Research on integration technology of architectural CAD and budget estimate

It is particularly important to integrate architectural CAD and budget integration technology in the field of modern construction project management. Faced with the increasing complexity of construction projects, the method of separating design and budget in the past is no longer suitable for the standards of efficient management. Starting from the basic concepts and core technologies of architectural CAD, this article studies the difficulties in data transmission and conversion, as well as the strong demand for integration technology throughout the entire building lifecycle. Analyzing the implementation methods of integrating architectural CAD and budget technology, including data docking, the application of BIM technology, and collaborative work modes, this article explains the positive role of this integration in enhancing the unity of design and budget, improving change response speed, and reducing costs, providing reference for the information development of the construction industry.

An Assessment of Rural Midwestern Schoolteachers' Nutrition Literacy and MyPlate Knowledge: Implications for Current Practice and Policy.

Background. Rural schoolchildren outpace their urban counterparts in obesity and diet-related chronic disease rates. Educating students on nutrition basics may help reduce these health burdens in this focus population. Rural schoolteachers are ideally positioned to teach students about nutrition; however, to teach nutrition, one must first understand basic nutrition concepts. The nutrition literacy and knowledge of rural schoolteachers, as well as strategies to and barriers for integrating nutrition into rural classrooms, are understudied. Examining these topics may provide a deeper understanding of nutrition education in rural schools. Methods. Data were collected via an online survey of K-12 teachers (n = 153) from seven Midwestern rural school districts. This survey collected data on nutrition literacy, nutrition knowledge, and preferred methods for implementing nutrition education into current curricula. Descriptive statistics were reported; associations between nutrition literacy and knowledge were examined. Results. Nutrition literacy levels were borderline low (mean score 45.7 out of 64). Nutrition knowledge and literacy were associated (p < .001). Most teachers (n = 108, 70%) were/may be willing to change lessons to incorporate nutrition information, with hands-on and group activities being preferred strategies. Barriers to including nutrition information into curricula included lack of time, knowledge, and resources. Most teachers reported little support from administration for promoting nutrition in the classroom. Discussion. Implementing nutrition education into teachers' continuing education requirements may provide a means of improving teacher nutrition literacy and knowledge. Support from both state-level and local administration could benefit both nutrition knowledge acquisition by schoolteachers and implementation of nutrition education throughout the curriculum.

Fundamentals and Challenges of Ligand Modification in Heterogeneous Electrocatalysis

AbstractThe development of efficient catalytic materials in the energy field could promote the structural transformation from traditional fossil fuels to sustainable energy. In heterogeneous catalytic reactions, ligand modification is an effective way to regulate both electronic and steric structures of catalytic sites, thus paving a prospective avenue to design the interfacial structures of heterogeneous catalysts for energy conversion. Although great achievements have been obtained for the study and applications of heterogeneous ligand‐modified catalysts, the systematical refinements of ligand modification strategies are still lacking. Here, we reviewed the ligand modification strategy from both the mechanistic and applicable scenarios by focusing on heterogeneous electrocatalysis. We elucidated the ligand‐modified catalysts in detail from the perspectives of basic concepts, preparation, regulation of physicochemical properties of catalytic sites, and applications in different electrocatalysis. Notably, we bridged the electrocatalytic performance with the electronic/steric effects induced by ligand modification to gain intrinsic structure‐performance relations. We also discussed the challenges and future perspectives of ligand modification strategies in heterogeneous catalysis.

