Strain Engineering of Ion-Coordinated Nanochannels in Nanocellulose.

Expanding the interlayer spacing plays a significant role in improving the conductivity of a cellulose-based conductor. However, it remains a challenge to regulate the cellulose nanochannel expanded by ion coordination. Herein, starting from multiscale mechanics, we proposed a strain engineering method to regulate the interlayer spacing of the cellulose nanochannels. First-principles calculations were conducted to select the most suitable ions for coordination. Large-scale molecular dynamics simulations were performed to reveal the mechanism of interlayer spacing expansion by the ion cross-linking. Combining the shear-lag model, we established the relationship between interfacial cross-link density and interlayer spacing of an ion-coordinated cellulose nanochannel. Consequently, fast ion transport and current regulation were realized via the strain engineering of nanochannels, which provides a promising strategy for the current regulation of a cellulose-based conductor.

Evaluation of the Influence of Water Content In oil on the Metrological Performance of Oil Flow Measurement Systems

According to current Brazilian regulations, if the volumes of oil produced used as a reference for the payment of government shares and third parties contain a water content greater than 2% v/v, these volumes must be arbitrarily increased between 1.44% and 10.89% due exclusively to water content, which has caused operational problems for oil companies such as differences between volumes produced and volumes sold, and additional payments from government shares and third parties. This study aimed to evaluate the metrological performance of oil measurement systems with ultrasonic, Coriolis and positive displacement flow meters when subjected to varied water content, fluid temperature and flow rate conditions using the Design of Experiments and the Response Surface Methodology. The analysis of variance showed that the models presented good fits for the ultrasonic meter (coefficient of determination R2 of 97.96%, p-value of 0.001, and a standard deviation of 5.89 × 10−5); Coriolis meter (R2 of 90.91%, p-value of 0.037, and a standard deviation of 5.88 × 10−5); and positive displacement meter (R2 of 99.07%, p-value of 0.000, and a standard deviation of 4.85 × 10−5). The results of the experiments carried out indicate that the contribution of each parameter analyzed to the metrological performance of the measurement system varies depending on the measurement technology used by the flow meter. However, the fluid temperature proved to be a relevant parameter common to all flow measurement technologies evaluated. All measuring technologies evaluated were influenced by water content in the range of 0% to 10% v/v, with the measurement error being less than 0.2% when compared to a standard positive displacement type meter in almost all experimental conditions. The Coriolis-type flow meter was the one that presented the smallest error among the measuring technologies evaluated.

Quantitative risk assessment of gas leakage and explosion in open kitchens and partitioned kitchens

ABSTRACT In recent years, natural gas companies have faced more and more gas supply applications for open kitchens in China. However, natural gas cannot be utilized in open kitchens according to the current compulsory regulations. The numerical models for three typical open kitchen layouts and the corresponding partition kitchen layouts were developed, respectively. The experimental setup of gas leakage and explosion, like a residential kitchen, was established based on the similarity theory. The accuracy and reliability of numerical models have been validated by three sets of experiments. An innovative quantitative risk assessment method was proposed to quantify the integrated risks for the open kitchen layout and the partition kitchen layout. The effectiveness of the proposed risk reduction measures was assessed using a modified LOPA (i.e. Layer Of Protection Analysis). The results show that the integrated risk for the open kitchen layout in different apartments is 1.37 ~ 4.65 times than that for the partition kitchen layouts. The integrated risk of gas leakage explosion in three open kitchen layout arrangements was reduced by 94.8%, 50%, and 94.5%, respectively, by setting two layers of protection. Meanwhile, the increased expense of ¥400 can be generally acceptable for the majority of residential users. The achievements could provide theoretical and technological guidance for gas safety supply in open kitchens.

How social innovations emerge in a rigid regulatory context: the case of demand responsive transport in Switzerland

ABSTRACT Demand responsive transport (DRT) solutions may improve rural transport systems. These solutions often emerge as social innovations in rural areas. In Switzerland, their planning process is embedded in a rigid regulatory framework of the public transport system. The objective of this paper is to understand in which way the regulatory framework of the public transport system influences planning processes of a DRT solution in a rural setting. The methodological approach of social innovation biographies helps to examine the necessary planning steps to start mybuxi, a DRT in two Swiss rural municipalities. Our findings show that regulatory constraints dominate the final planning stage of the social innovation. Protections of current public transport regulations hinder federal offices from subsidizing the DRT, having direct implications on the financial sustainability of the system. The findings of this paper help actors to better address regulatory questions in the early stage of the respective innovation process.

