Published: January 2023

Soil degradation is one of the common types of which is soil salination, is a serious limited factor of food security and sustainable territory development. It is necessary to pay a special attention on the first soil salination of arid regions, as arid climate leads to the active salt accumulation in the upper rooting soil horizons and gives rise to withdrawal of large land areas from economic turnover. The purpose of the this work is defining of the watersoluble salts specific features in soils of the river Volga delta upper level natural boundaries under the influence of natural factors. Botanic natural sanctuary “Svinoroiny meadow (Meshkovsky)” was chosen as a research object, associated with the new Caspian coastal plain within distribution of the river Volga delta Baer knoll landscape. Water extract ions analysis and soil solution toxicity calculation on the area were carried out from 1979 till 2020. It was revealed that dynamics direction of salination types are defined by the ascent of water predominanceon over descending on the area in the conditions of the territory exudative water regime. Salination increase to a great extent depends on the great volumes of spring-summer floods and appropriate ground water level rise, area desalination is defined by atmospheric precipitations quantity.

Published: January 2023

A comparative analysis of classical and synchronous fluorescent methods selectivity for ecotoxicants determination of polycyclic aromatic hydrocarbons (PAHs) was carried out. PAHs sorption preconcentration from aqueous cetyltrimethylammonium bromide micellar solutions and spectra recording on a viscose matrix were used. In the case of complex environmental samples, the scope of fluorimetric analysis can be expanded by registering synchronous fluorescence spectra obtained by simultaneously scanning the excitation and emission wavelengths with a constant shift: λem - λex = Δλ = const. The composition of PAHs mixture (phenanthrene, anthracene, fluorene, pyrene) was experimentally evaluated by classical fluorescence with selective excitation and synchronous fluorescence. It was concluded that the use of synchronous spectra makes it possible to improve the selectivity of the PAHs fluorescence analysis in a mixture. These methods can be successfully applied to identify individual PAHs in monitoring of environment water bodies.

Authors: Baranova Nina M. , Loginova Daria S.
Published: January 2023

In 2015, the UN Member States took 17 Sustainable Development Goals. Innovative development and environmental protection played a significant role in them. The solution to this problem directly depends on the environmental programs adopted at the state level, competent management, development of environmental innovations and their introduction. This article considers how sustainable development programs at the oil and gas enterprises are implemented to preserve the environment on the example of PJSC Gazprom. PJSC Gazprom, following the principles of sustainable development, combines economic growth and environment preservation. In 1995, PJSC Gazprom adopted an ecological program and gradually solves the environmental problems of the corporation, country and the world. Therefore, the study of some indicators of oil and gas enterprises affecting Russian environmental ecology, on the example of Gazprom Corporation, is relevant. The proceedings of Russian and foreign scientists were analyzed; UNDP’s annual and environmental reports for 2018-2022 were studied; leading Russian oil and gas companies for 2009-2021 and their environmental activities were analyzed to conduct the study. The calculations were carried out using Rosstat (2009-2021), World Bank (2009-2021), PJSC Gazprom (2009-2021). The regression analysis and econometric modeling were carried out through MS Excel and Eviews 12. The linear and exponential models of the innovative component in the environmental protection system were built and studied. It was proved the linear model can be used to build short-term forecasts, while the exponential model turned out to be untenable. PJSC Gazprom invested 658,284 billion rubles in environmental protection and rational use of natural resources, 139,1 billion rubles in RD from 2009 to 2021. In 2021, PJSC Gazprom fulfilled all of its innovative and environmental objectives and approved Environmental Program until 2024 with an outlook for 2030. The company’s contribution to the implementation of the UN sustainable development goals and objectives amounted to 89,9 %.

