This chapter focused on comparative studies on conventional, microwave and vacuum sintering of alumina-added stabilised zirconia yttria (YSZ). When energy and time savings are involved, microwave sintering has been found to be the most effective sintering technique. In contrast to the conventionally sintered ones, microwave and vacuum sintered specimens display improved densification at lower temperatures. […]

Conventional farming has posed a significant challenge to the quality of food, the climate and the quality of water. The key cause of soil quality deterioration in irrigated areas is insufficient and unbalanced application of agrochemicals (fertilisers, pesticides, herbicides and insecticides) to the soil and intensive soil tillage practises, resulting in stagnating or even declining […]

By taking 2-hydrazinobenzothizole as a staring substance, three compounds of 2-(benzothiazolyl-2′)hyrazino-5-arylidene-4-thiazolidinone derivative are prepared. But, both less aqueous soluble and biologically accessible are shown by the prepared compounds. Its inclusion complex is therefore prepared with β-cyclodextrin with an acceptable ratio after phase solubility studies to eradicate the problem. The experiment’s objectives are to make the […]

Pullulan and poly(vinyl alcohol) (PVA) miscibility studies blend through reduced viscosity measurements, refractometry, mechanical properties and SEM analysis. Viscometric measurements were performed at 30 and 40oC using the Ubbelohde viscometer. To test the ultrasonic velocities of different mix compositions, Ultrasonic Interferometric was used. The refractive indices of mixing solutions of different compositions were calculated directly […]

Due to their structural sophistication, chemical diversity, lack of significant toxic effects and a wide range of antimicrobial activity, conventional herbal medicines are new therapeutic candidates. It can be found in the Mediterranean, Africa, and India. Objective: To test and compare the in vitro antioxidant activity of the indigenous Withania somnifera methanol extract to that […]

In various fields of research, fluorescent dyes are used, such as in biochemical studies, medical diagnosis, photoelectric cell building, lasers and solar batteries. Some major fluorescent and photostability properties of Coumarin Disperse Yellow 82 are listed in this paper. The research aims to test the spectrophotometric fluorescence colour of Coumarin Diffuse Yellow 82. Spectral parameters […]

Due to its interesting structure and biological significance, Spiro compounds with attached indole moiety having an all-carbon quaternary stereogenic core have attracted synthetic organic chemists. In present work we have reported synthesis and characterisation of novel Hexahydrospiro [indoline-3,3′-pyrrolizine]-2-one derivatives in good to excellent yields through [3+2] cycloaddtion reaction in regioselective manner under ultrasonic irradiation. Via […]

During summer 2017, a comprehensive land resource analysis of the Gadagi-2 micro watershed, Lingasusgur taluk, Raichur district, Karnataka state, India, was conducted using a cadastral map overlaid on IRS Cartosat-1 merged with LISS IV satellite imagery at a scale of 1:8000. A detailed survey was initially conducted to derive soil phase/management units based on characteristics […]

Industry-based coloured organic dyes are often non-biodegradable, producing high toxicity to marine organisms and significantly disrupting the water environment. Due to their intrinsic properties, semiconductor photocatalysts have been employed to degrade textile dye contaminants. Using the simple and low-cost mechanochemical combustion process, CuO/ZnO nanocomposite photocatalysts were synthesised. In order to classify the prepared oxides, X-ray […]

Aims: In prokaryotes, eukaryotes, and lower plants, N-acetylglutamate (NAG) is the first intermediate in the arginine biosynthetic route. As a model for bond cleavage in living systems, the hydrolysis of amides is very significant in biochemistry and has been studied experimentally and theoretically to study N-acetylglutamate hydrolysis under acidic and basic conditions, using techniques of […]
