Promoting Sustainability through the Recycling and Reutilization of Polyethylene Packaging

Abstract The outstanding performance and low carbon footprint of polymeric materials conflict with the sharp growth in plastic trash, which is why the current global plastics economy is largely linear. Reducing environmental problems requires a shift to a circular economy that keeps plastic in its most valuable state and encourages reduction, reuse, and recycling. The existing mechanical recycling procedures are constrained by cost, deterioration of mechanical qualities, and uneven product quality, but mechanical recycling is a crucial instrument in an environmentally and economically sustainable economy of plastics. Through the lens of a circular economy, it’s important to properly sort and recycle (PE) packaging to ensure its maximum potential for reuse. In this paper it discusses the optimum ratio between the recycled and raw (LDPE) pellets in order to create a plastic packaging with the same mechanical, physical and chemical properties with less cost in comparison to the ordinary one. Fourier Transform Infrared Spectroscopy (FTIR) and Energy Dispersive X-ray Spectroscopy (EDX) were used to characterize both raw and recycled (LDPE) pellets. The environmentally friendly LDPE nano-particles in polymer packaging will be tested in the second experimental section, and the results will be compared with those of regular polymer packaging.

Концепция бережливого производства в контексте обеспечения экономической безопасности предприятия электроэнергетики

The article substantiates the effectiveness of disseminating the philosophy of lean production at electric power enterprises. It is shown that the methods of the concept under consideration give a positive effect when applied in combination. Destructive factors that generate losses, overload, and uneven production are also present in the activities of electricity enterprises. Adaptation of lean production methods to the specifics of the functioning of energy companies makes it possible to level out the unproductive expenditure of enterprise resources. By reducing the cost of electricity generation, energy companies are able to reduce the cost of electricity generation while maintaining the quality and volumes generated. At the same time, there is an improvement in a number of indicators that form the cost of production, which has a beneficial effect on the level of economic security of the enterprise.

Analysis of Chemical Changes during Maturation of Amomum tsao-ko Based on GC-MS, FT-NIR, and FT-MIR.

Amomum tsao-ko Crevost et Lemaire (A. tsao-ko) is widely grown for its high nutritional and economic value. However, the lack of a scientific harvesting and quality control system has resulted in an uneven product quality. The present study was based on A. tsao-ko from four maturity stages from the same growing area, and its chemical trends and quality were evaluated using a combination of agronomic trait analysis, spectroscopy, chromatography, chemometrics, and network pharmacology. The results showed that A. tsao-ko was phenotypically dominant in October. Spectroscopy showed that the absorbance intensity at different maturity stages showed a trend of October > September > August > July. Further chemical differences between A. tsao-ko at different stages of maturity were found by chromatography to originate mainly from alcohol, aromatic, acids, esters, hydrocarbons, ketone, heterocyclic, and aldehydes. The network pharmacology results showed that the active ingredient for the treatment of obesity was present in A. tsao-ko and had high levels in A. tsao-ko in September and October. The results of this study provide a new idea for the comprehensive evaluation of A. tsao-ko and a theoretical basis for the harvesting and resource utilization of A. tsao-ko.

Cluster approach to regional oil and fat subcomplex development

The article studies regional oil and fat subcomplex development in terms of the cluster approach application based on coordinating economic interests of sunflower seed producers, processing and marketing organizations under the condition of appropriate government support, as well as methodological, organizational, and information support by the relevant structures. On the basis of the production and economic indicators analysis it has been revealed that in the Saratov region sunflower production is quite effective, but the lack of interconnection between the oil and fat subcomplex subjects leads to uneven production volumes and highly varying profitability in the context of municipal districts of the region and lost profits formation at all stages of product movement. The author has developed a scheme of the regional oil and fat cluster subjects territorial location, represented by the areas of the cluster production core (with sunflower production volumes above the average regional level), production linking areas (with sunflower production volumes below the average regional level), as well as areas with developed infrastructure (with the presence of processing and storage facilities, and transportation hubs), allowing to establish an effective logistics system with mutually beneficial cooperation between regions. On the example of sunflower seed producers in the Saratov region clustering efficiency has been shown, which consists in production costs reduction as a result of transaction costs reduction and sales revenue growth due to the increase in the sunflower purchase price. The study results can be used in programs and proposals development to strengthen integration ties between the agro-industrial complex subjects.

