Characteristics of Bituminous Concrete Mixtures Utilizing Copper Slag
Study work on the effectiveness and use of Industrial by-products (IBP) in flexible pavements is restricted. Several factors however need to be analyzed specifically before a greater proportion of industrial by-products can be used in bituminous concrete mixtures with a high level of confidence. Effects of copper slag on volumetric and strength parameters such as Marshall Parameters, static tensile properties, and moisture resistivity of bituminous concrete mixtures using copper slag as mineral fillers need to be examined and thoroughly analyzed. Quantitative analyses of the elements and the morphology of the copper slag have been studied by Energy Dispersive X-ray Analyzer (EDX) and Scanning Electron Microscope (SEM). The use of copper slag as a mineral filler in bituminous concrete grade-2 mixtures showed an increase in stability, indirect tensile strength, and moisture resistance compared to traditional mixtures.
Keywords— Industrial by-products (IBP), Indirect Tensile Strength, Moisture resistivity, SEM, ED

Influencia del procedimiento de extracción en la actividad antioxidante de extractos de semilla de lenteja en un sistema modelo β-caroteno linoleato
Phenolic compounds were extracted from lentil seeds using three solvent systems: 80% (v/v) acetone, 80% (v/v) methanol, and 80% (v/v) ethanol. Each extract was subsequently separated into two fractions by chromatoghraphy on a column with Toyo Pearl HW-40 using water (fraction I) and methanol (fraction II) for elution. Antioxidative activity of extracts and their respective fractions were examined in a β-carotene-linoleate model system. All three extracts exhibited similar antioxidant activity. Considering the level of phenolic compounds in extracts it seems that phenolic compounds from the acetone extract were less active than those from either the methanolic and ethanolic ones. Because the content of phenolics was about 16-fold lower in fraction I of the methanolic and ethanolic extracts compared to fraction II, the phenolics in fraction I of the methanol and ethanol extracts from lentil seeds are much more active than these in fraction II. A stronger antioxidant activity of fraction I from the acetone extract compared to the crude acetone extract was observed during the latter incubation stage. The reason was a relatively high level of phenolic compounds in this fraction. UV spectra confirmed that the phenolic compounds from the acetone extract were different compared to methanolic and ethanolic extracts.Los compuestos fenólicos fueron extraídos de semillas de lenteja usando tres sistemas de disolventes: acetona del 80% (v/v), metanol del 80% (v/v), y etanol del 80% (v/v). Cada extracto fue separado posteriormente en dos fracciones por cromatografía en columna con Toyo Pearl HW-40 usando agua (fracción I) y metanol (fracción II) para la elución. La actividad antioxidante de los extractos y de sus fracciones respectivas fueron examinadas en un sistema modelo β-caroteno-linoleato. Los tres extractos exhibieron actividad antioxidante similar. Atendiendo al nivel de compuestos fenólicos en los extractos parece que los compuestos del extracto acetónico eran menos activos que los metanólicos y etanólicos. Debido a que el contenido de fenoles era aproximadamente 16 veces más bajo en la fracción I de los extractos metanólico y etanólico comparado con la fracción II, los fenoles en la fracción I de los extractos del metanol y del etanol de las semillas de lenteja son mucho más activos que éstos en la fracción II. Una actividad antioxidante más fuerte de la fracción I del extracto acetónico comparado con el extracto acetónico crudo fue observada durante el posterior periodo de incubación. La razón fué el relativamente alto nivel de compuestos fenólicos en esta fracción. El espectro UV confirmó que los compuestos fenólicos del extracto de acetona fueron diferentes comparados con los extractos metanólicos y etanólicos
HARDNESS PHENOMENON IN BEACH PEA (Lethyrus maritimus L.)
Beach pea is mostly grown on seashores and it contains higher amount of protein than other legumes. However, the pea has several undesirable attributes, such as long cooking time and hard to germinate (imbibitions) that limited its use as food. The present investigation aimed to study the physico-chemical properties, cooking characteristics and hull crude fibre structure of beach pea as compare to other similar legumes. Standard methods of processing pulses were used for present study. Beach pea seeds contained very low grain weight, density, hydration capacity, hydration index, swelling capacity and swelling index than the green pea and field pea. Beach pea had higher amount of crude protein, ash, crude fibre and polyphenols, but lower in starch content than the green pea and field pea. Without any treatment to beach pea seeds the water uptake capacity was very low. Mechanical treatment to beach pea seeds increasedthe water uptake percentage. The recovery of hull was 3 to 6 times higher in beach pea than that of green pea and field pea. The crude protein content in beach pea hull was 2-5% higher than others. The beach pea hull, dhal and whole seeds were good source of macro- and micro- minerals than that of the other two peas. The electron microscopic structure of beach pea hull crude fibre showed a very close and compact structure than green pea and field pea hull crude fibre structure. Lowering the hardness of beach pea seeds with mechanical or chemical treatments will give more scope for their utilization in the human nutrition

Demographic and Behavioural Segmentation of Tourist at Pilgrimages in Satara of Maharashtra State
Paper aims to understand demographic and behavioural tourist segmentation at pilgrimage destinations of Satara district. There are places known for pilgrimage however, 3 well-known destinations viz. Aundh, Wai and Sajjangarh are selected for study. Structured schedule executed to interview 97 tourists at tourist sites. Descriptive and Multivariate statistical tools are used i.e. two step cluster analysis to determine the segmentation. Hypotheses proposed to test viz. There is significant difference among the demographic variable of the sample. ANOVA was used to test the hypothesis. The results show that there is significant difference in the demographic variables available in sample data. Based on demographic variables two clusters were sorted and based on behavioural pattern 2 clusters found at Wai and Sajjangarh and 3 at Aundh. Scale of demographic variable cluster quality is just adequate at all pilgrimage centres. However at behavioural based quality scale is poor at Wai, satisfactory at rest of the destination. Demographic profile denote that majority of tourist come from other than Maharashtra, family tourist, Day visitors, repeaters found more and majority have used personal car to visit the sites.. Friends and relatives reference used to know the site

Effect of change in position of particle dampers on wind turbine blade for vibration suppression
Wind turbine energy minimizes due to vibration of blade. In this research we focus on vibration suppression by using particle damping technique. Containers are used for fill the particles and mounted on the blade. As vibration of blade increases, it increases the movement of containers along with particles this brings particle to particle and particle to container wall collision takes place which results to energy loss. In this study we use four different positions for mounting containers, firstly on all four different positions we mount containers simultaneously and take three readings for three different ball sizes respectively, keeping 50 % fill constant in all readings. Then we reduce one container among four and take the readings. Repeat this procedure up to single container. Compare with damping results with without damping results and finding out optimum locations for mounting of dampers
