The work summarizes the results of testing the technology for preparing a bifunctional cobalt catalyst for the synthesis of hydrocarbons from CO and H2, obtained by extruding a mixture of Co-Al2O3 /SiO2 catalyst powders and HZSM-5 zeolite with a binder – boehmite in industrial conditions (2 batches of 50 kg each were prepared). The catalyst technology was implemented on the equipment of Ishimbay Specialized Chemical Catalyst Plant LLC. The obtained industrial samples of the catalyst were characterized by XRF, TPR H2, DTG, and tested in the synthesis of hydrocarbons from CO and H2 at a temperature of 250 °C, a pressure of 2.0 MPa, GHSV 1000 h–1. It has been shown that the implementation of the technology of a bifunctional cobalt catalyst for the production of low pour point diesel fuel in industrial conditions makes it possible to reproduce the characteristics of the catalyst obtained in laboratory conditions. The technology for producing the catalyst can be recommended for the production of industrial batches. It was determined that changes in the heat treatment conditions of the catalyst, as well as the presence/absence of a peptizer and pore former do not lead to a significant decrease in the productivity of C5+ hydrocarbons. The contentof the diesel fraction in C5+ products obtained from industrial samples of the catalyst remains at the level of the value obtained from the laboratory sample of the catalyst. At the same time, the low-temperature properties of diesel fuel obtained using all catalyst samples have similar values. Using an industrial sample synthesized without the use of a peptizing agent and a pore-forming component, the best lowtemperature properties of diesel fuel were achieved – the cloud point and fluid loss point were minus 16 and minus 24, respectively.

Publicación de la ‘Colección Villasante de cantos y música tradicional ashaninka (1981- 1985)’ y proyecto de investigación
Authors: Villasante Cervello Mariella 
Published: January 2024

Como en todas las sociedades de cazadores-recolectores, las creencias asociadas al mundo espiritual y las artes musicales son muy importantes entre los Ashaninka, los Nomatsiguenga y todos los pueblos originarios amazónicos. Esas temáticas han sido muy poco estudiadas en antropología social. Además, actualmente el abandono relativo de las lenguas originarias implica la disminución de la transmisión de las creencias y de las músicas que representan lo esencial del patrimonio cultural ashaninka. En ese marco, mi investigación actual tiene por objeto esclarecer la evolución de la relación entre la producción musical, las creencias y la identidad étnica y, paralelamente, revalorizar el patrimonio musical y mitológico de los Ashaninka y sus identidades étnicas. El punto de partida de este estudio de antropología social y musical son los cantos que he recogido entre 1981 y 1985, Colección Villasante de música tradicional ashaninka archivada en el Centre de Recherches d’Ethnomusicologie (CREM, Francia), que presento en esta nota.

Published: January 2024

This research aims to discuss the relationship between Artificial Intelligence (AI) and law. The emergence of the idea of using AI as a tool to analyse judges' decisions has generated mixed responses. On the one hand, the use of AI can be used as a tool to objectively ensure legal certainty, but on the other hand the use of AI can displace the legal supremacy of judges in court. This attracts the author's attention to examine the use of AI in analysing legal cases and as a consideration for judges in deciding polygamy cases. Polygamy itself is a very complex case in court. Judges' considerations in deciding polygamy cases do not only consider procedural aspects, but also involve substantial aspects related to the cumulative and alternative conditions of polygamy. As a chatbot-based platform, AI certainly has limited access in analysing the legal complexity in polygamy cases. This research focuses on the analysis of AI in analysing polygamy cases both in terms of legal basis and justice. This research method is normative with a conceptual legal approach, data is obtained by netnography using the ChatGPT/OpenAi platform and analysed using the content analysis method. The results showed that there were two aspects that were considered by the judge in the AI version of the polygamy case. First, the juridical aspect which is based on the polygamy provisions in the Compilation of Islamic Law. The second aspect is the social aspect based on gender justice. In addition to presenting the essence of several laws and regulations, AI also provides complex social analyses with a gender justice perspective with simple and straightforward sentences. However, this does not mean that AI can be an absolute and stand-alone consideration in polygamy licence cases. AI is only a complement that makes it easier for judges to analyse cases. This is because the judge's involvement in cognitive and psychological aspects is still needed in interacting with litigants in court.

