Public Property Management in Russian Federation: Basic Principles (Part 1)
Authors: Shulzhenko S. I.
Published: August 2021

The paper deals with problems of legal status of state (municipal) bodies and government (municipal) agencies as legal entities in the context of modern Russian treasury budget execution system and underlines the absence of the necessity for their legal entity. Within the framework of budget system reform, the paper regards the right of operational management and the right of permanent perpetual use for the state (municipal) bodies and government (municipal) agencies as anachronism, inherited from the Soviet law, and unnecessary. At the same time the author insists on merging into one institution the right of operational management and the right of permanent perpetual use for budget organizations and autonomous institutions as legal entities and proposes changes to the current legislation.

Authors: Qutub Afnan , Marie Dina , Meer Samar , Alkurdi Amira
Published: August 2021

This study examines the Netflix Spanish series La Casa de Papel as a pragmatic example of a series that addresses questions of criminal justification. In this qualitative study, in-depth interviews were conducted with 17 Saudi participants. The findings suggest that the Saudi viewers justified the characters’ crimes influenced by fundamental attribution error. Viewers’ identification with the characters could be seen in their empathy with the robbery team and their desire for threatening characters to die. Viewers also stated that they did not want the criminals to be caught. In fact, viewers felt sad and emotional when the characters were shot or caught. Participants ranked the Professor, Tokyo, Berlin, and Nairobi as the most liked characters. Conversely, the least liked characters were Arturo Román and Sierra because they threatened the success of the robbery. Finally, participants accepted the banker joining the team, while they opposed detective Lisbon joining it.

Authors: Dimitrov Evgeniy , Uhr Zlatina , Velcheva Nikolaya
Published: August 2021

The study was conducted during the period 2017-2019 in the experimental field
of IPGR Sadovo. Wheat is the most important agricultural crop worldwide.
Bulgarian wheat production in 2019 amounts to 6.162 thousand tons - an
increase of 5.7% compared to 2018, due to the relatively favorable climatic
conditions in the process of crop development, which led to an increase in
average yield (with 6.8%). Twenty nine common winter wheat varieties
(Triticum aestivum L.) with Belorusian origin and two Bulgarian varieties -
Sadovo 1 and Enola were evaluated. The studied materials were sown in 2 rows
with the length - 2 m, at the row spacing - 20 cm and the distance in rows -
5 cm. The standard technology adopted in IPGR for cultivation of common
winter wheat was used. The aim of this study is to investigate the genetic
distance of common winter wheat genotypes with a view to their use in the
breeding process as sources of initial material for the formation of new and
highly productive wheat varieties. Biometric measurements were made on 20
plants of each genotype and the main productivity indicators were recorded.
To evaluate the genetic similarity between the different varieties, cluster
analysis and PC analysis were applied. Based on the cluster analysis, the
studied genotypes are classified into five large cluster groups. With the
most genetic closeness to each other are characterized the varieties
Vasilisa and Uzlet, followed by Daria and Rostan. The greatest genetic
distance is shown between the Bulgarian varieties Sadovo 1 and Enola to the
varieties from Belarus. The greatest genetic difference was found between
Sadovo 1 and Rassvet, followed by Enola and Rassvet. Genetically distant
varieties belonging to different cluster groups can be used as sources of
initial material to achieve genetic diversity in the breeding of common
winter wheat.

Published: August 2021

The aim of this study was to determine the level and variability of type
traits in primiparous Holstein-Friesian cows, as well as to assess the
additive genetic variance of type traits and heritability coefficients. The
research was conducted on a data set of linearly evaluated primiparous
Holstein-Friesian cows, which is ceded by the Main dairy cattle breed
organization in the Province of Vojvodina, which is a unit of the Department
of Animal Science, at the Faculty of Agriculture in Novi Sad. Data of 24226
primiparous Holstein-Friesian cows, refer to the period 2012-2015, were
analysed. The phenotypic variability of the type traits, as well as effects
of systemic factors affecting these traits, were analyzed using standard
statistical methods in the Statistica software 13.2, and the general linear
model (GLM). A Statistically highly significant effect for most of the type
traits had the farm size, interaction of the year and the season of
evaluation, age at linear evaluation, lactation stage and a genetic group
formed by the year and country of bull/sires birth. The total type traits
score (final score), which represents an evaluation of the overall
primiparous cow exterior, is calculated for the 24226 linearly evaluated
primiparous cows. Estimation of variance components and heritability
coefficient calculation is done in the software package WOMBAT. Heritability
coefficient values for the primiparous cow's type traits in the Province of
Vojvodina were low to middle, ranged from 0.08 for the rear legs - side view
up to 0.38 for the stature. Due to the fact that the value of the
heritability coefficient depends on the variability of the traits and
previous selection, lower heritability may be a consequence of the low
genetic variability, or, a higher degree of variability which is a
consequence of the effect of the systematic factors. Heritability
coefficients indicate a genetic variability of the type traits, and its
evaluation is important for the breeding value estimation for the type
traits.

