COREX and COSRI smelting reduction iron-making process could directly use coal as reductant. So it is necessary to contrast the development and technology of two kinds smelting reduction iron-making process. Due to lack of funds, COSRI smelting reduction iron-making process has not been fully developed. And the COREX has completed the transformation to the industrial production. But on the whole, COSRI has good prospects for development as COREX.

In this paper, self-characteristics (the room-temperature characteristics and the high-temperature characteristic) of iron ores used in sintering, such as chemical composition, size distribution, assimilation, liquid phase fluidity, self-strength of bonding phase, etc, were studied. Then, the principles of ore-proportioning optimization basing on self-characteristics of iron ore during sintering were proposed. Schemes of ore-proportioning optimization were designed and sinter pot test were carried out．Results of sinter pot confirmed the method of optimizing ore proportioning based on iron ore self-characteristics. This work provides good countermeasure for improving sinter quality and reducing sinter cost as soon as possible, under the condition of making full use of the existing iron ore resources.

A method of producing steel that is not used in Sweden today is direct reduction using natural gas, a method which could has enormous potential in the future of steelmaking. Historically, steelmaking prioritized productivity and profitability. However, other aspects such as safety, sustainability, and environmentally friendliness have become increasingly important to Swedish steelmakers. This study evaluates the usage of natural gas to  directly reduce iron ore into the porous form known as iron sponge, then finally processing that sponge into crude steel. The technology available today is assessed through a literature review, then two calculative data-based model: using DRI sponge in a traditional integrated steelmaking line or replacing steel scrap with it in an electric arc furnace. While this technology is used in many regions where natural gas is plentiful, it has not yet been used in Sweden. Now, when the Swedish natural gas network is expanding and the vehicular transportation of liquid natural gas is becoming more and more viable, it is a prime situation to evaluate direct reduction in Sweden. While models require assumptions and estimations, they suggest that DRI will absolutely be a viable option in the years to come. Integrated plant operators can reduce their immense carbon emissions for a reasonable price, while DRI sponge melting in an electrical arc furnace can either help steelmakers escape the volatile scrap market or be used to replace the blast furnace as a whole in the future.
En metod för att producera stål som inte används i Sverige idag är direkt reduktion med hjälp av naturgas, en metod som har en enorm potential i framtida ståltillverkning. Historiskt har ståltillverkningen prioriterat produktivitet och vinst, men säkerhet, hållbarhet, och miljövänlighet har blivit områden mer och mer viktiga för svenska ståltillverkare. Den här studien utvärderar användningen av naturgas för att direkt reducera järnmalm till den porösa formen känd som järnsvamp, och sen bearbeta den till primärt stål. Teknologin som flnns idag utvärderas genom en litteraturstudie, vars data beräknas till två scenariomodeller: användningen av järnsvamp i ett traditionellt integrerat stålverk eller genom att ersätta stålskrot med järnsvamp i ljusbågsungen. Den här teknologin används redan idag i regioner där naturgas är lättillgängligt, men har hittills inte använts i Sverige. Men nu när Sveriges naturgasnät byggs ut och fordonstransporterad flytande naturgas blir mer och mer kostnadseffektiv så är det lämpligt att utvärdera direkt reduktion i Sverige. Modellerna kräver antaganden och uppskattningar, men de pekar på att direkt reducering av järnmalm kommer att vara en genomförbar metod för ståltillverkning i en nära framtid. Integrerade masugnslinjer kan minska sina enorma koldioxidutsläpp till ett rimligt pris, och järnsvampssmältning i ljusbågsugn kan hjälpa ståltillverkare att undanfly den instabila stålskrotsmarknaden eller användas för att helt ersätta masugnsproduktion i framtiden.

