Cow milk curd was prepared using 2% v/v of Streptococcus thermophilus DG1 and a mixed culture (0.5:1.5 v/v) of S. thermophilus DG1 and Lactobacillus plantarum and incubating at 37 C for 16 h. Soy milk curd was prepared using different ratios of lactic cultures as stated earlier and also a mixed culture containing S. thermophilus DG1, L. plantarum and Leuconostoc mesenteroides sub spp. mesenteroides in the ratio 1:1:1 v/v along with beet pulp (2% w/w) and incubating at 37 C for 18 h. This improved functional and probiotic properties of curd. Structural changes in curd samples during fermentation were observed by Scanning Electron Microscope (SEM). Soy milk curd showed loosened structure. The degradation of proteins into peptides and amino acids were evaluated by SDS PAGE and amino acid analysis. Maximum production of amino acids i.e. cystine, histidine and asparagine were observed in both the cow and soymilk after fermentation. © 2011 Association of Food Scientists & Technologists (India).

Idli is a traditional fermented rice and black gram based food. Idli batter is prepared by soaking polished parboiled rice and decorticated black gram for 4 h at 30± 1 °C in water. The soaked mass was ground using a grinder with adequate amount of water. The blend ratios of 2:1, 3:1 and 4:1 (w/w) batter were allowed for fermentation for different periods with the addition of 2% (w/w) of salt. The rheology of the product was assessed using a Brookfield Viscometer having disc spindles. Shear stress values were in the range of 0.22 and 4 Pa and reached a maximum value at 7 h of fermentation. The density, pH, and percentage total acidity of batter during fermentation for different blend ratios ranged between 0.93 and 0.59 gm cm? 3, 4.21 and 5.9 and 0.44 and 0.91% respectively. During fermentation, maximum production of riboflavin and thiamine were found to be 0.76 mg/100 gm and 0.73 mg/100 gm in 3:1 blend ratio of idli batter; and the folic acid content was found to be at a maximum of 0.75 mg/100 gm of idli batter after 10 h of fermentation. Digestibility in terms of amino N 2 content was analysed by formol titration. © 2010 Association of Food Scientists & Technologists (India).

Honne oil methyl ester (HOME) is produced from a nonedible vegetable oil, namely, honne oil, available abundantly in India. It has remained as an untapped new possible source of alternative fuel that can be used for diesel engines. The present research is aimed at investigating experimentally the performance, exhaust emission, and combustion characteristics of a direct injection diesel engine (single cylinder, water cooled) typically used in agricultural sector over the entire load range when fuelled with HOME and diesel fuel blends, HM20 (20% HOME+80% diesel fuel)-HM100. The properties of these blends are found to be comparable with diesel fuel conforming to the American and European standards. The combustion parameters of HM20 are found to be slightly better than neat diesel (ND). For other blend ratios, these combustion parameters deviated compared with ND. The performance (brake thermal efficiency (BTE), brake-specific fuel consumption, and exhaust gas temperature) of HM20 is better than ND. For other blend ratios, BTE is inferior compared with ND. The emissions (CO and SO) of HM20-HM100, throughout the entire load range, are dropped significantly compared with ND. Unburned hydrocarbon emissions of HM20-HM40, throughout the entire load range, is slightly decreased, whereas for other blend ratios, it is increased compared with ND. NO x emissions of HM20, throughout the entire load range, is slightly increased, whereas for other blend ratios, it is slightly decreased. The reductions in exhaust emissions together with increase in BTE made the blend HM20 a suitable alternative fuel for diesel fuel and thus could help in controlling air pollution. © 2011 John Wiley & Sons, Ltd.

Honne oil methyl ester (HOME), a nonedible vegetable oil has remained as an untapped new possible source of alternative fuel. The present research is aimed to investigate experimentally the performance, exhaust emission, and combustion characteristics of a DI diesel engine, when fueled with neat diesel (ND) and HOME. The injector opening pressure (IOP) is varied from 200 bar (manufacturer specified value) to 260 bar in steps of 20 bar. The combustion parameters of HOME (IOP 260 bar) are found to be very close to ND. For other IOPs, these combustion parameters deviated compared to ND. The performance (BTE, BSFC, and EGT) of HOME (IOP 260 bar) is almost the same as that of ND. For other IOPs, BTE is inferior compared to ND. The emissions (CO and SO) of HOME (IOP 260 bar) are dropped significantly compared to ND. HC emissions of HOME (IOP 240 bar) are slightly decreased, whereas for other IOPs, it is increased compared to ND. NOx emissions of HOME (IOP 200 to 260 bar) are slightly decreased. The reductions in exhaust emissions and increase in BTEmade HOME (IOP 260 bar) a suitable alternative fuel for diesel fuel and thus could help in controlling air pollution. © 2011 American Institute of Chemical Engineers Environ Prog, 32: 148-155, 2013.

