Ukraine, ideology, and arms: Coming to terms with just war theory
Authors: Sørensen Asger
Published: October 2024

The Russian invasion of Ukraine has challenged the ideals of peace that I and many other left-wing critical intellectuals hold dear. By the end of the 18th century, Immanuel Kant argued that the realist law of peoples and the idea of just war should be superseded by the idea of perpetual peace, and, fortunately, the principled opposition to war was institutionalized in the United Nations in the 20th century. However, when the aggressor has already taken possession of huge swathes of territory, calls for peace may be suspected of ideological bias. The right to defend yourself is almost universally recognized, but a military counter-offensive to reconquer lost territory is not merely defense but itself aggression, and thus an act of war. Many of us, however, want to support such efforts in Ukraine, and what is worrying is that this places us on a slippery slope, reopening the possibility of justifying war. As I will argue, this is nevertheless the path we must take, thus accepting the possible justification of war and the possible justification of specific activities and armaments but not others. We should take more seriously the justice of war, with all the specific normative challenges that this implies.
Contemporary Relationships: The Potential Risk of Affection and Suicidal Ideation
Authors: Kumar Yadav Pradeep
Published: October 2024

Introduction: Modern relationship dynamics, influenced by factors such as social media, changing gender roles, and societal expectations, have given rise to unique challenges in understanding the intersection of love addiction and suicide risk. This introduction sets the stage for thoroughly examining existing research, highlighting the need to address this pressing issue and its potential implications for mental health interventions. Aim: This article analyzes contemporary relationships, revealing their potential link to increased vulnerability to suicidal thoughts in modern romantic relationships, fostering a nuanced understanding. Methodology: This study explores the relationship between love, affection, and suicidal tendencies using NCRB data and relevant literature. Contemporary relationship dynamics were examined, with case studies included for support. Studies were critically appraised for quality, ensuring robust conclusions on how emotional factors influence suicidal behavior in modern relationships. Result: NCRB data from 2020-2022 reveals a 4.5% rise in suicides due to 'Love Affairs,' contributing to a total of 170,924 suicides in 2022. This highlights the increasing impact of romantic relationships on mental health, particularly among young adults and minors. Conclusion: Contemporary relationships have become increasingly complex, with affection as both a source of joy and a potential risk factor for emotional distress. While affection fosters emotional support and connection, it can also increase vulnerability to psychological pain due to unreciprocated love, conflicts, or neglect. This study highlights the link between love addiction and suicidal tendencies, emphasizing the influence of digital communication on unrealistic expectations. It calls for collaborative efforts among mental health professionals, educators, and policymakers to raise awareness and promote healthier relationship norms and coping mechanisms.
The Advances in Gene Therapy Research for Huntington’s Disease
Authors: Sun Joey , Fan Xiujun
Published: October 2024

Huntington's Disease (HD) is a debilitating neurodegenerative disorder characterized by progressive motor dysfunction, cognitive decline, and psychiatric symptoms, resulting from the expansion of CAG repeats in the HTT gene. The aggregation of mutant huntingtin (mHTT) protein is central to HD pathogenesis, leading to widespread neuronal dysfunction and eventual cell death. Advances in in vitro modeling and drug screening methodologies have significantly contributed to understanding and potentially mitigating HD's effects. In vitro models, particularly those involving induced pluripotent stem cells (iPSCs), enable detailed exploration of HD's molecular mechanisms, facilitating the development of targeted therapeutic strategies. The integration of these approaches, alongside comprehensive timelines detailing the disease's progression and intervention windows, is summarized in this review in the light of providing systematic info for advancing the development of effective treatments.

