Authors: Galvis-Mejia Juan Camilo , Arias-Sarmientopérez Diana Catalina , Castillo-Pastuzán Harold Sebastián , Alvarez-Castillo Leidy Viviana
Published: March 2023

La sepsis en gestantes es una de las principales causas de morbilidad y mortalidad materna, cuyo diagnóstico se retrasa debido a las adaptaciones fisiológicas del embarazo, y a la falta de criterios claros validados en este grupo poblacional. Los gérmenes Gram negativos principalmente Escherichia coli, son su principal causa; sin embargo los Gram positivos, también forman parte etiológica de esta patología. En este reporte, se presenta el caso de una gestante de 36 años de edad, quien desarrolla choque séptico con aislamiento en hemocultivos de Staphylococcus xylosus, y en quien pese a un manejo antibiótico guiado, desarrolla disfunción orgánica múltiple y desenlace fatal. El reconocimiento temprano de la sepsis materna, así como la presunción etiológica y tratamiento dirigido, puede prevenir morbilidad y mortalidad en las pacientes gestantes.
The Fate of Harbin Repatriate in the Mirror of Anthropology: Liudmila Abramova (1914-2002)
Authors: Krotova Mariia V. , Petin Dmitrii I.
Published: March 2023

The research is devoted to repatriate Lyudmila Maksimilianovna Abramova (1914-2002) who was born in Harbin, lived in China for 40 years and moved to the USSR during the mass repatriation of the Russian population of Manchuria in the 1950s. Through the fate of Liudmila Abramova the authors attempt to reflect the peculiarities of the life of the emigrants in Northern Manchuria in the interwar period. They include the involvement of young people in fascist organizations, work in the Manchukuo authorities, survival strategies, repatriation motives, adaptation practices of repatriates, gender aspects - such as the role of a politician's wife, the participation of women in public organizations. The appeal to the personalized history is due to the fact that in the history of Russian emigration in Manchuria there are many mythologemes that distort the idea of the life and activities of emigrants. In addition, the authors had to face the problem of reconstructing the biography of a “little” person in the absence of ego documents (memoirs, letters, diaries); therefore, the research task was the use of the anthropological approach, microand macroanalysis, historical-biographical and historical-comparative methods. The article is based on unpublished archival documents involving memoirs and diaries of former Harbin residents and oral history materials.
Curzon's Ultimatum and Its Impact on the USSR Policy Towards Poland
Authors: Sklyarov Sergey A.
Published: March 2023

The author raises the issue that was practically unexplored on the impact of the British ultimatum delivered to the USSR in May 1923 on the relations between Moscow and Warsaw. The author cites new documents from the diplomatic correspondence of the People's Commissariat for Foreign Affairs' central office (NKID) with the Polish embassy which show that the uproar caused by the Curzon memorandum in the Soviet leadership extended far beyond the sphere of Soviet-British relations. There are analyzed the concessions that Moscow was ready to make in order to prevent Poland from joining the new anti-Soviet front. The comparative-historical analysis is used to examine the dynamics of changes in the nature and scale of these concessions depending on the tension in Soviet-British relations. The conclusion is made that the Curzon memorandum provoked a turn in the Soviet policy towards Poland which Moscow did not fully abandon even when the fears of forming a new anti-Soviet coalition were dispelled. The article also substantiates the reasons why the Soviet leadership decided not to give up its readiness to make a number of concessions to Poland, despite the fact that in June 1923 there was no threat of a new anti-Soviet intervention and Warsaw's participation in it.

Behind the Scenes of the Jam Expedition: Russia's Planning of Warfare in Central Asia in 1878
Authors: Alpeev Oleg Evgen'evich
Published: March 2023

The author examines Russia’s planning of warfare in Central Asia in 1878 while preparing for a possible war with the coalition of Great Britain, Austria-Hungary and Turkey. The development of the war plan was caused by the inability of the Russian army weakened by the Russo-Turkish War of 1877-1878 to conduct active military operations in Europe. Instead, it was aimed to influence Great Britain by creating a threat to its richest colony - India. In the historical literature there is no clear answer to the question about the goals of the unsuccessful Jam expedition. In this regard, the aim of this research is to reveal the content of the failed campaign’s plan based on the available historical sources and try to reconstruct Russia’s war plan against Great Britain in Central Asia, as well as to show its significance in the further process of war planning in the region. The author comes to conclusion that the Russian military-political leadership initially expected to invade India, but due to the changed situation they conducted just demonstration actions. The failure of the Jam expedition showed the Russian commanders the need to search for a springboard for future actions against India. Moreover, based on the experience of the unsuccessful campaign, the Russian commanders began regular planning for war against Great Britain in Central Asia which provided for the conduct of offensive operations in the direction of Herat.
Orthodoxy in Western China and Central Asia: Historical Background
Authors: Smirnova Irina Yu.
Published: March 2023