English course books are one of the main elements determining the success of the English teaching-learning process to meet the pre-determined objectives. Currently, the teachers of, English in Indonesia face a complicated tasks in choosing suitable English teaching materials in die form of English course books. The purpose of the article is to discuss an appropriate way to choose English course books suitable with the students' socio-economic cultural backgrounds to facilitate students' learning. The intended way is that the teachers of English do an empirical evaluation of the course books they are using, a retrospective evaluation. The evaluation can be done through either macro or micro evaluation. The tangible and practical evaluation to do is a micro evaluation in which the teachers of English retrospectively and thoroughly evaluate certain parts of the English course books representing the whole content The criteria to valuate include goals, students' backgrounds (topics and vocabulary related to students' lives), cultural acceptability, language skills to develop quality of practical materials in the classroom (activating students' participation), roles, sequencing of the materials (procedure), formats, instructions, and visualization. If the teachers of English find out such English course books through their evaluation, they can use the course books in the following terms. It a wise way to choose English course books to be used to optimally reach the pre-determined objectives. If the teachers of English do not find such suitable English course books through their evaluation, they can add materials to or reduce the content of the course booksand finally they will have teachers' edition English teaching materials.
Comprehending Assimilation Pattern by Tracing Its Phonological Process: Input, Environment, and Process
Authors: Sadiq Nizamuddin 
Published: January 2024

Native speakers, English mother tongue, speak naturally. Although they do not think the way how they are pronouncing words, they seem to simplify their speeches-Therefore, it is often difficult to understand what is spoken by them because it is heard like babbling. One of the simplifications of speeches is assimilation. Assimilation is one of phonological processes. Comprehending its phonological process means understanding its input, environment, and process. Therefore, all phenomena of pronunciation particularly assimilation are collected and then they are classified and described one by one based on its input, environment and process. The result of the research is that to anticipate the preceding word, the first is anticipating the preceding: a) when alveolar is preceded by bilabial, alveolar will anticipate the bilabial by changing alveolar into bilabial, b) when alveolar is preceded by velar, alveolar will anticipate the velar by changing alveolar into velar, c) when alveolar is preceded by palato alveolar, alveolar will anticipate by changing into palato alveolar.
A Portrayal of Victorian Men And Women As Seen In O'neill's “The Grand Match”
Authors: Kurnia Nandy Intan 
Published: January 2024

ABSTRACT This paper analyzes the portrayal of Victorian women and men in the poem of Moira O'Neill, entitled “The Grand Match”. The poem gives the description of men and women relationship related to the discussion of love and marriage. As one of Victorian female poets, O'Neill tries to satirize the relationship of women and men by portraying the love story of a stereotypical male fortune seeker, who marries a rich woman and denies his own feeling toward a young-charming woman. This study is an attempt to show that O'Neill's female characters are not typically women commonly found in a literary text during the era in which it was written. In many ways they position themselves as a complete break from the traditional stereotyping of women, and they even can be seen as the representation of “New Woman”. In addition, through this study, the readers would be able to broaden their perspectives that although the Victorian Age was known as the era of prose, there are a lot of poems worth reading.
Sex-Specific Effects of Long-Term Antipsychotic Drug Medication on Adipocyte Tissue and the Crosstalk to Liver and Brain in Rats
Authors: Fehsel Karin , Bouvier Marie-Luise 
Published: January 2024

Antipsychotic drug (APD) medication can lead to metabolic dysfunctions and weight gain, which together increase morbidity and mortality. Metabolically active visceral adipose tissue (VAT) in particular plays a crucial role in the etiopathology of these metabolic dysregulations. Here we studied the effect of 12 weeks drug medication by daily oral feeding of clozapine and haloperidol on the perirenal fat tissue as part of VAT of male and female Sprague Dawley rats in the context of complex former investigations on brain, liver, and blood. Adipocyte area values were determined as well as triglycerides, non-esterified fatty acids (NEFAs), glucose, glycogen, lactate, malondialdehyde equivalents, ferric iron and protein levels of Perilipin-A, hormone-sensitive-lipase (HSL), hepcidin, glucose transporter-4 (Glut-4) and insulin receptor-ß (IR-ß).
We found increased adipocyte mass in males with slightly higher adipocyte area values in both males and females under clozapine medication. Triglycerides, NEFAs, glucose and oxidative stress in the medicated groups were unchanged or slightly decreased. In contrast to controls and haloperidol medicated rats, perirenal adipocyte mass and serum leptin levels were not correlated under clozapine. Protein expressions of perilipin-A, Glut-4 and HSL were decreased under clozapine medication. IR-ß expression changed sex-specifically in the clozapine medicated groups associated with higher hepcidin levels in the perirenal adipose tissue of clozapine-medicated females.
Taken together, clozapine and haloperidol have a smaller effect than expected on perirenal adipose tissue. The perirenal adipose tissue shows only weak changes in lipid and glucose metabolism. The main changes can be seen in the proteins examined and probably in their effect on liver metabolism.

