Authors: Arifian Naf’an , Denis Kemal Rahman , Putri Sri Kandi
Published: March 2023

This study uses two DEM images, namely ASTER GDEM and DEM SRTM to map the distribution of rivers and geomorphology located in The District of Pesisir Selatan. In this study a comparison of the two images was carried out with the same level of resolution of 30 meters to see the accuracy of the images used in the study of watersheds and geomorphology.

The method used in this research is processing image data then identifying the river for each image used. Further carrying out a confusion matrix which is used to check or improve data from a quantitative approach.

The results of the study in terms of comparison of ASTER and SRTM images for watershed identification show that SRTM imagery is more accurate in identifying watersheds compared to ASTER imagery. After taking samples with the number of sample points taken, namely 36 samples on each, and then testing for spatial accuracy, the results show that the SRTM imagery had an accuracy rate of 88% where out of 36 sample points only 5 were wrong or not on the river. Whereas in the ASTER image of 36 sample points, there were only 6 which were right on the river, show that the level of image accuracy is only 14% for river identification. The study also shows that after the research process and accuracy test, for geomorphologic identification on the two DEM images, namely DEM SRTM and ASTER GDEM, it found that both images have the same level of accuracy, therefore both images are equally good at identifying geomorphology.

Authors: Widiatmika Putu Wahyu , Bagus Made Ari Segara Ida , Netra I Made
Published: March 2023

This study aims to know the relation of Balinese cultures with the animal and plant lexicons in Balinese songs from the perspective of eco-linguistics. The data from this study were collected from YouTube. Listening and documentation methods along with transcription techniques were applied to collect the data. The animal and plant lexicons found were subsequently analyzed using the method of descriptive-qualitative with the help of Bang and Døør’s theory of dialectical eco-linguistics and the eco-linguistics parameters from Fill and Muhlhausler. The result of this study shows that the animal and plant lexicons used resulted from the co-existence of Balinese people and other species in their environment. The lexicons are inserted into the songs through the concept of metaphor. The co-existence makes Balinese people able to give meanings towards the animal and plant in the song based on their cultures and beliefs.

XIX. Yüzyılın İlk Yarısında Doğu Akdeniz’de İngiliz-Rus Nüfuz Mücadelesinin Merkezi Olarak Kudüs
Authors: YURDAKUL Nurcan
Published: March 2023

XIX. Yüzyılın iki büyük siyasi gücünün Doğu Akdeniz’de karşı karşıya gelişleri öncelikle Kudüs ve çevresinde gerçekleşmiş, İngiltere’nin Hindistan yollarını kontrol altında tutmaya yönelik dış politikası Napolyon tehlikesinin bertaraf edilmesinden sonra Rusya’nın bölgede atacağı adımlara odaklanmıştır. Başka bir ifade ile İngiltere, Rusya karşısında reaktif bir Doğu politikası izlemiştir. Rusya’nın sıcak denizlere inme siyaseti Büyük Petro’dan beri sabit kalmış ancak ideolojik arka planında olan Ortodoksları himaye etme siyaseti Rusya’daki siyasal, sosyal, askeri gelişmelerden etkilenerek gelişmeye devam etmiştir. Filistin ve Suriye’deki Osmanlı tebaası olan Ortodoks Arapları kendi sınırları dışında kalan tebaası olarak gören Rusya’nın, Osmanlı İmparatorluğu karşısındaki zaferleri ertesindeki tüm siyasi antlaşmalarına bu iddiasını derç ettirmesi ve bu tebaa üzerinde nüfuz kurmaya başlaması, İngiltere’nin de bölgede konsolosluk ihdası ve misyonerlik faaliyetleri üzerinden nüfuz kurma siyaseti gütmesine sebep olmuştur. Sonuçta Ortodoks Arapları ve Yahudileri Protestanlığa ihtida ettiremeyen İngiltere Osmanlı tebaası olan Yahudileri himaye etmeye yönelmiş ve Rusya’ya yönelik reaktif Doğu politikası kapsamında Filistin’e Yahudi göçünü teşvik etmeye başlamıştır.
El neoliberalismo argentino y sus antagonistas políticos. El caso de Álvaro Alsogaray
Authors: Méndez Pablo Martín
Published: March 2023

