In contemporary design practices, the conflict between initial design approaches and subsequent manufacturing and construction stages presents a notable challenge. To address this disparity, our study aims to establish a comprehensive digital design workflow, bridging these gaps. The authors introduce a conceptual framework that seamlessly integrates the imperatives of LEED with the realm of robotic manufacturing, specifically tailored for construction sites. The proposed methodology encompasses four distinct iFOBOT modules: iFOBOT-environment, iFOBOT-design, iFOBOT-construct, and iFOBOT-monitor. The integration of these modules allows for a holistic approach to design and construction, fostering efficient collaboration between multidisciplinary teams. To validate the efficacy of the author’s approach, we conducted an empirical study involving the creation of a double-skin facade panel perforation using this integrated process. Initial findings emphasize the enhanced constructability achieved through simulated robotic interventions utilizing a heuristic function. Moreover, this research presents a functional prototype as a tangible embodiment of the method’s practical application and potential impact on the field of architectural design and construction.

Abstract. Rats are the main agricultural pests and one of the factors causing crop failure for farmers, especially in Pademawu. Farmers generally use pest control methods using poisons that can pollute the agricultural environment. The application of the Trap Barrier System (TBS) is needed to overcome the rat pestproblem. The service aims to increase partners' insight into implementing rat pest control using TBS. Community service activities in the form of outreach and training. The method used is descriptive quantitative, namely data collection through filling out questionnaires including knowledge skills, level of interest, posttest and pretest for partner knowledge evaluation. The results of the participant's assessment of the benefits of the training through Evaluation of farmers' understanding of the application of TBS technology showed results of 82%. The assessment shows the skills and insights obtained by the farmers are in the good category after carrying out the activities. The participants also showed interest in participating in the activities shown by the participants actively asking and listening during the discussion. TBS has been proven to be able to reduce the level of rat attack on rice by up to 80% so that farmers are interested in using the TBS trap system. Even so, the TBS system cannot break the life cycle of rats and further guidance is needed regarding sustainable cropping and cultivation patterns to overcome this in the farmers' environment in East Pademawu Village.

Products derived from wheat grains are an important source of protein in the daily diet of people in many parts of the world. The biological value of protein is determined by its amino acid composition and the proportions of the individual amino acids. Synthesis of these compounds in wheat grains is influenced by genetic factors, as well as habitat conditions and the agrotechnology applied in cultivation. The aim of this study was to assess the effect of production technology (integrated, intensive) on the grain yield and the content amino acid profile of protein in common and durum wheat grain. Field research was conducted at the Experimental Station IUNG-PIB in Osiny (Poland) in two growing seasons. It was found that grain yield significantly depended on the weather conditions in the years of harvesting and genotype, but did not depend on the production technology. On the other hand, the protein content and their amino acid composition depended significantly on the production technology and genotype. A significantly higher content of protein substances was found in durum wheat grain. Increasing the intensity of production technology had a positive effect on the total protein content and the content of individual amino acids, both exogenous and endogenous. The amino acid limiting the biological value of protein contained in grains of both wheat species was lysine, and the deficiency of this amino acid was significantly lower in grain protein from intensive than integrated cultivation technology.

The possibility of using technogenic titanium-containing waste from the enrichment of apatite–nepheline ores to obtain import-substituting functional products, in particular fillers for temperature-controllable sealing agents used in advanced branches of technology (shipbuilding, aircraft, and rocket manufacturing), is examined. The method developed is based on the different solubility of the mineral components contained in the waste in hydrochloric acid medium, which makes it possible to separate titanite from apatite and nepheline by sequential processing at the first stage and to separate the titanosilicate precipitate from titanite (a precursor to obtain a filler) at the second stage. It is shown that the neutralization of the hydrochloric acid effluents formed after the first stage of treatment with ammonia water at pH 7–12 provides almost complete precipitation of the aluminum and calcium in them as hydrophosphate amorphous phases and of the silicon as silica. The phase composition of the precipitate obtained remains almost unchanged during its heat treatment (T = 500°C). There is only a decrease in the specific surface area of the particles, which indicates the compaction of its structure. It is recommended to use the sediment thus obtained as an additive to increase the strength of concrete. [ABSTRACT FROM AUTHOR]

