Research of productivity and interlayer interference mechanism of multilayer co-production in reservoirs with multi-pressure systems

Abstract Due to the differences of physical and fluid properties in vertical oil layers, the interlayer contradictions are prominent and affect the reservoir utilization degree seriously. Therefore, the coordination between reasonable bottom-hole flow pressure and optimal production, as well as the reduction of interlayer interference are the primary concerns during the co-production of multi-layer oil reservoirs. Based on the reservoir engineering and fluid mechanics in porous media theory, this work adopt the comprehensive pressure system and consider the interlayer interference to establish a multi-branch horizontal well productivity model and interlayer interference mathematical model. By analyzing the main controlling factors and interference mechanisms, this article establishes a pattern of interlayer interference, and improves the quantitative characterization interlayer interference theory in multi-layer combined mining. The study has shown that: (1) The interlayer interference is beneficial for balancing the production of different layers and improving development efficiency, it is greatly affected by interlayer heterogeneity; (2) When the number of layers exceeds 2 layers, the interference coefficient increases; With the increase of the layer thickness, the thicker oil layers have higher productivity, and the thickness of layer has a significant effect on the production of low-pressure layer; When the production pressure difference increases, the interlayer interference can be reduced; (3) The interlayer interference mathematical model constructed in this paper has high prediction accuracy and strong practicality, which has theoretical guidance significance for the division of strata in comprehensive adjustment of reservoirs.

“They don't care what we watch”: On ratings and culture‐making in the dizi industry

AbstractThis article challenges Western‐centric assumptions in existing media theories that assume a relatively democratic society by exploring the media worlds of dizis, Turkey's globally famous, serialized television melodramas. It examines dizi makers' frustrations with a recently revised rating system at a time when Turkey's conservative and authoritarian‐leaning ruling AKP elite increasingly intervene in the country's cultural field. The article argues that in Turkey's highly polarized, authoritarian context, ratings become a crucial site of culture‐making, through which Turkish culture, the value of cultural products like dizis, and the place of their creators in Turkey's cultural hegemony get renegotiated. Exploring the resentments of today's dizi makers reveals that contemporary Turkish power contestations cannot be reduced to either the secular/religious binary or to class dynamics alone, as often deployed to explain the current polarization between Erdoğan's supporters and his dissidents. The article also demonstrates the need for more rigorous theorizing about how states—as repressive actors in authoritarian contexts—affect the worlds of media creators and their works.

The (im)possibility of communication with nonhuman beings: with digital screen printing of luminous bacteria

In the current media environment, John Durham Peters emphasizes the importance of non-verbal communication and notes that underpinned by digital technology, “media” is returning to its original meaning as the milieu that surrounds living beings. To concretize and critically discuss this idea, this paper examines the artworks created by the authors, which incorporate microorganisms into digital technology. These works applied luminous bacteria as ink to digitally screen print text and images. The first work, A Medium for Images or Luminous Bacteria (2022), prints Japanese text with luminous bacteria ink. The second work, ‘イ(I)’ (1926) by BioLuminescent Bacteria (2024), recreates the first image in the history of Japanese television, ‘イ(I)’, with luminous bacteria. This paper compares and analyzes these practices in light of classical media theory, including the work of William Ivins Jr. and Marshall McLuhan. The paper introduces another work, Grow.|Glow. (2023), to further expand the discussion to contemporary digital media. Finally, drawing on the recent arguments of Anna Tsing and Antonio Damasio, we elucidate the critical implications that the works of luminous bacteria bring to the current media environment.

Simulation method of heat-mass transfer between hot wind and wet coating in the manufacturing process of pole piece

In order to improve the complex numerical calculation process for wet coating of pole piece, a three-dimensional numerical model of heat-mass transfer characteristics is established between hot wind and wet coating based on multi-field coupling theory of porous media and meshless parallel method, and its reliability is verified through literature data. Meanwhile, the difference calculation method and evaluation process are proposed for heat-mass transfer characteristics to solve this numerical model. The results show that the maximum errors are less than 14.7 % for this model. In addition, a scale modeling method is proposed to improve computational efficiency based on similarity theory. Meanwhile, the influences of different scale factors on temperature and humidity parameters are analyzed for wet coating. The results show that this method is accurate and reliable because the determination coefficient R2 of all parameters is more than 0.99. Meanwhile, compared with the calculation time of original model, the calculation efficiency increases by 44.6 % for the model with scale factor selected as 800. Finally, the variation and distribution of internal parameters are analyzed for wet coating during pore emptying process based on above simulation method. The results show that the variation trends of liquid film thickness, pore emptying rate, water saturation, gas saturation and effective gas diffusion coefficient are corresponding with the accelerated, uniform and decelerated drying processes of porous media. Meanwhile, the location of four-corner edges for wet coating is the weak link in heat-mass transfer process. Therefore, the heat-mass transfer characteristics for wet coating can be improved by increasing its initial thickness or adjust reasonable drying position in engineering.