El siguiente artículo se propone indagar el proceso de formación del neoliberalismo argentino tras la caída del primer peronismo. Para esto recurre a las herramientas metodológicas brindadas por la arqueología de Foucault y la teoría del discurso de Laclau. El material de análisis son los principales escritos publicados por Álvaro Alsogaray, uno de los máximos referentes del neoliberalismo argentino. Según el argumento desarrollado, el neoliberalismo de Alsogaray se constituyó a partir de: 1) la articulación con las ideas neoliberales que circulaban en Europa a mediados del siglo XX; 2) la definición de un nuevo antagonista político conformado por la relación equivalencial entre el peronismo, el desarrollismo, el radicalismo, la social-democracia y el totalitarismo económico; y 3) la configuración de un programa político destinado a sentar las bases de una “Economía Social de Mercado”. El artículo señala finalmente cómo el antagonismo contribuyó a definir la identidad política del neoliberalismo argentino.
La resistencia de las presas políticas en la cárcel de Villa Devoto (1974-1982): entre las disputas internas y los lazos de solidaridad
Authors: Ceballos Rocío
Published: March 2023

Con la recuperación de la democracia, la experiencia de la prisión política durante el genocidio argentino se ha visto opacada y relegada por el lugar destacado que cobraron los relatos centrados en testimoniar la topografía del horror y la represión. Este trabajo posee tres propósitos: reconstruir las políticas de resistencia que sostuvieron las presas, recuperar las contradicciones con las que se encontraron durante su encierro en la cárcel de Villa Devoto (1974-1983), y caracterizar el disciplinamiento sexo-genérico que soportaron durante la prisión política. Para esto nos apoyamos en testimonios disponibles en diversos archivos nacionales públicos y en bibliografía secundaria, en particular el trabajo “Nosotras, presas políticas”. Y sostenemos que las políticas de resistencia que las presas llevaron adelante en Villa Devoto fueron producto de la interacción entre los diversos conflictos internos y las prácticas de solidaridad.
Entre identificaciones étnicas y políticas: Lo judío dentro del campo “nacional y popular”
Authors: Setton Damián
Published: March 2023

El artículo analiza vínculos entre lo judío y el campo nacional y popular a partir de un estudio sobre la organización denominada Llamamiento Argentino Judío. Indaga en sus precedentes y en el contexto general de intersección entre lo político y lo judío que tiene lugar a fines del segundo gobierno de Cristina Fernández. Mediante la técnica de un análisis de documentos que apunta a la identificación inductiva de marcos, analiza los significados que el Llamamiento puso en circulación a través de sus primeras intervenciones públicas. Este análisis es complementado con entrevistas en profundidad realizadas a miembros del Llamamiento. Encontramos que las articulaciones entre etnicidad y política difieren de aquellas que tienden a observarse en la agenda de investigaciones. Más que la lucha por el reconocimiento de los derechoso el intento por visibilizar a un colectivo étnico, el Llamamiento se propone evidenciar las diferencias políticas que dividen al colectivo judío. La producción de esta imagen de lo judío se inserta en un contexto más amplio de lucha política a escala nacional. El estudio nos permite indagar en cómo los activistas del Llamamiento habitan los mundos étnico y político a partir de los mismos marcos cognitivos.
Formando subjetividades militantes. La función educativa del Movimiento de Sacerdotes para el Tercer Mundo en Mendoza, Argentina
Authors: Baraldo Natalia
Published: March 2023

