The present investigation in to find out the Emotional Intelligence of college level Students in Relation to their gender boys and girls. The sample consisted of 120 college level students out of which 60 where boys and 60 where girls. For this purpose of investigation “Emotional Intelligence Inventory” by S.K. Mangal and Shubhra Mangal was used. The obtained data were analyzed through‘t’ test ...
This study examined whether keeping or not keeping the products of a craft activity influences affective meaning and mood. Four groups of undergraduate (n = 23) and graduate (n = 20) students created block-printed stationery. Two groups were allowed to keep their stationery, and two groups were not. The measure of mood changes was the Bipolar Profile of Mood States, which subjects completed bef...
OBJECTIVE To investigate levels and predictors of change in dimensions of burnout after an intervention for stressed doctors. DESIGN Cohort study followed by self reported assessment at one year. SETTING Norwegian resource centre. PARTICIPANTS 227 doctors participating in counselling intervention, 2003-5. INTERVENTIONS Counselling (lasting one day (individual) or one week (group based))...
The literature concerning the relationship between emotional exhaustion and performance led researchers to raise questions about the extent to which the variables are related. In 2 time-lagged samples, the authors found that motivation mediates the emotional exhaustion-job performance relationship. Moreover, the authors found that participants appear to target their investment of resources in r...
Impaired cerebral autoregulation during marked reductions in arterial blood pressure may contribute to heat stress-induced orthostatic intolerance. This study tested the hypothesis that passive heat stress attenuates dynamic cerebral autoregulation during pronounced swings in arterial blood pressure. Mean arterial blood pressure (MAP) and middle cerebral artery blood velocity were continuously ...
This project presents a new addon self tuning control scheme to supplement its conventional PI control system in damping low frequency inter area power oscillations. Low frequency (0.1 to 0.8 Hz) inter-area oscillations are often observed when power systems interconnected through weak tie lines are subjected to disturbances such as faults, line outages and sudden load changes. Power System stab...
A solid state High Frequency (HF) 1 MHz, 40 kW source is intended for plasma formation in a neutral beam by inductive coupling of RF power. An important design feature such an HF its ability to sustain large transient swings load (due impedance transition on microsecond time scales). Power Supply (HFPS) has been configured with multiple Class-D H-bridge inverters modules using latest generation...
Optimizing a modulator driver for linear and high-speed operation, while simultaneously achieving high output voltage swing is very challenging. This paper investigates the design of highly-linear, high-bandwidth yet power-efficient Mach-Zehnder based on breakdown doubler concept, which overcomes transistors’ physical limitations enables swings twice as conventional differential pair amp...
A 0.6-V 34-μW delta–sigma modulator implemented by using a standard 0.13-μm complementary metal–oxide– semiconductor technology is presented. This brief analyzes a subthreshold-leakage current problem in switched-capacitor circuits and proposes subthreshold-leakage suppression switches to solve the problem. To verify the operation of the subthreshold-leakage suppression switches, two different ...
