Two studies, comprising 128 participants, were conducted to examine possible detrimental effects of noise and moderate heat stress on decision making. Three tasks involving risky decisions were used: a lottery choice task, the Balloon Analogue Risk Task, and two risk scenario questionnaires. Study 1 ( n = 97) involved three noise stressors presented at 60dB(A) and a quiet condition. Compared with all other conditions, a radio podcast about the jubilee of museums caused a significant increase in risk aversion in the Choice Dilemma Questionnaire task. Study 2 ( n = 31) compared two groups that completed the aforementioned tasks either in a warm (≥ 30°C) or neutral (≤ 25°C) ambient temperature condition. Participants made significantly riskier decisions in the warm ambient temperature condition in all tasks except the lottery task. Effects were more pronounced among female subjects. Especially elevated ambient temperatures should, therefore, be monitored in office environments to prevent impairments of decision making.

Temperature Storage

Crude palm oil (CPO) is currently the most preferable feedstock to be converting into biodiesel via transesterification process in this region. Though the commercial projections for biodiesel have grown, there remains some concerns with respect to its resistance to degradation during storage that possibly will compromise the fuel quality. The purpose of this study is to investigate the influences of ambient temperature condition on properties of biodiesel characteristics and emission. The biodiesel samples were stored and monitored in glass container at the temperature 6°C, 25°C and 30°C, and blending of biodiesel was varied from 5vol% (B5) - 45vol% (B45). The changes of density, kinematic viscosity, flash point, water content, acid value, and as well as emission of CO2 and CO were observed. The result show storage under ambient temperatures properties of CPO biodiesel were found to have higher value compare to the other temperature storage and also have significant effect on the CO emission.

Risky Decisions

Adolescent decision-making is a topic of great public and scientific interest. However, much of the neuroimaging research in this area contrasts only one facet of decision-making (e.g., neural responses to anticipation or receipt of monetary rewards). Few studies have directly examined the processes that occur immediately before making a decision between two options that have varied and unpredictable potential rewards and penalties. Understanding adolescent decision-making from this vantage point may prove critical to ameliorating risky behavior and improving developmental outcomes. In this study, participants aged 14–16 years engaged in a driving simulation game while undergoing fMRI. Results indicated activity in ventral striatum preceded risky decisions and activity in right inferior frontal gyrus (rIFG) preceded safe decisions. Furthermore, participants who reported higher sensation-seeking and sensitivity to reward and punishment demonstrated lower rIFG activity during safe decisions. Finally, over successive games, rIFG activity preceding risky decisions decreased, whereas thalamus and caudate activity increased during positive feedback (taking a risk without crashing). These results indicate that regions traditionally associated with reward processing and inhibition not only drive risky decision-making in the moment but also contribute to learning about risk tradeoffs during adolescence.