Este artículo se propone abordar la dimensión pedagógica del Movimiento de Sacerdotes para el Tercer Mundo (MSTM) en la provincia de Mendoza, Argentina, durante el período 1967-1974. Se describen sus prácticas y opciones políticas, sus concepciones acerca de la concientización y una de las instancias sistemáticas de formación que algunos de sus miembros contribuyeron a conformar: el “Instituto para la Liberación y Promoción Humana”(ILPH). La investigación fue de carácter sociohistórico y se basó en fuentes orales y documentales. Entre los principales resultados se destaca la importancia del MSTM en el ámbito territorial, donde tuvo un rol organizativo/educativo fundamental. Además, su “opción por el peronismo” se concretizó en la pertenencia orgánica de un grupo significativo de sacerdotes, entre ellos sus principales referentes, al Peronismo de Base. Asimismo, sobresalió su rol pedagógico en la formación de subjetividades militantes, tarea que realizó de forma sistemática junto a cristianos/as protestantes a través del ILPH. Concluimos que la experiencia ecuménica delineó gran parte de la función educativa del MSTM y que los integrantes del mismo, o más ampliamente de la “constelación tercermundista”, desempeñaron el papel de intelectuales orgánicos en el proceso de constitución de una fuerza política alternativa al capitalismo, en los marcos del peronismo revolucionario.

OBJECTIVE

To evaluate the diagnostic, prognostic, and therapeutic utility of a cancer genomic diagnostic assay (SearchLight DNA; Vidium Animal Health) for diagnostically ambiguous cancer cases.

ANIMALS

69 privately owned dogs with ambiguous cancer diagnoses and for which the genomic assay was performed.

PROCEDURES

Genomic assay reports generated between September 28, 2020, and July 31, 2022, for dogs with malignancy or suspected malignancy were reviewed to determine the assay’s clinical utility defined as providing diagnostic clarity, prognostic information, and/or therapeutic options.

RESULTS

Genomic analysis provided diagnostic clarity in 37 of 69 cases (54%; group 1) and therapeutic and/or prognostic information in 22 of the remaining 32 cases (69%; group 2) for which the diagnosis remained elusive. Overall, the genomic assay was clinically useful in 86% (59/69) of cases.

CLINICAL RELEVANCE

To our knowledge, this was the first study to evaluate the multifaceted clinical utility of a single cancer genomic test in veterinary medicine. Study findings supported the use of tumor genomic testing for dogs with cancer, particularly those that are diagnostically ambiguous and therefore inherently challenging to manage. This evidence-driven genomic assay provided diagnostic guidance, prognostic support, and therapeutic options for most patients with an unclear cancer diagnosis that would otherwise have an unsubstantiated clinical plan. Furthermore, 38% (26/69) of samples were easily obtained aspirates. Sample factors (sample type, percentage of tumor cells, and number of mutations) did not influence diagnostic yield. Our study demonstrated the value of genomic testing for the management of canine cancer.
Finding the Path of the Jewish heroes in the Film
Authors:   Institute for Russian and Altaic Studies, CBNU, Kim Tae Ok
Published: March 2023

This article analyzes the journey of the three Jewish heroes in the film  directed by Liev Schreiber. It should be borne in mind that this film, which depicts the Holocaust and the life of Jewish exiles by a Jewish director, represents an inevitable connection and politics that cannot be separated from the director's life and worldview in any form of production process, story, and theme. In the beginning, the main protagonist of this film seems to be Jonathan, an American who visited Ukraine, but as the story develops, the person portrayed as important as, or even more important than, Jonathan is Alexander's grandfather. The memories and traditions of the two families, which transcend borders and last three generations, combined with the film's cyclical structure, show that it is impossible to disappear and be forgotten, and that they repeat forever, penetrating the past, present, and future. The film shows the life of an independent Ukraine and Ukrainian citizens like a landscape, and indirectly presents the oppression and massacre of Jews by Ukrainian nationalists and the Soviet government hidden behind the Nazi Holocaust. Although this film about the massacre of Jews in Ukraine in the 1940s was made in the 2000s, it is being recalled these days during the Russo-Ukrainian War. This can be said to show the historical common idea that the historical events of that time are still ongoing.