The author discusses the prehistory of the spread of Orthodoxy among the residents of Western China that was inextricably linked to the policy of Russia in Central Asia in the second half of the 19th century and traces the first missionary projects carried out in Ghulja (1851) among the descendants of captive Albazinians exiled from Beijing to the Chinese Ghulja in 1712. While reconstructing the history of Orthodoxy in the Ile region, it was revealed that the initiative of Orthodox missionary work in Western China originally belonged to eminent churchman Parfeny (Aggeev); it was supported by Metropolitan Philaret (Drozdov) of Moscow and brought to the attention of Emperor Nicholas I. The study of the official diplomatic correspondence in the period of the 1850-60s showed that the attitude of Russian diplomats to the missionary work of the Russian Orthodox Church in China was negative as this activity might exacerbate foreign policy relations between Russia and China. At the same time, the establishment of Orthodox churches at the Russian consulates in Ghulja and Chuguchak played a crucial role in the spread of Orthodoxy in Central Asia and Western China.
Russian Architectural Heritage in the Xinjiang-Uygur Autonomous Region of China as Manifestation of Interethnic and Intercultural Interaction in the 19th-21st Centuries
Authors: Nazemtseva Elena N.
Published: March 2023

The author identifies the Russian architectural heritage in the Xinjiang Uygur Autonomous Region of China in the process of intercultural and interethnic interaction of the Russian Diaspora with the peoples of the province. In this regard, the subject of the study is the preserved monuments of Russian culture - residential buildings, temples, cemeteries. The structure of the study is determined by the need to explore the mutual influence of the culture of the Russian diaspora and those of local peoples on the example of architectural structures. The research is based on modern literature, as well as documents of Russian archives: materials deposited in the Archive of Foreign Policy of the Russian Empire, the Archive of Foreign Policy of the Russian Federation, the State Archive of the Russian Federation, the Russian State Military Historical Archive. Most of them have not been introduced into scientific use before. The author identifies the features of intercultural and interethnic interaction of representatives of the Russian diaspora with local peoples for a long time and depending on the political situation in the region. It is noted that at the stage of the formation of the Russian Diaspora in the XUAR there were difficulties in the relations between Russians and representatives of local ethnic groups. At the same time, the local culture had a serious impact on the development of the Russian diaspora. There is noted the rather competent policy of the Chinese and Russian authorities at the present stage to support the culture of Russians in Xinjiang, although the author does not exclude difficulties in its further preservation. Therefore, according to the author, there is a need for further close interaction between the Chinese and Russian authorities in order to determine new courses of cooperation in this direction.
Diplomat and Reformer S.L. Vladislavich-Raguzinsky: “...Eternal Peace Was Concluded and the Border Was Approved”
Authors: Zandanova Larisa Viktorovna , Puzynya Nikolay Nikolaevich
Published: March 2023

The authors consider the period of stay of Count Sava Lukich Vladislavich-Raguzinsky, from 1725 until 1728, in Eastern Siberia during and after his diplomatic mission to the Qing Empire. His role in the expansion and strengthening of Russia’s influence on the eastern borders is established. Particular attention is paid to the issue of streamlining relations between the local administration and the indigenous population, the restoration of bilateral trade between Russia and China, the arrangement of the border and trade territories, the organization of missionary activities of the Orthodox clergy in Siberia and the Qing Empire. All this significantly influenced the development of the peoples and territories of the region during the process of Russia’s expansion in the east, the change of its role in Russia's foreign policy in the Far East. Nowadays, especially relevant is the provision written by the ally of Peter the Great in the Treaty of Kyakhta that between Russia and China “peace should be sustainable and eternal” and the interstate border should become peaceful at all times.

PENERAPAN MEDIA AUDIO VISUAL UNTUK MENGENALKAN NILAI AKHLAK PADA ANAK DI TK AL-HIDAYAH ACEH SELATAN
Authors: Ismail Muthmainnah , Fajriah Heliati , Humaira Firiza
Published: March 2023

The introduction of moral values is a form of human development to become a human figure who is devoted to Allah SWT. Moral development must start early to form good character in children. Based on the observations of children in TK Al-Hidayah, children have not been able to distinguish between good values because of the limited use of media at that school. At that level, children should be familiar with honesty, politeness, respect, caring, and helping each other. This study aims to introduce moral values by using audio-visual media. This experimental research used a one group pretest-posttest design on 15 children of Al-Hidayah Kindergarten. Data collection uses a test to see the child's ability to recognize moral values through the animated films Nusa and Rara. The results showed that children began to recognize moral values before using audio-visual media with an average of 1.6. But after seeing the animation, the average value is 3.2 (Already Familiar). Then the t test obtained a t_count value of 23.98 and a t_table value of 1.761 with 14 degrees of freedom (db) at a significant level of 5% (0.05) and the difference in pretest and posttest values was 1.6. Based on data analysis, it can be said that t_count > t_table so that Ha is accepted and Ho is rejected. So it can be concluded that the application of audio-visual media can introduce children's moral values in Al-Hidayah Kindergarten, Samadua District, South Aceh Regency.
Cost of crime in Russia: A compensating variation approach

