The recent discovery of the 31-km-wide Hiawatha impact crater has raised unanswered questions about its age, impactor and highly unusual organic carbon component. Previous research suggests a fractionated iron meteorite impactor, a probable maximum 3–2.4 Ma impact age and a possible Younger Dryas impact age. The first objective in this study has been to investigate a possible link between the Cape York meteorites and the Hiawatha impact crater by comparing the chromium isotopic signature in chromite from a Cape York meteorite with the chromium isotopic signature in potential chromite from the Hiawatha impactor. The second objective has been to investigate a possible Hiawatha signature in the Younger Dryas deposits from Baffin Bay. The third objective has been to study the organic carbon component in impactites derived from the Hiawatha impact crater. Heavy mineral grains were separated from glaciofluvial sediment which contains Hiawatha impactite grains. Not a single chromite grain was found and the possible link to the Cape York meteorites could not be tested. The petrographic examination of Younger Dryas marine deposits resulted in absence of impact-related Hiawatha grains. A petrological investigation revealed that organic carbon was likely found in five of six variably shocked impactites derived from the Hiawatha impact crater. The character of the organic carbon varies between the samples and also within individual samples. Vitrinite reflectance measurements of the organic carbon in two impactites yielded low reflectance values compared to charcoalification experiments of wood. Organic particles with different reflectance in the same sample suggest that the particles had different impact histories prior to settling and becoming a rock. Diagnostic conifer cellular texture was found in at least one of the samples. The character of the organic particles in the impactites supports the suggestion in a previous study that the sources of the Hiawatha organic carbon component are unmetamorphosed surficial deposits containing dead conifer tree trunks and fine-grained layered clay and organic matter.  In this study it is concluded that the apparent absence of chromite in the examined glaciofluvial sediment sample corroborates the significance of previous research which suggests that the Hiawatha impactor was an iron meteorite. The apparent absence of impact related grains in the Younger Dryas deposits suggests that although a Younger Dryas age for the Hiawatha impact crater is less likely now, the possibility remains open. The organic carbon with diagnostic conifer cellular texture in the Hiawatha impactites corroborates the conclusion in a previous study that the Hiawatha impact-related organic carbon component stems from local, thermally degraded conifer trees with a probable age of ca. 3–2.4 Ma. It is also concluded that the relatively low reflectance values of the organic carbon in the Hiawatha impactites seem to be related to the short duration of the high-temperature excursion during the hypervelocity impact event.

In order to provide a sound economic basis for investment decisions to address this challenge, it is critical to assess the cost of these crashes. These estimates serve cost-benefit analysis inputs to facilitate a more efficient resources allocation for interventions to address the challenge posed by road crashes. South Africa has not been updating crash cost estimates on a regular basis, and those that were conducted used the much criticised human capital approach. Therefore, the available estimates could not be relied upon for planning purposes and comparison with the estimates of other countries. It is against this background that this study developed and illustrated the application of a hybrid framework for assessing the cost of road traffic crashes in South Africa. The framework uses the human capital approach and the willingness-to-pay approach in one study. Human capital approach cost estimates are needed to inform planning to maximize the national output, while the willingness-to-pay estimates are more suitable when the main concern is to inform interventions to increase social welfare by reducing injuries and fatalities. The willingness-to-pay approach uses the contingent valuation and the stated preference methods. A survey questionnaire with contingent valuation and stated preference questions was administered in two phases to a sample of 273 respondents within the transport industry. For the human capital approach, the cost estimates in the 2016 Cost of Crashes in South Africa report were adjusted for inflation using the 2017 rate of 5.3% to obtain 2017 cost estimates. This study revealed that the human capital approach underestimates the cost of road crashes. The study contributes to the body of knowledge by using the human capital approach and the willingness-to-pay approach in one study to illustrate the applicability of this hybrid/ combination within the South African context. Future research needs to replicate this study on a sample drawn from all nine provinces of South Africa, so that the cost estimates are representative of the country’s population. / Ukuphazamiseka komgwaqo kungenye yezingozi ezimbi kakhulu zokuhamba komgwaqo emhlabeni jikelele, ezimele inkinga enkulu yenhlalo nezomnotho ikakhulukazi emazweni asathuthuka njengeNingizimu Afrika.