Published: January 2023

Exploiting advanced technological tool is considered as one of the requirements for the field of language education in the 21st century. Sadly, the field of teaching Arabic for Specific Purposes (ASP) is still a little behind when it comes to integrating these new educational tools into the teaching and learning processes. This will consequently result in decreasing the students’ motivation, as teachers still apply traditional teaching and learning methods, with a basic use of technology. It is important to note that the students in this generation utilize technology in their daily life, thus integrating these technologies in learning Arabic for Specific Purposes will benefit them in numerous aspects. Consequently, this study suggests the importance of developing learning materials using augmented reality technology for ASP modules. This study will shed a light on the concept of development, learning materials, and augmented reality. Finally, it will discuss about possible ways to develop ASP modules using augmented reality technology. It is hoped that this study will lead to advancement of educational tools for the field of ASP in the future.
A Mini Review On the Analytical Methods for Individual and Drug Combinations Administered in Mass Drug Administration for Lymphatic Filariasis
Authors: Bajaj Mohini , Nanda Sanju
Published: January 2023

Abstract: The NTDs (Neglected Tropical Diseases) are the group of diseases considered the diseases of the poor. Lymphatic Filariae (LF) is one of the category that is prevalent mostly in 47 countries and around 863 million people are under threat from this category of disease. A program named Global Programme to Eliminate Lymphatic Filariasis (GPELF) was initiated by WHO (World Health Organisation) in 1998, with the aim of eliminating LF by 2020. The main role of GPELF was to initiate measures to stop the spread of disease and to control the suffering caused by disease to the patients. For controlling the spread of disease, mass drug administration (MDA) was initiated where the drug or their combinations were administered annually or as and when required. This initiative was Alternating Mass Drug Administration Regimens to Eliminate Lymphatic Filariasis. The recommendations depended on the causative organism and co-endemicity of LF with other filarial diseases. The drug recommendations by WHO for MDA were; for areas with LF and loiasis, albendazole in a dose of 400 mg twice a year; for areas with onchocerciasis and LF, ivermectin in a dose of 200 mcg/kg along with albendazole 400 mg; for areas without onchocerciasis diethylcarbamazine citrate (DEC) in a dose of 6 mg/kg combined with albendazole in dose 400 mg. The three-drug combination was also recommended in some cases where onchocerciasis was not prevalent with LF. Many clinical trials also started for comparing one, two, and even three-drug combinations. A document to streamline the use of these drugs for LF was also issued by WHO in 2017 with the name Alternating mass drug administration regimens to eliminate lymphatic filariasis. The achievement with these regimens, till 2020 was that 80 percent of countries endemic to LF have achieved elimination of this disease. Further, to achieve better elimination in other countries a road map for 2020-2030 is now in being. The analytical methods for individual drugs as they are very old drugs were available and some of the methods for combination are also there mostly involving High- Performance Liquid Chromatography (HPLC) with different types of detecting combinations. These methods are given for detection in various clinical trials or used as an analytical method for the determination of drug(s) in dosage forms.
Fundamentos Histórico-sociais de Formação do Regime Jurídico das Florestas Nacionais em Face da Atividade Minerária
Authors: Kokke Marcelo
Published: January 2023

O regime jurídico de regulação das Florestas Nacionais e a possibilidade de exploração de recursos minerários nelas existentes proporcionam problemas e conflitos tanto em nível teórico quanto em nível prático. Esses conflitos determinam as bases de permissão ou de vedação de usos dos recursos naturais em face da proteção ambiental. A partir da metodologia analítica e da reconstrução normativa, propõe-se a compreensão do regime normativo das Florestas Nacionais com base em elementos históricos e sociológicos. O processo de elaboração da Política Nacional de Unidades de Conservação no Brasil requer a reconstrução compreensiva de suas bases normativas em um sequencial processo histórico de formação da hermenêutica regulatória. É possível nesse desenvolvimento identificar modelos regulatórios diversos no Brasil e concluir pela não existência de uma vedação a priori de atividade minerária em Florestas Nacionais. A análise de viabilidade ambiental somente pode ser feita de acordo com o caso concreto. O marco regulatório brasileiro permite, se seguido o regular processo de licenciamento ambiental, o uso dos recursos minerários que existam em Florestas Nacionais.