Honne oil (tamanu) (H), a non-edible vegetable oil is native for northwards of Northern Marianas islands and the Ryukyu Islands in southern Japan and westward throughout Polynesia. It has remained as an untapped new possible source of alternative fuel that can be used as diesel engine fuel. Literature pertaining to use of vegetable oil in diesel engine with kerosene and dimethyl carbonate (DMC) is scarce. The present research is aimed to investigate experimentally the performance, exhaust emission and combustion characteristics of a direct injection (DI) diesel engine, typically used in agricultural sector, over the entire load range, when fuelled with neat diesel (ND) and blends of diesel fuel (D)/DMC/H/ kerosene (K). DMC/D/H/K blends have a potential to improve the performance and emissions and to be an alternative to ND. Experiments have been conducted when fuelled with H20 (20%H + 80%D), HK (20%H + 40%K + 40%D) and HKD5 (20%H + 40%K + 35D + 5%DMC) to HKD15 in steps of 5% DMC keeping H and K percentages constant. The emissions (CO, HC and smoke density (SD)) of fuel blend HKD15 are found to be lowest, with SD dropping significantly. The NO x level is slightly higher with HKD5 to HKD15 as compared to ND. The brake thermal efficiency of HKD5 to HKD15 is same and it is higher than that of ND. There is a good trade off between NO x and SD. Peak cylinder pressure and premixed combustion phase increases as DMC content increase.

The present work examines the use of a non-edible vegetable oil namely honne oil, a new possible source of alternative fuel for diesel engine. Highly viscous honne oil can be reduced by blending it with diesel fuel. A direct injection diesel engine typically used in agricultural sector was operated on neat diesel and a blend of 50% honne oil with 50% diesel fuel (H50). Injector opening pressure was changed to study the performance, emission and combustion characteristics. It was observed that increasing the injector opening pressure with H50 from the rated injector opening pressure (200 bar) increased the brake thermal efficiency and reduced CO, HC, and smoke opacity emissions. However, NOx emission was increased. With H50, ignition delay decreased as injector opening pressure increased. Improved premixed heat release rate were observed with H50 when the injector opening pressure was advanced. The best injector opening pressure was 240 bar for H50 based on brake thermal efficiency and emissions.

It is necessary to combine different technologies for implementing high performance distributed knowledge discovery systems. We think grids can offer an effective support to the implementation and use of parallel data mining systems. In the literature, an effort has been made to extract rare association rules with multiple minimum supports. This paper proposes the development of probability apriori multiple minimum support (PAMMS) algorithm to discover both frequent and rare and association rules in grid environment. Experimental results show that the proposed approach is efficient. © 2012 Springer India Pvt. Ltd.

In many real life applications of WSN, to monitor a wide inaccessible area, a large number of sensor nodes are deployed randomly over the region. When an event occurs, to identify the affected area immediately, it is necessary that the data and the locations of the affected nodes are reported to the sink node with minimum latency. In this paper, for 2D region, using some light-weight distributed in-node processing, a reduced set of boundary nodes are identified, which report to the sink node following the proposed routing strategy to minimize the latency. Simulation results show that compared to the earlier works, the proposed algorithm performs better in terms of the number of boundary nodes to be reported, accuracy of the estimated area and the packet latency with less neighborhood information and without any dependency on sensed data. © 2015 IEEE.

Use of pesticide is growing day by day and thus enhances the environmental pollution and hazards. Bioremediation of pesticides is a relatively new technology, which is going through intense study as of recent decades. The process is dealing either with the degradation of the pesticide molecule to smaller compounds, which may be toxic/non-toxic itself or the removal of the pesticide molecule by simple absorption/adsorption mechanism. Malathion is a widely used organophosphate pesticide. Often they are used in excess to their safe limit and they will leach from soil to surface and ground water thus causing health hazards. Malathion residue can be removed by any of the physical, chemical and biological methods but bioremediation was found to be more efficient tool for removal of the Malathion residue from soil and water. © 2010 Academic Journals Inc.

It is a difficult task to set rare association rules to handle unpredictable items since approaches such as apriori algorithm and frequent pattern-growth, a single minimum support application based suffers from low or high minimum support. If minimum support is set high to cover the rarely appearing items it will miss the frequent patterns involving rare items since rare items fail to satisfy high minimum support. In the literature, an effort has been made to extract rare association rules with multiple minimum supports. In this paper, we explore the probability and propose multiple minsup based apriori-like approach called Probability Apriori Multiple Minimum Support (PAMMS) to efficiently discover rare association rules. Experimental results show that the proposed approach is efficient. © 2011 IEEE.