Dans les années 1850 – 60, sous la politique de fermeture du pays, les Japonais ont entrepris la fabrication de canons à partir d’un ouvrage néerlandais, Het Gietwezen in’s Rijks Ijzer-geschutgieterij te Luik (Description de la fabrication des bouches à feu à la Fonderie des Armes à feu de Liège), écrit par U. Huguenin. Cet ouvrage avait probablement été introduit en 1836, avant d’être traduit en japonais, la présence de navires de guerre occidentaux exigeant l’ouverture du pays se faisant plus fréquente. Les Japonais voulaient ainsi introduire la métallurgie occidentale pour mouler des canons et renforcer la défense côtière. Cependant, réaliser un travail pratique à partir de l’écrit n’était pas simple, les Japonais n’ayant pas la même culture technique que les Occidentaux. Cette entreprise n’était pas un simple transfert dans le domaine de la métallurgie qu’il s’agissait d’intégrer, mais engageait toute la filière technique autour de la production de canons. Ils ne connaissaient ni la brique, ni le moulin à eau, ni la foreuse. Malgré la production traditionnelle du fer et des canons en bronze, ils devaient « re-concevoir » tous les éléments intervenant dans le travail : matières premières, construction avec des briques, température de four, contrôle de la fonte, moulage de canon en fer, etc. Ce fut à travers une série « essais – erreur » qu’ils ont pu assimiler ces nouveaux matériaux et ces nouvelles pratiques constituant ainsi la base ultérieure de l’industrie japonaise. Cette étude se fonde, non seulement sur des archives, mais aussi sur des données archéologiques. En effet, quatre fours à réverbère, ayant servi à fondre la fonte de fer, sont conservés à Nirayama au Japon. Elle vise à montrer comment des concepts scientifiques et techniques peuvent être compris et appropriés à partir de la seule traduction des textes étrangers
Abstract: In the years 1850 -1860, under the policy of closure to foreigners, the Japanese tried to manufacture cannons from the Dutch book, Het Gietwezen in’s Rijks Ijzer-geschutgieterij te Luik (Description of the making of guns at the Liege Firearms Foundry), written by U. Huguenin. This book was probably introduced in 1836, before being translated into Japanese, as the presence of Western warships demanding the opening of the country became more frequent. The Japanese wanted introduce Western iron-making technology to mold cannons and strengthen the coastal defense. However, doing practical work from the manual was not easy, as the Japanese did not have the same technical background as the Westerners. Theirs attempts were not a simple transfer in the field of metallurgy, but involved the whole technical sector around the production of guns. It was very difficult for them without any prior knowledge of bricks or drills and harboring a completely different concept of metals. Despite the traditional production of iron and bronze cannons, they had to "re-conceive" all the elements involved in the work: raw materials, construction with bricks, furnace temperature, control of melting, iron cannon casting, and so on. It was through a series of "trial and error" that they were able to assimilate these new materials and these new practices thus constituting the later basis of Japanese industry.My research is based not only on archives, but also on archaeological data. Indeed, four reverberator furnaces, having been used to melt iron, are preserved in Nirayama in Japan. It aims to show how scientific and technical concepts can be understood and appropriate from the translation of foreign texts alone

