Abstract:

While it is generally agreed that family time nourishes the young, gives purpose to those in middle years and accompanies the elders, the reality is that family time competes with contemporary social trends such as increased use of social media, the reality of dispersed families, or contends with the need or wish of caregivers to work outside the home; all of which create a life-in-the-fast-lane pace of living. However, “hearth-time”, as a metaphor for a warm place to arrive at and feel a sense of belonging, is alive with potential in Aotearoa New Zealand. This paper aims to identify and highlight the potentials that support the benefits of the hearth and time spent together and, by reviewing the origins and purpose of the hearth, build awareness of already existing hearth potentials; including our consulting rooms and the hearth-tending dynamics that abide within. To support the notion that hearth and subsequent primacy of heartfelt experiences needs more centrality in our homes, communities and even our thinking, I will draw on and extrapolate from the Greek myth of Hestia, Virgin Goddess of the hearth, drawing parallels between the principles of the myth and the value our profession and cultures offer.

Abstract:

The image of the aged parent or grandparent sitting contentedly before the hearth is a canonical trope in Victorian visual culture. The freside was, at that time, a signifcant center of the home and family, and older members of the household were viewed as principal organizing forces around this central gathering place. This article examines the archetypal image of the senescent hearthside fgure in order to better evaluate the larger context in which Victorian aging was visually interpreted and generally understood. By examining depictions of this theme by the popular British painters Walter Dendy Sadler and Frederick Daniel Hardy, this study demonstrates some ways in which art history may proft from age studies in formulating expanded readings of such material.

Abstract:

At the Pushkari I Upper Paleolithic settlement three settlement complexes with dwellings, activity areas, and hearths have been excavated. All eight hearth of the Pushkari I site located in different parts of the cultural horizon are however territorially close to each other and identical as to their geological and cultural attribution. A comparative analysis of the hearths was aimed on reconstruction of ways of their construction and using. The study was based on a simple indication of the location of hearths found on three part of the settlement (Excavations II, V and VII) —outside and inside dwellings. As a result of the study, three groups of hearth structures, which were used in different ways, were identified. The most important feature of the “outdoor” hearths is numerous pits and depressions at their base. Investigating their shape, carbonaceous bone remains, and ethnogra- phic examples, we concluded that the large outdoor hearths were used as cooking areas. Meat could be fried on bones inserted vertically into the hearths. In some cases the hearths could be the centers of working activity areas (Excavation V). The hearths inside the dwellings were small in size and were surrounded by a number of specially working activity areas. These hearths were primarily used for dwelling heating (Excavations II and V). They could also carry some economic functions. The hearth inside the dwelling (Excavation VII) has all the characteristics of an external “kitchen” hearth, but also it had a secondary carbonaceous filling brought from outside. Such a hearth structure could be a heating and kitchen object in a special-purpose dwelling.

Abstract:

The campaign life of a blast furnace is largely limited by the erosion state of its hearth section. Therefore, the study of hearth erosion is important for blast furnace ironmaking. In this study, the hearth erosion of the WISCO No. 1 blast furnace was investigated in combination with the numerical analysis of the iron flow and heat transfer in the hearth. The distributions of the wall shear stress and the temperature in the hearth were simulated and the hearth sections with high erosion risk were discussed. The hearth lining with higher shear stress is generally located near the taphole region and the 1423 K isotherm is totally located inside the hearth lining structure, with a deeper position in the central part of the hearth bottom. Based on the measurement data from the hearth damage investigation, the erosion state of the hearth bottom and the lower part of the hearth sidewall is more serious. The erosion line at the hearth bottom showed a typical “pot-bottom” shaped contour and for the hearth corner section, the average erosion depth was about 1/3 of the total wall thickness. The empirical expressions between the hearth erosion depth and the wall shear stress and the temperature were established. Moreover, the effects of key iron tapping factors on the wall shear stress and the effect of the hearth’s refractory structure on the heat transfer in the hearth are respectively discussed, aiming to provide more suggestions for hearth protection.