Cyclical issues of pricing of regulated services

The article reflects current issues of the formation and regulation of tariffs that have developed in the modern economy. A brief analysis of the historical development of tariff regulation with the assessment of the used methods and ways is conducted. The authors identified expediency of tariff formation and regulation by a single body determining functions and set tasks. The study uses descriptive, analytical, and comparative methods. The article describes a positive example of applying the practice of deregulation with subsequent possible extension to other areas. The reasons of inefficiency of using the marginal indices mechanism are determined and justified, which is directly related to underfunding of the industry and lack of investment components. The question is raised about the fulfillment of the development, or social function by tariff regulation. It is proved that the current tariff system is not able to change the situation of increasing the investment base necessary to stabilise the deterioration of infrastructure. The main components of the current tariff regulation system are identified, and the directions of a new development model are proposed with consideration to the problems found by the study. According to the research results, conclusions are given that reflect the essence of the designated topic for possible solutions to issues existing in the functioning development model.

Rectification and converter control of the FPSLGs for energy storage applications

AbstractThis article presents two power converters with controllers attached to the Free‐Piston Stirling Linear Generator (FPSLG) and energy storage system (ESS). The rectifier uses hysteresis‐SVPWM current regulation and CB‐SPWM, while the buck‐boost converter utilizes the dual‐loop PI control method. The storage battery receives energy from a linear‐generator with a rectifier and converter. The FPSE and linear motors in the FPSLG convert thermal to electrical energy. A two‐level electrical energy conversion technique using a three‐phase AC signal to DC and DC‐DC converter has been devised to reduce output electrical energy oscillation as well as stabilize the generating system's DC power. Initially, the FPSE's nonlinear model and the three‐phase permanent magnet linear‐motor's linear mathematical model were created and followed by the ESS and control mechanism simulation. The simulation shows that the ESS system and control approach can give stable power to the storage battery using linear‐generator power. The PR controller replaces the PI controller in the position loop to improve frequency and displacement tracing. The control system design was simulated in MATLAB and the topology's feasibility and correctness were confirmed. Comparative analysis shows that, rectifier uses the H‐SVPWM's unity power factor of AC and stability controllability of the DC‐side voltage is better than the CB‐SPWM approach.

Tourism Development and Urban Landscape Conservation in Rural Areas: Opportunities and Ambivalences in Local Regulations—The Case of Spain

This article analyzes local-level normative regulations aimed at directly or indirectly conserving the urban landscape in rural areas. Using a discursive analysis methodology on regulatory documents being enforced in a series of localities assigned to a tourism promotion program, the evidence suggests that promotional activity retroactively influences the phraseology of these municipal regulations. The results obtained point to the existence of perpetuating historicist approaches within the current regulations, which appear to largely derive from the search for success in the tourism market and the resulting benefits to the local economy.

Educational language policy for refugee-background students in the spotlight

This article maps the differences between the European Union’s Framework of Human Rights and state-based legal mindsets (ideologies) of language policy and planning in education. Based on the analysis of the documents released by the European Commission, the Council of Ministers and the European Council in the course of the constituting of multilingual perspective and taking the experience of its local implementation into account, this article examines common cross-state indicators in order to compare multilingual responsibility of public education policies for refugee-background students (RBSs). It concludes that the assessment of multilingual possibilities in education was not complete and impartial on the level of the European Union and for a selected jurisdiction – namely, Poland. Current regional legal regulations fail to equitably address the needs of RBSs, and national-based attention eliminated the question of newcomers’ rights in education. Moreover, as highlighted for current policy-making in the European Union, there is a gap between current legal intention and political views produced by EU institutions – for example, The Commission Action Plan on the Integration of Third-Country Nationals.

Inference By Pretexts in Contemporary Industries: 2) Inference in Opening the Excuses

It is commonly recognized that a variety of sectors benefit people and successfully advance their interests, which ultimately leads to the welfare of mankind as a whole. This study shows how modern industrial regulations in the Kingdom of Saudi Arabia relate to putting an end to pretexts as well as opening solutions with laws. The study demonstrated the Saudi regulator's consideration of opening the methods in current industry regulations after proposing the rule of opening the methods and the term contemporary industries. The study produced results, the most notable of which is the broad coverage of Sharia regulations to control every aspect of life in a way that accomplishes the interests of all people and prevents damage from them. This is done to achieve the goal of stopping evils and preventing damage through opening interests that result in reducing harm to people, endangering the security and stability of societies, harming people, destroying their social and welfare interests, and other matters of beliefs and worldly life. The goal of this study, which employed analytical, inductive, and descriptive methodologies, was to characterize the concept of pretext-based reasoning. Additionally, broadening the definition of sectors that benefit society makes the legislative restrictions on such industries more understandable.