La tesis doctoral que presentamos a continuación bajo el título: “Análisis traceológico de la cerámica: modelado y espacio social durante el postalayótico (V-I A.C.) en la Península de Santa Ponça (Calvià, Mallorca) tiene una doble orientación: Por una parte es una nueva propuesta metodológica fundamentada en la reconstrucción de los sistemas de modelado por medio de la traceología cerámica. Por otro, es una aplicación metodológica sobre un conjunto de cerámicas adscritas a la edad de hierro y procedentes de diferentes yacimientos del sur de la isla de Mallorca. En este sentido, los datos e interpretaciones que aquí se exponen son deudores de una línea de investigación sobre tecnología cerámica que inició un joven equipo de investigadores de la universidad de las Islas Baleares allá por el año 1999. Se trata por tanto de una propuesta que siguiendo una línea de investigación ya consolidada en la Universidad de las islas Baleares a través del grupo de investigación arqueobalear, desarrolla un nuevo método de análisis del modelado cerámico fundamentado en la identificación de las macrotrazas de manufactura presentes en las vasijas cerámicas. Se trata de una metodología que debe enmarcarse dentro de las recientes propuestas de la arqueología francófona orientadas a identificar las técnicas y procesos de modelado a través de la traceología cerámica. En este trabajo, al igual que ocurre con otros que hemos ido publicando, se propone un modelo teórico-analítico basado en el concepto de cadena operativa en el que encuadrar la secuencia de operaciones técnicas documentadas. Sin embargo, estamos convencidos, que identificar los sistemas de fabricación no debería ser el fin último de un trabajo arqueológico. Saber cómo se fabrica una vasija no pasa de lo anecdótico si no la insertamos en su contexto y empleamos los estudios tecnológicos para inferir comportamientos sociales. Como conclusión planteamos que, el modelado, más que otras fases de la cadena operativa, está fuertemente imbricado en los procesos de aprendizaje y en las dinámicas sociales. A partir de esta premisa hemos podido establecer que la alta variabilidad en las cadenas operativas permite visualizar una fragmentación de los procesos de aprendizajes que tendría mucho que ver con la progresiva desestructuración social que sufre la sociedad indígena durante las postrimerías de la influencia púnica en la isla
The PhD thesis here presented with the title Traceological Analysis of Pottery: Modelling and Social Space during the post-Talayotic (5st-1st century BC) in Santa Ponça Peninsula (Calvià, Mallorca) (v.gr. Análisis traceológico de la cerámica: modelado y espacio social durante el postalayótico (V-I BC) in Santa Ponça Peninsula (Calvià, Mallorca)) was developed under a twofold orientation. On the one hand, it constitutes an innovative methodological proposal grounded on the reconstruction of modelling systems by means of ceramic traceology. On the other hand, this methodology is exemplified on a pottery assemblage dated to the Iron Age which was recovered in several sites in southern Mallorca. Hence, both the data and the interpretations discussed are heir to a research line on ceramic technology set up by a young research team from the University of the Balearic Islands, Arqueobalear, around 1999. The proposal follows the research line already consolidated in the aforementioned university while expanding on a new analytical method for the analysis of pottery modelling by identifying the macrotraces present on ceramic vessels. The methodology used should thus be framed on the recent proposals of French-speaking archaeology, which is interested in recording modelling techniques and processes using ceramic traceology. In this way, the research work presented here, in line with previous publications, enlarges on a theoretical-analytical model based on the concept of châine opératoire which defines the sequence of technical operations documented. However, it is further assumed that the identification of modelling systems should not be regarded the ultimate aim of an archaeological research. Knowing how a vessel was made is not more than an anecdote unless it is embedded in its social context, as technological studies should be used to infer social behaviours. Finally, it may be concluded that modelling, even more than the remaining phases of the châine opératoire, is highly imbricated in learning processes and social dynamics. From this premise, it can be stablished that the large variability detected in the châine opératoire makes visible the fragmentation of the learning processes, a fact closely related to the progressive social disintegration of the indigenous society at the close of the Punic influence on the island.

The sharing of information across government intra- and inter-agencies provides enormous benefits to Intelligence operations, but it also poses risks to Intelligence organizations’ operational capability. These benefits and risks of sharing information within Intelligence Communities introduce a paradox that disturbs decision-making abilities and affect existing and future relationships with local and national Intelligence partners. With this paradox, there exist particular forces that affect the paradox, such as organizational factors and the behavior of an information sharer, the responsible actor that decides on how, when and with whom to share the information. Combining the two can produce a positive (desired) outcome that leads to successful mission accomplishment or negative (inadvertent) outcome that leads to loss of information disclosed or intentional loss of valuable information. An inadvertent outcome could result in an impact to the national defense of the United States. Do Intelligence Analysts share information when the risks outweigh the benefits? This research examines how understanding the paradox of information sharing is a critical element in understanding the behavior of Intelligence Analysts’ decision-making in Intelligence operations.

