Den här uppsatsen undersöker om karaktärerna i Comviqs populära reklamföljetong om kioskägaren Karim utsatts för någon form av reduktion och/eller stereotypisering baserad på etnicitet. Med en teoretisk ansats från verk av erkända forskare som studerat stereotyper, representation, svensk film och media bland annat, har det empiriska materialet, reklamföljetongen, analyserats enligt den semiotiska traditionen. Materialet tolkas och diskuterats med stöd i den teoretiska ansatsen, med syfte att avslöja eventuell negativ missrepresentation av etniciteter. Uppsatsen avser också att diskutera vad framställningen av karaktärerna skulle kunna ha för effekt på diverse etniska grupper i samhället. Resultatet av undersökningen landade i att en viss grad av stereotyp framställning försiggår, men att det slutgiltiga budskapet som förs fram har en positiv och antirasistisk klang.

I denna studie undersöker vi utifrån ett lärarperspektiv islamundervisningen på tre kommunala grundskolor, i en mångkulturell stad, Landskrona. Studiens fokus ligger vid att undersöka om ett ”vi” och ”dem” tänkande präglas i undervisningen om islam. Den utvalda metoden är semistrukturerade intervjuer med sex grundskolelärare, vilka är verksamma på tre olika skolor. Eftersom att media idag är en viktig informationskälla, som bidrar till att forma uppfattningar har studien även behandlat hur media tillämpas i islamundervisningen. Efter de genomförda intervjuerna har lärarna indikerat att media framförallt är den källa som kan ge en kontroversiell bild av islam. Vidare framkom det i studien att samtliga intervjuade lärare på ett varierande sätt upplevt en ”vi” och ”dem” känsla i såväl skolan som islamundervisningen. De intervjuade religionslärarna hävdar dessutom att religionen har en väsentlig roll i skapandet av ”vi” och ”dem”. Detta eftersom religionen förknippas med ens identitet, enligt de intervjuade lärarna.

The popularity of using UAV in image-taking for the production of 3D models and orthophotos has increased over time. Karlskoga Municipality has recently acquired an UAV to produce their own 3D models and orthophotos. This project paper aims to study the geospatial accuracy of the orthophotos and DEM files produced using the images taken with their UAV. The flight takes only a few minutes but a considerable time is spent in the production processes. Difficulty is experienced in determining the right center point for most GCPs. Produced orthophotos in the software Photoscan have a resolution from 1.7 to 2.4 centimeters while DEM files have a resolution from 3.4 to 4.8 centimeters. Four orthophotos and four DEM files are produced where GCPs are used and not used and at two different flight heights, 76 and 105 meters. The spatial data of the ten GCPs are identified on the orthophotos and DEM files in ArcMap and compared with GNSS NRTK measurements and Lantmäteriet's data. A visual control in terms of completeness of data, alignment, residual tilt and scale is also done. Standard deviations in plane for orthophotos there GCPs are not used are greater than 2 meters, while there GCPs are used are around 0.7 meters. Standard deviations for DEM files are observed at 0.8 meters.

The main focus of the thesis is the reconstruction of 3D models and digital elevation models of five abandoned splash dams in Roklanský brook catchment using UAV photogrammetry methods. The aim of this work is to compare accuracy of the models with available conventional data sources and historical sources. Parallel topic is the research of accuracy of the models created through UAV methods and application of retention potential of small water reservoirs, in headwater areas. The images were taken with a drone-mounted camera. Modelling was done by processing images in software Agisoft PhotoScan through a workflow process, dense point cloud classification and subsequent DEM interpolation. Subsequent delineation of reservoirs retention space, altimetry correction and bathymetric analysis was performed in ArcMap over the interpolated DEM. The results and discussion point to the benefits and limitations of UAV methods, especially to altimetric accuracy of the resulting models relative to conventional DMR5G data and bathymetric characteristics derived from the models.

