Abstract:
In vitro study of the rumen fluid (RF) and hindgut content (HC) fermentation by microbiota taken from sheep grazing in an area atmospherically polluted from the non-ferrous metal industry was conducted and compared with controls from an uncontaminated area (UA). The experimental sheep were exposed to the prolonged intake of heavy metals by grazing in the contaminated area (CA) for one year. Soil and grass from that area and the rumen content of sheep were analyzed for heavy metal levels. Based on the levels of mercury (4.752 mg/kg), copper (232.9 mg/kg), cadmium (1.167 mg/kg), lead (92.509 mg/kg) and arsenic (74.59 mg/kg) the soil was categorized as profusely contaminated. Meadow hay (MH) from UA was used as a tested substrate of fermentation activity; it was incubated with buffered RF and HC inocula from CA and UA for 24 h. The gas volume in CA was significantly decreased by 50 and 36% in RF and HC, respectively. The methane production in CA was significantly decreased by 77 and 71% in RF and HC, respectively. The significantly decreased values of the fermentation parameters in CA in comparison with UA were accompanied by the reduced (P < 0.01) total concentration of rumen ciliate protozoa.

Abstract:
We study the noise spectra and high-frequency permeability of inhomogeneous magnetic materials consisting of single-domain magnetic nanoparticles embedded into an insulating matrix. Possible mechanisms of 1/f voltage noise in phase-separated manganites is analyzed. The material is modelled by a system of small ferromagnetic metallic droplets (magnetic polarons or ferrons) in insulating antiferromagnetic or paramagnetic matrix. The electron transport is related to tunnelling of charge carriers between droplets. One of the sources of the 1/f noise in such a system stems from fluctuations of the number of droplets with extra electron. In the case of strong magnetic anisotropy, the 1/f noise can arise also due to the fluctuations of the magnetic moments of ferrons. The high frequency magnetic permeability of nanocomposite film with magnetic particles in insulating non-magnetic matrix is studied in detail. The case of strong magnetic dipole interaction and strong magnetic anisotropy of ferromagnetic granules is considered. The composite is modelled by a cubic regular array of ferromagnetic particles. The high-frequency permeability tensor components are found as a functions of frequency, temperature, ferromagnetic phase content, and magnetic anisotropy. The results demonstrate that magnetic dipole interaction leads to a shift of the resonance frequencies towards higher values, and nanocomposite film could have rather high value of magnetic permeability in the microwave range.