Published: March 2023

The paper estimates the cost of crime in Russia through an indirect approach. Using a national victimization survey, we estimate the elasticity of life satisfaction with respect to victimization and income. With estimated elasticities, we calculate the compensating variation: the increase in household income which would compensate for the decrease in life satisfaction due to victimization. Assuming strict exogeneity, one crime costs 135.2 thousand rubles ($2190), and the total societal cost amounts to 1.75 trillion rubles ($28.3 billion) of annual household income (1.3% of GDP).
In the Search of Secret Meaning: the Role of “Inner Commentary” in Nasir-i Khusraw’s Poetic Works (11th Century)
Authors:   Lomonosov Moscow State University, Reysner Marina L.
Published: March 2023

The research is devoted to the function of inner commentary in the Nasir-i Khusraw’s poetic works. Being the outstanding religious philosopher and Ismaili Teacher, he had reformed the artistic language of Persian Classic Poetry with the help of strategy of allegorical commentary ta’wil, which was firstly used only on the Quran’s text. He used the traditional form of qasida for didactic aim. Сonventional poetic motifs and standard beginnings served as the basis for creating allegories of varying degrees of complexity. The objects of this article are some examples of allegories based on traditional poetic motifs and standard beginnings of Nasir-i Khusraw’s qasida, his interpretations of term ta’wil and author’s discourse upon form and meaning of Word. The article also deals with different kinds of inner commentary in Nasir-i Khusraw’s three spring qasida. The analysis shows that on the first stage of formation of mystic poetry’s language commentary, giving secret meaning of text was the sphere of author’s individual initiative. At the stage of fixing the created connotations in the canon, they become stable and to a lesser extent depended on the presence of the author’s commentary, thus the allegorical ambiguity of the text becomes the generally accepted norm.
Specific Features of Forming French-Language Literatures of Sub-Saharan Africa as the Regional Typological Commonness
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Lyakhovskaya Nina D.
Published: March 2023

The article is dedicated to basic methodological principles of studying Frenchlanguage literatures in Western and Central Africa. In 60s–70s of the 20th century, foreign Africanists-literature scholars, such as Jacques Chevrièr, and domestic ones, I.D. Nikiforova in particular, studied such literatures as a typological commonness with basic peculiar features or characteristics. The first one is the French language with the tendency for the indigenisation and creation of a “hybrid message.” The second one is the general idea-driven and artistic paradigm: the anticolonial orientation, traditional Africa presentation, protection of the authentic culture, folklore, spiritual values. As distinct from foreign Africanists, both Nikiforova and other Russian scientists emphasised the national specific character of regional literatures, having substantiated two more features that are essential: the accelerated development and parallelism or “compression of styles,” alignment of various art movements within a single temporal space. By the late 20th century, the vector of African studies moved towards the analysis of certain literatures in such typological commonness, thus enabling to determine their national distinctness to a deeper and more precise extent.
Culture Codes in Children’s Literature: Voices from Scotland and Armenia
Authors:   Kostroma State University, Zimina Evgeniia V. , Sargsyan Mariana S. ,   Yerevan State University
Published: March 2023

The article studies culture codes in contemporary children’s literature and aims to identify how language units and imagery condense and transmit the culture code of a specific society and epoch. The authors narrow down the research to two countries — Scotland and Armenia — because of the common features of their children’s literature: the use of a different language in fiction, the approach to the cultural component in fiction and the influence of the countries’ past. The research has two distinct directions: based on selected texts by Scottish writers the paper discusses the issue of transmitting culture codes in a multi-voiced medium. Further, based on the text by Narine Abgarian, a Russian writer of Armenian origin, the culture codes of childhood in the multicultural setting are discussed. It is argued that despite the current trends in the international book market, children’s literature containing authentic cultural information should be promoted. Such children’s literature performs an important mission toward shaping the readers’ identity, raising awareness of one’s own culture and facilitating intercultural communication.
Creative Search by Richard Strauss and Hugo von Hofmannsthal in the Opera “Ariadne on Naxos”: to the Problem of Music and Words Interaction
Authors:   National Research Lobachevsky State University of Nizhny Novgorod, Sharypina Tatiana A. , Kazakova Polina D. ,   National Research Lobachevsky State University of Nizhny Novgorod
Published: March 2023

