Self-governing small regions of power systems, known as “microgrids”, are enabling the integration of small-scale renewable energy sources (RESs) while improving the reliability and energy efficiency of the electricity network.Microgrids can be primarily classified into three types based on their voltage characteristics and system arc
Simultaneous inversion of sonic, density, and electrical resistivity borehole-derived well logs, has been addressed in literature in recent years.However, this problem is not broadly studied for dual-porosity sandstone formations.In addition, most authors presumed salinity and matrix properties as known parameters in their studies.We integrate the
In this paper we present the first direct observational evidence that the condensation level in pyrocumulus and pyrocumulonimbus clouds can be significantly higher than the ambient lifted condensation level.In addition, we show that the environmental thermodynamic profile, day-to-day variations in humidity, and ambient wind shear all exert signific
This study measures the cost of organic milk production, and in particular, the differences in cost Boxers of production between organic and conventional milk in California.Results show that the total cost of production on a per cow and a per hundredweight basis is about 10% higher for organic producers than for conventional producers in the survey
Leiomyomas are rare benign tumours of the oesophagus that remain silent in more than 50% of the cases.Giant leiomyomas measuring Accessories more than 5 cm are very rare.A 47-year-old female presented with chest pain, cough and dysphagia for two months.Imaging studies were indicative of a 12.1x11.9 cm mass lesion in the distal oesophagus, CT guided
