Deinococcus lineage and Rad52 family-related protein DR0041 is involved in DNA protection and compaction

DR0041 ORF encodes an uncharacterized Deinococcus lineage protein. We earlier reported presence of DR0041 protein in DNA repair complexes of Ssb and RecA in Deinococcus radiodurans. Here, we systematically examined the role of DR0041 in DNA metabolism using various experimental methodologies including electrophoretic mobility assays, nuclease assays, strand exchange assays and transmission electron microscopy. Interaction between DR0041 and the C-terminal acidic tail of Ssb was assessed through co-expression and in vivo cross-linking studies. A knockout mutant was constructed to understand importance of DR0041 ORF for various physiological processes. Results highlight binding of DR0041 protein to single-stranded and double-stranded DNA, interaction with Ssb-coated single-stranded DNA without interference with RecA-mediated strand exchange, protection of DNA from exonucleases, and compaction of high molecular weight DNA molecules into tightly condensed forms. Bridging and compaction of sheared DNA by DR0041 protein might have implications in the preservation of damaged DNA templates to maintain genome integrity upon exposure to gamma irradiation. Our results suggest that DR0041 protein is dispensable for growth under standard growth conditions and following gamma irradiation but contributes to protection of DNA during transformation. We discuss the role of DR0041 protein from the perspective of protection of broken DNA templates and functional redundancy.

The concept of personal data protection culture from European Union documents: a “Brussels effect” in Latin America?

This article aims to analyse, based on documentary sources and data collected through extensive field research, the potential cultural influence of EU (European Union) standards for protecting personal data in Latin American countries, which have data protection authorities and specific laws on the subject. The text has two sections, with an introduction and a conclusion. The introduction presents the subject, indicating the sources that lead up to the text analysis and conclusions. In the first section, the article deals with the EU’s data protection model from its fundamentalist legal perspective. The second section deals with constructing the personal data protection culture concept and how extensive EU documents research can help infer it. The conclusion indicates that the EU’s data protection perspective – as a fundamental right and public policy – can potentially influence several Latin American countries. Also, it concludes that there is an evident difficulty in culturally measuring greater or lesser effectiveness in protecting personal data based on the documents. Despite this dilemma, the EU documentation points to some qualitative suggestions that deserve to be incorporated into the analysis of cultures of personal data protection, focusing on Latin American countries.

Current status and perspectives of personal data protection under the conditions of marital state

The aggression of russia has created numerous problems in terms of legal and organizational protection of personal data. Therefore, this article analyzes the current state and prospects of personal data protection during a state of war. The author examines the changes to legislation in this field caused by russia’s full-scale invasion and analyzes the state of cybersecurity legislation in Ukraine as part of personal data protection.Emphasis is placed on the fact that effective protection of personal data is impossible without ensuring cybersecurity. The experience of Estonia as a leading European country in this field is highlighted. The main directions of Estonia’s data protection policy are indicated.The analysis of legislation and law enforcement practices highlights a number of issues, such as the absence of a plan for cyber attacks and the vulnerability of devices used for photo and video documentation at checkpoints. It is expressed that these shortcomings need to be addressed through the adoption of a new law on personal data protection.Regarding the prospects of personal data protection in a state of war, the article argues that measures for safeguarding personal data should be taken by both private individuals and state institutions. Private individuals should employ measures such as using reliable software and data encryption. State institutions should implement the following measures: in the event of a threat of occupation of a specific locality, the authorities and their officials should destroy documents and other physical media containing personal data of Ukrainian citizens.The overall conclusion is that the protection of personal data is a constant challenge, and the development of new technologies requires continual updating of security measures. Users and organizations must be knowledgeable and cautious in the processing and transmission of personal data, while legislation and standards need to constantly adapt to changes in the digital environment and the military-political sphere.

Tracking Deviceson Collateral Vehiclesby Financial Institutions Invadescustomer Privacyaccording To Privacy Protection Law

Financial institutions expect financing to be returned on time and adherethe terms of the agreement. Financial institutions profit from the ability to handle non-performing loans (NPL). The lower the level of NPL, the lower the risk and the higher the profit made by the financial institution. One way to mitigate risk is the capacity to take over the collateral for financing. One of the collaterals for financing is in the form of a vehicle. This vehicle is guaranteed by Fiduciarysecurity. If consumer default occurs, financial institutions can seize the collateral and use it to pay off the loan. Financial institutions employ a variety of strategies to ensure that collateral is quickly located in the event of a default. One method is to use technology to install a tracking device. This study scrutinizes the use of tracking devices by financial institutions from the perspective of consumer privacy protection. This normative legal research concludes that collaterals with Fiduciarysecurity are property of financial institutions prior to settlement. However, the installation of tracking devices on collateral vehicles might invade customer privacy. The customer has the option to objectthe installation of the device on the vehicle

