Detoxification of dilute-acid lignocellulose hydrolysates by treatment with Ca(OH)2 (overliming) efficiently improves the production of fuel ethanol, but is associated with drawbacks like sugar degradation and CaSO4 precipitation. In factorial designed experiments, in which pH and temperature were varied, dilute-acid spruce hydrolysates were treated with Ca(OH)2, NH4OH or NaOH. The concentratio...

Background: A significant bone defect is a condition wherein the cannot repair spontaneously. Therefore, replacing defects with substitution remains reconstructive concern for orthopaedic surgeons. Bone Graft Substitution (BGS) are classified broadly, such as grafts (autograft, allograft, and xenograft) synthetic ceramics (hydroxyapatite, calcium sulphate). This study aims to determine e...

Abstract The objective of current research is to investigate distribution patterns of vegetation types and its relation with environmental factors in southern margin of Haj Aligholi Kavir of Damghan. Three vegetation types including Halecnemum strobilaceum, Sedlitzia rosmarinus and Artemisia sieberi were studied in marginal arid regions and uplands of the study area. Firstly, geographic locat...

In the present study, a total of sixty groundwater samples, twenty each for pre-monsoon, monsoon and post seasons 2018, were collected from selected locations in Mewat district Haryana, India. Electrical conductivity (EC) was measured at site dissolved solids (TDS) estimated. Samples analysed anions (chloride, sulphate, bicarbonate) cations (calcium, potassium, magnesium, sodium). Multiple regr...

The article deals with the effect of potassium sulfates on setting behavior cement pastes. It has been established that main elements (Ca, Si, Al) are distributed in composition clinker minerals, while K and S atoms concentrated locally pores formation arcanite. is shown interaction K2SO4 CaSO42H2O followed by syngenite K2Ca(SO4)2H2O causes destructive phenomena
