Formation, Analysis and Characterization of Wood Pyrolysed Oil
Abstract: Pyrolysis of wood is the possible path for converting biomass to higher valuable products such as bio-oil, bio-char and bio-gas. Bio-oil or liquid bio-fuels have higher heating values, so it can store and transport more conveniently the by-products bio-char and bio-gas, which can be used to provide heat required in the process. This work is focused on the formation, analysis and characterization of bio-oil which was obtained from the mixed …

The Developed System of Continuous Utilization of Carbon Dioxide, Enrichment of the Atmosphere with Oxygen and Production of Biofuel Using the Resulting Concentrate of Rapidly Multiplying Microalgae
Abstract: It is known that microorganisms, such as microalgae, during photosynthesis utilize carbon dioxide and enrich the atmosphere with oxygen. Microalgae, on the other hand, can be converted into biofuels by extracting fatty acids from macromolecules known as lipids. Recovery of this fatty acid traditionally requires the removal of most of the water from the microalgae resulting in biomass slurry. The method developed earlier permitted to obtain a high-quality concentrate of …

Ru(III)-Catalyzed Oxidative Cleavage of Ritodrine Hydrochloride: A Kinetic and Mechanistic Study
Abstract: A systematic kinetic and mechanistic study of the oxidation of ritodrine hydrochloride (RTH) with chloramine-T (CAT) in both HClO4 and NaOH media has been carried out at 303 K. In acid medium, the reaction rate is very sluggish to be measured kinetically. Ruthenium (III) chloride ([Ru(III)]) was found to be an efficient catalyst. The reaction rate exhibits a first-order dependence on [CAT]0 in both media. It shows a fractional-order on …

Aerosol to Suggest Climate Delineation
Abstract: Marine aerosol of submicron sized biogenic originated organic fraction is subtending persistently constitutively compared to drastic variation based on volcanic eruptions. Sulphur is studied to form acid aerosol where the basic constituent in the stratosphere is reduced comparatively. High concentrations of organic fraction have been found from aerosol in marine boundary layer (MBL). Marine aerosol chemical composition has been influenced by the yearly biological cycle of the ocean, and so …

Preliminary In Silico Analysis of Choline Monooxygenase and Betaine Aldehyde Dehydrogenase from Suaeda monoica Forssk. and its Expression in E. coli.
Abstract: AbstractIn a tropical country like India, the yield of crop plants is majorly affected by soil salinity and drought. One of the strategies to address this problem is by introducing genes responsible for salinity/drought tolerance in crop plants. Such genes could be identified and isolated from mangrove plants, as they are known to have evolved certain physiological mechanisms to augment saline environments. One such mechanism is the accumulation of Glycine …

The Patterns of Enamel Rod after Exposure to Probiotic Beverages
Abstract: Probiotic beverages have a taste of acid that is produced by fermentation of probiotic bacteria. The acid condition can affect the structure of tooth enamel. The structure of tooth enamel is formatted by enamel prism that is composed by hydroxyapatite (HA) crystals. According to several studies, HA has a critical pH <5.5 and can be changed in 180 min by acid. The objective of the study is to describe enamel …