Authors:   Institute for Russian and Altaic Studies, CBNU, O.E. Kalinina
Published: March 2023

The problem of understanding such a phenomenon as business culture is one of the urgent problems facing modern science. The relevance of this problem is due to the fact that business ethics is necessary not only in the company's foreign economic relations, but also in building internal corporate relationships, the degree of development of which indicates the potential of building a rule of law state. The purpose of the study was to identify of patterns of development of business culture in the context of intercultural communications in the conditions of the region and Russia as a whole using certain research methods, which include: comparative approach, historical research methods, axiological approach. In the course of the study, the following conclusions were made: 1) modern science faces the problem of understanding the essence of business culture, its principles and conditions for the formation of Codes of Business Ethics both on the territory of individual regions and in relation to a specific business entity. At the same time, business culture should be understood as a system of guiding rules, norms of behavior stereotypes that operate in society, and are also inherent in economic entities, which affects the methods of implementing socio-economic activities of the organization; 2) the analysis of cross-cultural interaction shows that business cooperation of economic entities in the conditions of regional development is a socio-economic institution that regulates relations in the field of establishing mutually beneficial partnership constructive relations aimed at facilitating the development of ties between business entities by committing legals and factual actions by each party; 3) the standards of the company's business culture and the working principles of personnel policy will contribute to the motivation of staff, increase the business reputation of the company, and ultimately lead to constructive intercultural interaction as part of the implementation of the provisions of the Entrepreneur's Code of Business Ethics; 4) appealing to expert opinions of specialists, the atmosphere of friendly competition and discussion partnership, promoting the promotion of goods and services to domestic and world markets, informing about the establishment of close contacts with Russian and foreign partners, assistance in the preparation and holding of congress and exhibition and fair events contributes to effective intercultural communication in the region; 5) humanitarian expertise of socially significant projects of business entities will contribute to effective management decision-making, etc.
H2S Scavenger as A Universal Strategy to Deplete Bacteria-derived H2S for Antibacterial Sensitization
Authors: Gao Ye , Wang Xu , Wang Xia , Hu Ziwei , Liu Miao , Qiao Chunhua , Wang Yipeng , Ji Xingyue
Published: March 2023

Bacteria-derived H2S plays multifunctional protective roles against antibiotics insult, and H2S biogenesis pathway is emerging as a viable target for the antibacterial adjuvant design. However, the development of a pan-inhibitor against H2S-synthesizing enzymes is exceedingly challenging and severely underdeveloped. Herein, we propose an alternative strategy to downregulate the H2S levels in H2S-producing bacteria, which depletes the bacteria-derived H2S chemically by H2S scavengers without acting on the synthesizing enzymes. After the screening of chemically diversified scaffolds and a structural optimization campaign, a potent and specific H2S scavenger was successfully identified, which displayed efficient H2S depletion in several H2S-producing bacteria, potentiated both bactericidal agents and photodynamic therapy, enhanced the bacterial clearance of macrophages, disrupted the formation of bacterial biofilm and increased the sensitivity of bacterial persister cells to antibiotics. Most importantly, such an H2S scavenger exhibited very pronounced synergistic effects with gentamicin in a methicillin-resistant Staphylococcus aureus (MRSA) infected peritonitis mouse model. In aggregate, our results not only provided an effective strategy to deplete bacteria-derived H2S and firmly established the H2S biogenesis pathway as a viable target for persisters and drug-resistant bacteria, but also delivered a promising antibacterial adjuvant for potential clinical translation.
A Theory for Cavity Modified Ground-State Reactivities via Electron-Photon Interactions
Authors: Mandal Arkajit , Taylor Michael , Huo Pengfei
Published: March 2023