Printing and publishing in Saigon-Cho Lon, Vietnam: Catalysts of colonial social and cultural transformation
Authors: Thong Duong Thanh
Published: October 2024

In 1859, the French invasion of Gia Dinh marked the beginning of their acquisition of Cochinchina. Shortly after their arrival, France brought printers on their ships, along with firearms and artillery. The printers were intended to quickly disseminate the policies of the invading army to the inhabitants of the occupied territory. At the end of 1861, the inaugural official newspaper in Cochinchina, ‘Le Bulletin officiel de l’expédition française de la Cochinchine’, had been published. The Royal Printing House (l’Imprimerie Impériale), the first printing facility in Cochinchina, was also established at the end of 1861 to accommodate printing tasks, particularly the production of gazettes. In 1873, various private printing houses emerged in Saigon-Cho Lon. Printing and publishing efforts gradually assimilated into the social fabric of Cochinchina after serving as a tool of the invaders. They transformed into political and cultural institutions within colonial society, notably in Saigon-Cho Lon. The progression of these activities during the process was observable, at least for those granted permission to participate. The requirements of the colonial environment and the vitality of the private sector fuelled these new activities, although the colonial authorities deemed it necessary to exert control over them. This article offers additional information on the printing and publishing activities in Saigon-Cho Lon, Vietnam, highlighting the accomplishments of some distinguished printers.
Age of neutering contributes to risk of cruciate ligament rupture in Labrador Retrievers
Authors: DeForge Teagan L. , Momen Mehdi , Conidi Gabi , Muir Peter , Sample Susannah J.
Published: October 2024

OBJECTIVE

Cruciate ligament rupture (CR) in Labrador Retrievers is a complex polygenic disease with high heritability. The environmental contribution to CR risk remains poorly characterized. An accurate genetic risk test for CR in the Labrador Retriever has been developed. This enables evaluation of environmental risk with knowledge of genetic disease predisposition through study of dogs with phenotypic disease status that is discordant with their genetic risk. The objective of this study was to identify environmental factors that contribute to CR in Labrador Retrievers through evaluation of dogs with clinical phenotypes that are discordantly predicted with the use of genetic markers.

METHODS

Dogs were prospectively recruited between January 2013 and December 2022. To study discordant subjects, case dogs with a posterior risk probability value < 0.75 and control dogs with a posterior risk probability of > 0.25, determined with the use of an average of 8 statistical models, were selected. The environmental factors investigated were neuter status, age of neuter, withers height measured at the dorsal-most ridge between the scapulae, weight, body mass index, and athletic activity.

RESULTS

Ninety three dogs were discordant: 58 dogs were discordant CR cases, and 35 dogs were discordant CR controls. Neutering before 12 months of age was a significant risk factor for CR development. Sex, neuter status, or status as an athlete was not associated with CR risk.

CONCLUSIONS

Neutering before 12 months of age influences risk of CR in Labrador Retrievers.

CLINICAL RELEVANCE

This information can inform management decisions about Labrador Retrievers regarding age of neutering, body condition, and athletic activity. The primary factor influencing CR development in Labrador Retrievers is polygenic intrinsic genetic risk.

Household Well-Being, Environment and Health in the Peripheries of the Metropolitan Area of Oaxaca City
Authors: Reyes-Morales Rafael Gabriel , Gijón-Cruz Alicia Sylvia , Martínez Verónica Judith Yescas
Published: October 2024

Objective: The economy of poor urban households is analyzed using a well-being function that also considers incomes, sociodemographic characteristics (CS), housing and the environment.
 
Theoretical structure: The dependent variable is household well-being (BF) and the explanatory variables are all incomes obtained from the market economy, as well as government transfers (TG). The CS represent resources that facilitate obtaining income; housing provides income indicators; and the environment are the physical conditions that determine the state of health.
 Methodology: A probabilistic survey was applied to a sample of households in four poor peripheral neighborhoods. The equations were constructed using ordinary least squares regression and the beta coefficients measure the contribution of the variables from the four categories above to the BF. The effects of these variables on health expenditure (GS) are also measured.
 
Discoveries: The main incomes that contribute to the BF were determined and these make a contribution equivalent to that of the set of variables of the CS, housing and family businesses. Likewise, the environment and diseases increase GS.
 
Practical and social implications: Research shows that poor peripheral urban households participate in the market economy and that an increase in average age contracts their level of BF.
 
Originality/value: The tested model turned out to be versatile and accurate in analyzing the economies of poor urban households and has greater explanatory power than the agricultural household models and the applied general equilibrium model.