The subject of the article is the problem of the synthesis of arts in the creative collaboration of Hugo von Hofmannsthal and Richard Strauss. А special turn of the problem «music and word» is analyzed, when a musical performance arises in close cooperation between a composer, who is responsible for correcting the text and a writer dealing with the musical palette of their common creation. R. Strauss and G. Hofmannsthal were united by the very concept of the philosophical and aesthetic inheritance of F. Nietzsche, whose research predetermined the theoretical and philosophical basis of their cooperation. The creation of the play «Ariadne on Naxos» was based on the principles, in many respects similar to the Nietzsche's concept of the relationship between music and word. It also made it possible to turn to mythological operas «Helena of Egypt». It is concluded, the work on the opera «Ariadne on Naxos» has become a long-awaited synthesis of opposing views on antiquity and the deep origins of ancient Greek art for its creators.
On the “double leverage” of US insurance groups
Authors: Bressan Silvia
Published: March 2023

We show that a high degree of “double leverage” inside US insurance groups affects in a negative way their financial strength. Double leverage occurs when the parent firm finances the purchase of subsidiaries’ equity using external debt proceeds, i.e., without changing its stand-alone capital. The previous evidence shows that the double leverage of US Bank Holding Companies leads the firms to become riskier (Bressan, 2018b) and less efficient (Bressan et al., 2021). While regulators give instructions for the assessment of double leverage inside banking groups, in the insurance sector this topic has not received enough attention from either regulators or scholars. This article aims to fill this lack of knowledge by using data from the balance sheets of US insurance groups during the years 2000–2021, showing that indicators for the solvency and the performance of insurers decrease significantly in measures of double leverage. These findings deliver important implications for future policymaking. As we analyze accounting data from consolidated balance sheets, we argue that regulators should more carefully consider whether consolidation rules are sufficiently informative about the financial stability of insurance groups. This is an important task in relation to the systemic relevance of insurance corporations. Finally, this article is a starting point for follow-up research testing, for example, the link of double leverage to captive insurance (Weterings, 2014) and reinsurance (Park & Xie, 2014; Bressan, 2018a).

Published: March 2023

This study constitutes a novel concept that provides a complete analysis of the holding business at an Islamic-based school (Pesantren) and the halal value chain. The halal value chain provides a standard for sharia-compliant production, distribution, or consumption activities. This case study was based in Pesantren Al-Rifa’ie, addressed in Malang East Java Indonesia. This study collected data through interviews, contract data, SOP, financial statements, BMT reports, and observation. The data were analyzed using the heuristic case study. The results showed that the holding business at Pesantren Al-Rifa'ie was in the form of a cooperative since it combines business units. The cooperative has funding, financing, and BMT activities. BMT is profit-oriented through establishing business units. Business units supporting the halal value chain were husbandry, bus rentals, and One Pesantren One Product (OPOP) starting from the input, process, and output. This research strengthens the New Institutional Theory and provides insight into the need for technical requirements to establish the company holding in Pesantren.

HBV remains a public health concern. Blood donors screened for HBsAg
along with AST/ALT could play a key in providing safe blood products. We
investigated the features related to HBV infection among rejected blood
donors in Luanda, Angola. This was a cross-sectional study conducted
with 164 rejected donors. Donors were screened for HBsAg from March to
May 2022. Overall, 63.4% tested positive for HBV. Mean age of the
HBV-positive (29.2±8.02) was lower than the HBV-negative (33.9±10.0)
(p<0.001). Donors between 20–40 years (OR:2.34, p=0.045),
females (OR:1.40, p=0.516), residents in urbanized areas (OR:1.23,
p=0.530), low educational (OR:1.54, p=0.458), unemployed (OR:1.65,
p=0.271), and unmarried (OR:1.41, p=0.616), might be likely to contract
HBV. AST/ALT ratio was higher in HBV-infected (2.07±1.42) than in
HBV-uninfected (1.90±1.14). About 20% of HBV-positive were classified
as having acute liver disease, while 80% with chronic liver disease,
based on AST/ALT ratio. Age ranged from 20-40 years (OR:1.97, p=0.305),
females (OR:1.61, p=0.557), donors from non-urbanized (OR:1.69,
p=0.557), a low educational (OR:1.64, p=0.571), and unemployed donors
(OR:1.81, p=0.289) were likely to develop chronic liver disease. Our
findings indicated the failure of viral hepatitis control measures.
Authorities should consider including HBV nucleic acid testing to ensure
early identification of HBV in Angola.