Patagonia’s Substandard Brand Awareness in China

Patagonia has consistently employed marketing methods that deviate from conventional approaches. Nevertheless, its performance in the Chinese market has consistently fallen below expectations. The objective of this research is to examine the factors contributing to the limited recognition of Patagonia within the Chinese market. This study examines the diverse factors that exert influence on the level of brand awareness of Patagonia in the Chinese market. By doing a comprehensive analysis of several published papers and reports, one notable source being an article titled "Competitive Advantage through Product Performance Innovation in a Competitive Market" published in the Journal of Product Innovation Management, it has been identified that there exists a weakness in Patagonia's product innovation strategy as observed in its recent product launches. The study findings indicate that Patagonia's underwhelming success can be attributed to insufficient promotional techniques, uneven product innovation, and a dearth of distinctive brand identity. Furthermore, the strategic utilization of social media, collaborative partnerships with other brands, heightened allocation of resources towards research and development, innovative designs, improved product positioning, and a more explicit articulation of brand values serve to address the challenges that Patagonia encounters while entering the Chinese market. This study asserts that Patagonia's advancement in the Chinese market has been impeded by three primary factors: inadequate marketing techniques, limited product innovation, and a lack of a distinct brand identity. Therefore, in order to surmount these obstacles, it is imperative for Patagonia to adopt and execute the answers and recommendations outlined in this research.

Urban Political Ecology in Mexico: Metabolism, conflicts, and the need for transformational pathways in the Valley of Mexico, Guadalajara, and Monterrey

This article analyzes urban socio-ecological conflicts in the Mexican metropolitan areas of the Valley of Mexico, Guadalajara and Monterrey from an Urban Political Ecology (UPE) approach. We identify the main triggers of such urban socio-ecological conflicts and the causal links between actors, resources and spaces which make up the uneven production of urban space. This focus includes unequal access to resources, uneven distribution of environmental impacts, and the rise of contestation. We outline UPE theoretically and conceptually, and delineate what is meant by urban socio-ecological conflict. UPE is then contextualized within Mexico's contemporary urbanization process as a prelude for characterizing case studies (including their metabolic profiles) and the analysis of prevailing socio-ecological conflicts. For the latter, we identify the main urban conflicts in the years 2012 and 2022, highlighting some of the main characteristics, similarities, and discontinuities across three metropolitan areas. In the face of an increasing metabolism of contemporary urbanization, we conclude with a brief consideration of the potential role of socio-ecological conflicts for enabling alternative forms of urban space production, particularly through the agency of social movements, including their capacity to propose and build "urban spaces of hope."

Laboratory studies of induction of flow using vibratory wave draining in carbonate low-permeability reservoirs

The object of the study is a laboratory unit for inducing flow to the well using vibration wave draining in carbonate low-permeability reservoirs. Vibratory wave draining is a method used to stimulate flow draining to the well. The method is based on the fact that mechanical waves generated in the soil can cause the opening of microcracks and pores, which leads to an increase in the fluid flow. Vibratory wave scouring can be effectively used to increase fluid flow in low-permeability carbonate reservoirs. Carbonate reservoirs are a common type of reservoir in the oil and gas industry. They often have low permeability, which makes it difficult to extract fluid. With the help of the plunger device developed in the work, a fluid disturbance was created, thereby creating elastic waves in the conventional well (plastic pipe), which were measured using a manual contact vibrometer. This demonstrated the effectiveness of the vibratory method to increase the well productivity and helped to improve the permeability of the rocks, providing better access to challenge the influx of hydrocarbon products. It is shown that with a significant decrease in the permeability of the formation well zone (FWZ), the flow induction should be started only after the restoration works. Otherwise, the well will be significantly hydrodynamically imperfect due to the quality of the reservoir opening, and the flow of production into the well will occur only through a few separate areas of the reservoir with relatively high permeability, which will lead to uneven production of the reservoir and low return of hydrocarbons. Therefore, it is advisable to use the developed method of influencing the productive layer in low-permeability rocks, such as carbonates with layers of clay, siltstones, argillites, and others, with low formation pressures. The obtained results are based on the generation of vibrations that are transmitted to the wellbore. These vibrations can help break up contaminants and fines in carbonate rocks, facilitating the release of hydrocarbon products and improving permeability.