We provide a simple and intuitive theory to explain how coupling a molecule to an optical cavity can modify ground-state chemical reactivity by exploiting intrinsic quantum behaviors of light-matter interactions. Using the recently developed Polarized Fock States representation, we demonstrate that the change of the ground-state potential is achieved due to the scaling of diabatic electronic couplings with the overlap of the polarized Fock states. Our theory predicts that for a proton-transfer model system, the ground state barrier height can be modified through light-matter interactions when the cavity frequency is in the electronic excitation range. Our simple theory explains several recent computational investigations that discovered the same effect. We further demonstrate that under the deep strong coupling limit of the light and matter, the polaritonic ground and first excited eigenstates become the Mulliken-Hush diabatic states, which are the eigenstates of the dipole operator. This work provides a simple but powerful theoretical framework to understand how strong coupling between molecule and cavity can modify ground state reactivities.
Multi-domain Automated Patterning of DNA-Functionalized Hydrogels

Published: March 2023

DNA-functionalized hydrogels are capable of sensing oligonucleotides, proteins, and small molecules, and specific DNA sequences sensed in the hydrogels environment can induce changes in these hydrogels shape and fluorescence. Fabricating DNA-functionalized hydrogel architectures with multiple domains could make it possible to sense multiple molecules and undergo more complicated macroscopic changes, such as changing fluorescence or changing the shapes of regions of the hydrogel architecture. However, automatically fabricating multi-domain DNA-functionalized hydrogel architectures, which could enable the construction of hydrogel architectures with tens to hundreds of different domains. We describe a platform for fabricating multi-domain DNA-functionalized hydrogels automatically at the micron scale, where reaction and diffusion processes can be coupled to program material behavior. Using this platform, the hydrogels material properties, such as shape and fluorescence, can be programmed, and the fabricated hydrogels can sense their environment. DNA-functionalized hydrogel architectures with domain sizes as small as 10 microns and with up to 4 different types of domains can be automatically fabricated using ink volumes as low as 50 microliters. We also demonstrate that hydrogels fabricated using this platform exhibit responses similar to those of DNA-functionalized gels fabricated using other methods by demonstrating that DNA sequences can hybridize within them and that they can undergo DNA sequence-induced shape change.
Lithium Catalysed Sequence Selective Ring Opening Terpolymerisation: A Mechanistic Study
Authors: Deglmann Peter , Machleit Sara , Gallizioli Cesare , Rupf Susanne , Plajer Alex
Published: March 2023

The catalytic construction of well-defined materials from mixtures of building blocks is an important challenge in sustainable catalysis. In this regard, we have recently reported a new type of selective ring-opening terpolymerisation (ROTERP), in which three monomers (A, B, C) are selectively enchained into a (ABAC)n sequence, but the reasons behind this unusual selectivity remained unanswered. In this study, we present a detailed investigation into the full ROTERP mechanism based on the reactivity of model intermediates, computational studies investigating >100 possible intermediates and transition states and reaction kinetics. Experimental verification of the intermediate speciation, the primary insertion steps and the side-reactions lets us show that although most insertions and side-reactions are thermodynamically viable, kinetic selection processes at the propagating chain end determine the sequence selectivity. Computational studies elucidate the special role and speciation of the Lithium catalyst which during the catalytic cycle involves mono-metallic, bi-metallic and charge separated transitions states comprising both coordinative activation of incoming monomers and functional groups of the polymer backbone adjacent to the propagating chain. Our study not only deciphers the mechanism of a rare selective terpolymerisation but also helps answering open questions relevant to ring-opening copolymerisation (ROCOP) and alkali-metal catalysis in general, thus guiding the design of future polymerisation catalysis for degradable materials.

Income poverty and sectoral income differentials in Chilean agricultural (1935–1968)
Authors: Casanova Mauricio
Published: March 2023

The main aim of this study is to analyse sectoral income differentials and income poverty in Chilean agricultural between 1935 and 1968. The food share method of the United Nations Economic Commission for Latin America and the Caribbean (ECLAC) is used as a methodological approach. The conclusions are as follows: (1) contrary to what the existing literature suggests, the Chilean agricultural sector was not entirely an agrarian subsistence economy; (2) the cost of agricultural labour began to increase in the mid-1930s, but less than in the industrial and manufacturing sectors in urban areas; (3) maintaining tenants above the poverty line in rural areas from 1935 to 1955 was as expensive as paying the average wage of blue-collar workers; and (4) if days worked per year and household size are considered, agricultural wages rose but remained below the poverty line for rural areas.