Abstract:
A liga de alumínio designada AA4006 é muito utilizada na indústria. É uma liga do sistema Al-Fe-Si, com teores (% em massa) de Si na faixa de 0,8 a 1,2% e Fe entre 0,5 e 0,8%. Apesar de ser bastante utilizada, ela foi pouco estudada. Neste trabalho foi realizado um estudo comparativo da microestrutura e da textura cristalográfica entre chapas da liga AA4006 produzidas por dois processos industriais de lingotamento: contínuo (Twin roll caster TRC) e semicontínuo (Direct chill DC). Para a caracterização microestrutural, foram utilizadas as técnicas de microscopia óptica com luz polarizada, microscopia eletrônica de varredura com microanálise química, medidas de condutividade elétrica e ensaios de dureza Brinell. A textura cristalográfica foi determinada por difração de raios X. Foram detectadas e discutidas diferenças significativas nas morfologias e distribuições de grãos e de partículas de fases intermetálicas. O estudo da textura cristalográfica foi realizado ao longo da espessura das tiras e os resultados mostraram variações significativas da textura entre as chapas ao longo da espessura. A chapa produzida por lingotamento contínuo apresentou uma típica textura de cisalhamento nas proximidades de sua superfície, enquanto nas regiões mais internas a fibra foi observada. O estudo da recristalização de chapas metálicas laminadas a frio é muito útil para a obtenção da temperatura de amolecimento do material submetido a um tratamento térmico. Tratamentos térmicos isócronos no intervalo de uma hora foram feitos em amostras das duas chapas e a chapa produzida pelo processo TRC apresentou a temperatura para 50% de recristalização em torno de 290 ºC e a amostra da chapa produzida pelo processo DC em torno de 270 ºC. A textura cristalográfica pode mudar com a recristalização e com a laminação do metal. Utilizando estas etapas de processamento do material, a orientação dos grãos de uma tira metálica pode ser otimizada, a fim de, por exemplo, melhorar a estampabilidade de chapas na obtenção de um dado produto com valor agregado. Neste trabalho as curvas de amolecimento para duas chapas produzidas por lingotamento contínuo e lingotamento semicontínuo da liga de alumínio AA4006 também foram determinadas e comparadas. Embora as diferenças detectadas entre as curvas de amolecimento tenham sido pequenas, foi possível verificar que a recristalização da chapa produzida por twin roll caster TRC ocorre em temperaturas mais elevadas do que na chapa produzida pelo processo direct chill DC. Resultados da textura cristalográfica em amostras destas chapas (laminadas e recozidas) foram obtidos utilizando difração de raios X e difração de elétrons retroespalhados EBSD. Estes resultados indicaram a presença da textura de cisalhamento na superfície e a fibra no centro da amostra laminada a frio (70% de redução) da chapa obtida por lingotamento contínuo. Na amostra da chapa obtida por lingotamento semicontínuo, a componente cubo e a fibra foram vistas na superfície e no centro. Uma textura fraca com grãos orientados ao acaso foi vista nas duas amostras (TRC e DC) recristalizadas das duas chapas, possivelmente, devido à nucleação estimulada por partículas. A fibra desapareceu nas amostras (TRC e DC) recristalizadas.
AA4006 Aluminum alloy is extensively used in industry. It belongs to the Al-Fe-Si system, with Si between 0,8 and 1,2 % mass, and Fe between 0,5 and 0,8 % mass. This alloy is less studied despite its extensive use. A comparative microstructural study has been performed in as-received AA4006 alloy strip produced by two industrial casting processes: twin roll caster (TRC) and direct chill (DC). Polarized optical microscopy, scanning electron microscopy with microanalysis, electrical conductivity measurements and Brinnel hardness tests have been used for microstructural characterization. Significant differences in the grain and intermetallic particle sizes, morphologies and distributions were detected and are discussed. Thermal treatments effects on the silicon content in solid solution were also studied. Crystallographic textures have been also determined. Textures across thickness of both sheets have been analyzed and compared. Results showed significant texture changes across thickness of the specimens. Texture analysis was carried out using X-ray diffraction technique. Twin roll caster (TRC) sheet presented the typical shear texture near the surface, while, in internal regions, the -fibre was observed. A recrystallization study of cold rolled metallic sheets is very important to obtain softening temperature for the material during annealing. After cold rolling with 70% of reduction in thickness, followed by isochronous heat treatments, the samples of the two sheets produced by TRC and DC presented a 50% recrystallization temperature around 290 ºC and 270 ºC, respectively. Crystallographic texture can change during the metal rolling and recrystallization. These processing steps can optimize the grain orientation distribution in a metal strip to improve, for instance, the stamping process, in order to obtain an aggregated value product. Softening curves were also compared and determined for the two sheets (rolled and annealed) of the AA4006 aluminum alloy produced by twin roll caster TRC and direct chill DC processes. It was detected that the recrystallization of the strip produced by TRC process occurs at a higher temperature than that for the DC process, despite the little differences in their softening curves. Crystallographic texture results, for the sheet samples, were obtained by using X-ray diffraction and electron back scatter diffraction EBSD techniques. These results indicated the shear texture presence on the surface and fiber at the center of the cold rolled (70% area reduction) sample for the sheet produced by TRC process. In the sheet sample produced by the DC process, under the same conditions, the cube component and fiber texture (at the surface and at the center) were observed. A texture with random oriented grains was detected in two deformed and recrystallized samples of the two sheets (TRC and DC). It is suggested that this texture occurs due to the particle stimulated nucleation. There was fiber absence in the recrystallized samples (TRC and DC).

