Trans Indian Inst Metals 2006, 59(5), 619-33.
Research and development work carried out to improve the performance of the oxygen lance in the LD steelmaking process is summarized. The available literature states clearly that the lack of control of the foamy slag and the augmentation of interfacial area creation between slag and metal are the major bottlenecks in running the process effectively for improved turn-down steel quality. The reasons for the existing lance design's inability to produce liquid metal droplets in the presence of slag foam are explained. In order to augment the droplet generation, a new oxygen lance with a central subsonic nozzle flow through which can be controlled, has been introduced and its blowing performances studied using numerical and water model studies. The numerical simulations reveal that the presence of the central jet does not induce jet coalescence and the jets follow their geometrical path. The interferences of the jets with the bath have further been analyzed by hydrodynamic model studies. It has been found that the droplet generation rate improves significantly due to the presence of the central jet. Further, it has been observed that controlling of the flow rate through the central hole can be used as an effective process control tool.

Galactomannan polysaccharide gum refers to Guar gum and is made by thermochemical treatment of the seed of Cyamposis tetragonoloba. Propoxylated derivatives of Galactomannan (HPG) are synthesized by the etherification reaction with nonionic propylene oxide reagent with Galactomannan gum. This modification can significantly improve the important properties of unmodified gum like alkaline stability, hydrophobic-ity, solubility, biostability etc. in context to their application in construction application. The adequate degree of molar substitution in propoxylated derivatives of galactomannan lead to excellent water retention properties which is most important parameter in most of the construction application. The propoxylated derivatives of Galactomannan improve the performance/workability when typically applied in tile adhesives, tile grouts, cement based wall putty, cement I gypsum based plaster, cement based texture plaster, cement I gypsum based crack filler, flooring and leveling compound etc. Due to its excellent thickening efficiency and pseudo plastic rheology behavior, this product helps to improve the sag resistance of plaster/ mortar during the application on vertical wall.

Trans Indian Inst Metals 2006, 59(5), 769-86.
Atmosphere in continuous annealing and galvanizing lines alters both composition and micro-structure of the surface and sub-surface of sheet steel. The formation and the morphology of the surface oxides of alloying elements in High-strength Interstitial-free, Dual Phase and Transformation-Induced Plasticity steels is strongly influenced by the furnace dew point, and the presence of specific film-forming oxides may result in surface defects and bare areas on galvanized sheet products. The present contribution reviews the progress made recently in understanding the selective formation of surface and subsurface oxides during annealing in hot dip galvanizing and conventional continuous annealing lines. The mechanisms involved reveal the fact that the surface and subsurface composition and microstructure influence galvanized sheet product surface quality.

Niobium, titanium and vanadium are added to high strength low alloy (HSLA) steels to provide grain boundary pinning, and strengthening, precipitates to help produce the desired fine-grained microstructure. Niobium and titanium segregate strongly between the liquid and solid phase during steel solidification, with vanadium and aluminium showing much more limited segregation behaviour. Hence, macro- and micro-segregation of niobium and titanium occurs during thick slab casting resulting in a spatial distribution of precipitates and solute element. This precipitate spatial distribution has significant effects on grain size development during processing (slab solidification, reheating and rolling) and can result in a bimodal grain size distribution (abnormally large grains in a matrix of smaller grains). This paper describes, for HSLA steels containing niobium levels between approximately 0.02 and 0.06 wt%, grain size development during slab solidification, reheating and rolling with particular emphasis on the effect of micro-segregation. The reheat conditions leading to a significantly bimodal grain size distribution are included. The effect of the microalloying precipitates, either directly or via their influence on grain size distributions, on the mechanical properties (strength and toughness) is also discussed.

Tendency to form unusually coarse plates of bainite at large driving forces and relatively low transformation temperatures. It seems that separately nucleated platelets which are in the same crystallographic orientation coalesce during prolonged growth. This leads to a markedly bimodal distribution of plate thicknesses, with the fine plates about 0.2 μm thick and the larger plates many micrometers thick. The latter are detrimental to the toughness, of strong steels.