Sensemaking of wave–particle duality in a scientific outreach minicourse: a study based in self-regulation

Abstract On the Internet, Quantum Mechanics is an area of physics that is shrouded in misinterpretations. In this scenario, scientific outreach may serve as an instrument for disseminating scientific knowledge. Especially in this context, it is important that people’s learning encompasses more than the meanings of concepts and laws, involving aspects related to the ‘why’ and ‘for what purpose’ the knowledge was and is constructed. We consider these aspects as components of the sense, the connotative and subjective dimension of conceptual learning which encompasses a positioning of an individual towards a concept and its relevance in the physics framework. Motivated by this, in the present study, we investigated the senses ascribed to the concept of wave–particle duality (WPD) by 121 participants in a two-day (five-hour) science outreach minicourse in the double-slit experiment. Drawing on the ideas of Franco et al (2023, Cadernos de Pesquisa do Programa de Pós-graduação em Ensino de Física da UFRGS (Research Notebooks from the Postgraduate Program in Physics Teaching at UFRGS), Pimenta Cultural Editors S/A), we posit sensemaking as a type of cognitive effort to overcome a situation, viewed as a self-regulatory phenomenon wherein individuals self-observe, self-evaluate, and self-react to the situation to achieve a certain goal. In addition to identifying the senses attributed to the concept of WPD, we assessed the relationships between these senses and participants’ performance in a standardized test of this concept, as well as their educational background and field of study. Data were collected using questionnaires answered before and at the end of the course. The senses ascribed to the concept of WPD were investigated through similarity and cluster analysis based on responses to essay questions. The relationships among these senses, questionnaire performance, and educational background were evaluated using non-parametric statistical tests. We infer two senses attributed to wave–particle duality: (1) WPD is a basic and fundamental concept that impacts the way we comprehend the essence of nature, and (2) WPD is a very advanced concept restricted to the field of Quantum Mechanics. A statistically significant correlation (0.26 was identified between the senses attributed and participants’ performance on the standardized test, suggesting that the sense ascribed to a concept and performance in questions requiring its mobilization are overlapping elements but constitute two distinct dimensions of learning that need to be assessed simultaneously.

Crucial role of fungi in environmentally sustainable agriculture

To produce more, better and safer food we must be able to do so while promoting the sustainable use of agricultural resources. The increase in agricultural production is currently through the use of pesticides, fertilizers, and developments in plant breeding and genetic skills. In naturally existing ecosystems, rhizospheric soils have biological living beings to favor the plant development, nutrient assimilation, stress tolerance, disease deterrence, carbon seizing and others. Fungi are among the most widely distributed organisms on Earth and are of great environmental importance. Mycorrhizal fungi, bacteria, actinomycetes, etc. solubilize nutrients and assist the plants in uptake by roots. Amongst them, vesicular/arbuscular mycorrhizal fungi (AMF) have key roles in the natural ecosystem, as the majority of the terrestrial plants form association with AMF. This symbiosis confers benefits directly to the host plant’s growth and development through the acquisition of phosphorus (P) and other mineral nutrients from the soil. They may also enhance the protection of plants against pathogens, increase plant diversity and have the potential to enhance plant growth under stressful environments. In this article, the sustainability and environmental aspects of agriculture, and the basic concepts of fungi will be reviewed to justify our point of view about the tremendous importance of fungi towards an environmentally sustainable agriculture.

Numeracy Literacy Capability of Junior High School Students at Inamosol District

It is important for students to master numeracy literacy as part of the minimum competency assessment, in order to have the thinking skills needed in the 21st century. This research aims to describe the numeracy literacy abilities of junior high school students in mountainous areas. This research uses a mixed method. The data collected is quantitative in the form of numeracy literacy test results and qualitative data in the form of interview results to describe students’ weaknesses in numeracy literacy. The research results showed that student’s literacy skills still remain at levels 1 and 2. Less than 20% of students were at level 3, and there were no students at levels 5 and 6. The category of students is that intervention and basic literacy skills are needed. The qualitative analysis concluded that the cause of low literacy was low communication, mathematization, and representation skills. In terms of indicators of mathematical ability, there are various basic concepts that students have not mastered so they experience difficulty in solving mathematical problems. Apart from that the reasoning that occurs is still imitation in nature, students still tend to memorize and use standard and imperfect procedures. The strategy used only imitates the teacher’s strategy, while students have not used new strategies which causes literacy to still be at a lower level. Keywords: numeracy, literacy, numeracy literacy level, mountains areas