(Re)Framing the Historiography of the Hiatus
Authors: Silva Henriques Fabrício da , Coelho Santos Gabriela , Chaves de Freitas Lucas Daniel
Published: January 2023

The book “Cold War and International law” represents a great effort in presenting a different view in the historiography of international law about this important period of the 20th Century. The purpose of this paper is to engage with the proposal of the editors and reflect upon the issues arising from the traditional portray of the “Cold War”, although offering what could be a fourth perspective on the subject: that of the establishment of “development” as an argumentative pattern in international law. In a dialog with another recent work with special relevance to the history of International Law – Ntina Tzouvala’s “Capitalism as Civilisation” – we revisit some of the essays presented in the book to illustrate the thesis that an attention to the uses of the concept of “development” can be central to an account of this period that goes beyond the East-West feud, leaving a profound legacy in contemporary accounts of Law. By shedding light on perspectives once overlooked, the book shows how the Cold War can be analyzed as a moment of prolific development of standards of domination. The struggle for the Global South was much more than a dispute for military sway or political influence through international institutions, it also encompassed a refined project of creating concepts and a new perspective in international law that permitted the consolidation of political asymmetry through juridical institutions.

Ambiguity Function Analysis of Iridium L band signal for Opportunistic Navigation
Authors: Chen Xiao , wu zhongwang , Li Yaping , Luo Ruidan
Published: January 2023

The objective of this work is to investigate the Iridium L-band downlink
burst signal in terms of the cross-ambiguity characterization for single
burst and multicarrier multi-burst mode, to demonstrate its suitability
and capability as Signal of OPportunity (SoOP) for navigation. The
Iridium bursts are collected and examined by demodulating without any
prior knowledge for frame verification. Then, the ambiguity function
(AF) for the two modes is investigated and deduced to assess the
waveform properties with resolution and sidelobes in both the Doppler
and delay domains. It has been found that, the simplex burst with
maximum length of 20.32ms presents 40μs delay resolution and 49Hz
Doppler resolution, and its AF yields a peak to interference floor ratio
of 26.64dB, which are the best capability for the single burst mode. The
multichannel multi-burst mode produces a significant improvement for the
time delay resolution even if the AF profile degradation should be
accepted. Issues relating to the AF property improvement also are
identified during this study.
Climate related phase transitions with moving boundaries by virtue of mushy zone investigation in Al-Cu: experiment and phase-field modeling
Authors: Nizovtseva Irina , Ankudinov Vladimir , Rahner Eric , Lippmann Stephanie
Published: January 2023

Studying Arctic ice formation stays in the focus of research groups over
the past decades in the context of ice cover changes, thermal budget and
climate agenda in general. Nevertheless, the phenomenon’s underlying
mechanisms are still not completely understood and described. The main
reason for the lack in understanding is the limited experimental access
to the field data, thus there is a need to build competent analogies
between the natural (ocean water – ice) and laboratory (binary alloy)
conditions of the experiment as a step of data preparation for the
verification of the mathematical model. In the current paper the
existing qualitative models describing the process of melting and
crystallization were expanded and the experimental method was developed
copying the layering of the natural ocean water – ice mixture. The
experimental set-up for studying the solidification within the
intermediate zone was designed for Al-Cu alloys and the corresponding
experimental data was used for the development of a binary phase-field
model for solidification considering moving boundaries. The model
includes the description of the free energy of both phases and their
respective diffusion coefficients. It allows modeling of the eutectic
alloys and potentially corresponding natural ocean water — ice mixture
at a mesoscopic spatial level by including the concentration-driven
phase transition. The novel results will help the quantitative
understanding of solidification phenomena and are highly-evaluated from
interdisciplinary point of view, including glaciology and geosciences,
ultimately significant for the understanding the global climate change
landscape.