Published: January 2024

The high reactivity of acetylene group the formation of strong chemical bonds with active sites on mineral surfaces, thereby improving the flotation performance of gold minerals. This study utilized Density Functional Theory (DFT) to analyse the quantum chemical parameters of structure, Mulliken population, and the frontier orbitals of a thioester collector containing an acetylene group, PDEC (prop-2-yn-1-yl diethylcarbamodithioate). PDEC is compared with analogous thioester collectors Z-200 and Al-DECDT, and the interaction mechanism of PDEC on the Au(1 1 1) surface is simulated, followed by empirical validation through adsorption experiments. The findings indicate that S atom of PDEC in the carbon-sulfur group exhibit shorter covalent bond lengths, and reduced carbon-sulfur double bonds and Mulliken population, resulting in enhanced electron localization. This confers greater selectivity to PDEC during its adsorption on mineral surfaces. Frontier orbital analysis shows that the electrons of acetylene group possess a notable electron-accepting capacity, significantly influencing frontier orbital energy of PDEC and playing a pivotal role in the bonding interaction with mineral surfaces. Both the S atom in carbon-sulfur group and its acetylene group establish stable adsorption structures with the A(111) surface in a single coordination mode. The adsorption energy sequence is PDEC &gt; Al-DECDT &gt; Z-200. Partial density of states demonstrates that S 3p orbit of carbon-sulfur group hybridize with Au 5d orbit, while the C 2p orbit of the acetylene group engage in weaker back-donation bonding with Au 5d orbit. This is corroborated by electron density difference and post-adsorption Mulliken population analyses, revealing that S atom of carbon-sulfur group in PDEC donate electrons to Au atom, forming dominant positive coordination bonds, whereas the acetylene group accepts partial electrons from Au atom, resulting in weaker back-donation bonds. The adsorption experiments align with the DFT adsorption energy results.
Advancing Lithium Battery Performance through Porous Conductive Polyaniline-Modified Graphene Composites Additive
Authors: Lin Hao Tung , Chuang Eunice , Lin Sheng Chun 
Published: January 2024

This study is dedicated to enhancing lithium battery performance through the utilization of porous conductive polyaniline-modified graphene composites (PMGC). Given the growing importance of green energy, coupled with the development of lithium-ion battery systems and electric vehicles, achieving high-speed charge and discharge performance has become imperative. Traditional approaches involve incorporating additives like carbon nanotubes and graphene into electrodes to improve conductivity, but they encounter challenges related to cost and aggregation issues. In this study, polyaniline (PANI), a cost-effective, stable, and conductive polymer, was explored. PMGC was formed by employing ammonium persulfate (APS) as an oxidant during PANI polymerization, simultaneously serving as a surface modifier for graphene.
The study systematically investigated the impact of varying amounts of PMGC on lithium-ion battery electrodes, assessing reductions in internal resistance, aging effects, different charge and discharge rates, and cycle performance. PMGC exhibited a porous structure formed by nanoscale PANI intertwining on graphene. Various measurements, including FT-IR, TGA, Raman spectroscopy, and battery performance assessments, confirmed the successful synthesis and positive effects of PMGC.
Results indicated that a 0.5% addition of PMGC led to reduced internal resistance and enhanced fast charging and discharge capacity. However, excessive PMGC adversely affected aging and self-discharge. The study provides valuable insights into optimizing PMGC content for improved lithium battery performance, presenting potential advancements in energy storage systems and electric vehicles.

Published: January 2024

Background:
Lower-extremity fractures (LEFs) account for >30% of all skeletal injuries, contributing to the global health and economic burden. Fracture epidemiology in the Middle East and North Africa (MENA) region has been studied little. Health factors and disease epidemiology differ greatly among populations in MENA despite cultural, political, and economic similarities among the region’s countries. This study examined the epidemiology of LEFs and the need for rehabilitation in MENA from 1990 to 2019.

Methods:
We examined the epidemiology of fractures of the pelvis, hip, femur, patella, tibia, fibula, ankle, and foot bones using Global Burden of Disease (GBD) data. Fracture incidence, counts, and rates were measured for males and females across age groups in the 21 MENA countries as identified by the GBD data set. Associations between years of healthy life lost due to disability (YLD) resulting from fracture and the Socio-demographic Index (SDI) were analyzed.