This thesis was motivated by the study of voids and non-metallic inclusions influence on the high cycle fatigue of ferrous materials like steel, powder metal and gray cast iron. A second objective was to obtain simpler parameters, like the ones measured in hardness, static bending or axial tests, to evaluate materials in early phases of projects, in a way to avoid long fatigue tests. Initially the average fatigue strength was obtained for a high carbon steel. The effect of a silicon oxide inclusion near the surface on the performance of heavy-duty Cr-Si spring wire was also analyzed. The evaluation was done in terms of stress concentrating on the inclusion contours, due to the shot peening application on the surface and normal fluctuating loads. Mechanical properties of powder metal and cast iron were revised. Static tests without and with the presence of notches were performed, with the objective of obtaining a static notch sensitivity factor, to correlate with torsion fatigue results. The relation between hardness and torsion fatigue strength was evaluated for the cast iron, and simulations using linear elastic and nonlinear materials were performed to obtain geometric stress concentrating factors. A mesoscale simulation was done in plane stress, making it possible to evaluate local stress concentration in the cast iron matrix.
Esta tese foi motivada pelo estudo da influência de vazios e inclusões não metálicas na fadiga de alto ciclo de materiais ferrosos como aços, materiais obtidos por metalurgia do pó e ferros fundidos cinzentos. Foi objetivo também, avaliar parâmetros de medição mais simples, como os obtidos de ensaios de dureza e de flexão ou tração estáticos, como forma de avaliar materiais em fases iniciais de projeto, evitando-se longos ensaios de fadiga. Inicialmente obteve-se a resistência à fadiga de alto ciclo de um aço de alto teor de carbono. Analisou-se também o efeito da presença de uma inclusão de óxido de silício próximo à superfície de um arame de aço Cr-Si utilizado em molas submetidas a cargas reversas. A análise foi feita em termos de concentração de tensão nos contornos da inclusão, devido à aplicação de shot peening na superfície e também devido às cargas de operação. Uma revisão de propriedades mecânicas de aços obtidos por metalurgia do pó e do ferro fundido foi realizada, assim como ensaios estáticos sem e com entalhe, no intuito de obter um fator de sensibilidade ao entalhe estático, como forma de correlacionar com a sensibilidade ao entalhe na fadiga em torção. Foi avaliada a relação entre a dureza do ferro fundido e a sua resistência à fadiga na torção e realizadas simulações com material linear elástico e não linear para obter um fator de concentração de tensão geométrico. Uma simulação em mesoescala em estado plano de tensão foi realizada, podendo-se determinar a concentração de tensões locais na matriz do ferro fundido.

Abstract:
In the first part of this thesis the prices of six non-ferrous metals (aluminum, copper, lead, nickel, tin, and zinc) are used to assess the forecasting performance of GARCH models. We find that the forecasting performances of GARCH, EGARCH, and TGARCH models are similar. However, we suggest the use of the GARCH model because it is more parsimonious and has a slightly better statistical performance than the other two. In the second part, the prices of six non-ferrous metals and the price of crude oil are used to examine the dynamic links between oil and metal returns by using the BEKK specification of the multivariate GARCH model and the Granger causality-in-variance tests. Results of our study agree with the previous studies in that the crude oil market volatility leads all non-ferrous metal markets. In order to move as far away from the effects of 9/11, daily data for the period December 12, 2003 &ndash