Simulation Analysis of Land-Use Spatial Conflict in a Geopark Based on the GMOP–Markov–PLUS Model: A Case Study of Yimengshan Geopark, China

The foundation for accurately understanding regional land-use structures and pursuing the coordination of human–land relations is the scientific identification and simulation of temporal and spatial evolution patterns of land-use spatial conflict (LUSC). Based on the production–living–ecological space (PLES) perspective, a land-use spatial conflict identification and intensity diagnosis model (LUCSII) was constructed using a landscape ecology index. The methods of geographic information system (GIS), spatial autocorrelation analysis, and mathematical statistics were used to achieve the spatial pattern of LUSC over the last 20 years, and the GMOP–Markov–PLUS model was used to simulate the evolution of LUSC in the future under various scenarios. The results indicated that our established LUCSII could accurately identify potential land-use spatial conflict areas in geoparks. The GMOP–Markov–PLUS model constructed had also scientifically predicted the future land-use patterns under different scenarios, successfully demonstrating the changing process of spatial conflict pattern evolution. The research proposed three different plans for the long-term land use of YG, including ecological protection, economic development, and long-term development perspectives. Finally, the research further emphasized the importance for sustainable development of geoparks. More attention should be paid to the optimal allocation of land-use structure and the coordinated development of human–land relationships.

The second is to implement green financial regulation and improve the driving force of green policy and market integration. The research results show that the comprehensive measurement score of green finance development level in Beijing, Tianjin and Hebei region shows a steady increase between 2016 and 2020, among which the comprehensive measurement score of green finance development level in Beijing is as high as 72.13 in 2020, an increase of 17.32%. It provides theoretical guidance for the improvement of green financial public policies in Beijing, Tianjin and Hebei regions.

Bisphenol A (BPA) Content in Food and Beverage Plastic Packaging Perspective of Food Law and Consumer Protection

The packaging sector is an important industry. Packaging is used as a material to protect goods from external contamination. There are various kinds of packaging, one of which is often used is plastic packaging. In plastic packaging there is one of the BPA materials used in the plastic manufacturing process. This BPA content has the potential to be released and mixed with packaged food and drinks. While BPA is a content that can cause various diseases such as cancer. This study aims to determine the content of BPA in plastic packaging seen from the Law on Food and the Law on Consumer Protection. This study uses normative legal research that is descriptive analytical with a qualitative approach to primary data, secondary data and tertiary data which includes the content and structure of positive law. It is used as a reference in reviewing legal issues that are the object of study. The results of the study show that the BPA content in plastic packaging does not meet the packaging quality standards in accordance with the Law on Food. The Law on Food states that food packaging must use materials that do not endanger health. The Law on Consumer Protection also states that one of the rights of consumers is to have security and safety in consuming goods and services. The content of BPA which can cause various diseases is clearly not in accordance with the clauses in the Consumer Protection Act.

Construct the future wetland ecological security pattern with multi-scenario simulation

The construction of wetland ecological security pattern has important guiding significance for balancing urban development and ecological restoration. In this paper, the PLUS model was used to simulate the land use change under the business as usual scenario (BAU), economic development scenario (ED) and expansionary conservation scenario (EC) in 2030. Coupled with the wetland ecological security pattern, four wetland ecological networks were constructed for vertical and horizontal comparative analysis. The optimal network was selected and ecological pinch points and obstacles were identified. The results showed that: (1) The land use change mainly occurred in the main urban area of Haikou. Under BAU and ED scenarios, the area of construction land increased greatly. Under EC scenarios, the overall ecological land in Haikou would expand, but the area of wetland showed a downward trend. (2) In 2030, the overall ecological wetland network will be improved, the number and length of corridors will increase significantly, and the network structure under EC scenario will be more stable. (3) The number and area of ecological pinch points and obstacle points under the EC scenario in 2020 and 2030 increased significantly, and this area should be regarded as a priority area for ecological protection. This study provides a new perspective for ecological protection and restoration, and provides a reference for clarifying the direction of wetland ecological restoration work and formulating urban construction and development policies.