A dissertation submitted to the Faculty of Science, University of the Witwatersrand Johannesburg in partial fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2013. / Artisanal and small-scale mining (ASM) has been a crucial industry in Africa for centuries. In Burkina Faso approximately 95 kms northeast of the capital city Ouagadougou near the village of Dem and on a ferricrete capped ridge to the west of the village, it is possible to find a number of opencast workings and underground mines that show evidence of extensive artisanal mining for iron. Iron mining worked quartz-vein hosted and lateritic ore. Nearby, waste piles, processing sites and at least eleven (11) Bloomery furnaces are exposed on the alluvial plain. Petrographically the ore bearing rocks consist of goethite-hematite as the dominant oxides with silica. Geological and ethnographic studies conducted in 2011 focussed on detailing and mapping the mine site and host rocks (including ore rocks), and establishing the age of mining, processing and forging of ore. Selected charcoal samples were collected from furnaces sites. Limited AMS radiocarbon dating of six (6) samples was performed at Beta Analytic laboratory in Miami, Florida, USA and suggested that iron forging may have begun in the 15th century, which could also be the age of mining and processing of ore. The site has characteristics such as impure slag, eleven (11) large furnaces, hundreds of tuyeres, and crucibles, and clay fragments. Remnant slag samples were collected for petrographic and mineralogical study to deduce the mineral composition of the slag. The slag samples contained high concentration of fayalite, quartz, magnetite and hematite and low concentration of iron metal and ulvospinel suggesting an iron silicate slag of low melt temperature was formed in the furnaces.

M?todos: O presente estudo objetivou tra?ar os fatores indicativos de risco de quedas em idosos com dem?ncia irrevers?vel. Trata-se de um estudo transversal, em uma amostra de 100 idosos (60 anos), com diagn?stico m?dico de dem?ncia irrevers?vel comprovados por exame de imagem e Mini Exame do Estado Mental. A avalia??o de equil?brio foi avaliada atrav?s do Teste de Equil?brio de Berg e Timed Up and Go. Resultados: O presente trabalho mostra uma consider?vel preval?ncia da necessidade de cuidados para evitar quedas na popula??o idosa com dem?ncia irrevers?vel, pelo significante risco de quedas progressivo com o resultado da baixa pontua??o no Mini Exame de Estado Mental. Pacientes com maior depend?ncia para suas atividades de vida di?ria apresentam maior risco de quedas que as com independ?ncia parcial e do que as independentes respectivamente. O avan?ar da idade representa aumento de riscos de acidentes ocasionais assim como ser hipertenso. Ter sido um caidor no ?ltimo ano ? um fator contribuinte para recidivas. A escolaridade, dislipidemia, diabete mellitus e dorm?ncias ou parestesias em membros superiores ou inferiores, ?ndice de Massa Corporal, dor, sexo, peso, altura e circunfer?ncia abominal, n?mero de medica??es, tabagismo foram fatores que n?o interferiram no risco de quedas em nosso estudo. Conclus?o: A interpreta??o dos resultados encontrados permite sugerir que, em indiv?duos com dem?ncia irrevers?vel, medidas de preven??o, prote??o e reabilita??o devem incluir estimula??o motora e cognitiva principalmente com exerc?cios rotacionais por ser seu maior d?ficit em rela??o ao equil?brio e ao risco de quedas. Al?m disso, manter o idoso com dem?ncia irrevers?vel o mais independente poss?vel contribui para diminuir sua chance de cair. Os achados deste estudo contribuem para estimular outros estudos que visem a analisar os mecanismos pelos quais o decl?nio cognitivo e o n?vel de capacidade f?sica, interfere no risco de quedas.