Large and complex ring forgings are key structural parts of the aerospace field, and their quality is closely related to the reliability of aerospace vehicles. However, high-quality production of aerospace ring forgings faces many problems, such as the long process design cycle and impoverished consistency, the difficulties of real-time detection under the severe time-varying state of the deformation process, the complexity of high-quality non-destructive testing under multitudinous defects, and the cumbersome management control of the multi-source and multi-dimensional heterogeneous data. Considering the current situation of multi-variety and multi-batch production for aerospace ring forgings, establishing an intelligent production line is a crucial means to solving the above problems and realizing the standardization and premiumization of key aerospace components. Therefore, management control and integration technology of the intelligent production line play a crucial role. An analysis, including the research progress of the intelligent computer-aided process planning (CAPP) system, the real-time detection and control system, the product quality testing system, and the intelligent management control and integration system, is systematically reviewed in this work. Through intelligently managing and controlling the integrated systems of the production line, the production efficiency of ring forgings can be effectively improved, and the production energy consumption can be remarkably reduced, which is of great significance for enhancing the manufacturing technology level of aerospace products.

In order to solve the current two major environmental problems of urban waste pollution and surface subsidence above the coal mine goaf, the technology of sealing and backfilling the goaf with urban waste is proposed. This technology takes "waste disposal" and "goaf backfilling" as the theme. Aiming at the processing of loose waste, the waste drying and briquetting integrated machine is designed, the entire processing technology ensures the strength of the loose waste materials and no filtrate. For the processing of solid aggregate waste, it is crushed into recycled concrete raw materials for goaf backfilling. Aiming at the goaf backfilling, the goaf backfilling coal mining method is designed, the backfilling hydraulic support is modified, and the backfilling mechanism is added to realize the integration of "mining-backfilling" in the working face. The backfilling technology embodies the key issues of the sealing of the backfilling space and the strength of the backfilling body with "three times of sealing" and "three times of strengthening". Using urban waste as the backfilling materials for the goal area, the waste pollution and the surface subsidence are turned into "two benefits", and the construction of waste-free cities and green mines is promoted.

In this study, we propose an innovative approach to regulate municipal solid waste (MSW) resource utilization and renewable energy conversion. Under the concept of circular economy, clean anaerobic digestion (AD) and gasification are combined to form integrated technology to achieve sustainable waste-to-energy. A matched multi-objective optimization model is developed to balance the economic and environmental benefits during the waste-to-energy process under uncertainty. Robust optimization is used to produce optimal solutions that are feasible even in the worst-case scenario in terms of uncertain parameters. The practicality of the proposed methodology is tested in a real-world case, and it is found that utilizing integrated technology can effectively carry out MSW resource utilization while also obtaining ample renewable energy. Robust optimization is used to conduct scenario analyses on the fluctuation interval of the uncertain electricity subsidy in order to assess its impact on the model solutions. It was found that the cost and carbon emission objectives were highly sensitive to changes in electricity subsidy. Although AD has been the primary technology used for waste-to-energy, the use of gasification in integrated technology has been increasing. While the treatment plans of various MSW types were different, there were still some commonalities. [ABSTRACT FROM AUTHOR]

The main pollution components of coke oven flue gas are SO2 and NOx. The SO2 and NOx not only harm human health, but also cause serious environmental pollution. Combined with the new type of denitration catalyst, magnesium flue gas desulphurization process and radial heat pipe waste, heat boiler and other core patented technologies, this paper creatively put forward the integrated technology of coke oven flue gas desulphurization, denitration, and waste heat recovery and utilization. This method can fundamentally solve the problems of environmental pollution caused by coke oven flue gas emission and waste heat recovery and utilization in China. The denitration efficiency is always stable above 98%, which reflects the super-high denitration efficiency of catalyst. It not only has the remarkable economic efficiency, but also has huge social efficiency. [ABSTRACT FROM AUTHOR]

The ever growing concerns about the impact of first generation bioethanol on food chain and on biodiversity have shifted the focus of research to second generation (2G) bioethanol technologies. The 2G-bioethanol's production relies on biomass feedstock that could provide a more sustainable energy generation without compromising food security and environment. Indeed, this production process exploits non-food crops, food crops residues, wastes of wood-based or food-based industries such as wood chips, skins or pulps from fruit pressing, respectively. Nevertheless, the industrial process of 2G-bioethanol's production is still in its infancy, indeed the future and the sustainability of the 2G-bioethanol strongly depend upon the development of the current technology. In this paper particular attention will be paid to the role of thermophilic microorganisms and their enzymes to the biotechnology's development of the bioethanol's production process.

