The Magnetically Impelled Arc Butt (MIAB) welding process uses a rotating arc as its heat source and is known as an efficient method for tube welding. Interaction of external magnetic field and induced magnetic flux results in the creation of Lorentz force along peripheral edges of tubes. The circumferential arc rotation helps in the uniform heating of faying surfaces. After sufficient melting, faying surfaces are pressed against each other for weld formation. This paper aims at studying the notch tensile properties of T11 tubes welded by MIAB welding. In MIAB welded T11 steel tubes various Thermo-Mechanically Affected Zones (TMAZ) are formed as an effect of heat and pressure during welding. Tensile properties of all these TMAZs are different due to varying microstructures. Therefore notched tension testing was carried out to compare the properties of various zones in welded T11 tubes. All TMAZs show higher notch ductility with Notch Strength Ratio (NSR) greater than one. In comparison to the base metal, all TMAZs except TMAZ III display no loss in notch strength. The presence of granular bainite in TMAZ III causes lower notch strength with a Normalized Notch strength (NTSN) ratio less than unity.

Pulses are one of the cheapest sources for the extraction of protein concentrates which can be gainfully utilized for meeting protein needs of specific groups. Techniques for maximum extraction of Pulse protein concentrates were developed for red gram and Bengal gram by standardisation of process parameters involving alkaline extraction followed by isoelectric precipitation. Extraction conditions viz., flour: water ratio – 1:10, pH 9 and stirring time- 4 hours were employed for isolation of the pulse protein concentrates. The protein concentrates extracted from red gram and chickpea were incorporated in ice cream formulations at concentrations of 5 and 10%. The pulse protein concentrate incorporated ice cream at 5% level had a higher sensory score of 8.7 and 8.8 on the nine-point hedonic scale compared to ice cream enriched with 10% pulse protein concentrate (8.4 and 8.5/9.0). The pulse protein enriched ice cream had a high protein content of 11.76 g/100 g compared to 4.90 g/100 g in control. Pulse protein concentrates have a wide food application in designing speciality foods for different age groups and disease conditions. The PPC incorporated protein enriched ice cream would provide for nutritious ice cream having desirable sensory properties with commercialisation prospects.

Ag doped CeO2 nanoparticles have been prepared by using green synthesized Ag and CeO2 nanoparticles. The formation of Ag doped CeO2 nanoparticles has been confirmed by SEM and EDAX analysis. Modified graphite Ag doped CeO2 electrode was prepared to study the biosensor using cyclic voltammetry method. The cyclic voltammetry was used as detection method to detect glucose in which the charge under the peak was calculated in a specific potential range. Methanol in PBS buffer (pH=7.0) was used as the flowing eluent. It is a pair of well-reversible redox reagents used as an electron-transfer mediator. Effect of scan rate, solution flow rate and buffer pH were also studied. The results show a small peak current due to the redox waves with formal potential at 1.705 volts. Here glucose oxidase undergoes catalytic oxidation. The current increases and creates the significant amount of electro catalytic current. This is due to the production of H2O2 by glucose oxidase enzyme during the oxidation of glucose.

Magnetically Impelled Arc Butt (MIAB) welding is a pressure welding process that uses the circumferential rotating arc to cause uniform heating of the faying surfaces. In this work, notched tensile testing of MIAB welded Carbon steel was carried out to determine the notch sensitivity of Thermo-Mechanically Affected Zones (TMAZ) and to compare the notch tensile property of these zones with the base metal property. In MIAB welding, after sufficient melting of the faying surface, a short pulse of high current is applied to expel the molten metal and impurities from the interface before welding. Insufficient expulsion and formation of Light Band (LB) zone at weld interface resulted in lower Notch Tensile Strength (NTS). Incomplete expulsion with lower upset current at the weld interface contributes to lower Normalized Notch Strength Ratio. Instead higher upset current contributed to higher NTS due to complete expulsion and stronger acicular ferrite formation. Other TMAZs away from the weld interface showed higher notch tensile strength with Notch Strength Ratio (NSR) and Normalized Notch Tensile Strength Ratio (NTSN) greater than unity.

Magnetically Impelled Arc Butt (MIAB) welding is a solid state welding process especially used in circumferential butt welding of tubes in which heat is generated prior to upsetting by an electric arc moving along the peripheral edges of the weldment with the aid of an external magnetic field. This paper aims at studying the formation of Light Band (LB) zone and its effect on the weld properties of MIAB welding of carbon steel tubes. A detailed microstructural analysis has been carried out to understand the microstructural transformations taking place in Thermo-Mechanically Affected Zone leading to formation of LB zone. Welded samples show better tensile properties with higher upset current as it eliminates LB zone formation at weld interface. For lower upset current, width of the LB zone increases with increase in arc rotation current resulting in lower weld tensile strength.

