Mode Of Accumulation Research Articles

Methodology of scientific selection of accumulation modes and preliminary heat treatment of forgings made of medium carbon medium alloy steels

This article considers issues related to the forgings from medium-carbon medium-alloyed steel grades. It is necessary to take into account the processes of phase and structural transformations when assigning modes of accumulation of ingots after forging and preliminary heat treatment (PHT). The main provisions of the appointment of PHT modes were analyzed. The paper formulates their limited application when using diagrams of isothermal transformation of austenite, built according to standard techniques.

The historical logic of the mode of capital accumulation in Mozambique

ABSTRACT This article critically analyses the political economy dynamics and trajectory of the mode of capital accumulation in post-independence Mozambique, focusing on the capitalist restructuring that followed the adoption of the Washington Consensus from the late 1980s. The article highlights the main structural characteristics, dynamics and tensions in the economy, the relationships and conflicts that explain why they reproduce and expand, what makes them change and the nature of the crises that emerge. The historical logic of the mode of capital accumulation is explored focusing on the historically built and class-structured conditions of capital accumulation, highlighting linkagency, which is the dynamic relationship between agents and linkages. The historically specific traits of the mode of accumulation in Mozambique are derived from the structures of accumulation and class struggle conditions, both domestic and international. The argument is that the recent trajectory of the Mozambican economy was not inevitable, and that it can be logically understood and derived from the existing historical conditions of accumulation. Understanding this historical logic enables us to articulate socially transformative actions which are drawn from the objective and concrete analysis of the mode of accumulation and its contradictions, countering idealistic perspectives in political economy.

Financialisation, narrow specialisation of production and capital accumulation in Mozambique

ABSTRACT The article argues that the historical conditions under which national capitalism developed in post-independence Mozambique pushed the economy towards growing financialisation and narrower specialisation of production around increasingly basic and simple activities. In post-independence Mozambique, national capitalism rose from the ashes of state-centred accumulation built around the dominant social structures of production inherited from colonialism, under the impulse of neoliberal economic reforms and heavy dependency on inflows of private international finance. The speculative dynamics of accumulation prevented diversification and more complex industrialisation which, in turn, reinforced the role of financialisation as a means to and form of accumulation of capital. The paper argues that changing these dynamics of accumulation requires conscious industrial strategies focused on diversification and articulation of production, which cannot be achieved without challenging the extractive mode of accumulation and the power relationships associated with it.

Racialized Obsolescence: Multinational Corporations, Labor Conflict, and the Closure of the Imperial Typewriter Company in Britain, 1974–1975

AbstractThis article will explore one of the most significant strikes by migrant workers in Britain during the 1970s and the subsequent company closure the year after their victory. In May 1974, a predominantly South Asian workforce at the Imperial Typewriter Company in Leicester went on strike over unequal bonus payments and discrimination in promotion. The shop stewards committee and Transport & General Workers Union branch refused their support and the workforce split partly on racial lines. The strikers stayed on strike for almost 14 weeks until they emerged victorious. Though it appears as a central reference point in histories of migrant experience in Britain, the strike and closure has garnered little systematic, primary research. This article will fill this gap through the use of published sources and extensive unused archival deposits. During the strike part of the largely South Asian workforce sought to break with the racialized division of the workforce between different groups, skill levels, and work-types. Almost immediately after the strike ended in victory the company announced its intention to close down the vast majority of its British production. In Hull 1400 jobs were lost and in Leicester over 1600 were to go. This article shows that whilst the strike might have been the start of a politically, culturally, and intellectually significant period of significant protagonism by Britain's first-generation black and racialized working class, it also marked the beginning of the end of an industrial model dependent on the hyper-exploitation and racialized subordination of their labor. The closure was framed by contemporaries and subsequent historical accounts as a dispute marked more by the end of empire than worker obsolescence. As an article in the Guardian on the closure of the plants was put it in January 1975, it was ‘The day that Imperial&s empire fell'. Yet it might be more accurate to understand the strike as an early premonition of the globalisation of manufacturing production which was to emerge strongly in the 1980s and 1990s. The experience of Imperial Typewriters highlights the central importance of racialized labour hierarchies and immigrant counter-militancy in post-war Britain. The Imperial Typewriter Company provides a case study of how worker resistance to labour intensive modes of capital accumulation, in relatively low capital intensive industries, during a global crisis of capitalist profitability, was followed by the decision of a multinational corporation to immediately transfer its production overseas. The closure of Imperial Typewriters therefore offers a means to reconceptualize how we understand the 1970s as a period of interlocking crises, as well as the major shift of power from labour to multinational capital which emerged in its wake. The findings of this article indicate that British workers were significantly disempowered before the electoral victory of Margaret Thatcher in 1979. Recentering labor conflict in the history of technological obsolescence can offer alternative perspectives on why the British left and trade unions were unable to resist the rise of neoliberalism.