Hyperbilirubinemia Predisposes to the Incidence of Nosocomial Infection in Egyptian Patients with Cirrhosis: A cohort Study
Authors: ahmed khadija , Mostafa Tarek , elhaggar sahar , abdelsalam sherief
Published: January 2023

Background: nosocomial infection (NIs) is a major challenge in
healthcare facilities and has been associated with prolonged hospital
stay as well as increased morbidity and mortality. Aims: This research
aimed to estimate the impact of acute decompensation (AD) consequences
on the successive risk of nosocomial infections (NIs) and the go after
outcome. Methods: A total of 250 hospitalized cirrhotic patients with
decompensation were included in the study. Different decompensation
events and after-effects in patients with or without NIs were compared.
The logistic regression and Cox proportional hazards models were
designed for NIs development and mortality at 28 days, respectively.
Results: During hospitalization, 22.4 % of patients developed NIs.
Remarkably, a higher percentage of patients with NIs had jaundice
(42.9% vs. 26.8 %; p= 0.06 at admission compared to patients without
NIs, whilst a lower percentage had gastrointestinal hemorrhage (14.3 vs.
33.5%; p=0.017+). Multivariate analysis revealed that jaundice was
independently linked with the development of NIs (OR, 0.474; 95% CI:
0.24–0.92). The 28-day mortality rates of patients with NIs were
significantly higher than those without NIs (21.4 vs. 9%; p = 0.014).
According to the Cox proportional hazards model, jaundice stayed an
independent risk factor for 28-day death (HR,8.38; 95% CI:
3.58–19.62). Conclusion: Different decompensation events have different
impact on the incidence of Nosocomial infections. Jaundice is
independently associated with occurrence of NIs and increased 28-day
mortality. Therefore, prophylaxis measures are recommended to benefit
this specific subsection of patients. Keywords Decompensation,

counting annuli formed in the cementum of teeth. This method has been
used in bears despite some disadvantages, such as high invasiveness and
the requirement for experienced observers. In this study, we established
a novel age estimation method based on DNA methylation levels using
blood collected from 49 brown bears of known ages living in both
captivity and the wild. We performed bisulfite pyrosequencing and
obtained methylation levels at 39 cytosine-phosphate-guanine (CpG) sites
adjacent to 12 genes. The methylation levels of CpGs adjacent to four
genes showed a significant correlation with age. The best model was
based on DNA methylation levels at just four CpG sites adjacent to a
single gene, SLC12A5, and it had high accuracy with a mean absolute
error of 1.3 years and median absolute error of 1.0 year after
leave-one-out cross-validation. This model represents the first
epigenetic method of age estimation in brown bears, which provides
benefits over tooth-based methods, including high accuracy, less
invasiveness, and a simple procedure. Our model has the potential for
application to other bear species, which will greatly improve ecological
research, conservation, and management.

Gut microbiome gene catalogues have advanced the knowledge of
host-microbiome interactions in many mammals. Snub-nosed monkeys
(Rhinopithecus spp) are folivores with foregut fermentation which is
similar to ruminants, but their gut microbiota lacks a comprehensive
description. In this study, we constructed a comprehensive gene
catalogue by performing metagenomic analysis on 143 wild snub-nosed
monkeys and compare it to that of ruminants and monogastric animals. Our
results demonstrate the classification and functional characteristics of
the gut microbiome of snub-nosed monkeys and identified a set of core
genera in these mammals. Moreover, we found that the gut of snub-nosed
monkeys and other herbivores was enriched with more bacteria and enzymes
related to the degradation of structural carbohydrates, indicating the
importance of gut microbiota for dietary adaptation. Our study expands
resources for gut microbiome studies of nonhuman primates and provide
new insights into the evolutionary route of foregut fermenting animals
during dietary adaptation.
Vukovarsko vlastelinstvo – slavonsko-srijemski

