought that the products of animal origin had a better protein quality. Furthermore, it was determined that the majority of the students (42.5%) were consuming foods of animal origin because they were healthy. When the animal-based food consumption frequency of the participants was examined, it was seen that those who consumed cheese (37.9%) and eggs (31.2%) every day were in the majority. While most of the participants consumed yoghurt (25.8%), ayran (26.4%), chicken meat (26.3%) and sausage (28.4%) 1-2 times a week, it was found that consumption of beef-veal (30.2%), lamb-mutton (39.6%), fish (48.8%), salami (21.4%) and sausage (29.5%) was rare. Moreover, 25.8% of the participants did not consume butter, 72.3% did not consume turkey meat and 51.9% did not consume pastrami at all. It was found that the majority of university students did not consider any of the criteria of taste, price, brand, quality, hygiene, ease of preparation, smell-color and personal health when buying red and white meat. Finally, when the participants were examined in terms of their milk consumption preferences, it was seen that the majority (47.4%) preferred street milk.

A Search for Planet Nine using the Zwicky Transient Facility Public Archive
Authors: Brown Michael E. , Batygin Konstantin
Published: January 2022

Recent estimates of the characteristics of Planet Nine have suggested that it could be closer than originally assumed. Such a Planet Nine would also be brighter than originally assumed, suggesting the possibility that it has already been observed in wide-field moderate-depth surveys. We search for Planet Nine in the Zwicky Transient Facility public archive and find no candidates. Using known asteroids to calculate the magnitude limit of the survey, we find that we should have detected Planet Nine throughout most of the northern portion of its predicted orbit—including within the galactic plane—to a 95% detection efficiency of approximately V = 20.5. To aid in understanding detection limits for this and future analyses, we present a full-sky synthetic Planet Nine population drawn from a statistical sampling of predicted Planet Nine orbits. We use this reference population to estimate that this survey rules out 56% of predicted Planet Nine phase space, and we demonstrate how future analyses can use the same synthetic population to continue to constrain the amount of parameter space effectively searched for Planet Nine.

Exoplanet systems with multiple transiting planets are natural laboratories for testing planetary astrophysics. One such system is HD 191939 (TOI 1339), a bright (V = 9) and Sun-like (G9V) star, which TESS found to host three transiting planets (b, c, and d). The planets have periods of 9, 29, and 38 days each with similar sizes from 3 to 3.4 R
⊕. To further characterize the system, we measured the radial velocity (RV) of HD 191939 over 415 days with Keck/HIRES and APF/Levy. We find that M

b
= 10.4 ± 0.9 M
⊕ and M

c
= 7.2 ± 1.4 M
⊕, which are low compared to most known planets of comparable radii. The RVs yield only an upper limit on M

d
(<5.8 M
⊕ at 2σ). The RVs further reveal a fourth planet (e) with a minimum mass of 0.34 ± 0.01 M
Jup and an orbital period of 101.4 ± 0.4 days. Despite its nontransiting geometry, secular interactions between planet e and the inner transiting planets indicate that planet e is coplanar with the transiting planets (Δi < 10°). We identify a second high-mass planet (f) with 95% confidence intervals on mass between 2 and 11 M
Jup and period between 1700 and 7200 days, based on a joint analysis of RVs and astrometry from Gaia and Hipparcos. As a bright star hosting multiple planets with well-measured masses, HD 191939 presents many options for comparative planetary astronomy, including characterization with JWST.

Current neutrino detectors will observe hundreds to thousands of neutrinos from Galactic supernovae, and future detectors will increase this yield by an order of magnitude or more. With such a data set comes the potential for a huge increase in our understanding of the explosions of massive stars, nuclear physics under extreme conditions, and the properties of the neutrino. However, there is currently a large gap between supernova simulations and the corresponding signals in neutrino detectors, which will make any comparison between theory and observation very difficult. SNEWPY is an open-source software package that bridges this gap. The SNEWPY code can interface with supernova simulation data to generate from the model either a time series of neutrino spectral fluences at Earth, or the total time-integrated spectral fluence. Data from several hundred simulations of core-collapse, thermonuclear, and pair-instability supernovae is included in the package. This output may then be used by an event generator such as sntools or an event rate calculator such as the SuperNova Observatories with General Long Baseline Experiment Simulator (SNOwGLoBES). Additional routines in the SNEWPY package automate the processing of the generated data through the SNOwGLoBES software and collate its output into the observable channels of each detector. In this paper we describe the contents of the package, the physics behind SNEWPY, the organization of the code, and provide examples of how to make use of its capabilities.
