В данной статье приводится обзор работ, посвященных влиянию гексанитрогексаазаизовюрцитана на живые организмы. Рассматриваемый ареал обитания включает в себя: водоемы, грунтовые воды, почвы на разных уровнях. Производство, использование и утилизация веществ приводит к серьезному загрязнению окружающей среды. Широко применяемые взрывчатые вещества, например циклические нитрамины – гексоген и октоген, являются токсичными для различных наземных и водных экосистем, а представление химических и аналитических данных об их механизмах транспорта и трансформации в почве является предметом широкого изучения. Из-за высокой энергоемкости каркасные полинитраамины кажутся более привлекательными, чем используемые в настоящее время гексоген и октоген. Поэтому экологические исследования 2,4,6,8,10,12-гексанитро-2,4,6,8,10,12-гексаазаизовюрцитана (CL-20), проводимые во всем мире имеют большую практическую значимость. Исследования показали, что агробактерии, псевдомонады и кишечная палочка способны к биотрансформации CL-20. На люцерну, раерграсс, морские бактерии и пресноводные зеленые водросли влияния вещества и его биотрансформантов замечено не было. Конечные точки, такие как выживание, рост и воспроизводство биологических видов являются экологически и токсикологически релевантными, но также необходимо знать, что механизм действия воздействующ

This article provides an overview of the work on the effects of hexanitrohexaazaisowurtzitane on living organisms. Considered habitat includes: water, groundwater, soil at different levels. The production, use and disposal of substances leads to serious environmental pollution. Widely used explosives, such as cyclic nitramines - hexogen and octogen, are toxic to various terrestrial and aquatic ecosystems, and the presentation of chemical and analytical data about their transport and transformation mechanisms in soil is a subject of extensive study. Because of their high energy intensity, frame polynitraamines seem more attractive than the currently used hexogen and octogen. Therefore, environmental studies 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20) carried out throughout the world are of great practical importance. Studies have shown that agrobacteria, pseudomonads and E. coli are capable of CL-20 biotransformation. The effects of the substance and its biotransformers were not observed on medicago, arrhenatherum, sea bacteria and limnetic green algae. Endpoints such as the survival, growth and reproduction of biological species are ecologically and toxicologically relevant, but it is also necessary to know that the mechanism of action of the affecting substance. Studies have shown that CL-20 can penetrate the skin and accumulate in the body of earthworm, is also a reproductive toxicant with a lethal effect.

В статье представлены результаты теоретических исследований импульсного ультразвукового воздействия на пороговую интенсивность, приводящую к возникновению кавитации. Предложена физико-математическая модель, которая описывает процесс возникновения кавитационных пузырьков при воздействии импульсным ультразвуком (высокочастотными синусоидальными колебаниями, модулированными по амплитуде прямоугольными импульсами), позволяет выявить динамику прямой диффузии газа, растворённого в жидкости, в полость кавитационного пузырька и, в конечном итоге, рассчитать пороговые интенсивности, при которых кавитационный пузырёк начинает схлопываться, от длительности ультразвукового импульса и вязкости жидкости.

The article presents the results of theoretical studies of pulsed ultrasonic exposure to a threshold intensity leading to cavitation. A physical and mathematical model is proposed that describes the process of cavitation bubble formation under the influence of pulsed ultrasound (high-frequency sinusoidal oscillations modulated by the amplitude of rectangular pulses), which allows to reveal the dynamics of direct diffusion of a gas dissolved in a liquid into the cavity of a cavitation bubble and, in ultimately, calculate the threshold intensities at which the cavitation bubble begins to collapse, from the duration of the ultrasonic pulse and the viscosity of the liquid.

Published: October 2024

В бесплатформенных инерциальных навигационных системах (БИНС) переход от связанной с подвижным объектом системы координат к инерциальной осуществляется с использованием параметров ориентации. Для малогабаритных автономных подвижных объектов (АПО) в качестве последних целесообразно использовать кинематические параметры Родрига-Гамильтона. Вычисление этих кинематических параметров и параметров навигации АПО заключается в решении систем дифференциальных уравнений, процесс интегрирования которых может быть эффективно реализован в нейросетевом базисе. Как следствие, вся система управления движением АПО, включая и решение задачи распознавания цели поражения, может быть реализована с использованием нейросетевых принципов организации вычислительного процесса.

In free-to-air inertial navigation systems, the transition from a mobile object-related coordinate system to an inertial system is made using orientation parameters. For small autonomous mobile objects (AMO) as the latter it is advisable to use the kinematic parameters of Rodrigue-Hamilton. Calculating these kinematic parameters and AMO navigation parameters is to solve differential equation systems whose integration process can be effectively implemented in the neural network base. As a result, the entire AMO motion control system, including the problem of recognizing the purpose of the lesion, can be implemented using the neural network principles of the organization of the computational process.