Abstract:

Abstract Close parallels of plot and language show that in the construction of his third Christmas book, The Cricket on the Hearth, Dickens drew directly and heavily on Chaucer's Merchant's Tale. The Merchant's Tale comically displays the ill-fated marriage between old Januarie and young May. Cricket's plot revolves around whether it is possible for young Mary Peerybingle to be happy in her marriage to the older John, even as her friend May prepares to wed the still older Tackleton. Perhaps one of the qualities that attracted Dickens to Chaucer was a shared aesthetic that mixes pathos, comedy, and social observation. Be that as it may, Dickens was sufficiently pleased by his artistic success in Cricket that he adapted the scenario of a young wife who loves her aging husband in the Dr. and Mrs. Strong subplot in David Copperfield.

Abstract:

The blast furnace (BF) hearth is critical for determining the life of a BF. Irreversibly eroded hearths can be caused by high-temperature molten iron erosion, alkali metal corrosion, and thermal stress. When serious depression erosion occurs in the hearth, furnace protection measures can prevent the erosion from expanding and ensure the safe operation of the BF. At present, furnace protection measures and furnace protection strength are mostly selected based on engineering experience. In this paper, a three-dimensional (3D) computational fluid dynamics (CFD) numerical model of BF hearth with elephant-type depression erosion was established to predict and evaluate the effect of furnace protection measures. At the same time, the phase change behavior of hot iron solidification was also considered. A numerical model was used to analyze common furnace protection measures such as increasing furnace hearth cooling, closing the tuyere, reducing the tapping productivity, and reducing the tapping temperature. The calculation results are consistent with actual furnace protection experience.

Abstract:

Charcoal production associated with the iron industry had a pervasive influence on forests during the 17th and 18th centuries in the mid-Atlantic region of the eastern United States. In a recent study we reported the altered forest composition and soil properties on historic charcoal hearths in southeastern Pennsylvania. In this study, additional experimental results describe potential past and present mechanisms that may inhibit forest development. Nyssasylvatica Marsh, wood samples taken from the first 15 years of growth on hearth sites contained roughly half the amount of P and Mn and nearly double the amount of K and Na relative to wood produced on nonhearth sites in the same period, consistent with initial pH elevation following hearth abandonment in 1883. In the greenhouse, Quercusalba L. and Quercusrubra L. showed a significant growth depression in hearth soil. When the proportion of charcoal soil varied from 0 to 100%, several growth parameters of Q. rubra declined significantly with increasing charcoal soil content. In situ foliar nutrient concentrations of Vacciniumcorymbosum L. and Quercusvelutina Lam. were significantly different in P, K, Ca, Mg, Mn, Fe, Na, and Cu on hearth versus nonhearth plots. The present inhibition of hearth regeneration appears to be the result of persistent differences in soil nutrient availability after more than a century.

Abstract:

This paper details the steps to design and implement a positive deviance-informed, “Hearth” approach for the nutritional rehabilitation of malnourished children in the district of Leogane, Haiti. Groups of four to five children met daily for two weeks at the home of a local volunteer mother for nutritional and health messages and a well-balanced meal. Health messages and meal components were determined using information gathered from interviews with the mothers of positive deviant children in the community who are well nourished despite their family's limited economic resources. Hearth participants were then followed for six months in their own home by the program “monitrices,” women hired from each village and intensively trained to supervise the Hearth program, periodically weigh the children to evaluate their progress, and liaise between the hospital and the community. Monitoring from the first cycle indicated that 100% of children in eight villages and 66% of children in the remaining five villages continued to gain weight as fast or faster than the international standard median six months after participating in a Hearth program. At the conclusion of this cycle, programmers interviewed participant and non-participant families and made six modifications to the model, including the addition of a microcredit option for participating mothers.

Abstract:

The wear of a blast furnace hearth and the hearth inner profile are highly dependent on the liquid iron flow pattern, refractory temperatures, and temperature distributions at the hot face. In this paper, the detailed methodology is presented along with the examples of hearth inner profile predictions. A new methodology along with new algorithms is proposed to calculate the hearth erosion and its inner profile. The methodology is to estimate the hearth primary inner profile based on 1D heat transfer and to compute the hot-face temperature using the 3D CFD hearth model according to the 1D preestimated and reestimated profiles. After the hot-face temperatures are converged, the hot-face positions are refined by a new algorithm, which is based on the difference between the calculated and measured results, for the 3D computational fluid dynamics (CFD) hearth model further computations, until the calculated temperatures well agree with those measured by the thermocouples.