Results:
In contrast to the global trend, the age-standardized incidence rate (ASIR) of LEFs in the MENA region increased by 4.57% from 1990 to 2019. In 2019, the highest ASIR among fractures was attributed to fractures of the patella, fibula, tibia, or ankle (434.36 per 100,000), most frequently occurring among those 20 to 24 years of age. In 2019, the highest ASIR of all fractures was noted in Saudi Arabia (2,010.56 per 100,000) and the lowest, in Sudan (523.29 per 100,000). The greatest increases from 1990 to 2019 in the ASIR of LEFs were noted in Yemen (132.39%), Syria (107.27%), and Afghanistan (94.47%), while the largest decreases were found in Kuwait (−62.72%), Sudan (−48.72%), and Iran (−45.37%). In 2019, the YLD rate of LEFs had increased to 277.65 per 100,000, up from 235.55 per 100,000 in 1990.

Conclusions:
Between 1990 and 2019, LEFs increased in the MENA region. Violence, war, and road traffic accidents increased, leading to a high rate of fractures, especially among youth. Low bone-mineral density related to vitamin D deficiency has also been reported as a risk factor for fracture in the region. Regional health authorities should be informed of fracture patterns by this study.

UMPL- VINS: Generalized SLAM with Point and Line Features for Multi-scene Applications
Authors: Jiang Hao , Shang Yilin , Xue Shan , Guo Dongsheng , Zhang Weidong 
Published: January 2024

Abstract
The use of line features to improve the localization accuracy of visual inertial SLAM (VINS) based on point features is of increasing interest because of the additional constraints they provide on the scene structure. It is found that although the introduction of line features improves the accuracy of relative position estimation in some scenes due to the additional constraints, the two constraints only achieve an equalization for the estimated relative position. Therefore, in some environments two constraints can reduce the accuracy of the single-feature constraint algorithm and also make the real-time performance of the system more challenging. To address such issues, in this paper, we design a generalized SLAM system with point-line features that can be applied to multiple scenarios. We first enhance the image frames used for feature extraction by eliminating motion blur frames through the fuzzy metric method and mutation modeling of velocity and rotation. Then we improve the traditional line detection model by short line fusion, uniform distribution of line features, and refinement of edge features to obtain high-quality line features for building SLAM. Finally, based on the application of point features and line features for different scenes, a point and line feature separation-union model is proposed. In addition, we design a transformation model for line-point features to enhance the processing of point-line features. Experimental results on EuRoc, TUM_VI, KITTI, PennCOSYVIO and our own recorded dataset prove that the method proposed in this paper realizes a generalized SLAM with point and line features applied to multi-scenes with good advantages.
Isolation and characterization of lytic bacteriophages from various sources in Addis Ababa against antimicrobial-resistant diarrheagenic Escherichia coli strains and evaluation of their therapeutic Potential
Authors: Sada Tamirat Salile , Tessema Tesfaye Sisay 
Published: January 2024

Abstract
Background
Escherichia coli is a common fecal coliform, facultative aerobic, gram-negative bacterium. Pathogenic strains of such microbes have evolved to cause diarrhea, urinary tract infections, and septicemias. The emergence of antibiotic resistance urged the identification of an alternative strategy. The use of lytic bacteriophages against the control of pathogenic E. coli in clinics and different environmental setups (waste and drink water management) has become an alternative therapy to antibiotic therapy. Thus, this study aimed to isolate and characterize lytic bacteriophage from various sources in Addis Ababa, tested them against antimicrobial-resistant diarrheagenic E. coli strains and evaluated their therapeutic potential under in vitro conditions.
Methods
A total of 14 samples were processed against six different diarrheagenic E. coli strains. The conventional culture and plaque analysis agar overlay method was used to recover lytic bacteriophage isolates. The phage isolates were characterized to determine their lytic effect, growth characteristics, host range activity, and stability under different temperature and pH conditions. Phage isolates were identified by scanning electron microscope (SEM), and molecular techniques (PCR).
Results
In total, 17 phages were recovered from 84 tested plates. Of the 17 phage isolates, 11 (65%) were Myoviridae-like phages, and 6 (35%) phage isolates were Podoviridae and Siphoviridae by morphology and PCR identification. Based on the host range test, growth characteristics, and stability test 7 potent phages were selected. These phages demonstrated better growth characteristics, including short latent periods, highest burst sizes, and wider host ranges, as well as thermal stability and the ability to survive in a wide range of pH levels.
Conclusions
The promising effect of the phages isolated in this study against AMR pathogenic E. coli has raised the possibility of their use in the future treatment of E. coli infections.