The human and financial costs of conservation for local communities living around the Greater Serengeti Ecosystem, Tanzania

Protected areas have long been recognized globally as an important strategy for conserving biodiversity. However, the establishment of protected areas has often adversely impacted local livelihoods, particularly where people and their livelihoods are exposed to wildlife threats. Understanding the magnitude and the types of human and livelihood losses to wildlife can help to reduce the losses in the future. Here we collected and analysed a large and comprehensive historical data sets on crop damage, livestock depredation, and human attacks over eight years from January 2015 to October 2022 from Serengeti District and Ngorongoro Conservation Area to understand human and livelihood losses to wildlife in the Greater Serengeti Ecosystem (GSE). The data were government records of loss and compensation. Additionally, we performed individual interviews on what communities lose to wildlife in the area. We found that wildlife causes serious annual losses of crops (value estimated at USD 489,000) and livestock (USD 17,600). On average 22 people from villages beside or within the protected areas were injured each year and eight people were killed, usually by elephants. Compensation paid by the government to local communities only covered <20% of their total financial losses, and was also very little for the injury or loss of human life. Given our estimates are only for two administrative areas i.e. Serengeti District and Ngorongoro Conservation Area, the figure will be much higher if we include all districts around the GSE. These findings contribute to the broader conservation science field and the global discourse on human-wildlife conflict and coexistence. Protected area authorities should: a. take greater responsibility for protecting local communities and their assets from wildlife attacks, and b. assist the local communities with implementing deterrence and in establishing problematic animal prevention units in hotspot areas. In particular, we recommend that the Tanzanian Government should review the current compensation regulations to reflect the actual loss.

Assessment of mycotoxin contamination in cereal-based baby foods destined for infant consumption in Brazil

The presence of mycotoxins in cereal-based baby foods is undesirable, especially because infants are considered more vulnerable to toxin exposure than adults. In this context, this study evaluated the occurrence of multiple mycotoxins in 60 samples of cereal-based baby foods from Brazil and assessed the risk of the consumption of these products by children. Aflatoxins B1 and B2 (AFB1, AFB2), deoxynivalenol (DON), 3-acetyl deoxynivalenol (3-ADON), 15-acetyl deoxynivalenol (15-ADON) and zearalenone (ZEN) were evaluated by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The results revealed that 98.3% of the samples were contaminated by at least one mycotoxin, with 80% of them demonstrating co-contamination. DON was detected in 80% of the samples, followed by 15-ADON (71.7%), 3-ADON (65%), ZEN (56.7%) and AFB1 (5%), with none of the samples contaminated by AFB2. The maximum concentrations found were 75.6 μg/kg for DON, 18.9 μg/kg for ZEN, 9.6 μg/kg for 15-ADON, 3.5 μg/kg for AFB1 and 2.8 μg/kg for 3-ADON. The occurrence of AFB1 was low, however, some products exceeded the limits established by the current regulations. Although the estimated daily intake (EDI) of DON, 3-ADON, 15-ADON and ZEN were below the safety values currently established, the margin of exposure (MOE) values for AFB1 indicate a concern for public health.

Establishment Of The Asset Confiscation Law To Minimize Corruption In Indonesia

This research is qualitative research with a descriptive approach, namely describing a number of things that are closely related to confiscation of assets in criminal law, criminal acts of corruption, and other things. The data used in this research is secondary data in the form of the Criminal Code, Civil Code, statutory regulations, the official website of the House of Representatives, other credible websites, and so on. The researchers analyzed the data using grammatical and systematic legal analysis techniques, namely interpreting every word in the legislation and connecting it with other secondary data or other related legislation. The result in this article show there are three major urgencies for the presence of the Law on Asset Confiscation in Indonesia, namely to provide instruments that are stricter than the current regulations because in the Criminal Code, asset confiscation is only an additional crime and not the main crime, providing a deterrent effect for corruptors and potential corruptors, and of course minimizing corruption cases in Indonesia. Under existing legal structures, state losses resulting from criminal acts of corruption cannot be recovered. Recovering state losses takes years and may not even be returned at all. What is meant to provide a deterrent effect in this research is to impoverish corruptors, change the nomenclature of words whose nature is emphasized from facultative to imperative, and change its status not only to become an additional crime, but also to become a principal crime. On this basis, researchers are of the opinion that the presence of asset confiscation laws in Indonesia can be effective in minimizing the occurrence of corruption in Indonesia.