Purpose Successful utilization of anatomical templates in the
evaluation of diffusion-weighted neuroimaging-studies requires accurate
registration of intra-individual datasets. We investigated the
feasibility of structural MRI image registration onto single-shot and
read-out segmented echo-planar diffusion-weighted imaging variants for
use in tractographic samplings of the visual system, in particular the
optic nerve. Methods Slab volumes of the optic nerve pathway
from thirteen volunteers were acquired and preprocessed. Three
neuroradiologists marked landmarks (ROIs, regions of interest) on two
diffusion-weighted and one structural dataset. Structural ROIs were
respectively registered (6/12 degrees of freedom, DOF) onto single-shot
(ss-EPI) and readout-segmented (rs-EPI) volumes. All six ROI/FOD (fibre
orientation distribution) combinations underwent a targeted tractography
task (MRtrix3: iFOD2). Results Inter-rater reliability for
ROI-placement was highest in VIBE images (0.66 to 0.95, mean 0.85) and
lower in both ss-EPI (mean 0.77) and rs-EPI (0.46 to 0.84, mean 0.64).
Sufficient FOD generation in the optic nerve was successful in 12/26 of
all cases for ss-EPI volumes (46.2% of cases) and in 18/26 for rs-EPI
volumes (69.2%). Spatial shift of VIBE-drawn ROI-coordinates after
6-DOF registration was highest for ss-EPI-targets (medians: 1.15 to 1.4
mm; rs-EPI 0.82 to 0.93 mm), whereas 12-DOF registration caused less
spatial shifts (ss-EPI: 0.64 to 1.03 mm; rs-EPI: 0.58 mm to 0.79 mm).
Tractography results revealed no significant differences between ss-EPI
and rs-EPI sequences on cases with mutual generation of sufficient FODs
(n=10). Conclusion Structurally-placed ROIs (highest
inter-rater reliability) with 6-DOF registration onto rs-EPI targets
(highest FOD-generation rate) seems most suitable for white matter
template generation.

Published: March 2023

The current study makes an attempt to emphasize that the criminal policy in Russia on liability for tax-related offenses holds a steady tendency toward humanizing. To meet that aim, the present study utilizes the dialectical approach of cognition of legal and social concepts and phenomena in their interdependence as well as development. Based on the results obtained, tax evasion is comprised of acts, such as deliberately including false information in the tax return or other documents, the submission of which is mandatory according to the legislation on taxes and fees in Russia, or simply failing to submit any of these documents.
Application of pyrophyllite in high-temperature treated building materials
Authors: Terzic Anja , Vasic Milica , Stojanovic Jovica , Pavlovic Vladimir , Radojevic Zagorka
Published: March 2023

Phyllosilicate mineral pyrophyllite is predominantly used in the ceramic industry because it exhibits high refractoriness. Due to its thermal transformation into mullite, pyrophyllite is stable at elevated temperatures, making it a suitable mineral additive for refractory non-shaped materials and various ceramic shaped products. In this study, pyrophyllite is employed as 50 % clay replacement in the ceramics and up to 30 % cement replacement in mortars. Physico-mechanical properties were investigated. The firing shrinkage in the ceramics treated at 1200 ?C was reduced by pyrophyllite addition. Pyrophyllite acted as additional pozzolana during cement hydration. Within the microstructure, it formed micro-reinforcement in the shape of crystalline folia, which improves the mechanical properties of ordinary Portland cement, high aluminate cement, and blended cement mortars. The investigation proved the efficiency and suitability of pyrophyllite employed as a substitution for clay in ceramics and a cement replacement in mortars.

Single nano high-entropy pyrochlore-type compound (A2B2O7) with 7 different rareearth cations at site A and 3 different metal cations at site B with equiatomic amounts (7A1/7)2(3B1/3)2O7 is successfully obtained. The powder with nominal composition (La1/7Sm1/7Nd1/7Pr1/7Y1/7Gd1/7Yb1/7)2(Sn1/3Hf1/3Zr1/3)2O7 was fabricated by reacting metal nitrates (site A) and metal chlorides (site B) with glycine during the combustion reaction. The XRD analysis revealed that the powder attained during synthesis is in an amorphous state. To induce crystallization of the obtained pyrochlore structure, the post-calcination process at 600-1500?C was conducted and studied. Results of this study showed that the monophase pyrochlore (A2B2O7) structure is obtained during the calcination at 900?C. The high-density ceramic pellet with 97% of theoretical density and free of any additives was obtained through pressureless sintering at 1650?C for 4 h in the air using the powder calcined at 900?C.
Modelling of mixed thermodynamic model based on new materials
Authors: Geng Cheng
Published: March 2023

