There has not been much study done to explain how recent climate change affects the water surface area changes in lakes in different natural areas of Mongolia. Four lakes between 48° - 50° in Mongolia were chosen for this investigation because they have the same climatic and solar radiation patterns. The case studies of the Khoton Lake in the high mountain region, Terkhin Tsagaan in the forest-steppe region, Khukh Lake in the steppe region, and Namir (Khar Us) in the Govi region emphasized the relationship between lakes surface area and climate variables, which are temperature and precipitation. In the study, statistical analysis methods, the Mann-Kendall test (MK), the innovative trend analysis method (ITAM), the Sen's Slope Estimator Test (SET), and the normalized difference water index (NDWI) method were used. During the past 30 years, calculations based on satellite imagery of the lake area in different natural zones have shown a decreasing trend for the lake area. After 2000, all-natural regions saw a sharp rise in the long-term average air temperature. High mountain regions have seen an increase in precipitation since 2000, Forest-steppe regions have increased since 2010, and steppe and gobi regions have declined since 2000. Lake areas in the high mountain and forest-steppe regions showed a steady decreasing trend starting in 2000, while lakes in the steppe and Gobi regions showed a gradually creasing trend starting in 2010. The increase in the average annual air temperature (Z=1.17) in the high mountain region was more closely related to the changes in the lake region. On the other hand, the area in the forest-steppe zone was better correlated with the quantity of precipitation (Z=1.93). The effect of air temperature (Z=1.21) on the area of lakes in the steppe zone was more relevant, while the amount of precipitation was slightly related. Rainfall (Z=-1.80) was more related to the area of lakes in the Gobi region, while the air temperature was less related. The novelty of the research is that it has been clarified that the lake changes in the area in different natural regions are influenced differently by the climate.

Published: February 2023

The fixed dose of lercanidipine hydrochloride(LH) and enalapril maleate (EM) is used to provide more effective control of hypertension. The research work was aimed at the development and validation of simple and sensitive analytical methods for their quantification from tablets. The simultaneous equation, first-order derivative, and multivariate spectrophotometric methods were developed for the simultaneous estimation of LH and EM in tablets. The simultaneous equation method involves a determination of LH and EM at 236 nm and 207 nm, respectively. First order derivative UV spectrophotometry method involves using a zero crossing point of LH at 330 nm and EM at 219 nm. Both methods were validated as per ICH Q2 (R2) guidelines and found to be accurate and precise as they exhibited <2% relative standard deviation. The limit of detection (LOD) and limit of quantitation (LOQ) for LH were found to be 0.26 μg/ml and 0.78 μg/ml respectively whereas LOD and LOQ for EM were found to be 0.41 μg/ml and 1.24 μg/ml respectively for simultaneous equation method. The LOD and LOQ for LH were found to be 0.39 μg/ml and 1.19 μg/ml respectively whereas LOD and LOQ for EM were found to be 0.31 μg/ml and 0.97μg/ml respectively for the first-order derivative method. Three Chemometric methods namely classical least square (CLS), principal component regression (PCR), and partial least square (PLS) were studied for the simultaneous determination of LH and EM in tablets using spectrophotometry. A set of 25 standard mixtures containing both drugs were prepared in the range of 5–25 μg/ml for both drugs. The analytical figure of merit (FOM) was determined for all three chemometric methods. The LOD values for LH were found to be 0.97, 0.93, and 0.94 μg/ml and 0.90,0.88, and 0.89 μg/ml for EM using CLS, PCR, and PLS modeling techniques. The proposed methods were user-friendly, rapid, and sensitive enough for the determination of LH and EM.