Each year, millions of tons of non-ferrous scrap metal are discarded in the US. This metal is wasted due to a lack of proper recovery methods. Recent developments in spectroscopic technology have made it possible to identify the waste composition of scrap metal in real-time. This has opened the door for high-speed automated metal sortation and recovery, especially for the recovery of high value precious metals, such as titanium, nickel, cobalt, molybdenum and tantalum. Automated sortation systems typically consist of three main phases: (i) Feeding of material, (ii) Composition identification, and (iii) Physical separation. Due to their low volume and industry fragmentation, high-strength precious metal chips usually come in the form of chips smaller than 10 mm. Therefore it is extremely difficult to feed metal chips individually into the sorting system. At CR3, a new feeding mechanism was invented and developed in order to provide single layer feeding of small metal chips. A laboratory-scale prototype was built and proven to be feasible, scalable and reliable. A model was developed to predict the output of feeding variables based on initial input parameters. An operation window of the process was also defined for various metal chip resources. These will be presented, reviewed and discussed in the following paper.

However, still remains open understanding of the psychological and behavioral changes that characterize each stage of cognitive decline. This study aimed to evaluate each SCPD present in the Neuropsychiatric Inventory (NPI) in elderly patients with mild cognitive decline, mild and moderate dementia, and relate to gender, age, educational level and degree of cognitive decline. Methods: Cross-sectional descriptive and analytical study with retrospective data collection of 123 elderly from Pontifical Catholic University of Rio Grande does Sul (PUC-RS). Data were collected from medical records of patients submit the following completed instruments: (i) Cognitive Examination Addenbrooke (ACE-R); (ii) Clinical Staging of Dementia (CDR); (iii) the Neuropsychiatric Inventory (NPI). The description of variables was being conduct using frequencies, means and standard deviations. The association between categorical variables (gender, education, age and CDR) and the presence of behavioral and psychological symptoms will be analyzed. P values ? 0.05 will be considered significant. In assessing the association of the BPSD with sex, apathy showed a significant association (p = 0.027) in 44.4% of men and eating disorders (p = 0.019). The association of the BPSD and age, delusions corresponded to 13.3% in the age group of 60 to 69 years, 9.4% between 70 and 79 years and 32.5% after 80 years of age (p = 0.024). Depression was present in 66.7% of individuals between 60 to 69 years, 52.8% between 70-79 years and 42.5% in octogenarians (p = 0.047). In the association of the BPSD with education, delusions were present in 23.7% of the population illiterate or with up to 3 years of schooling, 11.4% between 4 and 7 years of study, no cases above 80 years of age (p = 0.021). Anxiety showed 32.9% in illiterate individuals or up to 3 years of study, 54.3% in those aged 4 to 7 years of study and 58.3% when above 8 years of study (p = 0.020). The euphoria was not present in illiterate and showed values of 8.6% in those with 4-7 years of schooling and 8.3% over 8 years of education (p = 0.019). By analyzing the association of the BPSD in relation to cognitive decline, delusions presented significant data with 5.0% in mild cognitive decline, 18.2% in mild dementia and 35.7% in moderate dementia (p = 0.001). Hallucinations represented 7.5% of the cases of mild cognitive decline, 21.8% in cases of mild dementia and mild dementia in 28.6% (p = 0.024). Apathy was 15% in mild cognitive decline, 32.7% in mild dementia and 35.7% in moderate dementia (p = 0.046). The disinhibition showed 5.0% in mild cognitive decline, 12.7% in mild dementia and 21.4% in moderate dementia (p = 0.042).Neuropsychiatric symptoms are common in