A Study on the Impermeability of Nanodispersible Modified Bentonite Based on Colloidal Osmotic Pressure Mechanisms and the Adsorption of Harmful Substances

With the growing demands of human beings, sanitary landfill, along with the increase in landfill depth and leachate water pressure, has put forward new and higher requirements for the impermeable layer. In particular, it is required to have a certain adsorption capacity of harmful substances from the perspective of environmental protection. Hence, the impermeability of polymer bentonite–sand mixtures (PBTS) at different water pressure and the adsorption properties of polymer bentonite (PBT) on contaminants were investigated through the modification of PBT using betaine compounded with sodium polyacrylate (SPA). It was found that the composite modification of betaine and SPA could reduce the average particle size of PBT dispersed in water (reduced to 106 nm from 201 nm) and enhance the swelling properties. As the content of SPA increased, the hydraulic conductivity of PBTS system decreases and the permeability resistance improves, while the resistance to external water pressure increases. It is proposed a concept of the potential of osmotic pressure in a constrained space to explain the impermeability mechanism of PBTS. The potential of osmotic pressure obtained by linear extrapolation of the trendline of colloidal osmotic pressure versus mass content of PBT could represent the external water pressure that the PBT resist. Additionally, the PBT also has a high adsorption capacity for both organic pollutants and heavy metal ions. The adsorption rate of PBT was up to 99.36% for phenol; up to 99.9% for methylene blue; and 99.89%, 99.9%, and 95.7% for low concentrations of Pb2+, Cd2+, and Hg+, respectively. This work is expected to provide strong technical support for the future development in the field of impermeability and removal of hazardous substances (organic and heavy metals).

Large-scale sediment and phosphorus transport in the Three Gorges Reservoir based on a new reservoir operation method

Change of hydrodynamic conditions is a key factor inducing sedimentation, water eutrophication and algal blooms in the Three Gorges Reservoir (TGR). How to mitigate sedimentation and phosphorus (P) retention by improving hydrodynamic conditions in the Three Gorges Reservoir area (TGRA) is an urgent issue in the study of sediment and water environment. In this study, a Hydrodynamic-Sediment-Water quality model for the whole TGRA is proposed considering sediment and P inputs from numerous tributaries, and a new reservoir operation method namely the tide-type operation method (TTOM) is used to investigate the large-scale sediment and P transport in the TGR based on the model. Results indicate that the TTOM can reduce sedimentation and total phosphorus (TP) retention in the TGR. Compared with the actual operation method (AOM), sediment outflow and sediment export ratio (Eratio) of the TGR increased about 17.13% and 1%–3% in 2015–2017, and sedimentation decreased about 3% under the TTOM. TP retention flux and retention rate (RE) decreased about 13.77% and 2%–4%. The flow velocity (V) and sediment carrying capacity (S*) increased about 40% in the local reach. Larger daily water level fluctuation at dam site is more conducive to reducing sedimentation and TP retention in the TGR. Sediment inputs from the Yangtze River, Jialing River, Wu River and other tributaries account for 59.27%, 11.21%, 3.81% and 25.70% of the total sediment inflow during 2015–2017, and TP inputs were 65.96%, 10.01%, 17.40% and 6.63%. In the paper, an innovative method is proposed to reduce sedimentation and P retention in the TGR under the given hydrodynamic conditions and related quantitative contribution driven by the proposed method is analyzed. The work is favorable for expanding the understanding of the hydrodynamic and nutrition flux changes in the TGR, and provides a new perspective for water environment protection and reasonable operation of large reservoirs.

Experimental study on hygrothermal properties of recycled aggregate concrete

Recycled aggregate concrete has great significance from the environmental protection perspective. However, the current research findings on its hygrothermal properties are sparse. In this study, the apparent density, thermal conductivity, mass moisture content, water vapor permeability coefficient, water absorption coefficient, and liquid water diffusion coefficient of recycled aggregate concrete were determined by experimental methods. The effect of temperature and humidity on thermal conductivity was also studied. Furthermore, the fitting relations of the thermal conductivity of recycled aggregate concrete with the two variables of temperature and relative humidity were presented. The isothermal moisture absorption curve and the fitting relationship of water vapor permeability coefficient with relative humidity were also developed. The results indicate that the thermal conductivity of the eight recycled concrete specimens in the dry state at 25°C ranges from 0.994 to 1.242 W/(m·K). The thermal conductivity increases with the increase in temperature. When the temperature rises from 25°C to 35°C, the thermal conductivity of recycled aggregate concrete increases by 3.8%–13.5%. With the increase of relative humidity, the thermal conductivity of recycled aggregate concrete shows an increasing trend, followed by a steady state, and finally the increasing trend, showing a cubic function relationship between them. When the relative humidity increases from 0% to 95%, the thermal conductivity increases by about 20%. The mass moisture content and the water vapor permeability coefficient increase with relative humidity. The results of this study can provide basic information for the study on the heat and moisture transfer of recycled aggregate concrete, and enhance the database of hygrothermal properties of building materials.

