This study investigates a new concept of producing precipitated calcium carbonate (PCC) from steelmaking slag and carbon dioxide via a spray carbonation process. The presented laboratory-scale spray carbonation test reactor uses a spray nozzle to disperse fine droplets of a Ca-rich solution into a spray tower, where calcium carbonate precipitates as a result of the reaction between calcium and ...

429 Zingiber officinale Rosc. (Ginger), Curcuma longa Linn. (Turmeric) and Tinospora cordifolia (Willd.) Miers. ex Hook. f. & Thoms. (Guduchi) are the important spices and herbs. Ginger and turmeric are widely grown in different regions of India and are commercially important edible spices. Guduchi, as a drug plant, has bulk demand in the market ranging from 300 to 500 tonnes of dry woody stems...

The high diversity and abundance of vascular epiphytes in tropical montane cloud forest is associated with frequent cloud immersion, which is thought to protect plants from drought stress. Increasing temperature and rising cloud bases associated with climate change may increase epiphyte drought stress, leading to species and biomass loss. We tested the hypothesis that warmer and drier condition...

This study aimed to investigate the potential use of cold-pressed pomegranate seed oil by-product (PGOB) and grape (GOB) as a natural antioxidant in salad dressing. Firstly, bioactive compounds from were extracted powdered by spray drier produced powder (GOBP) (PGOBP). was first attempt evaluate oxidative stability dressing OXITEST at 90, 100, 110 °C, 6 bar (the oxygen pressure). The samples en...

In this study, the effect of edible coat (carboxy methyl cellulose) before osmotic dehydration anddifferent drying methods on sensory and physical properties of dried apple (V. Golden delicious)rings was investigated. The coated and non-coated samples pretreated with 50% sucrose osmoticsolution and dried in freeze drier (-40 to -50°C, 0.026-0.017 mbar, 24 hr), vacuum drier (70°C, 200mbar, 8-10 ...

This Review provides a general understanding of paper spray-MS, including the methodology and theory associated with a number of different related applications. This method has become a direct sampling/ionization method for mass spectrometric analysis at ambient conditions and, as a result, it has greatly simplified and increased the speed of mass-spectrum analysis. It has now become an increas...

The current study focuses on comprehensive fuel spray modeling and its effects on chamber acoustics in combustion dynamics simulations. The fuel spray is modeled using an Eulerian-Lagrangian approach describing the atomizer internal flow, primary atomization, and secondary atomization processes. To anchor the fuel spray model, a series of experiments has been conducted on the fuel atomizer with...
