Method for determining reaction rate of mild steel containers during melting of magnesium-aluminium alloys and effect of aluminium content on directionally solidified microstructures

A magnesium alloy of eutectic composition (33 wt-'%Al) was directionally solidified in mild steel tubes at two growth rates, 32 and 580 mum s(-1,) in a temperature gradient between 10 and 20 K mm(-1). After directional solidification, the composition of each specimen varied dramatically, from 32'%Al in the region that had remained solid to 18%Al (32 mum s(-1) specimen) and 13%Al (580 mum s(-1) specimen) at the plane that had been quenched from the eutectic temperature. As the aluminium content decreased, the microstructure contained an increasing volume fraction of primary magnesium dendrites and the eutectic morphology gradually changed from lamellar to partially divorced. The reduction in aluminium content was caused by the growth of an Al-Fe phase ahead of the Mg-Al growth front. Most of the growth of the Al-Fe phase occurred during the remelting period before directional solidification. The thickness of the Al-Fe phase increased with increased temperature and time of contact with the molten Mg-Al alloy. (C) 2003 Maney Publishing.

The Use of Thermal Capacity in Measuring the Effectiveness of Meals on Wheels Transport Containers

The Meals on Wheels (MOW) program is designed to help combat hunger in persons needing assistance. MOW has a duty not only to provide food but also to ensure that it reaches eligible clients safely. Given the population that MOW serves, transporting food safely takes on increased importance. This experiment focused on the major food safety issue of maintaining temperature integrity through the use of transport containers. For containers that did not contain electric heating elements, several factors influenced how fast the food temperature fell. Those factors included the U-value and size of the container as well as how many meals were in the container. As predicted, the smaller the U-value, the longer it took the temperature to fall. Larger containers did better at maintaining food temperatures, provided they were fully loaded. In general, fully loaded small and medium containers were better at maintaining food temperatures than larger containers loaded with the same number of meals.

Optimal location of solid waste containers in Alcalá de Henares

The waste’s rise is a problem that affects the environment as a whole and we cannot forget about it. A good waste’s management is the key to improve the future prospect, and the waste collection is key within the management activities. To find out the better way to collect wastes leads to a reduction of the social, economic and environmental cost. With the use of the Geographic Information Systems it has been intended to elaborate a methodology which allowed us to identify the most suitable places for the location of the collection containers of the different sorts of the solid urban wastes. Taking into account that different types of wastes exist, not all of them should be managed in the same way. Therefore we have to differentiate between models where we apply efficiency and models where we apply equity for the collection of wastes, bearing in mind the necessities of each waste.

Avaliação da anchoita (engraulis anchoita) salgada maturada acondicionada em atmosfera modificada

A anchoita foi capturada e acondicionada a bordo sob-resfriamento a 0°C com gelo em escamas. Após o recebimento, o pescado foi processado na forma salgado-maturado. Após a maturação foram processadas e embaladas em sacos de polietileno e armazenadas sob-refrigeração a 5°C durante 84 dias. As amostras foram divididas grupos: (1) sob pressão atmosfera normal, (2) vácuo, (3) atmosfera modificada com 50% CO2 + 20% O2 + 30% N2 e (4) 60% CO2 + 10% O2 + 30% N2, em embalagens de polietileno e aluminizadas, termo-seladas e armazenadas sob-refrigeração a 5°C. Os valores de textura tiveram uma redução de 2277,8 N (Kg.m/s2 ) para 821,90 N (Kg.m/s2 ) para o tratamento controle. A qualidade inicial do pescado atendeu aos padrões legais vigentes, apresentando ausência Salmonella sp e enumerações aceitáveis aos padrões de Staphylococcus coagulase positiva, Clostridium sulfito redutores, coliforme totais e a 45ºC. Com relação ao pH, houve diferenças significativas durante o tempo de processamento (p<0,05), o valor passou de 6,3 (início) para 6,4 (final). Com relação aos resultados correspondentes aos parâmetros L*, a* e b* (cor), em todos os tratamentos e ao longo do tempo de processamento (ambas as embalagens), ocorreram diferenças significativas (p<0,05). Os valores de L* variaram de 34,80 para 18,00 (controle) 23,00 (vácuo), 20,21 (T3) e 22,00 (T4) embalagens de polietileno. Nas embalagens de alumínio os valores de L* variaram de 34,00 para 25,00 (controle), 29,00(vácuo), 22,10 (T3) e 26,00 (T4).

PRODUÇÃO DE MUDAS DE UMBUZEIRO ( Spondias tuberosa Arruda Câmara) EM DIFERENTES SUBSTRATOS E TAMANHO DE RECIPIENTES

A espécie Spondias tuberosa Arr. Cam. (umbuzeiro) destaca-se como uma das espécies arbóreas de maior potencial do semiárido brasileiro. Apesar de sua relevante importância socioeconômica e ambiental, há falta de estudos voltados para o estabelecimento de um modelo de produção de mudas da espécie. O objetivo desse trabalho foi avaliar a produção de mudas de Spondias tuberosa utilizando diferentes substratos e tamanho de recipientes. O experimento foi conduzido no viveiro do Laboratório de Ecologia Vegetal (LEV) do Centro de Ciências Agrárias (CCA) da Universidade Federal da Paraíba (UFPB), Areia - PB. O delineamento experimental usado foi em blocos casualizados em esquema fatorial 2 x 7 e parcelas subdivididas, sendo que os recipientes representaram as parcelas e os substratos as subparcelas. Foram utilizados substratos formulados a partir da mistura de terra de subsolo (37,5-100%), areia lavada (12,5- 25%) e esterco bovino curtido (10-50%). Os recipientes utilizados foram sacos de polietileno preto com volumes de 1900 cm3 (15 x 27 cm) e 5000 cm3 (25 x 26 cm). Para a obtenção das plântulas, sementes de Spondias tuberosa foram semeadas em sementeira de alvenaria até a repicagem (90 dias após o semeio). Aos 78 dias, após a repicagem, as mudas foram avaliadas quanto à altura, diâmetro do colo, relação altura/ diâmetro do colo, diâmetro do xilopódio, comprimento de raiz, massa seca da parte aérea e raiz. Os dados obtidos foram submetidos à análise de variância e ao teste F, sendo as médias comparadas pelo teste de Tukey ao nível de 5% de probabilidade, utilizando o software SISVAR®. Os substratos com esterco bovino curtido proporcionaram os maiores valores em altura e comprimento de raiz. Para a produção de mudas de Spondias tuberosa, é recomendado o substrato contendo terra de subsolo (45%) + Areia (15%) + Esterco bovino (40%).