Regulating the Big Data-Based Discriminatory Pricing in Platform Retailing: A Tripartite Evolutionary Game Theory Analysis

Nowadays, with the rapid development of the platform economy, Big Data-based Discriminatory Pricing (BDDP) has become a common phenomenon in which big data and algorithms are applied to excessively seize consumer surplus and thus damage the rights and interests of consumers. This work aims to explore the equilibrium strategies of the consumers, the government, and the service platform and discuss factors affecting the BDDP practice of the service platforms. This study constructs a tripartite evolutionary game model among consumers, service platforms, and the government. Two evolutionary equilibrium strategies are derived and validated using simulation. Numerical experiments are conducted using MATLAB to reveal players’ evolutionary stability strategies under various settings. The study shows that (1) the strategies of the government and the platform always influence each other, (2) a reasonable adjustment of tax rate helps regulate the platform’s behavior, and (3) the proportion of consumers who switch the platform after they realize themselves suffering BDDP is an important factor influencing platform’s strategy. This study lastly summarizes the managerial insights for dealing with the platform’s BDDP behavior and safeguarding consumers’ rights from the perspectives of macro-regulation and privacy data protection. The conclusions of this study can help promote the high-quality development of the platform economy.

Overview of the Monopoly Rights of the Social Security Administering Body (BPJS) from the Perspective of Citizens' Health Protection

The monopoly right to health protection granted to the Social Security Administration Agency (BPJS) in Law no. 24 of 2011 concerning BPJS is an attempt to organize a health insurance program effectively and efficiently. However, this monopoly right also raises several problems, first, institutional problems in the implementation of the national social security system (SJSN) and related to choosing a hospital location that is not in accordance with the wishes of BPJS participants. In this legal research, it has a normative research type with a statutory approach related to the BPJS monopoly right in health protection. The research results show that in order to ensure that the national health insurance program can run effectively, coordinated and integrated efforts are needed between the government, BPJS Health, health service providers, and the community. The government needs to increase the allocation of the health budget, ensure efficient use of funds, and find alternative sources of funding

Tool Wear and Surface Integrity of γ-TiAl Cryogenic Coolant Machining at Various Cutting Speed Levels

High-speed machining of γ-TiAl alloy is a significant challenge due to high cutting temperatures. From the perspective of environmental protection and improving tool life, appropriate cooling strategies should be adopted. Compared with dry and conventional flood cooling conditions, the feasibility of machining γ-TiAl in cryogenic LN2 cooling conditions was discussed. The cutting force, tool wear and its mechanism, and surface roughness, as well as sub-surface morphology characteristics, were studied by combining macro and micro techniques. The results revealed that the wear morphology of the rake and flank face under the three cooling media shows different degrees. The crater wear of the rake face is expanded at high speeds and then progresses into more serve flaking and notching wear. The main wear pattern on the flank face is gradually transformed from adhesive wear to diffusion and oxidation wear at high speeds in dry machining. In the LN2 condition, the diffusion of workpiece elements and cutting-edge oxidation were restrained. The wear pattern is still mainly adhesive wear. In addition, cryogenic machining shows significant advantages in reducing cutting force, suppressing heat-affected zone, improving surface quality, and inhibiting micro-lamellar deformation.

Biomechanical effects of a mandibular advancement device on the periodontal ligament: Based on different bone models

Obstructive sleep apnea syndrome (OSAS) is recurrent apnoea caused by upper airway obstruction during sleep. In severe cases, OSAS might lead to sudden death. Currently, the mandibular advancement device (MAD) is the preferred product for the treatment of mild to moderate OSAS because of its compliance, portability and low cost. However, many clinical studies have suggested that long-term use of MAD might cause occlusal changes, periodontitis, muscle soreness, and joint damage. In view of the difficulties in the measurement of relevant mechanical factors in vivo, the present work aimed to quantitatively analyze biomechanical mechanisms that might lead to these side effects through computer numerical simulations and a nonhomogeneous alveolar bone model was established to approximate the actual bony features of the jaw in the simulations model. First, a 3D digital model of the teeth, periodontal ligament(PDL), and alveolar bone was created on the basis of computed tomography images and assembled with a 3D model of the MAD. A nonhomogeneous alveolar bone model was created based on computed tomographic images, and the stresses acting on the PDL were computed using the finite element method. The results showed that the nonhomogeneous model could more realistically reflect the mechanical properties of the alveolar bone and obtain the true stresses compared with the homogeneous model, which underestimated the adverse effects of PDL therapy. The numerical simulations in this paper can help doctors make more accurate judgements about MAD treatment from an oral health protection perspective.
