INTRODUÇÃO

Visão geral sobre todo conteúdo abordado no relatório.

Objetivos

Objetivos do trabalho e do uso de análises térmicas.

Desenvolvimento

Procedimento Experimental

Descrição da etapa de preparação das amostras (pós usados, qual a liga utilizada, método de fabrico das amostras...); Breve descrição dos equipamentos usados (tanto de STA quanto de Dilatometria); Descrição detalhada do experimento em si (atmosfera usada, ciclo térmico, fluxo de gás, limpeza do forno, medidas de densidade, linhas base em STA...)

Resultados

Densidades obtidas, densificação e porosidade da amostra, contração na sinterização e cálculo do coeficiente de expansão linear; Gráficos de Sinterização, Dilatometria e STA.

Análise dos Resultados

Análise dos gráficos e explicações acerca destes e do procedimento experimental utilizado. Pontos importantes (não estão em ordem):

✓ Explicar o motivo da escolha de determinado gás para cada ensaio; ✓ Na Sinterização e Dilatometria: Explicar todas as expansões e contrações presentes no gráfico; ✓ No STA: Explicar a ocorrência dos picos, caracterizando-os como de primeira ou segunda ordem e identificando as mudanças/reações; ✓ Apresentar as taxas aquecimento e resfriamento, bem como sua influência nos resultados obtidos; ✓ Explicar a diferença existente entre o intervalo de fusão e o intervalo de solidificação; ✓ Indicar de que modo a preparação das amostras influencia nos resultados; ✓ Comparar a diferença entre os gráficos de Sinterização, Dilatometria e STA para cada elemento de liga usado (apresentar todas as linhas em um único gráfico, gráfico comparativo) e elucidar a influência do elemento de liga “do grupo” na sinterização, transformação de fase na dilatometria e picos no STA.

    The purpose of this experiment was used to identify the chemical changes a substance undergoes by knowing some of its chemical properties like (Change in color, producing bubbles and gas, precipitation, conductivity). The aim of today’s lab was to help us identify different households and their components, they contained whether they were acid/ base, because most of the households are based on those solutions like (i.e. Acetic acid = Vinegar = CH3COOH can be used in cooking) or bases solutions like (bleach is applied for cleaning and also to remove dirt’s). And to identify those substances we can do testify them by observing the change in litmus paper (i.e. acids when the dissolve in the solution they produces Hydronium ions H3O+…

    The piece by Castillo is a personal reflection that offers a peculiar and particular point of view from one person, and that represents how people permeates their surrounding reality, in this case the Mexican Revolution. These kinds of sources are extremely valuable in order to listen to the average voices. Especially in the case of underprivileged groups, such as indigenous populations and women, sometimes this is the only opportunity to grasp intimate daily moments, practices, and customs.…

    The American Civil war as no different yes, it was a war where a nation fought against itself and it is now seen as one of the bloodiest war in U.S. history, but the north (The Union) had modern, more advanced technology in the navy and the army. Whereas the south (The Confederate) was not as advanced and their navy and army lacked the modern weapons that the north had. Modern technology isn't the only reason why the north won the civil war. The north used the modern technology that they had and planned their strategies and tactics around the technology. During the civil war, the introduction of ironclads was only the tip of the iceberg because there also came the development of building submarines, underwater mines, and torpedoes.…

    People believe that God is standing there ready to punish us for our wrongdoings but in actuality God is not standing over us ready to punish us when we do wrong a lot of people think and believe and even say if you do this God will punish you like they say in Spanish, Diosito te va castigar, also saying this because of our suffering does it mean that God is punishing us many times we do our own suffering because of our own Disobedience to God. There are blessing for obedience and there's curse for Disobedience a lot of suffering that we go through is because of our own doing not of God's doing so we have to acknowledge that our sufferings come through times in our lives that we have done something or have said something 2 suffer and that is…

    Aceasta a luat fiinta in jurul Lacului Ursu (46.000 mp) care s-a format in anul 1875 fiind unul dintre cele mai mari lacuri sarate, heliotherme din Europa. In timpul verii temperatura apei din lac este de pana la 40-50 grade C la adancimea de 1,5-2 m. Alaturi de Lacul Ursu mai puteti gasi in Sovata si alte lacuri: Alunis, Verde, Negru, Rosu, Mierlei si Serpilor, dar de o dimensiune mai mica. Chiar daca statiunea este asezata pe un munte de sare, exista aici, paduri bogate de fagi, stejari, castani, brazi si mesteceni. Statiunea are o clima subalpina, cu veri…