معاني النصّر في القرآن الكريم وأسبابه
Authors: عودة إبراهيم يوسف حماد
Published: October 2024

جاء النصر في القرآن الكريم بألفاظ ومعاني عديدة تحمل معنى النجاح والفوز، وينقسم لنوعين نصر في الحياة الدنيا ونصر في الحياة الآخرة، أما أسباب النصر فهي نوعان أيضاً أما مادي يعتمد على قوانين الكون والعلم والأخذ بالأسباب، إذا اتخذها الإنسان انتصر وتقدم، وجانب معنوي لتعبئة الإنسان روحياً ليكون مهيئا على النصر والصبر وعدم الخوف. أما ترك المؤمنين للعمل واعتمادهم على مجيء النصر من الله فقط دون أخذ بالأسباب فهو خلل في فهم النص القرآني، فالتدخل الإلهي لا يعني إرسال الملائكة للقتال عوضا عن المسلمين، بل على المسلمين الإعداد الكامل والقتال. ويهدف هذا البحث إلى كشف معاني النصر والألفاظ المشابهة لها، كما يهدف إلى إثبات أن للنصر في القران الكريم أسباب وقوانين يجب العمل بها وان الله ينصر عباده إذا عملوا على النصر لا بالتواكل. استخدم الباحث أسلوب المنهج الوصفي التحليلي حيث تم التركيز على وصف النصر ومعانيه وذكر أسباب النصر وطرقها، وخرجت الدراسة بنتائج أهمها أن النصر بكل معانيه يعني الفوز في نهاية الأمر أو الشيء، ولذلك فأسبابه دنيوية وقد خلق الله للإنسان العقل ليستخدمه ويتقدم به وينتصر.

Light triggers numerous fundamental biological processes in living organisms, by promoting (multi)chromophoric biomolecular systems to an excited state, which activates their function. The ability of these photoactive systems to absorb and use solar energy is often regulated by their microenvironment, which modulates their structural and energetic landscape and, thus, their functionality. Various stimuli-responsive photoactive materials are designed based on this principle. Understanding how photoactive molecular systems respond to light and environmental changes requires tracking changes at both the electronically excited- and ground-state levels, with ultrafast resolution across a broad range of timescales. Indeed, while light-induced excited-state dynamics involve processes as rapid as a few femtoseconds, the structural and electrostatic responses to microenvironmental changes may occur at timescales orders of magnitude slower, up to the millisecond and beyond. We demonstrate that this investigation can now be enabled by a novel and universal three-pulse ultrafast spectroscopy method that: (i) induces controlled, local changes in the microenvironment of a solution, specifically of pH, and (ii) probes the rapid spectroscopic response of photoactive molecules in both the ground and excited states, from femtoseconds to milliseconds. Controlling changes in the microenvironment and – simultaneously – bridging the ultrafast timescales of excited-state dynamics with the slower timescales of environmental and conformational changes is key to advancing our understanding of how living organisms and artificial materials regulate the interplay between light, environment, and structure in light-induced molecular processes.
Believing in an Otherwise

This paper will propose that Gloria Anzaldúa’s “spiritual activism,” as a praxis wrought through the confluence of the spiritual and the political, could also be a model for embarking upon the study of religion differently. Walter Mignolo emphasizes that to understand what it means to decolonize requires specificity, through “looking at other W questions: Who is doing it, where, why, and how?” I shall suggest that spiritual activism as a decolonial framework demands that scholars of religion ask themselves, in turn, what they believe.

Among urban school girls 3294 1.02 were obese while among rural school girls 1195 0.5 was obese. About 68454 14.9 urban boys 50248 20 rural boys 65294 22 urban girls and 70195 36 rural girls showed healthy weight BMI.Conclusion Unlike the common concern about obesity in Indian school children this study indicates that underweight is more prevalent especially among urban school children boys and girls compared to rural school children.
Galacto-oligosaccharides as functional foods and their properties
Authors: Abdaltef M.J. , Al-Shawi S.G. , Al-Temimi W.K.
Published: September 2024

Galacto-oligosaccharides (GOS) are classified as prebiotics due to their indigestible
nature. GOS are regarded as resistant to salivary digestion and are not utilized by the
mouth. Thus, they can be utilized as substitutes for low-cariogenic sugar. The structure of
GOS mixtures is determined by the differentiation between the transferase reaction and
hydrolysis. Transgalactosylation can be achieved intramolecularly when the glycosidic
bond in lactose cleaves and reassembles itself on another glucose molecule. Microbes can
be used as a source for the β-galactosidase enzyme or as agents to produce GOS units.
Commercial β-galactosidase enzymes likewise do have a great potential for their use in
GOS synthesis. These transgalactosyl reactions could find useful applications in dairy.
Since 70% of the world's population cannot tolerate lactose, lactose utilization could only
be enhanced through hydrolysis into its components, the monomer sugars of D-glucose
and D-galactose. GOS can be produced industrially using whey or lactose as the substrate.
Trisaccharide (β1-4 or β1-6 galactosyllactose) are generally the major products of this
process. In comparison with lactose and other saccharide molecules, GOS has been shown
to have low carcinogenicity, low calorific value, and low sweetness. This review focuses
on GOS production, and the physicochemical characteristics, physiological effects, and
applications of these prebiotics are summarized.