Stamp charging is a unique pre-carbonisation technology which allows inferior grade or weakly coking coals to be converted into coke of high intrinsic quality. The adoption of the same has been a real boon to Tata Steel over the last 15 years and has been a major factor in Tata Steel becoming one of the lowest cost steel producers in the world. Over the years, the steel company has slowly and steadily gained a wealth of experience in fine tuning and optimizing this technology. One of the major learnings is the flexibility in selecting a coal blend for producing coke of acceptable quality, with minimum cost and without affecting the health of the batteries. The technology has the advantage of producing coke with higher yield compared to conventional top charging. In this paper, an effort has been made to discuss some of these learnings and also the future challenges which need to be addressed to gain further benefit from this versatile technology.

Reviews a novel one-step coating process that uses chemical bonding to enhance paint adhesion to metal surfaces and inhibit substrate corrosion. The in-situ phosphatizing coating (ISPC) process eliminates the need for potentially toxic pretreatment baths and other high-waste procedures that are found in traditional pretreatment methods. The ISPC technique combines surface pre-treatment and primer/topcoat in one-step finish that eliminates the health, safety, and waste disposal concerns of current metals-coating technology. Chemistry, adhesion mechanism, typical formulae, the processing, application, advantages, disadvantages and testing of lSPCs are discussed. Some examples of work conducted on performance testing are also described. Vast savings accrued from elimination of wastewater treatment, chemicals, labor, and steam, electricity from conventional phosphatizing processes are the significant highlights of this technology. In addition to this, the environmental protection is also achieved.

Inhibitive influence of Leucine on the corrosion of commercial mild steel in 1.0 M HC1 medium has been investigated by weight loss and polarization studies. The inhibition study has been made with the aid of Electrochemical impedance spectroscopic (EIS) data. The inhibition efficiency values determined by the above methods were in good agreement. A plot of 6 Vs log C for the adsorption on the mild steel surface is found to have a linear relationship. This observation clearly supports the fact that the adsorption of the compound on mild steel in acid medium obeys Temkin's adsorption isotherm. The polarization curves reveal that the corrosion is predominantly cathodic control. The inhibition is due to adsorption of the inhibitor at the cathodic sites followed by the formation of an insoluble film. The inhibitor chosen for the present study reduces the corrosion significantly by the way of entering the cathodic sites more effectively in 1 M HCl.

Inhibiting effect of N - cyclohexyl - N'- phenyl thiourea (CPTU) and N-naphthyl-N'- phenyl thiourea (NPTU) on the corrosion of mild steel in aqueous solution of 0.1 NH2SO4 have been demonstrated using potentiodynamic polarization technique. The polarization data have shown that these compounds act as efficient anodic inhibitors for mild steel. Adsorption of these compounds on the mild steel surface was found to obey Temkin's adsorption isotherm. Good inhibition efficiency (IE) was evidenced in both the compounds and it was found to vary with concentration of the inhibitors. The kinetic parameters of adsorption obtained reveal spontaneous adsorption and a strong interaction of the compounds on the mild steel surface.

Pollut Res 2006, 25(4), 677-83.
Diethyl phthalate (DEP) is an industrially important chemical and is widely used in cellulose ester containing plastics such as cellulose acetate and butyrate. Wide use of plastics containing DEP has been leading to contamination of soil and other environmental matrices. In this communication the degradation of DEP contaminated soil was studied in bio-slurry phase reactor. Effect of bioaugmentation using ETP microflora on the degradation of DEP was investigated and it was observed that more than 99% of the substrate was degraded within 48 hr of retention time in anoxic-aerobic-anoxic micro environmental conditions. The metabolites formed during the degradation were identified using sophisticated analytical techniques viz., thin layer chromatography (TLC), high performance liquid chromatography (HPLC), nuclear magnetic resonance (NMR) and mass spectrometry (MS). A metabolic pathway for the degradation of DEP in slurry phase reactor was proposed based on the results obtained.

Supplementary foods namely panjiri, burfi and ladoo were prepared using wheat flour as control and wheat flour supplemented with defatted soy flour (DSF) at 20%, 30% and 40% levels and were organoleptically evaluated fresh, after 15 days and one month storage. Control and two most acceptable levels of supplementation in each product were also analyzed for their proximate composition. Incorporation of DSF at 20% level resulted in an improvement in the sensory characteristics of all three products whereas increasing DSF to 40% resulted in significant decrease due to development of dark colour and burnt and bitter flavour. Non significant decrease was observed for sensory parameters between fresh and 15 days stored samples whereas the decrease was significant between one month stored samples and fresh samples. Products with 20% and 30% DSF had significantly higher moisture, crude protein, crude fibre and crude ash content than the control.

