The Fluctuation Characteristics and Risk Investigation of China's Gold Future Market
Authors: Wang Shuoran
Published: October 2024

This paper deeply explores the fluctuation characteristics and risks of China's gold futures market. Through the collection of data on macroeconomic factors, stock index interest rates, and energy futures, the paper employs multiple linear regression models and intermediary variable models to quantitatively analyze the impact of these factors on the volatility of gold futures prices. The research finds that there is a significant positive correlation between the gold futures price and the growth of the U.S. GDP and the silver futures price index, while the impact of other macroeconomic indicators such as China's gold reserves and the inflation rate is not significant. Policy support and market regulation play a key role in the healthy development of the market, and the broad participation of market participants and the innovation of financial products have driven the diversification of the market. The intermediary effect analysis shows that the impact of macroeconomic factors on the gold futures price is partially indirect through the intermediary variable of stock index interest rates.
Studies on How New Quality Productivity Drives High-Quality Development of Enterprises
Authors: Wu Chenxi
Published: October 2024

New quality productivity plays an important role at the macro level, such as in society. But can its impact be observed at the micro level, such as within enterprises? This study builds an enterprise-level index for new quality productive forces and empirically examines its impact on high-quality development in organizations using financial information from A-share listed companies from 2012 to 2022. The empirical findings demonstrate that, at the 1% level, new quality productive forces significantly improves high-quality development in businesses. Robustness tests are performed to further support this finding, which involve substituting the dependent variable and removing anomalous years. To lessen the possibility of endogeneity problems resulting from missing factors or inaccurate measurements in explanatory variables, this study employs the instrumental variable method to mitigate these problems, yielding consistent estimation results. In the current societal context, the findings provide recommendations for further enterprise development. Enterprises should actively enhance technological innovation, improve talent development plans, and optimize management structures to ultimately achieve high-quality development.

Designs in Bionic Robots: Compared with Conventional Robots
Authors: Zhang Mengyao
Published: October 2024

With the advancement in relative technology, robotics is gaining an increasing amount of attention among engineers and researchers as it is a current focus on enabling peoples lives to become more convenient. However, there is another type of robot designed very differently from functional robots like delivery robots and quadrotors that most people are familiar with, bionic robots. This is a kind of robots that gets design inspiration from real animals in nature, from the design of structure to altitudes and mechanisms of motion. How bionic robots are designed, and how the conceptional difference of bionic robots with other robots is reflected on their physical designs are the focuses of this paper. In this paper, four basic types of bionic robots are introduced and 17 existing designs of bio-inspired vehicles are included. 10 bionic aerial vehicles in 3 smaller classifications are compared to 3 conventional aerial vehicles in order to figure out differences in 3 aspects (structure design, sensors, and control method). The results show that bionic robots usually have more degrees of freedom in order to mimic animals attitudes, and are lighter in weight. Typically, bio-inspired aerial vehicles employ different wing systems compared with conventional ones. Additionally, while conventional vehicles favour PID more because of its ease of construction, bionic robots use machine learning techniques. Both types of robots use the same sensors, which is necessary for them to detect their environment. However, their control methods differ due to different purposes.

The fight against weeds in crops and plantings of agricultural crops, both annual and perennial, has been and remains one of the most important scientific problems of agricultural production. The relevance of the research lies in a comprehensive study of the effectiveness of the use of modern promising herbicides in hazelnut orchards, in order to optimize measures to combat weeds. The research results made it possible to develop a system for maintaining soil in a walnut orchard using modern herbicides. To solve the problem, it is necessary to conduct geobotanical studies of the weed component in the walnut orchard, to determine the magnitude of the negative impact of various doses of herbicides in the inter-rows and rows of hazel. The authors first obtained data on the use of herbicides on gray forest soils, with alluvial deposits, skeletonized and rocky in the Iraf region of the Republic of North Ossetia, which are characterized by a humus content of 6-8%, phosphorus up to 200 mg/kg, potassium up to 42 mg/kg and acidic reaction of the soil solution (pH 5.1). The object of the study was weeds in perennial walnut plantations, among them difficult-to-eradicate root shoot thistles (Cirsium arvense), (Sonchus arvensis), creeping bitterweed (Acroptilon repens); rhizome creeping wheatgrass (Agropirum repens) and others. It was established that the use of herbicides Lontrel -300, VR (3 l/ha), Hurricane Forte, VR (2 l/ha), Basta, VR (5 l/ha), Sprut Extra VR (3 l/ha) reduced the number of weeds ranging from 84.8% to 89.9%. Recommendations are given on the timing of application of the most promising herbicides in perennial hazelnut plantations. The predominant effectiveness among the herbicides studied was shown by Octopus Extra VR.