Abstract:
The aim of this thesis has been to investigate and interpret late Iron Ageand Early Medieval traces of non-ferrous metalworking on the islandGotland, Sweden. Gotland was not, based on the archaeological record, anintegrated part of the common Scandinavian culture. Instead a local,endemic cultural expression had developed; a seclusion which lasted forcenturies despite the islands central position in the Baltic Sea. In thepast, key elements for the understanding of local settlement- and burialpractices as well as the local material culture were mainly recovered andreported by local farmers. A specific category of such finds – so-called‘bronze slag’ is discussed and partly reinterpreted in the first study ofthis thesis. Two further studies treat different aspects of metalworkingand metalworkers – one discusses common archaeological notions ofScandinavian workshops, production sites and metalworkers from a criticalperspective while the other mainly focuses on the Gotlandic finds frommetal-detector surveys carried out over the last 35 years. Based on whereand to which extent, both from a quantitative and a qualitative point ofview, these finds occur a hierarchical classification into four sub groupsis presented – ordinary farm sites with traces of non-ferrous metalworking,workshop sites, potential workshop sites and last, extrovert harboursettlements. A fourth study presents an attempt to evaluate the usefulnessof magnetometry in delimiting extant traces of high-temperature crafts,such as metalworking. The last study of the thesis presents an attempt touse trace elements analysis of skeletal lead in human bone to identifypotential non-ferrous metalworkers. As the wearing of endemic Gotlandic jewellery appears to have been centralin the manifestation of the local identity it is argued that themetalworking artisans played a crucial role in defining how this identitywas signalled and displayed via the jewellery and dress-related metalobjects. It is further suggested that these artisans might have played animportant role in upholding the local economy before the advent of localminting.

Abstract:
Розрізнення кольорових металів між собою за допомогою металоаналізаторів є дуже актуальним питанням, оскільки звичайні металошукачі не вирішують дане питання. Провівши серію дослідів, автору вдалось визначити, що інформативні параметри в сигналі металоаналізатора залежать від тривалості часової реалізації вхідного сигналу, яка, у свою чергу, залежить від швидкості проходу антени над дослідним зразком, яка повинна бути завжди однаковою. Щоб правильно набрати статистичні дані для вирішення задачі розпізнавання методом лінійного передбачення, усі отримані сигнали потрібно масштабувати таким чином, щоб вони мали однакову тривалість.

Abstract:
The thesis is focused on the theoretical description of the technology of anodizing of aluminium, magnesium, zinc and their alloys. In this work, methods for formation of oxide layers and the used chemical processes are described in detail. The experimental part of this work deals with formation of oxide layers on aluminium, magnesium and zinc of high purity under different conditions. Oxide layers of different thicknesses were created on all three experimental materials. Aluminium was anodized in a bath of 10% H2SO4, magnesium in the bath of 1 mol/dm3 NaOH, and zinc in the bath of 0.5 mol/dm3 NaOH. Processes were carried out at laboratory temperature. On the aluminium, continuous oxide layer was formed. Furthermore rule "312" was verified, that can indicatively be used for calculating the thickness of the resulting oxide layer on the aluminium. When using lower current of 0.08 and 0.2 A for magnesium anodizing, dark colored layer was created comparing to higher current of 0.5 A. More rough appearance of the oxide layer was produced with increasing voltage. Further, it was observed for magnesium that the resulting layer comprises of two sublayers. For zinc, black colored layer was created when the voltage 20 V and current from 0.4 to 0.5 A were used. In the layer, two sublayers were also observed. For lower voltage and current (0.05 A, 0.17 V), formation of the oxide layer on the zinc does not occur, but the crystallographic etching was observed.