Beyond the Master’s Tools: In Conversation with Keller Easterling

Keller Easterling is an unconventional thinker. Spanning writing, creative practice and teaching, her work draws on disparate sources and intellectual traditions: from media theory to the philosophy of ecology; economic geography to game theory; anarchisms to feminisms; and from decolonisation to political discourse analysis. Infrastructure, mutualism, reparations, freedom, fugitivity, indeterminacy, whiteness, failure and solidarity emerge as core concerns in her wider attempts to develop an artistic approach capable of contending with contemporary forms of violence and power. In late 2023, Architectural Theory Review (ATR), in conjunction with the University of Technology Sydney (UTS), invited Easterling to discuss her recent work on the civil rights movement in the US. Easterling sat down with Endriana Audisho (UTS) and Jasper Ludewig (ATR) to elaborate on the themes and questions that emerged from this work, discussing their relevance to her scholarship, pedagogy and broader spatial practice.

Modeling freezing and BioGeoChemical processes in Antarctic sea ice

AbstractThe Antarctic sea ice, which undergoes annual freezing and melting, plays a significant role in the global climate cycle. Since satellite observations in the Antarctic region began, 2023 saw a historically unprecedented decrease in the extent of sea ice. Further ocean warming and future environmental conditions in the Southern Ocean will influence the extent and amount of ice in the Marginal Ice Zones (MIZ), the BioGeoChemical (BGC) cycles, and their interconnected relationships. The so‐called pancake floes are a composition of a porous sea ice matrix with interstitial brine, nutrients, and biological communities inside the pores. The ice formation and salinity are both dependent on the ambient temperature. To realistically model these multiphasic and multicomponent coupled processes, the extended Theory of Porous Media (eTPM) is used to develop Partial Differential Equations (PDEs) based high‐fidelity models capable of simulating the different seasonal variations in the region. All critical variables like salinity, ice volume fraction, and temperature, among others, are considered and have their equations of state. The phase transition phenomenon is approached through a micro‐macro linking scheme. In this paper, a phase‐field solidification model [4] coupled with salinity is used to model the microscale freezing processes and up‐scaled to the macroscale eTPM model. The evolution equations for the phase field model are derived following Landau‐Ginzburg order parameter gradient dynamics and mass conservation of salt allowing to model the salt trapped inside the pores. A BGC flux model for sea ice is set up to simulate the algal species present in the sea ice matrix. Ordinary differential equations (ODE) are employed to represent the diverse environmental factors involved in the growth and loss of distinct BGC components. Processes like photosynthesis are dependent on temperature and salinity, which are derived through an ODE‐PDE coupling with the eTPM model. Academic simulations and results are presented as validation for the mathematical model. These high‐fidelity models eventually lead to their incorporation into large‐scale global climate models.

Boosting third-order optical nonlinearity in ITO/Au multilayer films via interfacial effects

We present the enhancement of third-order optical nonlinearity in indium tin oxide (ITO)/Au multilayer films via interfacial effects. The overall thickness of prepared ITO and Au layer was kept as 200 nm and 14 nm, respectively, and thus multilayers are 214 nm, i.e., for the sandwich structure ITO/Au/ITO, the thickness of ITO and Au is 100 nm and 14 nm, respectively, while the thickness of ITO and Au is 40 nm and 3.5 nm in the nine-layer films composed of five layers of ITO and four layers of Au. The measured nonlinear refractive index (n2) and absorption coefficient (β) of the multilayers rise as the number of layers increases. The maximum n2 and β in the nine-layer film are 2.6×10−14 m2/W and −3.7×10−8 m/W, which are 3.8 and 2.3 times larger than the values in the pure ITO film, respectively. Such enhancement of optical nonlinearity as the number of layers increases originates from the increase of carrier concentrations in multilayers due to contact of metals/semiconductors (interfacial effects), not following the traditional effective media theory and epsilon-near-zero effect. The results pave a way to modulate the optical nonlinearity in special metal-dielectric multilayers of interfacial effects and indicates the promising applications in nonlinear photonics.

