Preliminary studies on power generation by Bacilli E1 using dual chamber microbial fuel cell

Microbial fuel cell (MFC) is a developed technology to utilize microbial degradation ability and turned the degradation products to electricity. One of the limiting factor that contributes to the performance level of MFC is the microorganism used in the MFC. In the present research, Bacilli E1 has been tested for its ability to utilize glucose and converted it to electricity in dual chamber MFC. The MFC operated using E1 produced a maximum average of open circuit voltage (OCV) of 0.8 V. Meanwhile, by inserting a 1000 Ω resistance in the MFC circuit, produced a stable voltage of 0.1 V and calculated current and power were 0.2 ± 0.017 mA and 0.1 Wm-2 Comparison of glucose based voltage production between individual and mixed culture shows similar pattern of voltage profile and since individual CC did not show any significant increase of OCV, it was concluded that Bacilli E1 plays major role in the present MFC for power production

Sexual dimorphism in the relationship between brain complexity, volume and general intelligence (g): a cross-cohort study

Changes in brain morphology have been reported during development, ageing and in relation to different pathologies. Brain morphology described by the shape complexity of gyri and sulci can be captured and quantified using fractal dimension (FD). This measure of brain structural complexity, as well as brain volume, are associated with intelligence, but less is known about the sexual dimorphism of these relationships. In this paper, sex differences in the relationship between brain structural complexity and general intelligence (g) in two diverse geographic and cultural populations (UK and Indian) are investigated. 3D T1-weighted magnetic resonance imaging (MRI) data and a battery of cognitive tests were acquired from participants belonging to three different cohorts: Mysore Parthenon Cohort (MPC); Aberdeen Children of the 1950s (ACONF) and UK Biobank. We computed MRI derived structural brain complexity and g estimated from a battery of cognitive tests for each group. Brain complexity and volume were both positively corelated with intelligence, with the correlations being significant in women but not always in men. This relationship is seen across populations of differing ages and geographical locations and improves understanding of neurobiological sex-differences