The Cellular Response Is Determined by a Combination of Different ELF-EMF Exposure Parameters: A Scope Review

Since the establishment of regulations for exposure to extremely low-frequency (0–300) Hz electromagnetic fields, scientific opinion has prioritised the hypothesis that the most important parameter determining cellular behaviour has been intensity, ignoring the other exposure parameters (frequency, time, mode, waveform). This has been reflected in the methodologies of the in vitro articles published and the reviews in which they are included. A scope review was carried out, grouping a total of 79 articles that met the proposed inclusion criteria and studying the effects of the different experiments on viability, proliferation, apoptosis, oxidative stress and the cell cycle. These results have been divided and classified by frequency, intensity, exposure time and exposure mode (continuous/intermittent). The results obtained for each of the processes according to the exposure parameter used are shown graphically to highlight the importance of a good methodology in experimental development and the search for mechanisms of action that explain the experimental results, considering not only the criterion of intensity. The consequence of this is a more than necessary revision of current exposure protection regulations for the general population based on the reductionist criterion of intensity.

Second Life of Used Lithium-Ion Batteries from Electric Vehicles in the USA

This article focuses on the reuse and recycling of end-of-life (EOL) lithium-ion batteries (LIB) in the USA in the context of the rapidly growing electric vehicle (EV) market. Due to the recent increase in the enactment of both current and pending regulations concerning EV battery recycling, this work focuses on the recycling aspect for lithium-ion batteries rather than emphasizing the reuse of EOL batteries (although these practices have value and utility). A comparative analysis of various recycling methods is presented, including hydrometallurgy, pyrometallurgy, direct recycling, and froth flotation. The efficiency and commercial viability of these individual methods are highlighted. This article also emphasizes the practices and capabilities of leading companies, noting their current superior annual processing capacities. The transportation complexities of lithium-ion batteries are also discussed, noting that they are classified as hazardous materials and that stringent safety standards are needed for their handling. The study underscores the importance of recycling in mitigating environmental risks associated with EOL of LIBs and facilitates comparisons among the diverse recycling processes and capacities among key players in the industry.

Ship Operation Analysis and Optimization via Mobile Application

This paper is devoted to studying the structure and prospects of ship operations analysis and optimization via mobile applications, focusing on integrating multiple existing onboard monitoring and control systems. The main parts of the paper describe the current state of the most essential components of future overall shipping and ship design optimization using onboard and cloud-based monitoring systems from a dual transition point of view. Special attention is paid to the ship’s and its equipment’s efficiency improvements, fuel consumption and emissions reduction, cost-effectiveness enhancement, metrological accuracy, and compliance with current regulations. Timely development and deployment of the proposed onboard monitoring systems, in combination with up-to-date mobile applications and cloud computing, should play a crucial role in promoting sustainable and environmentally friendly shipping practices, improving operational performance, and reducing risks to human life at sea and the environmental impact of shipping. Another objective of this research is to review the current state of infrastructure used for fuel control, focusing on measurement systems and related analytics using appropriate mobile applications. The recommendations for integrating new and adopting existing monitoring systems and equipment for promising alternative fuels must be given to meet current regulations and provide required safety levels and measurement quality.

Use and Abuse of Social Media as a Punitive Remedy in Light of Criminal Law: A Tool or a Court? Analysis of the Chilean Regulation

Over the last few years, Chile’s judicial system has witnessed a rise in criminal assumptions generated through social networks, under its hypotheses of funas, doxing, flagging or, in general, the exposure of the personal data of an individual, whether motivated by the performance of conduct of criminal relevance or simply of dubious morality or social appropriateness. Although these conducts originated as a form of digital social empowerment, they have turned into a criminal matter on their own right, posing a series of issues regarding the correct application of the law and casting doubt on the appropriate legal mechanisms to handle these types of accusations, as cases involving these kinds of conducts have been resolved both on a criminal and constitutional level. Thus, the purpose of this article is to determine whether the current Chilean national regulation provides sufficient tools that, with a reasonable interpretation, allow it to correctly handle these sorts of cases. Moreover, this article aims to, through a comprehensive analysis of Germany’s current legislation, determine whether Chile requires a new all-encompassing regulatory approach to these hypotheses similar to the German solution, or if the current rules provide a proper solution to the problem of public personal data exposure on social media as a dangerous behaviour for the person whose data is being exposed.