individuals with dementia and tend to increase the prevalence over time of disease progression. The results are consistent with the literature, where the low education is a contributing factor for psychotic symptoms when faced with high education, which is protective for the existence of cognitive decline and its associated symptoms. The increase in years of life contributes to the emergence of BPSD at older ages, as octogenarians, age at which the disease can be in the moderate stage. The evaluation of SCDP at level or evidence, it must be performed in all patients. / Os sintomas comportamentais e psicol?gicos das dem?ncias (SCPD), tem sido uma preocupa??o entre os servi?os de sa?de mental, devido ao alto ?ndice de preju?zo na funcionalidade e qualidade de vida desta popula??o. Contudo, ainda permanece em aberto a compreens?o das altera??es psicol?gicas e de comportamento que caracterizam cada est?gio do decl?nio cognitivo. O presente trabalho teve como objetivo avaliar cada SCPD presente no Invent?rio neuropsiqui?trico (NPI) em idosos com decl?nio cognitivo leve, dem?ncia leve e dem?ncia moderada, e relacionar com sexo, faixa et?ria, escolaridade e grau de decl?nio cognitivo. M?todo: Estudo transversal, descritivo e anal?tico, com an?lise de dados retrospectiva. Os dados foram coletados de 123 prontu?rios de idosos do Ambulat?rio de Envelhecimento Cerebral da Pontif?cia Universidade Cat?lica do Rio Grande do Sul, que apresentassem os seguintes instrumentos preenchidos: (i) Exame Cognitivo de Addenbrooke (ACE-R); (ii) Estadiamento Cl?nico da Dem?ncia (CDR) e o (iii) Invent?rio Neuropsiqui?trico (NPI). Na descri??o das vari?veis foram utilizados frequ?ncias, m?dias e desvios padr?es. Foram analisadas as associa??es entre as vari?veis categ?ricas (sexo, escolaridade, faixa et?ria e CDR) e a presen?a dos sintomas comportamentais e psicol?gicos e considerados significativos valores para p ? 0,05. Na avalia??o da associa??o dos SCPD com sexo, a apatia apresentou associa??o significativa (p=0,027) em 44,4% dos homens bem como os dist?rbios alimentares (p=0,019). Quando avaliada a associa??o entre sintomas comportamentais e faixa et?ria, os del?rios corresponderam a 13,3% na faixa et?ria de 60 a 69 anos, 9,4% entre 70 e 79 anos e 32,5% ap?s 80 anos de idade (p=0,024). A depress?o estava presente em 66,7% dos indiv?duos entre os 60 a 69 anos, 52,8% entre 70 a 79 anos e 42,5% nos octogen?rios (p=0,047). Na associa??o entre sintomas comportamentais ou psicol?gicos com escolaridade, os del?rios estavam presentes em 23,7% na popula??o de analfabetos ou com at? 3 anos de escolaridade, em 11,4% entre 4 e 7 anos de estudo, sem nenhum caso acima dos 80 anos de idade (p=0,021). A ansiedade apresentou 32,9% nos indiv?duos analfabetos ou com at? 3 anos de estudo, 54,3% naqueles idosos com 4 a 7 anos de estudo e 58,3% quando acima de 8 anos de estudo (p=0,020). A euforia n?o se mostrou presente em analfabetos e apresentou valores de 8,6% nos indiv?duos com 4 a 7 anos de escolaridade e 8,3% acima dos 8 anos de escolaridade (p=0,019). Ao analisar os sintomas comportamentais em rela??o ao decl?nio cognitivo, os del?rios apresentaram dados significativos com 5,0% no decl?nio cognitivo leve, 18,2% na dem?ncia leve e 35,7% na dem?ncia moderada (p=0,001). As alucina??es representaram 7,5% dos casos de decl?nio cognitivo leve, 21,8% nos casos de dem?ncia leve e 28,6% na dem?ncia moderada (p=0,024). A apatia foi de 15% no decl?nio cognitivo leve, 32,7% na dem?ncia leve e 35,7% na dem?ncia moderada (p=0,046). A desinibi??o apresentou 5,0% no decl?nio cognitivo leve, 12,7% na dem?ncia leve e 21,4% na dem?ncia moderada (p=0,042). Os sintomas neuropsiqui?tricos foram frequentes em indiv?duos com dem?ncia e aumentaram a preval?ncia com o tempo de evolu??o da doen?a. O aumento dos anos de vida contribuiu para o surgimento de SCPD em idades mais avan?adas, como os octagen?rios, idade na qual a doen?a pode estar na fase moderada. A avalia??o dos SCPD apresenta n?vel de evid?ncia A, devendo ser realizada em todos os pacientes.