Pharmacological Activity of Plant Extracts in Self-Nanoemulsifying Drug Delivery System Dosage Form: Narrative Review
Authors: Julio Ivan , Zubair Muhammad Sulaiman , Syukri Yandi
Published: October 2024

The utilization of medicinal plants as therapeutic agents has obstacles to achieving the target action due to their low solubility. Self-Nanoemulsifying Drug Delivery System (SNEDDS) is a method developed to increase the solubility of poorly water-soluble substances, such as medicinal plant extracts. This review aims to present a narrative overview of the potential utilization of SNEDDS in enhancing the pharmacological activity of plant extracts. Article searches were conducted on several websites, such as Google Scholar, PubMed, and ScienceDirect. Literature studies showed that the use of SNEDDS formulations in several medicinal plants such as dayak onion, soursop leaf, papaya leaf, bay leaf, kale, sidaguri, black cumin, mangosteen peel, harendong, pineapple peel, and cocoa is more effective than the administration of extracts alone because it can increase the solubility and bioavailability of a compound. Pharmacologically, SNEDDS shows its success in enhancing antioxidant, anti-inflammatory, analgesic, antidiabetic, antihyperglycemic, antimalarial, immunostimulant, antimicrobial, anticancer, wound healing, and hepatoprotective activities in various plant extracts. The utilization of SNEDDS formulations in plant-based drugs has a positive impact on the advancement of drug therapy, especially for compounds that have low solubility.
Analysis of Al-‘Arabiyyah Lil Hayah Books as Teaching Material from the Perspective of Brian Tomlinson and Hitomi Masuhara’s Theory
Authors: Rasyidah Nafiatur , Nurdinsyah Muhammad Maulana , Uqba M Sholih Salimul , Ma'ali Abul , Ibrahim Faisal Mahmoud Adam
Published: October 2024

Teaching materials are crucial in the learning process, especially in Arabic language acquisition. "Al-'Arabiyyah Lil Hayah" serves as a reference guide for new students enrolled in the Special Program for Arabic Language Development (PKPBA) at UIN Maulana Malik Ibrahim Malang, providing a structured approach to enhance Arabic language skills across various academic disciplines. This study analyzes the book through the lens of the theory of different levels of teaching materials proposed by Brian Tomlinson and Hitomi Masuhara. Utilizing a literature study with a qualitative approach, data were collected through documentation techniques and analyzed using the Miles, Huberman, and Saldana model, which includes data condensation, presentation, and conclusion drawing. The findings indicate that the four volumes of "Al-'Arabiyyah Lil Hayah" largely align with the recommendations of Tomlinson and Masuhara at basic, intermediate, and high levels. However, certain gaps remain, notably the absence of a comprehensive comprehension approach in Volume 1 and a deficiency in extensive reading and listening activities in Volumes 2 and 3. Additionally, Volume 4 lacks real-world professional language use materials, such as newspapers and research reports, which are essential for high-level learners. These shortcomings highlight a disconnect between the theoretical framework and the practical needs of students. Consequently, this research underscores the need for future studies to conduct a more thorough analysis of the suitability of the content, learning activities, and instructional approaches utilized in "Al-'Arabiyyah Lil Hayah," ensuring they effectively address the specific needs and characteristics of students at UIN Maulana Malik Ibrahim Malang.

ИСПОЛЬЗОВАНИЕ ГАЛОИДУГЛЕВОДОРОДА ДЛЯ ДИСТАНЦИОННОГО ТУШЕНИЯ ПОЖАРОВ В ТУПИКОВЫХ ВЫРАБОТКАХ ШАХТ
Authors: Голик А.С. , Попов В.Б. , Сачков А.В. , Махмудова К.К.
Published: October 2024

Возникновение пожаров в метанообильных тупиковых выработках, как правило, сопряжено с постоянной потенциальной опасностью взрывов газовоздушных смесей при открытом устье выработки или при изоляции тупика. Тушение пожара здесь значительно сложнее, так как подход к очагу пожара возможен только с одной стороны -- навстречу исходящим горячим пожарным газам. Практически редко удается проникнуть к очагу в тупиковой выработке и непосредственно воздействовать огнегасительными средствами. Поэтому проблема дистанционного тушения пожаров в тупиковых выработках является весьма актуальной. Для тушения подземных пожаров применяются галоидуглеводороды бромистый этил, фреон 114В2 (тетраортодибранэтан) и их смеси. Дистанционно в очаг пожара в тупиковой выработке фреон 114В2, наименее токсичный галоидуглеводород, возможно подавать в спутном потоке воздуха по вентиляционному трубопроводу.