Elementary school students in Indonesia are required to learn to play traditional musical instruments, one of which is angklung (a bamboo musical instrument). However, they might have difficulty in playing angklung because angklung is a type of musical instrument that comes in an ensemble, so it must be played collaboratively. This paper aims at providing a solution for learning to play angklung easily by designing a technology-based touch angklung and implementing it in the classroom. Several computer applications and hardware were integrated to develop the touch angklung. The applications used are Sibelius, Kontakt, Sound Forge Audio Studio, and Scratch. Meanwhile, the hardware used is the MakeyMakey Kit (MMK). The development of the touch angklung comprised of sampling the angklung sounds, making angklung sound buttons on the computer, redesigning the angklung, and assembling the MMK with angklung. The touch angklung was implemented in the classroom in two schools, which consist of 30 students. Each student participated in a survey to identify the results of learning to play traditional musical instruments using the touch angklung. Observations were also carried out by the teachers and researchers. The results showed that the students had high motivation to play the touch angklung. They could play song compositions easily based on the melodies of the songs they have memorized. In conclusion, learning traditional musical instruments is more attractive to students when integrated with technology. [ABSTRACT FROM AUTHOR]

Abstract In this study, the performance of an integrated technology, combining biological treatment with advanced oxidation process in sequence, was evaluated for the degradation of sulfolane in aqueous media. In addition, the impact of biological process on AOP was also studied by assessing residual sulfolane, nutrient and total suspended solids (TSS) concentrations. The integration of activated sludge process with UVC/H 2 O 2 resulted in more than 81% of sulfolane degradation in less than 24 h. It was observed that mineralization was much faster in biological system compared to AOP. Mechanistically, the process of degradation is different in the two processes as various by-products were identified during UVC/H 2 O 2 but not during the biological process. The impact of residual sulfolane concentration on UVC/H 2 O 2 was significant beyond a concentration of 30 mg L−1, while below 30 mg L−1 the rate of degradation was independent of sulfolane concentration. Residual nutrients from biological systems did not impact AOP performance. Nevertheless, presence of TSS >44 mg L−1 had a negative impact on the performance of UVC/H 2 O 2 by reducing UV transmittance which led to retardation of sulfolane degradation. The application of UVC/H 2 O 2 after biological treatment was an advantage as UVC/H 2 O 2 could perform dual roles of oxidant and disinfectant. Graphical abstract Image 1 Highlights • Integrated activated sludge - UV/H 2 O 2 treatment can effectively degrade sulfolane. • Residual nutrients do not affect UV/H 2 O 2 performance. • High initial sulfolane and biomass concentration can impact UV/H 2 O 2 performance. • Sulfolane is absorbed by microbes prior to being metabolized. • UV/H 2 O 2 can degrade sulfolane and disinfect post biotreated water simultaneously.

Abstract The aim of this work was to enhance the continuous supercritical biodiesel production process by applying the co-solvent technology. The influence of co-solvent types on the fatty acid alkyl esters (%Ester) or biodiesel content was primarily evaluated. Experiments were performed through the transesterification of palm oil and ethanol in a microtube reactor under the supercritical solvent conditions. Three different polarity levels of co-solvent including tetrahydrofuran, acetone, and iso -propanol were selected. Results indicated that each co-solvent added to the reacting system significantly enhanced the homogeneity of the mixture. The influence of co-solvent type was clearly observed and became small at high reaction temperatures and long residence time. The %Ester was higher than 80% with the addition of any types of co-solvent under the residence time of 3.5 min, co-solvent amount of 20%, reaction temperature of 350 oC, and alcohol-to-oil molar ratio of 23:1, whereas 65.6% of ester content was obtained in the absence of co-solvent under the same operating conditions. The use of acetone as co-solvent provided the highest %Ester; however, further studies in different perspectives such as biodiesel properties, co-solvent separation method, and economic impact should be considered to select the optimized co-solvent for improving the biodiesel production.

Aromatic compounds have received widespread attention because of their threat to ecosystem and human health. However, traditional physical and chemical methods are criticized due to secondary pollution and high cost. As a result of ecological security and the ability of carbon sequestration, biodegradation approach based on microalgae has emerged as a promising alternative treatment for aromatic pollutants. In light of the current researches, the degradation efficiency of BTEX (benzene, toluene, ethylbenzene, and xylene), polycyclic aromatic hydrocarbons (PAHs), and phenolic compounds by microalgae was reviewed in this study. We summarized the degradation pathways and metabolites of p -xylene, benzo [a]pyrene, fluorene, phenol, bisphenol A, and nonylphenol by microalgae. The influence factors on the degradation of aromatic compounds by microalgae were also discussed. The integrated technologies based on microalgae for degradation of aromatic compounds were reviewed. Finally, this study discussed the limitations and future research needs of the degradation of these compounds by microalgae.