Stream flowline delineation from high-resolution digital elevation models (HRDEMs) can be problematic due to the fine representation of terrain features as well as anthropogenic drainage structures (e.g., bridges, culverts) within the grid surface. The anthropogenic drainage structures (ADS) may create digital dams while delineating stream flowlines from HRDEMs. The study assessed the effects of ADS locations, spatial resolution (ranged from 1m to 10m), depression processing methods, and flow direction algorithms (D8, D-Infinity, and MFD-md) on hydrologic connectivity through digital dams using HRDEMs in Nebraska. The assessment was conducted based on the offset distances between modeled stream flowlines and original ADS locations using kernel density estimation (KDE) and calculated frequency of ADS samples within offset distances. Three major depression processing techniques (i.e., depression filling, stream breaching, and stream burning) were considered for this study. Finally, an automated method, constrained burning was proposed for HRDEMs which utilizes ancillary datasets to create underneath stream crossings at possible ADS locations and perform DEM reconditioning. The results suggest that coarser resolution DEMs with depression filling and breaching can produce better hydrologic connectivity through ADS compared with finer resolution DEMs with different flow direction algorithms. It was also found that stream burning with known stream crossings at ADS locations outperformed depression filling and breaching techniques for HRDEMs in terms of hydrologic connectivity. The flow direction algorithms combining with depression filling and breaching techniques do not have significant effects on the hydrologic connectivity of modeled stream flowlines. However, for stream burning methods, D8 was found as the best performing flow direction algorithm in HRDEMs with statistical significance. The stream flowlines delineated using the proposed constrained burning method from the HRDEM was found better than depression filling and breaching techniques. This method has an overall accuracy of 78.82% in detecting possible ADS locations within the study area.

IsaMill is a stirred type mill used in mineral industry for fine and ultra-fine grinding. The difficulty in obtaining the internal flow information in the mill by experimental techniques has prevented the development of the fundamental understanding of the flow and generating general methods for reliable scale-up and optimized design and control parameters. This difficulty can be effectively overcome by numerical simulation based on discrete element method (DEM). In this work a DEM model was developed to study particle flow in a simplified IsaMill. The DEM model was validated by comparing the simulated results of the flow pattern, mixing pattern and power draw with those measured from a same scale lab mill. Spatial distributions of microdynamic variables related to flow and force structure such as local porosity, particle interaction forces, collision velocity and collision frequency have been analyzed. Among the materials properties of particles, it is shown that by decreasing particle/particle sliding friction coefficient, the particle flow becomes more vigorous which is useful to grinding performance. Restitution coefficient does not affect the particle flow significantly. A too low or too high particle density could decrease grinding efficiency. Although grinding medium size affects the flow, its selection may depend on the particle size of the products. Among the operational variables considered, the results show that fill volume and mill speed proved to be important factors in IsaMil process. Increase of fill volume or mill speed increases the interaction between particles and agitating discs which results in a more vigorous motion of the particles. Among the mill properties, particle/stirrer sliding friction plays a major role in energy transfer from stirrer to particles. Although there exists a minimum collision energy as particle/stirrer sliding friction increases, large particle/stirrer sliding friction may improve grinding performance as it has both large collision frequency and collision energy. However, that improvement is only up to a critical particle/disc sliding friction beyond which only input energy increases with little improvement on collision frequency and collision energy. Reducing the distance between stirrers or increasing the size of disc holes improves high energy transfer from discs to particles, leading to high collision frequency and collision energy. Among the different stirrer types, the energy transfer is more effective when disc holes are present. Pin stirrer shows increased collision energy and collision frequency which also result in a high power draw. Using the DEM results, a wear model has been developed to predict the wear pattern of the discs. This model can be used to predict the evolution of the disc wear with the time. It is shown that energy transfer from discs to particles are increased when discs are worn out. An attempt has also been made to analyze the microdynamic properties of the mill for different sizes. It is shown that specific power consumption and impact energy are correlated regardless of the mill size and mill speed.