As a rule, the occurrence of fires in methane-rich dead-ends is associated with a constant potential danger of explosions of gas-air mixtures at the open mouth of the mine or at the insulation of the Tu-peak. Extinguishing the fire is much more difficult, since the approach to the fire is possible only from one side -- towards the outgoing hot-hot gases. Almost rarely it is possible to penetrate to the hearth in a dead-end development and directly affect the fire extinguishing agents. Therefore, the problem of remote fire extinguishing in dead-end workings is very urgent. To extinguish underground fires used halocarbons ethyl bromide, freon 114B2 (Tetra ortho di-bromatan) and mixtures thereof. Distantly, the fire in a dead-end development of freon 114B2, the least toxic galoiduglyerodov may serve in concurrent flow of air through the ventilation duct.

В настоящей статье приводятся данные о волноводных свойствах угольного массива при полном внутреннем отражении сейсмических волн от промышленных взрывов на границе раздела угольного пласта и вмещающих пород. Рассматривается вопрос об устойчивости подготовительных выработок, расположенных вблизи мест взрывов. Показывается, что для обеспечения устойчивости выработок необходимо учитывать длину сейсмической волны (ее первой гармоники), при длине волны меньше размеров выработки нужно применять ее дополнительное крепление даже при больших временах замедления в серии взрывов.

Mineral nucleation is a fundamental process of paramount importance to various fields, including geology, biomineralization, and industrial manufacturing. Recently, studies on the biominerals of calcium carbonate and phosphate have revealed the presence of a dense liquid phase prior to the formation of an amorphous solid phase. However, there is vigorous debate on whether the nucleation of calcium carbonate clusters can be adequately described by the classical nucleation theory (CNT) or if one must turn to the non-classical nucleation theory. Here, we show that liquid-liquid phase separation (LLPS) occurs in a non-aqueous solution where magnesium and calcium carbonates are dissolved in ethanol with excess triethylamine. The nanodroplets can be kinetically trapped by triethylamine. The size and number of the nanodroplets, in the vicinity of critical nuclei, can be adequately described within the framework of CNT. We found that bicarbonate-like species formed by triethylamine, CO2, and ethanol molecules are in constant exchange with sizable carbonate clusters. Our results demonstrate that the concepts of critical nuclei and the energy barrier of nucleation are indeed physically relevant. We argue that nanodroplets comprising highly solvated carbonate clusters are the key entities in the nucleation process, which falls within the realm of CNT.

Free radical-initiated peptide sequencing (FRIPS), a TEMPO-assisted mass spectrometry, has shown potential as a peptide tandem mass spectrometry (MS/MS) tool that can be an alternative to electron-based mass spectrometry and the traditional collision-based methods. However, a couple of instrumentation barriers need to be overcome before this approach can be a practical tool. One of the barriers is the limitation of the FRIPS-based technique to ion trap mass spectrometry or an orbitrap due to the MS3 workflow. To overcome this challenge, the work introduces a recently developed activation within the trapped ion mobility mass spectrometry (TIMS) device that was found to initiate the radical species. More importantly, the generated product ion was mobility separated, which increased the sequence coverage. Overall, coupling the activation within the TIMS cell with the para-TEMPO-Bz-based FRIPS mass spectrometry offers another practical approach that can be utilized for peptide MS/MS analysis.