The hydrocarbon accumulation regularity and the model of hydrocarbon accumulation along the fault ridges in the slope zone of the continental fault basin

The slope zone of fault basin has a large area and high hydrocarbon potential. Its relatively highly scattered reservoirs and vastly different accumulation characteristics make it difficult to accurately determine the main controlling factors of hydrocarbon accumulation. To solve this problem, we adopt the 3rd member of the Funing Formation (Ef3) in the slope zone of the Qintong Sag as an example to identify the main controlling factors of hydrocarbon accumulation in the slope zone of the Paleogene continental fault basin. The results reveal that there are two critical intervals for Ef3 in the Qintong Sag slope zone, namely, the Late Paleogene to the Early Neogene (23.2–20 Ma) and the Late Neogene to the Early Quaternary (2 Ma until now), and the crude oil comes from the source rock of the second member of the Funing group related to the slope barrier and the inner slope zone. Instead of migrating directly into the traps in the slope zone, three main paths of hydrocarbon migration were developed: First from southwest to northeast and then from northeast to southwest; From northeast to southwest; From west to east directly. Oil and gas migrated along the sand body in the northeast and southwest directions and bypassed by the central antithetic fault terrace, thus forming the mode of accumulation along the fault edge.

An introduction to heavy metal pollution and different technologies available for remediation

This paper revises the fundamental facts about potentially toxic elements belonging to the group of heavy metals. The study highlights the ongoing soil pollution status affected by these non-biodegradable elements, the basic characteristics of these metals that make them toxic, their mode of accumulation in different trophic levels, their toxic effect on human beings and the probable remediation technologies being used to remediate soils contaminated with heavy metal when the pollution problem has evolved. The technologies focused on solidification, soil washing, soil flushing, electro-kinetic remediation and phytoremediation are presented. The choice of the technology to be used for remediation depends on the condition of the soil and the extent of contamination. Conventional electro-kinetics is the most effective and rapid technology, but on the scale of ecosystem restoration, phytoremediation is an eco-friendly, green and cost-effective solution.

Biofortification of wheat with Mn through tank mixed formulations of MnSO4 7H2O and CO(NH2)2—a fast mode of Mn accumulation on light textured soils of Punjab, India

In the Indo-gangetic plains, the continuous cultivation of rice-wheat cropping system in light-textured soils has aggravated a manganese (Mn) deficiency. Wheat is sensitive to Mn availability in soil and its deficiency has become one of the major constraints in sustaining its productivity on soils cropped with rice. Thus, field experiments were conducted to evaluate the response of tank-mixed formulations of manganese sulfate (MnSO4·7H2O) and urea (CO(NH2)2) at critical growth stages. The experiment comprised of six different treatments of MnSO4·7H2O (0.5%) and tank-mixed formulation of MnSO4·7H2O (0.5%) and CO(NH2)2 (1%) sprayed 35, 50 and 70 days after sowing (DAS). The results revealed that for biofortification, tank mixed formulation of MnSO4·7H2O (0.5%) with and without CO (NH2)2 (1.0%) at different growth stages resulted in significantly higher yield and Mn accumulation over control. The protein content, micronutrient concentrations (Zn, Fe and Mn) and accumulation in wheat were highest in the treatment having tank-mixed formulation of MnSO4·7H2O and CO(NH2)2 at 35, 50 and 75 DAS stages. However, it was statistically at par with tank-mixed formulation of MnSO4·7H2O (0.5%) and CO(NH2)2 (1.0%) sprayed at 35 and 50 DAS. The net return and B:C ratio were maximum (Rs 75,671 ha−1 and 2.97) in the treatment having tank-mixed formulation of MnSO4·7H2O plus CO(NH2)2 applied at 35 and 50 DAS. The results of the study concluded that the tank-mixed formulation is the appropriate combination for higher accumulation of Mn in wheat grains through biofortification.