Clouds and Cows, Shields and Sheep: Some Nonhuman Sounds in Homer

Abstract: The Homeric verbs μύκε “moo,” λάκε “screech,” and μακών, “bleat(ing)” describe animal sounds but can also apply to inanimate subjects in certain contexts. This paper considers the morphology, semantics, and poetics of these verbs within two frameworks: media theory and animacy studies. Through these verbs, the poet creates a complex nonhuman soundworld of objects, animals, bodies, and material media that challenges the limits of human perception. Close analyses of the passages in which these verbs appear reveal the medial and animate complexities of well-known epic objects, such as Achilles’ shield, Hector’s body, or the cloud-gates of Olympus. The sounds of these and other things are embedded but not wholly translated into human sensory understanding; the scenes in question also challenge easy distinctions between humans and nonhumans, animals and objects, and living and dead bodies.

Local news as political institution and the repercussions of ‘news deserts’: A qualitative study of seven UK local areas

A transformation in the political economy of local news provision has led to claims that an increasing number of local areas have become ‘news deserts’ – areas that are poorly served or not served at all by professional and dedicated news services (Abernathy, 2022). Such developments have raised widespread concerns about the future health of local democracy. One aspect of local news’ declining capacity that has received little attention to date is the impact on its role as political institution. This paper first examines the impact of changes on those most closely affected by the reduction or closure of UK local news media outlets – the consumers and sources of local news. Through empirical research in 2021-22, the authors explore Cook’s theory of the news media as political institution (2005), by examining local citizens’ experience of – and attitudes towards – their local news outlets, and the extent to which they believe these continue to perform an institutional role. Second, the paper seeks to explore the extent to which other information services – most notably social media and online communities - substitute for the institutional roles of local news outlets. The paper argues that the diminishing role of local news media as political institution has significant political and democratic implications which are not being addressed by policymakers, who are more concerned with the economic interests of corporate media owners than the broader democratic and societal interests of local communities.

In silico investigation of the reliable models of drug delivery from blood vessels to tumor using tumor spheroid-on-chip models

Due to the limitations of two-dimensional models in mimicking intratumoral drug delivery, three-dimensional tumor spheroid-on-chip models have been considered recently. Even though various models have been proposed in this field, many unknowns still exist about their reliability in imitating in vivo conditions. In addition, most of these models neglect the replication of drug transport from the bloodstream. In the current research, considering the interface of tumor and blood vessels, new designs of microfluidic devices are developed to resemble the in vivo conditions more closely. Then, drug transport in the proposed models is studied numerically using porous media theory under dynamic conditions. The simulation results of drug concentration, cell viability, fluid shear stress, and pressure distributions are compared with those of a solid tumor. As the results demonstrate, our proposed models can well mimic the in vivo conditions, including drug delivery through blood vessels. Therefore, in addition to developing tumor spheroid-on-chip models resembling tumor-vessel interaction, the present study provides a strong strategy to evaluate the reliability of in vitro models in replicating intratumoral drug delivery.

The Expression of Walter De Ville’s Love Language in The Invitation Movie

The motive of this takes a look at is to analyze the principal individual in the film "The Invitation". This research uses a descriptive qualitative technique, with facts taken from the movie, within the shape of pictures or screenshots, in addition to the conversation in the movie. The concept used to discuss the language of love is the principle proposed by Dr. Gary Chapman, a couples counseling expert who brought the idea of the five love languages possessed through people. Love language is an idea that explains how a person expresses actions to some other individual as a form of love. The five love languages are words of affirmation, receiving gifts, acts of service, quality time, and physical touch. This takes a look at, it is analyzed how the principal character’s movements using these five love languages toward the woman man, or woman make her feel deeply loved. This research is expected to offer further information on the software of affection language theory in film media and how expressions of love can affect relationships among characters.

The "Female-to-Male" Phenomenon in Short Videos: A Feminist Media Analysis

Feminist media analysis is a set of critical analytical tools used to understand how different kinds of media contribute to the molding of gender and identity, which has played a crucial part in the development of feminism and the media-driven society. This paper conducts a feminist media analysis to investigate the phenomenon of "female-to-male" presentations in TikTok short videos. This paper aims to challenge some traditional notions of "performing gender," as conceptualized by digital media theories, which disrupt established performance standards and promote broader acceptance of diverse practices. Focusing on TikTok users Dayao Tongxue, Chen Lijun, Lapmoby, and Northeast Rain Sister, this research analyzes the content and influence of those influencers to understand how their performances challenge conventional norms and cultivate inclusiveness. The research concludes by examining the impact of social media on the formation of gender identity, specifically in the transition from language-sex to the identification as male or female.