Abstract:

Bonfire became the earliest form in shaping space when people gathered around the fire. It was stated by Vitruvius and developed by many theoretician of architecture. Nowadays, the role of fire to the space (architecture) lessened and even disappeared along with technology development. Contrarily, the phenomenon in Tengger showed different result. The presence of hearth (pawon) in Tenggerese house became stronger. It could be seen from the increasing number of hearth there.This research shows, there was a close connection between society structure along with time factor and the number of hearth along with its use in Tenggerese house. The number of hearth in a house could be increased if the number of family members were increased as well. It is possible that the segmentation of hearth space in Tenggerese house could be affected by the influence of the number of family members to the changes of hearth. This possibility would be explored in the research. Interpretive-Historic research method was used in the research to explore the phenomenon found in the field. By exploring field data and historical data, it was finally shown the influence of the changes number in family members to the segmentation of hearth space in Tenggerese house, particularly those related to the marriage and mortality. Space segmentation, especially segmentation of the hearth space in Tengger successfully demonstrated a close link with the change in the numbers of family members.

Abstract:

The wetland site of Verrebroek “Dok” situated in northern Belgium is one of the largest and best dated locations of Mesolithic material in northwestern Europe. Salvage excavations organized since 1992 at this large, unstratified open-air settlement have revealed more than 50 spatially independent artifact concentrations with traces of numerous fireplaces. Single entity dating of charred hazelnut shells from surface-hearths and charcoal from hearth-pits was used to obtain information not only on the sites duration, but also on the relation between the surface hearths and the hearth-pits. The dates were also used to look at discrepancies between the radiocarbon chronology and the typo-chronology of the lithic artifacts.

Abstract:

A Positive Deviance (PD) Hearth intervention is a home and neighborhood-based nutrition program for children who are at risk for protein-energy malnutrition in a low resource community. The intervention uses the ‘Positive Deviance’ approach to identify those behaviors practiced by the mothers or caretakers of well-nourished children from poor families and transfers such positive practices to other mothers who are equally disadvantaged economically. Positive Deviance Hearth intervention is designed to treat malnourished children, enable the families to sustain their rehabilitation at home on their own and to prevent malnutrition in younger siblings. However, PD Hearth intervention monitoring system in Migori only assesses a program’s ability to treat, one of the three PD Hearth objectives. Thus, there was need for impact evaluation to measure outcomes of the PD Hearth intervention to sustain rehabilitation and prevent malnutrition in younger siblings. The objectives of the study were to determine the level to which PD Hearth enables families to sustain rehabilitation at home on their own and to identify the practices which influence PD Hearth outcomes. The study was designed as a pipeline quasi-experimental and mixed method was used to collect data and perform statistical analyses. Single stage cluster sampling was used to identify 53 and 54 children on the intervention and comparison group in five communities. Weight measurements of the children on the intervention aged 6 to 59 months at the entry, exit and graduation stages were retrieved from Kenya Medical Research Institute Family AIDS Care and Education Services programme activities reports. Anthropometry (height measurements) for the children on the intervention and comparison children was taken. Caregivers filled in a questionnaire, assisted by the researchers as necessary. At entry, 18.9% children on the intervention had moderate underweight while 43.4% had mild underweight. At current status though, 3.8% and 34.0% had moderate and mild underweight respectively. The regression model predicted that Weight-for-Height (WAZ) of the children on the intervention at current status lied on 51.5 percentile, thus, normal for underweight. Increased feeding frequency made the largest contribution to weight gain than other caregiver practices. Therefore, the Migori County government in collaboration with the Ministry of Health needs to scale up PD Hearth intervention to reverse cases of Moderate Acute Malnutrition (MAM) and prevent Severe Acute Malnutrition (SAM) in the County.