Where are the next decade's greatest investment opportunities? Veteran investor Marko Dimitrijevic argues that they can be found in frontier markets, which account for seventy-one of the world's seventy-five fastest-growing economies and 19 percent of the world's GDP. Yet many investors ignore them. Fueled by new access to technology and information, frontier markets are emerging even faster than their predecessors, making them an essential component of a globally diversified portfolio. In Frontier Investor, Dimitrijevic shows through colorful case studies, compelling charts, and fascinating travel anecdotes that it is not only possible but prudent to invest in these unfamiliar and undervalued options. Dimitrijevic explains how frontier markets such as Nigeria, Panama, and Bangladesh are poised to follow the similar paths of Chinese, Indian, and Russian markets, which were considered exotic two decades ago. He details a strategy for how and where to invest, directly or indirectly, to profit from frontier growth. Dimitrijevic covers the risks, political and otherwise, of these markets, the megatrends that promise exciting investment opportunities in the coming years, and the prospects for countries beyond the frontier, including Myanmar, Cuba, and even Iran. Rich with experience and insight, Frontier Investor opens up a whole new world—and worldview—to investors.

AbstractSunzi said, “Warfare is pivotal to the state. [It is] a milieu where life and death are decided, [it holds] the path to survival or extermination and cannot be neglected.” In like manner, the Commentary of Zuo (Zuozhuan) states, “Rituals and warfare are of vital importance to the state.” From this we see that besides ritual matters, such as ancestor worship and maintaining the temples, rulers in ancient China considered warfare and military training to be of utmost importance. Consequently, much attention was paid to sacrificial implements and weapons of war. The production and maintenance of arms was an integral part of this effort as it impacted state security as a whole. The study of ancient arms therefore not only teaches us about ancient weaponry and methods of combat but also yields unique insights into the technology and organization of war. The principal short-range weapons during the Han dynasty were jian (double-edged sword)and dao (single-edged sword), while the latter gradually replaced the jian in military use as the dynasty wore on, partly as a result of the rise of cavalry. This paper contains three parts: iron smelting and weapon production in the Han dynasty; the ancient techniques of iron smelting in shaft furnace; and reconstructing the Han ring-pommel dao with ancient methods.

AbstractFar-right grassroot organizations were early adopters of the internet and social media and have been using it to spread their ideologies, mobilize people and network since the 1990s. With the increased usage of social media, their communication style has naturally changed. Due to the interactive nature of social media, the far-right groups started to communicate in a savvy style based on meme and DIY aesthetics. This style allows these groups to blurry the line between serious and irony (Shifman, L., Memes in Digital Culture. Massachusetts Institute of Technology, Cambridge, Massachusetts, 2014) but also between facts and misinformation (Klein, O., The Open Journal of Sociopolitical Studies 154–179, 2020). There is a burgeoning body of literature investigating the way and for what purposes such organizations use the internet in which the researchers look particularly on memes (Klein, O., The Open Journal of Sociopolitical Studies 154–179, 2020) but also humour (Billig, M., Comic racism and violence. In S. Lockyer, & M. Pickering (Eds.), Beyond a joke. The limits of humor (pp. 25–44). New York: Palgrave Macmillan, 2005a; Billig, M., Laughter and ridicule. Towards a social critique of humor. London: SAGE Publications, 2005b). However, not many studies explored the link between humour and morality. The aim of this exploratory study, in which humour is viewed as a means of claims making and negotiation of political views, is to deepen the knowledge of how humour in memes produced and reproduced by far-right organizations can serve as a tool for constructing a moral order. To do so, I analysed memes used on the far-right Facebook page run by Czech organization Angry Mothers which engage in anti-Islam and anti-gender activism. Based on Michael Billig’s (2005) distinction between rebellious and disciplinary humour, I argue that the organization used rebellious humour to present themselves as an alternative to mainstream media and resistance to the alleged dictatorship of liberal elites and disciplinary humour to put minorities (both sexual and ethnic) “in their place”.