Authors: Sprikut R. V. , Maznichevsky A. N.
Published: March 2023

A technology for production of special steels of a given chemical composition for reference samples is considered. The developed technology includes smelting of the steel (alloy) of a given composition in a vacuum induction furnace using high purity charge materials followed by forging of the ingot in several stages on hammers with a mass of the falling part 7 and 3 tons and rolling on a universal mill 250 into finished bars. Alloys of several grades were preliminarily smelted in a laboratory vacuum induction furnace in accordance with the chosen scheme of metal microalloying and then subjected to hot deformation and hot plasticity tests. The hot plasticity was evaluated on a plastometer designed by the Research Institute of Metallurgy (Chelyabinsk). The data obtained during the research made it possible to adjust the technology of smelting (by optimization of the amount of microalloying elements) and hot deformation of metal (by the choice of heating temperature for forging) in conditions of pilot production. This technology was repeatedly used to obtain metal products which formed a base for reference samples of LG32 - 36, LG56 - 64, NG15 -17 series and some others manufactured at the Institute for Certified Reference Materials (Yekaterinburg). The developed technique ensures a high purity of the produced metal in terms of dissolved gases, harmful impurities and non-metallic inclusions, which made it possible to provide the customer with high-quality metal in a short time frame.

Investigating the impact of eye movement desensitization and reprocessing (EMDR) in reducing birth trauma symptoms
Authors: Wetherell Silvia
Published: March 2023

Background: Childbirth-related traumatic experiences are an overlooked area of psychological suffering, often leading to Post-Traumatic Stress Disorder, Perinatal Mood and Anxiety Disorders, and difficulties in bonding between mother and baby. This study aimed to evaluate the effectiveness of Eye Movement Desensitization and Reprocessing as a brief psychological intervention in reducing Birth Trauma symptoms.

Methodology: Using a prospective experimental longitudinal design, 12 women residing in Singapore with Birth Trauma symptoms received three 90-minute eye-movement and desensitization (EMDR) sessions over two weeks on average. Participants were assessed through two trauma self-report questionnaires and underwent a brief Autonomic Nervous System (ANS) assessment.

Results: Post-treatment assessment showed significant differences in mean trauma scores with a 76% reduction on the Modified Perinatal PTSD Questionnaire (z = -3.061, p = .002) and 70% reduction on the Impact of Event Scale Revised (z = -3.061, p = 0.002). Skin conductance response changes from baseline to stressor reduced by 4% but were not statistically significant (z = -.863, p = 0.39).

Conclusion: Brief EMDR has shown promise as an effective treatment for Birth Trauma. Larger controlled randomized studies are required to evaluate the effectiveness of EMDR when compared to a placebo control group.

Background: Metabolic syndrome is the challenge of this era; diseases are initiated with the abnormal functioning liver. This study aims to evaluate the effects of HFD on liver anatomy and to study the morphological changes with its histological findings

Methodology: 50 male albino rats were acclimatized in the animal house of DUHS, divided into 5 groups (GP). GP 1 was on a standard diet for 6 weeks, GP 2 was on HFD for 6 weeks, GP 3, GP 4, and GP 5 were on HFD for 6 weeks. They were treated with ginseng root extract in doses of 100mg/ml, 200mg/ml and 400 mg/ml for 6 weeks. After 12 weeks, GP3, GP4, and GP 5 were dissected, and the liver was isolated for histology and micrometry. Blood was drawn and sent for LFT to correlate morphological changes with enzymes.  

Results: Rats on a high-fat diet developed fatty liver with altered LFT. The treated group showed a reversal of changes in morphology and LFT in a dose-dependent manner.

Conclusion: The morphometric analysis revealed that fatty accumulation in liver cells deranges the liver function leading to metabolic syndrome. Ginseng root extract helps in depleting fatty accumulation in the liver.