Prepares chicken pickle with different formulations and analyse them for chemical, microbiological, sensory qualities and cost of the product. The results indicated that the product was good upto three months and different treatments did not show any change in the prepared pickle. As far as chemical changes were concerned, the moisture and free fatty acid contents increased and fat, proteins and pH decreased during storage. The pickle was free from coliforms and salmonella. The microbial load increased when pH declined but there was no fungal and yeast colonies. It may be concluded that vinegar based pickle could be consumed upto three months whereas citric acid based pickles were hard in texture. However citric acid as a preservative gave good shelf life and retained the nutrients. The microbial counts during storage period were well within the permissible limit and there was non significant decline in sensory qualities. The chicken pickle is not available commercially and this can be taken up as an entrepreneurship for income generation by women in India.

Study on packaging of chopped carrot was undertaken to evaluate the effect of type of polymeric film, thickness and perforation level on its keeping quality under refrigerated storage conditions. The keeping quality was observed in terms of physiological loss in weight (PLW), decay, firmness and shrinkage. Based on these parameters, it was found that thickness and type of film, for packages having perforations, had no effect on the keeping quality parameters except PLW. Low density polyethylene, 100 gauge package with perforation area of 2.17 x 10-2 percent i. e. 4 holes of diameter 1.6 mm on each side of the LD-100 film package, having diamensions 20 cm x 18.5 cm, was found to be the best as this package increased the storage life to 14 days as compared to 8 days for control samples. Economic analysis suggested an increase in the cost of carrot as 70 percent, after minimal processing and packaging.

Learning about edible plants, processing of foods and medicine using location specific wisdom and conservation of food related resources has been in the large part due to incremental and cumulative learning among the societies living in close connection with nature. Looking to the importance of location specific traditional knowledge in processing of foods, a study was conducted among Monpa tribe of Thembang and Dirang circle of West Kameng district of Arunachal Pradesh. Data were collected using the participatory and conventional tools. The study demonstrates that Monpa tribe prepares a range of alcoholic beverages from finger millet (Eleusine coracana Gaertn.), maize (Zea mays Linn.), barley (Hordeum vulgare Linn.) and rice (Oryza. sativa Linn.). Traditional foods are mainly based on yak milk, soybean (Glycine max Merrill.), buckwheat (Fagopyrum esculentum Moench), Amaranthus, maize, barley, chilli and various indigenous of fruits and vegetables. The foods consumed by Monpa tribe are nutritionally rich and are compatible with their ethnicity. The variability in the altitude, diversities in the socio-cultural and ecological edges affect the preservation, selection and use pattern of ethnic foods. The types of foods used in daily diet also signify the knowledge and learning network of women, governed by many institutions like mila, lakpa & barter system and elders of society. Diversities in the culturally and nutritionally important foods have made possible the conservation of indigenous biodiversity. Social gathering and cultural occasions provide opportunity in sharing the foods and learning the related knowledge systems.

Documentation and utilization of traditional knowledge in the field of medicine, healing and biodiversity conservation has attained greater dimensions. Though rural folk of our countrty unknowingly use microorganisms for varied purposes, there is no major effort to document and protect them. The art of preservation and enrichment of vegetables by microbial systems, preserving microbial culture starter for beverage production and production of diverse traditional beverages from plant materials is commendable. Fish products, dye adhesives and dyes are obtained similarly. Traditional foods and beverages are also used therapeutically. Patent analysis of Indian traditional fermented products in Indian databases, viz. Ekaswa A, Ekaswa B and Patestate showed the presence of few patents in idli, kinema, and toddy. In the United States patent database, there are few patents in dahi, where the relevance knowledge from India is indicated. Search in the patent databases of Japan, Europe and global search of WIPO showed lack of patents in Indian traditional fermented products. There is ample scope for researching and protecting our traditional knowledge by the tools of Intellectual Property Rights and sharing of benefits with the indigenous people of our country.