Published: February 2023

CV Tirta Alam Dodu is a privately owned company engaged in the beverage industry in the form of AMDK. The problem faced by the company is that there is a difference between demand and sales, or better known as the bullwhip effect problem. The purpose of this study is to reduce the bullwhip effect on the supply chain and optimize the amount of product inventory according to the amount of demand. The method used is the Collaborative Planning, Forecasting, and Replenishment (CPFR) method. Based on the results of the research conducted, it can be concluded that the analysis of demand forecasting calculations on AMDK products at CV Tirta Alam Dodu was carried out using historical data on product demand through five analytical methods, including Linear Trend, Moving Average, Exponential Smoothing, Decomposition, and Winter's Model. The best forecasting resulted in Winter's Model which showed the smallest error value compared to the other four models. The way to minimize so that it does not become a bullwhip effect is to use the CPFR method, where the bullwhip effect value is obtained on glass mineral water products and gallons of mineral water of 0,985 and 0,898, respectively. This result shows that there is no amplification of demand and has reached the company's target, which is to fall below number one. The way to optimize inventory so that there is no excess stock or shortage of stock in the product is to make the amount of inventory based on the amount of demand from the forecasting results plus the safety stock.
La memoria audiovisual en internet. El camino del Archivo Histórico de Radio y Televisión Argentina
Authors: Rivero Ezequiel Alexander
Published: February 2023

El archivo sonoro y televisivo de los medios del Estado argentino es uno de los más antiguos y extensos del país. La Televisión Pública (Canal 7) conserva 57 mil horas de video que datan desde 1956, y Radio Nacional unas 160 mil horas de audio a partir de 1938. Desde 2007 la “cuestión del archivo” comenzó a tematizarse y desde 2009 se fueron generando condiciones de infraestructura para detener el deterioro de los soportes físicos, almacenarlos en condiciones adecuadas y digitalizarlos. El costado público del proyecto consistió en la publicación de gran volumen de material histórico en YouTube. Este aspecto fue el punto de desacuerdo entre las autoridades que condujeron el proyecto hasta 2017 y las que asumieron su coordinación en nombre de la gestión macrista. Esta última incorporó una visión más restringida del mandato legal de ofrecer “acceso universal” a los contenidos.A partir de una necesidad acuciante: preservar y democratizar uno de los mayores tesoros audiovisuales del país, RTA emprendió un desafío ambicioso tanto desde un punto de vista tecnológico, como económico y organizativo. El proyecto se vio afectado en 2015 y 2019 por el recambio de autoridades gubernamentales, lo que se tradujo en cambios en su lógica de funcionamiento, especialmente en relación a la disponibilidad de los contenidos en internet. No obstante, a quince años de su nacimiento en 2007, la iniciativa sobrevivió a varios directivos y autoridades políticas, un hecho auspicioso teniendo en cuenta el esquema de baja institucionalidad que es habitual en los medios del Estado.

Authors: Nukeshtayeva Karina , Kayupova Gaukhar , Yerdessov Nurbek , Bolatova Zhanerke , Zhamantayev Olzhas , Turmukhambetova Anar
Published: February 2023

Objective: To identify factors contributing to maternal
mortality in Kazakhstan. Design: A retrospective study of the
health and demography data set of Kazakhstan from 2000 to 2020.
Setting and population: The data from the annual statistical
report “Population health and healthcare organizations’ performance in
the Republic of Kazakhstan from 2000 to 2020”. Kazakhstan and its 14
regions and 3 main cities for the period 2019-2020. Methods: We
analyzed the MMR trend in Kazakhstan and in all 14 regions and 3 main
cities for the period 2000-2020. We applied Univariate Linear Regression
Models with Logarithmic Transformation of the outcome and predictors to
detect determinants of MMR for 2019 and 2020 in Kazakhstan. Main
Outcome Measures: Maternal mortality ratio and determinants.
Results: Trends in MMR in many regions of Kazakhstan show a
steady decline starting from 2000 until 2010-2015 with a subsequent
increase by 2020. MMR was associated with factors such as
socio-economic, health service-related, and population health
indicators. An increase in most of these indicators leads to a decrease
in maternal mortality, except obstetric beds per 1000 births, number of
inpatient facilities, and population median age, which leads to an
increase in MMR. Conclusions: Maternal mortality is a complex
issue that is influenced by various socio-economic factors, healthcare
system factors, and disease burden. Despite Kazakhstan’s alignment with
the SDG goals, including reducing maternal mortality, the country’s
middle-income status may have led to fluctuations in MMR.
Enclosing control for nonholonomic mobile agents with a moving target of unknown velocity
Authors: Wang Jing , Ju Shuang , Dou Li-Ya
Published: February 2023