Abstract:
Part of the WTERT effort to increase the amount of metals recovered by the U.S. Waste-to-Energy industry was a survey to determine the type of equipment used for metal recovery and the quantities of ferrous and non-ferrous metals recovered, and the distribution in percent between front- and back-end recovered metals. A questionnaire was sent to the headquarters of the three major WTE companies and fifty three WTE plants responded with data for the year 2004. As mass burn and RDF plants were examined separately, a comparison of metal recovery by means of these two technologies was possible. The ways to recover metals in the U.S. WTE industry range from only manual separation of large objects at the tipping floor at mass burn facilities, to front-end recovery at RDF plants, to metal separation from the ash at the back-end of the WTE process or at a regional metal recovery facility. Accordingly, the amounts of metals recovered range from very little to over 40.000 tons per year. Comparison of the collected with estimated averages of ferrous (5%) and non-ferrous (0.7%) metals in U.S. MSW, indicated that 48% of ferrous and 9% of non-ferrous metal input are recovered at these 53 WTE facilities every year. The remainder is landfilled and represents a revenue loss that may be as high as $160 millions per year, including the payment of tipping fees for landfilling metals. Mass burn facilities recover an average of 43% of the ferrous and 5% of the non-ferrous metals, while RDF plants recover 71% of ferrous and 30% of non-ferrous of the assumed metal input. However, the metal input in some WTEs may differ from the U.S. average because of effective metal recycling practice in the community. Analysis of the front- and back-end recovery at mass burn and RDF plants shows that the former recover only 1% of the ferrous metal at the front-end and 99% from the bottom ash. In comparison, RDF plants recover 88% of the ferrous metal at the front-end and only 12% after combustion. Mass burn plants recover 94% of the non-ferrous metal at the back end. It is interesting to note that RDF plants also recover most of their non-ferrous metals (98% of the total) at the back-end. Our analysis shows that there is room for increasing metal recovery of both ferrous and non-ferrous metals at selected mass burn facilities that presently recover less than 10% of the input ferrous metals. Non-ferrous metal recovery is very low for mass-burn and low for RDF plants. Since the value of WTE metals has increased appreciably recently, due to increased consumption in China, it is a good time to consider plant modifications that will help increase metal recovery. Some of the most likely WTEs for implementing such modifications have been identified and discussions are under way for effecting plant retrofits at some facilities. A current objective is to obtain similar data from the nearly 30 facilities that were not included in the first part of this survey. We are also trying to determine how metal recycling practice in the communities that supply various WTE facilities correlates with the metal recoveries attained by these facilities.

Abstract:
Siempelkamp Nukleartechnik GmbH has gained lots of experience from melting ferrous metals for recycling in the nuclear cycle as well as for release to general reuse. Due to the fact that the world market prices for non-ferrous metals like copper, aluminium or lead raised up in the past and will remain on a high level, recycling of low-level contaminated or activated metallic residues from nuclear decommissioning becomes more important. Based on the established technology for melting of ferrous metals in a medium frequency induction furnace, different melt treatment procedures for each kind of non-ferrous metals were developed and successfully commercially converted. Beside different procedures also different melting techniques such as crucibles, gas burners, ladles etc. are used. Approximately 340 Mg of aluminium, a large part of it with a uranium contamination, have been molten successfully and have met the release criteria of the German Radiation Protection Ordinance. The experience in copper and brass melting is based on a total mass of 200 Mg. Lead melting in a special ladle by using a gas heater results in a total of 420 Mg which could be released. The main goal of melting of non-ferrous metals is release for industrial reuse after treatment. Especially for lead, a cooperation with a German lead manufacturer also for recycling of non releasable lead is being planned.

Abstract:
Abstract For the development and quality control of highly electrically conductive coatings, a device is required by which the electric conductivity can be measured. For this purpose a handheld device for measuring the electric conductivity of nonferrous metals in a nondestructive manner was tested. The measurement principle is based on an eddy current sensor which allows determining the electric conductivity within seconds. The method fulfills the demands for using it in the environment of a job shop for thermal spraying. Coatings applied with different thermal spraying methods like cold gas, HVOF, electric arc or flame spraying have been examined. Thus, it will be presented a comparison of the electric conductivity dependent on different spraying methods. Additionally, important edge conditions for spraying and measuring the conductivity of highly electrically conductive coatings like the influence of the oxygen content of the powder, the minimal coating thickness measurable with the device and the influence of the surface roughness onto the measurement were analyzed.

Abstract:
The Integrated Waste Services Association (IWSA) compiles annual data of metal recovery by U.S. waste-to-energy (WTE) facilities. The 2004 IWSA survey showed that the U.S. WTEs processed 28.8 million short tons of municipal solid wastes (MSW) and recovered a total of approximately 706,000 tons of ferrous metal scrap, i.e. 2.45% of the MSW stream. The 2001 U.S.E.P.A. report on the characterization of the U.S. wastes reported that MSW contained 7.9% metals. However, some of this metal is collected separately at the household level and a small amount is non-ferrous metal. If it is assumed that the waste stream that is “disposed” in WTE facilities contains on the average 5% of ferrous metals, the ferrous input to all U.S. WTEs is estimated at approximately 1.44 million tons. On this basis, close to 0.7 million tons of metal are not recovered in WTEs. On the same basis, the ferrous metal lost in MSW that is landfilled (247 million tons in the U.S.) is estimated to be about 12 million tons per year. The non-recovered metal at WTEs entails both environmental and economic penalties. Therefore, an industry-university collaborative study is addressed to examining a) current metal recovery before and after combustion; b) potential for increasing metal value by physical processing of the metals recovered, either at WTEs or at a regional facility to be supplied by several WTEs; c) sampling and characterization procedures used in the WTE industry; and d) potential for physical and chemical characterization of different grades of WTE metal scrap. This paper focuses on the first two subjects — the current state of WTE metal recovery and the potential for increasing metal recovery. This work in progress is published in the NAWTEC 14 Proceedings with the objective of stimulating discussion and obtaining useful input from industry and academia concerned with the conservation of non-renewable resources.