#Freebritney: strategies of counternarratives and self-regulation in digital feminist counterpublics

ABSTRACT The conservatorship of Britney Spears represented a legal arrangement that placed multiple restrictions on the celebrity’s autonomy. The conservatorship also became the center of an activist movement that demanded a restoration of her rights, commonly known as #FreeBritney. Since 2009, this primarily online group has worked to raise awareness of and bring an end to Spears’ conservatorship, an objective that was ultimately achieved in 2021. Through a thematic analysis of interviews with self-identified #FreeBritney activists, we analyze this movement as a digital feminist counterpublic through two key themes: 1) #FreeBritney’s central mechanism of generating counternarratives about Britney Spears’ conservatorship and 2) its self-regulating structure. Taken together, these themes surface #FreeBritney’s feminist values, specifically regarding its attention to representation, narrative, and non-hierarchical organization practices. We argue that #FreeBritney poses compelling questions about key tensions at the intersection of fandom, digital activism, and feminist media theory. By positioning #FreeBritney as a digital feminist counterpublic that achieved its main goals, we interrogate the multifaceted nature of digital engagements with feminism, building on important work in internet, media, and feminist studies.

Validation of Math Model Using Porous Media for Determining Alveolar CO 2 in Ventilated Patients.

To validate a mathematical model using porous media theory for alveolar CO2 determination in ventilated patients. Mathematical modeling study with prospective clinical validation to simulate CO2 exchange from bloodstream to airway entrance. ICU. Thirteen critically ill patients without chronic or acute lung disease. None. Model outcomes compared with patient data showed correlations for end-tidal CO2 (EtCO 2 ), area under the CO2 curve, and Pa CO2 of 0.918, 0.954, and 0.995. Determination coefficients ( R2 ) were 0.843, 0.910, and 0.990, indicating precision and predictive power. The mathematical model shows potential in pulmonary critical care. Although promising, practical application demands further validation, clinician training, and patient-specific adjustments. The path to clinical use will be iterative, involving validation and education.

Influence of interstitial fluid pressure, porosity, loading magnitude, and anisotropy in cortical bone adaptation

Adaptive elasticity in cortical bone has traditionally been modeled using Strain Energy Density (SED). Recent studies have highlighted the importance of interstitial fluid in bone adaptation, yet no research has quantified the role of interstitial fluid pressure and its effects, specifically incorporating both SED and interstitial fluid pressure in the adaptation process. This study introduces a novel formulation combining theory of porous media and theory of adaptive elasticity that considers both SED and interstitial fluid’s pressure in cortical bone adaptation. The formulation is solved using ANSYS Fluent and a MATLAB script, and sensitivity analyses were conducted, analyzing various porosities, loading magnitudes, anisotropic properties of cortical bone, and involvement coefficients of interstitial fluid’s pressure. This study reveals that bones with different vascular porosities (PV) tend to achieve similar density distributions under uniform loading over time. This highlights the significant role of interstitial fluid pressure in accelerating the convergence to optimal bone properties, especially in specimens with larger PV porosities. The findings emphasize the importance of fluid pressure in bone remodeling, aligning with previous studies. Furthermore, this study demonstrates that considering transversely isotropic material properties can significantly alter the remodeling configuration compared to isotropic material properties. This highlights the importance of accurately representing the anisotropic nature of cortical bone in models to better predict its adaptive responses. However, aspects such as fluid density variations and bone geometry changes remain unexplored, suggesting directions for future research. Overall, this research enhances the understanding of cortical bone adaptation and its mechanical interactions.

The Theory of Gradual Landing of Public Opinion During Crises

Public opinion is under consideration not only in the media but also in other fields, such as political science, social studies, and psychology, especially with the growing crises affecting institutions and countries during the 20th and 21st centuries. It is noticeable that there are few theories that explain many of the phenomena associated with public opinion, especially in the era of modern communication technologies and social media. This gap necessitated the development of a theory of gradual landing in public opinion during crises. This theory was developed by reviewing extensive literature on public opinion, crisis management, and media theory related to public opinion. The theory deals with four major variables: event, media, audience, and the parties involved in the conflict or crisis. These variables encompass the mechanisms that determine the paths on the rise and decline of public opinion issues. This theory integrates the degree of the significance of the topic and the media's interest. This theory helps identify various cases of rise and decline in the level of interest in public opinion within society.