In this paper, an enclosing control problem is investigated for
nonholonomic mobile agents with a moving target of unknown velocity. An
adaptive observer containing two internal variables is first designed
for each agent to compensate for the lack of the target velocity
information. One variable is designed to estimate the unknown target
velocity and further its estimation error is assessed by the other
internal variable to subsequently guarantee the control performance.
Then using the estimated information from the adaptive observer, a
dynamic control law for circular formation of nonholonomic agents around
the moving target is designed by a backstepping process. The global
asymptotical stability of the closed-loop system is achieved under the
proposed dynamic control law with the adaptive observer. Finally, a
simulation is conducted to demonstrate the effectiveness of the proposed
approach.
Lung ultrasonography results statistically agrees with computed tomography in estimates of COVID-19 pneumonia extent
Authors: Wolf Jonas Michel , Pallarés Luiz Carlos , Zanardo Ana , Souza Vinicius de
Published: February 2023

Objectives: Despite its low sensitivity for the interstitial
syndrome, chests X-Ray (XR) have been used on COVID-19 patients to
exclude alternative diagnoses. Computed tomography (CT) scans can both
exclude other pathological conditions and display a high level of
sensitivity for the COVID-19 pneumonia. We therefore decided to compare
the performance of lung ultrasonography (LUS) with that of lung CT scans
in suspect or confirmed COVID-19 patients for the presence of
interstitial pneumonia and the degree of lung injury. Methods:
In a cross-sectional clinical study, LUS an CT were compared for the
presence of interstitial pneumonia and the degree of lung injury in
COVID-19 patients. Pearson’s and Spearman correlations analysis were
performed to measure the degree of association between two methods.
Bland–Altman plot was generated to provide a graphical visualization of
the agreement between the two measurement methods. All statistical tests
in this study were two-sided and p-values ≤ 0.05 were considered
as statistically significant. Results: A good correlation
between LUS and CT scan was obtained for estimates of lung injury in
pneumonia in a group of COVID-19 suspect and diagnosed patients (R
= 0.7613; p <0.01). Agreement
between LUS and CT values is assessed by constructing Bland-Altman plot.
Conclusions: LUS, as compared to CT scans, is an effective
method to estimate degrees of lung injury in COVID-19 patients in the
emergency department.

Published: February 2023

Understanding the characteristics of long-term changes in the water use
efficiency (WUE) of grassland ecosystems is vital for WUE improvement on
the Qinghai-Tibet Plateau. In this study, five vegetation types, namely
alpine shrub, desert, grassland, meadow, and swamp, were evaluated. The
changes in WUE over the past 16 years were calculated using the total
primary productivity and latent heat flux data of the ecosystem from
2006 to 2021. In addition, meteorological data were used to further
explore the relationship between WUE and environmental factors. The WUE
of alpine desert, meadow, and swamp showed an increasing trend. In
contrast, alpine shrub and grassland WUE showed a decreasing trend, with
the WUE of shrub being significantly higher than that of grassland on
the interannual scale. The WUE of all vegetation types showed seasonal
maximum and minimum values in July and January, respectively, and the
WUE of shrubs was significantly higher than that of the other vegetation
types. The structural equation model showed that precipitation,
temperature, and relative humidity were the main positive influences on
the WUE of grasslands on the Qinghai-Tibet Plateau, whereas net
radiation had a negative influence. Climate factors may substantially
impact future changes in the WUE of various ecosystems. The results of
this study provide a theoretical basis for further study of WUE changes
in the grasslands of the Qinghai-Tibet Plateau.
Xylan Deconstruction by Environmental Bacterium Caulobacter crescentus
Authors: Bui Viet , Inkoom Rhoda , Periyannan Gopal
Published: February 2023