In order to solve the problem of the performance of mixed alkane phase change
energy storage materials, this paper proposes the modelling research of
mixed thermodynamic model based on new materials. In this paper, the
thermodynamic performance of binary mixed alkane system is studied, the
influence of phase transition temperature, phase transition enthalpy and its
composition on the mixed alkane system is explored, and its solid-liquid
phase diagram is drawn. We used different thermodynamic models to predict
the phase transition temperature and enthalpy in the melting process of
binary mixed alkanes, which were mutually verified with the experimental
results. The experimental results show that C9-C10 and C9-C11 systems
exhibit eutectic behavior. The eutectic components are 88% (mass fraction,
the rest is the same) C9-12% C10 and 90% C9-10% C11. The eutectic
temperatures are 218.25 K and 215.15 K, respectively. The C8-C9 system has
peritectic phenomenon, C10-C11 system shows complete mutual solubility, and
their mini?mum melting points are 200.25 K and 234.35 K, respectively.
Conclusion is that the C9-C10 and C9-C11 eutectic systems are suitable for
low temperature phase change materials in the temperature range of 210-220
K, providing data reference for their application in low temperature energy
storage.
The bearing capacity parameter analysis and heat energy storage loss test of concrete composite box girder
Authors: Gong Baojia
Published: March 2023

In order to study the relationship between the bearing capacity of the
structure and the damage degree, the author proposed the bearing capacity
parameter analysis and the heat storage loss test of the concrete composite
box girder. Taking the five-span prestressed concrete composite box girder
as an example, different degrees of damage are simulated by reducing the
bending stiffness of different parts, and the modal strain energy method and
flexibility difference method are used to diagnose the structural damage.
The test results show that for the first span, the sum of the structure can
meet the corresponding specification requirements under the condi?tion of
dense traffic and less than 20% damage. When the damage is greater than 20%,
the first span beam cannot meet the driving requirements. Under general
traffic conditions, when the damage is less than 30%, the structure can
basically meet the driving requirements, and the second and third spans
still have a high safety factor. In the case of 30% damage of the first
span, although ? it does not meet the requirements, but RF > 0.9. Each
monitoring point has good estimation accuracy, and the error between the
maximum temperature occurrence time of each monitoring point and the maximum
temperature occurrence time of the mon?itoring point is within ? 10 hours .
For continuous composite box girder structure, the flexibility difference
method is superior to the modal strain energy method.

of heat energy in the traditional oil cooler of Marine hydraulic system, the
waste heat recovery and reuse of Marine hydraulic oil temperature control
system is proposed. The hydraulic system waste heat recovery test platform
has been established, the influence of electrical load, oil flow rate and
working medium flow rate on system operation and energy characteristics is
studied. The experimental results show that under the same working
condition, compared with the oil cooler of the same specification, the
maximum thermal efficiency of the proposed organic Rankine cycle waste heat
recovery system is increased to 2.56%. The expander pressure ratio and
system thermal efficiency increase with the increase of electric load and
oil flow. The experimental results analyzed the energy saving effect of
waste heat recovery system on hydraulic system, and obtained the rule of
system operation efficiency.

In order to solve the shortcomings of single air source heat pump, single
solar heat pump and solar air double heat source heat pump, one solar
electric heat pump and multi-stage solar heat pump dual source heat pump, a
solar integrated heat source heat pump is designed. The heating capacity and
COP of the same heat pump and the solar double heat pump under three
different operating conditions were simulated, and the simulation results
were compared and analyzed. The simulation results were analyzed. The
results show that the heat capacity and COP of the solar double heat pump
system are higher than those of the heat pump system. With the continuous
decrease of outdoor temperature, the advantages of solar wind tunnel hybrid
heat pump system are more obvious.

Authors: Giruzzi Nicholas R. , Yepez Catalina , McKeirnan Kimberly
Published: March 2023

This article describes a pharmacist-led diabetes care program implemented at a local free clinic for underserved Hispanic patients with low or no income. Patients are referred to the pharmacist after diagnosis with diabetes for a consultation that includes disease state education, diet/lifestyle education, medication management, and follow-up. The pharmacist works with patients to ensure timely follow-up and adequate medication adjustments to achieve goals. In its first 16 months, this service led to a statistically significant decrease in A1C for Hispanic patients, with an average 2 percentage point reduction in A1C.
The Status of Snow Leopards (Panthera uncia) Conservation in Jigme Khesar Strict Nature Reserve at Haa, Bhutan
Authors: Wangyal Jigme Tshelthrim
Published: March 2023

Study of Snow Leopard (Panthera uncia, Schreber, 1775) using infrared camera traps along actively used tracks, scent-sprayed rocks, scats and scrape sites was conducted in the mountains of Jigme Khesar Strict Nature Reserve, Haa, Bhutan between October and December 2015 and it is still being continued. A total of 17 grids, each measuring 16km2 were sampled covering a total area of 272 km2 . Thirty-four camera traps were stationed in 17 grids and in a total of 60 trap nights, 215 images of Snow Leopard were captured out of which 163 images were considered for analysis. Using the pelage patterns on the body parts such as forelimbs, face, flanks and dorsum of the tail of the captured individuals, a total of ten different individuals were identified including the one that was recorded during the extended period trapping for a month. Capture history of camera trap station G9 (Kampula) indicated that it had the highest concentration of the species as individuals JKSNR 3, 4, 8 and 9 were all captured at the same station. The capture timing of the species confirms its crepuscular nature as most of them were recorded between dawn and the dusk. Our results suggest that the species can be well monitored and conserved using camera traps. The Reserve can focus on patrolling and monitoring of the species in the identified high-density areas for maintaining the moving population to perpetuity.