Premda se autori u radu osvrću na sve komorske popise do sredine 18. stoljeća (popisi iz 1698., 1722., 1728., 1736. i 1749.), kao i na kartografiju koja je prethodila najvažnijem kartografskom izvoru, dovršenom 1733. u formi atlasa, usredotočuju se na analizu komorskoga popisa iz 1728. i navedeni atlas kao izvore iz približno istoga vremena, obilježenog transformacijom jednoga velikog područja iz državnoga vlasništva (komorskoga okruga) u privatno vlasništvo (vlastelinstvo). Na osnovi tih izvora, koji se dopunjavaju, nastoje dati širu sliku stanja jednoga slavonsko-srijemskoga vlastelinskoga gospodarstva prve polovine 18. stoljeća u trenutku njegova stvaranja, tim više što zbog nepostojanja odgovarajućih kartografskih izvora to nije moguće ni za jedno drugo vlastelinstvo. Osim osnovnih podataka kao što su broj i veličina naselja, zastupljenost pojedinih kategorija zemljišnih površina, demografsko i imovinsko stanje i sl., analizom i usporedbom također se nastoji utvrditi relevantnost i vjerodostojnost obaju izvora te podudarnost i različitost sadržaja primjenom deskriptivnih i kvantitativnih metoda.

Published: January 2023

In order to evaluate the effect of raw meat's freezing/thawing process on
meat products produced from them, frankfurter's quality was monitored. Fresh
beef meat was grounded and separated into two lots - the first lot was
immediately used in the preparation of frankfurters (G1F), and the other lot
was frozen and stored at -18?C for 4 weeks, when it was used in the
preparation of the second group of frankfurters (G2F). Physicochemical and
technological properties were investigated on fresh (CG-FM) and thawed meat
(G-F/TM) samples and the frankfurters made from these samples. Frozen
storage significantly affected (p<0.05) moisture, TBA value, instrumental
color parameters (L*a*b*), WHC, total pigment, and total heme pigment in the
raw meat samples; some frankfurters characteristics, such as moisture,
L*(lightness), a* (redness) and b* (yellowness) were affected (p<0.05).
However, the differences in the final products' process loss/cooking
loss/frying loss and FRP were not significant. The sensory evaluation did
not show any significance between the two groups of frankfurters It can be
concluded that the frozen storage of minced beef meat for 4 weeks at -18?C
and the consequential thawing process (at 4?C for 24h) does not
significantly affect the overall acceptability of frankfurters prepared from
them. However, effects on the marked changes in instrumental color are
apparent.
The long road to equality: University and gender in Argentina
Authors: Rulli Mariana
Published: January 2023

In the first decades of the 20th century in Argentina, especially in 1918,
there was a university reform promoted by the student movement and that
promoted the democratization of the universities. However, the massive
incorporation of women into the country?s national universities is going to
arrive almost around the end of the century. Thus, in the first decades of
the 21st century, several reforms were produced in most of the Argentine
universities, which were promoted by the feminist movement, the women
professors and researchers, the students and the administrative workers. The
main reforms were the enactment of protocols in cases of violence and / or
discrimination based on gender, the creation of gender areas in the
administrative and organizational structures of the universities, and the
inclusion of parity for the selection of authorities. In this chapter, the
latest feminist transformations and reforms in Argentine national
universities will be analyzed based on three key areas: (i) violence and
discrimination based on gender, (ii) processes of institutionalization of
gender areas, and (iii) inclusion of parity for the selection of
authorities. Likewise, there will be a brief description of the main
inequalities at the university level such as horizontal and vertical
segmentation.
She wears a nylon underskirt and raffia opanci shoes: Women’s costume narratives in the caricatures of “Jez” newspaper
Authors: Mikulic Tatjana
Published: January 2023

