Authors: Liu Qi , Jiang Jianzhong , Dong Hongshan 
Published: January 2024

Abstract
In response to the difficulty of waste heat removal in underground confined spaces, a calculation model of evaporatively condensed cooling systems in underground projects has been established in this paper. Through calculation and analysis, the results show that among various influencing factors, the change in condensing temperature has the greatest influence on the cooling air volume. Increasing the condensing temperature can significantly reduce the air volume and air duct section, and there exists an optimal condensing temperature range that will reduce the total energy consumption and air volume of the system. On this basis, a calculation App for the optimal condensing temperature of the cooling system under different working conditions was designed, and the cooling system of a practical project was optimized, greatly reducing the difficulty and cost of air duct construction.

Published: January 2024

Abstract
In this paper, the operating principle and control scheme in the CCM mode of the front-end totem pole PFC are analyzed. Based on the operating characteristics of the circuit topology, a PR controller is used to control the input current. When the grid voltage contains harmonic signals, a low harmonic compensator is cascaded in the original PR controller to reduce the impact of harmonics in the grid voltage on the control effect. Then input current distortion is analyzed when the AC input voltage crosses zero point, and the corresponding optimization method is proposed. Finally, different experiments are carried out to verify the effectiveness of the proposed method.

Published: January 2024

Abstract
Solar thermal power generation is an important way to solve the future power demand, and some countries have entered the commercial application stage. According to the heat source temperatures provided by different solar thermal collector systems, different thermodynamic cycle modes of power generation systems were proposed so that the appropriate thermal cycle modes and working mediums at different heat source temperatures were obtained. The results show that, under a low-temperature heat source, in an organic Rankine cycle with R600 as the working medium, the cycle efficiency is 13.40% when the temperature of the turbine inlet is 100°C and the pressure is 1.5 MPa; the cycle thermal efficiency is 12.00% when the temperature of turbine inlet is 90°C. Under the conditions of medium temperature heat source, in the Rankine cycle with regenerative heat and R141b as a working medium, the efficiency is about 26.59% when the temperature of the turbine inlet is 220°C and the pressure is 3.0 MPa. Under the conditions of a high-temperature heat source, in the reheat extraction steam Rankine cycle, the theoretical cycle efficiency can reach 34.32% when the temperature of the turbine inlet is 380°C, the pressure is 8 MPa, and the condensation temperature is 41.5°C. The studies can provide a fundamental basis for the design of solar thermal power generation systems with different heat source conditions.
Experiment and simulation study on the characteristics of pressure swirl nozzle flash spray under the influence of superheat
Authors: Zheng Lei , Xu Haizhou , Fu Hao , Chen Hua , Cheng Wenlong 
Published: January 2024

Abstract
The good atomization performance of the pressure swirl nozzle makes it widely used in the fuel injection device of the internal combustion engine. Flash spray caused by fuel inlet superheat can affect spray and combustion characteristics. In this paper, a spray parameter measurement system is set up, combined with phase Doppler particle analysis (PDPA) technology to research the effect of superheat on spray velocity and droplet diameter distribution. To improve the safety of the experiment, Methyl Nonafluorobutyl Ether (HFE7100) with a boiling point of 61°C was used as the spray fluid. The cavitation model and VOF model are used to simulate the pressure swirl nozzle flash spray. The results show that when the temperature changes from 40°C to 60°C, the velocity of spray droplets increases and the particle size decreases under the action of weak evaporation; When the temperature changes from 60°C to 70°C, the evaporation mode is dominated by flash, making the droplet velocity at the spray center greatly increase and the velocity distribution change from saddle-shaped distribution to unimodal distribution. The droplet diameter increases, which may be due to the expansion of the droplet caused by the formation of bubbles inside the droplet under the action of flash.
Integrated technology for layered sand control and layered water injection
Authors: Wang Cong 
Published: January 2024

Abstract
In order to solve the problem of water injection string failure caused by pipe creep and sand production in layered water injection wells, an integrated technology of layered sand control and layered water injection has been developed. A suspended large-radiuslayered mechanical sand control pipe column has been designed, providing sufficient design and usage space for the layered water injection pipe column. Developing a new type of anti-creep sealed packer can effectively improve the anti-creep performance of the water injection string and extend the validity period of the string. This technology integrates and optimizes layered water injection and sand control technology, large channel backwashing technology, integrated testing and allocation technology, and anti-creep technology of the pipe string. While effectively solving sand production in offshore water injection wells, it extends the service life of the water injection pipe string and reduces operating costs. Since 2018, this technology has been implemented in over 200 wells in Chengdao Oilfield, with a maximum of 6 layers for prevention and injection, a maximum well inclination of 48.8°, and a construction success rate of over 90%. It has achieved very good development results and economic benefits.