The crisis of social reproduction and 'Made-in-China' feminism

Crises of care and social reproduction have led to new debates and social movements around the world, but there has been little scholarly scrutiny in the global North on these issues as they are unfolding in China. Facing rapid population ageing and historically low birth rates, the Chinese government believes the country is suffering from a demographic crisis. Yet, the so-called population question is fundamentally a political one: who is bearing the brunt of biologically and socially reproducing the Chinese labour force who have fuelled the Chinese economy in the last four decades? As this essay unpacks, the country's long-existing urban-rural divide and the unchecked patriarchal-capitalist mode of accumulation have produced uneven consequences among different social groups, intersectionally defined by class, gender and urban/rural citizenship, and thus have exacerbated existing inequalities. Rural migrants and the urban poor, mostly women, have become domestic servants for urban middle-class families, at the cost of their own well-being and of their families and communities. Across social classes, Chinese women are making their voices heard and taking actions to protest against systemic appropriation and exploitation of their care and reproductive labour, in what is a hostile political environment. Ranging from organised protests to individuals' spontaneous complaints, 'made-in-China' feminism can shed new light on future feminist movements and solidarity building with feminists in the international community.

Promissory shock, broken future: COVID-19 and state-led speculations in biotechnology and pharmaceutical industries in South Korea

This research examines institutional responses to shocking events, in this case, the COVID-19 pandemic and beyond. I argue that our analysis should consider state-led nationalism in finance and financialization especially when new modes of financial accumulation can be correlated with state projects of crisis management. Also, in dealing with shocking events, which are an inevitable aspect of capitalism, I claim nationalistic deregulations and speculation stimulated by institutional discourse can put ordinary people into permanently unpayable debt and reshape social exclusion. Drawing from interpretative policy analysis, I examine how early COVID-19 management by the Korean government took advantage of sloganeering of upper-K words, initiated by the Korean Wave, as discursive tools in invoking nationalistic sentiments. The instutional nationalism in the upper-case K as prefix is examined in promoting Korean biotechnology and pharmaceutical companies and their stocks. Further, I demonstrate how the accumulation strategies of this nationalistic COVID-19 management regarding bio and pharma industries were already practiced before COVID-19 in Korea, by the regulatory sandbox policy along with the Korean legitimation crisis. This set of practices has eventually accelerated the financialization of everyday life and Othering. I call for a critical lens to analyze the pressing agenda of discursive practices in institutional crisis responses.

“We’re Still Here”: An Abolition Ecology Blockade of Double Dispossession of Gullah/Geechee Land

Narratives of resilience to sea-level rise too often perpetuate social violence. An abolitionist climate justice praxis necessitates seeing beyond physical inundation to sea-level rise as the sole issue. We argue that sea-level rise is environmental racism, if not always in its racialized outcomes of disproportionate harms, then always in its racialized production of differential value. More than mitigating flood risk when developing Black land futures strategies, to mitigate coastal land loss in the face of rising seas necessitates dismantling “racial regimes of ownership” that are imbued in property relations. Recognizing such, we argue that land futures strategies in the face of rising seas must account for multiple capitalist modes of accumulation but specifically the primitive accumulation process connected to heirs’ property. Here, we argue that racial coastal formations are still underway in how sea-level rise and gentrification are leading to a double dispossession of land and displacing Gullah/Geechee people on Sapelo Island. Although such displacement precipitates loss through harm and violence, in this article we share strategies from abolition ecology praxis to “blockade” these double dispossession processes and, to a degree, even the narrative of loss. To situate the double dispossession narrative within a broader praxis that imagines alternative futures, we till the soil, trace the archives, and tread the marsh and drainage ditches with each other, and in solidarity with other residents, to work toward achieving agricultural revival, property retention, and flood risk mitigation.