Authors: Shi Buchao , Li Changhong , Li Dong , Li Hui
Published: October 2024

Objective: This study aimed to investigate the role of Hedysarum polybotrys polysaccharide (HPS) in ameliorating neural tissue fibrosis in diabetic peripheral neuropathy (DPN) mice. Methods: Fifty DPN mice were selected and randomly divided into five groups (n = 10), which were the model group, positive control group (receiving only 4 mg/(kg-d) of α-lipoic acid), high-dose HPS group (200 mg/(kg-d) of HPS was given per day), medium-dose HPS group (100 mg/(kg-d) of HPS was given per day), and low-dose HPS group (50 mg/(kg-d) of HPS given daily). In addition, non-diabetic C57BL/6 wild-type mice were selected as the normal group (n = 10). The expression levels of Keap1 and Nrf2 proteins and their mRNAs in the sciatic nerve tissues of mice in each group were analyzed by Western blot technique and real-time fluorescence quantitative PCR. Results: Compared with the normal group, the expression of Keap1 protein and mRNA was increased, while the expression of Nrf2 protein and mRNA was decreased in the sciatic nerve of mice in the model group (P < 0.05). Compared with the model group, Keap1 protein and mRNA expression decreased, while Nrf2 protein and mRNA expression increased in the control and high and medium dose HPS groups of mice (P < 0.05). Conclusion: HPS may inhibit fibrosis of neural tissue and ameliorate nerve injury in DPN mice by regulating the Keap1/Nrf2 signaling pathway. This effect was associated with enhanced antioxidant capacity, promotion of Nrf2 activation, and increased antioxidant gene expression by HPS. Therefore, HPS has a potential therapeutic value to ameliorate DPN-associated nerve injury.

The capability to detect anti-aquaporin 4 antibodies is pivotal for improving the efficiency of screening and diagnosing neuromyelitis optica, thereby possessing considerable potential for clinical application.
Advancements in the Study of Clinical Features and Molecular Functions in Heterogeneous TAF1-associated Clinical Phenotypes
Authors: Xiao Hui , Peng Jing , Mao Leilei
Published: October 2024

Purpose of review: TATA-binding protein (TBP)-associated factor 1 (TAF1) encodes the largest component of the transcription factor IID (TFIID) complex, which binds to core promoters and serves as a scaffold for assembly of the RNA polymerase II transcription complex. Variants in TAF1 are associated with X-linked dystonia-parkinsonism (XDP) and X-linked syndromic mental retardation-33 (MRXS33). This review provides a concise summary of the genetic and clinicopathological features of TAF1 variants related to phenotype. Recent findings: XDP is an adult-onset X-linked progressive neurodegenerative disorder presenting dystonia and parkinsonism and caused by a SINE-VNTR-Alu (SVA)-type retrotransposon within TAF1. TAF1/MRXS33 intellectual disability syndrome is characterized by global developmental delay, intellectual disability, facial dysmorphia, generalized hypotonia, and neurological abnormalities due to the missense variants in TAF1. Various symptoms of TAF1 missense mutations may be related to mutations in different functional regions of the protein. The clinical manifestations of XDP and MRXS33, both caused by variants of TAF1, present prominent heterogeneity, which could be influenced by whether the TAF1 mutation is located in the coding region, the time when TAF1 expression decreases, and the effect on downstream gene expression. Summary: TAF1 is linked to many different phenotypes because of its variable regulation of coding and noncoding elements, which makes its mechanistic roles in disease challenging to interpret. However, it is important to note that strategies to correct TAF1 splicing could provide therapeutic benefits in different diseases.

The Path of Constructing Cultural Confidence under the View of Materialistic History
Authors: Zhang Zhikun
Published: October 2024

Cultural self-confidence is the most basic, deepest, and lasting force in the development of a country and a nation. Cultivating and constructing cultural self-confidence requires scientific theoretical guidance. As a theory revealing the general laws of human social development, the Marxist materialist concept of history is a great “cognitive tool” for analyzing and solving social problems, which not only provides a profound theoretical and philosophical foundation for firming cultural self-confidence but also provides a scientific methodological approach for fostering cultural self-confidence. The General Secretary has mentioned cultural self-confidence many times, pointing out that culture is a kind of soft power of the country and explaining the importance of culture. Cultural self-confidence from the perspective of historical materialism is embodied both at the level of principles and at the level of methodology. The basic principles of the materialist concept of history are the theoretical guidance of cultural self-confidence. At the same time, cultural self-confidence under the guidance of the materialist concept of history is also of great significance to the construction of a strong modern socialist country.