Published: January 2024

Abstract
The ultra-shallow heavy oil reservoir in Chunfeng Oilfield has become an important position in increasing reserves and production. Vertical wells have low production and poor benefits. The development engineering technology of horizontal wells faces many technical problems. Aiming at the drilling problems of ultra-shallow heavy oil horizontal wells, research and application have been carried out from the aspects of drilling engineering optimization design and shallow soft formation trajectory control. Shallow heavy oil cementing and completion and key drilling and completion technologies suitable for the efficient development of ultra-shallow heavy oil in the Neogene of Junggar Basin have been formed. The field application results show that the technology has well supported the development of ultra-shallow heavy oil reservoirs and has accumulated many construction records, such as the shallowest vertical depth, the largest vertical ratio, and the shortest drilling and completion period. The new production capacity of 50 thousand tons has strongly supported the benefit and production increase of Shengli exploration area in the Junggar Basin.

Abstract
With the rise in microbial resistance to traditional antibiotics and disinfectants, there is a pressing need for the development of novel and effective antibacterial agents. Two major approaches being adopted worldwide to overcome antimicrobial resistance are the use of plant leaf extracts and metallic nanoparticles (NPs). However, there are no reports on the antibacterial potential of NPs coated with plant extracts, which may lead to novel ways of treating infections. This study presents an innovative approach to engineer antibacterial NPs by leveraging the inherent antibacterial properties of zinc oxide NPs (ZnO NPs) in combination with Azadirachta indica (AI) leaf extract, resulting in enhanced antibacterial efficacy. ZnO NPs were synthesised by the precipitation method and subsequently coated with AI leaf extract to produce ZnO-AI nanocore–shell structures. The structural and morphological characteristics of the bare and leaf extract coated ZnO NPs were analysed by x-ray diffraction and field emission scanning electron microscopy, respectively. The presence of an AI leaf extract coating on ZnO NPs and subsequent formation of ZnO-AI nanocore–shell structures was verified through Fourier transform infrared spectroscopy and photoluminescence techniques. The antibacterial efficacy of both ZnO NPs and ZnO-AI nanocore–shell particles was evaluated against methicillin-resistant Staphylococcus aureus using a zone of inhibition assay. The results showed an NP concentration-dependent increase in the diameter of the inhibition zone, with ZnO-AI nanocore–shell particles exhibiting superior antibacterial properties, owing to the combined effect of ZnO NPs and the poly phenols present in AI leaf extract. These findings suggest that ZnO-AI nanocore–shell structures hold promise for the development of novel antibacterial creams and hydrogels for various biomedical applications.
Synthesis of Fe3O4 core/MIL-100(Fe) shell nanocomposites for tumor chemo-ferroptosis combination therapy and MR imaging

Published: January 2024

Abstract
The application of both chemotherapy and ferrotherapy together has shown great potential in increasing the effectiveness of cancer treatment. To achieve such a combination, we herein have synthesized Fe3O4 core/MIL-100(Fe) shell nanocomposites (FM) that can be used for tumor chemo-ferroptosis combination therapy. In these nanocomposites, the anticancer drug 10-hydroxycamptothecin (HCPT) and iron ions could be co-delivered into tumors. On one hand, the released HCPT molecules can enter the cell nucleus and bind with DNA, resulting in induction of tumor cell apoptosis. On the other hand, the iron ions could react with H2O2 leading to the production of ROS through the Fenton reaction, thereby triggering tumor cell ferroptosis. Consequently, a superior antitumor effect was achieved through the combination of the apoptosis and ferroptosis. Additionally, the Fe3O4 core endowed FM with high performance for magnetic resonance imaging, which further provided novel avenues for imaging guidance therapy. Therefore, we anticipate that application of these nanocomposites could have great potential in the field of tumor therapy.
Interaction vs inhomogeneity in a periodic TASEP
Authors: Mina Beatrice , Paninforni Alex , Pelizzola Alessandro , Pretti Marco 
Published: January 2024