Cut-free labelled calculi and decidability for intuitionistic sentential logic with identity

Abstract In this paper we consider the intuitionistic non-Fregean sentential calculus with Suszko’s identity ($\mathsf{ISCI}$). After recalling the basic concepts of the logic and its associated Hilbert proof system, we introduce a new sound and complete class of models for $\mathsf{ISCI}$, called Topological Beth (${\mathsf{TB}}$) models, that can be viewed as algebraic counterparts (and extensions) of sheaf-theoretic topological models of intuitionistic logic. From this semantical study we define a family of sound and cut-free complete labelled calculi that capture both the Kripke and the ${\mathsf{TB}}$ semantics. Using a key property of the forcing relation in ${\mathsf{TB}}$ models, called regularity, we show termination and decidability results. Finally we discuss the automation of the proof search in one of the labelled calculi and its implementation.

This study aims to determine the effect of the use of interactive learning media (wordwall) on the understanding of basic mathematical concepts of grade IV students at SDN 1 Tebaban. This type of research is a quantitative research of experimental methods with a quasi-experimental design of pretest-posttest control group design. The population of this study is class IV A and IV B which totals 35 students. The sample of this study uses a saturated sampling technique. The data collection technique in this study uses observation sheets, questionnaire sheets and pretest and posttest test sheets. The data analysis techniques in this study include observation and questionnaire data analysis, descriptive analysis, normality test, variance homogeneity test and independent samples test. The results of the observation sheet showed that the students' understanding of basic mathematical concepts in the experimental class reached 75% ('Very Good'), higher than the control class which only reached 62.99% ('Good'). Based on the results of the questionnaire, the use of wordwall interactive media was proven to be more effective in improving students' understanding than mind mapping learning media and teaching aids in the control class, with 91% of students in the experimental class supporting the use of wordwalls, compared to 80% in the control class. The t-test showed a value of Sig. (2-tailed) 0.02, so that the alternative hypothesis was accepted, indicating a significant influence of interactive learning media on the understanding of mathematical concepts of grade IV students at SDN 1 Tebaban.

Political Epistemology without Apologies

AbstractPolitical epistemology has become a popular field of research in recent years. It sets itself the ambitious task to intertwine epistemology with social and political theory in order to do justice to the relationships between truth and politics, or reason and power. Yet many contributions either expand arguments and concepts from traditional epistemology to political phenomena or use existing theories and frameworks from social and political theory to address the politics of epistemological questions. The former approach (prominent, e.g., in the epistemic injustice debate) leads to an epistemisation of political phenomena and concepts coupled with their de‐politicization, the latter approach (prominent, e.g., in Frankfurt School critical theory) leads to a politicization of epistemic phenomena and concepts coupled with their de‐epistemisation. Instead, it is argued that political epistemology requires reworking even basic concepts, due to its three foundational commitments: It is committed to the claim that socio‐material conditions of existence matter epistemically (minimal materialism), to the self‐reflection of the socio‐material conditions of political epistemology's own arguments and theories (radical self‐reflexivity), and to a specific form of epistemic humility (epistemic non‐sovereignty). Using the notion of normativity as an exemplary problem, the article closes by highlighting the difficulty of maintaining these three commitments.

Research on the Development of LDO Chip Technology

Abstract. Whether portable electronic devices are powered by rectified AC mains or by batteries, the power supply voltage will vary over a large range during operation. In order to ensure a stable power supply voltage, almost all electronic devices must be powered by a voltage regulator. In order to meet the requirements of precision electronic equipment, a linear regulator should be added to the input end of the power supply to ensure a constant power supply voltage and achieve active noise filtering. LDO can help achieve this function. This article first introduces the basic concepts of low-dropout linear regulators and sorts out the advantages of low-dropout linear regulators. Secondly, the parameters that need to be studied for LDO are sorted out, which are also the direction for breakthroughs in LDO research. The third part introduces some basic structures of LDO, including the design of LDO structure without external capacitors, the design of bandgap reference LDO structure, and the design of high PRSS structure. Finally, the application of LDO is roughly summarized, as well as the trends and challenges of LDO development.