During the 20th century, the representation of the stock female character in the caricatures of the newspaper ?Jez? underwent a significant transformation: while in the 1930s the character of the peasant woman was reduced to a simple graphic form, rough and without details, an attractive peasant woman appeared in the mid-20th century, primarily in drawings by Desa Glisic, with a short skirt, narrow waist and enlarged bust. However, in accordance to the traditional cultural norms, she was still dressed in folk costume. Broadly speaking, Desa?s female characters paraphrased the craze for novelties from shops in Belgrade which retailed imported costume items. This visualization of women through the synergy of traditional and modern, or more precisely clothing and fashion, proved to be a convenient platform for interpreting the potential objectification of women (Fredrickson & Roberts). At the same time, we are going to determine whether the mentioned depiction of a rural woman endangered the hitherto dominant patriarchal pattern of visualizing women, when their function as a symbol of traditional values through the role of mother and housewife underwent transformation.
The effect of fluid dynamics conditions and combustion reactions on the performance and heat and mass transfer distribution of dual-phase oxygen transport membranes

Published: January 2023

A 3-D model based on CFD approach was developed to explore the effect of fluid dynamic conditions and combustion reactions on oxygen transport, in which the distribution of parameters such as oxygen partial pressure, temperature, velocity, and oxygen permeability were considered. After meshing the geometric model with poly-hexcore method, a series of user defined functions written in C++ were compiled and hooked to FLUENT to solve for oxygen permeation of dual-phase oxygen transport membranes. The results showed that oxygen permeability can be improved by pressurizing the feed side or vacuuming the permeate side, and the increased kinetic effect under evacuation conditions can increase the oxygen permeability by 69.85% at a vacuum pressure of 10 kPa and by 270.94% at 90 kPa. Due to the phenomenon of differential concentration polarization, the effect of oxygen concentration on oxygen permeability is more significant when the oxygen concentration on the feed side is lower than 0.17. Combustion reaction of CH4 promotes oxygen permeation, and the effect of the gap height between the fuel inlet and membrane is determined by several trade-off factors including momentum effects, reaction rate and temperature, and optimal oxygen permeability is achieved with a gap height of 3 mm.

Published: January 2023

In the present work, we investigated polycyclic aromatic hydrocarbons, metals and ions of indoor and outdoor PM2.5 from 80 samples collected in the microenvironment of a kindergarten located in Belgrade city center during weekdays, from March to May 2010. The daily concentrations of PM2.5 were much higher than WHO guidance daily value. Results show similar factor profiles identified by principal component analysis (PCA) and positive matrix factorization (PMF). For indoor and outdoor environment, six principal components were identified by PCA, and six and seven factors were identified by PMF, respectively. Principal components from PCA were attributed to the following sources: combustion processes, traffic emission, coal/oil combustion, mix (stationary sources/resuspension), road salt and secondary aerosol. The resulting factors from PMF were identified as representing combustion processes, traffic emission, coal/oil combustion, soil dust, secondary aerosol and break wear. For outdoor environment, PMF identified one more source, attributed to road dust.

OBJECTIVE

To compare postpartum glucose tolerance between women treated for gestational diabetes mellitus (GDM) and those not treated.

RESEARCH DESIGN AND METHODS

Metabolic testing was performed at 3 and 12 months postpartum in 599 women comprising the following gestational glucose tolerance groups: 1) normal glucose challenge test (GCT) and oral glucose tolerance test (OGTT) during pregnancy, 2) abnormal GCT with normal OGTT, 3) gestational impaired glucose tolerance, 4) mild untreated GDM, and 5) severe treated GDM.

RESULTS

Birth weight progressively increased across groups 1–4 before falling steeply in treated GDM (P < 0.0001). In contrast, at 3 and 12 months, insulin sensitivity and β-cell function progressively decreased across the five groups, mirrored by rising fasting and 2-h glucose (all P < 0.0001). Accordingly, prevalence of prediabetes/diabetes at 12 months increased in a stepwise manner across groups 1–5 (2.8%, 9.6%, 13.5%, 21.5%, and 32.6%, respectively; P < 0.0001).

CONCLUSIONS

Treating GDM lowers birth weight but does not disrupt the association between gestational glycemia and maternal prediabetes/diabetes after pregnancy.