Abstract
We study the non-equilibrium steady states in a totally asymmetric simple exclusion process with periodic boundary conditions, also incorporating (i) an extra (nearest-neighbour) repulsive interaction and (ii) hopping rates characterized by a smooth spatial inhomogeneity. We make use of a generalized mean-field approach (at the level of nearest-neighbour pair clusters), in combination with kinetic Monte Carlo simulations. It turns out that the so-called shock phase can exhibit a lot of qualitatively different subphases, including multiple-shock phases, and a minimal-current shock phase. We argue that the resulting, considerably rich phase diagram should be relatively insensitive to minor details of either interaction or spatial inhomogeneity. As a consequence, we also expect that our results help elucidate the nature of shock subphases detected in previous studies.

Published: January 2024

Abstract
Room-temperature ferromagnetism (RTFM) has been achieved in Mn-doped InSb nanowires (NWs) through experiment. However, the underlying cause of RTFM remains unclear. In this paper, using first-principles calculations, the distribution of Mn ions and magnetic properties of Mn-doped wurtzite and zinc blend InSb NWs have been investigated. Our results indicate that wurtzite (In,Mn)Sb NWs can exhibit superior ferromagnetic behavior compared to zinc blend (In,Mn)Sb NWs. The distribution of Mn ions and magnetic properties in the (In,Mn)Sb NWs is influenced by their size, surface passivation and crystal structure. Furthermore, the ferromagnetic coupling is short-range in passivated (In,Mn)Sb NWs, and as the size of the NW decreases, the Mn-3d level becomes a deep acceptor in the band gap, resulting in an enhancement of ferromagnetism.
London, 1984
Authors: Brooke Stephen 
Published: January 2024

Abstract
Margaret Thatcher remarked that there was ‘no alternative’ to her reforming agenda in the 1980s. But London in that decade put the lie to that remark: there was an alternative, one that lay in the city itself. London, 1984: Conflict and Change in the Radical City is a history of a city poised between two futures: one shaped by the neoliberalism of the Conservative government, one shaped by a resurgent social democracy out of County Hall in the form of a Labour Greater London Council and the efforts of many community organizations, groups, and individuals on the ground. The book explores that conflict through an exploration of one year—1984—and the stories of a series of moments, organizations, and artefacts. These include a protest on the Thames against the development of the Docklands, a raid on a gay bookshop, racial violence on an East End estate, efforts to make the city more equal for racial minorities, women, and gay and lesbian people, a major anti-apartheid demonstration, and tensions between the police and the Black community that led to an explosion of violence. London, 1984 is a focused account of a critical year in the history of a city.
Introduction
Authors: Brooke Stephen 
Published: January 2024

Abstract
This chapter introduces the book’s content and themes by examining how two rival political cultures came into conflict in 1980s London: Thatcherite neoliberalism and a new form of social democracy in the form of the Greater London Council. Both offered different visions of the city’s development. The chapter surveys the current literature on the 1980s, on Thatcherism, and on the politics of late twentieth-century London. It outlines the approach of the book, which concentrates on one particular year, 1984, as a way of exploring how political change in a variety of forms was experienced at different registers in the city.
Anti-Racist Year
Authors: Brooke Stephen 
Published: January 2024

Abstract
1984 was declared Anti-Racist Year by the GLC. This chapter explores the work that the GLC and community organizations did around questions of race and ethnicity in the 1980s, culminating in Anti-Racist Year, 1984. It examines not only the work of the GLC and its Ethnic Minorities Committee but also the work of community organizations at the grass-roots level. The chapter discusses the attempt to nurture popular support for anti-racist initiatives and explores how this initiative not only pushed forward the frontier of equality but also created an image of a multiracial London.
Capital City? People’s Armadas, Pop, and Planning
Authors: Brooke Stephen 
Published: January 2024

Abstract
This chapter examines three events in 1984—the People’s Armada, the ‘Jobs for a Change’ concert, and the purchase of the Coin Street site by a community organization. This is an exploration of alternatives to the neoliberal economic agenda of the Thatcherite government, which might be seen in the attempt to redevelop the Docklands. The chapter looks at different forms of community-based alternatives and protest, and reflects upon how popular culture, in particular popular music, was used to challenge the government on issues such as unemployment. It also considers how the GLC itself developed an alternative economic strategy that gave particular attention to questions of racial and gender equality.
A City for Women?
Authors: Brooke Stephen 
Published: January 2024

