To assess the scope for enhancing productivity of soybean (Glycine max L. Merr.), the CROPGRO-Soybean model was calibrated and validated for the diverse soybean-growing environments of central and peninsular India. The validated model was used to estimate potential yields (water non-limiting and water limiting) and yield gaps of soybean for 21 locations representing major soybean regions of Ind...

A small, light, wireless borehole probe has been developed and built which consists of pressure and temperature sensors and a mini-datalogger/programmed microprocessor in a closed metal tube, water-tight up to 100 bar. The probe (235mm long, 23mm dia, 99.8 g) sinks in completed but not yet working borehole heat exchangers (BHEs) through its own weight to the bottom of the BHE U-tube and records...

Horizontal drilling is an important development in the petroleum industry and it relies heavily on guiding the drill bit with the aid of sonic logging, i.e. geosteering. The quality of sonic imaging depends heavily on the effective suppression of borehole waves and enhancement of weak reflection signal. To this end, we propose an approach to image the near-borehole structure using acoustic logg...

The province of Central Kalimantan contains about three million hectares of peatland, which is one of the largest unbroken tropical peatland areas in the world. Peat swamp forest (PSF) is among the earth's most endangered and least known ecosystem (12). They have a huge carbon storage capacity and are extremely fragile and liable to disturbance (10). Local communities have used them extensively...

Understanding the causes underlying changes in species diversity is a fundamental pursuit of ecology. Animal species richness and composition often change with decreased forest structural complexity associated with logging. Yet differences in latitude and forest type may strongly influence how species diversity responds to logging. We performed a meta-analysis of logging effects on local specie...

the effect of tricyclazole application on waterlogging damage alleviation in canola seedlings was evaluated in a pot experiment in complete randomized design layout with three replications. treatments included: control (no waterlogging), waterlogging, tricyclazole plus waterlogging and tricyclazole. tricyclazole (75%) applied at three-leaf stage on canola seedlings. seedlings were exposed to wa...
