Abstract:

From having been associated with poverty and low status, the commerce with second-hand goods in retro shops, flea markets, vintage boutiques and trade via Internet is expanding in Sweden as in many countries in the Global North. This article argues that a significant aspect of the recent interest in second-hand and reuse concerns the meaning fulness of circulation in social life. Using classic anthropological theory on how the circulation of material culture generates sociality, it focuses on how second-hand things are transformed by their circulation. Rather than merely having cultural biogra

Abstract:

Kerta Barat Village in Dasuk District is one of several tomato and chili producing areas in Sumenep Regency. The economic potential of processed food production from agricultural commodities is considerable. This potential can be further increased by harvest abundance. Tomatoes and cayenne chillies are categorized as agricultural commodities with a shelf life and are difficult to store for long periods. The best solution to the overabundance of crop products is by processing these agricultural materials into processed products capable of extended periods of storage. Additionally, processed foo

Abstract:

Cassava is one of the commodities of food crops that mainly processed in food products. In addition to being the raw material, cassava food products also have the potential as raw materials for making bioplastics. Processing cassava into bioplastics is carried out by bio-industrial, so the discussion about the process of utilizing cassava up to being bioplastic is interesting to explore. The results of descriptive analysis and literature sharing show that the cassava bio-industry is more environmentally friendly because the production in the form of bioplastic is easier to decompose compared t

Rooted in the tradition of eighteenth-century circulation novels recounted by an object narrator, The Adventures of a Black Coat (1760) epitomizes the features of this experimental novelistic subgenre by foregrounding a coat which, acting as a homodiegetic narrator, lambastes the world of commodities prompted by the rise of early capitalism. As an object endowed with moral conscience, the coat epistemologically proves to be a reliable narrator that is able to render authentic experience and feelings by getting empirically involved in the world it describes.

The growth and transformation of logistics have been attributed to a specific confluence of forces that compelled firms to turn their attention to the circulation of commodities in the second half of the 20th century. This article seeks to develop a more theoretically informed account of the logistics revolution by delineating the industry’s role in promoting the accumulation of capital and the reproduction of capitalism. Drawing on Marxian geographical thought, I contend that the logistical turn of the past five decades has facilitated a multifaceted “spatial fix” to capitalism’s chronic prob

Abstract:

This paper analyzes the very important notion of capital from a Marxian perspective as opposed to a neoclassical one. It is argued that when capital is viewed as a historically determined social process (relation), rather than as a thing or a col-lection of things, it tends to assume certain specific forms more often than others depending on the particular stage of economic history. Capital thus refers simulta-neously to social relations and to things. Given this frame of reference, notions such as money and property capital are more easily accommodated and conse-quently are not written off as

Abstract Gaussian process emulators are a powerful tool for understanding complex geophysical simulators, including oceanic and atmospheric general circulation models.

This simple example also shows how an emulator can help to elucidate interactions between parameters. The ideas are further illustrated with a second, more realistic,

Abstract Given the recent changes in the Arctic sea ice, understanding the effects of the resultant polar warming on the global climate is of great importance.

It is shown in this note that a simple statistical model that treats the Indian Ocean as a red noise process forced by tropical Pacific SST shows forecast skills comparable to those of recent general circulation model studies.

But capitalism also involves circulation, which casts the sea into a space of contradictions. On the one hand, the oceanic expanse can be an image for the flow of capital and c

Summary Steam-assisted gravity drainage (SAGD) is the preferred method to extract bitumen from Athabasca oil-sand reservoirs in western Canada. Bitumen at reservoir conditions is immobile because of high viscosity, and its saturation is typically large, which limits the injectivity of steam at in-situ conditions. In current industry practice, steam is circulated within injection and production wells. In theory, wells should be converted to SAGD production mode after a period when bitumen is mobile and communication is established between the injector and the producer. Operators use temperature

Abstract:

