Machine learning technology in biohydrogen production from agriculture waste: Recent advances and future perspectives.

Agricultural waste biomass has shown great potential to deliver green energy produced by biochemical and thermochemical conversion processes to mitigate future energy crises. Biohydrogen has become more interested in carbon-free and high-energy dense fuels among different biofuels. However, it is challenging to develop models based on experience or theory for precise predictions due to the complexity of biohydrogen production systems and the limitations of human perception.

Feasibility of Laparoscopic Hysterectomy in Stage IV Pelvic Endometriosis: Our Technique and Outcomes.

Context: The definitive surgical treatment of severe endometriosis remains to be hysterectomy whether done by laparoscopy or laparotomy.

Aim: The aim of this study was to assess the feasibility and outcome of laparoscopic hysterectomy in severe pelvic endometriosis.

Settings And Design: This retrospective study was carried out in a tertiary center over a period of 5 years (January 2013-December 2017).

Graphene oxide coated with porous iron oxide ribbons for 2, 4-Dichlorophenoxyacetic acid (2,4-D) removal.

Graphene oxide (GO) was prepared from commercially available graphite powder. Porous iron oxide ribbons were grown on the surface of GO by solvothermal process. The prepared GO-FeO nanocomposites are characterized by FT-IR, XRD, VSM, SEM, TEM, Raman spectroscopy, surface functionality and zero point charge studies.

Geochemical assessment of heavy metals pollution in surface sediments of Vellar and Coleroon estuaries, southeast coast of India.

Surface sediments were collected from Vellar and Coleroon estuaries for determine sediment texture, calcium carbonate, organic matter and heavy metals. Pollution indices such as pollution load index (PLI), contamination factor (CF), enrichment factor (EF) and geo-accumulation index (I) were done for this study to know the level of heavy metals pollution in the estuarine ecosystem. Pearson correlation matrix and factor were used to assess the relationship and source of heavy metals in the estuarine sediments.

Assessment of trace element accumulation in surface sediments off Chennai coast after a major flood event.

The present study was conducted to assess the trace element concentration in marine surface sediments after major flood event of Chennai metropolis, India. Thirty surface samples were collected from off Chennai coast. Trace elements, organic matter, CaCO, sand-silt-clay and C/N ratios were studied to understand the accumulation dynamics on sediments.