Abstract Gelled acid systems based upon gelation of hydrochloric acid (HCl) are widely used in in both matrix acidizing and fracture acidizing treatments to prevent acidizing fluid leak-off into high permeable zones of a reservoir. The gelled up fluid system helps retard the acid reaction to allow deeper acid penetration for hydrocarbon productivity enhancement. The in-situ gelation is typically achieved by using crosslinked polymers with the acid. Conventional in-situ crosslinked gelled acid systems are made up of polyacrylamide gelling agent, iron based crosslinker and a breaker chemical in addition to other additives, with the acid as the base fluid. However, the polymer-based systems can lead to damaging the formation due to a variety of reasons including unbroken polymer residue. Additionally, the iron-based crosslinker systems can lead to scaling, precipitation and or sludge formation after the acid reacts with the formation, resulting in formation damage and lowering of hydrocarbon productivity. In this paper we showcase a new nanoparticles based gelled acid system that overcomes the inherent challenges faced by conventional in-situ crosslinked gelled acid systems. The new system can work in 5 to 20 % HCl up to 300°F. The new system does not contain any polymer or iron based crosslinker that can potentially damage the formation. It comprises nanoparticles, a gelation activator, acidizing treatment additives along with HCl. The new in-situ gelled acid system has low viscosity at surface making it easy to pump. It gels up at elevated temperatures and pH of 1 to 4, which helps with diverting the tail end acid to tighter or damaged zones of the formation. We demonstrate that the viscosification and eventual gelation of the new system can be achieved as the acid reacts with a carbonate formation and the pH rises above 1. As the acid further reacts and continues to spend there by increasing the pH beyond 4, the gel demonstrates reduction of viscosity. This assists in a better cleanup post the acidizing treatment. Various experimental techniques were used to showcase the development of the nanoparticle based acid diversion fluid. Static and dynamic gelation studies as a function of time, temperature and pH are reported. The gelation performance of the new system was evaluated at temperatures up to 300°F and discussed in the paper. Comparative performance of different types of gelation activators on the gelation profile of the nanoparticles is evaluated. It is also shown that the gelation and viscosity reduction is entirely a pH dependent phenomenon and does not require any additional breaker chemistry, and therefore provides more control over the system performance. The novelty of the new gelled acid system is that it is based upon nanoparticles making it less prone to formation damage as compared to a crosslinked polymer based system.

Abstract Gelled acid systems based upon gelation of hydrochloric acid (HCl) are extensively used in both matrix acidizing and fracture acidizing treatments to prevent acidizing fluid leak-off. The gelled-up fluid system helps retard the acid reaction to allow deeper wormhole propagation. Conventional in-situ crosslinked gelled acid systems consist of a polyacrylamide polymer, a crosslinker (such as iron-based crosslinker), a chemical breaker, other additives, along with acid. However, these systems can lead to damaging the formation due to several reasons including unbroken polymer residue or scaling, resulting in lowering of hydrocarbon productivity. To mitigate these drawbacks, we have developed a self-breaking, formation damage-free, novel nanoparticles based gelled acid system to replace the polymer based gelled acid system. The new gelled acid system is based on, surface modified nanoparticles to make them compatible in acidic environment, a gelation activator, acidizing treatment additives along with HCl to overcome the challenges the conventional systems face. The new system can work with up to 28& of HCl up to 300°F with low viscosity at surface, making it easy to be pump. As the acid spends due to reaction with the formation the pH of the fluid transitions from acidic to basic pH. The gelation phenomenon of the new system is controlled by the increasing pH. As the pH increases beyond pH 1 gelation of the nanoparticles occurs thus gelling up the acidic fluid. As the pH further continues to rise beyond pH 4 the nanoparticles lose their capability to gel up and the fluid viscosity decreases to pre-gelation level, facilitating easy post treatment flow back. A systematic experimental protocol was followed to develop the new system that is documented in this paper. It is shown that the gelation properties are pH dependent phenomenon providing the critical control over the gelation time and avoiding any premature gelation during pumping the treatment. The effectiveness of the system by not damaging the formation was investigated using regain permeability studies. The new system showed excellent regain permeability. The obtained data confirmed several advantages of the new system over conventional polymer based gelled acid systems. Gelation experiments were performed to gather a better understanding of the gelation mechanism and also to get effective control on the gelation and break properties. The uniqueness about the new system is that, it is formation damage free without the need to use polymers or iron based cross-linkers that may lead to potential damage mechanisms.