In a long-term stationary field experiment that was established in 1971 on leached chernozem underlain by pebbles under conditions of field crop rotation the effect of systematic application of fertilizers for hybrid corn on plant growth processes was studied. It was found that the fertilized variants increased relative to the control: the growth of plants in height, the increase in leaf surface area, the accumulation of raw and dry biomass, increased photosynthetic potential. From the fertilized options, the calculated option N310P324K139 stood out for the better for the planned yield of 8.0 t/ha. In this variant at the end of the growing season the average height of the plant was 256 cm versus 247 cm in the control; the leaf surface area was 60056 versus 49392 m2/ha in the control; the photosynthetic potential was 3.08 million m2/ha.day versus 2.53 at the control; the amount of dry biomass is 22.5 versus 15.0 t/ha at the control. According to all indicators the double dose of N140P80K180 was in second place: respectively accordingly 255 cm, 56,808 m2/ha, 2.87 million m2/ha.day, 20.4 t/ha. Of the equivalent options a double dose of NPK had some advantage over manure+NPK (trend).

O estabelecimento comercial, enquanto objecto de negócios jurídicos, em Angola
Authors: Sukuakueche Simão Antunes
Published: October 2024

This research studies the commercial establishment in Angola, as a unitary object of legal business, that is, leasing and transfer and its respective legal framework in Angolan law. The scope of which is to characterize the commercial establishment in a common sense, identify the legal transactions inherent to it and determine its legal regime in Angola, considering that its legal nature is a vexing question in domestic and international legal doctrine. In accordance with the proposed theme, the issues raised and the recommended objectives, this research is methodologically bibliographical, documentary and survey-based. Commercial establishments in Angola are subject to leasing and transfer, whose legal framework is still outdated, limited and ineffective given the current legal, economic, business and social context of the country and the world. Hence the reason for the existence of some dubious and controversial legal-doctrinal issues and, consequently, some legal-contractual problems, in cases of leasing and transfer of commercial establishments in Angola. For example, issues and problems relating to the transmission of credits and, above all, debts resulting from the commercial activity of an entrepreneur or business company through a commercial establishment that has already been leased or transferred. Therefore, this research proposes some essential theoretical-practical guidelines for a better approach and regulation of leasing and transfer in Angola. Therefore, there is a need to update or reform the legal framework on this matter in Angola to solve the problematic of this research.

Chronopotentiometric Stripping Analysis of Proteins and Their Interactions
Authors: Staroňová Tatiana , Ostatná Veronika
Published: October 2024

Chronopotentiometric constant current stripping analysis (CPS) is a highly sensitive method for protein analysis that does not require modification or labeling. During the CPS analysis, proteins yield the so-called peak H, resulting from the catalytic hydrogen evolution reaction. This peak is sensitive to both local and global changes in protein structure, allowing the study of individual proteins, as well as their complexes. CPS analysis has been utilized in studying biomedically important proteins involved in neurodegenerative diseases and cancer. In this article, we describe the development of CPS protein analysis and its progress over the past decade. We also demonstrate the versatility of the method and its potential applications.

Published: October 2024

Objetivo: Estimar a prevalência de sintomas depressivos e risco familiar em Unidade de Saúde (US) do sul do Brasil, identificando fatores associados aos desfechos de interesse. Metodologia: Estudo transversal realizado com adultos em acompanhamento na US Conceição em Porto Alegre, Rio Grande do Sul, em 2020. A coleta de dados envolveu a aplicação de questionário sociodemográfico, aferição de medidas antropométricas, avaliação de sintomas depressivos pelo Inventário de Depressão de Beck (BDI) e a Escala de Risco Familiar (ERF). A comparação das médias dos escores do BDI e ERF em relação às demais variáveis foi realizada pelo teste t de Student ou ANOVA e a Regressão de Poisson foi utilizada para análises multivariadas. Resultados: Foram incluídos 98 participantes com média (± desvio-padrão) de idade de 42,8 ± 11,9 anos, predominantemente do sexo feminino (83,7%) e de raça/cor branca (84,7%). A prevalência de sintomas depressivos clinicamente relevantes na amostra foi de 55,1% e 31,6% dos participantes apresentaram algum grau de risco familiar. Participantes com histórico familiar de depressão apresentaram maior média (± desvio-padrão) no escore BDI em comparação ao grupo sem histórico familiar de depressão (18,5 ± 9,1 vs 9,2 ± 8,4; p ≤ 0,001). Na análise multivariada, a prevalência de depressão foi 1,55 vezes maior em indivíduos com histórico familiar de depressão em relação aos participantes sem histórico familiar de depressão (IC95%, 1,27 - 1,91; p ≤ 0,001). Não houve diferença estatisticamente significativa entre as médias da ERF das variáveis sociodemográficas avaliadas e entre as médias das medidas antropométricas dos grupos com e sem sintomas depressivos. Conclusão: A alta prevalência de sintomas depressivos na população estudada e sua forte associação com histórico familiar sugerem que a investigação rotineira do histórico familiar possa ser uma medida simples e eficiente para a identificação de indivíduos com risco de depressão no contexto da Atenção Primária à Saúde.

