Now-a-days growth of digital data is increasing rapidly. Textual documents created and distributed on the Internet are changing in various forms. All these data or documents are not efficiently useful. We have to analyze large amounts of data in an effort to find correlations, patterns and insights that is nothing but data mining. To discover relationship between two or more variables in data we require data mining. Data mining have attracted huge attention with coming up need for turning such data into knowledge and useful information. Text mining is an important data mining technique. Text mining is one of the recent area for research, is defined as the process of extracting data from large amount of texts. It allows to structure and categorize the textual contents which are initially unstructured.Text mining includes the most successful technique to extract the effective patterns. In this paper we will discuss framework of text mining, techniques and methods to give effectiveness over information extraction in text mining.

Volume: 8 | Issue no: 1&2-2017 | Pagination: 80-92
Indian soils are poor in nitrogen. Nearly 1/3 rd of Indian soils are acidic. Food shortage in 1960s necessitated green revolution, ushering in the use of high dose of chemical fertilizers and poisonous plant protection chemicals adversely affecting the health of the soil. But long term use of these fertilizers causes degradation of soil, compaction and reduces soil fertility. Organic manures when incorporated into the soil it add nutrients it. Application of FYM improves soil fertility. Therefore, there is wide scope to its application. FYM contains almost all the essential nutrient required for soil. The addition of farm yard manure to the field is carried out traditionally. So there is scope of work to distribute the farm yard manure uniformly on the soil surface. By considering these aspects, an animal drawn manure spreader cum cart with electricity generation unit was design and fabricated.The research work and testing was undertaken at the site of the AICRP on UAE CAET, V.N.M.K.V., Parbhani.The developed Manure spreader consist a chassis having two iron wheels, axel assembly, bearing, flat type agitator, peg tooth agitator, body frame for mounting the trapezoidal shaped manure box, hitching system and tool box.The application rate of manure varies from 2.46 to 10.06 t/ha for varies in opining area of cover 0.04 m2 to 0.16m2. The co-efficient of variation of uniformity for manure distribution varied from 18 -20 per cent. The designed manure spreader cum cart gave desired manure application rate (9 ? 10t/ha) at an opining area of cover 0.16m2at the operational speed of 2.63km/hr and draft required was 637 N. The draft and power requirement of manure spreader were 637 N and 0.46 kW, respectively within the draft ability limit of pair of bullock.The field capacity and field efficiency of machine were 0.21 ha/hrand 84 per cent at operational speed 2.51 km/hr.The manure spreader cum cart was used for carting with 500 kg load on Tar road and Kaccha road by Red Kandhari bullocks. The draft observed for Tar road with no load and 500 kg load conditions by Red Kandhari bullocks was 37 and 41 kg. respectively. The draft observed on Kaccha road for no load and 500 kg load conditions was 40 and 48 kg, respectively by Red Kandhari bullocks. Speed observed on Tar road for no load and 500 kg load conditions by RK bullock was 4.29 and 3.88 km/hr, respectively. The speed on Kaccha road was 4.04 and 3.48 km/hr, respectively. Power observed for no load and 500 kg load conditions was 0.40 and 0.43, respectively for RK bullock on tar road. And 0.43 and 0.48 Kw for no load and 500 kg load conditions, respectively on Kaccha road for RK bullock.

Volume: 8 | Issue no: 1&2-2017 | Pagination: 71-73
India produced 7,43, 220 tones of areca nut (Areca catechu L.) from 44,5000 ha during the year 2014-15 (APEDA). Areca nut is an important component of the religious, social and cultural celebrations and economic life of people in India. Areca nut is also used in ayurvedic and veterinary medicines. The edible part of arecanut is its kernel. The kernel is well protected inside a fibrous husk. This husk needs to be removed while obtaining the kernel. Being fibrous nature of the husk, it is difficult to de-husk. Hence, it was necessary to find out the force required for pierce the husk. It was observed that the average force required to break wet arecanut (freshly harvested) was 11.20 KN. Whereas the average force required to break dried arecanut was 10.62 KN.