The Employment Outlook of Urban Youth under Consumption Downgrading
Authors: Gao Liying
Published: October 2024

This paper uses participant observation and semi-structured interviews to examine the presentation of urban youth’s employment outlook in the context of consumer downgrading, and explores the shaping factors behind it to provide rational explanations. Through the classification and analysis of employment attitudes and expectations, it is found that the employment expectations of urban youths tend to be de-employerization and career digitization, lifelong learning and compound talents, embracing new industries and engaging in new occupations as amphibious youths and slash-and-burn youths, and presenting attitudes of pursuing the fulfillment of self-worth, and attaching equal importance to responsibilities and ideals. The emergence of employment attitudes and expectations is related to the acceleration of modernity and pressurized survival, as well as the awakening of self-consciousness among urban youth. In this regard, society at large should respect and adjust to their new employment mentality and expectations, so that they can firmly hold on to their ideals, which is also of great significance in promoting the in-depth optimization of the human resources structure.
A Study of Group Work Intervention on Children’s Concentration in Lower Grades: A Case Study of Children’s Concentration Enhancement Group in Elementary Schools
Authors: Li Jiawei
Published: October 2024

According to the survey on the concentration level of children in the lower grades, the results show that most of the children have concentration deficits. Concentration ability plays a crucial role in children’s intellectual development. With the continuous development of science and technology, different types of electronic products are emerging, which will undoubtedly create a great temptation for children. This hinders the development of children’s ability to concentrate, which not only affects the development of their own ability but also poses a threat to their future development. Therefore, it becomes an essential course to improve children’s ability to concentrate. This paper adopts research methods such as participant observation method and interview method, based on social learning theory, social support theory, and other related theories, through the J City social work service agency selected six children in the lower grades who are not focused and voluntarily participate in this activity into group activities, analyzed the practical effect of group work intervention in the lower grades concentration and problems from the practical point of view. On this basis, corresponding countermeasures are proposed to improve the quality of group intervention services. This paper found that the practical effects of group work intervention on children’s concentration in the lower grades include: improving children’s concentration, promoting children’s self-knowledge, and enhancing children’s self-confidence. Problems include insufficient parental participation and insufficient peer group social interaction. The following countermeasures are proposed: building a platform for peer interaction to improve children’s concentration; constructing a social support network for children with the participation of multiple parties; social workers clarifying their own role positioning and flexibly switching their roles; and enhancing their professional competence and strengthening their practical work skills.
The Change in Marriage and Childbearing Culture in China and Its Influence on the Fertility Rate
Authors: Wu Yumo
Published: October 2024

With the rapid development of modern society, China’s marriage and childbearing culture has also undergone great changes, but there is little discussion on the influence of the change of marriage and childbearing culture on the fertility rate. Through research, it is found that in China’s traditional marriage and childbearing culture, people’s marriage and childbearing behavior is greatly influenced by the family, so “early marriage and early childbearing”, “multiple births and childbearing”, and “preference for male children” are significant features in the traditional marriage and childbearing culture. After entering modern society, China has gradually formed a new modern marriage and childbearing culture, and materialism has gradually replaced familism, in which materialism is essentially a low fertility culture. Therefore, under the influence of a series of intermediary factors, this new marriage and childbearing culture has kept the fertility rate at a low level.

Authors: Zhu Rongxian , Chen Ting , Luo Shanshan , Yang Kaiyuan
Published: October 2024

The potential applications of superhydrophobicity for self-cleaning, microfluidic systems, and so on, inspired by the “lotus leaf effect”, have recently attracted great attention from academia and industry. To date, however, neither experimental nor theoretical studies have reached the scalable application of superhydrophobic surfaces, and no simple methods have been developed to produce durable superhydrophobic surfaces. In this project, conical, cylindrical, and cube microstructures with different shapes and dimensions were prepared by 3D printing. Among these structures, the conical microstructures without further modification exhibited the best hydrophobic performance with a contact angle of 120°. However, the hydrophobic performance of the cube microstructures was significantly improved with the addition of an FAS coating to the surface, reaching 131°. This indicates that, with the help of the coating, the 3D printed materials with special features can be transformed into hydrophobic surfaces. The outcome of this project will be useful in promoting the efficient and low-cost preparation of superhydrophobic functional surfaces and their engineering applications.
