The building information modelling trajectory in facilities management: A review

There is a paucity of literature that examines building information modelling (BIM) for asset management within the architecture, engineering, construction and owner-operated (AECO) sector. This paper therefore presents a thorough review of published literature on the latest research and standards development that impact upon BIM and its application in facilities management (FM) during the operations and maintenance (O&M) phase of building usage. The purpose is to generate new ideas and provide polemic clarity geared to intellectually challenge readers from across a range of academic and industrial disciplines. The findings reveal that significant challenges facing the FM sector include the need for: greater consideration of long-term strategic aspirations; amelioration of data integration/interoperability issues; augmented knowledge management; enhanced performance measurement; and enriched training and competence development for facilities managers to better deal with the amorphous range of services covered by FM. Future work is also proposed in several key areas and includes: case studies to observe and report upon current practice and development; and supplementary research related to concepts of knowledge capture in relation to FM and the growing use of BIM for asset management

In-vitro cytotoxicity of aflatoxin B1 to broiler lymphocytes of broiler chickens

The aim of the present work was to study the in-vitro cytotoxic effects of different concentrations of aflatoxin B1 (AFB1) on broiler lymphocytes. Lymphocyte-rich mononuclear cells were separated by Ficoll-Histopaque density and cultured in 96-wellplates containing the evaluated AFB1 concentrations in 5% CO2 atmosphere at 39°C. Thereafter, MTT, PicoGreen, and reactive oxygen species assays were performed. Cell viability decreased in the presence of 10 µg/mL AFB1 at 48 h (p < 0.05) and of 10 and 20 µg/mL AFB1 at 72 h (p < 0.01 and p < 0.001, respectively) when compared to the control (0 µg/mL). However, a dose-dependent increase in the cell-free DNA at 24 h was observed at 1, 10 and 20 µg/mL (p < 0.001). ROS formation significantly increased at 24 h at all concentrations (p < 0.001). The in-vitro results demonstrate that AFB1 is cytotoxic and causes biomolecular oxidative damage in broiler lymphocytes

Obesidade em idosos do Município de São Carlos, SP e sua associação com diabetes melito e dor articular

Este estudo tem por objetivo verificar a prevalência de obesidade e sua associação com diabetes melito (DM) e dores articulares na população idosa residente em São Carlos, SP. Foram avaliadas 227 idosas (média de idade 69,6±6,8 anos) e 172 idosos (69,4±6,7 anos) quanto ao índice de massa corporal (IMC) e questionados quanto à presença de diabetes e dor articular. Os dados foram tratados estatisticamente. Os resultados mostram que 73,6% das idosas e 66,9% dos idosos apresentavam sobrepeso ou eram obesos. As médias de IMC foram maiores nos indivíduos com idade inferior a 75 anos. Entre as mulheres da amostra foi encontrada associação entre a presença de DM, dores no pé, tornozelo e joelho e a condição"obesa". No grupo masculino, a condição obeso só apresentou associação com a presença de DM. Foi pois constatada associação entre obesidade e presença de DM. Mulheres idosas apresentam maior prevalência de obesidade e associação entre dores articulares e excesso de peso corporal.The aim of this study was to assess prevalence of obesity and its association with diabetes mellitus (DM) and joint pain among elderly dwellers in the city of São Carlos, SP, Brazil. A total of 399 aged people - 227 women (mean age 69.6±6.8) and 172 men (mean age 69.4±6.7) - were assessed as to body mass index (BMI) and were questioned whether they had diabetes and joint pain. Data were statistically analysed. Results showed that 73.6% of the women and 66.9% of the men were overweight or obese; BMI values were higher in subjects aged under 75. Among women, associations were found between the obese condition, presence of diabetes, and foot, ankle and knee pain. In the male group, the obese condition presented association only with presence of diabetes. An association was hence found between obesity and DM. Prevalence of obesity was greater in elderly women, who also presented association between joint pain and high BMI values