System for measuring and analysis of vibration in electric motors of irrigation facilities

This article analyzes the vibration process that occurs in electric motors in irrigation facilities. It has been studied that various failures and electric motor imbalances and vibrations that can occur during the operation of electric motors at pumping stations have a negative impact on the whole system. Electrical and mechanical failures affect the normal operation of the electric motor, i.e. increase power consumption, increase current, increase heat, and also increase vibration. Balancing is an important requirement for electric motors and all rotating components. A modern SD-21 vibrodiagnostic device was used to detect vibration. The research was carried out using the method of comparing the trajectory obtained in the mode of synchronous accumulation using the vibrodiagnostic device SD-21. In the course of the research, the main factors that cause vibration in electric motors, the method of identification of decentralization that causes high vibration, the spectral and informative properties of vibrating signals were studied. The advantages of predicting the deviation of vibrations in electric motors from the allowable are highlighted. A virtual tool has been developed to detect and analyze vibration.

Introducing the YIMBYs: Renters, housing, and supply-side politics in Los Angeles

This paper advances debates around the financialization of housing with a case study of Los Angeles’s yes-in-my-back-yard (YIMBY) groups. In response to the post-2008 affordable housing crisis, YIMBYs have emerged in support of orthodox economic policies that deregulate land use, expedite construction, and intensify financial accumulation in rental housing. Using detailed empirical analysis collected from YIMBY housing activists, this paper examines how the market-based logics they advance take root in local land use issues. It focuses specifically on the impact of YIMBYs on existing divisions within urban politics, including the scale at which housing is contested. By conceptualizing the YIMBY position as one that facilitates financialization, this paper reveals the ways financialization is more than a mode of accumulation: it is a political process embedded in the state from the bottom up and inside out.

Relationship Between Microbial Growth and Hydraulic Properties at the Sub-Pore Scale

Accumulation of microbial biomass and its influence on porous media flow were investigated under saturated flow conditions. Microfluidic experiments were performed with model organisms, and their accumulation was observed in the pore space and on the sub-pore scale. Time-lapse optical imaging revealed different modes of biomass accumulation through primary colonization, secondary growth, and filtration events, showing the formation of preferential flow pathways in the flooding domain as result of the increasing interstitial velocity. Navier–Stokes–Brinkmann flow simulations were performed on the segmented images—a digital-twin approach—considering locally accumulated biomass as impermeable or permeable based on optical biomass density. By comparing simulation results and the experimental responses, it was shown that accumulated biomass can be considered as a permeable medium. The average intra-biomass permeability was determined to be 500 ± 200 mD, which is more than a factor of 10 larger than previously assumed in modeling studies. These findings have substantial consequences: (1) a remaining interstitial permeability, as a result of the observed channel formation and the intra-biomass permeability, and (2) a potential advective nutrient supply, which can be considered more efficient than a purely diffusive supply. The second point may lead to higher metabolic activity and substrate conversion rates which is of particular interest for geobiotechnological applications.

Economic and ecological rationalities: uses and abuses of the political exceptionality in the COVID-19 pandemic

Introduction. This article discusses some anthropological and sociological slight reflections about the uses and the abuses of the political exceptionality in the Covid-19 pandemic. The relevance is connected with questions about the "New Norm", permeated with the daily destructiveness of antisocial metabolic practices of an even more predatory capitalism, whose social control cannot regulate violent neoliberal extraction in a mode of accumulation.
 Aim and tasks. The purpose of the article is to study the gradual resumption of interrupted social activities as a policy measure to combat the New Coronavirus Pandemic is placed from the perspective of its economic and ecologic rationalities as well as from the perspective of the new moral, emotional, cognitive, and behavioral demands directed to the common social actor and agent of big and small cities.
 Results. The article substantiates the context of the so-called "new norm", permeated by the daily destructiveness of antisocial metabolic practices of even more predatory capitalism in a violent neoliberal form. Therefore, due to this discrepancy between legality and legitimacy, the level of authoritarianism and further growth of inequality and indifference among people increases. In the context of the Covid-19 pandemic, there is a mismatch between legality and legitimacy, as well as the legitimization of the interests of individual actors in the market as opposed to the adoption of legislation and for pro-capital interests. The principles of legitimacy were limited by bureaucratic rationality and the genocidal legalism of neoliberal politics.
 Conclusions. The pandemic has disrupted economies, has mainly punished the poorest and most underserved and has destabilized governments of various ideological nuances. Participants at all levels of the economy will suffer the most severe and immediate consequences of all losses. This is the controversial logic of capital and one of its main contradictions is revealed.