Escrito em três línguas – embora suas partes não sejam traduzidas em todas as línguas que o constituem – esse texto tripartido tem dois objetivos: primeiramente, busca fornecer uma ideia geral do curso - três cursos em um - que foi oferecido durante a primavera europeia e o outono brasileiro de 2021 por três professoras em parceria para os seus alunos de mestrado e doutorado, ou seja, para estudantes, em sua maioria, das três universidades onde elas lecionam, promovendo uma discussão densa e uma visão ampla acerca do tema do curso, qual seja, Metodologias Críticas de cunho colaborativo, especialmente as que se embasam nos estudos histórico-culturais, conforme discutidos por L. S. Vigotski (1924-1934). O curso foi organizado a partir da ideia inicial e central de uma oportunidade para aprofundar a compreensão dos aspectos que aproximam e diferenciam os trabalhos das três pesquisadoras - Clínica de Atividades, Pesquisa-Trans-Formação, Pesquisa Crítica de Colaboração - e de seus grupos de pesquisa, especialmente no tocante às metodologias empregadas e ao seu trabalho com profissionais da educação. Os resultados das discussões demonstram que as três metodologias se apoiam, em maior ou menor escala, em conceitos tais como contradição, trabalho colaborativo, instrumento-e-resultado, dialética, totalidade-unidade, sentido e significado (ou significação), entre outros. Alguns autores foram também convidados para contribuir com sua visão sobre aspectos específicos da teoria histórico-cultural e/ou possibilidades metodológicas que podem ser desenvolvidas a partir desses estudos. Já outros autores que contribuíram com esse número temático da Revista Psicologia da Educação foram participantes do curso em si – como professores convidados ou como estudantes – e apresentam suas visões sobre o que foi discutido nas semanas de trabalho, i.e., as metodologias de pesquisa e suas bases ou as ideias principais que surgiram nas discussões e contribuíram com a elaboração dos componentes metodológicos de suas teses ou dissertações.
ensino da língua brasileira de sinais (Libras) sob a ótica de um professor surdo e de uma professora ouvinte
Authors: Hollosi Marcio , Vieira Claudia Regina
Published: March 2023

A Libras é reconhecida como língua da Comunidade Surda brasileira desde abril do ano de 2002, esse reconhecimento se deu graças a uma intensa mobilização da Comunidade Surda. Embora algumas pessoas afirmem que ela é a segunda língua oficial do Brasil, na verdade é uma língua reconhecida como “língua das comunidades surdas brasileiras (Brasil, 2002)” e esse reconhecimento se deu a partir da Lei 10436/02. Após o reconhecimento da língua o Decreto 5626/05 trouxe a obrigatoriedade do seu ensino para os cursos de licenciaturas. Podemos dizer que esse primeiro contato dos licenciandos com a realidade da trajetória dos surdos por educação e da complexidade da Libras é extremamente importante para que os processos de desenvolvimento da Comunidade sejam garantidos e principalmente para que a Língua de Sinais não seja banalizada, simplificada ou fique subordinada à Língua Portuguesa. Neste trabalho, trazemos um pouco da experiência como professores da disciplina em universidades federais, um surdo e uma ouvinte. Além disso, trazemos alguns dados produzidos em um projeto de formação com professores surdos de uma instituição escolar bilíngue para surdos. A partir dos discursos trazidos por esses atores, analisamos os dados com base nos princípios da PCCol - Pesquisa Crítica de Colaboração, Magalhães (2006), que destaca como uma perspectiva teórico-metodológica que favorece a co(construção) dos participantes da pesquisa, assim como a uma construção coletiva de escola e Universidade. Trata-se de um quadro que revela nosso compromisso como professor/a-pesquisador/a, que perseguem a ideia de que ensinar e aprender compõem um caminho de mão dupla.
Spectral and wavelet analysis in the wake of an airfoil with Gurney flap
Authors: Giacopinelli P. , Scarabino A. , Bacchi F. , Delnero J.
Published: March 2023

