SEMESTER: JULY-DECEMBER’09The experiment was conducted to study the effect of a seed treating chemical
and three plant extracts on management of Aphid and Sawfly infesting mustard
in relation to sowing time in the field of Sher-e-Bangla Agricultural University
farm, Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from
November 2008 to March 2009. In these study the environmental factors were
evaluated at three time e.g.23 November, 30 November and 06 December,
2008. The experiment comprised of the following treatments; T1: Confider
70WG @ 3 g/kg seeds; T2: Zinger extract @ 20 ml/L water at 7 days interval;
T3: Turmeric extract @ 20 ml/L water at 7 days interval; T4: Neem leaf extract
20 ml/L water at 7 days interval and T5: Control. Three experiments were laid
out in three sowing times. Each experiment was set in a Randomized Complete
Block Design (RCBD) with three replications. For sowing on 23 November
2008, the lowest number of aphid and sawfly was recorded from T4, while the
highest number obtain from T5 treated plots at early, mid and late flowering
and fruiting stages. The seed yield per hectare was recorded highest from T4
(2.34 t/ha), while the lowest from T5 (2.01 t/ha) treated plots. Sowing on 30
November, 2008 showed the lowest number of aphid and sawfly in T4, while
the highest number from T5 treated plots at early, mid and late flowering and
fruiting stages. The highest yield was obtained from T4 (2.64 t/ha), while the
lowest yield was recorded from T5 (2.02 t/ha) applied plots. Mustard sown on
06 December, 2008 the lowest number of aphid and sawfly in T4, while the
highest number in T5 treated plots at early, mid and late flowering and fruiting
stages. The highest yield was recorded from T4 (2.21 t/ha) and the lowest yield
from T5 (1.95 t/ha) applied plots
Temporal Dynamics of Brain Activity in Response to Stimuli in the Parietal Region: An fMRI Analysis
No full textThis study explores the temporal dynamics of brain activity in response to stimuli, focusing on differences between control and schizophrenia groups. Using functional Magnetic Resonance Imaging (fMRI) data, the study examines blood-oxygen-level-dependent (BOLD) signal intensities across multiple brain regions—specifically the parietal and frontal cortices—crucial for cognitive processing. Analyses reveal that while control group participants exhibit rapid and consistent peak responses in these regions, the schizophrenia group shows delayed, lower-intensity peaks, indicating slower and less efficient neural processing. The schizophrenia group also demonstrates increased variability in signal patterns, suggesting potential dysconnectivity and instability in neural responses, particularly within networks involved in attention and executive functions. These findings highlight the distinct neural response profiles associated with schizophrenia and suggest potential biomarkers for cognitive dysfunctions related to the disorder, with implications for personalized therapeutic approaches targeting these neural deficits.