Published: October 2024

The fashion sector, which contributes approximately 10% to global carbon emissions, exerts a considerable influence on the environment. The rapid pace of fast fashion has intensified both waste generation and resource utilization, thereby rendering sustainable practices an essential requirement. This study examines sustainable methodologies within the fashion industry, with particular emphasis on the implementation of the Reduce, Reuse, and Recycle (RRR) framework. The article explores how global and local brands in Delhi incorporate such strategies into their operations and gauges consumer awareness and behavior towards sustainable fashion. Studies indicate that barriers faced by brands while trying to achieve sustainability include the high price tag of sustainable materials, minimal recycling facilities, and the price sensitivity of the consumer. Hypothesis testing was used to examine whether the consumer behavior was significant on their purchasing decisions and sustainability. The results reflected that, while there is indeed a growth in awareness, consumers' intentions and actual purchasing behaviors seem to be quite divergent concerning the acceptance of sustainable fashion. Furthermore, the paper makes workable recommendations to make the fashion industry more sustainable by focusing on policy measures, innovations in brands, and education for the consumer. Key Words: sustainable fashion, reduce reuse recycle, consumer behavior, competitive advantage, supply chain sustainability

Known as hypertension, or high blood pressure, is a non-communicable disease (NCD). Preliminary study data from Dr. Kariadi Semarang Central Public Hospital indicated 561 patients with hypertension over the last three years (2021–2023). Hypertension symptoms often resemble those of other diseases and can vary among individuals, including fatigue, palpitations, increased blood pressure, nosebleeds, headaches, and nocturia, which can disrupt sleep quality. One of the non-pharmacological effort to prevent hypertension is slow-stroke back massage, This study aimed to determine the effect of slow-stroke back massage on blood pressure and sleep quality in hypertension sufferers. The research design employed a quasi-experimental method with a one-group pretest-posttest approach, involving 42 respondents selected through purposive sampling. The results demonstrated that slow-stroke back massage effectively reduced systolic blood pressure (p-value = 0.00) and improved sleep quality scores (p-value = 0.00). Slow-stroke back massage can enhance relaxation and increase parasympathetic nerve activity, thereby reducing the heart's workload. This study recommends that nurses apply slow-stroke back massage therapy in hospitals to help control blood pressure and improve the sleep quality of hypertension sufferers.

To improve the cutting performance when cutting hard alloys and achieve reasonable optimization of micro-texture parameters, this paper proposes a sinusoidal micro-textured tool, with four parameters set as micro-textured spacing, period, width, and amplitude. Establish three-dimensional models of non-micro-textured and micro-textured milling tools and simulate the milling process using finite element simulation. Study the effects of milling force and milling temperature on tool performance. Prepare micro-textured milling tools for orthogonal experiments, analyse the effects of milling force and the surface roughness of a titanium alloy workpiece, and study the impact of different micro-textured parameters on milling tool performance. Obtain the parameters that have the greatest impact on milling tool performance, and then use genetic algorithm to optimize three sets of parameter combinations. Use the optimized parameters to prepare milling tools for comparative experiments, and then determine the optimal parameter combination. The research results indicate that micro-textured tools can effectively improve the milling performance of the tool, and the spacing between sinusoidal micro-textures has the greatest effect on improving the milling performance of the tool. When the period of sinusoidal micro-texture is 2.87 and the amplitude is 25.13 μm, width is 79.89 μm, and spacing is 134.54 μm, the milling performance of the tool is optimal.

Authors: Jasim Abbas Ibtihal
Published: October 2024

In its active form, resentment can be a forceful response to acts that have created unjustified suffering. In relation to Al-Zahraa’s sermon, she feels injustice when her earth and right has been taken after her father death. As such, she goes to the mosque where Abu Baker and others found and delivers her speech. Stylistically, Al-Zahraa uses certain devices or deviations as a way to deliver her message effectively to the audience. Consequently, the study tries to find answers to the following questions: (1) how is resentment manifested in Al-Zahraa’s sermon? (2) what are the stylistic devices that are utilized in Al-Zahraa’s sermon? (3) Does Al-Zahraa succeed in expressing her resentment effectively? And (4) To who her resentment is directed? Due to these problems, the following aims are set: (1) showing out how resentment is manifested in Al-Zahraa’s sermon, (2) identifying the stylistic devices that are used in Al-Zahraa’s sermon, (3) clarifying whether Al-Zahraa succeeds in expressing her resentment effectively or not, and (4) Identifying the addressee that Al-Zahraa wants to deliver her resentment to.  In the light of these aims, the paper hypothesizes the following: (1) resentment is manifested through using certain strategies and devices, (2) there are some stylistic devices that are heavily used in Al-Zahraa’s sermon, and (3) Al-Zahraa succeeds in expressing her resentment effectively, and (4) All of Al-Zahraa resentment speech is directed to an individual. After presenting a background knowledge about resentment and some stylistic devices with analysing some extracts taken from Al-Zahraa’s sermon, some conclusions are reached.