Bacterial species display unique and common molecular mechanisms for
nutrient acquisition depending on their habitat. Molecular details of
xylan utilization by plant pathogens and human commensal bacteria have
been reported but no significant reports can be found for environmental
bacteria. Caulobacter crescentus is a gram-negative, oligotrophic,
environmental bacterium with unique adaptations for growth in
low-nutrient conditions. C. crescentus’ genome codes for a repertoire of
genes that can facilitate xylan utilization as a carbon source for
growth. Polymeric xylan and xylan-derivative use by C. crescentus was
investigated in this work. Growth, enzyme, metabolite, and gene
expression analyses show possible membrane-bound enzymes for xylan
deconstruction on the cell surface while enzymes for further
deconstruction of xylan-derived oligosaccharides are concentrated in the
periplasm. TonB-dependent transporter (TBDT) inhibition data suggest
that TBDT may be involved in the transport of xylo-oligosaccharides
across the outer membrane. Collectively, data suggest xylan binding onto
the bacterial surface and deconstruction and the xylan fragment uptake
across the outer membrane. A comprehensive model for xylan utilization
by C. crescentus develops to show features of previously proposed gut
and plant pathogenic bacterial models. This study further advances the
molecular level understanding of xylan derived nutrient acquisition in
environmental bacteria.
A Review of Metal-Organic Framework (MOF) Materials as an Effective Photocatalyst for Degradation of Organic Pollutants
Authors: Khan M. Shahnawaz , Li Dongsheng , Qu Jianbei , Xu XuHui , Yang Hui Ying
Published: February 2023

Water plays a vital role in all aspects of life. In recent years, water
pollution has increased due to various organic and inorganic pollutants
caused by human activities. Organic pollutants are hard to degrade in
nature. Henceforth cost-effective and sustainable approaches are needed
to degrade these organic pollutants to purify wastewater. Organic dye is
a major source of organic pollutants from coloring industries, which
must be removed during water treatment. The photoactive metal-organic
frameworks (MOFs) offer an ultimate strategy to construct catalysts to
degrade pollutants present in wastewater. Tuning the metal ions/cluster
and organic ligands for better photocatalytic activity of MOFs is the
need for an hour. This review comprehensively reported various MOFs,
their composites, and POM-based MOF materials for the ultimate
photo-degradation of various pollutants in the aqueous phase.
Furthermore, special mention has been given to POM-based MOF material,
which has an advantage over other materials due to their conducting
behavior and high stability. A brief discussion on MOF-based
photocatalysts is explored using various theoretical approaches such as
density functional theory (DFT) and machine learning (ML). Although
there are various article dealing with the basic concept of MOF-based
photocatalyst but the area of combining design structure-activity with
high-performance theoretical analysis have not been discussed in detail
yet. Thus, this article eventually paved the way for applying different
structural features to modulate hazardous materials’ photodegradation
properties toward organic pollutants.

Analysis of thorium and transuranium utilization in a small modular reactor
Authors: Bakir Gizem
Published: February 2023

This study presents neutronic analyses of a small modular reactor utilizing
transuranium and thorium. Two different fuel cases are considered in the
analyses as the transuranium extracted from PWR-MOX spent fuel (a form of a
mixture of minor actinide and Pu isotopes) (Case A) and 4.5 % enriched UO2
with ThO 2(the form of separate fuel rods) (Case B). The total power of
the considered small modular reactor containing 69 assemblies is 450 MW
thermal. In both fuel cases, the time-dependent critical burnup calculations
are carried out by using MCNPX 2.7 code until their effective neutron
multiplication factors decrease to 0.99. The calculations bring out that the
small modular reactor can operate for quite a long time without refueling
and that a new fuel with a richness of 1.05 % can be obtained from ThO as
well 2 as energy production.
A digital twin framework for construction and operation of the radioactive waste repository
Authors: Xu Hong , Duo Yihua , Tang Tao
Published: February 2023