Solving Partial Differential Equations Using Fourier Series

This research paper aims to study the methods of solving partial differential equations using Fourier series. Partial differential equations are a powerful and practical tool in mathematics and physics to describe many phenomena and processes that involve continuous change at the level of equations and functions. The basic concepts related to the Fourier series and how to represent functions using it in the field of mathematics will be reviewed. Application examples of partial differential equations, such as waves, heat and diffusion, and how to use the Fourier series to solve them will also be presented. The steps of solving the partial differential equation using the Fourier series will be explained. The importance of Fourier series in the theory of partial differential equations is that periodic functions f(x) defined on (-∞,∞) or functions defined on a finite interval can be represented by an infinite interval of sines and cosines. In this research, the solution of the partial differential equation using the Fourier series was studied with the solution of an example.

Methods: as a part of the study, a comparative law method was used, which made it possible to identify differences in violations when using the image of a citizen; a systematic approach; a formal logical research method. Results: the analysis of the current legislation of the Russian Federation has been carried out, and the conditions associated with the formation of the statutory concept of the mechanism of the civil regulation of relations in the field of property turnover have been determined. Conclusions: it is determined that the basic statutory concept of the civil mechanism is formed taking into account the objectives of the activities of the participants in the turnover and can be supplemented depending on the circumstances. Such a statutory concept legally ensures the satisfaction of private interests. In case of violation of interests, the protective means of the mechanism of the civil regulation are used, which “help” to restore the property status of the injured party.

The theoretical concept of economic development at the present stage is the process of smartization and digitalization

The principal trends in economic development at the advent of the 21st century evince substantial alterations occurring as a consequence of the advent of cutting-edge technologies, globalization, and social transformation. These developments contribute to the efficiency, productivity, and competitiveness of economies, while simultaneously creating new opportunities and challenges for business and society. The principal trends in economic development at this juncture are the processes of «smartization» and «digitalization,» which have become indispensable prerequisites for economic advancement across all sectors of production and social activity. The digital transformation entails the integration of digital technologies into all facets of business and social activities. This includes the automation of business processes, the development of e-commerce, and the use of big data. At the same time, the smartization of cities and economies involves the use of intelligent systems to improve the efficiency of urban management, energy, transportation, and other sectors. The development of information technologies and the growth of artificial intelligence create conditions for economic transformation, and the integration of digital technologies into all spheres of life and economy can lead to changes similar to those that occurred as a result of the Industrial Revolution. In the long run, the smart economy may change not only the ways of production and consumption, but also social structures and the interaction between humans and machines. However, this raises the need for society to adapt to the rapidly changing technological reality and the importance of developing the skills that will be needed in the future digital world.The article identifies the features of digitalization and smartization as socio-economic phenomena that characterize the current stage of development of the global economy. The article analyzes the conceptual differences between digitalization and smartization as basic concepts of economic development and the current stage of its development and identifies the key characteristics of their implementation.

Value adding bioconversion of residues and byproducts—a logistics challenge

AbstractGlobal developments such as climate change, a growing world population and the depletion of fossil resources make the sustainable use of biogenic resources in chemical production inevitable. This would also provide a final product with a higher added value than just utilizing the raw materials for applications in energy generation. In recent years, many researchers have shown that e.g., grass clippings, carrots and potato peels can be biotechnologically converted into high-value chemicals thereby increasing resource efficiency. A particular challenge, however, is the decentralized production of such biogenic raw materials as well as degradation affecting the composition and quality within short periods of time. Therefore, appropriate logistics concepts must be developed and evaluated to economically valorize biogenic raw materials. Such concepts differ significantly in terms of material utilization for the production of chemicals, composting or energetic valorization. This overview presents relevant examples of the conversion of biogenic residues into chemicals investigating basic logistic concepts and highlighting major challenges along bio-based value chains.