Anticipatory planning for equitable and productive curbside electric vehicle charging stations

Two challenges to planning public electric vehicle (EV) charging networks remain in U.S. cities, including uneven productivity of charging stations and inequitable charging access across user groups. The unpredictable EV market penetration over the long term further complicates the relevant infrastructure planning. However, the extant planning approaches are limited in addressing both challenges simultaneously when considering future uncertainties. Therefore, we propose a data-driven anticipatory framework to plan for EV charging station allocation near urban amenities based on charging-while-parking behavioral patterns. We focus on two user groups, i.e., multi-family and single-family residents. We compare the productivity-equity outcomes of allocation scenarios under three planning strategies and four possible ratios between both user groups. The framework addresses the incremental charging demands at different market levels for each scenario. An in-depth case study of Alachua County, FL, shows that over-emphasizing multi-family charging demands when placing EV charging stations may undermine their overall productivity. We then suggest three pathways to balance equitable access and optimized productivity for the community based on the comparison of planning scenarios. The proposed framework is generalizable to other EV-initiating communities. This study sheds light on future-oriented adaptive planning for transportation infrastructure during the energy transition.

Understanding the Quantitative Matching Principle of Reaction and Distillation for the Reactive Distillation Process of Cyclohexyl Acetate Synthesis

The matching problem of reaction and separation in reactive distillation (RD) is an urgent problem, and the main reason for little relevant research is that there is no suitable RD for experiments. To understand the matching principle, this work designed KRD001#SCPI and HY@SiC catalytic packings, which tend to different coupling ratios of reaction and separation. The pilot-scale RD experiments and corresponding simulation of cyclohexyl acetate production were studied to verify matching coupling of different reaction RD requirements. Upon verification of this, conventional RD processes were considered from economic, environmental, and energy perspectives, and a new matching form of RD was further proposed based on uneven product distribution. For a ternary reaction system where product was heavy, product concentration moved downward, catalytic packings with high reaction rates were needed at lower reaction sections to avoid a reverse reaction, and those with high separation efficiency are needed at the upper section to separate product and reactants better.

Strengthening the science–policy interface in the climate migration field

AbstractThe question of how climatic changes and hazards affect human mobility has increasingly gained prominence in public debates over the past decade. Despite improvements in the scientific understanding of the subject and advancements in policy, major gaps remain in addressing the humanitarian and socio‐economic challenges related to climate migration. In this perspectives article, we argue for a holistic approach and a closer integration of science and policy involving diverse stakeholders in the process of knowledge generation and implementation. We identify five key challenges characteristic for improving the science–policy interface: (i) conflictual political contexts and the securitization of human migration, (ii) simplistic narratives and framing of the subject, (iii) the uneven production and dissemination of knowledge, (iv) limited data and analytical capacities and (v) a selective topical and methodological focus. To address these diverse challenges, there is a need for more bridging initiatives at the science–policy interface that integrate diverse disciplines, approaches and stakeholders. A closer engagement of researchers and policymakers in the form of multi‐stakeholder exchanges, capacity‐building activities, co‐development and co‐implementation processes and integrative scientific assessments can help bridge the gap to support the inclusive generation of knowledge and the development of comprehensive policies.

Provincial

This essay sketches out how “the provinces” became a central (if semi-imagined) geography in nineteenth-century culture, usually opposed to—though ultimately inextricable from—the development of capitalist and colonial modernity. Surveying recent criticism on the Victorian provincial novel, especially its imbrication with broader scales and networks, I suggest that recent scholarship in critical cartography and feminist theory offers a way to reconceptualize the notion of the provincial in (and beyond) Victorian studies. If to be provincial is always to be opposed to some real or imagined center—toggling between countryside, colony, region, and minor capital—we might revise our understanding of the provincial itself as a relational phenomenon, unfolding on multiple scales. Ultimately, I propose the “provincial” as a critical heuristic for the spatial analysis of narrative: one that might offer a more productive means of grasping modernity's uneven production of space beyond city/country, metropole/colony, and even local/global divides.

Evaluation and development of a method for compensating the positioning error of computer numeric control equipment