Authors: Ulas Firdes
Published: August 2021

In this study, different eggplant scion genotypes were grafted onto different
eggplant rootstock genotypes in order to assess the plant growth,
development, and fruit yield of eggplant plants based on the physiological
and morphological response mechanisms. The experiment was conducted at the
vegetable research field plot on the campus at Faculty of Agriculture,
University of Erciyes, Kayseri-Turkey. The field experiment was carried out
to determine plant growth, shoot and root fresh and dry biomasses, plant
height, total leaf area, leaf chlorophyll index (SPAD), rootstock and scion
stem diameter, number of fruits per plant, total fruit yield, fruit dry
matter, fruit diameter and length, total seed yield, and thousand seed
weight. Two eggplant cultivars (Topan and Pala) were grafted onto two
different eggplant rootstock genotypes (Hawk and K?ksal F1), while
non-grafted scion genotypes were used as control plants. The experiment was
laid in a randomized completely block design (RCBD) containing three
replications. The results indicated that between grafted and non-grafted
plants significant (P<0.001) differences were observed in shoot and root
fresh and dry biomasses, plant height, total leaf area, leaf chlorophyll
index (SPAD), rootstock and scion stem diameter, number of fruits per plant,
total fruit yield, fruit dry matter, fruit diameter and length, total seed
yield, and thousand seed weight. The rootstocks utilized have influenced the
vigour of the grafted plants. The ?Pala? grafted on the rootstock ?K?ksal
F1? registered 61.91% increment in shoot fresh biomass and 49.04% increment
in root fresh biomass in comparison to the non-grafted plants. Grafting
influenced plant height which reached values of roughly 1.0 m, leaf are
resulting in values of 5645.04 cm2 plant-1, and SPAD resulting in values of
47.48 at ?Pala/K?ksal F1? graft combination in comparison to the non-grafted
plants. The grafting combinations also influenced the productivity of plants
as compare to non-grafted plants. The significantly highest fruit yield
obtained from ?Pala/K?ksal F1? graft combination was of 4711.89 g plant-1,
followed by ?Topan/K?ksal F1? graft combination with 3834.54 g plant-1.
?Pala? was produced 11.49 number of fruits per plant when grafted on the
?K?ksal F1? rootstock and 8.46 number of fruits per plant when grafted on
the ?Hawk? rootstock. Regarding seed yield, ?Pala? grafted on the rootstock
?K?ksal F1? registered 72.03% increment in total seed yield in comparison to
the non-grafted plants. Overall, the eggplant rootstock genotypes ?K?ksal
F1? showed a better performance shoot and root fresh and dry biomasses,
plant height, total leaf area, leaf chlorophyll index (SPAD), rootstock and
scion stem diameter, number of fruits per plant, total fruit yield, fruit
dry matter, fruit diameter and length, total seed yield, and thousand seed

Published: August 2021

Persian hogweed (Heracleum persicum Desf. ex Fischer) is native to Iran but
was introduced to Europe as an invasive plant. It has medicinal and edible
values. Its fruits have been used to relieve flatulence, stomach aches as
well as a flavoring as a digestive and an antiseptic. This medicinal plant
forms many geographical populations in the country, particularly in
mountainous regions; however, we have no data on the genetic structure and
genetic diversity of this plant species. Such information can be used in
gene pool identification and future genetic conservation and breeding
programs. Therefore, the present study was performed with the following
aims: 1- Provide data on genetic diversity of geographical populations, 2-
Identify the potential gene pools for future genetic conservation and
breeding programs. We used both Inter-simple sequence repeats (ISSR) and the
Start Codon Targeted (SCoT) molecular markers as these are suitable
molecular markers for genetic diversity investigations. There are highly
polymorphic, reproducible, and relatively low cost markers. The present
study revealed that both ISSR and SCoT markers produce data on the genetic
variability and genetic affinity of the local populations. Both molecular
markers revealed a good level of genetic variability within and among
Heracleum persicum populations. Analysis of molecular variance (AMOVA)
produced a significant differences between geographical populations for both
markers. We could identify few ISSR as well as SCoT bands which can
differentiate the studied populations. The moderate to a good level of
genetic diversity we observed within each H. persicum may be due to cross
pollination. In conclusion, we suggest using combination of ISSR and SCoT
molecular markers to study population genetic variability in H. persicum
geographical populations for future genetic conservation and germplasm
collection of this medicinal plant.

High level learning ability (HOTS) is the ability of students to be critical and creative thinking skills. In 2013, students were required to be able to receive information and remember it, but students must be able to solve the problems they faced with the knowledge they needed. Based on observations, the instruments used by teachers are still at the level of C1-C3, while for high-level thinking abilities students must be able to think at the C4-C6 level. This study aims to analyze the ability of high-level thinking of students on material changes in the environment. The assessment instrument used is an instrument of assessment of high-level thinking ability that is valid, practical, reliable and has good quality items. The instrument is said to be valid if the instrument can measure what should be measured. The practicality of the assessment instrument depends on how easily the instrument is used to assess students' abilities. Reliable means that the instrument gives the same results when tested in the same group at different times. An instrument that has good quality items is an instrument that has a moderate level of difficulty and sufficient differentiation, good and very good. Based on the results of the test questions, the average value of students is 41.37 which is still categorized as low. The low level of students' high-level thinking skills can be improved by familiarizing students with higher-order thinking and using scientific learning models.