Exploring Practitioners’ Views on Product Placement: What can Taiwan Learn from the West

To improve Taiwan’s media production quality, especially in placement marketing practices, this study explores Western practices and regulations to find what Taiwan can learn from the West. The study first gathered, reviewed, and analyzed past placement marketing studies and literature from Europe and the United States, then conducted in-depth interviews with a scholar who reviews placement marketing violation cases for Taiwan’s competent authority (NCC) and American media professionals who had first-hand experience with placement marketing practices. The interviews revealed how Americans had executed the placements at various levels during the entire production process, from preproduction to postproduction; it also informed that their placement practice is natural and subtle creatively and how Americans combine product placements in the content with on-screen graphic overlays to gather consumer data. The study also exposed a curiously interesting product placement phenomenon with Taiwanese news media and how they get away with the current laws and regulations.   Received: 6 January 2024 / Accepted: 19 April 2024 / Published: 5 May 2024

Ten-Year Response of Riparian-Associated Songbirds to Implementation of Streamside Management Zones in Watershed-Scale Harvests in the Appalachian Mountains

Abstract Streamside management zones (SMZs) are regulated components of actively managed forests in the eastern United States, but width and overstory retention requirements vary widely among states. Within watershed-scale harvests, we evaluated the relative abundances of three riparian-associated songbirds (Acadian flycatcher, Empidonax virescens; blue-headed vireo, Vireo solitarius; and Louisiana waterthrush, Parkesia motacilla) near Appalachian headwater streams receiving three SMZ treatments representative of a range of current state SMZ regulations in the eastern United States. Prior to harvest, all species were relatively abundant near all stream types, including ephemerals. Abundances of all species were largely similar among SMZ treatments at 3 years and 10 years postharvest and were higher along streams with greater residual canopy cover within 100 m. Forested SMZs as prescribed by current regulations can sustain these species in managed forests up to 10 years postharvest, but abundance appears to be driven largely by canopy cover retention in adjacent stands. Managing habitat for riparian-associated songbirds in harvested watersheds will require expanding the extent of focus beyond the local stream corridor to include consideration of silvicultural systems that retain greater canopy cover in surrounding forests. Where conservation of riparian-associated songbirds is a management objective, SMZ protection should be extended to all streams. Study Implications. The results of this study suggest that forested streamside management zones (SMZs) mandated by contemporary best management practices (BMPs) in Kentucky and other eastern US states can sustain similar abundances of three riparian-associated songbirds in managed watersheds up to 10 years after harvest. Overstory retention in SMZs along perennial and intermittent streams is common across the eastern United States, but state BMPs rarely require retention along ephemeral streams. Target songbird species occupied forests along all stream types prior to harvest, and their postharvest abundances were positively associated with canopy retention within 100 m of streams. If long-term occupancy of managed stands by riparian-associated songbirds is an objective, we recommend using SMZs around all streams, including ephemerals, and implementing at least moderate-retention silvicultural systems in areas within 100 m of streams.

Images of Corporeality in Law: The Experience of the BRICS Countries

This article presents the authors’ approaches to understanding the concept of corporeality in its normative dimension. The purpose of the study is to conceptualize the images of human corporeality that exist in the system of legal regulation. Based on the idea that the research category is a representation of certain characteristics of the human body, the authors substantiate the possibility of using institutional and functional-activity approaches to analyzing human corporeality. Both of these approaches are based on distinct foundations, which include social institutions, fields of activity and functional purposes of the human body. The common basis for the two approaches lies in the biosocial component, which is considered one of the defining characteristics of an image of corporeality. Depending on the approach used, the authors propose three classifications of images of corporeality: private and public, collective and individual and normal and abnormal. Regulatory practices that are aimed at consolidating these images of corporeality are analyzed within the framework of the current legal regulations in the BRICS countries. The authors conclude by noting that corporeality is a biosocial category that serves as the basis for legal subjectivity, while gaps in existing images of corporeality are the basis for its normalization.
