Conservation agriculture based sustainable intensification: Increasing yields and water productivity for smallholders of the Eastern Gangetic Plains

Verified

Saiful Islam, Mahesh K. Gathala, Thakur P. Tiwari, Jagadish Timsina et al.

Journal: Field Crops ResearchYear: 2019Citations: 95

In the Eastern Gangetic Plains (EGP) region of South Asia cropping systems are predominantly rice-based and comprise rice and non-rice crops (e.g. maize, wheat, lentil, mungbean, jute) in rotation. There are large gaps between potential crop yields and those achieved in farmers’ fields, primarily du...

Hydrodynamic Behaviors of the Two-Phase Turbulent Flow of Microalgae Suspension and CO2 in a Photobioreactor for Biofuel Production

Verified

Mohammad Iftekhar Monir, Nurun Nahar, Ujjwal Kumar Deb, Anjan Kumar Chowdhury

Journal: WSEAS TRANSACTIONS ON HEAT AND MASS TRANSFERYear: 2026

Microalgae cultivation in horizontal loop tubular photobioreactors (HLTPs) is more efficient for biofuel production than other methods. It is important to inject CO2 into the photobioreactors to ensure microalgal growth. Due to the complex flow path and bubble arising from CO2 penetration in the tub...

A Rare Case of Partially Ossified Sacrospinous Ligament Causing Sciatic Nerve Compression.

Verified

Rouzbeh Shams, Maroof Ahmad Khan, A A Islam, Munny Das et al.

Journal: PubMedYear: 2024

Ossification of sacrospinous ligament induces a great risk for maintaining the stability of the pelvis. The sacrospinous ligament, along with the sacrotuberous ligament, plays a distinct role in the sacroiliac joint and pubic symphysis stability. The ossification may cause compression of neurovascul...