The results of the integrated study of metal waste from Almalyk Mining-Metallurgical Plant (AMMP) are reported. Non-ferrous, noble and rare-metal reserves in waste from the dressing and metallurgical conversion of copper-molybdenum and lead-zinc deposits were evaluated. Analysis of the chemical composition and distribution of non-ferrous, noble, rare and toxic metals and their mode of occurrence in artificial waste from AMMP has shown that they are highly complex ores which could be used to increase metal production at AMMP.

Abstract:
Broward County (the County), which is located on the southeast coast of Florida, is currently faced with an ash management and metals recovery decision. The County has two mass burn resource recovery plants and they process a combined total of approximately 1.65 million tons of MSW. The ash residue from these two facilities is currently landfilled. At one facility, the South Broward Waste-to-Energy Facility (the South County Facility), ferrous was being recovered at the ash monofill using mobile equipment, as the plant was not equipped with metals recovery equipment. But as market prices dropped, so did the ferrous metals recovery. This has adversely affected the useful life of the ash monofill, owned by the County. The County is looking for a cost–effective alternative for an on–line metals (ferrous and non–ferrous) recovery system.

Abstract:
Population growth, increasing prosperity and changing consumer habits globally are increasing demand for consumer electronics. Further to this, rapid changes in technology, falling prices and consumer appetite for better products have exacerbated e-waste management challenges and seen millions of tons of electronic devices become obsolete. This rapid literature review collates evidence from academic, policy focussed and grey literature on e-waste management in Africa. This report provides an overview of constitutes e-waste, the environmental and health impacts of e-waste, of the barriers to effective e-waste management, the opportunities associated with effective e-waste management and of the limited literature available that estimate future volumes of e-waste. Africa generated a total of 2.9 million Mt of e-waste, or 2.5 kg per capita, the lowest regional rate in the world. Africa’s e-waste is the product of Local and imported Sources of Used Electronic and Electrical Equipment (UEEE). Challenges in e-waste management in Africa are exacerbated by a lack of awareness, environmental legislation and limited financial resources. Proper disposal of e-waste requires training and investment in recycling and management technology as improper processing can have severe environmental and health effects. In Africa, thirteen countries have been identified as having a national e-waste legislation/policy.. The main barriers to effective e-waste management include: Insufficient legislative frameworks and government agencies’ lack of capacity to enforce regulations, Infrastructure, Operating standards and transparency, illegal imports, Security, Data gaps, Trust, Informality and Costs. Aspirations associated with energy transition and net zero are laudable, products associated with these goals can become major contributors to the e-waste challenge. The necessary wind turbines, solar panels, electric car batteries, and other "green" technologies require vast amounts of resources. Further to this, at the end of their lifetime, they can pose environmental hazards. An example of e-waste associated with energy transitions can be gleaned from the solar power sector. Different types of solar power cells need to undergo different treatments (mechanical, thermal, chemical) depending on type to recover the valuable metals contained. Similar issues apply to waste associated with other energy transition technologies. Although e-waste contains toxic and hazardous metals such as barium and mercury among others, it also contains non-ferrous metals such as copper, aluminium and precious metals such as gold and copper, which if recycled could have a value exceeding 55 billion euros. There thus exists an opportunity to convert existing e-waste challenges into an economic opportunity.