A investigação estimou a prevalência de enteroparasitas em 200 crianças de 2 a 13 anos pertencentes a duas classes sócio-econômicas distintas, média e baixa, no período de abril a junho de 2001, na cidade de Porto Velho, RO. E também analisou os fatores contextuais de risco de maior importância epidemiológica. As amostras de fezes foram examinadas pelos métodos Direto e Sedimentação Espontânea. A população de nível sócio-econômico médio (A) composta por 100 indivíduos, apresentou um índice de positividade de 18%, sendo o parasita mais prevalente, Giardia lamblia (52,4%), seguido por Ascaris lumbricoides (19,0%), Trichuris trichiura (14,3%), Enterobius vermicularis (4,8%), Hymenolepis nana (4,8%) e Endolimax nana (4,8%). No grupo de nível sócio-econômico baixo (B), a positividade atingiu 56% dos indivíduos, sendo também Giardia lamblia (28,9%) o mais prevalente, seguido por Entamoeba calí (22,7%), A. lumbricoides (14,4%), T. Trichiura (8,3%), E. vermicularis (7,2%), H. nana (4,1%), E. nana (4,1%), E. histolytica (4,1%), Ancylostomidae (3,1%) e leveduras (3,1%). A ocorrência de mais de um parasito por indivíduo foi maior no grupo B (46,4%), sendo que o parasitismo foi mais prevalente entre as crianças com sintomas gastrintestinais em ambos os grupos A e B. As parasitoses intestinais afetaram igualmente meninos e meninas; negroides e caucasóides e ocorreram igualmente nas duas faixas etárias de crianças menores e maiores de cinco anos, contudo as crianças com menos de cinco anos de grupo A apresentaram predomínio de infecção por protozoários da espécie G. lamblia. A baixa renda salarial e residências com numero elevado de pessoas coabitando e sem rede de abastecimento de água se constituíram em fatores de risco socioeconômicos que favorecem a elevada prevalência das parasitoses intestinais. As condições de anemia e estado nutricional também foram avaliadas e não mostraram associação significantes com enteroparasitoses, nos diferentes grupos sócio-econômicos. Logo, a elevada prevalência de crianças, em especial de baixo nível sócio-econômico, com parasitismo intestinal, anemia e com desnutrição aguda moderada, refletem as precárias condições de saúde pública na cidade de Porto Velho-RO. / Parasitic infections are present in endemic ways in several areas of Brazil. The investigation estimated the prevalence of enteroparasites in 200 children between 2 and 13 years belonging to two distinct social-economic classes, middle and low, in a period from April to June in 2001 in the city of Porto Velho, RO. And it also analyzed the contextual risk factors of greater epidemiologic importance. The samples of the feces were examined through direct and spontaneous sedimentation method. The population of middle social-economic level (A) made up of 100 individuals, presented a positivity rate of 18 %, being the most prevalent parasite Giardia lamblia (52,4 %), followed by Ascaris lumbricoids (19 %), Trichuris trichiura (14,3%), Enterobius vermicularis (4,8%), Hymenolepis nana (4,8%) and Endolimax nana (4,8%). In the group of low social-economic level (B) the positivity reached 56 % of the individuals also being Giardia lamblia (28,9%) the most prevalent, followed by Entamoeba coli (22,7%), A. lumbricoides (14,4%), T. Trichiura (8,3%), E. vermicularis (7,2%), H. nana (4,1%), E. nana (4,1%), E. histolytica (4,1%), Ancylostomídeos (3,1%) and leaven (3,1%). The occurrence of more than one parasite per individual was more prevalent in among the children of group B (46,4%), being that the parasitism was more prevalent among children with gastrointestinal symptoms in both groups A and B. The intestinal parasitosis affected boys and girls equally; Negroid and Caucasian and occurred equally in both two age group of children under and above five years, however, children under the age of five of group A presented preponderance of infection by protozoan of the specie G. lamblia. Low income and houses with a great number of people cohabiting and without water supply net constituted social-economic risk factors that support the high prevalence intestinal parasitosis. Anemia and nutritional state conditions were also evaluated and did not show significant relations with enteroparasitosis, in the different social-economic groups. Therefore, high prevalence in children, especially of low social-economic level, with intestinal parasitism, anemia and moderate acute malnutrition, reflect the precarious public healthy conditions in the city of Porto Velho, RO.

Para evitar esses inconvenientes, a engenharia de manutencao lanca mao de ferramentas estrategicas para a gestao e solucoes dos problemas, visando a otimizacao, juntamente com circulo virtuoso de melhorias continuas nos processos de manutencao. Este trabalho tem por finalidade fazer uma analise da Metodologia de Analise e Solucao de Problemas (MASP), como ferramenta de gestao estrategica na busca e solucao de problemas no ambito da engenharia de manutencao. Para isso, inicialmente, apresenta-se uma serie de informacoes sobre a gestao da manutencao, bem como todo o arcabouco que envolve qualidade e ferramentas gerenciais. Com o capitulo que trata especificamente do MASP, tem-se uma nocao mais exata do quanto cada ferramenta e necessaria para que se possa desenvolver um bom trabalho, visto que ele retrata que essa metodologia nada mais e do que o somatorio de todas as ferramentas existentes, colocadas de maneira ordenada. Por fim, apresentam-se quatro estudos de casos, pelos quais pretendemos demonstrar a Metodologia de Analise e Solucao de Problemas e a aplicabilidade na gestão estratégica, com visão em resultados no ambiente da engenharia de manutenção no pilar das manutenções programadas e autônomas - MP/MA, no ambito da Divisãoo de Transmissão de Ji-Parana/RO - ORDJ, vinculada a Centrais Eletricas do Norte do Brasil (Eletronorte). Na conclusao, faz-se uma analise critica do uso da metodologia na prestação de serviços, baseada na aplicaão supracitada. / Typically, maintenance programs implemented in companies for generation, transmission and distribution of electricity that seek to avoid failure will cause the removal of equipment from the electrical system, which means large financial losses, either by decreased revenues, either by paying fines the regulatory agency, in addition to decreased system reliability. To avoid these drawbacks, the maintenance engineering makes use of strategic tools for the management of problems and solutions aimed at optimizing along with virtuous cycle of continuous improvement in maintenance processes. This study aims to make an analysis of the Methodology Analysis and Troubleshooting (MASP) as a strategic management tool to find and solve problems within the maintenance engineering. Thus initially presents a lot of information on the management of maintenance as well as the entire framework involving quality and management tools. With the chapter that deals specifically with MASP, have become a better sense of how each tool is required so that we can develop a good job, since it portrays that this methodology is nothing more than the sum of all existing tools placed in an orderly manner. Finally, we present four case studies where we intend to demonstrate the methodology Analysis and Troubleshooting (MASP) and applicability in strategic management vision into results in environmental engineering maintenance on the pillar of scheduled maintenance and autonomous - MP/MA within the Transmission Division Ji-Parana/RO - ADJR, linked to Power Plants in Northern Brazil (Eletronorte). In conclusion, it is a critical analysis of the methodology used in the provision of services, based on the above application.
