Biscuits and rusks are one of the most popular bakery products with limiting various nutrients and ietary fibers. Diccocum wheat flour is rich in minerals, vitamins and fiber contents. In present investigation attempts have been made to assess the functional properties and proximate composition of malted and unmalted dicoccum flours which were analyzed by AOAC method and sensory appraisal of malted flour based baked products by 9- point hedonic scale. The result showed that all the functional and proximate composition of malted flour revealed that water absorption capacity (57.2±0.01%), oil absorption apacity (216±0.05%), bulk density (0.56±0.03g/cm3), swelling capacity (5.71±0.11%) whereas protein (15.60±0.31g/100g), crude fiber (2.80±0.07 g/100g), calcium (18.40±0.28 mg/100g) and iron (10.19±0.29 mg/100g) were significant at P ≤ 0.05 when compared to unmalted flour. The attempts also have been made to develop nutrient rich biscuits and rusks by addition of optimized proportions of wheat and malted dicoccum flour in different combinations. Biscuit and rusk sample (80:20) malted flour had the highest organoleptic scores in all attributes and also the functionality of the flour was not affected. The finding suggests that malted dicoccum flour had higher nutritional value than unmalted flour. Thus, malted dicoccum flour value added bakery products were develop to expand its utilization that would help in maintaining health and good source of instant snack for all age groups due to its high nutritiver value.

Biomonitoring of particulate pollution through magnetic properties of tree leaves has been suggested to be a good approach to measure air pollution levels. In the present study, three horticulturally important tree leaves (Artocarpus heterophyllus, Psidium guajava and Mangifera indica) were sampled in the city area, urban area and rural area, in order to evaluate suitability of different species as passive dust collectors in magnetometry. Magnetic measurements [Magnetic susceptibility (χ), Anhysteretic remenent magnetization (ARM) and Saturation remenent magnetization (SIRM)] were found to be higher for Mangifera indica when compared with Artocarpus heterophyllus and Psidium guajava. Overall all values of magnetic measurements (χ, ARM and SIRM) decline in the following sequence: city area > urban area > rural area for all three plants. Magnetic particles are dominated by multidomain, magnetite like minerals. The results of the present study indicate that magnetic measurements of tree leaves are practicable for monitoring and determination of atmospheric pollution in Aizawl city. Biomonitoring of particulate pollution through magnetic properties of plant leaves is a rapid and inexpensive alternative to conventional atmospheric pollution monitoring.

Levels of physico-chemical parameters (Temperature, pH, Electrical conductivity, Dissolved oxygen, Total hardness, Salinity, Total acidity and Total alkalinity) were determined in the water samples collected from River Neyyar. The parameters were highly influenced by climate. The results of physico-chemical analysis showed that temperature, pH, electrical conductivity, total hardness, salinity and total alkalinity were high in the water samples during dry season. Seasonal variations in dissolved oxygen depended on the temperature of water body. pH and total acidity are inversely interrelated. There was a positive correlation among the parameters like temperature, pH , electrical conductivity, total hardness, salinity and total alkalinity. There was a negative correlation between dissolved oxygen and total alkalinity. The pH, electrical conductivity, total hardness, salinity and total alkalinity at stations VIII, IX and X were high and therefore water from these stations were not fit for domestic and industrial uses.
Fluoride concentration above the permissible limit (>1.5mg/l) in drinking water leads to human health hazards, such as dental and skeletal fluorosis affecting millions of people in many parts of India. It is therefore essential to remove the excess fluoride from drinking water. Fluoride can be removed from water by the method of adsorption. In the present study, adsorbent is prepared from the fruits of Emblica officinalis and studies were carried out for fluoride removal. Batch sorption studies demonstrate that the adsorbent prepared from the fruits of Emblica officinalis has a significant capacity for adsorption of fluoride from aqueous solutions. The parameters investigated in this study include pH, temperature, initial fluoride ion concentration, contact time and adsorbent dose. From this study, the adsorption of fluoride was found to be high at a pH of 5.5.

In order to assess the comparative efficiency of different phosphatic fertilizers on growth and yield of wheat, an experiment was conducted during Rabi (crop season) 2013- 2014 at Latif Experimental Farm, Sindh Agriculture University, Tandojam, Pakistan on wheat (cv. Kiran-95). All the cultural practices were applied according to crop requirement. Nitrogen was applied at the rate of 160 N kg ha-1 through urea. Phosphorus was applied at the rate of 85 P2O5 kg ha-1 through DAP, SSP, NPK and Zoraawar spectively, except control and potassium was applied at the rate of 60 K2O kg ha-1 through SOP fertilizer. Soil of the experimental area was heavy in texture, non-saline (EC=0.17 to 0.54 dSm-1), medium alkaline in reaction (pH=8.0 to 8.2), moderately calcareous (4.16 to 11.66 %) in nature, poor to medium in organic matter content (0.38 to 1.24%) and AB-DTPA extractable P (1.09 to 5.77 mg kg-1), however soil was rich in AB-DTPA extractable K (91.65 to 123.24 mg kg-1). Results showed that agronomic characteristics of crop varied with different P sources. Maximum tillers (450.64 tillers /m2) and 1000 grains wt: (55.50 g) were obtained at DAP source. Plant height (91.07 cm), spike length (11.66 cm), number of grains plant-1 (407.7), straw yield (5480 kg ha-1) and grain yield (4420.0 kg ha-1) were produced more with NPK source. Phosphorus content in straw (0.074%) and grains (0.447%) were higher with Zoraawar, however K content in straw was recorded more in NPK (5.044%) than other sources.
The objective of this study is to ascertain the degree of various pollutants in drain water of Mandakini river of Chitrakoot, Satna district (M.P.) India. The river flow spans up to approximately 65-70 km in Madhya Pradesh and Uttar Pradesh and finally it joins the river Yamuna near Rajapur of UP. Five sampling sites were established for the collection of water samples in three seasons (Pre-monsoon, Monsoon and Post-monsoon) during the year 2012-2013. Water samples were analyzed for physico-chemical analysis by taking various parameters viz temperature, pH, DO, BOD, COD, electrical conductivity, TDS, TSS, TS and chloride contents. The observed results were seasonally compared and found above the excessive permissible level in all seasons. The direct addition of drain water in the river is creating an alarming situation to the quality of the surface as well as underground waters.