The digital twin is considered the central component of modern industry. It
has been adopted in many industrial fields. However, its application in
nuclear engineering is very rare, especially for the radioactive waste
deposits which is an urgent and tricky issue. Motivated by this demand and
considering China's research & development guidelines for geological
disposal of high-level radioactive waste (a three-step strategy by 2050 to
construct the radioactive waste repository), a framework of the radioactive
waste repository digital twin is proposed. The digital twin uses the
framework + with a multi-layer structure. It can be adopted in the
construction of the radioactive waste repository. It can significantly
strengthen the management capability, reduce the operating cost, improve the
safety level and deal with accidents more efficiently. The first step for
the achievement for the digital twin development of radioactive waste
repository based on the framework is also introduced in the paper. The
proposed digital twin framework of the radioactive waste repository in this
work could be widely used as a reference and easily extended to support
management in other industrial fields.
Etter liberalismen kommer nasjonalismen: 1880-årene viser vei
Authors: Hobson Rolf
Published: February 2023

Sammendrag
Artikkelen reiser spørsmål om hvorvidt den gjengse sammenlikningen av dagens populisme med politiske tendenser i mellomkrigstiden er den mest relevante. En bedre analogi kan finnes mot slutten av 1800-tallet, da liberalismen ble utfordret av demokratiseringen og en forsterket nasjonalisme. Den liberale selvtilliten, siviliseringsmisjonen og den selvbekreftende fremskrittsfortellingen som dominerte i 1860- og 1870-årene, sammenliknes med tilsvarende tendenser i USA etter seieren under den kalde krigen. Etter finanskrakk (i 1873 og 2008), depresjon og lønnsnedslag uttrykte populistiske bevegelser misnøye med liberaliseringens konsekvenser. En utvidet stemmerett muliggjorde en mobilisering som brøt opp eksisterende partistrukturer og utfordret den liberale elitens dominans. Krav om proteksjonisme, innvandringsstopp og statlig inngripen i økonomien fikk gjennomslag under den økonomiske nedgangen som fulgte den store liberaliserings- og globaliseringsbølgen. Bitre sosiale konflikter begunstiget utbredelsen av konspirasjonsteorier. I møtet med denne utfordringen oppga borgerskapet mot slutten av 1800-tallet sin tidligere kosmopolitiske liberalisme og krevde en stadig mer pågående nasjonalistisk opprustnings- og ekspansjonspolitikk. Raseteoriene formet oppfatningen av både innen- og utenrikspolitikk. Dette opinionsskiftet destabiliserte det europeiske statssystemet. Artikkelen spør til slutt om det ikke er denne utviklingen – at det liberale borgerskapet sluttet å være liberalt – som er den viktigste lærdommen vi kan trekke av å sammenlikne vår tid med 1880-årene. 
Abstract in English
After Liberalism Comes Nationalism, as in the 1880s: The article rejects the widespread parallels drawn between the rise of populism in the present day and the rise of authoritarianism and fascism in the interwar years. It seeks instead to find more relevant lessons in the rise of nationalism in the 1880s, when two decades of liberal deregulation and free trade were followed by the “long depression” between 1873 and 1896. Democratization made it possible for an expanded electorate to challenge the dominance of liberal elites. Many groups sought the protection of the nation state from international competition, in tariffs, the regulation of immigration, welfare provision and exclusive access to imperial markets. Conspiracy theories, more particularly modern economic antisemitism, identified the Jews as the “hidden force” behind the instability of globalization, whereas populist movements sought to expel immigrant labour that undercut wages. The most thorough political transformation occurred among the bourgeois elites, which by the end of the century rejected the liberal cosmopolitanism of the 1860s in favour of a neo-mercantilist linkage of military and economic strength, fuelling the colonial and arms races that destabilized international politics.