Inequality of Safety and RISK in Korea: Unstable Workers at Risk

Purpose: This paper focuses on the microscopical and qualitative evolution of the mode of capital accumulation by the capitalist system based on market expansion. It will discuss how ‘the changed’ conditions surrounding humans in 21st century capitalism are fundamentally inconsistent with the essentially ‘unchanging’ needs for human safety, and ultimately how this is regressing the discussion of human nature.To this end, this paper attempts to examine the following questions: First, who enjoy the right to security that is in touch with the essential human needs, or who are the main exposure to danger? Second,how does the inequality of wealth lead to the inequality of risk? Method: To investigate the above research questions this study focuses on the number of industrial accident deaths in Korea, which is more than twice the number of deaths from Corona 19, and analyzes who are more at risk. To this end, the Ministry of Employment and Labor s industrial accident statistics were used to analyze which workers are more exposed to risk.Based on this objective data showing the level of inequality of risk, this study tries to interpret qualitatively the fundamental reasons for it from the critical perspective of capitalistic accumulation. Results: The need for safety is an essential trait for all human beings, but it is always changed and refracted according to social and class conditions. That is, the reality proves very well that safety is commercialized and that members of society are in an unfavorable situation with regard to risk. Risk inequality is multiply structured between developed and developing countries, primary and subcontracted firms, and regular and nonregular workers. Developed countries and subcontractors are trying to pay safety costs at a lower price through outsourcing of risks rather than internal investment in safety, and in the end, it is workers engaged in unstable labor that bear this outsourcing risk. Conclusion: The intrinsic need for safety is the same for everyone and therefore for all workers.However, if safety is not distributed fairly and only some people can be exposed to danger, workers who can purchase safety based on a stable material base will want to avoid the risk as far aspossible. The veto power to avoid exposure to risk in a commodified capitalist system of safety can only be exercised on a stable material basis.On the other hand, unstable workers with weak material bases have low bargaining power to reject risks and instead have high dependence on market income. Therefore, in order to secure safety, market income must be earned even at the expense of safety rather than the ability to pay the price of safety.

IS FEATURES OF THE LEGAL REGIME OF WATER FACILITIES USED FOR THE NEEDS OF HYDRO POWER

The article examines the features of the legal regime of water bodies used for hydropower. The water potential of the state is the natural basis of its economic development, social and environmental well-being. One of the main consumers of water resources is hydropower, which is one of the most promising areas of alternative energy. It was found that the category of legal regime occupies a special place in the system of legal regulation of public relations. It lays the foundations for the use and protection of water resources in general and water bodies used for hydropower in particular, taking into account the general and specific features inherent in legal regimes. It is established that Art. 66 of the Water Code of Ukraine is devoted to the peculiarities of special water use and use of water bodies for hydropower needs, but the provisions of this article do not disclose all features of the legal regime of water use for such purposes, and its practical significance is limited due to its reference to other water, land, tax legislation, technical regulations, etc. The legal regime of water bodies used for hydropower needs is characterized by such elements as ownership, management in the field of use and protection of water bodies, their legal protection, legal regulation of the use of such objects, legal liability for violations of the law in in this area, etc. The special features are that the use of water bodies for the needs of hydropower is carried out for a fee without a permit, without the removal of water resources from the water body, is indefinite. Water users are obliged to: adhere to the established rules of operation of reservoirs, conditions of special water use, modes of accumulation and operation of water reserves, environmental requirements; take measures to reduce water consumption (especially drinking); to ensure the regimes of fluctuations of water levels in the upper and lower reaches and the passage of water through hydroelectric power stations, uninterrupted passage of vessels and fish to spawning grounds in accordance with the projects of fish pass structures, etc.