In this work we identify the coherent vortices in the leeward wake of an HQ 17 airfoil with a Gurney flap. This high-lift device consists of a small plate perpendicular to the airfoil, at or near the trailing edge, with a height � of the order from 1% to 4% of the chord. The overall effect is to produce a significant increase in lift, together with a relatively minor increase in airfoil drag. Its geometry generates vortex shedding of spatial scale H, which modulates the wake and thus influence the global configuration of the flow. A numerical study was performed with the commercial software ANSYS Fluent. Simultaneously, experiments were carried out in the wind tunnel of the Aeronautical Departmental Area from the Engineering School of the National University of La Plata. With a Dantec StreamLine hot-wire anemometer, records of the instantaneous horizontal and vertical velocity components in the airfoil wake were obtained. Both the experimental data and those obtained by numerical simulation were analyzed with the continuous wavelet transform technique, in order to identify and characterize the coherent vortices in the wake. Results show the shed vortices structure and the organization degree of this periodic shedding.
Buğday saplarından KOH yöntemiyle elde edilen kağıt hamurlarının parlaklık ve opaklık değerlerinin incelenmesi ve modellenmesi
Authors: GENÇER Ayhan , KURT Rıfat
Published: March 2023

Bu çalışmada, buğday saplarından KOH yöntemiyle kâğıt hamuru elde edilmiş ve deneme kâğıtlarının L*, a* ve b* değerleri, opaklık ve parlaklık değerleri ölçülerek sıcaklık artışı ile meydana gelen değişim incelenmiştir. Bu kapsamda pişirme süresi ve KOH oranı sabit tutularak, maksimum sıcaklık değerleri 110, 120 ve 130 ℃’lerde değiştirilmiş ve üç farklı hamur elde edilmiştir. Her üç pişirmede elde edilen hamurlardan elde edilen kâğıt gruplarında L* değeri 70’in üzerinde ölçülmüştür. Bu kâğıtların beyaza yakın olduğu anlamına gelmektedir. a*,b* değerleri + değerde olduğundan kâğıtlar kırmızı ve sarı renktedir. b* değerinin a* değerinden oldukça yüksek olması sarı rengin kırmızı renge göre daha baskın olduğunu göstermektedir. Dövme ile opaklık azalmıştır. Hamurların parlaklık değerleri aynı °SR indisinde 110 ℃’den 120 ℃ çıkarılması ile azalmış 130 ℃’ye çıkması ile tekrar artmıştır. Bununla birlikte çalışmada, opaklık ve parlaklık değerleri regresyon analizi ile modellenerek farklı °SR indisi ve sıcaklık değerlerindeki kâğıt hamuru parametreleri tahmin edilmiştir.
Higher-Order Effects in Biaxial Flexure of GFRP I-Section Beams
Authors: Razzaq Zia , Razzaq Faridoon Z.
Published: March 2023

A theoretical study of Glass Fiber Reinforced Polymer (GFRP) beams subjected to biaxial bending moments is presented with a focus on the influence of higher-order effects on maximum normal stresses. It is shown that the biaxial bending type of loading causes a dramatic increase in the maximum normal stress for a GFRP beam when induced torsional effects are included. The study demonstrates that the traditional first-order theory can grossly underestimate the maximum normal stress in a GFRP beam. Based on the numerical results presented using a higher-order theory which also accounts for induced warping normal stresses, the maximum normal stress is found to be about two to three times larger than that determined using the first-order theory.
Ein Rahmenmodell für den kunstbasierten Fremd- sprachenunterricht – unter Einbezug von Theater, Bildender Kunst, Musik und Literatur
Authors: Wirag Andreas
Published: March 2023

This article presents a framework model for a foreign-language classroom that makes use of the Arts (i.e., drama, visual arts, music, literature, etc.). This model contains the central elements of an Arts-based foreign-language instruction, which are arranged to form a plausible causal structure of the classroom teaching and student learning. As intermediate teaching outcomes, the model assumes changes in students’ personality states, i.e., changes in their current motivation, creativity, or empathy, which result from the students’ engagement with the Arts. As final teaching outcomes, the model assumes a development of students’ L2 competences, i.e., of their L2 speaking, listening, writing, reading, mediation, vocabulary, and grammar skills. The framework model is based on earlier accounts which assume that all teaching outcomes derive from an Arts-based foreign-language instruction as final teaching results. In contrast, the present framework assumes that Arts-based teaching outcomes are partially nested.

Authors: Altowairiki Noha Fahad
Published: March 2023

This qualitative case study explored the development of online teaching capacity to incorporate the universal design for learning (UDL) framework in an online graduate program. The participants in the study were purposefully selected from multiple levels at a Canadian university: (1) the program level, (2) the faculty level, and (3) the institution level. Using a series of semi-structured interviews and document analysis, four themes were identified: (1) leadership, (2) community of practice, (3) educational development, and (4) challenges. In addition to highlighting the roles of academic leaders in fostering UDL adoption in online learning, the findings also revealed forms of support that need to be in place to increase online teaching capacity. The findings from the study provide valuable input toward setting the stage for UDL to be meaningfully adopted in an online learning setting.