Solid-state batteries can outperform lithium-ion batteries in energy per unit mass and per unit volume when operating with a Li metal anode. However, metallic Li anodes pose significant manufacturing challenges. Anode-free cells avoid these challenges by plating metallic Li at the anode on the first charge, but subsequent non-uniform cyclic Li stripping and plating encourages unwanted Li dendrite growth, decreased coulombic efficiency, and early cell failure. We report a new spray-printed nanocomposite bilayer of silver/carbon black (Ag/CB) between the anodic current collector and Li6PS5Cl solid electrolyte with Ag concentrated at the current collector. Compared with previous Ag/CB mixtures, the bilayer ensured more uniform Li anode formation and improved cycling performance. Cells with a high-Ni oxide cathode had initial discharge capacity > 190 mAh/g and coulombic efficiency > 98% over 100 cycles. The Li plating uniformity with the structured Ag/CB interlayer was confirmed using secondary-ion mass spectrometry (SIMS) imaging.

Published: October 2024

The emergence of new positions on the issues of gender equality and justice, as they arise in the context of social liberalism and economic reconstruction, serve to ensure equality between men and women. Furthermore, they facilitate the advent of novel approaches to the birth and upbringing of children, and accelerate the transformation of the family institution. The reconciliation of new positions in marriage-family relations and the succession of generations represents an urgent problem that requires sociological analysis. The authors of the article conducted an analysis of the system of sociological theoretical and methodological concepts aimed at explaining the changes in the institution of the family. They also conducted a secondary analysis of the sociological research data (N: 1,200 respondent) on the topic “Kazakhstan Families – 2022”, which was conducted by the NJSC “Kazakhstan Institute of Public Development”. This multifaceted approach enabled the identification and analysis of the changes occurring in marriage and family relations in Kazakhstan. The findings of the analysis indicated that the attitudes and stances of Kazakhstani individuals with regard to the family are characterised by a degree of conservatism. Furthermore, the findings of the study indicate that Kazakhstani individuals place a high value on traditional family values and strive to maintain them. Nevertheless, the most significant value for a contemporary family is care and mutual respect, as well as support, which in the modern era is referred to as an “ecological relationship”. A conceptual analysis of the transformation of the family institution and its interpretation in practice through the results of sociological research has the potential to inform theoretical and methodological decisions in the development of proposals for the regulation of marriage-family relations for submission to state structures and research institutes.
Drill string vibrational analysis and parametric optimization for a portable water well rig development
Authors: Andrew Zivai Borerwe
Published: October 2024

The vibration of a drill string is a key topic of study in drilling and mining engineering. Excessive Drill String (DS) vibrations can lead to early failure of bits due to fatigue, Drill Pipe (DP) fractures, bearing damage, and a decrease in the Rate of Penetration (ROP). This occurs when the drill string rotates at its natural frequency, which is known as resonance. A modal and harmonic vibrational analysis of a drill string up to 60-65 meters long was conducted in a vertical water well through parametric studies. This project investigates the vibration of a drill string under various parameters, including drill string lengths, Weight on Bit (WOB), and drill string rotational speeds. The Rotational Speed (RS) in the drill string induces lateral vibrations and stick-slip in torsional vibrations. Finite element modeling of the drill string was performed using ANSYS Workbench (Mechanical). Modal and harmonic frequencies were determined to obtain the optimal drill string length and rotational speeds, using Campbell diagrams and varying weights on bits. Different weights on the bit were assumed to simulate the drilling environment. One of the modern methods used to simulate dynamic behavior in drilling operations is random vibrational analysis. A random vibrational analysis of the drill string was performed in a vertical water well using ANSYS Workbench 2020. This analysis aimed to identify the frequency response of the drill string, with the probability of deformation for each sigma under random vibration being evaluated. The analysis indicated a higher probability approximately 99.7% of failure along the axis of the supplied PSD acceleration. The response power spectral density (RPSD) was analyzed in the x, y, and z directions, focusing on any point in the bottom hole assembly, primarily the bit. The response PSD results indicated that as the Drill Pipe (DP) increased, resonance spikes rose across all axes, leading to lateral and longitudinal vibrations in the drill string. These findings highlight lateral movement as a primary cause of vibration, offering insights for optimizing drilling parameters.