3D probabilistic cellular automation modeling of transition to fracture in rocks under loading

The three-dimensional model of the probabilistic cellular automaton, which has previously been constructed on the basis of the kinetic theory of strength, is studied in this paper. It describes the process of rock damage accumulation and formation of a damage cluster structure. Comparing the kinetic curves of damage accumulation and correlation functions of the model experiments, it is found that, depending on the sprouting probability of the damage cluster perimeter, which simulates the rate of material fracture under the action of local overstresses near the existing damage clusters, two qualitatively different modes of damage accumulation are observed in the 3D model. For the sprouting probabilities of the cluster perimeter higher than 0.2, the process of transition to irreversible fracture is significantly accelerated and becomes strongly correlated. Along with this, the best agreement of correlation functions in the model and in the physical experiments is observed for the sprouting perimeter probability values smaller than 0.2.

The selective cytotoxicity of silver thiosulfate, a silver complex, on MCF-7 breast cancer cells through ROS-induced cell death

BackgroundSilver is a transition metal that is known to be less toxic than platinum. However, only few studies have reported the anticancer effects of some silver complexes and their possibility as an alternative to platinum complex. This study investigated the anticancer effects of the silver thiosulfate complex (STS), [Ag(S2O3)2]3−, consisting of silver and sodium thiosulfate.MethodsIn vitro cytotoxic activity of STS was investigated comparatively in human cancer cell lines (K562 and MCF-7) and normal human cells (mesenchymal stem cells and mammary epithelial cells). For its anticancer effects, cell cycle, mode of cell death, morphological changes, and accumulation of intracellular ROS and GSH were evaluated in MCF-7 to provide mechanistic insights.ResultsSTS showed a concentration-dependent cytotoxicity in MCF-7 cell, which was abolished by pretreatment with N-acetylcysteine, suggesting ROS accumulation by STS. Moreover, STS caused cell cycle arrest at the G1 phase, decrease in the GSH levels, and morphological changes in MCF-7. Direct measurement of ROS demonstrated the elevation of intracellular ROS accumulation in cancer cells treated with STS; however, neither cytotoxicity nor ROS accumulation was observed in normal human cells.ConclusionThe results obtained here are the first evidence to show that STS exhibited an anticancer activity through ROS-induced mechanisms, and that its cytotoxicity is highly selective to cancer cells. The results of the present study warrant further investigation on the detailed mechanism of STS actions, as well as its in vivo effectiveness and safety for clinical application.

Reversing the catastrophe of neoliberal-led global capitalism in the time of coronavirus: Towards a democratic socialist alternative

This article first outlines key arguments that demonstrate how the ‘neoliberal model of development’s’ global unleashing of capital is leading human civilisation to the brink of collapse. This ‘intellectual pessimism’ informs the ‘optimistic will’ central to the second part of this article which outlines an alternative democratic socialist model of development. This alternative is founded on a project of global cooperation to construct a national-trans-national regulatory architecture that can facilitate an ecologically balanced, materially secure, flexible and democratically solidaristic collection of local accumulation regimes that in aggregate would comprise a sustainable, progressive and pandemic-preventing planetary mode of accumulation.

Global Fertility Chains: An Integrative Political Economy Approach to Understanding the Reproductive Bioeconomy

Over the last two decades, social scientists across disciplines have been researching how value is extracted and governed in the reproductive bioeconomy, which broadly refers to the various ways reproductive tissues, bodies, services, customers, workers, and data are inserted into capitalist modes of accumulation. While many of these studies are empirically grounded in single country–based analyses, this paper proposes an integrative political economy framework, structured around the concept of “global fertility chains.” The latter articulates the reproductive bioeconomy as a nexus of intraconnected practices, operations, and transactions between enterprises, states, and households across the globe, through which reproductive services and commodities are produced, distributed, and consumed. Employing a diffractive reading of the literature on commodity chains and care chains, this unified approach scrutinizes the coproduction of value, biology, and technoscience and their governance mechanisms in the accumulation of capital by taking into account (1) the unevenly developed geographies of global fertility chains, (2) their reliance on women’s waged and unwaged reproductive labor, and (3) the networked role of multiple actors at multiple scales without losing sight of the (4) constitutive role of (supra)national states in creating demand, organizing supply, and accommodating the distribution of surplus value. We empirically ground this integrative political economy approach of the reproductive bioeconomy through collaborative, multisited fieldwork on transnational reproduction networks in Israel/Palestine, Romania, Georgia, and Spain.