This paper represents an idea to track employee in highly active industries using mobile application. The majority of geographic positioning systems had been designed to operate within environments that have a long term stable macro structure with potential small scale dynamics. These assumptions enable the present positioning systems to supply and utilize maps. In extremely active industrial settings these assumptions are not valid and so the task of tracking employees is very difficult because of large scale changes in structure. In this project, an unique positioning system for following individuals in highly active industries such as construction sites, marketing and so on. However our system uses cross modality coaching in order to track the environmental changes by utilizing occlusion maps and how these maps can be used in conjunction with social forces to predict human movement and increase the tracking accuracy.

Magnetically impelled arc butt (MIAB) welding is a pressure welding process used for joining of pipes and tubes with an external magnetic field affecting arc rotation along the tube circumference. In this work, MIAB welding of low alloy steel (T11) tubes were carried out to study the microstructural changes occurring in thermo-mechanically affected zone (TMAZ). To qualify the process for the welding applications where pressure could be up to 300 bar, the MIAB welds are studied with variations of arc current and arc rotation time. It is found that TMAZ shows higher hardness than that in base metal and displays higher weld tensile strength and ductility due to bainitic transformation. The effect of arc current on the weld interface is also detailed and is found to be defect free at higher values of arc currents. The results reveal that MIAB welded samples exhibits good structural property correlation for high pressure applications with an added benefit of enhanced productivity at lower cost. The study will enable the use of MIAB welding for high pressure applications in power and defence sectors.

Biogenic silver nanoparticles (AgNPs) synthesized by Curcuma longa tube extract and characterized by UV–vis spectroscopy, XRD, TEM and FT- IR, Formation of AgNPs is initially confirmed by UV–vis spectroscopic studies with the specific band at 413 nm. TEM and XRD reports revealed that AgNPs are highly crystalline and rod shaped with average particle size of 30 nm. FT-IR studies indicated the presence of different functional groups on the surface of the AgNPs indicating the stability of AgNPs by capping of biomolecules onto the surface. Further, the bio-synthesized T-SNPs show significant anti-bacterial action on tested pathogenic microorganisms Further catalytic efficiency synthesized AgNPs were evaluated for the reduction/degradation of various organic dyes such as 4methylene blue (MB) and methyl orange (MO) using NaBH4 as reducing agent in the presence of catalytic amount of AgNPs. It was found that degradation was faster.

Magnetically Impelled Arc Butt (MIAB) welding is an unique forge welding process in which an arc is drawn in the gap between the two tubes to be welded in order to raise them to a high temperature to allow forging to form a solid state weld. This paper presents the investigations carried out on MIAB welding trials of carbon steel tubes with varying upset current. Upset current is the short pulse of high current applied prior to upset. It plays a significant role in expulsion of molten metal and impurity from weld interface. This study aims at studying the effect of upset current on weld properties. Carbon steel tubes of SA-210 Grade A have been chosen with outside diameter of 44 mm and thickness of 4.5 mm. Mechanical and microstructural characterization of MIAB weldments was carried out. Good correlation exists between the mechanical properties/microstructure and upset current. Lower upset current has detrimental effect on weld tensile strength due to incomplete expulsion of decarburized zone.

High strength low alloy (HSLA) steels are developed to provide better strength, toughness, and improved weldability. These steels are often used as better alternatives for quenched and tempered steels due to the excellent combination of these properties. The beneficial properties in these steels are achieved by careful control of composition and by adopting suitably controlled thermomechanical processing (TMCP). Improved weldability is achieved by maintaining carbon at lower level. To compensate the effect of carbon, small amounts of alloying elements, such as niobium, vanadium, titanium, aluminium, and nitrogen are added. Though these steels have good weldability, they suffer from hydrogen induced cracking especially at high strength levels. In the present study, hydrogen induced cracking susceptibility of a newly developed indigenous vanadium–titanium microalloyed high strength steel was evaluated by means of implant cracking test. Welding was carried out using the GMAW process at different heat input l...

An investigation on the feasibility of co-digesting Sewage Sludge with Palm Oil Mill Effluent for enhancing the biogas production and the corresponding effect of the co-digestion substrate ratio on the biogas production has been evaluated. Anaerobic co-digestion of POME with SS was performed at ratios of 100:0, 70:30, 60:40 and 0:100 to find the optimum blend required for enhanced waste digestion and biogas production. Single stage batch digestion was carried out for 12 days in a laboratory scale anaerobic digester. Co-digestion of sludge's at the 70:30 proportion resulted in optimal COD and C: N ratio which subsequently recorded the highest performance with regards to biogas production at 28.1 L's compared to the 1.98 L's of biogas produced from digestion of SS alone. From the results obtained, it is evident that co-digestion of POME and SS is an attractive option to be explored for enhancement of biogas production in anaerobic digesters.