Abstract
This chapter tells two stories. The first is of the publication of Making Space in 1984 by the feminist design collective Matrix. That work highlighted the challenges faced by women in negotiating a hostile city. It offered, by contrast, a feminist view of the city, which could be seen in the way it designed buildings and worked with clients. The second story is about a larger feminist challenge to urban life pursued by the GLC Women’s Committee, the first major state group to tackled questions of gender equality. Both stories underline the problems of sexism and gender equality in the late twentieth-century city and foreground feminist attempts to make a city for women.
Westminster and Broadwater Farm
Authors: Brooke Stephen 
Published: January 2024

Abstract
At the end of 1984, parliament passed the Police and Criminal Evidence Act, which formalized controversial powers of stop-and-search for the Metropolitan Police. These powers had shaped everyday life for Black communities in London, sparking, for example, the 1981 Brixton disorders. This chapter looks at the policing of Black communities from two perspectives. On the one hand, it considers the history of stop-and-search as a police tactic. On the other, it looks at the impact of that policing on Black communities, focusing in particular upon the Broadwater Farm Estate in Tottenham. There were attempts by Black people on that estate to resist such policing. On a broader level, there were also calls to make the police more democratically accountable to communities in the 1980s. This chapter thus brings up fundamental and continuing questions about the relationship between policing and race.
Conclusion

Published: January 2024

Abstract
This chapter concludes the book by considering the existing traces of 1980s London in the present day. The chapter reviews the arguments of the book and explores the legacy of 1984 to contemporary London, mapping the continuities and disjunctures between the two periods. The considers the impact of neoliberalism and gentrification upon the city, placing recent events such as the 2017 Grenfell tragedy in a wider historical context. In particular, the chapter discusses the persistence of inequality and the problems of democratic accountability.

Abstract
Biotic and abiotic stresses negatively affect the yield and overall plant developmental process, thus causing substantial losses in global sweet potato production. To cope with stresses, sweet potato has evolved numerous strategies to tackle ever-changing surroundings and biological and environmental conditions. The invention of modern sequencing technology and the latest data processing and analysis instruments has paved the way to integrate biological information from different approaches and helps to understand plant system biology more precisely. The advancement in omics technologies has accumulated and provided a great source of information at all levels (genome, transcript, protein, and metabolite) under stressful conditions. These latest molecular tools facilitate us to understand better the plant’s responses to stress signaling and help to process/integrate the biological information encoded within the biological system of plants. This review briefly addresses utilizing the latest omics strategies for deciphering the adaptive mechanisms for sweet potatoes’ biotic and abiotic stress tolerance via functional genomics, transcriptomics, proteomics, and metabolomics. This information also provides a powerful reference to understand the complex, well-coordinated stress signaling genetic regulatory networks and better comprehend the plant phenotypic responses at the cellular/molecular level under various environmental stimuli, thus accelerating the design of stress-resilient sweet potato via the latest genetic engineering approaches.

Abstract
Artificially enhancing photosynthesis is critical for improving crop yields and fruit qualities. Nanomaterials have demonstrated great potential to enhance photosynthetic efficiency; however, the mechanisms underlying their effects are poorly understood. This study revealed that the electron transfer pathway participated in nitrogen-doped carbon dots (N-CDs)-induced photosynthetic efficiency enhancement (24.29%), resulting in the improvements of apple fruit qualities (soluble sugar content: 11.43%) in the orchard. We also found that N-CDs alleviated mterf5 mutant-modulated photosystem II (PSII) defects, but not psa3 mutant-modulated photosystem I (PSI) defects, suggesting that the N-CDs-targeting sites were located between PSII and PSI. Measurements of chlorophyll fluorescence parameters suggested that plastoquinone (PQ), the mobile electron carrier in the photosynthesis electron transfer chain (PETC), was the photosynthesis component that N-CDs targeted. In vitro experiments demonstrated that plastoquinone-9 (PQ-9) could accept electrons from light-excited N-CDs to produce the reduced plastoquinone 9 (PQH2-9). These findings suggested that N-CDs, as electron donors, offer a PQ-9-involved complement of PETC to improve photosynthesis and thereby fruit quality. Our study uncovered a mechanism by which nanomaterials enhanced plant photosynthesis and provided some insights that will be useful in the design of efficient nanomaterials for agricultural/horticultural applications.