Published: October 2024

The current research study is an attempt to trace the religious impact on selected poems written during the invasion of some Iraqi provinces by ISIS from a psychological perspective and literary explication, disability theory. The religious authority is a very essential cornerstone in the Muslim worlds in general and in Iraq in particular as there are many denomination heads and many edicts. The selected poems, whose main focal theme is an invasion-and-liberation stratum of the Iraqi lands, are collected from Arabic literature and English one to apply a sense of diversity and universality to the article. How the edicts fall into the orbit of the laypeople mentality as reflected in verse and how the nonMuslims portray the edicts on the one hand, how the poets broach the edicts, what tone they employ, what technique they implant and what messages they endeavour to convey on the other hand.
     In doing so, the study gives much shrifts to the procedures to cull a tint of objectivity in the welter of emotionality and simpatico factors, that is, there are three chapters, the first tackles Hawza edicts and the sapience of the modest-house man, the second does the canonical poets as compared to other ones in the light of the missions beyond the texts and the third does the challenges between despair absorber and cataclysm amplifier in the selected poems. Ultimately, the conclusion fathoms the major scope of the article as much as it trucks the echo of the edict in the samples.

يمكننا معرفة وتقييم الخطاب الاسلامي في ضوء الرؤية المعتدلة. فالخطاب الذي يحمل منهج القران طريقاً للحياة والخلق الرفيع الذي يتحلى به النبي الاكرم واله الاطهار ومن سار على هديهم يمكن ان يوصف بإنه خطاب إسلامي ويستحق هذا الوصف فالقران يقدم الوسطية على ان الاسلام وخطابه الحقيقي يعّد معياراً تقاس عليه القيم الاخرى، ليس من باب الاكراه والجبر، وإنما من باب الاقناع والتواصل مع الشعوب الاخرى، والوسطية قد تعني البحث عن الحقيقة، وعندها ستكون منهجاً رائداً في الوصول الى حقيقة الخطاب الذي يتبناها. وقد دأبت مجلة العميد منذ ولادتها على ان يكون الخطاب الاسلامي الذي تتبناه هو من هذا النوع الوسطي، وكذا لم تهمل مخاطبة المتلقي الذي يحمل ثقافة الزمن الراهن وحداثته فهي أسست لهذا النوع من الخطاب في احد ملفاتها المسمى (الحداثة المتوازنة) الذي يهدف الى اكتشاف مقولات تحليلية وسطية تميز الخطاب الإسلامي عن الخطاب الحداثي الغربي، اما التواصل الذي نريده هنا هو يقترب من المعنى الاصطلاحي لهذه المفردة فيمكننا ادخال كل عمليات الاتصال اللغوية والعملية والسلوك الفردي او الجماعي الذي يمثل أسس العلاقات المتبنية لإيصال الرسالة، وهو هنا يقترب من معنى  الخطاب، بل قد يكون صفة من صفاته الثابتة والدائمة، وهو يشمل عملية التلقي والاثارة والسيرة والمنهج والحوار والتداول، وهذه كلها مقاربات يمكن اعتمادها في عملية البحث الذي بين يدينا.

Published: October 2024

This study presents a quantitative evaluation of the acid-base dissociation mechanisms in the dyes Methylorange and Methylred, which are commonly used as pH indicators in various chemical and biological applications. Using spectrophotometric techniques, the dissociation constants (pKa) of these dyes were determined across a range of pH levels. The research involved systematic measurements of absorbance changes in response to pH variations, allowing for precise calculation of the dissociation equilibria. Methylorange, known for its sharp color transition between red and yellow, and Methylred, which transitions from red to yellow, were analyzed to compare their acid-base behavior and the impact of structural differences on their dissociation mechanisms. The study also examined the influence of ionic strength and solvent effects on the dissociation constants to better understand the environmental factors affecting the performance of these indicators. The results indicate distinct dissociation profiles for Methylorange and Methylred, with Methylorange exhibiting a more pronounced pH-dependent color change compared to Methylred. The findings provide valuable insights into the practical applications of these dyes in pH measurement and their behavior under different conditions. This quantitative assessment not only enhances the understanding of the acid-base chemistry of these indicators but also informs their optimal use in various scientific and industrial contexts.