Companies and R&D institutions increasingly collaborate not only in isolated projects but also in knowledge-based networks. In those networks, participants combine expertise and applied problems to generate both ‘problem-solving knowledge’ and specialized knowledge: during the process of common problem-solving each partner acquires some of the specialized knowledge of the other partners as well as the newly generated problem-solving knowledge. This article examines the basic principles involved and provides a simple mathematical description of the step-by-step accumulation of knowledge thr

Abstract:

Abstract Climate models consistently predict a strengthened Brewer–Dobson circulation in response to greenhouse gas (GHG)-induced climate change. Although the predicted circulation changes are clearly the result of changes in stratospheric wave drag, the mechanism behind the wave-drag changes remains unclear. Here, simulations from a chemistry–climate model are analyzed to show that the changes in resolved wave drag are largely explainable in terms of a simple and robust dynamical mechanism, namely changes in the location of critical layers within the subtropical lower stratosphere, which are

Ultrasound microbubble combined optic protection drugs have obvious protective effect on optic nerve damage. This way of targeting drug delivery is becoming more simple, not through the whole body metabolism, avoiding drug via blood circulation when facing the decomposition and the environment in the interference and destruction process of drugs, to maximize the guarantee to reach target organs of drug concentration and to reache the maximum therapeutic effect. The technique of ultrasound microbubbles is safe, controllable, nonimmunogenic, and repeatable. It provides us with a novel idea in th

Abstract The mechanisms that control the interhemispheric teleconnections from tropical heat sources are investigated using an intermediate complexity model [a quasi-equilibrium tropical circulation model (QTCM)] and a simple linear two-level model with dry dynamics. Illustrating the interhemispheric teleconnection process with an Atlantic warm pool principal case, the heat source directly excites a baroclinic response that spreads across the equator. Then, three processes involving baroclinic–barotropic interactions—shear advection, surface drag, and vertical advection—force a cross-equatoria

Abstract The role of cumulus congestus (shallow and congestus convection) in tropical cyclone (TC) formation is examined in a high-resolution simulation of Tropical Cyclone Fay (2008). It is found that cumulus congestus plays a dominant role in moistening the lower to middle troposphere and spinning up the near-surface circulation prior to genesis, while deep convection plays a key role in moistening the upper troposphere and intensifying the cyclonic circulation over a deep layer. The transition from the tropical wave stage to the TC stage is marked by a substantial increase in net condensati

Abstract A dynamical interpretation is made of the mesoscale eddy buoyancy fluxes in the Eastern Boundary Currents off California and Peru–Chile, based on regional equilibrium simulations. The eddy fluxes are primarily shoreward and upward across a swath several hundred kilometers wide in the upper ocean; as such they serve to balance mean offshore air–sea heating and coastal upwelling. In the stratified interior the eddy fluxes are consistent with the adiabatic hypothesis associated with a mean eddy-induced velocity advecting mean buoyancy and tracers.

A simple, semi-analytical heat extraction model is presented for hydraulically fractured dry reservoirs containing two subparallel horizontal wells, connected by a horizontal fracture channel, using injected brine as the working fluid. Heat equations are used to quantify the heat conduction between fracture walls and circulating brine. The brine temperature profiles are calculated for different combinations of fracture widths, working fluid circulation rates, and initial fracture wall temperatures. The longevity of the geothermal heat extraction process is assessed for a range of working fluid

For deeper reservoirs, the heat losses from injection wells may be prohibitive. A technology that may be better suited is oil recovery aided by low-frequency electrical heating of the reservoir. This technology, well known for environmental remedial applications, has been field tried recently, yielding promising results.

Abstract A simple conceptual model of surface specific humidity change over land is described, based on the effect of increased moisture advection from the oceans in response to sea surface temperature (SST) warming. In this model, future q over land is determined by scaling the present-day pattern of land q by the fractional increase in the oceanic moisture source. Simple model estimates agree well with climate model projections of future (mean spatial correlation coefficient 0.87), so over both land and ocean can be viewed primarily as a thermodynamic process controlled by SST warming.