Agricultural sector is the most important sector for Indian economy, as majority of Indian population is engaged in agricultural occupation. The demand of food in India has increased because of rapid growth of population in recent. The land is either over used or under used without considering its potential and constraints for growing crops in India. This consequence brings a set of different problems like under agriculture production, land degradation, land use conflicts, etc. Population of the India is growing dramatically so farming community has to produce more in order to meet the growing demand of food under limited land recourses. Choosing the most suitable crop to be cultivated for high agricultural production is most difficult task for farmers. To produce more crop, selection of crop for particular land is very difficult task for farmers. Number of factors like climate, soil, topograpy, moisture and nutrient availability, rooting conditions and soil toxicity make farmer?s task further tough. Therefore, an attempt has been made to develop a decision making tool for farmers to select the appropriate crop for their land. National Bureau of Soil Survey Land Use Planning (NBSS-LUP) Criteria and Analytical Hierarchy Process (AHP) technique is used to develop this tool. The interface engine of formulated tool has been developed using Microsoft Visual Basic.NET programming language. This tool helps in classifying crops in four suitability classes viz. highly suitable, moderately suitable, marginally suitable and not suitable according to NBSS-LUP criteria. The system covers 46 varieties of crops covering Cereals, Pulses, Oil seeds, Fibre crops, Commercial crops, Plantation crops, Fruit crops, Medicinal and Aromatic plants and Spices. It is proposed to facilitate farmers for selecting crops as per availability of local climatic condition and soil fertility.

The research was carried out at Puriya Park Farm, K. K. Wagh College of Agricultural Engineering and Technology, Nashik, in October 2014. The performance of drip products manufactured by different companies viz., Company A, Company B and Company C was evaluated. Two NPC emitters of 4 lph and 8 lph were tested at operating pressure ranging from 0.5 to1.25 kg/ cm2 and one PC emitter of 4 lph discharge was tested at same operating pressure range. Also, the emission uniformity (EU) and co-efficient of uniformity (CU) of drip system was worked out. In 4 lph and 8 lph NPC drippers manufactured by Company A, discharge variation with respect to pressure was less as compare to standard discharge values of Company B and Company C. In 4 lph PC drippers manufactured by Company B, discharge variation with respect to pressure was very less as compared to standard discharge values of Company A and Company C.
Environmentally Sustainable Sand Mining Based Ongis Based Sediment Yield Estimation
Author:Shrikant Ojha And Sangeeta Choudhary
Volume: 8 | Issue no: 1&2-2017 | Pagination: 49-57
Rampant urbanization, which happens to be the major cause for sand demand is responsible for unsustainable extraction of sand from dried and sometimes even wet river beds. Demand for sand from construction sector in India is expected to grow from 630 million tonne in 2014 to 1.4 billion tonne in 2020 (material usage report). Out of different sources like, river sand, ocean sand, dessert sand, manufactured sand, the river sand is most preferred because of mineralogical properties and grain structure, easy local availability and low cost. This has led to rampant, regulated and unregulated, sand mining in most of the reservoirs and river beds. Though removal of sand/sediments from riverbeds and reservoir beds is essential to prevent shallowing and consequent widening of river bed and reduction of capacity of reservoir. In absence of yield estimation models sand mining leases are allotted where amount of sand mined is decided as 3m from river or 1 m above water table, whichever is less. This may not be environmentally sustainable and may lead of medium to long term changes in riverbed profile and consequent negative environmental impact.

Author:D. Ramesh Babu
Volume: 8 | Issue no: 1&2-2017 | Pagination: 39-48
Effects of frying temperature, frying time and pre-fry-drying time on kinetics of moisture loss and oil uptake during frying were studied. Colour development during frying were also measured in terms of Hunter L, a, b parameters. Onion slices of 3 mm thickness were used for frying at 135, 150 and 165oC. The experimental data on moisture loss and oil uptake were fitted to a first order exponential model and kinetic co-efficients for mass transfer were calculated. Kinetic co-efficients were found to increase from 0.595 - 0.803 min-1 for moisture loss and from 0.38 - 0.563 min-1 for oil uptake with increase in frying temperature. Temperature dependence of kinetic co-efficients for moisture loss and oil uptake values were described by Arhenious type equation with activation energies of 1.88 x 103 KJ/kg mol for moisture loss and 2.3 x 103 KJ/kg mol for oil uptake, respectively. As the pre-frydrying time increased from 0 to 60 min, kinetic co-efficients were found to decrease from 0.71 to 0.617 min-1 for moisture loss and 0.442 to 0.326 min-1 for oil uptake. 60 minutes pre-drying reduced the oil content by 22.88 per cent. The mathematical modeling of colour parameters with respect to time and of frying and pre-fry drying time shown best fit with polynomial equation of third order. Two distinct periods (colour development and degradation) of colour changes observed as indicated by Hunter a and b values. During colour development period Hunter a and b values increased with temperature indicating golden surface colour.