In the manufacturing process, Computer Numerical Control is widely used to process products that require a high level of accuracy. It is found that during product processing, Computer Numerical Control is still unable to fully counteract the influence of vibration and the presence of uneven product surfaces. In this paper, the stabilization mechanism developed, known as the Modified Stewart platform, which has a 3 Degrees of Freedom and can rotate around the X and Y axes and move translationally along the Z axis. This platform can be used to improve the accuracy and stability of the Computer Numeric Control tool. In this research, the positioning accuracy of the Modified Stewart platform has been evaluated. In this research, a mock-up or prototype and a simulation model of the Modified Stewart platform was developed. The data to be studied is the inclination angle of the platform. In the experiment, to determine the positioning error, the variable being changed acquires not only the linear movement, but also the angle of the X-Y plane. By changing the angle contained in the X-Y plane, it can be seen the influence of the X-Y angle on the position error or angle of the Z-A plane. The simulation was carried out on MATLAB. The mathematical model in this study is to find the platform position or angle. To simplify the calculation, the Modified Stewart platform was depicted in the form of a trapezoid. The results of the angle in the simulation will be compared with the result of the angle on the mock-up Modified Stewart platform. The trapezoidal parameter used in the simulation corresponds to the parameters on the mock-up modified Stewart platform. The simulation provided information about the angle of inclination, height, length of its sides, and the relative length of sides. It was found that the position or angle movement of the platform is in accordance with the calculation or simulation model that has been developed, and the positioning error data of the platform is very small and it changes constantly. It should be noted that the presented method can be used to evaluate the platform positioning error and consequential calibration of the mechanisms with spatial kinematic. The positioning error at various mobile links positions is changing, but during the movement in just one direction it remains almost constant. The position error caused by the platform mechanism can be minimized by redesigning the platform and using components that can provide a much more precise movement, moreover, using the preliminary measurements it is possible to build a table containing corrections for the control program to access the correct position of the moving platform. The accuracy and the stability of its movement can be improved and the platform can be applied to Computer Numerical Control. The method developed allows to estimate the moving platform positioning error of the mechanism with spatial kinematic. Thus, the method developed can be eliminated or compensated. It is possible to calibrate the moving platform movements in automatic mode as well.

PRODUCTIVITY ANALYSIS OF SPLIT STONE PRODUCTION USING OBJECTIVE MATRIX (OMAX) METHOD (A Case Study)

One of the building materials that has a high business prospect is split stone. Some building material management companies in one of their departments produce split stone, which in its production there are several types of products based on size to meet various consumer demands. In production, especially in the 2021 period, there will be fluctuating or uneven production levels, where in one month there will be high production, and in another period there will be a decrease in production. Based on this, this study aims to analyze the calculation of productivity to identify what factors cause the productivity of split stone production to fluctuate. This research was assisted by using the objective matrix (OMAX) and fault tree analysis (FTA) methods. the results of the productivity recapitulation found that the attendance data component obtained an average score of 2.3 which is the lowest average when compared to other components. therefore with these results, attendance is the strongest factor affecting fluctuating productivity.

Exogenous Zeaxanthin Alleviates Low Temperature Combined with Low Light Induced Photosynthesis Inhibition and Oxidative Stress in Pepper (Capsicum annuum L.) Plants.

Low temperature combined with low light (LL) affects crop production, especially the yield and quality of peppers, in northwest China during the winter and spring seasons. Zeaxanthin (Z) is a known lipid protectant and active oxygen scavenger. However, whether exogenous Z can mitigate LL-induced inhibition of photosynthesis and oxidative stress in peppers remains unclear. In this study, we investigated the effects of exogenous Z on photosynthesis and the antioxidant machinery of pepper seedlings subject to LL stress. The results showed that the growth and photosynthesis of pepper seedlings were significantly inhibited by LL stress. In addition, the antioxidant machinery was disturbed by the uneven production and elimination of reactive oxygen species (ROS), which resulted in damage to the pepper. For example, membrane lipid peroxidation increased ROS content, and so on. However, exogenous application of Z before LL stress significantly increased the plant height, stem diameter, net photosynthetic rate (Pn), and stomata, which were obviously closed at LL. The activities of antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), mono de-hydroascorbate reductase (MDHAR), de-hydroascorbate reductase (DHAR), ascorbate peroxidase (APX), and ascorbate oxidase (AAO) improved significantly due to the increased expression of CaSOD, CaCAT, CaAPX, CaMDHAR, and CaDHAR. The ascorbic (AsA) and glutathione (GSH) contents and ascorbic/dehydroascorbate (AsA/DHA) and glutathione/oxidized glutathione (GSH/GSSG) ratios also increased significantly, resulting in the effective removal of hydrogen peroxide (H2O2) and superoxide anions (O2•−) caused by LL stress. Thus, pre-treatment with Z significantly reduced ROS accumulation in pepper seedlings under LL stress by enhancing the activity of antioxidant enzymes and accumulation of components of the ascorbate–glutathione (AsA–GSH) cycle and upregulated key genes in the AsA–GSH cycle.