LD slag (LDS) is a major solid waste generated in huge quantities during steel making. It comes from slag formers such as burned lime/dolomite and from oxidising of silica, iron etc., while refining the iron into steel in the LD furnace. This work aims at utilization of waste LDS to develop surface coatings by plasma spraying technique. This technology has the advantage of being able to process various low-grade ore minerals to obtain value-added products and also to deposit materials, generating near homogeneous coatings with the desired microstructure. Coatings prepared for this investigation are characterized in terms of their thickness, hardness, adhesion strength and porosity. Coating deposition efficiency is calculated in order to assess the coatability of LDS and XRD is carried out in order to ascertain the various phases present in the coating. Premixing of TiO2 powder with LDS is found to substantially improve the interfacial adhesion. It is also found that the operating power levels of the plasma torch affect the adhesion strength, coating deposition efficiency and mean thickness of the coatings. This work reveals that LD slag is eminently coatable and can be gainfully used as a potential cost-effective material for deposition of plasma spray coatings on metallic substrates.

Abstract Acid systems are widely recognized by the oil and gas industry as an attractive class of fluids for the efficient stimulation of carbonate reservoirs. One of the major challenges in carbonate acidizing treatments is adjusting the convective transport of acid deep into the reservoir while achieving a minimum rock face dissolution. Conventional emulsified acids are hindered by several limitations; low stability at high temperatures, a high viscosity that limits pumping rate due to frictional losses, the potential of formation damage, and the difficulty to achieve homogenous field-scale mixing. This paper highlights the successful application of an engineered low-viscosity retarded acid system without the need for gelation by a polymer or surfactant or emulsification by diesel. An acid stimulation job using a new innovative retarded acid system has been performed in a West Kuwait field well. The proposed acid system combines the use of a strong mineral acid (i.e. hydrochloric acid "HCl") with a non-damaging retarding agent that allows deeper penetration of the live HCl acid into the formation, resulting in a more effective stimulation treatment. The retardation behavior testing includes dissolution experiments, compatibility testing, coreflood study, and corrosion rate testing (conducted at 200°F). The on-job implementation included the use of a packer to pinpoint fluid pumping (pre-flush) at the point of interest, followed by the customized novel retarded acid system for improving conductivity at perforations and effective reservoir stimulation. This acid system is characterized by having a low-viscosity and high thermal stability system that can be mixed on the fly. This approach addresses the main challenges of emulsified acid systems and offers a cost-effective solution to cover a wide range of applications in matrix acid stimulation and high-temperature conditions that require a chemically retarded acid system. The application of this novel acid retarded system is a fit-for-purpose solution to optimize the return on investment by maximizing the well production and extending the lifetime of the treatment effect. This new system also offers excellent scale inhibition and iron control properties which eliminates the need for any acid remedial work, making it an economical approach over other conventional acid systems. The paper presents results obtained after stimulating the carbonate reservoir and describes the lessons learned from the job planning and execution phases, which can be considered as a best practice for application in similar challenges in other fields. Proper candidate selection, best available placement technique, and lab-tested formulation of novel retarded acid system resulted in achieving 1700 BOPD of oil production (27% higher than expected).