Abstract:

The materials’ properties in the hearth of the blast furnace are very crucial for the hearth conditions. In this study, a number of coke, slag, metal, and aggregate samples were collected from the hearth of the LKAB’s experimental blast furnace (EBF). Subsequently, the coke, slag, and metal samples were chemically analyzed by X-ray fluorescence (XRF) or optical emission spectrometer (OES); the aggregate samples were analyzed by scanning electron microscope combined with energy-dispersive X-ray spectroscopy (SEM/EDS). The possible flow field of the liquid in the EBF hearth before quenching is depicted according to Cu tracers in the metal samples. Selected elements in the coke, slag, and metal were mapped for two sampling layers in the hearth, as well as in one cross section of the flow field. The results indicate that there exists an area beneath, and in front of, tuyere 3, where the flow resistance of the liquid was high. The high flow resistance contributed to the formation of a cold zone in the close-to-wall region and at the bottom of the EBF hearth. The temperature distribution in the EBF hearth has significant impacts on the chemical properties of the materials in different positions of the EBF hearth, as well as on the radial and vertical distributions of certain elements/components.

Abstract:

Stable blast furnace operation requires proper drainage of liquid from the hearth. The estimation of drainage rate and hearth liquid level are of utmost importance for understanding the underlying hearth phenomena. The present review gives an insight of the need for measurement of the hearth liquid level and further throws light on various methods of estimation of hearth liquid level in-depth, which is primarily divided into 2 categories namely; model-based estimation and sensor-based estimation. Although the model-based estimation and sensor-based estimation have their own advantages and disadvantages, an integrated system comprising of both methods could potentially facilitate operators to reveal the state of hearth, which is unless not available with the implementation of a single method of estimation. Furthermore, the challenges in the estimation and the prospects for determining the reliable hearth liquid level measurement in blast furnace are discussed. The article is presented to give prospect of encountering the drift occurring in estimation of liquid level, which leads to inaccurate prediction and simulation with the industrial blast furnace. Lastly, the article gives recommendation for improving the liquid level estimation methods in blast furnace.

Abstract:

Abstract This article offers a methodological approach to study hearth features in general. The hearths of the Palaeo-Eskimo tradition are often well preserved, which makes it possible to interpret which heating processes took place, and their effects on the indoor climate of the dwelling. To obtain this type of information, recording of fire-cracked rocks within and in connection to hearths is of special importance. The Palaeo-Eskimos made use of a versatile pyro-technology, adjustable to the most extreme conditions in areas where access to firewood was limited. An archaeological experiment in combination with calculations of hypothetical combustion of fat shows that it was possible for the Independence I people to live through the High Arctic winter in tents with a reasonable degree of comfort. Also, the symbolic aspects of hearths are discussed.

Abstract:

The distribution function of temperature in blast furnace satisfies a series of equations. The location and shape of hearth erosion line of blast furnace can be calculated by the data from thermocouple. We use the method of perturbation solution to solve the inverse problem and estimated the error by using related mathematical theories.

Abstract:

Research into the Bronze Age on the south-eastern Iberian Peninsula has always occupied a pre-eminent position in the archaeological discipline. Although we can state that there is a certain degree of scientific unity regarding the main cultural features of that period, few studies have focused on the social and technological process involved in the manufacture of pottery vessels. This paper aims to remedy that situation. To do this, we provide the results obtained from the technical analysis of the pottery vessels used in two activities essential to human survival – food storage and processing – in the Bronze Age settlement of Peñalosa (2086–1450 cal BC). At the same time, the macroscopic identification of the technological patterns developed in the tasks of manufacturing earthenware jars and pots allows us to reflect on the significance of the concept of specialization in the Argar Culture.

Abstract:

The erosion of the blast furnace hearth has become one of the key factors affecting the life of the blast furnace, because of the limited on-line monitoring and control means in the blast furnace hearth area, the burn-through accidents of the blast furnace hearth and bottom occur occasionally. In this work, based on the self-built platform of heat flow regulation, the control mechanism of the high melting phases of TiC is studied. The on-line control mechanism of the hearth erosion by adding titanium-containing materials was discussed. There are three steps for the on-line control of iromaking using titanium-containing materials in blast furnace. Firstly, Ti(C, N) precipitated from the molten iron due to the decrease of temperature in the erosion zone of the hearth. Secondly, the viscosity of the molten iron increased with the precipitation of Ti(C, N) in the erosional cryogenic zone and temperature further decreasing. Finally, the protective layer, included pig iron matrix and Ti(C, N) solid fulcrum, formed because of the solidification of the molten iron. The protective layer can replace the corroded lining of the blast furnace to prevent its hearth from being eroded.
